Transport Refrigeration Unit Regulation
Document Type
NOP - Notice of Preparation

Document Description
Transport Refrigeration Units (TRU) subject to the proposed project are independently powered refrigeration systems designed to control the environment of temperature sensitive products transported in trucks, trailers, shipping containers, and railcars. TRUs and TRU generator sets emit diesel particulate matter, oxides of nitrogen, greenhouse gases, and other pollutants while in transit and during stationary operation. The proposed project may require truck TRUs to transition to zero-emission technology, trailer TRUs to utilize zero-emission operation while they are stationary for more than 15 minutes at applicable facilities, and applicable facilities to install electric charging or fueling infrastructure. Additionally, the project may require applicable TRUs to meet an emission standard, and applicable TRUs to use refrigerants with a global warming potential less than or equal to 2,200.
