Southern governors lift driver rules after gas spill

The governors of three Southern states are lifting restrictions on the number of hours that truck drivers delivering fuel can work, hoping to prevent shortages in both states after the shutdown of a pipeline that spilled at least 252,000 gallons of gasoline in rural Alabama.  Governors can suspend federal transportation regulations during emergencies.  Colonial Pipeline has said most of the leaked gasoline is contained in a retention pond near the city of Helena and there's no public safety concern. The spill was first detected on Sept. 9, but it's not clear when it began.  The company increased its estimate of the spill's size on Friday, saying it was between 252,000 and 336,000 gallons. Colonial doesn't expect to fully reopen the pipeline until next week. The pipeline runs from Texas to New Jersey, supplying fuel to states in the Southeast and on the East Coast.
