Additional comments on <br />the remaining aspects of the application will be forthcoming in the <br />near future. The comments contained in this letter are in addition <br />to those raised in the Division's April 23, 1981 preliminary adequacy <br />review dated December 5, 1980. We will look forward to receiving your <br />responses to each of the following items. <br />Geology - 2.04.6(2) <br />The site geology map and cross-sections (Plate 8 and 9) provided within <br />the permit application are both illegible and at inappropriate scales. <br />The site-specific geology should be resubmitted on a legible, large <br />contour map with the mine plan area and permit area clearly drawn. <br />This map should include the strikes and dips of beds; the crop line of <br />the coals; any faults, fractures, landslide bodies; contacts of all <br />geological units including. alluvium and colluvium; the location of all <br />drill holes; and the location of the cross-sections. Two new large- <br />scale geologic cross-sections should be submitted: One along the dip <br />of the coal beds, and one along the strike of the coal beds. These <br />cross-sections should, at a minimum, cover the permit and adjacent areas <br />for this permit period (5 years). Legible lithologic logs and geophysical <br />logs should be submitted for the permit and adjacent areas (e.g., those <br />used in the construction of the geologic map and cross-sections). <br />_, ~ i <br />
