PART D.	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.
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.
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.

		Part:	D
		Section Title:	3.1. Wastewater Treatment Diagram
		Instructions:	Complete Section 3.1 (Question D3-1) for each pond/impoundment system or wastewater treatment system identified in Table D-1 and Table D-2, including planned systems, systems under construction/installation, or planned to be under construction/installation by December 31, 2020. Enter the pond/impoundment system ID or wastewater treatment system ID in the yellow highlighted space provided above (use the pond/impoundment system ID or wastewater treatment system ID assigned in Table D-1 and Table D-2). Make a copy of Section 3.1 for each pond/impoundment system or wastewater treatment system identified in Table D-1 and Table D-2 using the "Copy Section 3.1" button below.
			Attach a block diagram that shows the pond/impoundment system or wastewater treatment system operations, the process wastewaters that currently enter or are planned to enter the pond/impoundment system or wastewater treatment system, and the ultimate destinations of the pond/impoundment system or wastewater treatment system effluent(s). Specific instructions for the diagram are provided in the checklist below. The diagram should have a similar level of detail as EPA’s example diagrams, EPA_D-1 and EPA_D-2. NOTE: You may use an existing diagram, such as a water balance diagram included in the plant’s NPDES Form 2C, and mark the additional required information on the diagram by hand. Provide as many diagrams as necessary to convey the information requested in the checklist below. Number each block diagram in the upper right corner; the first block diagram should be numbered D-1, the second D-2, etc. Include the plant name, plant ID, and pond/impoundment system ID or wastewater treatment system ID in the upper right hand corner of the diagram.
			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 Tables Table D-5 and Table D-9.
				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 Table D-3 in Question D2-2. 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.
			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.
			Review:
			If any of the statements above were not checked, revise the block diagram(s) and ensure all statements have been checked.
			Example EPA_D-1. Block Diagram for FGD Wastewater Treatment System
			Example EPA_D-2. Block Diagram for Ash Pond System
			NOTE: The codes used in these diagrams correspond the code tables on the "Code Tables" tab provided at the end of this workbook.
