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 

“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.

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.
