BEFORE THE WORK WAS BEGUN THE NORTHERN ILLINOIS GAS COMPANY MARKED THE LOCATION OF ITS SERVICE LINES AND MAINS. ON THE MORNING OF MARCH 13, 1986, WHILE EXCAVATING EAST OF THE MARKED SERVICE LINE FOR 204 14TH STREET, THE CONTRACTOR'S CREW SNAGGED A GAS SERVICE LINE WITH A BACKHOE. BECAUSE THIS GAS SERVICE LINE WAS APPROXIMATELY 4 FEET AWAY FROM THE MARK AND BECAUSE OF THE LINE'S DETERIORATED CONDITION, THE CONTRACTOR'S CREW ASSUMED CORRECTLY THAT IT WAS ABANDONED AND USED IT AS AN INDICATION THAT THEY WERE NEAR THE AREA OF THE THE ACTIVE SERVICE LINE. THE FOREMAN INSTRUCTED THE BACKHOE OPERATOR TO TAKE OFF THE "FROST" USING THE BACKHOE, IN PREPARATION FOR EXCAVATING BY HAND DIGGING. SHORTLY THEREAFTER, ABOUT 7:30 A.M., THE BACKHOE SNAGGED THE ACTIVE, WRAPPED, 3/4-INCH STEEL NATURAL GAS SERVICE LINE FOR 204 14TH STREET. THE LINE WAS OPERATING AT 28 PSIG AND WAS 30 INCHES BELOW THE SURFACE. ACCORDING TO THE FOREMAN, THE CREW COULD SMELL GAS BUT THEY DID NOT OBSERVE ANY BLOWING GAS AROUND THE SNAGGED SERVICE LINE. THE FOREMAN RADIOED HIS OFFICE AND REPORTED THE LEAK. AT 7:37 A.M. THE OFFICE PERSONNEL CALLED THE NORTHERN ILLINOIS GAS COMPANY (GAS COMPANY) AND INFORMED THE GAS COMPANY OF THE ACCIDENT BUT RECEIVED NO INSTRUCTIONS FROM IT. THE GAS COMPANY'S CALL RECORD SHOWED THAT THERE WAS A LINE HIT REPORTED AT ROUTE 30 (14TH STREET) AND GARDEN. THE RECORD HAD THE FOLLOWING HANDWRITTEN NOTE, "HIT LINE-DON'T KNOW IF BLOWING"; HOWEVER, THE RECORD WAS STAMPED "LEAK."
