NEPA Questionnaires

Ensure your NEPA questionnaire is filled out correctly.

An NEPA questionnaire is often required by federal government agencies in order to ensure compliance with the National Environmental Policy Act (NEPA) 42 U.S.C. Section 4321 et seq. In all cases, a certified environmental/engineering professional must complete the required forms.

The NEPA survey helps identify if the site will require an environmental assessment (EA) or environmental impact statement (EIS). Assessments typically require a review of the following:

  • Wetlands.
  • Floodplains.
  • Sole source aquifer recharge area (designated by EPA).
  • Critical habitat or endangered/threatened species (listed or proposed).
  • Wilderness.
  • Coastal barrier in coastal barrier resources system or approved coastal zone management area.
  • Wild or scenic river.
  • Natural landmark.
  • Historical, archeological sites.

The questionnaire identifies if the proposed project will impact water quality, air quality, noise pollution, important land resources, unique natural features and areas, environmental justice, social and economic impacts and state environmental policy considerations.
