7 CA Fleet Average NMOG Standards (50K mi.) PC & LDT ( lb. LVW) The California corporate average fleet requirements on NMOG are detailed in this chart. The manufacturer may distribute his vehicles between the TLEV, LEV, ULEV, and SULEV classifications provided that his California fleet average NMOG is less than or equal to the values specified in the chart for each model year. Through the 2003 model year these fleet averages are specified as part of the current California LEV I program and include all light - duty vehicles with loaded vehicle weights (LVW) up to 3750 lb. Values shown for the 2004 model year and beyond are part of the California LEV II program. The corporate fleet averages for 2005 model year and beyond also reflect the 10% ZEV sales mandate currently specified by California. The LEV II program includes provisions for partial ZEV credits (PZEV) for the introduction of certain high technology vehicles such as SULEV-class vehicles meeting a 150K mile SULEV emission requirement, certain hybrid electric vehicles, and fuel cell powered vehicles. 7

9 CA ZEV Program Requirements BEV Compliance Option In early 2001 CARB enacted several new features to their ZEV program. Included in these changes were establishing minimum ZEV sales percentages for model years beyond These percentages are shown in this chart. By the 2018 model year the minimum sales percentage covered by the ZEV program increases to 16% from the 10% levels required in CARB also has provided manufacturers with additional flexibilities in meeting these sales percentages. This chart breaks down the types of vehicles that a large volume manufacturer may use to fulfill these sales percentages. Options include BEVs (battery electric vehicles; also extended range hybrid electrics), advanced technology PZEVs (CNG-fueled vehicles, hybrid electrics, some fuel cell vehicles), and conventional gasoline PZEVs (150K mile SULEV emissions and OBD, meets CA zero evaporative emissions requirements). Intermediate volume manufacturers (max. of 60,000 units of CA production) may use conventional PZEVs for their entire ZEV requirement. In 2003 the ZEV program was modified again and a second, hydrogen fuel cell compliance option was added to provide manufacturers to focus on hydrogen fuel cells rather than battery electric vehicles if they so choose (see hydrogen fuel cell compliance option charts that follow). CARB also provided manufacturers with a phased-in PZEV introduction multiplier in the MY timeframe that reduces actual PZEV vehicles needed to fulfill the ZEV program requirements. More lenient intermediate compliance standards are also used for PZEVs introduced in the MY timeframe. 9

11 CA ZEV Program Requirements: Hydrogen FC Compliance Option In 2003 CARB modified their ZEV program again due to legal challenges regarding the use of fuel economy based credits and recognition that battery electric vehicles (BEVs) still lacked commercial viability. These 2003 modifications provide auto manufacturers with a second ZEV compliance option in addition to the BEV compliance option shown in the previous chart. This second compliance option allows manufacturers to produce increasing numbers of hydrogen fuel cell ZEVs in exchange for using advanced technology PZEVs (AT PZEVs, e.g., hybrids, CNG-fueled, hydrogen ICE vehicles) to meet their ZEV requirements. PZEV substitution for ZEVs remains fixed at the same 6% level associated with the 2001 BEV compliance option. The hydrogen fuel cell vehicle production requirements shown in this chart represent the total auto industry commitment for these vehicles over the time span shown (e.g., 250 total hydrogen fuel cell vehicles in the timeframe). These numbers would be reduced if some manufacturers decide to use the BEV compliance option. The 2003 program modifications also delete all fuel economy based credits for ZEVs or AT PZEVs and replace them with flat credits based on electric range or electric component capabilities. These credits start out with high values that eventually asymptote to their final levels. AT PZEV production during each model year period shown on the chart is also adjusted by fuel cell vehicle production during these same years. An independent review panel has also been established to monitor ZEV technologies and recommend additional changes to the program as needed going forward. 11

13 CA SFTP 4K Mile Standards (PC, LDT1, LDT2) Phase-in beginning 2001 MY California requirements for the supplemental FTP (SFTP) are summarized in this chart for passenger cars (PC), LDT1, and LDT2 light-duty truck weight classes (loaded vehicle weights [LVW] given in the chart). The SFTP requirements are applicable after 4K miles and are measured using two new test cycles (see charts under U.S. (Federal) for test cycle details). The US06 cycle covers high speed/high acceleration driving modes not covered during the normal FTP cycle. Air conditioner operation (A/C) is covered by the SC03 test cycle. Phase-in of the SFTP California requirements began with the 2001 model year. 13

15 CA LEV II 50K Mile Standards lb. GVW In the California LEV II program, a key component is a single set of tailpipe standards for all passenger cars and light-duty trucks with GVW (gross vehicle weight) of 8500 lb. or less (up to 10,000 lb GVW for passenger carrying vehicles). This chart summarizes 50K mile standards for LEV, ULEV, and SULEV vehicle categories in this broad weight classification. Fleet average NMOG values are also included in the LEV II program and these fleet averages are summarized in a chart in this application section for LDTs with LVWs greater than 3751 lb. but with a GVW of 8500 lb. or less. Vehicles with LVW less than 3751 lb. follow their own fleet average NMOG curve (see chart under passenger car applications). In the LEV II program, significantly lower NOx standards are required for LEV and ULEV categories compared to today's LEV and ULEV requirements. The LEV II program also introduces a SULEV category for this range of vehicles. Manufacturers may also certify up to 4% of their LDT2 trucks to a slightly higher NOx standard. This higher NOx emission standard is denoted as LEV/LDT2 in this chart. The LEV II requirements began with the 2004 model year. 15

17 CA LEV II 120K Mile Standards lb. GVW In the California LEV II program, a key component is a single set of tailpipe standards for all passenger cars and light-duty trucks with GVW (gross vehicle weight) of 8500 lb. or less (up to 10,00 lb GVW for passenger carrying vehicles). This chart summarizes 120K mile standards for LEV, ULEV, and SULEV vehicle categories in this broad weight classification. Fleet average NMOG values are also included in the LEV II program and these fleet averages are summarized in a chart in this application section for LDTs with LVWs greater than 3751 lb. but with a GVW of 8500 lb. or less. Vehicles with LVW less than 3751 lb. follow their own fleet average NMOG curve (see chart under passenger car applications). In the LEV II program, significantly lower NOx standards are required for LEV and ULEV categories compared to today's LEV and ULEV requirements. The LEV II program also introduces a SULEV category for this range of vehicles. Manufacturers may also certify up to 4% of their LDT2 trucks to a slightly higher NOx standard. This higher NOx emission standard is denoted as LEV/LDT2 in this chart. The LEV II requirements began with the 2004 model year. 17

57 CA Motorcycle Emission Standards California's motorcycle emission standards are shown in this chart. Emissions are measured using the FTP drive cycle but standards are given in g/km rather than g/mi. California provides standards for three different engine classes based on engine displacement: cc, cc, and engines greater than 699 cc. There are no standards for motorcycles with engines less than 50 cc displacement. For the larger two classes of engines (280 cc and larger) the HC standard is a corporate fleet average. No durability requirement is associated with these California standards. 57

63 CA Tier 2 Nonroad Gasoline Engine Emission Standards: Engines < 19 kw (< 25 hp)/0-65 cc (handheld devices) California's Tier 2 standards for small nonroad gasoline engines (< 25 hp) with engine displacements no larger than 65 cc are shown in this chart. These small displacement engines are typically used in handheld lawn & garden equipment or other small utility engine applications. The standards began with the 2000 model year and continued through the 2004 model year. Particulate matter (PM) standards apply only to 2-stroke engines. Durability requirements of either 50, 125, or 300 h are associated with these standards depending on the nature of the application. 63

These small displacement engines are typically used in handheld lawn & garden equipment or other small utility engine applications. The Tier 3 standards harmonize with federal standards on engines < 50 cc displacement and extend the Tier 2 emission standards up through 80 cc engines. These Tier 3 standards began with the 2005 model year. Particulate matter (PM) standards apply only to 2- stroke engines. Durability requirements of either 50, 125, or 300 h are associated with these standards depending on the nature of the application. 65

81 Federal & CA Cold CO Emission Standards 20 o F Requirement at 50K mi. U.S. federal and California standards for cold CO emission performance are summarized in this chart. For these cold CO standards, CO emissions are measured using the FTP driving cycle with a test temperature of 20 F. Details on the FTP driving cycle can be found under "test cycles" in this database. Cold CO standards are provided for different vehicle weight classes in both the U.S. and California. For the federal program higher cold CO standards are allowed for heavier light-duty trucks (LDT2, LDT3, LDT4, and Tier 2 MDPV federal weight classes). In California, higher cold CO emissions are allowed for LDT2, MDV2, and MDV3 weight classes (note that the CA LDT2 class includes the federal LDT3 and LDT4 weight classes). 81

83 CA Evaporative Emission Standards: LEV I vs. LEV II LEV I and LEV II California evaporative emission limits for light-duty and medium-duty vehicles are summarized in this chart. Evaporative emissions are measured using 2 day and 3 day diurnal tests conducted in sealed sheds. Standards are given in grams of hydrocarbons allowed in each of these diurnal test protocols. Evaporative emissions include contributions from a vehicle s fuel system, air intake system, engine gaskets, and non-fuel related components such as tires, fabric, and paint. LEV II evaporative standards began their phase-in with the 2004 model year and reduce evaporative emissions by more than 50% compared to California LEV I evaporative limits. LEV II evaporative compliance includes a 15 year/150,000 mile durability requirement. 83

87 Evaporative Emission Standards Phase-in: CA LEV II vs. EPA Tier 2 Phase-in requirements for California s LEV II and U.S. federal Tier 2 evaporative emission regulations are summarized in this chart. Evaporative emissions are measured using 2 day and 3 day diurnal tests conducted in sealed sheds. Evaporative emissions include contributions from a vehicle s fuel system, air intake system, engine gaskets, and non-fuel related components such as tires, fabric, and paint. Both evaporative emission regulations began their phase-in with the 2004 model year with the California program requiring complete compliance by the 2006 model year and the Tier 2 program requiring complete compliance one model year later. Manufacturers are expected to only produce vehicles that meet the tougher California LEV II evaporative requirements rather than develop and certify different systems for California and federal compliance. LEV II and Tier 2 evaporative compliance includes a 15 year/150,000 mile durability requirement. 87

89 Federal & CA Tier 1, Tier 2 Nonroad Diesel Engine Emission Standards: Engines < 37 kw (<50 hp) Federal and California Tier 1 and Tier 2 standards for non-road diesel engines are shown in this chart. Standards shown here cover engine sizes up to 37 kw (50 hp). These non-road engines are used in agricultural, construction, and industrial applications. Tier 1 standards were effective with the 2000 model year. Tier 2 standards were effective with the 2005 model year for engines up to 19 kw and effective with the 2004 model year for engines with power ratings from 19 to 37 kw. For these non-road diesel engines a version of the ISO steady-state engine test cycle is used to certify emission performance (e.g., ISO 8178 C1, 8 mode steady-state test cycle). Tier 1 and Tier 2 emission standards for these non-road diesel engines must be maintained over the engine's entire useful life. For engines up to 19 kw (25 hp), the useful life requirement is 5 years or 3000 hours of operation. For engines with power ratings from 19 to 37 kw, the useful life is 5 years or 3000 hours for constant speed engines > 3000 rpm, and 7 years or 5000 hours for all other engines in this class. 89
