Section 1037.250 - Reporting and recordkeeping(a) By September 30 following the end of the model year, send the Designated Compliance Officer a report including the total U.S.-directed production volume of vehicles you produced in each vehicle family during the model year (based on information available at the time of the report). Report by vehicle identification number and vehicle configuration and identify the subfamily identifier. Report uncertified vehicles sold to secondary vehicle manufacturers. We may waive the reporting requirements of this paragraph (a) for small manufacturers.(b) Organize and maintain the following records: (1) A copy of all applications and any summary information you send us.(2) Any of the information we specify in § 1037.205 that you were not required to include in your application.(3) A detailed history of each emission-data vehicle (including emission-related components), if applicable.(4) Production figures for each vehicle family divided by assembly plant.(5) Keep a list of vehicle identification numbers for all the vehicles you produce under each certificate of conformity. Also identify the technologies that make up the certified configuration for each vehicle you produce.(c) Keep required data from emission tests and all other information specified in this section for eight years after we issue your certificate. If you use the same emission data or other information for a later model year, the eight-year period restarts with each year that you continue to rely on the information.(d) Store these records in any format and on any media, as long as you can promptly send us organized, written records in English if we ask for them. You must keep these records readily available. We may review them at any time.(e) If you fail to properly keep records or to promptly send us information as required under this part, we may require that you submit the information specified in this section after each calendar quarter, and we may require that you routinely send us information that the regulation requires you to submit only if we request it. If we find that you are fraudulent or grossly negligent or otherwise act in bad faith regarding information reporting and recordkeeping, we may require that you send us a detailed description of the certified configuration for each vehicle before you produce it. 81 FR 74048 , Oct. 25, 2016, as amended at 88 FR 4639 , Jan. 24, 2023 81 FR 74048 , 10/25/2016, as amended at 88 FR 4639 , 3/27/2023
