I. Introduction
The Environmental Protection Agency (EPA) Region III announces its
intent to delete the Leetown Pesticides Site, which is located in
Leetown, West Virginia, from the National Priorities List (NPL),
Appendix B to 40 CFR part 300, the National Oil and Hazardous
Substances Pollution Contingency Plan (NCP), and requests comments on
this decision. EPA identifies sites that appear to present a
significant risk to public health or the environment and maintains the
NPL as the list of those sites. As discussed in the NCP at 40 CFR
300.425(e)(3), a site deleted from the NPL remains eligible for
remedial action in the unlikely event that conditions at the site
warrant such action in the future.
EPA will accept comments on the proposal to delete this Site from
the NPL for thirty calendar days after publication of this notice in
the Federal Register.
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 the Leetown Pesticides Site and
explains how the Site meets the deletion criteria.
II. NPL Deletion Criteria
The NCP at 40 CFR 300.425(e) provides that sites may be deleted
from or recategorized on the NPL where no further response is
appropriate. Specifically, this section of the NCP provides that, in
making a determination to delete a site from the NPL, EPA shall
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 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, taking of remedial measures is not appropriate.
The NCP at 40 CFR 300.425(e) further provides that sites may not be
deleted from the NPL until the State in which the site is located has
concurred on the proposed deletion. All sites deleted from the NPL are
eligible for further Fund-financed remedial actions should future
conditions warrant such action. Whenever there is a significant release
from a site deleted from the NPL, the site shall be restored to the NPL
without application of the Hazard Ranking System.
Deletion of a 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.
III. Deletion Procedures
The procedures required to ensure public involvement during a
proposal to delete a site from the NPL are enumerated at 40 CFR
300.425(e)(4). Pursuant to that section, EPA has published this Notice
of Intent to Delete, together with concurrent notices in the local
newspapers in the vicinity of the Site, to announce the initiation of a
30-day public comment period. The public is asked to comment on EPA's
intention to delete the Site from the NPL. All documents supporting
EPA's intention to delete the Site from the NPL are available for
inspection by the public at the information repositories located at the
addresses listed above.
EPA will accept and evaluate public comments on this Notice of
Intent to Delete before making a final decision on the deletion. If EPA
receives any significant comments during the public comment period, the
Agency will prepare a Responsiveness Summary to address those comments.
A deletion occurs when the Regional Administrator places a final
deletion notice in the Federal Register. Once this
[[Page 30208]]
has occurred, each subsequent publication of the NPL will reflect that
the Site has been deleted. Public notices and copies of the
Responsiveness Summary, if any, will be placed in the Site information
repositories listed above.
IV. Basis for Intended Site Deletion
The following site summary provides EPA's rationale for the
proposal to delete the Leetown Pesticides Site from the NPL:
A. Site Background
The Site is located in Leetown, Jefferson County, West Virginia, in
the extreme northeastern portion of the state, approximately 8 miles
south of Martinsburg, West Virginia. The Site consists of three
separate parcels in the vicinity of the town of Leetown which were
contaminated with pesticides: the former Pesticide Pile Area, the
former Pesticide Mixing Shed, and the Crimm Orchard Packing Shed.
The former Pesticide Pile Area is alleged to have received
pesticide-contaminated debris from a fire at a local chemical company
in 1975. The contamination at the former Pesticide Pile Area was the
residue left after the removal of approximately 160 cubic yards of
pesticide-contaminated debris in June of 1983.
The former Pesticide Mixing Shed was used during the active
operation of the Jefferson Orchard to formulate pesticides for use at
the orchard. The eastern portion of the Crimm Orchard Packing Shed was
used for the formulation of pesticides for application at the former
Crimm Orchard and for storing containers of pesticides, most of which
were open and leaking.
The contaminants of concern at the Site included DDT and its
metabolites, DDD and DDE, and the alpha, beta, delta, and gamma isomers
of hexachlorocyclohexane (HCCH). Gamma HCCH is also known as Lindane.
B. History and Characterization of Risk
Evidence of hazardous waste activity was first brought to the
attention of EPA in 1981 by representatives of the National Fisheries
Center in nearby Kearneysville, West Virginia. Between 1980 and 1983,
EPA conducted a number of investigations which included sampling of the
debris pile in the former Pesticide Pile Area and locations in the
immediate vicinity of the Pesticide Pile Area, including residential
wells, the Fisheries Center, the Grey and Bell Springs, and the
Jefferson County solid waste landfill. The Site was proposed for
inclusion on the original Superfund NPL in December of 1982, and
officially placed on the NPL in September of 1983.
EPA conducted sampling for the Remedial Investigation (RI) between
1984 and 1985. The RI focused on areas in the vicinity of Leetown where
the surface disposal of pesticides, agricultural use of pesticides or
the landfilling of pesticides had occurred. The areas to be
investigated were identified through an aerial photographic survey
conducted by EPA and information received from local sources. After
evaluating the results of the RI sampling, EPA narrowed the areas of
concern to the former Pesticide Pile Area, the former Pesticide Mixing
Shed, and the Crimm Orchard Packing Shed. The RI determined the extent
of contamination and the risks to human health and the environment
posed by the contamination in these areas. The RI was followed by a
Feasibility Study (FS), also conducted by EPA, which identified cleanup
alternatives to address those risks.
The RI and FS reports were released to the public for review on
March 6, 1986. This marked the beginning of the public comment period
which closed on March 27, 1986. During the comment period, EPA
recommended Alternative 7 from the FS as EPA's preferred remedial
alternative. A public meeting to discuss EPA's preferred remedial
alternative was held on March 20, 1986. On March 31, 1986, a Record of
Decision (ROD) was issued which identified Alternative 7 as the
Selected Remedy. Alternative 7 consisted of the following actions: (1)
Demolition and off-site disposal of the eastern portion of the Crimm
Orchard Packing Shed and its contents; and (2) anaerobic biodegradation
of the pesticide-contaminated soils from the former Pesticide Pile
Area, the former Pesticide Mixing Shed and the soils from under the
Crimm Orchard Packing Shed. A total estimated volume of 3,600 cubic
yards of soil were to be consolidated and placed in treatment beds to
be constructed on-site.
The demolition and off-site disposal of the eastern portion of the
Crimm Orchard Packing Shed and its contents began on February 24, 1988
and was completed on April 22, 1988. EPA performed treatability studies
for the bioremediation of the consolidated soils on two separate
occasions. The first treatability study, which tested the effectiveness
of anaerobic biodegradation, was performed from May 1986 to April 1987.
This study was not successful in meeting the cleanup levels specified
in the ROD. EPA performed treatability studies for two other biological
treatment processes from April 1989 to January 1990. One process
utilized white rot fungus; the other process utilized a combination of
aerobic and anaerobic biodegradation. Again, neither of these processes
were able to successfully treat the soils to meet the cleanup levels
specified in the ROD.
In 1990, as part of the second phase of treatability studies, EPA
reviewed the cleanup levels established in the ROD to determine if
these levels continued to be appropriate to protect human health and
the environment. During this review, it was discovered that the
methodology used in the 1986 risk assessment was no longer utilized by
EPA in determining risks to human health. Specifically, the 1986 risk
assessment was based on the maximum human exposure to the contaminants
at the Site, including the maximum observed concentrations. However,
the Risk Assessment Guidance for Superfund (RAGS) which EPA issued in
December of 1989, EPA/540/1-89/002, stated that quantitative risk
assessments should be based on Reasonable Maximum Exposure (RME)
scenarios. Because the 1986 risk assessment appeared to be overly
conservative compared to a risk assessment that would result from
utilizing RAGS, EPA recalculated the risks to human health using the
RME scenarios and determined that the contaminants of concern at the
Site did not pose an unacceptable risk to human health or the
environment.
On February 6, 1992, as a result of the revised risk assessment
described above, EPA issued a Proposed Remedial Action Plan (Proposed
Plan) which identified ``No Further Action'' as EPA's preferred
remedial alternative for this Site. Issuance of this Proposed Plan
marked the beginning of the public comment period. On February 20,
1992, a public meeting was held at the National Fisheries Center to
answer questions from community members and facilitate public input on
the Proposed Plan. The public comment period closed on March 6, 1992.
On April 7, 1992, EPA issued a ROD Amendment which identified No
Further Action as the Selected Remedy for the Site.
On April 7, 1992, EPA also issued a Superfund Preliminary Site
Closeout Report. This closeout report indicated that all remedial
action activities required for protection of human health and the
environment had been satisfactorily completed. The ROD Amendment did
not provide any provisions for long-term monitoring of the Site because
the only portion of the originally selected remedial action which was
completed was off-site
[[Page 30209]]
disposal. Therefore, no operation and maintenance activities are
required.
Although the remedial action was completed in April of 1988, the
monitoring wells installed and utilized during the RI had to be
properly abandoned prior to deletion of the Site from the NPL. In the
spring of 1995, the U.S. Army Corps of Engineers, Baltimore District
was tasked under an interagency agreement with EPA to properly abandon
all monitoring wells except those which Jefferson County chose to
retain for use in monitoring the groundwater in the vicinity of its
solid waste landfill. This work was completed in June of 1995. On
August 24, 1995, EPA accepted the Corps of Engineers' report entitled
``Closure Report: Abandonment of Monitoring Wells, Leetown Pesticides
Superfund Site, Leetown West Virginia'' as a final document.
EPA is required to review remedial actions every five years if
hazardous substances, pollutants, or contaminants remain at the site
above levels that allow for unrestricted exposure and unlimited use.
Since neither of these conditions exists at this Site, further five-
year reviews are not warranted and will not be conducted.
C. Conclusion
The NCP at 40 CFR 300.425(e)(ii) provides that EPA may delete a
site from the NPL if ``all appropriate Fund-financed response under
CERCLA has been implemented, and no further action by responsible
parties is appropriate.'' EPA, with the concurrance of the State of
West Virginia, believes that this criterion for deletion has been met.
Therefore, EPA is proposing deletion of this Site from the NPL.
Documents supporting this action are available in the Site information
repositories listed previously in this document.
Dated: June 4, 1996.
