There's been a second fire at Port Panama City, related to Green Circle Bio-Energy's manufactured wood chips.

The fire started around 3:00 Monday morning in a barge full of the wood pellets. Authorities say the temperature in the barge reached about 140-degrees, which caused the pellets to spontaneously combust.

Port officials say it's the first time in four years they had a spontaneous combustion fire.

Workers use a sixty foot crane to remove the lid from the barge so firefighters could fight the fire.

Green Circle has been storing the pellets in barges since May, when short in a conveyor belt sparked a huge fire.

Wayne Stubbs is Port Panama City Executive Director. "Well you know now we are working to address there are only three more barges, that are still loaded with wood pellets. We actually are at the last stages of repairing our warehouse and we are believing that we will not need to use these barges, or the shipping company will not need to use these barges more than a few more weeks."

That fire back in May destroyed the conveyor belt and heavily damaged the port’s warehouse. Total damages were about 2-million dollars. The port hopes to have the warehouse repaired ready for use in about 2-more weeks.
