Findings of Failure To Submit a Complete State Implementation Plan for Section 110(a) Pertaining to the 2008 Lead National Ambient Air Quality Standards

The EPA is finding that seven states have not made complete state implementation plan (SIP) submissions to address certain SIP elements, as required by the Clean Air Act (CAA). Specifically, the EPA is determining that these seven states have not submitted complete SIPs that provide the basic CAA program elements necessary to implement the 2008 lead national ambient air quality standards (NAAQS). The EPA refers to these SIP submissions as "infrastructure" SIPs. Of the seven states, three are incomplete only due to prevention of significant deterioration (PSD)-related elements, for which a federal implementation plan (FIP) is in place. The remaining 43 states have made complete submissions. Each finding of failure to submit establishes a 24-month deadline for the EPA to promulgate FIPs to address the outstanding SIP elements unless prior to the EPA promulgating a FIP an affected state submits, and the EPA approves, a SIP that corrects the deficiency.
