1200 Series Construction Stormwater Permits - General Use

Stormwater runoff from land and impervious areas such as paved streets, parking lots, and building rooftops during rainfall and snow events often contain pollutants that could adversely affect water quality. National Pollutant Discharge Elimination System permits are required for stormwater discharges to surface waters from construction and industrial activities and municipalities if stormwater from rain or snow melt leaves your site through a "point source" and reaches surface waters either directly or through storm drainage.  A point source is a natural or human-made conveyance of water through such things as pipes, culverts, ditches, catch basins, or any other type of channel.

Permit reissuance

DEQ has begun work on the renewal of the current 1200-C Construction Stormwater General Permit which is set to expire on Dec. 14, 2025. The permit reissuance process includes gathering early input from interested parties, a formal public comment period on the draft permit, and formal public meetings and hearings. Check back here or sign up for the Stormwater Newsletter for the latest developments.
