DOE set 500-plus regulations to expire. The docket disagreed

On May 29, 2026, the Department of Energy published a rule titled Zero-Based Regulating⧉ that wrote automatic expiration dates into 28 parts of Title 10 of the Code of Federal Regulations — over 500 regulations, by the count of 14 state attorneys general, spanning Office of Science grant rules, contractor whistleblower protection, Yucca Mountain siting guidelines, and nuclear-site security.▸ It issued the rule as a direct final rule — a procedure reserved for actions so routine that notice and comment would be pointless — stating it did "not anticipate significant public comments." The same document reports that OMB's regulatory review office had classified the action as significant. On July 9, 2026, DOE withdrew the rule in full⧉, "due to receipt of adverse comments" — 41 days after publication, four days before it would have taken effect. The sibling sunset rules at FERC⧉ and NRC⧉ survived the same gauntlet by carrying less: each lost exactly one provision to adverse comment and kept the rest. Their countdowns are running — FERC's regulations begin expiring December 5, 2026; NRC's on January 8, 2027.

Executive Order 14270⧉ (April 9, 2025) rests on a premise it states in one line: the Code of Federal Regulations "now approaches a staggering 200,000 pages," and regulations "linger in such volume that serious reexamination seldom occurs."▸ Its remedy inverts the default. Ten agencies and subcomponents — EPA, DOE, FERC, NRC, five Interior bureaus, and the Army Corps — were ordered to insert a Conditional Sunset Date into every regulation issued under listed energy statutes: existing rules expire one year after the sunset rule takes effect, new rules within five years, and no extension may ever run more than five years. Before anything expires, the agency must offer the public a chance to comment on the regulation's costs and benefits. The sunset rules themselves were to be effective "not later than September 30, 2025."

None made the date.▸ FERC's Order No. 914⧉ became effective December 5, 2025 — 66 days past the deadline — inserting sunset provisions into specified regulations across 12 parts of its code, the ones it called outdated, seldom used, or duplicative. NRC's Sunset Rule⧉ became effective January 8, 2026 — 100 days past — and was narrower still, excluding anything tied to its safety mandate or permitting regime. DOE's rule, covering the widest ground of the three, published 241 days past the deadline and never took effect at all.

The direct final rule⧉ worked by appending one section to each of 28 parts: "Sections in this part will automatically expire July 13, 2027, unless the section expires earlier, is rescinded, or the sunset provision is extended."▸ Twenty-one parts got that one-year fuse — among them the Office of Science's financial-assistance rules⧉ (part 605), the contractor-employee whistleblower program (part 708), civil penalties for classified-information violations (part 824), and the Yucca Mountain siting guidelines (parts 960 and 963). Seven security-related parts — the Human Reliability Program, restricted-data access, protective-force standards — were pre-extended to July 13, 2031, the Secretary having determined in the same document that created their expiration dates that an extension was already warranted.

A new part 1061 held the machinery, and the machinery runs section by section: "an affected section will automatically expire and cease to be effective on the identified conditional sunset date" unless the Secretary signs a written determination — published in the Federal Register, good for at most five years — that extension is warranted.▸ That is the labor the rule created for its own agency. Keeping the 500-plus tagged regulations alive would require determinations covering every one of them within twelve months. For scale: the Federal Register's own index counts 89 Energy Department final-rule documents in all of calendar 2025 — 14 of them FERC's. One determination can cover many sections, but the review behind each is the point of the exercise: the order's stated purpose is re-justification, not paperwork.

The rule's economics section is an absence.▸ Its Unfunded Mandates statement⧉ asserts no expenditures of $100 million or more in any year; its Paperwork Reduction Act statement asserts no new recordkeeping; its only forward-looking claim is that the sunset rule "is expected to generally result in decreased regulatory burdens" — a sentence with no number attached, in a rule whose subject is the mandatory cost-benefit re-examination of everyone else's regulations. The re-justification bill lands later, and elsewhere: NRC's June 26 request for information⧉ shows the mechanism running — the public is asked to "provide, to the extent possible, economic data to demonstrate the cost of complying with" 48 regulatory units that sunset January 8, 2027, in a comment window of 31 days.

It did not take a mass campaign.▸ As of July 13, the docket shows 22 submissions on the direct final rule and 32 on its companion proposal — 54 total. The decisive one arrived on deadline day, June 29: fourteen state attorneys general, led by California, arguing that a rule expiring 500-plus regulations cannot be "routine, insignificant in nature and impact, and inconsequential" — the legal standard for skipping notice and comment — and stating their comments were "significant and adverse, such that DOE must withdraw the DFR." Ten days later DOE did, in a two-column withdrawal notice⧉ that offers one sentence of reasoning: adverse comments were received.

FERC and NRC had already run this experiment at smaller scale, with the same certification — all three agencies used the identical sentence, that the agency "does not anticipate significant public comments on this rulemaking and considers it to be non-controversial."▸ All three anticipated wrong. FERC rescinded⧉ one sunset provision (smart-grid standards guidance, 18 CFR 2.27) after a single significant adverse comment. NRC withdrew⧉ its sunset on the post-9/11 aircraft-impact-assessment requirement for new reactors after adverse comments, then re-imposed it in April⧉ through ordinary notice-and-comment procedure — the requirement now lapses April 8, 2027 unless extended. The difference at DOE was not the procedure. It was the payload.

The record contradicts itself three times.▸ First, within the May 29 rule: section IV.B certifies non-controversy to dispense with notice and comment, while section IV.A reports that OIRA classified the action as a "significant regulatory action"⧉ under E.O. 12866 — a category for actions with major economic effects or novel legal issues. The attorneys general put it plainly: "DOE does not reconcile" the two. Second, between the rule and its docket: the anticipation of no significant comments was refuted by the agency's own July 9 withdrawal, which cites the comments as its only ground. Third, between the withdrawal and the rule it withdraws: the withdrawal notice⧉ describes the May 29 rule as having amended 10 CFR parts 451, 452, and 455 — parts the May 29 rule's heading and amendatory instructions never touched — and the withdrawal's own List of Subjects includes two of those three phantom parts while omitting the third.

The withdrawal is not the end of the docket.▸ The companion proposed rule⧉ — same 28 parts, same sunset provisions, published the same day — survives, and DOE has committed in the withdrawal to "respond to comments received by June 29, 2026, as part of any final action it takes on the parallel proposed rule." The clocks elsewhere run regardless: FERC's tagged regulations reach their conditional sunset December 5, 2026; NRC's 48 units reach theirs January 8, 2027, with the cost-benefit RFI closing July 27, 2026; the aircraft-impact requirement lapses April 8, 2027 unless extended. And DOE's re-engineering of its own rulemaking continued through the withdrawal week: on July 7 it proposed rewriting the Process Rule⧉ that governs how appliance-efficiency standards — regulations under one of the five statutes the sunset order covers — get made, with comments due August 6, 2026.
