2013-17020. Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Infrastructure Requirements for the 2008 Lead National Ambient Air Quality Standards

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania pursuant to the Clean Air Act (CAA). Whenever new or revised national ambient air quality standards (NAAQS) are promulgated, the CAA requires states to submit a plan for the implementation, maintenance, and enforcement of such NAAQS. The plan is required to address basic program elements including, but not limited to regulatory structure, monitoring, modeling, legal authority, and adequate resources necessary to assure attainment and maintenance of the standards. These elements are referred to as infrastructure requirements. The Commonwealth of Pennsylvania made a submittal addressing the infrastructure requirements for the 2008 lead NAAQS. This action proposes approval of portions of the submittal. This action is being taken under the CAA.

SUPPLEMENTARY INFORMATION:

On September 24, 2012, the Pennsylvania Department of Environmental Protection (PADEP) submitted a revision to its SIP to satisfy the requirements of section 110(a)(2) of the CAA for the 2008 lead NAAQS.

I. Background

On October 15, 2008, EPA substantially strengthened the primary and secondary lead NAAQS (hereafter the “2008 lead NAAQS”), revising the level of the primary (health-based) standard from 1.5 micrograms per cubic meter (μg/m³) to 0.15 μg/m³, measured as total suspended particles (TSP) and not to be exceeded with an averaging time of a rolling 3-month period. EPA also revised the secondary (welfare-based) standard to be identical to the primary standard, as well as the associated ambient air monitoring requirements. See 40 CFR 50.16.

Section 110(a) of the CAA requires states to submit SIPs to provide for the implementation, maintenance, and enforcement of a new or revised NAAQS within three years following the promulgation of such NAAQS or within such shorter period as EPA may prescribe. The contents of that submission may vary depending upon the facts and circumstances. In particular, the data and analytical tools available at the time the state develops and submits the SIP for a new or revised NAAQS affect the content of the submission. The contents of such SIP submissions may also vary depending upon what provisions the state's existing SIP already contains.

Pursuant to section 110(a)(1) of the CAA, states are required to submit SIPs meeting the applicable requirements of section 110(a)(2) within three years after promulgation of a new or revised NAAQS or within such shorter period as EPA may prescribe. Section 110(a)(1) provides the procedural and timing requirements for SIPs and section 110(a)(2) requires states to address basic SIP elements such as requirements for monitoring, basic program requirements and legal authority that are designed to assure attainment and maintenance of the NAAQS. More specifically, section 110(a)(2) lists specific elements that states must meet for “infrastructure” SIP requirements related to a newly established or revised NAAQS.

For the 2008 lead NAAQS, states typically have met many of the basic program elements required in CAA section 110(a)(2) through earlier SIP submissions in connection with previous lead NAAQS. Nevertheless, pursuant to CAA section 110(a)(1), states have to review and revise, as appropriate, their existing lead NAAQS SIPs to ensure that the SIPs are adequate to address the 2008 lead NAAQS. To assist states in meeting this statutory requirement, EPA issued a guidance on October 14, 2011, entitled, “Guidance on Infrastructure State Implementation Plan (SIP) Elements Required Under sections 110(a)(1) and 110(a)(2) for the 2008 Lead (Pb) National Ambient Air Quality Standards (NAAQS)” (hereafter the “2011 Lead Infrastructure Guidance”), which lists the basic elements that states should include in their SIPs for the 2008 lead NAAQS.

II. Summary of SIP Revision

On September 24, 2012, PADEP provided a submittal to satisfy the requirements of section 110(a)(2) of the CAA for the 2008 lead NAAQS. This submittal addresses the following infrastructure elements, which EPA is proposing to approve: CAA section 110(a)(2)(A), (B), (C), (D)(i)(I), (D)(i)(II), (D)(ii), (E)(i), (E)(iii), (F), (G), (H), (J), (K), (L), and (M), or portions thereof. EPA is taking separate action on the portion of (E)(ii) as it relates to CAA section 128 (State Boards). Pennsylvania did not submit element (I) which pertains to the nonattainment requirements of part D, Title I of the CAA, since this element is not required to be submitted by the 3-year submission deadline of CAA section 110(a)(1), and will be addressed in a separate process.

In accordance with the decision of the U.S. Court of Appeals for the DC Circuit, the EPA at this time is not treating the 110(a)(2)(D)(i)(I) SIP submission from the Commonwealth of Pennsylvania as a required SIP submission. See EME Homer City Generation, LP v. EPA, 696 F.3d 7 (DC Cir. 2012), reh'g denied 2013 U.S. App. LEXIS 1623 (Jan. 24. 2013). However, even if the submission is not considered to be “required,” the EPA must act on the 110(a)(2)(D)(i)(I) SIP submission from Pennsylvania because section 110(k)(2) of the CAA requires the EPA to act on all SIP submissions. Unless the EME Homer City decision is reversed or otherwise modified by the Supreme Court, states are not required to submit 110(a)(2)(D)(i)(I) SIPs until the EPA has quantified their obligations under that section. In this action, EPA is proposing to act on the Commonwealth of Pennsylvania's 110(a)(2)(D)(i)(I) submission.

III. Proposed Action

EPA is proposing to approve the following section 110(a)(2) elements of Pennsylvania's SIP revision: (A), (B), (C), (D)(i)(I), (D)(i)(II), (D)(ii), (E)(i), (E)(iii), (F), (G), (H), (J), (K), (L), and (M), or portions thereof. EPA will take separate action on section 110(a)(2)(E)(ii). Pennsylvania's SIP revision provides the basic program elements specified in CAA section 110(a)(2) necessary to implement, maintain, and enforce the 2008 lead NAAQS. This SIP revision was submitted on September 24, 2012. This action does not include section 110(a)(2)(I) of the CAA which pertains to the nonattainment requirements of part D, Title I of the CAA, since this element is not required to be submitted by the 3-year submission deadline of CAA section 110(a)(1), and will be addressed in a separate process. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

IV. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:

• Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
• does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
• is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
• does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
• does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
• is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
• is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
• is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
• does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this proposed rule, which satisfies certain infrastructure requirements of section 110(a)(2) of the CAA for the 2008 lead NAAQS for the Commonwealth of Pennsylvania, 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.
