CERTIFIED MAIL - RETURN RECEIPT REQUESTED
March 17, 2011
Ms. Marie Sotak
Manager, Pipeline Safety
Williams Gas Pipelines
2800 Post Oak Boulevard
Houston, TX 77056
CPF 5-2009-1002M
Dear Ms. Sotak:
From June through August 2008, representatives from the Pipeline and Hazardous Materials
Safety Administration (PHMSA), pursuant to chapter 601 of 49 United States Code inspected
Williams Gas Pipeline’s (WGP) procedures, records and pipeline facilities in the states of
Georgia, Idaho, New Jersey, Texas, Utah, and Washington. As a result of the inspection,
Williams Gas Pipeline was issued a Notice of Amendment on April 15, 2009, which proposed
amendment of your procedures.
Williams Gas Pipeline submitted its amended procedures on September 18, 2009. 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
