Notice of Public Meeting and Solicitation of Public Comment - Draft Revised Total Maximum Daily Loads for Organics and Metals in the Anacostia River Watershed

Friday, July 9, 2021

The Director of the Department of Energy and Environment (the Department) is submitting for public review and comment the draft revised Total Maximum Daily Loads (TMDLs) for organics and metals in the Anacostia River watershed.

The revisions are a result of a challenge in federal District Court to the 2003 TMDLs for failing to include daily load expressions. On January 15, 2009, the Anacostia Riverkeeper, Friends of the Earth, and Potomac Riverkeeper filed a complaint (Case No.: 1:09-cv-00098-JDB) that certain District TMDLs did not include a daily load expression as required by Friends of the Earth vs. the Environmental Protection Agency, 446 F.3d 140, 144 (D.C. Cir. 2006). The District Court ultimately vacated the TMDLs, but delayed vacatur to allow the District and EPA sufficient time to establish and approve replacement TMDLs.  The vacatur remains through September 30, 2021.

The draft revised TMDLs were developed collaboratively with the US Environmental Protection Agency (EPA) and the Maryland Department of the Environment. The revisions provide daily organics and metals loading expressions that attain water quality criteria in the District’s water quality standards. The revised TMDLs will be subject to approval by the EPA. 

The draft revised TMDLs address organics and metals, specifically organochlorine pesticides (chlordane, dieldrin, heptachlor epoxide, dichlorodiphenyltrichloroethane (DDT) and its breakdown products), polycyclic aromatic hydrocarbons (PAHs), and metal (arsenic, copper, and zinc) impairments in the Anacostia River, its tributaries, and Kingman Lake. They are being proposed to replace the TMDLs for organics and metals in the Anacostia River, Fort Chaplin Tributary, Fort Davies Tributary, Fort Dupont Creek, Fort Stanton Tributary, Hickey Run, Nash Run, Popes Branch, Texas Avenue Tributary, and Watts Branch. They include heptachlor epoxide TMDLs to address listings of impaired water bodies in both Maryland and the District. These TMDLs were initially approved by EPA in 2003.
