(1) 2012 through 2014 Requirements. On an annual basis, a manufacturer must meet the total ZEV obligation with ZEVs or ZEV credits generated by such vehicles, excluding credits generated by NEVs and Type 0 ZEVs, equal to at least 0.79% of its annual sales, using either production volume determination method described in subdivision C.2.1(b) No more than 50% of the total obligation may be met with credits generated from PZEVs,. No more than 75% of the total obligation may be met with credits generated from AT PZEVs. No more than 93.4% may be met with Enhanced AT PZEVs, Type 0 ZEVs, and NEVs, other than limits described in subdivision C.7.6. The entire obligation ma y be met solely with credits generated from

ZEVs.

(2) 2015 through 2017 Requirements. On an annual basis, a manufacturer must meet its ZEV obligation with ZEVs or ZEV credits generated by such vehicles, excluding credits generated by NEVs and Type 0 ZEVs, equal to at least 3% of its annual sales, using either production volume determination method described in subdivision C.2.1(b). No more than 42.8% of the total obligation may be met with credits generated from PZEVs. No more than 57.1% of the total obligation may be met with credits generated from AT PZEVs. No more than 78.5% may be met with credits generated from TZEVs, Type 0 ZEVs, and N EVs, other than limits described in subdivision C.7.6. The entire obligation ma y be met solely with credits generated from

3.3 Zero-Emission VMT PZEV Allowance

.

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

follows:

Range Zero-emission VMT Allowance

EAER
u < 10 miles 0.0

EAER
u ≥ 10 to 40 miles EAER
u x (1 – UF Rcda )/11.028

EAER
u > 40 miles (EAER u40 ) x [1 – (UF 40 *R cda /EAER
u )]/

11.028
3.627 x (1 – UF
n )

Where,

UF 40 = utility factor at 40 miles

EAER u40 = 40 miles
n = 40 x (R cda /EAER
u )

A vehicle cannot generate more than 1.39 zero-emission VMT PZEV

allowance.

The urban equivalent all-electric range (EAER
u ) and urban charge depletion range actual (R cda ) shall be determined in accordance with section G.5.411.4 and G.11.9, respectively, of these test procedures. The utility Factor (UF) shall be determined according to SAE International’s Surface Vehicle Information Report J2841 SEP2010 (Revised September 2010), incor porated by reference herein, from the Fleet Utility Factors (FUF) Table in Appendix B or using a polynomial curve fit with “FUF Fit” coefficients from Table 2 Utility Factor Equation Coefficients based on the charge depleting actual range (urban cycle) (R cda ) shall be determined according to Section 4.5.2 Equation 6 and the “Fleet UF” Utility Factor Equation Coe fficients in Section 4.5.2,

Table 3 of SAE J2841 March 2009.

(i) For hybrid electric vehicles that do not allow manual activation of the auxiliary power uni t and are charge-sustaining over the US06, record the battery state-of-char ge to determine if the SOC criterion

in section FG.10 is satisfied. If the SOC criterion is not satisfied, then repeat dynamometer test run fr om subparagraph (f)(2)(i) without the preconditioning cycle. A total of three US06 emission tests shall be allowed to satisfy the SOC criterion.
