NATIONAL PRIORITIES LIST AS OF FEBRDARY 1990
                                                                       svX3i 's

       This document consists of descriptions of the 137 sites (xncdudijnig^24
   Federal facility sites) proposed for the National Priorities List (NFL) as of
   February 1990.  In some (but not all) cases, there is a status section
   describing activities subsequent to proposal.  In general, summaries have not
   been updated since they were last issued but have merely been compiled here
   into one document as a convenience.

       The size of the site is generally indicated, based on information
   available at the time the site was scored using the Hazard Banking 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
                                                 SuperfuDd
       Ihe Superfund program is authorized by the Comprehensive Environmental
   Response, Compensation, and Liability Act (CERdA) , enacted on December 11,
   1980, and the Superfund Amendments and Reauthorizaticn 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.  Ihe
   Superfund program is managed by the U.S. Environmental Protection Agency
   (EPA).

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

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

       o Remedial responses, actions intended to provide permanent solutions at
         uncontrolled hazardous waste sites.  Remedial responses are generally
         longer-term and more expensive than removals.  A Superfund remedial
         response can be taken only if a site is on the NFL.   After publishing
         two preliminary lists and proposing a formal list,  EPA published the
         first NFL in  September 1983.  The list must be updated at least
         annually.
       Ihe money for conducting a remedial response or removal action at a
   hazardous waste site can come from several sources:
       o Ihe 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 under Superfund is an orderly process that generally
involves the following steps:

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

    o Undertake initial planning activities  to scope out a
      strategy for collecting information and analyzing
      alternative courses of action.

    o Conduct a remedial investigation to determine the type
      and extent of contamination at the site.

    o Conduct a feasibility study to analyze various cleanup
      alternatives.  The feasibility study is often conducted
      with the remedial investigation as one project.  Typically,
      the two together cost $1 million and take from 9 to 18
      months to complete.

    o Select the cleanup alternative that:

        — Protects human health and the environment

        — Attains Federal and State requirements  that are
           applicable or relevant and appropriate

        — Makes maximum use of  permanent solutions, alternative
           treatment technologies, or resource recovery
           technologies

        — Is "cost effective" — that is, the results achieved
           are proportional to the cost (tentative working
           definition)

    o Design the remedy.  Typically, the design phase costs
      $750,000 and takes 6 to 12 months.

    o Implement the remedy, which might involve, for example,
      constructing facilities to treat ground water or removing
      contaminants to a safe disposal area away from the site.
      The implementation phase typically lasts 6 to 12 months.
                                                                                   ^[^^^^^

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

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

    o EPA can take the lead under a Superfund State Contract,
      with the State having an advisory role.  EPA,  generally
      using contractor support, manages work early in  the
      planning process.  In the later design and implementation
      (construction)  phases, contractors do the work under the
      supervision of the U.S. Army Corps of Engineers. Under
      both arrangements, the State must share in the cost of the
      implementation phase of cleanup.  EPA expects this  phase
      to average out at about $13.5 million per site,  plus any
      costs to operate and maintain the remedial action.

                                 ARCTIC SURPLUS
                                Fairbanks,  Alaska

     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.  On-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 is warranted.  A drum inventory showed approximately 1,700
drums contained liquids  or sludges,  some flammable or corrosive.  Chlordane, a
very toxic pesticide,  was detected in soils at a concentration as high as
320,000 parts per million.

     EPA started a  removal action  in September 1989 to stabilize the site and
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.

                           ELMENDORF AIR FORCE BASE
                    Greater Anchorage Area Borough, Alaska

    Elmendorf Air Force Base covers 13,100 acres in the Greater Anchorage Area
Borough inmediately 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).
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 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 feed 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-dichloroethane,
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 wells within  3 miles of hazardous substances  on the base.

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

                             FCKT WAINWRIGfT
                   Fairbanks North Star Borough, Alaska

    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 which 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 Wainwrignt is participating in the Installation Restoration  Program
(IRP).  Uhder this program, established in 1978, 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 chrcmium 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.

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

    Hie Army is developing a workplan for a remedial investigation/feasibility
study 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.

                            Anchorage, Alaska

    The Standard Steel & Metal Salvage Yard covers  6.2  acres in a heavily
industrial!zed 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-<:antaminated 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, EFA 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 wells within 3 miles of the site.

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

    using CERCLA emergency funds, EFA has  conducted removal actions at the site
during the summer seasons starting in 1986.  EFA removed surface wastes —
including an estimated 8,500 batteries,  175 transformers, 1,100 drums,  3 bulk      I
storage tanks, assorted containers, and  metal debris—and transported the materials
to EFA-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.

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

             T. H.  AGRICULTURE &  NUTRITION CO. (MONTGOMERY PLANT)
                              Montgomery, Alabama

     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.

                               Magnolia,  Arkansas

      Magnolia City Landfill comprises two 40-acre  tracts  (one of which has not
 yet been used) 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.

                              Paragould, Arkansas

      The Monroe Auto Equipment Co. Pit covers 4 acres  including a 1-acre
disposal area on Finch Road in Paragould, Greene County, Arkansas.  Ihe area
around the site is rural.

      In 1973, the company received temporary approval  from the Arkansas
Department of Pollution Control to dispose of electroplating sludges into a
pit that had formerly been mined for sand and gravel.  The conpany says that
during 1973-78 it 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  used as degreasers during the
electroplating process.

      Qn-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-dLichloroethylene, 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.

                             APACHE POWDER  CO.
                             St. David, Arizona

     Conditions at listing  (June  1986):  Apache  Powder Co.  has manufactured
explosives and fertilizers  since  1922 near St. David, Cochise County,  Arizona.
Large quantities of nitrates have been used.  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 ranaina from 6
to 8 feet deep.  About 15 ponds coverina 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-nitroaen in waste  water.  Soil in
the bottom of the dry ponds also  contained hiah  levels of nitrate-nitroaen, as
did ash in a burning ground located in a dry wash.

     In 1980, EPA detected  toxic  heavy metals in one laaoon at levels  above
drinking water standards.   In 10  shallow wells believed  to be downaradient of
Apache Powder, ADHS and the Southeastern Arizona Governments  Oraanization
detected nitrate-nitrogen in excess of drinking  water standards.   At one time,
8 of the 10 wells were used for drinkinq water.  Because nitrate is verv mobile,
it is likely that it migrates faster than  toxic  heavy metals, which will likely
follow the same path.

     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);  This facility is beina proposed for the NPL  because
it is classified as a non-  or late filer under the Resource Conservation and
Recovery Act (RCRA).  Although the facility was  treatina, storina,  or  disposina
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.

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

                             LUKE AIR FORCE BASE
                              Glendale, Arizona

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

     Luke Air Force Base 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.  Under IRP, the Air Force has  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, trichloro-
 ethylene, 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 corner 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 2-dichloro-
 ethane 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

    The Air Force has completed an initial assessment of the base, and  its

 determine the type and extent of contamination and  identify alternatives for
 remedial action.

                               Concord, California

     The  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 contains 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, the
specially funded program established in 1978 under which the Department of
Defense has been identifying and evaluating its past hazardous waste sites and
controlling the migration of hazardous contaminants from these sites.  The Navy
has completed Phase I (initial assessment).  Phase II  (confirmation study) is
underway.

                          CRAZY HORSE  SANITARY  LANDFILL
                               Salinas, California

      The Crazy Horse Sanitary Landfill is  on Crazy Horse Canyon Road within the
 southeastern portion of the hilly  reqion in Salinas  in  northern Monterey Countv,
 California.  The 125-acre site is  owned by the City  of  Salinas and operated bv
 Salinas Disposal Services.  Prior  to  1950, the site  operated as an ooen burnina
 dump.  Since 1950,  it  has been a sanitary  landfill.   In 1977, it  received a
 permit from the California  Reqional Water  Quality  Control Board (CRWCCB) to
 accept residential, commercial, and industrial wastes.   Some pesticide containers
 have been disposed  of  at the facility after triole-rinsina as reauired hv
 California law.  The CRWQCB permit prohibits acceptina  hazardous  waste.
 According to Firestone Tire & Rubber  Co.,  its  olant  in  Salinas disposed of
 large cruantities 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, CRWQCB sampled three downaradient residential wells.
 They were found to  be  contaminated with volatile oraanic chemicals,  includina
 benzene and toluene.   An estimated 6,200 people obtain  drinkina water from
 private wells  within 3 miles of the site.

      A consultant to the City of Salinas conducted an extensive around 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 suqaested that there may be a
 secondary source on private property  adiacent  to the landfill.

      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.  Then six  permanent  extraction wells were
 installed downgradient of the landfill, and the residential wells were capped
 and sealed permanently.  Contaminated water is pumped from the extraction wells
 and is then treated by passive air strippinq.   The treated water  is discharaed
 to a sediment  retention basin on-site.  When the water  reaches the basin, the
 contaminants of concern cannot be  detected.

                              Kern County, California

    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 MDjave 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).
Under this program, established in 1978, 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.  Of
these, 6 are active, and 15 have been cleaned up and require no further action,
according to the Air Force.  Investigation has  focused on the Main/South Base
area, the North Base area, and the Air Force Astronautics Laboratory area.

    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.

    On the North Base area,  5 miles to the northeast of the Main Base area,  is
a drum storage area at the north end of Rogers  Dry Lake, and three unlined
surface impoundments into which wastes were poured during the 1960s and 1970s.
Contaminants include waste oils, solvents, and  nitric acid generated primarily
by the Air Force Rocket Propulsion Laboratory.

    Trichloroethylene, trans-1,2-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.  Qantaminants at the North Base area could migrate
downwards and reach ground water that serves the 1,300 residents of North
Edwards.

    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.

              FAIRCHILD SEMICONDUCTOR CORP.  (MOUOTAIN VIEW  PIANT)
                           Mountain View, California

     Conditions at listing (October 1984);   Fairchild Semiconductor  Corp.  manu-
factures semiconductors in Mountain View, Santa Clara County,  California.   The
facility occupies approximately  56 acres and is surrounded  by residential  and
industrial areas.

     This site was originally proposed under the  name "Fairchild Camera &
Instrument Corp. (Mountain View  Plant)."  The company took  the new name in 1986.

     Monitoring wells on the site are contaminated  with trichloroethylene,
1,1,1-trichloroethane,  1,1- and  trans-l,2-dichloroethylene, according to
analyses conducted by a consultant to Fairchild.  Contamination is believed
to have resulted from leaking underground tanks.  About 270,000 people depend
on wells within 3 miles of the site for drinking  water.

     Since early 1982, Fairchild has been  investigating the site geology and
hydrogeology and attempting to define the lateral and vertical extent of solvents
underlying the site.  Fairchild  has installed two wells to  pump and  treat  the
contaminated ground water plume.  The company is  working with the California
Regional Water Quality Control Board to further define  the  extent of contami-
nation and outline various cleanup strategies.

     The plant received  Interim  Status under Subtitle C of  the Resource
Conservation and ftecovery Act  (RCRA) When  the company filed Part A of a
permit application.

     This is one of  19  sites in  the South Bay Area  of San Francisco.
Facilities at these  sites have used a variety of  toxic  chemicals, -primarily
chlorinated organic  solvents, Which contaminate a common ground water basin.
Although these sites are listed  separately,  EPA  intends to  apply an  area-
wide approach to the problem as  well as take specific action as necessary.

     Status (February 1986);  Continuing efforts  to determine the extent of
ground water contamination, Fairchild has  installed more than 100 monitoring
wells. . The two treatment wells  are now  in operation.

     The California  Regional Water Quality Control  Board has issued  Waste
Discharge Requirements  to the company.  The  requirements are the board's
legal mechanism for  regulating  facilities  under  its jurisdiction.

     On August  15, 1985, EPA issued an Administrative Order on Consent under
CERCIA Section  106(a) to Fairchild's Mountain View Plant, as well as to Intel
Corp.'s and Raytheon Corp.'s Mountain View Plants.   The order calls for the
companies to conduct a  joint remedial  investigation/feasibility study of the
area to determine the type and extent of contamination  and  identify alternatives
for remedial action.

     Status (June 1988);  EPA  is proposing to drop Fairchild Semiconductor
Corp.'s Mountain View Plant  from the proposed M>L.   Because the site is a
treatment and storage  facility,  it  is  subject to the corrective action
authorities of Subtitle C RCRA.

     EPA has been overseeing the RI/FS  required under the August  1985 order.
A preliminary draft  FS  is scheduled  to be  available for public review in July
1988.

     Fairchild now has  25 wells in operation that pump and treat  contaminated
ground wtaer; has  installed  three underground slurry walls to control migration
of contaminated ground  water;  and has  sealed 4 old agricultural wells.

     EPA may also pursue cleanup under  RCRA authorities and will  ensure that the
cleanup protects public health and  the environment.  EPA can  later  repropose the
site for the NPL if  it  determines that the owner or operator  is  unable  or  unwilling
to clean up the site effectively.

                             Livermore, California

     Hexcel Corp. operates on  a  22-acre  site in Livermore,  Alameda County,
California.  The company formulates and  reacts  clastic resins for coatinos and
adhesives and custom-impregnates fabrics for production  of  reinforced parts
for the aerospace industry.  Two documented spills occurred at the site in
1983.   In the first, 600 qallons of AP-92 solvent, which consists of methvlene
chloride, methyl ethyl  ketone  (MEK),  acetone, and isopropvl alcohol, leaked
from subsurface plumbing.  In  the  second, 1,500 aallons  of  MFK were released
when a  valve on a storage tank was left  open.

     In March 1983,  after the  first spill, the  California Peaional Water
Quality Control Board  issued a Cleanup and Abatement  Order  under the California
Water Code charginq  Hexcel with  improper waste  manaaprnent.   Under the order,
Hexcel  was to investiaate the  extent  of  contamination, clean UP soil and around
water,  and prevent future spills.  Hexcel excavated the tank and drilled a well
to recover as much of  the solvent  as  possible.   Approximately 5nn aalions of
the second spill were  recovered, but  the rest miqrated 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.  Monitorina continues to
define  the extent of contamination.   An  estimated 50,000 people obtain drinkina
water and 2,800 acres  of agricultural land are  irriaated from wells within 3
miles of the site.

     This facility obtained  Interim Status under Subtitle C of Resource Conser-
vation  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 aenerator-only
status  with EPA or State approval. Hence, it satisfies a component of FPA's
NPL/RCRA policy.

                          INDUSTRIAL WASTE PROCESSING
                              Fresno, California

      Industrial Waste Processing (IWP)  occupies approximately  0.5 acre  at
 7140 North Harrison Street in Fresno, Fresno County, California.  The 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 CERCLA 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.

      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

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 and piping involving the two companies.  More  than 300,000 people obtain
^drinking  water  from public wells within 3 miles of the site.

      In June 1986,  the California Regional water Quality Control Board issued

      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.

      This facility is being proposed for the  NPL 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.

           LAWRENCE LIVERM3RE NATIONAL LABORATORY  (SITE 300)  (USDOE)
                            Livermore, California

    Lawrence Livermore National Laboratory (LLNL)  (Site 300)  covers
approximately 2.75 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 and 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 NPL 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 the 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 iiipoundments.
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, LLL 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.

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

      Solvent  Service, Inc., recycles waste solvents from  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 underground
 tanks on the  site.   Soil near the tanks contains high  concentrations  of volatile
 organic chemicals,  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  off-site migration.
 The company's consultant has produced nuinerous 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.

     Spectra-Physics,  Inc. (SP)  has manufactured electronic equipment and
gas  lasers  on Terra Bella Boulevard and Middlefield Roads in Mountain View,
Santa Clara County, California,  since 1961.  The 11.5-acre site consists of
nine buildings in  a light industrial complex.  SP uses a variety of cleansers,
degreasers, and lubricants in its  manufacturing processes, including isopropyl
alcohol,  acetone,  methyl alcohol,  trichloroethylene (TCE), Freon, 1,1,1-
trichloroethane (TCA), and solvasol Solvent 360.  In an inspection conducted
in 1981,  the  California Regional Water Quality Control Board found that areas
where hazardous wastes were stored had no dikes or systems to collect leachate;
rusty barrels were also found on-site.

     Ground water  investigations began at the SP facility in September 1984
after tests at Teledyne Semiconductor (adjacent and downgradient of SP)
indicated possible upgradient sources' of contamination.  (The Teledyne site
was  placed  on the  NPL  in July 1987.)   Soil and ground water collected at SP
contained TCE, TCA, and 1,2-dichloroethylene.  SP's plume of contaminated
ground  water  has merged with Teledyne's and migrated off-site.  More than
200  private drinking water wells had been drilled into the 1-square-mile plume.
Most wells  have been closed; 47 were found contaminated above state Action
Levels.   The  owners now obtain water from municipal water supplies.  An
estimated 189,000  people obtain drinking water from public and private
wells within  3 miles of the site.

     Teledyne is operating one shallow extraction well on-site.  The well
pumps the water to the surface and discharges it to the sanitary sewer;
the  ground  water is not treated before discharge.  SP will evaluate the
effectiveness of this  system in preventing its on-site plume from migrating
off-site.  Both companies are jointly designing an off-site extraction
system;  completion is  scheduled for 1988.

     San Francisco Bay (2.5. miles downstream of the site) is used for
recreational  activities.  Permanente Creek is tidally influenced within 1 mile
of the  site.   Several  species of birds designated as endangered species by the
U.S. Fish and wildlife Service are found within the area of tidal influence.

                           SULPHUR BANK MERCURY MINE
                             Clear Lake, California

      The Sulphur Bank  Mercury Mine (SBM) 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 approxi-
 mately 23 acres and is 750 feet upgradient of the lake.  The pit is filled
 with water to a depth  of 150 feet.  It drains at approximately 20 gallons per
 minute from the western edge of the pit to Clear Lake.

      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.   Under the act, BMC is required to submit a
 Hydrogeologic Assessment Report.   However, the property owners are conducting
 a  waste characterization study of the site prior to submitting a Hydrogeologic
 Assessment Report to determine if the site may be exempt from the Toxic Pits
 Cleanup Act.

      An estimated 4,700 people obtain drinking water from clearlake Oaks Water
 District wells about 1 mile from the site.  The wells are threatened because
 they are recharged by  Clear Lake.   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.

      This mining site  is being proposed for the NPL because the state of
 California does not have an approved program under the Surface Mining control
 and Reclamation Act of 1977 (SMCRA), making the site ineligible for SMCRA
 reclamation funds.

                              Tracy, California

    The Tracy Defense Depot covers 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 until 1963, when it was turned over to the Defense Logistics Agency.  In the
course of depot operations, supplies are stored and issued, and several  industrial
activities are carried out.  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 above-ground and below-ground
waste tanks.  Also, liquid wastes were formerly stored on-site in an unpaved
storage area, and hazardous materials (including solvents, radiological
comnodities, 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      t
items were buried, a fill area where construction material was buried, and three
inpcundments 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).  Under this program, established in 1978, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous materials.
According to IRP tests conducted in 1985,  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 to determine the type and extent of contamination at the depot
and identify alternatives for remedial action.  The work is scheduled to be
completed in mid-1990.  The State is reviewing the depot's proposal to undertake an
interim remedial measure involving pumping out contaminated ground water and
treating it to remove the contamination.

                             Richmond, California

      The United Heckathorn Co. Site occupies 13.5 acres 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.  The area is primarily light industrial with some residential
 development.

      From 1948 through 1965, several companies leased the site 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).  Current site
 operations involve 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,  which resulted in the death of 180 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.  LRTC'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 other 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.

     The Watkins-Johnson  Co.  (Stewart Division Plant)  has manufactured
industrial furnaces and electrical  parts since 1965 on a 3-acre site in
Scotts Valley, Santa  Cruz County, California.   The California Regional
Water Quality Control Board  (CRWQCB)  and Watkins-Johnson's consultant have
detected organic  chemicals,  including trichloroethene, trichloroethane,
tetrachloroethene, dichloroethene,  and Preon in soil and ground water on
the site.  The contamination is apparently the result of improper handling
of hazardous waste.

     Early in July 1986,  the CFWQCB issued Waste Discharge Requirements to
the company.  The reguirements are  the CRWOCB's legal mechanism for regulating
activities at facilities  under its  jurisdiction.  Later in July, CRWOCB
issued a Cleanup  and  Abatement Order to the  company.  In response, Watkins-Johnson
has begun an interim  program to pump and treat contaminated ground water.

     Wells within 3 miles of the site draw on the Santa Margarita Aguifer,
designated by EPA as  a "sole source"  of drinking water in the area.  An
estimated 12,000  people use  the wells.

                         WESTERN  PACIFIC RAILROAD CO.
                              Oroville,  California

      Western Pacific Railroad Co. 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  included
 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 also was 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 impoundment 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.  The work called for 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.

     Chemical Sales Co. is a family-owned chemical distribution business
located at 4661 Monaco Street in an industrial area of Commerce City, Adams
County, Colorado.   The company has operated on the 10-acre site since 1977.

     The chemicals handled include ketones, alcohols, aliphatic carpounds,
and chlorinated hydrocarbons such as tetrachloroethylene, 1,1,1-trichloroethane,
and methylene chloride.  Sane chemicals are purchased in bulk  and stored
in tanks fron 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,
tetrachloroethylene, trichloroethane,  methylene chloride, and  chloroform in  on-
site wells and downgradient off-site wells.  An estimated 33,000 people
obtain drinking water  from South Adams County Water and Sanitation District

                             Cheshire,  Connecticut

     The Cheshire Associates Property occupies 15 acres (including two
residences  with private wells)  in Cheshire, New Haven County, Connecticut.
According to the Connecticut Department of Environmental Protection (CT DEP),
Cheshire Associates, a New York-based partnership, has owned a major portion of
the site since  1966.   The  company leased its property 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 and 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.

     Soil and ground water on the site are contaminated with volatile organic
chemicals,  according to a  government  study in December 1980.  In June 1985, EPA
found organic contaminants in both on-site shallow wells and an off-site bedrock
well; two residential  wells 400  feet  south of the site are contaminated with
low concentrations of  1,1,1-trichloroethane, 1,1-dichloroethylene,  and tetra-
chloroethylene.  Approximately  330 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.

     The site is in a  low-lying  fresh water wetland area bordered by two ponds.

     In 1983, CT DEP signed a Consent Agreement with  Cheshire Associates
requiring the company  to remove  contaminated soil on-site and to monitor eight
volatile organic compounds in the 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-l,2-dichloroethylene,
benzene, xylenes, and  tetrachloroethylene in the private wells.

                            New London, Connecticut

      The New London Submarine Base covers 1,412 acres on the east bank of the
 Thames River, New London, New London County, (jonnecticut.  The area around the
 base is mixed industrial, ocranercial, 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 corpounds, 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  (DPDO)  area,
 which was used as a burning ground and landfill from 1950 to 1969.   The third
 area is the Over Bank Disposal Area (OBDA), 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.

                              Cheswold, Delaware

     Conditions at listing (January 1987):  Chem-Solv, Inc., started a small
solvent distillation facility in 1982 on a  1.5-acre site in Cheswold, Kent
County, Delaware.  The company recycled waste solvents by olacina 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.  The residues remainina 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 at the site destroyed the
entire distillation facilitv.  At the time, witnesses observed fluids flowina
off a concrete pad into the soil.  On September 21, 1984, and aaain on Januarv
31, 1985, the Delaware Department of Natural Resources and Environmental
Control (DDNREC) issued orders under State  law callina on the company to  cease
operations immediately, monitor ground water, and remove all contaminated
soil.  The company failed to take any action.

     DDNREC conducted studies to characterize the upper Columbia Aouifer
adjacent to the site.  DDNREC1s analyses detected hiah concentrations of
organic chemicals, including trichloroethylene, 1,1,1-trichloroethane, and
1,1-dichloroethane, in soils on the site and in around water on and off the site.
Both the upper and lower zones of the Columbia Aouifer 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 beaan usina  a
process that passes air throuqh the soil to remove volatile oraanic contaminants.
The air-strippinq 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 Aouifer usina
an air-stripping system.

     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 permit apolication
under RCRA, giving the company Interim Status as a storaae facilitv.  On
August 6, 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 NPL/RCRA policy.

     Status (June 1988):  In May 1987, a domestic well near the site was  found
to be contaminated by volatile organics and was removed from service.

     After this site was proposed in Januarv 1987, procedural issues arose  and
new technical information became available.  Hence, EPA is reoroposina this
site to allow an additional 60-day comment  period.

                       KENT COUNTY LANDFILL (HOUSTON)
                             Houston, Delaware

     The  Kent County (Houston) Landfill covers 70 acres on Route  397  in the
Brown's Branch Watershed, 2.1 miles north of Houston, Kent County,  Delaware.
The watershed is  a tributary to McCauley Pond, Murder Kill River  (Cripple  Swamp),
arid the Delaware  Bay.

     The  landfill, owned and 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
ard other vegetation.

     Organic and  inorganic contaminants, including 4-methyl-2-pentanone,
4-methylphenol, chromium, arsenic, and manganese, are present  in  a  monitoring
well,  according to tests EPA conducted in May 1986.  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.  Approximately  1,200 acres  of
cropland  within 3 miles of the site are irrigated by wells.

     During EPA's May 1986 inspection, leachate was observed seeping  from  the
landfill.  The leachate contains chemicals that may threaten 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.

                               Newport, Delaware

     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  (PAHS),
such as benzo(a)anthracene, pyrene, fluoranthene, chrysene, and
benzo(a)pyrene,  in on-site soil, as well as in nearby creek sediment samples.
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.

     Approximately one-third of the site is wetlands, and additional wetlands
border the site.

manufacturing plant under the names Sealand Limited 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 (DDNREC) 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 CERCLA 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 1,000 people.

     Joy Run, which receives drainage from the  site, flows into the Chesapeake
arid Delaware Canal, which is used for recreational activities.

     EPA is seeking to  recover funds spent on its  removal action from eight
parties potentially responsible for wastes associated with the site.

                                Miami, Florida

     The Anaconda Aluminum Co./Milgo 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
and Lower  Miami Springs,  the Hialeah, and the John E. Preston.  An estimated
750,000 people obtain drinking water from wells within 3 miles  of the site.

                                 Hialeah, Florida

     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.  The 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  pretreat-
ment 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-diohlorobenzene, and 1,4-dichlorobenzene in
monitoring  wells on  and off the site and chromium in on-site wells.

     The Biscayne Aquifer 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. Wells in the contaminated area have been taken out of service.

      The BMI-Textron Site covers 1 acre at 1121 Silver Beach Road,  Lake Park,
 Palm Beach County, Florida.  The facility  beqan operation  in October  1969 under
 the name Basic Microelectronics, Inc.  In  December 1980, the site was sold to
 Textron, Inc., and began operation under the name BMI-Textron.  Operations
 stopped in January 1986.

      The facility manufactured chrome-backed glass plates  used  in producing
 electronic components.  The process involved cutting, washinq,  and  polishing
 glass plates before chrome was deposited.  Cyanide was used in  the  qlass-etching
 process.  Liquid waste from the process was discharged to  percolation tonds and
 drain fields under a 4-year industrial waste water treatment permit issued on
 November 17, 1980, by the Florida Department of Environmental Regulation (FDER).
 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, BMI submitted data to FDER 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  and transported
 it to a hazardous waste facility regulated under Subtitle  C of  the  Resource
 Conservation and Recovery Act.

      In January 1986, FDER found cyanide and fluoride in three  on-site monitorinq
 wells and in soil near percolation pond #2.  On November 18, 1986,  BMT-Textron
 agreed to comply with another FDER Consent Order to develop a Plan  to clean UP
 contaminated ground water.  BMI-Textron submitted an "Investigative and Cleanup
 Proposal" on January 6, 1987, in response  to the November  Consent Order.

      Two municipal water systems drawing from wells within 3 miles  of the site
 serve an estimated 108,000 people in Lake  Park, Riviera Beach,  North  Palm Beach,

                               Homestead, Florida

    Homestead Air Force Base is in Bade 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 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 Bade County, which used  it for small commercial and  indus-
trial operations.  In 1953, the Air Force acquired the base and rebuilt it.
                                                    t
    Wastes have been disposed of on-site since the facility's inception.   A
landfill was operated in the 1940s, but little is known about this operation.
During Bade 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). Under this program, established in 1978, 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 1,600 people obtain drinking water and 18,000 acres of farmland  are
irrigated from wells into the aquifer and 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.

                              Madison,  Florida

     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-l,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.

     Woodbury Chemical  Co. occupies 3 acres alono  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-arade
materials in 50-gallon  vats to oroduce pesticides  and fertilizers.

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

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

     The Biscayne Aouifer underlying the site suoolies drinkino water to an
estimated 17,600 residents of Dade County within 3 miles of the site.  FPA has
designated  the  aouifer  under the Safe Drinkina Water  Act as the sole source
of drinking water for Dade County.  A layer of ouartz sand overlies the oolite
limestone of the aouifer; both formations are hiahlv  permeable, facilitatina
the horizontal  and vertical movement of  around 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 Narania Well Field approxi-

     The Woolfolk 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  dichlorobromopropane
into Bay Creek.   Records indicate that the majority  of the waste waters
were 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.,  accjuired 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

    Schofield Barracks, an installation of the  Army Support Command,  Hawaii,
covers 17,725 acres in central Qahu, 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 ICE contamination of drinking
water wells, and reconmended 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.
Under this program, established in 1978, the Department of Defense seeks to
identify, investigate, and clean up contamination from hazardous  materials.

 consists of  four drinking  water wells that are owned and operated by the
 City and County  of  Honolulu.   The wells are located on the Ewa Plain in
 the County of  Honolulu, Island of Oahu, Hawaii.  They are contaminated
 with ethylene  dibromide (EDB)  and trichloropropane (TCP), according to
 analyses conducted  by the  Hawaii Department of Health and other government
 agencies.  The Waipahu Wells  are part of a distribution system which
 serves  13,700  people  in Waipahu, Ewa, and Waianae.  All the wells have
 been closed  down.

      There are several well sites with similar contamination problems
 located in the Schofield Plateau/Ewa Plain area of Oahu.  The City and
 County of Honolulu  Board of Water Supply has conducted pilot tests on
 methods for  decontaminating the water in the area and has had success in
 removing TCP with granulated  activated carbon and with aeration towers.
 However, because of continuing contamination, the people served by the
 Waipahu Wells  are being provided with an alternative supply of drinking
 water.

      Status  (January  1986);  EPA received numerous comments on the six
 sites in Hawaii, which were the first sites proposed for the NPL on the
 basis of contamination that appears  to originate entirely from the
 application  of pesticides  registered under the Federal Insecticide,
 Fungicide, and Rodenticide Act (FIFRA).  EPA is continuing to evaluate
 these sites  in the  context of an overall policy with respect to sites
 at which contamination results from  the application of FIFRA-registered
 pesticides.  Hence, EPA is continuing to propose the sites for the NPL.

      The Board of Water Supply is building a carbon treatment plant at
 the Waipahu  well field. The  treatment plant will be designed to remove
 the pesticides from the water prior  to distribution.  The plant is
 scheduled to be  operational in the summer of 1986.

                             Clinton/Camanche,  Iowa

     Conditions at listing  (October 1984):   The Chemplex Co.  facility is on the
western edge of Clinton and  Camanche,  Clinton  County,  Iowa.   The facility has
manufactured high- and  low-density polyethylene since  1968.   Wastes generated
by this facility include peroxides, mineral spirits, vinyl acetate, and various
organic hazardous substances such  as styrene,  benzene, toluene,  and polyaromatic
hydrocarbons.  Unknown  quantities  of these wastes were disposed  of in an unlined
landfill on the site, which  has  been covered and is no longer used.  Waste
water containing some of these constituents was also stored in a 2-acre lined
impoundment on the site.  During dredging of the sediments from  the bottom of
the impoundment, the liner was ruptured,  releasing hazardous substances.

     The facility received Interim Status under Subtitle C of.the Resource
Conservation and Recovery Act  (RCRA) when the  company  filed Part A of a permit
application.

     Ground water downgradient of  the  landfill and the impoundment is contam-
inated with polyaromatic hydrocarbons  and the  other organic chemicals identified
above, according to tests conducted by the company and its consultants.  The
company has recovered previously released hazardous substances and taken measures
to prevent the release  of additional hazardous substances.  The  company is
conducting additional investigations to completely characterize  releases from
the landfill.

     About 5,000 people depend on  wells within 3 miles of the site as a source
of drinking water.

     Status (January 1986):  Effective December 31, 1984, Northern Petro
chemical Co., now USI Co., purchased substantially all assets of the company.

     The facility has installed  a  system for recovering contaminated ground
water and treating it prior  to disposal.

     In February 1985,  the facility submitted  Part B of  its RCRA permit
application.  EPA is reviewing the application.

     Status (June 1988);  EPA is proposing to  drop Chemplex Co.  from the proposed
NPL.  Because the site  is a  treatment,  storage, and disposal facility, it is
subject to the corrective action authorities of Subtitle C of RCRA.

     On September 19, 1987,  EPA  and the past and present owners/operators
of the Chemplex plant signed an  Administrative Order on Consent  under CERCLA
Section 106.  The order calls for  Chemplex to  characterize an on-site landfill,
sample Rock Creek, which is  downgradient, and  improve  the ground water recovery
system.

     EPA may also pursue cleanup under  RCRA authorities  and will ensure
that the cleanup protects public health and the environment.   EPA can later
repropose the site for  the NPL if  it determines that the owner or operator is
unable or unwilling to  clean up  the site effectively.

                               West Point, Iowa

      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 to 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.

                                 Fairfield,  Iowa

       The Fairfield Coal Gasification Plant 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.  has owned  the  site since 1878.  This company
  was known as Interstate Power Co.  during 1878-1917 and  Iowa Electric Co.  from
  1917 to 1953, when it assumed its  present name.  During 1878-1950, the facility
  produced a natural gas 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 purifi-
  cation of the manufactured gas.  Some of the coal  tar was sold  and some was
  buried in an earthen pit on-site or dumped in a  nearby  ditch.   Disposal methods
  for the iron-cyanide waste are not known, but it may also have  been dumped
  on-site.

       In 1985, Iowa Electric Light  and Power Co.  consultants detected PAHs,
  including benzene, phenanthrene, anthracene, pyrene,  and benzo(a)pyrene,  in
  ground water near the site.  The company is monitoring  ground water quarterly
  to verify that contamination is not reaching private wells within 0.5 mile of
  the facility.

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

       A critical habitat for the slender glass lizard, designated by the U.S.
  Fish and Wildlife Service as an endangered species,  is  within 1 mile of the
  site.

                                  Hospers, Iowa

     The  Farmers'  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.

     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  serve an estimated
1,800 people,  have been replaced with new uncontaminated wells.   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.
The  order provides for a ground water study and completion  of  the RI/FS.

                                     Middletown,  Iowa

    The Iowa Army 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.  The current operating contractor is Mason and Hanger-Silas Mason Co.,
Inc.

    Wastes currently produced at IAPP consist of various explosive-containing
sludges, waste water, and solids; lead-containing sludges; ashes  from
incineration and open burning of explosives; and waste solvent from industrial
and laboratory operations.  The explosives include trinitrotoluene (TNT),
dinitrotoluehe (DNT), and cyclomethylenetrinitramine (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 an abandoned 4-acre settling lagoon at Line 800, which  received
explosive-containing waste water 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
1943-57.  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).

                               Mason City, Iowa

      Lehigh Portland Cement Co.  owns and operates a portland cement
 processing 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 its 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
 (WAWM) 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, WAWM
 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 site.  Wells are  the sole
 source of  drinking water in the area.

      The pH of the surface water (Arch Pond and Blue Waters Pond) averaged
 12.  The Winnebago River is used for recreational activities within 3
 miles  downstream of the site.

      The  Northwestern States Portland Cement Co. (NWSPC) Site covers  35
 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 is very caustic (pH 12.4), according to tests
 conducted by the  Iowa Department of Water, Air, and Waste Management  (IDWAWM)
 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.

                                  Dubuque, Iowa

      The Peoples Natural Gas Co. Site covers  approximately 15 acres in
 downtown Dubuque,  Dubuque County/ Iowa.  A natural gas substitute was
 produced from coal on the site during 1890-1957 by Key City Gas  Co.  In
 the early 1950s, Key City sold out  to North Central Gas,  which was later
 absorbed by Peoples Natural Gas Co.  In the late  1970s, Peoples  Natural
 Gas sold the site to the city of Dubuque, which uses  it as the Dubuque
 Municipal Garage.

      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, the  Iowa Department of Transportation, 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 obtain drinking
 water from municipal wells  within 3 miles of  the  site.

      The Mississippi River  is approximately 500 feet  east of the site.

                                     Keokuk, Iowa

      Sheller-Globe Corp. operated an industrial landfill and solvent burning
 area in Lee County 4 miles north of Keokuk, Iowa, from 1947 to 1970.  The
 5-acre site is in a heavily wooded, rural area.  The land was filled in and
 sold in 1980 to an individual who built a hone 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  diiso-
 cyanates,  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

     The  White Farm Equipment 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.

     White Farm Equipment operated on land leased from  H.  E.  Construction Co.
until  it  filed for bankruptcy in 1980.  Allied Products Co.  purchased the
operation in  late 1986.  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

      She Eastern Michaud Flats Contamination Site covers 2,530 acres in Power
 County,  Idaho, near Pocatello.  Die 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

 elemental phosphorus  from phosphate shale ore on 1,400 acres since 1949.  J. R.
 Simplot  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.   FM3  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. Siiriplot.  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 FMZ 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.

     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.  The  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.

     Qn-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.

     Mountain Hone Air Force Base covers approximately 9  square miles on a
plateau in Elmore County southwest  of Mountain Home, Idaho.   The area around
the base is primarily agricultural.   Hie 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).   Under this  program,  established in 1978, 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 is developing  a  workplan for  a remedial investigation/
feasibility study to determine the  type and extent of contamination at the
base and identify alternatives for  remedial action.  The  workplan is expected
to be completed in the fall  of 1989.

                                Quincy,  Illinois

     The Adams County Quincy Municipal Landfills #2 and #3 are approximately 5
miles east of Quincy, Adams  County, Illinois.   Landfill f2 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 operate as solid
waste disposal sites.

     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,
methane 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 conducted 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 to determine the type  and extent of contamination at the site.

      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 multilavered paper
products.   The waste water and paper fibers generated ao to three unHned sur-
face impoundments.   The paper fiber sediment from the botton of the impoundments
is  spread  on  the ground in accordance with a State permit issued in December
1983.   In  May 1983,  the Illinois Environmental Protection Aqency (TFPA) found
1,1,1-trichloroethane, trichloroethylene, and tetrachloroethylene in sediments
in  the ponds  and in  November 1985 found toluene in pond water.

      On-site  monitoring wells contain 1,1,1-trichloroethane, 1,1-dichloroethane,
and 1,1-dichlorethylene and nearby private wells contain trichloroethvlene,
according  to  tests conducted in November 1985 by Beloit Corp.

      An estimated  15,000 people obtain drinking water from public and private
wells within  3 miles of the site.  The Winnebago County Department of Public
Health, IEPA, and  the Illinois Department of Public Health are workina  together

                    CENTRAL ILLINOIS PUBLIC SERVICE CO.
                           Taylorville,  Illinois

     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 CIPS.  Operations
stopped in  1932.   CIPS sold the property in 1961.

     In producing  a natural gas substitute, the process generated coal
tar, which  contain 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 aboveground 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 the abandoned storage tank at the site.  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
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, CIPS 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.  At the
present time,  in cooperation with IEPA, CIPs is investigating a long-
term solution.

 and 0.5 miles of  the West Branch of the DuPaqe River in DuPage County,
 Illinois.  About  20,000 people live within 3 miles of the site.

      In 1931, Lindsay Light  &  Chemical Co. established a mill in West
 Chicago for the extraction of thorium and nonradioactive elements from
 monazite and other ores.  Later, the site 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.  Cperations at the  site continued until 1973,  when Kerr-McGee, the
 current owner, closed the plant.

      Over  the years,  a portion of the wastes from the plant was discharged
 into Kress Creek, a  tributary of the DuPage River, either via a storm sewer
 or drainage ditch.   Radiation contamination, which is found to a depth of
 several feet along the stream, decreases with distance from the creek.
 Many of the highest  levels are found near the storm sewer outfall.  Water       m
 in the area is obtained from municipal or private wells.                        ™

      The U.S. Nuclear Regulatory Commission issued an Order to Show Cause,
 dated March 21, 1984,  requiring Kerr-McGee Chemical Corp. to either
 prepare and implement a cleanup plan, or show it should not be required
 to do so.

     The MIG/Dewane Landfill cavers 50  acres on Business Route 20E in
Belvidere, Boone County, Illinois.  The site is in a rural area with
contnercial 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 duirped 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.

     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  part of  the plant's National Pollutant Discharge Elimination System.
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-dichlorethylene.

     In 1983,  Winnebago county Public Health 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 approved 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
non- or late  filer under RCRA.  Although the facility was treating, storing,
or disposing  of hazardous waste after November 19, 1980, it did not file a

     Consolidated  Rail  Corp.  (Conrail) has operated a rail yard on County Road  1
at the southwestern edge  of Elkhart,  Elkhart County, Indiana, since 1976.  '
Previously, the 675-acre  property had been a rail yard for New York Central
Railroad  (1956-68) and  Perm 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, tetra-
chloroethylene, 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.

     Tippecanoe  Sanitary  Landfill,  Inc.,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  the shallow
water table and  highly permeable  subsurface materials.  A series of  appeals
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 PCBs.  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

                             Junction City, Kansas

    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.   Most
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
City.  Camp Funston is on the floodplain of the Kansas River, immediately west
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
the Kansas River from the Main Post.  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 Project (IRP).
Under this program, established in 1978, 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.

                         CALDWELL LACE LEATHER CO., INC.
                                 Auburn, Kentucky

     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 disposal
site has received  wastes since 1972.   Until 1985, the site was owned by Caldwell
Lace 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 Lace for the
third  disposal area, a 5.1-acre landfill adjacent to the old trench/lagoon area,
to accept  only solid wastes, including the screenings, fleshings, 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  contaminants can reach surface waters.  The closest
surface water  intake is in  Auburn, approximately 2 miles southeast of the site
where  Black Lick Creek originates.

     The chromium-containing wastes disposed of at the site are inadequately
covered, and the site  is unfenced.  Thus, it is possible for people and animals
to come into direct contact with hazardous substances.

     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.
In February 1985,  the  State approved a plan to close the old landfill.  As part
of the closure plan, Caldwell and  North Park, Inc., monitor surface water and
ground water quarterly.

                    FORT HARTFORD  COAL CO.,  INC.,  STONE QUARRY
                                Olaton,  Kentucky

     Conditions  at listing (June  1988):   The  Fort Hartford Coal  Co., Inc.,
 Stone Quarry  in Olaton, Ohio County,  Kentucky, originally provided limestone
 for parkway construction  in the  western part of  the State.  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 (1)  keep EPA from placing this site and the          M
 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 to  several other potentially responsible parties.

          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 private wells  in the area.  No evidence was
 found indicating contamination from dross stored at the site.  However,  two
 samples had manganese and/or iron concentrations that exceeded Maximum
 Contaminant Levels of the National  Secondary Drinking Water Regulations.

     Recent  estimates indicate 1.2 million tons  of dross are in the quarry.

     On  September 20,  1989, EPA and  Barmet signed an Administrative Order on
 Consent under CERCLA Sections 104(a)(l) and 122(d)(3).  Under this order,
 Barmet  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 Barmet's RI/FS work plan.
 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  in the
 quarry  from water.

                                Maceo,  Kentucky

     Green River Disposal, Inc.,  disposed  of waste on  Kelly Cemetery Road in a
rural area in east Daviess County near Maceo, Kentucky, durina 1970-84.  The
14-acre site was used for landfilling  and  surface disposal.  In January 197%
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 durina
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 Coro., 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 at the facility.

     In June 1985, a site investigation by KDFP 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 19R3, the
facility entered  into an Agreed Order  with KDFP.   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 Bankruptcv
fran the company, under Chapter 7  of  the Federal bankruptcy code.

                           Denham  Springs, Louisiana

     Conditions at listing (June 1986):   The Combustion/ Inc.,  Site covers
approximately 6 acres in Denham Springs,  Livingston Parish,  Louisiana.   Prior
to late 1980, the  company transported  nonreclaimable tars, paraffins,  waste
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 con-
structed;  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 primarily
for storing the wastes before they were processed to recover oil, but  they may
have been used for other storage at times.   In addition, Dubois, 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.  The state is working  with Combustion, Inc., on a workplan for  a remedial
investigation/feasibility study to determine the  type and extent of contamination
at the site.

                       ANNE ARUNDEL COUNTY LANDFILL
                           Glen Burnie, Maryland

     The Anne Arundel  County Landfill covers 130 acres  on  East End  Dover
Street at Route  10 in  Glen Burnie, Anne Arundel County, Maryland.   An
industrial park,  homes,  and a commercial area are nearby.   From  the late
1950s until 1970,  30 acres that were once a gravel pit  served as a  privately
owned open dump.   When the county took over daily operations in  1970, it
capped the old dump with 1-2 feet of clay, planted vegetation, and  installed
50 vents to release methane gas.  Operations stopped in 1982.

     According to a 1978 survey of waste disposal sites by the U.S.  Congress
(the "Ekhardt Report"),  approximately 100 tons of inorganic salts and solids
from Diamond shamrock  Corp.'s plant in Baltimore were deposited  at  the
landfill during  1977-79.

     In August 1983, EPA detected trichloroethylene, dichloroethylene,
and chromium in  monitoring wells at the site.  The landfill overlies a
recharge area of the Patapsco Formation, which supplies drinking water to
municipal and private  wells within 3 miles of the site.  The wells  serve
an estimated 93,000 people.

     The EPA tests also  detected cadmium in Furnace Creek  downstream
of the site.  The creek  is tidally influenced as far as 1.5 miles upstream
of the site.

                                Kalamazoo, Michigan

     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 3.5-mile stretch of the
Kalamazoo River.

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

      In 1986, the Michigan Department of Natural  Resources (MCNR)  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 MCKR,
the contamination begins at the point were Allied's  Bryant  Mill Pond discharges
to Portage Creek.

     MnsiR 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, MCNR began a  long-term project to  clean up  the river after it
was listed in the Michigan Environmental Response  Act.  MCNR  has  conducted
extensive sampling to determine the  extent of contamination.

     On December 2, 1987, the State  filed a complaint under CERCLA  Sections
107 and 113, the Resource Conservation and Recovery  Act, th£  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.

                            Sault Sairrte 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 ciiromium,  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);   Algoma Steel has fenced the site.  EPA is conducting
a remedial  investigation/feasibility study to determine the type and extent of
contamination at the site and identify alternatives for remedial action.

     ' Ford Motor Co.  operated an aircraft bomber plant for the Federal
Government during World  War II 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 Comiission,  which operates the Willow Run Airport.  The
abandoned lagoon is  on airport property.

     Ford Motor disposed of approximately 1 million cubic feet of sludge
in the lagoon, according to information the centrassion provided to EPA as
required by  CERCIA section 103(c).  Analysis of the sludge conducted 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

     Conditions at listing  (June 1988);  Peerless Plating Co. operated an
electroplating shop on a 1-acre site at 2554 Getty Avenue in Muskegon,  Muskegon
County, Michigan, during 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  diffi-
culties.

     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.  MENR also determined that  manholes inside the plant
discharged directly onto the ground and that drummed  wastes were stored on-site.

     In Septentoer-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-l,2-dichloro-
ethylene, 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  (December 1988);  EPA's preliminary plan  for fiscal year 1989
includes a remedial investigation/feasibility study to determine the type and
extent of contamination at  the site and identify alternatives for  remedial

                            Cannon Falls, Minnesota

      The 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, Dakhue Landfill, Inc., has had a permit  from the

 estimates that through 1986, 817,000 cubic yards of solid waste  (primarily
 nonhazardous industrial and municipal wastes) 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
 600 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 sloping
 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 follow 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, Dakhue Landfill, Inc., declared bankruptcy under
 Chapter 7 of the Federal bankruptcy code.

                              St. Charles, Missouri

      Conditions at listing (October 1984);  Findett Corp. operates on a site
 near the St.  Louis suburb of St. Charles, St. Charles County, Missouri, in  the
 floodplain of the Mississippi River.   The Findett facility covers about 3 acres;
 however,  contamination originating at the facility may cover a much greater
 area.  A municipal well field is within 1 mile of the site.

      Among its activities, Findett reprocessed fluids containing PCBs during
 1963-74.   Some wastes from the reprocessing were disposed of in a small pond
 on the Findett property.  In 1977, after significant levels of PCBs were
 detected in the pond, Findett excavated and backfilled a portion of the pond.

      In further investigations in 1979, EPA found that the pond area was still
 contaminated with PCBs.  As a result, EPA issued an Administrative order under
 the Clean Water Act in 1980 requiring further excavation of the pond area.
 Additional sampling after the excavation indicated PCBs had migrated beyond the
 immediate pond area and into subsurface areas.

      The facility received Interim status under Subtitle C of the Resource
 Conservation and Recovery Act (RCRA)  when the company filed Part A of a
 permit application for treating and storing hazardous waste.

      EPA issued an Administrative Order on Consent under Section 3013 of
 RCRA in September 1982.  The order required Findett to design and implement
 a monitoring, sampling, and analysis plan to characterize the nature and
 extent of PCB soil contamination, as well as the potential for ground water
 contamination in the immediate vicinity of the Findett facility.  Findett
 installed monitoring wells and analyzed ground water for PCBs.

      Status (January 1986):  EPA sampled wells in June 1985, identified other
 contamination in ground water beneath the site, and developed 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.   EPA is negotiating with Findett to conduct the RI under a CERCLA
 Section 106 Consent Order.

      Status (April 1988):  EPA is proposing to drop Findett Corp. from the
 proposed NPL.  Because the site is a treatment, storage, and disposal facility,
 it is subject to the corrective action authorities of Subtitle C of RCRA.

      A Superfund-financed RI to determine the extent and possible source of
 ground water contamination began in August 1987 after Findett declined to do
 the work.  Field work has been completed.  Analytical data are being evaluated,
 and a draft RI report should be available shortly.

      EPA may also pursue cleanup under RCRA authorities and will ensure
 that the cleanup protects public health and the environment.  EPA can later
 repropose the site for the NPL if it determines that the owner or operator
 is unable or unwilling to clean up the site effectively.

     The Oronqo-Duenweg Mining Belt is in Jasper County,  Missouri,  and is
considered part of the Tri-State Mining District of Missouri,  Kansas, and
Oklahoma.  Two other sites in the district—Cherokee  County in Kansas and Tar
Creek in Ottawa County, Oklahoma—were placed on the  NPL  in September 1983.
Superfund-financed remedial  activities are  under way  at these  two sites.

     Lead and zinc ores, as  well as some cadmium ores, were mined from 1848 to
the late 1960s, with the greatest activity  occurrina  in an area  of 2 by
10 miles between Oronogo and Duenwea, northeast of Joplin.   Minina efforts were
originally performed by one- to two-man independent operations that in later
years were organized by several area minina companies.

     The site is honeycombed with underground workinas, pits,  shafts (open,
closed, and collapsed), mine tailinas, waste piles, and ponds  holdina tailina
waters.  An estimated 10 million tons of wastes or tailinas are on the site.

     Throughout the mining era, around water had to be pumped  to prevent
flooding of mines.  When mining ceased, the shafts and underaround workinas
filled with water.  Tailing  piles have been left uncovered and unstabilized.
Leachate and run-off from the piles can enter open shafts and  pits.

     Ground water and surface water on the  site are contaminated with cadmium,
lead, and zinc, accordina to tests by the U.S. Geoloaical Survey in 1977.   An
estimated 1,500 people  obtain drinkina water from private wells within 3 miles
of the site.

     This mining site is potentially eligible  for cleanup funds from the State
of Missouri's approved  program under the Surface Mining  Control  and Reclamation
Act of 1977  (SMCRA).  EPA is developina a policy for  listina such sites.  This
site is being proposed  for the NPL at this  time to avoid  delay in startina
CERCLA activities.

                            Gray Summit, Missouri

       Conditions at listing (September 1983);  Quail  Run Mobile Manor is a
  trailer park located 2 miles east of Gray Summit/  Franklin County,
  Missouri.   In the early 1970s, the road through the  park  was  sprayed with
  an unknown quantity of dioxin-contaminated waste oil.   In 1974, sane of
  the soil was excavated from the road and deposited in  the area between
  the road and a lagoon and also on two nearby properties which are also part
  of the site.

       Early in 1983, EPA identified dioxin in soil  samples from numerous
  locations  on the site, one as high as 1,100 parts  per  billion.   As  a
  result, the U.S. Centers for Disease Control (CDC) issued a health  advisory
  warning that the more than 100 residents were at risk  of  developing adverse
  health effects from dioxin if they remained in their homes.   Some of the
  residents  had come to the trailer park from Times  Beach,  Missouri,  which
  also has a dioxin problem.

       In May 1983, EPA, the Federal Emergency Management Agency (FEMA),
  and the State briefed the residents on the findings  and explained FEMA's
  offer of temporary relocation.  Of 33 families, 29 applied for relocation.
       Status (July 1984);  A few families are still residing  at Quail  Run.
 The  site is scheduled to be cleaned up as part of a planned  removal using
 CERCLA emergency funds.  The project involves excavating and restoring
 several on-site areas contaminated with dioxin.  The contaminated  soil
 will be stored temporarily on the site.

       EPA is deferring final rulemaking on this site because  it does not
 meet the criteria currently specified to place a site on the NPL.  EPA
 is considering revising the National Contingency Plan (NCP),  the Federal
 regulation by which CERCLA is implemented, in such a way that Quail Run
 and  similar sites where CDC has issued a health advisory will qualify
 for  the NPL.

       Status (January 1986);  Removal actions are currently underway.   All
 families have been temporarily relocated, and all of the mobile homes
 have been decontaminated and sent off-site for rehabilitation.  The tasks
 remaining under the removal action include construction of one  remaining
 steel structure of a total of 11 for temporary storage of contaminated
 soil; excavation and storage of remaining contaminated soil;  and site
 restoration.

       On Sept* 16, 1985, EPA revised the NCP to allow placing  Cuail Run
 and  similar sites on the NPL.  EPA is continuing to evaluate  this  site
 and  so is again deferring final rulemaking.

                                   Bridgeton, Missouri

    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  (MDNR) closed the
unregulated landfill.  Since then, MDNR has issued several permits for various
portions of the 200-acre site.  Currently, an operating sanitary landfill has
a  permitted area of  52 areas,  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.

                           Gautier,  Mississippi

     The Gautier Oil  Co., Inc., Site covers 3 acres in Gautier, Jackson
County, Mississippi.   The site is an abandoned wood-preserving and oil
recovery facility that operated for  104 years under different owners/
including Delta  Creosote  and Gautier Oil Co., Inc.  Operations ceased in
1983.  The current  owner  is  Seaboard Systems Railroad, Inc.

     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 by Consent to
Seaboard under CERCLA Section 106(a) to remove contaminated soil, waste,
containers,  and  equipment from the site.  Seaboard removed over 536 tons
of materials from the site and transported them to a hazardous waste
facility regulated  under  Subtitle C of the Resource Conservation and Recovery
Act.

         BURLINGTON NORTHERN RAILROAD  (SCMERS TIE-TREATING PLANT)
                             Somers, Montana

     Conditions at listing  (October 1984);  Burlington Northern Railroad has
treated ties on a 4.5-acre  site  in Somers,  Flathead  County,  Montana,  since
around 1900.  The plant's current operations are regulated under Subtitle  C
of the Resource Conservation and Recovery Act  {RCRA).   An old waste disposal
lagoon downgradient of  the  RCRA-regulated  facility has not been used since 1974.

     The old lagoon was used to  dispose of  creosote  wastes from the wood-
treatment process.  The wastes were discharged  from  the pond via a ditch to a
marshy area on the shore of Flathead lake,  the  largest fresh water lake west of
the Mississippi River.  The lake is extensively used for camping and fishing,
and towns along the lake such as Somers use it  for drinking water.

     On February 28, 1984,  the State dug several shallow holes along the lake
shore and took samples  of creosote-saturated sand below the ditch outfall.
Sludge/sediment samples were collected from the bottom of a 0.5-acre swamp
pond located along the  shore adjacent to the waste ditch.  The material was
silty-sand and stained  with oil.

     Early in March  1984, consultants to Burlington  Northern drilled approxi-
mately 60 test borings  in the vicinity of  the  swamp  pond, in the waste ditch,
and below the seasonal  high water beach of  Flathead  Lake.  About 46 percent of
the test holes showed visual evidence of creosote contamination.  The holes
encompassed an area of  approximately  3.5 acres, including the pond.  Soil
samples were collected  from the  test borings.   Monitoring wells were installed
at 10 sites around the  pond.

     Status (January 1986); In  May and June  1985, Burlington Northern removed
contaminated sludge, soil,  and water  from  the  swamp pond under a CERCLA Section
106 Consent Order for an immediate removal. The materials were placed in two
existing RCRA lagoons on the plant site which  were reconstructed to meet RCRA
standards.   The company is moving the sludges and soils to another of its
facilities at Paradise, Montana, where they are being placed in a waste pile
that meets RCRA standards.  Swamp pond water was processed through the plant's
waste water recycling system.

     In December 1984,  Burlington Northern voluntarily submitted to EPA a study
to determine the type and extent of contamination at the site and identify
alternatives for remedial action.  On October  9, 1985, EPA and Burlington
Northern signed a Consent Order  under CERCLA  Section 106 for a remedial investi-
gation/feasibility study (RI/FS) covering  the  old lagoon.  The RI/FS activities
are scheduled to be completed  in approximately January 1987.

     Status (June 1988);  EPA  is proposing to drop Burlington Northern
Railroad's Somers Tie-Treating Plant  from  the  proposed N?L.  Because the
site is a storage and disposal  facility,  it is subject to the corrective action
authorities of  Subtitle C of RCRA.

     Burlington Northern is closing the  two existing RCRA lagoons according to
a RCRA closure plan  approved by the State.  1fte company has  submitted a draft
RI/FS and Endangerment  Assessment  report  to EPA for the old  lagoon.  Late  in
1988, the public will have  an  opportunity to comment on the  cleanup alternative
recommended in  the draft RI/FS  report.

     EPA may also pursue cleanup under RCRA authorities and  will  ensure that
the cleanup protects public health and the environment.  EPA can  later  repropose
the site for the NPL if it  determines that the owner or operator  is unable  or
unwilling to clean up  the site effectively.

                                Billings,  Montana

      The Comet Oil Co. Site covers  approximately 10 acres on Frontage Road in a
 residential/industrial part of Billings,  Yellowstone County, Montana.  The
 facility opened approximately 25 years ago and functioned as a one-person waste
 oil re-refinery operation until  Bair's, Inc.  (also known as Mountain States
 Petroleum  Corp.) purchased  it in 1974.  In 1979, Bair's ceased operation for
 economic reasons.

      A large number  of storage tanks and empty 55-gallon drums are on-site, as
 well as several waste oil lagoons and a large  sludge pile.  In 1985, 100,000
 gallons of contaminated waste oil spilled when vandals opened valves on one
 tank.  Under the supervision of  the Montana Department of Health and Environ-
 mental sciences, Comet collected 75,000 gallons of waste oil from the site and
 a neighboring property; the other 25,000 gallons were lost to the environment.
 Comet also covered parts of the  site with 3-5  feet of soil.

      Organic compounds, including benzene, phenol, 2,4-dimethylohenol, naphtha-
 lene, and  trans-l,2-dichloroethylene, are present in an off-site downaradient
 monitoring well, according  to EPA tests conducted in 1985.  Petroleum products
 and solvents are in  soils throughout the site, to a depth of 34 feet in some
 parts, according to  EPA.  Within 3  miles of the site are four municipal wells
 and one private well that supply drinking water to at least 5,^00 people.

      Contaminants at the site threaten the Yellowstone River, which is
 used for recreational  activities.   The river is 0.6 mile downstream from

                             Goldsboro, North Carolina

     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
of 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 PCB-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 Comnunity Development  (NRCD).
In August 1985, EFA 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.

                               Columbus, Nebraska


     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  Laup River.   The site boundary is defined 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.   Among 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 under Subtitle C of the
Resource  Conservation  and Recovery Act as small quantity generators of waste
containing  tetrachloroethylene.   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
use.  All wells tap the surficial aquifer consisting of alluvial sands and
gravels;  the  water  table is at a depth between 12.4 and 30 feet.

     The  former Nebraska Ordnance Plant once occupied over 17,000 acres near
Mead 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 also was 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 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 currently is owned
by the Nebraska National Guard and numerous 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 TNT and 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 from wells within 3 miles of the

                FEDERAL AVIATION ADMTNISTRATICN TECHNICAL CENTER
                          Atlantic County, New Jersey

    Die Federal Aviation Administration  (FAA)  Technical Center covers 5,052
acres 8 miles northwest  of Atlantic City in Atlantic County.   The site borders
the Garden State Parkway in southeastern New Jersey.  Installations on the site
include the Atlantic City International  Airport, a New Jersey Air National
Guard Station, and extensive FAA facilities.

    Activities at the  site started in 1942 with construction of a Naval air
base.  In late 1958, FAA, then known as  the Airways Modernization Board, took
over the operation and has used  the facility as an airport and aviation safety
research center.

    In 1984, the New Jersey Department of Environmental Protection (NJDEP)
contracted for an assessment of  pollution  sources that may 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 Lab  (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 (RI/FS) under NJDEP and EPA guidance.

                               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 NPL in June 1988.

     In 1981, as required by CERdA Section 103 (c), FMC  Corp. reported to
EPA that in 1974 its  Princeton plant had deposited approximately 61,000 cubic
feet of chemical waste  containing heavy  metals,  organic  solvents, and pesticides
at 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 (November 1988):  EPA is considering various alternatives for the
site.

                              Lodi, New Jersey

     Conditions  at  listing (October 1984):  The 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 is 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 contaminants.

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

                              Colts Neck, New Jersey

        Conditions  at  listing (October 1984):  The Naval Weapons Station
   Earle covers  10,048 acres in Colts Neck,  Monroouth 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  ammunition, 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  29 waste areas identified by the Navy.  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.

        The waste areas of Site A overlie the Cohansey Sand, Kirkwood
   Formation, Vincentown Formation, Red Bank Sand, Navesink Formation,
   and the Wenonah  Formation aquifers.  All are hydraulically connected, so
   that water can move among them.  An estimated 1,900 people within 3
   miles of Site A  are served by these aquifers.  Local surface water is
   used for recreation and irrigation purposes.  An estimated 270 people
   are served by surface water within 3 miles downstream of Site A.

        The station is participating in the Installation Restoration Program,
   the specially funded program established in 1978 under which the-Depart-
   ment of Defense  has been identifying and  evaluating its past hazardous
   waste sites and  controlling the migration of hazardous contaminants from
   these sites.  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 13 of the 29 areas.

                            LEE ACRES LANDFILL (USDOI)
                              Farmington, New Mexico

     The Lee  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.   The Giant Industries, Inc., refinery property is to
the  southeast.

     On May 1,  1962,  the Bureau of Land Management (BLM), 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 septage, 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.  BLM 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.  BLM ordered the landfill closed and, when the
county  abandoned  it,  contracted for fencing.

     In 1985, BLM 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, BLM arranged for alternative drinking
water supplies for  residents of Lee Acres using ground water.  BLM plans to
hire a  contractor in  1988 to conduct a remedial investigation to determine the
type and extent of  contamination at the site.

                            Prewitt, New Mexico

      The Prewitt Abandoned Refinery Site occupies 75  acres just east of Prewitt
 on U.S. Highway 65 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 Refininq
 Co., Petroleum Products Refining and Producina Co., Malco Refineries, New Mexico
 Asphalt and Refining Co., Malco  Asphalt and  Refining  Co., and Fl Paso Natural
 Gas Products Co.  The Navajo Indian Tribe has owned the  property since December
 1966.

      According to information provided to EPA under CERCLA Section 103(c),
 El Paso Natural Gas Products Co. deposited crude refinery wastes at the site
 and Petroleum Products Refinery  and Producinq 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  svstem, a oublic noncommunity

                            CARSON RIVER MERCURY SITE
                         Lyory'Qiurchill Counties, Nevada

       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 mined 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.  Ifeese conditions facilitate movement of
  contaminants 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.

                                Lisbon, New York


     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 landfarming operation.  The site
stopped operating in 1981.

     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  1986-88  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 contain
low  levels  of  PCBs,  and that contaminants are migrating 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.

    The Seneca Army Depot encompasses more  than 10,000 acres in Seneca County, New
York.  It lies between Cayuga and Seneca Lakes  in the Finger Lakes region and
abuts the town of Romulus.  Tne 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).  Under this program, established  in  1978, the  Department of Defense seeks to
identify, investigate, and clean up contamination 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         I
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 depot.

     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-methylnaphthalene, 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

     Kerr-McGee  Corp.'s Gushing Plant covers 116 acres in Gushing,  in a  rural
area of Payne County,  Oklahoma.  Since 1915, numerous oil and pipeline
companies have occupied various portions of the site.  In 1956, Kerr-McGee
acquired a  refinery  on the site and operated it until 1972.  During 1963-65,
Kerr-McGee  conducted various uranium processing operations  in a plant on the
site for the Atomic  Energy Commission (AEC).  From early 1965 until February
1966, Kerr-McGee produced thorium metal from thorium nitrate provided by AEC.
After operations ceased in 1966,  the plant was demolished.  In 1972,  soil and
wash water  containing thorium were placed in an on-site surface impoundment
known as Pit 4.   A number of other impoundments  (Pits 1, 2, 3, and  5)  contain
acid sludges and oily wastes from the oil operations; the pits were filled in
prior to 1956.

     In 1986, EPA detected uranium, radium, chromium, nickel, zinc, and

                UNION PACIFIC  RAILROAD CO.  TIE-TREATING PLANT
                              The Dalles, Oregon

     The Union  Pacific Railroad Co.  Tie-Treating Plant covers 83 acres in a
mixed 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-McGee 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  anmoniacal copper arsenate, creosote,
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, and arsenic  are the major contaminants  found in soil and ground water
at the site.  Contamination  by arsenic and  volatile organic compounds is
greatest in the shallow and  intermediate aquifers beneath the site.  Organic
contaminants, such as 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 City of 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  and  agreed to undertake 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 by mid-1991.

                         Dublin Borough, Pennsylvania

     The Dublin TCE Site  covers approximately 4.5 acres in Dublin Borough,
Bucks County,  Pennsylvania.

     In June  1986,  the Bucks County Health Department discovered
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.; Kollsman 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, but no evidence has been found to
date to suggest that either this company or Mr. Thompson used or disposed of
TCE on  the  property.

     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 CERCLA  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 to study
soil and ground water at  the site.

                             OHIO RIVER PARK
                      Neville Island, Pennsylvania


        The 32-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.

                         LONGHORN ARMY A1VM1NITION PLANT
                                 Karnack, Texas

    Longhorn Army Ammunition Plant  (LAAP) covers 8,490  acres between State
Highway 43 and Caddo Lake in KarnaOc, Harrison County,  Texas.  The area is
primarily rural.  Established in 1941, LAAP 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 now placed in drums and stored  in separate areas until disposal  is
arranged.

    LAAP 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  substances.
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 LAPP.  The nearest well is 500 feet
from LAAP'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 LAAP:   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.

                                 Fort Worth, Texas

     Conditions at listing (October 1984):  Air  Force  Plant #4  occupies approxi-
mately 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 via  the National Response Team 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 con-
structed a french drain and a collection basin at the  outfall.   Since that time,
leachate frcm the drain and outfall has  been collected, stored, and disposed of in
an EPA-approved disposal  facility.  In 1983, the Air Force removed 21,300 cubic
yards of contaminated soil frcm closed waste pits and  disposed  of the soil at an
approved 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 qround water
in the upper  zone under the site  is contaminated with  several organic chemicals
and heavy metals.  Several deeper wells  were drilled at the site into the Paluxy
aquifer, which  is the source of drinking water for nearby residents, including
the municipality of  White Settlement  (population 13,420).  Two wells have been
found to be contaminated  by 1,2-transdichlorethylene and trichloroethylene.

     The plant  is participating  in  the Installation Restoration Program, the
specially  funded program  established  in 1978 under which the Department of Defense
has been identifying and  evaluating  its  past hazardous waste sites and controlling
the migration of hazardous contaminants from these sites.

     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  (April 1987);  Phase II (preliminary survey) of the Installation
 Restoration Progran is underway.

      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 RCRA.  EPA is
 soliciting comments on the Hazard Ranking  System  score  for the sites, which
 includes areas subject to RCRA Subtitle C  corrective  action authorities.

                             Lawrenceburg,  Tennessee

     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 adiacent
to Shoal Creek.  Prior  to about 1956, a hydroelectric plant owned by the City
of Lawrenceburg operated on  the site.
     Murray-Ohio Manufacturing  Co.  records  indicate that, beginnina about
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 sprinq of 1^63, 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 durina
or shortly after the fire.   The site was apparently abandoned after the fire
and has since been used only for  occasional dumpinq of household trash.  Tn
recent years, access to the area  has been restricted bv a landowner across
whose property the road to  the  site passes.

     In an inspection in  1983,  the  Tennessee Division of Solid Waste Manaaement
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
the ground water is  shallow (4  feet).  These conditions facilitate movement of
contaminants into ground  water.   The City of Lawrencebura obtains cart 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,non
people obtain drinking water from wells and sprinqs within 3 miles of the site.

     Downstream of the dump, Shoal  Creek is used for fishinq, 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.

                            Sioux Falls, South Dakota

     The Williams Pipe Line Co. Disposal Pit is in the northeast corner of the
company's  12th Street terminal in Sioux Falls, Minnehana County, South Dajcota.
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'-DDD,  4,4'-DDT, gamma-
chlordane, beta-BHC, and lead, according to EPA tests conducted in 1989.  An
estimated  100,000 people in the Sioux Falls area obtain drinking water from
two  sets of public wells within 3 miles of the site.  One well is  about 1.25
miles to the  southeast.

three sides and residentiaI/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.   Under this program,  the Department of

contaminated areas have been identified;  the Air Force is investigating 8 —
the 5 EPA evaluated, plus an additional landfill,  hydrant fuel lines, and the
old auto hobby shop.

     On-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

                         Simpsonville, South Carolina

      Para-Chan Southern, Inc., has manufactured organic solvents and adhesives
 on a 100-acre site near Sinpsonville,  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 wells; 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

                             Sharon, Pennsylvania

     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.

     Soils  at the site are permeable and ground water shallow (5 feet in some
cases), conditions  that facilitate movement of contaminants into 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.

    Tbbyhanna Army Depot covers 1,408 acres in Tobyhanna, Monroe County, in
the Pocono Mountains of northeastern Pennsylvania.  Military operations
started on the site in 1902.  It assumed its present name in August 1962.
The depot's primary mission is to provide maintenance  and supply support to
the Army.  The 117 buildings on the depot include metal  refinishing, electronic
fabrication, electroplating, and degreasing operations,  as  well as waste water
treatment plants, a hazardous waste storage area, and  a  landfill.   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).  Under  this program, established  in  1978, the Department of
Defense seeks to identify, investigate,  and clean up contamination from hazardous
materials.  IRP investigations conducted in 1981 and 1986 found trichloroethylene
(TCE) and cis-l,2-dichloroethylene in on-site  monitoring wells, and TCE and
tetrachloroethylene  in on-site and off-site water supply wells. An estimated
5,000 people obtain drinking water from depot  and private wells within 3 miles of
hazardous substances on the depot.

    Army tests conducted in 1986  found  cadmium in soil in the plating shop area    4B
and in sewage treatment  sludge.  The sludge was  in  a swamp  that drains to the south™
to Cross Keys Run and  to the north to an unnamed tributary  to Gouldsboro Lake.
The lake, which is within 3 miles downstream of  the landfill, is used for
recreational activities.  Oakes Swamp is within  1 mile of the landfill.

    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 remaining waste  areas.

      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 Olean Tile Go., 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 Olean discovered two
 10,000-gallon tanks.  According to tests conducted  by the  company and
 the Pennsylvania Department of Environmental Rssources (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.  Two monitoring wells were also installed  as
 part of closure.

      The downgradient monitoring well on-site is contaminated  with
 trichloroethene, boron, arsenic, and cyanide, according to EPA analyses.
 An  estimated 54,000 people draw drinking water from public (North Penn

 communities 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 Environ-
 mental 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  and SEPTA to determine the extent of contamination and
 correct any problem areas.  Amtrak and SEPTA took actions primarily involving
 collection  of samples, some cleanup efforts, and further study.

      In November 1985, analyses of samples taken in July 1984 by a consultant
 to Amtrak and SEPTA were made available to EPA.  The results indicate a severe
 PCB problem, with soil contamination ranging as high as 3 percent and to depths
 of up to  3  feet in the yard.

      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 in Federal court under the
 Toxic Substances control Act, CERCLA, and the Resource Conservation and Recovery
 Act.  The complaint sought an order requiring Amtrak and SEPTA 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.  An agreement
 was reached that required Amtrak and SEPTA to install a security fence as a
 preliminary measure.

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

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

      After  this site was proposed in January 1987, new technical information
 became available.  Hence, EPA is  reproposing this site to allow  an additional
 60-day comment period.

     The Rio Grande Oil Co. Refinery covers approximately 11 acres west of Ann
Street  in Sour  Lake, 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.   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.

      The Tex-Tin Corp. Site covers 128 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").

      On the site are the following hazardous waste units:  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 1985, 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.

      This mining site is being proposed for the NPL because it  is a noncoal
 site with mining operations that occurred after August 3, 1977, the enactment
 date of the Surface Mining Control and Reclamation Act (SMCRA).  Thus, the site
 is neither regulated by SMCRA nor eligible for funds from the SMCRA Abandoned
 Mine Land Reclamation Program.

       The Midvale Slag  Site covers 300 acres in Midvale, Salt Lake
  County, Utah.  Midvale (population 10,000) is part of the Salt  Lake
  City Metropolitan area (population 936,000).  Between 1902 and  1971,
  United States Smelting,  Refining and Mining Co. smelted ores on the
  site to produce copper,  gold,  lead, and silver.  The site consists of
  piles of slag estimated  at 2 million tons that remain frcm the  smelting
  operations.  The smelter no longer exists.  In 1971, Valley Materials,
  Inc., acquired the  site  and processes the slag into materials for
  railroad beds and asphalt highways.

       Testing by the Utah Department of Health indicated that the slag
  contains high concentrations of arsenic and heavy metals.  The  slag  is
  found on the surface and down  to a depth of 20 feet.  Hence there is a
  potential for ground water contamination.  Several municipal wells serving
  an estimated 38,000 people are within 3 miles of the site.

       The Jordan River, which forms the western boundary of the  site, is
  not contaminated to date,  according to tests conducted by EPA in May
  1985.  However, slag piles are as close as 50 feet to the river, causing
  concern that the river can becone contaminated.

                               Summit County, Utah

      The Richardson Flat Tailings cover approximately 160 acres in a valley
 1.5 miles from most recent  development  in the  town of Park City, summit County,
 Utah.  At least 2 million tons of tailings are on-site.

      The mill tailings came from the Keetley Ontario  Mine and other metal
 mining operations currently owned by United Park City Mines (UPCM).  The most
 recent use of the area for  tailings disposal was during 1975-81, when UPCM
 leased its mining properties  to either  Park City Ventures or Noranda Mining,
 Inc.  The two companies constructed and operated milling facilities on UPCM
 properties.

      Both the Utah Department of Environmental Health and EPA have investiqated
 the site in the past  3 years.  The results show that  the heavy metals and
 arsenic present in the tailings have migrated  into the soil below the tailinas,
 ground water, surface water,  and air.   Continued migration is likely because
 the piles are unlined and uncovered.  Elevated concentrations of arsenic, copper,
 and lead were detected in Silver creek  downgradient of the tailinqs.  Water
 diverted from Silver  Creek  is used to irrigate oastureland and hay fields within
 3 stream miles of the site.

      High-volume air  sampling at Richardson Flat Tailinas documented that
 arsenic, cadmium, lead, and zinc were released to  the air.  An estimated 4,<^no
 people live year-round within 4 miles of the tailinqs.

      Motorcyclists commonly ride on the site,   in  addition, airborne tailinqs
 material blows across Highway 40 on a daily basis  durinq the summer months.

      This mining site is potentially eligible  for  cleanup funds from the State
 of Utah's approved program  under the Surface Mining Control and Reclamation Act
 of 1979 (SMCPA).  EPA is developing a policy for listing such sites.  This site
 is being proposed for the NPL at this time to avoid delay in startinq CTRCLA

     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  fron 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 coop-
erative agreement between EPA and the State of Utah. "The State has a
contractor to perform a" remedial investigation/feasibility study to
determine the type  and extent of contamination at the site and  identify
alternatives  for  remedial action.

     This mining  site is not being placed on the NPL at this time because
it ceased mining  before Aug. 3, 1977, the enactment  date  of the Surface
Mining  Control and  Reclamation Act (SMCRA).   Therefore, it may  be eligible

        Conditions at listing (October 1984);  The Tooele Army Depot  (TEAD),
   Tooele, Tooele County, Utah, 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.

        TEAD's mission is fourfold: 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 TNT and RDX,  an
   experimental explosive, in soil near the TNT Washout Area, threatening
   ground water.  About 2,500 people depend on ground water within 3  miles
   of the site as a source of drinking water.

        TEAD is participating in the Installation Restoration Program, the
   specially funded program established in 1975 under which the  Department
   of Defense has been identifying and evaluating its past hazardous  waste-    (
   sites and controlling the migration of hazardous contaminants from these
   sites.  The Army has completed Phase I (records search).

                            Salt Lake City, Utah

     The Wasatch Chemical Co.  (Lot 6) Site covers 6 acres  in Salt: Lake City,
Salt Lake County, Utah.  Wasatch began  formulating various organic chemical
products, including pesticides, on 15 acres in  the early 1960s.   Subsequently,
the site was subdivided into parcels of 6 and 9 acres, which are now owned
by two separate entities.  Lot 6 has not been used since before  1980.

     The Utah Department of Health estimates  that approximately  2,300 cubic
yards of wastes have been disposed in a concrete  pond and  in drums on Lot
6.  During an inspection in June 1985,  the  State  found 48  drums  holding
ignitable and reactive liguids and 13 pressurized gas cylinders  in poor
condition; several of the drums were leaking.   Residential and commercial
industrial areas are within a few hundred yards of the drum storage area.
Approximately 85,000 people live within 3 miles of the site.

     Additional wastes from the operation were  discharged  into the 700
Wast Stream, a ditch that drains into the Jordan  River.

     Tests conducted by the State in June 1985  detected  several  chemicals,
including pesticides and methyl isobutyl ketone,  in ground water.  700
West Stream also has elevated levels of some  of these compounds.

     About 60,000 people obtain drinking water  from private wells within
3 miles of the site.  The nearest well  is within  2,000 feet. No alternative
source of water is available in the area.  The  Jordan River/Surplus Canal
is used primarily for industrial, irrigation  (3 sguare miles), and
recreational purposes.

     In January 1986, the State reguested the owner of Lot 6 and a number
of other parties potentially responsible for  wastes associated with the
site to remove drums and other materials from Lot 6.  When they  refused,
the State filed an action in Federal Court seeking the potentially responsible
parties (PRPs) to remove the drums and  compensate the State for  its costs.
In February 1986, the State and EPA negotiated  a  Consent Order under CERCLA
section 106 for the drums.

     In April 1986, during a CERCLA emergency removal action, EPA detected
dioxin in drums, standing water, and soil on  the  site.   In the removal
action, EPA (1) excavated eontaminated  soil,  (2)  transported non-dioxin
drums and soil and the cylinders to a hazardous waste landfill permitted
under the Resource Conservation and Recovery  Act, and (3)  placed dioxin-
contaminated materials in a temporary storage unit adjacent to Lot 6.  EPA	
has reached a partial agreement with several  PRPs to pay for a portion of
the emergency action.  The PRPs have also agreed  to provide and  maintain a
storage facility for the dioxin materials pending final  disposal.

                              Portsmouth, Virginia

     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 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 indicate that breathing-zone air contains 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.

                            Silverdale, Washington

    The Bangor Naval Submarine  Base  covers 7,000 acres  on Hood 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). 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  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), trinitrotoluene (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 Canal
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.

                             Oentralia, Washington

     Conditions at listing  (June 1988);  The 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 the
lower aquifer within 3 miles of the site.   Surface water is used for
irrigation.

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

     Status  fDecember  1989);  WDOE has approved the  city's plan for closing
the landfill under state regulations.  The city has  made temporary
inprovements to the  landfill's  system  of ditches for collecting leachate and
storm water and installed three additional monitoring wells.  The city is
monitoring ground water on  a quarterly basis.

                              Kent,  Washington

     The Seattle  Municipal  Landfill (Kent 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 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.

      Tosco Corp.'s Spokane Terminal covers 50 acres in an  industrial  area 1.5
 miles  north  of Spokane,  Spokane County, Washington.  The site  is  a bulk storage
 tank farm  for petroleum  products.   An oil refinery was on  the  site when Tosco
 purchased  it in  1976.  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 Sookane
 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 Ecoloov
 tests  conducted  in 1986.  The soil overlyinq the aouifer is highly permeable,
 which  facilitates movement of contaminants into ground water.   Ground water
 within 3 miles of the site provides drinking water to over 200,000 people and
 is  also used for  irrigating croplands.

                               DePere,  Wisconsin

      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.  The 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.

                       FORT  HOWARD PAPER CO.  SLUDGE LAGOONS
                              Green Bay, Wisconsin

     Fort Howard Paper Co.  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 contamination  cannot be con-
clusively 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.

                        MYSTERY BRIDGE ROAD/U-S. HIGHWAY  20
                                Evansville, Wyoming

       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 contamination have been  identified
  at the site, which covers approximately  200 acres.

       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 was replaced in December 1984 by a concrete-lined  structure
  with a capacity of about 700 cubic yards.  The pit  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  to the
  north of the pit, including private wells in the Brookhurst subdivision.   Within
  3 miles of the site, this aquifer is the sole source of drinking water  for
  about 400 people, an alternate source for about 2,500 people,  and a source of
  water to irrigate 30 acres of 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 5 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,  tetrachloroethylene,
  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 Brookhurst subdivision.  The source  or sources  of this contamination is as
  yet unknown.

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

       KN Energy and Dowell Schlumberger—signed a Consent Agreement with EPA on
  December 15, 1987 in which they agreed to conduct a remedial  investigation/
  feasibility  study to determine the type  and extent  of contamination at the site
  and identify alternatives for remedial action.
