(a) The environmental consequences section forms the scientific and analytic basis for the comparisons under § 1502.14. It shall consolidate the discussions of those elements required by sections 102(2)(C)(i), (ii), (iv), and (v) of NEPA that are within the scope of the statement and as much of section 102(2)(C)(iii) of NEPA as is necessary to support the comparisons. This section should not duplicate discussions in § 1502.14. The discussion shall include:
(1) The environmental impacts of the proposed action and reasonable alternatives to the proposed action and the significance of those impacts. The comparison of the proposed action and reasonable alternatives shall be based on this discussion of the impacts.
(2) Any adverse environmental effects that cannot be avoided should the proposal be implemented.
(3) The relationship between short-term uses of man's environment and the maintenance and enhancement of long-term productivity.
(4) Any irreversible or irretrievable commitments of resources that would be involved in the proposal should it be implemented.
(5) Possible conflicts between the proposed action and the objectives of Federal, regional, State, Tribal, and local land use plans, policies and controls for the area concerned. (§ 1506.2(d) of this chapter)
(6) Energy requirements and conservation potential of various alternatives and mitigation measures.
(7) Natural or depletable resource requirements and conservation potential of various alternatives and mitigation measures.
(8) Urban quality, historic and cultural resources, and the design of the built environment, including the reuse and conservation potential of various alternatives and mitigation measures.
(9) Means to mitigate adverse environmental impacts (if not fully covered under § 1502.14(e)).
(10) Where applicable, economic and technical considerations, including the economic benefits of the proposed action.
(b) Economic or social effects by themselves do not require preparation of an environmental impact statement. However, when the agency determines that economic or social and natural or physical environmental effects are interrelated, the environmental impact statement shall discuss and give appropriate consideration to these effects on the human environment.
