The U.S. Environmental Protection Agency (EPA), the Department of Justice, and the Mississippi Department of Environmental Quality (MDEQ) have reached a comprehensive Clean Water Act settlement with the city of Jackson, Miss.

Jackson has agreed to make improvements to its sewer systems to eliminate unauthorized overflows of untreated raw sewage and unauthorized bypasses of treatment at the Savanna Street Wastewater Treatment Plant (WWTP), the city’s largest wastewater treatment facility.

“This agreement will bring lasting benefits to the people of Jackson by reducing the threats to public health posed by untreated sewage overflows,” said Ignacia S. Moreno, assistant attorney general for the Justice Department’s Environment and Natural Resources Division, in a prepared statement. “The settlement will bring the city into compliance with the nation’s Clean Water Act, requiring significant upgrades to the existing sewer system. Under the settlement, assistance will be provided to residents to repair sewer connections in lower-income areas that have suffered historically from overflows of untreated sewage.”

The consent decree requires Jackson to implement specific programs designed to ensure proper management, operation and maintenance of its sewer systems. In order to address the problem of wet weather overflows of raw sewage from the sewer lines, Jackson will develop and implement a comprehensive sewer system assessment and rehabilitation program. The city will also develop and implement a comprehensive performance evaluation and composite correction program to reduce the bypasses of treatment at the Savanna Street WWTP.

The consent decree also requires Jackson to develop and implement numerous sewer system capacity, management, operations and maintenance programs, including a pump station operation and preventive maintenance program, a WWTP operation and maintenance program, and a water quality monitoring program.

In addition to the control requirements, the consent decree requires Jackson to pay a civil penalty of $437,916. As part of the settlement, Jackson has also agreed to implement a supplemental environmental project valued at $875,000 that is intended to provide additional environmental benefits to the local community. The project involves reducing the flow of water from entering the sewer system by eliminating illicit stormwater connections and repairing defective private lateral sewer lines from the low-income residential properties.
