Paperwork Redcution Act Burden Statement
This collection of information is approved by OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. (OMB Control No. 2060-0104). Responses to this collection of information is voluntary. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The public reporting and recordkeeping burden for this collection of information is estimated to be 5 minutes to 30 minutes per response. Send comments on the Agency’s need for this information, the accuracy of the provided burden estimates and any suggested methods for minimizing respondent burden to the Information Engagement Division Director, U.S. Environmental Protection Agency (2821T), 1200 Pennsylvania Ave., NW, Washington, D.C. 20460. Include the OMB control number in any correspondence. Do not send the completed form to this address.
The purpose of this form is to assist manufacturers in calculating fuel economy (FE) label values for the electric vehicles (EVs) they produce. The form may also be used to share information with the U.S. Environmental Protection Agency (EPA) to assist in review of fuel economy data under 40 CFR 600.312-08(a). The completed form should be emailed to the staff responsible for fuel economy label data, currently Hannah Frame ([email protected]) and Joshua Kimball ([email protected]).
Instructions for Completing This Form
For a simple EV label, please use the second tab, "EV Calculations (Calcs)." If voluntary adjustment of label values under 40 CFR 600.210-12(a) is intended, please use the third tab, "EV Calcs - Voluntarily Adjusted." Please note neither tab of this form is intended to calculate label fuel economy values for vehicles with multiple base levels. Please see 40 CFR 600.209-12 for more information on calculating the FE label values for a model type. Further instructions for completing the form may be found on the next two tabs.
