HARRISBURG (AP) – A pipeline developer will dredge part of a contaminated lake and pay over $4 million for spilling thousands of gallons of drilling fluids at a popular state park, according to PA officials, who announced the settlement with Sunoco Pipeline LP. The spill happened in August 2020 during construction of Sunoco’s Mariner East pipeline. The spill contaminated wetlands, tributaries, and part of the 535-acre lake at Marsh Creek State Park in Chester County. About 33 acres of the lake were placed off limits to boating and fishing due to the spill. The settlement will allow construction on the pipeline to resume.
