New Transport Refrigeration Unit Regulation in Development
California needs to reduce public health risk from Transport Refrigeration Units (TRU) near distribution centers and other facilities where TRUs and TRU generator sets congregate; as well as achieve emission reductions while in transit, especially near the most impacted communities. Improving freight efficiency and transitioning to zero- or near-zero emission technologies will help reduce toxic air contaminant emissions, criteria pollutant emissions, and GHG emissions.
TRUs are currently defined as refrigeration systems that are powered by internal combustion engines (inside the unit housing). They control the environment of temperature-sensitive products that are transported in refrigerated trucks, trailers, railcars and shipping containers. They may be capable of cooling or heating. TRUs are used to transport and store many products, including, but not limited to food, pharmaceuticals, plants, medicines, blood, chemicals, photographic film, art work, and explosives.
Some companies use TRUs for extended cold storage during the four- to six-week period before major holidays and events. Distribution centers and grocery stores are known to run out of cold storage space in their buildings, so they store overflow goods in TRU-equipped trucks and trailers outside the grocery stores and distribution centers. Distribution centers and other cold storage facilities also attract large volumes of TRUs that contribute to higher localized health risk in nearby communities. The new regulation is developing concepts to reduce emissions from facilities with TRU activity by transitioning to zero-emission operation where practical.
August 20, 2020: TRU Preliminary Cost Document
California Air Resources Board (CARB) staff is releasing preliminary cost inputs and assumptions to be used for the economic analysis of the Transport Refrigeration Unit (TRU) Regulation under development. This document is being released in advance of the Standardized Regulatory Impact Analysis (SRIA) and Initial Statement of Reasons (ISOR) for the TRU Regulation to support stakeholder input and the opportunity for staff to make revisions prior to publication of the SRIA and ISOR.
Please send comments or cost information to Lea Yamashita by September 10, 2020 to be considered prior to completion of the SRIA. Stakeholders can also continue to comment through the formal regulatory process.
