Soil will be stripped as required for mine activities and will be directly placed on final waste pile surfaces <br /> as they are constructed. Topsoil stockpiled on site will be placed in one of two designated areas. The first <br /> area is immediately uphill of the Mine Water Pond(Pond 41). This topsoil stockpile area will be used <br /> while the Revenue TSF is being built. Once the Revenue TSF at capacity,an area on the top of the <br /> Revenue TSF will be used to store topsoil, if needed. Topsoil will be imported over the life of the mine to <br /> satisfy the reclamation requirement of a minimum of 6 inches over the reclaimed areas. These <br /> calculations are described in detail in Exhibit E. Topsoil will be tested prior to being accepted for use on <br /> the site to ensure it is suitable for reclamation purposes and to confirm it is free of contamination that <br /> could impact the environment. <br /> 5.5 Fuel and Oil Storage Areas and Reagent Storage <br /> Diesel fuel is stored on site in two, 10,000 gallon steel tanks located near the Mill Portal as shown on <br /> Map C-la. Unleaded gasoline will also be stored on site in one, 1,000 gallon tank next to the diesel fuel <br /> storage. The diesel tanks will be used to supply fuel to the on-site mobile equipment and backup <br /> generators for the power outages, if needed. Secondary containment is provided for all petroleum <br /> products. A Spill Control, Containment,and Contingency (SPCC) Plan for storing and using petroleum <br /> products is in place and has been included in Appendix 1. <br /> Mill chemicals and reagents will be in the Reagent Room of the mill for use in the processing of ore. The <br /> handling, storage and disposal of these chemicals is addressed in Exhibit U and the Material Containment <br /> Plan included in Appendix 1. <br /> 5.6 Mine Equipment Storage and Shop Building <br /> Two equipment storage warehouses will be constructed on the surface and will be 50'x60'. One <br /> warehouse will be constructed on the east end of the property and another to the north of the admin <br /> building. Equipment will be serviced in the underground facilities immediately west of the mill. <br /> Additional underground equipment may be stored in the railyard located to the east of the admin building. <br /> The location of surface facilities is shown on Map C-la. <br /> 5.7 Personnel Facilities and Compressor Building <br /> There are two personnel facilities as part of the Revenue Mine. The first is the mine office/dry room <br /> located just outside the portal. It is a steel structure on a 6-inch concrete foundation. The second facility is <br /> the set of portable lineout trailers. These trailers are temporary structures and are each 40' x 40'. They do <br /> not have a foundation. Immediately south of the dry-room is a 50' x 20' building that houses the air <br /> compressors for the mine; it sits on a 6-inch concrete foundation. <br /> 5.8 Designated Parking and Storage Areas <br /> A gravel parking area is provided for employees and visitors just northwest and adjacent to <br /> the mine offices. Signs will be posted stating that visitors must check in at the mine office. See <br /> Map C-Ia for location. <br /> 5.9 Mine Access Roads <br /> Access to the Revenue Mine will be via the existing site access road that connects to County Road 26. A <br /> gate is in place on the south side of the bridge to restrict access to the mine site. In addition, a security <br /> building is located at the entrance as an added measure of security to manage traffic in and out of the <br /> mine. Signs also are posted at the entrance to discourage general public from entering the mine site. <br /> Revenue Mine <br /> Amendment 02 D-17 <br /> December 2021 <br />
