Summary

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving elements of a State Implementation Plan (SIP) submission from the State of Oklahoma for the 2012 Fine Particulate Matter (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS or standard). The submission addresses how the existing SIP provides for implementation, maintenance, and enforcement of this NAAQS (infrastructure SIP or i-SIP). The i-SIP ensures that the Oklahoma SIP is adequate to meet the State's responsibilities under the CAA.
