The state of Washington works with the Federal Energy Regulatory Commission (FERC) licensing process for hydropower dams. When an applicant requests a license, either to re-license an existing dam or for new construction, Ecology works with the utility, reviews studies, analyses and plans. If Ecology determines that water quality standards are attainable, a 401 certification is issued with conditions to ensure that the standards will be met. These conditions become part of the new FERC license.
