Airport Environmental Review Process (NEPA)

Airports

The National Environmental Policy Act (NEPA), and special purpose environmental laws and regulations, require environmental impact analyses of proposed airport actions that are subject to FAA decision. The environmental review process must be completed before a project commences.

Most airport environmental documents are prepared by airport sponsors. However, depending on the funding arrangement and level of impact, states that receive block grants for airport development or the FAA may prepare some documentation.

This page describes the main regulations, procedures, resources, data, and tools for the airport environmental review process.
