12-05-1997 d:22PM FROM ENG. WEST ELK MINE 970 9295050 P. 10 <br />West Elk Mine <br />Monitoring section of the permit document- Continuous recording is accomplished through use <br />~. of Stevens Type F continuous recorders. Field data is maintained and compiled at the West Elk <br />mine office. Surface water monitoring sample measurements include field pazameters, and <br />laboratory parameters as identified in Ta~~alsv~$. Field parameters of temperature, pH, <br />conductivity, dissolved oxygen, and turbidity aze~procured at the surface water sampling point <br />by selecting a grab sample volume from surface water flow and measuring the sample for the <br />parameters using standard instruments which !rave been calibrated in the field daily. Samples <br />for analysis of laboratory parameters are collected by filling a clean pre-fixed sample bottle from <br />non-aerated flow. Sample bottles are capped, labelled, placed on ice, and vansported to the <br />laboratory for analysis. All equipment is rinsed before and after sampling with distilled water <br />as well as sample water prior to measurement of sample parartteters. <br />Tyvica/ Hvdro/oaic Samp/ing Methods-Sorinos <br />Springs are measured seasonally as described on page 2.05-74. Monitoring measurements <br />include spring flow, field parameters, and laboratory parameters. In sampling springs, a <br />location is selected, which approximates a channel as closely as possible. A step may be cut into <br />the channel base [o facilitate positioning of the container measuring volume. Flow measurements <br />are [aken through the use of a timed volume approach. The field technician times the spring <br />flow into a specific measured volume container, establishing flow rate. Several measurements <br />are taken and averaged prior to reporting. Field parameters of temperature, pH, and <br />conductivity aze procured at the spring by selecting a sample volume from the flowing spring <br />and measuring the sample for the parameters using standard instruments which have been <br />calibrated in the field daily. Samples for analysis of laboratory parameters per ~Tabty~~. <br />are collected by filling a clean, pre-fixed sample bottle from non-aerated spring flow. Care is <br />taken to minimize any increases in turbidity. Sample bottles aze capped, labelled, placed on ice, <br />and transported to the laboratory for analysis. <br />ypica/ Hydio%aic Samn/inn Methods-Ground Water <br />Ground water monitoring wells are measured seasonally as described on page 2.05-75. <br />Monitoring measurements include field and laboratory pazame[ers as identified in ale-T!£ <br />5. Static water levels are measured fast at each well. in obtaining samples from ground water <br />wells, the field technician samples each well the same way each time. In general, the ground <br />water wells at West Elk do not exhibit recovery within the time necessary to complete sampling. <br />For this reason, as explained during the 1993 permit renewal, three casing volumes of water are <br />not removed from the wells. A PVC thief with a brass foot valve is used to obtain samples. <br />The bailer is rinsed with distilled water before and after each sample. After rinsing, the bailer <br />is gently lowered into the water column in the well. The sample is obtained, striving to disturb <br />the well water column as little as possible during sampling and retrieval. Prior to measurement, <br />instruments and equipment (filters and instruments) ate rinsed with distilled water. Field <br />2.05-79 6/93 PR06: 11 /96 MR202 ~ PR07R Revired Dec. ]997 MR208 <br />
