The Investigative Journal’s daily digest of notable entries in the Federal Register. Today’s edition, dated April 24, 2026 (Volume 91), runs to 118 separate documents — among them two rules formally designated significant under Executive Order 12866, a sweeping Pipeline and Hazardous Materials Safety Administration package that alone accounts for roughly a quarter of the day’s items, and a joint SEC–CFTC proposal to rewrite the confidential reporting form used to surveil the private-fund industry. This digest highlights the entries most likely to move markets, litigation, or public comment.
1. NRC codifies a “generic” environmental review for new reactors
The U.S. Nuclear Regulatory Commission published a final rule amending 10 CFR Part 51 to codify the findings of its new Generic Environmental Impact Statement for Licensing of New Nuclear Reactors (NUREG-2249). The rule, effective May 26, 2026, establishes a technology-neutral framework using a set of plant and site “parameters” to pre-resolve the environmental impacts that are common across reactor applications — leaving only site-specific issues for case-by-case review. The Commission is simultaneously issuing Revision 4 to Regulatory Guide 4.2 and an interim staff guidance document (COL-ISG-030) to align application practice with the new rule. The rulemaking carries Regulation Identifier Number 3150-AK55 and is listed as significant under EO 12866. (Federal Register document 2026-08015.)
The practical effect, as the rule’s preamble describes it, is to shorten the environmental review window for applicants pursuing combined licenses, early site permits, and construction permits by allowing them to incorporate the generic analysis by reference rather than re-litigate common impact categories. The NRC frames the move as part of an agency-wide effort to streamline licensing for advanced reactors — including small modular reactors — without sacrificing NEPA rigor.
The Commission emphasizes in the document that this action is “separate from” a broader structural overhaul underway pursuant to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” which directs a comprehensive review of NRC regulations, including those governing environmental analysis. Records suggest the generic EIS rulemaking had been in development since before EO 14300 was issued, but the two efforts are now running in parallel. For TIJ’s energy and accountability beats, the rule will be a benchmark against which to measure future agency decisions on reactor siting and the cost of first-of-a-kind builds.
2. PHMSA’s pipeline-safety omnibus: corrections, standards updates, and a bundle of NPRMs
The Pipeline and Hazardous Materials Safety Administration used today’s edition to publish a large slate of final rules, direct final rules, and proposed rules touching gas transmission, hazardous-liquid, and carbon-dioxide pipelines. The only PHMSA item formally flagged as EO 12866-significant is a correction (Doc. 2026-08058) to the agency’s 2019–2022 overhaul of the rules requiring operators to reconfirm the maximum allowable operating pressure, or MAOP, of long-haul gas transmission lines. The correction becomes effective August 3, 2026.
Alongside the correction, PHMSA issued more than a dozen direct final rules incorporating updated editions of industry standards by reference — ASTM A53, ASTM A333, ASTM D2513, ASTM F2620, NFPA 58, NFPA 59, ASME B31.4, MSS SP-75, NACE SP0206, NACE SP0502 and others — and several non-substantive final rules addressing consent orders, declaratory-order procedures, incident-reporting language, and electronic retention of Part 194 oil-spill response plans. Taken together, the package continues a multi-year effort to modernize PHMSA’s procedural regulations and to fold current industry consensus standards into the Code of Federal Regulations.
On the proposed-rule side, PHMSA posted a cluster of Notices of Proposed Rulemaking that are worth tracking for stakeholders. Among them: a proposal to allow remote-sensing right-of-way patrols using unmanned aerial systems and satellites (Doc. 2026-08080); a proposal to revise the timeframes for rupture-mitigation valves (Doc. 2026-08076); and a proposal to redefine “property damage” for purposes of triggering reportable-incident thresholds (Doc. 2026-08079). Comment periods for most of the NPRMs will run in parallel; operators, state agencies, and safety advocates such as Pipeline Safety Trust should review the full docket.
3. SEC and CFTC jointly propose to rewrite Form PF
The Commodity Futures Trading Commission and the Securities and Exchange Commission jointly proposed amendments to Form PF (Doc. 2026-07993), the confidential reporting form used by SEC-registered investment advisers to private funds — including hedge funds, private equity funds, and liquidity funds. Filings indicate the proposal would eliminate certain filing and reporting obligations, streamline others, and make corrections and conforming revisions. The proposal carries RINs 3235-AN64 (SEC) and 3038-AF68 (CFTC). Comments are due on or before June 23, 2026.
Form PF is one of the federal government’s principal windows into systemic risk in the private-fund industry. Data reported on the form feeds the Financial Stability Oversight Council’s monitoring of leverage, counterparty exposure, and liquidity mismatches in the roughly $27 trillion private-fund universe, according to publicly available FSOC materials. Any material trimming of the reporting fields would shrink that window. The Commissions frame the changes as burden reduction; investor-protection groups and former staff economists are likely to push back during the comment period.
For TIJ’s financial-accountability beat, the proposal is worth reading against the 2023 and 2024 Form PF expansions — which added Sections 5, 6, and 7 for stress-event and counterparty reporting — to determine whether the 2026 amendments effectively reverse those additions or merely streamline them. The 159-page preamble (Federal Register pages 22232–22391) should make the scope of the rollback measurable.
4. EPA proposes significant new use rules on a batch of TSCA chemicals
The Environmental Protection Agency proposed Significant New Use Rules (SNURs) under the Toxic Substances Control Act for a batch of chemical substances that were the subject of premanufacture notices and are already subject to EPA consent orders (Doc. 2026-08012, RIN 2070-AB27). The proposed SNURs would require any person — domestic or importing — to notify EPA at least 90 days before commencing manufacture or processing for any use designated “significant” in the rule. Comments close May 26, 2026.
SNUR 26-2 is the second such batch EPA has issued in 2026 and continues a standard TSCA workflow: chemicals introduced into U.S. commerce through the PMN process are channeled into targeted SNURs so that novel uses outside the conditions originally reviewed trigger a fresh agency assessment. Industry commenters typically focus on the breadth of the “significant new use” definition and on whether the 90-day window is workable; environmental groups focus on which exposure pathways were modeled in the underlying consent order.
5. DEA permanently schedules a synthetic cannabinoid
The Drug Enforcement Administration finalized placement of MDMB-4en-PINACA in Schedule I of the Controlled Substances Act (Doc. 2026-08104). The action, effective April 27, 2026, permanently controls the synthetic cannabinoid — chemically methyl 3,3-dimethyl-2-(1-(pent-4-en-1-yl)-1H-indazole-3-carboxamido)butanoate — along with its salts, isomers, and salts of isomers. DEA frames the rulemaking in part as a step toward meeting U.S. obligations under the 1971 Convention on Psychotropic Substances.
The rule imposes the full set of Schedule I controls — registration, quota, recordkeeping, security, import-export, and civil/criminal penalties — on anyone handling the substance for research, manufacture, distribution, or possession. For local prosecutors and state forensic labs, the federal scheduling completes a process that had been running on a temporary emergency-scheduling order; convictions and indictments that had been written around the temporary order can now proceed on the permanent listing.
6. OPM proposes to rewrite the Critical Position Pay Authority
The Office of Personnel Management proposed amendments to its regulations on the critical position pay authority (Doc. 2026-07996, RIN 3206-AP02). The draft rule would establish Executive Schedule Level I as the default maximum critical pay rate — with higher rates subject to written approval by the OPM Director — eliminate non-statutory caps and approval criteria, address the use of service agreements, and clarify that reductions or terminations of critical position pay are not “adverse actions” subject to grievance or appeal rights. Comments are due on or before May 26, 2026.
The critical-pay authority is a narrow Title 5 tool that lets agencies compensate senior technical experts above the General Schedule when recruiting for mission-critical roles. Data shows usage has historically been concentrated in cybersecurity, aviation-safety, and space-program positions. For accountability reporters, the proposed clarification that reductions in critical pay are not adverse actions is the most consequential change — it could alter the procedural rights of the small population of federal employees who hold these appointments.
7. Presidential memorandum: Board of Peace eligible to receive U.S. defense articles
A Presidential Memorandum (Doc. 2026-08126), dated April 8, 2026, and addressed to the Secretary of State, finds that furnishing defense articles and defense services to the “Board of Peace” will “strengthen the security of the United States and promote world peace.” The determination is made under Section 503(a) of the Foreign Assistance Act of 1961 and Section 3(a)(1) of the Arms Export Control Act, and directs the Secretary to transmit it and an accompanying justification memorandum to Congress.
The underlying justification memorandum referenced in the determination is not reproduced in the Federal Register text. The memorandum effectively adds the Board of Peace to the roster of international entities eligible to receive U.S. defense articles and services outside the standard country-to-country Foreign Military Sales channels — a category historically used for regional coalitions and multilateral bodies. Readers following U.S. foreign-security assistance should treat the classified justification memo, once transmitted to the House Foreign Affairs and Senate Foreign Relations committees, as the key document for verification.
8. DOT finalizes the one-page passenger-rights summary rule
The Department of Transportation finalized a rule (Doc. 2026-08103, RIN 2105-AE82) implementing Section 429 of the FAA Reauthorization Act of 2018. Covered U.S. air carriers must submit to DOT a one-page document summarizing passenger rights regarding delays, diversions, cancellations, baggage, and boarding, and must post that document in a prominent location on their websites within 90 days of submission. The rule is effective May 26, 2026, though compliance with the posting obligation is contingent on DOT’s completion of the Paperwork Reduction Act process.
The rule is narrower than the consumer-protection package the prior administration had pursued on airline refunds and ancillary-fee transparency, but it formalizes a readily enforceable disclosure regime. For TIJ’s consumer-accountability beat, the one-page summary becomes a useful compliance benchmark: once the required submissions land, any carrier that is not posting a version consistent with the DOT-submitted plan can be measured against its own filing.
Items relevant to TIJ’s investigative beats
Three threads from today’s edition merit follow-up reporting. First, the NRC’s nuclear-licensing rule is the clearest public marker yet of how the Commission intends to operationalize EO 14300; future investigative work should track which near-term applicants — particularly advanced-reactor vendors and utilities planning SMR builds — file the first applications that reference NUREG-2249. Second, the PHMSA cluster is a rare opportunity to audit a federal agency’s use of the “direct final rule” mechanism at scale in a single publication day; any substantive objection from a pipeline-safety advocate during the 60-day window would convert the affected DFRs into proposed rules. Third, the Form PF proposal will be the defining private-funds disclosure fight of the year; the public comment file at regulations.gov should be monitored for submissions from FSOC member agencies and former Office of Financial Research staff.
Also on the public-inspection list but not covered in depth above: an OSHA Operational Status Agreement with the Puerto Rico State Plan revising federal enforcement jurisdiction over marine-construction work on federal properties (Doc. 2026-08108); an NRC rule adjusting the cost-expenditure criteria for research-and-development utilization facilities (Doc. 2026-08024); and an FAA package of airworthiness directives covering Pratt & Whitney PW2000-series engines, Dassault Falcon 20 airframes, Bombardier Global 6000/6500 aircraft, Pilatus PC-12/47G airplanes, and B/E Aerospace medical seats.
