NTSB opens public docket for Danville, Kentucky pipeline rupture investigation

The docket for this investigation includes more than 3600 pages of factual information, including reports on pipeline operations, integrity management, metallurgical testing, and emergency response efforts. The docket also includes interview transcripts, photographs, employee training records, and other investigative materials.

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 Enbridge Inc., ruptured and released natural gas that ignited. One person was fatally injured in the accident that destroyed five residences, damaged 14 other residences, and burned about 30 acres of land, including railroad tracks.

The public docket for this investigation is available online here.
