Spring N5. This spring is located in the Cow Camp Creek drainage but, due to its <br />location <br />Ss unlikel <br />to be disturbed b <br />minin <br />Floe vas too low (0 <br />81 <br />m) in <br />Tune • <br />, y y <br />g. <br />. <br />gp <br />, <br />, <br />1995 to warrant a lab sample; however, an electrical conductivity (EC) of 6540 umho/cm was <br />measurable. This high EC val ve can be attributed to localized geochemical conditions and <br />not to mining impacts. <br />Spoil Springs N1 and 2. Both these spoil springs ase located above the NPDES 004 pond. <br />Spoil Sprlnq N1 is a large spring that flws directly into the pond, and Spoil Spring N2 <br />is a small spring creek in reclaimed land that flows adz scent to Spoil Spring N1. <br />Water quality and hydrograph data for Spoil 6pring N1 may be found in Appendix E. Aewiev <br />oP this hydrograph shows higher than normal floes this year. TDS valves have been <br />increasing since this spring began flowing. This is due primarily to an ever increasing <br />recharge area of upgradient spoils material as mining progresses. Spoil Spring M2 <br />exhibits an increasing EC trend. <br />Spoil Springs N3, 4, 5, 7 and S. These springs all exist in the wedge seam mining area in <br />the Little Grassy Creel basin. Spoil Spring N3 drains aut of an old mine pit, and <br />exhibits a relatively level EC trend. Spoil 3prinq N4 Ss a Sprlnq adj scent to Spoil • <br />Spring N3 and exhibits a decreasing TDS trend. Spoil Spring NS (also known as the PeCOCo <br />Pond) issues cut of another o16 mine pit north of spoil Spring M3. It displays a <br />decreasing EC trend. All these springs eventually floe into the Wedge Impoundment via <br />Little Grassy Creek. <br />Spoil Sprlnq N7 eX19t9 at the upper enQ of the Wedge I¢¢wundment. Its EC plot has no <br />discernable trend so far. <br />Spoil Spring NS is across the road from Spring k2 along the north permit boundary. It is <br />situated in a road ditch and apparently issues from prel aw area spoils to the aovtR. It <br />displays a decreasing EC trend. <br />Spoil Springs N6 and 10. These springs exist in the Wolf Creek spoils. Spoil Spring N6 <br />exhibits a decreasing TD9 trend. Spoil Spring N10 vas discovered in 1993. It exists <br />along the southwest edge of the Wolf Creek spoils (Spoil Spring N6 exists along the <br />northwest edge of the same spoils). In June of thi s year, it displayed an EC of 4030 <br />umho/®. • <br />14 <br />
