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 are currently requesting comments on the appropriateness of using a general permit to control nutrient discharges. We are accepting comments from Aug. 21, 2019, until 11:59 p.m. on Oct. 21, 2019. You may submit comments online.

For more information on the nutrients problem, the permit proposal, and how to comment, read our focus sheet. We do not currently have draft permit language. If we move forward with a general permit, we will prepare draft permit language and provide it to the public for comment.
