• No samples were collected during 2002 from these SAE points. <br />Coal Member of Mesaverde: <br />All previously monitored drill holes have now collapsed and are no longer monitored. The fmal monitorable hole, DH- <br />60, was monitored by a long tube used to pressurize the hole and produce an estimate of water level. This mbe has <br />become ineffective. The removal of these sights is explained in TR-34. <br />Surface Water Monitoring Stations: PONDS <br />East Roatcap Creek -Fifteen ponds in the East Roatcap Creek drainage were monitored during 2002 (refer to Table 1 <br />and Map No. 4-1). Ponds were monitored quarterly for water levels and field parameters if they were discharging. <br />No evidence of mine impacts was noted. During 1994 retreat mining was done under Ponds ] 0-I, 10-2, 10-3, 10-4 and <br />0-11. Advance mining occurred under ponds 88 and 14-2 in 1997. The East Roatcap Creek Ponds were physically <br />intact throughout 2002 and showed no subsidence effects. <br />West Roatcap Creek -Two ponds m the West Roatcap Creek drainage (refer to Table 1 and Map No. 4-1) were <br />monitored during 2002. The ponds were monitored quarterly for water levels and field parameters if they were <br />discharging. No evidence of mine impacts were noted. The West Roatcap Creek ponds were physically intact <br />throughout 2002 and showed no subsidence effects. <br />Steven's Gulch -Five ponds were monitored within the Steven's Gulch drainage (refer to Table 5 and Map No. 4-I). <br />Ponds 85 and 13-7 were monitored quazterly for water levels and field pazameters. Pond 85 was undermined by Panel <br />B in 1992. Pond 13-7 was also undermined during 1992. No subsidence impacts or other irregularities were evident <br />at either of these locations during 2002. <br />Conclusion <br />Hydrologic monitoring was extended into the northern portion of the East Roatcap Creek drainage during 1993 to fit <br />newly acquired lease areas and revised mine plans. Mining operations were suspended during December 1997 and have <br />not resumed. Hydrologic monitoring conducted during 2002 did not show mine related impacts to the local hydrology <br />were occurring. All ofthe monitored locations exhibited characteristics and patterns similar to previously observed data. <br />Water quality remains good overall and no physical impacts have been noted at any of the monitored locations that <br />would suggest adverse effects associated with the historical mining operations of the Bowie No. 1 Mine. <br />• <br />
