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 proposes to renew the draft 1200-C permit which regulates discharges from construction activities to surfaces waters of the state. The current 1200-C construction general permit expires Dec. 14, 2025. This permit renewal is a replacement of the previous 1200-C construction stormwater general permit issued on Dec. 15, 2020.
DEQ invites the public to provide comments through Oct. 27, 2025 at 5 PM. Comments should be sent to 1200cpubliccomment@deq.oregon.gov.
DEQ will also host a virtual public hearing on Oct. 23, 2025 at 9 am.
