250 R.I. Code R. 250-RICR-120-05-50.5

Current through December 26, 2024

Section 250-RICR-120-05-50.5 - Definitions

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.
