CM0001662 <br />• second phase began in late January of 1996 under a self mining program <br />initiated by Climax. This operation was suspended in April of 1996 to allow for <br />spring runoff. The third and final campaign occurred between July and October <br />of 1996. This final effort was completed on October 4 with the removal of the <br />last load of tailing. <br />The ultimate success of this project is considered to have been met through the <br />use of hoe excavation equipment, capable of reaching above and below the <br />working deck, and the use of 6-wheel drive trucks. <br />Total volume of tailing removed amounted to 1,041,300 cubic yards. <br />• Dam Modifications <br />1. Outlet Facilities <br />Project included the installation of a conduit through the reservoir to facilitate <br />delivery of impounded water. The specifics of this installation were approved <br />through Division of Minerals and Geology and State Engineer review processes. <br />2. Spillway Improvements <br />This project is currently in the design and approval process with the State Engineer. <br />Construction is scheduled for July, 1997. <br />3. 4-Seep Return Modification <br />Modification of the seepage return system has been approved by the Division of <br />Minerals and Geology. The excavation in the crest of 4-Dam at the south abutment <br />was suspended in late 1996 to avoid backfill and compaction of frozen material. <br />Project is scheduled for completion by late June of 1997. <br />An Emergency Preparedness Plan has been submitted and approved for the reservoir <br />as required by the Office of the State Engineer. <br />• Pollution Prevention <br />1. Robinson Seep Cutoff Wall <br />This wall was constructed as an Environmental Protection Facility to capture and <br />return all groundwater to process above Eagle Park Reservoir. The wall was <br />constructed between September, 1996 and May, 1997. <br />2. Robinson Seep Surface Water Return System <br />This seep return system has been in place for many years. The system operates to <br />return surface water seeps at the toe of Robinson Reservoir back to the reservoir. <br />• <br />3 .
