Mr. Connor Drinkard <br /> RE: Carr Pit East M-2022-005 <br /> June 27, 2022 <br /> and graded, the area is seeded as soon as is practical to stabilize the material from wind and <br /> stormwater erosion. <br /> Despite our believe in the rapid concurrent reclamation process, we have reassessed the <br /> disturbance table in Exhibit D —Mining Plan and feel that additional area should be added to <br /> account for seeded, but not completely reclaimed acreage. Although we do not believe this <br /> would include all of Phase I, the area of Phase I that has already been backfilled, graded, and <br /> seeded (outside of the active and partially reclaimed areas) may require additional <br /> reclamation action if seed growth is disturbed by drought, bison and antelope grazing, etc. <br /> Reseeding typically involves 20 percent of the originally seeded area. The below revisions <br /> for the Mining Plan table will be reflected in revisions to Exhibit L—Reclamation Costs. <br /> Revised 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 (1,000 linear feet). <br /> 2. Pre-stripped area in anticipation of mining <br /> A (1,000 feet by 100 feet= 2.3 acres). 13.8 <br /> 3. Near vertical un-reclaimed pit side slopes (500 linear feet on <br /> each side of mining face). <br /> 4. Un-reclaimed pit floor(11.5 acres). <br /> Partially Reclaimed Mining Area: <br /> B 1. Pit side slopes (2,000 linear feet) dozed/backfilled to 3H:1 V. 12.5 <br /> 2. Partially reclaimed pit floor. <br /> Previously Mined and Reclaimed Area: <br /> C 1. Previously seeded (74.4 acres) 14.9 <br /> 2. Re-seeding (20% of previously seeded area) <br /> Miscellaneous Disturbed Areas: <br /> D 1. Internal haul roads. 2.0 <br /> 2. Main access road to Connell Carr Pit(M-2014-001). <br /> 3. Other areas disturbed by mining activities. <br /> Final Reclamation: <br /> E 1. Seeding. NA <br /> 2.
