PART 1051_CONTROL OF EMISSIONS FROM RECREATIONAL ENGINES
AND VEHICLES--Table of Contents
 
                     Subpart G_Compliance Provisions
 
Sec.  1051.605  What provisions apply to engines already certified under the
motor-vehicle program or the Large Spark-ignition program?

    (a) General provisions. If you are an engine manufacturer, this 
section allows you to introduce into commerce new recreational vehicles, 
and engines for recreational vehicles, if the engines are already 
certified to the requirements that apply to spark-ignition engines under 
40 CFR parts 85 and 86 or 40 CFR part 1048 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 or 1048 for each engine to 
also be a valid certificate of conformity under this part 1051 for its 
model year, without a separate application for certification under the 
requirements of this part 1051. See Sec.  1051.610 for similar 
provisions that apply to vehicles that are already certified to the 
vehicle-based standards for motor vehicles.
    (b) Vehicle-manufacturer provisions. If you are not an engine 
manufacturer, you may install an engine certified for the appropriate 
model year under 40 CFR part 86 or 1048 in a recreational vehicle as 
long as you meet all the requirements and conditions specified in 
paragraph (d) of this section. If you modify the non-recreational engine 
in any of the ways described in paragraph (d)(2) of this section for 
installation in a recreational vehicle, we will consider you a 
manufacturer of recreational vehicles. 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 or 40 CFR part 1048. This paragraph (c) applies to engine 
manufacturers, vehicle manufacturers who use such an engine, and all 
other persons as if the engine were used in its originally intended 
application. The prohibited acts of 40 CFR 1068.101(a)(1) apply to these 
new engines and vehicles; however, we consider the certificate issued 
under 40 CFR part 86 or 1048 for each engine to also be a valid 
certificate of conformity under this part 1051 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 this part 1051 or under 40 CFR part 85 or 1068.505.
    (d) Specific requirements. If you are an engine or vehicle 
manufacturer and meet all the following criteria and requirements 
regarding your new engine or vehicle, the vehicle using 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 or 1048.
    (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).

[[Page 654]]

    (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 recreational vehicles. 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 emission control 
information label we require under 40 CFR part 86 or 1048.
    (5) You must add a permanent supplemental label to the engine in a 
position where it will remain clearly visible after installation in the 
vehicle. In the supplemental label, do the following:
    (i) Include the heading: ``RECREATIONAL VEHICLE 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 A RECREATIONAL USE 
WITHOUT AFFECTING ITS EMISSION CONTROLS.''.
    (iv) State the date you finished installation (month and year), if 
applicable.
    (6) The original and supplemental labels must be readily visible 
after the engine is installed in the vehicle or, if the vehicle obscures 
the engine's emission control information label, the make sure the 
vehicle manufacturer attaches 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 vehicle models you expect to produce under 
this exemption in the coming year.
    (iii) State: ``We produce each listed [engine or vehicle] model for 
recreational application without making any changes that could increase 
its certified emission levels, as described in 40 CFR 1051.605.''.
    (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 1051 and the 
certificate issued under 40 CFR part 86 or 1048 will not be deemed to 
also be a certificate issued under this part 1051. 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 or 
vehicles adapted for recreational use under this section may not 
generate or use emission credits under this part 1051. These engines or 
vehicles may generate credits under the ABT provisions in 40 CFR part 
86. These engines or vehicles must use emission credits under 40 CFR 
part 86 if they are certified to an FEL that exceeds an applicable 
standard.
