MINING PLAN EXHIBIT D (CONT) <br />3 to 25o slope. See the soils map in the NRCS report for how the <br />soils are distributed on the permit area. More detail informa- <br />tion including, the soils description and engineering qualities, <br />can be found starting on page 28 in this application. <br />Based on the soils report and on site observations there are <br />sufficient quantities of soil available to reclaim the disturbed <br />lands to their present condition. The soils in this area may <br />not be of the highest quality, but when salvaged and replaced <br />should be capable of growing vegetation consistent with what is <br />there now. The average depth of topsoil on the site according to <br />the NRCS report is 0 to 7 inches deep. Using 5.0 inches as the <br />average we calculate there should be 15,360 YD3 of growth medium <br />available for resoiling the disturbed area. In addition, there <br />is from 4 inches to 5 feet of overburden on most of the site. <br />Much of this overburden will be retained and used to rebuild <br />slopes or create root zone under the seedbed. If needed, it <br />could be transformed into growth medium to supplement topsoil <br />needs. Be assured we will retain enough growth medium on the <br />site to assure reclamation and revegetation is successful. The <br />topsoil and overburden stockpiles will be located around the <br />excavation (their approximate locations are shown on the MINING <br />PLAN MAP) to reduce the haul distances when reclamation starts. <br />If the soil stockpiles remain undisturbed for more than one year <br />a cover crop of Western Wheatgrass at a rate of 2 pounds -pls /100 <br />sq -ft will be planted on them. <br />MINING PLAN <br />Of the 26.73 acres ± in the permit area a maximum of 25.22 <br />acres ± will be disturbed by the mining operation. Presented in <br />this mining plan are detail plans for developing the mine under <br />3 different options. The first will be to create slopes around <br />the site as shown on the EXHIBIT F -1 - RECLAMATION PLAN MAP. The <br />second would be to mine thru the property line on the east side <br />to join the floor with of this mine to the neighboring mine, <br />shown on the EXHIBIT F -2 - RECLAMATION PLAN MAP. This leaves a flat <br />area with no ridgeline and is preferred by Mr. Hribar who owns <br />the property. The third would be to mine thru the west property <br />line so there is no ridge between this mine and the Ted <br />Franciscotti Pit #1 as shown on the EXHIBIT F -3 - RECLAMATION PLAN MAP. <br />L-11 <br />
