PART B. FLUE GAS DESULFURIZATION (FGD) SYSTEMS

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.

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. 

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. 

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.

The following information should be provided for each data point:

 Name of analyte and CAS Number;

 Analytical method used;

 Sample-specific detection limit for the method used;

 Sample-specific nominal quantitation limit stipulated for the method used; Date the sample was collected; Location where the sample was collected (e.g., purge tank which collects secondary hydroclone overflow) Whether the sample was collected as a grab or as a composite (and note the compositing period used) Description of any qualifiers for the measurement; For metals, whether the sample was analyzed as total recoverable or dissolved

 Flow rate (only if flow rate data were recorded at the sampling point during the sampling period)

 Identification of FGD system(s) and steam electric generating unit(s) that the sample represents (report FG System IDs and associated steam electric generating units from Table B-1); and

Note: If you operate multiple FGD solids separation processes (e.g., two sets of hydroclones), only provide mthe last solid separation process. If necessary, you may provide additional information regarding the sample c

analytical methods in the Comments section (e.g., sample collection followed EPA Method 1669 protocols, dy
