<br /> <br />MINE ID # OR PROSPECTING ID #M-80-244 <br />INSPECTION DATE 1/21/00 <br />(Page 2) <br />OBSERVATIONS <br /> <br />INSPECTOR'S INITIALS BK_ <br />The Division conducted a water monitoring, sampling inspection of the site on 1-21-00. <br />Present during the inspection were, Mr Phil Barnes and Mr. Mason Estes of CC&V. The main <br />purpose of the inspection was to collect quarterly water samples for wad cyanide analysis <br />from the two 24 inch under drain pipee.Since the Leak Detection trench and sump systems <br />never functioned ae designed, due to influences from surface water peculating and expressing <br />itself ae ground water in these sumps, the Division has relied on collecting and analyzing <br />water samples from these under drains to make sure, that there is no leak from the Valley <br />Leach facility to date, all the samples analyzed from these under drains had been in <br />compliance with the approved permit condition of 0.5 ppm wad cyanide. For the moat part, in <br />particular samples collected from the South Haet Under drain discharge have been below <br />detection limit.Some samples collected from the South West Under drain ( also referred to as <br />the North IInder drain by CC&V)only a trace of Wad Cyanide has been detected Since the moat <br />likeliest place for a leak from the Valley Leach Facility to express itself will be in the <br />Under drains,In addition to the operators weakly sampling of these under drains, the Division <br />has been collecting quarterly samples from these discharges, since the commencement of <br />processing solutions, in early 95. Two liter samples one of each from the South Hast and <br />South West ( referred to the North Under drain) by CC&V WHRH COLLECTED WITH A SPLIT TAKEN BY <br />THE OPHRATOR.Samp les were preserved iced and delivered to CDOH&E LAB the same day. <br />While on site, inspected the small sediment control pond that was placed west of the crusher <br />to replace the one located Eet of the crusher The area where the old pond was located ie <br />now part of the new haul road.The new pond is incised with in the 100year 24 hour diversion <br />ditch and ie approximately sized to handle 1.5 acre feet of water. Since it ie incised with <br />in the existing diversion, and inside the affected area, no additional warranty was deemed <br />neceseary.Inepected the Phase II low volume and high volume collection system area and <br />recorded the following readings from the High and Low volume transducers. <br />HIGH VOLUME PUMP #4 READ 25,2 FHHT OF HHAD, PUMP#5 RHAD 18.2 FHHT OF HHAD AND #6 RHAD 22.2 <br />FHHT OF HHAD. LOW VOLUMH PUMP #1 RHAD .43 AND #2 RHAD .19. Mr.HStes was notified to watch the <br />High Volume Pump # 4 beacuse it never always had read at or below even pump #5. Pump #6 was <br />the one that usually reads the highest. He agreed to do so and leave a message if a problem <br />was noted. Inspected the Phase III area. The LDS#4 pipe extension is now complete. The 3 feet <br />concrete ae approved in the field has been poured in the Boylan shaft. No problem noted. <br />I & E Contact Address <br />NAME: SCOTT LEWIS <br />OPERATOR; CC6V <br />STREET :P.O.BOX 191 <br />CITY/STATE/:VICTOR, C0.80860 <br />^ HMWhID (CH) <br />cc: James Stevens <br />^ CE <br />^ BL <br />^ FS <br />^ HW <br />
