"It's been almost a week since service has been restored to Colonial Pipeline's Line #1, a major gasoline source for the southeast and Atlantic seaboard..." said Gregg Laskoski, senior petroleum analyst for GasBuddy. "While it appears that retail gas prices have peaked in 4 of the 6 states hit hardest (AL, GA, NC, SC, TN, VA) by the pipeline damage & shutdown, and those averages are now ebbing lower, statewide averages continue to climb in two states: Tennessee ($2.16/gal) and Virginia ($2.10/gal). Those states' averages were at $2.14 and $2.08 respectively on Sept. 20th, the day before service was restored.

"While it appears that the worst may be behind us, we're not out of the woods yet, where gasoline inventory levels are concerned," he added. "The overall drop in gasoline inventory tied to Colonial Pipeline was approximately 8.5 million barrels. To put that in perspective, in the two weeks following Hurricane Katrina, east coast gasoline inventories shed 3.3 million barrels."
