CHAPTER 3: EMISSION INVENTORY

There are twenty-two major sections in the EI Questionnaire, ranging from general information

about the plant to specific information about emission points and production materials. These

twenty-two sections are like a 22-drawer filing cabinet: Inside each drawer are file folders that

are labeled with a proper key identification number. For example, Sources are labeled by Source

ID numbers (also called "FIN" in Texas only), while emission points are labeled by Emission

Point numbers ("EPN"). Each file folder is called a record in data processing terminology; it is

the same as a row in a spreadsheet. In a record, there are specific items of information. For

example, each record in the Emission Points data table contains more than twenty-five items of

information. These items, or fields, contain such information as the height and diameter of the

emission point to the emission point name. In a relational database such as EI, every record

within a file contains the same number and types of fields.

In a file drawer, it is necessary to decide in advance how the file folders will be accessed, for

example, alphabetically, sequentially, etc. However, relational databases can dynamically sort

and re-sort records to meet your exact specifications. Another advantage is the ability to link the

contents of one file drawer with one or more drawers that have common fields. For example, the

drawer marked Facilities can be linked to the drawer marked Activities and Materials because

the FIN is common to both files.

EI is designed to furnish high-speed access to descriptive information about plant equipment and

processes. Not all companies are required to report air emission inventory data to regulatory

agencies on an annual basis, so the frequency of update will vary from user to user. PDC Corp

can provide interface software to link the EI module to emission calculations software. The

interface is included in the companion software module: COMPASS-Calcs.

The Account information window consists mainly of names and address information. The

Account encompasses a physical plant from which reported emissions are identified.

Following are the data elements in the Account information that are reported to the agency.

Account Information is located under File menu. Other data elements are also included for the

user's convenience in storing additional Account information. This information may be used by

other modules, such as the IntelliRegs, for generating a Title V Operating Permit application

form:

1. Account Name (Mandatory).

The company or owner responsible for emissions associated with the specific

plant/operating site.

2. Agency Acct No (Mandatory).

The account's identification number, assigned by the TCEQ, consists of seven characters:

two letters followed by four digits followed by a letter.

3. Organization Name (Mandatory).

The organization responsible for emissions associated with the specific plant/operating

site.
