Memorandum

To: WMG&CP Group

From: Hany Debye, Jim Langseth, Colin Brownlow, and Julie Sullivan

Subject: Revised Soil Cleanup levels

Date: December 5, 2003

Project: 13/49-015 JSL 006

Executive Summary

This Technical Memorandum has been prepared for the purpose of: (1) updating the soil cleanup levels

for the Waukegan Manufactured Gas and Coke Plant (WMG&CP) Site (Site); and (2) evaluating

additional soil management options protective of mixed use redevelopment that could include future

residential land use at the Site.

The updated soil cleanup levels are summarized in Table 1. Two cleanup levels changed as a result of the

evaluations presented in this memorandum: the naphthalene cleanup level was lowered from

48,556 mg/kg to 2,240 mg/kg and the arsenic cleanup level was lowered from 940 mg/kg to 639 mg/kg.

All other cleanup levels are unchanged, and in fact were found to be more protective than previously

estimated.

The analysis presented in this memorandum, using current risk factors, shows that the revised ROD

cleanup levels incorporated herein, when combined with reasonable soil management options, are

protective for residential development as part of a mixed use redevelopment of the site. The soil

management options include: (1) reliable, effective vapor intrusion controls as part of building

construction standards; (2) the placement of at least 3 feet of clean fill on top of areas of the Site where

the redevelopment does not include buildings or other direct exposure barriers; and (3) adherence to the

provisions of the Soil Management Plan including groundwater use prohibitions and management of

excavated soil.

1.0 Introduction

This Technical Memorandum has been prepared to (1 ) update the soil cleanup levels for the Site: and

i'2'i provide the nsk analytical basis to evaluate alternative furure mixed use redevelopment options for the

Site, including residential land u&e This Technical Memorandum is based on the Record of Decision

HOD.i sod cleanup level development presented m the Feasibility Study (FS) for the Site (Barr. 1998).

The C:ry of Waukegan acquired the WMG&CP property after issuance of the ROD The City has

indicated a desire to be able to pursue mixed use redevelopment of the property. Based on discussions

with the City, die future mixed use redevelopment scenarios considered herein assume dial a minimum of

3 feet of clean fill will be placed on top of areas of the Site where no buildings or other direct soil

exposure barriers are constructed and where residual impacts may remain after completion of rhe soil

remedial action, and dial residential construction standards will include vapor intrusion control systems of

a minimum 95 percent control efficiency.

The revised sod cleanup levels account for adjustments in toxiciry information and risk calculation

procedures since the time of preparation of the FS. These adjustments are primarily related to the

avadabiliry of an inhalation toxiciry value for naphthalene, and a noncarcinogenic reference value for

arsenic but odier adjustments are also made, including an updated cancer slope factor for porychlorinated

biphenyls fPCBs) and updated toxicity values for naphthalene and dibenzofuran. This Technical

Memorandum evaluates naphthalene and benzene volatilization from die soil and eroundwater. for botii

indoor and outdoor exposure scenarios The methodology used in dus update is based on state-of-the art

science, policy and procedures defined in the United States Environmental Protection Agency (U.S. EPA)

exposure and nsk assessment guidelines and recommendations of expert Federal panels.

This Technical Memorandum summarizes the overall approach to developing target sod concentrations

and presents die updated cleanup level evaluation for commercial industrial land use. This Technical

Memorandum also evaluates additional soil management options to support potential mixed

redevelopment involving residential as well as commercial, recreational and other compatible land uses.

The Site ovvner or future developers will be able to use that evaluation as a basis to define development

options dial will preclude unacceptable nsk exposure and to define the required administrative steps to

obtain approval for alternative site redevelopment options

2.0 Target Soil Concentration Development Approach

Tzirget Soil Concentrations (TSCs) were developed using models identical to those used in standard U.S.

EPA risk assessments. However, with the TSC approach, an acceptable level of risk was predetermined,

and the corresponding acceptable target concentrations of the chemicals of concern (COCs) were

calculated for site-specific exposure scenarios. The risk levels presented are representative high exposure

(RHE) scenarios. These were the basis for the ROD soil cleanup levels. The risk levels are set at an excess

cancer risk of 10"5 for carcinogens for commercial/industrial and construction/utility scenarios, 10"6 for

carcinogens for the recreational-child scenario, and a hazard Index (HI) of 1 for noncarcinogens.

The overall approach used in the development of risk-based cleanup goals consisted of the following

steps:

1. Definition of future site use

2. Selection of COCs

3. Definition of exposure conditions

4. Toxicity assessment

5. Development of target concentrations for soil cleanup

The calculated TSCs for each exposure scenario are summarized in Table 2.

2.1 Guidance Documents

The TSCs for protection of human health were derived through use of standard risk equations and default

assumptions or a combination of default and site-specific assumptions as presented in the following U.S.

3.0 ROD Remedy Land Uses

This section updates the soil cleanup standards thai were selected in the ROD. and were originally

calculated in Appendix 3-B of the FS FS Appendix 3-B is reproduced in Appendix A of this

Memorandum for convenient reference For those scenarios used to calculate ROD soil cleanup levels, the

exposure assumptions for the original exposure scenarios are unchanged, the only adjustments are for

updated toxiciry information. For those scenarios that were not available from .Appendix 3-B of the FS.

new site-specific exposure assumptions are developed consistent with those used for the ROD soil

ciear.up !e\els Indoor vapor inhalation and recreational scenarios have also been added, for which new

exposure assumptions were added

3.1 COCs

The ROD selected the primary COCs in soil for the site: carcinogenic porynuclear aromatic hydrocarbons

i cPAHsV arsenic, dibenzofuran. 4-methylphenoL and naphthalene. The TSC calculations also consider

the COCs identified in the Human Health Risk .Assessment (HHRA. U.S. EPA, I995a) completed for this

site PCSs and benzene

3.2 Exposure Conditions

TSCs are developed based on the extent to which an individual would be likely to come into contact with

the COCs de:ected in sods i i e . the potential for exposure) The exposure assumptions used to develop

TSCs for the site were formulated through consideration of the site future land use. potential human

receptors, potentially complete exposure pathways, and exposure routes

Considerable judgment is in\oUed in the development of exposure conditions. In developing the TSCs,

conditions representing a high level of exposure to COCs at the redeveloped site were selected,

designated "representanve high exposure" ("RHE) The significant distinctions between RHE exposure

conditions and common'% used exposure conditions for development of preliminary remediation goals

?RGs. are highlighted in the following paragraphs Each of these exposure scenarios includes a

ccsbir-atien of default U S EPA \alues for nsk assessment as well as site-specific values.

3.3 Exposure Pathways

An exposure pathway consists of a contaminated source (e.g., soil), a point of potential contact for

humans with the contaminated source, and an exposure route (e.g., ingestion of contaminated soil). The

following paragraphs describe applicable pathways and site-specific conditions.

Soil Pathway. Based on commercial/industrial future land use, the potential for direct human contact with

site soils was assumed to be a viable exposure pathway. It was assumed that the potential human

receptors may ingest or come hi contact with soils as a result of the following activities:

1. Exposure of construction/utility workers to surface and subsurface (upper 5 feet) soils.

2. Occupational exposure to surface soils at the redeveloped site during normal

commercial/industrial land-use activities.

ITie ROD remedy provides for removal of soil with a 1 x 10"5 or higher excess cancer risk or HI greater

than 1. Soil with an excess cancer risk between 1 x 10"5 and 1 x 10"6 is to be covered with a 6-inch soil

cover, buildings, parking surfaces, or other direct-contact barriers.

ITie ROD remedy is also consistent with recreational land use for the site. For recreational land use, it is

assumed that 6 inches of soil cover would be placed over the entire site. Consequently, recreational users

axe not subject to direct contact exposures, but the vapor inhalation pathway must still be considered.

Table 3 is a summary of the soil cover program according to land use.

Air Pathway - Contaminants in surface soils could be released to the ambient air through volatilization

and wind-driven erosion or mechanical suspension. Contaminants hi subsurface vadose zone soils could

be released to the ambient air through volatilization. The significance of the ambient air inhalation

pathway depends on site conditions such as the human behavior patterns, the physical and chemical

characteristics of the contaminants, the degree of soil disturbance, the soil chemical concentrations,

meteorological conditions, soil moisture, and related soil properties. Reference concentrations for chronic

exposure to naphthalene vapors have become available since the time the FS was in preparation.

Consequently, this Technical Memorandum includes evaluation of the air pathway in developing the

TSCs for the construction/utility, the commercial/industrial scenarios, and the recreational-child scenario.

The commercial/industrial evaluation also considers volatilization of naphthalene and benzene from the

soil or groundwater to indoor air space.

3.4 Exposure Routes

An exposure route is how a particular COC connects to a receptor. In the development of TSCs. it was

assumed that construction utility and commercial industrial workers could be exposed to COCs in soil by

two primary exposure routes incidental sod ingestion. and inhalation of particulates and volatiles

released from soils. While exposure through dermal contact is also possible, this exposure route was not

quantitatively evaluated due to the lack of dermal toxicity values. The absorption of chemicals from soil

depends on chemical-specific factors as well as the characteristics of the soil. For chemicals exhibiting

percentage absorption from soils less man 10" a, (such as the COCs for this site) the dermal pathway is not

expected to be significant in comparison to the soil ingestion and inhalation exposure pathways. For the

rtcreanonal-child scenario, it was assumed that a child playing outdoors could be exposed to COCs by

irJialanon of volatiles released from soils

For this evaluation, the TSCs based on the soil ingestion and or inhalation exposure routes (whichever is

lower) are considered protective for the dermal exposure route as well. In the HHRA, the dermal exposure

was assumed to be equivalent to exposure from ingestion in accordance with IEPA guidance at that time.

This approach may have resulted in an overestimanon of nsk. It should be noted that the dermal exposure

route is not included in the US EPA Soil Screening Guidance for Chemicals (U.S. EPA, 2003a)

calculation model In developing the PRGs m the HHRA the U.S. EPA used the same exposure routes for

all COCs except for cPAHs and PCBs. For these compounds, the HHRA did not consider inhalation

exposure due to a lack of inhalation toxicity values In developing the TSCs. inhalation and ingestion of

these contaminants is treated in the same manner as in the HHRA. The specifics of the exposure scenarios

are summarized below and in Table 4

3.5 Exposure Scenarios

1. Construction/Utility Wofkef

This site-specific exposure scenario is from FS Appendix 3-B (attached as Appendix A to this

memorandum) and was used in development of the soil cleanup levels adopted in the ROD. It

was assumed dial a construction worker would be exposed to the upper 5 feet of contaminated

sod ^the entire depth of the vadose zone) over an exposure domain of approximately 2 to 5 acres.

This corresponds to construction of a foundation for a structure the size of OMC's Plant No. 1

south of the Site. An exposure frequency of 30 days was considered representative of the

duration a given worker might be constructing foundations for such a building. For the utility-

worker exposure scenario, it was assumed that a utility worker would be exposed to the upper

5 feet of contaminated soil over an exposure domain of approximately 2 acres. This corresponds

to one utility construction crew building three utility lines (storm sewer, sanitary sewer, and

water) along the entire north-south dimension of the site. An exposure frequency of 30 days to

perform the work was considered a reasonable estimate. To obtain an RHE, the exposure

frequency was considered to be 60 days for the construction or utility worker, based on the above

estimates, and an allowance of a factor of 2 for uncertainty in work efficiency. A soil ingestion

rate of 200 mg/day was used for calculation of the risk associated with the ingestion pathway, and

is considered a high ingestion rate based on the nature of most utility and foundation construction

work. In addition to exposure via ingestion, there is the potential for inhalation exposure from

dust and volatile compounds, which was also evaluated for the construction/utility worker

scenario.

2. Commercial/Industrial Worker

This site-specific exposure scenario is from FS Appendix 3-B (attached as Appendix A to this

memorandum) and was used in development of the soil cleanup levels adopted in the ROD. To

develop a basis for potential occupational exposure under the commercial/industrial scenario, it

was assumed that the exposure domain would be on the order of 5 acres. For the RHE scenario, it

was assumed that workers may be outdoors for lunch or other activities for 97.5 days/year (the

estimated number of decent weather, non-vacation days per year) over a 25-year period. The

exposure pathways evaluated for the commercial/industrial worker scenario were inhalation

exposures from dust and volatile compounds and exposure via ingestion (see Appendix B).

Incidental ingestion was assumed to be 2 milligrams of contaminated soil per day to reflect the

time spent outdoors in proportion to time spent indoors. The RHE exposure scenarios represent a

high level of exposure, considering likely site-specific future conditions. For most compounds,

the exposure conditions which have the greatest sensitivity with regard to future risk are the

assumed ingestion rate, exposure frequency and the volatilization of contaminants. The ingestion

rate of 2 mg/day and the exposure duration of 97.5 days/yr represent upper bound values for

future exposure scenarios when considering the likely outdoor activities for future

industrial/commercial workers and the likely limited exposure to bare soil surfaces. The ROD

remedy provides for removal of the soil that exceeds a 1 x 10~5 excess cancer risk or hazard index

of 1 under this scenario. Soil between 1 x 10"5 and 1 x 10"6 excess cancer risk is covered with

6 inches of soil and vegetation, gravel, asphalt or concrete and buildings in accordance with the

ROD remedy. Consequently, the ROD remedy, including soil cover would, for practical

purposes, preclude the exposure pathway and be much more protective than indicated by the soil

cleanup levels used to define soil remo\'a]. Most new industrial commercial facilities incorporate

significant pavement and Landscaping, and most commercial'industnal workers spend the

majority of the working day indoors Realistically, after the ROD remedy, and certainly after

redevelopment, it is likely that there will be no opportunity for these workers to contact

subsurface soils

IE addition to outdoor exposure, there is the potential for inhalation exposure to volatile

compounds (i.e., naphthalene and benzene) that may enter the building through cracks in the

foundation The indoor exposure evaluation was performed in order to assess the concentration of

naphthalene or benzene in the soil or groundw arsr that would be protective in the absence of

building vapor control measures The evaluation used the Johnson and Eningei Soil Vapor

Intrusion Model, and incorporates default values as needed from tbe document User's Guide for

Evaluating Subsurface Vapor Intrusion into Buildings (U.S. EPA. 2003b). Some of the key-

inputs are site-specific values - where default values may be inappropriate. The modeling

assumed the ROD remedy 6-inch soil cover was present, except below the slab-on-grade

construction as shown on Figure 1 . Tbe 6-inch cover matches the slab thickness assumed in the

model, so in order to maintain internal consistency in tbe model, the 6-inch cover was assumed to

be the same soil as the current vadose zone at the site. In actual practice, the cover soil can be

whatever is most suitable for redevelopment Figure 1 shows the soil profile and soil parameters

used in the model There was no reasonable high exposure scenario developed for this exposure

route at the time of FS preparation The RHE conditions for this scenario assumed mat a given

commercial'industnal worker would be exposed for an average of 25 years for 219 days per year.

The basis for this scenario is developed in greater detail in Appendix B. This RHE scenario is a

higher exposure level than would be used for seasonal marine commercial activity such as that

typical of the existing Larsen Marine business Appendix B also includes copies of the

spreadsheets mat were used in the modeling

The building ventilation parameters used in the modeling were tbose recommended for standard

construction. The air in commercial space was assumed to exchange 1 .5 times per hour, which is

based on the ASHRAE 62-1999 (ASHRAE is the American Society of Heating Refrigerating and

Air-Conditioning Engineers) standard for commercial office space, assuming 12-foot ceilings.

The \^lues used in the model are consistent with new construction No vapor barrier was

assumed in this modeling. Note that space with less ventilation than assumed may compensate

with addition of vapor control.

The Johnson and Ettinger model uses an inherently conservative approach to estimating indoor

air concentration of vapors. The model assumes the entire area under the building is at the

estimated concentration of the compound. The vapor intrusion to the building assumes soil vapor

can readily enter the building, predominantly through cracks along the foundation perimeter. The

model is designed to be reliably conservative, and has been structured and designed to over-

predict indoor concentrations as compared to actual conditions.

3. Recreational - Child

For this scenario, which was not considered in FS Appendix 3B, it was assumed that a child

would be playing outdoors in a "sandbox" all day 20 days per year over a 6-year period. The

TSCs developed (see Table 2) based on this exposure scenario are expected to be protective for

recreational use of the site where activities such as walking or picnicking could occur, as these

involve less intense exposure. An exposure frequency of 20 days was considered representative

of the number of times a given child might be playing in the area. The only potential exposure

pathway for the recreational-child exposure scenario would be the inhalation pathway. A child

would not be exposed to the COCs via direct contact with the soil, ingestion of the soil, or

inhalation of fugitive dust because the site will be covered (soil and vegetation, gravel, asphalt or

concrete and buildings), thus limiting exposure. The details of the modeling of this scenario are

in Appendix B.

3.6 Toxicity Assessment

The chemical concentration in soil that is considered safe depends, in part, on the inherent chemical

toxicity. The toxic effect of a chemical also depends on the dose or concentration of the substance to

which an individual is exposed. Toxicity values describe the quantitative dose-response relationship

between the chemical dose to which a receptor is exposed and the incidence of adverse health effects.

The toxicity value for a chemical may differ depending on the route by which a receptor is exposed (i.e.,

by ingestion, inhalation). Due to the lack of toxicity values for dermal exposure, this exposure route could

not be quantitatively evaluated. It should be noted that the dermal exposure route is not included in the

U.S. EPA Soil Screening Guidance for Chemicals (U.S. EPA, 2003a) calculation model as explained in

Section 3.4. The use of dose-response data from oral exposure for a specific chemical to predict effects

supported by scientific evidence Consequently, using the oral slope factor to evaluate the risk associated

wim dermal exposure to PAHs. which cause skin cancer through direct action at the point of application,

is no? appropriate For the cPAHs ai this Site, the dermal exposure route is likely to be a much less

significant contributor to nsk than the mgestion exposure route. The lowest concentration among the

various pathways was selected as die cleanup level for the site. Consequently, the absence of quantitative

evaJuanon of the dermal pathway introduces only a very small level of uncertainty in the cleanup level

oc process

3.6.1 Cancer Risk

The dose-response relationship for carcinogens is expressed as a cancer slope factor or unit risk factor.

Generally, the slope factor is a plausible upper -bound estimate of the probability of a response-per-unit

intake of a chemical over a lifetime The slope factor is usually, but not always, the upper 95th percentile

confidence limit of the slope of the dose-response curve and is expressed as the probability of a response

per milligram of chemical per kilogram of body weight per day (mg'kg-day)"- In risk assessment, the

slope factor is used to estimate an upper-bound lifetime probability of an individual developing cancer as

a result of exposure to a carcinogen A unit nsk factor is analogous to the slope factor but is expressed in

units of fug m*)'

3. 6.2 Nonc*ncw Risk

The dose-response relationship for noncanrinogens is expressed for ingestion as a reference dose (RfD) in

milligrams of chemical per kilogram of body weight per day (mgkg-day) or for inhalation as a reference

concentration (RfO expressed in milligrams per cubic meter of air fangm5). The reference dose

i reference concentration) represents the concentration of a contaminant dial is likely to be without an

appreciable nsk of adverse heal± effects during a lifetime daily exposure. In nsk assessment die RfD

CRfC) is used to estimate die potential for adverse health effects due to exposure to contaminants in soil or

air.

Toxicity values derived by U.S. EPA for noocancer effects were used to develop die TSCs. This update

uses die reference concentration (HfO for naphdiakne published by U.S. EPA in IRIS. This reference

concentration is appropriate for chronic exposures (i.e.. longer tian 7 years) only, so use of riis value for

shorter duration exposures (utility worker) is highly conservative. The RfC developed by rive U.S. EPA

was based on studies conducted widi laboratory mice because adequate human data were not available.

There is an extensive database showing that mice are more sensitive than humans and other primates (as

well as more sensitive than rats, the other common laboratory test animal) to the effect of naphthalene on

the respiratory tract. Because of the deficiencies in the database for naphthalene, the U.S. EPA lowered

the RfC by an extra factor of 3 (that is, rather than the typical uncertainty factor of 1000, an uncertainty

factor of 3000 was applied for naphthalene, indicating a high level of imprecision in the toxicity value).

The California Reference Exposure Level (REL = 0.009 mg/m3, CalEPA/OEHHA, 2003) and the ATSDR

Minimal Risk Level (MRL = 0.010 mg/m3, ATSDR, 1995) for naphthalene, which are the equivalent of

the IRIS value, are 3 or more times higher than the IRIS Reference Concentration (0.003 mg/m3).

Broadly, this means that the inhalation-based naphthalene TSCs presented here are likely 3 or more times

lower than may be justified by the available lexicological information about naphthalene.

3.7 Development of TSCs

The acceptable risk level for cancer and noncancer effects to determine site cleanup goals is primarily a

policy decision by the risk manager. A cancer target risk value of one-excess-cancer-in-one-hundred-

thousand (10"5) over background risk level was selected by U.S. EPA in the ROD for the cancer endpoint

for soil removal, and is used here in the development of the RHE TSCs. The recreational scenario uses a

one-in-one-million (10"6) excess cancer risk. For noncancer effects a hazard index of 1 was used (HI = 1)

for all scenarios.

To calculate the acceptable soil concentration for the inhalation pathway, a particulate emission factor

(PEF) and volatilization factor (VF) were derived based on guidance provided in U.S. EPA's Risk

Assessment Guidance for Superfund, Part B (U.S. EPA, 1991) and Soil Screening Guidance document

(U.S. EPA, 1996).

To calculate the TSCs, the exposure conditions are combined with the toxicity/cancer risk data for each of

the COCs. Using these exposure values and the chemical-specific toxicity/cancer risk values, the target

soil concentrations were calculated. Appendix B presents the calculation of the target soil concentrations

for protection of human health. The resulting TSCs for the various exposure pathways are summarized in

Table 5. The lowest TSC for each exposure scenario was selected as the cleanup level. The cleanup levels

are summarized in Table 1. The cleanup levels for cPAHs increased as compared to the ROD levels. No

adjustment of the ROD levels is proposed as a result of these updated TSC calculations. However, these

results do show that the ROD cleanup levels for cPAHs are more protective than the nominal threshold of

10"5. The arsenic cleanup level decreased to 639 mg/kg, the value shown for the ingestion pathway,

noncarcmogenic. for the construcaon utility scenano The naphthalene cleanup level decreases to

2.240 mgkg. the value shown on Table 5 for the commercial industrial vapor intrusion exposure scenario.

The naphthalene cleanup level is greater than the nominal soil saniranon level for naphthalene. At the

site, naphthalene is a separate component solid at ambient temperatures (melting point 80°C), or is

present as a component of coai tar The US EPA Region 9 memorandum describing use of their

Preliminary Remediation Goals (PRGs i fl'.S EPA 2002 ) explains that for substances that exceed the soil

saruranon limit and are solids, the PRO should not be calculated based on the inhalation pathway. The

Soil Screening Guidance (U S EPA. 1996) suggests the cleanup level for such chemicals should be based

on protection of other exposure pathways in such cases In view of the much higher cleanup levels that

are calculated for naphthalene based on the other pathways, the conservatism associated with using this

vapor intrusion calculation approach was accepted for selection of the ale-specific naphthalene cleanup

level

A cancer target nsk value of one excess cancer-in-one-million ( 'ICT^i over background risk level was

selected for the cancer endpoint in the development of the recreanonal-child TSCs. For noncancer effects

a HI of 1 was used The naphthalene TSC for the recreanonal-child scenario is 24.000 mgfcg, as shown in

Tables 2 and 5. This is a higher standard than the commercial industrial naphthalene TSC. Consequently

the ROD cleanup, with the rev.sed 2.240 mglg naphthalene cleanup value is also protective of the

rtcrcanonal scenario Sunilarh . the Table 2 benzene TSC for the recreational-child scenario is

540 rnglcg, which is a higher value than the commercial industrial TSC of 5.5 mgltg, and higher than any

reponsd vadose zone soil concentration of benzene at the Site. Consequently, the ROD cleanup is also

proiecnve of the recreational scenano

The volatilization from groundwater model results are included in Appendix B There is no reason to

expect an indoor air problem from groundwater. The highest reported shallow groundwater sample

naphthalene concentration at the Site was 2.400 ugl. which is much less than the acceptable

concentrations derived from commercial industrial vapor intrusion model (79.700 jig-L. a value which

exceeds die 31.200 ug/L solubility of naphthalene). The highest reported shallow groundwater sample

benzene concentration at the Site was 70 ugL. which is much less than the acceptable concentrations

derived from commercial industrial vapor intrusion model (4.930 ug.L).

The vaporization from soil model shows that for commercial industrial space, there is no reason to expect

an indoor air problem with respect to naphthalene. The revised soil naphthalene cleanup standard of

2,240 mg/kg is protective of workers, without a vapor intrusion control system. It assumes the standard

office space ventilation of 1.5 air exchanges per hour. Including a vapor intrusion control system

requirement in commercial/industrial building standards for Site redevelopment such as those required for

residential redevelopment would lower potential worker exposure further and would accommodate lower

building air exchange rates. The modeled benzene concentration of 5.5 mg/kg is shown in Tables 2 and 5

and Appendix B, and is the lowest of the benzene concentrations protective of construction/utility and

commercial/industrial workers. This protective concentration assumes no vapor intrusion control system.

Benzene concentrations of interest at the Site are found in association with tar, and the tar cleanup levels

are much more rigorous than this benzene value. Consequently, no separate benzene cleanup level is

proposed for the site remedy.

4.0 Mixed Use Development

llu's portion of the Technical Memorandum evaluates additional soil management options for potential

mixed use redevelopment involving residential as well as commercial, recreational, and other compatible

land uses. TSCs protective of commercial/industrial and recreational land use scenarios were developed

above. This section evaluates additional soil management options to support the development of mixed

use redevelopment plans that could include potential future residential land use at the property. As noted

below, the revised ROD cleanup standards incorporated herein when combined with vapor intrusion

controls as part of building construction standards and the placement of at least 3 feet of clean fill on top

of areas of the Site where the redevelopment does not include buildings or other direct exposure barriers,

!ind where residual impacts may remain after completion of the soil remedial action, will allow residential

sis well as commercial and recreational redevelopment based on current risk factors. These provisions will

be identified in the Soil Management Plan (SMP) to be developed for the site.

The SMP will enumerate other requirements for redevelopment of the site as well. These include a

groundwater use prohibition, a program for management of excavated soil, soil sample data that can be

used for development of OSHA worker "right-to-know" information, as necessary, and other information

and guidance to accommodate work at the site or changes to the land use at the site.

Among the additional soil management options available to support potential residential development at

this former industrial property, there are two that directly affect the risk evaluation: (1) placement of at

least 3 feet of clean soil cover over the areas of the Site where the redevelopment does not include

buildings or other direct soil exposure barriers (e.g., paved surfaces, landscaping above current grade,

sidewalks, and other amenities) and where residual impacts may remain after completion of the soil

remedial action; and (2) installation of \apor control systems when buildings are constructed. These

requirements are consistent with City expectations. The City of Waukegan has stated, in their August 21,

2003 Technical Memorandum "Revised Risk Assessment Evaluation." that engineering controls such as

installing vapor control systems en future buildings can be used to eliminate the indoor vapor intrusion

pathway. The City document also called for a minimum of 36 inches of clean soil cover to be added to

areas that will not be subject to other exposure controls

The addition of 3 feet of clean cover soil eliminates any credible exposure pathw-ay for routine oral or

derma] contact with any residual soil contamination The installation of vapor control systems on

builings provides a system for addressing any future vapor intrusion issues

4.1 COCs and Toxic fty Assessment

The COCs for the Site were identified above for the commercial industrial and recreational scenarios, and

appry to the residential scenario as well. The toxjcity assessment summarized above for the

commercial industrial and recreational scenarios also covers the matters relevant to the residential

scenario

4.2 Exposure

Most of the site will be covered (soil and vegetation. gravel. asphalt or concrete and buildings), thus

limiting exposure to only inhalation of chemicals in air due to volatilization The recreational scenario

presented earlier provides confidence that the ROD remedy, with the naphthalene adjustment proposed in

this Technical Memorandum, is protective for outdoor recreational and residential activities.

Indoor A:r Exposure -The indoor exposure evaluation was performed in order to assess the concentration

of naphthalene or benzene in soil or groundwater thai would be protective, assuming building vapor

control measures as called for in the City's Revised Risk Assessment Evaluation. The evaluation here is

based on vapor controls thai are 95 percent efficient (i e . intercept or block 95 percent of the subsurface

vapor from entering the indoor air space) The soil and groundwater concentrations were developed by

applying this 95 percent efficiency to the concentrations from the Johnson and Ettinger Soil Vapor

Intrusion Models in Appendix C. The models incorporate default values as needed from the User's Guide

for Evaluating Subsurface Vapor Intrusion into Buildings and site specific values where default values

may be inappropriate.

The model default values assume a one story structure with approximately 1,000 square feet of living

space, occupied continuously 350 days per year. This is not consistent with new urban development.

Accordingly, the exposure assumptions were adjusted to reflect at least a modest amount of time spent

away from the residence, whether at work, running errands, vacationing, or for other activities. The

exposure frequency was set at 208 days per year, with an exposure duration of 9 years. The basis for this

scenario is developed in greater detail in Appendix C. No correction was applied to account for multi-

story buildings typical of new urban development. The building ventilation parameters used in the

modeling were those recommended in ASHRAE 62-1999 for residential construction: the air in

residential structures was assumed to exchange 0.35 times per hour (rather than the default value of 0.25

exchanges per hour).

The modeling (see Appendix C) assumed the ROD remedy 6-inch soil cover immediately adjacent to the

building and slab-on-grade construction. The 6-inch cover matches the slab thickness assumed in the

model, so in order to maintain internal consistency in the model, the 6-inch cover was assumed to be the

same soil as the current vadose zone at the site. In actual practice, the cover soil may be whatever soil

types are most suitable for redevelopment, and would be a more protective 3-feet thick rather than

6 inches thick. Figure 1 shows the soil profile and soil parameters used in the model.

4.3 Development of TSCs

The vapor intrusion to indoor air pathway was considered for both vaporization from groundwater and

from soil. The model of vapor intrusion from soil for residential space, with a 95 percent efficient vapor

control system in place, shows that the revised ROD soil cleanup levels (Table 1) are protective.

The model result for vapor intrusion from soil for benzene, with a 95 percent efficient vapor control

system, is 2.4 mg/kg as shown in Table 5. This concentration exceeds any Site vadose zone soil benzene

concentration reported outside the ROD remedy soil removal area.

The vaporization from groundwater model, also applying the 95 percent efficient vapor control system,

shows that naphthalene is not a parameter of concern for residential land use. The modeled groundwater

concentration exceeds the solubility of naphthalene. This was the case even in the absence of

supplementary vapor control systems.

The vaporization from groundwater model for benzene also shows that a 95 percent efficient vapor

control system is protective for residential buildings. The highest reported shallow groundwater sample

benzene concentration at the Sue ( "0 ugL) was less than the Table 5 concentration derived from the

residential vapor intrusion model i 12.000 uglA The model shows that the shallow groundwater benzene

concentrations at the Site would not be a problem even in the absence of supplement^ vapor control

The vapor intrusion modeling has implicit avsragmg over a domain equal to the size of the structure. In

fact, ihc siir soil cleanup levels are maximums. so the actual average residual concentrations in the soil

%v-J be lower than the cleanup levels. Thus, measures to provide protection at the stated level will actually

afford a margin of security beyond the nominal protective level.

The conclusion of this review of the potential for mixed use redevelopment of the site is thai the ROD

cleanup le%els are protective, with naphthalene meeting the revised cleanup levels suggested in this

Technical Memorandum, and incorporating the City's requirements for buildings of a vapor control

system tha: is reliably 95 percent efficient, and where there will be no buildings or other exposure

barriers, the addition of 3 feet of soil cover

Development of Target Soil ConcentrationsProtection of Human Health

The target soil concentrations (TSC) for protection of human health were derived through use of

sl^ndard risk equations and default assumptions or a combination of default and site-specific

assumptions as presented in the following EPA guidance documents:

• Risk Assessment Guidance for Superfund: Volume I - Human Health Evaluation Manual

Pan A, 1989

• Risk Assessment Guidance for Superfund: Volume I - Human Health Evaluation Manual

Part B, Development of Risk-Based Preliminary Remediation Goals, 1991

• Soil Screening Guidance: Technical Background Document, 1996

• Exposure Factors Handbook, 1989, 1996

• Dermal Exposure Assessment: Principles and Applications, 1992

TSC Approach

TSCs were developed using models identical to those used in standard EPA risk assessments.

However, with the TSC approach, an acceptable level of risk (i.e., 10"4, 10"5, 10"6) was predetermined,

and the corresponding acceptable target concentrations of the chemicals of concern were calculated

for site-specific exposure scenarios for the site.

The overall approach used in the development of risk-based cleanup goals consisted of the following

steps:

1. Selection of target chemicals

2. Definition of future site use

3. Definition of exposure conditions

4. Toxicity assessment

5. Development of target concentrations for the preliminary remediation goals

201481 3-B-l

Target Chemicals •

Based on the HHRA completed for this site, the primary contaminants of concern in soil were

carcinogenic PAHs and arsenic (U.S. EPA, 1995a). The TSCs also consider the COCs identified for

the site in the HHRA—PCBs, benzene, dibenzofuran, 4-methylphenol, and naphthalene.

Future Site Use

Future site use is considered to be industrial and/or commercial. A detailed assessment of future

land use considerations is presented in Appendix 3-C.

Exposure Conditions

TSCs are developed based on the extent to which an individual would be likely to come into contact

with the target chemicals detected in soils (i.e., the potential for exposure). The exposure*

assumptions used to develop TSCs for the site were formulated through consideration of the site %•?

future land use, potential human receptors, potentially complete exposure pathways, and exposure

routes. *"

Considerable judgement is involved in the development of exposure conditions. In developing the

PRGs in the HHRA, two sets of exposure conditions—reasonable maximum exposure (RME) and

central tendency exposure (CTE)—were evaluated. In developing the TSCs, a new set of exposure

conditions is used—representative high exposure (RHE). The significant distinctions between these. i

exposure conditions are highlighted in the following paragraphs. Each of these exposure scenarios

includes a combination of default EPA values for risk assessment as well as site-specific values. **A

Exposure Pathways _

An exposure pathway consists of a contaminated source (i.e., soil), a point of potential contact for

humans with the contaminated source, and an exposure route (i.e., ingestion of contaminated soil). «*

The following paragraphs describe these pathways and site-specific conditions. ,,„

f»3

Soil Pathway—Based on the anticipated future land use, the potential for direct human contactN

with site soils was assumed to be a viable exposure pathway. It was assumed that the potential

human receptors may ingest or come in contact with soils as a result of the following activities: ^\M

1. Exposure of construction/utility workers to surface and subsurface (upper 5 feet) soils. *^

201481 3-B-2

2. Occupational exposure to surface soils at the redeveloped site during normal

commercial/industrial land-use activities.

Air Pathway—Contaminants in surface soils could be released to the ambient air through wind-

driven erosion or mechanical suspension. The significance of the ambient air inhalation pathway

depends on site conditions such as the human behavior patterns, the degree of soil disturbance, the

soil chemical concentrations, meteorological conditions, soil moisture, and related soil properties.

The air pathway was included in developing the TSCs for the construction/utility and

commercial/industrial land use activities.

Exposure Routes

In the development of TSCs, it was assumed that utility, construction, and commercial/industrial

workers could be exposed to target chemicals in soil by three exposure routes: incidental soil

ingestion, dermal contact with soils, and inhalation of particulates and volatiles released from soils.

In developing the PRGs in the HHRA, the U.S. EPA used all three exposure routes for all chemicals

of concern except for cPAHs and PCBs. For these compounds, the HHRA did not consider

inhalation exposure due to a lack of inhalation toxitity values. In addition, the dermal exposure

was assumed to be equivalent to exposure from ingestion in accordance with IEPA guidance. In

developing the TSCs, inhalation is treated in the same manner as the PRG calculations. However,

dermal contact exposure is considered separately from ingestion because new values for dermal

exposure are available in accordance with U.S. EPA guidance (U.S. EPA, 1998). The specifics of the

tiiree exposure scenarios are summarized below and in Table 3-B-l.

• Utility Worker

For the utility worker exposure scenario, it was assumed that a utility worker would be

exposed to the upper 5 feet of contaminated soil (the entire depth of the vadose zone) over

an exposure domain of approximately 2 acres. This corresponds to one utility construction

crew building three utility lines—storm sewer, sanitary sewer, and water lines—along the

entire north-south dimension of the site. The exposure frequency was considered to be from

8 to 15 days for the CTE and RME scenarios. For the RHE scenario, this was increased to

60 days based on an estimate of 30 days to perform the work, and an allowance of a factor

of 2 for uncertainty in work efficiency. The soil ingestion rate of 216 to 480 mg/day for the

CTE and RME exposure scenarios was reduced slightly to 200 mg/day for the RHE scenario

based on the mechanized nature of most utility construction work. Finally, for dermal

201481 3-B-3

contact, the CTE and RME exposures used a skin area of from 5.000 to 5.600 cm: with an

adherence factor ranging from 0.2 to i.O mg/on3. For the RHE exposure scenario, the value

of 5.800 on1 of exposed skin was retained as this is representative of the hands, arms and

head. However, die low value of 0.2 for adherence of soil to skin was used as this

represents an upper bound for irrigation installers.

• Construction Worker

For the construction worker, it was assumed that a construction worker would be exposed

to the upper 5 feet of contaminated soil over an exposure domain of approximately 2 to 5

acres. This corresponds to construction of a foundation for a structure the size of CMC's

Plant So. 1 south of the she. The exposure frequency used was from 16 to 21 days for the

CTE and RME scenarios. For RHE. the exposure frequency was increased to 30 days. Sou

ingestion and adherence values for the construction worker scenario were considered

equivalent to those used for the construction worker for RME. CTE, and RHE exposure

scenarios

• Commercial or Industrial Workers

To develop a basis for potential occupational exposure under the commeraallndustrial

scenario, it was assumed that the exposure domain would be on the order of 5 acres.

However, most of the site will be covered (soil and vegetation, gravel, asphalt or concrete

and buildings', thus Limiting exposure. For the RME and CTE scenarios, the exposure

frequency was assumed to be 165 days per year with the exposure duration varying from

9 to 25 years. For the RHE scenario, it was assumed that workers may be cutdoors for

lunch or other activities for 97.5 days/year (the estimated number of decent weather, non-

vacation days per year) over a 25-year period. Incidental ingestion was assumed to be from

0 825 to 8 05 grams of contaminated soil per day for CTE and RME, but was reduced to

0.002 for RHE in order to reflect the time spent outdoors in proportion to the total.

Similarly, the soil adherence factor ranged from 0.2 to 1.0 for CTE and RME. but was

reduced to .043 for RHE. The significantly lower values for RHE were used because it

better represents credible exposure values, as explained below. Realistically, after

redevelopment it is likely that there will be no opportunity for these workers to contact

subsurface soils.

2c:*5i 3-E-i

As previously mentioned, the RME and CTE values are typical of conservative preliminary

remediation goals, but may be overly conservative for evaluating potential remedial actions during

a feasibility study. By comparison, the target soil concentrations calculated using the RHE

exposure scenario represent appropriate level of risk for consideration of site-specific future

conditions. For most compounds, the exposure conditions which have the greatest sensitivity with

regard to future risk are the assumed ingestion rate, exposed skin area, the soil adherence factor,

and the exposure frequency. For example, the relatively high ingestion rates considered in the

RME and CTE scenarios for the utility/construction worker scenarios exceed the ingestion rate used

in the RHE scenario of 200 mg/day. This value is based on an tipper value for irrigation installers

and is therefore more representative of a reasonable upper bound for ingestion by utility/

construction workers.

Similarly, the ingestion rate, exposed skin area, and exposure frequency for the reasonable high

exposure scenario (2 mg/day, 840 cm2, and 97.5 days/yr) represent upper bound values for future

es:posure scenarios when considering the limited extent of likely outdoor activities for future

industrial/commercial workers and the likely limited exposure to bare soil surfaces. Most new

industrial/commercial facilities incorporate significant pavement and landscaping, and most

commercial/industrial workers spend the majority of the working day indoors. The soil adherence

factor, 0.043 mg/cm2, is based on soil adherence to the hands of greenhouse workers. Soil

adherence factors of 0.2 mg/cm2 and 1.0 mg/cm2 correspond respectively to irrigation installers

(hands only; arms, legs and face were 0.02 mg/cm2 or less) and a factor between reed gatherers

(hands) and the high-end amount for rugby players.

Toxicity Assessment

The chemical concentration in soil that is considered safe depends, in part, on the inherent

chemical toxicity. The toxic effect of a chemical also depends on the dose or concentration of the

substance to which an organism is exposed. Toxicity values describe the quantitative dose-response

relationship between the chemical dose to which an organism is exposed and the incidence of

adverse health effects. The toxicity value for a chemical may differ depending on the route by

which an organism is exposed (i.e., by ingestion, inhalation or through dermal contact).

201481 3-B-5

Cancer Risk

The dose-response relationship for carcinogens is expressed as a cancer slope factor or unit risk

factor. Generally, the slope factor is a plausible upper-bound estimate of the probability of a

response-per-unit intake of a chemical over a lifetime. The slope factor is usually, but not always,

the upper 95th percent confidence limit of the slope of the dose-response curve and is expressed as

the probability of a response per milligram of chemical per kilogram of body weight per day:.mg/kg-day)'1. In risk assessment, the slope factor is used to estimate an upper-bound lifetime

probability of an individual developing cancer as a result of exposure to a carcinogen. A unit risk

factor is analogous to the slope factor but is expressed in units of (ng/m*)"1.

Tcxicty values derived by EPA for carcinogenic effects were used to develop the TSCs.

Development of TSCs

Toe acceptable risk levels for ra.ncer and noncancer effects to determine site cleanup goals is a

policy decision, not a risk-based decision. The State of Illinois guidance provides a cancer target

risk value of one excess cancer-in-one-hiindred-thousand (10"s) over background risk level for the

cancer endpoint. This risk criterion was used in the development of the TSCs.

To calculate the acceptable soil concentration for the inhalation pathway, a parti en] ate emission

factor -PET) and volatilization factor <VF) were derived based on guidance provided in EPA's RAGS

part B and Soil Screening Guidance document.

To calculate the PRGs, the exposure conditions are combined with the toxidty/cancer risk data for

each of the chemicals of concern. The risk values for various soil exposure conditions are

summarized in Table 3-B-2.

Using these exposure values and the chemical-specific toxicity/cancer risk values, the target soil

concentrations were calculated. The attached spreadsheets, labeled Table 3-B-3 through 3-B-18

present the calculation of the PRGs as well as the target soil concentrations for protection of human

health.

Appendix B

Commercial/Industrial Worker Scenario

New RHE exposure values, consistent with the practices adopted for the other RHEscenarios, were developed for the commercial/industrial vapor intrusion scenario. The twofactors to develop for this exposure scenario are the exposure duration and the exposurefrequency. The median occupational tenure (both sexes, all occupations) is 6.6 years (U.S.EPA, 1997; Table 15-176). Nine years would reasonably represent an RHE scenario exposureduration. However, in order to maintain consistency with the outdoor commercial/industrialscenario which is part of the basis for the ROD cleanup levels, 25-year duration has beenselected for this scenario.

An RHE exposure frequency was developed based on work week statistics. The weightedmean hours per week worked (both sexes) is 21.82 hours (U.S. EPA, 1997; Table 15A-6). Anexposure frequency of 219 days per year reflects 35 hours per week worked over a 50 weekperiod (assuming 2 weeks vacation). This occupational exposure frequency, 219 days peryear (U.S. EPA, 1993), was selected for the RHE. From a practical standpoint, this is a highexposure for workers, as it assumes they are on the ground floor of the building and spendvery little working time elsewhere (e.g., out of the office for meetings or otherresponsibilities, in other buildings, or even on other floors of the same building).

Appendix C

Residential Vapor Intrusion Scenario

RHE values for the residential vapor intrusion scenario were developed consistent with thepractices adopted for the other RHE scenarios. The two factors to develop for this exposurescenario were the exposure duration and the exposure frequency. The 208-day exposurefrequency is based on the fraction of the time estimated to be spent at home in a 365-dayyear, adjusted for vacation, shopping and other personal and work related activities and thetime that is spent indoors as opposed to outdoors. Considering that the expected residentialuse is new urban construction, this exposure frequency exceeds the reasonably anticipatedtime spent at home per year. An exposure duration of 9 years was selected based on surveyresults that showed that the typical homebuyer was found to have lived in their previoushome between 4 and 7 years. The survey results indicate that the average tenure of homebuyers is 7.1 years based on an overall residence history of the respondents (U.S. EPA,1997). Nine years was selected as a representative value for the RHE. Thus, a residentialexposure of 208 days per year for 9 years is appropriate for use as the RHE vapor intrusionscenario.
