NAAQS and Regional Haze Updates
Status for Region 4 1997 8-Hour Ozone Areas
• Only two remaining
nonattainment areas in
Region 4 (Atlanta & North
Carolina portion of
Charlotte).
• Atlanta & North Carolina
portion of Charlotte
proposed for redesignation.
• Critical for actions was
resolution of reasonably
available control technology
requirements, & approval of
baseline emissions inventory
& emissions statement SIPs.
2008 8-Hour Ozone NAAQS Implementation
6
• Final ozone implementation
rule expected Spring 2014.
• Emissions inventory &
emission statement
submissions due 2 years after
designations.
- clean data determination
does not relieve these
requirements.
- areas cannot be
redesignated without these
requirements being met.
Status for Region 4 1997 Annual PM2.5 Areas
• All areas appear to be
attaining the NAAQS.
• Five of the thirteen areas
redesignated to attainment.
• Good monitoring data
quality & resolution of any
data issues critical for
actions.
• Resolution of issues that
arouse from litigation for
the PM2.5 implementation
rule was necessary also to
move actions forward.
Status for Region 4 2008 Lead NAAQS Areas• Three areas designated
nonattainment & one area designated
unclassifiable.
• All required submissions provided by
Region 4 states.
• TN only required to provide emissions
inventory submission because Bristol
attaining & EPA completed clean data
determination for the Area.
• AL & FL required to provide
attainment demonstration submission
which included emissions inventories,
RACT, RACM & RFP in addition to
attainment modeling.
2010 Sulfur Dioxide Nonattainment Designations
• Nonattainment designations
completed August 5, 2013 –
effective October 4, 2013.
• Five areas in Region 4 as
part of the 29 nonattainment
areas designated nationally.
• Attainment SIPs due August
6, 2015.
• Attainment dates as
expeditiously as practicable
but no later than October 4,
2018.
Status of Region 4 Actions – Initial Regional Haze SIPs
Limited approval/limited approval completed for AL, GA, KY, MS, NC, SC & TN.
Full approval completed for FL – source by source BART & RP conducted (no reliance on CAIR or CSAPR).
Outstanding FIP clocks going for AL, NC & MS.

SIP Planning
SIP Processing in Region 4In FY13, processed 68 actions – 52 (47 processed
& 5 withdrawn) were backlogged (accounts for 17 consent decree deadlines met).
Enhanced communications for issue resolutionRegion 4 has active role on national workgroups to stay
informed of emerging issues.Conscious effort to alert states & regional management as
soon as issues emerge in attempt to quickly resolve issues.
Using quarterly & monthly calls to keep states informed.
FY 2014 Priorities
Challenges for FY 2014Balancing priorities with tighter EPA resources & catching up from impacts of
the shutdown.
Meeting CD & statutory SIP processing deadlines Designations State/local priorities
Managing impacts of litigation & petitions on upcoming actions
Tools for communication
SIP tracking log Early communications on priority SIPs (predrafts still welcomed!) Will be important for states to continue to communicate priorities to state contact
or RDS chief on monthly calls.

Data Requirements Rule: Establishes requirements for state submittals of modeling or monitoring data in

Proposed Rule – April 2014*
Final Rule - April 2015* *Dates subject to change.
Regional HazeProgress Report SIPs & Adequacy Determinations:
Due five years after submittal of initial regional haze SIP.
April 2013 – EPA issued a document to assist EPA and States in the development and review of the progress SIPs.
R4 SIP Status:
Final SIPs = SC, NC, TN Prehearings under review = GA Draft SIPs reviewed = KY
2018 Regional Haze SIPs:
Due July 31, 2018.
Informal listening sessions on regional haze program and regulations ongoing.
Groups provided recommendations to:
improve program and identify what changes may be needed to implement recommendations.
Startup, Shutdown and Malfunction Provisions Proposed SIP Call for 36 states and 7 local agencies was published February
22, 2013.
During an 80-day public comment period, including a public hearing on March 12, 2013, EPA received over 35,000 supportive comments from citizens and environmental groups and nearly 200 adverse comments from state/local air agencies and industry.
Any further comments on the proposal or discussions with EPA must be recorded and entered into the public rulemaking docket.
On September 26, 2013, EPA and the Sierra Club agreed to extend the deadline for finalizing the rule to May 15, 2014.
