(1)(c) <br /> There is no uranium,and there will be no acid mine drainage or designated chemicals at this site. <br /> (1)(e) <br /> There are currently impoundments,waste rock piles and other material stockpiles. The proposed mining <br /> and reclamation plans will create a site which provides net improvement to human health, property and <br /> the environment. <br /> (2) <br /> The mining and reclamation maps in Exhibit E contain the information required for the EPP maps under <br /> this rule. All applicable items,areas and features referred to in this EPP are shown on the maps. <br /> (4) <br /> Please see the list of other required permits and licenses contained in Exhibit F. <br /> (6) <br /> The procedures for disposal,detoxification,and stabilization of toxic or acid-forming materials,the <br /> adequate reclamation practices, measures to prevent releases to the environment, and prevent <br /> discharges of acid mine drainage are all described in Exhibits C and D. <br /> The waste rock materials to be handled in this operation have been analyzed;the nature and constituent <br /> concentrations were considered in formulating the mining plan. The waste rock currently resides in a dry <br /> location,will be sorted as dry material,and once sorted, depending on resultant levels of mineralization, <br /> will be either exported from the site or disposed of onsite as dry material. No solutions will be created. <br /> The crushing,screening,and sorting operation will produce a 50mm x 10mm sorted product <br /> (mineralized,for offsite processing), a 50mmx10mm demineralized inert waste product,a mineralized <br /> product screened to pass through an opening size ranging from 6 mm to 10 mm (depending on moisture <br /> content),and containing crusher fines(less than 3 mm particle size) screened from crushed whole rock <br /> and including rock particles up to 10mm screen size.Crusher fines material will be transferred to the mill <br /> for off-site processing to minimize the amount remaining on-site. MineWater will limit the accumulation <br /> of the crusher-fines material on site to 2,000 CY or less until DRMS approves a subsequent method of <br /> on-site stabilization or other handling procedures. <br /> Sampling of crusher fines stockpiled on-site, per the attached Sampling Plan,will be undertaken at a high <br /> frequency, initially at one composited sample(reflecting representative sampling of each 500 CY) per <br /> 2,000 CY,and sampled for Acid Base Accounting, and leachability test-work at a minimum EPA Method <br /> 1312(modified Synthetic Precipitation Leachate Procedure or SPLP to which dissolved zinc analysis of <br /> the SPLP leachate is added to the analytical method), and if any issues are discovered from the ABA and <br /> SPLP+Zn,then further analysis with Meteoric Water Mobility Testing or MWMT will be undertaken). <br /> If ABA testing indicates that the crusher fines are acid-forming,then chemical amendment of the fines <br /> will be proposed in a technical revision to the Division and upon approval by the Division such chemical <br /> amendment will be conducted real-time such that the piles are amended as they form (presumptively <br />
