ExxonMobil Pipeline Co. v. United States Department of Transportation

ExxonMobil’s 859-mile long Pegasus Pipeline transports crude oil from Patoka, Illinois to Nederland, Texas. In March 2013, it ruptured, spilling several thousand barrels of oil near Mayflower, Arkansas. The Pipeline and Hazardous Materials Safety Administration, within the U.S. Department of Transportation, conducted an investigation and concluded that ExxonMobil violated several pipeline safety regulations under the Pipeline Safety Act, 49 U.S.C. 60101. Specifically, the agency found that the integrity management program (IMP) plan had not properly accounted for the risk of longitudinal seam failure and that this was a contributing factor in the Mayflower release. The agency assessed a $2.6 million civil penalty and ordered ExxonMobil to take certain actions to ensure compliance with those regulations. The Fifth Circuit vacated certain items in the order. Finding that it owed no deference to the agency’s interpretation of the regulation, the court concluded that ExxonMobil reasonably applied 49 CFR 195.452(e)(1)’s instruction to “consider” all relevant risk factors in making its pipeline susceptibility determination. The court remanded with an instruction to reevaluate the basis for the penalty associated with another violation. View "ExxonMobil Pipeline Co. v.
