[FRL-6969-7]
National Oil and Hazardous Substances Pollution Contingency Plan;
National Priorities List
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final deletion of the Salem Acres Superfund Site from
the National Priorities List.
-----------------------------------------------------------------------
SUMMARY: EPA--New England is publishing a direct final deletion of the
Salem Acres Superfund Site (Site), located in Salem, Massachusetts,
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 deletion is being published by EPA with the
concurrence of the Commonwealth of Massachusetts, through the
Department of Environmental Protection (MADEP) 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 July 23, 2001
unless EPA receives adverse comments by June 21, 2001. 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 Elaine Stanley, Remedial Project
Manager, U.S. Environmental Protection Agency--New England, One

I. Introduction
EPA--New England is publishing this direct final notice of deletion
of the Salem Acres 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 July 23, 2001 unless
EPA receives adverse comments by June 21, 2001 on this document. If
adverse comments are received within the 30-day public comment period
on this document, 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 the procedures that EPA is
using for this action. Section IV discusses the Salem Acres 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 release 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 has
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, 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
will 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. In the case of this
Site, a five year review is not necessary since all hazardous
substances, pollutants and contaminants have been removed from the
Site. 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 the 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 Massachusetts on the
deletion of the Site from the NPL prior to developing this direct final
deletion.
(2) The Commonwealth of Massachusetts 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
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 places copies of the documents supporting the deletion
in the Site information repositories identified.
(5) If adverse comments are received within the 30-day public
comment period on this document, EPA will publish a timely notice of
withdrawal of this direct final 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:
Site Location
The Salem Acres Superfund Site (Site) is an approximately two
hundred and thirty-five (235) acre parcel of land located in the Cities
of Peabody and Salem, Massachusetts. The entire Site is zoned
residential but remains undeveloped. The actual contaminated portion of
the Site was confined to the southernmost thirteen acres of the
property. This area borders a residential area to the south, wetlands
to the east and west and undeveloped upland to the north.
[[Page 28104]]
Site History
The contaminated area consisted of three adjacent and separate
disposal areas. There is a Responsible Party (RP) associated with each
area. The first area where hazardous substances were located consisted
of eight unlined sludge lagoons containing industrial sewage sludge
originating from and disposed of by the South Essex Sewerage District
(SESD), a wastewater treatment plant located in Salem, MA. The second
area containing hazardous substances consisted of a coal fly ash pile
disposed of by the Massachusetts Electric Company (MEC). Disposal
activities by SESD and MEC occurred between the mid 1940's and 1969.
The third and final area containing hazardous substances included an
old landfill and three debris piles (collectively Landfill) which
existed prior to the present ownership of the property. The owner of
the property, Ugo DiBiase Salem Realty Trust (DiBiase) is the RP for
the Landfill. Generation and disposal of the landfill and debris piles
is not known. Although DiBiase did not contribute any waste to the
Site, it was deemed liable by virtue of property ownership and failing
to take any action to minimize exposure to contaminants. Operable Unit
No. 1 includes the entire Site.
EPA conducted two Emergency Removal Actions (ERAs) at the Site, one
in 1987 and one in 1990. EPA funded the first action and a portion of
the second action with SESD performing and funding the remaining
portion of the second action. The first action consisted of lagoon
water removal and disposal, capping the lagoons, constructing a slurry
wall and provide fencing to preclude site access. The second action
consisted drum repacking and storage, fence and gate replacement and
installation of signs.
Remedial Investigation and Feasibility Study (RI/FS)
The SESD completed a site-wide Remedial Investigation (RI) on May
29, 1992. They then conducted a Feasibility Study (FS) which was
completed in June 1992. Results of the RI showed the nature and extent
of contamination and assessed the associated risks from exposure. The
contaminants of concern include polynuclear aromatic hydrocarbons
(PAHs), polychlorinated biphenyls PCBs, dioxins/furans, volatile
organic compounds (VOCs), semi-VOCs (sVOCs), chromium, arsenic,
beryllium, vanadium and thallium. The concentration levels for the
dioxin equivalent 2,3,7,8-TCDD found during the RA were below the
cleanup level of 1 part per billion. The primary exposure pathways for
both existing and future land use (residential) that showed
unacceptable risk include: ingestion, dermal contact and inhalation of
(airborne particulates originating from) sludge, fly ash and
contaminated soil.
The FS developed and evaluated various remedies for each
contaminated area, including RCRA capping, incineration,
immobilization, thermal desorption, solvent extraction, in-situ
vitrification, sludge fixation, excavation and off-site disposal.
Record of Decision Findings
A Record of Decision (ROD) was signed on March 25, 1993. The ROD
required a preferred remedy of soil/sludge fixation, excavation and
off-site disposal at a permitted landfill. Implementation of the
preferred remedy required that certain conditions be met which included
that the waste must be classified as non-hazardous under RCRA before
shipment off-site. If these conditions could not be met, the ROD
required construction of a RCRA cap over the hazardous substances to
minimize possible exposure, implementation of institutional controls
and long term monitoring to assure cap integrity. All areas to be
remediated on Site are identified as Operable Unit No. 1. If the
preferred remedy proved to be feasible, then no institutional controls
or long term monitoring would be required.
On April 11, 1997, EPA issued an Explanation of Significant
Difference (ESD). Based on updated toxicity data regarding carcinogenic
polyaromatic hydrocarbons (cPAHs), EPA recalculated cleanup values for
soils using this new information. The cleanup risk value established in
the ROD for the Site was held constant, providing the same level of
protectiveness. Each cPAH was given a separate cleanup value rather
than a total cPAH value 1.2 parts per million (ppm) provided in the
ROD. In addition, EPA calculated a new cleanup value for beryllium
after a background study was performed. EPA redefined the background
concentration of beryllium in soils as 1.0 ppm and revised the cleanup
level from 0.42 ppm to 1.0. The excess lifetime cancer risk resulting
from exposure to 1 ppm beryllium in soils given the exposure scenario
and assumptions specified in the HRA is 2 x 10-6 which is
consistent with EPA's goal for remedial actions (clean up to within the
acceptable risk range of 1 x 10-4 to 1 x
10-6).
Characterization of Risk
The risk assessment performed as part of the RI for existing and
future use scenarios determined that unacceptable risks exist from
exposure to cPAHs, PCBs, dioxins/furans, VOCs, sVOCs, chromium,
arsenic, beryllium, vanadium and thallium. The primary exposure
pathways for both existing and future land use (residential) that
showed unacceptable risk include: ingestion, dermal contact and
inhalation of (airborne particulates originating from) sludge, fly ash
and contaminated soil.
Response Actions
Each of the three RPs entered into separate Consent Decrees to pay
for past costs expended at the Site, all future costs incurred at the
Site and to perform separate remedial designs (RDs) (SESD and MEC only)
and remedial actions (RAs) for each responsible area. The U.S. Army
Corps of Engineers, on behalf of the EPA, performed the RD for the
Landfill with Fund-lead monies. Just prior to the start of a fund lead
RA, DiBiase entered into a Consent Decree to perform the RA and to
cover certain past and all future costs associated with its cleanup.
All future costs incurred by EPA and DEP for each of the three RD/RAs
were covered by each respective RP. EPA retained the Corps to provide
design review and evaluation, oversight of the remedial actions,
including evaluation of quality assurance/quality control (QA/QC)
procedures, performance standards and verified that the validated data
met the established data quality objectives (DQOs) for each project.
For the first RA, DiBiase excavated approximately 2,000 cubic yards
(cy) of material and disposed of it at an off-site permitted landfill.
During the remedial action, fly ash was shown to be present well into
the landfill. DiBiase removed approximately 1,500 cy of fly ash and MEC
agreed to incur the costs associated with this work. Final site
restoration of the Landfill and debris piles was performed in the
spring of 1996.
MEC commenced RA activities in August 1995 and was substantially
completed but discontinued in December 1995 at the boundary of the fly
ash area and the adjacent wetland. Approximately 11,000 cy of fly ash
and approximately 6,100 cy of adjacent contaminated soils were
excavated and shipped off-site to a permitted special waste landfill
located in New Hampshire. Site restoration was performed in the spring
of 1996.
MEC excavated the remaining fly ash found in the wetlands in August
1999. Approximately 1,000 cy of fly ash was
[[Page 28105]]
removed from the wetland and shipped off-site to an appropriate
landfill. Restoration of the wetland included seeding the slopes with
an appropriate wetland soils and seed mix. A final inspection was
performed on August 18, 1999. This is the date for which all
construction activities were considered complete for the entire Site.
SESD performed treatability tests for the fixation of the sludges
during the pre-design phase. The purpose of fixation was to render any
ignitable sludges non-ignitable. The treatability study shown that the
sludges were non-ignitable and non-RCRA toxic and thus not RCRA-
characteristic hazardous waste. SESD implemented the remedy of
excavation and off-site disposal. The remedial work commenced in
September 1996 and substantially completed in September 1997. Final
site restoration was completed in the spring of 1998. A final site
inspection for the sludge areas occurred on April 29, 1999.
A total of 28,755 tons of sludge were excavated and disposed of
off-site at a permitted solid waste disposal facility located in Maine.
A total of 60,304 tons of soil were excavated and disposed of at a
solid waste disposal facility in Massachusetts. The slurry wall, sludge
lagoon HDPE covers installed during the 1987 ERA and other demolition
debris were also removed and sent to the Massachusetts disposal
facility. A total of approximately 7.5 million gallons of site water
accumulated in the excavated areas were collected and discharged to the
SESD treatment plant for treatment via municipal sewer. The water was
tested regularly to ensure compliance with the plant's pre-treatment
limits. The high volume of water that accumulated in the excavated
areas was due to the occurrence of a hundred year storm event,
unanticipated depth of excavation and contractor delays based on cost
claims with SESD.
Each of the RPs monitored surface water and sediments in the
wetlands prior to and after their remediation. SESD was also tasked to
monitor Site ground water during and after remediation. The last and
final ground water sampling event occurred in May of 1999. The results
showed that ground water was not impacted by any remediation. Ground
water had also not been impacted by past disposal of materials at the
Site.
Cleanup Standards
Remedial action cleanup activities at the Site were consistent with
the NCP, the ROD, the ESD and with each RD/RA Consent Decree and
provides protection to human health and the environment. RD/RA plans
for all phases of construction included a Quality Assurance Project
Plan (QAPPs) and incorporated all EPA and State quality assurance and
quality control procedures and protocols (where necessary). All
procedures and protocol were followed for soil, sediment, water and air
sampling during the RA. EPA analytical methods were used for the
confirmatory and monitoring samples during all RA activities. EPA has
determined that the analytical results, having been Tier III validated,
are accurate to the degree needed to assure satisfactory execution of
each RA, show that the cleanup standards have been met, and are
consistent with the ROD/ESD and the RD plans and specifications.
Operations and Maintenance
The Site has been entirely cleaned up in accordance with the ROD,
the ESD and the three CDs. There will be no need for operation and
maintenance activities at the Site. The Site requires no institutional
controls and now provides for unrestricted use. The Site is zoned as
residential. The landowner has informally suggested that he may build
multi-family residences on the Site but at the time of this writing, no
definitive or formal plans have been made public.
Five-Year Review
No hazardous substances remain at the site above health-based
levels after the completion of all remedial actions. Therefore,
pursuant to CERCLA Section 121(c) and as provided in OSWER Directive
9355.7-02, Structure and Components of Five-Year Reviews, May 23, 1991
and OSWER Directive 9355.702A, Supplemental Five-Year Review Guidance,
July, 26, 1994, five year reviews will not be necessary.
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.
Informal public meetings were held in the neighborhood prior to and
after each remedial action. Representatives from EPA, MADEP and the RPs
with their consultants and contractors were present. These meetings
proved to be extremely helpful in providing the public, especially the
immediate neighborhood residents who would be most affected, with
important information regarding activities associated with each
remedial action. These meetings were also particularly useful for the
agencies and the RPs in hearing and addressing the residents' concerns
regarding on-site and off-site activities. Some examples of what the
agencies and the RPs implemented as a result of these meetings
included: prohibiting truck traffic before 8 a.m. and after 5 p.m. and
during school bus pickup and drop off periods; setting a speed limit of
15 m.p.h. for all site-related vehicles on residential streets; daily
street cleaning; air monitoring at the site gate adjacent to the
neighborhood and the RPs agreeing to repave the neighborhood roadway
used to transport wastes off-site.
V. Deletion Action
The EPA, with concurrence from the Commonwealth of Massachusetts,
has determined that all appropriate responses under CERCLA have been
completed, and that no further response actions, under CERCLA 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 become effective July 23, 2001
unless EPA receives adverse comments by June 21, 2001. If adverse
comments are received within the 30-day public comment period on this
document, EPA will publish a timely withdrawal of this direct final
deletion before the effective date of the deletion and it will not take
effect and, 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.
