Blanchard (2004 and 2005a) examined weekend-weekday differences in ozone and NOx in the 

Midwest. All urban areas in these two studies exhibited substantially lower (40-60%) weekend 

concentrations of NOx compared to weekday concentrations. Despite lower weekend NOx

concentrations, weekend ozone concentrations were not lower; in fact, most urban sites had 

higher concentrations of ozone, although the increase was generally not statistically significant 

(see Figure 15). This small but counterproductive change in local ozone concentrations 

suggests that local urban-scale NOx reductions alone may not be very effective. 

Figure 15. Weekday/weekend differences in 8-hour ozone – number of sites with weekend 

increase (positive values) v. number of sites with weekend decreases (negative values)

Two additional analyses, however, demonstrate the positive effect of NOx emission reductions 

on downwind ozone concentrations. First, Blanchard (2005a) looked at the effect of changes in 

precursor emissions in Chicago on downwind ozone levels in western Michigan. For the 

transport days of interest (i.e., southwesterly flow during the summers of 1999 – 2002), mean 

NOx concentrations in Chicago are about 50% lower and mean ozone concentrations at the 

(downwind) western Michigan sites are about 1.5 – 5.2 ppb (3 – 8 %) lower on Sunday 

compared to Wednesday. This degree of change in downwind ozone levels suggests a 

positive, albeit non-linear response to urban area emission reductions.

Second, Environ (2007a) examined the effect of differences in day-of-week emissions in 

southeastern Michigan on downwind ozone levels. This modeling study found that weekend 

changes in ozone precursor emissions cause both increases and decreases in Southeast 

Michigan ozone, depending upon location and time:
21

• Weekend increases in 8-hour maximum ozone occur in and immediately downwind of 

the Detroit urban area (i.e., in VOC-sensitive areas).

• Weekend decreases in 8-hour maximum ozone occur outside and downwind of the 

Detroit urban area (i.e., in NOx-sensitive areas).

• At the location of the peak 8-hour ozone downwind of Detroit, ozone was lower on 

weekends than weekdays.

• Ozone benefits (reductions) due to weekend emission changes in Southeast Michigan 

can be transported downwind for hundreds of miles.

• Southeast Michigan benefits from lower ozone transported into the region on Saturday

through Monday because of weekend emission changes in upwind areas.

In summary, these analyses suggest that urban VOC reductions and regional (urban and rural) 

NOx reductions will be effective in lowering ozone concentrations. Local NOx reductions can 

lead to local ozone increases (i.e., NOx disbenefits), but this effect does not appear to pose a 

problem with respect to attainment of the standard. It should also be noted that urban VOC and 

regional NOx reductions are likely to have multi-pollutant benefits (e.g., both lower ozone and 

PM2.5 impacts).

2.2 PM2.5

In 1997, EPA adopted the PM2.5 standards of 15 ug/m

3

 (annual average) and 65 ug/m3 (24-hour 

average). The annual standard is attained if the 3-year average of the annual average PM2.5

concentration is less than or equal to the level of the standard. The daily standard is attained if 

the 98th percentile of 24-hour PM2.5 concentrations in a year, averaged over three years, is less 

than or equal to the level of the standard.

In 2006, EPA revised the PM2.5 standards to 15 ug/m3 (annual average) and 35 ug/m3 (24-hour 

average). 

Current Conditions: Maps of annual and 24-hour PM2.5 design values for the 3-year period 

2005-2007 are shown in Figure 16. The “hotter” colors represent higher concentrations, where 

red dots represent sites with design values above the annual standard. Currently, there are 30

sites in violation of the annual PM2.5 standard.

When EPA initially set the 24-hour standard at 65 μg/m3, it also adopted the following 

concentration ranges for its Air Quality Index (AQI) scale:

Good < 15 ug/m3

Moderate 15-40 μg/m3

Unhealthy for Sensitive Groups (USG) 40-65 μg/m3

Unhealthy 65-150 μg/m3

Figure 17 shows the frequency of these AQI categories for major metropolitan areas in the 

region. Daily average concentrations are often in the moderate range and occasionally in the 

USG range. Moderate and USG levels can occur any time of the year. 

Figure 17. Percent of days in AQI categories for PM2.5 (2002-2004)

Data Variability: PM2.5 concentrations vary spatially, temporally, and chemically in the region. 

This variability is discussed further below.

On an annual basis, PM2.5 exhibits a distinct and consistent spatial pattern. As seen in Figure 

16, across the Midwest, annual concentrations follow a gradient from low values (5-6 μg/m3) in 

northern and western areas (Minnesota and northern Wisconsin) to high values (17-18 μg/m3) in 

Ohio and along the Ohio River. In addition, concentrations in urban areas are higher than in 

upwind rural areas, indicating that local urban sources add a significant increment of 2-3 μg/m3

to the regional background of 12 - 14 μg/m3 (see Figure 18).

concentrations
25

Because monitoring for PM2.5 only began in earnest in 1999, after promulgation of the PM2.5

standard, limited data are available to assess trends. Time series based on federal reference 

method (FRM) PM2.5-mass data show a downward trend in each state (see Figure 19)

7

.

Figure 19. PM2.5 trends in annual average (top) and daily concentrations (bottom)

 

7

 Despite the general downward trend since 1999, all states experienced an increase during 2005. 

Further analyses are underway to understand this increase (e.g., examination of meteorological and 

emissions effects).
26

A statistical analysis of PM2.5 trends was performed using the nonparametric Theil test for slope 

(Hollander and Wolfe, 1973). Trends were generally consistent around the region, for both PM 

mass and for the individual components of mass. Figure 20 shows trends for PM2.5 based on 

FRM data at sites with six or more years of data since 1999. The size and direction of each 

arrow shows the size and direction of the trend for each site; solid arrows show statistically 

significant trends and open arrows show trends that are not significant. Region-wide decreases 

are widespread and consistent; all sites had decreasing concentration trends (13 of the 38 were 

statistically significant). The average decrease for this set of sites is -0.24 ug/m3/year. 

Figure 20. Annual trends in PM2.5 mass (1999 – 2006)

Seasonal trends show mostly similar patterns (Figure 21). Trends were downward at most sites 

and seasons, with overall seasonal averages varying between -0.15 to -0.56 ug/m3/year. The 

strongest and most significant decreases took place during the winter quarter (January - March). 

No statistically significant increasing trends were observed.
27

Figure 21. Seasonal trends in PM2.5 mass (1999 – 2006)

PM2.5 shows a slight variation from weekday to weekend, as seen in Figure 22. Although most 

cities have slightly lower concentrations on the weekend, the difference is usually less than 1 

μg/m3. There is a more pronounced weekday/weekend difference at monitoring sites that are 

strongly source-influenced. Rural monitors tend to show less of a weekday/weekend pattern 

than urban monitors.

Figure 22 Day-of-week variability in PM2.5 (2002-2004)
28

In the Midwest, PM2.5 is made up of mostly ammonium sulfate, ammonium nitrate, and organic 

carbon in approximately equal proportions on an annual average basis. Elemental carbon and 

crustal matter (also referred to as soil) contribute less than 5% each. 

Figure 23. Spatial map of PM2.5 chemical composition in the Midwest (2002-2003)

The three major components vary spatially (Figure 23), including notable urban and rural 

differences (Figure 24). The components also vary seasonally (Figure 25). These patterns 

account for much of the annual variability in PM2.5 mass noted above.

29

Figure 25 Seasonal and spatial variability in PM2.5 components
30

Ammonium sulfate peaks in the summer and is highest in the southern and eastern parts of the 

Midwest, closest to the Ohio River Valley. Sulfate is primarily a regional pollutant; 

concentrations are similar in rural and urban areas and highly correlated over large distances. It 

is formed when sulfuric acid (an oxidation product of sulfur dioxide) and ammonia react in the 

atmosphere, especially in cloud droplets. Coal combustion is the primary source of sulfur 

dioxide; ammonia is emitted primarily from animal husbandry operations and fertilizer use.

Ammonium nitrate has almost the opposite spatial and seasonal pattern, with the highest 

concentrations occurring in the winter and in the northern parts of the region. Nitrate seems to 

have both regional and local sources, because urban concentrations are higher than rural 

upwind concentrations. Ammonium nitrate forms when nitric acid reacts with ammonia, a 

process that is enhanced when temperatures are low and humidity is high. Nitric acid is a 

product of the oxidation of nitric oxide, a pollutant that is emitted by combustion processes.

Organic carbon is more consistent from season to season and city to city, although 

concentrations are generally slightly higher in the summer. Like nitrate, organic carbon has 

both regional and local components. Particulate organic carbon can be emitted directly from 

cars and other fuel combustion sources or formed in a secondary process as volatile organic 

gases react and condense. In rural areas, summer organic carbon has significant contributions 

from biogenic sources.

Precursor Sensitivity: Data from the Midwest ammonia monitoring network were analyzed with 

thermodynamic equilibrium models to assess the effect of changes in precursor gas 

concentrations on PM2.5 concentrations (Blanchard, 2005b). These analyses indicate that 

particle formation responds in varying degrees to reductions in sulfate, nitric acid, and ammonia. 

Based on Figure 26, which shows PM2.5 concentrations as a function of sulfate, nitric acid 

(HNO3), and ammonia (NH3), several key findings should be noted: 

• PM2.5 mass is sensitive to reductions in sulfate at all times of the year and all parts of the 

region. Even though sulfate reductions cause more ammonia to be available to form 

ammonium nitrate (PM-nitrate increases slightly when sulfate is reduced), this increase 

is generally offset by the sulfate reductions, such that PM2.5 mass decreases.

• PM2.5 mass is also sensitive to reductions in nitric acid and ammonia. The greatest PM2.5

decrease in response to nitric acid reductions occurs during the winter, when nitrate is a

significant fraction of PM2.5.

• Under conditions with lower sulfate levels (i.e., proxy of future year conditions), PM2.5 is 

more sensitive to reductions in nitric acid compared to reductions in ammonia.

• Ammonia becomes more limiting as one moves from west to east across the region.

Examination of weekend/weekday difference in PM-nitrate and NOx concentrations in the 

Midwest demonstrate that reductions in local (urban) NOx lead to reductions, albeit nonproportional reductions, in PM-nitrate (Blanchard, 2004). This result is consistent with analyses 

of continuous PM-nitrate from several US cities, including St. Louis (Millstein, et al, 2007). 
31

(bottom) as functions of changes in sulfate, nitric acid (HNO3), and ammonia (NH3)

Note: starting at the baseline values (represented by the red star), either moving downward (reductions in nitric 

acid) or moving leftward (reductions in sulfate or ammonia) results in lower PM2.5 values
32

Meteorology: PM2.5 concentrations are not as strongly influenced by meteorology as ozone, but 

the two pollutants share some similar meteorological dependencies. In the summer, conditions 

that are conducive to ozone (hot temperatures, stagnant air masses, and low wind speeds due 

to stationary high pressure systems) also frequently give rise to high PM2.5. In the case of PM,

the reason is two-fold: (1) stagnation and limited mixing under these conditions cause PM2.5 to 

build up, usually over several days, and (2) these conditions generally promote higher 

conversion of important precursors (SO2 to SO4) and higher emissions of some precursors, 

especially biogenic carbon. Wind direction is another strong determinant of PM2.5; air 

transported from polluted source regions has higher concentrations.

Unlike ozone, PM2.5 has occasional winter episodes. Conditions are similar to those for summer 

episodes, in that stationary high pressure and (seasonally) warm temperatures are usually 

factors. Winter episodes are also fueled by high humidity and low mixing heights. 

PM2.5 chemical species show noticeable transport influences. Trajectory analyses have 

demonstrated that high PM-sulfate is associated with air masses that traveled through the 

sulfate-rich Ohio River Valley (Poirot, et al, 2002 and Kenski, 2004). Likewise, high PM-nitrate 

is associated with air masses that traveled through the ammonia-rich Midwest. Figure 27

shows results from an ensemble trajectory analysis of 17 rural eastern IMPROVE sites. 

Figure 27. Sulfate and nitrate source regions based on ensemble trajectory analysis

When these results are considered together with analyses of precursor sensitivity (e.g., Figure 

26), one possible conclusion is that ammonia control in the Midwest could be effective at 

reducing nitrate concentrations. The thermodynamic equilibrium modeling shows that ammonia 

reductions would reduce PM concentrations in the Midwest, but that nitric acid reductions are 

more effective when the probable reductions in future sulfate levels are considered. 
33

Source Culpability: Three source apportionment studies were performed using speciated PM2.5

monitoring data and statistical analysis methods (Hopke, 2005, STI, 2006, and STI, 2008). 

Figure 28 summarizes the source contributions from these studies. The studies show that a

large portion of PM2.5 mass consists of secondary, regional impacts, which cannot be attributed 

to individual facilities or sources (e.g., secondary sulfate, secondary nitrate, and secondary 

organic aerosols). Nevertheless, wind analyses (e.g., Figure 27) provide information on likely 

source regions. Regional- or national-scale control programs may be the most effective way to 

deal with these impacts. EPA's CAIR, for example, will provide for substantial reductions in 

SO2 emissions over the eastern half of the U.S., which will reduce sulfate (and PM2.5) 

concentrations and improve visibility levels.

The studies also show that a smaller, yet significant portion of PM2.5 mass is due to emissions 

from nearby (local) sources. Local (urban) excesses occur in many urban areas for organic and 

elemental carbon, crustal matter, and, in some cases, sulfate. The statistical analysis methods 

help to identify local sources and quantify their impact. This information is valuable to states 

wishing to develop control programs to address local impacts. A combination of 

national/regional-scale and local-scale emission reductions may be necessary to provide for 

attainment.

The carbon sources are not easily identified in complex urban environments. LADCO’s Urban 

Organics Study (STI, 2006) identified four major sources of organic carbon: mobile sources, 

burning, industrial sources, and secondary organic aerosols. Additional sampling and analysis 

is underway in Cleveland and Detroit to provide further information on sources of organic 

carbon.

2.3 Haze

Section 169A of the Clean Air Act sets as a national goal “the prevention of any future, and the 

remedying of any existing, impairment of visibility in mandatory Class I Federal areas which 

impairment results from manmade air pollution”. To implement this provision, in 1999, EPA 

adopted regulations to address regional haze visibility impairment (USEPA, 1999). EPA’s rule 

requires states to “make reasonable progress toward meeting the national goal”. Specifically, 

states must establish reasonable progress goals, which provide for improved visibility on the 

most impaired (20% worst) days sufficient to achieve natural conditions by the year 2064, and 

for no degradation on the least impaired (20% best) days.

The primary cause of impaired visibility in the Class I areas is pollution by fine particles that 

scatter light. The degree of impairment, which is expressed in terms of visual range, light 

extinction (1/Mm), or deciviews (dv), depends not just on the total PM2.5 mass concentration, but 

also on the chemical composition of the particles and meteorological conditions.

Current Conditions: A map of the average light extinction values for the most impaired (20% 

worst) visibility days for the 5-year baseline period (2000-2004) is shown in Figure 29. 

Figure 29. Baseline Visibility Levels for 20% Worst Days (2000 – 2004), units: Mm-1
36

Initially, the baseline (2000 – 2004) visibility condition values were derived using the average for 

the 20% worst and 20% best days for each year, as reported on the VIEWS website: 

http://vista.cira.colostate.edu/views/Web/IMPROVE/SummaryData.aspx . These values were 

calculated using the original IMPROVE equation for reconstructed light extinction.

Three changes were made to the baseline calculations to produce a new set of values. First, 

the reconstructed light extinction equation was revised by the IMPROVE Steering Committee in 

2005. The new IMPROVE equation was used to calculate updated baseline values. 

Second, due to sampler problems, the 2002-2004 data for Boundary Waters were invalid for 

certain chemical species. (Note, sulfate and nitrate data were valid.) A “substituted” data set 

was developed by using values from Voyageurs for the invalid species.

Third, LADCO identified a number of days during 2000-2004 where data capture at the Class I

monitors was incomplete (Kenski, 2007b). The missing data cause these days to be excluded 

from the baseline calculations. However, the light extinction due to the remaining measured 

species is significant (i.e., above the 80th percentile). It makes sense to include these days in 

the baseline calculations, because they are largely dominated by anthropogenic sources. (Only 

one of these days is driven by high organic carbon, which might indicate non-anthropogenic 

aerosol from wildfires.) As seen in Table 3, inclusion of these days in the baseline calculation

results in a small, but measurable, effect on the baseline values (i.e., values increase from 0.2 

to 0.8 dv).

As noted above, the goal of the visibility program is to achieve natural conditions. Initially, the 

natural conditions values for each Class I area were taken directly from EPA guidance (EPA, 

2003). These values were calculated using the original IMPROVE equation. This equation was 

revised by the IMPROVE Steering Committee in 2005, and the new IMPROVE equation was 

used to calculate updated natural conditions values. The updated values are reported on the 

VIEWS website.

A summary of the initial and updated natural conditions values are presented in Table 4. The 

updated natural conditions values (based on the new IMPROVE equation) will be used for SIP 

planning purposes.

Data Variability: For the four northern Class I areas, the most important PM2.5 chemical species 

are ammonium sulfate, ammonium nitrate, and organic carbon. The contribution of these 

species on the 20% best and 20% worst visibility days (based on 2000 – 2004 data) is provided 

in Figure 30. For the 20% worst visibility days, the contributions are: sulfate = 35-55%, nitrate = 

25-30%, and organic carbon = 12-22%. Although the chemical composition is similar, sulfate 

increases in importance from west to east and concentrations are highest at Seney (the 

easternmost site). It should also be noted that sulfate and nitrate contribute more to light 

extinction than to PM2.5 mass because of their hygroscopic properties.

Analysis of PM2.5 mass and chemical species for rural IMPROVE (and IMPROVE-protocol) sites 

in the eastern U.S. showed a high degree of correlation between PM2.5-mass, sulfate, and 

nitrate levels (see Figure 31). The Class I sites in northern Michigan and northern Minnesota, in 

particular, are highly correlated for PM2.5 mass, sulfates, and organic carbon mass (AER, 2004).
39

Figure 31. Correlations among IMPROVE (and IMPROVE-protocol) monitoring sites in Eastern U.S.

Long-term trends at Boundary Waters (the only regional site with a sufficient data record) show 

significant decreases in total PM2.5 (-0.005 ug/year) and SO4 (-0.04 ug/year) and an increase in 

NO3 (+0.01 ug/year). These PM2.5 and SO4 trends are generally consistent with long-term 

trends at other IMPROVE sites in the eastern U.S., which have shown widespread decreases in 

SO4 and PM2.5 (DeBell, et al, 2006). Detecting changes in nitrate has been hampered by 

uncertainties in the IMPROVE data for particular years and, thus, this estimate should be 

considered tentative. 

Haze in the Midwest Class I areas has no strong seasonal pattern. Poor visibility days occur 

throughout the year, as indicated in Figure 32. (Note, in contrast, other parts of the country, 

such as Shenandoah National Park in Virginia, show a strong tendency for the worst air quality 

days to occur in the summer months.) This figure and Figure 33 (which presents the monthly 

average light extinction values based on all sampling days) also show that sulfate and organic 

carbon concentrations are higher in the summer, and nitrate concentrations are higher in the 

winter, suggesting the importance of different sources and meteorological conditions at different 

times of the year.

Precursor Sensitivity: Results from two analyses using thermodynamic equilibrium models 

provide information on the effect of changes in precursor concentrations on PM2.5

concentrations (and, in turn, visibility levels) in the northern Class I areas. First, a preliminary 

analysis using data collected at Seney indicated that PM2.5 there is most sensitive to reductions 

in sulfate, but is also sensitive to reductions in nitric acid (Blanchard, 2004). 

Second, an analysis was performed using data from the Midwest ammonia monitoring network

for a site in Minnesota -- Great River Bluffs, which is the closest ammonia monitoring site to the 

northern Class I areas (Blanchard, 2005b). Figure 34 shows PM2.5 concentrations as a function 

of sulfate, nitric acid (HNO3), and ammonia (NH3). Reductions in sulfate (i.e., movement to the 

left of baseline value [represented by the red star]), as well as reductions in nitric acid (i.e., 

movement downward) and NH3 (i.e., movement to the left), result in lower PM2.5 concentrations. 

Thus, reductions in sulfate, nitric acid, and ammonia will lower PM2.5 concentrations and 

improve visibility in the northern Class I areas.

Figure 34. Predicted PM2.5 mass concentrations at Great River Bluffs, MN as functions of changes 

in sulfate, nitric acid, and ammonia

Meteorology and Transport: The role of meteorology in haze is complex. Wind speed and wind 

direction govern the movement of air masses from polluted areas to the cleaner wilderness 

areas. As noted above, increasing humidity increases the efficiency with which sulfate and 

nitrate aerosols scatter light. Temperature and humidity together govern whether ammonium 

nitrate can form from its precursor gases, nitric acid and ammonia. Temperature and sunlight 

also play an indirect role in emissions of biogenic organic species that condense to form 

particulate organic matter; emissions increase in the summer daylight hours. 

Trajectory analyses were performed to understand transport patterns for the 20% worst and 

20% best visibility days. The composite results for the four northern Class I areas are provided 

in Figure 35. The orange areas are where the air is most likely to come from, and the green 

areas are where the air is least likely to come from. As can be seen, bad air days are generally 

associated with transport from regions located to the south, and good air days with transport 

from Canada. 
43

20% worst visibility days (right) (2000 – 2005)

Source Culpability: Air quality data analyses (including the trajectory analyses above) and 

dispersion modeling were used to provide information on source region and source sector 

contributions to regional haze in the northern Class I areas (see MRPO, 2008). Based on this 

information, the most important contributing states are Michigan, Minnesota, and Wisconsin, as 

well as Missouri, North Dakota, Iowa, Indiana and Illinois (see, for example, Figure 35 above). 

The most important contributing pollutants and source sectors are SO2 emissions from 

electrical generating units (EGUs) and certain non-EGUs, which lead to sulfate formation, and 

NOx emissions from a variety of source types (e.g., motor vehicles), which lead to nitrate 

formation. Ammonia emissions from livestock waste and fertilizer applications are also 

important, especially for nitrate formation.

A source apportionment study was performed using monitoring data from Boundary Waters and 

statistical analysis methods (DRI, 2005). The study shows that a large portion of PM2.5 mass 

consists of secondary, regional impacts, which cannot be attributed to individual facilities or 

sources (e.g., secondary sulfate, secondary nitrate, and secondary organic aerosols). Industrial 

sources contribute about 3-4% and mobile sources about 4-7% to PM2.5 mass. 

A special study was performed in Seney to identify sources of organic carbon (Sheesley, et al, 

2004). As seen in Figure 36, the highest PM2.5 concentrations occurred during the summer, 

with organic carbon being the dominant species. The higher summer organic carbon 

concentrations were attributed mostly to secondary organic aerosols of biogenic origin because 

of the lack of primary emission markers, and concentrations of know biogenic-related species 

(e.g., pinonic acid – see Figure 36) were also high during the summer.
44

organic carbon species in Seney (bottom)
45

Although the Seney study showed that biomass burning was a relatively small contributor to 

organic carbon on an annual average basis, episodic impacts are apparent (see, for example, 

high organic carbon days in Figure 32). To assess further whether burning is a significant 

contributor to visibility impairment in the northern Class I areas, the PM2.5 chemical speciation 

data were examined for days with high organic carbon and elemental carbon concentrations, 

which are indicative of biomass burning impacts. Only a handful of such days were identified:

Table 5. Days with high OC and EC concentrations in northern Class I areas

Isle Royale --- --- Jun 1 Aug 25 ---

Back trajectories on these days point mostly to wildfires in Canada. Elimination of these high 

organic carbon concentration days has a small effect in lowering the baseline visibility levels in 

the northern Class I areas (i.e., Minnesota Class I areas change by about 0.3 deciviews and 

Michigan Class I areas change by less than 0.2 deciviews). This suggests that fire activity, 

although significant on a few days, is on average a relatively small contributor to visibility 

impairment in the northern Class I areas.

In summary, these analyses show that organic carbon in the northern Class I is largely 

uncontrollable.
46

Section 3.0 Air Quality Modeling

Air quality models are relied on by federal and state regulatory agencies to support their 

planning efforts. Used properly, models can assist policy makers in deciding which control 

programs are most effective in improving air quality, and meeting specific goals and objectives. 

For example, models can be used to conduct “what if” analyses, which provide information for 

policy makers on the effectiveness of candidate control programs.

The modeling analyses were conducted in accordance with EPA’s modeling guidelines (EPA, 

2007a). Further details of the modeling are provided in two protocol documents: LADCO, 2007a 

and LADCO, 2007b. 

This section reviews the development and evaluation of the modeling system used for the multipollutant analyses. Application of the modeling system (i.e., attainment demonstration for ozone 

and PM2.5, and reasonable progress assessment for haze) is covered in the following sections.

3.1 Selection of Base Year

Two base years were used in the modeling analyses: 2002 and 2005. EPA’s modeling 

guidance recommends using 2002 as the baseline inventory year, but also allows for use of an 

alternative baseline inventory year, especially a more recent year. Initially, LADCO conducted 

modeling with a 2002 base year (i.e., Base K/Round 4 modeling, which was completed in 2006). 

A decision was subsequently made to conduct modeling with a 2005 base year (i.e., Base 

M/Round 5, which was completed in 2007). As discussed in the previous section, 2002 and 

2005 both had above normal ozone conducive conditions, although 2002 was more severe 

compared to 2005. Examination of multiple base years provides for a more complete technical 

assessment. Both sets of model runs are discussed in this document. 

3.2 Future Years of Interest

To address the multiple attainment requirements for ozone and PM2.5, and reasonable progress 

goals for regional haze, several future years are of interest:

2008 Planning year for ozone basic nonattainment areas (attainment date 2009)8

2009 Planning year for ozone moderate nonattainment areas and PM2.5 nonattainment 

areas (attainment date 2010)

2012 Planning year for ozone moderate nonattainment areas and PM2.5 nonattainment 

areas, with 3-year extension (attainment date 2013)

2018 First milestone year for regional haze planning

 

8

According to USEPA’s ozone implementation rule (USEPA, 2005), emission reductions needed for 

attainment must be implemented by the beginning of the ozone season immediately preceding the area’s 

attainment date. The PM2.5 implementation rule contains similar provisions – i.e., emission reductions 

should be in place by the beginning of the year preceding the attainment date (USEPA, 2007c). The logic 

for requiring emissions reductions by the year (or season) immediately preceding the attainment year 

follows from language in the Clean Air Act, and the ability for an area to receive up to two 1-year 

extensions. Therefore, emissions in the year preceding the attainment year should be at a level that is 

consistent with attainment. It also follows that the year preceding the attainment year should be modeled 

for attainment planning purposes.
47

Detailed emissions inventories were developed for 2009 and 2018. To support modeling for 

other future years, less rigorous emissions processing was conducted (e.g., 2012 emissions 

were estimated for several source sectors by interpolating between 2009 and 2018 emissions).

3.3 Modeling System

The air quality analyses were conducted with the CAMx model, with emissions and meteorology 

generated using EMS (and CONCEPT) and MM5, respectively. The selection of CAMx as the 

primary model is based on several factors: performance, operator considerations (e.g., ease of 

application and resource requirements), technical support and documentation, model 

extensions (e.g., 2-way nested grids, process analysis, source apportionment, and plume-ingrid), and model science. CAMx model set-up for Base M and Base K is summarized below:

Base M (2005) Base K (2002)

• CAMx v4.50 * CAMx 4.30

• CB05 gas phase chemistry * CB-IV with updated gas-phase chemistry

• SOA chemistry updates * No SOA chemistry updates

• AERMOD dry deposition scheme * Wesley-based dry deposition

• ISORROPIA inorganic chemistry • ISORROPIA inorganic chemistry

• SOAP organic chemistry • SOAP organic chemistry

• RADM aqueous phase chemistry • RADM aqueous phase chemistry

• PPM horizontal transport • PPM horizontal transport

3.4 Domain/Grid Resolution

The National RPO grid projection was used for this modeling. A subset of the RPO domain was 

used for the LADCO modeling. For PM2.5 and haze, the large eastern U.S. grid at 36 km (see 

box on right side of Figure 36) was used. A PM2.5 sensitivity run was also performed for this 

domain at 12 km. For ozone, the smaller grid at 12 km (see shaded portion of the box on the 

right side of Figure 37) was used for most model runs. An ozone sensitivity run was also 

performed with a 4km sub-grid over the Lake Michigan area and Detroit/Cleveland.

The vertical resolution in the air quality model consists of 16 layers extending up to 15 km, with 

higher resolution in the boundary layer.

3.5 Model Inputs: Meteorology

Meteorological inputs were derived using the Fifth-Generation NCAR/Penn State Meteorological 

Model (MM5) – version 3.6.3 for the years 2001–2003, and version 3.7 for the year 2005. The 

MM5 modeling domains are consistent with the National RPO grid projections (see Figure 38). 

Figure 38. MM5 modeling domain for 2001-2003 (left) and 2005 (right)

The annual 2002 36 km MM5 simulation was completed by Iowa DNR. The 36/12 km 2-way 

nested simulation for the summers of 2001, 2002, and 2003 were conducted jointly by Illinois 

EPA and LADCO. The 36 km non-summer portion of the annual 2003 simulation was conducted 

by Wisconsin DNR. The annual 2005 36/12 km (and summer season 4 km) MM5 modeling was 

completed by Alpine Geophysics. Wisconsin DNR also completed 36/12 km MM5 runs for the 

summer season of 2005.

Model performance was assessed quantitatively with the METSTAT tool from Environ. The 

metrics used to quantify model performance include mean observation, mean prediction, bias, 

gross error, root mean square error, and index of agreement. Model performance metrics were 

calculated for several sub-regions of the modeling domain (Figure 39) and represent hourly 

spatial averages of multiple monitor locations. Additional analysis of rainfall is done on a 

monthly basis.

Figure 39. Sub-domains used for model performance for 2001-2003 (left) and 2005 (right)

A summary of the performance evaluation results for the meteorological modeling is provided 

below. Further details are provided in two summary reports (LADCO, 2005 and LADCO, 2007c).
49

Temperature: The biggest issue with the performance in the upper Midwest is the existence of a 

cool diurnal temperature bias in the winter and warm temperature bias over night during the 

summer (see Figure 40). These features are common to other annual MM5 simulations for the 

central United States and do not appear to adversely affect model performance. 

Figure 40. Daily temperature bias for 2002 (left) and 2005 (right) with hotter colors 

(yellow/orange/red) representing overestimates and cooler colors (blues) representing 

underestimates

Note: months are represented from left to right (January to December) and days are represented 

from top to bottom (1 to 30(31) – i.e., upper left hand corner is January 1 and lower right hand 

corner is December 31

Wind Fields: The wind fields are generally good. Wind speed bias is less than 0.5 m/sec and 

wind speed error is consistently between 1.0 and 1.5 m/sec. Wind direction error is generally 

within 15-30 degrees.

Mixing Ratio: The mixing ratio (a measure of humidity) is over-predicted in the late spring and 

summer months, and mixing ratio error is highest during this period. There is little bias and 

error during the cooler months when there is less moisture in the air.

Rainfall: The modeled and observed rainfall totals show good agreement spatially and in

terms of magnitude in the winter, fall, and early spring months. There are, however, large overpredictions of rainfall in the late spring and summer months (see Figure 41). These overpredictions are seen spatially and in magnitude over the entire domain, particularly in the 

Southeast United States, and are likely due to excessive convective rainfall being predicted in 

MM5. This over-prediction of rainfall in MM5 does not necessarily translate into over-prediction 

of wet deposition in the photochemical model. CAMx does not explicitly use the convective and 

non-convective rainfall output by MM5, but estimates wet scavenging by hydrometeors using 

cloud, ice, snow, and rain water mixing ratios output by MM5. Nevertheless, this could have an 

effect on model performance for PM2.5, as discussed in Section 3.7, and may warrant further 

attention.

3.6 Model Inputs: Emissions

Emission inventories were prepared for two base years: 2002 (Base K) and 2005 (Base M), and 

several future years: 2008, 2009, 2012, and 2018. Further details of the emission inventories 

are provided in two summary reports (LADCO, 2006a and LADCO, 2008a) and the following 

pages of the LADCO web site:

http://www.ladco.org/tech/emis/basek/BaseK_Reports.htm

http://www.ladco.org/tech/emis/r5/round5_reports.htm

For on-road, nonroad, ammonia, and biogenic sources, emissions were estimated by models. 

For the other sectors (point sources, area sources, and MAR [commercial marine, aircraft, and 

railroads]), emissions were prepared using data supplied by the LADCO States and other 

RPOs.

Base Year Emissions: State and source sector emission summaries for 2002 (Base K) and 

2005 (Base M) are compared in Figure 42. Additional detail is provided in Tables 6a (all sectors 

– tons per day) and 6b (EGUs – tons per year).

On-road Sources: For 2002, EMS was run by LADCO using VMT and MOBILE6 inputs supplied 

by the LADCO States. EMS was run to generate 36 days (weekday, Saturday, Sunday for each 

month) at 36 km, and 9 days (weekday, Saturday, Sunday for June – August) at 12 km. For 

2005, CONCEPT was run by a contractor (Environ) using transportation data (e.g., VMT and 

vehicle speeds) supplied by the state and local planning agencies in the LADCO States and 

Minnesota for 24 networks. These data were first processed with T3 (Travel Demand Modeling 

[TDM] Transformation Tool) to provide input files for CONCEPT to calculate link-specific, hourly 

emission estimates (Environ, 2008). CONCEPT was run with meteorological data for a July and 

January weekday, Saturday, and Sunday (July 15 – 17 and January 16 – 18). A spatial plot of 

emissions is provided in Figure 43.

VOC Emissions NOx Emissions

Figure 43. Motor vehicle emissions for VOC (left) and NOx (right) for a July weekday (2005)

Off-road Sources: For 2002 and 2005, NMIM and NMIM2005, respectively, were run by 

Wisconsin DNR. Additional off-road sectors (i.e., commercial marine, aircraft, and railroads 

[MAR]) were handled separately. Local data for agricultural equipment, construction equipment, 

commercial marine, recreational marine, and railroads were prepared by contractors (Environ, 

2004, and E.H. Pechan, 2004). For Base M, updated local data for railroads and commercial 

marine were prepared by a contractor (Environ, 2007b, 2007c). Table 7 compares the Base M

2005 and Base K 2002 emissions. Compared to 2002, the new 2005 emissions reflect 

substantially lower commercial marine emissions and lower locomotive NOx emissions.

Area Sources: For 2002 and 2005, EMS was run by LADCO using data supplied by the LADCO 

States to produce weekday, Saturday, and Sunday emissions for each month. For 2005, 

special attention was given to two source categories: industrial adhesive and sealant solvents 

(which were dropped from the inventory to avoid double-counting) and outdoor wood boilers

(which were added to the inventory).

Point Sources: For 2002 and 2005, EMS was run by LADCO using data supplied by the LADCO 

States to produce weekday, Saturday, and Sunday emissions for each month. For EGUs, the 

annual and summer season emissions were temporalized for modeling purposes using profiles 

prepared by Scott Edick (Michigan DEQ) based on CEM data. 

 

Biogenics: For Base M, a contractor (Alpine) provided an updated version of the 

CONCEPT/MEGAN biogenics model. Compared to the previous (EMS/BIOME) emissions, 

there is more regional isoprene using MEGAN compared to the BIOME estimates used for Base 

K (see Figure 44). Also, with the secondary organic aerosol updates to the CAMx air quality 

model, Base M includes emissions for monoterpenes and sesquiterpenes, which are precursors of secondary PM2.5 organic carbon mass.

Figure 44. Isoprene emissions for Base M (left) v. Base K (right)

Ammonia: For Base M, the CMU-based 2002 (Base K) ammonia emissions were projected to 

2005 using growth factors from the Round 4 emissions modeling. These emissions were then 

adjusted by applying temporal factors by month based on the process-based ammonia 

emissions model (Zhang, et al, 2005, and Mansell, et al, 2005). A plot of average daily 

emissions by state and month is provided in Figure 45. A spatial plot of emissions is provided in 

Figure 46, which shows high emissions densities in the central U.S.

Canadian Emissions: For Base M, Scott Edick (Michigan DEQ) processed the 2005 Canadian 

National Pollutant Release Inventory, Version 1.0 (NPRI). Specifically, a subset of the NPRI 

data (emissions and stack parameters) relevant to the air quality modeling were reformatted. 

The resulting emissions represent a significant improvement in the base year emissions. 

A spatial plot of point source SO2 and NOx emissions is provided in Figure 47. Additional plots 

and emission reports are available on the LADCO website 

(http://www.ladco.org/tech/emis/basem/canada/index.htm).

Fires: For Base K, a contractor (EC/R, 2004) developed a 2001, 2002, and 2003 fire emissions 

inventory for eight Midwest States (five LADCO states plus Iowa, Minnesota, and Missouri), 

including emissions from wild fires, prescribed fires, and agricultural burns. Projected emissions 

were also developed for 2010 and 2018 assuming “no smoke management” and “optimal smoke 

management” scenarios. An early model sensitivity run showed very little difference in modeled 

PM2.5 concentrations. Consequently, the fire emissions were not included in subsequent 

modeling runs (i.e., they were not in the Base K or Base M modeling inventories).

Future Year Emissions: Complete emission inventories were developed for several future years: 

Base K – 2009, 2012, and 2018, and Base M – 2009 and 2018. In addition, 2008 (Base K and 

Base M) and 2012 (Base M) proxy inventories were estimated based on the 2009 and 2018 

data. (Note, the EGU emissions for the Base M 2012 inventory were based on EPA’s IPM3.0 

modeling.)

Source sector emission summaries for the base years and future years are shown in Figure 48. 

Additional detail is provided in Tables 6a and 6b.

For on-road, and nonroad, the future year emissions were estimated by models (i.e., 

EMS/CONCEPT and NMIM, respectively). One adjustment was made to the 2009 and 2018 

motor vehicle emission files prepared by Environ with CONCEPT. To reflect newer 

transportation modeling conducted by CATS for the Chicago area, emissions were increased by 

9% in 2009 and 2018. The 2005 base year and adjusted 2009 and 2018 motor vehicle 

emissions are provided in Table 8.

For EGUs, future year emissions were based on IPM2.1.9 modeling completed by the RPOs in 

July 2005 Base K and IPM3.0 completed by EPA in February 2007 for Base M. Several CAIR 

scenarios were assumed:

Base K

1a: IPM2.1.9, with full trading and banking

1b: IPM2.1.9, with restricted trading (compliance with state-specific emission budgets) and full trading

1d: IPM2.1.9, with restricted trading (compliance with state-specific emission budgets)

Base M

5a: EPA’s IPM3.0 was assumed as the future year base for EGUs.

5b: EPA’s IPM3.0, with several “will do” adjustments identified by the States. These adjustments should 

reflect a legally binding commitment (e.g., signed contract, consent decree, or operating permit). 

5c: EPA’s IPM3.0, with several “may do” adjustments identified by the States. These adjustments reflect 

less rigorous criteria, but should still be some type of public reality (e.g., BART determination or press 

announcement).

For other sectors (area, MAR, and non-EGU point sources), the future year emissions for the 

LADCO States were derived by applying growth and control factors to the base year inventory. 

These factors were developed by a contractor (E.H. Pechan, 2005 and E.H. Pechan, 2007). 

For the non-LADCO States, future year emission files were based on data from other RPOs.

Growth factors were based initially on EGAS (version 5.0), and were subsequently modified (for 

select, priority categories) by examining emissions activity data. Due to a lack of information on 

future year conditions, the biogenic VOC and NOx emissions, and all Canadian emissions were 

assumed to remain the constant between the base year and future years.

A “base” control scenario was prepared for each future year based on the following “on the 

books” controls:

On-Highway Mobile Sources

• Federal Motor Vehicle Emission Control Program, low-sulfur gasoline and ultra-low sulfur diesel fuel

• Inspection - maintenance programs, including IL’s vehicle emissions tests (NE IL), IN’s vehicle 

emissions testing program (NW IN), OH’s E-check program (NE OH), and WI’s vehicle inspection 

program (SE WI) – note: a special emissions modeling run was done for the Cincinnati/Dayton area to 

reflect the removal of the state’s E-check program and inclusion of low RVP gasoline

• Reformulated gasoline, including in Chicago-Gary,-Lake County, IL,IN; and Milwaukee, Racine, WI

Off-Highway Mobile Sources

• Federal control programs incorporated into NONROAD model (e.g., nonroad diesel rule), plus the 

evaporative Large Spark Ignition and Recreational Vehicle standards

• Heavy-duty diesel (2007) engine standard/Low sulfur fuel

• Federal railroad/locomotive standards

• Federal commercial marine vessel engine standards

Area Sources (Base M only)

• Consumer solvents

• AIM coatings

• Aerosol coatings

• Portable fuel containers

Power Plants

• Title IV (Phases I and II)

• NOx SIP Call

• Clean Air Interstate Rule
60

Other Point Sources

• VOC 2-, 4-, 7-, and 10-year MACT standards

• Combustion turbine MACT

Other controls included in the modeling include: consent decrees (refineries, ethanol plants, and 

ALCOA)9, NOx RACT in Illinois and Ohio10, and BART for a few non-EGU sources in Indiana 

and Wisconsin.

For Base K, several additional control scenarios were considered:

Scenario 2 – “base” controls plus additional controls recommended in LADCO White 

Papers for stationary and mobile sources

Scenario 3 – Scenario 2 plus additional White Papers for stationary and mobile sources

Scenario 4 – “base” controls plus additional candidate control measures under

discussion by State Commissioners

Scenario 5 – “base” controls plus additional candidate control measures identified by the 

LADCO Project Team

3.7 Basecase Modeling Results

The purpose of the basecase modeling is to evaluate model performance (i.e., assess the 

model's ability to reproduce the observed concentrations). The model performance evaluation 

focused on the magnitude, spatial pattern, and temporal of modeled and measured 

concentrations. This exercise was intended to assess whether, and to what degree, confidence 

in the model is warranted (and to assess whether model improvements are necessary).

Model performance was assessed by comparing modeled and monitored concentrations. 

Graphical (e.g., side-by-side spatial plots, time series plots, and scatter plots) and statistical 

analyses were conducted. No rigid acceptance/rejection criteria were used for this study. 

Instead, the statistical guidelines recommended by EPA and other modeling studies (e.g., 

modeling by the other RPOs) were used to assess the reasonableness of the results. The 

model performance results presented here describe how well the model replicates observed 

ozone and PM2.5 concentrations after a series of iterative improvements to model inputs.

Ozone: Spatial plots are provided for high ozone periods in June 2002 and June 2005 (see 

Figures 49a and 49b). The plots show that the model is doing a reasonable job of reproducing 

the magnitude, day-to-day variation, and spatial pattern of ozone concentrations. There is a 

tendency, however, to underestimate the magnitude of regional ozone levels. This is more 

apparent with the 2002 modeling; the regional concentrations in the 2005 modeling agree better 

with observations due to model and inventory improvements.

 E.H. Pechan’s original control file included control factors for three sources in Wayne County, MI. 

These control factors were not applied in the regional-scale modeling to avoid double-counting with the 

State’s local-scale analysis for PM2.5 

10 NOx RACT in Wisconsin is included in the 2005 basecase (and EGU “will do” scenario). NOx RACT in 

Indiana was not included in the modeling inventory.

Standard model performance statistics were generated for the entire 12 km domain, and by day 

and by monitoring site. The domain-wide mean normalized bias for the 2005 base year is 

similar to that for the 2002 base year and is generally within 30% (see Figure 50). 

Figure 50. Mean bias for summer 2005 (Base M) and summer 2002 (Base K)

Station-average metrics (over the entire summer) are shown in Figure 51. The bias results 

further demonstrate the model’s tendency to underestimate absolute ozone concentrations.

A limited 4 km ozone analysis was performed by LADCO to address the effect of grid spacing. 

For this modeling, 4 km grids were placed over Lake Michigan and the Detroit-Cleveland area

(see Figure 52). Model inputs included 4 km emissions developed by LADCO (consistent with 

Base K/Round 4) and the 4 km meteorology developed by Alpine Geophysics. 

Figure 52. 4 km grids for Lake Michigan region and Detroit-Cleveland region

Hourly time series plots were prepared for several monitors (see Figure 53). The results are 

similar at 12 km and 4 km, with some site-by-site and day-by-day differences.

Figure 53. Ozone time series plots for 12 km and 4 km modeling (June 17-29, 2002)
65

An additional diagnostic analysis was performed to assess the response of the modeling system 

to changes in emissions (Baker and Kenski, 2007). Specifically, the 2002-to-2005 change in 

observed ozone concentrations was compared to the change in modeled ozone concentrations

based on the 95th percentile(and above) concentration values for each monitor. This analysis 

was also done with the inclusion of model performance criteria which eliminated poorly 

performing days (i.e., error > 35%). The results show good agreement in the modeled and 

monitored ozone concentration changes (e.g., ozone improves by about 9-10 ppb between 

2002 and 2005 according to the model and the measurements) – see Figure 54. This provides 

further support for using the model to develop ozone control strategies.

PM2.5: Time series plots of the monthly average mean bias and annual fractional bias for Base 

M and Base K are shown in Figure 55. As can be seen, Base M model performance for most 

species is fair (i.e., close to “no bias” throughout most of the year), with two main exceptions. 

First, the Base M and Base K results for organic carbon are poor, suggesting the need for more 

work on primary organic carbon emissions. Second, the Base M results for sulfate, while 

acceptable (i.e., bias values are within 35%), are not as good as the Base K results (e.g., 

noticeable underprediction during the summer months).

Base M (left column) and Base K (right column)

Two analyses were undertaken to understand sulfate model performance for 2005:

• Assess Meteorological Influences: The MM5 model performance evaluation showed that 

rainfall is over-predicted by MM5 over most of the domain during the summer months 

(LADCO, 2007c). Because CAMx does not explicitly use the rainfall output by MM5, this 

may or may not result in over-prediction sulfate wet deposition (and under-prediction of 

sulfate concentrations). A sensitivity run was performed with no wet deposition for July, 

August, and September. The resulting model performance (see green line in Figure 56)

showed a noticeable difference from the basecase (i.e., higher sulfate concentrations), 

and suggests that further evaluation of MM5 precipitation fields may be warranted.

• Assess Emissions Influences: The major contributor to sulfate concentrations in the 

region is SO2 emitted from EGUs. The basecase modeling inventory for EGUs is based 

on annual emissions, which were allocated to a typical weekday, Saturday, and Sunday 

by month using CEM-based temporal profiles. A sensitivity run was performed using 

day-specific emissions. The resulting model performance (see purple line in Figure 56)

showed little difference from the basecase.

Figure 56. Monthly sulfate bias for Base M (MRPO EGU) v. two sensitivity analyses (Note: positive 

values indicate over-prediction, negative values indicate under-prediction)

To assess the effect of the wet deposition issue on future year modeled values, another 

sensitivity run was conducted with no wet deposition in Quarters 2-3 for the base year 

(2005) and 2018. The resulting future year values were only slightly different from the 

current base strategy run. In general, the future year values (without wet deposition) 

were a little higher (+0.15 ug/m3 or less) in the Ohio Valley and a little lower (-.10 ug/m3

of less) in the Great Lakes region. This sensitivity run provides a bound for sulfate wet 

deposition issue in terms of the attainment test, given that having no wet deposition is 

unrealistic. The results suggest that even with an improved wet deposition treatment, 

the Base M strategy results are not expected to change very much.

Time series plots of daily sulfate, nitrate, elemental carbon, and organic carbon concentrations 

for three Midwestern locations are presented in Figures 57 (2002) and 58 (2005). These results 

are consistent with the model performance statistics (i.e., good agreement for sulfates and 

nitrates and poor agreement [large underprediction] for organic carbon).

In summary, model performance for ozone and PM2.5 is generally acceptable and can be 

characterized as follows:

Ozone

• Good agreement between modeled and monitored concentration for higher 

concentration levels (> 60 ppb) – i.e., bias within 30%

• Regional modeled concentrations appear to be underestimated in the 2002 base 

year, but show better agreement (with monitored data) in the 2005 base year due to 

model and inventory improvements.

• Day-to-day and hour-to-hour variation in and spatial patterns of modeled 

concentrations are consistent with monitored data

• Model accurately simulates the change in monitored ozone concentrations due to 

reductions in precursor emissions.

PM2.5

• Good agreement in the magnitude of fine particle mass, but some species are 

overestimated and some are underestimated (during periods of the year when it is 

important)

• Sulfates: good agreement in the 2002 base year, but underestimated in 

the summer in the 2005 base year due probably to meteorological factors

• Nitrates: slightly overestimated in the winter in the 2002 base year, but 

good agreement in the 2005 base year as a result of model and inventory 

improvements

• Organic Carbon: grossly underestimated in the 2002 and 2005 base 

years due likely to missing primary organic carbon emissions and, 

possibly, other factors (e.g., grid resolution and model chemistry).

• Temporal variation and spatial patterns of modeled concentrations are consistent 

with monitored data

Several observations should be noted on the implications of these model performance findings 

on the attainment modeling presented in the following section. First, it has been demonstrated 

that model performance overall is acceptable and, thus, the model can be used for air quality 

planning purposes. Second, consistent with EPA guidance, the model is used in a relative 

sense to project future year values. EPA suggests that this approach “should reduce some of 

the uncertainty attendant with using absolute model predictions alone” (EPA, 2007a). 

Furthermore, the attainment modeling is supplemented by additional information to provide a 

weight of evidence determination.
71

Section 4.0 Attainment Demonstration for Ozone and PM2./5

Air quality modeling and other information were used to determine whether existing (“on the 

books”) controls would be sufficient to provide for attainment of the NAAQS for ozone and PM2.5

and if not, then what additional emission reductions would be necessary for attainment. 

Traditionally, attainment demonstrations involved a “bright line” test in which a single modeled 

value was compared to the ambient standard. To provide a more robust assessment of 

expected future year air quality, EPA’s modeling guidelines call for consideration of 

supplemental information. This section summarizes the results of the primary (guideline) 

modeling analysis and a weight of evidence determination based on the modeling results and 

other supplemental analyses.

4.1 Future Year Modeling Results

The purpose of the future year modeling is to assess the effectiveness of existing and possible 

additional control programs. The model was used in a relative sense to project future year 

values, which are then compared to the standard to determine attainment/nonattainment. 

Specifically, the modeling test consists of the following steps:

(1) Calculate base year design values: For ozone and PM2.5, the base year design 

values were derived by averaging the three 3-year periods centered on the 

emissions base year:

2002 base year: 2000-2002, 2001-2003, and 2002-2004

2005 base year: 2003-2005, 2004-2006, and 2005-200711

(2) Estimate the expected change in air quality: For each grid cell, a relative 

reduction factor (RRF) is calculated by taking the ratio of the future year and 

baseline modeling results. 

(3) Calculate future year values: For each grid cell (with a monitor), the RRFs are 

multiplied by the base year design values to project the future year values

(4) Assess attainment: Future year values are compared to the NAAQS to assess 

attainment or nonattainment.

A comparison of the 2002 and 2005 base year design values for ozone and PM2.5 is provided in 

Figure 59. In general, the figure shows that the 2005 base year design values are much lower 

than the 2002 base year design values, especially for ozone.

 

11 A handful of source-oriented PM2.5 monitors in Illinois and Indiana were excluded from the annual 

attainment test, because these monitors are not to be used to judging attainment of the annual standard.

Ozone results are provided for those grid cells with ozone monitors. The RRF calculation 

considers all nearby grid cells (i.e., 3x3 for 12 km modeling) and a threshold of 85 ppb. (If there 

were less than 10 days above this value, then the threshold was lowered until either there were 

10 days or the threshold reached 70 ppb.) PM2.5 results are provided for those grid cells with 

FRM (PM2.5-mass) monitors. Spatial mapping was performed to extrapolate PM2.5-speciation 

data from STN and IMPROVE sites to FRM sites. RRF values for PM2.5 were derived as a 

function of quarter and chemical species.

Additional, hot-spot modeling will be performed by the states for certain PM2.5 nonattainment 

areas (e.g., Detroit, Cleveland, and Granite City) to address primary emissions from local point 

sources which may not be adequately accounted for by the regional grid modeling. This 

modeling will consist of Gaussian dispersion modeling (e.g., AERMOD) performed in 

accordance with EPA’s modeling guidance (see Section 5.3 of the April 2007 guidance 

document). Further analyses will need to be undertaken to determine how to best combine the 

regional modeling and the hot-spot modeling. This could mean some adjustment to the model 

results presented in this document to reflect better the regional component. 

The ozone and PM2.5 modeling results are provided in Appendix I for select monitors (high 

concentration sites) in the 5-state region for the following future years of interest: 2008 (ozone 

only), 2009, 2012, and 2018. (Note, RRF values for ozone, and for PM2.5 by season and 

chemical species are also included in Appendix I for key monitoring sites.) A summary of the 

modeling results is provided in Table 9 (ozone) and Table 10 (PM2.5), and spatial maps of the 

Base M future year concentrations are provided in Figures 60-62.

The modeling results above reflect the “base” controls identified in Section 3.6, with EGU 

emissions based on IPM modeling (i.e., Round 4 – IPM2.1.9, and Round 5 – IPM3.0). In 

addition, two sets of alternative future year EGU emissions were examined in Round 5. First, 

alternative control assumptions were provided for several facilities by the states (i.e., “will do” 

and “may do” scenarios). In general, these scenarios produced a small change in future year 

ozone and PM2.5 concentrations (i.e., about 0.1 ug/m

3

 for PM2.5 and 0.1-0.2 ppb for ozone). 

Second, EPA suggested adjustments to the 2010 IPM emissions to reflect 2009 conditions. The 

revised (2009) SO2 emissions represent a 5-6% increase in domainwide SO2 emissions. The 

increased SO2 emissions result in slightly greater annual average PM2.5 concentrations (on the 

order of 0.1 – 0.2 ug/m3), but do not produce any new residual nonattainment areas.

The limited 4 km ozone modeling (based on Base K) performed by LADCO included a future 

year analysis for 2009. The figure below shows the 2009 values with 12 km and 4 km grid 

spacing for the LADCO modeling and similar modeling conducted by a stakeholder group

(Midwest Ozone Group).

These results show that the 12 km and 4 km values are similar, with the most notable changes 

in northwestern Indiana and northeastern Illinois (e.g., 4 km values are as much as 4 ppb lower 

than 12 km values). The differences in the southern part of the Lake Michigan area are 

plausible, given the tight emissions gradient there (i.e., finer grid resolution appears to provide 

more appropriate representation). 

In light of these findings, 12 km grid spacing can continue to be used for ozone modeling, but 

the Base K/Round 4 results for northwestern Indiana/northeastern Illinois should be viewed with 

caution (i.e., probably 1 – 4 ppb too high).
81

In summary, the ozone modeling provides the following information for the nonattainment areas

Marginal Areas (2007 attainment date): No modeling was conducted for the 2006 SIP planning 

year. Rather, 2005 – 2007 air quality data are available to determine attainment.

Basic (Subpart 1) Areas (2009 attainment date): The modeling results for the 2008 SIP planning 

year show:

• Base K: all areas in attainment, except Cincinnati and Indianapolis

• Base M: all areas in attainment, except Holland (Allegan County) 

Moderate Areas (2010 attainment date): The modeling results for the 2009 SIP planning year 

show:

• Base K: all areas still in nonattainment

• Base M: all areas in attainment

The PM2.5 modeling results show:

• Base K: all areas in attainment, except for Chicago, Cincinnati, Cleveland, Detroit, 

Granite City (IL), Louisville, Portsmouth (OH), and Steubenville

• Base M: all areas in attainment, except for Cleveland, Detroit, and Granite City (IL)

With respect to the new lower 8-hour ozone standard, the modeling about 30 sites in 2012 and 

5 sites in 2018 with design values greater than 75 ppb. With respect to the new lower 24-hour 

PM2.5 standard, the modeling shows 13 sites in 2012 and 10 in 2018 with design values greater 

than 35 ug/m3.
82

4.2 Supplemental Analyses

EPA’s modeling guidelines recommend that attainment demonstrations consist of a primary 

(guideline) modeling analysis and supplemental analyses. Three basic types of supplemental 

analyses are recommended:

• additional modeling

• analyses of trends in ambient air quality and emissions, and

• observational models and diagnostic analyses

Furthermore, according to EPA’s guidelines, if the future year modeled values are “close” to the 

standard (i.e., 82 – 87 ppb for ozone and 14.5 – 15.5 ug/m3 for PM2.5), then the results of the 

primary modeling should be reviewed along with the supplemental information in a “weight of 

evidence” assessment of whether each area is likely to achieve timely attainment. 

A WOE determination for ozone and PM2.5 is provided in the following sections. Special 

attention is given to the following areas with future year modeled values that exceed or are 

“close” to the ambient standard (see Appendix I):

4.3 Weight-of-Evidence Determination for Ozone

The WOE determination for ozone consists of the primary modeling and other supplemental 

analyses (some of which were discussed in Section 2). A summary of this information is 

provided below.

Primary (Guideline) Modeling: The guideline modeling is presented in Section 4.1. Key findings 

from this modeling include:

• Base M regional modeling shows attainment by 2008 and 2009 at all sites, except 

Holland (MI), and attainment at all sites by 2012.

• Base K modeling results reflect generally higher future year values, and show more 

sites in nonattainment compared to the Base M modeling. The difference in the two 

modeling analyses is due mostly to lower base year design values in Base M.

• Base K and Base M modeling analyses are considered “SIP quality”, so the 

attainment demonstration for ozone should reflect a weight-of-evidence approach, 

with consideration of monitoring based information.

• Base M modeling also shows that the proposed lower 8-hour standard will not be 

met at many sites, even by 2018, with existing controls.

Additional Modeling: Four additional modeling analyses were considered: (1) re-examination of 

the primary modeling to estimate attainment probabilities, (2) remodeling with different 

assumptions, (3) an unmonitored area analysis, and (4) EPA’s latest regional ozone modeling. 

Each of these analyses is described below.
83

First, the primary modeling results (which were initially processed using EPA’s attainment test) 

were re-examined to estimate the probability of attaining the ozone standard (Lopez, 2007, and 

LADCO, 2008b). Seven estimates of future year ozone concentrations were calculated based 

on model-based RRFs and appropriate monitor-based concentrations for each year between 

2001 and 2007. RRF values for 2001, 2003, 2004, 2006, and 2007 were derived based on the 

2002 and 2005 modeling results. Monitor-based concentrations reflect 4th high values, design 

values, or average of three design values centered on the year in question. The probability of 

attainment was determined as the percentage of these seven estimates below the standard. 

The results indicate that sites in the Lake Michigan area (Chiwaukee, Sheboygan, Holland, 

Muskegon), Cleveland (Ashtabula), and St. Louis (W Alton) have a fairly low probability of 

attainment by 2009 (i.e., about 50% or less).

Second, the primary modeling analysis was redone with different types of assumptions for 

calculating base year design values (i.e., using the 3-year period centered on base year, and 

using the highest 3-year period that includes the base year), and for calculating RRFs (i.e.,

using all days with base year modeled value > 70 ppb, and using all days with base year 

modeled value > 85 ppb, with at least 10 days and “acceptable” model performance). The 

results for several high concentration sites are presented in Tables 13a and 13b for 2009. The 

different modeling assumptions produce eight estimates of future year ozone concentrations. 

The highest estimates are associated with base year design values representing the 3-year 

average for 2001-2003, and the lowest estimates are associated with base year design values 

representing the 3-year average 2004-2006. The different RRF approaches produce little 

change in future year ozone concentrations. This suggests that future year concentration 

estimates are most sensitive to the choice of the base year and the methodology used to derive 

the base year design values.

Third, EPA’s modeling guidelines recommend that an “unmonitored area analysis” be included 

as a supplemental analysis, particularly in nonattainment areas where the monitoring network 

just meets or minimally exceeds the size of the network required to report data to EPA’s Air 

Quality System. The purpose of this analysis is to identify areas where future year values are 

predicted to be greater than the NAAQS. 

Based on examination of the spatial plots in Figures 49a and 49b, the most notable areas of 

high modeled ozone concentrations are over the Great Lakes. Over-water monitoring, however, 

is not required by EPA12. A cursory analysis of unmonitored areas for ozone was performed by 

LADCO using an earlier version of the 2002 base year modeling (i.e, Base I) (Baker, 2005). 

Base year and future year “observed” values were derived for unmonitored grid cells using the 

absolute modeled concentrations (in all grid cells) and the observed values (in monitored grid 

cells). A spatial map of the estimated 2009 values is provided in Figure 64. As can be seen, 

there are very few (over land) grid cells where additional monitors may be desirable. This 

indicates that the current modeling analysis, which focuses on monitored locations, is 

addressing areas of high ozone throughout the region.

 

12 Air quality measurements over Lake Michigan were collected by LADCO previously to understand 

ozone transport in the area (see, for example, Figure 5). Due to cut-backs in USEPA funding, however, 

these measurements were discontinued in 2003.

Finally, EPA’s latest regional ozone modeling was considered as corroborative information. 

This modeling was performed as part of the June 2007 proposal to revise the ozone standard 

(EPA, 2007b). EPA applied the CMAQ model with 2001 meteorology to first estimate ozone 

levels in 2020 based on the current standard and national rules in effect or proposed (i.e., the 

baseline), and then to evaluate strategies for attaining a more stringent (70 ppb) primary 

standard. Baseline (2020) ozone levels were predicted to be below the current standard in 481 

of the 491 counties with ozone monitors. Of the 10 counties predicted to be above the 

standard, there is one county in the LADCO region (i.e., Kenosha County, WI at 86 ppb). This 

result is consistent with LADCO’s Base K modeling for 2018 (i.e., Kenosha County, WI at 86.7 

ppb), which is not surprising given that EPA’s modeling and LADCO’s Base K modeling have a

similar base year (2001 v. 2002).

Analysis of Trends: EPA’s modeling guidelines note that while air quality models are generally 

the most appropriate tools for assessing the expected impacts of a change in emissions, it may 

also be possible to extrapolate future trends based on measured historical trends of air quality 

and emissions. To do so, USEPA’s guidance suggests that ambient trends should first be 

normalized to account for year-to-year variations in meteorological conditions (EPA, 2002). 

Meterologically-adjusted 4th high 8-hour ozone concentrations were derived using the air quality 

– meteorological regression model developed by EPA (i.e., Cox method – see Section 2.1). 

The historical trend in these met-adjusted ozone concentrations were extrapolated to estimate 

future year ozone concentrations based on historical and projected trends in precursor 

emissions. Both VOC and NOx emissions affect ozone concentrations. Given that observationbased methods show that urban areas in the region are generally VOC-limited and rural areas 

in the region are NOx-limited (see Section 2.1), urban VOC emissions and regional NOx 

emissions are considered important. The trends in urban VOC and regional NOx emissions 

were calculated to produce appropriate weighting factors. 

The resulting 2009 and 2012 ozone values are provided in Figure 65, along with the primary 

and alternative modeling ozone values for key sites in the Lake Michigan, Cleveland, and 

Cincinnati areas. The results reflect a fairly wide scatter, but, on balance, the supplemental 

information is supportive of the primary modeling results (i.e., sites in the Lake Michigan area 

and Cleveland are expected to be close to the standard).

Observational Models and Diagnostic Analyses: The observation-based modeling (i.e., 

MAPPER) is presented in Section 3. The key findings from this modeling are that most urban 

areas are VOC-limited and rural areas are NOx-limited.

The primary diagnostic analysis is source apportionment modeling with CAMx to provide more 

quantitative information on source region (and source sector) impacts (Baker, 2007a). 

Specifically, the model estimated the impact of 18 geographic source regions (which are 

identified in Figure 66) and 6 source sectors (EGU point, non-EGU point, on-road, off-road, 

area, and biogenic sources) at ozone monitoring sites in the region.

 

Figure 66. Source regions (left) and key monitoring sites (right) for ozone modeling analysis

Modeling results for 2009 (Base M) and 2012 (Base K) are provided in Appendix II for several 

key monitoring sites. For each monitoring site, there are two graphs: one showing sector-level 

contributions, and one showing source region and sector-level contributions in terms of 

percentages. (Note, in the sector-level graph, the contributions from NOx emissions are shown 

in blue, and from VOC emissions in green.)

The sector-level results (see, for example, Figure 67) show that on-road and nonroad NOx 

emissions generally have the largest contributions at the key monitor locations (> 15% each). 

EGU and non-EGU NOx emissions are also important contributors (> 10% each). The source 

group contributions vary by receptor location due to emissions inventory differences.

The source region results (see, for example, Figure 68) show that while nearby areas generally 

have the highest impacts (e.g., the northeastern IL/northwestern IN/southeastern WI

nonattainment area contributes 25-35% to high sites in the Lake Michigan area, and Cleveland 

nonattainment counties contribute 20-25% to high sites in northeastern Ohio), there is an even 

larger regional impact (i.e., contribution from other states).

Figure 68. Source-region results for Holland (left) and Ashtabula (right) monitors – 2009 (Base M)

Summary: Air quality modeling and other supplemental analyses were performed to estimate 

future year ozone concentrations. Based on this information, the following general conclusions 

can be made:

• Existing (“on the books”) controls are expected to produce significant 

improvement in ozone air quality.

• The choice of the base year affects the future year model projections. A key 

difference between the base years of 2002 and 2005 is meteorology. As noted 

above, 2002 was more ozone conducive than 2005. The choice of which base 

year to use as the basis for the SIP is a policy decision (i.e., how much safeguard 

to incorporate).

• Most sites are expected to meet the current 8-hour standard by the applicable 

attainment date, except, for sites in western Michigan and, possibly, in eastern 

Wisconsin and northeastern Ohio.

• Current monitoring data show significant nonattainment in these areas (e.g., 

peak design values on the order of 90 – 93 ppb). It is not clear whether sufficient 

emission reductions will occur in the next couple of years to provide for 

attainment.

• Attainment by the applicable attainment date is dependent on actual future year 

meteorology (e.g., if the weather conditions are consistent with [or less severe 

than] 2005, then attainment is likely) and actual future year emissions (e.g., if the 

emission reductions associated with the existing controls are achieved, then 

attainment is likely). On the other hand, if either of these conditions is not met, 

then attainment may be less likely.

4.3 Weight-of-Evidence Determination for PM2.5

The WOE determination for PM2.5 consists of the primary modeling and other supplemental 

analyses. A summary of this information is provided below.

Primary (Guideline) Modeling: The results of the guideline modeling are presented in Section 

4.1. Key findings from this modeling include:

• Base M regional modeling shows attainment by 2009 at all sites, except Detroit, 

Cleveland, and Granite City, and attainment at all sites by 2012, except for Detroit 

and Granite City.

The regional modeling for PM2.5 does not reflect any air quality benefit expected 

from local controls. States are conducting local-scale analyses and will use these 

results, in conjunction with the regional-scale modeling, to support their attainment 

demonstrations for PM2.5

• Base K modeling results reflect generally higher future year values, and show more 

sites in nonattainment in 2009 and 2012 compared to the Base M modeling. The 

difference in the two modeling analyses is due mostly to lower base year design 

values in Base M.

• Base K and Base M modeling analyses are considered “SIP quality”, so the 

attainment demonstration for PM2.5 should reflect a weight-of-evidence approach, 

with consideration of monitoring based information.

• Base M modeling also shows that the new PM2.5 24-hour standard will not be met at 

many sites, even by 2018, with existing controls.

Additional Modeling: EPA’s latest regional PM2.5 modeling was considered as corroborative 

information. This modeling was performed as part of the September 2006 revision to the PM2.5

standard (USEPA, 2006). EPA applied the CMAQ model with 2001 meteorology to estimate 

PM2.5 levels in 2015 and 2020 first with national rules in effect or proposed, and then with 

additional controls to attain the current standard (15 ug/m3 annual/65 ug/m3 daily). Additional 

analyses were performed to evaluate strategies for attaining more stringent standards in 2020 

(15/35, and 14/35). Baseline (2015) PM2.5 levels were predicted to be above the current 

standard in four counties in the LADCO region: Madison County, IL at 15.2 ug/m3, Wayne 

County, MI at 17.4, Cuyahoga County, OH at 15.4, and Scioto County, OH at 15.6. These 

results are consistent with LADCO’s Base K modeling for 2012/2018, which is not surprising 

given that EPA’s modeling and LADCO’s Base K modeling have a similar base year (2001 v. 

2002).

Observational Models and Diagnostic Analyses: The observation-based modeling (i.e., 

application of thermodynamic equilibrium models) is presented in Section 3. The key findings 

from this modeling are that PM2.5 mass is sensitive to reductions in sulfate, nitric acid, and 

ammonia concentrations. Even though sulfate reductions cause more ammonia to be available 

to form ammonium nitrate (PM-nitrate increases slightly when sulfate is reduced), this increase 

is generally offset by the sulfate reductions, such that PM2.5 mass decreases. Under conditions 

with lower sulfate levels (i.e., proxy of future year conditions), PM2.5 is more sensitive to 

reductions in nitric acid compared to reductions in ammonia.
91

The primary diagnostic analysis is source apportionment modeling with CAMx to provide more 

quantitative information on source region (and source sector) impacts (Baker, 2007b). 

Specifically, the model estimated the impact of 18 geographic source regions (which are 

identified in Figure 69) and 6 source sectors (EGU point, non-EGU point, on-road, off-road, 

area, and biogenic sources) at PM2.5 monitoring sites in the region.

 

Figure 69. Source regions (left) and key monitoring sites (right) for PM2.5 modeling analysis

Modeling results for 2012 (Base K) and 2018 (Base M) are provided in Appendix III for several 

key monitoring sites. For each monitoring site, there are two graphs: one showing sector-level 

contributions, and one showing source region and sector-level contributions in terms of absolute 

modeled values.

The sector-level results (see, for example, Figure 70) show that EGU sulfate, non-EGU-sulfate, 

and area organic carbon emissions generally have the largest contributions at the key monitor 

locations (> 15% each). Ammonia emissions are also important contributors (> 10%). The 

source group contributions vary by receptor location due to emissions inventory differences.

The source region results (see, for example, Figure 71) show that while nearby areas generally 

have the highest impacts (e.g., Detroit nonattainment counties contribute 40% to high sites in 

southeastern Michigan, and Cleveland nonattainment counties contribute 35% to high sites in 

northeastern Ohio), there is an even larger regional impact (i.e., contribution from other states).

Figure 71. Source-region results for Detroit (left) and Cleveland (right) monitors – 2018 (Base M)

Summary: Air quality modeling and other supplemental analyses were performed to estimate 

future year PM2.5 concentrations. Based on this information, the following general conclusions 

can be made:

• Existing (“on the books”) controls are expected to produce significant 

improvement in PM2.5 air quality.

• The choice of the base year affects the future year model projections. It is not 

clear how much of this is attributable to differences in meteorology, because, as 

noted in Section 3, PM2.5 concentrations are not as strongly influenced by 

meteorology as ozone.

• Most sites are expected to meet the current PM2.5 standard by the applicable 

attainment date, except for sites in Detroit, Cleveland, and Granite City.

• Current monitoring data show significant nonattainment in these areas (e.g., 

peak design values on the order of 16 – 17 ug/m3). It is not clear whether 

sufficient emission reductions will occur in the next couple of years to provide for 

attainment. States are conducting local-scale analyses for Detroit, Cleveland, 

and Granite City, in particular, to identify appropriate additional local controls.

• Attainment by the applicable attainment date is dependent (possibly) on actual 

future year meteorology and (more likely) on actual future year emissions (e.g., if 

the emission reductions associated with the “on the books” controls are 

achieved, then attainment is likely). On the other hand, if either of these 

conditions is not met (especially, with respect to emissions), then attainment may 

be less likely.

Section 5. Reasonable Progress Assessment for Regional Haze

Air quality modeling and other information were used to assess the improvement in visibility that 

would be provided by existing (“on the books”) controls and possible additional control 

programs. In determining reasonable progress for regional haze, Section 169A of the Clean Air 

Act and EPA’s visibility rule requires states to consider five factors:

• costs of compliance

• time necessary for compliance

• energy and non-air quality environmental impacts of compliance

• remaining useful life of any existing source subject to such requirements

• uniform rate of visibility improvement needed to attain natural visibility conditions 

by 2064

The uniform rate of visibility improvement requirement can be depicted graphically in the form of 

a “glide path” (see Figure 72).

Figure 72. Visibility “glide paths” for northern Class I areas (units: deciviews)

5.1 Class I Areas Impacted

EPA’s visibility rule requires a state to “address regional haze in each mandatory Class I 

Federal area located within the State and in each mandatory Class I Federal area located 

outside the State which may be affected by emissions from within the State.” (40 CFR Part 

51.308(d)) To meet this requirement, technical analyses conducted by the RPOs were 

consulted to obtain information on areas of influence and culpability for Class I areas in the 

eastern U.S. (MRPO, 2007). A summary of this information is provided in Table 1 (MRPO, 

2007). The table shows that every LADCO State impacts multiple Class I areas in the eastern 

U.S.

5.2 Future Year Modeling Results

For regional haze, the calculation of future year conditions assumed: 

• baseline concentrations based on 2000-2004 IMPROVE data, with updated 

(subsitituted) data for Mingo, Boundary Waters, Voyageurs, Isle Royale, and 

Seney (see Section 2.3);

• use of the new IMPROVE light extinction equation; and

• use of EPA default values for natural conditions, based on the new IMPROVE 

light extinction equation.

The uniform rate of visibility improvement values for the 2018 planning year were derived (for 

the 20% worst visibility days) based on a straight line between baseline concentration value 

(plotted in the year 2004 -- end year of the 5-year baseline period) and natural condition value 

(plotted in the year 2064 -- date for achieving natural conditions). Plots of these “glide paths” 

with the Base M modeling results are presented in Figure 73 for Class I areas in the eastern 

U.S. A tabular summary of measured baseline and modeled future year deciview values for 

these Class I areas are provided in Table 15 (2002 base year) and Table 16 (2005 base year)13.

The haze results show that several Class I areas in the eastern U.S. are expected to be greater 

than (less improved than) the uniform rate of visibility improvement values (in 2018), including 

those in northern Michigan and several in the northeastern U.S. Many other Class I areas in the 

eastern U.S. are expected to be less than (more improved than) the uniform rate of visibility 

improvement values (in 2018). As noted above, states should consider these results, along with 

information on the other four factors, in setting reasonable progress goals. 

An assessment of the five factors was performed for LADCO and the State of Minnesota by a 

contractor (EC/R, 2007). Specifically, ECR examined reductions in SO2 and NOx emissions 

from EGUs and industrial, commercial and institutional (ICI) boilers; NOx emissions from mobile 

sources and reciprocating engines and turbines; and ammonia emissions from agricultural 

operations. The impacts of “on the books” controls were also examined to provide a frame of 

reference for assessing the impacts of the additional control measures.

The results of ECR’s analysis of the five factors are summarized below:

Factor 1 (Cost of Compliance): The average cost effectiveness values (in terms of $M 

per ton) are provided in Table 16. For comparison, cost-effectiveness estimates 

previously provided for “on the books” controls include:

CAIR SO2: $700 - $1,200, NOx: $1,400 – $2.600 ($/T)

BART SO2: $300 - $963, NOx: $248 - $1,770

MACT SO2: $1,500, NOx: $7,600

Most of the cost-effectiveness values for the additional controls are within the range of 

cost-effectiveness values for “on the books” controls.

Factor 2 (Time Necessary for Compliance): All of the control measures can be 

implemented by 2018. Thus, this factor can be easily addressed.

Factor 3 (Energy and Non-Air Quality Environmental Impacts): The energy and other 

environmental impacts are believed to be manageable. For example, the increased 

energy demand from add-on control equipment is less than 1% of the total electricity 

and steam production in the region, and solid waste disposal and wastewater treatment 

costs are less than 5% of the total operating costs of the pollution control equipment. It 

should also be noted that the SO2 and NOx controls would have beneficial 

environmental impacts (e.g., reduced acid deposition and nitrogen deposition).

Factor 4 (Remaining Useful Life): The additional control measures are intended to be 

market-based strategies applied over a broad geographic region. It is not expected that 

the control requirements will be applied to units that will be retired prior to the 

amortization period for the control equipment. Thus, this factor can be easily addressed.

Factor 5 (Visibility Impacts): The estimated incremental improvement in 2018 visibility 

levels for the additional measures is shown in Figure 74, along with the costeffectiveness expressed in $M per deciview improvement). These results show that 

although EGU and ICI boiler controls have higher cost-per-deciview values (compared 

to some of the other measures), their visibility impacts are larger.

5.3 Weight-of-Evidence Determination for Haze

The WOE determination for haze consists of the primary modeling and other supplemental 

analyses. A summary of this information is provided below.

Primary (Guideline) Modeling: The results of the guideline modeling are presented in Section 

4.1. Key findings from this modeling include:

• Base M modeling results show that the northern Minnesota Class I areas are close 

to the glide path, whereas the northern Michigan Class I areas are above the glide 

path in 2018. Other sites in the eastern U.S. are close to (or below) the glide path, 

except for Mingo (MO), Brigantine (NJ), and Acadia (ME).

• Base K modeling results show that the northern Minnesota and northern Michigan 

Class I areas are above the glide path in 2018. Other sites in the eastern U.S. are 

close to (or below) the glide path. 

• The difference in the two modeling analyses is due mostly to differences in future 

year emission projections, especially for EGUs (e.g., use of IPM2.1.9 v. IPM3.0).

• Base K and Base M modeling analyses are considered “SIP quality”, so the 

attainment demonstration for haze should reflect a weight-of-evidence approach, 

with consideration of monitoring based information.

Additional Modeling: Two additional modeling analyses were considered: (1) the primary 

modeling redone with different baseline values, and (2) modeling by the State of Minnesota 

which looked at different receptor locations in the northern Class I areas (MPCA, 2008). Each 

of these analyses is described below.

First, the primary modeling analysis (Base M) was revised using an alternative baseline value. 

Specifically, the data for the period 2000-2005 were used to calculate the baseline, given that 

the Base M modeling reflects a 2005 base year. The results of this alternative analysis (see 

Table 18) are generally consistent with the primary modeling (see Table 16).

Second, Minnesota’s modeling reflects a 2002 base year and much of the data developed by 

LADCO for its modeling. (Note, Minnesota conducted modeling for LADCO’s domain at 36 km, 

and for a statewide domain at 12 km.) The purpose of the 12 km modeling was to address local 

scale impacts on the northern Class I areas at several locations, not just the location of the 

IMPROVE monitor. Results for the Boundary Waters on the 20% worst days range from 18.3 –

19.0 dv, with an average value of 18.7 dv, which is consistent with Minnesota’s 36 km modeling 

results at the IMPROVE monitor. This variability in visibility levels should be kept in mind when 

reviewing the values presented in Tables 15, 16, and 18, which reflect results at the IMPROVE 

monitor locations.

Observational Models and Diagnostic Analyses: The observation-based modeling (i.e., 

application of thermodynamic equilibrium models) is presented in Section 3. The key findings 

from this modeling are that PM2.5 mass is sensitive to reductions in sulfate, nitric acid, and 

ammonia concentrations. Even though sulfate reductions cause more ammonia to be available 

to form ammonium nitrate (PM-nitrate increases slightly when sulfate is reduced), this increase 

is generally offset by the sulfate reductions, such that PM2.5 mass decreases and visibility 

improves. Under conditions with lower sulfate levels (i.e., proxy of future year conditions), PM2.5

is more sensitive to reductions in nitric acid compared to reductions in ammonia.

As discussed in Section 2, thermodynamic equilibrium modeling based on data collected at 

Seney indicates that PM2.5 there is most sensitive to reductions in sulfate, but also responsive to 

reductions in nitric acid (Blanchard, 2004). An analysis using data from the Midwest ammonia 

monitoring network for a site in Minnesota (i.e., Great River Bluffs, which is the closest ammonia 

monitoring site to the northern Class I areas) suggested that reductions in sulfate, nitric acid, 

and ammonia concentrations will lower PM2.5 concentrations and improve visibility levels in the 

northern Class I areas.

Trajectory analyses for the 20% worst visibility days for the four northern Class I areas are 

provided in Figure 75. (Note, this figure is similar to Figure 34, but the trajectory results for each 

Class I area are displayed separately here.) The orange areas are where the air is most likely 

to come from, and the green areas are where the air is least likely to come from. Darker 

shading represents higher frequency. As can be seen, bad air days are generally associated 

with transport from regions located to the south, and good air days with transport from Canada.

The primary diagnostic analysis is source apportionment modeling with CAMx to provide more 

quantitative information on source region (and source sector) impacts (Baker, 2007b). 

Specifically, the CAMx model was applied to provide source contribution information. 

Specifically, the model estimated the impact of 18 geographic source regions (which are 

identified in Figure 76) and 6 source se ctors (EGU point, non-EGU point, on-road, off-road, 

area, and ammonia sources) at visibility/haze monitoring sites in the eastern U.S.
108

 

Figure 76. Source regions (left) and key monitoring sites (right) for haze modeling analysis

Modeling results for 2018 (Base K and Base M) are provided in Appendix IV for several key 

monitoring sites (Class I areas). For each monitoring site, there are two graphs: one showing 

sector-level contributions, and one showing source region and sector-level contributions in 

terms of absolute modeled values.

The sector-level results (see, for example, Figure 77) show that EGU sulfate, non-EGU-sulfate, 

and ammonia emissions generally have the largest contributions at the key monitor locations. 

The source group contributions vary by receptor location due to emissions inventory differences. 

Figure 77. Source-sector results for Seney (left) and Boundary Waters (right) – 2018 (Base M)

The source region results (see, for example, Figure 78) show that emissions from a number of 

nearby states contribute to regional haze levels.

Table 19 provides a summary of the estimated state-level culpabilities based on the LADCO 

back trajectory analyses and the PSAT analyses for 2018.

Summary: Air quality modeling and other supplemental analyses were performed to estimate 

future year visibility levels. Based on this information, the following general conclusions can be 

made:

• Existing (“on the books”) controls are expected to improve visibility levels in the 

northern Class I areas.

• Visibility levels in a few Class I areas in the eastern U.S. are expected to be 

greater than (less improved than) the uniform rate of visibility improvement 

values in 2018, including those in northern Michigan and some in the 

northeastern U.S. 

• Visibility levels in many other Class I areas in the eastern U.S. are expected to 

be less than (more improved than) the uniform rate of visibility improvement 

values in 2018.

Section 6. Summary

To support the development of SIPs for ozone, PM2.5, and regional haze in the States of Illinois, 

Indiana, Michigan, Ohio, and Wisconsin, technical analyses were conducted by LADCO, its 

member states, and various contractors. The analyses include preparation of regional 

emissions inventories and meteorological modeling data for two base years, evaluation and 

application of regional chemical transport models, and review of ambient monitoring data. 

Analyses of monitoring data were conducted to produce a conceptual model, which is a

qualitative summary of the physical, chemical, and meteorological processes that control the 

formation and distribution of pollutants in a given region. Key findings of the analyses include:

Ozone

• Current monitoring data show about 20 sites in violation of the 8-hour ozone 

standard of 85 ppb. Historical ozone data show a steady downward trend over the 

past 15 years, especially since 2001-2003, due likely to federal and state emission 

control programs.

• Ozone concentrations are strongly influenced by meteorological conditions, with 

more high ozone days and higher ozone levels during summers with above normal 

temperatures.

• Inter- and intra-regional transport of ozone and ozone precursors affects many 

portions of the five states, and is the principal cause of nonattainment in some areas 

far from population or industrial centers

PM2.5

• Current monitoring data show 30 sites in violation of the annual PM2.5 standard of 15 

ug/m3. Nonattainment sites are characterized by an elevated regional background 

(about 12 – 14 ug/m3) and a significant local (urban) increment (about 2 – 3 ug/m3). 

Historical PM2.5 data show a slight downward trend since deployment of the PM2.5

monitoring network in 1999.

• PM2.5 concentrations are also influenced by meteorology, but the relationship is more 

complex and less well understood compared to ozone.

• On an annual average basis, PM2.5 chemical composition consists of mostly sulfate, 

nitrate, and organic carbon in similar proportions.

Haze

• Current monitoring data show visibility levels in the Class I areas in northern 

Michigan are on the order of 22 – 24 deciviews. The goal of EPA’s visibility program 

is to achieve natural conditions, which is on the order of 12 deciviews for these 

Class I areas, by the year 2064.

• Visibility impairment is dominated by sulfate and nitrate.

Air quality models were applied to support the regional planning efforts. Two base years were 

used in the modeling analyses: 2002 and 2005. EPA’s modeling guidance recommends using 
112

2002 as the baseline inventory year, but also allows for use of an alternative baseline inventory 

year, especially a more recent year. Initially, LADCO conducted modeling with a 2002 base 

year (i.e., Base K modeling, which was completed in 2006). A decision was subsequently made 

to conduct modeling with a 2005 base year (i.e., Base M, which was completed in 2007). 

Statistical analyses showed that 2002 and 2005 both had above normal ozone-conducive 

conditions, although 2002 was more severe compared to 2005. Examination of multiple base 

years provides for a more complete technical assessment. Both sets of model runs are 

discussed in this document. 

Basecase modeling was conducted to evaluate model performance (i.e., assess the model's 

ability to reproduce the observed concentrations). This exercise was intended to assess 

whether, and to degree, confidence in the model is warranted (and to assess whether model 

improvements are necessary). Model performance for ozone and PM2.5 was generally

acceptable and can be characterized as follows:

Ozone

• Good agreement between modeled and monitored concentration for higher 

concentration levels (> 60 ppb) – i.e., bias within 30%

• Regional modeled concentrations appear to be underestimated in the 2002 base 

year, but show better agreement (with monitored data) in the 2005 base year due to 

model and inventory improvements.

• Day-to-day and hour-to-hour variation in and spatial patterns of modeled 

concentrations are consistent with monitored data

• Model accurately simulates the change in monitored ozone concentrations due to 

reductions in precursor emissions.

PM2.5

• Good agreement in the magnitude of fine particle mass, but some species are 

overestimated and some are underestimated

• Sulfates: good agreement in the 2002 base year, but underestimated in 

the summer in the 2005 base year due probably to meteorological factors

• Nitrates: slightly overestimated in the winter in the 2002 base year, but 

good agreement in the 2005 base year as a result of model and inventory 

improvements

• Organic Carbon: grossly underestimated in the 2002 and 2005 base 

years due likely to missing primary organic carbon emissions

• Temporal variation and spatial patterns of modeled concentrations are consistent 

with monitored data

Future year strategy modeling was conducted to determine whether existing (“on the books”) 

controls would be sufficient to provide for attainment of the standards for ozone and PM2.5 and if 

not, then what additional emission reductions would be necessary for attainment. Traditionally, 

attainment demonstrations involved a “bright line” test in which a single modeled value (based 

on EPA guidance) was compared to the ambient standard. To provide a more robust 

assessment of expected future year air quality, other information was considered. Furthermore, 

according to EPA’s modeling guidance, if the future year modeled values are “close” to the 
113

standard (i.e., 82 – 87 ppb for ozone and 14.5 – 15.5 ug/m3 for PM2.5 ), then the results of the 

primary modeling should be reviewed along with the supplemental information in a “weight of 

evidence” (WOE) assessment of whether each area is likely to achieve timely attainment. Key 

findings of the WOE determination include:

• Existing controls are expected to produce significant improvement in ozone and 

PM2.5 concentrations and visibility levels.

• The choice of the base year affects the future year model projections. A key 

difference between the base years of 2002 and 2005 is meteorology. 2002 was 

more ozone conducive than 2005. The choice of which base year to use as the 

basis for the SIP is a policy decision (i.e., how much safeguard to incorporate).

• Most sites are expected to meet the current 8-hour standard by the applicable 

attainment date, except for sites in western Michigan and, possibly, in eastern 

Wisconsin and northeastern Ohio.

• Most sites are expected to meet the current PM2.5 standard by the applicable 

attainment date, except for sites in Detroit, Cleveland, and Granite City.

The regional modeling for PM2.5 does not reflect air quality benefits expected 

from local controls. States are conducting local-scale analyses and will use

these results, in conjunction with the regional-scale modeling, to support their 

attainment demonstrations for PM2.5.

• These findings of residual nonattainment for ozone and PM2.5 are supported by 

current (2005 – 2007) monitoring data which show significant nonattainment in 

the region (e.g., peak ozone design values on the order of 90 – 93 ppb, and peak 

PM2.5 design values on the order of 16 - 17 ug/m3). It is unlikely that sufficient 

emission reductions will occur in the next few of years to provide for attainment at 

all sites.

• Attainment at most sites by the applicable attainment date is dependent on actual 

future year meteorology (e.g., if the weather conditions are consistent with [or 

less severe than] 2005, then attainment is likely) and actual future year 

emissions (e.g., if the emission reductions associated with the existing controls 

are achieved, then attainment is likely). If either of these conditions is not met, 

then attainment may be less likely.

• The new PM2.5 24-hour standard and the new lower ozone standard will not be 

met at several sites, even by 2018, with existing controls.

• Visibility levels in a few Class I areas in the eastern U.S. are expected to be 

greater than (less improved than) the uniform rate of visibility improvement 

values in 2018 based on existing controls, including those in northern Michigan 

and some in the northeastern U.S. Visibility levels in many other Class I areas in 

the eastern U.S. are expected to be less than (more improved than) the uniform 

rate of visibility improvement values in 2018.

Regional Air Quality Analyses for Ozone, PM2.5, and Regional Haze: 

Final Technical Support Document (Supplement), September 12, 2008

The purpose of this paper is to summarize a new modeling analysis performed by the Lake 

Michigan Air Directors Consortium (LADCO) to address the effect of the recent court decision 

vacating EPA’s Clean Air Interstate Rule (CAIR). This new modeling is intended to supplement 

the LADCO Technical Support Document (“Regional Air Quality Analyses for Ozone, PM2.5, 

and Regional Haze: Final Technical Support Document”, April 25, 2008), which summarizes the 

air quality analyses conducted by LADCO and its contractors to support the development of 

State Implementation Plans for ozone, PM2.5, and regional haze in the States of Illinois, 

Indiana, Michigan, Ohio, and Wisconsin.

Compared to the previous LADCO modeling (Round 5.1), the new modeling shows similar 

results for ozone, but much more nonattainment for PM2.5 and higher visibility levels for 

regional haze. Specifically, the new modeling shows:

Ozone: Attainment of the 0.08 ppm standard by 2009 everywhere in the region, except 

Holland, MI, and nonattainment of the 0.075 ppm standard through at least 2018.

PM2.5: Widespread nonattainment of annual (15 ug/m3) and daily (35 ug/m3) standards.

Haze: Higher visibility levels on the 20% worst visibility days in 2018 in Class I areas in 

the eastern U.S., resulting in most areas being above the glide path.

Background: On July 11, 2008, the U.S. Court of Appeals for D.C. Circuit vacated EPA’s CAIR 

rule (cite). The reductions in NOx and SO2 emissions associated with this rule were a key part 

of the LADCO States’ attainment demonstrations for ozone and PM2.5 and the reasonable 

progress determinations for regional haze. LADCO’s previous modeling (Round 5.1) relied on 

EGU emission projections from EPA’s IPM3.0 analysis, which assumed implementation of 

Phases I and II of CAIR. For this new modeling, alternative EGU emission projections were 

developed, which did not rely on CAIR (or IPM).

Model Set-Up: The new modeling was performed consistent with LADCO’s previous modeling 

(Round 5.1):

Model Version: CAMx v4.50beta_deposition

Future Years: 2009, 2012, 2018

Runs: (a) Ozone: Summer 2005 meteorology with 12 km grids

(b) PM2.5 and haze: Full year 2005 meteorology with 36 km grids

Emission Scenarios: The new modeling assumed the same set of “on the books” controls as 

in LADCO’s previous modeling (Round 5.1) for all sectors, except EGUs. In light of the CAIR 

decision, three new EGU scenarios were prepared:
2

Scenario A: 2007 CEM-based emissions were projected for all states in the modeling domain 

based on EIA growth rates by state (NERC region) and fuel type. The assumed growth rates for 

the Midwest States were: MAIN (IL, IA, MO, WI): 8.8% (2007-2018); ECAR (IN, KY, MI, OH): 

13.5% (2007-2018); and MAPP (MN): 15.1% (2007-2018). No control was applied. The annual 

emissions were temporalized based on profiles derived from 2004-2006 CEM data. (Note, these 

are the same temporal profiles used in Round 5.1.)

Scenario B. Scenario A emissions for the LADCO States and select neighboring states (e.g., 

MN, IA, MO, KY, TN, and WV) were adjusted by applying legally enforceable controls (i.e., 

emission reductions required by a Consent Decree, state rule, or permit). Only those legally 

enforceable controls identified (and justified) by the States were applied. The States also 

supplied the appropriate control factors. A table summarizing the Scenario B controls is provided 

in Appendix I.

Scenario C. For the years 2009 and 2012, Scenario A emissions for all states were adjusted by 

applying all planned SO2 and NOx controls based on the July 10 CAMD list (i.e., 90% reduction 

for scrubbers, 95% reduction for SCRs). Because the July 10 CAMD list only includes controls 

generally out to 2011, additional SO2 and NOx controls for the year 2018 were assumed for all 

BART-eligible EGUs in the five LADCO State plus MN, IA, MO, KY, TN, and MO list (i.e., 90% 

reduction for scrubbers, 95% reduction for SCRs).

1

 All Scenario B controls were included in 

Scenario C. A table summarizing the Scenario C controls is provided in Appendix II.

Table 1 and Figure 1 provide a summary of the 5-state regional NOx and SO2 emissions for 

each scenario and future year. (Note, the CAIR emissions included here are based on EPA’s 

IPM3.0 modeling.) Several comments on the emissions should be noted:

Summer NOx

• There is llittle difference between the three alternative scenarios and CAIR. This 

suggests that summer ozone concentrations for the alternative scenarios are 

likely to be similar to those predicted with CAIR (i.e., Round 5.1).

Annual NOx:

• There is a significant change in emissions between scenarios, mostly during the 

non-summer months.

• Scenario B reflects application of NOx controls in several states (e.g., IL,OH,WI).

• Because there are relatively few SCRs (in the LADCO States) on the CAMD list, 

Scenario C results in only a small emissions decrease compared to Scenario B.

• Assumed BART controls result in a significant emissions decrease.

Annual SO2

• There is a significant change in emissions between scenarios.

• Scenario B reflects application of SO2 controls in several states (e.g., IL,OH,WI).

• Because there are several FGDs (in the LADCO States) on the CAMD list, 

Scenario C results in a large emissions decrease compared to Scenario B.

• Assumed BART controls result in a significant emissions decrease (i.e., even 

lower emissions than the IPM-estimated CAIR emissions).

 

1

 A subsequent analysis was conducted with the following inventory changes: (a) 95% reduction for 

scrubbers, 90% redcuction for SCRs (consistent with EPA’s default assumptions for IPM), and (b)

revisions provided for a few plants in Indiana and Minnesota. The changes resulted in a relatively small 

difference in the regioinal NOx and SO2 emissions (e.g., about a 2% NOx increase and about a 1-2% 

decrease in SO2). To assess the impact of the changes, PM2.5 modleing was conducted with the new 

Scenario B and Scenario C emissions for 2012. The modeling showed little change in the predicted 

PM2.5 concentrations.

Modeling Results: Several tables summarizing the modeling results are provided:

Table 2 - future year ozone and PM2.5 concentrations for key monitors in the 

 LADCO region

Table 3 - number of monitoring sites greater than the National Ambient Air Quality 

 Standards (NNAQS)

Table 4 – visibility levels for Class I areas in the eastern U.S. 

Note, given that Scenario B and BART controls were only applied in an 11-state Midwest 

region, the validity of the results for other Class I areas in the eastern U.S. may be 

questionable. The Scenario C controls, on the other hand, cover all states and are, thus, 

likely valid in other Class I areas.

Spatial plots of the future year ozone and PM2.5 concentrations are provided in Figures 2 – 4. 

Based on these results, the following key findings should be noted:

Ozone 

• There is little change from the previous LADCO modeling (Round 5.1 with CAIR)

• The modeling shows attainment of the 0.08 ppm (85 ppb) standard by 2009, 

except Holland. (Note, Holland does meet this standard by 2012.)

• The modeling shows nonattainment of the 0.075 ppm (75 ppb) standard through 

2018.

PM2.5 - Annual

• There is a significant change from the previous LADCO modeling (Round 5.1 

with CAIR)

• The modeling shows extensive nonattainment of the annual standard.

PM2.5 - Daily 

• There is a significant change from the previous LADCO modeling (Round 5.1 

with CAIR)

• The modeling shows extensive nonattainment of the daily standard.

Haze 

• There is a significant change from the previous LADCO modeling (Round 5.1 

with CAIR)

• The modeling shows higher visibility levels in 2018 for the 20% worst visibility 

days (average about 0.5 deciviews for the northern Class I areas). The resulting 

visibility levels in the northern Class I areas (except Voyageurs) are above the 

glide path.

Base M Strategy Modeling: Emissions (Revised)

The purpose of this document is to summarize the emission estimates prepared for LADCO’s

latest (Base M) 2005 base year and 2008, 2009, 2012, and 2018 future year modeling. Base 

year emissions by state and source sector for Base K (2002) and Base M (2005) are compared 

in Figure 1. A more detailed state and source sector summary is provided in Attachment 1.

Base Year Emissions

In mid-2006, LADCO completed modeling analyses for a 2002 base year and several future 

year control strategies (LADCO, 2006a and LADCO, 2006b). Following those analyses, a 

decision was made to conduct additional modeling using a more current base year (2005). 

Examination of multiple base years provides for a more complete technical assessment. All 

modeling was conducted in accordance with USEPA modeling guidelines (USEPA, 2007).

February 27, 2008

For on-road, ammonia, and biogenic sources, 2005 emissions were estimated by emission 

models. For other sectors in the LADCO States, 2005 emissions were either supplied by a 

contractor (railroads and commercial marine) or by the States (point sources, area sources, and 

aircraft). For other sectors in non-LADCO States, a contractor obtained the latest base (2002) 

and future year emission files (2009, 2018) from the other Regional Planning Organizations

(RPOs) (Alpine, 2007a). Specifically, the following versions of these emissions files were used:

MANE-VU: Version 3.1, WRAP: Pre2002d, CENRAP: Base F, and VISTAS: Base F. The 2005 

emissions were then estimated by linearly interpolating between the 2002 and 2009 emissions. 

Further discussion of the development of the 2005 base year emissions is provided below:

On-Road: CONCEPT was run by a contractor using transportation data (e.g., VMT and vehicle 

speeds) for 24 networks supplied by the state and local planning agencies in the LADCO States 

and Minnesota (Environ, 2008). These data were first processed with T3 (Travel Demand 

Modeling [TDM] Transformation Tool) to provide input files for CONCEPT. For some networks, 

the VMT outputs from T3 were adjusted to match 2005 HPMS data. CONCEPT was then run 

with meteorological data for a July and January weekday, Saturday, and Sunday (July 15 – 17 

and January 16 – 18) to produce link-specific, hourly emission estimates. A spatial plots of 

emissions for July 15 are provided in Figure 2.

VOC Emissions NOx Emissions

Figure 2. July 15, 2005 motor vehicle emissions for VOC (left) and NOx (right)

For the non-LADCO States, CONCEPT was run by a contractor using RPO-based HPMS 

county-level data (2002 and 2009) and MOBILE6 inputs (2002) compiled by another contractor 

(Environ, 2008). HPMS VMT for 2005 were generated by linearly interpolating between the 

2002 and 2009 data. The 2002 MOBILE6 inputs were used for the 2005 modeling, with a few 

adjustments (e.g., fuel sulfur content was set to 30 ppm, as required by the Tier 2/low sulfur 

regulations). Meteorological data for a July and January weekday, Saturday, and Sunday (July 

15 – 17 and January 16 – 18) were used. 

For other months (for both LADCO and non-LADCO States), weekday, Saturday, and Sunday 

emissions were linearly interpolated based on the January and July emissions.

February 27, 2008

Off-Road: NMIM2005 was run by Grant Hetherington (Wisconsin DNR) to produce emissions 

for most off-road sectors for the LADCO States plus Minnesota, Iowa, and Missouri. Improved 

model inputs included local data for construction and agricultural equipment prepared by a 

contractor were incorporated (E.H. Pechan, 2004), and 2005 gasoline parameters. (Note, 

model updates prepared by AIR to address evaporative emissions were not included.)

EMS was run by LADCO using Grant Hetherington’s NMIM2005 data and, for the non-LADCO 

States, using emission files supplied by Alpine based on data from the other RPOs to produce 

weekday, Saturday, and Sunday emissions for each month.

Additional off-road sectors (i.e., commercial marine, aircraft, and railroads [MAR]) were handled 

separately. Aircraft emissions were supplied by the LADCO States. Updated information for 

railroads and commercial marine for the LADCO States was prepared by a contractor (Environ, 

2007a and Environ 2007b). Table 1 compares the new 2005 emissions with the previous 2002 

emission estimates. The new 2005 emissions reflect substantially lower commercial marine 

emissions and lower locomotive NOx emissions.

EMS was run by LADCO using the contractor and state data and, for the non-LADCO States, 

using emission files supplied by Alpine based on data from the other RPOs to produce 

weekday, Saturday, and Sunday emissions for each month.

Area: EMS was run by LADCO using 2005 data supplied by the LADCO States and, for the 

non-LADCO States, using emission files supplied by Alpine based on data from the other RPOs

to produce weekday, Saturday, and Sunday emissions for each month. Special attention was 

given to two source categories: industrial adhesive and sealant solvent emissions and outdoor 

wood boilers.

Industrial Adhesives and Sealants: The NEI shows this to be a large VOC 

emissions category in the LADCO States (i.e.., 50,000 TPY) USEPA 

subsequently determined that “(f)or the Region V states, we no longer believe 

that there are any activities in the Industrial Adhesives and Sealants category 

(SCC 2440020000) that have not been inventoried either in the point source 

Industrial Adhesives and Sealants category or under the Consumer and 

Commercial Adhesives and Sealants nonpoint category (SCC 2460600000 - all 

adhesives and sealants).” (USEPA, 2007b) Consequently, this category was 

omitted from the 2005 regional emissions inventory.

February 27, 2008

Outdoor Wood Boilers: Over the past several years, the installation and 

operation of outdoor wood boilers for residential use has increased dramatically 

in many northern states. Relying on an emission estimation methodology 

prepared by Bart Sponseller (WDNR, 2006), emissions were calculated by the 

other states for this category.

EGU Point:EMS was run by LADCO using 2005 data supplied by the LADCO States and, for 

the non-LADCO States, using emission files supplied by Alpine based on data from the other 

RPOs to produce weekday, Saturday, and Sunday emissions for each month. 2005 EGU 

emissions were temporalized for modeling purposes using profiles prepared by Scott Edick 

(Michigan DEQ) based on CEM data for the period 2004-2006. Profiles were generated for 

monthly weekday/Saturday/Sunday based on the median hourly emissions for that month, day, 

and hour of the day for the three years. Over 90% of NOX and SO2 emissions from EGUs in the 

LADCO states were assigned profiles. In non-Ladco states, the annual EGUs emissions were 

replaced with the 2005 sum of hourly emissions for all 365 days. 

Non-EGU Point: EMS was run by LADCO using 2005 data supplied by the LADCO States and, 

for the non-LADCO States, using emission files supplied by Alpine based on data from the other 

RPOs to produce weekday, Saturday, and Sunday emissions for each month. EGUs were 

removed from this point source file.

Other improvements to the base year inventory included:

Canadian Emissions: Previous modeling inventories for Canadian sources were flawed due to 

problems with emissions (e.g., LADCO inventories omitted ammonia emissions) or stack 

parameters (e.g., VISTAS inventories failed to include proper stack parameters, resulting in 

emissions getting dumped in the surface layer of the model). For Base M, Scott Edick 

(Michigan DEQ) processed the 2005 Canadian National Pollutant Release Inventory (NPRI –

see http://www.ec.gc.ca/pdb/npri/). Specifically, a subset of the NPRI data which are relevant to 

the air quality modeling were reformatted. A number of emission reports are available on the 

LADCO website (http://www.ladco.org/tech/emis/basem/canada/index.htm). Circle plot of point 

source emissions are presented in Figure 3.

Biogenic Emissions: A contractor provided an updated version of the CONCEPT/MEGAN 

(Model of Emissions of Gases and Aerosols from Nature – see http://bai.acd.ucar.edu/Megan/) 

biogenics model, which was used to produce base year biogenic emission estimates (Alpine, 

2007b). MEGAN includes functions for soil moisture plant stress, a more complete canopy 

model, full plant growth cycle emissions calculations, and state of the science emission rates.

Subsequent to deliver of the updated CONCEPT/MEGAN code, it was found that more recent 

data sets and model formulations were available. For the purposes of the Round 5 modeling, 

LADCO simply scaled the emission estimates from the updated code to reflect these newer 

data. This resulted in lower emissions for several organic aerosol species and NOx

Compared to the EMS/BIOME emissions used for Base K, there is more regional isoprene with 

MEGAN (see Figure 4). Also, with the secondary organic aerosol updates to the CAMx air 

quality model, Base M includes emissions for monoterpenes and sesquiterpenes, which are precursors of secondary PM2.5 organic carbon mass.

February 27, 2008

Ammonia Emissions: The CMU-based 2002 (Base K) annual ammonia emissions were 

projected to 2005 using growth factors from the Round 4 emissions modeling. These annual

emissions were then adjusted by applying monthly temporal factors based on the processbased ammonia emissions model (http://www.conceptmodel.org/nh3/nh3_index.html). The 

model was run for the following list of model farms using 2002 meteorological data: Dairy 

(California, Wisconsin), Swine (Iowa, Wisconsin), and Beef (Texas, Washington, Wisconsin). 

Because the model was not complete for the poultry housing model, swine was use in its place 

given that both use confined operations. 

Each model farms’ emissions were used to generate monthly average day emissions and a 

monthly profile. The profiles were applied to geographies most associated with that farm type

(e.g., all LADCO states used the Wisconsin farm results). The following figure shows the daily 

variation in emissions for the model farms.

including emissions from wild fires, prescribed fires, and agricultural burns. Projected emissions 

were also developed for 2010 and 2018 assuming “no smoke management” and “optimal smoke 

management” scenarios. An early model sensitivity run showed very little difference in modeled 

PM2.5 concentrations. Consequently, the fire emissions were not included in subsequent 

modeling runs (i.e., they were not in the Base K or Base M modeling inventories).

Future Year Emissions

Complete emission inventories were developed for two future years: 2009 and 20181. Source 

sector emission summaries for the base years (2002 – Base K and 2005 – Base M) and future 

years are shown in Figure 7. A more detailed state and source sector summary is provided in 

Attachment 1. Additional emission reports are available on the LADCO website 

(http://64.27.125.175/tech/emis/r5/round5_reports.htm.

 A 2008 proxy inventory was prepared to support a preliminary 2008 modeling analysis to assess 

attainment for the basic nonattainment areas (i.e, for areas with a 2009 attainment date, the appropriate 

panning year is 2008). This inventory reflects the following assumptions:

On-road: scale 2005 base year emissions using the Base K 2002 – 2009 trend (except for the 

Cincinnati-Dayton area, where 2008 emissions were generated using CONCEPT and 2008 data 

supplied by the local planning agency)

Off-road and area: scale 2005 base year emissions using the Base K 2002-2009 trend

Point – EGU: use 2005 base year emissions, with slight adjustment (-10%)

Point – Non-EGU: use 2005 base year emissions (note: Base K 2002-2009 trend suggests little 

change)

Biogenics: use new 2005 base year emissions

A 2012 proxy inventory was prepared to support a preliminary 2012 modeling analysis to assess the 

effect of further emission reductions from existing controls. This inventory was derived by interpolating 

between 2009 and 2018 emissions for all sectors, except point sources (for which, the 2009 emissions 

were used).

10
February 27, 2008

For on-road, off-road, and EGU sources, the future year emissions were estimated by models 

(i.e., CONCEPT, NMIM2005, and IPM, respectively) and then processed by LADCO with EMS. 

For other sectors (area, MAR, and non-EGU point sources), the future year emissions for the 

LADCO States were derived by applying growth and control factors to the base year inventory. 

These factors were developed by a contractor (E.H. Pechan, 2007). Growth factors were 

based initially on EGAS (version 5.0), and were subsequently modified (for select, priority 

categories) by examining emissions activity data. For the non-LADCO States, future year 

emission files were supplied by Alpine based on data from the other RPOs. Due to a lack of 

information on future year conditions, the biogenic VOC and NOx emissions, and all Canadian 

emissions were assumed to remain constant between the base year and future years. 

A “base” control scenario was prepared for each future year based on the following “on the 

books” controls (E.H. Pechan, 2007):

On-Highway Mobile Sources

• Federal motor vehicle emission control program, low sulfur gasoline, and ultra-low 

sulfur diesel fuel

• Inspection/Maintenance programs (nonattainment areas)

• Reformulated gasoline (nonattainment areas)

Off-Highway Mobile Sources

• Federal control programs incorporated into NONROAD model (e.g., nonroad diesel 

rule), plus the evaporative Large Spark Ignition and Recreational Vehicle standards

• Heavy-duty diesel (2007) engine standard/Low sulfur fuel

• Federal railroad/locomotive standards

• Federal commercial marine vessel engine standards

Area Sources

• Consumer solvents

• AIM coatings

• Aerosol coatings

• Portable fuel containers

Power Plants

• Title IV (Phases I and II)

• NOx SIP Call

• Clean Air Interstate Rule

• Clean Air Mercury Rule

Other Point Sources

• VOC 2-, 4-, 7-, and 10-year MACT standards2

• Combustion turbine MACT

• Consent decrees (refineries, ethanol plants, and ALCOA)3

 

2

 E.H. Pechan’s original control file included EPA-default control factor information. Alternative control 

factors were developed by Wisconsin for a few MACT categories, and were also applied to the other four 

LADCO States.

• Other (Illinois and Ohio NOx RACT4, and BART in IN and WI)

Further discussion of the development of the future year emissions is provided below:

On-Road: Similar to the base year modeling, CONCEPT was run using transportation data 

(e.g., VMT and vehicle speeds) supplied by the state and local planning agencies for 2009 and 

2018 (Environ, 2008). CONCEPT was only run with meteorological data for a July weekday

(July 15). The emissions for Saturday and Sunday were derived by using scaling factors based 

on the 2005 emissions. The state-level emissions for the five LADCO States plus Minnesota

are summarized in Table 25.

For the non-LADCO States, CONCEPT was run by Environ using HPMS county-level data and 

MOBILE6 inputs compiled by another contractor for VISTAS. Note, the emissions modeling for 

IA, MO, and OK was redone for 2009 to reflect the state-developed registration distribution data. 

(The initial modeling for 2009 used national default values for registration distribution assumed 

by VISTAS’ contractor. CENRAP’s contractor developed emissions inventories for 2002 and 

2018 using the state-developed data. For consistency, Environ’s remodeling for these three 

states for 2009 also used the state-developed data.) Meteorological data for a July weekday 

(July 15) were used. The emissions for Saturday and Sunday were derived by using scaling 

factors based on the 2005 emissions. 

For other months (for both LADCO and non-LADCO States), January weekday, Saturday, and

Sunday emissions were derived based on the July:January ratios for 2005, and then the 

weekday, Saturday, and Sunday emissions for other months were linearly interpolated based on 

the January and July emissions.

 

3

 E.H. Pechan’s original control file included control factors for three sources in Wayne County, MI. 

These control factors were not applied in the regional-scale modeling to avoid double-counting with the 

State’s local-scale analysis for PM2.5. 

4

 WI believes that NOx RACT for their sources is already included in the 2005 basecase and EGU “will 

do” scenario, and IN provided NOx RACT information for inclusion as a no-EGU “may do” scenario.

5

 For northeastern IL (CATS region), 2009 and 2018 emissions were increases by 9% and 8%, 

respectively, to reflect newer transportation modeling by CATS.

EGU Point: Future year emissions were based on EPA’s IPM3.0 modeling6. Three CAIR 

scenarios were addressed:

5a: EPA’s IPM3.0 was assumed as the future year base for EGUs. 

5b: EPA’s IPM3.0, with several “will do” adjustments identified by the States. These 

adjustments should reflect a legally binding commitment (e.g., signed contract, consent 

decree, or operating permit).7

5c: EPA’s IPM3.0, with several “may do” adjustments identified by the States. These 

adjustments reflect less rigorous criteria, but should still be some type of public reality 

(e.g., BART determination or press announcement).

Table 3 summarizes the SO2 and NOx emissions for the three scenarios. The individual 

facilities affected by the “will do” and “may do” adjustments are identified in Attachment 2. The 

net effect of these adjustments is a small increase in regional SO2 and NOx emissions.

Based on initial discussions with USEPA, a decision was made to use the 2010 IPM emissions 

in the 2009 modeling. USEPA subsequently insisted that 2009 modeling must represent 2009 

conditions. Because 2009 and 2010 EGU NOx emissions are expected to be similar (note: 

CAIR Phase I compliance date for NOx is 2009), the Round 5.1 ozone modeling was not 

redone.

USEPA believes that 2009 and 2010 EGU SO2 emissions may be significantly different (note: 

CAIR Phase I compliance date for SO2 is 2010). In particular, USEPA noted that information on 

projected scrubber installations identifies several facilities are not expected to be completed 

until 2010. A model sensitivity run was conducted with adjusted (higher) EGU SO2 emissions.

 

6

The second set of new IPM runs by EPA were used. These runs were performed at the request of the 

RPOs and reflect the addition of run years 2012 and 2018, and the use of four load segments for 2032 to

decrease model size (instead of six segments). Comparing the results in this run with EPA’s initial v3.0, 

showed small differences Below is a quick summary of the run year differences.

Table 4 provides information from USEPAs Clean Air Markets Division (CAMD) on scrubber 

installation dates. This information is based on various sources, including company 

announcements, consent decrees, vendors, and organizations that track scrubber installations.

While there may be uncertainty in any projection of control installations, USEPA considers these 

adequate projections for SIP planning purposes. 

USEPA identified six plants which: (1) are projected in IPM3.0 to have scrubbers in place by 

2010 (or 2011), but will not be completed by 2009, and (2) are most likely to impact PM2.5 air 

quality in the upper Midwest (see highlighting in Table 4). To reflect uncontrolled (2009) 

emissions for those facilities (and units), LADCO substituted actual 2005 emissions for the 

IPM3.0 projected 2010 emissions. The revised (2009) SO2 emissions for the six facilities (see 

Table 5) represent a 5-6% increase in domainwide SO2 emissions.
