The Environmental Protection Agency (EPA) has announced its decision to partially grant California's request to amend regulations for diesel-fueled Transport Refrigeration Units (TRUs). These amendments include various requirements, such as using specific refrigerants and transitioning to zero-emission refrigeration units. However, the EPA did not make a decision on the mandate for owners to switch a portion of their diesel truck TRU fleet to zero-emission technology by a specific date. The EPA's decision follows a review of California's standards to ensure they protect public health and comply with federal regulations.
Simple Explanation
The EPA decided to let California make some changes to the rules for special cooling machines in trucks that run on diesel, but they haven't yet decided if they will force owners to switch these machines to ones that don't pollute.
