<br />Page 8 <br />H-G Preliminary Adequacy Review <br />2. A geotechnical analysis including those items described <br />in permanent regulation Section 2.05.3(5)(c) will have to <br />be performed and submitted in order for review of the application <br />to be completed. <br />2.05.4 Reclamation Plan <br />2.05.4(2)(a) A more detailed reclamation timetable is required. Exhibit D <br />needs to show the annual reclamation sequence. <br />2.05.4(2)(b) Revegetation costs seem to be very low. Please substantiate <br />or recalculate this figure. lJhat are the assumptions for <br />the 15% figure for calculating administrative costs? The <br />applicant should supply estimates for removal of buildings <br />and similar structures. <br />2.05.4(2)(c) 1. Inspection of the soil horizon description indicates that <br />there is nearly as much variability in the color of A horizons <br />as between A and B horizons within most profiles. Color or <br />hue differentiation 6y the equipment operator is not an adequate <br />method for determining stripping depth in itself. <br />2. How were the topsoil volumes derived for Table 3? Based on <br />the information presented in Exhibit T these volume estimates <br />could vary by a factor of 5 in some cases. Specificity of these <br />data is a critical issue with respect to development of topsoil <br />balance sheets. Please submit more specific information. <br />3. The re-submitted post mining contour map is not in con- <br />formance with concepts of AOC. The stream channel is over- <br />) steepened and over-channelized and does not appear to be based <br />l on sound geomorphic principles. Also, the applicant should <br />/ consider reconstructing the premining swale draining south to <br />north into the reconstructed channel (see Exhibit B). The <br />applicant must resubmit Exhibit D with a base map which depicts <br />undisturbed topography legibly. <br />4. The sediment ponds southwest of the pit along County <br />/ Road 53 have not yet been reclaimed. The applicant must <br />submit a plan for reconstructing the stream channel in this <br />area consistent with 4.05.4. <br />2.05.4(2)(g)(iv) Your response is not sufficiently detailed to satisfy all <br />questions in this section. For instance, have all drill holes <br />outside the disturbed area been properly plugged? blill <br />any new holes be drilled in the future, and how do you plan <br />to seal them, etc.? Please expand your response to answer <br />these issues. <br />
