SPARK-IGNITION ENGINES--Table of Contents
 
                     Subpart G_Compliance Provisions
 
Sec.  1048.610  What provisions apply to vehicles certified under the motor-vehicle program?

    (a) General provisions. If you are a motor-vehicle manufacturer, 
this section allows you to introduce new nonroad engines or equipment 
into commerce if the vehicle is already certified to the requirements 
that apply under 40 CFR parts 85 and 86 for the appropriate model year. 
If you comply with all of the provisions of this section, we consider 
the certificate issued

[[Page 585]]

under 40 CFR part 86 for each motor vehicle to also be a valid 
certificate of conformity for the engine under this part 1048 for its 
model year, without a separate application for certification under the 
requirements of this part 1048. See Sec.  1048.605 or similar provisions 
that apply to motor-vehicle engines produced for nonroad equipment. The 
provisions of this section do not apply to engines certified to meet the 
requirements for highway motorcycles.
    (b) Equipment-manufacturer provisions. If you are not a motor-
vehicle manufacturer, you may produce nonroad equipment from motor 
vehicles under this section as long as you meet all the requirements and 
conditions specified in paragraph (d) of this section. If you modify the 
motor vehicle or its engine in any of the ways described in paragraph 
(d)(2) of this section, we will consider you a manufacturer of a new 
nonroad engine. Such modifications prevent you from using the provisions 
of this section.
    (c) Liability. Engines, vehicles, and equipment for which you meet 
the requirements of this section are exempt from all the requirements 
and prohibitions of this part, except for those specified in this 
section. Engines exempted under this section must meet all the 
applicable requirements from 40 CFR parts 85 and 86. This applies to 
engine manufacturers, equipment manufacturers, and all other persons as 
if the nonroad equipment were motor vehicles. The prohibited acts of 40 
CFR 1068.101(a)(1) apply to these new pieces of equipment; however, we 
consider the certificate issued under 40 CFR part 86 for each motor 
vehicle to also be a valid certificate of conformity for the engine 
under this part 1048 for its model year. If we make a determination that 
these engines, vehicles, or equipment do not conform to the regulations 
during their useful life, we may require you to recall them under 40 CFR 
part 86 or 40 CFR 1068.505.
    (d) Specific requirements. If you are a motor-vehicle manufacturer 
and meet all the following criteria and requirements regarding your new 
nonroad equipment and its engine, the engine is eligible for an 
exemption under this section:
    (1) Your equipment must be covered by a valid certificate of 
conformity as a motor vehicle issued under 40 CFR part 86.
    (2) You must not make any changes to the certified vehicle that we 
could reasonably expect to increase its exhaust emissions for any 
pollutant, or its evaporative emissions if it is subject to evaporative-
emission standards. For example, if you make any of the following 
changes, you do not qualify for this exemption:
    (i) Change any fuel system or evaporative system parameters from the 
certified configuration, including refueling emission controls.
    (ii) Change, remove, or fail to properly install any other 
component, element of design, or calibration specified in the vehicle 
manufacturer's application for certification. This includes 
aftertreatment devices and all related components.
    (iii) Modify or design the engine cooling system so that 
temperatures or heat rejection rates are outside the original vehicle 
manufacturer's specified ranges.
    (iv) Add more than 500 pounds to the curb weight of the originally 
certified motor vehicle.
    (3) You must show that fewer than 50 percent of the engine family's 
total sales in the United States are used in nonroad applications. This 
includes any type of vehicle, without regard to which company completes 
the manufacturing of the nonroad equipment. Show this as follows:
    (i) If you are the original manufacturer of the vehicle, base this 
showing on your sales information.
    (ii) In all other cases, you must get the original manufacturer of 
the vehicle to confirm this based on their sales information.
    (4) The equipment must have the vehicle emission control information 
and fuel labels we require under 40 CFR 86.007-35.
    (5) You must add a permanent supplemental label to the equipment in 
a position where it will remain clearly visible. In the supplemental 
label, do the following:
    (i) Include the heading: ``NONROAD ENGINE EMISSION CONTROL 
INFORMATION''.

[[Page 586]]

    (ii) Include your full corporate name and trademark. You may instead 
include the full corporate name and trademark of another company you 
choose to designate.
    (iii) State: ``THIS VEHICLE WAS ADAPTED FOR NONROAD USE WITHOUT 
AFFECTING ITS EMISSION CONTROLS. THE EMISSION-CONTROL SYSTEM DEPENDS ON 
THE USE OF FUEL MEETING SPECIFICATIONS THAT APPLY FOR MOTOR-VEHICLE 
APPLICATIONS. OPERATING THE ENGINE ON OTHER FUELS MAY BE A VIOLATION OF 
FEDERAL LAW.''.
    (iv) State the date you finished modifying the vehicle (month and 
year), if applicable.
    (6) The original and supplemental labels must be readily visible in 
the fully assembled equipment.
    (7) Send the Designated Compliance Officer a signed letter by the 
end of each calendar year (or less often if we tell you) with all the 
following information:
    (i) Identify your full corporate name, address, and telephone 
number.
    (ii) List the equipment models you expect to produce under this 
exemption in the coming year.
    (iii) State: ``We produced each listed engine or equipment model for 
nonroad application without making any changes that could increase its 
certified emission levels, as described in 40 CFR 1048.610.''.
    (e) Failure to comply. If your engines, vehicles, or equipment do 
not meet the criteria listed in paragraph (d) of this section, the 
engines will be subject to the standards, requirements, and prohibitions 
of this part 1048, and the certificate issued under 40 CFR part 86 will 
not be deemed to also be a certificate issued under this part 1048. 
Introducing these engines into commerce without a valid exemption or 
certificate of conformity under this part violates the prohibitions in 
40 CFR 1068.101(a)(1).
    (f) Data submission. We may require you to send us emission test 
data on any applicable nonroad duty cycles.
    (g) Participation in averaging, banking and trading. Vehicles 
adapted for nonroad use under this section may generate credits under 
the ABT provisions in 40 CFR part 86. These vehicles must use emission 
credits under 40 CFR part 86 if they are certified to an FEL that 
exceeds an applicable standard under 40 CFR part 86.
