    -----------------------------------------------------------------------
    
    SUMMARY: Section 1006(e)(1) of the Oil Pollution Act of 1990 requires 
    the President, acting through the Under Secretary of Commerce for 
    Oceans and Atmosphere, to promulgate regulations for the assessment of 
    natural resource damages resulting from a discharge or substantial 
    threat of a discharge of oil. This final rule is for the use of 
    authorized federal, state, Indian tribe, and foreign officials, 
    referred to as ``trustees.'' Natural resource damage assessments are 
    not identical to response or remedial actions addressed by the larger 
    statutory scheme of the Oil Pollution Act of 1990. Assessments are not 
    intended to replace response actions, which have as their primary 
    purpose the protection of human health, but to supplement them, by 
    providing a process for restoring natural resources and services 
    injured as a result of an incident involving oil.
    
    EFFECTIVE DATE: The effective date of the final rule is February 5, 
    1996.

    SUPPLEMENTARY INFORMATION: The Oil Pollution Act of 1990 (OPA), 33 
    U.S.C. 2701 et seq., provides for the prevention of, liability for, 
    removal of, and compensation for the discharge, or substantial threat 
    of discharge, of oil (hereinafter referred to as ``incident'') into or 
    upon the navigable waters of the United States, adjoining shorelines, 
    or the Exclusive Economic Zone. Section 1006(b) of OPA (33 U.S.C. 
    2706(b)) provides for the designation of federal, state, Indian tribe, 
    and foreign natural resource trustees to determine if injury to, 
    destruction of, loss of, or loss of use of natural resources and 
    services has resulted from an incident, assess natural resource damages 
    for those injuries, present a claim for damages (including the 
    reasonable costs of assessing damages), recover damages, and develop 
    and implement a plan for the restoration, rehabilitation, replacement, 
    or acquisition of the equivalent of the injured natural resources and 
    services under their trusteeship. Section 1006(e)(1) of OPA (33 U.S.C. 
    2706(e)(1)) requires the President, acting through the Under Secretary 
    of Commerce for Oceans and Atmosphere, to promulgate regulations for 
    the assessment of natural resource damages resulting from incidents.
    
    Background
    
        Prior to issuing this final rule, NOAA published eleven Federal 
    Register Notices requesting information and comments on approaches to 
    developing natural resource damage assessment procedures. 55 FR 53478 
    (December 28, 1990), 56 FR 8307 (February 28, 1991), 57 FR 8964 (March 
    13, 1992), 57 FR 14524 (April 21, 1992), 57 FR 23067 (June 1, 1992), 57 
    FR 44347 (September 25, 1992), 57 FR 56292 (November 27, 1992), 58 FR 
    4601 (January 15, 1993), 59 FR 1061 (January 7, 1994), 60 FR 39804 
    (August 3, 1995), and 60 FR 43574 (August 22, 1995). NOAA conducted a 
    public meeting on March 20, 1991, and held four regional workshops 
    during 1991 in Rockville, Maryland; Houston, Texas; San Francisco, 
    California; and Chicago, Illinois, to learn of regional concerns in 
    assessing injury and restoration for coastal and inland waters. One 
    workshop held in Alexandria, Virginia, in November 1991, provided a 
    forum for early discussions of various economic issues likely to be 
    raised during the rulemaking process. In addition, on August 12, 1992, 
    NOAA held a public hearing on the issue of whether constructed market 
    methodologies, including contingent valuation, (CV), can be used to 
    calculate reliably passive use values for natural resources, and if so, 
    under what circumstances and under what guidance. On January 15, 1993, 
    NOAA published in full the report of a panel commissioned to evaluate 
    the reliability of CV. 58 FR 4601.
        NOAA published the proposed OPA rule on January 7, 1994 (59 FR 
    1061). The proposed rule contained a statement requesting specific 
    consideration of certain issues. Immediately after publishing the 
    proposed rule, NOAA held six regional meetings in January and February 
    of 1994. A seventh workshop was held in March 1994 in Washington, D.C. 
    NOAA then published an informational notice to summarize the concerns 
    raised in these workshops on June 22, 1994 (59 FR 32148).
        Based upon comments received in response to the proposed rule and 
    regional meetings, NOAA reproposed the rule on August 3, 1995 (60 FR 
    39804). Immediately after publishing the proposed rule, NOAA held two 
    conferences in August and September of 1995 to discuss the 1995 
    proposed rule.
        This final rule draws from the public issue-discussion process and 
    comments received to provide a natural resource damage assessment 
    process intended to meet OPA's goal of expeditious, cost-effective, and 
    feasible restoration of natural resources and services injured by 
    incidents involving oil.
        This preamble is organized as follows: the Introduction gives an 
    overview of the rule and is followed by a discussion of each of the 
    subparts of the rule. Subpart A provides a general introduction, 
    subpart B describes trustee authorities, subpart C gives definitions 
    pertinent to this rule, subpart D describes the Preassessment Phase, 
    subpart E describes the Restoration Planning Phase, and subpart F 
    describes the Restoration Implementation Phase. Finally, the preamble 
    provides a general summary of and responses to the comments on the 
    proposed rule.
    
    INTRODUCTION
    
    I. Goal of OPA: Focus on Restoration
    
        The goal of the Oil Pollution Act of 1990 (OPA) is to make the 
    environment and public whole for injuries to natural resources and 
    natural resource services resulting from an incident involving a 
    discharge or substantial threat of a discharge of oil (incident). This 
    goal is achieved through returning injured natural resources and 
    services to baseline and compensating for interim losses of such 
    natural resources and services through the restoration, rehabilitation, 
    replacement or acquisition of equivalent natural resources and/or 
    services. The purpose of this rule is to provide a framework for 
    conducting sound natural resource damage assessments that achieve 
    restoration under OPA.
        Under the rule, restoration plans developed with input from the 
    public and responsible parties form the basis of a claim for natural 
    resource damages. Final restoration plans are presented to responsible 
    parties for funding. In addition, the rule allows responsible parties 
    to implement trustee-approved and monitored restoration plans. Because 
    assessments will be conducted in the open, and responsible parties and 
    the public will have opportunities to be 
    
    [[Page 441]]
    involved in the planning process, it is expected that restoration will 
    be achieved more quickly, transaction costs will decrease, and 
    litigation will be avoided.
        NOAA believes that an assessment that focuses on evaluating 
    injuries relevant to feasible restoration alternatives and soliciting 
    public input in restoration planning will accomplish three major goals: 
    validating trustee determinations regarding those actions that will 
    make the environment and public whole; ensuring that appropriate 
    assessment procedures for determining restoration actions for a given 
    incident are followed; and reducing transaction costs. The rule 
    provides for the use of a range of appropriate and cost-effective 
    procedures for an assessment. Procedures to be used within the rule 
    must meet certain standards: they must be capable of providing 
    information of use in determining the type and scale of restoration 
    appropriate for a particular injury; the additional cost of a more 
    complex procedure must be reasonably related to the expected increase 
    in the quality and/or quantity of information provided by the more 
    complex procedure; and they must be reliable and valid for the 
    particular incident. Trustees must select the most cost-effective of 
    two or more equally appropriate assessment procedures.
        Restoration planning by federal trustee agencies is subject to the 
    requirements of the National Environmental Policy Act (NEPA) (42 U.S.C. 
    4321 et seq.), except when a categorical exclusion or other exception 
    to NEPA applies. The process identified in the rule mirrors the 
    decisionmaking process embodied in NEPA, without requiring 
    significantly different steps or products than those envisioned in OPA. 
    Recognizing that NEPA compliance requirements will vary among federal 
    agencies, and that state trustees may not be subject to NEPA, the rule 
    describes the general processes and products required under NEPA, and 
    provides guidance for integrating NEPA compliance into the assessment.
        Finally, NOAA has developed guidance documents on various aspects 
    of the assessment. These guidance documents are available in draft on: 
    preassessment, injury assessment, restoration, compensation formulas, 
    and NEPA compliance (citations for the documents are included in the 
    Bibliography at the end of this preamble). These draft documents are 
    available from the address at the front of this preamble. The guidance 
    documents are being prepared in conjunction with this rulemaking to 
    provide additional technical information to those performing 
    assessments under OPA and other interested members of the public. These 
    documents will not constitute regulatory guidance, nor will they have 
    to be followed for an assessment to be conducted in accordance with 
    this rule. The documents, in their final form, will be made available 
    through a public information distribution service, and will be 
    announced in a future Federal Register notice.
    
    II. Overview of the Restoration Planning Process Under the Rule
    
        The natural resource damage assessment process in the rule includes 
    three phases as outlined below: (1) Preassessment; (2) restoration 
    planning; and (3) restoration implementation.
    
    Preassessment Phase
    
        When notified by response agencies of an incident involving oil, 
    trustees must first determine threshold criteria that provide their 
    authority to begin the natural resource damage assessment, such as 
    applicability of OPA and risks to natural resources under their 
    trusteeship. Based on early available information, trustees make a 
    preliminary determination whether natural resources or services have 
    been injured. Through coordination with response agencies, trustees 
    next determine whether response actions will eliminate the threat of 
    ongoing injury. If injuries are expected to continue, and feasible 
    restoration alternatives exist to address such injuries, trustees may 
    proceed with the assessment.
    
    Restoration Planning Phase
    
        The purpose of the Restoration Planning Phase is to evaluate 
    potential injuries to natural resources and services, and use that 
    information to determine the need for and scale of restoration actions. 
    The Restoration Planning Phase provides the link between injury and 
    restoration. The Restoration Planning Phase has two basic components: 
    injury assessment and restoration selection.
    
    Injury Assessment
    
        The goal of injury assessment is to determine the nature and extent 
    of injuries to natural resources and services, thus providing a 
    technical basis for evaluating the need for, type of, and scale of 
    restoration actions. Under the rule, injury is defined as an observable 
    or measurable adverse change in a natural resource or impairment of a 
    natural resource service. Trustees must determine that there is: (1) 
    Exposure, a pathway, and an adverse change to a natural resource or 
    service as a result of an actual discharge; or (2) an injury to a 
    natural resource or impairment of a natural resource service as a 
    result of response actions or a substantial threat of a discharge. 
    Trustees must also quantify the degree, and spatial and temporal extent 
    of injuries. Injuries are quantified by comparing the condition of the 
    injured natural resources or services to baseline, where necessary.
    
    Restoration Selection
    
        Once injury assessment is complete, trustees must develop a plan 
    for restoring the injured natural resources and services. Under the 
    rule, trustees must identify a reasonable range of restoration 
    alternatives, evaluate and select the preferred alternative(s), and 
    develop a Draft and Final Restoration Plan, that considers public 
    comments. Acceptable restoration actions include any of the actions 
    authorized under OPA (restoration, rehabilitation, replacement, or 
    acquisition of the equivalent), or some combination of those actions.
        Restoration actions under the rule are either primary or 
    compensatory. Each restoration alternative considered will contain 
    primary and/or compensatory restoration actions that address one or 
    more specific injuries associated with the incident. Primary 
    restoration refers to actions taken to return the injured natural 
    resources and services to baseline on an accelerated time frame. 
    Natural recovery also must be considered under primary restoration, in 
    which no human intervention is taken to directly restore injured 
    natural resources and/or services to baseline. Alternative primary 
    restoration actions can range from natural recovery, to actions that 
    prevent interference with natural recovery, to more intensive actions 
    expected to return injured natural resources and services to baseline 
    faster or with greater certainty than natural recovery.
        Compensatory restoration includes actions to compensate for interim 
    losses of natural resources and/or services pending recovery. The type 
    and scale of compensatory restoration may depend on the nature of the 
    primary restoration action, and the level and rate of recovery of the 
    injured natural resources and/or services given the primary restoration 
    action.
        When identifying the compensatory restoration components of the 
    restoration alternatives, trustees must first consider compensatory 
    restoration actions that provide services of the same type and quality, 
    and of comparable value as those lost. If compensatory 
    
    [[Page 442]]
    actions of the same type and quality and comparable value cannot 
    provide a reasonable range of alternatives, trustees may consider other 
    compensatory restoration actions among the alternatives, so long as the 
    actions, in the judgment of the trustees, will provide services of at 
    least comparable type and quality as those lost.
        To ensure that a restoration action appropriately addresses the 
    injuries resulting from an incident, trustees must scale the action. 
    The approaches that may be used to determine the appropriate scale of a 
    restoration action include the resource-to-resource or service-to-
    service approach, and the valuation approach. The possible use of 
    contingent valuation (CV) and other stated-preference methods of 
    valuation to determine what scale of compensatory restoration provides 
    an equivalent value to the lost services avoids many problems 
    identified by commenters regarding the use of CV to calculate a dollar 
    value for the damages as included in the 1994 proposal.
        Under the resource-to-resource or service-to-service approach to 
    scaling, trustees determine the appropriate quantity of replacement 
    natural resources and/or services to compensate for the amount of 
    injured natural resources or services. Trustees must consider using the 
    resource-to-resource or service-to-service approach for actions that 
    provide natural resources and/or services of the same type, quality, 
    and value as those lost.
        In situations where trustees must consider actions that provide 
    natural resources and/or services that are of a different type, 
    quality, or value than the injured natural resources and/or services, 
    or where use of resource-to-resource or service-to-service scaling is 
    inappropriate, trustees may use the valuation approach to scaling. To 
    evaluate actions that provide services of a different type or quality, 
    trustees need a common measure to compare services lost and services 
    provided, such as the value per unit of service. Trustees first 
    calculate the value of the lost services and then determine the value 
    gained from different scales of the restoration action. Trustees then 
    select the scale of the restoration action under consideration that 
    would provide value equal to the value lost. Responsible parties are 
    liable for the cost of implementing the restoration action that would 
    generate the equivalent value, not for the calculated interim loss in 
    value.
    
    Selection of a Preferred Alternative
    
        The identified restoration alternatives are evaluated based on a 
    number of factors that include: (i) cost to carry out the alternative; 
    (ii) extent to which each alternative is expected to meet the trustees' 
    goals and objectives in returning the injured natural resources and 
    services to baseline and/or compensate for interim losses; (iii) 
    likelihood of success of each alternative; (iv) extent to which each 
    alternative will prevent future injury as a result of the incident, and 
    avoid collateral injury as a result of implementing the alternative; 
    (v) extent to which each alternative benefits more than one natural 
    resource and/or service; and (vi) effect of each alternative on public 
    health and safety. Trustees must select the most cost-effective of two 
    or more equally preferable alternatives.
        A Draft Restoration Plan will be made available for review and 
    comment by the public, including appropriate members of the scientific 
    community where possible. Public review and comment of the plan will 
    depend on the nature of the incident, and any applicable federal 
    trustee NEPA requirements. The Draft Restoration Plan will describe the 
    trustees' preassessment activities, as well as injury assessment 
    activities and results, evaluate restoration alternatives, and identify 
    the preferred restoration alternative(s). After reviewing public 
    comments on the Draft Restoration Plan, trustees must develop a Final 
    Restoration Plan. The Final Restoration Plan will become the basis of 
    claims for damages.
    
    Restoration Implementation Phase
    
        The Final Restoration Plan is presented to responsible parties to 
    implement or to fund the trustees' costs of implementing the plan, thus 
    providing the opportunity for settlement of damages claims without 
    litigation. Should responsible parties decline to settle a claim, OPA 
    authorizes trustees to bring a civil action for damages in federal 
    court or seek an appropriation from the Oil Spill Liability Trust Fund 
    for such damages.
    
    DISCUSSION
    
    Subpart A--Introduction
    
    I. Purpose
    
        The goal of the Oil Pollution Act of 1990 (OPA), 33 U.S.C. 2701 et 
    seq., is to make the environment and public whole for injuries to 
    natural resources and services resulting from an incident involving a 
    discharge or substantial threat of a discharge of oil (incident). This 
    goal is achieved through returning the injured natural resources and 
    services to baseline and through compensation for interim losses of 
    those natural resources and services from the date of the incident 
    until recovery.
        The purpose of this rule is to promote expeditious and cost-
    effective restoration of natural resources and services injured as a 
    result of an incident. To fulfill this purpose, the rule provides a 
    natural resource damage assessment process for developing a plan for 
    restoration of the injured natural resources and services and pursuing 
    implementation or funding of the plan by responsible parties. The rule 
    also provides an administrative process for involving interested 
    parties in the assessment, a range of assessment procedures for 
    identifying and evaluating injuries to natural resources and services, 
    and a means for selecting appropriate restoration actions from a 
    reasonable range of alternatives.
    
    II. Scope
    
        This rule may be used by designated federal, state, tribal, and 
    foreign natural resource trustees to determine appropriate actions to 
    restore natural resources and/or services injured by a discharge, or 
    substantial threat of a discharge, of oil into or upon navigable waters 
    or adjoining shorelines or the Exclusive Economic Zone of the United 
    States.
        The Secretaries of the Interior, Commerce, Agriculture, Defense, 
    and Energy are the primary federal natural resources trustees, although 
    in some circumstances, the heads of other federal agencies may act as 
    trustees of natural resources (see 40 CFR 300.600). The roles and 
    responsibilities of the various federal trustees regarding an 
    assessment vary according to their natural resource management 
    responsibilities and the susceptibility of various natural resources 
    and/or services to injury. Designation of federal trustees and broad 
    guidelines describing trustee functions are addressed in subpart G of 
    the National Oil and Hazardous Substances Pollution Contingency Plan 
    (NCP), 40 CFR part 300.600. For state trustees, most governors have 
    delegated trustee responsibilities to specific state or local agencies, 
    as provided under OPA.
        The process described in the rule is not intended to affect the 
    recoverability of natural resource damages when recoveries are sought 
    other than in accordance with this rule.
    
    III. Overview
    
        The rule describes three phases of a natural resource damage 
    assessment. The Preassessment Phase, during which trustees determine 
    whether to pursue restoration, is described in subpart D of the rule. 
    The Restoration Planning 
    
    [[Page 443]]
    Phase, during which trustees evaluate information on potential injuries 
    and use that information to determine the need for, type of, and scale 
    of restoration, is described in subpart E of the rule. The Restoration 
    Implementation Phase, during which trustees ensure implementation of 
    restoration, is described in subpart F of the rule.
    
    IV. Rebuttable Presumption
    
        Assessments performed by federal, state, or tribal trustees in 
    accordance with this rule receive the evidentiary status of a 
    rebuttable presumption provided by section 1006(e)(2) of OPA (33 U.S.C. 
    2706(e)(2)). NOAA interprets this presumption to mean that the 
    responsible parties have the burdens of presenting alternative evidence 
    on damages and of persuading the fact finder that the damages presented 
    by the trustees are not an appropriate measure of damages. This 
    presumption applies to all assessment procedures conducted in 
    accordance with this rule. However, where trustees use procedures that 
    are determined not to be in accordance with this rule, trustees will 
    not obtain a rebuttable presumption for that portion of the assessment. 
    Assessments performed by foreign trustees in accordance with this rule 
    are not entitled to a rebuttable presumption, as provided in section 
    1006(c)(1) of OPA (33 U.S.C. 2706(e)(1)).
    
    V. Coordination
    
    A. General
        Coordination among all parties affected by an incident is crucial 
    to an efficient and effective assessment. Coordination, in pre-incident 
    planning and throughout the assessment, can reduce time until 
    restoration is implemented and ensure that assessment costs are 
    reasonable. More detailed discussion of some aspects of coordination 
    appears in Appendix A at the end of this preamble.
    B. Coordination Among Trustees
        This rule encourages trustees with shared or overlapping 
    trusteeship to coordinate their assessment activities, including 
    coordination in pre-incident planning. Coordination among trustees will 
    avoid duplicative claims for damages, address shared trust natural 
    resource concerns, and result in more effective funding of assessment 
    work. When conducting joint assessments, trustees must designate a Lead 
    Administrative Trustee (LAT). The LAT should be selected by mutual 
    agreement of the trustees. The LAT's duties and responsibilities are 
    mainly administrative, unless all trustees agree otherwise. Depending 
    upon the circumstances of the incident, there may be co-LATs or 
    sequential LATs for different stages of the process. This rule 
    encourages trustees to consider using agreements, such as memoranda of 
    understanding (MOUs), to structure both pre-incident and incident-
    specific activities. Trustees may act independently when there is a 
    reasonable basis for dividing assessment responsibilities, so long as 
    there is no double recovery of damages. However, independent 
    assessments may not achieve prompt restoration of injured natural 
    resources and services and may not be in the best interests of the 
    parties involved.
    C. Coordination With Response Agencies
        Trustees must coordinate their activities conducted concurrently 
    with response operations with response agencies consistent with the NCP 
    and any pre-incident plans or MOUs. Coordination among trustees and 
    response agencies can result in reducing or eliminating natural 
    resource and/or service injuries residual to the cleanup. ``Response'' 
    refers to those actions taken under the NCP to protect public health 
    and welfare or the environment when there is a discharge or a 
    substantial threat of a discharge of oil, including actions to contain 
    or remove discharged oil from water and shorelines.
    D. Coordination With Responsible Parties
        Active and early involvement of responsible parties may eliminate 
    some of the problems trustees have encountered immediately following an 
    incident, such as lack of funding, personnel and equipment. In 
    addition, a joint trustee-responsible party assessment may be more 
    cost-effective and avoid duplicate studies. Thus, the rule requires the 
    trustees to invite the responsible parties to participate in the 
    assessment.
        The rule leaves determination of the timing and extent of 
    responsible party participation to the judgment of the trustees on an 
    incident-specific basis. While active responsible party involvement is 
    the preferred means of conducting assessments, it may not be 
    appropriate for trustees to delay assessment activities while 
    negotiating the terms of responsible party involvement.
        Trustees should extend the invitation to participate to known 
    responsible parties as soon as practicable, but not later than the 
    delivery of the Notice of Intent to Conduct Restoration Planning, 
    described in Sec. 990.44 of the rule. The invitation to participate 
    must be in writing, and a written response by the responsible parties 
    is required to confirm the desire to participate. Trustees and 
    responsible parties should consider entering into binding agreements to 
    facilitate their interactions and resolve any disputes during the 
    assessment. To maximize cost-effectiveness and cooperation, trustees 
    and responsible parties should attempt to develop a set of agreed-upon 
    facts concerning the incident and/or assessment. For example, 
    stipulated facts might concern the types of natural resources and 
    services injured, extent of injury or most appropriate assessment 
    procedures to determine injury and/or restoration needs, and how the 
    results of the procedures used will be interpreted.
        The scope of the participation by responsible parties must be 
    determined by the trustees The rule provides a number of factors that 
    may assist trustees in making this determination. These factors 
    include, for identified responsible parties, the willingness of 
    responsible parties to participate in the assessment and provide 
    funding for assessment activities, the ability of responsible parties 
    to conduct assessment activities in a technically sound and timely 
    manner and to be bound by the results of jointly agreed upon studies, 
    the degree of cooperation in response activities, and the actions of 
    the responsible parties in prior assessments. However, the rule 
    provides for a minimum level of responsible party participation that 
    consists of notice of trustee determinations required by the rule, and 
    notice and opportunity to comment on documents or plans that 
    significantly affect the nature and extent of the assessment. Increased 
    levels of participation by responsible parties may be developed at the 
    mutual agreement of the trustees and responsible parties; however, 
    final authority to make determinations regarding injury and restoration 
    rests solely with the trustees. Submissions by responsible parties will 
    be included in the administrative record. Trustees may end 
    participation by responsible parties who, during the conduct of the 
    assessment, interfere with the trustees' capability to fulfill their 
    responsibilities under OPA and this rule.
        The rule also provides that participating responsible parties may 
    formally request use of assessment procedures other than those that 
    have been selected by trustees as the most appropriate for the incident 
    and injury of concern. Responsible parties must identify specific 
    alternate procedures, and demonstrate that they meet the 
    
    [[Page 444]]
    requirements for acceptable assessment procedures provided in 
    Sec. 990.27 of the rule. In addition, because trustees will already 
    have made a determination that a different procedure is appropriate, 
    responsible parties must agree not to challenge the results of the 
    requested alternate procedure and agree to fund the alternate 
    procedure. Trustees may deny the request for alternate procedures on 
    the grounds that they are not technically feasible or scientifically 
    sound, are inconsistent with Sec. 990.27 of the rule, or could not be 
    completed in a reasonable time frame. Trustees must document the 
    request and their response in the administrative record.
        Trustees must document in the administrative record and Restoration 
    Plan the invitation for participation by the responsible parties, 
    briefly describe the nature and extent of the responsible parties' 
    participation, and briefly describe, if applicable, why the responsible 
    parties' participation was terminated.
    E. Coordination With the Public
        A major goal of OPA is to involve the public in the restoration 
    planning process. At a minimum, the rule requires that trustees provide 
    opportunities for public involvement after the trustees decide to 
    develop a restoration plan. The rule further encourages that trustees 
    involve the public in the assessment at any time earlier, if such 
    involvement is expected to enhance trustees' decisionmaking or 
    facilitate the restoration process.
        Depending on the nature of the incident and expected assessment 
    actions, public comment may be solicited at various stages to ensure 
    the best information base is available to the trustees. In highly 
    complex incidents, or those incidents that are expected to involve 
    multi-year efforts, trustees may have an opportunity to set up one or a 
    series of public meetings to ensure opportunity for public input. 
    Attendance should be encouraged by all parties that are involved, 
    participating, or interested in the incident.
        To the fullest extent practicable, trustees should involve the 
    public to:
        (i) Encourage a broad understanding of restoration and build trust, 
    thus allowing for quicker recognition and support of the restoration 
    process overall;
        (ii) Provide opportunities for joint fact-finding, improving the 
    collection of quality data; and
        (iii) Incorporate public concern, providing for more effective 
    restoration planning.
    
    VI. Considerations for Facilitating Restoration
    
    A. General
        Pre-incident planning and regional restoration plan development are 
    tools trustees should consider as means to enhance successful 
    restoration planning and implementation. These actions are not required 
    actions under the rule. More extensive discussion on these topics is 
    included in Appendix A at the end of this preamble.
    B. Pre-Incident Planning
        NOAA believes that commitment of time, funding, and personnel to 
    planning prior to an incident will help ensure that the assessment 
    results in technically sound and cost-effective restoration. Pre-
    incident planning activities may identify natural resource damage 
    assessment teams, establish trustee notification systems, identify 
    support services, identify natural resources and/or services at risk, 
    identify and develop working relationships with area and regional 
    response agencies and officials, identify available baseline 
    information, establish data management systems, and identify assessment 
    funding issues and options. Potentially responsible parties, cleanup 
    agencies, representatives of local natural resource management 
    agencies, and representatives of local environmental groups should be 
    included in pre-incident planning to the fullest extent practicable.
    C. Regional Restoration Planning
        OPA intends that restoration actions make the environment and 
    public whole for natural resource and/or service injuries resulting 
    from an incident. Where practicable, development of restoration plans 
    on an incident-by-incident basis is the preferred alternative to 
    accomplish this goal. However, for many incidents, including smaller 
    incidents, such incident-specific plan development may be impractical 
    and costly. Yet, the impact of small incidents may still represent a 
    significant concern for trustees, particularly where small incidents 
    may have cumulative impacts. Thus, to achieve OPA's mandate to restore 
    injured natural resources and services regardless of the type and scale 
    of those injuries, trustees are encouraged to identify existing 
    Regional Restoration Plans or other existing restoration projects that 
    may be applicable in the event of an incident. Regional restoration 
    planning may consist of compiling databases that identify existing, 
    planned, or proposed restoration projects that may provide appropriate 
    restoration alternatives for consideration in the context of specific 
    incidents. Plans or projects developed on a regional basis (e.g., 
    ecosystem, landscape, watershed, or any other basis) appropriate so 
    long as natural resources and/or services comparable to those expected 
    to be injured by an incident are addressed in the plans. In no event 
    may the use of a regional restoration plan or other existing proposed 
    restoration project violate OPA's limitation that natural resource 
    damages must be used solely to restore, rehabilitate, replace, or 
    acquire the equivalent of natural resources and services injured by an 
    incident.
    
    Subpart B--Authorities
    
    I. Relationship to the CERCLA Natural Resource Damage Assessment 
    Regulations
    
        The Department of the Interior (DOI) has developed regulations for 
    assessing natural resource damages resulting from hazardous substance 
    releases under the Comprehensive Environmental Response, Compensation, 
    and Liability Act of 1980 (CERCLA) (42 U.S.C. 9601 et seq.), and the 
    Federal Water Pollution Control Act (Clean Water Act) (33 U.S.C. 1321 
    et seq.). The CERCLA regulations are codified at 43 CFR part 11. The 
    CERCLA regulations originally applied to natural resource damages 
    resulting from oil discharges as well as hazardous substance releases. 
    This rule supersedes 43 CFR part 11 with regard to incidents covered by 
    OPA. Trustees who began assessments under the CERCLA regulations before 
    the effective date of this rule may complete those assessments in 
    compliance with the CERCLA regulations or they may elect to use this 
    rule to obtain the rebuttable presumption.
        If natural resources and/or services are injured by a discharge or 
    release of a mixture of oil and hazardous substances, trustees must use 
    43 CFR part 11 in order to obtain a rebuttable presumption.
    
    II. Relationship to the NCP
    
        This rule provides procedures by which trustees may determine 
    appropriate restoration of injured natural resources and services, 
    where such injuries are not fully addressed by response actions. 
    Response actions and coordination with damage assessment activities are 
    conducted pursuant to the National Oil and Hazardous Substances 
    Pollution Contingency Plan (NCP), 40 CFR part 300. 
    
    [[Page 445]]
    
    
    III. Prohibition on Double Recovery
    
        Trustees are subject to a prohibition on double recovery of damages 
    in section 1006(d)(3) of OPA (33 U.S.C. 2706(d)(3)). This rule 
    encourages trustee coordination as a means to avoid double recovery. In 
    general, the losses that trustees may estimate without the risk of 
    double recovery are:
        (i) The value of losses to all public uses of natural resources as 
    measured by changes in:
        (a) Monetized measures of utility or consumer surplus;
        (b) Fees or other payments collectable by the government or a tribe 
    for use of the natural resource by a private party; and
        (c) Any economic rent accruing to a private party because the 
    government or tribe does not charge a fee or price for the use of the 
    natural resource, provided such economic rent is not recovered under a 
    private cause of action; and
        (ii) In instances where the trustee(s) is the majority operator or 
    controller of a for-profit or not-for-profit enterprise, and the injury 
    to the natural resource results in a reduction of net income to such an 
    enterprise, that portion of the lost net income due the trustee(s) from 
    this enterprise resulting directly or indirectly from the injury to the 
    natural resource.
        Trustee claims for damages under this rule should not include:
        (i) Losses to the government for forgone taxes, because these are 
    transfer payments from individuals to the government; or
        (ii) Wages and other income lost by private individuals, except for 
    that portion of income that represents uncollected economic rent, where 
    these values may be the subject of lawsuits brought by the individuals 
    suffering the loss.
        Where restoration actions are scaled using the resource-to-resource 
    or service-to-service scaling approach, trustees should ascertain the 
    extent to which the restoration actions also compensate for losses 
    typically scaled with a valuation approach.
    
    IV. Compliance With NEPA and the CEQ Regulations
    
        Under this rule, the National Environmental Policy Act (NEPA) 
    applies to restoration actions taken by federal trustees, generally 
    becoming applicable when the trustees begin the process of developing a 
    Draft Restoration Plan under subpart E of this rule, except where a 
    categorical exclusion or other exceptions to NEPA apply. Thus, when a 
    federal trustee proposes to take restoration actions under this rule, 
    it must integrate this rule with NEPA, the Council on Environmental 
    Quality (CEQ) regulations on NEPA, and any NEPA regulations promulgated 
    by that federal trustee agency. In conducting the NEPA process 
    concurrently rather than consecutively with the assessment, federal 
    trustees are more likely to make the environment and public whole, 
    avoid delays in restoration, and reduce transaction costs.
        Likewise, certain state trustees may also have equivalent NEPA 
    requirements, usually referred to as State Environmental Policy Acts 
    (SEPA). Thus, where a SEPA applies to state trustees, they must 
    consider the extent to which this rule can be integrated with their 
    SEPA requirements. Although other trustees may not be bound by NEPA or 
    NEPA-equivalent requirements, the trustees may still find the 
    procedural planning process as defined under NEPA (or SEPA) useful in 
    facilitating restoration.
        The provisions of Sec. 990.23 of this rule strictly relate to NEPA 
    and federal trustees. The rule provides a brief description of the 
    general procedures and products that may be expected if a restoration 
    action is subject to a federal trustee's NEPA compliance requirements. 
    Federal trustees should refer to the CEQ regulations and their own 
    agency(ies) NEPA regulations for specific guidance regarding NEPA 
    requirements.
    D. Restoration Plans
    1. Purpose
        After selecting a restoration alternative, trustees must prepare a 
    Draft Restoration Plan. Development of a Draft Restoration Plan 
    provides a vehicle for informing the affected and interested public of 
    the results of the trustees' analyses and decisions, and encouraging 
    public review. Public review can also supplement expert peer review 
    when comments are solicited from various professional communities or 
    other knowledgeable persons.
    2. Draft Restoration Plan
        A Draft Restoration Plan should include:
        (i) A summary of injury assessment procedures used;
        (ii) A description of the nature, degree, and spatial and temporal 
    extent of injuries resulting from the incident;
        (iii) The goals and objectives of restoration;
        (iv) The range of restoration alternatives considered, and a 
    discussion of how such alternatives were developed and evaluated under 
    this rule;
        (v) Identification of the trustees' tentative preferred 
    alternative(s);
        (vi) A description of past and proposed involvement of the 
    responsible parties in the assessment; and
        (vii) A description of monitoring for documenting restoration 
    effectiveness, including performance criteria that will be used to 
    determine the success of restoration and need for interim corrective 
    action.
        When developing the Draft Restoration Plan, trustees must clearly 
    define plan objectives that specify the desired outcome to be 
    accomplished, and the performance criteria by which successful 
    restoration will be judged. Trustees should, at a minimum, determine 
    what criteria will constitute success such that responsible parties are 
    relieved of responsibility for further restoration actions or 
    necessitate corrective actions in order to comply with the terms of a 
    restoration or settlement agreement.
        Performance criteria include structural, functional, temporal, and/
    or other demonstrable goals that the trustees should determine with 
    respect to all restoration actions. For example, an agreement to create 
    new intertidal marsh habitat as compensation for a marsh injured by oil 
    could be described by performance criteria including the number of 
    acres to be created, location, elevation of new habitat, species to be 
    planted and details for planting such as density, and time frame in 
    which identifiable stages of the project should be completed.
        The types of parameters that should be addressed in monitoring 
    include duration and frequency of monitoring needed to gauge progress 
    and success, the level of sampling needed to detect success or the need 
    for corrective action, and whether monitoring of a reference or control 
    site is needed to determine progress and success. Reasonable monitoring 
    and oversight costs cover those activities necessary to gauge the 
    progress, performance, and success of the restoration actions developed 
    under the plan.
    3. Public Review and Comment
        Public review and comment of both Draft and Final Restoration Plans 
    will depend on the nature of the incident and any applicable federal 
    trustee NEPA requirements, as described in Secs. 990.14(d) and 990.23 
    of the rule, but must be sufficient to satisfy OPA's requirement for 
    public involvement in planning restoration. Thus, trustees should 
    consider such factors as the form of the involvement (e.g., a hearing, 
    notice, or solicited comments), extent of 
    
    [[Page 446]]
    public involvement (e.g., timing and frequency), and the forum for 
    communicating with the public (e.g., local papers, the Federal 
    Register, direct contacts to known interested parties).
    4. Final Restoration Plan
        After reviewing public comments on the Draft Restoration Plan, 
    trustees must develop a Final Restoration Plan. As part of the Final 
    Restoration Plan, trustees must consider comments on the Draft 
    Restoration Plan. In response to the comments, the trustees may need to 
    modify the restoration alternatives being considered, develop and 
    evaluate alternatives that have not been given serious consideration by 
    the trustees, supplement, improve, or modify the analyses, make factual 
    corrections, or explain why the comments do not warrant further trustee 
    response, citing the reasons to support the trustee position, and 
    possibly indicate the circumstances that would trigger reappraisal or 
    further response.
        In the Final Restoration Plan, trustees indicate the restoration 
    alternatives that will be implemented and include the information in 
    the Draft Restoration Plan. The format of the Final Restoration Plan, 
    which essentially follows that of the Draft Restoration Plan, should 
    clearly indicate any changes to the Draft Restoration Plan.
    
    V. Compliance With Other Applicable Laws and Regulations
    
        When taking actions under this rule or while response actions are 
    on-going, trustee field activities must comply with any applicable 
    worker health and safety considerations specified in the NCP for 
    response actions. Where an incident implicates trustees' statutory or 
    regulatory requirements in addition to those under OPA and this rule, 
    trustees should comply with those requirements. This requirement also 
    relates to all legally applicable state, local or tribal procedural 
    requirements. Compliance with any applicable laws, regulations, and 
    associated permits will help to minimize duplicative and conflicting 
    efforts. When following procedural requirements other than those 
    specified by OPA and this rule, trustees should identify those 
    requirements in the restoration plan. Applicable federal requirements 
    that may need to be considered include, but are not limited to: the 
    Endangered Species Act; the Coastal Zone Management Act; the Migratory 
    Bird Treaty Act; the National Marine Sanctuaries Act; the National 
    Historic Preservation Act; the Marine Mammal Protection Act; and the 
    Archaeological Resources Protection Act. The use of NEPA as a planning 
    process may facilitate compliance with other federal requirements.
    
    VI. Settlement
    
        Trustees may settle claims for natural resource damages under this 
    rule at any time, provided that the settlement is adequate in the 
    judgment of the trustees to satisfy the goal of OPA and is fair, 
    reasonable, and in the public interest, with particular consideration 
    of the adequacy of the settlement to restore, replace, rehabilitate, or 
    acquire the equivalent of the injured natural resources and services. 
    Settlements by federal trustees will generally be subject to approval 
    by the U.S. Department of Justice. Sums recovered in settlement of such 
    claims, other than reimbursement of trustee costs, may only be expended 
    in accordance with a restoration plan, which may be set forth in whole 
    or in part in a consent decree or other settlement agreement, that is 
    made available for public review.
        In determining the sufficiency of settlements to meet the public 
    interest test under other statutes, reviewing courts have afforded 
    broad deference to the judgment of federal agencies recommending such 
    settlements. Courts have looked to whether the agencies have considered 
    such factors as the benefits of early settlement as opposed to delayed 
    recovery through litigation, litigation risk, certainty in the claim, 
    and attitude of the parties toward the settlement, among other factors.
    
    VII. Emergency Restoration
    
        Emergency restoration actions should be considered in situations 
    where immediate action is necessary to minimize continuing or prevent 
    additional injury. Although emergency restoration actions may be 
    considered and implemented by trustees at any time throughout the 
    assessment, typically trustees begin evaluating the need for emergency 
    restoration during response. If response actions are still underway, 
    trustees, through their Regional Response Team member or designee, must 
    coordinate with the On-Scene Coordinator (OSC) before taking any 
    emergency restoration actions. Any emergency restoration actions 
    proposed by trustees should not interfere with on-going response 
    actions. Trustees must explain to response agencies through the OSC 
    prior to implementation of emergency restoration actions their reasons 
    for believing that proposed emergency restoration actions will not 
    interfere with on-going response actions.
        Trustees must provide notice to identified responsible parties of 
    any emergency restoration actions and, to the extent time permits, 
    invite their participation in the conduct of those actions, consistent 
    with the provisions of Sec. 990.14(c) of the rule. Trustees must also 
    provide notice to the public, to the extent practicable, of these 
    planned emergency restoration actions. The rule allows trustees to take 
    emergency restoration action only if such action is feasible, likely to 
    minimize continuing or prevent additional injury, and can be conducted 
    at a cost that is not unreasonable. Trustees must also notify the 
    public of the justification for, the nature and extent of, and the 
    results of emergency restoration actions within a reasonable time 
    following the actions. The means by which this notice is provided to 
    the public is left to the discretion of the trustees.
        The costs associated with evaluating, planning, and implementing 
    emergency restoration are recoverable costs.
    
    VIII. Use of Assessment Procedures
    
    A. Standards for Assessment Procedures
        The rule addresses OPA's goal of efficient, cost-effective, and 
    feasible restoration by requiring that assessment procedures be 
    tailored to the circumstances of a particular incident and the 
    information needed to determine appropriate restoration for that 
    incident. The rule requires trustees to determine that the most 
    appropriate procedures for an incident be implemented by specifying a 
    set of standards for acceptable procedures. These standards are 
    applicable to every assessment procedure used under the rule. To be 
    considered in accordance with this rule, assessment procedures must 
    meet all of the following standards:
        (i) The procedures provide assessment information of use in 
    determining the type and scale of restoration appropriate for a 
    particular injury;
        (ii) The additional cost of a more complex procedure is reasonably 
    related to the expected increase in the quantity and/or quality of 
    relevant information provided by the more complex procedure; and
        (iii) The procedures are reliable and valid for the particular 
    incident.
    B. Assessment Procedures Available
        This rule provides the use of a range of assessment procedures, 
    from field or laboratory procedures, to model- or literature-based 
    procedures, to a combination thereof. When practicable, assessment 
    procedures must be chosen that provide information of use in 
    determining the most appropriate alternative for restoring the injury 
    resulting from the incident. In addition, 
    
    [[Page 447]]
    when selecting assessment procedures, trustees should consider factors 
    such as the time and cost to implement the procedure, nature, and 
    spatial and temporal extent of injury and information needed to 
    determine and quantify injury, possible restoration actions for 
    expected injuries, and information needed to determine appropriate 
    restoration. If more than one procedure providing the same type and 
    quality of information is available, the most cost-effective procedure 
    must be used. A further discussion of procedures is given in Appendix B 
    to this preamble.
    
    Subpart C--Definitions
    
        Relevant definitions in OPA are repeated in the rule as a matter of 
    reference. Important terms and concepts that are either not explicitly 
    defined or described in OPA or that require further clarification are 
    discussed below.
    
    Baseline
    
        Baseline refers to the condition of natural resources and services 
    that would have existed had the incident not occurred. Although injury 
    quantification requires comparison to a baseline condition, site-
    specific baseline information that accounts for natural variability and 
    confounding factors prior to the incident may not be required. In many 
    cases, injuries can be quantified in terms of incremental changes, 
    rather than in terms of absolute changes relative to a known baseline. 
    For example, some procedures do not require site-specific baseline 
    information to quantify injury. Rather, the injury is quantified in 
    terms of incremental adverse changes resulting from the incident. 
    Counts of oiled bird carcasses can be used as a basis for quantifying 
    incremental bird mortality resulting from an incident.
        The rule does not distinguish between baseline, historical, 
    reference, or control data in terms of value and utility in determining 
    the degree and spatial and temporal extent of injuries. To the extent 
    that historical data, reference data, or control data can provide valid 
    information on which to base a determination of the conditions of the 
    natural resource and service in the absence of the incident, these 
    forms of data may effectively serve as baseline information.
        Types of information that may be useful in evaluating baseline 
    include:
        (i) Information collected on a regular basis and for a period of 
    time from and prior to the incident;
        (ii) Information identifying historical patterns or trends on the 
    area of the incident and injured natural resources and services;
        (iii) Information from areas unaffected by the incident, that are 
    judged sufficiently similar to the area of the incident with respect to 
    the parameter being measured; or
        (iv) Information from the area of the incident after a particular 
    natural resources or services have been judged to have recovered.
    
    Incident
    
        An incident is any occurrence or series of occurrences having the 
    same origin, involving one or more vessels, facilities, or any 
    combination thereof, resulting in the discharge or substantial threat 
    of discharge of oil into or upon navigable waters or adjoining 
    shorelines or the Exclusive Economic Zone. When a discharge of oil 
    occurs, natural resources and/or services may be injured by the actual 
    discharge of oil or response activities related to the discharge. When 
    there is a substantial threat of a discharge of oil, natural resources 
    and/or services may also be injured by the threat or response actions 
    related to the threat.
    
    Injury
    
        OPA authorizes trustees to recover damages for ``injury to, 
    destruction of, loss of, or loss of use of'' natural resources (section 
    1002(b)(2)(A) of OPA, 33 U.S.C. 2702(b)(2)(A)). Trustees must establish 
    that injury has resulted from an incident. Under this rule, injury is 
    defined as an observable (i.e., qualitative) or measurable (i.e., 
    quantitative) adverse change in a natural resource or impairment of a 
    natural resource service.
        There are two general bases for determining injury under this rule. 
    Trustees must either determine that:
        (i) The natural resource was exposed, there is a pathway connecting 
    the incident with the natural resource, and an adverse change to the 
    natural resource and/or service has occurred; or
        (ii) For injuries resulting from response actions or from a 
    substantial threat of a discharge of oil, an injury to a natural 
    resource or an impairment of use of a natural resource service has 
    occurred as a result thereof. Thus, under this rule, injury may result 
    from direct or indirect exposure to oil, as well as from response-
    related activities, and loss of services is explicitly included in the 
    definition of injury.
    
    Oil
    
        Under section 1001(23) of OPA (33 U.S.C. 2701(23)), the term 
    ``oil'' includes oil of any kind or in any form, including, but not 
    limited to, petroleum, fuel oil, sludge, oil refuse, and oil mixed with 
    wastes other than dredged spoil, but does not include petroleum, 
    including crude oil or any fraction thereof, which is specifically 
    listed or designated as a hazardous substance under subparagraphs (A) 
    through (F) of section 101(14) of CERCLA and which is subject to the 
    provisions of that Act.
        On July 9, 1975, the U.S. Environmental Protection Agency published 
    a Federal Register notice to affirm that non-petroleum oils, such as 
    fats and oils from animal and vegetable sources, are subject to oil 
    spill reporting, civil penalties, cleanup costs, and oil spill 
    prevention plan preparation and implementation under 40 CFR part 112 
    and other requirements of section 311 of the Federal Water Pollution 
    Control Act (33 U.S.C. 1321 et seq.). The U.S. Environmental Protection 
    Agency and U.S. Coast Guard have interpreted and administered section 
    311 as applicable to incidents of non-petroleum oils. While the 
    mechanism of injuries by non-petroleum oils may be different than that 
    of petroleum oils, it is evident, based on current literature, that the 
    nature of such injuries is similar (e.g., death) for both types of 
    oils. However, the rule provides guidance to allow consideration of 
    differences in the physical, chemical, biological, and other 
    properties, and in the environmental effects of such oils in 
    determining whether injuries result from an incident involving non-
    petroleum oils.
    
    Pathway
    
        Pathway is the medium, mechanism, or route by which the incident 
    has resulted in an injury. For discharges of oil, a pathway is the 
    sequence of events by which:
        (i) The oil travelled through various components of an ecosystem 
    and contacted the natural resource of concern; or
        (ii) Exposure to oil in one part of an ecosystem was transmitted to 
    the natural resource of concern, without the oil directly contacting 
    the natural resource.
    
    Reasonable Assessment Costs
    
        Reasonable assessment costs are costs that trustees incurred in 
    performing assessments in accordance with this rule. Trustees may 
    recover the reasonable assessment costs they incur under this rule even 
    if they ultimately determine not to pursue restoration, provided that 
    they have determined that actions undertaken were premised on the 
    likelihood of injury and need for restoration. Under the rule, 
    reasonable assessment costs also include administrative, legal, and 
    enforcement costs necessary to carry out this part, monitoring and 
    oversight costs, and 
    
    [[Page 448]]
    costs associated with public participation and indirect costs.
    
    Recovery
    
        Recovery is the return of injured natural resources and services to 
    baseline. This concept encompasses the inherent tendency for natural 
    resource and service attributes to vary over space and time.
        Projecting recovery involves determining the likelihood and rate at 
    which natural resources and/or services will return to baseline. The 
    availability and quality of baseline information can influence recovery 
    projections. Trustees should use the best available baseline 
    information that can be gathered relative to the incident and 
    associated injuries.
    
    Restoration
    
        Restoration is any action (or an alternative), or a combination of 
    actions (or alternatives), to restore, rehabilitate, replace, or 
    acquire the equivalent of injured natural resources and services.
        This rule includes the concepts of primary and compensatory 
    restoration. Primary restoration is any action (whether on-site, off-
    site, in-kind, out-of-kind) that returns injured natural resources and 
    services to baseline, while compensatory restoration is any action (or 
    an alternative) taken to compensate for the interim loss of natural 
    resources or services that occur from the date of the incident until 
    such natural resources and services have recovered to their baseline 
    condition. Trustees must consider, within the primary restoration 
    component, natural recovery, in which no human intervention is taken to 
    directly restore the injured natural resources and services. Depending 
    on the injury of concern, primary restoration actions may include 
    actions to actively accelerate recovery or simply to remove conditions 
    that would make recovery unlikely. The rule discusses types of primary 
    restoration actions that trustees may want to consider.
        For some injuries, the need for and scale of compensatory 
    restoration actions may depend on the range of feasible primary 
    restoration actions, but trustees should evaluate the need to seek 
    compensatory restoration for all demonstrable service losses that occur 
    from the onset of the incident. The rule requires that trustees 
    preferentially evaluate compensatory restoration actions that provide 
    the same type, quality, and value of natural resources or services as 
    those lost. Actions that provide services of comparable type, quality, 
    and value may be considered if required to generate a range of feasible 
    restoration alternatives for evaluation.
    
    Services
    
        Natural resource services are all functions that a natural resource 
    provides for another natural resource(s) or for the public. Natural 
    resource services may be classified as follows:
        (i) Ecological services--the physical, chemical, or biological 
    functions that one natural resource provides for another. Examples 
    include provision of food, protection from predation, and nesting 
    habitat, among others; and
        (ii) Public services--the public uses of natural resources or 
    functions of natural resources that provide value to the public. 
    Examples include fishing, hunting, nature photography, and education, 
    among others.
    
    Value
    
        Value can be measured in units of natural resource services or 
    dollar amounts. An individual's value of a good or service is 
    represented by the maximum amount of goods, services, or money that the 
    individual is willing to give up to obtain a specific good or service, 
    or the minimum amount of goods, services, or money that an individual 
    is willing to accept to forgo a specific good or service. The total 
    value of a natural resource or service includes the value individuals 
    derive from direct use of the natural resource, for example, swimming, 
    boating, hunting, or birdwatching, as well as the value individuals 
    derive from knowing a natural resource will be available for future 
    generations. In many contexts, particularly in markets, value is 
    represented in terms of units of money. However, value can be measured 
    using other measures, including units of a natural resource service.
    
    Subpart D--Preassessment Phase
    
    I. Purpose
    
        During the Preassessment Phase, trustees make critical 
    determinations that shape the remainder of the natural resource damage 
    assessment. Trustees determine, based on the circumstances of a given 
    incident, whether actions under OPA are justified and make preliminary 
    determinations regarding the type of injury assessment and restoration 
    actions that may be pursued.
        Other matters considered during the Preassessment Phase include 
    funding, data collection, opening the administrative record, and 
    inviting responsible parties' participation. Trustees may also consider 
    the applicability of the defenses to liability provided in section 1002 
    of OPA (33 U.S.C. 2702).
    
    II. Determinations
    
    A. Determination of Jurisdiction
        In order for trustees to proceed with any assessment activities 
    under OPA, certain conditions must be met:
        (i) An ``incident'' under OPA must have occurred (i.e., there has 
    been a discharge or substantial threat of a discharge of oil);
        (ii) The incident does not fall within exclusionary conditions set 
    forth in section 1002(c) of OPA (33 U.S.C. 2702(c)) (e.g., the 
    discharge was not permitted by federal permit); and
        (iii) Natural resources or services under the trusteeship of the 
    trustee may have been, or are likely to be, injured as a result of the 
    incident.
        Frequently, the first two conditions are determined by the response 
    agency. The U.S. Coast Guard, U.S. Environmental Protection Agency, or 
    a state response agency may have already made the determination that 
    OPA applies to the incident before notifying trustees. The third 
    condition, however, is necessarily determined by each trustee.
        If all of the conditions listed above are met, trustees may proceed 
    with preassessment actions. If any one of the conditions is not met, 
    trustees may not take additional action under this rule, except action 
    to finalize this determination. Trustees may recover all reasonable 
    assessment costs incurred up to this point provided that the first two 
    conditions above were met and actions were taken with the reasonable 
    belief that natural resources or services under their trusteeship might 
    have been injured as a result of the incident.
        A determination that OPA applies and that a trustee has 
    jurisdiction to act under OPA may trigger initiation of the natural 
    resource damage assessment process.
    B. Determination to Conduct Restoration Planning
    1. General
        The determination to be made by trustees in the Preassessment Phase 
    is whether it appears that restoration actions should be pursued by the 
    trustees. This determination depends on the following conditions:
        (i) Injuries have resulted, or are likely to result, from the 
    incident;
        (ii) Response actions have not adequately addressed, or are not 
    expected to address, the injuries resulting from the incident; and
        (iii) Feasible primary and/or compensatory restoration actions 
    exist to address the potential injuries.
        If all the conditions listed above are met, trustees may proceed 
    with 
    
    [[Page 449]]
    preassessment actions. If the trustees decide to proceed with the 
    natural resource damage assessment, the trustees must issue a Notice of 
    Intent to Conduct Restoration Planning, which is described below. If 
    any one of the conditions is not met, trustees may not take additional 
    action under this rule, except action to finalize this determination. 
    However, trustees may recover all reasonable assessment costs incurred 
    up to this point.
    2. Identifying Natural Resources and Services at Risk
        Determining whether natural resources and services are, or are 
    likely to be, injured requires that trustees consider the:
        (i) Circumstances of the incident. Factors to consider include 
    geographic location, condition of the vessel or facility, environmental 
    conditions;
        (ii) Characteristics of the discharge or substantial threat of the 
    discharge. Factors to consider include the type of oil, which may be 
    described by its physical and chemical parameters, source, time and 
    duration, and volume of the discharge;
        (iii) Characteristics of the natural resources. Factors to consider 
    include the natural resources in the area of the incident, the services 
    they provide, habitat and species types, seasonal implications on 
    sensitive life stages, and unique ecological components; and
        (iv) Potential for injury. Factors to consider include potential 
    for exposure, pathways, causal mechanisms, and availability of 
    assessment procedures and data to analyze these factors.
        Trustees must consider injuries resulting from the incident as well 
    as from actions taken to respond to the incident.
    3. Effectiveness of Response Actions in Eliminating Injury
        Once trustees determine that natural resources and/or services are, 
    or may be expected to be, injured as a result of the incident, trustees 
    must then determine whether these injuries are likely to be adequately 
    addressed through response actions. This analysis should also consider 
    whether restoration is required for injuries that occurred at the time 
    of the incident, even if injured natural resources and services are 
    expected to return to baseline as a result of response actions. If 
    response actions will not alleviate residual natural resource and/or 
    service injuries, trustees must determine whether there is a need and 
    potential for restoration actions to address initial or residual 
    injuries, and begin identifying these actions, to facilitate the 
    Restoration Planning Phase of the assessment.
    4. Early Identification of Potential Restoration Actions
        Potential restoration actions need to be identified as early in the 
    assessment as practicable. Such identification is needed to help 
    justify the decision to proceed with an assessment that will lead to 
    effective restoration actions, and provide the focus for designing 
    injury assessment studies that will produce useful information on the 
    type and scale of restoration needed. Considerations important to the 
    early identification of restoration actions include:
        (i) Potential nature, degree, and spatial and temporal extent of 
    injury, with or without restoration;
        (ii) Need and potential for restoration given the types of 
    injuries;
        (iii) Potential type and scale of restoration;
        (iv) Extent to which information relevant to determining 
    restoration needs is known;
        (v) Time, money, and personnel required and available to obtain 
    missing or additional information relevant to restoration; and
        (vi) Requirements imposed by other applicable laws, regulations, 
    and permits that would affect restoration.
    
    III. Data Collection During Preassessment Phase
    
        This rule allows trustees to conduct data collection and analysis 
    during the Preassessment Phase if such activities are reasonably 
    related to making the determinations required during this phase. The 
    purpose of data collection and analysis at this stage is to facilitate 
    the determination of whether natural resources and/or services have 
    been injured by the incident and may require some form of restoration. 
    Ephemeral information (i.e., information that may be lost if not 
    collected immediately) may also be collected during the Preassessment 
    Phase if the information is necessary for any stage of the restoration 
    planning process. In addition, information needed to design and 
    implement anticipated assessment procedures may be collected during 
    this phase. Data collection and analysis during this phase must be 
    coordinated with response actions, such that the collection and 
    analyses do not interfere with response actions.
    
    IV. Notice of Intent to Conduct Restoration Planning
    
        If the trustees determine that there is a reasonable likelihood 
    that injury has occurred as a result of the incident and feasible 
    restoration actions exist that would address these injuries, the 
    trustees may proceed with the assessment. If trustees decide to 
    proceed, they must prepare a Notice of Intent to Conduct Restoration 
    Planning, which documents the trustees' preassessment activities and 
    the basis for the decision to proceed. Depending on information 
    available at this early stage of the assessment, the notice may also 
    include a description of the trustees' proposed strategy to assess 
    injury and determine the type and scale of restoration. The contents of 
    the notice may vary, but will typically discuss:
        (i) The facts of the incident;
        (ii) Trustee authority to proceed with the assessment;
        (iii) Natural resources and services that are, or are likely to be, 
    injured as a result of the incident;
        (iv) Potential restoration actions relevant to the expected 
    injuries; and
        (v) If determined at the time, potential assessment procedures to 
    evaluate the injuries and define the appropriate type and scale of 
    restoration for the injured natural resources and services.
        The notice must be made publicly available. The means by which the 
    notice is made publicly available and whether public comments are 
    solicited on the notice is left to the discretion of the trustee.
        Trustees must also provide a copy of the notice to the known 
    responsible parties and invite their participation in the conduct of 
    restoration planning. As provided under Sec. 990.14(c) of the rule, the 
    determination of the timing, nature, and extent of responsible party 
    participation will be determined by the trustees on an incident-
    specific basis.
    
    V. Administrative Record
    
        An administrative record facilitates the restoration process by 
    providing a central repository for all materials relied upon by 
    trustees in making final determinations about restoration actions 
    appropriate for an incident. Thus, as administrative record should be 
    opened after trustees decide to proceed with restoration planning, and 
    concurrently with the development of the Notice of Intent to Conduct 
    Restoration Planning.
        The administrative record must contain sufficient information to 
    support review of the trustees' decisionmaking process. Depending on 
    the nature and extent of the incident, assessment, and restoration 
    planning process, the administrative record should include information 
    relied upon during the assessment, and required by this rule. Thus, the 
    administrative record should ordinarily include the Notice of Intent to 
    Conduct Restoration Planning, draft and final restoration 
    
    [[Page 450]]
    plans, and public comments; any relevant data, investigation reports, 
    scientific studies, work plans, quality assurance plans, and 
    literature; and any agreements not otherwise privileged among the 
    participating trustees or with the responsible parties.
        Federal trustees should maintain the administrative record in a 
    manner consistent with the Administrative Procedure Act, 5 U.S.C. 551-
    59, 701-06. The administrative record should be limited to final 
    documents when possible. Where no final document is available at the 
    time of selection of restoration actions, draft documents may be 
    included in the administrative record if they contain information not 
    found in other documents in the record, but which is considered by the 
    trustees in selecting a restoration action. Pre-decisional, 
    deliberative internal agency memoranda should be treated like draft 
    documents (and be excluded from the record) unless relied upon in 
    choosing restoration actions.
        Although this rule is silent on the standard of judicial review for 
    an assessment conducted in accordance with this rule, NOAA expects that 
    the administrative record will serve as the foundation for any judicial 
    review of such assessment.
    
    Subpart E--Restoration Planning Phase
    
    I. Purpose
    
        The purpose of the Restoration Planning Phase is to evaluate and 
    quantify information on potential injuries to natural resources and/or 
    services (injury assessment), and use that information to determine the 
    need for and scale of restoration actions (restoration selection). The 
    assessment is essentially a restoration scoping exercise, and the 
    various studies and analyses conducted during this phase should be 
    viewed from the restoration perspective. Potential assessment 
    activities should be examined carefully to ensure that the results will 
    be useful and relevant to restoration.
        Development of a conceptual linkage between injury and restoration 
    early in the natural resource damage assessment process should 
    facilitate and minimize the costs of the assessment by assisting the 
    trustees in focusing on the most relevant injuries to be included in 
    the assessment, designing studies that are relevant to restoration, and 
    planning appropriate restoration actions. The rule provides that 
    trustees may use a range of possible assessment procedures for injury 
    assessment and restoration planning (see the discussion of Sec. 990.27, 
    ``Use of Assessment Procedures'').
    
    II. Injury Assessment
    
    A. Purpose
        The goal of injury assessment, which includes determination and 
    quantification of injury, is to evaluate the nature, degree, and 
    spatial and temporal extent of injuries to natural resources and/or 
    services, thus providing a technical basis for evaluating the need for 
    and scale of restoration. While the basic steps discussed below are 
    applicable to all assessments, selection of approaches for 
    demonstrating exposure, pathway, and injury will be incident-specific.
        To determine injury under this rule, trustees must determine if:
        (i) The definition of ``injury'' is met; and
        (ii) (a) An injured natural resource has been exposed to the 
    discharged oil, and a pathway can be established from the discharge to 
    the exposed natural resource; and/or
        (b) Any injury to or impairment of a natural resource service has 
    occurred as a result of response actions or a substantial threat of a 
    discharge of oil. These steps for determining injury and related 
    concepts are described in more detail below.
    B. Injury Determination
    1. Definition of Injury
        Under this rule, trustees must determine if the definition of 
    ``injury'' has been met. ``Injury'' is defined as an observable or 
    measurable adverse change in a natural resource or impairment of a 
    service.
        Injury includes adverse changes in the chemical or physical quality 
    or viability of a natural resource. The simplest example is death of an 
    organism, but indirect, delayed, or sublethal effects may also 
    constitute injury. Potential categories of injuries include adverse 
    changes in: survival, growth, and reproduction; health, physiology and 
    biological condition; behavior; community composition; ecological 
    processes and functions; physical and chemical habitat quality or 
    structure; and services to the public.
        Although injury is often thought of in terms of adverse changes in 
    biota, the definition of injury under this rule is broader. Injuries to 
    non-living natural resources (e.g., oiled sand on a recreational beach) 
    as well as injuries to natural resource services (e.g., lost use 
    associated with a fisheries closure to prevent harvest of tainted fish, 
    even though the fish themselves may not be injured) may be considered.
        This list of potential adverse changes is not intended to be 
    inclusive of all injuries that trustees may evaluate.
    2. Exposure
        The purpose of the exposure portion of an injury assessment is to 
    establish whether natural resources came into contact with the oil from 
    the incident. Early consideration of exposure should help to focus the 
    assessment on those natural resources and/or services that are most 
    likely to be injured by an incident.
        Trustees must establish whether the natural resource came into 
    contact, either directly or indirectly, with the oil discharged from 
    the incident. Under the rule, exposure is broadly defined to include 
    not only direct physical exposure to oil, but also indirect exposure 
    (e.g., injury to an organism as a result of disruption of its food 
    web). Documenting exposure is a prerequisite to determining injury, 
    except for response-related injuries and injuries resulting from 
    substantial threats of discharges. However, evidence of exposure alone 
    may be insufficient to conclude that injury to a natural resource has 
    occurred (e.g., the presence of petroleum hydrocarbons in oyster 
    tissues may not, in itself, constitute an injury).
        Exposure can be established with either quantitative or qualitative 
    procedures. As with other elements of the assessment, selection of 
    procedures for establishing oil exposure will depend on the type and 
    volume of discharged oil, natural resources at risk, and nature of the 
    receiving environment. A combination of assessment procedures may be 
    necessary to determine exposure. For example, chemical analysis of oil 
    in sediments, alone, may not be adequate to conclude that a benthic 
    organism was otherwise exposed to the oil. Likewise, the presence of 
    petroleum in fish tissue, alone, may not be adequate to link the 
    exposure to the discharge because metabolism of the oil may blur its 
    chemical characterization. The combination of the two procedures may, 
    however, add to the weight of evidence establishing exposure.
        Trustees must determine the most appropriate procedures to evaluate 
    exposure on an incident-specific basis. For some types of incidents, 
    visual observation in the field and/or modeling may be adequate to 
    document exposure. For other incidents, more involved site-specific 
    sampling, including chemical analysis and biological data collection 
    and analysis, may be more appropriate.
    3. Pathways
        To determine whether an injury resulted from a specific incident, a 
    pathway linking the incident to the 
    
    [[Page 451]]
    injury must be established. As with exposure, establishing a pathway is 
    a prerequisite to determining injury, except for response-related 
    injuries and injuries resulting from a substantial threat of a 
    discharge. However, evidence of a pathway, alone, is not sufficient to 
    conclude that injury has occurred (e.g., demonstrating that prey 
    species are oiled can be used to document that a pathway to a predator 
    species exists; however, such data do not, in themselves, establish 
    that the predator species is injured).
        Pathway determination may include, but is not limited to an 
    evaluation of the sequence of events by which the discharged oil was 
    transported from the incident and either:
        (i) Came into direct physical contact with the exposed natural 
    resource (e.g., oil transported from an incident by ocean currents, 
    wind, and wave action to directly oil shellfish); or
        (ii) Caused an indirect injury to a natural resource and/or service 
    (e.g., oil transported from an incident by ocean currents, wind, and 
    wave action cause reduced populations of bait fish, which in turn 
    results in starvation of a fish-eating bird; or, oil transported from 
    an incident by currents, wind, and wave action causes the closure of a 
    fishery to prevent potentially tainted fish from being marketed).
        Pathway determination does not require that injured natural 
    resources and/or services be directly exposed to oil. In the example 
    provided above, fish-eating birds are injured as a result of decreases 
    in food availability. However, trustees must always determine the 
    existence of a pathway relating the incident to the injured natural 
    resource and/or service, if the injury is caused by direct exposure to 
    oil.
        Pathways may include, but are not limited to, movement/exposure 
    through the water surface, water column, sediments, soil, groundwater, 
    air, or biota.
        As with exposure determination, trustees must determine the most 
    appropriate procedures to evaluate whether a pathway exists on an 
    incident-specific basis.
        Understanding the potential pathways will also help to narrow the 
    scope of the assessment, and may be important in deciding which 
    assessment procedures to use. For example, if a particular procedure 
    does not address injuries that occur through air or terrestrial 
    pathways, it would not be appropriate to use that procedure in cases 
    where such pathways are predominant.
    4. Selection of Injuries to Include in the Assessment
        During the Preassessment Phase, trustees may collect information on 
    a wide range of potential injuries. As a result, a long inventory of 
    potential injuries resulting from the incident is often developed. 
    Because the collection of information on injury must be related to the 
    incident and consistent with restoration planning, developing 
    scientific knowledge for its own sake is not part of an assessment 
    under this rule.
        To compile an inventory of potential injuries to include in the 
    assessment, trustees should determine the extent to which the following 
    information is known or can be obtained for each injury:
        (i) Natural resources and services of concern;
        (ii) Kinds of procedures available to evaluate and quantify injury, 
    and associated time and cost requirements;
        (iii) Evidence indicating exposure;
        (iv) Pathway from the incident to the natural resource and/or 
    service of concern;
        (v) Adverse change or impairment that constitutes injury;
        (vi) Evidence indicating injury;
        (vii) Mechanism by which injury occurred;
        (viii) Potential degree, and spatial and temporal extent of the 
    injury;
        (ix) Potential natural recovery period; and
        (x) Kinds of primary and/or compensatory restoration actions that 
    are feasible.
        Analysis of the factors above should produce a list of injuries 
    appropriate to evaluate in the assessment.
    C. Injury Quantification
        Injury quantification is the process by which trustees determine 
    the degree, and spatial and temporal extent of injuries relative to 
    baseline. Thus, injury quantification typically provides information on 
    the scale of restoration that may be necessary.
    1. Injury Quantification Information Needs
        A variety of procedures for injury quantification may be available 
    to trustees. However, because the ultimate purpose of injury 
    quantification is ideally to facilitate the design and scale of 
    restoration actions, injury quantification should, at a minimum, 
    evaluate the following factors:
        (i) Degree of the injury. Degree may be expressed in terms such as 
    percent mortality, proportion of a population, species, community, or 
    habitat affected, extent of oiling, and availability of substitute 
    services.
        (ii) Spatial extent of the injury. Spatial extent may include 
    quantification of the total area or volume of injury.
        (iii) Temporal extent of the injury. Duration of injury may be 
    expressed as the total length of time that the natural resource and/or 
    service is adversely affected, starting at the time of the incident and 
    continuing until the natural resources and services return to baseline.
        In order to scale restoration actions, trustees may find it useful 
    to develop an estimate of the total quantity of injury that integrates 
    the degree, and spatial and temporal extent of injury. For example, 
    quantification of the total losses of wetland habitat injured by oil 
    could be obtained by estimating the total number of acres of severely 
    oiled wetland in which vegetation is totally killed, the natural 
    recovery time for severely oiled wetland, the total number of acres of 
    moderately oiled wetland in which vegetation is not completely killed 
    but the wetland has lower levels of productivity, and the natural 
    recovery time for moderately oiled wetland. This information could be 
    combined to quantify the total number of ``acre-years'' of wetland 
    injury to scale restoration actions.
    2. Conceptual Approaches to Quantification
        Trustees may pursue several different conceptual approaches to 
    injury quantification. Under these approaches, injury may be quantified 
    in terms of:
        (i) The degree, and spatial and temporal extent of injury to a 
    natural resource;
        (ii) The degree, and spatial and temporal extent of injury to a 
    natural resource, with subsequent translation of that adverse change to 
    a reduction in services provided by the natural resource; or
        (iii) The amount of services lost as a result of the incident.
        Examples of the first approach include quantifying the number of 
    fish or seabird mortalities caused by a discharge of oil. Examples of 
    the second approach include quantifying reductions in fish populations 
    with subsequent estimation of the reduction in the value of a 
    recreational fishing day lost, given the injury, or quantifying the 
    amount of lost spawning habitat as a result of oiling with subsequent 
    estimation of the number of fish that would have been produced by that 
    habitat. An example of the third approach includes direct measurement 
    of the number of beach user days lost as a result of a beach closure. 
    For a 
    
    [[Page 452]]
    particular injury, trustees should use whichever approach is most 
    appropriate to the circumstances of the incident.
    D. Analysis of Natural Recovery
        Natural recovery is a restoration alternative whereby injured 
    natural resources and services are allowed to return to conditions 
    prior to the incident without human intervention, following any 
    response actions. Under this rule, trustees must estimate the time for 
    natural recovery in order to quantify injury. Analysis of recovery 
    times may include such factors as:
        (i) The nature, degree, and spatial and temporal extent of injury;
        (ii) The sensitivity and vulnerability of the injured natural 
    resource and/or service;
        (iii) The reproductive and recruitment potential;
        (iv) The resistance and resilience (stability) of the affected 
    environment;
        (v) The natural variability; and
        (vi) The physical/chemical processes of the affected environment.
        Although it is desirable to account for these factors and produce a 
    rigorous quantitative natural recovery estimate for a particular 
    natural resource, this may not be practicable for many injuries. As 
    with any assessment procedure used under the rule, the most appropriate 
    procedure that meets the standards for acceptable procedures in 
    Sec. 990.27 of the rule must be used for estimating natural recovery. 
    Thus, under this rule, where quantitative procedures are lacking, 
    inadequate, or unnecessarily costly to precisely estimate natural 
    recovery times, trustees may use appropriate qualitative procedures to 
    develop estimates where needed.
    
    III. Restoration Selection
    
    A. Purpose
        Once injury assessment is completed, trustees must develop a plan 
    for restoring the injured natural resources and services. Under this 
    rule, trustees must identify a reasonable range of restoration 
    alternatives, evaluate those alternatives, select an alternative, 
    develop a Draft Restoration Plan, and produce a Final Restoration Plan.
        If the information on injury determination and quantification and 
    its relevance to restoration justify restoration, trustees may proceed 
    with restoration planning. Otherwise, trustees may not take additional 
    assessment actions. However, trustees may recover all reasonable 
    assessment costs incurred up to this point.
    B. Developing a Reasonable Range of Alternatives
    1. General
        Trustees must identify a reasonable range of restoration 
    alternatives for consideration. Each alternative is comprised of 
    primary and/or compensatory restoration components that address one or 
    more specific injuries associated with the incident. Primary 
    restoration refers to any actions taken to return the injured natural 
    resources and services to baseline on an accelerated time frame. 
    Natural recovery, in which no human intervention is taken to accelerate 
    recovery of the injured natural resource and service, is included under 
    the primary restoration component. Compensatory restoration refers to 
    any actions taken to compensate for the interim losses of natural 
    resources and services, from the time of the incident until recovery is 
    achieved.
        Each alternative must be designed so that, as a package of one or 
    more actions, the alternative would satisfy OPA's goal to make the 
    environment and public whole for injuries resulting from an incident. 
    Only those alternatives considered technically feasible and in 
    accordance with applicable laws, regulations, or permits may be 
    considered further under this rule. Acceptable restoration alternatives 
    include any of the actions authorized under OPA (restoration, 
    rehabilitation, replacement, or acquisition of the equivalent), or any 
    combination of those actions.
    2. Primary Restoration
        Trustees must consider primary restoration actions, including a 
    natural recovery alternative. Alternative primary restoration actions 
    can range from natural recovery with no human intervention, to actions 
    that prevent interference with natural recovery, to more intensive 
    actions expected to return injured natural resources and services to 
    baseline faster or with greater certainty than natural recovery.
        When identifying primary restoration actions to be considered, 
    trustees should consider whether activities exist that would prevent or 
    limit the effectiveness of restoration actions (e.g., residual sources 
    of contamination). Trustees should also consider whether any primary 
    restoration actions are necessary to return the physical, chemical, and 
    biological conditions necessary to allow recovery or restoration of the 
    injured natural resources (e.g., replacement of sand or vegetation, or 
    modifying hydrologic conditions). Finally, trustees should consider 
    whether restoration actions focusing on certain natural resources and 
    services would be an effective approach to achieving baseline 
    conditions (e.g., replacing essential species, habitats, or public 
    services that would facilitate the replacement of other, dependent 
    natural resource and service components).
    3. Compensatory Restoration
        In addition to primary restoration, trustees must consider 
    compensatory restoration actions in some or all of the restoration 
    alternatives. The extent of interim natural resource or service losses 
    that must be addressed by a particular restoration alternative may vary 
    depending on the level and speed of recovery generated by the primary 
    restoration component of the restoration alternative.
        To the extent practicable, when identifying the compensatory 
    restoration components of the restoration alternatives, trustees should 
    consider compensatory restoration actions that provide services of the 
    same type and quality, and of comparable value as those injured. This 
    is the preferred approach to identifying compensatory restoration 
    actions. If such actions do not provide a reasonable range of 
    alternatives, trustees should identify actions that, in the judgment of 
    the trustees, will provide services of at least comparable type and 
    quality as those injured. Where the injured and replacement natural 
    resources and services are not of comparable value, the scaling process 
    will involve valuation of injured and replacement services.
        In general, both primary and compensatory restoration of services 
    must be accomplished through actions to restore natural resources or to 
    preserve or enhance the amount, quality, and/or availability of natural 
    resources that provide the same or similar services. This may include 
    actions to improve access to natural resources, although in selecting 
    such actions, the trustees must carefully evaluate the direct and 
    indirect impacts of the improved access on natural resource quality and 
    productivity. In the natural resource damages context, a service may 
    not be viewed as an abstract economic unit or activity that may be 
    restored independently of the natural resources from which the service 
    flows.
    4. Scaling Restoration Actions
        To ensure that a restoration action will appropriately address the 
    injuries resulting from an incident, trustees must scale the action. 
    For primary restoration, scaling as described in the rule 
    
    [[Page 453]]
    generally applies to acquisition and/or replacement actions, whereas 
    the amount of direct restoration or rehabilitation to undertake may be 
    determined based on such factors as area of habitat contaminated at 
    unacceptable levels, or the volume of removed sand that should be re-
    supplied. The approaches that may be used to assess the appropriate 
    scale of a restoration action to compensate for public losses include 
    resource-to-resource or service-to-service approaches, or valuation 
    approaches. Trustees should be careful to avoid double-counting, which 
    could result from developing multiple restoration actions that 
    compensate for ecological and direct human services losses over time. 
    For example, when determining the need for compensatory restoration 
    actions that directly address lost human services, trustees should take 
    into account any compensation for those lost human services provided by 
    other actions intended to compensate for lost ecological services.
    a. Resource-to-Resource and Service-to-Service Scaling Approaches
        Under the resource-to-resource and service-to-service approaches to 
    scaling, the appropriate quantity of replacement natural resources and/
    or services is determined by obtaining equivalency between the injured 
    and replacement natural resources and/or services, after appropriately 
    discounting for differences in the timing of the injury and the 
    replacement. Trustees must consider use of the resource-to-resource or 
    service-to-service approach for actions that provide natural resources 
    and/or services of the same type and quality, and comparable value to 
    those injured.
        Under the resource-to-resource or service-to-service approach, NOAA 
    recommends use of habitat equivalency analysis, or comparable 
    procedures, when injured natural resources and/or services are 
    primarily of indirect human use (e.g., species habitat or biological 
    natural resources for which human uses are primarily off-site). (See 
    Appendix B at the end of this preamble for a description of habitat 
    equivalency analysis.) If injured services are human uses (e.g., 
    recreational services), then a behavioral model of human use may be 
    used to determine the scale of the restoration action necessary to 
    provide the appropriate level of human uses. For example, if the 
    interim lost services are lost recreational beach days, then the 
    restoration action may be designed to provide the requisite number of 
    recreational beach days by, for example, improving access to existing 
    public beaches.
    b. Valuation Approach
        Where trustees have determined that resource-to-resource or 
    service-to-service scaling is not appropriate, trustees may use the 
    valuation approach to scaling. The valuation approach requires that 
    trustees determine the amount of natural resources and/or services that 
    must be provided to produce comparable value to the public as the loss 
    in public value resulting from the injuries. The approach relies on the 
    concept that lost value can be determined using one of a variety of 
    possible units of exchange, including units of natural resource 
    services or dollars. The valuation approach requires that the value of 
    injured natural resources and/or services be measured explicitly, and 
    that a restoration action provide natural resources and/or services of 
    equivalent value to the public. To properly scale a restoration action, 
    trustees might have to measure the values of varying sizes of the 
    restoration action to determine the size of an action that will replace 
    the value of injured natural resources and/or services. For proper 
    comparison, all values lost or provided over time should be converted 
    into present value terms by discounting.
        The valuation approach may be implemented with separate 
    calculations of losses and gains. A variety of valuation procedures is 
    available for this purpose, including the travel cost method, factor 
    income approach, hedonic price models, models of market supply and 
    demand, contingent valuation, and conjoint analysis. (See Appendix B at 
    the end of this preamble for descriptions of these procedures.)
        Where feasible, trustees should use the same or similar valuation 
    procedures for measuring the value of the injured services and the 
    value of the services provided by the restoration actions. Trustees 
    must ensure that bias is not introduced into the scaling calculations 
    via the separate calculations of losses and gains, particularly when 
    different valuation procedures are used.
        Alternatively, it may be possible to implement the valuation 
    approach with a single survey eliciting the direct resource-to-resource 
    trade-offs between the injured natural resources and potential 
    compensatory natural resources. Conjoint analysis, or contingent choice 
    analysis, may provide suitable procedures for these measurements.
        Trustees may use any reliable procedure suitable for scaling 
    compensatory restoration that meets the standards for acceptable 
    procedures in Sec. 990.27 of the rule. Where the circumstances are such 
    that a site-specific application of a valuation procedure does not meet 
    the reasonable cost criterion, the trustees may consider using benefits 
    transfer. The choice of approaches in a particular context will depend 
    upon the types of injuries and the type of services provided by the 
    restoration action.
        If valuation of the natural resources and/or services provided by a 
    compensatory restoration action could not, in the judgment of the 
    trustees, be performed within a reasonable time frame or at a 
    reasonable cost consistent with Sec. 990.27(a) of the rule, the 
    trustees may calculate the monetary value of the injured natural 
    resources and/or services, and then select the scale of a restoration 
    action that has a cost equivalent to the lost monetary value. However, 
    the responsible parties may request that trustees value the natural 
    resources and services provided by the restoration action, following 
    the process outlined in Sec. 990.14(c) of the rule.
    c. Treatment of Uncertainty and Discounting
        When scaling a restoration action, trustees should address the 
    uncertainties associated with the predicted consequences of both the 
    primary and compensatory restoration actions that will affect the level 
    and duration of losses from the injury and gains from the compensatory 
    restoration action. In addition, trustees must take account of the 
    value of time in the scaling calculations by discounting to the present 
    the interim lost services or the value of interim lost services due to 
    the injury, as well as the gain in services or service value from the 
    restoration action. The reference date for the discounting calculation 
    is the date at which the demand is presented.
        NOAA recommends that, where feasible, the trustees should use risk-
    adjusted measures of losses and gains, in conjunction with a riskless 
    rate of discount reflecting the social rate of time preference for 
    natural resources (i.e., the rate society is willing to substitute 
    between present and future consumption of natural resources with 
    certainty). Risk-adjusted measures of losses and gains take account of 
    the fact that people tend to be risk averse, and must be compensated 
    for bearing uncertainty. For example, it may be possible to compensate 
    for uncertainty in outcomes from compensatory restoration actions with 
    a larger scale action. Because of the difficulty in determining the 
    rate of time preference 
    
    [[Page 454]]
    for goods (such as natural resources) that are not generally sold in a 
    market, a real rate of three percent (3%) is recommended as a riskless 
    rate, unless justification is presented for a rate more appropriate for 
    the specific context. Alternatively, if the streams of losses and gains 
    cannot be adequately adjusted for risks, then NOAA recommends use of a 
    discount rate that incorporates a suitable risk adjustment to the 
    riskless rate.
        Existing economic literature suggests that three percent (3%) is a 
    reasonable choice for the social rate of time preference, given that it 
    is the middle of the range of values for the subjective rate of time 
    preference implied by long-run growth models of the U.S. economy. 
    Further, 3% is at the lower end of the range of the financial 
    opportunity costs of consumption, which are relatively low for 
    individuals who are net savers, and much higher for individuals who are 
    net borrowers. The long-term average real after tax rate of return on 
    3-month Treasury bills, a proxy for a riskless savings asset, is around 
    one percent (1%), though more recent rates are substantially higher 
    (around 2% during the 1983-1994 period). Consumer borrowing rates 
    depend upon the source of financing, but may exceed ten percent (10%) 
    in real terms for many credit cards. Because consumers' use of natural 
    resources does not occur primarily through market transactions, 
    consumers do not necessarily adjust their inter-temporal consumption of 
    natural resources in response to the relevant intertemporal financial 
    trade-offs available to them; nonetheless, the financial opportunity 
    costs provide an additional reference point.
        The analysis should be conducted in real terms (e.g., in units of 
    services, or in dollars of a specified base year). By definition, an 
    analysis conducted in units of natural resources or services is in real 
    terms. If the analysis is conducted in money value terms, then all 
    money values should be specified in terms of the dollars of a specified 
    base year. To adjust the measures of monetary losses or gains to 
    dollars of the specified base year, the Consumer Price Index is most 
    appropriate when the measure of losses is consumer surplus. 
    Alternatively, for more generalized measures of losses or for future 
    projections of inflation, trustees may use the Gross Domestic Product 
    price index, for which the Administration predicts a time-series of 
    future deflators every year. Sources of information for discounting are 
    identified in the preamble discussion of discounting in the 
    Implementation Phase.
    C. Evaluation of Restoration Alternatives
    1. General
        Once trustees have developed a reasonable range of restoration 
    alternatives, they must evaluate those alternatives. This evaluation is 
    based, at a minimum, on:
        (i) The cost to carry out the alternative;
        (ii) The extent to which each alternative is expected to meet the 
    trustees' goals and objectives in returning the injured natural 
    resources and services to baseline and/or compensate for interim 
    losses;
        (iii) The likelihood of success of each alternative;
        (iv) The extent to which each alternative will prevent future 
    injury as a result of the incident, and avoid collateral injury as a 
    result of implementing the alternative;
        (v) The extent to which each alternative benefits more than one 
    natural resource and/or service; and
        (vi) The effect of each alternative on public health and safety.
        Based on an evaluation of these factors, trustees must select a 
    preferred restoration alternative(s). If the trustees conclude that two 
    or more alternatives are equivalent based on the above factors, the 
    trustees must select the most cost-effective alternative.
        When selecting a restoration alternative, trustees should consider 
    the relationship between costs and benefits. However, reducing the 
    selection process to a strict comparison of restoration costs to 
    monetized natural resource values is not required and may not be 
    appropriate. Instead, the rule requires trustees to evaluate each 
    alternative according to the factors listed above and identify a 
    preferred alternative. NOAA believes this approach provides adequate 
    protection against selection of an inappropriately costly alternative.
    2. Pilot Restoration Projects
        If the range of restoration alternatives under consideration is 
    limited or poorly developed, or if a promising restoration action 
    cannot be adequately evaluated without testing, trustees may implement 
    pilot projects. Pilot projects should only be undertaken when, in the 
    judgment of the trustees, these projects are likely to successfully 
    provide information for the evaluation factors specified above at a 
    reasonable cost and in a reasonable time frame. Examples of situations 
    where pilot projects may be appropriate include application of a proven 
    technology in a different habitat type, or using different species than 
    those used in previous applications.
    D. Restoration Plans
    1. Purpose
        After selecting a restoration alternative, trustees must prepare a 
    Draft Restoration Plan. Development of a Draft Restoration Plan 
    provides a vehicle for informing the affected and interested public of 
    the results of the trustees' analyses and decisions, and encouraging 
    public review. Public review can also supplement expert peer review 
    when comments are solicited from various professional communities or 
    other knowledgeable persons.
    2. Draft Restoration Plan
        A Draft Restoration Plan must include:
        (i) A summary of injury assessment procedures used;
        (ii) A description of the nature, degree, and spatial and temporal 
    extent of injuries resulting from the incident;
        (iii) The goals and objectives of restoration;
        (iv) The range of restoration alternatives considered, and a 
    discussion of how such alternatives were developed and evaluated under 
    this rule;
        (v) Identification of the trustees' tentative preferred 
    alternative(s);
        (vi) A description of past and proposed involvement of the 
    responsible parties in the assessment; and
        (vii) A description of monitoring for documenting restoration 
    effectiveness, including performance criteria that will be used to 
    determine the success of restoration and need for interim corrective 
    action.
        When developing the Draft Restoration Plan, trustees must clearly 
    define plan objectives that specify the desired outcome to be 
    accomplished, and the performance criteria by which successful 
    restoration will be judged. Trustees must, at a minimum, determine what 
    criteria will constitute success such that responsible parties are 
    relieved of responsibility for further restoration actions or 
    necessitate corrective actions in order to comply with the terms of a 
    restoration or settlement agreement.
        Performance criteria include structural, functional, temporal, and/
    or other demonstrable goals that the trustees should determine with 
    respect to all restoration actions. For example, an agreement to create 
    new intertidal marsh habitat as compensation for a marsh injured by oil 
    could be described by performance criteria including the number of 
    acres to be created, location, elevation of new habitat, species to be 
    planted and details for planting such as 
    
    [[Page 455]]
    density, and time frame in which identifiable stages of the restoration 
    action should be completed.
        The types of parameters that should be addressed in monitoring 
    include duration and frequency of monitoring needed to gauge progress 
    and success, the level of sampling needed to detect success or the need 
    for corrective action, and whether monitoring of a reference or control 
    site is needed to determine progress and success. Reasonable monitoring 
    and oversight costs cover those activities necessary to gauge the 
    progress, performance, and success of the restoration actions developed 
    under the plan.
    3. Public Review and Comment
        Public review and comment of both Draft and Final Restoration Plans 
    will depend on the nature of the incident and any applicable federal 
    trustee NEPA requirements, as described in Secs. 990.14(d) and 990.23 
    of the rule, but must be sufficient to satisfy OPA's requirement for 
    public involvement in planning restoration. Thus, trustees should 
    consider such factors as the form of the involvement (e.g., a hearing, 
    notice, or solicited comments), extent of public involvement (e.g., 
    timing and frequency), and the forum for communicating with the public 
    (e.g., local papers, the Federal Register, direct contacts to known 
    interested parties).
    4. Final Restoration Plan
        After reviewing public comments on the Draft Restoration Plan, 
    trustees must develop a Final Restoration Plan. As part of the Final 
    Restoration Plan, trustees must consider comments on the Draft 
    Restoration Plan. In response to the comments, the trustees may need to 
    modify the restoration alternatives being considered, develop and 
    evaluate alternatives that have not been given serious consideration by 
    the trustees, supplement, improve, or modify the analyses, make factual 
    corrections, or explain why the comments do not warrant further trustee 
    response, citing the reasons to support the trustee position, and 
    possibly indicate the circumstances that would trigger reappraisal or 
    further response.
        In the Final Restoration Plan, trustees indicate the restoration 
    alternatives that will be implemented and include the information in 
    the Draft Restoration Plan. The format of the Final Restoration Plan, 
    which essentially follows that of the Draft Restoration Plan, should 
    clearly indicate all significant changes to the Draft Restoration Plan.
    E. Use of a Regional Restoration Plan or Existing Restoration Project
        The rule allows trustees to consider all or part of an existing 
    Regional Restoration Plan or other existing, planned, or proposed 
    environmental restoration project as one of the range of restoration 
    alternatives, including natural recovery, evaluated to restore injuries 
    resulting from a particular incident. Like any other restoration 
    alternative considered, Regional Restoration Plans and existing 
    restoration projects must be consistent with OPA's requirement that 
    damages recovered be used solely to restore, replace, rehabilitate, or 
    acquire the equivalent of injured natural resources and/or services. 
    Regional Restoration Plans or other existing restoration projects meet 
    this requirement if the plan or project will return injured natural 
    resources and/or services to baseline and/or compensate for interim 
    losses. Use of an existing plan or project may be considered as either 
    a primary or compensatory restoration action under the rule, depending 
    on the circumstances of the incident, injuries, and natural resources 
    or services provided by the plan or project.
        Under the rule, selection of an existing plan or project as the 
    preferred restoration alternative requires that the plan or project had 
    been developed with public review and comment, or is subject to public 
    review and comment in accordance with the rule. The existing plan or 
    project must also be demonstrated to provide a sufficient link to the 
    incident in terms of the type and scale of natural resources and 
    services provided by the plan or project.
        The rule also allows trustees to recover partial funding of 
    existing plans or projects from responsible parties, where a plan or 
    project that represents the preferred primary or compensatory 
    restoration for an incident will provide significantly greater levels 
    of natural resources and/or services than those lost as a result of the 
    incident. In these instances, trustees may request the scale of the 
    restoration determined to be appropriate for the incident of concern. 
    Trustees may pool such partial recoveries until adequate funding is 
    available to implement the existing plan or project. Trustees must make 
    diligent efforts to ensure that the selected project is implemented in 
    a reasonable time following initial recovery of partial funding.
    
    Subpart F--Restoration Implementation Phase
    
    I. Introduction
    
        After the completion of the Restoration Planning Phase, the 
    trustees must: (i) close the administrative record that incorporates 
    the Restoration Planning Phase and open a new administrative record for 
    the Restoration Implementation Phase; (ii) present a demand for 
    implementation or for damages to the responsible parties; (iii) 
    establish an account to receive any payments from the responsible 
    parties; and (iv) implement restoration. Additional actions that could 
    occur during the Restoration Implementation Phase include filing an 
    action for damages where the responsible parties refuse to implement or 
    pay for restoration on receipt of the trustees' demand, or seeking an 
    appropriation from to the Oil Spill Liability Trust Fund, so that 
    restoration can be implemented.
    
    II. Administrative Record
    
        Within a reasonable time after completing restoration planning 
    under subpart E of the rule, the administrative record of the 
    Restoration Planning Phase must be closed. Except as noted below, no 
    additional documents will be placed in the record. The closed record 
    will constitute the body of information supporting the trustees' 
    decisions through restoration planning.
        Once the record is closed, trustees may, as a general matter, only 
    add documents that:
        (i) Are offered by any interested party that did not receive actual 
    or constructive notice of the Draft Restoration Plan and the 
    opportunity to comment on the Plan;
        (ii) Do not duplicate information already contained in the 
    administrative record; and
        (iii) Raise significant issues regarding the Final Restoration 
    Plan.
        For practical reasons, it is likely that trustees will need to open 
    and maintain an additional administrative record to document 
    implementation of restoration. This record should document, at a 
    minimum, all Restoration Implementation Phase decisions, actions, and 
    expenditures, including any modifications made to the Final Restoration 
    Plan. This record is necessary to keep the public informed and for 
    potential use in any enforcement actions, such as seeking additional 
    work from the responsible parties to comply with the restoration plan 
    and implementing agreements. The record will also ensure an accurate 
    and complete accounting of all actions and 
    
    [[Page 456]]
    costs associated with implementing the Final Restoration Plan.
        The administrative record for restoration implementation should 
    follow the same guidance for opening and maintaining the previous 
    record, and for its availability as discussed in Sec. 990.45 of the 
    rule. The costs of maintaining the administrative record and making it 
    available to the public are part of the costs of restoration.
    
    III. Presenting a Demand for Damages to the Responsible Parties
    
        If the trustees and responsible parties have successfully 
    implemented cooperative restoration planning, the responsible parties 
    will have thorough knowledge of the trustees' preferred restoration 
    alternative(s) and associated costs. In the best circumstances, the 
    responsible parties will already have entered into an enforceable 
    agreement to either pay assessment costs and the costs associated with 
    implementing the Final Restoration Plan, or to implement the Plan 
    according to trustee performance criteria and with trustee oversight 
    and reimburse trustees for assessment and oversight costs. Any such 
    existing agreements with the responsible parties should be described in 
    the Draft and Final Restoration Plans.
        However, where such an agreement with responsible parties has not 
    been achieved, the trustees must follow some specific statutory 
    requirements to recover natural resource damages, as described below.
        After completion of restoration planning under subpart E of the 
    rule, the trustees must present a demand in writing asking the 
    responsible parties either to:
        (i) Implement the Final Restoration Plan or component of a Regional 
    Restoration Plan or existing restoration project, subject to trustee 
    oversight, and reimburse the trustees for their assessment and 
    oversight costs; or
        (ii) Advance to the trustees a specified sum representing 
    assessment costs and the trustees' estimate of all direct and indirect 
    costs associated with developing and implementing the Final Restoration 
    Plan or some component of a Regional Restoration Plan or an existing 
    restoration project, discounted as provided in Sec. 990.63 of the rule.
        When the trustees use a Regional Restoration Plan, as provided in 
    Sec. 990.56 of the rule, the demand will invite the responsible parties 
    to implement a component of a Regional Restoration Plan or existing 
    restoration project or advance the trustees' estimate of damages based 
    on the scale of the restoration determined to be appropriate for the 
    incident of concern. To avoid litigation, the responsible parties must 
    respond within ninety (90) calendar days in writing by paying or 
    providing binding assurance they will reimburse trustees' assessment 
    costs and implement the plan or pay assessment costs and the trustees' 
    estimate of the costs of implementation.
        The demand must also include: identification of the incident from 
    which the claim arises; identification of the trustees asserting the 
    claim and a statement of the statutory basis for their trusteeship; a 
    brief description of the injuries for which the claim is being brought; 
    the index to the administrative record; the Final Restoration Plan or 
    Notice of Intent to Use a Regional Restoration Plan or Existing 
    Restoration Project; and a request for reimbursement of reasonable 
    assessment costs, as defined in Sec. 990.30 of the rule and discounted 
    as provided in Sec. 990.63(b) of the rule; the cost, if any, of 
    conducting emergency restoration under Sec. 990.26 of the rule, 
    discounted as provided in Sec. 990.63(b) of the rule; and interest on 
    the amounts recoverable, as provided in section 1005 of OPA (33 U.S.C. 
    2705), which allows for prejudgment and post-judgment interest to be 
    paid at a commercial paper rate, starting from thirty (30) calendar 
    days from the date a demand is presented until the date the claim is 
    paid.
    
    IV. Discounting and Compounding Components of the Claim
    
    A. General
        Discounting is necessary for the trustees to be able to present a 
    claim for a ``sum certain,'' as required by section 1001(3) of OPA (33 
    U.S.C. 2701(3)). The reference date for the discounting calculations is 
    the date at which the demand is presented. Trustees must discount 
    future restoration costs back to the present and compound assessment 
    and emergency restoration costs already incurred forward to the 
    present. The use of discounting in scaling restoration actions is 
    discussed separately in subpart E of the rule.
        NOAA recommends that trustees use the U.S. Treasury borrowing rate 
    on marketable securities of comparable maturity to the period of 
    analysis for both calculations, with some qualifications noted below. 
    Alternatively, for state or tribal claims for past damage assessment 
    and restoration costs, the state or Indian tribe may use the state or 
    tribal borrowing rate on marketable securities. The analysis should be 
    conducted either in terms of nominal values (denominated in dollars of 
    the year in which the losses or gains are incurred) or in constant 
    dollars of a specified base year. For compounding past emergency 
    restoration and assessment costs, trustees should use U.S. Treasury 
    rate as the discount rate and represent the costs in nominal terms, 
    since the nominal interest is observed and past costs are likely to be 
    denominated in nominal terms. Anticipated inflation can be incorporated 
    in estimates of future restoration costs with an appropriate inflation 
    index.
    B. Estimated Future Restoration Costs
        Most restoration actions will be carried out over a period of 
    years. If funds are insufficient to cover the full costs of 
    restoration, including post-implementation maintenance and monitoring 
    operations, natural resource and service recovery will be incomplete, 
    and the public will be deprived of full compensation for the injuries. 
    NOAA recommends that, for discounting future restoration costs, 
    trustees specify future restoration costs in nominal terms (i.e., in 
    terms of dollars of the year in which the costs will be incurred) and 
    then discount the nominal costs using the nominal U.S. Treasury rate 
    for marketable securities of comparable maturity to the period of 
    analysis, when this rate of return is available to the trustees for 
    investment of settlement monies. To specify the future restoration 
    costs in nominal terms, the trustees should employ the indices of 
    projected inflation appropriate to the major components of the 
    restoration costs (e.g., construction price indices for construction 
    costs; the federal employee wage index for trustee monitoring costs). 
    If component-specific inflation indices are unavailable, the Gross 
    Domestic Product price index may be used.
        If legal and/or institutional constraints prevent investment of 
    settlement monies yielding the U.S. Treasury rate for marketable 
    securities of comparable maturity to the period of analysis, trustees 
    should structure the claim to ensure that sufficient funds will be 
    available to fund the entire selected restoration alternative. One 
    option is to calculate the discounted value of this component of the 
    claim using an alternative discount rate that represents the yield on 
    settlement monies available to the trustees. An alternative option is 
    to structure a multi-year schedule for claim payments to ensure it 
    provides the cash flow for each year required for planned expenditures.
        If the settlement is structured so that the responsible parties 
    carry out the restoration actions, the trustee restoration costs to be 
    discounted will be substantially reduced, but they will 
    
    [[Page 457]]
    not be eliminated because trustee monitoring and oversight costs will 
    still be included in the claim.
    C. Past Assessment and Emergency Restoration Costs
        Past assessment and emergency restoration costs may accrue from the 
    time of the incident to the date of the demand. To calculate the 
    present value of these costs at the time the demand is presented to the 
    responsible parties, the trustees will compound forward the costs 
    already incurred. Because the rate of interest employed as the compound 
    rate for past costs incurred should reflect the opportunity cost of the 
    money spent, NOAA recommends that the trustees use the actual U.S. 
    Treasury rate for marketable securities of comparable maturity to the 
    period of analysis for discounting this component of the claim. NOAA 
    acknowledges that, at the discretion of the trustees, a state or tribal 
    borrowing rate may be used to compound the state or tribal component of 
    past costs. Where the costs are denominated in dollars of the year in 
    which they were incurred (i.e., in nominal terms), the nominal interest 
    rate should be employed.
    D. Sources of Data
        U.S. Treasury bill and bond rates may be found in the Federal 
    Reserve Bulletin, issued monthly, or the Treasury Bulletin, issued 
    quarterly. The Gross Domestic Product fixed-weighted price index and 
    the Consumer Price Index may be found in the Survey of Current 
    Business, issued monthly, and the Economic Report of the President, 
    issued annually. The Administration prediction for future Gross 
    Domestic Product deflators is updated twice annually at the time the 
    budget is published in January or February and at the time of the Mid-
    Session Review of the Budget in July. The current Treasury rates and 
    inflation adjustment assumptions, as well as guidance in calculation 
    procedures, are reported in regular updates of Appendix C of Circular 
    No. A-94, available from the OMB Publications Office (202-395-7332).
    
    V. Unsatisfied Demands
    
        If the responsible parties deny all liability for the claim or fail 
    to settle the claim embodied in the demand within ninety (90) calendar 
    days after they are presented with the demand, trustees may elect to 
    commence an action in court against the responsible parties or 
    guarantors, or to seek an appropriation from the Oil Spill Liability 
    Trust Fund. Thus, delivery of the demand should be made in a manner 
    that establishes the date of receipt by the responsible parties.
        Judicial actions and claims must be filed within three (3) years 
    after the Final Restoration Plan or Notice of Intent To Use a Regional 
    Restoration Plan or Existing Restoration Project is made publicly 
    available, in accordance with the statute of limitations for natural 
    resource damages under OPA (33 U.S.C. 2717(f)(1)(B) and 2712(h)(2)).
    
    VI. Opening an Account for Recovered Damages
    
        Section 1006(f) of OPA (33 U.S.C. 2706(f)) requires that sums 
    recovered by trustees in satisfaction of a natural resource damage 
    claim be retained, without further appropriation, in a revolving trust 
    account. Sums recovered for past assessment costs and emergency 
    restoration costs may be used to reimburse the trustees. All other sums 
    must be used to implement the Final Restoration Plan, implement all or 
    an appropriate component of a Regional Restoration Plan or existing 
    restoration project.
        Where multiple trustees are involved in a recovery, trustees may 
    wish to establish a joint account. One acceptable mechanism would be an 
    account under the registry of the applicable federal court when there 
    is a joint recovery involving federal and non-federal trustees. The 
    joint account should be managed by the trustees through an enforceable 
    written agreement that specifies the parties authorized to endorse 
    expenditures out of the account, and the agreed-upon procedures and 
    criteria for such expenditures.
        Although a joint account may be the preferred approach, trustees 
    also have the option of dividing the recoveries and depositing their 
    respective amounts in their own separate accounts, if such action would 
    be consistent with the terms and objectives of the restoration plan. 
    These accounts should be interest-bearing, revolving trust accounts.
        Trustees may establish escrow accounts or any other investment 
    accounts, if otherwise authorized by law. Funds in such accounts must 
    only be used as specified in section 1006(f) of OPA (33 U.S.C. 
    2703(f)).
        Trustees must maintain appropriate accounting and reporting 
    procedures to keep track of the use of sums recovered. Brief reports on 
    the status of the sums recovered and expenditures for particular 
    incidents should be made part of the administrative record for the 
    Restoration Implementation Phase.
        Any sums remaining in an account established under this section 
    that are not used either to reimburse trustees for past assessment and 
    emergency restoration costs or to implement restoration must be 
    deposited in the Oil Spill Liability Trust Fund, as provided in section 
    1006(f) of OPA (33 U.S.C. 2706(f)).
    
    VII. Additional Considerations
    
    A. General
        As discussed throughout the rule, the Final Restoration Plan may be 
    implemented by the trustees, or by the responsible parties with trustee 
    oversight. In either case, several common steps may characterize the 
    Restoration Implementation Phase, including establishment of a trustee 
    committee and/or Memoranda of Understanding, development of more 
    detailed workplans for the conduct of restoration actions, monitoring 
    and oversight, and evaluation of restoration success or need for 
    corrective actions.
    B. Trustee Committee and/or Memorandum of Understanding
        In many instances, it is likely that a trustee committee and/or a 
    Memorandum of Understanding or other agreements will have governed 
    trustee involvement through the Restoration Planning Phase. However, it 
    is critical that these agreements extend through the Restoration 
    Implementation Phase, or that new agreements or committees are formed 
    for the restoration implementation. At a minimum, representatives of 
    each participating trustee agency should be appointed to an oversight 
    committee. Functions of such a committee may include authorizing 
    expenditures from a joint account, participating in monitoring and 
    oversight of restoration actions, evaluating performance criteria for 
    restoration actions, and making the determination that the goals and 
    objectives of the Final Restoration Plan have been achieved or 
    determining the type of corrective actions that need to be pursued, and 
    ensuring that these actions are implemented.
    C. Detailed Workplans
        Depending on the incident and the restoration alternative(s), 
    detailed workplans for accomplishing restoration goals and objectives 
    may have been developed during the Restoration Planning Phase. Clearly, 
    as many details outlining the restoration expectations, performance 
    criteria, timelines, criteria for success, etc., should be included in 
    the Final Restoration Plan and in agreements with the responsible 
    parties as are practicable to determine prior to presenting the demand 
    or settling a claim. 
    
    [[Page 458]]
    
    D. Monitoring and Oversight
        Reasonable monitoring and oversight costs are included in 
    recoverable damages. A well-designed and executed monitoring and 
    oversight plan is required to assess progress toward the stated goals 
    and objectives of a restoration plan. Reasonable monitoring and 
    oversight costs are limited to those costs necessary to determine 
    restoration success, or the need for, type of, and scale of corrective 
    actions. Monitoring should be designed around performance criteria that 
    will indicate success of restoration.
    E. Restoration Success and Corrective Actions
        Restoration plans, particularly those including agreements for 
    responsible parties to implement restoration, must identify criteria 
    against which success and completion of restoration actions will be 
    judged.
        In some cases, pilot projects will lessen the need for corrective 
    measures. In other cases, settlement agreements can include reopeners 
    to deal with specific points of uncertainty, for instance, for 
    significant injuries that could not be determined and/or quantified at 
    the time of a settlement. Another possibility is for the responsible 
    parties to deposit an agreed-upon amount of money in an escrow account 
    to cover future contingencies that could not be fully anticipated at 
    the time of the settlement. These funds would then be used for future 
    actions, or revert to the responsible parties if not needed. In most 
    cases, trustees should consider including a mechanism to deliberate the 
    need for and type of corrective actions in a settlement agreement where 
    the types of contingencies that suggest the need for corrective actions 
    cannot be completely foreseen.
        In all cases, the type and scale of corrective actions must be 
    determined relative to the restoration goals and objectives set out in 
    the Final Restoration Plan. In addition, trustees must recognize that 
    circumstances well beyond the control of any of the parties may not be 
    the basis of requiring corrective actions, such as natural occurrences 
    that would meet an ``Act of God'' standard.
    
    TREATMENT OF COMMENTS
    
    Extension of Comment Period
    
        Comment: Several commenters requested a 60-day extension in the 
    public comment period. These commenters stated that an extension was 
    required to strike the proper balance between the time allotted for the 
    public's review and comment, and the time needed for a thorough 
    analysis of comments on the proposed rule. According to some 
    commenters, the public's interest in having an adequate opportunity to 
    review and comment on regulatory initiatives under the Administrative 
    Procedure Act (5 U.S.C. 551-59, 701-06) should not be compromised by 
    the establishment of arbitrary deadlines. One commenter requested that 
    the comment period be extended for at least 60 days after the last of 
    the guidance documents is made available for public review, as a 
    thorough understanding and review of the guidance documents are 
    essential to adequately present comments on the proposed rule.
        Response: NOAA has made every effort to consider all comments 
    submitted on the 1994 proposal, the August 3, 1995, proposed rule, and 
    comments expressed during the conferences held in August and September 
    of 1995. NOAA believes that the rule describes the assessment process 
    in sufficient detail, including listing of decision points, 
    determinations, decision criteria, and standards for selection of 
    procedures such that the guidance documents are truly complementary, 
    and not required to understand how to plan assessments in accordance 
    with this rule.
    
    Subpart A
    
    Section 990.10--Purpose
    
        Comment: Many commenters supported the scope and direction of the 
    new proposal. Some of these commenters specifically noted that the 
    focus on restoration is a positive change. One of these commenters 
    stated that this approach will provide increased flexibility and 
    improve cooperation among trustees and responsible parties in achieving 
    restoration. Other commenters noted that this proposal is simpler and 
    more straightforward. Several of these commenters in particular 
    supported the move away from the use of claims based upon monetization 
    of natural resource values.
        Response: NOAA notes and appreciates the support from the 
    commenters for the scope and direction of the rule.
        Comment: While supportive of the new direction of the rule, one 
    commenter pointed out that, as a federal agency, NOAA should recognize 
    its fiduciary duty to Indian tribes and tribal natural resources, and 
    take care not to impinge upon the ability of the tribes to recover 
    damages.
        Response: NOAA believes the rule's restoration focus will better 
    facilitate recovery of damages, while still allowing trustees, 
    including tribes, the discretion to apply whatever assessment approach 
    is most appropriate to the particular natural resources and services 
    injured by a given incident.
        Comment: Another commenter suggested that NOAA should consider 
    reserving troublesome sections of the rule for future development, 
    perhaps through one or more Federal Advisory Committee Act (5 U.S.C. 
    App. 2) groups.
        Response: NOAA does not believe that any provisions of the rule are 
    so wholly problematic to warrant the treatment suggested by the 
    reviewer. NOAA believes that the process embodied in the rule will 
    facilitate development of appropriate solutions to some questions that 
    can only be answered on an incident-by-incident basis.
        Comment: One commenter stated that the new approach is an untried 
    theory, thus it is unclear whether this approach would be better or 
    worse than the approach under the CERCLA rule. Another commenter 
    suggested that the provisions in the proposed rule are vague, that 
    critical terms are undefined, and insufficient guidance is provided for 
    implementation of the approach. Another commenter noted that the 
    proposed rule fell short of providing trustees with a balance of 
    discretion and constraint needed to apply the still-developing science 
    of natural resource damage assessment within the dictates of the law.
        Response: NOAA notes that the approach embodied in the rule is far 
    from untried, rather it embodies the approaches taken in some of the 
    most successful cooperative settlements reached to date. Trustees, 
    responsible parties, and interested members of the public must be 
    afforded the ability to respond to injuries resulting from incidents 
    that can vary greatly from incident-to-incident; in this respect, 
    natural resource damage assessment will never be a static field. NOAA 
    has defined more terms in the final rule. The rule provides technical 
    and legal boundaries within which assessments must fall to be in 
    compliance with OPA. For instance, restoration must be necessary and 
    linked to the injuries from an incident under the rule. Finally, 
    assessment procedures must be technically appropriate for the 
    circumstances of an incident while providing information of use in 
    determining restoration needs.
        Comment: Some commenters argued that the excessive and arbitrary 
    assessments anticipated, given the rule's unlimited grant of discretion 
    to trustees, will result in unnecessary financial 
    
    [[Page 459]]
    burdens that cannot be borne by the maritime industries. Some 
    commenters suggested that the effect of the rule will be to rid from 
    U.S. waters all forms of water craft, as well as to freeze businesses 
    potentially liable under the rule. Another commenter suggested that the 
    potential large recoveries allowed by the rule could threaten the 
    ability of private individuals and businesses who suffer quantifiable 
    economic losses as a result of incidents to obtain full and fair 
    compensation for their losses.
        In contrast, several commenters argued that the new proposal is 
    significantly weaker than the 1994 proposal, with no justification 
    except industry pressure for an untested restoration-based approach 
    instead of the well-tested and supported economic valuation procedures. 
    The commenters suggested that this approach will lead to greater delays 
    in prosecuting and settling cases and that, to conform with the intent 
    of Congress, the rule must allow trustees greater discretion in 
    choosing assessment procedures or restoration options.
        Response: The intent of the rule is solely to ensure that natural 
    resources and their services that are injured, destroyed, or lost as a 
    result of an incident will be restored where there is a need to do so, 
    and where feasible and cost-effective means to accomplish restoration 
    are available. The rule's focus on restoration will eliminate unneeded 
    assessment studies and prevent unnecessary adversarial conflicts over 
    misunderstood goals of trustees. This rule invites responsible parties 
    to act cooperatively and responsibly to seek expeditious and cost-
    effective restoration, while clearly constraining trustees' actions to 
    those necessary to achieve OPA's restoration goals. Thus, costs and 
    damages will not be excessive or unpredictable. The rule has no 
    relation to private party claims that may be brought against 
    responsible parties under OPA, but the cost savings expected under the 
    rule from cooperation alone should alleviate fears that some third 
    parties will go uncompensated. In any event, uncompensated third party 
    claims may be presented to the Oil Spill Liability Trust Fund.
    
    Section 990.11--Scope
    
        Comment: One commenter requested that the rule clarify that its 
    provisions apply only to assessments being conducted under this rule, 
    not other causes of actions, for example causes under federal admiralty 
    or maritime law.
        Response: NOAA has explicitly stated in the rule that the various 
    provisions of this rule would apply only to assessments being conducted 
    under this rule for purposes of bringing a natural resource damages 
    claim pursuant to OPA and thus do not affect claims brought under other 
    authorities.
        Comment: One commenter stated that the rule should provide guidance 
    on how to distinguish trustee claims on behalf of the public from 
    private causes of action, particularly when natural resource injuries 
    are caused indirectly by an incident on private property.
        Response: It is not possible for NOAA to describe all instances 
    where trustee and private party claims may appear to be duplicative. 
    NOAA notes that the rule requires that trustees determine their 
    jurisdiction to proceed under the rule, which includes a determination 
    that the trustees have relevant responsibility over natural resources, 
    as defined under OPA, that are expected to be injured by an incident. 
    However, the preamble now includes guidance in the discussion of 
    Sec. 990.22 for trustees to avoid double recovery of damages with 
    private parties.
        Comment: A number of commenters remarked on NOAA's inconsistent 
    reference to what may be assessed and what may be restored under the 
    rule, by interchangeably using the terms ``natural resources and/or 
    services,'' and ``natural resources or services.'' Similarly, the 
    commenters suggested that the proposed rule inconsistently referred to 
    OPA's goal as making the ``environment and public whole,'' or simply 
    making ``the public whole.''
        Response: The rule has been clarified to reflect OPA's intent to 
    make the environment and public whole for injuries resulting from an 
    incident. This intent is clear in OPA's reference to natural resources 
    themselves as the focus of restoration, and in the distinction between 
    restoration costs and diminution in value as elements of a claim for 
    damages. Complete and expeditious restoration may be the best way to 
    make both the environment and public whole.
    
    Section 990.13--Effect of Rule
    
        Comment: One commenter questioned why, if a foreign entity is a 
    trustee under OPA, such entity cannot receive the rebuttable 
    presumption.
        Response: OPA does not, by its terms in section 1006(c)(1) (33 
    U.S.C. 2706(c)(1), grant the rebuttable presumption to foreign 
    trustees.
        Comment: Some commenters noted that the preamble description of the 
    meaning of the rebuttable presumption, i.e., that the responsible party 
    has the burden of proving that the trustees' claim and determinations 
    are incorrect, is wrong. Instead, the commenters stated that the 
    rebuttable presumption is overcome when the preponderance of the 
    evidence indicates a different result. Similarly, other commenters 
    argued that section 1006(e)(2) of OPA (33 U.S.C. 2706(e)(2)) describes 
    the rebuttable presumption as applying only to the determination or 
    assessment of damages, therefore it is only the final amount of 
    damages, not the particular steps taken to reach that result that 
    receive the rebuttable presumption.
        Response: NOAA has revised the rule to incorporate the statutory 
    language describing the provision of a rebuttable presumption for 
    assessments. In response to the comment regarding the meaning of such a 
    provision, NOAA interprets this presumption to mean that the 
    responsible parties have the burdens of presenting alternative evidence 
    on damages and of persuading the fact finder that the damage assessment 
    presented by the trustee(s) is not an appropriate measure of damages.
        Comment: Several commenters expressed strong support for the 
    provision found in Sec. 990.20(b) of the proposed rule extending the 
    rebuttable presumption to state, local, and tribal assessment 
    procedures. Some of these commenters noted that this will promote 
    consistency by providing an incentive for the development and use of 
    state and tribal procedures that are consistent with the federal 
    approach, thus benefiting responsible parties who deal with trustees 
    from different regions of the country. One commenter noted that the 
    five listed requirements for consistency with the proposed OPA rule are 
    straightforward and should aid state, local, and tribal trustees in 
    efficient implementation of the rule. Other commenters supported the 
    provision, but suggested that the rule explicitly include compensation 
    schedules, models, and procedures that estimate expected injuries in 
    the language of this section. One commenter was concerned that it is 
    unrealistic to expect any given procedure will not conflict in some way 
    with the proposed OPA rule.
        In contrast, several other commenters strongly objected to 
    extending the rebuttable presumption to state, local, or tribal 
    assessment procedures as being contrary to OPA. These commenters stated 
    that the criteria provided in the rule are far too general to 
    constitute substantive standards for the performance of assessments. 
    The commenters argued that NOAA has no authority to define the scope of 
    the rebuttable presumption since it is not a regulatory issue 
    implicating the assessment of damages, but is within the exclusive 
    province of the federal courts 
    
    [[Page 460]]
    to address. The commenters stated that Congress intended the rebuttable 
    presumption to attach only to assessments performed under section 
    1006(d) of OPA (33 U.S.C. 2706(d)), and only according to substantive 
    standards promulgated by NOAA, and that NOAA may not delegate this 
    authority. One other commenter argued that it would be unfair to allow 
    the rebuttable presumption for the plethora of assessment procedures 
    now available.
        Response: NOAA has revised Sec. 900.20 of the rule and removed the 
    explicit reference to state, local or tribal assessment procedures. 
    NOAA agrees that determining the scope of application of the rebuttable 
    presumption is not a necessary task in promulgating this rule. However, 
    NOAA notes that existing procedures that may be applicable to assessing 
    natural resource injuries and restoration needs may be used for 
    assessments under this rule, regardless whether those procedures were 
    promulgated under state laws respecting natural resource damage 
    assessment, developed through private scientific research, or developed 
    or adapted by the parties assessing the injuries of a particular 
    incident. It is not feasible to identify all assessment procedures, nor 
    the varied ways of applying such procedures, that will constitute 
    reliable and valid technical application for all potential incidents. 
    Thus, this rule specifies standards, in Sec. 990.27, that must be met 
    in order for any particular procedure to be used and deemed in 
    accordance with this part.
        Comment: One commenter stated that the rule does not provide 
    sufficient guidance to determine whether trustees' discretionary 
    actions are cost-effective, technically feasible, or in accordance with 
    generally accepted scientific practices. Therefore, assessments 
    conducted pursuant to this rule should not be granted a rebuttable 
    presumption. Another commenter, also arguing that it would be unfair to 
    grant a presumption to procedures that are speculative and unproven, 
    suggested that implementation of the rebuttable presumption be delayed 
    until there is more experience with restoration and valuation 
    procedures.
        Response: NOAA believes that the rule does provide the appropriate 
    constraints and standards for fashioning assessments that will be 
    technically sound, cost-effective, and reliable. The assessment focuses 
    on determining only the types and amounts of restoration required given 
    the particular injuries resulting from individual incidents. A 
    requirement to use ``generally accepted scientific practices'' would 
    result in overly-costly assessments in most instances, as the goals of 
    research science may be different than the goals of science for 
    purposes of natural resource damage assessment and restoration. 
    Finally, procedures cannot be deemed to be reliable or unreliable out 
    of context; the merits of different procedures will vary depending on 
    how they are proposed to be used in a given incident scenario. This 
    judgment will be made by trustees, in an open record atmosphere, with 
    input from responsible parties and the public.
    Use of Other Assessment Procedures, and the Scope of the Rebuttable 
    Presumption
        Comment: Several commenters took issue with the provision in the 
    proposed rule that allowed the rebuttable presumption to apply to other 
    procedures in lieu of or in addition to the process described in this 
    rule so long as the other process is ``in accordance with this part.'' 
    The commenters stated that Congress intended the assessment to function 
    as an integrated unit with each step in the process leading logically 
    to the next. The commenters also cited the Ohio decision (Ohio, et al., 
    v. U.S. Department of the Interior, 880 F.2d 432 (D.C. Cir. 1989)) as 
    specifically emphasizing that the rebuttable presumption is 
    particularly appropriate given adherence to all of the regulatory 
    procedures that, in their totality, result in a logical, disciplined, 
    efficient, and cost-effective assessment. Several commenters argued 
    that such a provision is contrary to the statutory goal of cost-
    effectiveness. Some commenters also found the language of the provision 
    both confusing and internally inconsistent because it would be 
    impossible for ``another'' process, which is a process other than one 
    included in the rule, to still be a process that is ``in accordance 
    with'' the rule.
        Response: To eliminate confusion, NOAA has deleted the section 
    referring to other procedures from the final rule. The rule provides 
    procedural and substantive standards in Sec. 990.27 that must be 
    complied with in order for an assessment to be judged ``in accordance'' 
    with this rule. Trustees must demonstrate that their assessments are in 
    accordance with this rule on an incident-by-incident basis in order to 
    obtain the rebuttable presumption.
    
    Section 990.14--Coordination
    
    Coordination Among Trustees
        Comment: Several commenters argued that the rule should require, 
    and that OPA mandates, trustee coordination during assessments to avoid 
    an adversarial and litigation-charged atmosphere among trustees and 
    prevent double recovery of damages. Another commenter suggested that 
    the rule limit the number of trustees to those who have clear 
    restoration concerns for a particular incident. Some commenters 
    suggested that the rule deny the rebuttable presumption to trustees who 
    do not coordinate, while others suggested that an affirmative proof 
    burden of certifying a lack of double recovery should be placed on non-
    coordinating trustees. Some commenters requested that model MOUs for 
    trustee coordination be included in the rule, while others who support 
    trustee coordination and incident-specific coordination agreements, 
    applauded the omission of any model agreements.
        Response: Changes to the rule state that trustees should coordinate 
    their assessments in order to ensure there is no double recovery of 
    damages. NOAA believes that any claimant that files what appears to be 
    a duplicative claim for natural resource damages against a responsible 
    party will face a substantial burden of proof to demonstrate that the 
    claim has not already been satisfied. NOAA notes, however, that it is 
    conceivable that claims for distinct natural resource injuries 
    resulting from an incident could be effectively processed independently 
    by trustees without double recovery of damages. Finally, NOAA strongly 
    supports development of agreements among trustees, but realizes from 
    experience that it is not feasible to specify a single workable model 
    for all trustees, locales, and incidents.
        Comment: Several commenters supported the designation of a Lead 
    Administrative Trustee (LAT), so long as the rule provides flexibility 
    in this designation. These commenters suggested that the rule allow for 
    co-LATs or sequential LATs, recognizing that one trustee may be the 
    lead for restoration planning while another trustee might be the lead 
    for the implementation phase. One of these commenters stated that 
    designation of an LAT should not be mandatory. Another commenter 
    suggested that, in cases where an incident affects multiple trustees, 
    the state trustee should be the LAT because of superior knowledge of 
    ``local'' natural resources. Still other commenters argued that the 
    rule should vest arbitration authority in a lead trustee, citing the 
    Ohio decision as stating that such a provision is ``entirely 
    reasonable.'' The commenters stated that arbitration authority would be 
    essential to settling disputes among trustees, which might disrupt 
    
    [[Page 461]]
    cooperative efforts among trustees and responsible parties.
        Response: It has been NOAA's experience that an LAT is essential to 
    efficiently and cost-effectively manage most assessments. Executive 
    Order 12,777, section 1 (56 FR 54757, October 22, 1991), requires 
    Federal trustees to designate one trustee to act as Lead Administrative 
    Trustee for incidents at which more than one federal trustee is 
    involved. NOAA has amended the rule to allow for co-LATs or sequential 
    LATs. NOAA does not believe it is necessary, advisable, or within legal 
    authority to mandate that state trustees always serve as LATs. Finally, 
    NOAA believes it is unnecessary to provide for arbitration or veto 
    authority in a single trustee, given the experience that demonstrates 
    trustees have been successful in a consensus decisionmaking approach to 
    assessments.
        Comment: One commenter specifically asked that the rule address the 
    issues associated with a trustee agency who might also be a responsible 
    party at an incident. The commenter suggested that the trustee/
    responsible party would want to work closely with co-trustees to 
    develop a restoration strategy, but recognizes that, in doing so, would 
    open itself up to the risk of shared information being used against it 
    as a responsible party. The commenter also asked if the co-trustees 
    could exclude the trustee/responsible party from the assessment if the 
    trustee/responsible party could not afford to fund the assessment 
    activities. Other commenters stated that the rule should specifically 
    preclude a trustee agency that is also a responsible party for a 
    particular incident from being eligible to be an LAT for that incident. 
    The commenters suggested that such a provision would avert conflicts of 
    interest, minimize problems of public perception, and help the trustee/
    responsible party fulfill its dual obligations.
        Response: NOAA notes that the rule cannot exclude participation by 
    any trustee. Where a trustee is also a responsible party, all of the 
    co-trustees may want to determine among themselves the nature and 
    extent of involvement by any given trustee. Generally, participation 
    should not be denied unless it would impede the assessment or be an 
    inherent conflict of interest.
    Coordination With Response Agencies
        Comment: One commenter suggested that the rule explicitly state 
    that restoration actions by trustees are intended to supplement the 
    initial response and cleanup activities of response agencies. Another 
    commenter suggested that the rule require that response agencies 
    coordinate with trustees.
        Response: NOAA agrees that restoration actions by trustees are 
    intended to supplement the initial response and cleanup activities of 
    response agencies. NOAA believes that response agencies and trustees 
    should coordinate during the response phase to prevent or minimize 
    residual injuries to natural resources that would require restoration. 
    However, OPA does not grant NOAA authority to place requirements on 
    response agencies.
    Coordination With Responsible Party
        Comment: Several commenters stated that early and substantial 
    involvement of the responsible party in the assessment would 
    significantly reduce the threat of litigation and facilitate cost-
    effective, feasible restoration. Some of these commenters, however, 
    stated that the rule language is somewhat ambiguous and vague as to the 
    timing and extent of that participation, as well as the extent of the 
    trustees' discretion in excluding or refusing to continue responsible 
    party participation. These commenters suggested that the rule should 
    provide for mandatory participation by the responsible party, unless 
    the trustee can demonstrate that such participation will interfere with 
    trustees' fulfilling their responsibilities under the rule and OPA. One 
    of these commenters suggested that the rule provide that the parties 
    seek mediation if reasonable disagreements develop, to prevent trustees 
    unfairly characterizing the responsible party as interfering. Another 
    commenter stated that the responsible party should be involved in the 
    entire process as soon as trustees arrive on site and that the trustees 
    should not be allowed to exclude a responsible party unless there is 
    clearly documented evidence that the responsible party is intentionally 
    undermining the process. Another commenter suggested that the rule 
    encourage the parties to enter into an agreement respecting the 
    coordination of responsible party participation, with trustees 
    prohibited from imposing conditions that are not directly related to 
    the efficient coordination of the process.
        Other commenters expressed concerns with participation by the 
    responsible party. These commenters argued that the rule should ensure 
    that trustees have the discretion as to whether, when, and how the 
    responsible parties are permitted to participate and when the trustees 
    will be able to dismiss a responsible party that is interfering with 
    the process. One commenter also suggested that the decision to exclude 
    a responsible party from the process should not be reviewable, so that 
    trustees would not have to divert time and resources in defending that 
    decision. Several commenters stated that the rule needs to be 
    consistent among sections in the provisions for responsible party 
    participation. Some commenters pointed out that the responsible party's 
    role is unique from that of the public represented by the trustees, in 
    that the responsible party has an interest in protecting the investment 
    of its owners and stock holders, and that this natural conflict of 
    interest should be acknowledged by the rule.
        Some commenters suggested additional or alternative considerations 
    for responsible party participation, including the level of cooperation 
    provided by a particular responsible party in prior incidents and the 
    willingness of the responsible party to defer to the trustees' final 
    decisions. Other commenters stated that the responsible party should be 
    subject to the same administrative record rules as the trustees and, 
    therefore, be precluded from assembling experts and data outside the 
    public process. One commenter noted that a need for funding should not 
    be a determining factor in involving the responsible party in the 
    assessment, while another commenter stated that the rule should require 
    that the responsible party fund the assessment, requiring that the 
    responsible party place the trustees' estimate of costs in escrow.
        Response: NOAA believes that open and cooperative assessments 
    performed by trustees and responsible parties can result in the most 
    expeditious and cost-effective assessments and restoration. NOAA has 
    clarified the rule to require trustees to invite identified responsible 
    parties to participate in the assessment as early as practicable, but 
    no later than issuing the Notice of Intent to Conduct Restoration 
    Planning. NOAA has also clarified the rule to indicate that it is 
    within trustees' authority to determine to what extent responsible 
    parties may participate, and that trustees can terminate or limit 
    responsible party participation if it interferes with trustees 
    fulfilling their statutory obligations. The rule specifies that the 
    minimum level of participation that will be afforded to responsible 
    parties is notification of all determinations required by trustees 
    under the rule, and notice and comment opportunity on all documents 
    that may significantly affect the direction or outcome of assessment 
    decisions. In no 
    
    [[Page 462]]
    event may trustees delegate essential statutory decisionmaking powers 
    to responsible parties. The rule also now includes guidance, such as 
    that suggested by the commenters, to determining the nature and extent 
    of responsible party participation. Responsible party funding is not a 
    pre-condition to their participation. The rule also strongly encourages 
    formal agreements between trustees and responsible parties so as to 
    ensure cooperation and cost-effectiveness. The parties are encouraged 
    to reach agreement on a list of facts, such as the natural resources 
    injured, the extent of injury, the most appropriate assessment 
    procedures to determine injury and/or restoration needs, and how the 
    results of the procedures will be interpreted.
    Public Involvement
        Comment: Several commenters noted that public involvement should be 
    clearly designed so as not to detract from the primary goal of 
    restoration in a timely manner. One commenter suggested a graded 
    approach to public involvement. Some commenters noted the potential 
    expenses of public involvement. One of these commenters stated that 
    increased costs of public outreach efforts should be explicitly 
    included in recoverable assessment costs or trustees will be unable to 
    comply with these requirements. Another commenter stated that trustees 
    should be required to give notice to the responsible party regarding 
    the stages at which opportunities for public involvement will be 
    provided. One commenter, however, stated that the rule should expand 
    the provisions for public involvement and allow such involvement in 
    several stages of the process.
        Response: Public involvement is required by OPA in development of 
    restoration plans. NOAA considers that this requirement will be 
    fulfilled by allowing, at a minimum, opportunities for public 
    involvement in development of draft and final restoration plans that 
    will form the basis of any claim for damages. However, NOAA notes that 
    it may be advantageous or necessary to seek broader public input, 
    depending on the circumstances of a particular incident, particularly 
    when that input can be obtained from members of the public that may 
    have particular expertise concerning the affected environment or 
    proposed assessment or restoration approaches. NOAA is mindful that 
    restoration decisions made by trustees are made on behalf of the 
    public, so public involvement should augment the decisionmaking 
    process. Involving the public does not need to be excessively costly if 
    it is well-planned and tailored to the incident. The costs of public 
    involvement required by OPA are recoverable assessment costs. Finally, 
    as a member of the affected public, responsible parties will be 
    notified when trustees seek public input.
    
    Section 990.15--Facilitation of Restoration
    
        Comment: Several commenters expressed strong support for pre-
    incident planning, some stating that such exercises should be required 
    by the rule. Some of these commenters pointed out that the rule should 
    encourage involvement of response agencies, natural resource managers, 
    and area industry representatives in the planning process. The 
    commenters also requested that the rule clarify how these plans might 
    be coordinated with or included in Area Contingency Plans or U.S. Fish 
    and Wildlife Service Recovery Plans and Habitat Conservation Plans. One 
    commenter specifically suggested that the rule add consideration of 
    pre-incident baseline and injury data-collection procedures and 
    protocols to the list of possible pre-incident planning activities. One 
    commenter asked for clarification as to whether pre-incident planning 
    would be subject to NEPA.
        Response: NOAA has clarified the rule to indicate that potentially 
    responsible parties, appropriate response personnel, local governmental 
    natural resource management entities, and local environmental groups or 
    representatives should be included in any pre-incident planning. NOAA 
    does not believe it has the authority to mandate pre-incident planning 
    under this rule, but does note that Area Contingency Plans or U.S. Fish 
    and Wildlife Service Recovery Plans and Habitat Conservation Plans may 
    provide an efficient focal point for structuring pre-incident damage 
    assessment planning. Finally, NOAA does not believe that pre-incident 
    planning is subject to NEPA, except where Regional Restoration Plans 
    serve as, or become part of, a programmatic Environmental Impact 
    Statement process.
        Comment: One commenter supported further development of Regional 
    Restoration Plans with extensive federal and state natural resource 
    agency coordination. The commenter noted, however, that funding for 
    such planning activities is in question and asked for any information 
    on available funding sources for such plans, other than recovered 
    damages.
        Response: NOAA believes that activities such as identifying 
    planned, proposed, or desired environmental restoration projects, 
    particularly for areas expected to be injured often or severely by 
    incidents, can provide a highly cost-effective means to identify 
    appropriate restoration alternatives for particular incidents. NOAA 
    suggests that development of these project databases can be a useful 
    addition to pre-incident planning activities. Funding for these 
    activities may come from a variety of sources such as joint funding by 
    trustees and those parties potentially liable under OPA for 
    restoration. Regional restoration planning in some areas is already 
    being performed pursuant to other authorities, such as the National 
    Estuary Program Plans.
    
    Section 990.16--Review of Rule
    
        Comment: Some commenters expressed support for NOAA's commitment to 
    review and revise this rule every five years, especially with the need 
    to keep the OPA rule consistent with the CERCLA rule, which is reviewed 
    every two years.
        Response: NOAA has determined that the specific five-year review 
    provision is unnecessary. NOAA is committed to maintaining the accuracy 
    and relevance of the assessment process described in the rule and will 
    make every effort to keep it current.
    
    Subpart B
    
    Section 990.20--Relation to CERCLA Rules
    
        Comment: Several commenters spoke of the need for consistency 
    between the OPA and CERCLA rules, with one reviewer stating that the 
    proposed OPA rule does not seem to be coordinated with the CERCLA rule. 
    Another commenter asked, given that the OPA rule is substantially 
    different from the CERCLA rule, whether DOI will incorporate OPA rule 
    changes into its regulation so that it is effective for incidents 
    inland and in the Great Lakes areas, or whether trustees and 
    responsible parties have to operate within two separate processes. 
    Another commenter suggested that the OPA rule is confusing in its 
    discussion about where the OPA rule will supersede 43 CFR part 11.
        Response: The Department of the Interior participated in the 
    interagency working group that drafted and reviewed the OPA rule. Thus, 
    NOAA and DOI took advantage of the experience gained in applying the 
    CERCLA rules. The rule was also formulated in recognition of the 
    differences between oil and hazardous substances, and the different 
    nature of 
    
    [[Page 463]]
    the incidents involving these two types of products. NOAA has referred 
    questions regarding incorporation of OPA rule provisions into the 
    CERCLA rule to DOI. However, it should be noted that the OPA rule does 
    apply to incidents in all navigable waters, which would include inland 
    incidents and incidents in the Great Lakes. NOAA has clarified the rule 
    to incorporate statutory language regarding where the OPA rule 
    supersedes 43 CFR part 11.
        Comment: One commenter questioned whether coal tar and other coal-
    derived chemicals are more appropriately classified as hazardous 
    substances, and covered by CERCLA rule, rather than the OPA rule.
        Response: NOAA notes that whether coal tar and other coal-related 
    chemicals are oils or hazardous substances is an on-going issue that is 
    being evaluated by the federal agencies implementing OPA.
    
    Section 990.22--Prohibition on Double Recovery
    
        Comment: One commenter suggested that requiring consideration of 
    independent actions of other trustees may not be possible if trustees 
    are acting separately rather than together.
        Response: Trustees must diligently avoid double recovery of 
    damages. In NOAA's experience, the identity of other trustees with 
    interests in incidents has always been ascertainable early in the 
    process, thus facilitating efforts to coordinate assessment objectives 
    and activities.
    
    Section 990.23--Compliance With NEPA and the CEQ Regulations
    
        Comment: Some commenters noted that rigid compliance with NEPA 
    notice requirements may not be desirable or necessary for incidents 
    involving non-federal trustees, and that these notice activities should 
    be optional at trustees' discretion. The commenters also suggested the 
    rule should explicitly state that the provisions of the rule fulfill 
    the public notice requirements of NEPA, even without providing the 
    Notice of Intent to Conduct Restoration Planning.
        Response: The rule has been amended to indicate that NEPA 
    compliance is solely a federal trustee requirement, and that the 
    procedures entailed in compliance will vary depending on the identity 
    of federal trustees involved and their regulations governing their own 
    NEPA conduct. The notice requirements contained in various sections of 
    the final rule are not related solely to NEPA compliance, but are 
    important elements to facilitate the open and cooperative process 
    envisioned in this rule and OPA.
    
    Section 990.25--Settlement
    
        Comment: Some commenters were concerned that the U.S. Department of 
    Justice (DOJ) will impede settlements, that state trustees can restore 
    natural resources in a more efficient manner through administrative 
    agreements, and that the rule should provide guidance for the scope and 
    timing of DOJ participation. One of these commenters suggested that DOJ 
    taking 3% of settlement sums for participation is unwarranted and, 
    perhaps, an improper use of restoration money.
        Response: Except where explicitly provided by statute, only the 
    Department of Justice has the authority to compromise claims of the 
    United States. One of these exceptions, applicable to some federal 
    trustees operating under OPA, is a provision allowing executive 
    agencies to compromise claims within their authority when such claims 
    do not exceed $100,000, or such other amounts as the Attorney General 
    may from time to time prescribe (33 U.S.C. 3711). The Department of 
    Justice plays a vital role in ensuring that the laws of the United 
    States are applied similarly by different federal agencies. The costs 
    to the Department of Justice of collecting recoveries for claims of the 
    United States in civil litigation, as authorized by H.R. 2519 (November 
    16, 1993), should be included in the estimated costs of the assessment 
    so that restoration money is not impacted.
        Comment: Several commenters disagreed with the rule's provisions 
    concerning terms of settlements. One commenter argued that the decision 
    to accept such a settlement should be within the discretion of a 
    trustee, so long as it is reasonable and justified. Some commenters 
    stated that this provision could be read as establishing substantive 
    standards to govern adequacy of a settlement, which would be 
    inappropriate and outside NOAA's authority. Several of these commenters 
    suggested that the rule simply provide that settlement sums may only be 
    expended in accordance with a restoration plan that is made available 
    for public review.
        Response: NOAA has revised the settlement provision, now 
    Sec. 900.25, to reflect the standard of review that federal courts have 
    used in reviewing natural resource damage assessment settlements under 
    other laws, and settlements by federal agencies in general. Federal 
    courts will look favorably upon the determination by an agency 
    entrusted with authority to prosecute laws that a settlement of a claim 
    is in the public interest--that it is fair, reasonable, adequate, and 
    consistent with the purposes of the governing statute. With respect to 
    OPA, NOAA expects that a court will look to see that a trustee has made 
    a determination of the adequacy of the settlement to restore, 
    rehabilitate, replace, or acquire the equivalent of the injured natural 
    resources and services. NOAA recognizes that in reviewing an agency's 
    action in accepting a settlement a court will also look to such factors 
    as litigation risk, time and expense to litigate, and advantages to 
    obtaining an immediate recovery through settlement, rather than through 
    litigation.
    
    Section 990.26--Emergency Restoration
    
        Comment: One commenter argued that the On-Scene Coordinator (OSC) 
    must authorize emergency restoration and that trustees act in a 
    consultative role during the removal phase. Another commenter suggested 
    that any emergency restoration action had to be tied into the National 
    Response System to alleviate any potential contradictory actions or 
    interference with the OSC's actions. One commenter suggested that 
    trustees do not have independent authority to act or intervene in 
    response activities during that phase. This same commenter noted, 
    however, that the requirement that responsible parties and the public 
    be notified of emergency restoration actions, with the responsible 
    parties additionally being invited to participate, will tend to foster 
    cooperation and trust. Another commenter asserted responsible parties 
    should be invited to participate at first notice of an emergency, not 
    within a ``reasonable time frame.'' Several commenters supported 
    allowing responsible parties to implement emergency restoration. 
    Another commenter suggested that notice to the public or responsible 
    parties should be discretionary due to the time-sensitive nature of 
    such actions.
        Response: NOAA fully agrees that any actions conducted during the 
    response phase should not interfere with nor be independent of the 
    OSC's activity. The rule is clear that the OSC must be notified prior 
    to implementation of emergency restoration actions by trustees, and 
    that emergency restoration may not interfere with response actions. 
    Further, the rule requires that any emergency restoration actions must 
    be coordinated through the trustee Regional Response Team (RRT) member 
    or designee, since the RRT is a part of the National Response System, 
    and that this member must work through the OSC to ensure adequate 
    coordination. In addition, the National Oil and 
    
    [[Page 464]]
    Hazardous Substances Pollution Contingency Plan (NCP), 40 CFR part 300, 
    is clear on the types of and procedures for coordination between the 
    trustees and the OSC, who retains overall responsibility for activities 
    during response. However, only trustees, not response entities, have 
    the authority to assess injuries and collect restoration costs under 
    OPA. NOAA has clarified the rule to indicate that known responsible 
    parties must be notified and invited to participate in emergency 
    restoration actions, to the extent time permits. Notice to the public 
    is provided to the public, to the extent practicable, of these planned 
    emergency restoration actions.
        Comment: Another commenter noted that the requirement that 
    emergency restoration costs should not be unreasonable appears to 
    appropriately suggest that trustees must affirmatively demonstrate the 
    reasonableness of such costs, without any entitlement to the rebuttable 
    presumption.
        Response: If trustees responsibly make a determination that 
    emergency restoration is needed to prevent or minimize natural resource 
    injury, that the action is feasible and likely to succeed, and that the 
    costs of such action are not on their face excessive compared to the 
    expected benefits in limiting injury, then emergency restoration 
    actions and costs are reasonable, and entitled to a rebuttable 
    presumption.
        Comment: Another commenter questioned whether there are any 
    exclusions for liability for damages resulting from any additional 
    injuries caused by the emergency restoration or response actions.
        Response: Liability for natural resource damages extends to 
    injuries that result from reasonable and necessary response and 
    emergency restoration actions taken in response to an actual or 
    threatened discharge of oil.
    
    Section 990.27--Use of Assessment Procedures
    
    Criteria for Selecting Assessment Procedures--General
        Comment: One commenter noted that the greater flexibility in 
    assessment procedures provided by the proposed rule is likely to result 
    in greater likelihood of litigation. Another commenter suggested that 
    such flexibility may result in trustees applying numerous procedures, 
    charging the responsible party with these costs, then basing their 
    claim on the procedures that yield the highest damage figure. Another 
    commenter stated that the trustees should be required to document the 
    decision as to why a particular assessment procedure was chosen.
        Other commenters, however, agreed with the rule listing criteria 
    that assessment procedures should meet, rather than specifying 
    acceptable procedures themselves. Some commenters suggested that 
    trustees must be provided flexibility to select the most efficient 
    procedure to assess injuries, based upon factors such as reasonable 
    cost, validity, reliability, and incident-specific considerations, 
    however, one of these commenters suggested that the rule should simply 
    require that procedures be reliable, valid, and cost-effective as 
    minimum criteria and that other incident-specific factors should be 
    considered in selection of procedures.
        Response: In eliminating categories of assessment procedures, and 
    providing instead a list of standards to guide selection of the most 
    appropriate assessment procedure for the injury and incident at hand, 
    the rule will make assessments less rigid and more cost-effective, and 
    NOAA expects this will reduce litigation by fostering cooperative 
    settlements. The rule expressly prohibits the approach suggested by the 
    commenter in which trustees may apply a suite of procedures to produce 
    the highest damages estimate, and charge for all of the procedures 
    used. This approach would clearly violate provisions of Sec. 990.27 and 
    the definition of reasonable assessment costs. Finally, standards for 
    selecting assessment procedures, and the types of assessment procedures 
    available, are now included in Sec. 990.27.
        Comment: Most commenters applauded the approach taken in subpart E 
    of the proposed rule to provide generic standards for possible 
    assessment procedures, given the universe of procedures available and 
    possible injuries likely to result from incidents. However, several 
    commenters were concerned that some of the proposed criteria might be 
    mutually exclusive and difficult to meet for all incidents. For 
    instance, one commenter noted that procedures that meet the criterion 
    that procedures must provide information useful in determining and 
    quantifying restoration needs, might not be the most cost-effective 
    procedures. The commenter also noted that procedures that provide 
    information required for restoration determinations may entail 
    additional costs with no assessment benefit, violating the requirement 
    for consideration of cost. Some commenters suggested that none of these 
    criteria be mandatory, or that only the ``cost-effectiveness'' and 
    ``valid and reliable'' criteria might be appropriately mandatory.
        Response: The standards for acceptable procedures were moved from 
    subpart E of the proposed rule into a new section, Sec. 990.27, to 
    emphasize that these standards apply to any and all procedures used in 
    performing assessments under this rule. Procedures must meet the 
    standards in order to be deemed part of an assessment in accordance 
    with this rule. The concerns that one standard may be contrary to 
    another have been resolved. The standards now provided in Sec. 990.27 
    must all be met, but the criterion concerning restoration information 
    has been changed to a recommendation, rather than a requirement, in 
    recognition that procedures that provide information useful in 
    restoration scaling are not always available, nor are they always cost-
    effective.
        Comment: Some commenters were concerned that the criteria requiring 
    cost-effectiveness and weighing benefits of a procedure against its 
    costs might be interpreted to require strict cost-benefit analyses of 
    all possible procedures, inappropriately diverting trustee efforts from 
    assessment work, and needlessly driving up costs. A few other 
    commenters suggested that strict cost-benefit analyses should be 
    required. One commenter suggested that the balance should more 
    appropriately weigh expected assessment costs against overall expected 
    damages, because assessment costs cannot be meaningfully scrutinized 
    relative to expected informational benefits from an assessment 
    procedure.
        Response: The various standards for procedures were never intended 
    to require a strict cost-benefit analysis. The rule language has been 
    revised to indicate that additional costs of more complex procedures 
    must be reasonably related to the expected increase in information 
    provided by those procedures. The standards are intended to guide 
    trustees in selecting individual assessment procedures and discourage 
    trustees from using procedures that do not provide information 
    beneficial for restoration planning purposes.
        Comment: Some commenters suggested that the terms ``reliable'' and 
    ``valid'' should be expressly defined. Various definitions were offered 
    by the commenters.
        Response: The technical definitions of the terms ``reliable'' and 
    ``valid'' vary in usages of the terms across various disciplines. In 
    general, under this rule, these terms refer to technical judgments by 
    experts in a particular field that a procedure is consistent with best 
    technical practices for the measure 
    
    [[Page 465]]
    being investigated under the circumstances.
    Specific Procedures
        Comment: Many of the commenters' discussion on assessment 
    procedures focused on how specific procedures might relate to the 
    standards provided in the rule. Some commenters were concerned that the 
    listing of procedures in the appendix to the preamble might be 
    interpreted as an endorsement of those procedures. The commenters 
    requested that the rule state that procedures that do not meet the 
    criteria are not entitled to the rebuttable presumption. The commenters 
    noted that, if specific procedures are listed in the preamble, NOAA has 
    a duty to provide additional standards relating to the use of such 
    procedures, either in the rule or in guidance documents. Other 
    commenters stated that the rule should clarify that reliable and valid 
    procedures are not limited to those specifically listed in the preamble 
    and should not necessarily be excluded from use under the rule.
        Response: Assessment procedures must meet the standards in the rule 
    in order to be deemed part of an assessment conducted in accordance 
    with this rule. No explicit or implicit endorsement, nor lack of 
    endorsement, is intended to be given to the specific identification or 
    omission of any particular procedure in either the preamble or rule. It 
    is not feasible for the rule to identify all acceptable procedures, nor 
    the acceptable applications of those procedures, for all possible 
    circumstances of all incidents. Procedures and their applications must 
    be evaluated on a case-by-case basis.
        Comment: A number of commenters stated that NOAA should not 
    establish requirements for use of procedures and strongly supported 
    NOAA's decision to remove specific guidance on the application of 
    certain procedures (e.g., contingent valuation, benefits transfer). The 
    commenters suggested that discussion on how to apply specific 
    procedures should be placed in guidance documents. One commenter 
    suggested that the rule should allow trustees to use any criteria that 
    are generally accepted by the scientific community. One commenter 
    stated that the four criteria listed in the rule are still 
    insufficient, and could be strengthened by distilling the most 
    important guidelines in the guidance documents into rule language so 
    that they will be binding upon trustees.
        Response: NOAA believes that discussion on the appropriateness and 
    use of specific assessment procedures is more suited to guidance 
    documents. The commenters should refer to these guidance documents as 
    well as the literature for support along this line.
        Comment: Another commenter asked that the rule clarify that 
    trustees may use models or extrapolate from literature when it is more 
    appropriate and cost-effective than gathering site-specific data.
        Response:  The rule, in Sec. 990.27, provides that such procedures 
    as models or literature extrapolation that meet the standards for 
    acceptable procedures are available for use in accordance with the 
    rule.
    Option of Responsible Party to Request Alternative Procedures
        Comment: Some commenters argued that trustees should be required to 
    use an incident-specific procedure when the conditions in the rule are 
    met. However, the commenters stated that the conditions currently in 
    the rule are contrary to OPA because they force the responsible party 
    to waive the right to challenge the reasonableness of the assessment 
    costs. The commenters argued that this would force responsible parties 
    to choose between using a procedure that may assess non-existent 
    damages and waiving their statutory right to expect reasonable 
    assessment costs. Another commenter noted that the responsible party 
    should not have to advance the assessment costs if the responsible 
    party can demonstrate that an incident-specific assessment is really 
    appropriate and warranted. Some commenters also suggested that the rule 
    specify a time frame for the responsible party request, such as 21 days 
    from the time of the incident, rather than the ambiguous ``acceptable 
    time frame'' currently in the rule.
        One commenter pointed out that responsible parties would want to do 
    expanded assessments in any case in order to assist in the defense of 
    third party claims.
        Some commenters noted that detailed field studies may be expensive 
    and in those instances where the likelihood of injury is so high as to 
    not require extensive study, trustees and responsible parties may agree 
    that non-field-based procedures may be used.
        Other commenters argued that the ultimate decision on assessment 
    procedures should always be left to the trustees. The commenters 
    suggested that, if trustees determine that procedures selected by a 
    responsible party are technically unsound or would inadequately address 
    natural resource injuries, then the trustees should have the ability to 
    modify or reject the request. Some commenters also noted that the rule 
    should be clarified to state that the responsible party must advance 
    the trustee's estimate of the costs of conducting the incident-specific 
    assessment.
        Response: The final rule has clarified, in Sec. 990.14(c), the 
    conditions for the responsible party option to request a different 
    procedure than that selected by the trustees. The option will be 
    provided to responsible parties who have accepted the trustees' 
    invitation to participate in an assessment, and who are doing so 
    cooperatively. Alternative procedures proposed by the responsible party 
    must meet the standards for acceptable procedures provided in 
    Sec. 990.27. The rule allows trustees to reject the responsible party's 
    request if the alternate procedure, in the judgment of trustees, is not 
    technically feasible, not technically or scientifically sound, and 
    could not be completed within a reasonable time frame. Because 
    participating responsible parties will have already been afforded 
    opportunity to review and comment on proposed procedures that trustees 
    have selected in accordance with Sec. 990.27, the responsible party 
    option is really a mechanism to resolve disputes between trustees and 
    responsible parties as to the most appropriate procedure for the injury 
    and incident at hand. Responsible parties should be willing to fund 
    alternative procedures they feel strongly about, given that trustees 
    will have already made a determination that other procedures are 
    appropriate, and they should agree not to challenge the results of 
    procedures that they request be used. The rule has removed the 
    requirement that responsible parties agree not to challenge the costs 
    of those requested procedures.
    Simplified Procedures--General
        Comment: Several commenters raised objections to the use of 
    simplified assessment procedures. Several commenters argued that all 
    existing simplified procedures, federal and state, are flawed and 
    unreliable. The commenters argued that these procedures should not be 
    used without any field verification. Several of these commenters stated 
    that any procedure that generates average values is by definition not 
    incident-specific as required by OPA, basic requirements for proof of 
    injury and causation in tort, and recent case law on causation 
    requirements.
        Several commenters argued that there are strong statutory arguments 
    against simplified procedures under OPA. Some of these commenters 
    stated that the wording of the various sections of OPA that set forth 
    the natural resource damage provisions and describe liability 
    
    [[Page 466]]
    under OPA all explicitly speak to direct impacts ``resulting from'' a 
    particular incident, not some speculative concept of what might have 
    resulted from the incident. The commenters cite section 1002(b)(2)(A) 
    of OPA (33 U.S.C. 2706(b)(2)(A)), ``damages . . . that result from such 
    incident,'' and section 1006(e)(1) of OPA (33 U.S.C. 2706(e)(1)) 
    calling for rules to assess damages ``resulting from the discharge of 
    oil.'' These commenters also noted legislative history associated with 
    these provisions in OPA. A House Committee Report (H. Rep. No. 241, 
    Part 1, 101st Cong., 1st Sess. at 34(Sept. 13, 1989)) is quoted 
    supporting recovery for ``the natural resources that were injured.'' 
    Also quoted was the Committee of Conference Report (H.R. (Conf.) Rep. 
    No. 101-653, 101st Cong., 2d Sess. (1990) at 103) which refers to 
    damages ``resulting from an incident.'' These commenters also argued 
    that Congress rejected simplified procedures under OPA because an early 
    draft of a Senate bill (S. 686, 101st Cong., 1st Sess., 
    Sec. 102(d)(3)(A)(1989)) calling for simplified assessments was not 
    incorporated into the final bill. The commenters stated that Congress 
    could have adopted the type A model, which was in existence during the 
    development of OPA, but didn't. In fact, the commenters noted that the 
    Conference Report (at 109) explicitly states that the OPA rule, not the 
    CERCLA rule, which contains the type A model, would apply to 
    assessments under OPA.
        Some commenters referred to the procedures and requirements 
    promulgated by the U.S. Department of Transportation concerning claims 
    against the Oil Spill Liability Trust Fund (57 FR 36314 (Aug. 12, 
    1992)) and suggested that such a claim would be rejected if based upon 
    simplified procedures because such claims would not be based upon 
    evidence of damages. These commenters argued that trustees must show 
    evidence of actual exposure and actual injury at all levels of 
    biological organization, not use models or literature to extrapolate 
    upon evidence of exposure of some natural resources or lower-level 
    biota to predict indirect exposure and a pathway to other, higher-
    level, biota. The commenters argued that models and literature-based 
    procedures are unreliable and tend to overstate injury and cannot take 
    into account the various incident-specific factors that affect the 
    outcome of incidents.
        Several commenters argued that these procedures may result in 
    double recoveries for the same natural resources when one or more 
    trustees and private claimants make claims based on the same natural 
    resources, with a few commenters suggesting that these procedures 
    promote uncoordinated actions by trustees.
        Some commenters stated that simplified assessment procedures, 
    including models, need to incorporate uncertainty by, perhaps, giving a 
    range of possible results rather than one definitive answer. Other 
    commenters requested that any and all simplified procedures that might 
    be included in the rule should be final procedures, submitted for 
    public and industry review. Some commenters requested that the rule 
    should provide sufficient standards and guidelines for the use of 
    simplified procedures, including threshold levels for the use of those 
    approaches.
        One commenter suggested an alternative to the simplified procedures 
    listed in the rule. The commenter suggested that NOAA should develop a 
    decision tree-based simplified procedure that would enable trustees to 
    collect limited field samples and/or make minimal field observations 
    and then, based on a process outlined in the rule, make a determination 
    in cooperation with the responsible party of what, if any, restoration 
    alternatives should be pursued.
        Other commenters stated that NOAA has unquestionable statutory 
    authority to promulgate rules that include models and formulas. The 
    commenters argued that the legislative history of OPA demonstrates 
    Congress's desire to simplify assessment procedures and, therefore, it 
    is NOAA's responsibility to accurately and cost-effectively promulgate 
    the necessary procedures to make the public whole for injuries it has 
    sustained. These commenters argued that it would be a waste of public 
    and private resources to require trustees to conduct incident-specific 
    assessments of injury when experience, models, and the literature are 
    adequate to predict injury. The commenters pointed out that an 
    assessment that incorporates the extensive preexisting body of 
    knowledge is reliable, valid and on solid scientific standing.
        Some commenters expressed surprise over the depth of concern 
    regarding the use of the simplified assessments, since they should 
    reduce the costs of determining restoration alternatives and provide 
    consistency to the process. These commenters indicated that the data 
    and the ``bugs'' in the simplified procedures should be the concern, 
    rather than the use of the procedures per se.
        The commenters stated that the argument that computer models fail 
    to provide an incident-specific damage assessment is without merit. The 
    commenters pointed out that model-based assessments may not be exact, 
    but the same can be said for physical sampling or any scientific 
    process in which averages are employed to approximate the true 
    conditions. The commenters noted that computer analysis is simply 
    another tool to be used in damage assessment and that, if responsible 
    parties are concerned that liability for damages will be inaccurately 
    determined using models or compensation formulas, they can simply opt 
    to have a full-scale field research operation.
        Other commenters pointed out that the proposed rule listed only two 
    types of simplified procedures, which could easily be misinterpreted to 
    mean that these are the only two simplified assessment procedures 
    usable under this section. To correct this problem, the commenters 
    suggested that additional language is needed in the rule to provide 
    flexibility and efficiency in the use of simplified procedures. The 
    commenters requested that NOAA expand the description of ``simplified 
    procedures'' by specifically referencing other procedures such as state 
    formulas, or procedures such as habitat equivalency analysis. These 
    commenters stated that the use of simplified procedures is the only way 
    to determine restoration costs for the thousands of small incidents 
    that occur annually, since trustees lack the personnel, time and 
    financial resources to conduct in-depth, incident-specific assessments 
    for each and every incident. Some commenters argued that, without 
    procedures to address the vast majority of incidents, NOAA is failing 
    to implement the intent of Congress to provide regulations that allow 
    trustees to efficiently, reliably, and cost-effectively address the 
    injuries to public natural resources from incidents.
        Other commenters argued that, since most incidents are less than 
    1000 gallons, NOAA should make it a priority to include in the rule a 
    credible simplified tool. The commenters suggested that the lack of 
    such a procedure will result in a rule that does not fully meet the 
    intent of OPA, since, at this time, the options listed in the rule are 
    not available to trustees, nor is there any guarantee that they will 
    ever become available. The commenters stated that provisions should be 
    included in the rule that would allow for the development and use of 
    other simplified procedures. Other commenters specifically suggested 
    that passive values should be incorporated into these simplified 
    procedures. 
    
    [[Page 467]]
    
        Response: NOAA agrees that OPA intends that responsible parties be 
    held liable only for restoration needed to redress the injuries caused 
    by specific incidents. NOAA does not believe that simplified 
    procedures, such the type A model per se, contravene the OPA liability 
    limitations to actual injuries caused by specific incidents. However, 
    the rule does not suggest, state, or imply that these procedures are 
    acceptable procedures in all instances. Like any assessment procedure 
    proposed for use under the rule, simplified procedures must meet the 
    criteria for acceptable procedures listed in new Sec. 990.27. If a tool 
    is not appropriate for the circumstances of an incident, it cannot be 
    used and still receive a rebuttable presumption for assessments 
    performed in accordance with this rule. The final rule, however, does 
    not explicitly reference ``simplified'' procedures as a distinct 
    category of assessment procedures, and does not identify any particular 
    procedure(s) as appropriate for particular circumstances. This 
    determination must be made by trustees on an incident-by-incident 
    basis.
        NOAA places no significance on the omission of reference to 
    simplified procedures in the final language of OPA. Congress merely 
    chose not to tie NOAA's hands in promulgating these rules. The same 
    conference committee report relied upon by many commenters to disavow 
    simplified procedures states that these regulations should be designed 
    to simplify the trustees' task of assessing and recovering the full 
    measure of damages resulting from an incident. NOAA believes that 
    Congress clearly intended that the rule should facilitate prompt, cost-
    effective restoration, by providing a technical framework focused on 
    restoration, not on needless scientific experimentation.
        While simplified procedures may be used as a stand-alone assessment 
    procedure for small incidents, these procedures are rarely, if ever, 
    used for larger incidents without some level of field assessment. In 
    these instances, simplified procedures are used to quantify the extent 
    of injury and scale restoration actions only after field investigations 
    have determined that natural resources have been exposed, injuries have 
    been demonstrated, or lost use has occurred.
    Type A Model
        Comment: Several commenters argued that there are serious 
    shortcomings in DOI's proposed type A models, and that NOAA should not 
    allow use of these models in their current form under any conditions. 
    Some of these commenters argued that NOAA should reserve this section 
    until the models are made reliable. The commenters raised specific 
    objections to certain provisions of the proposed type A models (e.g., 
    cleanup and containment of oil, use of dispersants, bird oiling 
    probabilities, boating and fishing closures, potentially grossly 
    disproportionate restoration costs, possibly arbitrary and speculative 
    mitigation costs). Many of these commenters argued that these 
    unexplained problems make the proposed models unusable. Other 
    commenters suggested that NOAA should continue to review and revise the 
    models and subject them to further public comment.
        Some of these commenters stated that NOAA has not undertaken any 
    review of the type A models that could constitute an independent 
    finding of reliability. One of these commenters raised several 
    procedural arguments regarding the rule's adoption of the type A 
    models, particularly that adopting the proposed type A models would 
    violate the Administrative Procedure Act principles of notice and 
    opportunity for comment because the public cannot, at present, know 
    what the final type A rule would be in the future. The commenter argued 
    that, if NOAA wishes to use type A procedures, it must develop and 
    propose its own version and subject it to public comment. Other 
    commenters stated that the rule's criteria for the use of the type A 
    model are too vague in simply requiring conditions ``sufficiently 
    similar'' to those required under the CERCLA rule. Another commenter 
    requested that NOAA revise the rule to specify that the type A models 
    should not be used when the services provided in an area differ from 
    those contained in the models, or when field observations clearly 
    contradict model results.
        Some commenters disagreed with the use of models to assess injury 
    because of the potential for determining damages where no injury 
    exists. The commenters also argued that the lack of actual data in 
    these procedures makes it impossible for trustees to evaluate 
    restoration alternatives in the manner required by the rule. One 
    commenter, although supporting the concept of a simplified procedure, 
    urged NOAA not to adopt the type A models until they can be corrected 
    to prevent occasionally arbitrary and unreasonable results and to focus 
    on restoration, consistent with OPA. One commenter noted that 
    predictions made through the use of models should not be allowed since 
    these assume that an adverse change will always occur, whereas the 
    evidence of past incidents shows that injury is not inevitable.
        One commenter noted that, if NOAA incorporates simplified 
    procedures developed by DOI, NOAA would be engaged in a redelegation of 
    its statutory authority under OPA.
        Response: First, NOAA was not tasked with promulgating any specific 
    type of assessment procedure, thus there was no such duty that was 
    inappropriately re-delegated to DOI. Further, as discussed above, DOI's 
    type A models are not incorporated per se into the rule. Trustees 
    desiring to use the models must evaluate whether these tools meet the 
    acceptable procedures standards listed in Sec. 990.27, and if they are 
    not met, trustees must determine whether use of the tools outweighs the 
    loss of the rebuttable presumption, or whether another procedure exists 
    that does meet the acceptable procedures standards. In addition, even 
    if trustees have selected a procedure in accordance with the standards 
    in Sec. 990.27, such as the type A model, participating parties who 
    disagree with this decision can identify valid and reliable alternate 
    procedures and request that trustees implement the alternate procedure, 
    as provided in Sec. 990.14(c)(6) of the rule. Trustees must consider 
    this request and determine whether to accept or reject the request 
    based upon such factors as feasibility, validity, relevance, and 
    timeliness of the suggested procedure. The various technical concerns 
    raised by commenters may only be valid if a model is applied in certain 
    circumstances, thus it would be inappropriate to bar use of the models 
    completely under this rule.
    Compensation Formulas
        Comment: Many comments received on the compensation formula 
    proposed in 1994 deal with such issues as: utility for small incidents; 
    understating or overstating damages; questions regarding factual 
    underpinnings of the formulas; assumptions of injury built into the 
    formulas; lack of authority to promulgate non-site-specific assessment 
    procedures; predicted detrimental impacts on the oil industry; 
    conclusive nature of formulas; size of incidents appropriate for 
    application of formulas; relationship to state formulas; generation of 
    formulas from the type A models; as well as several comments about 
    specific technical or factual aspects. Several commenters on the 1995 
    proposed rule supported NOAA's decision to reserve the compensation 
    formulas and strongly urged NOAA to withdraw the formulas from the 
    final rule. Some commenters noted that the formulas were based on the 
    earlier versions of the proposed type A models and, therefore, did not 
    benefit from later 
    
    [[Page 468]]
    improvements and corrections made to those models. The commenters, 
    however, suggested that the development of the compensation formula 
    guidance document seems to confer a regulatory or legal status to a 
    tool that should be limited to an informal aid to settlement 
    discussions.
        Many commenters were concerned about the withdrawal or reservation 
    of the compensation formulas. The commenters argued that, without these 
    tools, trustees are unlikely to be able to fulfill their responsibility 
    to make the environment and public whole. The commenters noted that the 
    procedures for incident-specific assessments are too rigorous and 
    costly for most small incidents so that these small incidents will not 
    be adequately addressed, with the losses being absorbed by the public 
    in the form of lost natural resources and services.
        Several commenters pointed out that, by promulgating a compensation 
    formula, NOAA has the opportunity to provide an alternative to 
    individual state models and promote some consistency in the assessment 
    of damages resulting from smaller incidents. These commenters suggested 
    that NOAA should either recalculate the compensation formulas with the 
    most current version of the type A models and publish the formulas in 
    an interim final rule, or include the original formulas, which could 
    then be withdrawn when new formulas are published using the final type 
    A models.
        On the issue of the use of the formulas in an actual assessment, 
    some commenters specifically requested that NOAA establish that only 
    the data inputs into the formulas are contestable, but that the 
    algorithms of the formulas are not, similar to the standard for the 
    Social Security disability regulations and Medicare regulations, where 
    the diagnosis of a malady is contestable but the costs of treating the 
    malady are not.
        Response: The proposed rule of 1995 reserved the compensation 
    formula primarily due to revisions being made in the type A models on 
    which the formulas were based. The final rule, however, does not 
    incorporate compensation formulas as acceptable procedures per se; like 
    any other proposed assessment procedures, compensation formulas must 
    meet the criteria for acceptable procedures in Sec. 990.27 of the rule 
    in order to be in accordance with the rule. NOAA still supports the 
    concept of such simplified procedures as compensation formulas. NOAA 
    developed a guidance document in 1995 on how one might recreate 
    scenarios contained in the 1994 compensation formulas using the revised 
    type A models. This guidance document is still available for use. When 
    the type A models under development are promulgated by DOI as final 
    rules, NOAA intends to generate the compensation formulas again.
    Types of Assessment Procedures Available
        Comment: Several commenters argued that, because trustees would be 
    allowed to use the four listed procedures alone or in any combination, 
    trustees could recover damages that are not based on proof that the 
    incident actually and proximately caused an actual natural resource 
    injury, in conflict with OPA. Some commenters requested that the rule 
    require that the procedures be appropriate for the types of incidents 
    to which they will be applied. These commenters argued that the 
    proposed procedures lack adequate rigor and that some of the procedures 
    result in far more persuasive scientific evidence than other, abstract 
    procedures.
        Several of these commenters argued that literature-based procedures 
    are not defined and are not allowed under the CERCLA rule. The 
    commenter stated that this procedure will allow an injury determination 
    based solely on the reporting of an injury in the literature, without 
    considering the conditions existing at the incident of concern, which 
    are determinative of the effects. Other commenters argued that even 
    laboratory studies alone are insufficient to demonstrate injury in the 
    field and cannot take account of incident-specific compensatory 
    mechanisms that may be at work in an actual population of biota. The 
    commenters stated, therefore, that laboratory evidence must be combined 
    with field verification that an injury has actually occurred.
        One commenter argued that the guidance provided in the rule on 
    incident-specific procedures fails to meet basic requirements for proof 
    of injury and causation. The commenter stated that the listed 
    procedures can only, at best, suggest that injury may have occurred 
    and, therefore, should not be allowed without field verification. Some 
    commenters stated that the rule should provide explicit acceptance 
    criteria for the use of procedures to ensure that actual injury and 
    causation are established, based on scientifically valid and reliable 
    evidence that the natural resource was in fact exposed, directly or 
    indirectly, to the discharged oil (with an exception for substantial 
    threat), that the natural resource has in fact experienced injury, and 
    that exposure to oil is known to cause such injury in the field. These 
    commenters note that the rule should provide that these criteria may be 
    waived, in whole or in part, only with the concurrence of the 
    responsible party.
        Another commenter noted that trustees have broad discretion under 
    the rule to decline to use the DOI type A models, and thereby employ 
    costly incident-specific studies and analyses whose costs could equal 
    or exceed damages. The commenter recommended that the rule should 
    require trustees to use the DOI type A models whenever the criteria for 
    applying such procedures listed at 43 CFR 11.33 may be satisfied.
        Response: The rule adopts a general approach, that a range of 
    assessment procedures, from simplified to more detailed, should be 
    available to the trustees so that assessments can be appropriately 
    tailored to incidents. Procedures for documenting and quantifying any 
    particular injury must be selected by considering a variety of factors, 
    all focused on making the determination of necessary restoration 
    actions, while ensuring that assessments are technically valid and 
    cost-effective. Procedures selected must be capable of determining 
    injury pursuant to subpart E of the rule.
    Scaling Procedures Listed in Appendix B of the Preamble
    Habitat Equivalency Analysis
        Comment: Several commenters stated that HEA is a new and unproven 
    procedure and has limited application for assessments. Some commenters 
    argued that the procedure is inconsistent with economic theory since 
    there is no direct relationship between the cost of replacement and the 
    value of the natural resource. Commenters noted that HEA is based on 
    many assumptions, such as: strict proportionality between unit of 
    measure and value; substituting cost for value yields social gain; 
    marginal natural resource values assumed constant over time; and 
    service flows assumed constant and additive across time. The commenters 
    noted that fulfilling the assumption of equal unit value is difficult 
    and that the chosen metric may not reflect the unique characteristics 
    that define the flow of services from the habitat. Commenters suggested 
    that: HEA does not address fundamental assessment issues, such as: the 
    concept of baseline, making it difficult to estimate percent of 
    baseline services lost; in a complex release in which different natural 
    resource services are injured to different extents, there is no obvious 
    way short of economic valuation of the services to combine the 
    
    [[Page 469]]
    different levels of impairment into a single index which would allow 
    all the impaired natural resources to be expressed in terms of a single 
    unit; HEA is not useful for habitats that are not replaceable or 
    reproducible; and that problems occur in incorporating unit values of 
    indigenous habitat when restoration converts one habitat type to 
    another. The commenters noted that it is problematic to use HEA to 
    address lost use services, because changes that may occur in the unit 
    value of currently offered services at the improved site need to be 
    considered (e.g. effects of congestion). Also, the commenters noted 
    that physical natural resource measures do not reflect quality, and 
    thus do not reflect appropriate consumer surplus values. The commenters 
    suggested that HEA does not measure benefits of compensatory 
    replacement, increasing the chances of selecting restoration actions 
    for which the costs are disproportionate to the value of the lost 
    services. Also, other commenters noted that substitutes must be taken 
    into account when measuring service reductions.
        Other commenters, however, supported the use of HEA, stating that 
    the procedure is appropriate, cost-efficient, and effective. One 
    commenter suggested that HEA not be limited in use to ecological 
    services. The commenter stated that the description of the procedure 
    should clarify that the metrics used are simply indicators of overall 
    environmental quality, not complete measures of damages.
        Commenters suggested that, when using HEA, trustees should provide 
    evidence that the unit values of the lost and replacement services are 
    likely to be equivalent. The commenters stated that HEA should 
    explicitly account for baseline service quantification issues. The 
    commenters also argued that, because the components of HEA embody 
    substantial uncertainty, the trustees should undertake explicit 
    sensitivity analysis as part of HEA. The commenters suggested that HEA 
    should focus on overall habitat or ecosystem services and not on 
    individual organisms or specific ecosystem components not of 
    significance to overall functioning of a system. Some commenters stated 
    that HEA models should be used for biological/ecological services, not 
    human use services. The commenters also argued that the habitat or 
    species replacement cost procedure should be specifically excluded by 
    the rule, except where natural resources and/or services are actually 
    restored.
    Travel Cost Method
        Comment: Some commenters suggested that trustees should use multi-
    site random utility models instead of single-site analyses in 
    conducting travel cost studies. The commenters noted that the travel 
    cost studies should clearly show the linkage between the injuries and a 
    reduction in services, as well as allowing for unrestricted 
    substitution between recreation opportunities. Finally, the commenters 
    suggested that the sample of users should be representative of the 
    population being studied and the travel costs should be measured 
    accurately to reflect the true costs to the recreators.
    Factor Income Method
        Comment: Some commenters noted that the factor income method is an 
    unreliable procedure for calculating values when natural resources vary 
    in abundance over time. Other commenters stated that the factor income 
    approach measures private economic losses, not losses to the public, 
    and is inappropriate for use in assessments under OPA.
    Hedonic Price Model
        Comment: Commenters suggested that the hedonic price model is 
    generally inappropriate for assessments, due to major difficulties with 
    potential double recovery for public and private losses. Other 
    commenters suggested that the hedonic pricing method should not be used 
    for incidents because of the brief and temporary nature of incidents 
    and their impacts.
    Market Models of Demand and Supply
        Comment: Several commenters stated that the market models of demand 
    and supply are poorly specified in the rule, and that the rule should 
    specify their use and some standards for that use.
    Contingent Valuation
        Comment: Many of the commenters argued that CV should not be used 
    in scaling. The commenters argued that CV has not been proven reliable, 
    that it should not be used for transitory effects, and would generate 
    overstated damage claims. Some of these commenters noted that CV is a 
    highly controversial procedure, and has not survived rigorous peer 
    review within an atmosphere of impartial scientific research.
        Some commenters argued that the inherent upward bias in CV would 
    drive up the cost of restoration. However, other commenters noted that 
    concerns about CV may be satisfied if it were used in ``both sides'' of 
    the scaling calculation (i.e., to calculate both the losses from the 
    injury and the gains from the replacement action). This way, the 
    overall scale of the selected restoration alternative would likely not 
    be affected.
        Many commenters stated that the rule should allow for the use of 
    CV. Some commenters noted that CV is reliable if performed properly. 
    These commenters noted that CV has already been endorsed by the Ohio 
    court. Other commenters stated that test-retest CV experiments show 
    that CV can be reliable. Several commenters pointed out that CV is 
    essential for obtaining damages for lost passive values. Commenters 
    also argued that CV should be used in scaling. The commenters argued 
    that trustees should retain as broad a spectrum of valuation procedures 
    as possible.
        One commenter indicated that survey procedures can elicit what the 
    public needs for compensation by presenting different restoration 
    choices and, therefore, gaining information on the scale of restoration 
    actions needed. Another commenter suggested that mail-out surveys could 
    be used to assess relative values, even though the Blue Ribbon Panel 
    recommended in-person surveys for dollar determinations. Other 
    commenters noted the particular utility of parts of CV, such as focus 
    groups and survey procedures, in planning restoration.
        Many commenters argued that CV should not be included in the final 
    rule; however, that if it is included, the rule should contain specific 
    standards for its use, and it should not be accorded the rebuttable 
    presumption. Several of the commenters stated that the rule should 
    include the Blue Ribbon Panel's recommendations on study design, 
    implementation and verification. Other commenters argued that damages 
    considered by respondents in CV surveys should reflect only injuries 
    that have been established in injury determination and quantification. 
    These commenters also stated that CV scenarios should not be based on 
    willingness to pay to prevent incidents. The commenters stated that the 
    rule should provide for scope tests that: show substantial variation 
    with the size of the commodity; focus only on natural resource damages; 
    and exclude no respondents when carried out. The commenters also 
    recommended that, for response rates: standards must be developed for 
    calculating response rates and zero value should be attributed to 
    survey nonrespondents as a conservative approach to handling 
    nonresponse bias. The commenters suggested that CV should not be 
    employed in cases where nonuse values 
    
    [[Page 470]]
    are expected to be small and that additivity tests should be required. 
    The commenter also stated that a zero value should be attributed to 
    individuals unaware of the injury before the survey was administered.
    Conjoint Analysis
        Comment: Several commenters stated that conjoint analysis is an 
    unproven procedure for natural resource applications, and is not 
    reliable. Some of the commenters noted that conjoint analysis may be 
    better than CV, but it raises similar difficulties. Some commenters 
    noted the importance of realistic descriptions. The commenters also 
    suggested the procedure is subject to the potential for protest 
    valuation. The commenters suggested that, when using the procedure, 
    trustees need to define a relevant population for sampling and for use 
    in the scaling calculations. The commenters suggested that the results 
    of the analysis can be very sensitive to design decisions, 
    implementation, and interpretation decisions. The commenters pointed 
    out that preferences are still expressed under hypothetical conditions. 
    The commenters also suggested that respondents are unlikely to be 
    familiar with the different attributes and levels of habitat services 
    and are inexperienced in evaluating their relative merits, that some 
    respondents may feel the answers are the purview of scientific experts 
    rather than the general public, and that answers to early questions may 
    be of lower quality due to learning effects during course of survey. 
    The commenters stated that respondents may experience fatigue in 
    evaluating numerous options. The commenters also stated that the 
    experimental design can easily become burdensome. The commenters noted 
    the problem of environmentally correlated attributes when using the 
    procedure. The commenter noted that a component-wise valuation would be 
    useful in calculating compensatory damages for partially injured 
    natural resources. The commenters argued that, because of a close 
    relationship between conjoint analysis and CV, all the issues raised by 
    the NOAA Blue Ribbon Panel may need to be considered.
        However, some of these commenters noted that the procedure need not 
    be limited to evaluating restoration alternatives that provide services 
    of the same type and quality and subject to comparable scarcity and 
    demand conditions as interim lost services. The commenters suggested 
    that the procedure could reduce assessment costs, since a single 
    conjoint questionnaire could evaluate the lost interim services, as 
    well as the services from several different restoration alternatives.
        The commenters argued that conjoint analysis should not be used to 
    estimate passive use values. The commenters also suggested that the 
    population of survey respondents should be familiar with the goods 
    involved, the survey should present the choices in terms that are 
    concrete and realistic as possible, and the investigators should test 
    for and present evidence that the results are not sensitive to 
    extraneous design decisions. The commenters stated that the elicitation 
    format should be designed to prevent interviewer bias and protest 
    valuation. Some of these commenters stated that the experimental design 
    should be consistent with accepted design standards. The commenter 
    noted that the applications should include at least two different 
    elicitation formats, and should perform sensitivity analysis on the 
    effects of format choice. The commenters suggested that the attributes 
    used in the survey should reflect: characteristics of the natural 
    resource that are salient to the responder, temporal nature of lost 
    services, and restoration alternatives that are technically feasible. 
    The commenters also stated that the estimation of results should be 
    consistent with utility theoretic principles. The commenter noted that 
    the study should include a description of commodities that serve as 
    substitutes for the lost and replacement services and that the relevant 
    population to be sampled should be limited to users of the same type of 
    services or to individuals sufficiently familiar with the natural 
    resource to be able to form preferences for the relevant services. 
    Commenters also stated that, if the conjoint analysis includes a price 
    term, the following standards should be added: the conjoint analysis 
    should not be used to measure nonuse values; trustees should 
    empirically demonstrate that respondents have considered their budget 
    constraints; the survey should use a payment vehicle that is 
    appropriate for the type of value to be measured, is credible, 
    incentive-compatible, avoids implied value cuing, and distributes 
    burden of payment equitably; the survey should include design points 
    that test for ``warm glow'' effects; trustees should demonstrate 
    empirically that results are sensitive to scope of lost services; and 
    trustees should determine the extent of the relevant population whose 
    values are to be included and document and justify that determination.
    Benefits Transfer
        Comment: Several commenters stated that the responsible party must 
    be allowed to challenge the merits of valuation studies conducted by 
    the trustees, rather than allowing the trustee to use values derived 
    from some other study.
        Some commenters pointed out that the benefits transfer approach 
    should not be accepted uncritically. Other commenters, however, argued 
    for more flexibility in the use of the procedure.
        Several commenters stated that studies to be used in the benefits 
    transfer approach should address natural resources and services similar 
    to those injured by the incident, should be scientifically sound, 
    should use reliable valuation procedures, and should not attempt to 
    measure passive use values, since no reliable studies have been 
    conducted to date.
        Response: NOAA believes that the standards set forth in Sec. 990.27 
    are sufficient to allow trustees and responsible parties to determine 
    the acceptability of a particular assessment procedure for a given 
    incident. NOAA supports the use of all of the procedures discussed in 
    Appendix B of the preamble as reliable and valid within the appropriate 
    context and when performed in accordance with accepted professional 
    practices. NOAA does not believe that the rule should set forth 
    specific standards regarding the implementation of individual 
    procedures, as it is not feasible to prescribe all valid uses of these 
    procedures. The validity and reliability of procedures will depend on 
    the circumstances of particular incidents. However, NOAA is considering 
    the development of a separate guidance document addressing issues 
    pertaining to the use of the procedures discussed above to scale 
    restoration actions under the resource-to-resource or service-to-
    service and valuation scaling approaches.
        Thus, NOAA believes that most of the comments received, which 
    relate to potential problems with certain applications of these 
    procedures, will be dealt with in the context of specific incidents. If 
    procedures do not meet the standards listed in the rule they are not 
    acceptable procedures to use pursuant to this rule. In addition, 
    responsible parties have the option to request alternative procedures 
    that meet the requirements of the rule, if they do not accept the 
    trustees' judgment that a procedure is reliable for the circumstances 
    of an incident.
        In response to some common concerns expressed relative to all 
    
    [[Page 471]]
        procedures, NOAA offers the following: (1) Trustees must make a 
    determination that procedures are reliable and valid for the 
    circumstances of an incident; (2) there must be no double recovery of 
    damages for the same injury or loss; (3) only public losses are 
    recoverable by trustees under this rule; (4) primary restoration only 
    recovers to baseline or comparable conditions or levels; and (5) the 
    rule requires that the most cost-effective of equally appropriate 
    procedures be used.
    
    Subpart C--Definitions
    
    Section 990.30--Definitions
    
    General
        NOAA has revised certain definitions in the rule to ensure that 
    these definitions conform with those that are explicitly defined in 
    OPA.
        Comment: Many commenters made reference to various terms used in 
    the proposed rule considered to be vague and likely to hamper 
    expeditious restoration if they are not defined. These terms include: 
    ``observable;'' ``measurable;'' ``adverse;'' ``impairment;'' ``nexus;'' 
    ``reliable;'' ``valid;'' ``comparable;'' ``equivalent;'' ``same;'' 
    ``similar;'' ``scarcity;'' ``demand;'' ``scale;'' ``scaling;'' and 
    ``substantial threat.''
        Response: NOAA intends that the majority of these terms have their 
    ordinary and customary meaning for purposes of this rule, but offers 
    the following clarification. ``Reliable'' and ``valid'' refer to 
    technical judgments by experts in a particular field that a procedure 
    is consistent with best practices for the measure being investigated 
    under the circumstances. ``Equivalent'' and ``comparable,'' as applied 
    to acquiring natural resources or services other than those injured or 
    lost, have the meaning used in the legislative history of OPA-natural 
    resources that can enhance the recovery, productivity, and survival of 
    the ecosystem affected by a discharge, preferably in proximity to the 
    affected area. (H.R. (Conf.) Rep. No. 101-653, 101st Cong., 2d Sess. at 
    109 (1990).) ``Demand'' has the meaning used in section 1013 of OPA (33 
    U.S.C. 2712), encompassing presenting a claim for damages, based upon a 
    plan for restoration of injured natural resources and services, to a 
    responsible party for payment or implementation. ``Substantial threat'' 
    will be determined by response entities on a case-by-case basis. 
    Finally, ``scale'' and ``scaling'' refer to the size or extent, and 
    procedures to determine appropriate size, of injuries or restoration 
    actions.
        Comment: Many other commenters felt that NOAA should reinsert some 
    of the terms, which were included in the January 1994 proposed rule but 
    were left out in the current proposed rule, or add new terms. These 
    terms include: ``damages;'' ``emergency restoration;'' ``interim 
    restoration;'' ``ecological services or natural resources of special 
    importance;'' ``passive use;'' ``commercial and productive services;'' 
    ``recreational services;'' ``services of natural resources of special 
    significance'' ; and ``Regional Restoration Plan.''
        Response: NOAA has incorporated the statutory definition of 
    ``damages'' into the rule and has expanded the discussion of emergency 
    restoration and Regional Restoration Plans in the preamble. NOAA has 
    also expanded the discussion of ``services'' and ``value'' and does not 
    believe that detailed discussion of various specific types of natural 
    resource services is necessary.
    Baseline
        Comment: A few commenters stated that the definition of 
    ``baseline'' is too restrictive, while others felt that the definition 
    is too flexible. Commenters on both sides stated that NOAA should 
    provide additional clarification. Some commenters argued that 
    ``baseline'' should not be so strictly applied as to prohibit use of 
    information collected reliably but on an intermittent or short-term 
    basis, if it provides a valuable comparison. These commenters suggested 
    that trustees should be allowed to make comparisons against reference, 
    historical, or control conditions. Another commenter stated that 
    baseline data must provide a reliable estimate of variability in the 
    natural resources and services of interest, and that historical or 
    reference data may not be adequate. The commenter pointed out that, in 
    the absence of reliable data on variability, there cannot be a 
    ``baseline,'' however, there can be a ``basepoint'' or ``reference 
    point.''
        Response: Baseline under this rule is used to determine the extent 
    of natural resource injury such that the appropriate scale of 
    restoration actions can be determined. NOAA has simplified the 
    definition of ``baseline'' to encompass the use of ``control,'' 
    ``historical'' and ``reference'' data. Trustees and responsible parties 
    may use any data, so long as that data are reliable (e.g., 
    appropriately collected) and relevant (e.g., collected sufficiently 
    recently) to the incident such that a ``baseline'' can be determined. 
    In terms of assessing baseline, procedures should be chosen to meet the 
    standards contained in the rule, including expected costs and expected 
    increases in the quality of the estimate of baseline conditions.
        Comment: One commenter suggested that NOAA change the definition of 
    ``baseline'' to read: ``Baseline means the condition of the natural 
    resource and/or service that would exist had the incident not 
    occurred.'' The commenter noted that, since baseline is not static over 
    time, defining the term in past tense could be misleading or 
    misinterpreted.
        Response: Natural resources or services may only be restored to 
    their expected current condition or level had the incident not 
    occurred. It may not be appropriate to interpret baseline solely with 
    reference to the condition of the natural resources at the time of the 
    incident for all injuries or losses, although that condition may well 
    be valuable evidence of the baseline.
        Comment: Several commenters insisted that baseline, like injury and 
    restoration, may only be assessed with respect to natural resource 
    services, and more specifically, services used directly by the public, 
    as opposed to the condition of the natural resources themselves.
        Response: OPA is very clear that injury and restoration apply to 
    natural resources themselves. Further, restoration of injured natural 
    resources is one element of a claim for damages, distinct from the 
    diminution in value of injured natural resources suffered by the public 
    from the time of an injury until recovery.
    Contributing Factor
        Comment: One commenter expressed concern that the term 
    ``contributing factor,'' present in the 1994 proposed rule, is absent 
    in the reproposed rule. Other commenters supported omission of a 
    discussion of this concept from the rule, although these commenters 
    differed in their view as to whether a more or a less rigorous standard 
    should be applied by reviewing courts.
        Response: Under the new structure of the rule, NOAA does not 
    believe that a discussion of this concept is needed.
    Cost-effective
        Comment: A number of commenters emphasized that Congress intended 
    that assessments be cost-effective, but suggested there are no 
    meaningful restraints on the number, extent, or cost of damage 
    assessment activities that trustees may implement under the rule.
        Response: NOAA agrees that assessments, as well as restoration, 
    must be cost-effective, and believes the definition indicates that the 
    least costly of several procedures accomplishing the same goals with 
    outcomes of similar 
    
    [[Page 472]]
    quality must be selected by trustees. NOAA suggests that the extent of 
    assessment actions and costs are appropriately limited under both OPA 
    and this rule through the reasonable cost requirement, the standards 
    for acceptable procedures in Sec. 990.27 of the rule, and the pervasive 
    requirement to focus activities on determining needed restoration.
    Discharge
        Comment: Some commenters requested clarification of the definition 
    of ``discharge.''
        Response: In response to comments, NOAA has replaced the previous 
    definition of ``discharge'' with the statutory definition.
    Exposure
        Comment: One commenter suggested that exposure should be defined to 
    mean the presence of any detectable amount of the discharged oil, 
    including oil sheen. Several other commenters recommended that exposure 
    be defined as in 43 CFR Sec. 11.14(q), when natural resources ``may 
    be'' in contact with oil, rather than requiring actual evidence of 
    exposure.
        Response: For the purposes of this rule, exposure refers to direct 
    or indirect contact with oil. A sheen does indicate that the surface 
    water natural resource has been exposed, which may affect services 
    provided, such as boating.
    Incident
        Comment: Some commenters suggested that the definition of 
    ``incident'' should be replaced with the statutory definition.
        Response: NOAA has replaced the previous definition of ``incident'' 
    with the statutory definition.
    Injury
        Comment: A number of commenters noted that the definition of injury 
    is an improvement from that of the January 1994 proposed rule and that 
    of the CERCLA rule's definition, in that it is simpler, easier to 
    apply, and includes adverse impacts that might be excluded under the 
    CERCLA rule delimiting specific categories of injury.
        In contrast, other commenters argued that the definition of injury 
    is insufficient because it applies to natural resources themselves, 
    rather than strictly to services provided by natural resources, and 
    does not incorporate the concept of baseline. Some of these commenters 
    suggested that the definition allows the mere presence of a contaminant 
    in water to be an injury. These commenters suggested that NOAA redefine 
    injury as ``(a) an observable or measurable adverse change in a natural 
    resource that produces a quantifiable reduction in the level of 
    services provided by that natural resource, or (b) an observable or 
    measurable impairment of a natural resource service,'' further 
    specifying that ``such change and/or impairment must be measured 
    relative to baseline.''
        According to these commenters, although the physical, chemical, and 
    biological characteristics of a natural resource contribute to the type 
    and level of services it offers, the public does not value those 
    characteristics in and of themselves, it values only the services the 
    natural resource provides. Thus, the commenters argued that, if a 
    change in a natural resource does not affect such services, it cannot 
    constitute a compensable injury. The commenters stated that, to the 
    extent that trustees obtain compensation for harm to the environment as 
    something separate from the services provided to the public, society 
    would be overcompensated for its loss. Further, these commenters 
    suggested that compensable natural resource service losses be 
    restricted to those of ``measurable ecological significance'' (effects 
    are manifested at the population, community or ecosystem level) and/or 
    those used directly by the public.
        In addition, the commenters suggested that failure to include 
    reference to baseline in the definition of injury will allow trustees 
    to measure adverse changes relative to pristine, pre-industrial levels.
        Response: NOAA believes that OPA clearly intends that injuries to 
    natural resources themselves form the primary focus of trustees' 
    restoration actions. This intent is evident in the definition of 
    liability under the statute (``injury to, destruction of, loss of, or 
    loss of use of natural resources''), as well as the measure of damages 
    under the statute which provides an explicit distinction between 
    liability for injuries to natural resources (costs to restore) and 
    liability for interim lost services (diminution in value). Adoption of 
    the commenters' approach to assessment and restoration would severely 
    undercompensate the public for injuries suffered as a result of an 
    incident and would result in a needless sacrifice of natural resources 
    that could otherwise be cost-effectively restored. The only way to 
    ensure that all valuable present and future services of natural 
    resources are available to the public is to restore the injured natural 
    resources to their pre-incident condition. The rule requires trustees 
    to quantify injuries relative to baseline, which is defined as the 
    without-the-incident condition of the natural resources. This 
    requirement clearly prevents assumption of a ``pre-industrial'' 
    baseline. NOAA does not believe that the concept of baseline has useful 
    meaning in defining injury, as opposed to quantifying injury. Finally, 
    because the rule requires a measurable or observable adverse change in 
    a natural resource or service be documented in addition to exposure, 
    the ``mere presence'' of oil will not constitute an injury under the 
    rule.
        Comment: One commenter suggested that an existing state regulatory 
    definition of injury be adopted to allow for consistent natural 
    resource damage assessment within the state.
        Response: NOAA believes that the definition of injury in the rule 
    is consistent with the intent of OPA to facilitate expeditious, 
    necessary, and cost-effective restoration.
        Comment: Some commenters suggested the terms ``measurable'' and 
    ``observable'' inappropriately allow injury to be determined using 
    simplified procedures, notably the type A model or compensation 
    formulas, which assume that injury always occurs from the presence of 
    oil in the environment. Other commenters suggested that NOAA clarify 
    that models that predict expected injuries based on past data are 
    encompassed within the definition of injury.
        Response: The commenters are referred to the procedures for 
    determining injury in Sec. 900.51 of the rule. The definition of injury 
    must be met, and exposure and a pathway must be documented to determine 
    injury. Any procedure used to document injury, exposure, and pathway 
    must meet the standards enumerated in new Sec. 990.27 of the rule, 
    which seeks to ensure that the most technically appropriate procedure 
    for the circumstances of an incident and an injury be used to make 
    injury determinations, including those for exposure and pathway.
        Comment: One commenter suggested that the injury definition be 
    broadened to include habitat degradation.
        Response: NOAA believes that OPA and the rule do apply to habitat 
    degradation caused by incidents, so long as the requirements of the 
    rule for determining injury are met.
    Oil
        Comment: A few commenters agreed that animal fats and vegetable 
    oils are covered by OPA's definition of oil, but asserted that their 
    limited capacity to cause harm in the environment should exempt them 
    from coverage by this rule, or provide for a separate assessment 
    process specifically tailored to these 
    
    [[Page 473]]
    different products. The commenters argued that Executive Order No. 
    12,866 on Regulatory Planning and Review requires that differential 
    treatment be afforded these products. Other commenters similarly 
    requested clarification as to whether natural or synthetic gas 
    products, or coal tar and other coal-derived chemicals are classified 
    as oil for purposes of the rule.
        Response: NOAA notes that the commenters do recognize the capacity 
    for animal fats and vegetable oils to cause natural resource injury if 
    they are released in significant quantities. These products are 
    included in the definition of oil under the NCP. NOAA believes that the 
    rule's Preassessment Phase requirement that trustees assess the 
    likelihood of natural resource injuries resulting from a discharge, 
    along with the requirement that injury actually be determined prior to 
    quantification, will provide appropriate safeguards for nonharmful 
    products discharged into the environment. The preamble advises trustees 
    that the nature of the product discharged (e.g., differences in 
    physical, chemical, biological, and other properties, and environmental 
    effects) should be evaluated in the trustee's Preassessment Phase. As 
    to synthetic gas and coal-derived chemicals, substances that have been 
    classified as hazardous substances are clearly not covered by this 
    rule, but by the CERCLA rule.
    Pathway
        Comment: One commenter stated that the definition of ``pathway'' is 
    somewhat vague in the use of the term ``nexus.''
        Response: NOAA has replaced the term ``nexus'' with ``link,'' to 
    refer to the required connection between an incident and a natural 
    resource or service of concern.
    Person
        Comment: Several commenters suggested that the definition of 
    ``person'' should be modified to include agencies of the federal 
    government.
        Response: NOAA notes that the rule definition is consistent with 
    the statutory definition.
    Reasonable Assessment Costs
        Comment: One commenter noted that the costs of conducting 
    assessments represent unanticipated financial burdens on trustee 
    agencies, so the rule should include provisions that require 
    responsible parties to reimburse trustees for all legitimate expenses 
    associated with incidents covered by the rule. Several commenters 
    suggested that oversight costs for responsible party participation and/
    or implementation of any assessment activities should be explicitly 
    recoverable. While several commenters supported inclusion of 
    administrative, legal, and enforcement costs in the definition, others 
    strongly opposed this as outside NOAA's statutory authority. These 
    commenters pointed to rulings prohibiting recovery of court costs in 
    CERCLA cost recovery actions, and suggested that damage assessment 
    costs necessarily cease at the point monetary damages are determined 
    for a claim. Some commenters stated that duplicate assessment costs 
    incurred as a result of trustees' failure to coordinate their efforts 
    should be explicitly excluded from recovery.
        Response: OPA defines damages as the costs of restoration, plus the 
    reasonable cost of assessing those damages. Thus, damages encompasses 
    whatever actions are reasonable and lawful under OPA to implement 
    restoration, clearly including administrative, legal, and enforcement 
    costs, as well as monitoring and oversight costs. OPA's requirement for 
    public involvement in developing a restoration plan to form the basis 
    of a claim for damages presented to a responsible party likewise makes 
    the reasonable costs of facilitating public participation recoverable. 
    OPA prohibits double recovery of damages, including assessment costs. 
    However, NOAA does not believe that an inference of double assessment 
    costs should be drawn solely from the fact that two or more trustees 
    are assessing damages independently. The reasonableness of damage 
    assessment costs must be evaluated relative to the specific injury for 
    which a restoration action is being considered.
        Comment: With respect to incremental costs and benefits, one 
    commenter suggested that the phrase ``reasonably related'' is vague and 
    subjective and should be modified. Another commenter stated that 
    reasonable costs should include ``expected'' before ``incremental 
    cost'' and ``incremental increase.'' Some commenters interpreted the 
    proposed rule to require a strict cost-benefit analysis in selecting 
    any assessment procedures. One commenter suggested that the definition 
    of ``reasonable assessment costs'' should not use word ``reasonably'' 
    to define ``reasonable.'' One commenter suggested that the reasonable 
    cost definition should return to the 1994 proposed language of 
    ``reasonable under the circumstances, but only if in accordance with 
    the rule.''
        Response: NOAA agrees that the 1995 proposed definition of 
    reasonable costs was somewhat vague. NOAA also believes that the 
    element of the reasonable cost definition in the proposed rule, 
    requiring incremental costs and benefits to be evaluated, is 
    duplicative of the analysis trustees must make in selecting all 
    assessment procedures used under this rule, as provided in the new 
    Sec. 990.27. Thus, this element has been deleted from the definition. 
    The new provision in Sec. 990.27 of the rule does not require a strict 
    cost-benefit analysis of assessment procedures, as this would result in 
    unreasonable assessment costs. Rather the costs and benefits analysis 
    is intended to constrain the scope and scale of assessments to fit the 
    circumstances of individual incidents and injuries.
        Comment: Several commenters suggested that assessment costs should 
    be strictly proportional to damages, with some suggesting that costs 
    must not exceed damages to be reasonable, consistent with the CERCLA 
    rule. Another commenter stated that assessment costs should be 
    proportionate to the value of the restoration action, rather than the 
    cost of that action. Other commenters suggested that reasonable costs 
    must be related to the severity of an incident. Several commenters were 
    troubled by allowing recovery of assessment costs where restoration is 
    not pursued.
        Response: NOAA agrees that trustees should determine an appropriate 
    relationship between assessment costs and the costs of restoration and 
    compensation sought as a result of the incident. However, NOAA does not 
    believe that a strict proportion, or a cost ceiling equal to total 
    damages or total value, is appropriate for all cases. There may be 
    instances where assessment costs to determine appropriate restoration 
    are necessarily high due to unique sampling or testing requirements, 
    yet high costs would be justifiable given the importance of undertaking 
    restoration--for instance, where an endangered species population has 
    been injured. The rule places strict limits on instances where trustees 
    can recover assessment costs if they do not pursue restoration. 
    Trustees must have made, in good faith, all determinations required in 
    the rule and proceeded in the assessment with a reasonable expectation 
    that injury had occurred and restoration was needed.
        Comment: One commenter stated that reasonable assessment costs 
    should only include those costs associated with an assessment made at 
    the site of the incident, not any assessment costs incurred at regional 
    restoration sites. Other commenters argued that trustee costs of NEPA 
    compliance and production of an administrative record 
    
    [[Page 474]]
    should not be recoverable, pointing to the CERCLA rule's omission of 
    these procedural requirements.
        Response: Reasonable assessment costs include costs associated with 
    evaluating restoration alternatives and selecting an equally preferred 
    approach for an incident. Costs associated with identifying and 
    evaluating existing regional restoration plans or other existing 
    proposed restoration projects among a range of alternatives to restore 
    injuries resulting from an incident are reasonable costs under the 
    rule. In addition, NOAA believes that maintenance of an administrative 
    record will be a cost-effective mechanism of keeping the public and 
    responsible parties informed of the progress and results of an 
    assessment, and judges these costs to be reasonable costs of 
    assessment. Similarly, because NEPA compliance is an existing statutory 
    requirement applicable to restoration actions by federal trustees, 
    these compliance costs are recoverable, just as any permitting 
    requirements would be recoverable in implementing restoration under 
    OPA.
    Recovery
        Comment: Several commenters argued that a focus on recovery of 
    natural resources themselves, as opposed to services is counter to 
    OPA's mandate. Other commenters suggested that baseline be explicitly 
    incorporated within the definition of recovery, to ensure that the 
    proper focus is the ``without an incident'' condition.
        Response: As discussed under the definition of injury above, the 
    condition of natural resources themselves may lawfully be assessed in 
    identifying and quantifying injuries. NOAA does not believe that 
    baseline needs to be redefined in the definition of recovery, but 
    agrees that recovery refers to the condition the natural resources and 
    services would have been had the incident not occurred.
    Responsible Party
        Comment: Some commenters requested revisions to the 1994 proposal's 
    definition of ``responsible party'' to conform with the statutory 
    definition.
        Response: NOAA has replaced the definition of responsible party 
    with the statutory definition.
    Restoration
        Comment: Most commenters were satisfied with the definition of 
    restoration as encompassing all authorized actions under the statute 
    (restoration, rehabilitation, replacement, acquisition of the 
    equivalent), without setting a preference for any of the statutory 
    alternatives. Other commenters, however, felt that the rule limited 
    trustee discretion in requiring consideration of restoration measures 
    over acquisition measures.
        Response: The rule does not require that restoration, 
    rehabilitation, or replacement be considered before acquisition of 
    equivalent natural resources. Acquisition of the equivalent is a viable 
    option and includes actions that would enhance the recovery, 
    productivity, and survival of the ecosystem affected by a discharge, 
    preferably in proximity to the affected area.
        Comment: Several commenters suggested that the distinction between 
    ``primary'' and ``compensatory'' restoration needs clarification. Some 
    of the commenters suggested that primary restoration should include any 
    action, whether on-site, off-site, in-kind, or out-of-kind, that will 
    return natural resource and/or service levels back to baseline 
    condition. These commenters supported defining compensatory restoration 
    as actions to make the environment and public whole for interim losses 
    resulting from the incident.
        Some commenters stated that the proposed rule could be interpreted 
    to limit primary restoration to actions focused on the injured natural 
    resources themselves. These commenters stated that relegating 
    replacement or acquisition alternatives that use other natural 
    resources solely to compensatory restoration is inconsistent with 
    section 1006(d)(1)(A) of OPA (33 U.S.C. 2706(d)(1)(A)), which 
    prescribes replacement and acquisition of the equivalent as measures of 
    ``primary restoration.''
        Response: NOAA intends that primary restoration actions encompass 
    all actions authorized under section 1006(d)(1)(A) of OPA (33 U.S.C. 
    2706(d)(1)(A)), while compensatory restoration includes actions to 
    compensate for the diminution in value of injured natural resources or 
    services pending their recovery (section 1006(d)(1)(B) of OPA (33 
    U.S.C. 2706(d)(1)(B)). NOAA does not believe that OPA contains any 
    explicit preference for a specific type of restoration, or whether it 
    be accomplished on or off-site and has revised the rule. Because 
    damages recovered for diminution in value must be spent solely to 
    restore, rehabilitate, replace, or acquire the equivalent of the 
    interim natural resource injuries, trustees should assess damages for 
    diminution in value in terms of these types of actions. NOAA has 
    amended the rule to reflect these considerations.
        Comment: Several commenters asserted that NOAA has improperly 
    broadened potential recovery for diminution in value by dressing it up 
    as compensatory restoration, and defining these actions as those to 
    make the environment whole, in addition to making the public whole. 
    These commenters argued that compensatory restoration may only replace 
    interim lost service flows to the public.
        Response: The diminution in value of natural resources may be 
    measured by a number of metrics, such as dollars or quanta of services 
    lost. If no restoration actions are taken, or recovery with active 
    restoration may still require a number of years, many types of services 
    may be lost or diminished in the interim period, including ecological 
    services, and OPA does not intend that only certain types of lost 
    services be compensated. Diminution in value under the rule still 
    appropriately encompasses interim lost services pending recovery and 
    has not been broadened. The rule requires that trustees determine 
    restoration actions to compensate for these losses rather than monetize 
    the claim.
        Comment: A number of commenters asked for or offered additional 
    clarification on the distinction between ``natural recovery'' and ``no 
    action.'' Several commenters requested that NOAA delete the no action 
    alternative. Several commenters strongly disagreed with classifying 
    natural recovery as restoration, while several others appreciated the 
    explicit requirement to consider natural recovery, which they expect 
    will often provide the most cost-effective mechanism to return natural 
    resources to baseline. One of the commenters noted that there should be 
    a requirement that restoration only be undertaken if it significantly 
    accelerates natural recovery. Finally, some commenters remarked on the 
    difficulty and expense likely to be incurred to estimate the time 
    required for natural recovery.
        Response: NOAA has deleted the ``no action'' alternative from the 
    final rule, as it was confusing in the context of evaluating 
    restoration alternatives at the stage that injury and the need for 
    restoration have been determined. The final rule will continue to 
    require that natural recovery be evaluated as one of a range of primary 
    restoration actions--actions intended to return injured natural 
    resources and services to baseline conditions. The rule already 
    requires trustees to assess the relative capability of each restoration 
    alternative to accelerate recovery, so it is not necessary to add a 
    requirement that a restoration alternative significantly 
    
    [[Page 475]]
    accelerate recovery relative to natural recovery. Finally, the rule 
    requires that procedures to estimate natural recovery be evaluated 
    according to the standards governing acceptability of any other 
    assessment procedure, including the cost of alternative procedures 
    relative to expected informational benefits for the circumstances of a 
    particular incident. Thus, the rule allows that natural recovery may be 
    estimated qualitatively or quantitatively. The rule also provides a 
    number of factors as guidance in estimating natural recovery timelines.
    Services
        Comment: Many comments on the definition of services discussed the 
    distinctions between ``ecological'' and ``human'' services. One 
    commenter stated that the definition appropriately encompasses both 
    concepts, but that the term ``public services'' is overly restrictive. 
    By using the term ``public'' services, the commenter suggested that 
    NOAA may inadvertently preclude recovery for lost services that benefit 
    many individuals but not the general public. To address this problem, 
    the commenter urged NOAA to use the term ``human services'' rather than 
    ``public services'' throughout its final rule.
        A number of commenters argued that the proposed definition of 
    compensable services is faulty in including functions performed by one 
    natural resource for another. These commenters suggested that 
    ecological services are only compensable to the extent they provide 
    services of value to the public, because ecosystem functions do not 
    have economic value unless they help to support service flows to 
    people.
        These commenters further suggested that the proposed definition 
    exceeds the scope of NOAA's authority since OPA does not authorize 
    trustees to assess damages on behalf of non-human things or beings. The 
    commenters noted that the measure of damages under OPA refers to losses 
    to the public, since it is only people who have values for natural 
    resource services. The commenters pointed out that the legislative 
    history of OPA also makes it clear that ``diminution in value'' refers 
    to the lost use value standard for measuring natural resource damages 
    used in the Ohio decision (880 F.2d at 462-480)(H.R. (Conf.) Rep. No. 
    101-653, 101st Cong., 2d Sess. 108 (1990)), which made it apparent that 
    the lost use value standard related to lost values to the public. 
    Further, the commenters stated that the CERCLA rule on remand from Ohio 
    specifies that compensable value means the value of ``services lost to 
    the public.'' 43 CFR 11.80(b).
        Response: Humans and other species in the ecosystem are 
    inextricably linked; consequently, ecological services are generally 
    linked to human services. Trustees may not double-count public losses 
    attributable to injured natural resources by seeking compensation both 
    for human losses and for the ecological services that will return the 
    same direct human services. However, in some cases it may be much more 
    cost-effective to focus on the ecological services that occur on-site 
    rather than the human services that occur off-site as a result of these 
    ecological interactions. For example, a wetland habitat may provide on-
    site ecological services such as faunal food and shelter, sediment 
    stabilization, nutrient cycling, and primary productivity. Off-site 
    human services may include commercial and recreational fishing, bird 
    watching along the flyway, water quality improvements for drinking 
    water supply or the aesthetics of nearby residential property, and 
    storm protection for on-shore properties due to the creation of wave 
    breaks.
         Consequently, the inclusion of ecosystem services is consistent 
    with OPA. However, trustees must ensure that they do not seek 
    compensation both for human losses and for the ecological services that 
    will return the same direct human services, which would create a double 
    recovery.
        Comment: Many commenters asserted that the concept of baseline 
    should be built into the definition of compensable services. These 
    commenters suggested that baseline measures of use services should 
    incorporate relevant site-specific factors that influence demand for 
    the services and should reflect established committed uses rather than 
    speculative levels of use. The commenters stated that NOAA should 
    include the CERCLA's rule definition and requirement of ``committed 
    use'' in its rule, which is defined as either ``a current public use; 
    or a planned public use for which there is a documented legal, 
    administrative, budgetary, or financial commitment before the discharge 
    of oil or release of a hazardous substance'' (43 CFR 11.14).
        Response: NOAA does not believe that baseline must be incorporated 
    into the definition of services, given the requirement to quantify 
    services injuries relative to baseline. NOAA agrees with the commenters 
    that speculative future uses of natural resources are not compensable 
    under OPA and that this limitation is inherent in the requirement that 
    trustees determine the existence of injury or service injuries before 
    quantifying restoration requirements.
        Comment: Several commenters suggested that the definition of 
    ``services'' should explicitly include both ``direct and passive 
    uses.'' Some of these commenters also requested that NOAA include 
    examples of passive services in the definition.
        Response: NOAA agrees that compensable services include both direct 
    and passive uses, and that the rule provides for recovery of both.
    Value
        Comment: A number of commenters supported the definition of 
    ``value'' as proposed. However, other commenters suggested that this 
    definition is vague, and needs to be refined. One commenter suggested 
    that the definition of ``total values'' in the rule and the discussion 
    in the preamble are not consistent. Another commenter did not 
    understand what the ``units'' represent in the definition, with another 
    commenter suggesting that OPA restricts compensation to dollars. A few 
    commenters indicated that NOAA should replace the word ``good'' with 
    goods or services, as people value both goods and services. One 
    commenter suggested that NOAA change the last sentence to read: ``The 
    total value of a natural resource and/or service is equal to the sum of 
    all values held by an individual across all individuals.''
        Finally, a few commenters argued that passive values should be 
    excluded because they cannot be reliably measured. The commenters 
    suggested that NOAA's silence results in an equal treatment of use and 
    nonuse values; implicitly allowing for the calculation of nonuse values 
    using contingent valuation without any specific standards.
        Response: NOAA does not believe that OPA restricts measuring lost 
    value solely in terms of dollars, and has amended the rule to allow for 
    computation in terms of goods, services, or money.
    
    Subpart D--Preassessment Phase
    
    Section 990.40--Purpose
    
        Comment: Several commenters felt that the proposed new language on 
    preassessment is a significant improvement over the January 1994 
    proposal. These commenters stated that the new Preassessment Phase 
    achieves the necessary goals of this early stage of an assessment, 
    which is to cost-effectively and timely determine whether injuries to 
    natural resources have likely occurred such that further trustee action 
    on behalf of the public is warranted.
        A few general concerns, however, were expressed by one commenter. 
    This 
    
    [[Page 476]]
    commenter was under the impression that preassessment activities 
    require identification (as reflected by the qualifier ``observable'') 
    and quantification (as reflected by the qualifier ``measurable'') of 
    injury. The commenter noted that observing adverse changes is typically 
    less difficult than measuring actual or approximate losses, suggesting 
    that this portion of the rule not be so narrow as to require precise 
    measurement of degradation in situations where a loss has been 
    observed. To facilitate more effective mitigative strategies, the 
    commenter suggested preassessment activities be segregated into 
    analyses of impacts to aquatic organisms and habitat.
        The same commenter further stated that the costs of conducting 
    preassessment activities may represent unanticipated financial burdens 
    on trustees. The commenter suggested the rule include provisions that 
    require responsible parties to reimburse trustees for all legitimate 
    expenses associated with incidents covered by the rule.
        Response: The purpose of Preassessment Phase activities is to 
    determine whether it is legitimate for trustees to take action under 
    this rule for purposes of OPA, and whether it is reasonable to do so, 
    given their responsibilities to act on behalf of the public to see that 
    injured natural resources and services are restored. At this stage of 
    an assessment, actual determination and quantification of injury are 
    not required. Costs should not necessarily be great at this phase of an 
    assessment, depending on the circumstances of an incident and resulting 
    injuries, and trustees are encouraged to contain costs by limiting the 
    amount of data collection and analysis conducted, and to coordinate 
    early with response agencies and responsible parties to prevent 
    duplicative efforts.
    
    Section 990.41--Determination of Jurisdiction
    
        Comment: One commenter stated that the notification language is too 
    weak and that the OSC or lead response agency should be required to 
    notify natural resource trustees. This commenter indicated that the OSC 
    or lead response agency should not only consult with the affected 
    trustees concerning removal actions, but should also consult with 
    affected trustees concerning protection strategies.
        Response: NOAA notes that coordination between the OSC and trustees 
    is covered in section 1011 of OPA (33 U.S.C. 2711) and in the NCP. The 
    duties of the OSC, including coordination, are covered by other 
    rulemakings, not this rule.
    Excluded Discharges
        Comment: One commenter suggested that the language in this part 
    should be modified to exclude only those discharges that are in 
    compliance with a permit under federal, state or local law. The 
    commenter pointed out that discharges that exceed permitted limits 
    should not receive an exemption from natural resource damages liability 
    simply because they emanate from a permitted discharge point.
        Another commenter remarked that tribal permits should also be 
    included within this language.
        Response: The language of the rule copies the statutory language on 
    excluded discharges, including the reference to permits under local 
    law. NOAA interprets the phrase ``permitted by a permit'' to mean that 
    only discharges that are authorized by, and thus in compliance with, 
    the terms of a permit are eligible for the exclusion.
        Comment: One commenter noted that public vessels are used as an 
    example of exclusion from liability and suggested it would be helpful 
    for the preamble to reiterate that exclusion in addition to the 
    permitted discharge exclusion. Another commenter questioned why onshore 
    facilities subject to the Trans-Alaska Pipeline Authority Act (TAAPA), 
    43 U.S.C. 1651 et seq., are exempt from liability.
        Response: NOAA has amended the preamble to include the citation to 
    the OPA sections providing for the excluded discharges and notes that 
    the TAAPA facility exclusion is provided by OPA.
        Comment: Another commenter noted that the Oil Spill Liability Trust 
    Fund cannot be accessed to initiate assessments for incidents 
    originating from a federal facility. The commenter asked what 
    mechanisms exist that would allow for restoration given this situation.
        Response: NOAA notes that trustee agencies may be called upon to 
    carry out restoration out of agency budgets where there are no other 
    funding sources available.
    Injured Natural Resources or Services
        Comment: Several commenters stated that the rule necessitates 
    identification and notification of all trustees in order to determine 
    whose trust natural resources may be injured, which is crucial to 
    coordination among trustees.
        One commenter indicated that the rule should clearly state that all 
    physical, on-site trustee activities, including data collection and 
    analysis, occurring concurrently with removal efforts are subject to 
    the approval and overall direction of the OSC. The commenter stated 
    that the rule should also require effective coordination between 
    natural resource trustees and participants in the incident response, 
    consistent with the NCP (40 C.F.R. Sec. 300.305(e), 50 FR 47384, 47445 
    (Sept. 15, 1994)).
        Response: NOAA agrees that coordination among all affected trustees 
    is extremely important, especially during Preassessment Phase 
    activities. The requirements for coordination are enumerated in 
    Sec. 900.14 of the rule rather than in individual subparts, to 
    emphasize that the duty to coordinate is applicable to the entire 
    assessment. NOAA does not believe that an explicit requirement to 
    identify and contact other trustees should be included in the rule. 
    Trustees need maximum flexibility during the often hectic response 
    phase to ensure that, among other things, ephemeral data is collected. 
    NOAA notes that identification and contact among trustees virtually 
    always occurs during the response phase, if for no other reason than 
    requests for initiation funding from the Oil Spill Liability Trust Fund 
    require such coordination.
        The requirement to coordinate with the OSC is also included in 
    Sec. 990.14. Although NOAA agrees and the rule reflects that trustees 
    activities may not interfere with response activities, NOAA disagrees 
    that any requirement exists, nor should it exist, that the OSC must 
    approve all trustee activities. Many of these activities are far 
    outside the realm of authority or interest of the OSCs.
    Decision to Proceed
        Comment: One commenter indicated that injury determination should 
    be a precondition to trustee jurisdiction. The commenter pointed out 
    that restoration under OPA is, by definition, wholly retrospective, and 
    does not extend to measures designed to prevent or contain ``threatened 
    discharges.'' The commenter stated that the injury determination in 
    Sec. 990.51 should be satisfied in the Preassessment Phase before the 
    restoration planning process begins.
        Response: NOAA disagrees with the comment. Injury determination is 
    properly part of the formal assessment, and is not required during the 
    Preassessment Phase. Determination of injury at this point may result 
    in unreasonable assessment costs without some sort of screening process 
    provided in this phase. 
    
    [[Page 477]]
    
    
    Section 990.42--Determination to Conduct Restoration Planning.
    
    Considerations
        Comment: One commenter suggested that the conditions in this part 
    are subjective and require more specific guidance. However, another 
    commenter was concerned about being required to complete some of the 
    determinations at such an early stage in the process when it may be 
    particularly difficult to determine whether response actions will 
    adequately address injuries.
        Response: There is necessarily a subjective component in trustees 
    applying their best professional judgment to existing or readily 
    available information in order to make the determinations in this 
    section. NOAA believes that this balance of judgment and data analysis 
    is most appropriate and cost-effective at this stage of an incident.
        Comment: A number of commenters indicated that the responsible 
    parties should be included (and officially notified) in the 
    determination to conduct restoration planning. The commenters 
    questioned whether the administrative record will be open during this 
    stage, and whether all data used to make a determination to conduct 
    restoration planning will be made available to responsible parties.
        Response: The rule provides that identified responsible parties be 
    notified and invited to participate in the assessment as soon as 
    practicable, but no later than the point that trustees decide to 
    conduct restoration planning and prepare a public notice to that 
    effect. Participating responsible parties will be provided documents 
    detailing the determinations that are required under the rule. The rule 
    also indicates that the administrative record should be opened 
    concurrently with issuing the Notice of Intent to Conduct Restoration 
    Planning. The record is available to responsible parties as well as any 
    other member of the public.
        Comment: Another commenter noted that the need for restoration is 
    based on an evaluation of whether response actions will alleviate the 
    residual injuries. The commenter suggested that the rule should clarify 
    that both residual injuries and direct, initial injuries are to be 
    considered at this point.
        Another commenter suggested that it may also be difficult to 
    determine whether feasible restoration alternatives exist when the 
    trustees do not yet know the full extent of the injuries. A number of 
    commenters were concerned that the notion of ``feasible'' might be 
    narrowly interpreted to mean ``on-site/in-kind,'' in which case 
    restoration may not be possible. One of these commenters suggested that 
    the rule allow both primary and/or compensatory restoration actions 
    that might be considered.
        Response: NOAA agrees that all injuries occurring from the time of 
    the initial or threatened discharge should be considered in evaluating 
    the efficacy of response actions in alleviating the need for 
    restoration. Response actions may be effective in restoring some 
    injuries caused by the initial incident, for instance by removing oil 
    from a sandy beach so that the beach can be reopened. While this 
    response action may restore a natural resource service to baseline, it 
    would not compensate for the interim lost use that occurred during the 
    closure period. The rule has also been amended to indicate that 
    feasible primary or compensatory restoration actions should be assessed 
    in making the determination to proceed with restoration planning.
    Decision to Proceed
        Comment: Several commenters supported the provision authorizing 
    trustees to recover reasonable assessment costs incurred up to the 
    point that preassessment determinations are made. However, one 
    commenter notes that it is thus incumbent upon the trustees to limit 
    their assessment costs. The commenter suggested that prompt decisions 
    by the trustees on jurisdiction and the need for restoration will 
    ensure that costs are contained, and eliminate the possibility for 
    responsible parties to delay completion of response measures until such 
    trustee determinations are made. The commenter thus recommended 
    trustees be required to make both determinations within ninety (90) 
    days of an incident.
        Response: The rule provides that all reasonable costs of assessment 
    are recoverable, including those costs incurred up to the point 
    trustees decide not to pursue restoration. Costs must meet the rule's 
    definition of ``reasonable assessment costs'' to be recoverable. NOAA 
    disagrees with the need for or utility of a ninety-day limit on making 
    the determination to conduct restoration planning, and doubts that fear 
    of this determination will cause responsible parties to drag out costly 
    response activities. NOAA believes that any time limit would be 
    arbitrary, given the great variability in the progress and timing of 
    cleanup activities from incident to incident.
    
    Section 990.43--Data Collection
    
        Comment: One commenter questioned how the determinations in 
    Sec. 990.42 are to be made based upon ``readily available 
    information.'' The commenter suggested this limitation is acceptable if 
    it includes all the sources listed in this section. One commenter also 
    suggested the term ``limited'' in the proposed rule may imply that if 
    trustees went too far in data collection, they might not be entitled to 
    the rebuttable presumption and/or costs for that data collection 
    because they might not be considered ``reasonable.'' A few commenters 
    stated that, so long as the data to be collected is reasonably related 
    to the assessment, no other restrictions should be placed on its 
    collection. In contrast, one commenter noted that there are no controls 
    specified in this part over the expense or timing of preassessment data 
    collection activities.
        Response: The rule has been amended to specify that data collection 
    and analysis that are reasonably related to the purposes of the 
    Preassessment Phase may be conducted in accordance with the rule. The 
    rule provides guidance on the types of information that may be useful 
    in making Preassessment Phase determinations. The term ``limited'' has 
    been removed from the rule, but was originally intended to suggest that 
    data collection should be related to the determinations required to be 
    made at this stage, and thus to the nature of the incident and its 
    injuries, and the relevance and utility of available information.
        Comment: Another commenter suggested that trustees should be able 
    to use models or extrapolations from scientific literature when it is 
    more appropriate and cost effective than gathering site-specific data.
        Response: NOAA notes that the type of analysis suggested by the 
    commenter is exactly the type of reliance upon existing information 
    that this section intends to be available to trustees, if such 
    information is relevant to the incident.
    
    Section 990.44--Notice of Intent to Conduct Restoration Planning
    
        Comment: Several commenters suggested that the rule should 
    explicitly acknowledge the need for flexibility in completing the 
    Preassessment Phase. The commenters noted that, since incidents vary 
    greatly in scope, the effort invested by trustees should be 
    proportional to the magnitude of the incident, therefore, the rule 
    should allow the public notice and participation steps to be 
    compressed, when appropriate. Other commenters pointed out that the 
    proposed language requires trustees to prepare a public notice, even if 
    they have declined to proceed with an assessment. Another commenter 
    suggested that trustees 
    
    [[Page 478]]
    should be required to provide the specific authority for which the 
    trustees are asserting a potential claim in the Notice.
        Response: NOAA believes that the rule does direct trustees to 
    tailor their preassessment activities to the nature and extent of an 
    incident, given the determinations that this section requires trustees 
    to make. Section 990.14(d) has been amended to explicitly provide that 
    the degree, extent, and timing of public participation prior to 
    development of a draft restoration plan is within the discretion of the 
    trustees. The final rule also indicates that the manner of making the 
    Notice of Intent to Conduct Restoration Planning publicly available 
    will depend on the nature and extent of the incident. The final rule 
    also explicitly requires that the notice reference the specific 
    authority under which trustees are pursuing a claim for restoration of 
    their trust natural resources.
        Comment: One commenter suggested that notice requirements to the 
    responsible party, and required contents of the notice, are unclear. 
    Another commenter noted the requirements to prepare a notice and open 
    the administrative record should be moved to a later point in the 
    assessment, so that such requirements will not hamper necessary 
    trustees activities.
        Response: NOAA has amended the rule to indicate that a written copy 
    of the notice must be sent to identified responsible parties, and the 
    rule at Sec. 990.44 now specifies information for inclusion in the 
    notice. The rule provides trustees the flexibility to conduct essential 
    Preassessment Phase activities that will allow them to make the 
    requisite determination that they should proceed with restoration prior 
    to turning their efforts to preparing a Notice of Intent to Perform 
    Restoration Planning and opening an administrative record.
    
    Section 990.45--Administrative Record
    
    Review on the Record
        Comment: Several commenters argued that the rule should not be 
    silent on the standard of review for assessments, but should 
    emphatically, specifically, and clearly state that the standard of 
    review applicable to trustee decisions, based upon an administrative 
    record, is like that of any other ``final agency action'' contemplated 
    under the Administrative Procedure Act (5 U.S.C. 551-59, 701-06), or 
    applicable State or tribal counterparts. Some of these commenters 
    suggested that because OPA authorizes NOAA to provide for the 
    administrative adjudication of damages (33 U.S.C. 2706 (c)-(e)), the 
    promulgation of a rule providing for such administrative adjudication 
    would ensure that OPA's restoration goals are met. These commenters 
    also objected to NOAA's failure to provide for procedures to 
    administratively adjudicate natural resource damages that should, in 
    particular, provide for a hearing to be held by a neutral arbitrator 
    when requested as the statute requires.
        Several commenters noted that, if NOAA is wrong about the effect of 
    the rule, then following the rule will severely prejudice the trustees. 
    The commenters stated that, if responsible parties are successful in 
    conducting ``shadow'' assessments and convincing courts that they are 
    entitled to trials de novo, then the public will be ill-served by 
    trustees complying with the rule. The commenters pointed out that, 
    unlike the responsible parties, trustees will be forced to reveal their 
    claim, data, procedures, and analyses in an open process and losing any 
    litigation privileges on their scientific information, which will put 
    trustees at a distinct disadvantage in litigation compared to 
    responsible parties. The commenters also noted that protections are 
    necessary so that a breakdown of a cooperative process, in which 
    information has been shared, does not undermine the ability of trustees 
    to make recoveries and complete restoration.
        Several commenters described the expected benefits of review on the 
    administrative record process, including greatly reduced amounts of 
    litigation, and associated transaction costs, greater public 
    participation in damage assessment and restoration decisions, and 
    enabling trustee agencies to make decisions on natural resource damage 
    assessments and restoration plans within their areas of expertise, 
    instead of having courts decide extremely complex technical, 
    scientific, and economic determinations. Other commenters stated that 
    record review would be beneficial to the responsible party, who will be 
    able to contest any trustee decisions from a neutral, common body of 
    data which they may help to develop.
        Other commenters argued that the Seventh Amendment to the U.S. 
    Constitution, which guarantees a jury trial in suits at common law, 
    does not preclude record review of the damage determination, stating 
    that the Supreme Court has interpreted this language as applying to 
    actions analogous to those brought in 18th-century English courts of 
    law as opposed to courts of equity or admiralty. The commenters argued 
    that a claim for damages to natural resources is much more analogous to 
    an equitable action than a legal one. Some commenters stated that 
    record review is also mandated by the rebuttable presumption since it 
    would make no sense for there to be such a presumption absent record 
    review. The commenter noted that the rebuttable presumption is based on 
    the existence of a full record and careful administrative decisions.
        Other commenters addressed other statutory processes that grant 
    record review to comparable regulatory processes, such as NEPA. The 
    commenters pointed out that, although the cases are not directly on 
    point, a few courts have applied a deferential standard of review to 
    decisions of state or local agencies made pursuant to NEPA. One 
    commenter specifically stated that NOAA should not try to imply that 
    NEPA compliance is intended to or construed as an indirect means of 
    attaining deferential review on record.
        Some commenters suggested that the rule now creates a negative 
    inference regarding applicability of record review by retreating from 
    its earlier, wholly defensible position. The commenters stated that 
    NOAA need not make the standard of review mandatory in the rule, but 
    should express its legal opinion in the preamble regarding record 
    review based on the ``arbitrary and capricious'' standard.
        Several commenters endorsed the decision not to expressly address 
    in the rule a standard of judicial review, but the commenters argued 
    that legal and policy considerations dictate that NOAA should not imply 
    such a standard either. The commenters noted that simply changing 
    ``compensable values'' to ``compensatory restoration'' is not enough to 
    bring such components under a presumed preferential standard of review. 
    The commenters argued that, since this element remains based on the 
    same statutory provision for ``diminution in value,'' it would still be 
    subject to de novo review.
        One commenter noted that the rule provides so little meaningful 
    restraint on trustee discretion, the unfairness of a record review 
    approach is patent.
        Response: NOAA agrees that damage assessment determinations made 
    pursuant to OPA constitute final agency actions typically subject to 
    review on the record by federal courts, and fully expects that this is 
    the standard of review that will be applied. NOAA agrees with the 
    benefits and rationales discussed in support of record review, and also 
    agrees that the rebuttable presumption is not inconsistent with review 
    on the record. NOAA does not agree that diminution in value 
    
    [[Page 479]]
    necessarily provides for de novo review by a court, given that this is 
    but one element of a claim for damages, all of which must be applied to 
    restoration. NOAA does not believe that many responsible parties are 
    interested in conducting ``shadow'' assessments.
        However, NOAA does not believe that it is within the scope of 
    responsibility tasked to NOAA to promulgate natural resource damage 
    assessment regulations to specify reviewing court procedures and 
    protocols. No negative inference should be drawn from lack of 
    declaration within the rule that review on the record is the expected 
    standard of review.
        Comment: Some commenters noted that preparation of an 
    administrative record need not significantly delay the assessment or 
    ``overwhelm'' trustees in conducting assessments. The commenter stated 
    that it is usually rather simple and straightforward for the trustee 
    contemporaneously to organize all documentation supporting its 
    decisions into an administrative record, and that such preparation will 
    save tremendous time and resources in preparing for a record review 
    trial, although not necessarily for a trial de novo.
        Some commenters stated that the responsible party should be 
    required to meet the same public disclosure standards as the trustees, 
    to whatever extent they are involved in the assessment. These 
    commenters noted that public involvement is made more meaningful and 
    restoration plans are more properly suited to the injury as more data 
    is available, and the availability of data also removes the uncertainty 
    of litigation as well. One commenter expressed concern that the use of 
    the record will compromise trustees' litigation, with no corresponding 
    risk for the responsible party. Some commenters noted that sharing 
    information may be an enticement to responsible parties to join 
    trustees in an assessment; this incentive would not exist if the 
    trustee is required to reveal information in the record in any case.
        Response: NOAA agrees that preparation of an administrative record 
    need not delay the assessment. Past experience has indicated that 
    secretive assessments are not in the best interests of the public or 
    the natural resources. It is in all parties' interests to openly and 
    cooperatively determine what restoration actions are needed as a result 
    of an incident, so that restoration can be implemented quickly. NOAA 
    believes that delayed restoration defeats the purposes of OPA. NOAA 
    does not believe that responsible parties are likely to gain any 
    advantage by not participating equally and openly in preparation of the 
    administrative record, and expects a reviewing court would view with 
    disfavor the withholding of information to spring upon the trustees at 
    the eve of trial.
    Contents of the Record
        Comment: One commenter asked for clarification as to what types of 
    documents should be included in the administrative record.
        Response: NOAA points out that federal trustees should maintain the 
    administrative record, including what documents might be included in 
    administrative record, in manner consistent with the Administrative 
    Procedure Act. Trustees should be guided by an understanding that all 
    documents relied upon in making ultimate determinations about 
    restoration should be included in the record.
        Comment: Some commenters expressed concern that third party 
    litigants would use the information in the record to advance private 
    claims. One commenter suggested that attempts by third parties to 
    obtain information from the record would delay the restoration process. 
    Another commenter noted that the kind of information in the record, 
    focused on restoration, may not be particularly helpful to third party 
    litigants.
        Response: It is not uncommon that private parties use publicly 
    available information obtained from governments to support their 
    private claims. Information gathered during an assessment on behalf of 
    the public should not be withheld from the public. NOAA does not expect 
    that allowing public access to an administrative record will result in 
    delays in restoration.
    
    Subpart E--Restoration Planning Phase
    
    Section 990.51--Injury assessment
    
    Causation
        Comment: Some commenters stated that the proposed rule does not 
    clearly require trustees to use sound and reliable science, or provide 
    specific requirements to be met in the various steps of the injury 
    assessment. Several commenters stated that the rule must include 
    rigorous standards and criteria for determining that an observed injury 
    was caused by an incident to avoid unsupported, unnecessary, and 
    unreasonable claims. One commenter noted that if the damage assessment 
    is used for evidence collection, the question of how the data will be 
    used raises a question of the level of confidence.
        Response: The treatment of injury determination within the rule 
    supports the use of sound and reliable science to demonstrate that 
    injuries identified have resulted from the incident. This treatment 
    embodies the principles and practices of natural resource damage 
    assessments developed over the past several years.
        Comment: Several commenters raised concerns regarding demonstrating 
    causation for injuries resulting from response actions or a substantial 
    threat of a discharge. These commenters noted that trustees must still 
    show clear and specific causation for those injuries resulting from the 
    response or threat, not from some other cause. Other commenters also 
    stated that the rule should clarify that injury assessment is not 
    limited solely to addressing injury residual to response actions, but 
    should include direct, initial injuries.
        Response: For injuries resulting from an actual discharge, trustees 
    must evaluate exposure and pathway and demonstrate that injury resulted 
    from the incident. For injuries resulting from a response action or a 
    substantial threat of a discharge, trustees must also demonstrate that 
    the injury occurred because of the incident. Under this rule, 
    assessments are not limited solely to addressing injuries residual to 
    response actions, but include the direct, initial injuries. Evidence 
    supporting the linkage between the incident and injury must be 
    established to demonstrate injury. The rule's requirement to quantify 
    injuries relative to baseline may provide the proof of causation.
        Comment: One commenter requested that the rule state that an 
    incident should be deemed the cause of an injury if the incident was a 
    contributing factor to an indivisible injury, as provided in the 1994 
    proposal.
        Response: NOAA does not believe it is appropriate to advocate legal 
    standards of causation in the rule. Injuries must be determined to have 
    occurred, then quantified relative to baseline, to be in accordance 
    with the rule.
    Injury Determination
    General
        Comment: Several commenters stated that the exceedance of some 
    threshold or criterion by itself should not constitute an injury unless 
    it can be shown to be relevant to each phase of injury determination, 
    have population, habitat, or ecosystem level effects, or directly 
    affect the human population. The commenters noted that the rule 
    
    [[Page 480]]
    should require injury determination and quantification for such 
    injuries unless there are special circumstances such as threatened or 
    endangered species.
        Response: NOAA disagrees that the suggested limitations on the 
    definition of injury are appropriate or warranted given OPA's mandate 
    to make the environment and public whole. If an injury resulting from 
    an incident can be cost-effectively and reliably determined and 
    quantified, and feasible, cost-effective, environmentally-beneficial 
    restoration actions can be identified, then restoration should be 
    pursued. However, NOAA does not suggest that each and every injury, 
    regardless of its nature and scale, should be pursued in an assessment. 
    Trustees proceed with an assessment when the information on injury is 
    adequate to justify restoration.
        Comment: Some commenters suggested that the acceptance criteria in 
    the CERCLA rule for injuries should be adopted in this rule. Other 
    commenters did not understand the need for acceptance criteria, which 
    were viewed as too restrictive and narrow. Another commenter 
    specifically asked that the rule make the assessment consistent with 
    the Archaeological Resources Protection Act (ARPA), 16 U.S.C. 1361 et 
    seq., or at least incorporate the ARPA criteria.
        Response: The rule does not list specific acceptance criteria for 
    injuries per se. The rule does, however, include factors aimed at 
    achieving meaningful restoration. NOAA believes that the rule is 
    adaptable and will allow trustees to select the injuries and assessment 
    procedures that will provide reliable and valid information to 
    determining appropriate restoration. Thus, the assessment process 
    described in the rule should be flexible enough to incorporate the 
    concerns and goals of ARPA.
    Demonstrating Exposure and Pathway
        Comment: Several commenters argued that allowing demonstration of 
    exposure and pathway by procedures other than field procedures would 
    allow trustees to claim injury without leaving their desks. The 
    commenters stated that the rule should require trustees to show 
    evidence of actual exposure and a pathway. Another commenter, however, 
    suggested that trustees might use procedures other than those used in 
    the field to demonstrate exposure and a pathway, if environmental 
    conditions or other assumptions are comparable between the proposed 
    procedures and the actual field conditions. Some commenters suggested 
    that the phrase ``plausible pathway'' be changed to ``reasonably likely 
    pathway.''
        Response: Like any other assessment procedure used under this rule, 
    procedures to determine exposure and pathway must meet the standards 
    for acceptable procedures in Sec. 990.27. Thus, the most appropriate 
    procedure for the circumstances will be selected by trustees, and NOAA 
    does not believe that any of the suggested limitations or qualifiers 
    are necessary in the rule.
    Focus on Services
        Comment: Many commenters argued that injury assessment should focus 
    on the services provided by a natural resource rather than simply the 
    natural resource's physical, chemical, or biological properties. The 
    commenters noted that, given that ecosystems need some level of 
    disturbance to maintain biological diversity, and the difficulty in 
    determining recoverability of natural resources since natural resource 
    stability does not exist, adverse effects to natural resources that 
    cannot be linked to services provided to the public or the overall 
    functioning of the population, community, or ecosystem ought not be 
    considered under the rule.
        Response: OPA states that trustees ``shall assess natural resource 
    damages'' (section 1006(c)) and that these damages are ``for injury to, 
    destruction of, loss of, or loss of use of, natural resources'' 
    (section 1002(b)(2)(A)). The language of OPA clearly does not indicate 
    a preference for services over natural resources.
        On a practical basis, the determination of recovery is possible, as 
    demonstrated by the wealth of information on this topic in the 
    literature and summarized on NOAA's restoration guidance document, 
    listed in the Bibliography at the end of the preamble. Ecological 
    concepts such as stability, although not static, can also be reasonably 
    determined and thus used to define recovery. This is also supported by 
    the literature. Thus, contrary to the commenter's position, NOAA 
    maintains that recovery of natural resources, as a practical matter, 
    can and must be considered in order to fulfill OPA's goal of making the 
    environment and public whole.
    Panel of Experts
        Comment: Some commenters suggested that NOAA establish a team of 
    experts in ecology to provide a better scientific basis for determining 
    and quantifying injury to natural resources. These commenters also had 
    specific concerns with the use of certain procedures, e.g., biomarkers, 
    and the manner of accounting for indirect effects.
        Response: NOAA does not believe it is necessary at this time to 
    convene a panel of experts. Instead, the standards for procedures 
    provided in Sec. 990.27 should address the concerns about certain 
    procedures on a case-by-case basis.
    Types of Injuries
        Comment: Several commenters suggested that the rule include a list 
    of pre-accepted biological and non-biological injuries and parameters 
    such as reproductive success and juvenile or adult survival. The 
    commenters stated that the rule should also provide a mechanism to 
    modify the list of accepted injuries as new information becomes 
    available. These same commenters stated that, whether or not such a 
    list is finalized, the rule should allow an injury to be determined 
    based on a discharge, known concentrations, and literature 
    documentation that such substances in such amounts injure certain 
    natural resources. One commenter suggested the rule implies that 
    trustees will assess injuries that do not meet some unarticulated 
    threshold. The commenter stated that the decision to select injuries 
    for assessment should be left to the discretion of the trustees.
        Response: The rule does provide that it is within the discretion of 
    trustees to select subsets or representative injuries and parameters 
    from the suite of injuries and parameters to include in the injury 
    assessment and restoration planning. Rather than specify discrete 
    categories for limiting this scope, e.g., recreational importance, the 
    rule encourages a focus on accomplishing meaningful restoration by 
    identifying factors to consider in selecting injuries to include in the 
    assessment. The guidance document on injury provides information on the 
    types of injuries that may result from incidents involving oil.
    Framework for Assessment
        Comment: One commenter indicated that the rule should provide a 
    framework that is interpretable to all trustees. The commenter 
    suggested that the ecological risk assessment procedure would greatly 
    facilitate the assessment.
        Response: NOAA believes that the rule does provide a 
    comprehensible, logical, and straightforward assessment procedural 
    framework. The general logic of ecological risk assessment is reflected 
    in the assessment process in the rule. However, NOAA does not believe 
    that the approach typically involved in risk assessment is appropriate 
    for all, or even most, incidents. 
    
    [[Page 481]]
    
    Injury Procedures
        Comment: One commenter stated that the rule should more clearly 
    state that both quantitative and qualitative procedures may be used in 
    an injury assessment.
        Response: Both quantitative and qualitative procedures are 
    available to trustees under this rule. This flexibility is made clear 
    in the discussion of the standards for acceptable procedures in 
    Sec. 990.27 and in the definition of injury in Sec. 990.30.
    Proceeding With the Assessment
        Comment: One commenter stated that the rule requires that all of 
    the listed criteria for determining injury must be met before trustees 
    may proceed with an assessment. The commenter noted that it might not 
    be feasible to have documented all the criteria at this point, thus the 
    rule should simply require that trustees ``consider'' these criteria 
    before proceeding with restoration planning.
        Response: The conditions in the rule are intended to encourage a 
    focus on necessary and meaningful restoration. Therefore, proceeding 
    with an assessment at this stage is contingent upon demonstrating 
    injury.
    Public Involvement
        Comment: Some commenters argued that there should be greater public 
    involvement in the injury determination, quantification, and 
    restoration process so that the public will be allowed to participate 
    in the selection of injuries to be included in the assessment. The 
    commenter noted that the public may be aware of injuries of which the 
    responsible party and trustees are unaware. The commenters stated that, 
    if the public input is to be meaningful and comply with OPA, the public 
    must be given a formal means of involvement throughout the process.
        Response: The rule acknowledges the value of involving the public 
    in the assessment, and requires that trustees provide opportunities for 
    public involvement after making the decision to develop restoration 
    plans. Additional opportunities may be provided at any time prior to 
    this decision if such involvement facilitates the decisionmaking 
    process or helps to avoid delays in restoration.
    
    Section 990.52--Quantification
    
    Baseline
        Comment: Some commenters stated that the rule does not require 
    quantification relative to baseline. Commenters noted a number of 
    difficulties associated with determining baseline for quantification 
    purposes including the use of historical data that may not reflect 
    current conditions at the site of the assessment and the need to 
    account for natural variability or confounding influences to adequately 
    compensate for injuries without overestimating the injuries. The 
    commenters also pointed out that non-equilibrium systems are the rule, 
    so baseline may be difficult to define, let alone achieve. Finally, the 
    commenters also noted that funding is rarely if ever available for 
    establishing baseline.
        Some commenters argued that quantification should focus on services 
    rather than natural resources, therefore baseline should be defined as 
    the flow of services to the public that would have existed in the 
    absence of the incident.
        Response: The approach for quantification does relate injury to 
    baseline. The rule acknowledges the inherent difficulties in collecting 
    traditional baseline data and has been expanded to encompass other 
    appropriate types of data for comparison. Broadening the concept of 
    baseline will allow trustees to more appropriately adapt the 
    quantification approaches to the circumstances of an incident. NOAA 
    also notes that strict reliance on services is neither explicitly 
    stated nor implied under OPA. Thus, the definition of baseline and its 
    application to quantification is retained in the rule.
    Quantification Approaches
        Comment: A number of commenters argued that the rule should require 
    quantification of the reduction in services resulting from the 
    incident, as required in the CERCLA rule. Some of the commenters stated 
    that the dichotomy of measuring the change in the natural resource 
    itself, or directly in the services is unnecessary and that only the 
    measurement of reduced services can serve as a predicate for 
    compensable natural resource damages. Some commenters argued that NOAA 
    should adopt acceptance criteria for injury quantification, such as: 
    service reductions must be linked to the discharge and the natural 
    resource injury; service reductions must be measured relative to 
    baseline; service reductions must be measured in terms of functions 
    provided by the injured natural resources, not the physical quantities 
    or qualities of the natural resources; and measurements of service 
    reductions must account for the presence and availability of substitute 
    services.
        Response: The rule allows trustees to assess the injured natural 
    resources directly and/or directly assess the lost services provided by 
    injured natural resources. NOAA believes that narrow restrictions on 
    assessing services to humans will fall far short of fulfilling the 
    intent of OPA to make the environment and public whole. NOAA believes 
    that the public does value and benefit from productive, functional, and 
    healthy natural resources, habitats, and ecosystems. Neglecting OPA's 
    mandate to restore that which was injured and substituting natural 
    resources on a narrow cost and human use basis would result in real 
    degradation of the natural resources. Establishing additional 
    quantification criteria focusing on human services would be 
    inappropriate.
    Scale of Injury
        Comment: One commenter stated that quantification should be limited 
    to only those injuries necessary, and only to the degree necessary, to 
    develop appropriate restoration measures. Some commenters pointed out 
    that a consideration of the extent of injuries should not be restricted 
    to the physical boundaries of the incident, particularly where natural 
    resources at risk are highly mobile and seasonal in their 
    distributions.
        Response: Quantification is appropriate where injury has been 
    determined to have resulted from the incident. Where information on 
    injury provided by quantification procedures is adequate to justify 
    restoration, then restoration actions should be pursued. Also, under 
    the rule, the spatial and temporal extent of injury is not restricted 
    to the physical boundaries of the incident and trustees may consider 
    the particular characteristics of a natural resource, including its 
    mobility, in quantifying injury.
    Committed Services
        Comment: Some commenters requested that the rule allow reduction in 
    service flows only for established or ``committed'' services to avoid 
    speculative recoveries.
        Response: The provisions in the rule relating to quantification of 
    services lost relative to baseline ensure that speculative recoveries 
    are avoided.
    Injury Quantification Procedures
        Comment: One commenter stated that the rule should call for field-
    based quantification procedures, including a set of general and basic 
    standards for quantifying reductions in services. Other commenters 
    requested that the rule provide trustees with the ability to choose one 
    or any combination of quantification procedures, so long as there is no 
    double recovery.
        Response: NOAA does not believe that the rule should prescribe 
    limited or 
    
    [[Page 482]]
    specific procedures for quantifying injury, as it is infeasible to 
    determine the universe of procedures that would be appropriate for all 
    incidents. Such a limitation would prevent trustees from using the most 
    appropriate procedure for the circumstances of the incident, and would 
    likely prevent use or adaptation of procedures to provide 
    quantification information that is useful in restoration scaling. 
    Instead, the rule provides standards in Sec. 990.27 for use in 
    determining appropriate procedures. The rule does allow trustees to use 
    a combination of the suggested quantification approaches, but prohibits 
    trustees from applying injury quantification procedures in a manner 
    that would result in double recovery.
    Substitutes
        Comment: One commenter argued that the rule fails to require 
    consideration of substitutes when injury is defined in terms of a 
    reduced population as opposed to a broad enough category to incorporate 
    substitution.
        Response: Substitution is not explicitly identified as a factor in 
    quantifying injuries because it is only relevant to a subset of 
    injuries or losses--those that relate to value flowing from behavioral 
    opportunities available to humans.
    Natural Recovery
        Comment: Several commenters stated that the requirement for 
    estimating the time for natural recovery may be difficult to meet, and 
    that the rule should instead call for this estimate when such estimate 
    is readily available and cost-effective, and when no primary 
    restoration is likely to be effective.
        Response: NOAA acknowledges the difficulty in estimating natural 
    recovery and has provided the necessary flexibility to trustees. The 
    rule has been amended to provide that recovery may be estimated 
    quantitatively or qualitatively, depending on the circumstances of the 
    incident and procedures available that meet the standards for 
    procedures under Sec. 990.27.
    
    Section 990.53  Restoration Selection--Developing Restoration 
    Alternatives
    
    General
        Comment: Many commenters supported the shift in focus from 
    monetization of damages to scaling of restoration actions. These 
    commenters stated that the proposed rule properly places the focus of 
    the damage assessment on the ultimate goal of OPA to restore injured 
    natural resources and services, and incorporates best current practices 
    currently being used by trustees and responsible parties to achieve 
    this goal in an expeditious manner. However, many other commenters 
    raised concerns that the scaling approach would lead to delays and 
    increased assessment costs, since trustees would undertake studies of 
    lost services and replacement services, and would not substantially 
    further the goal of reducing transaction costs. Other commenters 
    suggested that requiring trustees to quantify all damages in terms of 
    specific restoration actions and costs places trustees in the position 
    of either settling for compensation for immediately apparent, short-
    term losses or delaying the restoration process while waiting for long-
    term injuries to become apparent. One commenter noted that the public 
    will not be served in either case; therefore, trustees should be 
    allowed to recover damages, then determine the most appropriate 
    restoration approach over time. Another commenter argued that as 
    accurate assessment becomes more difficult and costly, less scientific 
    rigor will be required.
        Response: Trustees are required, under section 1006(c) of OPA (33 
    U.S.C. 2706(c)), to ``develop and implement a plan for the restoration, 
    rehabilitation, replacement, or acquisition of the equivalent, of the 
    natural resources under their trusteeship.'' By permitting a variety of 
    possible restoration activities, this section of OPA leaves to the 
    trustees' discretion the determination of the most appropriate 
    activity, recognizing the legislative history's indicated preference 
    for restoration over acquisition of equivalent natural resources. All 
    damages recovered must be spent on some restoration activity. Thus, it 
    makes sense that evaluating potential restoration actions provide the 
    focus of an assessment. It does not benefit the natural resources or 
    the public if monies are collected without a view toward how they will 
    be spent, nor whether sufficient funds have been collected to implement 
    any meaningful action. OPA is not about collecting money. NOAA believes 
    that, contrary to some comments, the restoration approach will 
    generally speed restoration and avoid litigation, by alleviating 
    distrust that claims for monetary damages are speculative and punitive. 
    Practical experience in implementing the restoration scaling approach 
    in past cooperative assessments has led NOAA to the belief that this 
    approach is effective in significantly expediting the restoration of 
    injured natural resources and services, and that the benefits to the 
    environment and public do not come at the expense of increased 
    assessment costs. While trustees now must assess replacement services 
    in addition to lost services in most incidents, NOAA believes that, in 
    general, a net increase in assessment costs will not result, due to 
    both the cooperative provisions set forth within this rule and the 
    removal of the requirement that trustees estimate the monetary value of 
    damages. NOAA also believes that the standards for assessment 
    procedures set forth in Sec. 990.27(a) of the rule will ensure a 
    sufficient level of rigor for all assessments.
    Range of Alternatives
        Comment: Some commenters requested guidance on what might be an 
    appropriate range of restoration alternatives. Other commenters noted, 
    however, that the rule should not require the development and 
    consideration of a predetermined number of potentially unreasonable 
    alternatives.
        Response: NOAA does not agree with the commenters who recommended a 
    limit on the range of alternatives trustees should consider. Trustees 
    should consider a range of alternatives that is reasonable for the 
    incident of concern, and the specific natural resources injured. The 
    rule requires that only actions that are feasible and legal be 
    considered. The range of feasible actions may vary greatly, depending 
    on the types of injuries suffered, or the nature of the environment or 
    habitat, among other things. Guidance on the types of actions and how 
    they might be considered is provided in the Restoration Guidance 
    Document, referenced in the Bibliography at the end of this preamble.
    Natural Recovery Alternative
        Comment: Some commenters suggested that, when injuries are not 
    extensive or are short-term, no restoration actions are needed, 
    therefore, the rule should more strongly require consideration of 
    natural recovery. Many commenters supported the requirement that 
    trustees always consider natural recovery as an option. Several 
    commenters stated that the rule should adopt a preference for natural 
    recovery.
        Other commenters stated that the language regarding the ``no 
    action'' alternative is confusing. Another commenter suggested that the 
    confusion over the terms might be a result of the different objectives 
    of OPA and NEPA.
        Several commenters stated that the rule should set out reasonable 
    
    [[Page 483]]
        expectations for analysis of natural recovery, especially where 
    injuries are evident from the Preassessment Phase investigations and 
    feasible restoration alternatives exist. These commenters suggested 
    either deleting the requirement to evaluate a no action alternative or 
    making it optional.
        Response: The rule requires that natural recovery be evaluated as a 
    primary restoration action in every case. ``No action'' refers to 
    alternatives in which trustees take no primary restoration action and 
    no compensatory restoration actions. Natural recovery, which must be 
    considered for each incident, is only considered under the primary 
    restoration component of the alternative and only refers to direct 
    restoration involving no human intervention. Trustees have the 
    discretion to choose any combination of primary and/or compensatory 
    restoration actions, given the circumstances of the incident.
    Primary Restoration
        Comment: Many commenters requested that the rule clarify the 
    distinction or relationship between primary and compensatory 
    restoration. Another commenter, however, suggested that this was a 
    distinction without any significance. Some commenters interpreted the 
    regulations to allow only on-site, in-kind actions in primary 
    restoration. Some commenters noted that, if the rule is interpreted to 
    limit primary restoration to actions focused on the injured natural 
    resources themselves, and to relegate replacement or acquisition 
    actions solely to compensatory restoration, it is inconsistent with 
    OPA, which authorizes replacement and acquisition of the equivalent as 
    measures for primary restoration. Other commenters noted that primary 
    restoration could include any action, whether on-site, off-site, in-
    kind, out-of-kind, that returns natural resource and/or service levels 
    back to baseline condition.
        Response: NOAA has sought to clarify the distinction between 
    primary and compensatory restoration, including specifying explicitly 
    in the preamble discussion of the definition of ``restoration'' that 
    primary restoration may include on-site, off-site, in-kind, and/or out-
    of-kind restoration actions that return injured natural resources and 
    services to baseline. Actions to restore, replace, rehabilitate, or 
    acquire the equivalent of injured natural resources or services may be 
    considered in evaluating both primary and compensatory restoration 
    actions.
        Comment: Some commenters suggested that primary restoration should 
    attempt to make the public whole by returning net services to the 
    public to baseline.
        Response: NOAA believes that in most cases, primary restoration 
    alone will not be sufficient to make the environment and public whole. 
    When incidents result in interim lost services, an additional 
    compensatory restoration component will be necessary to fully 
    compensate for injuries to trust natural resources.
        Comment: One commenter stated that the rule should require a 
    hierarchy of alternatives, such as on-site, in-kind; off-site, in-kind; 
    and off-site, with substitute natural resources or services with 
    equivalent economic value.
        Response: NOAA does not support the development of such a 
    hierarchy, since it may prevent the trustees from selecting and 
    implementing the alternative which best meets the criteria for 
    evaluation of alternatives presented in Sec. 990.54(a).
    Acquisition of the Equivalent
        Comment: One commenter contended that acquisition of the equivalent 
    is inconsistent with the stated aim of compensatory awards and should 
    not be considered. The commenter questioned how acquiring the 
    equivalent restores the injured natural resources, since the effects of 
    most incidents are transient. Some commenters on the 1994 proposal 
    objected to the ranking of restoration alternatives whereby acquisition 
    of the equivalent is the option of last resort, especially where 
    natural resources are subject to development or other pressures (e.g., 
    in urban areas). The commenter stated that trustees should be free to 
    acquire the equivalent even if other restoration alternatives are 
    possible. Some commenters stated that the goal of restoration is to 
    make the public whole through whatever alternatives are available under 
    OPA, which may or may not include returning natural resources to 
    baseline.
        Response: NOAA contends that, in some instances, acquisition of 
    equivalent natural resources or services may be necessary to adequately 
    compensate the environment and public. The present rule does not 
    prevent acquisition of the equivalent even in the presence of other 
    feasible alternatives.
    Restoration of Services
        Comment: Several commenters argued that restoration alternatives 
    must be formulated and evaluated by reference to the services provided 
    by the injured natural resource, not the natural resource itself. 
    Therefore, the commenter suggested that NOAA should make every effort 
    to clarify that the restoration of services of natural resources refers 
    only to those services or functions provided to society. Commenters 
    added that the service-focus is needed to select the most cost-
    effective, rational, and efficient restoration alternatives. The 
    commenters argued that allowing trustees to choose full physical 
    restoration where a less expensive alternative can fully replace the 
    services provided by the natural resource is contrary to the goal of 
    cost-effectiveness since the additional expenditure required for full 
    physical restoration provides no additional benefit to the public. 
    Other commenters suggested that a natural resource-based approach could 
    result in overcompensating the public.
        Response: The rule focuses all assessment decisions on restoration, 
    and making the environment and public whole. Primary restoration 
    focuses on the injured natural resources themselves, as authorized by 
    OPA's language basing liability and damages on injuries to natural 
    resources themselves, while compensatory restoration focuses on the 
    services that are lost as a result of the incident, and which are not 
    compensated for by implementing the primary restoration action. Both 
    elements must be considered in designing restoration alternatives. 
    Because OPA defines damages to include both the cost of restoration and 
    diminution in value, a focus solely on natural resources or solely on 
    services risks undercompensating the environment and the public.
    Other considerations
        Comment: Several commenters suggested that a focus on ``certain key 
    species or habitats'' may lead to controversy, since terms are not 
    defined. The commenters noted that there is sufficient guidance in the 
    quantification section on this issue and that these terms are not 
    needed. However, the commenters suggested that, if the terms are 
    retained, the phrase ``key services'' should be added.
        One commenter suggested that there is the need to develop 
    procedures that allow for non-predictable attributes of the ecosystem. 
    The commenter noted that, for other programs requiring restoration, a 
    poor job has been done in the past of documenting restoration outcomes 
    needed to provide data for development of new models.
        One commenter stated that the procedures for restoration under OPA 
    are unlikely to replace injured natural resources because of inadequate 
    
    
    [[Page 484]]
    knowledge on critical habitat functions, long-term success and the lack 
    of procedures to assess impacts due to multiple stressors.
        Response: The final rule retains the guidance that primary 
    restoration actions that return key natural resources or services to 
    baseline may be an appropriate restoration alternative if, for 
    instance, such an action would facilitate return or recovery of other 
    natural resources. The concept of key services has been added to the 
    rule. NOAA believes that the rule's requirements to determine standards 
    to gauge the success of restoration actions, and performance criteria 
    to measure the progress of actions in achieving goals and success, will 
    provide the types of information through monitoring that the commenters 
    suggest are needed.
    Compensatory Restoration
    Mandatory Inclusion
        Comment: Some commenters argued that the inclusion of compensatory 
    restoration should be required in all planning efforts, and not be 
    discretionary. Some of these commenters stated that if trustees do not 
    include compensatory restoration actions, they should include a written 
    justification for compelling reasons of why such actions were not 
    included.
        Response: The rule and preamble have been revised to reflect that 
    trustees must consider compensatory restoration action and also must 
    document this decision in the restoration plan.
    General
        Comment: Many commenters noted that there are too many undefined 
    terms, e.g., ``scarcity,'' ``comparable,'' ``equivalent,'' used in the 
    compensatory restoration provisions.
        Response: NOAA has amended the rule to require that the relative 
    value of injured and replacement natural resources and services be 
    evaluated, rather than scarcity and demand.
        Comment: Several commenters suggested that the compensatory 
    restoration approach seems to have been structured as an attempt to 
    circumvent the difficulties in accurately measuring interim lost 
    values. However, the commenters stated that the concepts of 
    compensatory restoration and scaling do not address the defects of the 
    1994 proposal and that these concepts are based upon economically and 
    legally unsound assumptions and, therefore, fail to comply with the 
    statutory measure of damages.
        Response: NOAA has put forth the revised rule with the intent of 
    expediting restoration of injured natural resources and services. NOAA 
    believes that the compensatory restoration approach in this rule is 
    technically and legally sound, and consistent with the language and 
    intent of the statute, and more appropriate to adequately assess and 
    compensate for interim losses than previous approaches.
    Concept of Compensatory Restoration
        Comment: Several commenters argued that the concept of compensatory 
    restoration creates the potential for exaggerated or excessive damage 
    awards and will enable excess money to be spent on natural resource 
    projects without limitations. Some of these commenters argued that this 
    approach has insufficient constraints on the application of procedures, 
    which may result in double counting, assessments beyond the scope of 
    OPA, or damages that are grossly disproportionate to the value of the 
    natural resources.
        Response: NOAA believes that the standards provided in the rule for 
    acceptable procedures, the prohibition on double recovery, and the 
    opportunities for public review and input provide constraints 
    sufficient to avoid the problems suggested by the commenters.
    Services Eligible for Compensatory Restoration
        Comment: Some commenters suggested that the rule is unclear as to 
    what types of services would be eligible for compensatory restoration. 
    The commenters stated that the rule should have an additional section 
    that would list protocols that would enable trustees and responsible 
    parties to easily ascertain what service functions were impaired by the 
    incident, if any, and then make rational decisions about what types of 
    projects would serve as adequate restoration.
        Response: NOAA has developed draft guidance documents, listed in 
    the Bibliography at the end of the preamble, that directly address 
    these commenters' concerns. These guidance documents will be finalized 
    after the rule is final. All quantifiable lost services for which 
    feasible restoration actions can be identified are compensable under 
    the rule.
    Components Included Under Compensatory Restoration
        Comment: Some commenters noted that the rule should clarify that 
    compensatory restoration is defined as actions to make the environment 
    and public whole for interim losses. Another commenter noted that 
    compensatory restoration could also address any additional injury 
    associated with the incident. On the other hand, another commenter 
    stated that interim lost values should not be collected by trustees 
    because that would be double recovery, and that collection of these 
    damages should be allowed only if there is a mechanism for distributing 
    those recoveries to the group injured by the incident.
        Some commenters noted that the rule should clarify that 
    compensatory restoration is defined as actions to make the environment 
    and public whole for interim losses. Another commenter noted that 
    compensatory restoration could also address any additional injury 
    associated with the incident.
        Response: In order to make the public whole for the resource 
    injuries, it is not sufficient to ensure that the resources are 
    returned to baseline condition, the public also must be compensated for 
    the losses from the time of the injury until full recovery of the 
    resources. For example, when beaches, parks, or fisheries are closed 
    and natural resource stocks are injured, people either will lose or 
    will have impaired opportunities for fishing, hunting, hiking, 
    birdwatching, and other activities. OPA provides that the measure of 
    damages includes recovery of the costs of restoring natural resources 
    and services to baseline, plus compensation for interim losses (and for 
    assessment costs). These recoveries are not to be distributed to 
    affected groups or individuals, rather OPA requires that they be used 
    to restore, rehabilitate, replace, or acquire the equivalent of the 
    injured natural resources. The recoveries are to be collected and spent 
    on natural resource restoration actions by the public agencies managing 
    the natural resources in trust for the public.
        Private parties also may have standing to claim for private losses 
    resulting from a particular incident. Double recovery is not allowed 
    under statute. Public and private claims are for logically different 
    categories of losses. Specific provisions are articulated in the rule 
    in order to avoid double recoveries.
        Comment: Some commenters stated that the rule should not allow for 
    recovery of any private losses because of the potential for double 
    recovery. These commenters noted that such recoveries would include 
    economic rent, private recreational losses (consumer surplus), lost 
    commercial revenue, and government revenues. One commenter stated that 
    changes in economic rent as a result of an incident are too complicated 
    to estimate reliably because of changes in factor costs and other 
    prices. Another commenter argued that trustees should not be able to 
    collect for economic rent even when private 
    
    [[Page 485]]
    parties do not make such claims because this recovery by trustees is 
    not included within the language of OPA.
        Some commenters noted that the final rule should include the 
    ``multiplier impact'' from interim losses to estimate the true loss. 
    These same commenters also stated that the final rule should consider 
    nationwide, statewide, and regional assessments to account for areas 
    affected outside the direct impact area.
        Another commenter suggested that the final rule should clarify the 
    factors that may weigh into a natural resource damage assessment 
    involving subsistence resources, particularly nutritionally and 
    culturally critical, as well as highly regulated natural resources.
        Response: The preamble discussion of Sec. 990.22 has been revised 
    to provide trustees with detailed guidance in distinguishing between 
    public and private economic losses in order to avoid double recovery. 
    Under the valuation scaling approach, trustees are entitled to scale 
    restoration actions based on the total diminution in value of lost or 
    diminished services from injured public trust natural resources not 
    recovered by a private party. One component of this total diminution in 
    value is the resulting reduction in economic rent, which represents the 
    income that accrues to a producer as a result of access to an unpriced 
    natural resource. The procedures identified for calculating economic 
    rent are well accepted economic procedures. The rule, in Sec. 990.27, 
    provides standards for a case-by-case determination of reliable 
    application of any procedures employed by trustees.
        In general, private parties can make claims for damages under 
    common law only when a private proprietary interest has been injured 
    (with an exception under admiralty that commercial fishermen do not 
    require an injury to a proprietary interest). These claims are 
    generally limited to ``economic'' (i.e., financial) losses. This 
    restriction excludes claims for lost consumer surplus attributable to 
    impaired recreation. See Alaska Sport Fishing Ass'n v. Exxon Corp., 34 
    F.3d 769 (9th Cir. 1994) (affirming dismissal of private claims on 
    behalf of approximately 130,000 recreational anglers seeking 
    compensation for the Exxon Valdez spill.)
        Ambiguities could arise where impaired recreational uses of public 
    natural resources are linked with uses of private property that is 
    injured due to an incident. In this case, the trustees would seek full 
    recovery occur except for those losses being sought by private parties 
    so that double recovery did not occur.
        The loss of government fees attributable to a reduction in 
    government services as a result of injuries from an incident are 
    appropriately elements of public claims. On the other hand, the changes 
    in expenditures captured by the multiplier effect do not represent 
    public losses. For example, when an incident occurs, tourists may shift 
    the location of their vacations to other substitute sites. The loss in 
    hotel and restaurant business at the site of the incident will have a 
    ripple effect on suppliers of goods and services for those businesses. 
    The ``multiplier effect'' captures the second- and later-round losses 
    in expenditures from an incident. However, the shift in tourist 
    expenditures to hotels and restaurants at substitute sites (and to 
    substitute activities) will bring comparable gains, with a comparable 
    positive multiplier effect. The net impact will be zero in markets in 
    which there is no change in price or direct impairment of productive 
    capacity as a result of the incident. Consequently, public claims do 
    not take into account shifts in expenditures as a result of the 
    incident. Private parties may be able to file claims for such losses.
        In addressing claims for subsistence losses the trustees must take 
    into account all of the services provided by the injured resources, 
    including nutrition and cultural/spiritual values.
        Because evaluation of compensatory restoration actions requires 
    scaling of the natural resources or services lost and linking them to 
    appropriate compensatory restoration actions, there will be no double 
    recovery for services restored under primary restoration actions. This 
    approach should also ease concerns over speculative injuries being 
    included in an assessment, as only measurable service losses, and only 
    public losses, will be included.
    Restorable Natural Resources
        Comment: Some commenters noted that the rule should not limit 
    restoration to ``restorable'' natural resources or services since, from 
    an ecosystem point of view, almost any injury can be redressed at least 
    in part even if the particular services or site cannot be.
        Response: NOAA agrees and believes the rule is sufficiently 
    flexible to provide compensation for those natural resources or 
    services that are not directly restorable.
    Types of Compensatory Actions
        Comment: One commenter stated that the rule should require that 
    lost services and the replacement services be truly equivalent in type 
    and quality. Other commenters, however, suggested that trustees may 
    also consider, when establishing the range of compensatory restoration 
    actions, actions that provide comparable injured natural resources and/
    or services. These commenters noted that the rule is unclear whether 
    trustees may examine restoration options that provide comparable 
    services in those cases where there are sufficient options that restore 
    same-type services. The commenters suggested that this limitation 
    should be removed and trustees permitted to identify and choose any 
    restoration options since a limitation to ``same or comparable'' 
    services is too narrow given the complexity of natural ecosystems and 
    their use (and nonuse) by humans. One commenter stated that the 
    division between ecological and human services is blurry and that in 
    planning restoration of lost services, it is often possible to restore 
    both ecological and human services through the same action. Other 
    commenters pointed out that the rule does not require that the selected 
    compensatory restoration actions will have any connection whatever with 
    the injured natural resources.
        Response: The rule states that trustees must consider compensatory 
    restoration actions that provide services of the same type and quality 
    and comparable value as those injured. However, if a reasonable range 
    of actions meeting these criteria is not available, trustees are 
    afforded the flexibility to consider actions that provide natural 
    resources and services of comparable type and quality. The rule also 
    develops a clear linkage between the injured natural resources and 
    services and the selected compensatory action(s) by requiring that 
    trustees develop restoration alternatives that provide services of the 
    same or comparable type and quality.
    Scaling
    Scaling Primary Restoration Actions
        Several commenters suggested that scaling of primary, as well as 
    compensatory, restoration will be necessary.
        Response: The rule has been revised to provide that scaling of 
    actions generally applies to primary restoration actions that involve 
    either replacement or acquisition of equivalent natural resources and/
    or services.
    Scaling Compensatory Restoration Actions
    Inclusion of Passive Use Values
        Comment: Some commenters stated that the heavy reliance on services 
    for 
    
    [[Page 486]]
    scaling may result in passive use services and services flowing from 
    the unique character of a natural resource being excluded from 
    recoveries, and that, even if they are included, the direct restoration 
    approach is unlikely to be successful. Some commenters stated that 
    passive uses should specifically be used in scaling the restoration 
    actions.
         Some commenters noted that the loss of passive values should be 
    compensated because such values represent part of the total value, 
    therefore damages, under OPA. Other commenters noted that the rule 
    should encourage rather than discourage the recovery of passive values 
    in order to increase the incentives for actions to avoid and reduce 
    such damages.
        Several other commenters specifically argued that passive use 
    values should not be included in scaling restoration actions, primarily 
    because such values cannot be measured reliably. Other commenters 
    stated that including such values would unreasonably extend the scope 
    of potential liability for responsible parties; would generate 
    overstated damage claims, and would be punitive. Some of these 
    commenters argued that such values are inappropriate for compensation 
    because they are already incorporated into the legal requirements and 
    compliance programs of OPA and, therefore, recovery of such values in 
    natural resource damage cases would result in double recovery. Some 
    commenters stated that Congress did not expressly provide for the 
    recovery of passive values in OPA and that such values are overly 
    inclusive and unrealistic. One commenter suggested that passive value 
    loss is not meaningful within the statute.
        Some commenters stated that, generally, incidents involve short-
    term, transitory injuries, therefore recovery for lost passive values 
    is especially inappropriate because such recoveries would be punitive.
        Some commenters noted that future effects from injuries are highly 
    speculative and, in the case of small injuries, insignificant; 
    therefore, any passive value determinations should be reduced to real, 
    near-term losses if they are to be included in a damage claim. Other 
    commenters pointed out that compensable values should have a maximum 
    recovery period for the future. One commenter suggested that some 
    passive values involve behavioral traces, contrary to the proposed rule 
    definition, and that the rule should encourage the measurement of 
    observable damages, even for those who do not directly use the natural 
    resource. Other commenters suggested that such values are not only 
    speculative, but are not economic in nature.
        Response: NOAA believes that the flexibility provided by the range 
    of available scaling approaches will prevent the public from being 
    deprived of full compensation. By allowing trustees to consider 
    restoration actions providing natural resources and services of 
    comparable type, quality and value, the rule provides a means for 
    compensating the public for injuries to unique natural resources, even 
    in cases where direct restoration of these injured natural resources is 
    either not feasible or fails to bring the injured natural resources 
    and/or services fully back to baseline.
        NOAA notes that there is a general consensus in the economic 
    community that passive use values exist. Under OPA, and in accordance 
    with the Ohio decision, passive use values may be used in calculating 
    the level of compensation necessary to fully compensate the public. The 
    procedures used to quantify passive use losses are subject to the same 
    standards for acceptable procedures in Sec. 990.27 as all other 
    procedures used to scale compensatory restoration actions. NOAA 
    recognizes that in cases involving temporary injury, individuals may 
    not experience a significant sense of loss. However, there are cases 
    where the death of individual members of a species may cause a 
    significant loss in passive use values even though the species levels 
    may at some point return to baseline.
        Where appropriate, NOAA supports the inclusion of reliably 
    calculated passive use values in the scaling process. NOAA notes that 
    some of the commenters' concern about inclusion of passive use losses 
    may have been addressed by defining compensation for interim losses in 
    terms of the cost of compensatory restoration actions rather than as 
    the value of interim losses. Furthermore, in the revised format for 
    claims, valuation procedures, including stated preference methods, are 
    used to make relative comparisons between the loss and the compensatory 
    restoration action gains, rather than to generate absolute dollar 
    amounts of lost value for a claim. Scaling compensatory restoration 
    actions may involve a single survey eliciting the direct resource-to-
    resource trade-offs between the injured natural resources and potential 
    compensatory natural resources. In this case it is not necessary to 
    elicit a monetary value for natural resources.
        Alternatively, scaling may involve a two-sided calculation, in 
    which measures of both loss due to injury and gains from compensatory 
    restoration actions are estimated separately. Where valuation 
    procedures are employed, the decision as to the appropriate scale of a 
    restoration action will require a relative comparison of the loss in 
    value and the potential gains in value. NOAA recommends that, where 
    feasible, trustees should use the same or similar valuation procedures 
    for both sides of the calculation in order to reduce the possibility of 
    bias in the scaling calculations.
    Inclusion of Nonmeasurable Functions
        Comment: Some commenters stated that the rule should include 
    nonmeasurable functions provided by natural resources, allowing for 
    subjective assessments by trustees in determining the value of such 
    losses. One of these commenters specifically requested that the rule 
    acknowledge the spiritual, cultural, and religious nature of services 
    unique to tribes. Some commenters argued that full consideration must 
    be given to all of the natural resource services, whether they are of 
    direct human use or not.
        Response: The rule does not limit the range of services to be 
    included in scaling compensatory restoration actions, except to the 
    extent that the procedures used to assess service injuries and scale 
    compensatory restoration meet the standards presented in Sec. 990.27.
    Need for Guidelines in Conduct of Scaling
        Comment: Many commenters suggested that the rule should contain 
    guidelines for the scaling approach and procedures in the rule. Several 
    commenters argued that economic valuation procedures are not 
    sufficiently accurate or reliable at this time to allow trustees to 
    make the comparison of services gained to services lost in a reliable 
    way in many cases. Some commenters noted that detailed guidance is 
    necessary to expedite damage claims and to avoid lengthy and expensive 
    litigation.
        Some commenters stated that experimental and/or unreliable scaling 
    procedures should not be accorded the rebuttable presumption under the 
    rule. Several commenters argued that the absence of standards would 
    allow the rebuttable presumption for any valuation procedure, no matter 
    how poorly structured, including unnamed procedures that the trustees 
    believe are appropriate. Therefore, some of these commenters stated 
    that the rule should clearly define what ``valid'' and ``reliable'' 
    mean with regard to assessment procedures. The 
    
    [[Page 487]]
    commenters also suggested that trustees who choose to use new or 
    unorthodox procedures should be required to demonstrate that these 
    procedures provide comparable or higher levels of validity and 
    reliability than the procedures previously recognized by NOAA.
        Several other commenters, however, supported the decision to remove 
    specific guidance on procedures from the rule and place them in 
    guidance documents. These commenters argued that the rule should not 
    establish premature or overly prescriptive procedural requirements for 
    any economic or natural science procedure, since such procedures are 
    the subject of research and refinement.
        Response: NOAA notes that the rule has been revised to provide a 
    set of standards in Sec. 990.27 with which to judge all procedures 
    under consideration, as well as factors to consider when selecting 
    among those procedures. Assessments using procedures that meet these 
    standards may receive the rebuttable presumption, if they are otherwise 
    performed in accordance with the rule. In addition, NOAA is considering 
    the development of a separate guidance document on resource-to-
    resource, service-to-service, and valuation scaling procedures.
    Choice of Resource-to-Resource and Service-to-Service vs. Valuation 
    Scaling Approaches
        Comment: Many commenters opposed mandating the use of the service-
    to-service scaling approach for restoration options providing the 
    ``same type and quality'' of services subject to ``comparable scarcity 
    and demand conditions.'' These commenters state that this requirement 
    restricts the flexibility of trustees in an assessment. The commenters 
    stated that the restriction is unworkable, given the lack of direction 
    as to what constitutes ``same type and quality'' and ``comparable 
    scarcity and demand conditions.'' The commenters stated that trustees 
    should be allowed maximum flexibility in selection of the most 
    efficient assessment procedure. Some commenters pointed out that the 
    requirement of service-to-service for any portion of restoration where 
    in-kind natural resources or services are feasible will in some cases 
    present difficulty in application of valuation procedures for remaining 
    portions of a claim due to problems of double counting or indivisible 
    losses and gains. The commenters argued that the selection of 
    procedures should be based on factors such as reasonable cost, 
    validity, reliability and incident specific considerations, which will 
    not always favor the use of service-to-service scaling over valuation. 
    The commenters pointed out that OPA defines the measure of damages to 
    include ``diminution in value'' to the public; therefore, NOAA's 
    authority to preclude trustees from assessing diminution in value in 
    monetary terms is questionable. Some of these commenters argued that 
    the service-to-service approach is not yet well developed, especially 
    in the areas of human uses. However, the commenters pointed out that 
    economic procedures have been well developed and frequently relied upon 
    and should be accorded equal weight in the rule.
        Some commenters noted that the rule does not clearly specify when 
    trustees should use the service-to-service instead of the valuation 
    scaling approach.
        Response: NOAA agrees with the comments recommending elimination of 
    the requirement to use a resource-to-resource or service-to-service 
    scaling procedure when determining the scale of a compensatory 
    restoration action that provides natural resources and/or services that 
    are of the same type and quality and are subject to comparable natural 
    resource scarcity and demand conditions as those lost. Consequently, 
    NOAA has modified the rule to maximize the trustees' flexibility in 
    choosing the most appropriate scaling approach. The trustees must now 
    consider, but are not required to implement, a resource-to-resource or 
    service-to-service approach for actions that provide natural resources 
    and/or services of the same type and quality, and of comparable value 
    to those lost. NOAA also has replaced the phrase ``comparable scarcity 
    and demand'' with ``comparable value.'' The rule requires that the 
    relative value of injured and replacement natural resources and 
    services be evaluated.
    Use of Public Natural Resources for Restoration Actions
        Comment: Some commenters argued that the compensatory restoration 
    approach would transfer to the polluter for free the consumer surplus 
    provided by public natural resources. The commenters stated that many 
    public goods and natural resources provide a public benefit in excess 
    of the cost of maintaining them. The commenters pointed out that a 
    restoration-based approach is preferable to industry because it focuses 
    on the cost of restoring an injury, rather than the value of the 
    injury; that the difference between these two figures is the surplus 
    value inherent in the natural resource. Therefore, the commenters 
    argued that the responsible party pays the ``cost,'' the ``surplus'' is 
    contributed and the appropriate ``value'' is achieved. The commenters 
    stated that the rule must be amended to require restoration actions of 
    a magnitude that create a net benefit (i.e., subtracting the pre-
    existing value) equal to the injury.
        Response:  The rule does require that restoration actions create 
    comparable benefits to those that were lost due to the injury. NOAA 
    agrees that trustees should only count the incremental benefits created 
    by a restoration action. For example, if an action is rehabilitating a 
    wetland currently functioning at 50% effectiveness, only the 
    incremental improvements beyond 50% should be taken into account. 
    Trustees also should carefully consider the opportunity costs 
    associated with the use of public natural resources for compensatory 
    restoration actions. For example, if the restoration action is to 
    transform land currently in upland use into marsh, the opportunity cost 
    of forgoing the previous upland uses needs to be taken into account.
    Consideration of Economic Benefits
        Comment: One commenter suggested that scaling should also consider 
    the economic benefits resulting from the incident.
        Response: The economic benefits resulting from incidents will 
    accrue primarily to individuals and, in most cases, will represent 
    transfer payments rather than net social benefits. For example, whereas 
    hotels in the area of an incident may lose tourist business, hotels in 
    a substitute location may incur gains comparable to the on-site hotel 
    losses. Just as losses to private parties are not included in the 
    trustees' claim, neither should private gains be included.
    Use of Same Procedure to Measure Injured and Replacement Natural 
    Resources/Services
        Comment: Several commenters argued that the same procedure should 
    be used to measure the value of losses and value of benefits of 
    restoration. One commenter pointed out that the use of different 
    assessment procedures for the same injury or loss would make it 
    impossible to adjust accurately for bias and that the rule should 
    require that trustees use procedures that are not subject to upward 
    bias.
        Response: NOAA agrees that, where feasible, use of the same 
    procedure to measure the value of injuries and benefits is recommended 
    to reduce the opportunity for introducing bias in the scaling of 
    compensatory restoration. However, NOAA believes that requiring 
    trustees to use the same procedures to 
    
    [[Page 488]]
    measure the value of injuries and benefits is overly restrictive, since 
    such a requirement may preclude trustees' ability to apply revealed 
    preference procedures (i.e., procedures based on data on use of natural 
    resources) in a range of circumstances. Revealed preference methods can 
    only be used to value natural resources and opportunities to use 
    natural resources with characteristics that fall within the range of 
    currently existing natural resources and use opportunities. 
    Consequently, though it may be feasible to value lost recreational use 
    of a particular natural resource with a revealed preference method, 
    such as the travel cost model, it will not be feasible to evaluate the 
    benefits of a proposed compensatory restoration action if its 
    attributes are outside of the range of what is currently available. For 
    example, if there are no dune walkways at regional beaches it will not 
    be feasible to value a restoration action constructing a dune walkway 
    with revealed preference methods. NOAA believes that the issue of bias 
    is addressed by the requirement in Sec. 990.27(a) requiring assessment 
    procedures to be reliable and valid for the particular context.
    Discretion to Use Valuation Procedures
        Comment: Several commenters argued that the rule gives virtually 
    unbounded discretion to the trustees with regard to valuation 
    procedures. The commenters were concerned that valuation ``sneaks in 
    the back door'' through the restoration planning process by allowing 
    the option to value lost services while not valuing the services 
    gained.
        Response: NOAA believes that the conditions under which the 
    trustees may employ the valuation scaling approach are sufficiently 
    specified in Sec. 990.53(d). Under the valuation scaling approach, 
    trustees explicitly or implicitly measure the value of both the natural 
    resources/services lost and natural resources/services provided by the 
    selected restoration action(s). The one exception is when the valuation 
    of the replacement natural resources/services cannot be performed 
    within a reasonable time frame or at reasonable cost, but the valuation 
    of natural resources/services lost is practicable.
        Comment: Some commenters requested clarification as to what 
    conditions invoke the ``unreasonable cost'' exception in which trustees 
    may use the interim loss in value to scale the restoration claim, 
    rather than scaling the action by demonstrating that an action of the 
    chosen size will provide benefits equal to the interim losses from the 
    injury.
        Response: Assessment costs are deemed to be unreasonable if 
    trustees fail to follow the guidance provided in the rule. For example, 
    the additional costs of a procedure must be related to the information 
    expected to be gained with that procedure, as provided in Sec. 990.27 
    of the rule. These standards are intended to avoid excessive costs in 
    an assessment.
        Comment: Several commenters pointed out that the rule does not, but 
    should, explicitly provide for the use of valuation procedures when a 
    responsible party challenges the cost of service-to-service restoration 
    as disproportionate to the value of the damages.
        Response: Section 990.14(c)(5) allows responsible parties to 
    request assessment procedures other than those selected by the 
    trustees, if they follow the procedures for making the request in 
    Sec. 990.14(c)(5) and the alternative procedures meet the standards for 
    acceptable procedures provided in Sec. 990.27.
        Comment: Several commenters argued that the responsible party 
    should not have the unilateral right to require economic valuation of 
    restoration options. The commenters noted that such an option would 
    result in the responsible party having more rights than the trustees to 
    choose assessment procedures, which would be improper and unfair. The 
    commenters stated that the trustees, in all cases, should have the 
    right to use valuation procedures.
        Another commenter argued that the option for the responsible party 
    to request a more specific procedure contravenes OPA, which requires 
    trustees to perform assessments, advance costs, file, and establish 
    claims for damages.
        Response: The rule has been revised to allow the trustees to reject 
    the responsible parties' proposed alternate assessment procedures if 
    they do not meet the criteria specified under Sec. 990.14 (c)(5)(iii), 
    and thus the requirements for acceptable procedures described in 
    Sec. 990.27.
    Discounting and Uncertainty
    Addressing Uncertainty
        Comment: Several commenters stated that trustees should be required 
    to address uncertainties in measures of losses and gains as a separate 
    matter from discounting. Some of these commenters suggested addressing 
    uncertainties using a Monte Carlo framework. The commenters pointed out 
    that differences in discount rates are driven by financial risks, which 
    are unrelated to uncertainties in measuring lost or replacement service 
    flows. The commenters stated that the use of risk-adjusted discount 
    rates should be eliminated from the rule.
        Other commenters, however, suggested that the language ``must 
    address the uncertainties associated with the predicted consequences of 
    the alternative'' should be revised to read ``should address when 
    possible in a valid manner.''
        Response: NOAA agrees that, where feasible, the trustees should use 
    risk-adjusted measures of losses and gains, in conjunction with a 
    riskless rate of discount reflecting the social rate of time preference 
    for natural resources. However, in cases where the streams of losses 
    and gains cannot be adequately adjusted for risks, trustees should use 
    a discount rate that incorporates a suitable risk adjustment to the 
    riskless rate. NOAA agrees that in some cases, Monte Carlo analysis may 
    be an appropriate approach to addressing uncertainties. The discount 
    rate employed in a scaling application is to reflect the social rate of 
    time preference for the injured and replacement natural resources and/
    or services. Because of the difficulty in determining the rate of time 
    preference for goods, such as natural resources, that are not generally 
    sold in a market, a real rate of 3% is recommended as a riskless rate, 
    unless justification is presented for a rate more appropriate for the 
    specific context.
    Use of ``Over-Compensation''
        Comment: One commenter questioned the amount of ``over-
    compensation'' that should be included in the restoration plan as a 
    contingency for possible lack of restoration action success. The 
    commenter suggested that such over-compensation could be used to 
    account for restoration aspects that do not produce the expected 
    results or fail completely. The commenter suggested that responsible 
    parties would agree to over-compensation if doing so would provide 
    absolute closure for the responsible party.
        Response: This comment basically restates the requirement in 
    Sec. 990.53(c)(4) that trustees must evaluate the uncertainties 
    associated with the projected consequences of the restoration action. 
    The selected restoration action(s) should be scaled to incorporate the 
    reasonable range of uncertainty associated with the level of natural 
    resources/services that will be provided by the action(s). 
    
    [[Page 489]]
    
    Bounds on discount rates
        Comment: Several commenters suggested that the rule should place 
    some bounds on an appropriate discount rate for societal time 
    preference. These and other commenters also requested guidance on risk 
    and uncertainty.
        One commenter suggested that, in the case where services will be 
    lost or interrupted for a relatively short period of time, trustees 
    should use the OMB projected rates of return on 20-year U.S. Treasury 
    bills, rather than a long-term average of past rates. The commenter 
    noted that a long-term average may be unduly influenced by unusually 
    high or low past rates arising from past economic circumstances not 
    applicable to the period in question. The commenter suggested that, 
    should the final rule mandate a long-term average, trustees should 
    calculate that average as a moving average to give more weight to 
    recent rates. The commenter also recommended that, in the event that 
    the damages must be estimated for an extended period, the most distant 
    projection available from OMB be used. Finally, the commenter suggested 
    that the discount rates for HEA should be real, after-tax, riskless 
    rates.
        Some commenters suggested that a discussion should be placed in the 
    preamble that describes a discount range of 3% to 7% as generally 
    reasonable for most future benefits associated with restoration 
    actions, and a range of 0% to 3% for discount rates associated with 
    natural resource and/or service losses. The commenters stated that it 
    is appropriate to discount future losses at a very low rate, if at all.
        Some commenters suggested that the procedure for determining a 
    discount rate should reflect the guidelines for water resource projects 
    since those projects provide a much closer analogy to natural resource 
    damage assessments than the lease-purchase or benefit/cost and cost-
    effectiveness analysis currently in use.
        Response: For scaling restoration actions, the appropriate rate of 
    discount is the social rate of time preference for the injured natural 
    resources, i.e., the rate at which society is willing to trade off 
    natural resources during the period of the incident for natural 
    resources during the period of restoration action. NOAA is recommending 
    that use a 3% discount rate as a proxy for the social rate of time 
    preference (unless justification for a more appropriate rate is 
    presented).
        Because the public use of natural resources does not occur 
    primarily through private market transactions, consumers do not 
    necessarily adjust their inter-temporal consumption of natural 
    resources in response to the relevant intertemporal financial trade-
    offs available to them, as represented by the U.S. Treasury rates. U.S. 
    Treasury rates (both realized and projected future rates) have been 
    relatively volatile over the last few years, even for long-term rates. 
    There is no particular reason to assume that the volatility of the 
    observed financial rates carries over to the social rate of time 
    preference for these non-marketed goods.
        NOAA is considering the development of a separate guidance document 
    on resource-to-resource, service-to-service, and valuation scaling 
    procedures that would address issues pertaining to discounting, risk, 
    and uncertainty in greater detail.
        Comment: One commenter also stated support for the use of state and 
    tribal borrowing rates in calculation of present value of assessment 
    costs. This commenter agreed with the use of discount rates that 
    represent the yield on recoveries available to the trustees. Several 
    commenters noted that, when the state is the lead administrative 
    trustee, the corresponding state borrowing rate should be used as the 
    discount rate instead of the U.S. Treasury rate.
        Response: NOAA supports the use of state or tribal rates where 
    appropriate. However, designation of the lead administrative trustee is 
    primarily an administrative decision and should not substantively 
    affect the choice of an appropriate discount rate, except to the extent 
    that it affects the yield on recoveries available to trustees.
    Discounting and HEA
        Some commenters suggested that the rule should clarify the role of 
    discount rates in HEA. The commenters stated that the rule should 
    explicitly state the assumptions that the unit dollar value of forgone 
    services equals the unit dollar value of the restoration services and 
    these dollar values do not change over time, in order for financial 
    discount rates to be appropriate in HEA models.
        Response: NOAA does not disagree with the substance of these 
    comments, but believes that such a level of detail regarding specific 
    procedures is most appropriately included in guidance documents, rather 
    than the rule itself.
    Sensitivity of Scale to Discount Rate Choice
        Comment: Some commenters noted that the choice of discount rate is 
    largely responsible for the resulting size of the compensatory 
    restoration action.
        Response: The sensitivity of the scale of compensatory restoration 
    action to a given discount rate will depend on the relationships among 
    a number of factors including, but not limited to, the duration of the 
    injury, the time necessary for the compensatory restoration action(s) 
    to provide full service flows, and the lifespan of the compensatory 
    restoration action(s).
    Choice of Appropriate Inflation Index
        Comment: One commenter recommended using the Gross Domestic Product 
    (GDP) deflator when the adjustment is being made to determine the 
    present value of future restoration costs or when a stream of future 
    service flows is being discounted, and using the Consumer Price Index 
    when lost consumer surplus requires discounting. The commenter stated 
    that when a clear distinction cannot be drawn, the GDP deflator should 
    be used because it is more general.
        Response: NOAA believes that this structure for scaling restoration 
    actions is generally acceptable and consistent with the rule language. 
    However, by definition, a quantity of services is already in real 
    terms. Quantities of services generally will not need adjustment with a 
    price index because they only appear in the scaling calculation, which 
    will generally be carried out in real terms (with a real discount 
    rate). For purposes of calculating restoration costs, more specific 
    indices, such as construction and employment cost indices, may be used 
    where appropriate and available.
    
    Section 990.54  Restoration Selection--Evaluation of Alternatives
    
    Selection Criteria for Alternatives
        Comment: Many commenters had suggestions for revisions to the 
    selection criteria for restoration alternatives. These commenters 
    argued that the selection criteria in the rule provide no overall 
    standard for selection of alternatives. Some commenters suggested that 
    without standards for evaluating and selecting restoration 
    alternatives, there are no meaningful bounds on responsible party 
    liability.
        Other commenters, however, argued that the rule should establish no 
    specific ``weight'' for any of the selection factors, that such a 
    requirement would limit the flexibility required for restoration and 
    could undermine the validity of the whole process. One commenter stated 
    that the requirement to minimize damages is unnecessary so long as 
    trustees are required to document the relevant factors and tradeoffs in 
    selecting a restoration alternative and 
    
    [[Page 490]]
    explain their selection in response to any public comments prior to the 
    implementation of the restoration plan.
        Response: NOAA believes that the modified criteria for evaluation 
    of restoration alternatives presented in Sec. 990.54 in the final rule 
    are sufficient to ensure that selected alternatives are reasonable, 
    cost-effective, and adequate to compensate the environment and public 
    for injuries to natural resources and/or services. The selection of 
    restoration actions that truly make the environment and public whole is 
    a highly incident-specific analysis, and NOAA believes that prescribing 
    a rigid hierarchy of selection criteria will not facilitate achieving 
    OPA's compensatory goal. Trustees must evaluate the numerous selection 
    criteria listed in the rule, at a minimum, and describe in the draft 
    restoration plan how each factor played in the selection and 
    elimination of alternatives.
        Comment: Some commenters pointed out that, if all the parties agree 
    to a restoration solution, the trustees should not have to develop 
    numerous restoration alternatives.
        Response: Under the rule, trustees may settle claims for natural 
    resource damages at any time, provided that the settlement is adequate 
    in the judgment of the trustees to satisfy the goal of OPA and is in 
    the public interest. However, it is expected that even early settlement 
    will entail an evaluation of available restoration actions in order to 
    meet the varied interests of all parties.
    Cost Effectiveness
        Comment: Some commenters argued that the rule should specifically 
    require cost effectiveness as the major selection criterion. Other 
    commenters disagreed, stating that a simple requirement to select the 
    most ``cost-effective'' option is too narrow and should not be 
    required. These commenters argued that cost-effectiveness alone 
    disregards distributional differences and ecological integrity, which 
    may well leave a natural resource seriously impaired. The commenters 
    suggested that the selection decision should be driven by criteria that 
    emphasize making the environment and public whole, both in aggregate 
    and by user group.
        Response: NOAA fully supports choosing the least costly restoration 
    action(s) among equivalent alternatives. However, NOAA believes that 
    prescribing a rigid hierarchy of selection criteria, including 
    designating one criterion as always singularly more important than 
    others, will not facilitate achieving OPA's compensatory goal.
    Minimization of Costs/Damages
        Comment: A number of commenters stated that, when sufficient data 
    on costs and benefits are available, trustees should ultimately base 
    their selection of restoration alternatives on a cost-effective 
    approach that will minimize total damages or make the public whole at 
    the least cost. The commenters stated that selection of the alternative 
    that minimizes damages is consistent with economic theory, OPA's 
    legislative history, and the decision in Ohio. Many other commenters 
    opposed any strict requirement to minimize damages as inconsistent with 
    the statutory language of OPA (section 1106(d)(1)) as well as the 
    holding in Ohio overturning the approach contained in the 1986 version 
    of the CERCLA rule that directed trustees to recover the lesser of 
    restoration cost or diminution in value. The commenters stated that OPA 
    contains the statutory preference of restoration, and not the 
    minimization of damages.
        Response: NOAA supports the consideration of the relationship 
    between costs and benefits when selecting a preferred restoration 
    alternative(s). However, NOAA does not support reducing the selection 
    process to a strict cost-benefit or cost-minimization decision rule. 
    The rule requires trustees to identify and consider a reasonable range 
    of restoration alternatives for a given incident, or for individual 
    injuries of an incident. The rule further enumerates specific criteria 
    that must be considered by trustees in selecting preferred restoration 
    approaches from the range of alternatives. These criteria include 
    feasibility, likelihood of success, effectiveness, and speed with which 
    baseline will be returned, benefits to multiple natural resources, and 
    cost. Consideration of these criteria will constitute a qualitative 
    cost-benefit analysis that is appropriate to the task at hand--
    restoration--and will ensure that cost-effective actions are selected.
    Qualitative Assessments
        Comment: Some commenters stated that benefits should be required to 
    be quantified in cases where it is practicable. One commenter suggested 
    that, for cases where benefits cannot be measured at reasonable cost, 
    the assessment should be qualitative; however, qualitative assessment 
    should not be used to justify very costly restoration.
        Response: The resource-to-resource, service-to-service, and 
    valuation scaling approaches all inherently involve the quantification 
    of benefits of the selected restoration alternative(s), either in terms 
    of quantifying the level of natural resources/services or the value 
    provided by the restoration actions. The evaluation standards for 
    selecting the preferred alternative(s) presented in Sec. 990.54 
    represent a combination of quantitative and qualitative factors.
    Not Grossly Disproportionate
        Comment: A number of commenters stated that the trustees should 
    also be required to compare costs to benefits/value of services, to 
    determine whether the cost of the alternative being evaluated is 
    grossly disproportionate to the value of the injured natural resources 
    or, alternatively, to the benefits of that alternative. Some commenters 
    requested that NOAA clarify the term ``grossly disproportionate'' and 
    state whether it has a role in the process, especially in the 
    compensatory restoration process.
        Response: NOAA believes that the evaluation and selection of 
    restoration alternatives according to the factors provided in the rule 
    will ensure that preferred actions are commensurate with the value of 
    natural resource losses.
    Reinstatement Costs
        Comment: One commenter argued that restoration should be based on 
    the reasonable cost of reinstatement of the environment under the 
    international regime.
        Response: The international regime allowing recovery of reasonable 
    reinstatement costs generally incorporates only direct restoration of 
    natural resources directly injured by an incident, which is more narrow 
    than actions authorized by OPA and thus would not be appropriate for 
    this rule.
    Violation of Laws and Regulations
        Comment: Another commenter argued that the criterion concerning 
    violation of laws or regulations be taken into account in determining 
    the viability of a particular alternative, rather than in determining 
    which restoration alternative(s) is preferred.
        Response: NOAA agrees that legality of alternatives is a screening 
    criterion to eliminate alternatives from consideration, and has amended 
    Sec. 990.53 of the rule to reflect this.
    Effects on Public Health and Safety
        Comment: Some commenters noted that any alternative considered 
    should not exacerbate natural resource injuries or otherwise cause 
    adverse effects on public health, safety or the environment. 
    
    [[Page 491]]
    
        Response: NOAA agrees. Section 990.54 of the rule directly states 
    that these factors must be considered by trustees when evaluating 
    restoration alternatives.
    Pilot Projects
        Comment: Several commenters suggested that the provision allowing 
    pilot projects should be revised, or at least clarified. Some of the 
    commenters argued that the responsible parties should not be required 
    to fund pilot projects. Other commenters stated that pilot projects 
    should only be allowed where they can be shown to be reasonable, 
    relevant, and linked directly to the incident of concern.
        Response: The rule has been clarified to indicate that pilot 
    projects may only be undertaken when additional information is needed 
    to identify and evaluate the feasibility or likelihood of success of 
    restoration alternatives, and where they can be undertaken in a 
    reasonable time frame and at a reasonable cost.
    
    Section 990.55--Restoration Selection--Preparation of a Draft and Final 
    Restoration Plan
    
        Comment: One commenter expressed concern about placing injury 
    determination and quantification information in the Draft Restoration 
    Plan, making this information available to the public and the 
    responsible party, all within the context of civil litigation. The 
    commenter recommends that trustees be granted some litigation privilege 
    to protect their potential claim.
        Response: This information, if relied upon by the trustees in 
    decisionmaking, is essential to meaningful public involvement.
        Comment: Some commenters suggested that the proposed restoration 
    planning process prior to presenting a demand to responsible parties 
    places unreasonable expectations on the parties. These commenters 
    suggested that the rule naively assumes that restoration efforts can be 
    described in terms of a detailed restoration plan in a short period of 
    time after completing assessment studies. These commenters, noting the 
    Exxon Valdez experience, suggested that this will not always be 
    practicable. The commenters requested that the rule provide trustees 
    authority to make additions, substitutions, or other modifications to 
    the restoration plan based on experience and additional information 
    gained in the implementation phase.
        Response: The extent to which trustees can, and need to, develop 
    specific, detailed workplans to implement restoration actions as part 
    of draft or final restoration plans will depend on the circumstances of 
    the incident, the nature of the preferred restoration actions, and 
    trustees' relationship with responsible parties. It may be possible to 
    reach binding agreements regarding the nature and scale of actions that 
    will constitute restoration and compensation, with an agreed upon 
    timetable for developing the implementation plans for those actions. 
    Often it will be advantageous to all parties that the responsible 
    parties or their representatives develop the workplans based on the 
    trustees' goals and objectives. However, if a cooperative relationship 
    has not been possible or effective, and trustees expect they may have 
    to implement restoration themselves or litigate to recover the funds to 
    implement restoration, it is in the best interests of the public for 
    trustees to have a plan that provides the most accurate estimate of 
    required restoration costs possible. Depending on the preferred 
    alternative, detailed work or implementation plans may have been 
    developed for prior actions, parts or all of which may be applicable to 
    the incident at hand.
        Comment: Some commenters disagreed with a prescribed minimum public 
    comment period for all incidents, while others stated that 30 days 
    should be an absolute requirement, with a corresponding requirement 
    that trustees respond to public comments in the subsequent 30 days.
        Response: NOAA has removed a specific time requirement for a public 
    notice and comment period, realizing that the circumstances of 
    individual incidents and localities, and in addition the requirements 
    for NEPA or other regulatory compliance, are so varied that any one 
    specified time may be inappropriate.
        Comment: A number of commenters stated their belief that 
    restoration monitoring costs are not recoverable as natural resource 
    damages. These commenters cite judicial decisions barring oversight 
    costs as recoverable response costs under CERCLA, and an explicit 
    reference to ``monitoring'' within OPA, respecting recovery from the 
    Oil Spill Liability Trust Fund of the costs of monitoring removal 
    actions. Other commenters agreed that monitoring is essential to the 
    successful implementation of restoration, and urged that rule language 
    be more explicit regarding the scope, extent, and purpose of 
    recoverable monitoring costs. These commenters suggested that 
    monitoring costs should be related to the value of the natural resource 
    being restored, that monitoring should only be conducted long enough to 
    ensure that the action is proceeding as planned, and that the rule 
    should provide for performance bonds if implementation is conducted by 
    responsible parties.
        Response: NOAA believes that restoration monitoring costs are a 
    recoverable component of natural resource damages. Monitoring is 
    essential to ensure that restoration actions accomplish their intended 
    goals and objectives and do not cause unanticipated harm to the 
    environment or public health. In addition, monitoring is essential to 
    determine whether the terms of restoration agreements have been met, 
    upon which a release from liability is premised. NOAA agrees that the 
    rule itself should speak to the purposes and scope of monitoring, and 
    has amended the rule accordingly.
    
    Section 990.56--Use of Regional Restoration Plans or Existing 
    Restoration Projects
    
        Comment: Several commenters argued that using Regional Restoration 
    Plans to spend money generated from simplified assessments is contrary 
    to OPA and traditional tort principles of individualized injury and 
    causation. Some commenters noted that the legislative history of OPA 
    demonstrates a rejection of such regional approaches to restoration 
    (H.R. 1465, 1st Cong., 1st Sess. (1989), a predecessor bill to OPA, 
    contained a natural resource damage civil penalty section (1006(g)(4)) 
    that allowed funds recovered to go to ``general enhancement of the 
    ecosystem''). The commenters made the point that common law tort 
    principles applicable under OPA require damages to be used to restore a 
    specific injury to a specific natural resource in order to be 
    compensatory rather than punitive.
        Some commenters argued that, for small incidents where incident-
    specific plans would be unreasonable, trustees should allow natural 
    recovery. The commenters stated that there is no OPA mandate to restore 
    injured natural resources and services regardless of the scope and 
    scale of those injuries, and that, in such cases, OPA firmly implies 
    liability for small incidents is de minimis in the absence of actual 
    evidence of significant natural resource services losses. One commenter 
    suggested that regional plans could not possibly identify precisely 
    where discharged oil would go, and in the actual event of an incident, 
    a regional plan will likely be inapplicable. Other commenters noted 
    that before a regional plan could be used, a link between the actual 
    injury and the plan must be established.
        Some commenters argued that such plans would be self-fulfilling and 
    
    
    [[Page 492]]
    become a proxy for investigating injuries. Several commenters noted 
    that, under these provisions, trustees could amass large sums of money 
    to undertake various quasi-public works projects, having no connection 
    whatsoever to any of the incident sites. These commenters argued that 
    this provision will allow trustees to essentially do an ``end run'' 
    around the legislative process and to pursue their own ends, which is 
    clearly not authorized by OPA.
        One commenter argued that this provision would be fundamentally 
    unfair to responsible parties who will have no opportunity to 
    participate in the development of these regional plans.
        Several commenters strongly encouraged the use of Regional 
    Restoration Plans, stating that trustees must have multiple options 
    available for redressing injuries. These commenters stated that 
    Regional Restoration Plans allow trustees to maximize the effectiveness 
    of a restoration action by combining recoveries from other incidents. 
    Some of these commenters noted that only Regional Restoration Plans can 
    provide for an effective response to the cumulative impacts of many 
    small incidents. These commenters argued that such plans are clearly 
    within the ambit of OPA and that there is no provision in OPA requiring 
    that damages collected be spent remediating the specific site injured. 
    In fact, the commenters noted that contrary intent is evident in 
    Congress' inclusion of acquisition of equivalent natural resources as a 
    restoration option.
        Several commenters expressed concern that the rule limits use of a 
    Regional Restoration Plan to situations where a simplified assessment 
    procedure was used. The commenters argued that whether damages from a 
    specific incident are best used independently, or to fund part of a 
    Regional Restoration Plan, is a separate issue that is not related to 
    the type of assessment procedure used. They stated that, if 
    implementation of a project plan provides suitable compensation for 
    injuries that occurred as a result of a discharge, trustees should be 
    able to use that specific project plan.
        Other commenters expressed concern about restrictive language 
    related to ``commingling'' of simplified assessment recoveries and the 
    use of newly developed Regional Restoration Plans. These commenters 
    stated that it would be difficult at best to define ``similar'' natural 
    resources or services in relation to small incident impacts and that 
    pooling of small incident damages should not be tied to such a 
    criterion. The commenters suggested that the only criterion for pooling 
    of small incident settlements should be the lack of affordable and 
    efficient restoration alternatives given the size of the damage 
    recovery.
        One commenter requested more guidance in the rule for criteria for 
    developing and implementing such plans. One commenter said the proposed 
    rule was unclear about the calculation of appropriate costs for cases 
    where the formulas or type A models were used and even more confusing 
    where calculation of such costs are necessary for the implementation of 
    a regional restoration plan. Another commenter stated that the costs of 
    developing regional plans is not an appropriate use of recovered 
    natural resource damages.
        Commenters proposed a number of guidelines to permit regional 
    restoration planning under OPA, when the trustee and the responsible 
    party agree that it is appropriate, including: (1) There is an 
    ecological relationship between the injured natural resources and the 
    objectives of the regional restoration plan; (2) on-site restoration is 
    either not technically feasible or not cost effective; (3) the level of 
    services provided by the proposed restoration action is substantially 
    similar to that provided by the injured natural resources; (4) the 
    restoration measures will be beneficial given the potential for natural 
    recovery; (5) the measures are likely to be successful in significantly 
    accelerating the natural recovery of the injured population or area; 
    (6) the proposal will not itself result in degradation of the 
    environment; and (7) the cost of the program is not out of proportion 
    to the value of the natural resources.
        One commenter asked whether NOAA will initiate a regional 
    restoration planning process and identify areas where regional plans 
    could be of high priority, or whether it is incumbent upon industry and 
    state trustees to do so. Another commenter noted that pre-incident 
    planning may not be achievable in all cases, and recommended NOAA's 
    rule endorse post-incident development of Regional Restoration Plans, 
    with public review and comment, for application of subsequent 
    recoveries.
        Some commenters suggested that regional restoration plans identify 
    areas within the region in need of restoration or acquisition that are 
    important to various species of fish and wildlife vulnerable to 
    incidents and prioritize them by cost of restoration. In addition, this 
    commenter suggested that the trustees be required to make a showing 
    that it is environmentally ineffective to restore the injured natural 
    resource and that restoration of another would provide substantially 
    greater benefit to the ecology injured by the incident.
        Some commenters suggested the importance of early public 
    involvement in the prioritization of areas most heavily injured by 
    incidents and to ensure that the restored areas serve the same human 
    populations as those served by the injured natural resources. One 
    commenter noted that Regional Restoration Plans inappropriately exclude 
    local participation in restoration planning, as large-scale efforts 
    would bar smaller attempts.
        Response: NOAA agrees that OPA intends that responsible parties be 
    held liable only for restoration needed to redress the injuries caused 
    by specific incidents. Injury must be determined under the rule for all 
    incidents. However, NOAA also views regional restoration planning as 
    one means to resolve liability for injuries in an expeditious and cost-
    effective manner.
        The rule has been amended to make it clear that in no event will 
    the use of a regional restoration plan violate OPA's limitation that 
    natural resource damages be used solely to restore, replace, 
    rehabilitate, or acquire the equivalent of the natural resources and/or 
    services injured by an incident. OPA's legislative history defines 
    ``equivalent'' natural resources as those that will enhance the 
    recovery, productivity, and survival of the ecosystem affected by a 
    discharge, preferably in proximity to the affected area (Conference 
    Report at 109). The requirements in the rule are strict enough to 
    ensure that regional restoration plans or other existing restoration 
    projects used in lieu of an incident-specific plan do not violate OPA's 
    constraints on expenditure of damages. Whether an existing plan or 
    project represents restoration, rehabilitation, replacement, or 
    acquisition of the equivalent will depend on the nature of the incident 
    and the restoration plan or project.
        The final rule also requires that use of possible restoration 
    actions in an existing plan or project be evaluated within the range of 
    restoration alternatives that trustees are required to consider, 
    including natural recovery. But the rule recognizes that it may be in 
    the best interests of all parties not to expend funds developing 
    incident-specific restoration plans in all instances.
        Experience with past incidents has shown that responsible parties 
    have often identified existing planned or proposed environmental 
    restoration actions that may have been developed by local governmental 
    natural resource agencies or environmental groups, and 
    
    [[Page 493]]
    proposed to fund these actions as compensation for the injuries of an 
    incident. NOAA intends regional restoration planning to build on this 
    cost-effective approach to restoration planning, by developing 
    databases that identify existing or desirable unfunded actions in a 
    manner that will allow an appropriate linkage between actions and 
    particular incidents. The geographic scale of a ``regional'' plan 
    database will likely vary with locality, variability of local 
    environmental conditions, and expected local impacts from incidents, 
    but actions can be scrutinized in terms of the type and scale of 
    natural resources and/or services they are expected to provide. If 
    projects match the incident in terms of the scale of injuries and the 
    scale of expected natural resources or services that will be provided, 
    responsible parties may be given the option to fund or implement the 
    project. If the scale of the incident and the project do not appear 
    consistent, trustees may request that responsible parties pay damages 
    equal to the relative proportion of the total cost of the project that 
    would compensate for the scale of injuries from the incident. Such 
    partial recoveries may be pooled until funding is adequate to implement 
    the project.
        The rule has been revised to eliminate restrictions on the type of 
    assessment procedures that will enable use of a regional restoration 
    plan or other existing restoration project, and have omitted any 
    restrictions on how partial recoveries may be pooled or commingled 
    pending collection of adequate funds to implement a project.
        Finally, the rule is clear in providing for responsible party 
    participation in identification of appropriate existing plans or 
    projects that will resolve their liability for the injuries from a 
    particular incident. The rule also provides that potentially 
    responsible parties be given an opportunity to participate in any pre-
    incident development of regional restoration plans or existing 
    restoration project databases.
    
    Subpart F--Restoration Implementation Phase
    
    Section 990.60--Purpose
    
        Comment: Some commenters noted that the provision requiring Final 
    Restoration Plans in the context of incident-specific assessments is a 
    significant improvement over past proposals, since the current proposal 
    bases the liability claim on projected costs of implementing the Final 
    Restoration Plan, rather than developing a financial payment for 
    liability and then deciding what to do with the money. Some of these 
    commenters had argued that the 1994 proposal, with the Final 
    Restoration Plan being developed in the Post-Assessment Phase, violated 
    OPA by allowing trustees to spend recoveries on non-site-specific 
    restoration actions, i.e., implementing restoration plans other than 
    those developed by the trustees in the assessment phase and that 
    supported the damage claim.
        Response: NOAA agrees that recoveries will be used to implement the 
    restoration plans developed through the assessment, except where new 
    information received after completion of the plan indicates that the 
    plan needs to be modified to conform to the standards of this rule. Any 
    such modification must be made by a public process documented in the 
    administrative record for restoration implementation.
    
    Section 990.61--Administrative Record
    
        Comment: One commenter approved of opening a parallel 
    administrative record for the implementation phase to ensure that there 
    is accurate and complete accountability of all activities and costs. 
    The commenter suggested, however, that the provisions allowing addition 
    of documents to the record is questionable and should be deleted. The 
    commenter noted that the trustees should be required to document their 
    implementation or the responsible party's implementation of the 
    restoration plan, that the monitoring requirements were adhered to, and 
    that cost effective or cost beneficial requirements were followed. The 
    commenter suggested that the rule also should specify the documents 
    expected to be placed in the administrative record by the trustees.
        Response: The final rule restricts augmenting the closed record of 
    assessment except where new information raises significant issues 
    regarding final restoration decisions, is not duplicative of 
    information already in the record, and is offered by an interested 
    party that did not receive actual or constructive notice of the 
    availability of the draft plan. NOAA agrees with the commenter's 
    suggestions to provide some minimum requirements for documents or 
    determinations to be included in the Implementation Phase record, and 
    has amended the rule to include this guidance.
    
    Section 990.62--Presenting a Demand
    
        Comment: Several commenters complained that the rule language is 
    vague in terms of discretion over the form of a demand presented to 
    responsible party. These commenters noted that restoration actions 
    involve management of natural resources and numerous laws at federal, 
    state, tribal, and foreign levels that require that specific agencies 
    maintain the responsibility for decisions involving management of 
    natural resources. The commenters argued that NOAA cannot delegate this 
    responsibility away from trustees to responsible parties. The 
    commenters stated that the trustee should not be required in every case 
    to go first to the responsible party for restoration implementation, 
    but should evaluate, prior to commencing implementation of restoration 
    actions, the most efficient procedure of implementing the plan. This 
    evaluation should include consideration of the responsible party's 
    ability to accomplish effective conduct of the restoration actions.
        Several other commenters strongly supported the provisions allowing 
    the responsible party to either implement the restoration plan or pay 
    damages. The commenters also stated that linking liability to the 
    responsible party's implementation of a plan is a significant 
    improvement over earlier proposals.
        Another commenter asked why there are different standards for 
    allowing a responsible party to implement all or part of an incident-
    specific versus a Regional Restoration Plan.
        Response: The rule does not delegate any essential trustee 
    functions or responsibilities to responsible parties, nor does it 
    create any inalienable rights in responsible parties with respect to 
    implementation of restoration. This provision in the rule recognizes 
    that responsible parties or their agents may be far better equipped to 
    implement restoration promptly and cost-effectively, given certain 
    constraints on governmental spending and contracting authorities. The 
    rule also recognizes that trustees must act responsibly in allowing 
    responsible parties to implement restoration, and this decision 
    regarding participation should be evaluated according to at least the 
    same criteria suggested in Sec. 990.14(c) for determining the scope of 
    responsible party participation in any stage of the assessment. The 
    rule requires trustees to identify performance criteria to gauge the 
    success of restoration efforts, and encourages monitoring and oversight 
    to confirm that restoration actions are carried out as intended in 
    agreements with the responsible party.
        The rule has been amended to remove the unintended differences in 
    standards for responsible party implementation of incident-specific 
    versus regional restoration plans. 
    
    [[Page 494]]
    
    
    Prejudgment Interest
    
        Comment: Several commenters suggested that more flexibility must be 
    added to address those circumstances when a substantial period of time 
    elapses from the date the demand for payment is made to the date 
    payment is actually made; in such cases, trustees should be able to use 
    date of payment as the time to which to discount future costs or 
    inflate ``present'' cost estimates to present value of the restoration 
    action.
        Response: This rule addresses interest up to the point that the 
    formal demand is presented to the responsible parties. Section 1005 of 
    OPA (33 U.S.C. 2705) addresses the payment of pre-judgment interest 
    from the point the demand is made until the claim is paid.
        Comment: Some commenters argued that interest computed on past 
    costs amounts to prejudgment interest and section 1005 of OPA (33 
    U.S.C. 2705) provides that such interest runs only from 30 days after 
    claim is presented and is to be paid at a commercial paper rate. 
    Therefore, the commenters stated that the rule cannot allow recovery of 
    interest on periods prior to demand, which would give trustees 
    prejudgment interest in excess of that which Congress deemed proper.
        Response: NOAA notes that interest recovered on past costs 
    represents lost opportunity costs for the trustees, intended to 
    encourage prompt payment of claims. Such a recovery is not an 
    inappropriate recovery of prejudgment interest.
    
    Section 990.64--Unsatisfied Demands
    
        Comment: Several commenters stated that NOAA should clarify that 
    uncompensated financial damages for compensatory restoration, which is 
    intended to represent compensation for diminution in value, may not be 
    sought from the Oil Spill Liability Trust Fund (Fund); only site-
    specific plans for primary restoration may be paid from that Fund.
        Response: The Oil Spill Liability Trust Fund (Fund) is not 
    available to federal trustees for payment of uncompensated damages 
    under section 1012(a)(4) of OPA (33 U.S.C. 2712(a)(4)) (see Matter of 
    USCG-OSLTF, B-255979, 1995 Comp. Gen. LEXIS 670 (October 30, 1995)). 
    However, federal trustees may seek an appropriation from the Fund for 
    implementation of restoration plans. The rule does not provide for 
    recovery of monetized damages, but does provide for the use of 
    restoration actions that will restore, replace, rehabilitate, or 
    acquire equivalent of interim lost services.
        Comment: Several commenters suggested that the language allowing 
    the responsible party to agree to a demand in order to forestall legal 
    action should be changed to require a responsible party to either pay 
    the demand or enter into an enforceable agreement within 90 calendar 
    days after the trustees present the demand to perform services.
        Response: NOAA agrees that the suggestion is a useful clarification 
    of OPA's requirements in light of the rule's allowance for responsible 
    party implementation of restoration actions.
        Comment: One commenter strongly objected to the requirement that 
    trustees cannot file a civil judicial action until 90 calendar days 
    after presentation of the demand to the responsible party. This 
    commenter argued that this provision has no statutory support, would 
    serve no purpose, and might prove to be a problem for statute of 
    limitations considerations.
        Response: NOAA believes that the contested provision is consistent 
    with the plain meaning of section 1013(c) of OPA (33 U.S.C. 2713(c)).
    
    Section 990.65--Account
    
        Comment: Some commenters suggested that the rule should specify 
    that administrative costs associated with setting up a trustee account 
    are compensable. Some commenters suggested that, if the damage amount 
    is not placed in an interest-bearing account, the rule should allow 
    adjustment to the appropriate state rate.
        Response: NOAA notes that recovery is provided by OPA for costs 
    incurred as a result of an incident. Therefore, the costs associated 
    with setting up accounts are also recoverable. Also, NOAA agrees that 
    adjustments should be made if damages are not placed in an interest-
    bearing account.
        Comment: Some commenters expressed support for the idea of creating 
    separate, interest-bearing accounts to hold recovered sums. One of 
    these commenters, however, stated that joint trust accounts can be a 
    problem between state and federal trustees, if the accounts are 
    required to be registered under a federal court. The commenter 
    suggested that joint recoveries should be exempt from the requirements 
    of the Miscellaneous Receipts Act, and that NOAA should explicitly 
    allow for administration of joint restoration accounts by reputable 
    non-profit organizations that address restoration/replacement/
    acquisition types of activities at local, state, or national levels. 
    Some of these commenters asked for clarification as to why escrow 
    accounts could be used. One commenter stated that interest accrued on 
    these accounts should be required to be used for restoration.
        Response: The rule explicitly allows the use of such accounts. 
    Also, interest earned on recoveries (not including recoveries for past 
    costs incurred) should be used only for restoration.
        Comment: Some commenters strongly encouraged NOAA to provide 
    guidance on implementing accounting procedures, although there was 
    concern that rigorous accounting procedures would be expensive for 
    trustees and thus recovery for accounting costs should be allowed.
        Response: In 1986, EPA implemented Financial Management Procedures 
    for Documenting Superfund Costs. This document is available from the 
    Office of the Comptroller, Financial Management Division, Superfund 
    Accounting Branch. These procedures provide guidance to ensure that 
    documentation of EPA's costs for cleaning up Superfund sites are 
    complete and accurate and can be furnished if litigation is required. 
    These procedures are also relevant guidance to trustees on procedures 
    of recordkeeping that will satisfy the requirement that costs be 
    appropriate/accurate/reasonable. NOAA recognizes that certain expenses 
    are inherent in any cost-tracking system. Recovering such costs as part 
    of the assessment and restoration implementation costs is appropriate 
    since it enables a trustee to demonstrate when, how and where funds for 
    natural resource restoration have been expended, therefore theses costs 
    are recoverable.
        Trustees must maintain appropriate accounting and reporting 
    procedures to keep track of the use of sums recovered. As determined by 
    the trustee, brief reports on the status of the sums recovered and 
    expenditures for particular damage assessment or restoration activities 
    may be reported in the administrative record for the restoration phase.
        Comment: One commenter noted that there is no definition of 
    ``excess damages'' in the proposed rule, and requested that the rule 
    explicitly state that excess damages must not be collected, or, if 
    collected, must be returned to the responsible party.
    
    [[Page 495]]
    
        Response: NOAA believes that damages will never be ``excessive'' or 
    in ``excess'' of the costs needed to restore injured natural resources 
    and/or services if assessments are conducted in accordance with this 
    rule, and restoration is implemented in a timely manner. However, NOAA 
    can envision circumstances where unanticipated environmental conditions 
    require adjustments to restoration actions, conceivably resulting in 
    surplus damages.
        Comment: Several commenters strongly disagreed with the language 
    that requires all excess restoration funds to be placed in the Oil 
    Spill Liability Trust Fund. These commenters noted that damages are 
    generally settled jointly between state and federal trustees and the 
    responsible party and that any excess funding should first be available 
    for additional restoration. The commenters suggested that the 
    responsible party should not expect to recover excess funds unless they 
    are willing to pay additional funding for the restoration cases that 
    result in deficits (e.g., a contingency fee), due to factors beyond the 
    control of the trustees. These commenters recommended, at a minimum, 
    that remaining funds should be deposited in both federal and state 
    response trust funds, where states have such a fund.
        Response: The rule allows for the recovery of damages required by 
    OPA, namely: (1) The cost of restoring, rehabilitating, replacing, or 
    acquiring the equivalent of, the injured natural resources and/or 
    services pending restoration; (2) the diminution in value of those 
    natural resources pending restoration; plus (3) the reasonable cost of 
    assessing those damages. The recovery of those three items is not 
    excess recovery. Trustees are to use the money to restore, 
    rehabilitate, replace, or acquire the equivalent of the injured natural 
    resources and/or services provided by those natural resources and to 
    reimburse the reasonable costs of conducting the assessment. Any 
    recoveries that may be left over after implementing the restoration 
    plan must be deposited in the Oil Spill Liability Trust Fund, in 
    accordance with the provisions of section 1006(f) of OPA (33 U.S.C. 
    2706(f)).
    
    Section 990.66--Additional Considerations
    
        Comment: One commenter suggested that the final rule establish 
    timetables for the development and implementation of restoration plans.
        Response: NOAA disagrees that any time table for developing and 
    implementing restoration plans could have broad enough applicability 
    for all possible incidents without hampering the process for some 
    subset of incidents.
        Comment: Several commenters indicated the importance of monitoring 
    and oversight and the need to plan for failure of a restoration plan. 
    Other commenters argued that monitoring costs are not recoverable 
    because such costs are not mentioned in section 1002 of OPA and, 
    therefore, not intended by the statute.
        Response: As discussed in response to comments on the definition of 
    reasonable assessment costs, NOAA believes that monitoring and 
    oversight costs are recoverable damages. NOAA agrees with the 
    importance of monitoring and oversight and has amended the rule to 
    specifically discuss the purpose and scope of monitoring and oversight 
    activities within the restoration implementation phase.
        Comment: One commenter stated that allowing for reopeners within 
    the rule will make it difficult for businesses to anticipate costs and 
    create proper reserves. Other commenters questioned the degree to which 
    a responsible party could be held accountable for a restoration plan 
    selected by the trustees that did not work, requesting that NOAA 
    reexamine the propriety of reopeners and raised the question as to who 
    should bear the risks inherent in implementing a Restoration Plan. 
    Another commenter suggested that the rule provides no standards for 
    mid-course corrections, but that such standards are needed. One 
    commenter questioned whether a responsible party would be subject to 
    the restoration plan if that responsible party had not been involved in 
    the development of that plan.
        Response: Reopeners may be required to properly ensure that the 
    environment and public are appropriately made whole for the injuries 
    from a particular incident. Thus, reopeners should reflect the degree 
    of certainty in the assessment of the nature and extent of injuries and 
    losses. NOAA also agrees that reopeners must not be used irresponsibly, 
    i.e., holding responsible parties accountable for unknowable 
    consequences for an indeterminate period of time. Trustees must specify 
    criteria upon which restoration actions will be judged successful, so 
    that responsible parties may understand the goals and targets for their 
    actions. Both parties should strive to identify any uncertainties in 
    successful implementation of a plan such that requests for additional 
    actions on the part of the responsible party will not likely result. 
    NOAA has amended the rule to provide some guidance on the nature of 
    performance criteria that trustees should consider in formulating 
    agreements with responsible parties.
        Comment: One commenter suggested that the selection of a lead 
    trustee to coordinate implementation of restoration should be 
    mandatory.
        Response: Section 990.14 of the rule advises identification of a 
    lead administrative trustee, or co-lead administrative trustees, for 
    all phases of a joint assessment.

    Appendix A--Considerations To Facilitate the Restoration Process
    
    I. Pre-Incident Planning
    
    General
        NOAA believes that commitment of time, funding, and personnel to 
    up-front planning prior to an incident will help ensure that the 
    assessment results in appropriate and cost-effective restoration. Thus, 
    trustees are encouraged to develop pre-incident plans.
    Pre-Incident Plan Contents
        NOAA suggests that pre-incident plans:
        (a) Identify natural resource assessment teams. The restoration 
    process requires an interdisciplinary approach to ensure the integrated 
    use of science, economics, and law necessary in planning and 
    implementing restoration. Trustees are encouraged to identify 
    appropriately experienced personnel needed for natural resource 
    assessment teams at the area and regional levels.
        Personnel required for natural resource assessment teams should be 
    appropriate to the scope and scale of the incident and natural 
    resources and/or services injured. For instance, for incidents with 
    complicated or long-term ecological injuries, the core team could 
    include a natural resource trustee coordinator, restoration expert, 
    natural resource biologist, environmental (petroleum) chemist, natural 
    resource economist, quality assurance specialist, data manager/sample 
    custodian, statistician, natural resource attorney, and administrative 
    support specialist. If at all possible, the team should not be ad hoc; 
    members should be knowledgeable about relevant statutes and 
    regulations, and be able to establish a working relationship with the 
    various parties likely to be involved in incidents.
        (b) Establish trustee notification systems. Prompt notification is 
    essential for efficient and effective initiation of the restoration 
    process. Response personnel are required under the NCP to notify 
    trustees whenever natural resources under their jurisdiction or 
    management have been, or are likely to be, injured as a result of an 
    incident.
        Thus, each trustee should establish emergency notification 
    protocols so that the process can be initiated on a 24-hour basis. 
    Notification could be coordinated to minimize the number of calls 
    response personnel must make to the trustees. Notification protocols 
    are also needed within trustee agencies so that appropriate regional 
    and local personnel can be informed of an incident. Area and Regional 
    Contingency Plans should include contact information for each trustee 
    and clear, unambiguous criteria for trustee notification (e.g., all 
    incidents, incidents over a certain size, location, etc.).
        (c) Identify likely support services. In many circumstances, 
    trustees may require specialized contractor support. For example, 
    research vessels may be necessary for sample collection, or outside 
    experts may be necessary to design and conduct studies. If, as part of 
    pre-incident planning, the trustees can identify appropriate support 
    services and pursue contracting procedures that will expedite incident-
    specific hiring of contractors, potentially detrimental delays in the 
    assessment can be avoided during incidents.
        The types of support and expertise expected to be needed, as well 
    as potential contractor and expert names, should be identified as part 
    of pre-incident planning. Contracts should be established to allow 
    rapid acquisition of contractor services. Identified contractors may 
    even be called on to participate in pre-incident planning so that all 
    parties are familiar with the specific needs of the restoration 
    process.
        Backup services should also be identified since the needs of both 
    response and natural resource activities can exceed even regional 
    capabilities.
        (d) Identify natural resources and services at risk. In the NCP, 
    regional and area planning committees are responsible for the 
    identification of natural resources under their jurisdiction that are 
    potentially vulnerable to incidents for given geographic areas such as 
    wetland habitats near oil terminals or bird rookeries near shipping 
    routes. If there is an incident, the response teams will focus their 
    efforts on protection of these natural resources and/or services 
    considered most vulnerable.
        Trustees should actively participate in such planning committees to 
    identify natural resources and services at risk. Further, trustees 
    should identify and evaluate possible assessment procedures for these 
    natural resources and services.
        (e) Identify area and regional response agencies and officials. In 
    order to participate actively in area and regional planning activities, 
    trustees should identify the response agencies and officials. 
    Developing a working relationship with these response agencies and 
    officials will optimize coordination between assessment and response 
    activities following an incident.
        (f) Identify available baseline and other relevant information. 
    Trustees should identify and catalog sources of baseline information as 
    part of pre-incident planning, including seeking input on sources of 
    information. Types of information that may be important include: (i) 
    Petroleum hydrocarbon contamination in indicator organisms; (ii) 
    species census and inventory data; (iii) baseline data on species 
    populations; (iv) recreational use statistics; (v) values for selected 
    natural resources and services; and (vi) restoration measures 
    applicable to injured natural resources and services. Familiarity with 
    the types of baseline information and identification of data gaps and 
    needs will allow the trustees to formulate better study designs and 
    restoration approaches.
        (g) Establish data management systems. Data management and record 
    keeping are critical throughout the restoration process. Data 
    management systems may best be designed during pre-incident planning to 
    minimize the possibility of losing critical information during an 
    incident. For small incidents, this may be a relatively simple filing 
    system, but for large incidents, a centralized computer-based system 
    may be essential.
        Trustees may decide to develop consistent data management formats, 
    such as field, laboratory and quality assurance forms, to facilitate 
    data management. At a minimum, data management should address the: (i) 
    Type and volume of data; (ii) uses and users of the data; (iii) 
    availability of existing data management structures; (iv) quality 
    assurance needs; (v) reporting requirements; and (vi) accessibility of 
    the data. Data management should also include provisions for 
    distribution of updates for the trustees and others on a timely basis; 
    and 
    
    [[Page 497]]
    
        (h) Identify assessment funding issues and options. Funding of 
    trustee activities should be addressed during pre-incident planning 
    because of the need to initiate actions expeditiously after an 
    incident. Trustees may have several sources of potential funding, 
    including: (i) Responsible parties; (ii) Oil Spill Liability Trust Fund 
    (Fund); and (iii) agency funding. Trustees should consult the most up-
    to-date guidance available from the U.S. Coast Guard for access to the 
    Fund and incorporate these procedures into pre-incident planning.
    
    II. Regional Restoration Planning
    
    General
        OPA emphasizes making the environment and public whole for injuries 
    to natural resources and services. Where practicable, incident-specific 
    restoration plan development is the preferred approach. However, for 
    many incidents, such incident-specific planning may be impractical 
    because, for instance, injuries are not extensive or are short-term. 
    For small incidents, incident-specific planning costs may be high 
    compared to the estimated damages.
        Thus, to achieve OPA's mandate to make the environment and public 
    whole, trustees are strongly encouraged to use or modify existing 
    restoration plans, identify other existing restoration projects, or 
    develop new regional restoration plans. Such regional planning is 
    appropriate so long as natural resources and services comparable to 
    those expected to be injured by an incident are addressed in the plans.
     Availability of Regional Restoration Plans
        Trustees may rely on or adjust existing regional restoration plans, 
    so long as they have followed or can be modified to meet the planning 
    requirements under the rule. Lacking existing regional plans, trustees 
    should seek to develop such plans. The trustees may organize these 
    plans based on such factors as geography (e.g., ecosystems or 
    watersheds), injuries anticipated from incidents, or restoration 
    alternatives.
        Regional restoration plans must be developed or annotated in such a 
    way that trustees are able to justify linking the injuries from a 
    particular incident or set of incidents with a specific restoration 
    project or set of projects within the plan. This may be facilitated by 
    describing the types of injuries anticipated from incidents to specific 
    natural resources within a region, and describing these injuries in 
    terms of the types and importance of functions and services, ecological 
    and human use.
    
    III. Coordination
    
    General
        Trustee coordination is crucial to an efficient and effective 
    assessment and restoration planning process because of the need to 
    address shared trustee interests in natural resources and services 
    injured by incidents. OPA prohibits double recovery of damages, which 
    strongly suggests that, where multiple trustees are involved in an 
    incident, they actively coordinate their activities as early in the 
    process as possible.
    Incentives for Coordination
        Incentives for coordination include:
        (a) Access to funding--requests for reimbursement of the costs of 
    initiating natural resource damage assessment from the Fund require 
    that trustees attempt to coordinate their assessments and funding 
    requests;
        (b) Conflict resolution--lack of coordination among the trustees or 
    with the responsible parties will likely produce an adversarial, 
    litigation-charged atmosphere. A joint trustee-responsible party effort 
    will help resolve legal, administrative, and technical conflicts; and
        (c) Pooling limited resources--a joint trustee-responsible party 
    effort will allow the pooling of financial and human resources for more 
    efficient and effective restoration planning and implementation.
        Trustees will benefit greatly if coordination procedures can be 
    established well before an incident occurs. However, cooperative 
    arrangements allowing for responsible party implementation of 
    assessment activities are subject to trustee oversight because of the 
    trustees' fiduciary responsibility to the public.
    Agreements
        Trustees should consider Memoranda of Understanding (MOUs) to 
    formalize their co-trustee relationships. The MOU or similar agreements 
    may be prepared either in anticipation of an incident or shortly after 
    an incident. It is important that trustee agreements address, at a 
    minimum: the purpose of the agreement; trustee participants; trustee 
    organization; trustee responsibilities; and a decisionmaking process.
    Lead Administrative Trustee (LAT)
        When conducting joint assessments under this rule, trustees must 
    designate a Lead Administrative Trustee (LAT). The LAT serves as the 
    contact for trustee interaction with response agencies, responsible 
    parties and the public, and provides general administrative support to 
    the restoration process.
        The rule does not require that a LAT be a federal agency. However, 
    when more than one federal trustee(s) is involved, the federal trustees 
    must select a federal LAT if the trustees wish to access the Fund to 
    initiate natural resource damage assessment activities. Where 
    appropriate, the trustees may designate co-LATs, consisting of a 
    federal LAT and the state, tribal, or foreign trustees. Trustees may 
    also elect to provide for sequential LATs to cover different stages of 
    the restoration planning and implementation process.
        The LAT should be selected by mutual agreement of the trustees. In 
    designating a LAT, trustees may want to consider such factors as: 
    relative extent of jurisdiction over natural resources and services 
    injured by an incident; capability and willingness to conduct 
    assessment actions; and sequence and duration of involvement in the 
    incident or similar incidents. Selection of a LAT should be made as 
    soon as practicable after notification of an incident.
    Co-Trustee Responsibilities
        Co-trustees should be prepared to participate fully in the 
    restoration planning and implementation process by: participating in or 
    conducting those studies or analyses for which they have special 
    expertise or management authority; making staff available to 
    participate in other assessment activities, in particular, to represent 
    the trustee in decisions requiring co-trustee unanimity; and committing 
    financial resources. Each trustee may limit this participation based on 
    the extent of injury to its natural resources as well as legal and 
    financial constraints.
    Coordination With Response Agencies
        To the fullest extent practicable without interfering with response 
    activities, natural resource concerns should be integrated with 
    response activities before pursuing an assessment; liability for 
    natural resource damages is limited to damages for injuries residual to 
    the response phase, plus any injuries related to the response. NOAA 
    strongly encourages trustees to coordinate natural resource injury 
    assessment activities, such as gathering ephemeral data related to an 
    incident, with response actions. Mechanisms to coordinate response and 
    trustee data gathering needs and processes may also be addressed in 
    pre-incident planning. 
    
    [[Page 498]]
    
    Coordination With the Responsible Parties
        Under OPA, trustees have the responsibility to determine 
    appropriate actions to restore injured natural resources and services. 
    However, the rule requires trustees to invite the responsible parties 
    to be full or partial participants in the assessment and restoration 
    process, whenever it can be achieved without compromise of the 
    trustees' statutory obligations to act on behalf of the public trust.
    Enforceable Agreements
        Trustees and responsible parties should consider entering into 
    agreements to facilitate their interactions and resolve any disputes 
    during the assessment. To maximize cost-effectiveness and cooperation, 
    trustees and responsible parties should attempt to develop a set of 
    agreed-upon facts concerning the incident, assessment, and/or 
    restoration. For example, stipulated facts might concern the types of 
    natural resources and services injured, the extent of injury, or the 
    most appropriate assessment procedures to determine injury and/or 
    restoration needs, and how the results of the procedures used will be 
    interpreted.
    Coordination Among the Responsible Parties
        While it is obviously not as easy to identify the mix of potential 
    responsible parties that will participate in a given incident, there 
    are issues that can be addressed in general terms by the potential 
    responsible parties in advance, that will enable them to enter the 
    cooperative restoration process more efficiently and effectively. In an 
    incident with a single well-identified responsible party, the ability 
    to assess the situation, identify the appropriate course of action and 
    most effectively implement a cooperative response will be improved by 
    pre-incident planning. In an incident with multiple potential 
    responsible parties, the need for pre-incident planning is more 
    apparent. In this latter situation, the potential responsible parties 
    need to consider the efficacy of a cooperative restoration process, and 
    the terms under which they would consider entering into such a process.
    
    Appendix B--Assessment Procedures
    
        Any procedures used to assess injury and scale restoration actions 
    (i.e., procedures used throughout the natural resource damage 
    assessment) must meet all of the standards listed in Sec. 990.27 of the 
    rule if they are to be in accordance with the rule. The rule allows for 
    the use of a range of assessment procedures. The scientific and 
    technical adequacy of these procedures will be judged based on the 
    circumstances of the incident and associated injuries, and the 
    information needed to determine restoration actions. If a range of 
    assessment procedures providing the same type and quality of 
    information is available, the least costly procedure must be used.
    Type A Procedures
        The Department of the Interior (DOI) is responsible for developing 
    ``type A'' assessment procedures under CERCLA. These procedures were 
    originally intended to cover both hazardous substance releases as well 
    as oil discharges. This rule would allow trustees to use any final type 
    A procedure incorporated into DOI's regulations that addresses 
    discharges of oil.
    
    Compensation Formulas
    
        As part of the 1994 proposed regulations, NOAA proposed a 
    compensation formula that could be used for small incidents in both the 
    estuarine and marine environments and the Great Lakes (and other inland 
    waters). The formula was developed using early drafts of type A models 
    being developed by DOI. The purpose of the formula is to readily 
    estimate impacts based on the amount of oil discharged and several 
    simple data inputs. The compensation formula was reserved in the 1995 
    proposed rule.
        DOI is scheduled to issue the final revised type A models in early 
    1996. When those models are final, NOAA intends to reissue the 
    compensation formulas. Pending the final promulgation of the models, 
    NOAA has developed a guidance document to provide an interim tool for 
    such a purpose.
        The compensation formula guidance document is intended to provide 
    instructions on how to recreate the incident scenarios used to develop 
    the 1994 proposed estuarine/marine compensation formulas. Using the 
    data in the guidance document, trustees will have a cost-effective tool 
    to use in estimating expected impacts of most discharges of oil. This 
    information may prove to be useful in early decisionmaking in a natural 
    resource damage assessment or in settlement discussions.
    
    Restoration Scaling Procedures
    
        The following is a list of procedures that are mentioned in this 
    preamble as potential approaches to scaling restoration actions. The 
    trustees are not limited to these procedures and may use any procedure 
    deemed to be appropriate to the particular situation, pursuant to the 
    guidance given above and in Sec. 990.27 of the final rule.
    A. Habitat Equivalency Analysis
        This procedure may be used to scale restoration actions that 
    replace entire habitats that support multiple species or that replace 
    individual species that provide a variety of natural resource services. 
    To ensure that the scale of the restoration action does not over- or 
    under-compensate the public for injuries incurred, the trustees must 
    establish an equivalency between the present value of the quantity of 
    lost services and the present value of the quantity of services 
    provided by the restoration action(s) over time.
    B. Travel Cost Method
        The travel cost method is principally employed to model demand for 
    recreational experiences. This measurement procedure evolved from the 
    insight that the travel costs an individual incurs to visit a site are 
    like a price for the site visit. In essence, the travel cost method 
    assesses an individual's willingness to travel further (thereby 
    incurring higher travel costs) in order to recreate at more highly 
    valued sites. It is important to take into account the availability and 
    quality of substitute recreation sites. Multiple-site models of 
    recreational demand, such as the random utility model, focus attention 
    on the recreationist's choice among alternative recreational sites. 
    This version of the travel cost model is particularly appropriate where 
    many substitutes are available to the individual and/or when the 
    incident has affected quality at multiple sites. For this reason, 
    multiple-site models of recreational demand are preferred to single-
    site models, unless it is feasible to include in the single-site model 
    price and quality information about the relevant substitute sites (or 
    there are no substitute sites). If a literature value from a single-
    site model, without full accounting for substitutes, is the only 
    available estimate, an appropriate adjustment should be made to the 
    estimate of trip value.
        In cases where the change in the quantity or quality of natural 
    resource services to be analyzed is outside of the range of observed 
    behavior, trustees may choose to collect contingent behavior data. 
    Contingent behavior refers to the behavior of users or potential users 
    of a natural resource service under hypothetical conditions presented 
    to them in the travel cost survey.
    
    [[Page 499]]
    
    C. Factor Income Approach
        This approach can be employed to calculate changes in economic rent 
    under certain special conditions; in more general cases, the procedure 
    appropriate for calculating economic rent is market models of supply 
    and demand. The factor income approach relies upon the production 
    function model that relates the contribution of inputs to the 
    production of an output. (Inputs are also referred to as factors of 
    production.) An incident may decrease the quality and/or quantity of a 
    natural resource, and thereby effectively increase the cost of 
    employing a natural resource input in a production process. For 
    example, contamination of water supplies or of sediments in 
    navigational waterways may increase the costs of providing drinking 
    water or of maintaining navigational waterways through dredging. Where 
    the prices of the final product and of the other factors of production 
    do not change, the change in economic rent is simply the sum of the 
    changes in factor costs (or factor income) for the affected inputs.
    D. Hedonic Price Model
        The hedonic price model relates the price of a marketed commodity 
    to its various attributes. In the natural resource damage assessment 
    context, it may be used to determine the change in value of some 
    nonmarket services from public trust natural resources (for example, 
    environmental amenities such as water or air quality) where they 
    function as attributes of private market goods, such as property. For 
    example, the value of beach front property may be directly related to 
    the quality and accessibility of the adjacent coastline. The change in 
    value of the property owners associated with the reduction in the 
    quality or accessibility, as may occur due to an incident, may be 
    captured in the value of the property if the effect is large enough. 
    All else equal, the decrease in property values as a result of a 
    discharge measures the change in use value of the injured coastline 
    natural resources accruing to local property owners. This measure of 
    the reduction in value of coastline natural resources will not capture 
    any loss in value of the natural resources that may accrue to members 
    of the public who do not own property in the area.
    E. Market Models of Demand and Supply
        For those goods and services regularly traded in markets, 
    economists typically rely upon market transactions to reveal the values 
    that individuals place on the goods and services and the costs of 
    producing them. When the quality of the natural resource directly 
    affects the value individual consumers place on a good or service, the 
    correct measure of damage is the change in consumer surplus, or 
    individuals' willingness-to-accept compensation plus the economic rent 
    component of producer surplus, if any, for the injuries associated with 
    the discharge.
    F. Contingent Valuation
        The contingent valuation (CV) method determines the value of goods 
    and services based on the results of carefully designed surveys. The CV 
    method obtains an estimate of the total value, including both direct 
    and passive use values of a good or service by using a questionnaire 
    designed to objectively collect information about the respondent's 
    willingness to pay for the good or service. A CV survey contains three 
    basic elements: (i) A description of the good/service to be valued and 
    the context in which it will be provided, including the method of 
    payment; (ii) questions regarding the respondent's willingness to pay 
    for the good or service; and (iii) questions concerning demographics or 
    other characteristics of the respondent to interpret and validate 
    survey responses.
    G. Conjoint Analysis
        Conjoint analysis is a survey procedure that is used to derive the 
    values of particular attributes of goods or services. Information is 
    collected about individuals' choices between different goods that vary 
    in terms of their attributes or service levels. With this information, 
    it is possible to derive values for each particular attribute or 
    service. If price is included as an attribute in the choice scenarios, 
    values can be derived in terms of dollars which can be used with the 
    valuation approach.
        Alternatively, it is possible to value attributes in terms of units 
    of replacement services. Survey respondents would be presented with 
    choices between two or more options that may represent restoration 
    actions with varying levels or types of services. The goal is to obtain 
    the value of the injured services in terms of alternative natural 
    resource services so that restoration actions can be scaled directly 
    using the resource-to-resource or service-to-service approaches or the 
    valuation approach.
    H. Benefits Transfer Approach
        Benefits (or valuation) transfer involves the application of 
    existing value estimates or valuation functions and data that were 
    developed in one context to address a sufficiently similar natural 
    resource valuation question in a different context.
        Where natural resource values have been developed through an 
    administrative or legislative process and are relevant and reliable 
    under the circumstances, the trustees may use these values, as 
    appropriate, in a benefits transfer context. Other values may be used 
    so long as three basic issues are considered in determining the 
    appropriateness of their use: the comparability of the users and of the 
    natural resource and/or service being valued in the initial studies and 
    the transfer context; the comparability of the change in quality or 
    quantity of natural resources and/or services in the initial study and 
    in the transfer context (where relevant); and the quality of the 
    studies being transferred.
    
    National Environmental Policy Act, Regulatory Flexibility Act, 
    Paperwork Reduction Act and Executive Orders 12630, 12778, and 12612
    
        The National Oceanic and Atmospheric Administration has determined 
    that this rule does not constitute a major federal action significantly 
    affecting the quality of the human environment. Therefore, no further 
    analysis pursuant to section 102(2)(C) of the National Environmental 
    Policy Act of 1969 (42 U.S.C. 4332(2)(C)) has been prepared.
        The Assistant General Counsel for Legislation and Regulation, in 
    accordance with the Regulatory Flexibility Act, certifies to the Chief 
    Counsel for Advocacy, Small Business Administration, that this rule 
    will not have a significant economic effect on a substantial number of 
    small entities. The rule is intended to make more specific, and easier 
    to apply, the standards set out in OPA for assessing injury to natural 
    resources and/or services as a result of actual or threatened 
    discharges of oil. The rule is not intended to change the balance of 
    legal benefits and responsibilities among any parties or groups, large 
    or small. To the extent any are affected by the rule, it is anticipated 
    that all parties will benefit by increased ease of application of law 
    in this area.
        It has been determined that this rule does not contain information 
    collection requirements that require approval by the Office of 
    Management and Budget under the Paperwork Reduction Act (44 U.S.C. 3501 
    et seq.).
        The final rule has been reviewed under Executive Order 12,866 and 
    has been determined to constitute a significant regulatory action. 
    However, because of the difficulty of evaluating 
    
    [[Page 500]]
    the effects of alternatives to this rule, the Office of Information and 
    Regulatory Affairs within the Office of Management and Budget has 
    waived preparation of the assessments described in sections 6(a)(3)(B) 
    and 6(a)(3(C) of Executive Order 12,866 for the final rule.
        It has been determined that this rule does not have takings 
    implications under Executive Order 12,630. The Department has certified 
    to the Office of Management and Budget that this rule meets the 
    applicable standards provided in sections 2(a) and 2(b)(2) of Executive 
    Order 12,778. It has been determined that this rule does not have 
    federalism implications under Executive Order 12,612.

    Subpart A--Introduction
    
    
    Sec. 990.10  Purpose.
    
        The goal of the Oil Pollution Act of 1990 (OPA), 33 U.S.C. 2701 et 
    seq., is to make the environment and public whole for injuries to 
    natural resources and services resulting from an incident involving a 
    discharge or substantial threat of a discharge of oil (incident).
        This goal is achieved through the return of the injured natural 
    resources and services to baseline and compensation for interim losses 
    of such natural resources and services from the date of the incident 
    until recovery. The purpose of this part is to promote expeditious and 
    cost-effective restoration of natural resources and services injured as 
    a result of an incident. To fulfill this purpose, this part provides a 
    natural resource damage assessment process for developing a plan for 
    restoration of the injured natural resources and services and pursuing 
    implementation or funding of the plan by responsible parties. This part 
    also provides an administrative process for involving interested 
    parties in the assessment, a range of assessment procedures for 
    identifying and evaluating injuries to natural resources and services, 
    and a means for selecting restoration actions from a reasonable range 
    of alternatives.
    
    
    Sec. 990.11  Scope.
    
        The Oil Pollution Act of 1990 (OPA), 33 U.S.C. 2701 et seq., 
    provides for the designation of federal, state, and, if designated by 
    the Governor of the state, local officials to act on behalf of the 
    public as trustees for natural resources and for the designation of 
    Indian tribe and foreign officials to act as trustees for natural 
    resources on behalf of, respectively, the tribe or its members and the 
    foreign government. This part may be used by these officials in 
    conducting natural resource damage assessments when natural resources 
    and/or services are injured as a result of an incident involving an 
    actual or substantial threat of a discharge of oil. This part is not 
    intended to affect the recoverability of natural resource damages when 
    recoveries are sought other than in accordance with this part.
    
    
    Sec. 990.12  Overview.
    
        This part describes three phases of a natural resource damage 
    assessment. The Preassessment Phase, during which trustees determine 
    whether to pursue restoration, is described in subpart D of this part. 
    The Restoration Planning Phase, during which trustees evaluate 
    information on potential injuries and use that information to determine 
    the need for, type of, and scale of restoration, is described in 
    subpart E of this part. The Restoration Implementation Phase, during 
    which trustees ensure implementation of restoration, is described in 
    subpart F of this part.
    
    
    Sec. 990.13  Rebuttable presumption.
    
        Any determination or assessment of damages to natural resources 
    made by a Federal, State, or Indian trustee in accordance with this 
    part shall have the force and effect of a rebuttable presumption on 
    behalf of the trustee in any administrative or judicial proceeding 
    under OPA.
    
    
    Sec. 990.14  Coordination.
    
        (a) Trustees. (1) If an incident affects the interests of multiple 
    trustees, the trustees should act jointly under this part to ensure 
    that full restoration is achieved without double recovery of damages. 
    For joint assessments, trustees must designate one or more Lead 
    
    [[Page 501]]
    Administrative Trustee(s) to act as coordinators.
        (2) If there is a reasonable basis for dividing the natural 
    resource damage assessment, trustees may act independently under this 
    part, so long as there is no double recovery of damages.
        (3) Trustees may develop pre-incident or incident-specific 
    memoranda of understanding to coordinate their activities.
        (b) Response agencies. Trustees must coordinate their activities 
    conducted concurrently with response operations with response agencies 
    consistent with the NCP and any pre-incident plans developed under 
    Sec. 990.15(a) of this part. Trustees may develop pre-incident 
    memoranda of understanding to coordinate their activities with response 
    agencies.
        (c) Responsible parties--(1) Invitation. Trustees must invite the 
    responsible parties to participate in the natural resource damage 
    assessment described in this part. The invitation to participate should 
    be in writing, and a written response by the responsible parties is 
    required to confirm the desire to participate.
        (2) Timing. The invitation to participate should be extended to 
    known responsible parties as soon as practicable, but not later than 
    the delivery of the ``Notice of Intent to Conduct Restoration 
    Planning,'' under Sec. 990.44 of this part, to the responsible party.
        (3) Agreements. Trustees and responsible parties should consider 
    entering into binding agreements to facilitate their interactions and 
    resolve any disputes during the assessment. To maximize cost-
    effectiveness and cooperation, trustees and responsible parties should 
    attempt to develop a set of agreed-upon facts concerning the incident 
    and/or assessment.
        (4) Nature and extent of participation. If the responsible parties 
    accept the invitation to participate, the scope of that participation 
    must be determined by the trustees, in light of the considerations in 
    paragraph (c)(5) of this section. At a minimum, participation will 
    include notice of trustee determinations required under this part, and 
    notice and opportunity to comment on documents or plans that 
    significantly affect the nature and extent of the assessment. Increased 
    levels of participation by responsible parties may be developed at the 
    mutual agreement of the trustees and the responsible parties. Trustees 
    will objectively consider all written comments provided by the 
    responsible parties, as well as any other recommendations or proposals 
    that the responsible parties submit in writing to the Lead 
    Administrative Trustee. Submissions by the responsible parties will be 
    included in the administrative record. Final authority to make 
    determinations regarding injury and restoration rest solely with the 
    trustees. Trustees may end participation by responsible parties who, 
    during the conduct of the assessment, in the sole judgment of the 
    trustees, cause interference with the trustees' ability to fulfill 
    their responsibilities under OPA and this part.
        (5) Considerations. In determining the nature and extent of 
    participation by the responsible parties or their representatives, 
    trustees may consider such factors as:
        (i) Whether the responsible parties have been identified;
        (ii) The willingness of responsible parties to participate in the 
    assessment;
        (iii) The willingness of responsible parties to fund assessment 
    activities;
        (iv) The willingness and ability of responsible parties to conduct 
    assessment activities in a technically sound and timely manner and to 
    be bound by the results of jointly agreed upon studies;
        (v) The degree of cooperation of the responsible parties in the 
    response to the incident; and
        (vi) The actions of the responsible parties in prior assessments.
        (6) Request for alternative assessment procedures. (i) The 
    participating responsible parties may request that trustees use 
    assessment procedures other than those selected by the trustees if the 
    responsible parties:
        (A) Identify the proposed procedures to be used that meet the 
    requirements of Sec. 990.27 of this part, and provide reasons 
    supporting the technical adequacy and appropriateness of such 
    procedures for the incident and associated injuries;
        (B) Advance to the trustees the trustees' reasonable estimate of 
    the cost of using the proposed procedures; and
        (C) Agree not to challenge the results of the proposed procedures. 
    The request from the responsible parties may be made at any time, but 
    no later than, fourteen (14) days of being notified of the trustees' 
    proposed assessment procedures for the incident or the injury.
        (ii) Trustees may reject the responsible parties' proposed 
    assessment procedures if, in the sole judgment of the trustees, the 
    proposed assessment procedures:
        (A) Are not technically feasible;
        (B) Are not scientifically or technically sound;
        (C) Would inadequately address the natural resources and services 
    of concern;
        (D) Could not be completed within a reasonable time frame; or
        (E) Do not meet the requirements of Sec. 990.27 of this part.
        (7) Disclosure. Trustees must document in the administrative record 
    and Restoration Plan the invitation to the responsible parties to 
    participate, and briefly describe the nature and extent of the 
    responsible parties' participation. If the responsible parties' 
    participation is terminated during the assessment, trustees must 
    provide a brief explanation of this decision in the administrative 
    record and Restoration Plan.
        (d) Public. Trustees must provide opportunities for public 
    involvement after the trustees' decision to develop restoration plans 
    or issuance of any notices to that effect, as provided in Sec. 990.55 
    of this part. Trustees may also provide opportunities for public 
    involvement at any time prior to this decision if such involvement may 
    enhance trustees' decisionmaking or avoid delays in restoration.
    
    
    Sec. 990.15  Considerations to facilitate restoration.
    
        In addition to the procedures provided in subparts D through F of 
    this part, trustees may take other actions to further the goal of 
    expediting restoration of injured natural resources and services, 
    including:
        (a) Pre-incident planning. Trustees may engage in pre-incident 
    planning activities. Pre-incident plans may identify natural resource 
    damage assessment teams, establish trustee notification systems, 
    identify support services, identify natural resources and services at 
    risk, identify area and regional response agencies and officials, 
    identify available baseline information, establish data management 
    systems, and identify assessment funding issues and options. 
    Potentially responsible parties, as well as all other members of the 
    public interested in and capable of participating in assessments, 
    should be included in pre-incident planning to the fullest extent 
    practicable.
        (b) Regional Restoration Plans. Where practicable, incident-
    specific restoration plan development is preferred, however, trustees 
    may develop Regional Restoration Plans. These plans may be used to 
    support a claim under Sec. 990.56 of this part. Regional restoration 
    planning may consist of compiling databases that identify, on a 
    regional or watershed basis, or otherwise as appropriate, existing, 
    planned, or proposed restoration projects that may 
    
    [[Page 502]]
    provide appropriate restoration alternatives for consideration in the 
    context of specific incidents.
    
    Subpart B--Authorities
    
    
    Sec. 990.20  Relationship to the CERCLA natural resource damage 
    assessment regulations.
    
        (a) General. Regulations for assessing natural resource damages 
    resulting from hazardous substance releases under the Comprehensive 
    Environmental Response, Compensation, and Liability Act of 1980, as 
    amended (CERCLA), 42 U.S.C. 9601 et seq., and the Federal Water 
    Pollution Control Act (Clean Water Act), 33 U.S.C. 1321 et seq., are 
    codified at 43 CFR part 11. The CERCLA regulations originally applied 
    to natural resource damages resulting from oil discharges as well as 
    hazardous substance releases. This part supersedes 43 CFR part 11 with 
    regard to oil discharges covered by OPA.
        (b) Assessments commenced before February 5, 1996. If trustees 
    commenced a natural resource damage assessment for an oil discharge 
    under 43 CFR part 11 prior to February 5, 1996 they may complete the 
    assessment in compliance with 43 CFR part 11, or they may elect to use 
    this part, and obtain a rebuttable presumption.
        (c) Oil and hazardous substance mixtures. For natural resource 
    damages resulting from a discharge or release of a mixture of oil and 
    hazardous substances, trustees must use 43 CFR part 11 in order to 
    obtain a rebuttable presumption.
    
    
    Sec. 990.21  Relationship to the NCP.
    
        This part provides procedures by which trustees may determine 
    appropriate restoration of injured natural resources and services, 
    where such injuries are not fully addressed by response actions. 
    Response actions and the coordination with damage assessment activities 
    are conducted pursuant to the National Oil and Hazardous Substances 
    Pollution Contingency Plan (NCP), 40 CFR part 300.
    
    
    Sec. 990.22  Prohibition on double recovery.
    
        When taking actions under this part, trustees are subject to the 
    prohibition on double recovery, as provided in 33 U.S.C. 2706(d)(3) of 
    OPA.
    
    
    Sec. 990.23  Compliance with NEPA and the CEQ regulations.
    
        (a) General. The National Environmental Policy Act (NEPA), 42 
    U.S.C. 4321 et seq. and Council on Environmental Quality (CEQ) 
    regulations implementing NEPA, 40 CFR chapter V, apply to restoration 
    actions by federal trustees, except where a categorical exclusion or 
    other exception to NEPA applies. Thus, when a federal trustee proposes 
    to take restoration actions under this part, it must integrate this 
    part with NEPA, the CEQ regulations, and NEPA regulations promulgated 
    by that federal trustee agency. Where state NEPA-equivalent laws may 
    apply to state trustees, state trustees must consider the extent to 
    which they must integrate this part with their NEPA-equivalent laws. 
    The requirements and process described in this section relate only to 
    NEPA and federal trustees.
        (b) NEPA requirements for federal trustees. NEPA becomes applicable 
    when federal trustees propose to take restoration actions, which begins 
    with the development of a Draft Restoration Plan under Sec. 990.55 of 
    this part. Depending upon the circumstances of the incident, federal 
    trustees may need to consider early involvement of the public in 
    restoration planning in order to meet their NEPA compliance 
    requirements.
        (c) NEPA process for federal trustees. Although the steps in the 
    NEPA process may vary among different federal trustees, the process 
    will generally involve the need to develop restoration plans in the 
    form of an Environmental Assessment or Environmental Impact Statement, 
    depending upon the trustee agency's own NEPA regulations.
        (1) Environmental Assessment. (i) Purpose. The purpose of an 
    Environmental Assessment (EA) is to determine whether a proposed 
    restoration action will have a significant (as defined under NEPA and 
    Sec. 1508.27 of the CEQ regulations) impact on the quality of the human 
    environment, in which case an Environmental Impact Statement (EIS) 
    evaluating the impact is required. In the alternative, where the impact 
    will not be significant, federal trustees must issue a Finding of No 
    Significant Impact (FONSI) as part of the restoration plans developed 
    under this part. If significant impacts to the human environment are 
    anticipated, the determination to proceed with an EIS may be made as a 
    result, or in lieu, of the development of the EA.
        (ii) General steps. (A) If the trustees decide to pursue an EA, the 
    trustees may issue a Notice of Intent to Prepare a Draft Restoration 
    Plan/EA, or proceed directly to developing a Draft Restoration Plan/EA.
        (B) The Draft Restoration Plan/EA must be made available for public 
    review before concluding a FONSI or proceeding with an EIS.
        (C) If a FONSI is concluded, the restoration planning process 
    should be no different than under Sec. 990.55 of this part, except that 
    the Draft Restoration Plan/EA will include the FONSI analysis.
        (D) The time period for public review on the Draft Restoration 
    Plan/EA must be consistent with the federal trustee agency's NEPA 
    requirements, but should generally be no less than thirty (30) calendar 
    days.
        (E) The Final Restoration Plan/EA must consider all public comments 
    on the Draft Restoration Plan/EA and FONSI.
        (F) The means by which a federal trustee requests, considers, and 
    responds to public comments on the Draft Restoration Plan/EA and FONSI 
    must also be consistent with the federal agency's NEPA requirements.
        (2) Environmental Impact Statement. (i) Purpose. The purpose of an 
    Environmental Impact Statement (EIS) is to involve the public and 
    facilitate the decisionmaking process in the federal trustees' analysis 
    of alternative approaches to restoring injured natural resources and 
    services, where the impacts of such restoration are expected to have 
    significant impacts on the quality of the human environment.
        (ii) General steps. (A) If trustees determine that restoration 
    actions are likely to have a significant (as defined under NEPA and 
    Sec. 1508.27 of the CEQ regulations) impact on the environment, they 
    must issue a Notice of Intent to Prepare a Draft Restoration Plan/EIS. 
    The notice must be published in the Federal Register.
        (B) The notice must be followed by formal public involvement in the 
    development of the Draft Restoration Plan/EIS.
        (C) The Draft Restoration Plan/EIS must be made available for 
    public review for a minimum of forty-five (45) calendar days. The Draft 
    Restoration Plan/EIS, or a notice of its availability, must be 
    published in the Federal Register.
        (D) The Final Restoration Plan/EIS must consider all public 
    comments on the Draft Restoration Plan/EIS, and incorporate any changes 
    made to the Draft Restoration Plan/EIS in response to public comments.
        (E) The Final Restoration Plan/EIS must be made publicly available 
    for a minimum of thirty (30) calendar days before a decision is made on 
    the federal trustees' proposed restoration actions (Record of 
    Decision). The Final Restoration Plan/EIS, or a notice of its 
    availability, must be published in the Federal Register.
        (F) The means by which a federal trustee agency requests, 
    considers, and responds to public comments on the 
    
    [[Page 503]]
    Final Restoration Plan/EIS must also be consistent with the federal 
    agency's NEPA requirements.
        (G) After appropriate public review on the Final Restoration Plan/
    EIS is completed, a Record of Decision (ROD) is issued. The ROD 
    summarizes the trustees' decisionmaking process after consideration of 
    any public comments relative to the proposed restoration actions, 
    identifies all restoration alternatives (including the preferred 
    alternative(s)), and their environmental consequences, and states 
    whether all practicable means to avoid or minimize environmental harm 
    were adopted (e.g., monitoring and corrective actions). The ROD may be 
    incorporated with other decision documents prepared by the trustees. 
    The means by which the ROD is made publicly available must be 
    consistent with the federal trustee agency's NEPA requirements.
        (d) Relationship to Regional Restoration Plans or an existing 
    restoration project. If a Regional Restoration Plan or existing 
    restoration project is proposed for use, federal trustees may be able 
    to tier their NEPA analysis to an existing EIS, as described in 
    Secs. 1502.20 and 1508.28 of the CEQ regulations.

    Sec. 990.25  Settlement.
    
        Trustees may settle claims for natural resource damages under this 
    part at any time, provided that the settlement is adequate in the 
    judgment of the trustees to satisfy the goal of OPA and is fair, 
    reasonable, and in the public interest, with particular consideration 
    of the adequacy of the settlement to restore, replace, rehabilitate, or 
    acquire the equivalent of the injured natural resources and services. 
    Sums recovered in settlement of such claims, other than reimbursement 
    of trustee costs, may only be expended in accordance with a restoration 
    plan, which may be set forth in whole or in part in a consent decree or 
    other settlement agreement, which is made available for public review.
    
    
    Sec. 990.26  Emergency restoration.
    
        (a) Trustees may take emergency restoration action before

    prevent additional injury; and
        (3) The costs of the action are not unreasonable.
        (b) If response actions are still underway, trustees, through their 
    Regional Response Team member or designee, must coordinate with the On-
    Scene Coordinator (OSC) before taking any emergency restoration 
    actions. Any emergency restoration actions proposed by trustees should 
    not interfere with on-going response actions. Trustees must explain to 
    response agencies through the OSC prior to implementation of emergency 
    restoration actions their reasons for believing that proposed emergency 
    restoration actions will not interfere with on-going response actions.
        (c) Trustees must provide notice to identified responsible parties 
    of any emergency restoration actions and, to the extent time permits, 
    invite their participation in the conduct of those actions as provided 
    in Sec. 990.14(c) of this part.
        (d) Trustees must provide notice to the public, to the extent 
    practicable, of these planned emergency restoration actions. Trustees 
    must also provide public notice of the justification for, nature and 
    extent of, and results of emergency restoration actions within a 
    reasonable time frame after completion of such actions. The means by 
    which this notice is provided is left to the discretion of the trustee.
    
    
    Sec. 990.27  Use of assessment procedures.
    
        (a) Standards for assessment procedures. Any procedures used 
    pursuant to this part must comply with all of the following standards 
    if they are to be in accordance with this part:
        (1) The procedure must be capable of providing assessment 
    information of use in determining the type and scale of restoration 
    appropriate for a particular injury;
        (2) The additional cost of a more complex procedure must be 
    reasonably related to the expected increase in the quantity and/or 
    quality of relevant information provided by the more complex procedure; 
    and
        (3) The procedure must be reliable and valid for the particular 
    incident.
        (b) Assessment procedures available. (1) The range of assessment 
    procedures available to trustees includes, but is not limited to:
        (i) Procedures conducted in the field;

    identified in 43 CFR part 11, subpart D, and compensation formulas/
    schedules; and
        (iv) Literature-based procedures.
        (2) Trustees may use the assessment procedures in paragraph (b)(1) 
    of this section alone, or in any combination, provided that the 
    standards in paragraph (a) of this section are met, and there is no 
    double recovery.
        (c) Selecting assessment procedures. (1) When selecting assessment 
    procedures, trustees must consider, at a minimum:
        (i) The range of procedures available under paragraph (b) of this 
    section;
        (ii) The time and cost necessary to implement the procedures;
        (iii) The potential nature, degree, and spatial and temporal extent 
    of the injury;
        (iv) The potential restoration actions for the injury; and
        (v) The relevance and adequacy of information generated by the 
    procedures to meet information requirements of restoration planning.
        (2) If a range of assessment procedures providing the same type and 
    quality of information is available, the most cost-effective procedure 
    must be used.

    Subpart D--Preassessment Phase
    
    
    Sec. 990.40  Purpose.
    
        The purpose of this subpart is to provide a process by which 
    trustees determine if they have jurisdiction to pursue restoration 
    under OPA and, if so, whether it is appropriate to do so.
    
    
    Sec. 990.41  Determination of jurisdiction.
    
        (a) Determination of jurisdiction. Upon learning of an incident, 
    trustees must determine whether there is jurisdiction to pursue 
    restoration under OPA. To make this determination, trustees must decide 
    if:
        (1) An incident has occurred, as defined in Sec. 990.30 of this 
    part;
        (2) The incident is not:
        (i) Permitted under a permit issued under federal, state, or local 
    law; or
        (ii) From a public vessel; or
        (iii) From an onshore facility subject to the Trans-Alaska Pipeline 
    Authority Act, 43 U.S.C. 1651, et seq.; and
        (3) Natural resources under the trusteeship of the trustee may have 
    been, or may be, injured as a result of the incident.
        (b) Proceeding with preassessment. If the conditions listed in 
    paragraph (a) of this section are met, trustees may proceed under this 
    part. If one of the conditions is not met, trustees may not take 
    additional action under this part, except action to finalize this 
    determination. Trustees may recover all reasonable assessment costs 
    incurred up to this point provided that conditions in paragraphs (a)(1) 
    and (a)(2) of this section were met and actions were taken with the 
    reasonable belief that natural resources or services under their 
    trusteeship might have been injured as a result of the incident.
    
    
    Sec. 990.42  Determination to conduct restoration planning.
    
        (a) Determination on restoration planning. If trustees determine 
    that there is jurisdiction to pursue restoration under OPA, trustees 
    must determine whether:
        (1) Injuries have resulted, or are likely to result, from the 
    incident;
        (2) Response actions have not adequately addressed, or are not 
    expected to address, the injuries resulting from the incident; and
        (3) Feasible primary and/or compensatory restoration actions exist 
    to address the potential injuries.
        (b) Proceeding with preassessment. If the conditions listed in 
    paragraph (a) of this section are met, trustees may proceed under 
    Sec. 990.44 of this part. If one of these conditions is not met, 
    trustees may not take additional action under this part, except action 
    to finalize this determination. However, trustees may recover all 
    reasonable assessment costs incurred up to this point.
    
    
    Sec. 990.43  Data collection.
    
        Trustees may conduct data collection and analyses that are 
    reasonably related to Preassessment Phase activities. Data collection 
    and analysis during the Preassessment Phase must be coordinated with 
    response actions such that collection and analysis does not interfere 
    with response actions. Trustees may collect and analyze the following 
    types of data during the Preassessment Phase:
        (a) Data reasonably expected to be necessary to make a 
    determination of jurisdiction under Sec. 990.41 of this part, or a 
    determination to conduct restoration planning under Sec. 990.42 of this 
    part;
        (b) Ephemeral data; and
        (c) Information needed to design or implement anticipated 
    assessment procedures under subpart E of this part.
    
    
    Sec. 990.44  Notice of Intent to Conduct Restoration Planning.
    
        (a) General. If trustees determine that all the conditions under 
    Sec. 990.42(a) of this part are met and trustees decide to proceed with 
    the natural resource damage assessment, they must prepare a Notice of 
    Intent to Conduct Restoration Planning.
        (b) Contents of the notice. The Notice of Intent to Conduct 
    Restoration Planning must include a discussion of the trustees' 
    analyses under Secs. 990.41 and 990.42 of this part. Depending on 
    information available at this point, the notice may include the 
    trustees' 
    
    [[Page 506]]
    proposed strategy to assess injury and determine the type and scale of 
    restoration. The contents of a notice may vary, but will typically 
    discuss:
        (1) The facts of the incident;
        (2) Trustee authority to proceed with the assessment;
        (3) Natural resources and services that are, or are likely to be, 
    injured as a result of the incident;
        (4) Potential restoration actions relevant to the expected 
    injuries; and
        (5) If determined at the time, potential assessment procedures to 
    evaluate the injuries and define the appropriate type and scale of 
    restoration for the injured natural resources and services.
        (c) Public availability of the notice. Trustees must make a copy of 
    the Notice of Intent to Conduct Restoration Planning publicly 
    available. The means by which the notice is made publicly available and 
    whether public comments are solicited on the notice will depend on the 
    nature and extent of the incident and various information requirements, 
    and is left to the discretion of the trustees.
        (d) Delivery of the notice to the responsible parties. Trustees 
    must send a copy of the notice to the responsible parties, to the 
    extent known, in such a way as will establish the date of receipt, and 
    invite responsible parties' participation in the conduct of restoration 
    planning. Consistent with Sec. 990.14(c) of this part, the 
    determination of the timing, nature, and extent of responsible party 
    participation will be determined by the trustees on an incident-
    specific basis.
    
    
    Sec. 990.45  Administrative record.
    
        (a) If trustees decide to proceed with restoration planning, they 
    must open a publicly available administrative record to document the 
    basis for their decisions pertaining to restoration. The administrative 
    record should be opened concurrently with the publication of the Notice 
    of Intent to Conduct Restoration Planning. Depending on the nature and 
    extent of the incident and assessment, the administrative record should 
    include documents relied upon during the assessment, such as:
        (1) Any notice, draft and final restoration plans, and public 
    comments;
        (2) Any relevant data, investigation reports, scientific studies, 
    work plans, quality assurance plans, and literature; and
        (3) Any agreements, not otherwise privileged, among the 
    participating trustees or with the responsible parties.
        (b) Federal trustees should maintain the administrative record in a 
    manner consistent with the Administrative Procedure Act, 5 U.S.C. 551-

    Sec. 990.50  Purpose.
    
        The purpose of this subpart is to provide a process by which 
    trustees evaluate and quantify potential injuries (injury assessment), 
    and use that information to determine the need for and scale of 
    restoration actions (restoration selection).
    
    
    Sec. 990.51  Injury assessment--injury determination.
    
        (a) General. After issuing a Notice of Intent to Conduct 
    Restoration Planning under Sec. 990.44 of this part, trustees must 
    determine if injuries to natural resources and/or services have 
    resulted from the incident.
        (b) Determining injury. To make the determination of injury, 
    trustees must evaluate if:
        (1) The definition of injury has been met, as defined in 
    Sec. 990.30 of this part; and
        (2)(i) An injured natural resource has been exposed to the 
    discharged oil, and a pathway can be established from the discharge to 
    the exposed natural resource; or
        (ii) An injury to a natural resource or impairment of a natural 
    resource service has occurred as a result of response actions or a 
    substantial threat of a discharge of oil.
        (c) Identifying injury. Trustees must determine whether an injury 
    has occurred and, if so, identify the nature of the injury. Potential 
    categories of injury include, but are not limited to, adverse changes 
    in: survival, growth, and reproduction; health, physiology and 
    biological condition; behavior; community composition; ecological 
    processes and functions; physical and chemical habitat quality or 
    structure; and public services.
        (d) Establishing exposure and pathway. Except for injuries 
    resulting from response actions or incidents involving a substantial 
    threat of a discharge of oil, trustees must establish whether natural 
    resources were exposed, either directly or indirectly, to the 
    discharged oil from the incident, and estimate the amount or 
    concentration and spatial and temporal extent of the exposure. Trustees 
    must also determine whether there is a pathway linking the incident to 
    the injuries. Pathways may include, but are not limited to, the 
    sequence of events by which the discharged oil was transported from the 
    incident and either came into direct physical contact with a natural 
    resource, or caused an indirect injury.
        (e) Injuries resulting from response actions or incidents involving 
    a substantial threat of a discharge. For injuries resulting from 
    response actions or incidents involving a substantial threat of a 
    discharge of oil, trustees must determine whether an injury or an 
    impairment of a natural resource service has occurred as a result of 
    the incident.
        (f) Selection of injuries to include in the assessment. When 
    selecting potential injuries to assess, trustees should consider 
    factors such as:
        (1) The natural resources and services of concern;
        (2) The procedures available to evaluate and quantify injury, and 
    associated time and cost requirements;
        (3) The evidence indicating exposure;
        (4) The pathway from the incident to the natural resource and/or 
    service of concern;
        (5) The adverse change or impairment that constitutes injury;
        (6) The evidence indicating injury;
        (7) The mechanism by which injury occurred;
        (8) The potential degree, and spatial and temporal extent of the 
    injury;
        (9) The potential natural recovery period; and
        (10) The kinds of primary and/or compensatory restoration actions 
    that are feasible.
    
    
    Sec. 990.52  Injury assessment--quantification.
    
        (a) General. In addition to determining whether injuries have 
    resulted from the incident, trustees must quantify the degree, and 
    spatial and temporal extent of such injuries relative to baseline.
        (b) Quantification approaches. Trustees may quantify injuries in 
    terms of:
        (1) The degree, and spatial and temporal extent of the injury to a 
    natural resource;
        (2) The degree, and spatial and temporal extent of injury to a 
    natural resource, with subsequent translation of that adverse change to 
    a reduction in services provided by the natural resource; or
        (3) The amount of services lost as a result of the incident.
        (c) Natural recovery. To quantify injury, trustees must estimate, 
    quantitatively or qualitatively, the time for natural recovery without 
    restoration, but including any response actions. The analysis of 
    natural recovery may consider such factors as:
        (1) The nature, degree, and spatial and temporal extent of injury;
        (2) The sensitivity and vulnerability of the injured natural 
    resource and/or service; 
    
    [[Page 507]]
    
        (3) The reproductive and recruitment potential;
        (4) The resistance and resilience (stability) of the affected 
    environment;
        (5) The natural variability; and
        (6) The physical/chemical processes of the affected environment.
    
    
    Sec. 990.53  Restoration selection--developing restoration 
    alternatives.
    
        (a) General. (1) If the information on injury determination and 
    quantification under Secs. 990.51 and 990.52 of this part and its 
    relevance to restoration justify restoration, trustees may proceed with 
    the Restoration Planning Phase. Otherwise, trustees may not take 
    additional action under this part. However, trustees may recover all 
    reasonable assessment costs incurred up to this point.
        (2) Trustees must consider a reasonable range of restoration 
    alternatives before selecting their preferred alternative(s). Each 
    restoration alternative is comprised of primary and/or compensatory 
    restoration components that address one or more specific injury(ies) 
    associated with the incident. Each alternative must be designed so 
    that, as a package of one or more actions, the alternative would make 
    the environment and public whole. Only those alternatives considered 
    technically feasible and in accordance with applicable laws, 
    regulations, or permits may be considered further under this part.
        (b) Primary restoration. (1) General. For each alternative, 
    trustees must consider primary restoration actions, including a natural 
    recovery alternative.
        (2) Natural recovery. Trustees must consider a natural recovery 
    alternative in which no human intervention would be taken to directly 
    restore injured natural resources and services to baseline.
        (3) Active primary restoration actions. Trustees must consider an 
    alternative comprised of actions to directly restore the natural 
    resources and services to baseline on an accelerated time frame. When 
    identifying such active primary restoration actions, trustees may 
    consider actions that:
        (i) Remove conditions that would prevent or limit the effectiveness 
    of any restoration action (e.g., residual sources of contamination);
        (ii) May be necessary to return the physical, chemical, and/or 
    biological conditions necessary to allow recovery or restoration of the 
    injured natural resources (e.g., replacing substrate or vegetation, or 
    modifying hydrologic conditions); or
        (iii) Return key natural resources and services, and would be an 
    effective approach to achieving or accelerating a return to baseline 
    (e.g., replacing essential species, habitats, or public services that 
    would facilitate the replacement of other, dependent natural resource 
    or service components).
        (c) Compensatory restoration. (1) General. For each alternative, 
    trustees must also consider compensatory restoration actions to 
    compensate for the interim loss of natural resources and services 
    pending recovery.
        (2) Compensatory restoration actions. To the extent practicable, 
    when evaluating compensatory restoration actions, trustees must 
    consider compensatory restoration actions that provide services of the 
    same type and quality, and of comparable value as those injured. If, in 
    the judgment of the trustees, compensatory actions of the same type and 
    quality and comparable value cannot provide a reasonable range of 
    alternatives, trustees should identify actions that provide natural 
    resources and services of comparable type and quality as those provided 
    by the injured natural resources. Where the injured and replacement 
    natural resources and services are not of comparable value, the scaling 
    process will involve valuation of lost and replacement services.
        (d) Scaling restoration actions. (1) General. After trustees have 
    identified the types of restoration actions that will be considered, 
    they must determine the scale of those actions that will make the 
    environment and public whole. For primary restoration actions, scaling 
    generally applies to actions involving replacement and/or acquisition 
    of equivalent of natural resources and/or services.
        (2) Resource-to-resource and service-to-service scaling approaches. 
    When determining the scale of restoration actions that provide natural 
    resources and/or services of the same type and quality, and of 
    comparable value as those lost, trustees must consider the use of a 
    resource-to-resource or service-to-service scaling approach. Under this 
    approach, trustees determine the scale of restoration actions that will 
    provide natural resources and/or services equal in quantity to those 
    lost.
        (3) Valuation scaling approach. (i) Where trustees have determined 
    that neither resource-to-resource nor service-to-service scaling is 
    appropriate, trustees may use the valuation scaling approach. Under the 
    valuation scaling approach, trustees determine the amount of natural 
    resources and/or services that must be provided to produce the same 
    value lost to the public. Trustees must explicitly measure the value of 
    injured natural resources and/or services, and then determine the scale 
    of the restoration action necessary to produce natural resources and/or 
    services of equivalent value to the public.
        (ii) If, in the judgment of the trustees, valuation of the lost 
    services is practicable, but valuation of the replacement natural 
    resources and/or services cannot be performed within a reasonable time 
    frame or at a reasonable cost, as determined by Sec. 990.27(a)(2) of 
    this part, trustees may estimate the dollar value of the lost services 
    and select the scale of the restoration action that has a cost 
    equivalent to the lost value. The responsible parties may request that 
    trustees value the natural resources and services provided by the 
    restoration action following the process described in Sec. 990.14(c) of 
    this part.
        (4) Discounting and uncertainty. When scaling a restoration action, 
    trustees must evaluate the uncertainties associated with the projected 
    consequences of the restoration action, and must discount all service 
    quantities and/or values to the date the demand is presented to the 
    responsible parties. Where feasible, trustees should use risk-adjusted 
    measures of losses due to injury and of gains from the restoration 
    action, in conjunction with a riskless discount rate representing the 
    consumer rate of time preference. If the streams of losses and gains 
    cannot be adequately adjusted for risks, then trustees may use a 
    discount rate that incorporates a suitable risk adjustment to the 
    riskless rate.
    
    
    Sec. 990.54  Restoration selection--evaluation of alternatives.
    
        (a) Evaluation standards. Once trustees have developed a reasonable 
    range of restoration alternatives under Sec. 990.53 of this part, they 
    must evaluate the proposed alternatives based on, at a minimum:
        (1) The cost to carry out the alternative;
        (2) The extent to which each alternative is expected to meet the 
    trustees' goals and objectives in returning the injured natural 
    resources and services to baseline and/or compensating for interim 
    losses;
        (3) The likelihood of success of each alternative;
        (4) The extent to which each alternative will prevent future injury 
    as a result of the incident, and avoid collateral injury as a result of 
    implementing the alternative;
        (5) The extent to which each alternative benefits more than one 
    natural resource and/or service; and
        (6) The effect of each alternative on public health and safety. 
        
    [[Page 508]]
    
        (b) Preferred restoration alternatives. Based on an evaluation of 
    the factors under paragraph (a) of this section, trustees must select a 
    preferred restoration alternative(s). If the trustees conclude that two 
    or more alternatives are equally preferable based on these factors, the 
    trustees must select the most cost-effective alternative.
        (c) Pilot projects. Where additional information is needed to 
    identify and evaluate the feasibility and likelihood of success of 
    restoration alternatives, trustees may implement restoration pilot 
    projects. Pilot projects should only be undertaken when, in the 
    judgment of the trustees, these projects are likely to provide the 
    information, described in paragraph (a) of this section, at a 
    reasonable cost and in a reasonable time frame.
    
    
    Sec. 990.55  Restoration selection--developing restoration plans.
    
        (a) General. OPA requires that damages be based upon a plan 
    developed with opportunity for public review and comment. To meet this 
    requirement, trustees must, at a minimum, develop a Draft and Final 
    Restoration Plan, with an opportunity for public review of and comment 
    on the draft plan.
        (b) Draft Restoration Plan. (1) The Draft Restoration Plan should 
    include:
        (i) A summary of injury assessment procedures used;
        (ii) A description of the nature, degree, and spatial and temporal 
    extent of injuries resulting from the incident;
        (iii) The goals and objectives of restoration;
        (iv) The range of restoration alternatives considered, and a 
    discussion of how such alternatives were developed under Sec. 990.53 of 
    this part, and evaluated under Sec. 990.54 of this part;
        (v) Identification of the trustees' tentative preferred 
    alternative(s);
        (vi) A description of past and proposed involvement of the 
    responsible parties in the assessment; and
        (vii) A description of monitoring for documenting restoration 
    effectiveness, including performance criteria that will be used to 
    determine the success of restoration or need for interim corrective 
    action.
        (2) When developing the Draft Restoration Plan, trustees must 
    establish restoration objectives that are specific to the injuries. 
    These objectives should clearly specify the desired outcome, and the 
    performance criteria by which successful restoration will be judged. 
    Performance criteria may include structural, functional, temporal, and/
    or other demonstrable factors. Trustees must, at a minimum, determine 
    what criteria will:
        (i) Constitute success, such that responsible parties are relieved 
    of responsibility for further restoration actions; or
        (ii) Necessitate corrective actions in order to comply with the 
    terms of a restoration plan or settlement agreement.
        (3) The monitoring component to the Draft Restoration Plan should 
    address such factors as duration and frequency of monitoring needed to 
    gauge progress and success, level of sampling needed to detect success 
    or the need for corrective action, and whether monitoring of a 
    reference or control site is needed to determine progress and success. 
    Reasonable monitoring and oversight costs cover those activities 
    necessary to gauge the progress, performance, and success of the 
    restoration actions developed under the plan.
        (c) Public review and comment. The nature of public review and 
    comment on the Draft and Final Restoration Plans will depend on the 
    nature of the incident and any applicable federal trustee NEPA 
    requirements, as described in Secs. 990.14(d) and 990.23 of this part.
        (d) Final Restoration Plan. Trustees must develop a Final 
    Restoration Plan that includes the information specified in paragraph 
    (a) of this section, responses to public comments, if applicable, and 
    an indication of any changes made to the Draft Restoration Plan.
    
    
    Sec. 990.56  Restoration selection--use of a Regional Restoration Plan 
    or existing restoration project.
    
        (a) General. Trustees may consider using a Regional Restoration 
    Plan or existing restoration project where such a plan or project is 
    determined to be the preferred alternative among a range of feasible 
    restoration alternatives for an incident, as determined under 
    Sec. 990.54 of this part. Such plans or projects must be capable of 
    fulfilling OPA's intent for the trustees to restore, rehabilitate, 
    replace, or acquire the equivalent of the injured natural resources and 
    services and compensate for interim losses.
        (b) Existing plans or projects--(1) Considerations. Trustees may 
    select a component of a Regional Restoration Plan or an existing 
    restoration project as the preferred alternative, provided that the 
    plan or project:
        (i) Was developed with public review and comment or is subject to 
    public review and comment under this part;
        (ii) Will adequately compensate the environment and public for 
    injuries resulting from the incident;
        (iii) Addresses, and is currently relevant to, the same or 
    comparable natural resources and services as those identified as having 
    been injured; and
        (iv) Allows for reasonable scaling relative to the incident.
        (2) Demand. (i) If the conditions of paragraph (b)(1) of this 
    section are met, the trustees must invite the responsible parties to 
    implement that component of the Regional Restoration Plan or existing 
    restoration project, or advance to the trustees the trustees' 
    reasonable estimate of the cost of implementing that component of the 
    Regional Restoration Plan or existing restoration project.
        (ii) If the conditions of paragraph (b)(1) of this section are met, 
    but the trustees determine that the scale of the existing plan or 
    project is greater than the scale of compensation required by the 
    incident, trustees may only request funding from the responsible 
    parties equivalent to the scale of the restoration determined to be 
    appropriate for the incident of concern. Trustees may pool such partial 
    recoveries until adequate funding is available to successfully 
    implement the existing plan or project.
        (3) Notice of Intent To Use a Regional Restoration Plan or Existing 
    Restoration Project. If trustees intend to use an appropriate component 
    of a Regional Restoration Plan or existing restoration project, they 
    must prepare a Notice of Intent to Use a Regional Restoration Plan or 
    Existing Restoration Project. Trustees must make a copy of the notice 
    publicly available. The notice must include, at a minimum:
        (i) A description of the nature, degree, and spatial and temporal 
    extent of injuries; and
        (ii) A description of the relevant component of the Regional 
    Restoration Plan or existing restoration project; and
        (iii) An explanation of how the conditions set forth in paragraph 
    (b)(1) of this section are met.
    
    Subpart F--Restoration Implementation Phase
    
    
    Sec. 990.60  Purpose.
    
        The purpose of this subpart is to provide a process for 
    implementing restoration.
    
    
    Sec. 990.61   Administrative record.
    
        (a) Closing the administrative record for restoration planning. 
    Within a reasonable time after the trustees have completed restoration 
    planning, as provided in Secs. 990.55 and 990.56 of this part, they 
    must close the administrative record. Trustees may not add 
    
    [[Page 509]]
    documents to the administrative record once it is closed, except where 
    such documents:
         (1) Are offered by interested parties that did not receive actual 
    or constructive notice of the Draft Restoration Plan and the 
    opportunity to comment on the plan;
        (2) Do not duplicate information already contained in the 
    administrative record; and
        (3) Raise significant issues regarding the Final Restoration Plan.
        (b) Opening an administrative record for restoration 
    implementation. Trustees may open an administrative record for 
    implementation of restoration, as provided in Sec. 990.45 of this part. 
    The costs associated with the administrative record are part of the 
    costs of restoration. Ordinarily, the administrative record for 
    implementation of restoration should document, at a minimum, all 
    Restoration Implementation Phase decisions, actions, and expenditures, 
    including any modifications made to the Final Restoration Plan.
    
    
    Sec. 990.62   Presenting a demand.
    
        (a) General. After closing the administrative record for 
    restoration planning, trustees must present a written demand to the 
    responsible parties. Delivery of the demand should be made in a manner 
    that establishes the date of receipt by the responsible parties.
        (b) When a Final Restoration Plan has been developed. Except as 
    provided in paragraph (c) of this section and in Sec. 990.14(c) of this 
    part, the demand must invite the responsible parties to either:
        (1) Implement the Final Restoration Plan subject to trustee 
    oversight and reimburse the trustees for their assessment and oversight 
    costs; or
        (2) Advance to the trustees a specified sum representing trustee 
    assessment costs and all trustee costs associated with implementing the 
    Final Restoration Plan, discounted as provided in Sec. 990.63(a) of 
    this part.
        (c) Regional Restoration Plan or existing restoration project. When 
    the trustees use a Regional Restoration Plan or an existing restoration 
    project under Sec. 990.56 of this part, the demand will invite the 
    responsible parties to implement a component of a Regional Restoration 
    Plan or existing restoration project, or advance the trustees' estimate 
    of damages based on the scale of the restoration determined to be 
    appropriate for the incident of concern, which may be the entire 
    project or a portion thereof.
        (d) Response to demand. The responsible parties must respond within 
    ninety (90) calendar days in writing by paying or providing binding 
    assurance they will reimburse trustees' assessment costs and implement 
    the plan or pay assessment costs and the trustees' estimate of the 
    costs of implementation.
        (e) Additional contents of demand. The demand must also include:
        (1) Identification of the incident from which the claim arises;
        (2) Identification of the trustee(s) asserting the claim and a 
    statement of the statutory basis for trusteeship;
        (3) A brief description of the injuries for which the claim is 
    being brought;
        (4) An index to the administrative record;
        (5) The Final Restoration Plan or Notice of Intent to Use a 
    Regional Restoration Plan or Existing Restoration Project; and
        (6) A request for reimbursement of:
        (i) Reasonable assessment costs, as defined in Sec. 990.30 of this 
    part and discounted as provided in Sec. 990.63(b) of this part;
        (ii) The cost, if any, of conducting emergency restoration under 
    Sec. 990.26 of this part, discounted as provided in Sec. 990.63(b) of 
    this part; and
        (iii) Interest on the amounts recoverable, as provided in section 
    1005 of OPA (33 U.S.C. 2705), which allows for prejudgment and post-
    judgment interest to be paid at a commercial paper rate, starting from 
    thirty (30) calendar days from the date a demand is presented until the 
    date the claim is paid.
    
    
    Sec. 990.63   Discounting and compounding.
    
        (a) Estimated future restoration costs. When determining estimated 
    future costs of implementing a Final Restoration Plan, trustees must 
    discount such future costs back to the date the demand is presented. 
    Trustees may use a discount rate that represents the yield on 
    recoveries available to trustees. The price indices used to project 
    future inflation should reflect the major components of the restoration 
    costs.
        (b) Past assessment and emergency restoration costs. When 
    calculating the present value of assessment and emergency restoration 
    costs already incurred, trustees must compound the costs forward to the 
    date the demand is presented. To perform the compounding, trustees may 
    use the actual U.S. Treasury borrowing rate on marketable securities of 
    comparable maturity to the period of analysis. For costs incurred by 
    state or tribal trustees, trustees may compound using parallel state or 
    tribal borrowing rates.
        (c) Trustees are referred to Appendices B and C of OMB Circular A-
    94 for information about U.S. Treasury rates of various maturities and 
    guidance in calculation procedures. Copies of Appendix C, which is 
    regularly updated, and of the Circular are available from the OMB 
    Publications Office (202-395-7332).
    
    
    Sec. 990.64   Unsatisfied demands.
    
        (a) If the responsible parties do not agree to the demand within 
    ninety (90) calendar days after trustees present the demand, the 
    trustees may either file a judicial action for damages or seek an 
    appropriation from the Oil Spill Liability Trust Fund, as provided in 
    section 1012(a)(2) of OPA (33 U.S.C. 2712(a)(2)).
        (b) Judicial actions and claims must be filed within three (3) 
    years after the Final Restoration Plan or Notice of Intent to Use a 
    Regional Restoration Plan or Existing Restoration Project is made 
    publicly available, in accordance with 33 U.S.C. 2717(f)(1)(B) and 
    2712(h)(2).
    
    
    Sec. 990.65   Opening an account for recovered damages.
    
        (a) General. Sums recovered by trustees in satisfaction of a 
    natural resource damage claim must be placed in a revolving trust 
    account. Sums recovered for past assessment costs and emergency 
    restoration costs may be used to reimburse the trustees. All other sums 
    must be used to implement the Final Restoration Plan or all or an 
    appropriate component of a Regional Restoration Plan or an existing 
    restoration project.
        (b) Joint trustee recoveries. (1) General. Trustees may establish a 
    joint account for damages recovered pursuant to joint assessment 
    activities, such as an account under the registry of the applicable 
    federal court.
        (2) Management. Trustees may develop enforceable agreements to 
    govern management of joint accounts, including agreed-upon criteria and 
    procedures, and personnel for authorizing expenditures out of such 
    joint accounts.
