12. MS DEQ Rule Changes • SIP Revision and amendments to state air pollution control regulations and State Title V regulations to adopt, by reference & incorporate federal requirements specifically, the Tailoring Rule for Greenhouse gases. • .

13. MS DEQ Rule Changes • SIP Revision and amendments to “Regulations for the Prevention of Significant Deterioration of Air Quality”, APC-S- 5 to adopt, by reference, incorporate federal provisions relating to implementing the New Source Review(NSR) program for fine particulate matter (PM2.5) • The Commission adopted the regulation amendments on April 28, 2011. • Depending upon the final action from US EPA, we proposed to address NOx as a PM2.5 precursor as follows: 1. Until such a time where EPA takes action on the demonstration or upon plan disapproval, NOx will be considered as a precursor for PM2.5 in Mississippi. Or 2. Upon EPA approval of this demonstration, NOx will not be considered as a precursor for PM2.5 in Mississippi.
