-34- Air pollution control measures (30 mph speed limits and haul road watering) are listed on Page V-1 of the application. The Rockcastle Company has obtained an emission permit from the Colorado Department of Health, but the permit was not included in the application. The following stipulation is required: Stipulation No. 5: WITHIN 1 MONTH OF PUBLICATION OF THE PROPOSED DECISION, THE PERMITTEE WILL SUBMIT 3 COPIES OF THE FINAL APPROVED AIR EMISSION PERMIT FOR INCLUSION IN THE APPLICATION. With the above stipulation, the proposed operation is in compliance with the requirements of this section. XI. Topsoil - Rules 2.04.9, 2.05.3(5), 2.05.4(2)(d) and 4.06 Soils resource information is presented on pages II.1-1 through II.I-29 of the application. A description of topsoil salvage and storage is provided on Pages III-28 through III-30 and topsoil redistribution is discussed on pages IV-5 through IV-8. Three soil types (four mapping units) will be affected by mining at Pit 4 this permit term. The soil types are Winevada Splitro Complex, Coutis fine sandy loam and Winevada fine sandy loam. The soils are all mollisols with relatively deep, well developed A horizons. The soils are well drained loams and fine sandy loams with physical and chemical properties well suited for revegetation. Soil mapping units were based on an SCS Order III level survey, but the map was refined based on at least one sampling site in each mapping unit. Soil samples for separate horizons were analyzed from 13 locations representing 9 soils and 11 mapping units in the permit area. Mapping units down to approximately 3 acres were delineated. The applicant proposes to salvage all A horizon material. Based on soil depth information presented in the Soil Resource Information section of the application, sufficient soil will be available to respread a two foot layer on regraded spoils. A topsoil buffer zone of at least 30 feet will be maintained in advance of the highwall. When regraded overburden is available, topsoil stripped ahead of pit advance will be replaced directly on the graded spoils. The regraded spoils of the final cut will be topsoiled with soil removed and stockpiled during initial pit development at Pit 4. The proposed operation is in compliance with the requirements of this section.
