Truck traffic and equipment operation in and around wholesale markets, warehouses and distribution centers across Massachusetts exposes workers at these facilities and neighbors to diesel emissions. The Department of Environmental Protection (MassDEP) is offering grants to owners of diesel-powered trucks and equipment servicing and operating at these facilities to buy and install three types of emission reducing technologies:

  • Auxiliary Power Units (APUs). These small diesel engines are installed on long-haul Class 8 trucks to provide cooling, heating and electricity so a truck's main engine can be shut down rather than idle when parked for extended periods.

  • Electric Transportation Refrigeration Units (eTRUs). These units are powered by land-based electrical infrastructure rather than diesel engines. More information: eTRU Grant Brochure  pdf format of eTRU Grant Brochure

  • Retrofit Devices. A variety of equipment can be installed in place of, or in-line with, a diesel engine's existing muffler to reduce emissions. More information: Retrofit Grant Brochure  pdf format of Retrofit Grant Brochure

The total available funding for technologies under Round II of the MassCleanDiesel: Clean Markets Program is approximately $275,000 and is provided by the federal Diesel Emissions Reduction Act (DERA) and other sources. MassDEP will award grants subject to the availability of funds and the quality of applications received.
