The Dalles Oil Accountability Contract Drawings.pdf

The file is a PDF containing engineering drawings related to the Dalles Dam Oil Accountability Measures contract, issued by the U.S. Army Corps of Engineers (USACE) Portland District. The project is a competitive, firm-fixed price contract aimed at improving oil monitoring and minimizing potential oil releases at The Dalles Dam, located on the Columbia River in Oregon. The primary objectives include developing an Oil Accountability Plan (OAP) to track approximately 400,000 gallons of oil in the powerhouse, replacing current manual monitoring methods with automated instrumentation systems that can more accurately track oil levels in equipment, bulk storage containers, and high-risk areas.

The contract stems from a 2014 settlement agreement with Columbia Riverkeepers and is designed to fulfill the Portland District's Standing Environmental Policy 200-1 on Oil Accountability. The solicitation is set for 14 November 2025, with 13 total drawing files attached as of 18 November 2025. The project seeks to enhance oil leak detection, improve monitoring timeliness, and reduce operations and maintenance (O&M) costs by implementing more sophisticated tracking and measurement technologies across the dam's critical oil-containing infrastructure.
