The incident happened around 5pm Friday. Bruce Clawson with the Texas City Office of Emergency Management said it was a small flange, where two pipes connect, that is on fire.
Clawson said there was a small leak at the plant, but not a danger to the community.
A BP spokesperson says a compressor tripped on a unit during heavy storms there with lightning. As a result of the compressor trip, BP says unit operations initiated a shut down of the unit and a fire broke out.
There were no injuries associated with the incident. BP dispatched a contract company with mobile environmental monitors into the community; those monitors have registered no abnormal readings.
There is no estimate on when the hydrocracker will restart.
BP says the BP Fire Department is on the scene to prevent re-ignition.
