Night time activity will be restricted to emergency maintenance of the site or equipment. Any <br /> lighting needed for this activity will be minimal, and downcast. Security lighting on the office <br /> trailer will be flush. <br /> Portable toilets and bottled water will be provided for employees at the United/Norwood Pit to <br /> the north. All mining structures on site are shown on Map C-2. Upon reclamation, all portable <br /> equipment will be removed from the site. <br /> The entire site is surrounded by a perimeter fence and the permit boundary is marked with <br /> stakes surveyed on site. No problems are expected with vandalism. It is extremely unlikely that <br /> any toxic or acid-producing materials will be encountered during the mining operation since past <br /> mining shows that the material is alluvial in nature. However, in the event that such materials <br /> are encountered, they will be covered with overburden and topsoil from the stockpiles to a depth <br /> of at least two feet and no more mining will occur in this area. <br /> The site will use all existing roads to haul the product to its final destination. It is planned that <br /> the material may be used to re-surface existing roads, make concrete aggregate or provide new <br /> road base for any new roads within an economic distance to the site. <br /> The only hazardous material kept onsite will be the oils and diesel fuel of the mining equipment <br /> themselves. No fuel farm will be placed onsite. <br /> 4. Topsoil and Overburden Handling <br /> Topsoil depths are highly variable; it has been noted to be as thin as two inches in areas of the <br /> existing United/Norwood Pit and as thick as 60 inches in other areas. It is anticipated, based on <br /> taking the top two horizons of soil listed in the NRCS soil survey data for the site as topsoil, that <br /> 14 inches of soil can be stripped. Overburden depths are also variable and average over 50 <br /> inches, making up the remaining subsoil above the sand and gravel deposit. Topsoil and <br /> overburden will be used on site for reclamation of mined areas. Topsoil will be directly placed <br /> during reclamation. Stockpiles of these materials will be located to on the northeast of the site. <br /> Any topsoil or overburden stockpiles that is to be in place longer than 90 days will be re- <br /> vegetated to prevent wind erosion. <br /> Topsoil and overburden that is stockpiled will be placed in the facilities area on the northeast <br /> side of the site, as shown on Map C-2. United Companies commits to keeping enough material <br /> onsite to be able to reclaim the site. Estimates on reclamation required topsoil and overburden <br /> will be calculated on an ongoing basis as reclamation will occur concurrently with mining. <br /> Therefore, surplus material estimates will become readily apparent as mining and reclamation <br /> progresses from area to area. <br /> Topsoil stockpiled from the pit will be used in reclamation. Topsoil stockpile locations can be <br /> seen on Map C-2. This will reduce material moving as well as reduce the maximum area to be <br /> reclaimed. <br /> Skelton Pit C-3 <br /> January 2022 Lewicki 81 Associates <br />
