I • 2-35 <br />In the footprint of the construction material stockpile, topsoil was stripped to a <br />depth of 12-inches and placed in the topsoil stockpile. The resulting depression along <br />with a perimeter ditch and silt fence are used to treat the run-off from the construction <br />material stockpile. Design of the silt fence for the construction material stockpile (SAE- <br />3) is contained in Appendix M, page M-2. The topsoil stockpile and construction <br />material stockpiles will be seeded with the temporary revegetation seed mix in the fall of <br />each year they are,disturbed. No seeding will be necessary if the piles are not <br />disturbed during the year, <br />A sediment drying area is located adjacent to the sediment pond. Sediment <br />cleaned from ditches and the sediment pond is placed in this pile for drying before the <br />material is hauled to a suitable stockpile. Material that is comprised of coal fines and <br />larger coal material will be periodically hauled to the Munger coal waste storage pile for <br />final disposal. Material that does not have a significant coal component will be placed <br />in the construction material stockpile. The maximum capacity of the sediment drying <br />area is 1,000 cubic yards. <br />• 2.2.4 Access Control Features <br />Existing fences and signs will be used to control access to the permit area. All <br />signs will be of standard design, using durable material that can readily be seen and <br />read in accordance with appropriate regulations. The signs will not be removed until <br />after release of all bonds. <br />Access to and from Colorado Highway 139 will be in accordance with safety <br />requirements of the Colorado State Highway Department. <br />LJ <br />M`Clane Volume 1 06/04 <br />
