CHAPTER 1: INTRODUCTION
1.1 About CALCS
The COMPASS Emission Calculation and Process History (“COMPASS-CALCS” or
“CALCS”) module facilitates the collection, calculation, and reporting of air emissions data for
Emissions Inventory and other reporting.
CALCS uses a relational database as opposed to a spreadsheet for calculations. A database
allows entry and editing of data like in one place, which prevents searching for every instance of
that data in many spreadsheets. This also improves consistency in reporting. CALCS is also
arranged in screens to provide a visually intuitive system that can be passed from user to user.
CALCS relates Sources, Streams and Formulas to compute emissions. Once the data is
calculated, it can be transferred to the EI (Emission Inventory) section of COMPASS for
reporting. CALCS also keeps a history of past years’ calculations.
Other modules of PDC’s COMpliance ASsurance System (COMPASS) are:
• Utilities module imports state EI download (Extract) files.
• PIPELINE module transfers CALCS emissions to the EI module.
• Emissions Inventory (EI) module views and creates a state upload (Delta) file for
submission.
• TaskTrakker assigns and tracks Title V permit tasks.
1.2 System Requirements
The following platform is strongly recommended to operate the CALCS application:
Pentium II PC running at 250 MHz. with 64 megabytes of RAM and 50 megabytes of free
disk space.
The following platform is the minimum required to operate the EI application:
Pentium I PC running at 90 MHz. with 25 megabytes of free disk space and 32 megabytes
of RAM to obtain reasonable performance.
The following operating systems are supported:
Microsoft Windows 95, Windows 98, Windows ME, Windows XP or Windows NT
Operating Environment, (all Trademarks acknowledged).
The following Database Management System (DBMS) software is supported for the
Data Repository:
ORACLE 7.3 and higher
Sybase SQL Anywhere 5.5 and higher.
CALCS–Manual
1.3 Installation Instructions
Directions for the installation are furnished in a separate document entitled “Installation
Instructions,” which is provided with this operations manual. CALCS should always be loaded
onto a local or network hard disk under the directory structure: <drive>:\... \PDC\ACM\CALCS.
The installation program creates this structure below the target installation folder chosen by the
user.
The application and database file can both be on the desktop, both on the network drive, or split
with the application on the desktop for speed and the data on the network for security. The
application file is dadams.exe, and the database file is acm.db. Multiple COMPASS modules
can use the same database file.
The installation routine creates a COMPASS folder under All Programs on the Start menu with
the CALCS icon in place. Double click on the CALCS icon to enter CALCS. A login screen will
appear asking for your User ID and Password.
1.4 Using Help
Help is provided on-line with CALCS and is as extensive as the printed documentation. The online Help allows you to search by topic or keyword for the area in which you need help, and
categorizes and defines words and phrases, giving you a clear picture as to what you are doing.
When you click on Help and Contents, a dialog box will appear with selections for using the help
features of the system. Users can search for a specific topic of interest by using the Index or by
reviewing subject areas. Users may also review the version number of CALCS by clicking on the
submenu item About.
1.5 Technical Support of CALCS
Technical Support of the system is provided by PDC Corp. Please be aware that support
technicians will be handling many users, so you can help them by doing the following:
Please carefully read this manual to be sure that your question or problem has not been
addressed.
Make sure that the Data Sources section in your control panel is configured properly to run
the CALCS database, which is called ACM.db. If you are not using Oracle, then the drivers
for ODBC will also need to be loaded for proper program operations.
If you are running on a Network, check with your system administrator to make sure your
workstation is configured correctly to run the program and connect to the database, and
check that you have the rights to modify a file in the drive and directory where CALCS is
loaded (namely, the database file ACM.db).
If your issue is not addressed in this manual and you are satisfied that your system
configuration is correct, feel free to call PDC Corp. Please have information about your
system, including Windows version and type of network.
ACM-CALCS–Manual
Page 2
1.6 Getting Started with CALCS
The installation routine will automatically create ODBC connection Profiles, path adjustments,
and a COMPASS folder on the Start menu with an icon for the CALCS login screen. Click on
the CALCS icon to access the CALCS main screen.
1.7 About This Manual
This manual assumes that the user knows some basic chemistry, environmental, spreadsheet and
Microsoft Windows concepts. Uncommon terms and CALCS terms will be explained. CALCS
terms in a sentence are often capitalized and refer to labels on the described screen.
1.8 Pre-entered data
CALCS contains a standard library of chemical Compounds with their Properties, as well as
many AP-42 formulas, already in place. You may first be supplied with a demonstration
database with example Sources to use for practice. Often your company will later have PDC
enter all your site’s Sources, Stream Properties and other data previously in spreadsheets. This
allows the user to start with a ready-to-use application.
1.9 Data fields
CALCS has a number of different screens with fields for data. Some fields are mandatory before
data can be saved. Other fields may need data, because they are variables in a calculation
Formula. Some fields must be completed to take advantage of certain CALCS features. For
instance, all Compounds in a Stream must have molecular weight entered, before you can use the
“Calc” button next to the “MW Liquid Phase” field to automatically calculate that value. The
rest of the fields can remain blank or be used as a storage place for miscellaneous data, thus
changing that data will not necessarily affect calculation results.
ACM-CALCS–Manual
Page 3
1.10 Logging onto CALCS
When you click on Start, All Programs, COMPASS and Calculations Module, a login window
will appear. If you are using an Oracle database, enter your User ID and Password, select Oracle
as the database, and then click OK. If you are a SQL Anywhere user, you may leave the default
entries as-is and then click OK. A password is not required for SQL Anywhere.
CALCS can handle more than one Facility (site). If a Select Facility
screen pops up, pick your Texas account number to start. Then the
CALCS Main Screen will appear.
1.11 Important Conventions for Entering Data
Identifying numbers (ID’s) should be in all upper case letters and have no spaces. Otherwise,
confusion may arise over the difference between TANK1, Tank1 and TANK1[space]. For
simplicity, leave the cap lock on for all entries.
You will find that the Enter key is not active for all fields. In that case, use the Tab key or click
on the next desired field.
Click the Save button to save entries into the database. If your screen does not have the
minimum mandatory data when attempting to save, a pop-up window will advise you what is
missing. Enter the missing data and click Save again.
Items entered on one screen often become pick list items on a second screen. For instance, if the
Source screen does not have a desired Unit on the pick list, it must be added on the Units screen.
If the Source screen was left open during work on the Unit screen, the Source screen will need to
be refreshed to display the new Unit. While in the Source screen, click Save, select another
ACM-CALCS–Manual
Page 4
Source ID and go back to the original Source ID or close and reopen the Source screen.
Fields in yellow are the ones that normally must be updated each time period, but there may be
others in your case. See the Profile and Formulas linked to the Source to find the variables that
must be changed. It may be advisable to list those fields in the Source Comments.
1.12 Exiting CALCS
To exit, simply select the Exit icon on the main screen, or choose the Exit selection from the File
menu. You will be presented with a confirmation window, so select Yes.
ACM-CALCS–Manual

CHAPTER 2: CALCS OVERVIEW
2.1 CALCS Main Screen
Upon logging in, the main screen appears, with a row of buttons to open other screens for
entering or viewing data.
Above the buttons are menu items for File, Process, etc. Clicking on these will often give an
option to the buttons. For instance, clicking Reference, then Facility Information opens the same
screen as clicking the Facility button. The menus also open advanced functions.
ACM-CALCS–Manual
Page 6
2.2 Facilities
Note that a CALCS Facility is a site, often designated by an Account Number. This should not
be confused with a CALCS Source, which is often associated with Facility Identification
Number or FIN. You may, upon entering CALCS, need to select a default Facility (site) to work
with.
The Facility section of CALCS is the same as Facilities set up in COMPASS - TaskTrakker.
You may, of course, choose any Facility already set up in TaskTrakker to work with, but you
may not modify certain Facility data, such as the account number, once the Facility is in the
Database.
ACM-CALCS–Manual
Page 7
ACM-CALCS–Manual
Page 8
2.3 Units
Units are process unit types, such as sulfur recovery units, tank farms, and powerhouses. The
same Unit may be used in multiple Facilities because it is a unit rather than a physical area in a
specific plant. Units are associated with process Streams and emission Sources in CALCS.
ACM-CALCS–Manual
Page 9
2.4 Compounds
Compounds can be ingredients (xylene, etc.) in a Stream or air contaminants (NOx).
Compounds are linked to Stream Properties and Formulas. The Compounds screen contains
physical and chemical data, such as molecular weight, density, vapor pressure coefficients and
reporting categories like SARA (Toxic Release Inventory) and HAP.
ACM-CALCS–Manual
Page 10
2.5 Stream Properties
A Stream can be the contents of a tank, the fuel for a boiler, the material leaked from piping
components or even the exhaust from a stack. It may be a gas, liquid or solid. The Stream
Properties screen shows the Compounds (ingredients) and their relative amounts in the Stream.
It also can contain data such as molecular weight of the mixture’s liquid or vapor states, sulfur
content and heating value (for fuels). Only the data that will be used in a calculation Formula is
required to be filled in. For example, BTU value of a Stream is important for fuel Streams, but it
may be left blank in a tank or loading Stream.
ACM-CALCS–Manual
Page 11
2.6 Unit/Streams
CALCS links a set of Stream Properties (Stream Composition) with a Unit to create a
Unit/Stream, which is the actual Stream.
ACM-CALCS–Manual
Page 12
2.7 Sources
Sources are the generators of the emissions you will be calculating. They are often identified in
Texas by the Facility Identification Number (FIN). Sources include boilers, engines, flares,
manufacturing process Units, and other equipment. See a tank example below.
ACM-CALCS–Manual
Page 13
2.8 Formulas
The Formula is the equation that calculates Source emissions. It uses raw data previously
entered in the Source and Stream Properties screens. A Formula calculates average pounds per
hour of a single air contaminant like NOx or perhaps a category total like VOC. See a carbon
monoxide (CO) Formula below. Note the standard AP-42 emission factor (ef) of 84 lbs CO per
million cubic feet of natural gas is multiplied by (*) the fuel usage converted to million cubic
feet, then divided by (/) operating hours to obtain pounds CO per hour.
ACM-CALCS–Manual
Page 14
2.9 Profiles
An emission Profile is a list of Formulas. Each Source is linked to one such Profile A boiler
Profile would have 5 Formulas to calculate NOx, CO, SO2, PM and VOC. Note the Formula
FURNCO from the figure in the previous section is on the “Methodcode” list below.
ACM-CALCS–Manual
Page 15
2.10 Calculate
The Calculate button runs calculations for a selected Source(s) and date range. The results are
stored as a history, so that you can later determine the basis of reported emissions for any year.
ACM-CALCS–Manual
Page 16
2.11 Inventory
The Inventory button allows a spreadsheet view and editing of all emissions after calculating is
complete.
2.12 Exit
The Exit button closes CALCS.
ACM-CALCS–Manual
Page 17
2.13 Linking Related Items
Data saved in certain screens appears in a pick-list on later screens. Thus, one screen feeds
another. If you pick a Compound from the pick-list in the Stream Properties screen, you link the
two. Stream Properties are linked to Units as Unit/Streams. A Unit/Streams is linked to a
Source. A Source is linked to a Profile, which is linked to one or more Formulas. A Source is
also linked to a Facility and Unit. With all the links complete, you can calculate emissions. See
the examples in the diagram below.

4.1.1 File Menu
Above the Main Screen buttons are menu items. Depending which screen is open, the menus
change to offer options related to that screen. Some menu items are available only when all
button-activated screens are closed. Other items are only available when the related screen is
open.
ACM-CALCS–Manual
Page 22
The File menu of CALCS only allows one selection if no screens are open, which is to Exit the
CALCS program. Use this selection when you are finished working in CALCS.
After opening a screen, other File options appear, depending on the screen. These options are
familiar to Windows users.
ACM-CALCS–Manual
Page 23
4.1.2 Process Menu
The Process menu in CALCS gives you access to Emission Sources, Stream Properties and
Compositions, Emission Source Profiles and Copy Data to Another Year. The Stream Properties
and Emission Source Profiles items open the same screens as the Stream Properties and Profiles
buttons. A sub-menu of Emission Sources allows selection of Sources, Quick Edit and Import.
These open the same screens as clicking the Sources, Quick Edit and Import buttons. Quick Edit
and Import will be discussed later.
The last item, Copy Data to Another Year, copies all process history records from a user-selected
base year to a target year. If, for example, there are twelve process history records in the base
year, one for each month, for a storage tank, then twelve new records will be created in the target
year for that tank.
If desired, a Scaling Factor may be entered in the Units window before using this feature. If the
user enters a scaling factor of “0.5” for, say, Unit #2 and checks the Unit Scaling box above, then
all process history records will be duplicated, but the process rate for all Sources in Unit #2 will
ACM-CALCS–Manual
Page 24
be changed to a value that is one-half as large as the values in the base year. Manually entered
emissions may also be copied to a new year if this feature is selected by check box shown near
the bottom of the screen.
ACM-CALCS–Manual

4.1.3 Reference Menu
The Reference menu allows you more options to the button row:
•
•
•
•
•
•
Facility Information = Facility button
Compounds = Compounds button
Units = Units button
Streams = Unit/Streams button
Stream Source Relationships = Relations button
Emission Factors = Formulas button
The Reference menu is also where the Equipment Leak functions are found. These will be
discussed later under the Equipment Leaks chapter.
4.1.4 Emissions Menu
The Emissions menu shows the Estimate Emissions (same as Calculate button) and View
Emission Results items (same as Inventory button).
ACM-CALCS–Manual
Page 26
4.1.5 Options Menu
The Options-Setup menu allows you to select a default Facility to work within. Once the Facility
is selected, you may only do data modification on equipment or Sources within that Facility until
you select another default Facility.
4.1.6 Maintenance Menu
The Maintenance menu has five options and is viewable only when all screens are closed. Stack
Tests has fields for entry of stack test results to be used later as a basis for emission rates.
Compound Lists are lists made by the user for emission calculation of only certain Compounds.
Source Type Display allows rearrangement of the order of Source Types in pick lists. Disable
Formula Edit allows locking and unlocking of General Formulas such as those from AP-42.
Cleanup Database is generally used after calculating emissions to remove streams not used in the
database, Stream Compositions not linked to a Unit/Stream, records showing zero emissions, and
emissions not linked to current Facilities or Sources.
ACM-CALCS–Manual
Page 27
4.1.6.1 Stack Test
This screen allows entry of stack test results. These results can later be used in a Formula.
ACM-CALCS–Manual
Page 28
4.1.6.2 Compound Lists
This screen allows the user to choose a number of Compounds and name the list. Just enter the
name of the list, double click Compounds to be added to the list and Save. Use the three radio
buttons to limit the size of the pick list to the left.
ACM-CALCS–Manual
Page 29
4.1.6.3 Source Type Display
This allows one to change the order of Source Types in pick lists by changing the order number.
If all numbers are the same, the list will be alphabetical. Otherwise, the list will be from lowest
to highest number. You can also Hide unused Source Types by dragging them from the right to
the left column.
4.1.6.4 Disable Formula Edit
Some emission Formulas should not be edited, such as from AP-42. The Disable Formula Edit
function prevents users from changing Formulas labeled as General in the Formulas screen. It
saves the time of reconstructing long Formulas that were inadvertently changed. After clicking
this item, you will only need to click Yes or No for confirmation.
ACM-CALCS–Manual
Page 30
4.1.6.5 Cleanup Database
With time, a database will accumulate many obsolete records. The Cleanup Database option
opens a screen to choose among four types of unnecessary data to remove from the database as
shown in the figure below. Removing such data will remove unused items from pick-lists, speed
up the Calculate function and save hard drive space. Streams Not Used In The Database are
those that are not linked to any Source. Stream Comp (or Stream Properties) Not Linked To Any
Stream is self-explanatory.
Zero (0) Tons/Yr of Speciated Emissions occurs when one Profile is used for many Sources. A
Profile may call for calculation of xylene, because it is in one Source. If a different Source using
that Profile has no xylene, its speciated emissions will also list xylene, but with zero tons.
Profiles with long lists of Compounds can cause accumulation of thousands of zero emission
records in the database. This function removes them.
Emissions Not Linked To Current Accounts/Sources are “orphaned” emissions that can be
deleted.
After choosing one of the four options, click Retrieve to see the list of unnecessary data. You
can highlight data individually or click Select All, then Delete and Save. Clicking Invalid Accts
will delete data pertaining to obsolete accounts. Some of these functions take a lot of time if
there are large numbers of records, so plan accordingly.
ACM-CALCS–Manual
Page 31
4.1.7 Window Menu
The Window menu allows you to arrange multiple screens into the familiar Tile, Cascade or
Layer configuration. If you click Toolbar, a pop-up gives options of moving the button row to
the left (as in the figure below), right, top or bottom. Also, you can create a floating square
window of buttons or hide the buttons altogether and use the menu bar. You can uncheck the
Show Text box to shrink buttons once you are familiar with the icons. These options allow the
best use of screen space.
Also, when multiple screens are open, they will be listed below the Toolbar item, so you can
switch between screens.
4.1.8 Help Menu
The Help menu in CALCS gives you access to the on-line Help system Contents and version
information relating to CALCS and COMPASS.
4.2
Facilities Screen
You may view and modify Facilities that exist in CALCS. If Facilities are resident in
COMPASS, they will also be present in CALCS. To enter the Facility section of CALCS, select
the Facility icon. This will bring up a screen where you may add, modify, or delete company and
ACM-CALCS–Manual
Page 32
contact information. The screen is shown in the CALCS Overview chapter.
To select an existing Facility, click on the drop down list on the Facility Code field. Clicking on
the desired Facility will fill out the data entry boxes with the currently installed data items for
that particular Facility. Notice the vertical scroll bars on the right side of your screen that will
allow you to view the rest of the data. Once you have made any modifications to the data, select
the Save icon. The ID is the link to other entities and should be all upper case with no spaces to
avoid confusion.
4.3 Units Screen
Click on the Units icon for this screen. All Sources and Unit/Streams must be linked to a Unit.
While this takes more effort, it allows for unit specific emission calculations, generally for
internal use. To enter a new Process Unit, click on the Insert icon. This will open up a data box
directly under the last existing Unit and place the cursor in that box. You may enter the data as
needed, selecting the Save icon when finished. You may delete an existing Process Unit by
selecting that record and clicking on the Delete icon. You will be asked to verify the deletion, so
choose Yes. To print the listing of Process Units, click on the Print icon.
The Process Unit Number is the identifier used to link a Unit to a Stream Property or Source. It
can consist of up to 20 characters. After entry, the Units will appear in a pick-list in other
screens. The ID is the link to other entities and should be all upper case with no spaces to avoid
confusion.
ACM-CALCS–Manual
Page 33
The Units screen includes a column called “Scaling Factor”. This factor may be used in
conjunction with another feature to copy all of the process history data for all Sources from one
year to another year. This would normally be done annually to save the time of creating new
date ranges for every Source separately. That feature is accessed by clicking on the Process
menu, and then clicking on the menu item called “Copy Data To Another Year”.
If the Scaling Factor for, say, Unit #1 is “1” or is not filled in, and the “Copy Data To Another
Year” feature is selected, then all process history records will be duplicated for the selected
target year. If there are twelve process history records in the base year, one for each month, for a
storage tank, for example, then twelve records will be created in the target year, with exactly the
same throughput.
If the Scaling Factor for, say, Unit #2 is “0.5”, and the “Copy Data To Another Year” feature is
selected, then all process history records will be duplicated for the selected target year, but the
throughput for all tanks and loading racks that are located in Unit #2 will be changed to a value
that is one-half as large as the values in the base year. In fact, all Sources located in Unit #2 will
have their process or activity rate (e.g., fuel usage for combustion, flare gas burned for flares,
etc.), changed per the scaling factor.
Note that this feature does not scale emissions directly, only process rates. Therefore, the effect
on emission estimation is as defined in the estimation Formulas. If process rate is an important
calculation variable (e.g., storage tanks), then the scaling of process rates will have a significant
effect. If the process rate is a minor variable, or if it is missing altogether from the Formula (e.g.,
fugitive emissions), then the scaling of process rates will have little or no effect on emission
rates. The Scaling Factor is only useful if all or most process rates in an entire Unit change by
the same ratio.
The Area column may be completed by the user for information purposes only.
To see all Sources in a Unit, highlight the Unit, click the Options menu, and then Unit
Equipment Information. This option is available only when the Unit screen is open.
Click on the Close icon when finished editing the process Units data to return to the main
CALCS screen.
ACM-CALCS–Manual
Page 34
4.4 Compounds Screen
Compounds are not related to any operating Facility; the same Compound list can be used for all
plants. Click the Compounds button to open this screen. Compounds default to alphabetical but
can be sorted by any parameter by clicking on the heading for the column. A Compound can
also be found by searching for the CAS number or Compound Name by clicking the drop-down
list and typing the first few characters.
To add a Compound, click Insert and enter at least the name, CAS number and whether it is a
Single or Multiple Compound, and Save. The CAS number can be up to 11 characters and is
usually typed with hyphens in the form 00000-00-0. When no CAS number exists, it can also be
a name like “VOC”. If there is a Texas contaminant code but no CAS number, the CALCS CAS
number can use the first 5 digits of the Texas contaminant code, followed by zeroes. For
instance, the PART-U contaminant code is 10000, and its CALCS CAS number is 10000-00-0.
The CAS number is the ID that links to other entities and should be all upper case (if it contains
letters) with no spaces to avoid confusion. Do not change or delete a CAS number after using
that Compound in Stream Properties or further into CALCS. This will cause all emissions for
ACM-CALCS–Manual
Page 35
that Compound to be lost. If you must change the CAS number, follow the steps in the
Troubleshooting chapter in the section PIPELINE Steps with Troubleshooting.
A Single species example would be xylene, whereas a Multiple species would be VOC. Multiple
species can be further speciated and will appear at the top of emission reports when using
Calculate. Although unspecified contaminants like VOC-U could be considered Multiple, they
would normally be entered as Single, because they are generally used when further speciation is
unknown, and they are usually part of the Multiple Compound, VOC. That way, total VOC will
be listed at the top of a report, and all species which are subtotals would be listed below,
including VOC-U, xylene, etc.
You can also edit or delete existing Compounds. Be careful when you are deleting Compound
records, as there is no confirmation window in this section.
All fields to the right of the first three columns are optional and need be completed only if they
are referenced by a Formula or needed for an automated CALCS computation like vapor
molecular weight, which requires the vapor pressure and molecular weight of all Compounds in
a Stream. You can also type in data just for future reference.
By scrolling to the right you can view and edit vapor pressure data, which can be entered in three
ways. CALCS will use the data in this preferential order:
•
•
•
Three Antoine coefficients with their lower and upper temperature limits.
Two-parameter coefficients with their lower and upper limits.
Five-points of known vapor pressure at different temperatures.
ACM-CALCS–Manual
Page 36
Scrolling farther to the right, we see the five-point entry fields.
Scrolling more, we see options for putting the Compound in a VOC, SARA, HAP or other
category using a drop-down list.
ACM-CALCS–Manual
Page 37
4.5 Stream Properties Screen
Each Source must have a related Stream in CALCS. Stream Properties are not related to any
specific operating Facility nor to any Unit. The ID will be the key to link a Stream Property to
other entities and can be up to 12 characters long. It should be all upper case with no spaces to
avoid confusion. To add a new Stream Property, just start typing the ID in the blank provided.
To edit an existing Stream Property, use the pick list to find its ID, edit and Save. The ID and
Description at the top are mandatory. Other fields are optional.
Click Insert to add new Compounds to the Stream Property and select them using the drop-down
arrow. Enter the concentration and select units. CALCS will convert the concentration to
weight percent, provided the Compound data is sufficient. The prefix “Cvt” means “converted”.
Formulas usually use the converted quantities. The total concentration is displayed below the list
for reference. CALCS will allow the total to be other than 100% if that is desired. Composition
data may be entered for the liquid or vapor phase of the Stream. For Streams that will not be
speciated, such as a fuel for a boiler, Composition data is not mandatory.
Click the “CALC” buttons to Calculate liquid or vapor molecular weight, or enter them manually
if known. Compound data must be sufficient for this also, as well as the MW Reference
Temperature. Other fields are entered manually if needed. Most of the fields can be used later in
a Formula.
ACM-CALCS–Manual
Page 38
4.6 Unit/Stream Screen
Stream Properties must be linked to a Unit to form a Unit/Stream combination, which is the
actual Stream. A Stream can be searched by name by typing in the first few characters. Rows
can be sorted by clicking on any column heading. Click Insert to add a new Unit/Stream. In the
fourth column, use the Stream Composition drop-down to find the desired Stream Properties.
Likewise, pick a Unit in the third column, and assign the combination a Stream ID and Stream
Name. You can also edit an existing Unit/Stream. Click Save when finished with adding or
editing.
Both the Stream ID and Stream Name should reflect the Stream Properties and the Unit. For
instance, the Stream Composition (Properties) for GASOLINE could be linked to the CRUDE
Unit, given the identifier CRUDEGASO and the name CRUDE UNIT GASOLINE. That way
the name is intuitive when encountered later.
The Stream ID can be up to 12 characters long. This ID is the link to other entities and should be
all upper case with no spaces to avoid confusion.
ACM-CALCS–Manual
Page 39
If you scroll to the right, you can enter more Stream data. The Cleanup Streams button will
delete all Streams not linked to a valid Source. A warning will pop-up that requires
confirmation.
There are two reasons for separating the Streams from Stream Compositions in the system.
1. First, when process history is entered for a Source, users are asked to identify the
Stream(s) that are used by the Source during the process history time period. Sources
are related to specific Units, just as the Streams are; thus, the system can provide a
drop down list of Streams for this selection that is limited to the Streams associated
with the Unit. If there were no relationship of Streams to Units in the System, then the
drop down list could contain several hundred Streams, or more, for a large plant.
Therefore, the Unit/Stream feature makes future use of the system more convenient
and greatly reduces the potential for error (e.g., selecting the wrong Stream for a
Source). It also allows for calculation of emissions by Unit.
2. Second, by separating Stream Compositions from Streams, the user has more
flexibility in using Streams in emission calculations. For example, several Streams
can (and often do) reference the same Composition; thus, if the Composition changes
in some, but not all, Units, the user can add one or more new Compositions and relate
them to the Streams that have modified Compositions only. Also, if several Streams
reference the same composition and the composition changes for all Streams, the user
needs only make the change in one place, at one time, thereby reducing maintenance
of the system.
The extra time that is spent in “set-up” for Streams and Compositions is more than offset by the
ACM-CALCS–Manual
Page 40
increased convenience and more powerful maintenance capabilities that result from this aspect of
the system. Streams, as well as Stream Properties (and many other system entities) are not
related to any specific operating Facility. Even though Streams are related to Units, the Units
themselves can be generic, if the user wishes to set up the database in this manner. For example,
if a company has several gas processing plants that have Amine Units, the Unit called “Amine
Unit” can be entered only once, and an associated Stream, such as “Amine Gas,” can also be
entered only once. This Stream can be associated with Sources located in several different
operating Facilities.
You may also modify existing Stream data by clicking on the field of the Stream record you wish
to modify. Simply overwrite existing data and click Save.
ACM-CALCS–Manual
Page 41
4.7 Relations Screen
If you click the drop-down arrow to the right of the Unit/Streams button, you will see the
Relations button. This button opens the screen that shows relationships between all Streams and
Sources. You can also view and print the complete list.
ACM-CALCS–Manual
Page 42
4.8 Sources Screen
The Source ID or Equipment ID is usually the FIN. The Source ID must be the FIN for the
PIPELINE module to transfer the emissions to the EI module. Secondary Sources can be
different from the FIN, but that will be explained in another section. The ID can be up to 10
characters long. It should be all upper case with no spaces. When first opening the Sources
screen, pick the Facility, the Source Type, then an existing Equipment ID using the drop-down
arrows. If your Source is not under the expected Source Type, search under the User Defined
Source Type.
To add a Source, pick the Source Type, enter a new ID in the Equipment ID field and a General
and Specific Description. The Source Type does not need to be the same as in the EI module.
As soon as you click Save, you create the new Source in the CALCS database. To delete a
Source and all of its data, click the Delete button to the right of the Equipment ID.
If you are adding several nearly identical sources, you can add one manually then click Save As.
A small window will pop-up asking for the new Source ID. Type in the ID for the next Source
and click OK. This will save all data from the first Source as a new Source, including all date
ranges, while leaving the existing Source intact.
ACM-CALCS–Manual
Page 43
4.8.1 Estimation Dates
Data on all tabs is saved by Source and date range. If you change the beginning and ending
dates, and click the Save button, you copy all data on all tabs and save it as a new date range.
Reports under the Calculate function show emissions in tons per “est”, which is the estimation
period chosen for the report. This period could be a year, month, day or any number of days
bounded by the beginning and ending dates for the report.
There are three fields labeled Estimation Dates. The upper right field is read-only and is a pick
list of previously entered date ranges. If you pick an existing date range, the data on every tab
will correspond to those dates. To delete data for just one date range, select the Estimation Dates
from the upper right pick list and click the Delete button to the right.
The other two fields are on either the General or Detail tab and are the editable begin and end
dates. If you wish to enter data for a new date range, enter the new begin and end dates, edit any
data fields like throughput and click the Save button. All data on all tabs will then be associated
with the date range, while leaving the existing one intact. If you look at the Estimation Dates
pick list in the upper right corner, you will see the new date range. It can be viewed at any time
in the future and can be used to calculate emissions.
Date ranges can be a year (1/1/2007-12/31/2007), month (1/1/2007-1/31/2007) or as little as a
day (1/1/2007-1/1/2007). It is important to recognize several concepts. You can calculate
annual emissions from 12 monthly date ranges, but you cannot calculate monthly (or rolling 12month) emissions from a single annual date range. Also, if you want to calculate monthly or 12month rolling emissions, your date ranges cannot bridge two months (1/15/2007-2/15/2007).
You must express month-bridging dates in parts (1/15/2007-1/31/2007 then 2/1/2007-2/15/2007).
Also, your date ranges should not have gaps (1/1/2007-1/15/2007 then 1/29/2007-1/31/2007)
ACM-CALCS–Manual
Page 44
unless the Source was truly idle for that period. CALCS will, however, allow more than one date
range within a month (1/1/2007-1/27/2007 then 1/28-1/31/2007), such as for change of contents
of a tank.
CALCS also allows overlapping Estimation dates (1/1/2007-1/31/2007 and 1/1/200712/31/2007), but it could cause confusion and should be avoided unless there is a real need to do
so.
4.8.2 Potential and Utilized Operating Hours
These values are used by CALCS in conjunction with the Formulas. The Formula calculates
pounds per hour. The Calculate function multiplies the resulting pounds per hour by the
Potential or Utilized Operating Hours to get tons per year, depending on whether the Formula is
for Actual or Maximum (Potential-to-Emit) emissions. CALCS computes a default product of
24 hours per day times the number of days within the Estimation dates. These hours can be
overwritten manually if desired.
4.8.3 Tabs
Sources have more parameters than can be shown in one view. The Sources screen has two to
four tabs with different data views, but all tabs are just parts of a single record. When you click
save, you save data on all tabs at once.
4.8.3.1
General Tab
The General tab shows the Source’s General Description, Specific Description, Unit, Profile and
sometimes the date range and comment button.
4.8.3.1.1 General Description Field
You can type any General Description you wish, except for Storage Tanks, which will be
explained shortly. The General Description has a “specific” meaning in relation to the Formula
and Profile screens for some Source Types. Any General Description you type in the Sources
screen, such as VENT, will then be on the pick list for General Description in the Formula and
Profile screens.
For User Defined Sources, there are seven fields in the Source screen with user defined labels
ACM-CALCS–Manual
Page 45
before and after the quantity. So, you would enter a label, then a quantity, then a label, like
“FLOW – 8500 – CFM”. These labels are not already in the Formula pick-lists. You must pick
VENT from the General Description pick-list in the Formula screen. Then the Formulas screen
will show FLOW with units of CFM available for use in a Formula.
The term VENT will now also appear in the General Description pick list for other User Defined
Sources, so you can select VENT again for another Source if you know the labels will be the
same.
For Storage Tank Sources, you cannot type in a General Description. You can only pick from
the hard coded list. The choices are Domed External Floating Roof, External Floating Roof,
Horizontal Fixed Roof, Internal Floating Roof and Vertical Fixed Roof. When one of these is
picked in the Sources screen, CALCS will present the tabs and fields appropriate for that tank
type. Likewise, the Formulas and Profiles screens will have a pick list of the appropriate
parameters.
4.8.3.1.2 Specific Description Field
The Specific Description is a comments field to type anything you want to further identify the
Source. This field is 25 characters long and often appears on reports next to the Source ID/FIN.
4.8.3.1.3 Unit Field
This links the Source to its Unit. Use the drop-down arrow to pick the Unit for the Source. If
the Unit is not on the pick list, you must add it in the Units screen.
4.8.3.1.4 Profile Field
The Source must be linked to a Profile, which contains the emission Formulas. Use the dropdown arrow to pick the Profile that has the Formulas for this Source. If the Profile is not on the
pick list, it must be added in the Profiles screen.
4.8.3.1.5 Comment Button
The Comment button is either found on the General or Detail tab. Click the button to open a
Comment field, type comments and click OK. This field is useful to document the basis for
calculations.
The first three lines of comments will appear on the Emission Calculation Parameters report.
This report is often useful to send the agency, when they ask for calculation methods. For this
reason, type your “public” comments on these first three lines. Hit Enter until beyond the first
three lines to enter confidential comments.
ACM-CALCS–Manual
Page 46
4.8.3.2
Detail Tab
This tab contains details about the Source itself. Contents of these tabs vary by Source Type.
Various versions of the Detail tab are shown in later sections.
4.8.3.2.1 Manually Entered Emissions Button
If pound-per-hour emission rates are already known without calculating, you can enter them
directly. If there is more than one Stream, highlight the desired Stream. Click the Manually
Entered Emissions button on the Detail tab. The screen below will pop up. Select the
Compound emitted, enter the lb/hr and any Comments and click OK. You can also Insert or
Delete individual lines. The Compound must be in the Stream Properties screen for it to save
emissions to the database.
ACM-CALCS–Manual
Page 47
4.8.3.2.2
Detail Tab – Air Stripper Source Type
The Air Stripper Source screen assumes a gas like air is stripping VOC from a liquid
like water. You can enter the Stream Processed, Flow Rate, Inlet VOC Concentration,
Sand Filter Effluent VOC Concentration and Outlet VOC Concentration.
ACM-CALCS–Manual
Page 48
4.8.3.2.3
Detail Tab – Catalyst Handling Source Type
For Catalyst Handling, the Catalyst Type is the Unit/Stream. CALCS automatically converts the
Unloaded Amount to pounds in the Cvt Unloaded Amount blank depending upon the Unloaded
Units of measure picked.
ACM-CALCS–Manual
Page 49
4.8.3.2.4 Detail Tab – Combustion Source Type
A Combustion Source could be external combustion like a boiler or internal combustion like an
engine. The Potential and Utilized Horsepower are for the later. The Fuel Type Combusted is
the Unit/Stream. Cvt Fuel Usage, Current Firing Rate and NOx Load Reduction Factor are
automatically computed by CALCS and can be referenced in a Formula later.
ACM-CALCS–Manual
Page 50
4.8.3.2.5
Detail Tab – Cooling Tower Source Type
The fields below are mostly self-explanatory. The Plant Feed Amount has reference to AP-42
Table 5.1-2, footnote (b). It says if you don’t know a refinery’s cooling tower circulation rate, it
could be approximated as 40 times the crude oil feed rate to the atmospheric distillation column,
in the same units.
ACM-CALCS–Manual
Page 51
4.8.3.2.6
Detail Tab – Drains, Sumps and Junction Box Source Type
The fields in the screen print below are self-explanatory.
ACM-CALCS–Manual
Page 52
4.8.3.2.7
Detail Tab –Equipment Leak Source Type
For Equipment Leaks, you can enter multiple Streams by clicking the Insert button at the bottom.
Highlight a line and click the Delete button to remove it. The Streams can be different for each
date range. Each Stream can also have different hours within the same pipe or equipment.
Although the note below the Stream list says “combined Streams should add up to 100%”, it is
not necessary unless designed that way in the Formula. The days and hours need not match
unless the Formula references both.
The Leak Counts tab will be discussed in the Leak Counts section and in the Equipment Leaks
chapter.
ACM-CALCS–Manual

4.8.3.2.8
Detail Tab –Fluid Catalytic Cracking Unit Source Type
This screen is mostly self-explanatory. The Type of Flue Gas is the Unit/Stream.
ACM-CALCS–Manual
Page 54
4.8.3.2.9
Detail Tab –Flare Source Type
In the screen below, the Flared Units drop-down is expanded to show options. TPE means tons
per estimation period. Although the Flare Efficiency field is presented for flexibility, it is still
best to enter this efficiency in PIPELINE or EI.
Note that the flare is not the source of the VOC it burns. The VOC source(s) are somewhere
upstream, and the flare is only the abatement device. The flare is the source of NOx, CO, SO2
and PM from the flame itself.
ACM-CALCS–Manual
Page 55
4.8.3.2.10 Detail Tab –Loading Rack Source Type
The Loading Rack Source Type can pertain to loading of barges, rail cars, trucks or even drums.
This screen can accommodate any number of Streams (under Product type). Streams can be
changed for every set of Estimation Dates entered. Enter the Throughput and Units, and CALCS
will compute Cvt (Converted) Throughput in standard “Mgal” units. Click Insert or Delete
buttons at the bottom to add or remove Streams.
Highlight a Stream and click Calc TVP to calculate true vapor pressure. This function only
works if all Compounds in the Stream have vapor pressure data and Stream temperature. See the
next page.
The %Control Efficiency is allowed here for the case where some liquids are controlled and
others are not. If the Source is always controlled, it is better to enter the efficiency in Pipeline or
EI modules.

Scrolling farther to the right you can see other variables that can be added. Average Temp (F)
must be entered to use the Calc TVP button, which calculates the true Average Vapor Press
(psia). CALCS also automatically enters the Days Online and Operating Hours from the
Estimation Dates, assuming 24-hour-per-day operation.

4.8.3.2.11 Detail Tab –Oil/Water Separator Source Type
An Oil/Water Separator or more specifically a VOC/Water Separator is a tank or basin with
baffles to trap floating VOC on a wastewater Stream by simple gravity separation. VOC
evaporation can be controlled by a cover and/or other control device or may be open and
uncontrolled. The radio buttons for the choice of control only generate a label to that effect in
reports. They do not change calculations. The Flow Rate in Gal/min is the water flow rate.
Concentration of VOC must be entered in the Stream Properties screen.
ACM-CALCS–Manual
Page 58
4.8.3.2.12 Details Tab – Spills Source Type
VOC spills are calculated from the Spill Amount, Spill Units and Percent Vaporized.
ACM-CALCS–Manual
Page 59
4.8.3.2.13 Detail Tab – Storage Tank Source Type
The Product is the Unit/Stream, which you must pick from the list. Pick the State and closest
City for meteorological data.
If the Compounds in Stream Properties have vapor pressure data, you can click the Vapor
Pressures button to automatically calculate Daily Minimum, Average and Maximum Liquid
Vapor Pressures. These values are then used in the standard AP-42 Formula. If the Constant
Temperature Tank radio button is clicked Yes, it sets the Daily Vapor Temperature Range to
zero, which zeroes out the daily breathing losses in the standard AP-42 formula.
The four pick lists on the right side will automatically show monthly or annual Maximum
Ambient Temperature, Minimum Ambient Temperature, Insolation Factor (solar heating) and
Wind Speed for the chosen city. CALCS uses these to compute Daily Average Liquid Surface
Temperature and Daily Vapor Temperature Range.
Due to the number of variables in the AP-42 tank formulas, CALCS has an additional Tank Data
tab. See the Tank Data Tab section for details.
ACM-CALCS–Manual

4.8.3.2.14 Detail Tab – Sulfur Recovery Source Type
Enter the sulfur Recovery Efficiency, Sulfur Produced and Produced Units in Long Tons Per
Day (LTPD), Short Tons Per Day (STPD), Long Tons Per Estimation Period (LTPE) or Short
Tons Per Estimation Period (STPE). Enter Tail Gas Emitted and Emitted Units in lb/hr or Tons
Per Estimation Period (TPE). CALCS automatically converts both quantities to STPE and TPE,
respectively. Pick the CEM type (either H2S or SO2) and enter the CEM Concentration for that
period. Pick the Unit/Stream for the Type of Exit Flue Gas.
ACM-CALCS–Manual
Page 61
4.8.3.2.15 Detail Tab – User Defined Source Type
If a Source either does not fall into one of the other Source Types, or the desired data fields are
not found there, you can create your own set of up to seven parameters under the User Defined
Source Type. Each of the seven parameters has three fields, a label, a number and a label. This
can be used for a name for the parameter, a quantity and the units of measure. The Formula can
be set up to read these fields as desired. The example below is a degreaser (solvent parts washer)
with the inches of solvent added during the period, the width and length of the degreaser and the
density of the solvent. The Formula calculates the pounds of solvent added (emitted) from those.
ACM-CALCS–Manual
Page 62
4.8.3.2.16 Detail Tab – Wastewater Source Type
VOC often evaporates from wastewater. Pick the Stream, the Flow Rate and the Flow Rate
Units. CALCS will automatically convert the flow to thousands of gallons per estimation period
for use in the Formula. The Stream Properties must contain the VOC Compounds and
concentration.
ACM-CALCS–Manual

4.8.3.3
Tank Data Tab
This tab was added because of the number of fields needed to enter the many variables used by
the standard AP-42 formulas. The tab varies by tank type. The five tank types in CALCS are in
the General Description pick list as follows: Horizontal Fixed Roof, Vertical Fixed Roof,
Internal Floating Roof, External Floating Roof and Domed External Floating Roof. No other
General Description is available for the Storage Tanks Source Type.
4.8.3.3.1
Tank Data Tab – Horizontal Fixed Roof Tanks
Tank dimensions, Throughput with units, shell and roof colors (see second small screen print)
and Liquid Type can be entered or selected. Ambient Atmospheric Pressure can be entered
depending on the height above sea level. Items on the right can be calculated automatically by
clicking the button, or they can be entered manually. The pressure and vacuum settings of vapor
conservation vents can also be entered. Pumping rate can be used to determine maximum hourly
emissions. If the Constant Level Tank radio button is clicked “Yes”, the working losses will go
to zero in the standard AP-42 formula.
ACM-CALCS–Manual
Page 64
The shell and roof paint color factors can be picked from drop-down lists.
ACM-CALCS–Manual
Page 65
4.8.3.3.2
Tank Data Tab – Vertical Fixed Roof Tank Type
The Vertical tank data is the same as that of the Horizontal tank, except the Shell Length is now
Shell Height, and there is a dome or cone roof option. The Vapor Space Outage is automatically
calculated depending on the roof type.
ACM-CALCS–Manual
Page 66
4.8.3.3.3
Tank Data Tab – Internal Floating Roof Tank Type
Additional fields are offered for this tank type as seen in the screen print below. Many fields
have pick lists. Others have buttons for automatic calculation. The Total Deck Fitting Loss
Factor is carried forward from the tab labeled Tank Fittings. See Tank Fittings section for
details.
ACM-CALCS–Manual
Page 67
4.8.3.3.4
Tank Data Tab – External Floating Roof Tank Type
External Floating Roofs have the same data as Internal Floating Roofs except for the added Seal
Wind Speed Exponent, n. The Total Deck Fitting Loss Factor is carried forward from the tab
labeled Tank Fittings. See Tank Fittings section for details.
ACM-CALCS–Manual
Page 68
4.8.3.3.5 Tank Data Tab – Domed External Floating Roof Tank Type
Data fields for this type tank are seen below. The Total Deck Fitting Loss Factor is carried
forward from the tab labeled Tank Fittings. See Tank Fittings section for details.
4.8.3.4
Tank Fittings Tab
This tab appears for Internal Floating Roofs, External Floating Roofs and Domed External
Floating Roofs. It allows entry of the number of hatches, wells, etc.
4.8.3.4.1
Tank Fittings Tab – Internal Floating Roof Tank Type
This tab lists 44 fittings with their AP-42 emission rates. Note that the emissions are totaled at
the bottom. This total is carried over to the Tank Data tab for use by Formulas.
ACM-CALCS–Manual
Page 69
4.8.3.4.2
Tank Fittings Tab – External Floating Roof Tank Type
The Tank Fittings tab for this type roof has the same choice of fittings.
Scrolling to the right, you can see that CALCS automatically computes four related factors.
ACM-CALCS–Manual
Page 70
4.8.3.4.3 Tank Fittings Tab – Domed External Floating Roof Tank Type
These fields for Domed External Roofs are the same as for Internal Floating Roofs.
ACM-CALCS–Manual
Page 71
4.8.3.5
Leak Counts Tab – Equipment Leaks Source Type
This has been used in the past to quantify all leak emissions. More recently, leak contractors
quantify all but non-monitored leaks, which are normally calculated here. For details on the
former method, see the separate Equipment Leaks chapter. Only the non-monitored functionality
will be explained in this section.
Multiple Streams can be entered on the Detail tab, each with its hours of presence within the
section of pipe or equipment defined by the Source ID. CALCS will list all components for each
separate Stream entered with a VOC of 100% on the Detail tab. If there are Streams with less
than 100% VOC, a single list of components for all those Streams will be under Combined
Streams <100% VOC. You can delete the entire component list for a given Stream by clicking
the Delete button at the top of that Streams list by the Steam ID.
For each Stream, enter the count of each non-monitored component in that section of pipe. This
count will be multiplied by an emission factor in pounds per hour per source (per component). A
different count can be entered for each Estimation Period for the same Source.
Then a Formula must be entered for each type of component with a component count in the
Source screen. The Profile must also contain all of those Formulas and be linked to the Source.
ACM-CALCS–Manual
Page 72
Although it will be explained more in the Equipment Leaks chapter, the Leak Ranges for each
component are listed in the following order, with leak analyzer reading ranges in parts per
million (ppm):
•
•
•
•
>=0 and <=0, which indicates “Zeros”
>=1 and <=1000000, indicating “Intermediates and Leakers”
>=0 and <=0, indicating “SOCMI average”
>=0 and <=1000000, indicating “Totals”
You will find a Leak Range pick list in a field in the Formulas screen with the same four choices.
The Source and Formula Leak Ranges must match. If you enter a count next to SOCMI Average
for a Source, you must later choose SOCMI Average in the Formula screen. Otherwise, the
Formula will not find the count:
ACM-CALCS–Manual
Page 73
4.8.4 Primary and Secondary Sources
When a Source is complicated or has multiple scenarios, such as a boiler that burns coal, oil and
gas, there may not be enough fields in the Sources screen to cover all possibilities. This would
also be the case for any Source for which the emissions must be calculated using more than one
Formula. CALCS can facilitate this by allowing several partial “Sources” to be linked together
as one total Source.
Suppose the boiler’s official ID reported to the state is BOIL1. First create a Source called
BOIL1 and calculate zero emissions by showing zero fuel usage. This will avoid confusion or
double counting later. Then create three more “Sources” named as you wish, like BOIL1COAL,
BOIL1OIL and BOIL1GAS. Enter the usage of each fuel under the respective Secondary
Source. You would later also create a Formula and Profile for each Secondary Source.
Then, with the Source screen open and, at a minimum, the Facility Code (site) selected, click
Options and Equipment Maintenance. Find BOIL1COAL in the left column. In the right
column select BOIL1 as its Primary Source. Repeat this for the other two Secondaries. Also,
find the Primary Source (BOIL1) in the left column and pick BOIL1 again in the right column.
CALCS now knows that a Source with its own ID on the right is a Primary Source, and a Source
with a different ID on the right is a Secondary Source.
Later, the Secondary Sources can have their emissions calculated, summed all together and the
total reported under the Primary Source. This will be discussed more in the Inventory Screen
section. Only the Primary will be transferred to the EI module for reporting, because the
PIPELINE module only transfers previously reported Source ID’s (FIN’s) to EI. The official
Sources will be “known” by PIPELINE and EI modules from the download file from the state,
which is first imported into the database. The diagram below shows Primary and Secondary
associations:

4.8.5 Special Menu Options
Some menu options are only available if certain screens are open.
4.8.5.1
Equipment Maintenance
When the Sources screen is open, you can click Options and Equipment Maintenance or Source
Reports. The Equipment Maintenance screen default is to show all Sources. You can click
Primary/Secondary to see just those Sources that are thus linked, and then you can click Full List
to view all Sources. Primaries and their related Secondaries are grouped with the Primary
highlighted in black. The Equipment ID (Source ID) is in the left column. If it has no
Primary/Secondary relationship, the right column will be blank. A Secondary Source will show
its Primary Source ID in the right column. The Primary will have its own Source ID again in the
right column. A drop-down arrow in the right column shows a list of Source ID’s to use as a
Primary Source. Click OK to save changes.
ACM-CALCS–Manual
Page 75
4.8.5.2
Source Report
When the Source screen is open, you can also click Options, Source Reports then Retrieve for a
list of all Sources with their Source Type, General Description, Specific Description, Unit and
Profile.
ACM-CALCS–Manual
Page 76
4.9 Quick Edit Screen
Click on the drop-down arrow just to the right of the Sources button. Select Quick Edit. The
Quick Edit screen allows entering throughput and other data in a list, rather than on one the
Source screen at a time. Each line of data is for a Source for a specific time period. Not all
process variables are displayed on the Quick Edit screen. In general, only the variable(s) that are
likely to change from one period to the next, such as throughput or fuel usage, are editable. Pick
the Facility, Source Type, (Unit only if desired) and Year and click List. Edit data and click
Save.
Click Export to save the list as a spreadsheet (normally Excel5 with headers) or some other file
type. Then edit the spreadsheet, delete the column headers, remove times from dates if required
(change 1/1/2007 00:00:00 to 1/1/2007) and save as a tab delimited text file. Then you can reimport the edited file by clicking the Load File button, browsing for the file and clicking OK and
the Save button. This can, of course, be imported from a throughput spreadsheet other than an
exported one if you use the same format.
ACM-CALCS–Manual
Page 77
4.10 Import Screen
This differs from the Quick Edit import function in that this screen is used to import Manually
Entered Emissions. Again, this is faster than editing them one Source at a time on the Detail
screen. Click the drop-down just to the right of the Sources button, then on the Load File toolbar
item. You will be prompted to locate the upload file. The data file can only be a Tab-delimited
text file, such as from a spreadsheet using the Save As option. The column order in the data file
should match the order in which the columns appear on the screen. The first column in the file
should be the Source ID. Once the data file has been loaded successfully, you can click on the
Import button to save the data into the database. All records that are saved successfully will
disappear from the list. The remaining records should be examined for errors. There could be
various reasons for a record being rejected. The record could be one that already exists in the
database and you did not choose to overwrite it. An invalid Stream, CAS ID or Source ID will
also lead to rejection. You can also use buttons to manually Insert or Delete lines or
Find/Replace before Importing or to Print.
ACM-CALCS–Manual
Page 78
4.11 Formula Screen
Formulas use variables from fields in the Compounds, Stream Properties, Unit/Stream and
Sources screens to calculate emissions. Click the Formulas button to access this screen. To add
a Formula, type a new ID in the blank to the right of Enter Factor ID. To find an existing
Formula, select the Source Type and the Factor (Formula) ID from pick lists.
The object of a Formula is to calculate pounds per hour of emissions from the Source. You will
not normally consider abatement or individual stacks at this time. The Calculate function will
later automatically multiply the pounds per hour by the hours entered in the Source screen to
compute tons per estimation period.
The Formula should calculate pounds per hour before controls. While abatement efficiency can
be entered into a Formula, it may not be the same one entered in the EI module for reporting.
This inconsistency would later cause confusion. It is best to let CALCS compute the unabated
emissions and let the PIPELINE module transfer them to the EI module. The PIPELINE later
ACM-CALCS–Manual
Page 79
uses the efficiency entered in EI. One exception is a Loading Rack Source that abates gasoline
but not diesel loaded from the same rack. The control efficiency must be entered in the Source
screen for each Stream and the Formula must contain the efficiency as a variable. You must,
however, check the efficiency entered in the EI module for consistency.
To enter a new Formula, select the Source Type and enter a Factor ID of 10 characters or less
and a Specific Description of your choosing. Then pick the General Description and Compound
emitted (like NOx) from the pick lists. Enter an Emission Factor such as 100 (or 1 if all
coefficients are to be in the Formula), pick or enter the EF (emission factor) Units such as
lb/MMBtu and type in the Data Source. The EF Units and Data Source will show up in certain
reports when using the Calculate button. The number entered for Emission Factor will be
plugged into the variable “ef” in the Formula block below.
4.11.1
General versus Site-Specific Formulas
The Type of Factor can either be General or Site Specific. An AP-42 formula would be an
example of a General Formula to be used at multiple sites and not likely edited. A General
Formula can be locked to prevent editing by closing all but the main screen, clicking
Maintenance then Disable Formula Edit. A Site Specific Formula cannot be locked. Click the
radio button by the desired Type Of Factor.
4.11.2
Maximum versus Actual Formulas
The Emission Type can be Actual or Maximum depending on the intent of the Formula. Click
the appropriate radio button. Normally you would choose Actual. The Formula must be entered
in such a way as to match the Emission Type.
4.11.3
Columns (Variables)
The Columns are data fields from previous screens for use in a Formula. If you single-click one
of these variables, you can see the abbreviation, explanation and units to the right. If you
double-click a variable, you will add it to the end of the Formula or wherever you place the
cursor in the bottom window.
To see more available variables in the Columns list, check the box for Stream Data or Stack Test.
Stream Data shows fields from the Stream Properties screen. Stack Test shows fields from
previously entered stack test data. Stack Test data is found with all screens closed (except the
main screen) on the Maintenance menu under Stack Tests.
ACM-CALCS–Manual
Page 80
4.11.4
Operators, Powers, Parentheses and Embedding
Operators (+, -, *, and /), powers (1E and xy) and parenthesis buttons can be clicked between
entering variables. The Embed Formula button presents a list (see screen print) of Formulas
already saved, which you can insert within the current Formula.
When the Formula is complete, click Save. Click Comments to keep a backup copy of a long
Formula, to explain variables or enter the basis for calculations. Keep in mind that it is possible
to put a variable in a Formula for which you did not enter data on a previous screen. This will
generate an error message during the Calculate step.
ACM-CALCS–Manual
Page 81
4.11.5
Equipment Leak Formulas
The Formula screen for Equipment Leaks looks different from that of the other Source Types.
Instead of selecting a Compound, the Compound is assumed by CALCS to be total VOC. That
VOC can be speciated later in the Profile. Instead of each Compound having a separate Formula,
each Component has its own Formula. The Emission Factor is from AP-42 or a Site-specific
factor in pounds per hour per Component (lbs/hr-source).
The Type of Factor must be specified – either Correlation Equation or Emission Factor.
Correlation Equations will be discussed in the separate Equipment Leaks chapter. Since most
monitoring is done by contractors, only the unmonitored Emission Factor Formula is discussed
here.
Enter the Emission Factor and create a Formula, normally “ef * leak_count”, which multiples the
emissions per Component by the number of Components previously entered in the Source
screen. Enter the same Monitoring Program that was entered in the Sources screen. Also, enter
the same Range Group in the Formula screen as the one where component count was entered in
the Source screen. In other words, if you entered the Component count in the Source screen next
to SOCMI Average, you must choose SOCMI Average in the Formula screen. This is explained
above in the Source screen – Leak Counts tab section. Enter a Stream Category if one is used.
ACM-CALCS–Manual
Page 82
4.12 Profile Screen
A Profile is a list of Formulas or Manually Entered Emissions and their speciations. A single
Profile can be related to more than one Source. A Profile ID and Description of the user’s choice
is entered. The Profile ID is linked to the Source screen on the General tab.
4.12.1
Using Vapor Phase Concentration
You have the option to Use Vapor Phase Concentration (of Compounds in the Stream Properties)
or not. This may cause calculating errors if the Stream Properties shows the Composition Phase
as “vapor” and the Profile “Use Vapor Phase Concentration” is marked “No”. Sufficient
Compound and Stream Properties data must be entered to use this function.
ACM-CALCS–Manual
Page 83
4.12.2
Estimation Method
This adds an emission calculation method to the Profile list at the bottom of the screen. There
are three options. Click the drop-down arrow and click Site Specific Formula, General Formula,
or Manually Entered Emissions. If you have a Formula to use, select one of the first two. If you
Manually Entered Emissions in the Source screen, choose the latter.
A second window will pop up with a list of Formulas you can add to the Profile.
ACM-CALCS–Manual
Page 84
When choosing Manually Entered Emissions, a line appears at the bottom. Use the pick list on
that line to select the Compound.
Add as many Formulas and Manually Entered Emissions as needed.
4.12.3
Speciation
If the Formula calculates Total VOC, a Multiple Compound, it may be necessary to divide it into
species or Compounds. Likewise, SOx could be speciated into SO2 and SO3, PM into various
metals, etc. There are three ways to do this: by Manual selection, by Compound List or by
Stream Composition. The latter two methods allow adding many Compounds at a time.
For CALCS to compute every Compound’s emissions, you must have every Compound listed in
the Profile. Also, before Speciation, you must first have added a Formula for a Multiple
Compound like VOC, PM, SOx, etc. to have something to speciate.
ACM-CALCS–Manual
Page 85
If you click the Speciation drop-down arrow and “Compositional Analysis – Manual”, a window
will pop up asking you if it is VOC, PM, etc.
Then a new row will be added to the bottom of the Profile list. Pick the Compound.
ACM-CALCS–Manual
Page 86
For Speciation from a Compound List, you must first have created a Compound List. The
Compound List section above shows how to create such a list. You must have also have added a
Formula for VOC, etc. to have something to speciate. With both of those done, you can click the
Speciation drop-down arrow, click “Compositional Analysis – Using a List”, choose the
chemical family and choose a list.
Either Select All to add the whole Compound List to the Profile, or click Compounds
individually while holding down the Control Key and click OK.
ACM-CALCS–Manual
Page 87
For Speciation from a Stream Composition, you should have already created a Stream
Composition (Property) and Unit/Stream earlier, and you must have already added a Formula for
a Multiple Compound like VOC to speciate. Click the Speciation drop-down arrow and
“Compositional Analysis – Using a Stream Comp”, select the chemical family. In the next
window pick the Stream ID.
Either Select All or click Compounds individually and click OK.

Equipment Leak Monitoring Program
If this is for an Equipment Leak Source Type, select the same Monitoring Program that you
selected in the Sources screen.
The choices of Monitoring Programs are created with all screens closed by choosing the
Reference menu, Equipment Leak Reference Data and Leak Monitoring Programs.
4.12.5
Linking the Profile to the Source
After creating a Profile, you must go back to the Source screen General tab and select that Profile
from the pick list and Save to link it to the Source.

4.13 Calculate Screen
When all previous screens have been linked, you can click the Calculate button. When you
choose a Source and click Run, the results are simultaneously displayed and saved to the
database for that Source/Date Range combination. If you edit a Formula or its variables and
click Run again, it will overwrite the old results with the new results. Repeat the edits as many
times as needed to create a final draft, so to speak.
Calculated results can later be transferred by the PIPELINE module to the EI module for
reporting to the agency. You can think of the database as being in three parts: CALCS raw data,
CALCS draft results and EI reportable results.

Selecting What You Calculate
Select a Facility (Site) ID, a Begin Date, an End Date, a Source Type a Unit only if you want to
narrow the Source search and the Source (Equipment ID). You must check the box by Unit or
Equipment ID to see the filtered list.
4.13.2
Calculation Criteria
When you Calculate the first time, use the default Calc Emission Results and Calc Vapor Weight
% options. If you later want to see earlier results that were previously Calculated, you can check
the box for Use Existing Results, which is faster than recalculating. If you later re-Calculated
with a new Profile and want to see or re-Calculate old results, check the box called Use Profile
Matching Selected Time Period.
When Calculation Criteria are set, click the Run button. That will show you the results and write
them to the database simultaneously.

4.13.3
Other Report Variations
If you check the box for Compound List, you can pick a previously constructed list of
Compounds by the name of the list. Then, when you click Run, you will Calculate only the
emissions of those Compounds.
Calculate also produces useful internal reports for a management. Before clicking Run, if you
want to add your own explanation to the recipient, check the User-Defined Report Heading box
and type a special heading.
4.13.4
Calculate Button Row
The Run button performs whatever calculation you specify in the Calculate screen, displays them
in a results screen (see below) and writes the results to the database.
After results are Run, you can use the PIPELINE Module to distribute FIN emissions to EPNs,
add abatement and transfer (Pipe) them to the EI module to for reporting.
The Save As button will save the results as a file of your choosing, such as a spreadsheet. The
Zoom Report button toggles back and forth between the results screen and the main Calculate
screen. Prior and Next buttons thumb through the results pages. You can also use the Print or
Close buttons.

Options
Before clicking Run, you can also click Options at the top of the screen to show a menu of report
styles. General Reports has six options of varying detail. The default report is Source Generic.
The most detailed report is Emissions Calculation Parameters, which shows the Formula and
variables used to Calculate the results. This is useful to send to the agency if they ask for the
basis of previously reported emissions.
Process Unit Reports opens the options shown below. The SARA Compounds must be checked

4.14 Inventory Screen
The Emission Inventory Summary is a data table that contains all of the emissions for all Sources
and date ranges that have been Calculated by the user, along with critical explanatory
information. After running Calculate, the Inventory Screen shows you numerous Sources in
spreadsheet view. You can edit results individually and sum Secondary Sources for reporting as
the Primary Source ID. The Inventory Screen looks much like the Calculate screen.
ACM-CALCS–Manual
Page 96
You make a selection the same way as you do for Calculate and click Retrieve to get the
following listing. Emissions appear by Source, date range and Compound but can be sorted by
clicking any column heading.
Multiple rows may be selected by clicking one row and then selecting another row while holding
down the <Shift> key. Click on the Delete icon to delete any highlighted rows.
You may also enter Permit limit and reference data into rows of the Emissions Inventory
Summary window after moving the horizontal scroll bar to the right.
ACM-CALCS–Manual
Page 97
If the user has not taken the time to set up Secondary Sources and their relationship to Primary
Sources in advance but still wishes to sum emissions, a feature is available for meeting this
objective. By double-clicking on any row in the Emissions Inventory Summary window, a
window with four different options is presented to the user to assist him in finding the emissions
that will be summed.
Regardless of the summing technique, any summed emission records in the Emissions Inventory
Summary window are automatically displayed with a gray highlight, and a Summed note is
entered into the comment column of the Inventory data table.
You can edit or Delete results and Save. The Search Criteria button takes you back to the main
Inventory screen.
ACM-CALCS–Manual
Page 98
4.14.1
Data Menu for Primary and Secondary Sources
If you have Secondary Sources linked to Primary Sources, the Secondary Sources probably still
have the Calculated subtotal emissions and the Primary Source has zero emissions. To sum all
Secondary Source emissions and assign the total to the Primary Source, click Data at the top of
the screen, then Sum Emissions.
The following screen will open. It lists all Primary Sources that have Secondary Sources. Click
on a Primary Source to see its Secondaries at the bottom or click Select All Primary Sources.
Normally you would then click Sum And Delete Emissions to sum the emissions of all
Secondaries, assign the total to the Primary and delete the original subtotals in all the
Secondaries. That will prevent double counting later.
In special cases, you may click Sum And Restore Emissions, which sums the emissions of all
Secondaries, assigns the total to the Primary and restores (leaves) the subtotals in the
Secondaries. If you check the box at the upper right, you can Remove Zero Emission records
ACM-CALCS–Manual

from the totals, which is the normally recommended default.
Now the PIPELINE module can transfer just the emissions of the Primary to EI module. The
Secondary Sources will not be transferred or reported.

CHAPTER 5: PIPELINE MODULE
5.1 Main Screen
The data PIPELINE is a module designed to copy Calculated emissions from the CALCS
module to the Emission Inventory (EI) module. It is accessed by selecting the PIPELINE icon
from the COMPASS folder on the Start menu. As shown below, the main tool bar enables
choices to be made as to whether to “Pipe” equipment parameters or emissions, as well as
whether to run maintenance functions such as for equipment relationships or contaminants. Most
users will use this feature to copy emissions data only.

5.2 Parameter Screen
Click the Parameter button on the main screen. This screen is used to transfer only the Source
parameters from CALCS to the EI module. No emissions will be “piped”. Instructions are on
the screen itself.
ACM-CALCS–Manual
Page 102
5.3 Emissions Screen
This screen is used to “Pipe” emissions from CALCS to EI. Click the Emissions button. Pick the
Year, Facility, and Source ID. Pick the Unit and Source Type only if desired to reduce the size
of the pick list of Source IDs. Click the List button to get the view below.
In addition to copying emissions, the PIPELINE feature also applies control efficiencies for all
connected control devices and prorates emissions to connected emission points. Selections are
available to turn these special processing functions on or off. The Use Ozone feature in the
Equipment screen allows calculation of pounds-per-ozone day, but this is best done globally
under Emissions Maintenance and Global Maintenance in the EI module later.
The Zero Out option will change all actual emission rate values to “0” before the PIPELINE is
done, including emissions that are not affected directly by the PIPELINE. Otherwise, if this
checkbox is left blank, emissions that are not affected by the PIPELINE will retain their current
emission rate value.
Check all three Error Reports and resolve any errors before clicking the Pipe button. Highlight
the emissions that you want to be copied to EI, or leave it as-is if all are to be copied. Then click
the Pipe button to transfer emissions to the EI module.

5.3.1 Error Reports
Review all three Error Reports before Piping emissions to the EI module. First click the Err
Reports button.
5.3.1.1
Equipment Error Report
The default first report is the Equipment Report. If a Source ID from CALCS does not match
any FIN in the EI module, its emissions cannot be Piped to the EI module. The CALCS exercise
in an earlier chapter produced the error shown below, because the Source ID was arbitrary and
not in EI. The EI module gets its list of previously reported FINs after you import the state
download (Extract) file using the Utilities module, which is normally done by this point. Error
corrections are explained in the Troubleshooting chapter.
5.3.1.2
Percent Flow Report
If a FIN’s emission percentages to EPNs are missing, it cannot be Piped, and an error will
appear. Click the drop-down arrow to select the Percent Flow Report. As shown below, this
error is rare. Any error can be corrected as explained in the Troubleshooting chapter.
ACM-CALCS–Manual
Page 104
5.3.1.3
CAS Number Report
If you add a CAS number in CALCS that is not in EI, the PIPELINE module cannot transfer
emissions for that contaminant. That error will appear on the CAS Number Report listing the
CAS number and the related Source and other data. This error is corrected as described in the
Troubleshooting chapter. If no emissions are associated with the error, it may be ignored.
The default (recommended) setting is not to Pipe total VOC, because EI will create its own total
VOC number from the sum of individual Compounds. Thus, VOC will appear as an error,
because it wasn’t Piped, but it can be ignored in this case.
ACM-CALCS–Manual
Page 105
5.4 Contaminant Screen
Click the Contam button to open the screen below. Click List to show all Contaminants. To
create a narrower list, enter the first few digits of the 5-digit Texas Contaminant code to the
right, then click List. If you don’t know the Contaminant Code, click the drop-down arrow and
pick Contaminant Name Like or CAS Number Like, type in the first few characters and click
List. CALCS emissions must use the CAS numbers shown in this list to be able to Pipe
emissions to the EI module. This screen is also accessible from the EI module by clicking File
and Contaminant Maintenance.
ACM-CALCS–Manual
Page 106
5.5 Equipment Screen
FIN-EPN-CIN relationships must be established before CALCS emissions can be Piped, because
CALCS only “knows” the total emissions from a FIN. CALCS does not “know” what EPN or
EPNs will exhaust the emissions, the percentage to each EPN, whether there is a CIN or what its
efficiency is. These relationships are normally imported from the state download file.
Click the Equip and List buttons to see all relationships. To see a smaller list, type the first few
characters of the FIN to the right of Facility ID Number Like. As an option, use the drop-down
arrow to pick Emission Point Number Like or Control Device ID Like, type a few characters and
click List. This screen is also viewable from the EI module by clicking File and Equipment
Relationships.
ACM-CALCS–Manual
Page 107
There must be one line per FIN-EPN-CIN combination. If FIN1 exhausts partly through EPN1
and CIN1 and partly through EPN2 with no CIN, there must be a line for FIN1-EPN1-CIN1 and
another line for FIN1-EPN2 with no CIN.
If you want to add an EPN to a FIN, click Insert to receive a blank line. Use drop-down arrows
to pick FINs, EPNs and CINs. If there is no CIN, select the hyphen (-) rather than leaving a
blank. The Feeding CIN column is for a second CIN in series, where CIN1 is “feeding” CIN2.
To add or edit a CIN, right click the line where the CIN belongs. A window will pop up to allow
you to add or edit. Note the small Add Control Device/Edit Control Device box in the screen
below.

5.6 Rename Screen
Click the Rename button to open the screen. If a Source ID in CALCS does not match the FIN
in EI, you can use the pick list to rename the Source ID for PIPELINE transfer purposes. Then
click Save.
This feature may not be used to add new Sources in PIPELINE or EI, nor can it change Source
ID’s in EI.

CHAPTER 6: EQUIPMENT LEAKS
6.1 Calculating Equipment Leaks
Equipment Leak (or Fugitive) emissions data is usually supplied by a contractor. The user is
responsible for creating the links between certain fields in both CALCS and the corresponding
fields in the Source data files. The system has capabilities to import the data provided by the
contractor, as long as the format that is used for this import procedure matches the format for
which this feature was written (call PDC for details).
There are several files needed for import. The first set of files imported will be the ‘leakers’ files
that CALCS uses to enter in the component counts. The next set of files is the Totals file that
CALCS uses to keep track of the total number of components in the facility. The total number of
components and the number of zero leakers are determined by CALCS after processing this file.
Once the data is imported, you set up equations in CALCS and Calculate emissions. If you used
correlation equations, CALCS will need to import the ‘leakers’ file again to input the specific
leak rates into the equations.
6.2 Setting Up the Data
Before importing contractor data, you must first set up CALCS to accept the data for import.
You will need to perform the following steps before attempting to import Equipment Leak
contractor data:
Step 1: Make sure all the process Units are entered.
Step 2: Define all the chemicals and Compounds that will be needed for speciation of the
Stream data.
Step 3: Define all your Streams, and enter the Stream Compositions in this window.
Step 4: Link the Streams to each process Unit in this window by inputting the first four
columns. Also, the Leak contractor Stream ID and the Equipment Leak Stream
category columns are necessary when importing data. If you will be speciating your
VOC, the TVP and Deg F columns also need to be entered. The columns for Stream
phase, VOC service, and TVP@68F are optional.
Step 5: To access these screens from the main window choose Reference, Equipment Leak
Reference Data. Before continuing on to the Source window, make sure you fill in
the Leak Ranges, Leak Component Types, Leak Monitoring Programs, and Stream
Categories. CALCS uses the Leak Ranges and Leak Component Types information
in Sources to construct the Leak Count table for Equipment Leaks, so it is important
that you consider what leak ranges you will need and the components to be
monitored before proceeding.
Step 6: Consider each process Unit as an Emission Source for fugitives. List the Streams
within each process Unit that are monitored for fugitive emissions. The estimation
ACM-CALCS–Manual
Page 111
dates should correspond to the frequency of the contractor data.
If the contractor supplies data for each month (which is probably the most
common), each Source should have 12 sets of records with different Estimation
Dates (i.e. 01/01/2007–01/31/2007, 02/01/2007–02/28/2007. 03/01/2007–
03/31/2007, and so on). When you access the Leak Counts table, CALCS constructs
a table that includes all the information identifying the components in each Stream.
The Leak Counts column will be blank. When you import the data, the Leak Counts
column will be filled in for you.
TIP: If you choose to have multiple estimation dates (i.e. monthly), then
only set up one estimation period (i.e. one month) and import the first
month's contractor files. If errors are found, then you can correct the errors
in that month's record. Once you have imported the files for one month, go
ahead and save the emission Source for the remaining 11 months. This way,
each file will have the corrections already saved. This will save you a large
amount of time if errors are found.
Step 7: From the main window choose Reference, Equipment Leak Contractor Data. These
windows must be filled out so that the imported data will correspond correctly to
the data in CALCS.
Step 8: Create an emission factor or correlation equation for each range group, monitoring
program, component type, and Stream category. A correlation equation calculates
emissions by considering the actual ppm leak rate concentration of each component.
An emission factor estimates emissions by considering the number of components.
Both methods may be used. Be sure to select the radio button on the upper right
corner of the screen that corresponds to either "Emission Factor" or "Correlation
Equation". For the monitoring program, you may select "ALL" if the
factor/correlation equation works for all the programs entered in Reference,
Equipment Leak Reference Data, Monitoring Programs. For the equation, if you
want to raise a number to a power, select the "^" button on the square button to the
left of the equation box. When "^" is selected, the Formula "f_exp(x,y)" will appear,
which represents xy. You need to replace the x and y with the actual values. For
3
0.82
would be ‘f_exp(leak_rate,
instance, 5 would be ‘f_exp(5,3)’ and (leak_rate)
0.82)’.
Step 9: Set up an Profile for calculating Equipment Leak emissions based on the factors set
up in Formulas. When selecting estimation methods, you may choose both
correlation equations and emission factors, which you may have set up for different
leak ranges in Step 8.
Step 10: Link each Source to the Profile. You may do this faster for Multiple Sources in the
Profiles window by selecting Options, Link Equipment.
6.3 Importing Contractor Data
The second file is a listing of the total number of components by Stream in the plant during that
estimation period. The information must be in a specific format.
From the main window, select Reference, Equipment Leak Contractor Data, Import and Process
ACM-CALCS–Manual
Page 112
Leak Counts. This will bring up the Import window.
6.3.1 Leakers
Always enter the Leakers file first!
1. Enter the leak time period covered by the file to be imported. (Note only one file can be
imported at a time).
2. Select the Leakers file by choosing Browse.
3. Make sure the Leakers box is X'd.
4. Select Import to begin importing the leaker data. When the import is complete, the data
will be output to the screen.
5. Next, select Process on the toolbar. This function places the leak counts into the Leak
Counts column within the Source table. Some of the rows may get highlighted in blue.
This means that the data does not match with the information in CALCS. When
processing is complete, a status box will appear saying either that the process was
successful or that the contractor supplied data could not be processed. Click OK, and a
reminder will appear saying to Process Totals now to calculate zeros.
6. If certain rows could not be processed, see “Common Errors That May Cause Data Not
To Be Processed” on how to resolve data that could not be processed. Correct the data
and repeat Step 5.
6.3.2 Totals and Zeroes
If you have not processed the Leakers file, do so before proceeding!
1. Select the Totals file by choosing Browse.
2. Make sure the Totals and Zeros box is X'd.
3. Select Import on the toolbar to begin importing the Totals data. This may take several
minutes to complete because CALCS is reading and inserting each row into the database.
When the import is complete, the data will be output to the screen.
4. Select Process on the toolbar. This function inserts the total counts in the appropriate row in
the Leak Counts tables in Sources. Next, it will calculate the zero leakers by subtracting the
number of leaking components from the number of total components. Some of the rows may
get highlighted in blue. This means that the data does not match with the information in
CALCS. When processing is complete, a status box will appear saying either that the process
was successful or that the contractor supplied data could not be processed. Click OK.
5. If certain rows could not be processed, see section on Resolving Unprocessed Data. Correct
the data and repeat Step 4.
6. Close out of this window and select Sources. Select an Equipment Leak emission Source and
proceed to the Leak Count tab. Check to see that the process worked.
7. Repeat all importing steps for the remaining estimation periods.
6.3.3 Calculating Emissions
ACM-CALCS–Manual
Page 113
After importing the Contractor Data, you are ready to calculate emissions. Go to the Calculate
window, and calculate emissions for the Equipment Leak Sources as you would for any other
Source.
If correlation equations are used to estimate emissions, the user must enter estimation dates that
correspond to the estimation periods used when setting up the emission Sources, and do a
calculation for each estimation period (i.e. 1/1/2007–1/31/2007). CALCS will prompt the user to
"Select the files for use in the correlation equation." Choose the Leakers file that corresponds to
the correct estimation period, and CALCS will read the actual leak rate values from the Leakers
file and input them into the correlation equation. This will take several minutes because CALCS
will have to import the file again. Repeat this process for each estimation period. When all the
emissions have been calculated once, you may select an estimation period that spans all the
estimation dates to sum up these emissions if you mark the box Use Existing Results before
selecting Run. For instance, if you chose to set up monthly estimation dates for the year 2007,
you may choose 1/1/2007–12/31/2007 in this window to Calculate the emissions for the entire
year. If no correlation equations were used to estimate emissions (only emission factors used),
you may choose 1/1/2007–12/31/2007 whether or not you had Calculated emissions once before.
This is possible because CALCS does not have to pull in any import files for emission factors.
(You may also Calculate multiple date ranges simultaneously for any other Source Type in
CALCS.)
You may display the results in several different report formats if you choose Options and the
desired report under General Reports or Process Unit Reports. Select Use Existing Results, and
then Run. The Source Detail report will give you the most detailed information, including a
listing of the Leak Counts. This report is good for QA/QC of the data. The Source and Stream
Summary report sums up emissions by Source and Stream. The General Description Summary
report totals all the fugitive emissions on one page.
6.3.4 Format of Contractor Data
The imported files must be in a specific format, and your contractor should be able to supply you
with the data in the correct format at minimal cost. Usually, the contractor charges a one-time fee
for the initial programming to get the data in this format, but should not charge any more to
continue supplying the data in this format.
First, decide how frequent you would like to obtain fugitive data. Some plants desire the ability
to quantify each month's emissions, and others only require quarterly emissions reports. Still
others may only need an annual report. Note that monthly emissions gives you the most
flexibility. You can easily sum the emissions for each year if needed. On the other hand, a yearly
report cannot be broken down by emissions occurring in each month. Consider this step carefully
before proceeding.
Next, ask the contractor to supply you with data. It must be ASCII (text) files in comma
delimited format with the specified character format for each estimation period. An example of
comma delimited format is: "01/01/2007","01/31/2007","01234","NSPS","ASPHALT". If you
choose monthly emissions, you will get 12 sets of files, one set for each month in a reporting
year (2 files per set).
ACM-CALCS–Manual
Page 114
For each estimation period, the contractor will need to supply you with two files: a Leakers file
and a Totals file. The Leakers file is a listing of all the leaking components and their ppm leak
rates during the estimation period. (Note that we are considering leaking components as any
component leaking above background zero, not the regulatory 10,000 ppm definition.) The totals
file is a listing of the total number of components by Stream in the plant during that estimation
period.
The information in each file should be the most recent available. For instance, if a certain Unit is
not monitored during the time period of interest, then information for that Unit should be
obtained from the most recent past data. If the past data indicates that a particular component
was screened at 1000 ppmv, then it should continue to be recorded in these monthly tables as
being screened at 1000 ppmv until it is monitored differently in the future. All components in the
plant should be accounted for in these tables each month, regardless of how many are monitored
each month.
The Unit and Stream Information has a primary and secondary priority to it. The Unit ID and
Stream ID should always be filled in. If the only data available is the Unit name or Stream name,
then this data should be placed in the Unit/Stream ID column with the Unit/Stream Name
column blank. If this is the case, the format restricts the number of characters to the specified
format.
The reason why the blank column exists in the Totals file is that the two files need to have the
same number of columns so that CALCS can import the files correctly. The contractor format
will read: "01/01/2007","01/31/2007","NSPS",,"ASPHALT" and so on. Note the 2 commas that
indicate a blank column.
6.3.5 Resolving Unprocessed Data
After you have imported contractor Equipment Leak data and have run the "Process" data step,
you may find that a number of records could not be processed. This is because something in
CALCS is not linking correctly with the contractor data. You may have left a necessary piece of
information out of a record, the contractor may have added Streams that you don't have input in
your records, and so on.
The rows that could not be processed are highlighted in blue on the "Import and Process" screen.
You may view these rows by scrolling down the file line by line. Note the first highlighted row.
Without closing this screen, click on the following items to determine what the problem may be.
(Do not close the import screen, or you will have to repeat the entire process of importing and
processing the data. You may have many windows open at one time, and an easy way to switch
between open windows is the select Window from the menu bar and the correct window to
view.)
6.3.6 Common Errors That May Prevent Processing
If you find that you only need to make a change to a few items, it may be quicker to manually
input the Leak Count. Do this by going to the Leak Count window in the Sources screen,
entering the Leak Count, and saving.
ACM-CALCS–Manual
Page 115
1. From the Import window, select Reference, Process Units. Check to see that the correct
Process Unit ID is entered. If not, add it from this screen.
2. From the Import window, select Reference, Component Types. Check to see that the
abbreviations used by the contractor correspond to the existing abbreviations in this
window. If the abbreviation does not exist, add it to this window.
3. Click on Sources on the toolbar. Check to see that the Stream has been added to the
correct emission Source record. If not, add the Stream and save. If you add a Stream in
emission Sources, check to see that the Leak Contractor Stream ID has been listed in
Unit/Streams.
4. Also in Sources, check to see that you have the correct estimation dates. If not, create a
record with the correct estimation dates and save.
5. Click on Unit/Streams on the toolbar. Check to see that the correct ID for the Stream is
listed in the Leak Contractor Stream ID column. If the contractor has a different Stream
ID, either:
(a) add another Stream with the same information except the new Stream ID (i.e. if
Stream is fuel gas, rename fuel gas-2), or
(b) change the Stream ID, as long as the contractor did not use the existing Stream ID for
any of the imported Streams.
If (a) is done, add this new Stream to the emission Source record.
If for some reason the contractor has monitored components or Streams that you do not need to
report or Calculate emissions from, then simply ignore this highlighted row. The data will not be
imported.
After troubleshooting is complete, you will need to reprocess the data from the Import window
by selecting Process. If rows are still incompatible, the rows will be highlighted in blue. Repeat
this troubleshooting procedure until all the errors are found. Remember, if you find that you only
need to make a change to a few items, it may be quicker to manually input the Leak Count. Do
this by going to the Leak Count tab in Sources, entering the Leak Count, and saving.

CHAPTER 7: NEW YORK STATE FEATURES
7.1
NY–Stream Properties and Composition
The CALCS module depends on Stream Properties information to determine emission rates of
the specific chemical constituents that make up a material. Each material may be defined in the
program by clicking on the Stream Properties icon on the main toolbar, as shown below.
A material composition is referred to as a Lab/Sample ID. In the standard version of the CALCS
module, a drop-down list of Lab/Sample ID.’s is displayed from which the user selects one item
to edit or delete. In the New York version, due to the large number of potential materials
(>200,000 items), users enter the Lab/Sample ID that they wish to view, change, or delete next to
the phrase Enter Lab/Sample ID. If the material was previously entered, it will be found and
displayed. Otherwise, the program will assume the material will be added to the list.
Compositions may be updated automatically by using a feature that links to the “MSDS”
database, shown below.
7.2 NY–Emission Calculations for Batch Processes
The Batch Calculation feature and related features, such as automatic updates from production
and materials databases, are custom features that were added to the CALCS module especially
for New York. Program functions related to creating Formulas and Profiles for continuous
Sources, calculating emissions, summing Secondary and Primary Sources, and other features, are
explained in the rest of the CALCS user’s manual.
Batch calculations require extensive “setup” data to be entered into the system to identify how
the batch processes operate. Once created, the Batch Source information may be updated with a
more streamlined set of information to Calculate emissions for future time periods. The Number
ACM-CALCS–Manual
Page 117
of Batches field – an important data element that drives significant portions of the emission
calculations – can be updated automatically from the PIMS database through a feature that is
explained in the next section. This section concentrates on manual data entry by engineers or
technicians who understand batch processes and are familiar with the type of information that
will be required by the system to Calculate emissions.
A Batch icon appears on the main screen of CALCS, as shown below, which may be used to
access all batch-related functions.
Using this set of features, users can simulate a multi-step batch process with charge, drain, and
clean out operations. Each set of batch emission calculations is associated with a product grade
being manufactured.
One reactor vessel can be in service for manufacturing multiple product grades. The emissions
from each batch are then extrapolated to an annual emission based on the number of batches
produced in a given year. The software estimates the potential to emit (PTE=total uncontrolled
emissions) for a given Source and the ERP (maximum uncontrolled emissions).
7.3 NY–Navigating Batch Calculation Screen Tabs
The user can enter any number of steps to simulate a manufacturing process. Each step can be
associated with heating, pressurization, and material charging activities. The grade explorer on
the left side of the screen keeps track of the various production batches being run. Each grade
ACM-CALCS–Manual
Page 118
(product) represents a batch from a production standpoint and it is associated with one or more
steps involved in the manufacturing process. The user specifies the operating parameters for each
step, for example the temperatures, pressures, etc. The user also chooses a flow condition which
points to a control device network configuration utilized for emissions abatement.
ACM-CALCS–Manual
Page 119
The second tab displays material input/output information. The user selects an input grade or raw
material from a predefined set of materials stored in the database. These materials and their
chemical compositions are user maintained. When a user selects an input grade, the
corresponding chemical composition is displayed under grade composition. The number of
pounds of each chemical fed to the reactor is calculated from the grade/material composition.
The bottom section of the Charge tab displays the material balance for the current step. The
emissions are calculated based on the moles of vapor displaced during the current step. The
volatility of various chemical species at the given temperature and pressure and the volume of
material charged affect the number of moles displaced. Heating, de-pressurization, and material
charging all lead to vapor displacement from the reactor. The vapor pressures of various
chemical species determine how much each will contribute to the total emissions resulting from
vapor displacement.
ACM-CALCS–Manual
Page 120
Chemicals charged into the vessel can participate in one or more reactions. The software
identifies the limiting reactant based on the quantities of the reactants present during a given step
and the reaction stoichiometry. The limiting reactant is the chemical species that will be
completely consumed during a given chemical reaction, and the reactor will still be left with
other reactants to spare. Hence, the reaction can only proceed when all of the limiting reactants
are available. The program also accounts for the percent completion of a reaction. The maximum
amount of limiting reactant that can participate in a given reaction will be dictated by the percent
completion of the reaction.
Each step can optionally be linked to a control device that is integral to the process.
This control device is not a regulatory abatement device but a process control device, such as a
condenser or a scrubber. The software performs a vapor liquid equilibrium calculation using the
Newton-Raphson computation method. This calculation provides the final emissions after
condensation/scrubbing. The resulting condensate can also be recycled to the system by selecting
the Total Reflux checkbox. The calculations yield percent control efficiency for each chemical.
This process results in generated emissions from a given step.
ACM-CALCS–Manual
Page 121
The Calculations tab displays vapor pressures, vapor fractions, moles of liquid and percent
control efficiency achieved from the process control step. If there is no process control, then the
potential and calculated emissions are the same.
During the calculation process, if any missing parameters, such as molecular weights, densities,
Antoine coefficients, etc. are detected by the program, it notifies the user through a list of QA
codes. The QA codes will also trap value overruns – for instance, vapor fractions greater than
1.0. If a user inadvertently inputs more material than the reactor can hold, the system assigns QA
code #12. Such user notifications can be very helpful to identify problems and ensure correct
emission calculations.
ACM-CALCS–Manual
Page 122
7.4
NY–“Rolling Sum” of Emissions
EI module data is used to produce a report that shows the Rolling Sum of emissions from Batch
Sources. This feature is run from the Batch Sources screen in the CALCS module, as shown
below. When run for a specific Source, this feature searches all records in the PIMS (i.e.,
Production database) to obtain a total number of Batches produced in each month during the
prior twelve months. Emissions data in EI is used to correlate the emission amounts with the
number of batches, so it is important for users to have calculated emissions and to have used the
data PIPELINE to update EI for any time period in which a Rolling Sum report is produced.
ACM-CALCS–Manual
Page 123
7.5
NY–PIPELINE
The data PIPELINE is accessed by clicking on the PIPELINE icon in the COMPASS folder. As
shown below, the main toolbar has two reference lists to assist the user to synchronize data
between CALCS and EI modules for the export of emissions. They are Equip, which displays
equipment relationships, and Contam, which displays a list of chemicals with the EI-assigned
contaminant code and CALCS-assigned CAS Number. In order for chemical-specific emissions
to transfer from CALCS to EI, it is necessary for the correct CALCS-assigned CAS Number to
be correlated with the related EI Contaminant Code.
The Batch Pipe icon provides a list screen to select batch Sources for transferring emissions from
CALCS to EI, as shown below. The Emissions icon provides a list screen to select non-batch
Sources for transferring emissions from CALCS to EI.

This is a safeguard. When
you click List while in the
Quick Edit screen, you
'retrieve' data. If you edit
and save you 'update' the
database. CALCS looks for
key data of a Source to
make sure the changes are
saved to the original Source
with the original Stream,
etc. If another user or even
the same user changes any
of the key data (probably
from another screen)
between List (retrieve) and
Save (update), the original
key data is lost. CALCS
thus won't be able to save
the data.
The solution is to click List again
to retrieve the current Source key
data and edit again.
Unfortunately, previous changes
are lost. The single user
preventive measure is to Quick
Edit without opening any other
screens until saved. The multiple
user mitigative measure is to save
often so as to minimize the

Possible Cause
The difference between

setting range. A term the
Formula is “(max vp – min
vp) – setting range”.
Negative number in a field.
Formula screen has a
Compound entered that is
not in the related Stream

Source screen has an
erroneous Tank Avg Liq
Surf Temp. It should be in
degrees R (460+F).
Manually entered emissions
for VOC are applied to a
Stream Composition
without VOC specifically
listed.
The Leak Counts tab does
not have that Stream.
The Profile referenced by
the Source lists a
Compound not in Stream
Properties, or its
concentration is blank.
Resolution
Set the breather pressure and
vacuum settings so that the range
equals the vp range. Any larger
setting is irrelevant, because the
vp never overcomes the vent
settings.
Check all fields for negatives.
Trace back from Formula screen,
though Profile to Source to find
Stream. Add Compound and/or
concentration in Stream

Correct the temperature.
List VOC in Stream Composition

VOC is not at the top

Zero emissions for a
Stream after running
‘Calculate’.
Possible Cause
Too many ‘zero’ emission
records in database.
Too many users on Citrix
server.
Daily vapor pressure range
< breather vent range.
AP42 says if daily vapor
pressure range > breather
vent range, the difference is
used to calculate breathing
loss. If <, breathing loss is
zero. CALCS formulas
have no if statement, thus
formula always subtracts,
sometimes calculating a
negative breathing loss.
The erroneous negative plus
the working loss yields a
low total.
Reports will put ‘Multiple’
contaminants at the top
alphabetically. Alkanes-u
and similar contaminants
are listed as ‘Multiple’ in
‘Compounds’ screen.
Formula variable is
referring to a blank field.
Make the daily max and min
vapor pressure equal to the
average. Also, make the breather
setting range zero. A fix for this
problem is in process.
Compound in Profile, but
not in Stream Prop.
Change Compounds to ‘Single’ in
Compounds screen to put them at

disadvantage is that they cannot
then be further speciated in a

•
In PIPELINE, click Emissions button
o Pick year, Facility, and FIN, filtered by Unit and Source Type only if desired.
ACM-CALCS–Manual
Page 140
o Click List button
If FIN is not on pick list, click Err Report button for clues, ‘Select
Reports’ of all 3 kinds, and do the following as needed:
• Run CALCS Calculate as usual. Source will not appear on
PIPELINE–Emissions pick list if Calculate hasn’t been run.
• If the Source has Secondary Sources, sum them:
o In CALCS, click Inventory button
o Highlight the Primary and all Secondary Sources together
o Click Retrieve button
o Click Data and Sum Emissions
o Highlight the desired Primary only
o Click Sum & Delete (normally)
• Reconcile equipment relationships, if needed
o In PIPELINE, click Equipment button
o Click Insert button
o Pick FIN, EPN, CIN (pick ‘-‘ for the first blank CIN), or
add if needed:
If CIN not in pick list, right click blank, choose
‘add’, and complete add screen, then ‘OK’
Go back and pick FIN, EPN, CIN, etc.
o Click Save button
• Reconcile CAS#, if needed
o Look in CALCS Compounds to see the listed CAS
number(s) for the FIN’s contaminants.
o In PIPELINE, click Contam button
o Search for same Contam(s)
o If CAS# shown in EI/PIPELINE needs to be changed, type
it in exactly as it is in CALCS. If the CAS# in CALCS
needs to be changed do the following:
Write down the ID of all Stream Prop screens with
that Compound and write the concentrations.
Write down all information similarly for Formulas
and Profiles with that Compound.
Correct the CAS# in Compounds and save.
That Compound will now be missing from all
associated Stream Prop, Formula and Profile
screens.
Insert it correctly in Compounds screen.
Add that Compound and concentration back into all
Stream Prop, Formula and Profile screens and save.
If a non-unique error pops-up, close and reopen the
screen and retry.
Rerun Calculate for the FINs that have been
previously Calculated with that Compound by first
finding affected FINs.

• Alternatively, CALCS Unit/Streams can be
sorted by Stream Properties (written down
above) to find Unit Streams involved, and
then Equipment Relationships show the
Sources that are linked to those UnitStreams.
Rerun Inventory and the Sum and Delete selection
above for all affected Primary-Secondary families.
It may be advisable to first delete all emissions
existing in the Primary Source.
Rerun PIPELINE for those FINs having the
Compound.
In EI, delete the erroneous Compound if still there:
• Click the first FIN with the erroneous
Compound to see the emissions.
• Double click the erroneous Compound line
where emissions are shown.
• “Add Emissions?”, “No”
• Double click the erroneous Compound in the
detail screen to open the record.
• Click Delete, (Are you sure?) Yes.
• Return to the main screen.
• Refresh or choose another FIN and go back
to the subject FIN to see if the deletion
worked.
• Repeat for all FINs with the erroneous
Compound.
Click Emissions and List if not already done in PIPELINE.
If error message says, “No emissions capable of export for
[Facility/account #] for [YYYY]”, check in EI module to see if Source is
labeled ‘idle’ for current year. If so, change to ‘active’ and try ‘List’ again
in PIPELINE.
Check all 3 ‘Err Reports’ or CALCS ‘Estimate Emissions’ to make sure all
expected contaminants are found when clicking PIPELINE-Emissions-List.
If there are unwanted contaminants with zero emissions, in CALCS, click
Inventory button, find Source, ‘Retrieve’, delete all lines with zero emissions and
save. Then ‘List’ again in PIPELINE. The other option is to pipe them to EI and
delete them there by selecting the Source and double-clicking one of the
contaminants. The entire contaminant list will appear. Select the row for
deletion, and making sure the green arrow at left is pointing to the correct row,
click delete below. Repeat as needed and save.
