NEPA Update: FHWA issued two EV one-pagers with information on EVs and the National Environmental Policy Act (NEPA) and EVs and Categorical Exclusions to help practitioners navigate the environmental review process for EV infrastructure.

The National Environmental Policy Act (NEPA) establishes policy and goals for the protection, maintenance, and enhancement of the environment across the United States, and it provides a process for implementing these goals within federal agencies. NEPA was one of the first laws ever written that establishes the broad national framework for protecting our environment. Essentially, NEPA ensures that all branches of government consider the environment prior to undertaking any major federal action that significantly affects the environment.

When is NEPA required?

NEPA requirements are involved when airports, buildings, military complexes, highways, parkland purchases, and other federal activities are proposed. Activities include:

  • making decisions on permit applications
  • adopting federal land management actions
  • constructing highways and other publicly owned facilities

Who oversees the NEPA process?

The Council on Environmental Quality (CEQ) reviews and approves NEPA procedures, approves alternative arrangements for compliance with NEPA for emergencies, and helps to resolve disputes between Federal agencies, other governmental entities, and members of the public.

One of CEQ’s major responsibilities is to also develop and recommend national policies to the President that promote the improvement of environmental quality and meet the nation’s goals.

Why is NEPA important?

NEPA contains a Declaration of National Environmental Policy, which requires the federal government to use all practicable means to create and maintain conditions under which we can exist in productive harmony with nature. This ultimately means practicing environmental preservation and consideration.

Additionally, detailed statements assessing the environmental impact of proposed actions, as well as possible alternative actions, are created. These reports are in the forms of Environmental Assessments (EAs) and Environmental Impact Statements (EISs), and provide transparency to all proposed work. NEPA helps the public be informed of the potential impacts and alternatives involved in projects.
