## Abstract

The EPA is making a finding that certain states, the District of Columbia, and the Commonwealth of Puerto Rico have not submitted a complete State Implementation Plan (SIP) that addresses basic program elements of the Clean Air Act (CAA or Act) necessary to implement, maintain, and enforce the 2006 24-hour Fine Particulate Matter (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS). The EPA refers to these SIP submissions as "infrastructure" SIPs, because they address basic structural requirements specified in section 110(a)(1) and (2) that states must establish that they meet following the promulgation of a new or revised NAAQS. Specifically, the EPA is evaluating whether these states, the District of Columbia, and the Commonwealth of Puerto Rico made complete infrastructure SIP submissions to address the applicable requirements of section 110(a)(2)(A) through (M) necessary to implement the 2006 PM<INF>2.5</INF> NAAQS, with the exception of section 110(a)(2)(I), portions of section 110(a)(2)(C) pertaining to nonattainment area requirements and section 110(a)(2)(D)(i)(I). By this action, the EPA is identifying those states, the District of Columbia, and the Commonwealth of Puerto Rico that have failed to make a complete submission for some or all of these specific requirements. The finding of failure to submit for some or all of these specific elements establishes a 24-month deadline for the EPA to promulgate a Federal Implementation Plan (FIP) to address each state's outstanding infrastructure SIP elements unless, prior to that time, the state submits, and the EPA approves, a submission that meets the required elements, or unless the state is already subject to an existing FIP that addresses the SIP deficiency.
