A subsidiary of Exxon Mobil has filed court documents challenging the federal Pipeline and Hazardous Materials Safety Administration's authority to order safety measures following the March 2013 rupture of the company's Pegasus pipeline in central Arkansas.
The Arkansas Democrat-Gazette reports that Exxon Mobil Pipeline Co. also wants the court to overturn a $2.6 million fine that was paid by the company earlier this year.
The safety administration is to respond by Sept. 16.
Heavy crude oil spilled into a subdivision in the city of Mayflower when the pipeline cracked. Government attorneys have said the accident caused more than $57 million in property damage.
Oral arguments in the company's appeal are scheduled during the week of Oct. 31 in the 5th U.S. Circuit Court of Appeals in New Orleans.
