PART B. FLUE GAS DESULFURIZATION (FGD) SYSTEMS
INSTRUCTIONS
Part B requests information about flue gas desulfurization (FGD) systems that are
located at the plant or are planned to be located at the plant. Complete Part B if you
operate one or more FGD systems, or if you are currently constructing/installing or
planning to construct/install one or more FGD systems by December 31, 2020.
Throughout Part B, information is requested on FGD systems that are under
construction/installation or planned to be constructed/installed by December 31, 2020.
Provide design information, or best engineering estimates as necessary, for these
planned systems.
As you are completing the electronic form, note the following: When you enter your plant
name and plant ID on the Part B Table of Contents tab, all name and ID fields
throughout Part B will automatically populate. Refer to the overall questionnaire
instructions, the glossary, and the acronym list for assistance with completing Part B.
Please provide all free response answers in the highlighted yellow areas. Throughout
Part B, you may need to make copies of certain sections/questions for multiple FGD
systems. Instructions are provided throughout Part B regarding making copies. Note
that system ID fields must be populated on the copied tab or section, located in the
upper right corner under "Plant ID" and "Plant Name", in order to correlate the requested
information with the correct system.
Use the Part B Comments tab to do the following: provide additional information as
requested in certain questions within Part B; indicate atypical data (e.g., if 2009
information is not representative of normal operations); and note methods used to make
best engineering estimates in the event that exact data are not available.

Section Title: 1. General FGD System Information
Instructions: Part B requests information about flue gas desulfurization (FGD) systems that are located at the plant or are planned to be located at the plant that are used to service fossil-fueled electric
generating units. See Part A Section 8 for unit classifications. Complete Part B if you operate one or more FGD systems , or if you are currently constructing/installing or planning to
construct/install one or more FGD systems by December 31, 2020, to service fossil-fueled electric generating units.

B1-2. Complete Table B-1 for each FGD system that the plant operates that services fossil-fueled electric generating units, or is currently constructing/installing or planning to construct/install to
service fossil-fueled electric generating units by December 31, 2020. Assign an FGD system ID to each FGD system using the drop down menu provided. Assign the FGD systems
sequentially using the numbered IDs (e.g., FGD-1, FGD-2) for the systems currently operating. Assign the FGD systems sequentially using the lettered IDs (e.g., FGD-A, FGD-B) for the
systems that are planned to operate. Enter the date the system initially began operation or is planned to begin operation. Identify each steam electric unit (currently operating or planned units)
that is serviced by each FGD system using the codes EPA assigned to steam electric units in Table A-8 and/or Table A-9. Identify the type of oxidation performed in the FGD system for all
wet FGD systems (Note: mark "Not Applicable" for dry FGD systems). Also provide the design or actual sulfur dioxide removal efficiency for each FGD system.
Wet FGD systems capture sulfur dioxide from the flue gas using a wet slurry that generates a process wastewater that exits the scrubber absorber, shown as FGD slurry blowdown in Figure B1 for recirculation scrubbers, or as FGD slurry discharge in Figure B-2 for single pass scrubbers. Indicate for each FGD system if FGD slurry blowdown (or FGD slurry discharge) is generated.
Use the drop down boxes to identify the type of FGD system and to specify the type(s) of sorbents used in the system. If a sorbent used is not provided in the drop down, identify "other" and
provide the type(s) of sorbent in the yellow highlighted box to the right.

For example, a plant may operate a gypsum stacking operation using a pond/impoundment, and some amount of FGD solids that are transferred
to the pond/impoundment are dewatered and sold for use in wallboard manufacturing. In this case, the amount of FGD solids sold for wallboard
manufacturing should be identified in BOTH the "Sent to Pond/Impoundment reported in Table A-4: Stored temporarily" category AND the
"Marketed and Sold" category. In this same example, all the FGD solids that are transferred to the pond/impoundment and either left settling at the
bottom of the pond/impoundment or used in increase the banks of the pond/impoundment should be identified as "Sent to Pond/Impoundment
