Ltr/Revw Bsln Env Data - 9 - July 2, 1986 <br />(E ). From the soil inventorying data, the applicant should be able <br />to determine topsoil volume summaries for each of the various soil map <br />units of the surface facility area similar to the volume calculations <br />present on Table 3.1-1 for the refuse area. Such calculations will <br />allow the applicant to determine concrete topsoiling values for <br />reclaimed areas and to determine if excess material is available for <br />the coal refuse area reclamation. <br />(F ). The applicant's July 1, 1985 response to the Division's PAR <br />concern pertaining to topsoil replacement as discussed on page 1 of <br />Section 2.05.4(2)(d) raises a number of concerns. <br />i. The applicant originally specified that topsoiling would occur <br />except when slopes were steeper than 2h:ly. The applicant's <br />July 1st response revised this to topsoiling slopes except those <br />steeper than 1.5h:1v. On these slopes steeper than 1.5h:1v, the <br />Division's original PAR concerns pertaining to chemical and <br />physical analysis of the projected plant medium is still required. <br />The medium should be analyzed per the suite identified in the <br />original PAR. <br />ii. The applicant specified slopes would be top soiled except the mine <br />bench outslopes because "It is not feasible to place topsoil over <br />this material (sandstone and shale rock)". Please specify why <br />topsoiling cannot occur. <br />iii. The map depicting all non-topsoiled areas as requested in the <br />Division's original PAR is still needed. <br />iv. If the Division concurs with the applicant's response to 6.B. <br />above, then the focus will switch back to the chemical and physical <br />nature of the material composing this slope. The Division agrees <br />with the applicant's response of "Since the mine bench outslopes <br />are not yet constructed, chemical and physical samples of the <br />material forming them is not particularly meaningful at this point <br />in time:. However, the Division's concern is still valid; <br />therefore, the applicant should commit to chemical and physical <br />analysis of the bench outslope material during construction and <br />submit these data and support text to the Division. Only after <br />receiving these actual data and report can the Division make a <br />valid determination pertaining to the need or lack of need to <br />topsoil this outslope area. <br />(G). The Division attempted to correlate the soils maps (Figure <br />2.04.9-1, four sheets) with the Fruita Mine Complex, Figure E-1. This <br />review was difficult at best due to the differences in scale (1" = 500 <br />feet (') for Figure 2.04.9-1 verses 1" = 2000' for Figure E-1) and due <br />to no section lines depicted on the soils map. This review did reveal <br />however, that there appears to be some areas depicted on Figure E-1 to <br />be disturbed (e. g., railroad spur corridor, Northern lease access road <br />corridor, southern portion of Tract 4) that were not sampled by the <br />intensive (Order 2) soil survey. The applicant should check the <br />accuracy of both of these figures and submit the additional soil <br />information if there are areas proposed to be disturbed but not <br />surveyed and depicted on Figure 2.04.9-1. <br />
