EPA/OAR RIN: 2060-AU69 Publication ID: Fall 2022 
Title: Control of Air Pollution From Aircraft Engines: Emission Standards and Test Procedures 

This rulemaking follows the International Civil Aviation Organization (ICAO) agreement on the international particulate matter (PM) emission standards for commercial aircraft engines in February 2019. Domestically the EPA adopted PM standards that match the ICAO standards, including replacing the existing smoke number visibility standard with a PM-based standard for certain classes of engines. The rulemaking also included new measurement procedures for PM emissions and visibility control that align with those of ICAO. In addition, we migrated the aircraft engine regulations from the existing 40 CFR part 87 to a new 40 CFR part 1031, and the new aircraft engine PM standards and requirements described earlier will be specified in this new part 1031.
