New EPA tools for nonattainment and maintenance areas for the National Ambient Air Quality Standards (NAAQS)
March 25, 2021, EPA released three new online tools that provide information about nonattainment and maintenance areas for the National Ambient Air Quality Standards (NAAQS). These tools will replace the nonattainment and maintenance area information currently provided at EPA’s SIP Status Reports.
- The Nonattainment and Maintenance Population Tool displays the number of people living in designated nonattainment and maintenance areas for current and revoked NAAQS, based on 2019 population.
- The Nonattainment and Maintenance Area Dashboard provides information about nonattainment and maintenance areas for current and revoked NAAQS.
- The Required State Implementation Plan (SIP) Elements Dashboard provides details about individual states’ Clean Air Act and regulatory planning requirements associated with implementing, attaining, and maintaining the NAAQS through SIPs.
