The U.S. Environmental Protection Agency (EPA) awarded a $4,552,500 Project Grant under the Clean Heavy-Duty Vehicles Program (CFDA 66.049) to the Oxnard School District in California. This funding will support the replacement of 15 in-use, non-zero-emission heavy-duty vehicles with new zero-emission vehicles, such as electric school buses. The project aims to reduce air pollution and greenhouse gas emissions in EPA Region 9. Additionally, the grant will cover the purchase and installation of charging equipment, as well as workforce development and training to maintain, charge, fuel, and operate the new zero-emission vehicles. The Oxnard School District will serve as the subrecipient, managing the vehicle replacement, electrification, and community engagement activities. The anticipated outcomes include reduced emissions, fuel consumption, and maintenance costs, as well as improved air quality and student health in the Oxnard community.
