ATLANTA – A pipeline that burst, leaking nearly 255,000 gallons of gasoline in Alabama, triggered fuel shortages at southern gasoline stations and sent pump prices soaring over the weekend, the Associated Press reports. Colonial Pipeline had one of its two main lines rupture, but the company said it was sending “significant volumes” over the remaining pipeline to compensate for the disruption of service.

Despite those efforts, consumers have found “out of service” bags on pumps in the Carolinas, Tennessee, Georgia and Alabama. The cause of the leak has yet to be identified, but the Pipeline and Hazardous Materials Safety Administration (part of the U.S. Department of Transportation) was investigating the matter.

Pump prices have risen in states impacted by the shortage, including Alabama (up 20 cents), Georgia (up 5 cents), North Carolina (up 11 cents), South Carolina (up 13 cents) and Tennessee (up 6 cents). Colonial Pipeline is building a temporary work-around line to ship fuel until the situation is resolve.

Colonial Pipeline is critical to the eastern supply of fuel; the company announced the bypass line has been completed and services will resume next Wednesday, according to John Eichberger of the Fuels Institute.

“The U.S. fuel supply and distribution system is extremely efficient and effective, but when there is a disruption to a major artery of that system, the effects can be significant,” Eichberger said. “Luckily, the effects of this pipeline situation will be temporary as operations are being restored. The shortages experienced so far are to be expected when supplies are disrupted, but the market is working to quickly stabilize the situation and return conditions to normal.”
