CERTIFIED MAIL - RETURN RECEIPT REQUESTED
January 21, 2011
Mr. Royce Ramsay
Vice President, Operations
Northern Natural Gas Company
1111 South 103rd Street
Omaha, Nebraska 68124-1000
CPF 3-2009-1005M
Dear Mr. Ramsey:
On July 5-9, 2006, and June 19-21, 2006, representatives from the Pipeline and Hazardous
Materials Safety Administration (PHMSA), the Minnesota Office of Pipeline Safety, and
the Michigan Public Service Commission, pursuant to chapter 601 of 49 United States
Code, conducted an on-site pipeline safety inspection of the Northern Natural Gas
Company (NNG) integrity management procedures in Omaha, Nebraska. As a result of
the inspection, NNG was issued a Notice of Amendment on April 22, 2009, which
proposed amendment of your procedures.
NNG responded on May 22, 2009, with a description of the revisions made to its
procedures as a result of the inspection and then submitted its procedures on December 31,
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 that this case is now closed.
Thank you for your cooperation.
Sincerely,
David Barrett
Director, Central Region
Pipeline and Hazardous Materials Safety Administration
