CERTIFIED MAIL - RETURN RECEIPT REQUESTED

Closure Letter
Dear Mr. Rea:
On June 19 to 22, 2012, representatives from the Pipeline and Hazardous Materials Safety
Administration (PHMSA) and the Wyoming Public Service Commission, pursuant to chapter 601 of
49 United States Code, conducted an on-site pipeline safety inspection of Anadarko Petroleum
Corporation’s (Anadarko) procedures for their Control Room Management (CRM). The inspection
was conducted in Gillette, Wyoming. As a result of the inspection, Anadarko was issued a Notice of
Amendment on January 9, 2013, which proposed amendment of your procedures.
Anadarko submitted its amended procedures on January 11, 2013. My staff reviewed the amended
procedures, and it appears that the inadequacies outlined in this Notice of Amendment have been
corrected.
This letter is to inform you no further action is necessary and this case is now closed. Thank you for
your cooperation.
Sincerely,
Chris Hoidal
Director, Western Region
Pipeline and Hazardous Materials Safety Administration
