ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 300
[FRL-5428-2]
National Oil and Hazardous Substance Pollution Contingency Plan;
National Priorities List
AGENCY: Environmental Protection Agency.
ACTION: Notice of intent to delete the Gallaway Pits Superfund Site,
Fayette County, Tennessee from the National Priorities List (NPL).
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) Region 4 announces
its intent to delete the Gallaway Pits Site from the National
Priorities List (NPL) and requests public comment on this proposed
action. The NPL constitutes Appendix B of 40 CFR part 300 which is the
National Oil and Hazardous Substances Pollution Contingency Plan (NCP),
which EPA promulgated pursuant to Section 105 of the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA) of
1980, as amended. EPA and the State of Tennessee Department of the
Environment and Conservation (TDEC) have determined that the Site poses
no significant threat to public health or the environment and,
therefore, further remedial measures pursuant to CERCLA are not
appropriate.

SUPPLEMENTARY INFORMATION:
Introduction
The Environmental Protection Agency (EPA) Region 4 announces its
intent to delete the Gallaway Pits Site from the National Priorities
List (NPL), Appendix B of National Oil and Hazardous Substances
Pollution Contingency Plan (NCP), 40 CFR Part 300, and requests
comments on this deletion. 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 these sites. As described in Section
300.425(e)(3) of the NCP, sites deleted from the NPL remain eligible
for remedial actions in the unlikely event that conditions at the site
warrant such action.
EPA will accept comments on the proposal to delete this Site for
thirty days after publication of this notice in the Federal Register.
NPL Deletion Criteria
Section 300.425(e) of the NCP provides that releases may be deleted
from, or recategorized on the NPL where no further response is
appropriate. EPA, in consultation with the State of Tennessee, has
concluded that the Gallaway Pits Site meets the following criteria for
site deletion:
(i) All appropriate fund-financed response actions have been
implemented; and
(ii) All appropriate response under CERCLA has been implemented.
Even if a site is deleted from the NPL, where hazardous substances
remain at the site above levels that allow for unlimited use and
unrestricted exposure, EPA's policy is that a subsequent review of the
site will be conducted at least every five years after the initiation
of the remedial action at the site. If new information becomes
available which indicates a need for further action, EPA may initiate
remedial actions. Whenever there is significant release from a site
deleted from the NPL, the site may be restored to the NPL without the
application of the Hazardous Ranking System.
Deletion Procedures
The following procedures were used for the intended deletion of
this Site: (1) EPA Region 4 issued a Final Close Out Report which
addressed the Site conditions, quality assurance and control during
construction, and technical criteria for satisfying the completion
requirements; (2) a notice has been published in the local newspaper
and has been distributed to appropriate federal, state, and local
officials announcing the commencement of a 30-day public comment period
on EPA's Notice of Intent to Delete; (3) All relevant documents have
been made available for public review in the local Site information
repositories; and TDEC has concurred with the proposed deletion
decision.
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 information purposes and to assist Agency management. As
mentioned in Section VI of this Notice, Section 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 Regional Office will accept and
evaluate public comments of EPA's Notice of Intent to Delete before
making a final decision to delete. If necessary, the Agency will
prepare a Responsiveness Summary to address any significant public
comments received.
A deletion occurs when the Regional Administrator places a final
notice in the Federal Register. Generally, the NPL will reflect
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 Regional office.
Basis for Intended Site Deletion
The following site summary is the Agency's rationale for the
proposal to delete Gallaway Pits Site from the NPL.
A. Site Background and History
The Gallaway Pits Site (five-acres) was extensively mined for sand
and gravel, producing a landscape dotted with water-filled pits up to
50 feet deep. Sampling of the pond water and sediments showed elevated
levels of pesticides. The groundwater samples did not reveal any
contamination; however, potential existed for groundwater contamination
because of the types and quantities of waste at the site.
In October 1983, the EPA conducted an emergency cleanup. The
cleanup consisted of the excavation and off-site disposal of
contaminated sludge and the on-site treatment of the pond water. The
treatment process involved the carbon filtration of the pond water to
limits established by the Tennessee Department of Health and
Environment (TDHE), Division of Water Quality Control.
The Remedial Investigation Report included a sampling program for
each of the potentially affected environmental media: surface water,
sediment, surface soils, and groundwater. A quantitative risk
assessment was performed for various contaminant exposure pathways.
Based on the available data and risk assessment assumptions, the
exposure pathways presented no unacceptable risks to human receptors.
The only unacceptable risk presented by the Site was the potential risk
to off-site ecology.
The Record of Decision (ROD) outlined the following selected
remedial actions: (1) Dilution of water in ponds 1, 2, and 5 with city
water to meet ambient water quality criteria and subsequent discharge
to an unnamed tributary of Cane Creek; (2) excavation of contaminated
sediments from ponds 2 and 5, and consolidation of these sediments in
pond 1; (3) institutional controls, such as fencing around pond 1,
restrictions on mining, and methods to ensure that future land uses are
compatible with the selected remedy; (4) proper site closure under
Subtitle C of RCRA, including capping of pond 1; and (5) operation and
maintenance (O&M) activities that include groundwater monitoring and
inspection and maintenance of the cap.
B. Remedial Planning Activities
A Remedial Design was performed in the field for the selected
actions recommended by the ROD at the Site. Listed below are the design
criteria: (1) Determine a kiln dust/sediment ratio for the
solidification process; (2) determine the below grade excavation
configuration to store the solidified waste; (3) design a RCRA cap over
the below grade configuration; (4) determine the safety factor against
bearing capacity failure of foundation soils underlying the solidified
waste and RCRA cap; (5) perform an effective analysis of foundation
soils to check for possible detrimental settlement of RCRA cap; and (6)
design a drainage ditch system to collect and route runoff away from
the RCRA cap.
[[Page 6809]]
C. Remedial Construction Activities
Construction activities were initiated in June 1987 at the site.
The construction activities included: (1) Pond water sampling; (2)
water evacuation of ponds; (3) solidification and excavation of pond
sediments; (4) construction of the RCRA cap; (5) site closure and (6)
monitoring well installation.
All of the completion requirements for this site have been met as
required by OSWER Directive 9320.2-3C. Confirmatory ground water
sampling at the site provides further assurance that the site continues
to pose no threat to human health or the environment. The only
remaining activity to be performed at the site is minor O&M that is
guaranteed by the State of Tennessee.
D. Community Relations Activities
Residents near the Site are aware of activities that have taken
place at Gallaway Pits. A public meeting was held on July 21, 1986, to
present a summary of the RI/FS process and to explain the proposed
remedies for the cleanup of the site. Fact sheets were prepared and
distributed to the mailing list. Comments received during the public
comment period were addressed in the responsiveness summary of the ROD.
Because Gallaway Pits is a companion to the Arlington Blending Site,
the residents of the community are kept informed through community
relations efforts held concerning the Arlington Blending Site.
E. Summary of Operation and Maintenance
The State of Tennessee will implement the O&M plan that will ensure
that the cap remains protective of public health, welfare and the
environment. O&M activities will consist of scheduled inspections and
periodic maintenance of the exclusion zone and periodic sampling of
monitoring wells.
F. How Gallaway Pits Meets NPL Deletion Criteria
Section 300.425(e) of the NCP provides that releases may be deleted
from, or recategorized on the NPL where no further response is
appropriate. EPA, in consultation with the State of Tennessee, has
concluded that the Gallaway Pits Site meets the following criteria for
site deletion:
(i) All appropriate fund-financed response actions have been
implemented; and
(ii) All appropriate response under CERCLA has been implemented.
G. State Concurrence to Delete Gallaway Pits Site
Refer to Attachment I.
EPA, in consultation with the State of Tennessee, has concluded
that the Gallaway Pits Site meets the following criteria for site
deletion: (1) EPA and the State of Tennessee have implemented all
appropriate response actions required; (2) All appropriate response
under CERCLA has been implemented; and (3) the confirmation sampling
done after the cap was completed shows that the Gallaway Site poses no
significant threat to public health or the environment and, therefore,
taking of further remedial measures is not appropriate. EPA and the
State of Tennessee believe that the above listed criterions for
deletion have been met. Subsequently, EPA is proposing deletion of the
Gallaway Pits Site from the NPL. Documents supporting this action are
available from the docket.
