"UPDATE: After this story was published, ExxonMobil updated the joint command incident report for Friday. The report now says that approximately 5,000 barrels of oil spilled in Mayflower.
Since ExxonMobil’s Pegasus pipeline ruptured and leaked Canadian oil across an Arkansas suburb a week ago, the company has maintained that only 'a few thousand barrels' spilled at the site.
'We've had no reason to change that at this stage,' Exxon spokesman Charles Engelmann told InsideClimate News on Friday.
But earlier this week in the corrective action order it issued, the Pipeline and Hazardous Materials Safety Administration (PHMSA), part of the Department of Transportation, said the spill was 3,500 to 5,000 barrels.
Engelmann said Friday that '3,500 to 5,000 is not our number' and suggested that InsideClimate News ask PHMSA where those figures came from. A PHMSA spokeswoman confirmed that the higher figures came from ExxonMobil Pipeline Company (EMPCO)."
