-2- Exhibit E 1. We have reviewed the settlement agreement, and concur with Me that the 3 inch material stockpile must be removed or reclai this structure been permitted under normal procedures, a deta reclamation plan would have been required. Please submit a d reclamation plan for this structure. a County d. Had led tailed It is our opinion that the two most preferable options for re laiming the material stockpile are (1) removal from the site, or (2) back filling against the highwall. When developing a reclamation plan for this stockpile, long-term slope stability should be a primary conc rn. Items such as potential slope failure, erosion potential, and usabi ity of the land form should be considered. 2. The proposed backfilled portion of the quarry (Sections A-A', B-B') vary from a 1~ slope to a 20~ slope. This amount of slope variati n is too great. Please commit to a minimal slope gradient of not less than 15%. This slope should begin at the Highway 141 berm, and continue to the highwall face. Exhibit F 1. The Reclamation P1 an Map should be amended to show the new pe it boundaries. The new map should also depict the post-mining t pography, given comment E2, above. Exhibit L 1. An integral part of the site reclamation will be the removal, or backfilling of, the 3 inch material stockpile. Reclamation o this structure is required by the settlement agreement, and is req fired by the (dined Land Reclamation Act. As the reclamation of this strut ure is an outstanding liability to the permittee, the cost of performin this reclamation task must be included in Exhibit L, and as part o the financial warranty. Given the two potential reclamation options suggested in Comm nt E1, two separate cost estimates could be developed. If the material were to be removed from the site, the reclama ion cost estimate should include the following: a. small dozer (D-5 equivalent) to push material downslope; b. loader to place material in haul trucks; c. haul trucks to transport material at least 15 miles. If the material is to be used as backfill at the highwall, the cost estimate should include: a, small self-loading scraper (613/615 or equivalent) to move material;
