Surface water monitoring sites 1, 2, 5 and 6 are sampled monthly, from March <br />through October for flow, temperature, pH and conductivity. The 45 parameters <br />listed in Table 7-47 are sampled three times between March and September, in <br />the same manner as described above for NPDES monitoring sites. <br />Surface water monitoring sites 10, 11, 12 and 13 are sampled on a monthly <br />basis from May through September for the parameters listed on Table 7-47. <br />Samples are not taken of these sites if no flow exists at the confluences of <br />Bond Creek and Cow Camp Creek with Fish Creek. <br />Native Springs <br />Four native springs exist within the permit area: Springs #1, 2, 3 and 5. <br />Spring #4 is outside the permit area and is no longer sampled. These native <br />springs are sampled during May of each year for the parameters listed in <br />Table 7-47. <br />Spoil Springs <br />Nine spoil springs exist in the permit area. Eight of these spoil springs <br />(#2, 3, 4, 5, 6, 7, 8, and 9) are sampled annually after the soil has dried <br />out following snow melt and are monitored for flow, temperature, pH and <br />conductivity. <br />Spoil spring #1 is sampled bi-weekly from March to June for flow, temperature, <br />pH and conductivity and three times between March and September for the <br />parameters listed in Table 7.47 (as described above for NPDES monitoring <br />sites). <br />Stock Tanks <br />Stock tanks have been constructed in drainages on reclaimed spoils in both the <br />Wadge and Wolf Creek mining areas. The tanks are temporary to assist in <br />erosion control, as well as provide water for wildlife and livestock. Six <br />stock tanks are monitored for both the presence of water and quality of <br />water. These stock tanks are numbered T2, T5, T6, T7, T12 and T25. These <br />ponds are sampled on a monthly basis between June and September for the <br />parameters listed in Table 7-47. Sampling of the stock tanks will continue <br />through the 1992 water year, at which time Peabody Coal Company will compile <br />the data collected to determine what effect, if any, the stock tanks have on <br />the prevailing hydrologic balance. Peabody Coal Company will submit the <br />results of the study to the Division, and the requirement for future <br />monitoring will be assessed if Peabody Coal Company proposes to discontinue <br />monitoring at that time. <br />The applicant will conduct monitoring of surface water in a manner approved by <br />the Division. The monitoring plan was submitted under 2.05.6(3)(b)(iv) and <br />includes the following: (4.05.13(2)). <br />-18- <br /> <br />
