Tne a,.~dunt of overburden and topsoil removed aurin__ <br />initial cuts and stockpiled at each pit must be provided. Since <br />baci:filliny and grading and topsoil redistribution will be following <br />mining operations contemporaneously the worst case would be replacement <br />of stockpiled materials only. The application must be specific witri <br />respect to the volumes of material stockpiled. <br />The status of revegetation at Pits 1, 2, and 3 must be described in <br />greater detail. Tne Division will require sufficient funds to re vegetate <br />these areas in case of failure of recent efforts. <br />XXlI. Sealin: or Drilled <br />Z.U5.41[ lql ar.;, 4. <br />Holes and Underground upentngs - kuie: <br />Tne applicant proposes to seal drilled holes oy returning the drill <br />cuttings to the Dore hole. kules 4.07.3(1) and (2) require the placement <br />of an appropriate mechanical plug and concrete poured column near the <br />surface of eacn bored hole. The applicant should amend the application <br />document appropriately. If future drilling encounters water zones, the <br />Division should be notified, since it might be desiraole to retain the <br />Holes as monitoring wells. <br />XXIII. Special Categories of i~1ining Uther 7nan AVF and Prime Farnland - <br />kules [.U6, k.22, 4.23, 4.2b, 4.27 and 4.29 <br />Rule 2.06.9 - Special Categories of tdining - Auger (.lining <br />In general, the augering scheme appears acceptable. However, a few items <br />require additional description within the amended application document. <br />lieither the text of this section nor the schematic Figure No. 1 on page <br />V-16, mentioned the salvaging of topsoil prior to mining. The <br />application should be appropriately amended. The question regarding <br />backfilling of the angered areas to achieve approximate original contour <br />must be resolved, as discussed under Section XVI of this letter. <br />Further, the applicant's observation that augering downdip will preclude <br />drainage from the angered bore holes is insufficient. The applicant <br />should expand this discussion to demonstrate that the hydrologic heads <br />encountered will not be sufficient to cause ground water flour from the <br />bore openings, and provide a detailed description of the method of <br />sealing the auger openings. <br />XXV. Ptiscellaneous Compliance - Rules 2.05.6(5), 4.02, 4.12, 4.1 <br />4. <br />The Grassy Creek I4ine has experienced slides along the cut slopes on the <br />haul road. because this landslide potential demonstrably exists, the <br />applicant is required to include a statement in the application which <br />demonstrates an intent to comply with Rule 4.12(2). <br />1 <br />
