5.3.1.3 Mayflower Auxiliary Pump System Pipeline <br /> Description: This 12-inch pipeline transfers water 0.6 miles from the Clearwater Holding Pond <br /> back to the Mayflower Tailing Pond. <br /> Location: The 12-inch line runs from the Mayflower Pump Station to the Mayflower Tailing <br /> Pond. <br /> Spill Potential: Low. <br /> Potential Volume Spilled: Approximately 3000 gallons could be spilled and subsequently <br /> discharge to Ten Mile Creek if a major failure or rupture of the pipeline occurred. <br /> Prevention and Control: Sufficient containment volume exists in the Mayflower Tailing Pond <br /> and the Clearwater Holding Pond to capture a spill of 3000 gallons, thereby preventing flow to <br /> Ten Mile Creek. <br /> Countermeasures: In the event of a leak in the pipeline, water can be drained into the <br /> Clearwater Holding Pond and the water can be transferred to the Industrial Water System by <br /> means of the Mayflower Pumping System. <br /> Nearest Clean-up Equipment: System management as described above would preclude the use <br /> of spill clean-up equipment. <br /> Monitoring: The pipeline is visually checked daily when in operation. During idle periods, the <br /> pipeline is checked weekly. System alarms are telemetrically transmitted to the mill control <br /> room. <br /> Reporting: Any spills which threaten waters of the State of Colorado are subject to the <br /> reporting requirements outlined in Sections 4.2, 4.3, and 4.4 of this SPCC Plan. All spills should <br /> be documented on the "Spill Incident Report" form immediately (Appendix 1), and copies <br /> provided to the Environmental Coordinator. <br /> 41 <br />
