The regulation applies to 53' or longer box-type trailers (dry van and refrigerated van) and tractors that pull them. Fleets with 20 or fewer box-type trailers may take advantage of a phase-in option by reporting trailer information by September 1, 2012. The deadline for fleets with 21 or more box-type trailers to register has already passed. Additionally, the regulation currently requires all 2011 model year tractors that pull 53' or longer box-type trailers and all 2011 model year 53' or longer box-type trailers to be SmartWay certified or be retrofitted to comply. Fleets that have 2011 model year equipment and qualify for the short haul or local haul exemptions must report information about their 2011 model year equipment now. Reporting of other tractors and trailers within the fleet is not required at this time.

Economic Hardship Language:

property of carbFleet owners that are financially unable to bring all of their vehicles into compliance can delay compliance for up to 3 heavier vehicles in the fleet that are required to meet PM BACT of section 2025(g), 2025(h), or 2025(i). The owner must report no later than January 31, 2015 to claim this option. The economic hardship extension will expire on January 1, 2017 The owner must submit a signed statement under penalty of perjury, that the owner does not have the financial means from personal and business accounts to bring any more vehicles into compliance, and the owner has not been approved for a loan since January 1, 2014 from any entity that could be used to bring the fleet into compliance.

SWCV Rule:

garbageCalifornia's solid waste collection vehicle rule was passed in September 2003 to reduce the harmful health impacts of exhaust from diesel-fueled waste collection trucks. The solid waste collection vehicle regulation (SWCV) will reduce cancer-causing particulate matter and smog-forming nitrogen oxide emissions from these trucks by requiring owners to use ARB verified control technology that best reduces emissions, following a phased-in schedule from 2004 through 2010.

Drayage Rule:

drayageThe Drayage Truck Regulation is part of the Air Resources Board's (ARB) ongoing efforts to reduce PM and NOx emissions from diesel-fueled engines and improve air quality associated with goods movement. In addition, this regulation also provides greenhouse gas benefits and is designed to support local emissions reduction goals such as the Clean Air Action Plan by the ports of Los Angeles and Long Beach and the Comprehensive Truck Management Program by the Port of Oakland.

TRU Rule:

reefer truckTransport Refrigeration Units (TRUs) are refrigeration systems powered by diesel internal combustion engines designed to refrigerate or heat perishable products that are transported in various containers, including semi-trailers, truck vans, shipping containers, and rail cars. Although TRU engines are relatively small, ranging from 9 to 36 horsepower, significant numbers of these engines congregate at distribution centers, truck stops, and other facilities, resulting in the potential for health risks to those that live and work nearby. Since diesel particulate matter has been identified as a toxic air contaminant, the ARB adopted an Airborne Toxic Control Measure (ATCM) for TRUs and TRU generator sets on February 26, 2004.

The ARB's Heavy-Duty Vehicle Inspection Program and Periodic Smoke Inspection Program were adopted into law in 1988 (Senate Bill 1997) and 1990 (Senate Bill 2330), respectively to control excessive smoke emissions and tampering from heavy-duty diesel trucks and buses. The regulations, title 13 CCR, sections 2180-2189 for HDVIP, and title 13 CCR, sections 2190-2194 for PSIP, governing these programs were last amended in 2007.

Heavy-Duty Diesel Emission Control Strategy Installation and Maintenance:

filterEvery day, on and off-road diesel engines create air pollutants that can adversely affect human health. ARB requires engine manufacturers to meet strict pollution standards for newer engines. However, fleet owners may need to install a verified diesel emission control strategy to clean up emissions from older, dirtier diesel engines. A diesel emission control strategy is a technology that, if maintained properly, reduces harmful air pollution from diesel engine exhaust before it is emitted into the air. The most common technology used is a diesel particulate filter (DPF), also known as a soot filter or DECS, which substitutes for the original factory muffler. ARB evaluates and approves DPFs to meet specific particulate matter or nitrogen oxide emission reductions.
