(e) SFTP Standards. (1) Light light-duty trucks. (i) Exhaust
emissions from 2000 and later model year light light-duty trucks shall
meet the additional SFTP standards of table A00-4 (defined by useful
life, fuel type, truck type, loaded vehicle weight (LVW), and test type)
according to the implementation schedule in table A00-3. The standards
set forth in table A00-4 refer to exhaust emissions emitted over the
Supplemental Federal Test Procedure (SFTP) as set forth in subpart B of
this part and collected and calculated in accordance with those
procedures. Compliance with these standards are an additional
requirement to the required compliance with Tier 1 standards as defined

(A) A minimum of the percentage shown in table A00-3 of a
manufacturer's sales of the applicable model year's light light-duty
trucks shall not exceed the applicable SFTP standards in table A00-4
when tested under the procedures in subpart B of this part indicated for
2000 and later model year light light-duty trucks.
(B) Optionally, a minimum of the percentage shown in table A00-3 of
a manufacturer's combined sales of the applicable model year's light-
duty vehicles and light light-duty trucks shall not exceed the
applicable SFTP standards. Under this option, the light-duty vehicles
shall not exceed the applicable SFTP standards in table A00-2 of
Sec. 86.000-8, and the light light-duty trucks shall not exceed the
applicable SFTP standards in table A00-4.
(C) Sales percentages for the purposes of determining compliance
with paragraph (e)(1)(i)(A) of this section shall be based on total
actual U.S. sales of light light-duty trucks of the applicable model
year by a manufacturer to a dealer, distributor, fleet operator, broker,
or any other entity which comprises the point of first sale. If the
option of Sec. 86.097-9(a)(1)(i)(B) is taken, such sales percentages
shall be based on the total actual combined U.S. sales of light-duty
vehicles and light light-duty trucks of the applicable model year by a
manufacturer to a dealer, distributor, fleet operator, broker, or any
other entity which comprises the point of first sale.
(D) The manufacturer may petition the Administrator to allow actual
volume produced for U.S. sale to be used in lieu of actual U.S. sales
for purposes of determining compliance with the implementation schedule
sales percentages of table A000-3. Such petition shall be submitted
within 30 days of the end of the model year to the Vehicle Programs and
Compliance Division. For the petition to be granted, the manufacturer
must establish to the satisfaction of the Administrator that actual
production volume is functionally equivalent to actual sales volume.
[[Page 18]]
(ii) These SFTP standards do not apply to light light-duty trucks
certified on alternative fuels, but the standards do apply to the
gasoline and diesel fuel operation of flexible fuel vehicles and dual
fuel vehicles.
(iii) These SFTP standards do not apply to light light-duty trucks
tested at high altitude.
(iv) The air to fuel ratio shall not be richer at any time than the
leanest air to fuel mixture required to obtain maximum torque (lean best
torque), plus a tolerance of six (6) percent. The Administrator may
approve a manufacturer's request for additional enrichment if it can be
shown that additional enrichment is needed to protect the engine or
emissions control hardware.
(v) The requirement to use a single roll dynamometer (or a
dynamometer which produces equivalent results), discussed in
Secs. 86.108-00, 86.118-00, and 86.129-00, applies to all SFTP and FTP
test elements as set forth in subpart B of this part for engine families
which are designated as SFTP compliant under the implementation schedule
in table A00-3.
(vi) Small volume manufacturers, as defined in Sec. 86.094-14(b) (1)
and (2), are exempt from the requirements of this paragraph (e) until
model year 2002, when 100 percent compliance with the standards of this
paragraph (e) is required. This exemption does not apply to small volume
engine families as defined in Sec. 86.094-14(b)(5).
(vii) The manufacturer must state at the time of Application for
Certification, based on projected U.S. sales or projected production for
U.S. sale, which engine families will be used to attain the required
implementation schedule sales percentages for certification purposes.
(viii) A manufacturer cannot use one set of engine families to meet
its intermediate useful life standards and another to meet its full
useful life standards. The same engine families which are used to meet
the intermediate useful life standards will be required without
deviation to meet the corresponding full useful life standards.
(ix) Compliance with composite standards shall be demonstrated using
the calculations set forth in Sec. 86.164-00.
(2) Heavy light-duty trucks. (i) Exhaust emissions from 2002 and
later model year heavy light-duty trucks shall meet the SFTP standards
of table A00-6 (defined by useful life, fuel type, truck type, adjusted
loaded vehicle weight (ALVW), and test type) according to the
implementation schedule in table A00-5. The standards set forth in table
A00-6 refer to exhaust emissions emitted over the Supplemental Federal
Test Procedure (SFTP) as set forth in subpart B of this part and
collected and calculated in accordance with those procedures. Compliance
with these standards are an additional requirement to the required
compliance with Tier 1 standards as defined in Secs. 86.097-9(a)(1)
introductory text through (a)(1)(iii) and 86.099-9(a)(1)(iv) through
(a)(3):
