<br />side slopes. The berms along the west side of County Road 25 will have an average height of 4 <br />feet. The topsoil stockpiles will be protected from wind and water erosion by vegetative cover (see <br />the Seed Mix for Upland Areas found on page E6 of Exhibit E). The stockpiles will be broadcast <br />seeded and incorporated into the weed control program. Weed control consists of monthly <br />inspections and, if necessary, chemical treatments in the applicable fall and spring seasons. Topsoil <br />stockpiles that will be in place for more than 180 days will be vegetated depending on the seeding <br />"window" parameters for dryland grass, which are typically between September and April. <br />The overburden stockpiles will be continuously rotating. Initially, a portion of a phase will be <br />stripped and the overburden stockpiled temporarily within the permit boundaries. Once the deposit <br />has been mined from the stripped portion, the temporary stockpile will be removed and used for <br />reclamation. The remaining portion of the cell will then be stripped and the overburden will be <br />stockpiled on the mine floor or placed immediately in the reclamation slope. With the exception of <br />the landscape berms shown north and east of Phase 2, there will be no permanent stockpiles at this <br />site; all extra overburden will be used to create undulating shorelines. <br />Commodities to be Mined <br />The primary commodity to be mined will be aggregate and a secondary commodity will be gold. <br />Lafarge will supply local, county, and state governments, as well as private industry with aggregate <br />from this facility. If gold is to be mined it will be used for commercial purposes. <br />Offsets <br />Lafarge will maintain mining offsets from sensitive areas designated for protection and all <br />structures according to the Geotechnical Slope Analysis included in the Stability Exhibit. Setbacks <br />were determined for each boundary and vary from 25 feet to 46 feet from structures. See Exhibit S <br />and the Stability Exhibit for specifics. The Whitney Ditch, which traverses the north edge of the <br />property boundary, will need to be relocated to accommodate additional right-of-way required for <br />road improvements. Lafarge will relocate the ditch prior to the mining process and is working with <br />the Ditch Company to obtain a formal agreement. There are some individual property lateral <br />ditches will be eliminated. Some of the laterals are on the property owned by Lafarge so no consent <br />agreement to mine through these laterals will be necessary. For the laterals on the property owned <br />by Sally Parsons and Livingston Leigh Livestock of Weld County, the lease agreements that <br />Lafarge has with both of these property owners address the right to mine through lateral ditches <br />(please see lease agreements provided in Exhibit N). <br />Roads and Conveyors <br />Preparation for mining for each phase will include a 15' wide gravel access road around the <br />perimeter of the cell. Any additional short-term haul access will be constructed with 6" of native <br />sand and gravel from the floor of the mine. These gravel roads will be removed and reclaimed as <br />mining and reclamation is completed for each phase. These areas have been included in the <br />permitted acreage. <br />The majority of the material will be transported from the mining face to the processing area via <br />conveyors. There are two proposed conveyor crossings of County Road 25. The northern most <br />crossing (between Phases IA and 2) will be utilized during the mining of Phase 2 and the southern- <br />most crossing (between Phases 4A/413 and 3) will be utilized during the mining of Phases 4A <br />Parsons Mine <br />DRMS 112 Reclamation Permit Application <br />Page D3 of D5
