water balance will be recorded as frequently <br /> q tly as necessary in order <br /> to update the disposal area mass and water balance. This information <br /> will include precipitation, evaporation, } <br /> P pumping rates and hours,. <br /> tailings level , water pond volumes, seepage volumes, and slurry <br /> densities. In addition, bi-annual surveys of the embankment <br /> configuration and disposal area to evaluate incremental and total <br /> volumes of deposited tailings will be performed. <br /> A rain gauge and evaporation pan will be installed and <br /> maintained in order to monitor the volumes of precipitation and <br /> evaporation. This information, combined with a mass and water <br /> balance simulation update, will be used in modifying the tailings <br /> disposal area operation to suit natural and operating conditions. <br /> 2.4 Hydrolooic System <br /> The objectives of this monitoring <br /> program are to identify any <br /> changes in the quantity and quality of surface water and groundwater <br /> during the life of the San Luis Project. The monitoring process will <br /> involve four separate aspects: 1) groundwater levels, 2) <br /> groundwater quality, 3) surface water quantity, and 4) surface <br /> water quality. <br /> Knowledge of changes in the hydrologic environment, together <br /> with baseline data already available, will permit evaluation of the <br /> hydrologic impacts of the mining operation. <br /> 2.4.1 Groundwater <br /> Groundwater will be monitored at the locations of monitor <br /> wells shown on Figure G-1 of the amendment application. Seven <br /> wells have been established at various levels in the area of <br /> the tailings disposal area. All but one of these wells are <br /> currently dry. An additional number of wells have been <br /> 1 <br /> 71 01 324 <br />
