The Fourth Amendment to the Consent Decree revises the CD in four ways. First, it transfers uncompleted and ongoing responsibilities for the Philadelphia Refinery from Sunoco to PES R&M LLC. Secondly, it extends the time to achieve final SO2 and NOx emission limits at Philadelphia's 868 FCCU from 2014 to 2016, while establishing an interim SO2 emissions limit. Next, it allows for the use of emissions reductions achieved by reaching the final SO2 and NOx limits on the 868 FCCU or achieved from the permanent shut down of the Marcus Hook Refinery (to the extent the Philadelphia and Marcus Hook Refineries are determined to be a single source) as credits or offsets in any PSD, major non-attainment and or minor NSR permit at the Philadelphia Refinery, provided that the new or modified units meet BACT. Finally, it requires the installation, operation, and maintenance of fence line monitoring of refinery pollutants.
REGION 3 IS THE LEAD REGION FOR THIS NATIONAL CASE.
