I. Introduction
The Environmental Protection Agency Region II announces its intent
to delete the Denzer & Schafer X-Ray Company Site, located at 186
Hickory Lane (Block 858, Lot 46A), in Bayville, Berkeley Township,
Ocean County, New Jersey, from the National Priorities List (NPL) and
requests public comment on this action. The NPL constitutes appendix B
of the NCP, 40 CFR part 300. 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. As
described in Sec. 300.425(e)(3) of the NCP, any site deleted from the
NPL remains eligible for Fund-financed remedial actions if conditions
at the site warrant such action.
EPA will accept comments concerning the Denzer & Schafer X-Ray
Company Site for thirty days after publication of this document in the
Federal Register.
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 how the Site meets the deletion
criteria.
II. NPL Deletion Criteria
Section 300.425(e)(l)(i)-(iii) of the NCP provides that sites may
be deleted from the NPL where no further response is appropriate. In
making this determination, EPA will consider whether any of the
following criteria have been met:
(i) EPA, in consultation with the State, has determined that
responsible or other parties have implemented all appropriate response
actions required; or
(ii) All appropriate Fund-financed responses under CERCLA have been
implemented and EPA, in consultation with the State, has determined
that no further cleanup by responsible parties is appropriate; or
(iii) Based on a remedial investigation, EPA, in consultation with
the State, has determined that the release poses no significant threat
to public health or the environment and, therefore, taking of remedial
measures is not appropriate.
III. Deletion Procedures
The following procedures were used for the intended deletion of
this site:
(1) EPA Region II and the State of New Jersey issued a Record of
Decision (ROD) which documented that no further remedial action is
necessary at the Denzer & Schafer Site to ensure protection of human
health and the environment;
(2) The State of New Jersey concurred with the proposed deletion
decision;
(3) A notice has been published in the local newspaper and has been
distributed to appropriate federal, state and local officials and other
interested parties announcing the commencement of a 30 day public
comment period for EPA's Notice of Intent to Delete; and
(4) All relevant documents have been made available for public
review in the local Site information repositories.
Deletion of the Site from the NPL does not itself create, alter, or
revoke any individual's rights or obligations. The NPL is designed
primarily for informational purposes and to assist Agency management.
As mentioned in Section II of this document, Sec. 300.425(e)(3) of the
NCP states that deletion of a site from the NPL does not preclude
eligibility for future response actions.
For deletion of this Site, EPA's Region II office will accept and
evaluate public comments on EPA's Notice of Intent to Delete before
making a final decision to delete. If necessary, the Agency will
prepare a Responsiveness Summary, which will address any significant
public comments received during the public comment period.
The deletion occurs when the EPA Regional Administrator places a
final notice in the Federal Register. Generally, the NPL will reflect
any deletions in the final update following the Notice. Public notices
and copies of the Responsiveness Summary will be made available to
local residents by the Region II Office.
IV. Basis for Intended Site Deletion
The following site summary provides the Agency's rationale for the
proposal to delete this Site from the NPL.
A. Site Background
The Denzer & Schafer X-Ray Company was located at 186 Hickory Lane
(Block 858, Lot 46A) approximately 4,700 feet west of Route 9 in the
Bayville area of Berkeley Township. Barnegat Bay is approximately two
miles to the east of the Site and Tom's River is two miles to the
north.
B. History
The Denzer and Schafer X-Ray Company was engaged in the reclamation
of silver from microfilm and x-rays. Past activities at the facility
have included the reclamation of silver by chemical stripping or
incineration of spent film. In 1974, the company switched from
incineration to a caustic soda and salt silver reclamation process.
Between 1974 and 1981, the facility disposed of its stripping solution
by discharging it to the plant's subsurface sanitary septic system.
In addition to the silver recovery business, Microindustries, Inc.,
a microfilming service company, was located at the Site.
Microindustries, Inc. was in operation since 1970 and operated
exclusively as a microfilming service company. Microfilm processing
wastes, such as photographic developers and fixers, were generated as
part of the company's operations. These wastes were discharged to the
plant's sanitary septic system prior to 1981.
Periodic sampling of wells installed by the owner since August 1981
and analyses of soil samples collected at the Site indicated that waste
from past operations contaminated ground water and soils at the Site.
The Site was proposed for inclusion on the NPL on December 30, 1982
and subsequently added to the NPL on September 8, 1983.
In 1986, DEP under a cooperative agreement with EPA, began a
Remedial Investigation and Feasibility Study (RI/FS). Based on the
results of the multi-phased RI and subsequent studies, a Record Of
Decision (ROD) was signed by the Regional Administrator on September
28, 1995. The ROD documented the decision that no further remedial
action was necessary at the Denzer & Schafer X-Ray Site because the
conditions pose no unacceptable risk to human health and the
environment. The State of New Jersey will continue to monitor the
groundwater because some
[[Page 44220]]
residual lead contamination remains in the aquifer above drinking water
standards near the old source area.
In April 1996, EPA conducted a removal assessment on the abandoned
facility and subsequently remediated chemicals left at the site. In
September 1996, the remaining underground storage tank was excavated
and removed.
In June 1997, the Berkeley Development Corporation hired
Brinkerhoff Environmental Services to sample, demolish and dispose of
the remaining plant building and debris and properly abandon the two
remaining septic systems. This work was completed in August 1997.
C. Characterization of Human Health Risk
The RI included the collection and analysis of soil, ground water
and air samples, an aquifer testing program which included a pump test,
borehole gamma ray logging, a surface electromagnetic conductivity
survey, tank testing, test pit excavation and sampling, and process
waste water sampling.
Groundwater
Hazardous substances were found in the ground water above Maximum
Contaminant Levels (MCLs).
The RI and supplemental investigations concluded that lead in the
ground water is the only contaminant that exceeds Federal and State
Drinking Water Standards. Currently, there is not a verified toxicity
factor for lead that can be used in normal risk assessment
methodologies to determine the health risks associated with this
contaminant. However, EPA has developed the Integrated Exposure Uptake
Bio-Kinetic Model (IEUBK) as a useful tool to aid in making more
informed decisions about the concentrations of lead in the environment
that might be expected to impact human health.
The IEUBK Model was designed to model exposure from lead in the
environment to predict blood levels in children. Incorporating site-
specific soil and ground water data into the model predicted that 100
percent of the population would be below the threshold of 10 micrograms
per deciliter (ug/dl) for children exposed to lead off site. For
children exposed to lead on site, 99.99 percent of the population would
be below the threshold of 10 ug/dl. These results indicate that for
both future residential land use on and off site, the levels are
consistent with Superfund's lead directive that employs a level of
protectiveness which results in 95% of the population distribution
falling below 10 ug/dl.
However, since the aquifer still exhibits low levels of
contamination at the Site itself, DEP and EPA developed a monitoring
program which included sampling of ground and surface waters and
sediment, including the intermittent pond directly east of the Denzer &
Schafer X-Ray Company building, Potter Creek to the south and Mill
Creek to the north.
In February 1996, the sampling showed lead levels (123 ppb and 19.8
ppb) above drinking water standards (15 ppb) in two of the five
groundwater monitoring wells and elevated lead levels (1.9 ppb) in the
headwaters of Mill Creek, approximately 5,000 feet to the northwest of
the source area, and in Potter Creek (lead--3.2 ppb), approximately
2,000 feet to the southeast of the source area. The lead was found at
levels below the Federal Water Quality Criteria and therefore, does not
represent a risk to human health or the environment. Upon further
consultation with DEP and EPA's Biological Technical Assistance Group
(BTAG), EPA concluded that, because of the great distances separating
them, the lead found in the groundwater adjacent to the source area is
not related to the lead found in the headwaters of the two creeks, and
no future sampling of the creeks would be necessary.
DEP established a Classification Exception Area in January 1998
based on the ground water monitoring to ensure that new wells will not
be installed in the area without appropriate precautions.
Air and Surface Water
Air samples collected during both phases of the RI showed levels of
contamination similar to normal background levels.
Surface water samples were generally free of priority pollutant
compounds.
Soils
Some subsurface soils on-site exceed the health-based standards for
silver. However, it was determined that soil contamination does not
pose an unacceptable risk. The possibility for oral, dermal, and
inhalation exposure to silver in subsurface soils is remote.
D. Ecological Risk
Ecological risks were not characterized because the significant
risk is associated with contaminated ground water and no exposure
pathway exists.
E. Protectiveness
One of the three criteria for deletion specifies that EPA may
delete a site from the NPL if the remedial investigation has shown that
the release poses no significant threat to public health or the
environment and, therefore, taking of remedial measures is not
appropriate. EPA, with the concurrence of the DEP, believes this
criterion for deletion has been met. Details on the decision can be
found in the ROD issued in September 1995. Subsequently, EPA is
proposing deletion of this Site from the NPL. Documents supporting this
action are available from the docket.
