I. INTRODUCTION
A. Overview of Volume V
The Human Health Risk Assessment (HHRA) portion of the WTI Risk Assessment
involves the integration of information about the facility with site-specific data for the
surrounding region and population to characterize the potential human health risks due to
emissions from the facility. The estimation of human health risks is comprised of the
following general steps: 1) identification of substances of potential concern; 2) estimation of
the nature and magnitude of chemical releases from the WTI facility; 3) prediction of the
atmospheric transport of the emitted contaminants; 4) determination of the types of adverse
effects associated with exposure to the substances of potential concern (referred to as hazard
identification), and the relationship between the level of exposure and the severity of any
health effect (referred to as dose-response assessment); 5) estimation of the magnitude of
exposure (referred to as exposure assessment); and 6) characterization of the health risks
associated with exposure (referred to as risk characterization).
( Volume m of the WTI Risk Assessment identifies the chemicals that may be released
from the WTI facility, both from the incinerator stack and from fugitive sources (step 1).
These chemicals (referred to as substances of potential concern)—which include metals,
dioxins/furans, products of incomplete combustion, acid gases, and paniculate matter—are
summarized in Tables 1-1 and 1-2 for substances emitted from the stack and for fugitive
emissions, respectively. Estimates of chemical-specific emission rates and the prediction of
atmospheric concentrations and deposition of the substances of potential concern in the
vicinity of the site (steps 2 and 3) are provided in Volumes ffl and IV, respectively. Using
this information, Volume V describes the techniques used in partitioning the substances of
potential concern into different environmental compartments (e.g., soil, vegetables, etc.),
calculating human exposure, and characterizing health risks to individuals and population
subgroups living and working in the vicinity of the WTI facility! In addition, within each
chapter of the HHRA, a summary of the sources of uncertainty and a qualitative discussion
of these uncertainties is provided, with a more detailed, quantitative analysis of uncertainties
and the effect on estimated risks provided following the risk characterization chapter.
The approach used in the HHRA is designed to provide estimates of: (1) individual risk
based on central tendency exposure (within subareas surrounding the facility) and at
^-,, maximum points within each subarea; (2) risks to highly exposed or susceptible subgroups of

-------
the population (e.g., subsistence farmers and school children); (3) risks associated with
specific activities that may result in elevated exposures (e.g., subsistence fishermen and deer
hunters); and (4) population risk. In addition, for those subgroups of the population that are
estimated to be more highly exposed, a sensitivity analysis is conducted to evaluate potential
variabilities in exposure (e.g., "high-end" exposure).
The estimation of risks is achieved by subdividing the area most affected by emissions
from WTI into subareas, and identifying subgroups to completely characterize the population
in the area. In doing so, this approach allows for the estimation of risk to specific segments
of the population taking into consideration activity patterns, number of individuals, and actual
locations of individuals in these subgroups with respect to the site.
The methodologies used in estimating exposure and risks to identified subgroups in the
vicinity of the WTI facility are contained in subsequent chapters and the associated
appendices as follows:
Chapter n: Risk Assessment Methodology - which describes the steps and the guidance
relied upon to conduct the HHRA;
Chapter ffl: Toxicity Assessment - in which measures of the human toxicity of substances
of potential concern are identified;
Chapter IV: Selection of Surrogate Chemicals - in which a subset of the organic
compounds released from the facility are selected for evaluation in the HHRA
in order to focus the assessment on the chemicals with the greatest potential
for risk;
Chapter V: Identification of Exposure Pathways and Populations - which identifies groups
within the population living and working in the vicinity of the facility who
may be exposed to emissions from WTI and the potential routes by which an
individual may be exposed;
Chapter VI: Estimation of Environmental Concentrations - which describes the techniques
used to estimate the fate and transport of site-related substances in the
environment;
Chapter VH: Estimation of Human Exposure - which describes the methodology used to
estimate exposure to subgroups of the population through exposure pathways
identified in this chapter;
Chapter VDI: Human Health Risk Characterization - in which numerical estimates of
carcinogenic risk and the potential for noncancer health effects are calculated
for individual subgroups within the surrounding population, and for the
population as a whole within the risk assessment study area;

H. RISK ASSESSMENT METHODOLOGY
The HHRA for the WTI facility consists of the evaluation of potential human health
risks associated with exposure to incinerator stack and fugitive emissions produced during
routine operation of the facility. A brief introduction to the general risk assessment process
and recent U.S. EPA guidance relevant to the assessment of risks from indirect exposure to
incinerator emissions is presented in the following sections.
A. The Risk Assessment Process
The foundation for the risk assessment methods described in this report is consistent
with well-established chemical risk assessment principles and procedures developed for the
regulation of environmental contaminants (NRC 1983, OSTP 1985, U.S. EPA 1986a,b).
Application of these guidelines and principles provides a consistent process for evaluating
and documenting potential health risks associated with environmental exposures.
The risk assessment process used by federal regulatory agencies and applied in this
f~^ assessment is essentially that described by the National Research Council (NRC 1983), and
'" "^ consists of the following four components:
• Hazard identification, in which the chemical substances of concern in emissions
from the facility are identified and data relevant to the toxic properties of these
substances are compiled, reviewed, and evaluated;
• Dose-response evaluation, in which the relationship between dose and response is
evaluated for each chemical of potential concern to derive toxicity values that can
be used to estimate the incidence of adverse effects occurring at different exposure
levels;
• Exposure assessment, in which potential exposure pathways are identified and
measures of chemical exposure (e.g., concentrations for the various environmental
media, or doses) are estimated for the potential exposure pathways, based upon
various exposure assumptions and the characteristics of the population receiving
the exposure; and,
External Review Draft

-------
• Risk characterization, in which numerical estimates of risk are calculated for each
substance by each potential route of exposure using the toxicity information and
the exposure estimates.
In addition to the steps listed above, the HHRA characterizes uncertainty associated
with each step of the process and includes an analysis of the potential effects of the
individual sources of uncertainty as part of the risk characterization.
It should also be noted that in the HHRA, the first two steps of the risk assessment
process, hazard identification and dose-response assessment, are simplified by using toxicity
information compiled by U.S. EPA. This information is typically used in conducting risk
assessments where a significant number of common environmental contaminants are being
evaluated. The combination of these steps in this assessment is referred to as the Toxicity
Assessment.
B. Other U.S. EPA Guidance Documents
In conducting the HHRA, various sources of U.S. EPA guidance are relied upon that
are specific to incineration or provide recent guidance on some aspect of the risk assessment
process (e.g., exposure assessment). As previously emphasized, U.S. EPA guidance is used
in conjunction with site-specific data and information to the extent possible.
• The primary source of U.S. EPA guidance for conducting the HHRA is the
Methodology for Assessing Health Risks Associated with Indirect Exposure to
Combustor Emissions, Interim Final (U.S. EPA 1990a).
• In addition, the Addendum to Methodology for Assessing Health Risks Associated
with Indirect Exposure to Combustor Emissions, External Review Draft (U.S. EPA
1993a) that is presently undergoing U.S. EPA revision in response to an external
peer review by the U.S. EPA Science Advisory Board (SAB) is relied upon for the
analysis.
Other recent U.S. EPA guidance that is relied upon to complete this risk assessment
include the Revised Draft Implementation Guidance for Conducting Indirect Exposure
Analysis at RCRA Combustion Units, (U.S. EPA 1994a), the Guidance on Risk
Characterization for Risk Managers and Risk Assessors (U.S. EPA 1992a), the Guidance for
Risk Characterization (U.S. EPA 1995a), and the Guidelines for Exposure Assessment (U.S.
EPA 1992b), which were developed by U.S. EPA to clarify and refocus the requirements for
a complete and balanced risk assessment. For example, the Guidelines for Exposure

Assessment provide a general outline of the possible methods that U.S. EPA recommends
using in an exposure assessment, and identifies important issues concerning presentation of
results (e.g., use of various risk descriptors) and uncertainties.
Additional sources of guidance that are relied upon for the HHRA include: Exposure
Factors Handbook (U.S. EPA 1990b), Dermal Exposure Assessment: Principles and
Applications (U.S. EPA 1992c), Estimating Exposure to Dioxin-Like Compounds, Volume II:
Properties, Sources, Occurrence and Background Exposure, Review Draft (U.S. EPA
1994b), Estimating Exposure to Dioxin-Like Compounds, Volume III: Site-specific Assessment
Procedures, Review Draft (U.S. EPA 1994c), Guidance on Metals and Hydrogen Chloride
Controls from Hazardous Waste Incineration (U.S. EPA 1989a), and other related risk and
exposure assessment guidance documents.
A Project Plan (U.S. EPA 1993b) that describes the proposed methodology used in this
assessment was previously developed and reviewed by an external peer review panel. As
noted earlier, recommendations made by the peer reviewers are incorporated into this
assessment to the extent possible.

m. TOXICITY ASSESSMENT
The toxicity assessment portion of the HHRA combines hazard identification and dose-
response assessment. The primary objectives of this step of the risk assessment process are
to identify the types of toxic effects associated with each substance of potential concern,
characterize the conditions (e.g., route, duration) of exposure under Which these effects
might occur, and determine the relationship between the magnitude of human exposure and
the extent of adverse health effects. This relationship is represented through the use of
toxicity values relating to cancer or noncancer health endpoints.
A. Toxicity Assessment Methods
U.S. EPA has conducted toxicity assessments on many of the most frequently occurring
environmental chemicals and has developed toxicity values for use in risk assessment, based
on these analyses. Cancer and noncancer toxicity values for chemical substances are
published by U.S. EPA and are updated regularly (IRIS 1995; U.S. EPA 1994d). The
Integrated Risk Information System (IRIS) is an on-line data base maintained by U.S. EPA
that provides toxicity data for many commonly detected substances. A second source of
toxicity values is the Health Effects Assessment Summary Tables (HEAST) (U.S. EPA
1994d), which U.S. EPA also updates regularly. The procedures used by U.S. EPA in
evaluating toxicity studies to develop toxicity values are described below.
1. Carcinogenic Effects
Substances classified by U.S. EPA as potentially carcinogenic are considered by
many scientists to pose a finite cancer risk at all exposure levels. In evaluating cancer
risks, therefore, a "no-threshold" assumption is applied. It should be noted that the no-
threshold assumption may not apply for some classes of carcinogens that act through a
mechanism that requires a threshold dose to be exceeded prior to initiation of the
carcinogenic process. For purposes of this assessment, U.S. EPA's no-threshold
assumption is conservatively assumed for all chemical carcinogens.
A two-step evaluation is used in assessing the carcinogenic potential of a chemical.
The first step involves evaluating the likelihood that the substance is a human
carcinogen (i.e., a weight-of-evidence assessment), and the second step involves
defining the quantitative relationship between dose and response (i.e., development of a
External Review Draft
Volume V IE-1 Do Not Cite or Quote
-------
slope factor). In the first step, U.S. EPA classifies a chemical into one of five groups
that indicate the likelihood that the chemical is a human carcinogen, based on the
weight of evidence from human and animal investigations as follows:
• Group A chemicals are classified as human carcinogens;
• Group Bl chemicals are probable human carcinogens with limited human data
available and group B2 chemicals are probable human carcinogens with
sufficient evidence in animals and inadequate or no evidence in humans;
• Group C chemicals are possible human carcinogens; and
• Group D chemicals are not classifiable as to human carcinogenicity.
Those chemicals that are determined to be known, probable, or potential human
carcinogens are further evaluated. The outcome of the second part of the evaluation is
the development of the slope factor (SF), which is a measure of the potency of the
carcinogen. The SF represents the upper 95 percent confidence limit on the linear
component of the slope of the tumorigenic dose-response curve in the low-dose (low-
risk) region. The SF is an upper bound estimate of the likelihood that a response will
occur per unit intake of a chemical over a 70-year lifetime, and is derived by applying a
mathematical model to extrapolate from the relatively high doses administered to
experimental animals or experienced by persons in the workplace to the lower exposure
levels expected for human contact in the environment. A number of low-dose
extrapolation models have been developed; U.S. EPA generally uses the linearized
multistage model hi the absence of adequate information to support some other model.
The linearized multistage model is believed to be conservative, i.e., is likely to
overpredict the true SF for a chemical.
2. Noncarcinogenic Effects
The basic approach used by U.S. EPA in developing toxicity values for
noncarcinogenic effects of substances is based on the belief that some minimum
(threshold) exposure level must be reached before the effect will occur, i.e., that
protective mechanisms exist that must be overcome before an adverse health effect can
occur. The estimated level of daily human exposure below which it is unlikely that
deleterious effects will result is known as the Reference Dose (RfD). RfD values are
reported hi milligrams of chemical per unit body weight per day (mg/kg/d). Unless
adequate human data are available, U.S. EPA develops an RfD value based on data
from experimental animals. If data from several animal studies are available, U.S.
EPA first seeks to identify the animal model that is most biologically relevant to
External Review Draft
Volume V ffl-2 Do Not Cite or Quote
-------
humans (e.g., similar metabolism of the substance). In the absence of information that
r^' """N ' '
( identifies a given animal model as clearly most relevant, U.S. EPA assumes that
humans are at least as sensitive to the substance as the most sensitive animal species
tested. Accordingly, U.S. EPA selects the study using the most sensitive species tested
and the most sensitive endpoint measured as the critical study upon which the RfD is
based (U.S. EPA 1989b).
From this critical study, the experimental exposure representing the highest dose
level tested at which no adverse effects were demonstrated (the no-observed-adverse-
effect level, NOAEL) is identified. In selecting the NOAEL as the basis for the RfD,
the assumption is made that if the critical toxic effect is prevented from occurring, then
all toxic effects are prevented. The NOAEL is to be distinguished from the no-
observed-effect level (NOEL), which corresponds to the exposure level at which no
effect at all is observed; whereas, the NOAEL is the level at which no effect considered
to be of toxicological significance is observed. In some studies, only a lowest-
observed-adverse-effect level (LOAEL) is available. The use of a LOAEL in deriving
an RfD requires the use of an additional uncertainty factor, as described below (U.S.
EPA 1989b).
The RfD is derived from the NOAEL or LOAEL for the critical toxic endpoint by
/ ^ dividing the NOAEL or LOAEL by one or more uncertainty factors. These factors
V> generally are multiples of 10, with each factor representing a specific area of
uncertainty hi the extrapolation from the available study data. For example, a 100-fold
uncertainty factor is typically used when the RfD is based on results from long-term
animal studies. This factor of 100 incorporates an uncertainty factor of 10 to account
for variation hi sensitivity hi the human population and another uncertainty factor of 10
to account for interspecies variability between humans and experimental animals.
Additional modifying factors ranging from 1 to 10 may be applied to reflect qualitative
judgements about limitations or uncertainties hi the critical study or hi the data base as a
whole that are not explicitly addressed by the standard uncertainty factors (U.S. EPA
1989b). Thus, since the RfD is intended to be adequately protective of sensitive
individuals, application of the RfD to the general population is conservative.
Reference Concentration (RfC) values have been developed by U.S. EPA for the
assessment of non-carcinogenic effects from inhalation exposures. RfC values are
reported as air concentrations in units of mass of chemical per unit volume of air (e.g.,
mg/m3). In this assessment, the potential for adverse effects as a result of inhalation
exposure is estimated by comparing exposure concentrations to a fixed fraction of the
RfC. Based on U.S. EPA guidance (U.S. EPA 1989c), a fixed fraction of 25 percent
of the threshold toxicity value (RfC) is allocated for direct inhalation exposure. The
External Review Draft
Volume V m_3 Do Not Cite or Quote
-------
remaining 75 percent of the threshold is allocated to background and other exposures.
This is likely a conservative approach to estimating the potential for noncancer health
effects from inhalation exposure, thus ensuring that such risks are likely not
underestimated. The acceptable concentration calculated in this manner is defined as
the reference air concentration (RAC), which is determined from the inhalation RfC, if
available, or calculated from the oral reference dose (RfD).
For toxic substances for which verified inhalation RfCs are not available, the RAC
is calculated from the oral reference dose (RfD) as recommended hi the incinerator
controls guidance document (U.S. EPA 1989c) and the final rule for boilers and
industrial furnaces (U.S. EPA 1991):
-dayWO kg)[background factor(25%)}
20 m3 air breathed/day
The uncertainty associated with using this route-to-route extrapolation methodology is
discussed hi the uncertainty section of this chapter (Section D).
B. Toxicity Values for Substances of Potential Concern in Stack Emissions
Relevant toxicity values (e.g., RfC, RfD, SF values), compiled (if available) from IRIS,
are presented in Table III-l. Verified toxicity values are not available in IRIS for all
chemicals; therefore, to the extent possible, toxicity values for chemicals of concern without
IRIS toxicity values are compiled from HEAST (U.S. EPA 1994d), consultation with U.S.
EPA, or, in the case of RACs, developed based on route-to-route extrapolation (i.e., use of
an oral RfD for deriving a RAC).
For certain substances or group of compounds, the methodology used to assess toxicity
is somewhat different from that described above. In addition, there are specific issues with
respect to the toxicity of certain substances that should be noted. Therefore, a separate
discussion of the toxicity assessment approach is provided for the following substances: 1)
dioxins and furans; 2) polycyclic aromatic hydrocarbons; 3) lead; 4) mercury; 5) nickel; 6)
chromium; 7) acid gases; and 8) paniculate matter, as discussed below.
1. Dioxins and Furans
There are over 200 individual forms or "congeners" of chlorinated dioxins and
furans. A congener is a single member of a chemical family (e.g., there are 75
congeners of chlorinated dibenzo-p-dioxins). U.S. EPA has developed procedures for
assessing the cancer risks associated with exposure to the many forms of dioxins and
furans based on the relative toxicity of these compounds to the toxicity of 2,3,7,8-
External Review Draft
Volume V ffl-4 Do Not Cite or Quote
-------
tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD), which is generally believed to be the most
( toxic form (U.S. EPA 1994b). Each congener is assigned a value, referred to as a
toxicity equivalency factor (TEF), corresponding to its toxicity relative to 2,3,7,8-
TCDD (i.e., 2,3,7,8-TCDD has a TEF of 1.0 and other dioxin and furan congeners
have TEFs between zero and 1.0). Although various groups and organizations have
developed TEF schemes, the U.S. EPA-recommended approach (U.S. EPA 1994b) is
used in this risk assessment. This approach is the same as the internationally accepted
approach given in the North Atlantic Treaty Organization, Committee on the Challenges
of Modern Society (NATO/CCMS 1988). The TEFs for dioxin and furan congeners
considered in this assessment are presented in Table ffl-2.
Of the 210 possible congeners of the chlorinated dioxins and furans, only the 17
congeners having chlorine substituents hi the 2, 3, 7, and 8 positions are generally
regarded as displaying dioxin-like toxicity (Table III-2). As mentioned above, the
cancer slope factors for dioxin and furan compounds other than 2,3,7,8-TCDD are
derived by the assignment of TEF values which compare the toxicity of the toxic
congeners to that of 2,3,7,8-TCDD. For 2,3,7,8-TCDD, the cancer slope factor is
based on actual experimental evidence in rodents. For the other 16 toxic congeners, the
toxic potency compared to 2,3,7,8-TCDD is based upon receptor binding studies or a
- sensitive measure of receptor binding, namely induction of Aryl Hydrocarbon
\,^' Hydroxylase (AHH) enzyme activity. These TEFs have been developed based upon the
activity of these compounds in short-term toxicity assays that are considered predictive
of their ability to cause cancer in long-term carcinogenicity studies in experimental
animals. Consequently, the cancer slope factors (derived from the TEF values) for
these 16 toxic congeners are less certain than the cancer slope factor for 2,3,7,8-TCDD.
In accordance with U.S. EPA guidance (U.S. EPA 1994b,c), the individual dioxin
and furan congeners are assessed separately throughout the exposure assessment
process. This involves the estimation of congener-specific emission rates, followed by
the evaluation of each congener for partitioning into various environmental media. This
approach is adopted due to the important differences between dioxin and furan
congeners hi the fate and transport properties needed to estimate exposures through the
food chain pathways (U.S. EPA 1994b,c; Washburn 1991; McLachlan 1993). The
TEFs are applied in the final step of the risk assessment process, in estimating potential
health risks.
In addition to the potential for dioxins to cause cancer, there is also concern for
the potential noncancer effects from these chemicals. U.S. EPA concludes that
adequate evidence exists to suggest that exposure to 2,3,7,8-TCDD and related
External Review Draft
Volume V III-5 Do Not Cite or Quote
-------
dioxin-like compounds results in a broad spectrum of effects in animals, some of which
may occur in humans (U.S. EPA 1994h).
This conclusion is based upon results from epidemiology studies in human
populations, experiments in laboratory animals, and ancillary experimental studies. The
effects induced will likely range from adaptive changes at or near background levels of
exposure to adverse effects with increasing severity as exposure levels increase above
background levels. Enzyme induction, alterations hi hormone levels and indicators of
altered cellular function are examples of effects of currently unknown significance; they
may or may not be early indicators of toxic response. Because the threshold levels for
exposure to 2,3,7,8-TCDD and dioxin-like compounds below which toxic effects are not
observed has not been established, the U.S. EPA does not currently list RfD or RfC
values for dioxin-like compounds.
The deduction that humans could respond to exposures to 2,3,7,8-TCDD and
dioxin-like compounds with adverse non-cancer effects is based on the fact that these
compounds impact cellular regulation at a fundamental molecular level in a diverse
variety of animal species which have been shown to respond with adverse effects. In
addition, similar impacts on cellular regulation have been demonstrated hi human cells
hi experimental cell culture.
It is well known that individual animal species vary hi their sensitivity to exhibit
different effects due to exposure to 2,3,7,8-T.CDD. However, the available evidence
indicates that humans most likely fall hi the middle of the range of sensitivity for
individual effects among animals rather than at either extreme. Thus, humans do not
appear to be either extremely sensitive to or extremely insensitive to the individual
effects of 2,3,7,8-TCDD and dioxin-like compounds.
In general, biochemical, cellular and organ-level effects have been observed hi
experiments hi which only 2,3,7,8-TCDD was studied. Specific data on the effects of
other dioxin-like homologues such as the pentachlorinated and hexachlorinated dioxins
and furans are generally not available. However, as mentioned previously, dioxin-like
compounds exhibit the common property of binding to the intracellular Aryl
Hydrocarbon Hydroxylase receptor. Based upon differences hi receptor binding
capacity, toxicity equivalence factors (TEFs) have been developed for the 17 dioxin and
furan congeners with chlorine substituents hi the 2,3,7, and 8 ring positions. The TEF
for 2,3,7,8-TCDD is one; the TEFs for the 16 other congeners are a fraction of this
value (i.e., between zero and 1.0).
Greater uncertainty exists with respect to the extent of non-cancer effects of the 16
other congeners as compared to those of 2,3,7,8-TCDD due to the very limited amount
External Review Draft
Volume V m-6 Do Not Cite or Quote
-------
of toxicology testing of these congeners. Hence greater uncertainty is associated with
the TEFs of these congeners as compared to the TEF for 2,3,7,8-TCDD.
Since formal RfD and RfC values for dioxin-like compounds are not available, it is
not possible to directly quantify in a risk assessment the noncancer effects of exposure
to dioxin-like compounds. However, with regard to incremental exposures to dioxin-
like compounds from point sources such as the WTI incinerator, it is valuable to
compare the estimated incremental exposures to the predicted or expected background
exposure levels.
In this risk assessment, the individual TEF values for each dioxin and furan
congener are applied to the estimated total incremental exposure dose of each congener
for the most highly exposed individual. This results hi the calculation of a toxic
equivalent (TEQ) dose for each congener. The sum of TEQ values for each congener
results hi a total TEQ dose. The total TEQ exposure dose due to operation of the WTI
incinerator is compared to the expected background TEQ exposure dose for individuals
living in the vicinity of WTI, as estimated by U.S. EPA (1994b).
2. Polycyclic Aromatic Hydrocarbons (PAHs)
The compounds benzo[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene,
benzo[k]fluoranthene, chrysene, dibenzo[a,h]anthracene, and indeno[l,2,3-cd]pyrene,
are considered to be carcinogenic by U.S. EPA. With the exception of chrysene, the
PAHs listed above are all known animal carcinogens. U.S. EPA has derived an oral
slope factor of 7.3 (mg/kg-day)'1 (IRIS 1995) for benzofajpyrene (BaP); however, the
remaining carcinogenic PAHs have not been assigned carcinogenic toxicity values in
IRIS because of the limitations of the cancer studies performed on these compounds.
Until individual toxicity values are assigned, U.S. EPA (1993c) recommends an
interim relative potency approach to determining carcinogenic potential based upon
results in a group of carcinogenicity studies in animals. The toxicity of each
carcinogenic PAH is evaluated relative to the toxicity of BaP. The potency of BaP has
been assigned a value of 1.0, which is equivalent to an oral slope factor of 7.3 (mg/kg-
day)"1, and other PAHs have relative potencies between zero and one, as shown hi Table
III-3. Each of the PAHs considered in this assessment are evaluated separately with
regard to estimating stack emissions, modeling fate and transport in the environment,
and quantifying human dose. The relative potency factors hi Table III-3 are applied in
the final step of the risk assessment process, in estimating potential health risks.

3. Lead
U.S. EPA does not currently list an RfD or RfC for lead because a threshold level
for exposure to lead below which toxic effects are not observed has not been
established. Additionally, based upon findings that neurobehavioral effects have been
observed in children with blood lead levels below those that have caused carcinogenic
effects in laboratory animals, a cancer SF has not be derived by U.S. EPA. The
Agency has relied upon the neurological effects observed in children as the sensitive
endpoint for evaluating lead toxicity. Consequently, U.S. EPA has applied an
uptake/biokinetic modeling approach, which evaluates potential risks by predicting
blood lead levels associated with exposure to lead. The uptake/biokinetic model (U/BK)
for lead was developed through the efforts of U.S. EPA (1990c) and New York
University professors N.H. Harley and T.J. Kneip (Kneip et al. 1983). It integrates a
number of assumptions about the complex exposure pattern and physiological handling
of lead by the body, and has been validated at several sites where lead exposure data
and human blood lead levels are available (U.S. EPA 1990c). The U/BK model has
been reviewed and recommended by the U.S. EPA Science Advisory Board (SAB)
(U.S. EPA 1992d).
U.S. EPA has developed a computerized version of the U/BK model (version
0.99d) that predicts blood lead levels and distributions for children ages zero to seven
years of age (U.S. EPA 1994e). At present, as directed by U.S. EPA (1994e), it is not
possible to apply the computer model to predict potential blood lead levels in adults. In
general, however, children are more susceptible to lead exposures than adults as a result
of higher soil ingestion rates and greater absorption from the gut, in addition to
nutritional variables and lower body weight. Thus, in this assessment, environmental
concentrations of lead resulting from stack emissions are used, with the U/BK model, to
predict the child blood lead levels.
4. Mercury
Mercury can exist in either organic or inorganic forms in the environment.
Although emissions from the stack at the WTI facility are expected to be in an inorganic
form (as metallic mercury), it is possible that some portion of the mercury is converted
to organic forms (e.g., methylmercury) in the environment. The bioaccumulation
potential of methylmercury may be as much as ten times greater than that of inorganic
forms of mercury. Based on recommendations by U.S. EPA in its Report to Congress
on mercury in the environment (U.S. EPA 1994f), it is assumed that 25 percent of the
mercury in aquatic environments is in the organic form. Mercury in air, soil,

-------
vegetation, and animal products (with the exception of fish) is assumed to be entirely
inorganic.
5. Nickel
U.S. EPA treats certain forms of nickel, including nickel carbonyl, nickel
subsulfide, and nickel refinery dust, as carcinogens. However, U.S. EPA, in the Final
Rule for Burning of Hazardous Wastes in Boilers and Industrial Furnaces (U.S. EPA
1991), does not consider nickel emissions from hazardous waste combustions units to be
carcinogenic because the carcinogenic forms of nickel are not expected to be present in
the oxidizing environment of combustion units. More recent data, however, suggest
other forms of nickel may be carcinogenic, and the International Agency for Research
on Cancer (IARC) has classified "nickel and certain nickel compounds" as probable
human, inhalation carcinogens. Therefore, to ensure that the potential inhalation cancer
risks associated with inhalation exposure to airborne nickel are not underestimated, this
assessment evaluates nickel as an inhalation carcinogen.
6. Chromium
The oxidation state of chromium is a crucial issue in evaluating the toxicity of this
metal and the risks associated with exposure. Hexavalent chromium (Cr+6) is the most
toxic valence state of chromium and has been shown to be a human carcinogen through
inhalation exposure. Trivalent chromium, a commonly found less oxidized form of
chromium, has not been shown to be carcinogenic in either humans or laboratory
animals. U.S. EPA (1990d,e) has indicated that chromium emitted from a combustion
unit is not likely to be hi the hexavalent form; however, sufficient evidence does not
exist to reliably estimate the partitioning of chromium emissions into these two valence
states. Therefore, the worst-case assumption that 100 percent of the facility chromium
emissions are in the hexavalent form is adopted.
7. Acid Gases
Exposure to acid gases may occur through the inhalation pathway. However, there
are currently no U.S. EPA-verified inhalation toxicity values (e.g., RfC or SF values)
for sulfur oxides or nitrogen oxides. Therefore, estimated ah" concentrations of these
acid gases are compared in this assessment to the National Ambient Air Quality
Standards (NAAQS), which were developed by U.S. EPA to be protective of human
health. The NAAQS for sulfur dioxide and nitrogen dioxide are 100 /*g/m3 and 80
jiig/m3, respectively (40 CFR 50.4-50.12).

8. Paniculate Matter
There are currently no RfD, RfC, or SF values for either total particles or
respirable particles (generally assumed to be particles with an aerodynamic diameter
equal to or less than 10 micrometers, or PM10). In this assessment, estimated air
concentrations of paniculate matter are compared to the NAAQS. The annual average
NAAQS for PM10 is 50 pg/m3 (40 CFR 50.4-50.12).
C. Toxicity Assessment for Substances of Potential Concern in Fugitive Emissions
Although the general methodology for assessing the toxicity of chemicals emitted from
fugitive sources does not differ from the methodology used for substances emitted from the
stack, a different list of chemicals may apply to emissions from fugitive sources. As noted
previously, fugitive emissions occur from two types of sources resulting in two different
types of substances: volatile organic compounds (from four specific sources) and metals (in
ash).
1. Fugitive Organic Chemical Emissions
Given their volatile nature, exposure to fugitive vapor emissions is expected to
occur primarily through inhalation. Therefore, the relevant inhalation toxicity values
(e.g., RAC, inhalation SF) are compiled from IRIS (1995) and HEAST (U.S. EPA
1994d), and are presented in Table III-4. As indicated in Table III-4, for the chemicals
with potential noncancer health effects, RACs are developed from the RfCs or from oral
RfDs, based on a route-to-route extrapolation, as described earlier.
2. Fugitive Ash Emissions
The evaluation of risks associated with fugitive ash emissions is conducted for
exposure by inhalation and by indirect exposure pathways. The relevant inhalation and
oral toxicity values for the substances identified hi ash samples from the WTI facility
are summarized in Table III-5.
D. Uncertainties
In the majority of risk assessments, as hi this risk assessment, available scientific
information is insufficient to provide a complete understanding of all the toxic properties of
chemicals to which humans are potentially exposed. It is generally necessary, therefore, to
infer these properties by extrapolating them from data obtained under other conditions of
exposure, frequently hi laboratory animals. In evaluating the toxicity of the substances
considered hi this assessment, a number of assumptions are made. Table III-6 summarizes
the key assumptions used in this chapter. In addition to noting the key assumptions, Table

III-6 provides the basis for each assumption, and the direction and relative magnitude of the
I effect of each assumption on the overall estimated risks, as discussed in Volume II.
^___x'
Experimental animal data have been relied upon for many years by regulatory agencies
and other expert groups for assessing the hazards and safety of human exposure to chemicals.
This reliance has been supported in general by empirical observations. There may be
differences hi chemical absorption, metabolism, excretion, and toxic response, however,
between humans and the species for which experimental toxicity data are generally available.
Uncertainties associated with the characterization of chemical toxicity hi humans are also
introduced as a result of the following (U.S. EPA 1989b):
• Using dose-response information from effects observed at relatively high exposure
levels to predict effects that may occur following exposure to the much lower
exposure levels expected from contact with the chemical in the environment;
• Using data from dne route of exposure to predict effects from exposure via other
routes;
• Using dose-response data from short-term or subchronic exposures to predict the
/ \ effects following longer-term exposure; and
V,y
• Using dose-response information from homogeneous animal populations or healthy
human populations to predict effects that may occur hi the general population,
including sensitive subpopulations.
The methods, for addressing these uncertainties in the toxicological assessment for
noncarcinogens and carcinogens are discussed below.
1. Uncertainties in the Characterization of the Toxicity of Carcinogens
For many substances that are carcinogenic hi animals, there is uncertainty as to
whether they are also carcinogenic in humans. The Office of Science and Technology
Policy (OSTP 1985) has observed the following:
"...known human carcinogens, with the single exception of arsenic, are
carcinogenic in appropriately conducted studies hi some animal system
(arsenic has recently been reported to produce carcinomas of the
respiratory tract in hamsters). This does not mean that all chemicals
/"^•.
( found carcinogenic in annuals will turn out to be carcinogenic hi

-------
humans. Because of differences in the production of critical metabolites
and because of other differences between species, a given carcinogen
may not produce cancer in all species or in all strains of rodents."
The finding that relatively few substances are known human carcinogens may be
due in part to the difficulty in conducting adequately designed epidemiologic
investigations in exposed human populations. The available data in humans are derived
mainly from retrospective epidemiology studies of workers exposed to multiple
chemicals and at doses that can not be reliably quantified.
As with RfD and RfC values, all U.S. EPA-verified slope factors in IRIS are
accompanied by a weight-of-evidence classification, which is an indication of the
likelihood that the agent is a human carcinogen. This classification is based on the
completeness of the evidence that the agent causes cancer in experimental animals and
humans. The strength of the evidence that a carcinogen is a potential human carcinogen
is strengthened by such factors as the following: (1) greater number of tissue sites
affected by the agent; (2) carcinogenic response in more than one species, strain, and
sex, and by multiple routes of exposure; (3) evidence of a clear-cut dose-response
relationship as well as a high level of statistical significance of the increased tumor
incidence in treated compared to control groups; (4) dose-related shortening of the time-
to-tumor occurrence or time to death with tumor; (5) dose-related increase in the
proportion of tumors that are malignant; (6) a plausible biological mechanism of
tumorigenicity; (7) similar carcinogenic properties exhibited by structurally-related
compounds; (8) evidence of an association between exposure to the chemical of concern
and an increased tumor incidence in human populations (U.S. EPA 1989b; U.S. EPA
1986a).
Because of uncertainties associated with the measure of carcinogenic potency of a
chemical in humans, U.S. EPA has adopted procedures hi the calculation of slope
factors that are generally conservative. For example, hi the absence of data to the
contrary, U.S. EPA uses the biologically acceptable data set from long-term animal
studies showing the greatest sensitivity (U.S. EPA 1986a).
There are several mathematical models available to derive low-dose unit risks from
high exposure levels used in experimental studies. No single model is recognized as the
most appropriate for low-dose extrapolation. The model generally used by U.S. EPA is
the linearized multistage model, which generally provides the most conservative
estimate of risk at low doses (i.e., highest risk per unit dose). The procedure employed
by U.S. EPA is also to use the 95 percent upper confidence limit on the slope of the
dose-response curve estimated by the linearized multistage model. According to U.S.
External Review Draft
Volume V m-12 . Do Not Cite or Quote
-------
EPA (1989b), use of the 95 percent upper confidence limit value, rather than the unit
risk that represents the maximum likelihood estimate, provides an estimate of the upper
boundary on risk. U.S. EPA (1986a) has also emphasized "that the linearized
multistage model leads to a plausible upper limit to the risk that is consistent with some
proposed mechanisms of carcinogenesis. Such an estimate, however, does not
necessarily give a realistic prediction of the risk. The true value of the risk is
unknown, and may be as low as zero."
2. Uncertainties in the Characterization of the Toxicity of Noncarcinogens
To adjust for uncertainties such as those discussed above, U.S. EPA and other
regulatory agencies typically base the RfD or RfC (or other expression of the acceptable
daily intake) for noncarcinogens on the most sensitive animal species, i.e., the species
that experiences adverse effects at the lowest dose. This dose is then adjusted by the
use of uncertainty and modifying factors to compensate for various sources of
uncertainty in the underlying toxicity data. The resulting toxicity factor incorporates a
substantial margin of safety, although the actual size of this safety margin cannot be
quantified with any certainty.
For all verified RfD and RfCs, U.S. EPA does provide in IRIS a qualitative
statement of the confidence that the evaluators have in the RfD or RfC itself, in the
critical study upon which the RfD or RfC is based, and in the overall data base.
U.S. EPA guidance for hazardous waste incinerators (U.S. EPA 1989a) suggests
that where a verified oral RfD has been developed by U.S. EPA but where there is no
verified RfC for that substance, the RfD should be used to extrapolate to the inhalation
RAC. As noted by U.S. EPA (1989a), certain limitations are introduced with such
route-to-route extrapolation with respect to: "(a) the appropriateness of extrapolating
when a portal of entry is the critical target organ; (b) first pass effects; and (c) the
effect of the route upon dosimetry." The compounds for which this process is used to
determine RACs are noted in Tables III-l, III-4, and III-5.
In general, it is expected that these assumptions will result in an overestimation of
the toxicity of chemicals with noncarcinogenic effects.
3. Uncertainties Associated with Endocrine Disrupters
The term "endocrine disrupters" (sometimes referred to as "environmental
hormones") applies to any number of a broad class of chemical compounds with the
ability to perturb or interfere with the finely-tuned endocrine system that is fundamental
to normal function and homeostasis hi cells, tissues and organisms. The current
concern about endocrine disrupters stems from a body of diverse historical information
External Review Draft
Volume V m-13 Do Not Cite or Quote
-------
and more recent findings which have been integrated into a working hypothesis. The
central theme of the hypothesis is that exposure to exogenous hormone-mimetic agents
that interfere with the production, release, transport, metabolism, receptor binding,
action or elimination of natural blood borne hormones and ligands can potentially lead
to adverse health effects, particularly effects on reproduction function.
The data that have contributed to this working hypothesis stem from a number of
different disciplines. These include wildlife reproduction (feminization of birds,
alligators, and certain terrestrial mammals); wildlife population ecology (population
declines); human reproductive physiology (decreased sperm count in males hi
industrialized nations); epidemiology (observed increases in breast cancer in
industrialized nations); molecular biology (receptor-mediated mode of action data); and
endocrinology (increased understanding of mechanisms of hormone regulation and
impacts of perturbations). These findings serve as a basis for further experimentation to
determine whether the fundamental hypothesis is correct, and, if so, to what extent.
The broad definition of chemicals which could qualify as endocrine disrupters is
particularly problematic for the process of risk assessment. These problems include the
following: 1) reliance on limited, and in some cases conflicting, empirical data to
support the designation of specific chemicals as endocrine disrupters; 2) lack of a clear
structure-activity relationship among the diverse group of chemicals considered to be
endocrine disrupters; 3) lack of unifying dose-response relationships among the diverse
group of chemicals; and 4) existence of multiple modes of action for chemicals
currently considered to be endocrine disrupters.
Given the current limited state-of-the-science, it is premature to attempt to evaluate
the potential risks from human exposure to chemicals from the standpoint of endocrine
disruption. Therefore, the U.S. EPA has not yet developed a methodology for the
quantitative assessment of risks due to exposures to potential endocrine disrupters.

TABLE III-6
Key Assumptions for Chapter III
(Toxicity Assessment)
Assumption
The following assumptions are implied in using EPA
toxicity values in the assessment:
The chemical toxicity values in IRIS and HEAST
are accurate
A "no-threshold" assumption has been applied for
exposure to carcinogens
The SF is based on the upper 95 % confidence
limit based on the linearized multistage model
A "threshold" assumption has been applied for
exposure to chemicals with non-carcinogenic
affects
The RfD is related to the NOAEL or LOAEL by
uncertainty factors
Oral values apply for dermal exposures
RACs are developed from oral RfDs when RfCs are not
available
Nickel is evaluated for both carcinogenic and
noncarcinogenic effects
Dioxin-like compounds are assigned cancer slope factors
based on the TEF scheme
The cancer slope factors of PAHs are assigned based on a
relative potency scheme
Basis
Toxicity values presented in IRIS and HEAST reflect
EPA's conservative assessment of the available data
and include safety factors as appropriate.
It is conservative to assume that oral data apply
when there is a lack of data for the inhalation route.
A conservative assumption because there is no direct
evidence that the forms of nickel expected to be
emitted from hazardous waste combustion units are
carcinogenic. IARC and U.S. EPA, however, both
recognize that certain forms of nickel could be
carcinogenic by the inhalation route.
The internationally accepted approach is used in this
assessment.

IV. SELECTION OF SURROGATE CHEMICALS
A. Selection of Chemicals in Stack Emissions to Evaluate in the Risk Assessment
As identified in the preceding chapters, almost 200 organic compounds are identified
that could potentially be released from the incinerator stack. Human health risks associated
with direct inhalation of each of these compounds are quantitatively evaluated in the HHRA.
In order to focus the assessment of risks from indirect pathways of exposure, a subset of the
organic compounds listed in Table 1-1 is selected that are predicted to contribute most of the
risks. This subset of compounds, referred to as the "surrogate organic chemicals", is the
subject of further quantitative evaluation.
In assessing the risks associated with indirect exposure to organic compounds emitted
from the stack, the selection of surrogate chemicals focuses on the organic residues and PICs
that are highly toxic and have the greatest potential to accumulate in environmental media.
Surrogate organic chemicals are selected based on the following factors:
Emission Rate - as reflected by data collected during trial burns and performance tests
at the WTI facility, as estimated earlier;
Toxicity - considering both carcinogenic and noncarcinogenic effects; and
Bioaccumulation Potential - based on the octanol/water partition coefficient, K^, a
measure of a chemical's likelihood to bioaccumulate.
The surrogate chemicals selection process consists of two steps and is in general
agreement with the most recent U.S. EPA guidance for conducting risk assessments at RCRA
hazardous waste combustion units (U.S. EPA 1994a), with the following deviation. K^, is
used hi the selection process instead of log K^ to be consistent with the bioaccumulation
equations in the fate and transport modeling. The use of K^ will lead to the selection of
chemicals that are the most likely to bioaccumulate, and therefore, present the greatest
significance hi the indirect risk assessment. Chemicals that are selected by this approach
may be further evaluated for then- persistence and bioaccumulation potential in environmental
media and the food chain. The factors to be evaluated would include the potential for

-------
biodegradation, absorption, metabolism, and excretion. The following steps outline the
methodology used in the surrogate chemical selection process.
Step 1: Selection of Surrogates on the Basis of Quantity, Carcinogenic Potency,
and Bioaccumulation Potential
In Step 1, 17 dioxin and furan congeners and 174 organic residues and PICs are
ranked on the basis of estimated quantity emitted, carcinogenic potency, and
bioaccumulation potential, as determined by the following equation:
QCB = (ERXSFXK™) (IV-1)
where:
QCB = quantity/carcinogenic potency/bioaccumulation potential score
ER = estimated emission rate
SF = slope factor (oral or inhalation, whichever is higher [to be
conservative])
K,,w = octanol-water partition coefficient, which is related to a chemical's
bioaccumulation potential in milk, meat, and fish.
Average emission rates in the above equation for the dioxin and furan congeners
and PICs are estimated as described hi Volume ffl. Emission rates are not available for
31 compounds; consequently, these compounds are not evaluated in this assessment.
Chemical-specific values for the octanol-water partition coefficient, K,,,,, used in
the above equation are obtained from the literature. K^ values reported in the scientific
literature often vary (sometimes by more than an order of magnitude) from one source
to another, depending on the methodology used to derive the value. Therefore, the
selection of K<,w values used in calculating QCB scores is conducted using the following
sources. For the dioxin and furan congeners and chlorinated biphenyls, KOW values are
obtained from the report, Estimating Exposure to Dioxin-Like Compounds (U.S. EPA
1994b). For the PICs, the U.S. EPA document titled: Internal Report on Summary of
Measured, Calculated and Recommended Log K^ Values (U.S. EPA 1995b) is used as
the primary source of K^, values. The K^ values recommended hi this document are
used hi the HHRA. K^ values are not available hi this source for 29 compounds, so
other sources are relied upon, including Howard (1993), the National Library of
Medicine's Hazardous Substance Data Bank (HSDB), U.S. EPA (1990f), Verschueren
(1983), and Montgomery and Welkom (1990). For chemicals that have multiple K,,w

-------
values listed in these sources, the maximum value is conservatively applied in this
assessment. It should be noted that a K^ value could not be found hi the literature for
dibenzo(a,h)fluoranthene. This chemical, therefore, is not evaluated in this assessment.
The log K^ values used in this assessment are presented in Appendix V-l.
Slope factors, obtained from the U.S. EPA Integrated Risk Information System
(IRIS) and HEAST (U.S. EPA 1994d) data bases, are listed hi Table ni-1. Chemicals
for which slope factors are not available from these sources are not considered in this
step. Of the chemicals considered, slope factors are not available for 77 compounds
(the absence of slope factors indicates that these compounds have not exhibited
carcinogenic effects in toxicity studies or not enough data were available for U.S. EPA
to derive cancer toxicity values). These compounds may have noncarcinogenic effects
and are included hi Step 2. A tabulation of the emission rates, slope factors, and K,,w
values used hi estimating QCB scores is presented hi Appendix V-2. (Appendix V-2
does not include the 31 compounds for which emission rates are not available.)
The 65 PICs and 17 dioxins/furans for which slope factors were available are
ranked on the basis of QCB score and 8 surrogate organic compounds (plus 17
dioxin/furan congeners) are selected for evaluation hi the HHRA. As can be seen from
Table IV-1, which shows the chemicals with the highest QCB scores, the dioxin and
furan congeners account for approximately 95% of the total QCB score. Additionally,
the 17 dioxin and furan congeners and 8 organic PICs that are retained by the screen
incorporate approximately 99.8% of the total QCB score. The cutoff criterion is
selected to ensure all the dioxin and furan congeners are included. It should be noted,
however, that of the eight surrogate organic compounds selected, only one, bis(2-
ethylhexyl)phthalate, was detected during the August 1994 PIC testing.
In addition to the compounds selected on the basis of the QCB score, two PCBs,
tetrachlorobiphenyl and hexachlorobiphenyl, are included for quantitative evaluation in
the HHRA to represent PCB compounds that have high bioaccumulation potential.
Step 2: Selection of Surrogates on the Basis of Quantity, Noncarcinogenic
Toxicity, and Bioaccumulation Potential
In Step 2, organic chemicals are ranked on the basis of quantity, noncarcinogenic
toxicity, and bioaccumulation potential, as determined using the following equation:
QNB = (ER)(Kow)/RfD (IV-2)
External Review Draft
Volume V rV-3 Do Not Cite or Quote
-------
where:
QNB = quantity/non-cancer toxicity/bioaccumulation potential score
ER = emission rate
K^ = octanol-water partition coefficient, which is related to a chemical's
bioaccumulation potential hi milk, meat, and fish
RfD = reference dose (oral or inhalation, whichever is smaller to be
conservative).
RfD values, obtained from IRIS and HEAST (U.S. EPA 1994d) data bases, are
listed hi Table III-l and in Appendix V-2. The 72 chemicals (this includes the 17
dioxins/furans) for which RfD values are not available are not included in this step.
Emission rates and K^ values are estimated using the methods described earlier.
The results of Step 2 for the 87 chemicals with RfD values are presented in Table
I V-2. A cutoff of 99% of the total QNB score is used, resulting hi five chemicals
being retained on the basis of emission rate, toxicity, and bioaccumulation potential.
With the exception of bis(2-ethylhexyl)phthalate, none of the surrogate chemicals
selected on the basis of QNB score were detected hi the August 1994 PIC testing at the
WTI facility.
Carbon tetrachloride is also retained for evaluation hi the HHRA since it is the
next highest ranked compound (based on QNB score) that was actually detected hi the
August 1994 PIC testing. Table IV-3 contains a listing of all chemicals to be evaluated
hi the indirect risk assessment.
In summary, 8 surrogate organic compounds and 17 dioxin/furan congeners are selected
for evaluation on the basis of QCB score. Two PCBs (tetrachlorobiphenyl and
heptachlorobiphenyl) are selected on the basis of bioaccumulation potential. Five chemicals
are selected on the basis of QNB score [bis(2-ethylhexyl)phthalate appears on both the QCB
and QNB lists]. In addition, carbon tetrachloride is added to the QNB list to provide another
chemical that was actually detected in PIC testing. The list of surrogate organic compounds
evaluated hi the HHRA is shown hi Table IV-3. All of the metals for which toxicity data are
available (see Table ni-1) are included in Table IV-3. Appendix V-2 provides a list of the
organic compounds (142 organic compounds and 17 dioxins/furans) considered hi the
assessment for which emission rates or K,,w values are available. The emission rates, slope
factors, reference doses, and octanol-water coefficients used hi calculating the QCB and QNB
scores are also presented hi Appendix V-2.
It should be noted that once a surrogate organic chemical is selected, it is evaluated hi
the HHRA for both cancer and noncancer toxicity, regardless of the basis of its selection

(i.e., chemicals selected on the basis of carcinogenic potential are also evaluated for
/•- ""•>
' noncancer effects, if noncancer toxicity values are available. Similarly, chemicals selected
on the basis of noncancer toxicity are also evaluated for carcinogenic potential, if cancer
toxicity values are available).
B. Partitioning of Emissions Between the Vapor and Particle Phases
As discussed in Volume ffl, stack gas from the WTI incinerator contains substances
present hi either the vapor phase or as particles. When the stack gas is emitted to the
atmosphere, vapor-phase substances will either remain hi the vapor phase or adsorb onto
particles present hi the gas stream. The methodology for predicting this partitioning is
described hi Volume III. This methodology is applied to the dioxin/furan compounds, the
surrogate organic chemicals selected hi the previous sections of this chapter, and mercury.
The fraction of organic chemicals that adsorbs to particles is estimated using the
equations hi Volume III and is presented hi Table IV-4 for the dioxin and furan congeners,

C. Selection of Chemicals to Evaluate in Fugitive Emissions Analysis
Residents hi the immediate vicinity of the WTI facility may be exposed to fugitive
emissions of volatile organic compounds from the site. Fugitive chemicals are primarily
volatile constituents present hi the waste feed that are released during waste handling and
processing prior to incineration. These volatile constituents are released from locations close
to ground elevation and are likely to have a more localized impact than chemicals emitted
from the stack. Consequently, the surrogate selection procedure for fugitive emissions is
directed towards identifying chemicals present hi the waste feed that are of concern as a
result of direct inhalation exposures.
Following the selection of the surrogate fugitive organic chemicals for analysis,
chemical-specific emission rates are estimated, based on the physical-chemical properties of
the surrogate chemicals.
1. Selection of Surrogate Chemicals in Fugitive Vapor Emissions
More than 300 organic compounds are identified as being hi the pumpable feed at
the facility, likely to be the most significant source of fugitive emissions from the WTI
i facility. To focus the risk assessment of fugitive organic vapor emissions, a subset of

these compounds, referred to as surrogate chemicals, is developed. The selection of
surrogate chemicals that significantly contribute to health risks associated with fugitive
organic vapor emissions from the WTI facility is based on the quantity, volatility, and
toxicity of the chemicals as follows:
Quantity - quantity is accounted for by estimating the total moles of each chemical
that are processed by WTI, based on the total pounds annually in the pumpable
feeds at the facility and the molecular weight of the chemicals;
Volatility - volatility of each compound is accounted for by its vapor pressure,
which reflects the equilibrium of the chemical between the vapor and condensed
(i.e., generally liquid) phases at a specific temperature (25°C assumed); and
Toxicity - toxicity is evaluated using cancer slope factors (SFs) and noncancer
reference doses (RfDs) that have been compiled by U.S. EPA. When available,
SFs and RfDs for the inhalation route of exposure are used; however, for many
chemicals only oral toxicity values are available, and these are conservatively
applied. Oral toxicity values are used to estimate inhalation toxicity for 28
chemicals with non-cancer chronic toxicities.
To facilitate the surrogate selection process, the original list of approximately 300
chemicals identified in the pumpable waste feed is condensed to a list of 96 chemicals
that account for 90 percent of the total pumpable feed processed hi a year, as presented
in Appendix V-4. These 96 compounds are evaluated using the following methodology.
Step 1: Selection of Chemicals Based on Quantity, Vapor Pressure, and
Carcinogenic Potency
The 96 compounds are scored and ranked on the basis of quantity, vapor pressure,
and carcinogenic potency using the following equation:
SCC = (FR/MW)(SF)(VP) (IV-3)
where:
SCC = surrogate chemical score for carcinogens
FR = feed rate
MW = molecular weight
External Review Draft
Volume V IV-6 Do Not Cite or Quote
-------
SF = inhalation slope factor
VP = vapor pressure
Feed rates for individual waste stream constituents are estimated based on waste
quantities projected for the first year of operation of the WTI facility, as described in
Appendix m-1. Slope factors are obtained from IRIS (1995) and HEAST (U.S. EPA
1994d). Nineteen of the 96 compounds have slope factors. Chemicals for which SFs
are not available are not included in this step, but are included in Step 2. Vapor
pressures and molecular weights are obtained from several sources, including Howard
(1993), the National Library of Medicine's Hazardous Substance Data Bank (HSDB),
Montgomery and Welkom (1990), and the Kirk-Othmer Encyclopedia of Chemical
Technology (Grayson 1984).
Four surrogate chemicals, which are listed in Table IV-5, are selected on the basis
of the SCC score. These compounds are selected so as to account for at least 90 percent
of the total surrogate chemical score for carcinogens, as indicated in Table IV-5.
Step 2: Selection of Chemicals Based on Quantity, Vapor Pressure, and
Noncancer Toricity
The 96 compounds are scored and ranked on the basis of quantity, vapor pressure,
and the potential to cause noncarcinogenic health effects using the following equation:
SCNC = (FR/MW)(VP)/(RAC) (IV-4)
where:
SCNC = surrogate chemical score for chemicals with non-cancer chronic
toxicities
FR = feed rate
MW = molecular weight
RAC = reference air concentration
VP = vapor pressure
Feed rates, vapor pressures, and molecular weights for individual waste stream
constituents are estimated, using the methods described earlier. Inhalation and oral
reference doses, to estimate RACs, are obtained from IRIS and HEAST (U.S. EPA
1994d); values were available for 51 chemicals. Chemicals for which RfDs are not
available are not included in this step.

Nine surrogate chemicals (two of which were selected in the previous step as
carcinogens), which are listed hi Table IV-6, are selected on the basis of the SCNC
score. These compounds are selected so as to account for at least 90 percent of the
total surrogate chemical score for chemicals with non-cancer chronic toxicities, as
indicated in Table IV-6. In total, 11 chemicals are identified as surrogates for the
quantitative evaluation of fugitive emissions, as listed in Table IV-7.
Appendix V-4 provides a list of the 96 organic compounds considered, vapor
pressures, slope factors, reference doses, and feed rates used in calculating SCC and
SCNC scores.
2. Estimation of Chemical-Specific Fugitive Organic Vapor Emission Rates
Total fugitive emission rates are estimated in Volume ffl for four organic vapor
sources based on fugitive emissions models, waste feed throughput, and U.S. EPA-
derived emission factors, as summarized hi Table FV-8. Chemical-specific emission
rates from one of these sources, tanks hi the tank farm that are vented to the CAB
system, are estimated using U.S. EPA's tank calculation program known as TANKS2.
The TANKS2 program uses parameters such as molecular weight, vapor pressure over
a range of temperatures, and chemical-specific feed rates to derive emission rates. The
program requires chemical-specific information on the 11 surrogate chemicals, as well
as data on the physical properties of the remainder of the waste feed. To represent the
remainder of the waste feed, it is assumed to be primarily composed of the 12
constituents present in the highest volume, as determined from the waste profile for the
first year of operation1. The waste feed throughput to these tanks is based on the
maximum heat input rate based on the design of the incinerator (121 million BTU/hr
higher heating value [HHV]; ENSR 1993). The resulting total tank farm-related
emissions from the CAB system are estimated to be 212.2 Ibs/year, as shown in Table
IV-8. The TANKS2 program also provided an estimate of the emissions represented by
each of the surrogate organic chemicals, as summarized hi Table IV-9. It should be
noted that the vapor pressure for dichlorodifluoromethane is beyond the acceptable
range permitted by the TANKS2 program, so an emission rate is not developed for this
compound. However, as evident from the SCNC score for dichlorodifluoromethane
(Table IV-6), this compound is estimated to consititute only approximately eight percent
of the fugitive risk associated with the compounds with noncancer effects.
1 Waste feed properties are assumed to be reflective of the 12 constituents that comprise
approximately 60 percent of the waste feed. The surrogate chemical emission rates are not
expected to be very sensitive to the overall waste feed properties.

-------
The results of the tank farm modeling are extrapolated to the other emission
sources by assuming that the chemical composition of fugitive emissions (expressed as a
weight fraction) will be the same for all the identified fugitive emission sources. Thus,
weight fractions of individual constituents derived from the above analysis of tank farm
emissions are used with estimates of total fugitive emission rates (Table FV-8) for each
of the sources of fugitive organic emissions in determining chemical-specific emission
rates. Weight fractions in the vapor phase for each of the surrogate chemicals are
determined using the chemical-specific emission rates summarized hi Table IV-9 and the
total predicted tank farm-related emission rate of 212.2 Ibs/yr, and are summarized hi
Table IV-10.
The chemical-specific fractions in Table IV-10 are multiplied individually by the
total estimated emission rates for each of the fugitive organic vapor emissions sources
identified in Table IV-8. Thus, chemical-specific emission rates for each of the four
sources are estimated and are summarized hi Table IV-11. It should be noted that since
the waste water tank contains highly diluted wastes, use of this procedure of deriving
chemical-specific emission rates will significantly overstate actual emissions from the
waste water tanks. Total fugitive emissions, however, should not be significantly
overestimated because fugitive emissions from the waste water tank account for only a
small fraction (less than 10 percent) of the total fugitive emissions from the facility.
3. Estimation of Chemical-Specific Emission Rates in Fugitive Ash
Emissions of specific metals contained within the fugitive ash are estimated based
on the available data on ash composition. In 1994, WTI conducted monthly sampling
of ash from the ESP. The samples of fly ash were analyzed by WTI for 80 volatile and
semi-volatile organic compounds, total and amenable cyanide, and 9 metals. None of
the 12 samples indicated detectable levels of any of the 80 organic compounds. Organic
compounds, therefore, are not evaluated further in the analysis of fly ash emissions.
Average metal concentrations associated with the fly ash are estimated based on
the monthly sampling results, shown hi Table IV-12. In estimating average
concentrations, it is assumed that metals that were detected on at least one occasion are
present in the ash at one-half the detection limit on other occasions when the
concentrations are reported to be below the detection limits.
To estimate metal-specific emission rates, the concentration of each metal (or
inorganic analyte hi the case of total cyanide) is multiplied by the estimated fugitive ash
emission rate of 4.03 x 10"* g/sec (estimated hi Volume III). The resulting metal-
specific emission rates due to fugitive ash releases are summarized hi Table IV-12.

D. Uncertainties
In selecting chemicals for quantitative evaluation, it is possible that some are eliminated
from consideration (e.g., because of a lack of toxicity values) that may pose a potential
health risk. The process described in this chapter was developed to reduce the uncertainty
associated with this step. However, there are several key assumptions, which are shown in
Table IV-13, that may affect the outcome of this assessment. Most importantly, the selection
of K<,w values from the range of values reported in the literature could have a significant
impact on whether a chemical is selected as a surrogate. In this assessment, a conservative
method is used in selecting K^ values; therefore, as indicated hi Table IV-13, it is possible
that an overestimate of risks (associated with organic compounds) may result.
The following sections provide a qualitative summary of the uncertainties associated
with the methodologies discussed 'm this chapter.
1. Uncertainties Associated with the Selection of Surrogate Organic Chemicals in
Stack and Fugitive Emissions
There are some uncertainties introduced hi condensing the hundreds of chemicals
present in emissions from the facility to a smaller list of surrogate chemicals that are
quantitatively evaluated. However, the scoring procedure used to select surrogate
chemicals is designed to provide reasonable estimates of the relative risk posed by the
individual chemicals, which ensures that a significant percentage of the risk is accounted
for by the surrogate chemicals. For example, the surrogate chemicals emitted from the
stack account for greater than 99 percent of the total stack score; the surrogate
chemicals for fugitive emissions account for approximately 90 percent of the total
fugitive score. Thus, the estimated risks are not anticipated to be significantly
understated by selecting a subset of the chemicals emitted for quantitative evaluation.
2. Uncertainties Associated with Estimating Chemical-Specific Fugitive Emission
Rates
Uncertainties exist in both the nature and magnitude of fugitive emissions.
Uncertainties hi the chemical nature of fugitive emissions principally arise from
limitations hi the understanding of the waste characteristics of the various fugitive
emission sources. For example, it is assumed that emissions from the waste water tank
are similar hi composition to the composition of emissions from the organic waste tank
farm. Furthermore, emissions from the tank farm are estimated assuming the waste
profile from the first year of operation is typical of long-term facility waste receipts. In
contrast with stack emissions, fugitive emissions are more strongly correlated with the

-------
chemical composition of the wastes, so that fluctuations in waste composition directly
affects the fugitive emissions.
Uncertainties in the magnitude of chemical-specific fugitive emissions arise from
uncertainties in the estimation of total fugitive emissions for the individual sources as
described in Volume HI, and the extrapolation of the results of the TANKS2 modeling
of tank farm emissions to the other sources of fugitive emissions, such as the container
building and the truck wash. Since the tank farm is expected to be the dominant source
of fugitive emissions, these extrapolations are not expected to materially affect the risk
assessment results.

V. IDENTIFICATION OF EXPOSURE
POPULATIONS AND PATHWAYS
A. Introduction
The exposure assessment step of the risk assessment process involves the identification
of the potentially exposed population, and the measurement or estimation of the magnitude of
exposure to individuals in that population. This chapter and the following two chapters
present the steps used in assessing exposure to the population in the vicinity of the WTI
facility. Within the exposed population, the magnitude of exposure is expected to vary by
individual, due to differences in individual characteristics and activity patterns, among other
factors. Therefore, a distribution of exposures across the population exists. Direct
measurement of this exposure distribution cannot readily be performed. Therefore,
subgroups within the population are identified that are expected to have similar exposure
because of similarities in activity and behavior patterns. This chapter describes the
approaches used to identify the exposed population, subgroups within that population, and
pathways of exposure; the following chapters provide estimates of environmental
concentrations based on the fate and transport of chemicals in the environment, and estimates
of human exposure of local populations to substances in affected environmental media.
In the WTI Risk Assessment Project Plan (U.S. EPA 1993b), a number of preliminary
population subgroups were identified. During the peer review process of the Project Plan,
several additional subgroups of the exposed population that may be at a higher risk due to
behavior patterns, proximity to the facility, or sensitivity were identified. The Peer Review
Panel suggested a number of additional population subgroups for possible consideration in the
risk assessment. A review of these subgroups is provided in Appendix V-5. Based on the
recommendations of the Peer Review Panel and the analysis described in Appendix V-5, one
additional exposure group, deer hunters, is included in the HHRA.
B. Population Subgroups Potentially Exposed to Stack Emissions
As stack emissions from the WTI facility disperse downwind, individuals may be
exposed to these emissions via direct inhalation. In addition, dry and wet deposition may
occur on soil, surface water, and vegetation. The deposited chemicals may then be taken up
by crops, livestock, and fish. Ingestion of locally raised crops and livestock, and
consumption of fish caught in local streams, lakes, and rivers represent potential pathways of

-------
indirect human exposure. Other indirect exposures, such as consumption of local milk and
milk products potentially affected by site emissions, are also possible.
Based on the characteristic activity and behavior patterns, the following subgroups have
been identified for the population in the study area surrounding the WIT facility:
• Adult non-farming residents;
• Child non-farming residents;
• Adult fanners whose diet consists partially of homegrown food products (e.g.,
meat, milk, vegetables); and
• Children of farmers whose diet consists partially of homegrown food products.
In addition to these subgroups, which are expected to comprise a significant portion of
the local population, three additional potentially exposed subgroups of the population have
been identified. Individuals in these subgroups may experience elevated exposures to
contaminants from the WTI facility due to their specific behavior pattern. These subgroups
are the following:
• Children (7 to 12 years old) who attend school in the area;
• Adult farmers whose entire diet is homegrown (referred to as subsistence farmers);
and,
• Children of subsistence farmers.
In addition to these subgroups, several groups have been identified as special population
segments who may be highly exposed because of their particular activity patterns. On this
basis, the following subgroups are included in the risk assessment:
• Adult and child residents whose diet consists partially of homegrown food
products;
• Breast-feeding infants (assumed to be all children under 1 year old);
• Subsistence fishermen (recreational fishermen who obtain a significant portion of
their diet from fish in local bodies of water); and
• Deer hunters who consume deer that have been exposed to contaminants in the
food chain.
Exposure is evaluated in this assessment for the specific activities listed above;
however, these exposures are expected to be incremental to exposure experienced through
other pathways by the individual performing the activity. Exposure from consuming

-------
homegrown vegetables, for example, applies to only those residents that have home gardens.
f For breast-fed infants and subsistence fishermen, the pathways listed above are likely to be
v the most significant source of exposure and, therefore, risk. Finally, only a small fraction of
the population would be anticipated to consume deer meat.
C. Potential Exposure Routes for Stack Emissions
The potential routes of exposure for the population subgroups that may be exposed to
stack emissions are tabulated in Table V-l and discussed in greater detail in the following
sections. Inhalation of stack and fugitive emissions is the only direct route of exposure; the
other routes in Table V-l are indirect exposure routes.
1. Air Exposure Routes
Direct inhalation of emissions from the WIT incinerator stack is the primary route
of airborne exposure for all population subgroups.
2. Soil Exposure Routes
A portion of the chemicals emitted from the stack is expected to be deposited on
surface soils in the vicinity of the facility. Residents working or playing outdoors may
^^ inadvertently ingest soil, and absorb chemicals through the skin during soil contact.
v These exposure routes are also assumed to apply to fanners, who work outdoors for
significant periods of time, and children who attend local schools and play outdoors.
3. Terrestrial Food Chain Exposure Routes
Chemicals deposited in the vicinity of the facility may accumulate in various parts
of the food chain. Chemicals may be incorporated in vegetation, crops, plants, and
forage, as a result of deposition on leaves, absorption from the soil through the roots,
and uptake of vapors from the air. Vegetation may, in turn, be consumed by local
residents, or by dairy cows, beef cattle, pigs, and poultry. The cows, cattle, pigs, and
poultry may also be exposed through ingestion of soil. Chemicals may then accumulate
in the meat from the livestock and milk from the cows. Therefore, consumption of
vegetables, beef, poultry, pork products, eggs, and dairy products from local farms and
gardens is a potential source of indirect exposure to stack emissions for humans. Each
of these food chain exposures is evaluated in the risk assessment.
4. Surface Water Exposure Routes
Chemical emissions may enter surface water in the vicinity of the facility through
/" deposition of stack emissions directly onto the water body or through runoff of
v. -'

-------
contaminated soil that enters the water body. Although a portion of the drinking water
for East Liverpool and Columbiana County is supplied from the Ohio River, surface
water is subjected to several treatment steps before use; therefore, significant exposure
through this pathway is unlikely, and is not evaluated quantitatively in this assessment.
It is possible that local residents may swim in surface water bodies and come into
contact with chemicals through ingestion and dermal absorption. A West Virginia
Department of Natural Resources (Pierce et al. 1983) study has indicated that a
significant amount of swimming occurs during the summer months in the Ohio River
near East Liverpool. This potential route of exposure, therefore, is considered in the
assessment. In addition, discussions with a local wildlife official indicated that
Tomlinson Run Lake, located approximately six miles south of the WTI facility, and
Little Beaver Creek, located two miles north and east of the WTI facility, are other
popular recreational areas in the vicinity of the WTI facility. Exposure to surface water
in these water bodies is evaluated.
5. Breast Milk Exposure Route
Lipophilic compounds, including dioxins and PCBs, may accumulate in body
tissues, preferentially concentrating in adipose tissue. Such compounds may then
accumulate in the breast milk of nursing women in the study area. Exposure to nursing
infants of mothers in the high-end subgroup is considered in the risk assessment.
6. Fish Consumption Exposure Route
Chemicals dissolved in surface water and adsorbed to sediments may be
transferred to and accumulate in fatty tissues of fish in local water bodies. Individuals
may consume fish caught locally and be exposed indirectly to stack emissions. For
residents living in the vicinity of the WTI facility, it is possible that a portion of the fish
diet may be derived from local waters, thereby increasing the potential exposure
through the food consumption pathway. An analysis of this exposure pathway is
presented in Appendix V-6. This analysis indicates that fish caught in the vicinity of
the WTI facility are not a significant source of food for the typical local resident. The
basis for this assumption is presented in Appendix V-6. It should be noted, however,
that a subgroup of the local population may exist that derives a significant fraction of
their diet from locally caught fish. This activity is referred to in this assessment as
subsistence fishing. Although no data or information are available to indicate that
subsistence fishermen actually reside in the vicinity of the WTI facility, exposure to
WTI-related contaminants by subsistence fishermen will be considered in the risk
assessment as a high-end exposure scenario.

7. Groundwater Exposure Route
It is possible that chemicals deposited on surface soils could become dissolved in
precipitation and percolate through surface soils to the groundwater. The Methodology
for Assessing Health Risks Associated with Indirect Exposure to Combustor Emissions
(U.S. EPA 1990a), evaluated the likelihood of this route of chemical transport using
worst-case assumptions in a leachate transport model for organic and inorganic
constituents.. U.S. EPA concluded that a very limited potential for contamination of
groundwater exists, and that further evaluation of this pathway was unnecessary. The
groundwater exposure pathway, therefore, is not considered in this assessment.
D. Population Subgroups Potentially Exposed to Fugitive Emissions
As noted in Volume HI, fugitive emissions occur in the form of organic chemical
vapors and as ash. The fugitive vapor emissions are comprised almost entirely of organic
compounds that volatilize from drums, tanks, valves, etc., and are transported off-site by
wind. Because of the nature of these fugitive emissions, i.e., volatile organic compounds, it
is assumed that inhalation would be the primary exposure pathway. Deposition of organic
vapors is generally considered to be insignificant and is, therefore, unlikely to result in
human health risks through indirect routes of exposure. In addition, as described in Volume
m, fugitive vapor emissions primarily occur from ground-level sources (with the exception
of the CAB system). The most significant impacts from ground-level sources are likely to
occur in the immediate vicinity of the source. The primary exposed populations in the
vicinity of the WTI facility, therefore, include residents (adults and children) that generally
live to the north and west of the facility. Because of the commercial/industrial location of
the WTI incinerator and the lack of farms in the immediate vicinity, significant exposure by
farmers to fugitive emissions is not expected to occur. Therefore, in this assessment, risks
due to fugitive vapor emissions via inhalation are estimated for three population subgroups:
• Adult non-farming residents;
• Child non-farming residents; and
• Children (7 to 12 years old) who attend school in the area.
Fugitive ash emissions, which are also released from a near ground-level source, will be
dispersed to a limited degree with the most significant impacts likely occurring in the vicinity
of the source. Because the ash is in particle form, deposition and subsequent exposure to
individuals in the vicinity of the WTI facility by indirect exposure pathways must be
considered. Therefore, risks associated with direct and indirect exposure to fugitive ash
emissions are estimated for the three population subgroups noted above. The indirect
External Review Draft
Volume V V-5 Do Not Cite or Quote
-------
pathways of exposure that are considered include ingestion of and dermal contact with soil,
and ingestion of homegrown vegetables. As noted earlier, fanning is not presently conducted
in the immediate vicinity of the facility, nor is it expected that farming will be conducted in
this area in the near future.
£. Uncertainties
In developing the scope of the HHRA, some assumptions are made in order to focus the
assessment on the most important exposure pathways and populations, thus reducing the
complexity of the assessment. In doing so, it is possible that all risks associated with the
WTI facility may not be accounted for; however, given the conservative nature of this
assessment, it is unlikely that risks are underestimated. The key assumptions used in
identifying exposure populations and pathways are summarized in Table V-2 along with a
rationale and qualitative descriptions of their potential effects on estimated risks. The key
assumptions used in identifying exposure populations and pathways are not expected to
impact the results of the HHRA significantly (i.e., the magnitude of effect is "low" for both
assumptions).
1. Uncertainties in the Identification of Exposure Populations
In this assessment, an attempt is made to identify subgroups within the exposed
population in the vicinity of the WTI facility that have similar behavior patterns and,
therefore, have similar levels of exposure. To this end, a range of exposure populations
are identified that include infants, young children, school-age children, and adults (both
farming and non-farming). It is possible, however, that a group of individuals may
exist that are more highly exposed than any of the identified population subgroups.
Consequently, exposure to such individuals would be underpredicted.
As noted above, several potential high-end exposure populations were suggested
for consideration as potential high-end exposures. After careful review, however, it did
not appear that any of the groups are either highly exposed or exposed significantly
different from populations already identified. Therefore, it does not appear that a
significant underestimate of risks has resulted from the process used to identify
exposure populations.
2. Uncertainties in the Identification of Exposure Pathways
The exposure pathways identified in this chapter cover a wide range of possible
activities likely experienced by individuals in the local population. There are several
potential exposure pathways that are not quantitatively evaluated in this assessment,
including primarily exposure to groundwater (through consumption, dermal contact, or
External Review Draft

-------
inhalation during showering) and exposure to surface water used by local municipalities
for drinking water. The groundwater exposure pathway is not considered because based
on existing information, it would not appear to be a source of significant risks to the
local population.
Surface water (the Ohio River) is used as a source of drinking water in the East
Liverpool area. Although this water is treated (including flocculation and
sedimentation, sand filtration, carbon absorption, and chlorination) before use by local
residents, it is possible that some types of contaminants (e.g., dioxins and heavy metals)
may not be entirely removed. Based on the results of the surface water-related
exposure pathway (Chapter VHT), however, the use of the Ohio River as a drinking
water source would not appear to present a significant source of risk.
As described in Appendix V-6, consumption of locally-caught fish by residents is
not considered in this assessment. Certain individuals within the population may be
exposed by this pathway, but it is estimated that, on average, risks by this pathway to a
resident are insignificant. To account for potential risks to individuals who consume
fish from local waters, risks to the subgroup referred to as subsistence fishermen are
estimated. Based on the insignificant risks estimated for this pathway (Chapter VQI), it
is estimated that risks to residents due to consumption of fish from local waters are also
insignificant.

VI. ESTIMATION OF ENVIRONMENTAL CONCENTRATIONS
A. Introduction
Individuals living and working in the vicinity of the WTI facility may be exposed to
substances emitted from the facility through both direct and indirect pathways. Direct
exposure occurs through inhalation of vapors and particles in the air. Indirect exposure
occurs as a result of dry and wet deposition of particles and vapor onto soil and vegetation,
and subsequent migration of these chemicals into other media. For example, stack gas
constituents that are deposited onto the soil can be incorporated into vegetation, which can
then be ingested by livestock. Consequently, human exposure may occur through ingestion
of vegetables or livestock grown or raised locally. Additionally, deposition of stack gas
constituents on local water bodies and runoff from watershed soils will result in
concentrations of contaminants hi surface water hi the vicinity of the facility.
In order to assess the risk of exposure to chemicals emitted from the stack, an estimate
of the concentrations of substances of potential concern in air, soil, vegetables, animal
products (e.g., meat, eggs, milk, game), surface water, fish, and mothers' breast milk is
necessary. The modeling of contaminant transport in air is discussed in Volume IV. For
other environmental media, concentrations are estimated using fate and transport models
designed to simulate the transport of substances in the environment over time. The models
used in this assessment are based on U.S. EPA guidance (U.S. EPA 1990a, 1993a, 1994c)
and reflect the current understanding of environmental fate and transport processes. This
chapter presents an overview of the models used. A more detailed presentation of the fate
and transport models, input values used in the models, and the basis for these values is
located hi Appendix V-7.
As noted hi Appendix V-7, whenever possible, site-specific data are applied hi this
assessment rather than using conservative default values. Substantial effort has been devoted
to obtaining site-specific information for use in estimating environmental concentrations,
including reviews of the scientific literature and conversations with local biologists and
agricultural agents. Table VI-1 presents the site-specific values used hi this assessment.
It is anticipated that use of site-specific values reduces the uncertainty associated with
the modeled results. It should be noted, however, that several of the models applied hi this
assessment are based on limited data and, therefore, contribute to the uncertainty hi the
results. The uncertainties that result from applying these models are discussed qualitatively
External Review Draft
Volume V VI-1 Do Not Cite or Quote
-------
at the end of this chapter and are evaluated quantitatively in Chapter IX. To compensate for
the uncertainty in the estimation process, conservative assumptions are generally applied in
this assessment so that estimated environmental concentrations are likely to be greater than
those actually associated with facility operations.
B. Estimation of Soil Concentrations
Stack gas constituents emitted to the atmosphere may deposit on surface soils in the area
surrounding the WTI facility due to dry and wet deposition of particles and vapor. The
concentration of chemicals in surface soil is required to 1) estimate potential human
exposures through soil ingestion and dermal contact with the soil, 2) predict uptake in
vegetation for human consumption and grazing animals, and 3) estimate concentrations in
surface water due to runoff of contaminated soil.
To estimate the chemical concentration in soil, the following equation is used (U.S.
EPA 1990a):
cs . \Dyd + Dy* + LDIF}[\ -«-*»*»] (100) (VI.1}
(2) (BD) (fa)
where:
CS = chemical concentration in soil, mg/kg
Dyd = dry deposition rate for particles, g/m2-yr
Dyw = wet deposition rate for particles, g/m2-yr
LUIF = vapor deposition rate, g/m2-yr
ks = soil loss constant, yr1
Tc = total time of deposition, yr
Z = soil depth, cm
BD = bulk density, g/cm3
Soil concentrations are estimated for surface (one centimeter) soils and root zone (20
centimeters) soil (U.S. EPA 1990a). In addition, soil concentrations within the upper 10
centimeters are estimated as an input to estimating surface water concentrations (U.S. EPA
1994c), assuming an agricultural watershed, which could have some tilled and some untilled
soils. Estimated soil concentrations at these depths are based on deposition rates of
constituents of concern assuming complete mixing within the soil layer of interest (1 cm, 10
cm, or 20 cm) and continuous operation of the facility over a period of 30 years. Dry and
wet deposition rates for particles (Dyd and Dyw) are predicted by the ISC-COMPDEP
model.

-------
The parameters values used in. the above equation are presented in Appendix V-7 along
i with the methodology and assumptions used in estimating soil concentrations. Site-specific
information needed to estimate soil concentrations include: fraction of organic carbon in soil;
bulk density of soil; annual precipitation, irrigation, runoff, and evapotransporation; soil
volumetric content; Universal Soil Loss Equation (USLE) constants for erosivity and
erodability; wind speed; and air temperature, viscosity and density. The values used in this
assessment are presented hi Table VI-1.
C. Estimation of Concentrations in Vegetation
The concentration of constituents in vegetation is necessary to estimate the exposure to
chemicals through ingestion of vegetation (i.e., vegetables and fruit) as well as to estimate
the uptake of constituents hi animals that feed on the vegetation (i.e., grain, forage, and
silage). Stack gas constituents may bioaccumulate hi plants through three mechanisms:
uptake by roots, direct deposition on exposed plant tissues, and air-to-plant transfer of vapor-
phase constituents. These mechanisms are discussed more fully by U.S. EPA (1990a and
1994c).
The magnitude of chemical uptake by produce is dependent on the type of vegetable and
its potential for exposure to the atmosphere. For example, contaminant deposition is more
likely to occur onto leafy vegetables (such as lettuce) than onto vegetables that are protected
V y' from the atmosphere (such as corn or root vegetables). Similarly, the uptake of chemicals
from the soil will differ for below ground and above ground vegetables. Therefore, four
types of produce classes are considered in the risk assessment:
• Leafy produce (e.g., lettuce, broccoli, forage);
• Above ground protected produce (e.g., corn, peas, gram);
• Above ground exposed produce (e.g., tomatoes, green peppers); and
• Root produce (e.g., carrots, onions).
Assumptions presented hi Appendix V-7, for each of these classes of produce are used
in the following equations to estimate concentrations of chemicals hi produce. The overall
approach and important, site-specific input parameters are described below; however, details
on model application are presented in Appendix V-7.
The total concentration of a constituent in a given plant (CV) due to root uptake (P^),
,™^
( direct deposition (Pdj), and air-to-plant transfer (PVj) can be calculated as follows:

PVj = concentration of constituent in i* plant group due to air-to-plant transfer,
mg/kg
Root Uptake
The constituent concentration from root uptake (Pr) for above ground vegetation (i.e.,
above ground exposed and protected vegetables, and leafy vegetables) is dependent on the
soil concentration (CS) and a chemical specific plant/soil bioconcentration factor
Prt = (CS) (Brt) (VI-3)
where:
Prj = concentration of constituent in i* plant group due to root uptake, mg

CS = soil concentration of constituent after the total period of deposition, mg

Br; = plant/soil bioconcentration factor for the i* plant group, (mg constituent/kg

Baes et al. (1984) present bioconcentration factors for the metals evaluated in the
HHRA. For organic chemicals, the bioconcentration factors are calculated using an equation

Briggs (1982) developed a regression equation dependent on the octanol/water partition
coefficient, K^, to calculate RCFj values for organic compounds, presented in
Appendix V-7.
VGbg is a factor introduced into the calculation of contaminant concentrations to reflect
the reduced translocation of compounds in bulky, below ground vegetables, such as carrots
and potatoes (U.S. EPA 1994c). In general, the contaminant concentrations measured in the
barley roots of the Briggs (1982) experiments would be representative of the levels of
compounds in the outer few millimeters of below ground vegetation, but much higher than
the average concentration hi the whole vegetable. Thus, a VGbg value of 0.01 is used for all
substances of concern, as recommended by U.S. EPA (1994a).
Direct Deposition
The factors related to the plant concentration attributable to direct deposition on exposed
plant tissues (Pdj), as shown in Appendix V-7, are as follows:

and dry deposition rates are provided from the air dispersion modeling. Equations to
calculate Rpj, and kp are also presented hi Appendix V-7. Values for Tpj and Ypj are
obtained from Pennsylvania Agricultural Statistics Service (PDA 1994) and the Census of
Agriculture (USDC 1993a,b,c), as shown in Table VI- 1. This route of exposure for plants is

significantly less susceptible to direct deposition.
Air-to-Plant Transfer
Plant concentrations attributable to air-to-plant transfer are dependent on the vapor-
phase air concentration, and an air-to-plant biotransfer factor, as shown in the following
equation. This type of transfer applies only to above ground exposed plants (i.e., does not
include root vegetables or above ground protected plants).

factors are related to various physical and chemical properties of the constituents. Equations
recommended by U.S. EPA (1994c) to estimate Bv; are also presented in Appendix V-7. Cy
is predicted from the air dispersion modeling. VG^ is a correction factor similar to VGbg
that is introduced to reflect the difference between the concentration hi the outer few
millimeters and the average concentration in the whole vegetable. U.S. EPA (1994c)
recommends that VGag should be set equal to 0.01 for unspecified above ground fruits and
vegetables, 1.0 for leafy vegetables and forage, and 0.5 for silage and 0 for grain. These
recommendations are based, hi part, on the reduction of chemical concentrations in
unspecified fruits and vegetables as a result of cleaning and peeling; the direct analogy of
leafy vegetables and forage to azalea leaves, the experimental leaves on which the equation
was based; the assumption that silage can be considered part leafy and part protected; and the
assumption that gram is fully protected. The density of air, related to the site-specific air
temperature, is presented hi Table VI- 1.

D. Estimation of Meat, Eggs and Milk Concentrations
Stack gas constituents in soil, surface water, and plants may accumulate in animals that
ingest these media while grazing. The uptake of chemicals by livestock is required to
estimate human exposure to constituents that accumulate in milk and meat products from
animals that are raised in the vicinity of the WTI facility. U.S. EPA (1990a; 1994c) presents
a food chain model to estimate concentrations of stack gas constituents hi beef, milk, pork,
poultry, and eggs, etc. This model considers the concentration of constituents in plants, and
soil, the quantity of plants, and soil that animals consume, and the biotransfer (Ba) or
bioconcentration factor (BCF) of each type of animal tissue. According to U.S. EPA
(1994c), uptake of constituents via inhalation or ingestion of contaminated water is
insignificant compared to soil and fodder ingestion and is, therefore, not considered hi this
assessment.
The algorithm used to estimate constituent concentrations in animal tissues is expressed
as follows:

These equations include uptake of chemicals by livestock through ingestion of fodder
and soil. Appendix V-7 presents the necessary input parameters on the type and amount of
plants and soil consumed by various animals.
The biotransfer (bioconcentration) factors used in this assessment are derived from three
sources. For the dioxin-like compounds, BCFs recommended by U.S. EPA (1994b) are used
(see equation (VI-8)). For the organic chemicals, regression equations presented by Travis
and Arms (1988) and recommended by U.S. EPA (1993a) relating Ba to K^ are used. For
metals, Ba values presented by U.S. EPA (1995c), Baes et al. (1984), and other literature
sources are used.
The regression equation used to estimate biotransfer factors for organic chemicals
developed by Travis and Arms (1988) is based on data for a limited group of compounds
comprised primarily of pesticides and chlorinated compounds. In the HHRA, biotransfer
factors estimated using this regression equation are applied to the non-dioxin organic
compounds. Sufficient scientific evidence exists (Ikeda 1980; Astill 1989; Daniel and Bratt
1974; Albro 1986), however, to indicate that bis(2-ethylhexyl)phthalate is metabolized in the
body of mammals and does not bioaccumulate to the extent implied by using the Travis and
Arms regression equation. Therefore, a "metabolism factor", MF, is introduced in equation
(VI-7) to account for metabolism in beef cattle, milk cows, and humans. The value of MF is
estimated to be 0.01 for bis(2-ethylhexyl)phthalate based on a study by Ikeda et al. (1980).
Additional discussion of the metabolism, absorption, and excretion of bis(2-
ethylhexyl)phthalate is presented in Appendix V-7. For all other compounds, the value of
MF is conservatively assumed to be 1.0.
Fy is a site-specific value that has been obtained from discussions with a local
agricultural agent (Miller 1993), as shown in Table VI-1. This value equals 0.9 for grain
and silage for dairy cows and 1.0 for all else. These values imply that only 10% of a dairy
cattle's grain and silage intake is imported from outside areas with the balance from local
sources.

E. Estimation of Surface Water Concentrations
Surface water bodies may receive stack gas constituents from direct deposition, from
runoff of contaminated soils in the vicinity of the WTI facility, and from eroded soils. The
concentration of constituents hi the surface water is required to estimate human exposure
through surface water ingestion and dermal contact, and to estimate the uptake of chemicals
from the surface water by fish. U.S. EPA (1994c) presents a model to estimate constituent
concentrations in surface water bodies. This algorithm contains several simplifying and
conservative assumptions, as follows:
• Soil concentrations within a watershed are uniform;
• Chemicals enter into a surface water body via soil erosion, surface runoff, and
direct deposition; and
• Steady-state is achieved between concentrations in the dissolved phase in the water
column, concentrations hi the suspended sediment, and concentrations in bottom
sediments.
To determine surface water concentrations, the concentration on the suspended sediment
must be estimated. The suspended sediment concentration is calculated from the total load of
constituent to the water body and the annual amount of suspended sediment, as presented in
Appendix V-7 and summarized below:
where:
Cssed = concentration on suspended sediment, mg/kg
p = annual contaminant entry via erosion + direct deposition, mg/yr
= annual amount of suspended sediment, kg/yr
The values for p and are determined by the equations in Appendix V-7.
Once the suspended sediment concentration is determined, the dissolved concentration is
estimated by calculating a mass balance between the mass of contaminants entering the water
body and the amount that partitions to the three compartments hi the water body: a) dissolved
hi the water column, b) sorbed to suspended material, and c) sorbed to particles settling to
the bottom. Specifically, the dissolved concentration is estimated by the following equation:

The equations and parameter values used in this assessment are presented hi Appendix
V-7. Site-specific values are needed for several parameters to characterize the water body
and watershed area (e.g., water body surface area, volume, and total suspended solids, and
watershed area) and are presented in Table VI- 1. These values are obtained from the
literature and are described further in Appendix V-7. The chemical-specific partition
coefficient, Kdssed, is estimated from the organic carbon coefficient, K^., and the fraction of
organic carbon in the suspended sediments.
F. Estimation of Chemical Concentrations in Fish
Stack emissions may enter local surface water bodies through both direct deposition and
deposition onto watershed soils, followed by runoff and erosion into the surface water
bodies. These chemicals may then accumulate in fish tissue. The concentration of
constituents in fish is required to estimate human exposure to constituents via ingestion of
fish. U.S. EPA (1990a) presents a model to estimate chemical concentrations in fish. This
model, which calculates constituent concentrations by considering the water concentration and

a bioconcentration factor, is generally appropriate for chemicals with high water solubility
and low affinity for sediments.
The water concentration and a bioconcentration factor are necessary to estimate
concentrations of constituents in fish, as shown hi Appendix V-7 and as follows:
CF = C (BAF) (VI-12)
where:
CF = concentration in fish, mg/kg
Cwat = dissolved water concentration, mg/L
BAF = bioaccumulation factor, L/kg
Estimation of water concentrations has been described previously. BAFs are calculated
as the product of a bioconcentration factor (BCF) and a food-chain multiplier (FCM) (U.S.
EPA 1995d). U.S. EPA (1995d) presents FCMs for various trophic levels based on the
logarithm of K,,w. The FCMs for the piscivorous fish trophic level are used in this
assessment. BCF values for specific substances of concern are compiled from the scientific
literature and other sources, e.g., the U.S. EPA AQUIRE data base.
An alternative equation is applied to dioxin-like compounds because of their low water
solubility and high affinity to sediments (Appendix V-7), as follows:
L(BSAF)(flipid) (VI-13)
where:
Qed = bottom sediment total concentration, mg/kg
OCsed = fraction organic carbon in bottom sediment, unitless
BSAF = biota to sediment accumulation factor, unitless
flipid = fraction lipid content of fish, unitless
Default values are used for OCscd and flipid because of the likely variability in site-
specific data; BSAF is chemical-specific, and values recommended by U.S. EPA are used hi
this assessment (U.S. EPA 1994c). Specific parameter values used in this assessment can be
found in Appendix V-7.

G. Estimation of Breast Milk Concentrations
Constituents in breast milk provide an exposure pathway for infants, a potentially
sensitive population subgroup. For dioxin-like compounds, Smith (1987) has developed an
approach to estimating concentrations in breast milk. This approach is based on the half-life
of dioxins within the human body, estimated as five to seven years (U.S. EPA 1994a), and is
shown as follows:
(m) (h) (fJ/LT
(0.693) (£) I ED
C = \ (VI-14)
where:
Cnu,, = chemical concentration in mother's milk fat, mg/kg
m = lifetime average maternal intake of dioxin-like compound, mg/kg of body
weight/day
h = half-life of dioxin in adults, days
f! = proportion of ingested dioxin-like compound stored in fat
f2 = proportion of mother's weight that is fat, kg maternal fat/kg total body weight
LT = lifetime, days
ED = exposure duration, days
The lifetime average maternal intake, m, is the average daily dose the mother receives during
her lifetime, rather than the dose during the period of exposure. Therefore, the LT over ED
factor is included to correct for the lifetime averaging used in the estimation of maternal
intake (i.e., to estimate an average daily dose during the period of exposure). Parameter
values used hi the assessment are shown in Appendix V-7.
Travis et al. (1988) presents a generic, alternative methodology to estimate breast milk
concentrations for chemicals not amenable to the Smith (1987) approach (i.e., chemicals
other than dioxins/furans and PCBs). This methodology is summarized in Appendix V-7 and
below:
(F_J (Mf) (VI-15)
where:
Cmm = constituent concentration in mother's milk fat, mg/kg
Mti = maternal total daily intake from all routes of exposure, mg/day

-------
?,„,„ = mother's milk fat biotransfer factor, day/kg
MF = metabolism factor, unitless
The method used to estimate the mothers' total daily intake is summarized in Appendix
V-7. Biotransfer factors are a function of K^ and are calculated by the modified Travis et
al. (1988) equation shown hi Appendix V-7. As noted earlier, the value for MF is 1.0 for
all chemicals, except for bis(2-ethylhexyl)phthalate for which a value of 0.01 is assigned.
Additional discussion of this approach is presented hi Appendix V-7.
Inorganic compounds, including metals, are not generally lipophilic and thus
accumulation hi mother's milk is not anticipated.
H. Uncertainties
Uncertainties hi estimating chemical concentrations hi the environment are classified as
follows:
• Uncertainties inherent hi the fate and transport models used to predict
environmental concentrations; and
/ " • Uncertainties hi the parameters values used as inputs to the fate and transport
v models.
These two types of uncertainty are discussed separately below. A quantitative
evaluation of the effect of uncertainties in the environmental modeling is presented hi
Chapter IX. In addition, Table VI-2 identifies the key assumptions used hi estimating
environmental concentrations. The basis for each assumption is provided in the table, as
well as the estimated direction and magnitude of effect that the assumption could have on the
results of the HHRA. As indicated in Table VI-2, several of the assumptions used hi this
chapter could significantly impact the results of the assessment, if these assumptions are
incorrect. Significant uncertainty is associated with the accuracy of the fate and transport
models because of the simplifying assumptions used hi the derivation of these models and the
limited, largely lab-scale, validation that has been conducted. As noted earlier, conservative
assumptions are applied hi this assessment to account for this uncertainty.
Chemical-specific input values used hi the fate and transport equations may also have a
significant effect on the results of the risk assessment. Specifically, K^ values used in many
of the models are highly uncertain and may have a significant impact on estimated
concentrations hi environmental media. In addition, estimates of K^ values for some
chemicals range over several orders of magnitude.

1. Uncertainties Inherent in the Fate and Transport Models
As outlined in this chapter, it is necessary to rely on models to predict chemical
behavior in the environment following release from the WTI facility. These models,
while based on fundamental scientific principles, represent a simplification of the
processes that will determine actual chemical concentrations in air, soil, surface water,
and other environmental media. Such simplification can, in theory, lead to either an
overestimation or underestimation of chemical concentrations in the various
environmental media! In this risk assessment, models are selected that are more likely
to overestimate, rather than underestimate, chemical concentrations in the environment
given conservative input parameters to these models.
The models used to predict chemical concentrations in soil, vegetables, meat, milk,
surface water, fish, and breast milk are based primarily on the scientific principles of:
1) mass balance, and 2) chemical partitioning. Use of mass balance principles ensures
that the total mass of a contaminant is taken into account, for example, in predicting
soil concentrations. Chemical partitioning indicates what fraction of the total mass will
be transferred from one medium to another and dictates parameters such as biotransfer
factors (BTFs) and bioconcentration factors (BCFs). Uncertainty is associated with both
mass balance and partitioning model approaches, due to incomplete knowledge in
several areas, including the nature, rate, and extent of chemical degradation in the
environment, the types of chemicals produced by such degradation, and the chemical,
physical, and biological factors that determine the movement of a chemical from one
environmental medium to another.
Specific uncertainties associated with the fate and transport modeling used for
dioxin and furan cogeners are discussed below because these groups of compounds are
likely to be the primary contributor to total cancer risk due to human exposure to
incinerator stack emissions. This risk assessment relies on the fate and transport
modeling described in the U.S. EPA document: Estimating Exposure to Dioxin-Like
Compounds: Volume III (U.S. EPA 1994c), which was recently reviewed by the U.S.
EPA's Science Advisory Board (U.S. EPA 1995e). The Science Advisory Board's
comments on some of the major fate and transport modeling issues for dioxins and
furans are summarized below.
• The role of combustor emissions on long-term accumulation of dioxins and furans
in sediments and soil requires further study.
External Review Draft
Volume V VI-14 Do Not Cite or Quote
-------
• The existing air dispersion models adequately simulate the atmospheric transport of
vapor-phase dioxins and furans, but are unable to account for partitioning
processes onto soil, vegetation, and water surfaces.
• The available qualitative evidence suggests that the lesser chlorinated dioxins and
furan congeners are degraded by photolysis between the source and environmental
sinks. This degradation is not accounted for in the fate and transport modeling.
• The primary physical/chemical properties of the individual dioxin and furan
congeners, other than 2,3,7,8-TCDD, are developed based on limited data, which
introduces some uncertainty hi the estimates of environmental concentrations.
• Validation of the vapor/particle portioning model (Bidleman 1988) is required over
the broad temperature range typical of environmental conditions.
Further details regarding the Science Advisory Board's comments may be found
hi: An SAB Report: A Second Look at Dioxin. Review of the Office of Research and
Development's Reassessment of Dioxin and Dioxin-Like Compounds by the Dioxin
Reassessment Review Committee (U.S. EPA 1995e).
2. Uncertainties in Input Parameters
The fate and transport models used to predict concentrations hi the environment
require inputs regarding both the environmental media (e.g., soil density, wind speed,
fraction organic content in soil and sediment) and the physical/chemical properties of
the chemicals of concern (e.g., bioconcentration factors, solubility, Henry's Law
constants). In some cases, only limited data are available regarding a property of an
environmental medium or chemical. For example, biotransfer factors have not been
directly measured for certain chemicals considered hi this assessment, and thus are
extrapolated using regression equations based on available data for other chemicals.
Many of these regression equations are based on the octanol/water partition coefficient,
K,,w. The value of K^ for many chemicals is highly uncertain, with estimated values
for a single chemical potentially ranging several orders of magnitude. Furthermore,
regression equations are often based on the study of a limited number or specific class
of compounds (e.g., pesticides). The uncertainty associated with applying these
regressions to compounds outside the class of compounds used in the original study may
be significant. These data gaps introduce uncertainty hi the model results. In other
cases, there is considerable variability in the available data, and a single value from a

range or distribution of reported values for a parameter is selected for use in the risk
assessment.
It is not possible to rigorously quantify the effect of all uncertainties introduced
into the risk assessment by the fate and transport models and inputs to these models.
However, a quantitative evaluation of the uncertainties in the fate and transport
modeling for two types of chemicals of primary concern hi the risk assessment (dioxins
and metals) is performed, and is presented hi Chapter IX.

VH. ESTIMATION OF EXPOSURE DOSE
A. Introduction
Estimates of chemical dose developed in the exposure assessment are used to estimate
the risks to individuals and to the collective population in the vicinity of the WIT facility.
U.S. EPA guidelines recommend that the presentation of such estimates for individuals arid
populations be made using several descriptors (U.S. EPA 1992a; 1995a). For example, the
guidelines call for estimating the "high-end" exposure, which is an estimate of the exposure
of individuals in the upper end of the exposure distribution of the population. Conceptually,
the U.S. EPA guidelines define high-end exposure as within the upper ten percent of the
exposure distribution, but not higher than the upper bound of the distribution (i.e., not above
the expected highest value in the true exposure distribution of the population). The
guidelines also recommend the development of "central tendency" exposure estimates to
reflect the exposure borne by typical members of the exposed population, i.e., those
approximately at the median of the exposure distribution.
In order to estimate the exposure distribution of the population, it is necessary to
develop sufficient data to characterize the exposed population. The method used in this
assessment to estimate the exposure distribution for the population is based on dividing the
population into subgroups (identified in Chapter V) made up of individuals expected to share
the same exposure characteristics. These subgroups can be characterized by developing an
exposure distribution using site-specific information concerning:
• The location of the exposure subgroups with respect to the WTI facility;
• Typical activity patterns that generally characterize each subgroup; and
• The number of individuals that comprise each subgroup.
To fully develop an exposure distribution for a subgroup requires detailed information
concerning the activity and behavioral patterns of individuals in the subgroup, including the
percent of time spent in performing different activities at designated locations (e.g., indoors,
outdoors, garden, school), dietary intake estimates, sources of different food groups within
the area, age and sex of individuals in the population, and other data characterizing human
behavior of the population. For example, it is important to understand the extent to which
food consumed locally is derived from local sources rather than imported from more distant

-------
sources. This aspect is particularly important in assessing the fraction of consumed food that
may be affected by emissions from the WTI incinerator.
It is recognized that gaps in this information exist, and that some of the activity and
behavioral patterns will change over time. However, this methodology should provide a
reasonable estimate of the exposure distribution within each subgroup. After distributions
have been developed for each subgroup, they can be combined to approximate the exposure
distribution for the population as a whole.
The Peer Review Panel emphasized the importance of obtaining site-specific data,.
including information on the amount of consumed meat derived from local sources, the
amount of fish derived locally, and the amount of food consumed from local home gardens.
As described in the Project Plan (U.S. EPA 1993b), surveys have been conducted to obtain
site-specific data of this nature. The data collected from these efforts, as well as subsequent
data collected, are described in this chapter.
B. Estimation of Human Exposure
The fate and transport models described in the preceding chapter provide a means of
estimating environmental media concentrations of substances released from the WTI facility.
Exposure to these substances by individuals living and working in the vicinity of the facility
may occur as a result of contact (e.g., inhalation, ingestion, dermal contact) with
contaminated media. To quantify the magnitude of this exposure, environmental media
concentrations are combined with exposure factors in exposure dose equations using the
methodology described below.
1. Estimation of Exposure Dose
Exposure to a chemical by an individual may occur by either intake, where the
chemical enters the body through a body opening (e.g., the mouth), or uptake, where
the chemical is absorbed through a body boundary (e.g., the skin). Exposures through
both intake and uptake are of interest in the risk assessment.
Theoretically, the dose may be measured at any one of several locations between
the point of contact and the location in the body where the chemical takes effect. It is
general practice to estimate either the dose at the point of entry into the body (referred
to as the potential dose), or the dose that has been absorbed through a body boundary
and is available for biological action (referred to as the internal dose), depending on the
exposure route being assessed (U.S. EPA 1992a). In addition, the dose is estimated as
an average dose rate over time.
When considering intake processes (e.g., ingestion, inhalation), the potential dose
rate is estimated. For the evaluation of noncancer health effects, this dose rate is

-------
referred to as the average daily potential dose (ADD^ and is averaged over the
exposure duration. In evaluating cancer risks, the daily potential dose is averaged over
the individual's lifetime and is referred to as the lifetime average daily potential dose
(LADDpJ. For uptake processes, where the chemical crosses a body boundary, such as
the skin, the internal dose rate is of interest. In this case, the average daily internal
dose (ADDjJ and the lifetime average daily internal dose (LADDjJ are estimated when
assessing noncancer and cancer health effects, respectively. Although it is theoretically
possible to estimate an internal dose for intake processes, such as ingestion and
inhalation, by using factors that account for the transfer of chemicals across internal
boundaries (e.g., lungs, stomach), the chemical-specific data are seldom available to
perform such an assessment reliably.
The rate of chemical intake and/or uptake is dependent upon the concentration of
chemicals in environmental media to which individuals come into contact, and the
nature and duration of contact. The concentration of chemicals in environmental media
is estimated using fate and transport models (as described in Chapter VI). The nature
and duration of contact with contaminated media is estimated for generally homogenous
subgroups within the population, based on assumptions about behavior. As
recommended hi U.S. EPA guidelines (U.S. EPA 1992b), these assumptions of
behavior can be represented by discrete values. These discrete values, referred to as
exposure factors, represent such parameters as the exposure duration, exposure
frequency, and the media intake rate.
The exposure factors are combined with the media concentrations in equations that
estimate the ADD or the LADD. These equations, used to estimate the dose (potential
or internal), are dependent on the route of exposure (e.g., ingestion, inhalation, dermal
contact with water). In the following sections, the equation used to estimate the dose
for each route of exposure is presented. The input parameters for these equations, i.e.,
exposure factors, are presented and described in Appendix V-8.

milk is calculated using the following equation:

Noncarcinogenic health effects due to infant ingestion of breast milk are not
considered in this assessment due to the significant uncertainty in applying health
effects/toxicity data to infants (U.S. EPA 1994a).
2. Exposure Factors
The dose equations identified in the preceding sections include various exposure
factors, such as contact rate, and exposure frequency and duration. Each of these
factors has a range of possible values based on the population subgroup and exposure
pathway of interest. Estimation of typical exposures for each subgroup is performed by
combining exposure factors reflecting typical activity and behavior patterns of the
subgroup with media concentrations to which the subgroups may be exposed. Typical
External Review Draft
Volume V Vn-9 Do Not Cite or Quote
-------
values for the exposure factors used in the various dose equations listed above are
presented in Appendix V-8. The high-end of the population exposure distribution
includes highly exposed subgroups from areas most significantly impacted by the
facility. A further assessment of the variability of exposure to these individuals is
described in Chapter VIE, by applying high-end exposure factor values. A summary of
these values is presented in Appendix V-8.
In Appendix V-8, typical values refer to values that represent either the mean or
the median of the distribution of possible values. As noted.in the Exposure Assessment
Guidelines (U.S. EPA 1992b), for skewed or truncated distributions, the median may be
more representative of the central tendency value than the mean. Most exposure factor
distributions are skewed or truncated; therefore, when possible, the median value is
used in the HHRA. High-end represents the values toward the upper end of the
distribution, generally 90* percentile and greater.
As described in Appendix V-8, site-specific information and U.S. EPA guidance
(U.S. EPA 1989b; 1990b; 1992c) are generally relied upon in estimating appropriate
values for the exposure factors. In some instances, professional judgment is applied in
the selection of exposure factor values. A discussion of the site-specific data relied
upon in developing exposure factors is provided in the following sections. Assumptions
based on U.S. EPA guidance or professional judgment used in developing exposure
factors are discussed in Appendix V-8.
C. Site-Specific Exposure Data
In order to provide a more complete understanding of the exposure to the population
surrounding the WIT facility, site-specific data characterizing this population, land use
characteristics, local topography, and the local meteorology are used wherever possible in the
risk assessment. These site-specific data are used in the risk assessment to estimate the
potential exposure to the actual population living or working in the area surrounding the WTI
incinerator. Table vn-1 summarizes the exposure factors used in the exposure dose
equations for which site-specific data are available.
1. Home Gardening Practices
An informal home gardening survey was conducted in June 1993 by the East
Liverpool Board of Health in six sections of East Liverpool: 1) East End (half a mile
northeast of WTI); 2) Dixonville (half a mile north of WIT); 3) Northside (2 miles
northwest of WIT); 4) LaCroft (3 miles northwest of WTI); 5) Pleasant Heights
(2 miles west of WIT); and 6) Downtown (2 miles southwest of WIT). This survey
indicated that approximately 30 percent of local residents have home gardens. Of the
External Review Draft
Volume V VII-10 Do Not Cite or Quote
-------
residents with home gardens, the Board of Health contacted 100 residents, to ascertain
gardening practices, such as the types of vegetables and fruit grown and percentage of
their total vegetable/fruit intake that is homegrown. The data from the home gardening
survey provide a general indication of gardening practices in the East Liverpool area,
and are tabulated in Tables VII-2 and VII-3. These tables include the general locations
of vegetable gardens in the East Liverpool area, the vegetables and fruit grown in home
gardens, and the estimated portion of vegetable and fruit diet that is homegrown. The
information on home gardening practices collected by the Board of Health is used to
estimate the fraction of homes in the area surrounding WTI that have gardens and the
fraction of residents' fruit and vegetable diets that are homegrown, as indicated in Table
VH-1.
2. Local Fishing Practices
Fishing practices in the Ohio River valley in the vicinity of the WTI facility were
evaluated by the Ohio and West Virginia Departments of Natural Resources (DNR) in a
joint recreational fishing study (ODNR 1994a) conducted to identify the amount of
fishing and the types of fish being caught along the Ohio River between the
Ohio/Pennsylvania border (Ohio River Mile 40.1) and Greenup Dam, 300 miles
downstream (ORM 341). This 300-mile study area was subdivided into 32 survey
areas, which include survey points (embayments and tailwaters), and pools. Four of the
32 survey areas (locations #1 to #4) are in the general vicinity (30-kilometer radius) of
the WTI facility (located at ORM 41.5). These four survey areas were assumed to be
representative of the Ohio River in the vicinity of the WTI facility. The four survey
areas cover the entire stretch of the Ohio River from the Ohio/Pennsylvania border to
Steubenville, Ohio (ORM 40.1 to ORM 69.5).
The DNR study was conducted between April and November 1992. The amount
of fishing that occurs between December and March is believed to be insignificant in
comparison with other parts of the year and should not appreciably affect the results of
this survey. Therefore, the data collected in this study are assumed to reflect annual
data. Table VII-4 summarizes the recreational fishing data obtained from the
Ohio/West Virginia DNR study (ODNR 1994a).
The Ohio River Valley Sanitation Commission (ORSANCO) conducted an
electrofishing survey (between ORM 21.6 and ORM 55.5) from 1991 to 1993
(ORSANCO 1994) that provides the average weight of fish from the Ohio River
corresponding to various size ranges. In addition, ORSANCO performed fish tissue
sampling from 1987 through 1992 at various locations in the Ohio River valley. The
resulting data include moisture and lipid content, length and weight information, and

pesticide, PCB, and metals concentration in fish tissue (ORSANCO 1988; 1990; 1993).
As described in the analysis of the fishing data in Appendix V-6, the recreational
fishing data do not suggest that locally caught fish are a significant portion of the fish
diet for typical local residents. Furthermore, the data discussed above are not sufficient
• to indicate the presence or absence of subsistence fishing in the Ohio River Valley area.
Nonetheless, subsistence fishing is evaluated using exposure factors developed from
national statistics, as described in Appendix V-6.
3. Local Fanning Practices
Information concerning local farming practices has been obtained from interviews
with local Agricultural Extension agents who are familiar with farming practices in this
area of Ohio, Pennsylvania, and West Virginia. In addition, data on local beef fanning
and cattle raising practices were compiled from Agricultural Statistics Service
(associated with the Departments of Agriculture hi Ohio, Pennsylvania, and West
Virginia) reports and from federal Department of Agriculture reports. The following
sections summarize the site-specific data collected on beef and dairy farming practices
in the area surrounding the WTI facility.
a. Beef Fanning
The primary source of information on beef farming statistics is agricultural
data compiled by the Agricultural Statistics Service associated with the
Departments of Agriculture in each of the three states (Ohio, Pennsylvania, West
Virginia) located in the vicinity of WTI (ODA 1994; PDA 1994; WVDA 1994).
Summaries of livestock data are published annually and include such parameters
as: total number of cattle/calves in the state, number of calves born annually, and
information on slaughter and marketing of beef cattle and calves.
A summary of beef farming data for Ohio, Pennsylvania, and West Virginia
is provided in Table VH-5. The value for total cattle/calves in Table vn-5 is the
number of cattle related to beef and dairy farming that were reported in the state
as of January 1, 1993. This value includes all types of cattle including: milk
cows; beef cows used in calving operations; milk and beef heifers (i.e.,
replacement cows); steers; bulls; and calves.
Information on the disposition of beef cattle and calves is also provided in the
Agricultural Statistics Service summaries. The number of cattle and calves that
are slaughtered in registered slaughtering facilities in each state is shown in
Table Vn-5. The source of the slaughtered animals, however, is not available
because processing facilities are not required to keep records on the origin/owner

Volume V VH-12 Do Not Cite or Quote
-------
of the cattle sold for slaughter. A report on the state of the slaughtering industry
in Ohio (Distad 1992) indicates that Ohio does not have any "large" capacity cattle
slaughtering facilities, but does have many smaller operations with slaughtering
capacities of less than 1,000 head per year. Furthermore, the report indicates that
Ohio is a net exporter of beef for slaughter, as indicated by the greater number of
steers in the state than head slaughtered (i.e., 229,000 head to 185,000
slaughtered). The same situation would appear to apply in West Virginia.
Pennsylvania, on the other hand, is home to two of the largest cattle
slaughtering facilities in the country (10th and 12th largest overall) with a total
annual slaughtering capacity of approximately 740,000 head (Distad 1992); a large
fraction of the 740,000 head are likely to be imported from out of state. Because
of these two very large plants (both of which are located in the eastern part of the
state) Pennsylvania is a net importer of beef cattle for slaughter. For the purpose
of this assessment, it is necessary to estimate the number of cattle that are raised
as well as slaughtered in Pennsylvania. Including the data from these importing
plants would significantly overestimate the number of locally raised, locally
slaughtered cattle. To obtain an estimate of Pennsylvania-bred cattle slaughtered
in the state, therefore, the 740,000 head slaughtered at the large slaughtering
houses in eastern Pennsylvania are subtracted from the state total slaughter. The
(^ resulting estimate, 229,000 head, is more consistent with the other states in the
area and with the 220,000 beef steers raised in the state (see Table VII-5). This
value, therefore, is assumed to approximate the number of Pennsylvania-bred cattle
slaughtered in the state.
County-specific beef farming data available from the Agricultural Statistics
Service data summaries are limited. Therefore, a number of parameters are
estimated based on state-wide data, as shown in Table VII-6. This methodology
assumes that beef raising and slaughter practices are similar across all parts of a
state, which may not necessarily be true. To address this uncertainty, agricultural
extension agents for the counties located in the vicinity of the WTI facility were
interviewed regarding local beef cattle raising practices. Although no actual data
were obtained from these sources, judgments concerning local farming practices
proved to be a valuable resource to supplement the state-wide data.
For example, the primary type of beef farming performed in the eastern
Ohio/western Pennsylvania area involves cow/calf operations that raise cows to
produce calves. These calves are raised locally for six to nine months, weaned,
and generally sold to feedlots out of state (personal communication, county

agricultural extension agents, August 1994). In other portions of these states
(Ohio, Pennsylvania, West Virginia), this practice may not be as commonplace.
As a result of the regional variances, the state-wide statistics, therefore, may
not accurately represent local beef farming practices. For example, according to
the state-wide data, the fraction of calves born that are marketed ranges from 0.23
for Ohio to 0.51 for West Virginia (as shown in Table VII-5). Discussions with
local agricultural extension agents indicate, however, that 60 to 70 percent of a
local calf crop in any given year is marketed (sold at auction to feedlots in western
Ohio or the western U.S.) and may range as high as 80 to 90 percent of the local
calf crop, but is rarely below 50 percent. Because most calves are sent out of the
area for slaughter, it is likely that estimates of local slaughter provided in
Table Vn-6, overestimate actual local slaughter in these counties. The published
and estimated beef statistics for three counties in the vicinity of the WTI facility
are provided in Table Vn-6 for the following counties: Columbiana, Ohio; Beaver,
Pennsylvania; and Hancock, West Virginia (ODA 1994; PDA 1994; WVDA
1994).
A limited amount of data are also available from a 1992 survey of beef cattle
farms performed by the Beaver Valley Nuclear Power Station located in
Shippingport, Pennsylvania, approximately 10 miles east of the WTI facility (PCI
1992). Data were collected over a 5-mile radius centered at the power station.
The survey indicates that within five miles of the Beaver Valley Power Station at
the time of the survey, there were 67 farms with a total of 909 beef cattle, as
indicated in Table Vn-7. These data are presented in Figure Vn-1.
Based on the site-specific data obtained, it is estimated that the residents in
the vicinity of WTI obtain 15 percent of their beef diet from locally raised
livestock. Site-specific data are also used to develop estimates of the fraction of
residents' pork and egg diet that is from locally raised livestock, as described in
Appendix V-8.
b. Dairy Fanning
The number of milk cows, milk production, and milk marketing data
available from the Agricultural Statistics Services for Ohio, Pennsylvania, and
West Virginia (ODA 1994; PDA 1994; WVDA 1994) are summarized in Table
vn-8. To augment these data, agricultural extension agents representing counties
in the vicinity of the WTI facility were contacted to provide a local
characterization of dairy farming practices (personal communication, county
agricultural extension agents, August 1994). In general, the extension agents

reported that dairy farming in the eastern Ohio/western Pennsylvania area is not
significantly different from other parts of Ohio and Pennsylvania, and that state-
wide statistics are likely applicable to the area around the WTI facility. Table
Vn-9 provides estimates of county-specific milk cow herd size and milk
production statistics, and estimates of milk marketing, based on the state-wide data
for three counties in the vicinity of the WTI facility. The milk marketing data
include.information on milk consumption on the farm, marketing to plants/dealers,
and direct sales to consumers.
With respect to the milk marketing data, it should be noted that Ohio and
West Virginia do not differentiate between milk sold to plants/dealers and milk
sold directly to the consumer. The distribution between these two options shown
in the Pennsylvania data, therefore, is applied to the Ohio and West Virginia data.
This estimate was carried through to the estimates of county-level milk marketing.
It is estimated that this assumption does not significantly affect estimates of total
local milk available in Ohio and West Virginia. Based on the data obtained from
the Agricultural Statistics Services, an estimate of the fraction of milk consumption
that is from local sources is derived. A value of 36 percent is estimated as
described in Appendix V-9.
As noted with the beef farming data, limited dairy farming data are also
available from a survey of dairy farms performed by the Beaver Valley Nuclear
Power Station. Data were collected over a 5-mile radius centered at the power
station and are summarized in Table VTI-10. The survey indicates that within five
miles of the Beaver Valley Power Station at the time of the survey, there were 332
dairy cows, of which 242 were milked. The total daily milk production for the
area is 970 gallons (4.0 gallons/cow). Although these data are not used to
estimate local milk consumption, a plot of the locations of these farms, shown in
Figure VTI-1, indicates that several large dairy farms are located in the vicinity of
the WTI facility (Figure VII-1 indicates the boundaries of the risk assessment
study area developed in Section D of this chapter).
General locations of dairy farms in the area surrounding the WTI facility are
based on information from the Agricultural Marketing Service of the USDA
(personal communication, J. Rourke 1994). These data provide information on the
number and size of dairy farms per ZIP code area in each of the counties
surrounding the WTI facility for a single month, May 1994. The data for the
three counties surrounding the facility are tabulated in Appendix V-10 and
summarized in Table VII-11. Figure VTI-2 shows the number of dairy farms by
ZIP code for several counties in the area of the WTI facility. Although these data

-------
provide useful information concerning the location of dairy farms in the vicinity of
WTI, annual data (Table VQ-9) are used to develop estimates of local milk
production because production rates can vary considerably throughout the year.
It should be noted that Figure VH-2, developed from the May 1994 data,
shows that many of the farms in Columbiana County are located in the northwest
portion of the county and very few farms are located in the area immediately
surrounding the facility. This information indicates that using county-wide data
and assuming that dairy farms are equally distributed across the county
overestimates risk (i.e., production of milk in the area that might be impacted by
the facility is lower than assumed).
4. Deer Hunting
The Departments of Natural Resources in Ohio, Pennsylvania, and West Virginia
were contacted for information on deer hunting in the area surrounding the WTI facility
(personal communication, ODNR 1994b; PDNR 1994; WVDNR 1995). These agencies
provided data as summarized in Table Vn-12. In addition, these agencies provided data
on the number of hunting licenses issued in Ohio, Pennsylvania, and West Virginia
counties, also summarized hi Table 33 in Appendix V-8. These data are used to
estimate typical deer meat consumption rates for deer hunters, as described in Appendix
V-8.
5. Population Data
Population data for the three-county (Columbiana, Ohio; Beaver, Pennsylvania;
Hancock, West Virginia) area surrounding the WTI facility are compiled from a
summary of the 1990 census developed by CACI Marketing, Inc. (CACI 1992), as
shown in Table vn-13. In addition, the county farming populations are estimated based
on the number of farms (USDC 1993a,b,c) and the typical household size (CACI 1992)
in each county.
D. Development of the Risk Assessment Study Area and Subareas
In this risk assessment, population risk, generally defined as the cancer risk burden
across all exposed individuals, is also evaluated. To facilitate the estimation of population
risks, exposure (and subsequently risks) is estimated for subgroups located in defined
subareas surrounding the WTI facility. These subareas are developed in order to account for
differences in exposure at different distances and directions from the facility. Because risk
generally decreases with distance from the facility, a point is eventually reached where
inclusion of additional individuals does not significantly affect total population risk (due to
External Review Draft
Volume V VH-16 Do Not Cite or Quote
-------
the insignificant increment in exposure of these individuals). The area within which the
population risk is estimated is referred to as the risk assessment study area. Outside this
area, risks are anticipated to be relatively insignificant. The methods used to develop the
risk assessment study area and the subareas within the study area are described below,
followed by an estimation of exposure in the subareas.
1. Development of the Risk Assessment Study Area
The area within which exposure (and risk) are estimated is referred to as the risk
assessment study area. The study area is defined so as to include all individuals that
may significantly contribute to the risk burden of the population in the vicinity of the
WTI facility. To ensure that all such individuals are included, the perimeter of the
study area is defined based on the risk to the most highly exposed subgroup within the
exposed population. Specifically, in this assessment, the study area is initially defined
based on an estimation of the human health risks associated with the accumulation of
chlorinated dioxin and furan compounds in locally raised beef, and subsequent ingestion
by a subsistence farmer. This exposure pathway and population subgroup were
identified in screening-level assessments performed by U.S. EPA as potentially the most
significant for the WTI facility (U.S. EPA 1993d, 1994g). Furthermore, the perimeter
of the study area is defined to include locations where excess cancer risks to a
subsistence farmer due to beef ingestion are estimated to exceed one in ten million (1 x
10~7). This level of risk was selected because risks less than 1 x KX6 have typically
been considered not to be subject to regulatory action by U.S. EPA. An individual risk
level below 1 x 10"7 would not likely contribute significantly to the overall risk burden
of the exposed population living closer to the facility.
To understand the relationship between the concentration/deposition predictions of
the air dispersion modeling and the estimated risks of dioxins, a preliminary analysis of
dioxin/furan cancer risk to a subsistence farmer was conducted. In the preliminary
analysis, the location of maximum impact of emissions from the WTI facility (indirect
and direct cancer risks should be greatest at this location) was used for this purpose.
Based on the air dispersion/deposition modeling conducted for the risk assessment, the
location of maximum impact is predicted to be approximately one kilometer east of the
WTI facility stack (as indicated in Volume IV). Based on the assumption that a
subsistence farm could be placed at this location, concentrations of dioxin/furan
congeners in beef were then calculated. These calculations were based on the fate and
transport models described in Chapter VI. Dioxin/furan cancer risks were subsequently
estimated by combining the exposure dose with toxicity values (Table ffl-1) for the
individual dioxin/furan congeners.
External Review Draft
Volume V VH-17 Do Not Cite or Quote
-------
As a result of this study area analysis, it was noted that plant uptake of vapor-
phase dioxin/furans is the primary contributor to total risk. By comparison, uptake of
dioxins/furans via particle deposition is relatively minor. For example, at the location
of maximum impact, the contribution of vapor-phase dioxins/furans to the total risk is
approximately two orders of magnitude greater than the contribution of either dry or
wet deposition (see Chapter VIE). Therefore, the predicted vapor concentrations of
dioxins/furans are used as a surrogate measure of total risk in this assessment.
The dioxin/furan cancer risk at the location of maximum vapor impact was
estimated in the study area analysis to be approximately 2 x Ifr6 (for beef ingestion by a
subsistence farmer). At the point of maximum impact, the air dispersion modeling
predicts a vapor impact of 0.91 /*g/m3 per gram/second emission rate from the stack
(i.e., the vapor impact of 0.91 ng/m3 per gram/second corresponds approximately to a
total dioxin/furan cancer risk of 2 x 10*). The perimeter of the study area used in this
risk assessment is defined to correspond to a total dioxin/furan cancer risk of 1 x Itt7, a
factor of 20 times lower than the estimated risk at the point of maximum impact.
Therefore, the perimeter of the study area corresponds to a vapor impact of 0.046
fig/m3 (0.91 pg/m3 per gram/second divided by 20), which is rounded to 0.05 ng/m3.
A plot of the vapor dispersion isopleths (shown in Appendix IV-1) predicted from the
air dispersion modeling indicates that the 0.05 /*g/m3 isopleth is irregular in shape but is
generally contained within a radius of 12 kilometers (km) of the site. The risk
assessment study area boundary, therefore, is defined by the 12-km radius.
2. Development of Subareas
The study area is divided into subareas to estimate risks to population subgroups
within the study area, and to facilitate the estimation of population risks. Based on the
results of the vapor dispersion modeling, 12 subareas are developed, as shown in Figure
VII-3. The boundaries of the subareas are defined by concentric rings surrounding the
facility at radii of 3 km, 7 km, and 12 km, and radials oriented northeast, southeast,
southwest, and northwest. The radials are oriented in this manner to include areas with
similar dispersion patterns within individual sectors. As developed, the average vapor
concentration in each subarea decreases approximately two to three fold from the
preceding subarea as the distance from the facility increases in any given direction.
Thus, average risks in the outermost sector are approximately an order of magnitude
less than the innermost sector in each direction.

3. Development of Subareas for Assessment of Fugitive Emissions
Although population risks are not being evaluated in the assessment of fugitive
organic vapor emissions from WT1, it is necessary to identify areas in the vicinity of
the facility where impacts are predicted to be most significant. Because the fugitive
emission sources at the WTI facility (with the exception of the CAB system stack) are
ground-level (or near ground-level) sources, the maximum predicted impacts from these
sources are generally on-site, with concentrations decreasing rapidly with distance from
the source. Thus, the area of interest for assessing the risks associated with fugitive
emissions is the immediate vicinity of the site.
The off-site impact of fugitive emissions is assessed within a 2,000-foot radius of
the site. This area is selected to include residential and commercial areas in East
Liverpool near the facility, and the East Elementary school. Based on a review of the
air dispersion modeling, predicted air concentrations decrease significantly at distances
greater than 2,000 feet from the facility. To account for concentration variation with
direction from the site, the 2,000-foot radius for the fugitive emissions study area is
sub-divided into four quadrants (north, south, east, and west), as indicated in
Figure VH-4.
£. Estimation of Exposure Doses in Subareas
1. Estimation of Contaminant Dispersion/Deposition in Subareas
In order to estimate the range of risks within a subarea, average exposure for the
entire subarea as well as exposure at the location of maximum impact are estimated.
The average risk of the population within a subarea is represented by the average or
typical estimate of exposure. To estimate typical exposure, the average concentration
and deposition rate of contaminants within the subarea is estimated. The air
dispersion/deposition modeling predicts air concentrations and particle deposition rates
(wet and dry) at discrete locations (referred to as receptor locations) on concentric
circles around the facility to a distance of 50 kilometers from the facility. Thus, each
of the 12 subareas (4 subareas for the fugitive emissions assessment) includes a number
of these discrete receptor locations: In the subareas closest to the facility (El, SI, Wl,
and Nl in Figure VII-3), where there is greater variation in predicted impacts, the
receptor locations are more closely spaced than farther from the facility, as described in
Volume IV. As a result, a greater number of receptors are contained within the
subareas closer to the facility. The average dispersion/deposition for a subarea is
estimated based on an area-weighted average of the dispersion or deposition predictions
at receptors within the subarea.

Volume V VH-19 Do Not Cite or Quote
-------
The calculated average dispersion and wet and dry deposition factors (surface and
mass-weighted) for each subarea are summarized in Tables vn-14 to Vn-17. In
addition, dispersion and deposition factors at the point of maximum impact in each
subarea (defined as the location of maximum predicted vapor concentration) are
compiled from the air dispersion/deposition modeling results and are summarized in
Tables VH-14 to VH-17.
2. Estimation of Exposure Dose
The predicted dispersion and deposition factors summarized in Table VII-14 to
vn-17 are used in the fate and transport models described in Chapter VI to predict
contaminant media concentrations in each of the subareas. Estimated media
concentrations in each of the subareas are summarized in Appendix V-l 1. The average
or typical exposure dose is calculated using the dose equations (LADD and ADD),
described earlier in this chapter. The dose equations use the media concentrations in
Appendix V-ll and the appropriate exposure factors in Appendix V-8. Typical
exposure doses for each subgroup of the population and for each exposure pathway are
shown in Appendix V-12. In addition, LADDs and ADDs for the exposed population
subgroups are estimated at the location of maximum impact within each subarea, as
shown in Appendix V-13. An example of estimated chemical-specific exposure doses
(LADDs and ADDs) is provided in Tables VII-18 and VII-19, for a subsistence farmer
in subarea El.
F. Uncertainties
In conducting the exposure assessment, several assumptions about general characteristics
of the population and individual behavior patterns are made. General characteristics of the
population include the identification of different subgroups that constitute the population in
the vicinity of the site. A detailed review is conducted to ensure that the general population
is represented; in addition, subgroups that could be subject to high exposure because of their
particular behavior patterns are identified. Although all populations may not be represented
in the analysis, the range of exposures that is evaluated is selected to constitute such a wide
range that exposures to a particular subgroup are likely to be represented within the exposure
range evaluated. Similarly, the exposure pathways are selected to be as inclusive as feasible,
so that it is unlikely that any pathway of significance is excluded.
In estimating the exposure dose for the exposed population, several exposure factors
such as inhalation rate, soil ingestion rate and body weight are used. Typical values for
these parameters are used in the analysis. To account for the variability in these factors, the
90th percentile values for each of the exposure factors are determined, as summarized in
External Review Draft
Volume V VII-20 DO Not Cite or Quote
-------
Appendix V-8. These high-end values are used in characterizing exposure to populations at
the high-end of the risk distribution in assessing exposure variability in Chapter VTQ. In
addition, in Chapter DC a quantitative evaluation of uncertainty and variability is conducted,
which relies on the range of values developed for the exposure factors in assessing the
overall impact of uncertainty and variability on the estimated risks at the site.
Specific assumptions used in the estimation of exposure dose are identified in
Table vn-20. This table summarizes the key assumptions, a basis for each assumption, and
the effect of each assumption of the results of the HHRA. The effect of each assumption on
the estimated risks is characterized by estimating the direction (under- or overestimate) and
relative magnitude (low, medium, high) of the effect. As shown in Table VII-20, the
selection of exposure factor values (especially for the subsistence farmer) likely has the
greatest effect of the assumptions used in this chapter.

Note:
a - Organic compounds adsorb onto the outer surface of airborne particles as condensation occurs in the cooler regions of
the post-combustion zone (i.e., surface distribution). Metals are assumed to be homogeneously dispersed throughout
the entire particle (i.e., mass distribution) because they may form particles themselves rather than condensing onto
existing particles. Therefore, for organics, deposition on particles is a function of die total surface area of panicles
emitted from the stack; whereas, for metals, deposition is a function of the total mass. The amount of a substance
deposited on the ground surface is dependent upon the type of distribution (surface or mass) assumed.

. RISK CHARACTERIZATION
A. Introduction
In the risk characterization step of the risk assessment process, the chemical
toxicity values (summarized hi Chapter IE) are combined with dose estimates for each of
the various exposure pathways and population subgroups (described in Chapter VII) to
evaluate both carcinogenic risks and the potential for noncarcinogenic health effects.
Beyond the quantitative aspects of the risk assessment, risk characterization is also
intended to place the estimated risks hi context through a discussion of the qualitative
elements of the risk assessment, including a discussion of the major factors influencing the
risk estimates, underlying assumptions, and the rationale for these assumptions. In
addition, the risk characterization generally includes a discussion of the uncertainty and
variability associated with the quantitative results. Therefore, a table of the key
assumptions, as described hi Volume n, is presented as part of the uncertainty section of
this chapter. A quantitative analysis of uncertainties is presented hi Chapter IX.
Based on a review of the Project Plan for the WTI Risk Assessment (U.S. EPA
1993b), the Peer Review Panel made several recommendations regarding risk
characterization. These recommendations include the following:
• Assessment of Risks Associated with Fugitive Emissions - The Project Plan (U.S.
EPA 1993b) proposed that fugitive emissions be evaluated on a qualitative level.
Based on recommendations of the Peer Review Panel, a quantitative analysis of
carcinogenic risks and the potential for noncancer health effects is conducted for
four sources of possible fugitive emissions from the WTI facility. This chapter
summarizes the results of the fugitive emissions analysis, which focuses on
exposures within 2,000 feet of the WTI facility where potential impacts are most
significant based on the air dispersion modeling.
• Additivitv of Risk - The Peer Review Panel commented that additivity of risks
should be considered hi the risk characterization, including an evaluation of
synergistic and antagonistic effects of exposure to chemicals hi combination. In
this chapter, additive risks are estimated for the combination of all chemicals
evaluated in each exposure pathway, and for the combination of all pathways

-------
evaluated for each population subgroup. A quantitative evaluation of synergistic
and antagonistic effects is not performed due to limitations in available data and
methodologies for characterizing or quantifying these effects at the exposure levels
estimated in the vicinity of WTI.
• Evaluation of Additional High-end Subgroups - The Peer Review Panel identified a
number of additional subgroups of the exposed population that may be at a higher
risk due to behavior patterns, proximity to the facility, or lexicological sensitivity.
An evaluation of additional high-end subgroups is presented hi Appendix V-5.
Based on this analysis, an additional potential high-end subgroup, deer hunters,
was identified. An evaluation of human health risks associated with consumption
of deer meat obtained from the vicinity of the WTI facility is presented in this
chapter.
• Uncertainty and Variability - The Peer Review Panel recommended that as part of
the characterization of risks, the uncertainty and variability associated with
estimated risks also be presented. A quantitative uncertainty and variability
analysis for the HHRA, is presented as a separate chapter (Chapter IX). Issues
that affect the uncertainty of the risk characterization are discussed qualitatively in
Section F of this chapter.
The following sections present the results of the risk assessment for exposure to
stack emissions and fugitive releases. Risks associated with exposure to stack emissions
and fugitive emissions are characterized separately.
B. Estimation of Risks Due to Stack Emissions
Substances of potential concern emitted from the incinerator stack at the WTI
facility disperse in the atmosphere as well as deposit on soils in the vicinity of the facility.
Exposure to these substances by individuals living and working in the area surrounding
the WTI facility can occur through various pathways and may result in adverse health
effects. To estimate the likelihood of such effects, cancer risks and the potential for
noncarcinogenic effects are characterized based on a combination of estimated exposure
doses and U.S. EPA-published chemical-specific toxicity values, as described below.
1. Methodology for Estimating Individual Cancer Risk
The excess lifetime cancer risk resulting from the modeled exposure to a
specific carcinogenic chemical is calculated by multiplying the lifetime average daily

-------
dose (LADD), which is estimated as described in Chapter YE, by the risk per unit
dose, or slope factor (discussed in Chapter HI), as follows:
Risk, = (LADDjXSFj) (VIII-1)
where:
Riskj =:= lifetime probability of developing cancer due to
exposure to chemical i in stack emissions from the
WTI facility
LADDj = lifetime average daily dose to chemical i, mg/kg-day
SFj = carcinogenic slope factor for chemical i, (mg/kg-day)"1
In cases of multiple chemical exposures, it is assumed that cancer risks are
additive (U.S. EPA 1986b). Accordingly, the cancer risk estimates for each
exposure pathway are developed by summing the risk calculated for the individual
chemicals. In addition, risk estimates are summed across exposure pathways to
develop total cumulative risks for a population subgroup, in cases when it is
reasonable to assume that individuals hi a subgroup could typically be exposed
through all such pathways.
2. Methodology for Estimating Individual Noncancer Effects
Unlike the measure of risk used for carcinogens, the measure used to
describe the potential for noncarcinogenic effects to occur is not expressed as a
probability of experiencing an adverse effect (U.S. EPA 1986b). Instead, the
potential for adverse noncancer effects is expressed as the ratio of the calculated
dose to the dose below which adverse effects are not anticipated (or the Reference
Dose). If this ratio exceeds 1.0 (unity), it is assumed that the potential exists for
noncancer health effects. For oral exposures, the following equation is used:
HQi = ADD/RfD, (VIII-2)
where:
= hazard quotient for chemical i
ADD = average daily dose to chemical i (all appropriate pathways
combined), mg/kg-day
RfD = reference dose for chemical i, mg/kg-day
External Review Draft
Volume V Vffl-3 Do Not Cite or Quote
-------
For inhalation exposures, reference air concentrations (RACs), which
account for exposure to background sources of chemicals with noncarcinogenic
effects, are developed to assess the potential for noncancer effects. In order to
compare the RACs, expressed in units of milligrams per cubic meter (mg/m3), with
the ADD, the RACs are converted to inhalation reference doses, in units of
milligram per kilogram-day (mg/kg-day), based on a standard inhalation rate (20
mVday) and body weight (70 kilograms) (U.S. EPA 1990b). The hazard
quotients are calculated using the above equation and the inhalation RfDs.
The assessment of overall potential for noncancer effects posed by
simultaneous exposure to multiple chemicals is conducted using the Hazard Index
approach developed in U.S. EPA's Guidelines for the Health Risk Assessment of
Chemical Mixtures (U.S. EPA 1986b) and described in U.S. EPA's Risk Assessment
Guidancefor Superfund (U.S. EPA 1989b). As a first screening, the HQ values for
all individual chemicals associated with a given exposure pathway are summed to
provide an indication of the potential for noncancer effects posed by multiple
chemical exposure. This sum of the HQ values for individual chemicals is referred
to as the Hazard Index (HI). The HI approach assumes that multiple sub-
threshold exposures could result in an adverse effect, and that a reasonable
criterion for evaluating the potential adverse effects is the sum of the HQ values
(U.S. EPA 1986b). In cases where the overall HI exceed unity, chemicals are
segregated by target organ effect and mechanism of toxicity to derive HI values for
each type of effect, as recommended by U.S. EPA (1986b).
3. Methodology for Estimating Population Cancer Risk
In addition to individual risk, the total cancer risk burden for the exposed
population in the vicinity of the facility is determined for incinerator stack
emissions.1 As described in Chapter VII, a study area has been developed
comprising of 12 subareas surrounding the WTI facility. Cancer risks for each of
the identified subgroups (e.g., farmers, adult residents, child residents, etc.) are
estimated within each subarea using the procedures described above. The total
population cancer risk associated with incinerator stack emissions is then calculated
across all subareas and subgroups in the study area using the following equation:
1 Given the relatively small area potentially affected by fugitive emissions based on the
atmospheric dispersion modeling, population risks are not characterized for fugitive
emissions sources.

Population Cancer Risk =
where:
Py = population of subgroup i in subarea j
Risky = cancer risk for subgroup i in subarea j
. n = number of subgroups
m = number of subareas
The calculated population cancer risk represents the hypothetical number of
additional cancer cases within the study area due to stack emissions at the WTI
facility, given the assumptions inherent in the calculation of individual risk.
C. Overview of Individual Risks Associated with Stack Gas Emissions
Using the methodologies described above, excess cancer risks and HQ values are
estimated for the following major population subgroups:
• Adult non-farming resident;
• Child non-farming resident;
• Adult farmer; and
• Child of farmer.
In addition to these major subgroups, which are expected to comprise a significant
portion of the local population, three subgroups of the population, which may
experience elevated exposures due to their particular behavior patterns also identified:
• School-age child resident;
• Adult subsistence farmer; and
• Child of subsistence farmer.
For each of the two sets of subgroups listed above, inhalation cancer risks and
noncancer HQ values are estimated for more than 200 substances of potential concern in
each of the 12 subareas. For the indirect pathways of exposure, excess cancer risks and
noncancer HQ values are estimated for the substances of primary concern, which include
metals, dioxin/furan congeners, organic chemical residues and PICs with the greatest
potential to accumulate in the food chain.
External Review Draft
Volume V Vni-5 Do Not Cite or Quote
-------
In addition to these subgroups, excess cancer risks and noncancer HQ values are
estimated for the following four activities that may lead to significantly higher exposures,
but in which only a relatively small fraction of the population is expected to participate:
• Consumption of locally caught fish by a subsistence fisherman;
• Consumption of deer harvested locally by hunters;
• Consumption of mother's milk by breast-feeding infants; and
• Consumption of homegrown fruits and vegetables from residential gardens.
The risks associated with direct and indirect exposures by the seven population
subgroups are discussed below. Calculated risks are presented only for average emission
rates for the substances of concern, and "average" or "typical" exposure factors, as
discussed in Chapter VII. For each subarea, risks posed by average and maximum
concentrations, as differentiated by the atmospheric dispersion modeling of average
emission rates, are presented. Following the discussion of direct and indirect risks based
on average emissions and typical exposure, the results of a sensitivity analysis on the
exposure factors are presented. The impact of using high-end emission rates is evaluated
in Chapter IX.
Results are also presented for an analysis of the potential effects of lead emissions
from the incinerator, and the risks posed by the four activities identified above as
potentially leading to higher exposures (i.e., ingestion of fish by a subsistence fisherman,
ingestion of deer hunted locally, consumption of mother's milk by an infant, and
consumption of homegrown vegetables).
1. Individual Risks Due to Direct (Inhalation) Exposure
For the inhalation pathway, excess cancer risks and noncancer HQ values
are estimated for the substances of potential concern for stack gas emissions,
including organic compounds and PICs, dioxin and furan congeners, metals, and
hydrochloric acid (HC1). Nitrogen oxides (NOX), sulfur oxides (SOJ, and particles
are examined by comparison to the National Ambient Air Quality Standards
(NAAQS). Cancer risks and noncancer HQ values for the inhalation pathway are
estimated based on: 1) the average vapor concentration calculated within each
subarea; and 2) the maximum calculated vapor concentration in each subarea.
a. Carcinogenic Effects
Table VIII-1 summarizes the estimated total inhalation cancer risks
for the substances of potential concern for each subarea. Area average

Volume V Vm-6 Do Not Cite or Quote
-------
inhalation cancer risks are based on average air concentrations estimated in
each subarea, as described in Chapter VII. In addition, excess cancer risks
at the point of maximum vapor concentration in each subarea are also
presented. As shown in Table Vni-1, estimated average cancer risks do not
exceed 1 x 10~7 for any population subgroup in any subarea. The highest
inhalation cancer risk,
8 x 10~8, (assuming average concentrations) is for children of residents and
farmers living in subarea El. Inhalation cancer risks in subarea Wl are
approximately 30 percent lower than estimated average risks in subarea El.
Average cancer risks in subareas SI and Nl for all subgroups are
approximately half those estimated in subarea El.
As evident from Table VIII-1, cancer risks tend to decrease with
increasing distance from the facility. In general, risks decrease by a factor of
2 to 3 from subarea to subarea as the distance from the site increases in any
one direction (e.g., El to E2 or E2 to E3).
Cancer risks estimated at the point of maximum concentration
follow a similar pattern to that described above, but are generally a factor of
2 to 4 higher than estimated average cancer risks. The highest estimated
cancer risk, 2 x 10~7, is for children of residents and farmers living in subarea
El at the point of maximum concentration. Appendix V-14 presents the
inhalation cancer risks for individual substances of potential concern.
b. Noncarcinogenic Effects
Table VIII-2 summarizes HI values estimated for the substances of
potential concern, based on the estimated air concentrations in each
subarea. As shown in Table VIII-2, estimated total HI values do not
exceed 1.0 (unity), indicating that adverse noncancef human health effects
are not expected to occur due to inhalation exposure. Similar to the
pattern of average cancer risks described above, the potential for noncancer
health effects is greatest in subarea El followed by subarea Wl. HI values
hi other subareas are significantly lower than values estimated for subarea
El, and tend to decrease with increasing distance from the facility. HI
values are highest for children of residents and farmers, but do not exceed 5
x 10'2 based on average concentrations within subarea El.
HI values are estimated to be 2 to 4 tunes higher at the point of
maximum concentration than HI values based on the areal average
concentration. HI values for children of residents and fanners in subarea

El are 1 x 10"1 based on maximum estimated concentrations in subarea El.
HI values in other subareas based on maximum estimated concentrations
do not exceed 1 x 10"1 for any subgroup. Appendix V-14 contains
inhalation HQ values for the substances of potential concern considered in
this assessment.
c. Potential Health Effects Associated with Inhalation of NOX,
SOX, and Particulate Matter
Chronic toxicity criteria have not been established by U.S. EPA for
SOX, NOX, or particles less than 10 microns hi diameter (PMi0). Thus, an
evaluation of the risks posed by emissions of these substances is performed
by comparison to annual average National Ambient Air Quality Standards
(NAAQS). U.S. EPA has developed annual average NAAQS values for
NO2, SO2, and PM10 of 100, 80, and 50 ng/m3, respectively. The
maximum and average ground-level air concentrations of these substances
estimated in each subarea are presented hi Table Vffl-3. As shown hi
Table VHI-3, the average predicted concentrations of SOX, NOX, and PM10
hi the subareas are at least 100 tunes less than the NAAQS, with maximum
predicted concentrations at least a factor of 10 below the NAAQS hi all
subareas. The highest estimated concentrations of SOX, NOX, and PM10
within a single subarea are predicted to occur hi subarea El. Using the
NAAQS as a guideline, inhalation exposure to SOX, NOX, and PM10
emissions from the WTI facility stack is, therefore, not expected to pose a
significant health risk.
2. Risks Due to Indirect Exposure
For the indirect routes of exposure, average and maximum excess cancer
risks and noncancer HQ values are estimated for the dioxin/furan congeners,
metals, and other surrogate organic chemicals. Average risk estimates are based on
average emission rates, average dispersion/deposition within a subarea, and typical
exposure factors. Maximum risks are also estimated using average emission rates
and typical exposure factors, but are estimated at the point of maximum vapor
concentration (based on air dispersion modeling) within a subarea.
As described hi Chapter IV, a screening process was developed to identify
the organic residues and PICs that represent the greatest potential health hazard
through the indirect exposure pathways. For each of the surrogate chemicals
identified to be of primary concern (including dioxin/furan congeners, metals, and
External Review Draft
Volume V Vffl-8 Do Not Cite or Quote
-------
organic residues and PICs), cancer risks and/or noncancer HQs are estimated for
the following exposure pathways:
• Soil ingestion;
• Dermal contact with soil;
• Consumption of meat (beef, pork, and poultry) and eggs from
locally raised livestock;
• Consumption of milk and dairy products (cheese, milk desserts,
yogurt, cream, and butter) from locally raised cows;
• Consumption of homegrown fruits and vegetables;
• Ingestion of river/lake water during swimming; and
• Dermal contact with river/lake water during swimming.
The pathways of exposure applicable to the individual subgroups were identified
earlier hi Table V-l.
Tables VIII-4 and VIII-5 summarize the estimated total cancer risks and
noncancer hazard indices for the seven population subgroups in the subareas
designated. The average cancer risks and hazard indices are based on media
concentrations estimated from average emission rates and average contaminant
deposition within each subarea. Cancer risks and HI values for the location of
maximum exposure in each subarea are also presented hi Tables VIII-4 and VIII-5.
Estimated cancer risks do not exceed 1 x 10~5 for any population subgroup.
Estimated HI values are at least an order of magnitude below unity for exposure
under both average and maximum concentration conditions. As shown in Tables
VIII-4 and VIII-5, the subsistence farmer and child population subgroups have
the highest cancer risk and HI values. In subarea El, where the highest risks are
predicted, cancer risks to the subsistence fanner and child are 1 x 10"* (for both
subgroups), based on average concentrations within the subarea. Average cancer
risks for other subgroups do not exceed 5 x 10"7. Cancer risks at the location of
maximum concentration in subarea El are estimated to be 4 x 10"6 for the
subsistence farmer and child, and risks are generally 2 to 3 tunes greater than the
average estimated risks. Cancer risks do not exceed 2 x 10"6 for the resident,
farmer, and school child subgroups.
HI values are also estimated to be highest in subarea El, with subarea Wl
somewhat lower (approximately 30 percent). HI values in subarea El based on
average and maximum concentrations do not exceed 2 x 10"2 and 6 x 10"2,
respectively, for the child of a subsistence farmer. For other subgroups, estimated
External Review Draft
Volume V VHI-9 Do Not Cite or Quote
-------
HI values, based on average and maximum concentrations, do not exceed 9 x 10~3
and 2 x 10~2, respectively. Appendix V-15 contains cancer risks and HQ values for
the individual substances of primary concern estimated for the indirect exposure
pathways that are considered in this assessment.2
Tables Vni-6 and Vffl-7 provide risk estimates for individual exposure
pathways for the subsistence farmer (exposure pathway-specific cancer risks and HI
values for the .other population subgroups are provided in Appendix V-16). As
Tables VIII-6 and VIII-7 show, consumption of food (i.e., ingestion of meat and
eggs from locally raised livestock, consumption of milk and dairy products from
locally raised cows, and consumption of homegrown fruits and vegetables) is the
most significant exposure pathway for the subsistence farmer. The distribution of
risks between the various food pathways varies somewhat between subgroups, due
to varying consumption rates between subgroups (e.g., dairy products
consumption accounts for a greater proportion of the total risk for children than
for adults due to significantly higher milk consumption rates in children), as
shown in Appendix V-16. Risks from non-food exposure pathways (soil and
surface water related pathways), however, are relatively insignificant.
Tables VIII-8 and VIII-9 present chemical-specific cancer risks and
noncancer HQ values for the adult subsistence farmer in subarea El. The most
important contributors to total cancer risk are the dioxin and furans congeners
(accounting for 76 percent of the total cancer risk for the subsistence farmer in
subarea El). In particular, 2,3,4,7,8-pentachlorodibenzofuran (2,3,4,7,8-PeCDF)
accounts for 38 percent of the cancer risk for a subsistence farmer in subarea El.
Organic compounds account for the greatest portion of the total HI (71 percent)
with hexachlorophene accounting for 38 percent of the total HI value. The
metals with the greatest contribution to the total HI are thallium and mercury,
together accounting for almost 90 percent of the total HI for inorganic
2 As noted in Chapter VII, upon estimation of the cancer risks and noncancer HI values,
an adjustment to the study area boundary would be made if it appeared that the boundary of
the preliminarily defined study area did not include all areas of potentially significant risk.
However, as apparent from a review of the cumulative human health risks estimated in the
subareas on the outer ring of the study area (i.e., subareas E3, S3, W3, and N3), the area
outside the designated study area is expected to be very low risk (i.e., less than a 1 x 10"7
cancer risk or His less than 0.1) for all population subgroups. The study area and the
subareas within the study area, as defined in Chapter VII, therefore, are assumed to include
all areas of significant risk.

-------
compounds, and 15 and 13 percent, respectively, of the total HI for all
compounds.
Tables VTTI-10 and Vni-11 present the combined direct and indirect cancer
risks (sum of values in Tables Vffl-1 and Vm-4) and HI values (sum of values in
Tables Vffl-2 and Vni-5), respectively. Total cancer risks and HI values are
greatest in subarea El, with the highest risk experienced by adult subsistence
fanners and children of subsistence farmers.
3. Sensitivity Analysis of Exposure Parameters for the Highly Exposed
Subgroups
Exposure parameters (e.g., ingestion rate, inhalation rate, exposure
frequency) are used in the exposure assessment process to reflect the behavior and
activity patterns of the population subgroups. The values of these exposure
parameters are often based on the assumption that the exposed population or
subgroup is homogeneous. In reality, however, the exposed population actually
consists of many individuals, with a distribution of exposures due to varying
inhalation rates, ingestion rates, exposure durations and other critical behavioral
characteristics.
To evaluate the variability in risks estimated for the most highly exposed
subgroups, the subsistence fanner and child hi subarea El (as noted above), the
exposure parameters (in Appendix V-8) that have the most significant impact on
the magnitude of potential exposures are identified and varied to determine "high-
end" risks. These parameters are identified by setting each parameter, in turn, at
the high-end value and calculating the resulting risks. The two parameters that
result in the greatest increase in exposure (and risk) are identified for each exposure
pathway. Using the identified parameters, high-end exposure and the associated
risk are estimated.
For example, for food consumption pathways, assuming that the body
weight and lifetime are constants, the lifetime average daily dose through each
food pathway is estimated varying each of the following parameters:
CM: Chemical Concentration hi Food (related to emission rate)
IR: Food Ingestion Rate
FI: Fraction Ingested from Contaminated Source
EF: Exposure Frequency
ED: Exposure Duration
External Review Draft
Volume V VHI-11 Do Not Cite or Quote
-------
For the adult subsistence farmer, the exposure parameters with the greatest effect
on total risk are food ingestion rates and exposure duration. For the subsistence
farmer child, the exposure parameters with the greatest effect on total risk are food
ingestion rates and concentration in food (estimated based on the variability hi the
emission rates). Risks are thus re-calculated with these parameters set at the high-
end value and all the other parameters set at their typical values. The resulting
risk estimates represent the upper end of the risk distribution for the adult and
child subsistence fanner exposure population subgroups in subarea El, the most
highly exposed subgroups in the general population.
As shown hi Tables VIII-12 and Vin-13, high-end food consumption
cancer risks and hazard indices for the subsistence farmer and child are generally 2
to 6 times higher than average cancer risks and hazard indices. Total high-end
cancer risk (all exposure pathways combined) for the subsistence farmer and child
do not exceed 7 x 10"6, and the cumulative high-end noncancer hazard indices are
1 x 10"1 for the subsistence farmer child and 3 x 10~2 for the subsistence farmer.
Appendix V-17 provides details of the high-end cancer risks and hazard indices
estimated for the subsistence farmer and child hi subarea El.
4. Estimation of the Potential Health Effects Due to Lead
The evaluation of risks associated with exposure to lead requires the use of
U.S. EPA's Integrated Exposure Uptake Biokinetic (IEUBK) model for lead in
children, a computerized model that predicts blood lead concentrations hi children
exposed to lead through a variety of media. The model is designed to estimate
blood lead levels using a combination of default exposure assumptions and site-
specific exposure information, where available.
The assessment of risks associated with exposure to lead from the WTI
facility is conducted using version 0.99d of the IEUBK model, which is calibrated
for children from one-half to seven years of age (U.S. EPA 1994e). Uptake of
lead from five media (air, drinking water, soil/dust, food, and paint) is evaluated
by the model. For this assessment, blood lead levels for children in the one to
seven year-old age range are modeled.
The default input values used in the IEUBK model are presented in Table
VIII-14. Two site-specific exposure values (background lead concentrations hi air
and child inhalation rates) are substituted for the model default values for the WTI
site analysis. The default air lead concentration of 0.1 jig/m3 is replaced with an
estimated background air lead concentration of 0.065 /ig/m3 (OEPA 1993). This
concentration is estimated from air sampling conducted at the East Elementary
External Review Draft
Volume V VTn-12 Do Not Cite or Quote
-------
School in East Liverpool, which was compiled by Ohio EPA. Monthly samples
were collected from this monitoring station during late-1992 and early 1993, prior
to full operation of the WTI facility. None of the samples indicated the presence
of lead in air above the detection limit (which ranged from 0.075 to 0.188 jig/m3).
The lead concentration in air is estimated as the average of one-half the detection
limits for the seven monthly samples.
In addition, the default age-specific inhalation rates for one to seven year-
old children, which ranged from 2 to 7 m3/day, are changed to 16 m3/day for all
ages to be consistent with the inhalation rate for children used elsewhere in this
risk assessment. This change likely results in an overestimate of the potential for
adverse health effects in children due to inhalation of lead.
For all media modeled, site-specific incremental increases in lead
concentrations attributed to the WTI incinerator are added to the default values or
site-specific background lead concentrations. In all cases, however, the magnitude
of these incremental increases is too small to change the model inputs (i.e.,
modeled media lead concentrations due to the WTI facility are insignificant
compared to estimated background levels of lead in the environment).
According to U.S. EPA, the Food and Drug Administration (FDA), the
/— Centers for Disease Control (CDC), and other regulatory bodies, low-level
"v^ exposure to lead during infancy and childhood increases the risk of irreversible
neurobehavioral deficits at levels of internal exposure as low as 10 /ig/dL (CDC
1991; U.S. EPA 1990c, 1994e; USDHHS 1990; ATSDR 1993). In general,
regulatory agencies consider exposures that correspond to blood lead levels of 10
/zg/dL or less in 95 percent of exposed children to be acceptable. The Guidance
Manual for the IEUBK model (version 0.99d) for lead hi children (U.S. EPA
1994e) states:
"At present the definition of elevated blood lead (EBL) is the level
of concern of 10 ng/dL defined by U.S. EPA (1990g) as the lower
limit of the range of known possible adverse neurobehavioral effects
in young children. The protection level most often used in practice
is a maximum 5 percent risk of elevated blood lead (EBL) for
children in a given household."
This criterion is used in the WTI incinerator site analysis.
The output of the IEUBK model is a probability curve constructed around
a modeled geometric mean blood lead concentration. From this probability curve,
f " the 95th percentile of the children's blood lead concentrations can be determined

The probability curve from the WTI incinerator site analysis is shown in Figure
VIII-1. As is demonstrated by this probability curve, over 98% of the children
who may be exposed to lead in the environment from both background sources
and from the WTI facility are predicted to have blood lead levels below the 10
fjig/dL level. It should be noted that this percentage of children below 10 jicg/dL
remains unchanged whether or not the emissions from the WTI facility are
considered, since exposures to background levels of lead in air and soil far exceed
exposures specifically associated with operation of the WTI facility. This
observation indicates that lead emissions from the incinerator stack should have no
adverse impacts on local children and would not change the estimated number of
local children with elevated blood lead levels.
Because one to seven-year-old children are generally considered more
sensitive to lead exposure that older children or adults, further analysis of lead
exposure and potential health effects is not conducted.
5. Risks Associated with Specific Activities
As noted earlier, a limited number of individuals in the population may be
engaged in specific activities that may result in elevated risks (e.g., subsistence
fishing, deer hunting, home gardening, and consumption of mother's milk by an
infant). For some individuals, the risks estimated for these specific activities could
be an incremental addition to the risks associated with the exposure pathways
described earlier. Risks associated with the substances of primary concern
(including dioxin/furans, surrogate organic chemicals, and metals) through the
indirect exposure pathways are estimated for the populations described below.
a. Subsistence Fishing
As indicated in Chapter VII, an analysis of local fishing data indicate
that consumption of locally caught fish by the general residential
population is unlikely to be a significant source of exposures. However, it
is possible that a subgroup of the population may derive a significant
portion of their daily diet from locally caught fish (subsistence fishing).
Cancer risks and noncancer HQs are estimated for subsistence fishing based
on the estimated dose via fish ingestion for the substances of primary
concern. Table VIII-15 summarizes the total cancer risks and hazard
indices for each of the subareas. Average risks are estimated based on
average dispersion and deposition of contaminants within a subarea.
Chemical-specific cancer risks and HQ values are shown in Appendix V-18.

-------
In estimating cancer risks and noncancer HQs for subsistence fishing,
actual bodies of water in the vicinity of the WTI facility in which fishing
reportedly occurs are identified. Segments of the Ohio River (the largest
body of water in the vicinity of the facility and the one most frequently
used for fishing) are evaluated in each of the subareas through which it
passes. In addition, Little Beaver Creek, which is located hi Ohio near the
Ohio-Pennsylvania border (subarea N2), is evaluated because discussions
with local wildlife officials indicated that this body of water is a popular
fishing location. Finally, Tomlihson Run Lake, located approximately 6
miles south of the WTI facility hi West Virginia is also evaluated to include
a lake environment (i.e, the other water bodies are rivers or creeks).
Tomlinson Run Lake is located hi subarea S3.
As shown in Table Vm-15, subsistence consumption of fish from
recreational areas located in the vicinity of the WTI facility results in
incremental cancer risks of less than 6 x 10'8, with the highest risks due to
fishing hi the Ohio River. HI values are estimated to be significantly less
than 1.0 for all subareas where lakes or rivers are located. Estimated HI
values based on average concentrations do not exceed 4 x 10~3 (Tomlinson
Run Lake). Maximum concentration HI values are not estimated for
Tomlinson Run Lake because it is located several miles from the point of
maximum concentration. The estimated HI value for subsistence fishing in
the Ohio River at the location of maximum concentration is estimated to
be 2 x lO'3.
It should be noted that in the assessment, it is assumed that mercury
in aquatic environments is found as both inorganic mercury and
methylmercury, which fate and transport modeling indicates will
bioaccumulate to a greater degree than inorganic mercury. As noted in
Chapter VI, 25 percent of the mercury hi aquatic environments is estimated
to be hi the form of methylmercury. Chemical-specific risks associated with
aquatic exposure to inorganic mercury and methylmercury are tabulated in
Appendix V-18.
Due to the relatively insignificant risks associated with subsistence
fishing, total risks would not increase significantly for individuals
participating hi this activity.

b. Deer Hunting
Deer living in the vicinity of the WTI facility may be exposed to
contaminants released from the WTI facility stack. It is possible, therefore,
that individuals hunting in the area surrounding the WTI facility and
consuming deer meat may be indirectly exposed to substances released from
the WTI facility stack.
Deer meat concentrations are estimated in a fashion similar to that
used for beef concentrations, assuming the same biotransfer and
bioconcentration factors as for beef but using dry matter consumption rates
and fat contents that are specific for deer. Excess cancer risks and
noncancer HQs are estimated for the consumption of meat from deer
hunted hi the vicinity of the WTI facility. Table Vm-16 summarizes the
total cancer risks and hazard indices for each of the subareas. Average risks
are estimated based on average dispersion and "deposition of contaminants
within a subarea. In addition, cancer risks and hazard indices at the point
of maximum concentration within a subarea are also evaluated, and are
presented hi Table VIII-16. As shown in Table VIII-16, the incremental
average cancer risks do not exceed 1 x 10"8, and average HI values do not
exceed 5 x 10'5, for all subareas. Maximum cancer risks and HI values are
generally 2 to 3 tunes higher than average estimated risks. The highest
cancer risks and HI values for consumption of deer meat occur hi subarea
El. Cancer risks and HI values in subareas Wl, SI, and Nl are somewhat
lower (approximately 30 to 70 percent lower). It should be noted,
however, that it is unlikely that significant deer hunting occurs in the
subareas immediately surrounding the WTI facility due to the proximity of
developed areas. Farther away from the facility, where hunting is more
likely, risks tend to decrease by a factor of 2 to 3 (from subarea to subarea)
as the distance increases from the WTI facility. Chemical-specific cancer
risks and HQ values are shown in Appendix V-18.
c. Home Gardening
Some residents living in East Liverpool and surrounding areas have
home gardens from which they may consume fruits and vegetables. An
informal home gardening survey was conducted in June 1993 by the East
Liverpool Board of Health, as described hi Chapter VII. As a result of this
survey, the Board of Health estimated that approximately 30 percent of
local residents have home gardens. Therefore, excess cancer risks and
External Review Draft
Volume V VIII-16 Do Not Cite or Quote
-------
noncancer HQs due to exposure to stack gas constituents deposited on and
accumulated in homegrown fruits and vegetables are estimated for this
segment of the population.
Table Vffl-17 summarizes the total cancer risks and HI values for
each of the subareas. Average cancer risks and noncancer HI values are
estimated based on average dispersion and deposition of contaminants
within a subarea. In addition, cancer risks and noncancer HI values at the
point of maximum concentration within a subarea are also evaluated, as
shown in Table Vin-17. Average cancer risks for ingestion of homegrown
vegetables by residents with gardens are below 6 x 10"9 for all subareas and
the hazard indices do not exceed 1 x 10"*. Cancer risks and hazard indices
at the location of maximum concentration hi each of the subareas are 2 to
3 tunes higher than the average cancer risks and hazard indices.
It should be noted that this assessment is limited to the
consideration of fruits and vegetables from home gardens and does not
consider the consumption of locally raised produce by individuals without
home gardens. However, due to the low level of risk estimated, it is
unlikely that locally grown vegetables pose a significant health risk. In
addition, due to the relatively insignificant cancer risks and HI values
estimated for home gardening, risks associated with this activity will not
appreciably increase total risks to local residents.
d. Ingestion of Mother's Milk by Infant
Lipophilic compounds, such as dioxins and furans, may accumulate
hi body tissues and preferentially concentrate hi adipose tissue. Exposure to
these compounds by a mother before and while lactating, therefore, may
result hi the accumulation of contaminants in breast milk, and exposures to
breast-feeding infants during nursing.
Excess cancer risks are estimated for infants exposed to contaminants
accumulated in mother's milk. In calculating exposure levels for the infant
through breast milk ingestion, it is assumed that the mother receives
exposure through each of the pathways considered for a particular
subgroup. Table VIII-18 summarizes the total cancer risks for each of the
subareas. Average cancer risks are estimated based on average dispersion
and deposition of contaminants within a subarea. In addition, cancer risks
at the point of maximum concentration within a subarea are also evaluated,
as shown in Table VIII-18. It should be noted that noncancer health

-------
effects due to infant ingestion of breast milk are not considered in this
assessment due to the significant uncertainty in applying noncancer toxicity
data to infants (U.S. EPA 1994a).
Cancer risks based on average subarea exposures do not exceed 4 x
10'7 for infants of residents, 7 x 10~7 for children of fanners, and 2 x 10"6 for
children of subsistence farmers. These cancer risks are estimated for subarea
El; the subarea with the next highest average cancer risks is subarea Wl,
where estimated risks are approximately 30 percent lower than in subarea
El. The primary contributor to the estimated average cancer risk of the
infant of a subsistence farmer in subarea El are the non-dioxin organic
compounds (66 percent of total risk) with benzo(a)pyrene accounting for
37 percent of the total average cancer risk. Dioxin and furan congeners as a
whole account for 34 percent of the total estimated average cancer risk.
Chemical-specific cancer risks for the infant of a subsistence fanner in
subarea El are provided in Appendix V-15.
Cancer risks estimated for the point of maximum concentration in
each subarea are generally 2 to 3 times higher than the average risks.
Estimated maximum location cancer risks for breast-feeding infants of non-
farming residents are 1 x 10"6 in subarea El, the area of greatest impact,
while breast-feeding infants of farmers and subsistence farmers are 2 x 10"6
and 5 x 10~6, respectively, in subarea El.
D. Overview of Population Risks
Individual risks are estimated for several population subgroups in the 12 subareas
surrounding the WTI facility. These individual risks are combined with population data
for each subarea (and subgroup) to estimate the cancer risk burden for the population
within the study area. The population cancer risk is calculated as the individual cancer
risk for each member of a population subgroup multiplied by the number of individuals
in that population subgroup, summed across all subgroups.
Population data for ZIP codes contained partially or wholly within the study area
have been compiled (CACI 1991). The population within three age groups—infants (0 to
12 months), children (1 to 12 years), and adults (13 years and older)—is estimated for
each ZIP code area, and the fraction of each ZIP code area contained within each subarea
is estimated based on Figure VIII-2. Appendix V-19 summarizes the population data for
each ZIP code and the fraction of each ZIP code contained within each risk assessment
subarea. The product of the fraction of a ZIP code area contained within a subarea and
the ZIP code area population is used to estimate subarea populations. This methodology
External Review Draft
Volume V VIII-18 Do Not Cite or Quote
-------
assumes that the population within a ZIP code area is evenly distributed; therefore, the
population within some subareas may be underestimated while the population in others it
may be overestimated. This uncertainty, however, is not expected to impact significantly
the results of the population risk assessment.
The total population is divided into the fanning and the non-farming population.
Census data on the farming population in the area surrounding the WTI facility were not
readily available; therefore, the farming population is estimated. As indicated in Chapter
VII, the 1992 Agricultural Census (USDC 1993a,b,c) identifies the number of farms in
each of the three counties (Columbiana, Ohio; Beaver, Pennsylvania; and Hancock, West
Virginia). The fraction of the total population associated with farms is estimated using
the data presented in Table VII-13. As a result, the fanning population is estimated to
comprise approximately 2.4 percent, 0.7 percent, and 0.5 percent, of the total
populations of Columbiana, Beaver, and Hancock counties, respectively. These values
are estimated based on the average number of individuals per household (as indicated in
Table VII-13), which may underestimate typical fanning households. Thus, to ensure
that the farming population is not underestimated, it is assumed that the farming
population in the vicinity of the WTI facility comprises approximately 2.5 percent of the
total population (the upper end of the values for the local counties). This method may
underestimate the farming population in some subareas (likely those outside the East
Liverpool area, i.e., farther from the facility) and overestimate the farming population in
others (i.e., those near the facility in the more urbanized areas). The remaining 97.5
percent of the population is assumed to be non-farming residents. Furthermore, as
indicated in Chapter VII, 30 percent of the non-farming population are assumed to have
home gardens. Based on these assumptions, the total estimated farming and non-fanning
populations within each subarea is estimated, as shown in Table VIII-19.
Direct and indirect cancer risks are summed for the farming and non-farming
population subgroups, as shown in Table VIII-20. For the residents with home gardens,
risks associated with consumption of homegrown fruits and vegetables (Table VIII-17) are
added to the indirect risks from other pathways and direct risks to develop the total risk
estimates in Table VIII-20. Total average cancer risks for each population subgroup are
multiplied by the corresponding age-distributed census data for each subarea to estimate
the estimated number of additional cancer cases due to facility stack emissions (Table
VIII-21) for each subgroup in each subarea. It should be noted that cancer risks
estimated for children (1 to 6 years old) are applied to the entire age range of children (1
to 12 years) in estimating population risk, with the exception of indirect risks to infants
for which risks from breast milk consumption are applied. In addition, inhalation risks
estimated for children are applied to infants.

-------
Table Vni-21 shows the population risk burden for the farming and non-farming
subgroups for each subarea. The population cancer burden for the WTI study area is
estimated as 3 x 10"3, which implies that over a 70 year lifetime, including 30 years of
WTI operation, 0.003 cancer cases are estimated to occur due to impacts from stack
emissions. As a basis for comparison, statistics from the American Cancer Society (1993)
indicate that the incidence of cancer from all sources is approximately 33 percent. Given
the total population of approximately 54,000 individuals in the study area, this
"background" cancer risk without operation of the WTI facility corresponds to
approximately 18,000 cancer cases over a lifetime.
E. Estimation of Risks Due to Fugitive Emissions
As discussed hi Volume III, several sources of fugitive organic vapor emissions
associated with waste handling, processing, and storage prior to combustion, are
identified at the WTI facility, including:
1) Carbon adsorption bed (CAB) system, which controls emissions from tanks
hi the organic waste tank farm building and from the container processing
area;
2) Seals, valves, and flanges associated with tanks in the organic waste tank
farm building;
3) Waste water holding tank;
4) On-site truck wash station; and
5) Ash handling.
Exposure to emissions from these source may occur to individuals living, working,
or attending school in the vicinity of the WTI facility. Given the nature of the fugitive
vapor releases and the extent of atmospheric dispersion predicted, only risks through
inhalation are quantified for organic vapor emissions from sources 1 through 4. For
fugitive ash emissions (source 5), direct and indirect exposure pathways are evaluated.
Risks associated with these exposure are estimated for three potential exposure
populations: adult residents, child residents, and school-age children.
Exposures are estimated in four quadrants (north, south, east, and west of the
facility) that extend to a distance of 2,000 feet from the facility stack and include
residential and commercial areas of East Liverpool and the East Elementary School to the
north of the facility. For the fugitive organic vapor emissions sources (1 through 4
above), inhalation cancer risks and HQ values are estimated for the 11 surrogate organic
compounds identified hi Chapter IV. For the fugitive ash source (source 5), direct and
External Review Draft
Volume V VIII-20 Do Not Cite or Quote
-------
indirect cancer risks and HQ values are estimated for the metals identified in the ash in
Chapter IV. The following sections summarize the estimated risks for these sources.
1. Estimated Risks Due to Fugitive Organic Vapor Emissions
Inhalation cancer risks and noncancer HQs are estimated within each of the
four quadrants shown in Figure VII-4 for 11 surrogate organic chemicals that were
selected for evaluation in Chapter IV. Total cancer risks and hazard indices for the
four sources of fugitive emissions identified at the facility combined are presented
in Table VIII-22, based on average vapor concentrations. As indicated in Table
VIII-22, lifetime cancer risks due to average exposure to fugitive emissions from
the WTI facility (all four sources of identified fugitive organic vapor emissions
sources combined) are below 5 x 10"6 for children (1 to 6 years old) and school-age
children (7 to 12 years old) and below 1 x 10"6 for adults. Total noncancer hazard
indices are estimated to be significantly below 1, with a maximum estimated
hazard index of 7 x 10~2 for children (1 to 6 years old) who spend most of their
time in the areas east and west of the facility.
In addition to average risks associated with fugitive releases from the WTI
facility, excess cancer risks and noncancer HQs are estimated at the point of off-
site maximum concentration for each of the four fugitive emissions sources. Total
cancer risks and hazard indices for the 11 surrogate chemicals combined are
presented hi Table VIII-23. Cancer risks and HI values for individual substances
are presented in Appendix V-20. It should be noted that the location of
maximum concentration for all sources except the elevated CAB source are on-site,
thus the maximum off-site concentrations at receptors located along the fenceline
are used in the analysis. Since residences near the site are generally between 1,000
and 1,500 feet from the fenceline, the estimation of long-term inhalation risks at
the location of maximum concentration (i.e., based on exposure for 24 hours/day,
350 days/yr, and up to 9 years) is unrealistic and represents worst-case exposure.
Nonetheless, cancer risks for the four organic vapor fugitive emissions sources
identified at the WTI facility are below 1 x 10"5 at the respective locations of
maximum concentration. The noncancer hazard indices for each of the four
fugitive organic vapor sources are below 1.0, indicating that adverse noncancer
health effects due to inhalation exposure are unlikely to result from activities at the
WTI facility.

2. Risks Due to Fugitive Ash Emissions
Fugitive ash emissions from the loading of trucks is expected to occur as
part of routine operations at the WTI facility. Average inhalation cancer risks and
noncancer HQs are estimated within each of the four quadrants shown in Figure
VII-4, for metals and cyanide that have been detected in samples of ash from the
ESP at the facility. In addition, because deposition of fugitive ash emissions may
occur in the vicinity of the WTI facility, cancer risks and noncancer HQ values are
estimated for several indirect pathways, including ingestion of and dermal contact
with soil, and consumption of homegrown vegetables. Indirect risks and HQ
values are estimated for adult and child residents and school children who may be
exposed by these pathways.
Total inhalation cancer risks and hazard indices, based on average airborne
concentrations of ash off-site, are presented in Table VIII-24. Cancer risks and
HQ values for individual substances are presented hi Appendix V-20. As indicated
hi Table VIII-24, lifetime cancer risks due to average inhalation exposure to
fugitive ash emissions from the WTI facility are below 5 x 10'8 for children (1 to 6
years old) and less than 3 x 10~8 for school-age children (7 to 12 years old). For
adults, the estimated average cancer risks do not exceed 2 x 10"8. The highest
cancer risks are predicted for the area west of the site. Noncancer HI values are
estimated to be significantly below 1.0 hi all quadrants; the highest average HI
value of 7 x 10"* is estimated for the area west of the facility for children (1 to 6
years old).
In addition to average risks, cancer risks and noncancer HQs are estimated
at the point of maximum off-site concentration of fugitive ash. Total inhalation
cancer risks and hazard indices are presented hi Table VIII-24. It should be noted
that the location of maximum concentration is on-site, thus the maximum off-site
concentration at a receptor located along the fenceline is used hi the analysis.
Since residences near the site are generally between 1,000 and 1,500 feet from the
fenceline, the estimation of long-term inhalation risks at this location of maximum
concentration (i.e., based on exposure for 24 hours/day, 350 days/yr) is unrealistic
and represents worst-case exposure. Nonetheless, cancer risks are below 1 x 10"6 at
the locations of maximum concentration. The noncancer hazard indices for each
of the population subgroups are significantly below 1.0 (do not exceed 2 x 10"2),
indicating that adverse noncancer health effects due to inhalation exposure to
fugitive ash emissions are unlikely to result from activities at the WTI facility.
Area average cancer risks and HI values for the indirect exposure pathways
are summarized in Table VIII-25. Cancer risks and HQ values for individual

-------
substances are presented in Appendix V-20. Estimated cancer risks and HI values
for the indirect exposure pathways are significantly less than cancer risks and HI
values estimated for the inhalation pathway. For adult residents, lifetime cancer
risks due to average indirect exposure to fugitive ash emissions from the WTI
facility are below
8 x 10~12. For children (1 to 6 years old) and school-age children (7 to 12 years
old), lifetime cancer risks for indirect exposure to metals in fugitive ash emissions .
are not expected to exceed 4 x 10"11 and 1 x 10"11, respectively. The highest cancer
risks are estimated for the areas east and west of the site for all subgroups.
Noncancer HI values are estimated to be significantly below 1.0 in all quadrants;
the highest average HI value estimated, 5 x 10"6, is predicted for the eastern and
western quadrants for children (1 to 6 years old).
Cancer risks and HI values for the indirect pathways of exposure are also
estimated for the location of maximum concentration, as shown in Table VIII-25.
Cancer risks are below 2 x 10~10 at the location of maximum concentration for all
subgroups. The noncancer hazard indices for each of the population subgroups
are significantly below 1.0 (do not exceed 3 x 10"5), indicating that adverse
noncancer health effects due to indirect exposure to fugitive ash emissions are
unlikely to result from activities at the WTI facility.
F. Uncertainties
As emphasized in the recent U.S. EPA exposure assessment guidelines (U.S. EPA
1992b), identification and quantification of uncertainties and variability is an important
element of the risk characterization. Various sources of uncertainty have been identified
in each of the preceding chapters, and an overall assessment of uncertainty in the HHRA
is conducted in Chapter IX. The following sections discuss uncertainties associated with
the risk characterization process and the risk estimates.
1. Uncertainties Associated with the Risk Characterization Process
Uncertainties associated with the methodology used to characterize risks are
based on a number of assumptions used in the risk characterization process. The
key assumptions, the basis for each, and the estimated effects (including magnitude
and direction of effect) on risks are summarized hi Table VIII-26. For many of
these methodological assumptions, potential effects on the overall results of the
HHRA are judged to be minor. The primary exception is the estimation of
impacts at the point of maximum concentration within each subarea, which
assumes that an individual (resident, subsistence farmer, etc.) will be located at this
External Review Draft
Volume V VHI-23 Do Not Cite or Quote
-------
point continuously for the entire exposure duration. However, this assumption is
necessary to provide an indication of the range of potential risks within a subarea.
As noted in section A of this chapter, there is some uncertainty associated
with additive risks (i.e., summing cancer risk estimates and hazard quotients across
chemicals and exposure pathways). The HI approach for the noncarcinogenic
effects of chemicals assumes that multiple sub-threshold exposure could result in
an adverse effect and that a reasonable criterion for evaluating the potential for
adverse effects is the sum of the hazard quotients for individual chemicals. This
methodology, however, is most appropriately applied to substances that induce
the same effect on the same organ. Therefore, to the extent that toxic effects of
the chemicals in the stack emissions are not additive, the HI approach is likely to
result in an overestimate of potential risk.
Cancer risks for multiple chemical exposures are assumed to be additive. As
noted by U.S. EPA (1989b), there are several limitations to this assumption of
additivity. One of these limitations arises from the fact that risks are based on unit
cancer risks that are derived as upper 95th percentiles of the probability
distributions of cancer potency. Because upper 95th percentiles of probability
distributions are not strictly additive, the total cancer risk estimate can become
artificially more conservative as risks from a number of carcinogens are added.
Secondly, the approach routinely applied in cancer risk assessment treats all
carcinogens equally, regardless of the weight-of-evidence class to which a
carcinogen is assigned. Each class is given equal weight; known carcinogens (class
A) are considered equal to probable and possible carcinogens (classes B and C) in
the summation of risks.
Finally, the mechanism of toxicity of any two chemicals may not be the
same and, in fact, might not be independent. Cumulative risk estimates assume
similar mechanisms of action and that mixtures of chemicals do not act
antagonistically or synergistically. The combined risk of antagonistic chemicals is
expected to be less that the sum of the individual risks; whereas, the total risk
from synergistic chemicals could be greater than the sum of the individual risks.
Data and methods to quantitatively assess these types of interactions, however, are
not readily available.
2. Uncertainties Associated with the Risk Estimates
As noted above, Chapter IX presents a quantitative analysis of the
uncertainties involved in each step of the process of estimating indirect risks of two
substances—2,3,4,7,8-PeCDF and arsenic—for a subsistence farmer in subarea El
External Review Draft
Volume V Vin-24 D° Not Cite or Quote
-------
(the subarea of greatest impact). This analysis is intended to evaluate the sources
( of uncertainty affecting the indirect risk estimates. Although subsistence farmers
may not comprise a significant fraction of the population, the conclusions drawn
from the analysis concerning sources of uncertainty likely apply to risk estimates
for other subgroups as well.
3. Uncertainty Associated with the Uncharacterized Emissions
A source of uncertainty in estimating risk not specifically addressed in
Chapter IX is the uncertainty associated with uncharacterized emissions.
Although significant measurements have been obtained to characterize emissions
from the facility, it is known that the characterized fraction of the organic
emissions from the incinerator stack accounts for approximately 40 percent of the
total organic emissions (as discussed in Chapter V of Volume IE). The emission
rates of the constituents within the characterized fraction are likely to be relatively
accurate; however, the compounds emitted in the uncharacterized fraction are
unknown. To provide an indication of the potential effects on total estimated
risks, it is possible for the purpose of illustration to prorate the average cancer risks
to the subsistence farmer hi subarea El associated with the non-dioxin organic
^ compounds by a factor of 2.5 to account for the uncharacterized fraction. The
V ^ inherent assumption hi the prorating process is that the cancer potency of the
uncharacterized fraction is equal to the cancer potency of the characterized
fraction. Total indirect cancer risks to the subsistence fanner hi subarea El are
estimated to be 1.3xlO~6 in this assessment (as discussed earlier), with non-dioxin
organic compounds accounting for approximately 24 percent of the risks. When
the prorating factor of 2.5 is applied to the risks from organic compounds, the
average cancer risks to a subsistence farmer in subarea El become 1.8 x 10"6.
Organic compounds would account for 44 percent of these risks, and there would
be a 36 percent increase in total risk.
G. Comparison of Incremental Dioxin and Furan Exposure to Expected
Background Exposure
As mentioned hi Chapter III, the lack of RfD and RfC toxicity values for
the dioxin-like compounds means that potential adverse noncancer effects from
exposure to dioxins and furans cannot be directly quantified. Therefore,
noncancer HQ values cannot be calculated for the potential risk from exposure to
dioxins and furans. As an alternative, it is useful to compare the estimated
/ incremental exposures to the predicted or expected background exposure levels.
External Review Draft
Volume V Vffl-25 Do Not Cite or Quote
-------
This will serve as an indicator of the potential impact on human health by
showing the additional contribution of the incremental exposure from incinerator
emissions to the overall body burden of dioxin-like compounds from background
exposures.
To make the comparison, it is necessary to calculate the toxic equivalent
(TEQ) dose for the estimated exposure to the dioxin-like compounds. This
calculation-is performed using the LADD data for the adult subsistence farmer in
Subarea El (Table VII-18). For each toxic dioxin and furan congener, the
combined exposures from soil, water, and food are multiplied by the
corresponding TEF value (Table in-2) to obtain a TEQ dose for each congener.
The TEQ doses for each congener are summed to yield a total TEQ dose for the
dioxin and furan congeners. The TEQ dose calculated in this manner is found to
be 7 x 1CT12 mg TEQ/kg-day.
The U.S. EPA discusses estimates of background exposure to dioxins and
furans in its "Draft Dioxin Reassessment" (U.S. EPA 1994b). The range of
background exposures to the U.S. adult population has been estimated as 1 x 10'9
to 3 x 10'9 mg TEQ/kg-day. This includes the predicted background exposure
from multiple sources including the food chain pathway, the inhalation pathway,
and soil ingestion.
Therefore, the LADD of 7 x 10'12 mg TEQ/kg-day for a subsistence farmer
living in the subarea of greatest impact is predicted to be less than 1 percent of the
average daily background dose expected for the U.S. adult population.
Consequently, the probability is low that the incremental exposure due to
emissions from WTI would result in a significantly increased body burden of
dioxin-like compounds for the majority of the population hi the vicinity of the
incinerator.

a - USEPA 1994d.
b - OEPA 1993.
c - This assessment.
d - Although residences in this area may have lead associated with the paint, this source of lead is not considered. However,
because lead emissions from the stack has no affect on the distribution of blood lead levels in local children, as discussed
in the text, this assumption does not affect the results of this assessment.

PAHs in fish are not evaluated because of extensive
metabolism
Noncancer health effects due to infant ingestion of
breast milk are not considered
In estimating subarea populations, even distribution of

Population risks are reasonable because the populations
and sub-groups have been adequately quantitated (e.g.,
the farming population comprises 2.5% of the total
population)
In estimating population risks, the estimated cancer risk
for children from ages 1 to 6 is applied to children
from ages 1 to 12
Basis
EPA (1989) guidance assuming no synergistic or

IX. UNCERTAINTY ANALYSIS
A. Introduction
As noted in the preceding chapters, there are various sources of uncertainty and
variability throughout the risk assessment process. These are inherent in risk assessments of
this nature and are not unique to this assessment. Uncertainty represents incomplete
knowledge about certain parameters, and the values of the parameters generally depend upon
model predictions or limited data. Variability, on the other hand, represents heterogeneity
and inherent differences within a population, across geographic regions, and throughout a
given time period. While the level of uncertainty often can be reduced with a more complete
knowledge base, the level of variability cannot.
The level of uncertainty present in the various phases of the risk assessment, and the
manner by which the uncertainty can be addressed, was discussed extensively by the Peer
Review Panel, who generally agreed that a comprehensive approach was needed to quantify
the degree of uncertainty and its impact on the final risk estimates. This chapter discusses
types and sources of uncertainty, as they apply to the risk assessment process in general and
the WTI incinerator in particular, and outlines and presents the results of a tiered approach to
uncertainty analysis for the risk assessment.
1. Types and Sources of Uncertainty and Variability
As part of the risk assessment process, risks associated with emissions from the WTI
incinerator are estimated as a function (f) of a number of input variables
(x,, • • •, Xt), as follows:
y =/(*,, *,, • • • ,xk, /) (K-1)
where y represents the output variable (i.e., risk estimate). The input parameters include
the waste composition and feed rate into the incinerator, chemical-specific emissions
from the incinerator stack, meteorological and geological conditions, exposure
parameters, and lexicological data. Because some of these input parameters vary with
time, the risk estimate y will also be a function of time, t. In the context of risk
assessment, uncertainty analysis involves the determination of the variation or
imprecision in the final risk estimate that results from the collective variation in the input
parameters (McKone and Bogen 1991).

Generally, several categories of uncertainty can be identified in the risk assessment
process—measurement uncertainty, model uncertainty, and data gaps. Measurement
uncertainty results from inherent errors that accompany most analytic measurements,
such as random sampling errors or systematic biases (nonrandom errors). Examples of
parameters subject to measurement uncertainty include chemical-specific parameters such
as Henry's constant, stack concentrations, and diffusion coefficients.
Model uncertainty arises as a result of gaps in scientific knowledge or simplifying
assumptions used in models to predict chemical and physical process behavior. For
example, the uncertainties associated with modeling the dispersion and deposition of
chemical constituents must be included in the uncertainty analysis.
Throughout the HHRA, an effort is made to use chemical- and site-specific data
wherever possible. However, when these data are incomplete or not available, default
assumptions or generic/surrogate data are used to compensate for these data gaps. This
introduces additional uncertainty into the risk assessment. For example, site-specific
data arc used for crop yields and meteorological conditions, but nationwide data are used
to estimate food intake rates. The range of values for certain chemical and physical
properties of 2,3,4,7,8-PeCDF, such as the vapor/particle partitioning factor, is
estimated from measured values for other PeCDF congeners or other dioxin and furan
congeners.
In addition to these categories of uncertainty, another issue that must be addressed is
variability—across space, in time, and among individuals. Variability occurs when a
quantity that could be described as a single value consists in reality of a distribution of
values depending on time, location, or other factors (Hoffman and Hammonds 1994;
Finkel 1990). For this risk assessment, variability is encountered when describing
emission rates and composition, exposure populations and scenarios, and human
susceptibility to adverse health effects, among other processes. Examples of parameters
that have variable quantities include body weight and food intake rates.
2. Uncertainty and the Risk Assessment Process
The need to address uncertainty in risk assessment is discussed in the 1983 National
Research Council (NRC) report Risk Assessment in the Federal Government (NRC
1983), which states that:
"The dominant analytic difficulty [in decision-making based on risk
assessments] is pervasive uncertainty....there is often great uncertainty in
estimates of the types, probability, and magnitude of health effects
associated with a chemical agent, of the economic effects of a proposed
External Review Draft
Volume V IX-2 Do Not Cite or Quote
-------
regulatory action, and of the extent of current and possible future human
exposures."
Expanding on this general statement, NRC (1994) identifies generic sources of
uncertainty and uncertainty-related issues to be addressed at each step of the risk
assessment process:
• Hazard Identification: What do we know about the capacity of an
environmental agent for causing cancer or other adverse effects in laboratory
animals and in humans?
*• the nature, reliability, and consistency of the particular studies in humans
and in laboratory animals;
»• the available information on the mechanistic basis for activity; and
»• experimental animal responses and their relevance to human outcomes.
• Dose-Response Assessment: What do we know about the biological
mechanisms and dose-response relationships underlying any effects observed in
the laboratory or epidemiology studies providing data for the assessment?
» the relationship between extrapolation models selected and available
information on biological mechanisms;
* the basis for selecting interspecies dose scaling factors to account for
scaling dose from experimental animals to humans; and
* correspondence between the expected route(s) of exposure and the exposure
route(s) utilized in the hazard studies, as well as the interrelationships of
potential effects from different exposure routes.
• Exposure Assessment: What do we know about the paths, patterns, and
magnitudes of human exposure and number of persons likely to be exposed?
>• the basis for the values and input parameters used in each exposure
scenario;
External Review Draft
Volume V IX-3 Do Not Cite or Quote
-------
»• the major factor(s) thought to account for the greatest uncertainty in the
exposure estimate, due to either sensitivity or lack of data; and
» the link of the exposure information to the risk descriptors (e.g., highly
exposed or highly susceptible groups or individuals).
• Risk Characterization: What are the strengths and limitations of the assessment?
»• descriptive information summarizing the assumptions and uncertainties that
are associated with the numerical estimates of risk; and
> consideration of alternative approaches involves examining selected
plausible options for addressing a given uncertainty.
In order to determine how these general types and sources of uncertainty apply
specifically to the HHRA, the processes of chemical transport from the incinerator to
human receptors must be evaluated in greater detail. Each process step is accompanied
by a body of data and specifically developed models. These processes and potential
sources of uncertainty include the following:
• Source Emissions—Data from trial bums, quarterly performance tests, and
predicted waste feed information are used as the primary basis for estimating the
source emissions. Because these data may not necessarily represent long-term
emissions from the WT1 incinerator, and are subject to fluctuations in feed
composition and quantities and incinerator operation, the emission rate and stack
gas composition can be uncertain and variable.
• Atmospheric Dispersion and Deposition—Once substances have been emitted to
the atmosphere, their transport and dispersion to receptor sites will be dictated
by meteorological conditions, physical and chemical processes, and land use and
geological conditions. Since many of the heavy metals of concern are particle-
bound, their wet and dry deposition rates will depend on the size distribution of
the emitted paniculate matter. The degree of uncertainty introduced into the
risk assessment will depend on the accuracy of dispersion models and the
quality of the input data (e.g., wind speed and direction, vapor/particle partition
factor) used.

-------
• Intermedia Transfer—Additional models are necessary to determine the fate of
atmospheric materials that deposit to the ground surface—including direct
deposition to crop plants and deposition to surface soils and waters, with
subsequent transport in environmental media and incorporation in the food
chain. These models rely upon numerous site- and chemical-specific
parameters, including site-specific parameters such as crop yields and soil
properties, and chemical-specific parameters such as soil/water distribution
coefficients and soil degradation rates. The uncertainty resulting from the use
of these models depends on the quality of the data used for these parameters.
• Human Exposure Patterns—Numerous assumptions are required to estimate
direct exposure via inhalation of ambient air, and indirect exposures through
food and drinking water intake. There is uncertainty and variability associated
with individual behavior patterns and the exposure factors used in the
assessment. While some nationwide surveys are available to characterize the
general variability in human behavior patterns, uncertainty is introduced when
applying these data to a certain subpopulation of interest.
• Dose-Response Relationships—In most cases, toxicity factors for assessing
human health risk must be derived from laboratory animal studies. Even when
data on actual human responses to chemical exposures are available, these data
usually correspond to high dose conditions and must be extrapolated to the
lower doses more typical of routine environmental exposures. The reliance on
toxicity data from animal studies or high dose human exposures introduces
additional uncertainty into the risk assessment.
Each of these major potential sources of uncertainty is considered in developing the
quantitative methodology for uncertainty analysis described in this chapter.
B. A Three-Tiered Approach to Uncertainty Analysis
The uncertainty analysis for the risk assessment consists of three tiers, or levels of
analysis.
• Tier I—Quantification and analysis of input parameter variances
Where possible, input parameters used in the risk assessment are accompanied by
the estimation error or the experimental standard deviation associated with the
External Review Draft
Volume V IX-5 Do Not Cite or Quote
-------
parameters. A summary and justification of the assumptions used for each input
parameter range are included.
• Tier n—Sensitivity analysis
This analysis assesses how model predictions are affected by model reliability and
data precision. The goal of a sensitivity analysis is to rank the input parameters on
the basis of their contribution to variance in the output.
• Tier in—Variance propagation
This final tier involves quantifying how the overall accuracy of risk estimates is
related to the variability and uncertainties associated with the models, inputs, and
exposure scenarios.
Recent examples of applications of this type of approach to uncertainty in risk assessment
include the estimation of human health risks associated with exposure to hexachlorobenzene
and benzo(a)pyrene (BaP) through the consumption of homegrown food (McKone 1994);
exposure to perchloroethylene (PCE) in California ground water (McKone and Bogen 1991);
risks to children playing in soils contaminated with benzene and BaP (Thompson et al. 1992);
and carcinogenic health risks due to the emissions of a coal-fired power plant (Seigneur et al.
1994). A more detailed description of each tier and the associated implications is discussed
below.
1. Tier I—Quantification of Input Parameter Variances
The first tier in the uncertainty analysis quantifies ranges for the input parameters,
reflecting uncertainties and variances in their values. For those parameters that are
experimentally determined, the experimental standard deviation is provided. Other
parameters that are calculated from regression equations are accompanied by the standard
error of the estimator.
Associated with the fate and transport models are a number of partition and
biotransfer factors, some of which may be uncertain by several orders of magnitude.
Input parameters likely to have uncertainty factors greater than a factor of five include
octanol-water partition coefficients (K^), organic-carbon partition coefficients (K^.),
Henry's law constant (H), and steady-state biotransfer factors (Ba). Each of these
parameters is chemical-specific. Available literature is used to determine appropriate
"most likely" values and ranges for these parameters.
The output variables from some models serve as input variables to other models.
For each model used, an estimate is made of the uncertainty associated with that model.

-------
For example, the output variables from atmospheric dispersion models are ambient air
concentrations of the emitted species. These calculated concentrations are used to
determine exposure levels at the receptor site. Therefore, it is necessary to estimate the
level of accuracy of the model in order to quantify the uncertainty of the model outputs.
For example, at this site, the atmospheric dispersion model ISC-COMPDEP simulates
atmospheric dispersion to within a factor of approximately four (Chapter V of Volume
IV). .-
2. Tier H—Sensitivity Analysis
Some parameters have a more significant effect on the estimates of health risks
calculated by the models than others. Therefore, to reduce the computational burden to
a reasonable level, the uncertainty analysis focused on those influential parameters to
which the calculated health risks are most sensitive. These influential parameters are
identified through a sensitivity analysis.
The goal of a sensitivity analysis is to rank the input variables on the basis of their
contribution to variance in the output. Sensitivity analyses can be either global or local.
A global sensitivity analysis quantifies the effects of variation in parameters over their
entire range of values. A local sensitivity analysis is used to examine the effects of
small changes in parameter values at some defined point in the range of outcome values.
The process for identifying the influential parameters involves computing several
dimensionless parameters for each input variable. The first required parameter is the
local sensitivity index (LSIj), which describes the effect on a model output for a small
perturbation hi an input parameter (Seigneur et al. 1994). The advantage of local
sensitivity analysis is the relative ease in application, since the range of parameter values
is not required.
It is important, however, that the model output not only be a sensitive function of an
input variable (i.e., high LSI, values), but also that the input variable has a significant
range of expected values to allow the input variable to influence the model output. For
example, if a model output exhibits strong local sensitivity to a particular input variable
that has a relatively constant and well known value, this input variable will not be a
particularly influential parameter. Thus, to determine the global sensitivity of an input
parameter, another dimensionless parameter that provides a measure of the expected
variation of an input variable over its range of probable values is needed. The
coefficient of variation (CVj) is used for this purpose, and is calculated as follows:
External Review Draft
Volume V IX-7 Do Not Cite or Quote
-------
CVt = ff (DC-2)
where at is the standard deviation of the parameter distribution and Xj is the mean value
of the input parameter Xj.
Given the assumptions of this analysis, the product of the local sensitivity index,
LSIj, and the coefficient of variation, CVj, is directly related to a global sensitivity
index, GSI;, defined as follows:
GSI. = (A;y<)m" (IX-3)
where (AyJ^,, is the maximum range in risk estimates resulting from the maximum
variation in an input parameter, and y is the risk estimate using typical values for all
input parameters. The result is a representative measure of the impact that an individual
parameter may have on the risk model. By computing and comparing values of GSI, for
all of the input parameters, the influential parameters can be identified and ranked in
importance of affecting the risk outcome. This approach to sensitivity analysis is similar
to that applied by U.S. EPA (1994b,c).
For the influential parameters identified, it is also useful to determine the probability
distribution functions (PDFs) for these parameters. The PDF provides a measure of a
parameter's central tendency and allows the estimation of extreme values. Knowledge of
the PDF is also useful for modeling the parameter as a random variable. While
available data may be adequate to determine the shape of the PDF for some parameters,
subjective PDFs might need to be estimated for other parameters based on scientific
judgment (Haimes et al. 1994). For example, measured values for parameters such as
partition coefficients and biotransfer factors generally follow lognormal distribution
functions (McKone 1994). Therefore, for a particular chemical, if only limited data are
available for characterizing distributions for these parameters, a lognormal PDF is
assumed to apply. For other parameters where only minimum, maximum, and most
likely values are known, either triangular or uniform distributions are used (Haimes et
al. 1994; Finley et al. 1994).
3. Tier El— Variance Propagation
After the input parameter variances have been determined (Tier I) and the most
influential parameters and their PDFs identified (Tier n), the final step in the uncertainty
analysis is to evaluate the combined effect of the identified uncertainties on the output

-------
variable (i.e., risk to human health). Risks to human health are estimated using a series
of models, with the output variables from some models serving as input variables to
other models. The process for ascertaining the cumulative effect of input parameter and
individual model uncertainties on the ultimate risk estimates is known as variance
propagation. One of the results of the variance propagation is a probability distribution
for the model output. Once this PDF is estimated, the expected likelihood or
probabilities of the risk predictions are known and confidence levels can be established
for various levels of risk.
A widely used variance propagation method is through Monte Carlo analysis
(Hoffman and Hammonds 1994; Thompson et al. 1992). In a Monte Carlo method, each
of the influential input parameters is represented by a PDF that defines both the range of
values for the parameter and the likelihood that the parameter has a value in any
subinterval of that range. The model is iterated, selecting each member of the input
parameter set by random sampling. Iterations are continued until a variance of the
output can be determined. This variance reflects the combined impact of the variances
in the input parameter set as propagated through the model.
An alternative to the Monte Carlo method is Latin hypercube sampling (LHS),
which is a modified Monte Carlo method. LHS uses stratified random sampling to
ensure an even selection of input parameter values across the range of possible values.
If the output is a monotonic function of the input, LHS has been shown to be more
efficient than an unmodified Monte Carlo method (Iman and Helton 1988). LHS is also
preferable when parameter values in the low- or high-end tails of the PDF are important.
In both Monte Carlo and LHS analyses, sample values for each input parameter
generally are selected independently of the values of other input parameters. However,
some of the input parameters may be correlated. For example, values of body weight
and ingestion rates are not expected to be independent of each other. For pairs of
correlated variables, the random sampling methodology should be modified to preserve
these relationships.
C. Implementation of Tiered Approach to Uncertainty Analysis
As discussed in previous chapters of this report, exposures to a variety of chemicals
released from several on-site sources may occur through numerous direct and indirect
pathways. The application of all three tiers of uncertainty analysis for all chemicals and
every exposure pathway would be an enormous undertaking. Therefore, a more focused
approach is adopted for this risk assessment.
The uncertainty analysis for the HHRA addresses source emissions, atmospheric
dispersion, and exposure assessment components of the risk assessment. The toxicity criteria

(i.e., slope factors and reference doses) are not treated as input variables in the uncertainty
analysis, however, because it is generally not possible to quantify the uncertainty in
developing the criteria. For example, the uncertainty in developing a slope factor for dioxins
and furans from laboratory animal data cannot be reliably estimated. Furthermore, the
uncertainty associated with the slope factor for certain dioxin and furan congeners, such as
2,3,4,7,8-PeCDF, is greater than for congeners that have been studied more extensively,
such as 2,3,7,8-TCDD.
Some of the steps in the uncertainty analysis can be eliminated based on prior knowledge
of the fate, transport, and toxicity of the chemicals. For example, the greatest risk has been
determined to occur through indirect exposure pathways (Chapter Vm). In order for a
chemical to pose a significant threat to human health via indirect exposure pathways, the
chemical must be relatively persistent in environmental media, bioconcentrate in human or
animal tissues, or both. For these reasons, there are a relatively limited number of
chemicals that contribute significantly to the risk posed by indirect exposures. Screening of
chemicals and exposure pathways of greatest concern is performed to focus the application of
the second and third tiers of the uncertainty analysis.
The uncertainty analysis adopted for the HHRA consists of the following elements:
1. Tier I and n analyses are performed for the exposure assessment for the following
specific cases:
• The organic chemical estimated to pose the greatest carcinogenic health risk to
the most highly exposed subgroup via indirect exposure pathways (i.e., indirect
exposure to 2,3,4,7,8-PeCDF by adult subsistence farmers); and
• The metal estimated to pose the greatest carcinogenic health risk to the most
highly exposed subgroup via indirect exposure pathways (i.e, indirect exposure
to arsenic by adult subsistence farmers).
For each of these cases, the uncertainty analysis is performed on the risks at the
location where risk posed by the chemical is greatest. For 2,3,4,7,8-PeCDF, the
route of indirect exposure that poses the greatest risk is associated with vapor-phase
uptake by vegetation. Thus, the uncertainty analysis for this chemical and pathway
focuses on the location where vapor uptake is greatest. For arsenic, the greatest risk
is associated with particulate-phase wet deposition. Thus, the uncertainty analysis
for this chemical and pathway focuses on the location where wet deposition is
greatest. Both of these locations are situated in subarea El.

-------
As discussed in Chapter Vm, none of the chemicals analyzed in this risk
assessment are determined to result in a hazard index (HI) value exceeding 1.0,
indicating a very low potential for noncancer health effects. For this reason, the
quantitative uncertainty analysis addresses carcinogenic risk only.
2. A Tier I analysis is performed for the emissions characterization step and the
atmospheric dispersion model for 2,3,4,7,8-PeCDF and arsenic, so that uncertainties
associated with these separate components are identified. This Tier I analysis
consists of the identification of ranges for these variables and an estimation of the
PDF. These components are also included in the Tier n sensitivity analysis.
3. Steps 1 and 2 above are combined in a Tier HI analysis. This consists of a modified
Monte Carlo (i.e., Latin hypercube sampling) simulation using the estimated
uncertainties and variabilities for the influential parameters identified in the
sensitivity analysis.
Using the approach outlined above, this focused application quantifies the uncertainties for
the chemicals and exposure pathways of greatest concern. This approach is consistent with
EPA's recent risk characterization guidance, which recommends that uncertainty analyses for
risk assessments be focused, rather than including the evaluation and assessment of "every
conceivable exposure scenario for every possible pollutant" (U.S. EPA 1992a, 1995a).
D. Results
1. Estimation of Input Parameter Ranges
Point estimates of risk developed using typical values for each of the input
parameters required by the model equations summarized in Chapter VI and in Appendix
V-7 are presented in Chapter vm. In order to estimate the uncertainty associated with
this risk estimate, ranges of the possible values for the input parameters are determined,
and are summarized in Table IX-1. The rationale for the selection of each of the ranges
are discussed in Appendix V-21. While ranges are defined based on available data or
guidance to the extent possible, scientific judgment is used to estimate conservative
ranges where appropriate data or guidance are unavailable.
2. Sensitivity Analysis
The next step in the uncertainty analysis is to determine which of the input
parameters have the ability and the range in values to influence the model output. To

determine these influential parameters, global sensitivity index (GSI) values are
calculated for each input parameter using equation (IX-3).
The results of the sensitivity analysis are summarized in Table IX-2. The "primary"
influential parameters that are retained for the uncertainty propagation are those with an
absolute GSI greater than 0.25. This corresponds to the parameters for which the range
of possible output values (i.e. , the range of risk estimates) are greater than 25 % of the
average output value (i.e., the typical risk estimate). To determine whether the
"primary" influential parameter retention criterion of GSI>0.25 is sufficient to represent
the total output variability, a group of "secondary" influential parameters is also
selected. This group includes parameters with GSI values between 0.05 and 0.25. A
variance propagation using both the primary and secondary influential parameters will be
compared to the results using only the primary influential parameters.
The influential parameters identified in the sensitivity analysis are summarized
below, in order of decreasing influence:

where OC80il is the fraction of organic carbon in the soil, R is the gas constant, and T is

The uncertainty in these parameters is dependent on the uncertainty in Kw and H, both
of which are identified as primary influential parameters. Thus, while these five

they are evaluated implicitly through the inclusion of K^, and H in Tiers n and m.

Uniform:
p(x) = J_
c-a
where a is the minimum value of x, and c is the maximum value. This distribution
is used primarily for parameters for which a range is known and either no most
likely value is known or the data are evenly distributed across the range.
Because many physical parameters are non-negative and have been found to follow
positively skewed distributions, the lognormal distribution is commonly used to represent
such parameters (McKone 1994; CalEPA 1993; McKone and Bogen 1991; Finkel 1990:
McKone and Ryan 1989). Lognormal distributions are often used when uncertainties are
expressed on a multiplicative order-of-magnitude basis (e.g., factor of 2). This
multiplicative uncertainty factor is related to the geometric standard deviation.
When a likely range of values for a parameter has been specified or estimated, this
range is assumed to represent the upper and lower bounds of a 95 percent confidence
interval. Thus, the possibility of the value of a parameter falling outside the specified
range exists, but is assumed to be unlikely. For all estimated ranges, professional
judgment is used to select a conservative estimate that corresponds to at least a 95
percent confidence interval. Specifying these upper and lower bounds (as opposed to
other upper and lower bounds, such as a 90th percent upper bound and a 10th percent
lower bound confidence level) allows a convenient relationship between these bounds and
the statistical parameters of the distribution. For a lognormal distribution, the geometric
standard deviation relates the geometric mean (GM) with the upper and lower bounds of
a 68 percent confidence interval (x^^ and x^LS) and the upper and lower bounds of a 95
percent confidence interval (X95UB and x^^)1 as follows (Ott 1995):
C1D = "*95t/B = "*68L* _ _ 6U£ (DC-15)
X9SL£
'The upper and lower bounds of a 68 percent confidence interval correspond to the 84
and 16 percentile levels of the cumulative probability distribution, respectively. The upper
and lower bounds of a 95 percent confidence interval correspond to the 97.5 and 2.5
percentile levels of the cumulative probability distribution, respectively.

Similarly, for parameters for which a most likely value and an uncertainty factor are
known (e.g., the air concentration is uncertain by a factor of four), the uncertainty factor
(UF) is assumed to represent the square of the GSD, and the upper bound is estimated to
be the product of the geometric mean and the uncertainty factor:
= (GM)(UF) aX-17)
UF = 95VB =

(IX-18)
In each case, professional judgment is used to ensure this upper bound is a reasonable
approximation of the 95th percent confidence interval upper bound.
Most parameters in this uncertainty analysis are modeled as lognormal distributions;
however, if appropriate data are limited to the point where variances cannot be estimated
accurately, triangular distributions are used (Finley et al. 1994; Haimes et al. 1994).
Use of such a distribution does not mean that the actual distribution is triangular; rather,
it is used as a reasonable way to represent the currently available data (Finley et al.
1994; Haimes et al. 1994).
The primary influential parameters identified in the sensitivity analysis, their most
likely values, and PDFs are summarized below. Estimates of correlation coefficients
between parameters expected to be related are also provided. Except where noted
otherwise, all of the following parameters are modeled as lognormal.
a. Indirect exposure to 2,3,4,7,8-PeCDF:
• Henry's constant (H)
The Henry's Law constant of 6.2xlO'6 atm-m3/mol for 2,3,4,7,8-PeCDF
(U.S. EPA 1994b), which is calculated from the chemical's vapor
pressure/water solubility (VP/WS) ratio (Lyman et al. 1990), is used for the
most likely value of H. Vapor pressures estimated for PeCDF congeners

-------
range from 1.5xlO~9 to 4.3 xlO"9 mm Hg (U.S. EPA 19945), spanning a
factor of about three. Only one value is reported for the water solubility of
PeCDFs; however, values for other dioxin and furan congeners have ranges
spanning about one order of magnitude (U.S. EPA 1994b). Therefore, the
Henry's constant for 2,3,4,7,8-PeCDF is assumed to be accurate over a
factor of approximately 30, which corresponds to a GSD of 2.34.
Assuming this range represents the 95 percent confidence interval of a
lognormal distribution, the geometric mean is estimated from equation
(DC-11) to be 4.4xl(T6 atm-m3/mol, with the 95 percent confidence
interval ranging from 8.0xlO~7 to 2.4xlO~5 atm-m3/mol.
• Octanol/water partition coefficient
The only value of log K^ reported by U.S. EPA (1994b) for 2,3,4,7,8-
PeCDF is 6.92 (Sijm et al. 1989), which corresponds to a value for K^ of
8.3 x 106; this value is used for the most likely value of K^. Values have
been reported for log K,^ for other PeCDF congeners ranging from 6.19 to
6.79 (Sijm et al. 1989). Thus, the range of log K^ values for all PeCDF
congeners ranges over one unit, which corresponds to a range of about an
order of magnitude for K^ values. Because the value of log K^ for
2,3,4,7,8-PeCDF is the upper limit of the range of values for all PeCDF
congeners, the value of K^ for 2,3,4,7,8-PeCDF is conservatively
estimated to range over two orders of magnitude, which corresponds to a
GSD of 3.16. Assuming this range represents the 95 percent confidence
interval of a lognormal distribution, the geometric mean is estimated from
equation (IX-11) to be 4.2 xlO6 (which corresponds to a log K,,,, of 6.6),
ranging from 4.2xl05to4.2xl07 (which corresponds to values of log Kow
ranging from 5.6 to 7.6).
• Dispersion factor
At the point of maximum vapor uptake, the most likely value for the
dispersion factor for 2,3,4,7,8-PeCDF is 0.914 (/zg/m3)/(g/sec). A series of
sensitivity tests of the model predictions to a range of inputs was performed
to assess the response of the model to uncertainties in the model input
parameters (Chapter V of Volume IV). Based on an analysis of these
sensitivity tests and the performance of other similar steady-state Gaussian
models, it is estimated that the uncertainty of the annual average
concentration predictions from ISC-COMPDEP is a factor of 4, which

corresponds to a GSD of 2. Assuming this range represents the 95 percent
confidence interval of a lognonnal distribution, the geometric mean is
estimated from equation (IX-11) to be 0.72 (/ig/m3)/(g/sec), ranging from
0.18 to 2.9 0*g/m3)/(g/sec).
• Emission rate
Based on data collected during the February 1994 trial bum (four test runs)
and the 22 performance test runs conducted between August 1993 and
August 1994, the average emission rate of 2,3,4,7,8-PeCDF is 4.7xlO~10
g/sec, with values ranging from 9.0xlO~u to 1.5xlO~9 g/sec. These data
from the trial burn and performance tests are used to determine a
cumulative probability distribution for the emission rate.
Studies by Zacharewski et al..(1988) and Mason et al. (1987) have
shown selected brominated and brominated-chlorinated dioxins to be
comparable in toxicity to chlorinated dioxins in certain short-term toxicity
assays. Because EPA-approved methods for analyzing brominated and
brominated-chlorinated dioxins and furans are not available, the presence of
brominated compounds in the stack emissions was not determined.
f However, since brominated aromatics are not as widely used as chlorinated
""-^ aromatics, only a small fraction of the total halogenated dioxins and furans
that form during hazardous waste incineration are expected to be
brominated. Based on an initial examination of the waste profiles for the
first nine months of operation, the amount of bromine in the waste stream is
less than one-twentieth of the amount of chlorine. In order to account for
the potential impact of the brominated compounds, the dioxin and furan
emissions are prorated by an uncertainty factor in this uncertainty analysis.
The 2,3,4,7,8-PeCDF emission rate is multiplied by this uncertainty factor,
which is defined to have a minimum value of 1.0, a most likely value of
1.05 (i.e., a one-twentieth increase), and a maximum value of 1.5. The
maximum value for the uncertainty factor of 1.5 reflects professional
judgment that brominated aromatics will not likely exceed one third of the
chlorinated aromatics in waste feeds. Because of the lack of available data
for this parameter, a triangular distribution is assumed (Finley et al. 1994).

estimated to be 0.61 for 2,3,4,7,8-PeCDF . Because extremely limited
2,3,4,7,8-PeCDF-specific data are available for this parameter, a triangular
distribution is assumed (Finley et al. 1994). For the maximum and
minimum values, the range of 15 measurements from six studies of <£ for
PeCDF congeners, 0.0 to 0.71, is used (U.S. EPA 1994b,c).
Bioconcentration factors (BCD
McLachlan et al. (1990) reported the only measured value of BCF for
2,3,4,7,8-PeCDF, 3.1, which is used for the most likely value. Values are
reported for other dioxin-like compounds in beef and milk fat ranging from
0.05 to 5.7 (U.S. EPA 1994b; McLachlan et al. 1990; Fries and
Paustenbach 1990; Jensen and Hummel 1982; Jensen et al. 1981; Arstilla et
al. 1981; Parker et al. 1980; Firestone et al. 1979), with lower chlorinated
congeners generally having higher values of BCF than higher chlorinated
congeners. Taking this association of decreasing bioconcentration ratios
with increasing chlorination into consideration, the range of BCF values
reported for tetra-, penta-, and hexa-chlorinated dioxins and furans, from
0.73 to 5.7, is selected to represent the estimated uncertainty in the BCF
value for 2,3,4,7,8-PeCDF in the fat content of beef, milk, pork, chicken,
and eggs. Because extremely limited 2,3,4,7,8-PeCDF-specific data are
available for this parameter, a triangular distribution is assumed (Finley et
al. 1994).
Beef intake rate
The site-specific most likely value for IR^ is 81 g/day. This value and the
cumulative distribution function were extrapolated from a 1987-88 USDA
national food consumption survey (USDA 1993, 1982), as summarized in
Chapter VI. Based on this survey, the upper and lower bounds of the 95
percent confidence interval for beef intake rates are 321 and 14 g/day,
respectively. The ingestion rate of beef is expected to be related to body
weight. To account for this relationship, a correlation coefficient between
and BW of 0.9 is assumed.
• Fraction of milk that is fat
The most likely value for the fat content of milk is assumed to be 0.02
(U.S. EPA 1994b). According to data reported by Pennington (1989), the
value of fat,^ ranges from 0.002 (skim milk) to 0.037 (whole milk).

Because the data are fairly evenly distributed across this range, a uniform
distribution is assumed to apply for this parameter.
Body weight (BW)
Data and cumulative probability distributions for adult (ages 18 to 75) body
weights were collected during the second National Health and Nutrition
Examination Survey (NHANES n), conducted between 1976 and 1980.
Over 20,000 individuals in the United States ranging in age from 6 months
to 74 years participated in this survey. Based on this survey, the 5th and
95th percentile body weights are 52 and 97 kg, respectively. The
cumuktive PDF from this survey (AfflC 1994, U.S. EPA 1990b) is used in
this uncertainty analysis.
Fraction of beef that is fat
According to data reported by Pennington (1989), the average fat content of
beef (including brisket, chuck, flank, ground, ribs, round, shank, short
loin, and wedge-bone sirloin) is 0.23, ranging from 0.12 to 0.35. Because
the data are fairly evenly distributed across this range, a uniform
distribution is assumed to apply for this parameter.
• Milk intake rate
The site-specific most likely value for n^ is 184 g/day. This value and
the cumulative distribution function were extrapolated from a 1987-88
USDA national food consumption survey (USD A 1993, 1982), as
summarized in Chapter VI. Based on this survey, the upper and lower
bounds of the 95 percent confidence interval for milk intake rates are 918
and 10 g/day, respectively. The ingestion rate of milk is expected to be
related to body weight. To account for this relationship, a correlation
coefficient between IR^ and BW of 0.9 is assumed.
• Diet of beef cattle (DFforage, DF^, DF.^, DF.J
For beef cattle, reported soil ingestion rates range from 1 to 18% of dry
matter intake, which is 1 to 15 % of total intake, with a typical value of 3 %
(U.S. EPA 1990a, Thorton and Abrams 1983). Therefore, forage, grain,
and silage comprise the remaining portion of the diet. Typical total intake
for beef cattle reportedly consists of 72% forage, 4% grain, and 21 % silage
(U.S. EPA 1990a, Ensminger 1976).
External Review Draft
Volume V IX-21 Do Not Cite or Quote
-------
Generally, soil ingestion is inversely related to the availability of forage
(Fries and Paustenbach 1990). The higher soil ingestion rates likely occur
under poor pasture conditions with sparse vegetation, whereas periods of
lush plant growth are associated with low soil intake. Because beef cattle
often subsist on diets that are largely forage (Fries and Paustenbach 1990),
the upper limit of the forage diet fraction is assumed to be 99 % , with a soil
diet fraction of 1 % , in which case the lower limits of the silage and grain
diet fractions would both be 0% . Under poor pasture conditions or for
various dietary considerations, the lower limit of the forage diet fraction is
estimated based on professional judgment to be one third (33 %),
approximately a factor of two lower than the typical value of 72%, with the
soil ingestion increasing to its maximum value of 15 % , and the balance of
the diet comprised of an increase from the most likely value in either the
silage or grain fractions (i.e., either 4% grain and 48% silage or 31 % grain
and 21 % silage). The higher silage diet fraction corresponds to periods of
short growing seasons and low rainfall; the higher grain diet fraction
corresponds to periods of beef cattle fattening (Fries and Paustenbach 1990,
NRC 1984).
In summary, for beef cattle, the diet fractions are assumed to range
from 33 to 99% forage, 1 to 15% soil, 0 to 31 % grain, and 0 to 48%
silage. Because of the limited data availability, triangular distributions are
assumed for the forage, grain, and soil diet fractions; the silage fraction is
defined by a mass balance with the other three diet components. To
account for the inverse relationship between soil and forage intake, a
correlation coefficient of —0.9 between DFforage and DF,oil is assumed.
• Diet of dairy cattle (DFforase, DF^, DF>illlge,
Dairy cattle generally do not graze to the extent that beef cattle do, partly
because high-producing cows are unable to meet their energy requirements
when pasture is their main food source (Bath et al. 1985). Therefore, a
99% upper bound forage diet fraction for dairy cattle is not likely. Typical
total intake for dairy cattle reportedly consists of 64% forage, 15% grain,
and 19% silage, with the remaining 2% intake being soil (U.S. EPA
1990a).
Reported soil ingestion rates range from 1 to 7% of total intake, with a
typical value of 1 % for lactating dairy cows and 4% for nonlactating cattle
(U.S. EPA. 1990a, Fries et al. 1982a). Because of the low cost of pasture

-------
grass and the high nutritive value of grain, it is unlikely that the diets of
dairy cattle are completely devoid of either roughage or grain (Bath et al.
1985, NRC 1978). Therefore, based on professional judgment, the lower
limits of the forage and grain diet fractions are estimated to be 30% and
7%, respectively, approximately a factor of two lower than the typical
values. For nutritional reasons, grain does not generally exceed 50% of the
total diet (Stallings 1995). The maximum forage diet fraction is estimated
to be 92 % by assuming all other diet components are at their minimum
values. The maximum silage diet fraction is estimated to be 56% by
assuming forage and grain are at their minimum values and soil is at its
maximum value (assuming soil and forage ingestion are inversely related).
In summary, for dairy cattle, the diet fractions are assumed to range
from 30 to 92% forage, 1 to 7% soil, 7 to 50% grain, and 0 to 56% silage.
Because of the limited data availability, triangular distributions are assumed
for the forage, grain, and soil diet fractions; the silage fraction is defined
by a mass balance with the other three diet components. To account for the
inverse relationship between soil and forage intake, a correlation coefficient
of -0.9 between DFforage and DF,^ is assumed.

For arsenic, Baes et al. (1984) report the most likely values of the plant/soil
bioconcentration factors for nonvegetative/reproductive portions of food
crops and feed plants to be 0.006. Available plant and product elemental
concentration data for arsenic (Baes et al. 1984, Shacklette et al. 1978,
Vinogradov 1959) show values of Br ranging from approximately 0.002 to
0.78. Assuming this range the 95 percent confidence interval of a
lognormal distribution, the GSD is estimated from equation (IX- 16) to be
4.44, and the geometric mean is estimated from equation (IX-11) to be
0.002.
• Beef biotransfer factor
Baes et al. (1984) and Ng (1982) provided the only available estimates of
the ingestion-to-beef biotransfer factor for arsenic of 0.002 day/kg, which is
used for the most likely value for Ba^f. The GSD of the arsenic
biotransfer factors was not reported, however, GSDs for other elements

-------
range from 1.3 to 3.8. Therefore, the GSD of Ba^f for arsenic is
conservatively estimated to be 3.8, which corresponds to a geometric mean
of 8.2xlO~4 and values for Ba^ ranging from 5.7xlO~5 to 0.012.
• Wet deposition factor
At the point of maximum wet deposition, the most likely value of the
maximum wet deposition factor is 0.22 (g/m2-yr)/(g/sec) (Chapter H of
Volume IV). The actual peak values could range to as low as one tenth this
value, or 0.022 (g/m2-yr)/(g/sec). For reasons discussed in Chapter IV of
Volume IV, the wet deposition algorithm is likely to overestimate near-field
wet removal rates and, therefore, wet deposition fluxes. This is due to the
use of scavenging coefficients that implicitly include the effects of both
below-cloud and in-cloud scavenging, whereas, near the stack, only below-
cloud scavenging occurs under most conditions. To estimate an upper limit
for this maximum wet deposition factor, the uncertainty in the ISC-
COMPDEP model (factor of four) is used, which corresponds to an upper
limit of 0.884 (g/m2-yr)/(g/sec). However, this is considered very
conservative because the wet deposition algorithm is likely to have a bias
toward overprediction of wet deposition fluxes in the near field, where the
peak deposition is predicted to occur. Because no information is available
regarding of the probability distribution of this parameter, a triangular
distribution is assumed (Finley et al. 1994).
• Soil/water distribution factor (KdJ
The most likely value for Kd8 for arsenic is 200 L/kg (Baes et al. 1984).
This value of Kds is estimated by Baes et al. (1984) to be uncertain over
three orders of magnitude, which corresponds to a GSD of 5.62. Assuming
this range represents the 95 percent confidence interval of a lognormal
distribution, the geometric mean is estimated from equation (Dt-11) to be
45 L/kg, ranging from 1.4 to 1,400 L/kg.
• Emission rate
The most likely value for the emission rate of arsenic is 3.7xlO~5 g/sec
(Chapter ffl of Volume HI). Observed variations in the system removal
efficiencies (SRE) for arsenic were low, therefore the variation in the
emission rate of arsenic will be primarily due to variability in the waste
feed composition. As discussed in Appendix ffl-1, the waste feed

-------
composition could vary by as much as an order of magnitude for metals.
Therefore, the arsenic emission rate is assumed to vary over an order of
magnitude, which corresponds to a GSD of 1.78. Assuming this range
represents the 95 percent confidence interval of a lognormal distribution,
the geometric mean is estimated from equation (TX-11) to be 2.7xlO~5
g/sec, ranging from 8.4xlO~6 to 8.4xlO~5 g/sec.
Beef intake rate
The same probability distribution for beef ingestion rates used for the
2,3,4,7,8-PeCDF uncertainty analysis is used.
• Pork biotransfer factor
Belcher and Travis (1989) provided the only available estimate of the
ingestion-to-pork biotransfer factor for arsenic of 0.0037 day/kg, which is
used for the most likely value for Ba^. Because the GSD of the arsenic
biotransfer factors was not reported, the value of 3.8 used for the GSD of
Ba^f for arsenic is assumed, which corresponds to a geometric mean of
0.0015 and values for Ba^ ranging from 1.1 xlO"4 to 0.022. Lognormal
distributions have been used to represent biotransfer factors by CalEPA
(1993), McKone and Ryan (1989), and Ng (1982).
• Environmental half life on plant surfaces (t]/2)
The most likely value for t,/2 is assumed to be 14 days (U.S. EPA 1994b,c),
which is the value used by the U.S. Nuclear Regulatory Commission
(USNRC 1977). Miller and Hoffman (1983) analyzed 54 measurements of
lm from 25 studies, covering various categories of depositing substances
and vegetation growth forms. Values for these measurements range from
2.8 to 34 days, with a geometric mean of 10 days and a GSD of 1.7
• Milk biotransfer factor
Baes et al. (1984) and Ng (1982) provided the only available estimates of
the ingestion-to-milk biotransfer factor for arsenic of 6.0 x 10~5 day/kg,
which is used for the most likely value for Ba^. Because the GSD of the
arsenic biotransfer factors was not reported, the value of 3.8 used for the
GSD of Ba^f for arsenic is assumed, which corresponds to a geometric
mean of 2.5 x 10~5 and values for Ba,,^ ranging from 1.7 x 10~6 to

3.6x10 4. Lognormal distributions have been used to represent biotransfer
factors by CalEPA (1993), McKone and Ryan (1989), and Ng (1982).
Chicken biotransfer factor
Belcher and Travis (1989) provided the only available estimate of the
ingestion-to-chicken biotransfer factor for arsenic of 0.2011 day/kg, which
is used for the most likely value for 83,^,^,. Because the GSD of the
arsenic biotransfer factors was not reported, the value of 3.8 used for the
GSD of Ba^f for arsenic is assumed, which corresponds to a geometric
mean of 0.082 and values for Ba^te, ranging from 0.0057 to 1.2.
Lognormal distributions have been used to represent biotransfer factors by
CalEPA (1993), McKone and Ryan (1989), and Ng (1982).
Body weight (BW)
The same probability distribution for adult body weights used for the
2,3,4,7, 8-PeCDF uncertainty analysis is used.
• Pork intake rate
The site-specific most likely value for IRp^ is 34 g/day. This value and the
cumulative distribution function were extrapolated from a 1987-88 USDA
national food consumption survey (USDA 1993, 1982), as summarized in
Chapter VI. Based on this survey, the upper and lower bounds of the 95
percent confidence interval for pork intake rates are 169 and 3 g/day,
respectively. The ingestion rate of pork is expected to be related to body
weight. To account for this relationship, a correlation coefficient between
and BW of 0.9 is assumed.
The most likely values and PDFs of the secondary influential parameters are summarized
in Appendix V-21.
The fate and transport model is coupled with the software package ©RISK (Palisade
Corporation, Version 3.1), which is used to perform the propagation of the input
parameter uncertainties through the model. A Latin hypercube sampling analysis is
performed to estimate the uncertainties associated with the risk assessment of indirect
exposure to 2,3,4,7, 8-PeCDF and arsenic for adult subsistence farmers. The LHS
model is iterated until it converges on a stable output distribution, defined as a change of
less than 1.5% in the average percentile values, the mean of the distributions, and the
standard deviations.

-------
For indirect exposure to 2,3,4,7,8-PeCDF, the maximum point estimate of risk to
adult subsistence farmers in subarea El is 1.9xlO~6 (Chapter Vm), which is estimated
to be at approximately the 60th percent confidence level of the derived probability
distribution. The statistical parameters of this distribution are:
• Percent Confidence Levels:
5th 5.8X10-*
10th 1.1 X10-7
25th 3.3xlO~7
50th 1.2X10'6
75th 4.5 XKT6
90th 1.6X10'5
95th 3.2XHT5
Convergence to this output distribution occurred after 3,200 iterations.
For indirect exposure to arsenic, the maximum point estimate of risk to adult
subsistence fanners in subarea El is 9.9 x 10~9, which is estimated to be at
approximately the 70th percent confidence level of the derived probability distribution.
The statistical parameters of this distribution are:
• Percent Confidence Level:
5th 7.2 XlQ-10
10th 1.1X10-9
25th 2.4 xlO-9
50th 5.6 xlO'9
75th 1.4X10-'
90th 3.0XKT8
95th 5.1X10'8
Convergence to this output distribution occurred after 2,700 iterations.
To assess the potential impact of parameters not included in the variance
propagation, the output distribution is recalculated for 2,3,4,7,8-PeCDF and arsenic
using both the primary and secondary influential parameters. For the secondary
parameters, uniform distributions are assumed, using the ranges specified in Table IX-1.
The resulting output distributions for 2,3,4,7,8-PeCDF and arsenic risks do not differ
significantly from the output distributions derived using only the primary input
parameters. The 50 percent confidence levels do hot differ by more than 3 % for

-------
2,3,4,7,8-PeCDF and 3% for arsenic; the 95 percent confidence levels do not differ by
more than 7% for 2,3,4,7,8-PeCDF and 2% for arsenic. The location of the maximum
point estimates of risk in the derived probability distributions is not affected by the
secondary input parameters. Therefore, the parameters not included in the variance
propagation are not expected to affect the output distributions by more than
approximately 10%.
£. Major Assumptions and Limitations
The accuracy of this uncertainty analysis is dependent on several key assumptions.
These assumptions must be taken into consideration when determining the validity and
limitations of the results presented in this chapter. The major assumptions of the uncertainty
analysis are summarized in Table IX-4.
F. Conclusions
A three-tiered approach to uncertainty analysis is applied to determine the impact of
uncertainty and variability on the HHRA. The uncertainty analysis focuses on two of the
chemicals and exposure pathways identified to pose the greatest carcinogenic health risks.
The resulting probability distributions offer a means of estimating the degree of certainty that
the risk will be below a particular level. Also, by understanding which input parameters
have the greatest impact on the output variables, additional data gaps and research needs can
be identified for improving the accuracy of risk assessments.
Based on the results of this uncertainty analysis, the 95th percent confidence level cancer
risk estimate for indirect exposures to 2,3,4,7,8-PeCDF for the subsistence farmer subgroup
in subarea El is approximately 3 x 10~5. This value is about 15-fold higher than the point
estimate of risk at the point of maximum impact (1.9xlO~6), as presented in Chapter VET.
Accordingly, based on available information and data regarding the key input parameters,
there is only a small probability that cancer risks to 2,3,4,7,8-PeCDF through indirect
exposure pathways for subsistence farmers in subarea El are greater than 3 x 10~5. Given
the contribution of 2,3,4,7,8-PeCDF to overall risks through all pathways, it can also be
concluded that it is unlikely that the total cancer risk for subsistence farmers in subarea El
for all chemicals combined would exceed 1 x 10~4.
The sensitivity analysis for 2,3,4,7,8-PeCDF indicates that the parameters that have the
greatest influence on the cancer risk estimate for this chemical are Henry's constant (H) and
the octanol/water partition coefficient (K^). Both of these parameters are used for
estimating the values of other parameters, such as the root concentration factor (RCF),
soil/water distribution coefficient (Kd,), and volumetric air-to-leaf biotransfer factor (B^,),
among others. The primary influence of H on the risk estimate is through the estimate of

-------
Bvol, which is a key parameter for determining the vapor-phase uptake of 2,3,4,7,8-PeCDF
into vegetation. K^ is also a key parameter for estimating Bvol, as well as determining the
bioaccumulation potential of 2,3,4,7,8-PeCDF in animal tissue. Therefore, .the most
effective approach to reducing the uncertainty in the risk estimate for 2,3,4,7,8-PeCDF
would be to develop improved data for H and K^.
Similarly, for arsenic, the 95th percent confidence level cancer risk estimate for indirect
exposures (5.1 xlO~8) is calculated to be approximately 5-fpld higher than the point estimate
of risk at the point of maximum impact (9.9 xlO"9), as presented in Chapter VIE. Based on
the estimated 95th percent confidence level risk, it can be concluded that it is unlikely that
indirect exposures to arsenic would contribute significantly to overall risks associated with
stack emissions.
The sensitivity analysis for arsenic indicated that the parameters that have the greatest
influence on the cancer risk estimate for this metal are the plant/soil bioconcentration factor
(reproductive portion) (Br) and the beef biotransfer factor (Ba^f). The location of maximum
risk due to arsenic is the region of maximum wet deposition. Thus, Br, which determines
the bioconcentration of arsenic in the reproductive portions of vegetation, and Ba^f, which
determines the subsequent biotransfer of arsenic into animal tissue, would be expected to
have a major influence on the uncertainty in the risk estimate. Therefore, the most effective
approach to reducing the uncertainty hi the risk estimate for arsenic would be to develop
improved data for Br and

The uncertainty analysis is limited to two specific
cases: the organic chemical and the metal estimated
to pose the greatest carcinogenic health risks to the
most highly exposed subgroup via indirect exposure
pathways (i.e., indirect exposure to 2,3,4,7,8-PeCDF
and arsenic by adult subsistence farmers in subarea
El). The analyses of these two cases are assumed to
be representative of the overall uncertainty associated
with the HHRA, and may serve as a basis for
reasonable approximations of the uncertainty
associated with the overall risk estimates.
In accordance with EPA guidance (U.S. EPA 1995a), a
detailed quantitative uncertainty analysis is not performed for
the entire HHRA; i.e., the uncertainty in the risk estimates for
exposure to every chemical to every population subgroup
through every exposure pathway at every location is not
quantitatively assessed. As discussed in Chapter VIII, indirect
exposure to 2,3,4,7,8-PeCDF represents approximately 32%
of the total risk to subsistence farmers. Total dioxins and
furans represent approximately 67% of the total risk. Based
on these results, 2,3,4,7,8-PeCDF can be expected to be a
reasonable indicator of the uncertainty in the total risk
estimate.

For the specific cases evaluated in the uncertainty
analysis, a variance propagation is performed using a
limited subset of the input parameters (i.e., the
"primary" influential parameters). The input
parameters not selected in the sensitivity analysis
were assumed to have a small impact on the results
of the variance propagation.
The "primary" influential parameters are selected based on the
results of a sensitivity analysis. This assumption is validated
by repeating the variance propagation including an addition set
of "secondary" influential parameters. The inclusion of the
secondary input parameters does not change the output
distributions by more than approximately 7%. Therefore, the
exclusion from the variance propagation of all the input
parameters that are not selected in the sensitivity analysis is
not expected to change the output distributions by more than
10%.

The emissions data collected during the February '
1994 trial bum and 22 performance test runs (August
1993 to August 1994) are assumed to represent the
expected range of long term operating conditions and
waste feeds from the WTI incinerator.
The performance tests were conducted using actual facility
waste feeds and a wide range of operating conditions.
Therefore, provided future waste feed compositions do not
contain substantially greater quantities of any particular
constituent, the emission rates are expected to be within the
range used in this uncertainty analysis.

Brominated compounds are assumed not to exceed
one third of the chlorinated aromatics in the waste
feed.
Based on a review of the waste profiles for WTI's first nine
months of operation, quantities of brominated compounds in
the waste feed are approximately one twentieth of the
chlorinated compounds. Therefore, this is expected to be a
conservative assumption, resulting in an overestimate of the
quantity of halogenated compounds being emitted from the
facility.

Lognormal distributions are assumed for most of the
input parameters. In particular, parameters that are

Based on published data for most of these parameters, this is
considered to be a reasonable assumption, and has been
adopted in several other uncertainty analyses (McKone 1994;
CalEPA 1993; McKone and Ryan 1989).

X. SUMMARY AND CONCLUSIONS
This volume of the WTI Risk Assessment presents a site-specific, multipathway
assessment of human risks posed by emissions from the WTI facility. The primary processes
that generate chemical emissions at the facility include:
• The incineration process, where hazardous waste is combusted in a rotary kiln
incinerator, and chemical constituents generated during combustion are
released along with the flue gases from the incinerator stack; and
• The waste feed handling and storage process, where some of the volatile
constituents present in the waste feed may be released into the atmosphere in
the form of fugitive emissions.
As discussed in Volume HI, emissions from the incinerator stack are estimated
primarily by conducting stack measurements. Dioxins and furans are identified as the
constituents of primary concern in stack emissions. Fugitive emission rates of volatile
constituents in the waste feed are estimated using conservative assumptions and models that
likely overstate emissions, and are based on the waste feed composition, as determined from
an analysis of wastes received during WTI's first year of operation.
As discussed in Volume IV, the ISC-COMPDEP model is used to simulate the
atmospheric transport of facility emissions, and to predict vapor concentrations and particle
deposition in the vicinity of the site. The ISC-COMPDEP model was modified to
incorporate local meteorological conditions that are influenced by the complex terrain in
which the site is located. Chapter VI of this volume discusses the appropriate fate and
transport models that are used to estimate concentrations in environmental media to which
individuals in the site vicinity may be exposed. These media include air, soil, water, and
food products such as vegetables and meat.
A study area for the risk assessment is defined to extend over a 12 kilometer (km)
radius from the facility, which encompasses the area most affected by stack emissions. The
study area is divided into 12 subareas, three subareas in each north, south, east and west
direction. The boundaries of the subareas are defined by concentric rings surrounding the
facility at radii of 3 km, 7 km, and 12 km.

-------
Subgroups of the populations in the site vicinity are identified to adequately reflect
exposures to the entire population within the study area. The population subgroups include
adult and child residents and fanners, as well as subgroups such as subsistence farmers and
school children that may be susceptible to higher exposures as a result of their particular
activity patterns.
Risk to the identified subgroups are estimated by evaluating the potential for cancer
risks and noncancer effects from exposure to facility-related chemicals. Population risks are
also evaluated based on estimates of the number of individuals in each subgroup, taking into
consideration the differing levels of exposure of the individual subgroups based on their
particular activity patterns and locations with respect to the site.
The uncertainty associated with individual steps of the risk assessment process are
combined in a Monte Carlo analysis, to provide estimates of the likely range of cancer risks
for the most highly exposed subgroup, the subsistence farmer, and the probability of
individual subsistence farmers experiencing risks at different levels within this risk range.
The following is a summary of the Human Health Risk Assessment results.
Stack Emissions
• Dioxins and furans are identified as the primary constituents of concern in
stack emissions, based on the levels of measured emissions, the likely extent
of accumulation in food, and the toxicity of this class of chemicals.
• The expected dioxin and furan emissions from the facility expressed as toxicity
equivalents is estimated to be 1.3 x 10'9 g/s.
• Use of the air dispersion model, the ISC-COMPDEP model, is considered a
reasonable means of predicting the off-site impacts of facility emissions with
modifications made to the model to allow incorporation of meteorological data
collected at multiple heights at the WTI facility and at another location within
the Ohio River Valley approximately 10 miles away.
• Particle emissions consist of fine particles less than 10 micrometers (/im) in
diameter, with 70 percent of the particles less than 1 /*m in diameter. These
emissions are not predicted to result in exceedances of the National Ambient
Air Quality Standards (NAAQS).

-------
The air dispersion model predicts the highest impacts to occur within one
kilometer of the facility, primarily in the east-west direction. Particle
deposition as a result of precipitation scavenging (wet deposition) is predicted
to be the principal deposition mechanism.
The consumption of meat (beef, pork, and poultry) and eggs from locally
raised livestock, and consumption of milk and dairy products (cheese, milk
desserts, yogurt, cream, and butter) from locally raised cows are determined to
be the principal pathways of exposure to WTI stack-related chemicals. In
addition, consumption of mother's milk is a significant pathway of exposure
for breast-feeding infants.
The subsistence farmer and child are identified as the subgroups with the
highest estimated risks.
Cancer Risks
The estimated average total cancer risk (direct and indirect) for each of the
population subgroups is less than 1 x 10"5, or 1 in 100,000. The highest
subarea cancer risk of 1 x 10"6 is estimated in subarea El (the nearest subarea
to the east of the site) for the subsistence farmer. The estimated average
cancer risk for the subsistence farmer child in subarea El is also
1 x 10-6.
The cancer risks for the adult and child farmer are estimated to be
approximately 2 to 3-fold lower than the subsistence fanner adult and child.
The cancer risks for the adult and child resident are estimated to be
approximately 10-fold and 3-fold lower than the subsistence fanner adult and
child, respectively.
The compound 2,3,4,7,8-PeCDF (a chlorinated furan) is identified as the
chemical primarily contributing to the estimated cancer risk for the indirect
pathways, with the exception of breast milk ingestion. Approximately 38
percent of the risk to the subsistence farmer is accounted for by 2,3,4,7,8-
PeCDF. Dioxins and furans account for approximately 76 percent of the
estimated risk to the subsistence farmer.

-------
• High-end (approximately 90 percentile) exposure for the subsistence farmer is
estimated to provide a measure of the possible variation in behavioral
characteristics (e.g., inhalation rates) of individuals in this subgroup. The
high-end cancer risk to the subsistence fanner is 7 x 10"6 for this subgroup in
subarea El, more than five times higher than the average risk.
• To provide an estimate of the variability in exposures within a subarea due to
differences in exposure concentrations with location within the subarea, an
evaluation of the risk at the point of maximum impact within each subarea is
estimated. In general, this risk is approximately three to four times higher
than the average risk, i.e., a cancer risk of 4 x 10"6 is estimated for the
subsistence farmer in subarea El. The likelihood, however, of a subsistence
farmer being located at the point of maximum impact is extremely small. The
risks at the point of maximum impact, therefore, are hypothetical and
presented for illustrative purposes only.
• An uncertainty analysis is performed for 2,3,4,7,8-PeCDF, which is the most
significant contributor to the estimated cancer risk for the subsistence farmer
subgroup at the point of maximum impact hi subarea El. Based on the results
of this uncertainty analysis, there is an approximately 95 percent likelihood
that the cancer risk estimate for indirect exposures to 2,3,4,7,8-PeCDF for a
subsistence farmer in subarea El is below 3 x 10"5. This value is about 15-
fold higher than the point estimate of 2 x 10"6 for the subsistence farmer.
Accordingly, based on available information and data regarding the key input
parameters, there is only a small probability that cancer risks due to exposure
to 2,3,4,7,8-PeCDF through indirect exposure pathways for subsistence
farmers in subarea El are greater than 3 x 10~5.
Noncancer Effects
• The estimated average noncancer hazard indices (His) are below 1.0 for all
population subgroups. The total average noncancer HI values (direct plus
indirect) estimated in subarea El for the subsistence farmer and the subsistence

child, approximately 1 to 2-fold. The noncancer HI values for the adult and
child resident are estimated to be also approximately 1 to 2-fold lower than the
subsistence farmer adult and child.
Hexachlorophene is estimated as the chemical primarily contributing to the
estimated noncancer HI value. Approximately 38 percent of the estimated
noncancer HI value for the subsistence farmer child is accounted for by this
compound. Of the total estimated hexachlorophene HI value, meat and dairy
ingestion account for almost the entire value (50 percent each).
The estimated high-end HI value for the subsistence farmer child in subarea El
is approximately one to two times the average HI value (i.e., the estimated
high-end HI value for the child is 0.1 hi subarea El).
Other Subgroups
The estimated average cancer risks for breast feeding infants of subsistence
farmers in subarea El is 2 x 10"6. The non-dioxin organic chemicals
contribute approximately 66 percent of the total estimated risk with
benzo(a)pyrene accounting for 37 percent of the total risk. Dioxins and furans
account for approximately 34 percent of the total estimated risk.
Extremely low cancer risks and noncancer HI values are estimated for
subsistence fishermen fishing in the Ohio River and Little Beaver Creek,
which is located in subarea N2. The maximum risk and HI value are
estimated to be less than 6 x 10'8 and less than 4 x 10'3, respectively. A
noncancer HI value of 0.004 is estimated for the subsistence fisherman fishing
Tomlinson Run Lake located in subarea S3.
Other Pollutants
The predicted concentrations of priority pollutants such as sulfur dioxide,
nitrogen oxides, hydrogen chloride, particles and lead are substantially below
the National Ambient Air Quality Standards (NAAQS).

Fugitive Emissions
The average cancer risks from inhalation exposure to organic vapor fugitive
emissions for residents within a radius of 2,000 feet from the site is estimated
to be in the range of 5 x 10~7 to 2 x 10*. These cancer risk estimates are
based on very conservative (overstates actual) estimates of emissions from the
identified sources of fugitive emissions, particularly the wastewater tank and
leakages within from the organic waste feed tank building.
The estimated noncancer HI values are similarly overstated and range between
0.01 and 0.07.
Average inhalation cancer risks associated with fugitive ash emissions are
estimated to be below 5 x 10~8. HI values do not exceed 7 x 10"*.
Average indirect cancer risks associated with fugitive ash emissions are
estimated to be below 4 x 10~u. HI values for indirect exposure do not exceed
5 x 10-6.

NOTES:
NR = Not required to estimate the partitioning factor.
(a) = The melting point is used in estimating the partitioning factor if it is greater than ambient temperature (20 degree C).
(b) = Fraction partitioning onto particle.
(c) = PAHs with very low vapor pressures are assumed to be emitted as particles.
(d) = The literature qualitatively states that the vapor pressure for this chemical is "not significant"
The vapor pressure is assumed to equal 0.
(e) = All inorganic chemicals except mercury are assumed to be emitted as particles,
therefore, a vapor pressure is not required.
Other constants needed to estimate the partitioning factor
St = 3.5E-06 cmA2/cmA3
c= 1.7E-04 atm-cm

INTRODUCTION
The WTI Risk Assessment Project Plan identifies a number of subgroups of the
population that may be exposed directly or indirectly to emissions from the facility,
including:
• Adult non-farming residents living in homes with gardens;
• Child non-farming residents living in homes with gardens;
• Adult non-farming residents living in homes without gardens;
• Child non-farming residents living hi homes without gardens;
• Adult farmers whose diet consists partially of homegrown food products
(e.g., meat, milk, vegetables);
• Farm children whose diet consists partially of homegrown food products;
• Adult farmers whose entire diet is homegrown (referred to as subsistence
farmers); and,
• Subsistence farm children.
In addition to these subgroups, groups of individuals are identified as members of a
special population segment or individuals who may be highly exposed because of then-
particular activity patterns. These groups include:
• Children (7 to 12 years old) who attend school in the area;
• Breast-feeding infants .(assumed to be all children under 1 year old); and,
• Subsistence fishermen (recreational fishermen who obtain a significant portion
of then- diet from fish hi local bodies of water).
During the peer review process conducted for the WTI Risk Assessment Project Plan,
the Exposure Assessment Work Group identified a number of additional subgroups of the
exposed population that may be at a higher risk due to behavior patterns, proximity to the
facility, or sensitivity. The purpose of this appendix is to evaluate each of the potential
subgroups identified by the Exposure Assessment Work Group and provide a rationale for
omitting or including each subgroup hi the exposure assessment for the WTI Risk
Assessment.

-------
EVALUATION OF ADDITIONAL HIGH-END SUBGROUPS
The Exposure Assessment Work Group of the peer review committee indicated that
the following subgroups should be evaluated for inclusion hi the WTI Risk Assessment:
I
• Children who live near the facility and attend school near the facility;
• Individuals who work at WTI;
• Adults who live and work near WTI;
• Elderly individuals hi the study area;
• Hunters of deer and waterfowl; and,
• Other potentially high-end exposure subgroups.
The rationale for including or omitting each of these subgroups is provided hi the following
sections.
Live and Attend
As noted earlier, the proposed methodology for estimating exposure accounts for
varying activity and behavior patterns by dividing the exposed population into 11 subgroups
and accounts for location with respect to the WTI facility by identifying isoconcentration
subareas. One of the subgroups of the exposed population identified hi the WTI Project Plan
is children (7 to 12 years old) who attend school in the area. This exposure subgroup was
developed to include children living and attending school hi the study area and will include
children hi subareas near the facility and farther away. Therefore, this additional subgroup
is already included hi the subgroups identified hi the Project
Plan.
Individuals Who Work at WTI
It is possible that individuals who work at the WTI facility may be exposed to
chemicals hi the workplace which may result in incidental transport of contaminants to off-
site locations, resulting hi potential exposures to off-site individuals (e.g., family members).
Quantitative evaluation of worker exposure and transport of chemicals off-site by workers is
beyond the scope of the WTI Risk Assessment, however, WTI worker exposure and
migration of contaminants by workers are addressed qualitatively hi the uncertainty section of
the WTI Risk Assessment.

x-- Adults
C .
Adult residents living and working in the study area are one of the population
subgroups identified in the WTI Project Plan. Exposure factors for this subgroup reflect the
possibility that an individual may be exposed to emissions from the WTI facility either at
home or at a place of employment. Therefore, this subgroup is already included hi the
subgroups identified hi the Project Plan.
Elderly Individuals
The peer reviewers noted that the population hi the vicinity of the WTI facility has a
higher than expected concentration of elderly individuals; therefore, the reviewers
recommended that this subgroup be considered for inclusion in the WTI Risk Assessment.
Based on a review of 1990 census data for the counties in the vicinity of the WTI facility,
elderly populations do not appear to be above average.
In addition, based solely on activity patterns or location, there is no reason to believe
that elderly individuals will necessarily be on the high-end of the exposure distribution,
unless specific activities (e.g., subsistence fishing, subsistence farming) cause them to be
C exposed to a greater degree than other population subgroups. These types of potentially
V high-exposure activities are considered hi the WTI Project Plan; therefore, a specific
subgroup for elderly individuals is not warranted.
It is possible that elderly individuals may be on the high-end of the risk distribution
because of a higher than expected sensitivity to contaminants to which they may be exposed.
Toxicological data are not available, however, to effectively evaluate elevated sensitivity to
chemicals by elderly individuals as a separate analysis. Consequently, estimates of
toxicological potency incorporate safety factors to account for the presence of sensitive
individuals hi the population (e.g., elderly people). Therefore, this subgroup is not
considered separately hi the WTI Risk Assessment.
Hunters of Deer and Waterfowl
It is possible that deer and waterfowl that live hi the study area may be exposed to
contaminants emitted from the WTI facility. Potential effects to such species are be
addressed in the Sceening Ecological Risk Assessment for the WTI facility. As part of the
exposure assessment for the WTI Risk Assessment, hunters who may be exposed indirectly
^ to facility emissions due to consumption of exposed deer or waterfowl are evaluated
V qualitatively to estimate the likelihood that this type of exposure is significant (i.e., more
Volume V External Review Draft
Appendix V-5 3 Do Not Cite or Quote
-------
significant than exposure by other food consumption pathways, such as subsistence beef or
fish consumption). For example, estimates of deer hunting hi the vicinity of the WTI facility
are developed to evaluate the likelihood that deer meat consumption may be of a greater
concern than beef consumption. It is unlikely, however, that this subgroup will be exposed
to a significantly greater degree than other high-end subgroups such as the subsistence
farmer.
Other Potentially High-end Exposure Subgroups
No additional potential exposure subgroups were identified that may be exposed
significantly but were not adequately represented by subgroups considered hi the WTI Risk
Assessment. It is believed that the exposure subgroups evaluated in the WTI Risk
Assessment largely reflect the population in the study area and addition of other groups
would not substantially alter the results of the assessment.
SUMMARY
Based on the peer review of the WTI Project Plan, several possible additional high-
end exposure subgroups were identified. Each of the recommended subgroups were
evaluated regarding possible inclusion hi the WTI Risk Assessment, with the following
results:
1) Children who live and attend school near the facility - This subgroup is already
considered hi the WTI Project Plan.
2) Adults who work at WTI - Quantitative assessment of exposure to workers at the WTI
facility itself is beyond the scope of the WTI Risk Assessment, but is discussed
qualitatively hi the WTI Risk Assessment.
3) Adults who work and live near WTI - Adult residents are identified hi the Project
Plan and exposure to emissions from WTI, regardless of location (i.e., work, home,
or school), is evaluated for this subgroup.
4) Elderly individuals - Elderly individuals are not necessarily at the high-end of the
exposure distribution, and although elderly people may be at the high-end of the risk
distribution due to increased lexicological sensitivity, such increased sensitivity is
accounted for hi the Toxicological Assessment.
5) Hunters of deer and waterfowl - It is possible that hunters who kill and consume deer
or waterfowl from the study area may be exposed to emissions from the WTI facility.
It is unlikely, however, that this type of exposure will be greater than exposure from

-------
other potentially high-end activities (e.g., subsistence fishing or fanning).
Nonetheless, a qualitative analysis is performed as part of the WTI Risk Assessment
to evaluate the possible addition of this subgroup.
6) Other potentially high-end exposure subgroups - No additional potential high-end
exposure population subgroups were identified. The subgroups identified in the WTI
Project Plan are believed to include a significant fraction of the exposed population in
the study area.

RECREATIONAL FISHING DATA
The state Departments of Natural Resources (DNR) in Ohio, West Virginia, and
Pennsylvania were contacted to obtain recreational fishing data. Two recently conducted
recreational fishing studies were identified: 1) a joint study conducted in 1992 by the Ohio
DNR and West Virginia DNR (ODNR 1994a); and 2) a study being conducted for the
Pennsylvania DNR (Terrestrial Environmental Systems 1994). Sufficient data to estimate the
number of anglers or typical fish harvest in this area were not available from the
Pennsylvania study at the tune of this assessment.
The joint Ohio/West Virginia DNR recreational fishing study (ODNR 1994a) was
conducted to identify the amount of fishing and the types of fish being caught along the Ohio
River between the Ohio/Pennsylvania border (Ohio River Mile 40.1) and Greenup Dam, 300
miles downstream (ORM 341). This 300-mile study area was subdivided into 32 survey
areas, which include survey points (embayments and tailwaters), and pools. Four of the 32
survey areas (locations #1 to #4) are hi the general vicinity (30-kilometer radius) of the WTI
facility (located at ORM 41.5). These four survey areas are assumed to be representative of
the Ohio River in the vicinity of the WTI facility. The four survey areas cover the entire
stretch of the Ohio River from the Ohio/Pennsylvania border to Steubenville, Ohio (ORM
40.1 to ORM 69.5). Data from survey areas located farther down river (ORM 69.5 to ORM
341) are also evaluated as a basis for comparison.
The DNR study was conducted between April and November 1992. Very little
fishing occurs between December and March; therefore, the data collected hi this study are
assumed to reflect annual data. Table 1 summarizes the recreational fishing data obtained
from the Ohio/West Virginia DNR study (ODNR 1994a).
RESULTS
Although the Ohio/West Virginia DNR study provides significant data concerning the
types of fish being caught and kept along the Ohio River, sufficient data are not available to
characterize the relationship between fishing practices and fish consumption by the local
population. However, data contained hi the Ohio/West Virginia DNR study and information

obtained from local fish and wildlife agencies indicate that fish raised hi the vicinity of the
WTI facility are not a significant source of food for the typical local resident1. Information
used to support this assessment include the following:
• No commercial fishing operations operate hi the vicinity of the WTI facility.
Fish and wildlife agencies in Ohio, West Virginia, and Pennsylvania were contacted
regarding the presence of commercial fishing (i.e., operations or individuals that catch
fish and distribute to local supermarkets and restaurants) hi the vicinity of the WTI
facility (ODNR 1994b; West Virginia Fisheries 1994; PFBC 1994a). Although
several fish farms are located hi the general vicinity of WTI, the fish and wildlife
officers contacted indicated that the fish raised hi these operations are not sold for
consumption, but are used as stock fish hi local water bodies. None of the officials
contacted had any knowledge of any commercial fishing operations in the WTI area;
therefore, all local fish consumption must be derived from fish caught by individual
fishermen.
• Only a small fraction of the resident population hi the vicinity of WTI fish.
Agencies hi Ohio (ODNR 1994c), West Virginia (WVDNR 1994), and Pennsylvania
(PFBC 1994b) responsible for fishing licenses were contacted for information
regarding the number of fishing licenses sold hi counties surrounding the WTI
facility. Based on data provided by these agencies, the total number of annual
resident fishing licenses hi the 11 counties surrounding the WTI facility is
approximately 180,000. The total population hi these 11 counties is over 2.5 million,
based on 1990 census data. Therefore, approximately seven percent of the population
in the WTI area is legally permitted to fish. Although it is possible that some
individuals may fish without a license, survey data collected hi the Ohio/West
Virginia DNR fishing study (ODNR 1994a) indicate that only 3 percent of the anglers
surveyed did not have licenses. Although these individuals who fish will be exposed,
these data indicate that a significant fraction of the entire local population does not
fish; therefore, it is unlikely that a significant fraction of their fish diet is derived
from local sources (i.e., an average individual's fish diet does not contain a
significant fraction of locally caught fish). As noted earlier, risks to the fishing
population are represented hi this assessment by the subsistence fisherman scenario.
1 This is not meant to imply that subsistence fishing is or is not occurring hi this area.
Subsistence fishermen are considered separately from local residents hi the WTI Phase II
Risk Assessment.

• The amount of fish caught locally and kept is unlikely to be significant.
According to the results of the Ohio/West Virginia DNR study (ODNR 1994a),
approximately 400,000 fish were caught and 63,000 fish were kept along the 30 miles
of the Ohio River between the Ohio/Pennsylvania border and Steubenville, Ohio
during 1992. As indicated hi Table 1, almost 90 percent of the fish kept by anglers
were of the bass family, which are generally relatively small fish (fish size data
collected during the ODNR study indicates an average bass length of between 7 and
13 inches). The Ohio River Valley Sanitation Commission (ORSANCO) conducted
an electrofishing survey (between ORM 21.6 and ORM 55.5) during 1991 to 1993
(ORSANCO 1994) that provides the average weight of fish from the Ohio River
corresponding to various size ranges. Based on these data, it is estimated that fish in
the size ranges provided in Table 1 range from 50 to 650 g (0.1 to 1.4 pounds) with
an average of 180 g (0.4 pounds). As a conservative estimate, it is assumed that the
average fish caught along the Ohio River yields no more than 0.4 pound of fish for
consumption. The 63,000 fish caught along the 30 miles of the Ohio River (survey
locations #1 to #4) in the vicinity of WTI in 1992, therefore, resulted hi no more than
25,000 pounds of fish per year available for consumption. Even if the high-end of
the weight range is assumed, no more than 90,000 pounds of fish per year from the
Ohio River is available for consumption. The 25,000 pounds of fish caught locally,
therefore, corresponds to less than 0.2 grams of fish consumed per day for the fishing
population (based on the number of fishing licenses and assuming the fish is not
distributed amongst a larger population). Furthermore, the 25,000 pounds of fish
corresponds to less than 0.01 g/day of locally caught fish for local residents
(assuming the fish is distributed evenly amongst all local residents in the 11-county
area near WTI). These consumption rates of locally caught fish are insignificant
compared to the average fish consumption rate of 11 g/day for residents.
It should be noted that fishing is likely to occur at locations throughout the area
around the facility (i.e., other than the Ohio River), including smaller rivers, lakes, and
ponds. Discussions with local fish and wildlife officers (ODNR 1994b; West Virginia
Fisheries 1994; PFBC 1994a) indicate, however, that the Ohio River is likely to be the most
significant source of fishing in the area. Therefore, considering the approximate size of the
fishing population (180,000) and the local population (approximately 2.5 million), it does not
appear that a significant fraction of local residents' fish diet comes from fish caught locally.
In summary, the data available from the Ohio/West Virginia DNR fishing study
(ODNR 1994a) and the information obtained from discussions with fish and wildlife officials
familiar with fishing practices hi the vicinity of the WTI facility indicate that fish from local
Volume V External Review Draft

-------
waters are unlikely to contribute a significant fraction of the fish diet for local residents.
Therefore, exposure to contaminants that are released from the WTI facility and
bioaccumulate hi fish are not considered hi the WTI Risk Assessment as a potential exposure
pathway for the typical local resident. However, because individuals may exist hi the study
area who represent high-end exposure to contaminants hi fish, a subsistence fisherman
scenario is considered hi the Risk Assessment. Uncertainties associated with not including
the resident fish consumption exposure pathway are discussed hi the uncertainties -section of
the Risk Assessment. An additional source of uncertainty may arise because this assessment
is not designed to estimate contaminant exposure to individuals who consume a specific
species of fish (e.g., carp) as a predominant portion of their diet. Although certain species
(e.g., carp) may have a relatively greater lipid content, resulting hi relatively higher
contaminant concentrations, this assessment estimates concentrations of contaminants in fish
based upon a reasonable estimate of several factors, including the lipid content of fresh water
fish.

Receptors are exposed to stack gas chemicals by both direct and indirect pathways.
Direct exposure occurs through inhalation of vapors and particles in the air. Indirect
exposure occurs as a result of dry and wet deposition of particles and vapor onto the soil,
migration of chemicals into vegetation, animals, and surface water, and subsequent human
ingestion of soil, vegetation, animal products, fish, and surface water that has been affected
by stack gas emissions. Exposure concentrations in affected media are estimated using fate
and transport models that simulate the transport of stack gas chemicals in the environment.
These models are based on U.S. EPA (1990a, 1993, and 1994a) guidance; however, it
should be noted that, in several cases, the chemical fate and transport models are based on
limited data. The uncertainties in applying these models to a broad spectrum of chemicals
are discussed in the uncertainty section of the Human Health Risk Assessment.
This appendix presents the fate and transport model equations and inputs used to
estimate environmental concentrations. Site-specific values are used wherever possible,
otherwise, U.S. EPA recommended default parameters are used. This appendix is divided
into six sections, corresponding to the six different media for which concentrations are
needed to estimate indirect human health risks: 1) soil, 2) vegetation, 3) meat, eggs, and
milk, 4) surface water, 5) fish, and 6) mothers' milk. Physical/chemical values for the
chemicals of concern and site-specific parameters are presented in Tables 1 to 4. It should
be noted that because mercury is assumed to exist as a vapor, additional parameters are
required to evaluate its fate and transport. These parameters are listed in the footnote in
Table 3.
As discussed in Volume n, the key assumptions that are used in performing the WTI
Risk Assessment are identified. Table 38 summarizes the key assumptions that are used in
developing estimates of exposure concentrations in the various media. The table indicates the
basis for the assumptions listed, the estimated relative magnitude of the assumption's effect
on the overall risk assessment, and the direction of the effect, if known.

1. Estimation of Soil Concentrations
It is assumed that a portion of each of the stack gas chemicals is deposited on surficial
soils in the study area due to dry and wet deposition of particles and vapor. The
concentration of chemicals in surficial soil is required to estimate human exposure to
chemicals in soil through soil ingestion and dermal contact with soil, to predict uptake in
vegetation for human consumption and grazing animals, and to estimate the concentration in
surface water. Tables 5 to 11 are used to estimate chemical concentrations in soil. Soil
concentrations are estimated for surface (one centimeter) soils and root zone (20 centimeters)
soil (U.S. EPA 1990a). In addition, soil concentrations within the upper 10 centimeters are
estimated as an input to estimating surface water concentrations (U.S. EPA 1994a), assuming
an agricultural watershed, which could have some tilled and some untilled soils. These soil
concentrations are based on deposition rates of chemicals of concern assuming complete
mixing within the soil layer of interest (surface, root zone, or average) and continuous
operation of the facility over a period of 30 years.
As presented in Table 5, various parameter values are needed to estimate soil
concentrations. Deposition rates and vapor-phase air concentrations used in the equation are
determined from air dispersion modeling. The deposition flux of vapor is estimated using
the equation in Table 6. The soil loss constant (kse) is determined as the sum of four
independent processes: leaching, soil erosion, surface runoff, and degradation (abiotic and
biotic) (Table 7). Losses due to leaching (ksl), soil erosion (kse) and surface runoff (ksr) are
estimated using the equations presented in Tables 7, 8, and 10, respectively. Losses due to
degradation (ksg) are empirical and are determined from a review of the literature. It is
conservatively assumed that additional losses due to volatilization do not occur because given
all the opportunity for volatilization to occur during atmospheric transport, once deposited,
additional volatilization losses from the soil are not expected.

2. Estimation of Vegetation Concentrations
The chemical concentration in vegetation is necessary to estimate human exposure to
chemicals through ingestion of vegetation (i.e., vegetables and fruit) as well as to estimate
the uptake of chemicals by animals that feed on the vegetation (i.e., grain, forage, and
silage). Stack gas chemicals may bioaccumulate in plants through three mechanisms: uptake
by roots, direct deposition on exposed plant tissues, and air-to-plant transfer of vapor-phase
chemicals. These mechanisms are discussed more fully by U.S. EPA (1990a and 1994a).
The magnitude of chemical uptake by vegetables is dependent on the type of vegetable
and its potential for exposure to the atmosphere. For example, contaminant deposition onto
leafy vegetables is more likely to occur than onto vegetables that are protected from the
atmosphere, such as com or root vegetables. Similarly, the uptake of chemicals from the
soil will differ for below ground and aboveground vegetables. Therefore, four types of
vegetable classes are considered in the Human Health Risk Assessment: leafy vegetables
(e.g., lettuce, broccoli); aboveground protected vegetables (e.g., corn, peas); aboveground
exposed (e.g., tomatoes, green peppers); and root vegetables (e.g., carrots, onions).
Assumptions for each of these classes of vegetables are used in Tables 12 to 22 to estimate
concentrations of chemicals in vegetables.
The total concentration of a chemical in a given plant (CV) is due to root uptake (PrJ,
direct deposition (Pdj), and air-to-plant transfer (Pv;) as shown in Table 12. Concentrations
of leafy, aboveground exposed and aboveground protected vegetables are calculated in dry
weight. Because ingestion rates are based on fresh weight, the dry weight vegetable
concentration is converted to a wet weight concentration by multiplying by (1-water fraction),
as shown in Table 12. The concentration in root vegetables is calculated in wet weight so a
similar conversion is not necessary. Additionally, dry weight concentrations are needed for
grain, forage, and silage precluding the need for a comparable conversion.
Calculation of the total plant concentration is different for aboveground and below
ground vegetation and is described below. As shown in Table 13, chemical concentration
from root uptake (PTj) for aboveground vegetation (i.e., aboveground exposed and protected
vegetables, and leafy vegetables) is dependent on the soil concentration (CS) and a chemical-
specific plant/soil bioconcentration factor (Br^. Baes et al. (1984) presents bioconcentration
factors for all the metals. For organic chemicals, the bioconcentration factors are calculated
using an equation developed by Travis and Arms (1988) and presented in Table 14.
For below ground vegetation (i.e., root vegetables), Pr{ is estimated by the method
developed by Briggs (1982) and shown in Table 15. Briggs (1982) developed a regression
equation dependent on the octanol/water partition coefficient (KoJ to calculate root
concentration factor (RCFj) values. This equation is presented in Table 16. VG^ is a factor
Volume V External Review Draft
Appendix V-7 22 Do Not Cite or Quote
-------
introduced into the calculation of contaminant concentrations to reflect the reduced
translocation of compounds in bulky, below ground vegetables, such as carrots and potatoes
(U.S. EPA 1994a). In general, the contaminant concentrations measured in the barley roots
of the Briggs (1982) experiments would be representative of the levels of compounds in the
outer few millimeters of below ground vegetation, but much higher than the average
concentration in the whole vegetable. Thus, a VGtg value of 0.01 is used for all compounds
(U.S. EPA,1994c). ,
The factors related to the plant concentration attributable to direct deposition on exposed
plant tissues (Pdi) are presented in Table 17. The site-specific parameters are presented in
Table 17. The wet and dry deposition rates are obtained from the air dispersion modeling.
Fw is the fraction of wet deposition that adheres to plant surfaces and is assumed to equal
0.6 for all organics and 0.46 for all metals, according to recommendations by U.S. EPA
(1995c). Equations to calculate the interception fraction of the edible portion of plant tissue
(Rpi) and the plant surface loss coefficient (kp) are presented in Tables 18 and 19,
respectively. Values of the length of a plant's exposure to deposition per harvest (TpJ and
the yield or standing crop biomass (Ypj) are obtained from the PA Agricultural Statistics
Service (PASS 1994) and the Census of Agriculture (USDC 1993a, 1993b, 1993c),
respectively. This route of exposure for plants is not considered for aboveground protected
vegetables and root vegetables.
Plant concentrations attributable to air-to-plant transfer are dependent on the vapor-
phase air concentration and an air-to-plant biotransfer factor, as can be seen in Table 20.
This type of transfer applies only to aboveground leafy and exposed plants (i.e., does not
include root or aboveground protected vegetables). The site-specific parameters are
presented in Table 20. These factors are related to various physical and chemical properties
of the chemicals. Table 21 presents equations used to estimate the air-to-plant biotransfer
factor (BVj). The vapor-phase concentration due to direct emissions (Cy) is obtained from
the air dispersion modeling. VG^ is a correction factor similar to VG^ that is introduced to
reflect the difference between the concentration in the outer few millimeters and the average
concentration in the whole vegetable. Based on U.S. EPA's (1994a) recommendations, VG^
should be set equal to 0.01 for unspecified aboveground fruits and vegetables, 1.0 for leafy
vegetables and forage, 0.5 for silage, and 0 for grain. These recommendations are based, in
part, on the reduction of chemical concentrations in unspecified fruits and vegetables as a
result of cleaning and peeling; the direct analogy of leafy vegetables and forage to azalea
leaves, the experimental leaves on which the equation was based; the assumption that silage
can be considered part leafy and part protected; and the assumption that grain is fully
protected.

3. Estimation of Chemical Concentrations in Meat, Eggs, and Milk
Stack gas chemicals in soil and plants may accumulate in animals that ingest these
media while grazing. The chemical concentration in animals is required to estimate human
exposure to chemicals via consumption of meat products, eggs, and milk from livestock that
have grazed on soils containing chemicals emitted from the stack. U.S. EPA (1993; 1994a)
presents a food chain model to estimate concentrations of stack gas chemicals in beef, milk,
pork, poultry, eggs, and deer meat. This model considers the chemical concentration in
plants and soil, the quantity of plants and soil that animals consume, and the biotransfer (Ba)
or bioconcentration (BCF) factor for each type of animal tissue. Uptake of chemicals via
inhalation and ingestion of contaminated water is assumed to be insignificant and not
considered in this assessment (U.S. EPA 1994a).
Table 23 presents the algorithm used to estimate chemical concentrations in animal
tissues. This equation includes uptake from ingestion of plants and soil as well as a
biotransfer or bioconcentration factor. Estimation of the chemical concentration in plants
was described previously. Information in Table 24 provides additional input parameters of
the type and amount of plants and soil consumed by various animals.
Table 25 presents regression equations for non-dioxin-like organic chemicals that relate
biotransfer factors to a chemical-specific octanol/water partition coefficient (K^). It should
be noted, however, that the regression equations for beef and milk, which were developed by
Travis and Arms (1988), may contain residual error (personal communication, McKone
1995) and a recent study suggests that the biotransfer factor may be independent of K^, over
a broad range (McLachlan 1994).
Considerable scientific evidence exists to indicate that bis(2-ethylhexyl)phthalate is
readily metabolized and excreted, so that very little tissue accumulation occurs in mammalian
species (Bceda 1980; Daniel and Bratt 1974;.Astill 1989). In rats, there is very little tissue
accumulation following repeated dietary treatment with 14C-BEHP. Significant uptake was
found only in liver and fat, and tissue half-lives for BEHP and its metabolites were estimated
to be 3 to 5 days for fat and 1 to 2 days for other tissues (Daniel and Bratt 1974). In
cynomolgus monkeys, the rate of excretion of label was 50 to 80 percent in the first 24
hours. The average 24-hour excretion of label was lower in dogs (67 percent) and miniature
pigs (37 percent) (Astill 1989). A comparative study of BEHP absorption and excretion in
rats, dogs, and pigs showed that the rate of clearance was rapid in all these species. Less
than 3 percent of the administered dose was found to remain in the body tissues after 96
hours , with most remaining in the intestines, and less thanl percent retained in muscle and
fat(Dceda 1980).

-------
Metabolism of BEHP has been verified in several species including man (Schmid and
Schlatter 1985). These studies collectively indicate that there is veiy low potential for
significant bioaccumulation of BEEIP in the human food chain (ATSDR 1993a). Based on
the work of Dceda et al. (1980), a conservative "metabolism factor" (MF) of 0.01 (to
represent an upper limit of 1 percent remaining in fat and muscle) was used to modify the
biotransfer factor derived from Travis and Arms (1988) (see Table 23). Metabolism factors
for all other compounds were conservatively assumed to be 1.0.
Egg concentrations are assumed to be related to K^ by a regression equation developed
by California EPA for their CalTOX exposure model (CalEPA 1993). The uncertainties
associated with the use of these equations are discussed more fully in the uncertainty section
of the Human Health Risk Assessment. These regression equations are all based on
experimental data that relate the chemical concentration in feed to the chemical concentration
in animal tissue (fresh weight). For dioxin-like compounds (i.e., conservatively includes
chlorinated biphenyl compounds in addition to dioxin and furan compounds) in beef, milk,
pork, chicken, egg, and deer meat, however, an empirical BCF is used that relates the
concentration of the ingested feed to the concentration in animal fat. This BCF is congener-
specific but is based on a study with one animal (U.S. EPA 1994a). The uncertainty section
of the Human Health Risk Assessment discusses this uncertainty more fully. The
concentration in animal fat is converted to fresh weight by multiplying by the fat fraction, as
shown hi Table 23. For metals, biotransfer factors reported in the literature are used to
estimate concentrations in animal tissue (fresh weight). Specifically, biotransfer factors for
cadmium, mercury, selenium, and zinc are presented in U.S. EPA (1995c). For the other
metals, the source of the biotransfer factor is found in Table 3.
To account for the fraction of the vegetation ingested by the animal that is grown near
the farm site and thus could be impacted by incinerator emissions, an F; factor is introduced.
A value for F; is assigned based on local data on the fraction of grain, silage, etc. that is
imported into the area. Consumption of forage by the various livestock is assumed to have
an F; of 1.0. Consumption of grain and silage by the various livestock also has an F; of 1.0
except for dairy cattle ingestion of grain and silage, which has an Fj of 0.9. These site-
specific values were estimated based on a discussion with a local agricultural extension agent
(personal communication, Miller 1993).
To correct for the differences in transfer efficiency of soil as compared to feed, a B,
factor is added to the equation in Table 23. Because the BCF was developed based on
vegetative intake, it must be reduced to account for the fact that soil is a less efficient vehicle
of transfer as compared to feed. A Bs of 0.65, therefore, is used as suggested by U.S. EPA
(1994a).

It should be noted that feed lot fattening of beef cattle is not considered in this
assessment because discussion with local agricultural agents indicated that no feed lots are
present in this area. If for some reason, however, beef cattle are fattened prior to slaughter
(e.g., a farmer has a special diet for his cattle or beef cattle are sent to feed lots outside the
area and return to the area as beef), the concentration in beef could be overestimated by
about a factor of two. This overestimation does not apply for the subsistence farmer
scenario, however, because it is reasonable to assume that feed lot fattening does not occur
(U.S, EPA 1994a).
Chicken and egg concentrations may be similarly overestimated if chickens are raised in
cages because the equations to estimate chicken concentrations are based on free-ranging
chickens. Caged chickens would not have access to contaminated soil like free-ranging
chickens, so their soil intake would be reduced. However, because soil intake is assumed to
make up only 3% of a chicken's total intake, this overestimation is likely to be small.

4. Estimation of Surface Water Concentration
Surface water bodies may receive stack gas chemicals from direct deposition, from
runoff of contaminated soils in the vicinity of the WT1 facility, and from eroded soils. The
chemical concentration in surface water is required to estimate human exposure through
surface water ingestion and dermal contact, and to estimate the uptake of chemicals from the
surface water by fish. U.S. EPA (1994a) presents a model to estimate chemical
concentrations in surface water bodies, shown in Tables 26 to 33. This model, and not other
models suggested by U.S. EPA (e.g., U.S. EPA 1990a; 1993) is used because it was
developed specifically for dioxin-like compounds, the class of chemicals that present the
greatest health effects in this assessment. Additionally, this model contains fewer uncertain
parameters than the other models. The assumptions contained in this algorithm include the
following:
• The impact to the water body is correlated to concentrations on watershed soils
and particles that deposit on the water body,
• Soil concentrations within a watershed and impacts to the water body are uniform,
• Sorption of compounds onto surface soil, suspended solids, and bottom sediments
is principally a function of the contaminant's organic carbon partition coefficient
(KoJ and the organic carbon content of soils and sediment,
• Chemicals enter into a surface water body via soil erosion, surface runoff, and
direct deposition,
• The concentration of contaminants on eroding soil is "enriched" due to the
preferential erosion of lighter and higher organic matter material and the
preferential binding of contaminants to these lighter and higher organic matter
material,
• The concentration of contaminants sorbed to suspended matter is "enriched"
compared to bottom sediments for similar reasons, that is, contaminants will
preferentially bind to particles that remain in suspension because they tend to be
lighter and have higher organic matter material as compared to particles that settle
to the bottom,
• Steady state is achieved between the concentration in the dissolved phase in the
water column, the concentration in the suspended sediment, and the concentration
in bottom sediments,
• A mass balance is maintained between the soil reaching the water body via erosion
and direct deposition, the suspended sediment, and the bottom sediment, and
Volume V External Review Draft
Appendix V-7 41 Do Not Cite or Quote
-------
• Volatilization out of and degradation in the water body are not modeled, nor is
resuspension of bottom sediment.
To determine surface water concentrations, the concentration on the suspended sediment
must be estimated. The suspended sediment concentration is calculated with the total load of
chemical to the water body (p) and the annual amount of suspended sediment (<£), as
presented in Table 28. The values for p and ^ are determined by the equations in Tables 29
to 33.
Once the suspended sediment concentration is determined, the dissolved concentration is
estimated by calculating a mass balance between the mass of contaminants entering the water
body and the amount that partitions to the three compartments in the water body, a) dissolved
in the water column, b) sorbed to suspended material, and c) sorbed to particles settling to
the bottom. Specifically, the dissolved concentration is estimated by assuming that
equilibrium is maintained between the sorbed and dissolved phases (Table 26). The bottom
sediment concentration is determined by the relationship with the concentration on the
suspended sediment shown in Table 27. This relationship assumes that suspended sediment
concentrations are enriched in comparison to bottom sediment concentrations, according to
the organic carbon content.

5. Estimation of Chemical Concentrations in Fish
Stack emissions may enter local surface water bodies through both direct deposition and
deposition onto watershed soils followed by runoff and erosion into the surface water bodies.
Once in the water body, these stack gas chemicals may be incorporated into fish. The
chemical concentration in fish is required to estimate human exposure to chemicals via
ingestion of fish. U.S. EPA (1990a) presents a model to estimate chemical concentrations in
fish. This model, which calculates chemical concentrations by considering the water
concentration and a bioconcentration factor (BCF), is generally appropriate for chemicals
with high water solubility and low affinity for sediments. This equation relates the
concentration of chemicals in the fish to the dissolved concentration in water but does not
consider uptake from other sources such as diet. The equation was modified, therefore, to
include a bioaccumulation factor (BAF) instead of a BCF. Bioaccumulation refers to uptake
of a chemical from all sources such as diet and bottom sediments as well as the ambient
water. This equation is presented in Table 34. Estimation of water concentrations were
described previously. BAFs are calculated as the product of a BCF and a food-chain
multiplier (FCM) (U.S. EPA 1995b). U.S. EPA (1995b) presents FCMs for various trophic
levels based on log Kow. The FCMs for the piscivorous fish trophic level 4 are used in this
assessment. BCF values for specific substances of concern are compiled from the scientific
literature and other sources, e.g., the U.S. EPA AQUIRE data base.
It should be noted that the BCF for mercury differs depending on its form (e.g., methyl
mercury or inorganic mercury) in the water column, with methyl mercury incorporated by
fish nearly ten times as much as inorganic mercury. The rate of methylation in the water
column is affected by microbial action and abiotic processes and generally results in no more
than 25 % of the total mercury in a water column existing as a methyl mercury complex. In
reality, less than 10% is typically observed (U.S. EPA 1994d). This assessment, however,
conservatively assumes that 25 % of the total mercury in the water column exists as a methy
mercury complex. Additionally, it should be noted that the accumulation of PAHs in fish is
conservatively evaluated in this assessment. Despite their high lipid solubility, these
compounds are readily metabolized (ATSDR 1993b, Eisler 1987), so significant
bioaccumulation is not expected. This conclusion is further substantiated by West et al.
(1984) who observed that higher molecular weight PAHs, which include the largest class of
chemical carcinogens and those selected as surrogate organic chemicals in this assessment, do
not appear to accumulate in fish. However, for the purposes of this assessment, PAHs are
assumed to not metabolize in fish, and they are evaluated in the same manner as the other
chemicals.

Because dioxin-like compounds have a low water solubility and high affinity to
sediments, U.S. EPA (1994a) suggests an alternative equation, which is also provided in
Table 34. Estimation of bottom sediment concentrations (C^ was described previously.
The biota to sediment accumulation factor (BSAF) is a congener-specific value that relates
the chemical concentration in the organic carbon of the bottom sediment to the concentration
in the lipid of the fish. It is an empirical value derived from the literature. The lipid
concentration is converted to a whole fish concentration by multiplying by the fraction lipid
content of fish (f^,,), assumed to be 0.07 (U.S. EPA 1994a).

6. Estimation of Chemicals in Mothers' Milk
Constituents in breast milk provide an exposure pathway to infants, a potentially
sensitive population sub-group. Travis et al. (1988) presents a generic methodology to
estimate breast milk concentrations of organic compounds. This methodology is summarized
in Table 35. The mothers' total daily intake is summarized in Table 36. Biotransfer factors
are a function of the octanol/water partition coefficient (K^J and can be calculated by the
modified Travis et al. (1988) equation shown in Table 37. As noted in Section 3 of this
appendix, a metabolism factor, MF, is applied to account for the metabolism of bis(2-
ethylhexyl)phthalate in mammals. Based on studies on the metabolism of bis(2-
ethylhexyl)phthalate in the human food chain (Ikeda et al. 1980; Daniel and Bratt 1974), a
metabolism factor of 0.01 is applied for this compound. For all other compounds, the value
of MF is 1.0 (i.e., no metabolism is assumed to occur). Inorganic compounds, including
metals, are not generally lipophilic and thus accumulation in mother's milk is not anticipated.
Smith (1987) developed an alternative approach to estimating concentrations in breast
milk for dioxin-like compounds. This approach is based on the half-life of dioxins within the
human body, estimated as five to seven years (U.S. EPA 1994a), and can be seen in
Table 35.
The lifetime average maternal intake relevant to the infant's exposure is the mother's
average daily dose during her lifetime, rather than the dose during the period of exposure.
The LT over ED factor is added to correct for the lifetime averaging of maternal intake (i.e.,
to estimate an average daily dose during the period of exposure) as represented in Table 36.

APPENDIX V-8
Estimation of Exposure Factors
Volume V External Review Draft
Appendix V-8 Do Not Cite or Quote
-------
A. Introduction
This appendix identifies the typical and high-end exposure factor values that are used
in estimating dose in the risk assessment (Chapter VII) and conducting the sensitivity analysis
(Chapter VDI) for the WTI hazardous waste incinerator. In this appendix, typical refers to
values that represent the mean or median of the distribution of possible values. As noted in
the Exposure Assessment Guidelines (U.S. EPA 1992a), for skewed or truncated
distributions, the median may be more representative of the central tendency value than the
mean. Most exposure factor distributions are skewed or truncated; therefore, when possible,
the median value is used. The term "high end" refers to the values toward the upper end of
the distribution, generally 90th percentile and greater.
As discussed in Volume n, the key assumptions that are used in performing the risk
assessment have been identified. Table 34 at the end. of this appendix summarizes the key
assumptions that are used in developing exposure factors. The table of key assumptions
indicates the basis for the assumptions listed, the estimated relative magnitude of effect each
assumption is estimated to have on the overall risk assessment, and the direction of the.
effect, if known. It is not anticipated that any of the assumptions made in estimating
exposure factors would have a significant (high1) effect on overall results.
B. Exposure Factors
This appendix summarizes the values and the sources of these values for exposure
factors specific to the exposure pathways. A number of exposure factors, however, are not
expected to change between exposure pathways, such as exposure duration, body weight, and
averaging time. Exposure duration is based on the estimated length of time that an individual
resides at one location. For adult residential exposure, U.S. EPA (1990a) recommends
typical (50th percentile) and high-end (90th percentile) values of 9 and 30 years,
respectively, based on U.S. census data. For both the typical and high-end exposure
duration estimates for children, exposure duration is assumed to be six years (corresponding
to the assumed age range of the child, 1 to 6 years). The subgroup of school-age children is
assumed to have an exposure duration of six years for both the typical and high-end exposure
duration estimates, corresponding to the typical period of school for an elementary school
child. For the exposed fanning subgroup, U.S. EPA (1990a) recommends "typical" and
"worst case" exposure durations of 20 and 40 years, respectively. These values are used as
1 A "high" effect is estimated to be equal to a potential over- or underestimate of total
risks by a factor of ten or more.

typical and high-end exposure durations, respectively, for adult fanners and subsistence
fanners. These exposure durations are presented in the tables of exposure factor values
provided later in this appendix.
Body weight is a second exposure factor that is specific to each exposure group but
does not change from one exposure pathway to another. The adult exposure subgroups (i.e.,
resident, fanner, and subsistence fanner) are assumed to have a body weight of 70 kilograms
(typical and high-end). The child resident exposure subgroup is assumed to be pre-school
age children (i.e., 1 to 6 years-old). Based on U.S. EPA (1990a) guidance, the average
body weight for a child in this age range is approximately 15 kg (average of male and female
children). For the school-age children, who are assumed to be in the age range of 7 to 12
years, a body weight of 31 kg is assumed, based on data presented by U.S. EPA (1990a).
In an exposure assessment, it is generally necessary to provide two different estimates
of the exposure dose (for each pathway), one for substances with noncancer effects, which is
referred to as the average daily dose (ADD), and a second for substances with carcinogenic
effects, referred to as the lifetime average daily dose (LADD). The ADD is the dose that an
individual is likely to receive on any day during the period of exposure. In cases where the
exposure is intermittent, it is generally appropriate to average the dose over the period of
exposure; therefore, the averaging time is equal to the exposure duration in units of days
(ED in years x 365 days/year). For carcinogens, the LADD is estimated by averaging the
total cumulative dose received by an individual over a lifetime, which is estimated by U.S.
EPA (1989) to be 70 years (25,550 days).
All other remaining exposure factors vary based on the exposure group and the route
of exposure. The values used to determine doses for each of the routes of exposure are
discussed below for the remaining factors.
1. Inhalation of Ambient Air
Direct exposure to chemicals released from the WTI facility stack may occur
to individuals living in the vicinity of the facility. The following factors must be
considered when estimating exposure via this pathway: 1) the concentration of
chemical in the air; 2) the inhalation rate; and 3) the frequency and duration of
exposure. Values of the exposure factors for this pathway are presented in Tables 1
and 2.
U.S. EPA (1990a) recommends an adult inhalation rate of 20 mVday (0.833
nrVhr). This value is used for the typical and high-end inhalation rate for all adult
subgroups. For school-age children, an inhalation rate of 20 nrVday (0.833 mVhr) is
also used for the typical and high-end values based on age-specific inhalation rates
compiled by U.S. EPA (1990a). For children in all other subgroups (not including

Appendix V-8 2 Do Not Cite or Quote
-------
school-age children), a value of 16 nrVday (0.667 nrVhr) is estimated, based on age-
specific inhalation rate data presented by U.S. EPA (1990a). This value is used for
both the typical and high-end values.
2. Soil Ingestion
Exposure to chemicals in soil is assumed to occur through incidental ingestion
of soil by adult and child residents, fanners (including subsistence farmers), and
school-age children. The following factors must be considered when estimating
exposure via this pathway: 1) the chemical concentration in soil; 2) the rate of soil
ingestion; and 3) the period of time over which ingestion occurs. The exposure
factors for this pathway are provided in Tables 3 and 4. The values used for the
period of exposure, body weight, and averaging time were discussed earlier. The
remaining factors are the soil ingestion rate, and the exposure frequency.
a. Soil Ingestion Rate
The soil ingestion rates used in the WTT Risk Assessment are based on
various sources of U.S. EPA guidance. Very limited data are available to
estimate the incidental ingestion of soil by adults. A value of 25 mg/day for
an "average adult" is cited by U.S. EPA (1990b), based on work performed by
LaGoy (1987). This value is used for the typical soil ingestion rate for adult
residents. U.S. EPA (1991) recommends a value of 100 mg/day for
individuals older than six years of age as an "upper bound" value. This value
is used as the high-end estimate of soil ingestion for adult residents.
For children under six years, U.S. EPA (1990b) recommends a high-
end value of between 100 and 200 mg/day for ingestion of soil. The lower
and upper ends of this range are used as the typical and high-end ingestion
rates for children, respectively.
The soil ingestion rate for school-age children is based on soil ingestion
data presented by U.S. EPA (1990a). Soil ingestion rates divided between
indoor (3 mg/day) and outdoor (50 mg/day) are presented by U.S. EPA
(1990a), based on a study by Hawley (1985). These values are prorated based
on the assumption that indoor exposure would occur year round (365
days/year) and outdoor exposure would only occur during wanner months
(estimated to be 200 days/year, based on the number of days that the
maximum daily temperature exceeds 50 F°). The resulting typical ingestion
rate for school-age children is estimated to be 30 mg/day.
Volume V External Review Draft
Appendix V-8 3 Do Not Cite or Quote
-------
For the high-end ingestion rate for school-age children, the same
method is used, but it is assumed that the outdoor soil ingestion rate is 100
mg/day (for 200 days/year). The indoor soil ingestion rate is still assumed to
be 3 mg/day. The resulting prorated high-end soil ingestion rate is estimated
to be approximately 60 mg/day.
The soil ingestion rates for farmers are based on U.S. EPA (1991)
guidance for outdoor workers and residential ingestion rates. It is assumed
that fanners would ingest significantly greater amounts of soil during periods
of outdoor field work. For the high-end ingestion rate, a value of 480
mg/day, recommended by U.S. EPA (1991) for outdoor workers, is applied to
fanners working in the field. The typical soil ingestion rate for farmers
working in the field is assumed to be 100 mg/day, an upper-bound estimate for
typical residential exposure (U.S. EPA 1991). During non-field activities, it is
assumed that farmers would have the same soil ingestion rates as adult
residents, 25 mg/day and 100 mg/day for the typical and high-end values,
respectively.
b. Exposure Frequency
An exposure frequency for soil ingestion of 350 days/year
recommended by U.S. EPA (1991) is used for the typical and high-end
estimate for all exposure subgroups. This assumes that incidental soil
ingestion occurs both indoors and outside.
For the fanner, the exposure frequency is divided between outdoor
field work and non-field work. Site-specific data are not available; therefore,
a reasonable period of exposure is estimated. It is assumed that exposure
frequency is divided equally between field and non-field activities.
3. Dermal Contact with Soil
Dermal exposure to chemicals in soil in the vicinity of the facility may occur
when residents (children and adults), school-age children, and fanners come into
contact with soils. The following factors must be taken into account when evaluating
this potential route of exposure: 1) the chemical concentration in soil; 2) the skin
surface area exposed to the soil; 3) the amount of soil deposited on the skin; 4) the
frequency and duration of exposure; and 5) the extent to which chemicals adsorbed to
the soil are subsequently absorbed through the skin. The exposure factors for this
pathway are presented in Tables 5 and 6. Those not discussed previously are
presented below.
Volume V External Review Draft
Appendix V-8 4 Do Not Cite or Quote
-------
a. Skin Area Exposed
The amount of skin available for exposure to soil is estimated based on
the expected activities and types of clothing worn during the exposure period.
For the typical value of skin area exposed, it is assumed for all exposure
subgroups that on average, exposure would primarily occur to hands and
forearms. Age-specific-skin surface areas of these body parts derived from
U.S. EPA (1990a) guidance are summed to estimate the typical values.
For the high-end value, it is assumed that the area of exposure is the
hands, forearms, and half the head and legs. Age-specific skin surface area
values compiled by U.S. EPA (1990a) for these body parts are added to
estimate high-end values.
b. Soil to Skin Adherence Factor
The amount of soil that adheres to the skin affects the amount of
chemical that is available for absorption through the skin. U.S. EPA (1992b)
recommends a typical value of 0.2 mg/cm2 and a high-end value of 1.0
mg/cm2.
c. Absorption Factor
Limited data are available to estimate chemical-specific absorption
factors for the constituents being considered in the risk assessment. For
2,3,7,8-TCDD, U.S. EPA (1992b) recommends a range of 0.001 to 0.03 (0.1
to 3 percent) for the dermal absorption fraction. Data for other dioxin-like
compounds are not available; therefore, the upper end of this range, 0.03, is
used as the dermal absorption fraction for all dioxins, furans, and dioxin-like
compounds considered in the risk assessment. For other organic compounds,
a value of 0.06 (6 percent) is used, based on the upper end of the range of
values (0.006 to 0.06) estimated by U.S. EPA (1992b) for trichlorobenzene.
Similarly, for metals, a value of 0.01 (1 percent) is used, based on the range
of absorption fractions (0.001 to 0.01) estimated by U.S. EPA (1992b) for
cadmium.
d. Exposure Frequency
It is assumed that dermal contact with soil would occur at the same
frequency as soil ingestion. Therefore, the exposure frequencies for dermal
contact with soil for all subgroups are assumed to be the same as the exposure
frequencies for soil ingestion.
Volume V External Review Draft
Appendix V-8 5 Do Not Cite or Quote
-------
As noted earlier, the period of exposure for fanners is divided between
outdoor field work and non-field activities for fanners. It is assumed that
exposure frequency is divided equally between field and non-field activities.
4. .Consumption of Meat and Eggs from Locally Raised Livestock
Exposure to contaminated meat and eggs may occur when residents and local
fanners consume meat (beef, pork, and poultry) from livestock raised in the vicinity
of the facility. The extent of exposure to chemicals through this pathway is
dependent on: 1) the chemical concentration in the meat or eggs; 2) the meat or egg
ingestion rate; 3) the fraction of meat or eggs ingested that comes from a local
source; and 4) the frequency and duration of exposure. Exposure factors used in this
pathway are presented in Table 7 and 8 and are discussed below.
a. Consumption Rate
Age-specific consumption rates for meats (including beef, pork, and
poultry) and eggs are estimated based on a 1987-88 national food consumption
survey performed by the U.S. Department of Agriculture (USDA 1993a). For
children, median food consumption rates are estimated based on a weighted
average of food consumption rates for 1 to 2-year-old and 3 to 5-year-old
children (based on the percentage of the survey population in each group).
Food consumption rates for school-age children are based on weighted
averages for 6 to 11-year-old girls and 6 to 11-year-old boys. Adult food
consumption rates are based on the weighted average of adult (older than 20
years) males and females.
USDA (1993a) reports consumption data in several categories of meat
products (e.g., lunch meats, sausages, etc.); therefore, consumption rates of
specific meats (e.g., beef, pork, chicken) were developed from a combination
of data for several food types. Specifically, age-specific meat consumption
data are presented by USDA (1993a) in several categories including: (1) beef,
(2) pork, (3) lamb/veal/game, (4) organ meats, (5) frankfurters/sausages/lunch
meats, (6) chicken, (7) other poultry, (8) fish/shellfish, and (9) meat mixtures.
Consumption rates of lamb/veal/game (3 listed above) and organ meats (4) are
relatively insignificant and are not considered further hi this analysis. Meat
consumption included in the frankfurters/sausages/lunch meat category (5) is
proportionally divided between the beef (1), pork (2), chicken (6), and other
poultry categories (7), based on the consumption rate data for these individual
meat types reported by USDA (1993a). Similarly, the meat mixtures category
Volume V External Review Draft
Appendix V-8 6 Do Not Cite or Quote
-------
(9) is divided proportionally between the beef (1), pork (2), chicken (6), other
poultry (7), and fish/shellfish (8) categories. The resulting meat consumption
estimates aie summarized in Table 9.
High-end meat consumption rates are not available from the USDA
(1993a) data. Therefore, high-end consumption rates are estimated by the
product of median consumption rates presented in Table 9 and the ratio of 90th
percentile to median of individual food consumption rates estimated from
consumption rate distributions developed by Pao et al. (USDA 1982). The
90th percentile to median ratios for the foods in Table 9 are presented in Table
10. Estimated high-end meat consumption rates are presented in Table 9.
b. Exposure Frequency
The USDA consumption data are based on daily consumption;
therefore, the exposure frequency is assumed to be 350 days per year as
recommended by U.S. EPA (1991).
c. Fraction Ingested from Contaminated Source
Although no data are available that directly measure the fraction of
meat consumption in the area of the WTI facility that is derived from locally
raised livestock, statistics concerning the raising, marketing, and slaughter of
livestock in the region surrounding the WTI facility are available. The
following description provides a summary of the cattle-raising data that are
available and the methodology used to estimate the fraction of beef consumed
that is from locally raised cattle. A similar process is used for the other types
of meat commodities.
The primary source of information on beef farming statistics is
agricultural data compiled by the Agricultural Statistics Service associated with
the Departments of Agriculture in each of the three states (Ohio, Pennsylvania,
West Virginia) located in the vicinity of WTI (ODA 1994; PDA 1994; WVDA
1994). Summaries of livestock data are published annually and include such
parameters as the total number of cattle/calves in the state and the number of
calves born annually. Table 11 summarizes state-wide beef fanning statistics
for Ohio, Pennsylvania, and West Virginia. The value for total cattle/calves in
Table 11 is the number of cattle related to beef and dairy farming that were
reported in the state as of January 1, 1993. In addition, the number of calves
born hi each state annually is provided in Table 11.
Volume V External Review Draft
Appendix V-8 7 Do Not Cite or Quote
-------
Information on the disposition of beef cattle and calves is also provided
in the Agricultural Statistics Service summaries. The number of cattle and
calves that are slaughtered in registered slaughtering facilities in each state is
shown in Table 11. The source of the slaughtered animals, however, is not
available because processing facilities are not required to keep records on the
origin/owner of the cattle sold for slaughter. A report on the state of the
slaughtering industry in Ohio (Distad 1992) indicates that Ohio does not have
any "large" capacity cattle slaughtering facilities, but does have many smaller
operations with slaughtering capacities of less than 1,000 head per year.
Furthermore, the report indicates that Ohio is a net exporter of beef for
slaughter. Based on slaughter data published by the West Virginia Department
of Agriculture (1994), the same situation would appear to hold true for West
Virginia.
Pennsylvania, on the other hand, is home to two of the largest cattle
slaughtering facilities in the country (10th and 12th largest overall) with a total
annual slaughtering capacity of approximately 740,000 head (Distad 1992), of
which a large fraction are likely to be imported from out of state. Because of
these two very large plants (both of which are located in the eastern part of the
state), Pennsylvania is a net importer of beef cattle for slaughter. For the
present analysis, it is necessary to estimate the number of cattle that are raised
in Pennsylvania and are slaughtered in Pennsylvania. Including the data from
these plants would significantly overestimate this value. To obtain an estimate
of Pennsylvania-bred cattle slaughtered in the state, therefore, the 740,000
head slaughtered at the large slaughtering houses in eastern Pennsylvania are
subtracted from the state total slaughter. The resulting estimate, 229,000
head, is more consistent with the other states in the area and with the 220,000
beef steers raised in the state (PDA 1994). This value, therefore, is used to
estimate the number of Pennsylvania-bred cattle slaughtered in the state.
County-specific beef farming data available from the Agricultural
Statistics Service data summaries are limited. It is necessary, therefore, to
estimate a number of parameters based on state-wide data. Published data
(ODA 1994; PDA 1994; WVDA 1994) on the total cattle herd in each of the
three counties (Columbiana, Ohio; Beaver, Pennsylvania; and Hancock, West
Virginia) that are included in the risk assessment study area are provided in
Table 12. In addition, the calf crop in each of these three counties, and the
cattle and calf slaughter are estimated based on the fraction of the state herd in
each county and the state-wide statistics in Table 12.

-------
This methodology assumes that beef raising and slaughter practices are
similar across all parts of a state, which may not necessarily be true. To
address this uncertainty, agricultural extension agents for the counties located
in the vicinity of the WTI facility were interviewed regarding local beef cattle
raising practices. Although no actual data were obtained from these sources,
judgments concerning local fanning practices proved to be a valuable resource
to supplement the state-wide data.
For example, the primary type of beef fanning performed in the eastern
Ohio/western Pennsylvania area involves cow/calf operations that raise cows to
produce calves. These calves are raised locally for 6 to 9 months, weaned,
and generally sold to feedlots out of state (personal communication, county
agricultural extension agents, August 1994). In other portions of these states
(Ohio, Pennsylvania, West Virginia), this practice may not be as
commonplace.
The state-wide statistics, therefore, may not accurately represent local
beef farming practices. For example, according to the state-wide data (ODA
1994; PDA 1994; WVDA 1994), the fraction of calves born that are marketed
ranges from 0.23 for Ohio to 0.51 for West Virginia. Discussions with local
agricultural extension agents indicate, however, that 60 to 70 percent of a local
calf crop in any given year is marketed (sold at auction to feedlots in western
Ohio or the western U.S.) and may range as high as 80 to 90 percent of the
local calf crop, but is rarely below 50 percent. It is likely, therefore, that
estimates of local slaughter provided in Table 12 overestimate actual local
slaughter in these counties.
Based on the limited data available, the following methodology is used
to estimate the availability of locally raised beef in the vicinity of the WTI
facility:
• Beef slaughter in counties included within the study area is estimated
based on state-wide cattle slaughter data, as presented in Table 13.
• It is assumed that beef cattle slaughtered within the three-county area is
consumed within the same area.
• The amount of beef derived from each head of slaughtered cattle is
estimated to be 50 percent of the average live weight of cattle
slaughtered in the state (1,100 pounds for Ohio, 1,200 pounds for
Volume V External Review Draft
Appendix V-8 9 Do Not Cite or Quote
-------
Pennsylvania, and 1,000 pounds for West Virginia per: ODA 1994;
PDA 1994; WVDA 1994).
• The amount of beef derived from calf slaughter is estimated similarly
based on average live weights for calves of 500 pounds in Ohio and
400 pounds in Pennsylvania (ODA 1994; PDA 1994). West Virginia
calves are assumed to have an average live weight of 450 pounds.
Table 13 provides an estimate of locally raised beef available for
consumption within each county in study area. Based on age-specific
population within the three-county area (CACI1992), presented in Table 14.
and age-specific beef consumption rates (Table 9), the total annual beef
consumption in the three-county area is 19.8 million pounds. Therefore,
locally raised beef accounts for approximately 15 percent. It is likely that this
methodology overestimates the fraction of beef consumed that is raised locally,
based On the type of beef raising performed in the area surrounding WTT.
For other types of meat products (i.e., pork, chicken, turkey) and eggs,
a similar analysis of available livestock-raising statistics was conducted. For
pork, the number of hogs slaughtered in each of the three counties is estimated
based on the product of the fraction of the total state hog herd in each county
and the total state hog slaughter. Assuming one-half of a hogs live-weight is
used for consumption, the total pork available for consumption is estimated as
1.53 million pounds, as shown in Table 15. Based on the age-specific
population within the three-county area (14) and age-specific pork consumption
rates (Table 9), the total annual pork consumption in the three-county area is
8.63 million pounds. Therefore, pork from locally raised livestock accounts
for approximately 15 percent of the pork diet for residents in the vicinity of
WTL
For chickens, agricultural census data (USDC 1993a,b,c) indicate that
very few chicken farms (for meat) are located in the three counties located
within the study area. According to the agricultural census data, the total
number of broilers within the three-county area was less than 400 birds in
1992. It is estimated, therefore, that locally raised chicken would comprise an
insignificant portion of a typical resident's diet. A similar conclusion was
developed for turkey.
The fraction of egg diet for residents that is derived from locally raised
chickens is estimated based on the number of eggs produced locally and the
Volume V External Review Draft
Appendix V-8 10 Do Not Cite or Quote
-------
local population. Table 15 summarizes the egg data for the three counties
surrounding the WTI facility and presents the estimated amount of eggs from
locally raised chickens. Total egg consumption in the three-county area
surrounding the WTI facility is approximately 20.6 million pounds. Based on
the age-specific population (Table 14) and age-specific egg consumption rates
(Table 9), the total annual egg consumption in the three-county area
surrounding the WTI facility is approximately 5.5 million pounds. Therefore,
locally raised eggs account for approximately 16.percent of the egg diet .for
local residents.
The high-end values for the fraction of meat (or eggs) consumed by
residents that is from locally raised livestock are estimated to be two times the
average values.
For farm families, limited data are available to estimate the fraction of
meat and eggs that are derived from locally raised livestock. The fraction of
meat and eggs consumed that is local is estimated based on information
provided by U.S. EPA (1990a) for consumption of beef by farm families. The
estimated central tendency and high-end values, therefore, are estimated to be
0.44 and 0.75, respectively, as indicated in Table 7 and 8.
It is also assumed that a subgroup of farmers may exist that derive all
their meat from their own farm (subsistence farmers). A value of 1 (i.e., 100
percent) is applied for this exposure subgroup of subsistence fanners.
5. Consumption of Milk and Milk Products from Locally Raised Cows
Exposure to contaminated milk and milk products may occur when residents
and local farmers consume milk and milk products from cows that have been raised in
the vicinity of the facility. The extent of exposure to chemicals through this pathway
is dependent on: 1) the chemical concentration in the milk and milk products; 2) the
consumption rate of milk and milk products; 3) the fraction of milk and milk products
ingested that comes from a local source; and 4) the frequency and duration of
exposure. Exposure factors used in this pathway are presented in Tables 16 and 17
and are discussed in the following sections.
a. Milk and Milk Products Consumption Rate
Age-specific consumption rates for milk and milk products are
estimated based on a 1987-88 national food consumption survey performed by
the U.S. Department of Agriculture (USDA 1993a). For children, median
food consumption rates are estimated based on a weighted average of
Volume V External Review Draft
Appendix V-8 11 Do Not Cite or Quote
-------
consumption rates for 1 to 2-year-old and 3 to 5-year-old children (based on
the percentage of the survey population in each group). Consumption rates for
school-age children are based on weighted averages for 6 to 11-year-old girls
and 6 to 11-year-old boys. Adult consumption rates are based on the weighted
average of adult (older than 20 years) males and females.
USDA (1993a) reports milk and dairy products consumption data in
several categories including: (1) total milk products, (2) milk and milk drinks
(subdivided into (2a) fluid milk and (2b) yogurt), (3) milk desserts, and (4)
cheese. Consumption rates for cheese (category 4), milk desserts (3), and
yogurt (2b) listed by USDA (1993a) are used and are presented in Table 18.
The consumption rate of "milk and milk drinks" listed in Table 18 is the total
milk and milk drinks (category 2) consumption rate reported by USDA (1993a)
minus the yogurt (2b) consumption rate. The cream consumption rate in Table
18 is estimated by subtracting the identified categories (i.e., milk and milk
drinks [2], milk desserts [3], and cheese [4]) from the total milk products
consumption rate reported by USDA (1993a). The resulting consumption rates
for the various age groups considered in the risk assessment are summarized in
Table 18.
It should also be noted that the butter consumption rate shown in Table
18 is based on the consumption rate for "table fats" reported by USDA
(1993a). Because the table fats category listed by USDA includes margarine
and butter substitutes, it is likely that the butter consumption rate in Table 18
is overstated; however, the butter consumption rate is relatively low and will
likely not have a significant effect on food consumption risks.
High-end milk and milk product consumption rates are estimated as
described earlier for beef. The upper end of the consumption distribution is
estimated as the product of median consumption rates presented in Table 18
and the ratio of 90th percentile to median of individual food consumption rates
estimated from consumption rate distributions developed by Pao et al. (USDA
1982). The 90th percentile to median ratios for the foods in Table 18 are
presented in Table 10. Estimated high-end milk and milk product consumption
rates are presented in Table 18.
b. Exposure Frequency
The USDA consumption data are based on daily consumption;
therefore, the exposure frequency is assumed to be 350 days per year as
recommended by U.S. EPA (1991).

c. Fraction Ingested from Contaminated Source
Table 19 summarizes the available milk cow, production, and
marketing data available from the Agricultural Statistics Services for Ohio,
Pennsylvania, and West Virginia (ODA 1994; PDA 1994; WVDA 1994).
Agricultural extension agents representing counties in the vicinity of the
WTI facility were contacted to provide a local characterization of dairy
fanning practices (personal communication, county agricultural extension
agents, August 1994). In general, the extension agents reported that dairy
fanning in the eastern Ohio/western Pennsylvania area is not significantly
different from other parts of Ohio and Pennsylvania, and that state-wide
statistics are likely applicable.* Table 20 provides estimates of county-specific
milk cow herd size and milk production statistics, and estimates of milk
marketing, based on the state-wide data for the three counties surrounding the
WTI facility. The milk marketing data include information on milk marketing
to plants/dealers and direct sales to consumers. Discussions with the
agricultural extension agents indicate that the milk marketing to plants and
dealers is divided between large processing facilities that are not generally
located in the area and smaller, local processing facilities that generally service
communities within 5 to 10 miles of the processing facility.
To estimate the distribution of milk between the large processing
facilities and the local handlers, a USDA (1988) milk marketing report that
summarizes county-by-county and state contributions to federally inspected
milk processing plants (these are the large processing facilities referred to
above) was reviewed. Federally inspected milk processing plants are assigned
to "milk marketing areas" under the Federal Milk Marketing Order. In
general, milk produced within a milk marketing area stays within the area
(USDA 1994). However, these marketing areas are generally very large. For
example, the Eastern Ohio-Western Pennsylvania milk marketing area covers
the eastern third of Ohio, the western third of Pennsylvania, and the West
Virginia panhandle, as shown in Figure 1. USDA milk marketing data for this
area were reviewed to estimate the fraction of milk produced in the area
surrounding the WTI facility that is sent to the large, federally inspected milk
processing facilities contained within the Eastern Ohio-Western Pennsylvania
milk marketing area.
Based on milk marketing data for Beaver County, Pennsylvania (USDA
1988) and milk production data for the same year (PDA 1994), it is estimated
that approximately 85 percent of the milk produced in Beaver County in
Volume V External Review Draft
Appendix V-8 13 Do Not Cite or Quote
-------
December 1988 was processed in the federally inspected plants (i.e., 15
percent remains local). No data were available for the other two counties
(Columbiana and Hancock); therefore, Beaver County data are assumed to
apply to the entire three-county area. Table 21 presents the estimated amount
of milk that is produced and remains in the three-county area surrounding the
WTI facility.
To estimate the amount of locally derived milk that is available for
consumption in the area surrounding the WTI facility, the milk that remains
local (including milk consumed on farm, milk sold directly to consumers, and
milk processed locally) was compared to the total annual consumption in the
three-county area surrounding the facility. The amount.of milk that remains
local is estimated in Table 21 as 32.3 million pounds. However, the
Pennsylvania Department of Agriculture statistics (PDA 1994) indicate that
approximately 50 percent of the fluid milk produced is used in the production
of dairy products. Therefore, from Table 21, a total of 16.2 million pounds of
locally produced fluid milk is available for consumption annually in the three-
county area surrounding the WTI facility.
Based on age-specific population data within the three-county area
(Table 14) and age-specific milk consumption rates (Table 18), the total annual
milk consumption in the three-county area is 57.9 million pounds. Therefore,
an additional 41.7 million pounds of milk are required from the large, non-
local processing plants to make up the shortfall (i.e., 57.9 million pounds
minus 16.2 million pounds). USDA (1988) data indicate that the three
counties surrounding the WTI facility accounted for approximately five percent
of the total milk processed in the non-local, federally inspected milk
processing plants in the Eastern Ohio-Western Pennsylvania milk marketing
area. Therefore, the total amount of milk that is produced locally and is
available for local consumption is 18.3 million pounds (i.e., 16.2 million Ibs
+ [0.05 x 41.7 million Ibs]).
The total amount of milk from locally raised cows represents 32
percent of the total milk consumption for the area surrounding the WTI facility
(i.e., 18.3 million lbs/57.9 million Ibs). Because data on milk products
(cheese, butter, etc) production are very limited for the three-county area
surrounding the WTI facility, the fraction of milk products consumed that is
derived from locally raised cows was also assumed to be 0.32. The high-end
value of the fraction of milk consumed that is derived from locally raised cows
is assumed to be twice the average value.
Volume V External Review Draft
Appendix V-8 14 Do Not Cite or Quote
-------
For farmers, typical and high-end values for the fraction of milk and
milk products ingested from a local source of 0.44 and 0.75, respectively, are
derived from U.S. EPA (1990a) guidance, and are based on data for farm
families. It was also assumed that a subgroup of fanners may exist that derive
all their milk and milk products from their own farm (subsistence fanners). A
value of 1 (i.e., 100 percent) is applied for this exposure subgroup of
subsistence fanners.
6. Consumption of Locally-Grown Vegetables and Fruits
Exposure to chemicals may occur through the consumption of vegetables
grown in the vicinity of the facility. The extent of exposure to chemicals through this
pathway is dependent on: 1) the chemical concentration in the vegetables; 2) the
vegetable ingestion rate; 3) the fraction of vegetables ingested that comes from a local
source; and 4) the frequency and duration of exposure. Exposure factors for this
pathway are presented in Tables 22 and 23 and are discussed below.
Based on data collected by the East Liverpool Board of Health for the area
surrounding the facility, approximately 30 percent of the local residents have home
gardens. This exposure pathway applies only to that portion of the residential
subgroup. Exposure is also assessed for local farmers.
a. Vegetable and Fruit Consumption Rate
Median total fruit and total vegetable consumption rates for children (1
to 6 years old), school children (7 to 12 years old), and adults, obtained from
the 1987-88 USDA (1993a) survey are summarized in Table 24. For children,
median total fruit and total vegetable consumption rates are estimated based on
a weighted average of consumption rates for 1 to 2-year-old and 3 to 5-year-
old children (based on the percentage of the survey population in each group).
Total fruit and total vegetable consumption rates for school-aged children are
based on weighted averages for 6 to 11-year-old girls and 6 to 11-year-old
boys. Adult consumption rates are based on the weighted average of adult
(older than 20 years) males and females.
Vegetable consumption was assumed to be divided among four
vegetable types:
1) Root vegetables - including below ground vegetables, such as
carrots, potatoes, and onions;
Volume V External Review Draft
Appendix V-8 15 DO Not Cite or Quote
-------
2) Leafy vegetable - including vegetables with leafy, edible
surfaces exposed to the atmosphere, such as lettuce and
broccoli;
3) Above ground protected - including vegetables with the edible
surface not exposed to the atmosphere, such as corn; and,
4) Above ground exposed - including non-leafy vegetables with
edible surfaces exposed to the atmosphere, such as tomatoes and
green peppers.
The distribution of consumption rates for these different categories of
vegetables and fruits are estimated based on consumption rates (in units of g
food/kg body weight/day) for more than 100 fruits and vegetables in the
Dietary Risk Evaluation System (DRES) compiled by U.S. EPA. DRES was
developed by the Office of Pesticide Programs (OPP) based on a 1977-78
USDA (1982) food consumption survey. A copy of these data were obtained
from OPP and were analyzed to estimate the relative consumption rates of the
total fruit and total vegetable categories. Based on these data, an individual's
vegetable diet is estimated to be comprised of 38 percent root vegetables, 13
percent leafy vegetables, 16 percent protected vegetables, and 33 percent
exposed vegetables. For fruits, only two types are identified: protected and
exposed. The distribution of fruit consumption between these two types is
estimated to be 58 percent protected and 42 percent exposed, based on an
evaluation of DRES.
High-end fruit and vegetable consumption rates are not available from
the USDA (1993a) data. Therefore, to estimate the upper end of the fruit and
vegetable consumption distributions, a method recommended by FDA (1993) is
applied in which the estimated median consumption rates are multiplied by an
estimated 90th percentile consumption rate to median consumption rate ratio.
Actual total fruit or total vegetable consumption distributions are not available;
however, FDA (1993) estimates that the 90th percentile to median ratios for
foods, in general, are typically in the range of 2.0 to 3.0. In addition, a
review Pao et al. (USDA 1982) consumption rate distribution data for several
individual fruits and vegetables (i.e., not all fruits and vegetables combined),
indicated that the 90th percentile to median ratio for these individual fruits and
vegetables generally fell in this range. For total fruits and total vegetables,
therefore, a 90th percentile to median ratio of 2.5 is used. The estimated

r
high-end total fruit and total vegetable consumption rates are shown in Table
24.
b. Exposure Frequency
The USDA consumption data are based on daily consumption of
vegetables; therefore, the exposure frequency is assumed to be 350 days per
year as recommended by U.S. EPA (1991).
c. Fraction Ingested from Contaminated Source
The fraction of an individual's vegetable diet that is homegrown is
estimated based on data collected by the East Liverpool Board of Health in a
local vegetable garden survey. These data indicate that typically 25 percent of
a gardening individual's total vegetable diet is homegrown (50th percentile of
respondents). A high-end estimate based on the 90th percentile of respondents
indicates that 50 percent of a gardening individual's total vegetable diet is
homegrown.
For fruits, more that 90 percent of the respondents indicated that less
than 25 percent of their fruit diet was homegrown; therefore, a value of 25
percent is used for the high-end value. For the typical value, it is estimated
that 12.5 percent (i.e., half of the high-end value) of an individual's fruit diet
is locally grown.
No data for farm families are available; therefore, the values cited
above for families with gardens are used. It is also assumed that a subgroup
of farmers may exist that derive all their vegetables from their own farm. A
value of 1 (i.e., 100 percent) is applied for this exposure subgroup of
subsistence farmers.
7. Ingestion of Fish
As indicated in the HHRA (Chapter VII, Section C.2), it is unlikely that local
residents are exposed to fish caught locally to a significant degree; however, a
subgroup within the local population that derives 100 percent of their fish diet from
locally caught fish (referred to as subsistence fishermen) may exist. It should be
noted; however, that no data or information are available to confirm the existence of
this subgroup.
The following factors must be considered when estimating exposure to this
subgroup: 1) the chemical concentration in fish; 2) the rate of fish ingestion 3) the
fraction of fish consumed that were caught locally; and 4) the frequency and duration
Volume V External Review Draft

-------
of exposure. Values of the exposure factors for this pathway are presented in Table
25. The fish ingestion rate for this subgroup is based on consumption values for
recreational fishermen presented by U.S. EPA (1990a). A fish consumption rate of
30 mg/day is used for the typical value, 140 tag/day as the high-end value. In
addition, it is assumed that 100 percent of fish consumed are from the study area.
8. Ingestion of Surface Water During Swimming
It is possible that local residents and fanners may ingest surface water while
swimming in local surface water bodies. This water may be contaminated and may,
therefore, be a source of exposure to chemicals. The extent of exposure to
contaminated surface water depends upon: 1) the concentration of chemical in the
surface water; 2) water ingestion rate; and 3) the exposure time, frequency, and
duration. The values of the exposure factors for this pathway are presented in Tables
26 and 27 and are discussed below.
a. Ingestion Rate
U.S. EPA (1990a) provides limited data concerning ingestion of surface
water during swimming. A value of 0.05 L/hr (50 mL/hr) is assumed to
apply. This value is applied as both the typical and high-end surface water
ingestion rate for all exposure subgroups.
b. Exposure Time and Frequency
U.S. EPA (1992b) recommends typical and high-end exposure time
values of 0.5 hr/day and 1 hr/day, respectively. In addition, typical and high-
end exposure frequency values of 5 days/year and 150 days/year are suggested
(U.S. EPA 1992b). The U.S. EPA document notes, however, that these data
are based on judgment. As indicated in Chapter VIQ, this pathway does not
appear to present significant risk. No further effort, therefore, to collect site-
specific data was put forth.
9. Dermal Contact with Surface Water During Swimming
It is possible that local residents and farmers may swim in local bodies of
surface water and be exposed to chemicals from the water through dermal contact.
The extent of exposure to contaminated surface water depends upon: 1) the dose per
swimming event (which is based on the chemical concentration in surface water, the
permeability coefficient of the chemical, and the duration of the swimming event); 2)
skin surface area; and 3) the exposure frequency and duration. The values of the
Volume V External Review Draft
Appendix V-8 18 Do Not Cite or Quote
-------
exposure factors for this pathway are presented in Tables 28 and 29 and are discussed
below.
a. Absorbed Dose per Event
U.S. EPA (1992b) recommends two methods for estimating the
absorbed dose associated with dermal exposure to substances during
swimming. For inorganic compounds; a steady-state approach is
recommended using the following equation:
= (Kp)(CW)(ET) (V-9-1)
where:
DA^, = absorbed dose per swimming event, mg/cm2-event
Kp = permeability coefficient from water, cm/hr
CW = concentration in surface water, mg/cm3
ET = exposure time of event, hr/event
The value of Kp is estimated to be 0.001 cm/hr, as recommended by U.S.
EPA (1992b). The concentration in surface water is estimated as described in
Appendix V-7. U.S. EPA (1992b) recommends typical and high-end exposure
time values of 0.5 hr/day and 1 hr/day, respectively.
For organic compounds, U.S. EPA (1992b) recommends a non-steady-
state method of estimating DA^,, as described in, Dermal Exposure
Assessment: Principles and Applications (U.S. EPA 1992b). This
methodology is used in the HHRA. The value of the permeability coefficient,
Kp, for organic compounds is chemical-specific. Non-steady state values of Kp
are estimated based on a methodology suggested by U.S. EPA (1992b) and are
presented in Table 30 for the substances of potential concern. The use of the
non-steady-state methodology is recommended by U.S. EPA because of the
generally brief duration of exposure events.
b. Skin Surface Area
It is assumed that during swimming, the entire body surface would be
exposed to the surface water. Age-specific body surface areas of 18,150 cm2
for adults, 7,200 cm2 for children, and 10,400 cm2 for school-age children,
were compiled from U.S. EPA (1990a) guidance.
Volume V External Review Draft
Appendix V-8 19 Do Not Cite or Quote
-------
c. Exposure Frequency
Typical and high-end exposure frequency values of 5 days/year and 150
days/year are recommended (U.S. EPA 1992b). As indicated in Chapter Vm,
this pathway does not appear to present significant risk. No further effort,
therefore, to collect site-specific data was put forth.
10. Ingestion of Breast Milk
It is possible that breast-feeding infants living in the vicinity of the facility may
be exposed indirectly to chemical emissions from the stack through irigestion of
contaminated breast milk. The magnitude of exposure for this pathway is based on
the following: 1) concentration of chemical in breast milk; 2) ingestion rate; 3) the
exposure duration; and 4) the body weight of the infant. Based on Smith (1987),
typical and high-end ingestion rates of breast milk of 700 g/day and 850 g/day were
estimated. Typical and high-end exposure durations for breast feeding of 90 days and
365 days, respectively, are estimated. Average and high-end body weights for an
infant are estimated to be 6 kilograms and 9 kilograms, respectively. Values of the
exposure factors for this pathway are presented in Table 31.
11. Ingestion of Meat from Locally Hunted Deer
It is possible that individuals hunting in the area surrounding the WTT facility
and consuming meat from deer hunted in these areas may be indirectly exposed to
substances released from the WIT facility stack. The magnitude of exposure for this
pathway is based on the following: 1) concentration of chemical in deer meat;
2) ingestion rate; and 3) the exposure duration. Values of the exposure factors for
this pathway are presented in Table 32.
An ingestion rate of 15 g/day is estimated based on the deer harvest (ODNR
1994; PDNR 1994; WVDNR 1994a, personal communication) hi the three counties
(Columbiana, Beaver, and Hancock) surrounding the WIT facility, the number of
hunting licenses issued (ODNR 1994; PDNR 1994; WVDNR 1995; personal
communication) in each of these three counties, and an estimate of 40 pounds of meat
per deer (WVDNR 1994). Table 33 summarizes these values and the estimated
amount of available deer meat in the three county area. Assuming that the amount of
deer meat available is divided equally amongst all hunters with licenses, the average
deer meat consumption rate is 15 g/day. A high-end value of 100 g/day is estimated
based on the assumption that an individual hunter might consume the meat from two
deer over the period of a year. The exposure duration for a resident, 9 and 30 years
for the average and high-end, respectively, is assumed to apply to the hunter.

calendar year available.
This value is an estimate of the number of Pennsylvania-bred cattle that are slaughtered in the state. 740 thousand head
slaughtered annually in two large, eastern Pennsylvania slaughter houses are not included in this number.
Calf slaughter data were not available for West Virginia; it was assumed that 15 percent of the calves born were
slaughtered, based on the avenge of Ohio and Pennsylvania data.

SUMMARY OF MILK MARKETING DATA
This appendix summarizes milk marketing data obtained from a number of sources
and identifies its use in developing estimates of milk distribution in the risk assessment study
area. These milk marketing/distribution data are used to develop an estimate of the fraction
of milk consumed by local residents that is derived from locally raised cows. The area of
interest for which data were collected was limited to the three counties (Columbiana, Ohio;
Beaver, Pennsylvania; and Hancock, West Virginia) in the immediate vicinity of the WTI
facility to coincide with the risk assessment study area.
Milk marketing data compiled from the Departments of Agriculture in Ohio,
Pennsylvania, and West Virginia are summarized in Table 1. These data include information
on local consumption (e.g., on farm) and milk marketing to plants/dealers and directly to
consumers. Discussions with the agricultural extension agents in Columbiana County, Ohio;
Beaver County, Pennsylvania; and Hancock County, West Virginia (personal
communication), indicated that milk that is marketed to plants and dealers (shown in Table 1)
/"""^ is divided between large processing facilities that are not generally located in the area and
^ smaller, local processing facilities that generally service communities within 5 to 10 miles of
the processing facility.
To estimate the distribution of milk between the large processing facilities and the
local handlers, a USDA (1988) milk marketing report that summarizes county-by-county and
state contributions to federally inspected milk processing plants (these are the large
processing facilities referred to above) was reviewed. Federally inspected milk processing
plants are assigned to different "milk marketing areas" under the Federal Milk Marketing
Order. In general, milk produced within a milk marketing area stays within the area (USDA
1994). However, these marketing areas are generally very large. For example, the Eastern
Ohio-Western Pennsylvania milk marketing area covers the eastern third of Ohio, the western
third of Pennsylvania, and the West Virginia panhandle. USDA milk marketing data for this
area are reviewed to estimate the fraction of milk produced in the area surrounding the WTI
facility that is sent to the large, federally inspected milk processing facilities contained within
the Eastern Ohio-Western Pennsylvania milk marketing area.
Based on milk marketing data for Beaver County, Pennsylvania (USDA 1988) and
milk production data for the same year (PDA 1994), it was estimated that approximately 85
^^ percent of the milk produced in Beaver County in December 1988 was processed in the
V r^ federally inspected plants (i.e., 15 percent remains local). No data were available for the

other two counties (Columbiana and Hancock); therefore, Beaver County data was assumed
to apply to the entire three-county area. Table 2 presents the estimated amount of milk that
is produced and remains in the three-county area surrounding the WIT facility.
To estimate the amount of locally derived milk that is available for consumption in
the area surrounding the WIT facility, the milk that remains local (including milk consumed
on farm, milk sold directly to consumers, and milk processed locally) is compared to the
total annual consumption in the three-county area surrounding the facility. The amount of
milk that remains local is estimated in Table 2 as 32.3 million pounds. However, the
Pennsylvania Department of Agriculture statistics (PDA 1994) indicate that approximately 50
percent of the fluid milk produced is used in the production of dairy products. Therefore,
from Table 2, a total of 16.2 million pounds of locally produced fluid milk is available for
consumption annually in the three-county area surrounding the WIT facility. Based on age-
specific population data within the three-county area (Table 3) and age-specific milk
consumption rates (Table 4), the total annual milk consumption in the three-county area is
57.9 million pounds. Therefore, an additional 41.7 million pounds of milk are required from
the large, non-local processing plants to make up the shortfall (i.e., 59.7 million pounds
minus 16.2 million pounds). USDA (1988) data indicate that the three counties surrounding
the WIT facility accounted for approximately five percent of the total milk processed in the
non-local, federally inspected milk processing plants in the Eastern Ohio-Western
Pennsylvania milk marketing area. Therefore, the total amount of milk that is produced
locally and is available for local consumption is 18.3 million pounds (i.e., 16.2 million Ibs +
[0.05 x 41.7 million Ibs]). The total amount of milk from locally raised cows represents 32
percent of the total milk consumption for the area surrounding the WIT facility (i.e., 18.3
million lbs/59.7 million Ibs). Because data on milk products (cheese, butter, etc) production
are very limited for the three-county area surrounding the WIT facility, the fraction of milk
products consumed that is derived from locally raised cows is also assumed to be 0.32.
