These wells <br />will supplement the proposed monitor wells and will be located outside <br />the 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. Honitoring 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 zon~as: 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. <br />The well(s) sha:Ll 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 component:> will be conducted on a quarterly schedule beginning 6 <br />months prior to and continuing throughout mining operations, and minor <br />components will be sampled annually. Sampling shall continue Eor a <br />period of up to 3 years (at the discretion of the authorized officer) <br />after project cessation. My deviation from baseline condition effects <br />detected within the monitored zones during operations shall be reported <br />to the authorized officer. Sampling frequency will be increased to at <br />Least once a weak if effects to the monitored zones are recorded. The <br />weekly samples will be analyzed for the field measurements and major <br />components. ThE: first weekly sample will be analyzed for minor <br />components. If significant deviations from the baseline ace recorded in <br />the minor components, analysis of samples for minor components will <br />continue. Mal)~sis for only those minor components which show a <br />significant deviation from baseline will be required. Annually, the <br />authorized officer shall evaluate effectiveness of monitoring plan to <br />determine iE required data needs are being met. <br />Unless othec~risE: authorized by the authorized officer, the well(s) shall <br />be sampled for the following: <br />Field Heasurement:s (Honthly) <br />temperature pH conductivity <br />Lab Malvses - Haior Components (Quarterly) <br />total dissolved solids alkalinity sodium silica <br />potassium chloride magnesium fluoride <br />calcium sulfate boron strontium <br />Minor Components (Sample initially and annuall <br />arsenic aluminum cadmium <br />manganese selenium barium <br />chromium nickel vanadium <br />beryllium copper lead <br />molybdenum mercury bromide <br />zinc <br /> <br />
