PROPOSED REVISION TO THE STATE
IMPLEMENTATION PLAN TO MEET THE REQUREMENTS OF REASONABLY AVAILABLE CONTROL TECHNOLOGY SET FORTH BY THE CLEAN AIR ACT UNDER THE 8-HOUR
OZONE NAAQS.
Public Hearing
The Clean Air Act Amendments of 1990 (CAA) requires Philadelphia County (Philadelphia) to submit to the U.S. Environmental Protection Agency (EPA) a State Implementation Plan (SIP) revision demonstrating that Philadelphia has implemented all necessary Reasonably Available Control Technology (RACT) controls on all major stationary sources of volatile organic compounds (VOC) and oxides of nitrogen (NOx).
The Philadelphia Department of Public Health, Air Management Services (AMS) is now seeking public comment on a proposed SIP revision that updates Philadelphia's RACT demonstration for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS).
On December 13, 2013 (78 FR 75902), EPA conditionally approved Philadelphia's 1997 8-hour ozone RACT demonstration provided in the 2006 and 2010 SIP revisions, based upon a commitment from AMS to submit additional SIP revisions to provide source-specific RACT determinations for certain major sources of VOC and NOx in Philadelphia and a certification that previously adopted source-specific RACT controls approved by EPA in the Pennsylvania's SIP under the 1-hour ozone NAAQS for the remaining sources in Philadelphia County (as listed in 40 CFR 52.2020(d)(1)) continue to adequately represent RACT for the 1997 8-hour ozone NAAQS.
This SIP revision is intended to partially satisfy AMS' commitment by addressing source-specific RACT determinations for the following major sources of NOx: Exelon - Delaware Station (1325 N. Beach Street, Philadelphia, PA 19125), with three 15.5 MW combustion turbines and one 17.5 MW combustion turbine; Exelon Generating Company - Richmond Station (3901 N. Delaware Avenue, Philadelphia, PA 19137), with two 66 MW combustion turbines; Exelon Generating Company - Schuylkill Station (2800 Christian Street, Philadelphia, PA 19146), with one 233 MMBTU/hr combustion turbine, one 284 MMBTU/hr combustion turbine, and one 2.75 MW emergency generator; Veolia Energy Philadelphia - Edison Station (908 Sansom Street, Philadelphia, PA 19107), with two 283 MMBTU/hr boilers and two 335 MMBTU/hr boilers; Veolia Energy - Schuylkill Station (2600 Christian Street, Philadelphia, PA 19146), with two 795 MMBTU/hr boilers, one 761 MMBTU/hr boiler, one 1119 MMBTU/hr boiler, and one 1515 MMBTU/hr combustion turbine.
In addition, AMS is revising the RACT plan approvals for the following facilities: Veolia Energy Philadelphia - Edison Station (908 Sansom Street, Philadelphia, PA 19107): AMS is adding emission limits of 185.93 tons of NOx per rolling 12 month period for the Boilers #1 and #2 and 220.1 tons of NOx per rolling 12 month period for Boilers #3 and #4; Veolia Energy - Schuylkill Station (2600 Christian Street, Philadelphia, PA 19146): AMS is adding an emission limit of 365.6 tons of NOx per rolling 12 month period for Boiler #23.
