OVEM Groundwater Monitoring Wells: • Groundwater monitoring wells B01, B02, and B04 through BOS are near the East Mine facilities (see Map No. 8-I). Well B07 did not have adequate water to monitored for annual water quality parameters. Wells BO1 waz destroyed by the reclamation project during 2003. Wells B02, B04 through B06 and Well B08 are monitored semi-annually for water levels to assess slope stability in and around the East mine facilities. Patterns typically associated with these wells in the past were again evident during the 2003 monitoring yeaz. B03 is blocked and can no longer be monitored for field parameters or water quality, it has been removed from the sampling regime by TR-34. Wells B02, BOS, B06 and B08 remained dry to damp throughout the year. Well B04 showed moderate water level fluctuations within the established normal ranges previously documented. Conductivity values at B07 remained within the range of values previously established. Other monitored parameters fluctuated slightly with established ranges. OVWM Groundwater Monitoring Wells: One piezometer (OV WM) was installed in the fill at the Orchard Valley West Mine. This well was destroyed during mine reclamation and is no longer monitored. North Fork Alluvium Groundwater Monitoring Wells: Three (3) wells, MW-1, MW-2 and MW-3 (see Map No. 8-3) are completed in the North Fork of the Gunnison alluvium. Dwing 2003 the wells were monitored monthly for water levels and showed typical seasonal fluctuations within previously established ranges. MW-1 and MW-3 were monitored quarterly for quality dwing 2003 to monitor potential groundwater effects stemming from the coal stockpile and load out facilities in the North Fork Valley. Well MW-1 is east of the load-out in an area that should be outside or above the area of influence of the coal stockpile and loadout area. Well MW-3 is southwest of the coal stockpile azea in a location that should see the full impact of any potential groundwater degradation. The 2003 data continues to show that the stockpile and load-out are not degading the water in the alluvium. East Roatcap Creek Colluvium Groundwater Monitoring Wells: Shallow groundwater monitoring wells, SM-5, SM-6, SM-7, SM-10 and SM-11 (see Map No. 4-1) are in the East Roatcap Creek drainage. The wells were monitored for water quality parameters, water levels, and Feld parameters to detect impacts associated with mining in the west pod. All of the wells were monitored semi-annually for water levels, field pazameters and water quality. SM-7 is within the projected angle-of--draw of mine workings. Water levels from the five Roatcap Creek colluvial wells continuedto showtypical seasonal variabilitywith water levels elevated in the spring and lower at the end of the year. No anomalies or impacts on water levels were observed in 2003 at these wells. Steven's Gulch Colluvium Groundwater Monitoring Wells: Shallow groundwater monitoring wells, SM-] and SM-9 (see Map No. 4-1) aze in the Steven's Gulch drainage. The wells are monitored for water quality parameters, water levels, and field parameters to detect impacts associated with mining in the central pod. Required monitoring for wells SM-1 and SM-9 was semi-annually during 2003 for water levels and field parameters. Well SM-1 is next to azeas mined in 1991 and 1992 but showed no apparent impacts in the field data collected dwing 2003. Well SM-9 was undermined by Panel C during 1993 but showed no apparent impacts in the field data collected dwing 2003. No anomalous water quality observations were apparent dwing 2003 at the Steven's Gulch shallow groundwater monitoring wells. Surface Water Monitoring Stations -SPRINGS East Roatcap Creek -Two springs were monitored in the East Roatcap Creek drainage (refer to Table 1 and Map No. 4-1) during 2003. Spring 30 had sufficient water for field parameters but no flow in May and found dry damp dwing the remainder of the year. Spring 30 waz first undermined iti Apri1,1983. Spring 10-10 waz dry the reporting period. Spring ] 0-] 0 waz encompassed by the angle-of--draw of Panel Y dwing October, 1993. Subsidence impacts were not apparent at either of these locations dwing 2003.
