Ohio Air Monitoring Network 2011-2012 6/17/11

Requirements

As required by 40 CFR 58.10, Ohio EPA is providing an annual monitoring network plan for 

public review and comments. Ohio EPA will submit this plan with comments to the US EPA 

Region V Regional Administrator. There will be a 30 day comment period for the public to 

make comments on the plan and those comments will also be submitted to Region V. The 

Ohio Air Monitoring Network as it exists as of July 1, 2011 is included in the accompanying 

table. 

Changes

The plan for Ohio’s Air Monitoring Network for 2011-2012 is to make changes as required 

or necessary for the air monitoring network. In 2011 Ohio and other states were required to 

consider additional lead sampling sites based upon modeling results of Ohio facilities with 

emissions of one half-ton of airborne lead emissions per year. The results of that modeling 

and the requests for waivers from sampling are included in a separate report under Ohio Lead 

Monitoring Plans 2011-2012 at:

http://www.epa.state.oh.us/portals/27/ams/plans/OhioLeadMonitoring.pdf

The Lead Monitoring Plans were made available to the public on May 11, 2011 for review 

and comment.

For sites that monitor for very fine particulate matter or PM2.5, Ohio EPA expects to 

continue with monitoring or sampling for the PM2.5 Federal Reference Method at most of 

the sites as they existed at the beginning of 2011. Some changes that are not noted in these 

plans that will be posted by July 1, 2011 could occur based upon the change in funding from 

103 funds to 105 funds. Some Ohio local air agencies and the state district office PM2.5 

sampling may result in fewer sites or monitors to operate because of reduced funding 

availability. 

The ozone monitoring sites will have only a few changes for 2011. While we anticipate that 

the NAAQS for ozone will be made more stringent in 2011 an analysis of ozone sites made 

by the Lakes Area Director’s Consortium (LADCO) in 2010 shows that Ohio already has 

more than enough ozone monitoring sites to cover current requirements. 

The LADCO analysis showed that PM10 sampling in Ohio has more than adequate coverage. 

Reductions for PM10 could be made in Ohio although it is recognized that significant 

reductions in costs won’t result from PM10 site and sampler reductions.

Changes occur to the network each year that are unplanned. Changes or temporary 

interruptions of sampling may occur because of events such as building or roof maintenance, 

construction, change of ownership of the site or other changes at the site that require moving 

the instruments. Some changes that are planned may include adding additional sites for 

complaint areas or for some new or proposed facility. Other changes that are planned may 

not actually happen because a new site cannot be secured or because of budget constraints.
New Federal requirements for monitoring for sulfur dioxide, nitrogen dioxide and carbon 

monoxide air pollutants were set in 2009. These requirements will not take effect in 2012 

but will take effect January 1, 2013. Those requirements include near-roadside monitors for 

NO2 at 6 sites in Ohio plus 2 additional ozone sites and several sites for SO2 in specific 

counties named by US EPA. Again those are plans that will need to be determined in 2012 

for set-up in 2013.

Three new National Core Monitoring Network (NCORE) sites have started operating in Ohio 

in recent years in Cincinnati, Cleveland and Dayton agency jurisdictions. These NCORE 

sites monitor for sulfur dioxide, nitrogen oxides and carbon monoxide at trace concentration 

levels were required to start January 1, 2011 but all started earlier than that date. Those sites 

will add lead samplers to their sites to begin January 1, 2012.

All site and parameter changes are made in consultation with and approval of the US EPA 

Region 5 air monitoring staff.

Guidance and Priorities

Ohio EPA follows the federal general guidance for air monitoring according to 40 CFR 58 

Appendix D to monitor in areas of 1) expected high concentrations, 2) areas of high 

population density, 3) areas with significant sources, 4) general background concentration 

sites and 5) areas of regional transport of a pollutant. Not all air pollutants have sites for all 

of these categories. 

In addition to the above guidance in 2010 the Air Directors in the Region 5 states of Ohio, 

Michigan, Indiana, Illinois, Wisconsin and Minnesota listed air monitoring objectives as:

1) Areas of high concentration and high population, provide timely air quality data to 

the public, support compliance with NAAQS and control strategy development and 

support air pollution research studies 

2) Multi-pollutant monitoring such as the NCore sites

3) Source-oriented monitoring such as required monitoring for lead, nitrogen dioxide 

and sulfur dioxide

4) Rural monitoring and medium size city monitoring

5) Environmental justice monitoring

6) School air toxics monitoring 

An important consideration of all air monitoring projects and sites is that funding resources 

be available to operate and maintain the sites and equipment, to provide sample analyses and 

for data collection and reporting. An important funding change coming for very fine 

particulates or PM2.5 is that the funding is changing from a Section 103 grant that is fully 

federally funded to a partial Section 105 grant that requires a state or local agency matching 

amount. This change may limit the types and numbers of PM2.5 sampling that the state or 

local is able to support. Current plans are for funding in 2012 at 75% Section 103 funding 

and 25% for Section 105 funding.
As of the time of publication of this list Ohio EPA plans to discontinue monitoring or has 

already discontinued monitoring at locations as shown in the table at: 

 3 very fine particulate matter or PM2.5 sites, Akron (2), HCDES 

 1 ozone site, Akron

 1 CO site, Akron

 1 SO2 site, Akron

 1 NO2 site, Akron

 1 carbonyl toxics site, CDO

 6 PM10 industrial sites, NWDO 

Ohio EPA has moved or started sites and instruments for:

 4 PM2.5 sites, 1 Portsmouth, 1 Lake, 1 MTAPCA, 1 Toledo

 3 PM2.5 FRM sites, Akron, MTAPCA, Lake

 3 PM2.5 continuous sites, Cleveland, MTAPCA, Lake 

 2 PM10 sites, Cleveland, Portsmouth

 4 sulfur dioxide sites, Portsmouth, SEDO 3, Portsmouth

 2 ozone sites, Akron, Portsmouth

 2 TSP for metals sites, Cleveland, MTAPCA

 3 NCore sites, Cleveland, HDCOES, RAPCA

For new requirements from July , 2009 for sulfur dioxide monitoring sites to be in place by 

January 1, 2013 Ohio EPA has tentative plans to either continue SO2 monitor monitoring 

sites or add/ restart new SO2 monitoring sites as follows:

2 sites in Cincinnati to continue

2 sites in Cleveland to continue

1 site operated by West Virginia to continue, 1 SO2 monitor in 

Marietta/SEDO may be added

1 site to continue in Steubenville

1 site to be added or restarted in Columbus

1 site to be added or restarted in Toledo 

 1 site to be added or moved near Point Pleasant/SEDO

1 site to be added or restarted in Dayton

1 site to continue in Akron

Depending upon new monitoring requirements for ozone sites to be in place possibly in 

2013, Ohio EPA has tentative plans to add ozone monitoring sites as follows:

1 site in Mansfield/NWDO

1 site in Sandusky/NWDO

These plans are dependent upon securing adequate levels of funding to support the changes 

to the air monitoring network. All of the plans are subject to approval by US EPA.

Notes/Explanations: 

AQS is the Air Quality System maintained by US EPA for air quality data. In the AQS ID# the first 2 digits refer to the state. 39 is Ohio. The next 3 

digits are the county within Ohio. The last 4 digits designate a specific site within the county. 

All PM2.5 Seq. FRM sites, BGI FRM sites and BAMS sites are comparable to the PM2.5 NAAQS.

All Ozone sites are comparable to the NAAQS.

All sulfur dioxide, carbon monoxide and nitrogen dioxide sites are comparable to the NAAQS.

PM is Particulate Matter. PM10 means particulate matter of 10 microns in diameter or smaller. A micron is one millionth of a meter. 
PM2.5 is particulate matter 2.5 millionths of a meter in diameter or smaller. PM10 is fine particulate matter and PM2.5 is very fine particulate matter. 

Monitoring instruments used for comparing to the National Ambient Air Quality Standards are designated as Federal Reference Methods (FRM) or 

Equivalent Methods. 

PM2.5 Seq. FRM are samplers that sample for PM2.5 can hold multiple samples for Sequential sampling and are Federal Reference Methods (FRM).

Colocated or colo indicates a site with duplicate samplers for Quality Assurance purposes. Data is statistically compared from the two samplers for the 

same days. Duplicate samplers may sample at a I in 6 day schedule or possibly at a 1 in 12 day schedule.

Chem. Speciation sites are sites and samplers that collect PM2.5 samples that are analyzed for the chemical speciation make-up of the PM2.5 particulate 

matter. 

U.V. Photometric indicates ultra-violet photometric, a method of detection for ozone concentrations.

U.V. fluorescence indicates ultra-violet fluorescence, a method of detection for sulfur dioxide concentrations.

VOCs are Volatile Organic Compounds. The method of collecting and analyzing whole air samples for VOCs is in Ohio is TO-15. The collection 

utilizes a stainless steel canister for subsequent analysis by gas chromatograph -mass spectrometer. There are approximately 72 compounds scanned for 

in the analysis. 

TSP – metals is the method of collecting Total Suspended Particulate by drawing an air sample through a filter media that is then analyzed at a laboratory 

for airborne metals including lead, arsenic, cadmium, chromium, nickel, zinc, manganese and beryllium and sometimes particulate mercury. Analysis is 

by ICP or Inductively Coupled Plasma Emission Spectroscopy or Graphic Furnace Atomic Absorption. 

BAM indicates a Beta Attenuation Monitor, a method of detection for very fine particulates.

TEOM indicates a Tapered Element Oscillating Microbalance, a method of detection for very fine particulates.

SIP is State Implementation Plan that details how the state will implement controls that will bring the area into attainment status for a particular National 

Ambient Air Quality Standard. Chemical speciation sampling and analysis for PM2.5 aids helps to determine what control measures and plans will best 

control fine particulates.

Ohio Lead Air Monitoring Network 2011-2012 

Notice is hereby given that the Director of the Ohio Environmental Protection Agency, 

(Ohio EPA) as required by 40 CFR 58.10 is making the Lead Air Monitoring Network 

2011-2012 plans for ambient air monitoring available for a 30-day public comment 

period. The plans include the new sampling network for monitoring airborne lead based 

upon the revised National Ambient Air Quality Standard for lead with added plans for 

facilities with 0.5 ton per year of lead emissions. The new standard for lead of 0.15 

micrograms per cubic meter of air as a rolling 3-month average required a US EPA 

approved lead monitoring network that began sampling January 1, 2010. All plans for 

the monitoring of lead, sulfur dioxide, carbon monoxide, nitrogen dioxide, ozone and 

fine particulates are subject to approval by the United State Environmental Protection 

Agency (U.S. EPA). 

These air monitoring plans must be noticed to allow public comment and to satisfy U.S. 

EPA requirements for public involvement in air monitoring activities. This notice 

addresses Ohio EPA’s reliance on air monitoring as evidence of attainment and 

maintenance and the commitment to institute contingency measures if ambient 

exceedances or violations trigger the contingency plan requirements. Written 

comments will be received on or before June 11, 2011 at the following address:

Ohio Lead Monitoring Plans 2011-2012 

The US EPA issued a new National Ambient Air Quality Standard (NAAQS) for airborne 

lead in 2008. The new lead standard is set at 0.15 ug/m3 as a rolling 3-month average. 

As a result of that action Ohio EPA, district offices, and contractual agencies 

implemented a new lead monitoring network of seven required samplers on January 1, 

2010. Those seven sites were at locations near facilities that were modeled by the Ohio 

EPA Division of Air Pollution Control State Implementation Plan (SIP) Section as 

discussed in the following Revised Lead Monitoring Network 2011-2012. Site 

information about the initial seven samplers that began sampling in early 2011 is 

included in this notice. 

US EPA has determined an additional need for facilities with emissions over 0.5 ton per 

year (tpy) to be modeled for possible impacts of airborne the lead. The SIP Section has 

modeled facilities with emissions exceeding 0.5 tpy of lead. The results of the modeling 

at three facilities in Ohio are specifically discussed in the Revised Lead Monitoring 

Network 2011-2012. 

In addition to the identified facilities with lead emissions of over 0.5 tpy there are three 

new National Core Monitoring (NCore) Stations in Ohio to sample for airborne lead. 

The contractual agencies in Hamilton County (HC DES), Montgomery County (Regional 

Air Pollution Control Agency) and Cuyahoga County (Cleveland Department of Public 

Health, Division of Air Quality) are operating NCore sites. Lead sampling is one of the 

requirements for NCore monitoring sites and required to start on or before December 

27, 2011. 

Agencies with NCore sites that are located in areas not likely to show significant lead 

concentrations are permitted to request to move the required sampler to a location more 

likely to show measureable lead concentrations. The main RAPCA NCore site is located 

in rural Preble Co. The RAPCA agency has already sought and was granted permission 

to set up a lead site in Moraine in Montgomery County. 

Details of the locations of the NCore lead sites follow the information about the facilities 

in Ohio that have more than 0.5 tpy of lead emissions.

Revised Lead Monitoring Network 2011-2012 

As part of implementation of the newly revised 2008 National Ambient Air Quality 

Standards for lead, the lead monitoring network was revised and expanded beginning in 

2010. Beginning in 2010, facilities with emissions of lead greater than one ton per year 

(tpy) were required to be monitored and facilities with emissions of lead greater than 0.7 

tpy were required to be modeled to determine if they impacted 50% of the new lead 

standard. If these sources did impact 50% of the new lead standard they also required 

a monitor. U.S. EPA did provide a waiver option for a facility emitting over one tpy. If 

the state performed modeling to show the source would not impact 50% of the new land 

standard, a waiver could be submitted for the monitoring requirement. The new lead 

standard was set at 0.15 ug/m3. 

On December 14, 2010 U.S.EPA finalized rule changes to again expand the nation's 

lead monitoring network to better assess compliance with the 2008 lead standard. U.S. 

EPA is now requiring all facilities with emissions of lead greater than 0.5 tpy to be 

monitored. U.S. EPA also retained the option for the state to perform modeling and 

submit a waiver for these sources, if applicable. This section will discuss Ohio EPA’s 

proposed revised lead monitoring network, as it relates to facility specific monitoring of 

lead emissions. 

As a part of this effort, Ohio EPA began an extensive review of lead emissions 

inventories. Based on the inventories, Ohio EPA consulted with several facilities 

regarding their reporting history. In some cases Ohio EPA found discrepancies where 

facilities have reported erroneously. Because the facility based lead monitoring network 

is based upon actual lead emissions from Ohio sources, it was essential to gather 

accurate information regarding lead emissions in order to effectively develop the lead 

monitoring network. Once Ohio EPA finalized the accurate emission inventories, any 

source (not already monitored) with lead emissions greater than 0.5 tpy were selected 

for modeling1

 to determine if their impact on ambient air would necessitate a monitor. 

This section contains a discussion of the results of this modeling and the determination 

as to whether a monitor would be necessary. 

Ohio EPA found three facilities with lead emissions exceeding 0.5 tpy, not currently 

being monitored. All information regarding the modeling performed by Ohio EPA can be 

found in the attached waiver request (see page 6). 

                                                            

1 Unless otherwise noted, all modeling was based upon the highest emissions rates that correspond to the highest

ton per year emissions reported, in either the National Emissions Inventory or the Toxic Release Inventory, by the

facility between 2007 and 2009, as guided by USEPA.

National Core Monitoring Stations Lead Sampling 

In addition to sampling for lead near facilities with lead emissions, there is a requirement 

for airborne lead sampling at National Core Monitoring Stations (NCore). There are 

three NCore sites in Ohio; The Hamilton County Division of Environmental Services 

operates one NCore site in Hamilton County, The Regional Air Pollution Control Agency 

(RAPCA) in Dayton operates one site in Preble County, and the Cleveland Department 

of Public Health, Division of Air Quality operates one site in Cuyahoga County. 

Agencies with NCore sites that are located in rural areas of anticipated low lead 

concentrations may request permission through the Regional Director to move the 

required monitor to a location more likely to detect lead concentrations. The RAPCA 

NCore site is located in rural Preble Co. The RAPCA agency has already sought and 

was granted permission to locate their required lead site in Moraine in Montgomery 

County. 

Details of the locations of the NCore lead sites follow the information about the facilities 

in Ohio that have more than 0.5 tpy of lead emissions. The lead sampling at NCore 

sites are required to start on or before December 27, 2011. If possible those sites will 

begin in November in order to obtain a complete 2012 sampling year with a 3-month 

rolling average beginning in January 2012.

Re: Request for Lead Monitoring Waivers near Ohio Industrial Sources 

On November 12, 2008, U.S. EPA substantially strengthened the National Ambient Air 

Quality Standards (NAAQS) for lead by revising the level of the primary standard from 

1.5 ug/m3 to 0.15 ug/m3. In conjunction with strengthening the lead standard in 2008, 

U.S. EPA promulgated new monitoring requirements including new design requirements 

for the lead monitoring network. Under this proposal, monitoring requirements stated 

there must be one source-oriented lead monitor located near each lead source that 

emits one or more tons per year (TPY) to measure the maximum contribution in ambient 

air, unless a wavier was granted by the U.S. EPA Regional Administrator. Ohio EPA 

submitted its monitoring plan at that time but did not submit any waivers under this 

original proposal. 

Subsequently, on December 27, 2010, U.S. EPA revised the original monitoring 

requirements from 2008. New monitoring requirements state there must be one sourceoriented lead monitor located near each lead source than emits 0.5 or more TPY to 

measure the maximum contribution in ambient air, unless a wavier is granted by the 

U.S. EPA Regional Administrator. According to 40 CFR Part 58, Appendix D, 

paragraph 4.5(a), a state may apply for a monitoring waiver if they can demonstrate that 

a particular source will not contribute to a maximum lead concentration (based on a 

maximum 3-month rolling average over three years of monitoring data) in ambient air in

2 In 2009 Ohio EPA and AEP Gavin responded regarding over reporting of historic lead emissions in the State EI.  

AEP Gavin clarified that the TRI values more accurately represent emissions due to a more robust calculation

method compared to that used in the State EI.  Beginning in 2008, AEP Gavin used the more accurate calculation

method in the State EI.  2005, 2006 and 2007 State EI emissions in the table above are corrected per previous

communications with U.S. EPA.

Table 2 – Source Parameters 

Modeling 

The sources were modeled using Beeline Software’s BEEST Model. This utilizes U.S. 

EPA’s American Meteorological Society/Environmental Protection Agency Regulatory 

Model (AERMOD) model, version 07026. All modeling was completed prior to the 

release of AERMOD version 11059. Surface data and upper air data from Huntington 

West Virginia (NWS Station 03860) were determined to be representative of the facility 

site. AERSURFACE was run using one sector and four seasons. All lead emission

sources are stacks. Table 2 shows all the modeled source parameters. Two receptor 

grids were modeled surrounding this facility. Receptor grid spacing is as follows: 100 

meters extending out 10km from the facility, and 200 meters extending out 16km from 

the facility. 

Modeling Results 

The lead post processor, written and provided by U.S. EPA, was used to calculate a 3-

month rolling average of the lead concentrations. AERMOD modeling output files were 

used as input files into the post processor. The overall maximum 3-month averaged 

concentration calculated by the post processor is 0.00 ug/m3 (maximum modeled 

monthly average impact at 0.0012 ug/m3). Due to the tall stacks, it is believed that 

modeled concentrations are so low due to great dispersement. This calculated 

concentration does not exceed 50% of the NAAQS. Figure 1 shows the maximum 

concentration and the concentration gradient surrounding the facility.

Regardless, to be conservative, a background value could be added to the results. The 

nearest monitor that would represent a background value is located in Washington 

County near R.H. Gorsuch power plant and the Eramet Marietta facility. This monitor 

would likely over-represent background in the AEP Gavin area. 

To determine an appropriate and conservative background value, Ohio EPA looked at 

the 3-month average concentrations from monitor 39-167-0008 (State Route 676, 

Washington Career Center, Marietta, OH) from 2008 to 2010. The 3-month average 

concentrations for each year were averaged and the highest of the three years was 

used as a background value. This value is 0.0073 ug/m3 (see the attached monitor 

summary for the computation). 

 

To be conservative, the maximum modeled monthly average impact was added to the 

background because rolling 3-month averages were too low for the U.S. EPA lead post 

processor to calculate. A total potential impact considering a conservative background 

value is seen in Table 3:

Modeling 

The sources were modeled using Beeline Software’s BEEST Model. This utilizes U.S. 

EPA’s American Meteorological Society/Environmental Protection Agency Regulatory 

Model (AERMOD) model, version 07026. All modeling was completed prior to the 

release of AERMOD version 11059. Surface data from the Youngstown Municipal 

Airport (NWS Station 14852) and upper air data from Pittsburgh, Pennsylvania (NWS 

Station 94823) were determined to be representative of the facility site. AERSURFACE 

was run using twelve sectors and four seasons. One receptor grid was modeled. 

Receptors were spaced 50 meters apart extending out 23 km, surrounding the facility. 

Modeling Results 

The lead post processor, written and provided by U.S. EPA, was used to calculate a 

three-month rolling average of the lead concentrations. AERMOD modeling output files 

were used as input files into the post processor. The overall maximum 3-month 

averaged concentration calculated by the post processor is 0.01ug/m3. The maximum 

modeled concentration was at 319077.00E, 4493219.00N, east north east of the facility.

facility. Six months of monitoring data from 2010 is available for this site. To be 

conservative, the highest monthly value during those six months will be used as a 

background value. This value is 0.0170 ug/m3 (see the attached monitor summary for 

the computation). 

 

The monitor at Ellwood Engineering, which is a 2.49 TPY lead source, was within the 

area of highest modeled concentration. Therefore, this should provide more than 

conservative results as a background for this site. 

Because there is limited data from the Ellwood Engineering monitor, an alternative was 

considered. There are three monitors located in East Liverpool, Columbiana County. 

These three monitors serve the area around the Von Roll facility. To determine an 

appropriate and conservative background value, Ohio EPA looked at the 3-month 

average concentrations from each of these monitors from 2008 to 2010. The 3-month 

average concentrations for each year were averaged and the highest of the three years 

was used as a background value. This value is 0.0166 ug/m3 (see the attached monitor 

summary for the computation) for monitor 39-029-0019. This monitor is located across 

from the Von Roll facility in East Liverpool. Predominant wind directions for this area 

indicates emissions from the Von Roll facility would blow directly towards the monitor, 

as shown in Figure 3.

Modeling 

The sources were modeled using Beeline Software’s BEEST Model. This utilizes U.S. 

EPA’s American Meteorological Society/Environmental Protection Agency Regulatory 

Model (AERMOD) model, version 07026. All modeling was completed prior to the 

release of AERMOD version 11059. Surface data from the Cleveland International 

Airport (NWS Station 14820) and upper air data from Buffalo, New York (NWS Station 

14733) were determined to be representative of the facility site. AERSURFACE was 

run using twelve sectors and four seasons. Two receptor grids were modeled 

surrounding this facility. Receptor grid spacing is as follows: 100 meters extending out 

1km from the facility, and 250 meters extending out 2.5km from the facility.

To determine an appropriate and conservative background value, Ohio EPA looked at 

the 3-month average concentrations from this monitor from 2008 to 2010. The 3-month 

average concentrations for each year were averaged and the highest of the three years 

was used as a background value. This value is 0.0176 ug/m3 (see the attached monitor 

summary for the computation). 

A total potential impact considering a conservative background value using the 

background monitor above is seen in Table 10:

This value is below 50% of the NAAQS, or 0.075 ug/m3. 

Conclusion 

This letter addresses the items necessary to apply for a waiver of monitoring 

requirements for American Electric Power – James A. Gavin Facility, Severstal Warren, 

and I. Schumann. 

The reported emissions from American Electric Power – James A. Gavin Facility were 

0.8 TPY but modeling did not identify any local areas of high impact around the facility. 

Therefore, Ohio requests that U.S. EPA waive the requirement to monitor at this 

location. 
30 | Page

The reported emissions from Severstal Warren were 0.58 TPY but modeling did not 

identify any local areas of high lead impacts around the facility. Therefore, Ohio 

requests that U.S. EPA waive the requirement to monitor at this location. 

The reported emissions from I. Schumann were 0.79 TPY but modeling did not identify 

any local areas of high lead impacts around the facility. Therefore, Ohio requests that 

U.S. EPA waive the requirement to monitor at this location. 

If you have any questions regarding this request, please contact Jennifer Hunter, 

Manager, SIP Section, Division of Air Pollution Control at 614-644-3696. 

Sincerely, 

Robert Hodanbosi 

Chief, Division of Air Pollution Control
