UNITED STATES ENVIRONMENTAL PROTECTION AGENCY '£ 3&P 9 & ^^
WASHINGTON, D.C. 20460 :
OFFICE OF
SOLID WASTE AND EMERGENCY
RESPONSE
Dear Colleague: AUG - 6 1999
This letter transmits an Errata to the publication "-Human health Risk Assessment
Protocol for Hazardous Waste Combustion Facilities" (peer review draft, EPA530-D-98-001 A,
B & C) dated July 1998. In addition, it will serve to update you on the status of the protocol's
finalization.
The risk assessment guidance became available for use via a Federal Register Notice on
Friday, October 30, 1998. A public comment period was opened on that date as well. Since that
time, the protocol has been used in a number of site-specific risk assessments on RCRA
hazardous waste combustors. Additionally, a large number of comments were received through
the public comment period. Consequently, this errata is a result of a combination of issues raised
during implementation, as well as incorporation of relevant points which were raised during the
comment period. We recommend that these corrections be used in conjunction with the protocol
until the Office of Solid Waste is able to release a final protocol.
Please be aware, that due to the number and complexity of the comments received on the
document, we still have a number of issues which have not been addressed by this errata. We are
continuing to work through the unresolved issues at this time, but feel this interim measure is
warranted to insure that any pending or future risk assessments.have the advantage of this
information. In addition, we will be sending the protocol (along with this errata) for an
independent, exterior peer review within the next few months. ;We will address any outstanding
public comments, as well as recommendations received from the peer review in a final
document.
If you have any question or concerns on this matter, please contact Karen Pollard of my
staff at (703) 308-3948 or Jeffi-ey Yuxk of Region 6 at (214) 665-8309.
Sincerely;
Barnes Johnson, Director

Human Health Risk Assessment Protocol for
Hazardous Waste Combustion Facilities (Peer Review Draft)
Errata - August 2,1999
General Comments
i |
Reference materials:
Numerous comments have been received challenging a number of physical/chemical parameters
and toxicity values that are in the peer review draft version of the "Human Health Risk
Assessment Protocol for Hazardous Waste Combustion Facilities ". Since this protocol is a
"snap shot" of risk assessment science at the time of its publication, it is possible (even probable)
that a number of the parameters and toxicity values and their reference materials have been
updated and/or revised. Therefore, when using the protocol, the risk assessor should verify the
information and references to determine if they are still valid. The Office of Solid Waste (OSW)
will continue to review all reference materials used while finalizing the protocol and change
those which we deem necessary. Until that time, however, we provide the list below of
documents which have been revised or finalized and are not currently reflected in the protocol.
These documents are:
1. "The Determination of Acute Reference Exposure Levels for, Airborne Toxicants" (SRP
Review Draft, October 1998). This is a document that has acute toxicity levels (RELs) which
may be different then those currently reflected in the protocol. This document can be found on
the web at www.oehha.ca.gov/scientific/acuterel.htni. .
2. "Soil Screening Guidance " (publication 9355.4-23 July 1996). Currently, the protocol
references a 1994 draft of this document. This is document can be found at
http://www.epa.gov/oerrpage/superfund/resources/soil/toc.htm
3. "Superfand Chemical Data Matrix" (publication 9345.1-21, EPA 540/R-96/028, June 1996).
The data base can be down loaded from the OSWER web site at
www.epa.gov/oerrpage/superfund/resoarces/scdm/index.htm. '
Changes to Volume Two. Appendix A
NCEA provision toxicity values:
Please note, that a number of the toxicity values that have beeri changed in the table below
reference a National Center for Exposure Assessment (NCEA) provisional number. The risk
assessor should always check with their permitting authority on the validity and appropriateness
of the provisional number prior to use.

Changes to Volume 3. Appendix B
Loss Due to Volatilization from soil (ksv):
The following equation should be used to update the soil loss due to volatiliztion equations in
Appendix B, Table B-3-6. This change is based pn the document entitled "Methodology for
Assessing Health Risks Associated with Multiple Exposure Pathways to Combustor Emissions
(U.S. EPA In Press). This will replace the ksv default of 0 which is currently recommended.
The soil loss constant due to volatilization (ksv) is based on gas equilibrium coefficients (Ke)
and gas phase mass transfer (Kt). The first order decay constant, Ksv, is obtained by adapting
the Hwang and Falco equation for soil vapor phase diffusion (Hwang and Falco, 1986).
ksv = Ke Kt
where:
ksv = soil loss constant due to volatilization (yr1)
Ke = equilibrium coefficient (s/yr-cm)
Kt = gas phase mass transfer coefficient (crn/s)
The equilibrium coefficient (Ke) is calculated using the following equation:
Page 17 of 20
-------
_ 3.1536E+7 H
"" <>v ~~~ ~ ZT Z
where:
Ke = equilibrium coefficient (s/yr-cm)
3.1536E+7 = units conversion factor ([3.1536E+7 sec/yr])
H = Henry's Law constant (atm-m3/mol)
2s = soil mixing zone depth (cm)- 1cm.for untilled soil; 20 cm for
tilled soil
K * = organic carbon partition coefficient (mL/g)
f * = fraction of organic carbon in soil (unitless)
R = ideal gas constant (atm-m3/mol-K) - 8.205 E -05 atm-m3/mol-K
Xa = temperature (K) - 298 K (ambient)
BE) = bulk density of soil (g/cm3) - 1.5 g/cm3
*Note: K x f^ = Kds cm3/g - Kds values are COPC-specific and provided in Appendix A
The gas-phase mass transfer coefficient (KJ is based on general soil properties (Hillel, 1980;
Miller and Gardiner, 1998) which can be used to calculate the following equation:
K *
*, =

Kt = gas phase mass transfer coefficient (cm/s)
Zj = soil mixing depth (cm)
Da = diffusion coefficient of contaminant in air (cm2/s)
0V = soil void fraction (cmVcm3)
The soil void fraction( 6v) is the volumetric fraction of a soil that does not contain solids or
water.
Qv = 1 -
where:

6V = soil void fraction (cmVcm3)
0SW = volumetric soil water content (mL (=cm3 )/cm3) - 0.2 mL/cm3
BD = soil bulk density (g/cm3) - 1.5 g/c:m3 ;
ps = solids particle density (g/cm3) - 2.7 g/cm3
The expression containing bulk density (BD) divided by solids particle density (ps) gives '
the volume of soil occupied by pore space or voids (Miller and Gardiner, 1998). Soil bulk
density is affected by the soil structure, such as looseness or cc-mpaction of the soil, depending
on the water and clay content of the soil (Hillel 1980). A range of 0.83 to 1.84 was originally
cited in Hoffman and Baes (1979). A default soil bulk density of 1.5 g/cm3 is recommended in
the HHRAP based on a mean value for loam soil from Carsel et al. (1988). Blake and Hartge
(1996) and Hillel (1980) both suggests that the mean density of solid particles is about 2.7
gm/cm3. The soil water content depends on both the available water and the soil structure of a
particular soil. Values for 0SW range fiom 0.03 to 0.40 mL/cm3 depending on soil type (Hoffman
and Baes, 1979). The lower values are typical of sandy soils, which cannot retain much water;
the higher values are typical of soils such as clay or loam soils which can retain water. A mid-
point default value of 0.2 mL water/crn3 soil is recommended in the HHRAP. Since the soil
water content of soil is unique for each soil type, site-specific information is highly
recommended.

Air Density:
In Table B-3-8 of Appendix B the density of air (p) default value should be changed from 0.0012
to 1200. The change is the result of a units correction from g/cm3 to g/m3.
Mercury:

modeled by applying the equations in Table B-4-10 and Table B-4-11, respectively. These
equations (as written) do not account for the increase in methylation that occurs as the divalent
mercury fraction from pervious runoff and erosion enters the water body. (Consequently, the
following step are recommended.
To account for methylation of LR (runoff load from pervious surfaces) entering the water body,
values for LR(/mria0 are calculated for divalent mercury (Hg2+ - modeled as mercuric chloride) and
methyl mercury (MHg) using their respective Cs and Kds values as entered into the equation in
Table B-4-10. Then, as indicated below, LR(Mliaf) values should be apportioned based on an 85%
Hg2+ and 15% MHg speciation split in the water body (consistent with Chapter 2 of the HHRAP)
to obtain LR(fiBfl0 values.

After calculating species specific final LR and LE values, divalent and methyl mercury should
continue to be modeled throughout Appendix B equations as individual COPCs.
Changes to Volume Three. Appendix C
COPC intake from soil:
In table C-l-1 of volume three, the soil consumption rate (CRsoii) for the adult and child should
be changed to 0.0001 kg/day and 0.0002 kg/day, respectively. These changes are based on the
recommendation in the final draft of the Exposure Factors Handbook that a conservative
estimate of the mean be used. The previous number was based on an earlier draft of the
Exposure Factors Handbook, the new value reflects the recommendation made in the final draft.
