The State of Maryland's Department of the Environment (MDE), Sediment, Stormwater, and Dam Safety Program (SSDSP) is responsible for administering Maryland's erosion and sediment control, stormwater management, and dam safety programs. The two stormwater management programs began in 1970 and 1982, respectively, and form the fundamental backbone of all new development water quality control efforts in the State. Both are mandated by statute, address both the temporary and the permanent impacts associated with development activities, and implemented statewide. MDE’s Dam Safety Program ensures all dams in Maryland are designed, constructed, operated and maintained safely to prevent dam failures and the consequences of failure.
