Cause detail: INCORRECT OPERATION

Cause detail: ON JUNE 30TH AT APPROXIMATELY 7:52PM GAS CONTROL RECEIVED AN ALARM OF AN OVERPRESSURE SITUATION ON THE TOPEKA 20" AT OTTAWA STATION. OPERATIONS PERSONNEL WERE CONTACTED AT 8:05PM AND ARRIVED TO OTTAWA STATION AT 8:09PM AND FOUND LINE PRESSURE ON THE TOPEKA SYSTEM HAD EXCEEDED IT'S MAOP OF 450 PSIG DUE TO A LIGHTENING STORM CAUSING THE WORKING REGULATOR 1137 R TO FAIL OPEN. THE MONITOR REGULATOR 1137 RM FAILED TO OPERATE EXPOSING LINE ES TO A PRESSURE OF 679 PSIG. IT WAS LATER DETERMINED THE MONITOR REGULATOR FAILURE WAS DUE TO PNEUMATIC CONTROLLER'S SUPPLY VALVE BEING SHUT. AT 8:15 THE TOPEKA 20" RUPTURED APPROXIMATELY 3 MILES SOUTH OF LAWRENCE KANSAS. RICHARD HANES ARRIVED ON SITE OF RUPTURE AT 9:09PM, AND REPORTED THAT GAS WAS BLOWING AT MAINLINE PRESSURE AND THERE WAS NO FIRE. AT 9:42PM THE BALDWIN MAIN LINE GATE WAS CLOSED, SHUTTING IN THE RUPTURED SECTION. A CHECK VALVE AT HASKELL BOTTOMS NEAR LAWRENCE PREVENTED LOSS OF PRESSURE ELSEWHERE ON OUR SYSTEM.
