Stormwater Pollution Prevention Plan Preparation

Location: Washington, DC

Client: DC Water and Sewer Authority

CCJM was retained by the DC Water and Sewer Authority to provide engineering services under DCFA #395-WSA to identify all facilities owned and operated by the DC Water with the exception of the Blue Plains Advanced Wastewater Treatment Plant (AWWTP) and to prepare Stormwater Pollution Prevention Plans (SWPPPs) for the facilities that require one.

Stormwater runoff originating from precipitation may pick up pollutants from areas where industrial activities occur and discharge them to nearby water bodies. Under the Clean Water Act (CWA), dischargers to “Waters of the United States” require a National Pollutant Discharge Elimination System (NPDES) permit. The NPDES Municipal Separate Storm Water System permit no. DC0000221 authorized the District of Columbia to discharge from all portions of the Municipal Separate Storm Sewer System (MS4) owned and operated by the District to the receiving waters: Potomac River, Anacostia River and their tributaries. To assure compliance with the permit, all participating agencies in the District are required to prepare and implement SWPPPs. The purpose of the SWPPP is to identify possible pollutant sources of stormwater at DC Water facilities, and to identify Best Management Practices that, when implemented, will reduce or eliminate pollutant loading to the receiving waters.

A total of 39 facilities that are owned and operated by DC Water including water and wastewater pumping stations, and water reservoirs are covered under this centralized SWPPP. CCJM delivered its report for approval in December 2010.
