-30- XI. Topsoil -Rules 2.04.9, 2.05.3(5), 2.05.4(2)(d), and 4.06 Soil resources information and the topsoil management plan have been reviewed by the Division. Baseline soils information for the approved permit area can be found in Exhibit 7R2, Volume I, and Section 2.04.9, Volume I of the permit application. The topsoil management plan can be found in Exhibit 18R2, Volume II, Section 2.05.3, Volume 1, and Section 2.05.4, Volume 1, of the permit application. The Permit Revision No. 2 area is within a Corta-Carracas -Nunn soil association. Soil types within the proposed permit area include the following snapping units: Panitchen variant silt loam; Flugle variant - Mikim variant gravelly sandy loam complex; Carracas loam; Paralithic clay shale-sandstone-carbonaceous shale-rock outcrop complex; Celacy variant silt loam, and the Nunn variant loam. The Paralithic clay shale material is unsuitable for reclamation purposes. All other mapped soil units have suitable topsoil material with recommended stripping depths ranging from 14 to 72 inches. The Nunn variant loam is situated outside the affected area and as such will remain undisturbed. Topsoil redistribution operations will result in an average replacement depth of 2.81 feet over regraded areas. The applicant states that, "at least 6 inches of soil will be replaced in all areas with the average replacement depth estimated to be 35 inches. In order to ensure revegetation success, and to utilize all available topsoil the operator has committed to replace an average of 30 inches of topsoil over the entire disturbed area. Chimney Rock salvages all available soil material ahead of the active pit. This material is then stockpiled and seeded to stabilize the stockpiles. No direct haul topsoiling is proposed for the Deep Creek area. The existing and proposed operations are found to be in compliance with the requirements of this section. XII. Vegetation - Rules 2.04.10, 2.05.4(2)(e), 4.15, and 4.18(4)(1) The Division has reviewed the permit application for compliance with these sections. Information on baseline vegetation for the Permit Revision No. 2 area can be found in Exhibit 8R2 Volume II and supplemental submittals of February 8, 25, 1985 and April 12, 18, 1985. Information on tfie revegetation plan and revegetation success criteria for the permit revision application can be found in Section 2.05.4 Volume I, Exhibit 18R2 (Volume II) and the supplemental submittals. Quantitative vegetation studies were undertaken in the Deep Creek area in 1983 by Mariah Associates. Three vegetative communities were identified in which disturbance will occur, sparse pinyon-juniper, mixed bursh-conifer, and
