The Idaho Department of Environmental Quality (DEQ) offers rebates for the replacement of qualified medium- and heavy-duty diesel vehicles with new diesel or alternative fuel vehicles. Rebates are available for medium- and heavy-duty trucks; school, shuttle, and transit buses; freight switchers; airport ground support equipment; and forklifts and port cargo handling equipment. Vehicles must meet model year requirements, which vary by vehicle type. Funding amounts are based on vehicle type, fuel type (e.g., diesel, alternative fuel, all-electric), and applicant type (e.g., government, non-government). Funding is competitively awarded, and special consideration is given for projects located in air quality priority areas, areas with higher impact on sensitive populations, and oxides of nitrogen priority counties. First-round applications are due January 31, 2019. The program is funded by Idaho's portion of the Volkswagen Environmental Mitigation Trust. For more information, including program guidance and the application, see the DEQ Volkswagen Settlement website.
