Summary

Manufacturers must tell the Secretary of Transportation whether they will meet the fuel‑economy standard for a model year, what steps they have taken or plan to take, and any other information the Secretary asks for. They must send that report during the 30 days before the model year starts and again in the 30‑day period that begins on the 180th day of the model year. If earlier steps are not enough, manufacturers must report extra steps and say whether those will ensure compliance. The reporting rule does not apply to a manufacturer covered by the alternative standard in section 32902(d). Under rules from the Secretary or the EPA Administrator, manufacturers must keep records, run tests, make reports, and provide requested items or information. A designated official may inspect vehicles and records if they show ID, and inspections must be at a reasonable time. U.S. district courts can order compliance and punish failure to obey as contempt.
