INTRODUCTION
A BRIEF OVERVIEW OF SUPERFUND
D urine the second half of the Twentieth
Century, the environmental conse-
quences of more than 100 years of industrial-
ization m the United States became increas-
ingly clear. Authors such as Rachel Carson
wrote passionately about the often-hidden en-
vironmental effects of our modern society's
widespread use of chemicals and other haz-
ardous materials. Their audience was small at
first, but gradually their message spread.
Growing concern turned to action, as people
learned more about the environment and be-
gan to act on their knowledge
The 1970s saw environmental issues burst
onto the national scene and take hold in the
national consciousness. The first Earth Day
was observed in 1970, the year that the U.S.
Environmental Protection Agency (EPA) was
founded. By the end of the 1970s, Love Canal
in New York and the Valley of the Drums in
Kentucky had entered the popular lexicon as
synonyms for pollution and environmental
degradation.
Superfund Is Established
The industrialization that gave Americans the
world's highest standard of living also created
problems that only a national program could
address. By 1980. the U.S. Congress had
passed numerous environmental laws, imple-
mented by the EPA, but many serious hazard-
ous waste problems were slipping through the
cracks.
Responding to growing concern about public-
health and environmental threats from uncon-
trolled releases of hazardous materials, the
U.S. Congress passed the Comprehensive En-
vironmental Response. Compensation, and
Liability Act (CERCLA). Popularly known as
Superfund. CERCLA had one seemingly
simple job—to uncover and clean up hazard-
ous materials spills and contaminated sites.
A Big Job
Few in Congress, the EPA. the environmen-
tal community, or the general public knew in
19X0 just how big the nation's hazardous ma-
terials problem is. Almost everyone thought
that Superfund would be a short-lived pro-
gram requiring relatively few resources to
clean up at most a few hundred sites. They
were quite mistaken.
As the EPA set to work finding sites and
gauging their potential to harm people and
the environment, the number of sites grew.
Each discovery seemed to lead to another.
and today almost 36,000 hazardous waste
sites have been investigated as potential haz-
ardous waste sites. They are catalogued in
the EPA's computerized database, CERCLIS
(for the Comprehensive Environmental Re-
-------
INTRODUCTION
sponse, Compensation, and Liability
Information System).
The damage to public health and the
environment that each site in
CERCLIS might cause is evaluated;
many sites have been referred to
State and local governments for
cleanup. The EPA lists the
nation's most serious hazardous
waste sites on the National
Priorities List, or NPL. (These
Superfund sites are eligible for
federally-funded cleanup, but
whenever possible the EPA makes
polluters pay for the contamination
they helped create.) The NPL now
numbers 1,275 sites, with 50 to 100
added each year. By the end of the
century, the NPL may reach as many
as 2000 sites.
Superfund faces some of the most
complex pollution problems ever
encountered by an environmental
program. Improperly stored or
disposed chemicals and the soil
they contaminate are one concern.
More difficult to correct are the
wetlands and bays, and the
groundwater, lakes, and rivers
often used for drinking water that
are contaminated by chemicals
spreading through the soil or
mixing with storm water runoff.
Toxic vapors contaminate the air at
some sites, threatening the health
of people living and working near
by.
Superfund aims to control immediate
public health and environmental
threats by tackling the worst
problems at the worst sites first.
Wherever possible, Superfund
officials use innovative treatment
techniques many developed or
refined by the EPA to correct
hazardous materials problems once
and for all. Many of the treatment
techniques they use did not exist
when the program was created.
The EPA Administrator had
challenged Superfund to complete
construction necessary for cleanup
work at 200 NPL sites by the end of
the 1992 federal fiscal year. By
September 30, 1992, the end of
fiscal year 1992, construction had
been completed at a total of 149
NPL sites. By September 30, 1993,
the end of fiscal year 1993,
construction had been completed at
217 sites, well in excess of the
Administrator's target of 200. The
Superfund program now projects
completing construction at over 650
sites by the year 2000.
Quick Cleanup at NON-NPL Sites
Long-standing hazardous waste sites
are not Superfund's only concern.
The EPA also responds to hazardous
spillsand other emergencies,
hauling away chemicals for proper
treatment or disposal. Superfund
teams perform"or supervise
responses at rail and motor vehicle
accidents, fires, and other
emergencies involving hazardous
substances. They also evacuate
people living and working near by,
if necessary, and provide clean
drinking water to people whose own
water is contaminated. Removal
crews also post warning signs and
take other precautions to keep
people and animals away from
hazardous substances.
Quick Cleanups, or Removals are not
limited to emergencies. When
cleanup crews at contaminated sites
find hazardous substances that
immediately threaten people or the
environment, they act right away to
reduce the threat or to remove the
chemicals outright. As the EPA
implements the Superfund
Accelerated Cleanup Model (SACM),
more and more sites will undergo
quick cleanups, and many of these
will be cleaned up completely •
-------
INTRODUCTION
withouc ever being included on the
NPL. (See "Streamlining Superfund
Accelerated Cleanup Model.")
Some of Superfund's most
significant gains in public health
and environmental protection have
been won by the removal program.
As of October 1, 1993, the
Emergency Response Program in
Region V has lost approximately 500
removal completions since Superfund
was established.
Public Participation
Superfund is unique among federal
programs in its commitment to
citizen participation. Although
the EPA is responsible for
determining how dangerous a site is
and how best to clean it up, the
Agency relies on citizen input as
it makes these decisions.
Probably, the most important
component of any NPL site is public
participation. Community
Involvement has played a
significant role in the development
of cleanup activities at a site.
Although most proposals for cleanup
activities are brought forth by the
agency, it is usually the citizen's
input that gives the "stamp of
approval" on the cleanup plan.
Residents also comment on EPA
cleanup plans by stating their
concerns and preferences at public
meetings and other forums and in
formal written comments to Agency
proposals. The EPA takes and
concerns seriously, and has
modified many proposals in response
to local concerns. For ultimately,
it is the community and its
citizens that will live with the
results of the EPA's decisions and
actions; it is only fair that
citizens participate in the
process.
A Commitment to Communication
The Superfund program is very
serious about public outreach and
communication. Community relations
coordinators are assigned to each
NPL site to help the public
understand the potential hazards
present, as well as, the cleanup
alternatives. Local information
repositories, such as libraries or
other public buildings, have been
established near each NPL site to
ensure that the public has an
opportunity to review all relevant
information and the proposed
cleanup plans. The individual
State volumes contain summary fact
sheets on NPL sites in each State
and territory. Together, the fact
sheets provide a concise report on
site conditions and the progress
made toward site cleanups as of May
1994. The EPA revises these
volumes periodically to provide and
up-to-date record of program
activities. A glossary of terms
relating to hazardous waste
management and Superfund site
cleanup is provided at the back of
this book.
Superfund is, of course, a public
program, and as such it belongs to
everyone of us.
-------
INTRODUCTION
STREAMLINING SUPERFUND: THE SUPERFUND
ACCELERATED CLEANUP MODEL
Historically, critics and
supporters alike have measured
Superfund's progress by the number
of hazardous waste sites deleted
from the NPL. Although easy enough
to tally, this approach does not
recognize the breadth of risk
reduction attained by Superfund.
First, it doesn't account for the
early remedial actions conducted at
the nations worst hazardous waste
sites, which occurs well before
site deletion. Second, it ignores
the significant contribution to
reducing risks to human health and
the environment by the Removal
Program.
In renewing Superfund's commitment
to quick and early response
actions, EPA has undertaken an
initiative to streamline the
Superfund program. The Superfund
Accelerated Cleanup Model (SACM)
emphasizes the conduct of early
actions, such as drum removal and
source control, while long-term
actions, such as groundwater
contamination are appropriately
studied. In addition, SACM
envisions an integrated site
assessment process whereby the
different Superfund assessments are
integrated into a single process.
Integrated assessments will reduce
the time and resources required to
evaluate a site and assess its
threats to human health and the
environment. This way, immediate
public health and environmental
threats will be addressed while
long-term cleanups are being
planned.
Emergencies such as train
derailments and motor vehicle
accidents will continue to be
handled expeditiously. Teams of
highly trained technicians will
swing into action right away,
coordinating the cleanup and
removal of hazardous substances to
ensure public safety as quickly as
possible.
BREAKING WITH TRADITION
The traditional Superfund process
begins with a lengthy phase of
study and site assessment, but SACM
will save time by combing separate,
yet similar, activities.
Each EPA Region will form a
Regional Decision Team (RDT)
composed of program managers from
the Removal and Remedial program,
the Office of Regional Counsel,
Office of Public Affairs,
Environmental Science Division, and
the States. The RDT will be
responsible for making decisions on
sites based on recommendations by
Site Assessment Teams (SATs). The
SATs are comprised of an RPM, OSC,
SAM, staff attorney, State
representative, and community
relations coordinator. Other
experts such as ecologist and
toxicologists are brought in on the
SATs on an as needed basis. SATs
develop site specific strategies
potentially utilizing Removal (i.e.
early action) and/or Remedial (i.e.
long-term action) statutory
authorities.
In many instances, SATs will
recommend to the RDT the initiation
of a -study for a long-term action
while work begins on an early
action to eliminate an immediate
threat to public health and the
environment.
Early Actions include taking
precautions to keep contaminants
from moving off the site and
restricting access to the site.
Early Actions can eliminate most,
if not all, risk associated with a
Superfund site. Consequently,
early public involvement is
-------
INTRODUCTION
BREAKING WITH TRADITION
cont'
participation during the site
assessment process and Early
Actions.
LONG-TERM SOLUTIONS
While Early Actions can correct
many hazardous waste problems and
provide the bulk of public health
and environmental protection some
contamination will take longer to
correct. Cleanups of mining sites,
wetlands, estuaries, and projects
involving incineration of
contaminants or restoration of
ground water can take far longer
than the three to five years
envisioned for Early Actions.
Under the SACM paradigm, the
conduct of the long-term cleanup
action will be similar to the
present process.
Also under SACM, the EPA will
continue its pursuit of potentially
responsible parties who may have
caused or contributed to site
contamination. Expedited
enforcement and procedures for
negotiating potentially responsible
party settlements will secure their
participation. Superfund personnel
will continue to oversee clean-up
work performed by potentially
responsible parties.
-------
INTRODUCTION
HOW SUPERFUND WORKS
Each Superfund site presents a different
set of complex problems. The same haz-
ardous materials and chemicals often con-
taminate many sites, but the details of each
site are different Almost always, soil is con-
taminated with one or more chemicals. Their
vapors may taint the air over and around the
site. Contaminants may travel through the soil
and reach underground aquifers which may be
used for drinking water, or they may spread
over the site to contaminate streams, ponds,
and wetlands. The contaminating chemicals
may interact with each other, presenting even
more complicated cleanup problems.
Superfund's cleanup process is arduous and
exacting. It requires the best efforts of hun-
dreds of experts in science and engineering,
public health, administration and manage-
ment, law, and many other fields.
The average NPL site takes from seven to ten
years to work its way through the system,
from discovery to the start of long-term
cleanup. Actual cleanup work can take years,
decades if contaminated groundwater must
be treated. Of course, imminent threats to
public health or the environment are cor-
rected right away.
The diagram to the right presents a simplified
view of the cleanup process. The major steps
in the Superfund process are:
• Site discovery and investigation to iden-
tify contaminants and determine whether
emergency action is required;
• Emergency site work such as removing
contaminants for proper treatment or dis-
posal, and securing the site to keep people
and animals away, if warranted by condi-
tions at the site;
• Site evaluation to determine how people
living and working nearby, and the envi-
ronment, may be exposed to site contami-
nants;
Detailed studies to determine whether con-
ditions are serious enough to add the site to
the National Priorities List of sites eligible
for federally funded cleanup under Super-
fund;
Selection, design, and implementation of a
cleanup plan, after a thorough review of
the most effective cleanup options, given
site conditions, contaminants present, and
their potential threat to public health or the
environment
• Follow-up to ensure that the cleanup work
done at the site continues to be effective
over the long term.
The Superfund Process
From the earliest stages, EPA investigators
work hard to identify those responsible for the
contamination. As their responsibility is es-
tablished, the EPA negotiates with these "re-
sponsible parties" to pay for cleaning up the
problem they helped create. This "enforce-
ment first" policy saves-Superfund Trust Fund
monies for use in cleanups where the respon-
sible parties cannot be identified, or where
they are unable to fund cleanup work.

THE VOLUME
How to Use the State Book
The sue fact sheets presented in this book
ore 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 tact
sheets conclude with a brier 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 always is being
made at NPL .sites, and the EPA periodically ~
will update the site fact sheets to reflect recent
actions and will publish updated State vol-
umes. The following two pages show a ge-
neric fact sheet and briefly describe the infor-
mation under each section.
How Can You Use
This State Book?
You can use this book to keep informed about
the sites that concern you. particularly ones
close to home. The EPA is committed 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 Super-
fund sites. Citizens are likely to be affected
not only by hazardous site conditions, but also
by the remedies that combat them. Site clean-
ups take many forms and can affect communi-
ties in different ways. Local traffic may be
rerouted, residents may be relocated, tempo-
rary 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.

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

A SUMMARY OF THE STATE PROGRAM
-------
SUPERFUND ACTIVITIES IN OHIO
The State of Ohio is located within EPA Region 5, which includes the six
midwestern States. The State covers 41,330 square miles. According to the
1990 Census, Ohio experienced a slight increase in population between 1980
and 1990, and is ranked seventh in US.S population with
approximately 10,847,000 residents.
The Ohio Solid and Hazardous Waste Disposal Law, enacted in
1980 and amended in 1988, establishes funding and enforcement
authorities for site cleanup. The statute grants the State the
authority to comply polluters to conduct or pay for site
cleanup, demand site access, issue civil and criminal
penalties, recover the cost of State actions, allow citizen
suits, and place alien on property as a means of payment. In practice the
State must attempt to reach an agreement with the polluter before taking
action: the State is prohibited from taking action where the EPA is
pursuing a claim. The State maintains tow funds which include the
Hazardous Waste Cleanup Fund and the Hazardous Waste Facility Management
Fund. The Hazardous Waste Cleanup Fund is used to fund day-to day
activities, build additional hazardous waste facilities, and to purchase
sites. The Hazardous Waste Facility Management Fund provide the required
10 percent State contribution to the Federal Superfund program as well as
funds for State level-of-effort contracts and non-investigatory emergency
response actions. Currently, 34 sites in the State of Ohio have been
listed as final on the NPL.

Ironton
Site Description
The 95-acre Allied Chemical & Ironton Coke site is bordered by the Ohio River and Ice
Creek. It includes two industrial facilities that formerly used on-site lagoons to hold
hazardous wastes. There are four major areas of concern on this site: the coke plant, the
coke plant lagoons, the tar plant, and the Goldcamp disposal area. Manufacturing operations
at the coke plant began in 1917. From 1920 to the late 1960s, wastewater and solid wastes
generated in the coking process were discharged into the area east of the plant, which
drained toward Ice Creek. In the early 1970s, a series of lagoons were constructed on site for
treatment of plant process wastewater. The lagoons were constructed by building dikes with
site materials, including soil and solid wastes. In 1982, the coke plant, including the lagoon
system, was shut down. In 1945, the tar plant was constructed across from the coke plant.
The purpose of the tar plant was to manufacture products from the tar produced in the
coking process. The tar plant currently is operating. Some of the process wastes for the tar
plant were disposed of in an adjacent sand and gravel pit called the Goldcamp disposal site,
which has been owned by the Allied Chemical and Dye Company since 1955. In the late
1970s, the Goldcamp Disposal site was closed by removing standing water, filling, and capping
with imported clay soil. Underlying the Goldcamp Disposal Area (GDA), contaminants have
migrated downward through the aquifer to the surface of the underlying impermeable
bedrock. The surface of the GDA also is a source of contamination, because many
substances have oozed up through the existing cap. Approximately 14,000 people live in
Ironton. Groundwater is the main source of municipal water for the city. The Ohio River and
Ice Creek are used for recreational activities including fishing.
Site Responsibility: This site is being addressed through
Federal and potentially responsible
parties' actions.

Threats and Contaminants
The groundwater, soil, and sediments are contaminated with volatile organic
compounds (VOCs), phenols, polycyclic aromatic hydrocarbons (PAHs), inorganics
including cyanide, and the heavy metal arsenic. Potential health threats include
direct contact or accidental ingestion of these contaminants in the soil, sediments,
or groundwater, which is used as a source of drinking water in the Village of Coal
Grove, approximately 2,000 feet from the site.
Cleanup Approach
This site is being addressed in three stages: an initial action and two long-term remedial
phases focusing on cleanup of the Goldcamp Disposal Area and cleanup of the Coke
Plant/Lagoon area.
Response Action Status
Initial Action: The parties potentially responsible for site contamination have
dismantled the coke plant located on the site in preparation for the site cleanup.
Cleanup of the coke plant area will be completed under another phase as
Goldcamp Disposal Area: Based on the results of the Goldcamp Disposal
Area investigation, the EPA selected the following cleanup actions:
construction of a slurry wall around the disposal area; installation of a cover over
the surface of the disposal area; extraction and on-site treatment of groundwater from inside
and outside the containment system; provision of an alternate water supply for the Ironton
Iron Company until groundwater cleanup levels are met; imposition of deed restrictions to
limit future uses of the property; and preparation of a supplemental pre-design investigation.
The pre-design investigation was completed in 1991, and the subsequent design was
completed in 1993. Construction of the site remedy has begun and construction completion
and startup of the groundwater pump and treatment system is scheduled to be completed by
November 1994.
Coke Plant/Lagoon Area: Based on the results of the Coke Plant/Lagoon Area
investigation, the EPA selected the following cleanup actions: on-site incineration
of approximately 122,000 cubic yards of lagoon waste materials with the heat being
produced by the incinerator being used by the operating tar plant near the site; in-place
bioremediation of approximately 457,000 cubic yards of lagoon waste material; bioremediation
of approximately 40,000 cubic yards of soil on a prepared surface; and pumping and on-site
treatment of groundwater. In addition, groundwater will be monitored downgradient of Ice
Creek; a contingency plan will be prepared; fencing, security, and deed restrictions will be put
in place. The waste material from the lagoons has been further defined and approximately
175,000 cubic yards is being incinerated; in-place bioremediation of 377,000 cubic yards of
lagoon waste, and removal of 13,000 cubic yards of lagoon material and 38,000 cubic yards of

contaminated soil to be treated by two bioremediation methods on a prepared surface. The
parties potentially responsible for site contamination, under EPA monitoring, began designing
the technologies to be used in the cleanup in 1991. The bioremediation is scheduled to begin
in Spring 1995. The design for the incinerator will be completed in 1996 and construction will
commence in late 1996.
Site Facts: The EPA issued a Unilateral Administrative Order in 1989 for partial cleanup of
the site. The order calls for Allied-Chemical, Inc. and the AMCAST Industrial Corporation to
design and conduct cleanup of the Goldcamp Disposal Area on the site.
Environmental Progress
The dismantling of the coke plant and continuous site security, along with the earlier actions
taken to close the disposal area, have reduced the potential for exposure to hazardous
substances at the Allied Chemical & Ironton Coke site while further cleanup activities are
being planned.

Tuscarawas County
Gnadenhutten
Site Description
The 4 3/4-acre Alsco Anaconda site is owned by the ARCO Chemical Company, a division of
Atlantic Richfield. From 1965 to 1978, the site was used for the disposal of wastewater and
wastewater treatment sludge that were generated by the production of aluminum products.
The sludge was disposed of in two unlined lagoons and a sludge pit. From 1971 to 1978, the
company disposed of the equivalent of approximately 18,000 drums of waste. The lagoons and
sludge pit contained contaminants including chromium and cyanide. A wooded low-lying area
near the river received overflow from the lagoons. The remaining wastewater was discharged
into the Tuscarawas River. Since 1978, sludge has been disposed of at an off-site facility.
However, over 4,800 tons of sludge were disposed on the property, spread across most of the
site. Approximately 3,100 people live within 3 miles of the site. These individuals depend on
city and private drinking water wells drawn from groundwater aquifers, as there are no
alternative sources of drinking water. Contaminated groundwater from the site generally
flows toward the Tuscarawas River, and away from the city water supply wells. The site is
located within both the 50 and 100-year flood plains of the Tuscarawas River, which is used
for various recreational activities.
Site Responsibility:
This site is being addressed through
Federal, State, and potentially
responsible parties' actions.

Threats and Contaminants
The groundwater, is contaminated with such constituents as cyanide, chromium and
other metals. The soil on-site did contain such contaminants as cyanide, chromium
and polychlorinated biphenyls (PCBs). However, most contaminated soil has been
removed. Possible health threats include accidentally ingesting or coming in direct
contact with contaminated groundwater or soil. If a flood of the Tuscarawas River
should occur, some of the remaining contaminants could be washed into the river.

Cleanup Approach
This site is being addressed in two long-term remedial phases focusing on cleanup of the
sludge and soil and cleanup of the groundwater and surface water.
Response Action Status
Sludge and Soil: In 1989, based on the results of the site investigation, the EPA
selected the following methods for cleanup of contaminated sludge and soil: highly
contaminated sludge from the wooded area was to be excavated and hauled to a
facility for incineration (this was approximately 15 cubic yards of material); the remaining
wastes from the wooded area, the lagoons, and the sludge pit were to be excavated and
treated prior to disposal, as necessary, and hauled to a licensed landfill and the excavated
lagoons and sludge pit were to be filled with clean back fill. The excavation of the sludge and
soil began in the spring of 1992. A much larger volume of waste was discovered than was
expected. This additional waste included buried drums, soil contaminated with organic
constituents, an waste extending outside the property boundaries. Additional investigations
and studies have been conducted, and cleanup is planned for completion by late 1994.
Groundwater and Surface Water: The parties potentially responsible for site
contamination have conducted a supplemental study to determine the nature and
extent of groundwater and surface water contamination. The final study and risk
assessment were completed in 1992. Remedial design is underway.
Site Facts: A 1987 agreement between the EPA, the Ohio EPA, and ARCO provided for a
site investigation to be completed by the company, under EPA monitoring. In 1989, the EPA
issued Unilateral Administrative Orders to both Harvard Industries and ARCO to clean up
the source materials found on site. In 1993, EPA issused a Unilateral Administrative Order
to ARCO for the remedial design/remedial action for the groundwater operable unit.
Environmental Progress
After adding this site to the NPL, the EPA performed preliminary investigations and
determined that no immediate actions were required at the Alsco Anaconda site while further
studies were taking place and final cleanup activities are underway.

Arcanum
Site Description
The 4 1/2-acre Arcanum Iron and Metal (AIM) site operated as a lead battery reprocessing
facility from the early 1960s until 1982. During this operation, battery casings were split to
extract lead cores for smelting. Battery acids generated from this operation were dumped in a
large steel trough and allowed to drain to a low area. Reprocessing of the plastic and black
rubber battery casings generated lead oxide sludge that collected on the ground and surface
ponds on site. Past practices at the facility included burial of some materials in on-site pits.
The State of Ohio investigated a fish kill in Sycamore Ditch and Painter Creek near the site
in 1964. Testing of groundwater was not performed until the 1970s. The City of Arcanum's
water supply is furnished by wells within 1 mile of the site, and private wells also are nearby.

Threats and Contaminants
Groundwater on the site contains lead. Lead, antimony, and arsenic have been
detected in the sediments and soil. Potential risks may exist for individuals
ingesting or coming in direct contact with contaminated groundwater or soils.
Cleanup Approach
This site is being addressed in two stages: an immediate action and a long-term remedial
phase focusing on cleanup of the entire site.
May 1994
-------
Response Action Status
Immediate Action: To reduce public access to the contaminated site areas, the
parties potentially responsible for the contamination constructed a fence around
the entire site in 1984.
Entire Site: In 1986, the EPA determined the following actions would be
necessary to clean up the site: excavation of on-site contaminated soils and
battery casings with off-site disposal in a federally approved landfill; excavation
and disposal of off-site soils exceeding human health standards in a federally approved
facility; improvement of site drainage; demolition or cleaning of contaminated on-site
facilities; implementation of deed restrictions for land and aquifer use; continuance of semi-
annual groundwater monitoring; and conducting site treatability studies. The EPA intends to
combine cleanup of the site with the United Scrap Lead site, another NPL site located
approximately 30 miles away that is similarly contaminated. Contaminated soils will be
removed to the United Scrap Lead site for treatment and returned to the AIM site.
Revisions to the initially proposed cleanup actions include placing a soil cover over the
excavated areas and recovery of lead from contaminated soil. A study began in 1987 to
address the appropriateness of potential contaminant recovery and cleanup methods as part
of the remedy design. The design is scheduled to be completed in 1993.
Site Facts: In 1979, the State entered into a Consent Decree with the owner to clean up
the site, but the results were unsatisfactory. The owner ceased operation in 1982, having
never fully complied with the provisions of the State Consent Decree.
Environmental Progress
Fencing of the entire site has reduced the potential for exposure to contaminated materials at
the Arcanum Iron & Metal site while further studies are taking place and cleanup activities
are being designed.

Ashtabula County
1 112 miles northeast of Kingsville
Township
The 7 1/2-acre Big D Campground site consists of a former sand and gravel quarry that was
used between 1964 and 1976 for the disposal of a variety of industrial wastes. The Olin
Chemical Corporation estimates that 25,000 to 30,000 cubic yards of industrial bulk wastes,
drums, and soil were disposed of at the site. Olin investigated possible contamination
problems at the site in 1978. As part of the investigation, Olin installed three groundwater
monitoring wells on the north side of Conneaut Creek and collected water samples from the
wells. The results of these sampling efforts indicated the presence of volatile organic,
compounds (VOCs) in the groundwater. In 1982, Olin reported the findings of its
investigation to the EPA. Subsequent groundwater sampling conducted by the EPA in 1982
confirmed the presence of VOCs in the groundwater. Approximately 3,900 people live within
a 3-mile radius of the site. The distance from the site to the nearest residence is
approximately 500 feet.

Threats and Contaminants
Groundwater and soil are contaminated with VOCs and heavy metals including
barium, chromium, lead, and nickel. At present, area residents are not exposed to
site-related contaminants located in the on-site groundwater. All residents receive
drinking water from the municipal water supply system, and private wells located
near the site are not contaminated and have been closed. In addition, potential
exposure to contaminated soil is limited by the soil and vegetation covering the
landfilled area. However, the EPA is concerned about the potential for future
exposure. Existing private wells could become contaminated if the area of
groundwater contamination believed to have originated from the site migrates
farther northward.
May 1994
-------
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: When erosion of the landfill soil cover exposed buried drums in
1983, Olin covered the surface of the landfill area with clay and took steps to
control any further erosion of soil from the base of the slope. In addition, Olin
installed a rainwater collection trench to remove rainfall runoff from the covered area and
drilled 11 new groundwater monitoring wells on the site to expand its groundwater monitoring
program.
Entire Site: As a result of the investigation completed by the EPA in 1989, the
remedy selected to address site contamination includes the following activities:
excavating drums and contaminated soils; burning excavated materials in an
incinerator; filling the excavated area with soil and planting vegetation; constructing a fence
around the excavated area and incinerator; installing a groundwater recharge trench and 8
groundwater extractions wells near the site to withdraw contaminated groundwater; treating
contaminated groundwater by passing it through air stripping and a carbon filter system to
remove contaminants and discharge of treated water to Conneaut Creek; deed restrictions on
future site uses; and monitoring groundwater and surface water quality to assess the
effectiveness of the cleanup. The parties potentially responsible for site contamination began
developing a work plan to design the final remedies in 1990.
Site Facts: In September 1992, the on-site incinerator began operations. Over 14,500 drums
were excavated from the landfill and burned in the incinerator. Over 95,000 tons of
contaminated material has been burned. The groundwater extraction system is scheduled to
be installed in the Spring 1994.
Environmental Progress
The steps taken to control further erosion of contaminated soil from the Big D Campground
site have reduced the potential of exposure to contaminants while activities leading to the
final site cleanup are being completed.

Site Description
The 12-acre Bowers Landfill site operated as a pit for gravel excavation operations beginning
in 1958, but its owners subsequently converted it to a landfill, which at first accepted only
domestic refuse. From 1958 to 1968, it accepted residential, grain elevator, and industrial
wastes. Two local manufacturers of chemicals responded to a Congressional inquiry about the
site and noted that they dumped approximately 7,500 tons of chemical waste at the landfill.
Disposal practices frequently consisted of depositing the waste directly onto the ground and
covering it with soil. Waste also was burned on site. Operations at the landfill ended in about
1968. In 1980, the EPA found that contaminants in the landfill were polluting nearby
monitoring wells with volatile organic compounds (VOCs). Approximately 60 people live
within 1/2 mile of the site.

Threats and Contaminants
Groundwater on site contains heavy metals including barium and manganese,
VOCs, and phthalates. Sediments are contaminated with polychlorinated biphenyls
(PCBs), petrochemicals, pesticides, VOCs, and lead. Contaminants in the soil
include petrochemicals, lead, and PCBs. Off-site soils contain heavy metals
including arsenic, as well as pesticides. Surface water is contaminated with VOCs,
polycyclic aromatic hydrocarbons (PAHs), and heavy metals. Potential health risks
exist for individuals who drink or come in direct contact with contaminated
groundwater, inhale contaminated soil or sediment particles, or eat small animals,
birds, fish or plants that are contaminated with chemicals from the site. The area
between the landfill and the Scioto River generally floods twice a year, which
further contributes to the threat of contaminant releases.
May 1994
-------
Cleanup Approach
This site is being addressed in a long-term remedial phase focusing on cleanup of the entire
site.
Response Action Status
Entire Site: The EPA studied the nature and extent of contamination at the site
from 1983 to 1989. The results of this study, along with a study by the parties
potentially responsible for the site contamination, were used to prepare an analysis
of the alternatives for addressing the threat the landfill poses to people and the environment.
In 1989, the EPA recommended the following actions at the site to address the
contamination problem: removing and disposing of all surface debris in an approved landfill;
improving erosion control and drainage; installing a natural clay cover over the landfill;
installing a topsoil layer over the clay cover; protecting the cap from flood damage; installing
a limited number of new groundwater monitoring wells; taking samples of the groundwater
and analyzing them to determine any increases in the level of contaminants; and installing a
fence to prevent site entry. Cleanup work began in 1991, and completed in 1993.
The Site is now in Operation and Maintenance to ensure the remedy is effective.
Environmental Progress
After adding this site to the NPL, the EPA performed preliminary investigations and the
remedy has been completed. A new wetlands was developed as part of the RA.

-------
Response Action Status
Entire Site: The parties potentially responsible for the contamination initiated an
investigation in 1985 to determine the type and extent of contamination at the
site and to identify alternative remedies for the cleanup. The investigation,
completed in 1991, resulted in the selection of the following remedies: capping the waste and
surface area recharge areas, constructing a surface leachate and groundwater collection
system, and treating leachate in the groundwater via constructed wetlands. Deed restrictions
will be implemented on the future use of the site and the property will be fenced. Ground
water will be monitored. The companies have begun designing the selected remedies. Actual
cleanup activities are expected to begin in 1995.
Site Facts: An agreement between the EPA, the State of Ohio, and six companies was
reached in 1985, requiring the companies to investigate possible contamination at and around
the landfill. In 1992, an agreement between EPA and 14 companies was reached, requiring
the companies to design the remedy. The companies will carry out the project under EPA

The Chemical Mineral Reclamation, Inc. site (CMR) covers a 3/4 acre area located on the
north side of Cleveland, Ohio on the floodplain of the Cuyahoga River. The site is located in
a metropolitan area surrounded by the Cleveland Memorial Shoreway to the south and west,
the old Cuyahoga River bed to the north, and industrial property to the east. The owner of
the area, Plain Dealer, leased this land to CMR in 1979. CMR planned to use the site as a
recycling facility, but in the end only collected and stored wastes in vats and barrels. The vats
and barrels contained miscellaneous wastes including flammable and non-flammable solvents,
paints, tar, grease, and resins. These storage operations continued until July 2, 1980, when a
fire occurred at the warehouse on site. As a result of the fire, the Cleveland Memorial
Shoreway was closed temporarily, but no injuries were reported. On-site soil was suspected to
be contaminated by possible leaking and overflowing of the vats and barrels. The population
surrounding the site was the City of Cleveland with an estimated 573,822 people according to
the 1980 census. The entrance to the Cuyahoga River and Lake Erie is approximately 1 1/2
miles from the site. A boat docking area and several homes are nearby. A marina is located

non-chlorinated), paints, tar, grease, resins, and other miscellaneous wastes were
removed. Liquid and solid materials from six 3,500 gallon vats were also removed. Further
cleanup actions included compatibility testing of chemicals and the removal of chemicals to
various recyclers, incinerators, and landfills. The buildings on site were demolished and the
contaminated soil was removed to a licensed landfill. Site cleanup was completed in mid-
1982.
Site Facts: The Chemical Minerals Reclamation, Inc. site was placed on the Interim

The Diamond Shamrock Corp. (Painesville Works) site is a 500-acre property located
between Lake Erie and the Grand River. A large tire manufacturing facility is located to the
immediate east of the site, and an industrial area that is part of the city of Fairport Harbor
borders the site on the west. From 1912 until its close in 1972, the Diamond Shamrock Corp.
facility produced chemicals and accepted chemical wastes for disposal. In 1986, Maxus
Energy Corp. purchased the Diamond Shamrock Chemical Co. Shortly after, Maxus divided
the property into parcels and sold some of the parcels to Standard machine equipment.
Initially, the facility produced caustic soda, coke, chlorine, and chlorinated paraffins. Starting
in late 1931, the plant began to produce several additional compounds, such as sodium
dichromate, potassium dichromate, and chromic acid. The facility accepted spent pickle
liquor from nearby steel industries. These activities resulted in contamination in eight source
areas: contaminated soils in the main production area; 750 thousand tons of chromate waste
materials; three waste lakes; a water retention basin, a hazardous waste landfill; and
treatment lagoons for effluent from the production of chromate. During the demolition of
some on-site buildings, polychlorinated biphenyls (PCBs) were discovered in the transformer
oils. In 1981, the EPA conducted sampling of surface water and sediments at the site. The
EPA found heavy metals, such as mercury and hexavalent chromium, as well as cyanide, ethyl
benzene, xylene, and naphthalene. The site poses a threat to the drinking water intakes
along Lake Erie and to the fisheries, wetlands, and sensitive environments in the Grand River

The 10-acre Chem-Dyne site operated as an industrial chemical waste transfer, disposal, and
storage facility. As early as 1974, chemical wastes may have been trucked to the site. In 1975,
Spray-Dyne made antifreeze from recycled chemical wastes. The operation was expanded in
1976, and the Chem-Dyne Corporation was formed. Wastes that were unsuitable for recycling
were stored in drums and tanks on the site or shipped to other disposal sites. More than
30,000 drums of waste and 300,000 gallons of bulk waste materials were on site when
operations shut down in 1980. In the 5 years of operation, a number of environmental
incidents were reported at the site. From 1976 to 1979, at least five fish kills in the Great
Miami River were attributable to the Chem-Dyne facility; one fish kill stretched for 37 miles.
Fires occurred at the site in 1976 and 1979. A residential area is located approximately 1,000
feet from the site. A storm sewer drained the site into the Ford Canal, which flows into the
Great Miami River. The Ford Canal is used only for drainage and hydroelectric power

May 1994
-------
Cleanup Approach
This site is being addressed in two stages: immediate actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Immediate Actions: In 1980, the EPA stabilized, removed, and disposed of 17
potentially explosive drums at a federally approved treatment facility. Beginning in
1982, the EPA removed another 9,000 drums and solidified and removed 200,000
gallons of liquid and solid wastes in 33 storage tanks to a federally approved facility. Spilled
materials were cleaned up and wastewater was treated and disposed of. The storm drain in
the loading dock area was plugged to prevent the discharge of contaminated waste into Ford
Canal. The site also was fenced to prevent access.
Entire Site: In 1985, a remedy to clean up the site was selected by the EPA
which included installation of a system to extract the groundwater and treat it by
air stripping. The contaminants are further treated with activated carbon before
being released into the air. In addition, the buildings on the site were demolished, selected
areas of soil were removed, and a synthetic cap with a clay layer was placed over the site.
The parties potentially responsible for site contamination completed all surface cleanup
activities in 1987. The groundwater pump and treatment system has been in operation since
1988 and must operate until at least 1998 to meet established cleanup standards.
Site Facts: In 1979, the State of Ohio required all materials to be removed from the
Chem-Dyne site by 1980. In 1985, the EPA, Ohio EPA and 178 parties potentially responsible
for site contamination signed a Consent Decree requiring the parties to conduct cleanup
activities.

some of which later were replaced with chlorinated paraffin by-products. These by-products
are used in the manufacturing of pressure lubricants, flame retardants for vinyl products,
plasticizers, and phosphites, which are used as stabilizers in the plastics manufacturing
process. The plant refined chemicals contaminated with polychlorinated dibenzodioxins
(PCDDs) and polychlorinated bibenzofurans (PCDFs) in the 9-acre production area. In the
early 1960s, Dover Chemical disposed of 4,000 gallons of mixed chlorinated benzene
by-products in a swampy area in the southwest corner of the site. At about the same time,
Dover buried 10 drums of chlorinated paraffin by-products in the east central portion of the
site. In 1991, the EPA detected organics in on-site monitoring wells. About 27,000 people
use the municipal wells within 4 miles of the site. Eleven thousand of these people use the
water from the Dover municipal wells, one of which is located 1,100 feet from the site. The
remaining 16,000 people use water from the New Philadelphia municipal well field, which is
located about 4 miles from the site.

-------
SSicieanup 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 1981, Dover Chemical removed 975 tons of waste material
and surrounding contaminated soil. Dover Chemical took these materials to a
landfill approved and permitted under the Resource Conservation and Recovery
Act (RCRA) to accept waste. After this initial action, Dover Chemical conducted a site
study. Dover Chemical submitted the results in mid-1986 to the EPA and the Ohio
Environmental Protection Agency (OEPA). Both the EPA and the OEPA rejected the
report and requested that Dover Chemical collect more data and study the site in greater
depth. In 1991, Dover removed contaminated soils, transported them to a RCRA-regulated
facility for disposal, and stabilized the area. Late in 1992, Dover Chemical began to pump
contaminated groundwater to the surface and treat it to remove the contaminants.
Entire Site: A full-scale investigation into the remaining risks presented by the
site began in mid-1988. This investigation, which is being undertaken by the
potentially responsible parties, is scheduled for completion in late 1994. The
results of this investigation will guide the selection of remedies for final cleanup of site
contamination.
Site Facts: In late 1988, Dover Chemical entered into an Administrative Order on Consent
to complete an in-depth study of the nature and extent of contamination at the site. In June
1991, Dover Chemical agreed to an Administrative Order on Consent to remove and dispose
of contaminated soils and stabilize the area.
Environmental Progress
By removing contaminated waste material and soil, stabilizing the area, and initiating the
pumping and treatment of groundwater, the immediate threats posed by contaminants at the
site have been reduced. Once the full-scale site study is completed, remedies will be selected
for final cleanup of the site.

Site Description
EPA REGION 5
Lawrence County
4 1/2 miles northwest of Hanging Rock
The 3-acre E. H. Schilling Landfill site operated as an industrial waste landfill from 1969 until
1980. The landfill was licensed to accept only non-hazardous wastes, but was closed in 1980
as a result of permit violations. A variety of hazardous and non-hazardous wastes were
disposed of on site. Landfill waste is contained behind an earthen dam and beneath a cover
or cap. While the dam is structurally stable, it does not comply with existing safety standards.
The landfill cap also fails to comply with State and Federal regulations. Leachate was
discovered seeping from the face of the dam. Approximately 1,500 people live within 3 miles
of the site. The closest residence is located within 1/4 mile of the site. Domestic water is
taken from municipal and private wells. Wayne National Forest borders the site to the north.
An unnamed stream carries runoff from the site into Winkler Run and the Ohio River.
Site Responsibility: This site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY

Threats and Contaminants
Nickel has been detected in air sampled near the landfill at levels exceeding
Federal standards. Arsenic and volatile organic compounds (VOCs) have been
found in groundwater. Leachate, soil, and stream sediments are contaminated with
VOCs, polycyclic aromatic hydrocarbons (PAHs), and heavy metals. Individuals
who accidentally ingest contaminated groundwater, soil, or sediments may
potentially suffer adverse health effects.
Cleanup Approach
May 1994
-------
This site is being addressed in a long-term remedial phase focusing on cleanup of the entire
site.
Response Action Status
Entire Site: In 1989, the EPA selected the following cleanup technologies to
address site contamination: capping the entire site; removing and treating
7,000,000 gallons of liquid waste and leachate from the landfill by building an on-
site treatment plant. The treatment plant removes from the liquid waste and lechate metals,
VOC's, and semi-volatile organic compounds; constructing a cut-off wall around the landfill
to prevent groundwater from infiltrating into waste; improving the earthen dam by adding a
berm; consolidating 750 cubic yards of soil and 500 cubic yards of sediment under the cap;
adding perimeter drainage features; fencing the entire site; monitoring groundwater;
operating and maintaining the site; and imposing deed restrictions. The potentially responsible
parties, under EPA monitoring, completed the design for the selected remedies in 1992 and
immediately began cleanup operations. Construction was completed in August 1993 and the
treatment plant discharge has met all State of Ohio discharge requirements. It is estimated
that the system will take two to three years to remove the liquid waste and leachate from
within the landfill. Groundwater is monitored 4 times per year.
Environmental Progress
After adding this site to the NPL, the EPA performed preliminary investigations and
determined that no immediate actions were required at the E. H. Schilling Landfill site while
cleanup activities underway.

The 1,450-acre Feed Materials Production Center site was operated by the U.S. Department
of Energy (DOE) manufacturing metallic uranium for DOE nuclear weapon reactors from
1952-1989. The site is still owned by U.S. DOE but operated by FERMCO. Its mission has
changed from production to environmental cleanup. 1950s. The manufacturing processes have
generated large quantities of wastes, including low-level radioactive wastes, mixed hazardous
and radioactive wastes, oils, solvents, and fly ash. Operations and disposal practices have
resulted in contamination in the production area, six waste pits, three waste storage silos, a
storm sewer ditch leading to Paddy's Run, and an effluent line discharging into the Great
Miami River. Additional waste storage and disposal areas included other silos, a burn pit, a
clear well, two fly ash disposal areas, a sanitary landfill, and two lime sludge ponds. Uranium
has contaminated the Buried Valley Aquifer, the sole source of drinking water for the
production center workers and most area residents. A residential area is located about 4,000
feet east of the production area. The Great Miami River is used for various recreational
purposes.

Cleanup Approach
Cleanup activities at this site are being addressed in six parts: (29) immediate actions and five
long-term remedial phases (operable units) focusing on cleanup of the waste pits, soils and
groundwater, the production area, the K-65 silos, and other source areas. U.S DOE is also
partially funding an alternate water supply and system for the public.
Response Action Status
Immediate Actions: There have been 29 immediate action that have either
been completed or on-going at the site.
Waste Pits: The DOE has completed investigating the nature and the extent of
the contamination in the waste pits and surrounding soils. The pits contain over
600,000 cubic yards of wastes, and approximately 500,000 cubic yards of
contaminated soil. A decision on the waste pit cleanup is scheduled for November 1994.
Soils and Groundwater: The DOE is investigating the nature and extent of
groundwater contamination at the site. The results of the study will be available in
June 1994. A decision on a remedy is scheduled for July 1995.
Production Area: The DOE is assessing the nature and extent of contamination
in the production area. A decision to remove the building will be finalized in June
1994. The final fate of the building materials will be decided in 1997.
K-65 Silos: The DOE has completed studying the extent of the contamination at
the silos. The results of the investigation, will lead to the selection of appropriate
cleanup remedies in June 1994.
Other Source Areas: The investigation of other source areas was completed
February 1994 and final remedy is scheduled for January 1995.
Alternate Water Supply and Water Treatment: The DOE in conjunction with
the Hamilton County Department of Public Works is providing funding for an
alternate water supply by October 1994.
Site Facts: A Federal Facilities Compliance Agreement was signed in 1986 between the
EPA and the DOE. Pursuant to the Agreement, the DOE is required to conduct a study of
the nature and extent of site contamination and to recommend alternatives for final cleanup.
A Consent Decree was signed in 1988. A new Consent Agreement was finalized in mid-1990,
and it was revised again in September 1991.

Site Description
The Fields Brook site is a 3 1/2-mile channel in a tributary of the Ashtabula River and
collects water from a 5 1/2-square-mile area. A portion of Fields Brook flows through an
industrial area containing a high concentration of diverse chemical plants and serves as the
principal receiving stream for many industrial discharges. The site includes a brook and its
tributaries, and areas bordering the site. From the industrial area, the brook flows through a
residential area to the Ashtabula River. Industrial sources adjacent to Fields Brook have
contaminated the sediments with a variety of toxic chemicals including polychlorinated
biphenyls (PCBs) and heavy metals. The Ashtabula River empties into Lake Erie, 1 1/2 miles
downstream of the site. Lake Erie serves as the potable water source for the City of
Ashtabula. Contaminated sediments threaten drinking water intakes in Lake Erie.
Site Responsibility: This site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 10/22/81

Threats and Contaminants
Sediments taken from the Ashtabula River are contaminated with PCBs, volatile
organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), heavy
metals, and phthalates. VOCs and heavy metals including mercury, lead, zinc, and
cadmium have been detected in surface water from Fields Brook and the Detrex
tributary. Contaminants detected in fish include VOCs and PCBs. The site poses a
potential health risk to individuals who may drink or come in direct contact with
contaminated water from Fields Brook and the Ashtabula River. Ingesting
contaminated fish or sediments also may cause adverse health effects.
Cleanup Approach
This site is being addressed in three long-term remedial phases focusing on cleanup of
sediments, controlling the source of contamination, and investigation of the Ashtabula River.
May 1994
-------
Response Action Status
Sediments: The selected cleanup technologies to address contaminated
sediments include: excavating contaminated sediments from Fields Brook,
subsequent temporary storing and dewatering of the sediments, and using thermal
treatment to decontaminate a portion of the sediments with the on-site landfilling of the
remainder of the sediments; treating wastewater from the dewatering process; and (3) long-
term monitoring. Approximately 36,000 cubic yards of contaminated sediments will be
solidified and 16,000 cubic yards will be thermally treated. Wetlands and F landplains are also
being assessed and potentially remediated under this phase of remediation. Under EPA
monitoring, six of the parties potentially responsible for site contamination are presently
designing the technical specifications for the sediment cleanup. Final sediment cleanup
activities are expected to commerce in late 1995.
Source Control: Under EPA monitoring, six of the potentially responsible parties
currently are conducting a study to identify sources of ongoing sediment and
surface water contamination. The study is planned to be completed in 1994.
Ashtabula River: Five potentially responsible parties, under EPA monitoring, are
conducting an investigation into possible contamination of the Ashtabula River.
The investigation will identify any potential sources of contamination to the river
and harbor and will study the impacts of contamination on the water supply of the City of
Ashtabula. EPA is conducting modeling of the river\harbor system to assess potential for
sediment and risks.Portions of the river may be added to the site if cleanup actions are
required.
Site Facts: In 1989, six of the potentially responsible parties agreed to comply with an order
from the EPA requiring them to design the cleanup technologies to address contaminated
sediments at the site and to study the ongoing sources of site contamination. A separate
order covers the river investigation. The EPA and the State issued a health advisory
recommending that people not eat fish caught in a portion of the Ashtabula River because of
possible contamination.
Environmental Progress
After adding this site to the NPL, the EPA performed preliminary investigations and
determined that no immediate actions were required at the Fields Brook site while further
studies are taking place and cleanup activities are being planned. Currently, investigations are
determining if the Ashtabula River will require cleanup.

Site Description
From the mid-1950s to 1985, residential, commercial, and industrial solid waste was disposed
of at the 30-acre Fultz Landfill site. The site lies in an area that was strip mined for coal in
the late 1940s. Extensive subsurface coal mines also are located near the site. The landfill was
licensed by Guernsey County in 1969 to accept solid waste products. On a number of
occasions during the 1970s, County and State officials cited the owner of the landfill for
violations of the operating license, which included inadequate control of leachate runoff and
unauthorized disposal of drums that contained potentially hazardous liquid waste. In 1978, the
Ohio Environmental Protection Agency found approximately 1,000 drums of hazardous waste
on the property. Because the landfill was not authorized to accept hazardous waste, the State
contacted the businesses generating the drums, requesting that they stop sending drums to
the landfill. The State investigated the site again in 1979 and 1980 and found that leachate
seeping from the site contained phenols and heavy metals. Six ponds lie on the northern and
eastern sides of the landfill. In addition, two streams, Streams A and B, are located nearby.
Both streams discharge to Wills Creek. Residents of Cambridge, 3 miles north of the landfill,
use Wills Creek as a source of drinking water. One municipal water well is located near the
site.

Groundwater contains heavy metals such as arsenic, barium, chromium, and lead;
volatile organic compounds (VOCs); and phthalates. Sediments in two on-site
ponds and leachate are contaminated with heavy metals, as well as low levels of
organic compounds. A shallow aquifer under the site is contaminated with heavy
metals. If pollutants seep into the water supply, people who come in direct contact
with or drink the water may be at risk. Leachate containing heavy metals and
phenols seeps from the landfill into nearby ponds and creeks. Wildlife in or around
these bodies of water may be harmed by the pollutants.
Cleanup Approach
This site is being addressed in a single long-term remedial phase focusing on cleanup of the
entire site.
Response Action Status
Entire Site: In 1991, the EPA completed an investigation of the type and extent
of the contamination at the site. As a result of the study, the EPA selected the
following remedies to cleanup the site: fencing the site, nearby residential well
sampling, leachate collection, capping the landfill, extracting and treating the groundwater.
EPA is currently designing the selected remedies and is expected to initiate actual cleanup
activities in the spring of 1995.
Environmental Progress
After adding this site to the NPL, the EPA performed preliminary investigations and
determined that no immediate actions were required at the Fultz Landfill site. Actual cleanup
will begin once the selected remedies are designed.

Before 1966, the 30-acre Industrial Excess Landfill (IEL) site was used for mining sand and
gravel. Gradually, the mining and excavation pit was converted into a landfill, which operated
at the site from 1966 to 1980. During this time, IEL accepted wastes primarily from the
nearby rubber industries. An estimated 780,000 tons of solid waste and 1,000,000 gallons of
liquid waste were dumped onto the ground at the landfill. The Stark County Board of Health
ordered IEL to stop dumping chemical wastes in 1972. The landfill was closed in 1980. After
the landfill stopped operations, it was covered with soil, and fertilizer was applied to the
surface to help vegetative growth. Before the EPA became involved with the site in 1984,
several State and local government agencies were involved with licensing issues, inspections,
and other response activities at the landfill. The Ohio EPA began an investigation to
determine whether area drinking water was contaminated and if the site posed a health risk
to nearby residents. As of 1989, the population within a 1-mile radius of the site was

Individuals who come into direct contact with or accidentally ingest contaminated
groundwater or soil may suffer adverse health effects.
May 1994
-------
Cleanup Approach
This site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on cleanup of the entire site and the provision of an alternate water supply.
Response Action Status
Initial Actions: Between 1985 and 1988, the EPA installed an active Methane
Venting System (MVS) to control the migration of methane and landfill gases off
site. Additional landfill gas monitoring wells were installed in 1989.
During the installation of the MVS, 53 drums of suspected industrial waste were uncovered.
These drums were subsequently removed from the site and disposed of in an EPA-approved
facility.
After testing completed by the EPA in 1987 showed that ten private residential wells were
impacted by the landfill, the EPA installed air strippers in the affected residences to remove
VOCs from the water. EPA subsequently signed a Record of Decision to provide alternate
water to an area comprised of 100 homes downgradient of the site.
Entire Site: The methods selected by the EPA in 1989 to clean up the site
include: covering the entire site with a cap; expanding the MVS; extracting and
treating contaminated groundwater; pumping groundwater to maintain the water
table at a level that is below that of the wastes in the landfill; fencing the site; placing deed
restrictions on future use of the site; and continued monitoring of the site.
EPA has purchased 22 parcels of land, consisting of 12 residences and 2 businesses. These
properties bordered the site and were needed for implementation of the cap.
EPA is currently in the Remedial Design Phase. Upon completion of the design, estimated
for early 1995, construction of the cap is anticipated to begin in Spring 1995.
Alternate Water Supply: Under order by the EPA, the potentially responsible
parties constructed an alternate water supply system which provides water to 100
homes located downgradient of the site. The system was completed in January
1991.
Environmental Progress
The actions taken to control methane gas migration, removing of drums containing industrial
waste, installing of air strippers, and providing of an alternate water supply have reduced the
potential of exposure to hazardous substances in the drinking water at the Industrial Excess
Landfill site while remaining cleanup activities are underway.

Site Description
The 9-acre Laskin/Poplar Oil Co. site is a greenhouse and waste oil recovery operation that
opened during the late 1890s. By the 1950s, the operation had installed oil-fired boilers to
heat the greenhouses. In the 1960s, storage tanks and pits were installed to store waste oil.
Environmental problems at the site are related to the subsequent storage, handling, and
combustion of waste oil. The EPA and the Ohio EPA discovered contamination at the site in
1977, and much of the on-site oil was removed during the next 5 years. The site contains two
drained ponds formerly used to separate oil, a boiler house, four oil storage pits, one
underground oil storage tank, 32 aboveground oil storage tanks, a retention pond, a
freshwater pond, a greenhouse complex, and other miscellaneous buildings and sheds. Three
small treatment ponds lie near the bottom of the Cemetery Creek ravine, north of the
retention pond. Liquids stored in the tanks and ponds had the potential to overflow, leak, or
collapse because of poor construction and maintenance. Any contaminants released would
enter Cemetery Creek. The creek is a tributary of Mill Creek, which flows into the Grand
River. Drinking water is drawn from the Grand River in Harpersfield Township,
approximately 11 1/2 miles downstream of the site.

boiler house was contaminated with dioxin. The surface water in the on-site
retention pond was contaminated with low levels of acetone in addition to arsenic,
mercury, and other heavy metals. A potential health threat existed if accidental
ingestion of contaminated soils and surface water had occured. There was also a
possibility that contaminants may enter the food chain and contaminate meats and
vegetables that are raised locally.
May 1994
-------
Cleanup Approach
This site is being addressed in three stages: initial actions and two long-term remedial phases
focusing on cleanup of ponds, structures, and soils, as well as other areas of surface
contamination.
Response Action Status
Initial Actions: In 1980, the EPA stabilized the site by treating the water from
the pond through a sand filter and activated carbon system. The treated water
was discharged to Cemetery Creek. When oil-contaminated water from a pond
overflowed into the creek, the oil was recovered with sorbent booms. The pond and tanks
were covered. From 1982 to 1986, various actions were performed at the site including:
removal of 300,000 gallons of contaminated oil; on-site treatment of 400,000 gallons of
contaminated wastewater; on-site containment of 205,000 gallons of contaminated sludge;
removal of an additional 250,000 gallons of wastewater and oil; removal of contaminants from
one pond; and removal of approximately 100 drums containing hazardous wastes. The
potentially responsible parties removed 450,000 gallons of oil and wastewater from the pits
and tanks in 1985 and 1986. Later in 1986, they sampled the residues left in the pits and
tanks and conducted additional soil borings. In 1987, the EPA repaired the existing fence
around the site and the leaks found in the covers of the underground tanks.
Ponds, Structures, and Soils: The EPA chose the following methods for
cleanup: drain the retention and freshwater ponds, discharge the surface water
from the ponds to Cemetery Creek, with treatment if required; backfill freshwater
ponds with clean fill and grade the retention pond area; thermally treat contaminated soil,
ash, and debris from the boiler house area and dispose of the ash in an on-site landfill;
demolish and thermally treat or decontaminate dioxin-contaminated structures, or if this
material cannot be decontaminated or thermally treated, it will be contained in an on-site
concrete vault and placed beneath the cap for temporary storage until proper effective
disposal can be secured for the material; construct a groundwater diversion trench uphill from
the contaminated soil and groundwater; construct a multi-layer cap over soils; dewater the
site by natural groundwater flow to Cemetery Creek; monitor groundwater and surface water
to assess the quality of groundwater migrating to Cemetery Creek; and impose access and
land use restrictions. Design of these cleanup activities was completed in 1992. The cleanup
activities were completed in September 1993.
Surface Contamination: Based on the results of the site investigation, the EPA
selected several remedies to address surface contamination. The cleanup strategy
for this portion of the site includes: constructing a fence around contaminated
portions of the site and the incinerator; incinerating oils, sludges, and contaminated soils, with
the safe disposal of all incinerator ash; dismantling and disposing of all tanks and cinder
blocks in the pits; and regrading the site to prevent ponding in the excavated areas. The
potentially responsible parties, under EPA monitoring, completed the cleanup work by
December 1992.

Environmental Progress
The removal of contaminated oil, wastewater, and drums, along with the treatment of
contaminated wastewater and contaminated sludge, have reduced the potential for exposure
to hazardous substances at the Laskin/Poplar Oil site. In the early 1990's, the treatment of
the ponds, structures, soils, oils, and sludges along with the cappings of the site and
groundwater diversion trench have virtually eliminated the potential for exposure to
hazardous substances.

Site Description
EPA REGION 5
Miami County
2 miles north of Troy
The 65-acre Miami County Incinerator (MCI) site contains five areas of concern: the South
Landfill, the North Landfill, the Liquid Disposal Area, Contaminated Groundwater, and the
Ash Disposal Pit and Ash Pile. Other important features of the site include an area of visibly
stained soil near the incinerator building, a former scrubber wastewater lagoon, and sediment
in the Eldean Tributary. The incinerator and landfill were opened in 1968 to process and
dispose of municipal and industrial wastes. Combustible wastes were to be incinerated and
non-combustible wastes were to be landfilled. However, large volumes of combustible wastes
were landfilled along with non-combustible wastes. The facility generated scrubber wastewater
and ash quench water, which were disposed of in the wastewater lagoon. Incinerator fly ash
and bottom ash, non-combustible materials, and unburned refuse were disposed of in a
landfill north of the tributary, and liquid wastes, including waste oils and solvents, were
dumped or buried on site. MCI was ordered by the Ohio EPA to cease the disposal of liquid
waste by 1974. The site stopped accepting liquid wastes in 1975, and all landfill operations
ended in 1978. The incinerator building now serves as a solid waste transfer station. The
Eldean Tributary of the Great Miami River runs across the northwestern corner of the site.

Threats and Contaminants
Volatile organic compounds (VOCs) and heavy metals including arsenic, barium,
and cadmium were detected in groundwater near the Liquid Disposal Area.
Sediments along the unnamed creek are contaminated with pesticides and
polychlorinated biphenyls (PCBs). VOCs, polycyclic aromatic hydrocarbons
(PAHs), PCBs, dioxins, pesticides, and heavy metals including arsenic, lead,
cadmium, and chromium were detected in soil below the surface of the Liquid
Disposal Area. Potential health risks exist for those who ingest contaminated water
or the contaminated soil. Cleanup workers and children playing on the site may be
most at risk. However, the site does have ground cover, lessening the opportunity
for direct contact with the soil.

-------
Cleanup Approach
This site is being addressed in two stages: immediate actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Immediate Actions: Three residences, the Miami County Highway garage, and
the incinerator facility were provided with alternate water supplies in 1986. Other
affected residences were provided with alternate water supplies in 1989.
Entire Site: In 1989, the EPA selected the following remedies for each area of
concern. For the South Landfill and the North Landfill, the EPA will construct a
single-barrier clay cap to prevent direct contact with the contaminants and
decrease infiltration of rainwater to reduce the potential for groundwater contamination. The
Ash Pile will be cleaned up by removing contaminated soil, treating it if necessary, and
placing the material into the North or South Landfill before construction of the cap. The Ash
Disposal Pit will be capped. Soil vapor extraction, groundwater pumping and treatment, and
capping will be used to treat the Liquid Disposal Area and Contaminated Groundwater Area.
Soil vapor extraction will reduce the risk of future VOC releases and reduce the volume of
contamination in the soil. Groundwater pumping and treatment will reduce the volume of
contamination in groundwater within and downgradient of the Liquid Disposal Area. All of
the remedies include construction of a fence to reduce the potential for site access and land
use restrictions to prevent future exposure to contaminants. The parties potentially
responsible for the contamination are expected to complete the engineering designs by 1995
for the South Landfill and 1996 for the rest of the site.
Environmental Progress
By supplying an alternate water supply, the potential of exposure to hazardous substances in
the drinking water has been eliminated, and residents near the Miami County Incinerator site
will continue to be protected until planned cleanup activities are completed.

Site Description
The 44-acre Nease Chemical site was used for the manufacturing of pesticides, fire
retardants, cleaning compounds, and pharmaceutical products since 1961. The major product
was the pesticide mirex. The plant closed the production facilities in 1973 and completed site
closure activities in 1975. In 1982, a report indicated that contaminants had migrated from
the site and drums had been buried on the site. Following approval from the EPA in 1983,
the company removed the buried drums and associated contaminated soils from the site and
soils from a barren area. In addition, the company removed soil from an abandoned pond and
a freshwater ditch running parallel to the main railroad line. Between 1983 and 1984,
additional monitoring wells and soil borings were drilled to further define the hydrogeology
and groundwater quality. Residences are located near the site. Feeder Creek, located on the
site, drains into the Middle Fork of Little Beaver Creek, where a 1987 EPA investigation
verified sediment and fish contamination. These creeks drain into the Ohio River.

Groundwater, soil, and sediments are contaminated with volatile organic
compounds (VOCs). A 1987 EPA study showed contamination of fish, creek and
adjacent floodplains sediments with mirex, a pesticide and fire retardant. Dairy
herds on two nearby farms were affected by exposure to creek contamination.
Access to the site now is restricted by fencing and bridges. In 1989, the Ohio
Department of Health (ODH) detected concentrations of mirex, a site-related
contaminant, in the bloodstream of some local residents/workers tested. The
ODH subsequently issued a health advisory for fishing and swimming along certain
portions of the Middle Fork Little Beaver Creek.

-------
Cleanup Approach
This site is being addressed in three stages: initial actions and removal actions to control the
source, and a long-term remedial phase focusing on cleanup of the entire site.
Response Action Status —
Initial Actions: Several voluntary initial cleanup actions have been completed to
locate and remove the main sources of contamination at the site. Earlier cleanup
actions conducted by the company included the removal of contaminated contents
of the waste ponds and buried drums located on the site, along with associated soils. In
addition, intermediate level activities were begun to minimize migration of contaminants off
site. These activities include leachated collection and surface water management. In
November 1993, voluntary initial activities were terminated.
Removal Actions: Source control actions have been expanded under the U.S.
EPA removal program following the termination of voluntary actions. The
leachate collection and surface water management measures expanded to include
continous leachate collection of the entire property. In addition, on-site leachate and
groundwater treatment has been implemented.
Entire Site: Under EPA monitoring, the parties potentially responsible for the
contamination initiated an investigation in 1988 to determine the nature and
extent of site contamination and to identify alternative cleanup methods. A
preliminary assessment indicates that any remaining contaminated soil will require removal
and contaminants will need to be separated from groundwater. Additionally, a groundwater
containment system needs to be implemented. The final cleanup remedy for the site will be
selected once the investigation is completed, scheduled in 1994.
Environmental Progress
All Remedial Investigation activities have been completed. Initial cleanup actions have
removed the immediate sources of contamination and have reduced the potential for nearby
residents to be exposed to hazardous wastes left at the Nease Chemical site while cleanup
activities are being planned.

Site Description
Operations began at the 40-acre New Lyme Landfill site in 1969 and were initially managed
by two farmers. In 1971, the landfill was licensed by the State of Ohio, and operations were
taken over by a licensed landfill operator. The site received various wastes and construction
and demolition debris. However, numerous violations of the license occurred, including open
dumping, improper spreading and compacting of wastes, no State approval for disposal of
certain industrial wastes, and excavation of trenches into the shale bedrock. In 1978, the
landfill was closed by the Ashtabula County Health Department. Wastes at the site included
asbestos, coal tar, resins, paint sludge, oils, corrosive liquids, acetone, volatile organic
chemicals (VOCs), chlorinated solvents, and laboratory chemicals. Leachate containing
organics discharged from two sides of the fill area and threatens nearby surface waters. There
is also concern that groundwater might be contaminated by leachate from the landfill. Ten
families live within 1/4 mile of this site. Three households are presently using groundwater as
their drinking water source. Lebanon Creek and a wetland known as the New Lyme Wildlife
Area are located near the site.

Threats and Contaminants
The groundwater is contaminated with VOCs and phenols. Sediments in Lebanon
Creek, the wetlands, and leachate seeps have been exposed to VOC, lead, and
chromium contamination by surface runoff during site operations and leachate
seep discharge. Surface soil samples from the central and eastern portion of the
site contained VOCs. One soil sample contained polychlorinated biphenyls (PCBs).
Potential health risks may exist for individuals accidentally ingesting or touching
the contaminated groundwater, soil, sediments, or leachate. Lebanon Creek, other
area surface waters, and area wetlands may be threatened by the site
contamination.

-------
Cleanup Approach
This site is being addressed in a long-term remedial phase focusing on cleanup of the entire
site.
Response Action Status
Entire Site: In 1985, the EPA selected the following cleanup actions for the site:
construction of a cap over the landfill; installation of extraction and containment
wells around the perimeter of the landfill to dry up the landfill and to eliminate
leachate production; on-site treatment of contaminated groundwater and leachate; on-site
consolidation of contaminated sediments; installation of gas vents; fencing of the site; and
installation of a groundwater monitoring system. The wastewater treatment plant was
constructed in late 1990. The treatment plant currently is operating, however, modifications
are being made to make the plant more efficient. These modifications are expected to be
completed in early 1994. All other cleanup activities at the site were completed in 1990.
Environmental Progress
The completed cleanup activities, including the construction of the cap in 1990, have reduced
the potential for exposure to hazardous substances at the New Lyme Landfill site while the
water treatment plant for the final phase of the site cleanup plan is put into full operation.

The North Sanitary Landfill, Inc. (NSL) site is located at 200 Valleycrest Drive in Dayton,
Montgomery County, Ohio. The site occupies 101.9 acres, approximately 45.7 of which were
used as a landfill. Several industrial facilities, including bulk oil storage terminals, an
industrial laundry facility, car crushing facility, a former industrial plating facility and a
demolition debris landfill are located adjacent to the NSL property.
The NSL site, also known as the Valleycrest Landfill, was owned by the Keystone Company,
Inc., which operated a sand and gravel mining operation from the 1940s until the 1970s.
Between 1966 and 1975, landfill operations at the site were conducted by E.G. Davis Co.,
Inc., under the name of NSL, Inc. Waste Management, Inc. of North America purchased the
E.G. Davis Co. in 1983.
Industrial and municipal wastes from the Dayton area were used at NSL to fill unlined gravel
pits that were created by former mining operations. These pits contained water that may
have entered the sand and gravel aquifer that the pits intersect. The following wastes were
deposited at the NSL site: electrical transformers, burned foundry sand, demolition debris,
slag, baghouse dust, plaster, rubber tires, lampblack, grindings from the brake shoes (possible
containing asbestos), waste from a local sewer cleaning company, and drums of chemicals.
Lead, mercury, cyanide, and PCBs were detected in wastes disposed of at the site. While
operating the landfill, NSL was cited for repeated violations such as inadequately covering
wastes, accepting hazardous wastes for which it was not permitted, and accepting burnable
wastes (numerous onsite fires have occurred). These citations were issued by State and local
health departments. According to the Miami Conservancy Regional Planning Commission
District and the Ohio Environmental Protection Agency, thousands of drums were buried
onsite

four concrete silos, which were removed as part of the site cleanup. This property became
contaminated when drummed waste and potting soil additives were improperly stored. The
Kraus Property was partially covered with piles of railroad ballasts and had one empty
abandoned bulk liquid tank. Wastes from the Henfield Property were stored on the Kraus
Property with the owner's permission. In 1979, the EPA and Ohio EPA found approximately
1,200 drums of toxic waste, including solvents, oils, resins, and polychlorinated biphenyls
(PCBs) stored on both properties. The drums leaked, causing contamination of soil and
groundwater. Approximately 100 homes are within a 1/4-mile radius of the site. An estimated

This site is being addressed in two stages: immediate actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Immediate Actions: In 1981 and 1982, some of the parties potentially
responsible for site contamination voluntarily removed 580 drums of wastes. Later
in 1982, all remaining drums were removed, and contaminated soil was removed
from the drum storage area. Soil and well water samples were taken and analyzed. In 1984, a
security fence was installed around the site.
Entire Site: In 1985, the EPA selected the following cleanup remedies: removal
and off-site disposal of a select volume of contaminated soil; extraction and
treatment of contaminated groundwater; aquifer use restrictions; and provision of
an alternate water supply for one residence. By 1989, the EPA had removed the
contaminated soils and installed the groundwater collection and treatment system. The silos
and buildings, drums, and tanks were removed, and debris was taken to an off-site disposal
facility. In 1992, it was determined that contamination levels in the shallow ground water of
the Kraus property were higher than expected. In November 1992, a field investigation was
conducted to determine the full extent of the volatile organic plume on the Kraus property.
Piezometers were installed in May 1993 to verify ground water flow directions. In Spring
1994, an extension to the extraction trench will be constructed to ensure that all
contaminated ground water will be captured and treated. Groundwater will continue to be
pumped and treated until established cleanup goals are met. Area residents utilize the
municipal water supply.
Environmental Progress
The removal of contaminated soil and debris has eliminated the surface contamination at the
Old Mill site. The groundwater will continue to be treated until contaminant levels meet the
cleanup standards specified in the remedy.

The 200-acre Ormet Corp. site is an aluminum processing facility that began operating in
1958. Between 1958 and 1968, approximately 85,000 tons of spent potliner material were
stored in an unlined, open storage area. From 1968 until 1981, Ormet Corp. operated a
caustic digestion process to recover chemicals from the potliner material. Since 1981, spent
potliner material has been transported off site for disposal. From 1958 to 1981, as many as
five unlined disposal ponds were used to hold waste materials at the site. Untreated water
from the facility, as well as contaminated groundwater, empties into the Ohio River. The
Ohio River is a major industrial waterway, recreational area, and source of drinking water for
many communities along its banks. Approximately 1,500 people live within a 3-mile radius of

Response Action Status
Entire Site: In 1987, the'EPA and the Ohio EPA began an investigation to
identify the types and amounts of contaminants on and near the site. The
following activities were completed during the first phase of the investigation:
samples of surface water, groundwater, surface soils, and sediment were collected at and near
the site and were tested; air quality at certain locations was analyzed; and data from previous
investigations of the site were reviewed to assist in identifying contaminants present at the
site. The second phase of the investigation included the following activities: groundwater
sampling, which included low-level PAH analysis of contaminated groundwaste; investigating
the construction material scrap dump to define the types of contaminants within and
originating from this area; investigating the carbon runoff and deposition area to define the
boundaries of the area and to determine the thickness of the carbon material; and sampling
the Ohio River sediment to define the extent and type of contamination. The Phase II RI
also included the completion of an ecological inventory for determining any risks posed to
ecological receptors. The Ormet Corp., under EPA and Ohio EPA monitoring, will evaluate
the best ways to address contamination problems found at the property. The investigation,
which was completed in Spring 1994, provides the basis for selecting a cleanup method for the

the soil and sediments include VOCs, polycyclic aromatic hydrocarbons (PAHs),
heavy metals, and pesticides. Surface water contaminants include VOCs, PAHs,
phenols, and heavy metals. The presence of trace levels of VOCs in groundwater
does not present an immediate health risk to people. Other contaminants are
present at levels low enough not to constitute a health concern. Contaminated
runoff from the site to Mill Creek may pose a problem.

This site is being addressed in two stages: initial actions and a long-term remedial phase
focusing on cleanup of the entire site.
May 1994
-------
Response Action Status
Initial Actions: From 1980 to 1983, Pristine, Inc., under the monitoring of the
State, removed much of the waste at the site. In 1984, some of the parties
potentially responsible for site contamination, under EPA monitoring, performed
soil, sludge, sediment, and waste removal activities to address immediate hazardous site
conditions.
Entire Site: In 1987, the EPA selected the following cleanup technologies to
address both the soil and groundwater contamination: treatment of the top one
foot of soil across the site and all other soils from the present groundwater surface
to 4 feet below the ground surface by in-situ vitrification, whereby the soil is electrically
melted to bind the waste in a glassy solid material; treatment of sediments and waste pit soils
if necessary, and placement of ash under an on-site cap, if necessary; performance of an
additional groundwater investigation and extraction and treatment of the lower aquifer with
wells, an air stripper, and carbon adsorption; decontamination and demolition of on-site
structures and disposal of debris in a sanitary landfill; construction of a fence to restrict
access; implementation of deed restrictions to restrict land use; and monitoring of
groundwater flow and quality. In 1990, the EPA revised the remedy to treat the contaminated
soil by incineration and in-situ soil vapor extraction rather than in-situ vitrification. The soil
vapor extraction process removes VOCs from the soil by placing a cover over the
contaminated area and applying a vacuum to filter the contaminants from the soil particles.
The demolition of on-site structures was completed in early 1991 by the potentially
responsible parties, under EPA monitoring. The designs for the incinerator, the soil vapor
extraction system, and the groundwater treatment system began in 1991. Once the design for
the incinerator was completed in early 1993, it was determined that a thermal desorption unit
could treat the soil. Thermal desorption is a process somewhat like baking by which
containminants are separated from the soil by heat and then disposed of off-site. Thermal
desorption was chosen to treat the site soils by the responsible parties in mid 1993 and the
treatment of soil was completed in March 1994. A total of 13,000 tons of soil was treated by
the thermal desorption unit. Design of the soil vapor extraction system is near completion
and construction should begin during the Summer of 1994. Startup of the soil vapor
extraction system should begin in early 1995 and it is scheduled to operate between seven and
ten years. In mid Summer 1994, a temporary groundwater extraction system will begin
treating the lower aquifer groundwater. The final groundwater pump and treatment system
will begin startup concurrently with the soil vapor extraction system.
Site Facts: From 1980 to 1983, much of the on-site waste was removed in accordance with a
Consent Decree entered into between the State and Pristine, Inc.

The removal of waste, soil, sludge, and sediment has reduced the potential for exposure to
hazardous substances at the Pristine, Inc. site while final cleanup actions are being conducted.

Site Description
EPA REGION 5
Lorain County
Elyria
The Republic Steel Corp. Quarry site consists of a 4-acre quarry containing water that is
surrounded by 7 acres of fenced property. Prior to 1950, the site operated as a sandstone
quarry. The site then was used for the disposal of spent pickle liquor. Pickle liquor is an acid
used to dissolve oxides in the mill scale that forms on steel during the hot rolling process.
Sulfuric acid was used as the pickling acid at this facility. From 1950 to 1972, approximately
200,000 gallons of waste pickle liquor were discharged into the quarry each year. Waste pickle
liquor reportedly was pumped through an aboveground pipe to a ditch located on the eastern
side of the plant. The ditch routed the liquid north to the quarry. Beginning in 1969, the
operators stopped discharging the pickle liquor into the quarry, and it was hauled off site.
From 1969 to 1975, the ditch continued to be used to direct wastewater from the plant to the
quarry. In 1976, the ditch was dammed. The site, although fenced, is still accessible.
Approximately 60,000 people live within 3 miles of the site. The City of Elyria Water
Company supplies treated water for all water users within 3 miles of the quarry, except for
360 homes. Of these 360 homes, 150 are served by the Rural Lorain County Water
Authority. Both of the water companies obtain their water supplies from Lake Erie. The
remaining 210 homes obtain water from private wells. Two residential wells are within 1 mile
of the site. Both the on-site quarry and the Black River are used for recreational purposes.
Site Responsibility: This site was addressed through
Federal and State actions.

Threats and Contaminants
Groundwater and surface water were contaminated with heavy metals including
barium, manganese, and iron. Groundwater still contains beryllium. Quarry
sediments were contaminated with volatile organic compounds (VOCs), heavy
metals, and phthalates. Heavy metals, phthalates, oil and grease, and pyrene were
contaminating the soil. Health risks included accidentally ingesting or coming in
direct contact with contaminated groundwater, surface water, soil, or sediments.
May 1994
-------
Cleanup Approach
This site was addressed in a long-term remedial phase focusing on cleanup of the entire site.
Response Action Status
Entire Site: In 1988, the EPA selected the following cleanup technologies to
address soil contamination: excavation of contaminated surface soil from the pickle
liquor discharge ditch and the southern end of the quarry; disposal of excavated
soil; a five-year monitoring plan including a fish species survey and fish tissue study to ensure
the absence of contaminants; and groundwater monitoring. Approximately 130 cubic yards of
contaminated soil were removed and disposed of in a regulated hazardous waste landfill.
Groundwater was resampled and fish tissue samples were collected to better assess risks at
the site. The EPA and the State are in the process of determining if the presence of
beryllium in the groundwater at the site warrants any further action; however, it is anticipated
that no further action will be necessary. The site is planned for deletion from the NPL. A
final closeout report was prepared in December 1992. The extent of the contamination and
the likelihood that the groundwater will be used as a potable water source will be evaluated
before site deletion proceeds.
Environmental Progress
All planned cleanup activities have been completed, and contaminated soils at the site have
been safely removed. The EPA currently is in the process of evaluating the cleanup activities
performed at the Republic Steel Corp. Quarry to ensure that any future usage of the site
does not pose a risk to public health and the environment. The site is scheduled to be deleted
from the NPL by the close of 1992. A five-year review is scheduled to begin during 1994.

Site Description
The 78-acre Skinner Landfill site is located on a ridge above the east fork of Mill Creek in
West Chester. The landfill accepted hazardous and demolition wastes since the late 1950s.
The actual landfill area covers approximately 10 acres and includes a lagoon less than 1 acre
in size, containing hazardous waste and approximately 100 drums of solvents, pesticides, and
heavy metals. Approximately 40 feet of demolition material are on top of this lagoon.
Demolition waste was accepted until July 1990. The remaining 60 acres of the site contain
scrap metal, the owner's residence, and buildings used by the owner for his general
contracting business. Two wells located downgradient from the lagoon are contaminated with
VOCs. Approximately 3,000 people live within 3 miles of the site. On-site residences use
groundwater upgradient from the landfill area for drinking water. The majority of off-site
residences are connected to a municipal water supply. A fork of Mill Creek borders the site
to the East and Skinner Creek borders it to the West. The potential exists for wildlife in the
creeks to become contaminated from migrating contaminated sludge.
Site Responsibility: The site is being addressed through
Federal actions.
NPL LISTING HISTORY
Proposed Date: 12/30/82
Final Date: 09/08/83
Threats and Contaminants
Liquid sludge in the on-site lagoon is contaminated with heavy metals including
cyanide, cadmium, and chromium; volatile organic compounds (VOCs) and semi-
volatile organic compounds; pesticides; polychlorinated biphenyls (PCBs); dioxins;
and furans. Groundwater is contaminated with various VOCs and semi-volatile
organic compounds. Two creeks which border the site contain sediments
contaminated with VOCs from sludge migration. Potential health threats include
accidental ingestion of and direct contact with contaminated liquid sludge,
groundwater, or river sediments.
May 1994
-------
Cleanup Approach
The site is being addressed in a single long-term remedial phase focusing on cleanup of the
entire site.
Response Action Status
Entire Site: The EPA completed the second phase of an investigation into the
nature and extent of site contamination. The investigation, which began in late
1988, has defined the contaminants of concern and recommended alternatives for
the final cleanup. The investigation was completed in mid-1992. The proposed remedy
includes: excavating portions of the waste lagoon; incinerating and solidifying excavated
materials; redepositing treated materials and constructing a multi-layer cap; potential for
conducting soil vapor extraction to remove VOCs from landfill soil; and collecting and
treating groundwater. In the meantime, an interim remedy is in effect. It includes fencing the
site to prevent migration of contaminated sludges off-site, and providing hook-ups to the city
water supply for area residences who might become affected by contaminated groundwater.
The proposed remedy was finalized as a Record of Decision (ROD) in June 1993. The ROD
replaced incineration and solidification of portions of the waste lagoon with incorporating the
buried lagoon under the multi-layer cap.
Environmental Progress
An initial evaluation of the Skinner Landfill site determined that no immediate actions were
needed during the investigation leading to the selection of final cleanup remedies. EPA is
attempting to proceed with the remedial design under the terms of a two party Administrative
Order on Consent between the PRP group and EPA.

Site Description
The 75-acre South Point Plant site is an active ethanol producing facility. Ammonia, fertilizer,
and formaldehyde were produced on site from 1943 to 1979. The Federal government began
operations at the site in 1943 with the production of chemicals used in explosives. The Allied
Chemical Corporation operated the plant for the military until 1946, when the company
purchased the property. From 1946 until the plant closed in 1979, Allied Chemical
Corporation produced chemicals used for agricultural and other purposes. In 1982, South
Point Ethanol built an ethanol production plant and began operations on the site. Several
unlined landfills, covering approximately 20 acres, and surface impoundments were used for
process waste disposal. The landfills were closed in 1979; one is eroding. Numerous activities
have contributed to groundwater contamination. In the late 1950s, a large volume of water
used to extinguish a fire in the ammonium nitrate building caused two incidents of surface
water runoffs. In 1971, an on-site spill of 300,000 gallons of ammonium nitrate occurred.
Access to the site is unrestricted by the Ohio River Bank. Approximately 65,000 people live
within 3 miles of the site. The site is located on the eastern flood plain of the Ohio River.
Surface water from the facility drains to the Ohio River through Solida Creek or the surface
water drainage system. The intake for the Ashland, Kentucky municipal water supply is
located on the Ohio River a mile downstream from the site. The Village of South Point
draws its water supply from two well fields, one of which is located between the site and the
Ohio River. The underlying aquifer that supplies potable water to the Village of South Point
is contaminated.

The 115-acre Summit National site is located on a former coal strip mine containing a coal
wash pond and a coal stock pile. From 1974 to 1978, the site was used as a waste disposal
facility and received such wastes as oils, resins, paint and metal plating sludges, flammable
solvents, and chlorinated solvents. In addition, two surface water ponds and an incinerator
were located on site. The facility received liquid wastes, which were stored in drums, an open
pit, or bulk tanks. Some wastes were incinerated, others were buried, and some were dumped
on the soil. In 1975, the Ohio EPA investigated a complaint of unauthorized discharge from
the site. In 1978, the facility was ordered to stop receiving waste materials and to remove all
liquid wastes from the site. In 1979, surface water monitoring revealed violations of State
water quality standards. Approximately 4,500 people live within 3 miles of the site. There are
several agricultural fields located within a few thousand feet of the site. Berlin Lake
Reservoir is located about 1 mile southeast of the site. The site is enclosed by a fence with

The groundwater is contaminated with various volatile organic compounds (VOCs),
phenols, and phthalates. VOCs, phenols, and heavy metals including cadmium and
antimony are contaminating the soil. The surface water is contaminated with
VOCs, phenols, polycyclic aromatic hydrocarbons (PAHs), polychlorinated
biphenyls (PCBs), and heavy metals including arsenic and chromium. The
contaminated groundwater, soil, and surface water could pose a health problem if
accidentally touched or swallowed. The Berlin Lake Reservoir is a standby water
supply for the City of Youngstown. The reservoir is threatened, because a
contaminated waste lagoon overflowed into the tributary of the reservoir.
Cleanup Approach
This site is being addressed in two stages: immediate actions and a long-term remedial phase
focusing on cleanup of the entire site.
May 1994
-------
Response Action Status
Immediate Actions: In 1980, the EPA removed contaminated materials that
threatened the Berlin Lake Reservoir. Also, drums, tanks, various surface debris,
and a small amount of contaminated surface soil were collected and shipped off
site. All drums, bulk containers, and the concrete block pit were emptied and removed. A
slope was built on the site to control the stormwater runoff. In 1987, the EPA contained a
threatened release of hazardous materials by treating liquid wastes in ponds that were
threatening to overflow, recovering and disposing of an underground storage tank, increasing
the freeboard, strengthening the dikes around the pond, and excavating the underground
tank. Contaminated soils were stored on site and will be treated in the final stages of cleanup
operations.
Entire Site: The parties potentially responsible for the contamination will assume
the responsibility for site cleanup. The selected cleanup remedies for this site
include: excavation and on-site incineration of approximately 24,000 cubic yards of
contaminated soil and sediments and the contents of approximately 1,600 buried drums and 4
tanks, with disposal of incinerator residuals on-site if appropriate tests are passed;
groundwater pumping and treatment using a trench system and extraction well system;
surface water treatment on site; discharge of treated water to downslope surface water;
installation of a permeable cap over the site with regrading and revegetation; dismantling and
on-site disposal of all on-site structures; access and deed restrictions to restrict land uses; and
groundwater and surface water monitoring and residence relocation. The Remedial Design
was completed in June 1993 and the Remedial Action began in July 1993.
Site Facts: In 1981, the State and the potentially responsible parties reached an agreement
to undertake a surface cleanup of the site.
Environmental Progress
The removal of contaminated materials, control of runoff, treatment of liquid wastes, and
strengthening of the dikes by the EPA have reduced the potential of exposure to hazardous
materials at the Summit National site while cleanup activities are being designed.

Response Action Status
Immediate Actions: In 1985, the potentially responsible parties hooked up all
residences with contaminated wells to municipal drinking water supplies. In 1985,
contaminated soils and sediments from the former disposal areas were excavated
and disposed of in an on-site secured landfill. A PCS vault was built on the site to secure
excavated toxic materials, and a soil cap was placed over the concrete-lined vault. TRW
excavated the soils and sediments for placement in the vault.
Groundwater: In 1986, the parties potentially responsible for the contamination
started operating a system that pumps contaminated groundwater to the surface,
treats it with an air stripper, and discharges the treated water to the Sandy Creek.
The groundwater treatment system is currently operating. It is estimated that the cleanup
process will take more than 30 years.
Site Facts: In 1985, the State issued an Administrative Order on Consent to the potentially
responsible parties, requiring that the parties clean up the groundwater.
Environmental Progress
The provision of an alternate water supply, disposal of contaminated soils, securing of toxic
materials, the placement of a cap, and the operation of the groundwater treatment system
have reduced the potential for exposure to contaminated materials at the TRW, Inc.

From 1948 until 1980, the 25-acre United Scrap Lead Co., Inc. site was used to reclaim lead
batteries. An estimated 32,000 cubic yards of crushed battery cases were generated and used
as fill material. The battery acid and the rinse water were disposed of in an infiltration pit.
Beginning in 1972, the acid was neutralized with ammonia prior to discharge into the pit. In
1974, the State recommended implementing a more effective on-site treatment system.
United Scrap Lead did not implement the suggested treatment because operations ceased,
and the facility was closed shortly thereafter. Monitoring wells on site are contaminated with
lead. The site is partially fenced and consists of three general areas: an open flat area
occupying the northern half of the site, a wooded area in the southeastern quarter of the site,
and the southwestern quarter of the site where the offices, process buildings, and waste
disposal areas are located. Forming the southern boundary of the site is a ditch that flows

Cleanup Approach
This site is being addressed in two stages: emergency actions and a long-term remedial phase
focusing on cleanup of the entire site.
Response Action Status
Emergency Actions: In 1985, the EPA excavated contaminated soil and battery
casings from the western portion of the site and moved them away from nearby
residents to the interior of the site. In 1991, via an Administrative Order by
Consent, a fence was installed around the entire site to reduce exposure by means of direct
contact with contaminated materials.
Entire Site: In 1988, the EPA selected the following remedies for the site
cleanup: excavating and treating soil and battery casings by washing, with lead
recovery and off-site disposal or recycling of casing residues and replacement of
cleaned residual soil on site; dewatering tributary sediments, followed by on-site disposal with
treated soil; constructing a soil cover over treated material and revegetating the area;
decontaminating buildings and debris, followed by off-site disposal; installing a new residential
well; imposing deed restrictions; and monitoring groundwater and surface water. The EPA is
expected to complete the design specifications for the cleanup in 1994. In 1992, Phase I-
Remedial Action began. This action includes implementing sections of the selected remedies:
removal of nonhazardous surface debris from on-site, cover hattery casings and excavated
soils, installation of residential well.

focusing on contaminants in groundwater, soils, and surface waters on and near
the site. The investigation was initiated by the potentially responsible parties in 1988. The
EPA assumed responsibility for completion of the investigation from the parties in 1990 due
to dissatisfaction with the course of the investigation. At the conclusion of the study in 1992,
alternatives for site cleanup were recommended. In March 1994, EPA selected a remedy
which requires the consolidation of all wastes in several areas of the site which contain
contaminated soils. Wastes which are not suitable for on-site containment or can be salvaged
will be taken off-site for disposal. The remaining materials will be capped, and groundwater,
surface water, and sediments will be monitored to assure that removal and capping of source
materials is adequate to meet all cleanup levels. Some sediments will be bioremediated to
enhance the breakdown of organic contaminants. Remedial action should begin in 1995.
Site Facts: In 1984, the owner of the site agreed to stop accepting solid and hazardous
wastes and to stop filling, grading, excavating, or burning wastes.

Response Action Status
Emergency Actions: Base residents near one landfill are being relocated, due
to the unstable nature of high levels of methane in the soil. Sixteen base wells use
air strippers to remove contamination. However, the air strippers currently are
not in operation due to mechanical problems. Even so, the drinking water has remained safe.
Approximately 400 drums were removed from various landfills, and the recovery of free
product at a fuel spill site has begun. Based on the results of a study completed in 1990, the
Air Force began operating a pump and treat system for VOCs in the groundwater in late
1991. Free-product recovery system in North East area, started Summer of 1993.
Landfills 8 & 10: The Air Force began an investigation to determine the type
and extent of contamination at these landfills in 1990. At the conclusion of the
investigation, scheduled for 1993, recommendations will be made for cleaning up
these areas. A temporary leachate collection system has been installed. A ROD was signed
July 1993, and the following RA selections:
Operabale Unit 1
1) landfill cap
2) landfill gas collection and treatment
3) leachate and ground water collection and treatment
4) institutional controls

OHIO
EPA ID# OHD980794598
EPA REGION 5
Muskingum County
Northeast of Zanesville
Site Description
The 1-acre Zanesville Well Field site supplies water to the City of Zanesville and is adjacent
to the Muskingum River. In 1981, the State found that three of the 13 production wells were
highly contaminated. A groundwater study conducted by the EPA identified trichloroethylene
(TCE) as a primary contaminant. The City took the three contaminated wells out of service
and began flushing to remove contaminants remaining in the water lines. By 1982, the
contaminated wells still were not in use, but were being continually pumped to reduce the
contamination and to prevent its further migration into the well field. A nearby production
well also was not in use because of the danger of contamination. The City conducts a regular
monitoring program at the site. A neighboring industry, after studying its operation, began to
excavate buried wastes and to treat local groundwater. Approximately 40,000 people reside
within 3 miles of the site. Fourteen city wells supply water to the population.
Site Responsibility: This site is being addressed through
Federal and potentially responsible
parties' actions.
NPL LISTING HISTORY
Proposed Date: 12/30/82
