1200 Series Construction Stormwater Permits - General Use

Update

DEQ is rescheduling the construction stormwater general permit listening sessions. Check back here or sign up for GovDelivery to be notified of the new dates for these sessions.

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.

1200-C renewal 2025

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.

DEQ will host three listening sessions to begin to engage interested parties on permit renewal efforts. Sessions will include a summary of proposes changes followed by an opportunity to share feedback or ask questions. As these sessions are being held at an early stage, detailed information on permit conditions may not be available, and DEQ may not be able to address specific inquiries at this time.

We would like to hear from you. Please register for a session using the links below. After registering, attendees will receive a confirmation email containing information about joining the meeting.
