The lawsuit was filed on Friday in Baltimore City Circuit Court on behalf of the Maryland Department of the Environment. It concerns unpermitted discharges from the city-owned Back River Wastewater Treatment Plant and Patapsco Wastewater Treatment Plant, the two largest such plants in the state.

According to the complaint, “extensive violations of MDE-issued discharge permits” were found during multiple inspections of the plants in 2021, including: an excess of pollutants discharged from the plants, a failure to report sampling results, a failure to comply with stormwater discharge requirements, and a failure to provide various required reports, among other issues.
