A Categorical Exclusion (CE) is a classification under the National Environmental Policy Act (NEPA) that identifies actions that typically do not have a significant effect on the human environment. As a result, these actions do not require the preparation of an Environmental Assessment (EA) or an Environmental Impact Statement (EIS).
Legal Framework and Terminology
National Environmental Policy Act (NEPA)
NEPA, enacted in 1970, obligates federal agencies to evaluate the environmental effects of their proposed activities. The Council on Environmental Quality (CEQ) oversees NEPA compliance and establishes regulations and guidelines.
Definitions
- Environmental Assessment (EA): A document that provides evidence and analysis for determining whether to prepare an EIS or a Finding of No Significant Impact (FONSI).
- Environmental Impact Statement (EIS): A detailed written statement required for major federal actions significantly affecting the quality of the human environment.
- Finding of No Significant Impact (FONSI): A document that presents the reasons why an action will not have a significant effect on the human environment, thus not necessitating an EIS.
Criteria for Categorical Exclusion
Not all actions qualify for a CE. Agencies must adhere to specific criteria and guidelines established by the CEQ through the development of agency-specific NEPA procedures. For an action to qualify for a CE, it must:
- Lack Significant Environmental Impacts: The action must not individually or cumulatively have a significant environmental effect.
- Consistent with CEQ Guidelines: The action must align with established CEQ regulations and agency-specific NEPA procedures.
Examples of Categorical Exclusions
Some typical examples of actions that might qualify for a CE include:
- Routine maintenance and repair activities
- Administrative personnel activities
- Minor renovation of existing facilities
- Activities that do not lead to a change in land use or physical environment
Historical Context
Following NEPA’s establishment, federal agencies were required to identify and document specific activities that generally do not result in significant environmental impacts. This process led to the creation of CE lists in order to facilitate quicker and more efficient environmental reviews for minor actions.
Applicability in Environmental Assessments
By excluding certain routine actions from extensive environmental review, agencies can focus their resources on projects with potentially significant impacts. This streamlined process aids in efficient decision-making and reduces the burden of lengthy documentation and review.
Comparisons with EA and EIS
- EA: An EA requires analysis and documentation but is less comprehensive than an EIS.
- EIS: The most detailed level of documentation, requiring significant time and investment.
Related Terms
- NEPA: The overarching Act that governs environmental review processes for federal actions.
- CEQ (Council on Environmental Quality): The agency responsible for overseeing NEPA implementation.
- FONSI (Finding of No Significant Impact): Issued if an EA concludes no significant impacts.

Summary
Categorical Exclusion (CE) streamlines the environmental review process by exempting certain minor federal actions from requiring extensive documentation under an EA or EIS, thus facilitating efficient decision-making while upholding environmental protections in accordance with NEPA guidelines.
