All such materials, after use, will be promptly discarded in an approved manner as stated <br />in the product MSDS sheet. The materials listed above are stored at the mine site at all <br />times and can be replenished within 24 hours if supplies are depleted. Adequate supplies <br />of the material will be stockpiled to handle most teak or spill situations. <br />The following plan should be followed in case of a significant leak or spill of underground <br />emulsion oil from the longwall hydraulic system. Contaminated water should be contained <br />in the underground sump. ECO Recovery Systems Inc. will be contacted to mobilize the <br />necessary equipment for removal of oil from sump water discharge. NALCO ENACT <br />7783 (Aluminum Sulfate) can be used to flocculate oil. The flocculated oil can be <br />removed with a combination of centrifuge extraction followed by filtration of centrifuge <br />effluent at 10 microns. This can be done utilizing the ECO Rfxovery Systems Inc. leased <br />equipment for decontaminating the sump water. Using a chemical injection pump, inject <br />ENACT Aluminum Sulfate at 83 ppm into the treatment stream. This will effectively <br />flocculate the emulsion oil out of the contaminated water. Then use the ECO Recovery <br />Systems Inc. centrifugation and filtration trailers for final affluent (See Appendix C). <br />United Laboratories Product 655 "Zymeflow" will also be used as an emulsion oil digester <br />for small leaks and spills on site. This biodegradable enzyme has been shown to break <br />down emulsion oil out of sump water and is non-toxic to aquatic life. This product has <br />been included in Deserado Mine's NPDES discharge permit for use on the mine site. <br />Oil and fuel spills containing oil residue and/or fuels in diked areas will not be allowed to <br />accumulate and will be promptly removed and disposed of. <br />I. MANAGEMENT APPROVAL <br />This Spill Prevention, Control and Countermeasure Plan (SPCC) for the Deserado <br />Mine site will be implemented as described herein. <br />Q~. ~~~ <br />Alan J. illazd Mine Manager <br />Blue Mountain Energy - [nc. <br />June 10, 1997 <br />9 <br />
