Reported consequences: 0 fatalities, 0 injuries, 4154 NATURAL GAS released, $0 reported property damage. Operator-reported incident data submitted to PHMSA, generally within 30 days.

Location detail: 506-2 BD Cause detail: COMPRESSOR OR COMPRESSOR-RELATED EQUIPMENT Cause detail: AN INVESTIGATION INTO THIS INCIDENT IDENTIFIED EVIDENCE OF MOISTURE IN AN ELECTRICAL CONDUIT THAT TRIGGERED AN ELECTRICAL SHORT WHICH IN TURN ACTIVATED THE 4 INCH ESD VALVE. ACTIVATION OF THE VALVE RESULTED IN AN UNINTENDED RELEASE OF GAS. AS A FOLLOW-UP ACTION TO THIS INCIDENT, THE DESIGN TEAM CHANGED THE LOCATION OF THE ELECTRICAL CONDUIT SO THAT A RE-OCCURENCE TO A SIMILAR CONDITION IS ELIMINATED. HENCE; NO MOISTURE WILL ENTER INSIDE THE ELECTRICAL CONDUIT LEADING TO SIMILAR COMPONENTS THAT INITIATED THIS INCIDENT. ASIDE: PLEASE NOTE THAT THE INITIAL INCIDENT REPORT FOR CORINTH CS WAS READY FOR SUBMISSION ON APRIL 26, 2013. THE ODES SYSTEM EXPERIENCED AN ISSUE THAT REMOVED ALL PREVIOUSLY SUBMITTED INCIDENT REPORTS (FROM THE THREE OPIDS THAT COLUMBIA HAS) WITH MY DRAFT CORINTH CS INCIDENT REPORT FROM COLUMBIA'S OPID. AS OF TODAY, THE ODES SYSTEM IS RUNNING NORMALLY AND ALL PREVIOUSLY SUBMITTED INCIDENTS WERE RESTORED TO ALL THREE OPIDS. PLEASE REFER TO THE ATTACHED FILE FOR MORE INFORMATION. THANK YOU.
