POND/IMPOUNDMENT SYSTEMS AND OTHER WASTEWATER
TREATMENT OPERATIONS
INSTRUCTIONS
Part D requests information about all ponds/impoundments used (or planned to be used
or under construction/installation by December 31, 2020) for the storage, treatment,
and/or disposal of process wastewater, residues, or by-products (or sludges or water
streams containing the residues or by-products) from the combustion of coal, petroleum
coke, or oil, including but not limited to fly ash, bottom ash, boiler slag, or flue gas
emission control residues. Additionally, Part D requests information about wastewater
treatment systems, other than pond/impoundment systems, for the treatment of
wastewaters from ash handling or FGD operations that are located at the plant or are
planned to be located at the plant. Complete Part D if you operate one or more systems,
or if you are currently constructing/installing, or planning to construct/install one or more
systems by December 31, 2020.
Refer to the following definitions throughout Part D.
A "pond/impoundment" is defined as a natural topographic depression, man-made
excavation, or diked area formed from earthen materials or man-made materials or a
combination of them, which is designed to hold an accumulation of liquid process
wastes or process wastes containing free liquids, and which is not an injection well.
Examples of ponds/impoundments include holding, storage, settling, and aeration pits,
ponds, and lagoons. It does not include building sumps and outdoor collection/transfer
concrete basins.
A “pond/impoundment system ” is defined as a system consisting of one or more
ponds/impoundments.
A “wastewater treatment unit ” is defined as a unit operation used to remove pollutants
from process wastewater. Wastewater treatment units include, but are not limited to:
ponds/impoundments, chemical precipitation, pH adjustment, clarification, biological
reactor, thickeners, filters, and constructed wetlands.
A “wastewater treatment system ” is defined as a combination of one or more
“wastewater treatment units”, other than ponds/impoundments, designed to achieve
wastewater treatment.
NOTE: If a pond/impoundment unit (as defined in Section 4.1) is part of a broader
“wastewater treatment system” containing non-pond units (e.g., a
pond/impoundment unit in a biological wastewater treatment system), it is not
considered part of a pond/impoundment system.

Steam Electric Questionnaire
Part D. Instructions
Throughout Part D, information is requested for pond/impoundment and wastewater
treatment units and systems that are under construction/installation, or planned to be
under construction/installation by December 31, 2020. Provide design information, or
best engineering estimates as necessary, for these planned systems/units. Additionally,
indicate “NA” if the information requested is not applicable for planned systems/units
(e.g., a question that requests flow rate data for year 2009).
As you are completing the electronic form, note the following: When you enter your plant
name and plant ID on the Part D Table of Contents tab, all name and ID fields
throughout Part D will automatically populate. Refer to the overall questionnaire
instructions, the glossary, and the acronym list for assistance with completing Part D.
Please provide all free response answers in the highlighted yellow areas. Throughout
Part D, you may need to make copies of certain sections/questions. Instructions are
provided throughout Part D regarding making copies. Note that pond/impoundment
system (and unit) and wastewater treatment system ID's 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 pond/impoundment or
wastewater treatment system.
Use the Part D Comments tab to do the following: provide additional information as
requested in certain questions within Part D; 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.

List these wastewater treatment systems in Table D-2. For each wastewater treatment system, EPA assigned a number (e.g., WWT-1, WWT-2) in Table D-2, which will
be used throughout the remainder of the survey. In the “Plant Designation” column, provide the plant’s name for each wastewater treatment system. As an example, if a
plant operates a chemical precipitation FGD wastewater treatment system that discharges to an ash pond/impoundment system (as shown in EPA example diagrams
EPA_D-1 and EPA_D-2 located at the bottom of Part D Section 3.1) the FGD wastewater treatment system should be identified in Table D-2 (e.g., as WWT-1) and the
ash pond/impoundment system should have been previously identified in Table D-1 (e.g., as POND-1).
Note that "Approximate Length of Piping from FGD Scrubber System" refers to the length of piping from the FGD solids separation overflow storage tank (or FGD
scrubber absorber if no FGD solids separation) to the beginning of the FGD wastewater treatment system. "Approximate Length of Piping to Subsequent Treatment or
Discharge" refers to the length of piping from the end of the FGD wastewater treatment system to either the beginning of the subsequent treatment system or the
wastewater discharge point,
as appropriate.

Block Diagram Checklist
Mark the boxes below to verify that you have completed each checklist item…
Include the block diagram number, plant name, plant ID, and pond/impoundment system ID or wastewater treatment system ID
on the diagram.
Include each pond/impoundment or wastewater treatment unit operation. Show all influent and effluent streams from the units
and label all influent and effluent streams from the pond/impoundment system or wastewater treatment system using the code
tables on the "Code Tables" tab provided at the end of this workbook. Note that the "Code Tables" tab provides codes for
wastewater treatment units that are operated in series and/or in parallel (e.g., in EPA_D-1, Chemical Precipitation Reaction
Tank 1-1 and Chemical Precipitation Reaction Tank 2-1 are in series). Effluent streams may include process wastewater and
sludges .
If applicable, use EPA-assigned numbers from Part A or B (e.g., FGD-1) to label process operations . If a process operation
does not have an EPA-assigned number (e.g., boiler, air preheater), use the plant-designated name for the process operation.
When sources or destinations are not shown on the diagram (i.e., the stream is entering from a location not shown on the
diagram), describe the source or destination and add the block diagram number, when appropriate, where the stream's previous
location can be seen. Use codes from the code tables on the "Code Tables" tab provided at the end of this workbook.
Indicate where chemical addition occurs (i.e., into or between which wastewater treatment units). For pond/impoundment
wastewater treatment units, indicate and note on the diagram where within or near the pond/impoundment the chemical is
added (e.g., within the pond/impoundment near the process wastewater influent point, within the pond/impoundment near the
effluent, in the effluent/discharge canal). The chemicals indicated should correspond to the chemicals listed in Table D-7 and
Table D-13.
Identify the final, general destination of the treated process wastewater and waste streams (e.g., treated process wastewater
effluent to POTW or surface waters; solid wastes to on- or off-site destinations). Use codes from code tables on the "Code
Tables" tab provided at the end of this workbook, when applicable.
Indicate, as appropriate, where treated process wastewater is reused or recycled within the plant (e.g., reuse of settling
pond/impoundment water as fly ash sluice).
Include the average annual (2009) flow rates for influent and effluent streams from the wastewater treatment system on the
diagram (in gpm or gpd). For planned pond/impoundment systems and wastewater treatment systems, provide the design flow
rates for the system. Note that these should be the same flow rates that are entered into Tables D-3 and D-4 in Questions D3-2
and D3-3. If the actual number of days of operation for 2009 is not known, the total annual flow may be divided by 365 days and
a comment added to the Comments page. If the process 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.
Include NPDES permit outfall numbers, if applicable.
