Puget Sound Nutrient General Permit Preliminary Draft

Informal Comment Period

Jan. 27, 2021 - March 15, 2021, 11:59 p.m.

We invite your comments and are pleased to announce the preliminary draft Puget Sound Nutrient General Permit. 

The Puget Sound Nutrient General Permit will establish nutrient reduction practices for wastewater treatment plants (WWTP) to prevent excess nutrients and protect Puget Sound. The proposed permit will cover nearly 60 public WWTPs that already have individual National Pollutant Discharge Elimination System (NPDES) permits. This General Permit will focus only on controlling nutrients and work in conjunction with the broader individual permits.

Excess nutrients can cause too much plant and algae growth which ultimately depletes dissolved oxygen. Many parts of Puget Sound have oxygen levels that fall below the concentrations needed for marine life to thrive and concentrations that are below the state’s water quality criteria. 

This National Pollutant Discharge Elimination System (NPDES) water quality permit will help control the discharge of nutrients from domestic wastewater treatment plants, following the federal Water Pollution Control Act and state Water Pollution Control laws.
