Rule 2.05.4(2)(E) Revised 8/15/84 Section 816.116(a) Continued. County Area Soil Survey (available at SCS Office, Walden, Colorado) has a scrubby big sagebrush aspect. Soil conditions are variable. Soils may be deep to shallow, well-drained, moderately coarse textured with moderate to rapid permeability and low to high available water capacity. The reclaimed site will probably have similar characteristics. Topsoil will be shallow, well drained, moderate permeability with a moderate water capacity. The reclaimed plant community is expected to resemble the valley bench plant community Kerr Coal sampled the Reference Area at the Kerr Tipple on July 15, 1981. Data was collected for percent plant cover, production, species diversity, and shrub density. These data and a species list of the plants identified at the Kerr Tipple Reference Area are • presented in Exhibit 59, Attachment B, Tables 1 and 2. Based upon the percent composition of the plant species found on the Reference Area, species diversity on the reclaimed areas at the Rerr Tipple will be deemed to have been successfully accomplished when the three dominant plant species on the reclaimed area account for at least 54Y. of the plant composition and do not account for more than 75% of the plant composition, provided that at least one of the three dominant plant species is a fotb and that none of the three dominant plant species comprise less than three percent of the total plant composition. As previously agreed when the Reference Area was identified, the percent cover and the production from the Reference Area at the end of the liability period will be utilized as the cover and production standards against which revegetation success at the Ketr Tipple will be measured. Re vegetation will be deemed successful with respect to cover and production when at least 90X of the reference area values for total 816-157b
