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.\n\nPHMSA trend classification: significant incident, not serious.\n\nPHMSA standardized cause: INCORRECT OPERATION — OTHER INCORRECT OPERATION.\n\nPHMSA indexed costs: $192,163 reported total cost, $103,534.163 in 1984 dollars, $207,543.834 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data.
