PFAS-Free Firefighting Foam Transition Reporting Act

S 1929 requires the Federal Aviation Administration (FAA) to submit biannual progress reports to Congress on transitioning certified airports (part 139 airports) to PFAS-free firefighting foam. Reports must detail guidance for airport operators, current foam stock levels, decontamination practices for equipment, and implementation timelines. The bill also mandates similar guidance for non-certified airports, with adjustments for their specific needs. Reporting continues until the FAA notifies Congress the transition plan is complete.
