SUPPLEMENTARY INFORMATION:  I. Background The WVDEP submitted two SIP revisions to EPA on June 6, 2012 (the 2012 submittal) and on July 1, 2014 (the 2014 submittal). EPA is acting on these two submittals as a whole.[1]
           A summary of all the changes made in each of the submittals has been included in the docket for this action in a document titled, “Summary of West Virginia PSD Changes.” These SIP revision requests, if approved, would revise West Virginia's currently approved PSD program by amending Series 14 under Title 45 of West Virginia Code of State Rules (45CSR14). On May 16, 2008, EPA promulgated a rule to implement the 1997 PM2.5 National Ambient Air Quality Standard (NAAQS), including changes to the New Source Review (NSR) program (the 2008 NSR PM2.5 Rule). *See*73 FR 28321. The ( print page 16613)2008 NSR PM2.5 Rule revised the NSR program requirements to establish the framework for implementing preconstruction permit review for the PM2.5 NAAQS in both attainment and nonattainment areas.[2]
           The 2008 NSR PM2.5 rule: (1) Required NSR permits to address directly emitted PM2.5 and precursor pollutants; (2) established significant emission rates for direct PM2.5 and precursor pollutants (including sulfur dioxide (SO2) and oxides of nitrogen (NOX)); (3) established PM2.5 emission offsets; and (4) required states to account for gases that condense to form particles (condensables) in PM2.5 emission limits.[3] The 2008 NSR PM2.5 Rule (as well as the more general PM2.5 NAAQS implementation rule, the 2007 “Final Clean Air Fine Particle Implementation Rule” (2007 PM2.5 Implementation Rule) [4]

          ), was the subject of litigation before the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit) in *Natural Resources Defense Council* v. *EPA* (hereafter, *NRDC* v. *EPA*).[5]

           On January 4, 2013, the D.C. Circuit remanded to EPA both the 2007 PM2.5 Implementation Rule and the 2008 NSR PM2.5 Rule. The court found that in both rules EPA erred in implementing the 1997 PM2.5 NAAQS solely pursuant to the general implementation provisions of subpart 1 of part D of title I of the CAA (subpart 1), rather than pursuant to the additional implementation provisions specific to particulate matter in subpart 4 of part D of title I (subpart 4).[6]

           As a result, the D.C. Circuit remanded both rules and instructed EPA “to re-promulgate these rules pursuant to subpart 4 consistent with this opinion.” Although the D.C. Circuit declined to establish a deadline for EPA's response, EPA intends to respond promptly to the court's remand and to promulgate new generally applicable implementation regulations for the PM2.5 NAAQS in accordance with the requirements of subpart 4. In the interim, however, states and EPA still need to proceed with implementation of the 1997 PM2.5 NAAQS in a timely and effective fashion in order to meet statutory obligations under the CAA and to assure the protection of public health intended by those NAAQS. In a June 2, 2014 final rulemaking entitled “Identification of Nonattainment Classification and Deadlines for Submission of State Implementation Plan (SIP) Provisions for the 1997 Fine Particle (PM2.5) National Ambient Air Quality Standard (NAAQS) and 2006 PM2.5 NAAQS; Final Rule,” (79 FR 31566), EPA identified the classification status under subpart 4 for areas currently designated nonattainment for the 1997 and 2006 PM2.5 NAAQS.[7] As the requirements of Subpart 4 only pertain to nonattainment areas, EPA does not consider the portions of the 2008 NSR PM2.5 Rule that address requirements for PM2.5 attainment and unclassifiable areas to be affected by the *NRDC* v. *EPA* opinion. Moreover, EPA does not anticipate the need to revise any PSD permitting requirements promulgated in the 2008 NSR PM2.5 Rule in order to comply with the D.C. Circuit's decision. This proposed rulemaking addresses West Virginia's PSD regulations. Thus, EPA has evaluated the regulations with applicable PSD requirements in the CAA, its implementing regulations, and the 2008 NSR PM2.5 Rule. The CAA's PSD provisions also establish maximum allowable increases over baseline concentrations—also known as “increments”—for certain pollutants. EPA has the task of promulgating regulations to prevent the significant deterioration of air quality that would result from the emissions of pollutants EPA began regulating after Congress enacted the PSD provisions in the CAA, which includes PM2.5. The PSD provisions establish preconstruction review and permitting of new or modified sources of air pollution. In 2007, EPA proposed a rule establishing increments for PM2.5 and also proposed two screening tools that would exempt permit applicants from some air quality analysis and monitoring required for PSD: Significant impact levels (SILs) and significant monitoring concentration (SMC). *See*72 FR 54112 (September 21, 2007). In our October 20, 2010 final rule (the PM2.5 PSD Increments-SILs-SMC Rule), EPA set values for both SILs and SMC for PM2.5.*See*75 FR 64864. The Sierra Club challenged EPA's authority to implement PM2.5 SILs and SMC for PSD purposes as promulgated in the PM2.5 PSD Increments-SILs-SMC Rule. *See Sierra Club* v. *EPA,* 705 F.3d 458 (D.C. Cir. 2013). On January 22, 2013, the D.C. Circuit granted a request from EPA to vacate and remand to the Agency the portions of the PM2.5 PSD Increments-SILs-SMC Rule addressing the SILs for PM2.5 (found in paragraph (k)(2) in 40 CFR 51.166 and 52.21), except for the parts codifying the PM2.5 SILs at 40 CFR 51.165(b)(2), so that the EPA could voluntarily correct an error in the provisions. *Id.* at 463-66. The D.C. Circuit also vacated parts of the PSD Increments-SILs-SMC Rule establishing the PM2.5 SMC, finding that the Agency had exceeded its statutory authority with respect to these provisions. *Id.* at 469. In response to the D.C. Circuit's decision, EPA took final action on December 9, 2013 to remove the SIL provisions from the Federal PSD regulations in 40 CFR 52.21 and to revise the SMC for PM2.5 to zero micrograms per cubic meter. *See*78 FR 73698. Because the D.C. Circuit vacated the SMC provisions in 40 CFR 51.166(i)(5)(i)(*c*) and 52.21(i)(5)(i)(*c*), EPA revised the existing concentration for the PM2.5 SMC listed in sections 51.166(i)(5)(i)(*c*) and 52.21(i)(5)(i)(*c*) to zero micrograms per cubic meter. EPA did not entirely remove PM2.5 as a listed pollutant in the SMC provisions because to do so might lead to the issuance of permits that contradict the holding of the D.C. Circuit as to the statutory monitoring requirements. *Id.* (providing EPA's explanation for including the zero micrograms per cubic meter SMC). On May 9, 2013, EPA had disapproved a narrow portion of a SIP revision submitted by the State of West Virginia on August 31, 2011 for revising West Virginia's PSD requirements in 45 CSR14 because the submittal did not satisfy the Federal requirement for inclusion of condensable emissions of PM (condensables) within the definition of “regulated new source review (NSR) pollutant” (at 45CSR14 section 2.66) for PM2.5 and PM emissions less than or equal to ten micrometers in diameter (PM10).[8] 
 
 II. Summary of SIP Revision and EPA Analysis A. Summary of SIP Revision Specifically, the revisions submitted by WVDEP on July 1, 2014 and June 6, 2012 involve amendments to 45CSR14 (Permits for Construction and Major Modification of Major Stationary Sources for the Prevention of Significant Deterioration) based on the Federal regulatory actions discussed above in section I. A summary of the changes made in the 2012 and 2014 submittals are available in the docket in a document titled, “Summary of West Virginia NSR Changes.” Generally, the revisions in the 2012 submittal were submitted to incorporate provisions related to the 2008 NSR PM2.5 Rule. The 2014 submittal revises certain subdivisions of the 2012 submittal as shown in the table below: Rule 45CSR14 subdivision
Description of change2.66.a.1
Added PM condensable emissions to definition of “regulated NSR pollutant”.2.66.a.2
Added language identifying precursors to NAAQS pollutants to the definition of “regulated NSR pollutant”.16.7.c
Deleted 24-hour de minimis air quality impact concentration value for PM2.5 (aka SMC for PM2.5).16.1.a & b
Added provision exempting requirements of 9.1 for stationary sources based on completeness date of permit applications.9.2
Significant Impact Levels. Deleted this provision in its entirety.
 In general, the 2014 submittal adds PM condensable emissions to the definition of “regulated NSR pollutant” and deletes SILs and SMC for PM2.5 in the 45CSR14 provisions submitted for SIP approval. B. EPA Analysis EPA finds the revisions to 45CSR14 contained in the 2012 submittal and the 2014 submittal which were submitted by WVDEP for approval mirror the PSD requirements of the 2008 NSR PM2.5 Rule with certain exceptions described in the next paragraph. The 2014 submittal addresses and corrects the deficiency identified in EPA's May 9, 2013 disapproval (78 FR 27062) by adding language to the provision at 45CSR14 section 2.66.a.1 which now includes PM condensable emissions in the definition of “regulated NSR pollutant.” Thus, EPA finds West Virginia has addressed the deficiency noted in our limited disapproval in 78 FR 27062. However, while the 2014 submittal appropriately removes SILs for PM2.5 consistent with the D.C. Circuit's *Sierra Club* v. *EPA* decision and our final December 9, 2013 rulemaking (78 FR 73698), West Virginia's PSD provision at 45CSR14-16.7.c (included in the 2014 submittal) does not include a SMC value of zero micrograms per cubic meter for PM2.5 consistent with the D.C. Circuit's *Sierra Club* v. *EPA* decision and our December 9, 2013 rulemaking (78 FR 73698) which addressed the D.C. Circuit's vacature of the SMC provisions in 40 CFR parts 51 and 52 for PM2.5. Therefore, West Virginia's PSD regulation, 45CSR14, does not fully meet the requirements for PSD programs as set forth in the 2008 NSR PM2.5 Rule, the D.C. Circuit's decision on SILs and SMC in *Sierra Club* v. *EPA,* and in EPA's December 9, 2013 rulemaking addressing that decision for SILs and SMC. However, on January 20, 2015, West Virginia committed to submitting an additional SIP revision with a revised PSD regulation at 45CSR14-16.7.c which will incorporate a SMC value of zero micrograms per cubic meter for PM2.5 to address this discrepancy. West Virginia committed to submitting this SIP revision no later than one year following the effective date of the final rulemaking notice for conditional approval of the 2012 and the 2014 submittals so that EPA can conditionally approve the 2012 and 2014 submittals.[9]*See* CAA section 110(k)(4). With the exception of the absence of the SMC value of zero micrograms per cubic meter for PM2.5 which WVDEP has committed to address, EPA finds the 2012 and 2014 submittals meet applicable requirements for a PSD permitting program in the CAA, its implementing regulations, and the 2008 NSR PM2.5 Rule. The EPA is soliciting public comments on the issues discussed in this document. Any comments submitted in a timely manner will be considered before taking final action. III. Proposed Action EPA is proposing conditional approval of these West Virginia SIP revisions, the 2012 and 2014 submittals, because West Virginia is committing to submit an additional SIP revision addressing the deficiency identified by EPA regarding the deletion of the PM2.5 SMC within one year of the date of EPA's final conditional approval and because the submittals otherwise meet CAA requirements as discussed in this proposed rulemaking. Once EPA has determined that West Virginia has satisfied this condition, the conditional approval of the 2012 and 2014 submittals will become a full approval. Should West Virginia fail to meet the condition specified above, the conditional approval of the 2012 and 2014 submittals will convert to a disapproval pursuant to CAA section 110(k)(4). The full or partial disapproval of a SIP revision triggers the requirement under CAA section 110(c) that EPA promulgate a federal implementation plan (FIP) no later than two years from the date of the disapproval unless the State corrects the deficiency, and the Administrator approves the plan or plan revision before the Administrator promulgates such FIP. EPA has determined that West Virginia's 2014 submittal has rectified the deficiency regarding including condensables in the definition of regulated NSR pollutant noted in our limited disapproval in 78 FR 27062. Therefore, upon final approval of the 2014 submittal, the EPA is no longer required to promulgate a FIP to address the issue of PM condensables in the definition of regulated NSR pollutant for West Virginia's PSD permit program, and our narrow disapproval of the August 31, 2011 PSD SIP (for failure to include condensables in definition of regulated NSR pollutant) will become a full approval. However, EPA is proposing conditional approval for the 2012 and 2014 submittals due to West Virginia's lack of a PM2.5 SMC with the value of zero micrograms per cubic meter. IV. Incorporation by Reference In this rule, 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 WV regulations at 45CSR14 regarding the Prevention of Significant ( print page 16615)deterioration permitting requirements as discussed in section III of this preamble. The EPA has made, and will continue to make, these documents generally available electronically through *www.regulations.com* and/or in hard copy at the appropriate EPA office (see the **ADDRESSES** 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 CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves 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 underExecutive Order 12866 (58 FR 51735, October 4, 1993);

        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 EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, underExecutive Order 12898 (59 FR 7629, February 16, 1994). In addition, this proposed rule, relating to West Virginia's PSD program, does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
