PART G. LEACHATE SAMPLING DATA FOR PONDS/IMPOUNDMENTS AND 

LANDFILLS

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

requested in certain questions within Part G; indicate atypical data (e.g., if the analytical 

data provided from the sample collection 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 G 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 G TOC tab, all name and ID fields throughout Part G will automatically populate. 

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

assistance with completing Part G. 

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

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

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

and landfill names 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 landfill.

Sampling data and the completed Part G of the questionnaire shall be submitted 

to EPA no later than 120 calendar days after receiving the questionnaire. 

A company or plant may be exempt from the leachate sample collection (Question G3-

1). Please refer to Question G1-1 and the "Applicability" section located in the "Part G 

Section 3" tab to determine if you are exempt and how to submit a written explanation.
