Wells Hydroelectric Project FERC License No. 2149
The goal of the Water Quality Management Plan (WQMP) is to protect the quality of the surface waters affected by the Wells Hydroelectric Project (Wells Project) with regard to the numeric criteria.
Public Utility District No. 1 of Douglas County (Douglas PUD), in collaboration with the Aquatic Settlement Work Group (Aquatic SWG), has agreed to implement measures in support of the WQMP. Reasonable and feasible measures will be implemented in order to maintain compliance with the numeric criteria of the Washington State Water Quality Standards, Chapter 173-201A WAC.
Actions include providing real time temperature data at boundary locations around the Wells Project, monitoring total dissolved gas (TDG) during fish bypass and non-bypass periods, and providing this data to the public. Douglas PUD is working on a ten year TDG compliance schedule to ensure that the Wells Project remains in compliance with Washington Administrative Code standards regulated by the Washington State Department of Ecology.
The measures presented within the WQMP are designed to meet the following objectives: 1) Maintain compliance with state WQS for TDG. If non-compliance is observed, the Aquatic SWG will identify reasonable and feasible measures, which will be implemented by Douglas PUD; 2) Maintain compliance with state WQS for water temperature. If information becomes available that suggests non-compliance is occurring or likely to occur, the Aquatic SWG will identify reasonable and feasible measures, which will be implemented by Douglas PUD; 3) Maintain compliance with state WQS for other numeric criteria. If information becomes available that suggests non-compliance is occurring or likely to occur, the Aquatic SWG will identify reasonable and feasible measures, which will be implemented by Douglas PUD; 4) Operate the Project in a manner that will avoid, or where not feasible to avoid, minimize, spill of hazardous materials and implement effective countermeasures in the event of a hazardous materials spill; and 5) Participate in regional forums tasked with improving water quality conditions and protecting designated uses in the Columbia River basin.
