2025 Washington's Water Quality Management Plan to Control Nonpoint Sources of Pollution
What is nonpoint pollution?
Nonpoint pollution remains a key issue across Washington. Nonpoint pollution doesn't come from a single source. Instead, it comes from many sources across the landscape, for example when rainwater washes pollutants off the land and into waterways or when lack of shade-providing streamside plants contribute to increased water temperatures.
Washington's plan to address nonpoint pollution
The Dept. of Ecology's Nonpoint Program is committed to promote the actions and partnerships necessary to be successful in achieving clean and cool water while supporting communities. It takes coordinated strategies to address widespread sources of nonpoint pollution.
Washington's Water Quality Management Plan to Control Nonpoint Sources of Pollution (Nonpoint Plan) outlines Washington's statewide approach to address water quality impacts from nonpoint sources. While Ecology is responsible for the Nonpoint Plan, it encompasses our collective strategies and partnerships. It identifies roles and responsibilities across Washington state agencies for helping address nonpoint pollution. It also ensures funding that allows us and our partners to help get clean water solutions on the ground.
Updating the Nonpoint Plan
To ensure the Nonpoint Plan accurately reflects our statewide efforts, we strive to update the plan regularly in coordination with state and local partners involved in this work. The comment period will be open through August 29th. We will submit the 2025 Nonpoint Plan to the Environmental Protection Agency (EPA) by Dec. 31, 2025.
Refer to the directions below to provide your feedback. To learn more about our update process, or read the existing plan, visit our Nonpoint Plan webpage.
