CERTIFIED MAIL - RETURN RECEIPT REQUESTED
December 28, 2010
Mr. Michael L. McCann
Vice President, Pipeline & Terminals
Tesoro Refining and Marketing Company

San Antonio, TX 78259
CPF 3-2005-5009
Dear Mr. McCann:
On September 19-20, 2002; September 30-October 3, 2002; October 29-October 30, 2002 and
November 19-21, 2002, representatives of the Central Region, Office of Pipeline Safety, and
the Minnesota Office of Pipeline Safety, pursuant to Chapter 601 of 49 United States Code,
conducted an onsite pipeline safety inspection of your Operation and Maintenance Procedural
manuals at Roseville, MN and your records and field facilities in North Dakota and
Minnesota. As a result of the inspection, Tesoro was issued a Notice of Amendment on
February 10, 2005, which proposed amendment of your procedures.
Tesoro submitted its amended procedures on March 11, 2005. 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,
David Barrett
Director, Central Region
Pipeline and Hazardous Materials Safety Administration
