Page 2 of 3 <br /> 6. Two phases are delineated on Exhibit C. The exhibit was revised as follows: <br /> Two phases are delineated on Exhibit C. The Division will be notified of subsequent <br /> phases within the Affected Area Boundary by submission of a Technical Revision. <br /> 7. Mining will not occur within the natural ravine cut by historic surface drainage. The target <br /> sandstone outcrop, however, is immediately adjacent to the ravine. The exhibit was revised <br /> as follows: <br /> Mining will not occur within any ravines but the sandstone outcrop, the target <br /> reserve, is adjacent to the ravine. During substantial precipitation events,the ravine <br /> stormwater flow may spill onto the target outcrop. <br /> An armored stormwater diversion channel will convey surface flow to the south <br /> infiltration pond near the natural ravine should the mine floor elevation become <br /> lower than the stream bed elevation. <br /> 8. As stated in the third sentence of paragraph 3, KrauthCo will post bond by phase. The first <br /> phase is proposed for 15 acres. <br /> 6.4.5. Exhibit E—Reclamation Plan <br /> 9. The permit boundary does NOT include open space public lands. The exhibit was revised as <br /> follows: <br /> The mine boundary includes bedrock outcrops, rocky terrain and isolated areas of <br /> rangeland. <br /> 10. The requested cross-section detail is provided as Figures F-2 and F-4. The maximum <br /> proposed gauge for the highwall is 10 feet vertical and 8 feet horizontal. The deposit <br /> naturally breaks in eight to 12 inch lifts. The final highwall will likely be an average of one <br /> foot vertical with one to two feet horizontal benches. The north to south outcrop grade is <br /> 18% and the east to west outcrop grade is 13%, allowing storm water to drain out of the <br /> benches. The pit floor will have a final grade of 4%,draining toward the ravine.The direction <br /> of drainage is represented with blue arrows on Figure F-3. <br /> 11. The topsoil will not be compacted. The exhibit was revised as follows: <br /> Any salvaged sediment or plant growth material will be stockpiled for use in final <br /> reclamation when it will be mixed with rock fines, placed on the exposed surface to a <br /> depth of six to eight inches. <br />
