As Chevron Gets Ready to Appeal State Order, Kern County Spill Continues to Grow. One of the largest oil spills our state has seen in decades is still growing. The oil giant Chevron told regulators almost a million gallons of fluid has burst through the ground near the site of one its oil wells about 30 miles from Bakersfield. Chevron also told state officials it plans to appeal an order from regulators calling for it to “take all measures” to stop the spill and ensure it doesn’t happen again.
