-4- XII Total acreage disturbed or proposed for disturbance within each ~,e/~~ vegetation type has been provided for Pit 4 and the Pit 4 haul road. Si mllar information should be provided for each of the disturbed areas. This information 1s needed since revegetation success standards will be based on the relative acreage of a reclaimed site formerly occupied by N ~ n particular vegetation types. A map should be provided which delineates~~` the year and season that each particular area was seeded. ~-~ Veaetatlon - Rules 2.04.10. 2.05.4(2)(e) and 4.15 S~ z XIII XV. The species diversity success standard proposed by the applicant is "at least five perennial species ...". Based upon the baseline data, the Division requests that the standard be changed to "at least four perennial grasses and one perennial forb ...". The wording of the livestock control plan should be modified to clarify that the plan applies to the entire permit term, and not dust 1984. If, in the future, the applicant wishes to allow grazing on the reclaimed I, areas, a grazing plan technical revision would need to be submitted to the Division for approval. For future revegetation success determinations, the applicant should specify whether one or both aspen reference areas will be utilized, and that mountain brush reference area 13 and sagebrush reference area 17 will be the sole reference areas for those respective vegetation types. This is due to the fact that mountain brush reference area 19 has been ~ disturbed by mining, and the estimated vegetative cover mean for suve~°v"5 sagebrush reference area 26 is significantly lower than the estimated p,~.~~ affected area mean. ~ {,p- Fish and Wildlife - Rules 2.04.11. 2.05.6(2) and 4.18 sGi"~ The statement in the application indicating that vegetation manipulation as a wildlife mitigation technique is "not compatible with the goals of the Mined Land Reclamation Division" is not true and should be deleted from the application. Dozer "brushing" is a required mitigation measure at a number of mines 1n northwestern Colorado. At Grassy Gap, 1t has been determined that, given the limited amount of disturbance and high elevation (mine area forage 1s not available to deer and elk in severe winters), off-site vegetation manipulation will not be required. The following specific information regarding mining at Pit 4 1s necessary. a) Coal seams to be extracted. b) Maximum depth of extraction.
