Stormwater & Water Quality

Stormwater is runoff generated from rain and snowmelt that, as it flows over land and impervious surfaces, collects debris, sediment, chemicals, and other pollutants that can adversely affect water quality when discharged untreated. Many stormwater discharges associated with DOT&PF construction or maintenance activities require an Alaska Pollutant Discharge Elimination System (APDES) permit. In Alaska, the Department of Environmental Conservation (DEC) serves as the authority for stormwater permitting. This page contains information and resources to assist in regulatory compliance.
