UTC Pipeline Safety staff recommend $5.7 million fine in deadly Toppenish natural gas fire

A state investigation has uncovered 66 alleged safety violations by Cascade Natural Gas following a September 2023 liquefied natural gas (LNG) fire in Toppenish that killed one person and injured another.

According to a news release issued earlier this month by the Washington Utilities and Transportation Commission (UTC) Pipeline Safety staff, the commission recommended a $5,668,595 penalty against the Kennewick-based utility.

The incident occurred on Sept. 22, 2023, during an LNG transfer at a temporary fueling site.

According to the staff’s findings, a Southern Pines Trucking driver pulled away from the active transfer too early, resulting in the release of approximately 83 barrels of LNG.

The gas formed a vapor cloud that ignited after coming into contact with a nearby ignition source.

The fire led to fatal injuries for 62-year-old Earnest D. Barnett, a contractor on-site who died two days later despite receiving medical care. The other contractor escaped unharmed.

In addition to the fatality and injuries, the fire damaged equipment and vehicles, but did not result in further injuries or reported environmental harm.

The commission’s staff alleges that Cascade Natural Gas failed to follow multiple safety protocols, including properly securing equipment and adhering to emergency procedures.

Investigators say these violations contributed to the release and ignition of the LNG.

The commission will review the complaint and evidence before making a final decision on the recommended penalty.

Cascade Natural Gas did not respond to a request for comment.
