TDA Oil Accountability Contract Drawings - Vol 3 of 4.pdf

The file is a technical drawing document (Volume 3 of 4) related to the U.S. Army Corps of Engineers' The Dalles Dam Oil Accountability Measures contract. The project aims to improve oil monitoring and accountability at the Dalles Dam (TDA), located on the Columbia River between Oregon and Washington. The primary objectives include enhancing oil leak detection, automating instrumentation for tracking oil in equipment and storage containers, and reducing environmental risks associated with approximately 400,000 gallons of oil at the powerhouse.

The solicitation is for a competitive, firm-fixed price (FFP) contract stemming from a 2014 settlement agreement with Columbia Riverkeepers. The project will implement an Oil Accountability Plan (OAP) to systematically monitor oils and greases used in turbines, wicket gate bearings, and fish-way equipment. Key improvements include increasing monitoring accuracy, automating level tracking, and reducing operations and maintenance (O&M) costs while complying with the Portland District's Environmental Policy 200-1. The solicitation includes 13 total drawing files, with an anticipated contract execution date of 14 November 2025.
