(a)
Purpose
and Applicability
(1) This section
1961.4 contains the California
"LEV IV" exhaust emission standards for 2026 and subsequent model year
passenger cars (PC), light-duty trucks (LDT), and medium-duty passenger
vehicles (MDPV), and for 2026 and subsequent model year medium-duty vehicles
(MDV). Unless otherwise noted, terms in this section shall have the definitions
provided in Part I, sections B.1 and B.2 of the "California 2026 and Subsequent
Model Year Criteria Pollutant Emission Standards and Test Procedures for
Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles," incorporated by
reference in subsection (c)(1) below. References in this section to "light-duty
vehicle(s)" or "LDV(s)" shall include PCs, LDTs, and MDPVs. A manufacturer must
comply with the exhaust standards in subsections (d) and (e) that are
applicable to specific test groups, and with the fleet average and phase-in
requirements in subsections (d) and (e) that are applicable to the
manufacturer's entire fleet. For purposes of this section
1961.4, all MDPVs are subject to
the requirements of subsection (d) for LDVs and are not subject to the
requirements of subsection (e) for MDVs. The exhaust standards in subsections
(d) and (e) do not apply to ZEVs. ZEVs may not be included in either the
numerator or the denominator of any of the phase-in calculations in subsections
(d) or (e), except as noted in the fleet average requirement of subsection
(d)(1).
(2)
Optional 2025

J.13 of the "California 2026 and Subsequent Model Year Criteria Pollutant
Exhaust Emission Standards and Test Procedures for Passenger Cars, Light-Duty
Trucks, and Medium-Duty Vehicles", separate values for the number of vehicles
in each test group produced and delivered for sale in each individual state or
the District of Columbia.
(4)
Small Volume
Manufacturers
(A) If a manufacturer's
three-year average model year California sales exceeds 4500 units of new LDVs,
MDVs, heavy-duty vehicles, and heavy-duty engines, based on the average number
of vehicles produced and delivered for sale in California for the three
previous consecutive model years, the manufacturer shall no longer be treated
as a small volume manufacturer.
1. If this is
the first time the manufacturer's three-year average exceeds 4500 units, the
manufacturer must comply with the fleet average requirements applicable to a
non-small volume manufacturer, as specified in subsection (d)(1)(A) or
(e)(1)(A), as applicable, beginning with the fourth model year after the last
of the three consecutive model years.
2. If, during the four-year time period
provided under subsection (c)(4)(A)1., the manufacturer's annual volume of
vehicles produced and delivered for sale in California for a model year is less
than 4500 units and then exceeds 4500 units, the four-year time shall be
restarted beginning with that model year in which the manufacturer exceeded the
4500-unit limit.
3. If the
manufacturer's three-year average has previously exceeded 4500 units, then the
manufacturer is not afforded a four-year time period and must comply with the
fleet average requirements applicable to non-small volume manufacturers, as
specified in subsection (d)(1)(A) or (e)(1)(A), as applicable, beginning with
the following model year after the last of the three consecutive model
years.
(B) If a
manufacturer's average model year California sales fall below 4500 units of new
LDVs, MDVs, and heavy-duty vehicles and engines based on the average number of
vehicles produced and delivered for sale in California for the three previous
consecutive model years, the manufacturer shall be treated as a small volume
manufacturer and shall be subject to the requirements for small volume
manufacturers beginning with the next model year.
(5)
Fuel-flexible, bi-fuel, and
dual-fuel vehicles.
(A) For
fuel-flexible, bi-fuel, and dual-fuel LDVs and MDVs, unless otherwise noted,
compliance with the emission standards of this section is required for both the
gaseous or alcohol fuel the vehicle is designed to use and gasoline or diesel,
as applicable. A manufacturer must demonstrate compliance when certifying the
vehicle for operation on the gaseous or alcohol fuel, as applicable, and on
gasoline or diesel, as applicable.
(B) A manufacturer may measure NMHC in lieu
of NMOG when fuel-flexible, bi-fuel and dual-fuel vehicles are operated on
gasoline, in accordance with the "California 2026 and Subsequent Model Year
Criteria Pollutant Exhaust Emission Standards and Test Procedures for Passenger
Cars, Light-Duty Trucks, and Medium-Duty Vehicles."
(C) For fuel-flexible, bi-fuel, and dual-fuel
vehicles operating on gasoline, a manufacturer may provide an attestation to
demonstrate compliance with 50 degree F standards. Testing at 50 degree F is
required for fuel-flexible, bi-fuel, and dual fuel vehicles when operating on
the alcohol fuel.
(6)
Equivalence with Federal Standards
(A) A manufacturer may not certify a 2026 or
subsequent model year LDV or MDV model to a California emission category in
subsection (d)(2)(A) or (e)(2)(A) that is less stringent than the emission bin
to which the equivalent vehicle model certifies federally. The equivalent
California model may only be certified to a California vehicle emissions
category that is the same or more stringent as the federal emissions bin. The
federal emission bins are those contained in Table 2 of
40 CFR section
86.1811-17(b), as amended
June 29, 2021 and Tables 2 and 3 of
40 CFR section
86.1816-18(b), as amended
October 25, 2016. The criteria for applying this requirement are set forth in
Part I, section H.1.4 of the "California 2026 and Subsequent Model Year
Criteria Pollutant Exhaust Emission Standards and Test Procedures for Passenger
Cars, Light-Duty Trucks, and Medium-Duty Vehicles."
(B)
Exception for Clean Fuel Fleet
Vehicles. Subsection (c)(6)(A) does not apply in the case of a
federally certified vehicle model that is only marketed or primarily marketed
to fleet operators for applications that are subject to clean fuel fleet
requirements established pursuant to section 246 of the federal Clean Air Act
(42 U.S.C. §
7586). For purposes of this subsection,
"primarily offered" shall mean that the model will only be marketed to, and
predominantly sold or leased to, clean fuel fleet operators for such
applications, and that other sales or leases of the model will be incidental
and inconsequential relative to those made to clean fuel fleet
operators.
(7)
Submittal of Information. Unless otherwise specified, reports,
documentation, notices, and requests under this section
1961.4 must be provided to the
California Air Resources Board through the electronic Document Management
System available through the website:
https://arb.ca.gov/certification-document-management-system.
(8)
Attestation. Unless
otherwise specified, where this section allows for or requires a manufacturer
to provide an attestation, attestation means a statement signed and dated by an
individual, who is employed by a manufacturer and authorized to affirm the
attested statement on behalf of the manufacturer, certifying under penalty of
perjury under the laws of the State of California that the attested statement
is true, accurate, and complete.
(d)
Passenger Car, Light-Duty Truck,
and Medium-Duty Passenger Vehicle Standards. The following standards
and requirements for determining compliance with the standards apply to
manufacturers and their LDVs, which are classified under this section as PCs,
LDTs, or MDPVs, that are produced and delivered for sale in California. LDVs

(C)
Small Volume
Manufacturers. All LDVs certified by a small volume manufacturer for
the 2026 and subsequent model years must meet the LEV IV exhaust standards in
this section
1961.4. In lieu of meeting the
fleet average of subsection (d)(1)(A) for the 2026 and subsequent model years,
a small volume manufacturer may certify its LDVs to a fleet average NMOG+NOx
value of 0.051 g/mi calculated in accordance with subsection (d)(1)(B) except
as follows:
1. A small volume manufacturer
may include 100 percent of its ZEVs that are produced and delivered for sale in
California in its fleet average calculation for 2026 and subsequent model
years.
2. A small volume
manufacturer may emission-adjust, by using the PHEV contribution factor of
subsection (d)(1)(B)4., 100 percent of its PHEVs that are produced and
delivered for sale in California in its fleet average calculation for 2026 and
subsequent model years.
(D)
Calculation of NMOG+NOx Credits
and Debits.
1. In 2026 and
subsequent model years, a manufacturer shall calculate its LDV credits or
debits using the following equation.

model year as defined in subsection (d)(1)(A) or (d)(1)(C), as applicable. |
|
FleetAvg
|
= |
Fleet average NMOG+NOx value for the manufacturer for
the applicable model year as calculated per subsection (d)(1)(B). |
|
VehTotalNum
|
= |
Total number of LDVs used in the fleet average
calculation for the model year in accordance with subsection (d)(1)(B)1. or
(d)(1)(B)2., as applicable. |
2.
In 2026 and subsequent model years, a manufacturer that achieves fleet average
NMOG+NOx values lower than the fleet average NMOG+NOx requirement for the
corresponding model year shall earn credits in units of g/mi NMOG+NOx while a
manufacturer with fleet average NMOG+NOx values greater than the fleet average
NMOG+NOx requirement for the corresponding model year shall earn debits in
units of g/mi NMOG+NOx.
3. The
emission credits earned in any given model year shall retain full value through
five subsequent model years after the year in which they were earned. For
example, credits earned in 2027 model year may be used no later than in the
2032 model year.
(E)
Procedure for Offsetting Debits.
1. A manufacturer shall equalize emission
debits by earning g/mi NMOG+NOx emission credits in an amount equal to the g/mi
NMOG+NOx debits or by submitting a commensurate amount of g/mi NMOG+NOx credits
to the Executive Officer that were earned previously or acquired from another
manufacturer. A manufacturer shall equalize NMOG+NOx debits within three model
years. If emission debits are not equalized within the specified time period,
the manufacturer shall be subject to the Health and Safety Code section
43211
civil penalty applicable to a manufacturer that sells a new motor vehicle that
does not meet the applicable emission standards adopted by the state board. The
cause of action shall be deemed to accrue when the emission debits are not
equalized by the end of the specified time period. A manufacturer complying
under Option 2 in subsection (c)(3) must calculate the emission debits that are
subject to a civil penalty under Health and Safety Code section
43211
separately for California and for each individual state using the formulas in
subsections (d)(1)(B)1. and (d)(1)(B)2., except that the number of vehicles in
each test group and the total number of vehicles shall be based on the number
of vehicles produced and delivered for sale in each individual state.
2. For the purposes of Health and Safety Code
section
43211,
the number of LDVs not meeting the state board's emission standards shall be
determined by dividing the total amount of g/mi NMOG+NOx emission debits for
the model year by the g/mi NMOG+NOx fleet average requirement for LDVs
applicable for the model year in which the debits were first
incurred.
3. A manufacturer may be
subject to additional penalties under the Health and Safety Code for any other
violation of this section other than the failure to equalize debits within the
specified time period under this subsection.
(F)
Carry Over of NMOG+NOx Credits

b.
Alternative Phase-in Schedule. A manufacturer may use an
alternative phase-in schedule to comply with the 1 mg/mi particulate standard
as long as the PM emission reductions from LDVs that are achieved using the
alternative phase-in schedule are, by the 2028 model year, equivalent to or
greater than those that are achieved using the phase-in schedules in subsection
(d)(2)(A)2.a. for model years 2026 through 2028 and in title 13, CCR, section
1961.2(a)(2)(A)
for model years 2024 and 2025. For purposes of this section, emission
reductions shall be calculated by multiplying the manufacturer's percent of
total LDVs certified to the 1 mg/mi particulate standard in a given model year
(based on the manufacturer's projected sales volume) by 4 for the 2025 model
year, 3 for the 2026 model year, 2 for the 2027 model year, and 1 for the 2028
model year. The yearly results shall be summed together to determine a
cumulative total. A manufacturer may also include vehicles certified to the 1
mg/mi standard prior to the 2025 model year (i.e., the percent of vehicles
introduced in 2024 or earlier model year would be multiplied by 4) to the
cumulative total. The cumulative total must be (i) equal to or greater than 500
and (ii) 100 percent of the manufacturer's 2028 and subsequent model year LDVs
must be certified to the 1 mg/mi particulate standard for the alternative
schedule to be considered equivalent.
c.
Small Volume
Manufacturers. In lieu of the phase-in of subsection (d)(2)(A)2.a. or
(d)(2)(A)2.b., a small volume manufacturer may certify 100 percent of its LDV
fleet to the 3 mg/mi particulate standard for the 2026 and 2027 model years and
100 percent to the 1 mg/mi standard in the 2028 and subsequent model
years.
3.
Interim
In-Use Compliance Particulate Standards. For test groups that are
first certified to the 1 mg/mi particulate standard in the 2026 through 2028
model years, the interim in-use compliance standard is 2 mg/mi for the first
two model years that the test group is certified to the 1 mg/mi particulate
standard. For example, if a test group that was certified to the 3 mg/mi
particulate standard in the 2027 model year is first certified to the 1 mg/mi
particulate standard in the 2028 model year, the 2 mg/mi particulate interim
in-use compliance standard shall apply to that test group for both the 2028 and
2029 model years.
(B)
Partial Soak Standards
1.
Partial Soak Requirements. For each test group subject to the
exhaust emission standards in subsection (d)(2)(A), a manufacturer shall attest
in the certification application that all vehicles in the test group meet the
following Partial Soak exhaust standards for the full useful life of the
vehicle when operated at low altitude and tested in accordance with the
"California 2026 and Subsequent Model Year Criteria Pollutant Exhaust Emission
Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and

Alternative Phase-in Schedule. A manufacturer may use an
alternative phase-in schedule to comply with the US06 NMOG+NOx and CO emission
standards as long as it satisfies the following three requirements:
(i) the cumulative total calculated for the
alternative phase-in schedule according to the method below must be equal to or
greater than 310 by the end of the 2028 model year,
(ii) 100 percent of the manufacturer's LDVs
must be certified to the US06 NMOG+NOx and CO emission standards in subsection
(d)(3)(A)1. in the 2029 model year and in all subsequent model years,
and
(iii) any 2026 to 2028 model

in subsection (d)(3)(A)1. must be certified to the US06 NMOG+NOx and CO interim
emission standards in subsection (d)(3)(A)2. The total compliance calculation
is determined by multiplying the percent of a manufacturer's total LDVs meeting
the US06 NMOG+NOx and CO standards in subsection (d)(3)(A)1. in a given model
year (based on a manufacturer's projected sales) by 4 for the 2025 model year,
3 for the 2026 model year, 2 for the 2027 model year, and 1 for the 2028 model
year. The yearly results shall be summed together to determine a cumulative
total. A manufacturer may not include 2024 and earlier model year LDVs in the
calculation.
c.
Small Volume Manufacturers. In lieu of the phase-in of
subsection (d)(3)(A)3.a. or (d)(3)(A)3.b., a small volume manufacturer may
certify 100 percent of its LDV fleet to the interim US06 NMOG+NOx and CO
standards in subsection (d)(3)(A)2. in the 2026 through 2029 model years and
100 percent of its fleet to the US06 NMOG+NOx and CO standards in subsection

(ii) 100 percent of the manufacturer's LDV
PHEVs must be certified to the High Power Cold Start US06 standards in the 2029
model year and in all subsequent model years. The total compliance calculation
for the alternative phase-in is determined by multiplying the percent of a
manufacturer's total number of LDV test groups with PHEVs certified to the High
Power Cold Start US06 standards in a given model year by 3 for the 2026 model
year, 2 for the 2027 model year, and 1 for the 2028 model year. The yearly
results shall be summed together to determine a cumulative total. A
manufacturer may not include 2025 and earlier model year LDV PHEV test groups
in the calculation.
c.

through (e)(1)(H) do not apply to a small volume manufacturer that certifies
its MDV test groups to this subsection (e)(1)(D).
(E)
Calculation of NMOG+NOx Credits
and Debits.
1. In 2026 and
subsequent model years, a manufacturer shall calculate its credits or debits
separately for MDVs 8,501 to 10,000 lbs. GVWR and for MDVs 10,001 to 14,000
lbs. GVWR using the following equation.
Credits(or Debits) =
(FleetAvgReq-FleetAvg) x
VehTotalNum
Where:
|
Credits (or Debits)
|
= |
Credits or debits earned, in g/mi, rounded to the
nearest 0.001 g/mi. |
|
FleetAvgReq
|
= |
Fleet average NMOG+NOx requirement for the applicable
model year and MDV GVWR classification as defined in subsection (e)(1)(A). |
|
FleetAvg
|
= |
Fleet average NMOG+NOx value for the manufacturer for
the applicable MDV GVWR classification calculated per subsection
(e)(1)(B). |
|
VehTotalNum
|
= |
Total number of MDVs in the applicable MDV GVWR
classification used in the fleet average calculation for the model year in
accordance with subsection (e)(1)(B) as applicable. |
2.
In 2026 and subsequent model years, a manufacturer that achieves fleet average
NMOG+NOx values lower than the fleet average NMOG+NOx requirement for the
corresponding model year shall earn credits in units of g/mi NMOG+NOx while a
manufacturer with 2026 and subsequent model year fleet average NMOG+NOx values
greater than the fleet average requirement for the corresponding model year
shall earn debits in units of g/mi NMOG+NOx. The total g/mi NMOG+NOx credits or
debits earned for MDVs 8,501 to 10,000 lbs. GVWR and for MDVs 10,001 to 14,000
lbs. GVWR shall be separately tracked and reported each model year. MDV fleet
average credits earned in either MDV GVWR category may be used to offset debits
in either MDV GVWR category. MDV fleet average credits and debits earned in
accordance with subsection (e)(1) may not be combined or otherwise used with
LDV fleet average credits and debits earned in accordance with subsection
(d)(1).
3. The emission credits
earned in any given model year shall retain full value through five subsequent
model years after the year in which they were earned. For example, credits
earned in 2027 model year may be used no later than in the 2032 model
year.
(F)
Procedure for Offsetting Debits.
1. A manufacturer shall equalize emission
debits by earning g/mi NMOG+NOx emission credits in an amount equal to the g/mi
NMOG+NOx debits or by submitting a commensurate amount of g/mi NMOG+NOx credits
to the Executive Officer that were earned previously or acquired from another
manufacturer. A manufacturer may not carry forward debits to a subsequent model
year unless the manufacturer has used all eligible credits from both MDV GVWR
categories. A manufacturer shall equalize NMOG+NOx debits within three model
years after the model year in which they were earned. If emission debits are
not equalized within the specified time period, the manufacturer shall be
subject to the Health and Safety Code section
43211
civil penalty applicable to a manufacturer that sells a new motor vehicle that
does not meet the applicable emission standards adopted by the state board. The
cause of action shall be deemed to accrue when the emission debits are not
equalized by the end of the specified time period. A manufacturer complying
under Option 2 in subsection (c)(3) must calculate the emission debits that are
subject to a civil penalty under Health and Safety Code section
43211
separately for California and for each individual state using the formulas in
subsections (e)(1)(B)1. and (e)(1)(B)2., except that the number of vehicles in
each test group and the total number of vehicles shall be based on the number
of vehicles produced and delivered for sale in each individual state.
2. For the purposes of Health and Safety Code
section
43211,
the number of MDVs not meeting the state board's emission standards shall be
determined by dividing the total amount of g/mi NMOG+NOx emission debits for
the model year by the g/mi NMOG+NOx fleet average requirement applicable to
that MDV GVWR category for the model year in which the debits were first
incurred.
3. A manufacturer may be
subject to additional penalties under the Health and Safety Code for any other
violation of this section other than the failure to equalize debits within the
specified time period under this subsection.
(G)
Carry Over of NMOG+NOx Credits
and Debits from LEV III to LEV IV. Any LEV III MDV NMOG+NOx fleet
average emission credits that have not been used prior to the start of the 2026
model year shall retain their original value and expiration as earned under
title 13, CCR, section
1961.2 and are available for use
or trade by the manufacturer under this section
1961.4. Any LEV III MDV NMOG+NOx
fleet average debits that have not been offset prior to the start of 2026 model
year shall retain their original value and deadline to be offset as earned
under title 13, CCR, section
1961.2 and must be offset by
credits earned or acquired by the manufacturer under this section
1961.4.
(H)
Converting Vehicle-Equivalent
Credits and Debits to NMOG+NOx Fleet Average Credits and Debits. Any
vehicle-equivalent credits (VEC) and debits earned in accordance with title 13,
CCR, section
1961.2(c)(2)(A)
that have not been used or offset prior to the start of the 2026 model year
shall be converted to NMOG+NOx fleet average credits and debits as follows:
1. The manufacturer shall use the calculation
in subsection (e)(1)(E) separately for each model year and MDV GVWR category in
which the unused VECs or not yet offset debits were originally earned to
calculate the corresponding NMOG+NOx fleet average credits or debits that the
manufacturer's fleet would have earned.
2. For the purpose of applying the formula in
subsection (e)(1)(E)1., the fleet average NMOG+NOx requirement is the fleet
average in title 13, CCR, section
1961.2(b)(3)(C)1.a.,
applicable to the MDV GVWR category and model year.
3. For any model year in which a different
amount than the originally earned VECs or debits remain at the start of the
2026 model year (e.g., due to usage or trades), the converted NMOG+NOx fleet
average credits or debits calculated per subsection (e)(1)(H)1. shall be scaled
by the same percentage relative to the original earned quantity. For example,
if 200 VECs were originally earned for 2024 model year but only 50 of those
VECs remain at the start of the 2026 model year, the converted NMOG+NOx credits
calculated for 2024 model year shall be reduced by 75 percent.
4. Converted NMOG+NOx fleet average credits
and debits retain the same expiration and deadline to offset as the
corresponding VECs and debits earned under title 13, CCR, section
1961.2 based on the model year in
which they were originally earned as VECs or
debits.

1 Power to Weight Ratio. If all vehicles
in a test group have a power to weight ratio at or below a threshold of 0.024,
the manufacturer may use the US06 Bag 2 test cycle and standard in lieu of the
full US06 cycle and standard. The cutoff is determined by using a ratio of the
engine's maximum rated horsepower, as established by the manufacturer in the
vehicle's certification application, to the vehicle's GVWR in pounds and does
not include any horsepower contributed by electric motors in the case of hybrid
electric vehicles or PHEVs. Manufacturers may use the full US06 cycle and
standard regardless of the calculated ratio; in such case, manufacturers shall
meet the standards applicable to vehicles with power-to-weight ratios greater
than 0.024.
2 Road Speed Fan. Manufacturers may use a
road speed modulated fan as specified in
40 CFR section
1066.105, as applicable, instead of a fixed
speed fan for MDV SFTP testing.

in the 2026 through 2029 model years and 100 percent of its fleet to the SFTP
PM standards in subsection (e)(3)(A)1. in 2030 and subsequent model
years.
(4)
SC03 Standards. The
maximum SC03 NMOG+NOx and CO exhaust emissions for the full useful life of 2026
and subsequent model year MDVs must not be greater than the applicable LEV IV
NMOG+NOx and CO emission standards set forth in subsection (e)(2)(A). For each
test group, a manufacturer must submit with the certification application an
attestation that NMOG+NOx and CO exhaust emissions for vehicles tested using
the SC03 test procedures incorporated in the "California 2026 and Subsequent
Model Year Criteria Pollutant Exhaust Emission Standards and Test Procedures
for Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles" comply with
the applicable SC03 standards.
(5)
Highway Standards. The maximum emissions of NMOG+NOx measured
on the federal Highway Fuel Economy Test (HWFET;
40 CFR section
1066.840), as modified by the "California
2026 and Subsequent Model Year Criteria Pollutant Exhaust Emission Standards
and Test Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty
Vehicles," may not be greater than the applicable LEV IV NMOG+NOx standard set
forth in subsection (e)(2)(A).
(6)

(f)
Additional Provisions
(1)
Generate Additional NMOG+NOx Fleet Average Credit. For a
vehicle that is certified to the LEV IV standards in subsection (d)(2)(A) that
does not earn ZEV vehicle values under title 13, CCR, section
1962.4, a manufacturer may
subtract 5 mg/mi from the NMOG+NOx emission standards value set forth in
subsection (d)(1)(B)3. when calculating the manufacturer's fleet average,
provided that the manufacturer extends the emissions performance and defects
warranty period to 15 years or 150,000 miles, whichever occurs first, except
that the time period is to be 10 years for a zero-emission energy storage
device (such as battery, ultracapacitor, or other electric storage
device).
(2)
NMOG Credit
for Direct Ozone Reduction Technology. A manufacturer that certifies
vehicles equipped with direct ozone reduction technologies shall be eligible to
earn NMOG credits in accordance with CCR,
title 13, section
1961.2(a)(11),
which will be applied to the NMOG exhaust emissions of the vehicle when
determining compliance with the LEV IV FTP standard in subsection (d)(2)(A) or
(e)(2)(A).
(3)
Emission
Standard for a Fuel-Fired Heater. Whenever a manufacturer elects to
utilize an on-board fuel-fired heater on any LDV or MDV, the fuel-fired heater
must meet the LDV ULEV125 standards set forth in subsection (d)(2)(A). The
exhaust emissions result of the fuel-fired heater shall be determined by
operating at a maximum heating capacity with a cold start between 68 degrees F
and 86 degrees F for a period of 20 minutes and dividing the grams of emissions
by 20. The resulting grams per minute shall be multiplied by 3.0 minutes per
mile to obtain a g/mi value that must be below the ULEV125 standards. If the
on-board fuel-fired heater is capable of operating at ambient temperatures
above 40 degrees F, the measured emission levels of the on-board fuel-fired
heater shall be added to the emissions measured on the FTP ( 40 CFR, Part
1066), as amended by the "California 2026 and Subsequent Model Year Criteria
Pollutant Exhaust Emission Standards and Test Procedures for Passenger Cars,
Light-Duty Trucks, and Medium-Duty Vehicles" or as amended by the "California
Test Procedures for 2026 and Subsequent Model Year Zero-Emission Vehicles and
Plug-in Hybrid Electric Vehicles, in the Passenger Car, Light-Duty Truck and
Medium-Duty Vehicle Classes," as applicable, to determine compliance with the
exhaust emission standards in subsection (d)(2)(A) or
(e)(2)(A).
(g)
Disclosure of Records.
(1)
Public Disclosure. Unless identified as a trade secret or
otherwise confidential under CCR, title 17, section
91011, and supported as
such under CCR, title 17, section
91022, records in the Board's possession for
the vehicles subject to the requirements of section
1961.4, such as the following, are
subject to disclosure as public records:
(A)
