early years of Edna Mine, the high BTU Lennox coal was selectively removed <br />• for the stoker coal market. As a result, portions of this seam still <br />existed even though the overburden may have been stripped above the seam at <br />one time. The Wadge coal seam was the most extensive seam in this area and <br />has been mined over most of the area at Edna Mine. Small portions of the <br />Lower Wadge seam have been mined in recent years. Exhibit 3.1-2 designates <br />the coal seams mined, and the areas and dates of past mining. <br />The land uses that preceded mining especially on West Ridge are <br />unknown. Exhibit 3.1-2 shows the disturbance that occurred before the <br />enactment of reclamation laws, the disturbance that occurred under the two <br />Colorado Reclamation Laws, and disturbance under the phases of the OSM <br />Surface Mining Control and Reclamation Act. The areas shown on Exhibit <br />3.1-2 indicate man-made disturbances in and around the permit area for <br />roads, powerlines, buildings, beltlines and mining. <br />3.1.2 PRESENT AND FUTURE MINSNG <br />3.1.2.1 Mine Reserves and Production <br /> No additional mining will occur under this permit term. The mine has <br />• been placed in permanent closure and only reclamation activities remain to <br /> be performed. <br /> Bonding costs have been determined in accordance with this mining <br /> sequence that took place and may be found in the bonding section, 9.8 of <br /> this permit. <br />3.1.2.2 Affected Areas <br />All acreage designated to be affected at the Edna Mine has occurred and is <br />undergoing final reclamation. The acreage affected by mining activities at <br />the Edna Mine is shown on Exhibit 3.1-3. <br />Exhibit 3.1-3 shows all areas affected by mining under this permit <br />including topsoil and overburden removal in addition to roads, powerlines <br />sediment ponds, support facilities and stockpile areas. The following <br />table summarizes the acreage information of Exhibit 3.1-3. <br />• <br />Renewal-3 3.1-2 June 13, 1997 <br />
