DECLARATION FOR THE RECORD OF DECISION
SITE NAME AND LOCATION
Chemical Insecticide Corporation
Edison Township, Middlesex County, New Jersey
STATEMENT OF BASIS AMD PURPOSE
This decision document presents the selected remedial action for
addressing contaminated soil and sediment in off-site residential
areas and areas in and immediately adj aceiit to the unnamed
tributary and Mill Brook associated with the Chemical Insecticide
Corporation site.. The remedial action was chosen in accordance
with the requirements of the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended,
and to the extent practicable, the National Oil and Hazardous
Substances Pollution Contingency Plan. This decision document
explains the factual and legal basis for selecting the remedy for
the site.
The New Jersey Department of Environmental Protection concurs
with the selected remedy. The information supporting this
remedial action decision is contained in the administrative
record for the site. •• .
ASSESSMENT OF THE SITE
Actual or threatened releases of hazardous substances from the
Chemical Insecticide Corporation site, if not addressed by
implementing.the response action selected in this Record of
Decision, may present an imminent and substantial endangerment to
public health, welfare, or the environment.
DESCRIPTION OF THE SELECTED REMEDY
The response action described in this document represents the
second of three planned remedial phases for the Chemical
Insecticide Corporation site. It.addresses contaminated soil and
sediment in residential areas and areas in and adjacent to the
unnamed tributary and Mill Brook.
A previous Record of Decision, signed on September 29, 1989,
selected an interim remedial action to control contaminated
runoff from the site. Construction of this interim action,
representing the first remedial phase for the site, was completed
in September 1994.
-------
The final remedy for the site will be selected after the
completion of additional soil washing treatability studies.
It will address contaminated soil on the site and in off-site
industrial areas as well as any associated groundwater contami-
nation.
The major components of the selected remedy for this second
remedial phase include the following:
D excavation of approximately 10,000 cubic yards of soil
and sediment containing arsenic at levels greater than
20 parts per million;
Q appropriate off-site disposal of contaminated soil and •
sediment; and
D restoration of the excavated areas to the extent
practicable.
The selected remedy provides protection of human health and the
environment by removing contaminated soil and sediment from the
above-described areas and restoring such areas.
Because this remedy does not include on-site containment of
contaminated material, long-term management and controls will not
be necessary.
DECLARATION OF STATUTORY DETERMINATIONS
The selected remedy is protective of human health and the
environment, complies with Federal and State requirements that
are legally applicable or relevant and appropriate, and is cost-
effective. It utilizes permanent solutions and alternative
treatment (or.resource recovery) to the maximum extent
practicable for the areas to be remediated. However, treatment
of the principal threats associated with the areas to be
remediated was not found to be practicable due to the
unavailability of an effective treatment technology at the
present time. Therefore, this remedy does not satisfy the
statutory preference for treatment as a principal element.
A five-year review of the remedy will not be necessary, because
it will not result in hazardous substances remaining in the
remediated areas above health-based levels.

SITE LOCATION AND DESCRIPTION
The Chemical Insecticide Corporation (CIC) site is located at 30
Whitman Avenue in Edison Township, Middlesex County, New Jersey.
The site occupies approximately 6 acres, bordered on the north by
Route 287 and on the east, west and south by industrial
properties. There are no permanent surface water bodies on the
CIC site. After heavy precipitation, the surface water runoff
drains toward the northeast corner of the site where it
discharges into an underground conduit which flows into an
unnamed tributary of Mill Brook. Mill Brook, in turn, flows into
the Raritan River approximately four miles downstream of the
site. Both the unnamed tributary and Mill Brook run through
residential areas, including two apartment complexes (Edison filen
and Edison Woods). Figure 1 of Appendix I indicates the site
location and the surface water flow pathway. The residents of
these complexes obtain potable water from a public water supply
system and none of these water bodies are used as a drinking
water source downstream of the site.
SITE HISTORY AND ENFORCEMENT ACTIVITIES
CIC owned and operated the site from 1954 to 1970. During this
time, the site was used for manufacturing insecticides,
fungicides, rodenticides and herbicides. These manufacturing
activities combined with poor housekeeping led to widespread
chemical contamination at the site, as well as migration of
contaminants to off-site areas.
Over the period of CIC operations, the Edison Department of
Health and Human Resources (EDHHR) became concerned about
activities on the site due to numerous neighborhood complaints of
odors, documented off-site discharges and releases, and the
frequency of on-site fires. In the late 1960s, EDHHR ordered the
cessation of on-site discharges of wastewater, required the
disposal of leaking drums to eliminate the odor problem, and the
closing of on-site lagoons. CIC declared bankruptcy in 1970.
The property was purchased in anticipation of future development
by Piscataway Associates, which demolished the production
facilities on the site in 1975. .
Triggered primarily by the potential for the presence of dioxin
(a contaminant generated in the production of 2,4,5-
trichlorophenoxyacetic acid, a herbicide which was handled on the
premises}, both the U.S. Environmental Protection Agency (EPA)
and the New Jersey Department Of Environmental Protection (NJDEP)
performed on-site and off-site field investigations at CIC,
testing soils and surface water for dioxin in 1983. In 1984,
NJDEP further sampled on-site soils for the presence of other
pollutants.
Based upon the analytical results from these investigations, EPA
Region II authorized a remedial investigation and feasibility
-------
study (RI/FS) for the site. On-site and off-site field
investigations were performed over the period from July 1987
through March 1988. In August 1990, EPA included the CIC site on
its National Priorities List of Superfund sites.
Concurrent with the RI/FS work, EPA conducted several immediate
actions to mitigate risks associated with the continuing problem
of contaminated surface water runoff from the site. These
included installation of a fence around site drainage areas,
improvements to site drainage controls and cleanup of
contaminated runoff from the adjacent Metroplex parking lot.
However, these limited response actions only partially addressed
the surface water runoff problem, in that the contaminated runoff
would continue to migrate to downstream waterways (i.e., the
unnamed tributary and Mill Brook), creating the potential for
adverse impacts to human health and the environment.
Interim Remedy
On September 29, 1989, EPA issued a Record of Decision (ROD)
selecting an interim remedial action to control contaminated
runoff from the CIC site. The major features of the selected
interim remedial action include: clearing and grading of the
site; covering the site with a surficial cap; construction of a
surface water runon diversion system; and controlled release of
collected, uncontaminated surface water runoff from the site.
This action represents the' first cleanup phase for the entire
site. Construction of this interim remedy was completed in
September 1994. Although it was anticipated that this interim
action would be completed in 1992, remedial construction was
delayed due to contractual problems as well as to address
concerns regarding the potential for buried explosives at the
site. Based on a subsequent explosives investigation, no buried
explosives were identified within the top two feet of surface
soil.
Final Remedy . . .
While proceeding with the interim remedial action, EPA continued
with the RI/FS, collecting additional samples and evaluating
final solutions for site-wide contamination. The combination of
chemical contaminants at the CIC site (herbicides, pesticides and
metals) requires the performance of treatability tests prior to
the identification of appropriate alternatives to remedy the
site. EPA has performed bench-scale incineration, solidification
and soil washing treatability testing since the issuance of the
interim remedy ROD in September 1989. Soil washing was deter-
mined to be ineffective in remediating site soils using the soil
washing procedure applied during the treatability test.
Therefore, the draft final feasibility study, which EPA issued in
March 1994, dismissed soil washing from further evaluation as a
potential remedial alternative for the CIC site.
-------
EPA has been working closely with the CIC Technical Assistance
Grant (TAG) Committee and its technical advisor regarding the
selection of a final remedy for the site. Based on its review of
the draft feasibility study, the TAG Committee suggested further
study of soil washing as a potential viable remedial alternative
for the CIC site. EPA has also further explored the viability of
soil washing with experts at its Office of Research and Develop-
ment which recommended pursuit of further optimization tests
based on new information. In addition, on July 27, 1994, the
Municipal Council of the Township of Edison adopted a resolution
requesting that EPA further evaluate the feasibility of soil
washing at CIC. Consequently, EPA has decided to perform a
follow-up soil washing treatability study involving the soils on
the CIC site. EPA expects that the additional •treatability study
will be completed in 1996.
If, upon further study, soil washing appears effective as a
potential remedial alternative, it will be evaluated in a revised
draft feasibility study report. Based on the results of the
feasibility study, EPA will release another proposed plan for
public comment which will identify the Agency's preferred final
remedy to address contaminated soil and groundwater. EPA expects
to propose this final remedy during 1997.
Remedy for Off~site Areas
Concurrent with the RI/FS and construction of the interim remedy,
EPA performed additional investigations in off-site areas to
determine the nature and extent of off-site contamination. Based
on the data generated during these investigations, EPA is
documenting its selected remedy for addressing contaminated soil
and sediment in residential areas and areas in and immediately
adjacent to the unnamed tributary and Mill Brook.
Enforcement Activities
Since the Chemical Insecticide Corporation is no longer in
existence, EPA has not been able to take enforcement action
against CIC for the problems caused by the company. However, EPA
has notified Mr. Arnold M. Livingston, who was the president of
CIC, of his potential liability with respect to the site.
HIGHLIGHTS 07 COMMUNITY PARTICIPATION
EPA has been working closely with the Edison Wetlands
Association, CIC Technical Assistance Grant (TAG) Committee, CIC
citizen's Advisory Committee, public officials and all other
interested and concerned members of the community. Their
participation and contributions to the site investigation/
remediation process have been and continue to be beneficial
towards achieving the Agency's goal of effectively protecting
-------
human health and the environment.
The Proposed Plan and supporting documentation for the second
cleanup phase associated with the CIC site were released to the
public for comment on November 7, 1994. These documents were
made available to the public in the administrative record
repositories maintained at the EPA Region II office (formerly, 26
Federal Plaza and currently, 290 Broadway, New York, New York),
the Edison Township Municipal Complex (100 Municipal Boulevard,
Edison, New Jersey), the Edison Library (340 Plainfield Avenue,
Edison, New Jersey), and the Metuchen Library (480 Middlesex
Avenue, Metuchen, New Jersey). A notice of availability for
these documents was published in The Star-Ledger on November 7,
1994. A public comment period on the documents was held from
November 7, 1994 to December 7, 1994.
On November 28, 1994, EPA and the New Jersey Department of
Environmental Protection conducted a public meeting at the Edison
Township Municipal Building, to inform local officials and
interested citizens about the Superfund process, to review the
planned remedial activities at the site, and to respond to any
questions from area residents and other attendees.
Responses to the comments recieved at the public meeting and in
writing during the public comment period are included in the
Responsiveness Summary (see Appendix V).
SCOPE AND ROLE OF ACTION
The CIC site, as characterized by the field investigations, is
extremely complex due to the number and variety of contaminants
present, the concentrations of contaminants, the physical and
geological characteristics of the site, and the many potential
migration routes for these contaminants. Consequently, EPA has
divided the response actions for the site into several remedial
phases as follows:
Interim Remedy; this remedial phase addressed the contaminated
surface water runoff conditions at the CIC site.
Final Remedy; this remedial phase will address contaminated soil
on the site and in off-site industrial areas, as well as
groundwater contamination associated with the CIC site. A final
remedy will be selected after the completion of additional soil
washing treatability studies, as described above.
Off-Site Remedy; this will address the remediation of contami-
nated soil and sediment in off-site areas associated with the CIC
site, as outlined in this ROD.
Since the purpose of this ROD is to document EPA's selected
-------
remedy for addressing soil and sediment contamination in off-site
areas, the subsequent summary of site characteristics focuses
only on the off-site investigation efforts.
SUMMARY OF SITE CHARACTERISTICS
Prior to construction of the above-described interim remedy,
contaminated surface water runoff drained toward the northeast
corner of the site where it discharged into an underground
conduit which flows into an unnamed tributary of Mill Brook. As
a result, off-site areas in and around the unnamed tributary and
Mill Brook are contaminated with contaminants from the CIC site.
Arsenic was used in pesticides produced by CIC during the 1950s
and 1960s and is the primary contaminant of concern involving the
off-site areas. Arsenic also occurs naturally in soil. NJDEP
has determined the upper limit of naturally occurring arsenic for
New Jersey soils to be 20 parts per million (ppm).
In October 1992, EPA collected five soil samples in residential
areas near the unnamed tributary and Mill BrooX and found
elevated levels of arsenic. Although the levels detected (up to
79.7 ppm) did not indicate an immediate risk to human health,
additional soil sampling to evaluate the long-term risk due to
exposure to arsenic contaminated soils was considered
appropriate.
As a result, in July 1993, the EPA Environmental Response Team
(ERT) conducted additional soil sampling in areas near the .
aforementioned streams. These areas included the Edison Glen and
Edison Woods developments, areas in Metuchen near Route 287, and
properties on Prince street, Patrick street and Cortlandt Street
in Edison, New Jersey. Four samples of dirt and/or dust from
building interiors and one well water sample were also collected.
The July 1993 sampling results indicated arsenic concentrations
were below 20 ppm in all but one off-site residential surface
soil sample (located within the Edison Glen condominium complex),
while higher levels, (up to 720 ppm) were found in and immediately
adjacent to the unnamed tributary and Mill Brook. The analytical
results of the dirt and/or dust samples indicated arsenic levels
consistent with background, or naturally occurring concentra-
tions. These results are summarized in EPA's October 20, 1993
correspondence in Appendix II.
In an attempt to define the extent of off-site contamination
associated with the CIC site, additional soil, sediment, surface
water, groundwater and interior dust sampling was performed by
EPA during March and April 1994. EPA conducted extensive
sampling at a number of locations including: 1) certain residen-
tial properties located along Wilshire Road and Rodak Circle, 2)
-------
the Edison Glen and Edison Woods residential complexes in Edison,
3) areas in and immediately adjacent to the unnamed tributary and
Mill Brook, and 4) areas in a Mill Brook tributary located along
the southern edge of the Edison Woods residential complex.
During this investigation, soil and sediment samples were
obtained in and around the unnamed tributary and Mill Brook at
thirty-one specific transect locations. Each transect location
is shown in Figure 1 (see Appendix I) as a solid line, designated
with an alphabetical letter or letters (A to Z and AA, BB, CC, DD
and EE), running perpendicularly through the unnamed tributary
and Mill Brook.
The following data resulting from the March/April 1994 sampling
effort indicate a similar distribution of arsenic as the July
1993 data:
o All but one of the residential surface soil samples (those
samples taken from a residential yard or common ground
within the Edison Glen and Edison Woods residential
complexes) indicated arsenic concentrations below 20 ppm.
o The analyses of soil samples taken from areas immediately
adjacent to the unnamed tributary and Mill Brook revealed
arsenic concentrations ranging from 0.2 to 1110 ppm. The
majority of the detected arsenic concentrations were below
20 ppm.
o The analyses of sediment samples taken from areas in the
unnamed tributary and Mill Brook generated arsenic concen-
trations ranging from 1.1 to 366 ppm. The majority of the
detected arsenic concentrations were below 20 ppm.
o The analyses of interior dirt and/or dust samples taken from
several apartments within, the Edison Glen residential
complex revealed arsenic concentrations ranging from 0.8 ppm
up to 11.3 ppm, indicating levels consistent with back-
ground, or naturally occurring concentrations.
EPA analyzed approximately ten percent of the samples for other
contaminants, in addition to arsenic. None of the residential
surface soil samples indicated the presence of any other contami-
nants at levels of concern. The soil and sediment samples taken
in and immediately adjacent to the unnamed tributary and Mill
Brook revealed elevated levels of several compounds, including
semi-volatile organic compounds [benzo(b)flouranthene-1.2 ppm,
benzo(a)pyrene-0.77-1.4 ppm, benzo(g,h,i)perylene-0.68 ppm,
benzo(k)flburanthene-1.7 ppm, benzo(a)anthracene-1.3 ppm], one
pesticide (dieldrin-0.005-0.099 ppm) and several inorganic com-
pounds (antimony-25 ppm, beryllium- 1.1-1.9 ppm, lead-103-244
ppm).
-------
The three surface water samples which were collected from
specific locations along the unnamed tributary and Mill brook
revealed the presence of several Volatile organic compounds,
herbicides, pesticides, and inorganic compounds, some of which
exceeded applicable federal or state surface water quality
criteria.
The results of EPA's 1994 sampling effort are summarized in EPA's
July 11, 1994 correspondence and data tables in Appendix II.
SUMMARY OF SITE RISKS
Based upon the results of the off-site investigations and
assuming a reasonable maximum exposure scenario (as described
below) , a baseline risk assessment (see Appendix IV) was
conducted to estimate the risks associated with current and
future exposure to soils and sediments in and around the unnamed
tributary and Mill Brook. The baseline risk assessment estimates
the human health and ecological risk which could result from the
contamination in these off-site areas if no remedial action were
taken. Based on a residential exposure scenario, which assumes
daily direct contact with contaminants, EPA also evaluated the
risks associated with the one residential area where elevated
levels of arsenic were detected (see Appendix IV) .
Health Risk ssessment •
As part of the Human Health Risk Assessment, the reasonable
maximum human exposure is evaluated by utilizing a four step
process for assessing site-related human health risks. The four-
steps consist of: Hazard Identification — identifies the contami.-
nants of concern at the site based on several factors such as
toxicity, frequency of occurrence, and concentration. Exposure
Assessment — estimates the magnitude of actual and/or potential
human exposures, the frequency and duration of these exposures,
and the pathways (e.g., ingesting contaminated wellwater) by
which humans are potentially exposed. Toxicity Assessment —
determines the types of adverse health effects associated with
chemical exposures, and the relationship between magnitude of
exposure (dose) and severity of adverse effects (response) . Risk
Characterization — summarizes and combines outputs of the exposure
and toxicity assessments to provide a quantitative assessment of
site-related risks.
Unnamed Tributary and Mill Brook Areas
The baseline risk assessment began with selecting contaminants of
concern which would be representative of off-site risks. In this
case, arsenic was determined to be the primary contaminant of
concern. Risk posed by other contaminants (excluding arsenic)
which were detected in soils and sediment in off -site areas was
-------
insignificant in comparison to arsenic and would not change the
conclusions of EPA's risk assessment.
The baseline risk assessment then identified the reasonable
maximum exposure scenario; it was presumed that adolescents
playing at the tributary or the Brook would be the most sensitive
potential receptors to the contamination. Adolescents (ages 7-
18) were assumed to play at the unnamed tributary or Mill Brook
once a week throughout the year, for 12 years. Exposure is
primarily related to the incidental ingestion of soils and sedi-
ments contaminated with arsenic. Under current EPA guidelines,
the likelihood of carcinogenic (cancer-causing) and non-
carcinogenic effects due to exposure to site chemicals are
considered separately. It is assumed that the toxic effects of
site-related chemicals are additive. Thus, carcinogenic and non-
carcinogenic risks associated with exposures to individual
compounds of concern are respectively summed, to indicate the
potential risks associated with mixtures of potential carcinogens
and non-carcinogens. A summary of the potential carcinogenic and
non-carcinogenic health effects is provided below.
o Carcinogenic Risk
Potential carcinogenic risks were evaluated using the cancer
slope factors developed by EPA for the contaminants of concern.
Cancer slope factors (SFs) have been developed by EPA's
Carcinogenic Risk Assessment Verification Endeavor for estimating
excess lifetime cancer risks associated with exposure to
potentially carcinogenic chemicals. SFs, which are expressed in
units of kilogram-day/milligrams (kg-day/mg), are multiplied by
the estimated intake of a potential carcinogen, in mg/kg-day, to
generate an upper-bound estimate of the excess lifetime cancer
risk associated with exposure to the compound at that intake
level. The term "upper bound" reflects the conservative estimate
of the risks calculated from the SF. Use of this approach makes
underestimation of the risk highly unlikely. The oral SF for
arsenic is presented in Appendix V. •
For known or suspected carcinogens, EPA considers excess upper-
bound individual lifetime cancer risks of between 10"* to 10* to
be acceptable. This level indicates that an individual has not
greater than approximately one in ten thousand to one in a
million chance of developing cancer as a result of site-related
exposure to a carcinogen over a 70-year lifetime under the
specific exposure conditions at the site.
The excess cancer risk for an adolescent exposed to arsenic in
the soils and sediment of the unnamed tributary and Mill Brook
(using the reasonable maximum scenario described above) is 5 X
10"6, which is within EPA's acceptable risk range. This can be
interpreted to mean that an individual would have a five in a
million excess risk of developing cancer if exposed to arsenic
8
-------
under the above-described scenario.
o Non-Carcinogenic Risk
Non-carcinogenic risks were assessed using a hazard index (HI)
approach, based on a comparison of expected contaminant intakes
and safe levels of intake (Reference Doses). Reference doses
(RfDsj have been developed by EPA for indicating the potential
for adverse health effects. RfDs, which are expressed in units
of milligrams/kilogram-day (mg/kg-day), are estimates of daily
exposure levels for humans which are thought to be safe over a
lifetime (including sensitive individuals). Estimated intakes of
chemicals from environmental media (e.g.. the amount of a
chemical ingested from contaminated drinking water) are compared
to the RfD to derive the hazard quotient for the contaminant in
the particular medium. The HI is obtained by adding the hazard
quotients for all compounds across all media that impact a
particular receptor population.
An HI greater than 1.0 indicates that the potential exists for
non-carcinogenic health effects to occur as a result of site-
related exposures. The HI for non-carcinogenic effects from
ingestion of arsenic in soils and sediments of the unnamed
tributary and Mill Brook (using the reasonable maximum exposure
scenario), was calculated to be 0.05 (see Appendix V). Therefore,
non-carcinogenic effects are highly unlikely to occur from the
exposure scenario evaluated in the risk assessment.
Residential Areas
In addition to the reasonable maximum exposure scenario evaluated
for the areas in and around the unnamed tributary and Mill Brook,
EPA also evaluated the risks associated with the one residential
area where elevated levels of arsenic were detected. Based on a
purely residential exposure scenario, which assumes daily direct
contact with contaminants, an area with arsenic contamination
significantly above 20 ppm (the upper concentration limit of
naturally occurring arsenic for New Jersey soils) in a residen-
tial area may pose a human health threat on a long-term exposure
basis. For the area behind Building 14 of the Edison Glen
Condominium complex, based on the reasonable maximum exposure
scenario, the carcinogenic risk was estimated to be 2 X 10",
which is at the high-risk end of EPA's acceptable risk range (see
Appendix V). In addition, the non-carcinogenic risk to a child
receptor was estimated, and an HI of 3.2 was calculated. This
indicates the potential for adverse non-carcinogenic effects.
Ecological Risk Assessment
A four-step process is utilized for assessing site-related
ecological risks for a reasonable maximum exposure scenario:
Problem Formulation—a qualitative evaluation of contaminant
-------
release, migration, and fate; identification of contaminants of
concern, receptors, exposure pathways, and known ecological
effects of the contaminants; and selection of endpoints for
further study. Exposure Assessment—a quantitative evaluation of
contaminant release, migration, and fate; characterization of
exposure pathways and receptors; and measurement or estimation of
exposure point concentrations. Ecological Effects Assessment—
literature reviews, field studies, and toxicity tests, linking
contaminant concentrations to effects on ecological receptors.
Risk Characterization—measurement or estimation of both current
and future adverse effects.
As with the Human Health Risk Assessment, arsenic was identified .
as the contaminant of concern in the ecological risk assessment
(see Appendix IV). The assessment quantitatively evaluated the
exposure pathways through which ecological receptors could be
exposed to arsenic. The most probable exposure pathways for
species inhabiting the areas in and immediately adjacent to the
unnamed tributary and Mill Brook include ingestion of
contaminated biota in the food chain and contact with or
ingestion of contaminants present in surface soils, surface water
and sediments. Receptor species, such as the deer mouse and
eastern cottontail rabbit, could be directly exposed to arsenic
through burrowing and grooming activities.
Potential risks to ecological receptors from arsenic present in
surface soil and sediments were assessed by calculating the ratio
of the medium-specific average and maximum contaminant concentra-
tions to the criteria. Criteria utilized include a benchmark
arsenic concentration at which the potential for chronic risk to
small mammals exists. If the resulting ratio or hazard index is
greater than 1..0, the biota may be at risk of an adverse effect
from the arsenic. When there is more than one contaminant of
concern in a media, a total hazard index is calculated by summing
all the chemical-specific hazard indices for each media. In this
case, since arsenic is the only contaminant of concern, there is
only one hazard index per media of concern. It follows that a
total hazard index greater than 1.0 indicates that exposure to
, all contaminants (in this case, only arsenic) of ecological
concern within that medium may pose a risk to organisms. A
literature search was also performed to gather and use all the
valuable existing information regarding arsenic effects on the
environment.
Results of the ecological risk assessment indicate that the
average and maximum total chronic hazard indices for the surface
soils are 2.0 and 27.4, respectively (calculated for small
mammals as represented by the deer mouse). This indicates that
adverse chronic ecological effects may occur in small mammals
such as the deer mouse. This risk is driven by arsenic, which is
the primary contaminant of concern. However, acute effects to
small mammals are unlikely as the receptor would not likely
10
-------
forage exclusively at locations where the potential exists for an
acute effect to begin in the small mammal population (only 6 in
over 115 locations with arsenic concentrations in surface soil
exceeded 245 milligrams per kilogram (mg/kg)— the potential
threshold for acute effects).
Based on a chronic exposure scenario, it was determined that, at
approximately 25 mg/kg of arsenic in surface soil, the potential
for risk to the deer mouse population exists. As a result of a
review of the existing information regarding arsenic effects in
the environment, it was also determined that chronic microbiota
effects begin at 375 mg/kg, acute earthworm effects begin at 150
to 165 mg/kg, and reduced plant productivity is noted at 25 to 85
mg/kg.
Risk to organisms at higher trophic levels (for example, at
levels above the deer mouse) via exposure through the food chain
was also assessed. It was determined that no risk to such
organisms via this pathway of exposure is anticipated.
Uncertainties
The procedures and inputs used to assess risks in this
evaluation, as in all such assessments, are subject to a wide
variety of uncertainties. In general, the main sources of
uncertainty include:
• environmental chemistry sampling and analysis
• environmental parameter measurement
• fate and transport modeling
• exposure parameter estimation
• toxicological data.
Uncertainty in environmental sampling arises in part from the
potentially uneven distribution of chemicals in the media
sampled. Consequently, there is significant uncertainty as to
the actual levels present. Environmental chemistry-analysis
error can stem from several sources including the errors inherent
in the analytical methods and characteristics of the matrix being
sampled. .
Uncertainties in the exposure assessment are related to estimates
of how often an individual would actually come in contact with
the chemicals of concern, the period of time over which such
exposure would occur, and in the models used to estimate the
concentrations of the chemicals of concern at the point of
exposure.
Uncertainties in toxicological data occur, in extrapolating both
from animals to humans and from high to low doses of exposure, as
well as from the difficulties in assessing the toxicity. of a
mixture of chemicals. These uncertainties are addressed by
11
-------
making conservative assumptions concerning risk and exposure
parameters throughout the assessment. As a result, the Risk
Assessment provides upper-bound estimates of the risks to
populations near the site, and is highly unlikely to
underestimate actual risks related to the site.
of H^^an Health and Ecological Risk
The results of the human health risk assessment indicate that/
based on the reasonable maximum exposure scenario evaluated for
the soils and sediments in and around the unnamed tributary and
Mill Brook, the excess carcinogenic risk is within EPA's
acceptable risk range, and adverse non-carcinogenic effects are
not likely to occur. However, under a residential exposure
scenario, an area with arsenic contamination significantly above
20 ppm may pose a human health threat on a long-term exposure
basis.
The ecological risk assessment concluded that the analytical
results of surface soil samples collected in the vicinity of the
unnamed tributary and Mill Brook indicate the presence of arsenic
at levels sufficient to generate acute risk to soil invertebrates
and chronic risk to soil microbiota and small mammals. Contami-
nants other than arsenic which were found in soil during the
investigation do not pose any significant risk to the terrestrial
community. In addition, surficial stream sediments in some areas
of the unnamed tributary and Mill Brook contain sufficient
arsenic to pose a risk to the benthic community (organisms living
on the tributary and brook bottoms). Isolated sediment sampling
locations also indicated sufficient levels of semi-volatile
organic compounds, pesticides and inorganic compounds to generate
risk to the benthic community.
Actual or threatened releases of hazardous substances from the
CIC site, if not remediated, may present a current or potential
threat to public health and the environment.
REMEDIAL ACTION OBJECTIVES
Remedial action objectives are specific goals to protect human
health and the environment. These objectives are based on
available information and standards such as applicable or
relevant and appropriate requirements (ARARs) and risk-based
levels established ,in the risk assessment. In order to address
potential human health and ecological risks, the remedial action
objective for the off-site remedy is to eliminate the potential
for exposure to contaminated soils and sediment in residential
areas and areas in and immediately adjacent to the unnamed tribu-
tary and Mill Brook.
12
-------
The human health risk assessment indicated that, based on the
reasonable maximum exposure scenario evaluated for the soils and
sediments in and around the unnamed tributary and Mill Brook, the
excess carcinogenic risk (5 X 10"6) is within EPA's acceptable
risk range, and adverse non-carcinogenic effects are not likely
to occur. However, under a residential exposure scenario, an
area with arsenic contamination significantly above 20 ppm may
pose a human health threat on a long-term exposure basis.
The ecological risk assessment indicated the potential for
adverse ecological effects if no remedial action is taken.
Because the unnamed tributary and Mill Brook currently exist as a
mature habitat corridor in an otherwise heavily developed area,
•the habitat value of "this area is increased and destruction of
the area in connection with the removal of contaminated soils and
sediment should be mitigated. However, its high ecological value
also increases the attraction of receptors into this potentially
hazardous habitat. Therefore, achieving a balance between
mitigating the potential risk to ecological receptors and
preserving the value of the habitat (or minimizing destruction of
the habitat through remedial activity) is preferred.
EPA has determined that the highest levels of arsenic are located
in •the soil and/or sediment in and around the area of transects
A, B, I, J, K, L, M, N, P, Q, S, V, W, X, Y, Z, and AA along the
unnamed tributary and Mill Brook, as.shown in Figure 1 of
Appendix I. These transect locations include all the areas
identified by the NJDEP as containing an arsenic concentration in
soil and/or sediment at or above 100 ppm. EPA believes that by
focusing remediation of soil and/or sediment in these areas, the
majority of the contamination would be removed while achieving a
reasonable and acceptable balance in preserving the ecology of
the area.
EPA plans to rely on NJDEP's determination of the upper limit of
naturally occurring arsenic for New Jersey soils (20 ppm) as a
criteria in remediating the above-described areas targeted for
cleanup. This same approach will be utilized to restore
contaminated residential areas (a backyard or common ground
within an apartment complex) such that any long-term risks
associated with these areas are removed. Although an arsenic
cleanup goal of 25 ppm would address the risks identified in the
ecological risk assessment, applying a soil/sediment cleanup
criteria of 20 ppm (or achieving an average residual arsenic
level of 20 ppm) also enables EPA to further mitigate the human
health risks.
DESCRIPTION OF REMEDIAL ALTERNATIVES
CERCLA requires that each selected remedy be protective of human
13
-------
health and the environment, be cost effective, comply with other
statutory laws, and utilize permanent solutions and alternative
treatment technologies and resource recovery alternatives to the
maximum extent practicable. In addition, the statute includes a
preference for the use of treatment as a principal element for
the reduction of toxicity, mobility, or volume of the hazardous
substances.
EPA's ability to exercise a preference for alternative treatment
technologies in identifying potential remedial alternatives for
the contaminated soils and sediment was limited for the following
reasons:
- insufficient information is available to evaluate treatment
technologies and their effectiveness in treating the contaminated
soils and sediment without performing additional- treatability
studies;
- the expeditious schedule required for remediation; and
- logistical problems associated with storage (until sufficient
additional treatability study work can be performed) of the off-
site contaminated soil and sediment at the CIC site due to the
recent completion of the above-described interim remedy.
In addition, containment of the contaminated material was also
considered but screened out prior to EPA's final evaluation of
alternatives. Because of the free-flowing and naturally
unpredictable conditions present in the areas of the unnamed
tributary and Mill Brook, in-situ containment was deemed
impracticable and excluded from the subsequent alternatives
evaluation.
Therefore, EPA has evaluated two remedial alternatives for
addressing off-site contaminated soil and sediment.
These alternatives are: .
Alternative l: No Action
Estimated Capital Cost: $0
Estimated Operation & Maintenance Cost: $0
Estimated Present Worth Cost: $0
Estimated Implementation Time: 0
The Superfund program requires that the "no-action" alternative
be considered as a baseline for comparison with other
alternatives. Under this alternative, EPA would not take any
action to remediate contaminated off-site soil and sediment.
Because this alternative would result in CIC contaminants
remaining in off-site areas, CERCLA requires that these areas be
reviewed every five years. If justified by the review, remedial
14
-------
actions may be implemented to remove or treat the contaminants.
Because the average arsenic level throughout the area would
remain above 20 ppm, NJDEP would recommend land use restrictions
(based on the New Jersey Industrial Site Recovery Act) to
eliminate the potential for direct contact.
Alternative 2: Excavation/Off-Site Disposal
Estimated Capital Cost: $8,583,000
Estimated Operation & Maintenance Cost: $0
Estimated Present Worth Cost: $0
Estimated Time to Design and Implement: 24 months •.
Alternative 2 includes excavation and off-site disposal of
contaminated soil and/or sediment within the areas of transects
A, B, I, J, K, L, M, N, P, Q, S, V, W, X, Y, Z, and AA along the
unnamed tributary and Mill Brook (as shown in Figure 1 of
Appendix I). In addition, contaminated soil in a grassy area
behind Building 14 of the Edison Glen Condominium Complex would
be excavated to 20 ppm arsenic for off-site disposal. This is
the only residential area warranting remediation.
The volume of soil and sediment to be excavated is estimated to
be 10,000 cubic yards, which is approximately equivalent to
14,100 tons of soil and sediment.
The estimated capital cost of $8,583,000 required to implement
Alternative 2 is a conservative estimate based on disposal of the
contaminated soils and sediment as hazardous waste at an EPA-
approved off-site hazardous waste landfill. Since it is possible
that this material may not be classified as a hazardous waste, it
may be disposed of at a non-hazardous waste facility, if such
authorized facility is willing to accept it. Disposal of the
material as non-hazardous waste at a non-hazardous waste facility
would reduce the estimated capital cost required to implement
Alternative 2 to $2,431,000.
The cost of this alternative also includes the cost of restoring
the excavated areas to the extent practicable. This would
include backfilling and revegetation to stabilize the excavated
areas.
Because average residual levels of arsenic will be below 20 ppm,
these areas would not be reviewed every five years and NJDEP
would not recommend any land use restrictions. Furthermore,
NJDEP's Stream Encroachment Regulations would serve to control
any future intrusive activities in and around the unnamed
tributary and Mill Brook.
15
-------
SUMMARY OF COMPARATIVE ANALYSIS OF ALTERNATIVES
During the detailed evaluation of remedial alternatives, each
alternative is assessed utilizing nine evaluation criteria as set
forth in the National Oil and Hazardous Substances Pollution
Contingency Plan (NCP) and Office of Solid Waste and Emergency
Response (OSWER) Directive 9355.3-01. These criteria were
developed to address the requirements of Section 121 of CERCLA to
ensure all important considerations are factored into remedy
selection decisions.
The following "threshold" criteria are the most important, and
must be satisfied by any alternative in order to be eligible for
selection;
o Overall protection of human health and the environment ad-
dresses whether or not a remedy provides adequate protection
and describes how risks posed through each pathway are
eliminated, reduced, or controlled through treatment, engi-
neering controls, or institutional controls.
o Compliance with applicable or relevant and appropriate
requirements addresses whether or not a remedy will meet all
of the applicable or relevant and appropriate requirements
of other federal and state environmental statutes and
requirements or provide grounds for invoicing a waiver.
The following "primary balancing" criteria are used to make
comparisons and to identify the major trade-offs between
alternatives:
o Long-term effectiveness and permanence refers to the ability
of a remedy to maintain reliable protection of human health
and the environment over time, once cleanup goals have been
achieved.
o Reduction of toxicity. mobility, or volume through treatment
is the anticipated performance of the treatment technologies
a remedy may employ.
o Short-term effectiveness addresses the period of time needed
to achieve protection and any adverse impacts on human
health and the environment that may be posed during the
construction and implementation period until cleanup goals
are achieved.
o Implementabilitv is the.technical and administrative
feasibility of a remedy, including the availability of
materials and services needed to implement a particular
option.
o Cost includes estimated capital and operation and
16
-------
maintenance costs, and net present worth costs.
The following "modifying" criteria are considered fully after the
formal public comment period on the Proposed Plan is complete:
o State acceptance indicates whether, based on its review of
the Proposed Plan and supporting documentation, the state
concurs, opposes, and/or has identified any reservations
with the preferred alternative.
o Community acceptance refers to the public's general response
to the alternatives described in the Proposed Plan and
supporting documentation. Factors of community acceptance
to.be discussed include support, reservation, and opposition
by the community.
A comparative analysis of these alternatives based upon the
evaluation criteria noted above follows.
o overall Protection of Human Health and the Environment
Alternative 1, no action, would not be protective of human health
and the environment as there would not be any action taken to
eliminate potential for direct contact with or ingestion of
contaminated soils and sediment. Since no remedial activities
would be implemented under this alternative, the risks posed to
human health and the environment would be the same as those
identified in the risk assessment. Alternative 1 is not
consistent with remedial action objectives.
Alternative 2 provides protection of human health and the
environment by removing the soils and sediment in the above-
described contaminated areas, and restoring such areas. By
eliminating the potential human health and ecological risks,
Alternative 2 would satisfy the remedial action objectives.
Furthermore, it balances the preservation of a valuable
.ecological habitat, while providing for removal of the majority
of the arsenic contamination. Removal of contaminated soils and
sediment also contributes to the improvement of surface water
quality in the unnamed tributary and Mill Brook.
o Compliance with ARARs
ARARs are those federal or state environmental and public health
regulations that apply to remedial activities at the site [or
area(s) to be remediated]. There are three classifications of
ARARs: chemical-specific, which are health- or risk-based concen-
tration limits; location-specific, which are based on the
geographical location of the site and its surroundings; and
action-specific, which are controls on particular types of
remedial activities.
17
-------
EPA plans to use 20 ppm as a criteria in remediating the contami-
nated soils and sediment in residential areas and areas in and
immediately adjacent to the unnamed tributary and Mill Brook.
Although this is not a promulgated chemical-specific standard,
and therefore not an ARAR, it does represent the upper limit of
naturally occurring arsenic concentrations in New Jersey soils.
Use of this criteria allows EPA to remove a large majority of the
arsenic contamination while achieving a reasonable and acceptable
balance in preserving a majority of the valuable ecology existing
in these areas.
Alternative 1 would not attain the chemical-specific criteria in
soils and sediment as it does not involve active remediation.
Action- and location-specific ARARs are not applicable as
Alternative 1 does not involve implementation of remedial
activities.
Alternative 2 is expected to attain all chemical-, location- and
action-specific ARARs. The chemical-specific cleanup criteria
for soils and sediment would be achieved, since the residual
average levels of arsenic will be below 20 ppm. All action- and
location-specific ARARs for remedial activities in wetlands and
floodplains would be achieved, including Section 404 of the Clean
Water Act, Executive Order 11990 (Protection of Wetlands), the
Flood Hazard Area Control Act (N.J.S.A. 16:50A) and the
Freshwater Wetlands Protection Act (N.J.S.A. 13:9B). The Occupa-
tional Safety and Health Act (OSHA) would apply to all workers
conducting the remedial activities specified under Alternative 2.
In addition and as discussed above, the excavated material may be
classified as a hazardous waste requiring adherence to
regulations involving the transport and off-site disposal of
hazardous waste. If necessary, the requirements of the Resource
Conservation and Recovery Act (RCRA), the Department of
Transportation (DOT) and the New Jersey Solid and Hazardous Waste
Regulations would be achieved through proper handling and
shipment of the contaminated material to an EPA-approved disposal
facility. A determination of the material classification would
be made during.design/implementation of Alternative 2 in order to
select an appropriate off-site disposal facility.
o Loner-Term Effectiveness and Permanence
Alternative 1 is not considered to be effective over the long
term as it does not include remediation of any off-site
contamination. Therefore, this alternative would not achieve the
remedial action objectives, since it would not reduce exposure to
contaminated soils and sediment in the subject areas. As
required by CERCLA, areas where contamination is left in place
must be reviewed every five years. If justified by the review,
remedial actions may be implemented to address the contaminated
areas.
18
-------
Alternative 2 includes removal of the majority of the arsenic
contamination, thereby eliminating the potential for human
exposure to and adverse ecological effects from contaminants at
levels of concern. As a result, a review of these areas every
five years is not required. This alternative is considered
effective over the long term and represents a permanent remedy to
address these areas, and does not require future monitoring,
operation or maintenance.
o Reduction in Toxicity. Mobility, or Volume
Alternative 1 does not include treatment of contaminated soils
and sediment, and therefore, does not reduce the toxicity,
mobility, or volume of contamination in the areas subject to
remediation. The contaminated material would remain in these
areas. .
As with Alternative 1, Alternative 2 is not expected to include
treatment. However, if so determined, the material excavated
under Alternative 2 may require treatment before it can be
disposed of in an off-site landfill. Such treatment may result
in a reduction of the toxicity and mobility of contamination.
o Short-Term Effectiveness
Since there are no remedial activities being implemented under
Alternative 1, there would be no additional.short-term risks
posed to human health or the environment.
The time required to implement Alternative 2 is estimated to be
24 months. No additional risks to human health or the
environment are expected as a result of the implementation of
these activities. Due to the intrusive nature of soil and
sediment removal, there may be potential risks posed to workers
during the remedial activities. Worker protection would be
required to prevent direct contact with contaminated material
during the excavation effort. In addition, workers .would be
trained in health and safety, and protective equipment would be
provided during construction activities.
The excavation effort would cause significant disruption to areas
in and around the unnamed tributary and Mill Brook. While EPA
plans to minimize the destruction of trees in these areas, it is
expected that a number of trees would be removed. The related
activities would also require stream encroachment and disturbance
of sediments. However, EPA would take the appropriate steps to
adequately control water flow and sediment runoff. Upon
completion of the excavation activities) the disturbed areas
would be restored and stabilized by backfilling and revegetating.
Since the remedial activities would occur in and around
residential areas, EPA anticipates that these activities may be
19
-------
considered disruptive to some or all residents. For example, a
high volume of traffic is expected to occur during the soil and
sediment removal activities. EPA would take appropriate and
reasonable measures to ensure that proper traffic controls are
implemented and that impacts to affected residents are minimized.
EPA would work closely with the community during the remedial
design period to coordinate these construction-related
activities.
o Implementability
*
There are no implementability concerns posed by Alternative 1
since no remedial action would be taken under this alternative.
Alternative 2 would be difficult to implement due to the large
volume of material to be excavated and the limited accessibility
to the areas to be remediated. Temporary access roadways would
be constructed to provide necessary vehicular equipment access to
areas to be remediated in and immediately adjacent to the unnamed
tributary and Mill Brook.
In addition, attempts would be made during implementation of the
remedial action to minimize tree removal, which would likely
require additional time for the excavation work.
o Cost
Since Alternative 1 does not include any remedial activities,
there are no costs associated with this alternative.
Since Alternative 2 does not require operation and maintenance,
present worth and operation and maintenance costs were not
estimated. The estimated capital cost associated with
Alternative 2 is $8,583,000 and $2,431,000 assuming off-site
disposal of contaminated material as hazardous and non-hazardous
waste, respectively.
o State Acceptance
The State of New Jersey concurs with EPA's preference of
Alternative 2.
o Community Acceptance
In general, both public officials and community residents
expressed support for Alternative 2. A more detailed discussion
of community concerns is presented in the Responsiveness Summary-
SELECTED REMEDY
Based upon consideration of the requirements of CERCLA, the
detailed analysis of the alternatives, and public comments, both
20
-------
EPA and the New Jersey Department of Environmental Protection
have determined that Alternative 2 is the most appropriate remedy
to address soil and sediment contamination related to the CIC
site in and around off-site residential areas.
Alternative 2 includes excavation and off-site disposal of
contaminated soil and/or sediment within the areas of transects
A, B, I, J, K, L, M, N, P, Q, S, V, W, X, Y, Z, and AA along the
unnamed tributary and Mill Brook (as shown in Figure 1 of
Appendix I). In addition, contaminated soil in a grassy area
behind Building 14 (also shown in Figure 1 of Appendix I) of the
Edison Glen Condominium Complex will also be excavated for off-
site disposal.
Approximately 10,000 cubic yards of soil and sediment will be
removed and the remediated areas will be appropriately restored.
This approach enables EPA to restore contaminated residential
areas such that any long-term risk associated with these areas is
removed and no property use restrictions will be required. By
also targeting specific contaminated areas in and near the
unnamed tributary and Mill Brook, EPA is able to remove a
significant portion of the CIC contamination while achieving a
reasonable and acceptable balance in preserving the ecology of
the area. Furthermore, because the average residual levels of
arsenic will be to be below 20 ppm, it will not be necessary to
perform five-year review in connection with the off-site areas or
require the imposition of land use restrictions.
The selected remedy is the most protective of human health and
the environment because it eliminates the risk associated with
exposure to contaminated soil and sediment by both human and
ecological receptors. Alternative 1 is not protective of human
health and the environment.
Due to the large volume of material to be excavated and the
limited accessibility to the areas to be remediated, Alternative
2 will be difficult to implement. However, the benefits of the
selected remedy outweigh any associated implementability issues.
EPA will work closely with the community during the remedial
design period and to coordinate construction activities.
Future use of the off-site areas being targeted for remediation
is also an important consideration. These areas would likely be
restricted from future use under Alternative 1 in order to
control exposure to contaminated soils and sediment. However,
under the selected remedy, a greater degree of flexibility exists
regarding future use of the areas targeted for remediation, as
land use restrictions will not be required.
The selected remedy is much higher in cost than Alternative 1.
However, when evaluating the cost effectiveness of the ,
alternatives, which is determined by weighing the cost against
21
-------
the alternative's ability to achieve ARARs and remedial action
objectives, the selected remedy is cost effective. Unlike
Alternative 1, the selected remedy achieves a balance in
preservation of the ecology while eliminating the potential for
exposure to contaminated soils and sediments in the areas
targeted for remediation.
The selected remedy provides the best balance of trade-offs among
alternatives with respect to the evaluation criteria. EPA and
NJDEP believe that the selected remedy will be protective of
human health and the environment, will comply with ARARs, will be
cost effective, and will utilize permanent solutions and alterna-
tive treatment technologies or resource recovery technologies to .
the maximum extent practicable.
STATUTORY DETERMINATIONS
Under its legal authorities, EPA's primary responsibility at
Superfund sites is to undertake remedial actions that are protec-
tive of human health and the environment. In addition, Section
121 of CERCLA establishes several other statutory requirements
and preferences. These specify that when complete, the selected
remedial action must comply with applicable or relevant and
appropriate environmental standards established under federal and
state environmental laws unless a statutory waiver is justified.
The selected remedy also must be cost effective and utilize
permanent solutions and alternative treatment technologies or
resource recovery technologies to the maximum extent practicable.
Finally, the statute includes a preference for remedies that
employ treatment that permanently and significantly reduce the
volume, toxicity, or mobility of hazardous wastes, as available.
The following sections discuss how the selected remedy meets
these statutory requirements.
Protection of Human Health and the Environment
The selected alternative provides protection of human health and
the environment by removing the soils and sediment in the above-
described contaminated areas, and restoring such areas. The
excavated contaminated material will be disposed at a secure
landfill, thereby preventing any future negative impacts to the
surrounding environment. Alternative 2 balances the preservation
of an ecological habitat, while providing for removal of the
majority of the arsenic contamination. Because this remedy
involves removal of a limited portion of the areas in and around
the unnamed tributary and Mill Brook, short-term and long-term
impacts to the ecosystem are minimized. Removal of contaminated
soils and sediment also contributes to the improvement of surface
water quality in the unnamed tributary and Hill Brook.
22
-------
Compliance with ARARs
The selected remedy is expected to comply with all ARARs
necessary to achieve the above-described remedial action
objectives. The remedy is designed to comply with all action-
and location-specific ARARs that pertain to remedial activities
in wetlands and floodplains. The chemical-specific cleanup
criteria for soils and sediment will be achieved since the
residual average levels of arsenic will be below 20 ppm. All
action-specific ARARs identified under OSHA will apply to all
workers conducting the remedial activities specified under the
selected remedy. In addition and as discussed above, the
selected remedy may require classification of the excavated
material as a hazardous waste and, therefore, be required to
adhere to regulations involving the transport and off-site
disposal of hazardous waste. If the soils and sediment are
classified as hazardous waste, 'the remedy will comply with the
requirements of the Resource Conservation and Recovery Act, the
Department of Transportation and the New Jersey Solid and
Hazardous Waste Regulations will be achieved through proper
handling and shipment of the contaminated material to an EPA-
approved disposal facility. A determination of the material
classification will be made during design/implementation of the
selected remedy in order to select an appropriate off-site
disposal facility.
Cost Effectiveness
When evaluating the cost effectiveness of.the alternatives, which
is determined by weighing the cost against the alternative's
ability to achieve ARARs and remedial action objectives, the
selected remedy has been determined to be the most cost
effective.
Utilization of Permanent Solutions and Alternative Treatment
Technologies to the Maximum Extent Practicable
The selected remedy represents the maximum extent.to which
permanent solutions and treatment technologies can be utilized in
an expeditious and cost effective manner to remediate CIC
contamination in and around off-site residential areas. Although
the selected remedy does not involve the reduction of toxicity,
mobility, or volume through treatment, it provides long- and
short-term effectiveness, and is cost effective.
Preference for Treatment as a Principal Element
The selected remedy does not satisfy the preference for treatment
as a principal element. Treatment of the principal threats of
the areas to be remediated was not found to be practicable
because no effective treatment technology is readily available at
this time.
23

DOCUMENTATION OF SIGNIFICANT CHANGES
There have been no significant changes in the selected remedy
from the preferred remedy described in the Proposed Plan.

JACOB K. JAVITS FEDERAL BUILDING
NEW YORK. NEW YORK 10278-O012
October 20, 1993
Dear Resident:
The purpose of this letter is to inform you of the test results for
the soil samples collected by the U. S. Environmental Protection
Agency (EPA) from July 6 through 8, 1993. The testing was
performed to better define the extent of contamination associated
with the Chemical Insecticide Corporation (CIC) Superfund site at
30 Whitman Avenue, Edison, New Jersey. The samples were collected
at a number of locations including: 1) properties on Prince
Street, Patrick Avenue and Cortland Street in Edison, 2) the Edison
Glen and Edison Woods residential complexes in Edison, and 3) areas
in Metuchen near Route 287. Four samples of dirt and/or dust from
building interiors and one well Water sample were also collected.
This sampling effort was a follow-up to soil sampling performed by
EPA in October of 1992 near Mill Brook and an unnamed creek, two
streams that receive drainage from the CIC site. Some levels of
arsenic found in the 1992 samples were higher than levels typically
found in New Jersey soils. However, because those samples were
taken mainly on the banks of the two streams, it was not known
.vhether the elevated concentrations bf arsenic extended from the
streams to areas closer to the nearby buildings. The July 1993
sampling effort included additional sampling on the banks of the
streams as well as soil samples taken closer to the nearby
buildings. The July 1993 project involved the collection of sixty-
seven samples, as compared to only nine samples collected in
October of 1992. -
Arsenic was used in pesticides produced by the Chemical Insecticide
Corporation during the 1950's and 1960's. Arsenic also occurs
naturally in soils and is typically found at concentrations between
5 to 30 parts per million (ppm) in New Jersey. Higher or lover
concentrations are found in different geographic areas. An
extensive study was conducted to establish naturally occurring
background concentrations of arsenic for a Superfund site in
Middlesex County. Background concentrations for arsenic were found
to be 28 ppm. .
The July 1993 sampling results are presented in an EPA document
entitled: "Final Report, Off-Site Characterization, Chemical
Insecticide Site, Edison, NJ" dated September, 1993. The results
are summarized on the attached map. Arsenic concentrations were
below 28 ppm in all but one off-site .soil samples except those in
the immediate vicinity of the unnamed creek and Mill Brook.
PRINTED ON RECYCLED PAPER
-------
LFA's preliminary evaluation the data Indicates that the potential
exposure to arsenic contaminated soil does not present an immediate
heath risk. Although the highest concentrations of arsenic for the
July 1993 samples are greater than the highest concentrations found
in samples collected in October 1992, the recent data indicates
that soil arsenic levels decrease to normal levels with increasing
distance from the streams. The new sampling results indicate that
the arsenic contamination is limited chiefly to the outskirts of
properties along the two streams. This limited spacial
distribution of the arsenic contamination reduces the potential for
human exposure to the arsenic. However, there is concern that
exposure to arsenic levels found near the creek and brook may be of
concern over the long-term.
EPA has made the July 1993 sampling results available to the
Federal Agency for Toxic Substances and Disease Registry (ATSDR)
and to the New Jersey Department of Health (NJDOH) for review and
comment. The initial review of the sampling results by ATSDR and
NJDOH confirmed EPA's preliminary evaluation. ATSDR and NJDOH
concurred that the arsenic levels documented in the July 1993
sampling event do not pose an immediate public health threat.
However, ATSDR and NJDOH did express the concern that the arsenic
levels may pose a public health threat on a long-term exposure
basis. EPA, ATSDR and NJDOH plan to continue to evaluate the
potential health risks associated with the off-site arsenic
contamination. .
Since there is no concern about immediate health effects due to
potential short-term exposure to arsenic contamination, EPA plans
to address the concerns related to long-term exposure as part of
the complete remedy for the site. EPA anticipates selecting a
cleanup plan for the site in the Spring of 1994. Excavation of
off-site soils would be expedited, following the selection of a
remedy.
Anticipating that community residents, property owners and others
•may have questions about this matter, EPA has scheduled a public'
meeting to provide additional information and answer questions
about the CIQ site. ATSDR and NJDOH also plan to participate in
this meeting. The time and place are: .

QUESTIONS AND ANSWERS
CONCERNING OFF-SITE SAMPLING RESULTS
FOR THE CHEMICAL INSECTICIDE SITE, EDISON, NEW JERSEY
te then an Immediate problem that needs to be
addressed on an emergency basis?
The concentrations of arsenic found off-site do
not pose a short-term health threat; therefore,
an Immediate action Is not required. EPA uses
aiange of 1000 to 2000 pom of arsenic to
determine when an immediate action is
warranted.
is there a concern about effects from long-term
exposure?
In limited areas around the unnamed creek and
MDI Brook, long-term exposure to the
concentrations of arsenic found may be of
concern. This concern is based on repeated
ingestion of the most contaminated soils over
many years. However, the location of
contaminated soBs reduces the likelihood for
exposure to arsenic.
Have the appropriate health agencies reviewed
the data?
Both the Agency for Toxic Substances and
Disease Registry and the New Jersey
Department of Health have reviewed the results.
These Agencies have independently concluded
that while there may be a concern about the
effects of long-term exposures, there is no
immediate public health threat associated with
the concentrations of arsenic found off-site.
WHI the contamination be cleaned up?
Since there is no immediate public health threat
associated with off-site contaminated soils, EPA
plans to dean up the areas around the
unnamed creek and Mill Brook as part of the
complete remedy for the CIC site. This remedy
should be selected by the Spring of 1994.
Excavation of off-site sons will be expedited,
once the remedy is selected.
Wtt acUOontl off-cte tot aampfing be
performed?
There is sufficient sampling to determine that a
remedy te warranted for off-site sol& Additional
samples wll be taken as part of the complete
remedy to define the boundaries of off-ste
areas to be excavated.
What levels of arsenic In effete aofls will
require long-term cteanup?
EPA is currently working with the New Jersey
Department of Environmental Protection and
Energy to establish a cleanup level for the CIC
she. An extensive study was conducted to
determine background concentrations of arsenic
for another Superfund site in Middlesex County.
.The study Indicated that 28 ppm was
background for the area EPA anticipates that
the deanup level wll be In the 20 ppm range.
What off-site areas require cleanup?
Of the 62 sol samples collected, 20 exceed 20
ppm. All of the samples that exceeded 20 ppm
are adjacent to the unnamed creek or Mill
Brook.
Win the Interim cap address cff-sfte
contamination?
The Installation of a cap would prevent future
.migration of contaminated stormwater runoff
from the CiCsite, but would not address the
current off-site conditions.
" When *W the Interim cap be Instated on the
CICste?
The contractor which wB be conducting an
investigation for explosives waste has begun
mobBizing equipment to the site. The
explosives waste investigation is scheduled to
begin shortly. H the explosives Investigation
shows that there is not a significant problem.
then mobilization for cap construction should
begin In December. .

Re: Chemical Insecticide Corporation Superfund site
Dear Resident and/or Property Owner:
This letter is to inform you of the results of soil, sediment,
surface water and groundwater sampling performed by the U.S.
Environmental Protection Agency (EPA) from March 14 .through April 1,
1994. EPA is pleased to report that the recent sampling results are
consistent with previous testing, and indicate that there is no
immediate health threat posed by off-site arsenic contamination.
The sampling was intended to further measure the extent of potential
off-site contamination associated with the Chemical Insecticide
Corporation (CIC) Superfund site at 30 Whitman Avenue, Edison, New
Jersey. The samples were collected at a number of locations
including: 1) certain residential properties located along Wilshire
Road and Rodak Circle, 2) the Edison Glen and Edison Woods
residential complexes in Edison, 3) areas in and immediately adjacent
to the unnamed stream and Mill Brook, and 4) areas in a Mill Brook
tributary located along the Southern edge of the Edison Woods
residential complex. Three samples of dirt and/or dust from certain
apartments and one well water sample were also collected. The
results are summarized in the attached figures.
As you may be aware, arsenic was used in pesticides produced by the
Chemical Insecticide Corporation during the 1950's and 1960's and is
the primary contaminant of concern for the site. Arsenic also occurs
naturally in soils and is typically found at concentrations between 5
to 30 parts per million (ppm) in New Jersey. Higher or lower
concentrations are found in different geographic areas. The New
Jersey Department of Environmental Protection and Energy has
determined the upper limit of naturally occurring arsenic
concentration for New Jersey (including Edison) to be 20 ppm.
This recent sampling effort was a follow-up to soil sampling
performed by EPA in July of 1993 at a number of locations including
properties on Prince Street, Patrick Avenue and Cortland Street in
Edison; the Edison Glen and Edison Woods residential complexes in
Edison; and areas in Metuchen near Route 287.. The July 1993 sampling
results indicated arsenic concentrations were below 20 ppm in all but
one off-site residential soil sample, while higher levels were found
in and immediately adjacent to the unnamed stream and Mill Brook.
The attached arsenic data resulting from the March/April 1994
sampling effort indicate a similar distribution of arsenic as
follows:
miWTED ON RECYCLED PATER
-------
All but one of the residential soil sample (those samples taken
from a residential yard or common ground within Edison Glen and
Edison Woods residential complexes) analyses indicated arsenic
concentrations below 20 ppm. Figures 1, 2, 3, and 5 provide the
data associated with each of such sampling locations. The
dumpster area shown in Figure 3 indicates the location of the
one residential soil sample which generated an arsenic
concentration above 20 ppm.
The analyses of soil and sediment samples taken from areas in
and immediately adjacent to the the unnamed stream and Mill
Brook generated arsenic concentrations ranging from less than 1
up to 1100 ppm. The majority of the detected concentrations
vere below 20 ppm. Figure 6 provides the data associated with
each of these samples.
The three dirt and/or dust samples collected from specific
apartments within the Edison Glen condominium complex indicated
arsenic concentrations which ranged from approximately 0.8 ppm
up to 11.3 ppm. Figure 4 provides the data associated with each
of these apartments.
Soil j,n Residential Yards /Coupon Areas
EPA's evaluation of the off-site sampling data indicates that the
potential exposure to arsenic does not present an immediate health
risk. As stated above, with the exception of one sample, all soil in
residential areas contained arsenic at concentrations of less than 20
ppm, which is consistent with naturally occurring levels in New
Jersey. However, since arsenic contamination significantly above 20
ppm in a residential yard or common grounds within Edison Glen or
Edison Woods residential complexes may pose a.long-term risk, this
contamination will be remediated by EPA.
Soil/Sediment in Unnamed Stream/Mill Brook
A Risk Assessment was conducted to estimate the human health risks
associated with potential exposures to arsenic detected in the soils
and sediments in and immediately adjacent to the Unnamed Stream and
Kill Brook. The risk assessment was conducted using a highly
conservative estimate of exposure* which is likely to overestimate
the health risks related to the unnamed stream and Mill Brook. This
risk assessment identified adolescents playing at the stream or the
Brook as the most sensitive potential receptors to the contamination.
Adolescents (ages TylS) were assumed to play at the unnamed stream or
Mill Brook once a week throughout the year, for 12 years. Exposures
were assumed to occur primarily through incidental ingestion of soils
and sediments contaminated with arsenic.
Based on the Risk Assessment for soils and sediments of the stream
and brook, there is no unacceptable risk to human health posed by
exposure to these areas. For known or suspected carcinogens such as
arsenic, EPA considers excess upper-limit individual lifetime cancer
-------
risks of between 10*4 and 104 to be acceptable. This range indicates
that an individual has not greater than approximately a one in ten
thousand to one in a million chance of developing cancer as a result
of site-related exposure to a carcinogen under the specific exposure
conditions at the site. The excess cancer risk for an adolescent
exposed to arsenic in the soils and sediments in and immediately
adjacent to the unnamed stream and Mill Brook (using the conservative
assumptions outlined above) is 5 x 10"*, which is well within EPA's
acceptable risk range. In addition, non-carcinogenic effects are
also highly unlikely to occur from the exposure scenario evaluated in
the Risk Assessment.
Interior Dust
The level of arsenic found in the interior dust samples at the Edison
Glen complex is generally consistent with the concentrations found in
the surficial soils at Edison Glen, thus, suggesting that the major
contributing factor to the interior arsenic levels is the soil
derived dust (with naturally occurring levels of arsenic below 20
ppra) from outside the dwellings. The risk associated with the
arsenic levels detailed above would also fall within EPA's acceptable
excess lifetime cancer risk range of between 10*4 and 104 and would
not pose a non-carcinogenic hazard for residents of the Edison Glen.
Public Availability Session and Meeting
EPA has scheduled an availability session and public meeting to
provide additional information and answer questions that community
residents, property owners and others may have regarding the attached
results and the CIC site. The availability session will be held from
1:00-4:00 PM and will be followed by a public meeting in the evening
from 7:00-10:00 PM on Thursday, July 14, 1994 at the Stelton
Community Center (Auditorium) located at 328 Plainfield Avenue in
Edison, New Jersey (908-248-7309).
Please feel free to contact me at (212) 264-6311, or Ms. Cecilia
Echols, Community Relations Coordinator, at (212) 264-0949.

Dear Mr. Muszynski:
The Department of Environmental Protection has evaluated and concurs with the Chemical
Insecticide Corporation (CIC) Superfund Record of Decision (ROD) (see attached ROD
dated March 9,1995) which addresses contaminated soil and sediments located in residential
and recreational areas.
The Department is aware that this ROD represents the second of three phases for the site.
The first phase, which was implemented in September 1994, addressed contaminated runoff
leaving the site. The third and final phase is expected to address on-site contaminated soil
and associated groundwater contamination.
The specific components of the selected remedy for the second phase of the remediation
as outlined in the ROD include the following:
* excavation of approximately 10,000 cubic yards of soil and sediment
containing arsenic at levels greater than 20 parts per million;
* appropriate off-site disposal of contaminated soil and sediment; and
' restoration of the excavated areas to the extent practicable.
The State of New Jersey appreciates the opportunity to participate in the decision mating
process and looks forward to future cooperation with the USEPA.

Human Health Risk Assessment Summary
Unnamed Creek and Mill Brook
r
-------
Integrated Risk Information System (IRIS). Under
current EPA guidelines, the likelihood of carcino-
genic (cancer-causing) and noncarcinogenic effects
due to exposure to site chemicals are considered
separately. Noncarcinogenic risks were assessed
using a hazard index (HI) approach, based on a
comparison of expected contaminant intakes and
safe levels of intake (Reference Doses). Reference
doses (RfDs) have been developed by EPA for
indicating the potential for adverse health effects.
RfDs, which are expressed in units of milligrams/ki-
logram-day (mg/kg-day), are estimates of daily
exposure levels for humans which are thought to be
safe over a lifetime (including sensitive individuals).
Estimated intakes of chemicals from environmental
media (e.g., the amount of a chemical ingested from
contaminated sediments) are compared to the RfD
to derive the hazard quotient for the contaminant
in the particular medium. The HI is obtained by
adding the hazard quotients for all compounds
across all media that impact a particular receptor
population.
An HI greater than 1.0 indicates that the potential
exists for noncarcinogenic health effects to occur as
a result of site-related exposures. The reference
dose for arsenic is 3 x 10"4. The HI for noncarcin-
ogenic effects from ingestion of arsenic in soils and
sediments of the Unnamed Creek and Mill Brook
(using the reasonable maximum exposure for
adolescents) is 0.05, therefore, noncarcinogenic
effects are highly unlikely to occur from the expo-
sure scenario evaluated in the Risk Assessment.
Potential carcinogenic risks were evaluated using
the cancer slope factor developed by EPA for
arsenic. Cancer slope factors (SFs) have been devel-
oped by EPA's Carcinogenic Risk Assessment Verifi-
cation Endeavor (CRAVE) for estimating excess
lifetime cancer risks associated with exposure to
potentially carcinogenic chemicals. SFs, which are
expressed in units of (mg/kg-day)'1, are multiplied
by the estimated intake of a potential carcinogen, in
mg/kg-day, to generate an upper-bound estimate of
the excess lifetime cancer risk associated with
exposure to the compound at that intake level. The
term "upper bound" reflects the conservative esti-
mate of the risks calculated from the SF. Use of
this approach makes the underestimation of the
risk highly unlikely. EPA has classified arsenic as
a known human carcinogen, and the SF for arsenic
is 1.75 (mg/kg-d)'1.
For known or suspected carcinogens, EPA considers
excess upper-bound individual lifetime cancer risks
of between 10"4 and 10"6 to be acceptable. This level
indicates that an individual has not greater than a
one in ten thousand to one in a million chance of
developing cancer as a result of site-related expo-
sure to a carcinogen under the specific exposure
conditions at the site. The excess cancer risk for an
adolescent exposed to arsenic in the soils and sedi-
ments of the Unnamed Creek and Mill Brook (using
the reasonable ma-Tin-m-m exposure scenario) is 5 x
10"*, which is well within EPA's acceptable risk
range.
CONCLUSIONS
The results of the risk assessment indicate that the.
health risks associated with contact arsenic in the
soils and sediments of the Unnamed Creek and Mill
Brook are well within EPA's acceptable risk range.
The risk assessment utilized the reasonable maxi-
mum exposure scenario, which is likely to overesti-
mate the health risks associated with the potential
exposures to arsenic in the Unnamed Creek and
Mill Brook.

DATE: November 3, 1994
SUBJECT: Arsenic Risk at Edison Glen Development
FROM: Mark Maddaloni
TO: Pat Evangelista
The remediation of soils in the dumpster area of the Edison
Glen Housing Development is premised on the results of the risk
assessment that was performed on the sampling data in that area.
As is indicated in Table 1, the excess lifetime cancer risk
under a residential land-use scenario is 2.0 E-04. The
corresponding Hazard Quotient (for a child receptor) is 3.2.

Lockheed EfSAT Technical Review
ESAT Site-Specific Follow-up ERA for Chemical Insecticide Corp.
The following are the quick turn-around results of the ESAT desk-
top ecological risk assessment (ERA) using methodologies derived by
ESAT, and data from Eisler, McVey, Persaud, and the "Draft Off-site
Investigation Report." This report was dated June 24, 1994, and
prepared by Roy F. Weston, Incorporated, for the Chemical
Insecticide Corporation (CIC) site in Edison Township, Middlesex
County, New Jersey.
Using a chronic toxicity benchmark for arsenic, the potential for
risk to snail mammals, represented by the deer mouse, is present
from the CIC off-site stream area surface soils at maximum (680
rog/kg) and mean (50.3 mg/kg) soil concentrations of arsenic. The
"maximum and mean levels generate hazard indices (His) of 27.4 and
2.0, respectively. No chronic risk is anticipated at the median
(14.2 mg/kg) concentration (HI =0.6).
No acute toxicity is anticipated to the mouse at even the maximum
exposure concentration (28.8 mg/kg/day), but exposure at this
concentration does exceed the LD-0, or no effect, level of .10.4
mg/kg/day (Sisler). Therefore, using the LD-0 indicates that there
is the potential for an acute effect to begin in the mouse
population at soil concentrations exceeding 245 mg/kg. Only six in
over 115 surface soil samples exceed this concentration, and only -
two more approach it. Therefore, acute'effects to small mammals .
are unlikely, as the receptor.would not likely forage exclusively
at those locations. ' • .
To further support this assessment, acute risk was assessed for the
eastern cottontail. No chronic risk was assessed because an
appropriate ben_:.'mark could not be readily located. The potential
for acute risk was-found based on the maximum soil concentration
(HI = 1.4). No potential for acute risk was found at the mean
concentration (HI = 0.1). (.Due to the low HI for the mean, the
median level was not-assessed.) Extrapolating from the maximum
surface soil concentration and its corresponding HI, the potential
for acute effects can be anticipated at surface soil levels
exceeding 485 mg/kg. As only two surface soil levels exceed this
concentration, and no others approach it, no acute effects are
anticipated.
Calculating an effect level that would be anticipated based on the
chronic exposure scenario for the mouse yields a soil level at
which there is a potential for risk at 24.82 mg/kg, or
approximately 25 mg/kg. Based strictly on this site-.specific
effect level, the soil invertebrate and plant effect levels
referenced in Eisler (chronic microbiota effects beginning at 375
mg/kg; acute earthworm effects at 150 to 165 mg/kg; reduced plant
productivity at 25 to 85 mg/kg), and the USEPA approved action
level (20 mg/kg, CIC report, page 2-4), it would appear to be
appropriate to conduct extensive removal activities in the off-site
stream area. Restoration would then return a low value habitat
that may improve over several decades. However, this area
-------
currently exist as a mature habitat corridor in an otherwise
heavily developed area. This increases the habitat value of this
area, indicating that destruction of this habitat should be
avoided. The increased value also increases the attraction of
receptors into this potentially hazardous habitat. Therefore, a
balance between the potential risk and the value of the habitat
roust be found.
It may be possible to affect a removal of the most grossly
contaminated surface soils, yet mitigate the impacts by minimizing
the areas to be removed. Using the graphical representation of the
contaminant levels present in Figure 3-8, it is possible to group
several sampling transects that contain the majority of the
contamination. Removal of these contaminated soils should
eliminate much of the potential risk, while attempting to minimize
the elimination of mature habitat. Sediments from Transects A and
B and surface soil from Transect A should be removed due to their
heavy contamination and low habitat value. These transects will
not be considered further in the data for this discussion.
Transects I through N and Transects V through AA (both six
transects, each approximately 700 to 900 feet in length) are
recommended for removal. Removal of these twelve of twenty-nine
transects (41%) eliminates significant contamination. The maximum,
mean., and median soil concentrations in Transects I through N,
Transects V though AA, and all remaining transects (excluding A and
B) are:
Transects: I - N V - AA . All remaining
Maximum 680.0 mg/kg 595.0'mg/kg 224.0 mg/kg
Mean 104.5 107.6 18.2
Median 39.2 55.1 10.5
This would eliminate twenty-eight of forty surface soil locations
(70%) containing levels exceeding 25 mg/kg. Extending the removal
of Transects I through N to include P (containing the 224 mg/kg
location) would reduce the maximum concentration of the remaining
transects to 88.4 mg/kg, and reduce the mean to 15.0.
Removing surface and deep sediments exceeding the Ontario
Guidelines (Persaud) from Transects I, K, and N would remove two of
the four elevated surface sediment locations, as well as -two of the
five deep locations. Leaving some of the adjoining excavated soil
areas unfilled may mitigate the threat of the transport of
remaining elevated surface sediments, and, reduce the potential for
storm events to scour, expose, and then transport remaining
elevated deep sediments. These small restorations of the flood
plain may help to restore wetland areas that allow for flood
storage. Thus, depending on the extent of excavation, this may
help reduce the energy in the stream flow during heavy storms.
We hope these comments have been helpful. If you have any
questions or comments, please feel free to contact us at (908) 417-
2238.

REMEDY FOR OFF-SITE AREAS
This community relations responsiveness summary is divided into
the following sections:
Overview; This section discusses the U.S. Environmental
Protection Agency's (EPA's) preferred alternative
for remedial action.
Background; This section briefly describes community relations
activities related to remediation of contaminated
soil and sediment in off-site areas associated
with the Chemical Insecticide Corporation (CIC)
site.
Summary of '
Comments; This section provides a summary of commentors'
major issues and concerns, and expressly
acknowledges and responds to all significant
comments raised by the local community. The local
community includes residents, businesses, the
municipality, public officials, and the Technical
Assistance Grant committee and its consultant.
OVERVIEW
At the initiation of the public comment period on November 7,
1994, EPA presented its preferred alternative for addressing
contaminated soil and sediment in residential areas and areas in
and immediately adjacent to the unnamed tributary and Hill Brook
associated with the CIC site, located in Edison Township, New
Jersey.
The selected remedy includes excavation and off-site disposal of
contaminated soil and sediment within particular areas along the
unnamed tributary and Mill Brook. In addition, contaminated soil
in a grassy area behind Building 14 of the Edison Glen
Condominium Complex will also be excavated for off-site disposal.
Approximately 10,000 cubic yards of soil and sediment will be
removed and the remediated areas will be appropriately restored.
This approach enables EPA to restore contaminated areas such that
any long-term risk associated with these areas is removed and no
property use restrictions will be required. By targeting
specific contaminated areas in and near the unnamed tributary and
Mill Brook, EPA is able to remove a large majority of the CIC
-------
contamination while achieving a reasonable and acceptable balance
in preserving a majority of the valuable ecology existing in
these areas.
COMMUNITY RELATIONS BACKGROUND
The Proposed Plan and supporting documentation for this second
cleanup phase associated with the CIC site were released to the
public for comment on November 7, 1994. These documents were
made available to the public in the administrative record
repositories maintained at the EPA Region II office (formerly, 26
Federal Plaza and currently 290 Broadway, New York, New York),
the Edison Township Municipal Complex (100 Municipal Boulevard,
Edison, New Jersey), the Edison Library (340 Plainfield Avenue,
Edison, New Jersey), and the Metuchen Library (480' Middlesex
Avenue, Metuchen, New Jersey) . A notice of availability for
these documents was published in The Star-Ledger on November 7,
1994. A public comment period involving the documents was held
from November 7, 1994 to December 7, 1994. In addition, a public
meeting was held on November 28, 1994, at the Edison Township
Municipal Building. At this meeting, representatives from EPA .
answered questions about the site and the remedial alternatives
under consideration. Responses to the comments received during
the comment period and at the public meeting are provided in this
Responsiveness Summary. ,
COMPREHENSIVE SUMMARY AND RESPONSES TO SIGNIFICANT COMMENTS
This section provides a comprehensive response to all significant
questions and comments raised by the local community during the
public meeting and received during the public comment period. .
A summary of these questions/comments and EPA's responses to them
is provided as follows:
1. A representative of the Edison Wetlands Association and the
Technical Assistance Grant (TAG) Committee's consultant
requested that EPA sample and analyze soil and sediment
further downstream in the Mill Brook, south of the
confluence of Mill Brook and the Nev Jersey Turnpike.
EPA Response: EPA agrees that additional sampling further
downstream is necessary to more accurately determine the
extent of contamination associated with the CIC site. EPA
plans to perform such additional sampling as part of the
remediation process for the areas in and around the unnamed
tributary and Mill Brook. This sampling will be conducted
during the first phase of remediation activities. If
necessary, additional areas will be designated for
remediation.
-------
2. A representative of the Edison Wetlands Association
requested that EPA provide access to the CIC site to perform
a dye test to more clearly define the surface water drainage
pathways leading from the site.
EPA Response: EPA understands that the Edison Department of
Health and Human Resources will provide the dye and
experienced personnel to perform the dye test. As EPA has
already stated at several recent Citizen's Advisory
Committee meetings, the Agency is willing to participate in
performing the dye test and providing supervised access to
the site.
3. A representative of the Edison Wetlands Association
requested that EPA evaluate a specific data point [510 parts
per billion (ppb) arsenic] generated by'a former owner of a
condominium in the Edison Glen Condominium Complex as a
result of sampling a puddle in the pool area of the complex.
EPA Response: EPA has evaluated the information provided by
the Edison Wetlands Association representative,. Based on
this evaluation, EPA believes that an arsenic level of 510
ppb in a puddle in the pool area can be attributed to the
naturally occurring levels of arsenic in soil. In addition,
EPA believes that risk associated with exposure to this
level of arsenic found in the puddled water would be
acceptable and similar to that posed by exposure to
naturally occurring arsenic levels [up to 20 parts per
million (ppm)] in New Jersey soil.
4. The TAG Committee's consultant and a representative of the
Edison Wetlands Association requested that EPA/ in
consultation with state and local government, the Edison
Wetlands Association and other stakeholders, consider
appropriate forms of institutional control (in addition to
the selected remedy) for the areas in and around the unnamed
tributary and Hill Brook.
EPA Response: EPA plans to use 20 ppm as a guideline in
remediating the contaminated soils and sediment in
residential areas and areas in and immediately adjacent to
the unnamed tributary and Mill Brook. Although this is not
a promulgated chemical-specific standard, and therefore not
an applicable or relevant and appropriate requirement, it
represents the upper limit of naturally occurring arsenic
concentrations in New Jersey soils. Use of this guideline
allows EPA to remove a large majority of the arsenic
contamination while achieving a reasonable and acceptable
balance in preserving a majority of the valuable ecology
existing in these areas.
Based on EPA's human health and ecological risk evaluation.
-------
the selected remedy is protective of human health and the
environment and EPA does not believe that any additional
institutional controls are warranted. In addition, because
the average residual level of arsenic is expected to be
below 20 ppm, the New Jersey Department of Environmental
Protection (NJDEP) does not require any land use
restrictions or form of institutional controls based on the
New Jersey Industrial Site Recovery Act.
The TAG Committee's consultant requested that EPA identify
the location of sample number 8SCG-6, questioned if this
location is part of one of the transects designated for
cleanup, and, if not, suggested that the area where this
sample vas obtained be added to the cleanup.
EPA Response: Sample number SSCG-6 designates a sediment
sample which was obtained from the most northern point of a
Mill Brook tributary running parallel to the southern edge
of the Edison Woods residential complex.
Although the concentrations detected at this location for
benzo(a)anthracene, benzo(b)flouranthene and benzo(a)pyrene
(2.6 ppm, 3.5 ppm, and 2.2 ppm, respectively) exceed NJDEP1 s
guidelines (as was indicated in the consultant's comment),
any risk posed by these contaminants would be insignificant
when compared to the risk posed by the primary contaminant
of concern, arsenic, and would not change EPA's overall
assessment of risk. Using the reasonable maximum exposure
scenario described in this Record of Decision (ROD), the
carcinogenic human health risk would remain within EPA's
acceptable risk range and any adverse non-carcinogenic
effects are still not likely to occur.
As is described in this ROD, the ecological risk assessment
indicates that adverse ecological effects are likely to
occur if no remedial action is taken. However, because the
Mill Brook and its tributaries currently exist as a mature
habitat corridor in an otherwise heavily developed area, the
habitat value of this area is increased and its destruction
should be avoided if possible. During the process of
selecting areas to be remediated and achieving a balance
between mitigating the potential risk to ecological
receptors and preserving the value of the area's ecosystem
(or minimizing destruction of the habitat through remedial
activity), EPA determined that the area where sample number
SSCG-6 was obtained does not require remediation.
-------
6. An attorney representing an owner of property located near
or within the area(s) designated for remediation submitted
to EPA written objection on behalf of the property owner to
any "egress and ingress onto their private property for the
purposes of a public cleanup of an adjacent or adjoining
property."
EPA Response: EPA may require future access to this
property for the purpose of remediating an adjacent or
adjoining property. A decision regarding access to this
property will be made during the planning phase of
implemention of the selected remedy. Each property owner
will be formally notified by EPA in a timely manner in
advance of the commencement of any field activities, a.nd
appropriate access arrangements will be made.
7. A representative of the community inquired about the adverse
effects of arsenic on the ecology and the food chain.
EPA Response: As is described in the ROD, the results of
the ecological risk assessment indicates that adverse
ecological effects primarily from arsenic are likely to
occur if no remedial action is taken. The results of soil
samples taken in the vicinity of the unnamed tributary and
Mill Brook indicate the presence of arsenic at levels
sufficient to generate acute risk to soil invertibrates and
chronic risk to soil microbiota and small mammals. In
addition, surficial stream sediments in some areas along the
unnamed tributary and Mill Brook contain sufficient arsenic
to pose a risk to the benthic community. Risk to organisms
at higher trophic levels, via exposure through the food chain
was also assessed. It was determined that no risk to such
organisms via this pathway of exposure is anticipated.
8. A representative of Congressman Pallone's office inquired
about the process for cleaning the surface water, how far
downstream EPA is willing to test and how EPA expects to
actually clean up the areas in and around the unnamed
tributary and Mill Brook.
EPA Response: Although the selected remedy does not include
active measures to clean the surface water, EPA believes
that removal of contaminated soils and sediment will
contribute to the improvement of surface water quality in
the unnamed tributary and Mill Brook. The surficial cap
which was recently installed at the QIC site will also
contribute to the improvement of surface water quality by
controlling the release of contaminated surface water runoff
from the site.
EPA agrees that additional sampling further downstream is
necessary to more accurately determine the extent of
-------
contamination associated with the CIC site. A determination
as to the extent of downstream sampling will be made based
on an evaluation of sampling data. After collection of
additional data, the results will be evaluated, along with
existing data, to assess potential impacts to human health
and the environment.
The cleanup of the unnamed tributary and Mill Brook will
include excavation of contaminated soil and sediment and
appropriate disposal of such material in a secure off-site
landfill. Heavy equipment such as bulldozers, backhoes and
dump trucks are expected to be used for the remediation.
Temporary access roadways will be constructed to provide
vehicular equipment access to areas to be remediated. EPA
intends to minimize .tree removal during the remedial
activities. The Agency will work closely with the community
during the remedial design phase to coordinate construction
activities.
9. A concerned citizen inquired about the location of the off-
site disposal facility, the method for remediating the
contaminated soil (if incineration would be the remediation
method) and if EPA would be using a particular stone to
stabilise the remediated banks of the unnamed tributary and
Mill Brook.
EPA Response: The location of the off-site disposal
facility has not yet been selected. A secure off-site
disposal facility will be identified prior to commencement
of excavation activities. The contaminated material will be
appropriately landfilled at the selected off-site facility.
The material will not be incinerated. Depending on the
material's ultimate waste classification prior to
landfill ing, some pretreatment (i.e., solidification) may be
necessary before landfilling. If necessary, this would be
performed at the off-site disposal facility.
During the restoration of the remediated areas in and along
the unnamed tributary and Mill Brook, EPA will also
stabilize the banks of these waterways. Stone may be used
as a stabilizing material. The stabilization method(s) will
be identified during the planning phase of the remediation.
10. A concerned citizen asked if EPA could repeat surface water
sampling in the Spring of 1995 to assure that the cap over
the CIC site has eliminated contaminated surface water
runoff.
EPA Response: EPA does not believe that sampling the
surface water and determining its quality will be indicative
that the cap is fully working. Therefore, EPA does not plan
to sample surface water to determine the effectiveness of
-------
the cap. EPA believes that maintaining the integrity of the
cap will assure that the cap continues to accomplish its
intended goal, to control contaminated surface water runoff
from the site. EPA will perform periodic site inspections
and make any necessary repairs of the interim remedy (the
cap and all its other components) to preserve the integrity
of the remedy and ensure that rainwater or surface runoff
does not contact contaminated materials on-site
11. A concerned citizen inquired about the maximum depth of soil
and sediment sampling, the depth of arsenic contamination,
and if an arsenic concentration gradient was established
with depth of soil/sediment.
EPA Response: During EPA's investigation, soil/sediment
samples were obtained at a maximum sample 'depth of 30-36
inches. Arsenic contamination was observed at the maximum
soil depth sampled. Based on an evaluation of the data, EPA
could not establish a clear relationship between soil depth
and arsenic levels. In some instances, the arsenic levels
increased with soil depth and in others, it decreased with
depth.
12. A concerned citizen encouraged EPA to minimize disruption of
the ecology in the areas of the unnamed tributary and Kill
. Brook by sampling and analyzing soil as the excavation
activities proceed.' The citizen recommended that areas
which are confirmed clean can be left alone.
EPA Response: EPA agrees. In fact, EPA applies this
process of sampling and analyzing soil during an excavation
remedy as a standard operating procedure, and will minimize
disruption to areas not requiring .remediation.
13. A concerned citizen requested that EPA provide a landscaping
plan which identifies which trees will be saved during
implementation of the remedy and that any wetlands impacted!
by the remediation be restored.
EPA Response: EPA intends to minimize tree removal during
the remedial activities. EPA plans to work closely with the
community during the remedial design phase and to coordinate
construction activities so that the community is kept fully
informed. EPA will identify certain areas requiring tree
removal (such as those areas where temporary access roadways
will be constructed) prior to commencement of excavation
activities. Other areas requiring tree removal will be
identified during the excavation activities under EPA
supervision.
Wetland areas disrupted by the remedial activities will be
appropriately restored.

14. An Edison Councilman questioned why EPA ceased sampling
immediately south of the confluence of Mill Brook and the
New Jersey Turnpike by the Edison Woods residential complex
and whether there is a concern about the potential for
contaminated groundwater to continue to migrate and
contaminate the waterways targeted for remediation.
EPA Response: EPA's standard operating procedure for
performing field investigations is to take a phased sampling
approach. An initial plan is developed targeting specific
areas to be sampled. Based on the results of the initial
sampling program, a determination regarding the need for
additional sampling is made. In this .case, additional
sampling further downstream is necessary to more accurately
determine the extent of contamination associated with the
CIC site. EPA plans to perform such additional sampling as
part of the remediation process for the areas in and around
the unnamed tributary and Hill Brook.
Although contaminated groundwater may be discharging into
the waterways designated for remediation, EPA does not
believe that the groundwater is contaminated at levels which
could contaminate soil and sediment to levels of concern.
EPA believes that the contamination requiring remediation in
these areas has resulted primarily from historical
contaminated surface water runoff, discharged from the CIC
site over the long period prior to the installation of the
cap over the site. EPA further believes that the
contribution, if any, of contaminated groundwater to the
contamination in the areas to be remediated is
insignificant.
15. A concerned citizen inquired about the naturally occurring
level of arsenic in soil, the arsenic level which is deemed
to be acceptable in groundwater and whether certain forms of
arsenic are more harmful than others.
EPA Response: NJDEP has determined the upper limit of
naturally occurring arsenic for New Jersey soils to be 20
ppm. The Federal acceptable drinking water level for
arsenic is 50 ppb.
The arsenic that occurs naturally may occur in different
forms with different toxicities or degrees of potential harm
to human health and the environment. During EPA's risk
assessment process, the Agency assumes that arsenic is in
its most harmful or toxic form, thereby providing an
additional level of assurance regarding protection of human
and the environment.

16. A representative of the Edison Wetlands association
requested access to data which may b« generated from
resampling the property adjacent to Prince street/ in
Edison, Hew Jersey/ during the course of remediation. The
representative also asked if a developer sampled the
property and found higher arsenic levels/ vould EPA review
the area?
EPA Response: Although EPA does not anticipate further
sampling of the subject property at this time, if EPA should
generate any future data from resampling the property, the
Agency would make it available for review.
If EPA were presented with data which conflicted with data
the Agency collected, EPA would investigate and evaluate the
situation further.
17. A concerned citizen asked whether the approximately 10% of
total soil and sediment samples which were analyzed for
other contaminants/ including arsenic/ were randomly
selected and whether any of these samples were taken on
Wayne Miller*s former property?
EPA Response: These samples and their locations were
randomly selected but were obtained from each of the four
general areas which were sampled (Edison Glen, Edison Woods,
Rodak Circle/Wilshire Road and the unnamed tributary/Mill
Brook areas).
During EPA's most recent sampling effort, samples of this
kind were obtained on or in the immediate vicinity of the
property formerly owned by Wayne Miller. Similar samples
have also been obtained from this property during previous
EPA investigations.
18. A concerned citizen asked when the remediation activities
would begin?
EPA Response: Based on EPA's ability to secure a contractor
in a timely fashion, EPA believes that the remediation
activities will commence during the Spring of 1995.
