AMERENIP

Incident Narrative

AMERENIP RECEIVED A CALL FROM AN OCCUPANT AT AN OFFICE BUILDING AT 718 ELLIOTT IN KEWANEE REPORTING A GAS IGNITION ASSOCIATED WITH A FURNACE. AMERENIP QUALIFIED EMPLOYEES RESPONDED TO THE CALL AND UPON ARRIVAL FOUND THAT THE BUILDING WAS BEING VENTILATED BY THE KEWANEE FIRE DEPARTMENT. THE AMERENIP GAS FACILITIES WERE INITIALLY INSPECTED AND DISCOVERED THAT A LEAKING DOWNSPOUT WAS DRIPPING ON THE GAS PRESSURE REGULATOR WHICH ICED OVER CAUSING A SUSPECTED HIGHER THAN NORMAL DELIVERY PRESSURE. UPON FURTHER INVESTIGATION THE DELIVERY PRESSURE WAS CHECKED AND FOUND TO BE 8.9 PSIG TO CUSTOMER APPLIANCES THAT NORMALLY RECEIVE 0.25 PSIG GAS PRESSURE. THIS HIGHER THAN NORMAL PRESSURE APPARENTLY CAUSED AN IMPROPER OPERATION OF THE A FURNACE AND A SUBSEQUENT GAS IGNITION. ESTIMATED PROPERTY DAMAGE IS $18,000 WHICH IS LESS THAN THE $50,000 THRESHOLD FOR A REPORTABLE INCIDENT; HOWEVER, UPON REPORTING THIS EVENT TO THE ILLINOIS COMMERCE COMMISSION, THE MANAGER OF PIPELINE SAFETY RECOMMENDED THAT THIS BE REPORTED AS AN EVENT THAT IS SIGNIFICANT, IN THE JUDGMENT OF THE OPERATOR, EVEN THOUGH IT DID NOT MEET THE CRITERIA OF PARAGRAPH (1) OR (2) IN CFR 49 191.3.
