		Part:	G
		Section Title:	3. Leachate Sample Collection Instructions
		G3-1.	OVERVIEW OF THE SAMPLE COLLECTION
			Collect process wastewater 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) system residues (this includes liquid-borne material and solid material).
			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.
			The samples should be collected as detailed in these instructions. In general, samples should be collected as grab samples (i.e., composite samples are not 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 week for four consecutive weeks, or as soon thereafter as sufficient leachate is available for collection.
			The following analytes and analytical methods must be used for the sample analysis:
					• Metals (total recoverable; antimony, arsenic, beryllium, cadmium, chromium, cobalt, copper, lead, manganese, molybdenum, nickel, selenium, silver, thallium, vanadium, and zinc)	EPA Method 200.8
					• Metals (total recoverable: aluminum, barium, boron, calcium, iron, magnesium, sodium, tin, and titanium)	EPA Method 200.7 or 200.8
					• Mercury	EPA Method 1631E
					• Chlorides	40 CFR Part 136-approved method
					• Sulfates	40 CFR Part 136-approved method
					• Total dissolved solids (TDS)	40 CFR Part 136-approved method
					• Total suspended solids (TSS)	40 CFR Part 136-approved method
					• pH	40 CFR Part 136-approved method
			Each company or plant is responsible for identifying and contracting an analytical laboratory to perform the analyses.
			APPLICABILITY
			A plant may be exempt from the leachate sample collection (and skip to Question G3-2) if one of these two circumstances is true:
				1. The plant can provide previously collected leachate characterization data if it fulfills the following data requirements:
					• Must have data from leachate generated from each pond/impoundment and landfill where leachate is collected; • Must have at least four samples of untreated and/or treated leachate, where each sample is collected at least five days apart; and • Must have tested for every analyte listed above using the specified analytical methods.
				2. The plant personnel are unable to collect the samples safely.
			If you believe you are exempt, you must submit a written explanation justifying one or both of these two circumstances within two weeks after receiving the questionnaire by e-mail (preferred) or mailed to:
					Jezebele Alicea US EPA Engineering and Analysis Division Mail Code: 4303T 1200 Pennsylvania Avenue, N.W. Washington, DC 20460 alicea.jezebele@epa.gov
			EPA will 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 skip 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 complete Question G4-1, then continue to Section 5 (Question G5-1).
			SAMPLE LOCATION
			Collect untreated and/or treated leachate samples from each pond/impoundment unit and landfill for which you responded "yes" in Question G2-1.
			The untreated leachate samples must be collected directly from the leachate collection system or holding tank prior to any form of treatment. The treated leachate samples must be collected from the effluent from a leachate treatment system that is designed for the purpose of removing pollutants or process wastewater constituents, other than suspended solids, prior to discharge or commingling with other process wastewaters.
			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 which to collect the sample. If warranted 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.
			SAMPLE FREQUENCY
			Collect one sample of untreated leachate (and one sample of treated leachate if appropriately identified by responses in Question G2-4) once per week for four weeks, 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 days after the previous sample was collected. If the pond/impoundment or landfill does not generate leachate weekly, please collect the samples as soon as the leachate is generated, but allow at least five days between samples.
				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.
				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 systems, the plant is required to collect a total of sixteen samples.
			SAMPLE ANALYSES
			After receiving the analytical results from the laboratory, enter the analytical data into the “Part G Sampling Results” tab. Report all results. Identify results that are less than the method detection limit (MDL), and results that are between the detection and reporting limits.
			QUALITY ASSURANCE/QUALITY CONTROL
			Follow the method-specified quality assurance/quality control analyses and attach a data review summary once the analyses are complete.
	CBI?	G3-2.	Please attach an aerial photograph or drawing showing the entire waste 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 drawing of the pond/impoundment unit or landfill.
	CBI?	G3-3.	Please identify the leachate sample locations used for this sample collection in the block diagram previously requested in Question F4-2.
