CLEMMONS, N.C. >> Drivers waited in long lines at gas stations in the Southeast today after a hack of the nation’s largest fuel pipeline led to distribution problems and panic-buying, draining supplies at thousands of gas stations.

There is no gasoline shortage, according to government officials and energy analysts. But there is a problem getting the fuel from refineries on the Gulf Coast to the states that need it, and officials are scrambling to find alternate routes to deliver that fuel.

If the pipeline shutdown extends past the weekend, it could create broader fuel disruptions.

The Colonial Pipeline, which delivers about 45% of the fuel consumed on the East Coast, was hit on Friday with a cyberattack by hackers who lock up computer systems and demand a ransom to release them. The attack raised concerns, once again, about the vulnerability of the nation’s critical infrastructure.

The pipeline runs from the Gulf Coast to the New York metropolitan region, but states in the Southeast are more reliant on the pipeline. Other parts of the country have more sources to tap. For example, a substantial amount of fuel is delivered to states in the Northeast by massive tankers.

“What you’re feeling is not a lack of supply or a supply issue. What we have is a transportation issue,” said Jeanette McGee, spokeswoman for the AAA auto club. “There is ample supply to fuel the United States for the summer, but what we’re having an issue with is getting it to those gas stations because the pipeline is down.”

Jamar Gatison, 36, was filling up his tank in Norfolk, Virginia, today before a doctor’s appointment.

“I’m about to run out of gas, so I have no choice,” the construction worker said while waiting in line at a 7-Eleven. “I’m also an Uber Eats driver. I also need gas for that,” Gatison said, adding that he probably won’t deliver food tonight because he doesn’t want to wait in line again while the shortage continues.

In North Carolina, 65% of gas stations were out of fuel, according to Gasbuddy.com, a technology firm that tracks real-time fuel prices across the country. Just outside Raleigh, two people were charged with assault after fighting and spitting in each other’s faces while arguing over their spots in line Tuesday at a Marathon gas station, authorities said.

North Carolina Democratic Gov. Roy Cooper urged people today to only buy gas if their tank is low, and to report any instances of price gouging.

“We will continue our efforts to help make sure there is an adequate supply of fuel,” Cooper wrote on Twitter.

Georgians were also getting squeezed, with 43% of stations there out of gas, according to Gasbuddy.com. In Virginia, 44% of stations were out, and in South Carolina, 16% had no fuel.

Along the Appalachian Trail, which stretches from Georgia to Maine through some of the most rugged and remote terrain in the southeast U.S., hikers depend on car and van shuttles to ferry them to and from the trail and get them back to civilization.

“If I don’t have the gas, I’m not running,” said Ron Brown of Ellijay, Georgia, who operates Ron’s Appalachian Trail Shuttles and often takes hikers on hourslong trips from Atlanta’s airport into the north Georgia mountains and to and from many points along the trail.

Mary Goldburg, 60, of Norfolk, Virginia, waited more than 20 minutes for a slow-operating pump at a 7-Eleven to fill up her tank today. Her job includes delivering t-shirts for events and other promotional products.

“I can’t get paid until my customers get their products,” Goldburg said. “And then I can bill them for it. And then I get paid after that.”

Government officials have said Colonial anticipates restarting most of its operations by the end of the week. However, the disruption is taking place at the time of year when Americans begin to become more mobile, especially as the nation emerges from the pandemic.

Four to five cars were lined up at each pump at a Circle K in Clemmons, North Carolina. Several people said they had driven to multiple gas stations to find one that had gas. Across the street, gas stations were out of fuel.

Mair Martinez, who works in landscaping, was filling up his lawn equipment and truck after checking several other gas stations without luck.

“I’m a local landscaper, so that’s why we’ve come in today, to fill up everything. We need to do something tomorrow, and everybody needs some gas right now,” he said.

Johnathan King, who works for an area towing company, was filling up his tow truck. He said he typically does 10 to 12 service calls a day, driving between several area cities.

“It’s going to be very hard for us. Hopefully we’ll be able to get through it,” he said.

Multiple U.S. agencies are coordinating to relax rules and enable fuel to be shipped faster using trucks, trains or ships, but those changes are having little impact so far.

The White House said today that the Department of Transportation is now allowing states served by the pipeline to use interstate highways to transport overweight loads of gasoline and other fuels. But there’s a national trucker shortage, so the industry isn’t able to put many more trucks on the road.

There are about 121,000 convenience stores which sell about 5,300 gallons per day of gasoline, accounting for about 80% of retail fuel sales. Most truck deliveries bring 8,000 gallons of fuel, but at many stores demand has been two to five times the normal amount, said Jeff Lenard of the National Association of Convenience Stores, in a conference call with reporters.

Rationing has been imposed after some natural disasters, including Hurricane Sandy in 2012, but there could be resistance to it this time, especially if it looks like the pipeline could return to normal operation in a few days.

It could also backfire. “Once rationing occurs, more panic buying ensues,” said Ryan McNutt, CEO of the Society of Independent Gasoline Marketers of America.

The national average price for a gallon of gasoline ticked above $3 for the first time since 2016 today, according to the AAA. Prices begin to rise around this time every year and the auto club said today that the average price hit $3.008 nationally.

“You go to some states, and you’re going to see much higher increases, especially in the South, because that’s where you’re seeing the largest impact in terms of strain of gasoline, or strain of people,” McGee said.
