About ten barrels of gasoline and diesel fuel were spilled ort the two leaks, requiring soil removal. There were no injuries or evacuations.
About 14, gallons of fuel were leaked, with about 5, of it recovered. Investigators found that the pipe, which was installed inhad leaked due to internal corrosion. The failure caused crude oil price to spike throughout the World. About people were evacuated from a neighboring elementary school, a supermarket, and 30 to 40 houses in approximately a 4-mile 6.
