Two Major Lawsuits Filed Against ExxonMobil for Arkansas Tar Sands Spill
Cross-Posted from DeSmogBlog
Two major lawsuits were recently filed in the U.S. District Court for the Eastern District of Arkansas against ExxonMobil, the “private empire” behind the March 2013Pegasus tar sands pipeline spill of over 1.1 million gallons of diluted bitumen (“dilbit”) into the neighborhoods and waterways of Mayflower, AR, located in Faulkner County.
One is a class-action lawsuit filed by the Duncan Firm, Thrash Law Firm and Parker Waichman LLP on June 27. The other is a suit filed on June 13 by the U.S. Environmental Protection Agency (EPA) in concert with the Arkansas Attorney General’s Office, led by AG Dustin McDaniel.
Collectively, both lawsuits lay out the damning facts of the second biggest tar sands pipeline spill in U.S. history, caused by a 22-foot gash in the pipeline, second only to Enbridge’s “dilbit disaster” in Kalamazoo, Michigan. The cases also call for the spill’s victims – both people, government bodies and the ecosystem – to receive reparations.
Among other things, both suits clarify that ExxonMobil Pipeline Company dilbit has contaminated Lake Conway, the largest man-made lake in the United States, which serves as a tributary of the Arkansas River.
The class-action tort lawsuit slaps ExxonMobil with willful negligence under Arkansas state law, alleging Exxon knew Pegasus – built in the 1940’s far before the age of “extreme energy” and designed to carry light crude – would spill at some point. The suit also reveals for the first time that the spill was just the biggest of 13 other spills preceding it, meaning it was not just a spill out of the blue.
The joint EPA/Arkansas AG civil lawsuit cites Exxon for violating the Clean Water Act, Arkansas’ Hazardous Waste Management Act and Arkansas’ Water and Air Pollution Control Act.
Taken together, both suits keep the heat on ExxonMobil and on Alberta tar sandsproduction at-large as the battle over the proposed northern half of TransCanada’s Keystone XL tar sands pipeline heats up. U.S. President Barack Obama’s State Department is expected to make a decision on that pipeline’s fate in the next few months.
Class-Action Tort Lawsuit Lays Out Ecological Costs of Exxon’s Negligence
Arkansas’ class-action suit legally covers “all real property owners who have…property abutting Lake Conway…which has been physically contaminated and polluted by ExxonMobil’s toxic and dangerous Tar Sands released from ExxonMobil’s unsafe and deficient oil and gas pipeline.”
A major crux of the suit is that dilbit is more corrosive to pipelines than conventional crude, a fact ExxonMobil knew but allegedly disregarded for the sake of profit when proposing Pegasus’ flow reversal.
“Bitumen blends are more acidic, thick and sulfuric than conventional crude oil,” explains the suit. “[B]itumen contains 15 to 20 times higher acid concentrations than conventional crudes and five to ten times as much sulfur. Bitumen blends are 70 times more viscous…than conventional crudes. Additional sulfur, acid and viscosity in the bitumen leads to weakening or embrittlement of pipelines.”
In 2006, Pegasus underwent a transformation from a 20-inch pipeline carrying conventional light crude from Texas up to the northern U.S. into a dilbit line carrying Alberta’s tar sands from Patoka, IL to Nederlands, TX for refining on the Gulf Coast. The pipe wasn’t built to carry tar sands crude and was only meant to carry a maximum of 95,000 barrels of light crude per day, the suit explains, a fact Exxon allegedly knew but proceeded with the tar sands project anyway.
Exhibit A: Enbridge attempted to team up with Exxon in a joint venture partnership that would entail replacing the pipeline. Exxon turned down the deal and instead increased tar sands carrying capacity through the antiquated line to a level surpassing the maximum limit for light crude, an example the class-action cites as willful negligence.
