HOUSTON (ICIS)--A malfunction over the weekend at Marathon Oil’s Texas City refinery in Texas led to emissions of hydrofluoric acid and hydrocarbons, the company said on Monday.

There was no off-site impact, said Shane Pochard, spokesman for Marathon.

“The source of the small release at Marathon’s Texas City refinery has been located and our crews have isolated it,” Pochard said.

Marathon did not comment on the operational status of the refinery or the source of the release.

A shelter-in-place warning was initially issued on Sunday afternoon by the Texas City emergency management office, but the warning was lifted shortly thereafter when air monitoring did not detect hydrofluoric acid in the air, according to news reports.

The malfunction led to the release of isobutene, butane, propane and hydrofluoric acid released from the depropanizer tower due to unknown causes, according to a filing with the US National Response Center.

No injuries were reported.

Marathon’s Texas City refinery has 76,000 bbl/day of capacity, according to the US Energy Information Administration (EIA).
