Box 338 MINING AND SAFETY <br /> Cotopaxi, Colorado 81223 <br /> 719-942-4178 <br /> March 9, 2017 <br /> State of Colorado <br /> Department of Natural Resources <br /> Division of Reclamation, Mining, and Safety <br /> 1313 Sherman Street, Room 215 <br /> Denver, CO 80203 <br /> Attention: Tim Cazier, PE, Environmental Protection Specialist <br /> RE: PERMIT NUMBER M-77-193 TEZAK HEAVY EQUIPMENT T.H.E. <br /> AGGREGATE SOURCE, APPLICATION FOR TECHNICAL REVISION <br /> This request for technical revision to permit is to address the construction of a process <br /> fines stockpile/permanent storage structure within the existing bonded property <br /> boundaries. <br /> The storage area will be located on Tezak Heavy Equipment property in the southwest <br /> corner of the permit area. The structure will encompass 10 acres of footprint at its base, <br /> spanning dimensions of 850'long and up to 600' deep from toe to top of structure near <br /> the top of the existing highwall benches. Maximum final height of the structure will top <br /> off at 1931rom toe of structure to highest fill elevation along the west permit boundary. <br /> At maximum build out, the stockpile will contain approximately 1 million tons of granite <br /> sand and fine aggregate. <br /> Materials and Construction <br /> The material composing the structure is a fine to course grained granite derived sand and <br /> fine aggregate containing varying amounts of potassium feldspar, quartz, and biotite. <br /> The material size is typically 100% passing a 3/8" sieve with generally 15% passing a <br /> 200-mesh sieve. <br /> A typical sizing analysis of fill material is included in this filing. <br /> The granite fines will be placed and compacted at one foot intervals. All fill materials <br /> will be watered in place prior to transport to final placement and compacted by means of <br /> haul truck or loader wheel packing, bulldozer track packing or sheep's foot type <br /> compactor application. The west side of the storage pile will lie directly up against the <br /> current highwall benches. The east face and northeast face of the proposed storage <br /> structure will be sloped not to exceed 3:1 Horizontal: Vertical overall slope. <br /> The top 12" of the surface of the storage facility will be covered with planting medium <br /> composed of rocky soils recovered from nearby stripping operations of surface materials <br />
