PHOENIX (February 2, 2024) – The Maricopa County Air Quality Department (MCAQD) is pleased to announce that it is administering the Environmental Protection Agency's (EPA) Diesel Emission Reduction Act (DERA) State Clean Diesel Grant Program. This program aims to enhance air quality by replacing older diesel fleet vehicles with newer, cleaner burning technology.

Organizations within Maricopa or Yuma County may apply to receive a subaward for the retrofit, repower, or replacement of their older fleets (engine model year up to 2009) to new qualified diesel fleet vehicles or equipment. Organizations also have the option to replace fleet vehicles or school buses with model years 2010 or newer with new zero emission or low-NOx vehicles, including electric and hydrogen fueled vehicles.  

Applications must be submitted online by the end of the day on March 15, 2024. Funding is limited, with an estimated allocation of up to $1 million for the current award period. Subawards will be determined based on factors such as the reduction of pollutants, total project cost, vehicle use and technology, and the applicant's ability to complete the project by March 31, 2026. Award recipients will be announced in October 2024.

MCAQD is offering a virtual DERA Grant Writing Workshop on February 14, 2024, sponsored by Valley of the Sun Clean Cities Coalition, to assist interested parties with the grant application process.
