Incident Narrative
"AT 09:25 PIPELINE CONTROL CENTER (HCC) RESPONDED TO A TRANSMITTER FAILURE AT MP 599.83 WITH NO UPSTREAM OR DOWNSTREAM PRESSURE DEVIATIONS. HCC DISPATCHED PERSONNEL TO THE SITE FOR FURTHER INVESTIGATION. AT 13:10 A TECHNICIAN NOTIFIED HCC OF A SMALL FIRE ON A TRANSMITTER AND ASSOCIATED STAINLESS STEEL TUBING. THE TECHNICIAN WAS ABLE TO CLOSE A MANUAL INSTRUMENTATION VALVE TO ISOLATE THE TRANSMITTER AND EXTINGUISH THE FIRE. AN INVESTIGATION DETERMINED THAT SEVERE THUNDERSTORMS PASSED THROUGH THE AREA AT MP 599.83 MAINLINE VALVE SITE. WEATHER SERVICE DATA INDICATES SEVERAL LIGHTNING STRIKES IN CLOSE PROXIMITY TO THE PIPELINE AND VALVE SITE. IT WAS DETERMINED THAT AS THE LIGHTNING DISSIPATED THE ELECTRICAL CURRENT INTO THE GROUND, THE CURRENT SURGE WAS INDUCED ONTO THE DIXIE MAINLINE, TRAVELING TOWARD THE VALVE SITE AND COMPROMISED THE INTEGRITY OF THE SWAGELOK DIELECTRIC TUBING FITTINGS. THE SWAGELOK DIELECTRIC TUBING FITTINGS WILL BE REPLACED WITH A 2 INCH FLANGE AND PIKOTEK INSULATING KIT. A GROUNDING DAIRYLAND DECOUPLER WILL ALSO BE INSTALLED TO ISOLATE STRAY CURRENT FROM DOWNSTREAM COMPONENTS. 48 HOUR NRC UPDATE #1272771 WAS PLACED ON MARCH 5, 2020 AT 11:05."
