The lines from Houston to Louisiana - to which half of the refineries served by Colonial are attached - remained down on Thursday.
Colonial Pipeline Co, the biggest US fuels system operator, on Sunday said it would address storm-related gasoline shortages by seeking federal approval to move nonsummer grade gasoline from Texas to the Northeast.
In Colorado, the average gas price early Thursday was $2.42, up about 8 cents in the past week, according to travel group AAA's daily survey. The Colonial Pipeline runs from the Houston area to the NY harbor and includes more than 5,500 miles of pipeline, most of it underground.
The effect will continue for several weeks, if not months, after Harvey hammered the Gulf Coast for several days, causing floods that buried Houston and the surrounding area in several feet of water.
"We are going to have outages from Texas to Boston", said one East Coast market source. In many cases, the refineries were shut down as a proactive measure because the forecast called for flooding.
On Wednesday Valero told its East Coast customers that it would stop supplying customers that don't carry its logo at all northeast terminals from Pennsylvania up to ME, according to a customer who asked not to be named because the information isn't public.
Gas prices around Charlotte continue to climb and drivers are following the spike.
Gas prices have skyrocketed since Hurricane Harvey slammed into the Texas coast and shutdown refining and pipeline operations.
Retail U.S. gasoline prices rose 2.8 percent from Friday to Saturday as refineries warned customers about the fuel-supply shortage. These closures meant a loss of 2 million gallons of gasoline per day. Colonial said Line 1 of its pipeline, which carries gasoline, and Line 2, which mainly handles diesel and jet fuel, can return to action east of Lake Charles, Louisiana, as soon as refineries recover.
The disruption of almost a quarter of the nation's refining capacity has already led to a spike in gasoline prices.
Sandra Horton, manager of AAA operations in Raleigh, North Carolina, said the past week's price hikes have been "quite a bit of an increase for someone who might be planning their last weekend getaway for the holiday, the last weekend of summer". Today's average gasoline price in the Washington metro area is ten cents higher than it was a week ago. One commenter, Angela Flynn said, in part, "Just get gas like normal, all these people getting insane and getting more than normal is what is causing the shortage". Two refineries in the Gulf Coast region were operating at reduced rates. Exxon Mobil's Baytown refinery (capacity of 560,000 barrels a day) is also shut down. Major refineries in the country have been shut, the largest US pipeline of refined products has gone offline, crude oil production outages and logistical bottlenecks have led to a release from the Strategic Petroleum Reserve, and motorists will be pinched when filling up at the pump for some time.
