In order to gain an understanding of the extent of the mining operation, it is helpful to know the <br /> acres disturbed by different aspects of the mining operation. Each aspect is listed in the <br /> following table with associated disturbed area. The table illustrates a point in time where the <br /> mining disturbance could be at its maximum. At the proposed Lazy Two Pit site, it is assumed <br /> that the mining disturbance will be at its greatest close to midway through the mining operation. <br /> During this scenario, the southern portion of the site has been mined and the pit is partially <br /> backfilled to establish final site drainage. Only about half of the required backfilling, grading, <br /> and revegetation of the pit has been completed at this point. To complete the backfilling, <br /> material from un-mined areas of the site will need to be harvested, placed in the pit, graded, <br /> topsoiled, and revegetated. Additionally, highwalls associated with the active mining face and <br /> approximately 500 feet of side slope on both sides of the mining face will require dozing, <br /> grading, topsoiling, and revegetation. <br /> Mine Operation Aspects and Disturbance Areas <br /> Mining Operation Disturbed <br /> Aspect Area (acres) <br /> Active Mining Area: <br /> 1. Near vertical active mining face and 100-foot wide <br /> A pre-stripped area in anticipation of mining. 13.8 <br /> 2. Near vertical un-reclaimed pit side slopes. <br /> 3. Un-reclaimed pit floor. <br /> Material Harvesting Area and Pit Backfilling <br /> 1. Material harvest area in un-mined area—78 acres. <br /> B 108.5 <br /> 2. Partially reclaimed pit, backfilled with harvested overburden <br /> material to grade— 30.5 acres. <br /> Miscellaneous Disturbed Areas: <br /> 1. Scale house building area. <br /> C 2. Internal haul roads. 2.0 <br /> 3. Main site access road. <br /> Final Reclamation: <br /> D 1. Seeding. NA <br /> 2. Re-seedin . <br /> Total Disturbed Area 124.3 <br /> Diversions and Impoundments <br /> The existing grade of the proposed permit area generally drains from north to south. Stormwater <br /> that falls directly on disturbed areas will generally drain to the mine pit and allowed to infiltrate. <br /> The active mine pit will effectively contain stormwater flows and prevent surface runoff from <br /> disturbed areas of the site. Stormwater not encountering disturbed areas will be allowed to drain <br /> within natural drainage patterns. <br /> Lazy Two Pit <br /> DBMS 112 Permit Application Page 8 <br />
