§ 2701. Definitions.

(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) "15 ppmw or less sulfur fuel" means diesel fuel with

a sulfur content equal to or less than 15 parts per million by weight (ppmw).

(2) "Alternative Diesel Fuel" means any fuel used in

diesel engines that is not commonly or commercially

known, sold or represented as diesel fuel No. 1- D or

No. 2-D, pursuant to the specifications in ASTM Standard Specification for Diesel Fuel Oils D975-81, and

does not require engine or fuel system modifications for

the engine to operate, although minor modifications

(e.g. recalibration of the engine fuel control) may enhance performance. Examples of alternative diesel fuels

include, but are not limited to, biodiesel, Fischer

Tropsch fuels, and emulsions of water in diesel fuel.

Natural gas is not an alternative diesel fuel. An emission control strategy using a fuel additive will be treated

as an alternative diesel fuel based strategy unless:

(A) The additive is supplied to the vehicle or engine

fuel by an on-board dosing mechanism, or

(B) The additive is directly mixed into the base fuel

inside the fuel tank of the vehicle or engine, or

(C) The additive and base fuel are not mixed until

vehicle or engine fueling commences, and no more additive plus base fuel combination is mixed than required

for a single fueling of a single engine or vehicle.

(3) "Approach Light System with Sequenced Flasher

Lights in Category 1 and Category 2 Configurations"

(ALSF-1 and ALSF-2) mean high intensity approach

lighting systems with sequenced flashers used at airports to illuminate specified runways during category II

or III weather conditions, where category II means a decision height of 100 feet and runway visual range of

1,200 feet, and category III means no decision height or

decision height below 100 feet and runway visual range

of 700 feet.

(4) "Applicant" means the entity that has applied for or

has been granted verification under this Procedure.

(5) "Auxiliary Emission Control Device" (AECD)

means any device or element of design that senses temperature, vehicle speed, engine revolutions per minute

(RPM), transmission gear, manifold vacuum, or any

other parameter for the purpose of activating, modulating, delaying, or deactivating the operation of the emission control system.

(6) "Average" means the arithmetic mean.

(7) "Backpressure Monitor" means a device that includes a sensor for measuring the engine backpressure

upstream of a hardware-based diesel emission control

system or component thereof installed in the exhaust

system and an indicator to notify the operator when the

backpressure exceeds specified high and in some cases

low backpressure limits, as defined by the engine manufacturer or the applicant for verification of a diesel

emission control strategy.

(8) "Baseline" means the test of a vehicle or engine

without the diesel emission control strategy implemented.

(9) "Cold Start" means the start of an engine only after

the engine oil and water temperatures are stabilized

between 68 and 86 degrees F for a minimum of 15

minutes.

(10) "Diesel emission control strategy" or "Diesel emission control system" means any device, system, or

strategy employed with an in-use diesel vehicle or piece

of equipment that is intended to reduce emissions. Examples of diesel emission control strategies include, but

are not limited to, particulate filters, diesel oxidation

catalysts, selective catalytic reduction systems, fuel additives used in combination with particulate filters, alternative diesel fuels, and combinations of the above.

(11) "Diesel Emission Control Strategy Family Name."

See Section 2706(g)(2).

(12) "Diesel Engine" means an internal combustion engine with operating characteristics significantly similar

to the theoretical diesel combustion cycle. The primary

means of controlling power output in a diesel cycle engine is by limiting the amount of fuel that is injected into the combustion chambers of the engine. A diesel

cycle engine may be petroleum-fueled (i.e., dieselfueled) or alternate-fueled.

(13) "Durability" means the ability of the applicant's

diesel emission control strategy to maintain a level of

emissions below the baseline and maintain its physical

integrity over some period of time or distance determined by the Executive Officer pursuant to these regulations. The minimum durability testing periods contained

herein are not necessarily meant to represent the entire

useful life of the diesel emission control strategy in actual service.

(14) "Emergency Standy Engine" means a diesel engine

operated solely for emergency use, except as otherwise

provided in airborne toxic control measures adopted by

the ARB.

(15) "Emergency Use" means using a diesel engine to

provide electrical power or mechanical work during any

of the following events and subject to the following

conditions:

(A) The failure or loss of all or part of normal electrical power service or normal natural gas supply to the

facility,

(B) The failure of a facility's internal power distribution system,

(C) The pumping of flood water or sewage to prevent

or mitigate a flood or sewage overflow,

(D) The pumping of water for fire suppression or protection,

(E) The powering of ALSF-1 and ALSF-2 airport

runway lights under category II or III weather conditions,

(F) Other conditions as specified in airborne toxic

control measures adopted by the ARB.

(16) "Emission control group" means a set of diesel engines and applications determined by parameters that

affect the performance of a particular diesel emission

control strategy. The exact parameters depend on the

nature of the diesel emission control strategy and may

include, but are not limited to, certification levels of engine emissions, combustion cycle, displacement, aspiration, horsepower rating, duty cycle, exhaust temperature

profile, and fuel composition. Verification of a diesel

emission control strategy and the extension of existing

verifications are done on the basis of emission control

groups.

(17) "Executive Officer" means the Executive Officer of

the Air Resources Board or the Executive Officer's designee.

(18) "Executive Order" means the document signed by

the Executive Officer that specifies the verification

level of a diesel emission control strategy for an emission control group and includes any enforceable conditions and requirements necessary to support the designated verification.

(19) "Fuel Additive" means any substance designed to

be added to fuel or fuel systems or other engine-related

systems such that it is present in-cylinder during combustion and has any of the following effects: decreased

emissions, improved fuel economy, increased performance of the entire vehicle or one of its component parts,

or any combination thereof; or assists diesel emission

control strategies in decreasing emissions, or improving

fuel economy or increasing performance of a vehicle or

component part, or any combination thereof. Fuel additives used in conjunction with diesel fuel may be treated

as an alternative diesel fuel. See Section 2701 (a)(2).

(20) "Hot Start" means the start of an engine within four

hours after the engine is last turned off. The first hot

start test run should be initiated 20 minutes after the

cold start for Federal Test Procedure testing following

Section 86.1327-90 of the Code of Federal Regulations,

Title 40, Part 86.

(21) "Portable Engine" means an engine designed and

capable of being carried or moved from one location to

another, except as defined in section 2701(a)(24). Engines used to propel mobile equipment of a motor

vehicle of any kind are not portable. Indicators of portability include, but are not limited to, wheels, skids, carrying handles, dolly, trailer, or platform. A portable engine cannot remain at the same facility location for

more than 12 consecutive rolling months or 365 rolling

days, whichever occurs first, not including time spent in

a storage facility. If it does remain at the facility for

more than 12 months, it is considered to be a stationary

engine. The definitions in Title 13 California Code of

Regulations section 2452(g) and section 2452(x) are incorporated by reference herein.

(22) "Regeneration", in the context of diesel particulate

filters, means the periodic or continuous combustion of

collected particulate matter that is trapped in a particulate filter through an active or passive mechanism. Active regeneration requires a source of heat other than the

exhaust itself to regenerate the particulate filter. Examples of active regeneration strategies include, but are

not limited to, the use of fuel burners and electrical

heaters. Passive regeneration does not require a source

of heat for regeneration other than the exhaust stream itself. Examples of passive regeneration strategies include, but are not limited to, the use of fuel additives

and the catalyst-coated particulate filter. In the context

of NOx reduction strategies, "regeneration" means the

desorption and reduction of NOx from NOx adsorbers

(or NOx traps) during rich operation conditions.

(23) "Revoke" means to cancel the verification status of

a diesel emission control strategy. If a diesel emission

control strategy's verification status is revoked by the

Executive Officer, the applicant must immediately

cease and desist selling the diesel emission control

strategy to end-users.

(24) "Stationary Engine" means an engine that is designed to stay in one location, or remains in one location. An engine is stationary if any of the following are

true:

(A) The engine or its replacement is attached to a

foundation, or if not so attached, will reside at the same

location for more than 12 consecutive months. Any engine that replaces engine(s) at a location, and is intended to perform the same or similar function as the engine(s) being replaced, will be included in calculating

the consecutive time period. In that case, the cumulative

time of all engine(s), including the time between the removal of the original engine(s) and installation of the

replacement engine(s), will be counted toward the consecutive time period; or

(B) The engine remains or will reside at a location for

less than 12 consecutive months if the engine is located

at a seasonal source and operates during the full annual

operating period of the seasonal source, where a seasonal source is a stationary source that remains in a single

location on a permanent basis (at least two years) and

that operates at that single location at least three months

each year; or

(C) The engine is moved from one location to another

in an attempt to circumvent the residence time requirements [Note: The period during which the engine is

maintained at a storage facility shall be excluded from

the residency time determination.] The definitions in

Title 13 California Code of Regulations section 2452(g)

and section 2452(x) are incorporated by reference

herein.

(25) "Verification" means a determination by the Executive Officer that a diesel emission control strategy

meets the requirements of this Procedure. This determination is based on both data submitted or otherwise

known to the Executive Officer and engineering judge13 CA ADC § 2701 Page 3
