## Abstract

This action confirms the effective date of the final rule published on April 24, 2024, and responds to the comments received on that final rule. The FAA published a correction on May 7, 2024, to the final rule that established a compliance date of 90 days after the effective date. The rule adopts standards for measuring non-volatile particulate matter (nvPM) exhaust emissions from aircraft engines. With this rulemaking, the FAA implemented the nvPM emissions standards adopted by the Environmental Protection Agency (EPA), allowing manufacturers to certificate engines to the new nvPM emissions standards in the United States, and fulfilling the statutory obligations of the FAA under the Clean Air Act.
