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 Later
Sec. 86.004-21 Application for certification.
Section 86.004-21 includes text that specifies requirements that
differ from Sec. 86.094-21 or Sec. 86.096-21. Where a paragraph in
Sec. 86.094-21 or Sec. 86.096-21 is identical and applicable to Sec.
86.004-21, this may be indicated by specifying the corresponding
paragraph and the statement ``[Reserved]. For guidance see Sec. 86.094-
21.'' or ``[Reserved]. For guidance see Sec. 86.096-21.''.
(a)-(b)(3) [Reserved]. For guidance see Sec. 86.094-21.
(b)(4)(i) For light-duty vehicles and light-duty trucks, a
description of the test procedures to be used to establish the
evaporative emission and/or refueling emission deterioration factors, as
appropriate, required to be determined and supplied in Sec. 86.001-
23(b)(2).
(b)(4)(ii)-(b)(5)(iv) [Reserved]. For guidance see Sec. 86.094-21.
(b)(5)(v) For light-duty vehicles and applicable light-duty trucks
with non-integrated refueling emission control systems, the number of
continuous UDDS cycles, determined from the fuel economy on the UDDS
applicable to the test vehicle of that evaporative/ refueling emission
family-emission control system combination, required to use a volume of
fuel equal to 85% of fuel tank volume.
(6) Participation in averaging programs--(i) Particulate averaging.
(A) If the manufacturer elects to participate in the particulate
averaging program for diesel light-duty vehicles and/or diesel light-
duty trucks or the particulate averaging program for heavy-duty diesel
engines, the application must list the family particulate emission limit
and the projected U.S. production volume of the family for the model
year.
(B) The manufacturer shall choose the level of the family
particulate emission limits, accurate to hundredth of a gram per mile or
hundredth of a gram per brake horsepowerhour for HDEs.
(C) The manufacturer may at any time during production elect to
change the level of any family particulate emission limit(s) by
submitting the new limit(s) to the Administrator and by demonstrating
compliance with the limit(s) as described in Sec. Sec. 86.090-2 and
86.094-28(b)(5)(i).
(ii) NOX and NOX plus NMHC averaging. (A) If the manufacturer elects
to participate in the NOX averaging program for light-duty
trucks or otto-cycle HDEs or the NOX plus NMHC averaging
program for diesel-cycle HDEs, the application must list the
[[Page 48]]
family emission limit and the projected U.S. production volume of the
family for the model year.
(B) The manufacturer shall choose the level of the family emission
limits, accurate to one-tenth of a gram per mile or to one-tenth of a
gram per brake horsepower-hour for HDEs.
(C) The manufacturer may at any time during production elect to
change the level of any family emission limit(s) by submitting the new
limits to the Administrator and by demonstrating compliance with the
limit(s) as described in Sec. Sec. 86.088-2 and 86.094-28(b)(5)(ii).
(b)(7) and (b)(8) [Reserved]. For guidance see Sec. 86.094-21.
(b)(9) For each light-duty vehicle, light-duty truck, evaporative/
refueling emission family or heavy-duty vehicle evaporative emission
family, a description of any unique procedures required to perform
evaporative and/or refueling emission tests, as applicable, (including
canister working capacity, canister bed volume, and fuel temperature
profile for the running loss test) for all vehicles in that evaporative
and/or evaporative/refueling emission family, and a description of the
method used to develop those unique procedures.
(10) For each light-duty vehicle or applicable light-duty truck
evaporative/refueling emission family, or each heavy-duty vehicle
evaporative emission family:
(i) Canister working capacity, according to the procedures specified
in Sec. 86.132-96(h)(1)(iv);
(ii) Canister bed volume; and
(iii) Fuel temperature profile for the running loss test, according
to the procedures specified in Sec. 86.129-94(d).
(c)-(j) [Reserved]. For guidance see Sec. 86.094-21.
(k) and (l) [Reserved]. For guidance see Sec. 86.096-21.
(m) For model years 2004 through 2007, within 180 days after
submission of the application for certification of a heavy-duty diesel
engine, the manufacturer must provide emission test results from the
Load Response Test conducted according to Sec. 86.1380-2004, including,
at a minimum, test results conducted at each of the speeds identified in
Sec. 86.1380-2004. Load Response Test data submissions are not
necessary for carry-over engine families for which Load Response Test
data has been previously submitted. In addition, upon approval of the
Administrator, manufacturers may carry Load Response Test data across
from one engine family to other engine families, provided that the
carry-across engine families use similar emission control technology
hardware which would be expected to result in the generation of similar
emission data when run over the Load Response Test.
(n) Upon request from EPA, a manufacturer must provide to EPA any
hardware (including scan tools), passwords, and/or documentation
necessary for EPA to read, interpret, and store (in engineering units if
applicable) any information broadcast by an engine's on-board computers
and electronic control modules which relates in any way to emission
control devices and auxiliary emission control devices, provided that
such hardware, passwords, or documentation exists and is not otherwise
commercially available. Passwords include any information necessary to
enable generic scan tools or personal computers access to proprietary
emission related information broadcast by an engine's on-board computer,
if such passwords exist. This requirement includes access by EPA to any
proprietary code information which may be broadcast by an engine's on-
board computer and electronic control modules. Information which is
confidential business information must be marked as such. Engineering
units refers to the ability to read, interpret, and store information in
commonly understood engineering units, for example, engine speed in
revolutions per minute or per second, injection timing parameters such
as start of injection in degree's before top-dead center, fueling rates
in cubic centimeters per stroke, vehicle speed in miles per hour or
kilometers per hour. This paragraph (n) does not restrict EPA authority
to take any action authorized by section 208 of the Clean Air Act.
