							 loss and useful life standards shall be based on the manufacturer's projected
							 California model-year sales (a) of passenger cars and (b) of light-duty trucks,
							 medium-duty vehicles and heavy-duty vehicles. Optionally, the percentage of
							 motor vehicles can also be based on the manufacturer's projected California
							 model-year sales (a) of passenger cars and light-duty trucks and (b) of
							 medium-duty vehicles and heavy-duty vehicles.
Beginning with the 1998 model year, all
							 motor vehicles subject to the running loss and useful life standards, except
							 those produced by ultra-small volume manufacturers, shall be certified to the
							 specified standards. In the 1999 through 2005 model years, all motor vehicles
							 subject to the running loss and useful life standards, including those produced
							 by ultra-small volume manufacturers, shall be certified to the specified
							 standards.
All 1995 through 1998 model-year motor
							 vehicles which are not subject to running loss and useful life standards
							 pursuant to the phase-in schedule shall comply with the 50,000-mile standards
							 in effect for 1980 through 1994 model-year vehicles.
4 For the 1995 model year only,
					 the evaporative emission standards for complete vehicles in this weight range
					 shall be 2.0 grams/test and compliance with the evaporative emission standards
					 shall be based on the SHED conducted in accordance with the procedures set
					 forth in Title 40, Code of Federal Regulations, sections
					 86.130-78 through
					 86.143-90 as they existed July 1,
					 1989. For the 1995 through 2005 model years, the evaporative emission standards
					 for incomplete vehicles in this weight range shall be 2.0 grams/test and
					 compliance with the evaporative emission standards shall be based on the test
					 procedures specified in paragraph 4.g. of the "California Evaporative Emission
					 Standards and Test Procedures for 1978 and Subsequent Model Motor
					 Vehicles."
5 The running loss and useful
					 life standards for all hybrid electric vehicles shall be effective beginning in

					 Regulations. Approval of vehicles which are not exhaust emission tested using a
					 chassis dynamometer pursuant to section
					 1960.1 or
					 1961, Title 13, California Code of
					 Regulations shall be based on an engineering evaluation of the system and data
					 submitted by the applicant.
3 The two-day diurnal plus hot
					 soak evaporative emission standards (hereinafter "supplemental standards")
					 shall be phased-in beginning with the 1996 model year. Those vehicles certified
					 under the running loss and useful life standards for the 1996 through 2005
					 model years must also be certified under the supplemental
					 standards.
(D) Zero-emission
				  vehicles shall produce zero fuel evaporative emissions under any and all
				  possible operational modes and conditions.
(E) For 2001 through 2014 model year
				  vehicles, the optional zero-fuel evaporative emission standards for the
				  three-day and two-day diurnal-plus-hot-soak tests are 0.35 grams per test for
				  passenger cars, 0.50 grams per test for light-duty trucks 6,000 lbs. GVWR and
				  under, and 0.75 grams per test for light-duty trucks from 6,001 to 8,500 lbs.
				  GVWR, to account for vehicle non-fuel evaporative emissions (resulting from
				  paints, upholstery, tires, and other vehicle sources). Vehicles demonstrating
				  compliance with these evaporative emission standards shall also have zero (0.0)
				  grams of fuel evaporative emissions per test for the three-day and two-day
				  diurnal-plus-hot-soak tests. The "useful life" shall be 15 years or 150,000
				  miles, whichever occurs first. In lieu of demonstrating compliance with the
				  zero (0.0) grams of fuel evaporative emissions per test over the three-day and
				  two-day diurnal-plus-hot-soak tests, the manufacturer may submit for advance
				  Executive Officer approval a test plan to demonstrate that the vehicle has zero
				  (0.0) grams of fuel evaporative emissions throughout its useful life.
Additionally, in the case of a SULEV vehicle for which a
					 manufacturer is seeking a partial ZEV credit, the manufacturer may prior to
					 certification elect to have measured fuel evaporative emissions reduced by a
					 specified value in all certification and in-use testing of the vehicle as long
					 as measured mass exhaust emissions of NMOG for the vehicle are increased in all
					 certification and in-use testing. The measured fuel evaporative emissions shall
					 be reduced in increments of 0.1 gram per test, and the measured mass exhaust
					 emissions of NMOG from the vehicle shall be increased by a gram per mile
					 factor, to be determined by the Executive Officer, for every 0.1 gram per test
					 by which the measured fuel evaporative emissions are reduced. For the purpose
					 of this calculation, the evaporative emissions shall be measured, in grams per
					 test, to a minimum of three significant figures.
(F) For the 2004 through 2014 model motor
				  vehicles identified below, tested in accordance with the test procedures
				  described in Title 40, Code of Federal Regulations, sections
				  86.130-78 through
				  86.143-90 as they existed July 1,
				  1989 and as modified by the "California Evaporative Emission Standards and Test

(a) These evaporative emission standards
				  shall be phased-in beginning with the 2004 model year. Each manufacturer,
				  except small volume manufacturers, shall certify at a minimum the specified
				  percentage of its vehicle fleet to the evaporative emission standards in this
				  table or the optional zero-evaporative emission standards in section
				  1976(b)(1)(E)
				  according to the schedule set forth below. For purposes of this paragraph (a),
				  each manufacturer's vehicle fleet consists of the total projected California
				  sales of the manufacturer's gasoline-fueled, liquefied petroleum-fueled and
				  alcohol-fueled passenger cars, light-duty trucks, medium-duty vehicles, and
				  heavy-duty vehicles.

A small volume manufacturer shall certify 100 percent of
					 its 2006 and subsequent model vehicle fleet to the evaporative emission
					 standards in the table or the optional zero-evaporative emission standards in
					 section 1976(b)(1)(E).
All 2004 through 2005 model-year motor vehicles which are
					 not subject to these standards or the standards in section
					 1976(b)(1)(E)
					 pursuant to the phase-in schedule shall comply with the requirements of
					 sections 1976(b)(1)(B) and
					 (C).
(b) A manufacturer may use an "Alternative or
				  Equivalent Phase-in Schedule" to comply with the phase-in requirements. An
				  "Alternative Phase-in" is one that achieves at least equivalent emission
				  reductions by the end of the last model year of the scheduled phase-in.
				  Model-year emission reductions shall be calculated by multiplying the percent
				  of vehicles (based on the manufacturer's projected California sales volume of
				  the applicable vehicle fleet) meeting the new requirements per model year by
				  the number of model years implemented prior to and including the last model
				  year of the scheduled phase-in. The "cumulative total" is the summation of the
				  model-year emission reductions (e.g., the three model-year 40/80/100 percent
				  phase-in schedule would be calculated as: (40%*3 years) + (80%*2 years) +
				  (100%*1 year)=380). The required cumulative total for the phase-in of these
				  standards is 380 emission reductions. Any alternative phase-in that results in
				  an equal or larger cumulative total than the required cumulative total by the
				  end of the last model year of the scheduled phase-in shall be considered
				  acceptable by the Executive Officer only if all vehicles subject to the
				  phase-in comply with the respective requirements in the last model year of the
				  required phase-in schedule. A manufacturer shall be allowed to include vehicles
				  introduced before the first model year of the scheduled phase-in (e.g., in the
				  previous example, 10 percent introduced one year before the scheduled phase-in
				  begins would be calculated as: (10%*4 years)=40) and added to the cumulative
				  total.
(c) These evaporative
				  emission standards do not apply to zero-emission vehicles.
4 In-use compliance whole
					 vehicle testing shall not begin until the motor vehicle is at least one year
					 from the production date and has accumulated a minimum of 10,000 miles. For
					 vehicles introduced prior to the 2007 model year, in-use compliance standards
					 of 1.75 times the "Three-Day Diurnal + Hot-Soak" and "Two-Day Diurnal +
					 Hot-Soak" gram per test standards shall apply for only the first three model
					 years of an evaporative family certified to a new
					 standard.
(G) For
				  2015 and subsequent model motor vehicles, the following evaporative emission
				  requirements apply:
1. A manufacturer must
				  certify all vehicles subject to this section to the emission standards
				  specified in either Option 1 or Option 2 below.

b.
Option 2.
The evaporative emissions from 2015 and subsequent
				  model motor vehicles, tested in accordance with the test procedure sequence

2 Except as provided below, for
					 all vehicles certified to these standards, the "useful life" shall be 15 years
					 or 150,000 miles, whichever occurs first. For 2016 and previous model vehicles,
					 2017 and previous model vehicles >6,000 lbs. GVWR, and 2021 and previous
					 model vehicles certified by a small volume manufacturer, the canister bleed
					 standards are certification standards only. Manufacturers are not required to
					 establish deterioration factors for canister bleed emissions. Approval of
					 vehicles that are not exhaust emission tested using a chassis dynamometer
					 pursuant to section
					 1961, title 13, California Code of
					 Regulations shall be based on an engineering evaluation of the system and data
					 submitted by the applicant.
3 The manufacturer shall
					 determine compliance by selecting the highest whole vehicle diurnal plus hot
					 soak emission value of the Three-Day Diurnal Plus Hot Soak Test and of the
					 Two-Day Diurnal Plus Hot Soak Test.
4
Fleet-Average Option
					 for the Highest Whole Vehicle Diurnal Plus Hot Soak Emission Standard Within
					 Each Emission Standard Category.
A manufacturer may optionally comply
					 with the highest whole vehicle diurnal plus hot soak emission standards by
					 using fleet-average hydrocarbon emission values. To participate, a manufacturer
					 must utilize the fleet-average option for all of its emission standard
					 categories and calculate a separate fleet-average hydrocarbon emission value
					 for each emission standard category. The emission standard categories are as
					 follows:
(1) passenger cars and
				  light-duty trucks 6,000 pounds GVWR and under, and 0-3,750 pounds
				  LVW;
(2)  light-duty trucks 6,000
				  pounds GVWR and under, and 3,751-5,750 pounds LVW;
(3)  light-duty trucks 6,001-8,500 pounds
				  GVWR and medium-duty passenger vehicles; and
(4) medium-duty and heavy-duty vehicles. The
				  fleet-average hydrocarbon emission value for each emission standard category
				  shall be calculated as follows:
Click
					 here to view image
where "n"=a manufacturer's total number of Option 2
					 certification evaporative families within an emission standard category for a
					 given model year;
"number of vehicles in the evaporative family"=the number
					 of vehicles produced and delivered for sale in California in the evaporative
					 family;
"family emission limit"=the numerical value selected by the
					 manufacturer for the evaporative family that serves as the emission standard
					 for the evaporative family with respect to all testing, instead of the emission
					 standard specified in this section
					 1976
					 (b)(1)(G)1.b. The family emission limit shall
					 not exceed 0.500 grams per test for passenger cars; 0.650 grams per test for
					 light duty trucks 6,000 pounds GVWR and under; 0.900 grams per test for
					 light-duty trucks 6,001-8,500 pounds GVWR; and 1.000 grams for medium-duty
					 passenger vehicles, medium-duty vehicles, and heavy-duty vehicles. In addition,
					 the family emission limit shall be set in increments of 0.025 grams per
					 test.
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 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, 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), or
				  the optional zero-fuel evaporative emission standards for 2001 through 2014
				  model motor vehicles, as described in section
				  1976(b)(1)(E).

								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 vehicles produced and
								delivered for sale by the manufacturer in California) 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.
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
								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, 2013, and 2014 model years. 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 2019 model year and be considered compliant with the requirements
				  of section
				  1976(b)(1)(G)1.
				  For all motor vehicles that are certified via this carry-over provision, the
				  emission standards set forth in section
				  1976(b)(1)(E)
				  shall apply when determining in-use compliance throughout the vehicle's useful
				  life. 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.

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 Pooling 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.
6.
Effective leak diameter standard
				  and procedure.
Manufacturers shall demonstrate that for 2018 and
				  subsequent model vehicles [LESS THAN EQUAL TO] 14,000 lbs. GVWR certifying to
				  the evaporative emission standards set forth in 1976(b)(1)(G), fuel systems do
				  not exceed an effective leak diameter of 0.02 inches when tested in accordance
				  with the test procedure sequence described in the "California Evaporative
				  Emission Standards and Test Procedures for 2001 and Subsequent Model Motor
				  Vehicles," incorporated by reference in section
				  1976(c). This
				  requirement does not apply to 2021 and previous model vehicles certified by a
				  small volume manufacturer. For vehicles with fuel tanks exceeding 25 gallons
				  nominal fuel tank capacity, manufacturers may request approval from the
				  Executive Officer for a leak standard greater than 0.020 inches, up to a
				  maximum value of 0.040 inches.
7.
Auxiliary engines and fuel systems.
For 2017 and subsequent
				  model vehicles [LESS THAN EQUAL TO]6,000 lbs. GVWR equipped with an auxiliary
				  engine and 2018 and subsequent model vehicles >6,000 lbs. GVWR equipped with
				  an auxiliary engine, manufacturers shall demonstrate compliance in accordance
				  with the provisions set forth in the "California Evaporative Emission Standards
				  and Test Procedures for 2001 through 2025 Model Year Passenger Cars, Light-Duty
				  Trucks, Medium-Duty Vehicles, and Heavy-Duty Vehicles and 2001 and Subsequent
				  Model Year Motorcycles" or the "California Evaporative Emission Standards and
				  Test Procedures for 2026 and Subsequent Model Year Passenger Cars, Light-Duty
				  Trucks, Medium-Duty Vehicles, and Heavy-Duty Vehicles," as applicable,
				  incorporated by reference in section
				  1976(c). These
				  requirements do not apply to 2021 and previous model vehicles certified by a
				  small volume manufacturer. For 2026 and subsequent model year motor vehicles,
				  these requirements apply to any auxiliary fuel system, including a fuel fired
				  heater. These requirements also apply to motor vehicles that are exempt from
				  exhaust emission certification, dedicated petroleum-fueled diesel vehicles, and
				  dedicated compressed natural gas-fueled vehicles.
(b)(2) Evaporative emissions for gasoline-fueled
					 motorcycles subject to exhaust emission standards under this article shall not
					 exceed:

				  standard
. Running loss emissions shall not exceed 0.01 grams per mile
				  for all vehicle types.
Phase-in schedule for running loss:
For each model year, a manufacturer shall certify, at a
					 minimum, the specified percentage of its vehicle fleet to these standards
					 according to the implementation schedule set forth below. For this calculation,
					 the manufacturer's vehicle fleet is defined as the total vehicles produced and
					 delivered for sale by the manufacturer in California that are subject to this
					 standard.

(1) Small volume manufacturers
					 are not required to comply with the phase-in schedule set forth in this table.
					 Instead, they must certify 100 percent of their 2028 and subsequent model year
					 vehicle fleet to the standards.
2. 2028 and subsequent model year vehicles
				  must meet the minimum canister size requirement for vehicles that have a tank
				  pressure exceeding 10 inches of water during the running loss test.
a Compliance with minimum canister size requirement is
					 demonstrated using the equation in the "California Evaporative Emission
					 Standards and Test Procedures for 2026 and Subsequent Model Year Passenger
					 Cars, Light-Duty Trucks, Medium-Duty Vehicles, and Heavy-Duty Vehicles,"
					 incorporated by reference in section
					 1976(c).
