Current through June 14, 2024
A. Unless otherwise expressly defined in this
				  section, the terms used in this regulation shall be defined by reference to
				  Part 0 (General Definitions) of this Subchapter. As used in this regulation,
				  the following terms shall, where the context permits, be construed as follows:
1. "Aerodynamic technologies" means
				  components designed to reduce wind resistance on the tractor or trailer
				  resulting in improved overall tractor fuel economy and reduced carbon dioxide
				  emissions. There are two main types of aerodynamic technologies: fairing and
				  flow control devices. US EPA SmartWay Technology Program verifies the
				  performance of certain categories of aerodynamic devices.
2. "California Air Resources Board" or "CARB"
				  means the California state agency established and empowered to regulate sources
				  of air pollution in California, including motor vehicles, pursuant to Division
				  26 (Air Resources) of the California Health & Safety Code.
3. "Clean alternative fuel conversion" means
				  a US EPA verified/certified technology system that allow gasoline or diesel
				  vehicles to operate on alternative fuels such as, but not limited to, natural
				  gas, propane, alcohol, or electricity.
4. "Diesel emission reduction solution" means
				  a US EPA verified technology used to reduce harmful pollutions of diesel
				  exhaust such as, but not limited to, selective catalytic reduction technologies
				  (SCRT), diesel particulate filters (DPF), and diesel oxidation catalyst
				  (DOC).
5. "Diesel engine" means a
				  compression ignition type of internal combustion engine.
6. "Diesel particulate matter filtration
				  system" or "DPFs" means a device that collects particulate matter in the
				  exhaust stream and oxidizes it into less harmful components using the high
				  temperature of the exhaust.
7.
				  "Engine repower" means the replacement of an old or original engine with a new
				  cleaner-running engine that is certified to a more stringent set of emissions
				  standards.
8. "Heavy-duty diesel
				  trailer truck" means any trailer truck defined by FHWA as Class 8 through Class
				  13.
9. "Idle reduction technology"
				  means a US EPA verified technology used to allow operators to shut down the
				  main drive or auxiliary engine such as, but not limited to, auxiliary power
				  units and generator sets (APU/GS), battery air conditioning systems (BAC), and
				  fuel operated heaters (FOH). US EPA's SmartWay Technology Program verifies the
				  performance of certain categories of idle reduction devices.
10. "Low rolling resistance tires" or "LRR"
				  means a tire that is designed to improve fuel efficiency of a tractor pulling a
				  trailer by minimizing its rolling resistance, which consists of the energy lost
				  as heat within the rubber itself, as well as aerodynamic drag of the tire, and
				  friction between the tire and the road and between the tire and the rim where
				  the tire is rolling under load; rolling resistance is expressed as the energy
				  consumed per until distance as the tire rolls under load. US EPA's SmartWay
				  Technology Program verifies the performance of new and retread low rolling
				  resistance tires.
11. "On-road use"
				  means vehicles that are intended by their manufacturer for use on public
				  highways. On-road vehicles must be certified by their manufacturer with the
				  U.S. Department of Transportation (DOT), National Highway Traffic
				  Administration (NHTSA), as compliant with on-highway safety standards as well
				  as certified to all applicable ARB and U.S. EPA on-road emission
				  standards.
12. "Routine
				  maintenance" means preventive or cyclical maintenance that is an essential part
				  of the on-going care and upkeep shown to improve fuel efficiency or decrease
				  emissions including, but not limited to, oil changes and cleaning of
				  DPFs.
13. "Transport refrigeration
				  unit" or "TRU" means a refrigeration systems powered by integral internal
				  combustion engines designed to control the environment of temperature-sensitive
				  products that are transported in trucks and refrigerated trailers. TRUs may be
				  capable of both cooling and heating.
14. "Transport refrigeration unit generator
				  sets" or "gensets" means a system used to provide electric power to
				  electrically driven refrigeration units of any kind.
15. "US EPA designated SmartWay tractor"
				  means a tractor that has been designated by the United States Environmental
				  Protection Agency (US EPA) as meeting the technical specifications and
				  requirements of the US EPA SmartWay Technology Program.
16. "US EPA SmartWay tractor-trailer" means
				  the baseline tractor-trailer with the SmartWay verified aerodynamic technology
				  installed on the trailer in its verified configuration.
17. "US EPA designated SmartWay trailer"
				  means a 53-foot or longer box-type dry van or refrigerated trailer that has
				  been designated by the US EPA as meeting the technical specifications and
				  requirements of the US EPA SmartWay Technology Program.
18. "US EPA SmartWay technology program"
				  means a voluntary program designed to assist fleets in identifying and
				  equipping the most fuel-efficient long-haul tractors and trailers available on
				  the market. The program helps carrier fleets make informed business decisions
				  to save fuel and improve their supply chain efficiency. SmartWay also verifies
				  the performance of idle reduction technology for locomotives and school
				  buses.
19. "Vehicle replacement"
				  means the replacement of an older vehicle with a newer vehicle certified to
				  more stringent emissions standards than the engine or vehicle being
				  replaced.
