See section D.8 of th ese procedures for tolerance specifications.

“SOC Criterion” means the state-of-charge criterion that is applie d to chargesustaining hybrid electric vehicle to validate an e mission test. The SOC Criterion requires that no net change in battery energy occur s over a given test cycle, i.e. the final battery state-of-charge that is recorded at t he end of the emission test must be equivalent to the initial battery state-of-charge t hat is set at the beginning of the emission test. The SOC Net Change Tolerance shall be applied to the SOC Criterion.

“Section 177 State” means a state that is administering the Californi a ZEV requirements pursuant to section 177 of the federal Clean Air Act (42 U.S.C. § 7507). “Type 0, I, I.5, II, III, IV, and V ZEV” all have the meanings set forth in section C.4.4(a).

1. ZEV Emission Standard. The Executive Officer shall certify new 2009 and subsequent model passenger cars, light-duty tru cks and medium-duty vehicles as ZEVs if the vehicles produce zero exhaust emissions of any criteria pollutant (or precursor pollutant) under any and all possible ope rational modes and conditions.

2. Percentage ZEV Requirements

2.1 General Percentage ZEV Requirement.

(a) Basic Requirement. The minimum percentage ZEV requirement for each manufacturer is listed in the table below as the pe rcentage of the PCs and LDT1s, and LDT2s to the extent required by section C.2.2(c), p roduced by the manufacturer and delivered for sale in California that must be ZEVs, subject to the conditions in section

C.2.2.

Model Years Minimum ZEV Requirement

2009 through 2011 11 % 2012 through 2014 12 % 2015 through 2017 14 % 2018 and subsequent 16 %

(b) Calculating the Number of Vehicles to Which the Per centage ZEV Requirement is Applied. For the 2009 through 2011 model years, a manufact urer’s production volume of PCs and LDT1s, and LDT2s as ap plicable, produced and

delivered for sale in California will be based on t he three-year average of the manufacturer’s volume of PCs and LDT1s, and LDT2s a s applicable, produced and delivered for sale in California in the 2003 throug h 2005 model years. For 2012 and subsequent model years, a manufacturer’s production volume for the given model year will be based on the three-year average of the manu facturer’s volume of PCs and LDT1s, and LDT2s, as applicable, produced and deliv ered for sale in California in the prior fourth, fifth and sixth years [for example, 2 013 model-year ZEV requirements will be based on California production volumes of PCs an d LDT1s, and LDT2s as applicable, for the 2007 to 2009 model years]. Thi s production averaging is used to determine ZEV requirements only, and has no effect on a manufacturer’s size determination. As an alternative to the three year averaging of prior year production described above, a manufacturer may elect to base i ts ZEV obligation on the number of PCs and LDT1s, and LDT2s, as applicable, produced b y the manufacturer and delivered for sale in California that same model ye ar. For 2012 and subsequent model years, a manufacturer may, on an annual basis, sele ct either the three-year average or the same model-year calculation method. In applyin g the ZEV requirement, a PC, LDT1, or LDT2 as applicable, that is produced by on e manufacturer (e.g., Manufacturer A), but is marketed in California by another manufa cturer (e.g., Manufacturer B) under the other manufacturer’s (Manufacturer B) nameplate , shall be treated as having been produced by the marketing manufacturer (Manufacture r B).Final Regulation Order – Part 6

Hearing Date: 03/27/08
Adopted: 12/17/08 C-2 (c) Phase-in of ZEV Requirements for LDT2s. Beginning with the ZEV requirements for the 2009 model year, a manufacture r’s LDT2 production shall be included in determining the manufacturer’s overall ZEV requirement under section C.2.1(a) in the increasing percentages shown in the table below.

2009 2010 2011 2012+

51% 68% 85% 100%

(d) Exclusion of ZEVs in Determining a Manufacturer’s S ales Volume. In calculating, for purposes of sections C.2.1(b) and (c), the volume of PCs, LDT1s and LDT2s a manufacturer has produced and delivered for sale in California, the manufacturer shall exclude the number of ZEVs produ ced by the manufacturer, or by a subsidiary in which the manufacturer has a greater than 50 percent ownership interest,

and delivered for sale in California.

2.2 Requirements for Large Volume Manufacturers.

(a) Primary Requirements for Large Volume Manufacturers through Model

Year 2011 . In the 2009 through 2011 model years, a manufact urer must meet at least 22.5 percent of its ZEV requirement with ZEVs or ZE V credits generated by such vehicles, and at least another 22.5 percent with ZE Vs, AT PZEVs, or credits generated by such vehicles. The remainder of the manufacture r’s ZEV requirement may be met using PZEVs or credits generated by such vehicles.

(b) Alternative Requirements for Large Volume Manufactu rers.

(1) Minimum Floor for Production of Type III ZEVs.

(A) [ RESERVED]

(B) Requirement For the 2009-2011 Model Years. A manufacturer electing the alternative compliance requirements during mode l years 2009 through 2011 must produce ZEV credits equal to 0.82 percent of the ma nufacturer’s average annual California sales of PCs and LDT1s, and LDT2s, as ap plicable, over the three-year period from model years 2003 through 2005, though p roduction, delivery for sale, and placement in service of ZEVs, other than NEVs and T ype 0 ZEVs, using credit ratios for each ZEV Type compared to a Type III prescribed in the table below, or submit an equivalent number of credits generated by such vehi cles.

Hearing Date: 03/27/08
Adopted: 12/17/08 C-3 (i) Manufacturers may use credits generated by 199 7-2003 model-year ZEVs that qualify for an extended service multiplier und er section C.6 for a year primarily during calendar years 2009-2011, provided that 33 y ears of such a multiplier will equal

4 ZEV credits.

(C) [ RESERVED]

(D) [ RESERVED]

(E) [ RESERVED]

(F) Exclusion of Additional Credits for Transportation Systems. Any additional credits for transportation systems generated in acc ordance with section C.7.5 shall not be counted towards compliance with this section C.2 .2(b)(1)(B).

(G) Carry-over of Excess Credits. ZEV credits generated from excess production in model years 2005 through 2008 may be carried forward and applied to the 2009 through 2011 minimum floor requirement spe cified in section C.2.2(b)(1)(B) provided that the value of these carryover credits shall be based on the model year in

which the credits are used

. Beginning with the 2012 model year, these credits m ay no longer be used to meet the ZEV requirement; they ma y be used as Enhanced AT PZEV, AT PZEV, or PZEV credits. ZEV credits earned in model year 2009 and subsequent would be allowed to be carried forward f or two years for application to the ZEV requirement. For example, ZEV credit earned in the 2010 model year would retain full flexibility through the 2012 model year, at wh ich time that credit could only be used as Enhanced AT PZEV, AT PZEV, or PZEV credits, and could not be used to satisfy the ZEV credit obligation, which may only be satisf ied with credit generated from ZEVs.

(H) Failure to Meet Requirement for Production of ZEVs. A manufacturer that, after electing the alternative requirements i n section C.2.2(b) for any model year from 2009 through 2011, fails to meet the requireme nt in section C.2.2(b)(1)(B) by the end of the 2011 model year, shall be treated as sub ject to the primary requirements in section C.2.1(a) for the 2009 through 2011 model ye ars.

(I) Rounding Convention. The number of ZEVs needed for a manufacturer under section C.2.2(b)(1)(B) shall be rounded to th e nearest whole number.

(2) Compliance With Percentage ZEV Requirements. In the 2009 through 2011 model years, a manufacturer electing the alter native compliance requirements in a given model year must meet at least 45 percent of its ZEV requirement for that model year with ZEVs, AT PZEVs or Enhanced AT PZEVs, or c redits generated from such vehicles. ZEV credits generated for compliance wit h the alternative requirements during any given model year will be applied to the 45 percent which may be met with ZEVs, AT PZEVs, Enhanced AT PZEVs, or credits gener ated from such vehicles, butFinal Regulation Order – Part 6

Hearing Date: 03/27/08
Adopted: 12/17/08 C-4 not PZEVs. The remainder of the manufacturer’s ZEV requirement may be met using PZEVs or credits generated from such vehicles.

(3) Sunset of Alternative Requirements After the 2011 M odel Year. The alternative requirements in section C.2.2(b) are no t available after the 2011 model year.

(c) Election of the Primary or Alternative Requirements for Large Volume

Manufacturers. A manufacturer shall be subject to the primary ZE V requirements for the 2009 model year unless it notifies the Executiv e Officer in writing prior to the start of the 2009 model year that it is electing to be subje ct to the alternative compliance requirements for that model year. Thereafter, a ma nufacturer shall be subject to the same compliance option as applied in the previous m odel year unless it notifies the Executive Officer in writing prior to the start of a new model year that it is electing to switch to the other compliance option for that new model year. However, a manufacturer that has previously elected the primar y ZEV requirements for one or more of the 2009 through 2011 model years may prior to t he end of the 2011 model year elect the alternative compliance requirements for t he 2009 through 2011 model years upon a demonstration that it has complied with all of the applicable requirements for that period in section C.2.2(b)(1)(B).

(d) Requirements for Large Volume Manufacturers in Mode l Years 2012 through 2017.

(1) 2012 through 2014 Requirements. A manufacturer must meet the total ZEV obligation with ZEVs or ZEV credits generated b y such vehicles, excluding NEVs and Type 0 ZEVs, equal to at least 0.79% of its ann ual sales, using either production

volume determination method described in section C. 2.1(b) No more than 50% of the total obligation may be met with PZEVs, No more th an 75% of the total obligation may be met with AT PZEVs. No more than 93.4% may be me t with Enhanced AT PZEVs, Type 0 ZEVs, and NEVs, other than limits described in section C.7.6. The entire requirement may be met solely with ZEVs.

(2) 2015 through 2017 Requirements. A manufacturer must meet its ZEV obligation with ZEVs or ZEV credits generated by su ch vehicles, excluding NEVs and Type 0 ZEVs, equal to at least 3% of its annual sal es, using either production volume determination method described in section C.2.1(b). No more than 42.8% of the total obligation may be met with PZEVs, No more than 57. 1% of the total obligation may be met with AT PZEVs. No more than 78.5% may be met w ith Enhanced AT PZEVs, Type 0 ZEVs, and NEVs, other than limits described in se ction C.7.6. The entire requirement may be met solely with ZEVs.Final Regulation Order – Part 6

Hearing Date: 03/27/08
Adopted: 12/17/08 C-5 (3) The following table enumerates a manufacturer’s annual percentage obligation for the 2012 though 2017 model years if the manufacturer produces the minimum number of credits required to meet its ZEV obligation and the maximum percentage for the Enhanced AT PZEV, AT PZEV, and P ZEV categories.

(4) Use of Additional Credits for Transportation System s. Any additional credits for transportation systems generated in acc ordance with section C.7.5 may be used to meet up to one tenth of the portion of the ZEV obligation which must be met with ZEVs, specified in section C.2.2(d).

(e) Requirements for Large Volume Manufacturers in Mode l Year 2018 and Subsequent. In the 2018 and subsequent model years, a manufact urer must meet a ZEV total percent requirement of 16 percent. The m aximum portion of a manufacturer’s percentage ZEV requirement that may be satisfied by PZEVs that are not Enhanced AT PZEVs or AT PZEVs, or credits gener ated by such vehicles, is limited to 6 percent of the manufacturer’s applicable Calif ornia PC, LDT1, and LDT2 production volume; Enhanced AT PZEVs and AT PZEVs o r credits generated by such vehicles may be used either alone or in combination , to meet up to one-half of the manufacturer’s remaining ZEV requirement.

2.3 Requirements for Intermediate Volume Manufactur ers. In 2009 and subsequent model years, an intermediate volume manu facturer may meet its ZEV requirement with up to 100 percent PZEVs or credits generated by such vehicles.

2.4 Requirements for Small Volume Manufacturers and Independent Low

Volume Manufacturers. A small volume manufacturer or an independent lo w volume manufacturer is not required to meet the percentage ZEV requirements. However, a small volume manufacturer or an independent low vol ume manufacturer may earn and market credits for the ZEVs or PZEVs it produces an d delivers for sale in California.

2.5 Counting ZEVs and PZEVs in Fleet Average NMOG Calcu lations . For purposes of calculating a manufacturer’s fleet aver age NMOG value and NMOG credits under sections 1961(b) and (c), title 13, CCR, a ve hicle certified as a ZEV is counted as one ZEV, and a PZEV is counted as one SULEV certifi ed to the 150,000 mile standards, regardless of any ZEV or PZEV multiplier s.

.Final Regulation Order – Part 6

Hearing Date: 03/27/08
Adopted: 12/17/08 C-6 2.7 Changes in Small Volume, Independent Low Volume , and

Intermediate Volume Manufacturer Status.

(a) Increases in California Production Volume. In 2009 and subsequent model years, if a small volume manufacturer’s average Cal ifornia production volume exceeds 4,500 units of new PCs, LDTs, and MDVs based on the average number of vehicles produced and delivered for sale for the three previ ous consecutive model years, or if an independent low volume manufacturer’s average Calif ornia production volume exceeds 10,000 units of new PCs, LDTs, and MDVs based on th e average number of vehicles produced and delivered for sale for the three previ ous consecutive model years, the manufacturer shall no longer be treated as a small volume, or independent low volume manufacturer, as applicable, and shall comply with the ZEV requirements for intermediate volume manufacturers, as applicable, b eginning with the sixth model year after the last of the three consecutive model years

.

If an intermediate volume manufacturer’s average Ca lifornia production volume exceeds 60,000 units of new PCs, LDTs, and MDVs bas ed on the average number of vehicles produced and delivered for sale for the th ree previous consecutive model years (i.e., total production volume exceeds 180,00 0 vehicles in a three-year period), the manufacturer shall no longer be treated as an i ntermediate volume manufacturer and shall, beginning with the sixth model year afte r the last of the three consecutive model years, comply with all ZEV requirements for l arge volume manufacturers.

Requirements will begin in the fourth model year ra ther than the sixth model year

when a manufacturer ceases to be a small or interme diate volume manufacturer in 2003 or subsequent years due to the aggregation req uirements in majority ownership situations, except that if the majority ownership i n the manufacturer was acquired prior to the 2001 model year, the manufacturer must compl y with the stepped-up ZEV requirements starting in the 2010 model year.

(b) Decreases in California Production Volume. If a manufacturer’s average California production volume falls below 4,500, 10, 000 or 60,000 units of new PCs, LDTs, and MDVs, as applicable, based on the average number of vehicles produced and delivered for sale for the three previous conse cutive model years, the manufacturer shall be treated as a small volume, independent low volume, or intermediate volume manufacturer, as applicable, and shall be subject t o the requirements for a small volume, independent low volume, or intermediate vol ume manufacturer beginning with the next model year.

(c) Calculating California Production Volume in Change of Ownership Situations. Where a manufacturer experiences a change in owners hip in a particular model year, the change will affect application of the aggregati on requirements on the manufacturer starting with the next model year. The manufacture r’s small or intermediate volume manufacturer status for the next model year shall b e based on the average California production volume in the three previous consecutive model years of those manufacturers whose production volumes must be aggr egated for that next model year.Final Regulation Order – Part 6

Hearing Date: 03/27/08
Adopted: 12/17/08 C-7 For example, where a change of ownership during the 2010 model year results in a requirement that the production volume of Manufactu rer A be aggregated with the production volume of Manufacturer B, Manufacturer A ’s status for the 2011 model year will be based on the production volumes of Manufact urers A and B in the 2008-2010 model years. Where the production volume of Manufa cturer A must be aggregated with the production volumes of Manufacturers B and C for the 2010 model year, and during that model year a change in ownership eliminates th e requirement that Manufacturer B’s production volume be aggregated wi th Manufacturer A’s, Manufacturer A’s status for the 2011 model year wil l be based on the production

volumes of Manufacturers A and C in the 2008-2010 m odel years. In either case, the lead time provisions in sections C2.7(a) and (b) wi ll apply.

3. Partial ZEV Allowance Vehicles (PZEVs).

3.1 Introduction

. This section C.3 sets forth the criteria for iden tifying

vehicles delivered for sale in California as PZEVs. A PZEV is a vehicle that cannot be certified as a ZEV but qualifies for a PZEV allowan ce of at least 0.2.

3.2 Baseline PZEV Allowance

. In order for a vehicle to be eligible to receive a PZEV allowance, the manufacturer must demonstrate compliance with all of the following requirements. A qualifying vehicle will receive a baseline PZEV allowance of

0.2.

(a) SULEV Standards. Certify the vehicle to the 150,000-mile SULEV

exhaust emission standards for PCs and LDTs in sect ion 1961(a)(1), title 13, CCR. Bi-fuel, fuel-flexible and dual-fuel vehicles must certify to the applicable 150,000-mile SULEV exhaust emission standards when operating on both fuels;

(b) Evaporative Emissions. Certify the vehicle to the evaporative emission standards in section 1976(b)(1)(E), title 13, CCR z ero-fuel evaporative emissions standards);

(c) OBD. Certify that the vehicle will meet the applicable on-board diagnostic requirements in sections 1968.1 or 1968.2, title 13 , CCR, as applicable, for 150,000 miles; and

(d) Extended Warranty. Extend the performance and defects warranty perio d set forth in sections 2037(b)(2) and 2038(b)(2) to 15 years or 150,000 miles, whichever occurs first, except that the time period is to be 10 years for a zero emission energy storage device used for traction power (such as a b attery, ultracapacitor, or other electric storage device).Final Regulation Order – Part 6

Hearing Date: 03/27/08
Adopted: 12/17/08 C-8 3.3 Zero-Emission VMT PZEV Allowance

.

(a) Calculation of Zero Emission VMT Allowance. A vehicle that meets the requirements of section C.3.2 and has zero-emission vehicle miles traveled (“VMT”) capability will generate an additional zero emissio n VMT PZEV allowance, calculated as

follows:

Range Zero-emission VMT Allowance

EAER < 10 miles 0.0

EAER >=10 miles

and

R cda = 10 miles to 40 miles EAER x (1 – UF Rcda )/11.028

R cda >40 miles EAER 40 / 29.63

The urban equivalent all-electric range (EAER) and urban charge depletion range actual (R cda ) shall be determined in accordance with section E. 3.2.1 of these test procedures.

replacing 95 miles (UDDS ZEV range) in ≤ 10 minutes per section C.4.4(b) Type III

≥ 200 N/A

Type IV ≥ 200 Must be capable of replacing 190 miles (UDDS ZEV range) in ≤ 15 minutes per section C.4.4(b)

Type V ≥ 300 Must be capable of replacing 285 miles (UDDS ZEV range) in ≤ 15 minutes per section C.4.4(b)

(b) Fast Refueling . The “fast refueling capability” requirement for a 2009 and subsequent model-year Type III, IV, or V ZEV in sec tion C.4.4.(a) will be considered met if the Type III ZEV has the capability to accum ulate at least 95 miles of UDDS range in 10 minutes or less and the Type IV or V ZE V has the capability to accumulate at least 190 or 285 miles, respectively, in 15 minu tes or less. For ZEVs that utilize more than one ZEV fuel, such as plug-in fuel cell vehicl es, the Executive Officer may choose to waive these section C.4.4.(b) fast fueling requi rements and base the amount of credit earned on UDDS ZEV range, as specified in section C .4.4.(a).

(c) ZEV Credits for 2009 and Subsequent Model-Year ZEVs

. A 2009 and subsequent model-year ZEV, other than a NEV or Type 0, earns 1 ZEV credit when it is produced and delivered for sale in California. A 2 009 and subsequent model-year ZEV earns additional credits based on the earliest year in which the ZEV is placed in service (not earlier than the ZEV’s model year).

Hearing Date: 03/27/08
Adopted: 12/17/08 C-16 requirement set forth in section C.2 shall earn ZEV credits in accordance with this

section C.7.

7.2 ZEV Credit Calculations.

(a) Credits from ZEVs . The amount of g/mi ZEV credits earned by a manufacturer in a given model year from ZEVs shall be expressed in units of g/mi NMOG, and shall be equal to the number of credits f rom ZEVs produced and delivered for sale in California that the manufacturer applie s towards meeting the ZEV requirements for the model year subtracted from the number of ZEVs produced and delivered for sale in California by the manufacture r in the model year and then multiplied by the NMOG fleet average requirement fo r PCs and LDT1s, or LDT2s as applicable, for that model year.

(b) Credits from PZEVs. The amount of g/mi ZEV credits from PZEVs earned by a manufacturer in a given model year shall be ex pressed in units of g/mi NMOG, and shall be equal to the total number of PZEV allowanc es from PZEVs produced and

delivered for sale in California that the manufactu rer applies towards meeting its ZEV requirement for the model year subtracted from the total number of PZEV allowances from PZEVs produced and delivered for sale in Calif ornia by the manufacturer in the model year and then multiplied by the NMOG fleet av erage requirement for PCs and LDT1s, or LDT2s as applicable, for that model year.

(c) Separate Credit Accounts. The number of credits from a manufacturer’s [i] ZEVs, [ii] enhanced AT PZEVs, [iii] AT PZEVs, [ iv] all other PZEVs, and [v] NEVs shall each be maintained separately.

7.3 ZEV Credits for MDVs and LDTs Other Than LDT1s . ZEVs and PZEVs classified as MDVs or as LDTs other than LDT1s may be counted toward the ZEV requirement for PCs, LDT1s and LDT2s as applicable, and included in the calculation of ZEV credits as specified in this section C.7 if the manufacturer so designates.

7.4 ZEV Credits for Advanced Technology Demonstrati on Programs . In model years 2009 through 2014, ZEVs and Enhanced AT PZEVs, excluding NEVs, placed in a California advanced technology demonstr ation program for a period of two or more years, may earn ZEV credits even if it is n ot “delivered for sale” or registered with the California Department of Motor Vehicles (D MV). To earn such credits, the

manufacturer must demonstrate to the reasonable sat isfaction of the Executive Officer that the vehicles will be regularly used in applica tions appropriate to evaluate issues related to safety, infrastructure, fuel specificati ons or public education, and that for 50 percent or more of the first two years of placement the vehicle will be operated in California. Such a vehicle is eligible to receive the same allowances and credits that it would have earned if placed in service. To determi ne vehicle credit, the model-year designation for a demonstration vehicle shall be co nsistent with the model-year designation for conventional vehicles placed in the same timeframe. Manufacturers may earn credit for as many as 25 vehicles per model, per ZEV state, per year underFinal Regulation Order – Part 6

Hearing Date: 03/27/08
Adopted: 12/17/08 C-17 this section C.7.4. A manufacturer’s vehicles in e xcess of the 25-vehicle cap will not be eligible for advanced technology demonstration prog ram credits.

7.5 ZEV Credits for Transportation Systems

.

(a) General. In model years 2009 and subsequent, a ZEV placed, for two or more years, as part of a transportation system may earn additional ZEV credits, which may be used in the same manner as other credits ear ned by vehicles of that category, except as provided in section C.7.5(c) below. In m odel years 2009 through 2011, an Enhanced AT PZEV, AT PZEV or PZEV placed as part of a transportation system may earn additional ZEV credits, which may be used in t he same manner as other credits earned by vehicles of that category, except as prov ided in section C.7.5(c) below. A NEV is not eligible to earn credit for transportati on systems. To earn such credits, the

manufacturer must demonstrate to the reasonable sat isfaction of the Executive Officer that the vehicle will be used as a part of a projec t that uses an innovative transportation system as described in section C.7.5(b) below.

(b) Credits Earned. In order to earn additional credit under this sect ion C.7.5, a project must at a minimum demonstrate [i] shared use of ZEVs, Enhanced AT PZEVs, AT PZEVs or PZEVs, and [ii] the application of “intelligent” new technologies such as reservation management, card systems, depot management, location management, charge billing and real-time wireless i nformation systems. If, in addition to factors [i] and [ii] above, a project also featu res linkage to transit, the project may receive further additional credit. For ZEVs only, not including NEVs, a project that features linkage to transit, such as dedicated park ing and charging facilities at transit stations, but does not demonstrate shared use or th e application of intelligent new technologies, may also receive additional credit fo r linkage to transit. The maximum credit awarded per vehicle shall be determined by t he Executive Officer, based upon an application submitted by the manufacturer and, if a ppropriate, the project manager.

The maximum credit awarded shall not exceed the fol lowing:

(1) ZEVs. Credits earned or allocated by ZEVs pursuant to t his section C.7.5, not including all credits earned by the vehicle its elf, may be used to satisfy up to onetenth of a manufacturer’s ZEV obligation in any giv en model year, and may be used to satisfy up to one-tenth of a manufacturer’s ZEV obl igation which must be met with ZEVs, as specified in section C.2.2(d)(3).

(2) Enhanced AT PZEVs . Credits earned or allocated by Enhanced AT PZEVs pursuant to this section C.7.5, not including all credits earned by the vehicle itself, may be used to satisfy up to one-tenth of a manufacturer’s ZEV obligation in any given model year, but may only be used in the same manner as other credits earned by vehicles of that category.

(3) AT PZEVs. Credits earned or allocated by AT PZEVs pursuant to this section C.7.5, not including all credits earned by the vehicle itself, may be used to satisfy up to one-twentieth of a manufacturer’s ZEV obligation in any given model year, but may only be used in the same manner as other cr edits earned by vehicles of that category.

(4) PZEVs. Credits earned or allocated by PZEVs pursuant to this section C.7.5, not including all credits earned by the vehi cle itself, may be used to satisfy up to one-fiftieth of the manufacturer’s ZEV obligation i n any given model year, but may only

be used in the same manner as other credits earned by vehicles of that category.

(d) Allocation of Credits. Credits shall be assigned by the Executive Officer to the project manager or, in the absence of a separat e project manager, to the vehicle manufacturers upon demonstration that a vehicle has been placed in a project. Credits shall be allocated to vehicle manufacturers by the Executive Officer in accordance with a recommendation submitted in writing by the projec t manager and signed by all manufacturers participating in the project, and nee d not be allocated in direct proportion to the number of vehicles placed.

7.6 Use of ZEV Credits . A manufacturer may meet the ZEV requirements in any given model year by submitting to the Executive Officer a commensurate amount of g/mi ZEV credits, consistent with section C.2. Cre dits in each of the categories may be used to meet the requirement for that category as w ell as the requirements for lesser credit earning ZEV categories, but shall not be use d to meet the requirement for a greater credit earning ZEV category. For example, credits produced from Enhanced AT PZEVs may be used to comply with AT PZEV requiremen ts, but not with the portion that must be satisfied by ZEVs. These credits may be earned previously by the manufacturer or acquired from another party.Final Regulation Order – Part 6

Adopted: 12/17/08 C-20 (b) Carry forward provisions for Large Volume Manufactu rers. ZEV credits generated from excess production in model years 200 9 and subsequent, including those acquired from another party, may be carried f orward and applied to the ZEV minimum floor requirement specified in sections C.2 .2(b)(1)(B) and (d) for two subsequent model years. Beginning with the third s ubsequent model year, those earned ZEV credits may no longer be used to satisfy the manufacturer’s percentage ZEV obligation that may only be satisfied by credit s from ZEVs, but may be used to satisfy the manufacturer’s percentage ZEV obligatio n that may be satisfied by credits from Enhanced AT PZEVs, AT PZEVs, or PZEVs. For ex ample, ZEV credit earned in 2010 would retain full flexibility through 2012, af ter which time that credit could only be used as Enhanced AT PZEV, AT PZEV, or PZEV credits.

(c) Carry forward provisions for manufacturers other than Large Volume

Manufacturers. ZEV credits generated from 2009 and subsequent mo del year production by manufacturers that are not large volu me manufacturers may be carried forward by the manufacturer producing the ZEV credi t until the manufacturer becomes subject to the large volume manufacturer requiremen ts, after the transition period permitted in section C.2.7(a). When subject to the large volume manufacturer requirements, a manufacturer must comply with the p rovisions of section C.7.6(b).

ZEV credits traded by a manufacturer other than a l arge volume manufacturer to any other manufacturer, including a large volume manufa cturer, are subject to section C.7.6(b), beginning in the model year in which they were produced (e.g., a 2009 model year ZEV credit traded in calendar year 2010 can on ly be applied towards the portion of the manufacturer’s requirement that must be met wit h ZEVs through model year 2011; beginning in model year 2012, the credit can only b e applied to the portion of the manufacturer’s requirement that may be met with Enh anced AT PZEVs, AT PZEVs, or PZEVs).

7.7 Requirement to Make Up a ZEV Deficit
