Oil Pollution Prevention; Spill Prevention, Control, and Countermeasure Plan Requirements--Amendments

AGENCY: Environmental Protection Agency.

ACTION: Final rule.

SUMMARY: The Environmental Protection Agency (EPA or the Agency) is amending the Spill Prevention, Control, and Countermeasure (SPCC) Plan requirements by: first, providing the option for owners and operators of facilities that store 10,000 gallons of oil or less and meet other qualifying criteria to self-certify their SPCC Plans in lieu of review and certification by a Professional Engineer; second, providing an alternative to the general secondary containment requirement without requiring a determination of impracticability for facilities that have particular types of oil-filled equipment; third, defining and exempting particular vehicle fuel tanks and other on-board bulk oil storage containers used for motive power; and fourth, exempting mobile refuelers from the sized secondary containment requirements for bulk storage containers. The Agency also is removing and reserving the SPCC requirements for animal fats and vegetable oils that are specific to onshore oil production facilities, onshore oil drilling and workover facilities, and offshore oil drilling, production, or workover facilities. Finally, the Agency is extending the SPCC compliance dates for farms. These changes significantly reduce the burden imposed on the regulated community for complying with the SPCC requirements, while maintaining protection of human health and the environment. In a separate document in this Federal Register, the Agency is proposing to extend the compliance dates for all facilities.

DATES: This final rule is effective February 26, 2007.

  3. General Information

    The Environmental Protection Agency (EPA or the Agency) is amending the Spill Prevention, Control, and Countermeasure (SPCC) Plan requirements of the Oil Pollution Prevention regulation at 40 CFR part 112 to streamline the regulatory requirements for owners and operators of a subset of facilities by: (1) Providing an option to allow the owners or operators of facilities with an oil storage capacity of 10,000 gallons or less and who meet other qualifying criteria to self- certify their SPCC Plans in lieu of review and certification by a Professional Engineer; (2) allowing owners and operators of facilities that have particular types of oil-filled operational equipment to use an oil spill contingency plan along with an inspection or monitoring program as an alternative to secondary containment for qualified equipment without requiring a determination of impracticability; (3) providing an exemption for newly defined ``motive power containers''; and (4) exempting mobile refuelers from the specifically sized secondary containment requirements for bulk storage containers. In addition, the Agency is removing and reserving certain SPCC requirements for animal fats and vegetable oils; and is extending the compliance dates for farms. The purpose of this rulemaking is to provide streamlined, alternative approaches for compliance with oil spill prevention requirements for these entities, and to improve net welfare by reducing the costs of regulation and improving compliance, resulting in greater environmental protection.

  5. Statutory Authority and Delegation of Authority

    Section 311(j)(1)(C) of the Clean Water Act (CWA or the Act), 33 U.S.C. 1321(j)(1)(C), requires the President to issue regulations establishing procedures, methods, equipment, and other requirements to prevent discharges of oil from vessels and facilities and to contain such discharges. The President delegated the authority to regulate non- transportation-related onshore facilities to EPA in Executive Order 11548 (35 FR 11677, July 22, 1970), which has been replaced by Executive Order 12777 (56 FR 54757, October 22, 1991). A Memorandum of Understanding (MOU) between the U.S. Department of Transportation (DOT) and EPA (36 FR 24080, November 24, 1971) established the definitions of transportation-related and non-transportation-related facilities. A MOU among EPA, the U.S. Department of the Interior (DOI), and DOT, effective February 3, 1994, has re-delegated the responsibility to regulate certain offshore facilities from DOI to EPA.

  6. Background

    On July 17, 2002, EPA published a final rule amending the SPCC rule, formally known as the Oil Pollution Prevention regulation (40 CFR part 112), promulgated under the authority of section 311(j) of the CWA. (The SPCC rule was originally promulgated on December 11, 1973 (38 FR 34164).) This rule included revised requirements for SPCC Plans and for Facility Response Plans (FRPs). It also included new subparts outlining the requirements for various classes of oil; revised the applicability of the regulation; amended the requirements for completing SPCC Plans; and made other modifications (67 FR 47042). The revised rule became effective on August 16, 2002. After publication of this rule, several members of the regulated community filed legal challenges to certain aspects of the rule. Most of the issues raised in the litigation have been settled, following which EPA published clarifications in the Federal Register to several aspects of the revised rule (69 FR 29728, May 25, 2004).\1\ In addition, concerns were raised about the implementability of certain aspects of the 2002 rule.

    \1\ American Petroleum Institute v. Leavitt, No. 1:102CV02247 PLF and consolidated cases (D.D.C. filed Nov. 14, 2002). The remaining issue to be decided concerns the definition of ``navigable waters'' in Sec. 112.2.

    EPA has extended the dates for compliance with the 2002 rule by extending the dates for amending and implementing revised SPCC Plans in 40 CFR 112.3(a), (b), and (c), most recently by notice dated February 17, 2006 (71 FR 8462). Please see the Federal Register notice for further discussion on the compliance extensions. EPA took the most recent action in order to allow time to finalize the revisions in today's final rule and to provide the regulated community time to review and understand the material presented in the SPCC Guidance for Regional Inspectors, which was made available in December of 2005. The Agency also was concerned that the effects of the September 2005 hurricanes on many industry sectors might adversely impact their ability to meet the compliance dates if no extension was provided.

    October 31, 2007 is the current deadline for amending and implementing revised SPCC Plans for facilities (including mobile facilities) that were in operation on or before August 16, 2002. Facilities that came into operation after August 16, 2002 also must prepare and implement an SPCC Plan on or before October 31, 2007. As discussed in Section V.F of this preamble, today's final rule provides an additional extension of the compliance date for farms. Today's rule, which is effective February 26, 2007, does not modify the compliance dates for owners and operators of facilities other than farms. Elsewhere in today's Federal Register, EPA is proposing to extend the compliance dates for owners and operators of facilities until July 1, 2009 based on further SPCC regulatory revisions that EPA is considering, and that it expects to propose in 2007.

    On September 20, 2004, EPA published two Notices of Data Availability (NODAs). The first NODA solicited comments on submissions to EPA that suggested more focused requirements for owners and operators of facilities subject to the SPCC rule that handle oil below a certain threshold amount, referred to as ``certain facilities'' (69 FR 56182). Streamlined approaches for owners and operators of facilities with oil capacities below a certain threshold were discussed in the NODA-related documents. The second NODA solicited comments on whether alternate regulatory requirements would be appropriate for owners and operators of facilities with oil-filled and process equipment (69 FR 56184). EPA has reviewed the public comments and data submitted in response to the NODAs in developing today's final rule.

    Additionally, on December 2, 2005, EPA issued the SPCC Guidance for Regional Inspectors. This guidance document is intended to assist regional inspectors in reviewing implementation of the SPCC rule at a regulated facility. The guidance document is designed to facilitate an understanding of the rule's applicability, to help clarify the role of

    [[Page 77269]]

    the inspector in the review and evaluation of a facility owner or operator's compliance with the performance-based SPCC requirements, and to provide a consistent national policy on several SPCC-related issues. The guidance is available to owners and operators of facilities that may be subject to the requirements of the SPCC rule and to the general public on the Agency's Web site at http://www.epa.gov/oilspill. This

    guidance document is a living document and will be revised, as necessary, to reflect any relevant future regulatory amendments, including today's action.

    Based on the comments received on the NODAs, as well as other information received, EPA proposed to amend the SPCC rule to address a number of issues raised, including those pertaining to qualified facilities, qualified oil-filled operational equipment, motive power containers, airport mobile refuelers, animal fats and vegetable oils, and the compliance date for farms. (See 70 FR 73524, December 12, 2005.) EPA discusses each of these issues in Section V of this preamble. The preamble generally discusses the comments received on the proposal, EPA's response, and any modifications made to the proposal. For a more detailed discussion of the comments received and EPA's response, see ``Summary and Response to Comments,'' which is included in the docket for today's final rule.

    The scope of today's final rule was intended to address only certain targeted areas of the SPCC requirements, and a number of issues and concerns raised by the regulated community. As highlighted in the EPA Regulatory Agenda and the 2005 OMB report on ``Regulatory Reform of the U.S. Manufacturing Sector,'' EPA is considering further amendments to address other areas where regulatory reform may be appropriate. For these additional areas, the Agency expects to issue a proposed rule in 2007. Areas where regulatory reform may be appropriate include, and are not limited to, oil and natural gas exploration and production, farms, and Tier I facilities. EPA, in conjunction with DOE, has been conducting an energy impact analysis of the SPCC requirements, and, to the extent that the analysis is available, will consider it to inform the Agency's 2007 rulemaking.

    Because it is highly unlikely that the Agency will be able to promulgate such regulatory amendments before the current October 31, 2007 compliance date for SPCC becomes effective, EPA believes it is appropriate to provide an extension of the compliance date. Such an extension has been proposed elsewhere in today's Federal Register.

    The Agency is not in a position, at this time, to indicate all the areas for possible regulatory reform that may be addressed as part of the 2007 SPCC proposal. Nevertheless, the Agency recognizes that owners and operators of facilities need time to determine which changes may be made to the rules that may impact the requirements they are subject to in order to determine when they need to comply with the new requirements.

    This approach would allow those potentially affected in the regulated community an opportunity to make changes to their facilities and to their SPCC Plans necessary to comply with the revised requirements, rather than with the existing requirements. Regarding modifications of the SPCC regulations, EPA is proposing in a separate notice in today's Federal Register to extend the deadlines for compliance to July 1, 2009.

  7. Today's Action

    1. Qualified Facilities

      1. Overview of the Qualified Facilities Proposal

      On December 12, 2005 (70 FR 73524), EPA proposed to amend the SPCC rule to provide an option to allow the owner or operator of a facility that meets the qualifying criteria (hereafter referred to as a ``qualified facility'') to self-certify the facility's SPCC Plan in lieu of review and certification by a licensed Professional Engineer (PE). EPA proposed to amend Sec. 112.3 to describe the SPCC eligibility criteria that a regulated facility must meet in order to be considered a qualified facility.

      As proposed, the eligibility criteria for a qualified facility would be a facility subject to the SPCC rule that (1) has an aggregate oil storage capacity of 10,000 gallons or less; and (2) had no discharges as described in Sec. 112.1(b) during the ten years prior to self-certification. Self-certified Plans could not include ``environmentally equivalent'' alternatives to required Plan elements as provided in Sec. 112.7(a)(2) or contingency planning in lieu of secondary containment as provided in Sec. 112.7(d) on the basis of ``impracticability.'' However, the proposal included specified ``environmentally equivalent'' measures with respect to security and integrity testing that would be available to facility owners and operators that choose to self-certify. Self-certification would be optional for owners and operators of facilities meeting the eligibility criteria, so that those owners and operators of qualified facilities that found the existing rules more cost-effective in achieving compliance with the SPCC requirements, would continue to have the option of complying with the streamlined approach or could choose to comply with the existing SPCC requirements (including the PE certification) to take advantage of the flexibility offered by PE- certified impracticability determinations and environmentally equivalent measures.

      In general, the Agency agrees with the commenters who supported the qualified facilities proposal for self-certification and believe that this revision will relieve regulatory burden on small oil storage facilities. As one commenter noted, self-certification should result in greater compliance rates across the board. Therefore, today's rule finalizes the proposed provision with a few modifications.

      As described in the preamble to the proposed rule, EPA also considered, but did not propose, a multi-tiered structure option based on an analysis prepared for the U.S. Small Business Administration's (SB

    2. Office of Advocacy that included a tiered system for facilities that have total oil storage capacities between 1,321 and 5,000 gallons, between 5,001 and 10,000 gallons, and greater than 10,000 gallons. Under this option, Tier I facilities (1,321 to 5,000 gallons oil storage capacity) would not need a written SPCC Plan (and therefore no PE certification), but would adhere to all other SPCC requirements. Tier II facilities (5,001 to 10,000 gallons oil storage capacity) would be required to have a written SPCC Plan, but no PE certification requirement. Tier III facilities (greater than 10,000 gallons oil storage capacity) would be required to have a written SPCC Plan, certified by a PE. A significant number of commenters on the proposed rule supported a multi-tiered approach.

      The Agency continues to believe that a facility owner or operator cannot effectively implement an oil spill prevention program, or any other program (business or otherwise), without documentation of that program's action items. As a matter of practice, it would be extremely difficult for a facility owner or operator to be able to follow the regulatory requirements and to comply with all the recordkeeping components without the documentation that is the Plan itself. The Plan also serves as an important communication and training tool for both management and oil-handling personnel at the facility. The sole action of having to document compliance with all of the requirements can assist in

      [[Page 77270]]

      uncovering flaws in the program's implementation, and may serve as a tool to correct them. Additionally, the documentation of compliance with the rule's requirements in a written Plan serves as a facility- specific oil spill response and prevention planning exercise which is designed to improve oil spill prevention. Nevertheless, the Agency understands the concerns, particularly of owners and operators of facilities with a smaller oil storage capacity and likely more limited resources, of the potential effort needed to develop a complicated Plan. Thus, the Agency has been exploring the possibility of developing a further simplified Plan for facilities that handle between 1,320 and 5,000 gallons of oil. However, because the Agency is considering removing or changing some of the regulatory requirements and developing a standardized form/checklist for ease of implementation, the Agency chose not to finalize this option without taking further comment. Therefore, although EPA is not adopting a multi-tiered approach in today's final rule, the Agency intends to propose a simplified approach for facilities that handle between 1,320 and 5,000 gallons of oil within the near future. In that proposal, the Agency expects to discuss the implementation of the SPCC rule for these facilities.

      The preamble to the proposed rule also described an approach whereby the Agency would require owners and operators of qualified facilities to make a one-time notification to EPA if they have been in operation or subject to the SPCC requirements for a period less than ten years from the time of Plan certification, and therefore could not show a ten-year clean spill history as a qualifier. The comments generally opposed a notification requirement, arguing that it would impose additional burden with no clear benefit for the regulated community. EPA is not adopting this one-time notification requirement, because the Agency does not believe it would offer any further environmental protection. The additional burden of a notification requirement was not considered necessary and would be contrary to the intent of today's rule. 2. Summary of This Final Rule for Qualified Facilities

      Today's rule finalizes the proposed option with modifications to the reportable discharge history criterion and to the self- certification limitations for qualified facilities. The final rule also places the alternative self-certification provisions in Sec. 112.6, rather than in Sec. 112.3(g) as proposed. A facility owner or operator may qualify to prepare a Plan that meets the alternative requirements in Sec. 112.6 of today's final rule, in lieu of a Plan prepared in accordance with the general requirements contained in Sec. 112.7 and the applicable requirements in subparts B and C of the rule. Finally, today's action allows a qualified facility owner or operator to use environmentally equivalent measures or an impracticability determination provided they are certified by a PE.

      To qualify for this option, a facility must meet the following eligibility criteria: the facility had no single discharge as described in Sec. 112.1(b) exceeding 1,000 U.S. gallons or no two discharges as described in Sec. 112.1(b) each exceeding 42 U.S. gallons within any twelve month period in the three years prior to the SPCC Plan certification date, or since becoming subject to 40 CFR part 112 if the facility has been in operation for less than three years, and the facility has 10,000 gallons or less in aggregate aboveground oil storage capacity. Discharges as described in Sec. 112.1(b) that are the result of natural disasters, acts of war, or terrorism will not disqualify a facility owner or operator from using the self- certification option.

      An owner or operator of a qualified facility may prepare, self- certify and implement an SPCC Plan that complies with all of the applicable requirements of the rule in accordance with Sec. 112.6 of today's final rule. No PE certification is required for qualified facilities' Plans. A qualified facility owner or operator also may choose to prepare a Plan in accordance with the general Plan requirements in Sec. 112.7 and applicable requirements in subparts B and C, including having the Plan certified by a Professional Engineer as required under Sec. 112.3(d). The qualified facility approach in today's final rule is optional; owners or operators of facilities that qualify may choose not to exercise this option.

      In proposing this option for facilities handling smaller amounts of oil, the Agency sought to focus on those smaller operations that may be concerned about the impact of utilizing a PE on their limited budget. Some of the current noncompliance with the SPCC regulation may be attributed to those concerns. The Agency believes that providing a simpler, less costly option for owners and operators of these smaller, less complex facilities will improve the overall compliance for the SPCC regulation, ultimately resulting in greater environmental protection. 3. Eligibility Criteria a. Total Facility Oil Storage Capacity Threshold

      EPA proposed to limit the maximum aggregate oil storage capacity at a qualified facility to 10,000 gallons or less. EPA considered many different factors before selecting this maximum storage capacity. As explained in the preamble to the proposal (70 FR 73529), EPA has established 10,000 gallons as a threshold in several other rules relating to oil discharges. The National Oil and Hazardous Substances Pollution Contingency Plan size classes define an oil discharge to inland waters exceeding 10,000 gallons as a major discharge. An oil discharge of 10,000 gallons or more to waters of the U.S. and adjoining shorelines that could reasonably be expected to cause substantial harm to the environment also is one of the factors used in identifying facilities whose owners and operators must prepare and submit a Facility Response Plan (see 40 CFR 112.20(f)(1)(D). A number of State regulations also differentiate regulatory requirements based on a facility's total storage capacity, with some States specifying a 10,000-gallon threshold (e.g., Maryland, Minnesota, Oregon, New York, Wisconsin). Finally, 10,000 gallons is a common storage container size.

      More commenters supported than opposed the proposed threshold eligibility criterion of total oil storage capacity of 10,000 gallons or less, while others offered alternative thresholds. Many commenters supported the idea of establishing tiers for qualified facilities. (As noted earlier, the Agency intends to propose a more streamlined approach for owners and operators of facilities with a total oil storage capacity of 5,000 gallons or less.) Many supporters believed that the proposed 10,000-gallon threshold would reduce the financial burden on owners and operators of small facilities. Among commenters that opposed the threshold, at least one stated that the proposed 10,000-gallon threshold did not provide enough regulatory relief to owners and operators of small facilities, but others noted that smaller storage sizes do not necessarily correlate with lower spill risk.

      Facilities handling smaller amounts of oil are typically simpler in layout and operation. Most facilities with an oil storage capacity of 10,000 gallons or less are in industrial sectors that are end-consumers of oil (i.e. farms, real estate, rental and leasing, retail trade, construction [see the Regulatory Impact Analysis for this action, found in the docket for today's final rule]). These

      [[Page 77271]]

      facilities are commonly not in an oil production or distribution business and tend to use oil on-site for heating purposes, or to fuel emergency power generators or heavy machinery. The configuration of the oil-related equipment tends to be relatively standard and simple. Oil is commonly stored in a few bulk storage containers which are often bought off-the-shelf from a tank manufacturer or installer (e.g., standard UL-142 tanks) and connected with few short lengths of piping in a standard configuration that changes relatively little from one facility to another.

      Additionally, these facilities typically do not have significant transfers of oil because they do not further distribute the oil. A survey conducted by EPA of oil storage facilities (1995 SPCC Survey of Oil Storage Facilities) found that the larger the storage capacity at a facility, the greater the likelihood of larger spills, more spills, and more cleanup costs annually. Our regression analyses of the 1995 survey data (see ``Analysis of the Relationship between Facility Characteristics and Oil Spill Risk,'' found in today's docket) confirmed similar linkages for facilities with a greater number of tanks and larger annual throughput. These analyses were performed because storage capacity, number of tanks, and throughput were identified as important individual factors in explaining the total annual spill volume, number of spills, and cleanup costs. Thus, these factors were used together in a multivariate regression model to ensure that these three variables continue to be statistically significant variables when assessing whether there is potential bias (i.e., an overstatement of the importance of the variable in explaining the variation in the dependent variable). After performing these analyses, storage capacity and number of tanks were found to be statistically significant in relation to all three measures of spill risk (i.e., total number, volume, and cleanup costs of oil spills). The Agency believes simple oil storage configuration, in conjunction with the smaller quantities of oil handled at qualified facilities, makes self- certification an appropriate alternative. Therefore, the Agency has decided to maintain the maximum aggregate oil storage capacity for qualified facilities at 10,000 gallons as proposed.

      The development of streamlined requirements for owners and operators of those facilities with a smaller size or storage volume is not new; industry standards, engineering codes and practices, State regulations, local fire codes and local ordinances often recognize the differences between sizes and complexity of their target facilities and/or equipment and as a result incorporate simplified requirements. The Agency believes that today's action provides an alternative compliance option for owners and operators of facilities handling smaller amounts of oil that will ultimately result in increased environmental protection by making it easier and less burdensome to comply.

      EPA recognizes that an oil discharge of less than 10,000 gallons can be harmful (see 40 CFR part 110, where the Agency defines what constitutes a discharge of oil in quantities that may be harmful). Nevertheless, EPA believes that it is reasonable to allow owners and operators of facilities with a capacity of no more than 10,000 gallons the option to prepare and implement SPCC Plans without the involvement of a PE (except in those cases where environmental equivalence or an impracticability determination is requested by an owner or operator and that the owner or operator chooses to have a PE certify part or all of the facility SPCC Plan). Therefore, the Agency is adopting in today's rule a threshold capacity of 10,000 gallons as a criterion for those facilities that are qualified for self-certification.

      Some commenters argued that the 10,000-gallon threshold would still preclude owners and operators of smaller facilities from taking advantage of the self-certification alternative. For example, a facility with two 5,000-gallon storage containers and a few totes just exceeds the 10,000-gallon threshold. Commenters argued that these kinds of facilities have low volumes of oil and simple operations, and that perhaps a slightly higher threshold would be more appropriate. The Agency recognizes that regardless of the threshold quantity selected, there are likely to be facilities just above that threshold that will be excluded. To the extent that facility owners or operators want to take advantage of the streamlined approach, they always have the option of reducing the storage capacity of oil at their facility by either removing containers from the facility inventory, or permanently closing containers in accordance with Sec. 112.2.

      Other commenters suggested higher threshold quantities, generally based upon the quantities of oil used or stored in their particular industry sector. EPA does not agree that this provides a rational basis for raising the threshold limit for qualified facilities. Higher thresholds would potentially allow owners and operators of facilities (in some cases unmanned) with more complex operations or more complex oil system configurations, designs and layouts, and with the potential for an increased number of transfers, the option of foregoing the services of a PE. Thus, self-certification for owners and operators of more complex facilities would not be commensurate with their potential spill risks.

      By limiting the self-certification option to owners and operators of facilities with a maximum aggregate oil storage capacity of 10,000 gallons, the Agency believes that an owner or operator of a qualified facility should be able to self-certify compliance the facility's SPCC Plan, and that offering this simpler and streamlined alternative will result in greater environmental protection by improving compliance with the SPCC rule. Owners and operators of facilities handling smaller amounts of oil would still be required to comply with the SPCC requirements and to prevent and prepare to respond to oil discharges to navigable waters and adjoining shorelines, but they would be able to do so in a less costly manner. We believe this alternative certification provision will prove to be an incentive for compliance. b. Reportable Discharge History

      Clean Water Act section 311(b)(3) prohibits ``the discharge of oil * * * into or upon the navigable waters of the United States, the adjoining shorelines, or into or upon the waters of the contiguous zone'' or in connection with specified activities in waters ``in such quantities as may be harmful * * *.'' Section 311(b)(4) requires regulations to define the quantities of oil, ``the discharge of which may be harmful to the public health or welfare or the environment of the United States, * * *.'' 33 U.S.C. 1321(b)(3), (4). In part 110, EPA defines a ``discharge of oil in such quantities that may be harmful'' as a discharge of oil that violates applicable water quality standards; a discharge of oil that causes a film or sheen upon the surface of the water or on adjoining shorelines; or a discharge of oil that causes a sludge or emulsion to be deposited beneath the surface of the water or adjoining shorelines (40 CFR 110.3). The Agency refers to such discharges as reportable discharges or as ``a discharge as described in Sec. 112.1(b)'' of the rule. Any person in charge of a facility must report any such discharge of oil to waters of the United States, adjoining shorelines, the contiguous zone or in connection with specified activities in waters from the facility to the National Response Center (NRC) at 1-800-424-8802 immediately. While EPA recognizes that past discharge

      [[Page 77272]]

      history does not necessarily translate into a predictor of future performance, the Agency believes that discharge history is a reasonable indicator of a facility owner or operator's ability to develop an SPCC Plan for his smaller oil storage capacity facility without the involvement of a PE.

      EPA proposed that a qualified facility subject to the SPCC requirements must have no reportable oil discharges as described in Sec. 112.1(b) during the ten years prior to self-certification or since becoming subject to the SPCC requirements, whichever time period is less. The Agency proposed using a facility's reportable discharge history as a reasonable indicator of the effective implementation of an SPCC Plan based on an established record of good oil spill prevention. The reportable discharge history criterion was intended to limit the option of self-certification to owners and operators of those facilities that had demonstrated an effective implementation of spill prevention measures in the past.

      The commenters who supported the proposed reportable discharge requirement agree that it is important for a facility to have a clean spill history. However, a significant number of commenters argued against the proposed reportable discharge history criterion as an appropriate criterion, and that the small storage capacity alone should be sufficient to allow self-certification. One reason is that some reportable discharges are not the facility owner or operator's fault, but caused by outside sources. For example, a number of commenters pointed to the recent hurricanes in the Gulf Coast states that led to oil discharges that were not within the control of the facility owner or operator. A further reason is that facilities that have a clean discharge history might not always remain spill-free. As for the proposed ten-year period, one commenter stated that facility owners and operators are only required to keep records for SPCC Plans for three years; most owners and operators keep them for five years. Another commenter stated that a discharge history of ten years would almost be impossible to prove. Another commenter believed that the qualification for a qualified facility should not be based on the ten-year discharge history, but should be based on the discharge history under the current operator. A few commenters believed that risk of discharge should determine self-certification. Additionally, many commenters recommended alternative discharge history timeframes in place of the ten-year timeframe EPA proposed. Half of the commenters believed that three years should be the time frame for the reportable discharge history since the SPCC record-keeping requirement for facility owners and operators is three years. Two commenters mentioned that if a discharge occurs and the Regional Administrator (RA) responds, and after review of the SPCC Plan the RA does not require an amendment in the Plan, then the discharge should not count against the facility owner or operator when determining its compliance with a spill-history criterion.

      After consideration of the comments received, EPA is finalizing the reportable discharge criterion for qualified facilities but for three years, rather than ten years. The Agency agrees with commenters that a ten-year spill history is unreasonable, particularly since the facility owner or operator is only required to keep records for three years. In addition, EPA is modifying the types of discharges that must be considered for this criterion. The final rule provides that for the three years prior to the SPCC Plan certification date, or since becoming subject to 40 CFR part 112 if the facility has been in operation for less than three years, the owner or operator of a facility must certify that the facility has (1) had no single discharge as described in Sec. 112.1(b) exceeding 1,000 U.S. gallons or (2) had no two discharges as described in Sec. 112.1(b) each exceeding 42 U.S. gallons within any twelve month period. When determining spill history, the gallon amount specified in the criterion (either 1,000 or 42) refers to the amount of oil that actually reaches waters of the United States, adjoining shorelines, the contiguous zone or in connection with specified activities in waters and not the total amount of oil spilled. For example, a facility only experiencing one discharge over the past ten years in which 1,500 gallons of oil discharged onto the ground but only 20 gallons reached waters of the United States (causing a sheen and reportable to the NRC) would meet the reportable discharge history criterion. However, a facility having 1,500 gallon discharge to waters of the United States would not meet the reportable discharge history criterion.

      In the preamble to the proposed rule, EPA requested comment on how extreme events such as natural disasters, acts of war or terrorism, sabotage or other calamities might potentially affect the discharge history criterion for qualified facilities. Many commenters stated that it would not be appropriate to include these events in the discharge history criterion. The Agency agrees that those reportable discharges caused by external factors beyond the control of the facility owner or operator such as natural disasters, acts of war, or terrorism should not disqualify owners and operators of otherwise qualified facilities from taking advantage of the self-certification option. Therefore, we have excluded those events from consideration in the reportable discharge criterion in today's final rule. The Agency did not include sabotage/vandalism in the final list of reportable discharge history extreme events because these are not necessarily beyond the control or planning ability of the facility owner or operator. Only those discharges as described in Sec. 112.1(b) that are the result of natural disasters, acts of war, or terrorism will not disqualify any owner or operator of an otherwise qualified facility from using the self-certification option.

      The discharge criterion finalized in today's rule is similar to the provision in Sec. 112.4(a) for discharges that must be reported to the EPA Regional Administrator (RA). A discharge that must be reported to the RA pursuant to Sec. 112.4(a) may result from improper Plan implementation, rather than from a deficiency in the Plan itself, which would likely not cause the RA to require the facility owner or operator to amend its Plan. Therefore, the EPA does not agree with the commenters that suggested excluding those discharges as described in Sec. 112.1(b) from the eligibility criterion that have been investigated by the RA with no subsequent requirement for a Plan amendment.

      The determination of eligibility based on reportable discharge history is made at the time the SPCC Plan is certified--i.e., when the SPCC Plan is amended to comply with the SPCC rule revisions in today's final rule and those promulgated in July 2002. Once the compliance date extension ends, Plans must be amended, certified and implemented. Any discharges to navigable waters and adjoining shorelines that occur from a qualified facility after the SPCC Plan has been certified do not impact the eligibility of an owner or operator of the qualified facility to take advantage of the self-certification option. The facility does not lose eligibility status as a result of a discharge as described in Sec. 112.1(b), unless the RA requires an amendment to the SPCC Plan in accordance with Sec. 112.4(d) and specifically requires PE-certification. If an owner or operator cannot certify that the facility meets the eligibility criterion at the initial date of Plan certification, but can later demonstrate a clean spill history of three years, as well as compliance with any remedial actions required by the RA

      [[Page 77273]]

      following a spill, then a technical amendment to the Plan can be self- certified and the Plan can be revised to allow for qualified status. 4. Requirements for Qualified Facilities

      In today's rule, the Agency is creating a new section, Sec. 112.6, with requirements specific for qualified facilities whose owners and operators choose to self-certify their Plans. Owners and operators of qualified facilities with an aggregate aboveground oil storage capacity of 10,000 gallons of oil or less may choose to comply with the requirements in Sec. 112.6 by completing and implementing a self- certified SPCC Plan. A qualified facility's Plan, whether certified by a PE or self-certified, must comply with all of the applicable requirements of Sec. 112.7 and subparts B and C of the rule. We note, however, that a facility's SPCC Plan does not need to conform to any particular format. There is flexibility with respect to how a facility owner or operator chooses to maintain the documentation comprising the facility's Plan, just as there is flexibility with respect to how the owner or operator chooses to carry out the elements of the Plan. a. Self-Certification of Plan and Plan Amendment

      The commenters who supported self-certification for owners and operators of qualified facilities believed that it would relieve burden on the owners and operators. The commenters who opposed self- certification did so for four main reasons. First, some commenters believe that the preparation of the SPCC Plan requires scientific, engineering, and professional judgment skills that are unique to engineers. Second, some commenters believe owners and operators of small facilities often cannot afford the cost of responding to a spill, and it is important that the SPCC Plan is prepared carefully and thoroughly by a PE. Third, some commenters believe that not having a PE involved would adversely affect public health, safety, and welfare. Fourth, some commenters believe that the proposal would allow non- engineers to perform a function that is only allowed by engineers under the National Council of Examiners for Engineering and Surveying, a Model Law adopted by the majority of States.

      The self-certification option is designed for owners and operators of those facilities that store smaller amounts of oil. These smaller amounts of oil generally translate to facilities with simpler, pre- engineered installations, such as restaurants, office buildings, family farms, automotive repair shops, and rural electrical substations. EPA believes that a differentiated option for users of smaller amounts of oil has merit as other official bodies, such as standards setting organizations have provided differentiations in their standards for smaller users of oil. For example, the National Fire Protection Association (NFPA) provides differentiated requirements based on type of facility and size of tanks. Specifically, NFPA 30 (Flammable and Combustible Liquids Code, 2000 Edition) applies to tanks that exceed 3,000 liters (793 gallons) and does not apply to facilities storing flammable and combustible liquids as covered by NFPA 395, Standard for the Storage of Flammable and Combustible Liquids at Farms and Isolated Sites. The Agency believes that the relative simplicity of operations at facilities using smaller amounts of oil has served as a basis for other official bodies to develop requirements that are simpler in scope.

      To this end, the Agency is amending the certification language so that it clearly states that the owner or operator of the facility is the certifying official for those who choose the option to self-certify the Plan for qualified facilities. The Agency also intends to develop materials to assist these owners or operators in developing SPCC Plans. It should also be remembered that while owners and operators of these facilities may choose not to have their SPCC Plans certified by a PE, they will still be required to comply with all of the SPCC requirements and to develop and implement a spill prevention program in accordance with good engineering practices, and they may do so by following regulatory guidance, industry recommended practices and standard design and operation protocols. Finally, to the extent that a State has adopted a law, such as one based on the National Council of Examiners for Engineering and Surveying, that requires that a PE to perform certain functions, including certifying Plans, nothing in today's rule affects whether a facility owner or operator would be required to utilize a PE to meet the state or local requirements since today's rule does not pre-empt any State or local requirements.

      The Agency believes providing the added flexibility of self- certification for the smaller oil handlers/simpler operations will yield an increase in overall compliance for this segment of the regulated community, which will result in improved compliance with the rule and as a result, improve overall spill prevention and environmental protection. However, owners or operators of some qualified facilities with complicated operations may nonetheless find that having a PE-certified Plan offers a more cost-effective method of achieving compliance than the proposed option. Therefore, a qualified facility owner or operator could choose to follow the existing SPCC requirements (including the PE certification).

      The Agency also proposed and is finalizing today that an owner or operator of a qualified facility may self-certify technical amendments to the Plan, including modification of site diagrams, and that owners and operators of facilities with PE-certified Plans that qualify for self-certification can choose to self-certify future technical amendments rather than hire a PE to certify the technical amendment. Owners and operators of facilities that are not eligible to self- certify are required to have a PE certify such modifications. In all cases, any technical amendment in an SPCC Plan must be certified in writing. As described in the preamble to the proposed rule, the Agency notes that under the existing SPCC regulations, the RA, after reviewing the facility's Plan, has the authority in Sec. 112.4 to require an owner or operator of a facility that has had a discharge as described in Sec. 112.1(b) or that poses an imminent danger of a discharge as described in Sec. 112.1(b), to amend its SPCC Plan, including requiring PE certification in accordance with Sec. 112.3(d). b. Elements of Self-Certification and Plan Amendments for Owners and Operators of Qualified Facilities

      The finalized requirements for owners and operators of qualified facilities are similar to those in the proposed qualified facilities option in the proposed rule. An owner or operator of a qualified facility may choose to comply with the requirements in Sec. 112.6 by completing and implementing a self-certified SPCC Plan in lieu of having a PE certified Plan. The SPCC Plan must comply with all of the applicable requirements of Sec. 112.7 and subparts B and C of the rule.

      Owners and operators that choose to self-certify their Plans must certify that they are familiar with the requirements of the SPCC rule; they have visited and examined the facility; the Plan has been prepared in accordance with accepted and sound industry practices and standards; procedures for required inspections and testing have been established; the Plan is being fully implemented; the facility meets the qualification criteria set forth under Sec. 112.3(g); the Plan does not include any

      [[Page 77274]]

      environmental equivalence measures as described in Sec. 112.7(a)(2) or determinations of impracticability under Sec. 112.7(d) unless each alternative method and/or determination has been reviewed and certified by a PE in accordance with Sec. 112.6(d); and the Plan and the individual(s) responsible for implementing the Plan have the full approval of management and the facility owner or operator has committed the necessary resources to fully implement the Plan.

      The qualified facility self-certification approach is optional. Under today's final rule, an owner or operator of a qualified facility may choose to prepare and implement a PE-certified SPCC Plan to comply with the requirements under 40 CFR part 112. c. Environmental Equivalence and Impracticability Determinations

      Under Sec. 112.7, all facility owners and operators have the flexibility to deviate from specific rule provisions if the Plan states the reason for nonconformance and if equivalent environmental protection is provided by some other means of spill prevention, control, or countermeasure. These ``environmentally equivalent'' measures must be described in the SPCC Plan, including how the equivalent environmental protection will be achieved based on good engineering practice. Allowance for ``environmentally equivalent''' deviations is provided in Sec. 112.7(a)(2), and the deviations are available only for the specific requirements listed in Sec. 112.7(a)(2), such as fencing and other security measures, evaluation of the potential for catastrophic tank failure due to brittle fracture, integrity testing, and overfill prevention. Environmental equivalence is not available for secondary containment or the administrative or recordkeeping requirements of the SPCC rule. As part of the SPCC Plan, any environmentally equivalent measures are required to be certified by a PE and the owner or operator, and the PE is required to consider industry standards in the development of the Plan. Thus, when a PE certifies a Plan that includes any environmentally equivalent protection measure, the PE is certifying that these alternative measures are consistent with relevant industry standards.

      The SPCC rule also provides flexibility for owners or operators who determine that the general secondary containment requirements in Sec. 112.7(c) or any of the applicable additional requirements for secondary containment in subparts B and C are impracticable. Where impracticability is demonstrated, Sec. 112.7(d) allows facility owners and operators the flexibility to instead develop a contingency plan and comply with additional requirements. The SPCC Plan must explain why secondary containment measures are not practicable. Section 112.7(d) requires that, when containment for bulk storage containers is deemed impracticable, the owner or operator must conduct both periodic integrity testing of the containers and periodic integrity and leak testing of the valves and piping. The owner or operator also must provide an oil spill contingency plan that follows the provisions of 40 CFR part 109 (Criteria for State, Local and Regional Oil Removal Contingency Plans), and a written commitment of manpower, equipment, and materials required to expeditiously control and remove any quantity of oil discharged that may be harmful as described in 40 CFR part 110. A PE must certify any determinations that secondary containment is impracticable, as well as the additional measures implemented in lieu of secondary containment.

      Because of the expertise that a PE has in evaluating whether particular measures provide equivalent environmental protection and in knowing how to effectively implement such measures, EPA believes that the flexibility in these performance-based provisions is best suited to SPCC Plans that are reviewed and certified by a PE. The same expertise is necessary in determining whether the required secondary containment is impracticable.

      EPA proposed that when a Plan is self-certified, the owner or operator would not be able to use environmentally equivalent measures or to make impracticability determinations with respect to secondary containment. Instead, EPA proposed specific alternative measures for compliance with security and integrity testing requirements at qualified facilities that self-certify. The commenters who supported this approach indicated that it added a safety factor into the self- certification. Most commenters opposed this approach because impracticability determinations and environmental equivalence were originally created to relieve burden, and owners and operators of small facilities still need the flexibility these mechanisms provide. Some commenters believed that the agricultural industry would be negatively affected because the environmental equivalence and impracticability provisions are an important element to reduce the burden on owners and operators of these facilities due to topography and operations. As for the proposed specific alternative to environmentally equivalent measures for security, one commenter supported this proposal.

      With respect to integrity testing, the Agency proposed to allow self-certifying owners and operators of qualified facilities to perform integrity testing by relying on industry standards for the integrity testing requirements as an alternative to the existing bulk storage containing integrity testing requirements. All but one commenter supported the proposal. One commenter supported it, but also wanted visual inspection of individual shop-fabricated tanks up to 10,000 gallons. Another commenter agreed, but believed that the expense of the Steel Tank Institute's (STI) Tank Inspection Standard, SP001 (July 2005), was high and the STI standard and accompanying checklists are not applicable to small facilities. A hybrid approach also was suggested whereby owners and operators of qualified facilities would be allowed to use the self-certification option, and, in the event that an environmental equivalency or impracticability determination is needed, the owner or operator must consult a PE for just that aspect of their program, rather than requiring a full PE review and approval of the entire Plan.

      The Agency continues to believe that the flexibility afforded by the environmental equivalence or impracticability determinations should be available only to owners and operators of facilities having those elements reviewed and certified by a PE. At the same time, the Agency recognizes that by restricting these options for owners and operators of qualified facilities, the alternative of self-certification may not be as attractive for some owners or operators because they will lose the added flexibility of further tailoring the SPCC requirements to their facility's characteristics. The Agency agrees with commenters that under the proposed rule, there would likely be certain circumstances where, because of cost considerations, a facility owner or operator would not choose to self-certify because it would be more cost effective for a PE to prepare an SPCC Plan that utilizes environmentally equivalent measures or impracticability determinations.

      In today's final rule, the Agency therefore is adopting a hybrid approach. This approach finalizes the alternatives for addressing security measures and integrity testing and also allows owners or operators of self-certified facilities to include environmentally equivalent measures with respect to requirements other than facility security and integrity testing, as well as to make

      [[Page 77275]]

      impracticability determinations, provided they have a PE certify these environmentally equivalent measures or impracticability determinations. Because qualified facilities typically have less complex operations and petroleum system configurations and storage capacities than other facilities subject to SPCC requirements, EPA believes that the alternative requirements for facility security and bulk storage container integrity testing finalized today are appropriate for self- certification. However, today's rule does not preclude a qualified facility from choosing to have a PE certify the integrity testing and/ or security measures in the facility's Plan as environmentally equivalent measures. For example, where there are no industry standards to guide integrity testing at a qualified facility, the alternative integrity testing option in Sec. 112.6(c)(4)(ii) is not available. However, the facility owner/operator is allowed to have a PE certify an integrity testing protocol in the Plan that is environmentally equivalent to the applicable requirements in subpart B or C. The Agency believes that this ``hybrid'' approach will further expand the flexibility offered by the self-certification compliance option to owners and operators of qualified facilities without compromising proper environmental protection.

      Similarly, EPA is adopting a hybrid approach to certification of technical amendments to a qualified facility's SPCC Plan in Sec. 112.5. PE-certified sections of a qualified facility's ``hybrid'' SPCC Plan require PE certification of any technical amendments to that portion of the Plan. Technical amendments to the non-PE certified sections of a qualified facility's ``hybrid'' Plan can be certified by the owner or operator.

    3. Qualified Oil-Filled Operational Equipment

      The definition of bulk storage container in Sec. 112.2 specifically excludes oil-filled electrical, operating, and manufacturing equipment (``oil-filled equipment''). Therefore, oil- filled equipment is not subject to the bulk storage container requirements in Sec. Sec. 112.8(c), 112.9(c), and 112.12(c). However, oil-filled equipment must meet the general requirements of Sec. 112.7, including the general secondary containment requirements of Sec. 112.7(c). The general secondary containment requirements are intended to address the most likely oil discharge from oil-filled equipment. Although oil-filled equipment differs from bulk storage containers in several ways, the oil storage capacity of oil-filled equipment still counts towards the aggregate oil storage capacity of the facility.

      EPA proposed to amend the SPCC rule to provide a definition of oil- filled operational equipment and an optional alternative to the general secondary containment requirements for oil-filled operational equipment at a facility that meets the qualifying criterion (hereafter referred to as ``qualified oil-filled operational equipment''). These amendments are being finalized in today's rule. The rule allows owners and operators of facilities with eligible oil-filled operational equipment as defined in Sec. 112.2 the option to prepare an oil spill contingency plan and a written commitment of manpower, equipment, and materials to expeditiously control and remove any oil discharged that may be harmful without having to make an individual impracticability determination as required in Sec. 112.7(d). If an owner or operator takes this option, he or she is also required to establish and document an inspection or monitoring program for this qualified oil-filled operational equipment to detect equipment failure and/or a discharge in lieu of providing secondary containment.

      New provisions in Sec. 112.7(k) define the criterion that facilities must meet in order to be considered eligible for the ``qualified oil-filled operational equipment'' option. Eligibility of a facility with oil-filled operational equipment is determined by considering the reportable discharge history from only oil-filled operational equipment at the facility; the Agency is adopting the same reportable discharge history criterion that it adopted for qualified facilities, as discussed in Section V.A.3.b above. That is, the qualified oil-filled operational equipment criterion specifically requires that the facility did not discharge more than 1,000 U.S. gallons in a single discharge as described in Sec. 112.1(b) or discharge more than 42 U.S. gallons in each of two discharges as described in Sec. 112.1(b) within twelve months, from any oil-filled operational equipment in the three years prior to the SPCC Plan certification date, or since becoming subject to 40 CFR part 112 if the facility has been in operation for less than three years.

      As proposed, the final rule provides an alternative means of SPCC compliance for this equipment; therefore, an owner or operator could choose to comply with the existing SPCC requirements to provide general secondary containment for each piece of qualified oil-filled operational equipment in accordance with Sec. 112.7(c), if desired. For example, oil-filled operational equipment at electrical substations is often surrounded by a gravel bed, which serves as a passive fire quench system and support for the facility grounding network that can restrict the movement of oil in the event of a release. Gravel beds, if designed to prevent a discharge as described in Sec. 112.1(b) (i.e., drainage systems that do not serve as a conduit to surface waters) may meet the general secondary containment requirements of Sec. 112.7(c). EPA further notes that oil-filled operational equipment located within buildings with limited drainage and which prevent a discharge as described in Sec. 112.1(b), may already meet the requirements for general secondary containment of Sec. 112.7(c).

      In some situations, permanent containment structures, such as dikes, may not be feasible (i.e., for certain electrical equipment). Section 112.7(c) allows for the use of certain types of active containment measures (countermeasures or spill response capability), which prevent a discharge to navigable waters or adjoining shorelines. Active containment measures are those that require deployment or other specific action by the owner or operator. These measures may be deployed either before an activity involving the handling of oil starts, or in reaction to a discharge so long as the active measure is designed to prevent an oil spill from reaching navigable waters or adjoining shorelines. Thus, a method of detecting a discharge is of great importance to effectively implement the use of active containment measures. If an owner or operator provides secondary containment for oil-filled operational equipment by the use of active measures, a contingency plan for this equipment is not necessary. Ultimately, the decision whether to use the optional approach to secondary containment for qualified oil-filled equipment must be made by the owner or operator. 1. Oil-Filled Operational Equipment Definition

      EPA proposed to define ``oil-filled operational equipment'' as ``equipment which includes an oil storage container (or multiple containers) in which the oil is present solely to support the function of the apparatus or the device. Oil-Filled operational equipment is not considered a bulk storage container, and does not include oil-filled manufacturing equipment (flow-through process).'' Many of the commenters supported this definition and therefore, we are finalizing this definition in today's rule and including examples in the

      [[Page 77276]]

      definition to provide additional clarity. Examples of oil-filled operational equipment include, but are not limited to, hydraulic systems, lubricating systems (i.e., those for pumps, compressors and other rotating equipment, including pumpjack lubrication systems), gear boxes, machining coolant systems, heat transfer systems, transformers, circuit breakers, electrical switches, and other systems containing oil solely to enable the operation of the device. When piping is intrinsic to the oil-filled operational equipment in a closed loop system, i.e., inherent to the equipment and used solely to facilitate operation of the device, (e.g., for lubrication) then EPA will consider the piping to be a component of the oil-filled operational equipment. However, piping not intrinsic to the operational equipment (i.e., flowlines, transfer piping or piping associated with a process) will not be considered to be part of the oil-filled operational equipment.

      The Agency received comments that included alternatives to the definition proposed. Specifically, commenters suggested that the word ``storage'' be removed from the definition of ``oil-filled operational equipment.'' The Agency disagrees with the suggestion to remove the word ``storage'' from the definition because oil-filled operational equipment includes oil inherent to the device which is stored prior to and during use for the operation of the equipment and when the oil- filled operational equipment is in standby.

      Some commenters asked that EPA identify generators (``gensets'') as oil-filled operational equipment. EPA's position is that gensets are a combination of oil-filled operational equipment and a bulk oil storage container, and the oil that is consumed to generate electricity is not inherent to the device. (The bulk storage container on a genset often requires the transfer of oil.) Therefore, although gensets incorporate oil-filled operational equipment, such as the lubrication oil system, gensets, as a whole unit, do not meet the definition of oil-filled operational equipment in today's final rule. In situations where it is impracticable to provide appropriate secondary containment for gensets (for either the bulk storage containers or oil-filled operational equipment of the genset), a PE can make a determination of impracticability in accordance with Sec. 112.7(d) and develop a contingency plan following the provisions of 40 CFR part 109 and provide a written commitment of manpower, equipment and materials to expeditiously control and remove any quantity of oil discharged that may be harmful. See Chapter 4 of the SPCC Guidance for Regional Inspectors for further explanation regarding when sized secondary containment is required for mobile or portable containers that are in a stationary, unattended mode.

      Several commenters argued that by combining oil-filled electrical with other operational equipment, EPA diluted the strong case for differentiation of oil-filled operational equipment. Commenters also suggested that EPA redefine electrical equipment to include not only circuit breakers, transformers, and electrical switches, but also hydraulic systems, lubricating systems, gear boxes, machining coolant systems, heat transfer systems, etc. In July 2002, when EPA clarified that oil-filled electrical, operating, and manufacturing equipment are not bulk storage containers, the Agency agreed to continue to evaluate whether the general secondary containment requirements found in Sec. 112.7(c) should be modified for small electrical and other types of equipment which use oil for operating purposes. Today's definition of oil-filled operational equipment describes the function of both electrical equipment, as well as other types of operating equipment (hydraulic systems, lubricating systems, etc.)

      Oil-filled electrical and operating equipment share common characteristics. They both typically have minimal oil throughput because such equipment does not require frequent transfers of oil. Further, the oil contained in oil-filled operational equipment, such as cooling or lubricating oil, is intrinsic to the operation of the device and facilitates the function of the equipment. Utilities have strong economic incentives to prevent power outages, to discover and respond to an outage, and to correct the conditions that produced the outage as quickly as possible. Other industry sectors also have strong incentives to prevent discharges to avoid disruption in business and costs of a cleanup. The Agency believes it is appropriate to allow the same alternative means of compliance with the general secondary containment requirements of Sec. 112.7(c) for oil-filled operational equipment at all facilities. In addition, oil-filled operational equipment often is subject to routine maintenance and inspections to ensure proper operation. Therefore, the Agency believes it is appropriate to allow the same alternative means of compliance with general secondary containment requirements to apply to both oil-filled electrical and operational equipment. We have included both types of equipment into the definition of oil-filled operational equipment. 2. Oil-Filled Manufacturing Equipment

      The Agency is not finalizing a definition of oil-filled manufacturing equipment because we did not propose and seek comment on a definition. Additionally, the Agency does not agree with commenters that the alternative option to general secondary containment should also apply to oil-filled manufacturing equipment. Oil-filled manufacturing equipment is inherently more complicated than oil-filled operational equipment because it typically involves a flow-through process and is commonly interconnected through piping. For example, oil-filled manufacturing equipment may receive a continuous supply of oil, in contrast to the static capacity of other, non-flow-through oil- filled equipment. Examples of oil-filled manufacturing equipment include, but are not limited to, process vessels, conveyances such as piping associated with a process, and equipment used in the alteration, processing or refining of crude oil and other non-petroleum oils, including animal fats and vegetable oils.

      The final rule does not change any requirements for oil-filled manufacturing equipment. Oil-filled manufacturing equipment remains subject to the general SPCC requirements under Sec. 112.7, including a demonstration of impracticability under Sec. 112.7(d) if the SPCC Plan does not provide for general secondary containment as required by Sec. 112.7(c). The oil storage containers associated with the storage of raw products or finished oil products are bulk oil storage containers and are not considered oil-filled manufacturing equipment or oil-filled operational equipment. Oil-filled manufacturing equipment is distinct from bulk storage containers in its purpose and is described in the SPCC Guidance for Regional Inspectors. Oil-filled manufacturing equipment stores oil only as an ancillary element of performing a mechanical or chemical operation to create or modify an intermediate or finished product. Some more specific examples of oil-filled manufacturing equipment may include reaction vessels, fermentors, high pressure vessels, mixing tanks, dryers, heat exchangers and distillation columns. Under the SPCC rule, flow-through process vessels are generally considered oil-filled manufacturing equipment since they are not intended to store oil. EPA expects the owner or operator and the certifying PE to delineate bulk storage containers from the oil- filled manufacturing equipment

      [[Page 77277]]

      in the facility's SPCC Plan (i.e., on the facility's diagram and in discussion of compliance with inspection requirements of the rule). Additionally, although oil-filled manufacturing equipment is not a bulk storage container and is therefore not subject to the frequent visual inspection requirement for bulk storage containers under Sec. 112.8(c)(6), EPA believes that it is good engineering practice to have some form of visual inspection or monitoring for oil-filled manufacturing equipment in order to prevent discharges as described in Sec. 112.1(b). Furthermore, it is a challenge to comply with several of the SPCC provisions (for example, requirements for security under Sec. 112.7(g)) and to address countermeasures for discharge discovery under Sec. 112.7(a)(3)(iv)) without some form of inspection or monitoring program. 3. Eligibility Criteria a. Reportable Discharge History

      Part 110 defines a discharge of oil in such quantities that may be harmful to the public health, welfare, or the environment of the United States as a discharge of oil that violates applicable water quality standards; a discharge of oil that causes a film or sheen upon the surface of the water or on adjoining shorelines; or a discharge of oil that causes a sludge or emulsion to be deposited beneath the surface of the water or adjoining shorelines (40 CFR 110.3). The Agency refers to such discharges as reportable discharges or as ``a discharge as described in Sec. 112.1(b)'' of the rule. Any person in charge of a facility must report any such discharge of oil from the facility to the National Response Center (NRC) at 1-800-424-8802 immediately. While EPA recognizes that past release history does not necessarily translate into a predictor of future performance, the Agency believes that discharge history is a reasonable indicator of a facility owner or operator's ability to develop an SPCC Plan for the facility without the involvement of a PE.

      Under the proposal, the alternative compliance approach for general secondary containment for oil-filled operational equipment would not be allowed to be implemented at the facility unless the owner or operator had no reportable discharge from any oil-filled operational equipment in the ten years prior to the SPCC Plan certification date, or since becoming subject to 40 CFR part 112 if the facility had been in operation for less than ten years. This criterion was based on a proposal submitted by the Utility Solid Waste Activities Group (USWAG), as described in the documents supplementing the September 20, 2004 Notice of Data Availability (NODA) at 69 FR 56184.

      Many commenters agreed with the proposed eligibility requirement. However, several comments requested that the qualifier be dropped and the type of equipment be the only qualifier. These commenters argued that reportable discharge history was not a suitable criterion for a number of reasons, including: (1) It is arbitrary and capricious-- eligibility should be rationally related to equipment or equivalent facility performance; (2) it is not effective to identify bad actors who do not report discharges; (3) it is unreasonable for crude oil and natural gas production facilities, so no requirements should apply; and (4) it does not take into consideration the volume of oil or location of equipment in assessing risk. Other commenters suggested considering the criterion for submitting reports to EPA under Sec. 112.4 to be the eligibility criterion for oil-filled operational equipment. Another commenter requested EPA clarify that the discharge is from regulated equipment, i.e., equipment that is greater than 55 gallons.

      Although EPA recognizes that past discharge history does not necessarily predict future performance, the Agency believes that discharge history can be used as a surrogate measure for a facility owner or operator's ability to appropriately manage its oil. Hence, as with ``qualified facilities,'' EPA is using this discharge history criterion to identify a facility owner or operator's ability to effectively implement its SPCC Plan and prevent discharges in quantities that may be harmful. In establishing a good oil spill prevention history for its oil-filled operational equipment, a facility then qualifies for the oil spill contingency plan option in lieu of secondary containment. Because the Agency believes it is appropriate to extend this approach to all oil-filled operational equipment, regardless of the oil storage capacity of the equipment, the spill history criterion is critical to establish an appropriate balance between environmental protection and streamlined requirements by identifying those facilities whose owners or operators have demonstrated good spill prevention practices in the past.

      EPA does not agree that this is unreasonable for crude oil and natural gas production facilities because the reportable discharge criterion is applicable only to the oil-filled operational equipment at the facility and is not affected by other discharges that may have occurred from the facility from other types of oil storage containers. One commenter pointed out that discharges from compressors, pumpjacks, and similar equipment are extremely rare and unlikely to reach navigable waters and adjoining shorelines.

      Many commenters suggested an alternate reportable discharge history period of five years. One commenter suggested three years and another suggested either two or five years. A few commenters suggested the time period should be five years with a Sec. 112.4 spill notification trigger.

      In response to comments received on the proposed rule, EPA has reduced the discharge history period from ten years to three years, which is consistent with the recordkeeping requirements in Sec. 112.7(e). In addition, rather than including all discharges reportable to the National Response Center, the Agency is specifying amounts of more than 1,000 U.S. gallons in a single discharge as described in Sec. 112.1(b) or more than 42 U.S. gallons in two discharges as described in Sec. 112.1(b) within a twelve month period during the three-year timeframe, or since becoming subject to 40 CFR part 112 if the facility has been in operation for less than three years, only from oil-filled operational equipment at the facility. This criterion does not include oil discharges as described in Sec. 112.1(b) that are the result of natural disasters, acts of war, or terrorism. The approach is similar to the discharges that are reportable to the Regional Administrator under Sec. 112.4(a), with the exception that the criterion finalized today applies only to discharges from oil-filled operational equipment and not all oil containers at a facility as in the case of Sec. 112.4(a). When determining spill history, the gallon amount specified in the criterion (either 1,000 or 42) refers to the amount of oil that actually reaches waters of the United States, adjoining shorelines, the contiguous zone or in connection with specified activities in waters and not the total amount of oil spilled. For example, a facility only experiencing one discharge over the past ten years in which 1,500 gallons of oil discharged onto the ground but only 20 gallons reached waters of the United States (causing a sheen and reportable to the NRC) would meet the Reportable Discharge History criterion. However, a facility having 1,500-gallon discharge to waters of the United States would not meet the Reportable Discharge History criterion.

      The determination of eligibility based on reportable discharge history is made at the time the SPCC Plan is certified.

      [[Page 77278]]

      That is, when the SPCC Plan is amended to comply with the SPCC rule revisions in today's final rule and those promulgated in July 2002. Once the current compliance date extension ends, Plans must be amended, certified and implemented. Any discharges to navigable waters and adjoining shorelines that occur from oil-filled operational equipment at the facility after the SPCC Plan has been certified do not impact the eligibility of qualified oil-filled operational equipment at the facility. The facility does not lose eligibility status as a result of a discharge as described in Sec. 112.1(b), unless the RA requires an amendment to the SPCC Plan in accordance with Sec. 112.4(d) and specifically requires secondary containment for oil-filled operational equipment. If an owner or operator cannot certify that the oil-filled operational equipment meets the eligibility criterion at the initial date of Plan certification, but can later demonstrate a clean spill history of three years, then a technical amendment to the Plan can be certified and the Plan can be revised to allow for qualified status for oil-filled operational equipment.

      In the preamble to the proposed rule, EPA requested comment on how extreme events such as natural disasters and acts of war, terrorism , sabotage, or other calamities might potentially affect the discharge history criterion for qualified facilities. Many commenters agreed (and no commenters disagreed) that EPA should account for extreme events such as natural disasters, acts of war or terrorism, etc. in granting eligibility status. The Agency agrees that reportable discharges caused by external factors beyond the control of the facility owner or operator such as natural disasters, acts of war, or terrorism should not disqualify a facility from eligibility for the qualified oil-filled equipment provision. Therefore we have excluded those events from consideration in the reportable discharge eligibility criterion in today's final rule. The Agency has excluded sabotage/vandalism from the final list of extreme events not to be considered in the reportable discharge history because these are not necessarily beyond the control or planning ability of the facility owner or operator. b. Consideration of Alternative Qualification Criteria

      One commenter suggested that the inspection and monitoring program be the only qualifier for a facility owner or operator to take advantage of this option. Other suggestions would allow eligibility to be based on the type of equipment and a commitment or duty to properly maintain that equipment such as the duty in 40 CFR 122.41(e) to maintain wastewater treatment equipment. In this case, facility owners or operators would lose eligibility based on their performance or SPCC inspection results (i.e. failure to maintain oil-filled electrical equipment). The Agency is not finalizing these alternatives as part of the eligibility criteria because we believe it is in the owner or operator's best interest to properly maintain equipment at the facility and a commitment to the Agency to maintain equipment is not necessary.

      The Agency believes that inspections and monitoring are part of an effective spill prevention program and it is more appropriate to include these prevention practices as a component of the alternative option for compliance with general secondary containment requirements for oil-filled operational equipment. To include these spill prevention practices as a basis for qualification raises questions on the length of time and scope of the inspection and monitoring program necessary to be in place at the facility in order to demonstrate qualification.

      Additionally, the SPCC regulations already provide EPA the authority to require SPCC Plan amendments under Sec. 112.4 so it is not necessary to include an automatic loss of eligibility based on facility performance or SPCC inspection results. Section 112.4(a) requires an owner or operator of a facility that has discharged more than 1,000 U.S. gallons of oil in a single discharge as described in Sec. 112.1(b) or that has discharged more than 42 U.S. gallons of oil in each of two discharges as described in Sec. 112.1(b) within any twelve month period, to submit information to the EPA RA within 60 days of the date of the discharge. As per Sec. 112.4(d), the RA may require the facility owner or operator to amend the SPCC Plan in order to prevent and contain discharges, including a requirement that a facility owner or operator provide secondary containment for qualified oil- filled operational equipment. The time frame for this review and amendment process is described in Sec. 112.4. The facility owner or operator may choose to appeal the RA's decision to require a Plan amendment under Sec. 112.4. In addition, a discharge of oil ``in such quantities as may be harmful'' as defined in 40 CFR 110.3 that does not trigger the reporting requirements of Sec. 112.4(a) must still be reported to the National Response Center. Criminal action can be taken against an owner or operator of a facility if discharges are willfully not reported. EPA also receives copies of the NRC reports and has the authority under Sec. 112.1(f) to require a facility owner or operator to prepare and implement an SPCC Plan or any applicable part of a Plan.

      Owners and operators of facilities with qualified oil-filled operational equipment that choose the alternative to secondary containment and that subsequently have a discharge would not automatically lose eligibility for today's optional approach. Owners or operators of facilities that discharge oil in quantities that may be harmful from oil-filled operational equipment should re-evaluate the effectiveness of the SPCC Plan (specifically the contingency plan, written commitment of resources, and inspections/monitoring alternative discussed in today's final rule) and determine the need for secondary containment measures in lieu of contingency planning. Additionally, the Regional Administrator may determine that a facility owner or operator is no longer eligible to have a contingency plan in lieu of secondary containment without making an impracticability determination, and such owners or operators may be required to amend their Plans to provide secondary containment for their oil-filled operational equipment. 4. Requirements for Qualified Oil-Filled Operational Equipment In Lieu of Secondary Containment a. Contingency Plans and a Written Commitment of Manpower, Equipment, and Materials

      As described in the preamble to the proposed rule, EPA believes that secondary containment often may be impracticable for oil-filled operational equipment because of inherent design and safety considerations, as well as site configuration. The oil associated with oil-filled operational equipment remains inside the equipment and transfers do not occur regularly; for oil-filled electrical equipment (i.e., transformers) transfers typically occur infrequently, if at all. The complexity of the equipment and the nature of the use of this equipment does not lend itself to traditional bulk storage containment methods and thus flexibility is appropriate in this area and may improve compliance with oil pollution prevention measures. EPA proposed amendments to Sec. 112.7 to give owners and operators of facilities with qualified oil-filled operational equipment the option of implementing an inspection and monitoring program, developing an oil spill contingency plan and providing a written commitment of resources

      [[Page 77279]]

      required to expeditiously control and remove any quantity of oil discharged that may be harmful, in lieu of secondary containment for this equipment, without having to make an impracticability determination for each piece of oil-filled operational equipment. The inspection and/or monitoring program, contingency plan and written commitment of resources would be included in the facility SPCC Plan. Commenters generally supported this proposal and the provision is being finalized in Sec. 112.7(k) as proposed.

      A number of commenters were unclear regarding the intent of an oil spill contingency plan. For example, a common industry interpretation of an ``oil spill contingency plan'' covers anticipated responses to oil spills both on land, as well as spills that reach navigable waters. Some commenters suggested that the contingency plan be in lieu of an SPCC Plan entirely. Others suggested that it is an administrative burden to identify downstream water users and the majority of commenters suggested that it is inappropriate to consider large discharges to water since the goal should be to prevent oil from getting to navigable waters in the first place. Several commenters suggested that implementation of a contingency plan in accordance with the requirements of 40 CFR part 109 was inappropriate because the purpose of the contingency plan should be to prevent a discharge to navigable waters and adjoining shorelines.

      Commenters suggested that the oil spill contingency plan should instead contain four major elements: hazard identification, vulnerability analysis, risk assessment and response actions. Many of the commenters that suggested simplifying the contingency planning option to allow for hazard identification, vulnerability analysis, risk assessment, and response actions may already be in compliance with the general secondary containment requirements of the SPCC rule by utilizing active secondary containment measures.

      We do not believe that a contingency plan, by itself, is sufficient to substitute for an SPCC Plan. The purpose of the SPCC Plan is to prevent discharges of oil from reaching navigable waters and adjoining shorelines and includes a combination of procedures, measures and equipment to achieve that goal, e.g., procedures for inspections and personnel training, equipment to prevent and control discharges of oil and security measures. Conversely, a contingency plan is a detailed oil spill response and removal plan that addresses controlling, containing, and recovering an oil discharge in quantities that may be harmful to navigable waters or adjoining shorelines. Contingency plans have a dual purpose. The first purpose is to outline the response capability or countermeasures to limit the quantity of a discharge from reaching navigable waters or adjoining shorelines (if possible). The second is to address the facility owner or operator's effective preparation for a response to a discharge of oil that has already reached navigable waters or adjoining shorelines. A contingency plan should include the ability to expeditiously control and remove any quantity of oil discharged that may be harmful.

      The elements of the contingency plan are outlined in Sec. 109.5, and include: definition of the authorities, responsibilities, and duties of all persons, organizations, or agencies that are to be involved or could be involved in planning or directing oil removal operations; establishment of notification procedures for the purpose of early detection and timely notification of an oil discharge; provisions to ensure that full resource capability is known and can be committed during an oil discharge situation; provisions for well-defined and specific actions to be taken after discovery and notification of an oil discharge; and specific and well-defined procedures to facilitate recovery of damages and enforcement measures as provided for by state and local statutes and ordinances.

      An owner or operator of a facility with oil-filled operational equipment that has submitted a Facility Response Plan (FRP) to EPA in accordance with Sec. 112.20 would not need to also develop a contingency plan in accordance with 40 CFR part 109 for the oil-filled operational equipment because an FRP is more comprehensive than a contingency plan. Additionally, the contingency planning requirement can be met either by a whole new plan or by ensuring that the elements called for in 40 CFR part 109 and the accompanying written commitment of manpower, equipment and materials are integrated into the SPCC Plan or another plan already in place at the facility (provided that a section cross-referencing the location of requirements listed in 40 CFR part 109 and the equivalent requirements in the other response plan is included).

      For a contingency plan to satisfy the requirements listed in Sec. 112.7(k) of today's final rule, a facility owner or operator must be able to implement the contingency plan. Activation of the contingency plan depends on the capability of the owner or operator of the facility to quickly detect a discharge. Therefore, as part of an evaluation of the adequacy of a contingency plan to satisfy the requirements of Sec. 112.7(k), EPA will consider the time it takes facility personnel to detect and mitigate a discharge as described in Sec. 112.1(b).

      Inspections or monitoring are particularly important to detect an oil discharge when there is no secondary containment in place. Therefore, EPA proposed and is finalizing the provision to require owners and operators of facilities with qualified oil-filled operational equipment that choose to develop and implement contingency plans to also develop and implement an inspection or monitoring program, as further discussed in this section of the preamble. Because the qualified oil-filled operational equipment approach is optional, an owner or operator of a facility with such equipment may choose to provide general secondary containment in accordance with Sec. 112.7(c) for this oil-filled operational equipment, if desired. Ultimately, this is the decision of the owner or operator of the facility.

      The comments received suggest there is a misunderstanding concerning the general secondary containment requirements of Sec. 112.7(c). General secondary containment under Sec. 112.7(c) should be designed to address the most likely discharge from the primary containment system, i.e., appropriate containment and/or diversionary structures or equipment must be designed to prevent a discharge as described in Sec. 112.1(b). Secondary containment may be either passive measures or active measures (countermeasures or land-based spill response capability) since both are designed to prevent a discharge from reaching navigable waters or adjoining shorelines.

      Passive measures are permanent installations (such as dikes or berms) and do not require deployment or action by the owner or operator. However, permanent (passive) containment structures, such as dikes, may not always be feasible for certain oil-filled operational equipment (i.e., electrical transformers, capacitors, switches). The owner or operator of an SPCC-regulated facility may instead use the flexibility of active containment measures to comply with the general secondary containment requirements for oil-filled operational equipment.

      Active containment measures are those that require deployment or other specific action by the owner or operator of a facility. These active measures may be deployed either before an activity involving the handling of oil starts, or in reaction to a discharge, so long as the

      [[Page 77280]]

      active measure is designed and can reasonably be implemented to prevent an oil spill from reaching navigable waters or adjoining shorelines. The efficacy of active secondary containment measures to prevent discharges depends on their technical effectiveness (i.e., mode of operation, absorption rate), placement and quantity, and timely deployment prior to, or following a discharge. A method of detecting a discharge is therefore of great importance to effectively implement the use of active containment measures. These active measures must be implemented effectively and in a timely manner to prevent oil from reaching navigable waters and adjoining shorelines, as required by Sec. 112.7(a)(3)(iii) and (c).

      Many commenters indicated that the 40 CFR part 109 plan is designed for local governments and therefore inappropriate for facilities. Some commenters suggested using environmental equivalence to tailor a 40 CFR part 109 plan or allow flexibility for facility owners and operators to comply only with applicable requirements. Other commenters suggested the use of generic and multi-facility plans. Some commenters suggested expanding the training requirements to apply to more than just the oil- handling personnel at the facility. Commenters also indicated that it is onerous to list each piece of equipment in a Plan, and that it is burdensome to keep the Plan up-to-date to account for mobile equipment.

      Environmental equivalence is available to allow for alternative means of fulfilling the same function as the specific provision listed in Sec. 112.7(a)(2). Because the contingency plan elements in part 109 do not contain specific requirements as to how those elements are fulfilled, there is no need to provide for environmentally equivalent means of fulfilling those requirements, Thus, the Agency believes that there is already sufficient flexibility in the criteria for an oil spill contingency plan in 40 CFR part 109. Moreover, since the purpose of the plan is to prepare for response to a discharge of oil that has reached navigable waters or adjoining shorelines, each of the elements of a contingency plan listed in 40 CFR part 109 are appropriate. Although the elements of a contingency plan listed in 40 CFR part 109 were originally developed to outline procedures for local and regional oil removal contingency plans, these elements can be adapted for SPCC regulated facilities. A sample contingency plan adapted to the needs of an SPCC-regulated facility following the provisions of 40 CFR part 109 is included in Appendix F of the SPCC Guidance for Regional Inspectors which is available on the EPA Web site at http://www.epa.gov/oilspill.

      The guidance document also provides more information on active and passive secondary containment measures.

      Other commenters suggested the use of generic and multi-facility SPCC Plans. In July 2002, the Agency stated that a multi-facility SPCC Plan may be appropriate for operating equipment (oil-filled operational equipment) (see 67 FR 47042, 47080.) This type of SPCC Plan is intended for electrical utility transmission systems, electrical cable systems, and similar facilities whose owners and operators might aggregate equipment located in diverse areas into one Plan. Multi-facility Plans would include all elements required for individual SPCC Plans. Site- specific information would be required for all equipment included in each Plan. However, the site-specific information might be maintained in a separate location, such as a central office, or an electronic database, as long as such information was immediately accessible to responders and inspectors. If you keep the information in an electronic database, you must also keep a paper or other backup that is immediately accessible for emergency response purposes, or for EPA inspectors, in case the computer is not functioning. It is not clear what the commenters meant by a generic Plan, however, the Agency believes that any Plan developed must be in accordance with the requirements of 40 CFR part 112.

      Commenters recommended that training at a facility be expanded beyond the personnel involved in oil handling, with one commenter suggesting that training include any individuals who could reasonably be expected to implement any component of the contingency plan; they also suggested rule language for such an approach. The Agency agrees that any employee who is required to implement any component of an oil spill contingency plan may be considered ``oil-handling personnel'' and require training in accordance with Sec. 112.7(f). This would consist of training in the operation and maintenance of equipment to prevent discharges; discharge procedure protocols; applicable pollution control laws, rules and regulations; general facility operations; and the contents of the facility SPCC Plan (including the contingency plan). Contractors involved in oil handling activities at the facility should also have appropriate oil spill response training.

      Additionally, commenters indicated that it is onerous to list each piece of equipment in an SPCC Plan, and that it is burdensome to keep the Plan up-to-date to account for mobile equipment. The Agency agrees that it may be burdensome to frequently update an SPCC Plan for mobile equipment. However, we believe there is sufficient flexibility in the SPCC rule to address this concern. For example, EPA has stated that if you store mobile containers in a certain area, you must mark that area on the diagram. You may mark the contents of each container either on the diagram of the facility, or on a separate sheet or log if those contents change on a frequent basis. More information on the flexibility of the SPCC rule for mobile/portable containers is available in the SPCC Guidance for Regional Inspectors available on the EPA Web site at http://www.epa.gov/oilspill.

      1. Inspections or Monitoring Program

      The majority of commenters supported the proposal to include an inspection and monitoring program. A facility owner or operator must be able to quickly detect a discharge from oil-filled operational equipment in order for a contingency plan to be effective. Therefore, the Agency is including a requirement for an inspection and monitoring program in today's rule. Facility owners or operators who wish to take advantage of this alternative are required to develop an appropriate set of procedures for inspections or a monitoring program for qualified oil-filled operational equipment. For facility owners and operators that rely on contingency planning in lieu of secondary containment for qualified oil-filled operational equipment, the discovery of a discharge by inspection or monitoring is of paramount importance for effective and timely implementation of the contingency plan. An inspection or a monitoring program ensures that facility personnel are alerted quickly of equipment failures and/or discharges. A written description of the inspection or monitoring program is required to be included in the SPCC Plan. Under the requirement in Sec. 112.7(e), the owner or operator is required to keep a record of inspections and tests, signed by the appropriate supervisor or inspector, for a period of three years.

      Although oil-filled operational equipment is not a bulk storage container and is therefore not subject to the frequent visual inspection requirement for bulk storage containers under Sec. 112.8(c)(6), EPA believes that it is good engineering practice to have

      [[Page 77281]]

      some form of visual inspection or monitoring for oil-filled operational equipment in order to prevent discharges as described in Sec. 112.1(b). Therefore, in lieu of secondary containment, the proposal included the requirement for a facility owner or operator to establish and document an inspection or monitoring program, in addition to the preparation of a contingency plan and a written commitment of manpower, equipment, and materials to expeditiously control and remove discharged oil. One commenter suggested requiring only inspection and monitoring for oil-filled operational equipment up to 5,000-gallon capacity and no other written Plan. The Agency continues to believe that a written SPCC Plan is essential to document the prevention procedures and countermeasures employed at the facility and is necessary for effective implementation of an SPCC program, or any other program (business or otherwise). As a matter of practice, it would be extremely difficult for a facility owner or operator to be able to follow the regulatory requirements and to comply with all the recordkeeping components without the documentation that is the Plan itself. The Plan also serves as an important communication tool for both management and operators at the facility. The sole action of having to document all of the requirements can assist in uncovering flaws in the program implementation, and may serve as a tool to correct them. The Plan is also used to communicate these procedures and measures to employees. Additionally, the documentation of compliance with the rule's requirements in a written Plan serves as a facility specific oil spill response and prevention planning exercise which is designed to improve oil spill prevention. c. Alternative Options Considered

      Many commenters believed, and supported the Agency's proposal to not include, a capacity threshold qualifier. There was also significant support for the USWAG multi-tiered option for electrical equipment, with some commenters suggesting that the Agency differentiate between electrical and other oil-filled operational equipment and then adopt the USWAG proposal providing an exemption for most small equipment. Other commenters specifically commended EPA for not including a volume threshold for applicability of relief based on lack of data to suggest that large oil-filled equipment have greater potential for discharge over small oil-filled equipment. However, these commenters indicated that small equipment should be exempt because of lack of spill data. Multiple commenters requested exemption or deferral requirements in the same manner as proposed for farms. Others requested suspension of the requirements.

      The Agency agrees with commenters that no threshold qualifier is necessary to allow for an alternative means of compliance with secondary containment requirements for oil-filled operational equipment. The alternative measure is appropriate based on the type of equipment, i.e., the oil is intrinsic to the operational equipment and present solely to support the apparatus and there is minimal oil throughput because such equipment does not require frequent transfers of oil. The Agency did not finalize the multi-tiered approach for electrical equipment to allow for an exemption for smaller pieces of oil-filled operational equipment because we believe there is still a reasonable potential for discharges from oil-filled operational equipment with an oil storage capacity of 1,320 gallons or less, thus coverage by some type of SPCC Plan is warranted. An exemption of these smaller pieces of oil-filled operational equipment could in some cases allow for large amounts of aggregate capacity that would not be counted for SPCC or FRP purposes, and would therefore be unregulated, posing a threat to the environment. However, in the July 17, 2002 Federal Register notice, EPA stated ``We believe that it is not necessary to apply SPCC or FRP rules requiring measures like secondary containment, inspections, or integrity testing, to containers smaller than 55 gallons storing oil because a discharge from these containers generally poses a smaller risk to the environment.'' (67 FR 47066). Oil-filled operational equipment with a capacity of less than 55 gallons is not subject to the rule.

      Oil-filled electrical and operating equipment share common characteristics. They both typically have minimal oil throughput because such equipment does not require frequent transfers of oil. Further, the oil contained in oil-filled operational equipment, such as cooling or lubricating oil, is intrinsic to the operation of the device and facilitates the function of the equipment. Should oil-filled electrical equipment fail, utilities responsible for such equipment have strong economic incentives to prevent power outages, to discover and respond to an outage, and to correct the conditions that produced the outage as quickly as possible to prevent an oil discharge. Similarly, when other critical oil-filled operating equipment fails, the industry sectors responsible for such equipment also have strong incentives to respond and address failures to avoid disruption in business and costs of a cleanup. In addition, oil-filled operational equipment often is subject to routine maintenance and inspections to ensure proper operation. Therefore, the Agency is not promulgating different requirements, but believes it is appropriate to offer the same alternative means of compliance with the general secondary containment requirements of Sec. 112.7(c) to both oil-filled electrical and operational equipment. Both types of equipment are addressed in the definition of oil-filled operational equipment.

      The Agency has decided not to provide an indefinite extension or suspension for owners and operators of facilities with oil-filled operational equipment. The regulated community, particularly owners and operators of electrical facilities, identified secondary containment for oil-filled operational equipment as one of its major cost concerns. Today's rule addresses that concern and offers an alternative means of compliance for oil-filled operational equipment, while maintaining protection of human health and the environment. 5. Qualified Oil-Filled Operational Equipment and Qualified Facilities Overlap

      Some facilities will meet the criteria for qualified facilities and have qualified oil-filled operational equipment on-site. Owners and operators of such facilities are able to benefit from both of the alternative compliance approaches finalized in today's rule. The owner or operator can choose to develop an oil spill contingency plan, a written commitment of manpower, equipment and materials and an inspection or monitoring program as an alternative to secondary containment for qualified oil-filled operational equipment. Since no impracticability determination is necessary for qualified oil-filled operational equipment, the owner or operator can self-certify his/her SPCC Plan and is not required to have a PE develop and certify the contingency plan for the qualified oil-filled operational equipment. The responsibility of preparing a contingency plan and identifying the necessary equipment, materials and manpower to implement the contingency plan would fall on the owner or operator of the qualified facility.

    4. Motive Power

      In the proposed rule, EPA addressed specific types of motor vehicles (including aircraft, buses, sport utility vehicles, small construction vehicles, cherry pickers, self-propelled cranes, self- propelled aviation ground service equipment vehicles, self-propelled forestry, agricultural, construction, and excavation vehicles and locomotives) that contain oil in capacities greater than or equal to 55 gallons solely for the purpose of providing fuel for propulsion, or solely to facilitate the operation of the vehicle, such as lubrication of moving parts or operation of onboard hydraulic equipment. Such oil storage containers are technically subject to the SPCC rule, including the requirement for secondary containment and other SPCC requirements. This means that heavy equipment dealers, commercial truck dealers, or certain parking lots may be subject to the SPCC requirements (including bulk storage secondary containment, inspection, and overfill protection) solely because of the presence of motive power containers. EPA never intended to regulate these motive power containers or facilities where these vehicles might be located and who are not otherwise subject to the SPCC requirements because of the impracticability of application of the SPCC requirements to such vehicles. These individually provide their own means of propulsion from location to location within or between facilities. The management, record keeping, and compliance with the spill prevention requirements associated with motive power containers would be difficult due to their movement throughout and between facilities. For example, a truck with a large fuel tank and associated large capacity hydraulic units that moves throughout a facility and between facilities would require tracking and containment under the SPCC requirements. This is impracticable because such vehicles are not stationary or located in a specific operational area, as is the case with mobile non-vehicular mobile/portable containers that are placed in specific oil handling or operational areas. Motor vehicles with a storage tank capacity of 55 gallons or greater, such as a number of semi-rigs delivering materials to an otherwise regulated SPCC facility that enter and leave a facility on a routine basis would provide a significant challenge for compliance with the SPCC requirements. Finally, these containers are either ``end use'' fuel tanks or oil-filled operational equipment in which transfers from the container are rare unlike other mobile portable containers. To correct this unintended application of the SPCC rule, EPA proposed to exempt motive power containers from the SPCC requirements. Commenters generally favored this proposal and agreed that subjecting motive power containers to SPCC requirements would be impracticable. In today's action, EPA is clarifying its position on motive power containers associated with self-propelled motor vehicles by finalizing the proposed definition and exemption.

      The Agency believes that the general protection and the spill response and planning activities in place at an otherwise regulated SPCC facility will address any discharges associated with these motive power containers.

      For those facilities whose capacity is comprised solely of motive power containers, today's action may result in the facility no longer being subject to the SPCC requirements. However, for owners and operators of these facilities, EPA maintains the authority, under 311(j)(1)(C) of the CWA, to impose requirements to prevent oil discharges from motive power containers. EPA believes that owners and operators of these facilities will continue to act prudently to prevent discharges from motive power containers from reaching navigable waters and owners and operators of non-transportation-related facilities that fail to do so can be required by the EPA Regional Administrator (RA) to develop an SPCC Plan. The RA has the option under Sec. 112.1(f) to require owners and operators of facilities, including those with motive power containers, to prepare and implement an SPCC Plan or any applicable part, if a determination is made that it is necessary to prevent a discharge of oil into waters of the United States. EPA will continue to encourage owners and operators of facilities that are no longer regulated under the SPCC rule, as a result of today's action, to provide prevention, planning and response measures to prevent oil discharges from motive power containers. 1. Definition of Motive Power

      One commenter generally supported the definition as proposed. Several other commenters opposed the proposed definition and additional comments were submitted with alternate definitions of motive power containers. Those who opposed the definition indicated that it will not effectuate its purpose, simply because the gas tank, for example, is not used solely to power the movement of a motor vehicle. Other reasons for opposition note that the definition may not be broad enough, and it should be modified to clarify the scope of ``motor vehicle.'' The definition may not cover all motive power configurations, and it may not cover ground service equipment, including ground service equipment in the airport industry sector.

      Recommendations included expanding the definition to include other mobile equipment like forestry and mining equipment. Other commenters indicated that the scope of the definition should be modified to clarify that a motor vehicle includes not just automobiles and trucks, but all types of motor vehicles including cranes, cherry pickers, or production drill rigs at mining sites and equipment that may be stationary for a temporary duration. Commenters also suggested that the definition be revised to cover various motive power configurations.

      EPA agrees with the commenters that the scope of the definition should be clarified to include motor vehicle bulk storage containers that serve a non-operational purpose in addition to the propulsion of the motor vehicle (for example, a bulk storage container that supplies fuel to an engine which provides the propulsion for that motor vehicle, as well as its auxiliary units and functions (i.e., heaters, air conditioning units, and electrical power generation, etc.). As noted by commenters, the term ``solely'' in the definition of motive power containers limits the inclusion of motor power fuel tanks that serve one of the non-operational functions listed above in addition to providing fuel for propulsion of the motor vehicle. In response to this comment, EPA has removed the word ``solely'' and replaced it with the word ``primarily.'' The definition of motive power containers only applies to motor vehicles where the primary purpose of the bulk storage container is to supply fuel to power the movement of the vehicle and, secondly, power other equipment on board the vehicle, so long as no further distribution (transfers) of oil occurs from the container as in the case with some mobile refuelers.

      EPA agrees with the commenters that additional clarification is needed to describe the type of motor vehicles covered under the definition of motive power containers. Only motor vehicles which provide their own means of propulsion fall within the scope of this definition for the purposes of 40 CFR part 112. For example, aircraft, cherry pickers, self-propelled cranes, self-propelled aviation ground service equipment vehicles, self-propelled heavy (forestry, agricultural, mining, excavation and construction) vehicles and locomotives, all of which

      [[Page 77283]]

      individually provide their own means of propulsion from location to location within a facility or between facilities, are considered motor vehicles for the purposes of this definition and 40 CFR part 112. However, towed aviation ground service equipment, non-self-propelled construction/cargo cranes, non-self-propelled (forestry, agricultural, mining, excavation or construction) equipment, diesel powered generators, fire pumps, and compressors are examples of oil-filled equipment and bulk storage containers not considered motor vehicles for the purposes of this definition because they do not provide their own means of propulsion. The exemption was based on the impracticability of application of SPCC requirements to motor vehicles and their unique self-propelled capability of movement within and between facilities, typically without restriction. 2. Exemption

      This final rule amendment exempts motive power containers, as defined above, from SPCC rule applicability by adding a new paragraph (7) under the general applicability section, Sec. 112.1(d). Furthermore, the capacity of these storage containers are not counted toward facility oil storage capacity under Sec. 112.1(d)(2). The RA has the option under Sec. 112.1(f), however, to require owners and operators of facilities, including those with motive power containers, to prepare and implement an SPCC Plan or any applicable part, if a determination is made that it is necessary in order to prevent a discharge of oil into waters of the United States, or adjoining shorelines.

      EPA notes that although this amendment provides an exemption from the SPCC requirements for the fuel tanks and ancillary onboard oil- filled operational equipment of motor vehicles, the oil transfer activities occurring within an SPCC-covered facility continue to be regulated. An example of such an activity would be the transfer of oil from an on-site tank via a dispenser to a motive power container. This transfer activity is subject to the general secondary containment requirements of Sec. 112.7(c).

      An onboard bulk storage container that supplies oil for the movement of a vehicle or operation of onboard equipment, and at the same time, is used for the distribution or storage of this oil, is not eligible for this exemption. For example, a mobile refueler that has an onboard bulk storage container used to distribute fuel to other vehicles on a site may also draw its engine fuel (for propulsion) from that bulk container. However, such bulk storage containers (on a mobile refueler, as defined in today's rule under 112.2) are exempt from the sized secondary containment requirements in Sec. Sec. 112.8(c)(2) and (11) and 112.12(c)(2) and (11), as applicable (see Section D below).

      EPA is also not extending the exemption for motive power containers to oil drilling and workover equipment, including rigs. The Agency believes that because of the unique nature of oil drilling and workover rig operations and the large amounts and high flow rates of oil associated with these activities, it would not be appropriate or environmentally sound to exempt them from the SPCC requirements, and thus they remain subject to 40 CFR part 112. Although drilling and workover rigs are not exempt, other types of motive power containers located at drilling or workover facilities (i.e., trucks, automobiles, bulldozers, seismic exploration vehicles, or other earth-moving equipment) are exempted. The Agency believes that the general protection and the spill response and planning activities provided at an otherwise regulated SPCC facility will help the facility owner or operator to address any spills associated with these motive power containers. However, the specific provisions (such as blowout prevention), which are present in the rule for drilling or workover rigs, need to be preserved to maintain an adequate level of environmental protection for these unique activities. Therefore, an exemption for drilling and workover equipment, including rigs, is inappropriate.

      Some commenters, representing the aviation, forestry, mining, recycling, and construction industries, requested that stationary cranes, gensets, and other non-self-propelled operational and towed ground service equipment be included in the exemption. The Agency believes that where these kinds of non-self-propelled, stationary or towed equipment operate in pre-determined oil handling areas, an SPCC Plan can reasonably address oil spill prevention measures under Sec. 112.8(c)(2) and (11). For example, the Agency understands that towed ground service equipment at an airport is typically located at terminal gates for use when aircraft are parked at the gates. This equipment typically is staged and operated in an area that includes other oil storage containers such as airport mobile refuelers (see Section D below). As such, the identified oil spill prevention approach that addresses potential spills from an airport mobile refueler at the gate should also address potential spills from nearby ground service equipment used by airline personnel at the same gate. Thus, the exemption does not include non-self-propelled stationary or towed equipment, such as towed ground service equipment or any type of gensets, but only motor vehicles that can provide propulsion to another location. See Chapter 4 of the SPCC Guidance for Regional Inspectors for further explanation regarding when sized secondary containment is required for mobile or portable containers that are in a stationary, unattended mode.

    5. Mobile Refuelers

      EPA proposed to amend the SPCC rule to define an airport mobile refueler as a vehicle with an onboard bulk storage container designed or used solely to store and transport fuel for transfer into or from aircraft and ground service equipment (such as belt loaders, tractors, luggage transport vehicles, deicing equipment, and lifts) at airports. Airport mobile refuelers have onboard bulk storage containers that are used solely to transport and transfer fuel and are subject to the SPCC rule because they are containers used to store oil prior to further distribution and use. As such, they are subject to all applicable SPCC rule provisions, including the sized secondary containment provisions of Sec. Sec. 112.8(c)(2) (applicable to all bulk storage containers) and 112.8(c)(11) (applicable more specifically to mobile/portable bulk storage containers). These provisions require a secondary means of containment, such as a dike or catchment basin, sufficient to contain the capacity of the largest single compartment or container with sufficient freeboard to contain precipitation.

      As described in the preamble to EPA's proposed rule, members of the aviation sector have expressed concern that requiring sized secondary containment for airport mobile refuelers is not practicable for safety and security reasons. They argued that requiring refuelers to park in specifically sized secondary containment areas located within an Airport Operations Area (AOA) could create a safety and security hazard because it entails grouping the vehicles or placing impediments in the AOA. In response to these concerns, EPA proposed to exempt airport mobile refuelers from the specifically sized secondary containment requirements for bulk storage containers in Sec. 112.8(c)(2) and (11), while preserving environmental protection (especially for fuel transfers associated with airport mobile refuelers), afforded by the spill

      [[Page 77284]]

      prevention provisions outlined in Sec. 112.7(c).

      Members of the aviation sector were generally supportive of the proposal. Commenters generally supported the proposed exemption of airport mobile refuelers from certain provisions of the SPCC regulations and noted that general secondary containment is already practiced at airports. Commenters stated that requiring secondary containment around airport mobile refuelers, while they are stationary or idle creates serious safety and security risks. One commenter did have reservations about certain provisions of the rule still governing airport mobile refuelers, specifically the provisions of Sec. 112.8(c) and the general secondary containment requirements of Sec. 112.7(c). A Professional Engineering firm opposed the exemption of airport mobile refuelers from certain provisions of the SPCC regulation. The commenter asserted that the argument regarding the accident potential for not excluding airport fuel transporters is highly questionable, since airport fuel spills are well documented.

      The Agency agrees with the commenter that fuel spills at airports are well documented, and that potential spills from airport mobile refuelers need to be addressed in the facility's SPCC Plan. Nevertheless, the Agency agrees with those commenters that argued that the sized secondary containment requirement did present safety and security concerns and therefore, we are finalizing the proposal to exclude mobile refuelers as defined in today's rule in Sec. 112.2 from the specifically sized secondary containment requirements for bulk storage containers in Sec. Sec. 112.8(c)(2) and (11) and 112.12(c)(2) and (11). General secondary containment still applies for mobile refuelers at non-transportation-related facilities, unless permanently closed as defined in Sec. 112.2.

      Although the Agency did not propose to extend this exclusion to other mobile refuelers that may operate within the confines of a non- transportation facility, we requested comment as to whether the proposed exclusion should be more broadly applied to other types of mobile refuelers. Commenters responded that the proposed exclusion for airport mobile refuelers from the sized secondary containment requirements should be extended to mobile refuelers at industrial sites, construction sites, chemical complexes (i.e., refineries), mining sites, seaport terminals, and tank truck home bases. Several commenters indicated that the same rationale discussed in the proposed rule preamble supporting this exclusion applies to owners and operators of industrial facilities as well. Specifically, one commenter stated that: (1) Requiring sized secondary containment for industrial mobile refuelers is not practicable and distracts from safety and security monitoring by providing a blind spot and hiding location behind the containment unit; (2) requiring refuelers to park in specially designated secondary containment areas located within an industrial or chemical facility operating area will create safety and security hazards by grouping the vehicles or placing impediments in the operations area; and (3) requiring mobile refuelers to return to containment areas located within the industrial facilities tank farm between refueling operations will increase the risk of accidents (and therefore accidental oil discharge), as the vehicles would travel with increased frequency through the busy industrial operating areas. Another commenter also indicated that the clarification should extend to rail cars, since rail cars are less mobile then airport mobile refuelers and additional rail car movements in congested rail yards exposes these vehicles to many of the hazards identified for airport mobile refuelers.

      The Agency agrees with commenters that the exclusion provided for airport mobile refuelers should be extended to mobile refuelers at other types of facilities. The Agency agrees that providing sized secondary containment for vehicles that move frequently within a non- transportation-related facility to perform refueling operations can raise safety and security concerns, so the exclusion from complying with the sized secondary containment requirements provided for airport mobile refuelers is being extended to mobile refuelers that are vehicles with an onboard bulk storage container used to store and transport oil for transfer into or from other vehicles, ground service equipment or another oil storage container.

      Furthermore, the Agency continues to believe that other mobile/ portable bulk storage tanks that are being towed by vehicles or otherwise moved to or from a designated area typically cannot be provided with sized secondary containment as per Sec. Sec. 112.8(c)(2) and (11) and 112.12(c)(2) and (11), as applicable, during that movement or relocation. However, when these mobile/portable bulk storage containers (except mobile refuelers) are placed in a designated area of a site (e.g., a construction site) whereby a dike or catchment basin sufficient to contain the capacity of the largest single compartment or container with sufficient freeboard to contain precipitation can be installed, sized secondary containment requirements would apply. In the same vein, the Agency believes that rail cars cannot be provided with sized secondary containment when entering, moving within, or exiting the confines of a facility. Conversely, when they are situated in defined locations at an otherwise regulated facility, sized secondary containment, such as a catchment basin, could be provided. See Chapter 4 of the SPCC Guidance for Regional Inspectors for further explanation regarding when sized secondary containment is required for mobile or portable containers that are in a stationary, unattended mode. 1. Definition of Mobile Refueler

      EPA is amending the SPCC rule to exempt mobile refuelers from the requirements of Sec. Sec. 112.8(c)(2) and (11) and 112.12(c)(2) and (11). In today's final rule, EPA defines a mobile refueler as ``a bulk storage container, onboard a vehicle or towed, that is designed or used solely to store and transport fuel for transfer into or from an aircraft, motor vehicle, locomotive, vessel, ground service equipment, or other oil storage container.'' The definition is intended to describe vehicles of various sizes equipped with a bulk storage container such as a cargo tank or tank truck that is used to fuel or defuel aircraft, motor vehicles, locomotives, tanks, vessels or other oil storage containers. The definition is also intended to describe tank full trailers and tank semi-trailers including those at airports that are used to fuel or defuel aircraft. The definition does not include other mobile or portable oil storage containers that are not involved in fueling activities. When these other mobile or portable containers are in a stationary, unattended mode and not under the direct oversight or control of facility personnel, the requirements of Sec. Sec. 112.8(c)(2) and (11) and 112.12(c)(2) and (11) apply. (See Chapter 4 of the SPCC Guidance for Regional Inspectors.) In addition, the Agency intends the secondary containment exemption to apply to vehicles used for refueling, and not vehicles used primarily for the bulk storage of oil in a stationary location, in place of stationary oil storage containers.

      A commenter from the aviation sector supported EPA's proposed definition and encouraged the inclusion of fuel transfers into or from ground service equipment. Two commenters from the chemical manufacturing sector stated that the definition that was proposed is too broad and unlawfully extends EPA's

      [[Page 77285]]

      jurisdiction. The MOU between DOT and EPA establishes non- transportation facilities to include ``highway vehicles and railroad cars which are used for the transport of oil exclusively within the confines of a non-transportation-related facility and which are not intended to transport oil in interstate or intrastate commerce.'' EPA understands that mobile refuelers that operate solely within the confines of an airport, or other type of facility that is subject to SPCC regulations would be covered by the definition of mobile refuelers at Sec. 112.2. Thus, a mobile refueler that operates solely on airport property, or some other type of facility would be subject to Sec. 112.7(c) during all periods of operation. Conversely, for a mobile refueler that operates on highways (i.e., intended to transport oil in interstate or intrastate commerce) in addition to an airport, or other type of facility, then only the period of actual transfer operations at a non-transportation facility would be subject to the general secondary containment requirements of Sec. 112.7(c), unless the transfer occurs at a loading/unloading rack, whereby the rack and vehicle are subject to the requirements at Sec. 112.7(h).

      Similarly, another commenter suggested applying the existing requirements for portable fueling facility requirements of Sec. 112.3(c) to mobile refuelers when in a fixed, non-transportation mode. Specific requirements for mobile facilities should be developed as a separate subpart through rulemaking. The Agency disagrees that a separate rulemaking be initiated for mobile refuelers. We believe that the modification being promulgated today provides the owner or operator with considerable flexibility to identify the appropriate spill prevention measures under Sec. 112.7(c) applicable to the mobile refueler operation operating solely at a non-transportation facility. Furthermore, we disagree that Sec. 112.3(c) needs to be modified to apply to this type of mobile refueler that enters a non-transportation facility as this provision already addresses a portable fueling facility operating in a fixed, non-transportation-related mode. For either type of mobile refueler, Sec. 112.7(c) applies. 2. Amended Requirements

      This amendment revises Sec. Sec. 112.8(c)(2) and (11) and 112.12(c)(2) and (11) to specifically exempt mobile refuelers, as defined above, from these provisions. As noted above, the Agency is expanding the proposed exemption from the sized secondary containment requirements to apply to any person that operates a mobile refueler. Since mobile refuelers are mobile or portable bulk storage containers, the other provisions of Sec. Sec. 112.8(c) and 112.12(c) still apply. Secondary containment systems sufficient to contain the capacity of the largest single compartment or container with sufficient freeboard to contain precipitation are no longer required. A commenter representing small business expressed concerns about the security, safety and logistical concerns for the proposed amendment for airport mobile refuelers. The commenter recommended that EPA further revise the SPCC requirements so that general secondary containment applies only when airport mobile refuelers are transferring fuel. The Agency disagrees that the amendment should be limited to transfer operations only, as another commenter asserts that mobile refuelers can experience leaks and spills (e.g., vehicular accidents, line leaks, or other equipment/ container failure). Thus, we believe that the general secondary containment provisions at Sec. 112.7(c) should apply to all mobile refueler operations.

      Per Sec. 112.7(c), appropriate containment and/or diversionary structures or equipment must be designed to prevent a discharge as described in Sec. 112.1(b). The Agency believes general secondary containment should be designed to address the most likely discharge from the primary containment system (i.e., the storage container). Section 112.7(c) allows for the use of certain types of active containment measures (countermeasures or spill response capability) which prevent a discharge to navigable waters or adjoining shorelines. One aviation commenter indicated that the availability of ``active measures'' is necessary to make the general secondary containment provision workable in an airport setting. To clarify, EPA believes that active containment measures are those that require deployment or other specific action by the owner or operator. These measures may be deployed either before an activity involving the handling of oil starts, or in reaction to a discharge, so long as the active measure is designed and can reasonably be implemented to prevent an oil spill from reaching navigable waters or adjoining shorelines. Passive measures are permanent installations and do not require deployment or action by the owner or operator. The efficacy of active containment measures to prevent a discharge depends on their technical effectiveness (i.e., mode of operation, absorption rate), placement and quantity, and timely deployment prior to, or following a discharge. For discharges that occur only during manned activities, such as those occurring during transfers, an active measure (i.e., sock, mat, other portable barrier, or land-based response capability) may be appropriate, provided that the measure is capable of containing the oil discharge volume and rate, and is timely and properly constructed/deployed. The Agency also believes that these active measures may be appropriately applied to other situations (i.e., when the refueler is not engaged in transfer operations or moving around the facility).

      In summary, EPA believes that the general provisions for secondary containment address the most likely spill scenarios associated with this equipment (i.e., during oil transfers into or from the mobile refuelers). Section 112.7(c) does not prescribe a size for a secondary containment structure, but does require appropriate containment and/or diversionary structures or equipment to prevent a discharge as described in Sec. 112.1(b) including the use of active measures. This final rule would maintain environmental protection, while still allowing the necessary flexibility for compliance with the general secondary containment requirements of the rule for mobile refuelers at airports or other types of facilities.

    6. Animal Fats and Vegetable Oils

      The Agency proposed to amend Subpart C of part 112 by removing Sec. 112.13 (requirements for onshore oil production facilities), Sec. 112.14 (requirements for onshore oil drilling and workover facilities), and Sec. 112.15 (requirements for offshore oil drilling, production, or workover facilities) and by reserving these sections of Subpart C of the regulation because they are not appropriate for animal fats and vegetable oils. Commenters generally supported this proposal and therefore, the Agency has amended the final rule to remove these provisions. In addition, the Agency also requested comment on whether different requirements were appropriate for animal fats and vegetable oils from the requirements for petroleum and other oils. Some commenters provided suggestions for differentiating animal fats and vegetable oils from other classes of oils in the SPCC rule. The Agency is continuing to examine these issues to determine the appropriateness of amendments to the regulatory scheme to differentiate the SPCC requirements for animal fats and vegetable oils from the requirements for petroleum and other oils and plans to

      [[Page 77286]]

      address this issue in a future rulemaking.

      As a point of clarification, EPA also removed the phrase ``for onshore facilities (excluding production facilities)'' from the title of Sec. 112.12 Spill Prevention, Control, and Countermeasure Plan requirements. Section 112.2 of the rule defines production facility to mean ``all structures (including, but not limited to, wells, platforms, or storage facilities), piping (including, but not limited to flowlines or gathering lines), or equipment (including, but not limited to workover equipment, separation equipment, or auxiliary non- transportation-related equipment) used in the production, extraction, recovery, lifting, stabilization, separation or treating of oil, or associated storage or measurement, and located in a single geographical oil or gas field operated by a single operator.'' The exclusion of production facilities from Sec. 112.12 was originally intended to differentiate requirements based on facility type and Sec. 112.13 applied to onshore production facilities. Since this final rule removes the inapplicable requirements for animal fats and vegetable oils, it is no longer necessary to differentiate onshore oil production facilities from other facilities in Sec. 112.12.

      As an editorial change, EPA revised the provisions in Sec. 112.7(a)(2) and 112.7(d) to eliminate reference to the inapplicable provisions in Sec. Sec. 112.13 and 112.14, because these sections have been removed.

    7. Extension of Compliance Dates for Farm

      While determining if the agriculture sector warrants specific consideration under the SPCC rule, EPA proposed to extend the compliance dates for preparing or amending and implementing SPCC Plans for farms that have a total storage capacity of 10,000 gallons of oil or less either indefinitely or until the Agency publishes a final rule in the Federal Register establishing a new compliance date. This final rule provides an extension for all farms as defined in this notice until the Agency promulgates a rule specifically addressing how farms should be regulated under the SPCC rules. 1. Eligibility Criteria

      Most commenters, primarily from the agricultural sector, generally supported EPA's proposed extension of compliance for farms with a storage capacity of 10,000 gallons of oil or less. Several commenters who supported the extension suggested modifications to the extension as proposed, such as expanding the extension to all farms. Supporters argued the proposal reduces unnecessary regulatory burden on the agricultural community, while the Agency determines if this sector warrants specific consideration under the SPCC rule. Others argued that the sector is already regulated by state and local agencies for pollution-related activities on farms. Support for the argument that the physical layout of a farm makes this sector unique within the universe of SPCC-regulated facilities was also offered. Comments also were offered in opposition to the extension and potential exemptions from SPCC requirements for farms. Commenters argued that farms may endanger the environment, farmers, and their neighbors and expressed concern that farms are often close to surface waters. Commenters opposing the extension also argued that farms should have been in compliance with the original SPCC rule and that current technology makes compliance relatively inexpensive and easy.

      In finalizing the compliance extension for farms, EPA is adopting the definition of ``farm,'' as proposed, for purposes of part 112 and the extension in the final rule. EPA defines ``farm,'' in part, by adapting the definition used by the National Agricultural Statistics Service (NASS) in its Census of Agriculture. NASS defines a farm as any place from which $1,000 or more of agricultural products were produced and sold, or normally would have been sold, during the census year. Operations receiving $1,000 or more in Federal government payments are counted as farms, even if they have no sales and otherwise lack the potential to have $1,000 or more in sales.

      EPA also considered the definition it uses to exempt farm tanks under the Underground Storage Tank (UST) regulations at 40 CFR part 280. As defined in 40 CFR 280.12, a farm tank is a tank located on a tract of land devoted to the production of crops or raising of animals, including fish. The preamble to the UST rule explains that the term ``farm'' includes fish hatcheries, rangeland, and nurseries with growing operations, but does not include laboratories where animals are raised, land used to grow timber, and pesticide aviation operations. This term also does not include retail stores or garden centers where the product of nursery farms is marketed, but not produced, nor does the Agency interpret the term ``farm'' to include golf courses or other places dedicated primarily to recreational, aesthetic, or other non- agricultural activities. (See 53 FR 37082, 37117, September 23, 1988.) EPA utilized elements of the UST definition of farm, in combination with the Census definition, in developing the proposal and final rule. By combining elements of both of these approaches, the Agency believes the definition more specifically targets the intended universe for the extension.

      Several commenters provided general remarks on definitions of facility, farm, farming facility, farming operation, and/or agribusiness for purposes of the SPCC rule; some proposed alternate definitions of farm. One suggested alternative was to use the definition of eligible agricultural businesses used in the ``Agricultural Business Security Tax Credit Act of 2005'' (S. 052). Most broadly, the term ``eligible agricultural business'' means any person in the trade or business of: selling agricultural products, including specified agricultural chemicals, at retail predominantly to farmers and ranchers, or manufacturing, formulating, distributing, or aerially applying specified agricultural chemicals. The Agency disagrees with expanding the definition as suggested because we believe it would apply to businesses that are distinctly different from farms, e.g., oil marketing and distribution to farmers, that do not present the same unique issues that farms raise. In fact, these agribusinesses are more like industrial or manufacturing operations and thus, it would be inappropriate to include these businesses within the compliance extension. Several commenters suggested that the farm definition specify that operations comprised of non-contiguous or non-adjacent agricultural lands would not be considered a single ``farm facility'' for purposes of fuel tank storage capacity regardless of whether such parcels of land are under common ownership or control. They also suggested that the Agency allow for aggregate tank storage capacity to be determined separately for each field or parcel of such agricultural lands. The definition of facility as provided in Sec. 112.2 currently provides the flexibility for the owner or operator of a farm to determine the scope of his or her facility as recommended by the commenters. However, the Agency will further explore these questions in a future rulemaking addressing farms.

      The Agency is also expanding the extension to owners and operators of all facilities that meet the definition of farm finalized in today's rule, which was supported by many of the commenters. This action allows the Agency to study the universe and determine whether the current requirements are appropriate for farms. The Agency is expanding this extension because, upon further

      [[Page 77287]]

      assessment, we believe it is premature for the Agency to determine that the current SPCC requirements are appropriate for farms with oil storage capacities greater than 10,000 gallons before we undertake our study of the universe of farms. 2. Compliance Date Extension for Farms

      With today's action, EPA extends the compliance dates for the owner or operator of a farm, as defined in Sec. 112.2, to prepare or amend and implement the farm's SPCC Plan until the effective date of a rule addressing whether to provide differentiated requirements for farms. The Agency will announce the new compliance date in the Federal Register. The Agency will be conducting additional information collection and analysis to determine if differentiated SPCC requirements may be appropriate for farms. The Agency will be working with USDA to collect data that would more accurately characterize oil handling at these facilities, thereby allowing the Agency to focus on priorities where substantial environmental improvements can be obtained.

      Some commenters argued that EPA should provide a suspension of requirements rather than an extension of the compliance date. We believe that providing a compliance extension in the same manner as previous compliance extensions that have been granted is appropriate. We are not aware that the farming community has had concerns with the previous compliance extensions that have been granted. In addition, we would have concerns about the impact that such an action may have as some number of farms handle significant quantities of oil and it would not be appropriate to issue a blanket suspension of all spill prevention requirements for owners and operators of these facilities. By extending the compliance date, the Agency is allowing for burden relief, while it makes a determination of whether the agriculture sector warrants specific consideration under the SPCC rule. Regardless of whether the Agency ultimately determines that differentiated requirements for farms are warranted, we will publish a notice in the Federal Register proposing new compliance dates for farms.

  8. Statutory and Executive Order Reviews

    1. Executive Order 12866--Regulatory Planning and Review

      Under section 3(f)(1) of Executive Order (EO) 12866 (58 FR 51735, October 4, 1993), this action is an ``economically significant regulatory action'' because it is likely to have an annual effect on the economy of $100 million or more. Accordingly, EPA submitted this action to the Office of Management and Budget (OMB) for review under EO 12866 and any changes made in response to OMB recommendations have been documented in the docket for this action.

      In addition, EPA prepared an analysis of the potential costs and benefits associated with this action. This analysis is contained in the ``Regulatory Impact Analysis for the Final Revisions to the Oil Pollution Prevention Regulations'' (October 2006). A copy of the analysis is available in the docket for this action and the analysis is briefly summarized here.

      The regulatory impact analysis developed in support of today's action compares the compliance costs for owners and operators of facilities affected by the 2006 amendments to the costs owners and operators would face under the SPCC rule as amended in 2002 with respect to the four major components of the final rule: (1) Qualified facilities with 10,000 gallons or less of storage capacity; (2) facilities with certain types of oil-filled operational equipment; (3) facilities with motive power containers; and (4) facilities with mobile refuelers.

      For each of these components, the benefits consist of reductions in costs accruing from reductions in compliance costs. The main steps used to estimate the compliance cost impacts of the SPCC final Rule are as follows:

      Develop the baseline universe of SPCC-regulated facilities;

      Estimate the number of facilities affected by the final rule amendments;

      Estimate changes in compliance cost elements resulting from the final rule;

      Estimate total compliance cost savings to owners and operators of potentially affected facilities; and

      Annualize compliance cost savings over a ten-year period, 2008 through 2017, and discount the estimates using 3 and 7 percent discount rates.

      Based on these procedures, EPA estimated the average annual number of potentially affected facilities and the annual compliance cost savings associated with each of the four major components of the final rule, as can be seen in Exhibit 1. EPA assumes cost minimization behavior applies to all owners and operators of facilities that qualify for reduced regulatory requirements, whereby all those affected will seek burden relief. These estimates are not necessarily additive, given that they do not account for interactions among the various components of the final rule. Exhibit 1 presents one compliance cost savings scenario for each rule component, whereby all qualified facilities, 50 percent of qualified oil-filled operational equipment, 10 percent of motive power containers, and 50 percent of mobile refuelers are affected.

      \1\ The number of existing facilities with qualified oil-filled operational equipment and mobile refuelers is zero because EPA assumed that existing SPCC-regulated facilities would already have secondary containment or a determination of the impracticability of secondary containment in accordance with Sec. 112.7(d).

      EPA also prepared an Alternative Baseline that describes the estimated changes in cost savings resulting from the 2006 SPCC final rule assuming partial (50 percent) compliance. For this alternative analysis, EPA assumed 50 percent compliance with both the 2002 and 2006 rules. The Agency anticipates the compliance rate under the 2006 final

      [[Page 77288]]

      rule to be at the same level as it would have been under the 2002 rule, or higher.

    2. Paperwork Reduction Act

      The information collection requirements for the final rule were submitted for approval to the Office of Management and Budget (OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The Information Collection Request (ICR) document prepared by EPA has been assigned EPA ICR number 0328.13.

      EPA does not collect the information required by the SPCC rule on a routine basis. SPCC Plans ordinarily need not be submitted to EPA, but must generally be maintained at the facility. Preparation, implementation, and maintenance of an SPCC Plan by the facility owner or operator helps prevent oil discharges, and mitigates the environmental damage caused by such discharges. Therefore, the primary user of the data is the facility personnel. While EPA may, from time to time, request information under these regulations, such requests are not routine.

      Although facility personnel are the primary data user, EPA also uses the data in certain situations. EPA reviews SPCC Plans: (1) When it requests a facility owner or operator to submit required information in the event of certain discharges of oil or to evaluate an extension request; and, (2) as part of EPA's inspection program. State and local governments also use the data, which are not necessarily available elsewhere and can greatly assist local emergency preparedness efforts. Preparation of the information for affected facilities is required under section 311(j)(1) of the Act as implemented by 40 CFR part 112.

      EPA estimates that in the absence of this rulemaking, approximately 580,000 facilities would be subject to the SPCC rule in 2006 and have SPCC Plans. In addition, EPA estimates that approximately 17,500 new facilities would become subject to SPCC requirements annually. In the absence of this final rulemaking, EPA projects that the average annual public reporting and recordkeeping burden for this information collection would be 2,695,329 hours.

      Under today's rulemaking, owners and operators of qualified facilities no longer need a licensed Professional Engineer to certify their Plans. Facilities that store oil solely in motive power containers are no longer regulated, while owners and operators of facilities with oil storage in addition to motive power containers may incur lower compliance costs. Today's rule also allows greater use of contingency plans and written commitment of manpower, equipment, and resources without requiring an impracticability determination when combined with an inspection or monitoring program as an alternative to secondary containment for qualified oil-filled operational equipment. It also allows mobile refuelers at airports and facilities within other industries, to fall under a facility's general secondary containment requirements, rather than require specifically sized secondary containment.

      Under today's rule, an estimated 434,000 regulated facilities would annually be subject to the SPCC information collection requirements of this rule during the information collection period. This figure excludes farms, to reflect the final compliance extension. Under this rule, the estimated annual average burden over the next three-year ICR period would be approximately 2,191,069 hours, resulting in a 19 percent average reduction. The estimated average annual public reporting for owners and operators of individual facilities already regulated under the SPCC rule would range between 3.3 and 7.1 hours, while the burden for owners and operators of newly regulated facilities would range between 40.1 and 70.1 hours as a result of this final action. The net annualized capital and start-up costs for the SPCC information collection portion of the rule would average $1.4 million and net annualized operation and maintenance (O&M) costs are estimated to be $34.3 million for owners and operators of all of these facilities combined.

      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.

    3. 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 final rule on small entities, small entity is defined as: (1) a small business as defined in the SBA's 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, which constitute a large percentage of the facilities affected by this final rule, 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, I certify 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 final 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 reduces regulatory burden on owners and operators of qualified facilities and facilities with qualified oil-filled operational equipment. Owners and operators of qualified facilities no longer need a licensed

      [[Page 77289]]

      Professional Engineer to certify their Plans. Facilities that store oil solely in motive power containers are no longer regulated, while owners and operators of facilities with oil storage in addition to motive power containers may incur lower compliance costs. Today's rule also allows greater use of contingency plans and a written commitment of manpower, equipment, and materials without requiring an impracticability determination as an alternative to secondary containment for qualified oil-filled operational equipment when combined with an established and documented inspection or monitoring program. It also allows mobile refuelers no matter the industry to fall under a facility's general secondary containment requirements rather than require specifically sized secondary containment. The Agency has therefore concluded that today's rule relieves regulatory burden for small entities.

      Overall, EPA estimates that today's rule will reduce annual compliance costs by roughly $38 million for owners and operators of qualified facilities, $53 million for owners and operators of facilities with qualified oil-filled equipment, $1 million for owners and operators of facilities with motive power containers, and $34 million for owners and operators of facilities with mobile refuelers. Total costs were annualized over a 10-year period using both 3 and 7 percent discount rates assuming all qualified facilities, 50 percent of qualified oil-filled operational equipment, 10 percent of motive power containers, and 50 percent of mobile refuelers are affected under this scenario. EPA derived these savings by estimating the number of facilities affected by each provision in the final rule; identifying the specific behavioral changes (e.g., choosing to self-certify an SPCC Plan rather than using a licensed PE) that may occur; estimating the unit costs of compliance measures under the baseline and regulatory scenarios; and applying the change in unit costs to the projected number of affected facilities.

      We have therefore concluded that today's final rule will relieve regulatory burden for all affected small entities.

    4. 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 final 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. Today's final rule would reduce compliance costs on owners and operators of affected facilities by as much as $126 million annually, although EPA acknowledges this estimate is derived from analyses of each of the four major components of the final rule and are not necessarily additive, given that they do not account for interactions among the various components. Thus, today's rule is not subject to the requirements of sections 202 and 205 of the UMRA.

      EPA has determined that this rule contains no regulatory requirements that might significantly or uniquely affect small governments. As explained above, the effect of final rule would be to reduce burden and costs for owners and operators of qualified regulated facilities, including certain small governments that are subject to the rule.

    5. 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 final rule does not have federalism implications. It would 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 program and recognizes that some States have more stringent requirements. 56 FR 54612 (October 22, 1991). This final rule would not preempt State law or regulations. Thus, Executive Order 13132 does not apply to this final rule.

    6. Executive Order 13175--Consultation and Coordination With Indian Tribal Governments

      Executive Order 13175, entitled ``Consultation and Coordination with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), requires EPA to develop an accountable process to ensure ``meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.'' This final rule does not have tribal implications, as specified in Executive Order 13175. Today's rule would not significantly or uniquely affect communities of Indian trial governments. Thus, Executive Order 13175 does not apply to this rule.

    7. Executive Order 13045--Protection of Children From Environmental Health & Safety Risks

      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

      [[Page 77290]]

      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 final rule is not subject to Executive Order 13045 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.

    8. 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. The overall effect of the rule is to decrease the regulatory burden on facility owners or operators subject to its provisions.

  9. 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, EPA did not consider the use of any voluntary consensus standards.

    1. Congressional Review Act

      The Congressional Review Act, 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. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is a ``major rule'' as defined by 5 U.S.C. 804(2) because it will likely result in an annual effect on the economy of $100 million or more. This rule will be effective February 26, 2007.

      Sec. 112.2 Definitions.

      * * * * *

      Farm means a facility on a tract of land devoted to the production of crops or raising of animals, including fish, which produced and sold, or normally would have produced and sold, $1,000 or more of agricultural products during a year. * * * * *

      Mobile refueler means a bulk storage container onboard a vehicle or towed, that is designed or used solely to store and transport fuel for transfer into or from an aircraft, motor vehicle, locomotive, vessel, ground service equipment, or other oil storage container.

      Motive power container means any onboard bulk storage container used primarily to power the movement of a motor vehicle, or ancillary onboard oil-filled operational equipment. An onboard bulk storage container which is used to store or transfer oil for further distribution is not a motive power container. The definition of motive power container does not include oil drilling or workover equipment, including rigs. * * * * *

      Oil-filled operational equipment means equipment that includes an oil storage container (or multiple containers) in which the oil is present solely to support the function of the apparatus or the device. Oil-filled operational equipment is not considered a bulk storage container, and does not include oil-filled manufacturing equipment (flow-through process). Examples of oil-filled operational equipment include, but are not limited to, hydraulic systems, lubricating systems (e.g., those for pumps, compressors and other rotating equipment, including pumpjack lubrication systems), gear boxes, machining coolant systems, heat transfer systems, transformers, circuit breakers, electrical switches, and other systems containing oil solely to enable the operation of the device.

      (1) Environmental Equivalence. Your Plan may not include alternate methods which provide environmental equivalence pursuant to Sec. 112.7(a)(2), unless each alternate method has been reviewed and certified in writing by a Professional Engineer, as provided in paragraph (d) of this section.

      (2) Impracticability. Your Plan may not include any determinations that secondary containment is impracticable and provisions in lieu of secondary containment pursuant to Sec. 112.7(d), unless each such determination and alternative provision has been reviewed and certified in writing by a Professional Engineer, as provided in paragraph (d) of this section.

      (3) Security (excluding oil production facilities). You must either:

      (i) Comply with the requirements under Sec. 112.7(g); or

      (ii) Describe in your Plan how you secure and control access to the oil handling, processing and storage areas; secure master flow and drain valves; prevent unauthorized access to starter controls on oil pumps; secure out-of-service and loading/unloading connections of oil pipelines; address the appropriateness of security lighting to both prevent acts of vandalism and assist in the discovery of oil discharges.

      (4) Bulk Storage Container Inspections. You must either:

      (i) Comply with the requirements under Sec. 112.8(c)(6) or Sec. 112.12(c)(6), as applicable; or

      (ii) Test/inspect each aboveground container for integrity on a regular schedule and whenever material repairs are made. You must determine, in accordance with industry standards, the appropriate qualifications for personnel performing tests and inspections, the frequency and type of testing and inspections which take into account container size, configuration, and design (such as containers that are: shop built, skid-mounted, elevated, equipped with a liner, double walled, or partially buried). Examples of these integrity tests include, but are not limited to: visual inspection, hydrostatic testing, radiographic testing, ultrasonic testing, acoustic emissions testing, or other systems of non-destructive testing. You must keep comparison records and you must also inspect the container's supports and foundations.
