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 are shown on Map 2.04.7-1A. See 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 New Horizon. When Phase 3 bond release on the majority of the New Horizon <br /> #1 Mine area was done in 2001, this spring was abandoned for monitoring but it still flows. Spoil <br /> Spring 1 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 which has not yet attained Phase 3 bond release. This location was adjusted slightly on Map <br /> 2.04.7-1 A 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 /> January 2017 (TR-77) 2.05.6(3)-33 <br />
