stable seedbed surface IFoidel), and/or only the "A" horizon is salvageable IBinco, Buckskin, Bulkley, <br />Cochetopa, Lymanson Variant, Routt, Teton, and Cochetopa Variant) due [o excessive clay in lower <br />horizons. <br />A thin veneer of suitable topsoil will be recovered from map Units 35C, 35D, and 35E. The surface <br />layer should have sufficient organic matter and roots to alleviate consistency, structure, and <br />compaction problems during topsoil handling. The surface 6-inches of topsoil from Map Units 101, <br />103, and 5103 will be salvaged provided the salvaged topsoil is suitable li.e., see Tab 9, Table 9-21, <br />the rock fragment content is less than 35 percent, and equipment can be operated safely. No topsoil is <br />available to be salvaged from the rock outcrop portion of Map Uni[ 101. Peabody will obtain a variance <br />pursuant to Rule 4.06.2121 whenever suitable topsoil cannot be salvaged from any map unit because of <br />equipment limitations or operator safety concerns. <br />Minimal topsoil will be salvaged from Map Unit 5A. The Spicerton variant soil typically has a saline and <br />sodic subsoil with excessive clay throughout the entire profile. Six inches of topsoil is suitable for <br />salvage from 7.2 acres of this map unit near Sage Creek at the east end of the tie-across haul road as <br />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 />stockpiles Isee Operations Plan, Exhibit 12-2 and 12-3 and Exhibit 9-2, Soil Types and Topsoil Salvage <br />Map -Tie-Across Haul Road Corridorl. The topsoil stockpile inventory through the first permit term <br />11 98 9-1 9951 is presented in Table 21-3. Stockpiling of topsoil will be required for topsoil removal in <br />the initial box cut, haul road, spoil stockpile areas, sediment pond, office and shop area, explosive <br />storage area, and final pit/highwall reduction areas. Topsoil stockpiles will be located in areas where <br />they will not be disturbed or contaminated by the ongoing mining operation and where the stored <br />topsoil will not be lost to wind erosion or surface runoff. When a topsoil stockpile is placed, it will not <br />be moved until soil is needed for distribution on graded areas. Stockpile locations were also evaluated <br />and selected to minimize scraper travel distance, to 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 <br />continuing reminders to personnel that stockpile areas are to be preserved and undisturbed. <br /> <br />25 Revised 9/98 <br />
