5.2 Procedure 

Category 1: Stationary Fuel Combustion 

Sub-Category 1.1: Industrial Fuel Combustion 

SCC: 2102002000, 210200400, 2102005000, 2102006000, 2102007000 

Follow these steps when calculating emissions from industrial fuel combustion: 

1. Obtain statewide fuel consumption for “Other Industrial” for the following fuels: coal, distillate oil, 

natural gas, and liquefied petroleum gas (LPG). Use the Energy Information Administration’s website 

at http://www.eia.doe.gov/ to find fuel consumption. 

Note: As of the date of this SOP, the following steps will lead to data for fuel consumption. 

a. Go to http://www.eia.doe.gov/

b. Click on link for the various types of fuel consumption 

c. Click on consumption tab for state totals 

2. To avoid double calculating the various fuel combustions, subtract reported source totals from the 

total statewide fuel consumption by querying the total process rates for the various SCC codes using 

the ACCESS data tables at K:\OAQ_INV\Steptool\Stptl_02.mdb. The remaining number is the area 

source fuel consumption for the state. 

3. To distribute the remaining fuel to the county level, calculate the ratio of county to state employment 

for the manufacturing sector by dividing the number of Manufacturing Employees for each county by 

the number of manufacturing employees statewide. Use the County Business Patterns website at 

http://www.census.gov/ to find the number of manufacturing employees for each county. 

Note: As of the date of this SOP, the following steps will lead to data for Economic Census. 

a. Go to http://www.census.gov/

b. Click on Economic Census 

c. Under 2002 Reports by State, use the down arrow key to select Indiana 

d. Now, select each of the counties to find the county manufacturing employees 

e. Use the total of employees for manufacturing under the paid employees’ column 

4. Multiply the ratio calculated above in step 3 by the area source fuel consumption to distribute the fuel 

to the county level. The remaining number is the process rate for each county. Multiply the process 

rate by the appropriate EPA emission factors for the various fuels for industrial manufacturing found 

in AP-42, Fifth Edition, Volume 1, Chapter 1, External Combustion Sources at 

http://www.epa.gov/ttn/chief/ap42/ch01/. 

Sub-Category 1.2: Commercial/Institutional Fuel Combustion 

SCC: 2103004000, 2103005000, 2103006000, 2103007000 

Follow these steps when calculating emissions from commercial/institutional fuel combustion: 

1. Obtain statewide fuel consumption for “Commercial” for the following fuels: distillate fuel oil, liquefied 

petroleum gas (LPG), natural gas, and residual fuel oil. Use the Energy Information Administration’s 

website at http://www.eia.doe.gov/ to find fuel consumption. 

Note: Use the steps in sub-category 1.1-1 to navigate through the Energy Information 

Administration’s website.

Area Source Inventory 

S-006-OAQ-R-MO-08-S-R1 

2. To avoid double calculating the various fuel combustions, subtract reported source totals from the 

total statewide fuel consumption by querying the total process rates for the various fuels using the 

SIC codes greater than 4999 using the ACCESS data tables at K:\OAQ_INV\Steptool\Stptl_02.mdb. 

These are the SIC codes that identify all the commercial/institutional area sources. 

3. To distribute the remaining fuel to the county level, calculate the ratio of county to state employment 

for the commercial/institutional sector by dividing the number of commercial/institutional employees 

for each county by the number of commercial/institutional employees statewide. Use the County 

Business Patterns website at http://www.census.gov/ to find the number of commercial/institutional 

employees for each county. 

Note: Use the steps in sub-category 1.1-3 to navigate through the U.S. Census Bureau’s website. 

4. Multiply the ratio calculated above in step 3 by the area source fuel consumption to distribute the fuel 

to the county level. The remaining number is the process rate for each county. Multiply the process 

rate by the appropriate EPA emission factors for the various fuels for commercial/institutional found in 

AP-42, Fifth Edition, Volume 1, Chapter 1, External Combustion Sources at 

http://www.epa.gov/ttn/chief/ap42/ch01/. 

Sub-Category 1.3: Residential Fuel Combustion 

SCC: 2104002000, 2104004000, 2104006000, 2104007000 

Follow these steps when calculating emissions from residential fuel combustion: 

1. Obtain statewide fuel consumption for “Residential” for the following fuels: coal, distillate oil, natural 

gas, and liquid petroleum gas. Use the Energy Information Administration’s website at 

http://www.eia.doe.gov/ to find fuel consumption. 

Note: Use the steps in sub-category 1.1-1 to navigate through the Energy Information 

Administration’s website. 

2. To distribute residential fuel to the county level, calculate the ratio of county fuel usage to statewide 

fuel usage using the breakdown of fuels by household per county divided by the breakdown of fuels 

by household per state using the U.S. Census Bureau’s website at http://www.census.gov/ . 

Note: As of the date of this SOP, the following steps will lead to data for breakdown of fuels by 

household. 

a. Go to http://www.census.gov/

b. On the left hand side click on “American Fact Finder” 

c. Using the drop down menu, click on Indiana 

d. Scroll to “Housing Characteristics” and select “show more” 

e. On the left hand side, select “change geography (state, county, place...)” 

f. Using the drop down menu, select county, state, and each county name to obtain housing 

information 

3. Multiply the ratio calculated above in step 3 by the area residential fuel use by state to distribute the 

fuel to the county level. The remaining number is the process rate for each county for the various 

fuels. Multiply the process rate by the appropriate EPA emission factors for the various fuels for 

residential found in AP-42, Fifth Edition, Volume 1, Chapter 1 External Combustion Sources at 

http://www.epa.gov/ttn/chief/ap42/ch01/.

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.

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.

Figure 3. Base year emission plots for Canada

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.

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 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

 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.

February 27, 2008

• 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.

February 27, 2008

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.
