The National Environmental Policy Act (NEPA) requires TVA and other federal agencies to consider the impacts of its actions on the human environment before making decisions. The NEPA process is intended to help agency officials make better decisions that protect, restore and enhance the human environment. TVA’s NEPA procedures (PDF, 90kb) outline how TVA conducts these environmental reviews. 

On June 8, 2017, TVA initiated a process to amend these procedures and is seeking public input on the proposed amendments until September 6, 2017 (click here for more information). Until this process is complete, TVA will continue to implement its current procedures. 

TVA conducts three types of reviews under NEPA

  1. An Environmental Impact Statement (EIS) is prepared for major federal actions that have the potential for significant environmental impacts or public controversy. The EIS has multiple opportunities for public involvement.
  2. An Environmental Assessment (EA) is prepared if the action does not qualify for a categorical exclusion. TVA often prepares and EA describing anticipated environmental impacts. If the impacts are determined to be insignificant, a Finding of No Significant Impact (FONSI) is issued. If impacts are determined to be significant, TVA may dismiss the action, or issue an EIS and invite public involvement.
  3. Categorical Exclusions (CEs) are categories of actions that do not normally have, individually or cumulatively a significant impact on the environment and for which no unusual or exceptional circumstances exist. Neither an EA or an EIS is required for these actions, which are listed in TVA’s NEPA procedures (PDF, 90 kb).
