Public Hearing Date: January 26-27, 2012

Public Availability Date: February 22, 2012

Deadline for Public Comment: March 8, 2012

At its January 26-27, 2012, public hearing, the Air Resources Board (ARB or Board) 

approved amendments to the California Code of Regulations, title 13, sections 1900, 

1956.8, 1960.1, 1961, 1961.1, 1965, 1968.2, 1968.5, 1976, 1978, 2037, 2038, 2062, 

2112, 2139, 2140, 2145, 2147, 2235, and 2317; and to the following documents 

incorporated by reference therein: "California Exhaust Emission Standards and Test 

Procedures for 2001 and Subsequent Model Passenger Cars, Light-Duty Trucks, and 

Medium-Duty Vehicles," as last amended September 27, 2010; "California Evaporative 

Emission Standards and Test Procedures for 2001 and Subsequent Model Motor 

Vehicles," as last amended September 27, 2010; "California Refueling Emission 

Standards and Test Procedures for 2001 and Subsequent Model Motor Vehicles," as 

last amended September 27, 2010 ; "Specifications for Fill Pipes and Openings of Motor 

Vehicle Fuel Tanks," as last amended January 22, 1990; "California Exhaust Emission 

Standards and Test Procedures for 2004 and Subsequent Model Heavy-Duty 

Otto-Cycle Engines," as last amended September 27, 2010; "California Exhaust 

Emission Standards and Test Procedures for 2004 and Subsequent Model Heavy-Duty 

Diesel Engines and Vehicles," as last amended October 12, 2011; "California 

Environmental Performance Label Specifications for 2009 and Subsequent Model Year 

Passenger Cars, Light-Duty Trucks, and Medium-Duty Passenger Vehicles, " as 

adopted May 2, 2008; "California Test Procedure for Evaluating Substitute Fuels and 

New Clean Fuels, " as adopted November 2, 1993; and proposed new "Specifications 

for Fill Pipes and Openings of 2015 and Subsequent Motor Vehicle Fuel Tanks;" and 

proposed new "California Test Procedure for Evaluating Substitute Fuels and New 

Clean Fuels in 2015 and Subsequent Years." 

The Board also approved the adoption of new sections 1961.2 and 1961.3 in the 

California Code of Regulations, title 13, and new "California 2015 and Subsequent 

Model Criteria Pollutant Exhaust Emission Standards and Test Procedures and 2017 

and Subsequent Model Greenhouse Gas Exhaust Emission Standards and Test 
2

Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles" 

incorporated by reference therein, and amendment of the following document 

incorporated by reference therein: "California Non-Methane Organic Gas Test 

Procedures," as last amended July 30, 2002. 

Together, these amendments reduce emissions of criteria pollutants from new light- and 

medium-duty vehicles by: reducing fleet average emissions from new passenger cars, 

light-duty trucks, and medium-duty passenger vehicles to super ultra-low-emission 

vehicle levels by 2025; replacing separate non-methane organic gas (NMOG) and 

oxides of nitrogen standards (NOx) with combined NMOG plus NOx standards; 

increasing full useful life durability requirements from 120,000 miles to 150,000 miles, 

which guarantees vehicles operate longer at these proposed extremely low emission 

particulate levels; creating a backstop to assure continued production of super-ultra-lowemission vehicles after partial zero-emission vehicles as a category are moved from the 

Zero-Emission Vehicle program to the LEV III program in 2018; establishing more 

stringent particulate matter standards for light- and medium-duty vehicles; establishing 

zero fuel evaporative emission standards for passenger cars and light-duty trucks, and 

more stringent evaporative standards for medium-duty vehicles; establishing more 

stringent supplemental federal test procedure (SFTP) standards for passenger cars and 

light-duty trucks; and, for the first time, requiring medium-duty vehicles to meet SFTP 

standards. Other minor amendments (e.g., in-use verification testing requirements, 

reporting requirements, etc.) are proposed to align existing related procedures with the 

principal amendments. 

The amendments also establish more stringent greenhouse gas regulations that: are 

comprised of three emission standards; a carbon dioxide (CO2) standard, a methane 

standard and a nitrous oxide standard; use a footprint-based approach to reduce 

emissions from new light-duty vehicles and medium-duty passenger vehicles; provide 

credits for improvements to the vehicle air conditioning system (either from the use of a 

refrigerant with a low Global Warming Potential or by incorporating improvements to the 

efficiency of the system); provide credits for technologies that reduce CO2 emissions but 

are not measured on the applicable test cycles; and provide credits for technology 

innovations on the largest of pickup trucks.

At the hearing, the staff presented, and the Board approved modifications to the 

regulations originally proposed in the Staff Report released on December 7, 2011, in

response to comments received after the Staff Report was published. These 

modifications include: allowing 2015-2019 MY LEV II vehicles to certify to combined 

NMOG+NOx standards instead of separate NMOG and NOx standards; allowing

manufacturers to meet the phase-in requirements for the LEV III medium-duty vehicle 

particulate standards based on a percentage of the combined sales of medium-duty 

vehicles weighing 8,501 to 10,000 pounds gross vehicle weight rating (GVWR) and 

medium-duty vehicles weighing 10,001 to 14,000 pounds GVWR, rather than separate 

percentages for the 2 weight classes; allowing early compliance with 150,000-mile 

SFTP standards for model year 2014 vehicles; requiring LEV III flex-fueled vehicles to 
3

test only on LEV III certification gasoline; allowing interim in-use SFTP emission 

standards for new certifications through the 2020 model year; adding NMOG+NOx fleet 

average standards for the 2014 model year; allowing manufacturers to use projected 

sales data rather than actual sales data to determine the minimum number of LEV III 

super-ultra-low-emission vehicles they must produce in the 2018 and subsequent model 

years; allowing vehicles certified to federal standards to be included in the fleet average 

NMOG+NOx calculation based on the actual standards to which they certify; eliminating

the requirement that a manufacturer that elects to pool its emissions -- from vehicles 

sold in California, with those of other states adopting California’s standards under 

section 177 of the federal Clean Air Act (42 U.S.C. § 7507) -- report that selection to 

ARB prior to the start of each model year to which that selection applies; revising the 

provisions for trading evaporative emission fleet-average credits among certain vehicle 

categories; allowing manufacturers to use projected sales data rather than actual sales 

data to determine the minimum number of vehicles they must produce in the 2015-2017 

model years that meet the proposed evaporative emission standards and base 

compliance for this requirement upon the average number of vehicles produced over 

the 2015-2017 time period in lieu of a year-by-year requirement; modifying the section 

177 state pooling compliance option to specifically set forth required submittal 

information and to reduce the Executive Officer notification requirement; allowing

optional early compliance in the 2014 model year with the proposed evaporative 

emission standards; and revising the refueling exemption for incomplete medium-duty 

vehicles.

Board Resolution 12-11 approved with modifications to sections 1900, 1956.8, 1960.1, 

1961, 1961.1, 1961.2, 1961.3, 1965, 1968.2, 1968.5, 1976, 1978, 2037, 2038, 2062,

Date of Hearing: January 26-27, 2012

1. Amend title 13, CCR, section 1900 to read as follows:

§ 1900. Definitions.

* * * *

(b) In addition to the definitions incorporated under subdivision (a), the 

following definitions shall govern the provisions of this chapter. 

* * * *

(22) “Small volume manufacturer” means, with respect to the 2001 and 

subsequent model-years, a manufacturer with California sales less than 4,500 new 

passenger cars, light-duty trucks, medium-duty vehicles, heavy-duty vehicles and 

heavy-duty engines based on the average number of vehicles sold for the three 

previous consecutive model years for which a manufacturer seeks certification as a 

small volume manufacturer; however, for manufacturers certifying for the first time in 

California model-year sales shall be based on projected California sales. A 

manufacturer’s California sales shall consist of all vehicles or engines produced by the 

manufacturer and delivered for sale in California, except that vehicles or engines 

produced by the manufacturer and marketed in California by another manufacturer 

under the other manufacturer’s nameplate shall be treated as California sales of the 

marketing manufacturer. Except as provided in the next paragraph, beginning with for

the 2009 through 2017 model years, the annual sales from different firms shall be 

aggregated in the following situations: (1) vehicles produced by two or more firms, one 

of which is 10% or greater part owned by another; or (2) vehicles produced by any two 

or more firms if a third party has equity ownership of 10% or more in each of the firms; 

or (3) vehicles produced by two or more firms having a common corporate officer(s) 

who is (are) responsible for the overall direction of the companies; or (4) vehicles 

imported or distributed by all any firms where the vehicles are manufactured by the 

same entity and the importer or distributor is an authorized agent of the entity. 

Notwithstanding the provisions of this paragraph, upon application to the Executive 

Officer, a manufacturer may be classified as a “small volume manufacturer” for the 2015 

through 2017 model years if the Executive Officer determines that it is operationally 

independent of the firm that owns 10% or more of the applicant or has a greater than 

10% equity ownership in the applicant based on the criteria provided in the last 

paragraph of this subsection (b)(22).

 

For purposes of compliance with the zero-emission vehicle requirements, heavy-duty 

vehicles and engines shall not be counted as part of a manufacturer’s sales. For 

purposes of applying the 2005 and subsequent through 2017 model year zero-emission 

vehicle requirements for small-volume manufacturers under sections 1962(b) and 

1962.1(b), the annual sales from different firms shall be aggregated in the case of (1) 
A-3

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

vehicles produced by two or more firms, each one of which either has a greater than 

50% equity ownership in another or is more than 50% owned by another; or (2) vehicles 

produced by any two or more firms if a third party has equity ownership of greater than 

50% in each firm. Notwithstanding the provisions of this paragraph, upon application to 

the Executive Officer, a manufacturer may be classified as a “small volume 

manufacturer” for the 2015 through 2017 model years if the Executive Officer 

determines that it is operationally independent of the firm that owns 50% or more of the 

applicant or has a greater than 50% equity ownership in the applicant based on the 

criteria provided in the last paragraph of this subsection (b)(22). 

Except as provided in the next paragraph, fFor the 2018 and subsequent model years, 

the annual sales from different firms shall be aggregated in the following situations: (1) 

vehicles produced by two or more firms, one of which is 33.4% or greater part owned by 

another; or (2) vehicles produced by any two or more firms if a third party has equity 

ownership of 33.4% or more in each of the firms; or (3) vehicles produced by two or 

more firms having a common corporate officer(s) who is (are) responsible for the overall 

direction of the companies; or (4) vehicles imported or distributed by any firms where 

the vehicles are manufactured by the same entity and the importer or distributor is an 

authorized agent of the entity. Notwithstanding the provisions of this paragraph, upon 

application to the Executive Officer, a manufacturer may be classified as a “small 

volume manufacturer” for the 2018 and subsequent model years if the Executive Officer 

determines that it is operationally independent of the firm that owns 33.4% or more of 

the applicant or has a greater than 33.4% equity ownership in the applicant based on 

the criteria provided in the last paragraph of this subsection (b)(22).

For the purposes of this paragraph, all manufacturers whose annual sales are 

aggregated together under the provisions of this subsection (b)(22) shall be defined as 

“related manufacturers.” Notwithstanding such aggregation, the Executive Officer may 

make a determination of operational independence if all of the following criteria are met 

for at least 24 months preceding the application submittal: (1) for the three years 

preceding the year in which the initial application is submitted, the average California 

sales for the applicant does not exceed 4,500 vehicles per year; (2) no financial or other 

support of economic value is provided by related manufacturers for purposes of design, 

parts procurement, R&D and production facilities and operation, and any other 

transactions between related manufacturers are conducted under normal commercial 

arrangements like those conducted with other parties, at competitive pricing rates to the 

manufacturer; (3) related manufacturers maintain separate and independent research 

and development, testing, and production facilities; (4) related manufacturers do not use 

any vehicle powertrains or platforms developed or produced by related manufacturers; 

(5) patents are not held jointly with related manufacturers; (6) related manufacturers 

maintain separate business administration, legal, purchasing, sales, and marketing 

departments, as well as autonomous decision-making on commercial matters; (7) the 

overlap of the Board of Directors between related manufacturers is limited to 25% with 

no sharing of top operational management, including president, chief executive officer, 
A-4

Date of Hearing: January 26-27, 2012

chief financial officer, and chief operating officer, and provided that no individual 

overlapping director or combination of overlapping directors exercises exclusive 

management control over either or both companies; and (8) parts or components supply 

between related companies must be established through open market process, and to 

the extent that the manufacturer sells parts/components to non-related manufacturers, it 

does so through the open market a competitive pricing. Any manufacturer applying for 

operational independence must submit to ARB an Attestation Engagement from an 

independent certified public accountant or firm of such accountants verifying the 

accuracy of the information contained in the application, as defined by and in

accordance with the procedures established in 40 C.F.R. §80.125, as last amended 

January 19, 2007, which is incorporated herein by reference. The applicant must 

submit information to update any of the above eight criteria as material changes to any 

of the criteria occur. If there are no material changes to any of the criteria, the applicant 

must certify that to the Executive Officer annually. With respect to any such changes, 

the Executive Officer may consider extraordinary conditions (e.g., changes to economic 

conditions, unanticipated market changes, etc.) and may continue to find the applicant 

to be operationally independent. In the event that a manufacturer loses eligibility as a 

“small volume manufacturer” after a material change occurs, the manufacturer must 

begin compliance with the primary emissions program in the third model year after the 

model year in which the manufacturer loses its eligibility. The Executive Officer may, in 

his or her discretion, re-establish lost “small volume manufacturer” status if the 

manufacturer shows that it has met the operational independence criteria for three 

consecutive years.

3. Adopt new title 13, CCR, section 1961.2 to read as follows: (Note: the entire text of 

section 1961.2 set forth below is new language proposed to be added to the California 

Code of Regulations.)

§ 1961.2. Exhaust Emission Standards and Test Procedures - 2015 and 

Subsequent Model Passenger Cars, Light-Duty Trucks, and Medium-Duty 

Vehicles.

Introduction. This section 1961.2 contains the California “LEV III” exhaust emission 

standards for 2015 and subsequent model year passenger cars, light-duty trucks, and 

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.

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 fleetwide 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 phasein 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(c) and (h). 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.

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 mediumduty 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 mediumduty 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, the District of Columbia, and all states that have adopted California's criteria 
A-9

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

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, the District of 

Columbia, and all states 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) Exhaust Emission Standards.

(1) “LEV III” Exhaust Standards. The following standards are the maximum 

exhaust emissions for the full useful life from new 2015 and subsequent model year 

“LEV III” passenger cars, light-duty trucks, and medium-duty vehicles, including fuelflexible, bi-fuel and dual fuel vehicles when operating on the gaseous or alcohol fuel 

they are designed to use.: 2015 – 2019 model-year LEV II LEV vehicles may be 

certified to the NMOG+NOx numerical values for LEV160, LEV395, or LEV630, 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 subsections 1961(a)(1) and 1961(a)(4); LEV II ULEV vehicles may be 

certified to the NMOG+NOx numerical values for ULEV125, ULEV340, or ULEV570, 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 subsections 1961(a)(1) and 1961(a)(4); and LEV II SULEV vehicles may 

be certified to the NMOG+NOx numerical values for SULEV30, SULEV170, or 

SULEV230, as applicable, in 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 subsections 1961(a)(1) and 1961(a)(4). Such vehicles will be 

treated as LEV II vehicles for purposes of the fleet-wide phase-in requirements.

(D) 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 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. The cumulative total must be equal to or 

greater than 490 in the 2021 model year 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 equivalent PM

emission reductions are achieved 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
A-12

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. The cumulative total must be equal to or greater than 500 in the 2028 

model year to be considered equivalent. A manufacturer may add vehicles 

introduced before the 2025 model year (e.g., the percent of vehicles introduced 

in 2024 would be multiplied by 4) to the cumulative total.

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. The cumulative total must be equal to or greater than 490 in the 

2021 model year 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.

(6) Highway NMOG + NOx Standard. The maximum emissions of nonmethane organic gas plus oxides of nitrogen measured on the federal Highway Fuel 

Economy Test (HWFET; 40 CFR 600 Subpart B, as modified by the “California 2015 

and Subsequent Model Criteria Pollutant Exhaust Emission Standards and Test 

Procedures and 2017 and Subsequent Model Greenhouse Gas Exhaust Emission 

Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and MediumDuty Vehicles,” must not be greater than the applicable LEV III NMOG+NOx standard 

set forth in subsection (a)(1). Both the sum of the NMOG+NOx emissions and the 

HWFET standard must be rounded in accordance with ASTM E29-67 to the nearest 

0.001 g/mi before being compared.

(7) 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 and subsequent model year LEVs, ULEVs, and SULEVs in the PC, LDT, 
A-13

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 and subsequent model-year 

LEV III LEVs, ULEVs, and SULEVs when operating on the same any gaseous or 

liquid fuel they use for FTP certification. In the case of fuel-flexible vehicles, SFTP 

compliance shall be demonstrated using the LEV III certification gasoline specified in 

Part II, Section A.100.3.1.2 of the “California 2015 and Subsequent Model Criteria 

Pollutant Exhaust Emission Standards and Test Procedures and 2017 and 

Subsequent Model Greenhouse Gas Exhaust Emission Standards and Test 

Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles.”

1 Vehicle Emission Category. 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 and subsequent 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. In the case of fuel-flexible vehicles,

SFTP compliance shall be demonstrated using the LEV III certification gasoline 

specified in Part II, Section A.100.3.1.2 of the “California 2015 and Subsequent 

Model Criteria Pollutant Exhaust Emission Standards and Test Procedures and 2017 

and Subsequent Model Greenhouse Gas Exhaust Emission Standards and Test 

Procedures for Passenger Cars, Light-Duty Trucks, and Medium-Duty 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]
A-15

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

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:

with the “California 2015 and Subsequent Model Criteria Pollutant Exhaust Emission Standards and Test 

Procedures and 2017 and Subsequent Model 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. For carry-over test groups 

certified to LEV II FTP emission standards, SFTP emission values shall be converted to NMOG+NOx and 

projected out to 120,000 miles or 150,000 miles (depending on LEV II FTP certification) using 

deterioration factors or aged components., 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. In lieu of deriving a 

deterioration factor specific to SFTP test cycles, carry-over 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 SFTP 4k standards, that value may be used in the sales-weighted 

fleet-average without applying an additional deterioration factor. 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 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 its sales-weighted fleet-average NMOG+NOx composite emission value as follows.

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 7 of this table, for carry-over LEV II test groups. 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 manufacturer 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 would not be able to meet the proposed CO composite emission standard through fleet 

averaging: each individual test group must comply with the standard. Test groups certified to 4,000-mile

1 Manufacturers shall use Equation 1 in subsection (a)(7)(A)2 to calculate SFTP Composite Emission Values for 

each test group subject to the emission standards in this table. 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. 2 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). 4 Road Speed Fan. Manufacturers have the option to use a road speed modulated fan as specified in § 86.107–

96(d)(1) 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. 56 Vehicle Emission Categories. For MDVs 8,501-10,000 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 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. 

(D) SFTP PM Exhaust Emission Standards for Medium-Duty Vehicles. The 

following standards are the maximum PM composite emission values for the full useful 

life of 2017 and subsequent model-year LEV III LEVs, ULEVs, and SULEVs when 

operating on any the same gaseous or liquid fuel they use for FTP certification. In the 

case of fuel-flexible vehicles, SFTP compliance shall be demonstrated using the LEV III 

certification gasoline specified in Part II, Section A.100.3.1.2 of the “California 2015 and

1. Pooling Provision.

a. For each model year, a manufacturer must demonstrate 

compliance with the fleet average requirements in this subsection (b)(1)(A) 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 passenger 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 passenger 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, the District of Columbia, and 

all states 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).

b. 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.

c. 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, the District of Columbia, and all states 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).

d. A manufacturer that selects compliance Option 2 must provide to the 

Executive Officer separate values for the number of vehicles in each test group

produced and delivered for sale in the District of Columbia and for each individual 

state within the average.

2. PZEV Anti-Backsliding Requirement. In the 2018 and subsequent 

model years, a manufacturer must produce and deliver for sale in California a 

minimum percentage of its passenger car and light-duty truck fleet that certifies to

4. Adopt new title 13, CCR, section 1961.3 to read as follows: (Note: the entire text of 

section 1961.3 set forth below is new language proposed to be added to the California 

Code of Regulations.)

§ 1961.3. Greenhouse Gas Exhaust Emission Standards and Test Procedures -

2017 and Subsequent Model Passenger Cars, Light-Duty Trucks, and MediumDuty Vehicles.

* * * *

(a) Greenhouse Gas Emission Requirements. 

* * * *

(5) Calculation of Fleet Average Carbon Dioxide Value. 

* * * *

(D) For each model year, a manufacturer must demonstrate 

compliance with the fleet average requirements in section (a)(1) 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 passenger vehicles that are certified to the California 

exhaust emission standards in section 1961.3, and are produced and 

delivered for sale in California; or

Option 2: the total number of passenger cars, light-duty trucks, 

and medium-duty passenger vehicles that are certified to the California 

exhaust emission standards in this section 1961.3, and are produced and 

delivered for sale in California, the District of Columbia, and all states that 

have adopted California's greenhouse gas emission standards for that 

model year pursuant to Section 177 of the federal Clean Air Act (42 U.S.C. 

§ 7507).

1. 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. 

2. When a manufacturer is demonstrating compliance using Option 

2 for a given model year, the term "in California" as used in section 1961.3 

means California, the District of Columbia, and all states that have adopted 
A-34

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

California's greenhouse gas emission standards for that model year pursuant 

to Section 177 of the federal Clean Air Act (42 U.S.C. § 7507).

3. A manufacturer that selects compliance Option 2 must provide 

to the Executive Officer separate values for the number of vehicles in each 

model type and footprint value produced and delivered for sale in the District 

of Columbia and for each individual state within the average and the City CO2

Value and Highway CO2 exhaust emission values that apply to each model 

type and footprint value.

(6) Credits for Reduction of Air Conditioning Direct Emissions. 

Manufacturers may generate A/C Direct Emissions Credits by implementing specific air 

conditioning system technologies designed to reduce air conditioning direct emissions

over the useful life of their vehicles. A manufacturer may only use an A/C Direct 

Emissions Credit for vehicles within a model type upon approval of the A/C Direct 

Emissions Credit for that model type by the Executive Officer. The conditions and 

requirements for obtaining approval of an A/C Direct Emissions Credit are described in 

(A) through (F), below. 

* * * *

(B) To obtain approval of the A/C Direct Emissions Credit, the 

manufacturer must demonstrate through an engineering evaluation that the A/C 

system under consideration reduces A/C direct emissions. The demonstration must 

include all of the following elements:

• the amount of A/C Direct Emissions Credit requested, in grams of CO2-

equivalent per mile (gCO2e/mi); 

• the calculations identified in section (a)(6)(C) justifying that credit amount;

• schematic of the A/C system; 

• specifications of the system components with sufficient detail to allow 

reproduction of the calculation; and

• a justification that the number of fittings and joints has been minimized and 

components have been optimized to minimize leakage an explanation 

describing what efforts have been made to minimize the number of fittings 

and joints and to optimize the components in order to minimize leakage. 

Calculated values must be carried to at least three significant figures throughout the 

calculations, and the final credit value must be rounded to one tenth of a gram of 

CO2-equivalent per mile (gCO2e/mi).

(10) Greenhouse Gas In-Use Compliance Standards. The in-use exhaust 

CO2 emission standard shall be the combined city/highway exhaust emission value 

calculated according to the provisions of subsection (a)(5)(A) for the vehicle model type 

and footprint value multiplied by 1.1 and rounded to the nearest whole gram per mile. 

For vehicles that are capable of operating on multiple fuels, a separate value shall be 

determined for each fuel that the vehicle is capable of operating on. These standards 

apply to in-use testing performed by the manufacturer pursuant to the “California 2015 

and Subsequent Model Criteria Pollutant Exhaust Emission Standards and Test

Procedures and 2017 and Subsequent Model Greenhouse Gas Exhaust Emission

Standards and Test Procedures for Passenger Cars, Light-Duty Trucks, and MediumDuty Vehicles.”

(b)(1) Evaporative emissions for 1978 and subsequent model gasoline-fueled, 1983 

and subsequent model liquefied petroleum gas-fueled, and 1993 and subsequent model 

alcohol-fueled motor vehicles and hybrid electric vehicles subject to exhaust emission 

standards under this article, except petroleum-fueled diesel vehicles, compressed 

natural gas-fueled vehicles, hybrid electric vehicles that have sealed fuel systems which 

can be demonstrated to have no evaporative emissions, and motorcycles, shall not 

exceed the following standards:

Procedures for 2001 and Subsequent Model Motor Vehicles,” incorporated by 

reference in section 1976(c), shall not exceed:

* * * *

5 Calculation of Hydrocarbon Credits or Debits for the Fleet-Average Option. 

(1) Calculation of Hydrocarbon Credits or Debits. For each emission standard category in the model 

year, a manufacturer shall calculate the hydrocarbon credits or debits, as follows:

[(Applicable Hydrocarbon Emission Standard for the Emission Standard Category) – (Manufacturer’s 

Fleet-Average Hydrocarbon Emission Value for the Emission Standard Category)] X (Total Number of 

Affected Vehicles)

where “Total Number of Affected Vehicles” = the total number of vehicles in the evaporative 

families participating in the fleet-average option, which are produced and delivered for 

sale in California, for the emission standard category of the given model year.
A-37

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

A negative number constitutes hydrocarbon debits, and a positive number constitutes hydrocarbon 

credits accrued by the manufacturer for the given model year. Hydrocarbon credits earned in a given 

model year shall retain full value through the fifth model year after they are earned. At the beginning 

of the sixth model year, the hydrocarbon credits will have no value.

(2) Procedure for Offsetting Hydrocarbon Debits. A manufacturer shall offset hydrocarbon debits with 

hydrocarbon credits for each emission standard category within three model years after the debits 

have been incurred. If total hydrocarbon debits are not equalized within three model years after they 

have been incurred, the manufacturer shall be subject to the Health and Safety Code section 43211 

civil penalties 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 hydrocarbon 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 shall be determined by dividing the total amount of hydrocarbon debits for 

the model year in the emission standard category by the applicable hydrocarbon emission standard 

for the model year in which the debits were first incurred.

Additionally, a manufacturer may use the excess hydrocarbon credits from the emission standard 

categories of (1) passenger cars and light-duty trucks 6,000 pounds GVWR and under, and 0 - 3,750 

pounds LVW and (2) light-duty trucks 6,000 pounds GVWR and under, and 3,751 – 5,750 pounds 

LVW to equalize the hydrocarbon debits that remain at the end of the three model year offset period 

of any emission standard category. to equalize the hydrocarbon debits that remain at the end of the 

three model year offset period: (1) hydrocarbon credits may be exchanged between passenger cars 

and light-duty trucks 6,000 pounds GVWR and under and 0-3,750 pounds LVW, and light-duty trucks 

6,000 pounds GVWR and under and 3,751-5,750 pounds LVW and (2) hydrocarbon credits may be 

exchanged between light-duty trucks 6,001-8,500 pounds GVWR and medium-duty passenger 

vehicles, and medium-duty vehicles and heavy-duty vehicles.

6 Vehicle Canister Bleed Emission. Compliance with the canister bleed emission standard shall be 

determined based on the Bleed Emission Test Procedure described in the “California Evaporative 

Emission Standards and Test Procedures for 2001 and Subsequent Model Motor Vehicles,” 

incorporated by reference in section 1976(c), and demonstrated on a stabilized canister system. 

Vehicles with a non-integrated refueling canister-only system are exempt from the canister bleed 

emission standard.

2. Phase-In Schedule. For each model year, a manufacturer shall 

certify, at a minimum, the specified percentage of its vehicle fleet to the evaporative 

emission standards set forth in section 1976(b)(1)(G)1.a. or section 

1976(b)(1)(G)1.b., according to the schedule set forth below. For the purpose of this 

section 1976(b)(1)(G)2., the manufacturer's vehicle fleet consists of the vehicles 

produced and delivered for sale by the manufacturer in California that are subject to 

the emission standards in section 1976(b)(1)(G)1. All 2015 through 2022 model 

motor vehicles that are not subject to these standards pursuant to the phase-in 

schedule shall comply with the requirements for 2004 through 2014 model motor 

vehicles, as described in section 1976(b)(1)(F).

1 For the 2018 through 2022 model years only, a manufacturer may use an alternate phase-in schedule 

to comply with the phase-in requirements. An alternate phase-in schedule must achieve equivalent 

compliance volume by the end of the last model year of the scheduled phase-in (2022). The 

compliance volume is the number calculated by multiplying the percent of vehicles (based on the 

manufacturer’s projected sales volume of all vehicles) meeting the new requirements in each model 

year by the number of years implemented prior to and including the last model year of the scheduled 

phase-in, then summing these yearly results to determine a cumulative total. The cumulative total of 

the five year (60/60/80/80/100) scheduled phase-in set forth above is calculated as follows: (60*5 

years) + (60*4 years) + (80*3 years) + (80*2 years) + (100*1 year) = 1040. Accordingly, the required 

cumulative total for any alternate phase-in schedule of these emission standards is 1040. The 

Executive Officer shall consider acceptable any alternate phase-in schedule that results in an equal 

or larger cumulative total by the end of the last model year of the scheduled phase-in (2022).

2 Small volume manufacturers are not required to comply with the phase-in schedule set forth in this 

table. Instead, they shall certify 100 percent of their 2022 and subsequent model year vehicle fleet to 

the evaporative emission standards set forth in section 1976(b)(1)(G)1.a. or section 1976(b)(1)(G)1.b. 

3 The percentage of vehicle fleet averaged across the 2015, 2016, and 2017 model years shall be used 

to determine compliance with this requirement.

34 The minimum percentage required in the 2015, 2016, and 2017 model years is determined by 

averaging the percentage of vehicles certified to the emission standards in section 1976(b)(1)(E) in 

each of the manufacturer’s 2012, 2013, and 2014 model year vehicle fleets. For the purpose of 

calculating this average, a manufacturer shall use the percentage of vehicles produced and delivered 

for sale in California for the 2012, and 2013, and 2014 model years, and the percentage of projected 

sales in California for the 2014 model year.. A manufacturer may calculate this average percentage 

using the projected sales for these model years in lieu of actual sales.

3. Carry-Over of 2014 Model-Year Evaporative Families Certified to 

the Zero-Fuel Evaporative Emission Standards. A manufacturer may carry over 

2014 model motor vehicles certified to the zero-fuel (0.0 grams per test) evaporative 

emission standards set forth in section 1976(b)(1)(E) through the 2018 model year

4. Pooling Provision. The following pooling provision applies to the 

fleet-average option for the Highest Whole Vehicle Diurnal Plus Hot Soak Emission 

Standard in section 1976(b)(1)(G)1.b. and to the phase-in requirements in section 

1976(b)(1)(G)2. 

a. For the fleet-average option set forth in section 1976(b)(1)(G)1.b., a 

manufacturer must demonstrate compliance, for each model year, based on one 

of two options applicable throughout the model year, either:

Pooling Option 1: the total number of passenger cars, light-duty 

trucks, medium-duty passenger vehicles, medium-duty vehicles, and 

heavy-duty vehicles that are certified to the California evaporative 

emission standards in section 1976(b)(1)(G)1.b., and are produced 

and delivered for sale in California; or

Pooling Option 2: the total number of passenger cars, light-duty 

trucks, medium-duty passenger vehicles, medium-duty vehicles, and 

heavy-duty vehicles that are certified to the California evaporative 

emission standards in section 1976(b)(1)(G)1.b., and are produced 

and delivered for sale in California, the District of Columbia, and all 

states that have adopted California's evaporative emission standards 

set forth in section 1976(b)(1)(G)1. for that model year pursuant to 

section 177 of the federal Clean Air Act (42 U.S.C. § 7507).

b. For the phase-in requirements in section 1976(b)(1)(G)2., a 

manufacturer must demonstrate compliance, for each model year, based on one 

of two options applicable throughout the model year, either:

Pooling Option 1: the total number of passenger cars, light-duty 

trucks, medium-duty passenger vehicles, medium-duty vehicles, and

heavy-duty vehicles that are certified to the California evaporative 

emission standards in section 1976(b)(1)(G)1., and are produced and 

delivered for sale in California; or

Pooling Option 2: the total number of passenger cars, light-duty 

trucks, medium-duty passenger vehicles, medium-duty vehicles, and 

heavy-duty vehicles that are certified to the California evaporative 

emission standards in section 1976(b)(1)(G)1., and are produced and 

delivered for sale in California, the District of Columbia, and all states 

that have adopted California's evaporative emission standards set forth 

in section 1976(b)(1)(G)1. for that model year pursuant to section 177 

of the federal Clean Air Act (42 U.S.C. § 7507).

c. A manufacturer that selects Pooling Option 2 must notify the 

Executive Officer of that selection in writing before the start of the applicable 

model year or must comply with Pooling 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.

d. When a manufacturer is demonstrating compliance using Pooling 

Option 2 for a given model year, the term "in California" as used in section 

1976(b)(1)(G) means California, the District of Columbia, and all states that have 

adopted California's evaporative emission standards for that model year pursuant 

to Section 177 of the federal Clean Air Act (42 U.S.C. § 7507).

e. A manufacturer that selects Pooling Option 2 must provide to the 

Executive Officer separate values for the number of vehicles in each evaporative 

family produced and delivered for sale in the District of Columbia and for each 

individual state within the average.

5. Optional Certification for 2014 Model Motor Vehicles. A 

manufacturer may optionally certify its 2014 model motor vehicles to the evaporative 

emission standards set forth in section 1976(b)(1)(G)1.

and heavy-duty engines in its product line are fewer than 4,500 units based on the average 

number of vehicles sold for the three previous consecutive model years for which a manufacturer 

seeks certification. A manufacturer's California sales shall consist of all vehicles or engines 

produced by the manufacturer and delivered for sale in California, except that vehicles or 

engines produced by the manufacturer and marketed in California by another manufacturer under 

the other manufacturer's nameplate shall be treated as California sales of the marketing 

manufacturer. 

Except as provided in the last paragraph of this definition, Ffor the 2015 through 2017 

model years, the annual sales from different firms shall be aggregated in the following situations: 

(1) vehicles produced by two or more firms, one of which is 10% or greater part owned by 

another; or (2) vehicles produced by any two or more firms if a third party has equity ownership 

of 10% or more in each of the firms; or (3) vehicles produced by two or more firms having a 

common corporate officer(s) who is (are) responsible for the overall direction of the companies;

same entity and the importer or distributor is an authorized agent of the entity.

Except as provided in the last paragraph of this definition, Ffor the 2018 and subsequent 

model years, the annual sales from different firms shall be aggregated in the following situations: 

(1) vehicles produced by two or more firms, one of which is 33.4% or greater part owned by 

another; or (2) vehicles produced by any two or more firms if a third party has equity ownership 

of 33.4% or more in each of the firms; or (3) vehicles produced by two or more firms having a 

common corporate officer(s) who is (are) responsible for the overall direction of the companies;

same entity and the importer or distributor is an authorized agent of the entity.

For the purposes of this paragraph, all manufacturers whose annual sales are aggregated together 

under the provisions of this definition shall be defined as “related manufacturers.” 

Notwithstanding such aggregation, the Executive Officer may make a determination of 

operational independence if all of the following criteria are met for at least 24 months preceding 

the application submittal: (1) for the three years preceding the year in which the initial 

application is submitted, the average California sales for the applicant does not exceed 4,500 

vehicles per year; (2) no financial or other support of economic value is provided by related 

manufacturers for purposes of design, parts procurement, R&D and production facilities and 

operation, and any other transactions between related manufacturers are conducted under normal 

commercial arrangements like those conducted with other parties, at competitive pricing rates to 

the manufacturer; (3) related manufacturers maintain separate and independent research and 

development, testing, and production facilities; (4) related manufacturers do not use any vehicle 

powertrains or platforms developed or produced by related manufacturers; (5) patents are not 

held jointly with related manufacturers; (6) related manufacturers maintain separate business 

administration, legal, purchasing, sales, and marketing departments, as well as autonomous 

decision-making on commercial matters; (7) the overlap of the Board of Directors between 

related manufacturers is limited to 25% with no sharing of top operational management, 

including president, chief executive officer, chief financial officer, and chief operating officer, 

and provided that no individual overlapping director or combination of overlapping directors 

exercises exclusive management control over either or both companies; and (8) parts or 

components supply between related companies must be established through open market process, 

and to the extent that the manufacturer sells parts/components to non-related manufacturers, it 

does so through the open market a competitive pricing. Any manufacturer applying for 

operational independence must submit to ARB an Attestation Engagement from an independent

2.1 Amend 40 CFR §86.1810-09(i) as follows:

* * * *

2.1.4 Delete subparagraph (6); replace with: Air to Fuel Ratio Requirement. 

With the exception of cold-start conditions, warm-up conditions and rapid-throttle motion 

conditions (“tip-in” or “tip-out” conditions), the air to fuel ratio shall not be richer at any 

time than, for a given engine operating condition (e.g., engine speed, manifold pressure, 

coolant temperature, air charge temperature, and any other parameters), the leanest air to fuel 

mixture required to obtain maximum torque (lean best torque), with a tolerance of three six

percent of the fuel consumption. The emission control system shall remain in the operating 

mode producing the best balance of HC, CO, and NOx catalyst efficiency (e.g. closed 

loop/stoichiometric operation on 3-way catalyst systems) under all conditions, except when 

required for engine component temperature protection, driver power request, start enrichment 

requirements, fuel shut-off situations (decelerations, rev limiter, torque management, etc.), or 

certain component malfunctions preventing safe closed-loop operation. The Executive 

Officer may approve a manufacturer's request for approval to use additional enrichment in 

subsequent testing if the manufacturer demonstrates that additional enrichment is needed to 

protect the vehicle, occupants, engine, or emission control hardware.

* * * *

2.1.6 Delete subparagraph (8); replace with: Small Volume Provisions. Small 

volume manufacturers of PCs, LDTs, and MDVs shall certify 100% of their PC, LDT, and 

MDV fleet in 2022 and subsequent model years under the 150,000-mile SFTP requirements 

in section E.1.2.2.

* * * *

2.2 For gasoline and diesel-fueled LEV II and LEV III vehicles, manufacturers may 

measure non-methane hydrocarbons (NMHC) in lieu of NMOG. Manufacturers shall multiply 

NMHC measurements by an adjustment factor of 1.03 before adding it to the measured NOx 

emissions and comparing with the NMOG+NOx standard to determine compliance with that 

standard.

1.2.2.1.2 SFTP NMOG+NOx and CO Composite Exhaust 

Emission Standards. For the 2015 and subsequent model years, a manufacturer 

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. In the case of fuel-flexible

vehicles, SFTP compliance shall be demonstrated using the LEV III certification 

gasoline specified in Part II, Section A.100.3.1.2. 

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 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:

procedures. 2 Determining NMOG+NOx Composite Emission Values of LEV II Test Groups. For carry-over test groups certified 

to LEV II FTP emission standards, SFTP emission values shall be converted to NMOG+NOx and projected out to 

120,000 miles or 150,000 miles (depending on LEV II FTP certification) using deterioration factors or aged 

components., 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. In lieu of deriving a deterioration factor specific to SFTP test cycles, 

carry-over test groups may use the applicable deterioration factor from the FTP cycle in order to determine the carryover 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 SFTP 4k standards, that value may be used in the salesweighted fleet-average without applying an additional deterioration factor. 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 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 its 

sales-weighted fleet-average NMOG+NOx composite emission value as follows.

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 manufacturer 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 would not be able to 

meet the proposed 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 are not subject to this CO emission 

standard.

1.2.2.2 SFTP PM Exhaust Emission Standards for Passenger Cars, LightDuty Trucks, and Medium-Duty Passenger Vehicles. The following standards are the 

maximum PM exhaust emissions through the full useful life from 2017 and subsequent 

model-year LEV III LEVs, ULEVs, and SULEVs in the PC, LDT, and MDPV classes 

when operating on any the same gaseous or liquid fuel they use for FTP certification. In 

the case of flex-fueled vehicles, SFTP compliance shall be demonstrated using the LEV 

III certification gasoline specified in Part II, Section A.100.3.1.2.

1 Manufacturers shall use Equation 1 in subsection E.1.2.2.1.2 to calculate SFTP Composite Emission Values for each test 

group subject to the emission standards in this table. 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. 2 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). 4 Road Speed Fan. Manufacturers have the option to use a road speed modulated fan as specified in § 86.107–96(d)(1) 

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 will be 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. 56 Vehicle Emission Categories. For MDVs 8,501-10,000 lbs. GVWR, for each model year, the percentage of MDVs 

certified to an SFTP emission category set forth in this section E.1.2.2.3 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 this section 

E.1.2.2.3 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. 

1.2.2.4 SFTP PM Exhaust Emission Standards for Medium-Duty Vehicles. 

The following standards represent the maximum PM composite emission values for the 

full useful life of 2017 and subsequent model-year LEV III LEVs, ULEVs, and SULEVs 

when operating on any the same gaseous or liquid fuel they use for FTP certification. In

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 § 86.107–

96(d)(1) 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.

Standards and Test Procedures for Passenger Cars, Light-Duty Trucks and Medium-Duty Vehicles.” A manufacturer 

must either comply with the NMOG+NOx fleet average requirements for both its PC/LDT1 fleet and its LDT2/MDPV 

fleet or comply with the NMOG fleet average requirements for both its PC/LDT1 fleet and its LDT2/MDPV fleet. A 

manufacturer must calculate its fleet average NMOG+NOx values using the applicable full useful standards.

2.1.1.1 Pooling Provision.

a. For each model year, a manufacturer must demonstrate compliance 

with the fleet average requirements in this section E.2.1.1 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 passenger vehicles that are certified to the California exhaust emission 

standards in section E.1.1, and are produced and delivered for sale in California; or

Option 2: the total number of passenger cars, light-duty trucks, and 

medium-duty passenger vehicles that are certified to the California exhaust emission 

standards in section E.1.1, and are produced and delivered for sale in California, the 

District of Columbia, and all states that have adopted California's exhaust emission 

standards in section E.1.1 for that model year pursuant to section 177 of the federal 

Clean Air Act (42 U.S.C. § 7507).

b. If a manufacturer selects Option 2, that manufacturer must demonstrate 

compliance with sections E.1.1.2.1, E.2.1, E.2.2, E.2.3, and E.2.4 based on Option 2. 

bc. 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.

cd. When a manufacturer is demonstrating compliance using Option 2 for a 

given model year, the term "in California" as used in sections E.2.1.2 and E.3.1 means 

California, the District of Columbia, and all states that have adopted California's exhaust 

emission standards in section E.1.1 for that model year pursuant to Section 177 of the 

federal Clean Air Act (42 U.S.C. § 7507).

de. A manufacturer that selects compliance Option 2 must provide to the 

Executive Officer separate values for the number of vehicles in each test group produced 

and delivered for sale in the District of Columbia and for each individual state within the 

average.

2.1.1.2 PZEVs Anti-Backsliding Requirement. In the 2018 and subsequent 

model years, a manufacturer must produce and deliver for sale in California a minimum 

percentage of its passenger car and light-duty truck fleet that certifies to SULEV30 and 

SULEV20 standards. This minimum percentage must be equal to the average percentage 

of PZEVs produced and deliver for sale in California for that manufacturer based for the 

2015 through 2017 model year. For the 2018 model year, a A manufacturer may

shall be calculated as follows:

(Σ [Number of vehicles in a test group excluding off-vehicle charge capable hybrid electric 

vehicles x applicable emission standard] +

Σ [Number of off-vehicle charge capable hybrid electric vehicles in a test group x 

HEV NMOG+NOx contribution factor]) ÷

Total Number of PCs plus LDT1s Produced and Delivered for sale in California, Including ZEVs 

and HEVs

(b) Each manufacturer's LDT2 and MDPV fleet average NMOG+NOx value 

for the total number of LDT2s and MDPVs produced and delivered for sale in 

California shall be calculated as follows:

(Σ [Number of vehicles in a test group excluding off-vehicle charge capable hybrid electric

2.1.2.2 NMOG+NOx Contribution Factor for Off-vehicle Charge Capable 

HEVs. The HEV NMOG+NOx contribution factor for light-duty off-vehicle charge 

capable hybrid electric vehicles is calculated as follows:

LEV160 HEV Contribution Factor = 0.160 - [(Zero-emission VMT Allowance) x 0.035]

ULEV125 HEV Contribution Factor = 0.125 - [(Zero-emission VMT Allowance) x 0.055]

ULEV70 HEV Contribution Factor = 0.070 - [(Zero-emission VMT Allowance) x 0.020]

ULEV50 HEV Contribution Factor = 0.050 - [(Zero-emission VMT Allowance) x 0.020]

SULEV30 HEV Contribution Factor = 0.030 - [(Zero-emission VMT Allowance) x 0.010]

SULEV20 HEV Contribution Factor = 0.020 - [(Zero-emission VMT Allowance) x 0.020]

where the Zero-emission VMT Allowance for off-vehicle charge capable HEVs is 

determined in accordance with section C.3 of 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 the “California Exhaust Emission Standards and Test Procedures for 2018 

and Subsequent Model Zero-Emission Vehicles and Hybrid Electric Vehicles, in the 

Passenger Car, Light-Duty Truck and Medium-Duty Vehicle Classes.,” as applicable, 

except that for the purposes of this section E.2.1.2.2, the maximum allowable Zeroemission VMT Allowance that may be used in these equations is 1.0. This section 

E.2.1.2.2 shall only apply to off-vehicle charge capable HEVs certified to the LEV III 

standards set forth in section E.1.1.2.

shall use the sum of the corresponding LEV II NMOG and NOx emission category value 

set forth in section E.2.1.2.1(c) of these test procedures for the fleet average calculation. 

If a vehicle is certified to 150,000 mile standards for a federal exhaust emission bin and 

the corresponding California NMOG+NOx emission category is a LEV III category, it 

may use the emission standard value for that LEV III category as set forth in the section 

E.2.1.2 table. 

2.1.3 Phase-in Requirements for Small Volume Manufacturers. 

(a) In the 2015 through 201921 model years, a small volume manufacturer 

shall not exceed a fleet average NMOG+NOx value of 0.160 g/mi for PCs and LDTs 

from 0-3750 lbs. LVW or 0.160 g/mi for LDTs from 3751-5750 lbs. LVW calculated in 

accordance with section E.2.1.2. In 20202 through 2024 model years, a small volume 

manufacturer shall not exceed a fleet average NMOG+NOx value of 0.125 g/mi for PCs 

and LDTs from 0-3750 lbs. LVW or 0.125 g/mi for LDTs from 3751 lbs. LVW - 8,500 

lbs. GVW and MDPVs calculated in accordance with section E.2.1.2. In 2025 and 

subsequent model years, a small volume manufacturer shall not exceed a fleet average

2.2 LEV III Phase-In Requirement for Light-Duty Vehicles and Medium-Duty 

Passenger Vehicles.

For the 2015 and 2016 model years, the LEV II SULEV emission standards set 

forth in section E.1.1.1 that are applicable to PCs, LDTs, and MDPVs shall only apply to 

those PCs, LDT1s, LDT2s, and MDPVs that certify to SULEV emission standards using 

“carryover” of emission test data from a previous model year in accordance with U.S. EPA 

OMS Advisory Circular A/C No. 17F, issued November 16, 1982, and last amended January

2.5.5 Calculation of Fleet Average Carbon Dioxide Value. 

* * * *

2.5.5.4 For each model year, a manufacturer must demonstrate compliance 

with the fleet average requirements in section E.2.5 based on one of two options 

applicable throughout the model year, either:

Option 1: the total number of passenger cars, light-duty trucks, and mediumduty passenger vehicles that are certified to the California exhaust emission standards in 

section E.2.5, and are produced and delivered for sale in California; or

Option 2: the total number of passenger cars, light-duty trucks, and mediumduty passenger vehicles that are certified to the California exhaust emission standards in 

section E.2.5, and are produced and delivered for sale in California, the District of 

Columbia, and all states that have adopted California's greenhouse gas emission 

standards for that model year pursuant to Section 177 of the federal Clean Air Act (42 

U.S.C. § 7507).

1. 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. 

2. When a manufacturer is demonstrating compliance using Option 2 for a 

given model year, the term "in California" as used in sections E.2.5 and E.3.2 means 

California, the District of Columbia, and all states that have adopted California's 

greenhouse gas emission standards for that model year pursuant to Section 177 of the 

federal Clean Air Act (42 U.S.C. § 7507).

3. A manufacturer that selects compliance Option 2 must provide to the 

Executive Officer separate values for the number of vehicles in each model type and 

footprint value produced and delivered for sale in the District of Columbia and for 

each individual state within the average and the City CO2 Value and Highway CO2

exhaust emission values that apply to each model type and footprint value.

2.5.6 Credits for Reduction of Air Conditioning Direct Emissions. 

Manufacturers may generate A/C Direct Emissions Credits by implementing specific air 

conditioning system technologies designed to reduce air conditioning direct emissions over 

the useful life of their vehicles. A manufacturer may only use an A/C Direct Emissions 

Credit for vehicles within a model type upon approval of the A/C Direct Emissions Credit for 

that model type by the Executive Officer. The conditions and requirements for obtaining 

approval of an A/C Direct Emissions Credit are described below.

2.5.6.2 To obtain approval of the A/C Direct Emissions Credit, the manufacturer 

must demonstrate through an engineering evaluation that the A/C system under 

consideration reduces A/C direct emissions. The demonstration must include all of the 

following elements:

• the amount of A/C Direct Emissions Credit requested, in grams of CO2-equivalent per 

mile (gCO2e/mi); 

• the calculations identified in section 1961.3(a)(6)(C) justifying that credit amount, 

• schematic of the A/C system; 

• specifications of the system components with sufficient detail to allow reproduction 

of the calculation; and

• a justification that the number of fittings and joints has been minimized and 

components have been optimized to minimize leakage an explanation describing what 

efforts have been made to minimize the number of fittings and joints and to optimize 

the components in order to minimize leakage. 

Calculated values must be carried to at least three significant figures throughout the 

calculations, and the final credit value must be rounded to one tenth of a gram of CO2-

equivalent per mile (gCO2e/mi).

1.4 Certification of a Federal Vehicle in California. Whenever a manufacturer 

federally-certifies a 2015 or subsequent model-year passenger car, light-duty truck or mediumduty vehicle model to the standards for a particular emissions bin that are more stringent than the 

standards for an applicable California vehicle emissions 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 Tables S04-1 and S04-2 of 40 CFR 

section 86.1811-04(c) as adopted February 10, 2000. A California vehicle model is to be treated 

as equivalent to a federal vehicle model if all of the following characteristics are identical:

(a) Vehicle make and model;

(b) Cylinder block configuration (e.g., L-6, V-8);

(c) Displacement;

(d) Combustion cycle; 

(e) Transmission class;

(f) Aspiration method (e.g., naturally aspirated, turbocharged); and

(g) Fuel (e.g., gasoline, natural gas, methanol).

The comparative stringency of the standards for the federal exhaust emissions bin and for the 

California vehicle emissions category shall be based on a comparison of the sum of the 150,000 

mile federal standards to the LEV III NMOG+NOx standards or the sum of the 120,000 mile 

federal standards to the sum of the 120,000 mile LEV II NMOG and NOx standards, as 

applicable.

1.4.4 For purposes of meeting the California NMOG+NOx fleet average phasein requirements or for determining vehicle equivalent credits, the applicable California 

NMOG+NOx value for passenger cars and light-duty trucks or vehicle equivalent credits for 

medium-duty vehicles shall be determined as follows:

(a) Tthe sum of the federal full useful life (150,000 miles or 120,000 miles, as 

applicable) NMOG and NOx values shall be compared with the next less stringent California 

full useful life NMOG+NOx value to determine which emission category (e.g., LEV630, 

LEV395, LEV160, ULEV570, ULEV400, ULEV340, ULEV270, ULEV250, ULEV200, 

ULEV125, ULEV70, ULEV50, SULEV230, SULEV200, SULEV170, SULEV150, 

SULEV30, or SULEV20) is to be used for the fleet average value or vehicle equivalent credit 

calculation.

(b) For passenger cars and light-duty trucks, once the equivalent California emission 

category is determined (e.g., whether the vehicle is considered a LEV630, LEV395, LEV160, 

ULEV570, ULEV400, ULEV340, ULEV270, ULEV250, ULEV200, ULEV125, ULEV70, 

ULEV50, SULEV230, SULEV200, SULEV170, SULEV150, SULEV30, or SULEV20), the 

applicable NMOG+NOx value to be used in the fleet average calculation is set forth in the 

table in section E.2.1.2 of these test procedures for passenger cars and light-duty trucks. For 

example, if the full useful life (150,000 miles) NMOG plus NOx standard to which the 

federal vehicle is certified is 0.110 grams per mile, that vehicle would be considered a 

ULEV125 for fleet average purposes because the combined ULEV125 full useful life 

NMOG+NOx value is 0.125 and is the next less stringent emission category. The applicable 

emission standard to be used in the fleet average calculation would therefore be 0.125 grams 

per mile.

which the vehicle was deemed certified for fleet average NMOG purposes.

100.5.5 California exhaust emission test procedures for US06 emissions.

100.5.5.1 Amend §86.159-08 as follows: Add the following sentence: The 

exhaust PM emissions shall be measured using equivalent measurement techniques as 

those used to measure exhaust PM emissions on the FTP cycle except that provisions 

accounting for the cold start portion of the FTP cycle (including factors used to weight 

emission values from the different phases) shall be ignored. 

100.5.5.12 Delete subparagraph (b)(9) of §86.159-08 and replace with:

During dynamometer operation, a fixed speed cooling fan or a road speed modulated fan 

as specified in §86.107–96(d)(1) may be used. The fan shall be positioned so as to direct 

cooling air to the vehicle in an appropriate manner. The engine compartment cover shall 

remain open if a fixed speed cooling fan is used and closed if a road speed modulated fan 

is used. In the case of vehicles with front engine compartments, the fan shall be squarely 

positioned within 24 inches (61 centimeters) of the vehicle. In the case of vehicles with 

rear engine compartments (or if special designs make the above impractical), the cooling 

fan shall be placed in a position to provide sufficient air to maintain vehicle cooling. The 

Executive Officer may approve modified cooling configurations or additional cooling if 

necessary to satisfactorily perform the test. In approving requests for additional or 

modified cooling, the Executive Officer will consider such items as actual road cooling 

data and whether such additional cooling is needed to provide a representative test.

formaldehyde emissions shall be measured according to the US06 Test Procedure as set 

forth in Subpart B, 40 CFR 86.159-08 with the following modifications:

1. Replace all references to “US06” with “Hot 1435 Unified Cycle.” Where 

§86.159-08 references another section of 40 CFR part 86, replace all mention of “US06” 

with “Hot 1435 Unified Cycle” in referenced sections. 

2. Amend 40 CFR 86.159-08 as follows:

2.1 Delete Paragraph (a); replace with: Overview. 

The dynamometer operation consists of a single test starting from second 

0 and ending at second 1435 in the driving schedule shown in Part II, Section EG. 

This cycle will herein be referred to as “Hot 1435 Unified Cycle.” The vehicle is 

preconditioned in accordance with the instructions in this section to bring it up to 

a warmed-up, stabilized condition. This preconditioning is followed by a 1 to 2 

minute idle period that proceeds directly into the Hot 1435 Unified Cycle driving 

schedule during which continuous proportional samples of gaseous emissions are 

collected for analysis.

D-2

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

(A) Calculation of Hydrocarbon Credits or Debits. For each emission standard 

category in the model year, a manufacturer shall calculate the hydrocarbon 

credits or debits, as follows:

[(Applicable Hydrocarbon Emission Standard for the Emission Standard 

Category) – (Manufacturer’s Fleet-Average Hydrocarbon Emission Value for the 

Emission Standard Category)] X (Total Number of Affected Vehicles)

where “Total Number of Affected Vehicles” = the total number of vehicles in the 

evaporative families participating in the fleet-average option, which are 

produced and delivered for sale in California, for the emission standard 

category of the given model year.

A negative number constitutes hydrocarbon debits, and a positive number 

constitutes hydrocarbon credits accrued by the manufacturer for the given model 

year. Hydrocarbon credits earned in a given model year shall retain full value 

through the fifth model year after they are earned. At the beginning of the sixth 

model year, the hydrocarbon credits will have no value.

(B) Procedure for Offsetting Hydrocarbon Debits. A manufacturer shall offset 

hydrocarbon debits with hydrocarbon credits for each emission standard 

category within three model years after the debits have been incurred. If total 

hydrocarbon debits are not equalized within three model years after they have 

been incurred, the manufacturer shall be subject to the Health and Safety Code 

section 43211 civil penalties 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 

hydrocarbon 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 shall be determined by dividing

the total amount of hydrocarbon debits for the model year in the emission 

standard category by the applicable hydrocarbon emission standard for the 

model year in which the debits were first incurred.

Additionally, a manufacturer may use the excess hydrocarbon credits from the 

emission standard categories of (1) passenger cars and light-duty trucks 6,000 

pounds GVWR and under, and 0 - 3,750 pounds LVW and (2) light-duty trucks 

6,000 pounds GVWR and under, and 3,751 – 5,750 pounds LVW to equalize the 

hydrocarbon debits that remain at the end of the three model year offset period of 

any emission standard category. to equalize the hydrocarbon debits that remain 

at the end of the three model year offset period: (1) hydrocarbon credits may be 

exchanged between passenger cars and light-duty trucks 6,000 pounds GVWR 

and under and 0-3,750 pounds LVW, and light-duty trucks 6,000 pounds GVWR 

and under and 3,751-5,750 pounds LVW and (2) hydrocarbon 

credits may be exchanged between light-duty trucks 6,001-8,500 pounds GVWR 

and medium-duty passenger vehicles, and medium-duty vehicles and heavy-duty 

vehicles.

Date of Hearing: January 26-27, 2012

(4) Vehicle Canister Bleed Emission. Compliance with the canister bleed emission 

standard shall be determined based on the Bleed Emission Test Procedure 

described in section III.D.12. of these procedures and demonstrated on a 

stabilized canister system. Vehicles with a non-integrated refueling canister-only 

system are exempt from the canister bleed emission standard. 

(ii) Phase-In Schedule. For each model year, a manufacturer 

shall certify, at a minimum, the specified percentage of its vehicle fleet to 

the evaporative emission standards set forth in section I.E.1.(e)(i), 

according to the implementation schedule set forth below. For the 

purpose of this section I.E.1.(e)(ii), the manufacturer's vehicle fleet 

consists of the vehicles produced and delivered for sale by the 

manufacturer in California that are subject to the emission standards in 

section I.E.1.(e)(i). All 2015 through 2022 model motor vehicles that are 

not subject to these standards pursuant to the phase-in schedule shall 

comply with the requirements for 2004 through 2014 model motor 

vehicles, as described in section I.E.1.(d).

Model Years Minimum Percentage of Vehicle Fleet(1)(2) 

2015, 2016, and 2017 Average of vehicles certified to section I.E.1.(c) in 

model years 2012, 2013, and 2014(3)(4)

2018 and 2019 60

2020 and 2021 80

2022 and subsequent 100

(1) For the 2018 through 2022 model years only, a manufacturer may use an 

alternate phase-in schedule to comply with the phase-in requirements. An 

alternate phase-in schedule must achieve equivalent compliance volume by the 

end of the last model year of the scheduled phase-in (2022). The compliance 

volume is the number calculated by multiplying the percent of vehicles (based on 

the manufacturer’s projected sales volume of all vehicles) meeting the new 

requirements in each model year by the number of years implemented prior to 

and including the last model year of the scheduled phase-in, then summing these 

yearly results to determine a cumulative total. The cumulative total of the five 

year (60/60/80/80/100) scheduled phase-in set forth above is calculated as 

follows: (60*5 years) + (60*4 years) + (80*3 years) + (80*2 years) + (100*1 year) 

= 1040. Accordingly, the required cumulative total for any alternate phase-in 

schedule of these emission standards is 1040. The Executive Officer shall 

consider acceptable any alternate phase-in schedule that results in an equal or 

larger cumulative total by the end of the last model year of the scheduled phasein (2022).

(2) Small volume manufacturers are not required to comply with the phase-in 

schedule set forth in this table. Instead, they shall certify 100 percent of their

2022 and subsequent model year vehicle fleet to the evaporative emission 

standards set forth in section I.E.1.(e)(i)(A) or section I.E.1.(e)(i)(B).

(3) The percentage of vehicle fleet averaged across the 2015, 2016, and 2017 

model years shall be used to determine compliance with this requirement.

(3) (4) The minimum percentage required in the 2015, 2016, and 2017 model years is 

determined by averaging the percentage of vehicles certified to the emission 

standards in section I.E.1.(c) in each of the manufacturer’s 2012, 2013, and 2014 

model motor vehicle fleets. For the purpose of calculating this average, a 

manufacturer shall use the percentage of vehicles produced and delivered for 

sale in California for the 2012, and 2013, and 2014 model years, and the 

percentage of projected sales in California for the 2014 model year. A 

manufacturer may calculate this average percentage using the projected sales 

for these model years in lieu of actual sales.

(iii) Carry-Over of 2014 Model-Year Evaporative Families Certified 

to the Zero-Fuel Evaporative Emission Standards. A manufacturer may 

carry over 2014 model motor vehicles certified to the zero-fuel (0.0 grams 

per test) evaporative emission standards set forth in section I.E.1.(c) 

through the 2018 model year and be considered compliant with the 

requirements of section I.E.1.(e). If the manufacturer chooses to 

participate in the fleet-average option for the highest whole vehicle diurnal 

plus hot soak emission standard, the following family emission limits are 

assigned to these evaporative families for the calculation of the 

manufacturer’s fleet-average hydrocarbon emission value.

Vehicle Type

Highest Whole Vehicle Diurnal

and 3,751 – 5,750 lbs. LVW

0.400

Light-Duty Trucks

6,001 - 8,500 lbs. GVWR 0.500

(iv) Pooling Provision. The following pooling provision applies to 

the fleet-average option for the Highest Whole Vehicle Diurnal Plus Hot 

Soak Emission Standard in section I.E.1.(e)(i)(B). and to the phase-in 

requirements in section I.E.1.(e)(iii). 
D-5

results reported shall be computed by summing the adjusted evaporative emission result 

determined for the hot soak test (Mhs) and the highest 24-hour result determined for the 

diurnal breathing loss test (Mdi). The final reported result for the running loss test shall 

be the adjusted emission result (Mrl), expressed on a grams per mile basis.

12. Bleed Emission Test Procedure (BETP)

12.1. Carbon Canister System Stabilization. The carbon canister system shall 

be stabilized to a 4,000-mile test condition using one of the following methods: 

12.1.1. Stabilization on a vehicle. The canister system shall be installed on a 

representative vehicle, and the vehicle shall be driven for 4,000 miles using California 

certification fuel the gasoline set forth in part II., section A.100.3.1.2. of the “California

2015 and Subsequent Model Criteria Pollutant Exhaust Emission Standards and Test 

Procedures and 2017 and Subsequent Model Greenhouse Gas Exhaust Emission

ENCLOSURE G

Summary of 15-Day Changes to Proposed Regulation Order and 

Incorporated Test Procedures

Modifications to the Proposed Regulation Order.

Modifications to § 1900. Definitions.

Subsection (b)(22) Qualifying language has been added to the definition 

of a small volume manufacturer. The new text allows manufacturers that 

meet the 4,500 vehicle sales threshold for a small volume manufacturer, but 

are partially or fully owned by another manufacturer, to still qualify as “small 

volume manufacturers,” if they remain operationally independent from the 

company that owns them. 

Modifications to §1961. Exhaust Emission Standards and Test Procedures 

- 2004 through 2019 and Subsequent Model Passenger Cars, Light-Duty 

Trucks, and Medium-Duty Vehicles.

Subsection (a)(1) This subsection has been revised to allow 2015-2019 MY 

LEV II vehicles to certify to combined NMOG+NOx standards instead of 

separate NMOG and NOx standards.

Subsection (b)(1)(A) This subsection has been revised to allow 

manufacturers to meet an NMOG+NOx fleet average standard rather than an 

NMOG fleet average standard for the 2014 model year.

Modifications to §1961.2. Exhaust Emission Standards and Test 

Procedures - 2015 and Subsequent Model Passenger Cars, Light-Duty 

Trucks, and Medium-Duty Vehicles.

The introduction to this section was modified to allow the Pooling Provision to 

apply to this entire section, rather than to just the fleet average.

Subsection (a)(1) This subsection has been revised to allow 2015-2019 MY 

LEV II vehicles to certify to combined NMOG+NOx standards instead of 

separate NMOG and NOx standards.

Subsection (a)(2) The title of this subsection has been modified.
G-2

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Subsection (a)(2)(B) This subsection has been modified to allow 

manufacturers to meet the phase-in requirements for the LEV III medium-duty 

vehicle particulate standards based on a percentage of the combined sales of 

medium-duty vehicles weighing 8,501 to 10,000 pounds GVWR and mediumduty vehicles weighing 10,001 to 14,000 pounds GVWR, rather than separate 

percentages for the two weight classes.

Subsection (a)(2)(D) This subsection has been modified to provide 

manufacturers with an alternative compliance option for meeting the proposed 

particulate matter standards. 

Subsection (a)(6) The NMOG+NOx standards that are applicable to this 

subsection are given in terms of three decimal places. It is, therefore, 

appropriate to round off the measured emission values to three decimal 

places. However, the current proposed text specifies that the emissions 

values be rounded to two decimal places. This error has been corrected.

Subsection (a)(7)(A) This subsection has been modified to allow early 

compliance with 150,000-mile SFTP standards for model year 2014 vehicles. 

It has also been modified to require LEV III flex-fueled vehicles to test only on 

LEV III certification gasoline. The purpose of this change is to align with the 

LEV III FTP allowance for early compliance for model year 2014 vehicles.

Subsection (a)(7)(A)2 This subsection has been modified to clarify how to 

project full useful life emission values for vehicles continuing to certify to LEV

II SFTP emission standards during the LEV III SFTP phase-in period (“carryover” test groups). It has also been modified to allow the use of full useful life 

SFTP values in lieu of projections if such values are used to certify to the 

4,000-mile emission standards. This has been modified in order to ensure 

clarity for manufacturers and avoid confusion during the certification process.

Subsection (a)(7)(B) This subsection has been modified to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline. The purpose 

of this change is to avoid excessive SFTP testing burden for flex-fueled 

vehicles. It has also been modified to reduce the significant figures of the 

SFTP PM emission standards. This change is being proposed to align the 

PM standards measurement resolution with the current resolution of PM 

measurement equipment

Subsection (a)(7)(C) This subsection has been modified to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline. The purpose 

of this change is to avoid excessive SFTP testing burden for flex-fueled 

vehicles. Also, the naming convention for the UC cycle has been changed to 
G-3

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

“Hot 1435 UC,” to clarify that the required test cycle is a modified UC cycle. 

In addition, the subsection was modified to clarify how to determine 

horsepower for the purposes of the MDV standards and to allow 

manufacturers to use FTP emissions values in place of SC03 emissions 

values in the composite emission equation. The purpose of this change is to 

avoid excessive SFTP testing burden for MDVs. Air conditioning provides a 

relatively small load for an MDV engine and FTP emissions results would be 

similar to SC03 emissions results. 

Subsection (a)(7)(D) This subsection has been modified to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline. The purpose 

of this change is to avoid excessive SFTP testing burden for flex-fueled 

vehicles. It has also been modified to reduce the significant figures of the 

SFTP PM emission standards. This change is being proposed to align the 

PM standards measurement resolution with the current resolution of PM 

measurement equipment. Also, the naming convention for the UC cycle has 

been changed to “Hot 1435 UC,” to clarify that the required test cycle is a 

modified UC cycle.

Subsection (a)(8)(A)1 Three of the values in the table have been corrected 

to align them with the proposed values set forth in the “California 2015 and 

Subsequent Model Criteria Pollutant Exhaust Emission Standards and Test 

Procedures and 2017 and Subsequent Model Greenhouse Gas Exhaust 

Emission Standards and Test Procedures for Passenger Cars, Light-Duty 

Trucks, and Medium-Duty Vehicles.”

Subsection (a)(8)(C)(2) This subsection has been modified to allow interim inuse SFTP emission standards for new certifications through the 2020 model 

year. The purpose of this change is to align with the interim in-use standards 

for LEV III FTP.

Subsection (a)(10) The word “shall” has been changed to “may” to make it 

clear that vehicles that certify to the LEV III SULEV30 or the LEV III SULEV20 

standard are not required to generate partial ZEV credits.

Subsection (b)(1)(A) NMOG+NOx fleet average standards have been

added to the table for the 2014 model year, to provide an alternative to the 

NMOG fleet average standards in section 1961.

Subsection (b)(1)(A)1 Text from this subsection has been moved to the 

Introduction to this section to show that it applies to the entire section. 

Clarifying language has also been added.
G-4

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Subsection (b)(1)(A)2 This subsection has been modified to allow 

manufacturers to use projected sales data rather than actual sales data to 

determine the minimum number of SULEV30 and SULEV20 vehicles they 

must produce in the 2018 and subsequent model years.

Subsection (b)(1)(B)1.a An error in the formula has been corrected.

Subsection (b)(1)(B)1.b Errors in the formula have been corrected.

Subsection (b)(1)(B)1.c The table has been modified to allow vehicles 

certified to federal standards to be included in the fleet average NMOG+NOx 

calculation based on the actual standards to which they certify. Also, values 

have been added to the table for LEV II LEV ULEV medium-duty vehicles.

Subsection (b)(1)(B)2 This subsection has been amended to correct an 

error in the Zero-emission VMT Allowance values that may be used in the 

calculations.

Subsection (b)(1)(B)3 This subsection has been deleted, because it is no 

longer needed, due to the modifications to subsection (b)(1)(B)1.c.

Subsection (b)(1)(C)1 This subsection has been modified to provide an 

additional two year lead time before small volume manufacturers are required 

to certify to ULEV125 standards. This change aligns the compliance dates for 

certifying to these new standards with the compliance dates by which these 

manufacturers must certify to the 3 mg/mi particulate standards and by which 

they must certify 100 percent of their fleet to LEV III standards.

Subsection (b)(2) This subsection has been modified to allow 

manufacturers to carryover the certification of vehicles that were certified as 

LEV II SULEVs prior to the 2015 model year for the 2015 and 2016 model 

years. This change was needed to accommodate manufacturers’ production 

plans that are already in place. This subsection has also been modified to 

provide small volume manufacturers with an additional two years of lead time 

before they must certify all their vehicles to LEV III standards. This change 

was needed to align their requirement for 100% certification of LEV III 

vehicles with the year that they must meet a more stringent fleet average and 

more stringent particulate matter standards.

Subsection (b)(3)(A) Unnecessary text has been removed.

Subsection (b)(3)(C) It was necessary to add this subsection to the 

regulations to provide an alternate phase-in schedule of LEV III vehicles for 
G-5

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

those manufacturers that produce too few medium-duty vehicle test groups to 

be able to meet the percent requirements for the phase-in of LEV III vehicles.

Subsection (c)(2)(A) The year of applicability for this section has been 

corrected to align it with the year that the LEV III regulations will apply to 

medium-duty vehicles. The first term, which applies to vehicles certified to 

LEV standards, was inadvertently omitted. It has been added back in to the 

formula. The multiplying factors have been corrected to two decimal places 

to make the formulas more accurate. Also, other errors in the formulas have 

been corrected.

Subsection (c)(2)(B) This subsection has been amended to correct an 

error in the Zero-emission VMT Allowance values that may be used in the 

calculations. Also, the formulas that apply to vehicles certified to LEV 

standards were inadvertently omitted. These have been added back in. 

Subsection (f) This new subsection adds a severability provision to section 

1961.2. 

Modifications to §1961.3. Greenhouse Gas Exhaust Emission Standards 

and Test Procedures - 2017 and Subsequent Model Passenger Cars, LightDuty Trucks, and Medium-Duty Vehicles.

Subsection (a)(5)(D)1 This subsection has been modified to eliminate the 

requirement that a manufacturer that elects to pool its emissions report that 

selection to ARB prior to the start of each model year to which that selection 

applies.

Subsection (a)(5)(D)3 This subsection has been modified to add clarifying 

language.

Subsection (a)(6)(B) The last bullet in this subsection is meant to be a 

reporting requirement that an A/C Direct Emissions Credit application must 

meet, instead of one of the criteria that an A/C system must meet in order to 

qualify for A/C Direct Emissions Credit. However, this was unclear to 

manufacturers based on 45-day comments received by ARB. Consequently, 

this subsection has been revised to clarify the intent of the language. 

Subsection (a)(10) The in-use compliance standards for vehicles 

certifying to the greenhouse gas standards in this section were inadvertently 

omitted from the regulations. They have been added to the regulations.
G-6

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Modifications to §1976. Standards and Test Procedures for Motor Vehicle 

Fuel Evaporative Emissions.

Subsection (b)(1)(G)1.b This subsection has been modified to revise the 

provisions for trading evaporative emission fleet-average credits among 

certain vehicle categories. This change would provide additional flexibility for 

trading evaporative emission credits among the heavier vehicle categories. 

Staff believes that this change will not compromise manufacturers’ 

requirement to implement effective evaporative control across the entire fleet.

Subsection (b)(1)(G)2 This subsection has been modified to allow 

manufacturers to use projected sales data rather than actual sales data to 

determine the minimum number of vehicles they must produce in the 2015-

2017 model years that meet the proposed evaporative emission standards. 

This subsection has also been modified to base compliance for this 

requirement upon the average number of vehicles produced over the 2015-

2017 time period in lieu of a year-by-year requirement. These modifications 

would provide flexibility in response to industry requests without 

compromising the requirement for manufacturers to maintain the percentage 

of zero-evaporative vehicles in their fleet during the early years of the phasein to the proposed standards.

Subsection (b)(1)(G)4 This subsection has been revised to modify the 

pooling compliance option concerning states that adopt California’s 

evaporative emission standards pursuant to section 177 of the federal Clean 

Air Act (42 U.S.C. § 7507) to specifically set forth required submittal 

information and to reduce the Executive Officer notification requirement.

These changes are being proposed to clarify the information required and 

reduce the compliance burden for manufacturers who choose the pooling 

option.

Subsection (b)(1)(G)5 This subsection has been revised to allow optional 

early compliance in the 2014 model year with the proposed evaporative 

emission standards. This change is being proposed to provide additional 

flexibility to vehicle manufacturers.

Modifications to §1978. Standards and Test Procedures for Vehicle 

Refueling Emissions.

Revise exemption for incomplete medium-duty vehicles.

It has been suggested that all incomplete vehicles, rather than just a subset of 

incomplete vehicles, be exempted from the refueling requirements given the 
G-7

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

added complexity that testing refueling on incomplete vehicles entails. Staff 

agrees and proposes a modification to reflect this. 

Modifications to §2112. Definitions.

A reference to new section §1961.3 was inadvertently omitted from this

Date of Hearing: January 26-27, 2012

Summary of 15-Day Changes to “California 2001 through 2014 Model 

Criteria Pollutant Exhaust Emission Standards and Test Procedures and 

2009 through 2016 Model Greenhouse Gas Exhaust Emission Standards 

and Test Procedures for Passenger Cars, Light Duty Trucks and Medium 

Duty Vehicles”

Part I. Subpart D

Subsection 2.1.4 This subsection has been revised to require the air to fuel 

ratio to not be richer than the leanest air to fuel mixture required to obtain 

maximum torque (lean best torque), with a tolerance of six percent of the fuel 

consumption and remove a provision describing the operating mode of the 

emission control system. This change is being proposed because there was 

insufficient time to conduct the necessary testing to ensure that the three 

percent tolerance in air-to-fuel ratio measurement is feasible.

Part I. Subpart E

Subsection 2.1.1 This subsection has been revised to allow manufacturers 

to meet an NMOG+NOx fleet average standard rather than an NMOG fleet 

average standard for the 2014 model year.

Part I. Subpart H

Subsection H.3.2 It is necessary to ask automakers who will be making 

hydrogen fuel cell vehicles to notify ARB of their intent 33 month prior to the 

applicable model year, because this lead time is needed to build a hydrogen 

fueling stations. Although this requirement was included in the proposed 

“California 2015 and Subsequent Model Criteria Pollutant Exhaust Emission 

Standards and Test Procedures and 2017 and Subsequent Model 

Greenhouse Gas Exhaust Emission Standards and Test Procedures for 

Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles,” it was 

inadvertently omitted from these test procedures. This subsection has been 

revised to incorporate these requirements into these test procedures. Also, a 

sentence was added to ensure that we are able to collect hydrogen vehicle 

data three years out starting in 2012, since automakers are planning their 

commercial launch of fuel cell vehicles in 2015. The current proposed 

regulation requires hydrogen vehicle reporting by April 1, so the regulation, as 

currently proposed, will not be chaptered in time to get data that could 

indicate that we trigger the regulation for stations in 2015.

Summary of 15-Day Changes to “California 2015 and Subsequent Model 

Criteria Pollutant Exhaust Emission Standards and Test Procedures and 

2017 and Subsequent Model Greenhouse Gas Exhaust Emission Standards 

and Test Procedures for Passenger Cars, Light-Duty Trucks, and

Medium-Duty Vehicles”

Part I. Subpart B

Subsection B.2. Qualifying language has been added to the definition of a 

small volume manufacturer. The new text allows manufacturers that meet the 

4,500 vehicle sales threshold for a small volume manufacturer, but are 

partially or fully owned by another manufacturer, to still qualify as “small 

volume manufacturers,” if they remain operationally independent from the 

company that owns them. 

Part I. Subpart D

Subsection 2.1.4 This subsection has been revised to require the air to fuel 

ratio to not be richer than the leanest air to fuel mixture required to obtain 

maximum torque (lean best torque), with a tolerance of six percent of the fuel 

consumption and remove a provision describing the operating mode of the 

emission control system. This change is being proposed because there was 

insufficient time to conduct the necessary testing to ensure that the three 

percent tolerance in air-to-fuel ratio measurement is feasible.

Subsection D.2.1.6 This subsection has been revised to remove Small 

Volume Provisions specific to SFTP because the provisions for Small Volume 

Manufacturers already in the LEV III FTP program are linked to the SFTP 

program. 

Subsection D.2.2 This subsection has been revised to specify a conversion 

factor of 1.03 to convert NMHC emission values to NMOG emission values 

for the purpose of determining SFTP compliance. The purpose of this change 

is to provide an accurate conversion factor for the US06 cycle because LEV II 

SFTP testing only required measurement of NMHC emission values. 

Part I. Subpart E

Subsection E.1.1.1 This subsection has been revised to allow 2015-2019 

MY LEV II vehicles to certify to combined NMOG+NOx standards instead of 

separate NMOG and NOx standards.

Subsection E.1.1.2.1 The title of this subsection has been modified.
G-10

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Subsection E.1.1.2.1.2 This subsection has been modified to allow 

manufacturers to meet the phase-in requirements for the LEV III medium-duty 

vehicle particulate standards based on a percentage of the combined sales of 

medium-duty vehicles weighing 8,501 to 10,000 pounds GVWR and mediumduty vehicles weighing 10,001 to 14,000 pounds GVWR, rather than separate 

percentages for the two weight classes.

Subsection E.1.1.2.1.4 This subsection has been modified to provide 

manufacturers with an alternative compliance option for meeting the proposed 

particulate matter standards. 

Subsection E.1.2.2.1 This subsection has been revised to allow early 

compliance with 150,000-mile SFTP standards for model year 2014 vehicles. 

The purpose of this change is to align with the LEV III FTP allowance for early 

compliance for model year 2014 vehicles.

Subsection E.1.2.2.1.1 This subsection has been revised to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline for SFTP 

certification. The purpose of this change is to avoid excessive SFTP testing 

burden for flex-fueled vehicles. The table has been corrected to specify that 

the standards are NMOG-based standards and not NMHC-based standards. 

This has been changed to correct a clerical error. 

Subsection E.1.2.2.1.2 This subsection has been revised to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline for SFTP 

certification. The purpose of this change is to avoid excessive SFTP testing 

burden for flex-fueled vehicles. 

Subsection E.1.2.2.1.2 Footnote 2 of the table has been revised to clarify 

how to project full useful life emission values for vehicles continuing to certify 

to LEV II during the LEV III phase-in period (“carry-over” test groups). It has 

also been modified to allow the use of full useful life SFTP values in lieu of 

projections if such values are used to certify to the 4,000-mile emission 

standards. This has been modified in order to ensure clarity for 

manufacturers and avoid confusion during the certification process.

Subsection E.1.2.2.2 This subsection has been revised to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline for SFTP 

certification. The purpose of this change is to avoid excessive SFTP testing 

burden for flex-fueled vehicles. It has also been modified to reduce the 

significant figures of the SFTP PM emission standards. This change is being 

proposed to align the PM standards resolution with the current resolution of 

PM measurement equipment.
G-11

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Subsection E.1.2.2.3 This subsection has been revised to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline for SFTP 

certification. The purpose of this change is to avoid excessive SFTP testing 

burden for flex-fueled vehicles. Also, the naming convention for the UC cycle 

has been changed to “Hot 1435 UC,” to clarify that the required test cycle is a 

modified UC cycle. In addition, the subsection was modified to clarify how to 

determine horsepower for the purposes of the MDV standards and to allow 

manufacturers to use FTP emissions values in place of SC03 emissions 

values in the composite emission equation. The purpose of this change is to 

avoid excessive SFTP testing burden for MDVs. Air conditioning provides a 

relatively small load for an MDV engine and FTP emissions results would be 

similar to SC03 emissions results. 

Subsection E.1.2.2.4 This subsection has been revised to require LEV III 

flex-fueled vehicles to test only on LEV III certification gasoline for SFTP 

certification. The purpose of this change is to avoid excessive SFTP testing 

burden for flex-fueled vehicles. Also, the naming convention for the UC cycle 

has been changed to “Hot 1435 UC,” to clarify that the required test cycle is a 

modified UC cycle. It has also been modified to reduce the significant figures 

of the SFTP PM emission standards. This change is being proposed to align 

the PM standards resolution with the current resolution of PM measurement 

equipment.

Subsection E.1.6 The NMOG+NOx standards that are applicable to this 

subsection are given in terms of three decimal places. It is, therefore, 

appropriate to round off the measured emission values to three decimal 

places. However, the current proposed text specifies that the emissions 

values be rounded to two decimal places. This error has been corrected.

Subsection E.1.8 The word “shall” has been changed to “may” to make it 

clear that vehicles that certify to the LEV III SULEV30 or the LEV III SULEV20 

standard are not required to generate partial ZEV credits.

Subsection E.2.1.1 NMOG+NOx fleet average standards have been

added to the table for the 2014 model year, to provide an alternative to the 

NMOG fleet average standards in the “California 2001 through 2014 Model 

Criteria Pollutant Exhaust Emission Standards and Test Procedures and 2009 

through 2016 Model Greenhouse Gas Exhaust Emission Standards and Test 

Procedures for Passenger Cars, Light Duty Trucks and Medium Duty 

Vehicles.”
G-12

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Subsection E.2.1.1.1 Text has been added to this subsection to extend the 

pooling provision to other sections of these test procedures that address the 

phase-in of LEV III standards.

Subsection E.2.1.1.2 This subsection has been modified to allow 

manufacturers to use projected sales data rather than actual sales data to 

determine the minimum number of SULEV30 and SULEV20 vehicles they 

must produce in the 2018 and subsequent model years.

Subsection E.2.1.2.1(a) and (b) Errors in the formulas have been corrected.

Subsection E.2.1.2.1(c) The table has been modified to allow vehicles 

certified to federal standards to be included in the fleet average NMOG+NOx 

calculation based on the actual standards to which they certify. Also, values 

have been added to the table for LEV II LEV ULEV medium-duty vehicles.

Subsection E.2.1.2.2 This subsection has been amended to correct an 

error in the Zero-emission VMT Allowance values that may be used in the 

calculations.

Subsection E.2.1.2.3 This subsection has been deleted, because it is no 

longer needed, due to the modifications to subsection E.2.1.2.2.

Subsection E.2.1.3 This subsection has been modified to provide an 

additional two year lead time before small volume manufacturers are required 

to certify to ULEV125 standards. This change aligns the compliance dates for 

certifying to these new standards with the compliance dates by which these 

manufacturers must certify to the 3 mg/mi particulate standards and by which 

they must certify 100 percent of their fleet to LEV III standards.

Subsection E.2.2 This subsection has been modified to allow 

manufacturers to carryover the certification of vehicles that were certified as 

LEV II SULEVs prior to the 2015 model year for the 2015 and 2016 model 

years. This change was needed to accommodate manufacturers’ production 

plans that are already in place. This subsection has also been modified to 

provide small volume manufacturers with an additional two years of lead time 

before they must certify all their vehicles to LEV III standards. This change 

was needed to align their requirement for 100% certification of LEV III 

vehicles with the year that they must meet a more stringent fleet average and 

more stringent particulate matter standards.

Subsection E.2.3.1(a) Unnecessary text has been removed.
G-13

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Subsection E.2.3.1(c) It was necessary to add this subsection to the 

regulations to provide an alternate phase-in schedule of LEV III vehicles for 

those manufacturers that produce too few medium-duty vehicle test groups to 

be able to meet the percent requirements for the phase-in of LEV III vehicles.

Subsection E.2.5.5.4.1 This subsection has been modified to eliminate the 

requirement that a manufacturer that elects to pool its emissions report that 

selection to ARB prior to the start of each model year to which that selection 

applies.

Subsection E.2.5.5.4.3 This subsection has been modified to add clarifying 

language.

Subsection E.2.5.6.2 The last bullet in this subsection is meant to be a 

reporting requirement that an A/C Direct Emissions Credit application must 

meet, instead of one of the criteria that an A/C system must meet in order to 

qualify for A/C Direct Emissions Credit. However, this was unclear to 

manufacturers based on 45-day comments received by ARB. Consequently, 

this subsection has been revised to clarify the intent of the language. 

Subsection E.3.1.2.1 The year of applicability for this section has been 

corrected to align it with the year that the LEV III regulations will apply to 

medium-duty vehicles. The first term, which applies to vehicles certified to 

LEV standards, was inadvertently omitted. The multiplying factors have been 

corrected to two decimal places to make the formulas more accurate. These 

have been added back in. Also, other errors in the formulas have been 

corrected.

Subsection E.3.1.2.2 This subsection has been amended to correct an 

error in the Zero-emission VMT Allowance values that may be used in the 

calculations. Also, the formulas that apply to vehicles certified to LEV 

standards were inadvertently omitted. These have been added back in.

Subsection E.4.3.2 This subsection has been revised to allow interim inuse SFTP emission standards for new certifications through the 2020 model 

year. The purpose of this change is to align with the interim in-use standards 

year for LEV III FTP.

Subsection E.5 The in-use compliance standards for vehicles certifying to 

the greenhouse gas standards in this section were inadvertently omitted from 

these test procedures. They have been added in. 
G-14

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Part I. Subpart G

Subsection G.3.5 Testing requirements for demonstration of compliance 

with the LEV III PM standards have been added. 

Part I. Subpart H

Subsection H.1.4(g) Text was inadvertently omitted from this subsection that 

sets forth criteria for comparing the stringency of LEV II standards and federal 

Tier 2 standards. The modifications to this subsection are needed to correct 

that omission.

Subsection H.1.4.4 Subsection E.2.1.2.1(c) has been revised to require that 

federally-certified vehicles be included in a manufacturer’s fleet average 

NMOG+NOx emission calculation based on the sum of the federal full useful 

life NMOG and NOx standards to which the vehicles certify. This change 

makes the text in H.1.4.4(a) and H.1.4.4(b) unnecessary. Therefore, this 

subsection was revised to remove text that is no longer needed. It was also 

necessary to add text to this subsection to accurately reflect that some 

vehicles certified under these test procedures must meet 120,000 mile full 

useful life standards. The originally proposed language erroneously implies 

that all vehicles subject to this subsection are certified to 150,000 mile full 

useful life standards. 

Subsection H.1.4.6 This subsection was revised to reference the correct 

title of the applicable document.

Subsection H.3.2 “Vehicle fuel pressure rating” was added to the reporting 

requirement for hydrogen vehicles to inform us about the fueling requirements 

of the cars so that we can best inform the regulated party about fuel 

dispenser specs.

Subsection H.4.1.3(b) A typo has been corrected.

Part II. Subpart A

Subsection 100.3.1.2 Errors in the footnotes in the table have been 

corrected.

Subsection 100.3.4 This subsection has been revised to require the use 

of the proposed test fuel containing ten percent ethanol for evaporative 

emission testing of flex fuel vehicles. Automobile manufacturers requested 

this change to reduce the number of different test fuels that would need to be 

maintained in order to complete certification testing. Staff agrees that this 
G-15

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

change is needed and staff does not believe it would reduce the benefit of the 

proposed evaporative emission program.

Subsection 100.5.5.1 This subsection has been modified to clarify how to 

measure PM exhaust emissions on SFTP cycles.

Subsection 100.5.5.2 This subsection has been revised to allow use of a 

road-speed modulated fan in place of a fixed speed fan on the US06 cycle. 

The purpose of this change is to provide a more accurate simulation of real 

driving conditions.

Subsection 100.5.5.2.2.2 has been revised to specify that the engine 

compartment shall remain closed if a road-speed modulated fan is used. The 

purpose of this change is to require proper lab usage of road-speed 

modulated fans. 

Subsection 100.5.5.3 This subsection has been modified to clarify how to 

measure PM exhaust emissions on SFTP cycles. It has also been revised to 

define the “Hot 1435 Unified Cycle” test for clarity. 

Subsection 100.5.5.4.2.2.2 This subsection has been modified to clarify how 

to measure PM exhaust emissions on SFTP cycles. It has also been revised 

to specify that the engine compartment shall remain closed if a road-speed 

modulated fan is used. The purpose of this change is to require proper lab 

usage of road-speed modulated fans.

Part II. Subpart G

This section has been added to specify the speed vs. time sequence for the 

Hot 1435 Unified Cycle Driving Schedule.

Summary of 15-Day Changes to “California Evaporative Emission 

Standards and Test Procedures for 2001 and Subsequent Model Motor 

Vehicles”

Part I. Subpart E

Subsection 1.(e)(i)(B) This subsection has been modified to revise the 

provisions for trading evaporative emission fleet-average credits among 

certain vehicle categories. This change would provide additional flexibility for 

trading evaporative emission credits among the heavier vehicle categories. 
G-16

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

Staff believes that this change will not compromise manufacturers’ 

requirement to implement effective evaporative control across the entire fleet.

Subsection 1.(e)(ii) This subsection has been modified to allow 

manufacturers to use projected sales data rather than actual sales data to 

determine the minimum number of vehicles they must produce in the 2015-

2017 model years that meet the proposed evaporative emission standards. 

This subsection has also been modified to base compliance for this 

requirement upon the average number of vehicles produced over the 2015-

2017 time period in lieu of a year-by-year requirement. These modifications 

would provide flexibility in response to industry requests without 

compromising the requirement for manufacturers to maintain the percentage 

of zero-evaporative vehicles in their fleet during the early years of the phasein to the proposed standards.

Subsection 1.(e)(iv) This subsection has been modified to add a provision 

for the pooling compliance option concerning states that adopt California’s 

evaporative emission standards pursuant to section 177 of the federal Clean 

Air Act (42 U.S.C. § 7507). This change is being added since staff 

inadvertently omitted the pooling provision from the 45-day document. This 

provision matches the 15-day amended language in §1976. Standards and 

Test Procedures for Motor Vehicle Fuel Evaporative Emissions, Subsection 

(b)(1)(G)4.

Subsections 1.(e)(v) This subsection has been revised to allow optional 

early compliance in the 2014 model year with the proposed evaporative 

emission standards. This change is being proposed to provide additional 

flexibility to vehicle manufacturers.

Part III. Subpart D

Subsections 1.1, 10.1, 10.15, and 11 These subsections have been 

revised to provide equations and instructions for evaporative testing with the 

proposed certification test fuel containing ten percent ethanol.

Subsection 11.3.1 This subsection has been revised to add an optional 

hydrocarbon mass adjustment factor for ethanol in lieu of directly measuring 

ethanol emissions. The purpose of this change is to reduce equipment 

requirements and test burden when testing with the proposed E10 fuel.

Subsection 12 This subsection has been modified to allow air to be mixed 

with fuel vapor for canister stabilization in the bleed emission test procedure 

and to specifically set forth a requirement to use the proposed ethanol-
G-17

Date of Release: February 22, 2012; Proposed 15-day Changes

Date of Hearing: January 26-27, 2012

containing certification fuel for this test. The purpose of this proposed change 

is to reduce test burden and to clarify the fuel requirement for this test.

Part III. Subpart F

Subsection 2 This subsection has been revised to require the use of the 

new certification fuel containing ten percent ethanol for vehicles that comply 

with the proposed evaporative emission standards in the 2014 model year

and to clarify the proposed evaporative emission test fuel requirement and 

implementation date for gasoline-fueled vehicles.

Subsection 3 This subsection has been revised to clarify the evaporative 

emission test fuel requirement for alternative-fueled (including flex fuel) 

vehicles. 

Summary of 15-Day Changes to “California Refueling Emission Standards 

and Test Procedures for 2001 and Subsequent Model Motor Vehicles”

Subpart S, Subsections I.A.1, I.F.2, and I.F.2.3 It has been suggested that 

all incomplete vehicles, rather than just a subset of incomplete vehicles, be 

exempted from the refueling requirements given the added complexity that 

testing refueling on incomplete vehicles entails. Staff agrees and proposes 

these modifications to reflect this change. 

Summary of 15-Day Changes to “California Test Procedures for Evaluating

Substitute Fuels and New Clean Fuels in 2015 and Subsequent Years”
