This includes the addition of <br />seven new impoundments (Area # 1 Pit, Thickner Underflow Holding Pond, Fish <br />Creek Tipple Waste Water Pond, and the series of four waste water treatment ponds at <br />Twentymile). Note that snow cover and recent sub-zero temperatures resulted in <br />limited visibility. Only Pond D and the four waste water treatment ponds were flowing <br />during the inspection. Following the first quarter 2006 inspection (which is anticipated <br />to have similar winter conditions), a detailed inspection of all sites will be performed <br />af=ter the spring thaw. Some dredging and maintenance is anticipated for the summer <br />of 2006 as noted in the reports. <br />This information is submitted in compliance with the Twentymile Coal Company <br />Permit 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 in <br />the state of Colorado (see next page). <br />Please contact me at (970) 870-2750 if you have any questions. <br />Sincerely, <br />~; ~ G <br />Brian A.
