• stable seedbed surface (Foidel), and/or only the "A" horizon is salvageable (Binco, Buckskin, Bulkley, <br />Cochetopa, Lymanson Variant, Routt, Teton, and Cochetopa Variant) due to excessive Gay in lower <br />horizons. <br />A thin veneer of suitable topsoil will be recovered from map Units 35C, 35D, 35E, and V46D. The surface <br />layer should have sufficient organic matter and roots to alleviate consistency, structure, and compaction <br />problems during topsoil handling. The surface 6-inches of topsoil from Map Units 101, 103, and 5103 will be <br />salvaged provided the salvaged topsoil is suitable (i.e., see Tab 9, Table &2), the rock fragment content is <br />less than 35 percent, and equipment can be operated safely. No topsoil is available to be salvaged from the <br />rock outcrop portion of Map Unit 10f. Peabody will obtain a variance pursuant to Rule 4.06.2(2) whenever <br />suitable topsoil cannot be salvaged from any map and because of equipment limitations or operator safety <br />concerns. <br />Minimal topsoil will be salvaged from Map Unit 5A. The Spicerton variant soil typically has a saline and sodic <br />subsoil with excessive clay throughout the entire profile. Six inches of topsoil is suitable for salvage from 7.2 <br />acres of This map unit near Sage Creek at the easf end of the tie-across haul road as shown on Exhibit 9-2. <br />Topsoil Storage. When the direct haul of topsoil is not feasible, the topsoil will be stored in approved <br />i stockpiles (see Operations Plan, Exhibit 12-2 and 12-3 and Exhibit 9-2, Soil Types and Topsoil Salvage Map <br />- Tie-Across Haul Road Corridor). The topsoil stockpile inventory presented in Table 21-3 and also in the <br />Annual Reclamation reports. Stockpiling of topsoil will be required for topsoil removal in the inRial box cut, <br />haul road, spoil stockpile areas, sediment pond, office and shop area, explosive storage area, and final <br />piUhighwall reduction areas. Topsoil stockpiles will be located in areas where they will not be disturbed or <br />contaminated by the ongoing mining operation and where the stored topsoil will not be lost to wind erosion or <br />Surface runoff. When a topsoil stockpile is placed, d will not be moved until soil is needed for distribution on <br />graded areas. Stockpile locations were also evaluated and selected to minimize scraper Vavel distance, to <br />reduce equipment cost, and to increase efficiency. <br />All topsoil stockpiles will be clearly distinguished and identified by approved signs. Mine personnel are <br />instructed that topsoil stockpiles are not to be disturbed or contaminated. The signs serve as continuing <br />reminders to personnel that stockpile areas are to be preserved and undisturbed. <br />C <br />PR03 25 Revised 7/02 <br />
