PART D. POND/IMPOUNDMENT SYSTEMS AND OTHER WASTEWATER

TREATMENT OPERATIONS

INSTRUCTIONS

Part D requests information about all ponds/impoundmen ts 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-prod ucts (or sludges or water

streams containing the residues or by-products) from the co mbustion of coal , petroleum

coke , or oil , including but not limited to fly ash, bottom ash, bo iler slag, or flue gas

emission control residues. Additionally, Part D requests information about wastewater

treatment systems, other than pond/impoundment systems, f or the treatment of

wastewaters from ash handling or FGD operations that ar e 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 plan ning 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 materia ls or man-made materials or a

combination of them, which is designed to hold an accumul ation of liquid process

wastes or process wastes containing free liquids, and which i s not an injection well.

A “ pond/impoundment system ” is defined as a system consisting of one or more

ponds/impoundments.

A “ wastewater treatment system ” is defined as a combination of one or more

“wastewater treatment units”, other than ponds/impound ments, designed to achieve

wastewater treatment. A “ wastewater treatment unit ” is defined as a unit operation used to remove pollut ants

from process wastewater. Wastewater treatment units includ e, but are not limited to:

ponds/impoundments, chemical precipitation, pH adjustment , clarification, biological

reactor, thickeners, filters, and constructed wetlands.

NOTE: If a pond/impoundment unit (as defined in Sec tion 4.1) is part of a broader

“wastewater treatment system” containing non-pond uni ts (e.g., a

pond/impoundment unit in a biological wastewater tr eatment system), it is not

considered part of a pond/impoundment system.

# Steam Electric Questionnaire Part D. Instructions



# Please provide all free response answers in the highligh ted yellow areas. Throughout

Part D, you may need to make copies of certain sections/qu estions. Instructions are

provided throughout Part D regarding making copies. No te that pond/impoundment

system (and unit) and wastewater treatment system ID's mu st 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 informatio n with the pond/impoundment or

wastewater treatment system.

Use the Part D Comments tab to do the following: prov ide additional information as

requested in certain questions within Part D; indicate a typical data (e.g., if 2009

information is not representative of normal operation s); and note methods used to make

best engineering estimates in the event that exact data are not available. Throughout Part D, information is requested for pond/ impoundment and wastewater

treatment units and systems that are under construction/in stallation, or planned to be

under construction/installation by December 31, 2020. Pr ovide design information, or

best engineering estimates as necessary, for these planned systems/units. Additionally,

indicate “NA” if the information requested is not appl icable for planned systems/units

(e.g., a question that requests flow rate data for yea r 2009).

As you are completing the electronic form, note the fol lowing: When you enter your plant

name and plant ID on the Part D Table of Contents ta b, all name and ID fields

throughout Part D will automatically populate. Refer to the overall questionnaire

instructions, the glossary, and the acronym list for assistan ce with completing Part D.
