Hernandez <br /> Division of Minerals 6 Geology <br /> 1313 Sherman St. <br /> Denver CO 80203 <br /> Dear Mr. Hernandez: <br /> We have several comments regarding your draft of the proposed East Pit <br /> reclamation. <br /> While the entire plan consists of one written page and several topo maps <br /> and cross—sections, there are not sufficient specifics to be entirely <br /> certain of the intent of some of the tasks. <br /> However, task 1 would reduce Chen's Hill to 3H: IV and cut 35 feet from <br /> the top. Cross—section EE' does not demonstrate a 35' cut. The topo <br /> "Chens Hill Final" does not show any cut of the top in comparison to <br /> "Chens Hill Existing 2V: IH". Of greater importance is the elimination <br /> of the existing road. While task 3 would reestablish access to the <br /> Monarch fan, there is no indication of the location or timing of the new <br /> road. Energy Fuels, one of our neighbors, and ourselves need continuous <br /> access. While Energy could use access through another alignment, our <br /> neighbor cannot enter through Energy's tipple area. <br /> Task 2 is not specific about diversion ditches or dozer basins with <br /> regard to size or location. <br /> Task 3 does not specify the- new- road- location.--- - - - - - - <br /> Task 4 does not specify saving topsoil in the 100 foot cut area. Do you <br /> really want D10s working up to the edge of the high wall? The "East Pit <br /> Final Contour 2V: 1H" map would seem to have the wrong title. 2V: IH? <br /> Kind of steep. <br /> Task 5 calls for 62,000 cu. yd. of topsoil in present stock piles. Is <br /> that a realistic volume? Additional topsoil if needed would be taken <br /> from the east side. Is it a good practice to rob an undisturbed area? <br /> Task 6 does not specify the seed mix, amount or method of seeding, <br /> mulching, or other additive. <br /> With regard to cost estimates, four D1ONs and two 627s are the bases of <br /> the estimates. Since there are no D10s and probably no 627s in the <br /> area, the mobilization estimate of $6000 is extremely low. I doubt that <br /> the new road can be established for $1 , 100, and supplies for the <br /> revegetation will cost more than $300 per acre assuming that usual <br /> r.evegetation - practices, are- used. - - -- <br />
