Sierra Club v. Tennessee Valley Authority

The federal district court for the Middle District of Tennessee ruled that the Tennessee Valley Authority (TVA) complied with the National Environmental Policy Act (NEPA) and Administrative Procedure Act when it issued a finding of no significant impact (FONSI) for a project that involved construction of 10 “highly efficient” natural gas combustion turbine units to replace older combustion turbines at a facility in Johnsonville, Tennessee. Regarding TVA’s consideration of greenhouse gas emissions, the court found that TVA’s no-action alternative analysis had properly included other events that might occur—including increased output at other TVA facilities—if the project did not occur. The court also found that TVA adequately considered potential impacts on upstream methane emissions in the gas supply chain and the project’s total greenhouse gas emissions. The court also deferred to TVA’s technical expertise in its choice of methodologies. In addition, the court found that TVA’s analysis of cumulative effects on greenhouse gas emissions was sufficient. The court also upheld TVA’s alternatives analysis, rejecting an argument that TVA should have considered an alternative proposed by the plaintiff that included solar, battery storage, and demand response. The court also rejected the contention that TVA was required to examine whether the project would meet climate goals set out in executive orders issued by President Biden.

The federal district court for the Middle District of Tennessee held that Sierra Club established associational standing to challenge Tennessee Valley Authority’s (TVA’s) decision to build a natural gas-fired power plant at an existing facility. Sierra Club alleged that TVA failed to adequately analyze climate change impacts, failed to adequately address greenhouse gas mitigation in light of executive orders to decarbonize the power sector, and failed to consider a reasonable range of alternatives. Sierra Club also alleged that TVA should have prepared an EIS for the project. The court found that a Sierra Club member’s alleged impacts from exposure to pollutants were sufficient to establish a concrete injury to satisfy associational standing requirements. The court concluded, however, that Sierra Club failed to establish organizational standing.
