Port Arthur firefighters are still investigating what caused a conveyer belt fire near a cargo ship.
The conveyor belt being used to load German wood pellets onto a ship caught fire according to the PIO.
Port Arthur firefighters arrived to the scene at 3 p.m.
City of Beaumont firefighters also helped put out the flames at the port to assist according to Captain Jimmy Blanchard of the Beaumont Fire Department.
A witness said he thought it was a fire coming from a refinery at first.
"I saw the black smoke and everything, I knew the refineries are around, and they had been burning the marsh," said Jeff Paton. "I thought, well that ain't a marsh burning so I wanted to check it out and I saw the smoke come on this side of the bridge."
The ship crew will have a supervisor on fire watch tonight to make sure the conveyer belt does not flare up again.
