topsoil fertility section, attachment 9 -4. Occasionally, topsoil from the Hayden Gulch Terminal site may exceed the recommended suitability ranges shown in Table 19 -2. Such exceedences have been identified, on occasion, for conductivity, sodium adsorption ratio, calcium carbonate percentage, clay content, and course fragments. Topsoil Salvage Loadout Facility: Site clearing and topsoil salvage operations associated with facility construction have been completed. A small area, about 0.2 acres, within the Disturbed Lands, Topsoiled map unit will be redisturbed when constructing Hayden Gulch Loadout Facility Haul Road 2 (HGLF HR2) as depicted on Exhibits 9 -1 and 12 -1. All suitable soil will be salvaged prior to constructing the road. No additional disturbances are contemplated while operating the loadout facility; however, should the need arise to disturb additional areas, topsoil would be salvaged according to the schedule presented in Tab 17. All suitable soil, based upon the soil types identified in Attachments 9 -1 and 9 -2 (Tab 9), would be salvaged to the specified depths prior to any significant disturbance. Topsoil will be removed by using self - loading scrapers, push scrapers, or other rubber tired equipment. A dozer or road grader will also be used when needed to assist scraper loading, to facilitate maximum topsoil recovery, and to help build and shape topsoil stockpiles. Where topsoil exists on a steep slope and where there is enough room for scrapers to maneuver at the bottom of that slope, topsoil will be removed by being pushed downhill with a dozer, picked up with scrapers, then stockpiled or transferred directly to final graded areas. In other steep slope situations, topsoil removed by dozers will be pushed outside of the topsoil disturbance area and stored in approved stockpiles at the bottom of that slope. Topsoil will be salvaged from four map units identified on Exhibit 9 -1 and Table 19 -3 for replacement during final reclamation of the coal loadout and rail facility. The soil material within the Disturbed Land, Topsoiled map unit will be salvaged prior to final grading and replaced within the same area. Suitable topsoil from the poet - operational disturbance area, which includes map units 5AI, 7C and 10C, will be salvaged prior to final slope reduction as described in Tabs 17 and 18. TAHR: The map units and salvage depths are presented on Exhibit 9 -2, Soil Types & Topsoil Salvage Map Tie - Across Haul Road (from the Seneca II -W permit document). Topsoil Storage Topsoil is stored in three stockpiles at the HG loadout area and in six stockpiles along the TAHR as shown on Exhibit 9 -1, Soil Types, Sample Sites and Topsoil Stockpiles and Exhibit 9 -2, Soil Types & Topsoil Salvage Map Tie - Across Haul Road. Approximately 34 ac -ft of suitable topsoil material is available for replacement at the loadout facility and 72.7 ac -ft on the TAHR. PR -1 3 revised 10/11
