                      DESCRIPTIONS OF 106 SITES PLACED ON THE
                   FINAL NATIONAL PRIORITIES LIST IN AUGUST 1990

       This document consists of descriptions  of the 106 sites  (including 23
   Federal facility sites) placed on the final  National Priorities List  (NPL) in
   August 1990.  Also included as an addendum are descriptions of United
   Heckathorn Co., Richmond, California,  added  to the final NPL  on March 14, 1990
   (55 FR 9688) , and descriptions of 10 sites being  dropped from the proposed NPL
   at this time.

       The size of the site is generally indicated,  based on information
   available at the time the site was scored using the Hazard Ranking System.
   The size may change as additional information is  gathered on  the sources and
   extent of contamination.

       Sites are arranged alphabetically by State  (two-letter abbreviations) and
   by site name.

                         Remedial Actions Under Superfund

       The Superfund program is authorized by  the Comprehensive Environmental
   Response, Compensation, and Liability Act (CERCLA) , enacted on December 11,
   1980, and the Superfund Amendments and Reauthorization Act  (SARA) , enacted on
   October 17, 1986.  Under SARA, the Hazardous Substances Superfund pays the
   costs not assumed by responsible parties for cleaning up hazardous waste sites
   or emergencies that threaten public health,  welfare, or the environment.  The
   Superfund program is managed by the U.S.  Environmental Protection Agency
   (EPA) .

       Two types of responses may be taken when a hazardous substance  is
   released (or threatens to be released) into  the environment:

       o Removal actions, emergency-type responses  to imminent  threats.  SARA
         limits these actions to 1 year and/or $2 million, with a waiver possible
         if the actions are consistent with remedial actions.   Removal  actions
         can be undertaken by the private parties responsible for the releases or
         by the Federal Government using the Superfund.

                  responses, actions intended  to provide permanent solutions at
         uncontrolled hazardous waste sites.  Rempdial responses are generally
         longer-term and more expensive than removals.  A Superfund remedial
         response can be taken only if a  site is on the NPL.  After publishing
         two preliminary lists and proposing a  formal list, EPA published the
         first NPL in September 1983 .   The list must be updated at least
         annually.

-------
     The money for conducting a remedial response or removal action at a
hazardous waste site can come from several sources:

     o The individuals or companies responsible for the problems
       can clean up voluntarily with EPA or State supervision.

     o The responsible party or parties can be forced to clean up
       by Federal or State legal action.

     o A State or local government can choose to assume the
       responsibility to clean up without Federal dollars.

     o Superfund can pay for the cleanup, then seek to recover
       the costs from the responsible party or parties. %

     A remedial response financed by Superfund is an orderly process that
generally involves the following steps:

     o Take any measures needed to stabilize conditions, which
       might involve, for example, fencing the site or removing
       above-ground drums or bulk tanks.

     o Undertake initial planning activities to scope out a
       strategy for collecting information and analyzing
       alternative cleanup approaches.

     o Conduct a remedial investigation to characterize the type
       and extent of contamination at the site and to assess the risks
       posed by that contamination.

     o Conduct a feasibility study to analyze various cleanup
       alternatives.  The feasibility study is often conducted
       concurrently with the remedial investigation as one project.
       Typically, the two together take from 18 to 24
       months to complete and cost approximately $1.3 million.

     o Select the cleanup alternative, after a period of public comment, that:

        — Protects human health and the environment

        — Complies with Federal and State requirements that are
           applicable or relevant and appropriate

        — Is "cost effective""— that is, affords results proportional to
           the costs of the remedy.

-------
        — Uses permanent solutions and alternative treatment technologies or
           resource recovery technology to the maximum extent practicable.

     o Design the remedy.  Typically,  the design phase takes  6 to 12
       months to complete and costs approximately  $1.5 million.

     o Implement the remedy, which might involve,  for example,
       constructing facilities to treat ground water  or removing
       contaminants to a safe disposal area away from the site.
       EPA expects the implementation (remedial  action)  phase to
       average out at about $25 million (plus any  costs to operate and
       maintain the action) per site and to take 6 to 12 months.

     The State government can participate in a remedial response under
Superfund in one of two ways:

     o The State can take the lead role under a  cooperative
       agreement, which is much like a grant in  that  Federal
       dollars are transferred to the State.  The  State then
       develops a workplan, schedule,  and budget,  contracts for
       any services it needs, and is responsible for  making sure
       that all the conditions in the cooperative  agreement are
       met.  In contrast to a grant, EPA continues to be
       substantially involved and monitors the State's progress
       throughout the project.

     o EPA can take the lead under a Superfund State  Contract,
       with the State having an advisory role.  EPA,  generally
       using contractor support, manages work early in the
       planning process.  In the later design and  implementation
       phases, contractors do the work under the supervision  of  the
       U.S. Army Corps of Engineers.  Under both arrangements, the
       State must share in the cost of the implementation phase  of
       cleanup.

                                ARCTIC SURPLUS
                               Fairbanks, Alaska

     Conditions at listing (October 1989):  The Arctic Surplus Site covers 22
acres in the southeast part of Fairbanks, Alaska.  The site is bounded to  the
north by a residential subdivision, to the south by the Alaska Railroad, to
the west by Fort Wainwright, and to the east by low-density residential
property.  Qn-site are a variety of buildings, storage trailers, and discarded
military equipment.

     Salvage operations at the site were conducted from 1946 to 1976 by a
number of parties, including the Department of Defense.  Approximately 3,500
to 4,000 drums are visible on-site.  They contain unknown quantities of
various oils, fuels, and chemicals; many drums are leaking.  Other wastes  on-
site include unknown quantities of asbestos rolls, batteries and battery acid
that was drained onto the ground during battery recycling activities, and  ash
piles from incineration of transformer casings.

     In September 1988, contractors for the Alaska Department of Environmental
Conservation conducted a site inspection and detected significantly elevated
levels of lead, zinc, PCBs, phenanthrene, pyrene, and copper in on-site soils.
Ground water beneath the site is shallow and contains elevated levels of lead
and zinc.  Over 12,000 people obtain drinking water from wells within 3 miles
of the site.

     In May and June 1989, EPA emergency staff assessed the site to determine
if a removal action was warranted.  A drum inventory showed approximately
1,700 drums contained liquids or sludges, some flammable or corrosive.
Cnlordane, a very toxic pesticide, was detected in soils at concentrations as
high as 320,000 parts per million.

     EPA started a removal action in September 1989 to stabilize the site  and
to prevent unauthorized access.  Leaking drums were overpacked, loose asbestos
was stabilized, and a chainlink fence was erected.  Additional activities  are
anticipated for the spring and summer of 1990.

     Status (May 1990);  On April 17, 1990 EPA issued a CERCLA Consent Order
to the Department of Defense (DOD) to complete the necessary removal
activities at the site.  A second consent order with DOD, issued on June 21,
1990, calls for a removal action to address all surface and containerized
contaminants.  The work is scheduled to be completed in two phases, from July
31 through October 15, 1990 and from June 1991 through completion.

                            EIMENDCRF AIR FORCE BASE
                     Greater Anchorage Area Borough, Alaska

     Conditions  at listing (July  1989);   Elmendorf Air Force Base covers
13,100 acres in  the  Greater Anchorage Area Borough immediately north of
Anchorage, Alaska.   The base is bounded to the west by Khik Arm of the  Cook
Inlet, and to the east by Fort Richardson Army Base.   Ship Creek flows  along
the southern perimeter.   In operation since 1940,  this base now hosts the  21st
Tactical Fighter Wing.

     Elmendorf is participating in  the  Installation Restoration Program (IRP),
established  in 1978.  Under this  program,  the Department of Defense seeks  to
identify, investigate, and clean  up contamination from hazardous materials.
As part of IRP studies, the Air Force identified 12 areas  where hazardous
materials had been generated,  stored, used,  or disposed of.  All require
further investigation.

     Initially,  the  Air Force focused on  five areas.   In the past, landfills
D-5 (now closed)  and D-7  (still active) received a variety of  hazardous
wastes, including lead acid batteries and waste  solvents.   The landfills,
unlined and  unbermed,  are in sandy  and  gravelly  soils. Shop wastes, including
solvents and paint thinners, were disposed of in a naturally occurring  unlined
trench designated as Site D-17.  Site IS-1 is where fuel in Building 42-400
spilled into floor drains that fed  into gravel-bottom dry  wells.  The last of
the five areas included in the initial  investigation  is Site SP5, where
approximately 60,000 gallons of aviation  fuel JP-4 spilled, of which only
33,000 gallons were  recovered.

     During  IRP  activities in 1983-87,  trichloroethylene,  tetrachloroethylene,
1,1,2,2-tetrachloroethylene, trans-l,2-dichloroethylene, 1,1-dichloroetnane,
1,1,1-trichloroethane, and lead were detected in on-site monitoring wells. An
estimated 121,000 Elmendorf employees and residents of Anchorage obtain
drinking water from  a  blended water system that  draws primarily from surface
water but also uses  wells within  3  miles  of hazardous substances on the base
on a standby basis.

     EPA is  reviewing  the Air Force's workplan for a  remedial  investigation/
feasibility  study (RI/FS)  to determine  the type  and extent of  contamination at
the base and identify  alternatives  for remedial  action.  She final workplan is
expected to  be completed  in the fall of 1989.

     Status  (May 1990);   EPA, the Air Force, and the  Alaska Department  of
Environmental Conservation are negotiating an Interagency  Agreement  (IAG)
under CERCIA Section 120  that will  facilitate the RI/FS.   Ihe  IAG is expected
to be signed in  August 1990.  Ihe Air Force will submit RI/FS  workplans for
units specified  in the IAG under  an agreed upon  time  schedule.

                                PORT WAINWRIGHT
                      Fairbanks North Star Borough,  Alaska

     Conditions at listing  (July 1989);  Fort Wainwright,  in Fairbanks North
Star Borough near Fairbanks, Alaska, was established in 1947.   Its primary
mission is to train soldiers and test equipment in  arctic  conditions.
Industrial operations primarily involve maintenance of aircraft and vehicles.

     Fort Wainwright consists of a cantonment area  (4,473  acres) on the
eastern border of Fairbanks, a range complex (8,825 acres),  and two maneuver
areas (898,306 acres).  Among contaminated areas on the cantonment area is a
50-acre sanitary landfill that has received waste oil, waste fuel, spent
solvents, paint residues, and fuel tank sludge since the mid-1950s.  The
landfill is an unlined unbermed area that  is built  up higher than  the
surrounding terrain.  A second contaminated area is the proposed North Family
Housing Area, which is 3,500 feet from the landfill.  The  Army used the area
for storage of petroleum products, solvents, and other chemicals and for
disposal of power plant ash and slag, which contain heavy  metals such  as
chromium and mercury.

     Fort Wainwright is participating in the Installation  Restoration  Program
(IRP), established in 1978.  Under this program, the Department of Defense
seeks to identify, investigate, and clean  up contamination from hazardous
materials.  In 1985 and 1986, as part of IRP studies, lead and chromium were
detected in monitoring wells at the landfill; in 1987, chromium and
tetrahydrofuran were detected in monitoring wells at the proposed  housing
area, and chromium was detected in soil.   An estimated 11,000  people,
including the entire population at Fort Wainwright  (10,900 people), obtain
drinking water from wells within 3 miles of hazardous substances on the fort.

     The Qiena River is used for sport fishing within 3 miles  downstream.

     The Army is developing a workplan for a remedial investigation/
feasibility study (RI/FS) to determine the type and extent of  contamination at
the fort and identify alternatives for remedial action.  The workplan  is
expected to be completed in the fall of 1989.

     Status (May 1990);  EPA, the Army, and the Alaska Department  of
Environmental Conservation are in the preliminary stages of negotiating an
Interagency Agreement (IAG) under CERCTA Section 120 that  will facilitate the
RI/FS.  The IAG is expected to be signed in September 1990.  The Army  will
submit RI/FS workplans for units specified in the IAG under an agreed  upon
time schedule.

                  STANDARD STEEL & METAL SALVAGE YARD (USDOT)
                               Anchorage, Alaska

     Oonditions at  listing (July 1989);   The Standard Steel & Metal Salvage
Yard cavers 6.2 acres in a heavily  industrialized area of Anchorage, Alaska.
The Federal Railroad  Administration, part  of the U.S. Department of
Transportation (USDOT),  acquired the land in the 1920s.

     Since  1972,  the land has been  leased to several  different recyclers whose
activities  included reclamation of  PCB-contaminated electrical transformers,
processing  of various types of equipment and drums from  nearby military bases,
and salvaging of assorted batteries. In November 1982,  the land was leased to
Standard Steel & Metals,  which subsequently filed for bankruptcy,  although it
is still operating.

     In May 1987, EPA detected high levels  of lead and PCBs and lower levels
of tetrachloroethylene in on-site ground water.   Over 121,000 people obtain
drinking water from blended water systems that draw primarily from surface
water but also use wells within 3 miles  of  the site on a stand-by basis.

     In November 1985,  EPA detected low  levels of PCBs in sediment of nearby
Ship Creek,  which is used for sport fishing.

     Using  CERCLA emergency funds,  EPA has  conducted  removal actions at the
site during the summer seasons starting  in  1986.  EPA removed surface wastes
— including an estimated 8,500 batteries,  175 transformers, 1,100 drums,  3
bulk storage tanks,  assorted containers, and metal debris—and transported the
materials to EPA-regulated disposal facilities.   Work during the 1988 season
completed the removal action by securing the site in  preparation for long-
term cleanup.   EPA's 1988 activities included sealing the soil surface in the
most highly contaminated areas,  removing the remaining containers of hazardous
materials,  and reworking and strengthening  the security  fence.

     EPA plans to negotiate for further  cleanup  with  parties potentially
responsible for wastes associated with the  site.

     Status (May 1990):   EPA has completed  preliminary contacts with the State
and USDOT for this  site.   An Interagency Agreement under CERCLA Section 120
will be negotiated  to facilitate investigation and cleanup.

                               Montgomery, Alabama

      Conditions at listing (June 1988);   T.  H.  Agriculture & Nutrition Co.
 formerly distributed  pesticides from a plant on the Birmingham Highway on the
 west side  of  downtown Montgomery, Montgomery County, Alabama.  During the
 1970s  and  possibly late 1960s,  the company operated under the name
 Thompson-Hayward Chemical  Co.   The plant closed in 1980.  The company changed
 its name to T. H.  Agriculture  & Nutrition Co. in  1981.

      While the plant  was in operation, insecticides, herbicides,  and possibly
 other  chemical wastes were buried in pits and trenches covering about 1 acre
 of the plant's 11.6 acres.  In 1981,  the company  excavated about 2,900 cubic
 yards  of contaminated soils and wastes and transported them to a hazardous
 waste  facility regulated under Subtitle  C of the  Resource Conservation and
 Recovery Act.

      Lindane, which the plant  distributed, is present in wells on and off the
 site,  according to tests conducted by the State and others.   Montgomery's
 water  supply  division has  21 wells within 3  miles of the site.  The system
 serves an  estimated 250,000 people.

      Prior to Thompson-Hayward's ownership of the plant, a company that
 handled water treatment chemicals operated on the site.  In 1986, T. H.
 Agriculture sold the  plant site but  retained responsibility for site cleanup.
 Site ownership has changed frequently since  then.  Capitol City Insulation,
 Inc.,  now  occupies the site.

      Status (May 1990);  EPA conducted a search for parties potentially
 responsible for wastes associated with the site.   EPA has sent letters to the
 four parties  identified informing them of their potential liability.

                              Paragould, Arkansas

     Conditions at listing  (October 1989);  The Monroe Auto Equipment Co. Pit
covers 4 acres including a  1-acre disposal area on Finch Road in Paragould,
Greene County, Arkansas.  The area around the site is rural.

     In 1973, the company received temporary  approval from the Arkansas
Department of Pollution Control  to dispose of electoplating sludges into a pit
that had formerly been mined for sand and gravel.  During 1973-78, the company
buried approximately 15,400 cubic yards of sludge containing iron, nickel,
chromium, and zinc in the pit.   The sludges also  contained trichloroethylene
and 1,1,1-trichloroethane,  which were used as degreasers during the
electroplating process.

     On-site monitoring wells and a private drinking water well 300 feet
southeast (downgradient) of the  pit are contaminated with 1,1-dichloroethane
and 1,2-dichloroethylene, according to tests  conducted in 1987-88 by the
Arkansas Department of Health and a Monroe consultant.   The consultant also
found arsenic, nickel, and  lead  in the monitoring wells.  An estimated 2,100
people obtain drinking water from private wells within 3 miles of the site.

                              St. David, Arizona

     Conditions at listing (June 1986);  Apache Powder Co. manufactured
nitroglycerine-based explosives from 1922 to 1963 and ammonium nitrate from
1963 to the present at a 945-acre property near St. David, Cochise County,
Arizona.  Prior to 1971, all waste water was drained to on-site dry washes
that are tributaries to the San Pedro River.  Since that time, waste water has
been contained in unlined ponds ranging from 6 to 8 feet deep.  About  15 ponds
covering 10 acres are present on-site, of which 5 to 10 were in use at any one
time.  The waste water contains elevated levels of nitrate.  In 1982,  the
Arizona Department of Health Services (ADHS) found more than 60,000 parts per
million of nitrate-nitrogen in waste water.  Soil in the bottom of the dry
ponds also contained high levels of nitrate-nitrogen, as did ash  in a  burning
ground located in a dry wash.

     In 1980, EPA detected toxic heavy metals in one lagoon at levels  above
drinking water standards.  In 10 shallow wells believed to be downgradient of
Apache Powder, ADHS and the Southeastern Arizona Governments Organization
detected nitrate-nitrogen in excess of drinking water standards.  At one time,
8 of the 10 wells were used for drinking water.

     A deeper artesian aquifer is not contaminated to date, but there  may be
danger of contamination in the future.

     ADHS has also detected elevated nitrate levels in the San Pedro River,
which borders the plant.

     Status  (June 1988):  After this site was proposed in June 1986,
procedural and technical issues arose.  Hence, EPA re-evaluated the site and
changed its score on the Hazard Ranking System, which EPA uses to assess sites
for the NPL.  Consequently, EPA is reproposing this site to allow an
additional 60-day comment period.

     Status  (Mav 1990);  In the summer of 1988, EPA confirmed the presence of
nitrates in private wells and in the San Pedro River and also found elevated
levels of nitrates and heavy metals in pond sediments.

     EPA has  issued a Unilateral Administrative Order requiring Apache
Nitrogen Products (formerly Apache Powder Co.) to conduct a remedial
investio^tion/feasibility study  (RI/FS) to  determine the type and extent of
contamination at the site and identify alternatives for remedial  action.
Field work is underway.  The RI/FS is scheduled to be completed  in the spring
of 1992.

                               Glendale, Arizona

     Conditions at  listing  (July 19891;  Luke Air Force Base occupies 4,198
acres in Glendale,  Maricopa County, Arizona, 13 miles west of downtown
Ehoenix.  The base  is located within the Sonoran Desert and rests on a broad
alluvium-filled valley within the western portion of Phoenix Basin.
Industrial-type operations  started  in 1941 and were comparatively small until
1946.  After a period of  deactivation, the base resumed operations in 1951.
During the 1950s, larger  quantities of wastes were generated by the expanded
maintenance required for  the  new jet aircraft assigned to the base.

     Luke Air Force Base  is participating in the Installation Restoration
Program  (IRP), established  in 1978.  Under this program, the Department of
Defense seeks to identify,  investigate, and clean up contamination from
hazardous materials. IRP studies identified a number of potentially
contaminated areas, including five  where hazardous wastes were disposed of.

     At the Waste Treatment Annex  (Site No. 2), a small quantity of low-level
radioactive electron tubes, believed to be encased in concrete, was buried  in
a pit 12  feet deep  in 1956.

     the  Perimeter  Road Petroleum,  Oil, and Lubricants  (POL) Waste Application
Site  (Site No. 4) was used  during approximately 1951-70.  POL wastes were
spread on the dirt  road around the  runway at the western portion of the base.
The majority of the wastes  consisted of contaminated JP-4 fuel, with some
diesel fuel, waste  engine oils, and waste solvents.  Among the substances that
may have  been included  were methyl  ethyl ketone, trichloroethane,
trichloroethylene,  toluene, cresylic acid, o-dichlorobenzene, phenolic paint
strippers, acetone, and paint residues and thinners.

     The POL Waste  Disposal Trench Site (Site No. 5) was used during about
1970-72.  POL wastes were disposed of in numerous trenches approximately  1.5
feet deep and in a  shallow lagoon at the northeast comer of the site.

     The South Fire Department Training Area  (Site No.  6) was used during
1941-46,  and again  during approximately 1951-63.  POL wastes were poured  onto
old aircraft or  simulated aircraft in a cleared, bermed area and then set on
fire.

     The North Fire Department Training Area  (Site No.  7) was used during
approximately 1963-73.   The disposal  method was similar to Site No. 6.  In
November 1983, eight water supply wells on the base were sampled as part  of
IRP.  Analysis indicated that two of the wells had low levels of
1,2-dichloroethane and trans-l,2-dichloroethylene.  Soil near one of the  wells
contained 1,2-dichloroethane.  An estimated 10,400 people obtain drinking
water from base  and private wells within 3 miles  of hazardous substances  on
the base.

      Status (May 1990);  EPA, the State,  and the Air Force are negotiating an
Interagency Agreement under CERdA Section 120 to cover future activities at
the site.

                  ADVANCED MICRO DEVICES,  INC. (Building 915)
                             Sunnyvale, California

     Conditions at listing (June 1988):   The Advanced Micro Devices, Inc.
 (Building 915) Site covers 5.5 acres at 915 De Guigne Drive in Sunnyvale,
Santa Clara County, California.  The company manufactures seminductor/micro-
processor devices on the site.  Three NEL sites are nearby:  Advanced Micro
Devices, Inc., placed on the NPL in June, 1986; Signetics, Inc., proposed  in
October 1984; and TRW Microwave, Inc., proposed in June 1988.  The sites  are
owned and operated by semconductor/microprocessor manufacturers and have
contributed to a commingled plume of ground water contaminated with organic
solvents.

     Building 915 was constructed on former agricultural land in 1973.  At
that time, three underground acid neutralization tanks were installed to  the
north of the building.  The building's operations also involved underground
tanks for storage of waste organic solvents.  In 1981, the company identified
trichlorobenzene in wells near the building.  High levels of other solvents,
including trichloroethylene, were present in on-site soils.  According to the
California Regional Water Quality Control Board (CRWQCB), soil contamination
resulted from leaking tanks and spills during the handling of solvents.
Contamination from Building 915 has the potential to reach nearby deeper
ground water  (230-700 feet) that supplies municipal wells within 3 miles  and
provides drinking water to an estimated 201,000 people in Santa Clara,
Sunnyvale, and Mountain View.

     In January 1982, the company completed removal of three tanks and
approximately 5,600 yards of contaminated soil and transported the materials
to a hazardous waste facility regulated under Subtitle C of the Resource
Conservation and Recovery Act  (RCRA).  Since late 1982, Advanced Micro Devices
and Signetics have operated a system to pump out contaminated ground water,
treat it with activated carbon, and discharge the treated water to Calabasas
Creek and South San Francisco Bay.

     On June 21, 1984, CRWQCB issue a Cleanup and Abatement Order under the
California Water Code requiring Advanced Micro Devices, Signetics, and TRW
Microwave to develop a joint plan preventing further contaminant migration.

     Since October 1985, under CRWQCB supervision, Advanced Micro Devices has
been operating a system to pump out contaminated ground water, treat it by air
stripping, and discharge the treated water to Calabasfis Creek and South San
Francisco Bay.  In October 1986, the company submitted to CRWQCB a study  of
hydrogeological conditions and a plan for remedial action.

     This facility obtained Interim Status under Subtitle C of RCRA when  it
 filed a Notification of Hazardous Waste Activity and Part A of a permit
application to treat, store, or dispose of hazardous waste.  Later, it
withdrew its Part A and converted to generator-only status with EPA or State
approval.  Hence, it satisfies a component of EPA's NPL/RCRA policy.

     Status  (May 1990);  EPA and CRWQCB are reviewing a draft remedial
investigation report submitted by Advanced Micro Devices.  The facility now
uses about 80% of the treated ground water as process water before it is
discharged to the local sewage treatment system.

                         CRAZY HORSE SANITARY lANDFILL
                              Salinas, California

     Conditions at  listing (June 1988);  The Crazy Horse Sanitary  Landfill is
on Crazy Horse Canyon Road within the  southeastern portion of the  hilly region
in Salinas in northern Monterey  County,  California.   The 125-acre  site is
owned by the City of Salinas and operated by Salinas Disposal Services.   Prior
to 1950, the site operated as an open  burning dump.   Since 1950, it  has been a
sanitary landfill.   In 1977, it  received a permit  from  the California Regional
Water Quality Control Board (CFS^2CB) to  accept  residential,  commercial,  and
nonhazardous industrial  wastes.   Some  pesticide containers have been disposed
of at the  facility  after triple-rinsing  as required  by  California  law.  The
CRWQCB permit prohibits  accepting hazardous waste.   According to Firestone
Tire & Rubber Co.,  its plant in  Salinas  disposed of  large quantities of
"banbury"  wastes (which  include  rubber materials,  carbon black,  other fillers,
and oils)  and mixed solvents (mainly benzene and toluene)  at the site from the
early 1970s to about 1982.

     In February 1985, CRW2CB sampled  three downgradient residential wells.
They were  found to  be contaminated with  volatile organic chemicals,  including
benzene and toluene.   An estimated 6,200 people obtain  drinking water from
private wells within 3 miles of  the site.

     A consultant to the City of Salinas conducted an extensive ground water
investigation in March 1985 to determine if the site is a source of  the off-
site residential well contamination.   The consultant concluded that  the site
is one of  the sources.   However,  the analytical results suggested  that there
may be a secondary  source  on private property adjacent  to the landfill.
Following  the investigation, Salinas started to implement a system to clean up
contaminated ground water.

     In June 1987,  Salinas purchased the homes  with  contaminated wells and
bulldozed  them.  The city  also pumped  water from wells  in an attempt to
stabilize  the ground water contamination.

     Status  (May 1990):  In May  1989,  Salinas completed the ground water
system, which involves pumping contaminated ground water to the surface via 23
extraction wells, passing  it through a passive  air stripper,  and treating the
gases removed in the stripper with activated carbon  before they are  discharged
to the atmosphere.   Some treated water is injected into the subsurface and
some is used for dust control.   EPA continues to monitor the remedial work at
the site.

                            Kern County, California

     Conditions at listing (July 1989);  Edwards Air Force Base (EAFB)  is in
Kern, Los Angeles, and San Bernardino Counties, California, occupying
approximately 800 square miles in the western portion of the Mojave Desert.
The base has been in operation since 1933.  Its primary mission is  to conduct
research and development on new aircraft.

     EAFB is participating in the Installation Restoration Program  (IRP),
established in 1978.  Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination  from hazardous materials.
Under IRP, the Air Force has identified 21 waste areas at the  facility.

     The Main/South Base area, at the western edge of Rogers Dry lake,  is the
primary area for maintenance and refueling of aircraft.  On several occasions,
large amounts of fuel have been spilled in the area, and poor  disposal
practices have released organic solvents to the ground.  Also  in the  area are
an abandoned sanitary landfill containing pesticides and heavy metals,  an area
where electroplating wastes were dumped, and the industrial waste pond, which
contains sediments rich in heavy metals.

     Trichloroethylene, trans-l^-dichloroethylene, 1,2-dichloroethane,
tetrachloroethylene, and methylene chloride are present in ground water
underlying the Main/South Base area, according to  a 1987 IRP report.  EAFB's
13,800 employees obtain drinking water from wells  within 3 miles of the
Main/South Base area.

     There is no perennial surface water at EAFB.

     The Air Force has completed an initial assessment of the  base  and  is now
conducting a remedial investigation/feasibility study to determine  the  type
and extent of contamination and identify alternatives for remedial  action.

     Status (May 1990);  The Air Force  is reviewing previous studies  to
determine any additional data needed to fully characterize known waste  areas.

     EPA, the State, and the Air Force are negotiating an Interagency
Agreement under CERCXA Section 120 covering response activities at  the  base.

                               Livermore, California

      Conditions at listing (June 1988):   Hexcel Corp.  operates on a 22-acre
 site in Livermore, Alameda County,  California.  The company formulates and
 reacts plastic resins for coatings and adhesives and custcm-inpregnates
 fabrics for production of reinforced parts for the aerospace industry.  Two
 documented spills occurred at the site in 1983.  In the first, 600 gallons of
 AP-92  solvent,  which consists of methylene chloride, methyl ethyl ketone
 (NEK), acetone,  and isopropyl alcohol,  leaked from subsurface plumbing.  In
 the  second,  1,500 gallons of MEK were released when a  valve on a storage tank
 was  left open.

      In March 1983, after the first spill, the California Regional Water
 Quality Control Board (CRWQCB) issued a Cleanup and Abatement Order under the
 California Water Code charging Hexcel with improper waste management.   Under
 the  order, Hexcel was to investigate the  extent of contamination,  clean up
 soil and ground water,  and prevent future spills.;  Hexcel excavated the tank
 and  drilled a well to recover as much of  the solvent as possible.
 Approximately 500 gallons of the second spill were recovered, but the rest
 migrated to  the excavated tank area.  Consultants to Hexcel identified
 dimethyl formamide in on-site soil and monitoring wells and MEK and acetone in
 the  wells.   Monitoring continues to define the extent  of contamination. An
 estimated  50,000 people obtain drinking water and 2,800 acres of agricultural
 land are irrigated from wells within 3 miles of the site.

      This  facility obtained Interim Status under Subtitle C of the Resource
 Conservation and Recovery Act (RCRA) when it filed a Notification of Hazardous
 Waste Activity and Part A of a permit application to treat, store, or dispose
 of hazardous waste.  Later, it withdrew its Part A and converted to generator-

 EPA's NPL/RCRA policy.

      Status  (May 1990):   On May 16, 1990,  CRWQCB issued a Site Cleanup Order
 to Hexcel, which rescinds the March 1983  order.  Ihe new order calls for a
 remedial investigation/feasibility study  (RI/FS)  meeting CERdA requirements.
 Ihe  RI/FS will  determine the type and extent of contamination at the site and
 identify alternatives for remedial action.

                              Fresno, California

     Conditions at listing (October 1989):  Industrial Waste Processing (IWP)
occupies approximately 0.5 acre at 7140 North Harrison Street in Fresno,
Fresno County, California.  Ihe area is primarily residential, with some light
industrial commercial operations.  During 1957-81, IWP principally recycled
solvents and lead solder.  During 1977-83, IWP operated as a distributor for
Ashland Oil.  Since 1983, the site has been used solely for storage of
chemicals and equipment.

     During an inspection in June 1988, EPA observed piles of waste lead
solder flux and leaking asbestos bags stored on  bare ground, and glycols and
chlorinated solvents stored in open and leaking  drums.  EPA analysis of on-
site soil identified numerous compounds, including lead, trichloroethylene
(TCE), perchloroethylene  (PCE), dichloroethylene (DCE), 1,1,2,2-
tetrachloroethane (PCA), and 1,1,1-trichloroethane  (TCA).

     EPA has designated Fresno County Aquifer, which underlies the Fresno
area, a sole source aquifer under the Safe Drinking Water Act.   Three
municipal water systems have a total of 83 supply wells within 3 miles of IWP
that draw from the Fresno County Aquifer. ' As of November 1988,  at least
13 of these wells contained organic solvents, including TCE, PCE,  and DCE,
according to EPA tests.  In May 1988, Pinedale County Water District Well #3
was closed due to contamination by organic solvents.  The well,  which is the
closest municipal well to IWP (within 0.25 mile  directly downgradient), had
390 parts per billion, the highest concentration of TCE detected to date.  One
active well within 2,000 feet of IWP supplies water to the Nelson  Elementary
School.  Municipal supply wells within 3 miles of IWP are part of  a
distribution system that serves over 300,000 people in the Fresno  area.

     In August 1988, EPA used CERdA emergency funds to remove all surface
wastes at the site and the top 2 inches of soil. The materials  were
transported to a hazardous waste facility regulated under Subtitle C of the
Resource Conservation and Recovery Act.

     Status  (May 1990);  The California Department of Health Services (DHS)
has listed the site on the California State Bond Expenditure Plan.  In May
1990, DHS completed a sampling plan calling for  collecting on-site boring
samples and installing three monitoring wells upgradient of the  site and three
downgradient.  Work is scheduled to start in the fall of 1990.

                             Cupertino, California

     Conditions  at listing (June 1988):   Intersil,  Inc., and. Siemens
Components have  manufactured semiconductors for several  years on  two locations
near one another covering 15 acres in Cupertino,  Santa Clara County,
California.  The facilities are surrounded by residential,  industrial,  and
business areas.

     Investigations conducted  in 1982 as  part of the California Regional Water
Quality Control  Board's underground tank  leak detection  program found organic
solvents, including trichloroethylene,  1,1,1-trichloroethane,
tetrachloroethylene,  trichlorofluoroethane, and 1,1-dichloroethylene, in soils
on the site and  in ground water on and off the  site.   Contamination is
believed to have resulted from localized  spills and from leaking  underground
storage tanks, piping,  and other equipment involving the two companies. More
than 300,000 people obtain drinking water from  public  wells within  3 miles of
the site.

     Siemens and Intersil began remedial  investigations  at  the site in  1982
and 1983, respectively, under  State supervision.  The  underground storage
tanks were removed, and in 1983 a  system  was installed to extract gases from
soil; the system was  expanded  in 1985.

     In June 1986, the  California  Regional Water Quality Control  Board  issued
Waste Discharge  Requirements under the California Water  Code requiring  both
companies to determine  the extent  of contamination  in  ground water  and  soils.

     In July 1986, a  system was installed to pump contaminated ground water in
the uppermost aquifer to the surface and  treat  it.   Since April 1988, a pump
and treat system for  the two uppermost aquifers has been in full-scale
operation.  Intersil  stopped operations in 1988,  and all remaining  underground
equipment was removed.

     Status  (May 1990):  In February 1990, the  two  companies released draft
reports of remedial investigations/feasibility  studies for  the site and off-
site downgradient areas.  Interim  off-site remedial activities are  scheduled
to begin in June 1990.   Also in June 1990, the  State plans  to issue tentative
site cleanup requirements and  hear public comments  on  the proposed  remedial
action plan.

                             Liverraore, California

     Conditions at listing (July 1989):  Lawrence Livermore National
Laboratory  (LLNL) (Site 300) covers approximately 11 square miles north of
Corral Hollow Road near the City of Livermore, California, straddling the
Alameda/San Joaquin County line.  The area  is rural.  LLNL was  first  owned by
the Atomic Energy Commission.  It is now owned by the U.S. Department of
Energy (USDOE) and operated by the University of California.  The main LLNL
site, located 15 miles west of Site 300, was placed on the NFL  in July 1987.

     Site 300's primary mission since its inception in 1955 has been  to test
high explosives.  It has also operated a number of solid waste  landfills,
accepting waste from the LLNL main site, Site 300, and Lawrence Berkeley
Laboratory.  Land disposal ceased at Site 300 in November 1988.  Site 300  also
formerly maintained a number of waste lagoons and dry wells for disposal of
liquid wastes and waste waters.  The dry wells have been removed from service,
and .the lagoons have been replaced by two double-lined surface  impoundments.
The lagoons are scheduled to be capped in the summer of 1989.

     Tests conducted in 1983 by an LLNL contractor detected trichloroethylene
(TCE), trans-l,2-dichloroethylene, and tetrachloroethylene in on-site
monitoring wells.  Soil is also contaminated.  These chlorinated hydrocarbons
are found in the vicinity of Buildings 834, 830, and 817 and  Pit 5.   The
highest concentrations are of TCE near Building 834.  TCE is  used as  a cooling
and heating agent to test the stability of  various high explosive compounds
and is stored near Building 834 for distribution through aboveground  piping.
A leak was suspected as the source of soil  and ground water contamination.
Approximately 350 people obtain drinking water from wells within 3 miles of
Site 300, most of them on Site 300 itself.

     During 1983  and 1984, T.T.T. observed increases in tritium  concentrations in
shallow monitoring wells downgradient from  experimental and waste disposal
areas in the west firing area of Site 300.  The shallow aquifer is not a
present or potential source of drinking water.

     In 1989, EPA issued a corrective action order under Section 3008 (h) of
the Resource Conservation and Recovery Act  (RCRA).  The State has issued a
draft Cleanup and Abatement Order.  In the  summer of 1989, USDOE plans to
complete a feasibility study identifying alternatives for cleanup at  Site  300.

     Status  (May  1990);  LLNL has completed capping the lagoons.  LLNL is
appealing the RCRA order to EPA.  The State draft order is pending resolution
of the RCRA order.

                             Clear lake,  California

     Conditions at listing  (June  19881 ;  The Sulphur Bank Mercury (SEM) Mine
is on the east shore of the Oaks Arm of Clear Lake, Lake County, California.
The area was initially mined  for  sulfur during 1865-68.  Mercury ore was mined
by underground methods during 1899-1902 and 1915-18.  The majority of the
mercury ore was mined using open pit methods during 1922-47 and 1955-57.  The
mine, once one of the largest producers of mercury in California, has been
inactive since 1957 and is presently owned by Bradley Mining Co. (BMC) of San
Francisco.

     Approximately 120 acres  of tailings and an open, unlined mine pit  (called
the Herman Pit) are on the property.  The mine tailings extend into the Oaks
Arm of Clear Lake along 1,320 feet of shoreline.  The Herman Pit covers
approximately 23 acres and is 750 feet upgradient of the lake.  The pit is
filled with water to a depth  of 150 feet.

     The California Regional  Water Quality Control Board (CRWQCB) is
coordinating an ongoing investigation of SBM.  Department of Health Services,
Department of Fish and Game,  and  CRWQCB analyses indicate that mercury is
present in the tailings and in the biota and bottom sediments in the Oaks Arm
of Clear Lake. The levels of  mercury in fish from Clear Lake led the State to
issue an advisory on May 14,  1986 against consumption of the fish.  The lake
is a major recreational area.

     On March 13 , 1987 , CRWQCB informed BMC that the Herman Pit is regulated
under the Toxic Pits Cleanup  Act  (TPCA) .  Under the act, BMC is required to
submit a Hydrogeologic Assessment Report (HAR) .  The property owners are
conducting a waste characterization study of the site prior to submitting a
HAR to determine if the site  may be exempt from TPCA.

     On November 4, 1987, CRWQCB  awarded a contract for a pollution abatement
study of the Oaks Arm of Clear lake and the adjacent mine site.  The study is
scheduled to be completed in  early 1989.

     An estimated 4,700 people obtain drinking water from Clearlake Oaks Water
District wells about 1 mile from  the site.

     Status (May 1990) ;  The  property owners submitted their HAR to CRWQCB in
July 1988.  CRWQCB exempted the Herman Pit from TPCA in April 1990.

     CRWQCB1 s study of Clear  Lake was completed in late 1989.  It indicated
that the largest continued input  of mercury to Clear Lake is probably from
erosion of waste rock and tailings into the lake.

                               Tracy, California

     Conditions at listing  (July 1989);  The Tracy Defense Depot  cavers 448
acres 1.5 miles southwest of Tracy, San Joaquin County, California.  The area
around the depot is primarily grassland and agricultural.  The site was an
Army Supply Depot from when it was activated in 1942.  In 1963 it was turned
over to the Defense Logistics Agency.  Special operations include repacking
leaking chemical containers, fumigation of shipping materials, vehicle
maintenance, painting, storage of chemicals, derusting and preserving of metal
parts, operation of chemical and photographic laboratories, storage and mixing
of pesticides, and storage  and treatment of liquid and solid wastes.

     Liquid waste treatment/storage areas  include two unlined  sewage effluent
ponds, two abandoned sewage lagoons, two lined industrial waste water ponds,
an abandoned paint spraying/stripping rinse water pond, an abandoned trench
where 150 drums of lubricating oil reportedly were buried, an  unlined pond for
holding storm water, an abandoned pesticide disposal trench, an abandoned area
where substantial amounts of formaldehyde  were buried, and aboveground and
belowground waste tanks.  Also, liquid wastes were formerly stored on-site in
an unpaved area, and solvents, radiological commodities, medical  supplies, and
solid and liquid chemicals  were disposed of in three burning pits.

     Former solid waste treatment/storage  areas include a fill area where food
items were buried, a fill area where construction material was buried, and
three impoundments where wastes containing mercury phosphate compounds were
stored.  Currently, all solid hazardous waste is hauled off-site  to facilities
regulated under Subtitle C  of the Resource Conservation and Recovery Act.

     Tracy Defense Depot is participating  in the Installation  Restoration
Program  (IRP), established  in 1978.  Under this program, the Department of
Defense seeks to identify,  investigate, and clean up contamination from
hazardous materials.   In 1985, IRP tests indicated the shallow aquifer below
the site, which extends from 15 feet to 250 feet below the surface, is
contaminated with trichloroethylene and tetrachloroethylene.   The water in the
aquifer, however, is generally too saline  for most uses.  Municipal, private,
and irrigation wells are within 3 miles of hazardous substances at the depot.
Water from Tracy's municipal well, which is within 3 miles of  the site, is
blended with water from other wells and from Delta Mendota Canal  to provide
drinking water to an estimated 28,600 people.

     The Defense Logistics  Agency is conducting a remedial investigation/
feasibility study (RI/FS) to determine the type and extent of  contamination  at
the depot and identify alternatives for remedial action.  The  State is review-
ing the depot's proposal to undertake an interim remedial measure involving
pumping and treating ground water to remove contamination.

     Status (May 1990);  A  public meeting  was held in May 1990 on the plan to
pump and treat contaminated ground water.  The State is reviewing the depot's
draft RI/FS plan.

     EPA, the State, and the Defense Logistics Agency will negotiate an
Interagency Agreement  under CERCLA Section 120 covering response  activities  at
the depot.

  since 1965 on a 3-acre site in Sootts Valley, Santa Cruz County, California.
  The California Regional Water  Quality Control Board (CRW2CB) and Watkins-
  Johnson's consultant have detected organic chemicals, including
  trichloroethylene, trichloroethane, tetrachloroethylene, dichloroethylene, and
  Freon in soil and ground water on the site.  The contamination is apparently
  the result of improper handling of hazardous waste.

       Early in July 1986, CRW2CB issued Waste Discharge Requirements to the
  company.  The requirements are the CFWQCB's legal mechanism for regulating
  activities at facilities under its jurisdiction.  Later in July, CRWQCB issued
  a Cleanup and Abatement Order  to the company.  In response, Watkins-Johnson

operated a 90-acre rail  yard  from approximately  1920 to 1983  at a location
2 miles south of Oroville, Butte  County,  California.  Union Pacific Co.
purchased the facility in January 1983.   On the  facility was  a wooden
structure encompassing approximately 3 acres,  known as  the round house,  which
was used to fuel, repair, service, and clean railcars.   Specific activities
conducted at the roundhouse include sandblasting, welding,  cutting,  and
fabricating.  As a result of  these activities, waste solvents,  oils, grease,
and waste waters containing heavy metals were  discharged to an unlined surface
impoundment until October 1987.

     In October 1985,  the California Department  of  Health  Services (CDHS)
detected arsenic, barium, copper, nickel,  and  chromium  in  soil and sludge in
the impoundment.  Chromium was also detected in  a monitoring  well adjacent to
the impoundment.  In addition, a  consultant to CDHS found  benzene and toluene
in soil and sludge in  the inpoundment in August  and October 1987.

     The California  Regional  Water Quality Control  Board (CRWQCB)  is
investigating the site.  According to CRWQCB,  ground water occurs at 30 feet
and is  connected to  deeper ground water  that is  a source of drinking water;
soils are permeable.   These conditions facilitate movement of contaminants
into ground water.

     Four California Water Service Co. wells are within 3  miles of the site.
Water from the  wells is  blended with water from  Feather River to serve the
company's 10,000 customers.   One  of the  wells  is on the site  and is leased
from Western Pacific.  Between 1984 and  1986,  California Water Service
detected dichloroethylene in  the  well.

     Feather River is  1  mile  from the site in  the direction surface water
drains.  The river is  used for recreational activities.

     In January 1989,  CRWQCB  issued a Cleanup  and Abatement Order to Union
Pacific and Salano Railcar, which has leased 5 acres of the site from Union
Pacific since 1970.  Work underway includes sampling of abandoned water supply
wells to determine the best way to seal  them,  installation of a water
separator to collect run-off  from locomotives, and  installation of equipment
to prevent run-off.

     Status (May 1990);  Under the Cleanup and Abatement Order, Union Pacific
has removed the soils  and sludges associated with the surface impoundment,
closed  two 30-gallon concrete sumps, removed an  underground tank,  closed an
underground oil/water  separator,  and replaced  the separator with an
aboveground unit.  Studies are underway  to characterize contaminated soils in
the fueling area and adjacent to  the old separator.

     Conditions at listing  (June  1988);   Chemical  Sales Co.  is a family-owned
chemical distribution business located at 4661 Monaco Street in an industrial
area of Denver, Denver County,  Colorado!   The company has operated on the 10-
acre property  since 1977.

     The chemicals handled  include ketones,  alcohols,  aliphatic compounds, and
chlorinated hydrocarbons such  as  tetrachloroethylene,  1,1,1-trichloroethane,
and methylene  chloride.  Some  chemicals are  purchased in bulk and stored in
tanks from which they are transferred to  drums or  other containers for sale.
In August  1985, the company reported  a spill of chlorinated solvents to the
Colorado Department of Health.  Another spill of water and hydrocarbons was
reported in April  1986.
   ' ; ;•)?>•• .   •
  "••  EPA tests conducted in late  1986 detected trichloroethylene,

                      CHESHIRE GROUND WATER (X3NTAMINATION
                              Cheshire,  Connecticut

     Conditions at listing (June 1988);   The Cheshire Ground Water
Contamination Site is on West Johnson Avenue in Cheshire, New Haven County,
Connecticut.  The site was originally proposed as "Cheshire Associates
Property".   Investigations subsequent to proposal indicate that ground water
contamination in the area cannot be attributed solely to the Cheshire
Associates property.  Ihe site is now considered a plume of contaminated
ground water from an unknown source.

     According to the Connecticut Department of Environmental Protection
(CT DEP), Cheshire Associates, a New York-based partnership, has owned the 15-
acre property at 604 West Johnson Avenue since 1966.  Over the years, the
property has been leased to a variety of tenants, including Valley National
Corp. (1966-79) and Cheshire Molding Co. (1979-80).  Both companies
manufactured plastic molding; neither kept records of disposal practices or
waste quantities.  Airpax Corp. Plant 2, the current lessee, has occupied the
premises since 1983.  The company manufactures electrochemical and electronic
devices, disposing of its wastes on-site in accordance with State regulations.
Cheshire Associates has never occupied the premises.

     In 1980, General Electric Co., a prospective buyer of the Cheshire
Associates property, determined that soil and ground water were contaminated
by hydrocarbons, that ground water was unsuitable for drinking, and that
drinking water supplies near the site were endangered.

     In 1983, CT DEP signed a Consent Agreement with Cheshire Associates
requiring the company to remove contaminated soil on its property and to
monitor eight volatile organic compounds in two private wells semiannually for
5 years.  In October 1983, Cheshire removed 20 cubic yards of contaminated
soil to an EPA-regulated landfill.  Recent semiannual sampling indicates low
concentrations of 1,1,1-trichloroethylene, 1,1-dichloroethylene, trans-1,2-
dichloroethylene, benzene, zylenes, and tetrachloroethylene in the private
wells.

     In June 1985, EPA found low concentrations of 1,1,1-trichloroethane, 1,1-
dichloroethylene, and  1,1-dichloroethane in shallow wells on the Cheshire
Associates Property and in a bedrock well at 657 West Johnson Avenue, which
has been taken out of  service.  Approximately 160 people within 1 mile of the
site use private wells.  Cheshire municipal wells serving 22,900 people are
2.1 miles southeast of the site.

     Status  (May  1990); EPA is planning to conduct a remedial
investigation/feasibility study to determine the type and extent of
contamination at the site and identify alternatives for remedial action.

                           NEW LONDON SUBMARINE  BASE
                             New London,  Connecticut

     Conditions  at listing (October 1989):   The  New London Submarine Base
covers 1,412 acres on the east bank of the Thames River,  New London, New
London County, Connecticut.   The  area around the base is mixed industrial,
commercial, and  residential  property.  Established in 1916, the base serves
primarily as an  operation and support base for submarine activities in the
Atlantic Ocean.

     The base is participating in the Installation Restoration Program (IRP),
established in 1978.   Under  this  program,  the Department of Defense seeks to
identify, investigate, and clean  up contamination from hazardous materials.
Under IRP, the Navy has  identified  16 potential  hazardous waste disposal areas
and has extensively studied  three areas.

     From 1957 to 1973,  volatile  organic compounds, pesticides,  PCBs, spent
battery acids, and other waste were buried below the water table in the 25-
acre Area A Landfill,  located on  base wetlands.   The second area currently
being investigated is the Defense Property Disposal Operations area, which was
used as a burning ground and landfill from 1950  to 1969.   The third area is
the Over Bank Disposal Area, which  operated from 1957 to the 1970s.

     According to Navy tests conducted in  1984,  sediment and surface water in
and around Area  A are contaminated  with lead, cadmium, 4,4-DDD,  and 4,4-DDT.
Ground water in  some  areas is as  shallow as 10 feet below the surface, and
soils are permeable.   These  conditions potentially threaten ground water,
which provides drinking  water to  3,500 to  5,000  people within 3 miles of the
base.

     Status  (May 1990):   EPA plans  to negotiate  an Interagency Agreement with
the Navy under CERdA Section 120 to cover the remedial activities to be
conducted.

                               Cheswold, Delaware

      Conditions at listing (January 1987);  Chem-Solv, Inc., started a small
 solvent distillation facility in 1982 on  1.5 acres  in Cheswold,  Rent County,
 Delaware.  Ihe company recycled waste solvents by placing a drum on an
 electric coil heater, which distilled the solvents  into a second drum.  The
 contents of the second drum were filtered into a third drum, which was
 returned to the customer.  Ihe residues remaining after distillation were
 classified as hazardous waste under Subtitle C of the Resource Conservation
 and Recovery Act (RCRA) and were stored on-site.

      On September 7, 1984, an explosion and fire destroyed  the distillation
 facility.  At the time, witnesses observed fluids flowing off a  concrete pad
 into the soil.  On September 21, 1984 and January 31, 1985, the  Delaware
 Department of Natural Resources and Environmental Control (DDNRBC) ordered the
 company under State law to cease operations immediately, monitor ground water,
 and remove all contaminated soil.  The company took no action.

      DDNREC conducted studies to characterize the upper Columbia Aquifer
 adjacent to the site.  DDNREC detected high concentrations  of organic
 chemicals, including trichloroethylene, 1,1,1-tridiloroethane, and
 1,1-dichloroethane, in on-site soils and ground water on- and off-site.  Both
 upper and  lower zones of the Columbia Aquifer are contaminated.  About
 5,500 residents are served by private wells within  3 miles  of the site.

      In September 1985, DDNREC excavated contaminated soil  and began using a
 process that passes air through the soil to remove volatile organic compounds.
 The air-stripping process reduced contamination to  levels that permitted
 returning the soil to the excavated area.  In December 1985, DDNREC started to
 recover and treat the volatile organics in the upper Columbia Aquifer.

      DDNREC has filed suit against Chem-Solv to recover the money it has
 spent.  The company has declared itself financially insolvent.

      When Chem-Solv started operations, it filed Part A of  a RCRA permit
 application, giving the company Interim Status as a storage facility.  In
 August 1985, DDNREC made a final decision to deny the storage permit.

      Because Chem-Solv, Inc., has lost Interim Status  (and  hence authorization
 to operate) and there are additional indications that the owner  or operator
 will be unwilling to undertake corrective action, the company meets a
 component of EPA's NPI/RCRA policy.

      Status (June 1988);   After this site was proposed, procedural issues
 arose and new technical information became available.  Hence, EPA reproposed
 the site.

      Status (May 19901;  In September 1988, EPA and 21 parties potentially
 responsible for wastes associated with the site signed an Administrative Order
 on Consent under CERCIA Section 106(a).  The order  called for a  remedial
 investigation/feasibility study (RI/FS) to determine the type and extent of
 contamination at the site and identify alternatives for remedial action.   A
 draft RI report is due in July 1990.

                               Houston,  Delaware

     Conditions at listing (June 1988);   The Rent County (Houston)  Landfill
covers 70 acres on County Road 397 in the Brown's Branch Watershed,  2.1 miles
north of  Houston,  Kent County, Delaware.  The watershed feeds to McCauley
Pond, Murder Kill  River (Cripple Swamp), and the Delaware Bay.

     The  landfill,  operated during 1969-80 by the county,  accepted wastes from
Harrington,  Dover,  and other locations.   Among  the materials were  residential
trash, pesticides,  sludges  from  poultry processing plants, oil  sludges,
hospital  wastes, waste polymers,  and solvents.   In all,  the landfill holds an
estimated 2  million cubic yards  of waste and fill materials.  The  wastes were
deposited in trenches excavated  between 10 and  25 feet.   The landfill had no
liner or  leachate  collection system.  In 1980,  the county covered  the landfill
with 3 to 5  feet of very sandy soil and planted grass and other vegetation.
The property is owned by the State.

     Organic and inorganic  contaminants, including 4-methyl-2-pentanone,
4-methylphenol, chromium, arsenic,  and manganese, are present in a monitoring
well, according to EPA's December 1985  site inspection.   The well  is in the
water-table  aquifer underlying the site that supplies private drinking water
wells in  the area.  Private wells within 3 miles of the site serve
approximately 1,300 people; the  nearest well is 1,700 feet from the monitoring
well.  The tests found no contamination of private wells.   Cropland within
3 miles of the site is irrigated by wells.

     During  a May  1986 inspection,  EPA  observed leachate seeping from the
landfill.  The leachate contained elevated levels of  4-methylphenol, arsenic,
chromium, lead, zinc,  and mercury,  threatening  nearby surface waters,  which
are used  for recreational activities.

     The  site is only partially  fenced,  permitting people and animals to come
into direct  contact with the leachate.

     Status  (May 1990);   EPA is  conducting a search for parties potentially
responsible  for wastes associated with the site.   EPA will then investigate
the possibility of those identified in the search performing a  remedial
investigation/feasibility study  to determine the type and extent of
contamination at the  site and identify alternatives for remedial action.

                               Newport, Delaware

     Conditions at listing (October 1989):  Koppers Co., Inc.,  operated a wood
preserving plant from 1940 to 1971 on a 317-acre site at the corner of Water
Street and Jones Street in Newport, New Castle County,  Delaware.   The site  is
bounded by rivers, creeks, and the Newport plant of E.I. Du Pont  De Nemours &
Co., Inc.

     In 1971, Koppers sold the site to Dupont.  As part of the  sales
agreement, Koppers removed chemicals in the process tanks.  Dupont removed  all
structures from the site, which is now vacant.

     The treatment process Koppers used consisted of loading railroad ties  and
telephone poles into cylinders and pressure injecting them with creosote or a
mixture of no. 2 fuel oil and pentachlorophenol.  In the treatment area were a
pond filled with water used for fire protection and a sump where  any effluent
from the treatment process was collected.

     In December 1984, EPA detected polynuclear aromatic hydrocarbons such  as
benzo(a) anthracene, pyrene, fluoranthene, chrysene, and benzo(a)pyrene, in  on-
site soil, pond sediments, and nearby creek sediments.   These compounds are
constituents of creosote.

     Ground water is the most important source of drinking water  in the area.
The Artesian Water Co. draws drinking water from three  wells within 3 miles of
the site and blends it with other water to serve its 150,000 customers. The
wells tap the lower Potomac Formation, which consists of permeable deposits
and is hydraulically connected to the overlying Columbia Formation, permitting
water to move between them.

     Wetlands are present both on the site and bordering the site.

     Status  (May 1990);  EPA has  notified parties potentially responsible for
wastes associated with the site of their potential liabilities.  EPA is

                            Mount Pleasant,  Delaware

     Conditions at listing (June  1988):  The Sealand T.imi-ha^ site occupies
approximately 2 acres in Mount Pleasant, New Castle County, Delaware.  The
area is primarily agricultural and residential.  Operations began in 1971 when
Adams Laboratory rented the property  from Conrail,  Inc., to operate a
rendering plant.  In 1979,  Conrail reportedly cleaned up the property after
Adams Laboratory abandoned the rendering plant.  The property remained vacant
until September 1982,  when Steve  and  Wayne  Hawkins  rented  it from Conrail.
From then until August 1983, they operated  a creosote manufacturing plant
under the names Sealand T.-iwitmH and Oil Industry.   In addition, the facility
accepted coal tar, gas tar, and ink oil wastes, allegedly  to be recycled.
Instead, they were stored  on-site in  tanks  and drums.  When the Hawkinses
abandoned the facility in  1983, it contained 22 storage tanks,  a boiler  house,
mixing chambers, pressure  vessels,  several  hundred  55-gallon drums containing
assorted creosol intermediates, and a 10,000-gallon wooden storage tank.

     A 1983  investigation  by the  Delaware Department of Natural Resources and
Environmental Control (DDNKEC) revealed that the wooden tank and numerous
drums were leaking.   Analyses of  tanks, drums, and  soil on- and off-site
detected polynuclear aromatic compounds, creosols,  solvents, and other toxic
organic compounds.

     In December 1983, in  response to the imminent  threat  to human health, EPA
used CERdA  emergency funds to remove 240,800 gallons of coal tar, 320 drums,
and 80 cubic yards of solid waste.  The hazardous materials were transported
to a facility regulated under Subtitle C of the Resource Conservation and
Recovery Act.  EPA also cleaned the storage tanks and capped the site with a
layer of clay.

     Nickel  and acenaphthalene were present in an on-site  monitoring well in
EPA and DDNREC analyses conducted in  1984.   Soils on the site are permeable
and ground water shallow  (5 feet  in some cases), conditions that facilitate
movement of  contaminants into ground  water.  Private wells within 3 miles of
the site provide drinking  water to an estimated 135 people.

     Joy Run is adjacent to the site  and flows into the Chesapeake and
Delaware Canal, which is used for recreational activities.

     Status  (May 1990); Under an Administrative Order on  Consent effective  in
December 1988, 15 parties  potentially responsible for wastes associated  with
the site are conducting a  remedial investigation/feasibility study to
determine the type and extent of  contamination at the site and  identify
alternatives for remedial  action.  The work is scheduled to be  completed early
in 1991.  In January 1990, EPA completed an action  to recover funds spent on
the removal  action from potentially responsible parties.

Electronics Corp. Site consists of two areas located directly across from each
other on N.W. 76th Street in Miami,  Dade  County,  Florida.  The site is in an
industrialized area northeast of Miami International Airport.

     The Anaconda Aluminum portion of the site covers  approximately 1 acre at
3610 N.W. 76th Street.  Between May  1957  and February  1983, operations
involved an electrochemical process  using acids and an aluminum-containing
base to produce a protective coating on aluminum.   Up  to  1967,  a chromic acid
process was employed.  The Milgo Electronics portion of the site covers
approximately 0.5 acre at 3601 N.W.  76th  Street.   Between 1961 and June 1984,
operations involved chrome, nickel,  and copper electroplating of data
processing equipment and the manufacturing of cabinets for electronic
components.  Both companies disposed of liquid waste on-site.  Anaconda
Aluminum used soakage pits, while Milgo Electronics used  a drainfield.

     In April 1987, EPA found chromium and lead in the Biscayne Aquifer, which
EPA has designated as a sole source  aquifer under the  Safe Drinking Water Act.
At least four municipal well fields  are within 3  miles of the site: the Upper

     Conditions at listing (June  1988);   B & B Chemical Co.,  Inc.,  has
manufactured industrial  cleaning  compounds on a  2-acre site in a highly
industrialized area in Hialeah, Dade County,  Florida,  since 1958.  Die Miami
Canal is 800 feet to the southwest.

     The company  prepares its proprietary products in mixing vats.
Approximately once.a year the vats and tank trucks are washed down.  Before
1976, the waste water  was deposited  in unlined lagoons.  Since then,  it has
gone into a pretreatment system before being discharged into the Hialeah sewer
system.

     Since  about  1975, the Dade County Department of Environmental  Resource
Management  (DERM)  has  been concerned about the impact of  the lagoons  on ground
water in the vicinity.  In 1985,  EPA found solvents such  as chlorobenzene,
trans-l,2-dichloroethylene,  1,2-dichlorobenzene,  and 1,4-dichlorobenzene in
monitoring  wells  on and  off the site and chromium in on-site wells.  Wells in
the contaminated  area  have been taken out of service.

     In  1987,  a B & B  contractor  conducted a remedial investigation/
feasibility study (RI/FS)  to determine the type  and extent of contamination at
the site and identify  alternatives for remedial  action.

     The Biscayne Aquifer, which  EPA has designated as a  sole source  aquifer
under the Safe Drinking  Water Act, supplies drinking water for all  of Dade
County.  At the site,  a  layer of  quartz sand overlies the limestone aquifer;
both formations have very high horizontal and vertical permeabilities.   These
conditions  facilitate  movement of contaminants into ground water, as  well as
movement of contaminated ground water.   Four municipal well fields  — the John
E. Preston,  the Hialeah,  and the  Upper and lower Miami Springs — are within
3 miles  of  the site.   One well is within 3,000 feet of the site.  The four
well fields serve 750,000 people.

     Status (May  1990);   B & B installed an air  stripper  to remove  volatile
organic  compounds from ground water  but stopped  operating it in  early 1989
with approval of  DERM  or EPA.

     In  October 1989,  EPA determined that B & B's RI/FS was inadequate.   EPA
has requested access to  the site  to  complete the RI/FS.

at 1121 Silver Beach Road, lake Park, Palm Beach County, Florida.  Hie
facility began operation in October 1969 under the name Basic
Microelectronics, Inc.  In 1981, the site was sold to Textron,  Inc. , and began
operation under the name EMI-Textran.  Operations stopped in January 1986.

     The facility manufactured chrome-backed glass plates used  in producing
electronic components.  The process involved cutting, washing,  and polishing
glass plates before chrome was deposited.  Cyanide was used in  the glass-
etching process.  Liquid waste from the process was discharged  to percolation
ponds and drain fields under a 4-year industrial waste water treatment permit
issued on November 17, 1980, by the Florida Department of Environmental
Regulation  (PEER) . Four wells were  installed at  the facility to monitor  permit
compliance.  On November 10, 1983,  BMI-Textron received a Notice of Violation
from the Florida Department of Health and Rehabilitative Services for
excessive levels of nitrates and total dissolved solids, as well as pH below
the allowable limits.

     In August 1984, EMI submitted  data to FEER  showing cyanide contamination
of soil and ground water at the site.  On December 20, 1984, BMI-Textron and
FDER entered into a Consent Agreement requiring  the company to  remove
contaminated soils at the site and  to submit a detailed monitoring program for
determining the nature and extent of ground water contamination at the site.
BMI-Textron removed approximately 680 cubic yards of cyanide-contaminated  soil

                            HOMESTEAD AIR FORCE BASE
                               Homestead, Florida

     Conditions at  listing (July  1989);  Homestead Air Force Base  is in Dade
County, approximately 25 miles southwest of Miami and 7 miles east of
Homestead, Florida.   The facility encompasses 2,916 acres with additional
easements of 429  acres.  The area around the base is mostly agricultural and
residential.  The base has jurisdiction  over several remote annexes, but there
is little evidence  that hazardous substances have been disposed of at those
locations.

     The base was activated in September 1942 and initially was operated by
the Army Air Transport Command.   After extensive hurricane damage  in 1945, the
base was turned over to Dade County,  which used it for small commercial and
industrial operations.  In 1953,  the Air Force  acquired the base and rebuilt
it.

     Wastes have  been disposed of on-site  since the facility^ inception.  A
landfill was operated in the 1940s,  but  little  is known about this operation.
During Dade  County's ownership, electroplating  operations were conducted on
the site, and plating wastes containing  heavy metals and cyanides  were
allegedly disposed  of directly on the ground.

     After the Air  Force assumed  control in 1953, hazardous substances  were
disposed of  in Fire Training Area 3,  which was  unlined and had no  system to
collect residual  fluids, and the  Residual  Pesticide Disposal Area.  Several
spills also  occurred, including one  of PCBs from an electrical transformer.

     Homestead Air  Force Base is  participating  in the Installation Restoration
Program (IRP), established in 1978.   Under this program, the Department of
Defense seeks to  identify,  investigate,  and clean up contamination from
hazardous materials.  IRP  studies have detected high concentrations of  ethyl
ether in ground water throughout  and downgradient of Fire Training Area 3.
Approximately 5,500 gallons of ethyl ether were disposed of in the area in
January 1984.  The  Biscayne Aquifer,  which underlies the site, has been
designated as a sole source aquifer  under  the Safe Drinking Water  Act.   An
estimated 16,600  people obtain drinking  water from wells into the  aquifer
within 3 miles of the hazardous substances on the site.

     The base is  surrounded by a  perimeter canal, which discharges into
Military Canal and  ultimately into Biscayne Bay 2 miles to the west.

     The Air Force  plans further  investigations of releases of hazardous
substances and their migration under the IRP and a permit issued under
Subtitle C of the Resource Conservation  and Recovery Act and incorporating
corrective action.

     Status  (May  1990) t  EPA, the Florida  Department of Environmental
Regulation,  and the Air Force are negotiating an Interagency Agreement  under
CERCXA Section 120  to cover response activities at the base.

                                Madison,  Florida

     Conditions at listing (June 1988);  The Madison County Sanitary Landfill
covers approximately 133 acres northeast of the City of Madison, Madison
County, Florida.  The city owned and operated the landfill  from 1971 through
March 1980.  According to city records, ITT Thompson Industries, Inc.,
disposed of drums and waste containing trichloroethylene  (TCE)  and other
compounds at the landfill during this period.  The county purchased the
landfill from the city and has operated it since April  1980.  The  landfill  is
permitted by the State to accept municipal solid waste.

     In September 1984, the county found TCE in monitoring  wells at the
landfill.  In November 1984, the Florida Department  of  Environmental
Regulation (FDER) removed a number of drums from one location where ITT
Thompson's drums had been buried.  Drums were removed from  a  second area in
March 1985.  All materials were transported to a hazardous  waste  facility
regulated under Subtitle C of the Resource Conservation and Recovery Act.

     Beginning in January 1985, the county sampled numerous private wells in
the vicinity of the landfill.  High concentrations of TCE and 1,2-
dichloroethylene were found in three wells.  The county,  and  later ITT
Thompson, provided bottled water and ice to these families.  In addition, the
city, the county, and ITT Thompson installed water filter systems at these
homes.

     In February 1986, FDER entered into a Consent Agreement  with the city/
county, and ITT Thompson requiring them to investigate  ground water near the
site.  The consultant they hired found TCE, methylene chloride, and trans-1,2-
dichloroethylene in on-site monitoring wells and off-site private wells.

     Approximately 95 private wells and  3  City of Madison wells are within
3 miles of the site, threatening the drinking water  supplies  of an estimated
4,400 people.

                               Princeton, Florida

     Conditions at  listing (June 1988);  Wbodbury Chemical Co.  occupies
3 acres along the west  side of U.S. Route  1 in the southeast section of Dade
County approximately  0.5  mile  southwest  of Princeton, Florida.  Since  1975,
the company has blended technical-grade  materials in 50-gallon  vats to produce
pesticides and fertilizers.

     The site consists  of six  buildings, including an office, warehouses,  and
production buildings, as  well  as several aboveground storage tanks,  the
majority of which are diked.   Most of the  facility grounds is paved.   The
surrounding area is primarily  agricultural, with populations concentrated in
the small towns of  Princeton and Goulds.  Previously, the site  was  a toroato-
and potato-repacking  house and a labor camp for farm workers.

     In 1986, EPA identified aldrin,  dieldrin,  toxaphene, and chlordane in
four surficial soil samples from the  site  vicinity.

     The Biscayne Aquifer underlying  the site supplies  drinking water  to an
estimated 17,600 residents of  Dade County  within 3 miles  of  the site.   EPA has
designated the aquifer  under the Safe Drinking Water Act  as  the sole source of
drinking water for  Dade County.   A layer of quartz sand overlies  the oolite
limestone of the aquifer; both formations  are highly permeable, facilitating
the horizontal and  vertical movement  of  ground water, which  is  about 7 feet
below the surface.  Three well fields and  several private wells are within
3 miles of the site.  The well fields include the Elevated Tank Well Field
approximately 2.6 miles south  of the  site, the Naranja  Well  Field
approximately 1.5 miles to the southwest,  and the Homestead  Air Force  Base
Well Field approximately  2.5 miles south.   A  private well is 570  feet  from the
site.

     A canal owned  and  operated  by the State  is approximately 2,350 feet
northeast of the site.  It flows into Biscayne Bay.

     Status  (May 1990):  In January 1990,  Wbodbury Chemical  removed toxaphene-
contaminated soils  from the southeast corner  of the  site.  The  work was
performed under the direction  of EPA  and the  Dade County  Environmental
Resources Management.

     In March 1990, EPA issued a "special  notice letter"  offering Woodbury
Chemical the opportunity  to conduct a remedial investigation/feasibility study
 (RI/FS) to determine  the  type  and extent of contamination at the  site  and
identify alternatives for remedial action. EPA is reviewing Woodbury
Chemical's response.

     Conditions at listing  (January 1987):   The  Diamond Shamrock Corp.
Landfill covers less than 1 acre  in Cedartown, Polk County, Georgia.  Between
1972 and 1977, the company buried drummed and bulk waste in three 6-foot-deep
trenches.  The waste included  fungicides, amides,  oil and oil sludges, esters,
ethers, alcohols, and metallic salts,  according  to the company.  In 1986,  the
site was sold to Occidental Chemical Corp.

     The trenches are unlined, in an area of permeable soils, and in the
floodplain of Cedar Creek, which  is a  major tributary of the Coosa River.
Ground water is shallow (less  than  10  feet).  These conditions potentially
threaten surface water  and ground water in  the area.

      Conditions  at listing (June 1988);   Die Wbolfolk Chemical Works,  Inc.,
 Site covers  18 acres near the center of Fort Valley,  Peach County,  Georgia.
 The company  began  operation in 1910  as a lime-sulfur plant and has evolved
 into a full-line pesticide plant formulating pesticides in liquid,  dust,  and
 granular forms for the agricultural, lawn,  and garden markets. The methods of
 handling these products over the years have resulted in extensive
 contamination at the site. Tests conducted by the Georgia Environmental
 Protection Division in 1985 and 1986 detected  metals and pesticides, including
 lead,  arsenic, chlordane, DDT,  lindane,  and toxaphene,  in on-site soil and
 ground water,  and  in an open ditch south of the plant.

      Three of the  five Fort Valley municipal water supply wells are within
 1,000  feet of the  facility.  The system is the sole  source of water in the
 area.  Late  in 1986,  EPA found arsenic and lead in two  of the wells at levels
 below  Federal drinking water standards.   An estimated 10,000 people obtain
 drinking water from municipal wells  within 3 miles of the site.
                      >
      State records indicate numerous instances where untreated industrial
 waste  was  discharged into surface waters.  During a  routine inspection in
 1979,  EPA  discovered that the facility was discharging  unauthorized waste
 water  from the production of  the pesticide dichlorcbromopropane into Bay
 Creek.  Records  indicate that the majority of  the waste waters was discharged
 into a storm sewer on the site.   These effluents would  flow into  an open  ditch
 located south of the plant and then  into Big Indian  Creek.

      The company has changed  hands several times.  The  current owner,  Security
 Lawn and Garden  Products Co., acquired the operation in 1984 from Canadyne-
 Georgia Corp., which operated the facility during 1977-84. In 1986-87,
 Canadyne capped  one area of contamination and  removed some contaminated soil
 to a hazardous waste facility regulated under  Subtitle  C of the Resource
 Conservation and Recovery Act.

      Status  (May 1990);   On April 24,  1990,  EPA and  Canadyne-KSeorgia Corp.
 signed an  Administrative Order on Consent under which the company will conduct
 a remedial investigation/feasibility study (RI/FS) to determine the type  and
 extent of  contamination at the site  and identify alternatives for remedial
 action.  The company will shortly submit an RI/FS workplan to EPA for review.

                                 Oahu,  Hawaii

     Conditions at listing (July 1989);  Schofield Barracks, an installation
of the Amy Support Command, Hawaii, covers 17,725 acres in central Oahu,
Hawaii.  The area around the barracks is mostly rainforest; the closest
municipality is Wahiawa to the north.  The facility is divided into two areas:
East Range and the Main Post.  Schofield Barracks was established in 1908 to
provide a base for the Army's mobile defense of Pearl Harbor and the entire
island.  Industrial operations involve maintenance, repair, painting, and
degreasing, all using various organic solvents.

     In April 1985, the Hawaii Department of Health informed the Army that
high levels (30 parts per billion) of trichloroethylene  (TCE)  had been
detected in wells supplying drinking water to 25,000 people at Schofield
Barracks.  An'additional 55,000 people  in Wahiawa and Miliani  obtain drinking
water from public wells within 3 miles of hazardous substances on the base.

     An Army investigation in May 1985 confirmed TCE contamination of
on-base drinking water wells, and recommended short-, medium-, and long-term
measures.  In September 1986, the Army started operating an air stripping
facility to remove TCE from the contaminated Schofield Barracks wells, making
the water safe to drink.

     Within 3 miles downstream of the base, Wahiawa Reservoir  is used to
irrigate 3,000 acres of pineapple fields and is also used  for  recreational
activities.

     Schofield Barracks is participating in the Installation Restoration
Program, established in 1978.  Under this program, the Department of Defense
seeks to identify, investigate, and clean up contamination from hazardous
materials.

     Status (May 1990);  Schofield Barracks continues to treat contaminated
ground water at a rate of 3 to 6 million gallons per day.

     EPA plans to negotiate an Interagency Agreement with  the  Army under
CERCXA Section 120 to cover future activities at the site.

     Conditions at listing  (June 1988);  The E. I. du  Pont de Nemours & Co.,
Inc., Site consists of two areas off County Road X23 in a rural area of Lee
County approximately 3.5 miles  southeast of West Point,  Iowa.  In the early
1950s, Du Pont sent wastes from its  nearby Fort Madison paint plant to the two
areas, which are about 1.25 miles apart and cover about 4 acres.

     Du Pont estimates that  it  sent  12,000-18,000 55-gallon drums of waste
annually to the site.  Disposal occurred from  April  1949 to November 1953 at
the first area, now owned by a  private citizen, and  on a limited basis during
November 1952-November 1953  at  the second area, now  owned by Du Pont.  On both
areas, wastes were dumped into  shallow trenches  (each  reportedly 75-100 feet
long, 10-12 feet wide, and 3-4  feet  deep) and  periodically burned.  'The
trenches have since been filled and  the area graded.  Ravines are adjacent to
the two disposal areas on the north-northwest  sides.

     EPA investigations in April 1987  detected lead  in on-site wells.  An
estimated 1,200 people depend on private wells within  3 miles of the site as
their sole source of drinking water.  Two creeks approximately 1 mile from the
site are used for limited recreational activities.

     Status (May 1990);  Under  a Unilateral Administrative Order issued by

 occupies one city block in Fairfield, Jefferson County, Iowa.  It is bordered
 on the west by a residential area. Iowa Electric Light and Power Co. (TETP) has
 owned the  site since 1878.  This company was known as Interstate Power Co.
 from 1878  to 1917 and Iowa Electric Co. from 1917 to 1953, when it assumed its
 present  name.  During 1878-1950, the facility produced a commercial fuel
 substitute from coal.  Since 1950, the site has served as a maintenance
 garage.

      The main wastes associated with coal gasification are polynuclear
 aromatic hydrocarbons (PAHs) , which are found in coal tar, a by-product of
 gasification, and cyanide salts, which are found in iron oxide waste produced
 during purification of the manufactured gas.  Some of the coal tar was sold
 and  some was buried in on-site pits.  Disposal methods for the iron-cyanide
 waste are  not known,  but it may also have been dumped on-site.

      In  1985, TRT.P consultants detected PAHs, including benzene, phenanthrene,
 anthracene,  pyrene, and benzo(a)pyrene, in ground water near the site.  In
 1987, EPA  confirmed the contamination. TFTP conducted quarterly sampling to
 monitor  the spread of contamination.  An estimated 1,100 people obtain
 drinking water from private wells within 3 miles of the site.

      An  intermittent stream flowing from the site intersects Cedar Creek
 2.9  miles  downslope.   The creek is used for recreational activities.

     Conditions at listing  (June 1988):   The Fanners' Mutual Cooperative Site
covers approximately 6  acres in Hospers,  Sioux  County/ Iowa, along the east
side of the Floyd River.  The cooperative owns  the property and has operated
an agricultural supply  and  service business at  this location since 1908.  At
present, the cooperative stores bulk grain,  fertilizers,  and pesticides at the
site.

     In 1984, the Iowa  Department of Environmental Quality found 1,2-dichloro-
ethane, carbon tetrachloride  (a grain  fumigant),  and chloroform in two Hospers
municipal wells within  3 miles of the  site.   The wells, which served an
estimated 1,900 people,  have been closed.   The  city now draws water from
another well field.  In 1985, a consultant  to the cooperative found some of
the same chemicals in on-site soils and ground  water and in Floyd River
downstream  of the site.

     In August 1986, the State issued  an  Administrative Order requiring the
cooperative to conduct  a remedial investigation/feasibility study (RI/FS) to
determine the type and  extent of contamination  at the site and identify
alternatives for remedial action.  Partial  results were submitted to the State
in February 1987, and negotiations culminated in a Consent Order in June 1987.

     Conditions at listing (July 1989);  The Iowa Amy Ammunition Plant (IAAP)
covers 19,127 acres  in rural Des Moines  County near Middletown,  Iowa,
approximately 10 miles west of  Burlington.  lAAP's  primary mission since 1941
and intermittently to the  present has been  to  load, assemble, and pack a
variety of conventional  ammunitions and  fusing systems.  Ihe current operating
contractor is Mason  and  Hanger-Silas Mason  Oo.,  Inc.

    Wastes produced  at IAAP consist of various explosive-cxantaining  sludges,
waste water, and solids; lead-containing sludges; ashps  from incineration and
open burning of explosives; and waste solvent  from  industrial and laboratory
operations.  The explosives include trinitrotoluene (INT), dinitrotoluene
(DNT), and cyclcmethylenetoinitramine (RDX).   Past  operations generated waste
pesticides, radioactive  wastes  that have been  removed from the site, and
incendiaries.

    IAAP is participating  in the Installation  Restoration  Program (IRP).
Under this program,  established in 1978, the Department  of Defense seeks to
identify,  investigate, and clean up contamination from hazardous materials.
As part of IRP, the  Army has identified  a number of potentially  contaminated
areas, including a now-unused 4-acre settling  lagoon at  Line 800 (known as the
Line 800 Pink Water  lagoon), which received explosive-containing waste water
intermittently during 1943-70.   It now holds an estimated 37,000 cubic yards
of hazardous sludges. A second area under  investigation involves an earthen
and concrete dam across  Brush Creek, which  was used during 1948-56.  The dam
was removed in 1957.  Waste water from Line 1  flowed through a 3.6-acre
sedimentation area where explosives settled out, and the liquids overflowed
the dam into Brush Creek.

    IRP tests conducted  in 1981 and 1983 detected TNT, DDT,  and  RDX  in wells
downgradient of the  lagoon and dam.  An  estimated 100 people obtain  drinking
water from private wells within 3 miles  of  hazardous substances  at the base.

    In 1984, IRP tests detected RDX and  TNT in water from Brush  Creek, and
RDX, TNT,  and lead  in creek sediments.   Surface water within 3 miles
downstream of the site is used for recreational activities.

    Three incinerator-furnace units and  a spray evaporation  pond on  IAAP are
regulated under Subtitle C of the Resource  Conservation  and  Recovery Act
(RCRA).

     Status  (May  1990);   EPA and the Army are negotiating an Interagency
Agreement under CERCLA Section 120.  The agreement  requires  the  Army to submit
schedules for addressing all contaminated areas in  IAAP  and  allows for EPA and
State comment throughout subsequent response  activities.

     Conditions at listing (June 1988);  Lehigh Portland Cement Co.  owns and
operates a portland cement manufacturing facility on  approximately 150 acres
on the north side of Mason City, Cerro Gordo County,  Iowa.  The facility has
been in operation since 1911.  A by-product of the cement manufacturing
process is waste kiln dust, which contains sulfates,  potassium hydroxide, and
chromium.  The dust is placed in piles throughout the facility, and  a large
quantity is also disposed of directly into two of the four abandoned quarries
on the property.  The quarries are filled with water  and drain into  Calmus
Creek directly south of the site.

     In August 1984, the Iowa Department of Water, Air,  and Waste Management
(IDWAWM) conducted a comprehensive study of Calmus Creek and  found
contamination related to Blue Waters Pond, which  is on the Lehigh site. In
April 1985, a consultant to Lehigh started a study of the feasibility of
eliminating Blue Waters Pond.  Also in April 1985, IDWAWM issued  an
Administrative Order under the State water pollution  control  law  requiring
Lehigh to conduct a hydrogeologic investigation of the West Quarry.   Lehigh
installed three monitoring wells and sampled ground water and surface water.
Wells downgradient of the site had significantly  elevated pH  levels  (a maximum
of 11.85), along with elevated levels of potassium, sodium, silicon, sulfates,
total dissolved solids, and total organic carbon.  An estimated 31,000 people
obtain drinking water from public and private wells within 3  miles of the

      Conditions at listing  (June 1988) r  The Northwestern States Portland
 Cement Co.  (NWSPC) Site covers 150 acres in Mason City, Cerro Gordo County,
 Iowa.  In 1950, NWSPC ceased limestone mining operations and abandoned the
 quarry west of the plant. In about 1969, NWSPC began using the West Quarry for
 disposal of cement kiln dust, continuing until April 1985.  Over the years,
 the dumping has reduced the area and volume of the West Quarry.  During this
 same time,  the water level has risen approximately 2 feet per year, filling in
 the quarry so that it now holds approximately 420 million gallons of water.

      The waste kiln dust contains chromium and is very caustic (pH 12.4),
 according to tests conducted by the Iowa Department of Water, Air, and Waste
 Management  (IEWAWM) in October 1979 and August 1983.  Additional sampling by a
 consultant  to NWSPC ,in September 1983 was consistent with earlier data.

      Mason  City municipal wells are within 3 miles of the site and serve a
 population  of about 30,000.   The wells are drilled into the Jordan Aquifer but
 are open to overlying formations.   The Devonian Aquifer, the shallowest
 dependable  source of water for many county residents, is one of the overlying
 formations.   Waste kiln dust has been deposited into this formation.

      Calmus Creek, which  borders the site downstream, shows high pH levels,
 according to tests conducted by a  consultant to the company in 1985.   The
 creek is used for recreational activities.

      On April 2,  1985,  the State issued an Administrative Order under a State
 waste water law requiring the company to cease discharge to Calmus Creek and
 conduct a study to determine the impact of the quarry on ground water.  The
 company submitted a report to the  State dated August 12,  1985.   The discharge
 to Calmus Creek has been  discontinued,  and the ground water study  is
 continuing.

      Status  (July 1990):   In March 1990,  NWSPC,  under a State order,  completed
a remedial investigation/feasibility study to determine the type and  extent of
contamination at the site and identify  alternatives for remedial action.   A
Record of Decision selecting the remedial alternative was signed on June 26,
 1990.                                                                       '

                                 Dubuque, Iowa

     Conditions at listing  (June 1988);  The Peoples Natural Gas Co. Site
covers approximately 15 acres in downtown Dubuque, Dubuque County, Iowa.  Key
City Gas Co. produced a gaseous fuel at the site from 1937 to 1954.  In 1953
and 1954, North Central Public Service Co. acquired all outstanding stock and
assets of Key City Gas, including the site.  In November 1957, Northern
Natural Gas Co., through its Peoples Natural Gas Co., purchased  the site  from
North Central.  In October 1964, Peoples conveyed the eastern four fifths of
the site to the City of Dubuque, which uses it as a garage.  In  January 1985,
Peoples conveyed the remainder of the site to the Iowa Department  of
Transportation (IDOT).

     The main wastes associated with coal gasification are polynuclear
aromatic hydrocarbons  (PAHs), which are found in coal tar, a by-product of the
gasification process, and cyanide salts, which are found in iron oxide waste
produced during purification of the manufactured gas.  Coal tar  waste  was
deposited in underground tanks, and the iron-cyanide waste was buried  on-
site.

     In November 1983, IDOT, which had targeted the site for highway
construction, found a layer of tar in soil samples collected at  the site.  The
samples contained cyanide, phenols, and two PAHs — naphthalene  and
acenaphthalene.  The State and EPA have detected the same contaminants in on-
site wells.  An estimated 60,000 people contain drinking water from municipal
wells within 3 miles of the site.

     The Mississippi River is approximately 500 feet east of the site.
Surface water downstream is used for industrial and recreational activities.
A wildlife refuge is 2 miles downstream, and wetlands are within 0.5 mile.

     Status (May 1990):  Under an April 1989 CERCXA Administrative Order  on
Consent with EPA, Midwest Gas (a successor company of North Central),  IDOT,
and the City of Dubuque are conducting a remedial investigation/feasibility
study (RI/FS) to determine the type and extent of contamination  at the site
and identify alternatives for remedial action.  The RI/FS covers ground water
contamination, as well as soil contamination outside the construction  corridor
of U.S. Highway 61, which consists (roughly) of the western third  of the  site.
The order also calls for Midwest Gas to remove coal tar and contaminated  soil
in the construction corridor and transport the materials to an of f-site
incinerator.  The removal will permit highway construction to proceed.

                                  Keokuk,  Iowa

     Oonditions at  listing (May 1989);  Sheller-Globe Corp. operated an
industrial  landfill and solvent burning area in lee County 4 miles north of
Keokuk, Iowa,  from  1948 to 1972.  The 5-acre site is in a heavily wooded,
rural area.  The land was filled in and sold in 1973 to an individual who
built a home on the site and draws  water from an on-site well.

     Sheller-Globe  Corp.  manufactured rubber products, including automobile
weather stripping,  at a facility adjacent to the disposal area.   Liquids and
sludges from the operation were deposited directly into a ravine with no
system for  diverting surface run-off.   Among wastes deposited, according to
the company, were at least 1,000 drums of paint sludge, methylene chloride,
toluene diisoyanates,  methyl ethyl  ketone, isopropyl alcohol, butyl alcohol,
and resins  containing fluorocarbons.  Solvents were periodically burned in the
open.

     In December 1987 tests,  EPA detected arsenic, chromium, lead, mercury,
nickel, zinc,  benzene, and toluene  in on-site soil, ground water, and surface
water.  An  estimated 1,125 people obtain drinking water from private wells
within 3 miles of the site.

     In December 1987, EPA also observed seepage and an oil sheen on an
intermittent stream near the northeast edge of the site.  The Mississippi
River 2.8 miles downstream of the site is used for recreational boating and
fishing.

     In March  1988,  EPA observed 52 drums on the surface, as well as scrap
rubber and  polyurethane foam.

                              Charles City,  Iowa

     Conditions at listing (June 1988);  The White Farm Equipnent Co.  Dump
occupies approximately 20 acres along the north border of Charles City,  Floyd
County, Iowa.  The dump is an old sand/gravel pit that is bordered  along the
northwest and southern edges by wetlands.  Tractors and other farm  equipment
have been manufactured near the dump since the early 1900s.   Allied Products
Co. purchased the operation in late 1986.

     White Farm Equipment operated on land leased from H. E.  Construction Co.
until it filed for bankruptcy in 1980.  Starting in the 1920s, White Farm's
operations generated foundry sand, sludges, and dust from air pollution
control equipment.  Nearby residents have complained of dust  blowing off the
dump.  White Farm hauled at least 6,300 tons of foundry sand  and 47,000 cubic
yards of sludges to the dump.

     In April 1986, EPA detected arsenic, chromium, copper, lead, nickel, and
zinc in on-site soils, private wells downgradient of the site, and  sediments
and surface water in the adjacent wetlands.  Charles City draws  its drinking
water from the aquifer underlying the site.  An estimated 10,000 people obtain
drinking water from public and private wells within 3 miles of the  site.  The
contaminated wetlands flow into the Cedar River, which is used for
recreational activities.

     Status  (May 1990):  In April 1989, EPA signed an Administrative Order on
Consent with Allied Products Co. and H.E. Construction Co. requiring the
companies to conduct a remedial investigation/feasibility study  (RI/FS).  The
order called for  (1) determining the nature and extent of contamination in
fill material, soils, sediments, surface water, and ground water at the site
and (2) investigating potential hydrologic interactions between  the water
table and the city wells adjacent to the site, and  (3) identifying
alternatives for remedial action.

     The RI/FS is about to be released for public comment.  The  RI/FS
documents low levels of metals in the  fill material and a localized plume of
shallow ground water with organic contamination.

                               Bocatello,  Idaho

     Conditions at listing (May 1989);  The Eastern Michaud Flats
Contamination Site covers 2,530 acres in Fewer County,  Idaho, near  Pocatello.
The Michaud Flats are on the Snake River Plain and are  bounded on the north by
American Falls Reservoir, on the east by the Portneuf River, on the west by
the Rock Creek, and on the south by  foothills of the Deep Creek Mountains and
Bannock Range.  Within the eastern part of the flats are two adjacent
phosphate processing facilities.  FMC Corp. has produced elemental  phosphorus
from phosphate shale ore on 1,400 acres since 1949.  J. R. Sinplot  Co. has
produced a variety of fertilizer products from phosphate ore on 1,130 acres
since 1944.

     Waste water from both facilities has been stored or disposed of  in
unlined ponds.  FMC is phasing out the use of unlined ponds, and  J.R. Simplot
has implemented a waste water treatment system.  In the summer of 1987,  EPA
detected elevated levels of heavy metals in sediments of the unlined  ponds at
both facilities and in waste water at J. R. Simplot.  In addition,  arsenic,
cadmium, and selenium were detected  in monitoring wells in the deep confined
aquifer.

     Public and private wells within 3 miles of the area provide  drinking
water to an estimated 55,000 people  and are also used to irrigate over 2,100
acres of forage crops.  A private well is 800 feet from an on-site  lagoon.  In
1976, the State of Idaho closed a drinking water well downgradient  of FMC due
to elevated arsenic levels.  Currently, no other private or public  water
supply wells are known to be contaminated, although elevated levels of arsenic
were detected in a downgradient spring used for drinking.

     Status  (May 1990);  EPA will soon be sending out general notice  letters
and requests for additional information to FMC, J.R. Simplot, and other
parties potentially responsible for  wastes associated with the site.   EPA will
then investigate the possibility of  those responsible performing  a  remedial
investigation/feasibility study to fully define the nature and extent of
contamination at the site.

                              Soda Springs, Idaho

     Conditions at listing  (May 1989);  Monsanto Chemical Co. has  produced
elemental phosphorus in southeastern Idaho 1 mile north  of Soda Springs,
Caribou County, since  1952.  The 530-acre site  is in a broad, flat valley near
the western base  of the Aspen Range.  Significant agricultural crops in the
area include wheat and hay.  A number of large  industrial complexes are in the
valley, including Kerr-MoGee Chemical Corp., directly across State Highway 34
from Monsanto.  The Kerr-MaGee plant was also proposed for the NPL in
May 1989.

     Monsanto's Soda Springs plant generates a  number of process waste streams
containing inorganic compounds. Most liquid and solid wastes are  stored or
treated in on-site ponds or piles.  Slag constitutes the greatest  quantity of
waste.'  Molten:slag is tapped  from the base of  the electric air furnaces and
poured out to cool in  piles.   Ihe piles  cover a large portion of the site and
are more than 150 feet high.

     As part of a hydrogeological investigation conducted by a Monsanto
contractor in 1984, 31 monitoring wells  were installed around the  facility in
support of existing wells,  and pump tests were  performed on numerous
monitoring wells  and three  on-site wells supplying water to the plant.  Ground
water contamination was detected at the  site.   Ihe contractor identified the
sources as a leaky hydroclarifier and several unlined ponds.  Monsanto has
discontinued use  of the old ponds, installed new lined ponds, and  replaced the
old clarifier.

     On-site monitoring wells  and sediments in  an old unlined pond that
received process  waste water contain arsenic, cadmium, and chromium, according
to tests conducted as  part  of  a November 1987 EPA site inspection. Within
3 miles of the site are public springs and private wells that provide drinking
water to an estimated  3,000 people.

    . Water discharging from an on-site pond to  Soda Creek 2,000 feet away  is
contaminated with cadmium,  according  to  EPA analyses  conducted in  1985.  Water
withdrawn from Soda Canal 1.2  miles downstream  is used to irrigate 4,040
acres.

     Status  (May  1990);  EPA will soon be sending out a  general notice letter
and a request for additional  information to Monsanto.  EPA will then
investigate the possibility of Monsanto  performing a  remedial investigation/
feasibility study to fully  define the nature and extent  of contamination at
the site.

                             Mountain Home,  Idaho

     Conditions at listing  (July 1989);  Mountain Home Air Force Base covers
approximately 9 square miles on a plateau  in El more County southwest of
Mountain Home, Idaho.  The area around the base  is  primarily agricultural.
The base, established  in 1943,  has been under the control of the Tactical Air
Command since 1965.

     Mountain Home Air Force Base is participating  in the Installation
Restoration Program  (IRP), established in  1978.  Under this program, the
Department  of Defense  seeks to  identify, investigate, and clean up
contamination from hazardous materials.  Under IRP,  the Air Force has
investigated numerous  potentially contaminated areas, including two abandoned
landfills,  a waste oil disposal area,  four abandoned and  one active fire
training areas, and the  entomology shop yard, where pesticides were rinsed
from application equipment.  Wastes disposed of  at  these  locations include
solvents and pesticides.

     EPA tests conducted in October 1987 found elevated levels of
tribromomethane (bromoform) in  several on-site wells serving the base.
Bromoform is a component of fire extinguishing agents and is also used as a
solvent.  Over 14,000  people obtain drinking water  and land is irrigated from
wells within 3 miles of  hazardous substances on  the base.

     The Air Force has conducted a study to determine the type and extent of
contamination at the base and identify alternatives for remedial action.  EPA
reviewed the study and found it unacceptable as  it  had not included the units
for which the base had been listed.

     Status (May 1990):  EPA will be entering into  negotiations with the Air
Force and the State of Idaho to adopt  an Interagency Agreement (IAG) under
CERdA  Section 120.  The IAG will specify  units  to  be covered in the workplan
for a remedial investigation/feasibility study.

                               Quincy, Illinois

     Conditions at listing f June 1988);  Adams County Quincy Municipal
Landfills #2 and #3 are approximately 5 miles east of Quincy, Adams County,
Illinois.  Landfill #2 covers 11.75 acres and landfill #3 approximately 40
acres.  In 1973 and 1975, they were permitted by the Illinois Environmental
Protection Agency (IEPA) to accept solid waste.

     As the only operating, permitted landfills in Adams County from September
1972 to August 1978, Quincy landfills received the majority of  the county's
waste, including putrescible, nonputrescible, demolition, combustible,  and
hazardous materials.  IEPA records show that the City of Quincy accepted
liquid industrial waste for disposal into pits until the liquids could  be
pumped into the covered portions of the site.  The site was unlined.  Wastes
disposed of included solvents, acids, sludges containing heavy  metals,  spent
organic solvents used in degreasing, waste water treatment sludges from
electroplating operations, hydraulic oil, machine coolants, thinners, acetone,
and toluene.  An estimated 23,000 drums of hazardous wastes were accepted.
The site involved area fill and trench fill operations.

     Ground water samples taken on-site by IEPA in September 1985, January
1986, and April 1986 showed contamination by 1,1-dichloroethane, 1,1,1-
trichloroethane, methylene chloride, trichloroethylene, benzene, and selenium.
In June 1985 and August 1986, IEPA sampled two nearby private wells.  One  well
was contaminated by 1,1-dichloroethane, dichloroethylene, chloroform,
tetrachloroethylene, and benzene.  (Both wells were closed, and the city
provided an alternative water supply.)  Other wells showed elevated levels of
iron, cyanide, and zinc.  An estimated 300 people obtain drinking water from
private wells within 3 miles of the site.

     In an inspection in 1984, EPA observed leachate seeps and  ponds at the
site, threatening nearby surface waters.  The site is not completely fenced,
making it possible for people and animals to come into direct contact with
hazardous substances.

     In mid-1987, a contractor for a number of parties potentially responsible
for wastes associated with the site started a remedial investigation/
feasibility study (RI/FS) to determine the type and extent of contamination  at
the site and identify alternatives for remedial action.

     Status (May 1990);  In April 1990, as part of the RI/FS, two pump  tests
were conducted to determine the relationship between the shallow and deep
aquifers and to determine if multiple ground water pathways exist at the site.
The test report is scheduled to be completed in July 1990.

     Conditions at listing (June 1988);   Beloit Corp.  has occupied a 175-acre
site in the Village of Rockton, Winnebago County,  Illinois,  since 1961.  There
are two operations at the site:  a plant for manufacturing wet-end paper-
making machines,  and a research and development facility for designing and
demonstrating the machines to prospective customers.

     The facility purchases clean virgin pulp to make multilayered paper
products.   The waste paper and paper fibers generated go to  three unlined
surface impoundments.  The paper fiber sediment from the bottom of the
impoundments  is spread on the ground in accordance with a State permit issued
in December 1983.

 ,.-(, .-Qrvrsite  monitoring wells contain 1,1,1-trichloroethane, 1,1-
dichlbrbethane,  and 1,1-dichloroethylene,  and nearby private wells contain
trichloroethylene, according to tests conducted in November  1985 by Beloit
Corp.  An estimated 15,00(3 people obtain drinking  water from public and
private wells within 3  miles of the site.   The Winnebago County Department of
Public Health,  the Illinois Environmental Protection Agency  (IEPA), and the
Illinois Department of Public Health are working together on a program to
monitor ground water in the Rockford area.

     In May 1983,  IEPA found 1,1,1-trichloroethane, trichloroethylene, and
tetrachloroethylene in sediments in the impoundments and in  November 1985
found toluene in water in the impoundments.  Rock  River is less than 50 feet
from Beloit's surface impoundments.   local surface water is  used for

                             Taylorville, Illinois

     Conditions at listing  (June 1988);  Central Illinois Public Service  Co.
 (CIPS)  formerly operated a coal gasification plant on a 1.0-acre site in
Taylorville, Christian County, Illinois.  The site is bordered by Webster
Street  and Manners Park on the east, the CIPS pole storage yard  and N&W
Railroad on the west, private residences on the north,  and a large  wooded area
to the  south.  The site currently consists of an office building with a gravel
parking lot to the west and an undeveloped lot to the south.

     The gas plant was constructed in 1892 and operated by Taylorville Gas  and
Electric Co. until 1912, when it was acquired by dPS.  Operations  stopped  in
1932.   CIPS sold the property in 1961.

     In producing a  commercial fuel, the process generated coal  tar,  which
contains polynuclear aromatic hydrocarbons (PAHs) and other impurities that
were periodically removed and sold or given away for use as road oil, roofing
tar, or a pesticide.  When CIPS abandoned the facility, the abcveground
structures were razed.  Underground tanks and other equipment  remained in
place.  The tar remaining in the tanks was covered with miscellaneous debris
and fill.

     Contamination at the Taylorville site was first suspected when Apple
Construction Co., which acquired the site in April 1985, was excavating a
trench  for  a septic  tank drainage line.  The trench was directly adjacent to
and east of a storage tank.  Workers noted strong odors, discoloration of the
excavated soils, and a dark viscous material throughout the soil.  CIPS was
notified of the problems and immediately began an investigation.

     By mid-1986, CIPS confirmed the presence of PAHs,  including benzo(a)
pyrene, anthracene,  and phenanthrene, as well as benzene and toluene, in  soils
and ground  water within the site boundaries.

     Soils/sediments and ground water off-site and, to  a lesser  extent surface
water,  are  similarly contaminated.  An estimated 12,700 people obtain drinking
water from  public and private wells within 3 miles of the site.   Contaminants
were found  as far away as the South Fork of the Sangamon River,  0.4 mile  from
the site.   Local surface water  is used for recreational activities.

     The site is partially fenced, making it possible for people and animals
to come into direct  contact with hazardous substances.

     In December 1986, CIPS purchased the site from Apple Construction Co.   In
January 1987, dPS began preliminary remedial activities at the  site
consisting  of excavation and disposal of contaminated soil.  The materials
were transported to  a hazardous waste facility regulated under Subtitle C of
the Resource Conservation and Recovery Act.  In cooperation with the Illinois
Environmental Protection Agency (IEPA), CIPs is investigating  a  long-term
solution.

     Status (May 1990):  dPS has fenced the site.  In  cooperation with IEPA,
CIPS is developing a plan to identify alternatives for  remedial  action.

nonradioactive  elements from monazite and other ores.   Later, the property was
used for the manufacture of gaslight mantles (which contain thorium),
mesothorium, and,  during World War II, hydrofluoric acid.  Ownership of the
facility changed  from Lindsay to American Potash & Chemical in 1958 and to
Kerr-McGee Chemical Corp.  in 1967.  Operations at the property continued until
1973, when Kerr-MoGee,  the current owner, closed the facility.

landfill and around and under tennis courts adjacent to it.  Contaminated
material around (not under) the tennis courts was excavated and moved onto an
area of  surface contamination, which was then fenced and posted.

Site is in West Chicago and DuPage County, Illinois.  Ihe site covers the
general area of elevated radiation levels adjacent to the Kerr-MaGee Chemical
Corp. facility on the east  (about 30 acres), as well  as other adjacent areas
and isolated spots of elevated radiation levels.  About 15,000 people live
within 3 miles of the site.

     In 1931, Lindsay Light & Chemical Co. established a mill called the "Rare
Earths Facility" in West Chicago for the extraction of thorium and
nonradioactive elements from monazite and other ores.  Later,  the  property was
used for the manufacture of gaslight mantles  (which contain thorium),
mesothorium, and, during World War II, hydrofluoric acid.   Ownership of the
facility changed from Lindsay to American Potash  & Chemical in 1958  and to
Kerr-McGee Chemical Corp. in 1967.  Operations  at the property continued until
1973, when Kerr-MpGee, the current owner, closed  the  facility.

     In 1978, the U.S. Nuclear Regulatory Commission's contractor  located 75
spots of elevated radiation levels in the residential areas.   Since  that time,
the number has grown to around 87.  Overlying many of these spots  adjacent to
the Kerr-MoGee facility is an area of generally elevated radiation levels.
Although the general area of contamination may  be due, in part,  to long-terra
emissions from the facility, the primary source of contamination is  believed
to be the result of specific incidents such as  spills or use  of  contaminated
materials as fill.

     Status (January 1986);  Because of  an administrative error  during the
public comment period, EPA is extending  the comment period  on this site for an
additional 60 days.

     Status (May 1990):  Rerr-McGee has  excavated contaminated soil  at many
properties within the West Chicago city  limits  and removed  them  to the Rare
Earths Facility for storage.  No work has been  done at properties  outside the
city limits.  The Kerr-MoGee activities  are voluntary, without EPA oversight
or involvement.

     Conditions at  listing (October 1984):   The Kerr-MsGee (Sewage Treatment
Plant) Site covers  about 23 acres in West Qiicago, Illinois.   About 15,000
people live within  3 miles of the site.

     In 1931, Lindsay Light & Chemical Oo.  established a mill called the "Rare

Kerr-MoGee Chemical Corp.  in 1967.  Operations at the property continued until
1973, when Kerr-MoGee, the current owner, closed the facility.

     Ihe original sewage treatment plant was built in 1919 and included two
septic tanks.  Over the  years,  the plant changed, and the tanks were filled
with radioactive materials.  In addition, fill,  including radioactive
materials, was placed in other  areas of the site.  While modernizing the
plant, the city has located many surface and subsurface areas of
contamination.  To  allow the modernization  to  continue, any areas that
obstruct construction are expected to  be excavated and the material placed in
a designed storage  area  on the  site.

     Status  (January 19861;  Because of an  administrative error during the
public comment period, EPA is extending the comment period on this site for an
additional 60 days.

     Status  (May 1990):   As modernization continued at the sewage treatment

                              Belvidere, Illinois

     Conditions at listing (October 1989);  The MIG/Dewane landfill  covers  50
acres on Business Route 20E in Belvidere, Boone County, Illinois.  The site is
in a rural area with cxxnmercial and agricultural operations nearby.   Since
1976, MIG/Dewane has accepted household refuse and special wastes such as
paint sludges and organic solvents.  Approximately 480,000 gallons of
hazardous waste containing arsenic, cadmium, lead, nickel, and cyanide were
dumped into the landfill, according to the Illinois Environmental Protection
Agency.

     In June 1986, EPA found 1,1-dichloroethane in on-site monitoring wells
into the upper sand and gravel aquifer.  The site is located near Belvidere's
municipal water wells and private wells.  One municipal well and 28% of the
private wells are obtaining water from the upper sand and gravel aquifer.
There is no confining layer to prevent migration of contaminants from the
landfilled area to the upper aquifer.  An estimated 16,300 people obtain
drinking water from wells within 3 miles of the site.  A  private well is 2,500
feet from a contaminated well on the site.

     In 1985, the State Attorney General, on behalf of Boone County, filed a
lawsuit against MIG/Dewane because the company was expanding the landfill
beyond its permit.  After the suit went to the Illinois Supreme Court, the
site was ordered closed in June 1988.  It ceased operations in July 1988.

     Status fMav 1990);  The site operator has declared bankruptcy and left
the State.  Wastes are exposed on about 10 acres of the site.   The State is
conducting a search to identify parties potentially responsible for wastes
associated with the site and may request that they cover  the exposed wastes.
The State is also pumping leachate from a collection lagoon to prevent
overflowing.

     EPA emergency staff is evaluating the site to determine if a removal
action is warranted at this time.

                                Elkhart,  Indiana

      Conditions at listing  (June 1988);  Consolidated Rail Corp.  (Oonrail) has
 operated a rail yard on County Road 1 at the southwestern edge of Elkhart,
 ElMiart County, Indiana, since 1976. Previously, the 675-acre property had
 been a rail yard for New York Central Railroad  (1956-68)  and Penn Central
 Railroad (1968-76).

      The Indiana Department of Environmental Management has  documented
 numerous spills at the rail yard since 1976.

      In June 1986, EPA's emergency  removal program was  asked by the Elkhart
 County Health Department to confirm analyses indicating that local wells were
 contaminated with carbon tetrachloride and trichloroethylene (TCE).  EPA's
 investigation identified five areas covering about 5 acres requiring further
 study:  the diesel shop, the area surrounding oil  and water  tanks,  several
 areas where wastes may have been buried, the shop  where car  tanks were
 cleaned, and the Crawford Ditch, which flows into  the St. Joseph  River.
 Analyses indicate that soils in some of these areas  contain  carbon
 tetrachloride, and wells downgradient of the rail  yard  contain carbon
 tetrachloride, TCE, tetrachloroethylene, chloroform, and  dichloroethane.  EPA
 installed activated carbon units at residences with  contaminated  wells.  EPA
 analyses indicate a plume of contaminated ground water  that  is 1.5-2 miles
 long and empties into the St. Joseph River.   An estimated 55,000  people obtain
 drinking water from Elkhart municipal wells  and private wells within 3 miles
 of the site.

      Status fMav 19901:  In June 1988, EPA issued  a  "special notice letter11
 offering Conrail the opportunity to conduct  a remedial
 investigation/feasibility study  (RI/FS) to determine the  type and extent of
 contamination at the site and identify alternatives  for remedial  action.  In
 September 1988, EPA notified Conrail its response  could not  be considered an
 acceptable "good faith" offer.  Accordingly,  EPA is  conducting the RI/FS;
 field work began in August 1989.  Initial data confirmed  the existence of two
 plumes of contaminated ground water.  EPA is reviewing  the data to assess the
 need for additional field work and  interim remedial measures.

      Field investigations by a Conrail contractor  found TCE  and carbon
 tetrachloride in soil and ground water within the  rail  yard.

     Conditions at listing  (June 1988V;  Tippecanoe  Sanitary landfill,  Inc.
(TSL) operates a 51-acre landfill in lafayette,  Tippecanoe County, Indiana.
In 1971, the company received a permit from the State to accept municipal
waste.  Open dumping had occurred for  an unknown period prior to that date.
In 1978, the State did not  renew the site's operating permit because of
shallow ground water and highly permeable  subsurface materials at the site.  A
series of appeal** followed, and the facility is currently operating  without  a
permit.

     In 1979, ALCOA, Lafayette, Indiana, advised the State that its  aluminum-
lime sludge, which had been hauled  to  the  site since 1973, had been  found  to
contain significant  levels  of ECBs.  Disposal  of the sludge  ceased,  but
considerable quantities  had already been deposited at the site.

     In December 1983, the  Indiana  State Board of  Health found that  a nearby
well contained PCBs  and  acetone, as well as lead and cadmium, at levels
exceeding Federal primary drinking  water standards.   An estimated  81,000
people obtain drinking water from public and private wells within  3  miles  of
the site.

     In May 1987, the  Indiana Department of Environmental Management (IDEM)
started litigation to  permanently enjoin TSL from  operating.

     Status  (Mav 1990);  A  Consent  Decree  with IDEM  dated November 29,  1988
required TSL to stop accepting solid wastes by October  1, 1989, remove  all
personnel and equipment  by  October  31, 1989, and place  a cover of  soil  on
filled areas.

     TSL  filed a bankruptcy petition in February 1989.   The  landfill closed in
September 1989.

     A TSL contractor  started to cap the  filled areas,  but the capping  is  not

     Conditions at listing (June 1988);  Ihe Whiteford Sales and Service
Inc./Nationalease Site covers approximately 7  acres on Sample Street in South
Bend, St. Joseph County, Indiana.  Ihe site operated as Whiteford Sales and
Service during 1960-83 and as National ease during  1983-87.   Both companies
leased trucks and semitrailers.  Currently, the  operation is known as
Whiteford-Kenworth, Inc.

     Approximately 396,000 gallons of  degreasing solvents and sludge resulting
from cleaning of the trucks and semitrailers were  deposited into three unlined
dry wells, each 4 feet in diameter and 6 feet  deep.  Tests conducted by St.
Joseph County in May 1985 found that on-site soil  is contaminated with
inorganic and organic compounds, including lead, arsenic, ethylbenzene, and
toluene.  Soil on the site is permeable, facilitating  the movement of
oiaitaminants into ground water.  Approximately 237,000 people draw drinking
water from public wells within  3 miles of the  site.  The  nearest well is about
900 feet from the site.

     Status  (May 1990);  On June 19, 1987, Whiteford and  the Indiana
Department of Environmental Management signed  a  Consent Decree requiring
Whiteford to remove 4 feet of soil in  all directions from around the dry
wells.  Whiteford has not met this requirement.  In June  1990, EPA is to start

                              Junction City, Kansas

      Conditions at listing  (July 1989) ;Fort Riley is near Junction City,
 Kansas, north of where the Republican and Smoky Hill Rivers meet  to form the
 Kansas River.  Most of the 152-square-mile Army base is in Riley  County, with
 the remainder in Geary County.  The majority of the developed areas are in the
 southern portion, along the Republican and Kansas Rivers.  The area around the
 fort is predominantly rural and agricultural.

      Established in 1853, Fort Riley was a major fort in this area during the
 Civil  War.  It is currently the headquarters of the U.S. Army First Infantry
 Division  (mechanized) and host to over a dozen other units of the Department
 of Defense.  There are six main centers of activity in Fort Riley.  Camp
 Forsyth is on the floodplain of the Republican River, immediately north of
 Junction CityJ  Camp Funston is on the floodplain of the Kansas River,
 immediately west of the Town of Ogden.  Camp Whitside is on the Kansas  River
 floodplain just west of Camp Funston.  The Main Post is on the edge of  the
 Kansas River floodplain across from Marshall Air Field.  Custer Hill  is in the
 upland several miles north of the Kansas River.

      Operations on the facility have been varied, including seven landfills,
 numerous motor pools, burn and firefighting pit areas, hospitals, dry
 cleaning, shops, and pesticide storage and mixing areas.  Vinyl chloride,
 pesticides, waste motor oils, degreasing solvents, tetrachloroethylene
 (perchloroethylene), and mercury were deposited in landfills below the  water
 table  and spilled or dumped on the ground adjacent to buildings.  The most
 serious problems are associated with a sanitary landfill at Camp  Funston,
 spills of dry cleaning solvents at the Main Post, and pesticide residues, also
 at the Main Post.

      Fort Riley is participating in the Installation Restoration  Program
 (IRP), established in 1978.  Under this program, the Department of Defense
 seeks  to identify, investigate, and clean up contamination from hazardous
 materials.  A 1984 IRP study indicates that vinyl chloride is present in
 shallow (15-25 foot) monitoring wells downgradient of the Camp Funston
 landfill.  The alluvial aquifer along the Republican and Kansas Rivers  is the
 sole source of drinking water for Fort Riley, Ogden, and Junction City.

      A Fort Riley water supply well is 0.7 mile from a former dry cleaning
 building.  Municipal and Army wells within 3 miles of hazardous substances on
 the base provide drinking water to an estimated 46,800 people.  Ground  water
 is also used locally for irrigation.

      The Kansas River along Fort Riley is used for fishing and other
 recreational activities.  Bald eagles, designated by the U.S. Fish and
 Wildlife Service as an endangered species, are seen regularly on  the  base.

      Status (May 1990);  EPA, the Army, and the Kansas Department of  Health
 and Environment (KDHE) are negotiating an Interagency Agreement under CERdA
 Section 120.  The agreement will require the Army to submit schedules for all
 activities and provides for EPA and KDHE oversight of these activities.

                               Auburn, Kentucky

     Conditions at listing (June 1988);  The Caldwell Lace Leather Co., Inc.,
Site consists of three tannery waste areas in Logan County along the south
side of Cemetery Road (State Highway 1039) approximately 2.5 miles northwest
of Auburn, Kentucky.  The areas have received wastes since 1972.  Until 1985,
the site was owned by Caldwell and received waste generated by leather-tanning
processes at its plant in Auburn.  In November 1985, North Park, Inc., a
subsidiary of Auburn Leather Co., purchased the plant and disposal areas.   The
plant no longer conducts tanning operations.

     During 1972-82, wastes, including chrome and vegetable tanning wash
sludge, fleshings, screenings, and leather and gasket scraps, were buried in
trenches or placed in unlined lagoons in a 5.5-acre area of the property.   The
sludge was generated from a chromium or vegetable tanning solution  (water-
soluble extracts from various plant parts) used to stabilize collagen fibers
so that they are no longer biodegradable.  Fleshings and screenings resulted
from processes in which the leather is prepared for tanning by removing the
hair and tissue from the flesh side of the skin.

     The second disposal area is a 29.6-acre landfarm.  In July 1982, the
company received a conditional permit from the Kentucky Natural Resources and
Environmental Protection Cabinet (KNREPC) to mix the sludges into the soil.
The landfarm stopped operating in 1985.

     In March 1983, KNREPC granted a conditional permit to Caldwell for the
third area, a 5.1-acre landfill adjacent to the old trench/lagoon area, to
accept only solid wastes, including the screenings, fleshiJigs, leather scraps,
and gasket scraps.  In 1986, North Park, Inc., received a solid waste permit
for the landfill from KNREPC.  The company's operations generate only leather
trimmings and scrap.

     In July 1983, KNREPC detected chromium, including the most toxic
hexavalent form, in a private well 1,200 feet from the landfill area.  The
well has been taken out of service.  An estimated 660 people obtain drinking
water from private wells within 3 miles of the site.  Subsurface conditions
are such that ground water migrates readily and cxsntaminants can reach surface
waters.  The closest surface water intake is in Auburn, approximately 2 miles
southeast of the site where Black Lick Creek originates.

     KNREPC has documented violations of State waste management laws and
regulations since 1978.  In September 1984, Caldwell entered into an Agreed
Order with the State to remedy past violations and prevent further violations.
The closure consists of a three-phase approach involving application of lime
and fertilizer, regrading and revegetation, and ground water/surface water
monitoring.

     Status  (May 1990);   All phases of the three-phase closure plan were
completed in late 1989.  The landfarming area was never closed.

                                Olaton, Kentucky

     Conditions at listing  (June 1988):  The Fort Hartford Coal Co., Inc.,
Stone Quarry in Olaton, Ohio County,  originally provided limestone for parkway
construction in western Kentucky.   Since 1981,  the 100-acre  area has been used
to store secondary dross  (a by-product of  aluminum recycling) from Barmet
Aluminum Corp. 's smelter  in Livia,  Kentucky.  According to Fort Hartford Coal,
by late 1986 Barmet had deposited more than 712,000 tons of  dross  into the
quarry.  Dross contains heavy metals  (including barium,  cadmium, chromium,
lead, copper, and  manganese)  and reacts  violently with water to form several
gases, including ammonia.   EPA  detected  ammonia in the air around  the  storage
areas during a December 1986 inspection.

     In 1984, the  Kentucky  Department of Environmental Protection  found  high
levels of ammonia  in  an unnamed stream that originates in the waste.   Run-off
from the quarry flows into  the  Rough  River, which is  used for recreational
activities.  The waste was  deposited  below the  water  table,  thus threatening
ground water.  An  estimated 700 people obtain drinking water from  wells  and
springs within 3 miles of the site.

     Status (January  1990);  Barmet contested the proposed listing of  the Fort
Hartford Site and  filed a civil action against  EPA and the State on November
8, 1988 in the U.S. District Court.  In  November 1988,  Barmet also filed for a
Temporary Restraining Order to  keep EPA  from  (1) placing this site and the
Brantley Landfill  Site on the final NPL  until their comments had been
addressed and  (2)  keep EPA  from sending  letters to other parties potentially
responsible for wastes associated with the sites informing them of their
potential liability.   After the request  for this order was denied, EPA sent
the letters.

     In December 1988,  EPA, in  response  to a citizen's complaint,  identified
two areas where the quarry  roof had collapsed on his  property.  Subsequently,
additional roof collapse  areas  were identified  that provide  actual or
potential pathways by which water can drain into the  dross storage areas.

     In January 1989, EPA sampled area private  wells.  No evidence was found
of contamination from dross stored  at the  site. However, two samples  had
elevated  levels of manganese and/or iron.   Storage operations continue.   By
October 1989,  1.2  million tons  of dross  were in the quarry.

     On September  20, 1989, EPA and Barmet signed a CERCIA Administrative
Order on Consent requiring  Barmet to  conduct a  remedial investigation/
feasibility study  (RI/FS) to determine the type and extent of contamination at
the site and identify alternatives  for remedial action.  Barmet submitted an
Expedited Response Action Plan  on October  20, 1989 under the order. Barmet
will  (1)  identify  all areas where waste is in contact with water and where
water is  entering  the quarry and (2)  isolate wastes from water.

     Status  (May 1990):  The civil  action  against EPA was dismissed when the
judge ruled he did not have subject matter jurisdiction.

     After EPA reviewed Barmet's workplans, Barmet started the Expedited
Response Action in mid-May 1990.

                                Maoeo, Kentucky

     Conditions at listing (June 1988);  Green River Disposal, Inc., disposed
of waste on Kelly Cemetery Road in a rural area in east Daviess County near
Maceo, Kentucky, during 1970-84.  The 14-acre site was used for landfilling
and surface disposal.  In January 1975, the site was permitted as a solid
waste landfill by the State of Kentucky.  The permit expired in January  1988.
The facility became inactive in 1984.

     Waste from Kentucky industries was disposed of at the facility during
1978-84.  According to records of the Kentucky Department for Environmental
Protection (KDEP), this waste was generated in part by Martin Marietta
Aluminum (now Commonwealth Aluminum) in Lewisport and by Green River Steel
Corp., W. R. Grace & Co., and General Electric Co., all in Owensboro.  The
waste included aluminum dross saltcake, steel dust, phenolic resin, and  paint
waste, which were buried along with sanitary waste as part of the facility's
daily operations; 976 drums of waste were disposed of at the facility.   In
January 1985, Martin Marietta and Grace removed 776 drums and transported them
to a hazardous waste facility regulated under Subtitle C of the Resource
Conservation and Recovery Act.

     In June 1985, a site investigation by KDEP revealed that two drums  at the
site contained chromium, lead, cyanide, PCBs, arsenic, and barium,  and that
on-site private wells contained arsenic and barium.  An estimated 500  people
obtain drinking water from private wells within 3 miles of the site.

     According to KDEP, surface water is threatened because wastes  are in-
adequately covered and run-off is uncontrolled.  Blackford Creek, which  is
used for irrigation and recreational activities, is within 3 miles  downstream
of the site.

     The Green River Disposal, Inc., facility has a history of leachate
outbreaks, underground fires, and acceptance of unauthorized waste.  In
January 1983, the facility entered into an Agreed Order with KDEP.  The  order
was prepared as a result of permit violations and designed to deal  with  the
environmental problems existing at the landfill and to bring the facility into
compliance with solid waste regulations.  On August 6, 1986, the State
received a Notice of Bankruptcy from the company under Chapter 7 of the
Federal bankruptcy code.

     Status (May 1990);  EPA has issued a CERCXA Unilateral Administrative
Order requiring Commonwealth Aluminum, W.R. Grace & Co., General Electric Co.,
and Athlone Industries, Inc., all of whom sent wastes to the site,  to  conduct
a removal that in part encompasses restricting access to the site and
controlling leachate.

     In May 1990, the four companies entered into a CERCLA Administrative
Order on Consent with EPA.  Under the order, they will conduct a remedial
investigation/feasibility study to determine the type and extent of
contamination at the site and identify alternatives for remedial action.

oil, sediments, and waste water to the site via pipeline from its petroleum
hydrocarbon recycling plant located approximately 0.25 mile to the southeast.
During the life of the facility, 11 irregularly shaped earthen pits were
constructed; five contain oily wastes, three contain oil and waste water,  and
three contain principally waste water.  Approximately 3 million gallons of
material are in the pits.  Although the pits were constructed to isolate the
wastes, they are connected by a series of trenches or pipes that allow mixing.

     Two aboveground tanks are also located on the Combustion, Inc., property:
a 20,000-gallon tank and a 30,000-gallon tank.  These tanks were used

Inc., the previous owner of the property, may have treated potentially
hazardous chemicals other than waste oils on the site.

     Combustion, Inc., began to close the facility late in 1980, and by May
1982, had completely shut down operations.  In October 1983, the Louisiana
Department of Environmental Quality (LDEQ) analyzed wastes from the site and
found they contained PCBs, volatile organic chemicals, and heavy metals.   In
February 1985, LDEQ detected lead and thallium in ground water at the site,
and volatile organic chemicals in the air.  Ground water within 3 miles of the
site is used for irrigation and drinking water.  About 500 people live within
1 mile of the site.

     On January 18, 1984, a State Compliance Order was issued to the site
owner.  The property has allegedly been sold to unknown parties, and the
former owner says he is financially unable to clean up the site.

     Status  (June 1988);  After this site was proposed in June 1986, new
technical information became available.  Hence, EPA is reproposing this site
to allow an additional 60-day comment period.

     Louisiana has an enforcement agreement with EPA to take the lead on site
cleanup.  LDEQ is working with Combustion, Inc., on a workplan for a remedial
investigation/feasibility study (RI/FS) to determine the type and extent of
contamination at the site and identify alternatives for remedial action.

     Status  (May 1990);  A number of the parties potentially responsible for
wastes associated with the site prepared a preliminary Public Health
Evaluation and Endangerment Assessment in February 1990 and a preliminary  PI
report in April 1990.  LDEQ and EPA are reviewing the documents.  The work is
proceeding under a State enforcement order.

                              Kalamazoo, Michigan

     Conditions at listing (May 1989);  The Allied Paper,  Inc./Portage
Creek/Kalamazoo River Site involves PCB contamination of an Allied Paper,
Inc., property, in Kalamazoo, Kalamazoo County, Michigan,  plus a  3-mile
stretch of Portage Creek from Kalamazoo to where the creek meets  the Kalamazoo
River, and a 35-mile stretch of the Kalamazoo River.

     Allied Paper, Inc., has operated paper mills on a 80-acre property at
2030 Portage Road in Kalamazoo since 1925.  Ihe company, a subsidiary  of SCM
Corp., recycled and deinked paper, including carbonless copy papers, which
contained 3.4% by weight of Aroclor, a PCB, from 1957 to 1971.

     In 1986, the Michigan Department of Natural Resources (MDNR) detected
PCBs in several places in the 80-mile stretch of the Kalamazoo River between
Kalamazoo and Lake Michigan.  Contamination is primarily in the sediments,
although the water column and fish are also contaminated.  According to MDNR,
the contamination begins at the point were Allied's Bryant Mill Pond
discharges to Portage Creek.

     MDNR tests conducted in October 1985 also found PCBs  (Aroclor 1242 and
1254) in monitoring wells around a landfill on the Allied  property, two seeps
from a sludge disposal area, and a discharge to Portage Creek.  An estimated
142,000 people obtain drinking water from public wells within 3 miles  of the
site, the nearest 1.1 miles from the site.  No alternate unthreatened  sources
of water are now available.

     In 1977, the Michigan Department of Public Health issued an  advisory
warning against eating fish in the river because they were contaminated with
PCBs.  In 1984, MDNR began a long-term project to clean up the river after  it
was listed in the Michigan Environmental Response Act.  MDNR has  conducted
extensive sampling to determine the extent of contamination.

     On December 2, 1987, the State filed a complaint under CERdA Sections
107 and 113, the Resource Conservation and Recovery Act, the Federal Water
Pollution Control Act; the Toxic Substances Control Act, and three Michigan
laws.  The complaint called for Allied Paper and SCM Corp. to stop the release
of hazardous substances into the environment and pay cleanup costs.  In
response, the companies have undertaken studies of the extent of  the PCB
contamination, the quantities of PCBs in Bryant Mill Pond, and possible
remedial actions.

     Status (May 1990);  MDNR is considering various alternatives for  the
site.

                          Sault Saiitte Marie,  Michigan

     Conditions at listing (June 1988);  The  Cannelton  Industries, Inc., Site
covers 75 acres along the south bank of the St. Mary's  River about 1.5 miles
west of the downtown area of Sault Sainte Marie, Chippewa County, Michigan.
Starting early in the 19th century, Northwestern leather Co. manufactured
leather products on  the site,  dumping  tannery wastes on 5 acres located in the
100-year floodplain  of  the St. Mary's  River.  The waste was disposed of to a
depth of 6 to 8 feet and left  uncovered.  An  estimated  10,000 cubic yards were
disposed of, as observed from  the depth of wastes along the bank and the area
void of vegetation.   Marshland borders the site on two  sides.

     In 1954-55, Fibron Limestone Co.  (a subsidiary  of  Algoma Steel Corp.,
Ltd., of Canada) purchased the 75 acres.  Subsequently, the property was
transferred to Cannelton Industries, Inc., another Algoma subsidiary.  The
property was intended for construction of a manufacturing plant that was never
built.  Algoma dismantled various structures  that were  considered hazardous.
No manufacturing has been carried out  on the  site since 1958 and hence  no
industrial waste has been generated, according to Algoma.  The site is not now
in use.

     On-site soils and  adjacent river  sediments contain extremely high  levels
of chromium, lead, copper,  cyanide,  and mercury, according to tests conducted
in 1979 by Sault Sainte Marie  State  College and the  Michigan Department of
Natural Resources.   Chromium,  lead, manganese, arsenic, and iron well in
excess of drinking water standards were also  found in ground water in the
middle of the disposal  area.  An estimated 1,200 people obtain drinking water
from private wells within 3 miles of the site, the nearest about 1 mile from
the site.

     Sault Sainte Marie,  Ontario, withdraws water from  the St. Mary's River
approximately 2 miles downstream of  the old tannery  disposal site.

     The dump area is unfenced, making it possible for  people and animals  to
come into direct contact with  hazardous substances at the site.  Bald eagles
feed and nest within 2  miles of the  site.

     In 1986, Algoma Steel agreed informally  with the State to construct (1) a
wall along the shore of the St. Mary's River  to prevent wave and ice action
from removing solid  material from the  site and  (2) an impermeable clay  cap to
prevent erosion and  prohibit rainwater from infiltrating the site.  To  date,
the company has taken no action.

     Status (December 1988):  EPA is conducting a remedial investigation/
feasibility study  (RI/FS) to determine the type and  extent of contamination at
the site and identify alternatives  for remedial action.

     Status (May 1990):  In the spring of 1989 under a  Consent Order with  EPA,
Algoma Steel installed  a sprinkler system as  a temporary measure in a 2-acre
barren zone with a history of  fires.   In November 1989, Algoma Steel completed
a wall to control erosion along the shoreline of the barren zone.  Discussions
are underway concerning what further actions  should  be  taken in the zone.

                              Muskegon, Michigan

     Conditions at listing (June 1988);  Peerless Plating Co. started
operating an electroplating shop on a 1-acre site at 2554 Getty Avenue in
Muskegon, Muskegon County, Michigan, in 1937.  The site is surrounded by
commercial, industrial, and residential areas.  The plant closed  in June 1983
as a result of State and local enforcement actions, labor problems, and
financial difficulties.

     Operations at the plant involved toxic, corrosive, reactive,  and
flammable chemicals.  According to the Michigan Department of Natural
Resources  (MCNR), wastes containing heavy metals were discharged  into three
unlined lagoons at the rear of the facility.  MCNR also determined that
manholes inside the plant discharged directly onto the ground and that drummed
wastes were stored on-site.

     In September-October 1983, EPA used CERdA emergency funds in a  removal
action at the site.  EPA removed 37,000 gallons of sulfuric acid,  nitric acid,
chromic acid, cyanide plating solution, chromium plating solution,
hydrochloric acid, and trichloroethylene.  Also, the lagoons were drained;
soil was removed from the lagoon areas; the interior of the building  was
cleaned; vats, lines, and tanks were decontaminated; sewer lines  were sealed;
and cyanides and nitric acid were neutralized on-site.  Hazardous materials
were removed to a facility regulated under Subtitle C of the Resource
Conservation and Recovery Act.  Approximately 15,000-20,000 gallons of sludges
and liquids remain on-site.

     In 1985, EPA detected cadmium, chromium, cyanide, trans-1,2-
dichloroethylene, and trichloroethylene in an on-site well.  An estimated
1,500 people obtain drinking water from private wells within 3  miles  of the
site.  The nearest well is less than 100 feet from the site.

     The site is on a nearly  level lake plain.  Little Black Creek, which
empties into Lake Manor, is a major drainage pathway.  The lake is used for
recreational activities.

     Status  (Mav 1990);  In July 1989, EPA began planning a remedial

                            Cannon Falls, Minnesota

     Conditions at listing  (October 1989);  Dakhue Sanitary Landfill covers 80
acres approximately 3.5 miles north of Cannon Falls in a rural agricultural
area of Dakota County, Minnesota.  Since  1971, the owner has had a permit from
the Minnesota Pollution Control Agency  (MPCA) to accept  municipal wastes.
MPCA estimates that through 1986, 817,000 cubic yards  of solid waste
(primarily norihazardous industrial and municipal waste)  have been disposed of
at the landfill, which has no liner.

     MPCA analyses in 1985 and 1987 of shallow monitoring wells on the site
detected volatile organic compounds, including 1,1-dichloroethylene,
tetrachloroethylene, methylene chloride,  cis-l,2-dichloroethylene, and
chloroform.  The shallow ground water is  used for drinking  water by about 500
residents within 3 miles of the site and  for irrigation  of  an estimated 6,500
acres.  The nearest drinking water well is about 1,200 feet from the site.

     The area near the landfill consists  of gently rolling  hills with a gentle
slope toward the south.  Pine Creek is 1  mile south of the  site, and Cannon
River  is nearly 3 miles to the south.

     In May 1980, MPCA issued Dakhue Sanitary Landfill a Notice of
Noncompliance for failure to comply with  established operating procedures and
failure to submit water monitoring reports.  In November 1984, MPCA issued a
Notice of Violation for failure to submit work required  by  the landfill
permit.  In June 1987, the  company declared bankruptcy under Chapter 7 of the
Federal bankruptcy code.

     Status (Mav 1990^:  In the fall'*of 1989, MPCA  installed four new

                            Jasper County, Missouri

     Conditions at listing  (June 1988) ;  The Oronogo-Duenweg Mining Belt is
located in Jasper County, Missouri, and comprises a portion of the  Tri-State
Mining District of Missouri, Kansas, and Oklahoma.  Two other Superfund sites
in the district, Cherokee County in Kansas and Tar Creek in Ottawa  County,
Oklahoma,  were placed on the NEL in September 1983.  Superfund-financed
remedial activities are ongoing at these sites.

     Lead and zinc ores, as well as some cadmium ores, were mined,  milled,  and
        throughout Jasper County from 1848 to the late 1960s.  Mining efforts
were originally performed by small independent companies that were later
organized into larger mining operations.

     Abundant mining activities occurred in an area of 2 by 10 miles between
Oronogo and Duenweg, northeast of Joplin.  The area is honeycombed with
underground workings, pits, shafts (open, closed, and collapsed) ,  mine
tailings, waste piles, and ponds holding tailing waters.  Ihe Jasper County
portion of the mining district contains many abandoned underground mine
workings, and the land surface in many parts of the county is covered  with an
estimated 10 million tons of mining wastes.

     Ihe primary sources of contamination at the site are residual metal
sulf ides in abandoned mine workings and tailing piles that were  left uncovered
and unstabilized.  Upon exposure to the atmosphere, these sulf ides mobilize as
dissolved compounds, increasing acidity.  Ihe resulting metal-laden acidic
waters, referred to as acid mine drainage, contaminate ground water and fill
mine shafts and subsidences; when the waters surface through springs,  they
combine with metal-laden runoff and contaminate rivers, creeks,  and lakes.

     Studies conducted by the U.S. Geological Survey  (1977) concluded  that
ground water and surface water are contaminated with lead, cadmium, and zinc.
An estimated 1,500 people obtain drinking water from private wells within
3 miles of the site.

       Conditions at listing (October 1989);  Westlake Landfill covers 200 acres
  in Bridgeton, St. Louis County, Missouri, about 16 miles northwest of downtown
  St.  Louis.  The area is adjacent to prime agricultural land and  is in the
  floodplain of the Missouri River.  Between 1939 and the spring of 1987,
  limestone was quarried on the site.  Starting in 1962, portions  of the
  property were used for landfilling of solid and liquid industrial wastes,
  municipal refuse, and construction debris.  In 1973, Cotter Corp. disposed of
  over 43,000 tons of uranium ore processing residues and soil in  two areas
  covering a total of 16 acres of the Westlake Landfill, according to a Nuclear
  Regulatory Commission (NRC) report published in 1977.

       In 1976, the Missouri Department of Natural Resources (MENR) closed the
  unregulated landfill.  Since then, MCNR has issued several permits for various
  portions of the 200-acre site.  Currently, an operating sanitary landfill has
  a permitted area of 52 acres, and an operating demolition landfill has a
  permitted area of 22 acres.

       Uranium was detected in on-site monitoring wells in tests conducted in
  1985 and 1986 by a consultant to the owner of the landfill.  An  estimated
  60 people obtain drinking water from private wells within 3 miles of the site.

     Conditions at listing (May 1989);  Hevi-Duty Electric Co. operates on
about 125 acres just off U.S.  117 in an industrial-residential area about  2
miles south of Goldsboro, Wayne County, North Carolina.  Since early 1968,
Hevi-Duty, which is owned by General Signal Corp., has manufactured dry and
liquid power transformers on the southern part the property; the northern
two-thirds is leased to local fanners.

     Oil containing PCBs was used in the transformers until the mid 1970s.  In
1979 or 1980, about 1,000 gallons of PC&-containing transformer oil was
spilled from an underground storage tank.  The company removed the soil from
this spill and buried it in an unlined pit on the north end of the property.
In about 1976, PCB-contaminated soil from an underground storage tank area was
removed and buried in a plastic-lined pit under supervision of the North
Carolina Department of Natural Resources and Community Development  (NRCD).
In August 1985, EPA and Hevi-Duty signed a Consent Agreement under which the
company paid a civil penalty of $7,800.

     On January 30, 1986, a cracked pipeline on a tanker truck resulted in a
spill of approximately 1,400 gallons of transformer oil.  According to
Hevi-Duty, this oil, which contained approximately 4 parts per million PCBs,
ran into culverts and an open drainage ditch.  The majority of the oil was
recovered by skimming from the water, then filtered and reused.  The saturated
soil and material used to soak up some of the spill were disposed of in  #1
Wayne County Landfill.  Hevi-Duty also stated that the spill was contained on
its property and did not reach any open water.

     On March 18, 1986, Hevi-Duty reported to NRCD that a crack in an
underground oil line resulted in the loss of approximately 1,500 gallons of
transformer oil.  During a State inspection on May 28, 1986, Hevi-Duty was
cleaning up the spill by pumping water underground, thus flushing the oil  out
of the ground.  A sample of the oil being forced out was collected from a  mud
puddle.  Analysis by the State indicated that it contained 227 parts per
million PCB (Aroclor 1254).  On-site ground water also contained Aroclor 1254.
An estimated 4,600 people obtain drinking water from public wells within
3 miles of the site, the nearest 1,900 feet from the site.

     EPA in 1977 and 1978 and the North Carolina Division of Health Services
in 1985 found elevated levels of Aroclor 1254 in ambient air at the site.  An
estimated 15,000 people live within 4 miles of the site.

     The site drains to the Neuse River approximately 4,650 feet north of  the
plant building.  The river is used for fishing within 3 miles downstream of
the site.

     Hevi-Duty recently hired a contractor to study the environmental status
of the site.

     Conditions at listing  (October 1989);  The  10th Street Site consists of
four contaminated municipal water supply wells and two areas of soil
contamination in the City of Columbus, Platte  County,  Nebraska.  The site
occupies about 18 acres in downtown Columbus on  the  north bank of the Loup
River.  The site boundary is currently delineated by Columbus Municipal Wells
#1, 2, 4, and 11 and by four soil samples.

     These four municipal wells were sampled by  the  Nebraska Department of
Health in June 1984 and December 1988 and by EPA in  April 1987, September
1987, and February 1988.  The  results show from  2.0  parts per billion (ppb)  to
29.0 ppb of 1,1,2-trichloroethylene.  Tetrachloroethylene was detected in
Wells #2 and #4 at levels ranging from 2.0 ppb to 24.7 ppb.  A soil-gas survey
conducted in May 1988 by EPA delineated  a ground water plume with a point
source located in a city parking lot (formerly a scrap metal yard)  about 1,000
feet east of Well #1.  Potential sources of the  soil contamination  are a dry
cleaning facility behind the lot and a laundromat 1,400 feet southwest of the
lot.  Both facilities are or once were identified as small quantity generators
of tetrachloroethylene under Subtitle C  of the Resource Conservation and
Recovery Act.  Both facilities are  within 1,000  feet of the contaminated
wells.

     The municipal wells and private wells within 3  miles of the site provide
drinking water to an estimated 19,300 people;  48 irrigation wells are also in

                                 Mead, Nebraska

     Conditions at listing (October 1989);  The former Nebraska Ordnance Plant
once occupied over 17,000 acres near Head in  a rural part of Saunders County,
35 miles northeast of Lincoln,  Nebraska.   From 1942  to 1956,  the  primary
function of the plant was munitions production at four bomb loading lines for
both World War II and the Korean Conflict.  The plant  was also used for
munitions storage and ammonium nitrate production.   Some  of the operations
used organic solvents.

     Beginning in 1962, portions of the  former plant were sold or transferred
to various other entities.  Today,  the major  production area of the former
plant, approximately 9,000 acres, belongs to  the  University of Nebraska and is
used as an agricultural research station.  The remaining  acreage  is currently
owned by the Nebraska National Guard and numerous private individuals and
corporations.

     The former Nebraska  Ordnance Plant  is being  investigated by  the U.S. Army
Corps of Engineers as part of the Defense Environmental Restoration Program.
The site, however, is not currently owned by  the  Federal  government.  Included
in the Corps investigation are the current university  property, the current
Nebraska National Guard property, and the former  administration area, bomb
booster assembly area,  burning ground/sewage  treatment area,  and  ammonium
nitrate plant.  In a study completed in  April 1989,  the Corps identified areas
of soil contaminated by PCBs and munitions wastes,  including trinitrotoluene
 (TNT) and c^cloraethylenetrimtramine (RDX).   The  Corps also detected TNT, RDX,
and trichloroethylene (TCE) in on-site monitoring wells,  and RDX  and TCE in
off-site drinking water wells.   An estimated  400  persons  obtain drinking water

 over the operation and has used the facility as an airport and aviation safety
 research center.

      In 1984, the New Jersey Department of Environroental Protection (NJDEP)
 contracted for an assessment of pollution sources that could impact the then
 proposed Atlantic City Municipal Well Field, to be located on the north shore
 of the Upper Atlantic City Reservoir within the FAA Technical Center
 boundaries.  This investigation identified five areas as posing a threat to
 the proposed well field:  the Salvage Area (Area 20A), where scrap materials
 and drums of hazardous waste oils and solvents were stored; the Fuel Mist Test
 Facility (Area 27), where jet fuels were sprayed and burned to test the
 antimisting properties of certain fuel additives; the Fire Training Area (Area
 29), where fuel fire testing and fire training exercises were conducted; the
 Avgas Fuel Farm and Photo tab (Area 41), where leaks from underground storage
 tanks, discharge of photographic lab wastes, and spillage of fuels may have
 occurred; and the Abandoned Navy Landfill (Area 56), an area south of the main
 runway used as a landfill by the Navy.

      Hydrogeological studies of the five areas indicated that development of
 the new well field could proceed.  Since then, FAA has informed NJDEP and EPA
 of additional areas that may have an environmental impact.  FAA is conducting
 a remedial investigation/feasibility study (RE/FS) under NJDEP and EPA
 guidance.

      Tetrachloroethylene, 1,1-dichloroethylene, benzene, toluene, and 1,1,1-
 trichloroethane are present in ground water at Areas 2QA,  29, and 56,
 according to a November 1984 report of NJDEP's contractor and initial results
 of FAA's RI/FS.   Elevated levels of cadmium and chromium were found in ground
 water at Area 56.  An estimated 68,000 people obtain drinking water from
 Atlantic City reservoirs, which are fed primarily by the north and south
 branches of Doughty's Mill Stream.  The upper reservoir is on Technical Center
 property, as are nine new Atlantic City production wells.

      Status  (May 1990);  FAA has completed FIs on the original five areas,
"plus" 17 additional areas.  FSs are underway or completed forr-several areas.
 The remedy has been selected for Site D - Jet Fuel Farm.

      EPA and FAA plan to negotiate an Interagency Agreement under CERCIA
 Section 120 to cover the remedial activities to be conducted.

                              Kingston, New Jersey

     Conditions at listing  (June 1988);  The Higgins  Disposal Site covers 38
acres at 121 laurel Avenue  in a rural  area  north of Kingston,  Somerset County,
New Jersey.  For an unknown number of  years, the owner operated an unpermitted
landfill and an unpermitted transfer station on the site.   The owner of this
business owns Higgins Farm, which was  also  proposed for the NFL in June 1988.

     In 1981, as required by  CERCLA Section 103 (c), FMC Corp.  reported to EPA
that in 1974 its Princeton  plant had sent chemical waste containing heavy
metals, organic solvents, and pesticides to the site.   In  October 1982, the
New Jersey Department of Environmental Protection  (NJDEP)  issued an
Administrative Order under  the  State's Solid Waste Management Act requiring
Higgins Disposal to stop accepting and disposing of solid  waste and remove
waste already at the facility.

     On June 26, 1986, NJDEP  sampled soil and water on the property.  Analysis
identified PCBs (Aroclor 1248), tetrachloroethylene,  1,2-dichlorobenzene, and
bis(2-ethylhexyl)phthalate  in on-site  soil.  Aroclor  1248  was also detected in
an on-site pond downgradient  of the landfill.   When full,  the pond spills into
Dirty Brook, which discharges into the Delaware/Raritan Canal.  The canal is
used for boating and fishing.   A fresh water wetland  is 300 feet from the
site.

     Soils on the site are  permeable and ground water shallow, conditions that
facilitate movement of contaminants into ground water.  An estimated 2,000
people depend on private wells  within  3 miles of the  site  as  their sole source
of drinking water.  NJDEP considers Higgins Disposal  a possible source of
local well contamination.

     Status (May 1990):  EPA  is starting a  remedial investigation/feasibility
study to determine the type and extent of contamination at the site and
identify alternatives for remedial action.

                                Lodi, New Jersey

     Conditions at  listing (October 1984);  Ihe Lodi Municipal Well in Lodi,
Bergen  County,  New  Jersey, is contaminated with uranium and its decay
products, according to tests conducted by the State.  In December 1983, the
State closed the well, which was one of nine wells serving about 24,000
people.  Other municipal wells are being used, but they draw from the same
aquifer.  The State is investigating to determine if ground water migrating
from a  nearby thorium-processing facility is contaminating the Lodi Municipal
Well.

     Status (January 1986);  Additional tests of the well water are planned to
determine if the radionuclides present are associated with a naturally-
occurring formation in the area.   The analyses will also include
nonradiological constituents, which are used to help identify the source of
contamination.

     Status (September 1988);  In the spring of 1988, EPA started a remedial
investigation/feasibility study (KE/FS), which should help determine if the
contamination is naturally occurring.

     Status (May 1990);  A draft of the RI/FS report was completed in December
1989.   Additional sampling is planned to determine if the radioactive
contamination is naturally occurring.

                             Colts Neck, New Jersey

     Conditions at listing (Octcter 1984):  The Naval Weapons Station Earle
covers 10,048 acres in Colts Neck, Monmouth County, New Jersey.   Since the
early 1940s, the U.S. Navy has handled, stored, renovated, and transshipped
munitions at the station.  These operations involve preserving and maintaining
anmunition, missile components, and explosives; rendering safe unserviceable
and/or dangerous ammunition and explosives; and providing support to the Fleet
Mine Facility.  The station also conducts or has conducted nonordnance
activities, radiological operations, materials storage, and waste disposal
operations.

     Site A covers 18 waste areas.  Wastes generated in Site A include
ordnance materials, grit and paint, paint scrapings, solvent/paint sludges,
ammonium picrate, lead bullets from small arms ranges,  zinc, lead, titanium,
and small amounts of other constituents.  The  Navy detected contaminants in a
limited number of sediment and surface water samples, but further background
samples are necessary.
                    j
     In 1986, a Navy contractor detected pentachlorophenol in two monitoring
wells in Site A, which overlies the Cohansey Sand, Kirkwood Formation, and
Vincentown Formation aquifers.  All are hydraulically connected,  so  that water
can move among them.  An estimated  620 people  within 3  miles of Site A are
served by these aquifers.  A waste  area is within  200 feet of a wetland where
a branch of Mingamahone Brook originates.

     The station is participating in the Installation Restoration Program,
established in 1978.  Under this program, the  Department of Defense  seeks to
identify, investigate, and clean up contamination  from  hazardous  materials.
The Navy has completed Phase I (records search).   Phase II  (preliminary
survey) is underway.

     Status (July 1985):  EPA and the Navy have agreed  upon a scope  of work
which calls for investigation of 11 of the areas in Site A.

     Status (May 1990);  In October 1989, the  Navy completed a workplan for a
remedial investigation/feasibility  study to determine the type and extent of
contamination at the 11 areas in Site A and identify alternatives for remedial
action.  EPA has reviewed the workplan and sent its comments to the  Navy.

                          LEE ACRES LANDFILL (USDOI)
                            Farmington, New Mexico

     Conditions at listing (June 1988);  The !/=*> Acres Landfill, a Federal
facility site, covers 40 acres of public land in San Juan County southeast  of
Farmington, New Mexico.  The landfill area is about 2,200 feet north and
upgradient of the Lee Acres residential subdivision.  One Giant Industries,
Inc., refinery property is to the southeast.

     On May 1, 1962, the Bureau of land Management  (BIM), part of the U.S.
Department of Interior  (USDOI), leased 20 acres to San Juan County to operate
a county landfill.  In April 1981, the lease was renewed and another 20  acres
were added to the county's lease.

     The landfill consists of an undetermined number of solid waste trenches
and unlined waste lagoons.  At least three of the lagoons may have received a
mixture of liquid wastes, including produced waters from oil and gas fields,
waste oil, spent acids, chlorinated organic solvents, and septic tank wastes,
according to the New Mexico Environmental Improvement Division  (NMEID).   In
1985, NMEID detected chlorinated volatile organic compounds, including
1,1-dichloroethane, 1,1,1-trichloroethane, and 1,2-dichloroethylene, as  well
as benzene, in a lagoon and in a residential well downgradient at the north
end of the Lee Acres subdivision.  An estimated 400 residents use shallow
alluvial ground water within 3 miles of the site for drinking water.

     Lee Acres landfill is near where an arroyo meets the San Juan River,
which is used for recreational activities.  During a heavy rainstorm in  April
1985, a dike of one of the lagoons broke.  Wastes entered the arroyo, posing a
possible threat to the San Juan River.  During the same period, releases of
toxic vapors from the lagoons caused approximately 15 people, including
on-site cleanup workers, to experience difficulty in breathing, severe
headaches, skin rashes, or other symptoms.  Also during that time, the
Governor called in the National Guard to secure the perimeter of the site.
BIM ordered the county to fence the landfill and NMEID hired a contractor to
treat the lagoon contents with ferric chloride to prevent further releases  of
vapors.  San Juan County subsequently filled in the four lagoons.  BIM ordered
the landfill closed and, when the county abandoned it, contracted for fencing.

     In 1985, BIM hired a consultant to study conditions at and near the
landfill.   Subsequently, separate studies were conducted of soil gases,  ground
water hydrology, and ground water quality.  EPA has reviewed the consultant's
reports on the investigation.  In November 1986, BIM arranged for alternative
drinking water supplies for residents of Lee Acres using ground water.   BIM
plans to hire a contractor in 1988 to conduct a remedial investigation to
determine the type and extent of contamination at the site.

     Status  (May 1990);  Later in the year, EPA, NMEID, and BIM plan to  define
the requirements of a remedial investigation/feasibility study.

                                Prewitt, New Mexico

       Conditions at listing  (June 1988) ;  The Prewitt Abandoned Refinery Site
  occupies 75 acres just east of Prewitt on U.S. Highway 66 in McKinley County,
  New Mexico.  Tract A, consisting of 68.2 acres south of the highway,  contains
  the ruins of the refinery,  including waste pits, tank bases, and other rubble
  from equipment that has been removed.  Tract B, consisting of 6.8 acres north
  of the highway, includes two major spill areas and the remains of a pump lift
  station.

       Site operations began  in the  early 1940s and continued for 25 years under
  several different owners and operators, including Petroleum Products  Refining
  Co. , Petroleum Products Refining and Producing Co. , Malco Refineries, New
  Mexico Asphalt and Refining Co. , Malco Asphalt and Refining Co. , and  El Paso
  Natural Gas Products Co.  The Navajo Indian Tribe has owned the property since
  December 1966.

       According to information provided to EPA under CERCIA Section 103 (c) , El
  Paso Natural Gas Products Co. deposited crude refinery wastes at the  site and
  Petroleum Products Refinery and Producing Co. deposited wastes listed as
  hazardous under Subtitle C  of the Resource Conservation and Recovery Act.

       In December 1982, the  New Mexico Environmental Improvement Division
  detected benzene in a nearby private well, and in May 1986 detected benzene
  and xylenes in an on-site well to a depth of 17 feet.  Wells within 3 miles of
  the facility provide water  to a public community water system, a public
  noncommunity water system,  private homes, and livestock.  An estimated 1,600
  people are served by ground water.

       Status (May 1990) ;  The former owners of the site have agreed to reduce
  the immediate hazards posed by the site by constructing a security fence and
  treating well water to remove hydrocarbons.  Water treatment for five homes
  has been completed.

       The former owners entered into an Administrative Order on Consent with
  EPA under CERCIA Section 106 on July 11, 1989.  Under the order, they are
  conducting a remedial investigation/feasibility study (RI/FS)  to determine the
  type and extent of contamination at the site and identify alternatives for
  remedial action.

       During Phase I of the PI monitoring wells were installed and sampled;
  analysis indicates chromium in ground water.  Soil and sediment samples were
  also collected and analyzed.  An Interim Data Summary containing Phase I
  results and a Phase II proposal are to be submitted to EPA during the summer
  of 1990.

                           CARSON RIVER MERCURY SITE
                        Lvxay Churchill Counties, Nevada

     Conditions at listing (October 1989) ;  The Carson River Mercury Site
 (CRMS) consists of: (1) sediments in an approximately 50-mile stretch of the
Carson River in Lyon and Churchill Counties, beginning between Carson City and
Dayton, Nevada, and extending downstream through the lahontan Reservoir to
Stillwater National Wildlife Refuge; and (2) tailing piles associated with the
river.
     In the late 1800s, ore Ttiitv^ from the Comstock Lode near Virginia City
was transported to any of 75 mills, where it was crushed and mixed with
mercury to amalgamate the gold and silver. The availability of water power
made 12 mills along the Carson River in the Brunswick Canyon area become
dominant.

     Mercury-contaminated tailings piles which resulted from the mills have
been found 5 miles up Brunswick Canyon, 3 miles up Six Mile Canyon,  and within
the Carson Plain.  Areas near the Comstock Lode where extensive  mining
occurred, such as in Gold Canyon, may also be major potential sources of
tailings.  Rain transports mercury from the tailing piles to the Carson River,...
where the Nevada Division of Environmental Protection (NDEP) has documented
extensive mercury contamination.  An estimated 7,500 tons of mercury were lost
in the milling process during the 30-year peak of the Comstock Lode, of which
only about 0.5% was later recovered.  Much of the remaining mercury  was
incorporated in the mill tailings.

     Elevated levels of mercury attributed to the piles were detected in the
river from above the Dayton area through the lahontan Reservoir  to the cutoff
of the Stillwater Slough, as well as in Six Mile Canyon Creek.

     Because CRMS extends over such a large area, it potentially affects
several sources of ground water, among them the Dayton Valley Aquifer.  Ground
water in the aquifer is as shallow as 10 feet near the river, and soils are
permeable sands and gravel.  These conditions facilitate movement of
oorrtaminants into ground water.  An estimated 1,400 people obtain drinking
water from wells within 3 miles of the site, the nearest within  2,000 feet.

     Approximately 1,200 acres of food and forage crops are irrigated by the
Carson River between Dayton and the lahontan Reservoir.

     Status fMav 1990) ;  In May 1990, EPA investigated the site  to determine
if an immediate removal action is warranted.  Results are expected shortly.

                               Lisbon, New York

     Conditions at listing (October 1989);  The Sealand Restoration, Inc.,
Site occupies approximately 200 acres south of Pray Road in Lisbon, St.
Lawrence County, New York.  The surrounding area, consisting largely of
farmland and wetlands, is sparsely populated.  In the late 1970s, the company,
also known as Sealand Industrial Services, Inc., disposed of waste oils  and
oil spill debris under a permit issued by the New York State Department  of
Environmental Conservation (NYSDEC).  In addition, wastes were accepted  from
numerous industrial plants in central and northern New York State.  Wastes
were stored or disposed in three on-site facilities:  a drum storage area, a
disposal pit, and a land spreading area.  In 1980, NYSDEC ordered the company
to stop waste disposal activities.

     In 1980, the New York State Department of Health (NYSDH) found low  levels
of cadmium in residential wells near the site.  Under a Consent Order
Agreement in 1981, Sealand Restoration agreed to clean up the site; however,
the firm was subsequently cited for noncompliance.  The site has been referred
to the State Attorney General.  According to NYSDEC, St. Lawrence County
received a $100,000 Local Assistance Grant in 1984 from the New York State
legislature to perform limited cleanup at the site.  The county removed  133
drums left on the surface, along with 60 full or partially full buried drums,
42 empty buried drums, and 150 cubic yards of contaminated soil.  These  wastes
were transported to a hazardous waste facility regulated under Subtitle  C  of
the Resource Conservation and Recovery Act.

     Acetone, trichloroethane, toluene, benzene, and trichloroethylene were
present in on-site monitoring wells downgradient of the landfill, according  to
tests conducted in 1986-87 by a consultant to NYSDEC.  An estimated 1,100
people obtain drinking water from private wells within 3 miles of the site,
one of which is on the site.  The on-site well has been taken out of service.

     Trichloroethane and tetrachloroethylene were detected in surface water
downhill from the site in tests conducted by the State  (1980) and EPA  (1985).
A fresh water wetland lies within and adjacent to the site.  The area is used
for recreational activities.

     NYSDEC has conducted a  study to determine the type and extent of
contamination at the  site.   The study determined that surface soils in the
land spreading area contain  low levels of PCBs and heavy metals, and that
contaminants may have migrated downward  in  soils beneath where the drums had
been stacked.  The shallow aquifer is contaminated downgradient of the
disposal pit.  Possible  interconnection with a deeper aquifer must be
assessed.

     Status  (May 1990);  In  March  1990, NYSDEC excavated approximately 800
tons of contaminated  soils and 1,500  drums  of wastes and transported the
materials to a hazardous waste disposal  facility regulated under Subtitle  C of
the Resource Conservation and Recovery Act.  The excavated area remains  to be
seeded and graded.

                               Romulus, New York

     Conditions at listing (July 1989):  The  Seneca Army  Depot encompasses
more than 10,000 acres  in Seneca County, New  York.  It lies between Cayuga and
Seneca TaV^g in the Finger lakes region and abuts the  town of Romulus.  The
Army has  stored and disposed of  military explosives at the facility since its
inception in 1941.

     Seneca Army Depot  is participating in  the Installation Restoration
Program  (IRP), established in  1978.   Under  this program,  the  Department of
Defense seeks to identify, investigate, and clean up contemn nation  from
hazardous materials.

     During preliminary investigations, the Army identified a number of
potentially contaminated areas,  including an  unlined 13-acre  landfill in  the
west-central portion  of the depot, where solid waste and  incinerator ash  were
disposed  of intermittently for 30 years during 1941-79; two incinerator pits
adjacent  to the landfill, where  refuse was  burned at least once a week during
1941-74;  a 90-acre open burning/detonation  area in  the northwest  portion  of
the depot, where explosives and  related wastes have been  burned and detonated
during the past 30 years; and  the APE-1236  Deactivation Furnace in  the east-
central portion of the  depot,  where  small arms are  destroyed.

     Monitoring wells on the depot downgradient of  the old landfill contain
elevated  concentrations of trans-l,2-dichloroethylene, and trichloroethylene,
according to tests conducted in  1987 by an  Army contractor.  An estimated
1,350 people obtain drinking water from private wells  within  3 miles of the

                                  Dover, Ohio

     Conditions at listing (June 1988);  The Reilly Tar &  Chemical Corp. Site
covers 4 acres in Dover, Tuscarawas County, Ohio.   The  facility/ which
operated during 1932-56, included a coking plant and  foundry built on top of
an area that had been filled with slag.  The operations involved coal tar,
including creosote wastes, according  to information Reilly provided to EPA.

     Soil and monitoring wells installed by EPA show  high  levels of creosote
constituents, including naphthalene,  fluoranthene,  pyrene, 2-methyl-
naphthalene, and phenanthrene, according to EPA tests conducted in 1985.

     The site is located on the sand  and gravel deposits of the Tuscarawas
River basin.  The aquifer in the deposits is the sole source of drinking water
for about 28,700 people served by the municipal water systems of Dover and New
Philadelphia.  An additional 4,000 people obtain drinking  water from private
wells within 3 miles of the site.

     The site is not completely fenced, making it possible for people and
animals to come into direct contact with hazardous  substances.

     The property is presently owned  by Shenango Foundry and is inactive.

     Conditions at listing  (October 1989); The Union Pacific Railroad Co.  Tie-
Treating Plant covers 83 acres in a ™iv«=ri commercial and residential area just
south of the Columbia River in the City of The Dalles, Wasco County,  Oregon.
Union Pacific owned the wood treatment facility  from 1926 to late  1987,  when
equipment and structures were purchased by Kerr-MoGee Chemical Corp.; however,
Union Pacific retained ownership of the land and responsibility  for all  pre-
1987 contamination of facility soil and ground water.  The plant primarily
treated railroad ties for Union Pacific, but also treated wood for other
commercial users across the United States.  From 1959 to November  1987,  J. H.
Baxter Co. operated the plant for Union Pacific.

     The facility treated wood with ammoniacal copper arsenate,  creosote,  a
creosote/fuel oil mixture,  and pentachlorophenol.  Spills of treatment
solutions on-site and waste water ponds no longer in use are thought to  be the
main source of contamination of soil and ground  water.  Improvements in  the
waste water treatment system allow the site to operate as a zero discharge
facility.

     In 1984, Union Pacific began a comprehensive investigation  of soil  and
ground water at the site.   Creosote components,  pentachlorophenol, fuel  oil,
ammonia, volatile organic compounds  (VOCs), and  arsenic are the  major
contaminants found in soil  and ground water at the site.  Contamination  by
arsenic and VOCs is greatest in the shallow and  intermediate aquifers beneath
the site.  Organic contaminants, including phenanthrene and naphthalene, have
been detected in the two deep confined aquifers  beneath the site.   Ground
water is used by over 11,000 people within 3 miles of the site.  The Dalles
has increased its monitoring of the municipal supply wells.

     In May 1989, Union Pacific signed a Consent Order with the  Oregon
Department of Environmental Quality  (DEQ) and agreed to undertake  a remedial
investigation/feasibility study  (RI/FS) to determine the type and  extent of
contamination at the site and identify alternatives for remedial action.  The
RI/FS is scheduled to be completed by mid-1991.

     Status  (May 1990):  DEQ approved Union Pacific's workplan  for the RI/FS
in January 1990.  The investigation is now underway.

trichloroethylene (TCE) in 23 tap water samples.  The water supplies of
approximately 170 homes, apartments, and businesses in Dublin have been
impacted.

     The highest TCE concentrations (up to 10,000 parts per billion) were
found in a well on property that has been occupied by several industrial
operations over the past 50 years.  EPA considers this property, located at
120 Mill Street in Dublin Borough, to be the likely source of the
contaminants.  According to EPA's report on its search for parties potentially
responsible for wastes associated with the site, the companies that operated
on-site include Dublin Hosiery Mills, Inc.; Home Window Co. of Pennsylvania,
Inc.; Kbllsman Motor Corp.; and Dudley Sports Division of Athlone Industries,
Inc.

     John H. Thompson acquired the property in January 1986 and is using the
main building to restore antique race cars.  Laboratory Testing, Inc., has
leased part of the property since May 1986.

     The sole source of drinking water in the area is the Brunswick and
Lockatong Formations, which are hydraulically connected, permitting water  to
move between them.  An estimated 10,100 people obtain drinking water  from
public and private wells within 3 miles of the site.

     On June 29, 1987, Mr. Thompson entered into a Consent Order with EPA
under CERdA Section 106 (a).  Under the order, Mr. Thompson is providing water
treatment systems or bottled water to persons with contaminated wells and  is
periodically sampling wells in the area.  He has also been cooperating with
requests from the Pennsylvania Department of Environmental Resources  (PA DER)
to study soil and ground water at the site.

     Status  (May 1990);  In October 1989, the PA DER  approved a plan  submitted
by Sequa Corp.  (which now owns Kbllsman Motor Corp.) to investigate the source
of TCE contamination.  PA DER is reviewing results of the investigation.

     In January 1990, a fire water tower contaminated with TCE leaked.  A
carbon system is being installed to treat the contamination.

     In March 1990, PA DER conditionally approved Sequa's plan to pump
contaminated ground water to the surface, treat it to remove the
contamination, and discharge the treated water to the public sewer system.

     EPA plans to investigate the possibility that parties potentially
responsible for wastes associated with the site will  conduct a remedial
investigation/feasibility study to determine the type and extent of
contamination and identify alternatives for remedial  action.

                                OHIO RIVER PARK
                          Neville Island,  Pennsylvania

     Conditions  at listing f October 1989):  The 61-acre Ohio River Park Site
is on the western end of Neville  Island in Allegheny County, Pennsylvania.  It
is almost completely surrounded by  the Ohio River.  The site was owned by
Pittsburgh Coke  & Iron Co.  [later named Pittsburgh Coke & Chemical Co. (PC&C) ]
from the 1920s until 1970, when the property was transferred to a wholly owned
subsidiary, Neville land Co.   In  1976, the property was donated to the county.
According to EPA, from the 1930s  until the mid-1950s, the site served as a
landfill for municipal wastes from  Neville Township.  From 1952 until 1965,
trenches were dug on-site  to  dispose PC&C's wastes such as coking sludges
(which often contain benzene  and  toluene), cement production wastes, and
pesticides.  Other industrial wastes such as plant demolition materials and
slag were also disposed on-site.

     In 1978, Allegheny County began developing the site as a park but stopped
construction after industrial waste was found.  In 1979, an Allegheny County
consultant reported that on-site  ground water and soil contained contaminants
such as benzene,  toluene,  2,4-dichlorophenoxy acetic acid (2,4-D), 2,4,6-
trichlorophenol,  and 2,4-dichlorophenol.  The consultant concluded that a
public health threat existed  at the site. " The land was then returned to
Neville Land Co.

     Routine monitoring by the county's consultant consistently detects
benzene and toluene in ground water.

     Neville Land hired a  consultant to further evaluate the site.  The work
has included installation  of  27 multilevel wells, extensive sampling,
excavation of test pits, analysis of aerial photographs, and toxicological and
hydrogeological  evaluations.   Limited remedial actions were taken, including
the removal of a container of almost pure 2,4-D and the surrounding soil,
stabilization of a section of shoreline where sulfur-containing waste was
exposed, installation of a fence, and posting of warning signs.

     An estimated 40,000 people obtain drinking water from public and private
wells within 3 miles of the site.   Seven  municipal wells are 600 to 1,200  feet
from the site.

     An outfall  from a storm  sewer  system which drains a small portion of  the
northeastern quadrant of the  site is contaminated with 2,4-dichlorophenol,
2,4,6-trichlorophenol, 2,4-D, and 2,4,5-T, according to tests Allegheny
County's consultant conducted in  1979 and 1981.  This outfall discharges to
the Ohio River.   Sewickley Water  Works draws water from the river 1.7 miles
downstream from  the contaminated  outfall.  The intake provides drinking water
to an estimated  8,000 people.

     Status  (May 1990);  EPA  plans  to investigate the possibility that Neville
Land Co. will conduct a remedial  investigation/feasibility study to determine
the type and extent of contamination at the site and identify alternatives for
remedial action.

                              Paoli, Pennsylvania

     Conditions at listing (January 1987);  The Paoli Rail Yard covers about
30 acres in Paoli, Chester County, Pennsylvania.  The yard consists of an
electric train repair facility owned by Amtrak and operated by the
Southeastern Pennsylvania Transportation Authority (SEPTA).  Routine
maintenance and repair of railroad cars involve PCB-oontaining electrical
equipment.  The yard is surrounded on three sides by residential  comraunities
and on the fourth by commercial facilities.  Until February 1986, people  used
the yard as a shortcut to the station and commercial properties.

     In the late 1970s, both EPA and the Pennsylvania Department  of
Environmental Resources (PA DER) inspected the Paoli Rail Yard.   This
inspection, coupled with subsequent State investigations, led  PA  DER  to issue
an order in 1979 requiring Amtrak, SEPTA, and  Conrail to determine the extent
of contamination and correct any problem areas.  The companies took actions
primarily involving collection of samples, some cleanup, and further  study.

     In November 1985, analyses of samples taken in  July 1984  by  a consultant
to the companies were provided to EPA.  They indicated  a severe PCB problem,
with soil contamination as high as 3 percent and to  depths of  up  to 3 feet.

     In December 1985, a team consisting of staff from  EPA, the U.S.  Agency
for Toxic Substances and Disease Registry, and the State Health Department
made a preliminary assessment to verify the existing sample results and
identify areas of most concern.

     On February 25, 1986, EPA filed a complaint under  the Toxic  Substances
Control Act, CERCIA, and the Resource Conservation and  Recovery Act.   The
complaint sought an  order requiring the three  companies to limit  access to the
yard, control migration of PCBs, conduct sampling and analysis, and take
measures to clean up the yard and protect worker safety.  A security  fence was
installed as a preliminary measure.

     In June 1986, a second agreement was reached requiring the companies to
develop a plan to control erosion, sedimentation, and contaminated ground
water.  In the fall  of 1986, EPA used $600,000 in CERCIA emergency funds  to
remove contaminated  soil in nearby areas and control erosion on the yard.

     Status  (July 1988):  Under a May 1987 agreement with EPA, the three
companies are conducting a remedial investigation/feasibility  study  (RI/FS)  to
determine the extent of contamination.  Under  a separate agreement, SEPTA has
taken measures to protect workers in the repair shop at a cost of $2  million.
In October 1987, the three companies agreed to conduct  extensive  soil sampling
in the surrounding neighborhoods, and in January 1988,  EPA's emergency program
began additional measures to stabilize the yard and  nearby Central Avenue.

     After this site was proposed in January 1987, additional  technical
information became available.  Hence, EPA is reproposing the site.

     Status  (Mav 1990);  The three companies have completed most  of the field
work for the RI.  RI sampling was extended to  investigate oil  contamination of
ground water discovered in 1989.  The RI  report is expected shortly.

                          Salford Township,  Pennsylvania

      Conditions at listing (January 1987);  The Salford Quarry covers
 approximately 3 acres on Quarry Road in lower Salford Township, Montgomery
 County, Pennsylvania.  The site was quarried for stone/aggregate for an
 unknown period prior to 1963.  In 1963, American Clean Tile Co.,  which is
 owned  by National  Gypsum Co., purchased the abandoned quarry, and until 1980
 used the site for  disposal of its wastes.   Included were waste tiles, unfused
 tile slurry,  and other production wastes.   In 1980, the State received
 complaints that tanks were buried on the site.  In 1981, American Clean
 discovered two 10,000-gallon tanks.  According to tests conducted by the
 company and the Pennsylvania Department of Environmental Resources (PA DER),
 the tanks  hold tile slurry containing boron and fuel oil.  After the company
 pumped out the oil,  the site was officially closed in May 1982 in accordance
 with a plan approved by PA DER.  Closure involved capping with soil, grading,
 and revegetating.

      The downgradient monitoring well on-site is contaminated with boron,
 according  to  EPA analyses.  An estimated 54,000 people draw drinking water
 from public  (North Perm  Water Authority)  and private wells within 3 miles of
 the site.  A  private well 650 feet from the site is contaminated with boron,
 according  to  EPA analyses.

      Status  (May 1990):   Wider a Consent Agreement signed with EPA in 1988,
 National Gypsum Co.  has prepared final workplans for a remedial investigation
 site operation plan and for a remedial investigation/ feasibility study to
 determine  the type and extent of contamination at the site and identify
 alternatives  for remedial action.   EPA is  reviewing the workplans.

                            Tobyhanna, Pennsylvania

     Condition at listing (July 1989):  Tobyhanna Army  Depot covers 1,293
acres in Tobyhanna, Monroe County, in the Pocono Mountains of northeastern
Pennsylvania.  Military operations started on the site  in 1913.   The facility
assumed its present name in August 1962.  The depot's primary mission is to
provide maintenance and supply support to the Army.  The depot includes 131
buildings.  Metal refinishing, electronic fabrication,  electroplating,  and
degreasing operations are conducted on-site.  All types of depot wastes,
including plating wastes, paints, solvents, sewage treatment sludge,  and solid
wastes, were disposed of on-site prior to 1975.

     Tobyhanna Army Depot is participating  in the Installation Restoration
Program (IRP), established in 1978.  Under this program, the Department of
Defense seeks to identify, investigate, and clean up contamination from
hazardous materials.  IRP investigations have focused on two areas in the
southeastern section of the depot:  Area B, which consists primarily of a
swale/trench containing rusted drum fragments, and Area A, in which pits
contain volatile organic compounds and polynuclear aromatic hydrocarbons.

     IRP investigations conducted in the southeastern section in 1981 and 1986
found trichloroethylene  (TCE) in  on-site monitoring  wells, and  1,2-
dichloroethylene, TCE, and tetrachloroethylene in on-site and off-site water
supply wells.  An estimated 4,300 people obtain drinking water  from depot and
private wells within 3 miles of hazardous substances on the depot.

     The Army is conducting a remedial investigation and an endangerment
assessment for the portion of the site contaminating the Village of
Tobyhanna's water supply.  Future studies are planned for the remainder of the
site.

     Status  (May 1990);  The Army is preparing to fill  in data  gaps in the
investigations of Areas A and B.  A treatability study  is underway to
determine how to clean up soil contamination.  Also, the Army is providing
bottled water to people whose wells were contaminated and will  soon extend the
depot's water line to provide a permanent water supply.

                              Sharon, Pennsylvania

     Conditions at listing (June 1988);    Westinghouse Electric Corp.  produced
and repaired transformers during 1922-84  on a 50-acre site at 409 Sharpsville
Avenue  in a heavily industrialized area of Sharon, Mercer County,
Pennsylvania.   During 1936-76, Westinghouse used PCBs as a conducting fluid in
some of the transformers.  In 1976, 48,000 gallons of PCBs and 15,000 gallons
of organic  solvents were removed from the site and incinerated.  PCBs were
spilled in  certain areas during  routine operations.   In  1984,  at least 6,000
gallons of  solvents and oil leaked from an underground tank and became
contaminated with  PCBs in the soil.

     In November 1985, EPA detected PCB 1260 at  two  of the four points where
the plant discharges waste water to the Shenango River,  which is 0.5 mile to
the east.   The company had a permit for the discharges under the National
Pollutant Discharge Elimination  System  (NPDES).   The Shenango Valley Water Co.
provides  drinking water to an estimated 75,000 people from an intake
approximately  1,600 feet downstream of the plant's discharge points.  The
Pennsylvania Department of Environmental  Resources  (PA DER) detected PCBs in
river sediments between the site and the  intake.

     Tests  conducted in 1986 by  a Westinghouse consultant detected PCBs,
1,2,4-trichlorobenzene, and methyl ethyl  ketone  in on-site ground water.

     In April  1985, PA DER issued Westinghouse an Administrative Order under
the State's Clean  Streams Law and Solid Waste Management Act.   Under the
order,  Westinghouse has conducted a limited study of subsurface conditions and
submitted a cleanup plan to PA DER.

     This facility obtained Interim Status under Subtitle C of the Resource
Conservation and Recovery Act (RCRA)  when it filed a Notification of Hazardous
Waste Activity and Part A of a permit application to treat, store, or dispose
of hazardous waste.  later, it withdrew its Part A and converted to generator-
only status with EPA or State approval.   Hence,  it satisfies a component of
EPA's NPL/RCRA policy.

     Status May 1990:  On September 21, 1988, Westinghouse and PA DER signed a
Consent Order  and  Agreement under which Westinghouse is  conducting a remedial
investigation/feasibility study to determine the type and extent of
contamination  at the site and identify alternatives  for  remedial action.
Field work  started in March 1990.

                          Simpsonville,  South Carolina

     Conditions at listing  (October  1989);  Para-Chem Southern, Inc.,  has
manufactured organic solvents and adhesives on a  100-acre site near
Simpsonville, Greenville County, South  Carolina,  since 1965.   The area is
rural and sparsely populated.

     During 1975-1979, 800 to 1,600  drums of  organic and inorganic wastes were
buried  in unlined trenches in three  parts of  the  site,  according to
information the company  provided to  EPA as required by CERCLA Section 103 (c).
Waste water from the plant was disposed of in two unlined lagoons until
November 1984,  when  the  South Carolina  Department of Health and Environmental
Control (SCDHEC) issued  Para-Chem a  permit under  the National Pollutant
Discharge Elimination  System (NPDES).

     In October 1985,  SCDHEC found manganese  and  several organic chemicals,
including chloroform,  carbon tetrachloride, and 1,1,1-trichloroethane, in on-
site ground water; carbon tetrachloride and 1,1,2-trichloroethane in off-site
ground  water and surface water; and  arsenic,  barium,  manganese, nickel, and
zinc in sediments in on-site surface water. 1,1-Dichloroethylene, 1,1-
dichloroethane, 1,1,1-trichloroethane,  2-butanone,  and tetrahydrofuran were
found in on-site monitoring wells in tests conducted in July  1987 by a Para-
Chem consultant.  An estimated 1,500 people obtain  drinking water from private
wells within 3  miles of  the site, the nearest within 1 mile.

     SCDHEC placed the company under a  joint  waste  water/hazardous waste
Consent Order in February 1985, and  in  January 1986 fined the company for
violating its NPDES  permit.  The order  also addressed the buried drums and a
spill of 3,500  gallons of ethylacrylate in January  1985.  Since 1986,  the
company has been fined twice for failure  to meet  its NPDES permit.

     Under  the  Consent Order, Para-Chem excavated soil from the drum burial
areas and filled in  the  two lagoons.  The soil was  moved to a hazardous waste
facility regulated under Subtitle C  of  the Resource Conservation and Recovery
Act.  The action was completed in 1987.   During the action, ground water
contamination consistent with earlier analyses was  detected.

     Status (May 1990);  EPA is considering various alternatives for the site.

                           Rapid City, South Dakota

     Conditions at listing (October 1989);  Ellsworth Air Force Base covers
4,858 acres in Meade and Pennington Counties, South Dakota, approximately
6 miles northeast of Rapid City and 1.4 miles north of Box Elder.  The base is
bordered by open land on three sides, and residential/commercial areas on the
fourth.

     Established in 1942, Ellsworth is now the base for the 44th Strategic
Missile Wing of the Strategic Air Command (SAC).  Base operations generally
support the SAC mission and include runways, airfield operations, fire
protection training, industrial and maintenance shops, a base hospital,
grounds maintenance, a photo lab, and housing facilities.  These operations
generate a variety of chlorinated solvents, solvent-contaminated waste oils,
pesticides, and other hazardous wastes that were deposited at various
locations on the base.

     Ellsworth Air Force Base is  participating in the Installation Restoration
Program (IRP), established in 1978.  Wider this program, the Department of
Defense seeks to identify, investigate, and clean up contamination from
hazardous materials.  IRP has identified  17 potentially contaminated areas—
13 on-base, 4 off-base.  EPA evaluated four of these areas—three unlined
landfills and the Fire Protection Training Area burn pit.

     Qn-site shallow monitoring wells downgradient from the landfills and burn
pit are contaminated with 1,1-dichloroethane, 1,2-dichloroethylene,
trichloroethylene, arsenic, and chromium, according to tests conducted in
1987-88 by the Army Corps of Engineers.   An estimated 1,600 people obtain
drinking water from wells within  3 miles  of the base, the nearest less than
1 mile downgradient of the burn pit and two of the landfills.

     Status  (May 1990);  Ellsworth has completed portions of a remedial

                           Sioux Falls,  South  Dakota

     Conditions at listing  (October 1989);  The Williams Pipe Line Go.
Disposal Pit is in the northeast corner of the company's 12th Street terminal
in Sioux Falls, Minnehaha County, South Dakota.  The terminal is bordered on
the south by 12th  Street  (State Highway 42), on the west by Valley View Road
and a residential  development,  on the north by the Chicago & Northwestern
Railroad tracks, and on the  east by Marion Road.  The site is 2 miles west of
the Big Sioux River and Skunk River.

     The unlined pit measures 9 feet  by 9  feet and is about 7 feet deep.  For
a number of years  prior to 1986, a variety of  wastes generated by the terminal
were dumped into the pit.  Until the  1970s, wastes were burned periodically.
The pit is now dry and covered  with a plastic  sheet.

     Tests conducted in 1986-87 by EPA show that sediment in the pit contains
barium, beryllium, chromium, copper,  iron,  lead, zinc,  benzene, toluene,
xylene, polynuclear aromatic hydrocarbons,  and pesticides.

     Ground water  near the pit  is contaminated with 4,4'-ODD, 4,4'-DDT, gamma-

              MURRAY-OHIO MANUFACTURING CO. (HORSESHOE BEND DUMP)
                            Lawrenceburg, Tennessee

     Conditions at listing (June 1988);  The Murray-Ohio Manufacturing Co.
(Horseshoe Bend Dump) Site covers 12 acres on Horseshoe Bend, a sharp, narrow
bend of Shoal Creek in Lawrence County, Tennessee, approximately  1.5 miles
southwest of Lawrenceburg.  The site is in the extreme northern tip of the
bend on low-lying terrain immediately adjacent to Shoal Creek.  Prior  to about
1956, a hydroelectric plant owned by the City of Lawrenceburg operated on the
site.  During 1956-63, the city owned and operated the site as  a  municipal
landfill.

     The primary source of hazardous waste at the site is Murray-Ohio
Manufacturing Co..  Company records indicate that, beginning about 1956, paint
sludge and other wastes were poured into shallow pits at the dump.  The  pits
were partially filled after the liquid portion of the waste had soaked into
the ground.  Drummed waste was also placed in pits.  In the spring of  1963,  a
large fire at the site reportedly produced toxic smoke and fumes,  which  caused
eye and respiratory irritation.  Also, fish were killed in Shoal  Creek during
or shortly after the fire.  The site was apparently abandoned after the  fire
and has since been used only for occasional dumping of household  trash.  In
recent years, access to the area has been restricted by a landowner across
whose property the road to the site passes.

     In an inspection in 1983, the Tennessee Division of Solid  Waste
Management found partially buried leaking drums at the site.

     Soils on the site contain elevated levels of chromium, lead, and  zinc,
according to tests conducted by Murray-Ohio Manufacturing in 1984.  Soils are
highly permeable; springs, caves, and sinkholes are plentiful in  this  area;
and ground water is shallow (4 feet).  These conditions facilitate movement of
contaminants into ground water.  The City of lŁiwrenceburg obtains part of its
water supply from a large spring about 0.9 mile northeast of the  site.  This
water is also supplied to the Fall River Utility District.  An  estimated
19,000 people obtain drinking water from wells and springs within 3 miles of
the site.

     Within 3 miles downstream of the dump, Shoal Creek is used for fishing,
water-contact recreation, and industrial process cooling water.

     The site is 2 miles from the "Murray-Ohio Dump," which was placed on the
NPL in September 1983.

     Status  (Mav 1990);  Under a Consent Agreement entered into in March 1990
with EPA, Murray-Ohio and the City of Lawrenceburg will conduct a remedial
investigation/feasibility study to determine the type and extent  of
contamination at the site and identify alternatives for remedial  action.

                               Fort Worth, Texas

     Conditions at listing (October 1984);  Air Force Plant #4 occupies
approximately 650 acres in Fort Worth, Tarrant County, Texas.  General
Dynamics operates the plant, which manufactures aircraft for the Air Force.
In November 1982, the Air Force and General Dynamics notified EPA that
hazardous substances were found in a storm water outfall that drains into a
creek on the west side of the plant.  Under Air Force supervision, General
Dynamics constructed a french drain and a collection basin at the outfall.
Since that time, leachate from the drain and outfall has been collected,
stored, and disposed of in an EPA-regulated disposal facility-  In 1983, the
Air Force removed 21,300 cubic yards of contaminated soil from closed waste
pits and disposed of the soil at a regulated disposal facility.

     The Air Force has drilled numerous test holes and 97 monitoring wells  in
and around 20 areas, which cover a total of about 8 acres.  Many of the areas
have contained hazardous substances.  Analyses of the wells indicate that
ground water in the upper zone under the site is contaminated with organic
chemicals and heavy metals.  Several deeper wells were drilled at the site
into the Paluxy aquifer, the source of drinking water for nearby residents,
including White Settlement  (population 13,420).  Two wells have been found  to
be contaminated by trans-l,2-dichloroethylene and trichloroethylene.

     The plant is participating in the Installation Restoration Program,
established in 1978.  Under this program, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous materials.

     At the request of the Air Force, EPA has further investigated off-site
areas, including several White Settlement wells, sediment in the creek and
Lake Worth, and selected residential wells near the site.  EPA drilled four
monitoring wells near the plant area.  The White Settlement municipal wells
and the four EPA wells are monitored on a quarterly basis by EPA.

     In November 1980, the facility received Interim Status under the Resource
Conservation and Recovery Act  (RCRA) when General Dynamics and the Air Force
filed Part A of a permit application to treat and dispose of hazardous wastes.

     Status  (July  1987);  This site is being reproposed to be consistent with
EPA's recently proposed policy for placing on the NPL sites located on
Federally-owned facilities that are subject to the corrective action
authorities of Subtitle C of PCRA.  EPA  is soliciting comments on the Hazard
Ranking System score for the sites, which includes areas subject to RCRA
Subtitle C corrective action authorities.

     Status  (July  1990);  EPA is placing this site on the NPL.

     The Air- Force is conducting a remedial investigation/feasibility study to
determine the type and extent of oontainination at the entire base and identify
.alternatives for remedial action.  EPA, the Texas Water Commission, and  the
Air Force are negotiating an  Interagency Agreement under CERCLA Section  120 to
cover activities at approximately 21  areas on the base.

                                 Karnack, Texas

     Conditions at listing (July 1989);   Longhorn Army Ammunition  Plant (IAAP)
covers 8,490  acres between State Highway 43  and Caddo Lake in Karnack,
Harrison County,  Texas.   The area is primarily rural.  Established in 1941,
IAAP has been operated since 1956 by Thiokol Corp.   Its primary mission is to
load, assemble,  and pack solid propellant rocket motors and pyrotechnic and
illuminating  ammunition.   Until  about 1984,  production wastes were washed into
ponds or burned in landfills. At present, explosive residues,  waste water
treatment sludge from explosives,  and brine  sludge are burned in an
incineration  area.  Liquid and solid wastes  are new  placed in drums and stored
in separate areas until disposal is arranged.

     IAAP is  participating in the Installation Restoration Program (IRP),
established in 1978.   Under this program,  the Department  of Defense seeks to
identify, investigate, and clean up contamination from hazardous materials.
Under IRP, the Army has identified 11 contaminated or potentially  contaminated
areas.  Among them are the Active Burning Grounds, where  flammable wastes have
been burned since the early 1950s; the Unlined Evaporation Pond (in the Active
Burning Grounds),  into which an  estimated 16,000 gallons  per  day of waste
containing arsenic, barium, chromium, lead,  zinc, and organic nitrogen
compounds were discharged during 1972-84;  the Old Landfill, where
trinitrotoluene (TNT)  wastes were disposed of during 1942-44; the  Former TNT
Production Area;  and  the Ground  Signal Test  Area and South Test Area, where
various rocket motors and ammunition are tested.

     A 1984 IRP study reports barium, chromium,  and  lead  in sediments from the
Unlined Evaporation Pond,  and barium in  soil from the Old landfill.  The study
also found that arsenic,  barium, chromium, lead,  zinc, 1,3-dinitrobenzene, and
1,3,5-trinitrobenzene are present in on-site monitoring wells near the Active
Burning Grounds.  An  estimated 1,900 people  obtain drinking water  from wells
within 3 miles of hazardous substances on IAAP.   The nearest  well  is 500 feet
form IAAP1 s northern  boundary.

     Dinitrobenzene,  2,4,6-trinitrotoluene,  nitrobenzene,  2,4-dinitrobenzene,
and 2,6-dinitrotoluene are present in surface waters,  according to the 1984
IRP study.  The  contaminants originate from  at least two  areas  in  IAAP:   the
Old Landfill  and the  Former TNT  Production Area.  Harrison Bayou flows east  of
the Old landfill; the Production Area is drained by  Goose Prairie  Creek and
Central Creek.   Goose Prairie Creek,  Central Creek,  and Harrison Bayou drain
into Caddo Lake.  Caddo Lake, a  part of  the  Big Cypress Bayou,  which flows
into the Red  River, is used for  recreational activities.

                               Texas City, Texas

     Conditions at listing  (June 1988):  The Tex-Tin Corp. Site covers
approximately 150 acres in an industrial area at the intersection of Highway
146 and FM 519 in Texas City, Galveston County, Texas.  During World War II,
the Federal Government constructed a tin smelter on the site.   Wah Chang Corp.
bought the site after the war and sold it in 1970 to Gulf Chemical and
Metallurgical Co., which changed the name to Tex-Tin Corp. in  1985.

     EPA and the Texas Water Commission have been investigating the  site since
it was identified in a 1978 survey of waste disposal sites by  the U.S.
Congress (the "Ekhardt Report").

     Hazardous waste units at the site include:  five waste water treatment
ponds, gypsum slurry ponds, a pond containing about 19 million gallons of
highly acidic ferric chloride waste, an area of iron sludge contaminated with
amiben (a pesticide), tin slag piles,  about 20,000 drums of spent catalyst,
and a landfill containing radioactive waste.

     Monitoring wells near the acidic  ferric chloride pond are contaminated
with copper and tin, according to tests conducted by Gulf Chemical and
Metallurgical in 1980.

     In October 1986, the Texas Air Control Board detected tin in the air
downwind of the smelter at the property boundary.  An estimated 21,700 people
live within 4 miles of the site.

     Surface water within 3 miles downstream of the site is an important
source of shellfish and is used for recreational activities.   A coastal
wetland is within 2 miles of the site.

     In 1985, EPA issued an Administrative Order under the Clean Water Act
charging Tex-Tin with violating its permit issued under the National Pollutant
Discharge Elimination System.  Tex-Tin has undertaken some interim measures to
come into compliance with the order.

     Status (May 1990);  In September  1989, EPA detected copper in the air
downwind of the smelter.

     In December 1989, EPA issued a unilateral order requiring Tex-Tin to
repair and add to the perimeter fence  and post warning signs.   On March 30,
1990, EPA, Tex-Tin, and Amoco Chemical Co. (part owner of the  old Tex-Tin
property) entered into an Administrative Order on Consent under which the two
companies will, with EPA oversight, conduct a remedial investigation/
feasibility study to determine the type and extent of contamination  at the
site and identify alternatives for remedial action.  Field work is expected to
begin in the fall of 1990.

                                 Midvale, Utah

     Conditions at listing (October  1984);  Sharon Steel  Corp. owns a mill
tailings site in Midvale, Salt lake  County, Utah.  Midvale (population 10,000)
is a part of the Salt Lake City metropolitan area  (population 936,000).
Metals were milled on the 260-acre site  from about 1910 to 1971.
Approximately 10 million tons of mill tailings containing high concentrations
of lead, arsenic, cadmium, chromium, copper, and zinc remain on the site.
Sharon Steel purchased the site in 1979.

     This site was first proposed as "Sharon Steel Corp.  (Midvale Smelter)."

     Issues of concern at the site include air contamination from wind-blown
tailings,  tailings washing into the  Jordan River, and impacts on  ground water.
Ground water samples have shown contamination with arsenic and lead, according
to analyses conducted by the  State and Sharon Steel. About 500,000 people
depend on wells within 3 miles of the site as a source  of drinking water.

     Status  (January 1986);   This site is included in a multisite cooperative
agreement between EPA and the State  of Utah.  The State has a contractor to
perform a remedial investigation/feasibility study  (RI/FS)  to determine the
type and extent of contamination at  the  site and identify alternatives for
remedial action.

     Status  (May 1990):  EPA  has assumed the lead for this site,  with the
State in an oversight role.

     In response to public comments  on an August 1989 proposed plan, EPA has
divided the site into two Operable Units (CUs).  OU#1 is  concerned with the
tailings and ground water contamination.  The ground water study  for this OU
is to be completed by September 1990 and a new proposed plan is to be
published by October 1990.

     QU#2 involves nearby contaminated residential soils.  EPA has completed
the RI/FS for this OU and expects to publish a proposed remedy shortly.

                                  Tooele,  Utah

     Conditions at listing (October 1984);  The Tooele Army Depot  (TEAD) is in
Tooele, Tooele County, Utah,  35 miles southwest of Salt lake City.  It
consists of two separate areas, the North Area and the South Area.  The North
Area covers about 25,000 acres in Tooele  Valley south and west of Tooele.

     Since 1943,  TEAD has  had a fourfold  mission: store ammunition,
demilitarize ammunition, rebuild  military equipment, and store military
equipment.  In fulfilling  its mission, TEAD decommissions munitions by cutting
the casings and removing and recycling the  explosive material.  The casings
are then rinsed with water to remove residual explosives.  Between 1948 and
1965, rinse waters were  discharged  into the "TNT Washout Area," which covers
less than 1 acre  in the  North Area.  The  Army has detected trinitrolotuene
 (TNT) and cyclomethylenetriamine  (RDX), an  experimental explosive, in soil
near the TNT Washout Area,  threatening ground water.  About 2,500 people
depend on wells within 3 miles of the site  as a source of drinking water.

     TEAD is participating in the Installation Restoration Program,
established in 1975.  Under this  program, the Department of Defense seeks to
identify, investigate, and clean  up contaminations from hazardous materials.
The Army has completed Phase I (records search).

     Status (May  1990);  Activities at Tooele are divided into two operable
units (CUs).  OU#1 involves ground  water  contaminated with organic solvents
and metals resulting from  an unlined industrial waste lagoon.  The Army has
closed the lagoon; the Utah Department of Health approved the closure on
November 1, 1989,  the deadline set  in a Consent Decree entered into earlier by
the Army, Utah, and the  U.S.  Department of  Justice.  A ground water assessment
required by the decree shows that a plume of ground water contaminated with
trichloroethylene (TCE)  and trichloroethane (TCA) has migrated downgradient
approximately 2 miles.   The leading edge  of the plume lies several hundred
yards beyond the  TEAD boundary and  may be migrating several hundred feet per
year.  TCE concentrations  vary from approximately 250 parts per billion  (ppb)
beneath the lagoon ditches to 8 ppb at the  TEAD boundary.  Of approximately 37
billion gallons of contaminated ground water, approximately 16 billion gallons
will require cleanup.  The proposed cleanup calls for installing an extraction
wellfield near the northern boundary of TEAD to intercept the leading edge of
the contaminant plume.   Ground water pumped from the wellfield will be piped
to a water treatment plant where  the contaminants will be removed by air
stripping techniques.  Treated effluent will be piped to an injection
wellfield upgradient of  the contaminant plume.

     OU#2 involves a landfill and facilities for ordnance demilitarization
that released TCE and TNT-related contaminants.  The Army is attempting to
define the extent of contamination  in OU#2.

     EPA, the State, and the Army plan to negotiate an Interagency Agreement
under CERCXA Section 120 covering future  activities at TEAD.

                              Portsmouth,  Virginia

     Conditions at listing (June 1988);  Abex Corp.  formerly operated a brass
and bronze foundry on a 2-acre site in a residential area of Portsmouth,
Virginia.  During 1928-78, Abex produced parts such  as brake shoes  and ball
bearings for railroad cars.  EPA estimates that lead was released to the air
at the rate of 10 pounds per day from  a 1-acre process area  and that 3,500
cubic yards of lead-laden furnace  sands were dumped  into an  adjoining 1-acre
area.  The present. owner of the former process area  is Holland Investment  &
Manufacturing Co. of Portsmouth; Abex  still owns most of the landfill area.

     In 1984, EPA identified elevated  lead levels in soil in the  fill area.
EPA sampling on April 2, 1986 revealed high levels,  up to 13,000  parts per
million  (ppm), of lead in residential  lots next to the fill  area.  Abex has
found significant soil contamination around both the landfill  and old process
areas.

     EPA collected wipe samples on home surfaces around the  site  on July 1-2,
1986.  The results indicated that  breathing-zone air contained lead,  copper,
and tin.  Over 10,000 people live  and  work within 1  mile of  the site.  A
number of residents live either on or  immediately adjacent to  the lead-
contaminated soils.

     EPA and Abex signed a CERCLA  Emergency Consent  Order on August 11, 1986.
Abex was required to reduce human  exposure to lead to levels that do not
constitute an imminent threat to health.  Abex graded the site; surrounded it
with cyclone fencing topped with barbed wire; covered much of  the old landfill
area with asphalt; and excavated some  areas adjacent to the  landfill, filled
them in, and revegetated to prevent exposure of residents to lead-
contaminated soil.

     The U.S. Centers for Disease  Control have determined that frequent
contact with 500-1,000 ppm of lead in  soil and dust  appears  to be associated
with elevated blood lead levels in children.

     Status (May 1990);  On October 10, 1989, EPA and Abex signed a Consent
Order under which Abex will conduct a  remedial investigation/feasibility study
(RI/FS) to determine the type and  extent of contamination at the  site and
identify alternatives for remedial action.  EPA is reviewing Abex's final
RI/FS workplan.

                            Silverdale, Washington

     Conditions at listing (July 1989);  The Bangor Naval Submarine Base
covers 7,000 acres on Wood. Canal near Silverdale, Kitsap County, Washington.
The area around the base is primarily residential.  Established in 1946, it
now has the primary mission of basing Trident submarines.

     In July 1987, a 6-acre hazardous waste site on the base known as Site A
was placed on the NPL under the name "Bangor Ordnance Disposal."

     The Bangor Naval Submarine Base is participating in the Installation
Restoration Program (IRP), established in 1978. Under this program, the
Department of Defense seeks to identify, investigate, and clean up
contamination from hazardous materials.  As part of IRP, the Navy has
identified 19 additional waste areas within 1.5 miles of each other where
industrial wastes and waste water containing explosives were mishandled.   The
areas include ordnance burn and disposal pits, pesticide storage and disposal
areas, a PCB spill area, a portion of Hood Canal with contaminated sediments,
and Clear Creek.

     Cyclonite  (RDX), trimtrotoluene  (TNT), ammonium picrate, ammonium
picramate, and propylene glycol dinitrate are present in numerous wells on the
base, according to IRP tests conducted in 1983.  An estimated 18,000 people,
including base employees and local residents, obtain drinking water from
public and private wells within 3 miles of hazardous substances on the  base.
Ground water is also used for irrigation.

     The 1983 tests identified most of the same explosives, as well as  copper
and lead, in surface waters and shellfish in three locations on the base.  The
waters drain into Hood Canal and Clear Creek.  Waste waters containing
explosives were routinely discharged to surface waters, and ships in Hood
rsmai were painted with paints containing heavy metals.  The Navy also  has
found these contaminants in shellfish in Hood Canal, which is used for
recreational activities and contains commercially  valuable fish and shellfish.

     Status (Mav 1990V;  On January 29, 1990, EPA, the Washington Department
of Ecology, and the Navy signed an Interagency Agreement under CERdA Section
120 covering remedial activities at the 20 identified hazardous waste areas at
the base, including Site A.  Combining similar hazardous waste  areas has
resulted in 10 operable units at the base.  Remedial investigations and
feasibility studies are scheduled to start in 1990 and  1991.

                              Gentralia,  Washington

     Conditions at listing (June 1988):   Centralia Municipal landfill is in
the southern  section of Centralia,  Lewis County, Washington.  It is bordered
on the east by railroad rights-of-way;  on the south by Salzer Creek, which
empties into  the Chehalis River; and on the north by a residential area.  The
site encompasses 80 acres, of which approximately 50 acres have been used as a
landfill  since the site opened in 1958.   The city received a permit from Lewis
County in 1974 to  accept municipal waste.

     An unknown quantity of hazardous waste containing PCBs and dioxin, as
well as other liquid industrial wastes,  has been deposited in the landfill,
according to  the Washington Department of Ecology (WDOE).  In 1986, EPA
observed  leachate  from the landfill entering floodwaters of Salzer Creek.  The
leachate  contained cadmium, chromium, iron, manganese,  and zinc at levels
exceeding Federal  primary and secondary drinking water standards,  according to
EPA tests.

     Ground water  at the site reaches the surface during the rainy season. The
upper  and lower aquifers are hydraulically connected so that water can move
between them.  Over 12,000 Centralia residents obtain drinking water from a
blended system that draws primarily from surface water but also uses the lower
aquifer within 3 miles of the site on a stand-by basis.  Surface water is used
for irrigation.

     WDOE is  working with the city to bring the landfill up to State and
Federal standards.

     Status (May 1990);  Ihe landfill is estimated to reach capacity in mid-
1991,  when it is scheduled to be closed.  Ihe city has prepared a closure plan
for the landfill,  which includes a surface water drainage control system,
landfill  gas  control system, leachate collection system, and a cap.

                              Spokane, Washington

     Conditions at listing  (June 1988);  The North Market Street Site is in an
industrial area 1.5 miles north of Spokane, Spokane  County, Washington.  The
site was originally proposed as "Tosco Corp.  (Spokane Terminal)."
Investigations subsequent to proposal indicate that  Tosoo nay not be the
primary source of problems at the site.

     In 1976, Tosco purchased a 50-acre portion of the  site,  which it now uses
as a bulk storage tank farm for petroleum products.  An oil refinery had
previously been on the property.

     According to information Tosco provided to EPA, as required by CERCLA
Section 103 (c), lead-containing wastes listed  as hazardous under Subtitle C of
the Resource Conservation and Recovery Act were disposed  of on the ground and
in holes, probably before 1970.  The site overlies the  Spokane Valley-Rathdrum
Prairie Aquifer, which EPA has  designated as a sole  source of drinking water
under the Safe Drinking Water Act.

     Soil in an old waste oil lagoon in the northwest corner  of the site
contains high levels of lead, according to Washington Department of Ecology
 (WDOE) tests conducted in 1986.   (A small part of the lagoon  is on Tosco
property.)  The soil overlying  the aquifer is  highly permeable, which
facilitates movement of contaminants into ground water.  Wells within 3 miles
of the site provide drinking water to over 200,000 people and are also used
for irrigating croplands.

     Status  (May 1990);  WDOE has detected organic chemicals  in ground water

     Conditions at  listing  (June 1988);   Seattle Municipal Landfill (Rent
Highlands)  is  in Kent,  King County, Washington,  approximately 14 miles south
of Seattle.  From June 1968 to December 1986, Seattle filled about 60 acres of
a 90-acre ravine on a hillside above the Green River. Seattle leased the site
from Kentview  Properties, Inc.,  and operated it  under a  "Nonconforming Permit"
from the Seattle-King County Department of Public  Health.

     In addition to municipal wastes from Kent and Seattle, the landfill
accepted sand-blasting grit, some industrial sludges, and other industrial
wastes, according to Health Department records.

     In 1984,  a consultant  to the county detected  zinc,  copper,  barium, and
manganese in on-site monitoring  wells.   Over 18,000 people obtain drinking
water from public wells within 3 miles of the site, the  nearest within 1 mile.

     Leachate  seeps on the  east  side of the landfill  mix with run-off from the
landfill, which is  routed through drainage lines to settling ponds that
eventually discharge to the Green River.  The river is used for spawning and
rearing salmon.

     In 1985,  a consultant  to Seattle detected 1,2-dichloroethane and
tetrachloroethylene in the  air at the edge of the  site.  An estimated 12,700
people  live within  1 mile of the site.

     Seattle is currently closing the landfill and developing plans to meet
all local, State, and Federal requirements.  Under a  Consent Agreement signed
with the State in May 1987, Seattle is conducting  a remedial investigation/
feasibility study  (RI/FS) to determine the type  and extent of contamination at
the site and identify alternatives for remedial  action.  The work is scheduled
to be completed in  April  1989.

     Status  (May 1990):  The original RI has been  completed.  Additional data
needs resulted in a Phase II RI, which is scheduled to be completed in June
1991.   The FS  is scheduled  to be completed in December 1991.  An interim
system  has been installed in an  effort to prevent  landfill gas from
concentrating  on-site or  migrating off-site.

                               DePere,  Wisconsin

     Conditions at listing fOctober 19891;  The Better Brite Plating Co.
Chrome and Zinc Shops occupy 2 acres and are approximately 2,000  feet from
each other in a primarily residential area of DePere, Brown County, Wisconsin.
Metal plating operations conducted at the shops since the early 1960s have
contaminated soil and ground water as a result of spills and leaking storage
facilities.  After the company filed for bankruptcy in October 1985,
operations ceased at the chrome shop.

     In April 1986, EPA used CERCLA emergency funds to remove  contaminated
soil, chromic acid, cyanide sludge, and flammable liquids from the chrome
shop.  All materials were transported to a hazardous waste facility regulated
under Subtitle C of the Resource Conservation and Recovery Act.   In May-June
1987, the Wisconsin Department of Natural Resources (WDNR) used the Wisconsin
Environmental Repair Fund to install seven monitoring wells, three of them
extending 20 feet into bedrock.  Soil and ground water were analyzed.  The
results indicated chromium contamination into both the shallow aquifer and  the
upper bedrock aquifer.  An estimated 46,000 people obtain drinking water from
municipal wells within 3 miles of the site.  DePere municipal  well #2 is about
500 feet downgradient of the zinc shop.

     During 1986-88, the State issued orders to stop operations at the zinc
shop.  Ihe site was abandoned in July 1989.

     In March 1988, WDNR received a complaint that yellow water was running
from the chrome shop into the city storm sewer.  WDNR found chromium in the
run-off and in soil at a neighboring residence.  The City of DePere is
periodically pumping a trench on the chrome shop property and  discharging the
waters to the DePere Wastewater Treatment Plant.  In October 1988, WDNR was
notified that the plating building at the shop had been sold and  was to be
removed.  To prevent exposure of grossly contaminated soil under  the building,
WDNR razed the building, partially fenced the site, installed  a clay cap,
covered it with top soil, and seeded the cover.

     In June 1988, EPA emergency funds were used to design a pretreatment
system for water being discharged from the site to the DePere  Wastewater
Treatment Plant.

     Status (May 1990):  EPA's pretreatment system for water being discharged
from the site to the DePere Wastewater Treatment Plant is scheduled to start
operating in June 1990.  A proposed operation and maintenance  agreement
between WDNR and the City of DePere is being presented to the  City Council  for
approval.

     A State court judge has ordered the Bankruptcy Trustee and the operator
to remove waste material from the-site,, as, per, NR 181-Wisconsin Administrative
Code.  The removal has not yet occurred.  Negotiations with the Bankruptcy
Trustee for obtaining removal are continuing.

                              Brookfield,  Wisconsin

     Conditions  at listing (June 1988);   Waste Management of Wisconsin, Inc.,
operated a  20-acre sanitary landfill in Brookfield, Waukesha County,
Wisconsin,  during 1969-81.   The company leased the site before purchasing it
in 1982.  Previously it had been a sand and gravel pit.  In 1976, Waste
Management  received a permit from the Wisconsin Department of Natural
Resources to accept municipal waste.

     Ground water on and off the site is contaminated with cyanide, according
to EPA tests conducted in 1985.  An estimated 11,000 people obtain drinking
water from  public and private wells within 3 miles of the site, the nearest
within 1,000 feet.

     Poplar Creek, 3,600 feet southwest of the site, is used for recreational
activities. A wetland is 1,800 to the southeast.

     In 1985,  Waste Management upgraded the landfill's system for extracting
and burning soil gas,  and in 1986 installed a clay cap.

     The site  is not completely fenced,  making it possible for people and
animals to  come  into direct contact with hazardous substances.

     Status (May 1990);   Waste Management is again upgrading the soil gas
extraction  and combustion system.  As part of the work, the clay cover is
being repaired where needed.

                              Evansville, Wyoming

     Conditions at listing (June 1988);  The Brookhurst residential
subdivision and an industrial area border on Mystery Bridge Road and U.S.
Highway 20 in Evansville, Natrona County, Wyoming.  To date, several sources
of <3ontamination have been identified at the site, which covers approximately
200 acres.  The search continues for other sources.

     One source is KN Energy, Inc., which has operated a natural gas
processing and transmission facility since 1963 on about 25 acres south  of the
subdivision at 5500 Yellowstone Highway  (U.S. Highway 20/26) east of Casper.
Until 1985, wastes drained into an unlined pit on the northeast corner of the
facility.   This unlined pit, which was replaced in December 1984 by a
concrete-lined structure, contains numerous hazardous substances, including
xylenes, ethylbenzene,  toluene, naphthalene, chrysene, methylnaphthalene, and
benzene, according to EPA tests conducted in 1987.  These substances were
detected in the shallow alluvial aquifer immediately north of the pit,
including private wells in the subdivision.  Within 3 miles of the site, this
aquifer has been the sole source of drinking water for about 400 people, an
alternate source for about 2,500 people, and a source to irrigate cropland.

     EPA's 1987 tests indicate that Elkhorn Creek, which passes through  the
middle of the KN Energy facility, is contaminated with toluene and
fluoroanthene.  Within 3 miles downstream of KN Energy the North Platte  River
is used for irrigation and recreational activities.

     The Dowell Schlumberger oil field service facility is also south of the
subdivision.  The facility occupies 10 acres on the east side of KN Energy at
5750 Yellowstone Highway.  EPA determined that this facility was the source of
chlorinated organic solvents, including trichloroethylene, tetrachloroethy-
lene, 1,1,1-trichloroethane, and 1,2-dichloroethylene, in private wells  in the
Brookhurst subdivision as far as 0.5 mile away, and also in Elkhorn Creek.

  .   EPA detected pentachlorophenol in monitoring wells along the Burlington
Northern railroad and U.S. Highway 20 rights-of-way and at several locations
in the subdivision.  The source or sources of this contamination is unknown.

     The State provided bottled water to about 400 subdivision residents for
1 month in late 1986.  Using CERCIA emergency funds, EPA supplied water  until
December 1987, when EPA provided the homes a permanent water supply.

     KN Energy, Dowell Schlumberger, and its parent company, Dow Chemical Co.,
signed a Consent Agreement with EPA on December 15, 1987 in which they agreed
to conduct a remedial investigation/feasibility study (RI/FS) to determine the
type and extent of contamination at the site and identify alternatives for
remedial action.  On the same day, KN Energy and Dowell Schlumberger/Dow
Chemical signed separate Consent Agreements to conduct removal actions on
their properties.

     Status  (May 1990);  KN Energy is extracting vapors from soil and pumping
and treating ground water.  The other two companies have removed some
contaminated soil and are operating two soil vapor extraction systems.   The
RI/FS is nearing completion.

                               Magnolia,  Arkansas

     Conditions at listing  (October 1989);  Magnolia  City Landfill comprises
two 40-acre tracts (one of which has not yet been vised)  located 2.3 miles
south of Magnolia, Arkansas, in Colombia County.  The area around the site is
forested, with some residences.

     The city has owned and  operated the site since 1955,  accepting
residential and commercial trash, as well as industrial  wastes,  from the area.
During 1955-65 and 1970-79,  56,100 gallons  of solvents and other organic
chemicals from Firestone Coastal Fabrics Co. in Magnolia were burned and the
residue buried at the landfill, according to information the company supplied
to EPA as required by CERCLA Section 103 (c); an additional 40,000 gallons were
also buried.  Since 1971, Alumax Magnolia Division  (formerly known as Howmet
Aluminum Corp. of Magnolia)  has deposited about 31,200 cubic yards of aluminum
hydroxide sludge containing  small amounts of phenolic glue and nickel,
according to information the company provided to  EPA. An EPA inspection in
September 1986 revealed that a large quantity of  sludge  was being spread
evenly on a portion of  the landfill.

     In 1987-88, EPA found benzene, trans-l,2-dichloroethylene,  and
trichloroethylene in on-site monitoring  wells.  An  estimated 200 people obtain
drinking water from private  wells within 3  miles  of the  landfill.

     EPA tests conducted in  February 1988 identified  lead and nickel in on-
site soil.

     Status (May 1990);  In  response to  public  comments, EPA re-evaluated the
site documentation and  the site's score  on  the  Hazard Ranking System used to
assess sites for the NPL.  Because the score is now below the cutoff point EPA
has established to include a site on the NPL, this  site  is being dropped from
consideration for the NPL at this time.

                              Concord, California

                 t listing (June 1988);  Concord Naval Weapons Station is
approximately 30 miles northeast of San Francisco on the southern  shore of
Suisun Bay,  in Concord,  Contra  Costa County, California.  The station is the
major ammunition transshipment  port on the West Coast for the Department of
the Navy.  In the  tidal area of the station are three disposal areas within
0.5 mile of  one another: the Tidal  Area landfill/ the R-Area Disposal Area,
and the Wood Hogger Area.   The  three encompass  over 110  acres in the western
portion of the tidal area.

     From the mid-1940s until 1979, the Tidal Area landfill was the primary
disposal site for  the  station,  receiving wastes from virtually all station
activities.  Hazardous wastes deposited at this location may include lead-
based paints, creosote-treated  timbers, asbestos, acids, waste solvents, and
waste oils.  The landfill  lies  in a diked salt marsh along Suisun  Bay, and
portions of  the materials  disposed  of there may periodically be underwater
during extremely high  tides or  rainfall.  The R-Area Disposal Area may contain
lead-based paints  and  waste solvents.  At the Wood Hogger Area, wood chips
contaminated with  pentachlorophenol were disposed of in  wetlands adjacent  to
and on top of the  tidal area landfill.  The total volume of hazardous wastes
deposited in the entire western portion of the tidal area is undetermined.

     Wells within  3 miles  of the site are used  for industrial purposes and
serve as backup for a  public water  system serving an estimated 185,000 people.
Surface water is not used  for drinking water or irrigation within  1 mile
downstream from where  contaminants  enter Suisun Bay.  However, the bay and its
marshes are  used extensively for recreational fishing and hunting.  The salt
marsh harvest mouse, designated an  endangered species by the U.S.  Fish and
Wildlife Service,  resides  in the tidal area.

     The station is participating in the Installation Restoration  Program
(IRP), established in  1978.   Under  this program, the Department of Defense
seeks to identify, investigate, and clean up contamination from hazardous
materials.   The Navy has completed  IRP Phase I  (initial  assessment study).
Phase II (confirmation/quantification study) is underway.

     Status  (May 1990);  In response to public comments, EPA re-evaluated  the
site documentation and the site's score on the Hazard Ranking System used  to
assess sites for the NPL.   Because  the score is now below the cutoff point EPA
has established to include a site on the NPL, this site  is being dropped from

                              Stockton, California

      Conditions at listing fJune 198811   Kearney-KPF, formerly known as KPF
 Electric Co.,  began operations in 1951 on a 11-acre site at 1624 East Alpine
 Avenue in Stockton,  San Joaquin County,  California.  The area consists
 primarily of small businesses and vacant lots.  During 1951-65, the only major
 waste generated was by a  silver-plating process.  In 1972, the company added a
 galvanizing operation.  Liquid wastes from the silver-plating and galvanizing
 operations  were disposed  of in two on-site unlined ponds until the summer of
 1985.   From then until  January 1986,  only rinse water was placed in the ponds.

     The liquid waste contained copper,  iron,  lead, mercury, silver, zinc,
 volatile organic chemicals,  cyanide,  and highly acidic and alkaline rinse
 water,  according to tests conducted in 1986 by a consultant to Kearney-KPF.
 The consultant also, found that on-site soils and monitoring wells contain 1,1-
 dichloroethylene,  tetrachloroethylene,  1,1,1-trichloroethane, and lead.  Water
 from seven  California Water Services  wells within 3 miles of the site is
 blended into a system that  serves an  estimated 128,000 people in the Stockton
 area.

     In February 1988,  the  company submitted a closure and postclosure for the
 facility.

     This facility is being proposed  for the NFL because it is classified as a
 non- or late filer under the Resource Conservation and Recovery Act (RCRA).
 Although the facility was treating, storing, or disposing of hazardous waste
 after November 19, 1980, it did not file a Part A permit application by that
 date as required and has little or no history of compliance with RCRA
 Subtitle C.

     Status (Mav 19901;  This RCRA site  is being dropped from the NPL because
 it is a late filer that has come within  the RCRA system and over the past 2
years demonstrated a history of compliance with RCRA regulations.

     Kearney submitted  a new draft closure plan in  May 1989 and is scheduled
to submit a draft RCRA postclosure permit in August 1990.   All closure/
postclosure options with corrective action include  RCRA financial assurance
and ground water monitoring requirements.

     Conditions at listing  (June 1988) ;  Solvent Service, Inc. ,  recycles waste
solvents frcm nearby industries on a 3.5-acre site at 1021 Berryessa Road in
San Jose, Santa Clara County, California.  The neighborhood is both
residential and industrial.  The site is paved and fenced.

     Waste solvents and reclaimed solvents are stored in drums and tanks on
the site.  Soil near the tanks contains high concentrations of volatile
organic chemical s , including trichloroethylene, trichloroethane, and
chloroform, according to tests conducted in 1983 by a consultant to the
company.  The same solvents were also found in monitoring wells on and off the
site.  Solvent Service is within 1 mile of a cluster of wells that are part of
the municipal supply for the area.  This supply serves a residential and daily
business population of about 132,000 people.

     In 1983, the company started to work under a voluntary cleanup agreement
with the California Regional Water Quality Control Board  (CRWQCB) .  In 1985,
CRWQCB issued Waste Discharge Requirements calling for the company to define
the extent of the contamination and to install wells to stop of f -site
migration.  The company's consultant has produced numerous reports that
attempt to map out the underlying hydrogeology.  The company has installed 95
monitoring wells, on- and off -site, and also installed extraction wells and
extraction trenches to stop contaminated ground water from migrating
off-site.

     This facility has a final permit to treat, store, or dispose of
Subtitle C hazardous waste  under the Resource Conservation and Recovery Act
(RCRA) .  The permit was issued before enactment of the Hazardous and Solid
Waste Amendments of 1984 and thus does not require corrective action measures.
The facility has not voluntarily modified the permit.  Hence, EPA believes
that use of CERCLA authorities will result in the most expeditious cleanup and
is proposing the site for the NPL.

     Status (May 1990) ;  This RCRA site is being dropped from the NPL because
on November 28, 1989 a RCRA permit with corrective action was issued.

     In early 1990, Solvent Service started to operate a pilot system to treat
contaminated soil.  The ground water system continues in operation.

     Solvent Service has prepared a remedial investigation/feasibility study
(RI/FS) to determine the type and extent of contamination at the site and
identify alternatives for remedial action.  CRWQCB received the RI/FS report
in January 1990.  The State plans to hear public comments on the proposed
remedial action plan in June 1990.

                                Richmond,  California

        Conditions at listing (October 1989);  The United Heckathorn Co. Site  is
   adjacent to the Lauritzen Canal at 402 Wright Avenue in Richmond, Contra  Costa
   County,  California.  The canal is on the Richmond Inner Harbor, which is  on
   San Francisco Bay, in an area that is primarily light industrial with some
   residential development.  The site includes the property where United
   Heckathorn Co. once operated and all other areas  where releases from that
   property have come to be located.

        From 1948 through 1965, several companies leased a 13.5-acre property  to
   process chemicals.  The owners have been: from 1947 through 1961, Parr
   Industrial Corp.; from 1961 through 1981, Parr Richmond Terminal Corp.; and
   from 1981 through the present, Levin-Richmond Terminal Corp.  (LRTC).  In  the
   late 1940s and early 1950s, Universal Pigment and Chemical  Co. produced napalm
   on-site.  From 1958 to 1965, Montrose Chemical Corp. contracted with United
   Heckathorn, United Chemetrics, and ChemWest  for DDT-grinding services.  These
   companies were tenants on the site during this period.  United Heckathorn Co.
   was the last company to formulate pesticides at this site  (1957-1965).  The
   current operation on the site involves metal recycling.

        The California Department of Fish and Game has recorded several instances
   of chemicals being discharged into the Lauritzen  Canal, including naphthenic
   acid in 1951 and DDT in 1960; The 1960 incident resulted in the death of  48
   striped bass.

        In August 1980, the California Department of Health Services  (CDHS),
   under its Abandoned Site Project, inspected  the site and found elevated levels
   of DDT, lindane, BHC, aldrin, and other pesticides in nine  soil  samples.

        In early 1983, LRTC hired a consultant  to study on-site DDT
   contamination.  Soils were found to contain  DDT and xylene, and  sediments from
   the canal contained DDT.  During the study,  parts of the site were  covered
   with 6 to 8 inches of crushed rock.  URTC's  Site  Characterization Plan  was not
   approved by CDHS, however, so CDHS is conducting  its own investigation  of soil
   and ground water contamination.

        The Richmond Inner Harbor is used  for recreational and commercial  fishing
   and shellfish harvesting, as well as recreational activities. A coastal
   wetland is less than 0.5 mile from the  site.  The harbor is part of San
   Francisco Bay, which the Water Quality Act of 1987 declared to be an estuary
   of national significance.

        In July-August 1988, EPA detected  DDT in the atmosphere at  numerous
   locations on and off the site.  An estimated 10,900 people  live within  1  mile
   of the site.

      Conditions at listing (June 1988);  Warner Electric Brake & Clutch Co.
 has manufactured drive  train components on a 93.9-acre site in Roscoe,
 Winnebago County,  Illinois,  since 1957.  Chlorinated solvents used in plant
 operations  are present  in two on-site lagoons that were covered by the  plant's.
 National  Pollutant Discharge Elimination System permit.   Tests conducted in
 1984 by Warner and its  contractor found that monitoring wells around the
 lagoons are contaminated with trichloroethylene (TCE),  1,1,1-trichloroethane,
 and trans-l,2-dichloroethylene.

      In 1983,  Winnebago County Public Health Department and the State found up
 to 5,700  parts per billion of TCE in private wells in  Hononegah Country
 Estates and Moore Haven Subdivision.   In 1984, the company constructed  a
 public water supply system for Hononegah Country Estates.  The system
 currently supplies 208  customers.   An estimated 7,400  people obtain drinking
 water  from  public and private wells within 3 miles of  the site.

      The  company also removed 16,000 tons of contaminated materials from the
 two lagoons, transported them to a hazardous waste facility regulated under	
 Subtitle  C  of  the Resource Conservation and  Recovery Act (RCRA), filled the
 lagoons,  capped the east lagoon with 1 foot  of compacted clay, and covered
 each with 6 inches of top soil.  The company continues to monitor  ground   , ;.._
 water.

      This facility is being proposed for the NPL because it is classified as a

      Status (May 1990);  Further review has  indicated  the site is  a converter,
 rather than a  non- or late filer,  under RCRA.  It is being dropped from the
 NPL as a  converter because on December 28, 1989, Warner Electric signed a
 Consent Order  under RCRA Section 3008(h)  for corrective action. The action
 requires:  (1)  reducing  contaminants in ground water  to the levels  set forth in
 the Consent Order through either removal of  contaminants or in-place treatment
 and (2) installing an alternate water supply for the individuals listed in the
 Consent Order.

     Conditions at listing  (January 1987);  Ford Motor Oo. produced B—24
bombers for the Federal Government  during World War U in Ypsilanti Township,
Washtenaw County, Michigan.  Sludge from the plating operation was piped to a
3-acre unlined lagoon on plant property.  The present owners are Ford Motor
and the Wayne County Road Commission, which operates the Willow Run Airport.
The abandoned lagoon is on airport  property.  Operations ceased in 1962.

     Ford Motor disposed of approximately 1 million cubic feet of sludge in
the lagoon, according to information the company provided to EPA as required
by CERCLA Section 103 (c).  Analysis of the sludge in 1979 by the Michigan
Department of Natural Resources detected PCBs and heavy  metals, including
lead, cadmium, and mercury.

     A noncontinous sand and gravel aquifer underlies the area at a depth  of
65 to 100 feet.  An estimated 60,000 people draw drinking water from municipal
wells within 3 miles of the site.   Private wells are also in the area, the
nearest about 2,000J feet from the site.

     The nearest downslope surface  water, Willow Creek,  is 800 feet from the
site.  It is potentially threatened because the lagoon is unlined and had  no
structures to divert run-off.  Belleville lake, 3,600 feet from the site,  is
used for recreational activities.

     The site is unfenced, making it possible for people and animals to  come
in direct contact with hazardous substances.

     Status (May 1990):  Subsequent to proposal of  this  site,  EPA learned  that
a number of industries discharged sludges to the lagoon, as did a waste  water
treatment plant north of the lagoon.  Therefore, the site would more
appropriately be named "Willow Run  Sludge Lagoon".   However, in response to
public comments, EPA re-evaluated the site documentation and the site's  score

     The site contains storage and process  tanks, two sand filter beds,  a
lagoon, numerous rusting drums, and  piles of sludge.  At least 2,000  cubic
yards of liquids and  sludges containing  phenol, naphthalene, chloroform,
anthracene,  and  lead  were  deposited  in the  lagoon and in sludge  piles,
according to tests conducted by the  Mississippi State Chemical Laboratory.  A
State inspection in 1984 determined  that the filter beds overflow onto
adjoining property, and that the  lagoon  discharges  to the  West Pascagoula
River.  A coastal wetland  is within  1,200 feet.

     The aquifer below the site consists of the sand and gravel  units of the
Citronelle Formation.  The formation is  the shallowest aquifer in the area of
the site and is  used  by a  small portion  of  the population.  About 300 people
are served by private wells in the aquifer  within 3 miles  of the site.  The
nearest well is  less  than  2,000 feet away.

     On April 24, 1985, EPA issued an  Administrative Order on  Consent to

and zinc, according to analyses conducted by EPA in  May 1986.

     In October 1984 and May 1986, EPA found barium, iron, lead,  and manganese
in the abandoned on-site drinking water well.  Soils in the area are permeable
and ground water shallow (26 feet in some cases),  conditions that facilitate
movement of contaminants into ground water.  Approximately 3,000 people,
including Allen residents, obtain drinking water from  public and private wells
within 3 miles of the site.

     Little Sandy Creek  and a tributary to the Canadian River originate on the
site.

     Status (May 1990):  In response to public comments, EPA re-evaluated the
site documentation and the site's score on the Hazard  Ranking System used to
assess sites for the NPL.  Because the score is  now  below the cutoff point EPA
has established to include a site on the NPL,  this site is being dropped from,.
consideration for the NPL at this time.

                                Sour lake, Texas

     Conditions  at  listing (June 1988);   The Rio Grande Oil Co.  Refinery
covers approximately 11 acres west  of Ann Street in Sour Lake,  in southwestern
Hardin County, Texas.  Now abandoned,  the refinery operated during the 1920s
and 1930s.   Liquid  wastes generated by petroleum and related refining
activities were  deposited in an unlined  disposal pit encompassing
approximately 1  acre.  The pit now  contains a hardened tar-like substance.
Parts of the site are now owned by  Arco, Amoco Production U.S.A., the City of
Sour Lake, and an individual.

     In 1986, EPA found phthalate esters and polycyclic aromatic hydrocarbons
in soil, some at depths of 3-5 feet.  The uppermost aquifer, the Chicot
Aquifer in the lower Beaumont Clay  Formation, is exposed in Sour Lake.  Area
soils are moderately permeable and  ground water occurs at 10-20 feet.  These
conditions potentially threaten ground water.  Sour Lake has two municipal
wells 1,000  yards southeast of the  site.  An estimated 2,000 people obtain
drinking water from public and private wells within 3 miles of the site.

    This site is on the Texas State list of sites targeted for cleanup under
Superfund.

     Status  (May 1990);   In response to  public comments, EPA re-evaluated the

                     PORT HOWARD PAPER CO.  SLUDGE LAGOONS
                             Green Bay, Wisconsin

     Conditions at listing (June 19881;  Fort Howard Paper Go.  owns and
operates a 293-acre disposal site within the corporate limits of the City  of
Green Bay, Brown County, Wisconsin.  The site is adjacent to the Oneida Indian
Reservation, Town of Hobart, and Village of Ashwaubenon;  Austin Straubel
Airport is about 600 feet to the south.  The company's manufacturing plant is
on Broadway Street about 3.5 miles from the disposal site.

     Disposal of sludge began in 1964 in a series of lagoons separated by
dikes constructed of on-site sands.  The sludge contains  barium, lead,
arsenic, and PCBs, according to tests conducted by a Fort Howard Paper
contractor in 1980. To date, sludge has been placed in Ponds 1-6,  9,  10, 11,
and 14, which are unlined; surficial soils beneath are silty sand.   An
abandoned landfill operated by the Village of Ashwaubenon is east  of Pond  10
and north of Pond 11.  The landfill was closed in the mid-1970s and is now
owned by Fort Howard Paper.

     Several monitoring wells on and around the site are  contaminated with
benzene and chlorinated organic solvents, according to a  1986 report of the
Wisconsin Department of Natural Resources.  The cxantamination cannot be
conclusively attributed to the sludge disposal practices. However,  the
permeable soils and shallow ground water (5 feet in some  cases)  increase the
potential for contaminants to move from the sludge lagoons into ground water.

     The Village of Ashwaubenon has two drinking water distribution systems.
Wells for both systems are within 3 miles of the site.  The City of Green  Bay
obtains its water from Lake Michigan via pipeline but maintains a  number of
wells as backup, one within 3 miles.  Drinking water for  an estimated 34,200
people is potentially threatened.

     Fort Howard installed a slurry wall/gradient control system in 1986 to
prevent migration of contaminants via ground water and fenced the  entire
property.

     Status (May 1990):  In response to public comments,  EPA re-evaluated  the
site documentation and the site's score on the Hazard Ranking System used  to
assess sites for the NFL.  Because the score is now below the cutoff point EPA
has established to include a site on the NPL, this site is being dropped from
consideration for the NPL at this time.
