The Transportation Department hit oil giant Exxon Mobil on Wednesday with a proposed $2.6 million fine for a pipeline rupture in Arkansas earlier this year.
In March, the Pegasus pipeline operated by Exxon burst, spilling roughly 5,000 barrels of crude in Mayflower, Ark.
The notice released Wednesday by the Pipeline and Hazardous Materials Safety Administration said Exxon failed to act promptly in resolving pipeline failures prior to the spill.
Exxon did not follow operations and maintenance procedures, according to the administration notice.
