Summary

The Environmental Protection Agency (EPA) is proposing to approve, in part, and disapprove in part, portions of the State Implementation Plan (SIP) submission, submitted by the State of Mississippi, through the Mississippi Department of Environmental Quality (MDEQ), on December 11, 2015, to demonstrate that the State meets the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2012 annual fine particulate matter (PM ^2.5 ) national ambient air quality standard (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an “infrastructure” SIP. MDEQ certified that the Mississippi SIP contains provisions to ensure the 2012 Annual PM ^2.5 NAAQS is implemented, enforced, and maintained in Mississippi. With the exception of the state board majority requirements respecting significant portion of income, for which EPA is proposing to disapprove, EPA is proposing to determine that portions of Mississippi's infrastructure submission, submitted to EPA on December 11, 2015, satisfy certain required infrastructure elements for the 2012 Annual PM ^2.5 NAAQS.
