Air Pollution Grab Bag

Middletown Coke

• Produce coke from coal which will be used by AK Steel to produce iron

• Facility will have 100 ovens and produce 550,000 tons of coke per year

• Generate electricity from the waste gas• Construction is approximately 21% complete• Anticipated start-up date – September 1, 2011

Middletown Coke

• Initial permit application submitted in February 2008 (“Netting” permit)

• Final Permit issued November 2008• Major New Source Review permit application

submitted in April 2009• Final Permit issued February 2010

Middletown Coke

• 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 -
