._ „ iii iiiiiiiiiiiu iii The Corley Company Pl~ona 632-5050 P.O. Boa IB21 COLORADO SPRINGS COLORADO 80901 Oct. 29, 1993 V s Mr. Daniel I, Hernandez r I`9.9~ Division of Minerals b Geology 1313 Sherman St. Denver CO 80203 Dear Mr. Hernandez: We have several comments regarding your draft of the proposed East Pit reclamation. While the entire plan consists of one written page and several topo maps and cross-sections, there are not sufficient specifics to be entirely certain of the intent of some of the tasks. However, task 1 would reduce Chen's Hill to 3H: 1V and cut 35 feet from the top. Cross-section EE' does not demonstrate a 35' cut. The topo "Chens Hill Final" does not show any cut of the top in comparison to "Chens Hill Existing 2V:1H". Of greater importance is the elimination of the existing road. While task 3 would reestablish access to the Monarch fan, there is no indication of the location or timing of the new road. Energy Fuels, one of our neighbors, and ourselves need continuous access. While Energy could use access through another alignment, our neighbor cannot enter through Energy's tipple area. Task 2 is not specific about diversion ditches or dozer basins with regard to size or location. Task 3 does not specify the new road location. Task 4 does not specify saving topsoil in the 100 foot cut area. Do you really want D10s working up to the edge of the high wall? The "East Pit Final Contour 2V:1H" map would seem [o have the wrong title. 2V:IH? Y,ind of steep. Task 5 calls for 62,000 cu. yd. of topsoil in present stock piles. Is that a realistic volume? Additional topsoil if needed would be taken from the east side. Is it a good practice to rob an undisturbed area? Task 6 does not specify the seed mix, amount or method of seeding, mulching, or other additive. With regard to cost estimates, four DLONs and two 627s are the bases of the estimates. Since there are no D10s and probably ro 627s in the area, the mobilization. estimate of $6000 is extremely low. I doubt that the new road can be established for $1,]00, and supplies for the revegetation will cost more than $300 per acre assuming that usual revegetation practices are used.
