applying only to those regulatory actions that concern health or safety risks, such that the analysis required under section 5–501 of the Executive Order has the potential to influence the regulation. This rule is not subject to Executive Order 13045, because it proposes to approve a State rule implementing a Federal standard.

H. Executive Order 13211, Actions That Significantly Affect Energy Supply, Distribution, or Use

This rule is not subject to Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866.
I. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104– 113, 12 (10) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards (VCS) in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. VCS are technical standards ( e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by the VCS bodies. The NTTAA directs EPA to provide Congress, through annual reports to OMB, with explanations when the Agency decides not to use available and applicable VCS. EPA believes that VCS are inapplicable to this action. Today’s action does not require the public to perform activities conducive to the use of VCS.

J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Population

Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States.

EPA has determined that this proposed rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it does not change the level of environmental protection for any affected populations.

I. What is being addressed in this document?

EPA is proposing to approve the SIP revision submitted by the state of Missouri for 10 CSR 10–6.060, ‘‘Construction Permits Required’’. On October 3, 2013, EPA received a request to amend the SIP to incorporate by reference all sections of title 40 part 52.21 of the Code of Federal Regulations (CFR) except for subsections (a), (q) and (s) through July 1, 2012. Missouri is also requesting to amend the SIP to incorporate by reference EPA’s July 12, 2012, final rule finalizing PALs for GHGs (77 FR 41051) and EPA’s October 25, 2012, final rule amending the definition of ‘‘Regulated NSR Pollutant’’ concerning condensable particulate matter (77 FR 65107). In Missouri’s letter to EPA, Missouri also requested to amend the SIP to incorporate EPA’s May 18, 2011, rule repealing the grandfathering provisions for particulate matter less than 2.5 micrometers (PM 2.5 ) under the PSD program, but because the state has an already approved PSD program which incorporates by reference the provisions of 40 CFR 52.21 through July 1, 2011, Missouri’s Federally approved program already incorporates this action. Other revisions to Missouri’s rule which we are proposing to take action on include clarifying the requirements for conducting an air quality analysis in section 5, De Minimis Permits and making minor administrative clarifications as well as revising the notification period for initial start-up in section 6, General Permits.
II. Background

Missouri implements its PSD program by incorporating by reference section 52.21 of the CFR in its rule 10 CSR 10– 6.060, ‘‘Construction Permits Required’’. In a previous action on June 21, 2013, EPA approved the most recent amendment to Missouri’s PSD program (78 FR 37457). Missouri’s currently approved PSD program incorporates by reference (IBR) the Federal regulations as promulgated July 1, 2011, in the CFR, and incorporates the July 20, 2011, rule ‘‘Deferral for CO2 Emissions from Bioenergy and Other Biogenic Sources under the Prevention of Significant Deterioration and Title V Programs’’ (‘‘Biomass Deferral’’ 76 FR 43490). Missouri’s currently approved PSD program contains a number of important required elements, including those related to the 2008 ‘‘Implementation of New Source Review (NSR) Program for Particulate Matter Less Than 2.5 Micrometers (PM2.5 )’’ (2008 NSR PM 2.5 Rule; 73 FR 28321). For PSD sources in Missouri, PSD permits must address direct PM 2.5 emissions as well as precursor emissions (including sulfur dioxide (SO 2) and oxides of nitrogen (NO X)), establish significant emission rates for PM 2.5 and precursor emissions, and establish the requirement to account for condensable particulate matter. On January 4, 2013, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit), in Natural Resources Defense Council v. EPA, issued a decision that remanded the EPA’s rules implementing the 1997
PM 2.5 NAAQS. 1 The court’s remand of the 2008 NSR PM 2.5 Rule is relevant to this final rulemaking. This rule promulgated NSR requirements for implementation of PM 2.5 in both nonattainment areas (nonattainment NSR) and attainment/unclassifiable areas (PSD). The D.C. Circuit found that EPA erred in implementing the PM 2.5 NAAQS pursuant to the general implementation provisions of subpart 1 of part D of title 1 of the CAA, rather than pursuant to the additional implementation provisions specific to particulate matter nonattainment areas in subpart 4. The Court ordered EPA to ‘‘repromulgate these rules pursuant to Subpart 4 consistent with this opinion.’’ (Id. at 437). However, as the requirements of subpart 4 only pertain to nonattainment areas, it is EPA’s position that the portions of the 2008
NSR PM2.5 Rule that address requirements for PM 2.5 in attainment and unclassifiable areas are not affected by the D.C. Circuit’s opinion in NRDC

v. EPA. Moreover, EPA does not anticipate the need to revise any PSD requirements promulgated in the 2008
NSR PM2.5 Rule in order to comply with the court’s decision. Accordingly, EPA’s approval of Missouri’s SIP as to the PSD requirements promulgated by the 2008
NSR PM2.5 Rule does not conflict with the D.C. Circuit’s opinion.

On October 20, 2010, EPA promulgated additional PSD regulations relating to PM2.5 : ‘‘Prevention of Significant Deterioration (PSD) for Particulate Matter Less than 2.5 Micrometers (PM 2.5 )—Increments, Significant Impact Levels (SILs), and Significant Monitoring Concentrations (SMC)’’ (2010 PSD PM 2.5 Rule, 73 FR 64864). On January 22, 2013, the D.C. Circuit, in Sierra Club v. EPA, issued a judgment that, inter alia, vacated and remanded the SIL provisions at section 52.21(k)(2). Additionally, the D.C. Circuit vacated the SMC provisions at section 52.21(i)(5)(i)(c). 2 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, and to revise the SMC for PM 2.5 to zero (78 FR 73698). On March 19, 2013, and October 21, 2013, Missouri submitted additional information to amend their September 5, 2012, SIP submission to clarify that they no longer intended to include the
PM 2.5 SILs and SMC provisions (see 78 FR 37457, June 21, 2013, for more information). Specifically, Missouri Department of Natural Resources (MDNR) will not apply either the PM 2.5 SILs provisions at 40 CFR 51.166(k)(2) and 52.21(k)(2), or the PM 2.5 SMC provisions at 40 CFR 51.166(i)(5)(i)(c) to pending or future PSD permit actions. It is the state’s intent that PM 2.5 will remain on the list of pollutants but that the associated concentration level would be blank or zero. In other words, pre-construction monitoring will continue to apply but without de minimis thresholds. Therefore, the provisions with which the court took issue are not in effect in Missouri.

On June 23, 2014, the United States Supreme Court, in Utility Air Regulatory Group v. Environmental Protection Agency, issued a decision addressing the application of PSD permitting requirements to greenhouse gas (GHG)
emissions. 3 The Supreme Court said that the EPA may not treat GHGs as an air pollutant for purposes of determining whether a source is a major source (or modification thereof) required to obtain a PSD permit. The Court also said that EPA could continue to require that PSD permits, otherwise required based on emissions of pollutants other than GHGs, contain limitations on GHG emissions based on the application of Best Available Control Technology (BACT). In order to act consistently with its understanding of the Court’s decision pending further judicial action before the D.C. Circuit to effectuate the decision, the EPA is not continuing to apply EPA regulations that would require that SIPs include permitting requirements that the Supreme Court found impermissible. Specifically, EPA is not applying the requirement that a state’s SIP-approved PSD program require that sources obtain PSD permits when GHGs are the only pollutant, (i) that the source emits or has the potential to emit above the major source thesholds, or (ii) for which there is a significant emissions increase and a significant net emissions increase from


### 14064 Federal Register / Vol. 80, No. 52 / Wednesday, March 18, 2015 / Proposed Rules

a modification ( e.g. 40 CFR 51.166(b)(48)(v)).

EPA anticipates a need to revise Federal PSD rules in light of the Supreme Court opinion. In addition, EPA anticipates that many states will revise their existing SIP-approved PSD programs in light of the Supreme Court’s decision. This can be accomplished as soon as EPA revises the Federal PSD rules in states that allow future revisions to the Federal PSD program to be automatically incorporated into the SIP. The timing and content of subsequent EPA actions with respect to the EPA regulations is expected to be informed by additional legal processes before the D.C. Circuit. EPA is not expecting states to have revised their existing PSD program regulations at this juncture, before the D.C. Circuit has addressed these issues and before EPA has revised its regulations at 40 CFR 51.166. However, EPA is evaluating PSD program submissions to assure that the state’s program correctly addresses GHGs consistent with the Supreme Court’s decision.

Missouri’s existing approved SIP contains the GHG permitting requirements reflected in 40 CFR 52.21 after EPA issued the Tailoring Rule. As a result, the PSD permitting program in Missouri previously approved by EPA into the SIP continues to require that PSD permits (otherwise required based on emissions of pollutants other than GHGs) contain limitations on GHG emissions based on the application of BACT when sources emit or increase greenhouse gases in the amount of 75,000 tons per year (measured as carbon dioxide equivalent). Although the approved Missouri PSD permitting program may also currently contain provisions that are no longer necessary in light of the Supreme Court decision, this does not prevent EPA from approving the submission addressed in this rule. Missouri’s 2013 SIP submission does not add any GHG permitting requirements that are inconsistent with the Supreme Court decision. While this submission incorporates all of section 52.21 for completeness, except for subsections (a), (q) and (s), the submission mostly reincorporates PSD permitting requirements for GHG’s that are already in the Missouri SIP.

This proposed revision does add to the Missouri SIP the elements of EPA’s July 12, 2012, rulemaking, Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule Step 3 and GHG Plantwide Applicability Limits, ‘‘Step 3 Tailoring Rule’’ (77 FR 41051), which implements Step 3 of the phase in of PSD permitting requirements for GHGs. This rule became effective on August 13, 2012. Specifically, the incorporation of theStep 3 rule provisions will allow GHGemitting sources to obtain plantwide applicability limits (PALs) for their GHG-emitting sources on a carbon dioxide equivalent (CO2e) basis. The GHG PAL provisions, as currently written, include some provisions that may no longer be appropriate in light of the Supreme Court decision. Since the Supreme Court has determined that sources and modifications may not be defined as ‘‘major’’ solely on the basis of the level 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. However, PALs for GHGs may still have a role to play in determining whether a modification that triggers PSD for a pollutant other than GHGs should also be subject to BACT for GHGs. These provisions, like the other GHG provisions discussed previously, will likely be revised pending further legal action. However, these provisions do not add new requirements for sources or modifications that only emit or increase GHGs above the major source threshold or the 75,000 tpy GHG level in section 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, we believe that it is appropriate to approve these provisions into the Missouri SIP at this juncture.

EPA is proposing to revise Missouri’s SIP to incorporate by reference EPA’s October 25, 2012 rule, ‘‘Implementation of the New Source Review Program for Condensable Particulate Matter’’. This revision is appropriate and necessary to ensure that the inadvertent error which was contained in EPA’s 2008 rule, which was previously SIP approved in the Missouri rule (78 FR 37457) is corrected. EPA’s 2008 rule, ‘‘Implementation of the New Source Review (NSR) Program for Particulate Matter Less Than 2.5 Micrometers (PM 2.5 ).’’ See 73 FR 28321 (May 16, 2008), inadvertently included a requirement to consider condensable PM when measuring one of the emissions-related indicators for PM known as ‘‘particulate matter emissions’’ in the context of the PSD and NSR regulations. EPA’s 2012 rule corrects the error in the 2008 rule and therefore it is appropriate and necessary to incorporate by reference the 2012 rule and related corrections to the definition of ‘‘particulate matter emissions.’’
III. Have the requirements for approval of a SIP revision been met?

As stated above, Missouri’s incorporation by reference of all sections of title 40 section 52.21 of the CFR except for subsections (a), (q) and (s) and EPA’s July 12, 2012, final rule on PALs for GHGs (77 FR 41051) and EPA’s October 25, 2012, final rule amending the definition of ‘‘Regulated NSR Pollutant’’ concerning condensable particulate matter (77 FR 65107) are appropriate even in light of recent court actions and ensure that the state PSD program is in agreement with Federal requirements. Missouri also requested to amend the SIP to incorporate EPA’s May 18, 2011, rule repealing the grandfathering provisions for PM2.5 under the PSD program, but because the state has an already approved PSD program which incorporates by reference the provisions of 40 CFR 52.21 through July 1, 2011, Missouri’s Federally approved program already incorporates this action.

Additional revisions include, in paragraph (5)(D)(1) of the rule, Missouri is adding subparagraphs A. and B. which provide clear and specific requirements for when an air quality analysis is required for De Minimis permits. In (5)(D)(2) of the rule, Missouri is adding subparagraphs A., B., and C. which provide clear and specific requirements for when the director may require an air quality analysis. These revisions strengthen Missouri’s PSD

program.

MDNR is making minor administrative edits to subsections (6)(A) and (6)(A)(2). In (6)(E)(1)(A) Missouri is modifying the notification period for initial equipment start-up. This revision shortens the timeframe for which notification is provided to the state prior to initial start-up.

The state submission has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The submission also satisfies the completeness criteria of 40 CFR part 51, appendix V. In addition, as explained above, the revision meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations. MDNR received five (5) comments from one source: The U.S. Environmental Protection Agency. Missouri responded to each of the comments and made revisions to the rule as appropriate. Overall, these actions strengthen the Missouri SIP, by ensuring the state PSD program incorporates recent Federal PSD updates. These revisions do not


### 14065 Federal Register / Vol. 80, No. 52 / Wednesday, March 18, 2015 / Proposed Rules

negatively impact air quality, nor relax the SIP.

IV. What action is EPA taking?

EPA is proposing to approve the revisions to the SIP. These revisions update the construction permits rule to incorporate by reference recent EPA actions related to PALs for GHGs, and amend the definition of ‘‘Regulated NSR Pollutant.’’ Other revisions include modifying the notification period for initial equipment start-up and clarifying de minimis permit air quality analysis requirements.

We are processing this rule as a proposed action because we are soliciting comments on this proposed action. Final rulemaking will occur after consideration of any comments.
Statutory and Executive Order Reviews

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, EPA is proposing to incorporate by reference
Missouri 10 CSR 10–6.060 ‘‘Construction Permits Required’’ described in the proposed amendments to 40 CFR part 52 set forth below. EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the appropriate EPA office (see the **ADDRESSES** section of this preamble for more information).

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, 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 action:

• Is not a ‘‘significant regulatory action’’ under the terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is therefore not subject to review under Executive Orders 12866 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 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).

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 May 18, 2015. Filing a petition for reconsideration by the Administrator of this proposed rule does not affect the finality of this rulemaking 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 effectivess of such future rule or action. This proposed action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
