Jther areas orprocedures wherepotentiadspillscan occur <br />Other potential pollutant sources related to mining activity includes: <br />• Outdoor milling or processing activities - Milling of mined ore from the <br />Sunday Mines is conducted at Denison's White Mesa mill near Blanding, <br />Utah. Therefore, processing activities are not conducted at the Sunday Mines. <br />• Tailings ponds - Milling of ore is not conducted at the Sunday Mines, <br />therefore, tailings from mill processes are not generated at these locations. <br />• Crushing facilities or processing activities - Ore is not crushed at the Sunday <br />Mines. <br />• Historic mine drainage - Mine drainage resulting from the discharge of mine <br />water to the surface has not been necessary at Sunday Mines. Some water can <br />be encountered during underground mining activity, but routing of waters to <br />inactive underground areas and the use of water for mining purposes <br />eliminates the need to dewater the mine and discharge water to the surface. <br />These mines have historically been non-discharging facilities. <br />• Trace metal - Consideration of trace metal migration from the waste rock is <br />appropriately addressed within the context of the Mining Permits issues by <br />Colorado's Division of Reclamation, Mining and Safety. As such, necessary <br />revision(s) to stormwater management practices relative to trace metal <br />consideration can be prompted by those permit reviews and incorporated into <br />this plan as necessary. Transport of trace metals has not occurred at this site. <br />No other potential pollutant sources are identified at this time. <br />See further discussion of appropriate BMPs in Section 3.c) and Appendix C. <br />c) BMPs for Stormwater Pollution Prevention (§I.C.3.c): <br />The following sections describe the BMPs selected for implementation on this site.
