Ecology Releases New Construction Stormwater General Permit
The Washington Department of Ecology has reissued the Construction Stormwater General Permit to take effect on January 1, 2021. The permit authorizes stormwater and approved non-stormwater discharges associated with construction activity. Permit coverage is required for the following:
- Ongoing construction sites that are covered under the existing permit
- Construction sites that disturb one acre or more of land and discharge stormwater off site or into surface waters of the state
- Construction sites of any size that the Department of Ecology determines will be a significant contributor of pollutants or will cause a violation of any water quality standard
