<br />12. Please commit to use of 1 ton per acre certified weed free straw or hay mulch crimped into <br />the surface after seed application. <br />13.Your response indicates that the small drainage cutting through the south end of the permit <br />area will not be intercepted by excavation activities. However, the application maps, and your <br />representative on site during the pre-operational inspection indicated that the drainage would <br />be intercepted and is actually the location of the proposed Phase 1 sediment pond. Please <br />clarify this discrepancy. <br />14. Response adequate. <br />15. Response adequate. <br />16.See enclosed reclamation cost estimate that includes costs for mulch and weed control <br />applications. The estimate was calculated using a loader to transport waste rock, overburden <br />and topsoil from stockpiles to the pit for placement at reclamation (see explanation in no. 17 <br />belowl. Please review this cost estimate carefully and notify DMG of any calculation errors. <br />This estimate may be revised prior to a decision on this application if your responses to the <br />remaining adequacy questions significantly change the mining or reclamation operations. <br />17,H and H Stone may need to contact the Army Corps of Engineers regarding possible discharge <br />of materials into the Waters of the U.S. because of the proposed location for the waste rock, <br />overburden and topsoil stockpiles, and the proposed operation of using a bulldozer to strip <br />these materials and push them across the small south drainage and into stockpiles at the south <br />end of the pit. Exhibit M may need to be modified to include a permit from the Corps of <br />Engineers unless H and H Stone modifies the mining and reclamation plans to locate the <br />stockpiles where the material would not have to cross a drainage, or modify these plans to <br />indicate that all material would be transported across the drainage in bucketed equipment, not <br />pushed across the drainage. <br />18.
