"*" 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
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 the 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.
g Chemical-specific properties
					 are such that this route is not of concern at any soil contaminant
					 concentration.
h40 CFR 761 contains
					 applicability requirements and methodologies for the development of PCB
					 remediation objectives. Requests for approval of a Tier 3 evaluation must
					 address the applicability of 40 CFR 761.
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 of
					 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; (2) where applicable, 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
					 ); or (3) the appropriate background value listed in Appendix A, Table G. 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 procedures set forth in Subparts D and I of this
					 Part.
