Current through Register Vol. 48, No. 38, September 20, 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.
