tru -- ARB Publishes TRU Advisory 12-24 on Flexibility Engines Posted: 05 Nov 2012 12:26:45
The California Air Resources Board (ARB or Board) has posted TRU Advisory 12-24 on the TRU Website. TRU Advisory 12-24 explains issues related to purchasing transport refrigeration units (TRU) equipped with flexibility engines after the Tier 4 Final (Tier 4f) new engine emissions standard for 25 to 50 horsepower (hp) engines goes into effect in 2013. More detailed information is provided in TRU Advisory 12-24, which is posted on the TRU Website at: http://www.arb.ca.gov/diesel/tru/tru.htm. Background: TRUs are refrigeration systems powered by integral diesel internal combustion engines designed to control the environment of temperature-sensitive products that are transported in trucks, trailers, shipping containers, and railcars. The emissions from these units are a source of unhealthful air pollutants including particulate matter, toxic air contaminants, nitrogen oxides, carbon monoxide, and hydrocarbons, and pose a potential threat to both public health and the environment. These units often congregate in large numbers at California distribution centers, grocery stores, and other facilities where they run for extended periods of time to ensure their perishable contents remain cold or frozen. These distribution and loading facilities are often in close proximity to schools, hospitals, and residential neighborhoods. In 2004, the TRU Regulation was adopted by the Board to reduce diesel particulate matter emissions from TRUs and TRU generator set engines. Amendments were adopted by the Board in November 2010 and October 2011. Questions related to the TRU ATCM, TRU Advisory 12-24, or registration of TRUs in ARBís Equipment Registration (ARBER) system may be emailed to firstname.lastname@example.org or called in to the TRU Help Line at: 1-888-878-2826.
