A HollyFrontier Corporation refinery in Tulsa, Oklahoma is operating normally after a blaze broke out Sunday morning.
No injuries have been reported and HollyFrontier told Reuters that production at the 125,000 barrel per day refinery has not been affected.
“The Refinery emergency response team was immediately mobilized and the fire was extinguished with no injuries or impact to plant operations,”a company spokeswoman told the news wire.
The fire started around 9 a.m. EDT but the company has not identified the unit where the blaze started.
The refinery’s emergency response team was able to quickly extinguish the fire, Oklahoma’s Newson6 said.
The major refinery units did not appear to be affected by the blaze, Reuters added.
Dallas-based HollyFrontier is currently investigating the cause of the incident.
According to HollyFrontier, the Tulsa Refinery primarily processes sweet crude oils, but can also process sour crude oils when economics dictate.
The refinery serves the markets in the Mid-Continent region of the United States.
