(d) Requirements for Large Volume Manufacturers in Model Years 2012 

through 2017. 

(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 may 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 NEVs, other than limits described in 

subdivision C.7.6. The entire obligation may be met solely with credits generated from 

ZEVs.

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 zero-emission vehicle miles traveled (“VMT”) 

capability will generate an additional zero-emission VMT PZEV allowance, calculated as 

follows: 

 

Range Zero-emission VMT Allowance 

EAERu < 10 miles 0.0 

EAERu ≥10 to 40 miles EAERu x (1 – UFRcda)/11.028 

EAERu > 40 miles 

 (EAERu40) x [1 – 

(UF40*Rcda/EAERu)]/ 

11.028 

3.627 x (1 – UFn) 

Where, 

UF40= utility factor at 40 miles 

EAERu40= 40 miles 

n = 40 x (Rcda/EAERu) 

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

allowance. 

The urban equivalent all-electric range (EAERu) and urban charge depletion range 

actual (Rcda) 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), incorporated 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) (Rcda) shall be determined according to Section 

4.5.2 Equation 6 and the “Fleet UF” Utility Factor Equation Coefficients in Section 4.5.2, 

Table 3 of SAE J2841 March 2009.

8.2.6.2 Amend subparagraph (f)(2)(ix): At the conclusion of the 

US06 emission test, one of the following conditions shall apply: 

(i) For hybrid electric vehicles that do not allow manual 

activation of the auxiliary power unit and are charge-sustaining over the 

US06, record the battery state-of-charge to determine if the SOC criterion 

in section FG.10 is satisfied. If the SOC criterion is not satisfied, then 

repeat dynamometer test run from subparagraph (f)(2)(i) without the 

preconditioning cycle. A total of three US06 emission tests shall be 

allowed to satisfy the SOC criterion.
