Descriptions of Eight Sites Deleted from the National Priorities List in March 1986


                DESCRIPTIONS OP EIGHT SITES DELETED FROM THE
                   NATIONAL PRIORITIES LIST IN MARCH 1986
     This document consists of descriptions of the eight sites deleted on

March 7, 1986 (51 FR 7934) from  the National Priorities List.  On December 31,

1985 (50 FR 53448), the U.S.  Environmental Protection Agency (EPA) announced

its intention to delete the sites and solicited comments on the action for

a 30-day period.  Earlier, EPA had provided a local coronent period in each

of the eight cormunities  involved.   The sites were deleted because EPA has

determined that no further response is appropriate, in accordance with

section 300.66(c)(7) of the National Contingency Plan, the Federal regulation

under which the Comprehensive Environmental Response, Compensation and

Liability Act is implemented.

       Sites are arranged alphabetically by State and by site.

National Priorities List Site
Hazardous waste site listed under the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA)C'Superfund'
TAPUTIMU FARM
Island of lUtuila, American Samoa

Conditions atlisting (October 1981): The Taputimu Farm Site is on
the Island of l\atuila, Trust Tterritory of American Samoa. The site, part
of an experimental farm owned by the Territory* consists of three
rooms of a farm warehouse and a trailer which have been used in excess of
10 years for storage of unused and out-of-date agricultural chemicals and
pesticides. Approximately 4,000 pounds of hazardous wastes are on-site.
The chemical storage areas are a short distance from a public beach area,
and a primary concern is that these materials could be transported by
flood water to the beach 0.3 miles away. Direct human contact and contami-
nation of drinking water and marine resources used for food are of concern.

This is the top priority site in American Samoa.

Response Actions; In 1982, EPA conducted a remedial investigation/
feasibility study (RI/FS). The materials were found to be improperly
stored within the buildings. Analysis of the materials identified several
pesticides and chlorinated organic solvents. The materials were stored on
a concrete or steel floor of the storage areas and trailer. Soil sampling
and visual examination of the site confirmed that contamination was confined
to the interior floors.

The remedial action alternative selected and implemented at Taputimu
Farm in 1984 involved repacking the chemical/pesticide materials for shipping
to the continental United States for disposal in a facility permitted under
the Resource Conservation and Recovery Act. The remedial action also
included washing down all exposed surfaces of the storage areas with bleach
to ensure deactivation of any residual materials not picked up by sweeping
and vacuuming. Finally, two layers of epoxy paint were applied to the
interior walls and 3 inches of concrete were poured over the existing
floor, thereby eliminating the threat of direct contact. The Government of
American Samoa uses the structure only to store farm equipment and has
placed signs on the building prohibiting food storage. Since all materials
were removed and contaminated surfaces cleaned and sealed, no further
monitoring was conducted. ,

EPA, with the concurrence of the Government of American Samoa, has
determined that all appropriate Fund-financed response under CERCLA has
been completed at the Taputimu Farm Site, and that no further cleanup by
responsible parties is appropriate.

Conditions at listing (October 1981); The PCB Warehouse on Saipan,
Commonwealth of the Northern Mariana Islands, is a temporary shelter
built to store about 1,400 gallons of transformer fluid containing up to
25,000 parts per million of PCBs. The fluid is stored in drums awaiting
shipment or off-site disposal. The storage site is adjacent to the
Philippine Sea, an area subject to tropical storms. PCB contamination
of drinking water and marine resources used for food is of concern.

This is the top priority site in the Northern Mariana Islands.

Response Actions; A remedial invesigation of the site conducted by
EPA in December 1982 revealed the presence of 21 drums of PCB-contaminated
oil and 3 crates of sodiun arsenite. Drums were found to be intact and
there was no evidence of any reported spills or leaks. The transformers
from which the oil had been drained were at the Saipan Headquarters
Building and at the Department of Public Works Yard. There was no indication
of leaks or spills near those transformers.

In 1984, EPA used CERCLA emergency funds to remove the 21 drums of
PCB wastes and 3 crates of sodium arsenite. These were repackaged and
transported to the continental United States for disposal at a facility
meeting the requirements of the Toxic Substances Control Act. The sodium
arsenite was disposed of in the continental United States at a facility
permitted under the Resource Conservation and Recovery Act. Tests confirmed
that no PCB wastes had been spilled during the removal action.

EPA, with the concurrence of the Commonwealth of the Northern Mariana
Islands, has determined that all appropriate Fund-financed response under
CERCLA has been ccrnpleted at the PCB Warehouse Site, and that no further
cleanup by responsible parties is appropriate.
U.S. Environmental Protection Agency/Remedial Response Program

Conditions at listing (September 1983) : Morris Arsenic Dump is an
old gravel pit covering 5 acres in a rural area about 1 mile northeast of
Morris in Stevens County, Minnesota. In the early 1940s, about 1,500
pounds of arsenic-laced grasshopper bait were on the site. Hie subsequent
construction of a highway in the area may have dispersed the bait and
made it difficult to discover the exact burial location.

Tests by EPA have detected arsenic in the shallow ground water.
The City of Morris and private wells in the area draw on shallow ground
water. No drinking water wells have been affected to date.

Response Actions; In 1984, as part of a remedial investigation (RI), EPA
installed 11 monitoring wells around the site and sampled soil in the
site area. The results of the RI indicate that arsenic levels in the
surface soils were all below 7 micrograms per kilogram (:g/kg), well
within the natural background range of 3 to 14. ^g/kg. Arsenic concentrations
in the soils at the water table were somewhat elevated, ranging between
20 and 40..-g/kg, but far below the Centers for Disease Control (CDC)
action level of 100'/g/kg for surficial soils. CDC was consulted with
respect to the soils and concurred that no action was necessary. Samples
from the monitoring wells and nearby domestic sources indicate that
arsenic levels were considerably below the Primary Drinking Water Standard
of 50 micrograms per liter ('..g/1). Arsenic was found to be at or near
3 ','9/1- The municipal well field for Morris is approximately 1 mile in
the opposite direction of ground water flow and would not be impacted by
any contamination at the site. Other domestic wells sampled in the
vicinity did not have arsenic contamination above background.

EPA, with the concurrence of the State of Minnesota, has determined
that the Morris Arsenic Dump poses no significant threat to public health
or the environment and, therefore, taking remedial measures is not appropriate.
EPA has recommended to State, county, and local officials that, as a
further precaution, a notice be placed on the property. The deed notice
would be entered in county land records and state that the site had
previously been used for the disposal of a hazardous substance.

FRIEDMAN PROPERTY
Upper Freehold Township, New Jersey

Conditions at listing (October 1981): The Friedman Property is located
in Upper Freehold Township, Monmouth County, New Jersey. (The site was once
listed under the name "Upper Freehold Site.") The 3-acre site lies just across
the boundary from Plumstead Township and is immediately adjacent to an
unnamed tributary to Lahaway Creek, which is itself a tributary of the
Delaware River, In the late 1950s and early 1960s, free-flowing liquids,
household wastes, and demolition debris were dumped into a natural ditch
and then covered over. Several residences and two trailer parks within
0.3 miles of the site have private wells. Four monitoring wells installed
in 1980 by New Jersey detected heavy metals and a number of organic
pollutants. Organic chemicals were present in an adjacent stream.

Response Actions: In 1984, EPA and the New Jersey Department of
Environmental Protection (NJDEP) completed a remedial investigation/
feasibility study (RI/FS) covering the air, soils, wastes, ground water,
surface water, and adjacent stream sediments. The RI results indicate
that limited contamination is present at the site, and that the site was
not used as a hazardous waste disposal facility. Its wastes were no
different than those of a typical municipal landfill. Air monitoring
during the RI/FS did not show levels above ambient air quality standards,
and no complaints of odors or fumes were received from area citizens
before or during testing, or from personnel conducting the RI/FS.

Ground water testing included the installation of six monitoring
wells and sampling of domestic wells in the vicinity of the site. The
shallow ground water had slightly elevated levels of zinc — below 0.5
milligrams per liter (mg/1) — and 0.03 mg/1 of phenols. These levels are
below current EPA Health Effects Assessment levels of 7.4 mg/1 for zinc
and 3.5 mg/1 for phenols. Analysis of deep ground water revealed only
zinc at levels comparable to surface levels. The only similarity between
the shallow and deep ground water is in naturally occuring zinc.
Since similar chemicals were not found in the two aquifers, and geologic
analysis indicates no interconnections, there is no indication that the
lower aquifer is contaminated or will be in the future.

The RI/FS indicated that the adjacent stream sediments had not been
significantly contaminated by materials found at the site, although trace
contamination consistent with routine road maintenance practices from the
adjacent highway was found.

In summary, the RI/FS concluded that there are no significant sources
of contamination at the site, and contaminants have not migrated from the
site and are not expected to migrate. Therefore, no remedial action was
appropriate.

 National Priorities List Site

 Hazardous waste site listed under the
 Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLAK"Superfund")

       EPA, with the concurrence of the State of New Jersey, determined  that
  the Friedman  Property  Site poses no significant threat to public health
  or the environment and,  therefore, taking remedial measures is not
  appropriate,   Itowever,  EPA the NJDEP have agreed that the shallow aquifer
  in the vicinity of the  site will be monitored as a precautionary measure
  to ensure that current  site conditions do not change.  The State is
  responsible for periodic ground water monitoring for 5 years.  State
  monitoring to date indicates that conditions remain unchanged.

       As an additional precaution, EPA recommended to state, county,  and
  local officials that a  notice be placed on the property deed and the plot
  plan amended.  The deed notice and plot restrictions would be entered  in
  county land records.  Ihey would note that the site had previously been
  used for waste disposal  and restrict on-site excavations, agricultural,
  and residential use.

Conditions at listing (October1981); Between June and August 1978,
over 30,000 gallons of industrial waste containing PCBs were deliberately
discharged along approximately 243 noncontiguous miles of highway shoulders
in 14 counties of North Carolina. In late August, the State covered the
spill areas with activated charcoal and liquid asphalt. Because of the
quantity of soils involved and the distances to approved landfills, the
State decided to construct a new landfill. In December 1978, North
Carolina sought EPA approval for a PCB landfill in Warren County. EPA
approved the landfill site in June 1979, subject to compliance with a
number of technical and procedural conditions.

The State conducted several investigations and feasibility studies
between 1979 and 1981 and ascertained that contamination did not migrate
from the spill areas into surface water, biota, or ground water.

This is the top priority site in North Carolina.

Response Actions; In May 1982, EPA and the State initiated remedial
action to: (1) construct a landfill meeting the requirements of the Ibxic
Substances Control Act for disposal of PCB wastes? (2) remove, transport,
and dispose of contaminated soils; and (3) reconstruct the highway shoulders.
Disposal of contaminated soil was completed in November 1982, and the
landfill was capped, graded, and vegetated.

During soil removal, the beginning and end point of each contaninated
strip were sampled to ensure that contaminated soils were removed.
Random samples were collected after soils were removed. Analyses indicated
that nearly all samples contained 10 parts per million (ppm) or less of
PCBs. No soils with PCBs above 50 ppm were left in place. Excavated
areas were then filled with clean soil.

EPA, with the concurrence of the State of North Carolina, has determined
that all appropriate Fund-financed response under CERCLA at the PCB
Spills Site has been completed, and that no further cleanup by responsible
parties is appropriate. The State is currently monitoring the landfill
constructed to contain contaminated soils removed from the site. The
results indicate that the landfill continues to meet all requirements for
postclosure monitoring.

ENTERPRISE AVENUE
Philadelphia, Pennsylvania

Conditions at listing (December 1982); The Enterprise Avenue Site
covers about 57 acres along the Delaware River in an industrial area of
Philadelphia, Pennsylvania. From 1971 to mid-1976, the city operated the
site as a landfill. Several waste-handling firms buried at least 10,000
drums of hazardous wastes there without the city's permission. During
exploratory excavations in January 1979, the Philadelphia Water Department
discovered approximately 1,700 drums that contained or had once contained
wastes such as paint sludges, solvents, oils, resins, metal-finishing
waste, and solid inorganic wastes. In 1982, the city started cleanup
actions, including removal of drums and soil to a landfill permitted under
the Resource Conservation and Recovery Act (RCRA). A total of 32,800
cubic yards of excavated soil was identified as contaminated with organic
chemicals (toluene, benzene, ethylbenzene, or organic halogenated compounds)
In October 1982, after spending $7 million cleaning up the site, the city
ran out of money. Left on-site were approximately 20,000 tons of contami-
nated soil in two piles that had been partially covered.

Response Actions: In 1984, EPA and the city started to complete the
remedial actions. All of the spockpiled soils were analyzed for a variety
of metals and organic chemicals. Soils were divided into 100-cubic-yard
lots. A Key Indicator Analysis was used to determine which lots would be
disposed of in an off-site facility. If any one indicator exceeded
action levels, the entire soil lot was deemed contaminated and sent
off-site. Action levels for inorganics were selected based upon the
Extraction Procedure Tbxicity lest used to determine if a waste is
hazardous under RCRA. Organic action levels were established using
similar methodology and are consistent with levels that would be used
today. After removal of contaminated soils from the site, the area was
sampled on a grid pattern to ensure that all soils not passing the test
had been transported off-site. The results indicate that the remedial
objectives were attained, and that all soils considered contaminated were
removed. The site was then capped, seeded, and fenced.

EPA, with the concurrence of the Commonwealth of Pennsylvania, has
determined that all appropriate Fund-financed response under CERCLA at
the Enterprise Avenues Site has been completed, and that no further cleanup
by responsible parties is appropriate. The Pennsylvania Department of
Environmental Resources has agreed to operate and maintain the site. The
department has also developed and implemented an operations and maintenance
plan for the cap and will monitor ground water to ensure that water
quality remains at background levels.

LEHIGH ELECTRIC & ENGINEERING CO.
Old Forge Borough, Pennsylvania

Conditions at listing (October 1981); The Lehigh Electric & Engineering
Co. Site, in Old Forge Borough, Lackawanna County, Pennsylvania, occupies
approximately 5.4 acres adjacent to the Lackawanna River. The company
operated a storage and repair facility for electrical equipment from the
mid-1970s until March 1981. On-site are 4,000 pieces of eguipnent, some
contaminated with PCBs. Analyses indicate that extremely high levels
accumulated in the soil due to the indiscriminate disposal of dielectric
fluids containing PCBs. Contamination of ground water and surface water is
possible because the soil is highly permeable and the site is in the Qcodplain.

In April 1981, with funds made available under Section 104 of the Clean
Water Act, EPA fenced the site and analyzed soil and water samples. In
September 1981, using funds made available under the Rasource Conservation
and Itecovery Act, EPA started a remedial investigation/feasibility study
(RI/FS)to determine the type and extent of contamination at the site and
identify alternatives for remedial action.

Response Actions; The RI/FS, completed in 1983, included the analysis
of ground water, air, and river sediment samples, and the evaluation of
cleanup alternatives.

In Phase I of the remedial action, all transformers, transformer
contents, and surface debris were removed from the site. This was completed
in December 1982. In Phase II, contaminated soils and buildings were
removed from the site, which was then backfilled, graded, and vegetated.
These actions were completed in September 1984. Analyses conducted
during excavation showed that the remedial action reduced the concentration
of PCBs in soils to 10 parts per million. Contaminated soils were
transported to a disposal facility meeting the requirements of the
Toxic Substances Control Act.

In May 1985, EPA inspected the site, collected sanples, and verified
that the objectives of the remedial action were met.

After the contaminated soils were excavated, the remaining soils
containing low levels of PCBs were buried beneath 10 to 15 feet of clean
backfill. PCBs are not readily soluble in water so that any PCBs remaining
are not expected to impact ground water; no PCBs were detected in ground
water samples taken during the RI/FS.

EPA, with the concurrence of the Commonwealth of Pennsylvania, has
determined that all appropriate Fund-financed response under CERCLA at
the Lehigh Electric & Engineering Co. Site has been completed, and that
no further cleanup by responsible parties is appropriate. The Pennsylvania
Depatanent of Environmental Resources has agreed to perform all future
operation and maintenance, including the continued monitoring of ground
water for PCBs.

PCB WASTES
Trust Territory of the Pacific Islands

Conditions at listing (October 1981); The Trust Territory of the
Pacific Islands, an area larger than the continental United States, has
eight separate areas for storing transformers contaminated with PCBs.
The sites were located on the islands of Koror in the Jtepublic of Palau,
Moen in Truk State, Yap, Kosrae, and two on both Ponape and Majuro. The
storage areas, which hold more than 2,000 gallons of wastes, are unprotected
and could contaminate ground water and surface water used as drinking
water. Contamination of marine resources used for food could also result.
Wastes migrating from sane of these sites may already have contaminated
the surrounding area.

This is the top priority site in the Trust Territory.

Response Actions; A remedial investigation conducted by EPA in
December 1982 revealed that the PCBs in drums and transformers and some
pesticides and chemicals were improperly stored. A previous oil spill
was apparent at one location formerly used to store transformers. In
seme locations, intact containers of transformer oil were in unsecured
areas open to the general public.

In 1984, EPA used CERCLA emergency funds to remove wastes containing
over 50 parts per million (ppm) of PCBs and the other hazardous wastes
found at the various locations. During the removal action, soils and
waste oils were sampled in the field using a portable testing kit that
allowed segregation of wastes for transport. Only the transformer storage
area had contaminated soils. It is located in a fenced in rural area.
Testing was conducted in the area before and after removal of contaminated
soils. No PCBs above 50 ppm were found in structures or soils after
removal.

Fluids containing under 50 ppm of PCBs were blended and burned on the
islands. Other PCB wastes were transported to a disposal facility in the
continental United States meeting the requirements of the Toxic Substances
Control Act. Other hazardous wastes were removed and transported to a
facility in the continental United States permitted under the Resource
Conservation and Recovery Act.

EPA, with the concurrence of the Trust Territory of the Pacific
Islands, has determined that all appropriate Fund-financed response under
CERCIA has been completed at the PCB Wastes Site, and that no further
cleanup by responsible parties is appropriate.
