Appeals Court again deals major blow to Exxon's attempt to avoid responsibility for record-setting Clean Air Act violations

For Immediate Release:

NEW ORLEANS – In another stinging setback for ExxonMobil Corporation in a long-running environmental enforcement case, the federal 5th Circuit Court of Appeals rejected nearly every argument Exxon raised in its appeal of the $19.95 million penalty previously imposed by a federal trial court judge. That trial court punished the company for committing 16,386 days of violation of the federal Clean Air Act at its Baytown, Texas, refinery and chemical plant.  

The “crux of the dispute,” wrote Circuit Judge Gregg Costa for the three-judge appellate panel, is whether the environmental groups showed that every one of the thousands of proven violations was of a type or magnitude that was “capable of causing” the kinds of proven harms suffered by the groups’ members who live near the sprawling facility.

Judge Costa stated that, while the trial court’s findings established such “traceability” for a large number of violations – those involving flaring, smoke and haze, for example – the case is being sent back to the trial judge for the “limited purpose” of determining which of the remaining violations were also capable of causing the plaintiffs’ injuries and whether there should be any adjustment of the penalty amount.

“We are extremely pleased that the appeals court flatly rejected most of the claims Exxon raised in this appeal, and look forward to showing that the record penalty assessed by the district court fairly reflects the number and seriousness of the violations that clearly caused injuries in the Baytown community and beyond,” said National Environmental Law Center senior attorney Josh Kratka, part of the legal team representing Environment Texas and Sierra Club.

"Once again, the Fifth Circuit has ruled that Exxon broke the law and caused injury to the people of Baytown," said Luke Metzger, Executive Director of Environment Texas. "Today's ruling doesn't end the matter, but we're getting very close to finally holding Exxon accountable for their extensive record of illegal air pollution."

In rejecting other grounds for Exxon’s appeal, the appellate court found the plaintiffs had sufficiently proved they suffered injuries from Exxon’s violations that a court can remedy with a favorable decision, and that Exxon failed to prove its violations were excusable by the “affirmative defense” set up under Texas law. 

The appeals court did, however, also direct the trial court to reconsider whether an “act of God” defense is applicable to a relatively small number of violations occurring before and after Hurricane Ike in 2008.

This case follows successful cases in Texas the groups brought against: Shell Oil Company for violations at its Deer Park refinery; Chevron Phillips Chemical Company for violations at its Cedar Bayou chemical plant; and Pasadena Refining Systems, Inc. for violations at the Pasadena refinery. 

Exxon’s 3,400-acre complex in Baytown is located about 25 miles east of downtown Houston. Tens of thousands of people live within three miles of the facility. 

The groups are represented by the National Environmental Law Center; attorney David Nicholas of Newton, Mass.; and Houston attorneys Philip Hilder and Will Graham.


Sierra Club has approximately 24,000 members in Texas who are protecting parks and wildlands and building a clean energy future to protect human health and natural resources.   

Environment Texas advocates for clean air, clean water, and preservation of Texas’ natural areas on behalf of approximately 7,500 members statewide.
