The Washington State Department of Ecology is accepting comments about two permits connected with construction of the Pateros-Twisp powerline.
The Okanogan County Public Utility District has applied for permits for a construction stormwater permit as part of the National Pollutant Discharge Elimination System as well as a state waste-discharge permit.
Construction of the 27-mile powerline will involve almost 38 acres of soil disturbance for construction activities and roads. Runoff could affect the Methow River, wetlands and irrigation drainage, according to Ecology.
Ecology reviews public comments and considers whether discharges from this project would cause a measurable change in water quality and, if so, whether the project is necessary and in the overriding public interest.
People may submit comments to Ecology’s Water Quality Program, Construction Stormwater, P.O. Box 47696, Olympia, WA 98504-7696. For more information, contact Amy Moon at Ecology at (360) 407-6467.
