6.3.2 EXHIBIT C <br /> MINING PLAN <br /> 1. General Mining Plan <br /> The Existing Conditions Map shows the current conditions of the Lascar Pit. The pit will provide <br /> aggregate for road construction work on Colorado Project No. FBR 025A-045 and Federal Highway <br /> Administration Project 6982AF23C000001. Mining will disturb up to 30 acres as shown on the <br /> Mining Map. <br /> Mine access is via County Road 650 with access from Interstate 25. Mining of the gravel deposit <br /> will progress from the west side of the permit boundary and move to the east of the site. <br /> Stockpile and processing areas will be in the southwest comer of the site. The pit will be sloped <br /> to a 3H:1 V 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 inside <br /> of the processing area as shown on the Mining Map. This area, as well as the stockpile and <br /> processing areas, will be prepped by removing and stockpiling topsoil for later reclamation. <br /> Mined and processed aggregate will be stored surrounding the portable processing plant(s). <br /> Topsoil and overburden berms will be stored around the perimeter of the permit boundary for <br /> later use in reclamation. <br /> 2. Mining Timetable <br /> The construction project is anticipated to February 2023, depending on weather. Mining is <br /> planned to finish by Fall 2023. <br /> 3. 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 /> within an earthen berm that will have a capacity of at least 110%of the volume of the tanks to <br /> be kept onsite. No permanent structures will be built within the permit area as part of this <br /> operation. Water will be used to control dust on site. Water for this operation will be purchased <br /> from an offsite source in Colorado City and trucked to the site It is estimated that the operation <br />
