40 CFR Part 1051
Exhaust Emission Test Procedures for All-Terrain Vehicles
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of proposed rulemaking.
SUMMARY: In a rule published November 8, 2002, EPA promulgated new
emission standards for recreational vehicles beginning in model year
2006. This included a newly regulated class of nonroad vehicles/engines
commonly referred to as all-terrain vehicles. In that rulemaking, a
temporary provision was included allowing manufacturers to certify all-
terrain vehicles over a steady-state, engine-based, duty cycle for
exhaust emissions prior to the 2009 model year in lieu of the
transient, chassis-based, Federal Test Procedure which was effective
for 2006 and later model years. In this rulemaking we are proposing to
extend the availability of this temporary provision for in some cases
up to an additional six model years, after which the chassis-based
Federal Test Procedure would become the only available test cycle. More
specifically, manufacturers would have to certify exhaust emission
engine families representing not less than 50 percent of their U.S.-
directed production on the Federal Test Procedure in model year 2014
and 100 percent in 2015. Manufacturers with only one all-terrain
vehicle exhaust emission engine engine family would not be required to
use the Federal Test Procedure until the 2015 model year. For those
manufacturers who have not yet done so, this will allow additional time
to certify to the previously promulgated Federal Test Procedure-based
emission standards using either contract facilities or by obtaining in-

I. General Information
In the ``Rules and Regulations'' section of this Federal Register,
we are making these revisions as a direct final rule without prior
proposal because we view these revisions as noncontroversial and
anticipate no adverse comment.
We have explained our reasons for these revisions in the preamble
to the direct final rule. If we receive no adverse comment, we will not
take further action on this proposed rule. If we receive adverse
comment on the rule, we will withdraw the direct final rule. We will
address all public comments in a subsequent final rule based on this
proposed rule. We will not institute a second comment period on this
action. Any parties interested in commenting must do so at this time.
II. Does This Action Apply to Me?
This action will affect companies that manufacture and certify all-
terrain vehicles in the United States.

IV. Summary of Rule
In a rule published November 8, 2002, EPA promulgated new emission
standards for all terrain vehicles (ATVs) beginning in model year 2006.
In that rulemaking, a temporary provision was included allowing
manufacturers to certify ATV exhaust emissions over a steady-state,
engine-based, duty cycle prior to the 2009 model year in lieu of the
transient, chassis-based, Federal Test Procedure (FTP) which was
effective for 2006 and later model years. In the interim the
manufacturers, the California Air Resources Board, and EPA were to work
together to assess the in-use operating characteristics of ATVs,
determine whether the nature of this operation was transient or steady
state and, if workable, develop and agree upon an emission test cycle
which could replace both the engine-based steady state option and the
primary approach, the chassis-based FTP. This work did not result in a
mutually satisfactory outcome and agreement could not be reached on an
alternate testing approach. Therefore, as prescribed in the 2002 final
rule, the chassis-based FTP is to be the sole procedure for exhaust
emissions certification in the long term.
As stated above, in the original rulemaking the steady state option
expired for the 2009 model year. While many manufacturers have
certified using the FTP not all have done so, since there was the
possibility of a replacement cycle. To provide appropriate certainty
and lead time, in this rulemaking we are proposing to extend the
availability of this temporary provision for an additional six model
years, after which the chassis-based FTP would become the only
available approach. More specifically, we are proposing that
manufacturers would have to certify exhaust emission engine families
representing not less than 50 percent of their U.S.-directed production
on the FTP in model year 2014 and 100 percent in 2015. Manufacturers
with only one ATV exhaust emission engine family would not be required
to use the FTP until the 2015 model year. For those manufacturers who
have not yet done so, this will allow additional time to certify on the
FTP by using contract facilities or by obtaining the in-house
capability and if a large manufacturer acquires the capability to run
the production line testing program.
EPA does not expect that this revision will have any adverse cost
impact to the manufacturers in the long term. The requirement was
promulgated as part of the 2002 final rule and many off-shore
manufacturers and importers have already complied using excess inhouse
capability or contract facilities. We expect this extension will help
to ensure compliance costs are minimized and that the emission
reductions identified in the 2002 rule are achieved. Even the J1088
test cycle has reduced emissions significantly by eliminating ATVs
powered by high emitting two-stroke engines as a new product offering.
Adopting the FTP will help to ensure robust emission control in ATVs
using 4-stroke engines by including consideration of transient
operation and vehicle/engine operation over a wider variety of
conditions than that seen in the J1088 cycle.
For additional discussion of the proposed rule changes, see the
direct final rule EPA has published in the ``Rules and Regulations''
section of today's Federal Register. This proposal incorporates by
reference all the reasoning, explanation, and regulatory text from the
direct final rule.
