California Code of Regulations › Title 13 - Motor Vehicles › Division 3 - Air Resources Board › Chapter 1 - Motor Vehicle Pollution Control Devices › Article 4 - Diesel Particulate Matter Control Measures › Section 2020 - Purpose and Definitions of Diesel Particulate Matter Control Measures

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Purpose. Diesel
				  particulate matter was identified in 1998 as a toxic air contaminant. According
				  to California law, an airborne toxic control measure using the best available
				  control technology shall, therefore, be employed to reduce the public's
				  exposure to diesel particulate matter.
(b) Definitions. For the purposes of the
				  rules specified in article 4, the following definitions apply:
"Alternative fuel" means natural gas, propane, ethanol,
					 methanol, gasoline (when used in hybrid electric buses only), hydrogen,
					 electricity, fuel cells, or advanced technologies that do not rely on diesel
					 fuel. "Alternative fuel" also means any of these fuels used in combination with
					 each other or in combination with other non-diesel fuels.
"Commercially available" means available for purchase and
					 installation at a reasonable cost.
"Heavy-duty pilot ignition engine" means an engine designed
					 to operate using an alternative fuel, except that diesel fuel is used for pilot
					 ignition at an average ratio of no more than one part diesel fuel to ten parts
					 total fuel on an energy equivalent basis. An engine that can operate or idle
					 solely on diesel fuel at any time does not meet this definition.
"Level" means one of three categories of Air Resources
					 Board-verified diesel emission control strategies: Level 1 means the strategy
					 reduces engine diesel particulate matter emissions by between 25 and 49
					 percent, Level 2 means the strategy reduces engine diesel particulate matter
					 emissions by between 50 and 84 percent, and Level 3 means the strategy reduces
					 engine diesel particulate matter emissions by 85 percent or greater, or reduces
					 engine emissions to less than or equal to 0.01 grams diesel particulate matter
					 per brake horsepower-hour.
"Municipality" means a city, county, city and county,
					 special district, or a public agency of the State of California, and any
					 department, division, public corporation, or public agency of this State, or
					 two or more entities acting jointly.
"Owner" means the same as in title 13, California Code of
					 Regulations, section
					 2180.1(a)(25).
"Transit agency" means a public entity responsible for
					 administering and managing transit services. Public transit agencies can
					 directly operate transit service or contract out for all or part of the total
					 transit service provided.
"Terminal" means any place or places where a vehicle is
					 regularly garaged or maintained, or from which it is operated or dispatched,
					 which may include a private business or residence.
"Verified" means that a diesel emission control strategy or
					 system has received approval from the Executive Officer according to the
					 "Verification Procedure for In-Use Strategies to Control Emissions from Diesel
					 Engines" in title 13, California Code of Regulations, commencing with section
					 2700, and incorporated by
					 reference.
"Warranty Period" means the same as in title 13, California
					 Code of Regulations, section
					 2707.
