quality standards or specific circumstances that would require permits. No CPDHE storm -water <br />permit is required for this operation as the new area of disturbance is less than the area <br />required for permitting. There are currently no reagents or chemicals used on the site that <br />would be anticipated to be consumed or reacted leaving any hazardous concentrations of any <br />designated chemicals. In the event that any hazardous materials might be imported or <br />generated in the future, they will be handled according to applicable regulatory standards <br />including those set by the EPA, CDPHE, and Department of Transportation (DOT) as related to <br />transport of solid waste. No other licenses are known to be necessary for the current <br />operation. <br />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." There are no designated chemicals currently used in the mine or mining <br />process. In the event that such chemicals might be brought onto the site, or compounds that <br />might be on site in quantities considered to be greater than de- minimus or above standards per <br />Federal regulations, material safety data sheets (MSDS) and handling procedures would be <br />developed to provide the proper safety and protections to personnel and the environment. <br />6 DESIGNATED CHEMICAL HANDLING <br />There are no designated chemicals used in the mine or mining process, but the following <br />describes the procedures for the handling and disposal of designated chemicals and toxic <br />materials within the permit area if such chemicals should ever be used. The goal of the <br />procedures would be to protect human health and to prevent unauthorized release of <br />pollutants into the environment. The safe handling of designated chemicals (and even non - <br />designated chemicals) would be accomplished via operator training, secure storage, and <br />routine maintenance of equipment and facilities. Proper materials and equipment would be <br />kept on site for emergencies in order to contain and clean up any spills that might occur with <br />spill cleanup kits being available. Equipment might include fifty -five gallon drums, liners, and <br />plastic sheeting, along with items that might be specific for that chemical or compound. Any <br />designated chemicals that might be used in the extractive metallurgical process would be <br />stored on site within an Environmental Protective Facility (EPF) and within secondary <br />confinement as appropriate. The amount of designated chemicals stored on site would be <br />listed, and the chemical would be stored and handled in accordance with training and <br />information contained with the MSDS. If, at the time of reclamation phase, the chemical would <br />3 <br />
