PART F. MANAGEMENT PRACTICES FOR PONDS/IMPOUNDMENTS AND 

LANDFILLS

Throughout Part F Section 4, information is requested on leachate treatment units and 

systems that are planned, under construction/installation, or planned to begin 

construction/installation by December 31, 2020. Provide design information, or best 

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

“NA” in the field or checkbox if the information requested is not applicable for planned 

systems/units (e.g., a question that requests flow rate data for year 2009).

Use the Part F Comments tab to do the following: provide additional information as 

requested in certain questions within Part F; 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 F 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 F TOC tab, all name and ID fields throughout Part F will automatically populate. 

Refer to the overall questionnaire instructions, the glossary, and the acronym list for 

assistance with completing Part F. 

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

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

provided throughout Part F regarding making copies. Note that pond/impoundment unit, 

landfill, leachate treatment system, and leachate treatment unit names or IDs 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.

1. Pond/Impoundment and Landfill Use

Part F requests information for all active/inactive/open and retired/closed pond/impoundment units and landfills , 

including those located on non-adjoining property, used 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 or petroleum coke, including, but not limited to, fly ash , bottom ash , boiler slag, or flue gas emission 

control residues. This includes liquid-borne material and solid material.

those located on non-adjoining property, used 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 or petroleum coke, including, but not limited to, fly ash, bottom ash, boiler slag, or flue gas emission control 

residues (this includes liquid-borne material and solid material)? [Check the box below.]

31, 2020. Note that wastewater treatment systems previously defined in Table D-2 that receive pond/impoundment or landfill leachate should NOT be included in this table and you do not need to provide

in the highlighted yellow areas.

Approximate Distance 

to Final Outfall (ft)

In Table F-5, list all leachate treatment systems (as specified in Question F2-7 and F3-14), not including wastewater treatment systems previously defined in Table D-2, which the plant operates or plans to 

operate. For each leachate treatment system, EPA assigned a number (e.g., LTS-1, LTS-2) in Table F-5, which will be used throughout the remainder of the survey. In the “Plant Designation” column, 

provide the plant’s name for each leachate treatment system. As an example, if a plant operates a chemical precipitation leachate treatment system that discharges to an ash pond/impoundment system, 

the leachate treatment system should be identified in Table F-5 as LTS-1 and the ash pond/impoundment system should have been previously identified in Table D-1. For each planned leachate treatment 

system, provide an estimate of the expected average annual flow rate of the effluent from the treatment system.

constructed wetland treatment cell the chemical is added (e.g., within the constructed wetland treatment cell near the leachate influent point, within the constructed wetland treatment cell near the 

effluent, in the effluent/discharge canal). The chemicals indicated should correspond to the chemicals listed in Table F-9.

Indicate, as appropriate, where treated leachate 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 leachate treatment system on the diagram (in gpm or gpd). For planned leachate treatment systems, 

provide the design flow rates for the system. Note that these should be the same flow rates that are entered into Table F-6 in Question F4-3. 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 leachate stream is intermittent, provide amount and frequency; for 

example “100 gal, twice/day, 100 dpy” or “1000 gpm, 4 hpd, 365 dpy”.

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 leachate treatment system ID on the diagram.

Include each leachate treatment unit operation. Show all influent and effluent streams from the units and label all influent and effluent streams from the leachate treatment system using the codes 

on the "Code Tables" tab provided at the end of this workbook. Effluent streams may include process wastewater and sludges . 

Attach a block diagram that shows the leachate treatment operations, the process wastewaters that currently enter or are planned to enter the leachate treatment system, and the ultimate destinations of 

the leachate treatment system effluent(s). Specific instructions for the diagram are provided in the checklist below. The diagram should have a level of detail similar to EPA’s Example EPA_F-1 shown 

below.

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 F-1, 

the second F-2, etc. Include the plant name, plant ID, and leachate treatment system ID in the upper right hand corner of the diagram. 

Identify the final, general destination of the treated leachate (e.g., treated leachate effluent to POTW or surface waters; solid wastes to on- or off-site destinations). Use codes from the "Code 

Tables" tab provided at the end of this workbook, when applicable.

4.3. Leachate Treatment System Units

In Table F-7, list all leachate treatment units comprising the leachate treatment system including units that are operating, under 

construction/installation, or planned to be constructed/installed by December 31, 2020. For each leachate treatment unit, assign an ID using the 

leachate treatment unit ID options presented in the drop-down box; however, if a pond/impoundment unit is included as part of the leachate 

treatment system, enter the pond/impoundment unit ID assigned in Table A-4 in the space labeled "Pond ID". The drop-down menu accounts for 

the possibility of multiple leachate treatment system units; they are numbered sequentially. Note that these terms originated from the code tables 

on the "Code Tables" tab, provided at the end of this workbook. For example, if the leachate treatment system includes two clarifiers, select 

Clarification, Primary-1 for the first clarifier and Clarification, Secondary-1 for the second. In the “Plant Designation” column, provide the plant’s 

name for each leachate treatment unit. In the “Date Added to WWT System” column, either enter the date the unit was/will be installed if the unit 

is a retrofit, or enter “original” if the unit was part of the original wastewater treatment system installation.

Note: A constructed wetland cell is considered one leachate treatment unit. 

Complete Section 4.3 (Questions F4-4 through F4-7) for each leachate treatment system identified in Table F-5, including systems that are 

planned, under construction/installation, or planned to be constructed/installed by December 31, 2020. Enter the leachate treatment system ID in
