2. The designated operator/lessee will be required to complete a certain <br />number of wells as dedicated hydrologic monitoring wells. These wells <br />will supplement the proposed monitor wells and will be located outside the <br />well field and zone of influence of subsidence, so they are effective <br />throughout entire mine life. The number and location of the dedicated <br />hydrologic monitoring wells will be submitted by the applicant and <br />approved by the authorized officer before initiating construction of the <br />approved action. Monitoring of the groundwater will commence at least 6 <br />months prior to the start of mining. <br />3. The designated operator/lessee will be required to monitor four <br />groundwater zones: the unconfined water bearing zone (perched aquifer), <br />the A-groove of the upper aquifer, the base of the lower aquifer, and the <br />B-groove of the Lower aquifer. The monitoring well(s) shall be equipped <br />with a continuous graphic or other appropriate water level recorders. The <br />well(s) shall be sampled two times, 1 week apart, for major and minor <br />components, as soon as completed and cleaned out properly. Sampling for <br />major components will be conducted at least once a month beginning 6 <br />months prior to and continuing throughout mining operations, and minor <br />components will be sampled annually. Monthly sampling shall continue for <br />a period of up to 3 years (at the discretion of the authorized officer) <br />after project cessation. Any deviation from baseline condition effects <br />detected within the monitored zones during operations shall be reported to <br />the authorized officer. Sampling frequency will be increased to at least <br />once a week if effects to the monitored zones are recorded. The weekly <br />samples will be analyzed for the field measurements and major components. <br />The first weekly sample will be analyzed for minor components. If <br />significant deviations from the baseline are recorded in the minor <br />components, analysis of samples Eor minor components will continue. <br />Analysis for only those minor components which show a significant <br />deviation from baseline will be required. <br />Unless otherwise authorized by the authorized officer, the well(s) shall <br />be sampled for the following: <br />Field Measurements (Honthly) <br />temperature <br />pH <br />Lab Analyses - Ma.ior Components (Honthly) <br />total dissolved solids alkalinity <br />bicarbonate carbonate <br />conductivity <br />sodium <br />Minor Components (Sample initially and if aquifer system is affected) <br />arsenic aluminum cadmium <br />manganese selenium barium <br />chromium nickel vanadium <br />beryllium copper strontium <br />molybdenum bismuth lead <br />zinc mercury bromide <br />I <br />S <br />
