## Abstract

The EPA is today making a finding that States have failed to submit State Implementation Plans (SIPs) to satisfy the requirements of section 110(a)(2)(D)(i) of the Clean Air Act (CAA) for the 8-hour ozone and PM2.5 (particles with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers) National Ambient Air Quality Standards (NAAQS). Section 110(a)(1) of the CAA requires that States submit SIPs to meet the applicable requirements of section 110(a)(2) within 3 years after the promulgation of a new or revised NAAQS, or within such shorter period as EPA may provide. Pursuant to section 110(a)(1), States are required to submit SIPs that satisfy the requirements of section 110(a)(2)(D)(i) related to interstate transport of pollution. At present, States have not yet submitted SIPs to satisfy this requirement of the CAA, and EPA is by this action making a finding of failure to submit which starts a 2-year clock for the promulgation of a Federal Implementation Plan (FIP) by EPA unless, prior to that time, each State makes a submission to meet the requirements of section 110(a)(2)(D)(i) and EPA approves such submission.
