Categorical Exclusion (CX) Determinations

Categorical exclusions are categories of actions that a federal agency has determined, in its NEPA procedures, normally do not have a significant effect on the human environment and for which, therefore, neither an environmental assessment nor an environmental impact statement normally is required. A CX determination is the application of one or more CXs to a particular project or group of projects. There are 3 methods for DOE to make a CX determination.

  1. Most DOE CX determinations are based on the CXs listed in Appendices A and B to Subpart D of DOE’s NEPA regulations (10 CFR Part 1021). Those CX determinations are posted at DOE Categorical Exclusion (CX) Determinations.
  2. 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. See the Section 109: Adopting of Categorical Exclusions page.
  3. DOE may adopt another agency’s CX determination in certain instances. See the Adopted Categorical Exclusion (CX) Determinations page.

Environmental Assessments (EAs)

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 (EISs)

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 (FONSIs)

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 (MAPs)

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 Intent (NOIs)

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

Special Environmental Analyses (SEAs)

DOE prepares an SEA for certain emergency situations that demand immediate action.

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)).

Other Documents and Notices

NEPA-related documents and notices such as notices of availability, cancellation, and comment period extension; and interim action determinations.
