Location
CO, ADAMS
Narrative
Incident is still under investigation. Delay in notice due to original belief that gas source was biogenic and not natural gas. March 19, 2008 supplemental report: after site investigation and laboratory investigation, depth of cover, leak description, and apparent cause were completed. There was extensive tree root growth around the 2" steel main. A tree root directly under the threaded coupling appears to have caused bending stresses and the gas leak.
