The NOA required revisions to four procedural areas (items) within your Ruby Pipeline’s Operations and Maintenance (O&M) Manual. By letter dated December 9, 2011, CIG responded to the NOA by submitting its amended procedures. Based on our review of the documentation, it had been determined that CIG had adequately addressed items #1, #3 and #4, but did not address the deficiency cited in item #2. On March 19, 2012, PHMSA issued CIG a letter of Inadequate Response concerning this matter. On March 28, 2012, PHMSA received CIG’s Supplemental Response to the NOA that provided amended welding manual procedures addressing item #2 and finalized Ruby Pipeline’s O&M Manual procedures. Upon review of the newly-amended procedures, it appears that all inadequacies outlined in the NOA have been corrected. Accordingly, this case, CPF 5-2011-1008M, is now closed and no further action is contemplated with respect to the matters involved in this case. Thank you for your cooperation in this matter. Sincerely, Chris Hoidal Director, Western Region Pipeline and Hazardous Materials Safety Administration cc: PHP–60 Compliance Registry PHP-500 C. Lee (#135653)#
