    II. What is the purpose of this action?

    In this action, we are approving revisions to Regulation No. 7, Section XII, for the control of VOC emissions from oil and gas operations. James B. Martin, the Executive Director of the Colorado Department of Public Health and Environment, submitted these revisions to us on August 3, 2007.

    We previously approved Regulation No. 7, Section XII, on August 19, 2005 (see 70 FR 48652) as part of Denver's Early Action Compact (EAC) SIP for the 8-hour ozone standard. The purpose of the EAC SIP is to prevent exceedances of the 8-hour ozone standard in the Denver EAC area.[1] Due to unanticipated growth of condensate tank emissions in the oil and gas sector, the State determined that the version of Regulation No. 7, Section XII, that we approved in 2005 needed to be revised. The version of Regulation No. 7, Section XII, submitted August 3, 2007 requires a greater level of control of condensate tank emissions in the 8-hour ozone non-attainment area.

    III. What is the State's process to submit these materials to EPA?

    Section 110(k) of the CAA addresses our actions on submissions of SIP revisions. The CAA requires States to observe certain procedural requirements in developing SIP revisions. Section 110(a)(2) of the CAA requires that each SIP revision be adopted by a State after reasonable notice and public hearing. This must occur before a State submits the revision to us.

    The Colorado Air Quality Control Commission (AQCC) held public hearings for the revisions to Regulation No. 7, Section XII, on November 17, 2006, November 18, 2006, and December 17, 2006. The AQCC adopted the revisions on January 5, 2007. The revisions became State effective on March 4, 2007.

    We have evaluated the revisions to Regulation No. 7, Section XII, and have determined that the State met the requirements for reasonable notice and public hearing under section 110(a)(2) of the CAA.

    IV. EPA's Evaluation of the Regulation No. 7, Section XII, Revisions

    Colorado's Regulation No. 7, Section XII, “Volatile Organic Compound Emissions From Oil And Gas Operations,” imposes emission control requirements on oil and gas condensate tanks located in the Denver EAC area, with the majority of affected facilities being located in southern Weld County. Among other things, Regulation No. 7, Section XII, includes definitions; required emission reductions for the high ozone season and rest of the year; numerous recordkeeping requirements for a spreadsheet to determine weekly and other periodic compliance; emission factors used to demonstrate compliance; reporting requirements for certain equipment if a construction or Title V permit is issued by the State; a methodology for approval of alternative emissions control equipment; requirements for gas-processing plants; requirements for controlling emissions from dehydration units; and a methodology for approval to develop testing methods and revised emission factors.

    The condensate tank requirements, along with other requirements applicable to oil and gas operations and natural gas fired reciprocating internal combustion engines, were initially promulgated in March 2004, and later Start Printed Page 8196revised in December 2004. Colorado submitted these requirements to us as a SIP revision, which we approved on August 19, 2005 (see 70 FR 48652). Colorado designed the emission limits in the 2004 revision of Regulation No. 7, Section XII, to achieve total condensate tank VOC emissions in the Denver EAC area during the summer ozone season of no more than 91.3 tons per day (tpd) as of May 1, 2007, and 100.9 tpd as of May 1, 2012. These daily values were relied on to demonstrate attainment of the 8-hour ozone standard in the modeling analysis, as part of the EAC SIP. However, because of unanticipated growth of condensate tank emissions, the State later determined that the emission limits in the 2004 version of Regulation No. 7 would be insufficient to meet these daily emission numbers. The 2007 revisions require a greater level of control of condensate tank emissions within the 8-hour ozone non-attainment area boundary. The State's goal remains to achieve the same daily emission targets for condensate tank VOC emissions.

    We note that the VOC emission reductions that are required by Regulation No. 7, Section XII, are achieved not by specific requirements on each condensate tank, but instead by overall or system-wide emission reductions for each affected company's operations. As stated in Regulation No. 7, Section XII, the requirement to control emissions applies to owners or operators of condensate tanks with a cumulative total of 30 tons per year or more of VOC emissions. In practice, industry has controlled the condensate tank VOC emissions with flares or vapor recovery units, and Regulation No. 7, Section XII, requires these types of emission control devices to achieve 95% control efficiency.

    Revised Regulation No. 7, Section XII, raises the system-wide control requirements for the ozone season from the 47.5% VOC reduction requirement that applied from May 1, 2006, through September 30, 2006, to 75% from May 1 through September 30 of each year from 2007 through 2011. For the period from May 1 through September 30 of each year, beginning with 2012, VOC emissions from condensate tanks must be reduced by 78% from uncontrolled actual emissions. Determination of compliance during the ozone season will be on a weekly basis. For the non-ozone season, the State revised the required reduction of condensate tank VOC emissions from 38% to 60% in 2007, and beginning in 2008, and each year thereafter, VOC emissions between October 1 and April 30 must be reduced by 70% from uncontrolled actual emissions. Emission reductions during the non-ozone season must be calculated as an average of the emission reductions achieved during this seven-month period.

    In addition to the changes to the system-wide reduction requirements, the State adopted significant changes to the monitoring, recordkeeping, and reporting requirements. Owners or operators of any condensate storage tank that is being controlled under Regulation No. 7, Section XII, must inspect or monitor the control equipment at least weekly. Types of equipment include combustion devices, vapor recovery units, valves, and thief hatches. As noted above, the record-keeping provisions require owners or operators to maintain a spreadsheet to track emission reductions on a weekly basis during the ozone season (May 1 through September 30). In addition to the spreadsheet, owners or operators are required to maintain records of monitoring and inspection activities. The reporting provisions require owners or operators to submit an annual report by April 30 of each year, and also a semi-annual report by November 30 of each year, detailing emission reductions during the preceding year and ozone season, respectively. Finally, provisions have been added to require owners or operators subject to the condensate storage tank reduction requirements to submit a list of all their controlled tanks on April 30 of each year; to notify the State monthly during the ozone season of any change to the list of controlled tanks; and to notify the State monthly of any instance where the air pollution control equipment was not properly functioning and the steps taken to correct the problem. We have reviewed and are approving the revisions to Regulation No. 7, Section XII, “Volatile Organic Compounds From Oil and Gas Operations” because they require greater reductions in emissions and meet the requirements of section 110 of the CAA.

    V. Consideration of Section 110(l) of the CAA

    Section 110(l) of the CAA states that a SIP revision cannot be approved if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress towards attainment of a NAAQS, or any other applicable requirement of the CAA. The revisions to Regulation No. 7, Section XII, will not interfere with attainment, reasonable further progress, or any other applicable requirement of the CAA.

    VI. Final Action

    In this action, EPA is approving the revisions to Regulation No. 7, Section XII, that were submitted on August 3, 2007. The version of Section XII we are approving supersedes and replaces the prior version we approved at 70 FR 48652 (August 19, 2005). EPA is publishing this rule without prior proposal because the Agency views this as a non-controversial amendment and anticipates no adverse comments. However, in the “Proposed Rules” section of today's Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision if adverse comments are filed. This rule will be effective April 14, 2008 without further notice unless the Agency receives adverse comments by March 14, 2008. If the EPA receives adverse comments, EPA will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. EPA will address all public comments in a subsequent final rule based on the proposed rule. The EPA will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.

    VII. Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and, therefore, is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small Start Printed Page 8197governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

    This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it is not economically significant.

    In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

    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 not a “major rule” as defined by 5 U.S.C. 804(2).

    Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by April 14, 2008. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)

    Footnotes

    1.  In April 2004, EPA designated the Denver area (Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas, Jefferson, and parts of Larimer and Weld counties) as non-attainment for the 8-hour ozone standard, but deferred the effective date of the designation based on a commitment from the State of Colorado, the Regional Air Quality Council and others to implement ozone control measures sooner than required by the Clean Air Act. This commitment was contained in the Denver Early Action Compact (EAC). The non-attainment designation for the area became effective November 20, 2007, as a result of a violation for 2005-2007, which triggers requirements for future revisions to the attainment demonstration SIP for the Denver EAC area.
