(a) To the fullest extent possible, the District Engineer will prepare environmental documents concurrently with and integrated with analyses and related surveys and studies required by other Federal statutes. In appropriate instances, the District Engineer may participate in preparing single environmental assessment, finding of no significant impact, environmental impact statement, and Record of Decision documents.

(b) The District Engineer will combine an environmental document prepared in compliance with NEPA with any other agency document to reduce duplication and paperwork. Thus, the District Engineer may combine an environmental document with related plans, rules, or amendments as a single consolidated document.

(c) If comments on a notice of intent or other aspects of a scoping process identify consultations, permits, or licenses necessary under other environmental laws, the environmental document may contain a section briefly listing the applicable requirements and how the applicant has or will meet them (e.g., permits applied for or received, consultations initiated or concluded).
