are expected to exist for longer than one year, they will be seeded with a fast growing seed mix. <br /> Reclamation will occur once all mining has been completed. Fremont will use a contractor to <br /> blast the quarry at a 3H:1V grade. The highwalls will remain vertical during mining operations, <br /> but will be reclaimed to a 3H:1V grade. <br /> An external haul road from the site to Las Animas County Road 185 has been constructed. The <br /> road is 30 feet wide. Where the haul road intersects the county road, Fremont constructed a <br /> 2%valley pan with base course. <br /> No permanent structures will be necessary. Portable scales and sanitary facilities will be <br /> brought onsite during operation and removed when completed. <br /> Normal hours of operation during construction are proposed from 6 a.m. to 7 p.m., Monday <br /> through Saturday. Hours may extend into Sunday if an emergency demands additional hours. <br /> As many as 6 employees will operate the site during a one shift day. <br /> In the event noxious weeds appear,they will be managed mechanically and/or chemically as <br /> directed by the Las Animas County Noxious Weed Coordinator, Robert Lucero, and allowed by <br /> the property owner. <br /> Fugitive dust will be controlled by posting vehicle speed limit signs at 10 miles per hour <br /> throughout the site and a long haul roads, water spray application will be used at active <br /> extraction faces, stockpiles, and roads using a water truck. Fremont will purchase the water <br /> and haul it onsite for use. It is anticipated that approximately 10,000 gallons will be use daily <br /> for dust control. Stockpiles will be seeded if they are anticipated to exist for longer than one <br /> year. Haul roads will be graveled. These air quality control measures will also be included in <br /> the Colorado Department of Public Health and Environment, Air Pollution Control Division <br /> permit and fugitive dust plan. <br /> Stormwater management will be accomplished using best management practices which could <br /> include perimeter berms constructed of straw bales, waddles or overburden to direct any <br /> surface runoff from the affected area. All diversionary structures will be temporary and will be <br /> removed during reclamation. <br />
