Dust emissions will be further mitigated by minimizing handling and re- <br />handling of raw and clean coal materials during operations. <br />The maximum proposed capacities of stockpiled coal products at the <br />facilities area are as follows: <br />- Raw coal stockpile 30,000 tons <br />- Combined clean coal stockpiles 25,000 tons <br />(industrial and stoker) <br />Upon completion of mining and prior to final reclamation, all remaining <br />stockpiled coal will be sold and removed from the site. Any remaining <br />unsaleable coal in minor quantities will be blended into overburden <br />materials, then placed and compacted during backfilling operations in <br />the facility area. <br />Truck Scale and Scale House <br />A truck scale will be installed along the mine haul road to weigh tractor <br />trailer and rear -dump haulage trucks transporting clean coal products <br />before they leave the mine property. The scale installation will include <br />a prefabricated truck scale mounted on a concrete box foundation with <br />0 minor approach ramps and pads. <br />Adjacent to the truck scale area, a scale house will be provided for <br />operating the electronic scale. All truck traffic entering and leaving the <br />site will be monitored from the facility. General construction and <br />dimensional information for the truck scale and scale house is provided <br />on Table 2.05.3 -2. <br />Upon completion of mining, the truck scale and scale house will be <br />removed and savaged, foundations will be demolished, resulting debris <br />will be placed in approved disposal areas on -site, and the associated <br />.disturbance are will be regraded, topsoiled, and revegetated. <br />Topsoil Stockpiles <br />During initial development of the surface facilities area at the <br />Northfield Mine, topsoil piles will be constructed to segregate and store <br />all available topsoil for use during final reclamation activities. <br />Construction methods of topsoil stockpiles will ensure that they are <br />located and oriented to provide long -term stability, minimize wind and <br />water erosion, and to prevent contamination or compaction of topsoil <br />resources. <br />Measures to protect the topsoil from erosion will include rough grading <br />the stockpile surfaces, and seeding with the temporary seed mixture, <br />2.05.3 -17 Revised 12/04/09, TR -01 <br />
