be shot to a size suitable for reclamation and stockpiled. with any topsoil encountered during mining. To what size will the overburden intended for use during reclamation be shot'? Please indicate on the Mining Plan Map, Exhibit C, where the fine material will be stockpiled. The applicant should commit to stockpiling enough top soil and fine sandy overburden material to provide a 6 inch cover on all mined areas to be reclaimed. EXHIBIT E - Reclamation Plan 8. The Reclamation Plan includes tree pads, stone berm filters, loadout benches and stock water basins. The addendum states that tree pads will be used principally in areas which have insufficient sandy overburden for bench construction and more sparingly in the benched areas. The applicant stated in the addendum that the overall tree pad surface area per acre was not applicable to this plan due to uncertainties with the number and location of the benches. It was discussed during the informal conference on December 10, 1993 that the operator would agree to leaving half of the loadout benches in place for reclamation. Tree pad:; will be used in places where benches are removed. More details are needed to calculate a financial warranty. Please provide the approximate locations, the sizes, and designs of these structures in the reclamation plan and on the Reclamation :Plan map, Exhibit F, Sheet 2. The placement of these structures ::hould be staggered to limit the runoff slope length between structures. Permanent structures must be designed to handle runoff from 100 year/24 hour precipitation events. Since the applicant has stated that the arrangement and length of each tree pad and bench will be random, the Division requires that the water storage cap~ibilities for each structure be calculated based on the appropriate runoff from the specific watershed above each structure. 9. Soil Replacement - As discussed in no. 5 above, include a commitment to replace a minimum thickness of topsoil and fine sandy overburden, such as 6 inches, prior to reseeding all disturbed areas, including the sandstone slab. It must be demonstrz~ted that sufficient material will be available to do this. The Division recognizes that the applicant committed to replacing 6 inches of topsoil on the tree pads in the original amendment. Prior to reseeding, the applicant must commit to soil characterization to ensure the material will support tree growth and grasses. 10. Reclamation Seed Mix - The Division agrees with ~:he Fort Collins Soil Conservation Division that all disturbed areas, including the sandstone slab, except remaining roads should be seeded with the seed mix recommended by the Soil Conservation Service. The one exception to this would be on the bench slopes where it is recommended that 2 lbs. PLS Mountain Mahogany and 4 lbs. PLS Indian Ricegrass be planted. The Indian Ricegrass will 3
