ATLANTA — Gas prices spiked and drivers found “out of service” bags covering pumps as the gas shortage in the South rolled into the work week, raising fears that the scattered disruptions could become more widespread.

The shortage is blamed on a pipeline rupture and leak of at least 252,000 gallons of gas in Alabama. The pipeline company has two main lines and said Monday that it is shipping “significant volumes” on the second of the two lines to limit the impact of the interruption on the other line.

Colonial Pipeline said supplies have either been delivered or are on their way to locations in Alabama, Georgia, Tennessee, South Carolina, and North Carolina.

Still, some motorists discovered bone-dry pumps.

Lindsey Paluka, 28, stopped at a Shell gas station in the East Atlanta neighborhood only to find a gas pump handle covered by a black garbage bag.

“I’m definitely on empty, so I’m going to have to figure something out,” she said.

Alpharetta, Georgia-based Colonial has acknowledged that between 252,000 gallons and 336,000 gallons of gasoline leaked from a pipeline near Helena, Alabama, since the spill was first detected Sept. 9. It’s unclear when the spill actually began.

According to a preliminary report, it wasn’t possible to immediately pinpoint the leak, partly because highly flammable benzene and gasoline vapors hung in the air and prevented firefighters, company officials and anyone else from being near the site for more than three days.

State workers discovered the leak when they noticed a strong gasoline odor and sheen on a man-made retention pond, along with dead vegetation nearby, the Pipeline and Hazardous Materials Safety Administration said in the report.
