[Federal Register Volume 61, Number 174 (Friday, September 6, 1996)] [Rules and Regulations] [Pages 47058-47060] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 96-22645] ----------------------------------------------------------------------- ENVIRONMENTAL PROTECTION AGENCY 40 CFR Parts 52 and 81 [FRL-5560-4] Approval and Promulgation of Implementation Plans; Designation of Areas for Air Quality Planning Purposes; Wyoming; Corrections AGENCY: Environmental Protection Agency (EPA). ACTION: Direct final rulemaking. ----------------------------------------------------------------------- SUMMARY: EPA is promulgating corrections to the State Implementation Plan (SIP) for the State of Wyoming regarding the State's ambient standards for fluorides and hydrogen sulfide and the State's odor control regulation. EPA has determined that these rules were erroneously incorporated into the SIP. EPA is removing these rules from the approved Wyoming SIP because the rules do not have a reasonable connection to the national ambient air quality standards (NAAQS) and related air quality goals of the Clean Air Act. The intended effect of this correction to the SIP is to make the SIP consistent with the requirements of the Clean Air Act, as amended in 1990 (``the Act''), regarding EPA action on SIP submittals and SIPs for national primary and secondary ambient air quality standards. In addition, EPA is amending the boundary description for the ``Powder River Basin'' PM-10 unclassifiable area in 40 CFR 81.351. EPA promulgated revisions to 40 CFR 81.351 in a November 3, 1995 rulemaking, and EPA erroneously published an incorrect boundary description for the Powder River Basin area. This document corrects that error. DATES: This action will become effective on November 5, 1996, unless adverse comments are received within 30 days of publication. If the effective date is delayed, timely notice will be published in the Federal Register. ADDRESSES: Copies of the documents relative to this action are available for inspection during normal business hours at the following location: Air Program, Environmental Protection Agency, Region VIII, 999 18th Street, Suite 500, Denver, Colorado 80202-2466. FOR FURTHER INFORMATION CONTACT: Vicki Stamper, 8P2-A, Environmental Protection Agency, Region VIII, 999 18th Street, Suite 500, Denver, Colorado 80202-2466, (303) 312-6445. SUPPLEMENTARY INFORMATION: I. Corrections to SIP The Act was first amended in 1970. At this time, a large number of SIPs were submitted to EPA to fulfill the new Federal requirements. In many cases, states and districts submitted their entire programs, including many elements not required pursuant to the Act. Due to resource constraints at that time, EPA's review of these submittals focused primarily on the required technical, legal, and enforcement elements of the submittals. At the time, EPA did not perform a detailed review of the numerous provisions submitted, to determine if each provision was related to protection of the NAAQS. Provisions approved as part of states' SIPs should generally be related to attainment and maintenance of the NAAQS, consistent with the authority in section 110 of the Act under which these plans are approved by EPA. During a recent review of the contents of the Wyoming SIP, EPA determined that three provisions of the State's rules were approved as part of the SIP which did not have a reasonable connection to the NAAQS-related air quality goals of the Act. These State rules include the ambient standard for hydrogen sulfide in Section 7 of the Wyoming Air Quality Standards and Regulations (WAQSR), the 1972 version of the ambient standard for fluorides in Section 11 of the WAQSR,1 and the odor control rules in Section 16 of the WAQSR. In addition, documents included in the State's November 19, 1993 title V operating permit program submittal indicated that the State did not consider these three rules part of the federally-approved SIP. EPA consequently notified the State of this discrepancy in a June 26, 1995 letter and offered to correct the SIP pursuant to section 110(k)(6) of the Act by removing these three rules from the SIP, since they are not reasonably connected to the NAAQS-related air quality goals of the Act. The State responded in a letter dated September 19, 1995 requesting that EPA remove these three provisions from the approved SIP. \1\ Section 11 of the WAQSR was amended by the State in 1986, but that version was never submitted to, or approved by, EPA as part of the SIP for Wyoming. --------------------------------------------------------------------------- Section 110(k)(6) of the amended Act provides: Whenever the Administrator determines that the Administrator's action approving, disapproving, or promulgating any plan or plan revision (or part thereof), area designation, redesignation, classification, or reclassification was in error, the Administrator may in the same manner as the approval, disapproval, or promulgation revise such action as appropriate without requiring any further submission from the State. Such determination and the basis thereof shall be provided to the State and public. Since the State of Wyoming's rules for hydrogen sulfide ambient standards, fluoride ambient standards, and odor control have no reasonable connection to the NAAQS-related air quality goals of the Act and since the State has requested that EPA remove these rules from the approved SIP, EPA has found that approval of these State rules was in error. Consequently, EPA is removing Sections 7, 11, and 16 of the WAQSR from the approved Wyoming SIP pursuant to section 110(k)(6) of the Act. II. Correction of Boundary Description for the Powder River Basin Area On November 3, 1995, EPA promulgated revisions to the State of Wyoming's PM-10 area designation table in 40 CFR 81.351 pursuant to the State's adoption and EPA's approval of prevention of significant deterioration (PSD) increments for PM-10 (see 60 FR 55800). In that notice, EPA cited an earlier and incorrect boundary description for the area designated as the ``Powder River Basin'' in Campbell and Converse counties. EPA promulgated a revised boundary description for the Powder River Basin area on September 12, 1995 (60 FR 47299), and that revised boundary [[Page 47059]] should have been reflected in the November 3, 1995 rulemaking. Therefore, this notice corrects the boundary description for the Powder River Basin area to reflect the September 12, 1995 rulemaking. III. Final Action EPA is removing Sections 7, 11, and 16 of the WAQSR from the approved Wyoming SIP pursuant to section 110(k)(6) of the Act. In addition, EPA is correcting the boundary description for the Powder River Basin PM-10 unclassifiable area in 40 CFR 81.351 to reflect the boundary description promulgated for the area on September 12, 1995 (60 FR 47299). The EPA is publishing this action without prior proposal because the Agency views this as a noncontroversial amendment and anticipates no adverse comments. However, in a separate document in this Federal Register publication, EPA is proposing to correct the SIP should adverse or critical comments be filed. Under the procedures established in the May 10, 1994 Federal Register (59 FR 24054), this action will be effective November 5, 1996, unless, by October 7, 1996, adverse or critical comments are received. If such comments are received, this action will be withdrawn before the effective date by publishing a subsequent document that will withdraw the final action. All public comments received will then be addressed in a subsequent final rule based on this action serving as a proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. If no such comments are received, the public is advised that this action will be effective on November 5, 1996. Nothing in this action should be construed as permitting or allowing or establishing a precedent for any future request for revision to any SIP. Each request for revision to a SIP shall be considered separately in light of specific technical, economic, and environmental factors and in relation to relevant statutory and regulatory requirements. IV. Administrative Requirements A. Executive Order 12866 This action has been classified as a Table 3 action for signature by the Regional Administrator under the procedures published in the Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a July 10, 1995 memorandum from Mary Nichols, Assistant Administrator for Air and Radiation. The Office of Management and Budget (OMB) has exempted this regulatory action from E.O. 12866 review. B. Regulatory Flexibility Act Under the Regulatory Flexibility Act, 5 U.S.C. 600, et seq., EPA must prepare a regulatory flexibility analysis assessing the impact of any proposed or final rule on small entities. 5 U.S.C. 603 and 604. Alternatively, EPA may certify that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small not-for-profit enterprises, and government entities with jurisdiction over populations of less than 50,000. This action does not impose any new requirements. Therefore, the Administrator certifies that this action will not have a significant impact on a substantial number of small entities. C. Unfunded Mandates Under section 202 of the Unfunded Mandates Reform Act of 1995 (``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA must prepare a budgetary impact statement to accompany any proposed or final rule that includes a Federal mandate that may result in estimated costs to State, local, or tribal governments in the aggregate; or to the private sector, of $100 million or more. Under section 205, EPA must select the most cost-effective and least burdensome alternative that achieves the objectives of the rule and is consistent with statutory requirements. Section 203 requires EPA to establish a plan for informing and advising any small governments that may be significantly or uniquely impacted by the rule. EPA has determined that this correction action promulgated does not include a Federal mandate that may result in estimated costs of $100 million or more to either State, local, or tribal governments in the aggregate, or to the private sector. This Federal action corrects this state implementation plan, pursuant to section 110(k)(6) of the Act, by removing three State rules that were erroneously incorporated into the SIP. Thus, this action will impose no new requirements. Accordingly, no additional costs to State, local, or tribal governments, or to the private sector, result from this action. D. Submission to Congress and the General Accounting Office Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business Regulatory Enforcement Fairness Act of 1996, EPA submitted 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 General Accounting Office prior to publication of the rule in today's Federal Register. This rule is not a ``major rule'' as defined by 5 U.S.C. 804(2). E. Petitions for Judicial Review 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 November 5, 1996. 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 must 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)).
