As a result of the incident, the Pipeline and Hazardous Materials Safety Administration (PHMSA) issued a Corrective Action Order (CAO), 4-2003-1001H, dated February 26, 2003, requiring Enable to take corrective actions with respect to its pipeline system. The cause of the failure was determined to be selective seam corrosion on the pipeline and Enable presented a 10 year plan of identification and corrective measures designed to prevent additional in-service failures. PHMSA monitored the actions taken within the integrity verification process and reviewed records at Enable’s headquarters. PHMSA has determined that Enable has substantially completed the requirements of the CAO. Consequently, PHMSA has closed the CAO, CPF 4-2003-1001H. Sincerely, R. M. Seeley Director, Southwest Region Pipeline and Hazardous Materials Safety Administration#
