Reinstate SO 3355 streamlining NEPA reviews

“the new Administration must immediately reinstate the following Trump DOI secretarial orders: … SO 3355: Streamlining National Environmental Policy Reviews and Implementation of Executive Order 13807, “Establishing Discipline and Accountability in the Environmental Review and Permitting Process for Infrastructure Projects””
What has happened
- Partially done
Interior adopted the interim final rule as final, and announced it as the rescission of "more than 80% of Interior's prior NEPA regulations", with the majority moved into a Departmental NEPA Handbook of Implementing Procedures. **The Handbook has now been located and read (read-queue ticket 07, 2026-09-06), and it carries the substance of SO 3355 on one limb and not the other.** 516 DM 1, the DOI Handbook of NEPA Implementing Procedures (February 2026), sets the same 150-page ceiling on the text of an environmental impact statement that SO 3355 set in 2017 (300 pages for a proposed action of extraordinary complexity), adds a 75-page ceiling for environmental assessments, and requires the Responsible Official to certify on the face of each document that the bureau prioritized within those limits. That is the page limit restored, by a Handbook rather than by the order. The clock is not: SO 3355 set a one-year target for an environmental impact statement, and the Handbook's deadline is the statutory two years under NEPA section 107(g) (42 U.S.C. § 4336a(g)), with one year only where a sponsor has paid the section 112 expedited-review fee. Nor did SO 3355's other half survive: it implemented Executive Order 13807, revoked in 2021, and the Handbook implements the Fiscal Responsibility Act's limits instead. The order itself was not reinstated and has no page in Interior's Secretary's Orders library. One limb of two, so `partial` stands — but it is now `partial` on a read document rather than on an unlocated one.
- 516 DM 1, U.S. Department of the Interior Handbook of National Environmental Policy Act Implementing Procedures, February 2026 — § 2.4 page limits (150 pages, 300 for extraordinary complexity), § 1.5(d) (75 pages for an environmental assessment), §§ 1.5(e) and 2.5 deadlines
- Interior final rule: National Environmental Policy Act Implementing Regulations
- Interior press release: Trump Administration Delivers Historic NEPA Reform — rescission of more than 80% of Interior's NEPA regulations, procedures moved to a Departmental Handbook
- Interior ELIPS Secretary's Orders library — the published series runs to SO 3453 and carries no page for SO 3348, 3349, 3350, 3351, 3354, 3355, 3358, 3360, 3385 or 3389
- Attempted
Interior's interim final rule partially rescinded the Department's NEPA regulations and moved the remaining procedures into a Departmental Handbook outside the Code of Federal Regulations, citing the Supreme Court's holding that NEPA is a "purely procedural statute". A rewrite of the machinery SO 3355 operated on, not a reinstatement of the order.

Research notes
SO 3355 (August 31, 2017) set a 150-page ceiling and a one-year clock on Interior environmental impact statements. Interior has rewritten its NEPA procedures wholesale instead — see #1500, which carries the cost-disclosure half of the same ask, and #86 for the CEQ trail.
- Where the Handbook is (2026-09-06). It is not in Interior’s document library under an obvious name. Interior’s NEPA page (https://www.doi.gov/nepa) links to a landing page for the Handbook, and that page names the file: https://www.doi.gov/sites/default/files/documents/2026-02/doi-handbook-nepa-procedures-concluded-final-approval-publish-final.pdf. The file is 1.4 MB, PDF creation date 2026-02-27, titled “516 DM 1” and stamped “February 2026”.
- Same-instrument note. The Handbook is the shared citation for this item and for #1500. What it does to this Quote is restore SO 3355’s page ceiling without restoring its clock or the executive order it implemented; what it does to #1500’s is deliver that Quote’s “time and page limits” limb in full, because #1500 asks for limits rather than for this order. Both items’ notes say what the Handbook does to their own Quote.
