It all started just over two years ago, when an ExxonMobil pipeline burst in a neighborhood in Mayflower, AR.

Now the ExxonMobil Pipeline Company and Mobil Pipe Line Company (ExxonMobil) agreed to pay civil penalties, fund an environmental project and implement corrective measures to resolve violations of the Clean Water Act and state environmental laws stemming from the 2013 crude oil spill from the Pegasus Pipeline in Mayflower, said officials at the Department of Justice (DoJ) and the Environmental Protection Agency (EPA).

ExxonMobil will pay $3.19 million in federal civil penalties and take steps to address pipeline safety issues and oil spill response capability, according to a consent decree in federal court. In addition, ExxonMobil will pay $1 million in state civil penalties, $600,000 for a project to improve water quality at Lake Conway, and $280,000 to the Arkansas Attorney General’s Office for the state’s litigation costs.

The oil spill occurred on March 29, 2013, after the Pegasus Pipeline, carrying Canadian heavy crude oil from Illinois to Texas, ruptured in the Northwoods neighborhood of Mayflower, Arkansas.

Oil flowed through the neighborhood, contaminating homes and yards, before entering a nearby creek, wetlands and a cove of Lake Conway. Some residents had to evacuate their homes after the spill and remained displaced for an extended period of time. The spill volume was 3,190 barrels, or 134,000 gallons.

“This settlement holds ExxonMobil accountable for this very serious oil spill and its disastrous impact on the Mayflower community and environment,” said Assistant Attorney General John C. Cruden for the Justice Department’s Environment and Natural Resources Division. “This agreement is also an excellent example of federal and state cooperation that will benefit public health and the environment for years to come and most importantly prevent future disasters by requiring better pipeline safety and response measures.”

“Oil spills like this one in Mayflower, Arkansas have real and lasting impacts on clean water for communities,” said Assistant Administrator Cynthia Giles for EPA’s Office of Enforcement and Compliance Assurance. “Companies need to take the necessary precautions to make sure oil is transported safely and responsibly. This settlement puts in place essential pipeline safety and response measures that are important to make this industry safer for communities.”

“The U.S. and the state of Arkansas have worked together since the first barrel of oil was spilled in 2013 to provide relief and assistance to the residents of Mayflower and Faulkner County and to hold ExxonMobil accountable for this serious spill,” said U.S. Attorney Christopher R. Thyer for the Eastern District of Arkansas. “This settlement does both. In addition to paying significant civil penalties, ExxonMobil will provide money for safety and water-quality projects to help ensure that the residents of the affected area never have to go through an ordeal like this again. This resolution to a terrible disaster is a testament to the partnership between our federal and state governments to protect the citizens of Arkansas.”

“Pipeline companies have the responsibility to protect both our water resources and people from oil spills,” said Regional Administrator Ron Curry for EPA. “Today’s settlement will help protect the environment by preventing the high economic and environmental costs of future oil spills.”

The penalties owed by ExxonMobil under the consent decree are in addition to the money the company has already paid to reimburse federal and state response efforts and comply with orders and directives issued by the Pipeline and Hazardous Materials Safety Administration (PHMSA). The segment of the Pegasus Pipeline that includes the rupture site has not been in use since the March 2013 spill, and under the terms of the settlement agreement, ExxonMobil must comply with all PHMSA corrective action requirements before returning the pipeline to operation.

The consent decree also requires ExxonMobil to take other important pipeline safety corrective action to help prevent future ruptures and improve its spill response capabilities by providing additional training to its oil spill first responders. In addition, ExxonMobil must establish caches of spill response equipment and supplies at three strategically-chosen sites along the pipeline, including one location near Mayflower in Faulkner County, Arkansas.
