I. Introduction
EPA Region II announces its intent to delete the Marathon Battery
Company site from the NPL and requests public comment on this action.
The NPL is Appendix B to the NCP, which EPA promulgated pursuant to
Section 105 of CERCLA, as amended. EPA identifies sites that appear to
present a significant risk to public health, welfare, or the
environment and maintains the NPL as the list of those sites. Sites on
the NPL may be the subject of remedial actions (RAs) financed by the
Hazardous Substances Superfund Response Trust Fund (the ``Fund'').
Pursuant to Sec. 300.425(e)(3) of the NCP, any site deleted from the
NPL remains eligible for Fund-financed RAs, if conditions at such site
warrant action.
EPA will accept comments concerning the Marathon Battery Company
site for thirty (30) days after publication of this notice in the
Federal Register (until June 7, 1996).
Section II of this notice explains the criteria for deleting sites
from the NPL. Section III discusses the procedures that EPA is using
for this action. Section IV discusses how the Marathon Battery Company
site meets the deletion criteria.
II. NPL Deletion Criteria
The NCP establishes the criteria that the Agency uses to delete
sites from the NPL. In accordance with 40 CFR Section 300.425(e), sites
may be deleted from the NPL where no further response is appropriate.
In making this determination, EPA, in consultation with the State, will
consider whether any of the following criteria have been met:
1. That responsible or other persons have implemented all
appropriate response actions required; or
2. All appropriate Fund-financed responses under CERCLA have been
implemented, and no further cleanup by responsible parties is
appropriate; or
3. The remedial investigation has shown that the release poses no
significant threat to public health or the environment and, therefore,
taking remedial measures is not appropriate.
III. Deletion Procedures
The NCP provides that EPA shall not delete a site from the NPL
until the State in which the release was located has concurred, and the
public has been afforded an opportunity to comment on the proposed
deletion. Deletion of a site from the NPL does not affect responsible
party liability or impede agency efforts to recover costs associated
with response efforts. The NPL is designed primarily for informational
purposes and to assist agency management.
The following procedures were used for the intended deletion of the
Marathon Battery Company site:
1. EPA Region II has recommended deletion and has prepared the
relevant documents.
2. The State of New York has concurred with the deletion decision.
3. Concurrent with this Notice of Intent to Delete, a notice has
been published in local newspapers and has been distributed to
appropriate federal, state and local officials, and other interested
parties. This notice announces a thirty (30)-day public comment period
on the deletion package starting on May 8, 1996 and concluding on June
7, 1996.
4. The Region has made all relevant documents available in the
regional office and the local site information repository.
EPA Region II will accept and evaluate public comments and prepare
a Responsiveness Summary, which will address the comments received,
before a final decision is made. The Agency believes that deletion
procedures should focus on notice and comment at the local level.
Comments from the local community may be most pertinent to deletion
decisions. If, after consideration of these comments, EPA decides to
proceed with deletion, the EPA Regional Administrator will place a
Notice of Deletion in the Federal Register. The NPL will reflect any
deletions in the next update. Public notices and copies of the
Responsiveness Summary will be made available to the public by EPA
Region II.
IV. Basis for Intended Site Deletion
Site History and Background
The Marathon Battery Company site, located in the Village of Cold
Spring, Putnam County, New York, includes a former nickel-cadmium
battery manufacturing facility, the Hudson River in the vicinity of the
Cold Spring pier, and a series of river backwater areas known as East
Foundry Cove, East Foundry Cove Marsh, Constitution Marsh, and West
Foundry Cove. Before the site was remediated, a battery plant and an
underground asphalt- and clay-lined vault containing spoils from
dredging activities in the cove, were located on the facility's
grounds. Twenty-nine houses, located on Constitution Drive, are in the
vicinity of the site.
Nickel-cadmium batteries were manufactured at the plant from 1952-
1979. The plant's wastewater treatment system originally consisted of a
lift station and piping for transfer of all process wastewater into the
Cold Spring sewer system for discharge directly into the Hudson River
at the Cold Spring pier. In addition, a by-pass valve was installed so
that when the lift station was shut down or overloaded, a direct
gravity discharge could be made into the Kemble Avenue storm sewer for
discharge into Foundry Cove.
In the early 1970s, studies conducted by New York University, EPA,
and the New York State Department of Environmental Conservation
(NYSDEC) showed high levels of cadmium contamination in Foundry Cove
sediments. Samples of vegetation and various species of fish, muskrat,
turtle eggs, and green heron revealed high concentrations of cadmium,
as well.
In 1972, the U.S. Department of Justice signed a Consent Agreement
requiring the present and past owners/operators to remove as much
cadmium from the outfall area and channel leading into the cove as was
economically, technically, and ecologically feasible. The dredge spoils
were entombed in the above-described vault. The dredging, however, was
not totally successful. Post-dredging monitoring continued to detect
elevated cadmium concentrations in the cove's sediments, flora, and
fauna. Tidal action slowly flushed some of the remaining cadmium
deposits from the cove into the Hudson River and into Constitution
Marsh, a National Audubon Society sanctuary.
In October 1981, the Marathon Battery Company site was included on
the NPL. In August 1983, EPA and the State of New York signed a
Cooperative Agreement to undertake a remedial investigation and
feasibility study (RI/FS) at the Marathon Battery Company site. The
results of the RI sediment sampling program indicated widespread heavy
metal contamination of the sediments and marsh soils of Foundry
[[Page 21424]]
Cove. The highest level of contamination occurred in East Foundry Cove
Marsh in close proximity to the Kemble Avenue outfall. This area,
characterized by a layer of greenish-white sediment spanning an
approximately 50 by 100 foot area, showed concentrations as high as
171,000, 156,000, and 6,700 milligrams/kilogram (mg/kg) for cadmium,
nickel, and cobalt, respectively. Cadmium levels as high as 2,200 mg/kg
were found in the Hudson River in the vicinity of the Cold Spring pier.
Samples from the former battery facility indicated contamination as
high as 120,000 mg/kg cadmium and 130,000 mg/kg nickel in the rafters,
and up to 600 mg/kg cadmium on the surrounding grounds. Cadmium
concentrations up to 67 mg/kg were found in soils in the adjacent
residential yards.
In March 1986, NYSDEC requested that EPA assume the lead role for
this project. EPA's contractor completed a supplemental RI/FS for the
East Foundry Cove Marsh/Constitution Marsh portion of the site (Area I)
in August 1986.
On September 30, 1986, a Record of Decision (ROD) was signed for
Area I, calling for the dredging of the contaminated sediments
exceeding 100 mg/kg, placement of a clay cap and soil cover on the
excavated marsh areas, restoration of the marsh, chemical fixation of
the excavated sediments, followed by their off-site disposal. Long-term
monitoring was selected for Constitution Marsh.
Supplemental RI activities for the former battery facility (Area
II) were completed in April 1988. A ROD for this operable unit was
signed on September 30, 1988. The selected remedy included
decontamination of the interior of the former battery plant building
and its contents, excavation and chemical fixation of the dredge spoils
vault, excavation and chemical fixation of the cadmium-contaminated
soils on the plant grounds and adjacent properties which exceeded 20
mg/kg (determined by a risk assessment), enhanced volatilization of the
volatile organic compound (VOC)-contaminated soils, and off-site
disposal of the contaminated dust and fixated soils. Long-term
monitoring was selected for the VOC-contaminated ground water
underlying the site. (A search for VOC-contaminated soils on the plant
grounds during the design failed to find a source area. Therefore, the
enhanced volatilization component of the selected remedy was not
designed. The subsequent demolition of the building revealed elevated
levels of VOCs in some sections of the sealed process trenches and an
ejector pit. The contents of the process trench and ejector pit were
sent to an off-site facility for treatment/disposal.)
An RI/FS for the East Foundry Cove, West Foundry Cove, and Hudson
River in the vicinity of the Cold Spring pier portion of the site (Area
III) was completed in June 1989. The Area III ROD was signed on
September 26, 1989. The selected remedy called for dredging one foot of
contaminated sediments to achieve a 95% removal rate from East Foundry
Cove and the Hudson River in the vicinity of the Village of the Cold
Spring pier, followed by chemical fixation and off-site disposal. Long-
term monitoring was selected for West Foundry Cove, a depositional
area.
A consolidated design for Areas I, II (the dredge spoils vault and
the plant grounds), and III was completed in May 1992.
Following the completion of field investigations to more fully
delineate the areas of the adjacent residential properties that
required remediation, in May 1992, this portion of the Area II
remediation effort commenced. When the remedial action was completed in
March 1993, approximately 1,600 cubic yards of contaminated soil had
been excavated and removed.
On March 26, 1989, EPA issued a Unilateral Administrative Order
(UAO) to Marathon Battery Company, Gould Inc., and Merchandise
Dynamics, the property owner, requiring them to decontaminate the
interior of the 114,000-square foot former battery plant (which at the
time was an abandoned book repository) and its contents, to recycle the
decontaminated books, and to properly dispose of contaminated
materials. Following the performance of a pilot-scale study conducted
by Marathon Battery Company's and Gould Inc.'s contractor to evaluate
decontamination techniques, the facility, as well as 4,170 pallets
containing approximately 2.5 million books were decontaminated. Twelve
of seventy-six rolloffs containing debris from the building were
determined to contain hazardous debris and were disposed of at Chemical
Waste Management's hazardous landfill in Model City, New York. The
remaining rolloffs were sent to Waste Management's Modern Landfill in
York, Pennsylvania. While the book and building decontamination work
was completed in December 1991, due to the limited production rate of
available book recycling companies, the recycling of the books
continued until March 1993.
A Consent Decree, in which Gould Inc. agreed to perform the
remedial action and the remaining PRPs, Marathon Battery Company and
the U.S. Army, agreed to a cash settlement, was entered with the
Southern District Court on April 1, 1993. Gould Inc., as the Settling
Work Defendant, chose Sevenson Environmental Services as its
contractor. The U.S. Army Corps of Engineers (USACE) performed
oversight of the work effort.
Full-scale dredging of East Foundry Cove Marsh and East Foundry
Cove and the excavation of the plant grounds began in September 1993.
The treated sediments and soils were stockpiled on the treatment area
for curing and post-treatment testing prior to off-site disposal at
City Management Landfill in Michigan. All treated materials were
subjected to the Toxicity Characteristics Leaching Procedure as
required by EPA and the Extraction Procedure Toxicity Test as required
by the State of Michigan.
Dredging in the Hudson River in the vicinity of the Cold Spring
pier was completed in early July 1994 and dredging of East Foundry Cove
continued until February 1994. All dredged areas underwent post-
remedial sampling and were surveyed to determine whether the proper
concentration or dredging depth was achieved. With regard to East
Foundry Cove Marsh, post-excavation cadmium levels in the sediments did
not exceed the 100 mg/kg action level, averaging 11.75 mg/kg.
In the Hudson River and East Foundry Cove, an average of 10 mg/kg
of cadmium remained, which was consistent with the ROD requirement that
at least one foot of sediment and 95% of the contamination be removed.
The collection of ice and snow on the former battery facility's
roof during the winter of 1993-1994 resulted in the collapse of a
10,000 square foot section of the roof, thereby exposing a portion of
the concrete foundation to the outside elements. This particular
portion of the foundation contained numerous trenches which were used
for waste disposal during the manufacture of nickel-cadmium batteries.
Sample analyses revealed that elevated levels of cadmium and nickel
remained encased in the rubble-filled and cemented-over trenches. Due
to EPA's concern that continued exposure to the elements and freeze/
thaw cycles could cause the concrete floor and/or trenches' cement caps
to heave and crack, possibly resulting in a release of contaminated
dust, the PRPs agreed to demolish the building and remove the
foundation and process trenches. Demolition of the former battery
facility began in
[[Page 21425]]
September 1994 and was completed in January 1995.
Following the demolition of the former battery facility, it was
discovered that a cadmium nitrate tank located on a pedestal
immediately adjacent to the plant had leaked onto the underlying soil
prior to the closing of the plant in 1979. In an attempt to remove this
cadmium-contaminated soil, a twenty-by sixty-foot area was excavated to
a depth of approximately twenty feet (approximately two feet above the
ground-water table). While post-excavation sampling of this area showed
that some cadmium contamination remained in the saturated soils at
levels above the 20 mg/kg action level, and low levels of cadmium were
present in the ground water, it was determined that excavating an
additional four feet of contaminated soil (two feet below the water
table), placing two feet of limestone at the bottom of the excavation
(to keep the cadmium insoluble), and backfilling the excavation with
clean fill would be protective of public health and the environment.
At the completion of the marsh remediation and restoration
activities in April 1995, the marsh was planted with cattails, bull
rush, arrow arrum, and upland shrubs in specified areas.
The plant grounds were regraded and reseeded in July 1995. Fourteen
monitoring wells remain in place on the plant grounds for the long-term
monitoring of the ground water for VOCs and cadmium.
In all, 189,265 tons of treated soils and sediments were
transported off-site (via 1,979 railcars) to City Management Landfill
in Michigan. Chemical Waste Management's hazardous waste landfill in
Model City, New York received 906 tons of hazardous materials.
A Remedial Action Report associated with the remediation of the
adjacent properties was approved on September 28, 1993. A Remedial
Action Report associated with the East Foundry Cove, East Foundry Cove
Marsh, Hudson River in the vicinity of the Cold Spring pier, the former
battery facility, and plant grounds portions of the site was approved
on September 18, 1995. A Superfund Site Close-Out Report was approved
on September 28, 1995.
Summary of Operation and Maintenance and Five-Year Review Requirements
The cattails, bull rush, and arrow arrum, as well as the upland
shrubs, are being monitored on a regular basis by the warden of the
adjacent National Audubon sanctuary, Constitution Marsh.
The Settling Defendants have agreed to monitor the site for up to
thirty years, commencing with the first inspection/monitoring event
that occurred on October 27, 1995.
The long-term monitoring program consists of monitoring the
groundwater, East and West Foundry Cove sediments and surface water and
biological sampling and analysis quarterly the first year, semi-
annually during years two through five, and annually thereafter for a
total of thirty years.
Site inspections are to be coincident with the monitoring events.
The inspections will include visual observations of the marsh soil
cover and erosion controls, groundwater monitoring wells, and general
site conditions. Maintenance, if required, will consist of correcting
observed deficiencies (e.g., repairing ground water monitoring wells)
The fourteen groundwater monitoring wells that comprise the groundwater
monitoring program will be inspected to ensure their integrity. They
will be repaired should they become damaged, or replaced should they
become non-functional.
So that EPA can evaluate the remedy's effectiveness, following each
inspection/sampling event, Gould Inc. is to submit to EPA a monitoring
and inspection program report, summarizing the inspection and sampling
results, and describing any corrective maintenance actions that were
taken. In addition, a review of the long-term monitoring and inspection
program reports will be performed five years after the completion of
the RA to assure that the remedy remains effective in protecting human
health and the environment.
There are no operational requirements related to the implemented
remedy.
Summary of How the Deletion Criteria Has Been Met
Based upon the results of RA sample analyses, survey results, and
site inspections, the site meets the requirements set forth in the
RODs. All contaminated soils and sediments above the specific action
levels set for each operable unit were excavated and/or dredged from
those areas, treated and disposed of off-site. East Foundry Cove Marsh
and the plant grounds have been regraded with clean fill and restored.
An Explanation of Significant Differences, dated May 1995, was issued
by EPA to address the pedestal area on the plant grounds which exceeds
the action level at a depth of 20 feet. However, EPA believes the
placement of two feet of limestone at the bottom of the excavation to
keep the cadmium insoluble, and the backfilling of the excavation with
clean fill is protective of public health and the environment.
EPA and the State have determined that the response actions
undertaken at the Marathon Battery Company site are protective of human
health and the environment.
In accordance with 40 CFR Sec. 300.425 (e), sites may be deleted
from the NPL where no further response is appropriate. EPA, in
consultation with the State, has determined that all appropriate
responses under CERCLA have been implemented and that no further
cleanup by responsible parties is appropriate. Having met the deletion
criteria, EPA proposes to delete the Marathon Battery Company site from
the NPL.
The State has advised EPA that, upon deletion of the Marathon
Battery Company site from the NPL, it proposes to change the
classification of the site on its Registry of Inactive Hazardous Waste
Sites from a Class 2 (a site where the disposal of a consequential
quantity of hazardous waste has been confirmed and presents a
significant threat to the environment or health) to a Class 4 (a site
that has been properly closed, but requires continued operation,
maintenance, and/or monitoring).
Dated: April 12, 1996.
