In July 2017, Wilson sued Formosa in federal court under a law that allows citizens to sue industrial polluters when government regulators fail to act. She and her co-plaintiffs, the San Antonio Bay Estuarine Waterkeepers, are seeking penalties of up to $184 million — $104,828 per day for every day Formosa was allegedly out of compliance with state and federal environmental permits and laws that require companies to report such violations.
