The Golden Eagle Mine has had only limited mine <br />development. However, mine development has occurred under <br />windmill No. 6. The water level (while pumping) in this well was • <br />46.5 feet below the surface. The fact that the mill is still <br />functioning and no apparent seepage is occurring in the mane at <br />this location indicates the development mining has not impacted <br />this well. Additional mining at the Golden Eagle near the <br />Purga.toire River will not impact any domestic water users because <br />they are on city water. Well 15 is apparently spring fed and <br />well 16 is probably completed in an upper coal seam. Mining the <br />Maxwell and Allen Seams 200 to 300 feet below these wells should <br />not result in any significant impact. <br />Water, Waste and Land performed a hydrologic analyses on <br />bedrock and alluvial aquifers in the vicinity of the Golden Eagle <br />and New Elk Mines. In this analyses, the effects of mining on <br />these aquifers were estimated. It was determined that mining <br />will have no impact on the alluvial aquifer system. Therefore, <br />the shallow wells identified in this survey along with the <br />Purgatoire River will not be impacted. ~~ <br />Since the highland windmills are believed to be tapping <br />water in the upper coal seams and not the Maxwell Seam, mining <br />should not impact these wells. Although the Golden Eagle has not <br />been longwall mined to date, the empirical data from the New Elk <br />indicates subsidence effects should be similar. The geologic <br />structure is basically the same and the depth to coal is <br />consistent with the New Elk. This combined with all previous <br />studies and commitments insures protection of the hydrologic <br />balance. <br />Lastly and most important, no water users were identified <br />which utilize the Maxwell Seam as a groundwater source. <br />2.04-16 (Revised 09/01/89) <br />
