Air Plan Approval; New York; New York Metropolitan Area Second Ten-Year Limited Maintenance Plan for the 2006 24-Hour PM2.5 Standard

摘要

The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), the limited maintenance plan (LMP) for the 2006 PM 2.5 national ambient air quality standard (NAAQS) for ten counties which comprise the New York portion of the New York-Northern New Jersey-Long Island (NY-NJ-CT) 2006 PM 2.5 NAAQS maintenance area. This LMP was submitted on October 15, 2024 by the New York State Department of Environmental Conservation (NYSDEC). The plan addresses the second ten-year maintenance period for particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers, known as PM 2.5 . The EPA is proposing approval of New York's LMP submission because it provides for the maintenance of the 2006 24-hour PM 2.5 NAAQS through the end of the second ten-year portion of the maintenance period. In addition, the EPA completed the adequacy review process of this New York PM 2.5 LMP for transportation conformity purposes on September 4, 2025.
