5.1.1.8 Conoco Light Oil (or alternatively Total Petroleum Light Cycle Oil) <br />• <br />Not currently (May 2004) used onsite due to standby status of the mine. <br />Description: Conoco Light OiI is a milling reagent used in flotation processes. <br />Location: Oil tank house north of the Mill Building. <br />Spill Potential: Very low inside oil tank house; moderate at fill station inside Regrind Tunnel <br />where it's off-loaded. The fill station is located adjacent to the reagent vault. The fill station has <br />been decommissioned. <br />Potential Volume Spilled: 16,000 gallons if full tank spilled in oil tank house. Currently (May <br />2004) only a small quantity of residual material exists in the tank. <br />Prevention and Control: The 16,000-gallon pine oil tank is located in a large concrete vault <br />(82,000 gal capacity) below grade in the oil tank house. This vault easily could contain the entire <br />stored volume of Conoco Light Oil. A floor drain connects with the mill process line should a <br />spill occur. Spills of Conoco Light Oil at the unloading hose in the Regrind Tunnel can be <br />prevented by operator caze and making sure connections aze secure between tanker and hose <br />coupling. <br />• Countermeasures: Small spills in the oil tank house can be cleaned up with floor dry and <br />shovels. Lazger spills will require sorbent booms and floor dry. In the Regrind Tunnel, small <br />spills wilt be absorbed by floor dust and loose material comprising the road surface. Oi] stained <br />dust should be scooped up with a shovel and disposed of properly. Lazger spills will be <br />controlled by sorbent booms or dikes. Contact the Environmental Department for proper disposal <br />methods (most likely the Climax landfill). <br />Nearest Clean-up Equipment: A spill kit is located in the west end of the mill building. <br />Visual Inspections and Integrity Testing: The oil tank house and the hose and coupling in the <br />Regrind Tunnel aze checked daily during mill operations; monthly otherwise, <br />Reporting: All spills of Conoco Light Oil which threaten waters of the State of Colorado aze <br />subject to the requirements of Sections 4.2, 4.3, and 4.4 of this SPCC Plan. All spills of 5 <br />gallons or more should be reported to the Environrental Department by using the "Spill Incident <br />Report" form given in Appendix 1. <br />Conformance with Applicable Requirements: Since no Conoco light oil is in use [at the time <br />of this writing (May 2004)] the facility is in conformance with applicable regulatory <br />requirements. <br />LJ <br />21 <br />
