The U.S. District Court for the Middle District of Louisiana ruled September19 that reheater replacements at a Louisiana power plant are not eligible for a routine maintenance exception under the Clean Air Act. The court’s ruling enables the Environmental Protection Agency and the Louisiana Department of Environmental Quality to advance a lawsuit claiming that Louisiana Generating LLC failed to install and run adequate pollution control equipment after modifications to its Big Cajun 2 power plant, in violation of the Clean Air Act and state law. The court argued that when a generating facility takes 25 days and spends $4.5 million to decrease forced outages and increase future generation, the work cannot be considered routine.
