National Environmental Policy Act (NEPA) Environmental Process

  • Intent to Study Letter – formal notification to adjacent businesses and residents that NDOT and FHWA intend to conduct environmental and preliminary engineering studies for a project. It is also to solicit public input to assist the project team in further identifying the purpose and need for the project, address concerns and potential impacts, and to be aware of potential mitigation measures.
  • Document the problems that need fixing. The Purpose & Need Statement documents why the project is needed.
  • Develop alternatives to be studied.
  • Solicit public and agency input throughout the environmental process. 
    • Impact Assessment Methodologies are prepared and made available so any concerns or questions may be answered before impact analysis begins. The Impact Assessment Methodologies have recently been updated based on additional coordination with resource agencies and information resulting from the impact assessment performed to date. Most of the changes are related to air quality. The revisions are shown using track changes for ease of review.
    • The Agency Coordination Plan documents the role local, state and federal agencies play in the study and lets agencies know when they will be asked to provide input.
    • The Agency Scoping Meeting allows NDOT to share project details and solicit agency input.
  • Prepare a document addressing the environmental impacts of the project.
  • Selection of an alternative to be implemented.
NEPA umbrella covers, air quality, environmental justice, visual character/aesthetics, hazardous materials, noise, water resources, community resources, vegetation, wildlife and fish, and cultural resources.
