No requirements were placed upon l;nergy Fuels to conduct tests on overburden to determine the acid-forminc, or toxic-producing proi>erties.. However, subsequent tests have been conducted in adjacent strata through the same geolocic strata. Results of these analyses reveal no acid or toxic- prodticing agents present in any of the strata examined. 2. Topsoiling A brief description has already been given on how the topsoi]. was salvaged prior to stripping of the coal. Topsoil c•:as reapplied usitiy tractors with the topsoil bei:z, pushed uj~hill until a uniform t}~ic}:Hess was achieved. S_nce the spoil grading was done with cra~,aler tractors, a fair l}' rough boundary existed between the topsoil and the leveler spoil. The approximate depth of surface and subsurface topsoil that was applied was two feet, with topsoil in sc-ie depressions on the area being deposited to a greater dept::, The topsoil was stockpiled approximately 18 months prior to reapplication. The soil series covering this sire prior to mi^ing has been identified as a 5uckley Silty Clay Loam. According to the Soil Survey Interpretations obtained from the Soil Conservation Service, this soil is unsuited for use as a topsoil. Potential uses for reseeding are classi`_ied as poor to very poor primarily due to the high clay content. Soils with such high percentages of clays commonly have Zcw permeability rates, high shrink-swell potentials and ren~er seedlings vulnerable to mortality due to the frost-heavi^g action of the soils. Final leveling of the topsoil was done by a motorgrader to achieve a uniform seedbed prior to reseeding. 3. Revegetation Following the leveling of the topsoil, the area was seeded with a mixture recommended by the Soil Conser:•- ation Service. The mixture that was recommended to Enercy Fuels was: Seed Mixture Species ...
