Existing fences border most of the site. No problems are expected with vandalism. It is <br /> extremely unlikely that any toxic or acid-producing materials will be encountered during the <br /> mining operation since the past mining shows that the material is alluvial in nature. However, in <br /> the event that such materials are encountered, they will be covered with subsoil and topsoil from <br /> the stockpiles to the same depths outlined in the reclamation plan and no more mining will occur <br /> in this area. <br /> The operator commits to clearly marking the permit boundary with stakes surveyed on site. <br /> Speed limits and other traffic control signs can be found throughout the site and around the <br /> operation area. <br /> The site will use all existing roads to haul the product to its final destination. Routt County <br /> Roads 129, 62, and 62A service the site and are paved with gravel shoulders and no sidewalks. <br /> Most of the material produced at the site will be transported east on CR-62 to CR-129 and then <br /> either north or south. Trucks are restricted on CR-62 north of CR-62A except for local <br /> deliveries. A maximum average of 122 trips per day occurred in 1999. This haulage is not <br /> expected to be excepl-led. Peak months of haulage are May through September. <br /> Water is used brought on site and applied on a continual basis to control dust on haul roads and <br /> within the mine area. <br /> The Fetcher Vale Pit will use a main sediment sump to trap all runoff from a 100 year 24 hour <br /> rain event. This sediment settling/storm water pond is in the southeastern extent of the site north <br /> of CR-62A adjacent to the Staging Area. A gravel embankment is used to allow infiltration of <br /> collected rain water within the sump within 72 hours following a storm water collection event. <br /> No discharge permit is needed because no water will be leaving the site. Additional calculations <br /> for the storm water/sediment settling pond is presented in Exhibit G- Water Information. <br /> A two foot tall windrow will be maintained on the northeastern portion of the pit where the pit <br /> daylights to ensure that all stormwater maintains on site during storm events. The windrow will <br /> be graded flat near the end of final reclamation. <br /> Fetcher Vale Pit a <br /> May 2018 D-6 <br />
