Categorical Exclusion (CX) Determinations

Categorical exclusions are categories of actions that DOE has determined, by regulation, do not individually or cumulatively have a significant effect on the human environment and for which, therefore, neither an environmental assessment nor an environmental impact statement normally is required. DOE's categorical exclusions are listed in Appendices A and B to Subpart D of its NEPA regulations,10 CFR Part 1021.

Environmental Assessments (EA)

A concise public document that a Federal agency prepares under NEPA to provide sufficient evidence and analysis to determine whether a proposed agency action would require preparation of an environmental impact statement or a finding of no significant impact.

Environmental Impact Statements (EIS)

The detailed written statement that is required by section 102(2)(C) of NEPA for a proposed major Federal action significantly affecting the quality of the human environment.

Findings of No Significant Impact (FONSI)

A public document issued by a Federal agency briefly presenting the reasons why an action for which the agency has prepared an environmental assessment will not have a significant effect on the human environment and, therefore, will not require preparation of an environmental impact statement.

Mitigation Action Plans (MAP)

A document DOE prepares in accordance with DOE NEPA regulations (10 CFR 1021.331) that 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.

Notices of Availability (NOA)

A Notice of Availability (NOA) is a formal notice, published in the Federal Register, that announces the issuance and public availability of a draft or final EIS. The Environmental Protection Agency NOA is the official public notification of an EIS; a DOE NOA is an optional notice used to provide information to the public.

Notices of Intent (NOI)

A Notice of Intent (NOI) is a formal announcement of intent to prepare an EIS as defined in Council on Environmental Quality (CEQ) NEPA regulations (40 CFR 1508.22). DOE publishes NOIs in the Federal Register in accordance with DOE NEPA regulations (10 CFR 1021.311). Occasionally, DOE may publish an NOI to announce its intention to prepare an environmental assessment.

Records of Decision (ROD)

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 (See CEQ and DOE NEPA regulations at 40 CFR 1505.2 and 10 CFR 1021.315, respectively).

Supplement Analyses (SA)

A document that DOE prepares in accordance with DOE NEPA regulations (10 CFR 1021.314(c)) to determine whether a supplemental or new EIS should be prepared pursuant to CEQ NEPA regulations (40 CFR 1502.9(c).
