## Abstract

On June 9, 1998, the Transportation Equity Act for the 21st Century (TEA-21) was enacted requiring the Federal Transit Administration (FTA) to establish the Clean Fuels Formula Grant Program (the program). The program was developed to assist non-attainment and maintenance areas in achieving or maintaining the National Ambient Air Quality Standards for ozone and carbon monoxide (CO). Additionally, the program supports emerging clean fuel and advanced propulsion technologies for transit buses and markets for those technologies. Although the program was authorized as a formula grant program from its inception, Congress did not fund the program. The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) changed the grant program from a formula-based to a discretionary grant program. The program, however, retains its initial purpose. FTA is publishing this final rule to revise the existing regulations to reflect the amendments made by SAFETEA-LU.
