A trio of South Texas organizations sued the Texas Commission on Environmental Quality (TCEQ) Monday, alleging the agency broke federal law by letting billionaire Elon Musk's SpaceX dump industrial wastewater without a permit. South Texas Environmental Justice Network, Carrizo/Comecrudo Nation of Texas and Save RGV sued TCEQ in Travis County District Court, arguing that a temporary permit the state issued for SpaceX to discharge contaminated water into wetlands violates the U.S. Clean Water Act. “The Clean Water Act requires the TCEQ to follow certain procedural and technical requirements when issuing discharge permits meant to protect public participation and ensure compliance with Texas surface water quality standards," Lauren Ice, an attorney for the groups, said in a statement.
