Water quality general permits

General water quality permits regulate specific discharge categories that release treated stormwater or wastewater to either surface or groundwater.

Categories of general permits include:

If you do not see your industry covered by one of the general permit categories, you may need coverage under an individual discharge permit.


Preliminary determination to develop a new general permit

We are proposing to develop a Puget Sound Nutrients General Permit. The purpose of the general permit will be to control nutrient discharges from domestic wastewater treatment plants that discharge to marine or estuarine waters of Puget Sound.

We accepted comments on using a general permit to control nutrient discharges from Aug. 21, 2019, until  Oct. 21, 2019. The comment period is now closed. You may view the comments we recieved online.

For more information on the nutrients issue and the permit proposal, read our focus sheet

If we move forward with a general permit, we will prepare draft permit language and provide it to the public for comment. If we decide not to move forward with a general permit, we will post a public notice of that decision. To stay informed on this effort, join the Nutrient Permit listserv.
