§ 51.14 Definitions. ( a ) As used in this subpart: *Categorical Exclusion* means a category of actions which do not individually or cumulatively have a significant effect on the human environment and which the Commission has found to have no such effect in accordance with procedures set out in § 51.22, and for which, therefore, neither an environmental assessment nor an environmental impact statement is required.
*Cooperating Agency* means any Federal agency other than the NRC which has jurisdiction by law or special expertise with respect to any environmental impact involved in a proposal (or a reasonable alternative) for legislation or other major Federal action significantly affecting the quality of the human environment. By agreement with the Commission, a State or local agency of similar qualifications or, when the effects are on a reservation, an Indian Tribe, may become a cooperating agency.
*Council* means the Council on Environmental Quality (CEQ) established by Title II of NEPA.
*DOE* means the U.S. Department of Energy or its duly authorized representatives.
*Environmental Assessment* means a concise public document for which the Commission is responsible that serves to: ( 1 ) Briefly provide sufficient evidence and analysis for determining whether to prepare an environmental impact statement or a finding of no significant impact.
( 2 ) Aid the Commission's compliance with NEPA when no environmental impact statement is necessary.
( 3 ) Facilitate preparation of an environmental impact statement when one is necessary.
*Environmental document* includes an environmental assessment, an environmental impact statement, a finding of no significant impact, an environmental report and any supplements to or comments upon those documents, and a notice of intent.
*Environmental Impact Statement* means a detailed written statement as required by section 102(2)(C) of NEPA.
*Environmental report* means a document submitted to the Commission by an applicant for a permit, license, or other form of permission, or an amendment to or renewal of a permit, license or other form of permission, or by a petitioner for rulemaking, in order to aid the Commission in complying with section 102(2) of NEPA.
*Finding of No Significant Impact* means a concise public document for which the Commission is responsible that briefly states the reasons why an action, not otherwise excluded, will not have a significant effect on the human environment and for which therefore an environmental impact statement will not be prepared.
*NEPA* means the National Environmental Policy Act of 1969, as amended (Pub. L. 91-190, 83 Stat. 852, 856, as amended by Pub. L. 94-83, 89 Stat. 424, 42 U.S.C. 4321, *et seq.*).

( 2 ) Any equipment or device, or important component part especially designed for such equipment or device, capable of separating the isotopes of uranium or enriching uranium in the isotope 235.
