We are requesting comments on our proposal to develop a Puget Sound Nutrients General Permit. This permit would control nutrient discharges from domestic wastewater treatment plants (WWTPs) that discharge to marine or estuarine waters of Puget Sound.
The primary purpose of this public comment period is to get feedback on whether a general permit is an appropriate tool to control nutrients in discharges from WWTPs to Puget Sound. No permit language has been drafted at this time. The alternative to a general permit is to include nutrient control requirements in each WWTP’s individual permit. See our general permits page for more information.
After the close of the comment period, we will consider all comments and make a decision on whether to develop a general permit.
Excess nutrients can cause too much plant and algae growth which ultimately reduces the amount of dissolved oxygen in the water. Many parts of Puget Sound have oxygen levels that fall below what is needed for marine life to thrive and do not meet our water quality standards. We require WWTPs to control nutrients consistent with the Clean Water Act and Washington’s Water Pollution Control Act.
