California Code of Regulations › Title 13 - Motor Vehicles › Division 3 - Air Resources Board › Chapter 1 - Motor Vehicle Pollution Control Devices › Article 2 - Approval of Motor Vehicle Pollution Control Devices (New Vehicles) › Section 1961.2 - Exhaust Emission Standards and Test Procedures-2015 Through 2025 Model Year Passenger Cars and Light-Duty Trucks, and 2015 Through 2028 Model Year Medium-Duty Vehicles

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
This section
					 1961.2 contains the California
					 "LEV III" exhaust emission standards for 2015 through 2025 model year passenger
					 cars and light-duty trucks, and 2015 through 2028 model year medium-duty
					 vehicles. A manufacturer must demonstrate compliance with the exhaust standards
					 in subsection (a) applicable to specific test groups, and with the composite
					 phase-in requirements in subsection (b) applicable to the manufacturer's entire
					 fleet. The exhaust standards in subsection (a) do not apply to ZEVs. ZEVs are
					 subject to the phase-in requirements in subsection (b) as noted.
Before the 2015 model year, a manufacturer that produces
					 vehicles that meet the standards in subsection (a) has the option of certifying
					 the vehicles to those standards, in which case the vehicles will be treated as
					 LEV III vehicles for purposes of the fleet-wide phase-in requirements.
					 Similarly, 2015-2019 model-year vehicles may be certified to the "LEV II"
					 exhaust emission standards in subsection
					 1961(a)(1), in
					 which case the vehicles will be treated as LEV II vehicles for purposes of the
					 fleet-wide phase-in requirements.
A manufacturer has the option of certifying engines used in
					 incomplete and diesel medium-duty vehicles with a gross vehicle weight rating
					 of greater than 10,000 lbs. GVW to the heavy-duty engine standards and test
					 procedures set forth in title 13, CCR, subsections
					 1956.8. In 2020 and subsequent
					 model years, all medium-duty vehicles with a gross vehicle weight rating of
					 less than or equal to 10,000 lbs. GVW, including incomplete otto-cycle
					 medium-duty vehicles and medium-duty vehicles that use diesel cycle engines,
					 must be certified to the LEV III chassis standards and test procedures set
					 forth in this section
					 1961.2 or to the LEV IV chassis
					 standards and test procedures set forth in section
					 1961.4.
Pooling Provision.
For each model year, a manufacturer must demonstrate
					 compliance with this section
					 1961.2 based on one of two options
					 applicable throughout the model year, either:
Option 1: the total number of passenger cars, light-duty
					 trucks, and medium-duty vehicles that are certified to the California exhaust
					 emission standards in subsection (a) and subsection
					 1961(a)(1), and
					 are produced and delivered for sale in California; or
Option 2: the total number of passenger cars, light-duty
					 trucks, and medium-duty vehicles that are certified to the California exhaust
					 emission standards in subsection (a) and subsection
					 1961(a)(1), and
					 are produced and delivered for sale in California and any states or the
					 District of Columbia that have adopted California's criteria pollutant emission
					 standards set forth in this section
					 1961.2 for that model year
					 pursuant to section
					 177 of the federal Clean Air Act
					 (42 U.S.C. §
											7507).
A manufacturer that selects compliance Option 2 must notify
					 the Executive Officer of that selection in writing prior to the start of the
					 applicable model year or must comply with Option 1. Once a manufacturer has
					 selected compliance Option 2, that selection applies unless the manufacturer
					 selects Option 1 and notifies the Executive Officer of that selection in
					 writing before the start of the applicable model year.
When a manufacturer is demonstrating compliance using
					 Option 2 for a given model year, the term "in California" as used in this
					 section 1961.2 means California and any
					 states or the District of Columbia that have adopted California's criteria
					 pollutant emission standards set forth in this section
					 1961.2 for that model year
					 pursuant to Section
					 177 of the federal Clean Air Act
					 (42 U.S.C. §
											7507).

				  allowance in accordance with the "California Exhaust Emission Standards and
				  Test Procedures for 2009 through 2017 Model Zero-Emission Vehicles and Hybrid
				  Electric Vehicles, in the Passenger Car, Light-Duty Truck and Medium-Duty
				  Vehicle Classes" and 2015--2016 model year vehicles that are allowed to certify
				  to LEV II SULEV standards using "carryover" of emission test data under the
				  provisions in subsection (b)(2) may be certified to the 150,000 mile NMOG+NOx
				  emission standards for SULEV30, SULEV170, or SULEV230, as applicable, in this
				  subsection (a)(1) and the corresponding NMOG+NOx numerical values in subsection
				  (a)(4), in lieu of the separate NMOG and NOx exhaust emission standards in
				  subsection
				  1961(a)(1) and
				  the corresponding NMOG numerical values in subsection
				  1961(a)(4). LEV
				  II SULEV vehicles that do not either (1) receive a partial ZEV allowance or (2)
				  certify to LEV II SULEV standards in the 2015--2016 model years using
				  "carryover" of emission test data may not certify to combined NMOG+NOx
				  standards. LEV II vehicles that certify to combined NMOG+NOx standards will be
				  treated as LEV II vehicles for purposes of the fleet-wide phase-in
				  requirements.

Alternative
				  Phase-in Schedule for Particulate Standards.
1.
Alternative Phase-in Schedules for
				  the 3 mg/mi Particulate Standard for Passenger Cars, Light-Duty Trucks, and
				  Medium-Duty Passenger Vehicles.
A manufacturer may use an alternative
				  phase-in schedule to comply with the 3 mg/mi particulate standard phase-in
				  requirements as long as:
(1) the percent of
				  PC+LDT+MDPV vehicles meeting the 3 mg/mi particulate standard in the 2019 model
				  year is greater than or equal to the highest percent of PC+LDT+MDPV vehicles
				  meeting the 3 mg/mi particulate standard in the 2016, 2017, and 2018 model
				  years individually;
(2) the percent
				  of PC+LDT+MDPV vehicles meeting the 3 mg/mi particulate standard in the 2020
				  model year is greater than or equal to the highest percent of PC+LDT+MDPV
				  vehicles meeting the 3 mg/mi particulate standard in the 2016, 2017, and 2018
				  model years individually; and
(3)
				  equivalent PM emission reductions are achieved by the 2021 model year from
				  passenger cars, light-duty trucks, and medium-duty passenger vehicles. Model
				  year emission reductions shall be calculated by multiplying the percent of
				  PC+LDT+MDPV vehicles meeting the 3 mg/mi particulate standard in a given model
				  year (based on a manufacturer's projected sales volume of vehicles in each
				  category) by 5 for the 2017 model year, 4 for the 2018 model year, 3 for the
				  2019 model year, 2 for the 2020 model year, and 1 for the 2021 model year. The
				  yearly results for PC+LDT+MDPV vehicles shall be summed together to determine a
				  cumulative total for PC+LDT+MDPV vehicles. In the 2021 model year, the
				  cumulative total must be equal to or greater than 490, and 100 percent of the
				  manufacturer's passenger cars, light-duty trucks, and medium-duty passenger
				  vehicles must be certified to the 3 mg/mi particulate standard, to be
				  considered equivalent. A manufacturer may add vehicles introduced before the
				  2017 model year (e.g., the percent of vehicles introduced in 2016 would be
				  multiplied by 5) to the cumulative total.
2.
Alternative Phase-in Schedules for
				  the 1 mg/mi Particulate Standard for Passenger Cars, Light-Duty Trucks, and
				  Medium-Duty Passenger Vehicles
. A manufacturer may use an alternative
				  phase-in schedule to comply with the 1 mg/mi particulate standard phase-in
				  requirements as long as the PM emission reductions that are achieved using the
				  alternative phase-in schedule are equivalent to or greater than those that are
				  achieved using the phase-in schedules in subsection (a)(2)(A) for model years
				  2024-2025 and section
				  1961.4
				  (d)(2)(A)2.a. for model years 2026-2028 by
				  the 2028 model year from passenger cars, light-duty trucks, and medium-duty
				  passenger vehicles. Model year emission reductions shall be calculated by
				  multiplying the percent of PC+LDT+MDPV vehicles meeting the 1 mg/mi particulate
				  standard in a given model year (based on a manufacturer's projected sales
				  volume of vehicles in each category) 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 for PC+LDT+MDPV vehicles shall be summed together to determine a
				  cumulative total for PC+LDT+MDPV vehicles. A manufacturer may add vehicles
				  introduced before the 2025 model year (e.g., the percent of vehicles introduced
				  in 2024 or earlier model year would be multiplied by 4) to the cumulative
				  total. In the 2028 model year, the cumulative total must be equal to or greater
				  than 500, and 100 percent of the manufacturer's passenger cars, light-duty
				  trucks, and medium-duty passenger vehicles must be certified to the 1 mg/mi
				  particulate standard, to be considered equivalent.
3.
Alternative Phase-in Schedules for
				  the Particulate Standards for Medium-Duty Vehicles Other than Medium-Duty
				  Passenger Vehicles.
A manufacturer may use an alternative phase-in
				  schedule to comply with the particulate standard phase-in requirements as long
				  as equivalent PM emission reductions are achieved by the 2021 model year from
				  medium-duty vehicles other than medium-duty passenger vehicles. Model year
				  emission reductions shall be calculated by multiplying the total percent of
				  MDVs certified to the 8 mg/mi PM standard or to the 10 mg/mi PM standard, as
				  applicable, in a given model year (based on a manufacturer's projected sales
				  volume of vehicles in each category) by 5 for the 2017 model year, 4 for the
				  2018 model year, 3 for the 2019 model year, 2 for the 2020 model year, and 1
				  for the 2021 model year. The yearly results for MDVs shall be summed together
				  to determine a cumulative total for MDVs. In the 2021 model year, the
				  cumulative total must be equal to or greater than 490, and 100 percent of the
				  manufacturer's MDVs must be certified to the 8 mg/mi PM standard or to the 10
				  mg/mi PM standard, as applicable, to be considered equivalent. A manufacturer
				  may add vehicles introduced before the 2017 model year (e.g., the percent of
				  vehicles introduced in 2016 would be multiplied by 5) to the cumulative
				  total.
(3)
NMOG+NOx Standards for Bi-Fuel, Fuel-Flexible, and Dual-Fuel
				  Vehicles.
For fuel-flexible, bi-fuel, and dual-fuel PCs, LDTs, and
					 MDVs, compliance with the NMOG+NOx exhaust mass emission standards must be
					 based on exhaust emission tests both when the vehicle is operated on the
					 gaseous or alcohol fuel it is designed to use, and when the vehicle is operated
					 on gasoline. A manufacturer must demonstrate compliance with the applicable
					 exhaust mass emission standards for NMOG+NOx, CO, and formaldehyde set forth in
					 the table in subsection (a)(1) when certifying the vehicle for operation on the
					 gaseous or alcohol fuel, as applicable, and on gasoline or diesel, as
					 applicable.
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 2015 through 2025 Model Year Criteria Pollutant
					 Exhaust Emission Standards and Test Procedures and 2017 and Subsequent Model
					 Year Greenhouse Gas Exhaust Emission Standards and Test Procedures for
					 Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles." Testing at
					 50°F is not required for fuel-flexible, bi-fuel, and dual-fuel vehicles
					 when operating on gasoline.
(4)
50°F Exhaust Emission
				  Standards.
All passenger cars, light-duty trucks, and medium-duty
					 vehicles, other than natural gas and diesel-fueled vehicles, must demonstrate
					 compliance with the following 4,000-mile exhaust emission standards for
					 NMOG+NOx and formaldehyde (HCHO) measured on the FTP ( 40 CFR, Part 86 ,
					 Subpart B) conducted at a nominal test temperature of 50°F, as modified by
					 Part II, Section D of the "California 2015 through 2025 Model Year Criteria
					 Pollutant Exhaust Emission Standards and Test Procedures and 2017 and
					 Subsequent Model Year Greenhouse Gas Exhaust Emission Standards and Test
					 Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles." A
					 manufacturer may demonstrate compliance with the NMOG+NOx and HCHO
					 certification standards contained in this subparagraph by measuring NMHC
					 exhaust emissions or issuing a statement of compliance for HCHO in accordance
					 with Section D.1.10 and Section G.3.1.2, respectively, of the "California 2015
					 through 2025 Model Year Criteria Pollutant Exhaust Emission Standards and Test
					 Procedures and 2017 and Subsequent Model Year Greenhouse Gas Exhaust Emission
					 Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and
					 Medium-Duty Vehicles." Emissions of CO measured at 50°F at 4,000 miles
					 shall not exceed the standards set forth in subsection (a)(1) applicable to
					 vehicles of the same emission category and vehicle type subject to a cold soak
					 and emission test at 68° to 86° F.

Supplemental Federal Test
				  Procedure (SFTP) Off-Cycle Emission Standards.
(A)
SFTP NMOG+NOx and CO Exhaust
				  Emission Standards for Passenger Cars, Light-Duty Trucks, and Medium-Duty
				  Passenger Vehicles.
Manufacturers shall certify 2015 through 2025
				  model year LEVs, ULEVs, and SULEVs in the PC, LDT, and MDPV classes to either
				  the
SFTP NMOG+NOx and CO Stand-Alone Exhaust Emission
				  Standards
set forth in subsection (a)(7)(A)1, or in accordance with
				  the
SFTP NMOG+NOx and CO Composite Exhaust Emission Standards and
				  Fleet-Average Requirements
set forth in subsection (a)(7)(A)2. A
				  manufacturer may also certify 2014 model LEVs, ULEVs, or SULEVs in the PC, LDT,
				  or MDPV classes to LEV III SFTP standards, in which case, the manufacturer
				  shall be subject to the LEV III SFTP emission standards and requirements,
				  including the sales-weighted fleet-average NMOG+NOx composite emission standard
				  applicable to 2015 model vehicles if choosing to comply with the
SFTP
				  NMOG+NOx and CO Composite Exhaust Emission Standards and Fleet-Average
				  Requirements
set forth in subsection (a)(7)(A)2. The manufacturer
				  shall notify the Executive Officer of its selected emission standard type in
				  the Application for Certification of the first test group certifying to SFTP
				  NMOG+NOx and CO emission standards on a 150,000 mile durability basis. Once an
				  emission standard type for NMOG+NOx and CO is selected for a fleet, and the
				  Executive Officer is notified of such selection, the selection must be kept
				  through the 2025 model year for the entire fleet, which includes LEV II
				  vehicles if selecting to comply with subsection (a)(7)(A)2. The manufacturer
				  may not change its selection until the 2026 model year. Test groups not
				  certifying to the 150,000-mile SFTP NMOG+NOx and CO emission standards pursuant
				  to this subsection (a)(7)(A) shall be subject to the 4,000-mile SFTP NMOG+NOx
				  and CO emission standards set forth in subsection
				  1960.1(r).
1.
SFTP NMOG+NOx and CO Exhaust
				  Stand-Alone Emission Standards
. The following standards are the
				  maximum SFTP NMOG+NOx and CO exhaust emissions through full useful life from
				  2015 through 2025 model-year LEV III LEVs, ULEVs, and SULEVs when operating on
				  the same gaseous or liquid fuel they use for FTP certification. These standards
				  only apply to 2015 through 2016 model year fuel-flexible vehicles [LESS THAN
				  EQUAL TO] 6,000 lbs. GVWR and 2015 through 2017 model year fuel-flexible
				  vehicles > 6,000 lbs. GVWR when operating on the LEV III certification
				  gasoline specified in Part II, Section A.100.3.1.2 of the "California 2015
				  through 2025 Model Year Criteria Pollutant Exhaust Emission Standards and Test
				  Procedures and 2017 and Subsequent Model Year Greenhouse Gas Exhaust Emission
				  Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and
				  Medium-Duty Vehicles." 2017 through 2025 model year multi-fueled vehicles
				  (including bi-fueled, dual-fueled and fuel-flexible vehicles) [LESS THAN EQUAL
				  TO] 6,000 lbs. GVWR as well as 2018 through 2025 model year multi-fueled
				  vehicles > 6,000 lbs. GVWR, including vehicles certifying with carryover
				  data, shall comply with all requirements established for each consumed fuel (or
				  blend of fuels in the case of fuel-flexible vehicles).

Manufacturers
					 must certify all vehicles, which are certifying to a LEV III FTP emission
					 category on a 150,000-mile durability basis, to the emission standards of the
					 equivalent, or a more stringent, SFTP emission category set forth on this
					 table. That is, all LEV III LEVs certified to 150,000-mile FTP emission
					 standards shall comply with the SFTP LEV emission standards in this table, all
					 LEV III ULEVs certified to 150,000-mile FTP emission standards shall comply
					 with the SFTP ULEV emission standards in this table, and all LEV III SULEVs
					 certified to 150,000-mile FTP emission standards shall comply with the SFTP
					 SULEV emission standards in this table.
2
Optional SFTP SULEV Standards.
A
					 manufacturer may certify light-duty truck test groups from 6,001 to 8,500 lbs.
					 GVWR and MDPV test groups to the SULEV, option A, emission standards set forth
					 in this table for the 2015 through 2020 model year, only if the vehicles in the
					 test group are equipped with a particulate filter and the manufacturer extends
					 the particulate filter emission warranty mileage to 200,000 miles. Passenger
					 cars and light-duty trucks 0-6,000 lbs. GVWR are not eligible for this
					 option.
2.
SFTP
				  NMOG+NOx and CO Composite Exhaust Emission Standards
. For the 2015
				  through 2025 model years, a manufacturer selecting this option must certify LEV
				  II and LEV III LEVs, ULEVs, and SULEVs, such that the manufacturer's
				  sales-weighted fleet-average NMOG+NOx composite emission value does not exceed
				  the applicable NMOG+NOx composite emission standard set forth in the following
				  table. In addition, the CO composite emission value of any LEV III test group
				  shall not exceed the CO composite emission standard set forth in the following
				  table. SFTP compliance shall be demonstrated using the same gaseous or liquid
				  fuel used for FTP certification. These standards only apply to 2015 through
				  2016 model year fuel-flexible vehicles [LESS THAN EQUAL TO] 6,000 lbs. GVWR and
				  2015 through 2017 model year fuel-flexible vehicles > 6,000 lbs. GVWR when
				  operating on the LEV III certification gasoline specified in Part II, Section
				  A.100.3.1.2 of the "California 2015 through 2025 Model Year Criteria Pollutant
				  Exhaust Emission Standards and Test Procedures and 2017 and Subsequent Model
				  Year Greenhouse Gas Exhaust Emission Standards and Test Procedures for
				  Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles." 2017 through 2025
				  model year multi-fueled vehicles (including bi-fueled, dual-fueled and
				  fuel-flexible vehicles) [LESS THAN EQUAL TO] 6,000 lbs. GVWR as well as 2018
				  through 2025 model year multi-fueled vehicles > 6,000 lbs. GVWR, including
				  vehicles certifying with carryover data, shall comply with all requirements
				  established for each consumed fuel (or blend of fuels in the case of
				  fuel-flexible vehicles).
For each test group subject to this subsection,
					 manufacturers shall calculate a Composite Emission Value for NMOG+NOx and, for
					 LEV III test groups, a separate Composite Emission Value for CO, using the
					 following equation:
Composite Emission Value =
0.28 x US06 + 0.37 x SC03 + 0.35 x FTP [Eq. 1]
where
"US06" = the test group's NMOG+NOx or CO emission value, as
					 applicable, determined through the US06 test;
"SC03" = the test group's NMOG+NOx or CO emission value, as
					 applicable, determined through the SC03 test; and
"FTP" = the test group's NMOG+NOx or CO emission value, as
					 applicable, determined through the FTP test.
If no vehicles in a test group have air conditioning units,
					 the FTP cycle emission value can be used in place of the SC03 cycle emission
					 value in Equation 1. To determine compliance with the SFTP NMOG+NOx composite
					 emission standard applicable to the model year, manufacturers shall use a
					 sales-weighted fleet average of the NMOG+NOx composite emission values of every
					 applicable test group. The sales-weighted fleet average shall be calculated
					 using a combination of carry-over and new certification SFTP composite emission
					 values (converted to NMOG+NOx, as applicable). LEV II test groups will use
					 their emission values in the fleet average calculation but will not be
					 considered LEV III test groups. Compliance with the CO composite emission
					 standard cannot be demonstrated through fleet averaging. The NMOG+NOx
					 sales-weighted fleet-average composite emission value for the fleet and the CO
					 composite emission value for each test group shall not exceed:

All test groups
					 certifying to LEV III FTP emission standards on a 150,000-mile durability basis
					 shall also certify to the SFTP on a 150,000-mile durability basis, as tested in
					 accordance with the "California 2015 through 2025 Model Year Criteria Pollutant
					 Exhaust Emission Standards and Test Procedures and 2017 and Subsequent Model
					 Year Greenhouse Gas Exhaust Emission Standards and Test Procedures for
					 Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles."
2
Determining NMOG+NOx Composite Emission Values of
					 LEV II Test Groups and Cleaner Federal Vehicles.
For test groups
					 certified to LEV II FTP emission standards, SFTP emission values shall be
					 converted to NMOG+NOx and projected out to the same full useful life mileage as
					 their LEV II FTP certification, 120,000 miles or 150,000 miles using
					 deterioration factors or aged components. In lieu of deriving a deterioration
					 factor specific to SFTP test cycles, carry-over LEV II test groups may use the
					 applicable deterioration factor from the FTP cycle in order to determine the
					 carry-over composite emission values for the purpose of the NMOG+NOx
					 sales-weighted fleet-average calculation. If an SFTP full-useful life emission
					 value is used to comply with the LEV II SFTP 4k standards, that value may be
					 used in the sales-weighted fleet-average without applying an additional
					 deterioration factor. For federally-certified test groups certifying in
					 California in accordance with Section H.1.4 of the "California 2015 through
					 2025 Model Year Criteria Pollutant Exhaust Emission Standards and Test
					 Procedures and 2017 and Subsequent Model Year Greenhouse Gas Exhaust Emission
					 Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and
					 Medium-Duty Vehicles," the full-useful life emission value used to comply with
					 federal full-useful life SFTP requirements may be used in the sales-weighted
					 fleet-average without applying an additional deterioration factor. For
					 gasoline-fueled vehicles, NMHC emission values for the US06 and SC03 test
					 cycles shall be converted to NMOG emission values by multiplying by a factor of
					 1.03. LEV II test groups that contain vehicles at or below 6,000 lbs. GVWR
					 shall certify to SFTP bins as described in footnote 4 at the same full useful
					 life mileage as their LEV II FTP certification starting model year 2017 and in
					 each subsequent model year, thereafter. LEV II test groups that only contain
					 vehicles above 6,000 lbs. GVWR shall certify to SFTP bins as described in
					 footnote 4 at the same full useful life mileage as their LEV II FTP
					 certification starting model year 2018 and in each subsequent model year,
					 thereafter. Test groups certifying to bins shall be subject to the in-use
					 requirements in section (a)(8)(c).
3 MDPVs are excluded from SFTP NMOG+NOx and CO emission
					 standards and the sales-weighted fleet average until they are certified to LEV
					 III FTP 150,000-mile NMOG+NOx and CO requirements.
4 LEV II test groups shall certify to bins in increments of
					 0.010 g/mi. Beginning with the 2018 model year, vehicles may not certify to bin
					 values above a maximum of 0.180 g/mi.
5
Calculating the sales-weighted average for
					 NMOG+NOx.
For each model year, the manufacturer shall calculate and
					 report to the Executive Officer, its sales-weighted fleet-average NMOG+NOx
					 composite emission value as follows.
Click
					 here to view image
where "n" = a manufacturer's total number of PC,
								LDT, and, if applicable, MDPV certification bins, in a given model year
								including carry-over certification bins, certifying to SFTP composite emission
								standards in that model year;
"number of vehicles in the test group" = the number
								of vehicles produced and delivered for sale in California in the certification
								test group; and
"Composite Value of Bin" = the numerical value
								selected by the manufacturer for the certification bin that serves as the
								emission standard for the vehicles in the test group with respect to all
								testing for test groups certifying to SFTP on a 150,000-mile durability basis,
								and the SFTP carry-over composite emission value, as described in footnote 2 of
								this table, for carry-over LEV II test groups. For each test group, the
								manufacturer shall report to the Executive Officer the composite value of bin
								and the number of vehicles within the test group.
6
Calculation of
								Fleet Average Total NMOG+NOx Credits or Debits.
A manufacturer shall
								calculate the total NMOG+NOx credits or debits, as follows:
[(NMOG+NOx Composite Emission Standard) --
								(Manufacturer's Sales-Weighted Fleet-Average Composite Emission Value)] x
								(Total Number of Vehicles Produced and Delivered for Sale in California in the
								0-8,500 lbs GVWR plus MDPVs classes, if applicable) [Eq. 3]
A negative number constitutes total NMOG+NOx
								debits, and a positive number constitutes total NMOG+NOx credits accrued by the
								manufacturer for the given model year. Total NMOG+NOx credits earned in a given
								model year retain full value through the fifth model year after they are
								earned. At the beginning of the sixth model year, the total NMOG+NOx credits
								have no value. A manufacturer may trade credits with other manufacturers A
								manuafacturer shall equalize total NMOG+NOx debits within three model years
								after they have been incurred by earning NMOG+NOx credits in an amount equal to
								the total NMOG+NOx debits. If total NMOG+NOx debits are not equalized within
								the three model-year period, the manufacturer is subject to the Health and
								Safety Code section
								43211
								civil penalty applicable to a manufacturer which 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 total NMOG+NOx debits are
								not equalized by the end of the specified time period. For the purposes of
								Health and Safety Code section
								43211,
								the number of vehicles not meeting the state board's emission standards is
								determined by dividing the NMOG+NOx debits for the model year by the NMOG+NOx
								composite emission standard in effect during the model year in which the debits
								were incurred.
7
Calculating
								the CO composite emission value.
Composite emission values for CO
								shall be calculated in accordance with Equation 1 above. Unlike the NMOG+NOx
								composite emission standards, manufacturers may not comply with the CO
								composite emission standard through fleet averaging; each individual test group
								must comply with the standard. Test groups certified to 4,000-mile SFTP
								emission standards and federally-certified test groups certifying in California
								in accordance with Section H subparagraph 1.4 of "California 2015 through 2025
								Model Year Criteria Pollutant Exhaust Emission Standards and Test Procedures
								and 2017 and Subsequent Model Year Greenhouse Gas Exhaust Emission Standards
								and Test Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty
								Vehicles" are not subject to this CO emission standard.
(B)
SFTP PM Exhaust Emission
				  Standards for Passenger Cars, Light-Duty Trucks, and Medium-Duty Passenger
				  Vehicles.
The following standards are the maximum PM exhaust emissions
				  through the full useful life from 2017 through 2025 model-year LEV III LEVs,
				  ULEVs, and SULEVs in the PC, LDT, and MDPV classes when operating on the same
				  gaseous or liquid fuel they use for FTP certification. In the case of
				  fuel-flexible vehicles [LESS THAN EQUAL TO] 6,000 lbs. GVWR certified to LEV

				  vehicles > 6,000 lbs. GVWR, including vehicles certifying with carryover
				  data, shall comply with all requirements established for each consumed fuel (or
				  blend of fuels in the case of fuel-flexible vehicles). Manufacturers must
				  certify LEVs, ULEVs, and SULEVs in the PC, LDT, and MDPV classes, which are
				  certifying to LEV III FTP PM emission standards in subsection (a)(2) on a

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,
					 they may opt to run the US06 Bag 2 in lieu of the full US06 cycle. The cutoff
					 is determined by using a ratio of the engine's maximum rated horsepower, as
					 established by the engine manufacturer in the vehicle's Application for
					 Certification, to the vehicle's GVWR in pounds and does not include any
					 horsepower contributed by electric motors in the case of hybrid electric or
					 plug-in hybrid electric vehicles. Manufacturers may opt to test to the full
					 cycle regardless of the calculated ratio; in such case, manufacturers shall
					 meet the emission standards applicable to vehicles with power-to-weight ratios
					 greater than 0.024.
3
Test Weight.
Medium-duty vehicles are
					 tested at their adjusted loaded vehicle weight (average of curb weight and
					 GVWR).

Road Speed Fan.
Manufacturers have the
					 option to use a road speed modulated fan as specified in 40-CFR §
													86.107-96(d)(1)
					 or §
													1066.105, as applicable, instead
					 of a fixed speed fan for MDV SFTP testing.
5 If a manufacturer provides an engineering evaluation for
					 a test group showing that SC03 emissions are equivalent to or lower than FTP
					 emissions, the FTP emission value may be used in place of the SC03 emission
					 value when determining the composite emission value for that test group.
6
Vehicle Emission Categories.
For MDVs
					 8,501-10,000 lbs. GVWR certified prior to the 2018 model year, for each model
					 year, the percentage of MDVs certified to an SFTP emission category set forth
					 in this section
					 1961.2 shall be equal to or
					 greater than the total percentage certified to the FTP ULEV250, ULEV200,
					 SULEV170, and SULEV150 emission categories; of these vehicles, the percentage
					 of MDVs certified to an SFTP SULEV emission category shall be equal to or
					 greater than the total percentage certified to both the FTP SULEV170 and
					 SULEV150 emission categories. For MDVs 10,001-14,000 lbs. GVWR, for each model
					 year, the percentage of MDVs certified to an SFTP emission category set forth
					 in this section
					 1961.2 shall be equal to or
					 greater than the total percentage certified to the FTP ULEV400, ULEV270,
					 SULEV230, and SULEV200 emission categories; of these vehicles, the percentage
					 of MDVs certified to an SFTP SULEV emission category shall be equal to or
					 greater than the total percentage certified to both the FTP SULEV230 and
					 SULEV200 emission categories. 2018 through 2028 model year MDVs 8,501-10,000
					 lbs. GVWR certifying to the FTP ULEV250 and ULEV200 emission categories,
					 including vehicles certifying with carryover data, shall comply with the SFTP
					 ULEV standards set forth in this subsection (a)(7)(C), and those certifying to
					 FTP SULEV170 and SULEV150, including vehicles certifying with carryover data,

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,
					 they may opt to run the US06 Bag 2 in lieu of the full US06 cycle. The cutoff
					 is determined by using a ratio of the engine's horsepower to the vehicle's GVWR
					 in pounds and does not include any horsepower contributed by electric motors in
					 the case of hybrid electric or plug-in hybrid electric vehicles. Manufacturers
					 may opt to test to the full cycle regardless of the calculated ratio; in such
					 case, manufacturers shall meet the emission standards applicable to vehicles
					 with power-to-weight ratios greater than 0.024.
3
Road Speed Fan.
Manufacturers have the
					 option to use a road speed modulated fan as specified in 40-CFR §
													86.107-96(d)(1)
					 or §
													1066.105, as applicable, instead
					 of a fixed speed fan for MDV SFTP testing.
4 Manufacturers shall use Equation 1 above to calculate
					 SFTP Composite PM Emission Values for each test group subject to the emission
					 standards in this table. For MDVs 8,501-10,000 lbs. GVWR certifying to the US06
					 Bag 2 PM emission standard, the emission results from the US06 Bag 2 test shall
					 be used in place of results from the full US06 test. For MDVs 10,001-14,000
					 lbs. GVWR, the emission results from the UC test shall be used in place of
					 results from the US06 test.
5 If a manufacturer provides an engineering evaluation for
					 a test group demonstrating that SC03 PM emissions are equivalent to or lower
					 than FTP PM emissions, the FTP PM emission value may be used in lieu of the
					 SC03 PM emission value when determining the composite emission value for that
					 test group.

NMOG
				  Credit for Direct Ozone Reduction Technology.
A manufacturer that
				  certifies vehicles equipped with direct ozone reduction technologies shall be
				  eligible to receive NMOG credits that can be applied to the NMOG exhaust
				  emissions of the vehicle when determining compliance with the standard. In
				  order to receive credit, the manufacturer must submit the following information
				  for each vehicle model for which it gets credit, including, but not limited to:
(A) a demonstration of the airflow rate
				  through the direct ozone reduction device and the ozone-reducing efficiency of
				  the device over the range of speeds encountered in the Unified Cycle Driving
				  Schedule contained in Part II G. of the "California 2015 through 2025 Model
				  Year Criteria Pollutant Emission Standards and Test Procedures and 2017 and
				  Subsequent Model Year Greenhouse Gas Exhaust Emission Standards and Test
				  Procedures for Passenger Cars, Light-Duty trucks and Medium-duty
				  Vehicles";
(B) an evaluation of the
				  durability of the device for the full useful life of the vehicle; and
(C) a description of the on-board diagnostic
				  strategy for monitoring the performance of the device in-use. Using the above
				  information, the Executive Officer shall determine the value of the NMOG credit
				  based on the calculated change in the one-hour peak ozone level using an
				  approved airshed model. This credit can only be used for determining compliance
				  with the exhaust standards in subsection (a)(1) or subsection
				  1961(a)(1), as
				  applicable.
(12)
When a Federally-Certified Vehicle Model is Required in
				  California.
(A)
General
				  Requirement.
Whenever a manufacturer federally-certifies a 2015
				  through 2025 model-year passenger car, light-duty truck, or medium-duty vehicle
				  model to the standards for a particular emissions bin that are more stringent
				  than the standards for an applicable California emission category, the
				  equivalent California model may only be certified to (i) the California
				  standards for a vehicle emissions category that are at least as stringent as
				  the standards for the corresponding federal emissions bin, or (ii) the exhaust
				  emission standards to which the federal model is certified. However, where the
				  federal exhaust emission standards for the particular emissions bin and the
				  California standards for a vehicle emissions category are equally stringent,
				  the California model may only be certified to either the California standards
				  for that vehicle emissions category or more stringent California standards. The
				  federal emission bins are those contained in Tables S
				  04-1 and S
				  04-2 of
				  40 CFR section
				  86.1811-04(c), as adopted
				  February 10, 2000, and in Table 2 of
				  40 CFR section
				  86.1811.17(b), as adopted
				  April 28, 2014. The criteria for applying this requirement are set forth in
				  Part I. Section H.1 of the "California 2015 through 2025 Model Year Criteria
				  Pollutant Exhaust Emission Standards and Test Procedures and 2017 and
				  Subsequent Model Year Greenhouse Gas Exhaust Emission Standards and Test
				  Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty
				  Vehicles."
(B)
Exception
				  for clean fuel fleet vehicles.
Subsection (a)(12)(A) does not apply in
				  the case of a federally-certified vehicle model that is only 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. sec.
				  7586). In addition, the Executive Officer
				  shall exclude from the requirement a federally-certified vehicle model where
				  the manufacturer demonstrates to the Executive Officer's reasonable
				  satisfaction that the model will primarily be sold or leased to clean fuel
				  fleet operators for such applications, and that other sales or leases of the
				  model will be incidental to marketing to those clean fuel fleet
				  operators.
(13)
Emission Standard for a Fuel-Fired Heater.
Whenever a manufacturer elects to utilize an on-board
					 fuel-fired heater on any passenger car, light-duty truck or medium-duty
					 vehicle, the fuel-fired heater must meet ULEV125 standards for passenger cars
					 and light-duty trucks less than 8,500 pounds GVWR as set forth in subsection
					 (a)(1). The exhaust emissions from the fuel-fired heater shall be determined in
					 accordance with the "California Exhaust Emission Standards and Test Procedures
					 for 2009 through 2017 Model Zero-Emission Vehicles and Hybrid Electric
					 Vehicles, in the Passenger Car, Light-Duty Truck and Medium-Duty Vehicle
					 Classes" or the "California Exhaust Emission Standards and Test Procedures for
					 2018 through 2025 Model Year Zero-Emission Vehicles and Hybrid Electric
					 Vehicles, in the Passenger Car, Light-Duty Truck and Medium-Duty Vehicle
					 Classes," as applicable. If the on-board fuel-fired heater is capable of
					 operating at ambient temperatures above 40°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 86, Subpart B), as amended by the "California 2015
					 through 2025 Model Year Criteria Pollutant Exhaust Emission Standards and Test
					 Procedures and 2017 and Subsequent Model Year Greenhouse Gas Exhaust Emission
					 Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and
					 Medium-Duty Vehicles" to determine compliance with the exhaust emission
					 standards in subsection (a)(1).
