Greenhouse Gas Emissions Standards for Heavy-Duty Engines and Vehicles Phase 3 (Proposed Rule)

This ICR covers the information collection activities associated with EPAs final rule promulgating new greenhouse gas (GHG) emissions standards for model year (MY) 2032 and later heavy-duty highway vehicles (the Phase 3 standards). These new standards phase in beginning as early MY 2027 for certain vehicle categories. This final rule also includes updates to the averaging, banking, and trading (ABT) program to restrict use of the multiplier portion of credits earned from advanced technologies, and provides other transitional flexibilities to assist manufacturers in the implementation of the Phase 3 program. The Agency is also finalizing additional revisions and clarifying editorial amendments to certain nonroad vehicle provisions in 40 CFR parts 1039 and 1054, certain highway heavy-duty vehicle provisions in 40 CFR part 1037, and certain test procedures for heavy-duty engines in 40 CFR part 1065. The new standards will apply to manufacturers beginning with MY 2027. Data would be submitted annually, consistent with EPAs existing certification program requirements. Information activities associated with the final rule are largely covered by existing emission certification and reporting requirements for EPAs heavy-duty engine (HDE) and heavy-duty vehicle (HDV) emission control program. This information collection statement covers only the additional burden associated with the final rule: reviewing the regulations, for all manufacturers; and complying with new customer-facing battery state-of-health monitor and warranty provisions, for plug-in hybrid and battery electric vehicle manufacturers, and making associated changes to vehicle owners manuals. Concerning other aspects of the rule, manufacturers already submit the data that would be required for certification to the standards to EPAs certification system (under programmatic ICRs); there would be a change only to the specific data, not to its reporting. The existing programmatic information collection request is: EPA ICR Number 0783.65, OMB Control Number 2060-0104, Motor Vehicle Emission Certification and Fuel Economy Compliance, 40 CFR Parts 86 and 600. To avoid duplication, this collection request covers only the incremental burden associated with the heavy-duty GHG Phase 3 final rule.
