PART 1048_CONTROL OF EMISSIONS FROM NEW, LARGE NONROAD 
SPARK-IGNITION ENGINES--Table of Contents
 
                     Subpart G_Compliance Provisions
 
Sec.  1048.605  What provisions apply to engines certified under
the motor-vehicle program?

    (a) General provisions. If you are an engine manufacturer, this 
section allows you to introduce new nonroad engines into commerce if 
they are already certified to the requirements that apply to engines 
under 40 CFR parts 85 and 86 for the appropriate model year. If you 
comply with all the provisions of this section, we consider the 
certificate issued under 40 CFR part 86 for each engine to also be a 
valid certificate of conformity under this part 1048 for its model year, 
without a separate application for certification under the requirements 
of this part 1048. See Sec.  1048.610 for similar provisions that apply 
to engines certified to chassis-based standards for motor vehicles.
    (b) Equipment-manufacturer provisions. If you are not an engine 
manufacturer, you may produce nonroad equipment using motor-vehicle 
engines 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 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 engine modifications prevent you from using the provisions 
of this section.
    (c) Liability. Engines 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 
who use these engines, and all other persons as if these engines were 
used in a motor vehicle. The prohibited acts of 40 CFR 1068.101(a)(1) 
apply to these new engines and equipment; however, we consider the 
certificate issued under 40 CFR part 86 for each engine to also be a 
valid certificate of conformity under this part 1048 for its model year. 
If we make a determination that these engines 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 an engine manufacturer or 
equipment manufacturer and meet all the following criteria and 
requirements regarding your new nonroad engine, the engine is eligible 
for an exemption under this section:
    (1) Your engine must be covered by a valid certificate of conformity 
issued under 40 CFR part 86.
    (2) You must not make any changes to the certified engine that could 
reasonably be expected to increase its exhaust emissions for any 
pollutant, or its evaporative emissions. For example, if you make any of 
the following changes to one of these engines, you do not qualify for 
this exemption:
    (i) Change any fuel system or evaporative system parameters from the 
certified configuration (this does not apply to refueling controls).
    (ii) Change, remove, or fail to properly install any other 
component, element of design, or calibration specified in the engine 
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 engine 
manufacturer's specified ranges.
    (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 engines used in any application without regard to which company 
manufactures the vehicle or equipment. Show this as follows:
    (i) If you are the original manufacturer of the engine, base this 
showing on your sales information.
    (ii) In all other cases, you must get the original manufacturer of 
the engine to confirm this based on its sales information.
    (4) You must ensure that the engine has the label we require under 
40 CFR part 86.
    (5) You must add a permanent supplemental label to the engine in a 
position where it will remain clearly visible after installation in the 
equipment. In the supplemental label, do the following:
    (i) Include the heading: ``NONROAD ENGINE EMISSION CONTROL 
INFORMATION''.
    (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 ENGINE 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 engine (month and 
year), if applicable.
    (6) The original and supplemental labels must be readily visible 
after the engine is installed in the equipment or, if the equipment 
obscures the engine's emission control information label, the equipment 
manufacturer must attach duplicate labels, as described in 40 CFR 
1068.105.
    (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 engine or equipment models you expect to produce under 
this exemption in the coming year.
    (iii) State: ``We produce 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 1048.605.''.
    (e) Failure to comply. If your engines do not meet the criteria 
listed in paragraph (d) of this section, they 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. Engines adapted 
for nonroad use under this section may generate credits under the ABT 
provisions in 40 CFR part 86. These engines 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.
