Insert Plant Name 3. Leachate Sample Collection Instructions OVERVIEW OF THE SAMPLE COLLECTION

The samples should be collected as detailed in these instructions. In general, samples should be collected as grab samples (i.e., composite samples arenot required). The plant should collect samples from each leachate collection point for each pond/impoundment and landfill. If the plant determines that a sample from one or more collection points are representative of an individual pond/impoundment or landfill, then the plant may simply collect the representative sample(s). The plant should collect samples from each sampling location once per w eek for four consecuti ve weeks, or as soon thereafter as sufficient leachate is available for collection. **Sampling data and the completed Part G of the questionnaire shall be submitted to EPA no later than 120 calendar day** **s after receiving the questionnaire.**  Collect process w astewater samples of untreated and/or treated leachate streams generated from pond(s)/impoundment(s) and landfill(s) used for the storage, treatment, or disposal of 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 desulfurization (FGD) sy stem residues (this includes liquid-borne material and solid material).

SAMPLE LOCATION Collect untreated and/or treated leachate samples from each pond/impoundment unit and landfill for w hich you responded "y es" in Question G2-1.

If the pond/impoundment unit and/or landfill has multiple collection points, the untreated sample may be collected from a common header area, if applicable. If there is not a common header area for the pond/impoundment or landfill, the plant may select one of the collection points that is "representative" of the pond/impoundment or landfill from w hich to collect the sample. If w arranted due to the characteristics of the pond/impoundment or landfill, the plant may need to collect samples from more than one collection point to obtain representative samples. If the plant collects the samples from one ”representative” collection point, describe how the company or plant determined the collection point is “representative” of all of the collection points in the “Part G Comments” tab located at the end of Part G. **If y ou believe y** **ou are exempt, y ou must submit a w**  **ritten explanation justify ing one or both of these tw**  **o circumstances within two weeks after receiving the questionnaire by** **e-mail (preferred) or mailed to:**

EPA w ill then determine if the plant is exempt from the leachate sample collection requirement. If the plant can provide previously collected leachate characterization data, then the plant should complete Section 4 (Questions G4-1 and G4-2) and continue to Section 5 (Question G5-1). Also, the plant must provide the leachate sampling data in Table G-4 found in the "Part G Sampling Results" tab. If the plant cannot collect the samples safely , then the plant should skip Section 4 and continue to Section 5 (Question G5-1).

The untreated leachate samples must be collected directly from the leachate collection system or holding tank prior to anyform of treatment. The treated leachate samples must be collected from the effluent from a leachate treatment sy stem that is designed for the purpose of removing pollutants or process w astewater constituents, other than suspended solids, prior to discharge or commingling wi th other process w astewaters.

### CBI? **G3-2.**

**CBI? G3-3.**  SAMPLE FREQUENCY Collect one sample of untreated leachate (and one sample of treated leachate if appropriatelyidentified by responses in Question G2- 4) once per w eek for four w eeks, or as soon thereafter as sufficient leachate is available for collection, from each pond/impoundment unit and landfill. Please note that the samples must be collected at least five day s after the previous sample w as collected. If the pond/impoundment or landfill does not generate leachate w eekly , please collect the samples as soon as the leachate is generated, but allow at least five day s between samples.

Please attach an aerial photograph or draw ing show ing the entire w aste management unit (i.e., pond/impoundment unit or landfill) that shows the boundaries and identifies all leachate collection points and the active and inactive areas of the pond/impoundment or landfill. Also, indicate the leachate sample location(s) used for this sample collection in the aerial photograph or draw ing of the pond/impoundment unit or landfill.
Please identify

the leachate sample locations used for this sample collection in the block diagram previously requested in Question F4- 2. QUALITY ASSURANCE/QUALITY CONTROL

Example 2: If a plant collects both untreated and treated leachate from both a pond/impoundment unit and a landfill, and each separately

has a single leachate collection point and they have separate treatment sy stems, the plant is required to collect a total of sixteen samples.

Follow the method-specified qualityassurance/qualitycontrol analy ses and attach a data reviewsummary once the analyses are complete. SAMPLE ANALYSES After receiving the analytical results from the laboratory , enter the analytical data into the “Part G Sampling Results” tab. Report all results, including those belowthe reporting limit. Identifyresults that are less than the method detection limit (MDL), and results that are between the detection and reporting limits . For example, if the MDL is equal to 5 ng/L, the reporting limit is equal to 15 ng/L, and the value reported bythe laboratory is 12 ng/L, report 12 ng/L as the measured value and identify and describe any qualifiers on the data in the corresponding column. If the measured value is not detected, list the detection limit value and select the less than (<) symbol in the non-detect indicator column.

Example1: If a plant collects only untreated leachate from a pond/impoundment unit, and the samples are obtained from a single leachate collection point, the plant is required to collect a total of four samples.
