Categorical Exclusion (CX) Determinations
Categorical exclusions are categories of actions that a Federal agency has determined normally do not significantly affect the quality of the human environment and for which, therefore, neither an environmental assessment nor an environmental impact statement normally is required. When DOE determines that a proposed action fits within the requirements of one or more categorical exclusions, DOE issues a document called a categorical exclusion determination.
When a categorical exclusion is relevant to a proposed DOE action, DOE may take one of the following approaches:
DOE Categorical Exclusion (CX) Determinations: Most commonly, DOE makes a CX determination based on the CXs listed in Appendix B of DOE’s NEPA regulations (10 CFR Part 1021) or Appendix B of DOE's NEPA Implementing Procedures.
Section 109: Adopting of Categorical Exclusions: Section 109 of NEPA provides a method for a Federal agency to adopt a categorical exclusion listed in another agency’s NEPA procedures. If DOE adopts another agency’s CX, DOE may then make a CX determination based on the adopted CX.
Relied Upon Categorical Exclusion (CX) Determinations: DOE may rely upon another agency’s CX determination in certain instances.
Environmental Assessments (EAs)
A concise public document prepared by a Federal agency to support either a finding of no significant impact or a determination that an environmental impact statement is necessary (DOE NEPA Implementing Procedures, Section 6).
Environmental Impact Statements (EISs)
A detailed written statement for a proposed major Federal action significantly affecting the quality of the human environment (DOE NEPA Implementing Procedures, Section 7).
Findings of No Significant Impact (FONSIs)
A determination by a Federal agency that a proposed agency action does not require the issuance of an environmental impact statement (DOE NEPA Implementing Procedures, Section 6.5).
Mitigation Action Plans (MAPs)
A document DOE prepared in accordance with the DOE NEPA regulations prior to July 3, 2025 (10 CFR 1021.331). A MAP describes the plan for implementing commitments made in a DOE environmental impact statement and its associated record of decision, or, when appropriate, an EA or FONSI, to mitigate adverse environmental impacts associated with an action.
A Notice of Intent (NOI) is a public notice that an agency will prepare and consider an environmental document (DOE NEPA Implementing Procedures, Section 8.0). DOE prepares and publishes NOIs for environmental impact statements in accordance with NEPA, as amended, and DOE NEPA Implementing Procedures (Section 7.1). DOE may publish an NOI to announce its intention to prepare an environmental assessment (DOE NEPA Implementing Procedures, Section 6.1).
Decisions, Including Records of Decision (RODs)
A concise public document that records a Federal agency's decision(s) concerning a proposed action for which the agency has prepared an environmental impact statement (DOE NEPA Implementing Procedures, Section 7.9).
Special Environmental Analyses (SEAs)
DOE may prepare an SEA for certain emergency situations that demand immediate action (DOE NEPA Implementing Procedures, Section 4.4, and 10 CFR 1021.103).
A brief DOE document used to determine whether an existing environmental document should be supplemented, a new environmental document should be prepared, or no further NEPA documentation is required (DOE NEPA Implementing Procedures, Section 3.9).
NEPA-related documents and notices such as notices of availability, cancellation, and comment period extension; and interim action determinations.
