EIQ Form 2.0 Emission Unit Information
Application Instructions for Form 780-1621
7/2009
Air Pollution Control Program fact sheet
A separate form 2.0 is required for each Source Classification Code, or SCC, reported.
The information given should be consistent with the construction permit.
This form must be completed for each reportable emission unit shown on Form 1.1 Process
Flow Diagram, and Form 1.2 Summary of Emission Units and Related Processes. A reportable
emission unit includes 876 pounds (0.438 ton) or more of:
Particulate Matter of 10 microns, or PM
.
10
Volatile Organic Compounds, or VOCs.
Particulate Matter of 25 microns, or PM2.5.
Ammonia or NH3.
2,000 pounds (1 ton) or more of Nitrogen Oxide, Sulfur Dioxide or Carbon Monoxide.
Exceeds Hazardous Air Pollutant, or HAP, thresholds.
HAPs are separated into two groups or categories with different emission unit level reporting
thresholds based on the toxicity of the specific HAP chemical. The first group, Category 1,
consists of a small set of the most hazardous or toxic chemicals that have an annual emission
unit reporting level of 20 pounds or more emitted per year. If a total of 20 pounds or more of
Category 1 HAPs are emitted from an emission unit, then all HAP emissions must be reported
for that unit. All other HAP chemicals are in Category 2 with an annual emission unit reporting
level of 200 pounds or more emitted per year. If a total of 200 pounds or more of Category 2
HAPs are emitted at a unit, then all HAP emissions must be reported for that unit. Also
remember, when reporting HAPs such as PM
or VOCs, the emissions are subject to HAP
10
reporting thresholds.
The authorized facility representative signing the EIQ is responsible for ensuring all submitted
EIQ forms are filled out completely. Incomplete forms will be returned and the Air Pollution
Control Program will note that a complete submittal was not received. Items that clearly do not
apply may be left blank, but all others must be complete. Required items include, but are not
limited to, SCC codes, throughput values, maximum hourly design rates, emission factors,
source and references for emission factors and actual emissions.
All units of measure must be consistent (throughput unit of measure must match the Emission
Factor denominator unit of measure). This is one of the most frequent errors we see and
requires the department to contact you regarding the submission.
Complete the Facility Name, Federal Information Processing Standard, or FIPs, County Number,
Plant Number and Year of Data fields at the top.

Emission Unit Identification
This information should be consistent with the construction permit.
Emission Unit Number - This identification number must match the emission unit identification
number listed on Forms 1.1 and 1.2. The same unit number must be used on any other forms
associated with this emission unit.
Emission Unit Description - This description must uniquely identify the equipment or emission
process that generates air emissions.
Emission Process Detail
Segment Number - This is a two-digit number assigned by the facility used to uniquely identify
processes associated with an emission unit. Generally, if an emission unit, i.e., EP01 has three
processes associated with it, then segment numbers 01, 02 and 03 will be assigned to those
processes. Once assigned, this number should remain constant from year to year. If there is a
change in the SCC used by the facility to identify a process, a new segment number will be
assigned to that process or SCC.
Source Classification Code - This is a required field. This eight-digit code identifies the type of
equipment, process, or material associated with an emission unit. A list of SCCs is available on
the Web at http://cfpub.epa.gov/oarweb/download/WebFIRESCCs.csv.
If you cannot locate a SCC specific for your process, use the SCC most closely associated with
your process.
SCC Description - This is the written description of the unique process from which air pollutants
are emitted. SCC descriptions are available at the Web address referenced above in the
downloadable spreadsheet. Column I, titled SCC_L4 describes the specific emitting process
occurring at the facility.
Emissions flow through stack or vent - If any air emissions created by this emission unit flow
through a stack or vent to the outside atmosphere, check “Yes” and complete a 2.0S form to
detail the parameters for the stack or vent. If no air emissions created by this emission unit
flow through a stack or vent, check “No”, then specify in the following fields that 100 percent
of the air emissions from this unit are fugitive.
Fugitive Emissions - If any of the air emissions from this emission unit are fugitive or not
released to the ambient air through a stack or vent, check “Yes” and enter the percentage
of the total emissions from the unit that are fugitive.
Operating Rate/Schedule
Annual Throughput - The amount of material used, processed or produced in the process
associated with the emission unit during the calendar year.
Annual Throughput Units - Report the unit of measure of the annual throughput.
Hours/Day - The annual daily hours the equipment or process associated with the emission unit
was in operation.
Days/Week - The annual weekly days the equipment or process associated with the emission
unit was in operation.
Weeks/Year - The number of weeks per year the equipment or process associated with the
emission unit was in operation.
2
Total Hours Per Year - The product of the Hours/Day, Days/Week and Weeks/Year. It will
®
automatically be calculated if you are using the Excel
file format.
Dec-Feb(percent), Mar-May(percent), Jun-Aug(percent), and Sept-Nov(percent) -
For each of the four quarters, which have been adjusted to conform to EPA standards, specify
the percentage of total annual throughput attributable to each quarter. Estimates are acceptable.
The entries for all four quarters must total 100 percent. Each month here is within the reporting
year, so the first quarter will be January, February and December of the reporting year.
Annual Fuel Characteristics
If coal or fuel oil was used for fuel, complete the Heat Content, Ash Content and Sulfur Content
fields. Ash content and sulfur content were separate fields included in the emission calculation
that occurs below in section 5 in previous years. Beginning with the 2008 emission reporting
year, the specific ash or sulfur content will be listed in section 4, and the emission factor column
in section 5 should reflect the total emission factor for units burning coal or fuel oil and using an
emission factor based on a formula.
Example: Emission factor is the result of 39*S, and assuming sulfur content of 2 percent, the
emission factor will be 39*2 = 78.
Emissions Calculations
Source of Emission Factor - Choose from the list in the right column.
Emission Factor - This is the relationship between pounds of pollutant emitted per one unit of
throughput. Example emission factors would be 100 pounds of NO
emitted per million cubic
x
feet or MMCF of natural gas burned, 15 pounds of VOC emitted per gallon of paint applied, or 3.5
pounds of PM
emitted per Vehicle Mile Traveled, or VMT.
10
Emission Factor Control Status - This is a commonly misunderstood box, resulting in many
errors. This field refers to the status of the factor itself, and determines how the emission
calculation formula will work
• If the emission factor itself is net of control, this is C. The emission calculation formula
will not be reduced a control efficiency value because the factor already accounts for
the control reductions.
• If the emission factor itself is not net of control, this is U. The emission calculation formula will
include the control efficiency reduction.
• If a control device is being used, the factor can be either controlled (C) or uncontrolled (U). If
there is no control device, the factor used must be U.
Overall Control Efficiency (percent): An overall control efficiency for each class of pollutant
will be determined using the following formula:
Overall Control Efficiency for x = (CP x CE
) ÷ 100
x
Where:
x
= Class of pollutant (PM
, SO
, NO
, VOC, CO, Lead or HAP)
10
x
x
CP
= Capture Efficiency of the Control Device
CE
= Control Efficiency for that Class of Pollutants
x
3
A pollutant should have an overall control efficiency only if there is a control device listed on
Form 2.0C and the device controls that particular class of pollutants and the control efficiency
has not been included in the emission factor.
Example: A control device has a Capture Efficiency of 50 percent, and destroys 75 percent of
the VOCs it captures.
CP = 50%, CE
= 75%
VOC
Overall Control Efficiency for VOCs = (50 x 75) ÷ 100
= 3,750 ÷ 100
= 37.5 %
Multiple Control Devices - If more than one control device applies to the same pollutant at an
emission unit, the combined overall control efficiency needs to be calculated. This can be done
several different ways, depending on the configuration of the control devices.
• If each control device has its own separate intake, then each control device will use its own
capture efficiency.
• If the control devices are in series, the capture efficiency of the first device in the series is
used to determine the overall control efficiency for the entire series. To determine the Overall
Control Efficiencies for devices in the series, use the following formula. If using the Excel
spreadsheet, it will calculate the series’ Overall Control Efficiency.
Combined Control Efficiency = {CE
+ CE
- [(CE
x CE
) ÷ 100]} x CP
/100
1
2
1
2
1
Where:
CE
= Control Efficiency for First Device in the Series
1
CE
= Control Efficiency for Second Device in the Series
2
CP
= Capture Efficiency for First Device in the Series
1
When two devices in the series are used to remove the pollutant PM
from the same
10
emission unit, the control efficiencies must be combined.
Example: If the first device has a capture efficiency of 75 percent and a control efficiency of
50 percent for PM
and the second device has an efficiency of 80 percent for PM
, the
10
10
calculation of combined efficiency is as follows:
Combined Control Efficiency = {50 + 80 - [(50 x 80) ÷100]} x (75 ¸ 100)
= {130 - [4,000 ÷ 100]} x 0.75
= {130 1 - [40]} x .75
= 90 x 0.75
= 67.5%
Thus, the combined control efficiency for PM
at this emission unit would be 67.5 percent.
10
• If control devices are in a configuration other than the two listed above, you may provide
documentation for your facilities’ control devices. This documentation should show your
calculations for the overall control efficiency for each class of pollutant at this unit.
If you have any questions call the Air Pollution Control Program at 573-751-4817.

Actual Emissions (tons/year) - If you are using the Excel spreadsheet versions of Form 2.0,
actual emissions will be automatically calculated based on the throughput, emission factor,
emission factor control status and overall control efficiency provided. If you have measured
the emissions, you will need to back calculate or use Goal Seek to determine the correct
emission factor.
The actual emissions are the amount in tons per year of the pollutant emitted at the emission
unit described. All figures should be rounded to two decimal places. Use the following formula:
Actual Emissions =
Annual Throughput x Emission Factor x
[(100 - Overall Control Efficiency) ÷ 100] ÷ 2,000.
Example: Assume the annual throughput is 30,000 tons of grain processed, the PM
10
uncontrolled emission factor is 0.91 pounds of PM
emitted per ton of grain processed and a
10
PM
control device for this emission unit has an efficiency of 90 percent.
10
Using the formula above:
Actual Emissions = 30,000 x 0.91 x [(100 - 90) ÷100] ÷ 2,000
= 27,300 x [10 ÷ 100] ÷ 2,000
=
27,300 x [.1] ÷ 2,000
= 2,730 ÷ 200
= 1.37 tons of PM
emitted per year
10
Enter 1.37 in the PM
box in column (5), Actual Emissions, on Form 2.0.
10
Note: If no control devices were used, the Control Efficiency equals 0% and the annual PM
10
emissions would be 13.65 tons.
Actual Emissions =
Annual Throughput x Emission Factor x
[(100 - Overall Control Efficiency) ÷ 100] ÷ 2,000.
