Department\nof Transportation\nPipeline and Hazardous Materials\nSafety Administration\nMr. David Chittick\nDirector, Pipeline Engineering\nTransCanada Pipelines Limited\n450 - 1st Street, S.W.\nCalgary, Alberta, Canada T2P 5Hl\n1200 New Jersey Ave., SE\nWashington, DC 20590\n'JUl16201O\nDocket No. PHMSA-2009-0055\nDear Mr. Chittick:\nOn February 6,2009, TransCanada Pipelines Limited, operator of the American Natural Resources\nPipeline (TCPL-ANR) wrote to the Pipeline and Hazardous Materials Safety Administration\n(PHMSA) requesting a special permit to waive compliance from PHMSA's pipeline safety\nregulation in 49 CFR § 192.611 for four (4) segments of the TCPL-ANR natural gas transmission\npipeline system located in St. Martin Parish, Louisiana. The regulation requires confirmation or\nrevision of the maximum allowable operating pressure (MAOP) for a pipeline segment where the\nclass location has changed. If granted, the special permit would have allowed TCPL-ANR to\ncontinue to operate four (4) segments of the 20-inch Line 716 pipeline located in St. Martin Parish,\nLouisiana at their current MAOP of 1,050 pounds per square inch gauge (psig).\nPHMSA is denying the special permit request due to Line 716 pipeline gas quality issues from gas\nsupplies, the 1983 internal leak due to internal corrosion and the presence of pre-1970 EFW pipe in\nthe Class 3 location special permit segments. The reasons for this denial are more fully described in\nthe special permit analysis and findings document enclosed with this letter. This document and all\nother pertinent documents are available for review in Docket No. PHMSA-2009-0055 in the Federal\nDocket Management System (FDMS) located on the internet at www.Regulations.gov. PHMSA is\ngranting TCPL-ANR until September 30,2011, to complete pipe replacements to comply with the\nrequirements of § 192.611.\nMy staff would be pleased to discuss this denial or any other regulatory matter with you.\nJohn Gale, Director of Regulations (202-366-4046), may be contacted on regulatory matters and\nAlan Mayberry, Deputy Associate Administrator for Pipeline Safety (202-366-5124), may be\ncontacted on technical matters specific to this special permit request.\n~~\nJeffrey D.
