• Spring 10-] 0 was dry during the reporting period. Spring 10-10 was encompassed by the angle-of--draw of Panel Y <br />during October, 1993. Subsidence impacts were not apparent at either of these locations during 2004. <br />West Roatcap Creek - Fout springs were monitored in the West Roatcap Creek drainage (refer to Table 1 and Map No. 4- <br />1)during 2004. Spring 31 was monitored on a monthly basis. Flows throughout the yeaz were considered average with <br />the flow tapering off in the fall. Water quality parameters were consistent with ranges previously established for this site. <br />No mining occurred within the watershed for this spring in 2004 and no mining impacts were evident. Spring 32 was <br />monitored monthly. Spring 32 exhibited flow throughout the year however the landowner had the flow meter bypassed <br />during most of the year. T7te flow meter was bypassed by the landowner during I I of 12 monitoring events. Water <br />quality parameters were consistent with last year s sampling. Spring 10-13 was monitored quarterly. Flows, as a result of <br />a seemingly dry yeaz, were non-existent. No mining occurred during 2004 in the Springl0-13 watershed. Spring 14-4 <br />was monitored quarterly. Flows were no more that a seep during the year. No mining occurred during 2004 in the <br />Springl4-4 watershed. <br />Steven's Gulch -One spring was monitored within the Steven's Gulch drainage (refer to Table 1 and Map No. 4-1) in <br />2005. Spring 251ies below an area of the East mine inactive since 1982. This site had no measurable flows in April, <br />June, September or December. Spring 25 has been identified as an adjudicated water right within the pemrit area. <br />Two springs with ponds in the Stevens Gulch drainage, Spring and Pond 13-5, Spring and Pond 13-6 were monitored <br />quarterly in 2004. Spring and Pond 13-5 was undermined during the last half of 1992. Spring and Pond 13-6 was <br />undemtlned during the end of 1988. Neither Spring 13-5 nor Spring 13-6 had any measurable flow throughout the yeaz. <br />Terror Creek -Seven springs or springs with ponds are found within the Terror Creek drainage (refer to Table 1 and Map <br />No. 4-1) were monitored during 2004. Spring and Pond 17 is outside the anticipated extent of mining activity. Spring <br />and Pond 20 and Spring and Pond 7-I were undermined during the East Pod development, panels EP-3 and EP-4. All <br />• foot springs have extensive data collected to chazacterize the typical hydrology at these sites. However, these locatons <br />were identified and tazgeted by the Division as adjudicated water rights within the pemilt azea. No adverse mine related <br />impacts or other irregularities were noted at any of these Terror Creek Springs. <br />Surface Water Monitoring Stations: STREAMS AND DITCHES <br />Overall, adverse impacts attributable to mining were no[ evident at any of the monitored surface water stations (refer to <br />Table 1 and Map No. 4-1). Stations SW-5 (Stevens Gulch) and SW-6 (East Roatcap Creek), exhibited below average <br />flows and water quality parameters consistent with previous years data. Station SW-10 (Terror Ditch), exhibited typical <br />flows for an irrigafion ditch. No evidence of subsidence impacts in these drainages was apparent. Mining occurred in the <br />Stevens Gulch drainage upstream ofsite SW-5 during 1993 in Panel C. Panel C raining was designed and conducted to <br />prevent the development of subsidence to protect the waterway and certain shuctures in the vicinity. Data collected <br />during 2004 shows these protective measures were successful. <br />Surface Water Monitoring Stations: SMALL AREA EXEMPTIONS <br />The east mine fan level was defined as a small azea exemption since drainage from this area (refer to Map 8-1) is not <br />conveyed to a sediment pond. Three sample points were defined at this location and sampled for confomtance with the <br />NPDES discharge alteatative limitations requirements associated with dischazges occurring because of precipitation <br />events of less than the 10-yeaz and 24-hour magnitude. In these instances, settable solids and pH limitation must be met. <br />No samples were collected during 2004 from these SAE points. <br />Coal Member o[ Mesaverde: <br />All previously monitored drill holes have now collapsed and are no longer monitored. The final hole, DH-6Q, was <br />monitored by a long tube used to pressurize the hole and produce an estimate of water level. This tube has become <br />ineffective. The removal of these monitoring points is explained in TR-34. <br />Surface Water Monitoring Stations: PONDS <br />East Roatcap Creek - Fifleen ponds in the East Roatcap Creek drainage were monitored during 2004 (refer to Table 1 <br />and Map No. 4-1). Ponds were monitored quarterly For water levels and field parameters if they were discharging. No <br />
