PART A. STEAM ELECTRIC POWER PLANT OPERATIONS

Use the Comments tab at the end of Part A to do the following: provide additional 

information as requested in certain questions within Part A; 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

Complete Part A of the questionnaire for your plant. As you are completing the 

electronic form, note the following: When you enter your plant name and plant ID on the 

Part A Table of Contents tab, all name and ID fields throughout Part A will automatically 

populate. Refer to the overall questionnaire instructions, the glossary, and the acronym 

list for assistance with completing Part A. 

Please provide all free response answers in the highlighted yellow areas. Throughout 

Part A, you may need to make copies of certain sections/questions. Instructions are 

provided throughout Part A regarding making copies. Note that outfall number or steam 

electric generating unit ID 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 outfall or steam electric generating unit.

Where the questionnaire indicates to provide an attachment, an electronic format (e.g., 

PDF) is preferred; however, hardcopies are also acceptable.

Throughout Section 3 (Questions A3-1 to A3-3), provide information for all ponds/impoundments the plant has or is currently constructing/installing or planning to construct/install by December 

31, 2020.

Does the plant have or is the plant currently constructing/installing or planning to construct/install by December 31, 2020 any ponds/impoundments used for the storage, treatment, and/or 

disposal of process wastewater, residues , or by-products (including sludge or water streams containing residues or by-products)?

In Table A-4 below list all pond/impoundment units located at the plant, or pond/impoundments the plant is currently constructing/installing or planning to construct/install by December 31, 2020, 

including those located on non-adjoining property, used for storage, treatment, and/or disposal of process wastewater, residues, or by-products (including sludge or water streams containing 

residues or by-products). For each pond/impoundment unit, EPA assigned an ID number (e.g., SPD-1, SPD-2) in Table A-4, which will be used throughout the remainder of the survey. In the 

“Plant Designation” column, provide the plant’s name for each pond/impoundment unit. 

Additionally, provide the latitude and longitude at the pond outlet (see glossary), the closest distance from the pond/impoundment unit to the nearest surface water, the year the 

pond/impoundment unit was brought online (or is planned to be brought online), and indicate whether the pond/impoundment is lined or unlined and whether leachate (see glossary) is collected 

from the pond/impoundment (e.g., the pond/impoundment has a leachate collection system or other means for collecting leaks or seepage, etc.). Note: If the pond/impoundment does not have a 

pond outlet, provide the latitude and longitude corresponding to the emergency outlet for the pond/impoundment.

Note: This includes ponds/impoundments located on non-adjoining property that are under the operational control of the plant.

Review:

Identify the final destination of the treated wastewater and process wastewater (e.g., treated 

wastewater effluent to POTW or surface waters; solid wastes to on- or off-site destinations). Use 

codes provided in the Codes Table tab.

Indicate, as appropriate, where treated wastewater is reused or recycled within the plant (e.g., 

reuse of settling pond/impoundment water as fly ash sluice).

Identify all outfall locations. Include NPDES permit outfall numbers, if applicable.

Provide the typical flow rates for all streams on the diagram (in gpm or gpd). If the wastewater 

stream is intermittent, provide amount and frequency; for example “100 gal, twice/day, 100 dpy” 

or “1000 gpm, 4 hpd, 365 dpy”. For sludges, provide amount in tpd.

Identify all wastewater treatment systems used to treat the process wastewaters generated by 

the steam electric generating units. Represent the wastewater treatment systems as a block or 

other shape. Use EPA-assigned numbers from other parts of the questionnaire if applicable. If 

the wastewater treatment system does not have an EPA-assigned number, use the plantdesignated name for the wastewater treatment system.

If you believe that the diagram should be treated as confidential, stamp it "Confidential" or write 

"Confidential" or "CBI" across the top. If any diagram is not marked "Confidential", it will be 

considered nonconfidential under 40 CFR Part 2, Subpart B.

If any of the statements above were not checked, revise the block diagram(s) and ensure all
