Philadelphia — The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced a settlement with the Delaware County Regional Water Quality Control Authority (DELCORA) resolving alleged Clean Water Act violations involving combined sewer overflows (CSOs) to the Delaware River and its tributaries. In a proposed consent decree, DELCORA has agreed to develop and implement a plan to control and significantly reduce overflows from its sewer system, which will improve the water quality of the Delaware River, Chester Creek and Ridley Creek near Philadelphia, Pa.

Based on information submitted by DELCORA, EPA estimates that the Authority could spend as much as $200 million to implement an overflow control plan that complies with the terms of the Clean Water Act. Once the specific pollution control measures are selected and approved, the settlement requires DELCORA to implement the plan as quickly as possible, with a 20-year deadline from when the settlement is filed in court to complete the necessary controls. DELCORA must also pay a $1.375 million penalty for prior violations, which will be split between the United States and the Commonwealth of Pennsylvania, a co-plaintiff in this case.

“This settlement achieves a long term solution to reduce millions of gallons of sewage overflows into the creeks and the Delaware River,” said EPA Regional Administrator Shawn M. Garvin. “It puts DELCORA on a sustainable path to managing stormwater in ways that will benefit the health and quality of local communities and waters for years to come.”

The settlement stands to address longstanding problems with DELCORA’s combined sewer system, which when inundated with stormwater, discharges raw sewage, industrial waste, nitrogen, phosphorus, and polluted stormwater into Chester Creek, Ridley Creek, and the Delaware River. According to DELCORA, the volume of combined sewage that overflows from the system is approximately 739 million gallons annually.

DELCORA’s wastewater facilities serve approximately 500,000 people in the greater Philadelphia area, including many low-income communities. Once fully implemented, the settlement will help reduce the direct exposure of low-income and minority populations in the service area to raw sewage. DELCORA must also seek input from the public on the long-term control plan, including from Chester and surrounding communities that have historically been overburdened by pollution.

The consent decree also requires DELCORA to notify the public of CSO discharges using a visual notification system, including warning lights and flags at CSO outfalls, where a sewer empties into local waterways.

Keeping raw sewage and contaminated storm water out of the waters of the United States is one of EPA’s National Enforcement Initiatives. EPA is working to reduce discharges from sewer overflows by securing commitments from cities to implement timely, affordable solutions.

The proposed consent decree is subject to a 30-day public comment period and court approval after it is published in the Federal Register.
