ANNUAL CERTIFICATION OF IMPOUNDMENT <br />WEST RIDGE CHECK DAM STRUCTURES <br />September 25, 2002 <br />I, the undersigned, certify that the West Ridge Check Dam Structures, numbers 9-21, based on <br />observations made during visual inspection on September 25, 2002, are structurally sound and <br />capable of performing the velocity check function that they were designed for. The features do <br />impound water and have storage capacity to capture sediment from surface wat n These <br />structures will, by design, eventually fill with sediment and cease to impound w er. The st ctures <br />were built, and reconstructed, at a minimum, to meet design criteria outline in the Ed to Mine <br />Permit (#C-80-001). <br />Colorado P.E. #35009 <br />
