"The NTSB's work is an important step in the effort to enhance pipeline safety. Our own understanding of the events generally aligns with that of the NTSB.

As we've said since that tragic day, we take responsibility for what happened.

These include installing automatic shut-off devices, accelerating implementation of a Safety Management System, or SMS, enhancing emergency preparedness, enhanced mapping, and more.

"We cooperated fully with the NTSB to help assess what happened and we thank them for their diligent work.
