PART I <br />Page 7 <br />Permit No. COR-040p00 <br />B. STORMWATER MANAGEMENT PLAN -ACTIVE MINES (contJ <br />certification to the present; method of on~ite storage or disposal; materials management practices employed to <br />m~n;mbn contact of these materials with stormwater runoff between July 1, 1989 and the present; <br />b. A list of significant spills and significant leaks of toxic or hazardous pollutants that occurred at the facility from <br />throe years prior to permit certification to the presort; <br />c. For each mining site area that generates stormwater discharges with a reasonable potential for containing <br />pollutants, identification of the potential pollutants which arc likely to be presort in the s[ormwater discharges; <br />and <br />d. A summery of any existing discharge sampling data describing pollutants in the stotmwa[er discharges. <br />5. Starmweter Ouslity Controls <br />Each mining operation certified under by this permit shall develop a description of stormwater quality controls appropriate <br />for that site, aad implement such controls. The appropriatoress and priorities of controls in the plan shall reflect <br />identified potortial sources of pollutants at the mining site. The description of atormwater quality controls shall address <br />the following minimum components, including a schedule for implemorting such controls: <br />a. SWIVIP Administrator -The SWMP shall identify a specific individual or individuals within the mining <br />organization who is responsible for developing the SWMP and assisting the mine operator in its implementation, <br />maintenance, end revision. The activities and responsibieities of the administrator should address all aspects of <br />the facility's SWMP. <br />b. Risk Identification and Assessment - The SWMP shall assess the potential of pollutant sources (including source <br />of process water that might become mixed with stormwater) at the mine to contribute pollutants to stormwater <br />discharges associated with mining activity. Each of the following shall be evaluated for the reasonable potential <br />for contributing pollutants to runoff: <br />- loading and unloading operations; <br />- outdoor storage of chemicals or equipment; <br />- outdoor milling or processing activities; <br />- historic mine drainage; <br />- tailings ponds; <br />- cn~shing facilities or significant dust end particulate generating activities; <br />- on-site waste disposal practices; and <br />- stockpiles of overburdor, raw material, intermediate products, byproducts, finished products or waste <br />products; <br />Factors to consider include the toxicity of Ure material; quantity of chemicals used; amount of material processed; <br />the likelihood of contact with etormwater; and history of significant drainage, leaks or spills of toxic or hazardous <br />pollutants. In each rase where stormwater pollution potential exists, appropriate preventive measures must be <br />identified and implemorted. <br />c. Preventive Maintenanm -The SWMP shall ideatify a prevortive maintenance program. This program shall <br />involve maintenance of stormwater management devices (main[emnce of dikes separating mine drainage from <br />stormwater, cleaning oil/water separators, catch basins, etc.) as well as maintenance of equipment and systems <br />to prevent conditions Uut could cause breakdowns or failures resulting in discharges of pollutants to surface <br />waters. <br />d. Good $otuelceeping -The SWMP shall identify good housekeeping procedures that will be followed by the <br />mining operation. Goad housekeeping requires the maintenance of a clean, orderly facility. This part of the <br />r SWMP should address cleaning and maintenance schedules, trash disposal and collection practices, grounds <br />maintenance, etc. <br />
