i <br />9.0 SPILL MITIGATION AND REPORTING <br />9.1 Clean-uo and Detoxification <br />The emergency response program will include specific training <br />in clean-up and detoxification for selected employees. Employees <br />specially trained will be onsite 24 hrs/day, 7 days/week. In the <br />event of a spill these employees will be immediately dispatched to <br />the site to assist in clean-up and detoxification efforts. <br />Appropriate equipment will be available to detoxify solutions and <br />to transport any spilled material for ultimate disposal in accordance <br />with applicable laws and regulations. In addition to clean up <br />equipment, portable instrumentation will be'available Ito detect and <br />measure HCN gas, as well as cyanide which may have entered any water <br />courses. <br />In the event of a potentially hazardous material spill the plan <br />will be to contain, detoxify, (if necessary) and clean up. <br />Detoxifying agents for cyanide. and acids will be kept available at <br />the mine for use. <br />Clean-up team personnel will be trained in the proper <br />detoxification procedures for each type of material. Aicids used on <br />site can be neutralized with the addition of lime and water. Lime <br />can be added directly to the spill area in the powder form. <br />For cyanide detoxification, one of two methods will be used, <br />either hydrogen peroxide detoxification or alkaline chlorination <br />detoxification. Both work effectively as detoxifying agents. <br />If hydrogen peroxide is used, it will be available in liquid <br />form. Hydrogen peroxide requires no pH control and wiyl naturally <br />break down into water and oxygen. Excess amounts pose do threat to <br />the environment. Liquid hydrogen peroxide can be added directly to <br />a spill until cyanide levels reach acceptable limits. Because <br />hydrogen peroxide breaks down, it has a limited shelf life.
