ORIGINAL - PUBLIC FIL& (Page 2) MINE ID # OR PROSPECTING ID #: nn_taRn-add INSPECTION DATE: t t-~5 ~~ t t 1~R INSPECTOROS INITIALS: _BK- OBSERVATIONS The Division conducted a monitoring inspection of the site In response to a telephone call from Mr. Phil Barnes Environmental recourses manager for the mine. On i 1-24-03, Mr. Barnes stated over the phone, that due to a power surge of some sort, the ground fault Interrupter For the PHASE IV low volume solution collection system pumps were turned off, and caused the low volume to exceed the two feet of head maximum required under Amendment # 8. He also stated the problem was not noted until the required rounds were made in early morning during a shift change and that it only affected the low volume pumps. Prior to the inspection Mr. Barnes explained that no one was really sure what caused the power surge that triggered the power shut off to the low volume solution collection pumps. However, he stated that there was some work that was being conducted to one of the high volume pump valves, after it triggered one of the pump shut off. Apparently after the work was completed on the high volume pump valve, no one checked to make sure the low volume pumps were on. CCBY HAS IN PLACE, TWO BACKUP GENERATORS AND A SUB STATION IN PLACE, WHICH ALLOWS THEM TO TURN ON, IN CASE OF A POWER FAILUER. This particular incident was not caused due"fo a power failure rather than a power surge that only affected the shut off of the ground fault interrupter, which is an added feature to only the Phase IV low volume pump system, Since at the request of the Division CC&V had installed a green and red light indicator, outside of the shed that houses the read out meters, for all the LOW VOLUME SOLUTION COLLECTION PUMPING SYTEM, the question was asked, why no one noticed these lights were off, prior to departing the area, after fixing the problem to the high volume pump valves? He stated he did not know why no one noticed them until the regular shift change inspection. But as of That Day, Mr. Larry Newcomer, manger of processing has instituted, checking all the low volume and high volume pumps every four hours with a logbook to indicate the time and levels for each pumps. At the time of the inspection both pumps were on and the following readings were recorded for the Phase IV HIGH AND LOW VOLUME SOLUTION COLLECTION SYSTEMS. Low volume solution collection transducer # 1 was recorded of 39.1 and 36.0 INCHES OF HYDROSTATIC HEAD. Htgh volume SOLUTION COLLECTION TRANSDUCER # 7 WAS AT 19.2 #8 WAS AT 19.3 # 9 WAS AT 19.3 AND #10 WAS AT 19.3. While in the area also collected the following readings from the high and low volume solution collection transducers for Phase I AND II, HIGH AND LOW VOLUME SOLUTION COLLECTION TRANSDUCERS. Phase I Low Volume Solution Goliecffon transducer # i was recorded ai .15 and # 2 was at .72 Phase 1 High Volume Solution Collection Transducer #1 was recorded at 36.4 #2 was at 38.1 # 3 was at38.3 Phase 11 Low Volume solution collection transducer #1 was recorded at .21 and # 2 was at .38. High Volume solution collection transducer #4 was recorded at 28.4 #5 was recorded at 29.4 and #5 was at 26.4. No major problem noted.
