The only sites <br />flowing included 85 Pond D, 63 Pond B, the four waste water treatment ponds (CDPS <br />sites 300I and 300E), and Site 62, Fish Creek Tipple (FCT). <br />Some short circuiting was observed at the 62 FCT weir, however flows can still be <br />accurately measured via a culvert located between sedimentation Pond E and the site <br />62 weir. TCC will be replacing the weir at this location. Flumes and weirs at all other <br />discharge ponds appeared functional. Standard vegetation cleazance and minor <br />maintenance will be conducted as necessary. <br />This information is submitted in compliance with Twentymile Coal Company Permit <br />C-82-056 and Rule 4.05.6(13). The inspections were conducted by a qualified <br />individual under the direction of Michael Ludlow, a registered Professional Engineer <br />in the state of Colorado. <br />Please contact me directly at (970) 870-2750 if you have any questions. <br />Sincerely, <br />%, ,, <br />Brian A.
