Impacts to Receiving Waters <br />Since these spoil springs were never present in the pre -mine landscape, their impact to the quality <br />of the receiving waters must be addressed. As described earlier, a spoil spring will develop on the <br />northwestern part of the New Horizon #2 mine area where the single lowest point occurs along the <br />lowwall crest, which can be seen on Map 2.04.7-1-A. This is shown as Spoil Spring #4. <br />The Spoil Spring monitoring locations and NPDES point 001 are shown on Map 2.04.7-1A. See <br />descriptions below. <br />Spoil Spring #1 is shown as SS#1 and is located approximately 2100 feet northeast of the NW <br />corner of the New Horizon #2 permit area. This spring has been monitored since 1984 by Peabody <br />and then later by WFC. When Phase 3 bond release on the majority of the New Horizon #1 Mine <br />area was done in 2001, this spring was abandoned for monitoring but it still flows. Spoil Spring 1 <br />discharges into Tuttle Draw a short distance downstream. <br />Spoil Spring #2 is located approximately 50 yards downhill of Spoil Spring #1. This spring has been <br />monitored since 1986 by Peabody and was shortly thereafter abandoned since it did not flow. It <br />was basically a seep area with cattails below Spoil Spring #1. When Phase 3 bond release on the <br />majority of the New Horizon #1 Mine area was done in 2001, this spring was abandoned for <br />monitoring and does not still flow. <br />Spoil Spring #3 is located on the Rice Tract, which is the sole remaining portion of the New Horizon <br />#1 Mine whichhas not yet attained Phase 3 bond release. This location was adjusted slightly on Map <br />2.04.7-1A for better accuracy. This spring no longer flows and was abandoned in 2001, when <br />Phase 2 was granted for the Rice tract. <br />Spoil Spring #4 is located in the northwest corner of the New Horizon #2 Mine and is the predicted <br />location of the spoil spring for this mine area once the spoil becomes saturated. As of August of <br />2010, mining has not even reached this point yet and the spoil behind it is not yet saturated. <br />NPDES discharge point #1 was downstream of Spoil Spring #1 and basically collected all the spoil <br />water that was leaving the overburden in the New Horizon #1 Mine area. This site was also <br />abandoned when Phase 3 bond release on the majority of the New Horizon #1 Mine area was <br />completed in 2001. <br />The predicted Spoil Spring 4 from the New Horizon #2 Mine will discharge into the minor <br />tributary to Tuttle Draw, located immediately south of the western edge of the mine area. <br />This tributary enters Tuttle Draw less than 1 mile downstream. Tuttle Draw enters the <br />San Miguel River approximately 2 miles to the southwest. <br />July 2016 (TR -74) 2.05.6(3)-33 <br />
