National Oil and Hazardous Substances Pollution Contingency Plan;
National Priorities List: Deletion of the W.R. Grace & Co., Inc./Wayne
Interim Storage (USDOE) Superfund Site
AGENCY: Environmental Protection Agency.
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) Region II is
publishing a direct final Notice of Deletion of the W.R. Grace & Co.,
Inc./Wayne Interim Storage (USDOE) Superfund Site (the Site), located
at 868 Black Oak Ridge Road, Wayne Township, NJ 07470, from the
National Priorities List (NPL). The NPL, promulgated pursuant to
section 105 of the Comprehensive Environmental Response, Compensation,
and Liability Act (CERCLA) of 1980, as amended, is an appendix of the
National Oil and Hazardous Substances Pollution Contingency Plan (NCP).
This direct final deletion is being published by EPA with the
concurrence of the State of New Jersey, through the Department of
Environmental Protection, because EPA has determined that all
appropriate response actions under CERCLA, have been completed.
However, this deletion does not preclude future actions under
Superfund.
DATES: This direct final deletion is effective on September 30, 2012,
unless EPA receives adverse comments by September 19, 2012. If adverse
comments are received, EPA will publish a timely withdrawal of the
direct final deletion in the Federal Register informing the public that
the deletion will not take effect.

V. Deletion Action
I. Introduction
EPA Region II is publishing this direct final Notice of Deletion of
the Site, from the NPL The NPL constitutes Appendix B of 40 CFR part
300, which is the NCP, which EPA promulgated pursuant to section 105 of
CERCLA, as amended. EPA maintains the NPL as the list of sites that
appear to present a significant risk to public health, welfare, or the
environment. Sites on the NPL may be the subject of remedial actions
financed by the Hazardous Substance Superfund (Fund). As described in
300.425(e)(3) of the NCP, sites deleted from the NPL remain eligible
for Fund-financed remedial actions if future conditions warrant such
actions.
Because EPA considers this action to be noncontroversial and
routine, this action will be effective on September 30, 2012, unless
EPA receives adverse comments by September 19, 2012. Along with this
direct final Notice of Deletion, EPA is co-publishing a Notice of
Intent To Delete in the ``Proposed Rules'' section of the Federal
Register. If adverse comments are received within the 30-day public
comment period on this deletion action, EPA will publish a
[[Page 50045]]
timely withdrawal of this direct final Notice of Deletion before the
effective date of the deletion, and the deletion will not take effect.
EPA will, as appropriate, prepare a response to comments and continue
with the deletion process on the basis of the Notice of Intent To
Delete and the comments already received. There will be no additional
opportunity to comment.
Section II of this document explains the criteria for deleting
sites from the NPL. Section III discusses procedures that EPA is using
for this action. Section IV discusses the Site and demonstrates how it
meets the deletion criteria. Section V discusses EPA's action to delete
the Site from the NPL unless adverse comments are received during the
public comment period.
II. NPL Deletion Criteria
The NCP establishes the criteria that EPA uses to delete sites from
the NPL. In accordance with 40 CFR 300.425(e), sites may be deleted
from the NPL where no further response is appropriate. In making such a
determination pursuant to 40 CFR 300.425(e), EPA will consider, in
consultation with the state, whether any of the following criteria have
been met:
i. Responsible parties or other persons have implemented all
appropriate response actions required;
ii. All appropriate Fund-financed response under CERCLA has been
implemented, and no further response action by responsible parties is
appropriate; or
iii. The remedial investigation has shown that the release poses no
significant threat to public health or the environment and, therefore,
the taking of remedial measures is not appropriate.
III. Deletion Procedures
The following procedures apply to deletion of the Site:
(1) EPA consulted with the State of New Jersey prior to developing
this direct final Notice of Deletion and the Notice of Intent to Delete
co-published today in the ``Proposed Rules'' section of the Federal
Register.
(2) EPA has provided the State 30 working days for review of this
notice and the parallel Notice of Intent to Delete prior to their
publication today, and the state, through the Department of
Environmental Protection, has concurred on the deletion of the Site
from the NPL.
(3) Concurrently with the publication of this direct final Notice
of Deletion, a notice of the availability of the parallel Notice of
Intent to Delete is being published in a major local newspaper, The
North Jersey Herald & News. The newspaper notice announces the 30-day
public comment period concerning the Notice of Intent to Delete the
Site from the NPL.
(4) The EPA placed copies of documents supporting the proposed
deletion in the deletion docket and made these items available for
public inspection and copying at the Site information repositories
identified above.
(5) If adverse comments are received within the 30-day public
comment period on this deletion action, EPA will publish a timely
notice of withdrawal of this direct final Notice of Deletion before its
effective date and will prepare a response to comments and continue
with the deletion process on the basis of the Notice of Intent to
Delete and the comments already received.
Deletion of a site from the NPL does not itself create, alter, or
revoke any individual's rights or obligations. Deletion of a site from
the NPL does not in any way alter EPA's right to take enforcement
actions, as appropriate. The NPL is designed primarily for
informational purposes and to assist EPA management. Section
300.425(e)(3) of the NCP states that the deletion of a site from the
NPL does not preclude eligibility for future response actions, should
future conditions warrant such actions.
IV. Basis for Site Deletion
The following information provides EPA's rationale for deleting the
W.R Grace & Co., Inc./Wayne Interim Storage (USDOE) Superfund Site (the
Site) from the NPL:
Site Background and History
The Site is approximately 6.5 acres located at 868 Black Oak Ridge
Road at the intersection with Pompton Plains Cross Road in Wayne
Township, Passaic County, New Jersey. The Vicinity Properties (VPs) are
commercial and residential areas, and a Township Park, all located
within one-half mile to the west and west-southwest of the Site which
were affected by contaminant migration from the Site along Sheffield
Brook, which flows downstream to the Pompton River. The Site is in a
highly developed area of northern New Jersey, approximately 20 miles
north-northwest of Newark, New Jersey. The Site CERCLIS ID Number is
NJ1891837980.
From 1948 through 1957, Rare Earths, Inc. processed monazite sand
at the Site to extract thorium and rare earth metals. The Davison
Chemical Division of W.R. Grace acquired the Site in 1957 and
processing activities continued until July 1971. After processing
ceased in 1971, the facility was licensed by the Atomic Energy
Commission (AEC) for storage only. In 1974, W.R. Grace partially
decontaminated the Site. Some buildings were razed and the rubble and
processing equipment were buried on the property.
In 1974, the Nuclear Regulatory Commission (NRC) assumed licensing
responsibilities formerly held by the AEC. In 1975, the storage license
for radioactive materials was terminated by the NRC following Site
decommissioning and the Site was released without radiological
restriction; the only stipulation was that the property deed state that
radioactive materials were buried on the property.
In 1981, as part of the review of formerly licensed facilities, the
NRC measured direct radiation levels and radionuclide concentrations in
soil on the Site. Elevated survey measurements were noted, indicating
the Site was contaminated with radium (Ra)-226, thorium (Th)-232, and
uranium (U)-238, and associated daughter products. The chemical
contaminants of concern (COC) are antimony, arsenic, chromium, lead,
mercury, molybdenum, and thallium.
In July 1983, the U.S. Department of Energy (USDOE) was authorized
by the Energy and Water Development Appropriations Act of 1984 to
conduct a decontamination research and development project at the Site.
From 1984 to October 1997, the USDOE managed the Site under the
Formerly Utilized Sites Remedial Action Program (FUSRAP). The Site was
proposed to the NPL on September 8, 1983, (48 FR 40674). The Site was
included on the NPL on September 21, 1984 (49 FR 37070). In September
1985, ownership of the Site transferred from W.R. Grace & Co. to the
U.S. Government.
In July 1990, the USDOE signed a Federal Facility Agreement (FFA)
that established cleanup responsibilities under CERCLA. The FFA was
signed by the EPA in September 1990.
In October 1997, Congress transferred administration and execution
of the FUSRAP program from the USDOE to the U.S. Army Corps of
Engineers (USACE) in the Energy and Water Development Appropriations
Act of 1998. In March 1998, the original USDOE/EPA Site FFA was
renegotiated between EPA and the USACE.
Between 1985 and 1987, the USDOE conducted removal actions to
remove contaminated material from some of the off-site VP locations in
the vicinity of the Site. The adjacent VPs had received contaminants
during historical W.R. Grace processing operations, which required
remediation. Excavated soils
[[Page 50046]]
and debris were stored at the Site where the historic thorium
processing operations occurred because no disposal facilities were
available which were licensed or permitted to accept radiological
wastes at the time. These actions were outlined in the Action
Description Memorandum, Proposed FY 1984 Remedial Actions at Wayne, New
Jersey (1984).
During 1993, removal actions at the remaining Site VPs were
conducted under the Engineering Evaluation/Cost Analysis (EE/CA) for
the Proposed Removal of Contaminated Materials from Vicinity Properties
at the Wayne Site (1993). The majority of the waste from the 1993
cleanup actions was shipped directly to a commercial disposal facility.
A small amount of contaminated soil from the 1993 cleanup actions was
added to the interim storage pile at the Site due to off-site waste
disposal constraints in effect at the time.
For the VPs surrounding the Site, the USDOE implemented residual
contamination guidelines governing the release of formerly contaminated
property for unrestricted use. The DOE Guidelines for Residual
Radioactivity at FUSRAP and Remote SPMP Sites (1985), provided the
following guidelines:
External gamma radiation levels on a site released for
unrestricted use to not exceed 20 microRems/hour above the ground
surface;
Maximum permissible concentration of Ra-226 and Th-232 in
soil above background levels averaged over 100 cubic meters; 5
picoCuries/gram (pCi/g) averaged over the first 15 centimeters (cm) of
soil at the surface; 15 pCi/g when averaged over 15-cm thick soil
layers more than 15 cm below the surface (i.e., for sub-surface soils
at depths greater than 15 cm); and,
Maximum permissible concentration of U-238 in soil; 150
pCi/g above background.
The guidelines were derived using conservative assumptions
protective of human health and the environment. The USDOE applied the
surface and subsurface soil criteria when evaluating the effectiveness
of the removal actions. The USDOE implemented the guidelines on the
basis of compatibility with the criteria used for the same purpose by
the EPA. No further removal was conducted when sampling data
demonstrated that the residual contamination guidelines for soil were
met for that property.
The USDOE revised the guidelines in the early 1990's by the
application of the As Low As Reasonably Achievable (ALARA) principle.
In applying the principle of reducing exposure to levels ALARA, the
USDOE established cleanup goals for properties of 5 pCi/g, regardless
of depth of contamination. These guidelines applied to Th-232 and Ra-
226 concentrations; however, they were not applicable to naturally
occurring background radioactivity in soils near the Site.
In 1997, when disposal facilities which were licensed or permitted
to accept radiological wastes came online, the approximately 38,500-
cubic yard interim storage pile was removed by the USDOE and shipped
off-site for disposal.
Approximately 41,500 cubic yards of buried contaminated materials
within the footprint of the former interim storage pile were removed
and shipped off-site for disposal by the USACE under a separate CERCLA
removal action that began in 1998. This action is documented in the
Engineering Evaluation/Cost Analysis for the Removal of Subsurface
Materials at the Wayne Site (1998).
Remedial Investigation and Feasibility Study
The Site was addressed through a Remedial Investigation/Feasibility
Study (RI/FS) process which evaluated the conditions at the Site, the
need for remedial action, and the possible cleanup alternatives. In
late 1989, the USDOE began an intensive study of the remaining
contamination at and around the Site. The field work was completed in
December 1991. Historical data and the results documented in the RI
Report (1993) delineated the nature and extent for contamination. The
Baseline Risk Assessment (BRA) evaluated potential health and
ecological risks if no remedial action was taken at the Site. The BRA
determined that remedial action was warranted because of the potential
for cancer risks above the upper risk threshold of 10-4
identified by EPA as protective to occur if existing institutional
controls are not maintained in the future. The main exposure pathway of
concern was direct contact with radiologically contaminated soils
remaining at the Site.
The FS Report (1999) evaluated the alternatives for remedial action
at the Site. The evaluation of a range of remedial actions for the Site
was based upon the risk assessment presented in the FS. The overall
strategy was to address the radioactively contaminated wastes which had
been disposed at the Site. The FS evaluated technologies that were
appropriate for the media of concern, developed and screened
alternatives capable of addressing the contaminated media, and
evaluated in detail a subset of the developed alternatives using
evaluation criteria specified under CERCLA.
Selected Remedy
In May 2000, the EPA and the USACE issued a Record of Decision
(ROD) identifying the selected remedy to address the remaining
radioactive wastes, chemical waste, operations building demolition, and
groundwater at the Site. The Remedial Action Objectives specified in
the ROD were:
To eliminate or minimize the potential for humans to
ingest, come into dermal contact with, or inhale particulates of
radioactive constituents, or to be exposed to external gamma radiation
to achieve the level of protection required by the NCP (10-4
to 10-6 risk range) and meet the substantive requirements of
10 CFR part 20, subpart E.
To reduce chemical COC levels in impacted media to levels
that would be protective based on site-specific risk and groundwater
impact evaluations.
To return impacted groundwater to conditions consistent
with groundwater applicable or relevant and appropriate requirements
(ARARs).
To protect the integrity of the clay layer in order to
ensure protection of the lower groundwater aquifer.
To reduce potential exposure to radium and thorium in soil
to levels that would be protective for the intended land use as
established by site-specific risk analysis.
To reduce exposure to uranium to levels that would be
protective for the intended land use.
To eliminate or minimize toxicity, mobility, and/or volume
of impacted soils.
To eliminate or minimize the potential migration of
contaminants into stream and storm drain sediments by surface water
runoff, or by infiltration or percolation that would result in
contamination of the groundwater.
To comply with chemical and action-specific ARARs.
To prevent exposures from radioactivity in buildings and
structures greater than the guideline limits.
To access and address the contaminated soils beneath the
building.
To eliminate or minimize potential exposure to external
gamma radiation.
To eliminate or minimize toxicity or mobility, and/or
volume of contaminants.
The major components of the selected remedy and remedial actions
performed at the Site are summarized below:
Excavation and disposal of the remaining contaminated
subsurface
[[Page 50047]]
materials to an average concentration of 5 pCi/g of Ra-226 and Th-232
combined, above naturally occurring background concentrations at the
Site, and an average concentration of 100 pCi/g of total uranium above
naturally occurring background, as determined by surveys consistent
with the Multi-Agency Radiation Survey and Site Investigation Manual
(MARSSIM) (2000).
Excavation and disposal of chemically contaminated soils
above levels calculated to be protective of groundwater or above levels
protective for unrestricted uses of the property (with regard to
chemicals of concern) as specified in the ROD.
Decontamination and demolition of the site operations
building on the Site, removal and off-site disposal of demolition
debris, and removal and off-site disposal of contaminated materials
under this building.
Removal and treatment of groundwater encountered during
excavation to meet the pretreatment discharge standards of the
receiving Publicly Owned Treatment Works prior to release.
Implementation of a five-year groundwater monitoring
program to establish groundwater quality after contaminated soil has
been removed.
Maintenance of the integrity of the subsurface clay layer
that acts as a hydraulic barrier protecting the lower aquifer at the
Site.
Site restoration activities that will allow for beneficial
unrestricted use in the future.
Remedial Actions
Wayne Interim Storage Site (The Site)
Under the May 2000 ROD, an additional 55,410 cubic yards of
contaminated material and building debris were excavated and disposed
of at an off-site licensed disposal facility. The elements of the
remedial construction activities and construction quality assurance and
quality control (QC) are detailed in the Post Remedial Action Report
Wayne Interim Storage Site (PRAR) (2004). The USACE managed and
supervised all construction activities to ensure compliance with the
remedial design, work plans, and construction specifications. The EPA
provided oversight of the cleanup actions.
Vicinity Properties
Following the remedial actions at the Site, the USACE reviewed the
cleanup actions previously taken by the USDOE at the VPs. The review
consisted of comparing the USDOE radiological screening and sampling
data from the VPs and the unrestricted use criteria applied by the
USDOE to the cleanup values established in the ROD, and as appropriate,
the State of New Jersey Administrative Code.
A Technical Memorandum documented the evaluation of the VPs and
specifically identified and listed each property previously remediated
by the USDOE. On the basis of this paper review, the USACE conducted
additional subsurface soil sampling at four VPs in May and June 2003.
Following the review and sampling, the USACE determined that prior
USDOE actions were sufficient to meet the ROD cleanup criteria at all
VPs, with the exception of the Wayne Township (Sheffield) Park and a
small right-of-way (ROW) area adjacent to the Pompton Plains Cross
Road.
The USACE conducted additional excavation and off-site disposal of
contaminated residual soils in July and August 2003 at the Wayne
Township (Sheffield) Park and the road ROW property consistent with the
cleanup levels documented in the ROD. These actions were documented in
an Explanation of Significant Differences (ESD) (2003). Final Status
Surveys performed in compliance with MARSSIM demonstrated that ROD
cleanup levels were achieved for radiological and chemical constituents
of concern. Approximately 2,300 cubic yards of additional soil were
excavated from these two VPs.
The elements of the remedial construction activities including
construction QC requirements, the USACE inspections, post-excavation
final status surveys, and final as-built drawings, are described in the
Post Remedial Action Report Wayne Interim Storage Site Vicinity
Properties Wayne Township (Sheffield) Park (2008) and Post Remedial
Action Report Wayne Interim Storage Site Vicinity Properties Pompton
Plains Crossroad Right-of-Way Property (2008). The USACE managed and
supervised all construction activities at the VPs to ensure compliance
with the remedial action work plans and construction specifications.
The EPA provided oversight of the cleanup actions.
Transfer of the real property at 868 Black Oak Ridge Road, Wayne
Township, New Jersey from the U.S. Government to the Township of Wayne
was completed in 2006.
Inaccessible Soils
After the remediation of the Site, documented in the PRAR, it
became necessary to examine the then-current status of a section of
Black Oak Ridge Road and Pompton Plains Cross Road that is adjacent to
the Site. In August 2004, a characterization survey of this roadway was
performed and the results showed areas of subsurface contamination
remained along certain roadway and utility features. These findings
were also documented in the EPA Five-Year Review, indicating that this
area would need to be addressed in the future.
The previously inaccessible soils in this area were made accessible
and addressed in 2009 and 2010. During the 2009 remediation at the
Black Oak Ridge Road, a total of 13 intermodal containers were filled
with 475,000 pounds (237 tons) of contaminated soil and disposed of at
U.S. Ecology in Grandview, Idaho (USEI). During the 2010 remediation,
43 containment sacks containing 447,550 pounds (224 tons) of
contaminated soil, pipe, and debris were disposed of at USEI.
For radiologically-contaminated soil below the Black Oak Ridge Road
roadway, the selected remedy in the ROD, complete excavation and off-
site disposal, was applied. All regions of contamination in previously
inaccessible soils under the Black Oak Ridge Road have been completely
remediated. The analytical data presented in the Construction Close-Out
Report for Roadways and Inaccessible Soils (2011) demonstrate
compliance with the unrestricted use cleanup criteria as set forth in
the ROD.
Groundwater Monitoring
A Long-Term Groundwater Monitoring Program was implemented to
monitor groundwater quality at the Site within the unconfined and
confined aquifers for a period of five years from the conclusion of
remedial activities. Criteria in the ROD were used to evaluate
radioactive and chemical constituent results. A total of 21 wells were
monitored from 2002 until 2006 in accordance with the Wayne Interim
Storage Site Long-Term Groundwater Monitoring Plan Addendum for USACE
In-House Sampling (2003).
Over the course of the five-year monitoring period, a few results
did exceed ROD and other criteria, but did not impact the conclusion
that all groundwater criteria in the ROD had been met. Arsenic was
detected in one well in excess of the ROD criteria, but did not exceed
the EPA maximum contaminant level. This well was in a confined aquifer
located up-gradient of all former disposal areas and was considered
representative of background conditions. Chromium was detected above
the ROD criteria in one monitoring well during the May 2006 sampling
event. The elevated result was
[[Page 50048]]
found in a well that was in a confined aquifer located up-gradient of
all former disposal areas. The well was considered to be representative
of background conditions. The source of the elevated reading was
attributed to chromium leaching into the well water column from the
stainless steel well casing and screen. Previously, an on-site
stainless steel well demonstrated similar elevated chromium results and
was replaced by a polyvinyl chloride (PVC) well. The PVC-cased well
demonstrated true groundwater chromium much less than the ROD criteria.
Following the March 2006 sampling event, the USACE determined that
all monitoring requirements set forth in the ROD had been met. The
Five-Year Review Report completed by EPA in September 2008 stated that
the groundwater monitoring program requirements, as established in the
ROD, had been met. The 21 monitoring wells were abandoned in September
2011 in accordance with New Jersey Department of Environmental
Protection (NJDEP) regulations, specifically Well Construction and
Maintenance; Sealing of Abandoned Wells, N.J.A.C. 7:9D.
Cleanup Goals
The cleanup levels for contaminated soils and groundwater at the
Site and VPs are listed in Table 1, of the Final Close-Out Report for
the W.R. Grace and Co./Wayne Interim Storage Site (2012). Attainment of
these levels will allow for unrestricted use and unlimited exposure of
the properties, as demonstrated in the risk assessment.
Post remedial action sampling was conducted following excavation at
the Site property and VPs including the Wayne Township (Sheffield)
Park, a small ROW area adjacent to the Pompton Plains Cross Road, and a
section of Black Oak Ridge Road. Access was obtained to all properties
and soil was excavated. Post excavation sampling indicated all cleanup
levels for these soils had been met.
After five years of groundwater monitoring, the USACE determined
that all monitoring requirements set forth in the ROD had been met.
This was stated in the 2008 Five-Year Review Report.
Operation and Maintenance
No ongoing monitoring or maintenance is required by the U.S.
Government at the Site. The remediation of previously inaccessible
soils in 2009 and 2010 allowed for the Site to be closed with no land
use controls to monitor.
Five-Year Review
The EPA published a Five-Year Review Report for the Site in
September 2008. The assessment of this five-year review was that the
selected remedy was functioning as intended by the decision documents
and was protective of human health and the environment in the short-
term.
The Issues, Recommendations, and Follow-Up Actions and
Protectiveness Statement of the Five-Year Review Report both state that
``the implemented remedy has left all groundwater and soils suitable
for use without restriction, except for two suspected sub-soil areas
which are currently not accessible.'' The areas in question were
located beneath a roadway to which the USACE could not gain access for
characterization and remediation. The Five-Year Review Report went on
to explain that there were no current risks for either groundwater or
soils and none were expected, as long as access controls for the
inaccessible areas were maintained, resulting in the likely need for a
deed restriction on the areas. However, funds made available through
the American Reinvestment and Recovery Act of 2009 allowed the USACE to
work with Passaic County and remediate the areas consistent with the
selected remedy in the ROD and ESD. This remediation is documented in
the Construction Close-Out Report for Roadways and Inaccessible Soils
(2011).
The remediation of previously inaccessible soils under the roadway
allowed for the Site to be released for unrestricted use with no need
for further Five-Year Reviews.
Community Involvement
Public participation activities for this Site have been satisfied
as required in CERCLA sections 113(k) and 117, 42 U.S.C. 9613(k) and
9617. Throughout the removal and remedial process, EPA and the NJDEP
have kept the public informed of the activities being conducted at the
Site by way of public meetings, progress fact sheets, and the
announcement through local newspaper advertisements on the availability
of documents such as the RI/FS, Risk Assessment, ROD, Proposed Plan and
the Five-Year Review Report.
Determination That the Site Meets the Criteria for Deletion in the NCP
The Site meets all site completion requirements as specified in the
OSWER Directive 9320.2-22, Close-Out Procedures for National Priorities
List Sites. All remedial activities at the Site are complete and the
implemented remedy achieves the degree of cleanup specified in the ROD
and ESD, for all pathways of exposure. Therefore, EPA has determined
that no further response action is necessary at the Site to protect
human health and the environment.
V. Deletion Action
The EPA, with concurrence of the State of New Jersey, through the
Department of Environmental Protection, dated on June 22, 2012, has
determined that all appropriate response actions under CERCLA have been
completed. Therefore, EPA is deleting the Site from the NPL.
Because EPA considers this action to be noncontroversial and
routine, EPA is taking it without prior publication. This action will
be effective on September 30, 2012, unless EPA receives adverse
comments by September 19, 2012. If adverse comments are received within
the 30-day public comment period, EPA will publish a timely withdrawal
