§333.11. Determining when NEPA applies. — Inbound Citations

(a) If the District Engineer determines under § 333.11 that NEPA applies to a proposed activity or decision, the District Engineer will then determine the appropriate level of NEPA review in the following sequence and manner. At all steps in the following process, the Corps will consider the proposed activity and its effects.

(1) If the Corps has established, or adopted pursuant to NEPA section 109, 42 U.S.C. 4336c, a categorical exclusion that covers the proposed activity, the District Engineer will analyze whether to apply the categorical exclusion to the proposed activity and apply the categorical exclusion, if appropriate, pursuant to § 333.14(e).

(2) If another agency has already established a categorical exclusion that covers the proposed activity, the District Engineer will consider whether to recommend that the Headquarters, U.S. Army Corps of Engineers adopt that exclusion pursuant to § 333.14(c) so that it can be applied to the proposed activity at issue, and so that Headquarters may consider applying to future activities of that type.

(3) If the proposed activity warrants the establishment of a new categorical exclusion, or the revision of an existing categorical exclusion, pursuant to § 333.14(b), the Chief of Engineers will consider whether to so establish or revise, and then apply the categorical exclusion to the proposed action pursuant to § 333.14(e).

(4) If the District Engineer cannot apply a categorical exclusion to the proposed activity consistent with paragraphs (a)(1)-(3), the District Engineer will determine the appropriate level of review, i.e., whether the proposed activity warrants preparation of an environmental assessment or an environmental impact statement. Most activities requiring a Corps permit that are not otherwise covered by a categorical exclusion normally require only an environmental assessment. In determining the level of review, the District Engineer will consider the proposed action's reasonably foreseeable effects consistent with paragraph (b), and then will:

(i) develop an environmental assessment, as described in § 333.15, if the proposed activity is not likely to have reasonably foreseeable significant effects or the significance of the effects is unknown; or

(ii) develop an environmental impact statement, as described in § 333.21, if the proposed activity is likely to have reasonably foreseeable significant effects.

(ii) Begin the NEPA process by determining whether NEPA applies, as described in § 333.11, and if it does, determine the appropriate level of NEPA review, as described in § 333.12, as soon as practicable after receiving the complete application

(a) If an activity is subject to NEPA, as determined following the procedures in § 333.11, and unless the District Engineer finds that the proposed activity is excluded from having to prepare an environmental assessment or environmental impact statement pursuant to a categorical exclusion as determined following the procedures in § 333.14, or by another provision of law, the District Engineer will prepare an environmental assessment with respect to the proposed activity that does not have a reasonably foreseeable significant effect on the quality of the human environment, or if the significance of such effect is unknown. District Engineers must follow Congress' direction that environmental assessments are to be “concise.” NEPA section 106(b)(2); 42 U.S.C. 4336(b)(2). The environmental assessment should normally be combined with any other required documents including Clean Water Act, section 404(b)(1) guidelines documentation, any applicable public interest review, any statement of findings, a finding of no significant impact or a determination that an environmental impact statement is required. Environmental assessment as used throughout this part normally refers to this combined document. When the environmental assessment is a separate document, it must be completed prior to completion of the statement of finding. The District Engineer may delegate the signing of the NEPA document. Should the environmental assessment demonstrate that an environmental impact statement is necessary, the District Engineer shall follow the procedures outlined in subpart C of this part. In those cases where an environmental impact statement is required, an environmental assessment is not required. However, the District Engineer must document their reasons for requiring an environmental impact statement.
