• (Exhibit 27) will prevent any pollutant fron affected or impacting the <br />adjacent alluvial valley floor. The effect of mining on the hydrologic <br />function of the alluvial valley floor associated with the Purgatoire River <br />is addressed specifically in Exhibit 8, Hydrology and Geology Information. <br />WFC has extenstively mined the Allen Seam at the New Elk Mine beneath the <br />existing alluvial valley floor. During the mine's operation since 1952 <br />significant and extensive portions of the Allen Seam have been removed to <br />maximize the coal recovery of the area. Results of the study by Water, <br />Waste and Land, Ltd. indicate that even though large proportions of the in- <br />place coal has been removed by mining, little or no effect of the <br />hydrologic functions of the alluvial floor is evident. In fact, no effects <br />of subsidence, if any, have been located at the New Elk Mine. <br />The operation of the New Elk Mine, as described in Section 2.05.3, <br />is specifically "grandfathered" by existing Colorado Regulations for Coal <br />Mining in or adjacent to alluvial valley floors. Since the New Elk Mine <br />was constructed prior to 1952 and has been operating continuously since <br />that date, permission to mine this area has been previously granted. In <br />fact, the New Elk Mine has been in operation since times prior to the <br />implementation of the Las Animas County zoning regulations. The mine's <br />location within and adjacent to the alluvial valley floor was prior to <br />August 3, 1977 and produced coal in comrercial quantities in the year <br />preceeding August, 1977. Exhibit 5, Las Animas County Correspondence, <br />shows that the New Elk Mine has been in operation prior to Ias Animas <br />County Zoning Regulations. <br />2.06.9 eri <br />WFC does not plan to utilize angering at the New Elk Mine. <br />• 2.06-3 <br />
