### 76251 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

Federalism, if it has a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. We have analyzed this proposed rule under that
Order and have determined that it does not have implications for federalism.

6. Protest Activities

The Coast Guard respects the First Amendment rights of protesters.
Protesters are asked to contact the person listed in the **FOR FURTHER**

**INFORMATION CONTACT** section to coordinate protest activities so that your message can be received without jeopardizing the safety or security of people, places or vessels.

7. Unfunded Mandates Reform Act

The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531–1538) requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 (adjusted for inflation) or more in any one year. Though this proposed rule will not result in such an expenditure, we do discuss the effects of this proposed rule elsewhere in this preamble.

8. Taking of Private Property

This proposed rule would not cause a taking of private property or otherwise have taking implications under Executive Order 12630, Governmental
Actions and Interference with Constitutionally Protected Property Rights.

9. Civil Justice Reform

This proposed rule meets applicable standards in sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, eliminate ambiguity, and reduce
burden.

10. Protection of Children

We have analyzed this proposed rule under Executive Order 13045,
Protection of Children from Environmental Health Risks and Safety Risks. This rule is not an economically significant rule and would not create an
environmental risk to health or risk to safety that might disproportionately
affect children.

11. Indian Tribal Governments

This proposed rule does not have tribal implications under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, because it would not have
a substantial direct effect on one or more Indian tribes, on the relationship
between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the
Federal Government and Indian tribes.

12. Energy Effects

This proposed rule is not a ‘‘significant energy action’’ under Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use.

13. Technical Standards

This proposed rule does not use technical standards. Therefore, we did not consider the use of voluntary
consensus standards.

14. Environment

We have analyzed this proposed rule under Department of Homeland Security Management Directive 023–01
and Commandant Instruction M16475.lD, which guides the Coast Guard in complying with the National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321–4370f), and have made a preliminary determination that this action is one of a category of actions which do not individually or cumulatively have a significant effect on the human environment. This proposed rule simply promulgates the operating regulations or procedures for drawbridges. This rule is categorically excluded, under figure 2–1, paragraph (32)(e), of the Instruction.

Under figure 2–1, paragraph (32)(e), of the Instruction, an environmental analysis checklist and a categorical
exclusion determination are not required for this rule. We seek any comments or information that may lead to the discovery of a significant environmental impact from this proposed rule.

List of Subjects in 33 CFR Part 117

**SUMMARY :**  The Environmental Protection Agency (EPA) is proposing to approve the Commonwealth of Pennsylvania (Commonwealth or Pennsylvania) request to redesignate to attainment the Reading, Pennsylvania nonattainment area (Reading Area or the Area) for the 1997 annual fine particulate matter (PM 2.5 ) national ambient air quality standard (NAAQS). In addition, EPA is proposing to approve, as a revision to the Pennsylvania State Implementation Plan (SIP), the Reading Area maintenance plan to show maintenance
of the 1997 annual PM 2.5 NAAQS through 2025 for the Area. The maintenance plan includes the 2017 and

2025 PM 2.5 and nitrogen oxides (NO X ) mobile vehicle emissions budgets (MVEBs) for the Reading Area for the
1997 annual PM 2.5 NAAQS, which EPA is proposing to approve for transportation conformity purposes. EPA is also proposing to find adequate the MVEBs for Berks County. Finally, EPA is proposing to approve, as a revision to the Pennsylvania SIP, the 2007 base year emissions inventory for
the Area for the 1997 annual PM 2.5 NAAQS.

I. Background

The first air quality standards for

PM 2.5 were established on July 18, 1997 (62 FR 38652). EPA promulgated an
annual standard at a level of 15 micrograms per cubic meter ( mg/m 3 ), based on a three-year average of annual

mean PM 2.5 concentrations (the 1997
annual PM 2.5 standard or the standard). In the same rulemaking, EPA promulgated a 24-hour standard of 65

mg/m 3 based on a three-year average of the 98th percentile of 24-hour

concentrations.

On January 5, 2005 (70 FR 944, 1014), EPA published air quality area designations for the 1997 PM 2.5 NAAQS. In that rulemaking action, EPA designated the Reading Area as
nonattainment for the 1997 annual

PM 2.5 NAAQS. The Reading Area is comprised of Berks County in Pennsylvania. See 40 CFR 81.339 (Pennsylvania). Since the Reading Area is designated nonattainment for the annual NAAQS promulgated in 1997, today’s proposed rulemaking action addresses the redesignation to attainment only for this standard.

On September 25, 2009 (74 FR 48863), EPA determined that the Reading Area
had attained the 1997 annual PM 2.5 NAAQS. Pursuant to 40 CFR 51.1004(c) and based on this determination, the requirements for the Reading Area to
submit an attainment demonstration and associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, and other planning SIP
revisions related to the attainment of the
1997 annual PM 2.5 NAAQS are suspended until such time as: the Area is redesignated to attainment for the standard, at which time the section 51.1004(c) requirements no longer apply, or EPA determines that the Area has again violated the standard, at which time such plans are required to be submitted. On July 29, 2011 (76 FR 45424), EPA determined that the Reading Area had attained the 1997
annual PM 2.5 NAAQS by the statutory attainment date of April 5, 2010. EPA’s
review of the most recent certified monitoring data for the Area shows that
the Area continues to attain the
standard.

On November 25, 2013, the Commonwealth of Pennsylvania, through the Pennsylvania Department of Environmental Protection (PADEP), formally submitted a request to redesignate the Reading Area from
nonattainment to attainment for the
1997 annual PM 2.5 NAAQS. Concurrently, PADEP submitted a maintenance plan for the Area as a SIP
revision to ensure continued attainment throughout the Area over the next 10 years. The maintenance plan includes
the 2017 and 2025 PM 2.5 and NO X MVEBs for the Areas for the 1997
annual PM 2.5 NAAQS, which EPA is proposing to approve for transportation conformity purposes. PADEP also submitted a 2007 comprehensive emissions inventory for the 1997 annual

PM 2.5 NAAQS for PM 2.5 , NO X , sulfur dioxide (SO 2 ), volatile organic compounds (VOC), and (ammonia) NH 3

. EPA is proposing to approve as a SIP revision the maintenance plan for the
1997 annual PM 2.5 NAAQS. EPA is also proposing to approve the 2007 emissions inventory to meet the emissions inventory requirement of section 172(c)(3) of the CAA.

II. EPA’s Requirements

A. Criteria for Redesignation to

Attainment

The CAA provides the requirements for redesignating a nonattainment area


### 76253 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

1 CAIR addressed the 1997 PM 2.5 annual NAAQS and the 1997 8-hour ozone NAAQS. CSAPR addresses contributions from upwind states to
downwind nonattainment and maintenance of the
2006 24-hour PM 2.5 NAAQS as well as the ozone
and PM 2.5 NAAQS addressed by CAIR. to attainment. Specifically, section 107(d)(3)(E) of the CAA allows for redesignation providing that: (1) EPA
determines that the area has attained the applicable NAAQS; (2) EPA has fully approved the applicable implementation plan for the area under section 110(k) of the CAA; (3) EPA determines that the improvement in air quality is due to permanent and
enforceable reductions in emissions resulting from implementation of the applicable SIP and applicable Federal air pollutant control regulations and other permanent and enforceable reductions; (4) EPA has fully approved a maintenance plan for the area as meeting the requirements of section 175A of the CAA; and, (5) the state containing such area has met all requirements applicable to the area under section 110 and part D of the CAA. Each of these requirements are discussed in section V (EPA’s Analysis of Pennsylvania’s SIP Submittal) of today’s proposed rulemaking action.

EPA provided guidance on redesignation in the ‘‘SIPs; General Preamble for the Implementation of
Title I of the CAA Amendments of 1990,’’ (57 FR 13498, April 16, 1992) (the ‘‘General Preamble’’) and has provided further guidance on processing redesignation requests in the following documents: (1) ‘‘Procedures for Processing Requests to Redesignate Areas to Attainment,’’ Memorandum from John Calcagni, Director, Air Quality Management Division, September 4, 1992 (hereafter referred to as the ‘‘1992 Calcagni Memorandum’’); (2) ‘‘SIP Actions Submitted in Response to CAA Deadlines,’’ Memorandum from John Calcagni, Director, Air Quality Management Division, October 28, 1992; and (3) ‘‘Part D New Source Review (Part D NSR) Requirements for Areas Requesting Redesignation to Attainment,’’ Memorandum from Mary D. Nichols, Assistant Administrator for Air and Radiation, October 14, 1994.

B. Requirements of a Maintenance Plan

Section 175A of the CAA sets forth the elements of a maintenance plan for areas seeking redesignation from
nonattainment to attainment. Under section 175A of the CAA, the plan must
demonstrate continued attainment of the applicable NAAQS for at least 10 years after approval of a redesignation of an area to attainment. Eight years after the redesignation, the state must submit a revised maintenance plan demonstrating that attainment will
continue to be maintained for the 10 years following the initial 10-year period. To address the possibility of future NAAQS violations, the maintenance plan must contain such contingency measures, with a schedule for implementation, as EPA deems necessary to assure prompt correction of any future PM 2.5 violations.

The 1992 Calcagni Memorandum provides additional guidance on the content of a maintenance plan. The
memorandum states that a maintenance plan should address the following provisions: (1) An attainment emissions inventory; (2) a maintenance demonstration showing maintenance for 10 years; (3) a commitment to maintain the existing monitoring network; (4) verification of continued attainment; and (5) a contingency plan to prevent or correct future violations of the NAAQS.

Under the CAA, states are required to submit, at various times, control strategy SIP revisions and maintenance plans for
nonattainment areas and for areas seeking redesignation to attainment for a given NAAQS. These emission control strategy SIP revisions ( e.g., RFP and attainment demonstration SIP revisions) and maintenance plans create MVEBs
based on onroad mobile source
emissions for the relevant criteria pollutants and/or their precursors, where appropriate, to address pollution from onroad transportation sources. The MVEBs are the portions of the total
allowable emissions that are allocated to onroad vehicle use that, together with
emissions from all other sources in the area, will provide attainment, RFP, or maintenance, as applicable. The budget serves as a ceiling on emissions from an area’s planned transportation system. Under 40 CFR part 93, a MVEB for an area seeking a redesignation to
attainment is established for the last year of the maintenance plan.

The maintenance plan for the Reading
Area includes the 2017 and 2025 PM 2.5 and NO X MVEBs for transportation conformity purposes. The transportation conformity determination for the Area is
further discussed in subsection C of section V (Transportation Conformity) of today’s proposed rulemaking action and in a technical support document (TSD) dated April 29, 2014, which is available in the docket for this proposed rulemaking action.

III. Summary of Proposed Actions

EPA is proposing to take several rulemaking actions related to the redesignation of the Reading Area to
attainment for the 1997 annual PM 2.5 NAAQS. EPA is proposing to find that the Area meets the requirements for redesignation for the 1997 annual PM 2.5 NAAQS under section 107(d)(3)(E) of the CAA. EPA is also proposing to approve the associated maintenance plan for the Reading Area as a revision to the Pennsylvania SIP for the 1997
annual PM 2.5 NAAQS, including the
2017 and 2025 PM 2.5 and NO X MVEBs for the Area. The approval of the maintenance plan is one of the CAA criteria for redesignation of the Area to
attainment for the 1997 annual PM 2.5 NAAQS. Pennsylvania’s maintenance plan is designed to ensure continued attainment in the Reading Area for 10 years after redesignation.

EPA previously determined that the Reading Area has attained the 1997
annual PM 2.5 NAAQS. See 76 FR 45424, (July 27, 2011). In this rulemaking action, EPA proposes to find that the
Area continues to attain the standard. EPA is also proposing to approve the 2007 comprehensive emissions inventory that includes PM 2.5, SO 2 , NO X , VOC, and NH 3 for the Reading Area as a revision to the Pennsylvania
SIP for the 1997 annual PM 2.5 NAAQS in order to meet the requirements of section 172(c)(3) of the CAA.

IV. Effects of Recent Court Decisions on Proposed Actions

A. Effects of EME Homer City Decision

1. Background

The U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit Court) and the Supreme Court
have issued a number of decisions and orders regarding the status of EPA’s regional trading programs for transported air pollution, the Clean Air Interstate Rule (CAIR) and the Cross State Air Pollution Rule (CSAPR), that impact this proposed redesignation action. In 2008, the D.C. Circuit Court initially vacated CAIR, North Carolina

v. EPA, 531 F.3d 896 (D.C. Cir. 2008), but ultimately remanded the rule to EPA without vacatur to preserve the environmental benefits provided by CAIR, North Carolina v. EPA, 550 F.3d 1176, 1178 (D.C. Cir. 2008). On August 8, 2011 (76 FR 48208), acting on the D.C. Circuit Court’s remand, EPA promulgated CSAPR, to address interstate transport of emissions and resulting secondary air pollutants and to replace CAIR. 1 CSAPR requires
substantial reductions of SO 2 and NO X emissions from electric generating units (EGUs) in 28 states in the Eastern United States. Implementation of CSAPR was scheduled to begin onJanuary 1, 2012, when CSAPR’s capand-trade programs would have superseded the CAIR cap-and-trade

v. EPA, No. 11–1302 (D.C. Cir. Dec. 30, 2011), Order at 2.

On August 21, 2012, the D.C. Circuit Court issued its ruling, vacating and remanding CSAPR to EPA and once again ordering continued implementation of CAIR. EME Homer City Generation, L.P. v. EPA, 696 F.3d 7, 38 (D.C. Cir. 2012). The D.C. Circuit Court subsequently denied EPA’s petition for rehearing en banc. EME Homer City Generation, L.P. v. EPA, No. 11–1302, 2013 WL 656247 (D.C. Cir. Jan. 24, 2013), at *1. EPA and other parties then petitioned the Supreme Court for a writ of certiorari, and the Supreme Court granted the petitions on June 24,

2013. EPA v. EME Homer City Generation, L.P., 133 S. Ct. 2857 (2013).

On April 29, 2014, the Supreme Court
vacated and reversed the D.C. Circuit Court’s decision regarding CSAPR, and
remanded that decision to the D.C. Circuit Court to resolve remaining issues in accordance with its ruling.

EPA v. EME Homer City Generation, L.P., 134 S. Ct. 1584 (2014). EPA moved to have the stay of CSAPR lifted by the D.C. Circuit Court in light of the Supreme Court decision. EME Homer City Generation, L.P. v. EPA, Case No. 11–1302, Document No. 1499505 (D.C. Cir. filed June 26, 2014). In its motion,
EPA asked the D.C. Circuit Court to toll CSAPR’s compliance deadlines by three years, so that the Phase 1 emissions budgets apply in 2015 and 2016 (instead of 2012 and 2013), and the Phase 2 emissions budgets apply in 2017 and beyond (instead of 2014 and beyond). On October 23, 2014, the D.C. Circuit Court granted EPA’s motion and lifted the stay of CSAPR which was imposed on December 30, 2011. EME Homer City Generation, L.P. v. EPA, No. 11–1302 (D.C. Cir. Oct. 23, 2014), Order at 3.

2. Proposal on This Issue

Because CAIR was promulgated in
2005 and incentivized sources and states to begin achieving early emission reductions, the air quality data examined by EPA in issuing a final
determination of attainment for the Reading Area in 2009 (September 25, 2009, 74 FR 48863) and the air quality
data from the Area since 2005 necessarily reflect reductions in emissions from upwind sources as a result of CAIR, and Pennsylvania
includes CAIR as one of the measures that helped to bring the Area into attainment. However, modeling conducted by EPA during the CSAPR rulemaking process, which used a
baseline emissions scenario that ‘‘backed out’’ the effects of CAIR, see 76 FR at 48223, projected that Berks County would have a PM 2.5 annual design value 2 below the level of the
1997 annual PM 2.5 standard for 2012 and 2014 without taking into account
emission reductions from CAIR or

CSAPR. See Appendix B of EPA’s ‘‘Air Quality Modeling Final Rule Technical Support Document,’’ (Page B–57), which
is available in the docket for this proposed rulemaking action. Inaddition, the 2010–2012 qualityassured, quality-controlled, and certified monitoring data for the Reading Area confirms that the PM 2.5 annual design value for the Area
remained well below the 1997 annual

PM 2.5 NAAQS in 2012.

The status of CSAPR is not relevant to this redesignation. CSAPR was promulgated in June 2011, and the rule was stayed by the D.C. Circuit Court just six months later, before the trading programs it created were scheduled to go into effect. Therefore, the Reading
Area’s attainment of the 1997 annual

PM 2.5 standard cannot have been a result of any emission reductions associated with CSAPR. In addition, on October 23, 2014, the D.C. Circuit Court lifted the stay on CSAPR. In sum,
neither the status of CAIR nor the current status of CSAPR affects any of the criteria for proposed approval of this redesignation request for the Area.

B. Effect of the January 4, 2013 D.C. Circuit Court Decision Regarding PM 2.5 Implementation Under Subpart 4 of Part D of Title I of the CAA

1. Background

On January 4, 2013, in NRDC v. EPA,
the D.C. Circuit Court remanded to EPA
the ‘‘Final Clean Air Fine Particle Implementation Rule’’ (72 FR 20586, April 25, 2007) and the ‘‘Implementation of the NSR Program
for PM 2.5 ’’ final rule (73 FR 28321, May 16, 2008) (collectively, ‘‘1997 PM 2.5 Implementation Rule’’). 706 F.3d 428 (D.C. Cir. 2013). The D.C. Circuit Court found that EPA erred in implementing
the 1997 annual PM 2.5 NAAQS pursuant to the general implementation provisions of subpart 1 of Part D of Title I of the CAA (subpart 1), rather than the particulate-matter-specific provisions of subpart 4 of Part D of Title I (subpart 4). Prior to the January 4, 2013 decision, the states had worked towards meeting the air quality goals of the 1997 annual

PM 2.5 NAAQS in accordance with EPA regulations and guidance derived from subpart 1. Subsequent to this decision, EPA took this history into account and responded to the D.C. Circuit Court’s remand by proposing to set a new deadline for any remaining submissions that may be required for a moderate
nonattainment area due to the applicability of subpart 4.

On June 2, 2014 (79 FR 31566) EPA
finalized the ‘‘Identification of
Nonattainment Classification and
Deadlines for Submission of SIP
Provisions for the 1997 PM 2.5 NAAQS
and 2006 PM 2.5 NAAQS’’ rule (the PM 2.5 Subpart 4 Classification and Deadline Rule). The rule identifies the classification under subpart 4 for areas currently designated nonattainment for
the 1997 annual and/or 2006 24-hour

PM 2.5 standards, and sets a new
deadline for states to submit attainmentrelated and other SIP elements required for these areas pursuant to subpart 4. The rule also identifies EPA guidance that is currently available regarding subpart 4 requirements. The PM 2.5 Subpart 4 Classification and Deadline Rule specifies December 31, 2014 as the deadline for the states to submit any
additional attainment-related SIPelements that may be needed to meet the applicable requirements of subpart 4 for areas currently designated
nonattainment for the 1997 annual and/
or 2006 24-hour PM 2.5 NAAQS and to submit SIPs addressing the nonattainment NSR requirements in subpart 4. Therefore, as explained in detail in the following section, since Pennsylvania submitted its request to redesignate the Reading Area for the
1997 annual PM 2.5 NAAQS on November 25, 2013, any additional
attainment-related SIP elements that may be needed for the Reading Area to meet the applicable requirements of subpart 4 were not due at the time that Pennsylvania submitted its redesignation request for the Area.

2. Proposal on This Issue

In this proposed rulemaking action,
EPA addresses the effect of the D.C. Circuit Court’s January 4, 2013 ruling and the June 2, 2014 PM 2.5 Subpart 4
Nonattainment Classification and Deadline Rule on the Reading Area redesignation request. EPA is proposing
to determine that the D.C. Circuit Court’s January 4, 2013 decision does not prevent EPA from redesignating the Reading Area to attainment. Even in light of the D.C. Circuit Court’s decision, redesignation for the Area is appropriate


### 76255 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

3 Applicable requirements of the CAA that come due subsequent to the area’s submittal of a complete redesignation request remain applicable until a redesignation is approved, but are not required as a prerequisite to redesignation. Section 175A(c) of
the CAA. under the CAA and EPA’s longstanding interpretations of the CAA provisions regarding redesignation. EPA first explains its longstanding interpretation that requirements that are imposed, or that become due, after a complete redesignation request is submitted for an area that is attaining the standard, are not applicable for purposes of evaluating a redesignation request. Second, EPA then shows that, even if EPA applies the subpart 4 requirements to the Reading Area redesignation request and disregards the provisions of
its 1997 annual PM 2.5 implementation rule remanded by the D.C. Circuit Court, the States’ request for redesignation of the Area still qualifies for approval.
EPA’s discussion takes into account the effect of the D.C. Circuit Court’s ruling and the June 2, 2014 PM 2.5 Subpart 4
Classification and Deadline Rule on the Area’s maintenance plan, which EPA views as approvable when subpart 4 requirements are considered.

a. Applicable Requirements Under Subpart 4 for Purposes of Evaluating the Reading Area Redesignation Request

With respect to the 1997 PM 2.5 Implementation Rule, the D.C. Circuit Court’s January 4, 2013 ruling rejected EPA’s reasons for implementing the

PM 2.5 NAAQS solely in accordance with the provisions of subpart 1, and remanded that matter to EPA, so that it could address implementation of the
1997 annual PM 2.5 NAAQS under subpart 4, in addition to subpart 1. For the purposes of evaluating the Commonwealth’s redesignation request for the Reading Area, to the extent that implementation under subpart 4 would impose additional requirements for areas designated nonattainment, EPA believes that those requirements are not ‘‘applicable’’ for the purposes of CAA section 107(d)(3)(E), and thus EPA is not required to consider subpart 4 requirements with respect to the redesignation of the Reading Area. Under its longstanding interpretation of the CAA, EPA has interpreted section 107(d)(3)(E) to mean, as a threshold matter, that the part D provisions which are ‘‘applicable’’ and which must be approved in order for EPA to redesignate an area include only those which came due prior to a state’s submittal of a complete redesignation request. See 1992 Calcagni
Memorandum. See also ‘‘State Implementation Plan (SIP) Requirements for Areas Submitting Requests for Redesignation to
Attainment of the Ozone and Carbon Monoxide (CO) National Ambient Air Quality Standards (NAAQS) on or after November 15, 1992,’’ Memorandum from Michael Shapiro, Acting Assistant Administrator, Air and Radiation, September 17, 1993 (Shapiro memorandum); Final Redesignation of Detroit-Ann Arbor, (60 FR 12459, 12465–66, March 7, 1995); Final Redesignation of St. Louis, Missouri, (68 FR 25418, 25424–27, May 12, 2003);
Sierra Club v. EPA, 375 F.3d 537, 541 (7th Cir. 2004) (upholding EPA’s redesignation rulemaking applying this interpretation and expressly rejecting Sierra Club’s view that the meaning of ‘‘applicable’’ under the statute is ‘‘whatever should have been in the plan
at the time of attainment rather than whatever actually was in the plan and already implemented or due at the time of attainment’’). 3 In this case, at the time that Pennsylvania submitted its November 25, 2013 redesignation request, the requirements under subpart
4 were not due.

EPA’s view that, for purposes of evaluating the redesignation of the Reading Area, the subpart 4 requirements were not due at the time
the Commonwealth submitted the redesignation request is in keeping with the EPA’s interpretation of subpart 2 requirements for subpart 1 ozone areas redesignated subsequent to the D.C.
Circuit Court’s decision in South Coast Air Quality Mgmt. Dist. v. EPA, 472 F.3d 882 (D.C. Cir. 2006). In South Coast, the
D.C. Circuit Court found that EPA was not permitted to implement the 1997 8- hour ozone standard solely under subpart 1, and held that EPA was required under the statute to implement the standard under the ozone-specific requirements of subpart 2 as well. Subsequent to the South Coast decision, in evaluating and acting upon redesignation requests for the 1997 8-
hour ozone standard that were
submitted to EPA for areas under subpart 1, EPA applied its longstanding interpretation of the CAA that ‘‘applicable requirements,’’ for purposes of evaluating a redesignation, are those
that had been due at the time the redesignation request was submitted. See, e.g., Proposed Redesignation of Manitowoc County and Door County Nonattainment Areas (75 FR 22047, 22050, April 27, 2010). In those actions, EPA, therefore, did not consider subpart 2 requirements to be ‘‘applicable’’ for the purposes of evaluating whether the area should be redesignated under section 107(d)(3)(E). EPA’s interpretation derives from the provisions of section 107(d)(3). Section 107(d)(3)(E)(v) states that, for an area to be redesignated, a state must meet ‘‘all requirements ‘applicable’ to the area under section 110 and part D.’’ Section 107(d)(3)(E)(ii) provides that the EPA must have fully approved the ‘‘applicable’’ SIP for the area seeking redesignation. These two sections read together support EPA’s interpretation of ‘‘applicable’’ as only those requirements that came due prior to submission of a complete redesignation request. First, holding states to an ongoing obligation to adopt new CAA requirements that
arose after the state submitted its redesignation request, in order to be redesignated, would make it problematic or impossible for EPA to act on redesignation requests in accordance with the 18-month deadline Congress
set for EPA action in section 107(d)(3)(D). If ‘‘applicable requirements’’ were interpreted to be a continuing flow of requirements with no reasonable limitation, states, after submitting a redesignation request, would be forced continuously to make
additional SIP submissions that in turn would require EPA to undertake further notice-and-comment rulemaking actions
to act on those submissions. This would create a regime of unceasing rulemaking that would delay action on the redesignation request beyond the 18- month timeframe provided by the CAA for this purpose.

Second, a fundamental premise for redesignating a nonattainment area to
attainment is that the area has attained the relevant NAAQS due to emission reductions from existing controls. Thus, an area for which a redesignation request has been submitted would have already attained the NAAQS as a result of satisfying statutory requirements that came due prior to the submission of the request. Absent a showing that unadopted and unimplemented requirements are necessary for future maintenance, it is reasonable to view the requirements applicable for purposes of evaluating the redesignation request as including only those SIP requirements that have already come due. These are the requirements that led to attainment of the NAAQS. To require, for redesignation approval, that a state also satisfy additional SIP requirements coming due after the state submits its complete redesignation request, and while EPA is reviewing it, would compel the state to do more than is necessary to attain the NAAQS, without a showing that the additional requirements are necessary for

maintenance.

4 Sierra Club v. Whitman was discussed and distinguished in a recent D.C. Circuit Court decision that addressed retroactivity in a quite different context, where, unlike the situation here, EPA sought to give its regulations retroactive effect. National Petrochemical and Refiners Ass’n v. EPA. 630 F.3d 145, 163 (D.C. Cir. 2010), rehearing denied 643 F.3d 958 (D.C. Cir. 2011), cert denied 132 S. Ct. 571 (2011). 5 PM 10 refers to particulates nominally 10
micrometers in diameter or smaller. 6 The potential effect of section 189(e) on section 189(a)(1)(A) for purposes of evaluating this redesignation is discussed in this rulemaking

action. In the context of this redesignation, the timing and nature of the D.C. Circuit Court’s January 4, 2013 decision in

NRDC v. EPA and EPA’s April 25, 2014

PM 2.5 Subpart 4 Nonattainment
Classification and Deadline Rule compound the consequences of imposing requirements that come due after the redesignation requests are submitted. Pennsylvania submitted its redesignation request for the 1997
annual PM 2.5 NAAQS on November 25, 2013, which is prior to the deadline by which the Reading Area is required to meet the applicable requirements pursuant to subpart 4.

To require the Pennsylvania’s fullycompleted and pending redesignation request for the 1997 annual PM 2.5 NAAQS to comply now with requirements of subpart 4 that the D.C. Circuit Court announced only in January, 2013 and for which the deadline to comply has not yet come, would be to give retroactive effect to such requirements and provide the Commonwealth a unique and earlier deadline for compliance solely on the basis of submitting its redesignation request for the Reading Area. The D.C. Circuit Court recognized the inequity of this type of retroactive impact in Sierra
Club v. Whitman, 285 F.3d 63 (D.C. Cir. 2002), 4 where it upheld the D.C. Circuit Court’s ruling refusing to make
retroactive EPA’s determination that the
St. Louis area did not meet its attainment deadline. In that case, petitioners urged the D.C. Circuit Court
to make EPA’s nonattainment
determination effective as of the date that the statute required, rather than the later date on which EPA actually made
the determination. The D.C. Circuit Court rejected this view, stating that applying it ‘‘would likely impose large costs on States, which would face fines and suits for not implementing air pollution prevention plans . . . even though they were not on notice at the

time.’’ Id. at 68. Similarly, it would be unreasonable to penalize the States by rejecting their redesignation request for an area that is already attaining the 1997
annual PM 2.5 standard and that met all applicable requirements known to be in effect at the time of the requests. For EPA now to reject the redesignation request solely because Pennsylvania did not expressly address subpart 4 requirements which have not yet come due, would inflict the same unfairness condemned by the D.C. Circuit Court in
Sierra Club v. Whitman.

b. Subpart 4 Requirements and Pennsylvania’s Redesignation Request

Even if EPA were to take the view that the D.C. Circuit Court’s January 4, 2013 decision requires that, in the context of pending redesignations for the 1997
annual PM 2.5 NAAQS, subpart 4 requirements were due and in effect at the time Pennsylvania submitted its redesignation request, EPA proposes to determine that the Reading Area still qualifies for redesignation to attainment
for the 1997 annual PM 2.5 NAAQS. As explained subsequently, EPA believes that the redesignation request for the Reading Area, though not expressed in terms of subpart 4 requirements, substantively meet the requirements of that subpart for purposes of redesignating the Area to attainment for
the 1997 annual PM 2.5 NAAQS.

With respect to evaluating the relevant substantive requirements of subpart 4 for purposes of redesignating the Reading Area, EPA notes that subpart 4 incorporates components of subpart 1 of part D, which contains general air quality planning requirements for areas designated as

nonattainment. See section 172(c). Subpart 4 itself contains specific planning and scheduling requirements for coarse particulate matter (PM 10 ) 5 nonattainment areas, and under the D.C. Circuit Court’s January 4, 2013 decision

in NRDC v. EPA, these same statutory requirements also apply for PM 2.5 nonattainment areas. EPA has longstanding general guidance that interprets the 1990 amendments to the CAA, making recommendations to states for meeting the statutory requirements
for SIPs for nonattainment areas. See,
the General Preamble. In the General Preamble, EPA discussed the relationship of subpart 1 and subpart 4 SIP requirements, and pointed out that subpart 1 requirements were to an extent ‘‘subsumed by, or integrally related to, the more specific PM 10 requirements’’ (57 FR 13538, April 16, 1992). The subpart 1 requirements include, among other things, provisions for attainment demonstrations, RACM, RFP, emissions inventories, and contingency measures.

For the purposes of this redesignation request, in order to identify any additional requirements which would apply under subpart 4, consistent with EPA’s June 2, 2014 PM 2.5 Subpart 4 Classification and Deadline Rule, EPA is considering the Reading Area to be a
‘‘moderate’’ PM 2.5 nonattainment area. As EPA explained in its June 2, 2014 rule, section 188 of the CAA provides that all areas designated nonattainment areas under subpart 4 are initially classified by operation of law as ‘‘moderate’’ nonattainment areas, and
remain moderate nonattainment areas
unless and until EPA reclassifies the

area as a ‘‘serious’’ nonattainment area. Accordingly, EPA believes that it is appropriate to limit the evaluation of the potential impact of subpart 4 requirements to those that would be applicable to moderate nonattainment areas. Sections 189(a) and (c) of subpart 4 apply to moderate nonattainment areas and include the following: (1) An approved permit program for construction of new and modified major stationary sources (section 189(a)(1)(A)); (2) an attainment demonstration (section 189(a)(1)(B)); (3) provisions for RACM (section 189(a)(1)(C)); and, (4) quantitative milestones demonstrating RFP toward attainment by the applicable attainment date (section 189(c)).

The permit requirements of subpart 4, as contained in section 189(a)(1)(A), refer to and apply the subpart 1 permit provisions requirements of sections 172
and 173 to PM 10 , without adding to them. Consequently, EPA believes that section 189(a)(1)(A) does not itself impose for redesignation purposes any additional requirements for moderate areas beyond those contained in subpart

1. 6 In any event, in the context of redesignation, EPA has long relied on the interpretation that a fully approved nonattainment NSR program is not considered an applicable requirement for redesignation, provided the area can maintain the standard with a prevention of significant deterioration (PSD) program after redesignation. A detailed
rationale for this view is described in a memorandum from Mary Nichols,
Assistant Administrator for Air and Radiation, dated October 14, 1994, entitled, ‘‘Part D NSR Requirements for Areas Requesting Redesignation to

Attainment.’’ See also rulemakings for Detroit, Michigan (60 FR 12467–12468,March 7, 1995); Cleveland-AkronLorain, Ohio (61 FR 20458, 20469– 20470, May 7, 1996); Louisville, Kentucky (66 FR 53665, October 23, 2001); and Grand Rapids, Michigan (61 FR 31834–31837, June 21, 1996).


### 76257 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

7 These attainment planning requirements include attainment demonstration, RFP, RACM, milestone requirements, contingency measures.

8 As EPA has explained above, we do not believe that the D.C. Circuit Court’s January 4, 2013 decision should be interpreted so as to impose these requirements on the states retroactively. Sierra Club

v. Whitman, supra.

With respect to the specific attainment planning requirements under subpart 4, 7 when EPA evaluates a redesignation request under either subpart 1 or 4, any area that is attaining
the PM 2.5 NAAQS is viewed as having satisfied the attainment planning requirements for these subparts. For redesignations, EPA has for many years interpreted attainment-linked requirements as not applicable for areas attaining the standard. In the General Preamble, EPA stated that: ‘‘The requirements for RFP will not apply in evaluating a request for redesignation to attainment since, at a minimum, the air quality data for the area must show that the area has already attained. Showing
that the State will make RFP towards attainment will, therefore, have no meaning at that point.’’

The General Preamble also explained that: ‘‘[t]he section 172(c)(9) requirements are directed at ensuring RFP and attainment by the applicable date. These requirements no longer apply when an area has attained the standard and is eligible for redesignation. Furthermore, section 175A for maintenance plans . . . provides specific requirements for contingency measures that effectively supersede the requirements of section 172(c)(9) for these areas.’’ Id. EPA similarly stated in its 1992 Calcagni Memorandum that, ‘‘The requirements for reasonable further progress and other
measures needed for attainment will not apply for redesignations because they only have meaning for areas not attaining the standard.’’

It is evident that even if we were to consider the D.C. Circuit Court’s January 4, 2013 decision in NRDC v. EPA to mean that attainment-related requirements specific to subpart 4 should be imposed retroactively 8 , or prior to December 13, 2014 and, thus, were due prior to Pennsylvania’s redesignation request, those requirements do not apply to an area that is attaining the 1997 annual PM 2.5 NAAQS, for the purpose of evaluating a pending request to redesignate the area to attainment. EPA has consistently enunciated this interpretation of applicable requirements under section 107(d)(3)(E) since the General Preamble was published more than twenty years ago. Courts have recognized the scope of EPA’s authority to interpret ‘‘applicable requirements’’ in the redesignation

context. See Sierra Club v. EPA, 375 F.3d 537 (7th Cir. 2004).

Moreover, even outside the context of redesignations, EPA has viewed the obligations to submit attainment-related SIP planning requirements of subpart 4 as inapplicable for areas that EPA determines are attaining the1997 annual

PM 2.5 NAAQS. EPA’s prior ‘‘Clean Data Policy’’ rulemakings for the PM 10 NAAQS, also governed by the requirements of subpart 4, explain EPA’s reasoning. They describe the
effects of a determination of attainment on the attainment-related SIP planning requirements of subpart 4. See
‘‘Determination of Attainment for Coso Junction Nonattainment Area,’’ (75 FR 27944, May 19, 2010). See also Coso Junction Proposed PM 10 Redesignation, (75 FR 36023, 36027, June 24, 2010); Proposed and Final Determinations of Attainment for San Joaquin Nonattainment Area (71 FR 40952, 40954–55, July 19, 2006; and 71 FR 63641, 63643–47, October 30, 2006). In short, EPA in this context has also long concluded that to require states to meet superfluous SIP planning requirements is not necessary and not required by the CAA, so long as those areas continue to attain the relevant NAAQS.

Elsewhere in this notice, EPA proposes to determine that the Reading
Area has attained and continues to
attain the 1997 annual PM 2.5 NAAQS. Under its longstanding interpretation, EPA is proposing to determine here thatthe Reading Area meets the attainmentrelated plan requirements of subparts 1
and 4 for the 1997 annual PM 2.5 NAAQS. Thus, EPA is proposing to conclude that all applicable requirements to submit an attainment demonstration under 189(a)(1)(B), a
RACM determination under section 172(c)(1) and section 189(a)(1)(c), a RFP demonstration under 189(c)(1), and contingency measure requirements under section 172(c)(9) are satisfied for purposes of evaluating this redesignation request.

c. Subpart 4 and Control of PM 2.5 Precursors

The D.C. Circuit Court in NRDC v. EPA remanded to EPA the two rules at
issue in the case with instructions to EPA to re-promulgate them consistent with the requirements of subpart 4. EPA
in this section addresses the D.C. Circuit Court’s opinion with respect to PM 2.5 precursors. While past implementation of subpart 4 for PM 10 has allowed for
control of PM 10 precursors such as NOx from major stationary, mobile, and area
sources in order to attain the standard as expeditiously as practicable, section 189(e) of the CAA specifically provides that control requirements for major stationary sources of direct PM 10 shall also apply to PM 10 precursors from those sources, except where EPA determines that major stationary sources of such precursors ‘‘do not contribute significantly to PM 10 levels which
exceed the standard in the area.’’

EPA’s 1997 PM 2.5 Implementation Rule, remanded by the D.C. Circuit Court, contained rebuttable presumptions concerning certain PM 2.5 precursors applicable to attainment plans and control measures related to those plans. Specifically, in 40 CFR 51.1002, EPA provided, among other things, that a state was ‘‘not required to address VOC [and ammonia] as . . .

PM 2.5 attainment plan precursor[s] and to evaluate sources of VOC [and ammonia] emissions in the State for
control measures.’’ EPA intended these to be rebuttable presumptions. EPA established these presumptions at the time because of uncertainties regarding
the emission inventories for these pollutants and the effectiveness of specific control measures in various regions of the country in reducing PM 2.5 concentrations. EPA also left open the possibility for such regulation of VOC
and NH 3 in specific areas where that

was necessary.

The D.C. Circuit Court in its January 4, 2013 decision made reference to both section 189(e) and 40 CFR 51.1002, and stated that, ‘‘In light of our disposition, we need not address the petitioners’ challenge to the presumptions in [40 CFR 51.1002] that VOCs and ammonia

are not PM 2.5 precursors, as subpart 4 expressly governs precursor presumptions.’’ NRDC v. EPA, at 27,

n.10.

Elsewhere in the D.C. Circuit Court’s opinion, however, the D.C. Circuit Court observed: ‘‘Ammonia is a precursor to fine particulate matter, making it a precursor to both PM 2.5 and PM 10 . For

a PM 10 nonattainment area governed by subpart 4, a precursor is presumptively regulated. See 42 U.S.C. 7513a(e) [section 189(e)].’’ Id. at 21, n.7.

For a number of reasons, EPA believes that its proposed redesignation of the Reading Area for the 1997 annual PM 2.5 NAAQS is consistent with the D.C. Circuit Court’s decision on this aspect of subpart 4. While the D.C. Circuit Court, citing section 189(e), stated that ‘‘for a

PM 10 area governed by subpart 4, a precursor is ‘presumptively regulated’,’’ the D.C. Circuit Court expressly declined to decide the specific challenge to EPA’s 1997 PM 2.5 Implementation Rule provisions regarding NH 3 and VOC as precursors.
The D.C. Circuit Court had no occasion


### 76258 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

9 Under either subpart 1 or subpart 4, for purposes of demonstrating attainment as expeditiously as practicable, a state is required to evaluate all economically and technologically
feasible control measures for direct PM emissions and precursor emissions, and adopt those measures that are deemed reasonably available. 10 The Reading Area has reduced VOC emissions through the implementation of various control programs including VOC Reasonably Available Control Technology (RACT) regulations and various
on-road and non-road motor vehicle control

programs. 11 See, e.g., ‘‘Approval and Promulgation of Implementation Plans for California—San Joaquin Valley PM 10 Nonattainment Area; Serious Area Plan
for Nonattainment of the 24-Hour and Annual PM 10 Standards,’’ (69 FR 30006, May 26, 2004) (approving a PM 10 attainment plan that impose
controls on direct PM 10 and NOx emissions and did not impose controls on SO 2 , VOC, or NH 3 emissions).

12 See, e.g., Assoc. of Irritated Residents v. EPA et al., 423 F.3d 989 (9th Cir. 2005). to reach whether and how it was substantively necessary to regulate any specific precursor in a particular PM 2.5 nonattainment area, and did not address what might be necessary for purposes of acting upon a redesignation request.

However, even if EPA takes the view that the requirements of subpart 4 were deemed applicable at the time the state submitted the redesignation request, and disregards the 1997 PM 2.5 Implementation Rule’s rebuttable presumptions regarding NH 3 and VOC

as PM 2.5 precursors, the regulatory consequence would be to consider the need for regulation of all precursors from any sources in the Area to demonstrate attainment and to apply the section 189(e) provisions to major stationary sources of precursors. In the case of the Reading Area, EPA believes that doing so is consistent with proposing redesignation of the Area for
the 1997 annual PM 2.5 NAAQS. The Reading Area has attained the 1997
annual PM 2.5 NAAQS without any specific additional controls of NH 3 and VOC emissions from any sources in the

Area.

Precursors in subpart 4 are specifically regulated under the provisions of section 189(e), which requires, with important exceptions, control requirements for major stationary sources of PM 10 precursors. 9 Under subpart 1 and EPA’s prior implementation rule, all major stationary sources of PM 2.5 precursors were subject to regulation, with the exception of NH 3 and VOC. Thus, EPA
must address here whether additional
controls of NH 3 and VOC from major stationary sources are required under section 189(e) of subpart 4 in order to redesignate the Area for the 1997 annual

PM 2.5 NAAQS. As explained subsequently, we do not believe that any additional controls of NH 3 and VOC are required in the context of this redesignation.

In the General Preamble, EPA discusses its approach to implementing section 189(e). See 57 FR 13538–13542. With regard to precursor regulation under section 189(e), the General Preamble explicitly stated that control of VOC under other CAA requirements may suffice to relieve a state from the need to adopt precursor controls under section 189(e). See 57 FR 13542. EPA in this rulemaking action, proposes to determine that Pennsylvania’s SIP has met the provisions of section 189(e) with respect to NH 3 and VOC as precursors. This proposed determination is based on our findings that: (1) The Reading Area contains no major stationary sources of NH 3, and (2) existing major stationary sources of VOC are adequately controlled under other provisions of the CAA regulating the ozone NAAQS. 10 In the alternative, EPA proposes to determine that, under the express exception provisions of section 189(e), and in the context of the redesignation of the Reading Area, which is attaining the 1997 annual

PM 2.5 NAAQS, at present NH 3 and VOC precursors from major stationary sources do not contribute significantly to levels exceeding the 1997 annual

PM 2.5 NAAQS in the Area. See 57 FR

13539–42.

EPA notes that its 1997 PM 2.5 Implementation Rule provisions in 40
CFR 51.1002 were not directed at
evaluation of PM 2.5 precursors in the context of redesignation, but at SIP plans and control measures required to bring a nonattainment area into
attainment of the 1997 annual PM 2.5 NAAQS. By contrast, redesignation to attainment primarily requires the nonattainment area to have already attained due to permanent and enforceable emission reductions, and to demonstrate that controls in place can
continue to maintain the standard. Thus, even if we regard the D.C. Circuit Court’s January 4, 2013 decision as calling for ‘‘presumptive regulation’’ of

NH 3 and VOC for PM 2.5 under the attainment planning provisions of subpart 4, those provisions in and of themselves do not require additional controls of these precursors for an area that already qualifies for redesignation. Nor does EPA believe that requiring Pennsylvania to address precursors differently than it has already would result in a substantively different

outcome.

Although, as EPA has emphasized, its consideration here of precursor requirements under subpart 4 is in the context of a redesignation to attainment, EPA’s existing interpretation of subpart 4 requirements with respect to precursors in attainment plans for PM 10 contemplates that states may develop attainment plans that regulate only those precursors that are necessary for purposes of attainment in the area in question, i.e., states may determine that only certain precursors need be regulated for attainment and control

purposes. 11 Courts have upheld this approach to the requirements of subpart
4 for PM 10

. 12 EPA believes that application of this approach to PM 2.5 precursors under subpart 4 is reasonable. Because the Reading Area has already attained the 1997 annual

PM 2.5 NAAQS with its current approach to regulation of PM 2.5 precursors, EPA believes that it is reasonable to conclude in the context of this redesignation that
there is no need to revisit the attainment control strategy with respect to the treatment of precursors. Even if the D.C.
Circuit Court’s decision is construed to impose an obligation, in evaluating this redesignation request, to consider additional precursors under subpart 4, it would not affect EPA’s approval here of Pennsylvania’s request for redesignation of the Reading Area for the 1997 annual

PM 2.5 NAAQS. In the context of a redesignation, the Area has shown that it has attained the standards. Moreover, Pennsylvania has shown and EPA has proposed to determine that attainment
of the 1997 annual PM 2.5 NAAQS in this Area is due to permanent and
enforceable emissions reductions on all precursors necessary to provide for
continued attainment of the standard ( see section V.A.3 of this rulemaking notice). It follows logically that no further control of additional precursors is necessary. Accordingly, EPA does not view the January 4, 2013 decision of the D.C. Circuit Court as precluding redesignation of the Reading Area to
attainment for the 1997 annual PM 2.5 NAAQS at this time. In summary, even if, prior to the date of the redesignation request submittal, Pennsylvania was required to address precursors for the Reading Area under subpart 4 rather than under subpart 1, as interpreted in
EPA’s remanded 1997 PM 2.5 Implementation Rule, EPA would still conclude that the Reading Area had met all applicable requirements for purposes of redesignation in accordance with section 107(d)(3(E)(ii) and (v) of the

CAA.

V. EPA’s Analysis of Pennsylvania’s SIP
Submittal

EPA is proposing several rulemaking actions for the Reading Area: (1) To redesignate the Area to attainment for


### 76259 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

the 1997 annual PM 2.5 NAAQS; (2) to approve into the Pennsylvania SIP, the associated maintenance plan for the
1997 annual PM 2.5 NAAQS; and, (3) to approve the 2007 comprehensive emissions inventory into the Pennsylvania SIP to satisfy section 172(c)(3) of the CAA requirement for the Area, one of the criteria for redesignation. EPA’s proposed approvals of the redesignation request and maintenance plan for the 1997
annual PM 2.5 NAAQS are based upon
EPA’s determination that the Area
continues to attain the 1997 annual

PM 2.5 NAAQS, which EPA is proposing in this rulemaking action, and that all other redesignation criteria have been met for the Reading Area. In addition, EPA is proposing to approve the 2017 and 2025 MVEBs for Berks County, Pennsylvania, for transportation conformity purposes. The following is a description of how the Pennsylvania November 25, 2013 submittal satisfies the requirements of section 107(d)(3)(E)
of the CAA for the 1997 annual PM 2.5 NAAQS.

A. Redesignation Request

1. Attainment

As noted previously, in the final rulemaking action dated July 29, 2011 (76 FR 45424), EPA determined that the Reading Area had attained the 1997
annual PM 2.5 NAAQS by its applicable
attainment date. EPA based this determination of attainment upon complete, quality-assured and certified ambient air quality monitoring data for the period of 2006–2008 showing that
the Area had attained the 1997 annual

PM 2.5 NAAQS. Further discussion of pertinent air quality issues underlying this determination was provided in the July 29, 2011 final rulemaking action for
EPA’s determination of attainment for
this Area.

Pennsylvania’s redesignation request
submittal includes the historic monitoring data for the annual PM 2.5 monitoring site in the Reading Area. The historic monitoring data shows that the Reading Area has attained and
continues to attain the 1997 PM 2.5 NAAQS. PADEP assures that all PM 2.5 monitoring data for the Reading Areahas been quality-assured, qualitycontrolled, and certified by the State in
accordance with 40 CFR 58.10. Furthermore, EPA has reviewed the most recent ambient air quality PM 2.5 monitoring data for PM 2.5 in the Reading Area, as submitted by the
Commonwealth and recorded in EPA’s Air Quality System (AQS). Table 1
shows the PM 2.5 quality-assured, quality-controlled, and state-certified 2008–2013 air quality data which indicates that the Reading Area
continues to attain the 1997 annual

PM 2.5 NAAQS. See the AQS design value reports dated April 16, 2014 and October 8, 2014 included in the docket for this proposed rulemaking action.

The Reading Area’s recent monitoring data supports EPA’s previous

determinations that the Area has

attained the 1997 annual PM 2.5 NAAQS. In addition, as discussed subsequently with respect to the Reading Area’s maintenance plan, the Commonwealth has committed to continue monitoring

ambient PM 2.5 concentrations in accordance with 40 CFR part 58. Thus, EPA is proposing to determine that the Reading Area continues to attain the

1997 annual PM 2.5 NAAQS.

2. The Area Has Met All Applicable Requirements Under Section 110 and Subpart 1 of the CAA and Has a Fully Approved SIP Under Section 110(k) of

the CAA

In accordance with section 107(d)(3)(E)(v) of the CAA, the SIP

revisions for the 1997 annual PM 2.5 NAAQS for the Reading Area must be fully approved under section 110(k) of the CAA and all the requirements applicable to the Area under section 110 of the CAA (general SIP requirements) and part D of Title I of the CAA (SIP requirements for nonattainment areas)

must be met. a. Section 110 General SIP Requirements

Section 110(a)(2) of Title I of the CAA delineates the general requirements for a SIP, which include enforceable
emissions limitations and other control measures, means, or techniques, provisions for the establishment and operation of appropriate devices necessary to collect data on ambient air quality, and programs to enforce the limitations. The general SIP elements and requirements set forth in section 110(a)(2) of the CAA include, but are not limited to, the following: (1) Submittal of a SIP that has been adopted by the state after reasonable public notice and hearing; (2) provisions for establishment and operation of appropriate procedures needed to monitor ambient air quality; (3) implementation of a source permit program; provisions for the implementation of Part C requirements (PSD); (4) provisions for the implementation of Part D requirements for NSR permit programs; (5) provisions for air pollution modeling; and, (6) provisions for public and local agency participation in planning and emission control rule development.

Section 110(a)(2)(D) of the CAA requires that SIPs contain certain measures to prevent sources in a state from significantly contributing to air quality problems in another state. To implement this provision, EPA has required certain states to establish programs to address the interstate transport of air pollutants in accordance
with the NO X SIP Call (63 FR 57356, October 27, 1998), amendments to the

NO X SIP Call (64 FR 26298, May 14, 1999 and 65 FR 11222, March 2, 2000), and CAIR (70 FR 25162, May 12, 2005). However, section 110(a)(2)(D) of the CAA requirements for a state are not linked with a particular nonattainment area’s designation and classification in
that state. EPA believes that the requirements linked with a particular nonattainment area’s designation and
classifications are the relevant measures to evaluate in reviewing a redesignation request. The transport SIP submittal requirements, where applicable, continue to apply to a state regardless of the designation of any one particular area in the state. Thus, EPA does not believe that these requirements are applicable requirements for purposes of redesignation.

In addition, EPA believes that the other section 110(a)(2) elements of the
CAA not connected with nonattainment plan submissions and not linked with

an area’s attainment status are not applicable requirements for purposes of


### 76260 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

13 This regulation was promulgated as part of the

1997 PM 2.5 NAAQS implementation rule that was subsequently challenged and remanded in NRDC v. EPA, 706 F.3d 428 (D.C. Cir. 2013), as discussed in
Section VI of this notice. However, the Clean Data Policy portion of the implementation rule was not

at issue in that case. redesignation. The Reading Area will still be subject to these requirements after it is redesignated. EPA concludes that section 110(a)(2) of the CAA and part D requirements which are linked with a particular area’s designation and
classification are the relevant measures to evaluate in reviewing a redesignation request, and that section 110(a)(2)
elements of the CAA not linked in the

area’s nonattainment status are not applicable for purposes of redesignation. This approach is consistent with EPA’s existing policy on applicability of conformity ( i.e., for redesignations) and oxygenated fuels requirement. See Reading, Pennsylvania, proposed and final rulemakings (61 FR 53174, October 10, 1996 and 62 FR 24826, May 7, 1997); Cleveland-Akron-Lorain, Ohio final rulemaking (61 FR 20458, May 7, 1996); and Tampa, Florida final rulemaking (60 FR 62748, December 7, 1995). See also
the discussion on this issue in the Cincinnati, Ohio redesignation (65 FR 37890, June 19, 2000) and in the Pittsburgh, Pennsylvania redesignation (66 FR 53099, October 19, 2001).

EPA has reviewed the Pennsylvania
SIP and has concluded that it meets the general SIP requirements under section 110(a)(2) of the CAA to the extent they are applicable for purposes of redesignation. EPA has previously approved provisions of Pennsylvania’s SIP addressing section 110(a)(2) requirements, including provisions addressing PM 2.5

. See 76 FR 47062, August 4, 2011. These requirements are, however, statewide requirements that
are not linked to the PM 2.5 nonattainment status of the Reading Area. Therefore, EPA believes that these SIP elements are not applicable requirements for purposes of review of Pennsylvania’s PM 2.5 redesignation request.

b. Subpart 1 Requirements

Subpart 1 sets forth the basic nonattainment plan requirements applicable to PM 2.5 nonattainment areas. Under section 172 of the CAA, states
with nonattainment areas must submit plans providing for timely attainment and meet a variety of other requirements. The General Preamble for Implementation of Title I discusses the evaluation of these requirements in the
context of EPA’s consideration of a redesignation request. The General
Preamble sets forth EPA’s view of applicable requirements for purposes of evaluating redesignation requests when an area is attaining the standard. See 57 FR 13498, April 16, 1992.

As noted previously, EPA has determined that the Reading Area has
attained the 1997 annual PM 2.5 NAAQS. EPA’s longstanding interpretation of the nonattainment planning requirements of
section 172 is that once an area is attaining the NAAQS, those requirements are not ‘‘applicable’’ for purposes of CAA section 107(d)(3)(E)(ii) and, therefore, need not be approved into the SIP before EPA can redesignate
the area. In the 1992 General Preamble for Implementation of Title I, EPA set forth its interpretation of applicable requirements for purposes of evaluating redesignation requests when an area is attaining a standard. See 57 FR 13498, 13564 (April 16, 1992). EPA noted that the requirements for reasonable further progress and other measures designed to provide for attainment do not apply in evaluating redesignation requests because those nonattainment planning requirements ‘‘have no meaning’’ for an area that has already attained the
standard. Id. This interpretation was also set forth in the Calcagni Memorandum. EPA’s understanding of
section 172 also forms the basis of its Clean Data Policy, which was articulated with regard to PM 2.5 in 40 CFR 51.1004(c), and suspends a state’s obligation to submit most of the attainment planning requirements that would otherwise apply, including an attainment demonstration and planning SIPs to provide for reasonable further progress (RFP), RACM, and contingency measures under section 172(c)(9). 13 Courts have upheld EPA’s interpretation of section 172(c)(1)’s ‘‘reasonably
available’’ control measures and control technology as meaning only those controls that advance attainment, which precludes the need to require additional measures where an area is already attaining. NRDC v. EPA, 571 F.3d 1245, 1252 (D.C. Cir. 2009); Sierra Club v. EPA, 294 F.3d 155, 162 (D.C. Cir. 2002);
Sierra Club v. EPA, 314 F.3d 735, 744 (5th Cir. 2002).

Therefore, because attainment has been reached in the Reading Area, no
additional measures are needed to provide for attainment, and section 172(c)(1) requirements for an attainment demonstration and RACM are no longer considered to be applicable for purposes of redesignation as long as the Area
continues to attain the standard until redesignation. The section 172(c)(2) requirement that nonattainment plans contain provisions promoting reasonable further progress toward
attainment is also not relevant for purposes of redesignation because EPA has determined that the Reading Area
has monitored attainment of the 1997
annual PM 2.5 NAAQS. In addition, because the Reading Area has attained
the 1997 annual PM 2.5 NAAQS and is no longer subject to an RFP requirement, the requirement to submit the section 172(c)(9) contingency measures is not applicable for purposes of redesignation. Section 172(c)(6) requires
the SIP to contain control measures necessary to provide for attainment of the NAAQS. Because attainment has been reached, no additional measures are needed to provide for attainment.

The requirement under section 172(c)(3) was not suspended by EPA’s
clean data determination for the 1997
annual PM 2.5 NAAQS, and is the only remaining requirement under section
172 of the CAA to be considered for purposes of redesignation of the Reading Area. Section 172(c)(3) of the CAA requires submission and approval of a comprehensive, accurate and current inventory of actual emissions. As part of Pennsylvania’s redesignation request submittal, the Commonwealth submitted a 2007 base year emissions inventory for the Reading Area for the
1997 annual PM 2.5 NAAQS which
includes emissions estimates that cover the general source categories of point sources, nonroad mobile sources, area sources, and on-road mobile sources. The pollutants that comprise the inventory are NO X , SO 2 , PM 2.5 , VOC,
and NH 3

.

In this rulemaking action, EPA is proposing to approve the Reading Area 2007 base year emissions inventory in accordance with section 172(c)(3) of the CAA. Final approval of the 2007 base year emissions inventory will satisfy the emissions inventory requirement under section 172(c)(3) of the CAA. For more information on the development of the 2007 base year emissions inventory, see Appendix C of the Commonwealth’s submittal, and, for information on EPA’s analysis, see the emissions inventory technical support document (TSD) dated April 18, 2014, both available in the docket for this proposed rulemaking action. A summary of the 2007 base year emissions inventory is shown in Table

Section 172(c)(4) of the CAA requires the identification and quantification of allowable emissions for major new and modified stationary sources in an area, and section 172(c)(5) of the CAA requires source permits for the construction and operation of new and modified major stationary sources anywhere in the nonattainment area. EPA has determined that, since the PSD requirements will apply after redesignation, areas being redesignated need not comply with the requirement that a nonattainment NSR program be approved prior to redesignation, provided that the area demonstrates maintenance of the NAAQS without part D NSR. A more detailed rationale
for this view is described in a memorandum from Mary Nichols,
Assistant Administrator for Air and Radiation, dated October 14, 1994 entitled, ‘‘Part D NSR Requirements for Areas Requesting Redesignation to Attainment.’’ Nevertheless, Pennsylvania currently has an approved NSR program, codified in Pa. Chapter 127, Subchapter E. See 77 FR 41276, August 13, 2012 (approving NSR revisions into the SIP). However, Pennsylvania’s PSD program for the
1997 annual PM 2.5 NAAQS will become effective in the Reading Area upon redesignation to attainment. See 49 FR 33128, August 21, 1984 (approving PSD program into the SIP).

Section 172(c)(7) of the CAA requires the SIP to meet the applicable provisions of section 110(a)(2) of the CAA. As noted previously, EPA believes the Pennsylvania SIP meets the requirements of section 110(a)(2) of the CAA that are applicable for purposes of redesignation. Section 175A of the CAA requires a state seeking redesignation to
attainment to submit a SIP revision to provide for the maintenance of the NAAQS in the area ‘‘for at least 10 years after the redesignation.’’ In conjunction with its request to redesignate the Reading Area to attainment status, Pennsylvania submitted SIP revisions to provide for maintenance of the 1997
annual PM 2.5 NAAQS in the Area through 2025, which is at least 10 years after redesignation. Pennsylvania is requesting that EPA approve this SIP revision as meeting the requirement of
section 175A of the CAA. Once approved, the maintenance plan for the Reading Area will ensure that the SIP for Pennsylvania meets the requirements of the CAA regarding
maintenance of the 1997 annual PM 2.5 NAAQS for the Area. EPA’s analysis of the maintenance plan is provided in subsection B of section V (Maintenance Plan) of today’s proposed rulemaking

action.

Section 176(c) of the CAA requires
states to establish criteria and procedures to ensure that Federally supported or funded projects conform to the air quality planning goals in the applicable SIP. The requirement to determine conformity applies to transportation plans, programs, and projects developed, funded or approved
under Title 23 of the United States Code (U.S.C.) and the Federal Transit Act (transportation conformity) as well as to all other Federally supported or funded projects (general conformity). State transportation conformity SIP revisions
must be consistent with Federal conformity regulations relating to consultation, enforcement and enforceability which EPA promulgated pursuant to its authority under the CAA. EPA approved Pennsylvania’s transportation conformity SIP requirements on April 29, 2009 (74 FR 19541). Thus, for purposes of redesignating the Reading Area to
attainment for the 1997 annual PM 2.5 NAAQS, EPA determines that upon final approval of the 2007 comprehensive emissions inventory as proposed in this rulemaking action, the Reading Area will meet all applicable SIP requirements under part D of Title I of the CAA for purposes of redesignating the Area to attainment.

c. Pennsylvania Has a Fully Approved Applicable SIP Under Section 110(k) of
the CAA

Upon final approval of the 2007 comprehensive emissions inventory proposed in this rulemaking action, EPA will have fully SIP-approved all applicable requirements of the Pennsylvania SIP for the Area for purposes of redesignaton to attainment
for the 1997 annual PM 2.5 NAAQS in accordance with section 110(k) of the CAA. As noted above, in this rulemaking action, EPA is proposing to approve the Reading Area 2007 emissions inventory (submitted as part of its maintenance plan) as meeting the requirement of section 172(c)(3) of the
CAA for the 1997 annual PM 2.5 NAAQS. Therefore, upon final approval of the 2007 emissions inventory, EPA will have satisfied all applicable requirements under part D of Title I of the CAA for the Reading Area.

3. Permanent and Enforceable
Reductions in Emissions

For redesignating a nonattainment area to attainment, section 107(d)(3)(E)(iii) of the CAA requires EPA to determine that the air quality improvement in the area is due to permanent and enforceable reductions in emissions resulting from implementation of the SIP and applicable Federal air pollution control regulations and other permanent and enforceable reductions. In making this demonstration, Pennsylvania has calculated the change in emissions between 2002, one of the years used to designate the Area as nonattainment, and 2007, one of the years the Area monitored attainment, as shown in
Table 3.

It should be noted that the 2002 inventory for PM 2.5 did not include condensible emissions for many stationary point sources in the Commonwealth, and that the 2007 inventory was later augmented to
include calculated condensible emissions for EGUs, resulting in an apparent increase of PM 2.5 emissions in 2007 for stationary point source emissions. Similarly, emissions of NO X and SO 2 for stationary and area sources
show small increases in 2007. Nevertheless, the Area was able to attain the standard during the time period that included 2007, as decreases in other precursors more than compensated for any increases.

The reduction in emissions and the corresponding improvement in air quality from 2002 to 2007 in the Reading Area can be attributed to a number of regulatory control measures that have been implemented in the Area and contributing areas in recent years. For more information on EPA’s analysis
of the 2002 and 2007 emissions inventory, see EPA’s emissions inventory TSD dated April 18, 2014, available in the docket for this proposed rulemaking action.

a. Federal Measures Implemented

Reductions in PM 2.5 precursor emissions have occurred statewide and in upwind states as a result of Federal emission control measures, with additional emission reductions expected
to occur in the future. Data collected from EPA’s long-term national air quality and deposition monitoringnetworks show that these regional capand-trade programs have been effective in reducing emissions of SO 2 and NO X nationwide. 14 NO X SIP Call

On October 27, 1998 (63 FR 57356),
EPA issued the NO X SIP Call requiring
the District of Columbia and 22 states to
reduce emissions of NO X , a precursor to ozone pollution. 15 Affected states were required to comply with Phase I of the SIP Call beginning in 2004 and Phase II beginning in 2007. Emission reductions resulting from regulations developed in response to the NO X SIP Call are permanent and enforceable. By imposing an emissions cap regionally,
the NO X SIP Call reduced NO X emissions from large EGUs and large non-EGUs such as industrial boilers, internal combustion engines, and cement kilns. In response to the NO X SIP Call, Pennsylvania adopted its NO X Budget Trading Program regulations for EGUs and large industrial boilers, with emission reductions starting in May


### 76263 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

2003. Pennsylvania’s NO X Budget Trading Program regulation was approved into the Pennsylvania SIP on August 21, 2001 (66 FR 43795). To meet other requirements of the NO X SIP Call, Pennsylvania adopted NO X control regulations for cement plants and internal combustion engines, with emission reductions starting in May 2005. These regulations were approved into the Pennsylvania SIP on September 29, 2006 (71 FR 57428).

CAIR

As previously noted, CAIR (70 FR 25162, May 12, 2005) created regional cap-and-trade programs to reduce SO 2 and NO X emissions in 27 eastern states, including Pennsylvania. EPA approved the Commonwealth’s CAIR regulation, codified in 25 Pa. Code Chapter 145, Subchapter D, into the Pennsylvania SIP on December 10, 2009 (74 FR 65446). In 2009, the CAIR ozone season NO X trading program superseded the NO X Budget Trading Program, although the emission reduction obligations of the

NO X SIP Call were not rescinded. See 40 CFR 51.121(r) and 51.123(aa). As of this proposal, CAIR remains in the Pennsylvania SIP. However, EPA promulgated CSAPR to replace CAIR as an emission trading program for EGUs. As discussed previously, pursuant to the D.C. Circuit’s October 23, 2014 Order, the stay of CSAPR has been lifted and implementation of CSAPR will commence in January 2015. EPA expects that the implementation of CSAPR will preserve the reductions achieved by CAIR and result in
additional SO 2 and NO X emission reductions throughout the maintenance period

Tier 2 Emission Standards for Vehicles
and Gasoline Sulfur Standards

These emission control requirements
result in lower NO X emissions from new cars and light duty trucks, including sport utility vehicles. The Federal rules were phased in between 2004 and 2009. EPA estimated that, after phasing in the new requirements, the following vehicle

NO X emission reductions will have occurred nationwide: Passenger cars (light duty vehicles) (77 percent); light duty trucks, minivans, and sports utility vehicles (86 percent); and larger sports utility vehicles, vans, and heavier trucks (69 to 95 percent). Some of the emissions reductions resulting from new vehicle standards occurred during the 2008–2010 attainment period; however, additional reductions will continue to occur throughout the maintenance period as new vehicles replace older vehicles. EPA expects fleet wide average emissions to decline by similar percentages as new vehicles replace older vehicles.

Heavy-Duty Diesel Engine Rule

EPA issued the Heavy-Duty Diesel Engine Rule in July 2000. This rule included standards limiting the sulfur content of diesel fuel, which went into effect in 2004. A second phase took
effect in 2007 which reduced PM 2.5 emissions from heavy-duty highway engines and further reduced the highway diesel fuel sulfur content to 15 ppm. Standards for gasoline engines were phased in starting in 2008. The total program is estimated to achieve a 90 percent reduction in direct PM 2.5 emissions and a 95 percent reduction in

NO X emissions for new engines using
low sulfur diesel fuel.

Nonroad Diesel Rule

On June 29, 2004 (69 FR 38958), EPA promulgated the Nonroad Diesel Rule for large nonroad diesel engines, such as those used in construction, agriculture, and mining, to be phased in between 2008 and 2014. The rule phased in requirements for reducing the sulfur
content of diesel used in nonroad diesel engines. The reduction in sulfur content prevents damage to the more advanced emission control systems needed to meet the engine standards. It will also reduce fine particulate emissions from diesel engines. The combined engine
standards and the sulfur in fuel
reductions will reduce NO X and PM emissions from large nonroad engines by over 90%, compared to current nonroad engines using higher sulfur
content diesel.

Nonroad Large Spark-Ignition Engine and Recreational Engine Standards

In November 2002, EPA promulgated emission standards for groups of previously unregulated nonroad engines. These engines include large spark-ignition engines such as thoseused in forklifts and airport groundservice equipment; recreational vehiclesusing spark-ignition engines such as offhighway motorcycles, all-terrain vehicles, and snowmobiles; and recreational marine diesel engines.Emission standards from large sparkignition engines were implemented in two tiers, with Tier 1 starting in 2004 and Tier 2 starting in 2007. Recreational vehicle emission standards are being phased in from 2006 through 2012. Marine Diesel engine standards were phased in from 2006 through 2009. With full implementation of all of the nonroad spark-ignition engine and recreational engine standards, an overall 80 percent reduction in NO X are expected by 2020. Some of these emission reductions occurred by the 2002–2007 attainment period and
additional emission reductions will occur during the maintenance period as
the fleet turns over.

Federal Standards for Hazardous Air
Pollutants

As required by the CAA, EPA developed Maximum Available Control Technology (MACT) Standards to regulate emissions of hazardous air pollutants from a published list of
industrial sources referred to as ‘‘source categories.’’ The MACT standards have been adopted and incorporated by
reference in Section 6.6 of Pennsylvania’s Air Pollution Control Act and implementing regulations in 25 Pa. Code § 127.35 and are also included in Federally enforceable permits issued by PADEP for affected sources. The
Industrial/Commercial/Institutional (ICI) Boiler MACT standards (69 FR 55217, September 13, 2004, and 76 FR 15554, February 21, 2011) are estimated to reduce emissions of PM, SO 2 , and VOCs from major source boilers and process heaters nationwide. Also, the Reciprocating Internal Combustion Engines (RICE) MACT will reduce NO X and PM emissions from engines located at facilities such as pipeline compressor stations, chemical and manufacturing plants, and power plants.

b. State Measures

Heavy-Duty Diesel Emissions Control Program

In 2002, Pennsylvania adopted the Heavy-Duty Diesel Emissions Control Program for model years starting in May 2004. The program incorporates California standards by reference and required model year 2005 and beyond heavy-duty diesel highway engines to be certified to the California standards, which were more stringent than the Federal standards for model years 2005 and 2006. After model year 2006, Pennsylvania required implementation of the Federal standards that applied to model years 2007 and beyond,
discussed in the Federal measures section of this proposed rulemaking action. This program results in reduced
emissions of NO X statewide.

Vehicle Emission Inspection/ Maintenance (I/M) program

Pennsylvania’s Vehicle Emission I/M program was expanded into the Reading Area in early 2004, and applies to model year 1975 and newer gasoline-powered vehicles that are 9,000 pounds and under. The program, approved into the Pennsylvania SIP on October 6, 2005 (70 FR 58313), consists of annual on-board diagnostics and gas cap test for model


### 76264 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

year 1996 vehicles and newer, and an annual visual inspection of pollution control devices and gas cap test for model year 1995 vehicles and older. This program reduces emissions of NO X from affected vehicles.

Consumer Products Regulation

Pennsylvania regulation ‘‘Chapter 130, Subchapter B. Consumer Products’’
established VOC emission limits [effective January 1, 2005] for numerous categories of consumer products, and applies statewide to any person who sells, supplies, offers for sale, or manufactures such consumer products on or after January 1, 2005 for use in Pennsylvania. It was approved into the Pennsylvania SIP on December 8, 2004 (69 FR 70895).

Based on the information summarized above, Pennsylvania has adequately demonstrated that the improvement in air quality in the Reading Area is due to permanent and enforceable emissions
reductions. The reductions result from Federal and State requirements and regulation of precursors within Pennsylvania that affect the Reading

Area.

B. Maintenance Plan

On November 25, 2013, PADEP submitted a maintenance plan for the Reading Area for the 1997 annual PM 2.5 NAAQS as required by section 175A of the CAA. EPA’s analysis for proposing approval of the maintenance plan is provided in this section.

1. Attainment Emissions Inventory

Section 172(c)(3) requires states to submit a comprehensive, accurate, current inventory of actual emissions
from all sources in the nonattainment area. For a maintenance plan, states are required to submit an inventory to identify the level of emissions in the
area which is sufficient to attain the NAAQS, referred to as the attainment inventory (or the maintenance plan base year inventory), and which should be
based on actual emissions. PADEP submitted an attainment inventory for 2007, one of the years in the period during which the Reading Area
monitored attainment of the 1997
annual PM 2.5 standard, comprised of

NO X , PM 2.5 , SO 2 , VOC, and NH 3 emissions from point sources, nonpoint sources, onroad mobile sources, and
nonroad mobile sources.

The 2007 point source inventory
contained emissions for EGU and nonEGU sources in Berks County that were directly reported by the facilities. Since the reported emissions did not include condensible emissions, the EGU inventory was augmented to account for condensibles by application of emission factors developed for the Mid-Atlantic Regional Air Management Association (MARAMA) in 2008.

The nonpoint source emissions inventory for 2007 was developed using 2007 specific activity data along with
EPA emission factors and the most recently available emission calculation methodologies. PADEP used 2008 National Emissions Inventory (NEI) data to fill in any missing categories in the 2007 inventory.

For 2007 nonroad mobile sources, PADEP generated emissions using EPA’s National Mobile Inventory Model (NMIM) 2008 model. Since marine, air and rail/locomotive (MAR) emissions are not part of the NONROAD model, they were calculated separately outside
of the NONROAD model.

The 2007 onroad mobile source inventory was developed using EPA’s highway mobile source emissions model MOVES2010. PADEP used local acivity to replace default inputs in the model where appropriate.

EPA has reviewed the documentation provided by PADEP and found the 2007 emissions inventory acceptable for meeting the requirements under section 172(c)(3). For more information on the emissions inventories submitted by PADEP for the Reading Area and EPA’s analysis of the inventories, see Appendix B of the Commonwealth’s
submittal and see also EPA’s TSD dated April 18, 2014, both of which are available in the docket for this proposed rulemaking action.

2. Maintenance Demonstration

Section 175A requires a state seeking redesignation to attainment to submit a SIP revision to provide for the maintenance of the NAAQS in the area ‘‘for at least 10 years after the redesignation.’’ EPA has interpreted this as a showing of maintenance ‘‘for a period of ten years following redesignation.’’ Where the emissions inventory method of showing maintenance is used, its purpose is to show that emissions during the maintenance period will not increase over the attainment year inventory. See 1992 Calcagni Memorandum, pages 9–

10.

For a demonstration of maintenance, emissions inventories are required to be projected to future dates to assess the influence of future growth and controls; however, the maintenance
demonstration need not be based on modeling. See Wall v. EPA, supra;
Sierra Club v. EPA, supra. See also 66 FR 53099–53100; 68 FR 25430–32. PADEP uses projection inventories to
show that the Area will remain in attainment and developed projection inventories for an interim year of 2017 and a maintenance plan end year of
2025 to show that future emissions of

NO X , SO 2, VOC, and PM 2.5 will remain at or below the attainment year 2007 emissions levels throughout the Area through the year 2025. Although
emissions of NH 3 are projected to
increase from 2007 to 2017 and from 2007 to 2025, the increase will not affect the Area’s ability to maintain the
standard because such increases are more than compensated by the significant reductions of the other precursors that are projected during the maintenance period.

The Federal and State measures
described in Section V.A.3. of this proposed rulemaking action
demonstrate that the reductions in emissions from point, area, and mobile
sources in the Area have occurred and will continue to occur through 2025. In addition, the following State and Federal regulations and programs ensure the continuing decline of SO 2 , NO X , PM 2.5 , and VOC emissions in the Area during the maintenance period and beyond:

Non-EGUs previously covered under the
NOx SIP Call

Pennsylvania established NO X emission limits for the large industrial boilers that were previously subject to
the NO X SIP Call, but were not subject to CAIR. For these units, Pennsylvania
established an allowable ozone season

NO X limit based on the unit’s previous ozone season’s heat input. A combined

NO X ozone season emissions cap of 3,418 tons applies for all of these units.

Regulation of Cement Kilns

On July 19, 2011 (76 FR 52558), EPA approved amendments to 25 Pa. Code Chapter 145 Subchapter C to further
reduce NO X emissions from cement
kilns. The amendments established NO X emission rate limits for long wet kilns, long dry kilns, and preheater and precalciner kilns that are lower by 35% to 63% from the previous limit of 6 pounds of NO X per ton of clinker that applied to all kilns. The amendments became effective on April 15, 2011.

Stationary Source VOC Regulations

Pennsylvania regulation 25 Pa. Code Chapter 130, Subchapter D for Adhesives, Sealers, Primers, and Solvents was approved into the Pennsylvania SIP on September 26, 2012 (77 FR 59090). The regulation
established VOC content limits for various categories of adhesives, sealants, primers, and solvent, and became applicable on January 1, 2012.


### 76265 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

Amendments to Pennsylvania regulation 25 Pa. Code Chapter 130, Subchapter B established, effective January 1, 2009, new or more stringent VOC standards for consumer products. The amendments were approved into the Pennsylvania SIP on October 18, 2010 (75 FR 63717).

Pennsylvania’s Clean Vehicle Program

The Pennsylvania Clean Vehicles Program (formerly, New Motor Vehicle Control Program) incorporates by
reference the California Low Emission Vehicle program (CA LEVII), although it allowed automakers to comply with the National Low Emission Vehicle (NLEV) program as an alternative to this program until Model Year (MY) 2006. The Clean Vehicles Program, codified in 25 Pa. Code Chapter 126, Subchapter D, was modified to require CA LEVII to apply to MY 2008 and beyond, and was approved into the Pennsylvania SIP on January 24, 2012 (77 FR 3386). The Clean Vehicles Program incorporates by
reference the emission control standards of CA LEVII, which, among other requirements, reduces emissions of NO X by requiring that passenger car emission standards and fleet average emission standards also apply to light duty vehicles. Model year 2008 and newer passenger cars and light duty trucks are required to be certified for emissions by
the California Air Resource Board (CARB), in order to be sold, leased, offered for sale or lease, imported, delivered, purchased, rented, acquired, received, titled or registered in Pennsylvania. In addition, manufacturers are required to
demonstrate that the California fleet average standard is met based on the number of new light-duty vehicles
delivered for sale in the
Commonwealth. The Commonwealth’s submittal for the January 24, 2012 rulemaking projected that, by 2025, the program will achieve almost 40 tons

more NO X reductions than Tier II for the counties in the Reading Area.

Two Pennsylvania regulations— Diesel-Powered Motor Vehicle Idling Act (approved into the Pennsylvania SIP on August 1, 2011, See 76 FR 45705)
and Outdoor Wood-Fired Boiler regulation (approved into the Pennsylvania SIP on September 20,

2011, see 76 FR 58114)—were not included in the projection inventories, but may also assist in maintaining the
1997 annual PM 2.5 NAAQS. Also, EPA’s
Tier 3 Motor Vehicle Emission and Fuel Standards ( See 79 FR 23414, April 28, 2014) establishes more stringent vehicle
emissions standards and will reduce the sulfur content of gasoline beginning in
2017. This fuel standard will achieve

NO X reductions by further increasing
the effectiveness of vehicle emission controls for both existing and new vehicles. Finally, with the lifting of the CSAPR stay by the DC Circuit Court on October 23, 3014, the implementation of CSAPR will preserve the reductions achieved by CAIR and will achieve
additional emission reductions in the Area from upwind states.

The projection inventories for the 2017 and 2025 point, area, and nonroad sources were taken from regional inventories coordinated by MARAMA
for the states in the Mid-Atlantic/ Northeast Visibility Union and Virginia (MANE–VU+VA), which includes Pennsylvania. Detailed discussion of how 2017 and 2025 projections were developed are contained in Appendix C–2 and C–3, respectively, of the
Commonwealth’s submittal. EPA has reviewed the documentation provided by PADEP and found the methodologies acceptable.

EPA has determined that the 2017 and 2025 projected emissions inventories provided by PADEP are approvable. For detailed information on the projected inventories, see Appendices A–3, B–3, D–2, and E–3 of the State submittal, and for more information on EPA’s analysis of the emissions inventory, see EPA’s TSD dated April 18, 2014, both of which
are available in the docket for this proposed rulemaking action. Table 4 provides a summary of the inventories for the 2007 attainment year, as compared to the projected inventories for the 2017 interim year and the 2025 maintenance plan end year for the Area.

As shown in Table 4, the projected
levels of PM 2.5 , NO X , SO 2 , and VOC are under the 2007 attainment year levels for each of these pollutants. While the
emissions of NH 3 are projected to be higher than the 2007 inventory for this pollutant for both the interim year and the end-year, the decreases in the other precursors, particularly the significant
reductions in NO X , more than compensate for the increase, therefore,
the increase in NH 3 is not considered to affect the Area’s ability to maintain the NAAQS. The projected emissions
inventories show that the Area will
continue to maintain the 1997 annual

PM 2.5 NAAQS during the 10 year maintenance period. Moreover, the modeling analysis conducted for the Regulatory Impact Analysis (RIA) for the

2012 PM 2.5 NAAQS indicates that the
annual PM 2.5 design value for this Area is expected to continue to decline through 2020. Given the significant decrease in overall precursor emissions projected through 2025, it is reasonable
to conclude that monitored PM 2.5 levels
in this area will also continue to decrease through 2025.

3. Monitoring Network

Pennsylvania currently operates one

PM 2.5 monitor in the Reading Area, which is located at the Reading Airport. The Reading Area maintenance plan includes a commitment by PADEP to continue to operate its EPA-approved monitoring network, as necessary to demonstrate ongoing compliance with the NAAQS. In its November 25, 2013 maintenance plan submittal, PADEP states that it will consult with EPA prior to making any necessary changes to the network and will continue to quality assure the monitoring data in accordance with the requirements of 40 CFR part 58.

4. Verification of Continued Attainment

To provide for tracking of the emission levels in the Area, PADEP requires major point sources to submit air emissions information annually and prepares a new periodic inventory for


### 76266 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

all PM 2.5 precursors every three years in
accordance with EPA’s Air Emissions Reporting Requirements (AERR). Emissions information will be compared to the attainment year inventory (2007)
to assure continued attainment with the
1997 annual PM 2.5 NAAQS and will be used to assess emissions trends, as necessary. Also, as noted in the previous subsection, PADEP will continue to operate its monitoring system in accordance with 40 CFR part58 and remains obligated to qualityassure monitoring data and enter all data into the AQS in accordance with federal requirements. PADEP will use this data, supplemented with additional data, as necessary, to assure continuing
attainment of the 1997 annual PM 2.5 NAAQS in the Area.

5. Contingency Measures

The contingency plan provisions for maintenance plans are designed to promptly correct a violation of the NAAQS that occurs after redesignation. Section 175A of the CAA requires that a maintenance plan include such contingency measures as EPA deems necessary to ensure that a state will promptly correct a violation of the NAAQS that occurs after redesignation. The maintenance plan should identify the events that would ‘‘trigger’’ the adoption and implementation of a contingency measure(s), the contingency measure(s) that would be adopted and implemented, and the schedule indicating the time frame by which the state would adopt and implement the measure(s).

The Reading maintenance plan includes a commitment by Pennsylvania to adopt and expeditiously implement necessary corrective actions in the event of a violation of the NAAQS, or in the event of certain triggers. The maintenance plan describes the procedures and schedule for the adoption and implementation of contingency measures to reduce
emissions should an exceedance or a violation occur, and consists of a first level response and a second level

response.

A first level response is triggered
when the annual mean PM 2.5 concentration exceeds 15.5 mg/m 3 in a single calendar year within the Reading Area, or if the periodic emissions inventory for the Reading Area exceeds the attainment year inventory by more than ten percent. The first level response will consist of a study to
determine if the emissions trends show increasing concentrations of PM 2.5 , and whether this trend is likely to continue. If it is determined through the study that action is necessary to reverse a trend of emissions increases, Pennsylvania will, as expeditiously as possible, implement necessary and appropriate control measures to reverse
the trend.

A second level response will be prompted if the two-year average of the
annual mean concentration exceeds 15.0

mg/m 3 within the Area. This would trigger an evaluation of the conditions causing the exceedance, whether
additional emission control measures should be implemented to prevent a violation of the standard, and analysis of potential measures that could be implemented to prevent a violation. Pennsylvania would then begin its adoption process to implement the measures as expeditiously as practicable.

Pennsylvania’s candidate contingency measures include the following: (1) A regulation based on the Ozone Transport Commission (OTC) Model Rule to update requirements for consumer products; (2) a regulation based on the Control Techniques Guidelines (CTG) for industrial cleaning solvents; (3) voluntary diesel projects such as diesel retrofit for public or private local onroad or offroad fleets, idling reduction technology for Class 2 yard locomotives, and idling reduction technologies or strategies for truckstops, warehouses, and other freighthandling facilities; (4) promotion of accelerated turnover of lawn and garden equipment, focusing on commercial equipment; and, (5) promotion of alternative fuels for fleets, home heating and agricultural use. The Commonwealth’s rulemaking process and schedule for adoption and implementation of any necessary contingency measure is shown in the plan as being 18 months from PADEP’s receipt of approval to initiate rulemaking.

For all of the reasons discussed in this section, EPA is proposing to approve Pennsylvania’s 1997 annual PM 2.5 maintenance plan for the Reading Area as meeting the requirements of section
175A of the CAA.

C. Transportation Conformity

Section 176(c) of the CAA requires
Federal actions in nonattainment and
maintenance areas to ‘‘conform to’’ the goals of SIPs. This means that such
actions will not cause or contribute to violations of a NAAQS, worsen the severity of an existing violation, or delay timely attainment of any NAAQS or any interim milestone. Actions involving Federal Highway Administration (FHWA) or Federal Transit Administration (FTA) funding or approval are subject to the transportation conformity rule (40 CFR part 93, subpart A). Under this rule, metropolitan planning organizations (MPOs) in nonattainment and
maintenance areas coordinate with state air quality and transportation agencies, EPA, and the FHWA and FTA to demonstrate that their long range transportation plans and transportation improvement programs (TIP) conform to applicable SIPs. This is typically determined by showing that estimated emissions from existing and planned highway and transit systems are less than or equal to the MVEBs contained
in the SIP.

On November 25, 2013, Pennsylvania
submitted a SIP revision that contains
the 2017 and 2025 PM 2.5 and NO X onroad mobile source budgets for the Reading Area comprised of Berks County, Pennsylvania. Pennsylvania did not provide emission budgets for SO 2 , VOC, and NH 3 because it concluded, consistent with the presumptions regarding these precursors in the Transportation Conformity Rule at 40 CFR 93.102(b)(2)(v), which predated and was not disturbed by the litigation
on the 1997 PM 2.5 Implementation Rule, that emissions of these precursors from motor vehicles are not significant
contributors to the Area’s PM 2.5 air quality problem. EPA issued conformity regulations to implement the 1997
annual PM 2.5 NAAQS in July 2004 and May 2005 (69 FR 40004, July 1, 2004 and 70 FR 24280, May 6, 2005). Those actions were not part of the final 1997

PM 2.5 Implementation Rule remanded to EPA by the D.C. Circuit Court in NRDC

v. EPA, No. 08–1250 (January 4, 2013),
because the Court concluded that EPA must implement that NAAQS pursuant to the PM-specific implementation provisions of subpart 4, rather than solely under the general provisions of subpart 1. That decision does not affect EPA’s proposed approval of the MVEBs for the Reading Area. The MVEBs are presented in Table 5.

EPA’s substantive criteria for determining adequacy of MVEBs are set out in 40 CFR 93.118(e)(4). Additionally, to approve the MVEBs, EPA must complete a thorough review of the SIP, in this case the PM 2.5 maintenance plan, and conclude that with the projected level of motor vehicle


### 76267 Federal Register / Vol. 79, No. 245 / Monday, December 22, 2014 / Proposed Rules

and all other emissions, the SIP will achieve its overall purpose, in this case providing for maintenance of the 1997
annual PM 2.5 NAAQS. EPA’s process for determining adequacy of a MVEB consists of three basic steps: (1) Providing public notification of a SIP submission; (2) providing the public the opportunity to comment on the MVEB during a public comment period; and, (3) EPA taking action on the MVEB.

EPA has reviewed the MVEBs and
found them consistent with the maintenance plan and that the budgets meet the criteria for adequacy and approval. Therefore, EPA is proposing to approve as well as find adequate the
2017 and 2025 PM 2.5 and NO X MVEBs for Berks County for transportation conformity purposes. Additional information pertaining to the review of
the MVEBs can be found in the TSD dated April 29, 2014, available on line

at www.regulations.gov, Docket ID No. EPA–R03–OAR–2014–0147. Any comments relating to EPA’s proposal to approve as well as find adequate the
2017 and 2025 PM 2.5 and NO X MVEBs for Berks County for transportation conformity purposes, as submitted by Pennsylvania, should be submitted in response to this notice of proposed rulemaking.

VI. Proposed Actions

EPA is proposing to approve the request submitted by Pennsylvania to redesignate the Reading Area from
nonattainment to attainment for the
1997 annual PM 2.5 NAAQS. EPA has
evaluated the Commonwealth’s redesignation request and determined that it meets the redesignation criteria set forth in section 107(d)(3)(E) of the CAA. The monitoring data demonstrates that the Reading Area has attained the
1997 annual PM 2.5 NAAQS, and, for the reasons discussed previously, that it will continue to attain the NAAQS. EPA is also proposing to approve the maintenance plan for the Reading Area as a revision to the Pennsylvania SIP because it meets the requirements of
section 175A of the CAA as described previously in this proposed rulemaking notice. In addition, EPA is proposing to approve the 2007 base year emissions inventory as meeting the requirements of section 172(a)(3) of the CAA. Furthermore, EPA is proposing to approve as well as find adequate the
2017 and 2025 PM 2.5 and NO X MVEBs submitted by Pennsylvania for Berks County for transportation purposes. Final approval of the redesignation request would change the designation of Reading Area from nonattainment to
attainment for the 1997 PM 2.5 annual NAAQS. EPA is soliciting public comments on the issues discussed in
this document. These comments will be considered before taking final action.

VII. 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 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 rule proposing to approve Pennsylvania’s redesignation request, maintenance plan, 2007 base year emissions inventory, and MVEBs for transportation conformity purposes for the Reading Area for the 1997 annual PM 2.5 NAAQS, 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.
