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: W hen 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.

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-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.

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.

**CBI? F4-4.**  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 W WTSystem” 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.
