DESCRIPTIONS OP 29 SITES PLACED ON THE FINAL
NATIONAL PRIORITIES LIST IN NOVE»ER 1989
This document consists of descriptions of 29 sites, including 27 Federal
facility sites, placed on the National Priorities List (NPL) in November 1989.
Sites are arranged alphabetically by State and by site name. Also included as
an addendum is the description of a final Federal facility site that has been
expanded.
The size of the site is generally indicated, based on information
available at the time the site was scored using the Hazard Ranking System.
The size may change as additional information is gathered on the sources and
extent of contamination.
Remedial Actions Under Superfund
The Superfund program is authorized by the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980 (CERCLA) and the Superfund
Amendments and Reauthorization Act (SARA), enacted on October 17, 1986. Under
SARA, the Hazardous Substances Superfund pays the costs not assumed by
responsible parties for cleaning up hazardous waste sites or emergencies that
threaten public health, welfare, or the environment. The Superfund program is
managed by the U.S. Environmental Protection Agency (EPA).
Two types of responses may be taken when a hazardous substance is
released (or threatens to be released) into the environment:
o Removal actions, emergency-type responses to imminent threats. SARA
limits these actions to 1 year and/or $2 million, with a waiver
possible if the actions are consistent with remedial actions. Removal
actions can be undertaken by the private parties responsible for the
releases or by the Federal Government using the Superfund.
o Remedial responses, actions intended to provide permanent solutions at
abandoned or uncontrolled hazardous waste sites. Remedial responses
are generally longer-term and more expensive than removals. A
Superfund remedial response can be taken only if a site is on the NPL.
After publishing two preliminary lists and proposing a formal list, EPA
published the first NPL in September 1983. The list must be updated
atleast annually.

-------
The money for conducting a remedial response or removal action at a
hazardous waste site can come from several sources:
o The individuals or companies responsible for the problems can clean up
voluntarily with EPA or State supervision.
o The responsible party or parties can be forced to clean up by Federal
or State legal action.
o A State or local government can choose to assume the responsibility to
cleanup without Federal dollars.
o Superfund can pay for the cleanup, then seek to recover the costs from
the responsible party or parties.
A remedial response under Superfund is an orderly process that generally
involves the following steps:
o Take any measures needed to stabilize conditions, which might involve,
for example, fencing the site or removing above-ground drums or bulk
tanks.
o Undertake initial planning activities to scope out a strategy for
collecting information and analyzing alternative courses of action.
o Conduct a remedial investigation to determine the type and extent of
contamination at the site.
o Conduct a feasibility study to analyze various cleanup alternatives.
The feasibility study is often conducted with the remedial
investigation as one project. Typically, the two together cost
$1 million and take from 9 to 18 months to complete.
o Select the cleanup alternative that:
Protects human health and the environment
Attains Federal and State requirements that are
applicable or relevant and appropriate
Makes maximum use of permanent solutions, alternative
treatment technologies, or resource recovery
technologies
Is "cost effective" that is, the results achieved
are proportional to the cost (tentative working definition)
o Design the remedy. Typically, the design phase costs $750,000 and
takes 6 to 12 months.
o Implement the remedy, which might involve, for example, constructing
facilities to treat ground water or removing contaminants to a safe
disposal area away from the site. The implementation phase typically
lasts 6 to 12 months.
-------
The State government can participate in a remedial response under
>rfund in one of two ways:
Superfund in one of two ways:
o The State can take the lead role under a cooperative agreement, which
is much like a grant in that Federal dollars are transferred to the
State. The State then develops a workplan, schedule, and budget,
contracts for any services it needs, and is responsible for making sure
that all the conditions in the cooperative agreement are met. In
contrast to a grant, EPA continues to be substantially involved and
monitors the State's progress throughout the project.
o EPA can take the lead under a Superfund State Contract, with the State
having an advisory role. EPA, generally using contractor support,
manages work early in the planning process. In the later design and
implementation (construction) phases, contractors do the work under the
supervision of the U.S. Army Corps of Engineers. Under both
arrangements, the State must share in the cost of the implementation
phase of cleanup. EPA'expects this phase to average out at about
$13.5 million per site, plus any costs to operate and maintain the
remedial action.

EIELSON AIR FORCE BASE
Fairbanks North Star Borough, Alaska
Conditions at listing (July 1989); Eielson Air Force Base covers 19,790
acres in Fairbanks North Star Borough, approximately 24 miles southeast of
Fairbanks, Alaska. Since its establishment in 1944, its primary mission has
been to provide tactical support to the Alaskan Air Command.
Within its boundaries, Eielson contains closed and active unlined landfills
extending into ground water, shallow trenches where weathered tank sludge was
buried, a drum storage area, and other disposal or spill areas.
Eielson Air Force Base is participating in the Installation Restoration
Program (IRP), established in 1978. Under this program, the Department of
Defense seeks to identify, investigate, and clean up contamination from
hazardous materials. IRP tests have found lead, arsenic, chromium, copper,
nickel, and zinc in soil in the drum storage area, as well as trans-1,2-
dichloroethylene (trans) and lead above the Federal primary drinking water
standard in shallow on-site monitoring wells. An estimated 9,000 people
obtain drinking water from wells within 3 miles of hazardous substances on the
base.
*
Surface water within 3 miles downslope of hazardous substances at the base
is used for fishing. The base is in the floodplain of the Tanana River.
The Air Force is developing a workplan for a remedial investigation/
feasibility study to determine the type and extent of contamination at the base
and identify alternatives for remedial action. The workplan is scheduled to
be completed in the fall of 1989.
Status (October 1989): EPA, the Air Force, and the State of Alaska are
negotiating an Interagency Agreement under CERCEA Section 120 for oversight of
activities at the base.

WILLIAMS AIR FORCE BASE
Chandler, Arizona
Conditions at listing (July 1989): Williams Air Force Base (WAFB) covers
4,127 acres approximately 30 miles southeast of Phoenix, Arizona, in Maricopa
County, near Chandler. The base is surrounded by irrigated farmland or desert.
Since the base was constructed in 1941, it has served as a training facility,
primarily pilot training. Industrial activities at WABB have included heavy
maintenance of aircraft and ground equipment in support of pi lot training.
WAFB is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defeise seeks to
identify, investigate, and clean up contamination from hazardous materials. As
part of IRP, the Air Force has identified a number od oot- >i:ially contaminated
areas, including Fire Protection Training Area No. 2, which covers
approximately 8.5 acres near the southern boundary of the base. Prior to 1948,
the area was used as a parking apron. From 1948 until the late 1960s, it was
an unlined pit where large quantities of the combustible liquid waste generated
at WAFB were burned as part of fire training. Any flammable materials
remaining infiltrated the soil or evaporated. These materials included waste
fuels, oils, lubricants, cleaning solvents, and some paint stripper. Starting
in 1983, a concrete liner was installed under the burn pits; however, overflow
is still allowed to seep into the ground. In September 1986, an Air Force
contractor found lead in soil, and in March 1987 found lead in monitoring wells t
on the base.
The Southwest Drainage System (SWDS) has operated since the base was
constructed in 1941. It received plating shop rinse water containing chromium,
cadmium, and copper; aircraft washing wastes consisting of rrethyl ethyl ketone,
toluene, polyurethane, paint thinners, and sludges; fuel; lubricants; hydraulic
fluid; and spills from flight line and maintenance operations. SWDS soil
samples taken in October 1984 contained lead, chromium, and cadmium. SVDS
drains into a storm water retention pond in the southwest corner of the base.
In 1988, the Air Force installed a concrete lining in part of SWDS. WAFB
housing is within 100 feet of SWDS.
A 34-acre landfill in the southwest corner of the base operated during
1941-76, accepting primarily trash and garbage. However, unknown quantities of
hazardous waste were dumped along with the household wastes. In April 1987,
lead and cadmium were detected in monitoring wells, including one between the
landfill and SWDS and adjacent to the pond that received SWDS wastes.
WAFB has four wells that supply drinking water to an estimated 3,400
employees. One of the wells is 1,500 feet from the contaminated well at the
landfill.
The Air Force has completed an initial asses:T.n-jnt of the base and is
developing a workplan for a remedial investigation/feasibility study (RI/FS) to
determine the type and extent of contamination and identify alternatives for;
remedial action. Field investigations are underway,
Status (October 1989): The Air Force is continuing to develop the RI/FS
workplan and has installed a few additional monitoring wells.

BARSTCW MARINE GORES LOGISTICS BASE
Barstow, California
Conditions at listing (July 1989); The Barstow Marine Corps Logistics Base
is in San Bernardino County, California. It is in the Mojave Desert and
adjacent to the Mojave River. A portion of the base, the 1,568-acre Nebo Area,
is approximately 1 mile east of the City of Barstow. It has been used for
maintenance, repair, and rebuilding of supplies and equipment for the Marine
Corps since 1942. Solvent wastes, including trichloroethylene (TCE), were
apparently generated in substantial quantities in the Nebo Area facility. Due
to the lack of records, the quantities of solvents used, stored and discharged
on-site are unknown. The same activities were conducted at the 1,681-acre
Yermo Area, 6 miles east of Nebo.
Barstow Marine Corps logistics Base is participating in the Installation
Restoration Program (IRP), established in 1978. Under this program, the
Department of Defense seeks to identify, investigate, and clean up
contamination from hazardous materials.
Monitoring wells at both Nebo and Yerbo are contaminated with TCE,
according to tests conducted in 1984-85 as part of IRP studies and by the U.S.
Geological Survey. Public wells within 3 miles of hazardous substances at the
base supply drinking water to an estimated 28,700 residents of the City of *
Barstow and outlying areas.
The Marine Corps has completed an initial assessment/site inspection and
is planning a remedial investigation/feasibility study to determine the type
and extent of contamination and identify alternatives for remedial action at
both the Nebo and Yermo areas. An activated carbon system for treating
contaminated drinking water wells at Yerbo is scheduled to be installed in July
1989.
Status (October 1989); The activated carbon system is now operating.

CAMP PENDLETQN MARINE CORPS BASE
San Diego County, California
Conditions at listing (July 1989); The Camp Pendleton Marine Corps Base
encompasses approximately 125,000 acres in San Diego County, California. The
installation is bordered by the City of San Clemente to the north, the City of
Oceanside to the south, and the City of Fallbrook to the east. The base has
served as a training base since its establishment in 1941. Industrial and
other support operations have generated hazardous wastes, including waste oils,
contaminated fuels and other petroleum products, cleaning solvents, and
pesticide rinsate.
Camp Pendleton is participating in the Installation Restoration Program
(IRP), established in 1978. Under this program, the Department of Defense
seeks to identify, investigate, and clean up contamination from hazardous
materials. As part of IRP studies, the Navy identified a number of potentially
contaminated areas, including eight areas where wastes containing DDT,
heptachlor, 2,4-T, lindane, zinc, lead, trichloroethylene, methyl ethyl ketone,
benzene, and xylene had been deposited.
Ground water is shallow, averaging 7-14 feet deep, and soils are
permeable, conditions that facilitate movement of contaminants into ground
water. The 40,000 people living and working on the base obtain drinking water *
from wells within 3 miles of hazardous substances on the base. The nearest
well is within 1,320 feet of one of the disposal areas. To date, no
contaminants have been detected in the camp's water supply.
The San Margarita River, Las Flores Creek, and San Mateo Creek empty into
coastal wetlands within 2 miles of Camp Pendleton. Surface waters within 3
miles downstream are used for recreational activities. Critical habitats for
three birds designated as endangered by the U.S. Fish and Wildlife Service are
within 1 mile of the camp.
The Marine Corps has completed a site inspection and is about to start
planning for a remedial investigation/feasibility study (RI/FS) to determine
the type and extent of contamination at the base and identify alternatives for
remedial action.
Status (October 1989); The RI/FS is underway.

MARCH AIR FORCE BASE
Riverside, California
Conditions at listing (July 1989): March Air Force Base (MAFB) covers
approximately 7,000 acres near Riverside in the Moreno Valley in Riverside
County, California. MAFB is adjacent to light industrial, agricultural, and
residential areas. Established in 1918 as the Alessandro Aviation Field, MAFB
has served as a training base and refueling operations base. Industrial
operations (including aircraft maintenance and repair) involved use of solvents
and disposal of solvent wastes.
MAFB is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous substances.
As part of IRP, the Air Force investigated 28 potentially contaminated disposal
areas. MAFB Well No. 1 on-base was found to be contaminated with
trichloroethylene, tetrachloroethylene, and cis-l,2-dichloroethylene at levels
that exceed State drinking water standards. It was taken out of service.
Soils on the base are contaminated with toluene and benzene. An estimated
11,600 people obtain drinking water from municipal wells within 3 miles of
hazardous substances on MAFB.
The Air Force is conducting a remedial investigation/feasibility study
(RI/FS) to determine the type and extent of contamination at the base and
identify alternatives for remedial action.
Status (October 1989); Field work continues on the RI/FS.

TREASURE ISLAND NAVAL STATICN-HUNTERS POINT ANNEX
San Francisco, California
Conditions at listing (July 1989); Hunters Point Annex of Treasure Island
Naval Station, formerly the Hunters Point Naval Shipyard, encompasses 936 acres
(522 acres dry land and 414 acres submerged in San Francisco Bay) in the
southeast corner of San Francisco, California. Established in 1869, the
shipyard was the first privately owned dry dock on the Pacific Coast. The Navy
first used the installation in 1919 to construct, maintain, and repair ships,
and in 1939 purchased it from California Dry Dock Co. Triple A Machine Shop
leased the facility from the Navy during 1976-87, subleasing numerous
buildings to private tenants. The Navy regained possession of the shipyard
from Triple A in 1987, but continues the subleasing. Operations of the
facility over many decades generated a wide variety of solid and liquid wastes,
including paints, solvents, fuels, acids, bases, metals, PCBs, and asbestos.
Hunters Point Annex is participating in the Installation Restoration
Program (IRP), established in 1978. Under this program, the Department of
Defense seeks to identify, investigate, and clean up contamination from
hazardous materials. The Navy has identified a number of potentially
contaminated areas, including Industrial Landfill, Bay Fill Area, Pickling and
Plating Yard, Battery and Electroplating Shop, Old Transformer Storage Yard,
Power Plant, Oil Reclamation Ponds, Tank Farm, numerous spill areas, and areas *
leased by Triple A. These areas are potential sources of contaminant
migration into ground water and into San Francisco Bay. In the past, wastes
and waste water were directly discharged into San Francisco Bay.
Benzene, PCBs, toluene, and phenols have been detected in on-site ground
water in IRP tests conducted in 1987. A bottling company draws ground water
from springs within 3 miles of hazardous substances on the annex. The company
serves 19,000 people.
Sediments contain elevated levels of heavy metals and polyaromatic hydro-
carbons. Area surface waters are used for recreational activities, commercial
navigation, and fishing.
The Navy is continuing IRP studies and has undertaken some interim cleanup
measures.
Status (October 1989); Wbrkplans for additional interim measures are being
developed. Sampling is underway as part of a remedial investigation/
feasibility study to determine the type and extent of contamination at the site
and identify alternatives for remedial action. Sampling is scheduled to
continue into 1991.

TRAVIS AIR FORCE HASE
Solano County, California
Conditions at listing (July 1989): Travis Air Force Base covers 5,025
acres in Solano County, California. The base is 3 miles east of the City of
Fairfield. The area around the base is primarily agricultural. Established in
1943, the base is near one of the largest and busiest bases in the Military
Airlift Command. It consists largely of runways and related installations.
Industrial operations include various shops where aircraft components were
cleaned with solvents.
Travis Air Force Base is participating in the Installation Restoration
Program (IRP), established in 1978. Under this program, the Departnent of
Defense seeks to identify, investigate, and clean up contamination frcxn
hazardous materials. As part of IRP, the Air Force has identified a number of
potentially contaminated areds, including three landfills used during 1943-77,
of which one (Landfill No. 3) was used for disposal of crushed and rinsed
oesticide containers, as well as the rinsate; areas where combustible wastes
were burned for fire fighting exercises from 1943 to the mid-1970s; a pit where
about 250 pounds of cyanide were buried in about 1967; a solvent spill area
where methyl ethyl ketone, toluene, and tetraethylene glycol dimethyl ether may
'vwe been spilled during paint stripping operations; and the storm sewer
system, one of the most contaminated portions of the base, where chemical
wastes from the various shops were dumped throughout the history of the base. <
The old decommissioned sewage treatment plant is also of concern because
cracked oxidation ponds may have contaminated the ground water below with
pesticides and industrial chemicals,
Endrin, benzeie, 1,1,1-trichloroethane, tetrachloroethylene, and 1,1-
dichloroethane were detected in monitoring wells in different parts of the
base, according to a 1986 IR? report-. An estimated 400 people obtain drinking
water from wells within 3 miles of hazardous substances on the base; the
nearest well is 3,400 feet from the base.
1,1,1-Trichloroethane, benzene, chlorobenzene, 1,1,2,2-tetrachloroethane,
and trans-l,2-dichloroethylene were detected in the storm sewers, according to
the 1986 IRP report, and chlorobenzene was detected in Union Creek, which is
routed through the base via the storm drain system. A spill of jet fuel in
1978 killed all aquatic wildlife along 2 miles of Union Creek. The creek
flows 1.1 miles to Hill Slough, which is a branch of Suisun Marsh, a major
coastal wetland. Because Hill Slough is tidally influenced, any contamination
can reach San Francisco Bay and the Pacific Ocean. Suisun Marsh is widely used
for various recreational activities and is a major stop for migratory birds on
the Pacific Flyway.
The Air Force has completed an initial assessment of the base and is
currently working on a remedial investigation/feasibility study (RI/FS) to
determine the type and extent of contamination and identify alternatives for
remedial action. The RI/FS report, scheduled to be released in the summer of
1989, was delayed to permit further investigation into the cause of a "swelling
affliction" noted in horses and in humans in contact with horses in a grazing
area of the base.
Status (October 1989}; Work on the RI/FS report continues.

AIR FORCE PLANT PJKS
Waterton, Colorado
Conditions at listing (July 1989): Air Force Plant PJKS covers 464 acres
in the foothills of the Rocky Mountains, northwest of Waterton, Jefferson
County, Colorado, approximately 20 miles south-southwest of Denver. Sino-.o
1957, the JIant has assembled missiles (Titan I, II, and III), tested engines,
and conducted research and development. Chlorinated organic solvents were
frequently used, to clean equipment and piping, and fuels containing hydrazine
vet- developed, purified, and tested in support of the Titan III program.
The site is surrounded by an appa^'int^ly 5,200-acre property owned by
Martin Marietta Co., which was proposed for the NPL in September 1985 as
Martin Marietta (Denver Aerospace). The site was dropped from the NPL in
October 1989. Since 1956, Martin Marietta has developed missiles and missile
components for the Me Force. Its production, testing, and storage facilities
are located southeast of and at a lower elevation than the Air Force property.
Air Force Plant PJKS is participating in the Installation Restoration
Progr-aTn (IRP), established in 1978. Under this program, the Department of
Defense seeks to identify, investigate and clean up contamination from
hazardous materials. As part of IRP, the Air Force has investigated a number
of potentially contaminated areas on the plant, including these five: the
Deluge Containment Pond, a 2-million-gallon concrete-lined surface impoundment
that receives water potentially contaminated with hydrazine from rocket engine
testing; D-l landfill, which accepted construction debris, household wastes,
and unspecified chemical wastes until 1974, when it was closed and covered; and
three areas where hydrazine-contarrunated water and trichloroethylene (TCE) were
spilled. Monitoring wells near the contaminated are-is contain TCE,
1,1,1-trichloroethane, and Freon 113, according to IRP tests conducted in
1988. Denver's Kassler Water Trentaent Plant maintains two shallow wells 1.8
miles from contaminated monitoring wells. Water from the wells was previously
blended with other water sources for distribution to the Denver Water
Department's more than 1 million customers. Because of the potential for
contamination and other reasons, the Kassler plant and the two wells havt> -lot
been used routinely since 1986, but are maintained on emergency standby basis.
The 1986 tesf-.<; -il'jo identified TCE and cis-l,2-dichloroethylene in Brush
Creek, which flows from the plant 1.8 stream miles to the South Platte River.
The South Platte is used for r«;ceational activities.
Sludge dredged from the containment pond was piled directly on the ground.
Because the piles, which contain chromium, are uncovered, sedii^it can be
washed into Brush Creek.
As part of IRP activities, the Air Force has prepared a draft remedial
investigation/feasibility study, which determines the type and extent of
contamination at the plant and identifies alternatives for remedial action.
EPA is reviewing the draft report.
Status (October 1989): EPA, the Air Force, and the Colorado Department of
Health are negotiating a Interagency Agreement under CRRCLA Section 120
covering further studies and remedial activities at the plant.

CECIL FIELD NAVAL AIR STATION
Jacksonville, Florida
Conditions at listing (July 1989); The Cecil Field Naval Air Station
covers 20,099 acres in rural southwest Jacksonville, Duval County, Florida.
Established in 1941, the facility is now composed of Cecil Field Proper (9,516
acres), Yellow Water Weapons Area (8,091 acres), and the Outlying landing Field
(2,492 acres). Cecil Field's mission is to provide facilities, services, and
material support for the operation and maintenance of naval weapons and
aircraft for the Sea Based Antisubmarine Warfare Wings, Atlantic. Tasks
performed at this facility include operation of fuel depots, maintenance and
repair of aircraft and engines, and special weapons support.
Cecil Field is participating in the Installation Restoration Program
(IRP), established in 1978.. Under this program, the Department of Defense
seeks to identify, investigate, and clean up contamination from hazardous
materials. As part of IRP, the Navy in July 1985 identified 18 disposal areas
located throughout the base, including landfills, lagoons, waste piles, burn
areas, and spill areas. The majority of them received spent solvents, paint
wastes, and wastes containing chromium and lead. Both soil and water in the
surface and subsurface were potentially contaminated. The Navy then set up a
program of soil and water sampling for 10 of the disposal areas. During this
program, a 19th disposal area was discovered. *
Three aquifers underlie Cecil Field: the surficial, which is used
primarily for irrigation and fire fighting; the intermediate or "shallow
rock," which supplies water to an estimated 2,200 people via private wells
within 3 miles of the disposal areas; and the Floridan, which is the major
water source for Cecil Field. The private wells are threatened because no
continuous clay layer has been found above the shallow rock aquifer.
The major bodies of surface water on Cecil Field are Yellow Water Creek and
its tributaries, Caldwell Branch, Sal Taylor Creek, and Rowell Creek, which is
dammed to form lake Fretwell. Fresh water wetlands are within 450 feet of one
of the disposal areas.
The Navy plans to conduct further site investigations of releases and
contaminant migration under a permit issued under Subtitle C of the Resource
Conservation and Recovery Act (RCRA) incorporating corrective action.
Status (October 1989); EPA is reviewing a Navy workplan to fulfill
requirements for a remedial investigation under CERdA and a facility
investigation under RCRA.

JACKSONVILLE NAVAL AIR STATION
Jacksonville, Florida
Conditions at listing (July 1989): The Jacksonville Naval Air Station
(NAS) is in southwestern Duval County, in Jacksonville, Florida. NAS occupies
approximately 6 square miles on the shore of the St. Johns River near the
headwaters of the Ortega River. The area around the station is commercial and
residential. Since 1940, NAS's primary mission has been to provide services
and materials to support aviation activities.
NAS is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous materials. As
part of IRP, the Navy used historical records, aerial photographs, field
inspections, and personnel interviews to identify at least 40 potentially
contaminated areas within the facility boundaries, including landfills, storage
areas, lagoons, and spills. Wastes handled include waste solvents, oil and
fuel, paint wastes, aqueous wastes containing heavy metals, acids, caustics,
cyanide, paint stripper wastes containing chlorinated solvents and phenolics,
radium paint wastes, and waste from medical radiological programs.
In August and September 1983, a Navy contractor sampled soils and shallow
ground water. Contaminants identified included trichloroethylene, 1,1- «
dichloroethylene, 1,1,1-trichloroethane, tetrachloroethylene, PCBs, cadmium,
chromium, lead, copper, and mercury. The potential exists for contaminated
ground water to migrate off-site and endanger local water supplies. Private
wells into shallow ground water within 3 miles of hazardous substances at the
site provide drinking water to an estimated 300 people.
Hazardous waste was deposited directly into the St. Johns River on NAS. A
1986 IRP report indicates that lead, chromium, and cadmium were found in the
river, which is used for recreational activities within 3 miles downstream of
NAS. Fresh water wetlands and critical habitats for the Florida manatee and
the bald eagle, both designated as endangered species by the .U.S. Fish and
Wildlife Service, are on NAS.
The Navy has taken interim measures to control runoff of oil and solvents
from the old main dump into St. Johns River. The Navy also plans further
investigation of releases of hazardous substances and their migration under a
permit issued under Subtitle C of the Resource Conservation and Recovery Act
and incorporating corrective action.
Status (October 1989)r IRP activities continue.

PENSAOOIA NAVAL AIR STATION
Pensacola, Florida
Conditions at listing (July 1989): The Pensacola Naval Air Station (NAS)
covers approximately 6,500 acres on a peninsula in southern Escambia County,
southwest of the City of Pensacola, Florida. NAS is bounded on the north by
Bayou Grande and on the east and south by Pensacola Bay. NAS has been an
industrial operations center since the early 1800s. Based at the station are
various housing, training, and support activities, as well as the Naval Air
Rework Facility (NARF), a large industrial complex for the repair and overhaul
of aircraft engines and frames; the Naval Aviation Depot, which maintains and
rebuilds aircraft; and the Navy Public Works Center Pensacola, which provides
overall operational support for NAS. Other activities are essentially training
cornmands. Outlying areas include landing fields, the Naval Reservation, Corry
Field, and Saufley Field.
NAS Pensacola is participating in the Installation Restoration Program
(IRP), established in 1978. Under this program, the Department of Defense
seeks to identify, investigate, and clean up contamination from hazardous
materials. Under IRP, the Navy has identified 34 areas potentially containing
hazardous waste. Some are now inactive and are largely without records. Solid
wastes have been disposed of primarily at two landfill areas, one west of a
golf course and the other north of Chevalier Field. Liquid wastes from NARF *
operations were discharged to storm sewers until 1973, when an industrial sewer
system and waste water treatment plant were installed. Other activities
involving hazardous substances include pesticide application, transformer
storage, and firefighting training. Spills or releases of plating wastes,
organic solvents, waste paints and thinners, PCBs, and insecticides have been
documented.
Benzene and ethyl benzene are present in monitoring wells near the golf
course, according to a 1986 IRP report. An estimated 15,000 people on NAS
Pensacola and 30,000 customers of Peoples' Water Co. obtain drinking water from
wells within 3 miles of hazardous substances on the site.
Surface water within 3 miles of hazardous substances on the site is used
for recreational activities.
As part of IRP, the Navy plans to further investigate releases and
contaminant migration under a permit issued under Subtitle C of the Resource
Conservation and Recovery Act and incorporating corrective action.
Status (October 1989); EPA is reviewing a Navy workplan to fulfill
requirements for a remedial investigation under CERCIA and a facility
investigation under RCRA.

MARINE CORPS IDGISTTCS BASE
Albany, Georgia
Conditions at listing (July 1989); The Marine Corps Logistics Base (MCLB)
covers 3,200 acres in Dougherty County, about 5 miles east of Albany, Georgia.
The base is surrounded by agricultural, residential, and commercial land. The
Marine Corps constructed the facility in the early 1950s and has operated it
since that time.
The main function of the base is to coordinate distribution of supplies to
other facilities on the East Coast. The Central Repair Division rebuilds
vehicles, radars, and other kinds of equipment; the Facilities and Services
Division repairs and maintains the MCLB property and equipment. These
divisions generate a major portion of the hazardous wastes on-site through
electroplating, cleaning, stripping, and painting operations.
From 1957 to 1977, a storm sewer received large volumes of metal plating
solutions and stripping wastes. This sewer drains to a ditch that empties into
the Flint River 4 miles to the west. Since 1977, these wastes have been piped
to an on-site treatment plant or have been shipped off-site for disposal.
Solvents, thinners, paints, sludges, and solid wastes reportedly were discarded
in four on-site unlined landfills. Munitions, chlorine gas cylinders, acids,
solvents, and soil sterilants were buried in an additional landfill in the «
eastern section of the site.
MCLB is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defense seeks to
identify, investigate,and clean up contamination from hazardous materials. A
1983 IRP report indicates that trichloroethylene was detected in monitoring
wells near sludge drying beds. The 4,200 people living on the base obtain
drinking water and 2,200 acres of farmland are irrigated by wells within
3 miles of hazardous substances on the base.
In 1986, a Marine Corps contractor detected DDE, DDT, and PCB in sediments
from the bottom of a drainage ditch into which hazardous substances were
discharged.
In April 1988, MCLB conducted a pump test to aid in the design of a system
to recover and treat contaminated ground water.
The Marine Corps cleaned up the sludge drying beds in accordance with a
permit issued under Subtitle C of the Resource Conservation and Recovery Act
(RCRA). The contaminated materials from the drying beds were removed and
transported to a RCRA-regulated disposal facility. The beds were covered with
a 12-inch concrete cap in October 1988.
Status (October); MCLB plans to begin recovering and treating contaminated
ground water by the end of 1989.

IDAHO NATIONAL ENGINEERING LABORATORY (USDOE)
Idaho Falls, Idaho
conditions at listing (July 1989); The Idaho National Engineering
Laboratory (INEL), now owned by the U.S. Department of Energy (USDOE), covers
890 square miles in southeast Idaho near Idaho Falls. INEL is in parts of
Bingham, Butte, Clark, Jefferson, and Bonneville Counties.
The Atomic Energy Commission set up the National Reactor Testing Station
on the grounds in 1949 to build, test, and operate various nuclear reactors,
fuel processing plants, and support facilities. Earlier, parts of the 890
square miles had been used by the Department of Defense. In 1974, the facility
assumed its present name to reflect the broad scope of engineering activities
it conducts.
INEL consists of a number of major facilities, including these three:
Test Reactor Area (TRA), Central Facilities Area (CFA), and Idaho Chemical
Processing Plant (CPP). Most are operated by one of five contractors. The
prime operating contractor is EG&G Idaho, Inc. All three facilities contribute
contaminants to the Snake River Plain Aquifer and draw water from the aquifer.
Approximately 17,300 tons of hazardous materials were deposited at TRA via a
560-foot injection well extending 100 feet into the Snake River Plain Aquifer
and also into numerous unlined ponds and an earthen ditch. The materials *
included chromiuni-cxintaminated cooling tower blowdown water, waste solvents,
sulfuric acid, radionuclides, and laboratory wastes.
Hexavalent chromium is present in on-site monitoring and drinking water
wells on TRA and CFA, according to 1985 and 1986 reports of the U.S. Geological
Survey (USGS). The Snake River Plain Aquifer is the source of all water used
at INEL and is an important water resource in southeastern Idaho. Over 3,000
people draw drinking water from wells within 3 miles of hazardous substances at
INEL.
Recent testing has identified contamination in additional areas of INEL.
Tests conducted in 1987 by INEL and USGS at the Radioactive Waste Management
Complex indicate that carbon tetrachloride and trichloroethylene (TCE) have
migrated from where they were buried to the Snake River Plain Aquifer and that
transuranic radionuclides have migrated to ground water. In December 1988, TCE
was found in drinking water wells in Test Area North. Workers in the area are
now being supplied with bottled water. USDOE has identified 300 areas that
require additional investigation at INEL.
In July 1987, EPA and INEL signed a Consent Order and Compliance Agreement
under Section 3008(h) of the Resource Conservation and Recovery Act calling for
investigation and cleanup.
Status (October 1989); Negotiations are underway for an Interagency
Agreement under CERdA Section 120 for oversight of activities at INEL.

PORT DEVENS
Fort Devens, Massachusetts
Conditions at listing CJuly 1989); Fort Devens is 35 miles west of Boston,
Massachusetts, at the intersection of four townships: Ayer and Shirley (in
Middlesex County) and Lancaster and Harvard (in Worcester County). The area is
largely rural residential.
Founded in 1917, Fort Devens has as its primary mission the training of
active duty personnel to support various Army units. Fort Devens Sudbury
Training Annex, 12 miles to the southwest, was also proposed for the NPL in
July 1989.
Fort Devens covers 9,416 acres and can be divided into three areas: the
1,013-acre North Post; the 3,247-acre Cold Spring Brook Area, which is in the
central part of the fort; and the 5,156-acre South Post. The first two areas
are separated by West Main Street between Shirley and Ayer; the Cold Spring
Brook area and South Post are separated by State Route 2.
Fort Devens is participating in the Installation Restoration Program
(IRP), established in 1978. Under this program, the Department of Defense
seeks to identify, investigate, and clean up contamination from hazardous
materials. IRP studies have identified 46 potential hazardous waste areas,
including: the 15-acre Explosive Ordnance Disposal (EOD) range (in the South «
Post), where explosives and unusable munitions have been detonated or burned in
open unlined pits since 1979; the 50-acre sanitary landfill (in the North
Post), where household wastes, military refuse, asbestos, construction debris,
waste oil, and incinerator ash have been dumped since the 1930s; and Building
1650, where battery acids, PCBs, pesticides, and solvents have been stored.
Monitoring wells near the sanitary landfill contain cadmium, lead,
mercury, iron, and arsenic, according to tests conducted in 1987 by an Army
contractor. An estimated 21,700 fort employees and Ayer residents obtain
drinking water from wells within 3 miles of the landfill; a Fort Devens well is
1,670 feet from the sanitary landfill.
The 1987 tests also found arsenic, chromium, nickel, and lead in surface
water near the sanitary landfill. An 8-mile section of the Nashua River lies
within the fort's boundaries. The 630-acre Oxbow National Wildlife Refuge is
in the east central portion of Fort Devens on land the Army deeded to the
Department of the Interior in 1973. An 83-acre wetland is in the refuge
northeast of EOD.
IRP activities continue.

OTIS AIR NATIONAL GUARD BASE/CAMP EDWARDS
Falmouth, Massachusetts
Conditions at listing (July 1989): Otis Air National Guard Base (ANGB) and
Carrp Edwards cover approximately 21,000 acres of what is today known as the
Massachusetts Military Reservation (MMR) in Falmouth, Barnstable County,
Massachusetts. The area is sparsely populated. Although the occupants and
property boundaries have changed a number of times since MMR was established in
1935, the primary mission has always been to provide training and housing to
Air Force or Army units.
A review of past and presait operations and waste disposal practices
identified a number of potentially contaminated areas, including eight covering
3,900 acres on the southern portion of MMR. Six are within Otis AMGB: Former
Fire Training Area, Current Fire Training Area, Base Landfill, Nondestructive
Testing Laboratory Leach Pit, Fly Ash Disposal Area, and a plume of
contaminated ground water from a sewage treatment plant. The two remaining
areas, Unit Training Equipment Site (UTES) and Property Disposal Office
Stoirnje Yard, are on Carrp Edwards, which is currently leased to the Army. The
materials associated with the eight areas are fly ash, bottom ash, waste
solvents, waste fuels, herbicides, and transformer oil.
While t-ie Nondestructive Testing Laboratory operated (1970-78), waste
solvents, emulsifiers, penetrants, and photographic developers were deposited ,
in the sanitary sewer system. Effluent from the sewage treatment plant was
discharged into sand beds, where it seeped into ground water. In 1984, the
U.S. Geological Survey detected tcichloroethane, tetrachloroethylene, and
trans-l,2-dichloroethylene in monitoring wells downgradient of the plant. The
plume of contaminated ground water extends 2 miles to the south. In 1983 and
1984, the Air Force detected volatile organic compounds (VOCs) in on-site
monitoring wells near the Base Landfill and Current Fire Training Area. The
Air National Guard and the State have detected VOCs in more than 200 private
wells. Water lines were installed in 1986-87 to the affected residences.
EPA has designated the Cape Cod aquifer underlying MMR as a Sole Source
Aquifer under the Safe Drinking Water Act. The municipalities of Bourne and
Sandwich, as well as the Air Force, have drinking water wells within 3 miles of
hazardous substances at the site. To date, they are not contaminated.
irrigation wells are also within 3 miles. The drinking water of 36,000 people
is potentially threatened.
Ashumet Pond, less than 1 mile downslope of the Dormer Fire Training Area,
is used for recreational activities. A fresh water wetland is 3,600 feet
downstream of the area.
The Air Force is participating in the Installation Restoration Program
(IRP), established in 1978. Under this program, the Department of Defense
seeks to identify, investigate, and clean up contamination from hazardous
materials. The Air Force has investigated Air Force property only. A
corrmittee that represents all service branches on MMR is coordinating a second
investigation that addresses the entire facility.
Status (October 1989): Approxirately 40 "operable units" are in various
stages of evaluation, the majority in the remedial investigation phase.

NAVAL INDUSTRIAL RESERVE ORDNANCE PLANT
Fridley, Minnesota
Conditions at listing CJuly 1989); The Naval Industrial Reserve Ordnance
Plant (NIROP) covers 83 acres in an industrial, commercial, and residential
area in Fridley, Anoka County/ Minnesota. Over 200,000 people live within 3
miles of the site. The Mississippi River is 0.3 mile to the west. NIROP has
produced advanced weapons systems since it was constructed in 1940. FMC Corp.,
NIROP's operating contractor, owns a 50-acre site bordering on the south. It
was placed on the NPL in September 1983 under the name FMC Corp. (Fridley
Plant).
Industrial operations at NIROP generate organic-solvent and heavy-metal
wastes. According to the Naval Facilities Engineering Command, 43 drums of
such wastes were buried at the landfill from the early 1950s to the early
1970s. Analyses conducted by the Minnesota Pollution Control Agency (MPCA)
found that soil and ground water on the site are contaminated with solvents,
including acetone, dichloroethylene, tricnloroethylene (TCE), and methylene
chloride. In 1981, three bedrock wells supplying drinking water to NIROP were
taken out of service because of TCE contamination. Tests conducted by MPCA in
1982 on Fridley municipal well #13 did not detect TCE. An estimated 29,000
people obtain drinking water from public wells within 3 miles of the site.
During 1983-84, the Army Corps of Engineers excavated 43 drums and 1,200 *
cubic yards of soil and transported the materials to EPA-regulated hazardous
waste landfills. The actions were conducted as part of the Installation
Restoration Program (IRP), established in 1978. Under this program, the
Department of Defense seeks to identify, investigate, and clean up
contamination from hazardous materials.
On June 26, 1984, MPCA issued a Request for Response Action calling for
the Navy and FMC to determine the extent of surface water and ground water
contamination, locate any additional disposal areas, and take cleanup action.
In response, a network of monitoring wells was installed to gather information
on patterns of ground water flow and contaminant concentrations. In July-
August 1988, a remedial investigation/feasibility study was completed. EPA has
not yet concurred on the report.
An interim remedial measure is being designed involving pumping of ground
water to the surface and treating it to remove the contaminants.
As of June 1989, NIROP has held three Technical Review Committee meetings
with EPA, MCPA, and local representatives, as well as one public meeting.
Status (October 1989): The Navy is developing an Interagency Agreement
under CERCIA Section 120 covering activities at NIROP.

/ FOREST GLEN MOBILE HOME SUBDIVISION
Niagara Falls, New York
Conditions at listing (August 1989): The forest Glen Mobile Home
Subdivision is located on Lisa Lane, Carrie Drive, T Mark Drive, and Edgewood
Drive in Niagara Falls, Niagara County, New York. The 21-acre site, now
cortprised of 52 mobile homes and 2 permanent residents, is between the
Conrail Foote Railroad Yard to the west and Interstate 190 to the east. An
estimated 150 people occupy the site. Adjacent to the railroad yard is the
New Road Landfill. A residential area is to the east of Interstate 190, and
another is to the south of the site.
Prior to the 1960s, the site was a wooded swa>ijland. Aerial photographs
from the mid-1960s reveal that the area was cleared. During the early 1970s,
low-lying areas of the site were filled with unknown materials. In 1980,
the Niagara County Health Department detected phenolic resins, polyvinyl
chloride resins, rubber by-products, and ash in soil. Concrete refuse and
industrial machinery were scattered throughout the 21 acres, with
concentrated areas in the Carrie Drive and Lisa Lane cul-de-sac. In 1980,
the Health Department excavated 10 to 12 cubic yards of soil contaminated
with phenolic resins from a resident's yard and transported it to a landfill
regulated under Subtitle C of the Resource Conservation and Recovery Act.
Prior to 1973, portions of the site were owned by Michigan-Mayne Realty *
Co. and three individuals; the northern undeveloped portion was owned by the
Power Authority of the State of New York. The site was then purchased by
Niagara Falls USA Campsite Corp., which divided the property and sold trailer
home lots to approximately 50 families between 1979 and the present.
In August 1987, EPA inspected the site and sampled the soil. Analysis of
these and subsequent samples detected high levels of aniline, phenothiazine,
benzothiazole, 2-mercapto-benzothiazole, and polyarorratic hydrocarbons. Most
of which are used in manufacturing rubber additives.
In May 1989, EPA used CERCLA emergency funds to remove the crushed
remnants of 108 rusted barrels from a vacant area north and east of the
subdivision. The materials have been secured and sampled pending disposal.
On August 3, 1989, the Agency for Toxic Substances and Disease Registry
(ATSDR) of the U.S. Department of Health and Human Services issued an
advisory warning that the site poses a signifJcant threat to public health
because of possible contact with contamit idted soils and wastes. Under
Section 300.66(b)(4) of the National Contingency Plan, the Federal
regulation by which CERCLA is implemented, a site can be placed on the NPL if
(1) a public health advisory has been issued recommending that people be
removed from the site, (2) EPA determines that the site poses a significant
threat to public health, and (3) EPA anticipates that it will be more cost-
effective to use its remedial authority(available only at NPL sites) than its
emergency removal authority to respond to the site.
Status (October 1989); EPA is arranging for temporary relocation of all-
subdivision residents.

PIATTSBURGH AIR FORCE BASE
Plattsburgh, New York
Conditions at listing (July 1989): The Plattsburgh Air Force Base (PAFB)
covers 3,440 acres in Clinton County, New York. The base is bordered on the
north by the Saranac River and the City of Plattsburgh. Lake Champlain is to
the east and the Salmon River borders the base on the south. The base was
activated in 1955 to serve as a tactical wing in the Strategic Air Command.
Ever since, the base has generated hazardous and potentially hazardous wastes
by industrial shop operations, maintenance of aircraft, painting, fire fighting
exercises, discharging of munitions, and spills. Contaminants generated
include PCBs, methyl ethyl ketone (MEK), trichloroethylene (TCE),
dichlorobenzene (DCB), methylene chloride, and other organic solvents.
Hazardous wastes were deposited in unlined landfills and burned in unlined
pits.
Toluene, TCE, 1,1,1-trichloroethane, methylene chloride, and 1,2-
dichloroethane are present in ditches draining areas where solvents and jet
fuels were spilled. Tests conducted in 1987 found MEK, TCE, and trans-1,2-
dichloroethylene in two shallow monitoring wells downgradient of a drum storage
area. An estimated 2,000 people obtain drinking water from private wells
within 3 miles of a base landfill.
The Air Force is conducting field investigations which include sampling of *
soil, ground water, and surface water at several areas cited during a 1985
records search of hazardous waste and spill areas.
PAFB is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous materials.

RADIUM CHEMICAL CD., INC.
New York City, New York
Conditions at listing (August 1989); The Radium Chemical Co., Inc. (RCC)
Site consists of a one-story brick building at 60-06 27th Avenue in a densely
populated residential and commercial area in Wbodside, Queens Borough, New
York City, New York. Established in Manhattan in 1913, RCC transferred
operations to Woodside in the late 1950s. An unrelated firm occupies part of
the building, sharing a common wall with RCC.
Initially, RCC produced luminous paint for watch dials and instruments.
Later it manufactured radium-containing needles and other sealed devices
(largely for cancer therapy) for lease or sale to hospitals and research
laboratories. Over the past 20 years, safer techniques involving cobalt and
cesium have been developed, significantly reducing the use of radium devices.
In 1983, the New York State Department of labor suspended RCC's operating
license because of various disposal and safety infractions, and in 1986, the
company was denied permission to resume operations. In 1987, the State
ordered RCC to remove the radium and decontaminate the building. The owner
said he could not afford the cleanup and abandoned the operation, leaving a
large number of sealed containers, some of which appeared to be leaking
radium and radon gas. The radium-226 present was estimated to be 110 curies.
Also on the site were hundreds of containers of laboratory chemicals, many *
reactive, corrosive, flammable, and potentially shock sensitive.
Elevated levels of radiation have been measured inside certain areas of
the building. On February 10, 1989, the Agency for Toxic Substances and
Disease Registry of the U.S. Department of Health and Human Services issued
an advisory warning that the RCC site poses a significant threat to public
health because of the possible release of radium-226. Under the National
Contingency Plan, the Federal regulation by which CERCIA is implemented, a
site can be placed on the NFL if (1) a public health advisory has been issued
recommending that people be removed from the site, (2) EPA determines that
the site poses a significant threat to public health, and (3) EPA anticipates
that it will be more cost effective to use its remedial authority (available
only at NPL sites) than its emergency removal authority to respond.
The advisory discusses two concerns. One is that an intruder might enter
the RCC site from the adjacent firm (as has happened in the past) and remove
radioactive materials. The second concern is a serious accident. The U.S.
Department of Energy's Lawrence Livermore Laboratory modelled scenarios
involving a gasoline tanker accident on the Brooklyn-Queens Expressway, 15
feet east of the site. The estimated 27,000 people living within 1 mile of
the site could be exposed to any radiation released.
In July 1988, at the request of the State, EPA undertook a limited
removal action using CERCIA emergency funds. EPA provided 24-hour security
and took measures to stabilize the site. In April 1989, EPA began removing
the radioactive and hazardous materials to approved disposal facilities.
Status (October 19891: EPA completed removing materials from the site in
October 1989 and is determining how to decontaminate and dismantle the RCC site.

FEED MATERIALS PRODUCTION CENTER (USDOE)
Fernald, Ohio
Conditions at listing (July 1989); The Feed Materials Production Center
(FMPC), operated by the U.S. Department of Energy (USDOE), is 20 miles
northwest of Cincinnati in the unincorporated town of Fernald, Ohio. The
1,450-acre site is in both Hamilton and Butler Counties. Generally, the area
is rural, with a number of farms surrounding the site. The Production Area
covers approximately 136 acres in the center of FMPC. Waste disposal areas are
present at locations surrounding the Production Area within approximately
3,000 feet of the center of FMPC.
Since the early 1950s, FMPC has manufactured metallic uranium fuel
elements, target cores, and other uranium products for use in production
reactors originally operated for the Atomic Energy Commission and now for
USDOE. These processes have generated large quantities of wastes, including
low-level radioactive wastes, mixed hazardous and radioactive wastes, waste
oils, waste solvents, and significant amounts of fly ash. Among the materials
on-site are uranium, mercury, barium, thorium, tetrachloroethylene, arsenic,
and PCBs.
Disposal practices and operational deficiencies have resulted in
contamination of soil, ground water, surface water, and air. Major sources of
contaminants include the Production Area, six waste pits, three waste storage *
silos, a storm sewer outfall to Paddy's Run (an intermittent stream), and an
effluent line discharging into the Great Miami River. Uranium contaminates the
Buried Valley Aquifer, the sole source of drinking water for FMPC workers and
most area residents, according to routine monitoring conducted in 1984 by FMPC.
The contamination has resulted in closing of a downgradient private well. An
estimated 1,100 FMPC employees obtain drinking water and 750 acres of land are
irrigated by wells within 3 miles of FMPC.
In 1985, FMPC detected high concentrations of uranium, technetium-99,^ and
hexavalent chromium in the effluent line discharging to the Great Miami River,
which is used for recreational activities within 3 miles downstream.
Radon gas was detected in the atmosphere by on-site monitoring equipment
in April 1986.
USDOE is investigating FMPC under its Comprehensive Environmental
Assessment and Response Program. An environmental survey has been completed at
FMPC, and a remedial investigation/feasibility study (RI/FS) is underway to
determine the type and extent of contamination and identify alternatives for
remedial action.
Status (October 1989); Work on the RI/FS continues.

MOUND PLANT (USDOE)
Miamisburg, Ohio
Conditions at listing (July 1989); The Mound Plant encompasses 306 acres
within the southern city limits of Miamisburg, Montgomery County, Ohio. Mound
is bounded by an urbanized area to the north and east, rural/farmland to the
south, and a railroad right-of-way to the west. Mound has operated since 1948
in support of U.S. weapons and energy programs, with an emphasis on small
explosive components and nuclear technology. First operated by the Atomic
Energy Commission, it is operated now by the U.S. Department of Energy (USDOE).
The facility employs 2,200 people, most of whom reside in the nearby Miamisburg
and Dayton areas.
Mound consists of two elevated areas divided by a small valley which runs
in a TOrtheast-southwest direction through the site. The major waste areas are
on the south slope and valley of the northwest elevated area and include a
landfill in which solvents, paints, and photoprocessing and plating bath
solutions were deposited; several leach beds used to dispose of solutions
containing radionuclides and/or explosive/pyrotechnic materials; and an area in
which a solution contaminated with plutonium was spilled. The landfill
operated from 1948 into the mid-1970s, and one or more of the leach beds
operated at least 15 years. The operating life and the quantity of wastes
deposited are unknown for the majority of the other waste areas. *
The Buried Valley Aquifer (BVA) underlies a portion of the valley area of
the plant and is made up of relatively permeable outwash sand and gravel
deposits. Miamisburg municipal wells are within 3 miles of the site and serve
an estimated 17,000 people. There is some evidence indicating that tritium,
plutonium, and volatile organic compounds contaminate ground water, and that
plutonium contaminates surface water. A system of ditches, canals, and ponds
carries surface water from the facility to the Great Miami River approximately
1 mile downstream. The river is used for recreational activities.
Mound has a permit to discharge to surface water under the National
Pollutant Discharge Elimination System. Mound acquired Interim Status under
Subtitle C of the Resource Conservation and Recovery Act when USDOE filed Part
A of a permit application.
Mound has been evaluated under Phase I (which involves record searches and
preliminary assessments) of the USDOE Comprehensive Environmental Assessment
and Response Program. Phase II studies to confirm contamination are underway.
Status (October 1989); EPA and USDOE are negotiating an Interagency
Agreement under CERCXA Section 120 for oversight of activities at the Mound

DAVISVTLLE NAVAL CONSTRUCTION BATTALION CENTER
North Kingstown, Rhode Island
Conditions at listing (July 1989); The Davisville Naval Construction Battalion
Center (NCBC) is 18 miles south of Providence in North Kingstown, Washington
County, Rhode Island. The area is primarily single-family residential. A military
installation since World War II, the site assumed its current name in 1951. Its
primary mission is to provide mobilization support to Naval construction forces.
NCBC consists of four areas: the Main Center located on Narragansett Bay; West
Davisville Storage area located 3 miles west of the Main Center; Camp Fogarty, a
former training center located 4 miles west of the Main Center; and the
decommissioned Naval Air Station Quonset Point to the south of the Main Center,
which was given to the Rhode Island Port Authority in 1974. The Navy has disposed
of wastes in all four areas.
NCBC is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous materials. Under
IRP, the Navy has identified at least 24 areas potentially containing hazardous
substances. The Navy's investigations are focusing priinarily on two areas: the
Allen Harbor landfill in the Main Center, which received solvents, paint thinners,
degreasers, PCBs from transformers, sewage sludge, and contaminated fuel oil during
1946-72; and the Calf Pasture landfill, which received "decontaminating agents" and
various other contaminants.
Several of the 24 potentially contaminated areas are no longer owned by the
Navy and are being investigated by the Army Corps of Engineers' former facility
program. The primary area the Corps is investigating is the Cairp Avenue landfill,
which is part of the decommissioned Naval Air Station Quonset Point. During
1943-53, the landfill accepted drums of wastes, battery casings, and other wastes.
Ground water is shallow (2-4 feet in some areas) and soils permeable,
conditions that facilitate movement of contaminants into ground water. An
estimated 27,000 people obtain drinking water from public wells within 3 miles of
hazardous substances on the site.
IRP studies conducted in 1986 identified lead, cadmium, silver, mercury, and
chromium in soil from the shoreline and sediments of Allen Harbor, which is a small
inlet from Narragansett Bay. Clams are harvested from Allen Harbor. A fresh water
wetland is adjacent to the Camp Avenue Landfill.
Status (October 1989): A remedial investigation is underway to determine the
type and extent of contamination at the site. A draft report on the work is
scheduled to be completed in mid-1990.

NEWPORT tfAVAL EDUCATION AND TRAINING CENTER
Newport, Rhode Island
Conditions at listing (July 1989): The Naval Education and Training Center
(NETC) is spread along 6 miles of the western shoreline of Aquidneck Island,
north of Newport, Newport County, Rhode Island. NETC facilities are also on
Gould Island, west of Aquidneck Island. NETC covers 1,439 acres. Prior to 1973,
it covered 2,692 acres.
The Navy has used Aquidneck Island as a refueling depot since 1900.
Additional fuel facilities were built during World War II, as were a supply
station, barracks, farms, and a fire fighting training school. After the war, a
number of research and development facilities and training centers were set up.
NETC is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous .naterials. IRP
studies identified numerous potentially contaminated areas, including the
following. The 6-acre McAllister Point Landfill, along the shore of Narragansett
Bay, from 1955 to the mid-1970s accepted wastes consisting primarily of domestic
refuse, spent acids, solvents, paint, waste oil, and PCB-contaminated oil.
Similar wastes were deposited at the 10-acre Melville North Landfill, located in
a low-lying, wetland area along the shore of the bay. It was used from World War
II to 1955 and sold to Melville Marine Industries/Hood Enterprises around 1984. *
Also in the Melville North area are two waste oil disposal areas: a sludge bed
at an old sewage treatment plant, where oil was disposed of foe 6 .ninths, and two
buried fuel tank farms. Another three tank farms are within 0.25 mile of the
bay. Sludge from the farms was dumped on the ground or burned in chambers.
On Gould Island is a disposal area on a steep embankment along 200 yards of
the west shoreline. Wastes disposed of included domestic trash, scrap metal,
wood, pipes, rusted drums, two diesel fuel tanks, and concrete blocks, and
possibly electroplating and degreasing wastes. In 1982, 10 drums, contents
unknown, were removed from a bunker which was later demolished. The disposal
area is in the southwest portion of the island within 100 feet of Narragansett
Bay. This portion of the island is now under State control and is accessible to
the public by boat. The Gould Island Electroplating Shop produced wastes similar
to those deposited at the disposal area. The wastes probably were dumped into
the bay. The shop is not accessible to the public.
Lead and copper are present in monitoring wells in McAllister Point Landfill,
according to a 1986 IRP report. An estimated 4,800 people obtain drinking water
and 220 acres of land are irrigated from private wells within 3 miles of
hazardous substances at the site.
Sediments collected from Narragansett Bay just off the shoreline of
McAllister Point Landfill contain lead, copper, and nickel, according to the
1986 report. Surface water and

SAVANNAH RIVER SITE (USDOE)
Aiken, South Carolina
Conditions at listing (July 1989); The Savannah River Site (SRS), formerly
known as the Savannah River Plant, has produced nuclear materials for national
defense on a 192,000-acre site near Aiken in Aiken, Allendale, and Barnwell
Counties, South Carolina, since 1951. First operated by the Atomic Energy
Commission, it is now operated by the U.S. Department of Energy (USDOE). The
area around SRS is heavily wooded and ranges from dry hilltops to swampland.
SRS operations generate a variety of radioactive, nonradioactive, and mixed
(radioactive and nonradioactive) hazardous wastes. Past and present disposal
practices include seepage basins for liquids, pits and piles for solids, and
landfills for low-level radioactive wastes.
According to a 1987 USDOE report, shallow ground water on various parts of
the site has been contaminated with volatile organic compounds (degreasing
solvents), heavy metals (lead, chromium, mercury, and cadmium), radionuclides
(tritium, uranium, fission products, and plutonium), and other miscellaneous
chemicals (e.g., nitrates).
Contamination has been found in the A-Area Burning/Rubble Pit, where
degreasers and solvents were deposited during 1951-73. In 1985, trichloro-
ethylene (TCE) was detected in nearby monitoring wells. Soil in the A-Area
Miscellaneous Chemical Basin, which reportedly received drums of waste
solvents, also contains TCE. The 3,200 residents of Jackson, South Carolina,
receive drinking water from wells within 3 miles of hazardous substances on
SRS.
A small quantity of depleted uranium was released in January 1984 into
Upper Three Runs Creek, according to USDOE. The creek and all other surface
water from SRS flow into the Savannah River, which is a major navigable river
and forms the southern border between South Carolina and Georgia. Along the
banks of the river is a 10,000-acre wetland known as the Savannah River Swamp.
A March 1987 USDOE report indicates the swamp is contaminated with chromium,
mercury, radium, thorium, and uranium, which overflowed from an old seepage
basin.
USDOE is investigating SRS under its Comprehensive Environmental
Assessment and Response Program. Under the program, USDOE is developing plans
for studying several contaminated areas. Also, USDOE will close some areas on
SRS and conduct postclosure monitoring under a permit issued under Subtitle C
of the Resource Conservation and Recovery Act. RCRA facility investigations
are also being conducted under the corrective action requirements of the RCRA
permit
Status (October 1989); USDOE investigations continue.

OAK RIDGE RESERVATION (USDOE)
Oak Ridge, Tennessee
Conditions at listing (July 1989): The Oak Ridge Reservation (ORR),
operated by the U.S. Department of Energy (USDOE), cavers about 58,000 acres
in Oak Ridge, in Anderson and Roane Counties, Tennessee. The area around the
reservation is predominately rural except for the City of Oak Ridge
(population 28,000). ORR consists of three major operating facilities: Oak
Ridge National Laboratory, a research lab that includes nuclear reactors,
chemical plants, and radiosotope production labs; Oak Ridge Gaseous Diffusion
Plant, a production complex previously engaged primarily in the enrichment of
uranium-235; and the Y-12 Plant, located immediately adjacent to the City of
Oak Ridge, which produces nuclear weapon components, processes nuclear
materials, and performs other related functions.
ORR operations generate a variety of radioactive, nonradioactive, and
mixed (radioactive and nonradioactive) hazardous wastes, many of which in the
past were disposed of or stored on-site. Leakage from inactive disposal and
storage facilities, coupled with spills and other accidental releases, has
contaminated many areas in and around ORR.
Metals, organics, and radionuclides have been detected in ORR soil,
ground water, and surface water. At present, ground water contamination
appears confined to ORR.
A 1983 study by USDOE estimates that 733,000 pounds of elemental mercury
were released to the environment in the 1950s and 1960s around the Y-12
Plant. Most of the contamination around Y-12 is confined to the upper 10
feet of soils and fill. Additional studies revealed that some 170,000 pounds
of mercury are contained in the sediments and floodplain of about a 15-mile
length of East Fork Poplar Creek (EFPC), which has its headwaters at Y-12,
and that some 500 pounds of mercury annually leave this watershed. Mercury
and cesium-137 have been detected at higher than background levels in
sediments of the Clinch River and the Tennessee River near Chattanooga, some
118 miles downstream of ORR. Seven water intakes in this 118-mile stretch
provide drinking water to an estimated 43,200 people. Wetlands in the Blyth
Ferry Water Fowl Management Area are also near the 118-mile stretch of the
river.
EFPC flows through the City of Oak Ridge, exposing people to mercury-
contaminated soils in the easily accessible areas of the floodplains of the
creek. USDOE has removed soil at several locations along the creek where
mercury concentrations were particularly high.
USDOE is investigating ORR under its Comprehensive Environmental
Assessment and Response Program. Under the program, USDOE is conducting
studies involving requirements of CERCLA and of permits issued under Subtitle
C of the Resource Conservation and Recovery Act (RCRA). The permits call for
closing some units on ORR, conducting postclosure monitoring, and evaluating
over 500 solid waste management units under RCRA Sections 3004(u) and (v).
Status (October 19891; USDOE investigations continue.

MONTICELLO MILL TAILINGS (USDOE)
Monticello, Utah
Conditions at listing (July 1989): The Monticello Mill Tailings Site
cavers 78 acres at the southern edge of Monticello in San Juan County, Utah.
The area is in a sparsely populated part of southeastern Utah. The property to
the south is controlled by the Bureau of Land Management. The U.S. Department
of Energy (USDOE) now owns the site.
The mill opened in 1942, recovering vanadium from the uranium/vanadium
ores of the Colorado Plateau. The Atomic Energy Commission, predecessor of
USDOE, bought the site in 1948, recovering uranium until the mill closed
permanently in January 1960. In subsequent years, the two agencies took
various actions to dismantle the mill, stabilize the piles of tailings, clean
up the ore-stock pile areas, and demolish and bury the mill foundation.
Ore processing activities at the mill generated large quantities of mill
tailings that now cover approximately 68 acres. These tailings were segregated
into four discrete piles on the basis of content and mill process: the
carbonate pile, vanadium pile, acid pile, and east pile. The potentially
radioactive contaminated materials (mill tailings and contaminated soils) total
approximately 1.6 million tons, according to a 1984 USDOE report. In 1961, the
tailings piles were covered with soil and revegetated. At least two piles have*
no liners.
The site is underlain by a shallow alluvial aquifer, which is contaminated
with arsenic (0.19 mg/1), selenium (0.16 mg/1), uranium (12.8 mg/1), and
vanadium (4.7 mg/1), according to a 1988 USDOE report. Within 3 miles of the
site, municipal and private wells tapping a deeper aquifer provide drinking
water to an estimated 1,900 people. A municipal well is less than 1,200 feet
from the tailings piles. Montezuma Creek, which flows through the middle of
the tailings piles, is also contaminated with arsenic, selenium, uranium, and
vanadium, according to the 1988 USDOE report. The levels of some contaminants
exceed water quality standards. The creek is used for irrigation within 3
miles downstream of the site.
Radon was present in the air near the piles in tests conducted in 1983-84
by a USDOE contractor. The nearest residential area is approximately 1,000
feet from the tailings piles, and agricultural land starts at 1,700 feet.
USDOE is investigating the site under the Formerly Utilized Site Remedial
Action Program. Under a CERCLA Section 120 Federal facility agreement among
EPA, USDOE and the State, USDOE is required to investigate and clean up the
site to meet CERCIA standards.
Status (October 1989): EPA has commented on USDOE's draft report on a
remedial investigation/feasibility study to determine the type and extent of
contamination at the site and identify alternatives for remedial action. The
final report is expected shortly.

BQNNEVTLLE POWER ATMZNISTRATION ROSS COMPLEX (USDOE)
Vancouver, Washington
Conditions at listing (July 1989): The Bonneville Power Administration (BPA)
Ross Complex has occupied approximately 200 acres in a residential area in Clark
County north of Vancouver, Washington, since 1939. It became part of the U.S.
Department of Energy (USDOE) when the department was established. Ross Complex
serves as the control center for generation and transmission of electricity
throughout the Pacific Northwest.
According to a preliminary assessment made in 1986 by BPA, a number of storage
and disposal areas pose a potential threat, including: DOB-1 Drainfield, where
laboratory wastes were deposited; the Cold Creek Fill Area, where soil potentially
contaminated with oil, PCBs, and heavy metals was disposed of; and the Fog Chamber
Disposal Area, where capacitors containing PCBs were buried in trenches.
In 1987 and 1988, BPA sampled an on-site well; analyses detected chloroform,
1,1-dichloroethane, and 1,1,1-trichloroethane. An estimated 105,000 people in
Vancouver obtain drinking water from public wells within 3 miles of the site.
Cold Creek is 450 feet downslope of the site. It is fed by shallow ground
water that flows under the Ross Complex. Vancouver lake, 1.5 miles from Cold
Creek, is used for fishing and other recreational activities. *
In June 1988, USDOE completed a site inspection of the Ross Complex.
Status (October 1989); BPA is selecting a contractor to conduct a remedial
investigation/feasibility study to determine the type and extent of contamination
at the site and identify alternatives for remedial action.

FORT LEWIS LOGISTICS CfcNl'EK
Tillicum, Washington
Conditions at listing (July 1989); The Fort Lewis Logistics Center has
operated on about 650 acres southeast of Tillicum, Pierce County, Washington,
since 1942. The area around the center is military and residential. Its
primary mission is to maintain, repair, and store military supplies.
Trichloroethylene (TCE) and trans-l,2-dichloroethylene (trans) are used as
solvents at several locations and stored inside or adjacent to buildings.
Until the 1970s, waste TCE and sludge containing TCE and petroleum were
disposed of directly into the ground at three known areas in or adjacent to the
center, which is in the northeast portion of the 86,500 acres occupied by Fort
Lewis. Fort Lewis (landfill No. 5) was placed on the NFL in July 1987.
Fort Lewis is participating in the Installation Restoration Program (IRP),
established in 1978. Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous materials.
In 1986, IRP studies detected TCE and trans, as well as low levels of 1,1-
dichloroethylene, 1,1,1-trichloroethane, and 1,1-dichloroethane, in monitoring
wells at the center. A plume of ground water in the shallow unconfined
aquifer is contaminated with TCE. The plume extends toward Tillicum
approximately 2 miles downgradient of the southern edge of the center, measures *
2,500 feet wide, and reaches at least 80 feet below the water table, which is
at 5-20 feet below the surface. A plume of trans similar but slightly smaller
is also present. The TCE plume passes within 100 feet of a public well serving
Tillicum. The lower aquifer is also contaminated with TCE, according to tests
conducted in 1988 by the Army. An estimated 46,000 people obtain drinking
water from wells within 3 miles of hazardous substances at the center.
As part of a Memorandum of Agreement signed by Fort Lewis and EPA on May
23, 1987, the Army is conducting a remedial investigation (RI) to determine the
type and extent of contamination at the center. It is scheduled to be
completed in the summer of 1989.
Status (October 1989); The Army has completed the RI for the shallow
aquifer and expects to select a remedy in early 1990; an RI for the lower
aquifer is scheduled to start in 1990.
EPA, the Amy, and the State expect late in the year to sign an Interagency
Agreement under CERCLA Section 120 for oversight of activities at the center.

MASHER AIR FORCE BASE
Sacramento, California
Conditions at listing (October 1984); Mather Air Force Base is located
near Sacramento, Sacramento County, California. Its mission as an air
training command base is to train pilots and act as support for the Strategic
Air Command. This effort includes maintenance of aircraft and other
machinery.
A records search of base operations has located a disposal site in the
Aircraft Control and Warning (AC&W) area of the base. This is the current NPL
site. It is now occupied by the Strategic Air Command Security Police
Headquarters. The Air Force has determined that spent trichloroethylene (TCE)
was disposed of in a pit on the site from about 1958 to 1966. A well near the
site was used for drinking water until October 1979, when it was shut down due
to TCE contamination. The well now provides water for fire protection.
Mather Air Force Base is participating in the Installation Restoration
Program (IRP), established in 1978. Under this program, the Department of
Defense seeks to identify, investigate, and clean up contamination from
hazardous materials. The Air Force has completed Phase I (records search).
Fhase II (preliminary survey) is underway.
Status (July 1987); Fhase II of the IRP for Mather Air Force Base has *
been divided into stages. The first stage investigated the cause and extent
of contamination at three areas on the base, including the AC&W Disposal Site,
considered by the Air Force to have high priority. The second stage
investigated 15 other areas on the base. The third stage, currently in
progress, continues the ground water investigation of Stage 1, with the
drilling of additional monitoring wells and ground water sampling.
Status (June 1989); The Mather Air Force Base (AC&W Disposal Site) was
placed on the final NPL in July 1987. EPA is now proposing to expand this
final site to include the entire base, not just the AC&W Disposal area. The
original site had contaminated portions of the large aquifer near sane base
production wells. Since then, EPA has determined that additional areas of the
base are responsible for further contamination of the aquifer, and may be
responsible for contamination off-base. EPA is requesting comment on the
proposal. The site would be renamed "Mather Air Force Base."
Status (October 1989); EPA received no comment on the proposal. Hence,
the site has teen expanded and renamed "Mather Air Force Base."
