                       Sulfur Dioxide
•   On June 2, 2010 EPA revoked the two existing primary standards of
    140 ppb (24-hr) and 30 ppb (annual) and replaced them with a 1-hr
    standard of 75 ppb.

•   Currently MDEQ has two monitors:
    - Jackson County
          2008-2010 1-Hour Design Value – 35 ppb
    - N-Core Monitoring Site – started January 2011

•   EPA guidance document requires states to do both modeling as well as
    monitoring to classify areas as attainment/nonattainment.

•   Governor’s Recommendation was submitted on July 5, 2011,
    recommending Jackson County designated as attainment and the rest
    of the State as attainment/unclassifiable

•   Designations may be made in June 2012

•   Infrastructure SIPs are due by June 2013.
                                                                           9
       Carbon Monoxide
• On January 28, 2011, EPA proposed to
  retain the existing standard of 35 ppm
  (1 hour) and 9 ppm (8 hour).
• Final rule to be issued by August 12,
  2011
• MDEQ has a monitor at the N-Core
  Monitoring Site – started January 2011

                                           10
      Radnet Monitoring

    MS DEQ Rule Changes

       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.

                                                                             13
