Illinois Administrative Code › Title 8 - AGRICULTURE AND ANIMALS › Part 259 - AGRICHEMICAL FACILITY RESPONSE ACTION PROGRAM › Subpart C - SITE ASSESSMENT › Section 259.310 - General

Current through Register Vol. 48, No. 28, July 12, 2024
An owner or operator who elects to participate in the
				  Agrichemical Facility Response Action Program shall conduct site assessments
				  pursuant to this Subpart. The purposes of the site assessment are to identify
				  any agrichemical contamination of soil or groundwater and to develop sufficient
				  information regarding the extent of any contamination to guide decisions about
				  corrective actions. The findings, opinions and conclusions of the site
				  assessment shall be supported by adequate documentation. All site assessment
				  activities shall be conducted by or under the supervision of a licensed
				  professional geologist, professional engineer or licensed industrial hygienist.
				  An applicant may request the Department's assistance in investigating suspected
				  site contamination.
a) The results of
				the initial assessment pursuant to Section
				259.320 of
				this Part and plans to conduct sampling and analyses shall be submitted to the
				Department and the Board for review. The results of the final site assessment
				pursuant to Section
				259.330 of this
				Part shall also be submitted. Both phases may be conducted and the combined
				results submitted for review. Based on the results of the initial site
				assessment, the Department may recommend the addition or deletion of compounds
				from the list of target pesticides and recommend collection and analyses of
				groundwater samples.
b) All field
				and laboratory activities shall 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 shall be conducted in
				accordance with "Test Methods for Evaluating Solid Waste, Physical/Chemical
				Methods" (SW-846), Vol. One, Ch. One (Quality Control) and Vol. Two (Field
				Manual), incorporated by reference at Section
				259.150
				of this Part. If approved by the Department, such activities also may be
				conducted in accordance with ASTM standards; methods identified in "A
				Compendium of Superfund Field Operations Methods" (EPA/540/0-87-001, OSWER
				Directive 9355.0 -14, December 1987), "Subsurface Characterization and
				Monitoring Techniques: A Desk Reference Guide, Volume I: Solids and Ground
				Water, Appendices A and B" (EPA/625/R-93/003a, May 1993), or "Subsurface
				Characterization and Monitoring Techniques: A Desk Reference Guide, Volume II:
				The Vadose Zone, Field Screening and Analytical Methods, Appendices C and D"
				(EPA/625/R-93/003b, May 1993); or other procedures.
2) All field measurement activities relative
				to equipment and instrument operation, calibration and maintenance, corrective
				action, and data handling shall 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
				agrichemicals shall 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 shall be less than or equal to the default
				SCO contained in Appendix B of this Part, or, if site-specific cleanup
				objectives have been determined, the PQL shall be less than or equal to the
				site-specific SCOs for the site.
4)
				All field or laboratory measurements of samples to determine physical or
				geochemical characteristics shall be conducted in accordance with ASTM
				standards or other procedures as approved by the Department.
5) All laboratory quantitative analyses of
				soil samples to determine concentrations of any regulated substances or
				agrichemicals that require more sensitive detection limits or cannot be
				analyzed by standard methods identified in SW-846 shall be conducted in
				accordance with analytical protocols developed in consultation with and
				approved by the Department.
6) All
				groundwater monitoring and analytical procedures shall be conducted in
				accordance with 35 Ill. Adm. Code
				620.505
				and
				620.510.
7) All quantitative analyses of soil and
				groundwater samples utilizing 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.
