Climax Molybdenum Company HENDERSON MINE & MILL SWMP <br />Empire & Parshall, CO December, 2011 <br />Page 2-2 <br />building at PC-2/PC-3 Transfer, a snow shed, trestles crossing wetlands at Con3 and Con9, <br />an elevated trestle at the Mill, and over 20,000 feet of elevated conveyor housing and <br />appurtenances. The route of the conveyor begins by following Henderson’s former train <br />haulage system—passing 1.1 miles overland across U.S. Forest Service lands followed by <br />approximately 4 miles of private land owned by Climax. The surface right-of-way, an <br />associated building (PC-2), and a reclaimed yard area near the tunnel portal are also <br />addressed in this plan. <br />2.2 Areas Subject to Effluent Limitations Guidelines <br />As identified in the previous section, the majority of storm water from disturbed areas <br />associated with the Henderson Operations is discharged under the authority of process water <br />discharge permits. The discharges are subject to effluent limitations for the Ore Mining and <br />Dressing Point Source Category, Copper, Lead, Zinc, Gold, Silver, and Molybdenum Ores <br />Subcategory, which are found in the Code of Federal Regulations 40 CFR 440 Subpart J. <br />2.3 Site Plan <br />Facility diagrams and map detailing the location of the facility and surrounding topography <br />are provided in Appendix A and include the following. <br />Figure Title Purpose <br />1 <br />Mine, Mill & <br />Conveyor Location <br />Map <br />Illustrates the locations of the Mine, Mill, Urad and Haulage <br />System. This map also includes the general drainage patterns and <br />flow directions and the locations of outfalls, potential storm water <br />pollutant sources, material storage areas that are along portions of <br />the haulage system that are not covered in other maps, areas of soil <br />disturbance, location of surface water bodies located in or next to <br />the facility, identification of existing structural control measures <br />and location of impervious structures. <br />2 Mine Storm Water <br />Management Map <br />Illustrates the location of storm water permit areas associated with <br />the Mine as well as general drainage patterns and flow directions <br />and the locations of outfalls, potential storm water pollutant <br />sources, material storage areas that are along portions of the <br />haulage system that are not covered in other maps, areas of soil <br />disturbance, location of surface water bodies located in or next to <br />the facility, identification of existing structural control measures <br />and location of impervious structures. <br /> <br /> <br /> <br />3 <br /> <br /> <br />Mill Storm Water <br />Management Map <br />Illustrates the boundaries of storm water permit areas associated <br />with the Mill as well as general drainage patterns and flow <br />directions and the locations of outfalls, potential storm water <br />pollutant sources, material storage areas that are along portions of <br />the haulage system that are not covered in other maps, areas of soil <br />disturbance, location of surface water bodies located in or next to <br />the facility, identification of existing structural control measures <br />and location of impervious structures. <br /> <br />4 <br />Mill Storm Water <br />Management Map, <br />Upper <br />Conveyor/Access <br />Road Area <br />Expanded inset on Figure 1 detailing the area surrounding the <br />upper conveyor and access road area. This map includes much of <br />the same content as described above in Figure 3.
