32 CFR 651.13 - Classified actions.
(a) For proposed actions and NEPA analyses involving classified information, AR 380-5 (Department of the Army Information Security Program) will be followed.
(b) Classification does not relieve a proponent of the requirement to assess and document the environmental effects of a proposed action.
(c) When classified information can be reasonably separated from other information and a meaningful environmental analysis produced, unclassified documents will be prepared and processed in accordance with this part. Classified portions will be kept separate and provided to reviewers and decision makers in accordance with AR 380-5.
(d) When classified information is such an integral part of the analysis of a proposal that a meaningful unclassified NEPA analysis cannot be produced, the proponent, in consultation with the appropriate security and environmental offices, will form a team to review classified NEPA analysis. This interdisciplinary team will include environmental professionals to ensure that the consideration of environmental effects will be consistent with the letter and intent of NEPA, including public participation requirements for those aspects which are not classified.
