CBI Status-Survey

Documents Steam Electric Survey data excluded from use in assessing treatment in place 

because the data do not represent treatment of flue gas desulfurization wastewater using 

chemical precipitation.

Additional information regarding the query performed to extract pertinant information from 

the Steam Electric Survey Database.

CBI status of selected responses to the Steam Electric Survey

Documents Steam Electric Survey data excluded from use in assessing treatment in place 

because the data are too incomplete for use.

This Excel workbook documents EPA's assessment of FGD wastewater treatment in place at steam electric plants.

Documents plant-specific assessments of FGD wastewater treatment in place and EPA's 

determinations regarding costs/loads credits assigned based on an evaluation of these data. 

These determinations where then used to populate the "Treatment-In-Place Input Table" 

used in the Steam Electric Costs and Loads Model (described in Section 4.4.2 of DCN 

SE01957).

Documents Steam Electric Survey data excluded from use in assessing treatment in place 

because the data do not represent treatment of flue gas desulfurization wastewater 

generated by wet FGD systems.

Documents information provided in response to the Steam Electric Survey regarding FGD 

wastewater treatment chemical additions. Documents calculations performed using these 

data.

Notes

Contains data from the following survey questions:

A1-1 Plant Name

B7-4 FGD purge wastewater treatment

D5-3 WWT flow rates

D5-6 Sulfide add'n capability

D5-7 Sulfide add'n performed

D5-13 Chemical add'n by WWTU

Purpose: Lists flow rates, sulfide add'n information, and chemical add'ns for all 

WWT systems at plants that have CP systems (as marked in B7-4). Note: while 

only plants with CP systems are included, some of these plants have multiple 

treatment systems, including non-CP systems. All of the systems (including nonCP systems) are included.
