2.1. Equipment Mine Facilities and Operation <br /> The Spring Creek Pit will contain the following facilities and equipment. Approximate quantities of <br /> equipment is provided but this is subject to change as needed to complete mining and reclamation. <br /> Facilities: <br /> - Fuel Station —7000-gallon, diesel tank with secondary containment <br /> - Portable Wash Plant <br /> - Portable Crushing Unit <br /> - Gradation Screen/Conveyor(portable) <br /> - Portable Toilet <br /> - Mine Office (portable) <br /> - Stackers <br /> - Dumpster <br /> - Scale <br /> Equipment: <br /> - 1-3 Scrapers <br /> - 1 Dozer <br /> - 2 Loaders <br /> - 1 Grader <br /> - 1 Water Truck <br /> Only a loader and scale will be located on site full time, as most of the year the pit will not need to <br /> be running at full production. Equipment needed to produce material during the construction season <br /> will all be portable, and only present for the time needed to satisfy demands at the time. United will <br /> provide portable toilets and bottled water to employees on site during operations. <br /> 2.2. Blasting <br /> No blasting will take place at the Spring Creek Mine. <br /> 3. Topsoil and Overburden Handling <br /> The topsoil on site is estimated to be 12 inches thick, with approximately one to three feet of <br /> overburden underlying it. All overburden and topsoil will be stripped prior to mining for use in <br /> reclamation. Topsoil and overburden will be stockpiled separately and will be seeded if they are to <br /> be in place greater than 90 days. These stockpiles will be located in the previously mined areas of <br /> the Spring Creek pit. The general area to be used for stockpiling topsoil is shown in Map C-2. <br /> Overburden will be used to create a stormwater berm along the eastern perimeter of the property <br /> between the neighboring gravel pit, as shown in Map C-2.The remaining overburden will be used <br /> during reclamation to backfill the slopes from a 21-1:1V slope to a 3H:1V slope. Topsoil will be <br /> spread across the property in an even layer during reclamation. <br /> Spring Creek Pit <br /> September 2021 D-4 Lewicki&Associates <br />
