                            Subpart A_General

 

Sec.  89.2  Definitions.



    The following definitions apply to part 89. All terms not defined 

herein have the meaning given them in the Act.

    Act means the Clean Air Act, as amended, 42 U.S.C. 7401 et seq.

    Adjustable parameter means any device, system, or element of design 

which is physically capable of being adjusted (including those which are 

difficult to access) and which, if adjusted, may affect emissions or 

engine performance during emission testing.

    Administrator means the Administrator of the Environmental 

Protection Agency or his or her authorized representative.

    Aircraft means any vehicle capable of sustained air travel above 

treetop heights.

    Amphibious vehicle means a vehicle with wheels or tracks that is 

designed primarily for operation on land and secondarily for operation 

in water.

    Auxiliary emission control device (AECD) means any element of design 

that senses temperature, vehicle speed, engine RPM, transmission gear, 

or any other parameter for the purpose of activating, modulating, 

delaying, or deactivating the operation of any part of the emission 

control system.

    Auxiliary marine diesel engine means a marine diesel engine that is 

not a propulsion marine diesel engine.

    Blue Sky Series engine means a nonroad engine meeting the 

requirements of Sec.  89.112(f).

    Certification means, with respect to new nonroad engines, obtaining 

a certificate of conformity for an engine family complying with the 

nonroad engine emission standards and requirements specified in this 

part.

    Compression-ignition means relating to a type of reciprocating, 

internal-combustion engine that is not a spark-ignition engine.



[[Page 42]]



    Constant-speed engine means an engine that is governed to operate 

only at rated speed.

    Crankcase emissions means airborne substances emitted to the 

atmosphere from any portion of the engine crankcase ventilation or 

lubrication systems.

    Emission control system means any device, system, or element of 

design which controls or reduces the emission of substances from an 

engine.

    Engine, as used in this part, refers to nonroad engine.

    Engine manufacturer means any person engaged in the manufacturing or 

assembling of new nonroad engines or importing such engines for resale, 

or who acts for and is under the control of any such person in 

connection with the distribution of such engines. Engine manufacturer 

does not include any dealer with respect to new nonroad engines received 

by such person in commerce.

    Engine used in a locomotive means either an engine placed in the 

locomotive to move other equipment, freight, or passenger traffic, or an 

engine mounted on the locomotive to provide auxiliary power.

    EPA enforcement officer means any officer or employee of the 

Environmental Protection Agency so designated in writing by the 

Administrator (or by his or her designee).

    Exhaust gas recirculation means an emission control technology that 

reduces emissions by routing exhaust gases that had been exhausted from 

the combustion chamber(s) back into the engine to be mixed with incoming 

air prior to or during combustion. The use of valve timing to increase 

the amount of residual exhaust gas in the combustion chamber(s) that is 

mixed with incoming air prior to or during combustion is not considered 

to be exhaust gas recirculation for the purposes of this part.

    Family emission limit (FEL) means an emission level that is declared 

by the manufacturer to serve in lieu of an emission standard for 

certification purposes and for the averaging, banking, and trading 

program. A FEL must be expressed to the same number of decimal places as 

the applicable emission standard.

    Full load governed speed is the maximum full load speed as specified 

by the manufacturer in the sales and service literature and 

certification application. This speed is the highest engine speed with 

an advertised power greater than zero.

    Gross power means the power measured at the crankshaft or its 

equivalent, the engine being equipped only with the standard accessories 

(such as oil pumps, coolant pumps, and so forth) necessary for its 

operation on the test bed. Alternators must be used, if necessary, to 

run the engine. Fans, air conditioners, and other accessories may be 

used at the discretion of the manufacturer, but no power adjustments for 

these accessories may be made.

    Identification number means a specification (for example, model 

number/serial number combination) which allows a particular nonroad 

engine to be distinguished from other similar engines.

    Intermediate speed means peak torque speed if peak torque speed 

occurs from 60 to 75 percent of rated speed. If peak torque speed is 

less than 60 percent of rated speed, intermediate speed means 60 percent 

of rated speed. If peak torque speed is greater than 75 percent of rated 

speed, intermediate speed means 75 percent of rated speed.

    Marine engine means a nonroad engine that is installed or intended 

to be installed on a marine vessel. This includes a portable auxiliary 

marine engine only if its fueling, cooling, or exhaust system is an 

integral part of the vessel. There are two kinds of marine engines:

    (1) Propulsion marine engine means a marine engine that moves a 

vessel through the water or directs the vessel's movement.

    (2) Auxiliary marine engine means a marine engine not used for 

propulsion.

    Marine vessel has the meaning given in 1 U.S.C. 3, except that it 

does not include amphibious vehicles. The definition in 1 U.S.C. 3 very 

broadly includes every craft capable of being used as a means of 

transportation on water.

    Model year (MY) means the manufacturer's annual new model production 

period which includes January 1 of the



[[Page 43]]



calendar year, ends no later than December 31 of the calendar year, and 

does not begin earlier than January 2 of the previous calendar year. 

Where a manufacturer has no annual new model production period, model 

year means calendar year.

    New for purposes of this part, means a nonroad engine, nonroad 

vehicle, or nonroad equipment the equitable or legal title to which has 

never been transferred to an ultimate purchaser. Where the equitable or 

legal title to the engine, vehicle, or equipment is not transferred to 

an ultimate purchaser until after the engine, vehicle, or equipment is 

placed into service, then the engine, vehicle, or equipment will no 

longer be new after it is placed into service. A nonroad engine, 

vehicle, or equipment is placed into service when it is used for its 

functional purposes. With respect to imported nonroad engines, nonroad 

vehicles, or nonroad equipment, the term new means an engine, vehicle, 

or piece of equipment that is not covered by a certificate of conformity 

issued under this part at the time of importation, and that is 

manufactured after the effective date of a regulation issued under this 

part which is applicable to such engine, vehicle, or equipment (or which 

would be applicable to such engine, vehicle, or equipment had it been 

manufactured for importation into the United States).

    Nonroad engine means:

    (1) Except as discussed in paragraph (2) of this definition, a 

nonroad engine is any internal combustion engine:

    (i) In or on a piece of equipment that is self-propelled or serves a 

dual purpose by both propelling itself and performing another function 

(such as garden tractors, off-highway mobile cranes and bulldozers); or

    (ii) In or on a piece of equipment that is intended to be propelled 

while performing its function (such as lawnmowers and string trimmers); 

or

    (iii) That, by itself or in or on a piece of equipment, is portable 

or transportable, meaning designed to be and capable of being carried or 

moved from one location to another. Indicia of transportability include, 

but are not limited to, wheels, skids, carrying handles, dolly, trailer, 

or platform.

    (2) An internal combustion engine is not a nonroad engine if:

    (i) the engine is used to propel a motor vehicle or a vehicle used 

solely for competition, or is subject to standards promulgated under 

section 202 of the Act; or

    (ii) the engine is regulated by a federal New Source Performance 

Standard promulgated under section 111 of the Act; or

    (iii) the engine otherwise included in paragraph (1)(iii) of this 

definition remains or will remain at a location for more than 12 

consecutive months or a shorter period of time for an engine located at 

a seasonal source. A location is any single site at a building, 

structure, facility, or installation. Any engine (or engines) that 

replaces an engine at a location and that is intended to perform the 

same or similar function as the engine replaced will be included in 

calculating the consecutive time period. An engine located at a seasonal 

source is an engine that remains at a seasonal source during the full 

annual operating period of the seasonal source. A seasonal source is a 

stationary source that remains in a single location on a permanent basis 

(i.e., at least two years) and that operates at that single location 

approximately three months (or more) each year. This paragraph does not 

apply to an engine after the engine is removed from the location.

    Nonroad equipment means equipment that is powered by nonroad 

engines.

    Nonroad vehicle means a vehicle that is powered by a nonroad engine 

as defined in this section and that is not a motor vehicle or a vehicle 

used solely for competition.

    Nonroad vehicle or nonroad equipment manufacturer means any person 

engaged in the manufacturing or assembling of new nonroad vehicles or 

equipment r importing such vehicles or equipment for resale, or who acts 

for and is under the control of any such person in connection with the 

distribution of such vehicles or equipment. A nonroad vehicle or 

equipment manufacturer does not include any dealer with respect to new 

nonroad vehicles or equipment received by such person in commerce. A 

nonroad vehicle or



[[Page 44]]



equipment manufacturer does not include any person engaged in the 

manufacturing or assembling of new nonroad vehicles or equipment who 

does not install an engine as part of that manufacturing or assembling 

process. All nonroad vehicle or equipment manufacturing entities that 

are under the control of the same person are considered to be a single 

nonroad vehicle or nonroad equipment manufacturer.

    Opacity means the fraction of a beam of light, expressed in percent, 

which fails to penetrate a plume of smoke.

    Operating hours means:

    (1) For engine storage areas or facilities, all times during which 

personnel other than custodial personnel are at work in the vicinity of 

the storage area or facility and have access to it.

    (2) For all other areas or facilities, all times during which an 

assembly line is in operation or all times during which testing, 

maintenance, service accumulation, production or compilation of records, 

or any other procedure or activity related to certification testing, to 

translation of designs from the test stage to the production stage, or 

to engine manufacture or assembly is being carried out in a facility.

    Post-manufacture marinizer means a person who produces a marine 

diesel engine by substantially modifying a certified or uncertified 

complete or partially complete engine, and is not controlled by the 

manufacturer of the base engine or by an entity that also controls the 

manufacturer of the base engine. For the purpose of this definition, 

``substantially modify'' means changing an engine in a way that could 

change engine emission characteristics.

    Presentation of credentials means the display of the document 

designating a person as an EPA enforcement officer or EPA authorized 

representative.

    Propulsion marine diesel engine means a marine diesel engine that is 

intended to move a vessel through the water or direct the movement of a 

vessel.

    Rated speed is the maximum full load governed speed for governed 

engines and the speed of maximum horsepower for ungoverned engines.

    Spark-ignition means relating to a gasoline-fueled engine or other 

engines with a spark plug (or other sparking device) and with operating 

characteristics significantly similar to the theoretical Otto combustion 

cycle. Spark-ignition engines usually use a throttle to regulate intake 

air flow to control power during normal operation.

    Specific emissions means emissions expressed on the basis of 

observed brake power, using units of g/kW-hr. Observed brake power 

measurement includes accessories on the engine if these accessories are 

required for running an emission test (except for the cooling fan). When 

it is not possible to test the engine in the gross conditions, for 

example, if the engine and transmission form a single integral unit, the 

engine may be tested in the net condition. Power corrections from net to 

gross conditions will be allowed with prior approval of the 

Administrator.

    Sulfur-sensitive technology means an emission-control technology 

that experiences a significant drop in emission-control performance or 

emission-system durability when an engine is operated on low-sulfur fuel 

(i.e., fuel with a sulfur concentration up to 500 ppm) as compared to 

when it is operated on ultra low-sulfur fuel (i.e., fuel with a sulfur 

concentration less than 15 ppm). Exhaust-gas recirculation is not a 

sulfur-sensitive technology.

    Test fleet means the engine or group of engines that a manufacturer 

uses during certification to determine compliance with emission 

standards.

    Tier 1 engine means an engine subject to the Tier 1 emission 

standards listed in Sec.  89.112(a).

    Tier 2 engine means an engine subject to the Tier 2 emission 

standards listed in Sec.  89.112(a).

    Tier 3 engine means an engine subject to the Tier 3 emission 

standards listed in Sec.  89.112(a).

    Ultimate purchaser means, with respect to any new nonroad engine, 

new nonroad vehicle, or new nonroad equipment, the first person who in 

good faith purchases such new nonroad engine, nonroad vehicle, or 

nonroad equipment for purposes other than resale.

    United States means the States, the District of Columbia, the 

Commonwealth of Puerto Rico, the Commonwealth of the Northern Mariana 

Islands, Guam, American Samoa, and the U.S. Virgin Islands.

    Used solely for competition means exhibiting features that are not 

easily removed and that would render its use other than in competition 

unsafe, impractical, or highly unlikely.

    U.S.-directed production volume means the number of nonroad 

equipment, vehicle, or marine diesel engine units produced by a 

manufacturer for which the manufacturer has reasonable assurance that 

sale was or will be made to ultimate purchasers in the United States.
