EXHIBIT D - Mining Plan <br />a) Mining will utilize the following operations: <br />i) Use of scraper to remove and stockpile existing top soil <br />ii) Utilize scraper to remove and stockpile overburden <br />iii) Utilize dozer to push up gravel <br />iv) Utilize a frontend loader to load material onto trucks. <br />b) The site will be mined to approximately 45 feet deep. Mining will be done on <br />an approximate 3:1 slope down to the bottom of the pit area. Topsoil ranges <br />from 5" in depth to 10" in depth at the southeast corner. The topsoil will be <br />stripped, stockpiled, and utilized when the pit is reclaimed. <br />c) There are no anticipated water diversions or impoundments. There is no <br />surface water, at the site. When rainfall occurs, the pit area may be <br />unworkable for a few days. Since the use of the pit is intermittent, we will be <br />able to work around those occurrences. <br />d) Our intent is to work approximately 13 acres during each of the three mining <br />phases. When the 225' outside buffers and 200' buffer around the windmill <br />are taken out, there will be approximately 40.8 acres which is actually mined. <br />e) The mining plan is to begin in the area of the soils map listed as soil 26 or <br />Laird fine sandy loam. This runs from southeast to northwest across the <br />eastern portion of the pit. We will remove top soil by scraper and create a <br />stockpile on the southwest slope of the Valent sand on the northeast corner of <br />the area. We will treat the top one foot as top soil as this layer is where roots <br />and vegetation are the most abundant. Stockpiles of top soil and overburden <br />will be seeded with crested wheat grass to minimize blowing or erosion. The <br />next step will, to remove the next two feet of light grey very fine sandy loam <br />(overburden) with the scraper and stockpile west of the topsoil. NCRS <br />recommendations are not to mix the two layers because of an abundance of <br />alkaline in the overburden. The next material which will be utilizing for road <br />beds has a magnesium and calcium content When area number one is mined, <br />the overburden will be spread out and the 3:1 slope maintained on the <br />sidewalls. Topsoil will then by hauled by scraper onto the freshly placed <br />overburden. Area one will then be seeded according to the reclamation plan. <br />The next 10 acre area to be mined will be to the west of area one. The third <br />area will lie immediately west of area 3. <br />i) Since the pit will be used on an intermittent basis, it is difficult to <br />estimate the time it will take to mine all three areas. We are estimating <br />that it will take ten years to mine the pit. <br />ii) Area one will be approx. 10 acres and is located on the eastern portion <br />of the pit. Area 2 will be 10 acres and is located west of area number one
