5.1.1.5 Pine Oil <br />• <br />Not currently (May 2004) used onsite due to standby status of the mine. <br />Description: Pine oil 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. <br />Potential Volume Spilled: 16,000 gallons if full tank spilled in oil tank house. <br />Prevention and Control: The 16,000-gallon pine oil tank is located in a large concrete vault <br />82,000 ga] capacity) below grade in the oi] tank house. This vault easily could contain the entire <br />stored volume of pine oil. A floor drain connects with the mill process line should a spill occur. <br />Spills of pine oil at the unloading hose in the Regrind Tunnel can be prevented by operator care <br />and making sure connections aze secure between tanker and hose coupling. <br />Countermeasures: Small spills in the oil tank house can be cleaned up with floor dry and <br />shovels. Larger spills will require sorbent booms and floor dry. In the Regrind Tunnel, small <br />spills will be absorbed by floor dust and loose material comprising the road surface. Oil 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. <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 unloading hose and <br />coupling are checked daily during mill operation; they aze checked monthly when the facility is <br />not operating. The Pine Oil Tank was subjected to an integrity and "in-service inspection" by <br />Conam Inspection Inc. on July 18, 2000. Results of the inspection aze provided in Appendix 5. <br />Reporting: All spills of pine oil which threaten waters of the State of Colorado aze subject to <br />the requirements of Sections 4.2, 4.3, and 4.4 of this SPCC Plan. All spills of 5 gallons or more <br />should be reported to the Environmental Department by using the "Spill Incident Report" form <br />given in Appendix 1. <br />Conformance with Applicable Requirements: Since no pine oil is in use [at the time of this <br />writing {May 2004)] the facility is in conformance with applicable regulatory requirements. <br />However, Conam recommended that this tank should be cleaned and re-inspected prior to <br />putting it back in service (Conam Report, July 18, 2000). <br />• <br />18 <br />
