Sierra Club and Public Citizen are urging the D.C. Circuit to reject the Federal Energy Regulatory Commission’s decision to review only a 1,000-foot section of the 157-mile Saguaro Connector Pipeline. The groups argue FERC lacked evidence to support its claim that the pipeline would transport only Texas-produced gas, which affects its jurisdiction. They say the project should be reviewed in full, as its sole purpose is to export gas to Mexico. The case is ongoing.
