Dear Mr. Keyser:
On December 14, 2007, Columbia Gulf Transmission (Columbia Gulf) experienced a failure of
its 30-inch natural gas pipeline near Delhi, LA. As a result of the incident the Pipeline and
Hazardous Materials Administration (PHMSA) issued a Corrective Action Order (CAO), 4-
2007-1017H, dated December 19, 2007, requiring Columbia Gulf to take corrective actions with
respect to its natural gas pipeline system.
The cause of the failure was determined to be external corrosion and Columbia Gulf presented a
plan of corrective measures designed to prevent additional in-service failures. Through field and
records inspections over the past three years, PHMSA has determined that Columbia Gulf has
substantially completed the requirements of the CAO. Consequently, PHMSA has closed the
CAO, CPF 4-2007-1017H.
Sincerely,
R. M. Seeley
Director, Southwest Region
Pipeline and Hazardous
Materials Safety Administration
