                     Subpart G_Compliance Provisions
 
Sec. 1051.610  What are the provisions for producing recreational vehicles 

with engines already certified under the motor-vehicle program or the Large 
SI program?

    (a) You may produce a recreational vehicle without certifying it 
under this part by using a certified motor vehicle engine, or Large SI 
engine. This section does not apply if you manufacture the engine 
yourself; see Sec. 1051.605. In order to produce recreational vehicles 
under this section, you must meet all of the following criteria:
    (1) The engine or vehicle is certified to 40 CFR part 86 or part 
1048.
    (2) The engine is not adjusted outside the certifying manufacturer's 
specifications (see Sec. 1051.605(c)(2)).
    (3) The engine or vehicle is not modified in any way that may affect 
its emission control. This does not apply to refueling emission 
controls.
    (4) The vehicle is labeled consistent with paragraph (c) of this 
section.
    (b)(1) The only requirements or prohibitions from this part that 
apply to a vehicle that is exempt under this section are in this section 
and Sec. 1051.605.
    (2) If the vehicles do not meet the criteria listed in Sec. 
1051.605(c) and paragraph (c) of this section, they will be subject to 
the standards and prohibitions of this part. Producing these vehicles 
without a valid exemption or certificate of conformity would violate the 
prohibitions in Sec. 1068.101 of this chapter.
    (3) Vehicles exempted under this section are subject to all the 
requirements affecting engines and vehicles under 40 CFR part 86 or part 
1048, as applicable. The requirements and restrictions of 40 CFR part 86 
or 1048 apply to anyone manufacturing these engines, anyone 
manufacturing vehicles that use these engines, and all other persons in 
the same manner as if these engines were used in a motor vehicle or 
other nonrecreational application.

    (c)(1) Make sure the original emission control information label is 
intact after assembly in the vehicle.
    (2) Add a permanent supplemental label to the vehicle in a position 
where it will be clearly visible. In this emission control information 
label, do the following:
    (i) Include the heading: ``Recreational Vehicle Emission Control 
Information''.
    (ii) Include your full corporate name and trademark.
    (iii) State: ``THIS ENGINE WAS ADAPTED FOR RECREATIONAL USE WITHOUT 
AFFECTING ITS EMISSION CONTROLS.''.
    (iv) State the date you finished installation (month and year).
    (3) Send the Designated 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 models you expect to produce under this exemption in 
the coming year.
    (iii) State: ``We produce each listed model for recreational 
application without making any changes that could increase its certified 
emission levels, as described in 40 CFR 1051.605.''.
    (d) If you build recreational vehicles under this section, we may 
require (as a condition of the exemption) that you comply with the 
emission-related warranty and recall responsibilities of this part.
    (e) If you build a recreational vehicle using a motor vehicle engine 
that was certified as part of a vehicle-based engine family, we may 
require you to certify under this part instead of granting you an 
exemption under this part. If we do this, we may allow you to submit an 
abbreviated application for certification to show that you comply with 
the requirements of this part. You may reference the information in the 
original motor vehicle application.
