EPA Technical Analysis for the Liberty-Clairton Area

Introduction

Pursuant to section 107(d) of the Clean Air Act, the Environmental Protection Agency (EPA) must 

designate as nonattainment those areas that violate the national ambient air quality standard (NAAQS) 

and those nearby areas that contribute to violations. This technical analysis for the Liberty-Clairton 

area identifies the counties with monitors that violate the 2006 24-hour PM2.5 standard and evaluates 

nearby counties for contributions to fine particle concentrations in the area. EPA has evaluated these 

counties based on the weight of evidence of the following nine factors recommended in EPA guidance 

and any other relevant information: 

- pollutant emissions 

- air quality data 

- population density and degree of urbanization 

- traffic and commuting patterns 

- growth 

- meteorology 

- geography and topography 

- jurisdictional boundaries 

- level of control of emissions sources 

We also used analytical tools and data such as pollution roses, fine particle composition monitoring 

data, back trajectory analyses, and the contributing emission score (CES) to evaluate these areas. (See 

additional discussion of the CES under Factor 1). 

 

Figure 1 is a map of the counties in the Liberty-Clairton area and other relevant information such as the 

locations and design values of air quality monitors, and the metropolitan area boundary.

For the Liberty-Clairton area, EPA previously established PM2.5 nonattainment boundaries for the 

1997 PM2.5 NAAQS that included a portion of Allegheny County, Pennsylvania. 

In December 2007, the Commonwealth of Pennsylvania recommended that the same portion of 

Allegheny County be designated as “nonattainment” for the 2006 24-hour PM2.5 standard based on air 

quality data from 2004-2006. These data are from Federal Reference Method (FRM) monitors located 

in the Commonwealth. (See the December 28, 2007 from the Pennsylvania Department of the 

Environment to EPA, received on January 3, 2008.) 

In August 2008, EPA notified the Commonwealth of Pennsylvania of its intended designations. In this 

letter, EPA also requested that if the Commonwealth of Pennsylvania wished to provide comments on 

EPA’s intended designation, it should do so by October 20, 2008. EPA stated that it would consider 

any additional information (e.g., on power plants or partial county areas) provided by the state in 

making final decisions on the designations. 

Based on EPA's technical analysis described below, EPA has designated that the same portion of 

Allegheny County, PA as nonattainment for the 2006 24-hour PM2.5 air-quality standard as part of the 

Liberty-Clairton nonattainment area, based upon currently available information. These counties are 

listed in the table below.

The following is a technical analysis for the Liberty-Clairton area. 

Factor 1: Emissions data 

For this factor, EPA evaluated county level emission data for the following PM2.5 components and 

precursor pollutants: PM2.5 emissions total, PM2.5 emissions carbon, PM2.5 emissions other, sulfur 

dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), and ammonia (NH3). 

“PM2.5 emissions total” represents direct emissions of PM2.5 and includes: “PM2.5 emissions carbon,” 

“PM2.5 emissions other,” primary sulfate (SO4), and primary nitrate. (Although primary sulfate and 

primary nitrate, which are emitted directly from stacks rather than forming in atmospheric reactions 

with SO2 and NOx, are part of “PM2.5 emissions total,” they are not shown in Table 1 as separate 

items). “PM2.5 emissions carbon” represents the sum of organic carbon (OC) and elemental carbon 

(EC) emissions, and “PM2.5 emissions other” represents other inorganic particles (crustal). Emissions 

of SO2 and NOx, which are precursors of the secondary PM2.5 components sulfate and nitrate, are also 

considered. VOCs and NH3 are also potential PM2.5 precursors and are included for consideration. 

Emissions data were derived from the 2005 National Emissions Inventory (NEI), version 1. See 

http://www.epa.gov/ttn/naaqs/pm/pm25_2006_techinfo.html. 

EPA also considered the Contributing Emissions Score for each county. The CES is a metric that takes 

into consideration emissions data, meteorological data, and air quality monitoring information to 
3

provide a relative ranking of counties in and near an area. Note that this metric is not the exclusive 

manner for considering data for these factors. A summary of the CES is included in Attachment 2, and 

a more detailed description can be found at 

http://www.epa.gov/ttn/naaqs/pm/pm25_2006_techinfo.html#C. 

However, no CES values were calculated for the Liberty-Clairton area due too its unique circumstance 

of being a portion of Allegheny County, completely surrounded by the Pittsburgh area. Please see the 

technical analysis for the Pittsburgh area for CES scores for that area. 

Table 1 shows emissions of PM2.5 and precursor pollutants components (given in tons per year) for 

violating and potentially contributing counties in the Liberty-Clairton area. The Liberty-Clairton 

nonattainment area for the 1997 PM2.5 NAAQS is shown in boldface.

The Liberty-Clairton area is located in the Monongahela River Valley, known as the Mon Valley. The 

Mon Valley is historically an industrial area. Emissions in the Liberty-Clairton area are dominated by 

the U.S. Steel Clairton Cokes Works. Clairton Works is located approximately 20 miles south of 

Pittsburgh in Clairton, PA, and sits along the west bank of the Monongahela River. The Clairton 

Works is the country's largest coking operation, with 816 ovens grouped into 12 batteries, and annual 

capability of 4.7 million tons. Coke is produced by burning coal at high temperatures and is used in the 

steel making process. 

Coke is made by heating coal to extremely high temperatures (1100°C) in an oxygen deficient 

atmosphere. This concentrates the carbon, and removes any impurities. The coke produced is 

subsequently used as fuel in iron and steel production because it generates very high heat without as 

much smoke. The production of the coke itself, however, produces significant amounts of emissions 

that affect ambient PM2.5 levels in this area.

Factor 2: Air quality data 

This factor considers the 24-hour PM2.5 design values in micrograms per cubic meter (μg/m3

) for air 

quality monitors in counties in the Liberty-Clairton area based on data for the 2005-2007 period. A 

monitor’s design value indicates whether that monitor attains a specified air quality standard. The 2006 

24-hour PM2.5 standard is met when the 3-year average of a monitor’s 98th percentile values is 35 

μg/m3

 or less. A design value is only valid if minimum data completeness criteria are met. 

The 24-hour PM2.5 design values for counties in the Liberty-Clairton area are shown in Table 2.

The Liberty-Clairton portion of Allegheny County shows a violation of the 2006 24-hour PM2.5

standard. Therefore, this portion of Allegheny County is included in the Liberty-Clairton 

nonattainment area. Beaver County, PA, Brooke County, WV, Hancock County, WV, Washington 

County, PA, and Westmoreland County, PA and other parts of Allegheny County outside the LibertyClairton area also show violations of the 2006 24-hour PM2.5 standard. However, Allegheny County 

(except for the Liberty-Clairton area) and Beaver, Washington, and Westmoreland Counties in 

Pennsylvania are part of the Pittsburgh nonattainment area for the 1997 and 2006 PM2.5 NAAQS and 

therefore, are not included in the Liberty-Clairton area for the 2006 24-hour PM2.5 standard. In 

addition, Brooke and Hancock Counties in West Virginia are part of the Steubenville-Weirton 

nonattainment area for the 1997 and 2006 PM2.5 NAAQS and therefore, are not included in the 

Liberty-Clairton area for the 2006 24-hour PM2.5 standard. 

There are eight air quality monitors in Allegheny County. In Figure 2, PM2.5 design values at seven of 

the eight monitors correlate well. However, the PM2.5 design value at Liberty Borough is considerably 

higher. The 2005 - 2007 design value at the Liberty Borough monitor is 60.9 μg/m3

, while the design 

values at the other seven monitors in Allegheny County are between 34 and 40 μg/m3

. The large local 

sources plus the unique topographical features in this location result in substantially higher PM2.5

monitored values at the Liberty Borough monitor than the other monitors in Allegheny County.

Figure 2. 2005-2007 Design Values in Allegheny County and Surrounding Counties 

*Monitor 421250200 in Washington County, PA has incomplete data for 2006. 

This point is demonstrated dramatically by contrasting the design value at the Liberty Borough 

monitor, 60.9 μg/m3

, with that of the Clairton monitor, 33.9 μg/m3. The Clairton monitor is two miles 

southwest of the Liberty Borough monitor, and less than a mile southwest of the Clairton Coke Works. 

Figure 2.1. Aerial View of Liberty Borough and Clairton Monitors (Google Earth 2008) 

Speciation data further illuminates Liberty-Clairton area’s unique local problem. The Allegheny 

County Health Department (ACHD) conducted an 18-month study which compared PM2.5 speciation 

data at the Liberty Borough monitor to another monitor in Allegheny County, the Lawrenceville 

monitor. (See, “PM2.5 Chemical Speciation and Related Comparisons at Lawrenceville and Liberty: 

18-Month Results,” dated June 7, 2005, prepared by Jason Maranche, Allegheny County Health 

Department, which is attached.) The Lawrenceville monitor (# 42-003-008) is located in Pittsburgh, 

downwind from the central business district. The Liberty Borough monitor site is located in the 

Monongahela Valley, which contains a mix of urban residential, heavy industrial and rural areas.

The ACHD study showed that the Lawrenceville monitor is impacted by sulfates during warmer 

weather and nitrates during colder weather. The Liberty Borough monitor showed similar levels of 

nitrates and sulfates, depending on the season. However, the main species detected year-round at 

Liberty Borough were organic and elemental carbon. 

The ACHD study included the following plot showing total concentrations at both monitors over the 

18-month period. See Figure 2.2. 

Figure 2.2 

The ACHD study made the following observations: 

• “Total PM2.5 at Lawrenceville and Liberty show similar peaks at the same times, but to varying 

extents at each site. Liberty is generally the highest site on peak days, but can be lower for some 

peaks. On average or low PM2.5 days, Liberty and Lawrenceville are often nearly equal. This 

indicates that regional flow and meteorology may be the primary controlling factors in the 

formation of PM2.5 on low and average days. Wind speed aloft (upper air), relative humidity, and 

temperature can affect both sites on a broad-scale. Additional accumulation at Liberty may be 

dependent on local conditions such as surface wind and temperature.” 

• “Major species concentrations at Lawrenceville parallel those sampled at other Eastern U.S. 

metropolitan areas, while the concentrations at Liberty follow their own course. The differences in 

concentrations of many elements may provide clues to the regional, urban excess, and localized 

river valley components of PM2.5 in Allegheny County.” 

Every 6 days, the sampling at the Liberty Borough and Lawrenceville monitors is concurrent. An 

analysis of the concurrent sampling in the ACHD study showed that sulfate and nitrate concentrations 
7

at both site were very similar. The ADCH study concluded that, sulfates and nitrates are regional 

species. However, there were large differences between the two monitors for organic and elemental 

carbon. The ACHD study showed that ammonium and “other” species are also higher at the Liberty 

Borough monitor than at Lawrenceville. However, carbon, especially organic carbon, is by far the 

dominant species at Liberty Borough. 

The ACHD study included the following plots showing organic and elemental carbon concentrations at 

both monitors over the 18-month period. See Figures 2.3 and 2.4. 

Figure 2.3 
8

Figure 2.4 

The ACHD study also looked at two other monitors in southwestern Pennsylvania, one upwind from 

Allegheny County and one downwind. The upwind monitor, the Florence monitor, is in the 

northwester corner of Washington County, PA. This monitor is west of the Lawrenceville monitor, 

and northwest of the Liberty Borough monitor. Downwind, the Greensburg monitor is located in 

Westmoreland County. This monitor is east of the Liberty Borough monitor, and southeast of the 

Lawrenceville monitor. (Please note that Washington and Westmoreland Counties are in the Pittsburgh 

nonattainment area for the 1997 PM2.5 NAAQS.) The ACHD study found that, “By total gravimetric 

(weighed) mass concentrations, Florence, Lawrenceville, and Greensburg match well, indicative of the 

regional flow through the multi-county area. Liberty Borough shows the highest mass concentrations, 

due to regional flow plus localized excess. Lawrenceville and Greensburg show the next highest 

concentrations, due to gained urban excess. Accordingly, Florence is usually the lowest by total mass, 

since it reflects regional flow without localized urban excess.” 

Furthermore, concentrations of sulfate and nitrate track well with all four monitors, indicating that they 

are regional pollutants. Organic carbon, elemental carbon, and ammonium are higher at Liberty 

Borough. As when comparing Liberty Borough to Lawrenceville alone, organic carbon at Liberty 

Borough is far higher than at the other three monitors. 

On peak PM days, organic carbon is anywhere from a few μg/m3

 higher at Liberty Borough to nearly 

20 μg/m3

 higher. Similarly, elemental carbon is from a few μg/m3 higher at Liberty Borough to about 

12 μg/m3

 higher. The differences in ammonium concentrations are much smaller, from 1 or 2 μg/m3 to 

about 7 μg/m3

. The additional concentrations of organic carbon, elemental carbon, and ammonium 

account for the more than 20 μg/m3

 difference between Liberty Borough and the other monitors in 

Southwester Pennsylvania. (See Table 2.1.)

Similarly, speciation data from the Liberty Borough monitor compared to other surrounding 

nonattainment areas shows similar results. A comparison of speciation data from the Liberty Borough 

monitor to Morgantown, WB to the south; Steubenville-Weirton, WV to the west; and Johnstown, PA 

to the east shows that carbon is far higher at Liberty Borough then the other areas. See Table 2.2.

Thus, the high concentrations of carbon at the Liberty Borough monitor indicate a unique local 

problem in the area. The additional carbon is, on average, approximately equal to the difference 
10

between the Liberty Borough design concentration and the concentration for the remainder of the 

surrounding Pittsburgh area. 

Under this factor, we also consider fine particle composition monitoring data. Air quality monitoring 

data on the composition of fine particle mass are available from the EPA Chemical Speciation 

Network and the IMPROVE monitoring network. Analysis of these data indicates that the days with 

the highest fine particle concentrations in the Liberty-Clairton area occur predominantly in the 

summer. The average chemical composition of the highest days is illustrated in Figure 2.5, below. 

This data indicates that sources of direct PM2.5 carbon and SO2 emissions are key contributors to 

exceedances in the area. This data corresponds with the data compiled and analyzed by ACHD, which 

is discussed above.

Note: Eligible monitors for providing design value data generally include State and Local Air 

Monitoring Stations (SLAMS) at population-oriented locations with an FRM monitor. All data from 

Special Purpose Monitors (SPM) using an FRM is eligible for comparison to the relevant NAAQS, 

subject to the requirements given in the October 17, 2006 Revision to Ambient Air Monitoring 

Regulations (71 FR 61236). All monitors used to provide data must meet the monitor siting and 

eligibility requirements given in 71 FR 61236 to 61328 in order to be acceptable for comparison to the 

2006 24-hr PM2.5 NAAQS for designation purposes. 

Factor 3: Population density and degree of urbanization (including commercial development) 

Table 3 shows the 2005 population for each county in the area being evaluated, as well as the 

population density for each county in that area. Population data gives an indication of whether it is 

likely that population-based emissions might contribute to violations of the 2006 24-hour PM2.5

standard. The Liberty-Clairton area for the 1997 PM2.5 NAAQS area is shown in boldface.

Because of the unique nature of the Liberty-Clairton area, with its local source and topography issues, 

this factor does not weigh heavily in this technical analysis. The Liberty-Clairton area is completely 

surrounded by the Pittsburgh area. This factor is fully considered in the technical analysis for the 

Pittsburgh area. 

Factor 4: Traffic and commuting patterns

This factor considers the number of commuters in each county who drive to another county within the 

Liberty-Clairton area, the percent of total commuters in each county who commute to other counties 

within the Liberty-Clairton area, as well as the total Vehicle Miles Traveled (VMT) for each county in 

millions of miles (see Table 4). A county with numerous commuters is generally an integral part of an 

urban area and is likely contributing to fine particle concentrations in the area.

The listing of counties on Table 4 reflects the number of people commuting to other counties. The 

Liberty-Clairton area for the 1997 PM2.5 NAAQS area is shown in boldface. 

Because of the unique nature of the Liberty-Clairton area, with its local source and topography issues, 

this factor does not weigh heavily in this technical analysis. The Liberty-Clairton area is completely 
12

surrounded by the Pittsburgh area. This factor is fully considered in the this technical analysis for the 

Pittsburgh area. 

Factor 5: Growth rates and patterns 

This factor considers population growth for 2000-2005 and growth in VMT for 1996-2005 for counties 

in Liberty-Clairton area, as well as patterns of population and VMT growth. A county with rapid 

population or VMT growth is generally an integral part of an urban area and likely to be contributing 

to fine particle concentrations in the area. 

Table 5 shows population, population growth, VMT, and VMT growth for counties that are included in 

the Liberty-Clairton area. The Liberty-Clairton area for the 1997 PM2.5 NAAQS area is shown in 

boldface.

Because of the unique nature of the Liberty-Clairton area, with its local source and topography issues, 

this factor does not weigh heavily in this technical analysis. The Liberty-Clairton area is completely 

surrounded by the Pittsburgh nonattainment area. This factor is fully considered in the technical 

analysis for the Pittsburgh area. 

Factor 6: Meteorology (weather/transport patterns) 

For this factor, EPA considered data from National Weather Service instruments and other 

meteorological monitoring sites in the area. Wind direction and wind speed data for 2005-2007 were 

analyzed, with an emphasis on “high PM2.5 days” for each of two seasons (an October-April “cold” 

season and a May-September “warm” season). These high days are defined as days where any FRM 

air quality monitors had 24-hour PM2.5 concentrations above 95% on a frequency distribution curve of 

PM2.5 24-hour values. 

For each air quality monitoring site, EPA developed a “pollution rose” to understand the prevailing 

wind direction and wind speed on the days with highest fine particle concentrations. Figures 6 and 6.2 

identify 24-hour PM2.5 values by color; days exceeding 35 ug/m3 are denoted with a red or black icon. 

A dot indicates the day occurred in the warm season; a triangle indicates the day occurred in the cool 

season. The center of the figure indicates the location of the air quality monitoring site, and the 

location of the icon in relation to the center indicates the direction from which the wind was blowing 

on that day. An icon that is close to the center indicates a low average wind speed on that day. Higher 

wind speeds are indicated when the icon is further away from the center. 
13

The pollution roses for the Liberty-Clairton area (Figures 6 and 6.2) show that winds in the area are 

predominantly from the southwest. At the Liberty Borough monitor (# 420033064), high PM2.5 days 

(days with PM2.5 greater than 35 μg/m3

) are primarily days with winds from southwest and south, 

which is direction of the Clairton Coke Works. (See Figures 6 and 6.1.) To a far lesser degree, some 

days with high ambient PM2.5 have winds from the northwest.

The ACHD study referenced in Factor 2 (“PM2.5 Chemical Speciation and Related Comparisons at 

Lawrenceville and Liberty: 18-Month Results,” dated June 7, 2005) also considered meteorology. 

That study stated that the Liberty Borough monitor, located in the Mon Valley, was much more 

affected by inversions than the Lawrenceville monitor, located to the northwest of Liberty Borough in 

Pittsburgh. The ACHD study concluded that, “Liberty PM2.5 levels are highly influenced by nocturnal 

temperature inversions, when warmer upper-air layers trap pollutants close to surface level. 

Lawrenceville is moderately influenced by inversions near daybreak, but overall the levels remain 

steadier at Lawrenceville on a diurnal basis.” 

Note: The meteorology factor is also considered in each county’s Contributing Emissions Score 

because the method for deriving this metric included an analysis of trajectories of air masses for high 

PM2.5 days. 

Factor 7: Geography/topography (mountain ranges or other air basin boundaries) 

The geography/topography analysis looks at physical features of the land that might have an effect on 

the air shed and, therefore, on the distribution of PM2.5 over the Liberty-Clairton area. 

The Clairton Coke Works is at the base of the Mon Valley, approximately 750 feet above mean sea 

level (MSL). (See Figures 7 and 7.1, topographic maps of the area.) The facility sits on the west bank 

of the Monongahela River. On the east bank, the terrain rises sharply reaching elevations more than 

300 feet above the coke works within a thousand feet of the plant. (See Figure 7.2, a three dimensional 

view to the north from the Clairton Coke Works.) The Liberty Borough monitor is about 1100 feet 

above MSL, to the northeast of the coke works. (See Figure 7.3, which is an aerial view of the 

Liberty-Clairton area.)

As stated in Pennsylvania’s December 28, 2007 designation recommendation letter regarding the 

Pittsburgh area: “This region of Pennsylvania is dominated by relatively high terrain cut by numerous 

river valleys. While these features tend to trap local emissions . . .” This tendency to trap local 

emissions, combined with large local emissions, would explain why the monitored values at the 

Liberty Borough monitor are so much higher than at the other monitors in the Pittsburgh area. 

Furthermore, in its October 20, 2008 letter to EPA regarding boundary recommendations for the 2006 

PM2.5 NAAQS, the Pennsylvania Department of Environmental Protection (PADEP) stated that the 

Clairton Coke Works facility has stack heights that are lower than normal power plant stacks. This 

would mean that the effects of a source like the coke works would impact the ground at a much closer 

location locally than a power plant. PADEP’s October 20, 2008 letter also explained that the highest 

fine particulate concentrations occur at the Liberty Borough monitor when there are southsouthwesterly winds along with a morning inversion. A morning inversion occurs when the ground is 

cooler than the air above it; normally at night, the area is under the control of high pressure and clear 

skies. With the warmer air being above the cooler air, vertical mixing is at a minimum. Therefore, 

anything exhausted in the boundary layer with an inversion in place will remain trapped in that layer. 

For example, as the coke works’ low level sources emit emissions, the plume of emissions will only 

rise to the top of the inversion layer. At that point, the pollution is spread out horizontally. These 
17

inversions usually set up only a few hundred feet above the surface. Therefore, fine particulate levels 

can become very high near the surface. In this case, the plume impacts the hillside across the river as 

well; the plume is actually not traveling large distances. This is evident from the speciation data from 

two sites, Liberty and Lawrenceville. (For more information on speciation data, see Factor 2, above.) 

Factor 8: Jurisdictional boundaries (e.g., existing PM2.5 areas) 

In evaluating the jurisdictional boundary factor, EPA gave special consideration to areas that were 

already designated nonattainment in 2005 for violating the 1997 fine particle standards. Analysis of 

chemical composition data in these areas indicates that the same components that make up most of the 

PM2.5 mass in the area on an annual average basis (such as sulfate and direct PM2.5 carbon in many 

eastern areas) also are key contributors to the PM2.5 mass on days exceeding the 2006 24-hour PM2.5

standard. These data indicate that in many cities, the same source categories that contribute to 

violations of the annual standard also contribute to exceedances of the 2006 24-hour standard. 

Most areas that were originally designated nonattainment for the PM2.5 standards still have not attained 

the standards. Thus, EPA has generally concluded that counties that were designated as having 

emissions sources contributing to fine particle concentrations which continue to exceed the 1997 

standards (all areas violated the annual standard, three also violated the previous 24-hour standard) 

also contribute to fine particle concentrations on the highest days. For this reason, EPA believes that 

for most existing nonattainment areas, the nonattainment area for the 2006 24-hour standard should be 

the same. Consideration also should be given to existing boundaries and organizations as they may 

facilitate air quality planning and the implementation of control measures to attain the standard. Areas 

already designated as nonattainment represent important boundaries for state air quality planning. 

There are no jurisdiction issues in the Liberty-Clairton area. The five municipalities in the current 

PM2.5 nonattainment area are all within Allegheny County, PA. The PM2.5 planning for the area is 

under the purview of the Allegheny County Health Department. The Pennsylvania Department of 

Environmental Protection does the planning for the Pittsburgh nonattainment area. However, these 

two agencies have a long history of cooperation. EPA believes that while the control measures put in 

place by PADEP for the Pittsburgh area may help the Liberty-Clairton area move closer to attainment, 

ACHD may be required to implement some local measures. 

Factor 9: Level of control of emission sources 

Under this factor, the existing level of control of emission sources is taken into consideration. The 

emissions data used by EPA in this technical analysis and provided in Table 1 (under Factor 1) 

represent emissions levels taking into account any control strategies implemented in the LibertyClairton area before 2005 on stationary, mobile, and area sources. Data are presented for PM2.5

components that are directly emitted (carbonaceous PM2.5 and crustal PM2.5) and for pollutants which 

react in the atmosphere to form fine particles (e.g. SO2, NOx, VOC, and ammonia). 

In considering county-level emissions, EPA used data from the 2005 National Emissions Inventory, 

the most updated version of the national inventory available at the beginning of the designations 

process in late 2007. However, EPA recognized that for certain counties, emissions may have changed 

since 2005. For example, certain power plants or large sources of emissions in or near this area may 

have installed emission controls or otherwise significantly reduced emissions since 2005. Some States 

provided updated information on emissions and emission controls in their comments to EPA. EPA 

considered such additional information in making final designation decisions. 
18

With regard to nearby power plants, EPA considered information about whether a specific plant 

installed federally enforceable emission controls by December 2008 resulting in significant emissions 

reductions. A control requirement is considered to be federally-enforceable if it is required by a State 

regulation adopted in a State implementation plan, if it is included in a federally-enforceable Title V 

operating permit, or if it is required by a consent decree which also requires the controls to be included 

in federally enforceable permit upon termination of the consent decree. In making final decisions, 

EPA also considered whether a facility would continue to emit pollutants which contribute to PM2.5

exceedances even after emission controls are operational. 

As explained above in Factor 1, emissions in the Liberty-Clairton area are dominated by the U.S. Steel 

Clairton Cokes Works. In June 2007, U.S. Steel signed a consent agreement with the Allegheny 

County Health Department that requires the company to make repairs costing approximately $76 

million at its Clairton Coke Works. Under this agreement CD, U.S. Steel must reduce emissions at its 

Clairton Coke Works according to a strict schedule. U.S. Steel is required to replace the walls in the 

ovens by June 30, 2010. The company could also be fined by the hour for visible pollution emissions 

detected by a smoke monitor, and must pay a $50,000 fine if that monitor is not working 90 percent of 

the time during each calendar quarter. However, EPA only considered controls in place and federally 

enforceable at the time of designation. Therefore, these planned future controls were not considered in 

this analysis. However, these future reductions will be relevant for the nonattainment area plan 

developed for this area. 

Conclusion 

The detailed technical analysis, including referenced data, set forth in Factors 1, 2, 6, 7 and 9, supports 

a finding that this area presents local air quality problems that differentiate this area from the 

surrounding area. Because of a very localized source of emissions and the unique topography which 

contains the emissions in this area, EPA has determined that it is appropriate to establish LibertyClairton as a separate nonattainment area within the larger Pittsburgh-Beaver Valley nonattainment 

area for the 2006 PM2.5 NAAQS. 

The Clairton Coke Works is a large and complex facility that emits a combination of particulates, 

sulfur dioxide, ammonia, and hundreds of volatile organic chemicals. Although the coke plant has 

numerous existing emission controls, the combination of a large amount of low-level emissions in a 

narrow river valley creates a local air quality problem which is uniquely different from the remainder 

of the area. 

To illustrate the exceptional situation in the Liberty-Clairton area, one need only look at data from the 

eight air quality monitors in Allegheny County. PM2.5 monitored values in seven of the eight monitors 

correlate well. Design values for 2005 - 2007 at seven monitors in Allegheny County are between 34 

and 40 μg/m3

. However, the 2005-2007 design value at the Liberty Borough monitor is 60.9 μg/m3. 

Concentrations of carbon at the Liberty Borough monitor far exceed those at other monitors in the 

Pittsburgh area. The additional carbon is, on average, approximately equal to the difference between 

the Liberty Borough design concentration and the concentration for the remainder of the surrounding 

Pittsburgh area. The carbon emissions from the Clairton Coke Works, trapped in the area because of 

its unique topographical situation, account for the excess carbon at the Liberty Borough monitor. 

For the designations for the 1997 PM2.5 NAAQS, PADEP provided extensive documentation to 

support a recommendation that a separate nonattainment area be designated within the Pittsburgh-
19

Beaver Valley nonattainment area. The recommended Liberty-Clairton area was specified as the five 

municipalities in the vicinity of the Clairton Coke Works as the “Clairton & 4 Boroughs area.” This 

area is comprised of the City of Clairton and the Boroughs of Glassport, Liberty, Lincoln and Port 

View. PADEP resubmitted this material in its October 20, 2008 letter to EPA regarding boundary 

recommendations for the 2006 PM2.5 NAAQS. EPA has concluded that the same boundaries are 

appropriate for the 2006 PM2.5 NAAQS, based upon an evaluation of the data relevant to this area and 

exceedances of these standards as well.

Summary of Air Emission Estimations from Point Sources 

 in Allegheny County 

Years 1996-2004 for Criteria Air Pollutants 

and 1998-2004 for Hazardous Air Pollutants 

Executive Summary

Although point source air emissions in Allegheny County have declined significantly since 1996 

only relatively small decreases were observed between 2003 and 2004. 

Since 1996 emissions of carbon monoxide have declined nearly 20%, nitrogen oxides 42%, PM10 

40% and volatile organic compounds 46%. Sulfur dioxide (SO2) emissions have only declined 

1%. In any year well over eighty percent of sulfur dioxide emissions from Allegheny County’s 

point sources are generated by the Reliant Cheswick Power Station located on the Allegheny 

River in Springdale, PA. SO2 emissions vary with the demand for electrical power from this plant. 

In 2004 demand was down and the facility emitted 10% less sulfur dioxide than in 2003. 

Between 1998 and 2001 emissions from the US EPA list of 188 Hazardous Air Pollutants 

(HAPs) increased 23%. In 2002 they decreased 16% and then increased again in 2003 by 12 %. 

In 2004 overall HAP emissions declined by 3%. 

Total point source HAP emissions have failed to exhibit any discernable trend between 1998 and 

2004 in Allegheny County. Cheswick Power Station, a coal burning electrical generating unit, 

emitted 82% of the total hydrochloric acid and 88% of the total hydrofluoric acid emitted by point 

sources in 2004. These two acid gasses have and continue to account for an average of 62% of all 

HAP emissions reported by point sources. 

Emissions of the five criteria pollutants from point sources in the County have trended down 

since 1996. Emissions from the Cheswick Station mask the overall degree of reduction 

attributable to the other point sources included in the annual survey. 

Examination of emission trends of both HAPS and criteria pollutants after excluding Cheswick’s 

contribution show overall declines in both categories. Emissions of HAPS have declined 25% 

since 1998.Emissions of nitrogen oxides; PM10, sulfur dioxide and volatile organic compounds 

have fallen by 50%, 42% 45% and 46% respectively. Unfortunately carbon monoxide emissions 

have only fallen by 14% in this period. These changes are largely attributable to closure or 

reduction in operations of industrial facilities in the County. 

Emissions of both HAPS and criteria pollutants from the Cheswick Power Station are 

proportional to fuel use. So the total amount of industrial air pollution in the County will be 

highly dependent on the output from this one facility. However Cheswick has acted to reduce the 

amount of pollution generated by its operation. In 2003 nitrogen oxide emissions were reduced by 

the installation of a Selective Catalytic Reduction (SCR) device.

Introduction 

The annual Air Quality Program’s Point Source Emission Inventory Report for 2004 details and 

analyzes emission estimates from facilities with potential emissions in the categories listed below: 

• 25 TPY or more of any criteria pollutant 

• 10 TPY or more of any single Hazardous Air Pollutant (HAP) 

• 25 TPY or more of any mixture of HAPs 

In 1997 reporting of annual emission inventories was converted from a paper system to an 

electronic system. In 2004, 81% of submittals were made to the Allegheny County Health 

Department Website. Nineteen percent of submittals were made by e-mail. 

In 1998 the availability of emission factors for HAPS increased making possible better estimates 

of emissions for these compounds. 

This report provides graphs and tables comparing air emissions for 2004 to those from previous 

years. It contains six sections with three attachments. 

• Section I – Point source Criteria Emission Trends 

• Section II – Point Source Criteria emissions by Industry Sector 

• Section III- Sources and Form of Particulate Emissions- PM10, PM2.5, 

filterable and condensable. 

• Section IV – Point source HAP Emissions 

• Section V – Point Source HAP Emission Trends 

• Section VI – Impact of the Reliant Cheswick Power Station on Total County 

Point Source Emissions 

Cheswick Power Station’s emissions merit a separate section because their total emissions are far 

greater than those of any other facility in the County. 

• Attachment A – Criteria Pollutant Emissions for Individual Facilities 

• Attachment B – List of HAP Emissions by Compound.

The pollutants shown include: 

• CO – carbon monoxide 

• NOx – emissions of oxides of nitrogen reported as nitrogen dioxide 

• PM2.5 – filterable particulate with an aerodynamic diameter less than 2.5 

microns 

• PM10 - filterable particulate with an aerodynamic diameter less than 10 

microns 

• PT- total filterable particulate 

• PMCOND- condensable particulate matter defined as material in the vapor 

state at temperatures above 68o F. and a solid at lower temperatures. 

• SO2- sulfur dioxide 

• VOCs – Volatile Organic Compounds. 

More detailed definitions are provided in the notes located at the end of the report. 

Emissions of all criteria pollutants from the point sources in Allegheny County declined in 2004 

with the exception of condensable particulate. It increased by 1.6%.

Trends in emissions of criteria pollutants in the County are discussed by industry sector in 

Section II. Section VI addresses contributions from the Cheswick Power Station to total County 

point source emissions. 

Section II Criteria Point Source Air Emissions by Industrial Sector

Graphs 2a-2e detail emissions of each criteria pollutant from individual point source industrial 

sectors in the County. The six industrial sectors identified account for approximately 94% of all 

criteria point source air emissions. Facilities are sorted into sectors based on the size of their 

contribution to total air emissions. With the exception of sulfur dioxide, emissions of criteria 

pollutants have continued to decline overall. In 2004 a small increase in the condensable 

particulate was observed. Contributions from individual sectors show declines from the 1996 base 

despite some increases attributable to variable business conditions.

Sulfur dioxide emissions do not show a clear trend over the period examined. 

Approximately 90% of all sulfur dioxide emissions in the County in 2004 are from the 

Cheswick Power Station. Therefore, emissions of this compound from this source are 

addressed in Section VI. Emissions from this source overwhelm SO2 emissions from

other point sources in the County and determine the overall direction of SO2 emissions. 

Fifty percent of the decrease in sulfur dioxide emissions from integrated carbon steel 

production since 1998 is attributable to the closing of the Hazelwood LTV Coke Works.

Prior to 2004 significant decreases in emissions of nitrogen oxides were observed. 

However, the rate of decrease in the emissions of this pollutant in the last two years has 

leveled off. Between 2002 and 2003 emissions of nitrogen oxides decreased 11%. 

Between 2003 and 2004 the decrease of emissions of this pollutant was only 3%. 

The small decrease in nitrogen dioxide emissions in 2004 is due to small decreases in the 

integrated carbon steel production sector partially offset by a small increase in the utility

category.

Unlike the period from 1996 to 2002, no large source of nitrogen oxide emissions has 

shut down recently. The large decreases in emissions of nitrogen oxides between 1996 

and 2003 were largely attributable to the shutdown of the LTV Coke Works in 1998 and 

the Kosmos Cement kiln in 2001 and the installation of selective catalytic reduction 

control equipment at the Cheswick Power Station in 2003.

VOC emissions in 2004 increased 4.6% over 2003. Roughly three-quarters of this 

increase came from the integrated carbon steel sector. Otherwise as Graph 2c illustrates 

emissions of this pollutant have fluctuated within a narrow range since 2002.

Emissions of carbon monoxide continued to decline in 2004 decreasing 6% from the 

level reported in 2003. All industrial sectors exhibited a decline in emissions of this 

pollutant except for the sources included in the other industrial category where there was 

an increase of 6%. 

Section III Particulate Emissions and Their Sources

In the Allegheny County Emission Inventory, four forms of particulate matter are reported. These 

are total particulate (PT), condensable particulate (PMCond), PM10 and PM2.5. The last two are 

fractions of total particulate. Below are the definitions of each of these forms 

Page 9 of 121

 

 

 
• PT- total filterable particulate is the material captured from flue gas on a 

filter heated to 248oF. 

• PM10 - fraction of filterable particulate with an aerodynamic diameter less 

than 10 microns 

• PM2.5 – fraction of filterable particulate with aerodynamic diameter less than 

2.5 microns. 

• PMCond- material collected from the filtered flue gas after it has passed 

through the 248oF filter as a gas and been condensed from the sample stream

and dried. 

PM2.5, PM10 and PT are not independent of each other. PM2.5 is a fraction of both PM10 

and PT. PM10 is a fraction of PT. Condensable particulate is not part of filterable particulate and 

its fractions in flue gas. It is a gas that condenses in ambient air to fine particulates. 

Graph 3 is an illustration of the amount of each form of particulate matter released by each 

industrial sector through 2004

Section IV Hazardous Air Pollutants (HAPS)

Facilities are required to report emissions of any of the 188 HAPs listed in ACHD Article XXI, 

Section 2101.20.a. Article XXI is consistent with EPA Section 112(b) of the Clean Air Act. 

Both hydrogen sulfide and ammonia are reported in this category. Hydrogen sulfide is a 

contaminant listed in Article XXI. Ammonia must be reported because it is a particulate precursor 

in air. Some HAPs are speciated when reported. Speciation is applied to exceptionally toxic 

HAPS such as hexavalent chromium. 

HAP reporting requirements became more stringent with the 1999 Emission Inventory. 

Speciation for some compounds was introduced. So HAP emission estimates prior to 1999 are not 

comparable to those of previous years. 

Attachment B lists point source HAP emissions in Allegheny County by total amount of 

individual compound. Adjustments to emissions of hydrochloric acid (HCl) and hydrofluoric acid 

(HF) are explained following the table. 

The impact of exposure to individual HAP compounds varies greatly with both the concentration 

and the chemical properties of the compound. Exposure concentrations required to observe 

negative health impacts can differ by several orders of magnitude among different compounds. 

Synergistic effects of exposure to combinations of HAPs at differing concentrations have not 

been thoroughly studied.

HF and HCl constitute 62% of total HAP emissions from County sources for the period 1998-

2004. In 2003 and 2004 emissions of these two compounds from the Cheswick Power Station 

accounted for 40 % of total HAP emissions reported by point sources. The three largest sources 

of HCl and HF emissions are the Cheswick Power Station, the USS Clairton Works and the USS 

Irvin Plant. Emissions of HCl from Cheswick in any given year are between 30 to 40 times the 

amount emitted from the USS Clairton Works, the second largest emitter of this compound. In 

2004 Cheswick accounted for 82% of total HCl emissions. Emissions of HF From Cheswick are 

approximately 85% of total emissions of this compound from point sources in the County.

Emissions of HF and HCl rise and fall depending on the demand for electricity from the 

Cheswick Power Station and are therefore roughly proportional to the amount of coal burned. 

However, when emissions of these two HAPs are excluded from the total, Graph 4 shows 

emissions of HAP compounds from other sources have steadily declined-- falling 25% since 

1998. 

Page 12 of 121

 

 

 
Section VI. Comparison Emissions of the Cheswick Power Station to Total County Point Source 

Emissions. 

The Cheswick Power Station is the single largest point source emitter of both criteria pollutants 

and HAPs in Allegheny County. Graph 5 shows its contributions to total CO, PM10, and VOCs is 

relatively small. But in 2004 it accounted for 35% of nitrogen oxide point source emissions and 

89% of those of sulfur dioxide.

Operations at Cheswick fluctuate with the demand for electricity, which is dependent on many

economic factors. Demand for power from this plant disproportionately determines the total level 

of pollution in the County. The size of its contribution to total pollution masks emission trends 

from other point sources which overall are declining or fairly constant. See Graph 6. 

Page 14 of 121

 

 

 
Graph 7 examines trends of emissions of criteria pollutants from the Cheswick Power Station as a 

function of production since 1990. Since the sulfur content of the coal burned was relatively

constant, sulfur dioxide emissions per unit of energy consumed were fairly stable.

The installation of particulate and nitrogen oxide control equipment has contributed to the overall 

decline of emissions of these two pollutants since 1990. However, the installation of a Selective 

Catalytic Reduction System (SCR) in 2003 while reducing NOx emissions increased particulate 

emissions. In 2004 NOx emissions increased slightly while particulate emissions again declined. 

This suggests the SCR was not as available in 2004 as it was in 2003.

Notes to the report: 

1. Estimation of PM2.5 and condensable particulate (PMCOND) emissions started with the 1999 

inventory year. 

2. Hydrogen sulfide is considered a pollutant in Allegheny County. Ammonia is a particulate 

precursor. Both are listed in the HAP tables. They are not among the 188 compounds 

designated HAPs by USEPA. Speciated compounds of very toxic HAPs such as hexavalent 

chromium and dioxin isomers are not specifically listed in ACHD Article XXI as HAPS, but 

are reported at de-minimus emission levels in the inventory. 

3. Lead emissions are included in the HAPs tables. 

4. Definitions of Emissions 

4.1. Filterable Particulate – Material emitted as liquid or solid at 248o

F 

4.2. Condensable Particulate (PMCOND) – Material that is not filterable at 248o

F and 

 condenses when passed through water in an ice bath. 

4.3. Total Particulate (PT) – Filterable Particulate 

4.4. PM10 - Filterable particulate with aerodynamic diameter less than 10 microns. 

4.5. PM2.5 - Filterable particulate with aerodynamic diameter less than 2.5 microns 

4.6. Volatile Organic Compounds (VOCs) – Organic material that is photo reactive and a 

 gas at 250o

F. Contributes to the formation of ozone. 

5. The sheet "HAPs" lists yearly emissions of HAPs for each source from 1998 - 2004. HAP 

emissions were estimated prior to this, but results are believed to be less accurate. 

6. The DLM facility, formerly Heinz, is in the category Industrial Coal Fired Boiler. 

7. Emission estimates for each facility are calculated each year. Estimates of previous years are 

not normally updated if emission factors or estimation techniques change for processes.

Previous emission inventory assessments are not normally recalculated when estimation are 

improved techniques or emission factors updated. Therefore, emissions may appear to increase 

or decrease, but such changes are not real. An exception has been made for the acid gases HCl 

and HF, and adjustments have been made to previous years’ inventories. 

Examples are the estimates of emissions of the two acid gasses from the Cheswick Power Station. 

Changes in the emission factors used for HCl and HF during 2002 produced estimates different 

enough to significantly affect the reported HAP emissions from this plant, total emissions of these 

pollutants and the total HAP emission inventory. 

During 2000, source testing was performed for HCl emissions from coke oven stacks at the USS 

Clairton Coke Plant. This testing found HCl emissions not previously known. These emissions 

were included in the 2000 and later inventories. 

Adjustments were made to previously reported Total Point Source HAP Emissions to account for 

these changes. Adjusted values are used for this comparison only. Agency emission inventory 

records have not been adjusted. 

Emissions of hydrochloric acid (HCl) are about 40% of the total emissions in Attachment B. 

Emissions of ammonia (NH3) contribute an additional 25%.

May 2005 Page 1 

1. Introduction 

Allegheny County has operated two particulate 

matter – 2.5microns or less (PM2.5) – chemical 

speciation monitors as part of EPA's STN network 

since 2001. Lawrenceville and Hazelwood were 

the initial sites of deployment, and species 

concentrations from these sites were nearly 

equal. The Hazelwood monitor was then moved 

to Liberty Borough in October 2003 to better 

ascertain PM2.5 in Liberty-Clairton area. 

Allegheny County was designated nonattainment for PM2.5 as part of the 

Pittsburgh-Beaver Valley area in December 2004. At the same time, the Liberty 

Borough-Clairton area was designated a separate nonattainment area within 

Allegheny County. 

Major species concentrations at Lawrenceville parallel those sampled at other 

Eastern U.S. metropolitan areas, while the concentrations at Liberty follow their 

own course. The differences in concentrations of many elements may provide 

clues to the regional, urban excess, and localized river valley components of 

PM2.5 in Allegheny County. 

This report shows species and pollutant comparisons between the two sites over 

the timeframe of October 2003-March 2005. All figures and tables represent 18-

month data unless otherwise noted.

2. Sites 

The Lawrenceville monitor site is an urban residential site, downwind from the 

Pittsburgh Central Business District (Downtown). Elevation is 918 feet above 

mean sea level (MSL), about 200 feet above river level. 

The Liberty Borough monitor site is located in the Monongahela Valley, which 

contains a mix of urban residential, heavy industrial, and rural areas. The 

elevation is 1100 feet MSL, and the predominant winds are southwesterly. 

Average temperature and pressure are lower at Liberty, coinciding with higher 

elevation. Elevation alone does not appear to play a role in PM2.5 concentrations 

at Liberty, as other sites such as South Fayette measure lower concentrations at 

higher elevations than Liberty. 

The speciation sampling frequency is higher at Lawrenceville (1-in-3) than at 

Liberty (1-in-6), so averages at Lawrenceville represent a larger array of values. 

For some figures in this report, dates have been matched to compare concurrent 

sampling days only. 

Both sites are collocated with other monitors, including daily PM2.5 filter-based 

(FRM) and hourly continuous PM2.5 monitors. Additionally, Lawrenceville 

measures ozone and NOx, and Liberty measures PM10, SO2, H2S, and benzene. 

Sites near Liberty include Glassport (PM10, SO2) and Lincoln (PM10). These 

nearby sites have been included in this analysis for possible correlation to 

Liberty.

3. Major Species 

Below are time series plots for Lawrenceville and Liberty PM2.5 major species 

over the 18-month timeframe. 

Lawrenceville is dominated by sulfates during summer months. In colder 

months, nitrates and organics tend to dominate. 

In late January and early February 2005, an anomaly is evident by the 

exaggerated organic carbon and nitrate peaks. This is likely due to an 

exceptional high-pressure meteorological system that led to high PM2.5

throughout the Midwest and Northeast U.S. 

Liberty shows a much different pattern of major PM2.5 species over time. While it 

shows similar levels of sulfates and nitrates to Lawrenceville, it is dominated by 

organic and elemental carbon year-round. 
 18-Month Speciation 

May 2005 Page 4 

The differences in average carbon levels, as well as ammonium and the “other” 

component, are shown below. 
 18-Month Speciation 

May 2005 Page 5 

Sulfates, nitrates, and crustal component are slightly lower at Liberty than at 

Lawrenceville. 

Crustal component is a weighted average of the aluminum, silicon, calcium, iron, 

and titanium concentrations, representative of fine soil. 

By calculating the differences of the average major species, localized excess at 

Liberty is given by the pie chart below. This excess represents the difference 

between the Lawrenceville and Liberty sites for species that are greater at 

Liberty. 

The “other” component is defined as the difference between the gravimetric 

(weighed) mass concentration and the sum of the major species. It can include 

the following: 

• Non-crustal, non-sulfur trace elements 

• Water 

• Non-organic, non-elemental carbon 

• Unknown species 
 18-Month Speciation 

May 2005 Page 6 

4. Matched Time Series, by Species 

Concurrent sampling at Lawrenceville (LV) and Liberty (LB) occurs every 6 days. 

Plots of these date-matched samples reveal direct comparisons of species at the 

two sites. Plots for major species are given below. 

Total PM2.5 at Lawrenceville and Liberty show similar peaks at the same times, 

but to varying extents at each site. Liberty is generally the highest site on peak 

days, but can be lower for some peaks. On average or low PM2.5 days, Liberty 

and Lawrenceville are often nearly equal. This indicates that regional flow and 

meteorology may be the primary controlling factors in the formation of PM2.5 on 

low and average days. Wind speed aloft (upper air), relative humidity, and 

temperature can affect both sites on a broad-scale. Additional accumulation at 

Liberty may be dependent on local conditions such as surface wind and 

temperature.
 18-Month Speciation 

May 2005 Page 7 

 

Sulfate is nearly identical at both sites year-round. This indicates that sulfate is 

primarily affected by regional flow upwind of Allegheny County. Minor 

differences in peaks may be indicative of local meteorology or minor source 

impacts. 
 18-Month Speciation 

May 2005 Page 8 

Organic carbon is similar to total mass concentration in that the peaks occur at 

the same times at both sites but to varying degrees. The peak discrepancies are 

higher for organic carbon than for total concentration, however, indicating that 

localized factors may be more controlling for organic carbon. 

Similar to organic carbon, elemental carbon shows a localized influence at 

Liberty. 
 18-Month Speciation 

May 2005 Page 9 

Ammonium can be higher at Liberty on certain days, but not as frequently as 

organic and elemental carbon. 
 18-Month Speciation 

May 2005 Page 10 

Nitrate appears to be a regional species like sulfate, although nitrate differences 

between Lawrenceville and Liberty can be more pronounced than sulfate 

differences. 

 

The crustal component appears to be a regional-only species. Liberty crustal 

component is actually lower for many days, suggesting rural behavior for some 

crustal elements at Liberty. 
 18-Month Speciation 

May 2005 Page 11 

 

The “other” component shows similar trends to organic carbon, with Liberty 

showing much greater concentrations than Lawrenceville on peak days.
 18-Month Speciation 

May 2005 Page 12 

5. Matched Time Series, Southwest PA Sites, by Species 

On a regional level, the Pennsylvania Dept. of Environmental Protection (PA 

DEP) operates two additional PM2.5 speciation monitors in Southwest PA: 

Florence and Greensburg. 

Florence (FL) is upwind from Allegheny County, located in Hillman State Park in 

Washington County, about halfway between Weirton, WV and the Pittsburgh 

International Airport. It presumably monitors regional flow of particulates into the 

Southwest PA region from upwind sources primarily in the Ohio Valley and WV 

Northern Panhandle. 

Greensburg (GB) is downwind from Allegheny County, situated east of 

Greensburg near the Westmoreland Mall. It presumably monitors outgoing 

regional flow from Southwest PA, in addition to some urban excess from 

Pittsburgh and/or Greensburg. 

For the following plots, matched time series plots for major species are first given 

for all four sites in Southwest PA, and then without Liberty. Data is shown over 

the timeframe of Oct. 2003 – Dec. 2004. 
 18-Month Speciation 

May 2005 Page 13 

By total gravimetric (weighed) mass concentration, Florence, Lawrenceville, and 

Greensburg match well, indicative of the regional flow through the multi-county 

area. Liberty shows the highest mass concentrations, due to the regional flow 

plus localized excess. Lawrenceville and Greensburg show the next highest 

concentrations, due to gained urban excess. Accordingly, Florence is usually the 

lowest by total mass, since it reflects regional flow without localized urban 

excess. 
 18-Month Speciation 

May 2005 Page 14 

 

Sulfate time series plots strongly suggest that it is the result of regional flow for 

Southwest PA, as it is nearly equal at all sites. 
 18-Month Speciation 

May 2005 Page 15 

Organic carbon shows similar patterns to total mass in Southwest PA. Liberty is 

highest overall, with Lawrenceville and Greensburg showing urban influence.
 18-Month Speciation 

May 2005 Page 16 

Elemental carbon is similar to organic carbon for Southwest PA. Higher 

concentrations at Lawrenceville for elemental carbon may be due to mobile 

source emissions.
 18-Month Speciation 

May 2005 Page 17 

 

 

Ammonium is part of the localized excess at Liberty, although to a lesser extent 

than organic and elemental carbon. Excluding Liberty, ammonium appears to be 

both regional and urban, as it is highest at Lawrenceville.
 18-Month Speciation 

May 2005 Page 18 

 

 

Nitrate appears to be regional, like sulfates, but with increased concentrations at 

Liberty and Lawrenceville. So, urban sources may have an influence on nitrate 

levels.
 18-Month Speciation 

May 2005 Page 19 

Below are averages for the southwest PA sites by major species, given in column 

clusters. Left-to-right in the column clusters is analogous to west-to-east 

geographically. 

Florence can be considered the most rural of the sites, as average 

concentrations are lowest there for all species. A noticeable increase can be 

seen for all species from Florence to Lawrenceville, and a large increase is seen 

from Lawrenceville to Liberty for the localized Liberty-excess species. 

Greensburg is lower than the two Allegheny County sites but higher than 

Florence for all species, so it is appears to be impacted by urban excess to a 

limited extent.
 18-Month Speciation 

May 2005 Page 20 

6. Trace Elements 

In addition to major species, 48 trace elements are analyzed from the speciation 

sites. Below are time series plots for Lawrenceville and Liberty trace elements. 

Sulfur, which is always much higher than the other elements, is excluded from 

these plots to allow for improved y-axis scaling. 

Lawrenceville trace elements are generally dominated by crustal elements such 

as iron and silicon. The noticeable peak in the center is for potassium (date: 

7/5/04) and is likely due to fireworks on the previous day. The Lawrenceville site 

is 21⁄2 miles downwind of a large fireworks display that takes place annually in the 

downtown area on the 4th of July. 

Small chlorine peaks can occur at Lawrenceville during winter months (example: 

12/8/03), most likely due to the presence of road (rock) salt on streets near the 

monitor.
 18-Month Speciation 

May 2005 Page 21 

At Liberty, chlorine dominates the trace elements in addition to sulfur and 

therefore has been excluded from the graph below. 

[Note: scale is different than Lawrenceville graph.] 

Many elements such as crustal elements are present at Liberty like at 

Lawrenceville, but elements such as selenium and bromine show peaks that do 

not coincide with Lawrenceville. Similar to carbon and ammonium, many trace 

elements are part of the localized excess at Liberty. Comparing differences of 

each trace element should reveal dominant elements at each site. 
 18-Month Speciation 

May 2005 Page 22 

Below are average column graphs for each trace element. 

Sulfur is the most dominant element and is nearly equal for the sites. This 

follows the pattern of sulfate, which is also nearly equal on an average basis. 
 18-Month Speciation 

May 2005 Page 23 

Although not as prevalent as sulfur, copper and zirconium are also nearly equal. 

Hence, these elements can be classified as regional-only trace elements. 

The crustal elements in the chart below are constituents of fine soil. Collectively 

as a weighted sum, they compose the crustal component. 

The crustal component is higher at Lawrenceville, and this holds true for each 

crustal element except silicon. As an individual element, silicon could be 

classified as Liberty-dominant. For this report, silicon will be grouped with the 

crustal component as a whole. 
 18-Month Speciation 

May 2005 Page 24 

Potassium, sodium, and zinc are the most common Lawrenceville-dominant noncrustal trace elements. [Potassium and sodium are also measured as ions using 

the same analytical method by which the major species ammonium, nitrate, and 

sulfate are measured, but since the ionic concentrations of potassium and 

sodium are minute compared to the major ionic species, their trace element 

concentrations are given in this report.] 

Potassium is a major ingredient in fireworks, and 4th of July fireworks near 

downtown Pittsburgh are the likely cause of the larger concentration of potassium 

at Lawrenceville. The higher sodium concentration at Lawrenceville may be due 

to airborne road salt from more heavily traveled streets than at Liberty. Possible 

sources of additional zinc at Lawrenceville may be urban sources. 

Additional Lawrenceville-dominant trace elements are shown in the charts to 

follow. 
 18-Month Speciation 

May 2005 Page 25 

These Lawrenceville-dominant trace elements are likely urban and/or regional in 

nature. Barium, chromium, manganese, phosphorus, and tin show the most 

noticeable differences for these elements. 
 18-Month Speciation 

May 2005 Page 26 

Liberty-dominant trace elements are given below. 

Chlorine is the most common Liberty-dominant trace element. While chlorine is a 

component of road salt, the amount of excess chlorine is unlikely due to airborne 

road salt alone. 
 18-Month Speciation 

May 2005 Page 27 

Bromine is a halogen, like chlorine, although it is present at much smaller 

concentrations than chlorine. Arsenic, lead, mercury, and selenium are also 

noticeably higher trace elements at Liberty than at Lawrenceville, indicating 

possible local influences. 

Taking the Liberty-dominant trace elements into account, the Liberty localized 

excess pie chart can be adjusted to include chlorine and additional non-crustal 

trace elements in place of a portion of the "other" component. 

This adjusted localized excess pie chart represents the speciation of the Liberty 

excess, creating a PM2.5 fingerprint for the Liberty monitor. Without the excess 

PM2.5 components shown in the chart, Liberty would match Lawrenceville and be 

similar to other Eastern U.S. metropolitan sites. 
 18-Month Speciation 

May 2005 Page 28 

7. Species Correlations

Sulfate and nitrate generally exist as ammonium salts in PM2.5. Hence, 

correlations can be drawn between ammonium, nitrate, and sulfate, varying by 

season. 
 18-Month Speciation 

May 2005 Page 29 

The time series and regression plots for Lawrenceville sulfate and ammonium 

show a moderate correlation year-round. During warm months when sulfate is 

most prevalent, the correlation between ammonium and sulfate increases, but 

the slope of the regression line is similar to that of the year-round basis. A 

Lawrenceville ammonium and sulfate regression plot for May through October is 

given below. 

Sulfate commonly exists in two forms: ammonium sulfate and ammonium 

bisulfate. The slopes of the regression lines for Lawrenceville (0.274 – 0.279) 

are between that of a perfect ammonium sulfate regression (0.375) and a perfect 

ammonium bisulfate regression (0.188). So, a mixture of sulfate/bisulfate 

appears to be evident for Lawrenceville on a year-round basis. 
 18-Month Speciation 

May 2005 Page 30 

The times series plot for nitrate and ammonium shows the best correlation during 

winter when nitrates are more prevalent. The worst correlation occurs during 

warmer months when sulfates are more dominant. 

These trends for ammonium sulfate and ammonium nitrate salts are regional and 

are common to most speciation sites in the Eastern U.S. 
 18-Month Speciation 

May 2005 Page 31 

Trends for sulfate and ammonium at Liberty are given in the charts below. 
 18-Month Speciation 

May 2005 Page 32 

Liberty shows less of a year-round correlation for ammonium and sulfate than 

Lawrenceville, as the R2 (0.718) value is lower for the Liberty regression. Also, 

the slope is considerably greater for the Liberty regression line (0.458), due to 

the higher concentrations of ammonium at Liberty. 

To examine if sulfur is present as an element in any form other than sulfate at 

Liberty, time series and regression plots for Liberty sulfur and sulfate are shown 

below. 
 18-Month Speciation 

May 2005 Page 33 

Liberty sulfur and sulfate show an excellent correlation (0.954), so it can be 

assumed that very few additional forms of sulfur are present. 

Liberty behaves similarly to Lawrenceville for nitrate and ammonium, but with 

higher overall concentrations for ammonium at Liberty. Ammonium is likely 

present in other forms than just ammonium sulfate and nitrate salts at Liberty. 
 18-Month Speciation 

May 2005 Page 34 

One of the best correlations between species at either site is for organic carbon 

and elemental carbon at Liberty (R2

 = 0.928). Organic and elemental carbons 

also show strong correlations with total mass concentration at Liberty. Plots and 

correlations are shown below for organic carbon, elemental carbon, and total 

PM2.5. 
 18-Month Speciation 

May 2005 Page 35 
 18-Month Speciation 

May 2005 Page 36 
 18-Month Speciation 

May 2005 Page 37 

Additionally, chlorine can track organic carbon and ammonium in winter. Time 

series plots for chlorine with organic carbon and ammonium are given below. 

These plots suggest that chlorinated organic compounds and/or ammonium 

chloride salt may be a component of Liberty PM2.5 during cold months. 
 18-Month Speciation 

May 2005 Page 38 

Ammonium can also track the carbons on some days, specifically on peak days. 

Carbons, ammonium, and chlorine are shown on the following plot as "peak 

species." These species correlate well on peak days, but not necessarily yearround. 
 18-Month Speciation 

May 2005 Page 39 

On a smaller scale, some Liberty-dominant trace elements also appear to 

correlate with one another. Liberty arsenic, bromine, lead, and mercury are 

shown in the time series plot below. 

Lead may also correlate with selenium sometimes at Liberty, as shown in the plot 

below. 
 18-Month Speciation 

May 2005 Page 40 

Correlations of possible road (rock) salt trace elements at each site are shown 

next. Different forms of road (rock) salt can be used as ice-melting material. 

Sodium chloride is the cheapest, most common form and is the same chemical 

formula as table salt. Potassium chloride and calcium chloride can also be used 

as ice-melters, although calcium chloride is the most expensive salt and is 

generally used only on walkways. 

Mass ratios of the cation portion of each salt (sodium, potassium, calcium) are 

roughly 1:1 to the anionic portion (chloride). Plots of these elements should 

therefore show similar concentrations to one another if airborne road salt is a 

source of PM2.5. 

Road salt ingredients show similar concentration levels at Lawrenceville, 

signifying that one or more of the possible cations may be present with chloride 

as road salt. The highest chlorine peak (date: 12/8/03) may represent a 

combination of all three types of salt. 
 18-Month Speciation 

May 2005 Page 41 

Road salt ingredients at Liberty are shown in the plot below. 

At Liberty, road salt may be present as PM2.5, but only a small portion of the total 

chlorine concentrations can be attributed to road salt. The cation concentrations 

are much lower than chlorine on the peak days. Therefore, the source of 

chlorine is not entirely from road salt at Liberty. 
 18-Month Speciation 

May 2005 Page 42 

The Liberty site is collocated with several continuous monitors. Liberty 

continuous PM10 and PM2.5 are plotted below. 

The Liberty PM10 and PM2.5 continuous monitors correlate extremely well, with 

PM2.5 constituting two-thirds of the PM10 concentration. 
 18-Month Speciation 

May 2005 Page 43 

Regression plots for continuous gaseous pollutants and organic carbon (the most 

dominant PM2.5 species) are given below for Liberty. 

Hydrogen sulfide (H2S) 24-hour averages appear to correlate well with organic 

carbon at Liberty. Liberty benzene and organic carbon are shown next. 
 18-Month Speciation 

May 2005 Page 44 

Benzene itself is an organic carbon, but benzene 24-hour averages do not 

correlate well with organic carbon at Liberty. This is due to the different phases 

in which benzene and organic carbon are being sampled. The benzene monitor 

measures continuous gas-phase benzene, while the speciation monitor 

measures solid-phase organic carbon deposited over a 24-hour period. Gaseous 

benzene appears to behave differently than particulate-phase organic carbon on 

a 24-hour basis. 

[Benzene appears to follow organic carbon better on an hourly level. Hourly 

plots for continuous monitors are shown later in this report in the Peak Days 

section.] 

Liberty sulfur dioxide (SO2) and organic carbon are shown below. 

Sulfur dioxide, like benzene, does not correlate well with organic carbon on a 24-

hour basis. 
 18-Month Speciation 

May 2005 Page 45 

8. Site Correlations 

Liberty is located near two additional sites with PM10 and SO2 monitors: Lincoln 

and Glassport. Regression plots for these sites with Liberty are given below. 
 18-Month Speciation 

May 2005 Page 46 

These plots reveal that Liberty can correlate moderately with Glassport and 

Lincoln for PM10 on a 24-hour average basis. Liberty is more site-specific for 

SO2, however, as Glassport and Liberty do not correlate well. 
 18-Month Speciation 

May 2005 Page 47 

9. Liberty School Buses 

The Liberty site is located on the roof of South Allegheny High School, and 

school bus diesel emissions are a possible source of PM2.5 for that monitor. 

School buses line up on both sides of the high school in the morning and 

afternoon; the Liberty monitor is located near the center of the roof. 

The column chart below shows average concentrations of major species on a 

classes-in-session basis. On a day when classes are not in session and school 

buses are not present, diesel emissions from buses are not impacting the 

speciation monitor. 

This above chart represents year-round averages. However, PM2.5 can show a 

seasonal bias for certain species, such as sulfate in summer. To eliminate bias 

for summer days when classes are never in session, summer days can be 

removed from the averaging in order to show a more specific breakdown of 

species collected during the school year only.
 18-Month Speciation 

May 2005 Page 48 

The adjusted column chart above represents a more specific analysis of days 

with or without school bus emissions during the course of a school year (autumn 

through spring). 

It can be seen on the chart that all species except sulfate are higher during days 

when classes are in session. Diesel emissions are most commonly associated 

with elemental carbon. Since elemental carbon is indeed higher on class-days, 

school buses emissions may be impacting the Liberty monitor. However, higher 

concentrations for the additional species on class-days may suggest that the 

concentration differences are statistically random.
 18-Month Speciation 

May 2005 Page 49 

10. Days of the Week 

Below are column charts of average total PM2.5 concentrations for the continuous 

and speciation monitors. 

Total PM2.5 concentrations show some variance by day of the week. For the 

speciation monitor, there are no Friday samples on account of invalid retrieval 

times following a weekend. 
 18-Month Speciation 

May 2005 Page 50 

11. Liberty Peak Days 

Peak PM2.5 days usually occur simultaneously at Lawrenceville and Liberty, but 

the peaks have different species compositions and concentrations. 

Simultaneous peaking may be due to broad-scale inversions or other regional 

events. Liberty is much more greatly affected by inversions, however, as evident 

by the average hourly plot shown below. 

Liberty PM2.5 levels are highly influenced by nocturnal temperature inversions, 

when warmer upper-air layers trap pollutants close to surface level. 

Lawrenceville is moderately influenced by inversions near daybreak, but overall 

the levels remain steadier at Lawrenceville on a diurnal basis. 

Meteorological parameters and hourly multi-pollutant plots are shown on the 

following pages for selected peak days at Liberty. These peak days coincide 

with high carbon and ammonium concentrations. Additionally, high chlorine 

concentrations are present on cold-weather peak days. 

Benzene concentrations on the hourly plots represent gaseous benzene only. 

Resultant wind parameters represent the sum of the vector components. 

Persistence is the ratio of resultant wind speed to scalar mean (average) wind 

speed.

12. Conclusion 

Lawrenceville is affected by both regional flow and urban excess for PM2.5. The 

primary sources of the urban excess are from anthropogenic sources such as 

from light industry, residential and commercial heating, and mobile source 

emissions. The regional flow contribution is mostly attributed to upwind power 

plant emissions, but may also include PM2.5 from biogenic sources such as trees. 

At Liberty, regional flow is evident for some PM2.5 species, while concentrations 

of other species do not follow regional flow. It is assumed that species that do 

not follow regional flow may be attributed to sources resident to the area, both 

stationary and mobile. Liberty is more highly influenced by inversions than 

Lawrenceville. Carbons and ammonium are prominent species on peak days at 

Liberty. Chorine is also prominent on cold-weather peak days. 

To gain further understanding of PM2.5 in Allegheny County, future analysis may 

include the following: 

• Additional correlations 

• Deployment of additional monitors 

• Source testing 

• Dispersion modeling 

• Wind or other meteorological studies
