• Lime spray dryer baghouse is used to control PM and SO2 emissions
• Permit requires the installation of PM10, PM2.5, SO2, and Volatile Organic HAP ambient monitors at two sites near the plant
• Community Advisory Panel has been set-up and has met three times already
Middletown Coke
• Permit Appeal– Compliance Certification– Emission Offsets/Credits– Inserting Emission Credits back into Inventory
Area Source MACT Standards
• Over 20 Area Source Standards promulgated during the past three years
• Places additional requirements on smaller emitting sources
• May impact sources previously exempt from permitting
Area Source MACT Categories
• Paint Stripping• Miscellaneous Surface Coating (Targeted HAP
– PM not VOC)• All Motor Vehicle Coating Operations• Plating and Polishing• Metal Fabrication – Various Categories• Chemical Manufacturing – Various Categories• Reciprocating Internal Combustion Engines
Area Source MACT Guidance
• On August 5, 2010 Ohio EPA provided guidance for implementing Area Source MACT’s– Ohio EPA has not accepted delegation of the
recent area source MACT standards– Adding a permit term that states an area source
MACT may apply– U.S. EPA will be responsible for enforcement of
the rule
Area Source MACT Guidance
– De Minimis determinations are done without considering the area source MACT’s
– Area Source MACT does not affect permit exemption determinations in OAC rule 3745-31-03
– DO/LAA are not responsible to perform inspections for area source MACT’s
– Initial notifications should be sent to U.S. EPA with Ohio EPA Central Office and DO/LAA copied
Area Source MACT Requirements
• Initial Notification • Notification of Compliance • Compliance Requirements• Annual Compliance Reports

Monitoring - NCore• Objectives
– Track long term trends• Emissions control program accountability• Health Assessments for NAAQS review
– Support development of emission control strategies
• Air quality model evaluation
– Provide data for • attainment/nonattainment determination• Real time reporting of data to public/forecasting for
AQI
– Support scientific studies– Support Ecosystem assessments
Monitoring - NCore• NCore
– National Core Monitoring Sites• ~80 sites nationwide both urban and rural• Parameters
– NOy - trace/precursor– SO2 - trace/precursor
– CO - trace/precursor– Ozone– Pb - proposed to be in effect 1/2012– PM2.5 - Filter/mass and Continuous– PM2.5 Speciation– PM 10-2.5 – Filter/mass
– PM 10-2.5 - Speciation
– Met: ws/wd, relative humidity, temperature
Additional Monitoring• 5 year network assessment
– http://www.ladco.org/reports/general/Regional_Network_Assessment/index.html
– PAMS monitoring re-visited• Higher design value ozone sites have shifted regionally• PAMS –like Monitoring
– Regionally testing THC and BTEX monitors– Recommendation to add NOx at one downwind site -
Lebanon or Sycamore
