Approval and Promulgation of Implementation Plans; Region 4 States; 2008 Lead, 2008 Ozone and 2010 Nitrogen Dioxide Prevention of Significant Deterioration Infrastructure Plans

الملخص

The Environmental Protection Agency (EPA) is proposing to approve portions of submissions from Alabama, Florida, Georgia, Kentucky, Mississippi, South Carolina and Tennessee for inclusion into each State's implementation plan. This proposal pertains to the Clean Air Act (CAA or Act) infrastructure requirements for the 2008 Lead, 2008 Ozone and 2010 Nitrogen Dioxide (NO 2 ) National Ambient Air Quality Standards (NAAQS). The CAA requires that each state adopt and submit a state implementation plan (SIP) for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA. These plans are commonly referred to as "infrastructure" SIPs (hereafter referred to as "infrastructure SIP submissions"). Specifically, EPA is proposing to approve the portions of the submissions from Alabama, Florida, Georgia, Kentucky, Mississippi, South Carolina and Tennessee that relate to the infrastructure SIP prevention of significant deterioration (PSD) requirements. All other applicable infrastructure requirements for the 2008 Lead, 2008 Ozone and 2010 NO 2 NAAQS associated with these States are being addressed in separate rulemakings.
