320105005M_Closure Letter_03112011_text.pdf, page 1Official PDFCERTIFIED MAIL - RETURN RECEIPT REQUESTED March 11, 2011 Mr. Brian Coffman President ConocoPhillips Pipe Line Company 600 N. Dairy Ashford Room TA 2010 Houston, Texas 74079 CPF 3-2010-5005M Dear Mr. Coffman: On February 25, 2010, the Pipeline and Hazardous Materials Safety Administration (PHMSA) received a Safety Related Condition Report (SRCR) from ConocoPhillips Pipe Line Company (ConocoPhillips). During PHMSA Central Region’s activities following receipt of the SRCR, pursuant to Chapter 601 of 49 United States Code, ConocoPhillips’ procedures were inspected for the sufficiency of pressure reductions to be taken upon discovery of immediate repair conditions, i.e., metal loss greater than 80% of nominal pipe wall thickness. ConocoPhillips was issued a Notice of Amendment (NOA) on March 30, 2010, which proposed amendment of your procedures. ConocoPhillips submitted its amended procedures on May 5, 2010. My staff reviewed the amended procedures, and it appears that the inadequacies outlined in this Notice of Amendment have been corrected. The review of the amended procedure was limited to the item listed in the NOA and future PHMSA inspections will review the entire ConocoPhillips’ CPPL-MPR-4104, “General Line and Equipment Maintenance – Derating a Pipeline to a Lower Operating Pressure,” procedure. This letter is to inform you no further action is necessary and this case is now closed. Thank you for your cooperation. Sincerely, David Barrett Director, Central Region Pipeline and Hazardous Materials Safety Administration#
