EXHIBIT D - Mining Plan <br /> The original mining plan will not change. It is repeated here as in the original application. <br /> Any changes are noted in bold. The amendment is adding all the area north of the existing <br /> permit in Section 31. It is labeled as area 7. Each mining phase will be staked as a new <br /> area is opened. Each of the original five tracts are expected to extend northward into the <br /> amended area labeled 7. Tract 6 will remain the same size. <br /> a) Mining will utilize the following operations: <br /> i)Use of dozer to remove and stockpile existing top soil <br /> ii)Utilize dozer to remove and stockpile overburden <br /> iii) Utilize dozer to push up gravel <br /> iv) Utilize a frontend loader or track hoe to load material onto trucks. <br /> b) The site will be mined to approximately 10 feet deep in the creek area and up to 20 <br /> feet if mining goes into the adjoining banks. Mining will be done on an approximate <br /> 3:1 slope down to the bottom of the pit area. There is no topsoil in the actual dry <br /> creekbed itself. Topsoil outside the creek bed ranges from 4"-5"in depth. The area <br /> lying outside the creek bed will have the topsoil stripped, stockpiled for re-application <br /> during reclamation. The bank along the creek will also be stripped and stockpiled for <br /> later use in reclamation. Any topsoil stockpile will be seeded with brome grass to <br /> prevent soil erosion. <br /> c) There are no anticipated water diversions or impoundments. There is no surface <br /> water at the site. When rainfall occurs,the pit area may be unworkable for a few <br /> days. Since the use of the pit is intermittent,we will be able to work around those <br /> occurrences. <br /> d) Our intent is to work approximately 8-9 acres during each of the six mining phases, <br /> starting in the east and moving west over approximately 10 years. We plan to <br /> maintain a 25-foot setback around the entire perimeter of the pit for maintenance and <br /> inspection. There will be a 200 foot buffer along the west edge and 130 foot buffer <br /> along the north and east edges of the pit. No mining will occur within 200 feet of <br /> the pipeline. Only 76.4 acres will actually be disturbed. The boundary line and <br /> corners of the open areas will be clearly staked with red painted steel posts <br /> e) The mining plan is to begin in the east area(currently in production). We will <br /> remove top soil by dozer and create a stockpile on the west side of this 10-acre area. <br /> The top soil on the west edge appears to be about 3"-6"deep, while top soil along the <br />
