Mission

The Colorado Stormwater Council (CSC) is an organization for local governments who own a storm drainage system and are required to have a municipal permit (National Pollutant Discharge Elimination System (NPDES) for the discharge from those systems to state waters. In the State of Colorado, the Colorado Department of Public Health and the Environment (CDPHE) is responsible for regulating the discharge of stormwater by issuing discharge permits through the Colorado Discharge Permit System.
