6.3.2 Exhibit C <br /> Mining Plan <br /> The 7.8-acre site will develop as a one phase mine. The mine will be used to extract borrow <br /> material for the Colorado Department of Transportation job that is located right at the pit site on <br /> Highway 50. Extraction will begin on the north side and proceed south and encompass <br /> approximately 2 acres of the permitted area. The remaining acreage will be used for staging and <br /> stockpiling of materials, along with the haul route to the project site. <br /> This will be a dry mine with. It is anticipated that the mining operation will be completed by <br /> September 2019. There is one soil type in the target mining area, Mussel-Bronell Complex with <br /> 2-15% slopes. Information regarding the soil type in the mining area is attached for review. <br /> Activities on the site will include the use of scrapers to remove the topsoil and any vegetation for <br /> stockpile and use during reclamation. This will be followed using an excavator to stockpile pit <br /> run. <br /> The target material on the site is borrow. There is approximately four feet of overburden on site <br /> with limited topsoil. All topsoil encountered will remain on site for reclamation purposes. <br /> Reclamation will occur once all mining has been completed. Mining will go to a depth of <br /> approximately 15 feet. <br /> The internal road onsite will be used for trucks to leave the site and enter Highway 50 for <br /> transportation of materials along the project site. <br /> No permanent structures will be necessary, except a portable sanitary facility. Water is not <br /> anticipated to be intercepted at the site. <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. The site is anticipated to be <br /> operational from May through September 2019. <br /> In the event noxious weeds appear, they will be mechanically removed as directed by the <br /> Fremont County Weed Management Director Nick Bankston. A Weed Control Plan can be <br /> developed as necessary. <br /> Fugitive dust will be controlled by posting vehicle speed limit signs at 10 miles per hour <br /> throughout the site and along 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 and <br /> haul it onsite for use. It is anticipated that approximately 10,000 gallons will be used daily for <br /> dust control. <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 surface <br />
