Approval of Proposed Interpollutant Trading Request; Pennsylvania; Control of Fine Particulate Matter: Notice of Availability
AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Notice of Availability.
SUMMARY:
This action announces the availability of EPA's approval of a request submitted by the Commonwealth of Pennsylvania to approve the use of sulfur dioxide (SO 2 ) emission reduction credits to offset increased emissions of fine particulate matter (PM 2.5 ) in the York County PM 2.5 nonattainment area. EPA is approving this request in accordance with the Clean Air Act (CAA).

II. Background
Under section 173 of the CAA, all major sources and major modifications at existing major sources within a nonattainment area must obtain emissions reductions to offset any emissions increases resulting from the project in an amount that is at least equal to the emissions increase, and that is consistent with reasonable further progress toward attainment. A final rule published on May 16, 2008, in the Federal Register entitled "Implementation of the New Source Review (NSR) Program for PM 2.5 " (72 FR 28349) established, among other things, the offset ratios, i.e. , the amount of emissions reductions required to offset the emissions increase, for direct emissions of PM 2.5 as well as its precursors. The rule also allows limited interpollutant (precursor) trading for the purpose of PM 2.5 offsets based on pollutant-specific trading ratios if such offsets are established as part of the State Implementation Plan (SIP) or if they comply with an interprecursor trading hierarchy and ratio approved by the Administrator. EPA previously conducted a technical assessment to develop preferred interpollutant trading ratios to be used for the purposes of PM 2.5 offsets. The preferred ratios were published in the preamble to the May 16, 2008 rule and set a 40:1 ratio of SO 2 reductions to offset PM 2.5 emission increases. The modeling used to derive the preferred ratio is described in a technical memo to the docket for the May 16, 2008 final rule and is included in the docket for this action.
States, such as Pennsylvania, that will need to update their State Implementation Plans (SIPs) to implement NSR for PM 2.5 in nonattainment areas, must implement a transitional NSR permitting program for PM 2.5 pursuant to appendix S to 40 CFR part 51. Appendix S at Section IV.G.5 allows the offset requirements for direct PM 2.5 emissions to be satisfied by reductions of SO 2 , a PM 2.5 precursor, if such offsets are approved by the Administrator.
On January 20, 2009, the Pennsylvania Department of Environmental Protection (PADEP) submitted a request to EPA to allow interpollutant trading for offsets required for the construction and operation of the Conectiv Mid-Merit LLC's proposed natural gas-fired plant in Peach Bottom Township, Pennsylvania. This request was submitted pursuant to Pennsylvania's transitional NSR program under Appendix S for NSR permitting in PM 2.5 nonattainment areas. The Commonwealth specifically requested approval to use EPA's preferred trading ratio of 40 tons of SO 2 reductions to offset every ton of PM 2.5 emission increases. The new facility is to be located in the York County nonattainment area for PM 2.5 .
On February 23, 2009, EPA published in The York Dispatch and York Daily Record a notice of intent to approve PADEP's Proposed Interpollutant Trading Request for York County, Pennsylvania. The notices of intent to approve announced EPA's pending approval of the PADEP's request to allow the use of SO 2 emission reduction credits to offset increased emissions of PM 2.5 , at a ratio of 40 tons SO 2 to one ton of PM 2.5 emissions, in the York County PM 2.5 nonattainment area. In these notices, EPA announced that comments would be received for 30 days. No comments were received in response to the notice. EPA approved PADEP's request to allow precursor trading for the purpose of PM 2.5 offsets on April 14, 2009.
III. Judicial Review
Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by July 20, 2009. Filing a petition for reconsideration by the Administrator of this approval does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such action. This action may not be challenged later in proceedings to enforce its requirements. ( See section 307(b)(2).)
