Department of Transportation Federal Aviation Administration • 14 CFR Part 34 • [Docket No.: FAA-2023-2434; Amdt. No. 34-7] • RIN 2120-AL83 ( printed page 92787) AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; confirmation of effective date and response to public comments. SUMMARY: 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. DATES: The effective date of the final rule published on April 24, 2024 (89 FR 31078), is confirmed as May 24, 2024. Compliance was required by August 22, 2024.

SUPPLEMENTARY INFORMATION: Background Non-volatile Particulate Matter (nvPM) is a standard for measuring the amount of solid particles ( e.g. soot, etc. ) emitted by an aircraft. The Environmental Protection Agency (EPA) has adopted nvPM-based standards for aircraft engine emissions and certification test procedures to replace the old “Smoke Number” (SN) standard.[1] On May 24, 2024, the Federal Aviation Administration (FAA) implemented EPA's nvPM standard in Control of Non-Volatile Particulate Matter From Aircraft Engines: Emission Standards and Test Procedures (89 FR 31078). The FAA was statutorily required ( see42 U.S.C. 7572; Clean Air Act sec. 232) to incorporate the EPA's nvPM emissions standards into its own regulations and apply the regulatory requirements that will allow applicants to demonstrate compliance with the emissions standards at the time of engine airworthiness certification. Because the FAA does not have authority to make changes to the standards or procedures adopted by the EPA, and because the EPA issued its proposed rule for notice and sought public comment …
