Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) The definitions
				  in Section
				  1900(b), Chapter
				  1, Title 13 of the California Code of Regulations are incorporated by reference
				  herein. The following definitions shall govern the provisions of this chapter:
(1) "Applicant" means the entity that has
				  applied for or has been granted verification under this Procedure
(2) "Average" means the arithmetic
				  mean.
(3) "Baseline" means:
(i) for uncontrolled engines, the emission
				  levels from the engine as tested without the LSI retrofit emission control
				  system implemented using the test cycle specified in this verification
				  procedure; and
(ii) for certified
				  engines, the emission standards to which the engine was
				  certified.
(4) "Certified
				  engine" means an engine manufactured in compliance with ARB or EPA emission
				  standards.
(5) "Durability" means
				  the ability of the applicant's LSI retrofit emission control system to maintain
				  a level of emissions at or below its verification emission level and maintain
				  its physical integrity over the durability periods specified in these
				  regulations. The minimum durability demonstration periods contained herein are
				  not necessarily meant to represent the entire useful life of the LSI retrofit
				  emission control system in actual service.
(6) "Emergency Engine Repair" means repair
				  conducted outside of normal scheduled maintenance that is required for the safe
				  operation of the equipment.
(7)
				  "Emission Control Group" means a set of LSI engines and applications determined
				  by parameters that affect the performance of a particular LSI retrofit emission
				  control system. The exact parameters depend on the nature of the LSI retrofit
				  emission control system and may include, but are not limited to, baseline or
				  certification levels of engine emissions, combustion cycle, displacement,
				  aspiration, horsepower rating, duty cycle, exhaust temperature profile, and
				  fuel composition. An applicant could specify an emission control group to be
				  comprised of engines from several different engine families, applications and
				  equipment manufacturers. Verification of an LSI retrofit emission control
				  system and the extension of existing verifications is done on the basis of
				  emission control groups.
(8)
				  "Executive Officer" means the Executive Officer of the Air Resources Board or
				  the Executive Officer's designee.
(9) "Executive Order" means the document
				  signed by the Executive Officer that specifies the verification level or
				  percentage reduction of an LSI retrofit emission control system for an emission
				  control group and includes any enforceable conditions and requirements
				  necessary to support the designated verification.
(10) "Hot Start" means the start of an engine
				  within four hours after the engine is last turned off.
(11) "LSI retrofit emission control system"
				  means any device or system employed with an in-use off-road LSI-engine vehicle
				  or piece of equipment that is intended to reduce emissions. Examples of LSI
				  retrofit emission control systems include, but are not limited to, closed-loop
				  fuel control system, fuel injection system, three-way catalysts, and
				  combinations of the above.
(12)
				  "LSI Retrofit Emission Control Group Name." See Section
				  2786(c)(2).
(13) "Off-Road Large Spark-Ignition Engine"
				  or "LSI Engine" means any spark ignition engine that produces a gross power of
				  greater than 19 kilowatts (25 horsepower) or is designed (e.g., through
				  fueling, engine calibrations, valve timing, engine speed modifications, etc.)
				  to produce greater than 19 kW ( >25 hp), and is used in an off-road vehicle
				  or equipment that is not excluded below. If an engine family has models at or
				  below 19 kW (25 hp) and models above 19 kW (25 hp), only the models above 19 kW
				  (25 hp) would be considered LSI engines. A spark ignition engine's operating
				  characteristics are significantly similar to the theoretical Otto combustion
				  cycle with the engine's primary means of controlling power output being to
				  limit the amount of air and fuel that is throttled into the combustion chamber
				  of the engine. LSI engines are designed for powering equipment applications
				  including, but not limited to, forklift trucks, sweepers, generators, and
				  industrial equipment and other miscellaneous applications. Specifically
				  excluded from this category are:
i) engines
				  operated on or in any device used exclusively upon stationary rails or
				  tracks;
ii) engines used to propel
				  marine vessels;
iii) internal
				  combustion engines attached to a foundation at a location for at least 12
				  months;
iv) off-road recreational
				  vehicles and snowmobiles; and
v)
				  stationary or transportable gas turbines for power
				  generation.
(14)
				  "Off-Road Vehicle" or "Off-Road Equipment" means any non-stationary device,
				  powered by an internal combustion engine or motor, used primarily off the
				  highways to propel, move, or draw persons or property including any device
				  propelled, moved, or drawn exclusively by human power. Examples include, but
				  are not limited to, marine vessels, construction/farm equipment, industrial
				  equipment, locomotives, small off-road engines, off-road motorcycles, and
				  off-highway recreational vehicles.
(15) "Otto Cycle Engine" means a type of
				  engine with operating characteristics significantly similar to the theoretical
				  Otto combustion cycle. The primary means of controlling power output in an Otto
				  cycle engine is by limiting the amount of air and fuel that can enter the
				  combustion chambers of the engine. As an example, gasoline-fueled and LPG
				  engines are Otto cycle engines.
(16) "Revoke" means to cancel the
				  verification status of an LSI retrofit emission control system. If an LSI
				  retrofit emission control system's verification status is revoked by the
				  Executive Officer, the applicant must immediately cease and desist selling the
				  LSI retrofit emission control system to end-users.
(17) "Verification" means that after the data
				  submitted has been thoroughly evaluated and an engineering judgment has
				  determined that an LSI Retrofit Emission Control System for installation on
				  in-use equipment will meet the requirements of this procedure, an Executive
				  Order is issued. This ensures the emissions reductions achieved by the control
				  strategy are real and durable and production units in the field achieve
				  reductions consistent with the verification procedure.
