Chemical Abstracts Service (CAS) registry number. This
					 number in the format xxx-xx-x, is unique for each chemical and allows efficient
					 searching on computerized data bases.
a Soil remediation objectives
					 are determined pursuant to 40 CFR 761, as incorporated by reference at Section
					 742.210(b) (the USEPA "PCB Spill Cleanup Policy"), for most sites; persons
					 remediating sites should consult with BOL if calculation of Tier 2 or 3
					 remediation objectives is desired. PCBs are a mixture of different congeners.
					 The appropriate values to use for the physical/chemical parameters depend on
					 congeners present at the site.
b Dimensionless Henry's Law
					 Constant at 13°C is not calculated because the chemical is not volatile and
					 does not require evaluation under the indoor inhalation exposure route.
c Dimensionless Henry's Law
					 Constant = 20°C
d These chemicals are ionizing
					 and its Koc value will change with pH. The
					 Koc values listed in this table is the effective
					 Koc at pH of 6.8. If the site-specific pH is values
					 other than 6.8, the Koc value listed Appendix C, Table I
					 should be used.
e The values in this table were
					 taken from the following sources (in order of preference): SCDMS online
					 database (
http://www.epa.gov/superfund/sites/npl/hrsres/tools/scdm.htm
);
					 CHEMFATE online database (
http://www.srcinc.com/what-we-do/databaseforms.aspx?id=381
);
					 PhysProp online database (
http://www.srcinc.com/what-we-do/databaseforms.aspx?id-386
);
					 Water (
http://www.epa.gov/ttn/chief/software/water/
)
					 for diffusivity values; and Handbook of Environmental Degradation Rates by P.H.
					 Howard (1991) for first order degradation constant values.
