CERTIFIED MAIL - RETURN RECEIPT REQUESTED
April 27, 2011
Mr. David Wallen
Vice President
MoGas Pipeline LLC
110 Algana Ct.
St. Peters, Missouri 63376
Re: CPF 3-2009-1013M
Dear Mr. Wallen:
On March 19-21, 2007, representatives of the Pipeline and Hazardous Materials Safety
Administration (PHMSA) and the Missouri Public Service Commission, pursuant to chapter
601 of 49 United States Code, conducted an on-site pipeline safety inspection of the MoGas
Pipeline (previously Missouri Pipeline Company) integrity management procedures in St.
Peters, Missouri. As a result of the inspection, MoGas was issued a Notice of Amendment on
July 28, 2009, which proposed amendment of your procedures.
MoGas responded on August 28, 2009, and has subsequently submitted its revised procedures.
My staff reviewed the amended procedures, including the latest revision submitted on April
26, 2011, 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 that this case is now closed.
Thank you for your cooperation.
Sincerely,
David Barrett
Director, Central Region
Pipeline and Hazardous Materials Safety Administration
