This bill amends Title 49, United States Code, to establish a specific exception for the use of certain local general sales tax revenues. It clarifies that federal restrictions on how airport revenues must be spent do not apply to these particular sales taxes. The exemption allows a local government to use revenues from its generally applicable sales taxes for non-airport purposes, provided three strict conditions are met. These conditions include the local government having a sales tax that covered aviation fuel prior to December 9, 2014, not being a sponsor of a public airport, and having a large hub airport with over 35,000,000 enplanements in 2021 within its jurisdiction. This targeted amendment provides flexibility for a very limited set of local governments regarding the allocation of these specific sales tax funds.
