                 CHAPTER VI--NATIONAL SCIENCE FOUNDATION
 
PART 641--ENVIRONMENTAL ASSESSMENT PROCEDURES FOR PROPOSED NATIONAL SCIENCE FOUNDATION ACTIONS IN ANTARCTICA--Table of Contents
 
Sec. 641.16  Preparation of environmental documents, generally.

    (a) Preparation of an environmental document. If the responsible 
official determines, either initially or on the basis of a preliminary 
environmental review, that a proposed action may have at least a minor 
or transitory impact on the Antarctic environment, he will prepare an 
environmental document in accordance with the provisions of this part. 
In making this determination, the responsible official should consider 
whether and to what degree the proposed action:
    (1) Has the potential to adversely affect the Antarctic environment;
    (2) May adversely affect climate and weather patterns;
    (3) May adversely affect air or water quality;
    (4) May affect atmospheric, terrestrial (including aquatic), glacial 
or marine environments;
    (5) May detrimentally affect the distribution, abundance or 
productivity or species, or populations of species of fauna and flora;
    (6) May further jeopardize endangered or threatened species or 
populations of such species;
    (7) May degrade, or pose substantial risk to, areas of biological, 
scientific, historic, aesthetic or wilderness significance;
    (8) Has highly uncertain environmental effects, or involves unique 
or unknown environmental risks; or
    (9) Together with other actions, the effects of any one of which is 
individually insignificant, may have at least minor or transitory 
cumulative environmental effects.

    (b) Prior assessments. Notwithstanding the provisions of 
Sec. 641.16(a), if (1) An environmental document (including a generic or 
programmatic CEE) or its equivalent has been prepared for a particular 
type of action; (2) That document includes an analysis of potential 
environmental effects that are directly relevant to the potential 
effects of the proposed action, taking in account factors such as the 
similarity of the actions and of the locations within which they take 
place; and (3) There are no potential site specific or other impacts 
that would require further evaluation, then a new environmental document 
need not be prepared. Instead, the responsible official shall prepare an 
Environmental Action Memorandum for the proposed action, cross-
referencing the previously prepared environmental document.
    (c) Exclusions. NSF has determined that the following actions will 
have less than a minor or transitory impact on the Antarctic 
environment, and are not subject to the procedures set forth in this 
part, except to the extent provided herein:
    (1) Scientific research activities involving:
    (i) Low volume collection of biological or geologic specimens, 
provided no more mammals or birds are taken than can normally be 
replaced by natural reproduction in the following season;
    (ii) Small-scale detonation of explosives in connection with seismic 
research conducted in the continental interior or Antarctica where there 
will be no potential for impact on native flora and fauna;
    (iii) Use of weather/research balloons, research rockets, and 
automatic weather stations that are to be retrieved; and
    (iv) Use of radioisotopes, provided such use complies with 
applicable laws and regulations, and with NSF procedures for handling 
and disposing of radioisotopes.
    (2) Interior remodelling and renovation of existing facilities.

Notwithstanding the foregoing, if information developed during the 
planning of any of the actions described in this paragraph (c) indicates 
the possibility that the action may have at least a minor or transitory 
impact on the Antarctic environment, the environmental effects of the 
action shall be reviewed to determine the need for the preparation of an 
environmental document.
    (d) Coordination with other committees, offices and federal 
agencies. The responsible official shall notify NSF's Committee of 
Environmental Matters when he intends to prepare an environmental 
document, and will coordinate preparation of the document with those 
entities. Responsibility for preparation of the environmental document 
rests primarily with the responsible official, but, as soon as is 
feasible, he should consult with and encourage the participation of 
other knowledgeable individuals within NSF, and, where appropriate, with 
other individuals, government agencies and entities with relevant 
knowledge and expertise.
    (e) Type of environmental document. The type of environmental 
document required under this part depends on the nature of the proposed 
action under consideration. An IEE must be prepared for proposed actions 
which the responsible official concludes may have at least a minor or 
transitory impact on the Antarctic environment and for which a CEE is 
not prepared. A CEE must be prepared if an IEE indicates, or if it is 
otherwise determined, that a proposed action is likely to have more than 
a minor or transitory impact on the Antarctic environment.
    (f) Obligation of funds. Because of logistic constraints (i.e., 
constraints due to transportation difficulties, inaccessibility of 
Antarctic bases for much of the year, and the need to obtain items or 
materials requiring long lead times), it may not be possible to complete 
the environmental review of a proposed action before funds must be 
committed and/or disbursed. In such cases, funds for the proposed action 
may be committed and/or disbursed, provided:
    (1) The appropriate environmental review is completed before 
implementation of the proposed action in Antarctica, and
    (2) Implementation plans for the proposed action will be modified or 
canceled, if appropriate, in light of the

completed environmental review (including public comments, if 
applicable).
