ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 300
[FRL-7844-6]
National Oil and Hazardous Substances Pollution Contingency Plan;
National Priorities List
AGENCY: Environmental Protection Agency.
ACTION: Direct final deletion of the York County Solid Waste and Refuse
Authority Superfund Site from the National Priorities List.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) Region III is
publishing a direct final notice of deletion of the York County Solid
Waste and Refuse Authority Superfund Site (Site) located in Hopewell
Township, York County, Pennsylvania, from the National Priorities List
(NPL).
The NPL, promulgated pursuant to section 105 of the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA) of
1980, as amended, is appendix B of 40 CFR part 300, which is the
National Oil and Hazardous Substances Pollution Contingency Plan (NCP).
This direct final notice of deletion is being published by EPA with the
concurrence of the Commonwealth of Pennsylvania, through the
Pennsylvania Department of Environmental Protection (PADEP) because EPA
has determined that all appropriate response actions under CERCLA have
been completed and, therefore, further remedial action pursuant to
CERCLA is not appropriate.
DATES: This direct final deletion will be effective February 14, 2005,
unless EPA receives adverse comments by January 13, 2005. If adverse
comments are received, EPA will publish a timely withdrawal of the
direct final deletion in the Federal Register informing the public that
the deletion will not take effect.
ADDRESSES: Comments may be mailed to: Larry Johnson, Community
Involvement Coordinator (3HS43), U.S. EPA Region III, 1650 Arch Street,
Philadelphia, PA 19103 ((215) 814-3239).

V. Deletion Action
I. Introduction
EPA Region III is publishing this direct final deletion of the York
County Solid Waste and Refuse Authority Superfund Site from the NPL.
The 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 described in Sec. 300.425(e)(3) of the NCP, sites
deleted from the NPL remain eligible for remedial actions if conditions
at a deleted site warrant such action.
Because EPA considers this action to be noncontroversial and
routine, EPA is taking it without prior publication of a notice of
intent to delete. This action will be effective February 14, 2005
unless EPA receives adverse comments by January 13, 2005 on this notice
or the parallel notice of intent to delete published in the Proposed
Rules section of today's Federal Register. If adverse comments are
received within the 30-day public comment period on this notice or the
notice of intent to delete, EPA will publish a timely withdrawal of
this direct final deletion before the effective date of the deletion
and the deletion will not take effect. EPA will, as appropriate,
prepare a response to comments and continue with the deletion process
on the basis of the notice of intent to delete and the comments already
received. There will be no additional opportunity to comment.
Section II of this document explains the criteria for deleting
sites from the NPL. Section III discusses procedures
[[Page 74449]]
that EPA is using for this action. Section IV discusses the York County
Solid Waste and Refuse Authority Superfund Site and demonstrates how it
meets the deletion criteria. Section V discusses EPA's action to delete
the Site from the NPL unless adverse comments are received during the
public comment period.
II. NPL Deletion Criteria
Section 300.425(e) of the NCP provides that releases may be deleted
from the NPL where no further response is appropriate. In making a
determination to delete a release 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 (Hazardous Substance Superfund
Response Trust Fund) response under CERCLA has been implemented, and no
further response 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,
the taking of remedial measures is not appropriate.
Even if a site is deleted from the NPL, where hazardous substances,
pollutants, or contaminants remain at the deleted site above levels
that allow for unlimited use and unrestricted exposure, CERCLA Section
121(c), 42 U.S.C. 9621(c), requires that a subsequent review of the
site be conducted at least every five years after the initiation of the
remedial action at the deleted site to ensure that the action remains
protective of public health and the environment. If new information
becomes available which indicates a need for further action, EPA may
initiate remedial actions. Whenever there is a significant release from
a site deleted from the NPL, the deleted site may be restored to the
NPL without application of the hazard ranking system.
III. Deletion Procedures
The following procedures apply to deletion of the Site:
(1) The EPA consulted with the Commonwealth of Pennsylvania on the
deletion of the Site from the NPL prior to developing this direct final
notice of deletion.
(2) The Commonwealth of Pennsylvania concurred with the deletion of
the Site from the NPL.
(3) Concurrently with the publication of this direct final
deletion, a notice of the availability of the parallel notice of intent
to delete published today in the ``Proposed Rules'' section of the
Federal Register is being published in a major local newspaper of
general circulation at or near the Site and is being distributed to the
appropriate federal, state, and local government officials and other
interested parties; the newspaper notice announces the 30-day public
comment period concerning the notice of intent to delete the Site from
the NPL.
(4) The EPA placed copies of documents supporting the deletion in
the Site information repositories identified above.
(5) If adverse comments are received within the 30-day public
comment period on this notice or the companion notice of intent to
delete also published in today's Federal Register, EPA will publish a
timely withdrawal of this direct final notice of deletion before its
effective date and will prepare a response to comments and continue
with the deletion process on the basis of the notice of intent to
delete and the comments already received.
Deletion of a Site from the NPL does not itself create, alter, or
revoke any individual's rights or obligations. Deletion of a site from
the NPL does not in any way alter EPA's right to take enforcement
actions, as appropriate. The NPL is designed primarily for
informational purposes and to assist EPA management. Section
300.425(e)(3) of the NCP states that the deletion of a site from the
NPL does not preclude eligibility for future response actions, should
future conditions warrant such actions.
IV. Basis For Site Deletion
The following information provides EPA's rationale for deleting the
Site from the NPL:
A. Site Location
The York County Solid Waste and Refuse Authority Superfund Site
(Site) is located in Hopewell Township, York County, Pennsylvania,
approximately two miles northwest of the center of Stewartstown
Borough, Pennsylvania. The Site consists of a 135-acre inactive
municipal landfill containing three unlined cells and a plume of
contamination emanating from these cells. Adjacent to the former
landfill is a currently operating, permitted landfill of approximately
45 acres that is not part of the NPL Site.
B. Site History
The York County Solid Waste and Refuse Authority (YCSWRA) was
established in 1971 and commenced landfill operations at the Site by
1974. The landfill operated between 1974 and 1985 and received
approximately 400 tons of waste daily. The landfill ceased operation in
1985 and was closed in accordance with a closure plan approved by the
Pennsylvania Department of Environmental Resources (PADER, now the
Pennsylvania Department of Environmental Protection or PADEP).
An investigation conducted by PADER between 1982 and 1984 revealed
that volatile organic compounds (VOCs) were migrating from the landfill
and contaminating adjacent residential wells. In 1984, YSCWRA entered
into an Agreement for Amicable Action and Consent Decree with PADER
(1984 PADER Agreement) which required YCSWRA to, among other things,
construct a lined landfill, implement a ground water treatment and
monitoring program for the Site, and provide potable water to the
residents whose water was contaminated by the Site. In 1984 and 1985,
YCSWRA installed additional ground water monitoring wells, constructed
and started operating the adjacent lined landfill, and constructed and
started operating the ground water contamination containment/extraction
and treatment system for the Site. The treatment system currently in
operation consists of seventeen pumping wells and three air stripping
treatment towers. Effluent from the air stripping towers is discharged
to two National Pollutant Discharge Elimination System (NPDES)
permitted outfalls on streams adjacent to the former landfill.
Additionally, YCSWRA currently supplies and maintains a point-of-entry
carbon filter treatment system for eight residents and provides bottled
drinking water to two residents whose domestic wells do not appear to
have been impacted by the Site.
EPA completed a Preliminary Assessment/Site Investigation (PA/SI)
for the Site in July 1984. The PA/SI confirmed the earlier findings
that ground water beneath and beyond the landfill was contaminated with
VOCs and that contamination had migrated to adjacent wells. EPA
proposed the Site for inclusion on the National Priorities List (NPL)
in April 1985. The Site was finalized on the NPL on July 22, 1987.
In December 1987, PADER and the YCSWRA entered into a Consent Order
and Agreement requiring YCSWRA to perform a Remedial Investigation and
Feasability Study (RI/FS) at the Site to ascertain the nature and
extent of contamination and evaluate cleanup actions. The RI/FS was
started in 1988 and was finalized in 1994. The Risk Assessment (RA)
completed during the RI/FS identified ground water contamination
beneath and beyond the
[[Page 74450]]
boundaries of the Site as posing an unacceptable level of risk.
On December 29, 1994, EPA issued a Record of Decision (ROD)
selecting remedial action for implementation at the Site. The selected
remedy consisted of the following components:
1. Continued operation of the currently existing ground water
extraction and air stripper treatment system at the landfill;
2. Continued operation and maintenance of the point of entry ground
water carbon filter treatment systems and/or provision of bottled water
for affected private wells as necessary;
3. Continued maintenance of the landfill's soil and vegetated cap
and the passive gas venting system currently in place at the landfill;
4. Continued sampling of ground water and treated water to ensure
that treatment components are effective and ground water remediation is
progressing toward required cleanup levels;
5. Implementation of a monitoring program to assess the
effectiveness of the ground water treatment system and its impact on
down-gradient surface water and wetland habitat;
6. Implementation of a monitoring program to assess the impact of
the treated effluent discharge on the environmental quality of surface
waters and sediments in the streams where the outfalls are located;
7. Deed restrictions to prohibit the installation of new on-Site
wells in areas of contamination that do not meet applicable or relevant
and appropriate requirements (ARARs), which restrictions can be
withdrawn when ARARs are achieved; and
8. Deed restrictions to prohibit the excavation or disturbance of
the soil cap which results in exposing the fill materials.
In 1997, the YCSWRA entered into a Consent Order (1997 Consent
Order) with EPA which required YCSWRA to implement a removal action
consisting of certain actions selected by EPA in the ROD. The 1997
Consent Order did not expressly require that YCSWRA continue
implementation of the pump and treat, maintenance, and sampling
activities called for in the 1984 PADER Agreement; rather, the 1997
Consent Order required that YCSWRA describe to EPA, on a monthly basis,
all actions undertaken at the Site to comply with that 1984 PADER
Agreement. Since 1997, YCSWRA has complied with the 1997 Consent Order
by, among other things, identifying all actions taken at the Site
pursuant to the 1984 PADER Agreement, performed monitoring to assess
the effectiveness of the actions taken pursuant to the 1984 PADER
Agreement on down gradient surface water and wetland habitat and the
impact of the treated effluent discharge on the environmental quality
of surface waters where outfalls are located, implemented deed
restrictions to prohibit the extraction of groundwater from the Site
for drinking water and other residential uses; and implemented deed
restrictions to prohibit all extraction or disturbance of the soil cap
which may result in the exposure of fill material (except for certain
limited exceptions). Deed restrictions were developed and placed in the
deed to the Site by filing the restrictions with the Recorder of Deeds.
The deed restrictions prohibit the use of ground water at the Site and
prohibit unauthorized excavation or disturbance of the soil cap. The
continued need for deed restrictions will be reevaluated during the
Five-Year Reviews which will be conducted for the Site.
On September 27, 2004 EPA issued an Explanation of Significant
Differences (ESD) which announced a significant, but not fundamental,
change to the remedial action selected in the ROD. The ESD eliminated
the items numbered 1-4 in the list above from the components of the
remedial action. EPA made this change because (a) the 1984 PADER
Agreement requires that YCSWRA conduct these actions under PADEP's
oversight, (b) based on YCSWRA's past performance under the 1984 PADEP
Agreement, EPA expects that YCSWRA will continue to conduct these
actions under PADEP's oversight, and (c) YCSWRA is required, under the
1997 Consent Order with EPA, to report to EPA all actions taken to
comply with the 1984 PADEP Agreement on a monthly basis. The ESD
explained that EPA will continue to monitor YCSWRA's performance of
these actions that are required by the 1984 PADEP Agreement through the
monthly reports received pursuant to the 1997 Consent Order.
C. Characterization of Risk
An assessment of the risk associated with the Site was conducted
during the Remedial Investigation to characterize the current and
potential threats to human health and the environment based on
reasonable maximum exposures to contaminants in the ground water, soil,
migration of contaminants to surface water, sediments, and exposure to
the air. The Risk Assessment (RA) identified ground water contamination
beneath and beyond the boundaries of the Site as posing an unacceptable
level of risk. The RA was used to evaluate the need for remedial action
and to determine the levels to which site related contaminants would
need to be treated to ensure the protection of human health and the
environment. Current land use in the vicinity of the Site is
residential and agricultural and is expected to remain as such in the
future. Ground water beneath the Site is classified as a source of
drinking water and contaminants from the Site have migrated towards
private drinking water wells through the ground water flow system.
Residents who obtain water from private wells which have an in-place
point of entry (POE) carbon filter treatment systems filter treatment
system. The supply, maintenance and proper disposal of the filters is
conduced by YCSWRA and is required by the 1984 PADER Agreement.
Currently there is a 3\1/2\-13 foot vegetated soil cover over the
former landfill. As a result no risk to human health or the environment
is currently present nor should any future risk occur as long as the
cap integrity is maintained.
D. Future Activity
Operation and Maintenance
The YCSWRA maintains a permanent office at the landfill and
performs regularly scheduled monitoring and response activities which
include monitoring NPDES discharges, flow rates from remediation wells,
depth-to-water in remediation wells, water quality in remediation and
monitoring wells, water quality in residential wells, and groundwater
flow; maintaining residential filters; and maintaining the cap and
vegetative cover. Pumping and treating, which is being completed under
the 1984 PADER Agreement, has been successful in containing
contaminated ground water and in providing a potable water supply to
residents with impacted wells. Pumping and treating will be continued
until the maximum contaminant levels (MCLs) for each contaminant of
concern or background, which ever is more stringent, is achieved and
maintained throughout the entire plume of contamination for a period of
12 consecutive quarters. Residential filtration units will continue to
be maintained for those residences whose wells are affected.
Five-Year Reviews
The NCP requires that if EPA selects remedial action that results
in any hazardous substances remaining at a site above levels that allow
for unlimited use and unrestricted exposure, EPA must conduct a review
of such remedial
[[Page 74451]]
action no less often than every five years following initiation of that
remedial action to ensure that human health and the environment are
being protected. EPA has determined as a matter of policy that such
reviews will also be conducted if a removal action leaves hazardous
substances on site above levels that allow for unlimited use and
unrestricted exposure and no remedial action has taken or will take
place. Since ground water contamination remains at the Site above
levels that allow for unlimited use and unrestricted exposure, EPA will
use the five-year review process to ensure protection of human health
and the environment. EPA completed the first five-year review of the
Site on September 30, 2002. In that five-year review, EPA determined
that the immediate threats have been addressed and the actions taken
have been protective of human health and the environment. EPA plans to
complete the next five year review prior to September 30, 2009.
E. Community Involvement
Public participation activities have been satisfied as required in
CERCLA Section 113(k), 42 U.S.C. 9613(k), and CERCLA Section 117, 42
U.S.C 9617. Documents in the deletion docket which EPA relied on for
recommendation of the deletion from the NPL are available to the public
in the information repositories.
V. Deletion Action
The EPA, with the concurrence of the Commonwealth of Pennsylvania,
has determined that all appropriate responses under CERCLA have been
completed, and that no further response actions, under CERCLA, other
than O&M of the existing treatment system which will be completed under
the 1984 PADER Agreement and five-year reviews, are necessary.
Therefore, EPA is deleting the Site from the NPL.
Because EPA considers this action to be noncontroversial and
routine, EPA is taking it without prior publication of a notice of
intent to delete. This action will be effective February 14, 2005
unless EPA receives adverse comments by January 13, 2005 on a parallel
notice of intent to delete published in the Proposed Rule section of
today's Federal Register. If adverse comments are received within the
30-day public comment period on the proposal, EPA will publish a timely
withdrawal of this direct final notice of deletion before the effective
date of the deletion and the deletion will not take effect. EPA will
prepare a response to comments and continue with the deletion process
on the basis of the notice of intent to delete and the comments already
received. There will be no additional opportunity to comment.
