### 45528 Federal Register / Vol. 77, No. 148 / Wednesday, August 1, 2012 / Proposed Rules

EPA. On March 14, 2012, Delaware submitted a formal revision to the State Implementation Plan (SIP) (the March 2012 SIP submission). The SIP revision consists of amendments to 7 DE Admin. Code 1125, ‘‘Requirements for Preconstruction Review.’’ This SIP revision generally pertains to two Federal rulemaking actions regarding PM 2.5 . The first is the ‘‘Implementation of the New Source Review (NSR) Program for Particulate Matter less than 2.5 Micrometers (PM 2.5 )’’ (NSR PM 2.5 Rule), which was promulgated on May 16, 2008 (73 FR 28321). The second is the ‘‘Prevention of Significant Deterioration (PSD) for Particulate Matter less than 2.5 Micrometers (PM 2.5 )—Increments, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC)’’ (PSD PM 2.5 Rule), which was promulgated on October 20, 2010 (75 FR 64864).

Whenever a new or revised NAAQS is promulgated, section 110(a) of the CAA imposes obligations upon states to submit SIP revisions that provide for the implementation, maintenance, and enforcement of the new or revised NAAQS within three years following the promulgation of such NAAQS—the ‘‘Infrastructure SIP’’ revisions. Although states typically have met many of the basic program elements required in section 110(a)(2) through earlier SIP submissions in connection with previous particulate matter (PM) standards, states (including all the EPA Region III states) were still required to submit SIP revisions that address section 110(a)(2) for the 1997 and 2006 PM 2.5 NAAQS. In addition to the March 2012 SIP submission, Delaware has previously submitted SIP revisions addressing requirements set forth in CAA section 110(a)(2) for the 1997 and 2006 PM 2.5 NAAQS, as well as the 1997 ozone and 2008 lead NAAQS. Because these SIP submissions addressed Delaware’s compliance with CAA section 110(a)(2), these SIP submissions are referred to as Infrastructure SIP submissions. These previous submittals, as well as a technical support document (TSD), are included in the docket for today’s action. The TSD contains a detailed discussion of these submittals and their relationship to the requirements of CAA section 110(a)(2).

A. Fine Particulate Matter and the NAAQS

On July 18, 1997, EPA revised the NAAQS for PM to add new standards for fine particles, using PM2.5 as the indicator. Previously, EPA used PM 10 (inhalable particles smaller than or equal to 10 micrometers in diameter) as the indicator for the PM NAAQS. EPA established health-based (primary) annual and 24-hour standards for PM2.5 , setting an annual standard at a level of 15 micrograms per cubic meter (mg/m 3 ) and a 24-hour standard at a level of 65

mg/m 3 (62 FR 38652). At the time the 1997 primary standards were established, EPA also established welfare-based (secondary) standards identical to the primary standards. The secondary standards are designed to protect against major environmental effects of PM 2.5 , such as visibility impairment, soiling, and materials damage. On October 17, 2006, EPA revised the primary and secondary NAAQS for PM 2.5 . In that rulemaking, EPA reduced the 24-hour NAAQS for PM 2.5 to 35 mg/m 3 and retained the existing annual PM 2.5 NAAQS of 15 mg/

m 3 (71 FR 61236). B. Implementation of NSR Requirements for PM 2.5—the NSR PM 2.5 Rule On May 16, 2008, EPA finalized the NSR PM 2.5 Rule to implement the 1997 PM 2.5 NAAQS, including changes to the NSR program (73 FR 28321). The 2008 NSR PM 2.5 Rule revised the NSR program requirements to establish the framework for implementing preconstruction permit review for the PM 2.5 NAAQS in both attainment and nonattainment areas. The 2008 NSR PM 2.5 Rule also established the following NSR requirements to implement the PM 2.5 NAAQS: (1) Require NSR permits to address directly emitted PM 2.5 and precursor pollutants; (2) establish significant emission rates for direct PM 2.5 and precursor pollutants (including sulfur dioxide (SO 2) and oxides of nitrogen (NO X); (3) establish PM 2.5 emission offsets; and (4) require states to account for gases that condense to form particles (condensables) in PM 2.5 emission limits.

Additionally, the 2008 final rule authorized states to adopt provisions in their nonattainment NSR rules that would allow major stationary sources and major modifications which will be located or take place in areas designated nonattainment for PM 2.5 to offset emissions increases of direct PM 2.5 emissions or PM 2.5 precursors with reductions of either direct PM 2.5 emissions or PM 2.5 precursors in accordance with offset ratios contained in the approved SIP for the applicable nonattainment area. The inclusion, in whole or in part, of the interpollutant offset provisions for PM 2.5 is discretionary on the part of the states. In the preamble to the 2008 final rule, EPA included preferred or presumptive offset ratios, applicable to specific PM 2.5 precursors that states may adopt in conjunction with the new interpollutant offset provisions for PM 2.5 and for which the state could rely on the EPA’s technical work to demonstrate the adequacy of the ratios for use in any PM 2.5 non attainment area. Alternatively, the preamble indicated that states may adopt their own ratios, subject to the EPA’s approval, that would have to be substantiated by modeling or other technical demonstrations of the net air quality benefit for ambient PM 2.5 concentrations.

The preferred ratios were subsequently the subject of a petition for reconsideration which the Administrator granted. EPA continues to support the basic policy that sources may offset increases in emissions of direct PM 2.5 or of any PM 2.5 precursor in a PM 2.5 nonattainment area with actual emissions reductions in direct PM 2.5 or PM 2.5 precursors in accordance with offset ratios as approved in the SIP for the applicable nonattainment area. However, we no longer consider the preferred ratios set forth in the preamble to the 2008 final rule for PM 2.5 NSR implementation to be presumptively approvable. Instead, any ratio involving PM 2.5 precursors adopted by the state for use in the interpollutant offset program for PM 2.5 nonattainment areas must be accompanied by a technical demonstration that shows the net air quality benefits of such ratio for the PM 2.5 nonattainment area in which it will be applied.

C. PSD PM 2.5 Rule

On October 20, 2010 (75 FR 64865), EPA promulgated the final ‘‘Prevention of Significant Deterioration (PSD) for Particulate Matter less than 2.5 Micrometers (PM 2.5 )—Increments, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC)’’ (PSD PM 2.5 Rule). That rulemaking finalized certain program provisions under the regulations to prevent significant deterioration of air quality due to emissions of PM 2.5 (i.e., under the PM 2.5 PSD regulations). This final rule supplemented the final implementation rule for PM 2.5 , known as the Clean Air Fine Particle Implementation Rule (CAFPIR) that we promulgated on April 25, 2007 (72 FR 20586), and the PM 2.5 NSR Implementation Rule that we promulgated on May 16, 2008 (73 FR 28321). Together, these three rules establish a regulatory framework for implementation of a PM 2.5 program in any area. This final rule established increments, SILs, and an SMC for PM 2.5 to facilitate ambient air quality monitoring and modeling under the PSD


### 45529 Federal Register / Vol. 77, No. 148 / Wednesday, August 1, 2012 / Proposed Rules

regulations for areas designated attainment or unclassifiable for PM 2.5 . D. Infrastructure Requirements Relating to Delaware’s PSD Permit Program

With the addition of the PM 2.5 requirements described above, Delaware’s nonattainment NSR and PSD programs contain all of the emission limitations and control measures and other program elements required by 40 CFR 51.165 and 40 CFR 51.166 related to the PM 2.5 NAAQS. Therefore, we also are proposing to approve the March 2012 SIP submittal and the relevant portions of Delaware’s Infrastructure SIP submittals relating to the PSD permit program requirements under CAA sections 110(a)(2)(D)(i)(II) for the 1997 ozone and PM 2.5 NAAQS, the 2006 PM 2.5 NAAQS, and the 2008 lead NAAQS. EPA also is proposing to approve the relevant portion of Delaware’s submittal relating to the PSD permit program pursuant to CAA section 110(a)(2)(C) and (J) for the 2008 lead NAAQS. As already noted, the TSD for this action contains a detailed discussion of the relevant submissions and EPA’s rationale for making this determination. II. Summary of SIP Revision

The March 2012 SIP revision submitted by Delaware consists of amendments to 7 DE Admin. Code 1125, Requirements for Preconstruction Review. The revision fulfills the federal program requirements established by the 2008 NSR PM 2.5 Rule. The amendments establish the major source threshold, significant emission rate and offset ratios for PM 2.5 , establish NO X and SO 2 as precursors to PM 2.5 , and establish the allowance for interpollutant trading for offsets and NSR applicability to PM 2.5 precursor pollutants, pursuant to the May 2008 NSR PM 2.5 Rule. In addition, the amendments add maximum allowable ambient pollutant concentrations (increments) and an SMC for PM 2.5 pursuant to the October 2010 PSD PM 2.5 Rule.

The amendments add definitions, in Section 1 (General Provisions), for the following terms: ‘‘major source baseline date,’’ ‘‘condensable particulate matter,’’ ‘‘direct PM 2.5 ,’’ and ‘‘filterable PM.’’ The amendments revise the definitions of existing terms ‘‘baseline area,’’ ‘‘baseline concentration,’’ ‘‘building, structure, facility or installation,’’ ‘‘minor source baseline date,’’ and ‘‘significant’’ to include the requirements for PM 2.5 to support the amendments to Chapter 1125. Section 2.2.5 is added to Chapter 2.0, Emission Offset Provisions, to identify NO X and SO 2 as precursors. Section 2.4.3.3 is added to allow emissions offsets of SO 2 , NO X or PM 2.5 at a 1-to-1 ratio for the same criteria pollutants. Section 2.5.7 is added to Chapter 2.0 to allow interpollutant trading between direct PM2.5 emissions and SO 2 or NO X emissions using a ratio that would be approved by Delaware after public review and comment and then approved by EPA as a SIP revision. Section 3.2 in Chapter 3.0, Prevention of Significant Deterioration of Air Quality, is modified to establish increments for PM 2.5 . Section 3.7 (Review of Major Stationary Sources and Major Modifications—Source Applicability and Exemptions) is revised at Section 3.7.7.1 to establish an SMC for PM 2.5 . No other changes to increments or SMCs for other regulated NSR pollutants are being addressed in this SIP approval.

The amendments submitted in March 2012 by Delaware for approval into the SIP were adopted by Delaware on January 17, 2012 and became effective on February 11, 2012. Based upon EPA’s review of the revisions submitted by Delaware for approval into the SIP, EPA finds these revisions to be consistent with their Federal counterparts.

The revisions submitted by the State of Delaware to address the new PSD requirements for PM 2.5 pursuant to the EPA’s October 20, 2010 final rule include the regulatory text at 40 CFR 51.166(k)(2), concerning the implementation of SILs for PM 2.5 . (See, 7 DE Admin. Code 1125 Section 3.9 (Source Impact Analysis)). We stated in the preamble to the 2010 final rule that we do not consider the SILs to be a mandatory SIP element, but regard them as discretionary on the part of permitting authority for use in the PSD permitting process. Nevertheless, the PM 2.5 SILs are currently the subject of litigation before the U.S. Court of Appeals (D.C. Circuit). In response to that litigation, the EPA has requested that the Court remand and vacate the regulatory text in the EPA’s PSD regulations at paragraph (k)(2) of section 51.166 so that the EPA can make necessary rulemaking revisions to that

text.

In light of EPA’s request for remand and vacatur and our acknowledgement of the need to revise the regulatory text presently contained at paragraph (k)(2) of sections 51.166 and 52.21, we do not believe that it is appropriate at this time to approve that portion of the State’s SIP revision that contains the affected regulatory text in the State’s PSD regulations, specifically new section 3.9 of 7 DE Admin. Code 1125. Instead, we are taking no action at this time with regard to that specific provision contained in the SIP revision. III. Proposed Action
Based upon EPA’s review of the March 14, 2012 submittal, EPA finds the revised regulations consistent with their Federal counterparts. Only the increment portion of the October 20, 2010 PM 2.5 rule is a required PSD program element. Therefore, EPA is proposing to approve the Delaware SIP revision with the exception of the SILs as noted earlier, upon which we are taking no action. Additionally, in light of this SIP revision, EPA is proposing to approve the portions of Delaware’s December 13, 2007, March 12, 2008, September 19, 2008, September 16, 2009, and April 1, 2010 infrastructure SIP submittals which address the obligations set forth at CAA section 110(a)(2)(D)(i)(II) relating to Delaware’s PSD permit program for the 1997 PM2.5 and ozone NAAQS as well as for the 2006 PM 2.5 NAAQS. Finally, in light of Delaware’s submission dated October 17, 2011 and the March 2012 SIP revision which address the obligations set forth at CAA sections 110(a)(2)(C), (D)(i)(II) and (J) relating to the Delaware’s PSD permit program, EPA is proposing to determine that Delaware’s SIP meets the statutory obligations relating to its PSD permit program set forth at CAA sections 110(a)(2)(C), (D)(i)(II), and (J) for the 2008 lead NAAQS. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action. IV. 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 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 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


### 45530 Federal Register / Vol. 77, No. 148 / Wednesday, August 1, 2012 / Proposed Rules

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).

In addition, this proposed rule pertaining to NSR requirements for PM 2.5 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.
