How to Use the NPL Book
VV
,rn
The site fact sheets presented in this book
are comprehensive summaries that cover a
broad range of information. The fact sheets
describe hazardous waste sites on the NPL and
their locations, as well as the conditions
leading to their listing ("Site Description").
The summaries list the types of contaminants
that have been discovered and related threats
to public and ecological health ("Threats and
Contaminants"). "Cleanup Approach" pres-
ents an overview of the cleanup activities
completed, underway, or planned. The fact
sheets conclude with a brief synopsis of how
much progress has been made in protecting
public health and the environment. The
summaries also pinpoint other actions, such as
legal efforts to involve polluters responsible
for site contamination and community con-
cerns.
The fact sheets are arranged in alphabetical
order by site name. Because site cleanup is a
dynamic and gradual process, all site informa-
tion is accurate as of the date shown on the
bottom of each page. Progress is always being
made at NPL sites, and the EPA periodically
will update the site fact sheets to reflect recent
actions. The following two pages show a
generic fact sheet and briefly describe the
information under each section.
How Can You Use
This State Book?
You can use this book to keep informed
about the sites that concern you, particu-
larly ones close to home. The EPA is commit-
ted to involving the public in the decision
making process associated with hazardous
waste cleanup. The Agency solicits input from
area residents in communities affected by
Superfund sites. Citizens are likely to be
affected not only by hazardous site conditions,
but also by the remedies that combat them.
Site cleanups take many forms and can affect
communities in different ways. Local traffic
may be rerouted, residents may be relocated,
temporary water supplies may be necessary.
Definitive information on a site can help
citizens sift through alternatives and make
decisions. To make good choices, you must
know what the threats are and how the EPA
intends to clean up the site. You must under-
stand the cleanup alternatives being proposed
for site cleanup and how residents may be
affected by each one. You also need to have
some idea of how your community intends to
use the site in the future, and you need to know
what the community can realistically expect
once the cleanup is complete.
The EPA wants to develop cleanup methods
that meet community needs, but the Agency
only can take local concerns into account if it
understands what they are. Information must
travel both ways in order for cleanups to be
effective and satisfactory. Please take this
opportunity to learn more, become involved,
and assure that hazardous waste cleanup at
"your" site considers your community's
concerns.

SITE DESCRIPTION
This section describes the location and history of the site. It includes descrip-
tions of the most recent activities and past actions at the site that have con-
tributed to the contamination. Population estimates, land usages, and nearby
resources give readers background on the local setting surrounding the site.
THREATS AND CONTAMINANTS
The major chemical categories of site contamination are noted, as well as
which environmental resources are affected. Icons representing each of the
affected resources (may include air, groundwater, surface water, soil, and
contamination to environmentally sensitive areas) are included in the margins
of this section. Potential threats to residents and the surrounding environ-
ments arising from the site contamination also are described.
CLEANUP APPROACH
This section contains a brief overview of how the site is being cleaned up.
RESPONSE ACTION STATUS
Specific actions that have been accomplished or will be undertaken to clean
up the site are described here. Cleanup activities at NPL sites are divided
into separate phases, depending on the complexity and required actions at the
site. Two major types of cleanup activities often are described: initial,
immediate, or emergency actions to quickly remove or reduce imminent
threats to the community and surrounding areas; and long-term remedial
phases directed at final cleanup at the site. Each stage of the cleanup strategy
is presented in this section of the summary. Icons representing the stage of
the cleanup process (initial actions, site investigations, EPA selection of the
cleanup remedy, engineering design phase, cleanup activities underway, and
completed cleanup) are located in the margin next to each activity descrip-
tion.
SITE FACTS
Additional information on activities and events at the site are included in this
section. Often details on legal or administrative actions taken by the EPA to
achieve site cleanup or other facts pertaining to community involvement with
the site cleanup process are reported here.

Chandler Landfill
Site Description
Compass Industries (Avery Drive) is a 40-acre permitted landfill located in an abandoned
limestone quarry on a bluff above the Arkansas River in Tulsa. Operating from 1964 to the late
1970s, it served as one of the major municipal landfills in the Tulsa area. The limited records
available indicate that unknown quantities of waste jet fuel, solvents, caustics, bleaches, benzene,
and pesticides were dumped at the site. The waste was piled approximately 14 feet deep. During
the 1970s, poor operating practices and open burning resulted in several fires at the landfill. In
1982, the most recent fire burned underground for more than a year, occasionally breaking out
into the open. The State Health Department began to study air and water quality in 1983, when
residents complained about odors at the site. The site is in a rural area, but is immediately west
of Chandler Park, a recreational area. Citizens were also concerned about a nearby elementary
school. The nearest residence is 1/4 mile from the site, and the nearest drinking water well is 1/2
mile away, although it is upgradient from the site and currently is not in use.
Site Responsibility:
The site was addressed through
Federal, Stale, and potentially
responsible parties' actions.

Threats and Contaminants
/5>
.^>
The soil was contaminated with toxic metals and organic compounds. Contaminants
included oily sludges, jet fuel, solvents, acids, caustics, bleaches, benzene,
polychlorinated biphenyls (PCBs), and pesticides. Soil no longer poses a threat due to
the installation of a clay cap over the contaminated area. The low concentrations of
contaminants in the groundwater are within Federal standards. In the past, the site was
troubled by recurrent fires. Toxic air emissions from burning material threatened
nearby residences. In addition, trespassers from the nearby recreational area were at
risk of coming into contact with contaminated materials, as people have used the site
for target practice; however, the site is fenced now making trespassing unlikely. An
American Bald Eagle habitat near the site has been made safer as a result of site
cleanup efforts.

Cleanup Approach
Response Action Status
Immediate Actions: The EPA installed a fence around the site and put warning
signs around its perimeter in mid-1988.
Source Control: In 1987, the EPA selected the following remedies: installing an
EPA-approved cap over the landfill area to isolate contaminated materials and reduce
the amount of water seeping into and through the landfill; diverting surface water to
reduce overland flows and infiltration; grading the site to encourage site runoff and prevent
erosion; and collecting and treating contaminated shallow groundwater before discharge to the
Arkansas River. The construction phase began in 1989. The clay cap was completed in 1990 and
final seeding of the site took place in 1991. Further sampling of the groundwater showed that the
low levels of contaminant concentrations do not pose a threat to people or the environment.
Therefore, the remedy for groundwater cleanup was canceled. A final site inspection, conducted
in 1991, verified that the cleanup has been effective. In addition, approximately 24 months of
sampling have verified that the cleanup actions are sufficient to protect public health and the
environment. The site is currently in a five-year operations and maintenance phase to ensure that
the site cleanup remedy continues to protect public health and the environment. The EPA expects
to complete a final site review in 1995.
Site Facts: Texaco, Sun Refining & Marketing, and Standard Royalties Liquidating Trust
together performed the cleanup, pursuant to Unilateral Administrative Orders. Cost recovery
efforts are continuing for past EPA expenditures at the site.
Environmental Progress
All construction at the site is complete. The construction of a fence to limit access to the site has
reduced the exposure potential of the Compass Industries (Avery Drive) site. Completion of the
clay cap has contained material on site and surface water diversion techniques will help keep
pollutants from migrating off site. Approximately two stream miles along the Arkansas River
have been made safe from off-site migration of contaminants, allowing continued recreational use
of the area. In addition, 40 acres of land have been returned to the community for recreational
and commercial use.

Site Description
The Double Eagle Refinery Company, located southeast of the intersection of 4th Street NE and
Martin Luther King Avenue, has been in operation since 1929. Until around 1978, this 7-acre
facility re-refined used motor oils by acidulation, distillation, and filtration. Areas of concern
include: a sludge lagoon, six smaller earthen impoundments, and numerous structures and pieces
of abandoned refinery equipment. An inventory done by the site owner in 1990 showed 13 steel
buildings, a fire tube boiler, two heat exchanges, five vacuum precoat/scrapper filters, two
concrete settling cells, and approximately 100 steel tanks of varying dimensions. Although the
equipment appears to be contaminated to various degrees, the tanks are empty. Since the
inventory, the owner has removed some of the equipment from the site. About 36,000 cubic
yards of waste oils contaminated with heavy metals are in surface impoundments on site.
According to the company, the oils come from truck fleets, garages, automobile dealers,
industries, and City, State, and Federal agencies throughout the State. In addition, waste solvents
and other products were collected from major industrial companies in Oklahoma. Approximately
6,100 cubic yards of nearby land have been contaminated. The land use in the area is mixed
industrial-residential. About 28,500 people in Del City and Smith Village obtain drinking water
from public and private wells within 3 miles of the site. The site is located 1/2 mile from a
school and 1/4 mile from a residential area. Surface waters within 3 miles of the site are used for
recreational activities. The North Canadian river is located approximately 1/2 mile south of the
site. The Fourth Street Superfund site is about 500 feet northeast of the Double Eagle Refinery
Company site. Cleanup at both sites may be interrelated as necessary.
Site Responsibility:
This site is being addressed through
Federal and potentially responsible
parties' actions.

July 1995
-------
Threats and Contaminants
Sediments from the ponds and drainage areas, the surrounding soil areas,
groundwater, and surface water are contaminated with barium, lead, zinc, acid base-
neutral compounds, and volatile organic compounds (VOCs). Groundwater in the area
is shallow (10 to 25 feet in some cases) and soils are permeable, conditions that help
contaminants move into groundwater. There is a health risk from direct contact with
the materials, but this has been lessened since the area was fenced. Wetlands are
located adjacent to the site and wildlife in the area includes migratory fowl and small
mammals.
Cleanup Approach
This site is being addressed in two stages: immediate actions and two long-term remedial phases
focusing on controlling the source of contamination and cleaning up the groundwater.
Response Action Status
Immediate Actions: In 1989, the EPA ordered the site owner to fence and post
warning signs over the northern side of the site, so that people and animals could not
come into direct contact with hazardous substances. The fence and signs were erected
in 1989. In early 1994, bird netting was installed over surface impoundments and oily ponds.
Source Control: The EPA began conducting an investigation of the sources of
contamination at the site in 1989. In 1992, after a public comment period, the EPA
selected a cleanup approach that will stabilize contaminants prior to their removal off
the site. The EPA will consolidate approximately 42,000 cubic yards of off-site and on-site
wastes, neutralize consolidated acidic wastes on site, stabilize and solidify wastes containing lead
on site, and dispose of other treated wastes in an appropriate landfill. The technical design for
these efforts is underway and is scheduled to be completed in late 1995.
Groundwater: Investigations to determine the nature and extent of groundwater
contamination and to identify cleanup alternatives began in mid-1992 and were
completed in the summer of 1993. In early 1994, the EPA decided to monitor the
lightly-contaminated groundwater to ensure that the source control efforts are sufficient to prevent
further groundwater contamination. Based on these findings, the EPA will determine if further
cleanup actions are necessary. Design of the monitoring system is currently underway.
Site Facts: An Administrative Order of Consent was issued to Double Eagle in December of
1989 requiring it to fence the site and post warning signs. In addition, the EPA has identified and
is currently in negotiations with more than 40 potentially responsible parties to pay for site
cleanup costs.

Site Description
The Fourth Street Abandoned Refinery is an abandoned 28-acre waste oil reclamation facility that
operated from 1940 to 1968, and comprised numerous oil and sludge disposal pits. More recent
dumping has occurred in the form of old concrete and building materials and government surplus
supplies. An inactive oil well and a gas well are located on site. Elevated levels of semi-volatile
and volatile organic compounds (VOCs) have been identified in soil, sediment, and sludge.
Approximately 32,500 people live within 3 miles of the abandoned refinery. The nearest surface
water body is the North Canadian River, which is approximately 1/2 mile south of the site.
Wetlands are located adjacent to the site, Douglas High School is located about 1/2 mile north of
the site and a residential area is located about 1/4 mile to the northwest. The Double Eagle
Refinery Company site, also on the NPL, is about 500 feet southwest of the Fourth Street
Abandoned Refinery site.

Threats and Contaminants
Soil and sediment samples contain barium, lead, chlordane, pesticides, acids, bases,
and crude oil constituents. Groundwater and sludge from the site are contaminated
with nickel, benzene, and numerous VOCs. Given the hydrogeology of the site, there
is significant potential for groundwater contamination in the two aquifers. The land
drains to the south and east, thus threatening the North Canadian River. Also, the site
was not completely fenced, making it possible for people and animals to come into
direct contact with hazardous substances.
July 1995
-------
Cleanup Approach
This site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on source control and cleanup of the groundwater.
Response Action Status
Initial Actions: In 1985, the State decontaminated junk autos, stored two drums of
benzene, and capped and seeded the area. The EPA fenced the site and posted
warning signs in 1989.
Source Control: Between 1985 and 1987, the EPA performed surveys and field
sampling at the site. The EPA has completed an investigation to determine the extent
of contamination to surface water, sediment, soil, sludge, and tar areas, as well as to
track the movement of contaminants through the air. In late 1992, the EPA selected the following
cleanup measures to control the sources of contamination at the site: cleaning, consolidating,
demolishing or salvaging, and removing contaminated equipment and on-site structures;
consolidating an estimated 42,000 cubic yards of contaminated material on site; neutralizing the
acidic wastes; solidifying wastes containing lead; and disposing of treated wastes in an EPA-
approved landfill. The engineering design for these actions is complete and cleanup is underway.
Cleanup actions are expected to be completed in late 1995.
Groundwater: Investigations to determine the nature and extent of groundwater
contamination and to identify cleanup alternatives began in mid-1992 and were
completed in late 1993. Based on the results of this investigation, the EPA chose to
continue monitoring groundwater contaminant levels to ensure that source control efforts are
effective in preventing further contaminant migration into the lower aquifer. The design for the
monitoring system is underway and is expected to be completed in late 1995.
Environmental Progress
Decontamination of junk autos, confinement of benzene, and capping of the area have reduced
the potential of exposure to contamination at the Fourth Street Abandoned Refinery site, making
it safer while long-term cleanup activities are planned and underway.

Criner/Hardage Waste Disposal
Site Description
The 60-acre Hardage/Criner site was licensed by the State of Oklahoma from 1972 to 1980 to
accept industrial and hazardous wastes such as asbestos, cyanides, and flammable sludges. Pits
excavated to receive wastes filled rapidly; wastes were then transferred to two temporary ponds.
In the west pond, liquid wastes were slurried with soil and transferred to the south pond. When
the south pond filled, wastes were stacked 15 to 20 feet above the ground, becoming a sludge
mound. In the mid-1970s, drums were no longer emptied but were piled at the northern end of
the main pit, called the drum mound. These practices resulted in pesticides, solvents, acids, and
metal sludges contaminating surface water, groundwater, and surface soil. The nearest residence
in this rural area is at the southwestern site boundary. Adjacent to the North Criner Creek flood
plain, the site is surrounded by cattle grazing land. Shallow groundwater from the site has moved
into the North Criner Creek alluvium.
Site Responsibility:
This site is being addressed through
Federal, State, and potentially
responsible parties' actions.
NPL LISTING HISTORY
Proposed Date: 10/23/81
Final Date: 09/08/83
Threats and Contaminants
Solvents, paint sludge, and inks have contributed to the contamination of soil,
groundwater, and surface waters. Contamination found in each area includes: heavy
metals, pesticides, polychlorinated biphenyls (PCBs), oils, and methylene chloride.
Inhalation of dusts and vapors generated from the soils on site poses a potential risk
for workers and trespassers. Fugitive dusts and vapors from on-site soil disruption
could be inhaled off site. A mound on the site may contain over 20,000 drums. There
is no known current use of the groundwater, but any use of contaminated groundwater
would be hazardous.
July 1995
-------
Cleanup Approach
The site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on cleanup of the source area and the groundwater.
Response Action Status
Initial Actions: In 1982, the potentially responsible parties started decontaminating
the site by mixing pit fluids with soil, excavating visibly contaminated soils from
mixing areas and temporary ponds, capping the source areas with a soil cover, and
consolidating wastes in source areas. Between September and November 1987, the potentially
responsible party provided an alternate water supply to residents living southwest of the site. The
parties potentially responsible for contamination fenced the site in early 1988. In 1988, heavy
rains caused slope damage to the western face of the barrel mound. The potentially responsible
parties performed the repair, and restored the other eroded mound areas.
Source Area: In 1986, the EPA chose the following remedies, to be carried out by
the potentially responsible parties: excavation of approximately 180,000 cubic yards
from the principal source areas (the drum mound, main pit, and sludge mound) to the
bedrock; separation of wastes; treatment and disposal of solids in an on-site approved landfill;
incineration of organic liquids; and treatment and disposal of inorganic liquids. A public
comment period was held in 1989 to explore options other than those listed. In 1989, the EPA
revised the 1986 remedy selection. The revised cleanup remedy calls for soil vapor extraction of
the source areas, consolidation of contaminated soils, and removal of contaminated liquids
followed by off-site incineration and capping of the source areas. To date, interceptor wells have
been installed in the southwest area of the site and liquid extraction wells have been installed in
the drum mound and Drum Pit areas. Extracted contaminants will be taken off-site for
incineration. Once all cleanup activities are completed, expected in 1995, the source area will be
capped.
Groundwater: The EPA's selected remedy, which was reviewed by the public in
1989, is to build a V-shaped trench to intercept contaminated groundwater over most
of the site. Another interceptor trench will catch groundwater that is moving into the
alluvium located under North Criner Creek. The captured groundwater will be pumped to an on-
site treatment unit, and then the treated water will be discharged into North Criner Creek. The
groundwater and surface water will be monitored, surface drainage controlled, and the use of
contaminated groundwater prevented through institutional controls. Construction of the
groundwater cleanup remedies is expected to be completed in 1995.
Site Facts: In 1978, the State of Oklahoma filed complaints against the facility for suspected
lead poisoning of the air around the site. A ruling in 1982 found that the potentially responsible
parties were liable for all costs of removal or remedial actions. A complaint was filed against 36
generators and transporters in 1986. A partial Consent Decree was signed by the potentially
responsible parties in 1987 for the groundwater cleanup. In August 1990, the Federal District
Court selected the cleanup remedy proposed by the potentially responsible parties.

miles east of Oklahoma City
Site Description
The Mosley Road Sanitary Landfill covers 72 acres and was used from 1975 to 1987 as a
commercial, residential, and industrial landfill. In 1976, the landfill accepted approximately 2
million gallons of hazardous substances under a Temporary Emergency Waiver for Hazardous
Waste Disposal issued by the Oklahoma State Department of Health. According to the permit
application, pesticides, industrial solvents, sludges, waste chemicals, and emulsions were
deposited into three unlined pits. Since then, the pits have been buried under as much as 80 feet
of solid refuse and fill and a clay cap. In October 1984, Waste Management of Oklahoma, Inc.
acquired the site, operating it until November 1987, when the landfill reached its authorized
capacity. Concerns about groundwater contamination brought the site to the EPA's attention.
Hazardous wastes were disposed of near the base of the landfill; a long-term risk could exist if
wastes leak into the groundwater. The landfill lies above the Garber-Wellington Formation, an
aquifer that serves as a high-quality drinking water source for many Oklahoma City residents.
The surrounding area is both residential and commercial. An estimated 57,000 people obtain
drinking water from public and private wells within a 3-mile radius of the site. Six homes are
located within 1/2 mile from the site and obtain drinking water from private wells.

Entire Site: Under an agreement with the EPA, Waste Management of Oklahoma,
Inc. and Mobile Waste Controls, Inc. conducted a study of the nature and extent of
site contamination and evaluated potential remedies for site problems. The
investigation was completed in 1991. In mid-1992, the EPA selected a cleanup remedy that
includes: restoring groundwater as a potential source of drinking water through natural
attenuation; continuing to monitor groundwater if samples indicate natural dissipation is
ineffective; repairing and improving the existing cap and adding a vegetative soil layer; installing
warning signs; restricting future use of the site; fencing the site; and implementing a landfill gas
monitoring system to prevent explosions. The technical designs for these actions are underway
and are expected to be completed in 1995.
Site Facts: Waste Management of Oklahoma, Inc. and Mobile Waste Controls, Inc. signed an
Administrative Order with the EPA in 1989 to conduct an investigation into the nature and extent
of site contaminants. In early 1994, the EPA issued a Unilateral Administrative Order to Waste
Management of Oklahoma to clean up the site. In addition, the EPA is negotiating with over 40
potentially responsible parties to contribute to the cleanup efforts.
Environmental Progress
The site is now inaccessible due to the fence installed by Waste Management of Oklahoma, Inc.
The installation of a clay cap over the landfill has reduced the potential for exposure to
contaminants while final cleanup measures are being designed.

Washington County
Bartlesville
Other Names:
National Zinc Co.
Horsehead, Inc.
St. Joe Mineral
The National Zinc Corp. site is approximately 150 acres in size and located on the west side of
Bartlesville. The company has conducted zinc smelting operations at the site since 1907. In
1976, National Zinc Corp. was acquired by the Zinc Corporation of America. Air emissions
were essentially uncontrolled until 1976 when old retort furnaces were replaced with an
electrolytic smelting process. Widespread contamination off site, including a large portion of
west Bartlesville and much of the downtown area, has been traced back to the uncontrolled air
emissions of the smelting operations as well as the use of smelter waste for fill projects
throughout the area. Approximately 8 square miles of surface soil surrounding the smelter
facility is contaminated. Contamination also was caused by the use of slag and other smelter
waste as fill materials for a number of years. The site is a mixed residential, commercial, and
industrial area, including schools, day care facilities, and playgrounds, which could potentially be
affected by site contamination. Approximately 5,000 people live within 3 miles of the site. An
estimated 1,700 students attend two schools and three day care centers located nearby which are
known to have contaminated soils. Approximately 170 people work at these facilities.
Site Responsibility:
The site is being addressed through
Federal and potentially responsible parties'
actions.
NPL LISTING HISTORY
Proposed Date: 05/10/93
Threats and Contaminants
Approximately 8 square miles of surface soil is contaminated with the heavy metals
lead and cadmium. According to 1992 EPA reports, lead and cadmium levels in the
top two feet of soil are greater than three times natural background levels.
Concentrations are highest at the smelter and decrease away from the smelter.
Although the extent of the area of contamination has not been fully determined, it
includes soils at two schools and three day care centers. Blood lead studies performed
by the Oklahoma State Department of Health in 1991 and 1992 indicate that
approximately 10 percent of the children in the contaminated area have elevated blood
lead levels. The study revealed that children on the west side of Bartlesville, the side
where the facility is located, had elevated levels of blood lead whereas the children on
the east side did not. People who incidentally touch or ingest contaminated soils could
be at risk.
July 1995
-------
Cleanup Approach
This site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on the cleanup of the entire site.
Response Action Status
Initial Actions: In late 1992, contamination was removed from 29 easily accessible
areas, including schools, day care facilities, and playgrounds. These activities
included excavating contaminated soil, transporting the soil to an on-site staging area,
and backfilling with clean soil. Soil was stabilized at the staging area and then sent to a non-
hazardous commercial landfill. In 1993, the EPA excavated lead- and cadmium-contaminated
soils from 22 residences of individuals with high blood-lead levels, and back-filled the areas with
clean soil. Contaminated soils present at the approximately 260 residences of individuals with
elevated levels of lead in their blood were removed in 1994 by the potentially responsible parties.
Entire Site: After completing a study of the nature and extent of contamination at
the site, the EPA selected final cleanup remedies in late 1994 that included replacing
soil excavated from residential properties and treating contaminated soil at
commercial properties through a combination of capping, backfilling with clean soil, tilling, and
treating contamination with phosphate. The technical designs for these actions are currently
underway and are expected to be completed in 1995.
Site Facts: Contamination within the fenced boundaries of the facility is being addressed under
EPA's Resource Conservation and Recovery Act (RCRA) program. The Superfund program is
addressing contamination outside the fenced boundaries. This site was selected as a Superfund
Accelerated Cleanup Model (SACM) pilot project. Under SACM, site assessment activities are
undertaken to support both early and long-term cleanup actions. Site conditions and their
associated risks are assessed continuously until all necessary data are collected to screen the site
or support any needed response actions. Response actions are initiated once evidence indicates
that early action is warranted. Under SACM, the public is notified early on of the potentially
hazardous conditions of the site. The EPA also gives early notification to polluters of their
potential liability for conducting or paying for cleanup activities. At this site, two potentially
responsible parties agreed to remove the contaminated soil from residential properties as describe
above.
Environmental Progress
By having removed contaminated soil from public and residential areas, EPA has reduced the
immediate threat posed by contaminants at the National Zinc Company site. Further cleanup of
contaminated properties is expected to begin shortly.

Site Description
The 160-acre Oklahoma Refining Company site is an abandoned oil refinery that was active from
1920 to 1984, when Oklahoma Refining Company declared Chapter 11 bankruptcy. The operator
at the site placed process wastes, some reactive or flammable, into approximately 50
impoundments, many of which were unlined. Other wastes were tilled into the soil or placed in a
waste pile. Some process wastes were applied to the soil and treated in a land farming operation.
In 1981, the EPA observed leachate coming from the site, threatening nearby Gladys and
Chetonia Creeks, which are used for recreational activities. In 1984, the owner declared
bankruptcy and abandoned the facility. In 1986, the EPA found an on-site monitoring well to be
contaminated with heavy metals. New owners began operation of the refinery area in the fall of
1993. The Rush Springs Sandstone aquifer, which lies beneath the site, is considered to be a
potential source of drinking water; however, no one is currently drinking water from the
contaminated portion of the aquifer. Approximately 1,600 people obtain drinking water from
public and private wells within 3 miles of the site. One private well is located within 1,000 feet
of the site.
Site Responsibility:
This site is being addressed through
Federal and State actions.
NPL LISTING HISTORY
Proposed Date: 06/24/88

Threats and Contaminants
The ground water is contaminated with heavy metals, including arsenic and lead.
Process wastes from oil refining were tilled into the soil through a landfarming
operation, but the soil contaminants are unspecified. While surface water is not
contaminated, it will be addressed by cleanup activities since often it mixes in with
drinking water supplies. Many of the wastes remaining on site are flammable or
reactive and pose the threat of fire or explosion. The site is unfenced, making it
accessible to people and animals. Gladys Creek, which is adjacent to the site, has been
shown to be affected by contamination from the site. Gladys and Chetonia Creeks are
used for recreation.
July 1995
-------
Cleanup Approach
This site is being addressed in two stages: initial actions and a long-term remedial phase focusing
on cleanup of the entire site.
Response Action Status
Initial Actions: In 1989, the EPA surveyed the site to determine the nature of
emergency actions required. As a result of the survey, a fence was erected to limit
access to the site in 1990. Netting was placed over the impoundments to protect
wildlife, further reducing the risk of direct contact with the hazardous waste. The EPA properly
plugged 23 abandoned wells in 1990 also. Additionally, the 18 drums on the site were disposed
of in late 1991.
Entire Site: In 1989, the Oklahoma State Department of Health (OSDH) began an
investigation to assess the extent of contamination in soil, groundwater, and surface
waters and to identify appropriate cleanup strategies. The cleanup remedy was
selected in mid-1992 and includes: biological treatment of surface waters, recycling of 10,000
cubic yards of asphalt, neutralization of 51,000 cubic yards of acidic and caustic waste deposits,
stabilization of 8,900 cubic yards of metals-contaminated material, and interception and treatment
of groundwater. OSDH has received funds to begin the detailed design of the remedy and is in
the process of selecting a contractor.
Site Facts: The EPA issued an Administrative Order in 1980, requiring the potentially
responsible parties to reduce site discharge to Gladys Creek.
Environmental Progress
Initial cleanup actions to control contamination and to fence the Oklahoma Refining Company site
have reduced the potential for direct exposure to hazardous substances, making the area safer
while cleanup activities are being designed.

d Springs,
ithe Arkansas River
The 200-acre Sand Springs Petrochemical Complex site, located approximately 3 miles west of
the Tulsa city limits, operated as a refinery from the turn of the century through the late 1940s. It
was later developed as an industrial area consisting of chemical manufacturers, solvent and waste
oil recovery operations, transformer salvaging and recycling, and various other industries. The
site contains acid sludge pits, a surface impoundment, spray ponds, and solvent and waste oil
lagoons. The refinery left two, unlined pits about 10 feet deep, containing sulfuric acid sludge
and heavy metals. Over the years, sludge seeped into the Arkansas River levee, releasing
contaminants into the river. Other industries stored or disposed of hazardous substances in
drums, tanks, and unlined pits, or simply buried them on the site. These substances included
volatile organic compounds (VOCs), acids, caustics, chlorinated solvents, and sludges containing
heavy metals. The nearest residence is located on site. Drinking water wells are in use within 1/2
mile, although they are upgradient of the contaminated site.
Site Responsibility:
This site is being addressed by Federal,
State, and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 09/08/83
Final Date: 06/10/86
Threats and Contaminants
The primary contaminants of concern affecting the soil, shallow groundwater,
sediments and sludge are VOCs and heavy metals such as lead and chromium. The
Arkansas River has been shown to be contaminated by past seepage of sulfuric acid
sludges and heavy metals through the levee. Individuals are at risk from direct contact
with or accidental ingestion of contaminated soil, groundwater, or sludges.
August 1995
-------
Cleanup Approach
The site is being addressed in three stages: immediate actions and two long-term remedial phases
focusing on control of the sources of contamination and cleanup of the groundwater.
Response Action Status
Immediate Actions: Under orders from the EPA, parties potentially responsible
for the contamination removed drums and tanks from the site. The EPA also
removed 400 drums of hazardous material, repaired the fence around the site, and
sampled and analyzed the pits, on-site soil, and the on-site monitoring wells.
Source Control: In September 1987, the EPA determined that incineration of the
contaminated soil and sludges was the most efficient remedy for this site. However,
the remedy of solidification or stabilization of wastes proposed during the public
comment period was identified as acceptable if the potentially responsible parties could
demonstrate that these techniques provided comparable protection of public health and
environment. ARCO started the engineering design for the remedy in 1988, including a bench-
scale pilot test to determine the most appropriate solidification technique. In 1991, ARCO
performed further testing of the solidification/stabilization techniques. Based on these results,
solidification/stabilization was selected as the final remedy in early 1993. Design of the remedy
was completed in 1994, and cleanup is underway. Construction of an on-site landfill to contain
remaining sludges is also underway, as is the design of a wastewater treatment plant. By January
1995, all waste at the site had been excavated and neutralized. All cleanup activities are
scheduled to be completed in 1996.
Groundwater: The EPA believes that once the sources of contamination are
removed, groundwater pollution will dissipate naturally over time, via the natural
flushing action of the aquifer. In 1988, following a study by the State, the EPA
selected a "no action" cleanup remedy for the groundwater phase. The groundwater and Arkansas
River water will be monitored for 30 years to ensure the effectiveness of the source control
remedy in protecting the groundwater. In addition to monitoring, signs have been posted,
warning residents of the dangers of coming in direct contact with site contamination.
Groundwater monitoring began in 1990. To date, contamination levels have not been significantly
reduced.
Site Facts: In 1984, the EPA issued two Administrative Orders for drum and tank removal. In
1987, an Administrative Order was issued to the parties potentially responsible for site
contamination, who conducted on-site incineration and solidification treatability studies. A
Consent Decree was signed in 1990 by ARCO, the State, and the EPA for design and cleanup of
site contaminants.

EPA ID# OKD980629844
Site Description
EPA REGION 6
Ottawa County
gh the towns of Miami, Richer,
;din, Quapaw, and Commerce
The Tar Creek (Ottawa County) site covers a 40-square mile portion of the Tri-State Mining
District (Picher Mine Field), which covers 100 square miles. The area produced significant
quantities of lead and zinc from 1900 to 1950. When major mining operations ceased in the early
1970s, groundwater accumulated in the mines. The acid water reacted with the surrounding rock,
causing many of the metals present to dissolve and resulting in high concentrations of zinc, lead,
and cadmium in the water. In 1979, acid mine water with high concentrations of heavy metals
began to discharge to the surface from boreholes and the abandoned mine shafts, contaminating
the surface water in Tar Creek. This problem, along with the potential for contaminating the
drinking water source under the mining area, prompted the U.S. Geological Survey and the State
to investigate the site. In 1981, the State declared the site its number one pollution problem. The
towns of Miami, Picher, Cardin, Quapaw, and Commerce are located within the site area
boundary. The nearby population of approximately 30,000 receives its drinking water from the
Robidoux Aquifer.
Site Responsibility:
This site is being addressed through
Federal and State actions.
NPL LISTING HISTORY
Proposed Date: 10/23/81
Final Date: 09/08/83
Threats and Contaminants
The groundwater, sediments, and surface water were contaminated with heavy metals
including lead, zinc, and cadmium. The upper aquifer was contaminated with heavy
metals. Several people use the upper aquifer as a source of drinking water. The lower
aquifer was threatened due to several boreholes and leaking abandoned wells
connecting the aquifers. The lower aquifer serves several towns and rural communities
including the towns of Miami and Picher. Because the Picher town water well passes
through a highly mineralized rock formation, the high levels of heavy metal
contaminants indicated major casing failure in the well. Runoff of surface waters had
degraded Tar Creek. Wetlands are found on the site and also were subject to
contamination.
July 1995
-------
Cleanup Approach
The site is being addressed in two stages: an initial action and a long-term remedial phase
focusing on contamination at the entire site.
Response Action Status
Initial Action: In 1985, an emergency water supply was put in place by the
National Guard. The EPA plugged the contaminated well using sand and corrosion-
resistant concrete. Backup wells were used to flush the city lines. Subsequently,
water quality in these two wells returned to normal and the National Guard discontinued water
delivery. The EPA drilled the new well, connected it to the water system, and re-tested the
water.
Entire Site: The selected remedies included diverting and diking the two major
inflow areas in Kansas and a third in Oklahoma, plugging aquifer wells, and
developing a monitoring plan. A total of 83 wells were plugged. These cleanup
activities were completed in 1986. The EPA completed a Five Year Review of the site in early
1994. This review resulted in the evaluation of possible sources of lead described below.
Lead Contamination: Over the summer of 1994, the EPA began new investigations
into possible subsurface soil and other contamination in surrounding areas. Iron levels
in drinking water from five community wells in the mining area are elevated above
established standards. The Oklahoma Department of Environmental Quality is investigating to
determine if the Roubidoux Aquifer is the source of contamination. A summary of the results of
the Indian Health Service testing made available to EPA in 1994 indicated that approximately
35% of the Indian children tested in the area had elevated levels of lead in their blood. EPA's
Emergency Response Branch investigated day care centers, schools, and parks in the fall of 1994
for mining waste contamination. Approximately 50% of the samples contained elevated levels of
lead. The Oklahoma Department of Health is planning to screen the children in the mining area
for blood lead poisoning in 1995.
Site Facts: In 1982, the EPA awarded a Cooperative Agreement to the State for a site
investigation and a study of alternative cleanup strategies. The EPA continues negotiations with
numerous potentially responsible parties to recover cleanup costs.
Environmental Progress
Actions by the State of Oklahoma and the EPA have reduced the potential for contaminants in the
shallow groundwater to migrate to deeper drinking water aquifers and have achieved the
groundwater cleanup standards established for the site. The State also has completed cleanup
activities at the Tar Creek (Ottawa County) site for surface water improvement. The EPA
recently began a new investigation into the nature and extent of lead contamination in surface
soils, which is a source of exposure to children living in the area.

Site Description
The 3 1/2-acre Tenth Street Dump/Junkyard site is located in an industrialized area in Oklahoma
City. The site was used as a municipal landfill from 1950 to 1954. It housed a private salvage
yard from 1959 to 1979, accepting such things as paint thinners, used tires, old transformers, and
junk automobiles. During the salvage of electrical equipment, large amounts of polychlorinated
biphenyl (PCB) oil was spilled on the ground. A fire at the site destroyed 1,000 old tires, which
may have contributed to a black tar-like substance on the ruined soil. Workers indiscriminately
bulldozed drums of benzene and methylene chloride onto sections of the site along with other
debris. About 30,000 people draw drinking water from public and private wells within 3 miles of
the site; the nearest is within 1/4 mile. About 1,000 people live within 1 mile of the site.
Residential property is adjacent to the site.

The site is being addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 01/22/87

Threats and Contaminants
The soils have high levels of PCBs. Residents, trespassers, and children are
potentially threatened by direct exposure to contaminated soils and waste left on the
site. The North Canadian River is threatened by contaminated runoff from the site and
erosion of site soils. Contaminants from the soil also may threaten nearby
ground water.
Cleanup Approach
This site is being addressed in two stages: initial actions and a long-term remedial phase focusing
cleanup of the entire site.
July 1995
-------
Response Action Status
Initial Actions: The first phase of the initial action started in 1985 and included
removal of drums of solvents and junk automobiles, and decontamination of the
office building, and tire repair machine shop. After decontamination, workers
backfilled the wash pit. Because contamination was widespread, the entire site was capped to
prevent rainfall and erosion from spreading pollutants. In a second cleanup phase, an 18-inch
clay layer was placed on the site. The entire area was fenced and posted. The cap was seeded in
1986.
Entire Site: In 1990, the EPA selected a remedy for cleanup of the site, which
includes excavation, on-site chemical dechlorination, and on-site disposal of
contaminated soils. Engineering designs for the cleanup activities began in 1991.
Information discovered during the design, however, indicated these remedies would not be
feasible. In 1993, the EPA amended the remedy to call for capping the 9,800 cubic yards of
contaminated soil in place. Construction of the cap began in late 1994 and is expected to be
completed in 1996.
Site Facts: In 1985, the EPA issued an Administrative Order to the potentially responsible
parties to decontaminate and remove junked cars, remove and properly dispose of electrical
equipment and drums containing hazardous substances, install a fence, and build a synthetic liner
and clay cap to prevent runoff from spreading contaminants.
Environmental Progress
The EPA has completed many cleanup activities at the Tenth Street Dump/Junkyard site,
including decontamination of hazardous items and fencing the site, making the site safer as the
site cap is being built.

waste pits, three radioactive disposal sites, Building 3001, the two adjacent underground storage
tank areas, adjacent Soldier Creek, and the contaminated groundwater under the base. Tinker Air
Force Base (AFB) was activated in 1942. Its primary mission was to serve as a worldwide repair
depot for aircraft and associated equipment and weaponry. The Building 3001 complex uses large
quantities of industrial solvents in its business of maintaining aircraft and rebuilding jet engines.
In the past, waste oils, solvents, paint sludges, and plating waste generated from maintenance
activities were disposed of in two industrial waste pits, 1 mile south of Soldier Creek and
Building 3001. Since 1979, industrial wastes have been disposed of off site. The base is located
in the recharge zone of the Garber-Wellington Aquifer. Four landfills and the groundwater are
contaminated with chromium and trichloroethylene (TCE). As of 1988, four drinking water wells
at the base were polluted. The closest municipal well, 1/2 mile to the northwest, serves
approximately 55,400 people. The nearest residences and drinking wells are 300 feet from the

August 1 995
-------
Cleanup Approach
This site is being addressed in three stages: emergency actions and two long-term remedial
phases focusing on cleanup of contaminants at the Building 3001 Complex and Soldier Creek.
Response Action Status
Emergency Actions: In 1985, the Air Force removed tanks in Building 3001,
contaminated soil from on-base streams, and contaminants from the groundwater
under one of the site's facility. In addition, a cap was installed at one of the landfills,
with additional capping on its Southeastern corner. Two wells were plugged in 1986. In mid-
1988, floating free product was removed from the groundwater under the POL Facility. In 1990,
contaminated liquids were removed from the waste pit. The pit has since been cleaned,
backfilled, and capped. Tinker has provided bottled water to those residents with contaminated
drinking water wells. Midwest City is currently supplying affected residents with city water
hookups.
Building 3001 Complex: In 1987, the Air Force contracted with the U.S. Army
Corps of Engineers to do an 18-month study that is the equivalent of the Superfund
investigation into site contaminants and remedies. In 1990, a remedy was selected for
the site including the extraction of contaminated groundwater and treatment by air or steam
stripping, metals precipitation, and fine filtration; and the extraction and destruction of floating
petroleum from the North Tank Area using soil vapor extraction and thermal destruction
technologies. In addition, the liquids will be removed from Pit No. Q-51 and disposed of off site
and the pit will be cleaned. The removal of fuel products above the water table began in mid-
1991. Construction of the groundwater treatment plant was completed in 1993 and the plant is
operating as designed. The plant will continue to teat contaminated groundwater until established
cleanup levels are met.
Soldier Creek: Investigations into the nature and extent of the contaminants at
Soldier Creek were completed in 1993. Based on the results of these investigations,
the EPA determined that Soldier Creek poses no threat to human health, and therefore
requires no cleanup at this time. An ecological risk assessment began in 1994 to determine if
Soldier Creek poses a serious threat to the surrounding environment.
Site Facts: Tinker AFB is participating in the Installation Restoration Program, a specially
funded program established by the Department of Defense (DOD) hi 1978 to identify, investigate,
and control the migration of hazardous contaminants at military and other DOD facilities. A
federal facility agreement was signed between the Air Force and EPA in late 1989.
