TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 86--CONTROL OF EMISSIONS FROM NEW AND IN-USE HIGHWAY VEHICLES AND ENGINES--Table of Contents
Subpart A--General Provisions for Emission Regulations for 1977 and
Sec. 86.000-8 Emission standards for 2000 and later model year light-duty vehicles.
Section 86.000-8 includes text that specifies requirements that
differ from Sec. 86.096-8 or Sec. 86.099-8. Where a paragraph in
Sec. 86.096-8 or Sec. 86.099-8 is identical and applicable to
Sec. 86.000-8, this may be indicated by specifying the corresponding
paragraph and the statement ``[Reserved]. For guidance see Sec. 86.096-
8.'' or ``[Reserved]. For guidance see Sec. 86.099-8.''

(e) SFTP Standards. (1) Exhaust emissions from 2000 and later model
year light-duty vehicles shall meet the additional SFTP standards of
table A00-2 (defined by useful life, fuel type, and test type) according
to the implementation schedule in table A00-1. The standards set forth
in table A00-2 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. 86.096-8 (a)(1)
introductory text through (a)(1)(ii)(B) and 86.099-8 (a)(1)(iii) through
(a)(3):

(i) A minimum of the percentage shown in table A00-1 of a
manufacturer's sales of the applicable model year's light-duty vehicles
shall not exceed the applicable SFTP standards in table A00-2 when
tested under the procedures in subpart B of this part indicated for 2000
and later model year light-duty vehicles.
(ii) Optionally, a minimum of the percentage shown in table A00-1 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, and the
[[Page 16]]
light light-duty trucks shall not exceed the applicable SFTP standards
in table A00-4 of Sec. 86.000-9.
(iii) Sales percentages for the purposes of determining compliance
with this paragraph (e)(1) shall be based on total actual U.S. sales of
light-duty vehicles 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 paragraph (e)(1)(ii)
of this section 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.
(iv) 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 A00-1. 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.
(2) These SFTP standards do not apply to vehicles certified on
alternative fuels, but the standards do apply to the gasoline and diesel
fuel operation of flexible fuel vehicles and dual fuel vehicles.
(3) These SFTP standards do not apply to vehicles tested at high
altitude.
(4) 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.
(5) 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 families which
are designated as SFTP compliant under the implementation schedule in
table A00-1.
(6) 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).
(7) 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 families will be used to attain the required
implementation schedule sales percentages for certification purposes.
(8) 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 families which are used to meet the
intermediate useful life standards will be required without deviation to
meet the corresponding full useful life standards.
(9) Compliance with composite standards shall be demonstrated using
the calculations set forth in Sec. 86.164-00.
(f) [Reserved]
(g) through (k) [Reserved]. For guidance see Sec. 86.096-8.
