What GAO Found The Federal Aviation Administration (FAA) and Transportation Security Administration (TSA) work together to ensure the cybersecurity of the interconnected systems operating in the National Airspace System (NAS). FAA defined the roles and responsibilities of the entities responsible for carrying out the agency’s related goals and objectives. In contrast, TSA did not. TSA defined its goals and objectives for prioritizing cybersecurity within the agency and in the transportation systems sector in its 2018 Cybersecurity Roadmap. However, the roadmap is outdated and no longer aligned with the latest Department of Homeland Security Cybersecurity Strategy. The roadmap also does not..

Environmental Protection Agency | Proposed Rule | The Environmental Protection Agency (EPA) is proposing to approve a revision to the State of Wisconsin's State Implementation Plan (SIP) for the Oak Creek Power Plant located in Oak Creek, Wisconsin. The EPA is proposing to approve alternative nitrogen oxides (NO X ) emissions limits for the Oak Creek facility. The alternative limits will allow the facility to operate in compliance with State and Federal regulations, and emit less NO X over time as compared to current limits. This proposed action will not interfere with the National Ambient Air Quality Standards (NAAQS) and meets all applicable requirements under the Clean Air Act (CAA).

What GAO Found The Department of Justice’s Executive Office for Immigration Review (EOIR) conducts immigration court proceedings both in-person and using remote technology, such as WebEx—an internet-based video teleconferencing platform, or telephone. Per EOIR policy, immigration judges may use discretion to decide which, if any, remote medium is used by participants in a hearing. EOIR collects data on the medium used for each hearing, which reflects the location of only the judge and respondent. According to GAO’s analysis of this data, of the nearly 6 million hearings held from fiscal year 2022 through 2025, about 63 percent or 3.8 million hearings were in-person. Of the approximately 2.2.

What GAO Found The Department of Transportation (DOT) and its component agencies are underutilizing their office space department-wide based on the Utilizing Space Efficiently and Improving Technologies (USE IT) Act benchmark of 60 percent utilization. Specifically, GAO found that 89 percent of DOT’s 189 office buildings, including the DOT and the Federal Aviation Administration (FAA) headquarters complexes, were underutilized in August and September 2025 based on the USE IT benchmark. This was largely consistent with DOT’s USE IT Act reporting in March 2026. DOT’s underutilized office space costs hundreds of millions of dollars annually to lease, operate, and maintain. In August 2025, DOT..

What GAO Found As of September 2025, the Coast Guard reported about $448 million in environmental liabilities related to its shore infrastructure. This includes about $228 million for structures, like housing, presumed to be contaminated with asbestos-containing material or lead-based paint based on their age. It also includes about $220 million in cleanup projects at sites with a known or suspected release of contaminants. Several factors create uncertainty that could potentially lead to hundreds of millions of dollars of additional cleanup costs that the Coast Guard has not communicated to Congress. For example, the Coast Guard has identified properties which may be contaminated with “for.

Environmental Protection Agency | Proposed Rule | The U.S. Environmental Protection Agency (EPA) is proposing a Federal plan to implement the revised emission guidelines for existing other solid waste incineration (OSWI) units. The EPA promulgated emission guidelines for existing OSWI units in 2005 and revised the emission guidelines on June 30, 2025. If a State or Tribe with existing OSWI units subject to the 2025 revised OSWI emission guidelines does not submit an approvable plan by June 30, 2027, the EPA will develop, implement, and enforce a Federal plan for existing OSWI units located in that State or area of Indian Country. This action proposes a Federal plan to implement the 2025 rev.

What GAO Found The Department of Homeland Security (DHS) and Coast Guard leadership have made a case that the service needs transformation. Since 2019 GAO has reviewed four Coast Guard reform efforts and identified steps the service took to incorporate leading practices as well as gaps in key areas. For example, in prior reviews of Coast Guard sexual misconduct and modernization of mission planning and reserve component reform efforts, GAO found that the Coast Guard did not fully assess its workforce needs. Additionally, for two of the reform efforts, the Coast Guard did not fully establish goals and outcomes, making it difficult to determine if the reforms had the intended effects. Accordi.

What GAO Found In June 2025, GAO identified 21 priority recommendations for the Department of Transportation (DOT). Since then, DOT has implemented three of those recommendations. In June 2026, GAO identified an additional six priority recommendations and removed the priority status from two recommendations, bringing the total to 22. GAO is highlighting the following three areas that warrant timely and focused attention: Addressing workforce gaps, Improving grants management, and Integrating emerging technologies. Addressing GAO's recommendations in these areas would enhance DOT's efforts to: assess and address its mission-critical staffing and skills gaps; strengthen implementation of its..
