<br />Progresso-Bond complex soils, map unit 30C. The 30C soils will be salvaged, stored, and <br />replaced in two separate lifts. Seed mix No. 6 will be seeded on these lands. Revegetation <br />success standards are found in Permit Section 2.05.4(2)(e). The productivity standard will <br />be based on NRCS data for the Progresso-Bond complex soil type. The cover standard will <br />be based on baseline data and has been set at 90% of 72% total ground cover. <br />Dryland pasture comprises approximately 96 acres on the Mine 2 azea. Dryland pasture will <br />be replaced in azeas that were limited by topography, soil depth, and rock outcrops in the <br />pre-mining landscape. The soils on the dryland pasture areas tend to be thin, rocky, and <br />exhibit low productivity. Soils on these lands will be salvage, stored, and replaced in one <br />lift of mixed A-C horizons. Approximately 21 acres in the SW portion of the Mine 2 permit <br />area will not receive topsoil application. Western Fuels has provided information that <br />subsoil/overburden material is suitable for plant growth media. Seed mix No. 8 will be <br />seeded onto the dryland pasture type. Reclamation success standards will be based upon <br />NRCS standards, while cover standards will be based on 90% of the cover of the associated <br />upland sagebrush reference area. No woody stem standard is applicable since local <br />management of pasture land is to eliminate woody species. Woody species aze not <br />necessary nor desirable in the pasture-lands. <br />Western Fuels has committed to establishing hedgerows of Russian Olive and cotoneaster. <br />Additionally, two groupings of cottonwood and mulberry will be planted. <br />Posturing land use of Rangeland exists in the Mine 1 area. The Rangeland areas have a soil <br />replacement thickness of 10 inches. The cover success standard will utilize an Upland <br />Sagebrush reference area. Production success will be based on NRCS potential productivity <br />data for the associated soil types. Woody stem desity has been set at 750 stems per acre. <br />Species diversity is applicable to the rangeland sites and is elaborated on page 22-12 of the <br />permit. <br />Concerns that I have identified during this review include: <br />T 1) Page 2.05.4(2)(d)-7 contains the statement that "One lift topsoil will <br />generally be isolated from the two lifts during all soil handling <br />operations". Soil units D70B and 30C are to handled, (Stripped, stored <br />and replaced}, in two lift operations. Other soil types tend to be <br />thinner, rockier, and less productive and will be handled in one lift, <br />mixed horizon salvage, storage and replacement. The word generally <br />should be stricken from the above statement since according to the <br />approved reclamation plan, there should be no mixing of the two lift <br />soils and the single lift soils. Additionally, Western Fuels should be <br />reminded that D70B soils need to be stored separately from 30C soils. <br />V 2) a) Page 2.05.4(2)(d)-8 describes the seedmix to be used on temporary <br />topsoil piles. In TR-28 Western Fuels has proposed to change the rate <br />of the temporary seed mix. Since the Division has no problem with <br />the rates proposed in TR-28, Western Fuels should bring this page into <br />
