Air Permitting Update
April 16, 2013
Eric Cornwell
Stationary Source Permitting Program
SSPP Structure
• 4 Units - 28 permit engineers, 2 admin
– Chem Unit – Glass, engineered wood
– NOx Unit – Landfills, engines
– VOC Unit – Wood pellets, lumber kilns
– Min Unit – Military, rendering, asphalt
Permit Application
Timeliness:
• Pending Application Count (April 2013):
– 202 permit applications
– 12 (non TV-renewal) apps older than six months
– 500 permit apps processed in past 12 months
• Processing time
– Title V significant modifications……161 days
– 502(b)10…………………………….…...66 days
– Synthetic Minor…………………..……62 days
Expedited Permits
• In response to Senate Bill 427  O.C.G.A 22-2(c)(1)(A).
• Implemented no later than July 1, 2013
• Two stakeholder meetings (Oct and Dec)
• http://www.georgiaair.org/airpermit/html/sspp

Expedited Permits, Cont.
• No rulemaking – Director to implement
procedures.
• Fee-based and optional for applicants
• Reviews done by EPD – no third party review
• TV-I, TV-R, MAWO not eligible
PSD Resources
• PSD Guidance for Industry – now available
• Pre-processed met data – now available
• Background ambient concentrations – now
available
• Statewide NAAQS and PSD Increment inventory
(aka Off-site Emissions inventory)
– Not yet…EPD intends to do this if funding is
available
PSD Guidance for Industry
• Provides up-front expectations for a
complete PSD application
– BACT, Modeling, Submittals
– Emphasizes early resolution of issues.

Meteorological Data
• GA EPD has developed 5-years of
meteorological data for each ASOS surface
and upper air pairing
– Pairing based on distance, climatological zone, and data
completeness criteria
– Last updated on April 4, 2013
• All data sets are available on-line

Surface Roughness Update
• Previously, EPD provided data sets with three different
surface roughness values (0.05, 0.5, 1.0) and the
applicant ran AERSURFACE at the project site to find
the most representative value.
• Now, meteorological data is processed using the
surface roughness at the airport
– 12 different sectors
• Applicant will provide a justification for
representativeness in modeling protocol

Background Concentrations
• GA EPD has develop background
concentrations for each county based on the
2009-2011 design values
– PM10, PM2.5, SO2, NO2, CO, Pb
• Will update to 2010-2012 design values by
the end of April
• All data sets are available on-line

Permit Modeling Guidance
• Guideline for Modeling PM10 Ambient
Concentration in Areas Impacted by Quarry
Operation Producing Crushed Stone - August 7,
2012

GHG Permitting
• July 20, 2014 – Biomass deferral set to end.
– GHG-major sources with non-PSD permits must
“begin actual construction” prior to this date;
otherwise permit invalid.
• US EPA has recently proposed revised
“Global Warming Potential (GWP) for Part 98.
78 FR 19809, Table 2
Boiler MACT and GACT
• Final standards published in FR Feb 2013
• SSPP slowly rolling details into permits

Adding to already pending applications
Companies can request revisions
Conditions as specific as practical
No mass “open for cause”
Wood Pellet Emission Factors
• Process – Log chipper, dryer (usually directcontact), hammermill, pelletizer, and pellet cooler.
• Downstream testing showed VOC previously
unaccounted for.
– Plants over ~120,000 tpy production may be PSD major
without downstream controls.
• Manny Patel developed default wood pellet
emission factors from AP-42 and testing
EPD switching email systems
– Novell to Outlook
– Air Branch transition this week
– Email addys to remain the same
