Mr. Peter Hays, DRMS <br />December 13, 2011 <br />2IPage <br />Sincerely, <br />Tim Haynes <br />Sr. Environmental Engineer <br />Climax Molybdenum Company <br />Henderson Operations <br />surface uncovered) and would have been even more susceptible to temperature swings. <br />(see Images # 1 — 3). <br />As of December 13th, the breach in the piping had been repaired by fusing a new section <br />of pipe into the void created by the contraction (Images #3 — 6). The section of piping <br />associated with this issue will be examined by a professional inspector to ensure pipe <br />integrity. Moving forward, Henderson is evaluating a more rigorous inspection protocol, <br />which may include qualitative inspection of welds associated with the TDL. To further <br />alleviate the stress of heat and cold cycles on the pipeline, Henderson plans to bury the <br />exposed TDL, which will help moderate temperature swings. <br />Henderson is also actively working to ensure that there are process control mechanisms <br />in place to help manage issues like this from a line pressure monitoring standpoint. This <br />would include automatically diverting flows if specified limits are exceeding, in regard to <br />line pressure, with the TDL. <br />If you have any additional questions or concerns, please feel free to contact me at 303 - 569 -3221, ext. <br />2284. <br />CC (via email only): <br />B.
