Narrative
On may 29, 2018 at approximately 18:04 a third party contractor installing edge drain made contact with a 1" high pressure natural gas service line pulling the service tee off an 8" steel (high pressure) pipeline causing gas to be released. The pipeline is located on five mile road, northville, michigan (wayne county). The contractor recognized contact had been made with the pipeline, exited the equipment and immediately notified consumers energy of the damage. No ignition, injuries or fatalities occurred as a result of the damage. Consumers personnel arrived onsite at approximately 18:37 and began monitoring surrounding locations to ensure gas was not migrating. A portion of the road was closed and the damaged location and surrounding buildings were continuously monitored until the pipeline was isolated and the gas was shut-off. On may 30, 2018 at approximately 13:25 the damaged section of pipeline was isolated by utilizing a mueller control fitting west of the damage and closing the valve to the east of the damage location. Approximately 3' of 8" pipe was cut-out and replaced, a new service tee was installed and approximately 11' of service line replace to repair the damage and resume normal operations.
