The lists of endangered species can be found in 50 CFR 17.11 (wildlife), 50 CFR 17.12 (plants), and

50 CFR 222.23(a) (marine organisms).

Note: Some states also list species as endangered. Thus, in certain cases a state definition

would also be appropriate.

63. ENRICHED URANIUM. Uranium whose content of the fissile isotope uranium-235 is greater than

the 0.7 percent (by weight) found in natural uranium. (See uranium and natural uranium.) [Derived

from 10 CFR 71, 49 CFR 173.403]

64. ENVIRONMENTAL ASSESSMENT (EA). A concise public document that a Federal agency

prepares under the National Environmental Policy Act (NEPA) to provide sufficient evidence and

analysis to determine whether a proposed agency action would require preparation of an

environmental impact statement (EIS) or a finding of no significant impact. A Federal agency may also

prepare an EA to aid its compliance with NEPA when no EIS is necessary or to facilitate preparation

of an EIS when one is necessary.

An EA must include brief discussions of the need for the proposal, alternatives, environmental impacts

of the proposed action and alternatives, and a list of agencies and persons consulted. (See finding of

no significant impact, environmental impact statement, and National Environmental Policy Act.)

[Derived from 40 CFR 1508.9, 10 CFR 1022.4(d)]

65. ENVIRONMENTAL IMPACT STATEMENT (EIS). The detailed written statement that is

required by section 102(2)(C) of the National Environmental Policy Act (NEPA) for a proposed

major Federal action significantly affecting the quality of the human environment. A DOE EIS is

prepared in accordance with applicable requirements of the Council on Environmental Quality NEPA

regulations in 40 CFR Parts 1500-1508, and the Department of Energy NEPA regulations in 10 CFR

Part 1021.

The statement includes, among other information, discussions of the environmental impacts of the

proposed action and all reasonable alternatives, adverse environmental effects that can not be avoided

should the proposal be implemented, the relationship between short-term uses of the human

environment and enhancement of long-term productivity, and any irreversible and irretrievable

commitments of resources. [Derived from 40 CFR 1500-1508]

66. ENVIRONMENTAL JUSTICE. The fair treatment and meaningful involvement of all people

regardless of race, color, national origin, or income with respect to the development, implementation,

and enforcement of environmental laws, regulations, and policies. Fair treatment means that no group

of people, including racial, ethnic, or socioeconomic groups, should bear a disproportionate share of

the negative environmental consequences resulting from industrial, municipal, and commercial

operations or the execution of Federal, state, local, and tribal programs and policies.
