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

What it does

The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), the limited maintenance plan (LMP) for the 2006 PM<INF>2.5</INF> 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<INF>2.5</INF> 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<INF>2.5</INF>. The EPA is proposing approval of New York's LMP submission because it provides for the maintenance of the 2006 24-hour PM<INF>2.5</INF> 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<INF>2.5</INF> LMP for transportation conformity purposes on September 4, 2025.
