The New Hampshire Department of Environmental Services (DES) received funds in 2001 from the New Hampshire Estuaries Project (NHEP) to train municipal staff in coastal communities to identify illicit discharges. This final report describes the resulting training workshops that were held in January, 2003. NHEP chose to fund this activity for a number of reasons. Primarily, it helped to fulfill one of the water quality action plans identified in the NHEP Management Plan. In addition, many coastal municipalities are now regulated under Phase II of the federal stormwater regulations. Regulated municipalites must develop best management practices to detect and eliminate illicit discharges into the municipal storm sewer system.
