BENICIA, Calif. (KRON) — After 24 hours of battling the the Benicia port fire, officials say it is now extinguished.

Three small pockets of fire were left early Sunday morning after Saturday’s fire, city officials said in a tweet. The fire started around 12:20 p.m. on Saturday. The fire was put out around 12:24 p.m. Sunday afternoon.

The initial fire started at the base of silos surrounding vegetation. This part of the fire was put out quickly, officials said. However, the fire on the pier’s underside progressed into a four alarm fire.

KRON4 spoke with Deputy City Manager Mario Giuliani about the fire updates. He says great progress was made on reducing the fire.

“The damage is certainly concerning,” Giuliani said. “This is a port of Benicia that facilitates operations for Amports and the Benicia Valero Refinery. So both of those will be impacted to the extent that remains seen.”

Saturday, multiple fire crews responded to four-alarm structure fire near the port of Benicia. Firefighters have been at the scene since then.

The Dutra Group arrived with a crane to assist with lifting asphalt on the pier. Officials say this allowed access to the timber fires under the asphalt.

The fire produced heavy smoke that impacted nearby outdoor areas on Saturday. Officials are advising those with respiratory issues to limit outdoor exposure.

The city will continue to work with Valero Benicia Refinery and Amports to assist with port operations. A full damage assessment is expected to occur on Monday to allow all parties to access conditions and possible impacts to operations.

“As it relates to public health and safety, there is very little smoke,” the City Manager said. “The only thing visible now looks like steam. We had monitors on sight throughout the day taking measurements for air particles and nothing registered.”

The city plans to deploy 3,000 feet of barriers to capture loose debris from the incident. Boaters should remain a distance from the area, officials say.

The cause of the fire remains unknown and will be investigated. Officials say no injuries occurred from the fire.
