5 DESIGNATED CHEMICAL EVALUATION <br />According to the DRMS Hard Rock /Metal Mining Rule 1 Designated chemicals are defined as: <br />toxic or acidic chemicals used within the permit area in extractive metallurgical processing, the <br />use of which at certain concentrations, represents a potential threat to human health, property <br />or the environment. The flotation process at the mill consumes reagents at very low <br />concentrations, and no cyanide or mercury is used as a part of that process. There are no <br />designated chemicals used in the mine or mining process. It has been noted that DRMS <br />considers liquid fuel products as designated chemicals and the site uses diesel as fuel and oils as <br />lubricants. Table 1 lists the chemicals that are believed to fall in this category, and contains the <br />names, use, concentrations, quantity, location, and fate of the designated chemicals and <br />hydrocarbons. Compounds that might be on site in quantities considered to be de- minimus <br />per Federal Regulations are not included. Material safety data sheets (MSDS) are included as <br />Attachment 1. <br />6 DESIGNATED CHEMICAL HANDLING <br />The following describes the procedures for the handling and disposal of designated chemicals <br />and toxic materials within the permit area at the Lucky Strike Mine as well as measures to <br />prevent unauthorized release of pollutants into the environment. There are no designated <br />chemicals used in the mine or mining process. Reclamation of the mine will be carried out as <br />described in the reclamation plan submitted and approved in the M- 1982 -020 permit. <br />As described in Section 7 of this EPP there are three environmental protection facilities (EPF) in <br />place to prevent unauthorized release of any designated chemicals used in the processing <br />operation ( Onsite Chemical Storage Map). The safe handling of designated chemicals (and non - <br />designated chemicals) is accomplished via operator training, secure storage, and routine <br />maintenance of equipment. Materials and equipment are kept on site for emergencies in order <br />to contain and clean up any spills that might occur. Spill cleanup kits are located in the fuel <br />storage building, generator shed, and mill building. Fifty -five gallon drums, liners, and plastic <br />sheeting are kept on site for storing and removing any designated chemical spillage and <br />contaminated soil in the event a spill might occur. Based on the maximum sized reagent <br />container transported to or kept on site, the largest quantity of designated chemicals spilled <br />would be 50 gallons. <br />Designated chemicals used in the extractive metallurgical process and used during the active <br />mining process are stored on site within an EPF and within secondary confinement. The <br />amount of designated chemicals stored on site will not exceed the amounts listed in the Table <br />1. Operators will use and store designated chemicals according to training and information <br />contained with the MSDS. No designated chemicals will be disposed of onsite during active <br />operations. <br />3 <br />
