401 Guidance Manual

The Water Quality Certifications for Existing Hydropower Dams Guidance Manual spells out Ecology's expectations of applicants who want us to certify that a hydropower project meets Washington's water quality standards. Utilities, tribes, the public and Ecology staff will find it useful.

We considered public comments during the writing of this guidance. Here are the Comments and Responses to the final draft Water Quality Certifications for Existing Hydropower Dams Guidance Manual (PDF).
