A categorical exclusion is a category of federal actions that may not require a detailed environmental assessment or impact statement under applicable procedures.
Definition
Under NEPA procedures, an agency may identify categories of actions that normally do not have significant environmental effects and therefore do not require an environmental assessment or environmental impact statement. The agency must determine whether a proposed action fits the applicable category and whether exceptions or extraordinary circumstances require further review. For a civil engineering firm, this classification can affect documentation needs, agency coordination, and schedule planning. A categorical exclusion is not automatic because a project seems routine, and it is not a permit or a finding that there are no environmental effects. The governing agency’s procedures and the facts of the action matter. Firms may support the agency or sponsor with technical information, but the agency makes the applicable determination. The EPA provides information on NEPA and environmental review.
How owners use it
- Confirm the relevant agency procedure and category before assuming a project qualifies for a categorical exclusion.
- Include supporting documentation and agency coordination in the scope when needed to establish eligibility.
- Reflect the agency’s determination and any follow-up requirements in the project record and schedule.
- A team checks the action against the applicable agency category and documents the agency’s decision before updating its review schedule.
