• • ~ '? <br />(9) ~ ~~ ~~ <br />l <br />3. Mine Spoil Dump Areas, PLate 1, will be placed in fou~ <br />stages of compacted lifts*. Upon completion of each o~ these lifts <br />the face of the slope (2.5:1) will be covered with 12" of <br />topsoil. The soil will receive amendments as appropriate and will <br />be seeded with mixture No. 3. Upon completion of the seeding, <br />excelsior erosion blankets will be laid. When the ground cover <br />has established native vegetation will be planted on the slopes. <br />Benches between lifts will be topsoiled and seeded in the same <br />manner. Here a hydro-mulch will be used to hold the seed and <br />moisture until establishment of the ground cover. Native <br />plants will then be added. The entire area of the Mine 6poi1 <br />Dump will be a wildlife habitat area. <br />4.

Coal Storage and Parking Area, Plate 1, will be covered <br />with approximately 12" of sub-soil and 6" of topsoil. The final <br />configuration of the landscape on the benches will be relatively <br />flat. Soil amendments will be added and the areas will be seeded <br />with mixture No. 2. Hydro-mulching with wood cellulose fibers will <br />then be accomplished. Some native vegetation will be added upon <br />establishment of the grass. This area will be used for grazing and <br />incidental wildlife habitat. <br />*It should be noted that the Mine Waste Dump areas depicted <br />on Plate i show projected areas for future mining as well as that <br />area which will be disturbed during the three year period of the <br />mine plan. ~ ~ <br />d <br />II i <br />Ipl,p I <br />~Ull~lhi~~l~' 11 ~~i~~~if y. <br /> <br />
