The remaining Phase 2 area has been backfilled, compacted, graded, and stabilized with the <br /> previously approved grass seed mix. <br /> Although Phase 3 is actively being mined, the area is relatively small compared to the Phase 1 <br /> mining disturbances yet to be reclaimed. As Phase 3 is mined, it is continually being partially <br /> backfilled for stabilization. However, to calculate maximum mining disturbance it is assumed <br /> that most of Phase 3 will require completed backfill, compaction, grading, and stabilization. <br /> Mine Operation Aspects and Disturbance Areas <br /> Disturbed <br /> Aspect Mining Operation Area (acres) <br /> PHASE 1 —Mining Complete <br /> Al Mined area(material processing area for backfilling, compacting, 11.1 <br /> grading, and stabilization) <br /> A2 Mined area(material processing area for reservoir liner 10.8 <br /> construction) <br /> A3 Mined area(previously backfilled material storage area for final 1.9 <br /> backfilling, compacting, grading, and stabilization) <br /> Mined area (previously reclaimed landscape/floodway diversion <br /> A4 berms; partial liner; below-grade reservoir bottom; recharge 55.4 <br /> ponds) <br /> PHASE 2—Mining Complete <br /> Weitzel Road right-of-way (6.3 acres previously reclaimed and <br /> released) <br /> B1 Mined area(previously backfilled, compacted, graded, seeded) 28.7 <br /> B2 Mined area(previously backfilled, compacted, graded, seeded) 14.1 <br /> PHASE 3—Active Mining <br /> Mined area(backfilled, compacted, stabilized for material and <br /> Cl 13.7 <br /> equipment storage, asphalt plant operation) <br /> C2 Active mining area (backfill, compact, grade, and stabilize) 5.7 <br /> C3 Mined area(previously backfilled active mine area for final 2.4 <br /> backfilling, compacting, grading, and stabilization) <br /> Total Disturbed Area 143.8 <br /> Commodities to be Mined and Intended Use <br /> Sand and gravel for use as construction materials are the primary products produced from the <br /> Timnath Connell Pit site. In addition to the commercial sand and gravel materials, clay, silt, and <br /> other non-marketable topsoil and overburden materials have been used on-site for reclamation. <br /> Use of Explosives <br /> Since the alluvial reserve is unconsolidated, no explosives or blasting is required. <br /> Timnath Connell Pit <br /> DRMS 112 Permit Amendment Application Page 9 <br />
