f ~ •e ~~ vicinity of the tailings disposal area have been consistently found to be dry except monitoring well M-9 which has indicated a consistent water level at approximately 144 feet below the surface. BMR conducts additional monitoring at other Wells outside of the permit boundary as required by the water right decree (Dos Hermanos and San Luis wells). Copies of all data obtained since commencement of tailings deposition have been submitted previously as part of BMR's quarterly reports and additional copies are attached. To date, monitoring o~ wells has not identified any changes in water quality which woul indicate a release or potential release from the facility. In response to the current circumstances, BMR con ucted monitoring of all wells in the vicinity of the tailing facility. Only one well (M-9) located downgradient from the tail ngs facility has water standing. As noted above, the dept to water in M-9 is approximately 144 feet. A sample from M-9 w s gathered on April 3 under the supervision of Bruce Lytle, a hyd ologist with Halepaska Associates. The results are enclosed a d, consistent with previous findings, confirm that no rel ase has occurred from the tailings facility. MLRD representat ves were present and collected a sample for cyanide analysis us ng another lab. BMR has not been apprised of those analytical re ults. Monitoring wells M-6, 7 and 8 are also located below t e tailings facility adjacent to M-9 but have been consistently dr and, therefore, no samples were obtained. Surface Water Monitoring Sampling sites are established on Rito Seco Creek above and below the project area and quarterly samples are colle ted. Sample results collected to date do not indicate any r lease of cyanide process solution. The analytical results refl ct trace cyanide readings at R2-1 (River Station) above the pro ect area, and well locations M-1 and D87-24 which are located ne t to the West Pit mine area. RS-19 was a duplicate of RS-1. G ven their location upgradient of any cyanide use at the facility„ BMR believes these values do not reflect cyanide detectionlbut rather are the result of either a sampling and/or analytical error. Surface water monitoring results are also attached. Air Ouality Monitoring The Department of Health Air Pollution Control Di lsion required San Luis to install air quality monitoring sues to monitor particulate emissions. Therefore, the monitoring results from these stations do not generate data related to cy~nide. BMR is currently in compliance with applicable state and f deral emission standards as well as applicable worker health and safety standards.
