5.3 Climax Mine Tailing and Industrial Water System <br />• 5.3.1 Tailing and Industrial Water System in the Ten Mile Drainage <br />5.3.1.1 Tailing Delivery House (TDH) and East Tailing Delivery Line (ETDL) <br />During shutdown status, the TDH and ETDL are not in use for tailings delivery. As a <br />result, no work is cuttently planned in this area. If the ETDL were to rupture tailing fluids would <br />report to the process water system by overland flow. <br />Description; Main tailing delivery system from the Climax mill to the tailing ponds. Consists <br />of a concrete 42-inch diameter pipeline approximately five (5) miles long. <br />Location: ETDL extends from the mill through the TDH to the Robinson, Ten Mile, and <br />Mayflower tailing ponds. See Figure 1. <br />Spill Potenfial: High. <br />Potential Volume Spilled: Because the lines are checked regularly, spills aze likely to be less <br />than a few thousand gallons, unless the leak occurs beneath snow. <br />• Prevention and Control: Any spill from a ruptured line or in the TDH would be totally <br />contained in the tailing system drainage, and would have very little chance to by-pass the <br />treatment system. <br />Countermeasures: In the event of line rupture, tailing delivery will be shut down, the line <br />repaued, and spilled tailing will be cleaned up by use of mine equipment. <br />Location of Nearest Clean-up Equipment: Endloaders and trucks aze available throughout the <br />minesite; additional equipment (shovels, tailing line repair supplies, etc.) aze available in the <br />warehouse. <br />Visual Inspections and Integrity Testing: Visual checking occurs daily during operation of the <br />mill. During idle periods, the system is visually checked at least weekly. <br />Reporting: In the event that waters of the State of Colorado aze threatened by a spill from the <br />tailing delivery system, the notification procedure outlined in Sections 4.2, 4.3, and 4.4 will <br />apply. Any spill from the tailing delivery system should be documented on the "Spill and <br />Release Information Sheet" immediately (Appendix I), and given to the Environmental <br />Department. <br />Conformance with Applicable Requirements: At the time of this writing (May 2004) the <br />• ETDL is in conformance with applicable regulatory requirements. <br />47 <br />
