Nonattainment Area - Particulate Matter - 2.5 24 hr (2006 Standard)

Description

The Nonattainment Area - Particulate Matter-2.5 24 hr (2006) dataset was updated on November 30, 2025 by the Environmental Protection Agency (EPA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This dataset provides detailed information about areas identified in the U.S. where 24 hour (daily) particulate matter (PM2.5) levels have not met the National Ambient Air Quality Standards (NAAQS) established in 2006 for particulate matter (PM2.5) and have been designated "nonattainment areas (NAA)". These data are weekly from an OAQPS internal database. However, that does not necessarily mean the data have changed. For more information about this non-attainment area, please see the website https://www.epa.gov/green-book/green-book-pm-25-2006-area-information.
