Re: State Implementation Plan (SIP) revision for the Inventory of Ozone Precursor 

Emissions for 2011 (including Chicago and Metro-East St. Louis marginal nonattainment 

areas) 

Dear Dr. Hedman: 

Pursuant to Section 110(a)(2) of the Clean Air Act (CAA) (42 U.S.C. §7410 (a)(2)) and Section 

28 of the Illinois Environmental Protection act (415 ILCS 5/28), the Illinois Environmental 

Protection Agency (Illinois EPA) submits the Inventory of Ozone Precursor Emissions for 2011 

as a State Implementation Plan (SIP) revision, as required for the Chicago and Metro-East St. 

Louis areas classified as marginal ozone nonattainment areas in March 2008. This report 

additionally includes other areas of the state not classified as nonattainment. 

Notice of the public conunent period and opportunity for a hearing for the inventory was 

published in the Taylorville Breeze-Courier on July 11, 2014. The Notice was also published on 

the Illinois EPA's website. No comments were received on the inventory and no requests for a 

hearing were made. 

In order to assist with your review of this SIP submittal, one paper copy and one exact duplicate 

electronic copy of the documents listed below are enclosed:

Executive Summary 

This document provides the results of the Illinois Ozone Emission Inventory for 2011 

and a general description of the methods used to calculate the emissions. This 

inventory uses the up-to-date emission factors and calculation methodologies that were 

available at the time. The Illinois EPA is required to submit a complete emission 

inventory to USEPA every three years. A complete inventory includes point, area, and 

mobile (on-road and off-road) source categories. For an ozone inventory, daily and 

annual emissions of NOx and VOM are required. Resulting data is separated into the 

two nonattainment areas (Chicago and Metro-East St. Louis) and the attainment area 

(the remainder of the State). 

The primary source of data for point sources was the source-reported 2011 annual 

emissions reports (AERs). Area source emissions are typically estimated by multiplying 

an emission factor by a known indicator of activity (e.g., population) for a source 

category. On-road mobile source emissions were calculated using the MOVES 

computer model. Off-road mobile source emissions were calculated using the NMIM 

model. 

To ensure this inventory is of the highest quality, Illinois EPA implemented quality 

assurance (QA) procedures and quality control (QC) checks throughout the inventory 

development process. Illinois specifically followed the procedures outlined in USEPA’s 

guidance documents pertaining to inventory quality assurance and believes the 

inventory to be complete, accurate and of high quality.

1 Introduction 

Every three years (e.g., 2005, 2008, 2011, etc.) the Illinois EPA is required to conduct a 

full state-wide emissions inventory of ozone precursor emissions for all source 

categories (i.e., point, area, mobile). This document reflects the items included in the 

inventory plus the methodology used to calculate those emissions. Special emphasis is 

placed on the Chicago and Metro-East St. Louis (Metro-East) areas since they are 

designated as ozone nonattainment areas (NAAs). 

The Chicago NAA includes the counties of Cook, DuPage, Kane, Lake, McHenry, and 

Will, plus the Townships of Aux Sable and Goose Lake in Grundy County and Oswego 

Township in Kendall County. The Metro-East NAA includes the counties of Madison, 

Monroe, and St. Clair. 

The primary source of data for point sources was the source-reported 2011 annual 

emissions reports (AERs). Area source emissions are typically estimated by multiplying 

an emission factor by a known indicator of activity (e.g., population, employment, etc.) 

for a source category. Calculation of emissions for area sources primarily used 2011 

activity levels and in a few cases projections from previous years were used. Area 

source calculation methodologies were updated to the most recent calculation methods 

identified by USEPA. 

On-road mobile source emissions were estimated using the MOVES model. Off-road 

emissions were estimated using the NMIM model. The NMIM model does not include 

emission estimates for aircraft, locomotives, or commercial marine vessels. Aircraft 

emissions were calculated using actual activity data (operations) for each airport. 

Emissions from locomotives were grown from a study of the Eastern Regional Technical 

Advisory Committee (ERTAC). Commercial marine vessel emissions were obtained 

from a study of 2010 emissions by LADCO, which were then grown to 2011. 

To ensure this inventory is of the highest quality, Illinois EPA implemented quality 

assurance (QA) procedures and quality control (QC) checks throughout the inventory 

process. Illinois EPA specifically followed the procedures outlined in USEPA’s 

guidance.

2 Emission Inventory Summaries 

2.1 Background 

Four basic steps were involved in the preparation of the emission inventory. The first 

step was planning. As required by USEPA guidance, Illinois EPA prepared an Inventory 

Preparation Plan (IPP). This plan outlined the methods by which the Illinois EPA would 

assemble the 2011 inventory and perform QA/QC checks. The QA/QC plans and 

procedures are presented in Section 6.0. 

The second basic step was data collection. A major element in this step was to 

determine which source categories should be considered as point sources in the 

inventory and which should be considered area sources. Fundamentally different data 

collection procedures are used for these two source types. Actual emissions data 

reported in the sources’ AERs are used to collect point source data, whereas county 

level information such as population or employment is generally used to estimate area 

source emissions. The data collected and maintained on point sources is more detailed 

than area sources. 

The third basic step in the inventory compilation effort involved analysis of data 

collected and the development of emission estimates for each source. Emissions were 

determined individually for each point source, whereas emissions were generally 

determined for the overall area source category. Reported emission data, material 

balances and emission factors were all used to make these estimates. Adjustments 

were made to the VOM inventory to reflect only reactive VOM. 

The fourth step was reporting. Initially, Illinois EPA identified the kinds of data and 

formats that would be needed for this inventory document to fulfill USEPA inventory 

requirements. Later, Illinois EPA identified additional reports and features that would be 

useful for future inventory needs and/or modeling requirements. These have been 

incorporated into this document. 

Demographic data characterizing the various counties in the state are crucial to many of 

the emission estimation calculation procedures used to develop the inventory for area 

source categories. Also, in a number of instances, emissions are dependent to some 

degree on the geographic location of the county. In such instances, Illinois EPA 

developed factors based on whether counties were either a “Northern” or “Southern” 

county.

2.2 Methodology 

A detailed emission inventory for a pollutant lists each source of that pollutant and the 

quantity of its emissions. The sources are usually categorized in two ways: (1) point, 

area, or mobile sources or (2) industrial categories and subcategories. 

Emissions from point sources are defined as those whose emissions are usually fairly 

well characterized and are generally discharged through stacks and which are required 

to possess an Illinois EPA issued permit. Fugitive emissions are not emitted from a 

discrete point but are emitted from numerous areas throughout a facility. Area sources 

are usually spread over wide areas with no distinct discharge points or are comprised of 

a large number of small point sources that are difficult to describe separately (e.g., the 

heating furnaces in individual homes in a city) and whose emissions are not so well 

characterized. Other examples of area sources include architectural surface coating, 

automobile refueling, dry cleaning, and automobile refinishing. Mobile sources are 

divided into two major categories – on-road and off-road. On-road mobile sources 

include cars, trucks, buses, and motorcycles used for transportation of goods and 

passengers on roads and streets. Off-road mobile sources include other modes of 

powered transportation such as aircraft, locomotives, ships, and motor vehicles used 

off-highway. This classification protocol has been utilized throughout this document. 

A typical industrial plant may have different source types associated with it. For 

example, a refinery with numerous industrial processes would itself be a point source; 

the leaks from valves, pumps, and fittings throughout the miles of piping would be a 

fugitive source; and the switch engine that moves tank cars on the railroad siding would 

be an off-road mobile source. Also, a plant may have more than one industrial 

classification associated with it. The refinery in the previous example is in one industrial 

category; its tank farm is in another. Quantities of emissions may be measured directly 

(at the stack); they may be calculated from engineering principles (e.g., mass balance); 

or they may be estimated (e.g., by assuming reasonable emission rates, times, etc.). 

Further, emissions can be expressed in terms of annual emissions, seasonal emissions, 

or daily emissions. In the case of the pollutant ozone, precursor emissions are 

generally expressed in terms of typical daily emissions representative of the peak ozone 

season, or tons per day. 

Emission estimates presented in this report generally followed the methodologies 

outlined in USEPA’s emission inventory preparation guidance document, Volumes I-IV, 

and USEPA’s “Reporting Guidance for 1996 Periodic Emissions Inventories and 

National Emission Trends (NET) Inventories.” Where different estimation 

methodologies were used, such methods are identified. The emission estimates were 

seasonally adjusted to reflect average daily emissions during the summer months, 

which are generally considered the peak ozone season. For point sources, emissions 

were taken from source submitted data for the peak ozone season, as reported in their 

2011 AERs. Area source emissions were also modified using seasonal adjustment 

factors for the ozone season. Some sources have greater emissions on weekdays than 
5

on weekends. Emissions from all such sources have been adjusted to take 

weekday/weekend differences into consideration. 

The VOM emission estimates provided in this document are for those VOMs determined 

by USEPA to be photochemically reactive. All identified nonreactive VOMs were 

excluded from the VOM totals reported here for all sources and source categories.

· Cyclic, branched, or linear completely fluorinated ethers with no unsaturations 

· Cyclic, branched, or linear completely fluorinated tertiary amines with no 

unsaturations 

· Sulfur-containing perfluorocarbons with no unsaturations and with sulfur 

bonds only to carbon and fluorine 

2.2.1 Point Sources 

Emissions and source specific data for point sources were developed for the 2011 

inventory by Illinois EPA. The primary source of data for point sources was sourcereported emissions and permit files. These data are reported by the sources annually 

as part of the inventory process conducted by Illinois EPA and include emissions, 

process rates, operating schedules, emission control data, and other relevant 

information obtained from the permit files and plant inspections. The data was 

converted to an Access® database for processing and retrieval. Emissions were 

computed on a typical daily ozone season basis for each point source process using the 

original data. 
7

2.2.2 Area Sources 

Area source emissions were typically estimated by multiplying an emission factor by a 

known indicator of activity for each source category and each county. Area source 

emissions for 2011 were based on data available for population, employment, and the 

like. For the 2011 inventory, USEPA made available activity data at the county level for 

each state for many categories. Unfortunately this data was not always representative 

of 2011. In other cases, data was provided from national estimates. If data more 

specific to Illinois was available, it was used by Illinois EPA. Emission estimates for 

2011 emissions were developed using 2011 category activity levels, where available, or 

projections of changes in activity from 2008 or 2010 levels with a preference to data 

specific to Illinois. Emission controls were accounted for by using either adjusted 

emission factors or through the use of control factors. Appendix F includes the factors 

used to develop the emission estimates. Category summary tables reflecting Chicago 

and Metro-East NAA county emissions are also included. 

2.2.3 Mobile Sources 

On-road motor vehicle emissions were estimated by use of USEPA’s MOVES model. 

Inputs to run the model were provided by the Division of Mobile Source Programs within 

the Bureau of Air. The MOVES model is a significant departure from the previous onroad mobile source model so resulting emissions should not be compared to previous 

inventories. The MOVES model allows data to be pre-aggregated to different levels. 

Pre-aggregating data at a higher level than hourly reduces the time necessary for a 

calculation. An hourly run may take hours for a single county. For the ozone inventory, 

it was not necessary to do any pre-aggregation since the model ran sufficiently quickly 

in calculating daily emissions. Additional details on the types of data used in MOVES 

can be found in Section 5.0. 

Emissions were also estimated for off-road equipment. The vast majority of off-road 

mobile sources were calculated using USEPA’s NMIM model. The NMIM model does 

not calculate emissions for railroad locomotives, aircraft, or commercial marine vessels. 

Locomotive emissions were grown from the 2008 inventory. Commercial marine vessel 

emissions were obtained from a study funded by LADCO. Aircraft emissions were 

calculated using the number of landings and take-offs in conjunction with an emission 

factor. Further discussion of off-road equipment emission estimation methodologies 

and actual estimates are contained in Section 5.2. 

2.3 Results 

The 2011 Emission Inventory summary of the total ozone precursor emission estimates 

for the State of Illinois is shown in Tables 2-1 and 2-2. It covers the entire state. 
8

The magnitude of the total NOx and VOM emissions for the state by geographic region 

are delineated in the bar charts of Figures 2-1 through 2-4. The percentage 

contributions of the individual regions to the statewide total are shown in Figures 2-5 

and 2-6. The pie charts of Figures 2-7 through 2-14 present the total ozone precursor 

emissions by source category for each geographic region of the state. 

Figures 2-15 through 2-18 show the emissions of the source categories for the previous 

three inventories and the current inventory. It is important to note that while a general 

trend can be identified, two inventory years may have had different methodologies to 

calculate emissions. This is particularly the case with on-road and off-road emissions in 

2011. The models (MOVES and NMIM) used to calculate on-road and off-road 

emissions were completely different from previous inventory years. Using updated 

emission factors between inventories most commonly occurs with the area source 

category. Point sources are the most comparable from year-to-year since the emission 

factors do not typically change often. 

Category summaries by pollutant for the 2011 statewide inventory are given in 

Appendices A through D. Appendix E presents a county-by-county summary of point, 

area, on-road, and off-road emissions. Appendix H includes the surrogates used to 

apportion area source emissions to the nonattainment townships (portions of counties).

3 Point Sources 

A major distinction typically made in emission inventories is the distinction between 

point and area sources. The Illinois EPA maintains detailed, unit-by-unit data for 

permitted sources. This data is obtained from permit applications and AERs. Since the 

Illinois EPA has very few de minimus emission exemptions from permitting, the 10 ton 

per year inventory requirement imposed by USEPA inventory guidance is more than 

adequately met for Illinois sources with permits. It is not uncommon for emissions from 

a permitted source to be much less than 10 tons/year. At this time, the Registration of 

Smaller Source (ROSS) program has not affected the smaller emitting sources included 

in the 2011 inventory. 

The sources described above are known as point sources. The area source inventory 

includes all other stationary sources not included in the point source inventory. In cases 

where the two categories overlap (e.g., fuel combustion and solvent use), care has 

been taken to not double-count emissions. Area sources are covered in Section 4. The 

point source inventory described herein is considered to be the most current and 

accurate source of emission data available for 2011. 

3.1 Source Identification and Data Collection 

The sources to be included in the 2011 inventory were identified using the Illinois EPA’s 

ICEMAN database. All operating sources that existed in ICEMAN as of the end of 2011 

are included in this inventory. 

The 2011 point source inventory was prepared by the Illinois EPA using source reported 

data from AERs. When a source failed to submit an AER for 2011, other data such as 

previous Illinois EPA estimates were used. 

3.2 Emission Estimation Methodologies 

Source reported actual emissions are used in the 2011 ozone inventory. AERs 

provided the ozone season hourly emissions and operating schedules that enabled the 

calculation of ozone season weekday emissions. Where operating schedules were 

missing or not required to be reported, Illinois EPA estimates were used. These 

estimates came from previously-submitted AERs or from permit applications. Typical 

emission estimation methodologies include material balance and emission factors. 

Since the inventory included VOM emissions, care was taken to exclude 

photochemically non-reactive materials. Emission rates from these types of materials 

are stored separately from VOM in ICEMAN so it was a simple task to exclude their 
30

emissions. The list of the compounds that USEPA has identified as being 

photochemically non-reactive is included in Section 2.2. 

3.3 Point Source Emissions 

Table 3-1 includes the emissions from all sources classified as point sources.

4 Area Sources 

Area sources are those activities for which aggregated source and emission information 

is maintained for entire source categories rather than for each individual source. The 

Illinois EPA is responsible for preparing the area source emission inventory. The area 

source inventory includes NOx and reactive VOM for the entire state. Emission 

estimates are presented for the ozone nonattainment areas of Chicago and Metro-East 

St. Louis, as well as the remaining part of the state, which is in attainment with the 8-

hour ozone standard. Where no township-specific information was available for the 

Chicago NAA counties of Grundy and Kendall, apportioning factors were developed and 

applied to estimate area source activity. 

4.1 Source Identification 

Area source categories of NOx and VOM emissions have been identified primarily 

through previous inventories. These inventories have followed previous guidance and 

have been found to be complete. As more is learned of emissions and emission 

sources, USEPA introduces new source categories for area sources. Illinois EPA 

reviewed this list and incorporated the new categories, as appropriate, added since the 

last inventory. 

Care is also taken when identifying potential area source categories. As stated 

previously, Illinois EPA’s point source inventory for 2011 has a very low threshold of 

emission rates. This means that categories classified as area sources in other states 

are included solely in the point source inventory for Illinois. The best example of this is 

coal combustion in industrial and commercial boilers. It is believed that all boilers of this 

type are permitted and therefore exist in the point source inventory. In cases such as 

this, Illinois EPA reports zero emissions for the area source category to USEPA. 

Reporting zero emissions removes all doubt whether the category was overlooked or 

not. Categories the Illinois EPA assumes are covered completely in the point source 

inventory include: 

· Cremation (animal and human) 

· Fuel combustion 

o Commercial/Institutional 

§ Coal 

§ Wood 

o Industrial 

§ Coal 

§ LPG 

§ Wood 

· Fuel marketing 

o Bulk plants 

o Bulk terminals 
32

· Surface coating 

o Aircraft 

o Appliances 

o Marine 

o Metal cans 

o Metal coils 

o Metal furniture 

o Motor vehicles 

o Railroad 

o Wood furniture 

4.2 Emission Estimation Methods 

4.2.1 Calculation Methodologies 

Several methodologies have been used in estimating area source emissions. 

· Emission factors 

o Standard (e.g., lb/person, lb/acre) 

o Formula (methods that may require multiple data values) 

· Growth factors 

· Data from inventories compiled by others 

In most cases, emissions were calculated by an emission factor. A listing of these 

emission factors can be found in Appendix F. 

In two cases, emissions were calculated by using a growth factor to convert 2008 

emissions to 2011 emissions. It should also be noted that for some of the fuel 

combustion categories, consumption data for some fuels was only available for calendar 

year 2010. However, the natural gas consumption rate was available for 2011. If the 

most recent year of data for a fuel was 2010, it was grown to a 2011 value by using the 

ratio of natural gas consumption for 2011 to that of 2010. Growth factors that were 

used are identified in Appendix F. 

In some cases, data provided by the USEPA was used in compiling the 2011 area 

source inventory. These area source categories include: 

· Fuel marketing 

o Stage I 

o Stage II (diesel and gasoline) 

· Portable fuel containers 
33

4.2.2 Sources of Data 

Various sources have been used to determine activity/commodity level data and 

emission information for area source inventory purposes. Among these are the 

USEPA’s AP-42, USEPA’s FIRE emission factor database, and data from federal and 

state agencies including USEPA’s Office of Air Quality Planning and Standards, the US 

Department of Energy, US Bureau of Labor Statistics, Illinois Department of 

Transportation, Illinois Department of Agriculture, and so on. 

4.2.3 Rule Effectiveness and Rule Penetration 

For area sources subject to a VOM control equipment regulation, a rule effectiveness 

(RE) factor has been applied to the control efficiency when determining the emission 

rates. The RE adjustment reflects the assumption that regulations typically are not 100 

percent effective at all sources at all times. For example, if a RE factor of 95 percent 

has been assumed, a value of 0.95 is multiplied against the control efficiency before 

subtracting the efficiency from unity. 

In cases where a control regulation is applied to an area source category, a rule 

penetration (RP) adjustment may be required. The RP factor takes into account the fact 

that, due to exemptions within the rule, all sources within the category may not be 

regulated. Illinois EPA has used best judgment in the development and application of 

such factors. 

Due to the use of emission factors, rather than the independent calculation of 

uncontrolled emissions and subsequent control efficiencies, the use of RE and RP 

factors is limited. In addition, a number of rules regulating area source emissions deal 

with operational behavior (e.g., keeping the lid closed on a cold-cleaner) rather than the 

addition of control equipment. 

4.2.4 Double Counting of Emissions 

A major concern in the development of an area source inventory is the possibility of 

double-counting emissions. Because some area source methodologies estimate 

emissions from all sources within a category, emissions already contained in the point 

source inventory may also be included in the area source estimate. In these instances, 

the point source emissions must be subtracted from the gross area source estimate to 

determine the net area source estimate. Commonly affected area source categories 

are: 

· Dry Cleaning 

· Fuel Combustion 

· Graphic Arts 
34

· Incineration 

· Solvent Cleaning 

4.2.5 Annual Emissions to Daily Emissions Calculation 

Emissions contained in this Section have been expressed in tons/day and tons/year. 

Activity levels and/or emission factors are frequently based on longer timeframes than a 

daily timeframe, so adjustment factors have been applied to estimate the typical 

summer weekday emissions. In order to determine the ozone season activity fraction, a 

seasonal adjustment factor is applied to the annual emission estimate. This factor 

compares the summer season percentage of annual activity for the specific category to 

a uniform seasonal activity level (25 percent). Therefore, if 30 percent of a certain 

activity occurs during the summer season, the seasonal adjustment factor would by 30 

 ̧ 25 or 1.2. 

In order to estimate emissions on a typical weekday, an activity adjustment factor is 

applied to the annual emission estimate. This factor is developed in one of two ways. 

First, the factor can be developed by dividing by the number of days per week an 

activity occurs and that total divided by 52, the number of weeks in the year. Therefore, 

the activity adjustment factor for an activity which occurs uniformly, seven days a week 

is calculated using the following equation: 1  ̧ 7  ̧ 52 = 0.00275. 

The second method is used when a percentage of work-week (Monday-Friday) activity 

has been developed. In this case, a work-week percentage of 33 percent activity 

converts into an activity adjustment factor by dividing 0.33 by 5 for the number of days 

the activity occurs divided by 52 which equals 0.00127. 

A listing of these seasonal and daily adjustment factors can be found in Appendix G. 

4.2.6 Estimating Emissions at the Township Level 

In addition to the counties of Cook, DuPage, Kane, Lake, McHenry, and Will, the 

Chicago NAA also includes Aux Sable and Goose Lake Townships in Grundy County 

and also Oswego Township in Kendall County. Township-specific area source activity 

data is not always available. County emissions are apportioned to the township level 

using other surrogates related to the activity being estimated. These surrogates and 

their resulting percentages are included in Appendix H.

5 Mobile Sources 

A mobile source of air pollution is a self-propelled or portable emitter of air pollutants. 

Emissions are generated by the engines or motors that power such sources. Most 

mobile sources, except jet or turboprop aircraft, are powered by internal combustion 

piston engines and nearly all use liquid fuels. Gaseous fuels, such as compressed 

natural gas (CNG) or liquefied petroleum gas (LPG), have a very small fraction of the 

motor fuel market in Illinois. Solid fuels have not been used by mobile sources in 

significant amounts since railroads retired their coal-powered steam locomotives in the 

1950s. 

For inventory and planning purposes, mobile sources are divided into two major 

categories. 

1. On-road mobile sources (e.g., motor vehicles such as cars, vans, trucks, buses 

and motorcycles) used for transportation of goods and passengers on roads and 

streets 

2. Off-road mobile sources including: 

· Modes of powered transportation that do not use roads, such as aircraft, 

trains, ships and boats, and motor vehicles used off-road; and 

· Self-propelled or portable motorized machines or equipment not used for 

transportation, ranging from construction equipment and farm tractors to 

lawnmowers and hand-held power weed choppers. 

All on-road mobile sources are self-propelled. Some off-road mobile sources (e.g., farm 

tractors) are self-propelled, but many off-road sources are not. A gasoline-powered 

chainsaw is a familiar example of a non-self-propelled off-road mobile source. Not all 

movable or portable emission sources are mobile sources, however. A small truckportable cement or hot-mix asphalt plant, for example, may be set up near a 

construction or road-building site. Such plants are classified as stationary sources, not 

mobile sources, for two reasons: (1) they may operate for weeks or months at a single 

location, and (2) the trucks that move the plants do not supply power for them. 

Not all internal combustion or turbine engines are mobile sources. Fixed internal 

combustion engines are classified as stationary sources. 

There are three categories of mobile source emissions: 

· Exhaust or tailpipe emissions, which result from the combustion of fuel in the 

source’s engine

· Evaporative emissions, which result from evaporation of fuel from the engine or 

its fuel system; and 

· Refueling emissions 

Exhaust emissions are the result of fuel combustion and occur only when the engine is 

running. 
66

Evaporative emissions are VOM only and are continuously emitted from an engine’s 

fuel system, whether the engine is running or not. Evaporative and exhaust VOM 

emissions were calculated separately for most mobile source categories in this 

inventory, but for purposes of this report they have been combined. Evaporative 

emissions do not include VOM emissions that occur during refueling. 

Refueling emissions are a third category of mobile source emissions. Refueling 

emissions are entirely VOM. Although they result from the evaporation of fuel, they are 

distinct from, and not directly related to, evaporative emissions as defined above. 

Refueling emissions have two subcomponents: 

· Displacement emissions. These occur when new fuel is transferred into a partly 

filled tank (be it a service station storage tank, a portable fuel container or gas 

can, or a vehicle or engine’s fuel tank), displacing the air in the tank and forcing 

that vapor-rich air out the inlet pipe or other vent. There are two stages of 

displacement emissions: 

o “Stage I” emissions occur when the underground storage tanks at a 

service station are being refilled; 

o “Stage II” emissions occur when a motor vehicle (or gas can) is being 

refueled. 

· Spill emissions. These occur when drops of fuel drip or splash on the ground 

during or after refueling and evaporate away. 

Refueling emissions from on-road sources occur almost entirely at commercial or 

private service stations and have been included in the area source category. 

Off-road sources also have refueling emissions. Some off-road sources (e.g., 

locomotives, aircraft, and boats) are refueled at fixed locations. However, many small 

non-highway sources (e.g., lawnmowers) are refueled where they are used from mobile 

or portable tanks or fuel containers. In this inventory, refueling emissions from off-road 

categories (except aircraft refueling) are not reported separately from exhaust and 

evaporative emissions, but rather are included in the reported overall off-road VOM 

emissions. Emissions from portable fuel containers are included in the area source 

category. 

5.1 On-Road Mobile Source Inventory 

The inventory of on-road mobile source emissions contains Illinois EPA’s estimates of 

the amounts of NOx and VOM from highway vehicles statewide by county as calculated 

using USEPA’s MOVES model. Exhaust and evaporative emissions were calculated 

separately but have been combined for this report. The MOVES model allows data to 

be pre-aggregated to different levels. Pre-aggregating data at a higher level than hourly 

reduces the time necessary for a calculation. An hourly run may take hours for a single 

county. The calculation of daily emissions was deemed to be quick enough so no preaggregation was performed. The estimates given here for on-road sources do not 
67

include refueling emissions. On-road motor vehicle refueling emissions are found in 

Section 4. 

5.1.1 On-Road Motor Vehicle Types 

Emissions are reported for 12 vehicle types corresponding to the vehicle types for which 

the MOVES emission factor model reports emissions for the submittal of data to 

USEPA. The vehicle types are described below.

LDGV Light-duty gasoline vehicles (passenger cars) 

LHDDV Light heavy-duty diesel vehicles (10,001 – 16,000 lb 

GVW) 

MC Motorcycles (gasoline) 

MHDDV Medium heavy-duty diesel vehicles (16,001 – 33,000 lb 

GVW) 

Different types of vehicles have different emission characteristics. Larger and heavier 

vehicles emit more than smaller, lighter vehicles using the same fuel. Generally 

speaking, diesel vehicles also emit less VOM but more NOx than their gasoline 

equivalents. 

5.1.2 Model Input Data 

The MOVES model allows the use to input various data used to calculate emissions into 

the model’s database. If the user is sufficiently skilled, he can enter data directly into 

the database. Another method to import data into the database is to create a 

spreadsheet that includes multiple tabs. Each of those tabs represents a different table 

in the database. An XML file is created that tells MOVES which spreadsheet to use and 

which tabs of the spreadsheet are to be imported. This is the methodology the Illinois 
68

EPA used. A spreadsheet was created for each county and was imported into the 

database. The tabs of the spreadsheet and a description of the type of data in the tab 

are described in the table below. 

Table 5-2: User Supplied Data for MOVES Model 

Spreadsheet Tab Description of Data in Tab 

Age Distribution The fraction of vehicles of a certain age for a given 

vehicle type. 

Average Speed Distribution The fraction of traffic for a given vehicle type, road type, 

hour of day and speed bin. 

Day VMT Fraction The fraction of VMT for a given vehicle type, month, 

road type and day. 

Fuel Formulation The RVP, sulfur level, ethanol volume, aromatic 

content, olefin content, benzene content of a fuel. 

Fuel Supply The market share of a given fuel for a particular month. 

Hour VMT Fraction The fraction of VMT for a given vehicle type, road type, 

day and hour. 

HPMS VType VMT for a given vehicle type 

I & M Coverage Type of program, inspection frequency, applicable 

model years, compliance factor. This data was 

provided only for the counties that are in a 

nonattainment area. 

Month VMT Fraction The fraction of VMT for a given vehicle type and month. 

Road Type The fraction of ramp traffic for a given road type. 

Road Type Distribution The fraction of VMT for a given vehicle type and road 

type. 

Source Type Number of vehicles for a given vehicle type. 

Zone Month Hour The temperature and relative humidity for a given 

month and hour of the day. 

This information, and other data internal to MOVES (e.g., emission factors) was then 

used by the MOVES model to calculate emissions. 

5.1.3 On-Road Mobile Source Emissions Summary 

Table 5-3 is a summary of the on-road mobile source emissions in tons per year. 

Detailed tables of on-highway mobile source emissions are given in the appendices.

5.2 Off-Road Mobile Source Inventory 

Off-road modes of transportation include trains (i.e., locomotives), aircraft, ships and 

boats, and motor vehicles used off-road. Several factors make off-road emissions 

important in Illinois. Illinois is at the heart of commercial aviation and the railroad 

network in the United States and much of the waterborne commerce originates in or 

passes through Illinois waters. In particular, the Chicago and the St. Louis area are 

both major centers of air and rail traffic. O’Hare Airport in Chicago is one of the busiest 

in the world. Waterborne commerce on the Illinois, Mississippi, and Ohio Rivers and on 

Lake Michigan is considerable, and the state is well supplied with rivers and lakes 

where much recreational boating takes place. 

5.2.1 Railroad Locomotives 

Rail traffic in Illinois is powered almost entirely by diesel locomotives. Most rail traffic in 

Illinois is freight, but there are several major Amtrak passenger routes in Illinois and an 

extensive diesel-powered commuter rail network (METRA) centered on Chicago. The 

major (Class I) railroads – Burlington Northern, Santa Fe, Canadian National, Canadian 

Pacific, CSX, Kansas City Southern, Norfolk Southern, and Union Pacific – all operate 

in Illinois, and most rail traffic is on their routes. There are also nearly 40 regional and 

short lines in the state. Most of these smaller railroads are very small – a few miles of 

track and an engine or two – but some have several hundred miles of track in the state 

and transport millions of tons of freight. 
70

5.2.1.1 Calculation of Emissions 

The Eastern Regional Technical Advisory Committee (ERTAC) was established by a 

group of states to support effective air quality planning. One of the categories of 

interest to standardize the inventory and improve data quality was the calculation of 

railroad locomotives. The major goal of the group was to build a link-level, spatially and 

temporally allocated emission inventory. 

The Illinois EPA used the 2008 inventory and applied a growth factor of 1.053 to obtain 

2011 emissions. 

5.2.1.2 Railroad Locomotive Emissions 

The following table represents the emissions calculated in Round 5 of the ERTAC Rail 

Committee.

5.2.2 Aircraft 

This inventory deals with aircraft emissions at Public Use Airports and military airfields 

in Illinois. There are many small, private airstrips and restricted landing areas scattered 

around the state. These airstrips are not public use in that they are not open to the 

flying public. Data, in general, is not available for these private airstrips, but few have 

more than a handful of operations a month involving small piston engine aircraft which 
71

results in extremely negligible emissions. Emissions from these private airstrips have 

not been included in the inventory. 

5.2.2.1 Aircraft Description 

The FAA recognizes four categories of aircraft operations: 

· Air Carrier or Commercial operations: large aircraft capable of carrying more 

than 60 passengers or 18,000 pounds cargo, i.e., scheduled major airline 

operations. 

· Air Taxi operations: smaller aircraft than air carrier, i.e., small-scale passenger 

operations. 

· General Aviation: all other non-military aircraft operations including private, 

business, and civilian government operations. 

· Military: all operations by military aircraft. 

The FAA collects and publishes statistics on these categories for many airports 

nationwide. Large commercial airports usually have detailed information on aircraft 

operations by various aircraft makes and models and sometimes even engine types. 

There are two basic types of aircraft engines: 

· Turbine, turboprop, or turbojet engines which power virtually all military and 

commercial and many business aircraft. These use jet fuel, a kerosene blend of 

low volatility. 

· Piston engines which power most small general aviation aircraft, private planes, 

and some business aircraft. These use a special high-octane aviation gasoline. 

These aircraft operate chiefly in five modes: 

· Taxi/Idle: at very low power when idling or during taxiing before taking off or after 

landing. 

· Takeoff: at full power during takeoff until the aircraft is about 500 feet above the 

ground. 

· Climbout: at slightly reduced power during which the aircraft climbs to its cruising 

altitude. 

· Cruise: at further reduced power level at cruise where the aircraft maintains a 

constant speed and altitude. 

· Approach: at a moderate to low power level during descent and the approach to 

landing. 

Cruising emissions are not included in the inventory. 
72

5.2.2.2 Estimating Emissions from Aircraft Operations 

Emission factors for aircraft are usually expressed as mass of pollutant per LTO and are 

derived from measurements made by engine manufacturers. The emission factor for a 

given aircraft is a function of the make and model of the aircraft and its engine(s), the 

number of engines on the aircraft, the fuel flow rate for each mode, and the time the 

aircraft spends in each mode. 

Emissions are calculated by summing the emission factors from each of the four modes 

of operation (taxi, takeoff, climbout, and approach) to obtain a single emission factor for 

a single LTO. This value is then multiplied by the number of LTOs for the given 

aircraft/engine type to obtain emissions. Emission factors used in calculating the 

inventory are given below. 

Table 5-5: Fleetwide Aircraft Emission Factors (lb/LTO) 

Aircraft NOx VOM 

Air Taxi - Piston 0.16 0.17 

Air Taxi – Turbine 0.78 1.01 

Commercial 18.58 5.87 

General Aviation – Piston 0.07 0.15 

General Aviation – Turbine 0.32 0.55 

Military 0.16 1.36 

In addition, APUs are small turbine engines installed in the hulls of many large and 

medium aircraft to generate electricity and compressed air to keep the aircraft’s systems 

operating when the main engines are off. APUs use jet fuel and generate exhaust 

emissions like the main engines do. Most aircraft in the commercial category have 

APUs, but comparatively few air taxi or general aviation aircraft have them. 

APU emissions for an aircraft are the product of its APU’s emission factor (pounds per 

hour of operation), the time in use (hours per LTO), and the number of LTOs. APU 

emissions are assumed to be negligible for all airports except Midway and O’Hare, 

which can be found in Table 5-7, below.

This category includes large cargo ships, passenger ships, oil tankers, etc., powered by 

steam or internal combustion engines and used for commercial purposes such as 

transport of passengers, cargo movement, commercial fishing, and the like. Tugboats 

and pushboats, both used in harbors and to propel barges on rivers, are included in this 

category. Emissions for pleasure boats are not included in this category, but rather in 

the other non-road engines and vehicles category. 

LADCO funded a study (Commercial Marine Emissions in the LADCO Region –

September 2011) by Energy and Environmental Research Associates, LLC and Alpine 

Geophysics to provide a better estimate of emissions for the Region V states. The 

emissions provided in this report were for the calendar year 2010. Illinois EPA used a 

growth factor of 1.0111 to obtain 2011 emission rates

5.2.4 Other Off-Road Engines and Vehicles 

This category includes all other portable motorized equipment, from lawnmowers to 

forklifts, and farm tractors to earthmoving equipment. Engines are powered by sparkignition (usually fueled by gasoline) and some by compression ignition (diesels). There 

are two types of spark-ignition engines: 2-stroke and 4-stroke. The three types of 

engines, 2-stroke, 4-stroke, and diesel, have very different emission characteristics, so 

they are treated separately in the inventory. Some off-road emission sources use CNG 

or LPG as a fuel. 

For this inventory, Illinois EPA used the NMIM model from USEPA to estimate off-road 

emissions by county. The amount of input data used by NMIM is significantly smaller 

than that used in MOVES. Fuel and temperature data previously compiled for MOVES 

was also used in NMIM. The equipment populations included with NMIM were not 

modified and were used as they existed in the model. 

Emissions calculated for other off-road engines and vehicles for the 2011 inventory are 

as follows:

6 Quality Assurance 

6.1 Purpose of the Inventory 

The objective of this emission inventory is to present an accurate and comprehensive 

account of ozone precursor emissions from point, area, and mobile sources for the 

entire State of Illinois in accordance with the requirements of the CAA. The ozone 

precursors included in the inventory are NOx and VOM. Emissions presented in the 

2011 emission inventory are typical summer day and annual. 

6.2 Scope of the Quality Assurance Plan 

The Illinois EPA has implemented quality assurance (QA) procedures and quality 

control (QC) checks at various stages in the inventory process. The QA preparations 

involved in the development of the emission inventory were based on the procedures as 

outlined in the USEPA’s publications EPA-450-4-88-023, Guidance for the Preparation 

of Quality Assurance Plans for O3/CO SIP Emission Inventories and EPA-450/4-91-

022, Quality Review Guidelines for 1990 Base Year Emission Inventories and Illinois 

EPA’s document, Illinois Environmental Protection Agency Point Source Emissions 

Inventory Quality Assurance/Quality Control (QA/QC) Plan by the Radian Corporation 

(November 1991). Details of the QA program are discussed in the following sections. 

6.3 Summary of QA Activities 

In general, four basic stages were involved in the preparation of the 2011 emission 

inventory: planning, data collection, data analysis, and data reporting. Data analyses 

include estimation of emissions for point sources that failed to report ozone season 

emissions in their AER. The reporting stage includes the presentation of summer ozone 

season data and emission estimates as a finished product in the required format. As a 

first step, the QA program was conceived earlier in the process and was implemented 

throughout the various stages of inventory development. Second, the collection of data 

(or representative samples of it) had undergone review for suitability, completeness, 

and correctness. Next, all the methodologies used in the calculation of missing or 

unreported emission data and those methodologies used for various data analyses 

were all reviewed to ensure the inventory of such emission data were appropriate 

representations of each respective emission category. Lastly, the finished periodic 

emission inventory product was checked and audited for completeness and accuracy. 

6.3.1 Inventory and QA Planning 
78

Illinois EPA’s Air Quality Planning Section inventory staff used a QA plan largely based 

on requirements according to the CAA and USEPA quality assurance and quality 

control guidance documents. Also, the overall inventory QA plan was influenced by 

experiences gained in the development of previous inventories. 

6.3.2 Resource Allocation for QA 

In-house quality assurance activities required a person with experience and authority to 

carry out QA duties. The QA coordinator (QAC) interacts directly with the inventory staff 

or specialists for point, area, and mobile sources. The person responsible for this 

activity is the manager of the Inventory and Data Support Unit of the Air Quality 

Planning Section. As of the creation of this inventory, there were six staff under this 

manager whose jobs are to compile the point source inventory, review AERs, and 

compile the area source inventory. 

6.3.3 Schedule and Project Planning 

The Air Quality Planning Section’s inventory staff’s experience in the compilation of 

previous inventories was drawn upon in preparing the QA plan for the 2011 emission 

inventory. 

To prepare the 2011 AER data for inventory use, inventory staff reviewed the emission 

data that was submitted. The experiences in such review were also included as bases 

in developing the QA plan for this inventory. Many data range checks are built into the 

CAERS and ISSIS systems. This ensures values entered into the database are within 

acceptable levels such as those ranges of values for parameters indicated in Section 

6.4. Knowledge that such input value ranges are automatically validated contributed to 

the overall design of the QA plan. 

As permits are issued, the emission data contained in the permit and application are 

compiled into the point source emission inventory by the inventory staff. Each source 

that is added to the inventory is reviewed for correctness and completeness by the Unit 

Manager. This review also contributes to the contribution of the overall design of the 

QA plan. 

A review of the results of the AER data became the groundwork for planning and 

scheduling the QA efforts for the 2011 inventory. Specific key parameters identified in 

the inventory were tagged as a potential focus for QA work and incorporated in the 

planning for reviewing the point source emissions data. 

The inventory staff charged with the mobile and area source portions of the inventory 

began their parallel QA efforts to enable a timely completion of the inventory. For onroad and off-road sources, review of emission factors was primarily confined to QA of 
79

the inputs to the appropriate model. The non-road source methodology and emission 

data were compared with previous studies done on this category. 

6.4 QA Technical Information 

As noted above, the emission inventory system the DAPC uses contributes to the 

overall quality assurance aspect for this inventory. The emission inventory data has 

already been range checked for the following parameters: 

· Stack height ≤ 1250 feet

· Stack diameter ≤ 99.99 feet

· Hours per year ≤ 8760

· Peak ozone season hours ≤ 2190

· Weeks per year ≤ 52

· Peak ozone season weeks ≤ 13

· Days per week ≤ 7

· Hours per day ≤ 24

· Seasonal throughput totals = 100 percent 

In addition to the validation of input data ranges, ISSIS and CAERS also perform 

automated validation of codes such as SIC and SCC. With such tasks performed, the 

inventory staff is more focused on reviewing key parameters and other aspects of the 

inventory that may significantly affect the accurate representation of typical summer 

weekday emissions. 

6.4.1 Prioritizing Sources and Data Elements 

The data elements of the 2011 periodic emission inventory were based on the sourcereported emissions for 2011. This reported data was deemed more representative 

compared to the emissions from growing a previous point source inventory. An analysis 

was performed by comparing the emission level in 2008 and 2011 on a point-by-point 

basis. With tens of thousands of records statewide to QA for purposes of this inventory, 

this methodology helped to focus resources towards emission points that were found to 

have a significant increase or decrease in emissions from 2008 to 2011. 

Sources whose summation of emissions from the individual emission units at the source 

were significantly different than the source-reported total were sent a letter identifying 

the discrepancy. As revised data was received, it was checked to make sure the error 

was corrected. This updated data was entered into ICEMAN and used for the inventory. 

6.4.2 Data Sources and Checking Procedures 
80

Although the data used in the point source emission inventory came directly from the 

sources themselves, some data were deemed incorrectly represented and corrected 

accordingly. If necessary, all possible sources of information were used in this QA 

effort, including AERs from previous years, to determine reliability of the data for 

inclusion in the inventory. The inventory staff assessed all data that were presented 

and took into account the capabilities and biases of the organization supplying the data, 

the techniques used to collect the data, and the purpose for which the data had been 

compiled. All of these provided an overall understanding of the limitations of reported 

data and served as a guide in choosing the best data for use in the inventory. 

All reported data from a source’s 2011 AER were checked and entered into CAERS. 

The point source reported data were reviewed and, in general, found acceptable as 

most companies had provided the necessary information required by Illinois EPA. Area 

source data, such as census and meteorological information, landings and takeoffs at 

airports, etc. came from federal or state government sources and are relatively accurate 

and found to be appropriate for use in this inventory. Data from high-quality sources are 

still subjected to QA checks for relevance and suitability for the inventory. For example, 

LTO data provided by USEPA was found to be three times larger for some airports (i.e., 

O’Hare) than what three other references identified. For this reason, the USEPA data 

was ignored. Other data for area sources may be several years old or were obtained in 

aggregate form (i.e., nationwide or statewide rather than by county or city) and are 

subject to further scrutiny. These sets of data underwent the same checks as the 

higher quality data and were reviewed with greater attention to bias and collection 

techniques. 

Review of the emission data was generally performed several times in the inventory 

development process. The inventory staff reviews the data as presented by each 

source to Illinois EPA. The QA Coordinator, through comparative analysis and other 

database review/manipulations, sorts and flags suspect emission points and values and 

returns them to the responsible inventory staff for another round of QA review and 

scrutiny. Finally, after the consolidated emission results are finalized, the inventory staff 

performs a last review of emission values for inclusion in the inventory. The second 

independent QA check is more formal than the other two and is usually done on a 

sample of the data. The first and third checks cover all data used. 

6.5 Data Collection and Analysis 

The following sections describe Illinois EPA’s plans in collecting and analyzing emission 

data and the QA procedures used by the inventory staff in evaluating them. 

6.5.1 Identification of Emission Sources 
81

For point sources, all sources that (a) are located in the State of Illinois and (b) are 

shown to have emissions of NOx or VOM are automatically included in the inventory. 

Illinois EPA is confident all significant point sources are included in ISSIS. The Illinois 

EPA also identified sources that were known to have operated in 2011 but which did not 

have their emission data entered into the system by the end of 2011. 

The 2008 periodic emission inventory was used as a comparison for all point emission 

categories in the 2011 inventory. The 2011 area source categories were also checked 

against the 2008 inventory. All area source and mobile source categories listed in the 

federal guidance are included in the inventory. Illinois EPA checks MOVES model 

inputs (particularly temperatures and volatility) and VMT data for completeness, in order 

to ensure their suitable use in the model. 

For area sources, the preliminary 2011 inventory developed by USEPA was used to 

identify additional source categories that may have not been calculated in previous 

years. There were very few categories that were not already inventoried (and some 

were exclusively in the point source inventory) and they were included in the inventory. 

6.5.2 Data Quality 

To ensure the emission inventory is of the highest quality, QA procedures were in place 

for evaluating the quality and reliability of data for use in the inventory. These 

evaluation processes enable the inventory staff to make informed choices between 

sources of information, especially if the data from one source differs significantly in 

comparison with those that were obtained from another source. Also, the evaluation 

process allows the inventory staff and users of the inventory to make informed 

judgments about the validity of the emissions in any particular category. 

Representative QA actions include checking the base year relevancy of the data; the 

use of 2011 data where possible, is emphasized. However, if such base year data are 

unavailable, the most recent reliable data is used and noted accordingly in the inventory 

documentation. 

Data were crosschecked with similar published data. Appropriate caution was taken in 

the choice of “other published data,” especially when such data may have originated 

from the same source that produced the original data. In such cases, the actual data is 

not easily verifiable, but some credibility and support is given for such data, especially 

when an independent organization had chosen to publish such data. Checking 2011 

inventory data against those reflected in the past year or years is useful since 

magnitudes and trends may be verified in this manner. 

Some QA actions were more subjective, i.e., the judgment and experience of the 

inventory staff is important in these evaluations. The professional capabilities and 

biases, if any, of the suppliers of the data were taken into consideration, including the 

purpose for which the data were collected. Data organized by government agencies for 
82

taxation purposes (e.g., gasoline sales) and industry information on purchases and 

sales of materials and products (e.g., coal usage at the power plant), were considered 

of acceptable quality since both entities have a specific incentive to obtain the most 

accurate information. Data collection techniques, if known, were assessed accordingly. 

For example, information from plant inspections was considered more reliable than data 

from mail surveys. However, unless the inventory staff or the QA Coordinator had any 

significant comment about one or more of these subjective assessments (for example, 

when one source of data for a category was chosen over another), such assessments, 

as a rule, are not part of the inventory documentation. 

6.5.3 Emission Estimation Methods 

Illinois EPA estimates emissions following the procedures outlined in these USEPA 

publications: 

· EPA-450/4-88-019, Inventory Requirements for Post-1987 Ozone State 

Implementation Plans, December 1988 

· EPA-450/88-021, Procedures for the Preparation of Emission Inventories for 

Precursors of Ozone: Volume I, Third Edition, December 1999 

· EPA-450/4-81-026d (Revised), Procedures for the Preparation of Emission 

Inventories for Precursors of Ozone: Volume IV: Mobile Sources, July 1989 

· AP-42, Compilation of Air Pollutant Emission Factors, Fifth Edition, January 

1995 and supplements 

Where specific USEPA guidance was not available, Illinois EPA used generally 

accepted engineering principles, calculations, and judgment, supplemented by technical 

information from other sources, in estimating emissions. In all such cases, the method, 

data, and other relevant information were identified accordingly. 

The emission estimates were adjusted to reflect conditions on a typical 2011 summer 

weekday as follows: 

· Point Sources: Emissions were calculated using peak ozone season 

emission rates from source-submitted 2011 AERs. 

· Area Sources: Emissions were calculated using seasonal adjustment factors 

such as those reflected in USEPA guidance and by adjustments for 

representative 2011 summertime temperatures and volatility for certain 

categories (e.g., storage of gasoline and other VOM). 
83

6.5.4 Consistency with Other States 

Several conference calls were held for the 2008 inventory development process with the 

states of Indiana, Michigan, Minnesota, Ohio, and Wisconsin through LADCO to identify 

the emission factors or calculations methods to be used in calculating emissions from 

certain area source categories. There were no significant changes with the 2011 

inventory to warrant additional calls. 

6.5.5 Calculations and Data Handling 

Computers were employed in all calculations for the inventory. Arithmetic errors are 

minimized in these calculations. Typographical errors and incomplete algorithms are of 

concern. For this situation, sample manual calculations were done for comparative 

purposes. At least one such calculation was made for every category. 

Computerized information was stored on the BOA’s network and was backed up nightly. 

Original inventory data continued to be maintained in the database. This data was 

extracted from the database and was maintained in an Access® database on the 

network. The Access® database was manipulated to obtain the 2011 point source 

inventory. 

6.5.6 Validation Procedures 

Point and area sources were also checked against the list of categories shown in the 

QA Guidance to ensure all emission categories were covered. 

· Data consistency: The input and output data are consistent with USEPA 

guidance documents as to the (1) area of coverage, (2) pollutants, (3) 

methodologies, and (4) units of measurement employed. 

· Area covered: This inventory was compiled on a statewide basis. 

· Pollutants covered: Ozone precursors NOx and VOM were inventoried in 

accordance with USEPA guidance requirements. 

· Double-counting of emissions: This could occur in categories which have both 

point and area source emissions represented in the inventory (e.g., the dry 

cleaning category). The category’s point source emissions are assumed to be 

included in the total or gross emissions, which are generally estimated based on 

a surrogate factor such as population. The net area source emissions are then 

calculated by subtracting the calculated point source emissions from the total in 

order to avoid accounting for point source emissions twice. Some other area 

source categories which have the potential for double counting of emission are 

Graphic Arts, Commercial/Institutional fuel use and Waste Disposal. These were 

reviewed to make sure no double counting occurred in the inventory. 
84

· Methods and units used: This procedure ensures the methods of calculations 

employed are consistent with USEPA guidance and usage of such units is 

correct. 

6.6 Data Handling 

6.6.1 Data Coding and Recording 

Coding and recording of data into the ISSIS and CAERS database is done by trained 

inventory staff and is subject to standard operating procedures (SOPs). Similarly, 

updates and corrections discovered in the course of QA efforts were updated by the 

inventory staff. Any changes to the database are monitored and reviewed by the 

Inventory and Data Support Unit Manager. QA of information was further carried out by 

the QA Coordinator before any inclusions were considered into the 2011 inventory. 

6.6.2 Data Tracking 

Illinois EPA keeps its data and calculations mainly on personal computers and/or the 

BOA’s network. Raw data, especially for area sources, are obtained in various forms 

which are kept in files by the inventory staff for future reference purposes. Such files 

may include other information (e.g., sample calculations, estimates, sources of 

information, various relevant notes, and correspondence, etc.) also for reference 

purposes. Any data in electronic form was backed up so that every file is available for 

quick recovery and reconstruction of data. 

6.6.3 Correcting Data 

When an inventory staff member discovers an error in reported data, that data is 

corrected in both the extracted data for the inventory and the originating data source. 

First, the person identifying the error consults with the Inventory and Data Support Unit 

Manager to determine whether a correction is truly necessary. If a correction is 

warranted, the person responsible for maintaining the extracted data is notified on what 

changes to make to that data set. Updates to the originating data set are performed by 

the inventory staff designated by the Inventory and Data Support Unit Manager. 

6.6.4 Missing Data 

This applies mainly to point source data. As noted above, missing emission data was 

not a major problem for Illinois EPA, but point source data have been known to be 
85

missing or in error for many small sources, and their absence, while not affecting 

emission totals, could be significant. For point sources, permit data has been used to 

obtain estimated values for missing data. In other categories, missing data, if they 

occurred, were treated as data needing correction and dealt with accordingly. Where 

any missing data could not be obtained, a note was made of the fact, and suitable 

values estimated. The methods used to estimate the data is documented in detailed 

records. 

6.7 QA Audits 

6.7.1 Internal 

The Illinois EPA did not perform a complete internal or agency QA audit during its work 

on the 2011 inventory. Compilation of the 2011 inventory differs slightly from past 

inventories. USEPA now provides a common set of data (e.g., population, employment, 

etc.) and procedures for use in compilation of the area source component of the 

inventory. The Illinois EPA gave preference to available 2011 data since much of 

USEPA’s data was for 2010. The Illinois EPA also gave preference to data sources it 

had used in the past to maintain a consistent inventory throughout the years. 

A review of the initial data in the point source inventory was compared against the 

annual totals reported on the source’s AER. Sources where the difference was greater 

than 10 tons were reviewed and updated as necessary. 

6.7.2 External 

The 2011 inventory data was required to be submitted to the USEPA by December 31, 

2012. In early February 2013, USEPA was providing some preliminary QA reports to 

the states. Based on the current reports available to Illinois EPA, there does not seem 

to be any significant problems. Most of the issues identified are minor in nature. In fact, 

some of the issues identified by USEPA are items previously identified by Illinois EPA 

that did now warrant corrections (e.g., significant change in emissions from a previous 

inventory). Issues that USEPA found that Illinois did revise in the inventory were related 

to hazardous air pollutants. 

QA reports provided by USEPA will be reviewed and appropriate data will be corrected. 

A letter dated March 4, 2013, to the Bureau Chief from the USEPA identified Illinois 

EPA as having submitted a complete inventory. At this time, there does not seem to be 

a need to change previously calculated emissions or add new area source categories to 

the inventory. 

87

7 Conclusion 

This report summarizes and documents Illinois’ 2011 inventory of ozone precursor 

emissions. This report includes emissions for the entire state, plus identification of 

emissions for the two nonattainment areas of the state and the remaining attainment 

area. The inventory was developed using actual 2011 emissions and data except in 

cases where noted. 

This document presents the 2011 base year ozone inventory for both typical summer 

day and annual emissions for NOx and VOM from point, area, on-road mobile, and offroad mobile sources for the State of Illinois. In producing this document, Illinois EPA 

has followed the procedures outlined in USEPA’s guidance documents pertaining to 

both preparation and quality assurance of the inventory and therefore believes the 

inventory to be complete, accurate, and of high quality.

Nat Geo' s 'Brain Garnes': Think of it as geek TV 

NEW YORK (AP) - Given 

tha t David Rees h as written 

a book on h ow to sharpen a 

pencil. he seems the perfect choice to host a new 

Na tional Geographic 

Channel series that elevates mundane activities 

into the subject of deep 

investigation. 

So, for th ose inclined, 

Rees' "Going Deep" over the 

next two months will tell 

more than you ever thought 

you could k now about digging a hole, tying a shoe, 

m aking ice cubes, s h aking 

hands or throwing a paper 

a irplane . 

The series debuts 

Monday (10 p.m. EDT) following a new episode of 

"Brain Games." It's part of 

what has become a new 

progran1ming genre at 

Na tional Geographic tha t 

explains how the world 

works. Think of 1t as Geek 

TV, alth ough t he network 

works very hard to make 

s hows th at will appeal to 

the channel surfer. 

"Brain Games" st arted it

more abstract; t ests measure compassion, anger, 

addiction and intuition. 

A three-hour "Brain 

Games" s pecial in 2011 did 

so well the network quickly 

ordered a series, which 

became National 

Geographic's most popular 

program, said Courteney 

Monroe, th e n etwork's chief 

executive. 

"It remains unique on t he 

television landscape," she 

said. "That was what k ind 

of tgnited it for us. As we 

watch ed the performa nce 

continue to grow, we said, 

'Wh at else can we get in 

this space?"' 

Other s h ows were 

launched to appeal to the 

same taste. l n "None of t h e 

Above, " host Tim Shaw 

conducts experiments and 

asks people to predict the 

outcome. "Th e Numbers 

Game" uses statistics, role 

play and experimen ts to 

a nswer questions like "are 

you a risk ta ker?" or "can 

you be a hero?" 

One series soon to come, 

"Mind Over Masses," was 

inspired by YouTube clips.

Ca n 't Lick Your Elbow" 

examines the human body. 

"Mapology," du e next year, 

uses data. analysis to 

w 1cover some of the world's 

w1expected reallties. 

Th e network has also 

given the go-ahead to a 

min iseries about inventors, 

"American Geniu s,'' produced by th e same company that made "The Men 

Who Built America." 

It's enough to make the 

brain hurt. 

Monroe needs to ba lan ce 

the in terest in viewers 

unleashed by "Brain 

Games" with oversaturating 

the market, keeping in 

mind that competing networks will surely develop 

copycats. "We're always 

worried about that," she 

said. 

Within the genre, "Going 

Deep" is a little risky, 

Monroe said. Rees is a former political cartoonist a nd 

a comedian who - h onest! 

-maintain s a side business sharpening pencils for 

money. He and the s how 

have an edgy New York wit. 

"He's quirky," Monroe 

said. "The show is quirky. 

The sensibility is quirky. 1 

Francis has exhorted 

priests to buy "humble" cars 

- the pope drives a used 

Ford Focus - and he takes 

his meals in a Vatican refectory. 

With his ordination upon 

him, Kyle Sahd says he "has 

a lot of joy, a lot of anticipation." 

He knows the priesthood 

will have its challenges, especially now, as parish es make 

do with fewer priests. 

He says he looks forward 

to learning from whatever 

pastor h e'll be assisting.

work. I love th at we're trying it." 

As the title suggests. 

"Going Deep" u ses each 

show's question to take 

intriguing side trips. An 

episode on how to strike a 

match delves into the science of fire, which Rees 

finds not as haphazard as 

he thought. He finds a scientist with striking new 

designs for real airplanes to 

talk to on his show a b ou t 

paper airplanes, and is 

s h own glacial ice hundreds 

of thousa nds of years old in 

his ice cube program . 

Producers flew in an expert 

on knots from Australia for 

the shoelace episode. 

"I think that was our 

entire travel budget," he 

said. 

Rees believes his show 

has found the right h ome 

in the geeky corner of 

National Geographic 

Channel. 

"We h ad three networks 

saying, 'We're out there 

looking for a new 'Duck

Notice of Ozone Precursor Emissions Inventory Submittal 

to Update State Implementation Plan 

The Illinois Environmental Protection Agency (Illinois EPA) hereby provides 

notice and opportunity to comment and/or request a public hearing concerning the 

submittal of an Inventory of Ozone Precursor Emissions for 201t. The Illinois EPA 

is required to submit an Inventory of Ozone Precursor Emissions to the United 

States Environmental Protection Agency (USEPA) pursuant to Section t82 (a)·(f) 

of the Federal Clean Air Act (CAA). 

The 2008 Ozone National Ambient Air Quality Standard promulgated by USEPA 

in March 2008 ultimately resulted in the Chicago and Metro-East St. Louis areas of 

Illinois being designated as marginal ozone nonattainment areas in 2012. Sections 

182(a)-(f) of the CAA identify actions necessary by the state when a new nonattainment area is established. For these marginal nonattainment areas, Illinois EPA is 

required to update its State Implementation Plan (SIP) with an inventory of actual 

emissions for all sources of ozone precursors. 

This report summarizes and documents Illinois' 2011 inventory of ozone precur· 

sor emissions for the entire state, plus identification of emissions for the two nonattainment areas of the state and the remaining attainment area. The report presents 

the 2011 base year ozone inventory for both typical summer day and annual emissions for NOx and VOM from point, area, on-road mobile, and off-road mobile 

sources for the State of Illinois. 

In producing this document, Illinois EPA has followed the procedures outlined in 

USEPA's guidance documents pertaining to both preparation and quality assurance 

of the inventory and therefore believes the inventory to be complete, accurate, and 

of high quality. 

Illinois EPA believes that all the requirements regarding the Inventory of Ozone 

Precursor Emissions have been met. This inventory will be submitted for review 

and approval as an update to the SIP and meets the Federal requirements as set 

forth under Title 40: Protection of the Environment, Part 51 - Requirements for 

Preparation, Adoption, and Submittal of Implementation Plans. 

This emissions inventory is not a notice for new rule development or revision of 

existing rules. Any future revisions to existing rules or creation of new rules will follow proper procedures, including public comment and opportunity for a hearing. 

The complete Inventory of Ozone Precursor Emissions can be reviewed online 

at http://www.epa.state.il.us/public-notices/ and at the Illinois EPA offices at 1021 

North Grand Avenue East, Springfield, 2t717S2·7027; 2009 Mall Street, 

Collinsville, 61S/346-5120; and 9511 West Harrison in Des Plaines, S47/294-4000 

(for all locations, please call ahead to ensure that someone will be available to 

assist you). 

The Illinois EPA is accepting comments and requests for a public hearing on the 

Inventory of Ozone Precursor Emissions. Comments and requests for a public 

hearing must be postmarked by midnight, August 11 , 201 4 and mailed to Brad 

Frost, Illinois Environmental Protection Agency, Bureau of Air, 1021 North Grand 

Ave. East, P.O. Box t9276, Springfield, IL 62794-9276 or emailed to 

Brad.Frost@illinois.gov.

Catholic High School for

"It was during th at time 

that I felt God was calling me

tha t for some people, a calling comes as a. lightning bolt. 

"For me, it was more of a

Since his childhood, he 

says, ''It was in the back of

"People see in our pope 

how to live a life that Christ 

wants us to live," Kyle Sa.hd 

says. 

As a diocesan priest. he 

will n ot need to take a vow of 

poverty. But still, he says, 

Francis has called on his 

priests to live simply. 

As he begins h is life as a 

fully ordained priest, Kyle 

Sa.hd says that Pope Francis' 

"words are always going to be

will a lways be in my mind.
