# Background:

**Data Element Dictionary:**

Database Table Name:Table name in the database that corresponds to the information in a specific set of information. Description: General description of the type of data contained within the database table.

Database Table Name:Table name in the database that corresponds to the information in a specific set of information.

Database Field Name: Field Type Text: Specified data type of the field name (e.g., text, numeric, memo). Field Description: Description of the field name. Field name within a database table that corresponds to a specific data element in the loadings model. Field names can be repeated for the same type of information being entered (i.e., Plant_ID). The primary

purpose of the FGD Settling Pond Concentrations Loadings Model (DCN SE02902) is to calculate the average effluent concentration from FGD settling ponds. This average concentration is then used as part of the FGD Wastewater Loadings Model (DCN SE02900) to calculate plant-specific pollutant loadings.

**Tables:**Provides a listing of all tables found within the FGD Settling Pond Concentrations Loadings Model along with a short description of the type of data contained within the table.

**Field Names:**Provides a list of all individual data fields found within the FGD Settling Pond Concentrations Loadings Model. The fields are organized by

table name. **Flue Gas Desulfurization (FGD) Settling Pond Concentration Loadings Model Data Element Dictionary - Summary 4/19/2013** 

The Incremental Costs and Pollutant Removals for the Proposed Effluent Guidelines and Standards for the Steam Electric Power Generating Point Source Category (DCN SE01964) provides a detailed description of the calculations used to estimate the average effluent concentrations from FGD settling ponds. These calculations are executed in the queries contained within the database. The database also includes a listing of the specific sampling data used in the analysis.

This MS Excel file is the data element dictionary that provides a description of the data elements contained within the FGD Settling Pond Concentrations Loadings Model. The elements of the dictionary include:
