• 3. The active et rip mined pit has had minimal pit pumping, therefore we are anticipating <br />very small quantities of additional discharge caused by the auger operations. Any <br />necessary pit dewatering activities will follow the procedures described in Tab 13 on <br />page 6 in paragraph 1. <br />4. The premising ground water flow should reestablish itself following backf filling of the <br />final pit areas which have been augered. <br />Surface Watet <br />Surface water quantity and quality should not be affected by the auger mining operation <br />since drainage will be handled in the same manner as existing final highwall stripping <br />conditions. The poatmining reclaimed surface will be blended with the surrounding spoils <br />and topography. The surface will be revegetated in accordance with the approved <br />revegetation plan. Should subsidence occur, surface drainage will not be adversely affected <br />as no poatmining drainages will course over the proposed auger mining areas. <br />Ownership <br />The surface and coal is owned by different entities but SCC holds coal leases on.those areas <br />• proposed to be augered. Refer to Exhibit 3-1 in Tab 3 of the permit application package for <br />any details. <br />Operation Plan <br />SCC is proposing to auger the wadge coal seam as shown on Exhibit 12-1, Sheet 2 of 2. <br />Angering at Yoast will start at bottom of the neck pit area final highwall and progress to <br />the south. As stated earlier, SCC will auger the entire length of the final highwall. The <br />equipment to be utilized for the auger mining operation will be: <br />1. Brydet Model 2348-72 Coal Recovery Auger <br />2. Brydet Model B-775 Crawler Mounted Elevating Conveyor <br />3. Caterpillar 988 Wheel Front-End Loader <br />Auger Mining Plan <br /> 1. The area will be surface mined according to the approved, existing mine plans. <br /> 2. After overburden and coal removal is completed, some highwalls and endwalls will be <br /> auger mined, see Exhibit 12-1, Sheet 2 of 2. It should be noted that the area as shown <br /> on Exhibit 12-1, Sheet 2 of 2, is the projected final highwall location, and angering <br />• areas will vary based on the exact final highwall locations and associated mining <br /> conditions. <br />12-1-3 Revised O1/O1 <br />
