JD-8 Mine Environmental Protection Plan <br /> • to be taken to prevent any unauthorized release of pollutants to the environment. Include adequate <br /> reclamation and closure practices for such designated chemicals,toxic or acid-forming materials <br /> and how unauthorized discharge of acid mine drainage will be prevented. <br /> b) Submit a narrative description or plan that: <br /> i. Describes how all designated chemicals used in the extractive metallurgical process will <br /> be handled during active mining operations and during periods of Temporary Cessation <br /> and disposed or detoxified at the conclusion of operations so as to comply with all <br /> applicable environmental protection and reclamation standards and regulations; <br /> ii. Describes how materials that have the potential to produce acid mine drainage or are <br /> toxic or acid-forming will be handled to ensure that the affected lands will be reclaimed <br /> and returned to the approved post-mining land use;and <br /> iii. Describes how the Operator/Applicant will prevent adverse off site impacts during <br /> periods of active mine site operations and periods of Temporary Cessation. <br /> c) Based upon acceptable site-specific analyses of site construction materials,waste rock,ore, <br /> product stockpiles,and mill tailings,if applicable,provide an assessment of the nature, <br /> concentrations and expected fate of potential acid mine drainage-forming materials. <br /> 5.2 Types,Quantities,and Concentrations of Designated Chemicals <br /> For the purpose of the EPP,designated chemicals have been grouped into two general categories: <br /> chemicals that are derived offsite and used onsite for mining operations(such as diesel fuel and <br /> lubricants)and native rock materials derived onsite that are mined as waste rock or ore.Native rocks that <br /> • are not mined are not considered designated chemicals for the purpose of this EPP. <br /> 5.2.1 Designated Chemicals Originating Offsite <br /> The designated chemicals that are derived offsite and used on site for mining operations include diesel <br /> fuel and lubricants. During the operation of the mine, less than 1,320 gallons of fuel and oils will be <br /> stored on the property in an existing above-ground fuel tank.The fuel tank will be located within a <br /> bermed and lined catchment.The oils stored on the surface will be located within a bermed and lined <br /> catchment. Because the volume of fuel and oils stored onsite will be less than the regulatory threshold of <br /> 1,320 gallons, a spill containment plan is not required(40 CFR 112, U.S.EPA Spill Prevention,Control, <br /> and Countermeasure Regulation). <br /> Materials Safety Data Sheets(MSDSs)for diesel fuel,rock drill oil,motor oil,and hydraulic oil are <br /> provided in Attachment 2. <br /> 5.2.2 Designated Chemicals Originating Onsite <br /> Uranium and vanadium ore and the accompanying waste rock will be mined from the underground <br /> workings. The ore is derived primarily from the Salt Wash Member of the Morrison Formation,which <br /> consists of interbedded fine-grained sandstone and mudstone.The uranium and vanadium mineralization <br /> occurs in bands that range in thickness from a few inches to more than six feet,with an average ore <br /> thickness of 2.5 to 3.5 feet.The mining plan is provided in Exhibit D of the JD-8 Mine Permit. <br /> The mineralization at JD-8 is similar to the rest of the Uravan Mineral District. Uranium occurs primarily <br /> in the form of uraninite(pitchblende variety UO2)with traces of coffinite(USiOaOH)filling in the pore <br /> • space between individual sand grains(Peters,2011).The uraninite(pitchblende)occurs as a more <br /> 13 <br />
