Exhibit D MINING PLAN Unless specifically discussed below the methods described in the Conversion amendment approved in 1996 mining and reclamation plans will remain unchanged. The current bond is $20,300 and a new reclamation cost estimate is presented in Exhibit L on page 15 of this application. Existing sloping, grading and shaping plans will apply to the new area since they are similar to the area now in the permit. The following changes to the mining plan are numbered sequentially to give some order to this amendment. A GEOTECHNICAL STABILITY EXHIBIT is included to describe how mining next to the structures around the mine will be handled. AMENDMENT 1 - Acreage added to Permft This section describes the changes in area made to the permit. This amendment adds 71.37 acres to the permit area that adjoins the existing permit area on the south. It abuts the existing permit area on the east, west and south sides. We have created three new maps that show the entire permit area. The green outline is the new area and the yellow outline is the existing permit area. The Pre-Mining (Existing Conditions) Map shows approximately how the site looks now. The Mining Plan Map showing how we feel, the site will look when mining pro- gresses into the new area and the direction of mining. There will still be areas in the existing permit area that will need to be mined to total depth. The Reclamation Plan Map shows how McAtee thinks the site will look when mining is complete. Note that the existing area looks like the maps currently on file, with the exception that the west and south slopes have been removed and the two areas are blended creating a larger floor area. Mining will begin on the new area once this amendment is approved, using the methods described in the 1996 conversion and amendment Mining Plan. All setbacks around the site in the new area will be 10 feet from the permit line to the dig line, except along the county road and along the powerline where a 25 foot setback will be maintained. This area will provide access around the mined area. The rational for the setbacks are discussed in the 1996 amendment on page 9. According to the NRCS report in Exhibits i/J of the amend- ment starting on page 24(1996), there is very little topsoil on this area. it is possible that we can salvage enough to place 4 inches on the seedbed areas. When topsoil or growth medium is encountered it will be stored on the setback areas or the mine floor for use in reclamation. If the stockpiles remain undis- turbed for more that a year the piles will be, seeded with 3 pounds PLS of western Wheatgrass per 200 square feet to prevent erosion. The growth medium piles will be kept within 500 feet of the seedbed to reduce the haul distance to its final location during reclamation. As mining progresses thru the site and additional stripping has to be done the material will either be stockpiled for later use or moved directly to the areas needing recoiling. 3
