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& 5 withdrawn) were backlogged (accounts for 17 consent decree deadlines met).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.

2010 SO2 NAAQS ImplementationTechnical Assistance Documents (TADs) Modeling and Source-Oriented Monitoring TADs Provide technical advice on the use of modeling and monitoring to determine if areas

are meeting the SO2 standard. Draft comment period opened May 21, 2013, and closed July 22, 2013. EPA is addressing comments for another update to be issued in the next few months.

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

support of phase 2 designations. Proposed Timeline for Rulemaking:

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.
