              CHAPTER V--DEPARTMENT OF THE ARMY (CONTINUED)
 
PART 651--ENVIRONMENTAL ANALYSIS OF ARMY ACTIONS (AR 200-2)--Table of Contents
 
                Subpart F--Environmental Impact Statement
 
Sec. 651.44  Incomplete information.

    When the proposed action will have significant adverse effects on 
the human environment, and there is incomplete or unavailable 
information, the proponent will ensure that the EIS addresses the issue 
as follows:
    (a) If the incomplete information relevant to reasonably foreseeable 
significant adverse impacts is essential to a reasoned choice among 
alternatives and the overall costs of obtaining it are not exorbitant, 
the Army will include the information in the EIS.
    (b) If the information relevant to reasonably foreseeable 
significant adverse impacts cannot be obtained because the overall costs 
of obtaining it are exorbitant or the means to obtain it are not known 
(for example, the means for obtaining it are beyond the state of the 
art), the proponent will include in the EIS:
    (1) A statement that such information is incomplete or unavailable.
    (2) A statement of the relevance of the incomplete or unavailable 
information to evaluating the reasonably foreseeable significant adverse 
impacts on the human environment.
    (3) A summary of existing credible scientific evidence that is 
relevant to evaluating the reasonably foreseeable significant adverse 
impacts on the human environment.
    (4) An evaluation of such impacts based upon theoretical approaches 
or research methods generally accepted in the scientific community.
