1 Initial Pre-Reporting Steps
1.1 Software Requirements for CAERS
To use the CAER system, you will need:
• Internet browser and connectivity: This should be a recent version of any internet
browser such as Chrome, Explorer, or Firefox. Your internet connectivity will determine
how fast data can be uploaded.
• Microsoft Excel: Bulk uploads will be in "XLS" or "XLSX".
• Optional for bulk upload: If you would like to upload your file in JavaScript Object
Notation (JSON), send an email to caer@epa.gov with subject line "CAERS JSON Upload".
1.2 Pre-Login Steps for GA Facilities
Your process will begin by logging into Georgia Environmental Connections Online (GECO). GECO
will guide you through questions to determine your opt-in status to report to the Emissions Inventory
(El). Once you have opted in, you will be redirected to the CAER system from GECO. This process is
outlined in what follows. Please note that if you have not updated your preparer and or certifier contact
information, you should reach out to GA DNR to do so before going through this process, and you should
have received a registration email.
After logging into GECO you will be taken to a screen to begin your emissions inventory process. Click
on the "Begin 2019 El" button (Figure 1). You will be redirected to a facility information page where
your facility information can be reviewed. Figure 2 and Figure 3 show the top and the bottom of the
facility information page respectively.

1.3 Logging In
In order to enter CAERS, you will need to be registered in EPA's Central Data Exchange (CDX). In
order to do so, even if you already have a CDX account, you should go to the registration email you
should have received if you are a current preparer/certifier. If you have not received the email, you
should reach out to GA DNR to update your contact information, so the email can be sent to you. Follow
the instructions for registration from that email. If you are both an authorized certifier and preparer,
you do not need to do the process twice, just register as both in CAERS once you are in.
In CDX, at the login page enter your credentials. CDX forces users to change their password every 90
days, so make sure you have your most recent password available to you. Once you've entered your
login and password, you will be taken to your "My CDX" page (Figure 8).
Next to "CAER: Combined Air Emissions Reporting" select your role, "Preparer" or "Certifier". This will
take you to the application, where you can review your facility's data and begin/continue reporting from
"My Facilities Page" (Section 1.4). if you are both a preparer and a certifier, you'll need to use this page
to switch between roles. You can go back to your "My CDX" page from within the CAER application by
clicking on the "MyCDX" link at the bottom of the screen. Note, however, that if the preparer and
certifier are the same person, you need only be registered as a certifier, as the certifier will be able to
act as preparer as well.

1.5 Reviewing Facility Data
If you select the "Review Facility Data" button, you will be taken to a separate page that contains
general information about your facility, together with a map of its location. New functionality will be
added to this page in future versions of the CAER system.
2 Reporting Emissions and Facility Information via the User Interface
2.1 Navigating the User Interface
2.1.1 General Description of User Interface Features
While the User Interface (Ul) has many pages and data entry points, there are some common
themes throughout the Ul. This list will help you understand the general layout of the Ul and its
characteristics. Specific features are explained in more detail, including screenshots, in subsequent
sections and are not duplicated here to avoid repetition.
General features (refer to Section 2.1.3, Figure 12 and Figure 13):
• Breadcrumbs at the top of the screens displaying the path that got you to the current screen
from previous screens
• Submission steps bar at the top of the screen that indicates what step you are on in the
submission process
• A menu of links to different facility and emissions data pages on the left-hand side of the screen,
that will help you find the relevant screens to view and enter data. Where multiple units exist,
the menu can be expanded and collapsed.
• Link to "MyCDX" at the bottom of the screen.
• Link to "Help" at the top right of your screen that takes you to a page containing the help desk
contact information and additional resources.
Data entry features:
• Organization of data in each screen in boxes. For example, facility information that is organized
in the following boxes: Facility Information, Facility North American Industry Classification
System (NAICS) Codes, Contact Information (Section 2.2.1, Figure 14). Greyed out data entry
boxes indicating where data is not expected to be changed by the user (Section 2.2.1, Figure 15,
for example).
• Drop down menus in some of the data entry boxes to assist the user in entering the relevant
data without errors (Section 2.2.1, Figure 15, for example).
• Pop-up windows directing the user to make a choice or enter specific information related to the
page the user is in (Section 2.2.1, Figure 15 and Figure 17, for example).
• Data entry quality checks (warnings in purple, critical errors in red) to help the user to address
issues and corrections before submission (Section 2.2.2, Figure 20, for example)
• "Trash can" icons to delete specific sub-facility components. These are not be used when that
component existed in a previous submission. If data was entered in error during the current
submission, the trash can should be used. If the data existed in a previous submission, then the
13
-------
component operating status should be changed to temporarily or permanently shut down (as
the case may be), and the year of that change should be recorded as well.
• Edit icons next to sub-facility components on screen lists to indicate the user can edit them from
the screen the user is in.
• Process of adding sub-facility components. These must be added first before they can be
associated with other components. When a component is added, the associations won't show
up on the screen for that component until the component information has been filled out and
saved (for example, compare screens for Figure 20 and Figure 21). Then, the component page
can be opened and boxes for the associations will appear.
2.1.2 Emissions Reports Page
From "My Facilities", click on Begin/Continue Reporting. This will take you to the "Emissions
Reports" page (Figure 12), where you can see all the reports for that facility. The CAER system will have
your last submission from a previous year's report, and it will allow you to begin a new report for the
inventory year you are reporting.
In order to start or continue a new report click on "Create New Report" or "Continue". You will be re-
directed to the facility "Report Summary" page. If you are using bulk upload to enter your report, refer
to Section 3. However, because there are some new features to annual reports with respect to how
controls information should be entered, you should refer to Section 8 before beginning a report or
working on a submission via bulk upload.
If you begin your current inventory year report and find that you wish to delete it to start over, you can
do so by clicking on the garbage can icon. Once you have deleted it, the "Create" link will re-appear, and
by clicking on it, you will be able to carry forward your previous year reported data to help you get
started. Be aware that deleting any previous year reports already in the system may cause you delays in
re-instating that data if you later realize that deletion was an error. Also, at this time, you will not be
able to re-submit a previous year report for a previous reporting year.

Run Quality Checks
You will see breadcrumbs in the dark blue bar at the top of the screen. These display the path that got
you to the current screen from the "My Facilities" page. By clicking on any of the links, you will be
returned to a previous page. For example, from "2019 Emissions Report" you can click on "Emissions
Reports" to be taken back to that page.
Below the breadcrumbs, at the top center of the screen, you'll see a bar showing the four main steps of
submission that will help guide you through the submission process:
• Report Facility & Emissions Information,
• Perform Quality Checks,
• Submit to SLT (your State, Local, or Tribal) Authority, and
• Approved by SLT Authority.
On the left-hand side you will see an expandable menu with links that will take you to different pages:
• Report History (shows a list of actions associated with the report over time and who performed
them, for example, when it was created, submitted, whether the SLT has approved it).
• Quality Assurance (QA) Checks (takes you to the list of QA checks that your report, as it stands,
is currently generating) see Section 4.
• Facility Inventory data (with summary pages at different levels of detail: facility information,
emissions units, release points, control devices, control paths) see Section 2.2.1.
• Emissions Inventory (a collapsible list of units that you can expand to view the processes
associated with each unit) see Section 2.3.
16

You will be able to edit facility information by clicking on the "Edit" button at the far right, which will
take you to the facility information edit page (Figure 15). Note that fields that have been locked will not
be editable. They will appear in gray. You should contact your SLT authority (for example, GA DNR) if
you think there is an error in locked fields. A gray arrow within a data field box indicates a drop-down
menu is available to choose your entry.
If the facility operated partially in the reporting year and was permanently shut down in the reporting
year, you wiil need to leave the "Operating" status unchanged for the year you are reporting, and
change it the following reporting year. Once you change the operating status to "Permanently
Shutdown", all units, processes, controls and release points will also be automatically set to
"Permanently Shutdown", and you will no longer be able to enter data for the facility. For example, if
the facility was operated in part in 2019 and shut down for the rest of 2019, you would change its status
to permanently shut down in 2020.

Under the "Facility Information" box, you will be able to add a NAICS code. More than one NAICS are
allowed as secondary NAICS codes, but a single NAICS should be designated as the primary NAICS code.
When you click the "+" button at the bottom right of that box, a pop-up window will appear to help you
search for your NAICS (Figure 16). Type the digits of your NAICS and a menu for the NAICS that contain
those numbers will appear to help you select the correct code (Figure 17). Once you've selected your
NAICS, click the "Submit" button. If you have questions about NAICS you can reference the U.S. Census
Bureau. NAICS change every 5 years. At the time this document was written, the codes being
referenced were from 2017
Below the NAICS code box, you should find the "Facility Contact Information" box(es). You can enter as
many contacts for the facility as you need. Click on the "Add Facility Contact Information" at the bottom
right of the screen to open a window to enter new facility contact information (Figure 18). Enter all
relevant information such as name, number, and make sure to select a "Contact Type".

2.2.4 Control Devices Page
Control devices will be reported differently than in previous years. Section 8 in this document
explains the concepts surrounding controls. You should familiarize yourself with that section before
proceeding to set up your facility's controls.
From the left-hand side menu, click on "Control Devices" under the "Facility Inventory" heading. You
will see a list of control devices associated with the facility (Figure 27). Previously reported control data
will appear for your facility, unless previously reported controls were marked as obsolete in your last
report. However, you will need to review the data and edit it to reflect your controls in the new
26
-------
framework. You should start by deleting any controls that are duplicated. Then, add any controls that
are missing from the list.
To add a new control device, click on the "+" sign at the bottom right of the list of controls. This will
take you to a blank control page. As with other sub-facility components, drop-down menus are available
for fields that require a selection. For example, to select the operating status click on the gray arrow

Note that the control ID for each individual control must be unique within the facility. On the control's
page, you will add the percent captured and the percent effectiveness. Add all relevant information, QA
check messages will appear for data fields that are required, for value ranges (for example, percentages
must be greater than zero and less than 100%), and for other errors. Click on "Save" to add the new
control to the list of existing controls. If you find you have started to enter a new control in error, you
can click "Cancel" to avoid saving the changes, and you will be returned to the "Control Devices" page.
Now that the control has been added to the list of controls, you can edit it. In addition, you will be able
to add pollutants controlled by the device from that control's information page. Also, when you
associate the relevant pollutant with a control, you will add the percent control efficiency for that
pollutant. Resources to find out information about your control equipment capture and control
efficiency can include vendor specifications, and trade associations that may be able to provide you with
averages for the industry. However, you should consult with staff at GADNR with your questions about
controls and your planned approach to make sure they approve of it before you have submitted the
data. Note that the overall percent controlled, as described in Section 2.3.2.2, will be the value factored
27
-------
into the emissions calculations when the calculation method calls for its application. For example, the
overall control % will not be applied to your calculations if you are reporting stack test data.
To edit a control device or add controlled pollutants, click on that control device's ID from the list of
controls in the "Control Devices" page. This will take you to that control device's information page
(Figure 29).

To associate a pollutant with this control device, click on the "+" sign at the bottom right of the "Control
Pollutants" box. You will be taken to a pop-up window that will allow you to select a pollutant. Start
typing the name of the pollutant or its abbreviation (for example, PM) and a list of possible pollutants
will appear for you to make your selection(Figure 31). When you have chosen the pollutant and entered
the control efficiency (percent reduction), click "Save" and you will be returned to the control device's
information page. Now, the pollutant you entered will appear in the list of pollutants.
29
-------
You will enter the percent reduction efficiency of the control when you enter the pollutant. However,
for version 1 of CAERS, this percent efficiency will not be used directly in the calculation of emissions.
Rather, the overall % efficiency you enter when calculating emissions will contain the percent efficiency
as described in Section 2.3.2.2). Even though only the overall % efficiency will be used for the
calculations, the data you have entered for each control in version 1 will be ready for your submissions
in later versions of CAERS in future reporting years, where the calculations on controls will be done by
CAERS.
Also note that the page for each control device also shows the control device assignment list. The
Control Device Assignment box will show the components that are related to the control. For example,
it will show the release point, emission unit, and emission process that are used by the control. You
have the ability associate the control with these components through the Control Paths page (section
2.2.5). Also note that if the control device is being retired, you must go into the screen for that control
device by clicking on the control ID from the list and change its operating status to "Permanently
Shutdown".

2.2.5 Control Paths Page
Control devices will be reported differently than in years prior to the 2019 inventory year, and
this includes associating controls with specific paths. Section 8 in this document explains the concepts
surrounding controls and control paths. You should familiarize yourself with that section before
proceeding to set up your facility's control paths. A path can include one or more controls as well as
another path.
30
-------
From the left-hand side menu, click on "Control Paths" under the "Facility Inventory" heading. You will
be taken to the control paths page (Figure 32), where you will be able to see a list of control paths
associated with that facility. If this is your first time reporting paths, you will not see any paths
displayed, and you will be creating paths and populating that list from this screen.
To add a new control path, click on the "+" sign. This will take you to a blank path page (Figure 33). You
will be asked to enter a Path ID, which should be unique within the facility, and a brief description to
help identify which path it is. Click "Save" and this will take you back to the Control Paths page. Now
your new path will appear in the list of existing paths and you will be able to edit it.
As you create paths, keep in mind that while one path may contain other paths, ultimately, you will
want to ensure that you've created a path that includes all controls leading from a process to a release
point. Each relationship between an emissions process and a release point (i.e. the release point
apportionment) can only be associated with one control path. All processes from a unit to a release
point can share the same path.

The next step is to add control devices and paths to each new path. To do this, click on an existing path
from the "Control Paths" page. This will take you to that path's information page (Figure 34). On the
bottom right of the "Control Path Assignment" box, click on the "+". This will take you to a pop-up
window that will allow you to include a control or another path in this path (Figure 36).
Enter the sequence number for it. For example, if it is the second control device in the path you will
enter 2. Next, enter either a control device or a control path (you must select one or the other, but not
attempt to enter both a control and a path here). Drop-down menus will allow you to select either an
existing control device or an existing path. You must enter the controls first, so they will appear in the
corresponding menu. You must build smaller (children) paths first, before building larger (parent) paths
that contain the smaller paths.

Enter the control apportionment percentage. For example, if the control device or path you have
selected will be first in the sequence and will be receiving 100% of the emissions from the emissions
process, you would enter 100, If a control receives all emissions from the previous control device or
path in the sequence, enter 100. If the control will be receiving 50% of the emissions from the previous
control or path in the sequence, enter 50. Click "Save" to go back to that path's screen. Your
assignment should appear in the list of assignments.
Here is an example of how data would be entered for a facility with complex controls (see the example
facility in Section 8, (Figure 59). For the example facility, controls are configured as shown in Figure 37.

Additionally, Control Device 1 sends 60% of its emissions to Path 1 and 40% of its emissions to Control
Device 3. Controls 2 and 4 are configured in sequence, and would be added to Path 1 from Path l's
screen as shown in Table 1. In Path 2, Path 1 and Control 3 run in parallel and thus, have the same
sequence number. Path 2 would include the following as shown in Table 2 where Path 1 and Control 3
have been highlighted.

To associate the control path to one or more processes and release points, select the relevant unit from
the "Emissions Inventory" menu on the left-hand side or from the list in the "Emissions Unit" page under
"Facility Inventory". Then, choose the relevant process for that unit that you want to associate and
follow the instructions in Section 2.3.2 on how to associate a release points with processes.
2.3 Emissions inventory
The left-hand side menu of the application shows a list of units for the facility under "Emissions
Inventory". You can click on the arrow to the left of the Unit ID to show a list of processes associated
with that unit. Click on any one of those units or processes to show the unit's information.
2.3.1 Units
Click on the unit you are interested in. This will take you to that unit's information page. Click
on the "Edit" button at the top right of the screen to make changes to the emissions unit information.
For more information on adding or editing a unit, see Section 2.2.2.
2.3.2 Processes
From the left-hand side menu, click on the relevant unit. Once you are in that unit's information
page, you will be able to add or edit a process. To add a process, click on the "+" at the bottom of the
list of processes in the "Processes Associated with this Emissions Unit" box. This will take you to a
process page (Figure 38) where you can enter all relevant information for that process. Drop-down
menus will assist you in selecting some data fields. Error messages will appear for items that have been
entered incorrectly or for missing fields that are required.

Note that your process Source Classification Code (SCC) can be found via search. Click on the "Search
for SCC Code" button and enter a search term (for example, boiler). The search will be performed and
return a list of options for you to choose from. Click on the SCC you want to use. Note that the SCC
Level descriptions for that code will pre-populate in the SCC Description box. You may also enter an SCC
if you already know it (for example, 10100201). See Figure 39.
The form will crosscheck that the code you are entering is a valid point source code and is a code that
has not been retired before the inventory year you are reporting. A warning will be displayed if the
selected SCC is being retired the year of your report, or in the future, but you will still be able to use that
code. However, if the SCC you select was retired before the year of your report, you will see a critical
error. If you want to see a full list of codes or perform different searches, go to https://epa.gov/scc.

Once you add a process, it will appear in the list of processes associated with that unit on the unit's
information page.
From the unit's information page, you can also edit a process. Click on the process you want to edit.
This will take you to a page with all the information about that process (Figure 40). Click on the "Edit"
button at the top right of the screen to make changes to the process information (Figure 41).
Similarly, you can also edit operating details and reporting period information by clicking on "Edit" in
each of those boxes. Note that Version 1 of the CAER System is for annual reporting only. Future
versions of the system will offer more reporting periods. Click "Save" when your edits are finished. Click
"Cancel" if you find your edits are an error and wish to discard them.
From a unit's page, you should only delete a process using the garbage can icon if you added it to this
year's report and that addition was an error. If the process existed in a previous year's report, and is no
longer in use, you can click on its ID and change its status from "Operating" to "Permanently Shutdown".
Once you have done so, the data on the operating details and reporting period for that process will be
hidden from view. However, the "Release Point Apportionment" and "Controls Associated with this
Process" will remain.
When throughput for a process is changed, the CAER system will automatically calculate the emissions
for all pollutants associated with the process, where this is possible. A message in a green box will
appear at the top right of the screen indicating that calculations were successful. If a calculation is not
38

possible, an orange or red box will appear with an error message indicating the problem encountered
with the calculation.

2.3.2.1 Associating a Process to a Release Point
Go to the process information page (Figure 40). You can get there by clicking on the
corresponding unit from the left-hand side menu, and then clicking on the relevant process ID. First, in
the "Release Points Associated with this Process" box, click on the "+" sign to add a release point
associated with the current process. A pop-up window will appear requesting information about the
release point, the control path (optional), and the percentage of the process' emissions being directed
to that release point (Figure 42).
If there are not controls between the process and a release point, you do not have to enter a control
path. You will simply apportion the corresponding emissions to the release point.
If there are controls to associate the control path to one or more processes and release points, you
should associate them here. Note that the control and path assignments should have been defined
before attempting this step (Sections 2.2.4 and 2.2.5). This will allow you to select from existing release
points, and control paths. All emissions from the process must be apportioned to a release point so that
100% of total emissions have been assigned to one or more release points.
40
-------
Figure 42. Release Point Apportionment
After entering the relevant information, click "Save". Now you will be able to see, in the "Controls
Associated with this Process" box at the bottom left of the screen, the path you have associated with
the release point and process.
You will not be able to edit the controls associated with the process from this page. If you need to edit
the controls and/or paths, you must ensure you have entered the relevant control devices and their
paths as in the steps described above, and that you have associated them to the relevant process.
2.3.2.2 Entering and Calculating Emissions
In the page for that process, go to the "Emissions Associated with this Process" box in the lower
left side of the screen (Figure 43). Click the "+" sign to add emissions. This will take you to a new
pollutant page. In the "Pollutant" data field start typing in the name, code, or CAS number. The form
will assist in finding the name of the pollutant. Once you have found the pollutant you are looking for,
select it. The form will then prepopulate the other pollutant data fields: Pollutant Code, Pollutant
Name, and CAS ID if it exists. For example, typing in sulfur will render Sulfur Hexafluoride - SF6, and
Sulfur Dioxide - S02-9-5-7446. Note that some pollutants, such as Volatile Organic Compounds (VOC)
do not have a CAS number because they are groups of pollutants, as opposed to single pollutants. You
will still be able to select such pollutants even if the CAS number field appears blank.
EPA augments triannual reports to reflect Hazardous Air Pollutants (HAPS). Alternatively, if you
wish to reflect your own HAP calculations instead of EPA's, you will be able to do so by entering your
own HAP data when entering pollutant emissions (see Section 2.3.2.2).

Next, select calculation method from the drop-down menu. The form will require the user to enter
specific data fields according to the calculation method selected. If you have selected a USEPA Emission
Factor, the form will allow you to search for an emission factor by clicking on the corresponding box
under the calculation method.
Figure 44. Selecting a Calculation Method
Note that some factor searches will return formulas. The form will require the user to then supply
additional parameters for that formula. For example, sulfur content %. If the emission factor units of
measure (UoM) is different from the throughput UoM's, the form will return an error. However, the
form will perform a simple conversion for units of the same kind (for example, weight UoM conversions
from lbs to tons). See Section 9.3.2 for more information on conversions in CAERS. After entering all
required fields, click on "Calculate Emissions" and the form wili calculate the emissions for you. A green
42
-------
confirmation message at the top right of your screen will appear to indicate the calculations have been
performed. Click "Save" to be taken back to the emission unit information page.
If you have selected an EPA emission factor because one exists but the UoM conversion is not
straightforward (i.e. the emission factor is in tons but the throughput is in hours), you can click the box
"I prefer to calculate the total emissions of this pollutant" located under the Emissions UoM box, and
the calculator will disengage. If you disengage the calculator, you must enter a description of your
calculation process in "Description of Calculation" box to justify the use of an alternative emission factor
or total emissions you calculated (Figure 45).
If controls are present (associated with this process via a path), enter the overall control efficiency for
the path in the "Overall Control %" box. For a single control this is equal to the multiplication of:
(percent capture) x (percent effectiveness) x (percent efficiency). For more than one control (including
control paths) it is the total percent of the pollutant that is removed by the controls (or control paths).
You should reach out to GA DNR if you have questions about how to calculate this value for your specific
controls configuration. For a numerical example on controls, see Section 9.3.5.
Note that your previous system may have rounded the emission factor and/or emissions totals. In that
case, re-select or re-enter the rounded values to eliminate rounding.

For any estimation method that does not involve an emission factor, you will be required to enter a
comment. You may enter "None" or "NA" if no comment is needed or you believe entering a comment
is not applicable. However, for the method "Engineering Judgement" you should always enter an
explanation as to how you arrived at your emissions estimate. You may also attach a file with an
explanation. You should write "See file attachment: " and the name of the file in the "Explanation of
Calculations" box.

3 Reporting Emissions and Facility Information Using Bulk Upload
3.1 The Bulk Upload Template
If you will have relatively few changes between your previous year report and your current year
report, we encourage you to use the user interface instead of bulk upload because this may be more
time saving for you. If you chose bulk upload, you will be able to use it to upload all your data into the
system. There is a special template for bulk upload in Excel format. You should use extreme care when
entering data into the spreadsheet making sure you have not created an error in the template
inadvertently. You should familiarize yourself with this section of the instructions before attempting to
use the bulk upload feature. Also, tips and tools for data entry that have been explained in the User
Interface portion of this guide (Section 2) will be helpful.
For CAERS Version 1, new facilities will be provided a template by GA DNR. Facilities that have reported
in previous years will be provided a pre-loaded template file with their previous year annual emissions
(National Emissions Inventory) report. We strongly recommend that you make a copy of that pre-
loaded template and work with the copy, in case you need to revert to the original.
When you open your file, if a yellow bar appears at the top asking if you want to enable content or allow
edits, click on the button provided to enable content or edits. Once you have your Excel file template
open, you should enter your edits into this file, to reflect the current year submission data.
The template contains several tabs (Figure 46). There are two sets of tabs:
Data entry tabs are highlighted in blue. Each tab contains specific types of data to be submitted. Drop-
down menus help you avoid errors when entering codes, by displaying the allowed choices. The data
entry tabs are:
• Facility
• Facility Contacts
• NAICS
• Release Points
• Emission Units
• Emission Processes
• Controls
• Control Paths
• Control Assignments
• Control Pollutants
• Apportionment
• Reporting Period
• Operating Details
• Emissions
• Emission Formula Variables
The rest of the tabs (in gray) are a Worksheet Map and lists of codes for entry of different data fields.
Please do not attempt to edit these lists as they are part of the data validation for the data entry tabs.
The list of tabs is as follows:
44
-------
• Worksheet Map (containing JSON Keys)
• Aircraft Engine Type Code (for airport SCCs only)
• Calculation Material Code
• Calculation Method Code
• Calculation Parameter Type Code
• Contact Type Code
• Control Measure Code
• Emission Factor Code
• Emission Formula Variable Code
• Emissions Operating Type Code
• Facility Category Code
• Facility Source Type Code
• FIPS County Code
• FIPS State Code
• HAP Facility Category Code
• NAICS Code
• Operating Status Code
• Pollutant
• Program System Code
• Release Point Type Code
• Reporting Period Type Code
• Source Classification Code
• Tribal Code
• Unit of Measure Code
• Unit Type Code
The blue data entry worksheets have the same entities that are presented in the web application, for
example: facility level data, release points, and emissions units. There are several fields that are
required in the spreadsheet so that it can be used in CAERS successfully. These fields are denoted by an
asterisk in the column header (row 10). Be sure to enter values or select an option from the dropdown
menu in each of the required fields.
There are also relationships among some of the blue data entry worksheets. For example, the "Emission
Processes" worksheet will ask for the corresponding Unit ID for each process row. The options in the
"Unit ID" dropdown menu on the "Emission Processes" worksheet are based on the units that are
available on the "Emission Units" worksheet. As new units are added on the "Emission Units"
worksheet, they will be automatically added to the "Unit ID" dropdown menu on the "Emission
Processes" worksheet. Therefore, you need to enter your emission units before they are available in the
"Emission Processes" worksheet. Other instances where fields are dependent on other worksheets
include:
• Control Assignments worksheet:
o Path ID relies on entries from the Control Paths worksheet,
o Control ID relies on entries from the Controls worksheet,
o Control Path (Child) relies on entries from the Control Paths worksheet
45
-------
• Control Pollutants worksheet: Control ID relies on entries from the Controls worksheet
• Apportionment worksheet:
o Release Point ID relies on entries from the Release Points worksheet,
o Process ID relies on entries from the Emission Processes worksheet,
o Control Path ID relies on entries from the Control Paths worksheet
• Reporting Period worksheet: Process ID relies on entries from the Emission Processes worksheet
• Operating Details worksheet: Reporting Period relies on entries from the Reporting Periods
worksheet
• Emissions worksheet: Reporting Period relies on entries from the Reporting Periods worksheet;
• Emission Formula Variables worksheet: Reporting Period Name relies on entries from the
Emissions worksheet
There is special formatting in the bulk upload template, such as hidden fields and formulas. Ensure that
you are keeping with the correct format for each data field and are using the codes as indicated by the
drop-down menus. Many fields that are required by the CAER System are hidden from view in the
spreadsheet to help avoid uploading mismatched data, for example associating an emissions process to
the wrong emissions unit. Use caution when performing certain actions within the bulk upload
spreadsheet. Here are examples of potential risks:
• Overriding formulas: Within Excel, if you copy several horizontally adjacent cells of data and
paste them into the CAERS Bulk Upload spreadsheet then you risk overwriting a necessary
formula in a hidden field. However, you can safely copy and paste data vertically within a
column.
• Overriding drop-down menu values: Pasting data into a field which has a drop-down menu will
allow you to enter any data; however, if the value does not precisely match one of the values in
the drop-down menu then the upload will return an error.
• Deleting drop-down menu: Deleting a cell that has a drop-down menu can potentially delete
the drop-down menu completely. While deleting the entire cell will cause a problem, deleting
the content of the cell is not a problem. For example, if cell E24 has a value of "CAP" then you
can delete "CAP" but should not delete cell E24.
• Overlooking changes to other worksheets: when an error is fixed in a parent cell, connected
cells do not refresh automatically. Be sure to update the connected cells even if the change
doesn't alter the connected cells. For example, when you enter a Unit ID on the "Emission
Units" tab, that value will be available as an option in the Unit ID dropdown menu on the
"Emission Processes" tab. If you navigate back to the "Emission Units" tab and change a Unit ID
then you will need to manually update all of the rows on the "Emission Processes" tab that have
the unit chosen. There may be a cascading effect with this example if the process has already
been chosen from the Process ID dropdown menu on the "Apportionment" tab. In this scenario,
you would need to update the Unit ID on the "Emission Units" tab, reselect the unit from the
Unit ID dropdown on the "Emission Processes" tab, and reselect the Process ID on the
"Apportionment" tab.

3.2 Bulk Upload Steps
Once your data is ready in the bulk upload template, from the "Emissions Reports" screen click on
"Upload Report". Click on the "Browse" button to find the location of your bulk upload workbook on
your computer. Once you have found the workbook, select it and the file name will now appear on your
screen. Click the "Upload" button. A pop-up window will appear to show that the workbook is being
uploaded. The speed at which this happens will depend on your internet connectivity speed. The
upload may take several minutes depending on the size of the file.
It is good practice to give yourself extra time to address any errors that may emerge when using bulk
upload. CAERS will run validations checks on your Excel file before allowing you to submit it, such as
verifying that the required fields are present and that text fields do not exceed maximum lengths. These
validation checks will be different than the QA checks that will be run on the data contents once it has
been uploaded. Validation checks are run for the data file structure and format, whereas QA checks are
run on the data contained in the file.
If the uploaded spreadsheet has errors that keep it from uploading to CAERS successfully then you will
see a list of "Data Errors" on the screen. Each error will indicate the worksheet and row in error, as well
as a brief message describing the error. After all the errors have been resolved, you can attempt to
upload the file again. If there are not any errors in the uploaded spreadsheet then you will be brought
directly to the "Report Summary" for the uploaded report. At this stage you can navigate the CAER
System as described in Section 2.
47
-------
4 Performing Quality Checks
When you have finished entering or uploading your data, the next step is to run the quality checks.
Click on "Report Summary" on the left-hand side menu of your screen to go to the Report Summary
page. Click on the "Run Quality Checks" button below the "Report Summary" table. This will take you
to a "Quality Review" page where you will see two types of errors listed (Figure 47):
• Critical errors will appear in red. These errors must be addressed for the report to go through.
• Warnings will appear in purple. These errors will not prevent you from submitting the report,
but they will alert you to potential issues you may want to address before submitting.
Broadly speaking, error messages fit in one of the following categories:
• Calculation errors - Data calculated outside the form that doesn't match up with what
the CAERS is calculating, for example:
¦ your reported emissions for a process and pollutant are not within 1%
(warning) or 5% (critical) of the emissions CAERS is calculating.
• Inconsistent data entries - Data entered is not possible given some physical or temporal
constraint, for example:
¦ 100% of annual emissions for 52 weeks of operation have been entered
as occurring during the Winter season;
¦ the latitude for a release point has been reported but is too far from the
facility (outside of its facility latitude threshold);
¦ an emission factor was provided, but its denominator is in different
units of measure than throughput, so a simple conversion is not
possible; and
¦ the reported emissions previous year reported emissions are identical
to the previous inventory year reported emissions.
• Expected information is missing - Data are expected to be entered, but the data field is
empty. This includes data fields that are conditional on the entry of others. Examples
include:
¦ in the EPA emission factor, the "I prefer to calculate the total emissions
of this pollutant" has been checked but the "Description of Calculation"
box has not been populated;
¦ controls exist that have not been assigned to a path; and
¦ if a release point stack diameter is reported, then exit gas flow rate and
exit gas velocity should also be reported.
• Incorrect format - Data must be entered in a specific format, for example:
¦ postal code must be in five-digit or nine-digit format; and
¦ value for a year must be four digits.
• Data is not allowed - Data entered is not allowed, for example:
¦ duplicate ID was entered for the same component (unit, release point,
process, or control), but ID's for sub-facility components must be unique
within the facility;
¦ units of measure that are not supported are being used; and
48
-------
¦ SCC entered has been retired in a year prior to the inventory year being
reported.
In the case of data that are not allowed, some legacy data may have been carried into the CAER System.
While the old data will be displayed, the system may require you to update it. For example, in a
previous submission you used a unit of measure code "Million BTUS", but the system now requires you
to enter the new code "E6BTU". Be sure to update the information by selecting a valid code from the
drop-down list.

Click on "Quality Checks" link on the left-hand side of your screen to return to the "Quality Review"
page. When you return to the "Quality Review" screen the error will have disappeared. Once you have
finished correcting your errors you should re-run the quality checks. Once you have addressed all errors
you will see the "Quality Review" screen devoid of error messages (Figure 49). You will also see the blue
line has advanced on the top of your screen to show that the quality checks step has been completed.
While you will be able to use the bulk upload feature, at this time, the application will not be able to
bulk download your submission into the Excel template format. Consequently, if you choose to edit
your errors from the user interface, you will not be able to download those edits to continue your edits
in the bulk upload template. If you submitted your report using bulk upload, you may want to do all
edits in the template and upload it again. Such an approach ensures that your bulk upload template is
correct, to make it easier to use if you have other corrections or data to submit through bulk upload.

5 Certifying and Submitting to your State, Local, or Tribal Authority
As a certifier, you will log into CAERS and chose the "certifier" role from the "My CDX" page (Figure
8). You will see the same screens as the preparer. However, when you are in the "Report Summary"
page, you will see an additional button "Certify and Submit to SLT" (SLT stands for State, Tribal, or Local
authority). When you are ready to certify that your submission is complete and accurate, click on that
button. This will take you to a three-stage (CROMERR) process. First, it will request your password,
then it will ask you to answer a security question. Finally, it will ask you to click certify (Figure 50). You
will see a "please wait" sign while you are waiting. Once the submission has been certified, a message
will appear in green at the top right of your screen. The progress bar at the top of your screen will have
changed and "Submit to SLT Authority" will now be highlighted in blue.
51
-------
Figure 50. Submission Certification
After certifying, your report will be available for you to either reopen or review. We do not recommend
reopening your report unless you have an edit, as it will have to be re-certified and re-submitted. You
should contact your SLT authority if that is the case, to notify them of any changes you intend to make.
You will also want to reopen the report to make corrections, if your submission has been sent back to
you.
Once you have submitted your report, you will be able to click the "Report" button to obtain a summary
report for your records.
6 Submission Approval
Once the report has been submitted, your SLT Authority (GA DNR) will review the report. The
person listed under "Emissions Inventory" contact for your facility will be notified of whether the report
was approved or rejected. If rejected, comments in the email will explain the issue(s) to be addressed.
At that point you should re-open your report and issue the corrections indicated by your SLT Authority.
If your contact person will change at any time after the report was submitted, please let staff at GA DNR
know so the new contact person can be approved to enter CAERS and issue any corrections as needed.
7 Using Data Reported in CAERS for a TRI-MEweb submission
If you are an NEI-TRI facility reporter, you may start a TRI and NEI reportable chemical Reporting
Year (RY) 2019 Form R in TRI-MEweb at anytime before the July 1 TRI reporting deadline. You should
follow these steps to use data reported to CAERS in TRI-MEweb to save time reporting to both systems.
1. Upon arriving to Section 5 of the RY 2019 TRI Form R, an API call will verify if your EPA Facility
Registration ID and CAS number match any data point in the CAERS database. Data in the CAERS
database must be certified for it to be used in TRI-MEweb. See Figure 51.

-------
The new way of setting up controls for emissions reporting will include the following features:
• A list of controls can exist for the facility as those controls exist in the real world.
• A control will only define one single piece of control equipment.
• Only the pollutants impacted by this piece of equipment will be listed with the control.
• The percent reduction for the pollutant will be the amount of emissions reduced due to this one
piece of equipment.
• The "path" of can be described with the data:
o In series
o In parallel
There will be three new items to track in the new controls approach that are worth explaining. A few
examples are included to illustrate the application of the concepts:
1. Control Path: defined as one or more controls at a facility that are linked. The path will allow
the user to define multiple kinds of control setups. A path can consist of controls or other
"children" paths. A path cannot refer to itself (or another path that contains it). Ultimately,
there should be a "master path" that will define the controls that are encountered from the
emissions generation point to the release point. That is, there should ultimately be at least one
master path between a unit and a release point. These concepts will become clearer in the
examples to follow.
2. Control Apportionment: defined as the percentage of the emissions that flows to the next
control or path. For example, if emissions coming out of one control flow into one other control
in a series, then the control apportionment is 100%. If emissions from one control flow to two
or more other controls or paths, then the combined apportionment of those emissions to the
other controls or paths must be equal to 100%. For example, 60% of emissions move from
control 1 to control 2, and 40% of emissions flow from control 1 to control 3.
3. Control Assignment: defines the sequence or order in which controls are configured within a
path. The first control in a path would have sequence number 1, the second control would have
sequence number 2, and so forth. If there is a path within the path, that path will also have a
sequence number.
8.1 Example of a Facility with No Controls
A facility that has no controls does not need to create any paths. All the user must do is provide a
release point apportionment for the process(es) that send emissions to one or more release points.
Figure 55 shows a graphic example of a facility with no controls. The red arrow represents emissions
that ultimately move from the process to the release point: in this case all Process 1 emissions go to
Stack 1. Table 5 shows how the data would be entered into the CAERS (or the bulk upload template) for
the facility absent any controls. In this example, emissions from Process 1 are sent to Stack 1, so Stack 1
is apportioned 100% of Process 1 emissions.

If the process emits to more than one release point, then the relevant percentage of emissions
ultimately moving from Process 1 to each release point would need apportionment percentages. For
example, assume that Process 1 emissions ultimately go to all three stacks with 50% going to Stack 1,
25% of its emissions going to Stack 2 and 25% going to Stack 3. In this case, the release point
apportionments would be as shown in Table 6.

the release point. In this scenario, assume there is one process, Process 1. The Control 1 is placed in
Path 1. The control apportionment is 100% and the control assignment sequence number is 1. Table 7
shows the assignment of the control. Table 8 shows the associations for that control and the other
relevant sub-facility components.

8.3 Example of a Facility with Controls in Series
In Figure 57 we can see an example of a facility that has controls in series. Assume there is one
process per unit, Process 1 and Process 2 for Boiler 1 and Boiler 2 respectively. In this case, there are
three controls. Controls 2 and 3 have been placed in Path 1. Path 2 contains Control Device 1 and Path
1. Path 1 is a child path of Path 2.
58
-------
You should configure your controls into paths is a matter of how your controls are laid out in the facility
from the units to the release points. There should ultimately be one master path between a unit and a
release point. In this case, that master path is Path 2. If more than one process is being run from the
unit, then all the processes would be associated with the control path in the same manner as Process 1.
Figure 57. Example of a Facility with Controls in Series
For this example, we can see in Figure 57 that the controls are in series. The emissions flow directly
from one control to the other. Thus, the control apportionment for Control 1 to Path 1 is 100%, and the
control apportionment for each control within Path 1 is 100%. In Path 1, Control 2 is first in the
sequence, Control 3 is second. In Path 2, Control 1 is first in the sequence, Path 1 is second in the
sequence, and, and Scrubber 1 is third. Table 9 shows the assignment for this facility. Table 10 shows
the associations for the different sub-facility components. Also, note that all emissions enter Stack 1
after leaving Path 2 (as indicated by the red arrow). Note that 100% of emissions from Process 1 went
to Stack 1, and 100% of emissions from Process 2 also went to Stack 1.

In Figure 59 represents a more complex controls set up. Again, we show just one process for the
unit, but all processes associated with that unit (if shown) would be treated in the same way as Process
1. This controls setup is a combination of controls in series and parallel. Path 1 contains Control 2 and
60
-------
Control 4. Path 2 contains Control 1, Control 3, and Path 1 (child path), and Control 5. Path 3 contains
Path 2 (child path), and Scrubber 1.
Figure 59. Example of Complex Controls
Figure 60 shows the different assignments and apportionments given this set up. In Path 1, Control 2 is
first in the sequence, Control 4 is second, and 100% of emissions flow from Control 2 to Control 4, and
100% of the emissions flow to Control 5 from Path 1. Path 1 is a child path of Path 2. In Path 2, Control
1 sends 60% of its emissions to Path 1 (where Control 2 is first in the sequence), and 40% of its emissions
go on to Control 3. Then 100% of emissions go from Control 3 to Control 5, 100% of emissions exit Path
2 (via Control 5) to Path 3. In Path 3, Path 2 (child path) is first in the sequence, then the Scrubber is
second in the sequence. Assignments are shown in Table 11. How the different sub-facility components
are associated is shown in Table 12. Note that 50% of emissions from Process 1 go to Stack 1, and 50%
of emissions from Process 1 went to Stack 3 (as indicated by the red arrows in Figure 59).

9.3 Additional Resources
9.3.1 General Energy Conversions
The CAER System will allow you to do simple conversions within the same type of measure, for
example conversions between different units of measure for weight. For energy related conversions,
visit: https://www.eia.gov/energvexplained/units-and-calculators/energy-conversion-calculators.php.
The website contains information about conversions and a conversion calculator. Note that ultimately,
conversions between quantities of fuel and heat will depend on the specific conditions in which the
processes involved are being conducted. You should consult GA DNR for guidance as to whether a
certain type of conversion is appropriate for a specific process. You can include assumptions about
conversions in the Comment fields provided in CAERS.

9.3.3 Volume Conversions for Natural Gas
Volumetric conversions of natural gas depend on the physical conditions of the natural gas as
follows.
To convert the volume of natural gas below 60 psia:
Under these conditions the Ideal Gas Law can be applied. Subscript 1 indicates gas at one set of
conditions of absolute temperature (T) in degrees Rankine (°R), and absolute pressure (P) in pounds per
square inch absolute (psia), subscript 2 indicates the same gas at a different set of conditions for the gas.
VI = Tl/Pl (P2 V2/T2), to get VI in cubic feet (cf).
A standard cubic foot (scf) of gas is defined as a cubic foot at a temperature of 21 °C (70 °F or 530 °R)
and a pressure of 101.325 kilopascals [kPa] (14.696 psia), except for liquefied petroleum gas.
So if converting from a gas with volume V2 at standard cubic feet of gas to VI, the formula to apply
would be:
V1=T1/P1 (14.696 x V2)/530
To convert the volume of natural gas above 60 psia:
Natural gas does not behave like an ideal gas in this case. The formula requires a compressibility factor
(Z).
V1=V2(Z1 T1 P2)/(Z2 T2 PI), to get VI in cf,
where Z1/Z2 is the compressibility ratio.
For example: If converting from a gas with volume V2 at 60 °F (or 520 °R) and 14.73 psia to another
volume, the formula would be:
V1=V2(Z1 x T1 x 14.73)/(Z2 x 520 x PI),

9.3.4 State Emission Factor Compendium
If your SLT Authority allows it, you may use emission factors available from other states. To
browse the Emission Factor Compendium, go to the CAER website and look under the "Development of
a State-Local-Tribal Emission Factors Compendium". You will find three spreadsheets (from Minnesota,
Michigan and South Carolina), that may contain an emission factor your SLT deems appropriate for you
to use.
9.3.5 Example of Controls Calculations
The following example may help you understand how the different percentages involved in controls
calculations are related. This example may help you estimate your "Overall Control %" for your
individual control and/or control path. The example is illustrative, you should work with your SLT
authority to determine the best way to do these calculations for your specific controls configuration.
The following definitions are used in this example:
Percent Capture Efficiency: The percentage of an exhaust gas stream that is actually collected for
routing to a set of control devices. This value could be obtained from the vendor, or measured at the
facility.
Percent Control Effectiveness: The percentage of time or activity throughput that a control approach is
operating as designed, including the capture and reduction devices. This percentage accounts for the
fact that controls typically are not 100 percent effective because of equipment downtime, upsets and
decreases in control efficiencies. This could be estimated from the amount of time the control is
operational, versus down for maintenance or repairs.
Percent Reduction Efficiency: The percent reduction achieved for the pollutant when all control
measures are operating as designed. This could be obtained from the vendor.
Assume you have a control or control path for Particulate Matter with the following:
• capture efficiency (cap) is 90%,
• control effectiveness (effect) is 80%,
• control efficiency (effic) is 95%, and
• uncontrolled (unc) or pre-control emissions total 100 tons.
Then:
"Post control" emissions = unc x cap x effect x (1-effic) = 100 x 0.9 x 0.8 x (1-0.95) = 3.6 tons.
Controlled emissions = unc x cap x effect x (effic) = 100 x 0.9 x 0.8 x 0.95 = 68.4
Non-captured emissions = unc x (1-cap) = 100 x (1-0.9) = 10 tons. Non-captured emissions when the
device is effective would be 8 tons: unc x (1-cap) x effect. The rest (2 tons) would also be downtime
emissions.
"Downtime emissions": The emissions released when the 95% control device and/or its capture device
are not operating properly = unc x (1-effect) = 100 x (1-0.8) = 20 tons.
