# §4370m–4. Coordination of required reviews

- (a) **Concurrent reviews—** To integrate [environmental reviews](/usc/42/4370m.md?p=11) and [authorizations](/usc/42/4370m.md?p=3), each [agency](/usc/42/4370m.md?p=1) shall, to the maximum extent practicable—
  - (1) carry out the obligations of the [agency](/usc/42/4370m.md?p=1) with respect to a [covered project](/usc/42/4370m.md?p=6-A) under any other applicable law concurrently, and in conjunction with, other [environmental reviews](/usc/42/4370m.md?p=11) and [authorizations](/usc/42/4370m.md?p=3) being conducted by other cooperating or [participating agencies](/usc/42/4370m.md?p=17), including [environmental reviews](/usc/42/4370m.md?p=11) and [authorizations](/usc/42/4370m.md?p=3) required under [NEPA](/usc/42/4370m.md?p=16), unless the [agency](/usc/42/4370m.md?p=1) determines that doing so would impair the ability of the [agency](/usc/42/4370m.md?p=1) to carry out the statutory obligations of the [agency](/usc/42/4370m.md?p=1);
  - (2) formulate and implement administrative, policy, and procedural mechanisms to enable the [agency](/usc/42/4370m.md?p=1) to ensure completion of the [environmental review](/usc/42/4370m.md?p=11) process in a timely, coordinated, and environmentally responsible manner; and
  - (3) where an [environmental impact statement](/usc/42/4336e.md?p=6) is required for a [project](/usc/42/13641.md?p=2), prepare a single, joint interagency [environmental impact statement](/usc/42/4336e.md?p=6) for the [project](/usc/42/13641.md?p=2) unless the [lead agency](/usc/42/4336e.md?p=9) provides justification in the coordinated [project](/usc/42/13641.md?p=2) plan that multiple [environmental documents](/usc/42/4336e.md?p=5) are more efficient for [project](/usc/42/13641.md?p=2) review and [authorization](/usc/42/4370m.md?p=3).
- (b) **Adoption, incorporation by reference, and use of documents—**
  - (1) **Use of existing documents—**
    - (A) **In general—** On the request of a [project sponsor](/usc/42/4370m.md?p=18), a [lead agency](/usc/42/4336e.md?p=9) shall consider and, as appropriate, adopt or incorporate by reference, the analysis and documentation that has been prepared for a [covered project](/usc/42/4370m.md?p=6-A) under the laws and procedures of a [State](/usc/42/2021b.md?p=14) or Indian Tribe (as defined in [section 5130 of title 25](/usc/25/5130.md)) as the documentation, or part of the documentation, required to complete an [environmental review](/usc/42/4370m.md?p=11) for the [covered project](/usc/42/4370m.md?p=6-A), if the analysis and documentation were, as determined by the [lead agency](/usc/42/4336e.md?p=9) in consultation with the [Council](/usc/42/4336e.md?p=3) on Environmental Quality, developed pursuant to laws and procedures of that [State](/usc/42/2021b.md?p=14) or Indian Tribe (as so defined) that are of equal or greater rigor to each applicable Federal law and procedure, and prepared under circumstances that allowed for opportunities for public participation and consideration of alternatives, environmental consequences, and other required analyses that are substantially equivalent to what would have been available had the documents and analysis been prepared by a Federal [agency](/usc/42/4370m.md?p=1) pursuant to [NEPA](/usc/42/4370m.md?p=16).
    - (B) **Guidance by CEQ—** The [Council](/usc/42/4336e.md?p=3) on Environmental Quality may issue guidance to carry out this subsection.
  - (2) **NEPA obligations—** An [environmental document](/usc/42/4336e.md?p=5) adopted under [paragraph (1)](#b-1) or a document that includes documentation incorporated under [paragraph (1)](#b-1) may serve as the documentation required for an [environmental review](/usc/42/4370m.md?p=11) or a supplemental [environmental review](/usc/42/4370m.md?p=11) required to be prepared by a [lead agency](/usc/42/4336e.md?p=9) under [NEPA](/usc/42/4370m.md?p=16).
  - (3) **Supplementation of State documents—** If the [lead agency](/usc/42/4336e.md?p=9) adopts or incorporates analysis and documentation described in [paragraph (1)](#b-1), the [lead agency](/usc/42/4336e.md?p=9) shall prepare and publish a supplemental document if the [lead agency](/usc/42/4336e.md?p=9) determines that during the period after preparation of the analysis and documentation and before the adoption or incorporation—
    - (A) a significant change has been made to the [covered project](/usc/42/4370m.md?p=6-A) that is relevant for purposes of [environmental review](/usc/42/4370m.md?p=11) of the [project](/usc/42/13641.md?p=2); or
    - (B) there has been a significant circumstance or new information has emerged that is relevant to the [environmental review](/usc/42/4370m.md?p=11) for the [covered project](/usc/42/4370m.md?p=6-A).
  - (4) **Comments—** If a [lead agency](/usc/42/4336e.md?p=9) prepares and publishes a supplemental document under [paragraph (3)](#b-3), the [lead agency](/usc/42/4336e.md?p=9) shall solicit comments from other [agencies](/usc/42/4370m.md?p=1) and the public on the supplemental document for a period of not more than 45 days, beginning on the date on which the supplemental document is published, unless—
    - (A) the [lead agency](/usc/42/4336e.md?p=9), the [project sponsor](/usc/42/4370m.md?p=18), and any [cooperating agency](/usc/42/4336e.md?p=2) agree to a longer deadline; or
    - (B) the [lead agency](/usc/42/4336e.md?p=9) extends the deadline for good cause.
  - (5) **Notice of outcome of environmental review—** A [lead agency](/usc/42/4336e.md?p=9) shall issue a record of decision or [finding of no significant impact](/usc/42/4336e.md?p=7), as appropriate, based on the document adopted under [paragraph (1)](#b-1) and any supplemental document prepared under [paragraph (3)](#b-3).
- (c) **Alternatives analysis—**
  - (1) **Participation—**
    - (A) **In general—** As early as practicable during the [environmental review](/usc/42/4370m.md?p=11), but not later than the commencement of scoping for a [project](/usc/42/13641.md?p=2) requiring the preparation of an [environmental impact statement](/usc/42/4336e.md?p=6), the [lead agency](/usc/42/4336e.md?p=9) shall engage the [cooperating agencies](/usc/42/4336e.md?p=2) and the public to determine the range of reasonable alternatives to be considered for a [covered project](/usc/42/4370m.md?p=6-A).
    - (B) **Determination—** The determination under [subparagraph (A)](#c-1-A) shall be completed not later than the completion of scoping.
  - (2) **Range of alternatives—**
    - (A) **In general—** Following participation under [paragraph (1)](#c-1) and subject to [subparagraph (B)](#c-2-B), the [lead agency](/usc/42/4336e.md?p=9) shall determine the range of reasonable alternatives for consideration in any document that the [lead agency](/usc/42/4336e.md?p=9) is responsible for preparing for the [covered project](/usc/42/4370m.md?p=6-A).
    - (B) **Alternatives required by law—** In determining the range of alternatives under [subparagraph (A)](#c-2-A), the [lead agency](/usc/42/4336e.md?p=9) shall include all alternatives required to be considered by law.
  - (3) **Methodologies—**
    - (A) **In general—** The [lead agency](/usc/42/4336e.md?p=9) shall determine, in collaboration with each [cooperating agency](/usc/42/4336e.md?p=2) at appropriate times during the [environmental review](/usc/42/4370m.md?p=11), the methodologies to be used and the level of detail required in the analysis of each alternative for a [covered project](/usc/42/4370m.md?p=6-A).
    - (B) **Environmental review—** A [cooperating agency](/usc/42/4336e.md?p=2) shall use the methodologies referred to in [subparagraph (A)](#c-3-A) when conducting any required [environmental review](/usc/42/4370m.md?p=11), to the extent consistent with existing law.
  - (4) **Preferred alternative—** With the concurrence of the [cooperating agencies](/usc/42/4336e.md?p=2) with jurisdiction under Federal law and at the discretion of the [lead agency](/usc/42/4336e.md?p=9), the preferred alternative for a [project](/usc/42/13641.md?p=2), after being identified, may be developed to a higher level of detail than other alternatives to facilitate the development of mitigation measures or concurrent compliance with other applicable laws if the [lead agency](/usc/42/4336e.md?p=9) determines that—
    - (A) the development of the higher level of detail will not prevent the [lead agency](/usc/42/4336e.md?p=9) from making an impartial decision as to whether to accept another alternative that is being considered in the [environmental review](/usc/42/4370m.md?p=11); and

    - (A) the [lead agency](/usc/42/4336e.md?p=9), the [project sponsor](/usc/42/4370m.md?p=18), and any [cooperating agency](/usc/42/4336e.md?p=2) agree to a longer deadline; or
    - (B) the [lead agency](/usc/42/4336e.md?p=9), in consultation with each [cooperating agency](/usc/42/4336e.md?p=2), extends the deadline for good cause.
