Water Quality <br />The Colowyo Coal Company discharges to three drainages flowing north to the Yampa River. The <br />company's mining operations dischazge to Wilson Creek from three outfalls, Taylor Creek from <br />three outfalls, and to Good Spring Creek from four outfalls. <br />• All of the Colowyo mine dischazges are to waters in the same regulated stream segment. Wilson <br />Creek, Taylor Creek and Good Spring Creek aze part of Segment 3e and are classified as Aquatic <br />Life Warm 2, Recreation Ib, Water Supply and Agriculture. It is designated use protected and does <br />not require antidegradation review. Segment 3e has numeric physical, inorganic, and metals water <br />quality stream standards. The stream standards for this segment are identified below on Table 3 In- <br />Stream Standards for Stream Segment COLCLY03e. Standards for metals are generally shown in <br />the regulations as Table Value Standards (TVS). Table Value Standards are shown on Table 4, Site- <br />. Specific Metals Water Quality Standazds for the Colowyo Mine Dischazges to Segment 03e and are <br />derived from equations that depend on the mean hardness of the creek at the discharge location. <br /> <br />WQA 3 Revised 1/24/2005 <br />
