401 Water Quality Certifications for hydropower licenses

New 401 Certification

We issued a new Section 401 Water Quality Certification with conditions for Meyers Falls Hydroelectric Project. Hydro Technology Systems’ FERC license must meet Washington State’s water quality standards and other requirements under State law. These conditions are similar to what we require for certifications of non-federal and federal hydroelectric dams across the State to ensure water quality measures are in place to meet standards.

Previously we accepted public online comments on the application and draft 401 Certification for Meyers Falls Hydroelectric Project Federal Energy Regulatory Commission (FERC) license (No. 2544). 

When an applicant requests a license, either to re-license an existing dam or for new construction, we work with the utility to review studies, analyses, and plans.

If we determine that water quality standards are attainable, a 401 Water Quality Certification is issued, with conditions to ensure that the standards will be met. These conditions become part of the Federal Energy Regulatory Commission (FERC) license.

401 Guidance Manual

The Water Quality Certifications for Existing Hydropower Dams Guidance Manual spells out our expectations of applicants who want us to certify that a hydropower project meets Washington's water quality standards. This manual is useful for utility districts, local governments, tribes, and the public.
