~ III IIIIIIIIIIIIIIII ~ <br />BATTLE MOUNTAIN GOLD COMPANY <br />May 24, 1996 ~j ~r~ ~ 4 ~99~ <br />Mr. Jim Dillie c~ar~ocomANN <br />Division of Minerals and Geology <br />1313 Sherman Street, Room 215 Division o. I~m~o~aw v ^ ~°~°~'• <br />Denver, Colorado 80203 <br />Subject: Battle Mountain Resources, Inc. -San Luis, DMG Permit No. M-88-1 12 <br />1995 Annual Report and May 8, 1996 Inspection Report <br />Dear Mr. Dillie: ~N <br />This letter is in response to your letter dated March 29, 1996 and the inspection or May 8, <br />1996. <br />The letter begins with the underdrain and why it was not monitored in January, FE:bruary, <br />March, April, May, or June of 1995. The Division is aware that in April 1995, it was ~Jiscovered <br />that many environmental tasks were not being completed by the BMRI employee in <br />charge of such tasks. After this employee left in April 1995, BMRI was brought before the <br />board in May 1995 to answer to These issues. In the meantime, BMRI had hired a consultant <br />to review all documents to evaluate what the environmental duties were. Everyone at this <br />time, including the Division, were rushing io determine what else had been neglected. It <br />wasn't until July 1995 that it was determined that the underdrain flow must be monitored <br />and a means of monitoring it were found. Therefore, BMRI feels that this issue is still a part of <br />the second Notice Of Violation. <br />Your second comment in the letter is in regards io piezometers. This problem originally <br />siemined from the problems stated above. TR-023 was implemented in order for all parties <br />to better understand this issue. TR-016 was revised in part under TR-023 in order that the <br />confusion over piezometers be eliminated. The Division has been aware during he <br />approval of TR-023 that there has been wafer in some of the piezometers. The reauiremeni <br />in TR-016 that the Division be notified about water in the piezometers is not clear ~]s to the <br />amount that triggers such notification. According to Dave Hallman, P.E. of Steffen, <br />Robertson, and Kirsten, water becomes trapped in the dead space above fhe end cap <br />and below the level of the lowermost screen slots in the piezometer casing. Decd storage <br />can be typically 4 - 12 inches. Therefore, we don't typically report piezometer readings of <br />less than 12 inches in the bottom of the piezometers. <br />P.O.
