Proposed Changes to the Regional Haze State Implementation Plan Revision; BART Limits for the Cheswick Power Plant, Allegheny County; Public Hearing

[43 Pa.B. 7506]
[Saturday, December 21, 2013]

 The Department of Environmental Protection (Department) is proposing changes to the approved Regional Haze State Implementation Plan (SIP) revision to modify and correct certain errors in the original submittal. The Commonwealth's Regional Haze SIP revision was submitted to the United States Environmental Protection Agency (EPA) on December 20, 2010. On July 13, 2012, the EPA granted ''limited approval'' of the SIP submittal. See 77 FR 41279 (July 13, 2012). The EPA also issued a ''limited disapproval'' of certain Regional Haze SIP revisions because states including this Commonwealth relied on the Clean Air Interstate Rule to satisfy certain requirements in 77 FR 33642 (June 7, 2012).

 In this proposed SIP revision, the Department refers to the approved Regional Haze SIP revision as the December 20, 2010, Regional Haze SIP. This proposed SIP revision is submitted in accordance with the visibility and regional haze provisions of sections 169A and 169B of the Federal Clean Air Act (act) (42 U.S.C.A. §§ 7491 and 7492) and the Federal regional haze rule codified in 40 CFR 51.308 (relating to regional haze program requirements).

 This proposed SIP revision will make changes to information relating to Boiler No. 1 of the Orion Power (now GenOn Power Midwest, LP) Cheswick Generating Station (the Cheswick Plant) in Allegheny County, relating to BART control levels. These changes include updating the facility owner's name, updating the permit numbers and dates of issuance for the boiler, correcting the emission limit for particulate matter less than 10 micrometers (PM10) for the boiler and deleting the emission limits for sulfer dioxide and nitrogen oxide that were mistakenly included in the December 20, 2010, Regional Haze SIP revision. This proposed SIP revision will also replace the BART review memorandum completed by the Allegheny County Health Department for the Cheswick Plant with a new review memo dated November 7, 2012. None of the proposed corrections or updates will interfere with any applicable act requirement, including the Commonwealth's reasonable progress to achieving natural visibility conditions as required by the act.

 The Department is seeking public comment on this proposed SIP revision. The proposed Regional Haze SIP revision is available on the Department's web site at (choose keyword: ''Clean air plans'') or through the contact persons listed as follows.

 The Department will hold three public hearings on this proposed SIP revision according to the following schedule:
