Environmental Protection Agency (EPA).
Direct final rule.
The Environmental Protection Agency (EPA) is approving a portion of the State Implementation Plan (SIP) revision submitted by Mississippi, through the Mississippi Department of Environmental Quality (MDEQ), Office of Pollution Control, on June 7, 2016. Specifically, this action approves the portion of the SIP revision making changes to Mississippi's Prevention of Significant Deterioration (PSD) program by modifying the incorporation by reference (IBR) date for the Federal PSD regulations promulgated by EPA. By changing this date, approval of the SIP revision modifies the existing Greenhouse Gas (GHG) PSD permitting program and incorporates PSD provisions related to the 1997, 2006, and 2012 fine particulate matter (PM2.5) and 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS). This action is being taken pursuant to the Clean Air Act (CAA or Act) and its implementing regulations.
This direct final rule is effective October 10, 2017 without further notice, unless EPA receives adverse comment by September 7, 2017. If EPA receives such comments, it will publish a timely withdrawal of the direct final rule in the Federal Register and inform the public that the rule will not take effect.

I. What action is the Agency taking?
On June 7, 2016, MDEQ submitted a SIP revision for EPA's approval that includes changes to Mississippi's regulations to make them consistent with Federal requirements for the New Source Review (NSR) permitting program, in particular for PSD permitting.
Additionally, the submittal renames the State's PSD regulations in the SIP from APC-S-5 to Mississippi Administrative Code, Title 11, Part 2, Chapter 5 (hereinafter referred to as Regulation 11-MAC-Part 2-5), and makes formatting changes to these regulations. EPA approved these administrative changes to the PSD regulations in a Letter Notice dated July 20, 2017.
EPA is approving the portion of Mississippi's submittal that makes changes to the State's PSD program, as established in MDEQ's Regulation 11-MAC-Part 2-5, which applies to the construction or modification of any major stationary source in areas designated as attainment or unclassifiable as required by part C of title I of the CAA. This SIP revision is intended to make Mississippi's state PSD permitting rule consistent with the Federal requirements, as promulgated by EPA. The June 7, 2016 submittal updates the IBR date at 11-MAC-Part 2-5 Rule 5.1 and Rule 5.2 from November 4, 2011, to February 17, 2016, for the Federal PSD permitting regulations at 40 CFR 52.21 and 51.166.
By modifying the IBR date of 40 CFR 52.21, Mississippi is making four changes to its PSD rules: (1) Adopting provisions for GHG plantwide applicability limitations (PALs); (2) removing permitting requirements for certain GHG sources; (3) incorporating grandfathering provisions for the 2012 primary annual PM2.5 
NAAQS Start Printed Page 37016and the 2015 8-hour ozone NAAQS; and (4) incorporating a correction to the definition of “regulated NSR pollutant” for PSD.
These changes are discussed below.
A. Greenhouse Gases and Plantwide Applicability Limits
On January 2, 2011, GHG emissions were, for the first time, covered by the PSD and title V operating permit programs.
To establish a process for phasing in the permitting requirements for stationary sources of GHGs under the CAA PSD and title V programs, on June 3, 2010, the EPA published a final rule entitled “Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule” (hereinafter referred to as the GHG Tailoring Rule). See 75 FR 31514. In Step 1 of the GHG Tailoring Rule, which began on January 2, 2011, the EPA limited application of PSD and title V requirements to sources of GHG emissions only if they were subject to PSD or title V “anyway” due to their emissions of pollutants other than GHGs. These sources are referred to as “anyway sources.”
In Step 2 of the GHG Tailoring Rule, which applied as of July 1, 2011, the PSD and title V permitting requirements applied to some sources that were classified as major sources based solely on their GHG emissions or potential to emit GHGs. Step 2 also applied PSD permitting requirements to modifications of otherwise major sources that would increase only GHG emissions above the level in the EPA regulations. EPA generally described the sources covered by PSD during Step 2 of the GHG Tailoring Rule as “Step 2 sources” or “GHG-only sources.”
Subsequently, EPA published the GHG Step 3 Rule on July 12, 2012. See 77 FR 41051. In this rule, EPA decided against further phase-in of the PSD and title V requirements for sources emitting lower levels of GHG emissions. Thus, the thresholds for determining PSD applicability based on emissions of GHGs remained the same as established in Step 2 of the Tailoring Rule.
The GHG PALs portion of the July 12, 2012 final rule revised EPA regulations under 40 CFR part 52 for establishing PALs for GHG emissions. A PAL establishes a site-specific plantwide emission level for a pollutant that allows the source to make changes at the facility without triggering the requirements of the PSD program, provided that emissions do not exceed the PAL level. Under EPA's interpretation of the Federal PAL provisions, such PALs are already available under PSD for non-GHG pollutants and for GHGs on a mass basis. EPA revised the PAL regulations to allow for GHG PALs to be established on a carbon dioxide equivalent (CO2 e) 
basis as well. See 77 FR 41051 (July 12, 2012). EPA finalized these changes in an effort to streamline Federal and SIP PSD permitting programs by allowing sources and permitting authorities to address GHGs using PALs in a manner similar to the use of PALs for non-GHG pollutants.
On June 23, 2014, the U.S. Supreme Court addressed the application of stationary source permitting requirements to GHG emissions in Utility Air Regulatory Group (UARG) v. EPA, 134 S. Ct. 2427 (2014). The Supreme Court upheld EPA's regulation of Step 1—or “anyway” sources—but held that EPA may not treat GHGs as air pollutants for the purposes of determining whether a source is a major source (or a modification thereof) and thus require the source to obtain a PSD or title V permit. Therefore, the Court invalidated PSD and title V permitting requirements for Step 2 sources.
In accordance with the Supreme Court decision, on April 10, 2015, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) issued an Amended Judgment vacating the regulations that implemented Step 2 of the GHG Tailoring Rule, but not the regulations that implement Step 1 of the GHG Tailoring Rule. Coalition for Responsible Regulation, Inc. v. EPA, 606 Fed. Appx. 6, 7 (D.C. Cir. 2015). With respect to Step 2 sources, the D.C. Circuit's Judgment vacated the EPA regulations under review (including 40 CFR 51.166(b)(48)(v) and 40 CFR 52.21(b)(49)(v)) “to the extent they require a stationary source to obtain a PSD permit if greenhouse gases are the only pollutant (i) that the source emits or has the potential to emit above the applicable major source thresholds, or (ii) for which there is a significant emissions increase from a modification.” Id. at 7-8.
EPA promulgated a good cause final rule on August 19, 2015, entitled “Prevention of Significant Deterioration and Title V Permitting for Greenhouse Gases: Removal of Certain Vacated Elements.” See 80 FR 50199 (August 19, 2015) (hereinafter referred to as the Good Cause GHG Rule). The rule removed from the Federal regulations the portions of the PSD permitting provisions for Step 2 sources that were vacated by the D.C. Circuit (i.e., 40 CFR 51.166(b)(48)(v) and 52.21(b)(49)(v)). EPA therefore no longer has the authority to conduct PSD permitting for Step 2 sources, nor can EPA approve provisions submitted by a state for inclusion in its SIP providing this authority. In addition, on October 3, 2016, EPA proposed to revise provisions in the PSD permitting regulations applicable to GHGs to fully conform with UARG and the Amended Judgment, but those revisions have not been finalized. See 81 FR 68110.
By revising the IBR date of 40 CFR 52.21 to February 17, 2016, Mississippi's June 7, 2016 SIP revision incorporates the GHG Step 3 Rule and removes permitting requirements for Step 2 sources.
B. Grandfather Provisions for 2012 Primary Annual PM2.5 and 2015 Ozone NAAQS
Pursuant to section 165(a)(3)(B) of the CAA and the implementing PSD regulations at 40 CFR 52.21(k)(1) and Start Printed Page 3701751.166(k)(1), EPA requires that PSD permit applications include a demonstration that emissions from the proposed facility will not cause or contribute to a violation of any NAAQS that is in effect on the date the PSD permit is issued. On January 15, 2013 (78 FR 3086), and October 26, 2015 (80 FR 65292), EPA published new primary annual PM2.5 NAAQS and 8-hour ozone NAAQS, respectively. In these two revisions to the NAAQS, EPA established limited grandfathering provisions for certain PSD permit applications pending on the effective date of these revised NAAQS. Additionally, the revisions to both standards included the option to allow states and other air agencies that issue PSD permits under SIP-approved PSD programs to adopt a comparable grandfathering provision, as long as the provision is at least as stringent as that added to 40 CFR 51.166.
For the 2012 primary annual PM2.5 NAAQS, sources with PSD permit applications that meet one of the following conditions would be allowed to give a demonstration that the source requesting the permit does not cause or contribute to a violation of the NAAQS based on the previous 1997 primary annual PM2.5 standard instead of the revised 2012 standard: (1) Applications that have been determined to be complete on or before December 14, 2012; or (2) applications for which public notice of a draft permit or preliminary determination has been published as of the effective date of the revised 2012 PM2.5 NAAQS (March 18, 2013).
For the 2015 8-hour ozone NAAQS revision, sources with PSD permit applications that meet one of the following conditions would be allowed to give a demonstration that the source requesting the permit does not cause or contribute to a violation of the NAAQS based on the previous 2008 8-hour ozone standard, instead of the revised 2015 standard: (1) Applications for which the reviewing authority has formally determined that the application is complete on or before October 1, 2015; or (2) applications for which the reviewing authority has first published a public notice of the draft permit or preliminary determination before the effective date of the revised 2015 8-hour ozone NAAQS (December 28, 2015).
By revising the IBR date of 40 CFR 52.21 to February 17, 2016, Mississippi's June 7, 2016 SIP revision incorporates both the 2012 annual PM2.5 and 2015 8-hour ozone grandfathering provisions for the PSD program.
C. PM2.5 Condensables Correction Rule
On May 16, 2008, EPA finalized a rule titled “Implementation of the New Source Review (NSR) Program for Particulate Matter Less Than 2.5 Micrometers (PM2.5),” Final Rule, 73 FR 28321 (May 16, 2008) (hereinafter referred to as the 2008 NSR PM2.5 Rule). The 2008 NSR PM2.5 Rule revised the Federal NSR program requirements to establish the framework for implementing preconstruction permit review for the PM2.5 NAAQS in both attainment and NAAs. Among other things, the rule revised the definition of “regulated NSR pollutant” for PSD to add a paragraph providing that “particulate matter (PM) emissions, PM2.5 emissions and PM10 emissions shall include gaseous emissions from a source or activity which condense to form particulate matter at ambient temperatures” and that on or after January 1, 2011, “such condensable particulate matter shall be accounted for in applicability determinations and in establishing emissions limitations for PM, PM2.5 and PM10 in permits.” See 73 FR 28321 at 28348. A similar paragraph added to the nonattainment new source review (NNSR) rule does not include “particulate matter (PM) emissions.” See 40 CFR 51.165(a)(1)(xxxvii)(D).
On October 25, 2012, EPA took final action to amend the definition of “regulated NSR pollutant” promulgated in the 2008 NSR PM2.5 Rule regarding the PM condensable provision at 40 CFR 51.166(b)(49)(vi), 52.21(b)(50)(i) and Appendix S to 40 CFR 51. See 77 FR 65107. The PM2.5 Condensables Correction Rule removed the inadvertent requirement in the 2008 NSR PM2.5 Rule that the measurement of condensable particulate matter be included as part of the measurement and regulation of “particulate matter emissions” under the PSD program. The term “particulate matter emissions” includes filterable particles that are larger than PM2.5 or PM10 and is an indicator measured under various New Source Performance Standards (NSPS). See 40 CFR part 60.
By revising the IBR date of 40 CFR 52.21 to February 17, 2016, Mississippi's June 7, 2016 SIP revision captures the PM2.5 Condensables Correction Rule promulgated by EPA on October 25, 2012. See 77 FR 65107.
III. Analysis of State's Submittal
Mississippi currently has a SIP-approved NSR program for PSD at 11-MAC-Part 2-5, including the regulation of GHGs under Step 1 and Step 2 of the GHG Tailoring Rule. The June 7, 2016 submittal revises the PSD regulations by changing the incorporation by reference date of 40 CFR 52.21 and 40 CFR 51.166 at 11-MAC-Part 2-5 Rule 5.1 and Rule 5.2 from November 4, 2011, to February 17, 2016.
The effect of changing this incorporation by reference date at 40 CFR 52.21 is to include four changes to the PSD rules: (1) The adoption of GHG PAL provisions pursuant to the GHG Step 3 Rule; (2) the removal of permitting requirements for Step 2 sources; (3) the incorporation of 2012 PM2.5 and 2015 8-hour ozone NAAQS grandfathering provisions; and (4) the incorporation of the correction to the PM2.5 condensables provision as promulgated in the PM2.5 Condensables Correction Rule.
Mississippi's June 7, 2016 SIP revision seeks to add to the SIP elements of the EPA's July 12, 2012 rule implementing Step 3 of the phase-in of PSD permitting requirements for GHGs described in the GHG Step 3 Rule. Specifically, the incorporation of the GHG Step 3 Rule provisions will allow GHG-emitting sources to obtain PALs for their GHG emissions on a CO2e basis. As explained in Section II.A above, a PAL establishes a site-specific plantwide emission level for a pollutant, which allows the source to make changes to individual units at the facility without triggering the requirements of the PSD program, provided that facility-wide emissions do not exceed the PAL.
The Federal GHG PAL regulations include provisions that apply solely to GHG-only, or Step 2, sources. Some of these provisions may no longer be applicable in light of the Supreme Court's decision in UARG and the D.C. Circuit's Amended Judgment. Since the Supreme Court has determined that sources and modifications may not be defined as “major” solely on the basis of GHGs emitted or increased, PALs for GHGs may no longer have value in some situations where a source might have triggered PSD based on GHG emissions alone. EPA has proposed action in an October 3, 2016 proposed rule to clarify the GHG PAL rules. See 81 FR 68110. However, PALs for GHGs may still have a role to play in determining whether a Start Printed Page 37018source that is already subject to PSD for a pollutant other than GHGs should also be subject to PSD for GHGs.
Moreover, the existing GHG PALs regulations do not add new requirements for sources or modifications that only emit or increase greenhouse gases above the major source threshold or the 75,000 ton per year GHG level in 40 CFR 52.21(b)(49)(iv). Rather, the PALs provisions provide increased flexibility to sources that wish to address their GHG emissions in a PAL. Since this flexibility may still be valuable to sources in at least one context described above, the Agency believes that it is appropriate to approve these provisions into the Mississippi SIP at this time.
Mississippi's June 7, 2016 submittal incorporates the Federal PSD provisions as of February 17, 2016, which is after the UARG decision, the D.C. Circuit's Amended Judgment, and EPA's August 19, 2015 Good Cause GHG Rule. Therefore, Mississippi incorporates fixes to the Federal rules to discontinue regulation of GHG-only, or Step 2, sources with this SIP revision. EPA is approving the removal of the regulation of Step 2 sources with this action.
EPA has concluded that approving these changes into the SIP will not interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in section 171), or any other applicable requirement of the CAA. Step 2 of the GHG Tailoring Rule was invalidated. EPA discussed the effects of PALs in the Supplemental Environmental Analysis of the Impact of the 2002 Final NSR Improvement Rules (November 21, 2002) (Supplemental Analysis). The Supplemental Analysis explained, “[t]he EPA expects that the adoption of PAL provisions will result in a net environmental benefit. Our experience to date is that the emissions caps found in PAL-type permits result in real emissions reductions, as well as other benefits.” Supplemental Analysis at 6; see also 76 FR 49313, 49315 (August 10, 2011). EPA is therefore approving the PALs provisions into the Mississippi SIP, as incorporated by reference.
Mississippi's June 7, 2016 SIP revision also incorporates revisions to the PSD permitting requirements for both the 2012 primary annual PM2.5 (See 78 FR 3086 (January 15, 2013)) and the 2015 ozone 8-hour (See 80 FR 65292 (October 26, 2015)) NAAQS. The new incorporation by reference date adds limited grandfathering provisions for both standards that allows sources who are eligible to meet the previous standard for these NAAQS instead of the newly promulgated standards. EPA is approving these grandfathering provisions of the 2012 primary annual PM2.5 and the 2015 8-hour ozone NAAQS, as incorporated by reference. EPA has concluded that this change will not interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in section 171), or any other applicable requirement of the CAA. The rationale for allowing states to include these grandfathering provisions into their SIPs is discussed in detail at 78 FR 3086 (January 15, 2013) (2012 primary annual PM2.5 NAAQS) and 80 FR 65292 (October 26, 2015) (2015 8-hour ozone NAAQS). EPA is therefore approving these grandfathering provisions into the Mississippi SIP, as incorporated by reference.
Finally, by changing the incorporation by reference date for 11-MAC-Part 2-5 in the SIP revision, Mississippi also adopts changes made by EPA in the PM2.5 Condensables Correction Rule. See 77 FR 65107 (October 25, 2012). As explained in Section II.C, the Federal rule corrected an inadvertent error in the definition of “regulated NSR pollutant” at 40 CFR 52.21(b)(50). EPA has concluded that this change will not interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in section 171), or any other applicable requirement of the CAA, and is approving this revision to the Mississippi SIP.
IV. Incorporation by Reference
In this rule, EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is finalizing the incorporation by reference of Rule 5.1 and Rule 5.2 at Mississippi Administrative Code, Title 11, Part 2, Chapter 5, entitled “Regulations for the Prevention of Significant Deterioration of Air Quality,” effective May 28, 2016, which revises PSD rules.
Therefore, these materials have been approved by EPA for inclusion in the SIP, have been incorporated by reference by EPA into that plan, are fully federally enforceable under sections 110 and 113 of the CAA as of the effective date of the final rulemaking of EPA's approval, and will be incorporated by reference by the Director of the Federal Register in the next update to the SIP compilation.
EPA has made, and will continue to make, these materials generally available through www.regulations.gov and/or at the EPA Region 4 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information).
V. Final Action
EPA is taking a direct final action to approve the portion of Mississippi's June 7, 2016 SIP revision to update the IBR date for the Federal requirements of the PSD program. This SIP revision is intended to make Mississippi's state permitting rule consistent with the Federal requirements, as promulgated by EPA. The June 7, 2016 SIP submission updates the IBR date at 11-MAC-Part 2-5 to February 17, 2016, for the Federal PSD permitting regulations at 40 CFR 52.21 and 51.166. By revising the IBR date, this SIP revision modifies the existing GHG PSD permitting program and incorporates PSD provisions related to the 2012 primary annual PM2.5 and 2015 8-hour ozone NAAQS.
EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comments be filed. This rule will be effective October 10, 2017 without further notice unless the Agency receives adverse comments by September 7, 2017.
If EPA receives such comments, then EPA will publish a document withdrawing the final rule and informing the public that the rule will not take effect. All adverse comments received will then be addressed in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period. Parties interested in commenting should do so at this time. If no such comments are received, the public is advised that this rule will be effective on October 10, 2017 and no further action will be taken on the proposed rule.
VI. 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. See 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 Start Printed Page 37019those imposed by state law. For that reason, this 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 in Executive Order 13132 (64 FR 43255, August 10, 1999);
- is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
- is not a significant regulatory action subject to Executive 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, under Executive Order 12898 (59 FR 7629, February 16, 1994).
The SIP is not approved to apply on any Indian reservation land or in any other area where 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 as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.
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 action 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 CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 10, 2017. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action 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. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today's Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2).
