The Centers for Disease Control and Prevention (CDC) seeks broad public input on how data intermediaries can be used to support secure, scalable, standards-based public health data exchange. CDC invites public comment to inform the evaluation and to explore how data intermediaries can advance broader goals to prevent disease, detect emerging threats, drive state-of-the-art solutions that empower communities, and strengthen public health systems for a safer, healthier nation.

The Department of State revises its regulations governing the availability to the public of information that is under the control of the Department. This rule reflects changes in the Department's organization and procedures since the last revision of the Department's regulations on public access to information, including relating to the use of email to submit requests for information under this part.

The FAA proposes to adopt a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) Model CFM56-5B, CFM56-5C, and CFM56-7B engines with a certain high-pressure turbine (HPT) inner stationary seal installed. This proposed AD was prompted by multiple reports of honeycomb separation from the surface of HPT inner stationary seals. This proposed AD would require initial and repetitive borescope inspections (BSIs) of the rotating air HPT front seal for cracks and, depending on the results, replacement with a part eligible for installation. This proposed AD would also require removal and replacement of the affected HPT inner stationary seal. This proposed AD would also require inspection of the affected HPT inner stationary seal for honeycomb separation and, depending on the results of the inspection, removal and replacement of the rotating air HPT front seal, HPT rotor blades, and No. 3 ball bearing. The FAA is proposing this AD to address the unsafe condition on these products.

OFPP, DoD, GSA, and NASA (collectively referred to as the Federal Acquisition Regulatory Council or FAR Council) are proposing to amend the Federal Acquisition Regulation (FAR) to implement Executive Order (E.O.) 14275, Restoring Common Sense to Federal Procurement. The E.O. directs the elimination of excessive acquisition regulations to stop the inefficient use of American taxpayer dollars. The FAR Council is issuing twelve proposed rules that collectively, if finalized, would streamline the FAR in its entirety. This rule proposes revisions to FAR parts 9, 27, 47, and 52.

The National Institute of Standards and Technology (NIST) and the National Institute of Biomedical Imaging and Bioengineering (NIBIB), a part of the National Institutes of Health (NIH), are requesting input from stakeholders in order to gain a better understanding of the future needs for medical metrology and standards around medical imaging, devices, and diagnostics. This request for information is coordinated with a NIST/NIBIB Symposium on Medical Metrology and Standards for American Healthcare and Commerce Medical Imaging, Devices, Diagnostics at the joint NIST/University of Maryland Institute (UMD) for Bioscience and Biotechnology Research (IBBR). The input received will inform a joint NIST and NIBIB medical metrology and standards roadmap, a document that will identify future needs for medical metrology and standards, identify major stakeholders, and provide guidance for future government programs.

In this action, the U.S. Environmental Protection Agency (EPA) is supplementing its proposal to repeal all greenhouse gas (GHG) emission standards for fossil fuel-fired electric generating units (EGUs) to effectuate the best reading of Clean Air Act (CAA) section 111. We propose that CAA section 111 does not authorize the EPA to regulate emissions from power plants in response to global climate change concerns. For the multiple and independent reasons described herein, this additional rationale would also require rescinding the Administrator's contrary findings and determinations in 2015 and repealing all associated 2015 and 2024 GHG standards for the fossil fuel-fired EGU source category. In a separate action published concurrently with this supplemental notice, the EPA is finalizing the repeal of certain 2024 GHG standards for the fossil fuel-fired EGU source category on distinct legal and technical grounds. We are not reopening that final rule. Nor are we soliciting further comment on those issues through this supplemental notice, except to the extent that commenters believe the final rule bears on the distinct questions of statutory authority addressed herein.

In this final rule, the U.S. Environmental Protection Agency (EPA) is repealing most provisions of the 2024 Carbon Pollution Standards for greenhouse gas (GHG) emissions from fossil fuel-fired electric generating units (EGUs) based on a reevaluation of the best system of emission reduction for the relevant subcategories. Specifically, the EPA is repealing the emission guidelines for existing fossil fuel-fired steam generating units, the carbon capture and sequestration/storage (CCS)-based standards for coal-fired steam generating units undertaking a large modification, and the CCS-based standards for new base load stationary combustion turbines (i.e., Phase 2 standards). In a separate action published concurrently with this final rule, the EPA is issuing a supplemental proposal soliciting comment on additional reasons to rescind all GHG emission requirements for fossil fuel-fired EGUs to effectuate the best reading of Clean Air Act (CAA) section 111 and ensure consistency with applicable principles of administrative law beyond those reasons on which the EPA solicited comment in the June 2025 notice of proposed rulemaking.

The National Science Foundation (NSF) is reestablishing the Advisory Committee for Integrative Activities.

Based on affirmative final determinations by the U.S. Department of Commerce (Commerce) and the U.S. International Trade Commission (ITC), Commerce is issuing antidumping duty (AD) and countervailing duty (CVD) orders on L-lysine (lysine) from the People's Republic of China (China).

NASA, as part of its continuing effort to reduce paperwork and respondent burden, under the Paperwork Reduction Act (PRA), invites the general public and other Federal agencies to take this opportunity to comment on proposed and/or continuing information collections.

The Department of Homeland Security (DHS) proposes to remove regulations at 8 CFR 214.1(l)(2) to restore its previous and long- standing policy of not providing aliens in certain nonimmigrant classifications (and their dependents) with an up to 60-day grace period upon cessation of employment prior to the expiration of the alien's authorized period of stay. This proposal restores a direct relationship between an alien's nonimmigrant status and the specific employment or activity that formed the basis of his or her admission or grant of status in the United States and reduces administrative burden.

This final rule requires that a State Medicaid plan must provide that the Medicaid agency will not make payment under the plan for sex-rejecting procedures for children under 18, and prohibits the use of Federal Medicaid dollars to fund sex-rejecting procedures for individuals under the age of 18. In addition, this final rule requires that a separate State Children's Health Insurance Program (CHIP) plan must provide that the CHIP agency will not make payment under the plan for sex-rejecting procedures for children under 19, and prohibits the use of Federal CHIP dollars to fund sex-rejecting procedures for individuals under the age of 19. For Medicaid and CHIP beneficiaries who are actively receiving cross-sex hormone therapy, State Medicaid and CHIP agencies may continue to claim Federal Financial Participation for those hormone therapy medications for a period of up to 6 months from the effective date of this final rule.
