6. General Mine Conditions <br /> The Existing Conditions Map shows the current conditions of the Lascar Pit. The pit will <br /> provide aggregate for local construction including gravel,road base, and landscape aggregate. <br /> Incidental materials not used for construction material will be used to reconstruct the pit floor <br /> and lessen the pit slopes. Mining will disturb up to 30 acres as shown on the Mining Map. The <br /> current operation under the 111 permit has disturbed approximately 6 acres of the 30-acre <br /> permit area. <br /> Mine access is via County Road 650 with access from Interstate 25. Mining of the gravel <br /> deposit will progress from the west side of the permit boundary and move to the east of the <br /> site. Earthmoving will be accomplished using front end loaders and scrapers. Aggregate will <br /> be processed and sized using a crusher and screens. All equipment is portable. Stockpile and <br /> processing areas will be in the southwest corner of the site. The pit will be sloped to a 3H:1 V <br /> or shallower to restore the site's previous drainage pattern. <br /> A portable asphalt hot plant or concrete plant may be located at the site and will be located <br /> inside of the processing area as shown on the Mining Map. This area,as well as the stockpile <br /> and processing areas, will be prepped by removing and stockpiling topsoil for later <br /> reclamation. Mined and processed aggregate will be stored surrounding the portable <br /> processing plant(s). Topsoil and overburden berms will be stored around the perimeter of the <br /> permit boundary for later use in reclamation. <br /> 7. Mining Timetable <br /> The life of the proposed operation is difficult to quantify due to changing economic <br /> conditions in the construction industry and onsite aggregate quality. It is anticipated that the <br /> site will have a life of approximately 5 years. <br /> 8. Mine Facilities and Operation <br /> Toxic or acid-producing materials will not be encountered during the mining operation.No <br /> blasting or explosives will occur/be used during mining nor on site. Bulk storage of fuel and <br /> small amounts of lubricants may be stored on site and will be either double walled or housed <br /> Page 8 of 24 <br />
