Incident Narrative
ON SEPTEMBER 30, 2020 OUR UPSTREAM SUPPLIER'S CONTRACTOR INSTALLED A TEMPORARY ALTERNATE FEED TIED DIRECTLY INTO THE REGULATOR SETTING AND REMOVED A SECTION OF SUPPLY PIPING PROVIDING THE PRIMARY FEED TO THE KITTS HILL REGULATOR STATION. THIS WORK WAS DIRECTLY OBSERVED BY COLUMBIA'S MEASUREMENT AND REGULATION EMPLOYEES ON-SITE. WHEN THE PRIMARY FEED WAS TAKEN OUT OF SERVICE IT CAUSED A LOSS OF THE POWER GAS (I.E. SUPPLY GAS) SUPPLY TO THE INSTRUMENT LOADED REGULATORS. THE LOSS OF POWER GAS SUPPLY TO THE REGULATORS RESULTED IN THE REGULATORS FAILING OPEN AND ALLOWING THE UNRESTRICTED FLOW OF GAS INTO THE DOWNSTREAM SYSTEM, PRODUCING AN OVER PRESSURIZATION OF THAT SYSTEM. THE SYSTEM WAS SHUT DOWN FOR SAFETY AND RESULTED IN NO MAJOR DAMAGE TO COLUMBIA'S OR CUSTOMERS' PROPERTY. THE SYSTEM WAS EVALUATED AND ASSESSED FOR SAFETY AND THE SYSTEM WAS PLACED BACK INTO OPERATION.
