Current through Register Vol. 48, No. 38, September 20, 2024
A site investigation shall be performed under this Part to
identify, as indicated within the RA's application for review and evaluation
services, all or specified recognized environmental conditions existing at the
remediation site, the related contaminants of concern, and associated factors
that will aid in the identification of risks to human health, safety and the
environment, the determination of remediation objectives, and the design and
implementation of a Remedial Action Plan.
a) If the RA has elected under the
application for review and evaluation services to obtain a No Further
Remediation Letter covering all recognized environmental conditions and related
contaminants of concern for the remediation site, then the procedures provided
under Sections
740.420
and
740.425
of this Part shall be followed.
b)
If the RA has elected under the application for review and evaluation services
to obtain a No Further Remediation Letter covering a limited number of
recognized environmental conditions and related contaminants of concern as
specified by the RA, then the procedures at Sections
740.430
and
740.435
of this Part shall be followed.
c)
The RA may revise an election at any time by initiating a modification of the
Review and Evaluation Services Agreement under Section
740.220
of this Part and performing the appropriate site investigation, if
necessary.
d) Site investigations
shall satisfy the following data quality objectives for field and laboratory
operations to ensure that all data is 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
740.125
of this Part. If approved by the Agency, 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), "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),
incorporated by reference at Section
740.125
of this Part, 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 "Test Methods
for Evaluating Solid Waste, Physical/Chemical Methods" (SW-846), Vol. One, Ch.
One (Quality Control), incorporated by reference at Section
740.125
of this Part, or with an equipment or instrument manufacturer's or vendor's
published standard operating procedures.
3) All laboratory quantitative analysis of
samples to determine concentrations of regulated substances or pesticides shall
be conducted fully in accordance with "Test Methods for Evaluating Solid Waste,
Physical/Chemical Methods" (SW-846), incorporated by reference at Section
740.125
of this Part, 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 most protective Tier 1 soil remediation objectives in 35 Ill. Adm.
Code 742.Appendix B, applicable groundwater remediation objectives under 35
Ill. Adm Code 742.Appendix B, or, if already determined, the remediation
objective concentrations for the site. If a contaminant of concern is not
identified in Part 742 or the remediation objectives for the site have not been
determined, the PQL shall equal the lowest concentration that reliably can be
achieved within specified limits of precision and accuracy during routine
laboratory operating conditions but shall not be greater than ten times the
method detection limit.
4) All
field or laboratory measurements of samples to determine physical or
geophysical characteristics shall be conducted in accordance with ASTM
standards or other procedures as approved by the Agency.
5) All laboratory quantitative analyses of
samples to determine concentrations of any regulated substances or pesticides
that require more exacting detection limits or cannot be analyzed by standard
methods identified in "Test Methods for Evaluating Solid Waste,
Physical/Chemical Methods" (SW-846), incorporated by reference at Section
740.125
of this Part, shall be conducted in accordance with analytical protocols
developed in consultation with and approved by the Agency.
6) Effective January 1, 2003, all
quantitative analyses of samples collected on or after that date and 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.
