## Development of FGD Costs and Loads Input Table - **Current FGD Systems**

This Excel file contains the following worksheets:

Leachate and FGD TIPList of 41 plants identified as having some level of treatment in place for their FGD wastewater. EPA compared the planned wastewater flow (FGD wastewater plus landfill leachate) to the design flow rate of the wastewater treatment system as provided in Part D Section 5 of the survey. If the combined FGD wastewater and leachate flow was less than the design flow of the treatment system, EPA determined that the existing TIP could handle both wastewaters. If the flow was greater than the design flow, or within 10%, EPA assumed that an entirely new treatment system would need to be constructed to handle only the landfill leachate. These plants costed for a separate treatment system to handle landfill leachate are highlighted in yellow. This Excel workbook documents the analyses conducted by EPA to determine how to handle leachate discharged by plants that are currently treating FGD wastewater.

EPA's costing methodology assumes that FGD wastewater and landfill leachate will be handled and treated by the same wastewater treatment system. For plants currently treating the FGD wastewater EPA evaluated whether the current treatment in place equipment could handle the additional wastewater flow by comparing the new flow (FGD wastewater + landfill leachate) to the design flow of the wastewater treatment system reported in the Steam Electric Survey.List of 41 plants identified as having some level of treatment in place for their FGD wastewater.
