Animas -La Plata Project <br />Feb 13, 2013 Draft Transfer Inspection Report <br />TRANSFER ISSUE <br />STIPULATION <br />There is no safe way to <br />Reclamation will relocate the 3" ball valve, currently in the air <br />evacuate air /pressure from <br />chamber vault, and muffle. <br />chamber <br />Compressor shows a power <br />Reclamation will investigate breaker 52 -6; and evaluate, and <br />interrupt failure <br />repair this interrupt issue. <br />The access door has a <br />Reclamation shall repair damaged concrete at access door <br />damaged threshold <br />threshold and asphalt settlement, per Section C (2) above. <br />Backaround: Reclamation provided a method to release air chamber pressure during the <br />draining of RBIC. Further modifications are necessary to reduce the noise level during this <br />operation. <br />15. Durango Discharge Flow Meter <br />Approximately 160 feet south of the spherical air chamber is located a flow meter structure <br />for the Ridges Basin Inlet Conduit. <br />TRANSFER ISSUE <br />STIPULATION <br />Flowmeter software is out <br />Reclamation will install new Accusonic software. <br />of date <br />ensure they meet specifications. <br />16. City of Durango Discharge Manifold <br />The steel manifold starts at two 18" diameter tees; one located downstream of Unit 1 and <br />one located downstream of Unit 2. The tees connect to a 20" diameter steel pipe. The 20" <br />diameter steel pipe connects to the 30" diameter steel discharge manifold. This 30" <br />diameter steel pipe extends from the pumping plant structure, under and past the 9' <br />diameter air chamber, to the 30" diameter line pipe. It connects to the line pipe at an <br />insulating flanged joint. <br />17. City of Durango Air Chamber <br />At the southeast corner of the pumping plant is located the flow measurement structure <br />and 9' diameter cylindrical air chamber for the City of Durango water supply pipeline. <br />TRANSFER ISSUE <br />STIPULATION <br />The air chamber has never <br />Reclamation will operate and test air chamber and compressor to <br />been commissioned or <br />ensure they meet specifications. <br />tested <br />The E x E coupling appears <br />Reclamation shall verify that the E x E coupling is aligned. <br />to be misaligned <br />18. Primary Electrical System <br />15 -kV Metal -Clad Switchgear <br />The double -ended switchgear includes three 3000 -amp drawout -type circuit <br />breakers, two disconnecting fuses, and two potential transformers. It is configured <br />to receive power from two power transformers in a switchyard adjacent to the <br />Transferred Works Inspection 22 Animas -La Plata Project <br />
