The docket contains only factual information collected by NTSB investigators; it does not provide the final report, nor does it contain analysis, findings, recommendations, or probable cause determinations. As such, no conclusions about how or why the rupture occurred should be drawn from the information within the docket. Analysis, findings, recommendations, and probable cause determinations related to the rupture will be issued by the NTSB in a final report at a later date.

A 30 in. pipeline owned and operated by Kinder Morgan, Inc., ruptured and released natural gas that ignited. The rupture resulted in an explosion, fire, and ejection of a 46 ft section of the pipeline. One residence was destroyed by the explosion and subsequent fire, resulting in two fatalities and one injury.

The public docket for this investigation is available online.
