Narrative
Note, this report is the same as the 6/15/2012 report. We are resubmitting to close and finalize the report an explosion and subsequent fire occurred on may 13th 2012 at 23:53 at 36 s. Utah street, newark ohio, 43055. Michael clark of the residence had just entered his garage at the time of the explosion. The source of ignition has not been determined, however it has been speculated that he was entering the garage to smoke a cigarette. Two other residents were home at the time of the explosion and fire, dakneeka palmer, the fiance of michael clark, and their 9-month-old daughter, legacee. Both escaped the house unharmed. The energy coop was contacted by the licking county 911 dispatcher at 01:34 (5/14/12 - 1 hour 41 minutes after the explosion) to respond to the site to ensure gas was off to the structure. Two energy coop employees were dispatches, a leakage inspector michael carr and a service tech tom cooper. Tom arrived 02:05 and mike arrived at 02:20. They verified gas was off and began a leakage investigation. At 3:05, a leak was found under the 20' wide approach apron of the driveway at 36 s. Utah. The leakage extents were identified and the decision to shut the main down along with 8 customers was made. The valve to shut the line down was turned at 05:26 hours. The 2" main line servicing the area was excavated and cut on the north end and south end outside of the leakage area. Approximately 250' of 2" plastic main line was installed on the opposite side of utah avenue. The new line was tie back into the existing line in a manner that isolated the gas main in the leakage area. The old line was capped to preserve the line for further testing. Gas service was reestablished to the neighborhood. Odorant readings were taken and found to be well within required limits. The remainder of the neighborhood was surveyed for leakage to ensure the area was safe as it related to gas service. At 09:00 on may 16th , 2012 we returned to the site to perform an investigation. We pressure tested the isolated main line at normal operating pressure (43#) to test for leakage. We found leakage on the isolated 191' of 2" bare steel. We isolated approximately 90' north of the 36 s. Utah driveway and pressure tested it. We found no leakage. We tested the southern section (approximately 100') and found leakage. We excavated to expose the main line just south of the driveway to 36 s. Utah and cut the main to isolate aproximately 45' that was under the drive way. We pressure tested the 65'section south of the driveway and found no leakage. We pressure tested the service line on the south side of the structure and found no leakage. This isolated the leakage to the 45' section located under the driveway. We cut the concrete and put pressure on the piping and determined there were 2 leakage areas approximately 12' appart under the existing 20' concrete driveway.
