Sunoco Refining & Marketing has agreed to pay $130,000 in civil penalties for air-quality violations at its refinery in Marcus Hook, Delaware County.
In incidents related to a string of equipment failures - boiler malfunctions, compressor and instrument failures, a cooling-system leak, and flare-light problems - the facility emitted pollutants beyond its permit limits.
The incidents occurred between January and September 2009. The substances emitted included carbon monoxide, sulfur dioxide, nitrogen oxide, particulate matter, volatile organic compounds, butane, and propane. Joseph A. Feola, southeast regional director of the Pennsylvania Department of Environmental Protection, said Sunoco had corrected the equipment failures.
