Illinois Administrative Code › Title 8 - AGRICULTURE AND ANIMALS › Part 258 - LAND APPLICATION AUTHORIZATION PROGRAM › Section 258.90 - Sampling and Analysis

Current through Register Vol. 48, No. 28, July 12, 2024
a)
			 Contaminated soil or groundwater must be sampled in accordance with the
			 requirements of this Part and analyzed for the presence and concentration of
			 the target agrichemicals included on the list of compounds required in 8 Ill.
			 Adm. Code
			 255.50(a).
			 Soil samples may be composited. At least one composite soil sample is required
			 per one-eighth acre of the spill site, using six subsamples per
			 composite.
b) Soil samples from the
			 land application area, excluding field access lanes, must be collected to the
			 depth of incorporation or three inches, whichever is less. Soil samples from
			 field access lanes must be collected to a depth of six inches.
c) Soil samples collected from the land
			 application area must be analyzed for the agrichemicals that were the basis for
			 determining the application rate of the contaminated soil or groundwater
			 pursuant to Section
			 258.70(e).
d) Sampling of the land application area must
			 be conducted in accordance with Appendix D of this Part, except field access
			 lanes that must be sampled at the rate of at least one composite soil sample
			 per 500 lineal feet.
e) All field
			 and laboratory activities must satisfy the following to ensure that all data
			 are scientifically valid and of known precision and accuracy:
1) All field sampling activities relative to
			 sample collection, documentation, preparation, labeling, storage, shipment and
			 security, quality assurance and quality control, acceptance criteria,
			 corrective action, and decontamination procedures must be conducted in
			 accordance with "Test Methods for Evaluating Solid Waste, Physical/Chemical
			 Methods" (SW-846), incorporated by reference at Section
			 258.40
			 of this Part.
2) All field
			 measurement activities relative to equipment and instrument operation,
			 calibration and maintenance, corrective action, and data handling must be
			 conducted in accordance with SW-846, or with an equipment or instrument
			 manufacturer's or vendor's published standard operating procedures.
3) All laboratory quantitative analyses of
			 soil samples to determine concentrations of pesticides must be conducted fully
			 in accordance with SW-846, relative to all facilities, equipment and
			 instrumentation, operating procedures, sample management, test methods,
			 equipment calibration and maintenance, quality assurance and quality control,
			 corrective action, data reduction and validation, reporting, and records
			 management. The practical quantitation limit (PQL) of the test methods selected
			 must be less than or equal to the RSDLs contained in Appendix A of this
			 Part.
4) All laboratory
			 quantitative analyses of soil samples to determine concentrations of pesticides
			 or nutrients must be conducted on the less than 2-mm fraction.
5) All laboratory quantitative analyses of
			 soil samples to determine concentrations of pesticides that require more
			 sensitive detection limits or cannot be analyzed by standard methods identified
			 in SW-846 must be conducted in accordance with analytical protocols developed
			 in consultation with and approved by the Department.
6) All groundwater monitoring and analytical
			 procedures must be conducted in accordance with 35 Ill. Adm. Code
			 620.505
			 and
			 620.510.
7) All quantitative analyses of soil and
			 groundwater samples that utilize any of the approved test methods identified in
			 35 Ill. Adm. Code
			 186.180
			 shall be completed by an accredited laboratory in accordance with the
			 requirements of 35 Ill. Adm. Code 186. Quantitative analyses not utilizing an
			 accredited laboratory in accordance with Part 186 shall be deemed
			 invalid.
