Mr. Lewis <br />informed the Division after the informal conference that another spill outside of the protected area had <br />occurred on the 28"' and wanted the Division to look at the area. According to Mr. Lewis, during the <br />replacement of plastic header pipes with steel pipes, an operator failed to remember that solution still <br />existed with in the pipes. There is always solution with in these pipes unless the operator used air pressure <br />to remove all the solution contained and should have placed these pipes with in the protected area or <br />placed a container before removing the fasteners. Mr. Lewis was notified that even though the spill did not <br />reach the waters of the United States and it was small, the fact that these human errors are happening with <br />such frequency does not look good for CC&V with an Amendment pending. He stated that it was a <br />contractor doing the replacement with mine people present and that this was the first such incident that <br />took place during the replacement of these header pipes. The spill area was inspected, no problem noted. <br />The contaminated soil was removed and placed on to the leach pad and the area outside of containment <br />was detoxified, samples collected for analyses. CC&V is requested to provide the procedures to be followed <br />in the future to avoid such spills by 7-31-00. <br />While in the area, the pregnant solution areas for Phase II were inspected. The low volume solution <br />transducers were reading higher than normal, still below the maximum 2 feet of head allowed. The night <br />before, while the power was turned off to place additional power wiring for the expanded pad; scale had <br />developed in the upper valve of these low volume solution collection systems, which caused to restrict the <br />flow. Before Division staff left the area, the operator corrected the problem and the readings went back to <br />normal <br />Inspected the Phase III LINED AREA. Drain Cover was being placed at the time of the inspection, no <br />problem noted. Golder QA/QC WERE PRESENT. <br />The following readings were taken from the Low Volume and high volume Pumps for phase II. <br />PHASE II LOW VOLUME SOLUTION COLLECTION TRANCDUCERS HAD THE FOLLOWING READINGS after the <br />upper valves were Leaned. <br />PUMP #1 READ .18 FEET OF HEAD <br />PUMP #2 READ .22 FEET OF HEAD <br />PHASE II HIGH VOLUME SOLUTION COLLECTION TRANCDUCERS HAD THE FOLLOWING READINGS. <br />PUMP #4 READ 30.4 FEET OF HEAD <br />PUMP #5 READ 35.7 FEET OF HEAD <br />PUMP #6 READ 35.2 FEET OF HEAD <br />I & E Contact Address <br />NAME: SCOTT LEWIS <br />OPERATOR: CCikV <br />STREET: P.O.BOX 191 <br />CITY/STATE/ZIP: VICTOR COLORADO ROR60 <br />JAMES STEVENS <br />cc: ^ CE <br />^ BL <br />^ FS <br />^ HW <br />^ HMWMD (CH) <br />^ SE <br />^ WQCD (CH) <br />^ OTHER <br />
