HR 4161

This bill, the Noise Mitigation Repair and Replacement Program Act, aims to provide additional funding to airports that have previously received federal grants for noise reduction efforts. It allows these airports to apply for supplemental funds to repair or replace soundproofing materials and equipment, particularly if increased aircraft noise necessitates a higher level of mitigation than originally planned. The bill also establishes a process for waiving certain requirements to facilitate these necessary upgrades, focusing on situations where existing mitigation has deteriorated or become ineffective.
