Federal New Source Review
07/06/21
08/03/21
 For areas designated nonattainment for one or more National Ambient Air Quality Standards (NAAQS), the applicable SIP must include preconstruction review and permitting requirements for new or modified major stationary sources of such nonattainment pollutant(s) under part D of title I of the Act, commonly referred to as Nonattainment New Source Review (NNSR). The rule listed in Table 1 contains the District's NNSR permit program applicable to new and modified major sources located in areas designated nonattainment for the 1997 and 2015 ozone NAAQS. On February 3, 2022, the submittal for Rule 429 was deemed by operation of law to meet the completeness criteria in 40 CFR part 51 Appendix V, which must be met before formal EPA review. B. Are there other versions of this rule? There are no previous versions of Rule 429 in the SIP. C. What is the purpose of the submitted rule? Rule 429 is intended to address the CAA's statutory and regulatory requirements for NNSR permit programs for major sources emitting nonattainment air pollutants and their precursors. II. The EPA's Evaluation A. What is the background for this proposal? The EPA's April 2004 designation of Tuolumne County as a nonattainment area for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) triggered the requirement for the District to develop and submit an NNSR program to the EPA for SIP approval.[1]
                    
                     Although the EPA revoked the 1997 8-hour ozone NAAQS effective April 6, 2015,[2]
                    
                     the NNSR requirements applicable to Tuolumne County based on its designation and classification for the revoked 1997 8-hour ozone NAAQS remain applicable in order to prevent future emissions from new and modified major stationary sources from increasing beyond the levels allowed, based on the area's prior designation and classification for the 1997 ozone NAAQS. Thus, because Tuolumne County was designated and classified as Moderate nonattainment for the 1997 8-hour ozone NAAQS, the District's NNSR program must satisfy the NNSR requirements applicable to Moderate ozone nonattainment areas, including the offset ratios identified in CAA section 182(b)(5).[3]
                    
                     Tuolumne County is also designated and classified as Marginal nonattainment for the 2015 8-hour ozone NAAQS and, therefore, subject to the NNSR requirements applicable to Marginal ozone nonattainment areas.[4]
                    
                     Submission of an NNSR program that satisfies the requirements of the Act and the EPA's regulations for Moderate ozone nonattainment areas, however, would satisfy the NNSR program requirements for Marginal ozone nonattainment areas.[5] Additional information regarding the District's nonattainment status for each pollutant is included in our Technical Support Document (TSD), which may be found in the docket for this rule. B. How is the EPA evaluating the rule? The EPA reviewed Rule 429 for compliance with CAA requirements for: (1) stationary source preconstruction permitting programs as set forth in CAA part D, including CAA sections 172(c)(5) and 173; (2) the review and modification of major sources in accordance with 40 CFR 51.160-51.165 as applicable in Moderate ozone nonattainment areas; (3) the review of new major stationary sources or major modifications in a designated nonattainment area that may have an 
                    ( print page 42134)
                    impact on visibility in any mandatory Class I Federal Area in accordance with 40 CFR 51.307; (4) SIPs in general as set forth in CAA section 110(a)(2), including 110(a)(2)(A) and 110(a)(2)(E)(i); [6]
                    
                     and (5) SIP revisions as set forth in CAA section 110(l) and 193.[7 8]
                     Our review evaluated the submittal for compliance with the NNSR requirements applicable to Moderate ozone nonattainment areas, and ensured that the submittal addressed the NNSR requirements for the 1997 and 2015 ozone NAAQS. C. Does the rule meet the evaluation criteria? With respect to procedural requirements, CAA sections 110(a)(2) and 110(l) require that revisions to a SIP be adopted by the state after reasonable notice and public hearing. Based on our review of the public process documentation included in the August 3, 2021 submittal of Rule 429, we find that the District has provided sufficient evidence of public notice, opportunity for comment, and a public hearing prior to adoption and submittal of these rules to the EPA. With respect to the substantive requirements found in CAA sections 172(c)(5) and 173, and 40 CFR 51.160-51.165, we have evaluated Rule 429 in accordance with the applicable CAA and regulatory requirements that apply to NNSR permit programs under part D of title I of the Act for all relevant ozone NAAQS, including the 2015 ozone NAAQS. We find that Rule 429 satisfies these requirements as they apply to sources subject to the NNSR permit program requirements applicable to Moderate ozone nonattainment areas. We have also determined that this rule satisfies the related visibility requirements in 40 CFR 51.307. In addition, we have determined that Rule 429 satisfies the requirement in CAA section 110(a)(2)(A) that requires regulations submitted to the EPA for SIP approval be clear and legally enforceable, and we have determined that the submittal demonstrates, in accordance with CAA section 110(a)(2)(E)(i), that the District has adequate personnel, funding, and authority under state law to carry out these proposed SIP revisions. Regarding the additional substantive requirements of CAA sections 110(l) and 193, our action will result in a more stringent SIP, while not relaxing any existing provision contained in the SIP. We have concluded that our action would comply with section 110(l) because our approval of Rule 429 will not interfere with any applicable requirement concerning attainment and reasonable further progress, or any other CAA applicable requirement. In addition, our approval of Rule 429 will not relax any pre-November 15, 1990 requirement in the SIP, and therefore changes to the SIP resulting from this action ensure greater or equivalent emission reductions of ozone and its precursors in the District. Accordingly, we have concluded that our action is consistent with the requirements of CAA section 193. III. Proposed Action and Public Comment As authorized in sections 110(k)(3) and 301(a) of the Act, the EPA is proposing to approve the submitted rule because it fulfills the relevant CAA requirements, and strengthens the SIP. We have concluded that our approval of the submitted rule would comply with the relevant provisions of CAA sections 110(a)(2), 110(l), 172(c)(5), 173, and 193, 40 CFR 51.160-51.165, and 40 CFR 51.307. If finalized as proposed, our action will be codified through revisions to 40 CFR 52.220 (Identification of plan-in part). In conjunction with the EPA's SIP approval of the District's visibility provisions for sources subject to the NNSR program as meeting the relevant requirements of 40 CFR 51.307, this action would also revise the regulatory provision at 40 CFR 52.281(d) concerning the applicability of the visibility Federal Implementation Plan (FIP) at 40 CFR 52.28 as it pertains to California, to provide that this FIP does not apply to sources subject to review under the District's SIP-approved NNSR program. We will accept comments from the public on this proposal until August 15, 2022. IV. Incorporation by Reference In this rule, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference the District rule described in Section I.A. of this preamble. The EPA has made, and will continue to make, these materials available through 
                    *www.regulations.gov*
                     and in hard copy at the EPA Region IX Office (please contact the person identified in the 
                    **FOR FURTHER INFORMATION CONTACT**
                     section of this preamble for more information). V. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this proposed action merely proposes to approve state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action: Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
                Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 
                    *et seq.*);
                Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 
                    *et seq.*);
                Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
                Does not have federalism implications as specified inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
                Is not a significant regulatory action subject toExecutive Order 13211 (66 FR 28355, May 22, 2001);
                Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
                Does not provide the EPA with the discretionary authority to address( print page 42135)
                    disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
