• <br /> • <br /> In addition to the areas that are tributary to the process water system, there are <br /> additional upland areas totalling 1,230 acres in the Eagle River basin where canals intercept <br /> and bypass unaffected runoff and discharge to the East Fork of the Eagle River at the <br /> property boundary. Portions, but not all, of this interceptor system are applicable under <br /> this SWMP. <br /> The Climax Mine is implementing measures for the reclamation of portions of the <br /> mine site in the Arkansas basin and the Eagle River basin which have historically been <br /> collected and treated in the process water system. Part of the reclamation effort is to <br /> provide a positive separation between surface storm water and process water flows so <br /> that most of the reclamation areas can be treated and permitted under a storm water <br /> permit in lieu of the process water permit. Such areas are addressed and are applicable <br /> under this SWMP. The total area that can be potentially transferred to storm water <br /> management by this method (near term) is about 60 acres in the Arkansas River basin and <br /> 170 acres in the Eagle River basin. Other areas may also be transferred in this manner in <br /> • future years and reclamation efforts. <br /> The Climax Mine activities date back to about 1918 when two molybdenum mining <br /> companies operated small mines at the headwaters of Tenmile Creek. The Climax Mine <br /> has grown and evolved since that time to the expanse described above. Since the 1970's <br /> the mine has produced molybdenum concentrates at various production rates varying from <br /> no production during stand-by periods to as high as 50,000 tons per day (mined ore). <br /> Currently the site is not producing and is in a stand-by, care and maintenance mode, but <br /> will be operated as a producing mine in the future as market conditions dictate. There are <br /> no current plans to re-envelope the storm water areas described in this plan back to <br /> process water areas after the reclamation is completed. <br /> The scope of this SWMP is therefore the implementation of Best Management <br /> Practices for reclamation sites in the Arkansas River and Eagle River basins that have <br /> traditionally been within the Process Water area but are now to be transferred to storm <br /> water areas. Reclamation bond release in the future may further remove these areas to an <br /> "unclassified" designation, not subject to either the Storm Water Program or 40 CFR Part <br /> 440 Effluent Guidelines. The process water areas shown on Figure 1 are subject to <br />
