EXH AR025095: Application Site Certification — Wallula Power Project Vol. 1

This document is an Application for Site Certification for the Wallula Power Project in Washington State, submitted by Wallula Generation LLC to the State of Washington Energy Facility Site Evaluation Council. The application details water management plans for the proposed power plant, including how stormwater runoff from the 66-acre site will be captured, routed through oil/water separators, and reused in the plant's cooling tower basin. The applicant argues that this stormwater reuse strategy will reduce groundwater withdrawals from the local gravel aquifer with no net regional impact on water resources.
