Narrative
At approximately 13:57 on december 13, 2018 atlanta gas light company (aglc) received telephonic notice from the savannah fire department indicating that damage had occurred to aglc natural gas facilities in the area of 100 general mcintosh blvd in savannah, ga. Shortly after arrival to the site, aglc crews determined damage had occurred to a 125 psig 8-inch steel main that crosses the savannah river supplying customers to hutchison island. The damaged was found to occur on the west land side of the river. To stop the flow of gas at the damage, a nearby valve was turned off which caused a total of seventeen customers to lose natural gas service for approximately 9 hours. The excavator responsible for the damage was drilling for pilings as part of a site development project in the area. There was no valid locate request at the time of excavation. The most recent locate request for the area of the damage by the excavator was received by aglc on august 23, 2018. As a normal locate request in georgia is valid for thirty (30) days, this request was valid until september 22, 2018. As the pipeline is still shut down pending repair or replacement, customers who lost natural gas service due to the damage, are being provided service by a compressed natural gas tanker that has been placed on the island. Pipeline that was damaged was replaced with a new 8-inch steel pipeline. Natural gas was restored to customers on the island on may 15, 2019. During the pipeline shutdown, customers were provided service by compressed natural gas facilities that were placed on the island. Additional nrc report number 1232992 was created for the same event after a 48-hour supplemental call was placed with the nrc.
