2012-24380. Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; The 2002 Base Year Inventory for the Pittsburgh-Beaver Valley Area for 1997 Fine Particulate Matter National Ambient Air Quality Standard

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve the fine particulate matter (PM_2.5) 2002 base year emissions inventory portion of the Pennsylvania State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania, through the Pennsylvania Department of Environmental Protection (PADEP), on November 10, 2009 for the Pittsburgh-Beaver Valley, PA nonattainment area (hereafter referred to as the Area). The emissions inventory is part of the November 10, 2009 SIP revision that was submitted to meet nonattainment requirements related to the Area for the 1997 PM_2.5 National Ambient Air Quality Standard (NAAQS) SIP.

I. Background

Throughout this document, whenever “we,” “us,” or “our” is used, we mean EPA. On July 18, 1997 (62 FR 38652), EPA promulgated the 1997 PM_2.5 NAAQS, including an annual standard of 15.0 micrograms per cubic meter (μg/m³) based on a 3-year average of annual mean PM_2.5 concentrations, and a 24-hour (or daily) standard of 65 μg/m³ based on a 3-year average of the 98th percentile of 24-hour concentrations. EPA established the standards based on significant evidence and numerous health studies demonstrating that serious health effects are associated with exposures to PM_2.5.

Following promulgation of a new or revised NAAQS, EPA is required by the CAA to designate areas throughout the United States as attaining or not attaining the NAAQS; this designation process is described in section 107(d)(1) of the CAA. In 1999, EPA and state air quality agencies initiated the monitoring process for the 1997 PM_2.5 NAAQS and, by January 2001, established a complete set of air quality monitors. On January 5, 2005, EPA promulgated initial air quality designations for the 1997 PM_2.5 NAAQS (70 FR 944), which became effective on April 5, 2005, based on air quality monitoring data for calendar years 2001-03.

On April 14, 2005, EPA promulgated a supplemental rule (70 FR 19844) amending our initial designations (70 FR 944), with the same effective date (April 5, 2005). As a result of this supplemental rule, PM_2.5 nonattainment designations are in effect for 39 areas, comprising 208 counties within 20 states (and the District of Columbia) nationwide, with a combined population of approximately 88 million. The Area, which is the subject of this rulemaking, was included in the list of areas not attaining the 1997 PM_2.5 NAAQS. The Area consists of the following: Allegheny County (remainder of county not included in Liberty-Clairton nonattainment area); Armstrong County (portion consisting of Elderton Borough and Plum Creek and Washington Townships); Beaver County; Butler County; Greene County (portion consisting of Monongahela Township); Lawrence County (portion consisting of Township of Taylor south of New Castle City); Washington County; and Westmorland County.

Section 172(c)(3) of the CAA requires submission and approval of a comprehensive, accurate, and current inventory of actual emissions. This proposed approval is limited to the emissions inventory for the Area. Separate action will be taken on the remainder of Pennsylvania's November 10, 2009 SIP submittal.

II. Summary of SIP Revision

The 2002 base year emission inventory submitted by PADEP on November 10, 2009 for the Area includes emissions estimates that cover the general source categories of point sources, area sources, on-road mobile sources, and non-road mobile sources. The pollutants that comprise the inventory are PM_2.5, coarse particles (PM₁₀), nitrogen oxides (NO_X), volatile organic compounds (VOCs), ammonia (NH₃), and sulfur dioxide (SO₂). EPA has reviewed the results, procedures and methodologies for the base year emissions inventory submitted by PADEP. The year 2002 was selected by PADEP as the base year for the emissions inventory per 40 CFR 51.1008(b). A discussion of the emissions inventory development as well as the emissions inventory for the Area can be found in Section III of the November 10, 2009 SIP submittal.

Table 1, below, provides a summary of the annual 2002 emissions of PM_2.5, PM₁₀, SO₂, NO_X, VOCs, and NH₃ for the Area submittal.

Table 1—2002 Annual Emissions

[Tons per year]

Pittsburgh-Beaver Valley Area 2002	PM2.5	PM10	SO2	NOX	VOC	NH3
Stationary Point Sources	4868	11149	463501	110618	5157	462
Area Sources	7916	41206	9905	8622	36683	2948
Highway Vehicle Sources	824	1164	1770	53268	25638	1884

Totals	14904	54879	476871	198483	80898	5303

The CAA section 172(c)(3) emissions inventory is developed by the incorporation of data from multiple sources. States were required to develop and submit to EPA a triennial emissions inventory according to the Consolidated Emissions Reporting Rule (CERR) for all source categories (i.e., point, area, nonroad mobile and on-road mobile). The review and evaluation of the methods used for the emissions inventory submitted by Pennsylvania are found in the Technical Support Document dated August 12, 2010 available online at www.regulations.gov,, Docket No. EPA-R03-OAR-2010-0601. EPA finds that the process used to develop this emissions inventory for the Area is adequate to meet the requirements of CAA section 172(c)(3), the implementing regulations, and EPA guidance for emission inventories.

III. Proposed Action

EPA is proposing to approve the 2002 base year emissions inventory portion of the SIP revision submitted by the Commonwealth of Pennsylvania on November 10, 2009 for the Pittsburgh-Beaver Valley Area. We have made the determination that this action is consistent with section 110 of the CAA. 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, pertaining to the PM_2.5 2002 base year emissions inventory portion of the Pennsylvania SIP for the Pittsburgh-Beaver Valley Area, 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.
