Fire crews worked to clean up a pipe leaking hydrocarbon after it caught fire at the Chevron Refinery in Richmond Wednesday morning. Chevron officials called the Richmond Fire Department at 2:10 a.m. as a precautionary measure. Crews arrived to find a broken processing line with a hydrocarbon liquid leaking which reportedly ignited the flames. Crews were able to put out the small blaze shortly after 3 a.m. The leak was stopped at 5:30 a.m. and the clean-up process is continuing. No injuries were reported and all employees and contractors were safely accounted for, according to a Chevron refinery spokesperson. A Level One notification was made to Contra Costa County Health Services as precautionary protocol, but there is no danger to the community, according to Chevron officials. Crews remain on site to help clean up the liquid that spilled on the ground of the plant’s Fluid Catalytic Unit at Gate 31. An investigation is underway to determine the oil leak and fire.
