SUPPLEMENTARY INFORMATION:

I. Authority

33 U.S.C. 1251 et seq.; 33 U.S.C. 2720; E.O. 12777 (October 18, 1991), 3 CFR, 1991 Comp., p. 351.

II. Background

On July 17, 2002, the Agency published a final rule that amended the SPCC regulations (see 67 FR 47042). The rule became effective on August 16, 2002. The final rule included compliance dates in § 112.3 for preparing, amending, and implementing SPCC Plans. The original compliance dates were amended on January 9, 2003 (see 68 FR 1348), again on April 17, 2003 (see 68 FR 18890), and a third time on August 11, 2004 (see 69 FR 48794).

Under the regulations in effect prior to this final rule, § 112.3(a) and (b) required a facility that was in operation on or before August 16, 2002 to make any necessary amendments to its SPCC Plan by February 17, 2006, and to fully implement its SPCC Plan by August 18, 2006. A facility that came into operation after August 16, 2002, but before August 18, 2006, was required to prepare and fully implement an SPCC Plan on or before August 18, 2006. Thus, for facilities in operation on or before August 16, 2002, the regulations provided a six-month period between the compliance date for Plan amendment and the compliance date for Plan implementation. In addition, § 112.3(c) required onshore and offshore mobile facilities to prepare or amend and implement SPCC Plans on or before August 18, 2006.

On December 12, 2005, the Agency published in the Federal Register a proposed rule that would amend the SPCC requirements in several areas (see 70 FR 73524). Specifically, the proposal would allow owners and operators of facilities with an oil storage capacity of 10,000 gallons or less, that also meet other qualifying criteria, the option of self-certification of their SPCC Plans (in lieu of review and certification by a Professional Engineer); it would provide facilities with certain types of oil-filled operational equipment an alternative to the secondary containment requirement that would not require a determination of impracticability; it would define airport mobile refuelers, and exempt such vehicles meeting the definition from the specifically sized secondary containment requirements for bulk storage containers; it would amend the requirements for animal fats and vegetable oils (AFVOs) by removing certain sections of the regulations in Subpart C of Part 112 that do not apply to facilities that handle, store, or transport AFVOs; and it would define farms, and would provide a separate extension of the compliance dates for certain farms.^[1]

On the same day, but in a separate notice in the Federal Register (see 70 FR 73518), the Agency also proposed to extend the dates in § 112.3(a), (b), and (c) by which a facility must prepare or amend and implement its SPCC Plan. Under the proposed extension rule, a facility that was in operation on or before August 16, 2002 would have to make any necessary amendments to its SPCC Plan, and implement that Plan, on or before October 31, 2007. Likewise, a facility that came into operation after August 16, 2002 would have to prepare and implement an SPCC Plan on or before October 31, 2007. Finally, a mobile facility would have to prepare or amend and implement an SPCC Plan on or before October 31, 2007.

The Agency's proposal to extend the compliance dates in § 112.3 (which is made final in today's notice) was designed to allow the Agency time to take final action on the proposed amendments to the SPCC requirements before owners and operators are required to prepare, amend, and implement their SPCC Plans. The Agency believed that the extension was appropriate to allow owners and operators to take advantage of any modifications that would be provided by a final SPCC amendment rule. In addition, the Agency believed that the extension would allow the regulated community the opportunity to understand the material presented in its newly released guidance “SPCC Guidance for Regional Inspectors” ^[2] before preparing or amending their SPCC Plans. Finally, the Agency believed that the proposed extension was necessary for facilities that might have difficulty meeting the upcoming compliance dates because they were adversely affected by the recent hurricanes.

III. Summary of This Final Rule

This final rule extends the dates in § 112.3 by which owners and operators of facilities must prepare or amend their SPCC Plans as proposed. Under the new § 112.3(a), a facility that was in operation on or before August 16, 2002 must make any necessary amendments to its SPCC Plan, and implement that Plan, on or before October 31, 2007. Under the new § 112.3(b), a facility that came into operation after August 16, 2002 must also prepare and implement an SPCC Plan on or before October 31, 2007. Finally, under the new § 112.3(c), a mobile facility must prepare or amend and implement an SPCC Plan on or before October 31, 2007.

This rule is effective immediately. Section 553(d) of the Administrative Procedures Act requires 30-days notice before the effective date of a final rule. However, section 553(d)(1) allows an exception to the 30-day notice where a rule relieves a restriction. Since this final rule relieves a restriction, the Agency invokes section 553(d)(1) to allow an immediate effective date.

It should be noted that today's compliance date extension affects only requirements of the July 2002 final SPCC rule that impose new or more stringent compliance obligations than did the 1973 SPCC rule. Any provision in the July 2002 rule that provides regulatory relief is not affected by these compliance date extensions because such provisions are not ones for which it would be “necessary” to amend existing Plans “to ensure compliance with” the July 2002 amendments (see § 112.3). This issue was discussed by the Agency in two previous extension notices on April 17, 2003 (see 68 FR 18890, at 18892-3), and on August 11, 2004 (see 69 FR 48794, at 48796).

IV. Response to Comment

The Agency received approximately 80 comments on the proposed rule. The discussion below summarizes and responds to the major comments received. A more complete response to comments can be found in the docket for this rulemaking, EPA-HQ-OPA-2005-0003.

The majority of commenters supported the Agency's proposal to extend the compliance dates in § 112.3. They agreed with the Agency that the extension was necessary to allow owners and operators the opportunity to take advantage of any modifications that might be provided by an amendment to the SPCC rule (see discussion in section II). Of those who supported an extension of the compliance dates, some commenters agreed with extending the compliance dates as proposed, and others opposed the proposed length of the extension.

A number of commenters requested that the Agency incorporate flexibility into the compliance dates in § 112.3, by extending them until October 31, 2007, or until a date no less than one year following implementation of the final SPCC amendment rule, whichever is later. Commenters believed that, since the date for a final SPCC amendment rule is uncertain, setting a compliance date of October 31, 2007 does not guarantee owners and operators a full year between promulgation of a final rule and the compliance dates in § 112.3. These commenters believe it is important to coordinate the compliance dates in § 112.3 with a final SPCC amendment rule.

The Agency is reluctant to proceed as these commenters suggested and set uncertain compliance dates in § 112.3. At the same time, the Agency recognizes that the regulated community needs adequate time after EPA takes final action on the proposed amendments to the SPCC Plan requirements to amend or prepare their SPCC Plans and to implement them. The Agency agrees that one year is a reasonable period of time to allow for preparing, amending, and implementing SPCC Plans following final Agency action on the proposed amendments to the SPCC rule. The Agency plans to develop and publish a Federal Register notice taking final action on the December 12, 2005 proposal as soon as possible. At this time, based on the information at hand, the Agency believes that extending the compliance dates in § 112.3 until October 31, 2007 will allow owners and operators an adequate interval to comply with the SPCC rule. Regarding modifications of the SPCC regulations, to the extent practicable, EPA will establish deadlines for compliance implementation that commence one year after promulgating the regulatory revisions.

Other commenters objected to the Agency's proposal to eliminate the six-month interim period in § 112.3(a) between the compliance dates for Plan amendment and implementation. Those commenters requested that the date for implementing amended SPCC Plans be revised to include a six-month period after the October 31, 2007 date for Plan amendment.

The Agency disagrees with these commenters. For the reasons discussed above, the Agency believes the October 31, 2007 date for Plan implementation is adequate. The effect of the Agency's decision to eliminate the gap between Plan preparation or amendment and implementation was to allow additional time for Plan preparation or amendment. The Agency believes that this approach, which allows owners and operators flexibility, makes sense given that owners and operators are not required to submit their SPCC Plans to the Agency.

Several commenters conditioned their support of the proposed compliance date extensions on the Agency's timely resolution of issues related to regulation of animal fats and vegetable oils (AFVOs). These commenters were concerned that the Agency has not yet developed differentiated requirements for AFVOs, and some suggested that the Agency develop a timeframe to do so.

In the December 12, 2005 SPCC amendment proposed rule, the Agency requested information that would support differentiated SPCC requirements for AFVOs (see 70 FR 73542, at 73541). The Agency is not prepared, at this time, to determine whether that request for comment will produce information that is appropriate or adequate for development of differentiated requirements for AFVOs. Thus, the Agency believes it would be inappropriate to condition the compliance dates in § 112.3 on such uncertain factors. Further, issues specific to the regulation of AFVOs are outside the scope of this extension. The Agency will review and give full consideration to all comments it receives related to AFVOs, and address those comments when it has had a chance to assess them and any data provided.

Finally, some commenters objected to extending the compliance dates in § 112.3. Generally, those commenters believed that extension of the dates would delay development and implementation of SPCC Plans, which are necessary for protection of human health and the environment. Further, they raised concerns that extending the compliance dates only encourages non-compliance.

For example, one commenter argued that it is unnecessary and absurd to extend the compliance dates a third time. The commenter pointed out that this rule would extend compliance to a time four years after the 2002 SPCC rule should have first been effective, and almost 35 years after the SPCC rules were first promulgated. The commenter believed that facilities should already be in compliance with the 1973 rules, and consequently should be in compliance with the rule changes proposed by the Agency because they primarily reduce the requirements for regulated facilities. The commenter also believed that most regulated facilities already have developed and implemented SPCC plans to comply with the earlier compliance dates that were subsequently extended. The commenter believed that these facilities are ready to meet their obligations to prevent oil spills and other releases, and that it is entirely unnecessary to extend the compliance dates when most facilities have developed and implemented Plans. Finally, the commenter anticipated that extending the compliance dates will extend the Agency's practice of reduced inspections and enforcement at SPCC regulated facilities, continuing the increased likelihood of oil releases and endangerment of facility personnel and neighboring communities. By extending the compliance dates, the commenter was concerned that the Agency would allow noncompliant facilities that have not put SPCC Plans in place to continue to operate and endanger human health and the environment.

The Agency believes that it is in the best interest of both the regulated community and the environment to address areas of confusion that arose after promulgation of the 2002 amendments. By promulgating a proposal intended to clarify requirements and reduce burdens, particularly on small businesses, and by making the SPCC Inspectors Guidance available to the regulated community, the Agency believes that a more effective and complete implementation of the SPCC regulation and improved environmental protection will ultimately result. The Agency also believes that the regulated community needs the additional time allowed by the extension in order to better take advantage of the guidance and any further amendments that are promulgated and that the benefits of this extension outweighs the concerns raised by commentors of increased administrative burdens.

V. Statutory and Executive Order Reviews

A. Executive Order 12866—Regulatory Planning and Review

Under Executive Order 12866, (58 FR 51735, October 4, 1993), the Agency must determine whether a regulatory action is “significant” and therefore subject to Office of Management and Budget (OMB) review and the requirements of the Executive Order. The order defines “significant regulatory action” as one that is likely to result in a rule that may:

(1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities;

(2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;

(3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or

(4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order.

Under the terms of Executive Order 12866, this action has been judged as not a “significant regulatory action” because it extends the compliance dates in § 112.3, but has no other substantive effect. However, because of its interconnection with the rulemaking proposed on December 12, 2005 (see discussion in section II), which is a significant action under the terms of Executive Order 12866, this action was nonetheless submitted to OMB for review.

B. Paperwork Reduction Act

This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. because this action does not change the requirements of the rule.

Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.

An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

C. Regulatory Flexibility Act

The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act, or any other statute, unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

For purposes of assessing the impacts of today's rule on small entities, small entity is defined as: (1) A small business as defined in the Small Business Administration's (SBA) regulations at 13 CFR 121.201—the SBA defines small businesses by category of business using North American Industry Classification System (NAICS) codes, and in the case of farms and production facilities, generally defines small businesses as having less than $500,000 in revenues or 500 employees, respectively; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise that is independently owned and operated and is not dominant in its field.

After considering the economic impacts of today's final rule on small entities, the Agency certifies that this action would not have a significant economic impact on a substantial number of small entities. In determining whether a rule has a significant economic impact on a substantial number of small entities, the impact of concern is any significant adverse economic impact on small entities, since the primary purpose of the regulatory flexibility analyses is to identify and address regulatory alternatives “which minimize any significant economic impact of the rule on small entities.” 5 U.S.C. 603 and 604. Thus, an agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, or otherwise has a positive economic effect on all of the small entities subject to the rule.

This rule relieves the regulatory burden for small entities by extending the compliance dates in § 112.3. After considering the economic impacts of today's rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities.

D. Unfunded Mandates Reform Act

Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of UMRA, EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with “Federal mandates” that may result in expenditures to State, local, and tribal governments, in the aggregate, or to the private sector, of $100 million or more in any one year. Before promulgating an EPA rule for which a written statement is needed, section 205 of UMRA generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows EPA to adopt an alternative other than the least costly, most-effective or least burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, it must have developed, under section 203 of UMRA, a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements.

EPA has determined that this rule does not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any one year. This rule would reduce burden and costs for all facilities.

EPA has determined that this rule contains no regulatory requirements that might significantly or uniquely affect small governments. As was explained above, the effect of the rule is to reduce burden and costs for all facilities, including small governments that are subject to the rule by extending the compliance dates.

E. Executive Order 13132—Federalism

Executive Order 13132, entitled “Federalism” (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.”

This rule does not have federalism implications. It does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. Under CWA section 311(o), States may impose additional requirements, including more stringent requirements, relating to the prevention of oil discharges to navigable waters. EPA encourages States to supplement the Federal SPCC regulation and recognizes that some States have more stringent requirements (56 FR 54612, October 22, 1991). This rule does not preempt State law or regulations. Thus, Executive Order 13132 does not apply to this rule.

F. Executive Order 13175—Consultation and Coordination With Indian Tribal Governments

On November 6, 2000, the President issued Executive Order 13175 (65 FR 67249) entitled, “Consultation and Coordination with Indian Tribal Governments.” Executive Order 13175 took effect on January 6, 2001, and revokes Executive Order 13084 (Tribal Consultation) as of that date.

Today's rule would not significantly or uniquely affect communities of Indian tribal governments. Therefore, the Agency has not consulted with a representative organization of tribal groups.

G. Executive Order 13045—Protection of Children From Environmental Health and Safety Risk

Executive Order 13045, “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997) applies to any rule that: (1) Is determined to be “economically significant” as defined under Executive Order 12866; and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, the Agency must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency.

EPA interprets Executive Order 13045 as applying only to those regulatory actions that are based on health or safety risks, such that the analysis required under section 5-501 of the Order has the potential to influence the regulation. This rule is not subject to Executive Order 13045 because it is not economically significant as defined in Executive Order 12866, and because the Agency does not have reason to believe the environmental health or safety risks addressed by this action present a disproportionate risk to children.

H. Executive Order 13211—Actions That Significantly Affect Energy Supply, Distribution, or Use

This rule is not a “significant energy action” as defined in Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001) because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy.

I. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (“NTTAA”), Public Law 104-113, section 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards such as materials specifications, test methods, sampling procedures, and business practices that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards.

This rule does not involve technical standards. Therefore, NTTAA does not apply.

J. Congressional Review Act

The Congressional Review Act (CRA), 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. Prior to publication of the final rule in the Federal Register, we will submit all necessary information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States. Under the CRA, a major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2). This rule will be effective upon publication in the Federal Register.

List of Subjects in 40 CFR Part 112

• Environmental protection
• Oil pollution
• Penalties
• Reporting and recordkeeping requirements

Dated: February 10, 2006.

Stephen L. Johnson,

Administrator.

For the reasons set forth in the preamble, title 40 CFR, chapter I, part 112 of the Code of Federal Regulations is amended as follows:

PART 112—OIL POLLUTION PREVENTION

1. The authority citation for part 112 continues to read as follows:

Authority: 33 U.S.C. 1251 et seq.; 33 U.S.C. 2720; E.O. 12777 (October 18, 1991), 3 CFR, 1991 Comp., p. 351.

2. Section 112.3 is amended by revising paragraphs (a), (b), and (c) to read as follows:

§ 112.3

Requirement to prepare and implement a Spill Prevention, Control, and Countermeasure Plan.

* * * * *

(a) If your onshore or offshore facility was in operation on or before August 16, 2002, you must maintain your Plan, but must amend it, if necessary to ensure compliance with this part, by October 31, 2007, and implement the Plan no later than October 31, 2007. If your onshore or offshore facility becomes operational after August 16, 2002, through October 31, 2007, and could reasonably be expected to have a discharge as described in § 112.1(b), you must prepare and implement a Plan on or before October 31, 2007.

(b) If you are the owner or operator of an onshore or offshore facility that becomes operational after October 31, 2007, and could reasonably be expected to have a discharge as described in § 112.1(b), you must prepare and implement a Plan before you begin operations.

(c) If you are the owner or operator of an onshore or offshore mobile facility, such as an onshore drilling or workover rig, barge mounted offshore drilling or workover rig, or portable fueling facility, you must prepare, implement, and maintain a facility Plan as required by this section. You must maintain your Plan, but must amend and implement it, if necessary to ensure compliance with this part, on or before October 31, 2007. If your onshore or offshore mobile facility becomes operational after October 31, 2007, and could reasonably be expected to have a discharge as described in § 112.1(b), you must prepare and implement a Plan before you begin operations. This provision does not require that you prepare a new Plan each time you move the facility to a new site. The Plan may be a general Plan. When you move the mobile or portable facility, you must locate and install it using the discharge prevention practices outlined in the Plan for the facility. The Plan is applicable only while the facility is in a fixed (non-transportation) operating mode.

Footnotes

1.  Comments and our response to them regarding the separate extension of the compliance dates for farms will be addressed in the rulemaking that addresses the substantive modifications that were proposed for the SPCC rule on December 12, 2005.

2.  This guidance is intended to assist regional inspectors in reviewing a facility's implementation of the SPCC rule. The document is designed to facilitate an understanding of the rule's applicability, to help clarify the role of the inspector in the review and evaluation of the performance-based SPCC requirements, and to provide a consistent national policy on several SPCC-related issues. The guidance is available on the Agency's Web site at http://www.epa.gov/​oilspill.
