<br />u <br />PART I <br />Page 7 <br />Permit No. COR-040000 <br />B. STORMWATER MANAGEMENT PLAN -ACTIVE 11iIIVFS (coot.) <br />ceriifiation to the presort; method of oa-site smogs or disposal; materials maaagemeat practices employed to <br />minimize contact of these materiels with sWrmwater runoff between July 1, 1989 and the prat; <br />b. A list of significant spills and siguificant leaks of toxic or hazardous pollutants that oavrred at the facility from <br />three years prior to permit certification to the present; <br />c. For each mining site area that gmetaW stormwater discharges with a reesoaabk potential for containing <br />pollututts, identification of the potential pollutants which are likely to be present is the stormwater discharges; <br />and <br />d. A summary of nay existing discharge sampling data describing pollutants is the stotmwater discharge. <br />5. Stormwater Quality Conlrois <br />Farb mining operation certified under by this permit shall develop a description of stormwater quality controls appropriate <br />for that site, and implement such controls. The appropriateness sad priorities of controls in the plan shag reflect <br />identified potential sources of pollutants at the mining site. The description of stormwater quality controls shall address <br />the following minimum wmpoaeats, including a schedule for implementing such coatrois: <br />a. SWMP 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 is its implemrntation, <br />tnaiateaaace, and revision. The activities and responsibilities of the m~niatnstor should address all aspects of <br />the ficifity's SWMP. <br />b. Risk IderttRitatitw and Assesvnent - The SWMP shall assess the potential of pollutant sources (inchrding source <br />of process water thu might become mixed with sWrmwater) at the mine to contribute pollutants to siormwatez <br />discharges associated with mining activity. Each of the fallowing shag be ewluated for tha trasoaable potential <br />for contributing pollutants to rmoff: <br />- loading and unloading operations; <br />- outdoor storage of chemials or equipment; <br />- outdoor milling or proce4siag activide; <br />- historic mine drainage; <br />- tailings ponds; <br />- crushing facilities or significant dust and particulate gorerating activities; <br />- on-site waste disposal pnetices; and <br />- stockpiles of overburden, raw material, intermediate prodwts, byproducts, fiaisbed products or waste <br />products: <br />Factors to consider include the toxicity of the material; quantity of chemicals used; amount of material processed: <br />the likelihood of contact wiW stormwater, end history of significant drainage, leaks or spills of toxic or hazardous <br />pollutants, In each case where stormwater pollution poteatia) exists, appropriate ptevortive measure must be <br />identified and implemented. <br />c. Preventive Maintenance -The SWMP shall identify a prevrntive maintenance program. 'Ibis program shall <br />involve maintenance of stormwater auaagemeat devices (maintenance of dikes separating mine drainage from <br />smrmwater, cleaning oil/water separators, catch basins, eteJ as well as maiuteawce of equipment and systems <br />to prevent coaditiaas that could preu breakdowns or failures resulting in discharges of pollutants to surfirce <br />voters. <br />d, Good Hotsekttpirtg -The SWMP shall identify good housekeeping procedures flat will be followed by the <br />mining operation. Good housekeeping requires the maintenance of a clean, orderly facility. This part of the <br />SWMP should address cleaning and maintenance schedules, trash disposal and collection practice, grounds <br />maintenance. etc. <br />
