CVR Chief Executive Officer Jack Lipinski released a statement Sunday that said the company was “cooperating fully” with the investigation.

“Our focus is to determine how this accident occurred and what steps must be taken to avoid a repeat of this incident,” Lipinski said.

CVR purchased the refinery, which has a daily capacity of 70,000 barrels of crude and produces gasoline, diesel fuel, military jet fuel, solvents and asphalt.

Previous incidents at the refinery include a boiler explosion in 2010, a propane leak in 2008 and fire that was sparked by lightning in 2007.

There were no injuries in those incidents.
