Notes 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.

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 sy stems. All of the systems (including nonCP systems) are included.
