On behalf of 104 organizations, the Center for Biological Diversity submits the attached comments regarding the proposed rule for aircraft engine particulate matter.
This rulemaking follows on 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 anticipates adopting PM standards that would be at least as stringent as ICAO's standards. The rulemaking would include retiring the existing smoke number standard for certain classes of aircraft engines and updating the measurement procedures for PM emissions. In addition, we are proposing to migrate 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 would be specified in this new part 1031.
