The document provides site summaries for 4 locations in New Jersey - the DuPont & Company site, Maywood Chemical Works, Middlesex Sampling Plant, and Princeton Plasma Physics Laboratory. It describes the historical activities at each site, the contaminants present, and notes that the U.S. Army Corps of Engineers is responsible for remediation at these Formerly Utilized Sites Remedial Action Program sites, while the U.S. Department of Energy is responsible for any long-term stewardship activities once cleanup is complete. However, the document notes that cleanup is not yet finalized at these sites so the extent of required long-term stewardship is not yet determined.

DUPONT & COMPANY 1
SITE SUMMARY
The DuPont & Company site (also known as the DuPont Chambers Dye Works) is located in the Townships of
Pennsville and Penns Grove on the southeastern shore of the Delaware River and is adjacent to the residential
community of Deepwater, New Jersey. The site is bordered on the north by a DuPont property (the Carneys
Works), on the east by U.S. Route 130, on the south by Salem Canal, and on the west by the Delaware River.
During the 1940s E.I. DuPont de Nemours & Company (DuPont) produced uranium products and conducted
research on uranium hexafluoride in three buildings at the site. These activities were conducted first for the U.S.
Office of Scientific Research and Development and later under contract to the Manhattan Engineer District and
the Atomic Energy Commission (AEC), predecessor agencies of the U.S. Department of Energy (DOE). The
activities that DuPont conducted in support of these contracts resulted in the contamination of onsite buildings
and soil and generated radiological waste. After these activities ceased, all the contaminated equipment were
removed and taken to the AEC portion of the Lake Ontario Ordnance Works in Lewiston, NY. Building
decontamination was conducted in 1948 under the direction ofthe AEC. A radiation survey was then conducted
by the AEC, and the buildings were subsequently released to DuPont.
A further survey in 1977 found elevated levels of uranium in Building 845, where uranium peroxide was
produced, and in surface and subsurface soils. This led to the DuPont & Company Site's inclusion in the

7. Maywood Chemical Works
MAYWOOD CHEMICAL WORKS 1
SITE SUMMARY
The areas comprising the Maywood Chemical Works Site are located in a highly developed area of Bergen
County that includes residential, commercial, and municipal property in the Boroughs ofMaywood and Lodi and
the Township ofRochelle ParkinNew Jersey. The Maywood Chemical Works Site includes the following areas:
(1) the Maywood Interim Storage Site; (2) the Stepan property, an active chemical plant; and (3) about 80
residential, commercial and governmental properties in Maywood, Lodi, and Rochelle Park. The Maywood
Interim Storage Site is bordered by State Route 17 on the west, the New YorkSusquehanna and Western Railroad
line on the north, and commercial and industrial properties on the south and east.
From 1916 to 1956, Maywood Chemical Works extracted thorium and rare earth elements from monazite sands
for use in commercial products. During the operation of this plant, radioactive waste migrated or was moved
offsite and contaminated the surrounding areas. Contamination spread via the former Lodi Brook, which ran
south past the site and into the Borough of Lodi. Thorium waste in the brook settled onto properties along its
path where commercial buildings and residential houses were later built. Wastes were also used as fill or mulch
around the area.
Stepan Company acquired the Maywood Chemical Works in the late 1950s. The company began cleaning up
the residual thorium waste by partially stabilizing the residues and tailings. During the 1960s, Stepan Company

transferred contaminated material from one area of the site to burial pits on the Stepan property.
In the 1980s, radioactive materials were discovered in the northeastern corner of the site. Subsequent surveys
indicated that the contamination extended beyond site boundaries and, consequently, several residential vicinity
properties required remediation. The primary radioactive contaminants are thorium232 and its decay products,
as well as uranium and radium226. The primary chemical contaminants are heavy metals and rare earth
elements. The risk to the public from these contaminants is minimal. Concentrations are generally low and much
of the material is inaccessible (subsurface or beneath structures).
The Maywood Site was added to the Environmental Protection Agency's National Priorities List. At the
direction of Congress in the 1984 Energy and Water Development Appropriations Act, the site was designated
for cleanup under the Formerly Utilized Sites Remedial Action Program (FUSRAP). Additionally, a
Memorandum ofUnderstanding was signed between DOE and the Borough ofMaywood in the 1980s concerning
the removal of the Maywood Interim Storage Pile. The Corps' remedial action for the Maywood Chemical
Works Site is not yet complete and, therefore, the extent of long-term stewardship required, if any, is not yet
known.

9. Middlesex Sampling Plant
MIDDLESEX SAMPLING PLANT 1
SITE SUMMARY
The Middlesex Sampling Plant is located in the Borough of Middlesex in New Jersey, approximately 56
kilometers (35 miles) northeast of Trenton and 42 kilometers (26 miles) southwest of Newark. The site is
bordered on the east by residential properties on Mountain Avenue, on the south by William Street, and on the
north by the Lehigh Valley Railroad line.
In the 1940s, the Manhattan Engineer District (MED), an early predecessor agency to the U.S. Department of
Energy (DOE), established the Middlesex Sampling Plant to sample, store, and ship uranium and thorium ores.
When MED operations at the site ceased in 1955, the Atomic Energy Commission (AEC), the successor agency
to the MED and a predecessor agency to DOE, used this site to store and sample thorium. In the 1960s,
operations at the Middlesex Sampling Plant were terminated and all remaining thorium sampling activities were
transferred to the Feed Materials Production Center and to the Weldon Spring Plant.
The activities that took place at the site during the 1950s and 1960s contaminated not only onsite soil and
facilities but also vicinity properties and a nearby municipal landfill. Primary contaminants at the site include
uranium, radium, thorium, lead, and organics.

When ABC activities were terminated, onsite structures were decontaminated to levels that met the current
standards. From the late 1960s until the late 1970s, the site was used by the U.S. Marine Corps. In 1978, the
DOE assumed custody of the site and the site was designated for cleanup under the Formerly Utilized Sites

PRINCETON PLASMA PHYSICS LABORATORY
1.0 SITE SUMMARY
1.1 Site Description and Mission
The Princeton Plasma Physics Laboratory is a
Collaborative National Center for plasma and fusion
science. The Laboratory is located on 36 hectares (88.5
acres) of property leased from Princeton University on
the James Forrestal Campus, in Plainsboro Township,
Middlesex County, New Jersey. The Laboratory
operates several devices, including the National
Spherical Torus Experiment on Princeton University's
campus. The Tokamak Fusion Test Reactor, which
achieved world-record energy output, is currently
undergoing dismantlement and will be completed by
2003. Other site facilities include maintenance shops,
warehouses, transformer yards, storage buildings,
administrative offices, educational facilities, and

Princeton University expires in 2026, unless DOE decides to terminate it earlier.
DOE's lease with
The Princeton Plasma Physics Laboratory's primary mission is to conduct research and development of nuclear
fusion technology as an attractive energy source. The Laboratory also historically provided research and
development for fusion energy programs sponsored by DOE and its predecessor agencies. Research at the
Laboratory began in 1959 with construction of the Model C-Stellerator, which was later converted to a pulse-
operated device. Past activities and operations contaminated the soil and groundwater at the site with volatile
organic compounds (petroleum, hydrocarbons, and solvents). All site remediation activities have been completed
for soil, allowing unrestricted use ofthe site (with respect to soil). Groundwater in the shallow aquifer along the
southern portion of the site, which comprises a surface area of about 12 hectares (30 acres), contains relatively
low levels of chlorinated volatile organic compounds.
The Laboratory continues to generate waste, including oils, solvents, polychlorinated biphenyls, and low-level
radioactive wastes. Waste is neither treated nor disposed of onsite, but it is collected in satellite accumulation
areas before it is transferred to offsite locations. Hazardous waste is sent to commercial facilities, and low-level
radioactive waste is shipped to other DOE sites for disposal.
1.2 Site Cleanup and Accomplishments
DOE completed soil remediation activities at Site C/D on the university campus in 1999. Soil contamination
consisted of chromium (a heavy metal) and oil-related organic compounds. Approximately 153 cubic meters
(200 cubic yards) of the metal-contaminated soil were excavated and disposed of at a commercial facility
permitted to accept hazardous waste. Approximately 30 cubic meters (40 cubic yards) oforganics-contaminated
soil were removed and disposed offsite. All contaminated soils were remediated to cleanup standards dictated
by the New Jersey Department of Environmental Protection. In 2000, the New Jersey Department of
Environmental Protection released the site (with respect to soil) for unrestricted use under a "No Further Action
Determination." Because of the success of the soil removal actions, and the full characterization of the soils
throughout the site, long-term monitoring of the soil is not required.

The single medium of concern that remains at the site is the groundwater contamination within the shallow
aquifer, which most likely resulted from surface spills of solvents. This medium will require long-term
stewardship activities.
All surface water from the building sumps is discharged into a lined stormwater detention basin, which
discharges into a nearby brook. The discharge to the brook is routinely monitored in compliance with a State
of New Jersey surface water discharge permit. Because of the natural degradation of the volatile organic
compounds within the aquifer, dilution, and volatilization, residual volatile organic compounds are below the
regulatory discharge limit to the brook. If volatile organic compounds levels in the discharge rise in the future,
mitigation measures may be necessary.

13. 2.0 SITE·WIDE LONG·TERM STEWARDSHIP
2.1 Site-Wide Long-Term Stewardship Activities
Because of the contamination resulting from past
operations, long-term stewardship activities will be
required at the Princeton Plasma Physics Laboratory.
These activities, for the most part, will involve
groundwater monitoring and surveillance to prevent
contaminants from migrating offsite. Currently, DOE
anticipates monitoring will continue until 2010. Soils
are not subject to long-term stewardship activities since
they have been remediated to acceptable levels and the
site is no longer restricted for use.
No institutional controls are required under the "No
Further Action Determination" issued by the New
Jersey Department of Environmental Protection.
However, because DOE leases the 36 hectares (88.5
acres) of property from Princeton University, DOE is
bound by the terms of the lease agreement to return the
property to Princeton University free from
environmental hazards.
The New Jersey Department of Environmental
Protection will implement an institutional control
designated as a "classification exception area" for the
contaminated groundwater plume at the Laboratory.
The "classification exception area" functions as a deed
restriction on groundwater at the site, preventing its
unauthorized use. The "classification exception area"

soil. Added six above-ground, secondarily-
confined tanks (1989-1993)
• Installed impermeable line in retention basin for
collecting onsite surface water and groundwater
from building dewatering sumps (1995)
• Completed two soil removal actions: 153 cubic

• Baseline ecological evaluation found no evidence
of impacts to vegetation or wildlife attributable to
onsite environmental conditions (1998)
• All identified areas of concern (10) for soil

no further action issued by State of New Jersey for
soil (2000)
ANTICIPATED SITE
ACCOMPLISHMENTS AS OF 2006
• Princeton Plasma Physics Laboratory will continue
to monitor the natural attenuation of groundwater
contaminants at least until2010
designation also provides regulatory relief, allowing groundwater contaminants to naturally andpassively degrade
until the statewide groundwater quality standards are met. Because soil contamination is no longer present at
levels above New Jersey Department of Environmental Protection standards and the low levels of groundwater
contamination are inaccessible to human contact, exposure to site workers or the public is not a concern. In
addition, a baseline ecological evaluation conducted during a site remedial investigation found no adverse
environmental impacts from the groundwater contamination. As a result, the site does not require any special
physical barriers (e.g., fences) or visual warnings (e.g., signs).
Record-keeping activities are required under a Memorandum of Understanding between Princeton University
and the New Jersey Department of Environmental Protection, which governed the cleanup activities at the
Laboratory. The Laboratory is currently required to maintain all characterization, remediation and monitoring
records for a minium of 30 years. In addition, the Laboratory also maintains a public information repository in
which copies of applicable remedial investigation
documents are kept.

monitoring wells. This technology consists of small air- driven bladder pumps located at the bottom ofeach well
that gently purges the well water while analyzing various groundwater parameters (e.g., temperature,
alkalinity/acidity, redox). Once the parameters have stabilized, a groundwater sample is taken. As a result, the
depiction of actual groundwater conditions are more precise, and less waste water is generated during the well
purging process. Utilization of this technology will continue for the duration of the long-term stewardship
monitoring program.
2.2 Specific Long-Term Stewardship Activities
Groundwater
The single medium of concern that remains at the site is the groundwater contamination within the shallow
aquifer, which most likely resulted from past surface spills of chlorinated solvents. The remediation strategy
applied to the volatile organic compounds and petroleum (and approved by the New Jersey Department of
Environmental Protection) is hydraulic control of migration with existing building dewatering pumps,
monitoring, and natural attenuation. This remedy- referred to as "hydraulic groundwater control"- will keep
contaminants from migrating offsite while chlorinated volatile organic compounds are allowed to naturally
degrade within the aquifer. At this time, no engineered groundwater treatment system is required. The progress
of natural attenuation will be monitored by quarterly groundwater sampling until New Jersey water quality
standards are met. Target cleanup levels are one part per billion for tetrachloroethene, trichlorethene, 1,1,1-
trichloroethane, and dichloroethenes under New Jersey groundwater quality standards.
Approximately 12 hectares (30 acres), with an average saturated thickness ofnine meters (30 feet), ofthe aquifer
on the southern boundary of the site is contaminated above New Jersey water standards. This equates to
approximately 189,270cubic meters (247,556 cubic yards) ofcontaminated groundwater. Monitoring is required
to document the selected remedy of hydraulic control and natural contaminant attenuation.
2.3 Regulatory Regime
Long-term stewardship activities of the Princeton Plasma Physics Laboratory are governed by the New Jersey
Department of Environmental Protection pursuant to the Administrative Code of the New Jersey Technical
Requirements for Site Remediation. This regulatory requirement is executed in accordance with a Memorandum
ofUnderstanding (Feb. 3, 1993) between Princeton University and theNew JerseyDepartment ofEnvironmental
Protection for the remediating Site C and D of the James Forrestal Campus. The MOU acknowledges that Site
CID is leased by DOE and that DOE contracts with Princeton University to manage and operate the Laboratory.
A letter issued by the Department's Bureau of Case Management on March 17, 2000, approved the Remedial
Investigation/Remedial Action Selection Report and approved the proposed groundwater remedy of hydraulic
containment and natural attenuation.
All long-term stewardship activities exclusively address the groundwater at the Laboratory. A No FurtherAction
Letter and Covenant Not to Sue for the soil at Princeton was signed by the New Jersey Department of
Environmental Protection and Princeton University on March 28, 2000. No long-term stewardship activities are
required for the soils at the Princeton Plasma Physics Laboratory. Because the long-term remedial activity at the
Princeton Plasma Physic Laboratory consists only of the continuation of groundwater monitoring, no additional
remedial systems are identified or required at this time. Therefore, a review under the National Environmental
Policy Act of 1969, as amended, is not applicable and no hazardous or low-level radioactive waste will be
generated as a result of the selected long-term stewardship activities.
New Jersey 12

15. Princeton Plasma Physics Labomtory
2.4 Assumptions and Uncertainties
The long-term surveillance and monitoring of the groundwater contamination is assumed to consist of quarterly
monitoring for at least 10 years until 2010. No further actions will be required. Princeton Plasma Physics
Laboratory will continue to operate as a national laboratory for energy research. Therefore, future use of this
facility will remain industrial.
3.0 ESTIMATED LONG·TERM STEWARDSHIP COSTS
The estimated costs for long-term stewardship activities at the Princeton PlasmaPhysics Laboratory are identified
in the table below. The annual site-wide cost estimate for long-term stewardship activities is approximately
$280,000 per year for the period of fiscal years (FY) 2000-2010. An annual budget of $273,000 (in FY 1999)
dollars supported the quarterly groundwater collection and analysis, general maintenance of monitoring wells,
administrative reporting and record-keeping. Beginning in FY 2001, these costs and responsibilities will be
transferred from DOE's Office of Environmental Management to DOE's Office of Science.

4.0 FUTURE USES
The Princeton Plasma Physics Laboratory will continue to operate as a national laboratory conducting research
in plasma science and fusion energy. Therefore, future use of this facility will remain industrial - as a
commercial/research property consistent with past use. With respect to soil contamination, unrestricted use is
allowed. The Laboratory and all surrounding properties receive potable water from the public water utility. The
Laboratory uses the nearby Delaware and Raritan Canal for process cooling water. The onsite water supply wells
are available only for backup firefighting purposes and are not used for potable purposes. As a result, the existing
groundwater contamination has not affected the existing land use as a "commercial/research property." If the
Laboratory's lease expires in 2026 without renewal, or is terminated prior to expiration, DOE is bound by the
lease agreement to return the property free of environmental hazards.

17. Wayne Site
WAYNE SITE I
SITE SUMMARY
The Wayne Site is located about 3.2 kilometers (two miles) north of Wayne, New Jersey, in a highly developed
area of Passaic County. The site is approximately 58 kilometers (36 miles) northwest of New York City.
Between 1948 and 1971, Rare Earths, Inc., and its successor, W.R. Grace and Company, processed monazite
sands to recover thorium and other rare earth elements. In 1955, under a contract issued by the Atomic Energy
Commission (AEC), a predecessor agency to the U.S. Department of Energy (DOE), the company began to
process Government-owned thorium ores for the AEC (ABC-funded thoriumprocessing may have begun as early
as 1948). The contract was terminated in 1960. Thereafter, W.R. Grace and Co. processed monazite sands for
commercial purposes until 1971. Between 1967 and 1984, the property was leased to and occupied by Electro-
Nucleonics, Inc.
Prior to 1960, radioactive residues from the processing of thorium ores were placed in above-ground piles. From
1960 to 1967, the thorium wastes were buried-- sometime between 1960 and 1964, they were buried in large
unlined pits. In 1965, the material was exhumed and buried in smaller pits. From 1967 to 1971, thorium
phosphate wastes were shipped to the W.R. Grace and Co. plant in Chattanooga, Tennessee.
Liquid wastes were neutralized in an onsite treatment plant and released into the storm water sewer system,
which discharges into Sheffield Brook and, eventually, into the Pompton River. In 1971, at the request ofW.R.
Grace and Co., AEC modified the W.R. Grace license to allow only storage.

18. National Defense Authorization Act (NDAA) Long-lerm Stewardship Report
After plant operations ceased in 1971, W.R. Grace and Co. partially decontaminated the site. In addition to
covering an onsite disposal area with clean fill, the company razed several buildings and buried the resulting
rubble and processing equipment in place. The remaining buildings were decontaminated and left intact.
The primary contaminants of concern are thorium and radium and their daughter products. Tailings migrated
offsite via Sheffield Brook and contaminated vicinity properties. Areas surrounding the railroad spur in nearby
Pequannock, where thorium-containing ores were unloaded, were also contaminated. Cleanup has been
completed and certified at most of the designated vicinity properties. Radioactive residues from the vicinity
property cleanup are in interim storage on the site.
The Wayne Site is on the U.S. Environmental Protection Agency (EPA) National Priorities List and is also the
subject of a Federal Facilities Agreement between U.S. Department of Energy (DOE) and EPA. In 1983,
Congress authorized the cleanup of the Wayne Site under the Formerly Utilized Site Remediation Action
Program (FUSRAP). In September of 1984, the Wayne Site was donated to DOE. The Corps' remedial action
for the site is not yet complete and, therefore, the extent of long-term stewardship required, if any, is not yet
known.
