CERTIFIED 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
