z-1 <br />2.1 GENERAL DESCRIl'TION OF MINING OPERATION <br />The operation will extract coal from the Cameo Coat Seam in portions of the proposed permit area <br />as shown in Figure 2.1-I . The operation is conducted from a bench excavated at this coal outcrop. <br />Activities are conducted underground as described in Section 2.1.5 and shown in Figure 2.1-2. The <br />excavated bench area (1.42 acres) is designed for support activities and facilities, see Figure 2.2-2. The <br />mine plan details the mining proposed for this permit term as well as addressing life of mine projections for <br />the entire permit area. <br />The bench area and access was originally approved through a joint on site inspection by the USGS, <br />BLM and Company representatives. All facilities and structures aze confined to the disturbed and proposed <br />disturbed area. The initial bench excavation and access road construction that were originally approved by <br />the USGS and BLM constitute a major portion of the overall disturbance. Additional area in the vicinity of <br />the canyon mouth was approved for use for ancillary facilities such as sedimentation control structures, see <br />Figure 2.2-2, Additional future disturbance includes construction of a road to connect Munger Canyon and <br />McClane Canyon, see Section 2.2.2 and Figure 2.2-4. If additional facilities aze necessary, they wiil be <br />constructed only after modification and approval of this permit. <br />Coal waste may be generated from the operation in the form of coal fines and other material (high- <br />ash coaly material) scraped up from the coal yard azea. This material will be stored at the temporary pile <br />adjacent to the coal product stockpile. The temporary pile will not exceed its current volume which is <br />approximately ],350 cubic yards (1000 tons). This material will be blended and shipped with the product <br />when possible. A plan for permanent disposal, off site, of high-ash coaly material is currently being <br />formulated and will be handled as a technical revision. The technical revision addressing all applicable <br />provisions of 2.05.3(8), and 4.10 will be submitted no later than June 1, 2001. The operator has also <br />obtained approval from the Mine Safety and Health Administration (MSHA) to dispose of non coal rock <br />slope material in areas of the mine that aze no longer actively producing coal. <br />McClane Volume I November 30, 2001 <br />
