C-1106C <br />Water Division 5, DAMED: 370103 <br />SUBJECT: Winter Shut Down of the Construction Project <br />Dear Mr. Maly: <br />0 <br />4 r <br />Ipma S. l achimd <br />=D4= <br />We appreciate that you have kept this. office informed of the construction progress of the <br />seePwater pipeline installation project at the Climax Moly No. 4 Dam and for informing us of the <br />proposed winter shut down of the project. It is our understanding that a relatively awn cut has been <br />made through the dam embankment at the left abutment to facilitate the installation of the <br />aforementioned seepwater pipeline. Due to winter conditions at the site, the installation of the pipeline <br />and the backMing of the excavated trench can not be properly executed in accordance with the <br />approved plans and specifications. Therefore, the construction of this portion of the pipeline is planned <br />to be postponed until neat spring after the proposed backM materials for the trench bane thawed. <br />In your letter dated December 3, 1996, you requested that we allow the small breach section in <br />the dam embankment at left abutment to remain open until the spring of 1997,.at which time the pipeline <br />can be installed and the trench properly backfiilled. This condition is acceptable; however, this <br />acceptance is contingent on the following items: <br />• The Eagle Park Reservoir shall remain relatively empty during the winter months_ <br />The Robinson Dam and Reservoir should be operated such that no dischargc or spillage occurs <br />into the Eagle Park Reservoir during the snowmelt runoff neat spring or until the breach in the <br />Climax Moly No. 4 Dam has been backfilled. <br />C7 <br />
