Puget Sound nutrient reduction grants program
The Puget Sound Nutrient Reduction (PSNR) grant program helps municipalities prepare and plan for future wastewater treatment facility upgrades and implement operational modifications necessary to maximize nutrient removal from existing treatment processes. This grant program provides affected municipalities with financial assistance to address the Puget Sound Nutrient General Permit requirements. Eligible applicants for funding include the 43 municipalities that operate the 58 wastewater treatment plants that discharge to Puget Sound and are subject to the permit. This year, the PSNR grant is part of the Water Quality Combined Funding Program.
