About this file
The document is a detailed technical drawing (DD-20339-55) for the U.S. Army Corps of Engineers' The Dalles Lock and Dam Columbia River Powerhouse Oil Accountability project. The drawing specifically focuses on the Main Unit 10 Turbine Guide Bearing Sump installation, with detailed specifications for magnetostrictive level sensors, vibration dampers, and oil monitoring equipment. Key technical requirements include using two-ferrule mechanical grip fittings, ensuring no contaminants enter oil-filled equipment, mounting a level sensor probe 1/2" to 1" above the bottom surface of the turbine guide bearing sump, and using a remote-mounted head with 25 feet of cable.
The drawing is part of a larger project to improve oil accountability and monitoring at the Dalles Dam, with the goal of minimizing potential oil releases into the Columbia River. The project involves installing automated systems to more consistently and reliably track oil levels in approximately 400,000 gallons of powerhouse oil, fulfilling requirements from a 2014 settlement agreement with Columbia Riverkeepers. The technical drawing provides precise installation instructions and notes for contractors, emphasizing careful verification of conditions, cleanliness standards, and specific mounting requirements for new monitoring equipment.
