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
