Environmental Reviews

TVA conducts environmental reviews in accordance with the National Environmental Policy Act, which requires federal agencies to consider the effects of their proposed projects on the human and natural environment before final decisions are made. These environmental reviews under NEPA typically also include assessments that facilitate compliance with other environmental review requirements such as those under the National Historic Preservation Act and the Endangered Species Act

Bat Conservation and Compliance

TVA’s bat strategy defines how we document and track our actions towards conserving bats. As part of the strategy, TVA completed an Endangered Species Act (ESA) programmatic consultation in 2018. This report describes TVA activities which could potentially impact endangered or threatened bats in the TVA Region (gray bat, Indiana bat, northern long-eared bat and Virginia big-eared bat). The consultation is effective for 20 years and ensures that TVA remains in compliance with the ESA.
