This TR is requested to landfill "Distressed Coal" inside the permitted mine area in the <br />quarry. The coal originated in the Powder River Basin of Wyoming. The coal contains inert rock <br />of various sizes. In 2009 Holcim screened the material to separate the rock and coal for use in <br />Holcim's kiln. Holcim is requesting to landfill the screened reject product in the quarry. The <br />estimated volume of the reject material is 20,000 tons. <br />The reject material will be hauled to the quarry by dump trucks. The material will be placed in 2 <br />foot lifts, spread using a D9R Dozer and stabilized to a 3:1 slope. After the haulage is completed <br />the landfilled area will be covered with topsoil and seeded with native grasses consistent with <br />Holcim's reclamation seeding plan. <br />Figure 1 shows the location the material will be landfilled and the materials current location at the <br />plant. The landfilled area will not affect the approved reclamation plan for the quarry since the <br />landfill is outside of the current mine area. The rejected material consists of rock and stone with <br />approximately 35% coal. The material will not release any pollutants to the groundwater nor will it <br />affect the surface drainage system in the area. <br />Plate 2: Wider view of screened reject <br />Plate 1: Close-up view of screened reject
