The Environmental Protection Agency (EPA) has extended the comment period for a draft risk assessment concerning Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS) in sewage sludge. Initially published on January 15, 2025, the public now has until August 14, 2025, to submit their comments. This extension grants additional time for stakeholders to review the document, which evaluates potential health and environmental risks related to the use and disposal of sewage sludge. The assessment aims to inform potential future regulations under the Clean Water Act.

The Federal Aviation Administration (FAA), part of the Department of Transportation, is proposing changes to the Class E airspace around Raleigh County Memorial Airport in Beckley, WV. This change is necessary because the older navigation system, the Beckley VOR, is being phased out. The proposal aims to update airspace rules to ensure flight safety and support local flight operations. Public comments on these proposed changes can be submitted until March 3, 2025.

The Department of Defense has announced a proposed arms sale to the Republic of Türkiye. This transaction includes the purchase of 40 new F-16 aircraft and the modernization of 79 existing F-16 jets, along with various related equipment, for an estimated cost of $23 billion. The sale supports U.S. foreign policy by enhancing Türkiye's capabilities, enabling it to better protect its airspace, participate in NATO missions, and maintain compatibility with U.S. and NATO forces. The sale will not affect the U.S. military balance, and the primary contractor will be Lockheed Martin.

On December 9, 2024, the Department of Energy (DOE) announced an extension of the comment period for their request for information about the Frontiers in AI for Science, Security, and Technology (FASST) initiative. Originally, the public could provide input until November 11, 2024, but due to high interest, the deadline has been extended to February 17, 2025. The FASST initiative aims to develop powerful AI systems for scientific research, energy, and security purposes. Participants can submit their comments by email to the DOE.

The Department of Defense has released a notification about an arms sale to Egypt. The sale includes a system designed to protect aircraft from infrared-guided missile attacks, with various equipment such as the Guardian Laser Turret Assemblies and Missile Warning Sensors. The total estimated cost of this sale is $104 million. This move is intended to enhance the security of Egypt, a strategic partner of the U.S. in the Middle East, without affecting the military balance in the region.

The Department of Transportation is seeking comments on proposed changes to existing forms used in the Railroad Rehabilitation and Improvement Financing (RRIF) and the Transportation Infrastructure Finance and Innovation Act (TIFIA) credit programs. These changes aim to simplify and streamline the application process for credit assistance, ensuring all requested information is necessary and aligned with current legal requirements. The Department invites public feedback on the necessity and effectiveness of these information collection activities, and how they can further enhance the quality and reduce the burden of collecting such information. Interested parties must submit their comments by April 11, 2025.

The Department of Transportation is seeking public comments on the modification of existing information collection activities related to the Railroad Rehabilitation and Improvement Financing (RRIF) and the Transportation Infrastructure Finance and Innovation Act (TIFIA) credit programs. These changes are intended to streamline the application process for these financial assistance programs. The department is asking for feedback on whether these data collection efforts are necessary, how accurate their burden estimates are, and how they might minimize the burden on respondents. Comments need to be submitted to the Office of Management and Budget by April 7, 2025.

The Consumer Product Safety Commission (CPSC) is seeking public comments on a new information collection request that involves a bathtub slip resistance study. This study aims to support the development of a voluntary safety standard for bathtubs and showers by measuring how slip-resistant they need to be. Participants will be recruited to step in and out of bathtubs while researchers measure the friction and movements of their feet. The objective is to prevent slip-related accidents, especially among older adults. Comments on this proposed study are open until March 7, 2025.

NASA has announced Phase 1 of the Deep Space Food Challenge, a competition aimed at developing innovative food production technologies for long-duration space missions. With a total prize of $500,000, NASA seeks to encourage the creation of systems that can provide nutritious and enjoyable food for astronauts on missions like those to the Moon, and potentially to Mars, with limited resupply from Earth. The challenge hopes to inspire solutions that can also address food production issues on Earth, especially in urban and remote environments. Up to 20 top U.S. teams may each receive a $25,000 prize and the chance to compete in a possible Phase 2.

The National Highway Traffic Safety Administration (NHTSA) has introduced new safety standards, called FMVSS Nos. 307 and 308, aimed at ensuring the safe use of hydrogen as a fuel source in vehicles. These rules set performance requirements for hydrogen fuel systems and storage to reduce the risk of fires and explosions. While the rules apply to most hydrogen-fueled vehicles, they exclude certain types like those with cryo-compressed or solid-state hydrogen storage systems. The standards are designed to align with international regulations but include some U.S.-specific adjustments to ensure testing is clear and objective.
