EXECUTIVE SUMMARY

Anderson Geneva, LLC/Ice Castle Retirement Fund, LLC (Anderson Geneva) and United States
Steel Corporation (USS) have established Corrective Action Levels (CALs) for preliminary
chemicals of interest (PCOIs) in shallow groundwater underlying the former Geneva Steel
facility in Vineyard, Utah (Site). The CALs have been developed based on risk to human health
associated with exposure to chemicals in groundwater, background levels of chemicals in
groundwater, and regulatory limits (i.e., maximum contaminant levels [MCLs]). CALs are not
intended to evaluate ecological receptors.
CALs presented in this document were derived as a screening tool to assist in planning and
decision making for Site redevelopment. CALs are limited to on-site exposures to groundwater.
They represent a baseline for on-site exposure; with the underlying condition that groundwater in
the shallow unconfined aquifer will not be used for domestic or industrial purposes. Therefore,
the only potentially complete groundwater-related exposure pathways are:
 Inhalation of volatile organic compounds (VOCs) in indoor air volatilizing from shallow
groundwater by residents and industrial/commercial workers.
 Inhalation of VOCs in trench air by construction workers and limited (if any) incidental
ingestion and dermal contact with chemicals in groundwater where excavation reaches
the water table.
 Incidental ingestion of and dermal contact by adolescent recreators with chemicals in
surface water that receives groundwater discharge.
In accordance with the Verification Investigation Work Plan (VIWP) (USS et al., 2017), site-
specific background upper tolerance limits (UTLs) have been established for inorganic chemicals
in shallow groundwater using groundwater chemistry data from wells along the eastern perimeter
of the Site. These background UTLs were calculated using statistical methods given in U.S.
Environmental Protection Agency (USEPA) guidance.
Site groundwater quality data will be compared to the CALs listed in this document as follows:
(1) for an organic PCOI, the CAL will be the greater of the risk-based CAL or federal MCL; (2)
for an inorganic PCOI, the CAL will be the greatest of the risk-based CAL, background-based
CAL (derived from UTLs), or federal MCL. CALs will be used to focus on specific PCOIs in
site-wide groundwater and on specific areas of the Site where PCOIs in groundwater may be a
concern, assuming no domestic or industrial use of shallow groundwater.
The CALs can be used as final remediation goals if the future land use or exposure scenarios are
consistent with the assumptions used for deriving CALs. However, as Site redevelopment plans
Groundwater Corrective Action Levels

are established, area-specific groundwater CALs may be prepared as part of the Tier 2 human-
health risk assessment process.
As discussed above, the risk-based CALs presented herein represent the baseline for on-site
exposure to shallow groundwater in the absence of any Site controls other than the limitations on
domestic or industrial use. Site control measures such as the use of health and safety plans
during construction, hard-piping existing ditches and streams during Site redevelopment,
implementation of vapor-intrusion controls, or other management practices and controls can
reduce or eliminate the exposures quantified in this document.

1.0 INTRODUCTION

Groundwater Corrective Action Levels (CALs) are chemical-specific concentrations estimated
for the protection of potential human receptors exposed to chemicals in groundwater that are
present in or migrating from shallow groundwater underlying the former Geneva Steel facility in
Vineyard, Utah (Site). CALs are only applicable for on-site exposures to groundwater. The
CALs presented in this document were developed based on risk associated with exposure of
human receptors to chemicals in groundwater, background levels of chemicals in groundwater,
and regulatory limits (i.e., maximum contaminant levels [MCLs]). CALs are not intended to
evaluate ecological receptors.
Groundwater in the shallow unconfined aquifer underlying the property is currently not used for
domestic or industrial purposes. Over-all land development for this Site anticipates the use of
deep wells (deeper than the shallow unconfined aquifer), upgradient springs, or other sources for
drinking, culinary, irrigation or other on-site purposes. Further, lawful use of the shallow
groundwater is not anticipated in the future for the following reasons:
 Municipal water systems will provide water to all users, domestic and industrial, on the
former Geneva Steel property.
 Groundwater in the shallow unconfined aquifer is of limited quantity and generally low
quality.
 Water rights in this area are fully subscribed, i.e., the State Engineer will not issue a new
water right for the Northern Utah Valley and Provo River Area because “all supplies of
water are fully appropriated” (Utah Division of Water Rights website, April 18, 2008).
Therefore, any use of the shallow groundwater would be unlawful.
Risk-based CALs for human receptors were developed based on non-drinking water use
associated with recreational, residential, industrial/commercial, and construction worker land use
scenarios.
The deep aquifer at the Site has not been impacted by Site-related releases. Therefore, the CALs
derived for the Site apply to groundwater in the shallow aquifer underlying the property. As the
depth to the base of the shallow aquifer is approximately 100 feet (ft) below ground surface, the
CALs apply to on-site groundwater within 100 ft of the ground surface.
The CALs presented herein were derived as a screening tool to assist in planning and decision
making for Site redevelopment. They represent a baseline for on-site exposure; with the
underlying condition that groundwater in the shallow unconfined aquifer will not be used for
domestic or industrial purposes. CALs will be used to focus on specific preliminary chemicals
of interest (PCOIs) in site-wide groundwater and on specific areas of the Site where PCOIs in
groundwater may be a concern. The CALs can be used as final remediation goals if the future

land use or exposure scenarios are consistent with the assumptions used for deriving CALs.
However, as Site redevelopment plans are established, area-specific groundwater CALs may be
prepared as part of the Tier 2 human-health risk assessment process.

2.0 METHODOLOGY

CALs for the Site were established using the three-step procedure indicated below:
Step 1 –PCOIs Identification (Section 2.1)
Step 2 – Conceptual Site Model (CSM) Development (Section 2.2)
Step 3 – CAL Derivation
– Risk-Based CALs (Section 2.3)
– Background-Based CALs (Section 2.4)
These procedures are discussed in detail below. The resulting CALs are discussed in Section 3.0
and presented in Tables 8 and 9.
2.1 Preliminary Chemicals of Interest Identification
The objective of Step 1 was to develop a list of PCOIs for which CALs were to be derived. For
this evaluation, PCOIs were primarily defined as those chemicals reported in groundwater from
at least one shallow groundwater sampling location at levels exceeding site-specific screening
levels (SSSLs) presented in Table 4-2 of the Verification Investigation Work Plan (VIWP) (USS
et al., 2017). SSSLs for water were established primarily based on concentrations protective of
the use of groundwater for potable purposes including ingestion of drinking water and inhalation
of volatile organic compounds (VOCs) volatilizing into indoor air during household use of water
(e.g., U.S. Environmental Protection Agency [USEPA] Regional Screening Levels [RSLs] for
tap-water) [USEPA, 2017a], or the federal maximum contaminant level goals [MCLGs]
promulgated under the Safe Drinking Water Act [USEPA, 2009b]). The laboratory practical
quantitation limit (PQL) was adopted as the SSSL in the absence of an RSL or MCLG, or if an
RSL/MCLG for a chemical was less than its PQL.
SSSLs were not specifically established to be protective of vapor intrusion of VOCs to indoor air
or to air in a trench. It is logical that groundwater that would be safe to drink and use as
household water by residents would also generally be safe to run beneath buildings. However, to
be conservative, SSSLs for VOCs detected in groundwater at the Site were compared to site-
specific groundwater CALs that are protective of indoor air concentrations (i.e., GW IA CALs)
for a residential property (USEPA, 2017a) (Table D-1, Appendix D). A subset of VOCs in
groundwater at the Site that (1) have SSSLs higher than GW IA CALs or that (2) do not have
both SSSLs and groundwater IA CALs were identified for further evaluation (Table D-1).
Among that subset of VOCs, additional PCOIs were identified as VOCs reported in groundwater
from at least one shallow groundwater sampling location at levels exceeding GW IA CALs or
VOCs that do not have both SSSLs and GW IA CALs (Table D-1). These PCOIs were
considered to be of potential concern for inhalation routes of exposure.

Based on the screening of the groundwater data to SSSLs and identification of additional
chemicals that may be a concern for inhalation routes of exposure, only a limited number of
analytes were identified as PCOIs (Table 1). CALs were developed for this group of chemicals.

*Maximum detected concentration was less than aqueous SSSL; however, the VOC may be a concern for inhalation routes of
exposure (Table D-1 in Appendix D). Therefore, the VOC was retained as a PCOI for calculation of risk-based CALs for
indoor air and air in a trench. ** Chemical was retained for programmatic purposes even though the maximum detected
concentration was lower than the aqueous SSSL.
2.2 Conceptual Site Model Development
The second step in the derivation of the CALs was the development of the CSM for the Site.
The CSM describes the likely pathways for transporting chemicals in groundwater from source
areas to locations of potential receptors, and exposure routes for receptors to contact with
chemicals in groundwater underlying the property or surface water downgradient from the
property. Risk-based CALs were only derived for shallow groundwater exposure pathways
identified as potentially complete in the CSM.
Described below is the CSM for the Site. A schematic presentation of the CSM is included as
Figure 1.
2.2.1 Known and Suspected Sources of Contamination and Release Mechanisms
Based on Site process knowledge, Site history, and the results of the previous investigations, the
potential sources of PCOIs in shallow groundwater are primarily associated with past industrial
operations. Potential sources may also include nearby urban areas and the natural occurrence of
certain inorganic PCOIs.
2.2.2 Secondary Sources
Surface and subsurface soil and groundwater that have been impacted may act as secondary
sources of PCOIs through release mechanisms such as leaching, infiltration/percolation from soil
to groundwater, groundwater discharge to surface water, and surface runoff of chemicals in soil
to surface water.
2.2.3 Release Mechanisms and Transport Pathways
Release mechanisms and transport pathways were evaluated on a Site-wide basis for the
development of groundwater CALs. Listed below are potential cross-media release mechanisms
and transport pathways for PCOIs related to groundwater:
 PCOIs in subsurface soil may enter groundwater through leaching, infiltration and
percolation.
 PCOIs in groundwater may be transported to surface water and sediments through
groundwater discharge.
 PCOIs in shallow groundwater may be transported to indoor air via volatilization.
 PCOIs in shallow groundwater may be transported to ambient air via volatilization.

2.2.4 Receptors and Exposure Scenarios
The human receptors associated with the Site who might be exposed to chemicals from on-site
groundwater and surface water are briefly described in the sections that follow.
2.2.4.1 Exposure to Volatile PCOIs in Indoor Air
Industrial/Commercial Land Use Scenario: On-site Indoor Workers
As mentioned earlier, the shallow unconfined groundwater underlying the property is currently
not used for industrial purposes, nor is its lawful use for such purposes allowed in the future.
Indoor workers are defined as future on-site industrial/commercial employees involved with non-
intrusive, operational activities that do not require excavation into soil beyond a depth of 1 ft. It
is highly unlikely that these workers would have direct contact with shallow groundwater.
However, it is possible that volatile PCOIs may be transported from shallow groundwater to
indoor air (vapor intrusion). Therefore, risk-based CALs for indoor workers exposed to volatile
PCOIs in indoor air were developed.
Residential Land Use Scenario: On-site Residents
As mentioned earlier, the shallow unconfined groundwater underlying the property is currently
not used for domestic purposes, nor is its lawful use for such purposes allowed in the future.
However, future on-site residents may potentially be exposed to volatile PCOIs transported from
shallow groundwater to indoor air (i.e., the vapor intrusion pathway). Therefore, risk-based
CALs were derived for exposure to volatile PCOIs in indoor air.
2.2.4.2 Exposure to Volatile PCOIs in Ambient Air
Industrial/Commercial Land Use Scenario: On-site Outdoor Workers
Outdoor workers are defined as workers completing outdoor maintenance tasks that are non-
intrusive and are only associated with the top 1 ft of soil. Because, PCOIs in shallow
groundwater have the potential to be transported from the subsurface to the surface via
volatilization, outdoor workers were considered as potential receptors for volatile PCOIs
detected in shallow groundwater. However, potential risks associated with the inhalation of
PCOIs volatilizing from groundwater into ambient air are expected to be negligible compared to
risks associated with the inhalation of volatile PCOIs in indoor air and air in a trench. Therefore,
risk-based CALs were not calculated for outdoor workers exposed to volatile PCOIs in ambient
air.
2.2.4.3 Exposure to PCOIs in Groundwater and Air in a Trench
Industrial/Commercial Land Use Scenario: On-site Construction Workers
It was assumed that construction activities or subsurface utility installation, maintenance, or
repair could take place at portions of the Site. Construction workers could potentially be
exposed to PCOIs in groundwater while completing work in excavated areas or trenches where
groundwater is encountered. The Occupational Safety and Health Administration (OSHA) has
established requirements for eliminating the accumulation of water in excavations in which
Groundwater Corrective Action Levels
Geneva Steel Facility, Vineyard, Utah March 16, 2018
Page 7
workers are present (29 CFR 1926 [OSHA, 2007]). It is unlikely that construction workers at the
Site will have significant direct exposure to groundwater in excavations due to OSHA
requirements and the common practice of eliminating the accumulation of water in excavations
in which workers are present. Therefore, the most likely scenario at the Site is that direct
exposure of construction workers to groundwater in a trench is an incomplete pathway. Under
that scenario construction workers may be exposed to PCOIs in shallow groundwater only via
inhalation of volatile PCOIs in trench air. However, to be conservative, calculations of risk-based
CALs for construction workers included hypothetical direct ingestion and dermal exposure to
groundwater, and exposure to volatile PCOIs in air in a trench.
2.2.4.4 Exposure to PCOIs in Surface Water
Recreational Use Scenario: On-site Adolescent Recreators
Because PCOIs in shallow groundwater have the potential to be transported to on-site surface
water bodies (flowing ditches, the Final Retention Pond [FRP], and Lindon Hollow Area
[LHA]), it was conservatively assumed that future adolescent recreators may be potentially
exposed to PCOIs from groundwater in surface water via incidental ingestion and dermal contact
pathways while wading. Furthermore, a conservative dilution factor of 10, based on USEPA
guidance for Environmental Indicator determinations (USEPA, 2007), was included to account
for dilution of the discharging groundwater with surface water. This factor may be modified for
a given Site surface water body as additional data become available. The inhalation pathway
was not factored into the CAL derivation due to the lack of equations/models for estimating
concentrations of chemicals volatilizing from surface water. It should be noted that potential
risks, if any, associated with the inhalation of PCOIs volatilizing from surface water are expected
to be negligible compared to risks associated with the ingestion and dermal contact pathways.
A summary of the human receptors for which risk-based CALs were calculated is presented in
Table 2.

2.3.1 Exposure Models Used to Calculate Shallow Groundwater Risk-Based CALs
Except for CALs calculated for the indoor air pathway, equations used to derive risk-based
CALs were selected primarily from those intake and risk characterization equations provided in
RAGS Part A (USEPA, 1989a), RAGS Part E (USEPA, 2004), and RAGS Part F (USEPA,
2009a). It is important to note that these parameters may be modified when site-specific
information (e.g., types of industrial activities performed and exposure time/frequency/duration)
becomes available and/or additional Site controls are considered for a given area of the Site.
Tables 3 through 7 identify the exposure parameters used to calculate the risk-based CALs for
each receptor. Tables 8 and 9 summarize the Site-specific CALs for the Site.

2.3.1.1 Indoor Air Pathway
Risk-based CALs for the indoor air pathway were estimated using USEPA’s on-line screening
tool, Johnson and Ettinger (JE) Vapor Intrusion Model ((USEPA, 2017a). The Final Guidance
for Assessing and Mitigating the Vapor Intrusion Pathway from Subsurface Sources to Indoor
Air (USEPA, 2015b) recommends using the on-line vaper intrusion screening level (VISL) tool
for conducting risk-based screening (USEPA, 2017b); however, VISLs are conservative generic
lookup screening levels that do not take into account Site conditions (e.g., the depth to
groundwater, groundwater temperature, soil type, etc.). The USEPA JE model was used to derive
site-specific groundwater CALs for both future on-site residential and industrial/commercial land
use scenario calculations. However, because the on-line JE model’s default calculations are
typically used for the residential exposure scenario only, several input parameters were modified
to reflect the future on-site industrial/commercial use. In addition, site-specific parameters were
used, when available.
Listed below are the input parameters selected based on site-specific consideration or the
potential future industrial/commercial land use scenario. The remaining parameters were based
on default values included in the on-line tool.
For both future on-site residential and industrial/commercial land use (based on site-specific
information)
 Soil type: Sandy loam
 Depth to groundwater: 8 ft ± 2 ft
 Groundwater Temperature: 18.56 degrees Celsius, based on the average temperatures
measured in the field during the groundwater investigations at the Site
For future on-site residential land use
 Building structure: Structure with basement
 Building mixing height: 12 ft (3.66 meters [m])
For future on-site industrial/commercial land use
 Building footprint: 25 m by 25 m (625 square meters [m2])
 Building structure: Slab-on-grade
 Air exchange rate: 0.83/hour, based on the American Society for Testing and Materials
(ASTM) default value for commercial buildings [ASTM E 2081-00 (Reapproved 2015),
ASTM 2015].
 Building mixing height: 8 ft (2.44 m)
 Exposure scenario: An exposure frequency of 250 days per year and exposure duration
of 25 years.

Inhalation toxicity values were updated in the JE model to match the values used to address other
inhalation exposure pathways (e.g., construction worker trench scenario). The route-to-route
extrapolation approach was not used because it is not recommended by USEPA due to
differences in physiological mechanisms following oral and inhalation routes of exposure. JE
model runs were not generated for the following chemicals even though they are volatile and
have inhalation toxicity values available: ammonia, cyanide, n-nitrosodimethylamine,
n-nitrosodi-n-butylamine, bromobenzene, bromomethane, cyclohexane, 1,2-dibromo-3-
chloropropane, and 2-hexanone. JE model addresses a limited list of chemicals and appropriate
surrogates (i.e., chemicals with similar molecular structure) were not available. However,
surrogates (in parenthesis) were used for the following chemicals: 1,3-dichlorobenzene (1,2-
dichlorobenzene) and 4-isopropyltoluene (isopropylbenzene). For some chemicals, the risk-based
groundwater indoor air CAL exceeded the water solubility limit; the letter “S” is used to indicate
what groundwater CALs were replaced with the water solubility limit.
Table 9 presents the residential and indoor worker groundwater CALs that are protective of the
indoor air exposure pathway. Tables D-1 and D-2 in Appendix D presents the risk-based screen
results of the site-wide maximum detected concentrations with the indoor CALs for the on-site
resident and on-site indoor worker, respectively.
Output files for the JE model runs are shown in Appendix A.
2.3.2 Toxicity Values Used to Calculate Shallow Groundwater CALs
Toxicity values used to calculate risk-based CALs for adolescent recreators and construction
workers were identified as discussed here. The toxicity value is divided into two categories:
carcinogenic and non-carcinogenic effects. Potential health effects are evaluated separately for
these two categories, because their toxicity criteria are based on different mechanistic
assumptions and associated risks are expressed in different units. Carcinogenic toxicity values
are expressed as slope factors (SFs) and inhalation unit risk (IUR) and noncarcinogenic toxicity
values are expressed as reference doses (RfDs) and inhalation reference concentrations (RfCs).
Because the VIWP provides a detailed discussion of these chemical toxicity values, this topic
will not be discussed in detail for this document. However, the sources of the toxicity values
used to estimate risk-based CALs were selected in accordance with USEPA guidance (2003) as
summarized below:
 Tier 1 – Integrated Risk Information System (IRIS), available on-line at
https://www.epa.gov/iris
 Tier 2 – USEPA’s Provisional Peer-Reviewed Toxicity Values (PPRTVs) at
https://hhpprtv.ornl.gov/
 Tier 3 – Other Toxicity Values (e.g., California Environmental Protection Agency at
https://oehha.ca.gov/chemicals; The Agency for Toxic Substances and Disease Registry

Assessment Summary Tables [HEAST] at https://epa-heast.ornl.gov/ [USEPA, 1997]).
Speciation data have shown that nearly all chromium at the Site is trivalent chromium.
Therefore, risk-based CALs for total chromium were derived using toxicity values for trivalent
chromium. When available, subchronic noncarcinogenic toxicity values from the Oak Ridge
National Laboratory (ORNL) Risk Assessment Information System (RAIS) at
https://rais.ornl.gov/ (ORNL, 2017), PPRTV on-line database, and HEAST (USEPA, 1997) were
used to calculate risk-based CALs for the construction worker scenario.
Because of its unique mode of action, USEPA has not estimated toxicity values for lead.
Therefore, USEPA lead models protective of blood lead levels in children, adults, and fetuses
were used to derive risk-based CALs for lead (Appendix E).
For chemicals that do not have standard toxicity values (i.e., toxicity values obtained from the
sources listed above), but that were identified as PCOIs based on the screening against SSSLs,
risk-based CALs from surrogate chemicals were used. The surrogate chemicals were assigned
based on similarities in chemical structure and are listed below:
PCOIs Surrogate Chemical
Acenaphthylene Acenaphthene
Benzo(ghi)perylene Pyrene
4-Bromophenyl phenyl ether Bis (2-chloroisopropyl)ether
4-Chlorophenyl phenyl ether Bis (2-chloroisopropyl)ether
1,3-Dichlorobenzene 1,2-Dichlorobenzene
1,2-Dichloroethene (total) cis-1,2-Dichloroethene (most conservative)
trans-1,3-Dichloropropene 1,3-Dichloropropene
Dimethyl phthalate Diethyl phthalate
4-Isopropyltoluene Isopropylbenzene
1-Naphthylamine 2-Naphthylamine
2-Nitrophenol 2,4-Dinitrophenol
4-Nitrophenol 2,4-Dinitrophenol
Phenanthrene Anthracene
2-Picoline Pyridine

Table 10 identifies 28 volatile PCOIs that do not have standard chronic inhalation toxicity
values. Route-to-route toxicity values were not used to generate CALs because USEPA
discourages using this approach due to differences in physiological mechanisms following oral
and inhalation routes of exposure.
Groundwater Corrective Action Levels
Geneva Steel Facility, Vineyard, Utah March 16, 2018
Page 12
There is increased uncertainty in using the CAL approach at the Site, because there are volatile
PCOIs for which risk-based CALs could not be calculated (as discussed in Section 4).
2.3.3 Target Risk Goals
As shown in Table 8, risk-based CALs were derived based on the following target risk goals for
individual PCOIs:
 For carcinogenic effects: An incremental cancer risk of 1E-04 and 1E-06.
 For noncarcinogenic effects: A hazard quotient (HQ) of 1 based on single exposure
pathways.
2.3.4 Equations Used to Calculate Shallow Groundwater CALs
Equations used to estimate risk-based CALs incorporate both exposure assumptions and toxicity
values to estimate concentrations associated with an acceptable level of risk. These equations
are presented below for both carcinogenic and noncarcinogenic effects. As discussed in Section
2.3.1, risk-based CALs for the indoor air pathway were calculated using USEPA’s on-line JE
model. Accordingly, this section does not include equations for exposure to PCOIs in indoor air.
JE model output is documented in Appendix A.
2.3.4.1 Exposure to PCOIs in Open Trenches: Construction Workers
USEPA Region 8 developed a model to derive a volatilization factor that can be used to estimate
the upper bound exposure concentrations for workers in trenches flooded with groundwater off-
gassing VOCs (USEPA, 1999). The approach used is a box model that is typically used to
estimate air concentrations in enclosed spaces. For the development of a volatilization factor for
the trench model, the chemical concentration everywhere in the trench air compartment is
assumed to be constant. The VOC enters the box through emission from groundwater at the base
of the trench and leaves the box by wind-induced convection. The model assumes the
construction of a commercial building requires a trench length of 30 m and uses a calm wind
speed (0.45 m per second [m/s]). The number of air changes per day is conservatively estimated
at 0.015 m/s. It assumes uniform mixing of air in the trench. The generic volatilization factor
estimated using this approach is appropriate only for those VOCs with Henry’s Law Constants
greater than 1E-04 atmosphere – cubic meter per mole (atm-m3/mole). For the calculation of
risk-based CALs, this volatilization factor was conservatively used for all chemicals that were
identified as a volatile (i.e., Henry's Law constant greater than or equal to 1 × 10-5 atm-m3/mole
or a vapor pressure greater than or equal to 1 millimeter of mercury [mm Hg]) in the USEPA
RSL table and have inhalation toxicity values available. The construction worker CAL equations
and exposure parameters are listed below as well as provided in Appendix B.

2.4 Derivation of Background-Based CALs
A common approach for assessing the occurrence of contamination at a site is to first develop
background limits based on a statistical analysis of background data (i.e., data from upgradient
wells), and then to compare concentrations measured in samples from the site (i.e., downgradient
and interior wells) with the background limits. The statistical method used to establish
background limits for this comparison process is the upper tolerance limit (UTL) (USEPA,
1989b and 1992). The UTL represents the upper end of the background data distribution such
that a specified (high) percentage of constituent concentrations will be below the limit with a
specified degree of confidence if the constituent concentrations from the sample location are no
different than those from background. The USEPA guidance document suggests that a one-sided
95% tolerance interval with 95% minimum coverage is appropriate for this comparison (USEPA,
1989b).
In simple terms, the 95% UTL with 95% coverage can be interpreted as “I am 95% sure that
approximately 95% of individual population measurements fall below this upper limit.” The
underlying principle of the tolerance limit implies that a small percentage of the site area
concentrations would be expected to exceed the tolerance limit, even when the site area data are
drawn from the same population as the background data. Therefore, the results of future
comparisons of sample concentrations with the tolerance limit should be interpreted with
caution: exceedance of the UTL does not necessarily constitute evidence that site-related
contamination has occurred.
Section 4.2 of the VIWP provides for the development of Site-specific background UTLs for
inorganic chemicals. The VIWP states that background is considered to be represented by the
eastern perimeter wells.
The procedure used to calculate parametric tolerance limits is described in USEPA (1989b,
Pages 5-19 to 5-22). The main steps in calculating the UTL are as follows:
1. Compile a valid background data set. These data should be collected from an area that
has similar hydro-geo-chemical conditions to the site under evaluation and is unaffected
by the site operation. For this analysis, sample results from the following upgradient
wells were pooled to form an aggregate background data set:
Groundwater Corrective Action Levels
Geneva Steel Facility, Vineyard, Utah March 16, 2018
Page 25
 Perimeter-In Groundwater Monitoring Program (PGMP) wells MW-119S, MW-
120S, MW-121S, MW-122S, MW-123S, MW-124S, PZ-01S, PZ-01M, PZ-01D, PZ-
02S, PZ-02M, PZ-02D, PZ-03SR, PZ-03M, and PZ-03D. These wells are located
along the eastern boundary of the Site. Data from 1997 to 2007 were included. Note
that although PGMP monitoring wells MW-116S, MW-117S, and MW-118S are
located along the eastern boundary of the Site, data from these wells are not included
in the background data set, since the data show signs of impact related to localized
sources.
 Closed Hazardous Waste Impoundments (CHWI) wells MW-01, MW-10, and MW-
19D (monitoring wells designated as background in Attachment 5 of the Post-Closure
Permit for the Site). These wells are also located along the eastern boundary of the
Site. Data from 2001 to 2007 were included.
For this analysis, non-detections were used as they were reported in the project database.
2. Apply a normality test (such as the Shapiro-Wilk W test [USEPA, 1992]) to the
background data to check whether the data can be assumed to be normally distributed. If
a hypothesis of normality cannot be rejected at the 5% significance level, calculate the
UTL from:

Equation 17:
in which

3. If the data do not pass the normality test, apply the normality test to the log-transformed
data. If a hypothesis of normality based on the log-transformed data cannot be rejected at
the 5% significance level, calculate the UTL in the log scale by first using the equation
above and then back-transforming the limit to the arithmetic scale by taking the
antilogarithm.
4. If neither the raw nor the log-transformed data can be considered to be normally
distributed, or the percentage of nondetects is greater than 15%, the UTL is calculated
based on non-parametric assumption, as described in USEPA (1992).
5. If all background samples are non-detects, the UTL is not assessed and the reporting limit
may be used as a surrogate of UTL in the future.

The above methodology was applied to the upgradient groundwater data set for the inorganic
PCOIs identified in Section 2.1. Distributional testing and calculation of UTLs were performed
using NCSS®, a commercial software package available from Number Crunching Statistical
Systems (NCSS [Hintze, 2004]). The output files from NCSS for the background groundwater
data set are included as Appendix C.
With the exception of the total barium data set, which is lognormal, the inorganic background
data sets did not pass normality tests. Therefore, nonparametric methods were employed to
determine the background-based CAL, as a 95% UTL, for all inorganic PCOIs, with the
exception of total barium. The total barium 95% UTL was calculated according to step 3 above.
It is noted that because all background data for thallium were non-detections, the 95% UTL for
thallium was not assessed (see step 5 above). The background-based CALs are presented in
Table 8. In addition to the background 95% UTLs listed in Table 8, background 95% UTLs
were also statistically established for several other inorganic constituents that may be present in
background concentrations in Site groundwater. These 95% UTL background concentrations are
included in Appendix C.
2.5 Background Means Comparison
Another line of evidence that may be used to determine whether the SWMUs/SWMUGs
concentrations are elevated relative to background is two tail hypothesis testing. The testing
identifies whether the site mean is significantly above the background mean, if enough data are
available to run the statistical analysis (i.e., roughly 15 or more data points for each data set).
The threshold value for what defines a significant difference is determined by the significance
level (α) of the test, assuming the null hypothesis is “true” (i.e., SWMU/SMUG data set is
similar to background). For the former Geneva Steel facility, a significance level of α = 0.20 is
used (USEPA, 2002b).

3.0 PRESENTATION AND APPLICATION OF CALS

As discussed in Section 2.2.4, due to the current and planned future limitations on the use of the
shallow unconfined groundwater for potable domestic or industrial purposes, the only
groundwater-related exposure pathways that are potentially complete are:
 Inhalation of PCOIs volatilizing from shallow groundwater and entering indoor air by
residents.
 Incidental ingestion of and dermal contact by adolescent recreators with PCOIs in surface
water that receives groundwater discharge.
 Inhalation of volatile PCOIs in trench air by construction workers where excavation
reaches the water table.
 Limited (if any) incidental ingestion of and dermal contact with PCOIs in groundwater in
a trench by construction workers.
 Inhalation of PCOIs volatilizing from shallow groundwater and entering indoor air by
indoor industrial/commercial workers.
Table 8 presents the site-specific, risk-based CALs derived for the potential human receptors and
exposure scenarios identified in Section 2.2.4 based on the target risk goals described in Section
2.3.3. Site-specific, background-based CALs derived as discussed in Section 2.4 and chemical-
specific MCLs promulgated under the Safe Drinking Water Act are also presented on Table 8.
For the following carcinogenic PAHs, the calculated risk-based CAL for adolescent recreators
was less than the aqueous SSSL which was based on the method detection limit (MDL):
 Benzo(a)anthracene (MDL of 8.0E-04 mg/L)
 Benzo(a)pyrene (MDL of 8.0E-04 mg/L)
 Benzo(b)fluoranthene (MDL of 9.0E-04 mg/L)
 Dibenz(a,h)anthracene (MDL of 9.0E-04 mg/L)
 Indeno(1,2,3-cd)pyrene (MDL of 8.0E-04 mg/L)
 Benzo(a)pyrene equivalent (BaP Equivalent) (MDL of 8.0E-04 mg/L)
Therefore, the risk-based CAL for adolescent recreators exposed to these chemicals in
groundwater will be the MDL listed above.
Groundwater Corrective Action Levels
Geneva Steel Facility, Vineyard, Utah March 16, 2018
Page 28
The MDL range of 0.00019 - 0.0038 mg/L was selected as the aqueous SSSL for vinyl chloride;
the MDL-based CAL replaces the residential groundwater indoor air CAL (0.0031 mg/L) that
was derived for vinyl chloride which falls within the MDL range.
Groundwater CALs will be used to focus on specific PCOIs in site-wide groundwater and on
specific areas of the Site where PCOIs in groundwater may be a concern, assuming limitations of
domestic or industrial use of shallow groundwater.
The following process is used to determine the overall CAL for a specific volatile PCOI:
 Selection of the risk-based CAL is dependent on Site redevelopment plans and land use.
If land use is known, the appropriate risk-based CAL from Table 8 should be selected to
represent the CAL. In the absence of specified land use, the least of the residential,
industrial/commercial, construction worker, or adolescent recreator risk-based CAL
should be used to represent the risk-based CAL.
 The overall CAL for volatile PCOIs in groundwater is the greatest of the risk-based
CAL, the background-based CAL, or the federal MCL.
The following process is used to determine the overall CAL for a specific non-volatile PCOIs
(e.g., inorganics and semi-volatile organics):
 Exposure to non-volatile chemicals can only occur for the adolescent recreator and
construction worker scenarios. Adolescent recreator exposure may only occur at specific
existing surface water bodies such as LHA, the FRP, or the Denver and Rio Grande
(D&RG) ditch. No other pathway exists for direct exposure of adolescent recreators to
non-volatile PCOIs in shallow Site groundwater. Exposure to non-volatile PCOIs by
construction workers can occur at locations where groundwater might by contacted in a
trench.
 The overall CAL for adolescent recreator exposure to non-volatile PCOIs in existing
surface water bodies is the greatest of the risk-based CAL, the background-based CAL,
or the federal MCL. Shallow groundwater quality data for groundwater discharging to
on-site surface water bodies will be compared to this overall CAL.
 The overall CAL for construction worker exposure to non-volatile PCOIs in groundwater
is the greatest of the risk-based CAL, the background-based CAL, or the federal MCL.
Table 9 summarizes overall CALs for adolescent recreators, indoor industrial/commercial
workers, residents, and construction workers.

4.0 UNCERTAINTY ANALYSIS

JE model runs were not generated for the following chemicals even though they are volatile and
have inhalation toxicity values available: ammonia, cyanide, n-nitrosodimethylamine,
n-nitrosodi-n-butylamine, bromobenzene, bromomethane, cyclohexane, 1,2-dibromo-3-
chloropropane, and 2-hexanone. Site-specific groundwater CALs that are protective of the vapor
intrusion exposure pathway were not derived for these chemicals. Maximum detected
concentrations in site-wide groundwater were compared to the risk-based inhalation CALs for
the construction worker (Inh CW CALs) (Table 10); ammonia, cyanide, and 1,2-dibromo-3-
chloropropane have detections greater than the Inh CW CAL.
Risk-based indoor air groundwater CALs were not calculated for the following chemicals
because standard inhalation toxicity values were not available:
Volatile Chemicals Without Standard Inhalation Toxicity Values
Acenaphthene Dichloroethene, cis-1,2-
Acenaphthylene Trichlorobenzene, 1,2,3-
Anthracene Trimethylbenzene 1,3,5-
Benzo(ghi)perylene Chlorotoluene 2-
Fluorene Chlorotoluene 4-
Methylnaphthalene 2- Dichloroethene (total), 1,2-
Phenanthrene Dichloroethene, cis-1,2-
Pyrene Dichloroethene, trans-1,2-
Acetophenone Dichloropropane 1,3-
Bromophenyl phenyl ether, 4- Ethyl Ether
Chloronaphthalene 2- n-Butylbenzene
Chlorophenyl phenyl ether, 4- sec-Butylbenzene
Dibenzofuran tert-Butylbenzene
Picoline 2- trans-1,3-Dichloropropene
Pyridine Trichlorobenzene, 1,2,3-
Dichloroethene (total), 1,2- Trichlorofluoromethane

The inhalation toxicity values for 1,2,4-trimethylbenzene are the same for 1,3,5-
trimethylbenzene; the JE model results for 1,24-trimethyl benzene was used for 1,3,5-
trimethylbenzene to provide indoor air CALs for the on-site resident and on-site indoor worker.
Even though benzo(a)anthracene is identified as volatile and has inhalation toxicity values
available, USEPA (2017b) has determined that the chemical was not sufficiently volatile or toxic
enough to pose an inhalation risk. Therefore, the indoor air and inhalation of vapors in a trench
inhalation exposure pathways were not evaluated for benzo(a)anthracene.
Groundwater Corrective Action Levels
Geneva Steel Facility, Vineyard, Utah March 16, 2018
Page 30
In conclusion, risk-based CALs were not calculated for some volatile chemicals because the JE
model was not equipped to address the chemical, inhalation toxicity values were not available, or
the chemical was determined to be not sufficiently volatile or toxic enough to be evaluated. Per
USEPA (2009a) guidance, non-standard toxicity values were not derived by using route-to-route
extrapolation to evaluate the potential impact of these volatile chemicals to human health.
However, it is unlikely that these volatile chemicals would pose an unacceptable threat to human
health due to their relatively low concentrations in groundwater. With the exception of ammonia,
cyanide, and 1,2-dibromo-3-chloropropane that were detected above the Inh CW CAL; it is
unknown if these chemicals would also be PCOI for the vapor intrusion pathway (i.e., no JE runs
were possible).

5.0 SUMMARY

Based on the assumption that shallow groundwater at the Site will not be used as potable water
for residents or industrial workers, risk-based CALs were derived for potential non-potable
exposure to PCOIs in shallow groundwater. Also, because the Site is located downgradient of
substantial urbanized areas of Utah Valley, in accordance with the VIWP, it is appropriate to
consider background levels of PCOIs as background-based CALs for shallow Site groundwater.
For a given PCOI in groundwater, the CAL is the greatest of the risk-based CAL, background-
based CAL (inorganics only), or the federal MCL.
The CSM (Section 2.2) for shallow groundwater use indicates that, with the limitations on
potable use and the restrictions OSHA regulations place on construction work in excavations, the
only complete pathway for direct-contact exposure to PCOIs is adolescent recreators wading in
existing on-site surface water bodies. However, to be conservative, calculations of CALs for
construction workers included hypothetical direct ingestion and dermal exposure to PCOIs in
groundwater, as well as inhalation of volatile PCOIs in air in a trench.
Exposure to non-volatile PCOIs can only occur for the adolescent recreator and construction
worker scenarios. VOCs may be PCOIs for adolescent recreator, construction worker,
residential, and industrial/commercial worker scenarios.
The discussion above indicates that PCOIs in shallow groundwater will potentially be a concern
only in specific areas: 1) where volatile PCOIs are present in shallow groundwater at
concentrations above overall CALs, 2) where shallow groundwater with non-volatile PCOI
concentrations above overall CALs for adolescent recreators is discharging to an existing on-site
surface water body, and 3) where shallow groundwater with non-volatile PCOI concentrations
above overall CALs for construction workers may be contacted in a trench.
The risk-based CALs presented in this document represent the baseline for on-site exposure to
shallow groundwater in the absence of any Site controls other than the limitations on residential
or industrial potable use. Site control measures can reduce or eliminate the exposures quantified
in this document:
 In areas where overall CALs for the construction worker scenario are exceeded,
implementation of health and safety plans can reduce or eliminate direct contact and
inhalation hazards associated with PCOIs in shallow groundwater during construction
activities.
 Contact with groundwater during recreational use of on-site water bodies can be
eliminated by restricting access to existing ditches and streams (e.g., hard-piping) during
Site redevelopment.
Groundwater Corrective Action Levels
Geneva Steel Facility, Vineyard, Utah March 16, 2018
Page 32
 In areas where volatile PCOIs are present in shallow groundwater in concentrations
exceeding CALs, vapor intrusion into indoor air can be mitigated by engineered controls
such as vapor barriers or active or passive venting systems.
There may be cases where Site management controls may not be adequate, and corrective action
may be required for chemicals in groundwater in accordance with Utah Administrative Code
[UAC] R315-101-6(e). As Site redevelopment plans are established and implemented, the
baseline risk-based CALs presented in this document can be refined for selected areas using site-
specific values, where appropriate, for exposure parameters. Also, area-specific CALs may be
developed as part of the Tier 2 human-health risk assessment process.

Notes:
Shaded cells indicate that the risk-based CAL (highlighted above) is lower than the aqueous site-specific screening level (SSSL) based on the method detection limit (MDL). The MDL will replace the risk-based CAL for screening purposes. Table below presents the MDLs:
Chemical MDL (mg/L)
Benzo(a)anthracene 0.0008
Benzo(a)pyrene 0.0008
BaP Equivalent 0.0008
Benzo(b)fluoranthene 0.0009
Dibenz(a,h)anthracene 0.0009
Indeno(1,2,3-cd)pyrene 0.0008
Vinyl Chloride 0.00019 - 0.0038
(1) For chemicals that do not have readily available toxicity data, surrogate chemical toxicity data were used to derive risk-based CALs. For mixture chemicals (e.g., m- & p-xylene), the most conservative toxicity values were used to derive the risk-based CAL.
(2) Federal Maximum Contaminant Levels (MCLs) (USEPA, 2009).
(3) Project-specific 95% upper tolerance limit for background concentrations (See Appendix C).
(4) USEPA Groundwater Johnson and Ettinger Model Runs (See Appendix A). (S) indicates that the CAL is the water solubility limit.
(5) Based on speciation data at the Site, total chromium is assumed to be trivalent chromium.
(6) Risk-based CALs for lead were calculated using USEPA's Adult Lead Methodology and Integrated Exposure Uptake Biokinetic models (Appendix E)
(7) Thallium background concentrations were all non-detect; 95% UTL not calculated.
(8) The MCL for total PAHs was used.

Notes:
Shaded cells indicate that the risk-based CAL is a method detection limit (or range).
- = no value
CAL - corrective action levels
mg/L - milligrams per liter
PCOI - preliminary chemical of interest
No JE - Even though analyte is a volatile, it is not addressed in Johnson and Ettinger (JE) model
NVT - Not sufficiently volatile and/or toxic to pose inhalation risk in selected exposure scenario for the indicated medium
(1) Chemical meets the definition of a volatile where the henry's law constant (atm-m3/mole) > 1E-05 or the vapor pressure > 1 mmHg.
(2) For chemicals that do not have readily available toxicity data, surrogate chemical toxicity data were used to derive risk-based CALs. For mixture chemicals (e.g., m- & p-xylene), the most conservative were used to derive the risk-based CAL.
(3) USEPA Johnson and Ettinger model run results (see Appendix A). (S) indicates that the value is the water solubility limit (i.e., risk-based screening value was above the solubility limit).
(4) Subchronic inhalation toxicity values were available for these chemicals therefore the inhalation of trench vapors exposure pathway was evaluated.

> - greater than SSSL - Site-specific screening level
mg/L - milligrams per liter VOC - volatile organic compound
PCOI - preliminary chemicals of interest
(1) Surrogates are used as a source of toxicity values to derive screening levels when chemical-specific toxicity values are not readily available.
(2) U.S. Environmental Protection Agency (USEPA) 2017a Johnson and Ettinger on-line model runs (See Appendix A).
The GW IA CALs are protective of a target cancer risk of 1E-06 and a target hazard quotient of 1.

Calculation of CALs for Lead

Calculation of Risk-Based CALs for Lead

E.1 Introduction
The federal Maximum Contaminant Level (MCL) for lead of 0.015 milligrams per liter
(mg/L) (USEPA 2009) is an action level considered protective for domestic exposures
where people intentionally ingest large quantities of drinking water each day (e.g., 2 liters
(L)/day). However, shallow groundwater at the Site will not be used for domestic or
industrial purposes. Instead, direct exposure to groundwater at the Site is limited to
incidental ingestion of 0.005 L/day of groundwater for 45 days/year by
construction/utility workers and incidental ingestion of 0.05 L/day of surface water
potentially impacted by groundwater for 10 days/year by adolescent recreators.
Therefore, lead concentrations in groundwater protective of exposures of
construction/utility workers and adolescent recreators at the Site would logically be much
higher than 0.015 mg/L. Therefore, risk-based Corrective Action Levels (CALs) were
calculated that are protective of construction/utility workers and adolescent recreators
exposed to lead in groundwater.

E.2 Construction/Utility Workers
A site-specific risk-based CAL for lead in groundwater of 20 milligrams per liter (mg/L)
was calculated for construction/utility workers based on potential direct exposure to
groundwater in a trench. The risk-based CAL was calculated using the methodology in
the U.S. Environmental Protection Agency’s (USEPA’s) Adult Lead Methodology model
(ALM) (USEPA 2017a), modified for exposure to lead in water. Table E-1 shows
parameter values used to calculate the risk-based CAL for construction/utility workers.
Standard USEPA (2017a) default parameter values were used for fetal/maternal blood
lead ratio (Rfetal/maternal), 95th percentile blood lead concentration in fetus (PbBfetal,0.95,goal ),
and biokinetic slope factor (BKSF). USEPA (2017b) guidance recommends using a
geometric standard deviation (GSDi) of 1.8 (unitless) and a baseline blood lead (PbB0) of
0.6 micrograms per deciliter (µg/dL). Additional information on derivation of parameter
values for construction workers is discussed below.
The site-specific RME groundwater ingestion rate (IRw) of 0.005 L/day was used, based
on (1) incidental ingestion of 0.005 L/hour from accidental splashing or hand-to-face
contact while working and (2) an exposure time to groundwater in a trench of 1 hour/day.
The USEPA (2003a) default absorption fraction for soluble lead in adults (AFsoluble) of
0.2 was used for oral absorption of lead in groundwater (AFw). The site-specific RME
frequency of exposure to groundwater (EFw) of 45 days/year was used. The averaging
time (AT) was calculated using the following equation to account for short-term exposure
per USEPA lead guidance (USEPA, 2003b and 2016).

The ALM predicted that fetuses of construction/utility workers exposed to 18 mg/L of
lead in groundwater at the Site would have a 5% probability of exceeding the 10 µg/dL
blood lead level (BLL) threshold. For the former Geneva facility, a fetal lead blood
(PbBfetal,0.95,goal) of 10 µg/dL was used as the target criterion to limit the risk to no more
than a 5 percent chance of a fetus in a pregnant female worker having a BLL above 10
µg/dL (USEPA 2017c)..

E.3 Adolescent Recreators
Two site-specific risk-based CALs for lead in groundwater (7 and 33 mg/L) were
calculated for adolescent recreators (7-18 years of age) potentially exposed to lead via
direct exposure to surface water impacted by groundwater at the Site. The exposure
frequency to surface water for adolescent recreators of 2 days/month for 5 months does
not meet the USEPA minimum requirement for evaluating lead exposures of at least 1
day/week for 13 weeks (USEPA 2003b and 2016). Therefore, exposure frequency and
duration for adolescent recreators were adjusted to 1 day/week for at least 5 months for
calculation of the risk-based CALs for lead. Because the CALs for lead are protective for
adolescent recreators exposed for 1 day/week for at least 5 months, the CALs are also
protective for the site-specific exposure frequency of 2 days/month for 5 months.

The following equation was used to calculate the AT for the recreator to adjust the lead
model for short-term exposure (USEPA, 2003b and 2016):
Equation 3:
ܣݒ݁ݎܽ݃݅݊݃ ܶ݅݉݁ ሺܣܶሻ 151 ݀ܽݕݏ

ݕ݁ܽݎ

USEPA does not have a lead model for evaluating risk to adolescents. Therefore, risk-
based CALs for adolescent recreators were calculated using (1) USEPA’s ALM and (2)
USEPA’s Integrated Exposure Uptake Biokinetic (IEUBK) model. USEPA’s ALM is
protective of adults and of fetuses in pregnant adults (USEPA 2017a), and would
therefore be protective of older adolescent recreators at the Site. However, USEPA’s
ALM may not be protective of younger adolescent recreators. Therefore, a risk-based
3
CAL was also calculated for adolescent recreators using USEPA’s IEUBK model
(USEPA 2010) which is intended to be protective of young children 0-6 years of age.
E.3.1 ALM
A site-specific risk-based CAL of 65 mg/L for lead in groundwater for adolescent
recreators was calculated using the methodology in USEPA’s ALM (USEPA 2017a),
modified for exposure to lead in water. Table E-1 shows parameter values used to
calculate this risk-based CAL. Standard USEPA (2017a) default parameter values were
used for Rfetal/maternal, PbBfetal,0.95,goal, and BKSF. USEPA (2017b) guidance recommends
using a GSDi of 1.8 (unitless) and a PbB0 of 0.6 µg/dL. Additional information on
derivation of parameter values is discussed below.
The site-specific RME surface water ingestion rate of 0.05 L/day was used, based on (1)
USEPA’s (2011) incidental ingestion rate of 0.05 L/hour for swimming and (2) a site-
specific exposure time of 1 hour/day. The USEPA default AFw of 0.2 was used (USEPA
2003a). The site-specific EFw of 22 days/year and an AT of 151 days/year was calculated
(see Equations 2 and 3) to represent the recreational exposure period of May through
September.
The ALM predicted that fetuses of adolescent recreators exposed to 6 mg/L of lead in
surface water at the Site would have a 5% probability of exceeding the 10 µg/dL BLL
threshold. For the former Geneva facility, a fetal lead blood (PbBfetal,0.95,goal) of 10 µg/dL
was used as the target criterion (USEPA 2017c).The risk-based CAL of 6 mg/L for
adolescent recreators was multiplied by 10 to account for a 10-fold dilution of lead in
groundwater entering surface water; the final risk-based surface water CAL for the
adolescent recreator is 65 mg/L.
E.3.2 IEUBK Model
A site-specific risk-based CAL of 26 mg/L for lead in groundwater for adolescent
recreators was calculated using the IEUBK model (USEPA 2010). Default IEUBK
parameter values (USEPA 2010) were used for all parameters except those discussed
below.
A central tendency water ingestion rate of 0.05 L/day was used (USEPA, 2011). The
exposure frequency was 1 day/week.
IEUBK default model values for average ingestion of lead in the diet are shown in Table
E-3 below. These values were based on average lead concentrations measured in foods
collected as part of the U.S. Food and Drug Administration (FDA) Total Diet Studies
between the end of 1986 and the end of 1987 (USEPA 1994a). There is evidence that
dietary lead intake in the U.S. has fallen markedly since the late 1980s. USEPA Region 8
has used more recent dietary lead data from the Total Diet Studies reported by Gunderson
(1995) and Bolger et al. (1996) to develop modified dietary intakes (Table E-3) that were
used in the risk assessment for the Sandy, Utah site (Griffin 1997). These updated
dietary lead intake values have also been used to evaluate risk to human health from lead
4
in soil at the Douglas, Bisbee, and Orphan Mine sites in Arizona and the Malmstrom
AFB and Walkerville Residential sites in Montana. The updated values for dietary lead
intake recommended by USEPA Region 8 were used in the IEUBK model for calculating
the risk-based CAL for adolescent recreators.

For IEUBK model calculations, ingestion of lead in surface water at the Site was
accounted for by inputting the time-weighted average daily lead intake into the “Alternate
Source Intake” menu. The time-weighted average daily lead intake is based on the
following equation:

Derivation of the time-weighted average daily lead intake value of 20 µg/day was
iterative, that is, time-weighted average daily lead intake values were input into the
Alternate Lead Intake menu of the IEUBK model until the desired blood lead distribution
was achieved. The IEUBK model predicted that adolescent recreators with (1) a time-
weighted average daily lead intake of 20 µg/day from exposure to lead in surface water at
the Site and (2) exposure to background levels of lead in soil (at the home), drinking
water, diet, and air would have an approximate 5% probability of exceeding the 10 µg/dL
blood lead level of concern (see Attachment E.1, IEUBK Model Output).
A CALsw of 28 mg/L was back calculated using Equation 5.

A dilution factor of 10 was used to account for a 10-fold dilution of lead in groundwater
entering surface water.
E.4 Uncertainty in Calculating Risk-Based CALs for Lead
Uncertainties in the assumptions used to derive the CALs could result in an
overestimation or underestimation of the CALs for lead. However, conservative (health
protective) assumptions were used in the ALM and IEUBK model so as not to
overestimate the CALs. Therefore, the risk-based CALs for lead are protective of human
health despite the inherent uncertainties in the process.
E.4.1 Risk-Based CALs for Construction Workers
The risk-based CAL of 18 mg/L for construction/utility workers was calculated using
standard USEPA methodology for evaluating adult exposures to lead (USEPA 2017a).
6
Therefore, the CAL of 18 mg/L is protective of potential exposure of construction/utility
workers to groundwater in a trench. However, it is unlikely that construction/utility
workers at the Site will have significant direct exposure to groundwater in a trench due to
Occupational Safety and Health Administration (OSHA) requirements and the common
practice of eliminating the accumulation of groundwater in a trench in which workers are
present.
E.4.2 Risk-Based CALs for Adolescent Recreators
USEPA does not have a lead model for evaluating risk to adolescents. Therefore, risk-
based CALs for adolescent recreators of 65 and 28 mg/L were calculated using the ALM
and IEUBK model, respectively. There is uncertainty in using (1) a model protective of
adults and fetuses and (2) a model protective of young children (0-6 years of age) to
derive CALs for adolescent recreators, 7-18 years of age. However, conservative
assumptions were used in the ALM and IEUBK model that may overestimate blood lead
levels in adolescent recreators.
E.4.2.1 ALM
The EFw of 1 day/week used in the ALM to calculate the risk-based CALs of 28 mg/L
represents a higher rate of exposure than 2 days/month for 5 months for adolescent
recreators. The use of a higher EF in the ALM may have contributed to an overestimation
of blood lead levels in adolescent recreators.
USEPA (2017b) updated the PbB0 and GSDi parameters for the ALM model based on
2009 to 2014 National Health and Nutrition Examination Survey (NHANES) PbB data
using PbB data for U.S. women ages 17 to 45 years.
USEPA (2017d) reported that empirical data on BKSF appear similar for young children
and adults, but that uncertainty arises when applying a similar estimate for adolescence
(Mahaffey et al., 1998). The use of a BKSF for adults in the ALM may have contributed
to an overestimation or underestimation of blood lead levels in adolescent recreators.
E.4.2.2 IEUBK Model
The EFw of 1 day/week used to calculate the risk-based CAL of 28 mg/L represents a
higher rate of exposure than 2 days/month for 5 months for adolescent recreators. The
use of a higher EF in the IEUBK may have contributed to an overestimation of blood lead
levels in adolescent recreators.
The IEUBK default value for lead in background (residential) soil of 200 mg/kg (USEPA
2010) was used in the calculation of the risk-based CAL for adolescent recreators. The
default 200 mg/kg concentration of lead in residential soil is based on the high-end of a
plausible background range of 75-200 mg/kg for lead in soil and dust in urban areas
(USEPA 1994b). The 200 mg/kg concentration used in the IEUBK model to calculate
the risk-based CAL for adolescent recreators may overestimate soil lead concentrations at
off-site residences in the vicinity of the Site. For example, the 95% upper tolerance limit
(UTL) background concentration of lead in soil at the Site is only 16.6 mg/kg. The
7
assumption that lead is present in residential soil at a concentration of 200 mg/kg may
have contributed to an overestimation of blood lead levels in adolescent recreators.
The uptake of lead in soil (30%), drinking water (50%), surface water (50%), and the diet
(50%) for young children (0-6 years of age) assumed in the IEUBK model is higher than
typically reported for older receptors. For example, uptake of lead in soil in adults is only
12% (USEPA 2003a) and uptake of soluble lead in drinking water in non-fasted adults is
reported to range from 20 to 25% (USEPA 2003a). However, USEPA (2017d) reported
that the lead uptake may be higher in adolescents than in adults. The lead uptake rates
based on young children used in the IEUBK model to derive the risk-based CAL are
likely protective of lead uptake by adolescent recreators.
Adolescent recreators (7-18 years of age) would likely take in more air, drinking water,
and food than assumed in the IEUBK model for young children (0-6 years of age).
However, adolescent recreators would also have higher body weights and blood volume
than young children. Therefore, the use of intake values for air, drinking water, and food
based on young children (0-6 years of age) probably did not significantly impact the
calculation of the risk-based CAL for adolescent recreators.
USEPA (2017b) recommends updating the mother’s PbB concentration at childbirth from
1 µg/dL to 0.6 µg/dL in the IEUBK model based on 2009 to 2014 NHANES survey data.
The Technical Working Group reports that PbB concentrations continue to decline in the
U.S. population; the statistical approach for addressing non-detects was updated to reduce
the level of uncertainty associated with estimating PbB0, GSD, and maternal PbB. Lower
detection limits and lower rates of non-detects removed a “considerable source of
uncertainty” that was present in previous estimates of the geometric mean (USEPA,
2017b).
USEPA (2017d) reported that empirical data on BKSF appear similar for young children
and adults, but that uncertainty arises when applying a similar estimate for adolescence
(Mahaffey et al. 1998). The use of a BKSF for young children in the IEUBK model may
have contributed to an overestimation or underestimation of blood lead levels in
adolescent recreators.

E.5 Conclusions
Site-specific risk-based CALs were calculated that are protective of construction/utility
workers and adolescent recreators exposed to lead from groundwater at the Site. A risk-
based CAL for lead in groundwater of 18 mg/L for construction/utility workers was
calculated using the USEPA’s ALM. Risk-based CALs for lead in groundwater-to-
surface water of 65 and 28 mg/L for adolescent recreators were calculated using the
USEPA’s ALM and IEUBK model, respectively. The CAL of 65 mg/L is protective for
older adolescent recreators while the CAL of 28 mg/L is protective of adolescent
recreators of all ages (7-18 years of age).
8
Although there is uncertainty in some of the assumptions used to calculate the risk-based
CALs, the CALs are protective for construction/utility worker and adolescent recreator
scenarios due to the high conservatism of the assumptions.
