I. Introduction
EPA announces its intent to delete the Cedartown Municipal Landfill
Superfund Site (the Site), in Polk County, Georgia from the National
Priorities List (NPL) which constitutes appendix B of the National Oil
and Hazardous Substances Pollution Contingency Plan (NCP), and requests
comments on this proposed 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 those sites. Sites on
the NPL may be the subject of remedial actions financed by the
Hazardous Substances Superfund Response Trust Fund (Fund). Pursuant to
Sec. 300.425(e)(3) of the NCP, any site deleted from the NPL remains
eligible for Fund-financed Remedial Actions in the event that
conditions at the site warrant such action. EPA will accept comments
concerning this Site for thirty (30) calendar days after publication of
this document in the Federal Register.
Section II of this document explains the criteria for the deletion
of 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
The NCP establishes the criteria that the EPA uses to delete sites
from the NPL. In accordance with 40 CFR 300.425(e), releases may be
deleted from the NPL where no further response is appropriate. In
making this determination, 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; or (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 determined that the release poses no significant
threat to public health or the environment and, therefore, taking of
remedial measures is not appropriate; or (iv) The site is a regulated
treatment, storage, or disposal facility (TSD) regulated under the
authority of the Resource Conservation and Recovery Act (RCRA).
Pursuant to Sec. 300.425(e)(3) of the NCP, any site deleted from
the NPL remains eligible for Fund-financed Remedial Actions in the
event that conditions at the site warrant such action.
III. Deletion Procedures
EPA will accept and evaluate public comments before making a final
decision to delete. Comments from the local community may be the most
pertinent to deletion decisions. The following procedures were used for
the intended deletion of this Site:
(1) EPA Region 4 issued a Record of Decision (ROD) in November
1993. The selected remedy included landfill cover maintenance, controls
to restrict land use and prevent groundwater use, and groundwater
monitoring to ensure that the contaminants were reduced naturally and
did not move away from the site. Groundwater monitoring was to be
continued after groundwater performance standards are achieved. The ROD
contained a contingency for pumping and treating groundwater if the
performance standards could not be attained.
(2) EPA Region 4 issued a ROD amendment in May 1998, following two
and one-half years of groundwater monitoring. Monitoring data indicated
that only manganese remained above the performance standard and did not
appear to be migrating offsite. The amendment changed the remedy to
utilize institutional controls to restrict groundwater use in the areas
beneath the site where performance standards are exceeded and to
eliminate monitoring and the pump and treat contingency.
(3) The Georgia EPD concurred with the proposed deletion decision.
(4) 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 on EPA's Notice of Intent to Delete.
(5) All relevant documents have been made available for public
review in the local Site information repository.
Deletion of a site from the NPL does not itself, create, alter, or
revoke any individual rights or obligations. The NPL is designated
primarily for information purposes and to assist EPA management. As
mentioned in section II of this document, 40 CFR 300.425(e)(3) states
that deletion of a site from the NPL does not preclude eligibility for
future Fund-financed response actions.
Any comments received during the notice and comment period will be
evaluated before the final decision to delete. EPA will prepare a
Responsiveness Summary, if necessary, which will address any comments
received during the public comment period.
A deletion occurs after the EPA Region 4 Regional Administrator
places a document in the Federal Register. The NPL will reflect any
deletions in the next final update. Public notices and copies of the
Responsiveness Summary will be made available to local residents by EPA
Region 4.
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 Cedartown Municipal Landfill site is located in Polk County on
the outskirts of the City of Cedartown, Georgia, approximately 62 miles
northwest of Atlanta, Georgia. The Site is situated on the western edge
of Cedartown and is bordered on the east by Tenth Street, the south by
Route 100 (Prior Station Road), and the north and west by undeveloped
and/or agricultural land. Property to the east of the Site consists of
an industrial complex. Land to the north, west and south of the Site is
a mixture of residential, agricultural, and
[[Page 64670]]
undeveloped land. The Site lies within the limits of the City of
Cedartown.
The Site occupies approximately 94 acres and has wooded areas along
the north, south and west. A seasonal stream and pond, which appear
during periods of high precipitation, exist approximately 700 feet west
of the Site perimeter. The eastern half of the Site is covered by thick
grasses. Approximately 10 acres of land, situated between the eastern
and western halves of the Site, were not used for landfill operations.
One leachate seep was observed on-site.
B. History
The Site encompasses a former iron ore mine which subsequently was
used as a municipal landfill. While the landfill received primarily
municipal solid sanitary waste during its operation, quantities of
industrial waste were also reportedly disposed at the Site. The
industrial wastes disposed at the Site may have included the following:
Sludge from an industrial waste water treatment system,
Animal fat and vegetable oil skimmings from a separation
unit,
Liquid dye wastes,
Latex paint and paint sludges, and
Plant trash.
In 1979, in accordance with then applicable State regulations
pertaining to the closure of landfills, the landfill was covered with a
layer of clay soil varying in thickness from one to 12 feet. A
vegetative cover was then planted over the soil layer to prevent
erosion.
From 1985 to 1987, EPA evaluated conditions at the Site and
identified areas of potential investigation. EPA then proposed the Site
for inclusion on the National Priorities List (NPL) in June 1988 and
finalized the listing in March 1989. In November 1993, EPA issued a
Record of Decision (ROD) for the Site. The ROD selected a remedy
consisting of the following:
Cover maintenance and seep controls,
Institutional controls to minimize land use and prevent
groundwater use,
Surface water monitoring to assess whether contaminants
were leaching from the seep,
Groundwater monitoring to assess the migration and/or
natural attenuation of contaminants,
Implementation of a contingency pump and treat system if
groundwater performance standards were not met, and
Continued groundwater monitoring after groundwater
performance standards were achieved.
EPA Region 4 issued a ROD amendment in May 1998 which amended the
remedy to utilize institutional controls to restrict groundwater use in
the areas beneath the site where performance standards are exceeded and
to eliminate monitoring and the pump and treat contingency. The City of
Cedartown (the City) has implemented the required institutional
controls to restrict groundwater use at the Site. The City has annexed
all property which lies above the landfill area. A city ordinance is in
place to restrict the installation of wells on these properties.
Additional ordinances restrict the placement of groundwater wells on
adjacent property.
C. Characterization of Risk
Groundwater monitoring for two and one-half years has demonstrated
that levels of all constituents of concern, except manganese, are below
performance standards. Groundwater concentrations of manganese have
remained stable in the wells which exceed the standard. Elevated levels
of manganese have not been detected in more distant wells. In addition,
EPA analysis of groundwater data demonstrates that elevated manganese
may be caused by mining activities which occurred before the Site was
used as a municipal landfill. Risk to human health has been reduced to
acceptable levels by controlling access to contaminated groundwater.
Institutional controls implemented by the City will restrict the use of
groundwater in areas where performance standards are not met. The
results of the ecological risk assessment indicated that the Site
provides a habitat for a variety of wildlife, but that chemical
exposures on the Site do not represent a threat to wildlife which may
inhabit the area. No endangered or sensitive resident species or
critical habitats were identified in the study area.
EPA believes that conditions at the Site pose no unacceptable risks
to human health or the environment. One of the three criteria for
deletion specifies that EPA may delete a site from the NPL if ``the
responsible parties or other parties have implemented all appropriate
response actions required.'' EPA, with concurrence from the Georgia
Environmental Protection Division (EPD), believes that this criterion
for deletion has been met. Subsequently, EPA is proposing deletion of
this Site from the NPL. Documents supporting this action are available
from the regional public docket. Since waste will remain on the site, a
five year review will be required in the future.
EPA, with concurrence of the Georgia EPD, has determined that all
appropriate response under the CERCLA have been completed, and that no
further action by responsible parties is necessary. Therefore, EPA
proposes to delete the Site from the NPL and requests public comments
on the proposed deletion.
Dated: September 30, 1998.

Acting Regional Administrator, Region 4.
