Represented an oil refiner in the defense of hundreds of class action property damage, personal injury and groundwater contamination claims arising from the largest land-based oil spill in Louisiana history, and at the time the largest oil spill in the U.S. since the Exxon Valdez. The oil spill was the result of widespread flooding associated with Hurricane Katrina, which caused a crude oil storage tank to breach and release thousands of gallons of crude oil in the neighboring residential community. The class certification hearing lasted a week and included the parties' presentation of multiple geotechnical, hydrological and mechanical experts. The claims area certified was much smaller than what the plaintiffs were seeking, resulting in a cost savings of hundreds of millions of dollars. The claims were successfully settled prior to trial.
