## Document text

Gas transmission and gathering incident in PORT ALLEN, WEST BATON ROUGE County, LA. Reported cause: OTHER INCIDENT CAUSE. Reported consequences: 0 fatalities, 0 injuries, 331 NATURAL GAS released, $1,000,000 reported property damage. Operator-reported incident data submitted to PHMSA, generally within 30 days. Records may be supplemented or corrected and do not represent final agency causal findings.

Report number: 20140115.

Operator ID: 12696.

Reported incident date: 7/19/2014 9:30.

Location detail: 4371+87.24

Cause detail: UNKNOWN

Cause detail: DURING SURVEY WORK AT THE MISSISSIPPI RIVER CROSSING FOR FUTURE CONSTRUCTION, A SMALL AMOUNT OF GAS BUBBLES WERE NOTICED IN THE RIVER. OPERATIONS PERSONNEL ISOLATED THE PIPELINE AND VERIFIED THAT THE PIPELINE HAD A SMALL LEAK. ORIGINAL INVESTIGATION DID NOT MEET NRC REPORTABLE CRITERIA. PIPELINE REMAINED SHUTDOWN UNTIL A PLAN OF ACTION WAS DETERMINED. LATER, IT WAS DETERMINED THAT A TEMPORARY REPAIR USING A PIPELINE CLAMP WAS WARRANTED. THESE PIPELINE REPAIRS EXCEEDED THE MINIMUM REPORTING REQUIREMENTS AND THE NRC WAS SUBSEQUENTLY CALLED. UPON COMPLETION OF THE REPAIR, THE PIPELINE WAS LEAK TESTED AND RETURNED TO SERVICE. INCIDENT CAUSE IS UNKNOWN BECAUSE THE PIPELINE IS UNDER THE MISSISSIPPI RIVER AND DOES NOT CURRENTLY ACCOMMODATE INTERNAL INSPECTION TOOLS.

PHMSA trend classification: significant incident, not serious.

PHMSA standardized cause: ALL OTHER CAUSES — UNKNOWN.

PHMSA indexed costs: $1,000,327 reported total cost, $507,644.32 in 1984 dollars, $1,249,892.393 in current-year dollars.
