DMG Permit No. M-88-112 <br />Monthly Sampling - <br />Dear Mr. Dillie: <br />All required sampling was completed during the month of November. Enclosed are analytical <br />reports from Sangre De Cristo lab for the recent bi-weekly and monthly sampling periods as <br />specified in the April 1992 Abatement Plan. Analysis that have not been received will be forwarded <br />to you as I receive them. <br />The NANO/RO water treatment plant operaled intermittently during the month. A total of 5,855,000 <br />gallons of water was treated and discharged into Riot Seco during the month of November. <br />Work continued on the sformwater diversion on Waste Rock "C" and the project is approximately <br />60% complete. <br />Construction of the pipeline from the evaporation system collection pond to the tailings <br />impoundment is nearly complete. <br />All surface water stations were inspected and RS-4 and RS-6 were found to be dry. <br />Vacuum on the lysimeters was verified and no water was present to sample. <br />When we checked the piezometers on the main embankment of the tailings impoundment on <br />1 1 /29/99, the piezometers were dry or contained below 12 inches of water. <br />The two west pit piezometers were measured for depth to water on 1 1 /30/99, with the following <br />result: BF-1 was 14.85 ft and BF-2 was 18.45 ft. The other piezometers in the West Mine area were also <br />checked with the following result: PW-1 was 18.15 ft, PW-2 was 17.88 ft, PW-3 was 25.68 ft and PW-4 <br />was 26.24 ft. <br />The underdrain was measured at approximately 32 gpm. <br />the collection pond's leak detection system was sampled and pumped dry. The leak was <br />measured at approximately 34 GPAD. <br />The evaporation system was in operation most of the month with the supersprays. Down time was <br />attributed to routine maintenance or pump repair. <br />A SUBSIDIARY OF BATTLE AfOUNTALV GOLD COh1PANY' <br />P.O.
