TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 1051_CONTROL OF EMISSIONS FROM RECREATIONAL ENGINES AND VEHICLES
--Table of Contents
Subpart B_Emission Standards and Related Requirements
Sec. 1051.135 How must I label and identify the vehicles I produce?
Each of your vehicles must have three labels: a vehicle
identification number as described in paragraph (a) of this section, an
emission control information label as described in paragraphs (b)
through (e) of this section, and a consumer information label as
described in paragraph (g) of this section.
(a) Assign each production vehicle a unique identification number
and permanently and legibly affix, stamp, or engrave it on the vehicle.
(b) At the time of manufacture, add a permanent label identifying
the emission controls for each vehicle. This is the vehicle's ``emission
control information label.'' To meet labeling requirements, do the
following things:
(1) Attach the label in one piece so it is not removable without
being destroyed or defaced.
(2) Design and produce it to be durable and readable for the
vehicle's entire life.
(3) Secure it to a part of the vehicle (or engine) needed for normal
operation and not normally requiring replacement.
(4) Write it in block letters in English.
(5) Attach the label in a location where it can be easily read.
(c) On your label, do these things:
(1) Include the heading ``EMISSION CONTROL INFORMATION''.
(2) Include your full corporate name and trademark.
(3) State: ``THIS VEHICLE IS CERTIFIED TO OPERATE ON [specify
operating fuel or fuels].''.
(4) Identify the emission-control system; your identifiers must use
names and abbreviations consistent with SAE J1930 (incorporated by
reference in Sec. 1051.810).
(5) List all requirements for fuel and lubricants.
(6) State the date of manufacture [DAY (optional), MONTH, and YEAR];
if you stamp it on the engine and print it in the owner's manual, you
may omit this information from the emission control information label.
(7) State: ``THIS VEHICLE MEETS U.S. ENVIRONMENTAL PROTECTION AGENCY
REGULATIONS FOR [MODEL YEAR] [SNOWMOBILES or OFF-ROAD MOTORCYCLES or
ATVs].''.
(8) Include EPA's standardized designation for the engine family.
(9) State the engine's displacement (in liters) and maximum brake
power. You do not need to include the engine's displacement and power on
the emission control information label if the vehicle is permanently
labeled with a unique model name that corresponds to a specific
displacement/power configuration.
(10) State the engine's useful life if it is different than the
minimum value.
(11) List specifications and adjustments for engine tuneups; show
the proper position for the transmission during tuneup and state which
accessories should be operating.
(12) Identify the emission standards or family emission limits to
which you have certified the engine.
[[Page 610]]
(d) Some of your engines may need more information on the emission
control information label. If you produce an engine or vehicle that we
exempt from the requirements of this part, see subpart G of this part
and 40 CFR part 1068, subparts C and D, for more label information.
(e) Some engines may not have enough space for an emission control
information label with all the required information. In this case, you
may omit the information required in paragraphs (c)(3), (c)(4), and
(c)(5) of this section if you print it in the owner's manual instead.
(f) If you are unable to meet these labeling requirements, you may
ask us to modify them consistent with the intent of this section.
(g) Label every vehicle certified under this part with a removable
hang-tag showing its emission characteristics relative to other models.
The label should be attached securely to the vehicle before it is
offered for sale in such a manner that it would not be accidentally
removed prior to sale. Use the applicable equations of this paragraph
(g) to determine the normalized emission rate (NER) from the FEL for
your vehicle. If the vehicle is certified without using the averaging
provisions of subpart H, use the final deteriorated emission level.
Round the resulting normalized emission rate for your vehicle to the
nearest whole number. We may specify a standardized format for labels.
At a minimum, the tag should include: The manufacturer's name, vehicle
model name, engine description (500 cc two-stroke with DFI), the NER,
and a brief explanation of the scale (for example, note that 0 is the
cleanest and 10 is the least clean).
(1) For snowmobiles, use the following equation:
NER = 16.61 x log(2.667 x HC + CO) - 38.22
Where:
HC and CO are the cycle-weighted FELs (or emission rates) for
hydrocarbons and carbon monoxide in g/kW-hr.
(2)(i) For off-highway motorcycles with HC+NOX emissions
less than or equal to 2.0 g/km, use the following equation:
(NER = 2.500 x (HC + NOX)
Where:
HC +NOX is the FEL (or the sum of the cycle-weighted emission
rates) for hydrocarbons and oxides of nitrogen in g/km.
(ii) For off-highway motorcycles with HC+NOX emissions
greater than 2.0 g/km, use the following equation:
NER = 5.000 x log(HC + NOX) + 3.495
Where:
HC +NOX is the FEL (or the sum of the cycle-weighted emission
rates) for hydrocarbons and oxides of nitrogen in g/km.
(3)(i) For ATVs with HC+NOX emissions less than or equal
to 1.5 g/km, use the following equation:
NER = 3.333 x (HC + NOX)
Where:
HC +NOX is the FEL (or the sum of the cycle-weighted emission
rates) for hydrocarbons and oxides of nitrogen in g/km.
(ii) For ATVs with HC+NOX emissions greater than 1.5 g/
km, use the following equation:
NER = 4.444 x log(HC + NOX) + 4.217
Where:
HC +NOX is the FEL (or the sum of the cycle-weighted emission
rates) for hydrocarbons and oxides of nitrogen in g/km.
