be graded and smoothed over, topsoil redistributed and readied for re- <br />vegetation. See attached diagrams. <br />• <br />(F) Grading and Backfilling. After the surface facilities have <br />been dismantled and removed, the top layers (from zero to twelve inches) of <br />coal, shale, sandstone and other soils, will be scraped and graded into a <br />pil,_ for backfilling the mine portals. Those materials which are not suit- <br />able for reseeding can best be handled by its removal off the mine bench <br />rather than burying the pile under amended topsoil. <br />After the portals are backfilled and sealed, the disturbed <br />areas will be backfilled and topsoiled to approximate the original 3:1 slope. <br />Since the permitted areas affected are less than 4.1 acres, including the <br />access roads, a foreign but acceptable topsoil material will be acquired <br />from one of several sand and gravel producers in the area. 4410 cubic yards <br />will be imported as calculated by Peter O'Connor. Topsoil will be analyzed <br />to determine compatability. <br />• (G) Topsoil Disbursement and Gradinq. Coverage of the permit <br />area with new topsoils for reseeding and plant growth will be as follows: <br />Location Soil Depths <br />3:1 slopes 4-8 inches <br />(H) nevegetation. Development of a vigorous grass dominated veg- <br />etation cover of predominantly natives, including some shrubs ar.d will re- <br />store the general character of the vegetation to that found in the mine plan <br />area. The projected relatively open vegetation •~ill increase structural <br />diversity in the immediate vicinity and probably will enhance the suitability <br />of the area as wildlife habitat. Grazing will be prevented in the reclaimed <br />area until it teas been demonstrated to the satisfaction of file Division that <br />vegetation on the reclaimed surface is adequately established and could be <br />expected to withstand grazing. A vigorous plant cover will protect soil from <br />erosion, maintain surface water quality, and minimize degradation of air <br />quality due to fugitive dust. Species of shrub, forbes, grass and grass- <br />like vegetation will be used in the re vegetation phase of reclamation. The <br />• plan has been developed with consideration of elevation, soils, slope, ex- <br />posure, and local climate. Noxious weeds, should they appear in the amounts <br />
