Compare site data to remediation objectives
and determine:
1. Which COC's are below the Tier 1 objectives
2. Which COC's are still of concern
3. Can soil averaging or compositing be used
Remediate to
Tier 1

"*" indicates that the ADL is less than or equal to the specified remediation objective.
NA means Not Available; no PQL or EQL available in USEPA analytical methods.
Chemical Name and Soil Remediation Objective Notations (2nd, 5th thru 8th Columns)
a
Soil remediation objectives based on human health criteria only.
b
Calculated values correspond to a target hazard quotient of 1.
c
No toxicity criteria available for this route of exposure.
d
Soil saturation concentration (C
sat
)= the concentration at which the absorptive limits of the soil particles, the solubility limits of the available soil moisture, and saturation
of soil pore air have been reached. Above the soil saturation concentration, the assumptions regarding vapor transport to air and/or dissolved phase transport to
groundwater (for chemicals which are liquid at ambient soil temperatures) have been violated, and alternative modeling approaches are required.
e
Calculated values correspond to a cancer risk level of 1 in 1,000,000.
f
Level is at or below Contract Laboratory Program required quantitation limit for Regular Analytical Services (RAS).
g
Chemical-specific properties are such that this route is not of concern at any soil contaminant concentration.
h
A preliminary goal of 1 ppm has been set for PCBs based on
Guidance on Remedial Actions for Superfund Sites with PCB Contamination
, EPA/540G-90/007, and on
USEPA efforts to manage PCB contamination. See 40 CFR 761.120 for USEPA "PCB Spill Cleanup Policy." This regulation goes on to say that the remediation goal
for an unrestricted area is 10 ppm and 25 ppm for a restricted area, provided both have at least 10 inches of clean cover.
i
Soil remediation objective for pH of 6.8. If soil pH is other than 6.8, refer to Appendix B, Tables C and D in this Part.
j
Ingestion soil remediation objective adjusted by a factor of 0.5 to account for dermal route.
k
A preliminary remediation goal of 400 mg/kg has been set for lead based on
Revised Interim Soil Lead Guidance for CERCLA Sites and RCRA Corrective Action
Facilities
, OSWER Directive #9355.4-12.
l
Potential for soil-plant-human exposure.
m
The person conducting the remediation has the option to use: (1) TCLP or SPLP test results to compare with the remediation objectives listed in this Table; or (2) the
total amount of contaminant in the soil sample results to compare with pH specific remediation objectives listed in Appendix B, Table C or D of this Part. (See Section
742.510.) If the person conducting the remediation wishes to calculate soil remediation objectives based on background concentrations, this should be done in
accordance with Subpart D of this Part.
n
The Agency reserves the right to evaluate the potential for remaining contaminant concentrations to pose significant threats to crops, livestock, or wildlife.
o
For agrichemical facilities, remediation objectives for surficial soils which are based on field application rates may be more appropriate for currently registered
pesticides. Consult the Agency for further information.
p
For agrichemical facilities, soil remediation objectives based on site-specific background concentrations of Nitrate as N may be more appropriate. Such determinations
shall be conducted in accordance with the located in Subparts D and I of this Part.
q
The TCLP extraction must be done using water at a pH of 7.0.
r
Value based on dietary Reference Dose.
s
Value based on Reference Dose for Mercuric chloride (CAS No. 7487-94-7).
t
Note that Table value is likely to be less than background concentration for this chemical; screening or remediation concentrations using the procedures of Subpart D of
this Part.
u
Value based on Reference Dose for thallium sulfate (CAS No. 7446-18-6).

Chemical Name and Groundwater Remediation Objective Notations
a
The Equation S17 is used to calculate the Soil Remediation Objective for the Soil Component
of the Groundwater Ingestion Route; this equation requires calculation of the Target Soil
Leachate Concentration (C
w
) from Equation S18: C
w
= DF x GW
obj
.
b
Value listed is the Water Health Based Limit (HBL) for this chemical from Soil Screening
Guidance: User’s Guide, incorporated by reference at Section 742.210; for carcinogens, the
HBL is equal to a cancer risk of 1.0E-6, and for noncarcinogens is equal to a Hazard
Quotient of 1.0. NOTE: These GW
obj
concentrations are not equal to the Tier 1 Groundwater
Remediation Objectives for the Direct Ingestion of Groundwater Component of the Groundwater
Ingestion Route, listed in Section 742.Appendix B, Table E.
c
Value listed is also the Groundwater Quality Standard for this chemical pursuant to 35 Ill.
Adm. Code 620.410 for Class I Groundwater or 35 Ill. Adm. Code 620.420 for Class II
Groundwater.

Section 742.APPENDIX C: Tier 2 Tables and Illustrations
Section 742.Illustration B: Tier 2 Evaluation for Groundwater
Identify contaminants of concern which
exceed the Tier 1 groundwater
remediation objectives
Determine the horizontal and vertical
extent of the area the Tier 2 objective
is to be applied
Take action to remove any free product
Demonstrate all of the following:
contaminant
level will not
exceed the
Tier 1 level or
health
advisory at the
point of
human
exposure
contaminant
level will not
exceed Tier
1 levels
within a
setback
zone
contaminant
level will not
exceed surface
water quality
standards at any
discharge point
the source of
the release is
not within a
setback zone
or regulated
recharge area
institutional
controls are
in place if
engineered
barriers are to
be used
Develop a Tier 2 groundwater
remediation objective
(cannot not exceed the water
solubility of the contaminant)
Are the Tier 2
remediation objectives
achieved?
No Further Remediation
Yes
No
Conduct remediation
or a Tier 3 evaluation

Soil remediation objectives are determined pursuant to 40 CFR 761.120, as incorporated by reference at Section 732.104 (the USEPA "PCB Spill Cleanup Policy"), for most sites; persons remediating
sites should consult with BOL if calculation of Tier 2 soil remediation objectives is desired.
