The CAO required TransCanada Northern Border, Inc., to take immediate corrective actions with respect to its gas transmission pipeline known as the Bison Pipeline which experienced a failure on July 20, 2011. After review of the records and the work performed on these pipeline systems, the Director of the Western Region, PHMSA, has determined that TransCanada Northern Border, Inc. has satisfactorily complied with the terms of that CAO. Accordingly, this case is now closed. Thank you for your assistance in bringing this effort to an acceptable conclusion. Sincerely, Chris Hoidal Director, Western Region Pipeline and Hazardous Materials Safety Administration cc: PHP-60 Compliance Registry PHP-500 Allen/Larson PHP-300 Barrett#
