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.

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. It details stormwater management plans for the 66-acre project site, including capturing rainfall and routing it through oil/water separators to a detention pond for reuse in the power plant's cooling tower. The application also addresses groundwater rights, noting that captured stormwater would reduce withdrawals from the gravel aquifer and Boise Cascade Corporation fiber farm wells.

This 2001 User's Guide from the Washington State Department of Ecology explains how to use spreadsheet workbook tools (MTCASGL and MTCATPH) to calculate soil and groundwater cleanup levels under the Model Toxics Control Act. The guide covers how to enter site-specific data—such as chemical properties, exposure parameters, and hydrogeological characteristics—to determine safe contamination thresholds. It is intended for environmental cleanup professionals working on hazardous substance remediation in Washington State.
