Revisions to the Air Emissions Reporting Requirements

This action proposes changes to the EPA's Air Emissions Reporting Requirements (AERR). The proposed amendments may require changes to current regulations of State, local, and certain tribal air agencies; would require these agencies to report emissions data to the EPA using different approaches from current requirements; and would require owners/operators of some facilities to report additional emissions data.

Control of Air Pollution From New Motor Vehicles: Heavy-Duty Engine and Vehicle Standards

The Environmental Protection Agency (EPA) is finalizing a program to further reduce air pollution, including ozone and particulate matter (PM), from heavy-duty engines and vehicles across the United States. The final program includes new emission standards that are significantly more stringent and that cover a wider range of heavy-duty engine operating conditions compared to today's standards; further, the final program requires these more stringent emissions standards to be met for a longer period of when these engines operate on the road.
