Appendix, Volume 4). The applicant has installed a production well and curcently uses this water for domestic use, dust control, and fire control. The recharge to the Steven's Gulch well field area is through flow from the adjacent colluvial deposits and from a leaky pipeline aqueduct. The ground water flows through the colluvium downslope to the alluvium, where it becomes trapped or temporarily stored. This situation is somewhat modified by the presence of landslide complexes which occur throughout the general area in the Bowie and five adjoining quadrangles (Colorado Geological Survey Information Series 5, 34p.). Ground water will tend to move down through the more permeable material and along lateral shears of these landslide complexes. The sources of ground water discharges from the Steven's Gulch alluvium at the well field are through the applicant's wells, through underflow within the alluvium down the old bedrock channel of Steven's Gulch, and through discharges to the stream during high water table conditions in spring and early summer. Water quality analysis for the Steven's Gulch well water indicates good quality water, with none of the parameters exceeding the recommended standards of the Colorado Department of Public Health and the Environment. AlluviaUcolluvial deposits in the Terror Creek drainage near the Morrell Cow Camp are also being utilized for water supply purposes. However, no impact is predicted for these areas since lands affected by mining lie to the south and east. Occurrences of ground water have been noted in the Mesaverde Formation from information obtained from drilling, experience in the mine and from the presence of springs and seeps in the permit area and hydrologically adjacent area. This information indicates that the only potential regional aquifer in the area is the continuous Rollins Sandstone, located stratigraphically approximately 200 feet below the D coal seam. Recharge to the Rollins Sandstone occurs along outcrops and along subcrops beneath the alluvium of Terror Creek to the east and Steven's Gulch to the southwest. However, due to the steepness of the topography in the outcrop areas (i.e. sandstones are cliff formers) and the narrowness of the stream valleys, the Rollins Sandstone receives little recharge. Some recharge to this continuous unit may come directly from the percolation of snowmelt and precipitation downward through fractures. While no site=specific aquifer characteristics for this unit are available from the permit area, indications aze that saturated portions of the Mesaverde Formation are not good aquifers (pages 33 to 37, Section 2.04.7, Volume 1). Ground water occurrences in the stratigraphic interval of the Mesaverde Formation above the D seam are a function of the depositional environment and are characterized by saturated horizons of localized lateral and vertical extent, separated by low porosity, unsaturated intervals. These saturated horizons do not appear to contribute significantly to overall regional ground water flow. To date, the Bowie No. 1 Mine has experienced maximum inflows of around 1,500 gpd. This inflow came from both the floor and roof and were generally roof drips or wet areas on the floor. Mining progressed below East Roatcap Creek and mine inflows have increased but still remained insignificant to the local hydrologic regime. The portals of the East Mine were sealed in 2001 and the portals at the West Mine were sealed in 2000, so no recent mine inflow information is available. Inflows from faults and fractures located outside stream valleys (such as in the Bowie No. 1 Mine) generally dry up with time or flow intermittently at discrete points along the fault or fracture. Those which continue to flow have flow rates which diminish to a trickle. Such inflows may represent the dewatering of lenticular sandstone units with limited recharge areas, or may represent flows through fracture zones extending to the surface which have narrow recharge zones on steep slopes. 13
