RICHMOND, Calif. (KGO) -- Chevron is now saying the material that leaked from one of its pipelines into San Francisco Bay Tuesday was some combination of water and petroleum material, perhaps gasoline or diesel fuel. However, it's awaiting lab results.
Initial estimates had the spill at about 600 gallons, but a Chevron spokesperson said that is likely to change.
So far, according to Contra Costa County Public Health and the California Department of Fish and Wildlife, there have been no reports of health or environmental impacts.
'We don't know exactly what it is yet," said Linsi Crain, Manager of Corporate Affairs for the Richmond Refinery. "That is a pipeline that takes water products like gasoline and diesel and also oil to and from ships, so we are putting that through a lab."
