PART 85--CONTROL OF AIR POLLUTION FROM MOBILE SOURCES

    10. The authority citation for part 85 continues to read as follows:

    Authority: 42 U.S.C. 7401-7671q.

Subpart P--[Amended]

    11. Section 85.1515 is amended by adding paragraphs (c)(2)(vii), 
(c)(2)(viii), and (c)(8) to read as follows.

Sec.  85.1515  Emission standards and test procedures applicable to 
imported nonconforming motor vehicles and motor vehicle engines.

* * * * *
    (c) * * *
    (2) * * *
    (vii) Nonconforming LDV/LLDTs originally manufactured in OP years 
2009 and later must meet the evaporative emission standards in Table 
S09-1 in 40 CFR 86.1811-09(e). However, LDV/LLDTs originally 
manufactured in OP years 2009 and 2010 and imported by ICIs who qualify 
as small volume manufacturers as defined in 40 CFR 86.1838-01 are 
exempt from the LDV/LLDT evaporative emission standards in Table S09-1 
in 40 CFR 86.1811-09(e), but must comply with the Tier 2 evaporative 
emission standards in Table S04-3 in 40 CFR 86.1811-04(e).
    (viii) Nonconforming HLDTs and MDPVs originally manufactured in OP 
years 2010 and later must meet the evaporative emission standards in 
Table S09-1 in 40 CFR 86.1811-09(e). However, HLDTs and MDPVs 
originally manufactured in OP years 2010 and 2011 and imported by ICIs, 
who qualify as small volume manufacturers as defined in 40 CFR 86.1838-
01, are exempt from the HLDTs and MDPVs evaporative emission standards 
in Table S09-1 in 40 CFR 86.1811-09(e), but must comply with the Tier 2 
evaporative emission standards in Table S04-3 in 40 CFR 86.1811-04(e).
* * * * *
    (8)(i) Nonconforming LDV/LLDTs originally manufactured in OP years 
2010 and later must meet the cold temperature NHMC emission standards 
in Table S10-1 in 40 CFR 86.1811-10(g).
    (ii) Nonconforming HLDTs and MDPVs originally manufactured in OP 
years 2012 and later must meet the cold temperature NHMC emission 
standards in Table S10-1 in 40 CFR 86.1811-10(g).
    (iii) ICIs, which qualify as small volume manufacturers, are exempt 
from the cold temperature NMHC phase-in intermediate percentage 
requirements described in 40 CFR 86.1811-10(g)(3). See 40 CFR 86.1811-
04(k)(5)(vi) and (vii).
    (iv) As an alternative to the requirements of paragraphs (c)(8)(i) 
and (ii) of this section, ICIs may elect to meet a cold temperature 
NMHC family emission level below the cold temperature NMHC fleet 
average standards specified in Table S10-1 of 40 CFR 86.1811-10 and 
bank or sell credits as permitted in 40 CFR 86.1864-10. An ICI may not 
meet a higher cold temperature NMHC family emission level than the 
fleet average standards in Table S10-1 of 40 CFR 86.1811-10 as 
specified in paragraphs (c)(8)(i) and (ii) of this section, unless it 
demonstrates to the Administrator at the time of certification that it 
has obtained appropriate and sufficient NMHC credits from another 
manufacturer, or has generated them in a previous model year or in the 
current model year and not traded them to another manufacturer or used 
them to address other vehicles as permitted in 40 CFR 86.1864-10.
    (v) Where an ICI desires to obtain a certificate of conformity 
using a higher cold temperature NMHC family emission level than 
specified in paragraphs (c)(8)(i) and (ii) of this section, but does 
not have sufficient credits to cover vehicles imported under such 
certificate, the Administrator may issue such certificate if the ICI 
has also obtained a certificate of conformity for vehicles certified 
using a cold temperature NMHC family emission level lower than that 
required under paragraphs (c)(8)(i) and (ii) of this section. The ICI 
may then import vehicles to the higher cold temperature NMHC family 
emission level only to the extent that it has generated sufficient 
credits from vehicles certified to a family emission level lower than 
the cold temperature NMHC fleet average standard during the same model 
year.
    (vi) ICIs using cold temperature NMHC family emission levels higher 
than the cold temperature NMHC fleet average standards specified in 
paragraphs (c)(8)(i) and (ii) of this section must monitor their 
imports so that they do not import more vehicles certified to such 
family emission levels than their available credits can cover. ICIs 
must not have a credit deficit at the end of a model year and are not 
permitted to use the deficit carryforward provisions provided in 40 CFR 
86.1864-10.
    (vii) The Administrator may condition the certificates of 
conformity issued to ICIs as necessary to ensure that vehicles subject 
to this paragraph (c)(8) comply with the applicable cold temperature 
NMHC fleet average standard for each model year.

PART 86--CONTROL OF EMISSIONS FROM NEW AND IN-USE HIGHWAY VEHICLES 
AND ENGINES

    12. The authority citation for part 86 continues to read as follows:

    Authority: 42 U.S.C. 7401-7671q.

Subpart H--[Amended]

    13. Section 86.701-94 is amended by revising paragraph (a) to read 
as follows:

Sec.  86.701-94  General applicability.

    (a) The provisions of this subpart apply to: 1994 through 2003 
model year Otto-cycle and diesel light-duty vehicles; 1994 through 2003 
model year Otto-cycle and diesel light-duty trucks; and 1994 and later 
model year Otto-cycle and diesel heavy-duty engines; and 2001 and later 
model year Otto-cycle heavy-duty vehicles and engines certified under 
the provisions of subpart S of this part. The provisions of subpart B 
of this part apply to this subpart. The provisions of Sec.  86.1811-
04(a)(5) and (p) apply to 2004 and later model year light-duty 
vehicles, light-duty trucks, and medium duty passenger vehicles.
* * * * *

Subpart S--[Amended]

    14. Section 86.1803-01 is amended by revising the definition of 
``Banking'' and adding the definition for ``Fleet average cold 
temperature NMHC standard'' to read as follows:

Sec.  86.1803-01  Definitions.

* * * * *
    Banking means one of the following:
    (1) The retention of NOX emission credits for complete 
heavy-duty vehicles by the manufacturer generating the emission 
credits, for use in future model year certification programs as 
permitted by regulation.

[[Page 15954]]

    (2) The retention of cold temperature non-methane hydrocarbon 
(NMHC) emission credits for light-duty vehicles, light-duty trucks, and 
medium-duty passenger vehicles by the manufacturer generating the 
emission credits, for use in future model year certification programs 
as permitted by regulation.
* * * * *
    Fleet average cold temperature NMHC standard means, for light-duty 
vehicles, light-duty trucks and medium-duty passenger vehicles, an NMHC 
cold temperature standard imposed over an individual manufacturer's 
total 50-State U.S. sales (or a fraction of total U.S. sales during 
phase-in years), as ``U.S. sales'' is defined to include all national 
sales, including points-of-first sale in California, of a given model 
year. Manufacturers determine their compliance with such a standard by 
averaging, on a sales-weighted basis, the individual NMHC ``Family 
Emission Limits'' (FEL--as defined in this subpart) to which light-duty 
vehicles, light-duty trucks and medium-duty passenger vehicles were 
certified and sold for that model year.
* * * * *
    15. Section 86.1805-04 is amended by adding paragraph (g) to read 
as follows:

Sec.  86.1805-04  Useful life.

* * * * *
    (g) Where cold temperature NMHC standards are applicable, the 
useful life requirement for compliance with the cold temperature NMHC 
standard only is as follows:
    (1) For LDV/LLDTs, 10 years or 120,000 miles, whichever occurs first.
    (2) For HLDT/MDPVs, 11 years or 120,000 miles, whichever occurs first.
    16. A new Sec.  86.1809-10 is added to Subpart S to read as follows:

Sec.  86.1809-10  Prohibition of defeat devices.

    (a) No new light-duty vehicle, light-duty truck, medium-duty 
passenger vehicle, or complete heavy-duty vehicle shall be equipped 
with a defeat device.
    (b) The Administrator may test or require testing on any vehicle at 
a designated location, using driving cycles and conditions which may 
reasonably be expected to be encountered in normal operation and use, 
for the purposes of investigating a potential defeat device.
    (c) For cold temperature CO and cold temperature NMHC emission 
control, the Administrator will use a guideline to determine the 
appropriateness of the CO and NMHC emission control at ambient 
temperatures between 25 [deg]F (4 [deg]C) (the upper bound of the cold 
test range) and 68 [deg]F (20 [deg]C) (the lower bound of the FTP 
range). The guideline for CO emission congruity across the intermediate 
temperature range is the linear interpolation between the CO standard 
applicable at 25 [deg]F (4 [deg]C) and the CO standard applicable at 68 
[deg]F (20 [deg]C). The guideline for NMHC emission congruity across 
the intermediate temperature range is the linear interpolation between 
the NMHC FEL applicable at 25 [deg]F (4 [deg]C) and the Tier 2 NMOG 
standard to which the vehicle was certified at 68 [deg]F (20 [deg]C), 
where the intermediate temperature NMHC level is rounded to the nearest 
hundredth for comparison to the interpolated line. For vehicles that 
exceed this CO emissions guideline or this NMHC emissions guideline 
upon intermediate temperature cold testing:
    (1) If the CO emission level is greater than the 20 [deg]F (7 
[deg]C) emission standard, the vehicle will automatically be considered 
to be equipped with a defeat device without further investigation. If 
the intermediate temperature NMHC emission level, rounded to the 
nearest hundredth, is greater than the 20 [deg]F (7 [deg]C) FEL, the 
vehicle will automatically be considered to be equipped with a defeat 
device without further investigation.
    (2) If the CO emission level does not exceed the 20 [deg]F emission 
standard, the Administrator may investigate the vehicle design for the 
presence of a defeat device under paragraph (d) of this section. If the 
intermediate temperature NMHC emission level, rounded to the nearest 
hundredth, does not exceed the 20 [deg]F FEL, the Administrator may 
investigate the vehicle design for the presence of a defeat device 
under paragraph (d) of this section.
    (d) For vehicle designs designated by the Administrator to be 
investigated for possible defeat devices:
    (1) The manufacturer must show to the satisfaction of the 
Administrator that the vehicle design does not incorporate strategies 
that unnecessarily reduce emission control effectiveness exhibited 
during the Federal or Supplemental Federal emissions test procedures 
(FTP or SFTP) when the vehicle is operated under conditions which may 
reasonably be expected to be encountered in normal operation and use.
    (2) The following information requirements apply:
    (i) Upon request by the Administrator, the manufacturer will 
provide an explanation containing detailed information regarding test 
programs, engineering evaluations, design specifications, calibrations, 
on-board computer algorithms, and design strategies incorporated for 
operation both during and outside of the Federal emission test procedure.
    (ii) For purposes of investigations of possible cold temperature CO 
or cold temperature NMHC defeat devices under this paragraph (d), the 
manufacturer shall provide an explanation which must show, to the 
satisfaction of the Administrator, that CO emissions and NMHC emissions 
are reasonably controlled in reference to the linear guideline across 
the intermediate temperature range.
    (e) For each test group of Tier 2 LDV/LLDTs and HLDT/MDPVs and 
interim non-Tier 2 LDV/LLDTs and HLDT/MDPVs the manufacturer must 
submit, with the Part II certification application, an engineering 
evaluation demonstrating to the satisfaction of the Administrator that 
a discontinuity in emissions of non-methane organic gases, carbon 
monoxide, oxides of nitrogen and formaldehyde measured on the Federal 
Test Procedure (subpart B of this part) does not occur in the 
temperature range of 20 to 86 degrees F. For diesel vehicles, the 
engineering evaluation must also include particulate emissions.
    17. A new Sec.  86.1810-09 is added to Subpart S to read as follows:

Sec.  86.1810-09  General standards; increase in emissions; unsafe 
condition; waivers.

    Section 86.1810-09 includes text that specifies requirements that 
differ from Sec.  86.1810-01. Where a paragraph in Sec.  86.1810-01 is 
identical and applicable to Sec.  86.1810-09, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.  86.1810-01.'' Where a corresponding paragraph of 
Sec.  86.1810-01 is not applicable, this is indicated by the statement 
``[Reserved].'' This section applies to model year 2009 and later 
light-duty vehicles and light-duty trucks fueled by gasoline, diesel, 
methanol, ethanol, natural gas and liquefied petroleum gas fuels. This 
section also applies to MDPVs and complete heavy-duty vehicles 
certified according to the provisions of this subpart. Multi-fueled 
vehicles (including dual-fueled and flexible-fueled vehicles) shall 
comply with all requirements established for each consumed fuel (or 
blend of fuels in the case of flexible fueled vehicles). The standards 
of this subpart apply to both certification and in-use vehicles unless 
otherwise indicated. This section also applies to hybrid electric 
vehicles and zero emission vehicles. Unless otherwise specified, 
requirements and provisions of this subpart applicable to methanol 
fueled vehicles are also applicable to Tier 2 and interim non-Tier 2 
ethanol fueled vehicles.

    (a) through (e) [Reserved]. For guidance see Sec.  86.1810-01.
    (f) Altitude requirements. (1) All emission standards apply at low 
altitude conditions and at high altitude conditions, except for 
supplemental exhaust emission standards, cold temperature NMHC emission 
standards, and the evaporative emission standards as described in Sec.  
86.1811-09(e). Supplemental exhaust emission standards, as described in 
Sec.  86.1811-04(f), apply only at low altitude conditions. Cold 
temperature NMHC emission standards, as described in Sec.  86.1811-
10(g), apply only at low altitude conditions. Tier 2 evaporative 
emission standards apply at high altitude conditions as specified in 
Sec.  86.1810-01(f) and (j), and Sec.  86.1811-04(e).
    (2) For vehicles that comply with the cold temperature NMHC 
standards, manufacturers shall submit an engineering evaluation 
indicating that common calibration approaches are utilized at high 
altitudes. Any deviation from low altitude emission control practices 
shall be included in the auxiliary emission control device (AECD) 
descriptions submitted at certification. Any AECD specific to high 
altitude shall require engineering emission data for EPA evaluation to 
quantify any emission impact and validity of the AECD.
    (g) through (p) [Reserved]. For guidance see Sec.  86.1810-01.
    18. Section 86.1811-04 is amended by adding paragraphs (k)(5)(iv)

    19. A new Sec.  86.1811-09 is added to Subpart S to read as follows:

Sec.  86.1811-09  Emission standards for light-duty vehicles, light-
duty trucks and medium-duty passenger vehicles.

    Section 86.1811-09 includes text that specifies requirements that 
differ from Sec.  86.1811-04. Where a paragraph in Sec.  86.1811-04 is 
identical and applicable to Sec.  86.1811-09, this may be indicated by

    (t) Evaporative emission in-use standards. (1) For LDVs and LLDTs 
certified prior to the 2012 model year, the Tier 2 LDV/LLDT evaporative 
emissions standards in Table S04-3 of Sec.  86.1811-04(e) shall apply 
to in-use vehicles for only the first three model years after an 
evaporative family is first certified to the LDV/LLDT evaporative 
emission standards in Table S09-1 of paragraph (e) of this section. For 
example, evaporative families first certified to the LDV/LLDT standards 
in Table S09-1 in the 2011 model year shall meet the Tier 2 LDV/LLDT 
evaporative emission standards (Table S04-3) in-use for 2011, 2012, and 
2013 model year vehicles (applying Tier 2 standards in-use is limited 
to the first three years after introduction of a vehicle).
    (2) For HLDTs and MDPVs certified prior to the 2013 model year, the 
Tier 2 HLDT/MDPV evaporative emissions standards in Table S04-3 of 
Sec.  86.1811-04(e) shall apply to in-use vehicles for only the first 
three model years after an evaporative family is first certified to the 
HLDT/MDPV evaporative emission standards in Table S09-1 of paragraph 
(e) of this section. For example, evaporative families first certified 
to the HLDT/MDPV standards in Table S09-1 in the 2012 model year shall 
meet the Tier 2 HLDT/MDPV evaporative emission standards (Table S04-3) 
in-use for 2012, 2013, and 2014 model year vehicles (applying Tier 2 
standards in-use is limited to the first three years after introduction 
of a vehicle).
    20. A new Sec.  86.1811-10 is added to Subpart S to read as follows:

Sec.  86.1811-10  Emission standards for light-duty vehicles, light-
duty trucks and medium-duty passenger vehicles.

    Section 86.1811-10 includes text that specifies requirements that 
differ from Sec.  86.1811-04 and Sec.  86.1811-09. Where a paragraph in 
Sec.  86.1811-04 or Sec.  86.1811-09 is identical and applicable to 
Sec.  86.1811-10, this may be indicated by specifying the corresponding 
paragraph and the statement ``[Reserved]. For guidance see Sec.  
86.1811-04'' or ``[Reserved]. For guidance see Sec.  86.1811-09.'' 
Where a corresponding paragraph of Sec.  86.1811-04 or Sec.  86.1811-09 
is not applicable, this is indicated by the statement ``[Reserved].''
    (a) [Reserved]. For guidance see Sec.  86.1811-09.
    (b) through (d) [Reserved]. For guidance see Sec.  86.1811-04.
    (e) [Reserved]. For guidance see Sec.  86.1811-09.
    (f) [Reserved]. For guidance see Sec.  86.1811-04.
    (g) Cold temperature exhaust emission standards. (1) Cold 
temperature CO standards. These cold temperature CO standards are 
applicable only to gasoline fueled LDV/Ts and MDPVs. For the following 
cold temperature CO exhaust emission standards, a useful life of 50,000 
miles or 5 years (whichever occurs first) applies:
    (i) For LDVs and LDT1s, the standard is 10.0 grams per mile CO.
    (ii) For LDT2s, LDT3s and LDT4s, and MDPVs the standard is 12.5 
grams per mile CO.
    (iii) These standards do not apply to interim non-Tier 2 MDPVs.
    (2) Cold temperature NMHC standards. Full useful life fleet average 
cold temperature NMHC standards are applicable only to gasoline fueled 
LDV/LLDTs and HLDT/MDPVs, and apply equally to certification and in-use 
except as otherwise specified in paragraph (u) of this section for in-
use standards for applicable phase-in models. Testing with other fuels 
such as E85, or testing on diesel vehicles, is not required. Multi-
fuel, bi-fuel or dual-fuel vehicles must comply with requirements using 
gasoline only. For LDV/LLDTs, the useful life is 120,000 miles or 10 
years, whichever comes first. For HLDT/MDPVs, the useful life is 
120,000 miles or 11 years, whichever comes first. There is not an 
intermediate

useful life standard for cold temperature NMHC standards.
    (i) The standards are shown in Table S10-1, which follows:

------------------------------------------------------------------------

    (ii) The manufacturer must calculate its fleet average cold 
temperature NMHC emission level(s) as described in Sec.  86.1864-10(m).
    (iii) During a phase-in year, the manufacturer must comply with the 
fleet average standards for the required phase-in percentage for that 
year as specified in paragraph (g)(3) of this section, or for the 
alternate phase-in percentage as permitted under paragraph (g)(4) of 
this section.
    (iv) For model years prior to 2010 (LDV/LLDTs) and 2012 (HLDT/
MDPVs), where the manufacturer desires to bank early NMHC credits as 
permitted under Sec.  86.1864-10(o)(5), the manufacturer must achieve a 
fleet average standard below 0.3 grams per mile for LDV/LLDTs and below 
0.5 grams per mile for HLDT/MDPVs. Manufacturers must determine 
compliance with the cold temperature NMHC fleet average standard 
according to Sec.  86.1864-10(o).
    (3) Phase-in of the cold temperature NMHC standards. Except as 
permitted in Sec.  86.1811-04(k)(5)(vi) and (vii) regarding small 
volume manufacturers, manufacturers must comply with the phase-in 
requirements in Tables S10-2 and S10-3 of this paragraph. Separate 
phase-in schedules are provided for LDV/LLDTs and for HLDT/MDPVs. These 
requirements specify the minimum percentage of the manufacturer's LDV/
LLDT and HLDT/MDPV 50-State sales, by model year, that must meet the 
fleet average cold temperature NMHC standard for their full useful 
lives. LDVs and LLDTs must be grouped together to determine compliance 
with these phase-in requirements, and HLDTs and MDPVs must also be 
grouped together to determine compliance with these phase-in 
requirements. Tables S10-2 and S10-3 follow:

    (4) Alternate phase-in schedules for cold temperature NMHC 
standards. (i) Manufacturers may apply for alternative phase-in 
schedules that would still result in 100% phase-in by 2013 and 2015, 
respectively, for LDV/LLDTs and HLDT/MDPVs. An alternate phase-in 
schedule submitted by a manufacturer is subject to EPA approval. The 
alternative phase-in will not be used to delay full implementation past 
the last year of the primary phase-in schedule (2013 for LDV/LLDTs, 
2015 for HLDT/MDPVs). An alternative phase-in schedule will be 
acceptable if it satisfies the following equations:

LDV/LLDTs:

(6xAPI2008) + (5xAPI2009) + 
(4xAPI2010) + (3xAPI2011) + 
(2xAPI2012) + (1xAPI2013) >=500%

HLDT/MDPVs:

(6xAPI2010) + (5xAPI2011) + 
(4xAPI2012) + (3xAPI2013) + 
(2xAPI2014) + (1xAPI2015) >=500%

Where:

API = anticipated phase-in percentage for the referenced model year

    (ii) If the sum of products is greater than or equal to 500%, which 
is the sum of products from the primary phase-in schedule (4 x 25% + 3 
x 50% + 2 x 75% + 1 x 100% = 500%), then the alternative phase-in 
schedule is acceptable, except as prohibited in paragraphs (g)(4)(i) 
and (iii) of this section. In addition, manufacturers electing to use 
an alternate phase-in schedule for compliance with the cold temperature 
NMHC exhaust emission standards must ensure that the sum of products is 
at least 100% for model years 2010 and earlier for LDV/LLDTs, and 2012 
and earlier for HLDT/MDPVs. For example, a phase-in schedule for LDV/
LLDTs of 5/10/10/45/80/100 that begins in 2008 would calculate as (6 x 
5%) + (5 x 10%) + (4 x 10%) = 120% and would be acceptable for 2008-
2010. The full phase-in would calculate as (6 x 5%) + (5 x 10%) + (4 x 
10%) + (3 x 45%) + (2 x 80%) + (1 x 100%) = 515% and would be 
acceptable for 2008-2013.
    (iii) Under an alternate phase-in schedule, the projected phase-in 
percentage is not binding for a given model year, provided the sums of 
the actual phase-in percentages that occur meet the appropriate total 
sums as required in the equations of paragraph (g)(4)(i) of this 
section, and provided that 100% actual compliance is reached for the 
appropriate model year, either 2013 for LDV/LLDTs or 2015 for HLDT/MDPVs.
    (5) Manufacturers must determine compliance with required phase-in 
schedules as follows:
    (i) Manufacturers must submit information showing compliance with 
all phase-in requirements of this section with their Part I 
applications as required by Sec.  86.1844(d)(13).
    (ii) A manufacturer electing to use any alternate phase-in schedule 
permitted under this section must provide in its Application for 
Certification for the first year in which it intends to use such a 
schedule, and in each succeeding year during the phase-in, the intended 
phase-in percentages for that model year and the remaining phase-in 
years along with the intended final sum of those percentages as 
described in paragraph (g)(4)(i) of this section. This information may 
be included with the information required under Sec.  86.1844-
01(d)(13). In its year end annual reports, as required under Sec.  
86.1844-01(e)(4), the manufacturer must include sufficient information 
so that the Administrator can verify compliance with the alternative 
phase-in schedule established under paragraph (g)(4)(i) of this section.
    (6)(i) Sales percentages for the purpose of determining compliance 
with the phase-in of the cold temperature NMHC requirements must be 
based upon projected 50-State sales of LDV/LLDTs and HLDT/MDPVs of the 
applicable model year by the manufacturer to the point of first sale. 
Such sales percentages must be rounded to the nearest one tenth of a 
percent.
    (ii) Alternatively, the manufacturer may petition the Administrator 
to allow actual volume produced for U.S. sales to be used in lieu of 
projected U.S. sales for purposes of determining compliance

[[Page 15958]]

with the phase-in percentage requirements under this section. The 
manufacturer must submit its petition within 30 days of the end of the 
model year to the Compliance and Innovative Strategies Division. For 
EPA to approve the use of actual volume produced for U.S. sales, the 
manufacturer must establish to the satisfaction of the Administrator, 
that actual production volume is functionally equivalent to actual 
sales volume of LDV/LLDTs and HLDT/MDPVs sold in all 50 U.S. States.
    (f) through (s) [Reserved]. For guidance see Sec.  86.1811-04.
    (t) [Reserved]. For guidance see Sec.  86.1811-09.
    (u) Cold temperature NMHC exhaust emission in-use standards for 
applicable phase-in models. An interim full useful life in-use 
compliance standard is calculated by adding 0.1 g/mi to the FEL to 
which each test group is newly certified, and applies to that test 
group only for the model years shown in Tables S10-4 and S10-5. 
Otherwise, the in-use standard is the certification standard from 
paragraph (g)(2) of this section. The standards apply for purposes of 
in-use testing only and does not apply to certification or Selective 
Enforcement Auditing. Tables S10-4 and S10-5 follow:

    21. Section 86.1823-01 is amended by revising paragraph 
(a)(3)(i)(C) to read as follows:

Sec.  86.1823-01  Durability demonstration procedures for exhaust emissions.

* * * * *
    (a) * * *
    (3) * * *
    (i) * * *
    (C) The DF calculated by these procedures will be used for 
determining compliance with FTP exhaust emission standards, SFTP 
exhaust emission standards, cold temperature NMHC emission standards, 
and cold CO emission standards. At the manufacturer's option and using 
procedures approved by the Administrator, a separate DF may be 
calculated exclusively using cold CO test data to determine compliance 
with cold CO emission standards. Similarly, at the manufacturer's 
option and using procedures approved by the Administrator, a separate 
DF may be calculated exclusively using cold temperature NMHC test data 
to determine compliance with cold temperature NMHC emission standards. 
For determining compliance with full useful life cold NMHC emission 
standards, the 68-86 degree F 120,000 mile full useful life NMOG DF may 
be used. Also at the manufacturer's option and using procedures 
approved by the Administrator, a separate DF may be calculated 
exclusively using US06 and/or air conditioning (SC03) test data to 
determine compliance with the SFTP emission standards.
* * * * *
    22. Section 86.1827-01 is amended by revising paragraph (a)(5) to 
read as follows:

Sec.  86.1827-01  Test group determination.

* * * * *
    (a) * * *
    (5) Subject to the same emission standards (or FEL in the case of 
cold temperature NMHC standards), except that a manufacturer may 
request to group vehicles into the same test group as vehicles subject 
to more stringent standards, so long as all the vehicles within the 
test group are certified to the most stringent standards applicable to 
any vehicle within that test group. Light-duty trucks which are subject 
to the same emission standards as light-duty vehicles with the 
exception of the light-duty truck idle CO standard and/or total HC 
standard may be included in the same test group.
* * * * *
    23. A new Sec.  86.1828-10 is added to Subpart S to read as follows:

Sec.  86.1828-10  Emission data vehicle selection.

    Section 86.1828-10 includes text that specifies requirements that 
differ from Sec.  86.1828-01. Where a paragraph in Sec.  86.1828-01 is 
identical and applicable to Sec.  86.1828-10, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.  86.1828-01.'' Where a corresponding paragraph of 
Sec.  86.1828-01 is not applicable, this is indicated by the statement 
``[Reserved].''
    (a) through (f) [Reserved]. For guidance see Sec.  86.1828-01.
    (g) Cold temperature NMHC testing. For cold temperature NMHC 
exhaust emission compliance for each durability group, the vehicle 
expected to emit the highest NMHC emissions at 20 degrees F on 
candidate in-use vehicles shall be selected from the test vehicles 
specified in Sec.  86.1828-01(a). When the expected worst-case cold 
temperature NMHC vehicle is also the expected worst-case cold CO 
vehicle as selected in paragraph (c) of this section, then cold testing 
is required only for that vehicle; otherwise, testing is required for 
both the worst-case cold CO vehicle and the worst-case cold temperature 
NMHC vehicle.
    24. Section 86.1829-01 is amended by revising paragraph (b)(3) to 
read as follows:

* * * * *
    (b) * * *
    (3) Cold temperature CO and cold temperature NMHC Testing. One EDV

temperature NMHC exhaust emission compliance in accordance with the 
test procedures in subpart C of this part or with alternative 
procedures requested by the manufacturer and approved in advance by the 
Administrator. The selection of which EDV and test group within the 
durability group will be tested for cold temperature CO and cold 
temperature NMHC compliance will be determined under the provisions of 
Sec.  86.1828-10(c) and (g).
* * * * *
    25. Section 86.1844-01 is amended by revising paragraph (d)(11) to 
read as follows:

Sec.  86.1844-01  Information requirements: Application for 
certification and submittal of information upon request.

* * * * *
    (d) * * *
    (11) A list of all auxiliary emission control devices (AECD) 
installed on any applicable vehicles, including a justification for 
each AECD, the parameters they sense and control, a detailed 
justification of each AECD which results in a reduction in 
effectiveness of the emission control system, and rationale for why the 
AECD is not a defeat device as defined under Sec. Sec.  86.1809-01 and 
86.1809-10. For any AECD uniquely used at high altitudes, EPA may 
request engineering emission data to quantify any emission impact and 
validity of the AECD. For any AECD uniquely used on multi-fuel vehicles 
when operated on fuels other than gasoline, EPA may request engineering 
emission data to quantify any emission impact and validity of the AECD.

    26. A new Sec.  86.1848-10 is added to Subpart S to read as follows:

Sec.  86.1848-10  Certification.

    Section 86.1848-10 includes text that specifies requirements that 
differ from Sec.  86.1848-01. Where a paragraph in Sec.  86.1848-01 is 
identical and applicable to Sec.  86.1848-10, this may be indicated by 
specifying the corresponding paragraph and the statement ``[Reserved]. 
For guidance see Sec.  86.1848-01.'' Where a corresponding paragraph of 
Sec.  86.1848-01 is not applicable, this is indicated by the statement 
``[Reserved].''
    (a) through (b) [Reserved]. For guidance see Sec.  86.1848-01.
    (c) All certificates are conditional upon the following conditions 
being met:
    (1) The manufacturer must supply all required information according 
to the provisions of Sec. Sec.  86.1843-01 and 86.1844-01.

during and after model year production.
    (3) The manufacturer must comply with all implementation schedules 
sales percentages as required in Sec.  86.1810 or elsewhere in this 
part. Failure to meet a required implementation schedule sales 
percentage will be considered to be a failure to satisfy a condition 
upon which the certificate was issued and any vehicles or trucks sold 
in violation of the implementation schedule shall not be covered by the 
certificate.
    (4) For incomplete light-duty trucks and incomplete heavy-duty 
vehicles, a certificate covers only those new motor vehicles which, 
when completed by having the primary load-carrying device or container 
attached, conform to the maximum curb weight and frontal area 
limitations described in the application for certification as required 
in Sec.  86.1844-01.
    (5) The manufacturer must meet the in-use testing and reporting 
requirements contained in Sec. Sec.  86.1845-01, 86.1846-01, and 
86.1847-01, as applicable. Failure to meet the in-use testing or 
reporting requirements shall be considered a failure to satisfy a 
condition upon which the certificate was issued. A vehicle or truck 
will be considered to be covered by the certificate only if the 
manufacturer fulfills this condition upon which the certificate was issued.
    (6) Vehicles are covered by a certificate of conformity only if 
they are in all material respects as described in the manufacturer's 
application for certification (Part I and Part II).
    (7) For Tier 2 and interim non-Tier 2 vehicles, all certificates of 
conformity issued are conditional upon compliance with all provisions 
of Sec. Sec.  86.1811-04, 86.1860-04, 86.1861-04 and 86.1862-04 both 
during and after model year production.
    (i) Failure to meet the fleet average NOX requirements 
of 0.07g/mi, 0.30 g/mi or 0.20 g/mi, as applicable, will be considered 
to be a failure to satisfy the terms and conditions upon which the 
certificate(s) was (were) issued and the vehicles sold in violation of 
the fleet average NOX standard will not be covered by the 
certificate(s).
    (ii) Failure to comply fully with the prohibition against selling 
credits that it has not generated or that are not available, as 
specified in Sec.  86.1861-04, will be considered to be a failure to 
satisfy the terms and conditions upon which the certificate(s) was 
(were) issued and the vehicles sold in violation of this prohibition 
will not be covered by the certificate(s).
    (iii) Failure to comply fully with the phase-in requirements of 
Sec.  86.1811-04, will be considered to be a failure to satisfy the 
terms and conditions upon which the certificate(s) was (were) issued 
and the vehicles sold which do not comply with Tier 2 or interim non-
Tier 2 requirements, up to the number needed to comply, will not be 
covered by the certificate(s).
    (iv) For paragraphs (c)(7)(i) through (iii) of this section:
    (A) The manufacturer must bear the burden of establishing to the 
satisfaction of the Administrator that the terms and conditions upon 
which the certificate(s) was (were) issued were satisfied.
    (B) For recall and warranty purposes, vehicles not covered by a 
certificate of conformity will continue to be held to the standards 
stated or referenced in the certificate that otherwise would have 
applied to the vehicles.
    (8) For LDV/LLDTs and HLDT/MDPVs, all certificates of conformity 
issued are conditional upon compliance with all provisions of 
Sec. Sec.  86.1811-10 and 86.1864-10 both during and after model year 
production.
    (i) Failure to meet the fleet average cold temperature NMHC 
requirements will be considered a failure to satisfy the terms and 
conditions upon which the certificate(s) was (were) issued and the 
vehicles sold in violation of the fleet average NMHC standard will not 
be covered by the certificate(s).
    (ii) Failure to comply fully with the prohibition against selling 
credits that are not generated or that are not available, as specified 
in Sec.  86.1864-10, will be considered a failure to satisfy the terms 
and conditions upon which the certificate(s) was (were) issued and the 
vehicles sold in violation of this prohibition will not be covered by 
the certificate(s).
    (iii) Failure to comply fully with the phase-in requirements of 
Sec.  86.1811-10 will be considered a failure to satisfy the terms and 
conditions upon which the certificate(s) was (were) issued and the 
vehicles sold that do not comply with cold temperature NMHC 
requirements, up to the number needed to comply, will not be covered by 
the certificate(s).
    (iv) For paragraphs (c)(8)(i) through (iii) of this section:
    (A) The manufacturer bears the burden of establishing to the 
satisfaction of the Administrator that the terms and conditions upon 
which the certificate(s) was (were) issued were satisfied.
    (B) For recall and warranty purposes, vehicles not covered by a 
certificate of conformity will continue to be held to the standards 
stated or referenced in the

[[Page 15960]]

certificate that otherwise would have applied to the vehicles.
    (d) through (i) [Reserved]. For guidance see Sec.  86.1848-01.
    27. A new Sec.  86.1864-10 is added to Subpart S to read as follows:

Sec.  86.1864-10   How to comply with the fleet average cold 
temperature NMHC standards.

    (a) Applicability. Cold temperature NMHC exhaust emission standards 
apply to the following vehicles, subject to the phase-in requirements 
in Sec.  86.1811-10(g)(3) and (4):
    (1) 2010 and later model year LDV/LLDTs.
    (2) 2012 and later model year HLDT/MDPVs.
    (3) Aftermarket conversion systems as defined in 40 CFR 85.502, 
including conversion of MDPVs.
    (4) Vehicles imported by ICIs as defined in 40 CFR 85.1502.
    (b) Useful life requirements. Full useful life requirements for 
cold temperature NMHC standards are defined in Sec.  86.1805-04(g). 
There is not an intermediate useful life standard for cold temperature 
NMHC standards.
    (c) Altitude. Altitude requirements for cold temperature NMHC 
standards are provided in Sec.  86.1810-09(f).
    (d) Small volume manufacturer certification procedures. 
Certification procedures for small volume manufacturers are provided in 
Sec.  86.1838-01.
    (e) Cold temperature NMHC standards. Fleet average cold temperature 
NMHC standards are provided in Sec.  86.1811-10(g)(2).
    (f) Phase-in. Phase-in of the cold temperature NMHC standards are 
provided in Sec.  86.1811-10(g)(3) and (4).
    (g) Phase-in flexibilities for small volume manufacturers. Phase-in 
flexibilities for small volume manufacturer compliance with the cold 
temperature NMHC standards are provided in Sec.  86.1811-04(k)(5).
    (h) Hardship provisions for small volume manufacturers. Hardship 
provisions for small volume manufacturers related to the cold 
temperature NMHC standards are provided in Sec.  86.1811-04(q)(1).
    (i) In-use standards for applicable phase-in models. In-use cold 
temperature NMHC standards for applicable phase-in models are provided 
in Sec.  86.1811-10(u).
    (j) Durability procedures and method of determining deterioration 
factors (DFs). The durability data vehicle selection procedures of 
Sec.  86.1822-01 and the durability demonstration procedures of Sec.  
86.1823-06 apply for cold NMHC standards. For determining compliance 
with full useful life cold temperature NMHC emission standards, the 68-
86 degree F, 120,000 mile full useful life NMOG DF may be used.
    (k) Vehicle test procedure. (1) The test procedure for 
demonstrating compliance with cold temperature NMHC standards is 
contained in subpart C of this part. With prior EPA approval, 
alternative testing procedures may be used, as specified in Sec.  
86.106-96(a), provided cold temperature NMHC emissions do not decrease 
as a result of an alternative testing procedure.
    (2) Testing of all LDVs, LDTs and MDPVs to determine compliance 
with cold temperature NMHC exhaust emission standards set forth in this 
section must be on a loaded vehicle weight (LVW) basis, as defined in 
Sec.  86.1803-01.
    (3) Testing for the purpose of providing certification data is 
required only at low altitude conditions and only for vehicles that can 
operate on gasoline, except as requested in Sec. Sec.  86.1810-09(f) 
and 86.1844-01(d)(11). If hardware and software emission control 
strategies used during low altitude condition testing are not used 
similarly in-use across all altitudes, the manufacturer will include a 
statement in the application for certification, in accordance with 
Sec. Sec.  86.1844-01(d)(11) and Sec.  86.1810-09(f), stating what the 
different strategies are and why they are used. If hardware and 
software emission control strategies used during testing with gasoline 
are not used similarly with all fuels that can be used in multi-fuel 
vehicles, the manufacturer will include a statement in the application 
for certification, in accordance with Sec. Sec.  86.1844-01(d)(11) and 
86.1810-09(f), stating what the different strategies are and why they 
are used. For example, unless a manufacturer states otherwise, air 
pumps used to control emissions on dedicated gasoline vehicles or 
multi-fuel vehicles during low altitude conditions must also be used to 
control emissions at high altitude conditions, and software used to 
control emissions or closed loop operation must also operate similarly 
at low and high altitude conditions and similarly when multi-fueled 
vehicles are operated on gasoline and alternate fuels. These examples 
are for illustrative purposes only; similar strategies would apply to 
other currently used emission control technologies and/or emerging or 
future technologies.
    (l) Emission data vehicle (EDV) selection. Provisions for selecting 
the appropriate EDV for the cold temperature NMHC standards are 
provided in Sec. Sec.  86.1828-10(g) and 86.1829-01(b)(3).
    (m) Calculating the fleet average cold temperature NMHC standard. 
Manufacturers will compute separate sales-weighted fleet average cold 
temperature NMHC emissions at the end of the model year for LDV/LLDTs 
and HLDT/MDPVs, using actual sales, and certifying test groups to FELs, 
as defined in Sec.  86.1803-01. The FEL becomes the standard for each 
test group, and every test group can have a different FEL. The 
certification resolution for the FEL will be one decimal point. LDVs 
and LLDTs must be grouped together when calculating the fleet average, 
and HLDTs and MDPVs must also be grouped together to determine the 
fleet average. Manufacturers must compute the sales-weighted cold 
temperature NMHC fleet averages using the following equation, rounded 
to the nearest tenth:

Fleet average cold temperature NMHC exhaust emissions =

[Sigma](N x FEL) / Total number of vehicles sold of the applicable 
weight category (i.e., either LDV + LLDTs, or HLDT + MDPVs)

Where:

N = The number of LDVs and LLDTs, or HLDTs and MDPVs, sold within the 
applicable FEL, based on vehicles counted to the point of first sale.

FEL = Family Emission Limit.

    (n) Certification compliance and enforcement requirements for cold 
temperature NMHC standards. (1) In addition to the compliance and 
enforcement requirements provided throughout Sec.  86.1864-10, 
additional conditions are included in the provisions of Sec.  86.1848-
10(c)(8).
    (2) The certificate issued for each test group requires all 
vehicles within that test group to meet the emission standard or FEL to 
which the vehicles were certified.
    (3) Each manufacturer must comply with the applicable cold 
temperature NMHC fleet average standard on a sales-weighted average 
basis, at the end of each model year, using the procedure described in 
paragraph (m) of this section.
    (4) During a phase-in year, the manufacturer must comply with the 
applicable cold temperature NMHC fleet average standard for the 
required phase-in percentage for that year as specified in Sec.  
86.1811-10(g)(3) or (4).
    (5) Manufacturers must compute separate cold temperature NMHC fleet 
averages for LDV/LLDTs and HLDT/MDPVs. The sales-weighted cold 
temperature NMHC fleet averages must be compared with the applicable 
fleet average standard.

[[Page 15961]]

    (6) Each manufacturer must comply on an annual basis with the fleet 
average standards as follows:
    (i) Manufacturers must report in their annual reports to the Agency 
that they met the relevant corporate average standard by showing that 
their sales-weighted average cold temperature NMHC emissions of LDV/
LLDTs and HLDT/MDPVs, as applicable, are at or below the applicable 
fleet average standard;
    (ii) If the sales-weighted average is above the applicable fleet 
average standard, manufacturers must obtain and apply sufficient NMHC 
credits, as appropriate, and as permitted under paragraph (o)(8) of 
this section. A manufacturer must show via the use of credits that they 
have offset any exceedence of the corporate average standard. 
Manufacturers shall also report their credit balances or deficits.
    (iii) If a manufacturer fails to meet the corporate average cold 
temperature NMHC standard for two consecutive years, as required in 
paragraph (o)(8) of this section, the vehicles causing the corporate 
average exceedence will be considered not covered by the certificate of 
conformity. A manufacturer will be subject to penalties on an 
individual-vehicle basis for sale of vehicles not covered by a certificate.
    (iv) EPA will review each manufacturer's sales to designate the 
vehicles that caused the exceedence of the corporate average standard. 
EPA will designate as nonconforming those vehicles in test groups with 
the highest certification emission values first, continuing until a 
number of vehicles equal to the calculated number of noncomplying 
vehicles as determined above is reached. In a group where only a 
portion of vehicles would be deemed nonconforming, EPA will determine 
the actual nonconforming vehicles by counting backwards from the last 
vehicle produced in that test group. Manufacturers will be liable for 
penalties for each vehicle sold that is not covered by a certificate.
    (o) How does the cold temperature NMHC averaging, banking and 
trading (ABT) program work? (1) Manufacturers shall average the cold 
temperature NMHC emissions of their vehicles and comply with the cold 
temperature NMHC fleet average corporate standard. Credits may be 
generated during and after the phase-in period. Credits may also be 
generated prior to the phase-in periods as described in paragraph (5) 
of this section. A manufacturer whose cold temperature NMHC fleet 
average emissions exceed the 0.3 g/mile standard for LDV/LLDTs, or 0.5 
g/mi for HLDT/MDPVs, must complete the calculation in paragraph (o)(4) 
of this section to determine the size of its NMHC credit deficit. A 
manufacturer whose cold temperature NMHC fleet average emissions are 
less than the 0.3 g/mile standard for LDV/LLDTs, or less than 0.5 g/mi 
for HLDT/MDPVs, must complete the calculation in paragraph (o)(4) of 
this section if it desires to generate NMHC credits.
    (2) There are no property rights associated with NMHC credits 
generated under this subpart. Credits are a limited authorization to 
emit the designated amount of emissions. Nothing in this part or any 
other provision of law should be construed to limit EPA's authority to 
terminate or limit this authorization through a rulemaking.
    (3) Each manufacturer must comply with the reporting and 
recordkeeping requirements of paragraph (p) of this section for NMHC 
credits, including early credits. The averaging, banking and trading 
program shall be enforced through the certificate of conformity that 
allows the manufacturer to introduce any regulated vehicles into commerce.
    (4) Credits are earned on the last day of the model year. 
Manufacturers must calculate, for a given model year, the number of 
credits or debits it has generated according to the following equation, 
rounded to the nearest tenth:

NMHC Credits or Debits = (Cold Temperature NMHC Standard-Manufacturer's 
Sales-Weighted Fleet Average Cold Temperature NMHC Emissions) x (Total 
Number of Vehicles Sold)

Where:

Cold Temperature NMHC Standard = 0.3 g/mi for LDV/LLDTs or 0.5 g/mi for 
HLDT/MDPV, per Sec.  86.1811-10(g)(2).

Manufacturer's Sales-Weighted Fleet Average Cold Temperature NMHC 
Emissions = average calculated according to paragraph (m) of this section.
Total Number of Vehicles Sold = Total 50-State sales based on the point 
of first sale.

    (5) The following provisions apply for early banking:
    (i) Manufacturers may certify LDV/LLDTs to the cold temperature 
NMHC exhaust standards in Sec.  86.1811-10(g)(2) for model years 2008-
2009 in order to bank credits for use in the 2010 and later model 
years. Manufacturers may certify HLDT/MDPVs to the cold temperature 
NMHC exhaust standards in Sec.  86.1811-10(g)(2) for model years 2010-
2011 in order to bank credits for use in the 2012 and later model years.
    (ii) This process is referred to as ``early banking'' and the 
resultant credits are referred to as ``early credits.'' In order to 
bank early credits, a manufacturer must comply with all exhaust 
emission standards and requirements applicable to LDV/LLDTs and/or 
HLDT/MDPVs. To generate early credits, a manufacturer must separately 
compute the sales-weighted cold temperature NMHC average of the LDV/
LLDTs and HLDT/MDPVs it certifies to the exhaust requirements and 
separately compute credits using the calculations in paragraph (o)(4) 
of this section. Early HLDT/MDPV credits may not be applied to LDV/
LLDTs before the 2010 model year. Early LDV/LLDT credits may not be 
applied to HLDT/ MDPV before the 2012 model year.
    (6) NMHC credits are not subject to any discount or expiration date 
except as required under the deficit carryforward provisions of 
paragraph (o)(8) of this section. There shall be no discounting of 
unused credits. NMHC credits shall have unlimited lives, subject to the 
limitations of paragraph (o)(2) of this section.
    (7) Credits may be used as follows:
    (i) Credits generated and calculated according to the method in 
paragraph (o)(4) of this section may only be used to offset deficits 
accrued with respect to the standard in Sec.  86.1811-10(g)(2). Credits 
may be banked and used in a future model year in which a manufacturer's 
average cold temperature NMHC level exceeds the 0.3 or 0.5 g/mi 
standard for LDV/LLDTs and HLDT/MDPVs, respectively. Credits may be 
exchanged between the LDT/LLDT and HLDT/MDPV fleets of a given 
manufacturer. Credits may also be traded to another manufacturer 
according to the provisions in paragraph (o)(9) of this section. Before 
trading or carrying over credits to the next model year, a manufacturer 
must apply available credits to offset any credit deficit, where the 
deadline to offset that credit deficit has not yet passed.
    (ii) The use of credits shall not be permitted to address Selective 
Enforcement Auditing or in-use testing failures. The enforcement of the 
averaging standard shall occur through the vehicle's certificate of 
conformity. A manufacturer's certificate of conformity shall be 
conditioned upon compliance with the averaging provisions. The 
certificate shall be void ab initio if a manufacturer fails to meet the 
corporate average standard and does not obtain appropriate credits to 
cover its shortfalls in that model year or in the subsequent model year 
(see deficit carryforward provision in paragraph (o)(8) of this 
section). Manufacturers shall track their

[[Page 15962]]

certification levels and sales unless they produce only vehicles 
certified to cold temperature NMHC levels below the standard and do not 
plan to bank credits.
    (8) The following provisions apply if debits are accrued:
    (i) If a manufacturer calculates that it has negative credits (also 
called ``debits'' or a ``credit deficit'') for a given model year, it 
shall be allowed to carry that deficit forward into the next model 
year. Such a carry-forward may only occur after the manufacturer 
exhausts any supply of banked credits. At the end of that next model 
year, the deficit must be covered with an appropriate number of credits 
that the manufacturer generates or purchases. Any remaining deficit 
shall be subject to an enforcement action, as described in this 
paragraph (o)(8). Manufacturers are not permitted to run a deficit for 
two consecutive years.
    (ii) If debits are not offset within the specified time period, the 
number of vehicles not meeting the fleet average cold temperature NMHC 
standards and not covered by the certificate must be calculated by 
dividing the total amount of debits for the model year by the fleet 
average cold temperature NMHC standard applicable for the model year in 
which the debits were first incurred.
    (iii) EPA will determine the number of vehicles for which the 
condition on the certificate was not satisfied by designating vehicles 
in those test groups with the highest certification cold temperature 
NMHC emission values first and continuing until a number of vehicles 
equal to the calculated number of noncomplying vehicles as determined 
above is reached. If this calculation determines that only a portion of 
vehicles in a test group contribute to the debit situation, then EPA 
will designate actual vehicles in that test group as not covered by the 
certificate, starting with the last vehicle produced and counting backwards.
    (iv)(A) If a manufacturer ceases production of LDV/LLDTs and HLDT/
MDPVs, the manufacturer continues to be responsible for offsetting any 
debits outstanding within the required time period. Any failure to 
offset the debits will be considered a violation of paragraph (o)(8)(i) 
of this section and may subject the manufacturer to an enforcement 
action for sale of vehicles not covered by a certificate, pursuant to 
paragraphs (o)(8)(ii) and (iii) of this section.
    (B) If a manufacturer is purchased by, merges with, or otherwise 
combines with another manufacturer, the controlling entity is 
responsible for offsetting any debits outstanding within the required 
time period. Any failure to offset the debits will be considered a 
violation of paragraph (o)(8)(i) of this section and may subject the 
manufacturer to an enforcement action for sale of vehicles not covered 
by a certificate, pursuant to paragraphs (o)(8)(ii) and (iii) of this 
section.
    (v) For purposes of calculating the statute of limitations, a 
violation of the requirements of paragraph (o)(8)(i) of this section, a 
failure to satisfy the conditions upon which a certificate(s) was 
issued and hence a sale of vehicles not covered by the certificate, all 
occur upon the expiration of the deadline for offsetting debits 
specified in paragraph (o)(8)(i) of this section.
    (9) The following provisions apply to NMHC credit trading:
    (i) EPA may reject NMHC credit trades if the involved manufacturers 
fail to submit the credit trade notification in the annual report. A 
manufacturer may not sell credits that are not available for sale 
pursuant to the provisions in paragraphs (o)(7)(i) of this section.
    (ii) In the event of a negative credit balance resulting from a 
transaction that a manufacturer could not cover by the reporting 
deadline for the model year in which the trade occurred, both the buyer 
and seller are liable, except in cases involving fraud. EPA may void ab 
initio the certificates of conformity of all engine families 
participating in such a trade.
    (iii) A manufacturer may only trade credits that it has generated 
pursuant to paragraph (o)(4) of this section or acquired from another 
party.
    (p) Maintenance of records and submittal of information relevant to 
compliance with fleet average cold temperature NMHC standards--(1) 
Maintenance of records. (i) Manufacturers producing any light-duty 
vehicles, light-duty trucks, or medium-duty passenger vehicles subject 
to the provisions in this subpart must establish, maintain, and retain 
all the following information in adequately organized and indexed

    (iii) Manufacturers must retain all records required to be 
maintained under this section for a period of eight years from the due 
date for the annual report. Records may be stored in any format and on 
any media, as long as manufacturers can promptly send EPA organized, 
written records in English if we ask for them. Manufacturers must keep 
records readily available as EPA may review them at any time.
    (iv) Nothing in this section limits the Administrator's discretion 
to require the manufacturer to retain additional records or submit 
information not specifically required by this section.
    (v) Pursuant to a request made by the Administrator, the 
manufacturer must submit to the Administrator the information that the 
manufacturer is required to retain.
    (vi) EPA may void ab initio a certificate of conformity for 
vehicles certified to emission standards as set forth or otherwise 
referenced in this subpart for which the manufacturer fails to retain 
the records required in this section or to provide such information to 
the Administrator upon request.
    (2) Reporting. (i) Each covered manufacturer must submit an annual 
report. The annual report must contain for each applicable cold 
temperature NMHC standard, the fleet average cold temperature NMHC 
value achieved, all values required to calculate the cold temperature 
NMHC emissions value, the number of credits generated or debits 
incurred, all the values required to calculate the credits or debits, 
the resulting balance of credits or debits, and sufficient information 
to show compliance with all phase-in or alternative phase-in requirements.
    (ii) For each applicable fleet average cold temperature NMHC 
standard, the annual report must also include documentation on all 
credit transactions the manufacturer has engaged in since those 
included in the last report. Information for each transaction must 
include all of the following:
    (A) Name of credit provider.
    (B) Name of credit recipient.
    (C) Date the trade occurred.

    (iii) Unless a manufacturer reports the data required by this 
section in the annual production report required under Sec.  86.1844-
01(e), a manufacturer must submit an annual report for each model year 
after production ends for all affected vehicles produced by the 
manufacturer subject to the provisions of this subpart and no later 
than May 1 of the calendar year following the given model year. Annual 
reports must be submitted to: Director, Compliance and Innovative 
Strategies Division, U.S. Environmental Protection Agency, 2000 
Traverwood, Ann Arbor, Michigan 48105.
    (iv) Failure by a manufacturer to submit the annual report in the 
specified time period for all vehicles subject to the provisions in 
this section is a violation of section 203(a)(1) of the Clean Air Act 
(42 U.S.C. 7522) for each applicable vehicle produced by that manufacturer.
    (v) If EPA or the manufacturer determines that a reporting error 
occurred on an annual report previously submitted to EPA, the 
manufacturer's credit or debit calculations will be recalculated. EPA 
may void erroneous credits, unless traded, and must adjust erroneous 
debits. In the case of traded erroneous credits, EPA must adjust the 
selling manufacturer's credit or debit balance to reflect the sale of 
such credits and any resulting generation of debits.
    (3) Notice of opportunity for hearing. Any voiding of the 
certificate under paragraph (p)(1)(vi) of this section will be made 
only after EPA has offered the affected manufacturer an opportunity for 
a hearing conducted in accordance with Sec.  86.614-84 for light-duty 
vehicles or Sec.  86.1014-84 for light-duty trucks and, if a 
manufacturer requests such a hearing, will be made only after an 
initial decision by the Presiding Officer.
