MORE American Fuel Act of 2026

Maddy summaryThe MORE American Fuel Act of 2026 amends the Atomic Energy Act to allow companies to begin constructing uranium enrichment facilities before the Nuclear Regulatory Commission issues an operating license, provided the application has been officially accepted and all federal laws are followed. This change shifts the licensing process from requiring approval before construction starts to a model where construction can proceed at the applicant's own financial risk while the regulatory review is still pending. To ensure local awareness, the bill mandates that applicants notify state governors, local government officials, and nearby tribal leaders at least 15 days before starting construction. The Nuclear Regulatory Commission is required to update its regulations within 180 days of the act's passage to reflect these new procedures, while retaining full authority to deny licenses if safety or operational standards are not met.

FEAT Act

Maddy summaryThe FEAT Act allows individuals involved in specific Department of Interior administrative proceedings to move their cases to a federal district court instead of having them heard solely by internal agency tribunals. This change applies to parties who either seek approval for certain conduct or are appealing sanctions and penalties imposed by the Department. Under the new rules, these parties must file for removal within 60 days of starting the action, and the federal court will review the case from scratch rather than relying on the agency's initial decision.

Cold Weather Diesel Reliability Act of 2026

Maddy summaryThe Cold Weather Diesel Reliability Act of 2025 requires the Environmental Protection Agency (EPA) to revise Clean Air Act regulations to address diesel vehicle challenges in extreme cold. It allows diesel vehicle manufacturers to temporarily disable engine power reductions or shutdowns caused by emissions system faults when temperatures are at or below freezing, but only until temperatures rise above freezing. The bill also grants a year-round exemption from diesel exhaust fluid (DEF) system requirements for vehicles primarily operating north of 59°N latitude or in regions with prolonged freezing conditions that make DEF use impractical. This exemption prevents engine derates or shutdowns due to DEF system issues, ensuring critical transportation and emergency services remain functional. The bill does not change overall emissions standards but provides targeted relief for safety and operational needs in cold weather regions.

The law does not apply to documents already exempt from public disclosure under the Freedom of Information Act (FOIA).
