Moun(ain Coal Compam 1997 Annual Hydrology Report Wes EIk Mine Fork drainage basin; (3) springs and other water resources above the B-Seam in the Jumbo • Mountain area in the North Fork drainage basin; and (4) springs above the E-Seam in the Dry Fork drainage. Field water quality samples were taken three times during the water year at all stations that were flowing. On an annual basis, all stations were sampled and the samples were analyzed for a full suite of pazameters (Table 2). Baseline monitoring continued on eight springs initiated in WY96 (15-1, 15-2, E15-3, E10-2, E10-3, E10-4, 26-1 and 27-1) as well as spring J-4, which was re-initiated in WY96. Baseline monitoring was to be conducted on springs G-7 and G-8 to re-establish baseline, however these springs were sampled under the regular monitoring program. The springs will be sampled under the baseline schedule in WY98. No new springs were added to the monitoring program in WY97. MCC, in cooperation with the U.S. Forest Service District Office in Paonia, Colorado, has agreed to informally monitor the U.S. Forest Service surface water resources, as depicted on Map 3, that are located directly over panels to be mined, and within the angle-of--draw per the agreement letter in Exhibit 19C of the permit. These resources are listed in Table 3. Sampling Methods Monitoring included spring flow, field parameters, and laboratory parameters. In sampling springs. a location was selected which approximated a channel as closely as possible. A step may have been cut into the channel base to facilitate positioning of a container. Flow measurements were made by • the timed volumetric method: where a field technician times the filling of a container of known volume to determine the flow rate. Several measurements were taken and averaged prior to reporting. Field parameters of temperature, pH, and conductivity were made at the springs by collecting a sample from the flowing springs and measuring the sample for the parameters using standard instruments that were calibrated in the field. Samples for analysis of laboratory parameters per Table Z, Footnote 2 were collected by filling a clean, pre-fixed sample bottle from non-aerated spring flow. Care was taken to minimize any increases in turbidity. Sample bottles were sealed, labeled, placed on ice, and transported to the laboratory for analysis. Groundwater Monitoring There were thirty-two wells in the WY97 groundwater monitoring program and are summarized in Table 4 along with the formation each of the wells monitor. Table 5 provides more detail on the completion of each of the wells in the monitoring program. Field water quality samples were taken three times during the water year at all stations if sufficient volume was present to fill the appropriate sample containers and if the well allowed access to the formation of completion. On an annual basis, all stations were similarly sampled and the samples were analyzed for a full suite of parameters (Table 4), when conditions allowed. • 8 -03 .4 0 Page {Vrig t Water ngineers
