EXHIBIT D - Mining Plan <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. Thus, only 52.9 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 />east side is almost non - existent. Stockpiles of top soil will be seeded with brome <br />grass to minimize blowing or erosion. When area number one is mined, the top soil <br />will be spread out evenly and the 3:1 slope maintained on the sidewalls. Area 1 will <br />then be seeded according to the reclamation plan. The next area to be mined will be <br />to the west of area one. Areas 2 through 6 lie immediately west of area 1 in <br />consecutive order. That area lying 200' on each side of the existing natural gas <br />pipeline will not be disturbed. <br />No on -site processing is anticipated. <br />
