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.

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 begin constructing one or more FGD systems to service fossil-fueled electric generating units.

CBI?

B1-1.

Does the plant operate one or more flue gas desulfurization (FGD) systems that service fossil-fueled steam electric generating units, or is the plant currently constructing/installing or planning to construct/install one or more FGD systems to service fossil-fueled steam electric generating units by December 31, 2020?

(Continue)

CBI?

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 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 B-1 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.

8. Dry FGD System Information

Instructions:

Throughout this section, you will be required to provide information for each dry FGD system that the plant operates, reported in Table B-1. This section does not need to be completed for planned systems. Please provide all free response answers in the highlighted yellow areas.

Make copies of Section 8 and Section 8 tables for each dry FGD system previously defined in Table B-1 using the Copy Section 8 and Section 8 Tables button below. Please note that you will create two new tabs for these sections. You may delete unneeded tabs, if accidently created. Enter the FGD system ID in the space provided above (use FGD system IDs assigned in Table B-1).

Section Title:

8. FGD Solids Disposition and Marketing for Dry FGD Systems

Instructions:

Throughout this section, you will be required to provide information on FGD solids disposition for all dry FGD systems that the plant operates reported in Table B-1. This section does not need to be completed for planned systems. Please provide all free response answers in the highlighted yellow areas.

CBI?

B8-12.

In Table B-10, indicate the ultimate destination of FGD solids from the FGD system and provide the tonnage for each type of storage/handling technique for calendar years 2005, 2007, and 2009. If the FGD solids are stored in a landfill or pond/impoundment, provide the amount of FGD solids stored permanently and/or temporarily. For example, a plant may operate a gypsum landfill, and some amount of FGD solids that are transferred to the landfill may later be removed from the landfill 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 "Landfills reported in Table A-6: Stored temporarily" category AND the "Marketed and Sold" category. In this same example, all the FGD solids that are transferred to the landfill and left in the landfill should be identified as "Landfills reported in Table A-6: Stored permanently."

Complete Table B-11 if the plant markets, sells, and/or gives away the FGD solids from this FGD system. For each destination, provide the tons of FGD solids for which the FGD solids are marketed, sold, and/or given away. Also provide the gross revenue generated from marketing/selling the FGD solids for each destination.
