Agency Information Collection Activities; Submission to the Office of Management and Budget for Review and Approval; Comment Request; Control of Air Pollution From Motor Vehicles: Tier 3 Motor Vehicle Emission Standards (Renewal)
Published Date: 1/29/2026
Notice
Summary
The EPA is asking to keep collecting info about car pollution rules called Tier 3 standards, which help keep our air clean. This affects car makers and anyone involved in vehicle emissions testing. They’re giving the public until March 2, 2026, to share thoughts, and this process won’t cost anyone extra right now.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Must Provide Data to Sell Vehicles
If you make or import vehicles, you must provide information to EPA to get a Certificate of Conformity. The notice says responding is voluntary, but firms that do not respond cannot obtain a Certificate of Conformity and therefore cannot introduce their products into U.S. commerce.
Large Estimated Compliance Burden
EPA estimates the ICR will require 509,869 hours and will cost $80,440,103 per year, including $43,090,093 in annualized capital and operation & maintenance costs. EPA estimates 49 respondents total will provide the information.
Net Burden Slightly Decreased
EPA reports a decrease of 14,475 hours in total estimated respondent burden compared with the currently approved ICR. The agency says the decrease is primarily from reduced fuel-economy information collection but was offset by increases in Tier 3 emissions, in-use verification, and defect reporting collections.
Which Firms Are Affected
EPA identifies affected entities as light-duty vehicle and light-duty truck manufacturers, independent commercial importers, on-highway heavy-duty engine and vehicle manufacturers (over 8,500 lbs GVWR), and alternative fuel converters. Those types of firms are the respondents to this information collection.

This means public water systems won’t have to monitor or treat these chemicals for now. People and water providers should weigh in by July 20, 2026, and a virtual hearing happens July 7.
2026-09895 — Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category-Unmanaged Combustion Residual Leachate
