TDA Oil Accountability Contract Drawings - Vol 1d of 4.pdf

The file "TDA Oil Accountability Contract Drawings - Vol 1d of 4.pdf" appears to be a technical drawing volume related to a U.S. Army Corps of Engineers (USACE) Portland District project at The Dalles Dam. The project focuses on improving oil accountability and monitoring systems to minimize potential oil releases into the Columbia River, addressing requirements from a 2014 settlement agreement with Columbia Riverkeepers.

The contract is a competitive, firm-fixed price (FFP) solicitation targeting improvements in oil monitoring for approximately 400,000 gallons of oil at the TDA powerhouse. Key objectives include increasing automation of instrumentation for tracking oil in equipment and containers, enhancing early leak detection, and reducing operations and maintenance costs. The project will replace current manual monitoring methods (visual observations, sight glasses, leak checks) with more sophisticated automated tracking systems, aligned with the Portland District's Environmental Policy 200-1. The solicitation number is W9127N26RA004, with associated drawings released on 18 November 2025, and a projected contract completion date of 14 November 2025.
