Docket No. PHMSA-2009-0061
Dear Mr. Chittick:
On February 6, 2009, TransCanada Pipeline Limited-American Natural Resources (TCPL-ANR)
wrote to the Pipeline and Hazardous Materials Safety Administration (PHMSA) requesting a
special permit to waive compliance from PHMSA's pipeline safety regulation in
49 CFR § 192.611, for one (1) segment of the TCPL-ANR natural gas transmission pipeline
system located in Lucas County, Ohio. The regulation requires confirmation or revision of the
maximum allowable operating pressure (MAOP) of a pipeline segment where the class location
has changed.
PHMSA is denying this special permit request, which would have allowed TCPL-ANR to
continue to operate a segment of the 20-inch Line 515 pipeline in Lucas County, Ohio at its
current MAOP of 858 pounds per square inch gauge (psig). The reason for this denial can be
found in the Special Permit Analysis and Findings document enclosed with this letter. This
document and all other pertinent documents are available for review in Docket No. PHMSA-
2009-0061 in the Federal Docket Management System (FDMS) located on the internet at
www.Regulations.gov.
PHMSA will grant TCPL-ANR until September 30, 2011, to complete pipe replacements
required to comply with the requirements of 49 CFR § 192.611.
My staff would be pleased to discuss this special permit or any other regulatory matter with you.
John Gale, Director of Regulations (202-366-4046), may be contacted on regulatory matters and
Jeff Gilliam, Director of Engineering (303-888-2587), may be contacted on technical matters
specific to this special permit.
Sincerely,

Associate Administrator for Pipeline Safety
