    Natural Resource Damage Assessments
    
    AGENCY: Department of the Interior.
    
    ACTION: Advance notice of proposed rulemaking.
    
    -----------------------------------------------------------------------
    
    SUMMARY: The Department of the Interior is initiating a biennial review 
    of the regulations for assessing natural resource damages resulting 
    from a discharge of oil into navigable waters under the Clean Water Act 
    or a release of a hazardous substance under the Comprehensive 
    Environmental Response, Compensation, and Liability Act. The 
    regulations provide procedures that Federal, State, and Indian tribe 
    natural resource trustees may use to obtain compensation from 
    potentially responsible parties for injuries to natural resources. The 
    regulations provide an administrative process for conducting 
    assessments as well as two types of technical procedures for the actual 
    determination of injuries and damages. ``Type A'' procedures are 
    standard procedures for simplified assessments requiring minimal field 
    observation in cases of minor discharges or releases in certain 
    environments. ``Type B'' procedures are site-specific procedures for 
    detailed assessments in other cases. This advance notice solicits 
    comment on how the administrative process and all but one of the type B 
    procedures should be revised.
    
    DATES: Comments will be accepted through January 17, 1995.

    I. Statutory Provisions
    
        This notice announces the commencement of a review of regulations 
    for assessing natural resource damages under the Comprehensive 
    Environmental Response, Compensation, and Liability Act, as amended (42 
    U.S.C. 9601 et seq.) (CERCLA) and the Clean Water Act, as amended (33 
    U.S.C. 1251 et seq.) (CWA). Under CERCLA, certain categories of 
    potentially responsible parties (PRPs) are liable for natural resource 
    damages resulting from a release of a hazardous substance. CERCLA sec. 
    107(a). Natural resource damages are monetary compensation for injury 
    to, destruction of, or loss of natural resources. CERCLA sec. 
    107(a)(4)(C). CWA creates similar liability for natural resource 
    damages resulting from discharges of oil into navigable waters. CWA 
    sec. 311(f).
        Only designated natural resource trustees may recover natural 
    resource damages. CWA recognizes the authority of Federal and State 
    officials to serve as natural resource trustees. CERCLA recognizes the 
    authority of Federal and State officials as well as Indian tribes to 
    act as natural resource trustees. CERCLA defines ``State'' to include:
    
        The District of Columbia, the Commonwealth of Puerto Rico, Guam, 
    American Samoa, the United States Virgin Islands, the Commonwealth 
    of the Northern Marianas, and any other territory or possession over 
    which the United States has jurisdiction. CERCLA sec. 101(27).
    
        Damages may be recovered for those natural resource injuries that 
    are not fully remedied by response actions as well as public economic 
    values lost from the date of the discharge or release until the 
    resources have fully recovered. All sums recovered in compensation for 
    natural resource injuries must be used to restore, rehabilitate, 
    replace, or acquire the equivalent of the injured natural resources. 
    CERCLA sec. 107(f)(1). Trustee officials may also recover the 
    reasonable costs of assessing natural resource damages.
        CERCLA requires the promulgation of regulations for the assessment 
    of natural resource damages resulting either from a discharge of oil 
    into navigable waters under CWA or from a release of a hazardous 
    substance under CERCLA. CERCLA sec. 301(c)(1). These regulations are to 
    identify the ``best available'' procedures for assessing natural 
    resource damages. CERCLA sec. 301(c)(2). CERCLA requires that the 
    natural resource damage assessment regulations include two types of 
    assessment procedures. ``Type A'' procedures are ``standard procedures 
    for simplified assessments requiring minimal field observation.'' 
    CERCLA sec. 301(c)(2)(A). ``Type B'' procedures are ``alternative 
    protocols for conducting assessments in individual cases.'' CERCLA sec. 
    301(c)(2)(B). Assessments performed by Federal and State trustee 
    officials in accordance with the natural resource damage assessment 
    regulations receive a rebuttable presumption in court. CERCLA sec. 
    107(f)(2)(C). The promulgation of these regulations was delegated to 
    the Department of the Interior (the Department). E.O. 12316, as amended 
    by E.O. 12580.
        The natural resource damage provisions of CWA were amended by the 
    Oil Pollution Act (33 U.S.C. 2701 et seq.) (OPA). The authority to sue 
    for natural resource damages resulting from discharges of oil into 
    navigable waters was extended to not only Federal and State natural 
    resource trustees but also Indian tribe and foreign natural resource 
    trustees. OPA also authorized the National Oceanic and Atmospheric 
    Administration (NOAA) to develop new natural resource damage assessment 
    regulations for discharges of oil into navigable waters. The Department 
    is coordinating its rulemakings with NOAA to ensure, to the maximum 
    extent appropriate, that consistent processes are established for 
    assessing natural resource damages under CERCLA and OPA.
        OPA provides that any rule in effect under a law replaced by OPA 
    will continue in effect until superseded. OPA sec. 6001(b). In 
    particular, Senate committee report language makes it clear that 
    ``[t]he existing Interior Department rules * * * may be used with a 
    rebuttable presumption in the interim'' until NOAA promulgates new 
    regulations. S. Rep. No. 101-94, 101st Cong., 1st Sess. 15 (1990). 
    Therefore, until NOAA promulgates its regulations, the Department's 
    regulations may be used to obtain a rebuttable presumption for natural 
    resource damage assessments under OPA.
        The Department's natural resource damage assessment regulations 
    must be reviewed, and revised as appropriate, every two years. CERCLA 
    sec. 301(c)(3). The regulations provide an administrative process for 
    conducting assessments as well as technical type A and type B 
    procedures for the actual determination of injuries and damages. The 
    purpose of this advance notice is to announce the beginning of the 
    biennial review of the administrative process and all but one of the 
    type B procedures.
    
    II. Overview of the Department's Natural Resource Damage Assessment 
    Regulations
    
        The Department has published various final rules for the assessment 
    of natural resource damages: 51 FR 27674 (Aug. 1, 1986); 52 FR 9042 
    (March 20, 1987); 53 FR 5166 (Feb. 22, 1988); and 53 FR 9769 (March 25, 
    1988). These rulemakings are codified in the Code of Federal 
    Regulations at 43 CFR part 11. The Department also recently published a 
    final rule revising the administrative process and the type B 
    procedures that has not yet been codified in the Code of Federal 
    Regulations. 59 FR 14261 (March 25, 1994).
        The Department's natural resource damage assessment regulations 
    provide an administrative process for conducting assessments. The 
    administrative process consists of four phases: The Preassessment 
    Phase, the Assessment Plan Phase, the Assessment Phase, and the Post-
    Assessment Phase. The regulations also provide technical type A and 
    type B procedures to be used during the Assessment Phase for the actual 
    determination of injuries and damages.
        During this biennial review, the Department intends to examine all 
    aspects of the Preassessment Phase, Assessment Plan Phase, and Post-
    Assessment Phase, as well as all but one of the type B procedures 
    available for use during the Assessment Phase. The Department is 
    providing the following brief summary of its existing regulations to 
    assist commenters. Commenters should consult 43 CFR part 11 and 59 FR 
    14261 to obtain more detailed information about the administrative 
    process and type B procedures.
    
    A. Preassessment Phase
    
        The Preassessment Phase covers the activities that precede the 
    actual assessment. Upon detecting or receiving notification of a 
    discharge or release, trustee officials decide whether further 
    assessment actions are warranted. The Department's regulations provide 
    a number of criteria to assist trustee officials in making this 
    decision. The trustee officials' decision is documented in the 
    Preassessment Screen Determination. For more information on the 
    Preassessment Phase, see subpart B of 43 CFR part 11, as amended by 59 
    FR 14281.
    
    B. Assessment Plan Phase
    
        If trustee officials decide during the Preassessment Phase that the 
    criteria for continuing an assessment have been met, they then enter 
    the Assessment Plan Phase. The Assessment Plan Phase includes various 
    notification and coordination activities. The Department's regulations 
    provide guidance on coordination among trustee officials, including 
    selection of a ``lead authorized official'' to act as an administrative 
    point of contact. Trustee officials are also required to notify the 
    PRPs of their intent to perform an assessment.
        During the Assessment Plan Phase, trustee officials also prepare a 
    written Assessment Plan describing the procedures, type A, type B, or 
    both, that will be used to determine injury and damages. The Assessment 
    Plan is designed to focus and organize the assessment, which helps 
    ensure that only reasonable assessment costs are incurred. The 
    Assessment Plan is subject to public review and comment. For more 
    information on the Assessment Plan Phase, see subpart C of 43 CFR part 
    11, as amended by 59 FR 14281-83.
    
    C. Assessment Phase
    
        During the Assessment Phase, the work described in the Assessment 
    Plan is conducted. The work consists of three steps: Injury 
    Determination; Quantification; and Damage Determination. In Injury 
    Determination, trustee officials determine whether any natural 
    resources have been injured and whether there is a pathway of exposure 
    between the site of the discharge or release and the injured resources. 
    If trustee officials determine that resources have been injured and 
    that a pathway of exposure exists, they proceed to the Quantification 
    step.
        During Quantification, trustee officials quantify the extent of the 
    resource injuries by measuring the reduction from baseline conditions. 
    ``Baseline'' conditions are the conditions that would have existed had 
    the discharge or release not occurred. Resources perform functions for 
    humans and for other resources, such as provision of a food source, 
    flood control, or provision of recreational opportunities. These 
    functions are known as ``services.'' Reductions from baseline 
    conditions can be measured by evaluating the change in the level of 
    services provided by the injured resources.
        Finally, in Damage Determination, trustee officials calculate the 
    monetary compensation to be sought as damages for the quantified 
    natural resource injuries. The basic measure of damages is the cost of 
    restoring, rehabilitating, replacing, and/or acquiring the equivalent 
    of the injured resources. The Department's regulations also allow for 
    an additional component of damages. Trustee officials have the 
    discretion to assess damages for the economic value of the services 
    lost by the public from the date of the discharge or release until 
    completion of restoration, rehabilitation, replacement, and/or 
    acquisition of equivalent resources.
        This value is known as ``compensable value.''
        When a type A procedure is utilized, trustee officials perform 
    Injury Determination, Quantification, and Damage Determination through 
    the use of a standardized procedure involving minimal field work. The 
    Department is developing different type A procedures for different 
    environments in stages. Only one type A procedure has been included in 
    the regulations to date. That type A procedure incorporates a computer 
    model to perform Injury Determination, Quantification, and Damage 
    Determination for minor discharges or releases in coastal or marine 
    environments. The computer model is known as the Natural Resource 
    Damage Assessment Model for Coastal and Marine Environments (NRDAM/
    CME). For more information on use of a type A procedure during the 
    Assessment Phase, see subpart D of 43 CFR part 11. There are two 
    ongoing rulemakings concerning type A procedures. The Department is 
    revising the NRDAM/CME in compliance with a court order and the 
    statutory biennial review requirement. The Department is also 
    developing a new type A computer model for use in Great Lakes 
    environments. Therefore, the Department does not intend to address the 
    content of the type A procedures during this review.
        When a type A procedure is not applicable, trustee officials use 
    type B procedures instead of a type A procedure. In some cases, trustee 
    officials may also use type B procedures to supplement damages 
    calculated through use of an applicable type A procedure. When type B 
    procedures are utilized, trustee officials perform Injury 
    Determination, Quantification, and Damage Determination through the use 
    of site-specific studies. The Department's regulations divide natural 
    resources into five categories: surface water, ground water, air, 
    geologic, and biological resources. Specific definitions of injury are 
    provided for each of these categories. The regulations provide guidance 
    on the selection of testing and sampling methodologies to determine 
    whether an injury has occurred and whether a pathway of exposure 
    exists. The regulations also provide guidance on measuring the change 
    in baseline conditions during Quantification.
        During the Damage Determination step of an assessment incorporating 
    type B procedures, trustee officials identify and consider a reasonable 
    number of possible alternatives for restoring, rehabilitating, 
    replacing, and/or acquiring the equivalent of the injured resources. 
    Trustee officials select one of the possible alternatives based on 
    several factors. The trustee officials document their decisions in a 
    Restoration and Compensation Determination Plan, which is part of the 
    overall Assessment Plan and, thus, subject to public review and 
    comment.
        Once trustee officials have selected a restoration, rehabilitation, 
    replacement, and/or acquisition alternative, they select one or more of 
    the type B cost-estimating methodologies listed in the regulations. The 
    selected methodologies are used to estimate the cost of implementing 
    the restoration, rehabilitation, replacement, and/or acquisition 
    alternative. This estimated cost is the basic measure of damages. 
    Trustee officials also have the discretion to include compensable value 
    in their damage claim. Compensable value is calculated by applying one 
    or more of the type B economic valuation methodologies listed in the 
    regulations. For more information on use of type B procedures during 
    the Assessment Phase, see subpart E of 43 CFR part 11, as amended by 59 
    FR 14283-87.
    
    D. Post-Assessment Phase
    
        The Department's regulations cover the entire process that trustee 
    officials need to follow if they file a lawsuit and expect to obtain a 
    rebuttable presumption. Trustee officials have the authority to settle 
    their damage claims at any time during the administrative process. 
    However, if the trustee officials do not settle with the PRPs by the 
    end of the Assessment Phase, then trustee officials prepare a Report of 
    Assessment detailing the results of the Assessment Phase. Trustee 
    officials present the Report of Assessment to the PRPs along with a 
    demand for damages and assessment costs. If a PRP does not agree to pay 
    within 60 days, the trustee officials may file suit. Federal and State 
    trustee officials receive a rebuttable presumption of correctness for 
    assessments performed in accordance with the Preassessment Phase, 
    Assessment Plan Phase, Assessment Phase, and Post-Assessment Phase 
    procedures set forth in the regulations.
        Once damages have been awarded or settlement has been reached, 
    trustee officials establish an account for the recovered damages and 
    prepare a Restoration Plan for use of the funds. When type B procedures 
    are used, the post-assessment Restoration Plan is based on the 
    restoration, rehabilitation, replacement, and/or acquisition 
    alternative selected in the Restoration and Compensation Determination 
    Plan during the Assessment Phase. For more information on the Post-
    Assessment Phase, see subpart F of 43 CFR part 11, as amended by 59 FR 
    14287.
    
    III. Related Rulemakings
    
        There are several ongoing natural resource damage assessment 
    rulemakings other than this biennial review. State of Ohio v. United 
    States Department of the Interior (Ohio v. Interior) remanded portions 
    of the administrative process and the type B procedures. 880 F.2d 432 
    (D.C. Cir. 1989). On March 25, 1994, the Department published a final 
    rule that addressed all but one aspect of the remand. 59 FR 14261. The 
    March 25, 1994, final rule did not address the assessment of lost 
    nonuse values.
        There are two potential types of compensable values associated with 
    natural resource injuries: Lost use values and lost nonuse values. Use 
    values are derived through activities such as hiking or fishing. Nonuse 
    values are not dependent on use of a resource and include the value of 
    knowing that the resource exists and knowing that a resource will be 
    available for future generations. The only method available for the 
    express purpose of estimating lost nonuse values is the contingent 
    valuation methodology (CV). On May 4, 1994, the Department published a 
    notice of proposed rulemaking addressing CV as a type B procedure for 
    estimating lost nonuse values. 59 FR 23097. The comment period on the 
    notice closed on October 7, 1994. 59 FR 32175 (June 22, 1994). The 
    Department does not intend to address the assessment of lost nonuse 
    values during this review.
        State of Colorado v. United States Department of the Interior 
    remanded the type A procedure for coastal and marine environments. 880 
    F.2d 481 (D.C. Cir. 1989). The Department intends to publish a proposed 
    rule to revise the NRDAM/CME later this month.
        The Department has begun the development of an additional type A 
    procedure for use in Great Lakes environments. This type A procedure 
    uses a computer model known as the Natural Resource Damage Assessment 
    Model for Great Lakes Environments (NRDAM/GLE). The Department 
    published a proposed rule on August 8, 1994. 59 FR 40319. The 
    Department does not intend to address the content of the type A 
    procedures during this biennial review.
        Also, on January 7, 1994, NOAA published a proposed rule for 
    assessing natural resource damages resulting from oil discharges into 
    navigable waters under OPA. 59 FR 1062. The comment period on NOAA's 
    proposed rule closed on October 7, 1994. 59 FR 32148 (June 22, 1994).
    
    IV. Potential Topics for Review
    
        During this rulemaking, the Department will be considering ways of 
    revising the administrative process and the type B procedures to 
    reflect both experience to date in the use of the regulations as well 
    as scientific and technical advances. The Department solicits comment 
    on all aspects of the administrative process and the type B procedures, 
    other than the assessment of lost nonuse values. Based on the comments 
    received and its own analysis, the Department will develop a proposed 
    rule to revise the regulations.
        The Department has already received numerous comments on the 
    administrative process and type B procedures over the last few years. 
    One source of comments has been State briefings on use of the 
    regulations. The Department has provided these briefings to State 
    trustee officials at their request. Another source of comments has been 
    telephone calls from individuals requesting technical assistance in the 
    application of the regulations to particular cases. Also, in the course 
    of revising the regulations to comply with Ohio v. Interior, the 
    Department received numerous comments that were beyond the scope of 
    that rulemaking. As indicated during the Ohio v. Interior rulemaking, 
    the Department has included a discussion of all of those comments in 
    this notice. See 59 FR 14266.
        The following discussion is intended neither as an exhaustive 
    treatment of all possible topics for review nor as a definitive 
    indication of the Department's position. Instead, the discussion is 
    simply provided as an aid in generating further information and 
    analysis. Commenters are encouraged to provide comments not only on the 
    topics discussed in this notice but also on any other topics relating 
    to the administrative process or type B procedures that they deem 
    appropriate.
        During this biennial review, the Department will also examine the 
    relationship between its CERCLA damage assessment regulations and the 
    OPA damage assessment regulations being developed by NOAA. The 
    Department will consider ways of clarifying the applicability of its 
    regulations versus NOAA's regulations. In this regard, the Department 
    solicits comment on what provisions, if any, its regulations should 
    continue to make for assessing damages from oil discharges. The 
    Department will also coordinate with NOAA to ensure the greatest 
    consistency appropriate between the two sets of regulations. The 
    Department has noted in the following discussion certain areas where 
    NOAA has proposed an approach that differs from that currently taken in 
    the Department's regulations. The Department solicits comment on 
    whether the Department's regulations should be revised to follow the 
    approach proposed by NOAA in areas of difference.
    
    A. Administrative Process
    
    1. Streamlining
        One frequent comment has been that the Department's regulations are 
    ``too wordy'' and ``not in plain English.'' Many commenters have 
    indicated that the administrative process is too complicated and needs 
    to be streamlined. NOAA's proposed OPA rule provides for an ``Expedited 
    Damage Assessment'' based on ``limited, focused studies in order to 
    facilitate restoration as soon as possible.'' 59 FR 1177.
        Given the wide variety of activities involved in assessing damages, 
    the number of legal, scientific, and economic issues involved in damage 
    assessments, and the broad range of possible types of natural resource 
    damage cases, a certain level of intricacy is unavoidable in the 
    regulations. However, the administrative process and type B procedures 
    were designed to provide trustee officials with the flexibility to 
    tailor the scope and level of detail of an assessment to meet the needs 
    of the particular case. Trustee officials choose from a menu of 
    available type B procedures, using only those procedures and assessing 
    only those injuries and losses that they deem appropriate and adjusting 
    the level of documentation accordingly. The regulations allow both for 
    the performance of a limited number of short-term studies in a simple 
    case involving the release of a single substance affecting a single 
    resource, as well as the performance of numerous, long-term studies in 
    a complex case of a release of multiple substances affecting multiple 
    resources.
        Nevertheless, the Department aims to make the regulations as clear 
    and straightforward as possible. Therefore, the Department solicits 
    comment on specific aspects of the administrative process that 
    commenters consider unduly burdensome or complicated.
    2. Preassessment Phase
        Several commenters requested additional guidance on the conduct of 
    preassessment activities. NOAA has developed a draft guidance document 
    on preassessment activities under OPA. See 59 FR 1065.
        The Department's regulations already contain some guidance on 
    preassessment activities. See 43 CFR Secs. 11.20-11.25. The Department 
    notes that developing guidance requires balancing increased 
    predictability against reduced flexibility to respond to the unique 
    features of the broad range of potential natural resource damage cases. 
    Thus, there is a limit to the level of specificity that can be 
    appropriately provided in the regulations. With this in mind, the 
    Department solicits comment on specific aspects of the Preassessment 
    Phase that warrant additional guidance. The Department also solicits 
    comment on whether the guidance should be incorporated in the 
    regulations or in a separate guidance document.
        Some commenters questioned whether a preassessment screen should be 
    required when a type A procedure is used. During the preassessment 
    screen, trustee officials determine whether the discharge or release is 
    covered by CWA or CERCLA and whether they have a reasonable probability 
    of making a successful claim before expending efforts to carry out a 
    damage assessment. See 43 CFR 11.23(b). This determination appears to 
    be relevant regardless of the substantive assessment methods ultimately 
    used. Moreover, the determination whether to use a type A procedure, 
    type B procedures, or both is not made until the Assessment Plan Phase, 
    which follows the performance of the preassessment screen. See 43 CFR 
    11.33. The Department solicits comment on ways to reduce the burden of 
    the preassessment screen while at the same time ensuring that trustee 
    officials adequately consider the appropriateness of pursuing a damage 
    claim before proceeding with either a type A procedure, type B 
    procedures, or both.
    3. Coordination With Other Agencies
        A number of commenters requested additional guidance on 
    coordination among trustee agencies and between trustee agencies and 
    response agencies. Commenters raised questions about the lead 
    authorized official. Some commenters sought clarification of the role 
    of the lead authorized official. Others requested a prohibition against 
    the designation of a trustee official who is also a PRP as lead 
    authorized official.
        Suggestions for improved coordination between trustee and response 
    activities included: restricting the time allowed to conduct an 
    assessment in order to avoid potential conflicts with settlement 
    negotiations between response agencies and PRPs; requiring trustee 
    officials to participate in the remedial planning process; requiring 
    response agencies to coordinate with trustee officials; and authorizing 
    the On-Scene Coordinator to contact just one Federal trustee agency and 
    one State trustee agency and requiring that the contacted trustee 
    agencies notify all other trustee agencies.
        The Department's regulations already provide some guidance on 
    trustee coordination. See 43 CFR 11.32(a)(1). The regulations also 
    include discussions of coordination with response agencies. 43 CFR 
    11.23(f) and 11.31(a)(3). The Department intends to take a close look 
    at these coordination provisions during the biennial review. The 
    Department encourages commenters to provide suggestions on ways of 
    improving coordination among trustee agencies and between trustee and 
    response activities.
        NOAA's proposed OPA rule includes a model memorandum of 
    understanding designed to facilitate trustee coordination. See 59 FR 
    1185. Several States have been working to ensure better interagency 
    coordination. Also, as part of the recent National Performance Review 
    designed to streamline government operations, the Department developed 
    a number of recommendations concerning the improvement of trustee 
    coordination for natural resource damage assessments. The Department 
    intends to examine these efforts to see what lessons can be learned.
    4. Public and PRP Participation
        Several commenters voiced opinions about the opportunity for public 
    and PRP participation in the assessment process. Some commenters 
    thought that additional opportunities for public input were necessary 
    while others stated that the existing opportunities for public 
    participation were excessive. Several commenters thought that the 
    Department should encourage earlier involvement of PRPs in assessments 
    to avoid duplication of effort. NOAA's proposed OPA rule includes a 
    model memorandum of understanding for trustee officials and PRPs to use 
    when conducting joint assessments. 59 FR 1187.
        With regard to public participation, the Department's regulations 
    require that the public be given an opportunity to review and comment 
    on the Assessment Plan, including the Restoration and Compensation 
    Determination Plan, as well as the post-assessment Restoration Plan. 
    See 43 CFR 11.32(c), 11.81(d)(2), and 11.93(a), as amended by 59 FR 
    14283, and 14287.
        With regard to PRP participation, the Department's regulations 
    require that trustee officials provide PRPs with a Notice of Intent to 
    Perform an Assessment before beginning an assessment and invite the 
    participation of the PRPs. See 43 CFR 11.32(a)(2), as amended by 59 FR 
    14282. Trustee officials are also required to make the Assessment Plan 
    available to PRPs for review and comment. See 43 CFR 11.32(c). Finally, 
    trustee officials are authorized to allow PRPs to perform assessment 
    work. See 43 CFR 11.32(d).
        Determining the appropriate level of public and PRP participation 
    in the natural resource damage assessment process requires balancing 
    the interests of the public, the PRPs, and the trustee officials. The 
    Department solicits comment on whether the regulations strike the 
    appropriate balance and, if not, how the regulations could be revised 
    to strike a more appropriate balance.
    5. Optional Nature of Regulations
        The Department's regulations are not mandatory but must be followed 
    in order to obtain a rebuttable presumption. 43 CFR 11.10. Some 
    commenters have questioned the decision to make the regulations 
    optional. For example, one commenter suggested that Federal trustee 
    agencies be required to use the regulations unless all affected 
    trustees agree otherwise. The Department solicits additional comment on 
    whether to require trustee officials to use the regulations when they 
    pursue a claim for natural resource damages under CERCLA.
    6. Settlement Procedures
        Several commenters have requested that the regulations address 
    settlement procedures. For example, when trustee officials use type B 
    procedures, they must develop a preliminary estimate of damages to help 
    scope the range of work appropriate during the Assessment Phase. See 43 
    CFR 11.35(a), as amended by 59 FR 14282. Some commenters have suggested 
    that trustee officials be encouraged to use the preliminary estimate of 
    damages to initiate settlement discussions. Other commenters have 
    suggested that trustee officials be encouraged to perform separate 
    assessments for each affected resource to facilitate settlement. NOAA's 
    proposed OPA rule includes guidance on settlement procedures. 59 FR 
    1171.
        The Department strongly supports and encourages the use of the 
    regulations as a framework for negotiated resolutions of natural 
    resource damage claims. The Department is concerned that establishment 
    of specific settlement procedures in the regulations might unduly 
    restrict the flexibility of negotiating parties. However, the 
    Department solicits comment on the need for and possible nature of 
    settlement guidance.
    7. Assessment Plan
        There have been several comments about the Assessment Plan. The 
    regulations require trustee officials to develop a quality assurance 
    and quality control (QA/QC) plan that satisfies the requirements listed 
    in guidance developed by the Environmental Protection Agency (EPA), if 
    that guidance is applicable. See 43 CFR 11.31(c)(2), as amended by 59 
    FR 14281. Some commenters thought that the reference to EPA guidance 
    was inappropriate.
        The Department notes that EPA's QA/QC guidance is a well-
    established standard. Moreover, the Department's regulations provide 
    that EPA guidance need only be followed if applicable. The Department 
    solicits comment on specific areas of concern with EPA's QA/QC 
    guidance.
        Some commenters questioned whether the requirement that the 
    Assessment Plan include information on sampling size, design, and 
    location and estimated recovery period was necessary. One commenter 
    stated that the Assessment Plan should include a summary of the nature 
    and extent of contamination to ensure that the approach used to assess 
    damages is commensurate with the potential impact on resources.
        The purpose of the Assessment Plan is to provide the public with a 
    description of, and to organize, the work that will be performed during 
    the Assessment Phase. Inclusion of information about sampling size, 
    design, and location and estimated recovery periods seems appropriate 
    to fulfill that purpose. On the other hand, since a natural resource 
    damage assessment focuses on the actual injuries to resources rather 
    than the level of chemical present, inclusion of information about the 
    nature and extent of contamination may not be essential. However, the 
    Department solicits additional comment on the appropriate scope and 
    level of detail of the Assessment Plan.
        Several commenters stated that the Department should take 
    precautions to ensure that trustee officials do not undertake basic 
    research when performing damage assessments. These commenters suggested 
    that the Department provide a list of sources of existing scientific 
    data and prohibit trustee officials from performing new research unless 
    there are no existing data regarding the effect of the particular 
    substance on the particular natural resources involved.
        The Department agrees that trustee officials should not undertake 
    unnecessary basic research and one of the purposes of requiring a 
    publicly available Assessment Plan is to protect against such research. 
    A master list of existing data sources across the full range of 
    potentially affected resources would be costly and time-consuming to 
    compile, virtually impossible to keep up to date, and might also stifle 
    development of new approaches. However, the Department solicits comment 
    on alternative ways of guarding against the performance of unnecessary 
    basic research.
    8. Post-Assessment Phase
        Several commenters sought additional guidance on post-assessment 
    activities. The Department's regulations already provide some guidance 
    on post-assessment activities. See 43 CFR 11.90-11.93, as amended by 59 
    FR 14287. The Department notes that developing guidance requires 
    balancing increased predictability against reduced flexibility to 
    respond to the unique features of the broad range of potential natural 
    resource damage cases. Thus, there is a limit to the level of 
    specificity that can be appropriately provided in the regulations. With 
    this in mind, the Department solicits comment on specific aspects of 
    the Post-assessment Phase that warrant additional guidance. The 
    Department also solicits comment on whether the guidance should be 
    incorporated in the regulations or in a separate guidance document.
        Commenters have sought additional clarification of the requirements 
    related to the establishment of a restoration account for recovered 
    damages. One commenter thought that the regulations should require 
    trustee officials to hold any collected damages in interest-bearing 
    accounts. Other commenters have asked whether joint damage recoveries 
    by co-trustee agencies can be placed in a single restoration account. 
    Trustee officials' authority to open various forms of accounts is 
    determined by applicable Federal, State, and tribal fiscal law. 
    Therefore, although nothing in the Department's regulations prevents 
    trustee officials from placing damage recoveries in an interest-bearing 
    account, the regulations do not require trustee officials to do so. 
    Instead, the regulations provide that when trustee officials do not 
    have the authority to place damage recoveries in an interest-bearing 
    account, they should adjust their damage claim to account for 
    inflation. 43 CFR 11.92(b), as amended by 59 FR 14287. Also, the 
    regulations neither prohibit nor require the opening of joint accounts. 
    The Department solicits comment on whether additional clarification of 
    the appropriate form of restoration accounts should be provided.
    9. Assessment Costs
        Many commenters sought additional clarification on the scope of 
    recoverable assessment costs. CERCLA provides that trustee officials 
    may only recover ``reasonable'' assessment costs. CERCLA sec. 
    107(f)(1). The Department's regulations include a definition of 
    ``reasonable cost.'' See 43 CFR 11.14(ee). Among other things, this 
    definition requires that the anticipated cost of the assessment be 
    expected to be less than the anticipated damage amount. Some commenters 
    have stated that this definition should be revised so that the 
    reasonableness of assessment costs is determined by comparing the cost 
    of each component of the assessment to the anticipated damages to be 
    determined by that component. NOAA's proposed OPA rule defines 
    ``reasonable cost of an assessment'' as those costs incurred in 
    performing an assessment in accordance with the OPA rule. 59 FR 1169. 
    The Department solicits comment on whether any revision of its 
    definition of ``reasonable cost'' is appropriate.
        The Department's regulations provide that trustee officials may 
    recover the ``reasonable and necessary'' costs of an assessment. See 43 
    CFR 11.15(a)(3)(ii), as amended by 59 FR 14281. Some commenters have 
    questioned whether this provision would require trustee officials to 
    demonstrate not only that their assessment costs were reasonable but 
    also that they were necessary. These commenters noted that CERCLA 
    merely requires trustee officials to demonstrate that their assessment 
    costs were reasonable.
        The reference to ``necessary'' assessment costs was not intended to 
    require trustee officials to make an additional demonstration beyond 
    that required by CERCLA. Therefore, the Department is considering 
    deleting the reference to ``necessary'' assessment costs.
        The Department's regulations provide examples of recoverable 
    assessment costs. See 43 CFR 11.15(a)(3)(ii), as amended by 59 FR 
    14281. Some commenters have suggested that the regulations be amended 
    to include a list of specific practices that would render assessment 
    costs unreasonable. The Department questions whether addition of such a 
    list would be workable or necessary.
        Several commenters questioned whether attorneys' fees were 
    recoverable assessment costs. The Department believes that trustee 
    officials will generally need the assistance of an interdisciplinary 
    team of experts when performing natural resource damage assessments. 
    The regulations do not restrict recoverable assessment costs to the 
    expenses of particular types of professionals. The Department's 
    regulations provide that recoverable assessment costs are ``limited to 
    those costs incurred or anticipated by the authorized official for, and 
    specifically allocable to, site-specific efforts taken in the 
    assessment of damages.'' 43 CFR 11.60(d)(2). Therefore, if attorneys 
    are involved in work specifically allocable to an assessment, the 
    resulting attorneys' fees are recoverable as assessment costs under the 
    regulations. The Department solicits comment on whether additional 
    guidance on the recoverability of attorneys' fees is warranted.
    
    B. Injury
    
        Some commenters have indicated that the injury definitions 
    contained in the Department's regulations should be relaxed. Several 
    commenters thought that trustee officials should be allowed to document 
    injury by measuring the mere presence of the oil or hazardous substance 
    in a natural resource. Other commenters have felt that the Department 
    should allow injury to be documented through a risk analysis.
        On the other hand, some commenters have advocated the development 
    of more restrictive injury definitions. Several commenters have 
    contended that trustee officials should be required to link the 
    specific substance found in a natural resource to that of the discharge 
    or release in question. Other commenters have suggested that injuries 
    should be limited to lost public uses of the natural resources.
        The regulations establish acceptance criteria for the development 
    of biological injury definitions. 43 CFR 11.62(f)(2). Some commenters 
    have stated that these criteria should be applied not only when a new 
    injury definition is developed but also each time trustee officials 
    document incident-specific injuries under existing injury definitions. 
    Others felt that the acceptance criteria should be applied to each 
    hazardous substance for which a particular biological injury definition 
    was to apply.
        NOAA has proposed standards for determining injury under OPA that 
    differ from those in the Department's regulations. See 59 FR 1178-1180.
        The Department intends to carefully examine the type B standards 
    and methods for determining injury during this review. The Department 
    encourages commenters to provide suggestions on injury determination 
    and quantification.
    
    C. Economics
    
    1. Compensable Value
        Several commenters sought clarification on the economic values that 
    are included in compensable value. Some commenters questioned when lost 
    economic rent constitutes a compensable value. The Department's 
    regulations provide that compensable value includes ``any economic rent 
    accruing to a private party because the Federal or State agency or 
    Indian tribe does not charge a fee or price for the use of the 
    resources.'' 43 CFR 11.83(c)(1), as amended by 59 FR 14286. The 
    Department's regulations also provide that compensable value includes 
    changes in consumer surplus. Some commenters requested clarification of 
    what constituted consumer surplus. The Department solicits comment on 
    whether the regulations should provide additional guidance on the 
    assessment of damages for lost economic rent and consumer surplus.
        A couple of commenters stated that compensable value should include 
    not only the value of services lost to humans but also the value of 
    services lost to other resources as a result of the injuries. Under the 
    Department's regulations, trustee officials may consider not only the 
    reduction in services to humans but also the reduction in services to 
    other resources when selecting appropriate restoration, rehabilitation, 
    replacement, and/or acquisition measures and estimating their costs. 
    However, compensable value may be calculated only for the resource 
    services lost to the public pending completion of restoration, 
    rehabilitation, replacement, and/or acquisition of equivalent 
    resources. See 43 CFR 11.83(c)(1), as amended by 59 FR 14286. The 
    Department notes that compensable value does account indirectly for 
    certain services lost to other resources. For example, compensable 
    value for lost fishing opportunities may reflect the results of food 
    web losses. If commenters think that additional values should be 
    included in compensable value, they should specify the values of 
    interest, explain the legal basis for including such values, and 
    provide specific suggestions on how those values should be measured.
        The Department's regulations provide that in assessments where the 
    scope of economic analysis is at the State level, only the compensable 
    value to the State should be counted. 43 CFR 11.84(h)(3), as amended by 
    59 FR 14287. Several commenters suggested that this provision be 
    revised to allow State trustee officials to assess and recover 
    compensable value for all individuals, not just those within the State. 
    The Department solicits comment on the appropriate scope of economic 
    analysis for all trustee officials.
    2. Guidance on Methodologies
        There were numerous requests for additional guidance on 
    implementation of the cost-estimating and valuation methodologies 
    listed in the regulations. With regard to cost-estimating 
    methodologies, some commenters have stated that the guidance provided 
    on the incorporation of uncertainty into cost estimates is inadequate. 
    See 43 CFR Sec. 11.84(d), as amended by 59 FR 14286-87. Other 
    commenters requested additional guidance on selection and use of cost-
    estimating methodologies.
        With regard to valuation methodologies, commenters raised concerns 
    about the possibility of double counting if a hedonic pricing 
    methodology is used. One commenter noted that the regulations state, 
    ``When regional travel cost models exist, they may be used if 
    appropriate.'' 43 CFR 11.83(c)(2)(iv), as amended by 59 FR 14286. This 
    commenter stated that this statement incorrectly implied that regional 
    cost models were more appropriate than other models. Another commenter 
    stated that use of the travel cost methodology should not be allowed 
    because the results of a travel cost model can be skewed by the actions 
    of one unusually avid traveler.
        The Department solicits comment on the need for and possible 
    content of guidance on implementation of cost-estimating methodologies. 
    The Department also solicits comment on the need for and possible 
    content of guidance on implementation of methodologies for valuing lost 
    use values. Commenters should restrict their remarks to the calculation 
    of lost use values, because, as noted above, the Department is 
    addressing the estimation of lost nonuse values in a separate 
    rulemaking. See 59 FR 23097.
    3. Willingness to Accept
        Several commenters suggested that trustee officials be allowed to 
    calculate compensable value by estimating the minimum amount of money 
    an individual would require once an injury occurred in order to be as 
    well off as before the injury occurred (willingness to accept). The 
    Department agrees that, since natural resources are held in trust for 
    the public, willingness to accept is the correct theoretical measure of 
    compensable value. However, because of the practical difficulties 
    entailed in reliably measuring willingness to accept, the Department's 
    regulations require the use of methodologies that measure the amount of 
    money an individual would be willing to pay to prevent a natural 
    resource injury (willingness to pay). 43 CFR 11.83(c)(2), as amended by 
    59 FR 14286. The Department solicits comment on whether reliable 
    methods exist for measuring willingness to accept. The Department also 
    solicits comment on the conditions under which willingness to accept 
    rather than willingness to pay would, in theory, result in 
    significantly different estimates of compensable value.
    4. Discount Rate
        The Department's regulations provide that trustee officials should 
    discount the value of future costs and losses using the discount rate 
    specified in the Office of Management and Budget Circular A-94 (OMB 
    Circular A-94), dated March 27, 1972, which was ten percent. 43 CFR 
    11.84(e)(2). OMB Circular A-94 has been revised. The current version, 
    dated October 29, 1992, indicates that the discount rate for public 
    investment is 7 percent.
        The Department is soliciting comment on whether use of a seven 
    percent discount rate (the current value in Circular A-94) is 
    appropriate or whether trustee officials should be allowed to use a 
    different discount rate. A possible alternative discount rate for 
    future public losses of natural resources is the consumer rate of time 
    preference, which is the rate of interest at which an individual would 
    be indifferent between consuming goods now and postponing consumption 
    to a later date. Interest rates on investments with little or no 
    default risk, such as U.S. Treasury bonds, provide an estimate of the 
    consumer rate of time preference. The Department solicits comment on 
    whether trustee officials should be allowed to use a discount rate 
    based on the U.S. Treasury borrowing rate on marketable securities with 
    maturities comparable to the period over which future losses will 
    occur. Such an approach would be consistent with that proposed by NOAA 
    under OPA. See 59 FR 1184. Information on U.S. Treasury borrowing rates 
    on marketable securities is provided in Appendix C of OMB Circular A-
    94.
    5. Cost-Effectiveness
        The Department's regulations define ``cost-effectiveness'' to mean 
    that ``when two or more activities provide the same or a similar level 
    of benefits, the least costly activity providing that level of benefits 
    will be selected.'' 43 CFR Sec. 11.14(j). Commenters have expressed 
    confusion over the difference between cost effectiveness and 
    maximization of net benefits. Consideration of cost effectiveness 
    involves comparing activities that provide the same or a similar level 
    of benefits. In contrast, consideration of net benefits can be used to 
    compare activities that provide substantially different levels of 
    benefits.
        Another commenter stated that the definition of ``cost-
    effectiveness'' should be changed to delete the reference to 
    ``similar'' levels of benefits, in order to ensure full restoration, 
    rehabilitation, replacement, and/or acquisition of equivalent 
    resources.
        Use of the phrase ``same or similar'' was not intended to force 
    trustee officials into using methods that produce lower benefits. 
    Instead, the term merely reflects the fact that in the damage 
    assessment context trustee officials will often be comparing methods 
    that do not produce exactly the same benefits.
        The Department solicits comment on whether additional clarification 
    is warranted.
    
    D. Legal Topics
    
    1. Judicial Review
        One significant area of discussion has been judicial review of 
    damage assessments. CERCLA provides that any determination or 
    assessment of damages performed ``in accordance with'' the natural 
    resource damage assessment regulations ``shall have the force and 
    effect of a rebuttable presumption on behalf of the trustee.'' CERCLA 
    sec. 107(f)(2)(C). This provision is incorporated into the Department's 
    regulations without further clarification. See 43 CFR Sec. 11.91(c). 
    Commenters have asked the Department to define the term ``rebuttable 
    presumption'' and clarify when and to which aspects of the assessment 
    the rebuttable presumption applies. Some commenters have questioned 
    whether the phrase ``in accordance with'' the regulations allows 
    trustee officials to obtain a rebuttable presumption for any portion of 
    an assessment that complies with the regulations or whether it 
    restricts the rebuttable presumption to those assessments that follow 
    all portions of the regulations.
        The Department's regulations provide both an administrative process 
    for development and review of documentation as well as a range of 
    alternative methodologies for the actual determination of injuries and 
    damages. The Department believes that in order to obtain a rebuttable 
    presumption, a trustee official must follow the entire administrative 
    process set forth in the regulations. If the trustee official has 
    followed the administrative process, the rebuttable presumption 
    attaches to those components of the damage claim that were calculated 
    through the appropriate use of any of the methodologies described in 
    the regulations. However, trustee officials are not required to use all 
    of the listed methodologies in order to obtain a rebuttable 
    presumption. The Department solicits comment on this interpretation and 
    on whether additional clarification of the effect of the rebuttable 
    presumption is warranted.
        There have been comments about whether judicial review of an 
    assessment should be limited to an administrative record. Under NOAA's 
    proposed OPA rule, judicial review of assessment costs and estimated 
    costs of restoration, rehabilitation, replacement, and/or acquisition 
    of equivalent resources would be conducted on an administrative record. 
    59 FR 1185. The Department solicits comment on whether a similar 
    provision should be included in its regulations. The Department also 
    solicits comment on whether judicial review of compensable value should 
    be conducted on an administrative record.
    2. Effect of Amendments
        Commenters have expressed confusion over the applicability of 
    amendments of the natural resource damage assessment regulations to 
    ongoing damage assessments that were started before the amendments 
    became effective. The Department solicits comment on whether it should 
    clarify that trustee officials are entitled to a rebuttable presumption 
    so long as their assessments are in accordance with the regulations as 
    they were in effect at the time that the assessments began.
    3. Limits of Liability
        Some commenters have sought clarification of various statutory 
    limitations on liability, including the ceilings set forth in section 
    107(c) of CERCLA and the provision in section 107(f)(1) that excludes 
    natural resource damages if those damages and the release that caused 
    those damages occurred wholly before the enactment of CERCLA. The 
    Department's regulations incorporate the statutory limitations on 
    liability but do not provide any clarification of those limitations. 43 
    CFR 11.15(b) and 11.24(b)(1). The Department will consider the 
    development of additional guidance if commenters identify specific 
    areas of concern.
    4. Double Recovery
        Some commenters have sought clarification of the prohibition 
    against ``double recovery'' of damages contained in section 107(f)(1) 
    of CERCLA. The Department's regulations incorporate this prohibition. 
    43 CFR Secs. 11.15(d) and 11.84(c). Double recovery refers to the 
    recovery of two or more damage amounts to restore, rehabilitate, 
    replace, and/or acquire the equivalent of the same injured resource or 
    lost service or to compensate for the same lost public value. The 
    Department will consider the development of additional guidance if 
    commenters identify specific areas of concern.
    5. Threatened Releases and Discharges
        Another area of discussion has been the recovery of natural 
    resource damages caused by the threat of a release or discharge. 
    Section 107(a)(4) of CERCLA refers to liability for ``a release or a 
    threatened release.'' However, section 107(a)(4)(C) refers to damages 
    for injury to, destruction of, or loss of natural resources ``resulting 
    from such a release.'' Also, section 301(c) of CERCLA authorizes the 
    Department to develop regulations for assessment of ``damages for 
    injury to, destruction of, or loss of natural resources resulting from 
    a release of oil or a hazardous substance.''
        The Department's regulations address only damages resulting from an 
    actual release or discharge. NOAA's proposed rule, relying on section 
    1002(a) of OPA, would allow for the assessment of diminished use of a 
    resource resulting from the threat of a discharge. 59 FR 1169. The 
    Department solicits comment on whether CERCLA allows for recovery of 
    damages resulting from a threatened release and whether the 
    Department's regulations should be revised to allow for the assessment 
    of damages resulting from a threatened release or discharge. The 
    Department also solicits examples of the types of damages that might be 
    assessed in the case of a threatened discharge or release.
    6. Archaeological and Cultural Resources
        Several commenters have questioned whether CERCLA authorizes the 
    recovery of damages for injury of archaeological and cultural 
    resources. The Department believes that ``archaeological'' and 
    ``cultural'' resources do not constitute ``natural resources'' as 
    defined by CERCLA. However, the Department's regulations do permit 
    trustee officials to include the loss of archaeological and cultural 
    services provided by a natural resource in a natural resource damage 
    assessment.
    7. Unused Damage Awards
        Some commenters have suggested that the statutory requirement that 
    damages be spent to restore, rehabilitate, replace, and/or acquire the 
    equivalent of the injured resources dictates that any sums not used in 
    this manner be returned to the PRPs. The Department's regulations 
    provide that collected damages may only be used to fund actions 
    described in the Restoration Plan and do not address the disposition of 
    any ``excess'' funds. See 43 CFR 11.92(c).
        The Department notes that CERCLA requires all collected damages to 
    be spent on restoration, rehabilitation, replacement, and/or 
    acquisition of equivalent resources, which includes mitigation of the 
    public loss of services during the recovery period. Therefore, all 
    funds should be used for restoration, rehabilitation, replacement, and/
    or acquisition of equivalent resources.
    8. NEPA
        Several commenters sought clarification of whether the National 
    Environmental Policy Act (NEPA) applies to assessments or restorations 
    performed in accordance with the regulations. The Department does not 
    anticipate addressing the applicability of NEPA in the damage 
    assessment regulations. However, the Department believes that the 
    information needed for the Restoration and Compensation Determination 
    Plan should fulfill the requirements of NEPA, with equivalent 
    opportunities for public input. Thus if NEPA were applicable to an 
    assessment or restoration activity, the Department believes that 
    appropriate and timely information would be available.
    9. Consideration of Benefits
        Some commenters stated that the Department's regulations should be 
    revised to require trustee officials to offset any damages resulting 
    from the discharge or release with any benefits produced by the 
    discharge or release. The Department solicits additional comment.
    10. Tribal Trustees
        A number of commenters have sought to ensure that the interests of 
    tribal entities are adequately addressed in the Department's 
    regulations. A number of commenters expressed concern over the 
    treatment of tribal values, including the values associated with tribal 
    cultural resources. As noted above, the Department believes that 
    ``cultural'' resources, including tribal cultural resources, do not 
    constitute ``natural resources'' as defined by CERCLA. However, the 
    Department's regulations do permit trustee officials to include the 
    loss of cultural services provided by a natural resource in a natural 
    resource damage assessment.
        Other commenters suggested that the Department's fiduciary 
    responsibility to Indian tribes extends to financing natural resource 
    damage assessments involving tribal resources. Although the Department 
    exercises a fiduciary responsibility as trustee for Indian resources, 
    the Department believes that discussion of funding mechanisms for 
    damage assessment activities conducted by Indian tribes is not 
    appropriate for this rulemaking, except as addressed in the law and 
    regulation regarding the liability of PRPs and use of recovered sums.
        One commenter stated that CERCLA grants a rebuttable presumption to 
    assessments performed by tribal trustee officials. This commenter 
    stated that when CERCLA was amended by the Superfund Amendments and 
    Reauthorization Act (SARA), Congress intended to grant tribes the same 
    authority as States in the area of natural resource trustee activities. 
    The commenter further noted that under established case law concerning 
    the Federal government's fiduciary responsibility to tribes, any 
    ambiguity in the statute concerning tribes' right to the rebuttable 
    presumption must be construed in favor of the tribes.
        The Department notes that the regulations were revised in 1988 to 
    reflect the SARA amendment to CERCLA granting a rebuttable presumption 
    to natural resource damage assessments performed by State trustee 
    officials. See 43 CFR 11.91(c). At that time and in subsequent Federal 
    Register notices, the Department has taken the position that SARA did 
    not extend the rebuttable presumption to assessments performed by 
    tribal trustee officials and that granting a rebuttable presumption to 
    tribes will require a legislative change.
    
    E. Restoration, Rehabilitation, Replacement, and/or Acquisition of 
    Equivalent Resources
    
    1. Types of Alternatives
        Some commenters have suggested that the regulations should 
    encourage trustee officials to select restoration and rehabilitation 
    alternatives rather than replacement or acquisition alternatives. The 
    Department's regulations do not indicate a preference for any 
    particular type of restoration, rehabilitation, replacement, or 
    acquisition alternative. The Department solicits comment on whether it 
    has the authority, and whether it is appropriate, to develop and 
    require adherence to a priority system for selecting a restoration, 
    rehabilitation, replacement, and/or acquisition alternative.
        The Department's regulations provide that Federal trustee officials 
    may not select an alternative that requires acquisition of land for 
    Federal management, unless restoration, rehabilitation and replacement 
    are not possible. 43 CFR 11.82(e), as amended by 59 FR 14285. Some 
    commenters supported this restriction and requested that it be extended 
    to State and tribal natural resource trustees. Other commenters thought 
    that the restriction should be eliminated altogether. The Department is 
    interested in comments on this issue.
        Some commenters stated that the regulations should clearly 
    authorize trustee officials to choose a natural recovery alternative 
    when selecting a restoration, rehabilitation, replacement, and/or 
    acquisition alternative. The Department believes that the regulations 
    already authorize trustee officials to select a natural recovery 
    alternative when appropriate. The Department's regulations explicitly 
    require trustee officials to consider a ``No Action-Natural Recovery'' 
    alternative. 43 CFR 11.82(c)(2), as amended by 59 FR 14284.
    2. Guidance on Selection of an Alternative
        Several commenters have requested guidance on selection of a 
    restoration, rehabilitation, replacement, and/or acquisition 
    alternative. In particular, some commenters thought that the Department 
    should provide guidance on how trustee officials could maximize the 
    opportunities for natural recovery.
        The Department's regulations already provide some guidance on the 
    selection of a restoration, rehabilitation, replacement, and/or 
    acquisition alternative. See 43 CFR 11.82, as amended by 59 FR 14284-
    85. The Department's regulations require trustee officials to evaluate 
    a reasonable number of restoration, rehabilitation, replacement, and/or 
    acquisition alternatives, including natural recovery. The Department's 
    regulations also provide a number of factors that trustee officials 
    must consider when selecting an alternative. NOAA's proposed OPA rule 
    includes a similar list of factors and contains guidance on determining 
    when to select an alternative that relies on natural recovery. 59 FR 
    1181. NOAA has developed a draft guidance document on restoration 
    activities. 59 FR 1065.
        The Department notes that developing guidance requires balancing 
    increased predictability against reduced flexibility to respond to the 
    unique features of the broad range of potential natural resource damage 
    cases. Thus, there is a limit to the level of specificity that can be 
    appropriately provided in the regulations. With this in mind, the 
    Department solicits comment on specific aspects of the selection 
    process that warrant additional guidance. The Department solicits 
    comment on whether the guidance should be incorporated in the 
    regulations or in a separate guidance document. The Department also 
    intends to consider the appropriateness of offering guidance on 
    available restoration and rehabilitation techniques and would 
    appreciate information on appropriate case studies demonstrating 
    successful application of restoration and rehabilitation measures.
    3. Specific Selection Factors
        Under the Department's regulations, one of the factors that trustee 
    officials must consider when selecting a restoration, rehabilitation, 
    replacement, and/or acquisition alternative is the relationship between 
    estimated costs and estimated benefits. 43 CFR 11.82(d)(2), as amended 
    by 59 FR 14285. Total damages will depend on the sum of compensable 
    value and restoration, rehabilitation, replacement, and/or acquisition 
    costs. Often there will be tradeoffs between compensable value and 
    restoration, rehabilitation, replacement, and/or acquisition costs. For 
    example, a fast-paced restoration, rehabilitation, replacement, and/or 
    acquisition alternative may result in a lower level of interim lost 
    use, and thus reduce associated compensable values. However, 
    implementation of such an alternative may result in significantly 
    higher restoration, rehabilitation, replacement, and/or acquisition 
    costs. In some cases, there may be sufficient data to demonstrate that 
    some restoration, rehabilitation, replacement, and/or acquisition 
    alternatives result in substantially lower total damages than others.
        NOAA has solicited comment on whether, under OPA, trustee officials 
    should be required to explain their rationale if they select a 
    restoration, rehabilitation, replacement, and/or acquisition 
    alternative that does not minimize total damages. 59 FR 1134. The 
    Department solicits comment on whether a similar requirement should be 
    added to the Department's regulations.
        A commenter suggested that socioeconomic effects of restoration, 
    rehabilitation, replacement, and/or acquisition alternatives might be 
    added to the list of factors that trustee officials are to consider in 
    making their selection among alternatives. The Department's regulations 
    provide that trustee officials may consider all relevant considerations 
    when selecting a restoration, rehabilitation, replacement, and/or 
    acquisition alternative. 43 CFR 11.82(d), as amended by 59 FR 14284-85. 
    Therefore, trustee officials already have the ability to consider 
    socioeconomic effects if relevant.
    4. Services Versus Resources
        Several commenters expressed confusion over whether the Department 
    intended restoration, rehabilitation, replacement, and/or acquisition 
    of the equivalent to be measured in terms of the services provided by a 
    resource, the resource itself, or both. Several commenters noted 
    apparent inconsistencies in the regulations.
        Some commenters stated that restoration, rehabilitation, 
    replacement, and/or acquisition of the equivalent should be strictly 
    limited to the services provided by the resource. For example, some 
    commenters believed that if an injured stream was used for fishing and 
    nothing else, PRPs should only be liable for the cost of cleaning that 
    stream to the point where fishing opportunities are returned to 
    baseline. These commenters thought that requiring restoration, 
    rehabilitation, replacement, and/or acquisition of the equivalent of 
    both services and the resource itself would create economic 
    inefficiencies and would constitute double counting.
        Other commenters indicated that measuring restoration, 
    rehabilitation, replacement, and/or acquisition of the equivalent in 
    terms of services only would fail to fully compensate the public. These 
    commenters expressed concern that using services alone as a measurement 
    could prevent trustee officials from attaining complete restoration, 
    rehabilitation, replacement, and/or acquisition of the equivalent.
        The Department intends to carefully review the use of the terms 
    ``resources'' and ``services'' in this biennial review. The Department 
    solicits comment on whether restoration, rehabilitation, replacement, 
    and/or acquisition should be measured in terms of services, resources, 
    or both. The Department also solicits comment on the definition of 
    ``services'' and whether it should be modified or additional concepts 
    should be developed or defined to further clarify this issue.
    5. Committed Use
        One commenter stated that the concept of committed use should not 
    apply to restoration, rehabilitation, replacement, and/or acquisition 
    of equivalent resources, in the sense that restoration of a resource or 
    service to a level of environmental quality beyond that needed to 
    support existing committed uses should not be required.
        ``Committed use'' is defined as a current or planned public use for 
    which there is a documented commitment established. 43 CFR 11.14(h). 
    Under the Department's regulations, the concept of committed use 
    applies only to the calculation of compensable value and does not 
    affect the appropriate level of restoration, rehabilitation, 
    replacement, and/or acquisition of equivalent resources. See 43 CFR 
    11.84(b)(2).
        The committed use requirement was designed to prevent trustee 
    officials from assessing compensable value for purely speculative uses 
    of a resource. When measuring restoration, rehabilitation, replacement, 
    and/or acquisition, the guiding concept is whether baseline conditions 
    have been reestablished, irrespective of consideration of compensable 
    values. Failure to account for potential services when measuring 
    restoration, rehabilitation, replacement, and/or acquisition of 
    equivalent resources could violate Ohio v. Interior, which stated:
    
        Our decision to uphold the ``committed use'' requirement is 
    premised on our interpretation of the regulation to mean that a 
    trustee is not prohibited from recovering costs of restoring or 
    replacing a natural resource even when that resource has no 
    documented ``committed use.'' 880 F.2d at 462.
    6. Implementation of an Alternative
        A commenter said there should be provisions for starting 
    restoration, rehabilitation, replacement, and/or acquisition activities 
    while the damage assessment is still under way. The Department's 
    regulations provide for implementation of emergency restorations in 
    appropriate circumstances, generally limited to actions necessary to 
    abate an emergency situation. 43 CFR 11.21. Other than for emergency 
    restorations, starting restoration, rehabilitation, replacement, and/or 
    acquisition activities while damage assessment is underway, while not 
    precluded, is not expressly discussed in the regulations. However, 
    trustee officials may not expend funds received for restoration, 
    rehabilitation, replacement, and/or acquisition of equivalent resources 
    prior to developing a Restoration Plan and making it available for 
    public comment and review. 43 CFR 11.92(c); CERCLA sec. 111(i).
        The assessment process is designed, in part, to ensure that 
    appropriate and efficient measures to accomplish restoration, 
    rehabilitation, replacement, and/or acquisition of equivalent resources 
    are adopted. Unless there is a compelling reason for early initiation 
    of restoration, rehabilitation, replacement, and/or acquisition 
    activities, the Department believes that the administrative process 
    established under the regulations should be followed. This approach is 
    similar to that provided under other existing legislation and 
    regulation (e.g., NEPA and the Administrative Procedure Act) whereby 
    there are general and specific constraints on taking certain actions or 
    making irrevocable decisions or irretrievable commitments of resources 
    prior to completion of appropriate planning and public involvement. 
    However, if initiation of certain restoration, rehabilitation, 
    replacement, and/or acquisition actions would not constrain 
    decisionmaking following completion of the assessment process, and if 
    the public was given adequate opportunity to comment on the proposed 
    actions consistent with CERCLA section 111(i), such actions could be 
    appropriate.
        Commenters have also sought clarification of 43 CFR 11.21 (b) and 
    (c), which provide that a trustee official may undertake emergency 
    restoration actions ``consistent with its existing authority.'' 
    Existing 43 CFR 11.21 was developed in recognition of section 111(i) of 
    CERCLA, which provides that trustee officials need not develop a 
    restoration plan subject to public comment prior to taking emergency 
    actions. The Department does not believe that section 111(i) of CERCLA 
    provides trustee agencies with independent authority to take action 
    they would not otherwise have authority to take. The Department 
    solicits comment on whether additional clarification is warranted.
        One commenter asked the Department to recognize the right of co-
    trustees to spend collected damages on implementation of different 
    Restoration Plans. While the Department's regulations require trustee 
    coordination and encourage joint development and implementation of 
    restoration, rehabilitation, replacement, and/or acquisition actions, 
    nothing in the regulations prohibits co-trustees from implementing 
    different Restoration Plans. The Department solicits further comment on 
    this issue.
        A few commenters requested guidance on determining when 
    restoration, rehabilitation, replacement, and/or acquisition of 
    equivalent resources is complete. Some commenters suggested that 
    trustee officials provide PRPs with a certification when restoration, 
    rehabilitation, replacement, and/or acquisition of equivalent resources 
    is essentially completed so that PRPs will not remain liable 
    indefinitely.
        The Department's regulations provide that the recovery period is 
    the time until baseline conditions have been reestablished. 43 CFR 
    11.73(a), as amended by 59 FR 14283. It is up to the trustee officials, 
    and in the case of settlements the joint agreement of the trustee 
    officials and the PRPs, whether a site-specific definition of 
    completeness should be included in the Restoration Plan. The Department 
    has not considered it necessary to require trustee officials to provide 
    PRPs with a certification when restoration, rehabilitation, 
    replacement, and/or acquisition of equivalent resources is essentially 
    completed. The extent of a PRP's continuing liability after damages 
    have been recovered by the trustee officials depends on the terms of 
    the judgment or settlement agreement.
