Summary
Helps airports buy special equipment to test firefighting foam safely, which stops harmful chemicals called PFAS from getting into the ground and water.
What problem does this solve?
Testing firefighting foam at airports often releases harmful PFAS chemicals into the environment. This law solves the problem by paying the full cost for airports to get new equipment that tests the foam without spraying it.
What does this law do?
Provides 100% federal funding for testing equipment
Covers the full cost for airports to buy and install special equipment that tests firefighting foam systems without discharging the foam, preventing pollution.
Requires a study on reimbursing airports
Directs the FAA to report to Congress on options for paying back airports that already bought the safer testing equipment with their own money or with partial federal funds.
Sets a time limit on the funding
Makes the 100% cost share available for a limited time, ending five years after the law passes or sooner if the FAA changes its equipment eligibility rules.
Who does this affect?
- Airports
- Federal Aviation Administration (FAA)
- Communities near airports
What is the real world impact?
•
Protects the environment and public health
Prevents harmful 'forever chemicals' (PFAS) used in firefighting foam from contaminating soil and drinking water near airports during equipment testing.
•
Encourages adoption of safer technology
Removes the cost barrier for airports to switch to newer, safer testing equipment by providing full federal funding, making it easier for them to adopt environmentally friendly practices.
•
Addresses fairness for early adopters
Requires the FAA to explore ways to pay back airports that already bought the safer equipment without full federal help, though it does not guarantee reimbursement.
When does this start?
This law's funding rules apply to money made available in fiscal year 2023 and after, with several specific deadlines for agency action.
Airport outreach
Within 90 days of the law's passage (by March 20, 2023), the FAA must make airports aware of the new 100% funding opportunity.
Congressional briefing on reimbursements
Within 18 months of the law's passage (by June 20, 2024), the FAA must brief Congress on how it could potentially pay back airports that already bought the equipment.
