• topsoil fertility section, Attachment 9-4. Occasionally, topsoil from the Hayden Gulch <br />Terminal site may exceed the recommended suitability ranges shown in Table 19-2. Such <br />exceedences have been identified, on occasion, for Conductivity, sodium adsorption ratio, <br />calcium carbonate percentage, clay content, and coarse fragments. <br />ToDSOiI Salvage <br />Site clearing and topsoil salvage operations associated with facility construction have <br />been completed. A small area, about 0.2 acres, within the Disturbed Land, Topsoiled map <br />unit will be redisturbed when constructing Hayden Gulch Loadout Facility Haul Road 2 (HGLF <br />HR2) as depicted on Exhibits 9-7 and 12-7. All suitable soil will be salvaged prior to <br />constructing the road. No additional disturbances are contemplated while operating the <br />loedout facility; however, should the need arise to disturb additional areas, topsoil <br />would be salvaged according to the schedule presented in Tab 17. All suitable soil, based <br />upon the soil types identified in Attachments 9-1 end 9-2 (Tab 9), could be salvaged to <br />the specified depths prior to any significant disturbance. <br />• Topsoil will be removed by using self-loading scrapers, push scrapers, or other rubber <br />tired equipment. A dozer or road grader will also be used when needed to assist scraper <br />loading, to fatilite[e maximum Cops oil recovery, and to help build end shape topsoil <br />stockpiles. Yhere topsoil exists on a steep slope and where there is enough room for <br />scrapers to maneuver et the bottom of that slope, fopsoil will be removed by being pushed <br />downhill with a dozer, picked up with scrapers, then stockpiled or transferred directly to <br />final graded areas. In other steep slope situations, topsoil removed by dozers will be <br />pushed outside of the topsoil disturbance area end stared in approved stockpiles at the <br />bottom of that slope. <br />Topsoil will be salvaged from four map units identified on Exhibit 9-1 and Table 19-3 <br />during final reclamation of the coal loedout and rail facility. The soil material within <br />the Disturbed Land, Topsoiled map unit will be selvaged prior to final grading and <br />replaced within the same Brea. Suitable topsoil from the post-operational disturbance <br />area, which includes map units SAI, 7C, and 10C, will be salvaged prior to final slope <br />reduction es described in Tabs 17 and 18. <br />• TODSOiI Storage <br />Topsoil is stored in three stockpiles as shown on Exhibit 9-1, Soil Types, Sample Sites, <br />} Revised 03/01/93 <br />
