City of Quincy Agrees to Remedy Discharges of Stormwater Containing Sewage

BOSTON – The U.S. Attorney’s Office has entered into a consent decree with the City of Quincy to resolve violations of the Clean Water Act regarding the City’s stormwater and sanitary sewer systems. Water sampling indicated untreated sanitary sewage discharging from numerous Quincy stormwater outfalls, including outfalls discharging at beach areas.

The settlement requires Quincy to implement extensive remedial measures to minimize the discharge of sewage and other pollutants into Quincy Bay, Dorchester Bay, Neponset River, Hingham Bay, Boston Harbor and other water bodies in and around Quincy. The cost of the remedial measures is expected to be in excess of $100 million. The City will also pay a civil penalty of $115,000.

Under the proposed consent decree, Quincy will implement a comprehensive and integrated program to investigate, repair and rehabilitate its stormwater and sanitary sewer systems. The proposed settlement is also consistent with U.S. Environmental Protection Agency (EPA) directives to strengthen enforcement of violations of cornerstone environmental statutes in communities disproportionately impacted by pollution, with special focus on achieving remedies with tangible benefits for the community.

“This settlement is a reminder that municipalities must comply with the law and environmental standards to prevent and address pollution caused by defects in their stormwater and sewage systems,” said Acting United States Attorney Nathaniel R. Mendell. “This is a matter of environmental protection and public health.”

“This settlement builds on work done over the past three decades to address pollution in Boston Harbor,” said EPA New England Acting Regional Administrator Deborah Szaro. “The work required under the proposed settlement will achieve cleaner and healthier water in Quincy and nearby areas. This will protect people’s health, making it safer to enjoy beaches or other recreation in or on the bays and rivers in the area.”

In March 2019, the U.S. Attorney’s Office filed a civil complaint alleging that the City of Quincy inadequately controlled sewage leaking from its sanitary sewer system, allowing sewage to mix with stormwater and be discharged from the municipal storm sewer system into nearby waterbodies, including at beach locations. The complaint also alleged that Quincy’s sanitary sewer system has overflowed on numerous occasions, resulting in discharges of sewage.

Raw sewage overflows from sanitary sewers and discharges of stormwater mixed with sewage from municipal storm sewer systems introduce a variety of harmful pollutants, including disease causing organisms, and can contribute to illnesses and beach and shellfish bed closings.

The proposed consent decree establishes a schedule for Quincy to investigate the sources of sewage being discharged from its storm drains. Quincy will first complete its investigations of drainage areas discharging to beach areas, including Wollaston Beach and the Adams Shore area. Quincy will prioritize the rest of the investigations according to the sensitivity of receiving waters and evidence of sewage. The proposed consent decree also requires Quincy to remove all identified sources of sewage as expeditiously as possible. In addition, Quincy is required to conduct frequent and enhanced monitoring (in both dry and wet weather) of its stormwater outfalls. Until pollutants are removed from its storm drain discharges, Quincy will be required to post notices to warn beachgoers of contaminated stormwater at such storm drain outfalls. The remedies under the proposed consent decree also include the investigation and repair of Quincy’s sanitary sewer infrastructure, and the integration of that work with its stormwater investigations.

Some portions of Quincy’s sanitary sewer system are over 100 years old. Numerous studies conducted by Quincy have identified significant and widespread defects in the sanitary sewer system, including cracks that allowed sewage to leak. While Quincy has made some repairs to the sanitary sewer system, the proposed consent decree will require future work to be conducted on a fixed schedule and coordinated with its stormwater investigations. The proposed consent decree requires the City to conduct all investigations and complete remedial work by December 2034.

Acting U.S. Attorney Mendell and EPA Acting Regional Administrator Szaro made the announcement today. The matter was handled by Susan Poswistilo of Mendell’s Civil Division and Senior Counsel David Gordon and Donald Frankel of the Justice Department’s Environment and Natural Resources Division.
