## Abstract

The EPA is making a finding concerning whether or not each State has submitted a complete State Implementation Plan (SIP) that provides the basic program elements specified in Clean Air Act (Act or CAA) section 110(a)(2) necessary to implement the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS). By this action, EPA is identifying those States that: Have failed to make a complete submission for all requirements; have failed to make a complete submission for specific requirements; or have made a complete submission. The findings of failure to submit for all or a portion of a State's SIP establish a 24-month deadline for EPA to promulgate Federal Implementation Plans (FIPs) to address the outstanding SIP elements unless, prior to that time, the affected States submit, and EPA approves, the required SIPs. The findings that all, or portions of a State's SIP submission, are complete establish a 12-month deadline for EPA to take action upon the complete SIP elements in accordance with section 110(k).
