PART F. MANAGEMENT PRACTICES FOR PONDS/IMPOUNDMENTS AND LANDFILLS
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.
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 “N/A” 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.

Section Title:

4.1. Leachate Treatment System Design

Instructions:

Complete Section 4.1 (Question F4-1and F4-2) for all leachate treatment systems (as specified in Question F2-8 and F3-15) which the plant operates or plans to operate or construct/install by December 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 information for those systems in this section. Refer to your responses to Questions F2-8 and F3-15 to identify the systems that need to be included in this table. Please provide all free response answers in the highlighted yellow areas.

CBI?

F4-1.

In Table F-4, list all leachate treatment systems (as specified in Question F2-8 and F3-15), 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-4, 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-4 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.

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 similar level of detail as 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.

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.

If a process operation does not have an EPA-assigned number, 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" tab provided at the end of this workbook. Note that the codes listed in the "Wastewater Treatment Unit" table on the "Code Tables" tab should be used for assigning the leachate treatment units.

Indicate where chemical addition occurs (i.e., into or between which leachate treatment units). For constructed wetland treatment cells, indicate and note on the diagram where within or near the 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-8.

Identify the final, general destination of the treated leahate (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.

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-5 in Question F3-3. 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”.

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.
