(i) An adverse effect on public health or safety;
(ii) An adverse effect on federally listed endangered or threatened species, marine mammals, or critical habitat;
(iii) An adverse effect on archaeological resources or resources listed or determined to be eligible for listing in the National Register of Historic Places;

(v) A material violation of a Federal, state, or local environmental law by the FBI;
(vi) An effect on the quality of the human or natural environment that is likely to be highly scientifically controversial or uncertain, or likely to involve unique or unknown environmental risks;
(vii) Establishment of precedents or decisions in principle for future actions that have the potential for significant impacts (e.g., master plans, Integrated Natural Resource Management Plans, Integrated Cultural Resource Management Plans);
(viii) Significantly greater scope or size than normally experienced for a particular category of action;
(ix) Potential for substantial degradation of already existing poor environmental conditions. Also, initiation of a potentially substantial environmental degrading influence, activity, or effect in areas not already substantially modified; or
(x) A connection to other actions with individually insignificant, but cumulatively significant, impacts.
