SUPPLEMENTARY INFORMATION:

This is a proposed extension of the ICR, which is currently approved through January 31, 2026. 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.

Public comments were previously requested via the Federal Register on July 22, 2025, during a 60-day comment period. This notice allows for an additional 30 days for public comments. Supporting documents, which explain in detail the information that the EPA will be collecting, are available in the public docket for this ICR. The docket can be viewed online at www.regulations.gov or in person at the EPA Docket Center, WJC West, Room 3334, 1301 Constitution Ave. NW, Washington, DC. The telephone number for the Docket Center is 202-566-1744. For additional information about EPA's public docket, visit http://www.epa.gov/​dockets.

Abstract: Under Sections 202(a) and 202(k) of the Clean Air Act (42 U.S.C. 7521), EPA finalized regulations to set more stringent vehicle emission standards beginning in model year 2017, as part of a systems approach to addressing the impacts of motor vehicles and fuels on air quality and public health. The Tier 3 vehicle emission standards, which are the subject of this ICR, reduce both tailpipe and evaporative emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. The Tier 3 vehicle standards are harmonized with California's Low Emission Vehicle Program—LEVIII standards, creating a federal vehicle emissions program allowing automakers to sell the same vehicles in all 50 states. This ICR covers the information that affected respondents must provide to the Agency. Any information submitted to the Agency for which a claim of confidentiality is made is safeguarded according to policies set forth in CFR title 40, chapter 1, part 2, subpart B— Confidentiality of Business Information (see 40 CFR part 2).

Form Numbers: Light-duty Cover of Outside Useful Life System (5800-257); Light-duty Conversion of Intermediate Age System (5800-258); Tier 3 Light-duty FTP and SFTP AB&T Reporting (5900-471); Tier 3 Heavy-duty NMOG+NO_X, Evaporative and Cold NMHC AB&T Reporting (5900-470); EPA Generic Electric Vehicle FE Label Calculator (PFN-3420-3); EPA Plug-In Hybrid Electric Vehicle Calculator (PFN-3420-4).

Respondents/affected entities: Light-duty vehicle and light-duty truck manufacturers, Independent commercial importers, On-highway heavy-duty engine & vehicle (>8,500 lbs GVWR) manufacturers Alternative fuel converters.

Respondent's obligation to respond: The respondent's obligation to respond is voluntary, but respondents who choose not to respond cannot obtain a Certificate of Conformity, and therefore cannot introduce their products into commerce in the U.S.

Estimated number of respondents: 49 (total).

Frequency of response: As needed.

Total estimated burden: 509,869 hours (per respondent, per year). Burden is defined at 5 CFR 1320.3(b).

Total estimated cost: $80,440,103 (per year), includes $43,090,093 annualized capital and operation & maintenance costs.

Changes in Estimates: There is a decrease of 14,475 hours in the total estimated respondent burden compared with the ICR currently approved by OMB. This decrease is primarily due to the reduction in the burden estimated for the fuel economy information collection. The reduction in this information collection was offset by increases in the burden for the Tier 3 emissions, in-use verification, and defect reporting information collections.
