Federal regulators are assessing a $2.6 million civil penalty against ExxonMobil Pipeline Co. for a 2013 oil spill in Arkansas.
The Pipeline and Hazardous Materials Safety Administration on Thursday released its final report on the Pegasus pipeline leak. Roughly 3,190 barrels of oil spilled near Mayflower and Lake Conway. The agency's order said the company violated regulations governing the integrity of the line, along with its operation and maintenance.
The order also requires the company to update its pipeline assessments.
ExxonMobil said it was evaluating its options.
In August, a federal judge approved a $5 million agreement among the pipeline operator, the state of Arkansas and the federal government. ExxonMobil agreed to pay $3.19 million to the federal government and nearly $1.9 million in fines and other payments to Arkansas.
