The bill establishes the "Unleaded Aviation Fuel Grant Program" within the New Mexico Department of Transportation, specifically managed by the aviation division. This program aims to provide competitive grants, not exceeding $200,000, to eligible applicants for the installation of unleaded aviation fuel dispensing systems at publicly owned airports that currently lack such facilities. Eligible applicants include publicly owned airports, political subdivisions of the state, and Indian nations, tribes, and pueblos. The aviation division will oversee the grant process, ensuring that funds are utilized promptly for the intended purpose.

Additionally, the bill creates the "Unleaded Aviation Fuel Grant Program Fund" as a nonreverting fund in the state treasury, which will consist of various financial sources such as appropriations and donations. The Department of Transportation is tasked with administering this fund, which is appropriated $5 million from the general fund for fiscal year 2026 and beyond. Any unspent balance at the end of a fiscal year will not revert to the general fund, allowing for continued support of the program's objectives.
