                                        SECTION I
                                     INTRODUCTION
Superfund was created by Congress in 1980 with
the   passage  of   the   Comprehensive
Environmental  Response,  Compensation, and
Liability Act of 1980 (CERCLA). On October 17,
1986,  the   Superfund   Amendments   and
Reauthorization Act of 1986 (SARA) was enacted.
SARA  reflected   EPA's   experience  in
administering the complex Superfund program
during its  first  six  years and  made several
important changes and additions to the program.
SARA stressed the importance  of permanent
remedies and innovative treatment technologies
in cleaning up hazardous waste  sites; required
Superfund actions to consider the standards and
requirements found in other  Federal and State
environmental laws and regulations; provided
new  enforcement  authorities and settlement
tools; increased State involvement in every phase
of the Superfund program; increased the focus
on human health problems posed by hazardous
waste  sites;  and encouraged greater  citizen
participation in making decisions on how sites
should be cleaned up.

The Superfund remedial program has modified
its approach to site  cleanups  to  reflect the
mandates in CERCLA, as  amended by SARA.
For example, Section 121 of CERCLA mandates
the  selection  of a  remedial action  that  is
protective of human health and the environment,
complies  with  applicable or  relevant  and
appropriate  Federal  and  State  requirements
(ARARs), is cost-effective, and utilizes permanent
solutions and alternative treatment technologies
or  resource  recovery  technologies   to  the
maximum extent practicable.    In addition,
CERCLA includes a preference for remedies that
employ  treatment   that  permanently  and
significantly reduces the volume, toxicity, or
mobility of  hazardous wastes as a principal
element.

The Records of Decision (RODs) highlighted in
this annual report, document compliance with
SARA mandates for the remedial program in FY
1991.  Each ROD discusses the remedy decision
for a site or operable unit,  certifies  that the
remedy selection process has  followed the
requirements of CERCLA  and  the  National
Contingency Plan (NCP), discusses the major
technical  components  of  the  remedy,  and
provides the public with a consolidated source of
information about the site.  Once the Regional
Administrator or the Assistant Administrator of
the Office of  Solid Waste and Emergency
Response signs the ROD, it is made available for
information  purposes  and  placed   in   the
administrative record for the site. Nine hundred
forty-five (945) RODs have been signed since the
Superfund program began (see Exhibit 7).

FY 1991 RODs

One hundred   eighty-three (183) RODs  and
thirteen  (13)  ROD  Amendments,  including
Fund-lead,  Enforcement,  and Federal Facility
RODs were signed during FY 1991. The data in
this annual report are based on these 196 RODs
and ROD Amendments; for clarity,  these  are
collectively referred to as RODs throughout the
remainder of the report.  One hundred forty-one
(141) of the 196 RODs addressed source control
remediation, and 46 RODs  addressed ground-
water-only remediation.  The remaining 9 RODs
were no action/no further action remedies.  Of
the total 141 source control RODs, 114 addressed
a final source control remedy, and 27 addressed
an interim source control  remedy. Eighty-five
(85) of the 141 source control RODs selected both
source  control  and ground  water remediation
components.

In keeping with CERCLA Section 121 and  the
NCP program expectations to treat highly toxic,
highly  mobile  wastes and  contain low level
wastes or large volumes  of waste, 'treatment
technologies' were used for 99 (70%) of the  141
source   control  remedies   (see   Exhibit 3A).
'Treatment  technologies'  are  those  selected
source  control technologies listed at the top of
Exhibit 2, as opposed to other types of treatment.
In a further breakdown, source control treatment
technologies plus the other  types of treatment,
were selected for 77 (68%) of the  114 'final'
source  control  RODs  (see Exhibit  3B).   A
historical overview of the  increase in  treatment

-------
selected for source control and  'final' source
control RODs since 1982, is shown in Exhibits 3A
through 3C.   Exhibits 3A and  3C show the
percentages  of   Superfund  source  control
remedies  which  have  chosen  all types  of
treatment,  while   Exhibit  3B   shows   the
percentages of 'final'  source control remedies
since 1987 that have used treatment technologies.
It was not until after SARA, in 1986, that more
data  on  the  'final'  source control remedies
became available for comparison.

Exhibits

Exhibits 1 through 13 summarize various data
from  the 196  FY 1991 RODs, and similar data
comparisons  for  all  RODs  since FY  1982.
Exhibit 1  provides an overview of the  types of
remedial action selected for all FY  1991 RODs.
Exhibit 1A provides the same overview for all
RODs FY 1987 - FY 1991.

Exhibit 2 provides a quantitative summary of
remedial  action components by the number of
occurrences in RODs.   Occurrences means the
count of one or more technologies, which may be
associated with a remedial action described in
the ROD.  For example, a ground  water remedy
may consist of air stripping, aeration, and carbon
adsorption, as  part of a treatment train, which
would consist of three occurrences.  This exhibit
demonstrates  that  occurrences of  the use of
treatment technologies (146) for the 141 source
control remedies exceeded that of containment
only remedy occurrences (35) by a factor of four.
Of  the  146  occurrences  of  source  control
treatment technologies, immobilization  (35) and
in-situ vacuum/vapor extraction treatment (34)
were  selected most frequently,  followed by
thermal destruction/incineration (24).

Exhibit 3  compares  the  number of  FY  1991
source control RODs employing 'containment' as
a primary component of the remedy, with RODs
employing 'treatment' as a principal  component.
Exhibit 3A shows  the percent  of all source
control RODs that used some type of treatment,
as a percent of all the source control RODs for
each year.  For example, there were 141 source
control RODs  in FY  1991, and  of those  141
RODs, 99  (70%)  used  'treatment  technologies'.
The remainder of the source control RODs in
FY 1991 used containment or other actions for
the source control remedy. Exhibit 3B shows the
percent  of 'final' source control  RODs, which
employed some type of treatment.  Exhibit 3B
shows that  in FY 1991, 77 (68%) of the 'final'
source  control RODs  (114)  used  treatment
remedies.  The remainder  (37)  of  the 'final'
source control RODs in FY 1991 used other types
of remedies.  Exhibit 3C  shows out of all the
RODs each year, what percent of remedies  have
used treatment technologies for source control,
versus the percent utilizing  containment  only
and  other  actions.   Exhibits  3 through 3C
indicate that the use of treatment for Superfund
remedy  selection has increased  and remained
about constant for the past four years between
FY 1988 and FY 1991.

Exhibit 4 illustrates the occurrences of treatment
technologies in FY 1991  source control remedies
by treatment technology.  Separation/recovery
was  the main treatment  technology category,
followed  by  destruction/detoxification
technologies.  Exhibit 4A  shows the same data
for all occurrences of technologies since FY 1982.

Exhibit 5 shows the total  number of treatment
occurrences (270) for ground water remedies in
FY 1991 RODs. The majority of ground water
treatment occurrences were physical/chemical
treatment technologies  (83%),  including air
stripping, carbon adsorption, and precipitation.
Biological treatment  was employed in 2% of the
treatments, and the  remaining 15% of ground
water remedies  used  other technologies  to
restore ground water to its beneficial uses within
a reasonable timeframe.

An index of  site remedies  for FY  1991  is
provided in Exhibit 6, which  contains RODs
grouped by  the specific type of source control
and/or non-source control remedy selected. To
assist in understanding  the  technology  data
presented in Exhibits 1 through 6, a description
of each source  control  and  ground water
treatment occurrence is provided in Section V of
this Volume.

Historical Overview FY 1982-1991

The passage of SARA strengthened and extended
the Superfund program while maintaining the
overall framework for implementation.  New
requirements under CERCLA, as amended by
SARA, were intended to ensure protective clean-
up standards, permanent remedies, and the use
of alternative technologies where applicable.  A
historical overview of FY 1982 - FY 1991 RODs is
provided in  Exhibits 7 through 11 to show
annual progress in achieving  these statutory
mandates.

Exhibit 7 depicts the number of RODs signed per
fiscal year.  Exhibit 8 is a quantitative overview
of the  occurrences  and  type of  treatment
technologies which have been selected in the 99
source control  treatment  technology   RODs.
Exhibits 10 and 11 provides a list of individual
sites where these treatment technologies were
selected.

Comparative data on the number of RODs and
number of occurrences of treatment technologies
and 'innovative' technologies selected for source
control RODs (FY 1987 - FY 1991) are presented
in Exhibit 9. These data demonstrate that there
has been: (1) an increase in the percentage of
RODs selecting treatment as a principal  remedy
for source  control, and  (2) an  increase in the
percentage of innovative treatment technologies
selected.

Exhibits  12  and 13  illustrate and  list  the
information for  FY 1991 treatment train RODs,
i.e., RODs which employ a sequence of treatment
technologies to address a single  medium or
constituent. Exhibit 14 provides a comparison of
FY 1982 - FY 1991 ROD data on remedial action
costs.

                       DOVER MUNICIPAL LANDFILL, NH
                                September 10,1991
SITEHISTORY/DESCRIPTION:
The 55-acre Dover Municipal Landfill site is an
inactive landfill in Dover, Strafford County, New
Hampshire.   Land use in  the  area is rural-
residential and recreational.  The site overlies
both an upper  and a lower aquifer  that are
separated  by impermeable clay.   Significant
nearby surface water bodies include the Bellamy
reservoir located 2,000  feet south  of  the  site,
which  supplies  drinking  water  for  local
municipalities; the Calderwood well,  which
supplies drinking water for the  City of Dover,
and is located approximately one-half mile north
of the landfill; and the Cocheco River, which
runs approximately 500 feet east of the landfill.
A portion of the site lies within the  100-year
floodplain  of the  Cocheco River, and  four
wetland systems are in the  vicinity of the site.
From  1960  until  1979,  the landfill accepted
municipal  and  industrial  wastes  including
drummed materials and liquid wastes. Landfill
disposal practices  included  trenching, burning,
and fill and cover methods. Between 1980 and
1982, the facility was capped and closed, and a
drainage channel  was  excavated  around the
landfill to intercept leachate.   In  1981, VOC
contamination was found in private residential
wells  screened in the upper  aquifer  in the
vicinity of  the landfill.    Further  analyses
identified   two   contaminant   plumes,  one
migrating to the south and the other moving to
the east.   This ROD  addresses both  source
control and management of  migration of
contaminated ground water, as a final remedy.
The primary contaminants of concern affecting
the soil, sediment, sludge, debris,  and ground
water  are VOCs including benzene, PCE, TCE,
toluene, and vinyl chloride; other organics; and
metals including arsenic.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating  and  consolidating approximately
300 cubic yards of sediment from the drainage
channel, and  depositing the material  into the
landfill  prior  to  capping;  recontouring  and
capping the landfill with a multi-media cap with
a  passive venting system  for methane  gas;
pumping and onsite treatment of the southern
plume ground water and leachate using aeration
for VOC removal, carbon adsorption to remove
other organics, and flocculation, coagulation, and
precipitation,  followed by  discharge  of  the
treated water onsite to surface water or offsite to
the Dover POTW; disposing of residual sludge
offsite;  constructing  a  clean  ground  water
diversion system upgradient of the site; natural
attenuation of the eastern plume ground water;
constructing a  surface  water  run-on/run-off
diversion system; conducting long-term ground
water  monitoring;   and  implementing
institutional controls including deed and ground
water use restrictions.   If it is determined  that
the selected ground water treatment remedy for
the  southern  plume  is   not  effective,  a
contingency remedy that utilizes precipitation
and air stripping will be  implemented.  The
estimated present worth cost for  this  remedial
action is $24,155,700, which includes an annual
O&M cost of $157,680 for 10 years and an annual
cost for ground water monitoring of $721,600 for
30 years.

PERFORMANCE STANDARDS OR GOALS:

Sediment in areas where arsenic levels are above
50 mg/kg will be excavated and consolidated
under the landfill cap.  Ground water interim

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 850-acre Groveland Wells site is a municipal
well field in Groveland, Massachusetts.   Land
use in the  area is residential, industrial, and
commercial. The site is bounded to the north by
the Merrimack River; to  the  west by the
Haverhill Municipal Landfill, which is another
Superfund  site; and to the  south and east by
mixed land  use areas. The site is underlain by a
surfical unconsolidated aquifer, which is a source
of ground water for the well field, and a deeper
bedrock aquifer.  Both a current and  a former
municipal water supply well are located within
the site boundaries. Johnson Creek, including its
associated wetlands, flows across the  site, and
portions of the site lie  within  the  100-year
floodplain  of  the  Merrimack  River.   In  1979,
elevated levels of  TCE were discovered  in the
onsite  water  supply  wells, resulting in the
closure of  the wells, development of  alternate
water supplies, and investigations by EPA. An
initial remedial measure (IRM) by EPA in 1985
provided an alternate water supply by installing
a carbon adsorption unit on one of the onsite
water  supply  wells.    EPA  investigations
'dentified three likely sources of contamination:
the A.W. Chesterton Company, currently being
remediated  under  RCRA corrective action and
closure  activities;  the  Haverhill  Municipal
Landfill, which has been addressed as a separate
CERCLA action; and the Valley Manufactured
Products Company (Valley), a screw  machine
products manufacturer and finisher. From 1963
to 1974, Valley operations involved the release of
UP to 3,000 gallons of waste oil and  solvents,
Deluding TCE, to  the  soil either from a major
Ť*k of 500-700 gallons of TCE that escaped from
an underground storage tank, other onsite spills
Or leaks into  the subsurface disposal  systems,
and the use of waste oil containing TCE as a
defoliant. A 1988 ROD provided for removal of
source contamination from the Valley  property
using vacuum extraction, and installation of a
ground   water   recovery,  treatment,   and
reinjection system to treat VOC-contaminated
ground water beneath the property.  The State
also required Valley to install a ground water
pump and treatment system using air stripping
to intercept the plume at Mill Pond, an onsite
man-made water body.  This ROD  addresses
management of migration of contamination in
the surfical and bedrock aquifers extending from
the valley site, as a final remedy.  The primary
contaminants of concern affecting the  ground
water are VOCs including benzene, PCE, TCE,
and  toluene;  and metals  including  arsenic,
chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
pumping and treatment of ground water using
an  inorganics removal  system consisting of
equalization/aeration, flocculation, coagulation,
sedimentation, and filtration; disposing of the
resulting sludge offsite; further treating ground
water using ultraviolet light and oxidation to
remove  VOCs; discharging the treated water
onsite to Johnson  Creek;  monitoring  ground
water,  surface water,  and  sediment;   and
implementing  institutional controls  including
deed and ground  water use restrictions.   The
estimated present worth cost for this remedial
action is  $8,900,000, which includes an annual
O&M cost of $333,000 for 30 years.

PERFORMANCE STANDARDS OR  GOALS:

Interim ground water clean-up levels  are based
on  the  more  stringent  of  Federal  MCLs or
non-zero MCLGs, or  State MCLs. Chemical-
specific  ground water  goals include benzene
5 ug/1 (MCL), PCE 5 ug/1  (MCL), TCE 5 ug/1
(MCL), toluene 1 mg/1 (MCL), arsenic 50 ug/1
(MCL), and  chromium 50 ug/1 (MCL).   The
clean-up level for lead, 15 ug/1, is based on EPA
Superfund Policy.  When all interim levels are

                                     June 27,1991
SITE HISTORY/DESCRIPTION:

The  552-acre Iron Horse Park site is an active
industrial complex and railyard with a  long
history  of  activities  that  have  resulted  in
contamination of soil, ground water, and surface
water in North Billerica, Massachusetts.  The site
includes  open  storage areas,  landfills,  and
lagoons.  This ROD addresses the onsite 60-acre
landfill, known as the Shaffer Landfill, that was
used for disposal of residential and commercial
solid waste from 1946 until its closure  in 1986.
The  Shaffer Landfill is surrounded by wetlands
and  lies  within  the  100-year  floodplain  of
Middlesex Canal  and  Content  Brook, which
border  the   site   to   the  east  and  south,
respectively.  Land use outside the surrounding
wetlands areas is predominantly industrial and
residential. As a result of State investigations in
1980, EPA identified onsite contamination in
ground water, surface water, and soil;  and the
presence  of asbestos.  In 1984, EPA, under its
removal authority, covered  an onsite asbestos-
contaminated  landfill.     After   further
investigation, EPA divided the site into operable
units (OUs)  to facilitate remediation.  A  1988
ROD addressed the B&M Lagoon  site as OU1,
which includes the contaminated waste lagoons
located on another portion of this site.   This
ROD addresses OU2, final  remediation of the
Shaffer Landfill, including leachate and ground
water. A future ROD will address surface water
contamination as  part of OU3.   The primary
contaminants of concern affecting the landfill
materials, ground  water, and air are VOCs
including benzene, TCE, toluene, and xylenes;
other organics  including  PAHs;  and metals
including arsenic and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
reconstructing the 60-acre existing landfill cap;
maintaining   the  cap,  the   existing  surface
drainage system, and  the  existing landfill  gas
collection/flare system; constructing, operating,
and  maintaining a leachate collection system;
treating  and  disposing of  leachate offsite;
monitoring ground water, surface water, and the
gas collection/flare system; and implementing
institutional controls including deed and ground
water use restrictions.  The estimated present
worth cost for this remedial action is $12,553,524,
which includes a present worth O&M cost of
$3,541,426 for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Interim chemical-specific ground water clean-up
goals are based on SDWA MCLs, and include
arsenic 50 ug/1 (MCL), benzene 5 ug/1 (MCL),
and TCE 5 ug/1 (MCL).

INSTITUTIONAL CONTROLS:

Deed and ground water use restrictions will be
imposed on the property to prevent  the use of
the aquifer as a drinking water source and to
ensure site activities will not compromise  the
integrity of the landfill cap.

                                    March  29,  1991
SITE HISTORY/DESCRIPTION:

The  50-acre  Mottolo  Pig Farm  site  is in
Raymond, New Hampshire. Surrounding land
is primarily rural residential and undeveloped.
The  site  includes a wooded area, an inactive
piggery area comprised of several structures, a
building drum disposal area, and wetlands. An
onsite  brook  (Brook A)  originating  in  the
wetlands discharges into the Exeter River. Prior
to 1975, a piggery operation was located onsite.
From 1975 to  1979,  the owner disposed of 1,600
drums and pails containing hazardous wastes in
a disposal area north of the piggery building,
and subsequently filled in the area. In 1979, the
State identified onsite buried  drums some of
which were crushed and leaking. Consequently
in 1980, EPA began excavation and staging of
these drums.  From 1981 to 1982, EPA removed
and   characterized   drummed  waste,  then
transported the  waste offsite  along with 160
cubic yards of contaminated soil, drum parts,
and  plastic sheeting.   The  area  was  then
regraded and seeded.  This  ROD addresses
contaminated  onsite  soil, debris,  and  the
associated ground water plume.  The primary
contaminants of concern affecting the soil, debris,
and  ground water are VOCs including TCE,
toluene, vinyl chloride, and xylenes; and metals
including arsenic.

1ELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
installing a ground  water interceptor trench
upgradient of the former drum disposal area to
reduce migration of contaminants and facilitate
treatment of contaminated soil; capping the
drum disposal  and southern boundary  areas
with temporary waterproof  caps  to  improve
treatment  efficiency;  treating approximately
3,4004,000 cubic yards of VOC-contaminated soil
at these areas using in-situ vacuum extraction
and  activated  carbon to  control  off-gases,
followed by onsite or offsite carbon regeneration
and disposal; allowing the contaminated ground
water plume  to be restored  through  natural
attenuation;  monitoring ground  water  and
surface water;  and implementing  institutional
controls including deed and ground water use
restrictions, and site access restrictions  such as
fencing. The present worth cost for this remedial
action  is $690,000, which  includes a  present
worth O&M cost of $280,000.

PERFORMANCE STANDARDS OR GOALS:

Soil clean-up levels were established to protect
ground water from soil leachate. Ground water
interim clean-up levels  were  based on  Federal
SDWA MCLs  and  MCLGs,  or State Health
Advisory Levels. The estimated time frames for
the restoration  of  the  overburdened  ground
water affected by the drum disposal area soil
and the bedrock ground water affected by the
southern boundary soil to acceptable levels by
natural attenuation are 6 years and  2 years,
respectively.

INSTITUTIONAL CONTROLS:

Deed and ground water use restrictions will be
implemented onsite.

SITE HISTORY/DESCRIPTION:

The  35-acre Nyanza Chemical site is a former
dye   manufacturing   facility   in   Ashland,
Middlesex   County,   Massachusetts.    Land
adjacent  to the  site  is  used  for  industrial
residential,   commercial,  and  recreational
purposes. Wetlands are located to the north and
east; woodlands lie to  the south, southeast, and
west; and the Sudbury River is 700 feet north of
the site.   The site overlies an unconsolidated
glacial aquifer, which  has been affected by site
activities. The study area for this ground water
operable  unit is larger  than the site and consists
of up  to 395 acres.   From 1917 to 1978, the
property  was occupied  by several companies
involved  in manufacturing  textile  dyes, dye
intermediates, inorganic  collodial  solids and
acrylic polymers.  Starting in 1917, several types
of wastes were disposed of in various onsite
locations  including Megunko Hill, an unsecured
landfill/disposal area in the southern portion of
the site,  and wetlands areas to the east and
northwest. Wastes included process wastewater,
chemical  sludge, solid process wastes in drums,
solvent recovery distillation residue in drums,
off-specification  products,  and  un-recyclable
process   chemicals   including   phenol,
nitrobenzene, and mercuric sulfate.  The dye
waste stream and wastewater were discharged to
an onsite concrete  "vault" or settling  basin
adjacent  to the main processing building.  The
liquid occasionally overflowed through a  pipe
into the wetlands and  to  surface water. In the
1960's  or 1970's, the vault was removed from
service, and subsequently was filled  in  with
sludge and covered over with fill.  In 1970,  a
State investigation linked the site to mercury
contamination in the nearby Sudbury River.  A
1985 ROD addressed soil and wetland excavation
at nine  localized  areas  of  contamination;
solidification of water-bearing excavated sludge,
sediment, and soil; and placement, capping, and
consolidation of those materials left in place on
Megunko Hill, as Operable Unit 1 (GUI).  In
addition, a diversion trench was constructed on
the side of Megunko Hill to divert surface water
flow, and lower the ground water table around
Megunko Hill.  In 1985,  the State  constructed
fencing along a road embankment, placed one
foot  of clean fill over an area to prevent direct
contact, and culverted surface water through a
neighboring property under an Interim Response
Measure. In 1987, under an EPA removal action,
655  tons  of soil  adjacent to  the  vault  were
removed, 309 tons were incinerated, and 356 tons
of soil were transported offsite to an approved
landfill. In 1988, EPA solidified onsite 2,000 tons
of sludge from the vault and  disposed of the
sludge at an offsite RCRA landfill facility. This
ROD addresses management of migration as
OU2,  and  constitutes an   interim  remedy
designed  to treat  the highest ground  water
contamination  and  to  collect  additional data
achieving cleanup objectives.   A  subsequent
ROD will address uncontrolled  wastewater
discharges to  the Sudbury  River   and  its
tributaries.   The  primary  contaminants  of
concern affecting the ground water are  VOCs
including benzene, PCE, TCE, and toluene; other
organics;   and  metals   including   arsenic,
chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected interim remedial action for this site
includes constructing  extraction wells at the
northern border of  the  site; constructing  a
ground   water  treatment  plant that  utilizes
precipitation and filtration to remove inorganics,
and ultraviolet oxidation or biological treatment
as well as carbon adsorption to remove organics,
pumping and treating ground water, with onsite
discharge of the treated water to surface water;
performing pump tests in the eastern portion of
the plume to  determine the need for future
ground  water remediation; installing additional
deep bedrock wells to fully define depth and
                                             87

                  SAVAGE MUNICIPAL WATER SUPPLY,  NH
                                September 27,1991
SITE HISTORY/DESCRIPTION:

The Savage Municipal Water  Supply  site is
located in Milford, New Hampshire. The site
and  surrounding  properties  encompass  the
Savage Municipal Well, four major industrial
facilities,  and two  fish hatcheries.  Land use
includes residential, agricultural, heavy and light
industrial, and commercial areas.  The site is
located within the 100-year floodplain of the
Souhegan River, which is the principal stream
flowing through the site.  From the 1940's to the
1980's, process  and  wastewaters  from  the
industrial facilities were released untreated to the
ground water or to the surface waters flowing
through the site.  In 1983, the State identified
concentrations of several VOCs that were above
drinking  water standards  in water from the
Savage Municipal Well and water drawn  from
the well supplying a nearby trailer park. At the
State's request, EPA conducted a removal action
in 1983.  This  included temporarily supplying
bottled water to affected residences in the trailer
park,  and  connecting  the residences  to the
existing municipal water supply system.  This
remedial  action  addresses potential risks  to
future use of the aquifer caused by ground water
contamination  at the site,  within a 6,000- by
2,500-foot contaminated ground water  plume.
This ground water plume was divided into two
zones: the concentrated plume, which contains
the highest concentrations of contaminants; and
the extended plume, which has the remainder of
the contaminated ground water.  The primary
contaminants of concern affecting  the ground
water  are VOCs including benzene, PCE, TCA,
and   TCE;   and  metals  including  arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
onsite   pumping   and   treatment  of   the
concentrated and extended plume areas using air
stripping and ultraviolet oxidation; discharging
the treated ground water onsite; use of natural
attenuation to aid in contaminated ground water
remediation  until  clean-up  levels   are  met;
implementing ground water, surface water, and
sediment  monitoring   programs  during
remediation;  and  implementing  institutional
controls including deed and ground water use
restrictions.  The estimated present worth cost
for this remedial action  is $15,500,000, which
includes an annual O&M cost of $1,400,000 for
30 years.

PERFORMANCE STANDARDS OR GOALS:

Interim  ground water  clean-up levels  for
carcinogenic compounds  have been  set at the
more stringent of MCLs, non-zero MCLGs, or an
excess cancer risk of 10~6- Clean-up levels for
non-carcinogenic compounds have been set at
the non-zero MCLG or  an HI*1. Ground water
clean-up levels include benzene 5  ug/1 (MCL),
PCE 5 ug/1 (MCL), TCE 5 ug/1 (MCL), arsenic
50 ug/1 (MCL), chromium 100 ug/1 (MCL), and
lead 15 ug/1 (action). Final protective clean-up
levels will be developed after interim levels have
been attained or the remedy is otherwise deemed
protective.

INSTITUTIONAL CONTROLS:

Deed and ground water use restrictions will be
implemented to restrict the use of contaminated
ground water.

                                 September  19,1991
SITE HISTORY/DESCRIPTION:

The 4.5-acre Silresim Chemical site is a former
chemical waste reclamation  facility in Lowell,
Massachusetts.    Land  use  in  the  area  is
predominantly industrial,  although residential
areas are located to the south, east, and northeast
with the closest residences approximately 300 to
500 feet from the site. The nearby residences
obtain  their drinking water  from a municipal
water  supply.   From 1971  to 1977,  Silresim
Chemical Corporation (SCO  used  the site for a
chemical waste reclamation facility. The facility's
primary  operations  included  recycling  and
reclaiming various chemicals and consolidating
waste for offsite disposal.  The facility handled
approximately 3 million gallons of waste per
year including halogenated solvents, oily wastes,
alcohols, metal sludge, and  plating and pesticide
wastes. From 1977 to 1978, SCC abandoned the
facility, leaving approximately 1 million gallons
of hazardous waste  onsite in  bulk tanks and
nearly   30,000  decaying   drums.     State
investigations revealed evidence of numerous
spills, leakage of drums, discharges to nearby
sewers, and run-off  to adjacent property.   A
number of EPA and State investigations revealed
contamination of soil and ground water.  From
1978 to 1982, the State  constructed a fence,
removed liquid waste in onsite drums and tanks,
and  constructed  berms  and  absorbent-filled
trenches. From 1983 to 1984, EPA removed all
onsite structures, extended the fence, and placed
a clay  cap over the  site.  This ROD addresses
both onsite and offsite soil and ground water
contamination.  The primary contaminants  of
concern affecting the  soil and ground water are
VOCs  including benzene, TCE, toluene,  and
xylenes; other organics including dioxin, PAHs,
PCBs, and phenols; and metals including arsenic,
chromium, and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
constructing   additional   perimeter   fencing;
placing a low-permeability temporary cover over
areas of contaminated offsite soil; extending and
repairing  the  existing  cap  as   required;
conducting in-situ vacuum/vapor  extraction of
approximately  137,000  cubic   yards   of
contaminated soil; excavating and stabilizing any
soil with residual contamination after treatment
with  vapor  extraction,  followed by  onsite
disposal; backfilling excavated areas with clean
fill; installing a RCRA Subtitle C cap over the
stabilized soil; pumping and pretreatment of
ground water using a phase separation tank to
separate non-aqueous phase liquids (NAPLs),
followed by   chemical addition,  flocculation,
precipitation,  and filtration to remove metals;
offsite disposal of NAPLs and residuals from the
metals removal process; treating residual ground
water using  air stripping of heated influent,
thermal oxidation,  and aqueous phase carbon
adsorption, followed by offsite discharge  of the
treated  ground water to the  municipal  sewer
system  or  onsite discharge  to  surface  water;
conducting long-term soil, surface water,  and
ground water monitoring; and implementing
institutional controls including deed, ground
water, and land use restrictions.  The estimated
present worth cost  for this remedial  action is
$22^00,000, which  includes  a  present  worth
O&M cost of $9,263,000.

                                 September 27,1991
SITE HISTORY/DESCRIPTION:

The Sullivan's Ledge site consists of a 12-acre
former quarry site/disposal area and 14.5 acres
of downgradient wetlands areas in New Bedford,
Bristol County, Massachusetts. Land use in the
area   is   predominantly  municipal.     The
downgradient portion of the site, which is the
focus of this ROD, includes two wetlands areas:
a 13-acre wooded wetland called Middle Marsh
bordering  the Unnamed Stream and a 1.5-acre
wetland area 400 feet upstream from Middle
Marsh  called the "adjacent  wetlands".   In
addition, the site includes portions of golf course
fairways,  and  associated   floodplains   and
watershed areas. The entire site lies within the
25- and 100-year floodplains of a tributary of the
Unnamed   Stream  to  the   south  and  the
Apponagansett Swamp to the north.  Prior to
1930,12 acres of the site were used as a granite
quarry.  From the 1930's to 1970% the City of
New Bedford acquired the property and used
the quarry pits and nearby areas were used for
disposal  of  hazardous  materials  including
electrical transformers and capacitors, fuel oil,
volatile liquids,  and other industrial wastes.
From 1988 to 1990, several EPA investigations
identified contamination by PCBs and PAHs in
surface and subsurface sediment, soil, and biota;
and VOCs and  inorganics in ground water.
Contamination  has  resulted  in   part  from
contaminated  sediment migrating from the
disposal area via the  Unnamed Stream and
deposition  in Middle  Marsh during stream
flooding.  A 1989 ROD for the first operable unit
(OU1) addressed source control of the disposal
area  and  the Unnamed Stream.   This  ROD
addresses  the Middle  Marsh  as  OU2.   The
primary contaminants of concern affecting the
soil,  sediment,  and  surface  water are VOCs
including  toluene;  other  organics  including
PAHs, PCBs, pesticides, and phenols; and metals
including lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and dewatering approximately 5,200
cubic yards of contaminated sediment and soil
from portions of Middle Marsh and the adjacent
wetlands; solidifying/stabilizing the excavated
materials as needed to comply with RCRA LDR
rules;  treating water extracted from excavated
materials using carbon adsorption, followed by
onsite discharge to the Unnamed Stream; onsite
disposal of the excavated materials beneath the
cap that will be constructed over portions of the
disposal area as part of OU1; restoring affected
wetlands; conducting long-term environmental
monitoring;  and  implementing institutional
controls to prevent future  residential use of
Middle Marsh and the adjacent wetlands. If the
disposal area  in OU1 has  already been capped
when  materials from OU2 are excavated and
ready for disposal, a contingency remedy will be
implemented. This contingency remedy includes
treating the  excavated  soil/sediment using
solvent extraction, and treating the extracted oil
containing PCBs and other organic chemicals
offsite using incineration; treating residual water
using carbon adsorption; disposing of the treated
sediment/soil  at  Middle  Marsh;  restoring
affected   wetlands;   conducting  long-term
environmental monitoring; and implementing
institutional controls to prevent future residential
use of Middle Marsh and the adjacent wetlands.
The estimated  present  worth  cost  for  this
remedial action is $2,800,000, which includes a
present  worth O&M cost of $164,000.   The
estimated present worth cost for the contingent
remedy  is  $7,780,000, which includes a present
worth O&M cost of $164,000.

PERFORMANCE STANDARDS OR GOALS:

Soil, sediment, and surface water clean-up goals
are based on an excess lifetime cancer risk of 10"4
to 10"6 and an HI=1. The sediment/soil clean-up
level for aquatic areas in Middle Marsh is the
interim mean sediment quality criterion of 20 ug
of total PCBs per gram of carbon (ug/Gc). This
will  result  in interstitial water concentrations
equal to or lower than the PCB ambient water
quality criteria of 0.014 ug/1.  The sediment/soil
clean-up level for non-aquatic areas in Middle
Marsh and for the adjacent wetland is total PCBs
15 mg/kg.   This will protect mammals from
chronic adverse effects from wetland/terrestial
exposure to contaminated sediment/soil.

INSTITUTIONAL CONTROLS:

Land  use   or  deed  restrictions  will  be
implemented to ensure that Middle Marsh and
the adjacent wetland  are limited to recreation
and conservation purposes.

SITE HISTORY/DESCRIPTION:

The  12.5-acre Union Chemical (UCC) site is an
inactive paint stripping solvent manufacturing
and  recycling facility in  Hope, Knox County,
Maine.  Land use in the area is residential, and
a  pond is  located  approximately  300  feet
northeast of the site. The site is bounded on the
east  and southeast by Quiggle  Brook,  which
flows southward for 5 miles before discharging
into Crawford Pond, a drinking water source. A
floodplain  and  a wetland area exist along
Quiggle Brook at the eastern edge of the site,
and another wetland has been identified to the
south.   Site operations, which began in 1967,
included formulating patented solvents for paint
stripping and coating.  These products were
manufactured and utilized  on the premises in
several onsite buildings.  Later operations also
included recycling of used stripping compounds
and  solvents  from other businesses on a small
scale until  1982, when a fluid-bed incinerator
was  acquired.   In 1979,  State  investigations
identified the presence of onsite  ground water
contamination.  Subsequent private studies in
1981 confirmed the presence of contaminated
ground  water in the area between the facilities
and  Quiggle  Brook.  The State issued several
violations to the owner between 1979 and 1984,
and eventually closed the plant in late 1984.  At
that time approximately 2,000 to 2,500 55-gallon
drums  and  30  liquid  storage  tanks were
identified onsite.   In 1984,  the State  and EPA
removed the 55-gallon drums and all but two of
the liquid storage tanks.  This ROD addresses
remediation of onsite soil, debris, sludge, ground
water, and facilities,  and provides for further
evaluation  of contaminated offsite soil.  The
primary contaminants of  concern affecting the
soil, debris, sludge, and  ground water, are VOCs
including PCE, TCE, toluene, and xylenes; other
organics  including  dioxin;  metals including
arsenic and lead; and other inorganics including
asbestos.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
decontaminating all onsite facilities including the
still building, production facilities, welding shop,
incinerator complex, concrete pads, the church,
all associated equipment, tanks,  above-ground
drums, and buried  pipes using  high pressure
steam  cleaning  or another  decontamination
technique; collecting and testing all wastewater
resulting   from  decontamination  operations,
draining  all contaminated water from sumps,
and  treating  onsite, if necessary,  using  UV
light/oxidation or equivalent another treatment
technology; crushing and treating all concrete
from the  warehouse pad, structures, floor, and
sumps by low temperature thermal desorption or
an equivalent desorption treatment;  backfilling
the treated concrete onsite, if  it meets LDR
standards, or removing it offsite for disposal at
a  RCRA facility;  removing and   containing
asbestos  from the still building, followed by
offsite  disposal;  treating  any  other  RCRA
hazardous wastes onsite including dioxin/Iead
scrubber ash, liquids, and sludge from the onsite
equipment  prior   to   offsite   disposal  by
solidification/stabilization;  demolishing  the
onsite  facilities  and  associated components;
sampling the debris and removing it offsite to
either a  RCRA  facility or permitted landfill
depending  on  testing   results;   excavating
approximately 10,500 cubic yards of soil from the
unsaturated and saturated  zones; treating the
contaminated soil onsite using low temperature
soil aeration or equivalent  thermal  desorption
technique; conducting treatability studies prior to
full-scale  treatment of contaminated soil; treating

                                      April 16,1991
 SITE HISTORY/DESCRIPTION:

 The 20-acre Western Sand & Gravel  site  is a
 former  liquid  waste  disposal  site  on  the
 boundary of Burrillville and North Smithfield,
 Rhode Island. Land use in the area is primarily
 semi-rural.  Tarklin Brook, which lies  within a
 wetland immediately to the west of the disposal
 area, discharges to a reservoir north of the  site.
 Residential areas  to the west and north of the
 site have private wells and use treated ground
 water as a source of drinking water. From 1975
 to 1979, approximately 12 acres of the site were
 used for the disposal of liquid wastes including
 hazardous substances and sewage. These wastes
 were dumped into 12 unlined lagoons and pits,
 and subsequently infiltrated through the porous
 soil and into the ground water. As a result  of a
 fire in one of the pits  in 1977,  local officials
 ordered the owner to remove chemicals from the
 site. After the owner failed to comply, a Cease
 and Desist Order was issued in 1979, and wastes
 were no longer accepted. In 1980 at the request
 of the State, EPA removed approximately 60,000
 gallons of VOC-contaminated liquid wastes from
 the lagoons. In 1982, the State began a ground
 water recirculation system to control the spread
 of contaminants in the ground water. Remedial
 activities for the  site  have been divided  into
 three operable units (OUs), addressed by three
 RODs. A 1984 ROD provided for installation of
 water  filters   in  affected   residences,   and
 subsequent provision for a permanent alternate
 water supply (OU1).  A 1985 ROD addressed
OU2, which  provided site  closure activities,
including capping contaminated soil areas with
a RCRA-approved  cap, phaseout of the ground
water recirculation system  with  removal  and
offsite  disposal of the associated  equipment,
evaluation  of alternatives  for ground  water
treatment, ground water monitoring, and
implementing site access restrictions such as
fencing.   This ROD addresses contaminated
ground water, which discharges into  Tarklin
Brook and the reservoir as OUS.  The primary
contaminants  of concern affecting the  ground
water are VOCs including benzene, PCE, TCE,
toluene,  vinyl chloride,  and  xylenes;  other
organics;   and   metals   including   arsenic,
chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
natural   attenuation   of   ground  water;
implementing a site monitoring  program for
sediment, ground water, and surface water; and
implementing institutional  controls to  restrict
consumption of ground water. A comparison of
current and historical data indicates that the
magnitude and extent  of  contamination has
decreased significantly  and  will continue to
decrease with  time as the integrity of the cap is
maintained.   Ground   water  is  expected to
achieve interim clean-up levels within 24  to 28
years. However, if this cleanup is proceeding at
an unacceptable rate, active restoration including
pumping  and treatment  by  sedimentation,
filtration, air stripping, and carbon adsorption,
followed by onsite discharge to Tarklin Brook
will be implemented as  a contingency remedy.
There  are  three  additional  scenarios   that
individually  may trigger  active  restoration.
These include: determining that Tarklin Brook is
endangered,   that   a   threat   exists   from
contamination  of   the  bedrock,   or   that
institutional controls cannot  be implemented
effectively. The estimated present worth  cost for
this remedial action is $1,123,952 ($4,039,227 with
active restoration), which  includes  an  annual
O&M cost of $1,041,452  ($2,990,151 with active
restoration) for 24 to 28 years.

PERFORMANCE STANDARDS OR GOALS:

Interim ground water clean-up goals are based
on  SDWA  MCLs  and MCLGs, a  10'6 excess
cancer risk level  and an  HI=1,  or practical
quantification limits.   Once  all ARAR-based
interim levels have been achieved, a risk analysis
will be performed to develop a cumulative risk
assessment.  The cumulative risk  of residual
levels must attain a 10"4  to 10"6 risk range for
carcinogens and an HI=1 for non-carcinogens
before these levels will be considered as the final
clean-up levels for any action. Chemical-specific
interim goals for ground water include benzene
5 ug/l (MCL), PCE 5  ug/1 (MCL), TCE 5 ug/1
(MCL), toluene 1 mg/1 (MCL), vinyl chloride
2 ug/1 (MCL), xylenes 10 mg/1 (PMCL), and
lead 5 ug/1 (PMCL).

INSTITUTIONAL CONTROLS:

Institutional   controls including  regulatory
restrictions, acquisition of affected properties or
ground water rights, and other.restrictions on
property transactions  may be implemented, as
needed, to reduce the risk to public health from
consumption of ground water.

                                     June 28,1991
SITE HISTORY/DESCRIPTION:

The 4-acre A.O. Polymer site is an active resin
manufacturer in Sparta,  Sussex County, New
Jersey.  Land use in the area is semi-rural, and
the facility is surrounded by wetlands. The A.O.
Polymer site is one-half mile from Sparta High
School which has an onsite well, and 500 feet
southeast of the Wallkill River, a ground water
discharge area.  The ground water in the area is
a current or potential source of drinking water.
From  the early  1960's  to   1978,  Mohawk
Industries operated as a resin production facility
and  also  reclaimed  electronic   component
cleaning fluids.   In  1978, the A.O. Polymer
Corporation purchased the site, and onsite resin
manufacturing operations continued  to utilize
the  same  storage  vessels  and  laboratories
previously owned by Mohawk Industries. State
investigations   in   1978  identified   VOC
contamination in local  drinking water,  and  in
1979 the affected residences were connected  to
the  public  water  supply.     Further,  State
investigations in 1978 identified improper waste
handling  and   storage   practices  including
disposal of liquid wastes into  unlined lagoons;
improper  storage  of  over 800 deteriorating
drums; and buried, crushed, and open  drums
containing VOCs and organic compounds.   In
1980 and 1981, the State excavated and removed
120 cubic  yards of crushed drums and  debris,
1,700 cubic yards of associated contaminated soil,
and  1,150 surface  drums.    In  1982,  State
investigations confirmed  that these disposal
practices had resulted in the contamination  of
potable ground water.  This ROD addresses soil
contamination in the former waste lagoon area
and the contaminated ground water plume, and
provides a final remedy for  the  site.   The
primary contaminants  of concern affecting the
soil and ground  water  are  VOCs including
benzene, TCE, toluene,  and xylenes; and other
organics including PAHs, PCBs, pesticides, and
phenols.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating contaminated soil onsite using vapor
extraction,  with control of  off-gas emissions
using  activated  carbon;  treating  minimal
amounts of liquid condensate with an onsite
ground  water treatment unit, or disposing of
liquid condensate offsite along with the spent
carbon; onsite pumping and treatment of ground
water using activated sludge in conjunction with
a powdered activated carbon treatment, followed
by filtration and a carbon polishing treatment;
reinjecting the treated ground water onsite with
a contingency for onsite discharge to surface
water, if necessary;  and disposing  of residual
sludge offsite.   An  ARAR  waiver  may be
necessary if onsite discharge standards to surface
water cannot be met.  The estimated present
worth cost for this remedial action is $4,577,000,
which includes an annual O&M cost of $218,000
for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Soil clean-up levels are based on State soil action
levels including total VOCs 1 mg/kg and total
organics  10 mg/kg.  Ground water will be
remediated to meet the more restrictive of State
or Federal MCLs.

SITE HISTORY/DESCRIPTION:

The 3.2-acre Applied Environmental Services site
is a former petroleum,  gasoline, and solvent
chemical facility in Glenwood Landing, Nassau
County, New York. The site is surrounded by
industrial,  commercial,   and   residential
properties. A tidal wetlands area of Hempstead
Harbor is located  to the west of the site. From
1939  to  1972, Texaco  Oil  Company  and,
subsequently, Phillips Petroleum used the site
for bulk  storage of petroleum products. From
1974 to 1980, Mattiace Petrochemical  Company
leased  part of the property,  and stored  and
distributed chemical solvents onsite. Numerous
spills  and  releases   have  occurred onsite,
including a tank  truck  spill  in  1978, which
released 3,000 gallons of toluene that soaked into
the sandy soil and spilled into  the adjacent
harbor.  From  1980  to  1984,  a  new tenant,
Applied   Environmental  Services,   blended
various chemical  waste  materials onsite  and
operated a hazardous waste storage  facility at
the site.  EPA and State  investigations in 1984
identified VOCs, metals, and organics in soil,
sediment, ground  water,  surface water, and air.
Consequently, in 1984, the current site owner,
Shore Realty, was  required  to remove 255 of the
410 drums containing hazardous waste that were
stored  on the  property.   In 1986 due to the
imminent danger  posed  by the site, the State
removed  approximately  700,000  gallons  of
hazardous  waste   including PCBs  from  the
facility. This ROD addresses contamination of
soil, ground water, sediment, surface water, and
air as a final remedy. The primary contaminants
of concern affecting the soil, sediment, ground
water, surface water, and air are VOCs including
TCE,  toluene, and  xylenes;  other   organics
including PCBs and  PAHs; metals  including
arsenic, chromium, and lead; and oils.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating contaminated soil using in-situ vacuum
extraction; onsite  pumping and  treatment of
contaminated ground  water using air stripping,
followed by reinjecting the treated ground water
along with nutrients and a chemical source of
oxygen to promote in-situ aerobic biodegradation
of contaminants  in  ground water and soil;
treating  air  emissions  from  the  vacuum
extraction and air stripping processes by catalytic
oxidation prior to release to the atmosphere; and
monitoring soil, sediment, ground water, surface
water, and air. The estimated present worth cost
for this remedial  action is $4,507,000, which
includes an annual O&M cost  of $970,000 for
4 years.

PERFORMANCE  STANDARDS OR GOALS:

Soil  clean-up goals are based on risk-based
criteria. Ground water clean-up goals are based
on State standards. Chemical-specific goals for
ground water include arsenic 25 ug/1, chromium
50 ug/1,  lead 25  ug/1, TCE 5 ug/1, toluene
5 ug/1, and  xylenes  15 ug/1.   For  all other
media, clean-up goals are based on applicable
standards for sediment, surface water, and air.

                                  September 27,1991
 SITE HISTORY/DESCRIPTION:

 The Asbestos Dump site is composed of four
 asbestos disposal areas in Meyersville, Passaic
 Township, New Jersey. This ROD addresses two
 of the four properties: the 30-acre New Vernon
 Road site and the 12-acre White Bridge Road
 site. These properties are bordered by the Great
 Swamp National Wildlife Refuge, and tracts of
 wooded and wetland areas.  Land use in the
 area  is primarily recreational  and residential.
 From 1968 to 1971, asbestos- containing material
 generated by the National  Gypsum Company
 was disposed of on the  New Vernon  Road
 property in a large depression and in other areas
 of the property.  From  1970 to 1975, asbestos
 material was disposed of on the White Bridge
 Road property in what  is now a horse-riding
 track and in other property areas.  In a 1990
 investigation,  EPA  identified  high  levels  of
 asbestos contamination in soil at both properties.
 Based on this investigation, the Agency for Toxic
 Substances and Disease Registry (ATSDR) issued
 a Public Health Advisory, and EPA conducted
 an immediate removal action at both sites, which
 included air and soil sampling for  asbestos,
 covering areas of visible asbestos contamination
 with  geotextile   fabric,   removing   any
 asbestos-containing  material  located  on  the
 ground  surface  for off site  disposal,  and
 restricting site access. A 1988 ROD addressed
 another site  property, the  Millington site,  as
 Operable  Unit 1  (OU1),   and provided  for
 constructing   slope   protection/stabilization
 measures and surface water diversion channels
 along and on top of the asbestos mound and
 installing security fences  and a soil cover.  This
 ROD addresses the asbestos-contaminated soil on
both the New Vernon Road and White Bridge
 Road properties, as OU2.  A subsequent ROD
 will address the fourth property, the Dietzman
Tract, as OU3,   The primary  contaminant  of
concern  affecting  the   soil is  asbestos,  an
inorganic.
 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 treating approximately 37,000 cubic  yards of
 asbestos-contaminated  soil   using   in-situ
 solidification/stabilization  and  covering  the
 solidified   material   with  6  inches  of  soil;
 conducting  confirmatory  sampling  of  soil,
 sediment,  ground  water,  and surface  water;
 implementing an air monitoring program; and
 implementing   institutional   controls.    The
 estimated  present worth cost  for this remedial
 action is $5,700,000, which includes an  annual
 O&M cost of $43,400.
 PERFORMANCE STANDARDS OR GOALS:

 The chemical-specific clean-up level for soil at
 both  sites  is  the  Transmission  Electron
 Microscopy (TEM) detection limit of 0.5 percent
 asbestos.
 INSTITUTIONAL CONTROLS:

 Institutional controls will  be  implemented  to
 restrict future surface and  subsurface activities
 which could affect the integrity of the  treated
 waste.

                                    March 29,1991
 SITE HISTORY/DESCRIPTION:

 The C&J  Disposal site is a former industrial
 waste disposal area in  the Town of Eaton,
 Madison County, New York.  Land use in the
 area is rural and  residential. Surface drainage
 flows toward a small pond located in a wetland
 area  100  feet  from the  disposal  area,  and
 ultimately drains into Woodman Pond.  Located
 3,000 feet to the  south of the  site,  Woodman
 Pond serves as a backup drinking water source
 for the nearby Village of Hamilton.  Currently,
 12 area residences use ground water as a source
 of  drinking water.   In  1976,  C&J  Leasing
 dumped paint sludge, liquid industrial wastes,
 and 75  to  100 drums into an  onsite disposal
 trench.  The trench was subsequently covered
 with  fill, burying the wastes and drums.   In
 1989, C&J Leasing conducted an unauthorized
 site excavation, which left two  large holes and
 three stockpiles of soil and waste material in the
 trench, as well as scattered crushed drums, cans,
 and plastic scrap material.  It  is believed that
 many buried drums were removed offsite during
 this excavation.    EPA  believes that onsite
 contaminants are primarily adsorbed or bound in
 the 1,250 cubic yards of waste material and soil
 and are not presently migrating into the ground
 water. This ROD addresses onsite contaminated
 soil and debris, and provides a final remedy for
 the site. The primary contaminants of concern
 affecting the soil and debris are VOCs including
benzene, toluene, TCE,  and  xylenes; other
organics including  PAHs and phenols;  and
 metals including lead.

 SELECTED REMEDIAL ACTION;
The selected remedial action for this site includes
dewatering the trench and  treating the water
before   recharge,  if   necessary;  excavating
approximately 1,250 cubic yards of contaminated
soil  and  debris  from  the  disposal  trench,
followed  by  offsite  treatment  or  disposal;
transporting drummed wastes generated during
the field investigation to an offsite RCRA facility
for treatment and/or disposal; backfilling the
trench; revegetating  the site; and  monitoring
ground water for one year. If all or a portion of
the  soil  and  debris is  classified  as  RCRA
hazardous wastes and require incineration to
meet land disposal restriction (LDR) regulations,
and  the wastes are managed prior  to May 8,
1992, the soil and debris  will be disposed of
offsite without treatment under a  National
Capacity Variance.    If  the wastes  require
treatment  other than incineration under  LDR
regulations,  the  necessary treatment will be
conducted offsite under a Treatability Variance.
That portion of the soil and debris not classified
as a RCRA hazardous waste will be disposed of
in a RCRA Subtitle-D facility.  After May 8,1992,
this ROD provides for a  contingency remedy,
which includes offsite thermal  treatment  of
organic wastes, and treatment and disposal of
inorganic  wastes  in  accordance with  LDR
requirements. The estimated present worth cost
for  this  remedial  action,  assuming  offsite
disposal without treatment, is $672,400, which
includes an annual O&M cost of $86,000.

PERFORMANCE STANDARDS OR GOALS:

Removal  of contaminated  soil and debris will
ensure that  Federal and State regulations for
ground and surface waters are  not exceeded.
Clean-up criteria  will be based on background
levels found in offsite and native soil samples.
There  were  no   chemical-specific ARARs
provided for soil.

The site overlies a bedrock aquifer that is used
as a regional drinking water source. In addition,
three streams are located onsite that discharge to
nearby Bound Brook.  From the 1950's until 1964,
Chemsol,  Inc.,  recovered  and  reprocessed
solvents and materials  received from various
companies  through activities such as mixing,
blending, and distillation. The site was closed in
1964  after   a series  of industrial accidents,
explosions, and  fires.   In 1978, the site was
purchased by Tang Realty Corporation. In 1984,
as a  result of previous  accidents, the  State
required Tang   Realty   to  investigate  site
contamination and to develop a remedial plan.
In 1988, Tang Realty removed 3,700 cubic yards
of PCB-contaminated  soil and discovered several
thousand small (less than 1 gallon) containers of
unidentified wastes. In October 1991, the drums
were  removed  of  and  disposed  of  offsite.
Between 1980 and 1990, sampling of residential
wells  indicated  the   presence  of  organic
contaminants and PCBs.   As  a result, the
township extended municipal water service to
the affected area. This ROD provides an interim
remedy to restrict the offsite migration of highly
contaminated ground water. Subsequent actions
will address ground  water contamination at a
depth of greater than 130 feet, offsite ground
water contamination, as well  as air and soil
contamination.  The  primary contaminants of
concern affecting the ground  water are  VOCs
including benzene, toluene, and xylenes; other
organics including pesticides and phenols; and
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:

The  selected  remedial  action for this interim
remedy includes installing  a  ground  water
collection trench, which will  extend  from the
surface of the site down'to approximately 10 to
15 feet below the surface; installing three ground
water extraction wells to a depth of 130 feet;
constructing  an onsite treatment  plant and
treating contaminated ground water  using air
stripping,  biological  filtration,  and  activated
carbon adsorption; treating and disposing sludge
generated  by the treatment processes offsite;
discharging the  treated ground water onsite via
an above-ground pipe to the stream flowing
along  the  eastern  property boundary; and
conducting ground and surface water monitoring
to measure the potential migration of hazardous
substances from the site. The estimated present
worth cost for this remedial action is $7,700,000,
which includes an annual O&M cost of $915,000
for 5 years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water clean-up goals
are based on the more stringent of State  or
Federal standards and include arsenic  0.50 ug/1

                                    March 29,1991
SITE HISTORY/DESCRIPTION:

The one-acre Circuitron site is a former electronic
circuit  board  manufacturing  facility  in  East
Farmingdale,  Suffolk  County,  New  York.
Surrounding   land  use  is  industrial.    A
23,500-square-foot building and a paved parking
area account for 95 percent  of the site, and the
remaining  portion is a  small  unpaved  area
behind the building.  From 1961  to 1986, circuit
board manufacturing operations including metal
plating were conducted onsite.  Several onsite
areas   were  used   for  discharge  of
process-generated  wastes  including  one
authorized and two unauthorized leaching pools
located beneath the parking area, two cesspools,
and storm drains.  At least two unauthorized
leaching pools are located beneath the floor of
the plating room.  In  1984 and 1985, Circuitron
agreed to remediate all leaching pools and storm
drains, remove all hazardous materials from the
site, and  conduct ground  water monitoring.
However, before abandoning  the premises in
1986,  Circuitron  remediated  only  one
unauthorized leaching pool  under the building
and installed  monitoring  wells.   In 1989, EPA
removed  20 waste drums  and   contaminated
debris  from  inside  the  building  and  three
above-ground  tanks  from  the  rear  of  the
building, and emptied two underground storage
tanks. Further EPA site investigations from 1988
to 1990  have  characterized  contaminants and
contaminated  media.   This  ROD  addresses
contaminated onsite soil and sediment.  Ground
water remediation will  be addressed  in a
subsequent ROD.  The primary contaminants of
concern affecting the soil, sediment, and debris
are VOCs including benzene, PCE, TCE, toluene,
and  xylenes;  other organics including PAHs,
PCBs, pesticides, and  phenols; and  metals
including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating highly  VOC-contaminated soil  in the
southwest corner of the site using in-situ vapor
extraction;  treating  emissions  using  carbon
adsorption and  disposing of any spent carbon
residuals offsite; excavating contaminated soil,
sediment, and debris from the leaching pools,
cesspools, and storm drains inside and outside of
the building; incinerating these materials offsite,
with   offsite  disposal   of   any   residuals;
decontaminating the building by vacuuming,
incinerating, and disposing of 53 cubic yards of
sediment, accumulated dust, and debris offsite;
replacing  the concrete  floor  overlying  the
excavated leaching pits under the building; and
repaving the parking  area.    The  estimated
present worth cost for this remedial action is
$685,675, which includes an annual O&M cost of
$3,850 for 4 years.

PERFORMANCE STANDARDS OR  GOALS:

Performance standards  for in-situ soil  vapor
extraction are based on leachability modeling,
and  include  1,1,1-TCA  1 mg/kg and  TCE
1.5 mg/kg.

                                     March 29, 1991
SITE HISTORY/DESCRIPTION:

The 35-acre Colesville Municipal Landfill site is
a former  municipal  and industrial  landfill in
Colesville, Broome County, New York. Land use
in the area is rural, and wetlands and woodlands
are present in the vicinity of the site. Many of
the 1,921 residents living within 3 miles  of the
site use ground water from shallow and deep
aquifers and springs as their  drinking water.
From 1969 until its closure in 1984, the landfill
accepted  primarily  municipal  solid  waste,
although some drummed industrial wastes were
accepted from 1973 to 1975.  The majority of the
468,000 cubic yards of waste was  disposed
within  three trenches at the  site, and the drums
were either buried intact, punctured, or crushed.
In  1983  and  1984,  private investigations
identified  that upper portions of the ground
water beneath the site and in the vicinity of the
site were  being contaminated  by the landfill.
The county provided temporary water supplies
and carbon  filters to affected  residences, and
conducted well monitoring.  This ROD provides
a final  remedy for the landfill waste and soil,
leachate   seeps,   associated   contaminated
sediment,  and ground  water.   The primary
contaminants of  concern   affecting  the soil,
sediment,  debris, and ground water are  VOCs
including benzene, PCE,  TCA, TCE; and metals
including arsenic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
cutting and regrading the sides and surface of
the landfill; constructing lined leachate collection
trenches; installing a multi-media cap over the
existing landfill; installing a gravel gas venting
layer  in  the landfill, with a filter fabric layer
placed over the gravel; seeding and mulching
the top soil layer  of the landfill; pumping and
treatment of  the  contaminated  ground  water
beneath and downgradient of the landfill using
air  stripping  and  metals  treatment,  and
discharging the treated water onsite to surface
water  after  disinfection  by an  ultra-violet
disinfection, if required; constructing a  water
supply system for present and future affected
residences, and  providing temporary   water
supplies and  carbon filtration units to affected
residences  until  construction  is  completed;
conducting long-term ground water monitoring;
and   implementing  institutional   controls
including deed restrictions, and site  access
restrictions such as fencing, as necessary. The
estimated present  worth cost for this remedial
action  is $5,135,000, which includes an annual
O&M cost of $250,000 for 4 years.

PERFORMANCE  STANDARDS OR GOALS:

Chemical-specific ground water  cleanup goals
are based on the  more stringent of State  or
Federal MCLs including benzene 5 ug/1 (State),
PCE 5  ug/1 (State), TCE  5 ug/1 (State), toluene
5 ug/1 (State), and xylenes 5 ug/1 (State).

INSTITUTIONAL CONTROLS:

Deed   restrictions  will  be  implemented,  if
necessary, to prevent the installation of drinking
water wells at the  site  and restrict activities
which could affect the integrity of the cap.

SITE HISTORY/DESCRIPTION:

The 8.5-acre Conklin Dumps site is an inactive
municipal landfill in Conklin, New York.  Land
use in the area is rural. The site consists of two
municipal landfills referred to as the upper and
the lower landfills. The lower landfill is adjacent
to the 100-year floodplain of the Susquehanna
River, and is bordered by wetlands. Portions of
the landfill were operational between  1964 and
1975, and approximately 80,000 cubic meters of
waste material were disposed of onsite during
this time.   In  1985,  private investigations
identified the presence of leachate seeps from the
site and  low levels of contaminants in ground
water.  This first ROD addresses containment of
landfill   leachate,   and   remediation   of
contaminated ground water as a final remedy.
The primary contaminant of concern affecting
the leachate and ground water is chloroethane, a
VOC

SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
cutting and regrading the landfill; installing a
gravel gas  venting layer and multi-media cap
over the  landfill material;  installing a leachate
collection system  and  leachate    collection
trenches or toe drains at the upper landfill, and
discharging leachate discharged offsite to a
POTW with or  without pretreatment; allowing
natural degradation to reduce the contamination
in ground water; monitoring ground water; and
implementing  institutional  controls  including
deed, land, and ground water use restrictions,
and site access  restrictions such as fencing.  If
the POTW is not available, the leachate will be
treated onsite using air stripping,  followed by
discharging the  treated effluent onsite to surface
water. The estimated present worth cost for this
remedial  action  is $4,352,078, which includes an
annual O&M cost of $86,669 for 30 years.
PERFORMANCE STANDARDS OR GOALS:

Natural degradation is expected to reduce the
concentration of chloroethane to below the State
level of 5 ug/1  within 7 to 9  years.  Leachate
treatment levels were not specified, but will meet
NPDES requirements.

INSTITUTIONAL CONTROLS:

Deed   restrictions  will  be  implemented  as
necessary.  These include measures to prevent
the installation of drinking water wells, and to
maintain the integrity of the cap.

CURCIO SCRAP METAL, NJ
June 28, 1991
SITE HISTORY/DESCRIPTION:
The 1-acre Curcio Scrap Metal site encompasses
two active scrap metal recycling businesses and
associated warehouses in Saddle Brook
Township, Bergen County, New Jersey. Land
use around the site is mixed industrial and
residential. Surface water drainage from the site
empties into Schroeder's Brook, located a few
hundred feet from the property, which drains
into a nearby lake. The site is situated above the
Brunswick Formation, which is a sole source
aquifer. This formation supplies potable water
to the public and private wells in the area. Since
1975, Curcio Scrap Metal, Inc. (CSMI) and Cirello
Iron and Steel Company (CISC) have recycled
scrap metals products onsite. In 1982, the State
identified cut electrical transformers stored
onsite, and pools of black oily fluid, which had
collected on the ground under and near the
transformers. Samples taken from this area and
from onsite soil in 1984 revealed contamination
by VOCs, organics, and metals. In 1985, the
State discovered an oil spill in a nearby pond,
approximately 200 feet from the Property. The
State determined that CISC was responsible for
the spill of approximately 200 gallons of
hydraulic fluid on the property and directed
CISC to remove contaminated soil. CISC
reportedly removed the bulk of the soil and
stored it in another onsite area. EPA issued an
Administrative Order on Consent to the PRPs on
May 27, 1988. Remedial Investigation activities
were initiated in 1989 by the PRPs under the
terms of this Order. In 1989, CISC caused a spill
of PCB-contaminated oil into onsite soil, and the
State required CISC to excavate and drum the
resulting contaminated soil. During the RI/FS,
PCBs and vinyl chloride, as well as other
contaminants were detected in the onsite ground
water. This ROD provides a final remedy for the
first operable unit (OU1), the approximately
1300 cubic yards of contaminated onsite soil.
Future RODs will address other
ground and surface water contamination. The
primary contaminants of concern affecting the
soil are PCBs and metals including lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating, incinerating, and disposing of 1,800
cubic yards of PCB- and metal-contaminated soil
above action levels at an offsite RCRA/TSCA
incineration facility, along with any resulting
ash. The estimated present worth cost for this
remedial action is $7,500,000. There are no O&M
costs associated with this remedial action.
PERFORMANCE STANDARDS OR GOALS:
All soil contaminated in excess of soil action
levels for metals and greater than PCB 1 mg/kg
will be excavated and treated offsite.
Chemical-specific goals for soil are based on
State soil action levels, and include
lead 250 mg/kg to 1000 mg/kg.

                                    March 29, 1991
 SITE HISTORY/DESCRIPTION:

 The Endicott Village Well Field site consists of a
 municipal well, the Ranney Well, and its zone of
 influence, and is located  in  Endicott, Broome
 County,  New York.   Ground  water  pumped
 from  the well serves as the  primary  drinking
 water source for the area.  Land use in the area
 of  concern includes a  golf course, a  sewage
 treatment plant, an airport,  a few industrial
 tracts, two inactive landfills,  and the  Endicott
 Landfill.    The  Endicott Landfill  accepted
 municipal and industrial  waste from the  late
 1950's until 1975, and has been used to compost
 sludge from the  onsite sewage treatment plant
 since  1982.   In 1981, EPA  detected VOC
 contamination in the Ranney Well, which was
 confirmed  by  subsequent   State and local
 investigations from 1984 to 1987.  Consequently
 in  1983,  local authorities installed a  diffused
 aeration air stripping unit on  the Ranney Well,
 and in  1984  a  purge  well  was installed  to
 intercept VOCs before  impacting the Ranney
 Well.  A 1987 ROD provided for installation of a
 packed column air stripper to treat water from
 the Ranney Well. In 1988, EPA identified  the
 landfilled materials in the Endicott Landfill as
 the   probable   source   of   ground  water
 contamination, and determined that the purge
 well did not adequately prevent the movement
 of contaminated  ground water to the Ranney
 Well.   This ROD addresses management of
 migration of  the contaminant plume as  an
 interim remedy. Final restoration of the aquifer
and remediation  of source material  will be
addressed in a subsequent ROD.  The  primary
contaminants  of  concern affecting the ground
water are VOCs  including benzene, PCE, and
TCE.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
upgrading the existing purge well system by
installing an additional purge well between the
landfill and the Ranney Well; pumping ground
water from the purge well and discharging the
water onsite to the sewage treatment plant, or
treating the water prior to discharge,  based on
the results of purge well testing; and monitoring
purge well water.  The estimated present worth
cost for this  remedial action, assuming that no
treatment will be required is $376,000, which
includes an  estimated annual O&M cost of
$24,000 for 30 years.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 540-acre Fibers Public Supply Wells site is in
Guayama, Puerto Rico.  The site includes an
active pharmaceutical plant (AWPI); two former
manufacturing   facilities,   one  of   which
encompasses two former settlement lagoons and
a soil disposal area; and five public supply wells.
Land use in the area is mixed agricultural and
light industrial.   The site overlies a  class II
aquifer. In addition, the Caribbean Sea is located
2 miles south of the site.  From  1966 to 1976,
Fibers  International  Corporation  (FIC)
manufactured nylon fibers onsite.  From 1976 to
1980, Chevron  Chemical Company (CCCPR)
expanded  the operations of  the  FIC  plant to
include the production of polypropylene fibers.
Both FIC and CCCPR operations used organic
solvents and degreasing solvents in their onsite
process. Wastewater containing these solvents
was directed to two settling lagoons, through the
process sewer system for preliminary treatment,
before  being piped  to an  offsite biological
treatment system.  FIC lined the lagoons in  1969
to reduce the seepage of treatment wastewater.
In 1978, CCCPR installed an onsite system for
treating process and sanitary wastewater, and
the treated effluent was directed to the settling
lagoons before  offsite discharge  to  the  sea.
CCCPR ceased onsite operations in 1980.  State
and private site investigations in 1983 revealed
the presence of elevated levels of organics and
inorganics in soil and ground water.  Between
1984 and 1985, AWPI remodeled the  facilities,
and in 1985 began pharmaceutical manufacturing
operations.   Also  in 1985,  AWPI excavated
portions of the settling lagoons and enlarged the
stormwater retention pond to encompass the
lagoon area. AWPI excavated 2,500 cubic yards
of the lagoon sludge and asbestos-contaminated
liner material, and deposited  the material at an
onsite soil disposal area.  This ROD addresses a
final remedy for source contamination in the soil
disposal area and ground water.  The primary
contaminants of concern affecting the soil, debris,
and ground water are VOCs including PCE and
TCE; other organics; metals including chromium
and  lead;  and   other  inorganics  including
asbestos.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating 9,010 cubic yards of contaminated
material  from  the  soil  disposal  area  and
transporting  the  soil  offsite  to  a  landfill
authorized to accept asbestos; conducting soil
sampling; controlling dust during remediation to
prevent exposure and to protect workers and the
local community during the transportation of
asbestos-containing material (ACM); restoring
and covering the excavated area with 6 inches of
fill  and  6 inches of top  soil,  followed  by
revegetating  the  area; onsite  pumping  and
treatment of the 200-acre contaminated ground
water plume from  five  recovery wells using
filtration and air stripping, and discharging the
treated water onsite to a nearby irrigation canal
to recharge the aquifer; and installing monitoring
wells near the coastline to monitor potential salt
water encroachment.  The  estimated  present
worth cost for this remedial action is $6,686,591,
which includes an annual O&M cost of $270,868
for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Soil goals  for asbestos are based on NESHAPs
under the CAA, which consider that materials
containing asbestos in concentrations exceeding
1 percent be regarded as ACM. Ground water
clean-up goals are based on State and Federal
MCLs. Goals for soil include asbestos 1 percent
by volume.   Chemical-specific ground water
goals include PCE 0.005 mg/1 (MCL) and TCE
0.005 mg/1 (MCL). EPA may invoke an ARAR
waiver  for ground  water if the remediation
program indicates that  reaching MCLs in the
aquifer is technically impracticable.

FORT DIX LANDFILL, NJ
September 24, 1991
SITE HISTORY/DESCRIPTION:
The 126-acre Fort Dix Landfill site is an inactive
landfill located in the southwest section of the
U.S. Army Fort Dix Military Reservation,
Pemberton Township, Burlington County, New
Jersey. The site is surrounded by military
housing developments, a hardwood swamp, and
a densely vegetated hardwood forest. The site is
bordered by Cannon Run Stream, located on the
east side of the landfill, and an unnamed stream
located northwest of the landfill. From 1950
until its closure in 1984, the site was used and
operated by the Fort Dix Military Reservation to
dispose of various wastes including household
waste from the military base, paints, thinners,
demolition debris, ash, and solvents. From 1968
to 1984, McGuire Air Force Base also used the
landfill for waste disposal. Landfilling
operations consisted of excavating a series of
parallel trenches and filling with waste materials.
Waste disposal began at the northern portion of
the landfill in 1950 and proceeded in a southerly
direction to the southern boundary of the
landfill. In addition to the landfill, during 1982,
the Army used a pit in the southwestern area of
the site to dispose of mess hall grease and
degreasing agents. A 1982 State investigation
revealed ground water contamination beneath
the site that had resulted from landfill leachate.
This ROD addresses final source control at the
site; however, if additional investigations reveal
significant increases in unacceptable risk to
human health and the environment, then
additional remedial actions will be proposed.
The primary contaminants of concern affecting
the soil and debris are VOCs including benzene
and toluene; other organics including PAHs; and
metals including chromium and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the 50-acre southern portion of the
landfill with a clay or geomembrane cap;
developing a soil erosion and sediment control
plan; long-term ground water, surface water, and
air monitoring; and implementing institutional
controls including deed, land, and ground water
use restrictions, and site access restrictions such
as fencing. The estimated capital cost for this
remedial action is $12,600,000, with an annual
O&M cost of $218,900 for the first 2 years and
$199,900 for years 3-30.
PERFORMANCE STANDARDS OR GOALS:
Not applicable.
INSTITUTIONAL CONTROLS:
Institutional controls including land use, ground
water use, and deed restrictions will be
implemented at the site.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The Frontera  Creek site  is composed  of  13
industrial facilities and 200 acres of associated
lagoons  within the municipality  of Humaco,
Puerto Rico.  The site includes Frontera Creek,
the industrial properties adjacent to the  creek,
the Frontera lagoons, and the Ciudad Cristiana
housing  development located  adjacent to the
creek.  Land surrounding the site consists of
mixed residential and industrial areas, and a
wildlife  refuge.   From  1971 to 1981, several
industries within  the site  including Technicon
Electronics used  mercury  in  manufacturing
processes and discharged  wastewater directly
into Frontera Creek.  The Commonwealth of
Puerto Rico Environmental  Quality Board  (EQB)
fined Technicon in 1978  for these processes,
resulting  in  the  cessation  of its mercury
discharges to the creek. During investigations in
1986, EPA identified mercury in surface soil and
sediment on Technicon property associated with
the  storage,  use,  or discharge of  mercury-
containing compounds.  This  ROD addresses
contaminated  soil   and  sediment  on  the
Technicon property, and provides a final remedy
for the site. The primary contaminant of concern
affecting  the soil and sediment is mercury.

SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating 180 cubic yards of soil and 370 cubic
yards of sediment contaminated with  mercury;
dewatering  and   containing  the excavated
material, followed by disposing of the material
offsite at a RCRA Subtitle D or C waste facility;
pretreating   wastewater  generated   from
dewatering,  followed  by onsite discharge  to
Technicon's wastewater treatment plant, or
offsite to a local POTW; performing confirmatory
soil sampling in the remediated areas to verify
that  mercury concentrations  in  residual  and
onsite materials do  not  exceed  the clean-up
levels; and  regrading and  revegetating  the
remediated areas.  The estimated present worth
cost   for  this  remedial  action  ranges  from
$562,000 to $730,000, based on whether the waste
is disposed of as a solid or hazardous waste,
respectively. There are no O&M costs associated
with this remedial action.

PERFORMANCE STANDARDS OR GOALS:

Clean-up levels  for the soil and sediment onsite
were  established based on a  site-specific risk
assessment and  an HI=1, and  include mercury
35 mg/kg.

                                 September 26,1991
 SITE HISTORY/DESCRIPTION:

 The 3,000-square-foot Garden State  Cleaners
 (GSC) site is an active dry cleaning operation in
 Minotola, Bueno Borough, Atlantic County, New
 Jersey.  Land use in the area is residential and
 commercial, and  local residents obtain drinking
 water from the Borough municipal water supply
 system. From 1966 to the present, dry cleaning
 activities using PCE were conducted at the GSC
 site, and until 1985, wastes were discharged
 through  pipes directly into  the ground.   An
 adjacent Superfund site, the 1.2-acre South Jersey
 Clothing   Company   (SJCC)   facility,   has
 manufactured and dry cleaned military clothing
 using  PCE  and  TCE   since 1940  and  also
 discharged wastewaters onsite. SJCC also stored
 solvents  and  VOC-contaminated  wastewaters
 onsite in leaking drums and tanks.  In  1981,
 SJCC reportedly removed thirty-three 55-gallon
 drums of contaminated soil from the facility. In
 1984, State investigations showed elevated levels
 of  PCE  in ground  water  adjacent  to  and
 downgradient from the GSC and  SJCC facilities,
 and elevated levels of PCE and  TCE in onsite
 soil. SJCC installed a ground water pump and
 treatment system under a State Order in  1985,
 and in 1989, began installing a limited soil vapor
 extraction system near a TCE storage tank that
 ruptured in a 1979  fire.   This  project  was
 abandoned  with the start of EPA's RI. Because
 the GSC and SJCC sites are in proximity to one
 another and have  similar contamination, the sites
 will be remediated  concurrently.   This ROD
addresses remediation of contaminated soil and
ground water at both the GSC and SJCC sites, as
a final  remedy.  The primary contaminants of
concern affecting  the soil and ground water are
VOCs  including  benzene,  PCE,   TCE,   and
 toluene.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating onsite approximately 1,600 cubic yards
of  contaminated  soil  using   in-situ  vapor
extraction; treating the contaminated wastewater
from the vapor extraction processes onsite using
an air stripping column; treating air emissions
using carbon  adsorption units;  pumping  and
onsite treatment of contaminated ground water
using air stripping  and  carbon  adsorption;
reinjecting the treated ground water upgradient
from the site; regenerating spent activated carbon
from both treatment processes offsite; conducting
long-term   ground  water  monitoring;   and
implementing  temporary institutional controls.
The  estimated present  worth  cost  for  this
remedial action at  the GSC site is  $5,451,000,
which includes an estimated annual O&M cost of
$249,500 for 70 years.  The estimated  present
worth cost for the remedial action at the GSC
and SJCC sites is $11,169,000, which includes an
annual O&M cost of $542,000 for 70 years.

PERFORMANCE STANDARDS OR GOALS:

Federal and State agencies have agreed to jointly
establish Interim Soil  Action  Level  (ISAL)
clean-up goals of 1,000 ug/kg for PCE and TCE,
given the predominance of the two compounds
at the site. Ground water remediation goals are
based on the more stringent of SDWA  Federal
and State MCLs, and include PCE 1 ug/1 (State)
and TCE 1 ug/1 (State).

INSTITUTIONAL CONTROLS:

Temporary   institutional  controls   will   be
implemented onsite while the need for providing
home treatment units for individual residents is
evaluated.

                                 December 17,1990
SITE HISTORY/DESCRIPTION:

The 270-acre General Motors/Central Foundry
Division site is an active aluminum casting plant
in Massena, St. Lawrence County, New  York.
The site is bordered by the St. Lawrence River to
the north, the St. Regis River Mohawk Indian
Reservation (which includes Turtle Creek) to the
east, the Raquette River  to the  south, and a
manufacturing facility to the west. Surrounding
land use is mixed residential and industrial. The
site overlies a surficial  alluvial aquifer and is
adjacent to wetlands, both of which have been
contaminated.   Additional  onsite features of
concern include the unlined  North and  East
Disposal Areas and the Industrial Landfill, which
contain  contaminated soil, debris, and sludge;
four unlined Industrial Lagoons, which contain
contaminated liquids, sludge, and soil; the rivers
and creek which contain contaminated sediment;
contaminated soil on the St. Regis  Mohawk
Reservation  and on General Motors property;
and contaminated associated wetlands.   From
1959 to  1980, hydraulic  fluids containing  PCBs
were used  in  the  onsite  aluminum casting
operations.  During the 1960's,  PCB  oil-laden
wastewater was routinely discharged to one of
the four industrial lagoons resulting in sludge
buildup. Wastewaters were discharged to the St.
Lawrence  River.  During the mid-1970's, the
migration  of water and  sludge through  a
breached berm surrounding the East  Disposal
Area resulted in PCB contamination on the St.
Regis Reservation and in Turtle Creek. Further
contamination stemmed from the placement of
PCB-contaminated  soil  on  the   bank of the
Raquette River, as well as  from discharge of
surface  water  run-off  from  the site to the
Raquette River.  In 1976, a wastewater treatment
system, that included a lagoon for solids settling
was installed, and this resulted in a buildup of
PCB-laden sludge in the  onsite  lagoon.  This
PCB-laden   sludge  from   the   lagoon   was
periodically  removed to the  East and North
Disposal Areas and the Industrial Landfill. Solid
industrial  wastes were disposed  of  in the
Industrial  Landfill as well.   Investigations by
General Motors from 1985 to 1989 confirmed and
characterized onsite and offsite contamination in
soil, sediment, sludge, and ground water. As a
result, in 1988 an interim cap was placed over
the Industrial Landfill.  This ROD provides a
final remedy for all site  areas and media except
the East  Disposal  Area  and  the  Industrial
Landfill,  which  will  be  addressed  in  a
subsequent ROD. The primary contaminants of
concern affecting the  soil,  sediment,  sludge,
debris, ground water,  and  surface  water are
PCBs, and to a much lesser  degree,  VOCs
including  TCE; and other organics including
PAHs and phenols.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
dredging and excavating approximately 62,000
cubic yards of contaminated soil and sediment
from PCB "hot spots" in the St. Lawrence and
Raquette rivers,  Turtle  Creek,  and  associated
wetlands   and  riverbanks;  excavating
approximately 142,000 cubic yards  of  sludge,
soil, and debris from the North Disposal Area
and the four Industrial Lagoons (two of the four
of  the  lagoons are  inactive  and will  be
remediated currently, the two active lagoons will
be  remediated  after they are taken  out of
service); excavating approximately 49,000 cubic
yards of soil from the Reservation and General
Motors  property;  dewatering  and  treating
dredged  and   excavated   material   using
bioremediation, another equivalent treatment, or
incineration based on  treatability test  results;
disposing  of  residuals and  material  with
low-level  contamination  onsite,  placing  a
vegetated cap over the residuals; pumping and
onsite treatment of contaminated ground water;
discharging the treated  water onsite to  surface
water; implementing interim surface runoff

                                     March 29,1991
 SITE HISTORY/DESCRIPTION:

 The Genzale  Plating site is  an electroplating
 facility, which occupies a 24,000-square-foot area
 in Franklin Square, Nassau County, New York.
 Land  use  in  the   area  is  predominantly
 residential,  with  a  wetlands  area  located
 approximately 3 miles southeast of the site. The
 site overlies a Gass II aquifer, which is tapped
 by three water supply wells within 1.5 miles of
 the  site.    Since  1915,  the  Genzale  Plating
 Company, Inc., operated an electroplating facility
 onsite. Records indicate that copper, silver, zinc,
 cadmium, nickel, and chromium compounds, as
 well as acids  and cleaners, were used during
 plating processes.  Wastewaters generated from
 the electroplating operations were discharged to
 four subsurface leaching pits.  Following a 1981
 county inspection, the owner was required to
 discontinue onsite contaminant discharge to the
 leaching pits. Testing of the wastewater samples
 from  the   pits  indicated   heavy   metal
 concentrations  in  excess of  State  discharge
 standards.     In  1982,   36   cubic  yards  of
 contaminated material were excavated; but the
 entire excavation was never completed. In April
 1983, a State investigation determined that onsite
 contaminants presented a potential public health
 threat because the site is in close proximity to
 public water  supply  wells.   The primary
 contaminants of concern affecting the soil and
 ground water are VOCs including PCE and TCE;
 other organics including PAHs;  and  metals
 including arsenic, chromium, and lead.

 SELECTED REMEDIAL ACTION:
The selected interim remedial action for this site
includes  treating soil  using in-situ vacuum
extraction and vapor phase carbon adsorption to
control emissions, followed by excavating 1,600
cubic yards of the treated soil and 480 cubic
yards of topsoil and material from the leaching
pits,  followed by offsite treatment and disposal;
backfilling the  excavated areas with clean soil;
 pumping and treatment of ground water using
 precipitation to remove metals, followed by air
 stripping, with  reinjection  onsite and offsite
 disposal of treatment residuals. The estimated
 present worth cost for this remedial action is
 $6358,700, which includes an annual O&M cost
 of $223,800.

 PERFORMANCE STANDARDS OR GOALS:

 Chemical-specific soil clean-up goals include
 TCE 1 mg/kg. Ground water treatment will be
 designed to reduce the metals concentrations in
 the treated ground water below the Federal and
 State ground water standards.

                                 September 11,1991
 SITE HISTORY/DESCRIPTION:

 The 57.5-acre Global Landfill is an inactive solid
 waste disposal facility in Old Bridge Township,
 Middlesex County, New Jersey. The facility is
 bordered by wetlands to the northeast, southeast,
 and southwest, and a former sand borrow pit
 and wooded area to the northwest. Land use in
 the area is primarily residential.  Onsite features
 include a 51-acre landfill, a 6.5-acre northwest
 landfill extension, and an  inactive  1.7-acre
 leachate  collection  pond.   Municipal  water
 supply wells are located approximately 1 mile
 north of the landfill. From 1968 until its closure
 in 1984, the Global Landfill site was used for
 non-hazardous solid waste disposal. As a result
 of a slope failure in 1984, landfill  wastes were
 exposed, the dyke was breached, and the wastes
 spilled  into  an  adjacent  wetlands  area.
 Subsequently,  the State ordered all onsite
 disposal operations to cease. From  1988 to 1991,
 EPA and State site investigations identified 63
 buried 55-gallon drums containing hazardous
 wastes including VOCs, organics, and metals
 within both the  waste mound and northwest
 extension. This ROD addresses Operable Unit 1
 (OU1), the landfill wastes.  A second ROD will
 address  possible offsite  ground  water  and
 surface water contamination, and wetland areas,
 as OU2.  The primary contaminants of concern
 affecting the  soil  and sediment  are VOCs
 including  benzene, PCE,  TCE, toluene, and
 xylenes; other  organics; and metals including
 arsenic, chromium, and lead.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the landfill with a  synthetic and clay
cap;  constructing  a soil  stabilization  berm;
constructing and operating a gas management
system, and stormwater and leachate collection
systems; pumping leachate and condensate from
the gas collection system to a holding tank, and
subsequently transporting the  waste offsite for
treatment and  disposal  (this constitutes  an
interim remedy for  the leachate); disposing of
sludge offsite at a RCRA facility; implementing
a monitoring program to ensure the effectiveness
of the remedy; mitigating any affected wetlands;
and implementing site access restrictions such as
fencing.  Onsite leachate  treatment  that would
replace the  offsite  leachate  treatment  and
disposal provided for in this ROD,  may be
initiated as part of the ground  water remedy in
the next ROD, as part of the preferred  leachate
management alternative.   This  may  include
treatment using powdered activated  carbon,
nitrification   and   denitrification,  and   UV
disinfection, followed by discharging the treated
effluent onsite to the Cheesequake Creek.  The
estimated present worth  cost  of this remedial
action is $30,353,200, which includes an annual
O&M cost of $865,100 based on onsite treatment
of leachate.

PERFORMANCE  STANDARDS OR GOALS;

A waiver of the New Jersey Hazardous Waste
Landfill Closure Regulations will be required on
the basis of technical impracticality  due to  the

                                  September 27,1991
 SITE HISTORY/DESCRIPTION:

 The 80-acre Hertel Landfill site consists of a
 13-acre former municipal landfill and adjacent
 land  in  Plattekill, Ulster County,  New York.
 Land  use  in  the  area   is  predominantly
 residential, with wetland areas adjacent to the
 site.   The site overlies two natural  aquifers.
 From 1963 to 1975, Hertel Enterprises used the
 site for the disposal of municipal solid waste. In
 1975, the landfill was purchased by Dutchess
 Sanitation Services, which had been hauling and
 disposing of refuse from Dutchess County in the
 Hertel Landfill since 1970.  It is estimated  that
 240,000 cubic yards of waste  were disposed
 onsite during landfill operations.  In 1976, the
 site was shut down for a variety of violations,
 including illegal dumping of industrial wastes
 and violating a town ordinance prohibiting the
 disposal of non-local waste.  As a result of these
 improper disposal practices, a number of State
 investigations were conducted, which identified
 contamination by  various organic compounds
 and metals in the onsite soil and ground water.
 This  ROD  addresses soil  contaminated  by
 landfill wastes, and ground water contaminated
 by landfill leachate. The primary contaminants
 of concern affecting the soil,  sediment, debris,
 and ground water are VOCs including benzene,
 toluene, and xylenes; other organics  including
 phenols;  and  metals   including   arsenic,
 chromium, and lead.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
regrading and compacting the landfill mound to
provide a stable foundation for cap placement;
constructing a  13-acre multi-layer cap over the
landfill with an associated gas venting system;
sampling soil along the western portion of the
disposal area to determine the need to extend
 the cap or to consolidate the soil beneath the cap;
 monitoring  air to ensure  that air emissions
 resulting from the cap construction meet ARARs;
 ground water pumping and treatment using an
 innovative  treatment  system  consisting  of
 precipitation and membrane microfiltration to
 remove metals and solids, and an ultraviolet
 light and hydrogen peroxide oxidation system to
 remove organics; performing a treatability study
 to  demonstrate   the  effectiveness  of  the
 innovative   technology;   implementing   a
 contingency remedy consisting of precipitation,
 clarification, and filtration to remove metals and
 suspended solids,  and  carbon absorption  to
 remove organic compounds, if the treatability
 study  indicates  that  the  selected innovative
 ground  water  treatment  technology  is  not
 effective; discharging the treated water onsite,
 and  disposing  of  treatment  residuals  in
 accordance   with   RCRA   Land   Disposal
 Restrictions; evaluating and mitigating affected
 wetlands; conducting ground water monitoring
 to observe flow patterns above and below the
 landfill; and implementing institutional controls
 including deed  restrictions,  and  site access
 restrictions such as  fencing.   The estimated
 present worth cost for this remedial action is
$8,207,000, which includes an annual O&M cost
of $267,000  for years  0-12, $162,800 for years
 13-17, and $31,000 for years 18-30.  The present
 worth  cost  for  the  contingency  remedy  is
$8,774,000, with the same O&M costs.

PERFORMANCE STANDARDS OR GOALS:

Capping will prevent direct contact exposure to
contaminated soil, and will result  in risks that
are less  than  EPA's target levels of  10"6 for
carcinogenic risks and an HI=1.  Ground water
clean-up goals are  based on Federal and State
standards, and include  total xylenes 5  ug/1
(State).

                                  September 24,1991
 SITE HISTORY/DESCRIPTION:

 The approximately 20-acre Juncos Landfill site is
 an inactive municipal waste landfill in the City
 of Juncos, Puerto Rico, Land use in the area is
 predominantly  residential,  with  a  housing
 development located along the northern border
 of the site. Two unnamed tributaries are located
 outside the eastern and western borders of the
 site and flow to the Rio Gurabo.   Municipal
 wastes including broken and/or intact mercury
 thermometers, were disposed of at the site from
 1957 to 1977, and in 1981, the site was closed.
 Several EPA investigations revealed the presence
 of mercury and VOCs in the soil, offsite leachate,
 and air. In 1984, under an Administrative Order,
 EPA required the PRP to place a soil cover over
 some portions of the landfill where wastes were
 exposed, and to assess risks posed by potential
 mercury contamination. This ROD is the first of
 two  operable  units (OUs)  and  addresses
 contaminated soil and soil/leachate.  A future
 ROD  will provide for remediation of potential
 ground water contamination  as a  result  of
 migrating leachate,  as  OU2.   The  primary
 contaminants of  concern  affecting the soil and
 debris are VOCs;  other organics  including
 phenol; and metals including arsenic, chromium,
 lead, and mercury.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
constructing a single barrier cap over the landfill
to reduce  surface infiltration,  prevent  direct
contact, limit gas emissions, and control erosion;
installing a passive landfill gas venting system,
which could be converted to an active system if
monitoring shows this is needed; clearing and
grubbing existing vegetation on the landfill area,
and  regrading  the  landfill;  installing,  if
necessary, a leachate control system composed of
a  leachate storage  system   prior  to  offsite
treatment of  leachate;  providing for erosion
control   appurtenances  including  drainage
channels,  and  stilling and sediment  basins;
conducting  long-term  monitoring   of   air,
sediment, surface water, and leachate; relocating
families  living in homes  located along  the
immediate north face of the landfill during the
construction   phase;  and  implementing
institutional controls including deed restrictions,
and  site access restrictions including fencing.
The  estimated  present worth cost  for  this
remedial action is $4,420,000, which includes an
annual O&M cost of $176,100.

PERFORMANCE STANDARDS OR GOALS:

                                      May 15,1991
 SITE HISTORY/DESCRIPTION;

 The Love Canal site is an inactive hazardous
 waste site located in Niagara Falls, New York.
 The 19-acre 93rd Street School site, one of several
 operable units for the Love Canal Superfund site,
 is the focus of this ROD. This subsite is located
 less than one mile northwest of the Love Canal
 disposal area and is within  the Love Canal
 Emergency Declaration Area.   Onsite  features
 include the 93rd Street School  building and
 adjacent vacant land.  The site is bordered by
 Bergholtz Creek to the north  and residential
 properties to the east, west, and south.  From
 1942  to 1953, Hooker Chemicals and  Plastics
 Corporation   (now  Occidental  Chemical
 Corporation)  disposed of  over 21,000  tons of
 various  chemicals   including  dioxin-tainted
 trichlorophenols at the Love Canal site.  In 1950,
 after the site was deeded to the City of Niagara
 Falls Board of Education, the 93rd Street School
 was built.  In 1954, a second school,  the 99th
 Street  School,  was  built adjacent   to  the
 mid-portion of the Canal. Before construction of
 the 93rd Street School, a  drainage swale had
 crossed the site. In 1954, the site was graded to
 its present contours with  approximately 3,000
 cubic  yards of fill materials including  fill from
 the 99th Street School.    The  fill material  is
 reported to contain fly ash and BHC (a pesticide)
 waste.  During the mid-1970's,  contaminated
 leachate migrated to the surface of the Canal, to
 some residential basements adjacent to the Canal,
 and through sewers to area creeks. Those homes
 have  been demolished,  and the sewers  and
creeks in the Love Canal Emergency Declaration
 Area have been remediated.  In 1980, the 93rd
Street School was closed because of public health
concerns related to the potentially contaminated
fill material.  Investigations conducted  in 1988
revealed the presence of VOCs, other organics,
and  metals in  the  soil.   During previous
investigations, it was determined that low level
contamination present in the ground water
compared to the ground water quality in  the
area and did not pose an exposure threat to the
concerned population. A 1988 ROD addressed
source   control  through   excavating  and
solidifying/stabilizing the excavated  material,
placing the  material into the same unit, and
capping with a low permeability soil cover. The
remedial action was not implemented and  has
now been reevaluated in light of the Niagara
Falls Board of Education's 1989 plan to  restore
the 93rd Street School as an educational  facility
and to address objections to reopening the school
if contaminated soil  remains onsite.  This ROD
amends the 1988 ROD,  and addresses final
remediation  of onsite contaminated soil through
excavation and offsite disposal.   The primary
contaminants of concern affecting the soil  are
VOCs  including toluene and xylenes; other
organics  including PAHs and pesticides;  and
metals including arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION;

The amended  remedial  action  for  this  site
includes excavating and disposing of offsite 7,000
cubic yards of contaminated soil from hot spot
areas; backfilling excavated areas with site soil of
lower contamination; and capping and regrading
the area with fill material. The estimated present
worth cost for this amended remedial action is
$2,250,000, which does not include O&M costs.

PERFORMANCE STANDARDS OR GOALS:

Soil action levels were not provided.  Ground
water  clean-up goals were  waived due to
technical impracticability.

SITE HISTORY/DESCRIPTION:

The 2-acre Mattiace  Petrochemicals site is an
inactive liquid storage and redistribution facility
in  Glen Cove,  Nassau County,  New  York.
Surrounding  land  use  is primarily  industrial.
Glen Cove Creek,  a  potential wetland area, is
located  south of the site.  The site overlies a
system  of  three unconsolidated  sedimentary
aquifers, of which the  surficial Upper Glacial
Aquifer   has   been  affected  by   onsite
contamination.   From the  mid-1960's to 1986,
organic  solvents were stored, blended, and
repackaged onsite.   Onsite  features involved
with the operation included a  metal Quonset
hut, a concrete fire  shed,  a leaching pond, a
partially covered concrete loading dock, and
32 underground  and 24 above-ground storage
tanks. Drums were reconditioned onsite, and the
resulting  water/sol vent   mixtures   were
discharged to above-ground tanks or to an onsite
leaching pond.  A  solvent water separator was
used to collect overflow from the above-ground
tanks for discharge to the leaching pond.  There
is evidence, however, that overflow from these
tanks may have been discharged directly into the
soil. In 1988, EPA characterized and disposed of
100,000 gallons of hazardous liquids offsite from
approximately 24 above- and 32 underground
storage   tanks.     In 1989,   a second  EPA
investigation identified approximately 25 buried
drums and numerous other containers that were
leaking   contaminated  material    into   the
surrounding soil and ground water.  A 1990
ROD provided  for removal of onsite  buried
drums   containing  sludge,  as well  as  the
associated highly contaminated soil as Operable
Unit 2 (OU2). In 1989, EPA characterized  onsite
contamination, and discovered a layer of "free
product" floating on top of contaminated ground
water and contaminated sediment in Glen Cove
Creek.   This ROD addresses remediation  of
onsite source materials, as well as management
of migration of contaminated shallow ground
water.  The primary contaminants of concern
affecting the soil, debris, and ground water are
VOCs including PCE, TCE, toluene, and xylenes;
other organics including PAHs, pesticides, and
phenols;  and  metals   including   arsenic,
chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and treating offsite 208 cubic yards of
pesticide-contaminated "hot spot" soil, possibly
by incineration, followed by offsite disposal of
residuals; backfilling excavated areas with clean
soil; treating 17,141  cubic yards of contaminated
soil using in-situ vacuum extraction, followed by
activated carbon to  control off-gases, as needed;
decontaminating and demolishing  the Quonset
hut,  24 above-ground tanks, 32  underground
tanks, and 1,360 cubic yards of  concrete and
asphalt, followed by offsite disposal; removing
15,000 gallons of "free product" using ground
water extraction wells and a skimmer pump,
followed  by offsite  treatment  and  disposal;
pumping and treatment of ground water using
precipitation and clarification as pretreatment to
remove metals, and  air  stripping to  remove
organics, and reinjecting the treated water onsite;
treating air effluent from the air stripper using
thermal treatment;  treating water effluent from
the air stripper using carbon adsorption, and
regenerating spent carbon offsite;  performing
treatability studies;  conducting a soil gas survey
to monitor off-gas  migration; and  monitoring
ground water, Glen Cove Creek sediment, and
surface water.  The estimated present worth cost
for this remedial action is $15,930,592, which
includes an annual O&M cost of $692,997 for 30
years.

PERFORMANCE STANDARDS OR GOALS:

Soil clean-up goals are based on achieving an
excess lifetime cancer risk of 10"6.

                                 September 27,1991
 SITE HISTORY/DESCRIPTION:

 The 44-acre NL Industries site is an  inactive,
 secondary lead smelting facility in Pedricktown,
 Salem County, New Jersey. Land use in the area
 is predominantly residential and industrial. The
 site is  bordered  by two tributaries  to the
 Delaware River, which receive surface discharges
 from the site.  The site overlies the  Cape May
 aquifer, a potential source of drinking water for
 local residents. From 1972 to 1984, the site was
 used to recycle lead from  spent automotive
 batteries,  and  the  unused  portions  of the
 batteries were buried  in  an onsite  landfill.
 During operations, batteries and other materials
 containing  lead were  stored  on paved and
 non-paved  areas onsite; and drums and debris
 were scattered throughout the site, within and
 outside  of  buildings, and  on  the paved areas.
 There also are approximately 1,000,000 gallons of
 contaminated  standing water and  200 cubic
 yards  of  associated sediment  at   the  site.
 Between 1973 and 1980, the State cited the PRP
 for  multiple violations  of  State air and water
 regulations. In 1989, EPA began a multi-phased
 removal action, which  included consolidating
 and  encapsulating  debris and lead-bearing
 materials into separate piles totaling 9,800 cubic
 yards of kiln slag and 200 cubic yards of lead
 oxide; removing over 40,000 pounds of toxic and
 reactive  materials;  incinerating  2,200 empty
 drums offsite; and constructing a chain-link fence
 to enclose the site.  In addition, EPA  conducted
 a Focused Feasibility Study (FFS) to address the
 remediation of slag and lead oxide piles, debris
and contaminated  building surfaces, standing
 water, and  sediment.  The FFS resulted in the
issuance of this Early Remedial Action ROD,
designated  as Operable Unit (OU2).  The nature
and extent of remaining contamination on the
site  and areas adjacent to the site in various
environmental media, such as soil, sediment,
ground  water, surface water, and  air,  are
currently being evaluated and will be addressed
as OU1 in a subsequent ROD.  The  primary
contaminants of concern affecting the slag and
lead oxide piles, sediment, debris, and standing
surface water are  metals  including  arsenic,
chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating onsite the  slag and  lead oxide piles
using solidification/stabilization and placing the
residual material onsite; decontaminating debris
and contaminated building surfaces, with offsite
treatment and disposal of debris that cannot be
decontaminated;  treating  and  disposing  of
standing  water,    wash  water   from   the
decontamination process, and  sediment offsite;
conducting  environmental  monitoring;  and
implementing institutional controls  including
land use restrictions.   The estimated present
worth cost for this remedial action is $4,987,000,
which includes an annual O&M cost of $17,000.

PERFORMANCE STANDARDS OR GOALS:

The selected remedy will attain all Federal and
State ARARs. Chemical-specific clean-up goals
were not provided.

INSTITUTIONAL CONTROLS:

Institutional   controls  including   land  use
restrictions will be implemented at the site.

                                      June 28,1991
 SITE HISTORY/DESCRIPTION:

 The 17.5-acre Nascolite site is an inactive acrylic
 and plexiglass sheet manufacturing plant in
 Millville, Cumberland County, New Jersey. The
 site lies within the New Jersey coastal plain and
 overlies clay, silt, sand, and gravel layers.  The
 majority of the site is wooded, with a wetland
 located in the southwestern portion. Land use is
 both  industrial  and  residential,  with homes
 located 1,500 feet to the east and southeast of the
 site.  Site features include six buildings, which
 served as the production facility, laboratory, and
 company offices;  and a drainage  ditch.   From
 1953 to 1980, site operations included reclaiming
 scrap material  through depolymerization and
 distillation  processes.   Residues from  these
 operations were discharged to the buried onsite
 tanks, and wastewater was discharged to the
 onsite drainage ditch.  Decay of the structures
 and asbestos fibers within the buildings pose a
 threat to site workers.  In  1980, although the
 State  ordered the  plant to stop discharging
 wastewaters into the onsite drainage ditch, well
 water  monitoring  conducted  during  1981
 identified VOC-contamination in these wells. In
 1984,  the State identified over one hundred
 55-gallon  drums  and  several  underground
 storage tanks buried onsite.  In 1987, the  State
 ordered Nascolite to remove some of the drums,
 and later during 1987 and 1988, EPA removed
 the remaining drums offsite. Perforations found
 in one of the  excavated tanks indicated the
 likelihood that VOCs and lead had leaked into
 and  contaminated  onsite  soil,  which   was
 confirmed by  subsequent sampling.   Also in
 1987, EPA assumed the lead for the site, cleaned
and cut the waste material storage  tanks into
 scrap  metal, and removed 20 cubic yards of soil
and 30 cubic yards of asbestos insulation.  In
addition, the wastes in tanks and  drums  were
sampled, bulked into 1,825 gallons of
corrosive/ignitable liquid and 134 cubic yards of
solidified  solvent sludge, and removed offsite.
A 1988 ROD addressed onsite ground water
contamination and provided for pumping and
treatment of ground water, provision  of an
alternate water supply  to affected residences,
and additional site studies. This ROD addresses
contaminated   onsite   soil,  sediment,   and
buildings. The primary contaminants of concern
affecting the soil, sediment, and debris are VOCs
including benzene,  PCE,  TCE, toluene,  and
xylenes; and metals including lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating, treating, and stabilizing 8,000 cubic
yards  of  unsaturated   and   wetlands   soil
containing lead  above 500 ug/kg; backfilling
excavation  pits   using  the   treated   soil;
transporting wetland sediment not amenable to
stabilization  offsite;  restoring   any   affected
wetlands;  conducting  asbestos  abatement,
followed by offsite disposal; demolishing site
structures   in   accordance  with  asbestos
regulations, followed by decontamination, onsite
treatment,  recycling, or  offsite  disposal  of
associated debris; and implementing institutional
controls.  The estimated  present worth cost for
this remedial action is $4,165,000, which includes
an annual O&M cost  of $31,000.

PERFORMANCE STANDARDS OR GOALS:

All unsaturated  soil contaminated with lead
above  the action level of 500  ug/kg will be
excavated and stabilized  onsite.

INSTITUTIONAL CONTROLS:

Institutional  controls will  be implemented to
ensure that the solidified mass is not disturbed.

SITE HISTORY/DESCRIPTION:

The  7,400-acre Naval  Air Engineering Center
(NAEC) site is an active air base in Jackson and
Manchester Townships,  Ocean County,  New
Jersey.   Activities conducted  onsite include
program research, engineering,  development
testing and evaluation,  and various warfare
support services. Land use in the  area includes
residential, woodland,  vast  wetlands,  and
associated  floodplain  areas.   Approximately
65,400 residents of the townships are serviced by
several municipal  supply wells located within
one mile of the site to  the southeast and north.
From 1916 to 1919, the Eddystone  Chemical
Company conducted chemical artillery testing
onsite. In 1921, the U.S. Navy took control of
the site and conducted  operations involving the
use,  handling, storage, and  onsite disposal of
hazardous substances in various onsite buildings.
Site  features  within Area C include  a barrel
storage area and fuel  station  (site 10), a fire
training  area with unlined  lagoons  and an
oil/water separator (site 16), and an onsite fuel
farm with inactive dry  wells that were removed
in 1982 (site 17). Preliminary investigations in
1983 by the U.S. Navy identified 44 onsite areas
of possible soil and ground water contamination,
and determined  that the primary sources of soil
and  ground water contamination in Area C
(comprised of sites 10, 16, and 17) were leaky
valves  and  pipes,  dispensing  pumps,  the
underground  fuel oil  tanks, overflowing dry
wells, and other accidental onsite chemical spills
and releases. In 1988, NAEC removed and
replaced the onsite tanks. This ROD provides an
interim  remedy  for contaminated  soil  and
ground  water in Area C Sites 10,  16, 17, as
operable unit 1.  The primary contaminants of
concern affecting the ground water are VOCs
including  benzene,  TCE,  and  xylenes;  other
organics including PAHs; and metals including
arsenic and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
pumping  and  pretreating ground water to
remove metals, residual amounts of free product,
and solids, followed by offsite disposal of solids
and  free product; onsite  treatment using air
stripping and vapor phase carbon adsorption to
remove VOCs, and polishing the effluent using
granular activated carbon; spray  irrigating or
infiltrating the  treated ground water over the
onsite soil; regenerating the spent carbon offsite;
and disposing of all solids, residual sludge, and
free product offsite.  The estimated capital cost
for  this remedial  action  is $700,000, with an
annual O&M cost of $100,000 for 3 years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific  clean-up goals for  ground
water will be addressed in the final remedy.

Preliminary investigations by  the Navy  from
1983 to 1986 identified  potential onsite soil and
ground water contamination in 44  site areas,
including  Area  H, site  32, which has  been
designated as operable unit  2 for  remediation.
Site 32 consists of the launching end  of five test
tracks  and  ancillary   facilities   including a
drainage system designed to receive oil and fuel
runoff from each track,  a series of dry wells, and
several   underground   storage  tanks.
Contamination in this area was thought to  have
been the result of improper disposal of wastes in
five dry wells, various spills, leaking valves, and
other poor housekeeping practices. In 1988, the
Navy excavated and removed offsite the five dry
wells,  contaminated  soil,  and  underground
storage tanks to prevent potential discharges to
ground water. This ROD provides an interim
remedy for the second operable unit (OU2), the
ground water contamination in Area H, site 32.
The focus of this OU is ground water, although
some treatment of soil may occur.  The primary
contaminants of concern affecting the ground
water are VOCs including PCE; other organics;
and metals including lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
pumping  and pretreating  ground water  to
remove metals, soil, and residual amounts of free

 SITE HISTORY/DESCRIPTION:

 The 7,400-acre  Naval Air Engineering Center
 (NAEC) site is an active air base in Jackson and
 Manchester  Townships, Ocean County, New
 Jersey.   Activities  conducted onsite  include
 program research,  engineering,  development
 testing and evaluation, and  various  warfare

 residential areas, woodlands, vast wetlands, and
 associated floodplain areas. The site lies within
 the Toms River Drainage Basin, and adjacent to
 and south of the site are commercial cranberry
 bogs  that drain into and out of the southeast
 section  of the  site.   Approximately 65,400
 residents of  the townships  are serviced by
 several municipal supply wells located within
 1 mile of the site to the  southeast and north.
 From 1916 to  1919, the  Eddystone Chemical
 Company conducted chemical artillery testing
 onsite. In 1921, the U.S. Navy took control of
 the site and conducted operations involving the
 use, handling, storage, and onsite disposal  of
 hazardous substances in various onsite buildings.
 This  ROD  addresses operable unit 3, which
 includes eight separate sites and a region known
 as Area L. The sites include a disposal area (site
 15), a gas station (site 18), an  inactive disposal
 area (site 23), a  contractor disposal area located
 along a  drainage swale  (site 26),  recovery
 systems test sites (site 27), a recovery  systems
 track  site (site 30), a parachute jump circle (site
 34), and a soil stabilization field test site (site 40).
 Area L is located in  the northwestern corner of
 the facility in the vicinity of a BOMARC missile
explosion area.  The explosion resulted in the
 limited  spread  of   a  radioacative  material,
 plutonium.  The results  of  the RI  show no
evidence of significant contamination at the eight
sites and Area L. At most sites, contaminants
 were not detected. In instances where
contaminants were  detected,  the  levels were
usually well  below State  and Federal action
levels.   Furthermore, investigations conducted
from 1985 to 1990 in Area L also concluded that
no   significant   levels   of  radiological
contamination were present in ground water,
soil, or sediment in this area.  Therefore, there
are no contaminants of  concern affecting this
site.

SELECTED REMEDIAL  ACTION:

The selected remedial action for this site includes
no further action because  no significant levels of
contaminants exist at the eight sites and Area L.
No additional action  is necessary to protect
human health or the environment. There are no
costs associated with this no action remedy.

SITE HISTORY/DESCRIPTION:

The  7,400-acre Naval Air Engineering Center
(NAEC) site, which contains many subsites, is a
naval research design and testing facility near
the Jackson and Manchester Townships, Ocean
County, New Jersey. The site lies within the
Toms River Drainage Basin and contains 1,300
acres of flood-prone areas. Land use in the area
is part residential and part undeveloped.  The
estimated 65,400 people who  reside within the
Jackson and Manchester Townships receive their
water from municipal wells.  This ROD focuses
on remediation of Area E (Site 28) within the
NAEC site. Currently, Area E features include
a former oil storage shed, former paint locker,
and five fuel storage containers. From 1957 to
1980, unknown quantities of waste oil, hydraulic
fluids, and solvents were discharged in Area E.
In 1988, the RI identified elevated VOC levels
and floating product, most likely gasoline, in the
ground water. Subsequent investigations in 1990
discovered a gasoline leak in an underground
pipe, which apparently was the source of ground
water  contamination.    Onsite  actions have
included repairing the leak and excavating and
disposing  of  65  cubic  yards  of  visually-
contaminated soil.  This ROD  provides an
interim remedy for ground water contamination.
Future  RODs  will  address  the remaining
contaminated media including a final  decision
for ground water. The primary contaminants of
concern affecting  the ground water are VOCs
including benzene, toluene,  and xylenes; and
other organics including PAHs.

SELECTED REMEDIAL ACTION:

The  selected remedial action  for this interim
remedy includes onsite pumping and pretreating
ground water using precipitation and filtration to
remove metals, solids and residual amounts of
free product, and air stripping to remove VOCs;
filtering the effluent from the treatment process
water  using  a  granular  activated  carbon
polishing filter, and  discharging the treated
water onsite in a spray irrigation and infiltration
system depending on the season; treating air
emissions  using  granular  activated  carboy-
regenerating and disposing of any spent carbon
offsite;  and disposing of  the resultant sludge
from  the  treatment  process offsite.   The
estimated capital cost for this remedial action is
$1,000,000, with an annual O&M cost of $100,000
for 3 years.

                                 September 30,1991
 SITE HISTORY/DESCRIPTION:

 The 2.1-square mile Rockaway Borough Wellfield
 site is  a  municipal  well  field in Rockaway
 Borough, Morris County, New Jersey. Land use
 in the area is predominantly residential.  The
 estimated 10,000 people who reside in Rockaway
 Borough use  the underlying glacial aquifer as
 their sole source of drinking water. Beginning in
 1980, a number of State investigations revealed
 VOC-contaminated soil, sediment, and ground
 water, which had originated from several source
 areas within the Borough. In 1981, the Borough
 constructed   a  granular  activated  carbon
 adsorption treatment  system  that  treated
 approximately 900,000 gallons per day of raw
 water pumped from the well field.  Overall, the
 system has reduced VOC concentrations in the
 municipal water supply to levels meeting State
 and Federal drinking water standards. A 1986
 ROD provided for the continued operation and
 maintenance  of the  existing  ground  water
 treatment system, for a continuation of the RI/FS
 to positively  identify additional contaminant
 sources, and for further delineation of the  full
 extent of contamination. The 1986 ROD did not,
 however,  address  ground water  restoration.
 Recently, EPA also has approved a State-initiated
 modification to the current treatment system to
 include the installation of an air stripper as the
 first stage  in the treatment process.  This ROD
 addresses final restoration of the contaminated
 onsite ground water to drinking water standards.
 A future  ROD will address  the  need  for
 remediation of the contaminant sources.  The
 primary contaminants of concern affecting  the
 ground water are VOCs including PCE and TCE;
 and metals including chromium and lead.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
onsite pumping and treatment of ground water
from two of three plumes of concern using
chemical precipitation and air snipping, followed
by reinjecting the treated ground water onsite
into   the  glacial  aquifer;   and  conducting
environmental monitoring. Under this remedial
action, a  single  treatment  facility  would be
necessary  for the two treatment  areas, and no
active remedial measures would be taken for the
third plume. The estimated  present worth cost
for  this remedial action is $17,818,000, which
includes an annual O&M cost of $1,502,000 for
27 years.

PERFORMANCE STANDARDS  OR GOALS:

Chemical-specific ground water clean-up goals
are based  on the more  stringent of Federal or
State MCLs, and include PCE 1 ug/1 (State MCL)

 SITE HISTORY/DESCRIPTION:

 The 200-acre Roebling Steel site is an inactive
 steel  wire and cable  manufacturing  facility in
 Florence Township, Burlington  County, New
 Jersey.   Site  features include a 34-acre slag
 disposal area, and 55 buildings connected by a
 series of paved and unpaved access roads. Two
 portions of the slag area lie within the 100-year
 floodplain  of the Delaware River.   A public
 playground,  known as the  Southeast  Park, is
 adjacent to the southeastern  portion of the site,
 and  land  surrounding  the  site  consists  of
 farmlands, wetlands, and forested and residential
 areas.  The Roebling Steel site produced steel
 products between  1906 and 1982.   In recent
 years, parts of the site have  been used as a
 storage facility for vinyl products, a warehouse
 facility, a polymer-reclamation facility, a facility
 for  repairing  and  refurbishing  refrigerated
 trailers and shipping containers, a storage facility
 for insulation, and an equipment storage facility
 for a  construction company.   Approximately
 1,458,000 cubic  yards of slag  material from
 steel-making processes were used to fill in a
 large portion of the bordering Delaware River
 shoreline. In addition to the slag material, other
 potential sources of contamination onsite include:
 process buildings containing chemical treatment
 baths, tanks,  pits and sumps;  a wastewater
 treatment plant;  two  sludge  lagoons;  friable
 asbestos insulation inside buildings and falling
 from  pipes; 52 railroad cars  containing fly-ash,
 dry sludge, and debris; and a landfill containing
 rubble  and  debris.   Because  the site  lacked
 properly  operated  environmental   control
 facilities, several regulatory agencies have issued
 notices of noncompliances to site owners over
 the   last 25  years.     Based  on   Federal
 investigations conducted in 1983, three removal
actions were  conducted.   In  1985,  the State
removed explosive materials.    In 1987, EPA
removed lab pack containers, drums of corrosive
and toxic materials, acid tanks, and compressed
gas cylinders.  In 1990, EPA removed fencing
around the slag area.  A 1990 ROD addressed
the  remaining  drums,  tanks,   transformers,
contaminated soil, baghouse dust, and chemical
and  tire piles.   This ROD addresses soil and
debris contamination in the slag area and in the
Southeast Park  as  OU2.   Future RODs will
address final remedies for soil, sediment, debris,
ground water,  surface  water, and air.   The
primary contaminants of concern affecting the
soil and debris  are VOCs including  benzene,
PCE, TCE, toluene, and xylenes; other organics
including PAHs, PCBs,  and  pesticides;  and
metals including arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and  transporting  approximately
160 cubic  yards of contaminated  soil  from two
areas  of  the Southeast  Park  to  an offsite
treatment and disposal facility; backfilling the
excavated area with clean soil and revegetating
the area;  conducting additional surface  and
subsurface sampling to confirm the  extent  of
contamination and  to  test  for exceedances  of
regulatory levels; excavating and treating slag
areas that are leaching contaminants using a
mobile  treatment unit  that stabilizes  the  slag
material;  conducting  a   treatability  test  to
determine  the  specific stabilization  process;
dewatering of any slag material found below the
water   table  during  excavation;  collecting,
treating, and  disposing  of extracted water;
returning treated slag to an area above the water
table; reprocessing or offsite disposal of any slag
material leaching contaminants above regulatory
levels;  excavating  and  offsite  disposal   of
localized areas of slag determined to interfere
with or be  unaffected by the  solidification/
stabilization  process;  offsite  treatment   and
disposal  of  slag  if  the  remedial  design
determines that  the volume of slag to be treated
is small compared to the current estimate of
                                             155

                                  September 30,1991
 SITE HISTORY/DESCRIPTION:

 The Sinclair Refinery site is a former refinery in
 Wellsville, Allegany County, New York. The site
 is composed of a 90-acre refinery area, 10-acre
 landfill area, and  14-acre offsite tank farm.
 Surrounding land use is primarily residential.
 The site borders the  Genesee River, which is
 used as a local source of drinking water supplied
 by the Village of Wellsville Municipal System.
 The underlying ground water flow at the site is
 generally  to the north and east, discharging
 directly into the Genesee River.  From 1901 to
 1958, the site was used to process Pennsylvania
 grade  crude oil  until a  fire  in 1958 halted
 operations.  Currently, some private companies
 and the State University of New York occupy the
 site. A 1981 site inspection revealed that debris
 from the eroding landfill area has washed  into
 and contaminated the  Genesee River. A 1985
 ROD addressed  operable  unit  1 (OU1)  and
 provided for:  removal and disposal of drums;
 excavation and consolidation of the south landfill
 area and filling of the excavated area with clean
 soil; partial channelization of the Genesee River
 to protect the landfill from erosion and flooding;
 capping of the consolidated landfill; construction
 of a fence around the entire landfill site; and an
 evaluation of the refinery portion of the  site.
 This ROD addresses OU2, remediation of the
 remaining contaminated areas at the site located
 within the 90-acre refinery area and  the offsite
 tank farm including the contaminated ground
 water  beneath the refinery.   Data  collected
 during the OU2 RI have not shown contaminant
 levels in landfill ground water to be in excess of
 Federal and State standards; therefore, EPA has
 chosen not  to  address landfill  ground water
 remediation under this OU2 ROD.  The primary
contaminants of concern affecting the soil  and
ground water are VOCs including benzene and
xylenes,  semi-volatile  compounds   including
naphthalene  and  nitrobenzene,   and metals
including arsenic and lead.
 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 excavating soil contaminated in excess of arsenic
 25 mg/1 and lead 1,000 mg/1 to a depth of 1
 foot;  treating excavated  soil  onsite prior to
 consolidation in the landfill; capping the landfill,
 and filling  and  revegetating excavated areas;
 conducting  long-term monitoring   of  biota,
 surface water, ground water, and soil-gas to
 track any potential contaminant migration from
 the  sub-surface  soil; onsite pumping and
 treatment  of contaminated   ground   water,
 followed by discharging  the treated ground
 water onsite to the Genesee River or offsite to
 the  POTW;  and  implementing  institutional
 controls in  the form of local zoning ordinances.
 This ROD also provides contingency  measures
 for ground water all or some  of which may be
 implemented based  on the  monitoring data
 colleted.  These measures include variations in
 pumping rates,  implementing engineering or
 institutional controls, monitoring specified wells,
 reevaluation  of   remedial  technologies, and
 invoking chemical-specific ARAR waivers. The
 estimated present worth cost  for this remedial
 action is $15,549,700, which includes an annual
 O&M cost of $750,183  for 30 years.

 PERFORMANCE STANDARDS OR GOALS:

 Chemical-specific goals for soil include arsenic
 25 mg/1 and lead  1,000 mg/1. Ground water
 will be treated to attain Federal MCLs or State
 standards.

INSTITUTIONAL CONTROLS:

Institutional controls  will  be  recommended
onsite in the form of local zoning ordinances.

                                 September 26,1991
SITE HISTORY/DESCRIPTION:

The 1.2-acre  South Jersey Clothing Company
(SJCC) site is an active clothing manufacturing
facility  located  in  Minolta,  Buena Borough,
Atlantic County, New Jersey.  Land use in the
area is  residential and commercial, and local
residents  obtain drinking  water from  the
Borough municipal water supply system, Onsite
features  include  two  buildings used  for
manufacturing operations, as well as the remains
of a building damaged in a 1979 fire.  Another
Superfund  site,  the  3,000-square-foot  Garden
State Cleaners (GSC) site, is  located 500 feet
south of the South Jersey Clothing site. GSC site
features include a small building covering much
of the site.  In 1940, SJCC began manufacturing
military clothing using VOCs including TCE, as
part of the dry cleaning process.  Based  on State
records, wastewater containing TCE from these
processes was routinely discharged  directly onto
the facility grounds,  and  other process wastes
were  stored  onsite  in  leaking drums.   In
addition, State records indicate that the 1979 fire
may have resulted in the release of an estimated
275 gallons of TCE from an onsite storage tank.
State investigations in 1981 identified elevated
TCE levels onsite. Later in 1981, SJCC identified
and removed thirty-three  55-gallon drums of
TCE-contaminated  soil;  installed  additional
ground  water monitoring  wells from  1981 to
1984; and installed a ground water pump and
treatment system under a State Order  in 1985.
In 1989, SJCC began installing a  limited soil
vapor extraction system in the  vicinity of the
TCE storage tank that reportedly ruptured in the
1979 fire, but this action was abandoned at the
start of the RL Because the SJCC and GSC sites
are in proximity to one another and have similar
contamination, both  sites  will be  remediated
concurrently.  This ROD addresses  soil and
ground  water contamination at both the SJCC
and GSC sites, as a final remedy. The primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, PCE,
TCE, and toluene.

SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
treating approximately  1,600 cubic yards of
onsite contaminated  soil using in-situ  vapor
extraction; treating the contaminated wastewater
from the vapor extraction processes onsite using
an air stripping column; treating air emissions
using carbon adsorption units;  pumping and
onsite treatment of contaminated ground water
using air stripping  and  carbon  adsorption,
followed  by  reinjecting  the  treated  water
upgradient from the  site; regenerating spent
activated carbon from both treatment processes
offsite;  conducting  long-term  ground  water
monitoring;  and  implementing   temporary
institutional  controls.   The estimated present
worth cost for this remedial action at the SJJC
site is $5,718,000, which includes an estimated
annual O&M cost of $293,100 for 70 years.  The
estimated present worth cost for this remedial
action at  both the  GSC  and SJCC sites is
$11,169,000, which includes an annual O&M cost
of $542,000.

PERFORMANCE STANDARDS OR GOALS:

Federal and State agencies have agreed to jointly
establish Interim Soil  Action  Level  (ISAL)
clean-up goals of 1,000 ug/kg for PCE and TCE,
given the predominance of the two compounds
at the site. Ground water remediation goals are
based on the more stringent of SDWA Federal
and State MCLs, and include PCE 1 ug/1 (State)
and TCE 1 ug/1 (State).

                                  September 27,1991
SITE HISTORY/DESCRIPTION:

The 2-acre Swope Oil & Chemical  site  is a
former   chemical  reclamation  facility   in
Pennsauken, Camden County, New Jersey. Land
use in the area is predominantly commercial and
industrial, and Pennsauken Creek lies 0.8 miles
northeast of  the  site.  The estimated 10,000
residents use ground water from a public supply
well screened in the lower  underlying aquifer
near the site as their drinking water supply. At
the time site operations ceased, pertinent site
features  included a  main  building,  distilling
house, diked tank farm, open drum storage area,
and  an unlined lagoon.  From 1965 to 1979,
Swope Oil & Chemical  used the site for the
reclamation  of chemicals.    Site  operations
included buying,  selling, manufacturing,  and
processing oils, chemicals,  and paints,  and
discharging  waste liquids  and  sludge to an
excavated,  unlined  lagoon.    Contaminated
material also was contained within a diked tank
farm and an exposed drum storage area.   In
1975, State investigations showed that discharge
of wastes to onsite drainage ditches had resulted
in  probable   migration   of   chemicals   to
Pennsauken Creek  via  storm  sewers.   The
owners were cited  for several disposal violations
in 1975, and  again  in  1979,  when the site
operations ceased.  Beginning  in 1984,  PRPs
removed drummed  wastes  and 3,000 tons  of
lagoon sludge, and also fenced the perimeter of
the site.  Later  in 1984, air  strippers  were
installed  on Municipal Well 1  by the water
commission  to  remove  VOC  contamination
detected in the aquifer. A 1985 ROD provided
for removal, offsite disposal, and treatment  of
storage tanks and  their contents; demolition  of
onsite buildings; and excavation and offsite
disposal of PCB-contaminated soil and  sludge
area material. This ROD addresses remediation
of subsurface  soil,  which continues  to leach
contaminants into  ground water, as  operable
unit 2.  Future actions will  evaluate whether
further source control measures or ground water
actions are necessary. The primary contaminants
of concern affecting the soil are VOCs including
PCE and  TCE, and other organics including
DEHP and naphthalene.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating onsite approximately 153,000 cubic yards
of contaminated unsaturated soil using  in-situ
vacuum extraction with potential enhancement
of biodegradation of soil contaminants, if  the
results of the treatability study  so  warrant;
treating air emissions using carbon adsorption or
thermal  destruction  prior   to  discharge,  if
necessary; and  monitoring  soil  and ground
water. The estimated present worth cost for this
remedial action is  $2,099,000, which  includes
estimated O&M costs of $397,500 for year 1 of
the vapor extraction system and $234,200 a year
for 5 years of ground water monitoring.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil clean-up goals are based
on New Jersey Interim Soil  Action Levels and
include 1 mg/kg for total VOCs and 10 mg/kg
for semi-volatiles, and  are designed to mitigate
the threat of ground water contamination.

                                September 30,1991
 SITE HISTORY/DESCRIPTION:

 The 14-acre Upper Deerfield Township Sanitary
 Landfill is an inactive landfill  located  on a
 27-acre  tract  of  land  in Upper  Deerfield
 Township,  Cumberland County, New Jersey.
 Land use in the area is primarily agricultural.
 The estimated  100 people  who live within one
 mile of the site  maintained individual  water
 supply wells until the early 1980's. From 1938 to
 1960, Seabrook Farms, Inc., a vegetable growing
 and processing company, operated the property
 as a gravel pit, and later as a waste disposal
 facility for  its  vegetative wastes.  During this
 time, pesticide residues  and containers  were
 allegedly disposed of at the site.  Since 1960,
 Upper  Deerfield Township has owned and
 operated the facility as a municipal sanitary
 landfill.   A  number  of  State  investigations
 identified   VOCs  including  vinyl  chloride,
 chlorinated solvents, and mercury in excess of
 Federal  Drinking Water Standards in ground
 water.   In 1983,  Upper  Deerfield  Township
began to supply affected residents with bottled
water,  and in 1986, the  township  installed a
public  water  supply  well and distribution
system.  This ROD addresses ground water and
air. Because EPA investigations showed that the
ground water and soil contamination associated
with the site no longer posed a health threat
under current or likely land use conditions, there
are no  contaminants of concern  affecting this
site.

SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
no further action since previous investigations
indicated  that  ground   water  and  soil
contamination associated with the site no longer
pose a health  threat under current or likely
future  land use  conditions.    However,  a
comprehensive ground water and air monitoring
program  will  be implemented,  which  will
include installing additional monitoring wells
and sampling downgradient residential wells. In
addition, sediment and surface water sampling
will be conducted.  The estimated present worth
cost for this remedial  action is $2,380,000, which
includes an annual O&M cost of $154,000.

                                     March  29,1991
 SITE HISTORY/DESCRIPTION:

 The 1.72-acre Waldick Aerospace Devices site is
 a former aerospace parts manufacturing facility
 in  Wall Township, Monmouth County,  New
 Jersey.  Land use in the area is predominantly
 commercial and industrial,  with  residential
 properties  located to the east.   Hannabrand
 Brook flows within 900 feet of the site before it
 merges with another stream that  eventually
 drains into the Atlantic Ocean. The site overlies
 a  sandy silt/sand  aquifer  system  that  is a
 potential source of drinking water.  From 1979 to
 1983, Waldick Aerospace Devices, Inc., used the
 site to manufacture electroplated  quick-release
 pins for the aerospace industry.  For at least the
 first 3 years of operation, wastewater containing
 metals and organic solvents was discharged
 directly onto the ground.   In  addition,  used
 machine oil  was  allowed  to  drain  out  of
 perforated drums onto the ground. As a result
 of  State and local  inspections, a number  of
 investigations were  conducted by EPA, which
 revealed VOCs, organics, and metals in soil and
 ground water in excess of MCLs.  In 1985, EPA
 conducted  a  removal  action  that  involved
 disposing of all manufacturing-related chemicals
 from the facility offsite.  A 1987 ROD provided
 a source control remedy for soil that included
 in-situ air stripping to remove VOCs, excavation
 and  offsite disposal  of  an area  of  metal-
 contaminated  soil,  and  decontamination  or
 demolition  of  onsite  buildings.   This ROD
addresses both a final  remedy for soil  as a
modification of the 1987 ROD, and an interim
remedial action  for  ground  water to prevent
further ground water contaminant  migration.
The modification to the 1987 source remedy is a
result  of  additional  investigations,  which
revealed   that  metals   were   widespread
throughout the site, and that the volume  of
contaminated soil was less  than half  of the
previously estimated amount.  In addition, tests
 during remedial design revealed that in-situ air
 stripping  was inappropriate  for the site.  A
 future ROD will address a final remedy for the
 ground water  contamination.   The  primary
 contaminants of concern affecting the  soil and
 ground water are VOCs  including PCE,  TCE,
 and  toluene;  other   organics;  and   metals
 including chromium and lead.

 SELECTED REMEDIAL ACTION:

 The selected modified  remedy for the source
 contamination at  this  site includes excavating
 8,000 cubic yards  of contaminated soil; using
 onsite thermal  treatment to remove organics;
 treating  inorganic  contaminated  soil  using
 solidification/stabilization, with backfilling or
 offsite disposal of the treated soil. The  selected
 interim  remedial  action  for ground  water
 includes installing four ground water extraction
 wells in  the zone  of  highest contaminant
 concentration; using chemical precipitation to
 remove  inorganics,  and   disposing  of  the
 resultant sludge offsite; using air stripping to
 remove organics;  reinjecting or infiltrating the
 treated  ground  water into  the aquifer, or
 discharging it to wetland areas to help offset any
 dewatering  effects caused  by ground  water
 extraction, if appropriate; and conducting ground

                                     June 27,1991
 SITE HISTORY/DESCRIPTION:

 The 13-acre Warwick  Landfill  is an  inactive
 municipal and industrial waste disposal site in
 the Town of Warwick, Orange County, New
 York.  Land use in the area is  predominantly
 residential, and the  site is surrounded  by
 woodlands and wetlands.  The estimated 3,000
 people  who  reside  approximately  1.5  miles
 northeast of the site  use residential wells as a
 source of drinking water.  From 1898  until  its
 closure  in 1978, the Warwick Landfill accepted
 municipal and  industrial  wastes  and sludge.
 Landfill contamination is attributed  to  the
 unpermitted  and  illegal  disposal   practices
 conducted by waste haulers and trespassers.  As
 a result of reports of illegal onsite dumping in
 1979, and an inspection after a property transfer
 in 1984, State investigations were conducted, and
 revealed soil,  sediment,  ground  water,  and
 surface water contamination throughout the site.
 This ROD addresses the contaminant source, the
 onsite landfill, and  provides an interim ground
 water remedy for the first operable unit (OU1).
 The final remedy for ground water (OU2) will be
 addressed in a subsequent ROD. The primary
 contaminants of concern affecting the soil, and
 ground water are VOCs including benzene, TCE,
 toluene, and xylenes; other organics including
 PAHs and phenols; and metals including arsenic,
 chromium, and lead.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
regrading the  landfill mound,  capping the
landfill with a  22-acre multi-layer cover, and
installing with a gas venting system; installing
and maintaining point-of-use treatment systems
consisting of granular activated carbon units at
contaminated residential  wells until a final
ground   water   remedy  can  be  evaluated;
sampling residential wells; monitoring ground
water and air; evaluating wetlands adjacent to
the property in an effort to mitigate potential
threats  from  the  site;  and  implementing
institutional controls including deed restrictions,
and site access restrictions such as fencing.  The
estimated present worth cost for this remedial
action is $14,279,600, which includes an annual
O&M cost of $526,300 for years 0-3 and $422,900
for years 4-30.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water clean-up goals
will be addressed in the final remedial action but
water at the point of use must meet Federal
MCLs.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prevent
disturbance of the cap.

                                  September 26,1991
 SITE HISTORY/DESCRIPTION:

 The 4.4-acre White Chemical site is a former
 chemical manufacturing facility in Newark, Essex
 County,  New Jersey.  Land use in the area is
 predominantly industrial and residential, with an
 estimated daytime population of 12,000 within
 one-quarter mile of  the site.  Onsite features
 include five major buildings and three smaller
 facility support buildings.   From 1983 to 1990,
 White Chemical Corporation (WCC) used the site
 to  manufacture  acid  chlorides  and  flame
 retardant compounds.  As a result  of State
 inspections, a number of  investigations were
 initiated  by the State and  EPA that identified
 10,900 55-gallon drums  containing improperly
 stored hazardous substances; 150 gas cylinders;
 126 storage tanks, vats, and process  reactors;
 12,000 laboratory-size containers; and  other
 miscellaneous hazardous material present onsite.
 In  1989, the  State  conducted  several  site
 investigations and issued notices of violation for
 improper management and storage of hazardous
 waste. In 1990, the State reinspected the site and
 again found various violations, and  ordered
 WCC to clean up the  site. As a result of WCC's
 failure to  respond  to  any  State notices or
 directives, the State initiated a removal action to
 stabilize  the site.  After removing 1,000 drums,
 the State exhausted  its  authorized funds and
 suspended  operations.  Shortly thereafter, the
 State requested that EPA consider conducting a
 removal  action at the site.   Later in 1990, EPA
 issued WCC a Unilateral Administrative Order
 (UAO) to  discontinue all  site activities and
 evacuate all  personnel.  EPA also performed
 several   site  assessments  and   initiated
 stabilization activities under removal authorities.
Ongoing actions include  drum overpacking,
 segregating   incompatible   substances,  and
restaging containers.    EPA  removed  an
additional 3,200 empty  55-gallon drums and
repaired  the  chain-link fence that secures the
property. The contents of many containers are
still unknown.  This ROD  addresses interim
remedial measures for surface contamination. A
future ROD will address additional remedial
measures deemed necessary as  a  result of a
comprehensive  RI/FS.     The  primary
contaminants of concern identified in the tanks,
drums, and  containers  are VOCs including
benzene and xylenes, other organics, inorganics,
and shock-sensitive compounds.

SELECTED REMEDIAL ACTION:

The selected  remedial  action for this interim
remedy includes continuing the site stabilization
process performed during the ongoing removal
action;   compiling   an   inventory,  staging
incompatible   substances, and  consolidating
compatible substances  for  onsite  temporary
storage; tranferring the contents of any container
of questionable integrity to  a new container;
overpacking  fuming  or  leaking  containers;
disposing of or recycling any empty containers,
along with any extremely hazardous substances
offsite to ensure the stability of the site; possibly
mobilizing a  treatment  system to  treat  or
neutralize  some  of  the  onsite  hazardous
substances;  decontaminating  empty   tanks,
reaction vessels, and process piping, followed by
onsite  storage; transporting  the  contaminated
material offsite to a RCRA-approved treatment
facility, to a hazardous waste disposal facility, or
to  an appropriate  facility  for  recycling  or
processing; developing an emergency response
contingency plan for   responding  to  any
emergencies that may occur during stabilization
efforts,  and possibly a  transportation  safety
contingency plan for transporting hazardous
substances; continuing  implementation of site
security  measures;  and   conducting
environmental   monitoring,   and  additional
investigations  to fully characterize  the  nature
and   extent   of  contamination  in   other
environmental  media at the site, and to evaluate
additional remedial measures. The estimated

                                     June 28,1991
SITE HISTORY/DESCRIPTION:

The 28-acre  AVCO  Lycoming-Williamsport
Division site is an active manufacturing facility
in  Williamsport, Pennsylvania.   Surrounding
land use  is  primarily residential.  The site
overlies a  surficial glacial aquifer and a deeper
bedrock aquifer that are used as seasonal sources
of drinking water.   Ground  water is pumped
from   the  Williamsport   Municipal   Water
Authority  (WMWA)  well field located 3,000 feet
south of the site.  Wetlands are located near the
site in  the 100-year floodplain of Lycoming
Creek and the Susquehanna River.  From 1929
until present, various manufacturing companies
including  a  bicycle and  sewing machine
manufacturing plant, a sandpaper plant, a tool
and die shop, a silk  plant, and aircraft engine
manufacturing plant  have been located onsite.
Possible sources of onsite contamination include
improper  waste disposal   in  a  "dry  well,"
laboratory chemical disposal  in a coolant well,
spillage and dumping in metal plating areas, a
sludge holding lagoon, cutting oils from a metal
chipster sump, degreasing  areas, and chemical
storage areas.     The  site  also  contains
approximately 40 underground  storage tanks
that are presently being abandoned or upgraded.
In 1984, the State identified VOC contamination
in the WMWA well  field.  In 1985, monitoring
and recovery wells  were installed onsite  and
offsite  to identify the source of contamination,
which was determined to be the AVCO plant. In
1986, the  State approved the AVCO remedial
action plan, which included installation of an air
stripping system to treat water from three onsite
and two offsite recovery wells, and discharge to
Lycoming  Creek.  This remedial action remains
in effect. Between 1989 and  1991, a RI/FS study
was conducted to further characterize the
contamination and source areas.   This  ROD
addresses  management   of  migration  of
contaminated ground water from the onsite area.
Remediation  of offsite  ground water will be
addressed in  a subsequent ROD.  The primary
contaminants of concern affecting the ground
water  are VOCs  including  TCE  and metals
including chromium.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
pumping and treatment of contaminated ground
water using  an onsite  treatment facility  that
utilizes precipitation,  coagulation, flocculation,
and air stripping; treating air stripper off-gases
using Best Available Technology (BAT), possibly
granular activated carbon or fume incineration;
dewatering and  offsite disposal  of  residual
precipitation  sludge and  spent carbon filters;
discharging treated water onsite to surface water;
monitoring ground water; and  implementing
institutional   controls  including   land   use
restrictions.  The estimated present worth  cost
for this remedial  action is $9,300,000, which
includes an annual O&M cost of $442,900 for 30
years.

PERFORMANCE STANDARDS OR GOALS:

Ground water clean-up  standards are based on
the more  stringent of Federal MCLs or non-zero
MCLGs, or background levels. Chemical-specific
goals were not provided.

INSTITUTIONAL CONTROLS:

Land use  restrictions will be implemented at the
site.

                                 September 30,1991
 SITE HISTORY/DESCRIPTION:

 The 30-acre Arrowhead Associates/Scovill site is
 a cosmetic-case manufacturing and filling facility
 in Westmoreland County, Virginia. Land use in
 the area  is predominantly  agricultural, with
 several businesses.   Also,  woodlands  and
 wetlands areas are located proximal to the site.
 There  is a  small  stream, Scales Branch, that
 originates onsite and flows to an offsite pond
 and creek.  The site overlies a shallow aquifer
 that is used by an estimated 500 people as a
 drinking water supply.  Ownership of the site
 has changed hands several times. From 1966 to
 1979,   Scovill,  Inc.,  and   later  Arrowhead
 Associates (AA), used the site for manufacturing
 cosmetic cases using electroplating, lacquering,
 and enameling processes.   Once the plating
 process  was  complete,  the  solutions  were
 discharged to onsite settling ponds. Supernatant
 from   these  ponds  was  either  reused  or
 discharged to surface water. Bottom wastes and
 small amounts of  other spent materials were
 stored in drums for subsequent offsite disposal.
 After   1979,  site   operations  switched  to
 cosmetic-case filling, and subsequently to wire
 harness manufacturing.    Currently,  Virginia
 Elastics uses the former plating area as a storage
 warehouse.  Numerous  investigations by the
 State  and EPA  revealed  extensive   soil  and
 ground water contamination. From 1986 to 1988,
 EPA conducted a two-phased removal action at
 the site. Phase I of the removal, conducted from
 1986 to 1987, included removal  of wastes and
 various contaminated materials.   Phase  II,
conducted from  1987 to 1988,  consisted of
treating and disposing of wastewaters, sludge,
and soil from  the  former settling ponds, and
offsite  disposal of contaminated soil  from a
drum  storage area.  In  1990, the ponds were
filled and graded, and erosion control measures
were installed.  This ROD addresses final
 remediation of soil and  ground water.  The
 primary contaminants of concern affecting the
 soil and  ground water  are  VOCs including
 benzene, PCE, TCE, toluene, and xylenes; and
 metals including chromium and lead.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 implementing  in-situ  vacuum  extraction  of
 VOC-contaminated soil; onsite  pumping and
 pretreatment  of contaminated ground water
 using pH adjustment, precipitation, flocculation/
 sedimentation,  and  filtration,  followed  by
 treatment  using  air  stripping  and  carbon
 adsorption, and onsite discharge of the treated
 water to Scales Branch; disposing  of residual
 sludge  and residues from the  ground water
 treatment process offsite; treating off-gases from
 the soil and ground  water treatment systems
 using carbon  adsorption; and  implementing
 environmental   monitoring, and institutional
 controls including ground water use restrictions.
 The estimated  present  worth  cost  for  this
 remedial action is $13,177,000, which  includes an
 annual O&M cost of $11,833,000.

 PERFORMANCE STANDARDS OR GOALS!

 Chemical-specific soil  clean-up goals will be
 determined  during   the   remedial   design.
 Chemical-specific ground water clean-up goals
 are based on SDWA MCLs and include benzene
 5 ug/1, PCE 5 ug/1, and TCE 5 ug/1.

 INSTITUTIONAL CONTROLS:

 Ground  water  use   restrictions   will   be
implemented to prevent the use of water from
 the contaminated aquifer until the aquifer has
been remediated to acceptable levels.

                                     March 29,1991
 SITE HISTORY/DESCRIPTION:

 The 12-acre Brodhead Creek site is a former coal
 gasification plant in the Borough of Stroudsburg,
 Monroe County, Pennsylvania. The site occupies
 the floodplain area at the confluence of Brodhead
 and McMichael Creeks. Surrounding land use is
 commercial and residential. Site features include
 two earthen levees  constructed to protect  a
 nearby sewage treatment plant from potential
 floodwaters.  From approximately 1888 to 1944,
 the coal gasification plant was operated along
 the west  bank of Brodhead  Creek.  These
 activities produced a liquid coal tar product
 comprised of PAHs, which was disposed of in
 an onsite open pit until the mid-194(ys. In 1980,
 during construction repairs  to the  toe of the
 flood  control  levee,  coal  tar  was  observed
 seeping into  Brodhead Creek.  From 1981  to
 1984,  several  state  and  federal  emergency
 response measures and  investigations were
 initiated onsite. These included installing filter
 fences and underflow dams to intercept coal tar
 seepage, installing a coal tar recovery pit on the
 bank  of Brodhead Creek, and constructing  a
 slurry wall to mitigate onsite coal tar migration
 toward Brodhead Creek. In addition, from 1982
 to 1983, the State and EPA conducted a program
 designed to  remove coal tar from a backwater
 channel area,  which involved  excavating and
 dewatering 900 cubic yards of sediment and
 backfilling the  area with clay and  clean soil.
 Also during this time period, the PRPs installed
 recovery wells  in the main coal tar pool and
 subsequently removed 8,000 gallons of coal tar.
This ROD addresses contaminated  subsurface
soil containing free coal tar, and provides an
interim remedy for the site.  A future ROD will
address onsite ground water contamination and
provide the final remedy for the subsurface soil.
The primary contaminants of concern affecting
the soil are VOCs  including benzene, toluene,
and xylenes; other organics including PAHs; and
metals including arsenic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
an in-situ innovative enhanced recovery process
which entails installing hot water injection and
extraction wells  in  the free  coal tar  areas
comprised of approximately 200 cubic yards of
subsurface  soil;  recovering both coal  tar and
process water from extraction wells; separating
the  coal  tar from  the process  water and
disposing of the  recovered coal tar at an offsite
permitted   incineration  facility;  treating  the
process water;  discharging a  portion of the
treated process water  to Brodhead  Creek, and
reinjecting the remainder of the treated  water
into the subsurface soil to  enhance coal tar
recovery; conducting  a treatability study  to
evaluate  the  coal   tar  recovery  process;
monitoring ground water, sediment, and  biota;
and implementing deed restrictions,  and site
access  restrictions  such  as  fencing.    The
estimated present worth cost for this remedial
action is $4,120,000, which includes a total O&M
cost of $1,112,000.

PERFORMANCE STANDARDS OR GOALS:

The enhanced recovery process will be applied
to the free coal tar (i.e., coal tar at 100% pore
volume saturation) areas, and will remove and
treat 60-70% of the free coal tar. This process will
prevent further leaching of contaminants into the
shallow ground water.

INSTITUTIONAL CONTROLS:

Deed restrictions will be enacted to limit future
site use.

 semi-rural,  with  a  woodland area  located
 northeast of the site, and an onsite stream west
 of the contaminated area.   Between 1970  and
 1982, chemical solvents were used at the facility
 at a rate of two to three 55-gallon drums per
 year.  During this time, a chemical spill occurred
 at Cryo-Chem, but cannot be definitely linked to
 the source of  contamination.   Well  sampling
 conducted  between 1985  and  1987 showed
 ground water contamination in monitoring and
 residential wells within 1 mile of the site, which
 led to  a  removal action  that required  the
 installation of activated carbon filter units in 20
 affected homes. EPA has divided the site  into
 three  operable units (OUs) for remediation. A
 1989  ROD addressed  OU1, the contaminated
 drinking water, by providing an alternate water
 supply.  A1990 ROD addressed the remediation
 of ground water using air stripping and carbon
 absorption  as OU2.    This  ROD   addresses
 contamination  in soil  caused  by past facility
 operations, which continues to leach from the
 soil into the ground water system.  The primary
 contaminants of concern affecting the soil are
 VOCs including TCA, TCE, DCA, and PCE.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
sampling the area to better define the extent of
the contamination; treating the contaminated soil
onsite using vapor extraction;  controlling air
emissions  using  carbon  absorption,  and
disposing of, or regenerating any spent carbon;
discharging any water captured during in-situ
vapor extraction to the pump and treat  system
currently  under  design;  and   conducting
confirmation soil  sampling and air monitoring.
The estimated  present  worth  cost  for  this
remedial action ranges from $53,500 to $66,400
based on the treatment selected. There are no
O&M costs associated with this remedial action.

PERFORMANCE STANDARDS OR GOALS:

Although current background contaminant levels
are  less  than  Federal   standards,  further
remediation  was deemed necessary to prevent
additional leaching of contaminants from the soil
to the ground water.  EPA intends to run the soil
vapor extraction system until it is effectively not
removing any additional VOCs. EPA does not
intend to continue remediation for OUS beyond
soil vapor extraction since it is known that the
contaminant  levels in soil will be below  levels
that are protective of human health.

                                    March 29,1991
 SITE HISTORY/DESCRIPTION:

 The 137-acre Delta Quarries/Stotler Landfill site
 includes a 57-acre former landfill, and is located
 between the City of Altona, Logan Township
 and the Village of Pinecroft, Antis Township,
 Pennsylvania.  Land use in the area is  rural.
 Several residences are approximately 35 feet east
 of the landfill boundary, and  wetlands  areas
 exist to the southeast and northeast.  Residences
 and businesses in the vicinity of the site rely on
 private wells adjacent to the landfill for  their
 drinking water supply.  Beginning in 1964, two
 adjacent municipal  landfills  were  operated
 onsite, and in 1976 these operations were merged
 into one landfill, known as the  Stotler Landfill.
 Delta Quarries and Disposal, Inc., purchased the
 landfill and continued to operate the facility until
 its closure in 1985. Reports from EPA, the State,
 and  previous landfill operators indicate that
 municipal wastes comprise 98% of the  total
 landfilled wastes;  however, the landfill  had
 accepted  some  industrial  wastes  including
 organic solvents, process sludge and metals from
 electroplating operation, tramp oils and residues
 from  sludge sedimentation basins, which have
 contaminated onsite soil and ground water in the
 landfill area.  In  1984, the State  and  Delta
 Quarries entered into a consent order to develop
 and implement a closure plan for the landfill. In
 1987,  the site owners  initiated the  plan by
 placing a 4-foot  soil cap  over the landfill,
 vegetating the area, and installing sedimentation
 controls including interceptor berms, channels,
and sedimentation basins.  All elements of the
 closure plan were completed except installation
of a gas venting system.  This ROD addresses
onsite ground  water  contamination.    The
primary contaminants of concern affecting the
ground water are VOCs including  PCE,  TCE,
and   vinyl chloride;  and  metals  including
manganese.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
pumping and onsite pretreatment  of  ground
water using  precipitation  to remove metals, if
necessary, followed by onsite treatment using air
stripping; discharging the treated water offsite to
Little Juniata River;  controlling air emissions
using activated carbon; monitoring ground water
and  surface  water;  maintaining the cap,  and
installing a  gas venting system;  conducting
periodic  site  reviews;  and   implementing
institutional  controls  including  deed and land
use restrictions, and site access restrictions such
as fencing. The estimated present worth cost for
this remedial action is $2,344,581, which includes
a present worth O&M cost of $1,176,989 over 30
years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific  ground   water   clean-up
standards are based on the more stringent of
SDWA MCLs or background levels, and include
U-DCA 5 ug/1  (MCL);  cis-l,2-DCE  70 ug/1
(MCL);  trans-l,2-DCE 100 ug/1  (MCL);
chloroform 100 ug/1 (MCL); PCE 5 ug/1 (MCL);
TCE 5 ug/1 (MCL); and vinyl  chloride 2 ug/1
(MCL).

INST1TUT1QNAL CONTROLS:

Land use restrictions will be implemented to
prevent future actions that would disturb the
landfill surface and wastes.   Deed  restrictions
will  provide notice  to  any future property
owners of potential hazards and  likewise restrict
the use of the property.

                                September 30,1991
SITE HISTORY/DESCRIPTION:

The 39-acre Dixie Caverns County Landfill is a
former municipal landfill  in Roanoke County,
Virginia. The surrounding land is rural, with the
nearest residence located 1/2 mile from the site.
The site is situated on a steep ridge between two
valleys  surrounded  by   heavily  forested
mountains traversed by small streams.  Two
unnamed headwater streams  receive surface
runoff  from  the site, and  discharge to the  the
Roanoke  River,  which  is  located  2  miles
south/southeast. The landfill is currently owned
and was operated by  the county of Roanoke
from 1965 until its  closure  in  1976.  During
operation, Dixie Caverns Landfill accepted an
estimated 440,000 cubic yards of municipal and
industrial wastes including refuse, scrap metal,
flyash, and sludge.  In  1983, EPA investigations
identified several  disposal areas  including a
discarded drum area, a sludge pit, and a large
flyash pile,  which contained elevated levels of
metals.  In  1987, EPA conducted a removal
action that addressed the drum and sludge areas;
however, removal of the flyash was suspended
upon  EPA's recommendation.   In 1987,  the
County developed  a removal  work  plan
proposing a proprietary stabilization process to
treat the flyash, and the plan was approved in
1988 with  remediation  levels set by  EPA.
Questions concerning the regulatory status of the
waste caused delay in  implementing the work
plan.    At  that  time,   EPA  recommended
suspension of further removal activity pertaining
to the flyash  because of uncertainty as  to
whether or not the County's plan would meet
Federal and State  requirements.   This  ROD
addresses the flyash at  the site as operable unit
1 (OU1).   Future  RODs will  address  other
remedial actions based  on RI/FS investigations.
The primary contaminants of concern affecting
the debris are metals including lead, cadmium,
and zinc.
SELECTED REMEDIAL ACTION:

The selected remedial action for this interim
remedy includes excavating and transporting
approximately 9,000 cubic yards of flyash offsite
to an EPA-approved High Temperature Metals
Recovery Technology facility for treatment and
subsequent reuse; and implementing State dust
and erosion and sediment controls during flyash
excavation.  The present worth cost for  the
remedial action is $3,927,158. There are no O&M
costs associated with this remedial action.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific flyash clean-up goals are based
on onsite  disposal criteria developed by EPA
during the recent K061 LDR ruling, and include
lead 0.095 mg/kg and cadmium 0.032 mg/kg.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 27-acre Dorney Road site is a landfill  in
Upper  Macungie Township,  Lehigh County,
Pennsylvania.     Land  use   immediately
surrounding the site is  rural, residential, and
agricultural. Approximately 7 acres of wetlands,
including ponded areas, are scattered throughout
the site, with the greatest concentration of these
areas in the north-central part of the site.  The
estimated 20 residents living within 1/4 mile of
the site use ground water as the primary source
of potable water.  Prior to 1959, the site was
used as an open pit iron mine.  From 1959  to
1979,  municipal and  industrial  wastes were
disposed of in the onsite abandoned iron mine
pit and  on  the surrounding land. In 1970, the
State requested that the landfill be compacted
and covered, but the owners failed  to comply.
State inspections during  1970 to 1972 identified
a variety of wastes disposed of at the landfill
including electric utility plant sludge, battery
casings, barrels  of petroleum products,  and
asbestos flooring waste.  The site was closed  in
1978 because the owners were unable to acquire
a landfill permit to renew disposal  operations.
In 1986, EPA performed an emergency removal
action to regrade a portion of the site to collect
and contain onsite surface run-off. Although a
soil cover was applied to portions of the site, the
landfill  was never graded and  capped,  and
onsite waste continues to be  exposed in areas.
Seepage of  leachate from landfill  wastes is the
principal source of ground water contamination.
A 1988 ROD addressed  operable unit 1 (OU1)
and provided for elimination of onsite ponded
water; regrading and multi-layer capping of the
site; installing  run-on/run-off controls; ground
water monitoring; and implementing
institutional controls including deed restrictions
and site access restrictions including perimeter
fencing. In 1991, EPA issued an Explanation of
Significant Differences (BSD) for OU1 requiring
mitigation of wetlands areas affected during cap
construction. This ROD addresses ground water
contamination  as OU2, and provides a final
remedy for the site.  The primary contaminants
of concern affecting the ground water are VOCs
including  benzene   and   TCE;  and   metals
including chromium and lead.

SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
providing wellhead  treatment  using  carbon
adsorption  for  the  private wells of affected
residences, and ground water monitoring.  The
estimated present worth cost for this remedial
action  is $274,040, which  includes an  annual
O&M cost of $14,410.

PERFORMANCE STANDARDS OR GOALS:

ARAR waivers will be issued for State standards,
specifically those requiring remediation of onsite
ground water   to  background  levels  and
remediation of offsite ground water to MCLs on
the basis  of  technical impracticability.   In
addition,  data  indicate  that  ground  water
contamination  appears   to   be   naturally
attenuating. Ground water action clean-up levels
are based on MCLs, risk levels, and State
standards, and  include benzene 5  ug/1, TCE
5 ug/1, chromium 100 ug/1, and lead 15  ug/1.

                                     March  29,1991
SITE HISTORY/DESCRIPTION:

The 25-acre Eastern Diversified Metals (EDM)
site  is a former metals reclamation facility in
Rush   Township,   Schuylkill   County,
Pennsylvania.    Land  use  in  the  area is
predominantly agricultural with small pockets of
residential, commercial, and undeveloped land.
In addition, a small westward moving stream
traverses  the  site's   southern  border  and
discharges into the  Little Schuylkill  River,
250 feet west of the site.  Before 1966, the site
was owned by an aluminum manufacturing
facility.  From 1966 to 1977,  EDM reclaimed
copper and aluminum from metal wire and cable
in  an  onsite  processing  building.   Plastic
insulation surrounding the metal wire and cable
was mechanically stripped and separated,  and
the waste insulation was disposed of behind the
processing facility.  Over time, the insulation
material formed a residual pile of "plastic fluff,"
the most distinctive site  feature.  In 1974, the
State required  EDM  to  install  a  leachate
collection  and  treatment  system  onsite  to
monitor, collect, and treat leachate  emanating
from the fluff pile.   Because of  high BOD
concentrations  in  the leachate, a  secondary
treatment was designed and installed, channeling
leachate using drainage ditches and collection
trenches through an equalization lagoon to an
onsite treatment plant.  In 1977, EDM terminated
operations, and in 1979  and 1980, residents
complained of odors from the site and expressed
health  concerns.   Subsequent State and EPA
investigations from 1983 to 1985 determined that
the  fluff  piles,  soil,  sediment, leachate,  and
ground water were contaminated by VOCs, other
organics, and metals.  This ROD addresses  two
of three operable units (OUs) at the EDM site.
This ROD provides a final remedy for "hot spot"
fluff and soil areas, metal-contaminated sediment
and soil, and miscellaneous debris as OU1;  and
provides an interim remedy for contaminated
ground water  as  OU2.   Future  RODs  will
address the final selected actions  for ground
water (OU2), and the remainder of the fluff pile
(OU3).  The primary contaminants of concern
affecting the  soil,  sediment,  debris, ground
water, and surface water are VOCs  including
TCE; other organics including dioxins and PCBs;
and metals including lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
removing 480 cubic  yards of soil contaminated
with  lead  above Federal target levels  from
drainage ditches; excavating and incinerating,
either  onsite or  offsite,  500 cubic  yards of
dioxin-contaminated fluff and 5,160 cubic yards
of PCB-contammated fluff and soil in excess of
Federal target levels; consolidating the  onsite
scattered fluff with  the remainder  of the fluff
pile; removing 120 cubic yards of sand/silt/clay
stream sediment contaminated by metals above
Federal target levels; conducting toxicity testing
on incinerator residuals, miscellaneous debris,
and possibly on soil and sediment depending on
type of disposal or containment; disposing of
incinerator  residuals in an  offsite municipal
landfill or consolidating these with the remaining
fluff pile onsite, if residuals pass the toxicity test;
if  residuals fail the  toxicity test, treating with
stabilization prior to disposal; disposing of onsite
soil and/or sediment passing the EP toxicity test
in an offsite municipal landfill; or if soil and
sediment fail an EP toxicity test, stabilizing prior
to disposal; disposing of miscellaneous debris
passing the toxicity test in an offsite municipal
landfill; or if miscellaneous  debris  fails the
toxicity  test, disposing of these materials in an
appropriate RCRA unit; upgrading surface water
run-on/run-off  controls;  installing  a ground
water collection trench  parallel  to the existing
trench to relieve overburden ground water flow;
treating ground water and leachate at an onsite

                                     June 28,1991
SITE HISTORY/DESCRIPTION:

The 4-acre First Piedmont Quarry 719 site is an
inactive  industrial  and  agricultural  landfill
located  north  of  the  city of  Danville  in
Pittsylvania County, Virginia. Land in the area
consists of open space  and  woodlands, with
residential  areas located  to  the south.  The
estimated 1,893 people living within 2 miles of
the site obtain drinking water from wells or
springs. Two small ponds and a wetlands area
are located  onsite. In addition, the landfill is a
ground water discharge  area for an underlying
aquifer  draining  through  the  wetlands  to
Lawless Creek, which runs 1,400 feet northwest
of the quarry.  The site originally operated as a
quarry for crushed stone.  From 1970 to 1972,
industrial and agricultural wastes were landfilled
in the 2-acre quarry area  of the site.  Wastes
include hundreds of buried drums; tires; scrap
rubber;  approximately  15,000  gallons  of  a
mixture of MS-20 (a floor degreaser containing
PCE^  water,  carbon  black,  and  detergent;
off-specification batch materials containing trace
amounts of lead oxide; soil; tobacco scraps; and
wood.   The  landfill contains approximately
65,000 cubic yards of industrial and agricultural
wastes and  3,000 cubic yards of  soil.  Two
additional waste areas,  the Carbon Black Pile
awi the Waste Pile, have been identified onsite
near the western edge  of the landfill.   The
Carbon Black Pile contains 100 cubic yards of a
tire reinforcement additive and  contaminated
soil, and the Waste Pile contains 10 cubic yards
of steel  and nylon  cords, glass, waste rubber
strips, and contaminated soil.  In 1972, the State
ordered waste  disposal operations to cease as a
result of a  fire  on  the landfill.  This ROD
provides a  final remedy for all  site  media
including  the  landfill material,  leachate, the
Carbon  Black  Pile  and Waste Pile, and the
contaminated  Northern  Drainage  soil  and
sediment. The  contaminants of concern affecting
the site  are  metals  including  arsenic, lead,
barium, antimony, and zinc.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and disposing offsite 1,080 tons of
waste from the Carbon Black and Waste Piles
along with  the contaminated soil and sediment
from the Northern drainage areas; performing a
TCLP of excavated material to determine if it is
RCRA characteristic waste, and if so, solidifying
and stabilizing the excavated material prior to
offsite disposal;  filling the excavated Carbon
Black and  Waste Pile areas with clean soil;
disposing of 30-40 drums from the surface of the
landfill at a RCRA Subtitle C treatment facility;
decontaminating and disposing of surface debris
at an approved landfill; constructing a RCRA-cap
and an associated leachate collection system over
the 2-acre landfill area; covering the cap with
6 inches of  soil and contouring soil to promote
run-off, and revegetating the area; constructing
run-off control berms in the Northern Drainage
areas to lessen landfill cap run-oŁfs; pretreating
leachate, if necessary, prior to transporting to a
POTW, or constructing  an  onsite   treatment
system with onsite discharge to surface water if
the POTW will not accept the leachate; draining
the north and south ponds, and transporting and
discharging pond  water offsite to  a POTW;
monitoring  ground   water   and  conducting
bioassays  to  assess  the  effectiveness  of the
removal of the Carbon Black Pile and Waste Pile
on the reduction of contaminant  levels in the
Southern   Drainage;  and   implementing
institutional controls including deed restrictions,
and site access restrictions such as fencing. The
estimated present worth cost for this remedial
action is $2,154,000, which includes  an  annual
O&M cost of $66,200.

                                 December 31,1990
SITE HISTORY/DESCRIPTION:

The 5-acre Greenwood Chemical site is a former
chemical  manufacturing facility in Newtown,
Albemarle County, Virginia.  Land use in the
area is  mixed  residential and  agricultural.
Onsite features include several buildings, storage
sheds, a buried drum area, and seven former
treatment  lagoons.  All residents  who reside
within   3  miles  of  the site  are  completely
dependent on the ground water underlying the
site for their drinking water supply.  From the
1950's  to  1985,  either Cockerille  Chemical
Company  or Greenwood Chemical Company
used the site for manufacturing chemicals for
industrial,  agricultural,  pharmaceutical,  and
photographic purposes. The companies stored,
treated,  and disposed of chemicals onsite.  In
1985, operations ceased at the facility  following
an explosion and fire. EPA investigations that
were conducted after this fire identified elevated
levels of cyanide, SVOCs, and VOCs in lagoons
and  ground water.  In 1987,  EPA  removed
buried  and  surface drums  and containers of
chemicals from the site, along with the sludge
associated with three of the onsite  lagoons.  A
1989 ROD provided  for offsite  incineration,
solidification and/or disposal  of  4,500 cubic
yards of contaminated soil, and  removal of
containerized chemicals.   An  explanation of
significant differences issued in 1991 authorized
the removal of three process buildings.  This
ROD addresses the contaminated ground water
and surface water as operable umt 2 (OU2) and
provides an interim remedy. A future ROD will
address  additional contamination of onsite soil.
The primary contaminants of concern affecting
the ground water and surface water are VOCs
including  benzene, PCE,  TCE, and  toluene;
SVOCs  including  naphthalene;  and  metals
including arsenic.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
onsite pumping and treatment of contaminated
ground and surface water using a treatment
system consisting of precipitation, sedimentation,
filtration,  and  UV/oxidation,   followed  by
discharging the treated water onsite to surface
water; treating onsite sludge residuals from the
ground water  treatment process, if necessary,
prior  to  offsite  disposal  in a  landfill; and
monitoring ground and  surface water.   The
estimated present worth cost  for this remedial
action is $3,218,000, which includes an estimated
O&M cost of $1,419,000 for 5 years.

                                     June 28,1991
SITE HISTORY/DESCRIPTION:

The 14-acre Halby Chemical site encompasses a
chemical  storage  facility   and  associated
warehouses in Wilmington, New Castle County,
Delaware.  Land  use  in the area is primarily
industrial.  Storm water run-off from the site
generally flows toward a drainage ditch which
discharges into the Christina River.  From 1948
to 1977, the Halby Chemical Plant process plant
area was used  to produce  sulfur  compounds,
and until 1969, a portion of the site was used to
store arsenic-containing pyrite ore. From 1948 to
1964, the plant discharged  all liquids into an
adjacent marsh or lagoon, which drained into the
Lobdell Canal before emptying into the Christina
River,   From 1964 to 1975,  the  plant acid
wastewater was discharged to the public sewers.
From 1975 to  1977,  the  owners  periodically
diverted the  acid wastewater flow from the
county sewer system to its pilot plant, and the
treated wastewater was discharged to the lagoon.
In July of 1977, the facility was issued a NPDES
permit to discharge cooling water and effluent
from the process  plant treatment plant.  The
plant then closed in August 1977. Since 1977,
Brandywine Chemical  Company has used the
site to receive and distribute bulk chemicals.  As
a  result of  citizen  complaints  about lagoon
overflow,  hydrogen  sulfide-like  odors,  and
numerous spills, a number of investigations were
conducted by the  State and EPA  beginning in
1983, which identified leaking drums and stained
soil. Analyses of samples taken during this site
investigation revealed  VOCs, organics, metals,
and other carcinogenic compounds in the soil.
This ROD addresses the first of two operable
units (OUs) and provides a final remedy for soil
and debris in  the process plant area.
Contamination of air, surface water,  ground
water, and sediment in the marsh and lagoon
areas will be addressed in a subsequent ROD as
OU2,  The  primary contaminants of concern
affecting the soil and debris are VOCs including
benzene,  TCE,  toluene,  and  xylenes; other
organics including PAHs; and metals including
arsenic,  chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
consolidating debris onsite or disposing of all
debris offsite; excavating and stabilizing the top
6 inches of approximately 10,300 cubic yards of
contaminated surface soil in  the process plant
area, followed by replacing the stabilized  soil
onsite; capping the approximately 5,800 square
yards residuals  area  with  an  asphalt  cap;
conducting soil monitoring; and implementing
institutional controls including deed restrictions.
The  estimated  present  worth cost  for  this
remedial action is $1,586,000, which includes an
annual O&M cost of $43,000.

PERFORMANCE STANDARDS OR GOALS:

The  clean-up goals  for  soil  contaminants
including arsenic and carcinogenic PAHs are set
at background levels.  Additional sampling and
analysis is required to  ascertain background
levels; however, approximate goals include
arsenic 10 mg/kg  and  carcinogenic
PAHs 1.2 mg/kg.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prevent
post-closure use of the property  and possible
damage  to the cap.

                                 September 30,1991
 SITE HISTORY/DESCRIPTION;

 The 12- to 15-acre Haver town PCP site consists
 of  a former wood treatment facility and an
 adjacent  industrial   facility  in  Haverford
 Township,   Delaware  County, Pennsylvania.
 Land use in the area is mixed residential and
 industrial. Naylors Run, a creek that drains the
 entire site, flows into Cobbs Creek, which joins
 Darby Creek before entering the Delaware River.
 Only three families who reside more  than one
 mile from the site use the ground water as their
 drinking water supply.  From 1947 to 1991,
 National Wood Preservers (NWP) used the site
 for treating wood.  Treated wood was air dried
 on  drip racks in dirt  areas around the site and
 stored in a dirt-covered storage yard. Chemicals
 were stored in several tanks adjacent  to  the
 facility.   It  has been estimated  that  up  to
 1 million gallons of spent wood preservatives
 were dumped into a nearby drip well. This
 disposal practice is believed  to be a primary
 source of contamination to ground  water and,
 ultimately, Naylors Run.   From 1962 through
 1989,  the   State  conducted  a number   of
 investigations, which  revealed PCP, oils, PAHs,
 dioxin,  heavy metals, VOCs, and phenols  in
 ground  and surface  water.   In 1976, EPA
 initiated a   response  action,  which  included
 ground water pumping and treatment, installing
 filter fences, sealing a sanitary sewer, and an
 attempt  to  grout two  sewer pipes  which
discharged   into  Naylors Run.   Currently,
contaminated ground water still discharges into
Naylors Run from a storm sewer pipe. A 1989
ROD addressed operable unit 1  (OU1), the
cleanup of wastes staged  onsite from  previous
investigative actions,  and  the interim  remedial
measure of designing and installing an oil/water
separator at the storm drain outlet along Naylors
Run. This ROD addresses an interim remedy for
shallow ground water contamination, as OU2. A
subsequent   ROD  will  address   sediment
contamination   in  Naylors   Run,   soil
contamination onsite,  potential deep ground
water  contamination  from  onsite  soil,  and
surface water and sediment contamination due
to run-off from onsite soil, as OU3.  The primary
contaminants of concern affecting the ground
water  are  VOCs  including  benzene,  TCE,
toluene, and xylenes; other organics including
dioxin, oils, PAHs, PCP, and phenols; and metals
including arsenic.

SELECTED REMEDIAL ACTION:

The  selected remedial action for  this interim
remedy includes installing two  free product
recovery  wells  with   floating free  product
skimmers onsite; installing a shallow ground
water collection drain and pumping station, as
well as additional ground water wells to monitor
shallow ground water; rehabilitating the existing
storm sewer to reduce infiltration by lining the
sewer, followed by directing all shallow ground
water  collected   to the  existing  oil/water
separator; constructing an onsite ground water
treatment plant,  which  will include  chemical
precipitation to remove  inorganic  compounds,
with  either  a  powdered  activated carbon
treatment (PACT)  system  or  an  advanced
oxidation process (AOP), and granular  activated
carbon treatment as a  reinforcement for  the
PACT or AOP to remove organics and destroy
dioxins; treating effluent  from the  oil/water
separator  using  the  new  treatment  plant;
discharging the effluent from the treatment plant
onsite to surface water; treating and disposing of
any  residuals   offsite;  and  ground  water
monitoring.  The estimated present worth  cost
for this remedial  action ranges from $10,036,000
to $12,177,000, which includes an annual O&M
cost  ranging from  $485,500  to  $595,000  for
30 years.

                                September 30,1991
SITE HISTORY/DESCRIPTION:

The 20-acre Hebelka Auto Salvage Yard site is an
automobile junkyard in Weisenberg Township,
Lehigh County, Pennsylvania. Land use in the
area is predominantly agricultural, with  four
residential properties close to the site. The site
is located within the headwaters of the Iron Run
subdrainage basin. From 1958 to 1979, and again
from 1989 to present, the site was used as an
automobile junkyard and for salvage operations.
Scrap iron was recovered from used  storage
tanks that were disposed onsite,  some of which
still contained  organic chemicals.  In addition,
during the past 10 to  15 years,  approximately
1,000 cubic yards of used battery casings have
been disposed of onsite in two piles, along with
empty  storage tanks and drums, junked cars,
and miscellaneous scrap metal.  In 1985, EPA
investigations identified elevated levels of lead
and chromium in soil and sediment.  A 1989
ROD addressed remediation  of site areas with
lead concentrations exceeding 560 mg/kg in soil,
as well as the piles  of scrap battery  casings
above these soil areas.  The ROD also provided
for removal and recycling of the battery casings,
and excavation and  treatment  of soil using
cement- or lime-based  fixation processes.  This
ROD was developed to address  soil outside of
the high lead concentration areas, ground water,
surface water, and air. However, because site
investigations  have  found  no  evidence of
contamination  in the  media  addressed in this
ROD, there are no contaminants of concern.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
no further action other than monitoring ground
water and surface water of Iron Run annually,
and a bioassessment of the creek. The estimated
present worth cost  for this remedial action is
$66,300, which includes an annual O&M cost of
$4,500 for 30 years.  The cost for the follow-up
bioassessment is $125,000.

                                September 30,1991
SITE HISTORY/DESCRIPTION:

The 25-acre Heleva Landfill  site is a former
sanitary landfill in North Whitehall Township,
Lehigh County, Pennsylvania.  Land use in the
area  is predominantly rural with  scattered
residences.  The estimated 150 people who reside
within one-quarter mile of the  site used  the
ground water underlying the  site  as  their
drinking water supply prior to 1986. From 1967
to 1981, the Heleva Landfill accepted municipal
and industrial wastes,  which included  large
volumes of  liquid TCE.  As a result of Heleva's
denied requests for solid waste permits and
refusal   to  implement   a   State-ordered
biostimulation  project,  the  State closed  the
landfill in 1981. A number of subsequent State
investigations  revealed   ground   water
contamination  by  VOCs,  other organics, and
DNAPLs at levels  that exceeded State  and
Federal ground water  limits.  A 1985  ROD
addressed onsite ground water contamination
and provided for extending  an existing water
main;  capping the entire landfill; constructing
surface  water diversions  and  gas  venting
systems; constructing an onsite ground water
treatment facility; establishing a pumping and
treating  system   for   the   contaminated
neargradient ground water; and ground water
sampling and monitoring. Construction of all of
these   major  remedial activities  has  been
completed except for the ground water extraction
and treatment  component.  This ROD amends
the ground water component based on data from
the 1989 predesign study which determined that
collection of downgradient  ground  water is
technically feasible.  The primary contaminants
of concern affecting the ground water are VOCs
including benzene,  PCE,  TCE,  toluene,  and
xylenes.

SELECTED REMEDIAL ACTION:

The amended remedial action  for  this  site
includes continuing with the selected remedy
from the previous ROD but replacing the ground
water portion of the remedy with extraction of
neargradient ground water to contain the highly
contamination dissolved plume in the vicinity of
DNAPL contamination in the ground  water;
pumping  and   onsite  treatment  of  the
downgradient  portion of  the aquifer,  and
discharging the treated ground water  onsite to
surface water. The estimated present worth cost
for this amended remedial action is $40,950,000,
which  includes  an  annual  O&M  cost  of
$1,848,000 for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Downgradient ground water will be remediated
to State background levels including benzene
0.2 ug/1, PCE 0.03 ug/1,  TCE 0.03 ug/1, and
toluene 0.2 ug/1. The State and Federal ARARs
for remediation of neargradient ground water to
background levels and MCLs will be waived due
to technical impracticability.

                                September 30,1991
SITE HISTORY/DESCRIPTION:

The 8.64-acre Hellertown Manufacturing site is
an inactive spark plug manufacturing facility in
Northampton  County,   Pennsylvania,
approximately  1.5 miles south of Bethlehem.
The  site  is  bordered  by   commercial  and
residential   areas,   highway  and   railroad
transportation corridors, Saucon Creek, and a
wetlands area.    Onsite features  include a
124,000-square-foot building,  and five lagoons
totaling 500,000 cubic feet. From 1930 to 1975,
chemical  wastes  including TCE, zinc  plating
waste, chrome dip waste, cleaners, and cutting
oils generated during  plating and degreasing
processes were disposed of onsite in the unlined
lagoons. Waste from these activities then seeped
into the local soil and rock strata. In 1976, after
the facility began discharging treated wastewater
into the municipal sewer system, the lagoons
were backfilled, closed in place, and  covered
with topsoil. The material used to backfill the
lagoons  included   rejected   spark   plugs,
demolition material from road-building activities,
and soil excavated during construction of the
nearby Bethlehem wastewater treatment plant.
Studies  conducted   in   1990   identified
contamination by VOCs, metals, and organic
compounds in lagoon backfill, soil, and in onsite
ground water.   The primary contaminants of
concern affecting the soil and ground water are
VOCs including benzene, DCE, PCE, TCE, vinyl
chloride, and xylenes; other organics including
PAHs; and metals including chromium.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
capping the former 3.5-acre lagoon area with an
impermeable asphalt and clay cover; pumping
and onsite treatment of ground water using air
stripping; removing solids using a settling tank
or clarifier followed by filtration; discharging the
treated  effluent  onsite  to  Saucon  Creek;
long-term ground water monitoring; controlling
surface  water  run-off;   and  implementing
institutional controls including deed restrictions.
The  estimated  present worth  cost  for  this
remedial action is $2,250,000.

PERFORMANCE STANDARDS OR GOALS:

Ground water clean-up  goals  are  based on
SDWA  MCLs  or  State  background
concentrations, whichever is the more stringent.
Chemical-specific ground water clean-up levels
include benzene 0.2 ug/1 (State  background),
PCE  0.03 ug/! (State  background),
TCE 0.12 ug/1 (State  background), and  vinyl
chloride 0.18 ug/1 (State background).

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prohibit
excavation of contaminated soil and the use of
onsite ground water for domestic purposes.

                                    March 29,1991
SITE HISTORY/DESCRIPTION:

The  30-acre Industrial  Drive site  is an active
sanitary  landfill  and   industrial  facility  in
Williams  Township,   Northampton  County,
Pennsylvania. Land use in the area is industrial,
residential, and agricultural.  The  site contains
active and inactive sanitary landfills as well as
active,  inactive,  and   abandoned  industrial
facilities.  The Lehigh River and Lehigh Canal
are located northwest of the site, and a portion
of the site rests upon the trace of a thrust plane
known  as  the Musconetcong  Fault.   These
conditions  have created a complex  geologic
setting in which ground water flow is governed
by topography.  Prior to 1961, the site was used
for iron ore mining, industrial  activities, and
agricultural purposes. In 1961, sanitary landfill
operations began onsite, and the site  accepted
municipal solid waste for disposal in an unlined
landfill. By 1980, the landfill had expanded to 30
acres.  In the late 1970's, local residents alleged
that  the now  inactive unlined landfill  had
accepted   hazardous    wastes   that   had
contaminated local drinking water wells.  Waste
disposal in the unlined  landfill ceased in 1986,
but  closure  of the landfill  has not  been
completed.  In 1986, the  State issued a permit for
a  10-acre  expansion  of the landfill,  which
included a liner and leachate collection system.
This  expansion  landfill  is currently active, but
there are no plans to further expand the landfill
area. Contamination in local ground water wells
was first detected in 1983. Subsequently, the site
has been divided into two operable units (OUs)
for remediation.  A 1986 ROD addressed OU1,
and provided for an alternate water supply by
connecting  numerous private well users to an
existing municipal  water supply.   This ROD
addresses QU2,  the contaminated ground water
and the low-level threat caused by the unlined
municipal landfill. The primary contaminants of
 concern affecting the soil, debris, and ground
 water are VOCs including benzene, PCE, and
 TCE; other organics;  and  metals including
 chromium and lead.

 SELECTED REMEDIAL ACTION;

 The selected remedial action for this site includes
 closing  and capping the unlined landfill area
 with a clay or synthetic cap; onsite pumping and
 treatment of contaminated ground water using
 an air stripper, followed by carbon adsorption
 with  onsite discharge  of  the treated ground
 water to the Lehigh River; regenerating spent
 carbon offsite; and long-term monitoring of the
 closed landfill and ground water.  If the selected
 remedy cannot  meet the specified remediation
 goals,   a  contingency   remedy  will  be
 implemented to prevent further migration of the
"plume,  which will include a combination  of
 containment  technologies  including  ground
 water extraction and treatment, and institutional
 controls. The estimated present worth cost for
 this remedial  action  is  $12,775,000,  which
 includes an annual O&M cost of $536,000 for
 years 0-1 and $498,000 for years 2-45. There will
 be an additional O&M cost  of $20,000 every
 5 years.

 PERFORMANCE STANDARDS OR GOALS:

 The goal of this remedial action is to remediate
 ground  water to background levels as specified
 by the  State Hazardous Waste Management
 Regulations.  Chemical-specific goals include
 benzene 0.2 ug/1, PCE 0.03 ug/1, TCE 0.03 ug/1,
 chromium 50 ug/1, and lead 5 ug/1.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 9-acre McAdoo Associates site is an inactive
strip and deep mining facility located in Kline
Township, Schuylkill County, Pennsylvania. The
site  consists of  two  locations:   the  8-acre
McAdoo-Kline Township  (MKT) location,  and
the 1-acre McAdoo-Blaine Street (MBS) location.
The MKT location is situated at the site of an old
(subsurface and surface strip) coal mine,  and
land adjacent to this  location is industrial,
abandoned, or contains reclaimed  mine areas.
The shallow aquifer at the MKT location consists
of ground water-filled mine workings and other
subsurface voids  beneath the MKT location,
collectively called the "mine pool."  The mine
pool discharges at the Silverbrook discharge to
the upper reaches of the Little Schuylkill River.
Both the mine pool and  the river have been
severely affected by acid  mine drainage.  The
MBS location is adjacent to a residential area and
a mine spoil reclamation site, and is presently
covered with gravel and used for vehicle storage.
From the 1880's to the 1960's, strip and deep
mining of anthracite coal occurred at the MKT
location.   Two rotary  kiln furnaces and an
upright liquid waste incinerator were installed
onsite between 1975 and 1976 to reclaim metals
from waste  sludges, reportedly  using waste
solvents as fuels.  In 1979, EPA ordered the MKT
location  to  close  because  of   numerous
environmental compliance problems.  At the
time of closure,  the  location contained  an
incinerator, a garage and offsite  trailer, 6,790
drums  of hazardous waste,  four above-ground
15,000-gallon storage tanks, three above-ground
10,000-gallon  tanks, and miscellaneous debris.
The MBS location was used for the storage of
waste  oil   and  hazardous  waste  in  five
underground tanks.  Activities at the MBS
location were stopped by EPA in 1979.  As a
result of Federal investigations, all drums and
site  features  were removed  from the  MKT
location between 1981 and 1988.  A 1984 Initial
Remedial Measure (IRM) for the MBS location
provided for removal of underground tanks and
contaminated  soil, and a 1985 ROD addressed
remediation of soil contamination at the MKT
location. This ROD addresses sediment, ground
water, and surface water at the MKT location,
and ground water at the MBS location. EPA has
determined that no further remedial action other
than that already implemented  at the  site  is
required to ensure protection of human health
and  the environment; therefore, there  are  no
contaminants of concern.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site is no
further action because previous interim remedial
activities were adequate to protect human health
and the environment. Ground water monitoring
at the  MKT  and  MBS  locations will  be
performed,  including  expanding the ongoing
water quality  monitoring program at the MKT
location,  and  installing four  ground  water
monitoring  wells at  the MBS location.   The
estimated present worth cost for this no action
remedy  with  ground water  monitoring  is
$503,540, which includes a present worth O&M
cost of $434,000 for 30 years.

                                 December 31,1990
SITE HISTORY/DESCRIPTION:

The 3-acre  Mid-Atlantic  Wood  Preservers
(MAWP) site is a wood treatment facility in
Harmans, Anne Arundel  County, Maryland.
Land use in the area is predominantly industrial
and residential, and a wetland area traversed by
Stony Run Creek lies 600 feet west of the site.
Since 1974, the  facility  has been  used  for
pressure treatment of lumber using chromate
copper arsenate (CCA) as the wood preservative.
The site is divided into two areas: a Treatment
Yard on the eastern half of the site, and Storage
Yard on the western half. The Treatment Yard
contains CCA storage tanks, a pressure cylinder,
and a  drip pad area.  In  1978, the county
determined that  water in a  shallow residential
well downgradient of the site was  contaminated
with  high  levels  of hexavalent chromium.
Subsequent investigations by the  State in 1978
revealed  that  soil   and   ground   water
contamination by chromium and arsenic was the
result of an overflow pipe from a  CCA storage
tank.   Under  an agreement  with the State,
MAWP removed 26 cubic yards of contaminated
soil beneath the overflow  pipe,  modified the
CCA storage system, and installed a concrete
drainage pad to collect drippings and reduce
future   contamination.     However,   offsite
investigations by EPA in 1983 identified elevated
levels of arsenic and chromium in ground water.
Further EPA and MAWP studies documented
that onsite arsenic-contaminated soil, the result
of removing treated wood prematurely from the
drip area before it had dried, was the principal
threat.   In addition, these studies  identified
approximately  5,200 cubic  yards  of  degraded
soil, to  an average  depth  of 2  feet, in the
Treatment Yard drip pad area and in the western
most third  of  the Storage Yard.   Residential
ground water metal  contamination levels were
found to be at much lower levels than detected
in earlier investigations; arsenic was not
detected, and chromium was detected above the
MCL in  only one well.  This ROD  addresses
contaminated onsite soil and ground water.  The
primary contaminants of concern affecting the
soil  and ground  water  are  metals  including
arsenic and chromium.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating   and   stabilizing  approximately
20 cubic yards of onsite soil contaminated with
arsenic levels greater than 1,000 mg/kg (referred
to as hot spots), followed  by offsite disposal;
capping  the  remaining   soil  with  arsenic
concentrations  between   10   mg/kg   and
1,000 mg/kg  with  an asphalt/concrete cap;
constructing an enlarged and roofed  drip pad,
which  is consistent with new wood treating
regulations;  allowing  natural  attenuation  to
lower  chromium  levels   in  ground  water;
monitoring  sediment  ground  water,  surface
water, and  air; and  implementing institutional
controls  including  deed  restrictions.    The
estimated present  worth cost for this remedial
action is $322,400, which includes an annual
O&M cost of $6,500 for 30 years.

PERFORMANCE STANDARDS OR GOALS;

Chemical-specific goals for soil  are based on
achieving a  10"5  cancer  risk  level.   The
chemical-specific  goals for ground water  are
based on Federal MCLs including chromium
50 ug/1.  EPA feels that MCLs will be achieved
by natural  attenuation within 3 months after
construction is completed.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to ensure
that  the containment  components  are  not
compromised by future property use.

                                  December 17,1990
 SITE HISTORY/DESCRIPTION:

 The 500-acre  Middletown  Airfield site  is a
 former  military airfield  located between the
 towns of Highspire and Middletown in Dauphin
 County, Pennsylvania. Land in the area is used
 predominantly  for industrial  and  commercial
 purposes.  Several onsite wetlands areas, as well
 as the floodplain of a small stream, have been
 identified onsite. From 1898 to 1917, the site was
 operated by the U.S. Army as a basic training
 camp.  Subsequently, the site was  used  as an
 airfield by the Army/Air Force from 1918 until
 all onsite military operations ceased in 1966. Site
 features include several private manufacturing
 companies,  an  inactive  landfill,  and  the
 Harrisburg International Airport (HIA). The site
 was divided into five distinct study areas where
 soil, sediment, ground water, and surface water
 investigations were conducted. These five study
 areas are: (1) the 30-acre runway area where,
 during the mid-1940s through 1956, wastes from
 base operations were either incinerated or placed
 in a landfill; (2)  the 150-acre industrial area
 where  industrial   operations   such as  paint
 stripping and metal finishing were conducted by
 the Air Force; (3) the 1-acre fire training pit area
 where combustible wastes were burned during
 military training exercises; (4) the 7-acre  north
 base landfill  area where construction debris and
 miscellaneous drums were disposed of from 1950
 to 1956; and  (5) the Meade Heights housing area
 where, prior  to housing construction, wastes may
 have been disposed.  Based on identification of
onsite soil and ground water contamination, the
remedial action for the site was divided into five
operable units (OUs) that were slightly different
from the study areas.  These OUs and their
respective media  of concern  are as  follows:
ground water for the site (OU1); the industrial
area (soil) (OU2); the fire training pit area soil

                                     June 28,1991
SITE HISTORY/DESCRIPTION:

The 83-acre Modern Sanitation Landfill site is an
active landfill in the Townships of Windsor and
Lower Windsor,  York County,  Pennsylvania.
Land  use  in  the   area  is  predominantly
agricultural   and  residential,   with   nearby
woodland areas.   The site includes  an old,
inactive,  unlined 66-acre landfill area, which is
the subject of this ROD, and an adjacent active
17-acre double-lined  landfill area to the north.
Other site features include borrow areas  for
landfill   soil  cover  material;  ground  water
extraction systems to the east, west and south of
the landfill; a  wastewater  treatment  plant; a
landfill   gas-extraction   system;   and  a
low-permeability final cover system. Since the
early 1940's, Modern Trash Removal has used
the site for municipal, and  non-hazardous and
hazardous industrial waste  stream  disposal
activities. Industrial waste disposed of onsite
includes inorganic production residues, pesticide
waste sludge, PCS wastes, and  oil and paint
waste.   In 1977,  a ground water interceptor
trench was constructed to collect leachate from
the west side of the  site.  The collected water
currently is pumped to  the onsite treatment
facility. In 1981, the State detected onsite ground
water contamination  by VOCs on the  western
site border, and in  1983, determined  that the
western interceptor trench should be upgraded
and modified, and that quarterly sampling of
monitoring wells should be implemented  to
detect the leachate seeps and the presence of
leachate  constituents  in ground  water.  As a
result, extraction wells to augment the  western
interceptor trench were  installed.   Leachate
studies   in   1985  also  identified  organic
contamination in the eastern site area; and, as a
result, 13 extraction wells were  installed along
the   eastern   perimeter.     Four   surface
impoundments  were operated onsite  to  treat
ground  water and leachate collected  by the
interceptor and extraction wells.  In 1987, the
surface impoundments were clean closed, and a
replacement treatment facility, which included
metal precipitation, filtration, and air stripping,
was constructed. In addition, as of 1990,64 acres
of the 66-acre unlined landfill had been covered
with a low permeability cap. This ROD provides
a final remedy for the source  of leachate seeps
and ground water constituents.  The primary
contaminants of concern affecting the soil, debris,
and ground water are VOCs including benzene,
PCE,  TCE, toluene, and xylenes; and  metals
including lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
completing the  low  permeability cap and final
cover system over the 66-acre unlined landfill;
expanding the existing ground water extraction
system on both the eastern and western sides of
the site; maintaining the  onsite wastewater
treatment facility that treats extracted ground
water with physical/chemical and  biological
treatment,  followed  by  filtration  and  air
stripping prior  to  discharge  of  the treated
wastewater onsite; managing the landfill gas
collection system; and continuing  ground and
surface water monitoring.  The present worth
cost for this remedial action is $18,078/000, which
includes an annual O&M cost of $1,175,000.

PERFORMANCE STANDARDS OR GOALS:

Ground water clean-up goals are based on State
and   Federal   standards   and   background
contaminant  levels,  whichever  are  lower.
Chemical-specific ground water goals include
benzene 5 ug/1  (MCL), PCE 5  ug/1 (MCL), and
TCE 5 ug/1 (PMCL).

                                   August 12,1991
SITE HISTORY/DESCRIPTION:

The  58-acre NCR, Millsboro site is a former
manufacturing  facility  in  Millsboro,  Sussex
County, Delaware.  Land use in the  area is
mixed  residential, agricultural, and  industrial
with a  small stream, Iron Branch, bordering the
site to  the north and northeast.  From  1965 to
1967,  Dennis   Mitchell   Industries  (DMI)
conducted  manufacturing  operations  onsite.
Reportedly, plating activities and other processes
generated  wastewater and sludge  that were
stored  in an onsite lagoon.  NCR Corporation
purchased the plant in 1967 and manufactured
mechanical cash registers from 1967 to 1975, and
electronic terminal equipment from 1975 to 1980.
NCR's  activities included chromium plating,
enameling,  heat  treating,  and  degreasing
operations using TCE. TCE and oil wastes were
disposed of offsite; and oil, grease, and paint
wastes  were drummed and stored onsite prior to
offsite  disposal.  Waste  sludge associated  with
the chromium  plating  processes was  treated
onsite  and  directed to  onsite  lagoons  for
sedimentation and clarification prior to discharge
to Iron  Branch. NCR also disposed of the waste
sludge  in  a pit along  the eastern  boundary.
From 1981 to 1983 under  State direction, NCR
conducted onsite investigations, which revealed
ground water   contamination  by  VOCs  and
chromium above levels of concern.  In 1981,
NCR   excavated  and  disposed  of  offsite
approximately 315 cubic yards of lagoon sludge
and other  wastes during RCRA closure of the
facility. In 1988, NCR installed a ground water
recovery  well   and air  stripper  to  prevent
continuing migration of a TCE ground water
plume.  This ROD addresses a final remedy for
ground water  contamination.   The  primary
contaminants of concern affecting the ground
water  are  VOCs,  mainly  TCE; and  metals
including chromium.
SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
pumping and treatment of contaminated ground
water using  air stripping, followed by  carbon
adsorption, and  coagulation  and filtration, if
necessary, to remove chromium; controlling air
emissions  from  the ground  water treatment
system,  if necessary; discharging  the  treated
water onsite to surface  water and/or through
ground water infiltration galleries; conducting a
well survey to identify all wells located within a
one-mile radius of the site; conducting sediment,
ground water, and surface water monitoring;
and   implementing   institutional  controls
including  ground  water   use   and   deed
restrictions.  The estimated present worth cost
for this remedial action is $4,749,000, which
includes an annual O&M cost of $859,000.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water clean-up goals
are based  on  SDWA  MCLs  and non-zero
MCLGs, and include TCE  5  ug/1  (MCL) and
chromium  100  ug/1   (MCL).     Discharge
limitations are SDWA   MCLs  and non-zero
MCLGs; SDWA Underground Injection Control
limits; CWA-NPDES;  CWA-AWQC; and State
requirements.

INSTITUTIONAL CONTROLS:

Deed and ground water use restrictions  will be
implemented to prevent  land and ground water
use.

                        OLD CITY OF YORK LANDFILL, PA
                                  September 30,1991
 SITE HISTORY/DESCRIPTION:

 The 178-acre Old City of York Landfill site is a
 municipal   waste   landfill   in   Springfield
 Township, York County, Pennsylvania. Land in
 the   surrounding   area   is   predominantly
 agricultural and wooded. The site is bounded to
 the southeast and the northwest by tributaries to
 Codorus Creek, and these tributaries are partially
 fed by seeps discharging from the valley  and
 hillsides near the landfill. Ten residences located
 within 1/4 mile of the site have or had ground
 water  from  domestic  water  wells  as  their
 drinking water supply.  From 1961 until its
 closure in 1975, the City used 56 acres of the site
 as a  landfill for municipal wastes;  however,
 some industrial waste was  also disposed of at
 the site.   In 1978,  the  property  was sold to
 private owners. After local residents expressed
 concern over water quality,  the State conducted
 a residential well sampling  program from 1981
 to 1985. VOCs were identified in six residential
 wells;  as  a  result,  public  water main  was
 installed at the  site.  In 1982, the State notified
 the City and site owners that operation of and
 existing conditions  at  the landfill  were in
 violation of the Clean Streams Act and directed
 the city to conduct a site assessment to evaluate
 clean-up measures.  During 1987 and  1989, the
 City, under a State order,  installed a ground
 water recovery and treatment system connected
 to an air stripping  tower,  which has not yet
started operation.  Eight onsite collection vaults
containing  a  total  of  1,120 cubic  feet of
orange-tinted sediment and water are located on
the site.  These vaults are part of an old leachate
collection system that is no longer functioning.
In 1991, the owner placed a deed restriction on
the entire site to prevent ground water and
 surface water  usage,  additional  agricultural
 usage, subdivision  of  the  property, and  soil
 disturbance. This ROD addresses the long-term
 threats to  soil, ground water, and surface water
 produced  by the landfill and  vault sediment.
 The primary contaminants of concern affecting
 the soil and ground water are  VOCs including
 benzene, PCE, and TCE.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 restoring and revegetating the soil cover in the
 northeastern portion of the  site;  disposing of
 vault sediment offsite;  installing a diversion
 swale along South  Road; installing a ground
 water  recovery/treatment  system  using  the
 existing air stripper, or adding  additional ones,
 as  needed,  with  onsite  discharge  to surface
 water; installing a landfill gas venting system
 with monitoring probes; maintaining perimeter
 fencing at the leachate  collection values; and
 monitoring ground  water, surface water, and
 sediment.  The estimated present worth cost for
 this remedial action is $8,291,080, which includes
 an annual  O&M cost of $259,080 for 30 years.

 PERFORMANCE  STANDARDS OR GOALS:

 Remediation of ground water will continue until
 contaminant levels  meet the  lower  of site
 background levels, which are methods detection
 limits; and Federal and State standards including
 SDWA MCLs, proposed MCLs, and risk-based
 levels.

                                     June 28,1991
 SITE HISTORY/DESCRIPTION:

 The 37-acre Publicker/Cuyahoga Wrecking Plant
 site is a former liquor  and industrial alcohol
 distillery in Philadelphia, Philadelphia County,
 Pennsylvania. Surrounding land use is primarily
 industrial, with 400,000  people living within a
 1-mile radius of the site.  From 1912 until 1986
 when  the  plant  closed,  alcohol   distilling
 operations  were conducted onsite.  From the
 1970's to 1980's,  the site  was also used as a
 petroleum and chemical storage facility,  which
 utilized 440 large above-ground tanks, stored
 chemicals, chemical laboratories, reaction vessels,
 production  buildings,  warehouses,   a  power
 plant,   and  several   hundred  miles   of
 above-ground process lines, many of which were
 wrapped with asbestos insulation.  In 1987, a
 CC>2 utilization area was destroyed in an  onsite
 fire, which  was  accompanied  by numerous
 explosions.   Subsequent onsite inspections by
 EPA and the State identified leaking tanks, pits,
 and process lines  containing  fuel  oil, and
 shock-sensitive explosive materials, and  7,000
 gallons of reactive and flammable materials in
 fermentation tanks and grain dryers.  In 1987,
 EPA stabilized the site by bulking flammable
 and explosive  materials  onsite for  future
 disposal, disposing of highly reactive laboratory
 wastes and cylinders offsite, crushing  3,100
 empty drums,  wrapping  overhead   asbestos-
 covered process lines with  plastic, and bagging
 and storing  loose  asbestos  materials onsite.  A
 1989 ROD addressed operable unit 1 (OU1) and
 Provided for offsite treatment and disposal of
 hazardous   waste  streams  and   chemicals
 recovered   from  within  the process  lines,
 demolition of the above-ground process  lines,
 and packaging and onsite storage of asbestos
 arťd other  insulation  materials.   This  ROD
addresses a portion  of  OU2, specifically  the
 bulked asbestos stored onsite, any remaining
asbestos material attached to overhead exterior
P'pelines, and a pile of asbestos debris near a
loading pier. A subsequent ROD will address
onsite soil and ground water contamination. The
primary  contaminant  of concern  present  as
debris is asbestos, an inorganic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
removing approximately 150 cubic yards  of
asbestos  from overhead extraction pipes and
placing this material in plastic bags; staging this
material, along  with 6 cubic yards of asbestos
from near a loading pier and 1,100 cubic yards of
bagged  asbestos from previous  removal and
remedial actions; and  disposing of the staged
asbestos offsite.  The estimated  present worth
cost for this remedial action is $293,420. There
are no O&M costs associated with this remedial
action.

PERFORMANCE STANDARDS OR GOALS:

All bulked and remaining loose asbestos material
will be removed from the site. No specific clean-
up standard for asbestos  was provided.

                                     June 28,1991
 SITE HISTORY/DESCRIPTION:

 The 26-acre Resin Disposal site is an inactive
 industrial landfill and former coal strip mining
 area in Jefferson Borough, Allegheny County,
 Pennsylvania.  The site is bordered to the north
 and west by residential areas,  and to the east
 and south by undeveloped land.   The  site
 overlies a bedrock aquifer, and is also in contact
 with the Pittsburgh Coal Formation, a source of
 non-potable ground water.  Prior  to 1950, coal
 strip mining operations were conducted on and
 near the site. From 1950 to 1964, 85,000 tons of
 process  wastes  consisting of  petroleum and
 coal-derived chemicals mixed  with clay were
 disposed of in a previously mined onsite area,
 and earthen dikes were used to  contain these
 wastes.   Between 1980  and  1984, private
 investigations identified that contaminants from
 the landfill had migrated to the Pittsburgh Coal
 Formation, and  the soil and perched ground
 water downslope. Subsequently, the site owners
 installed a leachate collection  system and an
 oil/water separator. EPA investigations in 1988
 further characterized contaminated media and
 analyzed potential contaminant  pathways. This
 ROD  addresses   source control,  as well  as
 preventing migration of contaminated ground
 water in the Pittsburgh Coal  Formation.   A
 subsequent ROD will address any remediation of
 ground water that may be necessary.   The
 primary contaminants of concern  affecting soil,
 debris, and ground water are VOCs including
benzene,  toluene, and xylenes;  and  other
 organics including napthalene,   PAHs,  and
 phenols.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
capping the landfill with a multi-layer cap, and
upgrading the landfill dike; relocating a sanitary
sewer located along the northeast border of the
landfill to allow future access without disturbing
the landfill cap; installing  a  new oil/water
separator for leachate treatment, with discharge
of aqueous phases  to a POTW,  and possible
offsite reclamation  of NAPLs  for use as an
energy source; installing a skimmer well system
to remove NAPLs from ground water for use as
an energy source; monitoring ground water and
surface  water; and  implementing institutional
controls including deed restrictions,  and site
access  restrictions  such  as fencing.    The
estirrj-Jted  present worth cost for  this remedial
action is $4,348,000, which includes an annual
O&M cost of $132,000 for 30 years.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The  7.3-acre Saunders Supply site is an active
lumber   yard  facility  in  the  Village   of
Chuckaruck, a rural area of the City of Suffolk,
Virginia. Land use in the area is predominantly
mixed residential  and commercial.  The site is
composed of  the Saunders Supply  Company
property and  a portion of the adjacent Kelly
property.    Commercial  establishments  and
residences are to the east of the facility, and a
wooded area is to the west. From 1964 to 1991,
the Saunders Supply Company used  the site to
chemically treat wood before distribution. Prior
to 1984,  treated  wood was placed on pallets
located directly on the ground near  the wood
treating process area.  Subsequently,  from 1984
to 1991 when the site ceased operations, treated
wood was  air-dried on a concrete  drip pad.
These improper treatment and disposal processes
have contaminated  onsite  soil, sediment, and
ground water.  Principal site features include the
treatment facilities,  a  former conical bum pit
area, a former earthen separation pond, and a
wastewater  pond  west of  the site.   Some
drainage from the site discharges  to storm
sewers adjacent to the site boundary.  After the
State investigated the site, Saunders Supply was
required to install monitoring wells, excavate the
contaminated soil around  the conical burn pit
area, and install a recovery well. Treated water
from the recovery  well was recycled  as  the
process  water for the chemical treatment  of
lumber.     EPA  conducted  additional
investigations  that  revealed the presence  of
pentachlorophenol (PCP), arsenic, and chromium
in the ground water.  This ROD addresses all
media impacted by site contamination as a final
remedy.  The primary contaminants of concern
affecting soil, sediment,  debris, ground water,
and surface water are organics including dioxins
and  PCP; and metals including arsenic  and
chromium.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
draining  the wastewater from  the wastewater
pond, followed by onsite or offsite treatment and
discharge;   excavating,   treating   using
dechlorination, and offsite disposal of 700 tons of
sediment from the  wastewater  pond and  the
former earthen separation  pond; excavating,
treating onsite using low-temperature thermal
desorption (LTTD), and offsite disposal of 24,300
tons of soil and sediment from the storm sewer
exceeding 1.46 mg/kg PCP; regenerating spent
carbon from the LTTD treatment process offsite;
treating ground water  during  the dewatering
process prior to excavating the soil; discharging
the treated water onsite or offsite based upon
remedial  design studies;  testing the concrete
pads for RCRA characteristic hazardous wastes;
scarification of the top  1  inch  of the concrete
pads and treating the removed  material  using
solidification   if  determined  to  be   RCRA
characteristic  waste, with subsequent  offsite
disposal  along with  the remainder  of  the
concrete   pads;  removing  and   plugging
preexisting wells; cleaning and sliplining  the
storm  sewer;  monitoring ground water; and
implementing  institutional controls  including
deed and ground water use restrictions.  The
estimated present worth cost for this remedial
action is  $20,485,000, which includes  an annual
O&M cost of $15,000.

PERFORMANCE STANDARDS OR GOALS:

The chemical-specific soil clean-up level is PCP
1.46 mg/kg.   If ground  water is discharged
onsite, treated effluent must meet State permit
limits;  or if discharged  offsite,  treated effluent
must meet levels set by  the receiving  facility.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 2-acre Sealand Limited site, a former coal tar
treatment and recycling facility, is located in Mt
Pleasant, New Castle County, Delaware.  Land
use  in  the  area  is  primarily industrial and
commercial.  Current site features  include a
concrete   slab,  a   one-story  building,  an
abandoned  rail  spur,  a gravel road,  and
miscellaneous debris. Ground water underlying
the site is used as a source of drinking water.
From 1971 until 1976, Adams Laboratory used
the site for animal fat rendering activities.  The
property was  subsequently  sold  to Conrail,
which  cleaned up the property to meet State
standards in 1979.  From 1982 to 1983, Conrail
leased  the  property to  Sealand.   Sealand
allegedly conducted treatment processing, and
recycling of coal  to tar and off-specification
creosote wastes onsite until abandoning the site
in 1983. A1983 State investigation discovered 21
steel tanks or hoppers; a 10,000-gallon wooden
storage  tank and 300 55-gallon sleel drums,
which  were leaking liquids  onsite;  a boiler
house;  and various  mixing  chambers  and
pressure   vessels   on  the  abandoned   site.
Additional  studies  by  EPA and  the  State
identified orgardcs including PAHs, creosols, and
solvents in the onsite soil, drums, and tanks.
Subsequently in  1983,   EPA  conducted  an
emergency  removal  action  at  the  site  and
removed offsite 240,000 gallons of organic wastes
from within the wooden and steel tanks, and 320
drums. Additionally, EPA disposed of 122 cubic
yards of solid waste, including 30 cubic yards of
wooden tank debris and approximately 50 to 92
cubic yards of sludge and contaminated material
offsite.   The owner  voluntarily removed 239
drums of off-specification product.  In addition,
the storage tanks were cleaned and moved, and
the tank and drum storage area was capped with
clay. This ROD addresses onsite soil as the first
and final operable unit (OU1). All hazardous
materials contained in abandoned  onsite  tanks
and drums were disposed of offsite during the
EPA removal action, and any remaining soil
contaminants pose low risks for humans at the
site.  Based on this rationale, there  are no
primary contaminants of concern affecting this
site.

                                     June 28,1991
SITE HISTORY/DESCRIPTION;

The 22-acre Strasburg Landfill site is an inactive
landfill located within a 220-acre tract of land in
Newlin and West Bradford Townships, Chester
County, Pennsylvania. The site is characterized
by hills draining toward Brandywine Creek and
its  floodplain, which forms  the southern and
western site boundaries.  The nearest wetland is
the  Briar  Run  watershed  located  600 feet
east/southeast of the site. The 201 single-family
residences that  surround the site use ground
water as a source of drinking water.  Before
landfilling operations began in 1973, the site was
used as  farmland.   From  1978 to 1983,  the
landfill  accepted  industrial  and heavy  metal
wastes and sludge.  State investigations in 1979
determined that landfill operations had resulted
in excessive siltation of Briar Run.  In 1980, the
State permanently prohibited the landfill from
receiving industrial waste.  In 1983, the owners
were cited for violations, which they failed to
correct, and the State ordered the landfill closed.
Closure involved constructing a PVC cover and
soil and vegetation  layer.  Subsequent studies
detected VOCs in both onsite monitoring wells
and offsite residential wells.  The State  initiated
an interim action to  control the leachate, which
included collection  and  offsite  treatment  of
leachate at a nearby municipal sewage plant and
installing diversions to  halt  leachate flow.   A
1989 ROD addressed contaminated residential
wells and exposure pathways, and provided an
interim remedy to limit site access.  The purpose
of  this  ROD is  to limit  direct  contact and
exposure to  contaminants  using  site access
restrictions, and to reduce further degradation of
the  landfill cover.  Remediation of the landfill
will be addressed in a future ROD.  The primary
contaminants of concern affecting soil and debris
are  VOCs including benzene, PCE, TCE, and
toluene;   and  metals  including arsenic  and
chromium.
SELECTED REMEDIAL ACTION:

The selected interim remedial action for this site
includes  implementing site access  restrictions
including fencing  that will encompass the
immediate  landfill  area,  access  roads, the
sediment pond, air  stripping building, and
monitoring wells; and maintaining the fence and
the existing cap.  The  estimated  total present
worth cost for this remedial action  is  $823,020,
which includes an annual O&M cost of $55,405.

                                 September 27,1991
 SITE HISTORY/DESCRIPTION;

 The 17,000-acre USA Aberdeen - Edgewood site
 is a military ordnance installation in Edgewood,
 Maryland.  The 4.5-acre Old O-Field site, which
 is the focus of this ROD, is a fenced hazardous
 waste and ordnance disposal area located within
 the lower half of the Gunpowder Neck in the
 Edgewood  area  of  the  Aberdeen  Proving
 Ground.    Land  use in the area consists of
 military  testing  ranges,  with a  mixture  of
 industrial, military, and civilian residential areas.
 The site  overlies two aquifers that drain into
 Watson Creek and the Gunpowder River, which
 border  the  site.     From   1941  to  1952,
 chemical-warfare  agents  including  mustard,
 lewisite, adamsite, white phosphorus, munitions,
 contaminated  equipment,  and miscellaneous
 hazardous waste were disposed of in 35 onsite
 unlined pits and trenches. Studies have shown
 that  chemicals  buried  within the  pits have
 impacted ground water and also interconnecting
 surface water in Watson Creek.  From 1949 to
 the mid-1970's, several  decontamination and
 clean-up operations were conducted as a result
 of munitions explosions, which spread mustard
 into the surrounding soil, air, Watson Creek, and
 Gunpowder River. These operations included
 the   application   of  1,000   barrels   of
 decontaminating  agent  non-corrosive (DANC)
 containing chlorinated hydrocarbons; soaking the
 field with several hundred gallons of fuel oil and
 setting the field ablaze; dispersing lime into the
 surrounding trees to further reduce the amount
 of mustard present; and using supertropical
bleach, lime, and sodium hydroxide to destroy
chemical  agents.   Evidence shows that these
decontamination efforts  have  contaminated  the
ground water  with chlorinated hydrocarbons.
Subsequent  remediation activities were limited to
removing and securing ordnance items on the
surface.  The site has been divided into three
operable units (OUs) for remediation. This ROD
provides an interim remedy  for contaminated
ground water and its effect on surface water, as
OU1.  Future RODs will address contaminated
onsite  soil and surface water.   The  primary
contaminants of concern affecting the ground
water are VOCs including benzene, PCE, TCE,
and toluene; and metals including arsenic.

SELECTED REMEDIAL ACTION:

The selected  remedial action for this interim
remedy  includes  installing  a downgradient
extraction well  network; pumping and onsite
treatment of contaminated ground water using
chemical   precipitation,   followed   by
ultraviolet-oxidation;  monitoring  the treated
effluent, then discharging the effluent onsite to
the Gunpowder River; and disposing of  the
contaminated chemical precipitation filter cake
sludge generated during the treatment process
offsite. The estimated present worth cost for this
remedial action is $9,120,000, which includes an
estimated annual O&M cost of $466,650 for 30
years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water clean-up goals
are based on CWA  Ambient  Water Quality
Criteria, and SDWA MCLs and proposed MCLs,
and include benzene 5 ug/1 (MCL), PCE 5 ug/1
(MCL),  TCE 5  ug/1 (MCL),  toluene 40 ug/1
(PMCLs), and arsenic 50 ug/1 (MCL).

                                September 27,1991
SITE HISTORY/DESCRIPTION:

The 79,000-acre USA Aberdeen site, also known
as the U.S. Army Aberdeen  Proving Ground
(APG), is an  active military  installation used
since  1917 for planning and  testing weapons,
munitions, vehicles, and equipment in Harford
County, Maryland,  near  the  head  of the
Chesapeake Bay.   APG  is divided into two
functional areas: the 13,000-acre Edgewood Area
and  the  17,000-acre  Aberdeen  Area,  which
includes two  landfills.  These  two areas are
divided and drained by Bush River, as well as
by numerous  creeks.   From  1922 to  1925, an
unknown  amount  of World  War  I   white
phosphorus  munitions   (ordnance)  was
supposedly buried  offshore of  the Aberdeen
Area  on  the  western  side of  the  upper
Chesapeake Bay. This  15-acre area, termed the
White Phosphorus Underwater Munitions Burial
Area (WPUMBA), is the focus  of  this ROD. The
ordnance reportedly buried  at  the WPUMBA
consisted of land mines, grenades, and artillery
shells; in addition, bulk phosphorus may have
been  buried.    In  1933,  the WPUMBA  was
reportedly uncovered by a hurricane, resulting in
a large waterfowl kill. However, no evidence of
a disposal site  at the WPUMBA was observed in
historical or aerial photographs, and only one
reference to the disposal area has been found. In
addition to background searches, EPA conducted
extensive electromagnetic  and  core sampling
studies of the WPUMBA  from  1988 to  1989.
Sample results revealed only  trace amounts of
white phosphorus and  only sporadic magnetic
objects in  sediment,  and no phosphorus in
surface water.  Hence, no effective remedial
action is possible at the site. Future RODs may
be  warranted  if  contamination  is  found.
Therefore, there are no primary contaminants of
concern affecting the site.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site is no
action with surface water monitoring after severe
storms with hurricane strength winds or any
other act which may disturb sediment.  Water
samples will be analyzed for phosphorus, using
a detection limit of 0.01 ug/I, which is 10 percent
of  the established  toxicity   concentrations
approved by EPA, and  for metals using EPA
detection limits. There are no present worth or
O&M   costs associated  with  this  no  action
remedy.

                                   August 2,1991
SITE HISTORY/DESCRIPTION:

The  250-acre USA  Letterkenny-PDO site  is
within the 19,500-acre active U.S. Army facility
in   Chambersburg,  Franklin  County,
Pennsylvania. Land use in the area is primarily
agricultural,  with  scattered residences  and
military facilities. Shallow ground water at the
head of the site flows toward and into Rocky
Spring and Rocky Spring Lake. Since  1942, the
U.S. Army has used the PDO Area to overhaul,
rebuild, and test wheeled and tracked vehicles;
distribute class III chemicals and petroleum; and
store,  maintain, demilitarize,  modify,  and
demolish ammunition.  These past industrial
activities involved the onsite use of solvents, oils,
hydrocarbons, and metals, which were disposed
of in an oil burning pit and several drum storage
revetments. From 1987 until 1989, a number of
EPA   investigations  documented   soil
contamination near the drum storage  area and
the oil burning pit; and these areas are thought
to  be   the  primary  sources   of  onsite
contamination. This ROD addresses remediation
of onsite soil as the first operable unit (OU1). A
subsequent ROD will address  ground water
contamination as OU2. Because a majority of the
soil contaminants have already moved down into
the clays and silts of the underlying bedrock and
ground water, soil contaminants now pose low
risks for humans at the site, and no remediation
of the soil is necessary. Based on this rationale,
there are no  primary  contaminants of concern
affecting this site.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site is no
action. There are no costs associated with this
no action remedy.

SITE HISTORY/DESCRIPTION:

The USA Letterkenny Southeast Area site is on
a  19,500-acre  active  U.S.  Army  facility  in
Chambersburg, Franklin County, Pennsylvania.
Land use in the area  is  primarily agricultural
with scattered residences and military facilities.
Ground water flowing beneath the Southeast site
discharges into two nearby streams.  Drinking
water in the 33 residences  located within a
3-square-mile radius  of  the  facility  has been
affected by ground water contamination from the
site.  Since 1942, the U.S. Army has used the
Southeast Area  to overhaul,  rebuild, and  test
wheeled and tracked vehicles; distribute Class III
chemicals and petroleum; and store, maintain,
demilitarize, modify, and demolish ammunition.
These activities past industrial have involved the
use and disposal of TCE, solvents, hydrocarbons,
and metals. As a result of a Federal Interagency
Agreement,   EPA  conducted  several
investigations that identified VOC-contamination
of onsite soil in  the K Area associated with the
various burial trenches, pits, and landfills used
for hazardous  waste disposal.   This ROD
addresses contaminated  soil  in  the Southeast
Area, and is the  first operable unit for that area.
Future  RODs will address other contaminant
source  areas and ground water.  The primary
contaminants of concern affecting the soil are
VOCs including TCE and xylenes.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and treating onsite 8,000 cubic yards
of VOC-contaminated soil using low temperature
thermal  treatment;   controlling  vaporized
contaminants   using  a  secondary   high-
temperature combustor, or collecting these
vapors by adsorption onto activated carbon;
backfilling the residual ash onsite; disposing of
the residual carbon offsite; artd conducting soil
monitoring.  The estimated present worth cost
for this remedial action is $1,539,191. There are
no  O&M costs associated with  this remedial
action.

PERFORMANCE STANDARDS  OR GOALS:

Soil excavation levels will be set at 225 ug/kg for
all contaminants  to ensure that  the  levels  of
indicator chemicals in ground water will meet
the State ground water requirements.

                                  December 17,1990
 SITE HISTORY/DESCRIPTION:

 The 22-acre Whitmoyer Laboratories site is an
 abandoned   animal   pharmaceutical
 manufacturing  facility in Jackson Township,
 Lebanon County, Pennsylvania. Land use in the
 area is predominantly agricultural, and there are
 wetlands areas adjacent to the site.  Part of the
 site lies within the 100-year floodplain of the
 Tulpehocken  Creek-Union  Canal,   and  an
 estimated 40 residences in the vicinity of the site
 use the underlying aquifer  as  their  drinking
 water supply.  From 1957 to 1964, Whitmoyer
 Laboratories, Inc., produced  organic arsenicals
 onsite.  In 1964, the  new site owners, began
 storing concentrated wastes in an onsite concrete
 vault and, until 1971, conducted onsite pumping
 and treatment  of  ground water and ocean
 dumping of wastes.   In 1977, sludge  from
 ground  water  treatment was placed in onsite
 lagoons in the eastern area of the site.  Between
 1978 and 1982, the site changed ownership twice,
 and then in 1985, a RCRA site closure plan was
 filed. In 1986, EPA provided bottled water to
 residences  with  contaminated  ground  water.
 Onsite contamination of soil and ground water
 has  resulted from a combination  of  poor
 housekeeping,  poor disposal  practices,  and
 improper storage of hazardous  materials.  In
 1986, arsenic contamination was  detected in
 nearby residential wells by EPA.  When the site
 was abandoned in 1987, very little of the RCRA
 closure plan had been implemented. From  1988
 to 1990, EPA removed the abandoned drums and
 laboratory wastes from the site.  A 1989 ROD
 provided for offsite removal of concentrated
 liquids in abandoned tanks and process vessels
 as the first  operable unit (OU1).   This ROD
addresses OU2, which includes remediation of
chemical vault and lagoon wastes, out-dated
products,    miscellaneous  chemicals   and
 feedstocks, and contaminated site structures. A
 ROD for OU3 will addresses remediation of
contaminated onsite soil and ground water.  The
primary contaminants of concern affecting the
debris and sludge are VOCs including benzene,
PCE, toluene,  and  xylenes;  other  organics
including phenols; and metals including arsenic
and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and incinerating onsite approximately
3000 cubic yards of high organic content vault
wastes, and  approximately 101 cubic yards of
miscellaneous products and feedstocks, followed
by   cement/pozzolan-based   fixation,   and
disposing  of  the  residual ash  offsite;  treating
approximately 1,500 cubic yards of low organic
content vault wastes using fixation or a similar
fixation  process, followed by offsite  disposal;
excavating and incinerating onsite approximately
20 buried drums and 50 cubic yards of tank and
process vessel residuals, followed by treating any
residual ash using fixation, and offsite disposal
of residuals;  excavating approximately 24,000
cubic yards  of arsenic-contaminated lagoon
wastes with levels above 10,000 mg/kg, followed
by fixation of the hazardous lagoons wastes; and
disposing of residuals along with nonhazardous
wastes and other products and feedstocks offsite;
demolishing buildings, associated tanks, vessels,
processing equipment, and debris; incinerating
onsite any combustible debris exhibiting  the
RCRA arsenic toxicity characteristic, followed by
offsite  disposal;   coating  and    sealing
noncombustible  permeable  demolition  debris
prior to offsite disposal; surface cleaning of
noncombustible  impermeable demolition debris,
which  exhibit  the  RCRA  arsenic   toxicity
characteristic and contaminated onsite structures
before offsite disposal; and  offsite  disposal or
recycling of  untreated unsalvaged demolition
debris. The estimated present worth cost for this
remedial action  is $45,800,000.   There are no
O&M costs associated with this remedial action
due to selection  of offsite disposal for residuals.

SITE HISTORY/DESCRIPTION:

The  22-acre Whitmoyer Laboratories site is an
inactive laboratory facility in Jackson Township,
Lebanon County, Pennsylvania. Land use in the
area is predominantly agricultural with adjacent
wetlands areas. In addition, part of the site lies
within   the   100-year   floodplain   of  the

20 residences in the vicinity of the site use the
underlying aquifer  as their  drinking water

Laboratories,  Inc., produced organic  arsenicals
onsite. In 1964, the new owners, Rohm & Haas,
began storing concentrated wastes in a concrete
vault, and until 1971 conducted onsite ground
water  pumping  and  treatment and  ocean
dumping  of  wastes.   In 1977,  sludge from
ground water treatment was placed in lagoons in
the eastern area of the site.  Between 1978 and
1982, the site changed ownership twice, and then
in 1985, a RCRA site closure plan was filed. In
1986, EPA began providing bottled water to
residents with ground water contaminated by
site  activities.  A  public water supply  line
extension is currently being designed and will be
constructed as part of a removal action. When
the site was abandoned in  1987, very little of the
RCRA closure  plan had been  implemented.
From 1988 to 1990, EPA removed approximately
800 abandoned drums and laboratory  wastes
offsite. A1989 ROD provided for remediation of
hazardous  concentrated   liquids,  including
laboratory wastes, abandoned at the  site as
operable unit 1 (OU1). A December 1990 ROD
provided a remedy for vault and lagoon wastes,
miscellaneous products and feedstocks, tanks,
process  vessels, and other onsite structures as
OU2. This ROD addresses contaminated onsite
soil,  sediment, and ground water as OU3.  The
primary contaminants of  concern affecting the
soil,  sediment, debris, and  ground water are
VOCs including benzene, TCE, and PCE; other
organics including PAHs; and metals including
arsenic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and fixation of approximately 61,000
cubic yards of soil/sediment with contaminant
concentrations above the "principal threat" action
levels using  an  iron-based or  other fixation
process, followed  by offsite  disposal;  using
biological  treatment  for approximately 5,600
cubic yards  of  soil/sediment  with organic
concentrations above  the  "principal  threat"
organic chemical action  levels for the heavily
contaminated soil either prior to or following
fixation, followed by offsite disposal; excavating
and  consolidating  onsite in the vadose zone
approximately   39,000   cubic   yards   of
soil/sediment having contaminant concentrations
below the "principal threat" action levels but
above  ground  water-based  unsaturated  soil
clean-up  targets,  followed  by  capping with
low-permeability materials; placing onsite in the
vadose zone approximately 16,000 cubic yards of
soil/sediment with concentrations  below the
ground  water-based unsaturated  soil  action
levels; soil capping any remaining contaminated
surface soil that contains arsenic  concentrations
greater than  21  mg/kg and  other disturbed
areas,  as  needed;  backfilling,  grading,  and
revegetating  the  excavated areas; demolishing
onsite  structures,  followed   by   salvaging
non-hazardous debris  and  offsite  disposal of
unsalvaged   debris;   onsite  pumping   and
treatment of contaminated ground water using
physical,  chemical, and possibly  biological
treatment, followed by either onsite discharge to
surface water, reinjection into the  aquifer, or
both methods;  disposing  of any  treatment
residuals  offsite;  conducting long-term ground
water   monitoring;    and  implementing
institutional controls including deed restrictions

 Additionally, this ROD provides a contingency
 for  ground water if it  becomes technically
 impracticable to achieve clean-up goals.  The
 contingent remedy includes pumping from the
 perimeter area only to prevent migration of the
 contaminant  plume.   The estimated present
 worth cost for this remedial action is $77,300,000,
 which includes annual O&M costs of $2,397,600
 or $2,477,600 (depending on the ground water
 discharge option chosen).

 PERFORMANCE STANDARDS OR GOALS:

 Soil action levels for saturated and unsaturated
 soil  and "principal threat" action levels were
 developed based on the threat due to inhalation/
 ingestion and  to ground  water using MCLs,
 RCRA toxicity characteristic levels (TCLP), and
 health-based criteria.  The target clean-up goal
 for surface soil is arsenic 21 mg/kg. The action
 levels for unsaturated soil include  benzene
 0.009 mg/kg/   PCE   0.051   mg/kg,  TCE
 0.017 mg/kg, and arsenic 450 mg/kg.  This will
 reduce the  excess cancer  risk  level associated
 with inhalation/ingestion exposure to 10"6. The
 action levels for saturated  soil include  benzene
 0.002  mg/kg,  PCE  0.012   mg/kg,   TCE
 0.004 mg/kg, and arsenic  210 ug/kg based on
 protection of ground water.   Principal threat
 action levels include  benzene 10 mg/kg, PCE
 14 mg/kg,   TCE   10  mg/kg,  and  arsenic
 1,000 mg/kg. Ground water clean-up goals are
 based on Federal MCLs, proposed MCLs, and a
 10"6 excess cancer risk level and reference dose
 equal to 1 for noncarcinogens. Chemical-specific
 ground  water  clean-up goals include benzene
 0.005 mg/1 (MCL), PCE 0.005 mg/1 (pMCL), TCE
 0.005 mg/1  (MCL),  and arsenic 0.05  mg/1. A
State  ARAR  to  remediate ground  water to
background  levels will be waived because of
 technical impracticability.   If  the  contingent
remedy is employed, an ARAR to comply with
SDWA MCLs will also be waived because of
technical impracticability.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prevent

                          WILLIAM DICK LAGOONS, PA
                                     June 28,1991
SITE HISTORY/DESCRIPTION:

The 4.4-acre  William Dick Lagoons site is a
chemical wastewater disposal site in West Cain
Township, Chester County, Pennsylvania. Land
use in the area is predominantly residential and
agricultural,  with adjacent  woodlands.   An
estimated 30 residences located within 1,000 feet
of the site use private wells for their drinking
water supply. Two other Superfund sites are
near the site:  the Blosenski Landfill located 1.7
miles southeast; and the Welsh Landfill, 5 miles
to the northwest. Originally, the site consisted of
three unlined  earthern  lagoons   or  ponds
covering 2.2 acres and an associated borrow area.
From the WSffs to 1970, Mr. William Dick used
the lagoons to dispose of wastewater left  from
cleaning the interiors of chemical and petroleum
tank trailers  owned  primarily  by Chemical
Leaman  Tank  Lines (CLTL),  and  residual
chemical products. In 1970, the State ordered the
lagoons closed after 37  wild geese  descended
into the lagoons,  and were coated with waste.
Later in 1970, vandalism caused the release of an
estimated 300,000 gallons of wastewater into
Birch Run, a tributary of the West  Branch of
Brandywine Creek. As a result of this discharge,
more than 2,600 fish died, and  water supplies
that used Brandywine Creek as  a water source
were closed.  In 1971, William Dick  and CLTL
began  lagoon  closure  as part  of  a  State
agreement.  Activities during 1971 included the
addition of  alum  to the  wastewater,  spray
irrigation of  the  treated  wastewater into the
woods, and covering and revegetating lagoons
with soil.  During 1985, site studies identified
numerous organic compounds in soil samples,
two spring-fed water supplies, and five wells.  In
1988, EPA required  CLTL to fence around the
site, conduct  yearly monitoring of  residential
wells,  and   install   point-of-entry  treatment
systems for selected  private wells. In 1990 and
1991,  sampling  revealed   TCE   and  other
contaminants in 30  to 40 private wells.  As a
result, CLTL  installed  point-of-entry carbon
filtration units in 12 of the 30 to 40 homes where
contamination in well  water exceeded MCLs.
This ROD provides an interim remedy and
addresses  contaminated residential water  as
operable unit 1 (OU1) and ground water as OU2.
A future ROD will address source control and
will  provide a remedy for the  cleanup  of
contaminated soil. The primary contaminants of
concern affecting the ground water are VOCs
including benzene, PCE, and TCE; other organics
including phenol; and metals,

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
providing  an alternate water  supply to affected
residences by extending the City of Coatesville
Authority's water line; installing a water storage
tank  near the site  to  provide storage  and
pressure feed  for the water line  connections;
monitoring   nearby   springs;   collecting
hydrogeologic data; conducting initial pumping
and onsite treatment of the contaminated ground
water plume using treatment components that
will be selected during interim remedial design,
which   are  expected   to  include  chemical
precipitation and one of more of the following:
granular activated carbon, chemical oxidation,
and  air  stripping,  with possible  emission
controls; discharging the treated  water onsite to
surface water; installing monitoring and recovery
wells to further characterize  the entire plume;
and   implementing  institutional  controls
including  ground water use  restrictions.  The
estimated  present worth cost for this remedial
action  ranges  from  $5,991,000  to $7,028,000,
which includes an annual O&M cost of $305,000
to $330,000 for years  0-5, and $21,000 to 46,000
for years 6-30.

PERFORMANCE STANDARDS OR GOALS:

For OU2, EPA is invoking a waiver for Federal
and  state ground  water clean-up  standards
because  the  remedial  action  is  an interim
measure.   Chemical-specific  ground  water
clean-up goals will be set in the final remedy.

INSTITUTIONAL CONTROLS:

Ground  water  use   restrictions  will   be
implemented  to prevent current  and future
residents from using the contaminated ground
water plume from the aquifer as their drinking
water supply; to encourage the use of the newly
installed waterline;  and to demand periodical
analysis for contaminants of ground water wells
not linked to the extended water line.

            ABERDEEN PESTICIDE DUMPS (AMENDMENT), NC
                                 September 30,1991
SITE HISTORY/DESCRIPTION.

The Aberdeen Pesticide Dumps site consists of a
plant area and four disposal areas in Aberdeen,
Moore County, North Carolina. The five areas
are Farm  Chemicals,. Twin  Sites,  Fairway Six,
Mclver Dump, and Route 211. Surrounding land
use  is primarily residential with some light
industry.  Ground water is the main source of
drinking water for local residents.  From the
1930's  until   1987,   chemical   companies
neighboring the site  blended or formulated
pesticides at the formulation plant located on the
Farm Chemicals area. During operations at the
plant, substantial quantities of pesticide wastes
were disposed of  or  spilled onsite.   After
investigations by EPA's Emergency  Response
Section in 1985 and 1986, several removal actions
were conducted including  removing  surface
contaminants, drums, and soil in several areas.
One  removal action, conducted in 1988, resulted
in the  excavation  of 22,000 cubic  yards of
contaminated  soil,  which  was  subsequently
stockpiled  in  the  Fairway  Six  area.   This
stockpile was  designated as  operable unit  2
(OU2).  A 1989 ROD documented the selected
remedy  for  OU2,  which   included  onsite
incineration of the stockpiled material and onsite
disposal  of  the  residual  ash.    OU2  has
subsequently  been  redesignated  as OU4  and
implementation  of   the   selected  remedy
postponed pending a selected remedy for OU1.
A fourth removal action in 1989 resulted in the
excavation and stockpiling of 3,200 cubic yards
of pesticide-laden soil.  In 1986, pesticides were
detected in drinking water from four municipal
wells and three private wells.   A 1989 EPA
investigation of the remaining areas of the site,
designated as OU1, revealed  a total of 98,733
cubic yards of contaminated  soil, in addition to
that  stockpiled in the Fairway Six and Maclver
Dump Areas, that  require remediation.  This
ROD concurrently addresses surface and
subsurface soil contamination addressed in OU1
and the former OU2, and includes a change of
treatment technology for the former OU2 from
incineration to thermal desorption. The purpose
of this response action is to prevent current or
future exposure to the contaminated soil and to
reduce further contaminant migration into the
ground water.  The  primary contaminants of
concern affecting the soil and debris are organics
including pesticides;  metals including  arsenic,
chromium, and lead; and asbestos, an inorganic.

SELECTED REMEDIAL ACTION:

The  amended remedial  action for  this  site
includes conducting a treatability study using
thermal desorption; excavating  and treating a
total of 123,933 cubic yards of soil from all five
areas including previously excavated  soil from
the Fairway Six and Mclver Dump areas using
an  onsite  thermal desorption process  that
includes an activated carbon adsorption to treat
off-gases, followed by  offsite  incineration of
residual  organics  or  disposal   in   another
appropriate  manner;    disposing   of   the
non-hazardous treated soil onsite in the original
excavated   areas;  onsite   solidification   and
disposal of any residue that remains hazardous
after thermal treatment; removing asbestos and
building demolition at the Farm  Chemicals area;
and  sampling and analyses of  site soil, as
necessary,  to  confirm  clean-up  status.   A
contingent remedy will be implemented if the
results of the treatability study conclude  that
thermal  desorption  is  ineffective   or   cost
prohibitive. The contingent remedy will include
all items detailed  under  the selected remedy
except  that incineration would  be  used as the
treatment   technology   instead  of   thermal
desorption.  The estimated present worth cost for
this  remedial action  is  $29,115,000,  which
includes an annual O&M cost of $115,000.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil excavation levels for each
area are based on a 10~6 risk level and include
arsenic 2,705 ug/kg and chromium 3,909 ug/kg.
The selected remedy will attain Federal and State
ARARs including  RCRA LDR  requirements
through a  treatability variance  for soil and
debris.  An organics  reduction  efficiency  of
90-99.99 percent, as verified using the TCLP, will
be attained. These reductions are not expected
to achieve pesticide levels below background
levels in the area.  The ROD includes alternate
Treatability Variance  Levels, which must be
attained for various structural /functional groups.

                                     June 28,1991
 SITE HISTORY/DESCRIPTION:

 The 2.3-acre Arlington Blending & Packaging site
 is  an  abandoned  pesticide  and  herbicide
 blending and packaging facility in Arlington,
 Shelby County, Tennessee. Land use in the area
 is predominantly residential, agricultural, and
 light   commercial.     Site  operations  have
 contaminated  two  units of  the  underlying
 aquifer, which are not  used as drinking water
 sources.   From  1971  to  1978, the Arlington
 Blending & Packaging Company operated onsite
 to  properly  formulate  and  package various
 pesticide,  herbicide,  and   other  chemical
 formulations. During site operations, spills and
 leaks  of  chemicals occurred  onsite,   which
 resulted  in compounds soaking into soil and
 process building flooring, and migrating  offsite
 via surface run-off.  Process water containing
 hazardous contaminants also was discharged to
 onsite ditches, contaminating adjacent properties
 including a residential area, nearby ditches, and
 other  surface water  bodies.    In  addition,
 numerous barrels and other containers were left
 onsite. Site investigations revealed onsite and
 offsite contamination of soil and ground water.
 In 1983,  EPA initiated  a removal  action, and
 excavated and removed  1,920 cubic yards  of
 contaminated soil with chlordane levels in excess
 of 50 mg/kg and  112 drums containing chemical
 wastes.  In 1990,  as a result of the RI data, EPA
conducted   another  removal   action,   and
excavated and temporarily stored onsite 70 cubic
yards of contaminated  soil from the adjacent
 residential property.  This ROD addresses final
 remediation of primarily pesticide-contaminated
 soil   and  ground   water.     The  primary
contaminants of concern affecting the soil, debris,
and ground water are VOCs including benzene;
other organics including pesticides;  and metals
including arsenic.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating 24,000 cubic yards of contaminated
soil and decontaminating the soil onsite using
ex-situ thermal desorption; backfilling excavated
areas  with treated  soil; dechlorinating  the
resulting  condensed  organic liquid from  the
thermal desorption process, followed by offsite
disposal of the  residual  concentrated organic
liquid; treating and disposal of spent carbon or
sludge  offsite;  temporarily  storing  residuals
onsite,  if needed,  prior   to   treatment  to
treatability levels; and offsite disposal; treating
soil containing levels of arsenic and/or other
trace  metals above  action levels  onsite using
solidification,  followed  by  offsite  disposal;
decontaminating  and   demolishing  onsite
buildings, followed by offsite disposal; pumping
and onsite treatment of contaminated ground
water using activated carbon, followed by onsite
discharge of the treated effluent to surface water
or offsite to a POTW; regenerating spent carbon
granules offsite; monitoring ground water; and
providing  for  a  contingency   remedy  that
involves  treating soil  onsite using  thermal
destruction instead of thermal desorption. The
estimated  present worth cost for this remedial
action  is  $12,170,167, which includes a total
present worth  O&M  cost of $1,605,256 for  30
years.

PERFORMANCE STANDARDS OR GOALS:

Soil clean-up levels are based on protection of
ground water  and reduction of risk through
long-term dermal contact and oral ingestion, and
include arsenic 25,000 ug/kg, which also takes
into   account  background   levels.
Chemical-specific ground  water clean-up goals
are based on SDWA MCLs, and include benzene
5 ug/1.

                                   August  29,1991
SITE HISTORY/DESCRIPTION:

The  4.8-acre  Carolina  Transformer site is a
former electrical  transformer rebuilding  and
repair  facility  in  Fayetteville,  Cumberland
County, North Carolina.  Land use in the area is
predominantly agricultural and residential, with
a wooded/swamp-like area adjacent to the site.
The site may overlie as many as three aquifers,
of which only the shallow confined  aquifer has
been found to be contaminated.  From 1967 to
1982, Carolina Transformer Company rebuilt and
repaired electrical transformers onsite.  During
site operations,  PCB fluids were drained from
transformers  and  improperly  stored  and
managed. From 1978 to 1982, a number of EPA
and   State  investigations   identified  PCB-
contaminated  soil and ground water.  In 1982,
the State determined  that run-off from the site
violated  surface water quality standards  for
PCBs.  In 1984,  EPA began clean-up operations
at the site, and removed and disposed  of 975
tons   of  contaminated  soil  offsite  in  a
RCRA-permitted landfill.  This ROD addresses
final  remediation of contaminated soil, sediment,
debris,  and  ground  water.    The  primary
contaminants  of  concern affecting the  soil,
sediment, debris, and ground water are VOCs
including benzene and toluene; other organics
including dioxin and PCBs; and metals including
arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and treating onsite soil and sediment
contaminated  with PCBs in excess of 1 mg/kg
using a solvent extraction process to separate the
organic contaminants and polynuclear aromatic
compounds from the soil and sediment  and to
lower the solubility and mobility of the inorganic
contaminants; backfilling the excavated area with
treated soil;  solidifying soil and sediment that
does not meet the RCRA Toxicity Characteristic
Rule; demolishing 970 cubic yards of roof and
wall material from three onsite buildings and
transporting the debris  to  an  offsite landfill;
treating  any  remaining  structural  material
contaminated   with   PCBs  in  excess  of
10 ug/100 cm2 using a solvent washing system;
transporting 180 cubic yards of debris and solid
waste to an  offsite landfill  for disposal and/or
treatment; pumping and onsite treatment of
contaminated ground water using precipitation
to  remove   metals   and   activated  carbon
adsorption to remove VOCs, followed by onsite
discharge to  surface water or offsite discharge to
a POTW; dewatering sludge generated from the
ground water precipitation process, followed by
offsite  disposal;  conducting  ground  water
monitoring;  and  establishing  a  contingency
remedy for  ground  water  remediation,  which
includes ground water  engineering  controls,
ARAR waivers, institutional controls, continued
monitoring  of  specified wells, and  periodic
reevaluation of remedial technologies if it is
determined that certain portions of the aquifer
cannot be restored to their beneficial uses.  The
estimated present worth cost for this remedial
action  is $10,474,500,  with an  O&M cost of
$78,100 for years 0-1 and $17,400 for years 2-30.

PERFORMANCE STANDARDS OR  GOALS:

Chemical-specific soil/sediment clean-up goals
are  based  on carcinogenic  risk  and  EPA
guidelines,  and include  dioxin  1.2  x  10"4
(carcinogenic risk) and total PCB 1 mg/kg (EPA
guidelines).   Chemical-specific  ground  water
clean-up goals are based on SDWA MCLGs, EPA
guidance,  and  State  standards, and include
benzene  1  ug/1 (State), chromium  50 ug/1
(MCLG), lead 15 ug/1 (EPA guidance), PCB-1260
0.1 ug/1 (State), and  toluene 1,000 ug/1 (State).

           CHARLES  MACON LAGOON  & DRUM STORAGE,  NC
                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The  17-acre Charles Macon Lagoon  & Drum
Storage site  is  a  former  oil  recycling  and
antifreeze manufacturing facility in Richmond
County, North Carolina. The site is composed of
the 16-acre Charles  Macon Lagoon  & Drum
Storage site and the 1-acre Dockery site, which is
located 2,600 feet north of the Macon site.  Land
use in the area is agricultural, and woodlands
cover over half of the site.  The site overlies an
unconfined   aquifer,   and   surface   run-off
discharges to  Pee Dee River, which runs 1 mile
west of the site. A wetlands area exists between
the site and the river. Four residences are within
100 yards of the site and receive drinking water
from the municipal system.  From 1979 to 1982,
unpermitted waste oil recycling was conducted
at the facility using a large boiler to separate the
waste  oil from  other  wastes.   Site  features
resulting from these  activities include drum
storage  areas, 12  unlined  or partially  lined
oil/water waste  storage  lagoons, buildings,
2 truck tankers, and 14  tanks.  In 1980, State
inspectors observed that several of the lagoons
were overflowing with metal-contaminated oil
and sludge contaminating the ground. They also
discovered  175 deteriorating  55-gallon drums
containing various chemicals including VOCs
and  other organics.   In a  1981 EPA RCRA
compliance  inspection  of   the  Macon   site,
10 violations of RCRA regulations were cited.
Subsequently, a court order required the PRPs to
initiate clean-up  activities at Macon  in  1982,
which  led  to identification of 2,100 drums,
10 tanks, and 11 lagoons of concern.  Private
funds were used  to remove 300 drums and the
contents of one lagoon, as well as to install two
monitoring wells, before being depleted.  EPA
continued site activities  in  1983 by removing
3,123 tons of waste and 137,000 gallons  of oil.  In
1984, EPA conducted similar removal activities at
the Dockery site, and removed 709 tons of waste.
After removal activites for both properties had
been completed  in  1984, all but  one lagoon,
referred to as Lagoon 10, had been excavated
and backfilled. Because of the size of Lagoon 10,
EPA decided to backfill and cap the lagoon
without  excavating  the  contents.    Recent
investigations, however, revealed that site soil
and ground water still pose a threat, particularly
downgradient of source  areas such  as lagoon
areas.    This  ROD  addresses  soil,  vessels
containing  hazardous materials, and  ground
water, which is the principal threat at the site,
and  is  a  final  remedy.     The  primary
contaminants of  concern  affecting the  soil,
sludge,  debris,  and ground  water are VOCs
including PCE, TCE, toluene, and xylenes; other
organics including PAHs; and metals including
arsenic and chromium.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating  VOC-contaminated  soil  around the
Lagoon  7 area using in-situ  vapor extraction,
with a  carbon  adsorption system  to  remove
off-gas  organic  contaminants; excavating and
treating PAH-contaminated soil from Lagoon 10
in an onsite, biological  waste  treatment cell
equipped with a carbon adsorption  system to
control  emissions, followed  by  returning the
treated soil to Lagoon 10 and covering with a
low permeability cap; emptying and dismantling
all  vessels  and  demolishing  buildings  as
necessary, and offsite  disposal or  recycling of
hazardous and non-hazardous wastes; further
sampling of soil, sediment, and  surface water;
pumping and treatment of ground water using
air stripping and coagulation/filtration, followed
by discharging treated water to surface water if
NPDES  standards are  met or to an infiltration
gallery if standards are not met; and monitoring
ground water. The estimated present worth cost
for  this remedial action is  $8,700,000, which
includes an estimated present worth O&M cost
of $5,400,000 for 30 years.

                                  September 30,1991
 SITE HISTORY/DESCRIPTION:

 The  1,500-acre Ciba-Geigy  site is an  active
 chemical manufacturer in an industrial area in
 Mclntosh, Washington County,  Alabama.  A
 wetlands area borders the site property, and part
 of  the site  lies within the floodplain of the
 Tombigbee  River.    From  1952  to  present,
 Ciba-Geigy,   formerly   Geigy   Chemical
 Corporation, has produced  various chemicals
 including DDT, laundry products, herbicides,
 insecticides,  agricultural   chelating   agents,
 sequestering agents, plastic resins and additives,
 antioxidants, and specialty chemicals.  In 1982
 during an investigation of an adjacent chemical
 company, EPA identified onsite contamination in
 a  drinking  water  well on  the  Ciba-Geigy
 property.  In 1985, EPA issued a RCRA permit
 that included a corrective action plan requiring
 Ciba-Geigy to  remove and  treat  ground water
 and surface water  contamination  at  the  site.
 EPA  performed  further   investigations  to
 determine the  extent  of contamination,  and
 revealed  11  areas of waste management  and
 potential contamination.  These areas contain a
 variety   of   waste,  debris,  and  pesticide
 by-products and residues. In 1987, as part of the
 corrective action plan requirements, Ciba-Geigy
 installed  an additional wastewater treatment
 system and ground  water monitoring wells. A
 1989  ROD  provided  for   treatment of  the
 contaminated shallow alluvial aquifer by using
 the  onsite  wastewater  treatment plant  as
 operable  unit  1  (OU1).  This  ROD addresses
 highly contaminated soil and sludge at 10 of the
 11  former waste management areas as OU2.
 Future RODs will address contamination within
 the floodplain including the lower portions of an
onsite drainage ditch and areas in the Tombigbee
River in proximity  of the site (OU3),  and
contamination in the remaining untreated former
 waste management area and the upland portions
of  the  drainage  ditch (OU4).   The  primary
contaminants  of  concern  affecting  the  soil,
sludge, and debris are VOCs including benzene
and toluene; other organics including PCBs and
pesticides (e.g., DDT); and metals including lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for the site includes
excavating  contaminated  soil and sludge from
within the  10 disposal areas until established
clean-up levels are reached  or to a maximum
depth of 20 feet; treating 65,000 cubic  yards of
highly-contaminated soil and sludge onsite using
thermal treatment; evaluating the possibility of
pretreatment   via  solvent   extraction,   low
temperature thermal treatment, or critical fluid
injection and  implementing this  process,  if
advantageous; treating 62,300 cubic  yards of
moderately contaminated soil and sludge using
stabilization/solidification   or  a   proven
innovative  technology; obtaining a treatability
variance to dispose  of the  treated  soil  and
residual ash in an onsite landvault; treating deep
soil areas, where risk-based levels have not been
achieved during excavation to the depth of 20
feet, using  in-situ soil flushing combined with
isolation walls, extraction wells alone, or possibly
extraction wells in combination  with in-situ
vacuum  extraction or in-situ bioremediation,
whichever is found to most effective; backfilling
and revegetating the excavated areas; operating
and maintaining the landvaults for a minimum
of 30  years;   monitoring ground water;  and
implementing   institutional   controls   where
necessary including land and ground water use
restrictions.  The  present worth  costs for  this
remedial action  range  from $94,000,000,  if
solidification of low level contaminated soil is
effective, to $120,250,000, if  incineration of all
contaminated material is required.  O&M costs
were not provided.

 PERFORMANCE STANDARDS OR GOALS:

 Chemical-specific soil clean-up goals are based
 on soil depth.  For soil to a depth of less than 12
 inches, goals are based  on 10"6 risk level for
 carcinogens, and an HI=1 for non-carcinogens.
 Chemical-specific goals for surface soil  include
 DDT17mg/kg.  Subsurface soil clean-up goals
 are based on ground water protection levels, as
 well as a 10~* risk level for carcinogens and an
 HI=1 for non-carcinogens,  and  include DDT
 5,034 to 7,500 mg/kg depending on the area.

 INSTITUTIONAL CONTROLS:
Deed restrictions will be implemented to prevent
ground water usage and to minimize land use
until clean-up levels are achieved.

                        GOLDEN STRIP SEPTIC TANK, SC
                                 September 12,1991
SITE HISTORY/DESCRIPTION:

The 55-acre Golden Strip Septic Tank (GSST) site
is an inactive waste hauling and disposal facility
in  Simpsonville,  Greenville  County, South
Carolina. Land use in the area is predominantly
residential.  The estimated  638 residents  who
reside within a quarter-mile of the site use public
water as their drinking water supply.  From 1960
to  1975, GSST used the  site  to dispose  of
industrial and septic wastes in five  unlined
lagoons. In 1975, GSST applied for an industrial
solid  waste permit to dispose of liquid wastes,
but the State  denied the permit because the
proposed disposal method  was unacceptable.
Subsequently, in 1978, GSST discontinued waste
collection, hauling, and disposal, and filled  in
three  of  the  five  lagoons  by  pushing  in
surrounding berms.  State investigations of the
site began in 1972 and included a site survey  of
lagoons and the  surrounding area.   The State
continued its monitoring after the lagoons were
filled  and graded in 1978 and the results of the
monitoring led to additional investigations by
EPA  in 1984  and  1986  and an RI  and
supplemental RI from 1989 to 1990 and 1990  to
1991,  respectively.    EPA  identified  metal
contamination  in lagoon soil and sludge, and
limited  contamination of ground water.    In
addition, 27 abandoned  drums  that  contained
low levels of contaminants were found  on the
east side of the site. Six of the drums  have been
placed in overpack drums  and stored in an
onsite temporary drum storage area.  This ROD
addresses remediation of contaminated soil,  as
well as sludge and surface  water  from the
lagoons,  as  a  final  remedy.   Ground water
contamination is expected to naturally attenuate
within 2 to  5  years after  source remediation
occurs.  The primary contaminants of concern
affecting the soil,  sludge, and surface water are
VOCs  including benzene, PCE,  toluene, and
xylenes; other organics; and metals including
arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and treating onsite approximately
22,400 cubic yards of soil and 4,200 cubic yards
of sludge using solidification/fixation; backfilling
the treated residuals,  covering the area with
clean soil,  and revegetating the site; discharging
off site 1.9  million gallons of impounded surface
water  from  Lagoons  1 and  4  to a  POTW;
disposing  of drummed liquids, along with other
surface   water;   establishing  Alternate
Concentration Limits (ACLs) for the MCLs that
are periodically exceeded in the ground water to
ensure that  source control measures  have a
positive effect on  ground water; conducting
long-term  ground  water  and  surface  water
monitoring;   investigating  further  the
contamination from the abandoned onsite drums;
and implementing institutional   controls   to
control site development. The estimated present
worth cost for this remedial action is $4,529,000,
which includes an annual O&M cost of $991,500.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil clean-up goals are based
on  health-based  criteria and  include  arsenic
18 mg/kg, cadmium 65 mg/kg, chromium 580
mg/kg, lead 500 mg/kg, PCE 56 mg/kg, toluene
12,000  mg/kg,  and xylenes 120,000   mg/kg.
Ground water ACLs will be established based on
the  arithmetic mean of the first four samples  of
each constituent for that well. For means that do
not  exceed the MCLs, the MCL will  be the
applicable  standard against which ground water
monitoring results will be compared.

                                      June 27,1991
 SITE HISTORY/DESCRIPTION:

 The 16.5-acre Hercules 009 Landfill site is in
 Brunswick, Glynn County, Georgia. Land use in
 the  area  is predominantly  commercial  and
 residential.   Onsite features in  the northern
 7 acres of the site  are a landfill  area with
 6 disposal cells containing approximately 33,000
 cubic yards of 1  percent toxaphene sludge, a
 drainage ditch, and a drainage culvert. Most of
 the estimated 1,400 residents  within 3 miles of
 the site are connected to a public water supply,
 except for 6 homes and a church that use private
 wells as their drinking water supply. From 1948
 to  1980,  Hercules,   Inc.,  manufactured  the
 agricultural pesticide toxaphene. Waste from the
 manufacturing  process  was  accumulated  by
 storing toxaphene-contaminated wastewater in
 the offsite  settling ponds.  In 1975, the State
 permitted the site to accept and dispose of
 pesticide waste including toxaphene, in the 009
 landfill site.  Also disposed of in the landfill area
 were empty toxaphene product drums, process
 sludges, glass, rubble, and trash.  In 1979, a State
 inspection detected elevated levels of toxaphene
 in sediment and surface water in the adjacent
 drainage ditch, and in 1980, the State revoked
 Hercules' operating permit.  In  1983, the State
 required Hercules to install  a  ground  water
 monitoring system to assess site contamination.
 In 1984, because  toxaphene  was found in  a
deep/shallow well cluster in the aquifer beneath
 the site, additional ground  water monitoring
wells were installed.  Hercules closed, covered,
and seeded all landfill cells in accordance with
State solid waste permits. This ROD addresses
operable unit 2 (OU2), the contaminated ground
water, as an interim action.  Future RODs will
fully address the principal threat posed  by the
site.   The  primary contaminants of concern
affecting the ground  water  are  organics
including pesticides.
SELECTED REMEDIAL ACTION:

The selected  remedial  action for this interim
remedy includes extending municipal water lines
and connecting all residences with private wells
and the church to the municipal  water supply;
and  implementing   institutional   controls,
including ground water use restrictions.  The
estimated capital cost for this remedial action is
$106,000.  There are no O&M costs associated
with this remedial action.

PERFORMANCE STANDARDS  OR GOALS:

Clean-up  levels for ground  water will  be
addressed in the final remedy.

INSTITUTIONAL CONTROLS:

Institutional  controls will  be implemented  to
prevent consumption of contaminated ground
water.

                                  September 30,1991
 SITE HISTORY/DESCRIPTION:

 The Interstate Lead (ILCO) site consists of seven
 subsites located in and around the City of Leeds,
 Jefferson County, Alabama. The site includes an
 8.5-acre  active lead smelting facility  and its
 parking lot, a service station; a  manufacturing
 company;  a church parking  lot; a  l.4-acre
 residential property; a municipal landfill;  and a
 restaurant.   Land  use  in  the area is mixed
 industrial and residential. Parts of the ILCO site
 overlie the Fort Payne  Chert and  Ordovician
 Undifferentiated  aquifers, both  of which  are
 sources of drinking water for the City of Leeds.
 Since 1970, ILCO has manufactured refined lead
 alloys through the  smelting and  refining of
 lead-bearing scrap  metals including lead-acid
 automobile batteries. The resultant furnace slag
 has been disposed of at the seven subsites  along
 with battery casings and wastewater treatment
 sludge.  From 1973 to 1984, ILCO stored furnace
 slag,  battery chips, and wastewater treatment
 sludge in piles at the main facility and also used
 these  wastes as fill  material at  the other site
 areas. Additionally, some waste was disposed of
 at the municipal landfill. State investigations in
 1983 and 1984, and a number of subsequent EPA
 investigations, identified metal contamination in
 onsite soil, sediment,  ground  water,  surface
 water, and  air.   In 1984, EPA  conducted an
 emergency removal action at the church subsite,
and removed and disposed of approximately
 5,000  cubic yards of waste material and soil
offsite. This ROD provides  a final remedy for
 soil contamination at all of the subsites except
the main facility portion of subsite  #1, and
ground  water  contamination  at four of the
subsites as operable unit 1.  Future RODs will
address sediment, ground water, and  surface
water contamination at the main facility.   The
primary contaminants of concern affecting the
soil, sediment,  debris, and  ground water are
metals including arsenic, chromium, and lead.
 SELECTED REMEDIAL ACTION:

 The selected source control remedial action for
 the ILCO parking lot and the restaurant subsites
 includes excavating soil and sediment with lead
 concentrations  exceeding  300 mg/kg and 50
 mg/kg, respectively; controlling dust with water
 spray   during   excavation   and   removal;
 dewatering  the   sediment;   treating   the
 contaminated material onsite using solidification
 and stabilization; replacing the treated soil into
 the excavated areas in compliance with  RCRA
 requirements, and capping the areas; removing
 battery   casings  and   other  debris   with
 solidification of battery casing  material,  and
 onsite disposal of solidified material and offsite
 disposal of other debris;  and conducting air
 monitoring.    The  selected  source  control
 remedial action  for  the  service station,  the
 manufacturing    company,   the   residential
 property,  and   church   subsites   includes
 excavating  and  treating soil using solidification

 soil, or disposing of  treated materials in  the
 original excavated areas with implementation of
 institutional controls including deed restrictions;
 removal of  sediment exceeding 50 mg/kg lead,
 dewatering, and  treating  the  sediment  along
 with the soil; and air monitoring.  The selected
 source control remedial action for the municipal
 landfill includes constructing a multi-layer cap
over soil contaminated with lead concentrations
exceeding 300 mg/kg; implementing institutional
controls  including land use  restrictions,  and
access restrictions; and ground water monitoring.

                                   August 29,1991
SITE HISTORY/DESCRIPTION:

The 8.6-acre Mallory Capacitor site is a former
electrical capacitor  manufacturing  facility in
Waynesboro, Wayne County, Tennessee.  Land
use in the area is mixed residential, commercial,
and industrial, with the Green River bordering
the site to the  east.  There are 54 private wells
located  within a 1-mile radius of the site that
draw on the Fort Payne Formation  aquifer for
ground  water.  The Mallory Capacitor Company
was operated from 1969 to 1979 by Duracell, and
from  1979  to  1984 by Emhart Industries to
manufacture electrical capacitors onsite using
TCE as part of the process.  Process  liquid
wastes  were stored in underground storage
tanks onsite. From 1976 to 1980, clean-up actions
were  implemented  by  Emhart  to remove
PCB-contaminated   materials  from  process
equipment  within  the  manufacturing facility.
These  actions  also  included  removing  the
underground storage tank adjacent to the plant
and associated surrounding PCB-contaminated
soil. In 1984,  routine  TCE still bottom testing
revealed PCB-containing  still  bottoms.    The
facility was subsequently shut down because of
unsafe working conditions. Subsequent studies
revealed significant levels of PCBs on portions of
the plant structure, in process equipment, and in
soil; and   elevated  VOC levels  also   were
identified in ground water.  This ROD addresses
contaminated ground water as  a final remedy.
The primary contaminants of concern affecting
the ground  water are VOCs including 1,2-DCE
and TCE; and other organics including PCBs.
SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
ground  water pumping and onsite  treatment
using air stripping; removing precipitates using
filtration and carbon adsorption, followed  by
onsite discharge to the Green River  or offsite
discharge to a POTW; monitoring ground water;
conducting additional investigations to assess the
extent of offsite ground water contamination and
the impact to surface waters; and implementing
institutional controls including deed and ground
water use restrictions.  If it is determined that,
based on site conditions, PCBs are resistant to
removal  by pumping and that  ground  water
cannot be restored  to beneficial use for any or all
of the  contaminants,  all  of  the   following
long-term management  measures  may  be
implemented: employing engineering controls as
containment   measures;   invoking
chemical-specific  ARAR waivers for aquifer
cleanup  based  on  technical  impracticability;
implementing institutional controls  to restrict
access  to the aquifer;  reevaluating  remedial
technologies for ground  water remediation; and
continued monitoring of specified wells.  The
estimated present  worth cost for this remedial
action is $3,005,000.

PERFORMANCE STANDARDS  OR GOALS:

Chemical-specific ground water clean-up goals
are based on SDWA MCLs, and  include PCBs
0.5 ug/1, TCE 5 mg/1, and cis- and trans-l,2-DCE
70 ug and 100 ug/1, respectively.

                                  September 30,1991
SITE HISTORY/DESCRIPTION:

The 280-acre Maxey Rats Nuclear Disposal site
is  an  inactive  low-level  radioactive  waste
disposal facility in Fleming  County, Kentucky.
Land  use  in  the   area  is  predominantly
agricultural  and  residential,  with   mixed
woodlands surrounding the site.  The estimated
663 people who reside within 2.5 miles of the
site use the public water supply for  drinking
purposes.    From  1962  to  1977,  Nuclear
Engineering Company, Inc. {NECO), operated a
solid  by-product source, and special  nuclear
material disposal facility under a license with the
State.   During  this  time, NECO disposed  of
approximately 4,750,000 cubic feet of low-level
radioactive waste in an approximately 45-acre
area, designated as the "Restricted Area".  The
majority of the waste was disposed of in unlined
trenches,  but  concrete  capped  "hot  wells"
consisting of coated steel pipe, tile, or concrete
also were  used for  disposal of small-volume
wastes with high-specific activity.  The  wastes
were deposited in 52 disposal trenches within 27
acres  of the Restricted Area in both solid and
solidified-liquid  form  and  were   both
containerized and deposited loosely.   Several
State investigations in the 1970*5 revealed that
leachate contaminated  with  tritium and other
radioactive substances was migrating from the
disposal trenches to unrestricted areas. In 1977,
the State ordered NECO to cease the receipt and
burial of radioactive waste. From 1973 to 1986,
an evaporator was operated onsite as a means of
managing the large volume of water infiltrating
the disposal  trenches  as well as  wastewater
generated by onsite activities. The  evaporator
processed more than 6,000,000 gallons of liquids,
leaving behind  evaporatory  concentrates that
were stored in  onsite above-ground  tanks, and
eventually disposed of in an onsite  trench.  In
1979,   the  State  initiated  stabilization  and
maintenance activities including installing a
temporary PVC cover over the disposal trenches
to minimize rainfall infiltration.  In 1988, EPA
conducted a two-phase removal action to handle
the threat posed by 11  onsite 20,000-gallon tanks
of questionable structural integrity located  in a
tank  farm building.    Phase I  consisted of
installing a heater in the tank farm building to
prevent  the  freezing  and rupturing of tank
valves and fittings.   Phase  II  consisted of
solidifying  approximately  286,000  gallons of
radioactive liquids stored  in the 11 tanks  and
water on the floor of the tank farm building.
The solidified blocks will be disposed of onsite
in  a  newly  constructed  trench.    This ROD
addresses final  remediation of soil, debris, and
associated leachate.  The primary contaminants
of concern affecting the soil and debris are VOCs
including benzene,  TCE,  and toluene; metals
including arsenic and  lead;  and  radioactive
materials.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
extracting, solidifying, and disposing onsite of
approximately  3,000,000  gallons   of  trench
leachate;  demolishing and disposing  of  site
structures onsite; excavating additional disposal
trenches for disposal of site debris and solidified
leachate;  installing  an  approximately  50-acre
initial cap consisting of a clay and synthetic liner
after disposal of solidified leachate and debris in
the  trenches;   maintaining and   periodically
replacing the initial cap synthetic liner as needed
every 20  to 25 years; re-contouring the capped
disposal  area  as  needed to  enhance   the
management of surface water run-on and run-
off; temporarily storing any additional wastes
generated after constructing the initial cap onsite,
followed  by solidification and onsite disposal of
those  wastes in a newly constructed  disposal
trench; installing a ground  water flow barrier, if
necessary; installing an infiltration monitoring

                                      May 29,1991
SITE HISTORY/DESCRIPTION:

The 7-acre Medley Farms site is a former waste
disposal area located on a private farm used as
pasture 6 miles  south  of  Gaffney, Cherokee
County, South Carolina.  Land use in the area is
predominantly agricultural and light residential,
and six private wells are within a 1-mile radius
of the site. The site overlies a shallow saprolitic
and a deeper bedrock aquifer.  All residents in
the near vicinity of the site are connected to the
public water distribution system.  From 1973 to
1976,  the site was used for disposal of drummed
and other waste materials.   In 1983, the State
identified  approximately  2,000  deteriorating
55-gallon drums and numerous plastic containers
scattered throughout the site. Other observations
included a chemical  odor  in  the air, several
excavation pits containing discolored water and
drums, and  stressed  vegetation.  Several State
and EPA  studies identified VOCs and other
organics in onsite soil. In 1983, EPA removed
5,383   fifty-five-gallon  and   fifteen-gallon
containers; disposed  of empty drums  offsite;
bulked 24,000 gallons of liquid wastes, with
offsite incineration of the wastes; crushed and
disposed of the empty drums offsite; excavated
and  disposed  of  2,132   cubic   yards   of
contaminated soil  offsite; drained 70,000 gallons
of water from six small lagoons, followed by
treatment  using   a  pressurized sand/gravel/
activated  carbon  filtration  system  to  remove
organic contaminants; and backfilled the lagoons
with clean soil. Following this removal  action,
EPA conducted a geological study to determine
the potential  for ground  water contamination.
Subsequent EPA studies identified VOCs in both
soil and ground water. This ROD addresses soil
and ground  water contamination  as  a final
remedy. The primary contaminants of concern
affecting the soil and  ground water  are VOCs
including  benzene, PCE, and TCE; and other
organics including pesticides and PCBs.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating contaminated  soil onsite using in-situ
vapor extraction, and controlling air emissions
using  carbon  adsorption;   regenerating   or
disposing of  the spent carbon; pumping and
treatment of contaminated ground water using
precipitation, flocculation, ion exchange, or some
other method of metal  removal if  necessary,
followed by air stripping; discharging the treated
water onsite to surface water; and  monitoring
ground water, surface water, soil, and sediment.
If the ground water treatment system cannot
meet  the   specified   remediation  goals,
contingency  measures  and  goals  will   be
implemented  including engineering controls or
institutional controls, invoking chemical-specific
ARAR  waivers,  or  reevaluating   remedial
technologies for ground water restoration. The
estimated present worth cost for  this remedial
action is $2,404,000, which includes an annual
O&M cost of $1,451,000 for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific  soil  clean-up  goals  were
derived  from  calculations based on leachate
modeling, and include PCE  1,600 ug/kg and
TCE 500 ug/kg. Chemical-specific ground water
clean-up goals are based on SDWA MCLs and
proposed MCLs, and include benzene 5 ug/1
(MCL),  PCE 5 ug/1 (MCL),  and TCE 5 ug/1
(MCL).

INSTITUTIONAL CONTROLS:

Ground   water  use   restrictions   may  be
implemented to restrict access  to those portions
of  the  aquifer  which  may  remain  above
health-based levels.

                                  December 7,1990
SITE HISTORY/DESCRIPTION:

The 75-acre Monsanto site is a former industrial
plant located 3  miles  southeast  of Augusta,
Georgia.  Land use in the area is predominantly
industrial,  with  a  wetland  area  located
approximately 4,570  feet from the site.   In
addition, the site is approximately 3 miles from
the Savannah River, an important source of
water for the Augusta area.  The plant  began
operations  in 1962.   From 1966 to  1974,
approximately 1,500 pounds of arsenic were
placed in two onsite landfills. The landfills were
covered with  soil, crowned with gravel, seeded
with grass, and  closed  in  1971  and  1977,
respectively.   Ground  water investigations
conducted  in 1979  and  1980 by Monsanto
identified arsenic in the surficial  aquifer in
excess of the Federal MCL. In 1983, Monsanto,
through a State action, excavated the materials in
the landfills and disposed of them offsite.  Soil
samples  collected  from  the  bottom of  the
excavated area did not  exceed the EP toxicity
standard  for arsenic. This final ROD addresses
ground  water contamination.   The  primary
contaminant of concern affecting  the ground
water is arsenic, a metal.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
monitoring ground water to evaluate compliance
with Ground Water Protection Achievement
Levels  (GPALs);  pumping and   discharging
ground water to an offsite POTW, in the event
that  non-compliance   with  GPALs  occurs;
monitoring  ground water for 2 years following
EPA's  acceptance that  the  MCL  has  been
attained.  The estimated present worth cost for
this remedial action is $600,000.
PERFORMANCE STANDARDS OR GOALS:

The chemical-specific and GPAL ground water
clean-up goal for arsenic is 0.05 mg/1 based on
SDWA MCLs.

 SITE HISTORY/DESCRIPTION:

 The Oak Ridge Reservation (ORR) (USDOE) site
 is an inactive uranium recovery landfill in Oak
 Ridge, Anderson County, Tennessee. The United
 Nuclear Corporation (UNO disposal site, which
 comprises operable unit  2  (OU2),  is  one of
 several hundred waste disposal sites or areas of
 contamination  at  the  ORR  site   requiring
 Superfund remedial action. From 1982 to 1984,
 the  1.3-acre  disposal site  received  11,000
 55-gallon drums of cement-fixed sludge, 18,000
 drums of contaminated soil,  and 288 wooden
 boxes of contaminated building and process
 equipment   demolition  debris  from   the
 decommissioned UNC uranium recovery facility
 in Wood River Junction,  Rhode Island.  The
 wastes were placed in 5- to 50-foot deep pits and
 covered  with  polyvinyl  chloride  sheeting.
 Although  some  drums  and  boxes  have
 deteriorated, rusted, or split open, investigations
 show that migration of contaminants to soil and
 ground water has not yet occurred. This ROD
 addresses the drummed soil, sludge, and debris
 to prevent future ground water contamination.
 Subsequent RODs are planned to fully address
 the principal threats posed by the ORR site. The
 primary contaminants  of concern affecting  the
 soil, sludge, and debris are nitrite, an inorganic;
 and strontium-90, a radioactive material.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
clearing and grubbing sparse vegetation; placing
a multi-layer cover over the drums, soil, sludge,
and debris; revegetating the area and backfilling
over the UNC waste with additional  soil; and
monitoring  ground  water.    The  estimated
present worth cost for this remedial  action is
$1,467,500, which includes an annual O&M cost
of $93,600 for year 0-1 and $69,800 for years 2-30.
PERFORMANCE STANDARDS OR GOALS:

The  selected  remedy  will  prevent  future
contamination of ground  water  from landfill
wastes.  Accordingly, the remedy will meet the
SDWA MCL for nitrate 10 mg/1 at downgradient
wells and meet a 10"6 risk level for strontium-90.

 waste disposal sites or areas of contamination at
 the  ORR  site requiring  Superfund  remedial
 action.  The site  occupies the upper reaches of
 East Fork  Poplar Creek (EFPC) in Bear Creek
 Valley.  From 1940 to the present, the Y-12 plant
 has  been  used   to produce nuclear  weapons
 components.  From 1955  to 1963, mercury was
 used  in  a column-exchange process to separate
 lithium  isotopes.   Mercury spills  from this
 process  resulted   in  mercury  and
 mercury-contaminated sediment being pumped
 from  the  basements of  buildings into  three
 concrete sedimentation tanks connected to storm
 sewers, which discharge to EFPC. Testing of the
 three concrete  tanks  showed  that  the tank
 sediment  contained  mercury,   and   that
 contaminated waste is still being discharged into
 two of the three tanks. This ROD focuses on the
 contaminated  sediment in  the  sedimentation
 tanks as an interim  action.  Future RODs will
 address  principal   threats  posed  by  plant
 conditions including eliminating mercury from
 the  storm sewer  system.    The  primary
 contaminants of concern affecting the sediment
 are mercury, a metal; and radioactive materials.

 SELECTED REMEDIAL ACTION:
The selected interim remedial action for this site
includes   removing   mercury-contaminated
sediment, liquids, solids, oils, and oily water
from tanks, followed by offsite treatment and
disposal; stabilizing mixed wastes from one of
the tanks, followed by onsite disposal; screening
the wastewater removed  from the tanks  for
hazardous and radiological contamination prior
to  sediment   removal,  followed  by  onsite
treatment of the wastewater; solidifying mixed
wastes,  followed  by  onsite  storage;  and
monitoring ground water and sediment.  The
estimated capital cost for this remedial action is

SITE HISTORY/DESCRIPTION:

The  Oak  Ridge Reservation (ORR)  (USDOE)
(Operable Unit 4) site is a former uranium
isotope processing subsite in Oak Ridge, Roan
County, Tennessee.   The 1,700-acre K-25 site,
which comprises operable unit 4 (OU4), is one of
several hundred waste disposal sites or areas of
contamination  at  the  ORR  site  requiring
Superfund remedial action. Land use in the area
is predominantly  residential.   Three  drum
storage areas are located in the  northeastern
portion of the site and consist of two adjacent
asphalt pads covering six acres on the north side
of Mitchell Branch, a small stream.  A curb
surrounding the pads directs water to a catch
basin for each yard, all of which discharge to
Mitchell Branch. Built in the 1940's, the K-25 site
was  used  to  separate uranium  isotopes by
gaseous diffusion with placement of resulting
wastes and  sludge in collection ponds.  The
storage yards were constructed to  temporarily
store sludge that was removed, stabilized, and
drummed during closure of the collection ponds
from 1987 to 1989. The storage yards contain
36,000 ninety-gallon drums of stabilized sludge,
29,000 ninety-gallon drums of raw sludge, and
16,000  gallons   of   raw  sludge  in  tanks,
contaminated  with   mixed   radioactive  and
hazardous wastes.  The drums have started to
deteriorate and develop pin hole leaks resulting
in the release of small quantities of liquids to the
pads.  In  addition,   depressions  have been
observed  in the asphalt pads causing stacked
drums to lean. This ROD addresses the sludge
stored at the storage yards as an interim action
to  prevent  or  mitigate  releases   to   the
environment.  Future RODs will address sludge
remediation   and  disposal.    The  primary
contaminants of concern affecting the sludge are
metals and radioactive materials.
SELECTED REMEDIAL ACTION:

The  selected remedial action for this interim
remedy includes  eliminating  free  liquids  in
sludge through filter press, thermal drying, or
similar methods; repacking dry sludge, followed
by onsite storage of containers in existing or new
indoor  facilities  awaiting  remediation  and
disposal; and processing liquids removed from
the sludge through existing treatment facilities.
The  estimated  capital cost  for  this remedial
action is $69,000,000, with an annual O&M cost
of $400,000. This interim remedy is expected to

 storm drainage  wells.   PPC  began  onsite
 operations as a processor and broker of waste oil
 in 1958.  Several tanks  were located  in a tank
 farm  area bounded on  the east and north  by
 several  large  areas of standing water, which
 served as a culvert drainage system.  Sludge
 generated during oil refinery  processes was
 disposed of onsite in unlined disposal pits.  In
 1970,  a major rainfall caused  the onsite disposal
 pit to overflow, producing an oil slick on the
 lakes  of a nearby trailer park. Subsequently, all
 disposal  pits were filled in, but it is suspected
 that sludge  was  mixed with  clean  fill and
 returned to the pit or spread over the property.
 Drainage at the site was then upgraded to a
 french drain system and drainage wells, which
 relieved  flooding  of  the  site and  permitted
 flushing  of former disposal  pit contamination
 into the ground water.  In 1971, PPC ended all
 onsite refining operations.  The property was
 subsequently used as a storage and distribution
 facility.  In 1979, at the  request of the County,
PPC cleaned  up portions of the site including
 two oil-soaked areas. In  1983, the State required
PPC to remove additional waste oils and submit
a  detailed  site  sampling  plan.   Subsequent
sampling identified that the ground water had
been contaminated by oils,  VOCs, petroleum
hydrocarbons, and inorganic compounds.   In
addition, a State investigation conducted in 1984
 revealed that 20,000 to 60,000 gallons of free oil
 were present in a ground water plume centered
 on the tank farm area and that fluctuations in
 the water table had led to soil contamination by
 these oils. In response to an 1985 Administrative
 Order (AO), PPC emptied, cleaned, and rendered
 inoperable all tanks; tested all oil, water, and
 sludge before disposal or recycling; removed and
 encapsulated asbestos from a boiler house; and
 transported 262 drums of sludge offsite. In 1985,
 the State installed a free product recovery system
 to recover oil floating  under  the  site,  and  a
 concrete pit was installed in an onsite warehouse
 to contain free oil seeping up through the floor.
 This  ROD  addresses the first operable unit
 (OU1), enhancement of the free product recovery
 system as an interim remedy.   A future ROD
 will  address source control and ground water
 treatment. The primary contaminants of concern
 affecting the site are metals including chromium
 and lead; and oils.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for  this site includes
 abandoning the damaged monitoring wells that
 remain onsite; abandoning the storm drainage
 wells onsite, which put the Biscayne aquifer at
 risk; monitoring private wells  in  the  vicinity;
 enhancing  the present  free  product recovery
 system to remove a larger volume of oil and to
 contain the contaminated ground water plume;
 and disposing of waste oil offsite at an approved
 refinery.   The estimated capital cost  for this
 remedial action is $660,000, with an estimated
 O&M cost of $83,000.

 PERFORMANCE STANDARDS OR GOALS:

This interim remedy will enhance  the free
product recovery system and reduce the threat of
contaminant migration  into municipal  wells;
therefore, clean-up goals  were not provided.

                                  December 19,1990
 SITE HISTORY/DESCRIPTION:

 The 253-acre  Sangamo/Twelve-Mile/Hartwell
 PCB site consists of seven separate disposal areas
 in Pickens County, South Carolina. These areas
 consist of the Sangamo Plant area and six private
 disposal areas located  offsite of the Sangamo
 Plant, which are  designated as the Breazeale,
 Nix, Dodgens, Cross Roads, John Trotter, and
 Welborn areas.   Land in  the  general area is
 predominantly forested, and there are several
 nearby  lakes  and  streams  including  Lake
 Hartwell and  the Twelve-Mile  Creek basin.
 Since   1955,  Sangamo  Weston,  Inc.,   has
 manufactured  electrolytic,  mica,  and  power
 factor capacitors.  PCBs were used as dielectric
 fluid in power factor capacitors. Prior to 1972,
 waste materials containing PCBs were land filled
 in   the  seven   disposal   areas.     These
 PCB-contaminated materials  included  scrap
 capacitors and aluminum hydroxide sludge from
 an onsite wastewater treatment plant.   In  the
 mid-1970's,  State  and  Federal  environmental
 monitoring programs led to the  detection of
 PCBs in the sediment of Lake  Hartwell, in its
 tributaries, and in  the soil of Sangamo Weston's
 dump sites.  In addition, PCBs were detected in
 fish samples at two  sites in the Twelve-Mile
 Creek area of Lake Hartwell, In 1980, Sangamo
 Weston, Inc., removed  a total  of 17,711 cubic
 yards of PCB-contaminated soil and debris from
 the Nix and Dodgens areas, and disposed of it in
 a landfill on the Sangamo Plant property.  In
 1986,  a  geotextile liner  and  soil cap  were
 installed as an interim measure to retard  the
 migration of  PCB contamination from   the
 Breazeale site.   In 1989, EPA removed offsite
7,285 tons of PCB-contaminated soil and debris
from the Sangamo  Plant area to a RCRA landfill,
and 6,684 capacitors  were taken to an offsite
incinerator. This ROD addresses the first of two
 operable units, and provides for remediation of
 the ground water and source  contamination at
 the seven disposal areas.  A  future ROD will
 address the contamination of the  Twelve-Mile
 Creek basin and Lake Hartwell.  The primary
 contaminants of  concern affecting the  soil,
 sludge,  debris,  and ground water are VOCs
 including PCE  and TCE; and other organics
 including PCBs.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 excavating materials contaminated  with greater
 than 1 mg/kg of PCBs at the Nix and Welborn
 areas; excavating materials contaminated with
 greater than 25 mg/kg of PCBs at the Sangamo
 Plant area; excavating materials contaminated
 with greater  than  10  mg/kg of PCBs  at the
 Breazeale, Dodgens,  Cross Roads, and John
 Trotter   areas;   transporting   the  excavated
 materials to the  Sangamo Plant area for staging
 and  treatment;  treating  onsite all excavated
 materials using  thermal  desorption technology
 and  carbon adsorption   to control off-gases;
 placing  the treated soil  within the Plant area;
 filling each of the private areas with 2 feet of
 clean fill where contaminated materials with
 PCBs greater than 1 mg/kg remain, specifically
 the Trotter, Dodgens, Breazeale, and  Cross Roads
 areas;  ground  water  pumping  and   onsite
 treatment at  the Dodgens,  Breazeale,  Cross
 Roads,  and  Sangamo Plant  areas using air
 stripping  and/or  carbon adsorption;   and
discharging the  treated water onsite to  surface
 water. The estimated present worth cost for this
remedial action  ranges   from  $47,900,000 to
$63,300,000 depending on aquifer characteristics
and the  volume of excavated solids. No O&M
costs were provided for this remedial action.

                                    March  27,1991
SITE HISTORY/DESCRIPTION:

The 42-acre Sherwood Medical Industries (SMI)
site is an active medical supply manufacturing
facility just outside the city limits of Deland,
Volusia County, Florida. Land use in the area is
commercial and residential. Lake Miller is along
the western boundary, and a wooded  swampy
area is located  to  the south of the site.   The
underlying   Floridan   aquifer,  which   is
restrictively  connected   to  the  contaminated
surficial aquifer, is the drinking water source for
local residents.  From 1959 to present, SMI has
used the site for manufacturing medical supplies,
primarily hypodermic needles.   From 1971  to
1980, SMI disposed of approximately 2 tons  of
liquid  and  sludge waste  into two  unlined
percolation  ponds onsite.  At that  time, solids
were removed from the ponds and placed into
onsite, unlined impoundments.  From 1980  to
1982,   SMI   analyzed  the   contents  of  the
impoundments and disposed of the wastes in an
offsite  landfill.    Initial  site  investigations
conducted by SMI and  the State identified
ground water contamination in onsite wells. In
1987,  the State requested that  SMI  perform
additional investigations to determine the nature
and extent of ground water contamination, and
to evaluate  the need  to  implement interim
remedial  measures.  Based  on  the  observed
onsite contamination of the Floridan Aquifer, the
State required SMI to conduct extensive ground
water testing and monitoring, and to provide
bottled water to an affected residence.  In  1990,
the State approved SMI's  design  work  plan,
which outlined further  interim measures to be
conducted at the site including installation of a
ground water pump and treat system. This ROD
addresses an interim remedy for the surficial
aquifer to prevent the contaminant plume from
spreading offsite and migrating vertically  into
the Floridan aquifer. Future RODs will  fully
address the principal  threats  posed by the
conditions at the site. The primary contaminants
of concern affecting the ground water are VOCs
including PCE and TCE.

SELECTED REMEDIAL ACTION:

The  selected  remedial action  for this  interim
remedy includes installing a system of recovery
wells in the onsite surficial aquifer; and pumping
and  treatment of contaminated  ground water
using air stripping, followed by onsite discharge
of the treated  water to  Lake  Miller.   The
estimated capital cost for this interim remedial
action is $400,000, with an annual O&M cost of
$35,000.

PERFORMANCE STANDARDS OR GOALS:

Treated ground  water will meet all Federal and
state water quality standards for discharge to
surface water.  Final clean-up  levels will be
addressed in a future ROD.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 500-acre Smith's  Farm  Brooks  site is  a
former hazardous waste disposal area located in
Brooks, Bullitt County, Kentucky.  The  site is
bordered on the north, east, and west by forested
hills and on the south by a residential area. The
site includes a  37.5-acre  landfill that,  until
recently, was permitted by the State for the
disposal of solid waste. The site also includes an
80-acre area upgradient of the permitted landfill
on a mile-long ridge between two intermittent
creeks where the unpermitted disposal of drums
containing hazardous  waste occurred over  a
20-year period. This area has been divided into
two areas known as Area A and Area B,  As a
result of EPA investigations in 1984 that revealed
chemicals leaking from drums, EPA removed
6,000   drums  of  surface  wastes, excavated
contaminated  soil,   and  implemented  site
stabilization and  erosion prevention measures.
A  1989 ROD addressed source control  in the
80-acre  area  through  thermal   destruction.
Investigations during  the RD revealed  lower
levels  of PCBs and a lower volume of soil
requiring treatment than what was previously
estimated in the RI, making incineration less
practical. This ROD amends the 1989 ROD and
provides source control in the 80-acre area using
chemical  treatment,  rather   than   thermal
treatment.  A second operable unit  will address
remaining potential threats associated with the
landfill, deep ground water aquifers, and other
suspected areas of drum disposal.  The primary
contaminants  of  concern  affecting  the soil,
sediment, and debris are organics  including
PCBs and PAHs, and metals including lead.

SELECTED REMEDIAL ACTION:

The amended remedial action for  this  site
includes excavating 16,000 cubic yards of
contaminated soil and excavating contaminated
stream sediment in Area B, as defined in the
RI/FS; treating Area B soil and sediment onsite
by a chemical process, possibly dechlorination or
hydrocarbon removal  using APEG  or BEST,
respectively, and  by a  solidification/fixation
process; overpacking debris from Area B and
disposing  of the  overpacked debris and all
treated soil and sediment from Area B onsite
within Area A; consolidating the contaminated
soil, sediment, and debris from peripheral areas
of Area A  into  Area A; recontouring Area A;
constructing and maintaining  retaining walls,
surface run-on/run-off control systems, and  a
leachate collection system in Area A, with onsite
or offsite treatment and disposal of leachate;
capping Area A with a RCRA cap after all
material from Area A and B have been disposed
of in  Area A;  monitoring  ground water; and
implementing institutional  controls  including
land use restrictions, and site access restrictions.
The estimated  present worth  cost for this
remedial action ranges  from  $22,000,000  to
$25,000,000,  based on  the  treatment selected.
O&M costs were not provided.

PERFORMANCE STANDARDS OR GOALS:

Action levels  for contaminated  soil and/or
sediment were determined  based on an excess
lifetime cancer risk of 10"5, with the exception of
lead, which was based on an HI<1. Chemical-
specific goals for soil include  PAHs 2 mg/kg
and lead 500 mg/kg; and  for sediment PAHs
5 mg/kg and PCBs 2 mg/kg.

INSTITUTIONAL CONTROLS:

Land use restrictions will be implemented onsite
to limit further site use.

 SITE HISTORY/DESCRIPTION:
 SELECTED REMEDIAL ACTION:
 The 349-acre Tri-City Industrial Disposal site is
 an inactive industrial  waste landfill located in
 Brooks, Bullitt County, Kentucky.  Land use in
 the  area  is  predominantly  agricultural  and
 residential. The estimated 300 people who reside
 within 1 mile of the site use ground water from
 a  thin  unconfined  limestone aquifer as their
 drinking  water  supply.    Ground  water
 discharges via several springs including the Cox
 and Klapper Springs.  From  1964  to 1967,
 Tri-City Industrial Services, Inc., used the site to
 dispose of  industrial  waste including  scrap
 lumber, fiberglass insulation materials, drummed
 liquid wastes, and bulk liquids that were poured
 onto the ground. In  1968, State officials reported
 that highly  volatile liquid  wastes  resembling
 paint thinners were disposed of onsite. The site
 was a  source of citizen complaints about  the
 condition  of the landfill, explosions, fires, and
 smoke  during  the  disposal operations.    A
 number of State and  EPA  investigations  that
 were  conducted  between  1965  and  1989
 identified contaminants including PCBs, phenols>
 metals, and various organic compounds in onsite
 soil, wastes, and residential  springs.  In 1988,
 EPA provided local  residents with an alternate
 water  supply, and  conducted an  emergency
 removal  action  to  excavate  and   remove
 approximately 165  drums  in generally  good
 condition, other crushed and empty  drums,
 metal containers, auto  parts, 400  gallons of free
 liquids, and  over 800 cubic  yards of suspected
 contaminated soil. This ROD addresses ground
 water contamination as operable unit 1  (OU1).
 Should  the  confirmatory   sampling  of soil,
 sediment,  and  air  conducted in OU1  reveal
 unacceptable levels of hazardous contaminants,
additional measures  may be necessary and will
be  implemented  as   OU2.    The  primary
contaminants of concern affecting the ground
water are VOCs including  PCE,  TCE, DCE,
toluene, and  vinyl chloride.
The selected remedial action for this site includes
installing a carbon adsorption system at the Cox
Spring; treating contaminated ground water
using  carbon adsorption and discharging  the
treated ground water to tributaries downstream
of the  springs; conducting a teachability test to
determine whether spent carbon is a hazardous
waste; regenerating, or treating and disposing of
spent  carbon  offsite;  continuing  to  provide
potable water to residents who previously used
contaminated ground  water  as potable water
until acceptable levels are reached; confirmatory
sampling of soil, sediment, and ambient air to
assess the effectiveness  of EPA's 1988 Emergency
Removal Action; long-term monitoring of ground
water,  surface  water,  sediment, and ecology;
implementing  a  worker  health  and  safety
program; and implementing institutional controls
including ground  water use  restrictions.  The
estimated present  worth cost for this  remedial
action  is $2,098,000, which includes an annual
O&M cost of $89,890 for years 0-1,  $70,686  for
years 2-3, and $66,330 for years 4-30.

PERFORMANCE STANDARDS OR GOALS:

                                 September 26,1991
 SITE HISTORY/DESCRIPTION:

 The 15,200-acre USA Anniston Army Depot site
 is an active equipment rework facility for the
 U.S.  Army in  Anniston,  Calhoun  County,
 Alabama. The site is divided into several areas
 including a southeast industrial area, which is
 the focus of this ROD.  Land use in the area is
 predominantly residential. An estimated 72,000
 residents in Calhoun  County use  Coldwater
 Springs, located 1.5  miles south of the site, as
 their  primary source of drinking water. The
 Army initially used the depot to store munitions,
 and subsequently, to overhaul and repair combat
 vehicles.   Various types of  liquid and solid
 hazardous  wastes  were generated, including
 electroplating  wastes  containing metals and
 organic  solvents  from cleaning  operations.
 Wastes were disposed  of in various landfills,
 trenches, disposal pits,  and lagoons located in
 the southeast industrial area and throughout the
 site. A number of EPA and State investigations
 have  revealed  contamination  by VOCs, other
 organic compounds, inorganics, and metals in
 the onsite ground water.  Between 1978 and
 1983,  several onsite actions were taken by the
 Army to remove contaminated sludge and soil.
 In  1990,  the  Army  completed  and  began
 operation  of  a ground water pumping and
 treatment  system.   This ROD  addresses an
 interim remedy for ground water contamination
beneath the southeast industrial area as the first
operable unit.  Future RODs may address further
contamination in the southeast industrial portion
of the site. The primary contaminants of concern
affecting the ground water are VOCs including
PCE and TCE; other organics including phenols;
and metals including chromium.

SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
continued  use  the  existing  ground   water
pumping and treatment system using air
stripping to remove VOCs, followed by charcoal
filtration to  remove phenols;  discharging the
treated ground water onsite to surface water;
and continued operation of the dewatering and
treatment system.  The estimated present worth
cost for this  remedial action is $945,000, which
includes an annual O&M cost  of $60,000.  The
capital cost is estimated at $895,000.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water goals will be
addressed in the final remedial action for the
site.

                                     June 25, 1991
SITE HISTORY/DESCRIPTION:

The 46.5-acre USAF Robins Air Force Base site is
a logistics  management and repair center for
aircraft, missiles, and support systems in Warner
Robins, Houston County, Georgia. The Zone 1
area, which includes a  45-acre inactive landfill
and a 1.5-acre sludge  lagoon is part  of  the
8,855-acre Robins Air Force Base.  Land use in
the area is  mixed residential and industrial. A
wetlands area borders  the site to the east; in
addition, part of the site lies within the 100-year
floodplain of the Ocmulgee River. From 1965 to
1978, an onsite landfill (Landfill No. 4) was used
for disposal of general refuse, and industrial and
hazardous wastes. From 1962 to 1978, the sludge
lagoon was used for disposal of wastewater
treatment plant sludge and other liquid wastes.
Types  of  wastes  generated  at  the  facility
included electroplating wastes, organic solvents
from cleaning operations, and  pesticides, all of
which  were disposed  of in  the  lagoon  and
landfill areas. Robins Air Force Base conducted
a study in 1982 to identify and assess onsite
hazardous  waste disposal practices.   Disposal
areas were grouped into eight zones based on
location and type of activity. Zone 1 has been
divided into three operable units (OUs).  This
ROD, which focuses on OU1,  addresses  the
remediation of Landfill No. 4  and the sludge
lagoon.     Subsequent   RODs  will  address
remediation of the neighboring  wetlands  and
surface waters (OU2), the ground  water adjacent
to Landfill No. 4, and the sludge lagoon (OUS).
The primary contaminants of concern  affecting
the  soil, sludge, and  ground water are VOCs
including PCE and TCE; and metals including
arsenic, chromium, and  lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating 15,000 cubic yards of soil in the sludge
lagoon  using in-situ  soil  vapor  extraction;
removing  volatile contaminants from  the  air
using condensation, distillation, and  carbon
adsorption; controlling and treating  landfill
leachate; renovating the landfill cover;  treating
the sludge lagoon to remove VOCs,  treating
metals  onsite in  the  sludge  lagoon using
solidification;  onsite pumping and treatment of
ground  water; diverting surface water near  the
sludge lagoon; conducting long-term soil testing;
and monitoring ground and surface water. The
estimated present worth cost for this remedial
action ranges from $9,430,000 to $24,000,000, with
an annual  O&M cost ranging from $321,400 to
$334,400, depending on the components of  the
landfill cap.

PERFORMANCE STANDARDS OR GOALS:

Contaminant-specific remediation goals have not
been established  for soil at  the sludge lagoon
because they are dependent on establishment of
ground water  goals, which will be developed in
a subsequent ROD.

                                     June 27,1991
SITE HISTORY/DESCRIPTION:

The 242-acre Velsicol Chemical site is a former
plant waste  landfill located near the City of
Toone, Hardeman County, Tennessee. Land use
in the area is predominantly agricultural with a
wetlands  area, 26  residences, and  numerous
creeks located  within 1  mile of the site.  In
addition,  part  of the site  overlies  a  surficial
aquifer that was used as a potable water supply
in  the  area.   From 1964  to  1973,  Velsicol
Chemical Corporation used the site to dispose of
industrial and chemical plant wastes.  Waste was
disposed of in trenches excavated on  27 acres of
the  property.  The site was  closed  in  1973
because  of  the  possibility of contaminated
ground  water migrating  offsite.  By late  1978,
State and  Federal investigations had  confirmed
ground  water contamination in private wells,
and a public water supply was provided in  early
1979. In 1980, a 35-acre low permeability clay
cap was placed over the disposal area to control
and minimize additional impacts from the site.
This  ROD  addresses  offsite  ground water
contamination,  as operable unit  1  and  will
prevent   additional   onsite   ground  water
contamination from migrating from the disposal
areas.   Future RODs will  address  other site
contamination  and   principal  threats,    The
primary contaminants of  concern affecting the
ground  water  are   VOCs  including carbon
tetrachloride, chloroform, toluene, and xylenes;
ar>d other organics including pesticides,

.SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
'^stalling extraction  wells onsite and offsite to
restore  the  contaminated  ground  water  to
acceptable drinking water standards;
constructing an onsite ground  water treatment
plant and treating contaminated ground water
using solids removal, air stripping, and final
ground water  polishing  prior to  discharge;
discharging the treated water onsite to nearby
surface water bodies;  treating off-gases with
carbon adsorption;  monitoring ground  water;
maintaining the ground water treatment system
and the disposal area cover; and implementing
institutional controls including deed and ground
water use restrictions.   The selected remedial
action is contingent upon the performance data
collected during  operation.   If  the  selected
remedy cannot  meet the specified remediation
goals,  contingency  measures  may  include
alternating  pumping  at  wells  to  eliminate
stagnation points;  pulse  pumping at wells to
allow  aquifer  equilibration   and  encourage
adsorbed contaminants to partition into ground
water; and installing additional  extraction wells
to  facilitate  or  accelerate cleanup  of  the
contaminant plume.  The estimated  present
worth cost for this remedial action is $11,644,000,
which includes an annual O&M  cost of $696,000.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water clean-up goals
are based on SDWA MCLs and  health-based
criteria,  and   include   carbon   tetrachloride
0.005 mg/1  (MCL), chloroform,  0.006  mg/l,
toluene 1  mg/l (MCL), and xylenes 10 mg/1
(MCL).

INSTITUTIONAL CONTROLS:

Deed restrictions will be established to identify
the presence, quantity, and  nature  of wastes in
the disposal area and ground water, and to limit
uses of both until remediation is complete.

                                  September 30,1991
SITE HISTORY/DESCRIPTION:

The 81-acre Wrigley Charcoal site is a former
multi-use industrial operations area in the town
of Wrigley, Hickman County, Tennessee.  Land
use in the area is industrial and residential, with
approximately 1,000 people residing within a
one-mile radius of the site.  From 1881 to 1985,
the site has been used mainly for pig iron and
wood  retorting/wood  distillation by-product
manufacturing. Additional  activities conducted
between 1978 and 1985 included usage of several
remaining onsite buildings for metals machining,
copper  recovery,  and  storage  of drummed
industrial wastes. Improper disposal procedures
have resulted in  soil,  sediment,  and  debris
contamination   by  semi-volatile   organic
compounds  in  coal-tars (mainly  PAHs  and
phenols), VOCs,  metals, and asbestos.   EPA
investigations have identified four major areas of
onsite contamination. These four areas  are as
follows:  the  35-acre Primary Site containing
coal-tar contaminants; the 3-acre Storage  Basin
area that also contains coal tar contaminants; the
40-acre Irrigation Field (including an abandoned
wastewater lagoon)  that was used for spray
irrigation (disposal)  and degradation  of PAH
and  phenolic  wastewaters; and  the  3.5-acre
Athletic Field, a field used by local residents,
which is filled with blast furnace slag and soil
derived from the Primary Site from 1938 to 1950.
The  Primary Site was an industrial production
facility for iron, charcoal, and wood distillation
products from 1888 to 1966.  The Primary Site
was  later used for metals machining, storage of
waste products,  and recovery of copper from
transformers.   The Storage Basin and Irrigation
Held were built  in  the late  1950's to  receive
wastewater from the Primary Site. In 1988, EPA
performed a removal activity, which stabilized
the site by  installing clay  backfilled  culverts
covered with  erosion control fabric;  installing
sheet piling to stabilize the banks; retaining the
tar pits; removing  8  cubic  yards of asbestos
material; solidifying approximately  130  cubic
yards of tar pit wastes, followed  by  offsite
incineration   of   the   solidified   material;
establishing a vegetative cover for  the tar pit
cover;  constructing a  spillway;  and  offsite
landfilling  of debris.   This  ROD  addresses
interim  remediation of remaining contaminated
soil, sediment, and  debris, and will reduce the
risks at  the Primary Site and Storage Basin by
eliminating the most imminent and substantial
threats while permanent solutions are developed
for the entire site.  Future RODs may address
remediation of the  contaminated  Primary Site
soil, tar pits and tar cubes, as well as the Storage
Basin; coal-tar wastes, friable asbestos-corrugated
roofing material (ACM),  and any onsite ground
water problems.   The  primary contaminants of
concern  affecting  the soil  are  VOCs;  other
organics including PAHs, and phenols; metals
including arsenic, chromium, and lead;  and
asbestos, an inorganic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating, stabilizing, and  disposing of offsite
approximately 15 cubic yards of metallic wastes
from the burn pit;  consolidating and securing
onsite approximately 120 drums of transformers;
excavating,   incinerating,   stabilizing,   and
disposing of  offsite 14 waste drums, 29  cubic
yards of process  tank sludge, and 122.5  cubic
yards of black coal  tar wastes located in three
separate  areas;  decontaminating  the  tanks;
excavating  and  disposing   of  visibly friable
asbestos material in the soil and buildings within
the Primary Site; re-engineering of the spillway
to  accommodate flood   waters;  sorting  and
disposing of site surface wastes and debris piles
(including  tar-cubes; pieces  of ACM, crushed
drums and metallic debris) offsite, or temporarily
consolidating these onsite for future remediation;

                                 December 31,1990
SITE HISTORY/DESCRIPTION:

The 20-acre Acme Solvent Reclaiming site is a
former industrial disposal site in Winnebago
County, Illinois.  Land use in the area is mixed
agricultural and residential. The site is bounded
by an active quarry to the north, farmland to the
south and east, and the Pagel's Pit Superfund
site to  the west.  An onsite stream, which is a
tributary of Kilbuck Creek, eventually drains into
the Rock River to the south. The site overlies
two aquifers, which are used by the estimated
400 residents who live within 2 miles of the site
as their drinking water supply.  From 1960 to
1973, Acme Solvent Reclaiming  disposed of
paints, oils,  and still bottoms onsite from its
solvent reclamation plant.  Wastes were dumped
into  depressions   created   from  previous
quarrying and landscaping operations,  and
empty  drums  also were  stored onsite.  State
investigations in 1981 identified elevated levels
of chlorinated organic  compounds in  ground
water. A 1985 ROD provided for excavation and
onsite  incineration of  26,000  cubic yards of
contaminated soil and sludge,  supplying home
carbon treatment units  to affected residences,
and further study of ground water and bedrock.
During illegal removal actions taken by PRPs in
1986, 40,000  tons  of  soil  and  sludge  were
removed from the site.  A 4,000-ton waste pile
and  2  tanks  containing contaminated liquids
remain onsite, and since then an additional 2,000
tons of onsite contaminated soil and sludge has
been discovered. This ROD will address waste
areas  remaining  after  the  1986  removal,
including soil, bedrock, and ground water, as
part of operable unit 2  (OU2).  A future ROD
will  address  an   area   of  ground  water
contamination  between  the  Acme  Solvent
Reclaiming and Pagel's  Pit sites as OU3.  The
primary contaminants of concern  affecting the
soil, sludge,  and  ground  water are  VOCs
including benzene, PCE, TCE, and xylenes; other
organics including PCBs; and metals including
arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and treating 6,000 tons of soil and
sludge  from  two  waste areas using  low-
temperature thermal stripping; treating residuals
using solidification,  if necessary, followed by
onsite or offsite disposal; treating the remaining
contaminated soil and possibly bedrock using
soil/bedrock vapor extraction; consolidating the
remaining contaminated soil onsite  with any
treatment  residuals,  followed  by  capping;
incinerating offsite 8,000 gallons of liquids and
sludge from two remaining tanks, and disposing
of the tanks offsite; providing an alternate water
supply to residents with contaminated wells;
pumping  and  onsite  treatment  of  VOC-
contaminated ground water, with discharge to
surface water; monitoring ground water; and
implementing  institutional controls  including
deed and ground water  use and restrictions.
The  estimated present  worth  cost  for  this
remedial action  ranges  from  $14,633,000 to
$16,233,000, which includes an annual O&M cost
of $908,400.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific clean-up goals for soil are
based on a lifetime excess cancer risk level of
1 x 10"5.    All  waste  area  soil  exceeding
PCBs 10 mg/kg must be excavated and treated.
In addition, all soil exceeding 10 mg/kg above
background  levels  using a  photoionization
device will be excavated. Any soil remaining
after excavation and residuals landfilled onsite
must  meet  the site-specific  VOC clean-up
standards   including   benzene 69 ug/kg,
TCE 140 ug/kg,  and  PCE 1,200 ug/kg.

                                  December 28,1990
SITE HISTORY/DESCRIPTION:

The 95-acre Allied Chemical and Ironton Coke
site is composed of a former coke plant and an
operating tar plant in Ironton, Lawrence County,
Ohio.  The site is located within  a coal mining
region,  and   surrounding   land   use   is
predominantly industrial and residential.  The
Ohio River, a source of drinking water for the
city of Ironton, lies approximately 500 feet to the
west of the tar plant. Onsite lagoons lie within
the 100-year floodplain of the Ohio River, with
portions of the lagoons inundated sufficiently to
maintain  wetlands  vegetation.    From
approximately 1920 to the late 1960's, wastewater
and solid wastes including coke and coal fines,
tank car sludge, boiler ash, and weak ammonia
liquor were discharged into swampy areas east
of the Coke Plant, which are adjacent to Ice
Creek, a tributary to the Ohio River. From the
early 1970's until the coke plant closed in 1982,
a series of four lagoons in the eastern area of the
plant were used to treat process wastewaters,
stormwater run-off, and waste sludge; and a fifth
lagoon was used to dispose of solid waste.  Tar
plant operations began onsite in 1945.  Types of
wastes generated included anthracene residues
and  salts, coal tar pitch scrap,  and  phthalic
anhydride  residues,  which were disposed  of
onsite in the Goldcamp Disposal Area, a former
sand  pit adjoining the  tar  plant.   Extensive
studies  and  onsite  investigations  identified
contamination in onsite soil in the Coke Plant
and tar plant areas, lagoon sediment, Ice Creek
sediment downstream of the site, and ground
water beneath and surrounding the site. A 1988
ROD addressed the Gold Camp Disposal Area
and documented installation of a cap and slurry
wall, pumping and treatment of  contaminated
ground water, and provisions for supplemental
study and remediation of nonaqueous phase
contaminants found on top of the bedrock.  This
ROD addresses contamination at all areas not
previously addressed,  and  provides  a  final
remedy at the site. The primary contaminants of
concern affecting the soil, sediment, and ground
water  are VOCs  including benzene;  other
organics  including PAHs and phenols;  metals
including arsenic; and other inorganics including
cyanide.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and incinerating onsite approximately
122,000 cubic yards of waste  material from
Lagoon 5, and 31,000 cubic yards of waste coal,
followed by onsite waste fuel recovery (re-use of
the waste heat generated during incineration),
and disposing of the residual ash offsite; in-situ
bioremediation of approximately 475,000 cubic
yards of waste material from Lagoons 1 through
4, the residual soil of Lagoon 5, and the adjacent
inner and outer dikes; excavating  and  onsite
bioremediation   on  a  prepared  pad   of
approximately 40,000 cubic yards of soil from the
Coke and tar plant soil;  pumping and treatment
of ground water at a  future onsite treatment
facility,  with onsite  reinjection  or   offsite
discharge; monitoring ground water onsite and
downgradient of Ice  Creek, and developing a
contingency plan in the event that contaminant
migration is  encountered;  pilot  testing  the
effectiveness  of  in-situ  bioremediation  and
developing a contingency plan for an alternative
remedial  action  for Lagoons 1 through 4, if
necessary;  and   implementing   institutional
controls  including  deed restrictions, and site
access restrictions  such  as fencing.    The
estimated capital cost for this remedial action is
$21,000,000, with an estimated total O&M cost of
$28,500,000. Total estimated cost is $49,500,000.

and operated to achieve a 99.99% destruction of
carcinogenic PAHs. Lagoon 5 materials will be
excavated until EPA  visibly determines that
natural stream sediment has been encountered.
Bioremediation of soil and lagoon sediment must
reduce PAHs to attain a cancer risk level of 10"4
to 10'6 and an HI<1. Chemical-specific levels for
bioremediated  soil include PAHs 0.97 mg/kg
and arsenic 0.56 mg/kg. Chemical-specific goals
for  soil  include PAHs 1.4 mg/kg of organic
carbon and benzene  0.485 mg/kg of organic
carbon.  Leach tests will be performed on  the
treated  waste  materials  to  determine  the
concentrations of arsenic  and cyanide that will
be protective of  the  ground  water.   Ground
water clean-up goals are based  on site-specific
risk assessment, MCLs, and Health Advisories.
Chemical-specific ground  water goals include
benzene 0.005 mg/1, phenol 4 mg/1, total PAHs
0.005 mg/1, and arsenic 0.05 mg/1.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prevent
any future residential  or recreational use of the
site.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The  Anderson Development site is an active
chemical  manufacturing  facility  in  Adrian,
Lenawee County, Michigan.  The site occupies
approximately 12.5  acres  within  a  40-acre
industrial  park,  which  is  surrounded   by
residential areas.  Site features include several
onsite buildings used for manufacturing, storage,
laboratories, and offices, as well  as a 0.5-acre
former process wastewater pretreatment lagoon
containing lagoon sludge and an underlying clay
layer.   From 1970  to  1979, the Anderson
Development  Corporation  (ADC) produced
specialty   chemicals   onsite  including
4,4-methylene bis (2-chlororaniline) (MBOCA), a
hardening   agent  for  the   production   of
polyurethane  plastics.     Untreated  process
wastewater was discharged  directly to surface
water until  1973, when  the State discovered
aniline in a side drain from the facility.  Later in
1973, ADC began separating process wastewater
from  its   cooling   water,  with  subsequent
discharge  of wastewater  to a POTW.  At the
POTW,  MBOCA was settled out with other
solids and applied to the land, which has led to
contamination  at the POTW drying beds.   In
1979, the State ordered the POTW not to accept
the waste  stream  because  of the decreased
efficiency of the POTW resulting from MBOCA
contamination.   In  1979, after MBOCA was
found in onsite  sediment,  production of  the
chemical ceased.   In 1980 and 1981,  the  site
owner and the State cleaned up all contaminated
site areas, except for the onsite lagoon and the
adjacent soil, with MBOCA levels greater than 1
mg/kg by decontaminating the plant, sweeping
streets,   shampooing/vacuuming   residential
carpet, and removing some contaminated surface
soil offsite.  A 1990 ROD addressed site
contamination of surface soil, lagoon sludge, and
underlying lagoon clay. This ROD amends the
1990 ROD, which provided for treatment of the
contaminated media using in-situ vitrification,
and documents the selection of low temperature
thermal desorption  (LTTD)  as  the  preferred
treatment technology, based on cost and other
concerns. The primary contaminants of concern
affecting the soil and lagoon  sludge are VOCs
including  toluene  and   MBOCA  and   its
degradation products; and metals.

SELECTED REMEDIAL ACTION:

The selected amended remedial action for this
site includes excavating and staging 3,000 to
4,000 tons of contaminated soil, clay, and lagoon
sludge with MBOCA concentrations above the
1.6 mg/kg clean-up action level  in an LTTD
device;  performing  treatability  studies  to
evaluate effectiveness of the LTTD technology,
then, if effective, treating the contaminated soil,
clay, and sludge onsite using LTTD; placing the
treated soil, sludge, and clay into the excavated
lagoon, covering the lagoon with clean soil, and
regrading  the  area;  or if the  results  of the
treatability  study   indicate  that  LTTD  is
unacceptable,  using  in-situ vitrification as the
alternate  remediation  technology;  collecting
off-gases and treating the gases using an air
pollution control train, which includes a scrubber
system, air filters, and carbon adsorption beds;
treating aqueous streams from the air pollution
control train using liquid phase activated carbon
beds;  thermally regenerating or disposing  of
spent  carbon and fines from the particulate
removal equipment  offsite;  and  monitoring
ground water and air. The estimated cost of the
LTTD  treatment  options  for  this amended
remedial action is $1,100,000.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 40-acre Berlin and Farro site is a former
liquid incineration and landfill facility in Gaines
Township,  Genesee County, Michigan.  Land
near  the  site  consists   of  woodland  and
agricultural areas.  In addition, the site overlies
two aquifers, which provide well water to the
approximately 80  permanent homes  located
within a 1/2 mile radius of the site.  From 1971
to 1975, Berlin and Farro Liquid Incineration,
Inc., used the site to accept and store industrial
wastes prior to  incineration,  and disposed of
crushed drums  in a 1.1-acre onsite landfill.
During this period, the owners failed to comply
with  air emission  standards,  onsite  storage
volume  limits,  and  permit  standards  that
prohibited onsite disposal of wastes other than
solid  wastes.  The facility also operated two
unauthorized waste storage lagoons and two
unlined storage  lagoons;  illegally  buried five
tanks of wastewater and liquid wastes; operated
underground storage tanks; poured liquid wastes
into subsurface agricultural drains; and dumped
thousands of gallons of barrelled wastes into two
onsite pits.   In 1975, Berlin and Farro's permits
were  revoked; however,  illegal dumping  of
industrial  waste into the lagoons apparently
continued after  the site  was closed.   Several
separate clean-up actions  were  undertaken  by
the PRPs, the State, and EPA during the early to
mid-1980's.  These  activities included, but were
not limited to,  removing lagoon  sludge, the
incinerator  facility, five underground tanks, an
agricultural  drain  and paint sludge  trench,
surface debris, drums, waste piles and soil, and
1,000,000   gallons   of  contaminated  water;
backfilling  the lagoons and old drum landfill;
and  constructing settling ponds.   This ROD
addresses the final remedy for contaminated soil,
sediment, and ground water at the Berlin and
Farro site. The primary contaminants of concern
affecting the soil, sediment, and ground water
are VOCs including
benzene, PCE, TCE, toluene, and xylenes; and
metals including arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating, partially treating using solidification,
and   consolidating  (in   an  onsite  RCRA
containment  cell)  contaminated   soil  and
sediment from the central site area and sediment
from an offsite drain (treatment of the materials
will remove free liquids and render characteristic
waste  and  non-characteristic  RCRA waste);
collection and treating leachate from the cell;
backfilling, covering with soil and revegetating
the  excavated  onsite areas; regrading  the
excavated areas of the drain;  pumping and
treatment of  ground  water from the shallow
portion   of the  aquifer  using  a  system  of
collection trenches, followed by treatment using
air stripping and onsite discharge to the drain;
treating off-gas emissions from the ground water
treatment system; monitoring ground water; and
implementing  institutional controls including
deed restrictions.  The estimated present worth
cost for  this remedial action is $8,119,300, which
includes an annual O&M cost of $233,100 for 30
years.

PERFORMANCE  STANDARDS OR GOALS:

Chemical-specific  soil and sediment clean-up
goals are based on State health-based standards
and  include  benzene 0.02 mg/kg, lead  20.8
mg/kg, toluene 16 mg/kg, and xylenes 6 mg/kg.
Chemical-specific  ground water clean-up goals
are based on health standards, and include
benzene 1 ug/1.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prevent
the installation of drinking  wells  on the site
during remediation.

                                     June 28,1991
 SITE HISTORY/DESCRIPTION:

 The 2-acre Better Brite Plating Chrome & Zinc
 site is composed of two plating facilities in De
 Pere, Brown  County, Wisconsin.    The site
 includes the 1.5-acre Chrome  Shop and the
 0,5-acre   Zinc   Shop,  which   are  located
 approximately 0.5 miles apart. Because of their
 proximity and related backgrounds, the two sites
 were jointly nominated to the National Priority
 List and are addressed as a single site in this
 ROD.  Land use in the area is  predominantly
 residential and commercial, with a  wetlands
 located approximately one-quarter mile from the
 site. The estimated 15,000 area residents use the
 municipal wells drawing from the deep aquifer
 as a drinking water supply.  A municipal well
 located approximately 250  feet from the site is
 thought to influence the ground water flow  in
 the contaminated shallow aquifer, but impacts
 have  not been observed in the municipal well
 onsite. From 1963 to the early 1970% the Zinc
 Shop primarily plated chrome, switching later to
 zinc.  The Zinc Shop has a long history  of
 improper operational procedures and spills into
 the  surrounding soil.   Wastewater  and/or
 plating solutions routinely leaked between the
 floor and sill plate of the building. Reportedly,
 underground vertical plating tanks were used
 early on.   The  Chrome Shop  began chrome
 plating operations during the early 1970's using
 several above-ground tanks and  four buried
 vertical tanks in the plating process. In 1978 and
 1979,  the  Chrome  Shop  was  found  to be
 responsible for surface spills, which resulted  in
 construction  of   a  shallow  ground  water
extraction system around a portion of the site.
 Later, it was determined that the underground
plating tanks from the Chrome Shop had leaked
an unknown amount  of plating solution and
VOCs   into  the  onsite  ground  water.
Consequently, in 1985, the owner of the Chrome
Shop filed for bankruptcy and operations ceased
m 1986.  In 1987,  the State installed ground
water  monitoring  wells at  the  site,  which
identified contamination by metals and VOCs in
soil and ground water. In 1989, the Zinc Shop
closed, and a private contractor removed  the
building  that housed  the Chrome Shop.  The
State constructed a  clay cap and fenced around
the area of highest soil contamination. In 1990,
the Zinc  Shop owner failed to comply with an
AO to conduct clean-up activities. Subsequently,
EPA performed an emergency removal  action,
which  included shipping 350  cubic yards of
hazardous   and   solid  waste  offsite  and
constructing a ground water collection  sump.
Ground water is collected, stored temporarily,
and  treated onsite.   The  residual chromium
sludge from the ground water treatment  is sent
offsite  for recycling.    Later  in  1990, EPA
performed  an additional emergency  response,
and  provided  for  the  construction  of  a
wastewater   pretreatment   system  and   an
extraction system to collect and pretreat shallow
ground water prior to discharge offsite to  the De
Pere wastewater system. This  ROD  addresses
operable unit 1, contaminated ground water and
surface water, as an  interim action.   Future
RODs will  address  remaining soil and ground
water contamination. The primary contaminants
of concern  affecting  the ground water and
surface water are VOCs including 1,1,1-TCA and
1,1-DCA; other organics; and metals  including
chromium, cyanide, and lead.

SELECTED REMEDIAL ACTION:

The selected  remedial action  for this interim
remedy includes continuing and expanding the
current operation of the ground water extraction
system and pretreatment facility, which will
include pretreatment of the additional  water
collected by the surface water and ground water
collection systems,  and the Chrome  and Zinc
shops, with discharge to the De Pere wastewater
system; improving surface water drainage, and
constructing berms to control surface water run-

                                   August 19,1991
SITE HISTORY/DESCRIPTION:

The 658-acre Buckeye Reclamation site contains
a 50-acre former landfill in Richland Township,
Belmont County, Ohio.  Land use in the area is
predominantly agricultural, rural residential, and
strip mining.  A total of 46 domestic wells and
springs are located within 1 mile of the site. The
site  is  situated in  the King's Run drainage
ravine, and is bordered by King's Run to the east
and  Unnamed Run to  the west.  King's Run
flows to the south into  Little McMahon Creek.
The original topography of the valley has been
altered by coal mining and landfill operations.
Prior to 1940, the site served as a disposal area
for coal mine refuse. The county licensed the
area as a public solid waste landfill in 1971, and
the facility accepted general trash, rubbish, and
nonhazardous waste. The landfill also accepted
industrial  sludge and liquids,  most of which
were received between 1976  and  1979, and
deposited  in the  Waste  Pit  located  in  the
northern section of the landfill.  Solid industrial
wastes  also  were  disposed   of along  with
municipal wastes elsewhere in  the landfill. In
1980, the Waste Pit was filled with sludge, mine
spoil, and overburden soil; covered with soil and
garbage; and seeded. Results of the RI indicate
various levels  of contamination in all media
sampled, except air.  This ROD addresses  the
remediation  of  contaminated  leachate  and
ground  water  and  eliminates  exposure to
contaminated  surface  soil.     The  primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, TCE,
and toluene; other organics including PAHs; and
metals including arsenic, chromium, beryllium,
and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
capping the  entire landfill area including the
Waste Pit and suspected sources of recharge for
the Waste Pit and water bearing zones, with a
solid waste landfill cap; installing a leachate seep
and ground  water collection system; treating
collected wastewaters with constructed wetlands
and discharging the treated  waters onsite to
Little  McMahon Creek; conducting  long-term
ground  and  surface water  monitoring;  and
implementing  institutional controls  including
deed, land, and ground water use restrictions, as
well as site access restrictions including fencing.
The  estimated  present  worth  cost  for  this
remedial action is $48,663,000, which includes an
annual O&M cost of $99,000 for 30 years.

PERFORMANCE STANDARDS OR GOALS:

EPA is invoking a waiver of RCRA  closure
requirements due to the steepness of the landfill
slopes, which makes construction of a RCRA
Subtitle  C   cap  technically   impracticable.
Contaminants discharged from the wetlands
treatment  system  will  not  exceed NPDES
discharge limits.  The limits may be modified to
more stringent levels if proven feasible.

INSTITUTIONAL CONTROLS:

Deed, land, and ground water  use restrictions
will be implemented at the site.

                                  September 18,1991
SITE HISTORY/DESCRIPTION:

The 3.5-acre Carter Industrials site is a former
scrap metal storage and salvage  operation in
Detroit, Michigan.   Surrounding land use is
mixed residential  and  light industrial  in  an
urban setting,  Onsite features include several
buildings,  two shelters,  an  incinerator,  a
1,000-gallon underground gasoline storage tank,
and seven piles consisting of approximately
46,000 cubic yards of PCB-contaminated soil and
debris.  From 1966 until  1986, the site was used
as a scrap metal salvage and storage facility,
changing ownership several  times during the
period.   Items accepted for  salvage included
electrical capacitors and transformers.  During
salvage  operations, dielectric fluid  containing
PCBs was spilled from  the capacitors and
transformers  directly onto  the  onsite  soil.
Adjacent commercial, residential, and municipal
properties have been contaminated by direct run-
off  of spilled  material, storm  water  run-off,
wind-blown  dust,  and tracking of  spilled
material by vehicles. In 1986, the State identified
elevated levels of PCBs in onsite soil, which was
later  confirmed   by   EPA  investigations.
Consequently, in 1986,  as  part of a removal
action, EPA  stabilized  the site  by diverting
surface  water  run-off   to  onsite interception
trenches and a treatment  system; excavating and
consolidating onsite contaminated soil and debris
along with offsite residential debris into seven
onsite piles; decontaminating and disposing of
debris offsite; decontaminating alleys and streets
within a 4-square  block area; and fencing the
site.  Also in  1986, the  State removed and
disposed of all PCB-contaminated soil with levels
between  10 to  50  mg/kg from  surrounding
residential  areas offsite.   In 1989,  the PRPs
covered  onsite  piles of  contaminated material
with geotextile and vegetative cover to provide
temporary containment.  This ROD addresses
remediation  of remaining  onsite  and offsite
source material. A subsequent ROD will address
the need for remediation of contaminated sewer
lines  running from the site.   The  primary
contaminants of concern affecting the soil and
debris are organics including PCBs; and metals
including arsenic, cadmium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating approximately 46,000 cubic yards of
onsite and offsite soil contaminated with greater
than 1 mg/kg PCBs; treating onsite and offsite
soil and debris with greater than 10 mg/kg PCBs
onsite  using  low   temperature   thermal
desorption, and solidifying any material that fails
the toxicity  characteristic leaching procedure
(TCLP); disposing  of  all onsite  and  offsite
material contaminated with PCBs 1 mg/kg to
10 mg/kg including all treatment residuals with
less   than  10  mg/kg  PCBs in  an  onsite
containment cell with  a  clay and soil cover;
disposing of any material that cannot meet the
above onsite disposal criteria offsite; installing a
leachate collection and pumpout system in the
containment   cell;  decontaminating   and
demolishing   three  onsite   buildings,   and

PERFORMANCE STANDARDS OR GOALS.

The clean-up goal of 1 mg/kg PCBs in soil and
debris is based on EPA Guidance on Remedial
Actions  for   Superfund  Sites  with  PCB
Contamination.  All soil and debris with greater
than 10 mg/kg PCBs will  be treated onsite. Soil
and  treatment residuals  with 1 to 10 mg/kg
PCBs will be contained  onsite.  Soil clean-up
levels for metal contaminants  are  based  on
teachability testing (or  detection  limits) and
include arsenic 50 ug/kg, cadmium 80 ug/kg,
and lead 100 ug/kg. An  ARAR waiver will be
invoked  for  the  Michigan  Solid  Waste
Management  Rule  that  specifies   isolation
distances for sanitary landfills.

                                  September 30,1991
SITE HISTORY/DESCRIPTION:

The 2-acre Chem-Central site is a bulk chemical
storage facility  in Wyoming,  Kent  County,
Michigan. Land use in the area is a mixture of
residential and commercial. An estimated 10,000
people live within 1 mile of the site and receive
their water supply via the municipal distribution
system.  Two creeks, Cole Drain  and Plaster
Creek, lie in proximity to the site.  Cole Drain,
which  has been included as part  of  the site,
empties into Plaster Creek 2,500 feet north of the
site. In addition, two hotels are located 800 feet
from the site.  Since  1957, Chem-Central has
used the site to receive and hold bulk chemicals
by truck and railroad tanker before redistribution
to  various industries.  Facilities  at  the  site
include a building  with two loading docks and
a  rail  spur  on  the west  side  of the plant.
Approximately 10  above-ground storage tanks
are located along the plant's north side and are
surrounded by a concrete containment wall and
paved ground surface.  Between 1957 and 1962,
hazardous substances  entered the ground as a
result of faulty construction of a T-arm pipe used
to transfer liquid products from bulk  storage
tanks to small  delivery  trucks.   Additional
hazardous substances  may  have entered the
ground through accidental spills.   In  1977,  a
routine  State biological survey of Plaster Creek
identified a contaminated  ditch  containing oils
with organic compounds  including PCBs and
metals, that was discharging into Cole Drain.  In
1977, the State attempted to stop the oil flow by
damming  the  ditch.   In 1978, EPA excavated
sludge from the ditch  and removed the sludge
using  twelve  55-gallon  drums  for   offsite
disposal.  Oils, ground   water, and   various
contaminants continued to enter  the ditch, and
the State unsuccessfully attempted to  filter oil
out of  the water.  Between 1978 and 1986, the
State and EPA focused their efforts on finding
and eliminating  the  source  of  the ditch
contamination through extensive investigations
of area soil, ground water, and surface water.
Results indicated that ground water and  soil
surrounding and north of the Chem-Central
plant were contaminated  with volatile  and
semi-volatile organic compounds.  In 1980, the
State required Chem-Central  to clean up  the
contamination and to institute a ground  water
monitoring program.  Consequently, between
1984 and  1985, three ground water extraction
wells, an  interceptor trench,  and a treatment
system using an air  stripper were  installed.
Contaminated  water,  soil, and sludge  were
removed from the ditch and placed in hazardous
waste landfills, and the ditch was backfilled with
clean soil.  This ROD addresses a remedy for
contaminated onsite soil, contaminated offsite
soil surrounding and north of the plant, and the
ground water contamination plume emanating
from the  plant and  spreading  1,800  feet
northward.   The primary  contaminants  of
concern affecting the soil and ground water are
VOCs including PCE, TCE, and toluene; and
other organics including PAHs and PCBs.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
installing an in-situ vapor extraction system for
onsite soil and two offsite soil areas north  of the
property; using a network of horizontal piping to
collect contaminated vapors in  the soil source
area at the vacuum pump, and treating these
vapors using a vapor phase carbon adsorption
system before discharge  to  the  atmosphere;
continuing the operation and maintenance of the
current ground  water collection and treatment
system; installing, operating, and maintaining an
expansion of the current offsite ground  water
collection system either by extending the current
interceptor trench further east or north,  or by
constructing two additional purge wells east of
the current interceptor  trench; installing  and
operating  a purge well in  the deep lens of
contaminated ground water beneath the main

water using an air stripper with offsite discharge
to a POTVV; collecting oil in the purge wells, and
disposing of the  oil at  an  offsite  facility;
monitoring ground  water; and implementing
institutional controls including deed restrictions.
The  estimated  present  worth  cost  for  this
remedial action is $2,099,000, which includes an
annual O&M cost of  $170,000; or $2,131,000,
which includes an annual O&M cost of $172,900,
depending  on  which  offsite  ground  water
collection option is used.

PERFORMANCE STANDARDS OR  GOALS:

Contaminant goals for soil are based  on  10"
cancer level or  the Human Life Cycle Safe
Concentration (HLSC). Clean-up levels in soil
must  be reduced to less  than 20 times the
ground water standard for each chemical, or soil
leach tests (TCLP) must produce leachate with
contaminant levels  below  the ground water
clean-up levels. Chemical-specific ground water
clean-up goals are based on health-based criteria
including 10"6 risk level or Human Life-Cycle
Safe (concentration)  and State levels  including
TCE  3   ug/1  (health-based),   PCE  0.7  ug/1
(health-based), and toluene 100 ug/1.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prevent
installation of water wells in the site area and to
prohibit development that might disturb onsite
and some offsite soil.

 SITE HISTORY/DESCRIPTION:
The 2,500-acre Conrail Railyard Elkhart site is
composed of a  675-acre railroad facility and
adjacent areas of contamination to the northeast
and northwest  in  Elkhart  County, Indiana.
Major surface water bodies in the vicinity are the
St. Joseph River, located 1 mile north of the site,
and the Baugo Bay located to  the west of the
site, which both have adjacent wetlands and
floodplain areas. From 1956 to the present, the
site  has been  used  as  a  classification  and
distribution  point  for  rail  freight  cars.   Car
repair, engine cleaning,  and diesel refueling
activities were  conducted  onsite.   Reported
onsite  spills  and releases of oil, diesel fuel,
hydrochloric  acid,  caustic soda, and  various
petroleum-related substances from 1976 to 1986
have occurred onsite. EPA investigations during
the mid-1980's detected elevated levels of TCE in
ground water downgradient from the railyard,
and  in the  subsurface soil  at various  points
onsite.  After initially providing bottled water,
in-house carbon filters were provided to  76
residences.    This  ROD  provides  for   the
containment of the contaminated ground water
plume, as an interim action, and provides for a
safe and permanent drinking water supply.  A
subsequent ROD will address contaminated soil
and  ground water,  and will set final  ground
water  remediation  levels.     The  primary
contaminants of  concern  affecting the  ground
water  are VOCs including  TCE and carbon
tetrachloride.

SELECTED REMEDIAL ACTION:

                                     June 28,1991
 SITE HISTORY/DESCRIPTION:

 The 80-acre Dakhue Sanitary Landfill site is an
 inactive sanitary waste municipal landfill located
 in  Hampton  Township,   Dakota  County,
 Minnesota. Land use in the area is agricultural
 and residential. The landfill overlies a sand and
 gravel  surficial aquifer that is not  a drinking
 water source and that extends downgradient of
 the site.  However, 15 residential wells are
 located within 1 mile of the site, and a municipal
 water supply well is located over 3 miles south
 of the  site, all of which extract ground water
 from  a  deeper  aquifer.    Investigations are
 ongoing to determine whether the two aquifers
 are hydraulically connected. From 1971 to 1988,
 Dakhue  Sanitary Landfill, Inc.,  owned  and
 operated  the  landfill, and  accepted  mixed
 municipal and  commercial wastes  and small
 amounts of industrial waste.  State investigations
 conducted between 1983 and 1989 identified a
 variety of contaminants onsite.  Investigations
 during the RI/FS identified VOCs, organics, and
 inorganics in the surficial onsite aquifer, and it
 has been determined that the possible source of
 contamination  is  related  to the  municipal,
 industrial, and commercial waste disposed onsite
 in the  landfill.   Ongoing  investigations are
 required to further define onsite ground water
contamination.  As  a result,  the site will be
 remediated as two operable units (OUs).  This
ROD addresses the source of the contamination
as OU1.  A  future ROD will address ground
water contamination and possible remediation of
the downgradient plume, as OU2.  The primary
contaminants of concern affecting the soil  and
debris  are organics  including phenols;  and
metals including arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
capping the  site  with a  final  cover system
consisting of  a  gas  control  layer, a barrier of
low-permeability material, and a drainage layer;
revegetating the area; treating air emissions from
gas vents; conducting air  and ground water
monitoring; and installing a fence around the site
perimeter.  The capital cost for this remedial
action is $9,800,000, with an estimated annual
O&M cost of $54,000 for 2 years.

                                     June 7,1991
 SITE HISTORY/DESCRIPTION:

 The  Enviro-Chem  site is a  former  waste
 recovery/reclamation/brokerage  facility   in
 Boone County, Indiana.  Adjacent to the site is
 another Superfund site, the Northside Sanitary
 Landfill  (NSL)  which, prior  to this ROD
 amendment, was to be remediated in a combined
 remedy for both sites.  Land use in the area is
 agricultural to the south and east, and residential
 to the north and west, with approximately 50
 residences located within one mile of the sites.
 Run-off from the  sites  is collected in a ditch,
 which flows offsite and eventually empties into
 a reservoir that provides approximately 6 percent
 of  the  drinking  water  for  the  City  of
 Indianapolis. Enviro-Chem began operations in
 1977   as  a  recovery/reclamation/brokerage
 facility, accepting solvents, oils, and other wastes
 from   industrial  clients.    Accumulation  of
 contaminated   stormwater  onsite,  poor
 management of the drum inventory, and several
 spills led to State and EPA investigations of the
 site. Between 1977 and 1981, the State permitted
 Enviro-Chem to dispose of  part of its waste at
 the adjacent NSL. In 1981, a consent decree was
 issued against Enviro-Chem giving them until
 November 1982 to comply with environmental
 laws and regulations.  In May 1982,  the State
 ordered  Enviro-Chem   to  close  and
 environmentally secure the site because it failed
 to  reduce  hazardous  waste  inventories.
 Subsequently, two emergency removal actions
 were conducted to remove the major sources of
contamination.      From   1983  to   1984,
approximately 30,000 drums, 220,000 gallons of
waste, and 5,650 cubic yards of soil and sludge
were removed offsite  and  treated.   In 1985,
20,000  gallons of  contaminated  water were
removed. A 1987 ROD provided a combined
 remedy for both NSL and Enviro-Chem due to
 their proximity and other similarities.  The 1987
 ROD  addressed source  control through soil
 excavating, dewatering,  and onsite  disposal,
 followed  by  capping;  pumping  and onsite
 treatment of ground water; and implementing
 deed and access restrictions. However, since the
 signing of the ROD,  EPA and  the State have
 been engaged in negotiating with the PRPs for
 each site.  These negotiations have resulted  in
 separate,   complementary   remedies   and
 individual consent  decrees for  each site, and
 modifications  to the original selected remedy.
 This ROD amends the 1987 ROD and provides a
 comprehensive site remedy for the Enviro-Chem
 site addressing source control instead of ground
 water remediation. The primary contaminants of
 concern affecting the  soil are VOCs including
 PCE, TCE, toluene; and other organics including
 phenols.

 SELECTED REMEDIAL ACTION:

 The  amended remedial  action  for this site
 includes treating contaminated soil onsite using
 soil vapor extraction with a granulated activated
 carbon system to control the extracted vapor, if
 necessary; and   implementing   a  contingent
 remedy for a subsurface ground water collection
 and  treatment  system based  on  monitoring
 results, if clean-up objectives are not reached in
5 years. Other remedial actions documented in
 the 1987  ROD including  capping the  site,
implementing  site  access  restrictions,  and
monitoring of the subsurface and surface water
are not affected by  this amendment.   The
estimated present worth for this remedial action
ranges  between $5,000,000 and $9,000,000. No
O&M  costs were provided  for  this remedial
action.

                                     June 10,1991
SITE HISTORY/DESCRIPTION:

The 20-acre Fadrowski Drum Disposal site is an
inactive industrial  landfill within the  city of
Franklin,   Milwaukee  County,   Wisconsin.
Surrounding land use is mixed residential and
commercial. The western portion of the site lies
within the floodplain of the Root River,  and
approximately 9 acres of wetlands are  located
onsite. From 1970 until 1982 when the property
was  sold,  the  site  was  an unregulated  and
unlicensed landfill allowed only to receive clean
earth  fill   containing  construction  debris.
However,  hazardous waste, including  several
hundred drums of  unknown  material  and
lubricant sludge, were illegally buried onsite.
State investigations in 1981 identified evidence of
improper  disposal  of solid wastes including
crushed drums, and boiler and foundry wastes.
In 1982, the site was purchased by Menard, Inc.,
with plans to use the property as a source of fill
material. In 1983, excavation began onsite and
during this work various containers of waste and
sludge  were uncovered, some  drums  were
inadvertently crushed, and liquids and sludge
were released into onsite soil. The State directed
the site owners to  contain the exposed waste
until it could be sampled and characterized, but
instead  the owners  constructed  berms,  then
covered the waste material with day, without
approval.  The RI/FS was conducted by a PRP,
Acme Printing Ink Company.   The RI  located
several buried drums and identified locations
likely  to  contain  additional  buried  drums.
Miscellaneous   low-level  soil  and  sediment
contamination  was also delineated.  Ground
water in the thick, continuous layer  of  clay
below the site was found to contain low levels of
cyanide, mercury, chromium, and barium.  EPA
sampling has  shown that  nearby residential
Water supplies have not been impacted by the
contamination.   This  ROD   addresses  soil
contamination to prevent or reduce the migration
°f contaminants into the ground water.  The
primary contaminants of concern affecting the
soil, sediment, and debris are VOCs including
toluene and xylenes; other organics including
PAHs and pesticides including DDT; and metals
including arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
excavating previously identified drums and 25
cubic yards of hazardous soil, and recycling, or
treating and disposing of the drummed waste
offsite; constructing  trenches to  locate and
excavate additional containerized waste and the
surrounding characteristically hazardous soil;
treating any contaminated soil onsite, followed
by offsite disposal of the residuals; constructing
a landfill cap and a  leachate collection system,
and disposing of any leachate exceeding State
levels offsite at a POTW or RCRA treatment
facility;   allowing  natural   attenuation  to
remediate ground water; monitoring ground
water and surface water for 30 years to ensure
effectiveness  of  the cap;  and  implementing
institutional controls to  limit  land and ground
water use, and site  access restrictions such as
fencing.  If  ground water conditions worsen or
do not improve over a reasonable period of time,
EPA may evaluate  the options  for  a ground
water treatment program. The estimated present
worth cost for this remedial action is $2,230,000,
which includes an annual O&M cost of $32,100
for 30 years.

PERFORMANCE STANDARDS OR GOALS;

Through  removal of buried  drums  and the
containment  of   remaining   low-level
contamination, it  is anticipated  that ground
water will  meet  clean-up standards through
natural attenuation.   Ground water clean-up
standards are based on Wisconsin Preventive
Action Limits (PALs), which are more stringent
than Federal standards.

SITE HISTORY/DESCRIPTION:

The 8-acre Folkertsma Refuse site is an inactive
industrial  landfill  in Walker,  Kent  County,
Michigan.   Surrounding land use is primarily
industrial with a few private residences in the
vicinity.   The  site is  partially bordered by
woodlands, and migration of contaminants has
impacted a 100-year floodplain and the scattered
wetland areas of Indian Mill Creek located to the
south.   The site overlies  surficial glacial and
bedrock aquifers,  both  of which are used for
local drinking water supplies.  Onsite features
include an uncapped landfill, a man-made creek,
and a drainage ditch that join and discharge to
Indian Mill Creek; an office building; and three
warehouses. Prior to 1965, the site was used as
a muck  farm. From 1965 until 1972, industrial
wastes  including  foundry   sand,   chemical
products,   construction   debris,  and  other
industrial wastes were disposed of in the onsite
landfill.  The primary fill material in the landfill
is foundry sand. Since 1972, the site has been
operated as a pallet repair and  manufacturing
facility.    In  1984, EPA  identified  elevated
contaminant levels in the onsite drainage ditch
sediment,  but not  in  onsite  ground water.
Further  investigations  in  1985  and   1988
characterized  onsite  and  offsite (Indian  Mill
Creek)  contamination,   and   determined  the
potential for future ground water contamination.
This  ROD addresses engineering controls for
source material and management of migration of
contaminated ground water, as a final  remedy.
The primary contaminants of concern affecting
the landfilled material, sediment, and ground
Water are VOCs; other organics including SVOCs
and  PCBs;  and   metals including  arsenic,
chromium, and nickel.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and dewatering approximately 1,300
cubic yards of contaminated sediment from the
man-made creek, the drainage ditch, and Indian
Mill  Creek, and consolidating these within the
landfill area; capping the landfill area with a clay
cap and revegetated soil cover installing passive
landfill gas vents, if necessary; converting the
man-made  creek  and  the  drainage  ditch  to
permeable subsurface drains to  provide  for
landfill  surface drainage; monitoring ground
water and  surface  water; and  implementing
institutional controls such as deed and ground
water use restrictions,  as well  as site access
restrictions  such as fencing.  The  estimated
present  worth cost for  this  remedial  action is
$1,500,000, which includes an annual O&M cost
of $58,000 for the  first year. O&M  costs for
subsequent years were not provided.

PERFORMANCE STANDARDS OR GOALS:

The remedial action is designed to reduce the
excess lifetime cancer risk to the 10"4 to 10'6
level and the noncarcinogenic HI Ł 1.
Chemical-specific  clean-up   goals  were   not
provided.

INSTITUTIONAL CONTROLS:

Deed and ground water use restrictions will be
implemented  at the site to prevent  future
disturbances of the cap  and landfill materials,
and future installation of drinking water wells.

                                  September 30,1991
SITE HISTORY/DESCRIPTION;

The 30-acre Fultz Landfill site is a privately
owned  inactive  sanitary landfill on the north
slope of a ridge that overlies abandoned  coal
mines in Jackson Township, Guernsey County,
Ohio.   Land use in  the vicinity of the site is
primarily rural to the south, north, and east; and
residential and light industrial to the west.  The
site lies  within the drainage basin of Wills Creek,
which flows north adjacent to  the site and is
used by the City of Cambridge as the municipal
water supply.  The northern half of the landfill
lies in an unreclaimed strip mine where surface
mine  spoil  and  natural soil form  a  shallow
aquifer.   The southern half of the landfill lies
25 to  80  feet above an  abandoned  flooded
underground mine in the same coal seam as the
strip mine.   The flooded  underground mine
forms an aquifer, which also  is utilized  for
drinking water.   Six  ponds,  designated as
wetlands, are located on the north side of the
landfill  in the area of unreclaimed strip mine
spoil. Surface water  run-off and leachate from
the landfill  collect in several of  these ponds.
From 1958 to 1968, the landfill was operated as
an open dump.  In 1969,  the site was licensed by
the County and began to accept household,
commercial, and industrial solid waste.  During
the 197(ys, the  landfill operator was cited  for
various  violations including inadequate daily
cover of waste,  receiving  unauthorized  waste,
leachate  run-off, blowing debris, and open
dumping; and in 1985, onsite landfill operations
ceased.  Disposal records show that an estimated
6.240  drums   containing  chlorinated   and
non-chlorinated solvents and plating sludge were
disposed of in the landfill.  Records also show
that drummed  liquid and semi-liquid wastes
were  disposed   of onsite,  and  some  of  the
solvents were poured directly onto the ground
frtd burned.   Investigations in 1988 by EPA
indicated  that  ground   water  and   leachate
contaminants emanating from  the  site have
contaminated the shallow aquifer and, to a lesser
extent,  the  deep  mine aquifer.   This  ROD
addresses all contaminated media, and provides
a  final remedy for the  site.   The  primary
contaminants  of  concern  affecting  the  soil,
sediment, debris, ground water, and  surface
water are VOCs including benzene, PCE,  TCE,
toluene, and xylenes; other organics including
PAHs  and phenols; metals  including arsenic,
chromium, and lead; and other inorganics.

SELECTED REMEDIAL ACTION:

The selected  remedial action for this site includes
constructing a containment berm and  capping
the  entire  30  acres of the  landfill  with  a
multi-layer cap; installing structural supports for
voids in the underground  mine to prevent cap
damage by  subsidence;  constructing an onsite
treatment plant and leachate collection system;
pumping and onsite treatment of contaminated
ground water and leachate using oxidation and
precipitation to remove metals, and filtration and
carbon adsorption to remove organics, or using
another treatment based on the outcome of a
bench-scale  treatability  study; discharging the
treated   effluent  onsite  to  surface  water;
regenerating spent carbon or disposing of the
carbon offsite; disposing of sludge resulting from
the treatment plant processes offsite; constructing
surface water and  sediment controls to divert
run-off  away  from the  landfill;  mitigating
affected wetlands; providing an alternate water
supply for contaminated  residential  wells by
connecting these homes to a municipal water
supply; monitoring soil, sediment, ground water,
and air; and  implementing institutional controls
including deed restrictions to limit ground water
and  land use,  and  site  access  restrictions
including fencing. The estimated present worth
cost for this remedial action is $19,480,700, which
includes an  annual  O&M  cost of $218,000 for
30 years.

                                  December 21,1990
SITE HISTORY/DESCRIPTION:

The  70-acre G&H Landfill site is an inactive
landfill in Shelby Township, Macomb County,
Michigan.      Surrounding   land   use   is
predominantly  residential with adjacent light
industrial facilities and a recreational area that
includes  wetland  and woodland habitats.  The
site  overlies  two ground water  aquifers, the
uppermost  of which is the source of drinking
water for  some  eastern area residences  and
industries.  A portion of the site is located within
the 100-year floodplain of the Clinton River. The
site  is  subdivided into  three  landfill  areas: a
44-acre Phase I  landfill area, a 17-acre Phase II
area, and an 8-acre Phase III landfill area. From
1955 to 1973, G&H landfill  accepted municipal
refuse, and solid  and liquid  industrial wastes
including  solvents,   paints,   varnishes,  and
lacquers.  In addition, from 1955 to 1967, waste
oil and water mixtures were disposed of at the
landfill.  Several unsuccessful attempts were
made by  the landfill operators to reclaim the oil,
by pumping  the oil into settling ponds. After
the  oil   was allowed to settle,  the  volatile
components evaporated, and the resulting sludge
was  periodically  removed  and buried  in the
landfill. In 1965 and  1966, the State determined
that  improper liquid  waste  disposal operations
and  waste oil disposal/reclamation activities  at
the landfill  were contributing to onsite  ground
water contamination  and oil seeps south of the
site.   Based  on  these  findings,  all  disposal
operations  were ordered to cease.   The landfill
continued to  operate as a sanitary landfill until
1973, at  which  time it  was closed without a
proper closure  plan.   From 1982  to 1989, EPA
initiated  four removal actions at the  site  to
restrict public access to contaminated  ground
water  and  oil  seeps,  and   to  prevent  the
migration of PCB-contaminated oil.  In 1989,
approximately  2,400  gallons  of  a   PCB-
contaminated oil  and  water mixture  were
removed  and disposed of at an offsite thermal
destruction  facility.   The site has  been divided
into two operable units (OUs) for remediation.
This ROD addresses contaminated soil, sediment,
and   landfill   material   (OU1);   and   the
contaminated  ground  water plume,  landfill
leachate, and oil seep (OU2).  The ground water
contaminant   plume  and  the  solvent/oil-
contaminated  soil  and landfill  debris in the
Phase I landfill area have been identified as the
principal threat.  The primary contaminants of
concern affecting the soil, sediment, debris, and
ground water are VOCs including benzene, TCE,
toluene, and xylenes; other organics including
PCBs; metals including arsenic, chromium, and
lead; and oils.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
constructing a landfill cover over the site to meet
current  State  landfill  closure   requirements;
constructing a subsurface barrier wall around the
perimeter of the landfill  areas  and oil seeps;
instituting  leachate  collection and  treatment;
excavating soil and sediment outside the slurry
wall with PCB concentrations greater than or
equal to 1 mg/kg,  followed  by consolidating
these under the landfill cover if less than 500
mg/kg, or treating the  soil and  waste using
offsite incineration, vitrification, or some other
technology approved by EPA for the destruction
of PCBs if concentrations  are greater than or
equal to 500 mg/kg; replacing affected wetlands;
pumping and treating the contaminated ground
water plume outside the slurry wall, followed by
onsite discharge to the adjacent Clinton River or
to a treatment  plant if pretreatment criteria are
met; connecting  nearby residents to the  local
municipal water  supply;  monitoring  ground
water, surface water, and air; and implementing
deed and ground water use restrictions, and site
access   restrictions  such  as fencing.   The
estimated present worth cost for this  remedial
action   is  $40,000,000,  which  includes  an
estimated annual O&M cost of $750,000 for 30
years.

PERFORMANCE STANDARDS OR GOALS:

Excavated soil and sediment will be treated to
1 mg/kg to destroy PCBs if PCB concentrations
are greater than or equal to 500 mg/kg, or will
be  consolidated   in   the   landfill  if  PCB
concentrations are less than 500 mg/kg. Ground
water clean-up standards are based on  State
standards and SDWA MCLs.  Chemical-specific
goals  include vinyl chloride  0.02 ug/1 (State),
benzene 1 ug/1  (State),  PCE 0.7 ug/1  (State),
TCE3ug/l  (State), xylenes  20 ug/1  (State),
arsenic 0.02 ug/1 (State) (may change; arsenic
standard  will   be  established   based  on
background), and lead 5 ug/1 (State).  NOTE:
An ESD is adjusting  several ground  water
standards.  Existing standards less than 1 ug/1
will be adjusted to 1 ug/1 for carcinogens, which
is the  approximate detection limit for chemicals
of concern.   Standards less than  1 ug/1 for
inorganics will be adjusted to background levels
to be determined by EPA.

INSTITUTIONAL CONTROLS:

Deed  and ground water use restrictions will be
implemented to supplement engineering controls
as appropriate until clean-up standards are met.

                                    March 29,1991
SITE HISTORY/DESCRIPTION:

The 72-acre Kentwood Landfill site is an inactive
municipal landfill in Kentwood, Kent County,
Michigan.  Land use in the area  is primarily
residential  and  recreational.    Twenty-two
residences to the south and east of the site use
ground  water  as their drinking water supply.
Landfilling operations at the site began in the
1950's, and continued intermittently until the
county capped and closed  the landfill in 1976.
The  site consists of two  municipally owned
landfill  areas:  a larger original landfill; and a
20-acre  southern  extension  located  south-
southeast of the original landfill. Both landfills
are constructed  into  the  uppermost aquifer
beneath the site, and as a result, the landfilled
wastes including garbage, rubbish, construction,
and demolitions wastes are in direct contact with
the upper aquifer ground water.  Site disposal
records   show  no  indication  that  RCRA
hazardous wastes were placed into  the landfills.
In 1983, construction of a leachate collection
system  to  pump leachate to a  POTW  was
completed on  the eastern  side of  the original
landfill;  however, contamination from leachate is
still of concern.  The primary contaminants of
concern  affecting the debris, ground water, and
leachate are VOCs including benzene, PCE, and
TCE;  other organics; and  metals  including
arsenic,  chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
improving the landfill cap to include gas controls
and a leachate collection system; pumping and
pretreating ground water onsite along with
collected leachate, as needed, before discharging
to a POTW; monitoring sediment, ground water,
surface  water,  and air;  and  implementing
institutional controls including deed and ground
water use restrictions, and site access restrictions
such as fencing. If for any reason the leachate or
contaminated ground water cannot be treated by
the POTW, these liquids will be treated onsite,
with  subsequent onsite discharge  to  surface
water. The estimated present worth cost for this
remedial action is $5,700,000, which includes an
annual O&M cost of $210,000 for years 0-9, and
$200,000 for years 10-30.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific clean-up  goals  for  ground
water in the aquifer are based on SDWA MCLs
and State  standards including benzene 1 ug/1
(State), PCE 0.7 ug/1 (State), TCE 3 ug/1 (State),
arsenic 0.02 ug/1 (State),  chromium 30 ug/1
(State), and lead 5 ug/1 (State).

INSTITUTIONAL CONTROLS;

Deed restrictions will be implemented to prevent
cap  erosion  and  human  exposure  to  site
contaminants,  and  to  provide site  security.
Ground    water  use   restrictions  will   be
implemented in areas with contaminated ground
water.

                                 September 23,1991
SITE HISTORY/DESCRIPTION:

The 45-acre Lemberger  Landfill  (LL) site is a
former  land disposal facility  in  Manitowoc
County, Wisconsin.  The site is located within
one-quarter mile of another Superfund site, the
45-acre Lemberger Transport & Recycling (LTR)
site.  Land use in the  area is predominantly
agricultural, with four residences within 1,000
feet of the sites. Ground water,  as well as the
Branch River located  less than 1 mile west of
both sites, is used as a source of drinking water.
From 1940 to 1969, Franklin Township used 21
acres of the LL site as an open  dump.  After
1970, the  State  licensed  the  landfill to receive
only municipal  waste and power plant fly ash
and bottom ash.  In  1976,  the LL site ceased
operations except for disposal of fly ash to bring
the site to final  grade. All industrial waste was
diverted to the  nearby LTR site.  From 1970 to
1976, LTR received industrial waste and a variety
of  liquids, sludge, and slurries, which were
deposited onsite in unlined trenches.  As a result
of reports of contaminated material seeping onto
local properties, a number of State investigations
were  conducted that identified  VOCs  levels
above  State  standards  in  residential  wells.
Affected residences received deeper replacement
wells that have not shown contamination.
Because  of the proximity  of  the  sites and
similarity in the types of wastes, the the LL and
LTR sites will be remediated concurrently.  This
ROD  provides  a final remedy  for  source
contamination at the  LL  site and  ground  water
contamination at both the LL and LTR sites, as
the first operable unit (OU1).  A future ROD will
address the landfill contents at the LTR site, as
OU2.   The primary  contaminants of concern
affecting the soil, sediment, debris, and ground
water are VOCs including PCE,  TCE, toluene,

SITE HISTORY/DESCRIPTION:

The 45-acre Lemberger Transport and Recycling
(LTR) site is a former land disposal facility in
Manitowoc County,  Wisconsin.   The site  is
located within one-quarter mile of the 45-acre
Lemberger Landfill (LL) site.  Land use in the
area is predominantly agricultural,  with four
residences within 1,000 feet of the site. Ground
water, as well as the Branch River located less
than 1 mile west of both sites,  is used as a
source of drinking water. From 1970 to 1976, the
LTR site received industrial waste and a variety
of liquids, sludge, and slurries,  which  were
deposited  in  unlined trenches.  From 1940 to
1969, Franklin Township used 21 acres of the LL
site as an open dump.  After 1970,  the State
licensed the landfill to receive  only municipal
waste and power plant fly ash and bottom ash.
All industrial waste was diverted to the nearby
LTR site.   Reports of contaminated material
seeping onto local properties prompted  State
investigations that revealed VOCs in residential
wells  in excess of State standards.  Affected
residences received  deeper replacement  wells
that have not shown contamination. Because of
the similarity of contamination and proximity of
the sites, the LTR and LL sites will be addressed
concurrently. This ROD provides a final remedy
for ground water contamination at both the LTR
and LL sites, as the first operable unit (OU1).  A
future ROD will address the landfill contents at
the LTR site, as OU2. The primary contaminants
of concern affecting the ground water are VOCs
including PCE, TCE, toluene, and xylenes; other
organics including PCBs and  pesticides; and
metals including arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
building an  onsite treatment facility at the LL
site and treating contaminated ground water
from   both   sites  using   electrochemical
precipitation to remove inorganic contaminants
and granular activated carbon to remove organic
contaminants, unless treatability studies deem
another  technology  to  be  more  effective;
blending water extracted from the slurry wall to
be constructed at the LL site with ground water
extracted for remediation, and treating it onsite
at the treatment facility;  temporarily  storing
residual  sludge  onsite,   then  treating  and
disposing of the residual sludge as part of the
future LTR source control remedy or  treating
and disposing the sludge offsite  at a RCRA
landfill   according  to   Federal  and  State
regulations; recycling spent carboy if possible;
discharging the treated effluent into the Branch
River; providing an alternate water supply to
residents whose water supply is disrupted due
to the  operation  of  the extraction  system;
investigating   and  mitigating  any  affected
wetlands;  monitoring  ground water;  possibly
implementing  institutional controls  including
deed  and ground  water  use restrictions; and
constructing  a  security   fence  around   the
treatment facility to limit general accessibility to
the facility and the potential for public exposure.
The  estimated  present  worth  cost  for  this
remedial action is $19,200,000, which includes
the source control remedy for the LL site and an
annual OfaM cost of $731,000 for years 0-1 and
$596,000 for years 2-30.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The MacGillis & Gibbs/Bell Lumber & Pole site
consists of two active, adjacent wood preserving
facilities, referred  to  as the M&G and  Bell
facilities, in New  Brighton, Ramsey County,
Minnesota. Land use in the area is residential
and  commercial.   Several lakes,  streams, and
wetlands are located within 2 miles of the site.
Most local residents receive drinking water from
10 municipal  wells,  the nearest of which  is
located one-quarter mile southeast of the site.
There are also a limited number  of residential
wells existing in the area. This ROD addresses
the 24-acre M&G facility on the eastern portion
of the site.  Site features include a disposal area
in the west-central portion of the facility used to
dispose of PCP-contaminated wood chips, settled
solids, spent  treatment solutions, and copper
chromium  arsenic  (CCA) contaminated drum
shells; onsite drums; and a storage area. From
the late 1920's to 1970, M&G used the site  to
treat wood poles  with  various  preservatives
including creosote and PCP. Process wastewater
from these activities may have been discharged
to the disposal pond. In 1970, M&G began using
only  CCA for treatment and began recycling the
process solution within  the  treatment system.
Investigations conducted by EPA have detected
contamination  of  the  onsite   surface  and
subsurface  soil and  ground  water, which  is
thought to be a result of leaking pipes, drippings
from  treated   poles,  contamination  from the
disposal area, and an onsite spill of 4,000 to 5,000
gallons  of CCA  in   1979.   In 1988, M&G
conducted  initial  clean-up  activities   by
overpacking and storing onsite approximately
200  deteriorated  drums   containing   PCP-
contaminated  soil and waste. In 1989, a thick
layer of PCP-contaminated oil, referred to as the
LNAPL plume, was identified floating on the
upper  aquifer.   Subsequently,  a pump  was
installed in an onsite well to recover the oil,
which is currently stored onsite  in the drum
storage facility. In 1988, EPA initiated pilot tests
for soil washing to remove PCP and PAHs from
contaminated onsite soil, and  in 1989 initiated
tests for a  mobile biological ground water
treatment system.  EPA has divided the site into
two operable units (OUs) for remediation. OU1
will  address remediation within the  onsite
disposal area of  the M&G facility.  OU2 will
address ground water remediation for the entire
site, as well as remediation of  soil, process and
storage tanks, and waste containers outside of
the disposal area. This ROD provides an interim
remedy for OU2.  The primary contaminants of
concern affecting the soil, debris, sludge, and
ground  water are organics  including dioxins,
PAHs, and PCP; and metals including arsenic
and chromium.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
removing 100,000 gallons of PCP waste oil and
sludge  from abandoned,  above-ground  and
underground  PCP  process/storage   tanks;
decontaminating, dismantling,  and disposing of
offsite   the   waste  process/storage   tanks;
separating PCP  wastes  and  decontamination
liquids into oil  and water phases using an
oil/water separator; plugging  a discharge line
from one of the underground  vaults to the
disposal offsite  area; pumping ground water
from beneath the LNAPL plume to  enhance
LNAPL  recovery  via  a   ground   water
depression/oil extraction process; containing and
onsite storage of PCP-contaminated  oil  and
sludge  from tanks,  residuals  from  ground
water/wastewater treatment facility, and LNAPL
oil from ground water; treating ground water,
and tank and tank decontamination wastewaters
using an onsite  bioremediation  wastewater
treatment  facility  and, if necessary,  a carbon
adsorption polishing unit; discharging effluent

                                     March  29,1991
SITE HISTORY/DESCRIPTION:

The 48-acre Main Street WeH Field (MSWF) site
is in Elkhart, Elkhart County, Indiana. The well
field provides the primary water supply for the
44,000  city residents.  Adjacent to  the site are
several industrial properties, Excel and Durakool
to the  east; Elkhart Products to the  west that
used TCE and other organic solvents  as part of
their  operations.   The  site is bounded by
Christiana Creek to the north and the  St. Joseph
River to the south.  MSWF is located in both a
wetlands and a floodplain, and overlies a sole
source aquifer.  Since the early 1900's, an onsite
treatment and pumping station has been used
for the purification and distribution of water to
the surrounding community.   The well  field
contains 17 production wells, two interceptors
used as production  wells, two 2-million gallon
storage  tanks,  an  air  stripper facility,  and
recharge  ponds.   Site  contamination  first
occurred during the 1950's when phenols from a
nearby fuel tank farm, east of  the well field,
were   detected   in  onsite    wells.     The
contamination was mitigated by excavating six
recharge ponds and diverting the water to those
ponds from Christiana Creek.  During routine
sampling   in   1981,  EPA  identified   TCE
contamination in onsite wells.  Sampling wells
were  installed  on  the  Excel  and  Durakool
properties, and the  results  of  this  testing
indicated these industries were the likely sources
of contamination.  Subsequently in 1981, the city
constructed two eastern interceptor wells, which
discharged to Christiana Creek, and removed the
nearby production wells from  service.  As  a
result, TCE levels in finishing and production
wells dropped significantly. In 1984, TCE levels
on the west side of the field increased, and EPA
suspected a second plume had impacted the well
field. A 1985  ROD provided for construction of
an air stripping facility to treat water from the
seven production wells  and the two eastsidc
interceptions.  Subsequent investigations further
characterized onsite contamination and led to the
discovery of a TCE-contaminated paint layer on
the soil in eastern area of the site.  This ROD
addresses management  of migration  of  the
western contaminant plume, as  well as source
control on the east side of the well field. A third
remedial action  may be necessary if  further
onsite contamination is identified.  The primary
contaminants of  concern affecting the  soil and
ground  water  are VOCs including PCE, TCE,
and xylenes; other organics including PAHs; and
metals including arsenic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating 22,000 cubic feet of contaminated soil by
in-situ vacuum extraction; removing 60 cubic
yards of soil containing the paint layer, followed
by  offsite  incineration  or  suitable treatment
based  on waste characterization  and offsite
disposal in accordance with the  Land Disposal
Restrictions  Soil   and   Debris   Treatability
Variance; constructing new interceptor wells  on
the west side of the field; continued pumping
and treatment of ground water using the existing
air stripping unit; monitoring ground water; and
implementing  institutional  controls including
deed restrictions.  The estimated present worth
cost for  this remedial action is $3,370,000, which
includes an estimated annual  O&M  cost  of
$130,000 for 20 years.

PERFORMANCE STANDARDS OR GOALS:

Performance standards for soil and ground water
are based on a 10"5 excess lifetime cancer risk.
Chemical-specific goals  for soil include  TCE
100 ug/kg.    Interceptor  wells  will   remain
operational as long as plumes entering  the field
have  cancer risk  levels  greater than  10".
Chemical-specific goals for ground water include
PCE 0.6 ug/1 and TCE 1  ug/1.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:
The 68-acre Michigan Disposal Service Landfill
site  is  an   inactive   municipal  landfill  in
Kalamazoo, Kalamazoo County, Michigan. Land
use  in the area is predominantly  industrial,
commercial, and residential. The eastern border
of the site lies within a wetland and the 100-year
floodplain of nearby Davis Creek. From 1925 to
1961, the site  was owned and operated by
private   parties  as  a   municipal   landfill.
Forty-seven acres of the total site were used as a
landfill.   In  1961, the  City of Kalamazoo
purchased the  property and  began accepting
wastes from  residences, businesses,  and  local
industries.  The majority of these wastes were
incinerated onsite,  with onsite disposal of the
ash.  From 1968 to 1981, the site was licensed to
accept only inert wastes, and incineration ceased
due to new air pollution regulations.  In 1981,
the  site  was  sold, and  subsequently,  was
operated  as  a licensed landfill.   During the
mid-1980's, the State conducted investigations as
part of a landfill extension request These onsite
studies documented that wastes leaching  from
the  landfill   had  contaminated  onsite  soil,
sediment, and  ground water.   To  continue
landfill operations, the owners were ordered to
install a collection system to intercept  leachate
prior to  entry into Davis Creek to  prevent
contamination of the creek. This ROD addresses
onsite  contaminated soil,  sediment,  ground
water, and surface water, as a final remedy. The
primary contaminants  of concern affecting the
soil, sediment, debris, ground water, and surface
water  are VOCs  including   benzene;  other
organics including PCBs; and  metals including
arsenic, chromium, and lead.
SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
installing a clay cap and revegetating the landfill
contents;  installing a leachate  collection system
and  a gas  venting  system  for the  landfill;
pumping and pretreating ground water onsite, as
required, followed by offsite discharge of the
ground water/leachate to a POTW; monitoring
all  media;  and   implementing  institutional
controls, and site access restrictions including
fencing. The estimated present  worth cost for
this remedial action is $8,269,500, which includes
an annual O&M of $253,800 for 20 years.
PERFORMANCE STANDARDS OR GOALS:
Ground water  clean-up  goals  are  based on
SDWA and State standards.  Chemical-specific
goals for ground water include benzene 1 ug/l
(State), arsenic 0.02 ug/l (State), and lead 5 ug/l
(State).
INSTITUTIONAL CONTROLS:
Deed and ground water use restrictions will be
implemented  to  prevent  exposure  to   site
contaminants.

SITE HISTORY/DESCRIPTION:

The 24-acre Motor Wheel site is  an inactive
industrial waste disposal site in Lansing, Ingham
County,  Michigan.   Land use  in  the area is
predominantly industrial.   The site overlies a
glacial till and a glacial aquifer.  From 1938 to
1978, the Motor Wheel Corporation used the site
for the disposal of solid and liquid industrial
wastes including paints, solvents, liquid acids
and caustics, and sludge. Wastes were disposed
of in tanks, barrels, seepage ponds, and open fill
operations. An estimated 210,000 cubic yards of
waste fill are in  place onsite.  As a result of
disposal  practices, contaminants have leached
through the soil and into the underlying glacial
aquifer and perched zone. Between 1970 and
1982, at least three onsite clean-up actions were
initiated. In 1970, the State required the removal
and offsite disposal of solid wastes, paint sludge,
and oils from seepage ponds and backfilling of
excavated pond areas. In 1978, industrial wastes
and degraded soil were excavated and stockpiled
onsite under a clay cover.   In 1982, the  site
owners removed three 10,000-gallon tanks, their
contents, and  surrounding contaminated soil,
along with contaminated fill material containing
an  unknown quantity of  drums.  This ROD
addresses the  waste mass and ground  water
contamination in the  perched  zone  and  the
glacial aquifer.   The primary contaminants of
concern affecting the  soil, debris, and ground
water are VOCs including benzene, PCE, TCE,
toluene, and xylenes; other organics including
PAHs,  PCBs,  and  pesticides;  and  metals
including arsenic, chromium, and lead.

SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
backfilling the northern portion of the fill area
with 125,000 cubic yards of fill; capping the
disposal area with a 14.9-acre multi-media cap;
installing  a slurry  wall  at  the western and
southern  boundary  of  the  disposal  area;
installing  ground water  recovery wells  or
trenches downgradient, and a collection transfer
system to deliver water to an onsite treatment
facility;  pretreating ground water onsite  to
remove  iron and manganese  using  aeration,
clarification, and filtration if needed, followed by
onsite treatment using air stripping and carbon
adsorption; using activated alumina to remove
fluoride from ground water, followed by offsite
discharge  of the treated water  to a  POTW;
monitoring ground  water;  and implementing
institutional controls including deed and ground
water use restrictions, and site access restrictions
such as  fencing.   The estimated present worth
cost for this remedial action is $30,720,300, which
includes a capital cost of $11,083300  and an
annual O&M cost of $1,277,400 for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Ground  water clean-up goals are based on State
health-based  standards  or method detection
limits (MDL), whichever is higher. Chemical-
specific  goals include benzene 1 ug/1 (State),
PCE 1 ug/1 (MDL), TCE 3 ug/1 (State), toluene
800 ug/1 (State),  xylenes 300 ug/1 (State), and
lead  5 ug/1 (State).

INSTITUTIONAL CONTROLS:

Deed and  ground water use restrictions will be
implemented onsite.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 325-acre National Presto Industries site is a
former munitions and metal-working facility in
Eau  Claire,  Chippewa  County,  Wisconsin,
adjacent to the town of Hallie. Surrounding land
use is light residential and commercial, and the
Chippewa River is located approximately 2 miles
north and west of the site. Lake Hallie is located
approximately  1 mile north of the site. The site
overlies a buried pre-glacial valley that serves as
a primary source of drinking water.  From 1942
until 1945, the site was a  government-owned,
contractor-operated producer of gunpowder,
small  arms,  and radar tubes.   The  site was
owned by National Presto Industries (NPI) since
1948. Initially, NPI manufactured cookware and
consumer products, and generated waste streams
consisting of metals,  oils,  grease,  and  spent
solvents during operations.  Also, beginning in
1951, artillery shell fuses and aircraft parts were
produced  by  NPI under  military  contracts.
Metal projectiles production began in 1954 under
separate  contracts.     Early  waste-handling
practices included  the  use of  dry wells and
seepage  pits  with  overflow  from  the  pits
discharged to a former sand and gravel pit via
gravity  flow.  Wastes also were  discharged
directly to the sand and gravel pit.  During the
1960's, three additional lagoons were constructed
as percolation ponds with the former sand and
gravel pit serving as a settling pond.  A major
waste stream generated from the defense-related
activities  was a  spent   forge  compound,
composed of mineral oil, graphite, VOCs, and
asphalt, which accounts for much of the sludge
in the bottom of one of the settling ponds.  From
1966 to 1969, the spent forge compound also was
landfilled onsite.  Subsequently, the spent forge
compound   was  recycled  as  part  of the
manufacturing  process.     Based   on  their
investigations,  EPA required NPI to provide
bottled water to an area in Hallie where private
wells  were  contaminated or  threatened  by
contamination from confirmed onsite sources. A
1990 ROD provided a permanent alternate water
supply in the  form  of hookups of affected
residents  and   businesses   to   municipal
distribution systems.  Further investigations by
EPA helped determine the presence of four
major contaminants migrating from the NPI site.
This ROD addresses management of migration
as an interim remedy.  A subsequent ROD will
address final remedies for both onsite source
control  and  ground  water.    The  primary
contaminants of concern affecting the ground
water are VOCs including PCE, TCA, and TCE.

SELECTED REMEDIAL ACTION:

The selected remedial action  for this  interim
remedy includes onsite pumping and treatment
of ground water  using two cascade aeration
units; discharging the treated water to onsite
storm sewers for transport to surface water;
conducting further studies to determine the need
for pretreatment of ground water; installing a
dedicated  pipe system   for  surface  water
discharge if the storm sewer system cannot be
utilized; and conducting long-term ground water
monitoring.  The estimated present  worth cost
for this remedial  action  is $1,290,000, which
includes an annual O&M cost of $163,000 for
years 0-1  and $104,000 for  years 2-30,

PERFORMANCE STANDARDS OR GOALS:

Treated water  must meet the requirements of
CWA Ambient Water Quality Criteria and State
standards for  discharge  to   surface  water.
Chemical-specific goals are not  provided, but
will  be  developed  as  part  of  subsequent
investigations.

                                     July 31,1991
SITE HISTORY/DESCRIPTION:

The Northside  Sanitary  Landfill  site  is  a
hazardous and  solid waste disposal facility in
Boone  County,  Indiana.    Adjacent  to the
Northside Sanitary Landfill (NSL) site is another
Superfund site, Enviro-Chem which, prior to this
ROD amendment, was to be remediated in a
combined remedy for both sites. Land use in the
area is agricultural to the south and east, and
residential  to  the   north  and  west,  with
approximately 50 residences located within one
mile of the sites.   Run-off  from the sites  is
collected in a ditch, which  flows offsite and
eventually empties into a reservoir that supplies
approximately 6 percent of the drinking water
for  the  City of  Indianapolis.   NSL  began
operating as a landfill between 1955 and 1962.
By 1981, NSL was  operating as a  hazardous
waste disposal facility and had accepted at least
16  million gallons  of hazardous substances
including paint  sludge, acids, spent acids, and
waste oil. Throughout its operation history, NSL
was allegedly  accepting  an  abundance  of
unapproved  waste   from  offsite   facilities
including Enviro-Chem,  an  adjacent  waste
recovery, reclamation and  brokering facility.
Additionally, EPA and the State cited  NSL for
numerous operational deficiencies.   In  1983,
NSL's  hazardous  waste  and  solid  waste
operators  permits  were  denied because  of
leachate  collection  problems, acceptance  of
unapproved waste,  and  deficiencies  in  its
closure,  post-closure,  and  ground   water
assessment  plans.  The State then ordered NSL
to perform several remedial measures including
installing a functioning leachate collection system
around  the entire  perimeter of the  landfill,
installing a slurry wall or another measure to
prevent ground  water migration, monitoring
ground water, and to discontinue acceptance of
solid waste except for that amount  needed to
adequately  contour  the site.  A 1987  ROD
provided a combined remedy for both  the NSL
and Enviro-Chem sites due to  their proximity
and other similarities. The 1987 ROD addressed
source control capping; pumping and  onsite
treatment of ground water; and implementing
deed and access restrictions. Since the signing of
the ROD, EPA and the State have been engaged
in negotiations  with the PRPs  for each site.
These negotiations have resulted in separate,
complimentary remedies and individual consent
decrees for each  site, and modifications  to the
original selected remedy. This ROD amendment
provides a comprehensive remedy and addresses
both  source  control   and  ground  water
remediation.   The  primary contaminants  of
concern affecting the ground water are  VOCs
including benzene, PCE, TCE, and toluene; other
organics including phenols;  metals including
arsenic, chromium, and lead; and oils.

SELECTED REMEDIAL ACTION:

The selected amended remedial action for this
site includes constructing a pipeline to  pump
ground water and  leachate offsite to  the city
sewer system at the city wastewater treatment
plant and constructing a hydraulic isolation wall
system south and west of  NSL  to  prevent
uncontaminated ground water from entering the
ground water leachate collection trench.  If for
any reason the city treatment plant cannot  be
used,   this  ROD   amendment  provides   a
contingency  for  onsite  treatment of ground
water, followed by onsite discharge to surface
water as specified in the 1987 ROD; treatment at
another wastewater treatment plant; or another
alternative consistent with the Clean Water Act.
Other remedial actions documented in  the 1987
ROD including construe ting a RCRA cap and gas
venting system; collecting leachate and ground
water in a  trench system; monitoring ground
water,  surface   water,  and  leachate;  and
implementing site access restrictions  are not
affected  by this  amendment.   The estimated
present worth cost for this remedial action

                                 September 5,1991
SITE HISTORY/DESCRIPTION:

The  2.6-acre Novaco Industries site is a one-
building site in Temperance, Michigan.  Land
use in the area is predominantly residential and
agricultural. The estimated 85 residences located
within 1/2 mile of the site use the underlying
sand/gravel  and  limestone aquifer  as  their
drinking water supply. In 1979, a chromic acid
leak occurred  from a 1,870-gallon underground
storage tank at Novaco, which led to chromium
contamination of an onsite well.  Subsequent
sampling from 1979 to 1982 detected chromium
in wells of properties adjacent to the site, and as
a result, new  wells  were  installed  in  the
uncontaminated lower  aquifer.   Later in 1979,
Novaco Industries began pumping and treatment
of 122,000 gallons of contaminated ground water,
removing 400  pounds of hexavalent chromium.
In 1983, the State sampled several residential
wells, and chromium  was not  detected above
background levels.   However, sampling  of
ground water monitoring wells in 1984 and 1985
revealed  chromium  contamination  levels  in
excess of the MCL. A 1986 ROD addressed a
final remedy for ground  water  contamination,
and provided  for ground water pumping and
treatment using electrochemical reduction/ion
exchange polishing, followed by onsite discharge
to surface water.  This ROD amends the 1986
ROD.  Pre-design studies  during 1988 have
determined  that  contaminant  levels  have
continued to decrease over time, and there is no
longer   any  indication  of   a   chromium
contaminant plume. Therefore, based on these
data, there  are no contaminants of concern
affecting the site.
SELECTED REMEDIAL ACTION:

The amended remedial action for this site is no
further  action.     Although   no  significant
contamination  is  present at  the  site,  EPA
recommends that nested wells be installed  and
ground water monitoring be  implemented to
evaluate the attenuation process.  However, if
contaminant levels for  hexavalent  chromium
exceed 50 ug/1 for two consecutive periods of
monitoring, the remedy from the 1986 ROD will
be implemented. There are no costs associated
with this no action  remedy.

                                  December 21,1990
 SITE HISTORY/DESCRIPTION:
 The 45-acre Oak Grove Sanitary Landfill is a
 former municipal and industrial  solid waste
 landfill in Oak Grove Township, Anoka County,
 Minnesota.  Land consists of low regions of
 uplands  and sand dunes  interspersed among
 numerous  lakes  and wetlands.   The nearby
 developed land  use in the area  is agricultural
 and residential.  The site overlies two aquifers,
 which are separated by a semi-confining layer.
 The deeper aquifer provides regional potable
 water and supplies many area residential wells.
 Landfill operations began in 1967 and continued
 until 1984,  when the operating license  was
 suspended. An estimated 2.5 million cubic yards
 of  waste  is present  in the landfill  including
 acidic  oil  sludge, paint  and solvent waste,
 foundry sands and sludge, inorganic acids, metal
 sludge, and chlorinated  and  unchlorinated
 organic   compounds   from  pesticide
 manufacturing.   In addition, lime  sludge  was
 used as a cover  material on two-thirds of the
 landfill. A 1988  ROD addressed  the sources of
 contamination  by containing the onsite waste
 and contaminated soil with a  cover.   EPA
 investigations  in 1989 determined  that  the
 contaminated shallow aquifer discharges directly
 to the  surface water of the adjoining wetlands
 where  ground water contamination is being
 reduced by natural attenuation, and thus, limits
 migration of contaminants to the  surface water.
 This  ROD   addresses   remediation   of
 contaminated shallow ground water, prevention
 of significant impacts on surface water from the
 discharge  of contaminated shallow  ground
 water,  and provides for continued use of the
 deep aquifer as a drinking water supply.  The
 primary contaminants of concern affecting the
 ground water  are VOCs  including  benzene,
 toluene, and xylenes; and metals including
arsenic.
 SELECTED REMEDIAL ACTION;
 The selected remedial action for this site includes
 long term monitoring of the shallow and deep
 aquifers, surface  water,  and sediment  at  a
 frequency of three times per year for the first
 year  and  semi-annually  thereafter;  natural
 attenuation  of   shallow   ground  water;
 abandoning   non-essential   wells;  and
 implementing  institutional controls  including
 ground water use  restrictions.  The  estimated
 present worth  cost for  this remedial action is
 $800,000, which includes an annual O&M cost of
 $90,000 for the first   year and $70,000 for
 subsequent years.

 PERFORMANCE STANDARDS OR  GOALS:
 Sediment, ground  water, and surface  water
 monitoring will assure that contaminant levels
 do not exceed SDWA MCLs, CWA AWQCs, and
 State surface water quality standards.

 INSTITUTIONAL CONTROLS:
 Institutional controls will be implemented for the
 placement of drinking water wells.

                                  September 30,1991
 SITE HISTORY/DESCRIPTION:

 The 5-acre Organic Chemicals site is an inactive
 solvent reclamation and chemicals manufacturing
 facility in Grandville, Kent County, Michigan.
 The  site includes several  onsite buildings,
 structures, above-ground  storage  tanks,  and
 drum storage  areas,  a  boiler  facility,  a
 wastewater  treatment facility, and a  seepage
 lagoon.  Wetlands potentially are located  1,900
 feet northwest of the site, and the Grand River is
 located 0.95 miles to the north of  the site.  A
 succession of petroleum-related industries leased
 the land for petroleum  refining from 1941 to
 1945,  followed  by  transport  and  storage
 operations  from  1945  to   1966.     Organic
 Chemicals Inc. (OCI), began site operations in
 1968. Company records show that between 1968
 and 1980,  process  waste  and  cooling water
 including  RCRA  hazardous   wastes  were
 discharged to the onsite seepage lagoon.   In
 1979, 2,200  gallons of  lacquer  thinner were
 spilled onto the ground onsite and, subsequently,
 some of the spilled thinner was recovered and
 disposed of onsite in the  seepage  lagoon.  In
 1980, discharges to the lagoon ceased,  and the
 company installed a wastewater pretreatment
 system, which discharged wastes to  the sanitary
 sewer system.   Subsequently,  in 1981,  the
 seepage  lagoon  sludge  was  excavated  and
 disposed of  offsite.  In 1983, EPA documented
 onsite soil   and  potential   ground  water
 contamination  resulting   from  the  solvent-
 contaminated seepage lagoon. Additionally, in
 1986, the State determined that OCI was illegally
 disposing of  sludge and  other  hazardous
 residuals  from  the  onsite  solvent  recovery
operations by placing these into drums or rolloff
containers along  with routine non-hazardous
waste materials.  Analysis of the  drum  and
container contents and soil samples from the
vicinity of these storage  units  revealed  the
presence of VOCs and other organics.
 During 1987, OCI,  as part of  a voluntary
 investigation,  discovered  and  removed  150
 buried  drums  containing sludge  and  liquid
 residues offsite, and identified further onsite soil
 contamination.  Federal and State investigations
 have determined that site contamination has
 resulted from past operation  of the  seepage
 lagoon by OCI, chemical spills at the  site and
 past oil-related activities.  EPA has divided the
 remediation into  two response actions.  This
 ROD addresses contamination  in the  upper
 ground water system, as an interim remedy. A
 future ROD will constitute the final response at
 the  site by addressing the  remaining  onsite
 ground water and soil contamination.  The
 primary contaminants of concern affecting the
 ground water are VOCs  including  benzene,
 toluene,  and  xylenes;  and other  organics
 including PAHs and pesticides.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 onsite pumping and treatment of ground water
 using  a treatment system  consisting  of an
 equalization/sedimentation basin, two granular
 activated carbon  vessels, and an air  stripper
 polishing unit;  discharging the treated  water
 onsite to the Grand River; disposing of treatment
 carbon residuals in an offsite landfill; conducting
 a treatability study and pump test to determine
 the proper treatment train  and pumping rates;
 and  ground water monitoring.  The estimated
 present  worth cost for  this  interim remedial
 action is $5,931,000, which includes an annual
 O&M cost of $317,000.

 PERFORMANCE STANDARDS OR GOALS:

This  remedial action  is only part of a  total
remedial action and will attain  ground  water
clean-up ARARs during future response actions.

                                    June 28,1991
SITE HISTORY/DESCRIPTION:

The Ossineke Ground Water Contamination site
is an area overlying a contaminated aquifer in
Ossineke, Alpena County, Michigan. Land use
in the area is predominantly residential and
commercial, with wetlands  areas bordering the
west and northeast boundaries of the site. The
site hydrogeology is characterized  by an upper
aquifer  and lower confined  aquifer, both  of
which supply drinking water to local residents.
Historically, there have  been  two  contaminant
source areas of concern within Ossineke.  Area 1
is in the center of the Town of Ossineke where
two gas stations  are  located, consisting  of
underground storage tanks,  and  a  former
automobile rustproofing shop.  In 1973,  the
rustproofing shop closed, the  garage floor was
reportedly  washed with chlorinated solvents,
and the residue was disposed  of on the ground
behind the  shop.  Area 2 is a laundry and dry
cleaning facility that has an  associated  wash
water pond containing chlorinated hydrocarbons
and VOCs.  In 1977, citizen complaints about
odors from drinking  water obtained from  the
upper  aquifer prompted a number of State
investigations, which  revealed  extensive onsite
ground  water contamination in  the  upper
aquifer.  Consequently, the State advised all
users of the upper aquifer  to stop using their
wells. In 1982, the State discovered that a snow
plow  had  hit a  gasoline  pump  causing an
unknown  amount of gasoline to  spill and,
subsequently, contaminate  the basements  of
several businesses.  In 1986, the State replaced
the residential wells affected by ground water
contamination.  Because the  contaminants  of
concern have been confirmed to be related  to
petroleum  releases from underground  storage
tanks, the Superfund program does not have the
authority to address cleanup under CERCLA.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site is that
no  further  action be  taken  under CERCLA
Section 101, and that the site be transferred to
the EPA Office of Underground Storage Tanks
(OUST). In  1990, a formal transfer of the project
from OSWER to OUST occurred.  There are no
costs associated with this no action remedy.

                                     June  28,1991
SITE HISTORY/DESCRIPTION:

The 100-acre Pagel's Pit site is an active sanitary
landfill facility in a predominantly rural area of
Winnebago County, Illinois.  Surrounding land
use  is  mixed  agricultural,  rural residential,
commercial, and industrial. The site is bounded
on  the west  by  Killbuck  Creek.    Another
Superfund site, Acme Solvent Reclaiming, Inc., is
located east and upgradient of Pagel's Pit. The
Acme Solvent  site  has been shown  to  have
contaminated   the   ground  water   in  the
downgradient  direction.   The landfill at the
Pagel's  Pit site  is a former sand and gravel
quarry with a sealed asphalt liner that covers
about 47  acres.   The landfill,  which began
operating in 1972, accepted primarily municipal
waste, sewage sludge, and limited amounts of
Illinois special  wastes.   Beginning in 1980, a
network of gas extraction wells was installed to
remove  landfill  gas  that is  generated  by the
wastes.  Gas collected from the wells is used as
a fuel  source  for a  sludge  drying  operation.
Some of these wells  also are used for leachate
collection along with the manholes installed in
the landfill.  In 1990, it was estimated that the
landfill contained about 4,700,000 cubic yards of
waste and had 5 to 7 years of operating capacity
remaining.   It  has  been  determined  that the
landfill has caused contamination of the ground
water.  This ROD addresses the landfill wastes
and  contaminated   ground   water  at  the
downgradient side of the site as operable unit 1
(OU1).  A future ROD will address ground water
contamination in the southeast corner of the site
that is currently undergoing further study. The
primary contaminants of concern  affecting the
ground   water  are  VOCs  including   1,2-
dichloroethene and vinyl chloride; and metals
including arsenic, barium, manganese, thallium
and zinc.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
constructing a sanitary  landfill cover for the
waste disposal area; pumping ground  water
along the  west side of  the site; removing
inorganics by  treating  with ion exchange or
coagulation/flocculation, if necessary, prior to
onsite treatment using carbon adsorption or air
stripping, followed by carbon polishing of the
treated water,  with onsite  discharge to surface
water;  removing  spent  carbon  offsite  for
regeneration or disposal; extracting and treating
leachate offsite at a POTW; extracting landfill gas
and using the gas for fuel, or flaring the gas;
monitoring ground  water, leachate, and  air;
maintaining all remedial action components; and
implementing  institutional  controls including
deed restrictions. The estimated present worth
cost  for  this  remedial action is  $9,800,000 or
$11,000,000,  which  includes O&M  costs  of
$310,000 or $248,000 for 30 years, depending on
the process selected.

PERFORMANCE STANDARDS OR GOALS:

Ground  water  goals are  based  on currently
promulgated MCLs or non-zero MCLGs, (except
for arsenic and 1,1,-dichloroethene) or a risk
level of 10"5 or an HI=1 for contaminants without
MCLs.    Chemical-specific  goals   were  not
provided.

INSTITUTIONAL CONTROLS:

Deed restrictions may be implemented to limit
the development of property, and the placement
of new wells on the property and adjacent to the
site.

                     PINE BEND  SANITARY LANDFILL, MN
                                 September 30,1991
 SITE HISTORY/DESCRIPTION:

 The Pine Bend Sanitary Landfill site is located
 1 mile east of the Mississippi River in Inver
 Grove Heights,  Dakota  County,  Minnesota.
 Land use in the area is residential and industrial.
 The terrain is generally flat and  contains an
 immature drainage system  resulting in onsite
 numerous ponds and wetlands.   The site is
 composed of  two landfills:  the 255-acre active
 Pine  Bend Sanitary  Landfill  (PBSL)  and the
 inactive 52-acre  Crosby  American  Demolition
 Landfill (CADL). PBSL began operation in 1971
 as a mixed municipal solid waste facility, CADL
 accepted  compressed bales  of municipal  solid
 wastes from 1971 to 1974, and later, from 1976 to
 1989   also   accepted  demolition  wastes.
 Hydrogeologic data from the site show that the
 two landfills  are considered one site because
 their ground water plumes commingle within a
 common surficial aquifer.  The resulting plume
 moves through  the  surficial  aquifer and is
 believed   to  eventually   discharge  to  the
 Mississippi River via springs in the river bottom.
 In 1983, elevated levels of VOCs were detected
 in the surficial ground water beneath the  site,
 and  low  levels  of VOCs were identified in
 numerous  downgradient   commercial   and
 residential wells.  This contamination is believed
 to be  the  result of  precipitation  infiltrating
 through the permeable  landfill material  and
 coming in contact with buried waste. Since 1986,
 at the request of  the State, CADL has provided
 bottled water  to  residences  with contaminated
 wells to minimize the risk of VOC-contamination
 migrating from the PBSL/CADL site. This ROD
 addresses ground water contamination as the
 first of three operable units (OUs). Future RODs
 will address source control and final remediation
of ground water.  The primary contaminants of
concern affecting the  site are VOCs including
benzene, PCE, TCE, and toluene.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
providing a permanent alternative water supply
by extending the existing Inver Grove Heights
municipal water supply; connecting impacted or
potentially impacted premises to the municipal
water  supply;  and permanently sealing  the
potentially affected onsite private water supply
wells. The estimated present worth cost for this
remedial action is $2,649,499, which includes an
annual O&M cost of $30,350 for 30 years.

                                    March 28,1991
 SITE HISTORY/DESCRIPTION:

 The 33-acre Rasmussen's Dump site is a former
 industrial and domestic waste disposal area in
 Green  Oak  Township,  Livingston  County,
 Michigan. Surrounding land is  predominantly
 wooded with some residential and agricultural
 development.  Area residents rely solely on the
 aquifer  underlying the site for  their  drinking
 water  supply.   The  site is  adjacent to  the
 Spiegelberg  Landfill, another Superfund  site.
 During  the 1960's and early 1970's, domestic,
 industrial, and drummed hazardous wastes were
 disposed of on approximately one-third of the
 site.  Many  incidences of  onsite burning of
 wastes were reported during operational years of
 the facility.  Landfill operations  ended in 1977
 without complying with State laws on proper
 capping or closure.  Sand and gravel mining,
 which began  following  site  closure, caused
 unearthed waste fill and drummed wastes to be
 redistributed around the site. In  1981,  the State
 detected  low  levels   of   ground   water
 contamination  onsite.    This  contamination
 includes: two onsite contaminated ground water
 plumes  and four areas of  soil  contamination
 referred to as the Top of the Municipal Landfill
 (TML),  the   Northeast  Buried   Drum  Area
 (NEBD), the Industrial Waste Area (IW), and the
 Probable Drum Storage, Leakage, Disposal Area
 (PDSLD).  In 1984, EPA removed  approximately
 3,000   drums  and   250  cubic  yards  of
 contaminated  onsite soil.   In 1990, the PRPs
 removed an additional 650 onsite drums, waste,
and associated visibly contaminated soil from the
TML, NEBD, and IW areas, thereby reducing the
 risk posed by the areas. Testing in the PDSLD
area indicated that soil contamination resulting
 from drum leakage continues to migrate into the
soil directly above the ground water table or into
the ground water itself, and poses a continuing
ground water threat. This ROD provides a final
remedy for onsite contaminated soil and ground
Water.   The primary contaminants of concern
affecting the soil and ground water are VOCs
including benzene, TCE, toluene, and xylenes;
other organics  including ketones,  chlorinated
hydrocarbons, and phenols; and metals including
cadmium, and lead,

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
capping the waste in the TML and NEBD areas,
and removing  and disposing of waste drums
unearthed during cap construction  offsite  at a
RCRA facility;  ground  water pumping  and
treatment using chemical precipitation followed
by   pH  adjustment   to   remove   metal
contaminants, a biological treatment system to
remove organic ground water contaminants, and
air  stripping and granular activated carbon to
remove   residual  organic   contaminants  as
necessary; discharging the treated ground water
onsite through a seepage basin in  the IW  and
PDSLD  areas  to  flush area  soil;   monitoring
ground   water;  continuing  residential  well
sampling in conjunction with sampling for the
adjacent  Spiegelberg   Superfund   site;   and
implementing  institutional  controls including
deed restrictions, and site access restrictions such
as fencing.  The estimated capital cost for this
remedial action is  $7,320,000, with an annual
O&M cost of $4,580,000.

PERFORMANCE STANDARDS OR GOALS:

Soil contaminant levels in the PDSLD/IW areas
will be reduced to less than 20 times the ground
water clean-up  level for  each chemical; or leach
tests performed on the PDSLD/IW soil must
produce leachate with concentrations below the
ground water clean-up  levels.  Ground water
clean-up goals  are  based on a 10"6  cancer  risk
level,  Human  Life Cycle Safe Concentrations
(HLSC) detection limits, Taste and Odor (T&O)
Threshold,  State  standards,  and  risk-   and
health-based criteria. Chemical-specific goals for

                                    June 14,1991
SITE HISTORY/DESCRIPTION:

The  2-  to 3-square mile Southeast Rockford
Groundwater Contamination site is a residential
area   with  contaminated  private  wells  in
Winnebago County, Rockford, Illinois. The site
is in  a predominantly urban residential area that
includes  retail  and  commercial  operations.
Surrounding land use is industrial.   During
sampling from 1981 to 1984, the City of Rockford
identified elevated VOC levels in ground water.
Subsequently, in  1985, four  municipal  wells
including Municipal Well #35 and several private
wells were closed. In 1984, after plating waste
was  illegally disposed  of  in  a  well,  EPA
conducted   investigations   that  identified
contamination  by  VOCs and  inorganics in
municipal and private wells. From 1986 to 1989,
further EPA investigations defined a 1.2-mile
contaminated area. In 1989,  EPA initiated an
emergency  action   including   temporarily
providing bottled  water  and  attaching carbon
filters at  affected residences and ultimately
connecting wells to the city water supply if VOC
contamination  exceeded   25  percent of the
Removal  Action  Level  (RAL).    This  ROD
addresses the elimination of risk to residents of
the Southeast Rockford area due to contaminated
ground water. A subsequent ROD will address
remediation of the contaminated ground water
plume.  The primary contaminants of concern
affecting the  ground water are VOCs including
PCE  and TCE.

SELECTED REMEDIAL ACTION:

The  selected remedial  action for this interim
remedy includes providing an alternate water
supply by constructing and  extending  water
niains, and installing connections and service to
the city distribution system for affected residents;
reactivating   Municipal   Well   #35   after
constructing a granular activated carbon water
treatment facility at the well; and abandoning
contaminated  private  wells.   The  estimated
present worth cost for this remedial action is
$5,820,000, which includes an annual O&M cost
of $436,800 for years 1-5 and $58,800 for years
6-30.

                                   August  13,1991
SITE HISTORY/DESCRIPTION:

The 159-acre South Macomb Disposal #9,9A site
contains  two  inactive  municipal  landfills in
Macomb Township, Macomb County, Michigan,
Land   use   in  the  area  is  predominantly
agricultural  and rural, with several  adjacent
residences.  A small stream, the McBride Drain,
runs along the western and southern boundaries
of the site, and there is a possible wetlands area
located at the site. Until 1989, the estimated 34
residents in  the immediate vicinity of the site
used   shallow   and   intermediate  aquifers
associated with contamination from landfills as
their drinking water supply. From 1968 to 1975,
South Macomb Disposal Authority (SMDA), a
municipal corporation, used the site to facilitate
the  management  and  disposal of municipal
refuse for five towns in Macomb County. SMDA
acquired  the 75-acre area #9 in 1968, accepted
680,000 cubic yards of municipal waste, and
capped the area with soil in 1971. Subsequently,
SMDA acquired the adjacent 84-acre area 9A in
1970,  filled  it  with 1,200,000  cubic yards of
municipal waste, and  capped the  area with a
mixture of sand, clay and silt  in  1975.  As a
result of reported fish kills and continued reports
of leachate  seepage  into McBride Drain,  a
number of State investigations between 1976 and
1982 verified that the site was the source of the
leachate  problem and  prompted  SMDA to
upgrade and expand leachate collection systems
along various porh'ons of area 9A. From 1983 to
1984,   the  State  investigations   detected
VOC-contaminated ground water  in several
residential wells  near the site.  Consequently,
from  1985  to  1988,  SMDA  constructed  an
additional leachate collection system on area #9,
and a slurry  wall across the northern portion of
area #9. In 1989, Macomb Township connected
residences near the site to the municipal water
supply.     This  ROD  addresses   onsite
contaminated ground water as  operable unit 1
(OUl). A future ROD will address the landfill
contents as OU2. The primary contaminants of
concern affecting the ground water are VOCs
including benzene and  toluene;  other organics
including phenols; and metals including arsenic
and chromium.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
installing extraction wells in the intermediate
aquifer, both  within  and  outside  the  site
boundary and subsurface drains  in the  shallow
aquifer along the periphery of the waste deposits
in both sites #9 and 9A; collecting ground water
and  leachate in a  series of collection sumps,
followed by pumping to the onsite ground water
treatment  system;  treating  the  contaminated
ground water onsite using air stripping, followed
by   granular  activated  carbon,   oxidation/
precipitation, and granular media filtration, with
onsite discharge of the treated water to McBride
Drain;  disposing  of any treatment residuals
offsite; extending the existing slurry wall along
the east side of area #9; providing a municipal
water supply to any residences within a one-half
mile radius of  the site  that are not currently
attached; conducting long-term  monitoring  of
ground  water, surface water,  sediment  of
McBride Drain, leachate, air, and  residential
wells; and  implementing institutional controls
including deed  and ground water restrictions,
and  site access restrictions  including  fencing.
The  estimated  present worth  cost  for  this
remedial action is $9,264,000, which includes an
annual O&M cost of $224,000.

PERFORMANCE STANDARDS OR GOALS;

Chemical-specific ground water clean-up goals

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The  27-acre Stoughton City  Landfill  site  is a
former waste disposal facility in Stoughton, Dane
County,  Wisconsin.    The  site   was   an
uncontrolled dump site from 1952 to 1969, and
later  from  1969  to  1977  operated  as  a
State-licensed landfill  covering approximately
15 acres.  Land use in the area is predominantly
agricultural  and  residential,   with  several
wetlands areas located adjacent to the site. In
addition, part of the site lies within the 100-year
floodplain of the Yahara River, located west of
the site.  From 1954 until  1962, liquid wastes
Were routinely poured over garbage and burned.
In addition, some liquid wastes were poured
down  holes  drilled  to  test  auger drilling
equipment. From 1969 to 1977, both solid and
liquid municipal wastes were disposed of at the
Stoughton Landfill.  In 1977,  the State required
that  the  site  be closed and initiated closure
activities that  included constructing a  trash
transfer station, placing cover materials, applying
topsoil, and seeding. As a result of improper
disposal activities, a number of investigations
were conducted  by the State  and EPA  that
revealed ground water contamination  resulting
from leachate discharge and surface water  run-
off from the landfill.  This  ROD addresses soil
and  ground water contaminated by  leaching
tandfilled waste.  The primary contaminants of
concern affecting the soil,  debris, and ground
water   are  VOCs   including  benzene,
tetrahydrofurans  (THF), toluene, and xylenes;
pther organics including  PAHs; and metals
Deluding arsenic, chromium,  and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
placing a solid waste disposal facility cap over
the site; excavating wastes  in  contact with
ground water  along  the southeastern  and
northeastern   sections   of   the  site   and
consolidating these  wastes   under  the cap;
pumping and treatment of contaminated ground
water unless additional monitoring indicates that
ground water extraction  is  not  required  to
achieve compliance with State quality standards,
and subsequent onsite discharge of the treated
ground water to the Yahara River in compliance
with NPDES  effluent limitations;  long-term
monitoring of ground water; and implementing
institutional controls and site security measures
including fencing the entire site perimeter. The
estimated present worth cost for  this remedial
action  is $7,546,000,  which includes an annual
O&M cost of $329,600 for years 0-5 and $146,600
for years 6-30.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water clean-up goals
are based on State  Preventive Action  Limits
(PALs), and include THF 10 ug/1.

INSTITUTIONAL CONTROLS:

Land use restrictions  will be  implemented  to
prevent the installation of a well within 1,200
feet of the property boundary and residential
development of the site.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 5-square-mile Sturgis Municipal Wells site is
an active  municipal well field in Sturgis, St.
Joseph County, Michigan. Land use in the area
is   predominantly  mixed   industrial   and
residential, with several wetlands areas located
near the site.  The estimated 10,000 residents of
Sturgis use the intermediate and deep aquifers as
their drinking water supply.  The site includes
the former Wade Electric facility, which closed in
1966 and burned down in 1974, and the Kirsch
Company, which operated as a manufacturing
facility until 1980.  These two properties have
been identified as two  source areas responsible
for the ground  water  contamination in the
aquifer used  for the municipal  water  supply.
State investigations starting in 1982  identified
contaminated  soil  and  VOC-contaminated
ground water onsite and extensive ground water
contamination in various wells throughout the
city.  This ROD addresses final remediation of
soil  and   ground  water.    The  primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, PCE,
and TCE; and other organics including PAHs.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating VOC-contaminated soil  using vapor
extraction,  followed  by  activated  carbon
adsorption to capture off-gases; regenerating
carbon offsite; excavating and disposing of of fsite
10,890  cubic  yards  of  low   level  PAH-
contaminated soil (10,000 cubic yards from the
Kirsch property and 890 cubic yards from the
Wade property); onsite pumping and treatment
of ground water using air stripping, followed by
vapor phase granular activated carbon to treat
off-gases; discharging the treated water onsite
either to surface water via a storm sewer or
making  the water available  for  use by the
municipal  water   system;   ground   water
monitoring;  and  implementing  institutional
controls, and site access restrictions including
fencing.     A  contingency  plan   would  be
developed to allow for the rapid installation of a
mobile water supply treatment system, should it
be required at any of  the existing municipal
supply wells.  The estimated present worth cost
for  this remedial action  is $13,810,000  for
discharge of treated ground  water to a storm
sewer, which includes an annual O&M cost of
$644,600 for years 0-3 and $598,000 for years
4-30.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil clean-up goals for VOCs
are based on State standards, and include PCE
14 ug/kg and TCE 60 ug/kg.  Soil containing
PAHs will be excavated to 330 mg/kg, based on
State standards. Chemical-specific ground water
clean-up goals are based on State standards, and
include  benzene 1 ug/1, PCE 1 ug/1, and TCE
3 ug/1.

INSTITUTIONAL CONTROLS;

Ground   water   use  restrictions  will   be
implemented  to prevent further installation of
wells in  the City of Sturgis pending restoration
of the well field and associated aquifers.

 SUMMIT NATIONAL LIQUID DISPOSAL SERVICE (AMENDMENT), OH
                                  November 2,1990
 SITE HISTORY/DESCRIPTION:

 The 11.5-acre Summit National Liquid Disposal
 Service site is a former liquid waste disposal
 facility in rural Deerfield Township, Ohio. The
 site contains two ponds, an inactive incinerator,
 and several vacant buildings.  Surrounding the
 site are several residences,  two landfills, light
 industries,  and farmland.  Fifteen to twenty
 residential wells are located  within 1,000 feet of
 the site.  From 1973 to 1978, Summit National
 operated a solvent recycling and waste disposal
 facility onsite. Oil, resins, sludge, pesticide and
 plating wastes, and  other liquid wastes were
 stored, incinerated, and buried or dumped onsite
 during facility operations.  In 1978,  the State
 ordered  Summit  National  to stop  accepting
 waste material and  to remove all liquid waste
 from the site. In 1980, EPA removed three bulk
 tanks,  which  contained  approximately  7,500
 gallons of hexachlorocyclopentadiene along with
 contaminated  soil,  and  treated  some
 contaminated water. In  1981, the State and eight
 of the potentially responsible  parties  removed
 additional drums, tanks, surface debris, and a
 small amount of contaminated soil from the site.
 Subsequently, EPA took  interim measures to
 control the migration of contaminants offsite and
 excavated an underground storage tank. During
 the RI/FS,  conducted from  1984 to 1987, EPA
 documented  onsite  contamination   of   soil,
 sediment, ground water, and surface water by a
 variety of organic  and inorganic compounds.
 Contaminated   property   outside   the   site
 perimeters also was found. This ROD amends a
 1988 ROD  that provided for  remediation  of
contaminated soil,  sediment,  debris, ground
 water, and surface water.  Based on further site
 investigations, EPA modified their original goal
of containing contaminated media to one  of
long-term cleanup at the site.  In both the 1990
proposed remedy for this ROD amendment and
 the 1988 ROD, the remedy for the most highly
contaminated soil and  sediment is excavation
and treatment;  however, the ground water
extraction method in the 1990 proposed remedy
was significantly different from the 1988 ROD
and employed a different  technology that will
result in long-term soil cleaning, thus eliminating
the need for the containment of  contaminants
with a slurry  wall  and  multi-layer cap as
provided  in the 1988 ROD.    The primary
contaminants of  concern affecting   the  soil,
sediment,  debris, ground  water, and surface
water  are  VOCs including benzene,  TCE,
toluene, and xylenes; other organics including
PAHs,  PCBs, and phenols; and metals including
arsenic and chromium.

SELECTED REMEDIAL ACTION:

The selected amended remedial action for this
site  includes expanding  site  boundaries to
include contaminated  areas  along  the  site
perimeters; excavating and incinerating onsite
24,000 cubic yards of soil excavated to a depth of
2 feet,  4,000 cubic yards of sediment  from the
site  perimeter,  drainage   ditches and  offsite
ponds, and 900 to 1,600 buried drums, followed
by  backfilling  the  residual  ash onsite, or
disposing of the ash offsite in a RCRA facility if
the waste does not  meet EPA  performance
standards;  regrading  the  site;  installing  a
permeable soil cover over 10.6 acres of the site
with gas  vents  for treating  and monitoring
potential air emissions;  dismantling  and/or
demolishing all onsite structures, and  disposing
of debris onsite; collecting ground water from
the upper aquifer via pipes and drains,  and
constructing additional extraction wells in the
lower aquifer to augment the pipe and drain
system, followed by  treating ground water
onsite;  collecting  and treating onsite surface
water from the two onsite ponds  and  drainage
ditches   using    precipitation,   flocculation,
coagulation,  oil and water separation, filtration,
and carbon adsorption using a pipe and drain
collection system; excavating sediment after
                                            357

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 9.5-acre Thermo Chem site is composed of
an   inactive  solvent  and   chemical   waste
reprocessing, refining, and incineration facility,
and an inactive waste hauling facility in Egelston
Township, Muskegon  County, Michigan.  The
area surrounding the site consists of residential
areas,  light  manufacturing   and  commercial
buildings, and undeveloped woodlands. The site
is adjacent to two other Superfund sites: the SCA
Independent Landfill site, and the Bofors Nobel
site, which are located approximately 1,800 feet
south and 1.25 miles east of the site, respectively.
Site features include a warehouse, an incinerator,
above-ground storage  tanks, a laboratory, and
process buildings and associated lagoons.  A
trout  stream,  Black   Creek,  is  located
approximately 1,500 feet  south of the site and
forms a broad and flat wetland.  From 1969 to
1980, Thermo Chem  received,  distilled, and
regenerated  solvents,   paint   wastes,   and
antifreeze into usable  solvents.  Unrecoverable
materials and by-products including sludge and
residues were incinerated onsite.  The Thomas
Solvent Company, which lies adjacent to, and is
owned by Thermo Chem, has been included as
part of the site because it is suspected to be a
source of ground  water contamination.   The
Thomas Solvent  Company was operated  as  a
hazardous waste hauling facility for Thermo
Chem  and collected waste for recycling and
returned the material to customers. Wastewater
generated   from  the  distillation   and
equipment-cleaning  process  at  Thermo-Chem
was discharged  onsite into  a series of  three
interconnected  lagoons.      In   addition,
approximately 3,500 drums containing raw and
recycled  materials   were  stored  in  an  onsite
underground storage tank farm area during the
years of  operation.   Former  onsite personnel
indicated that sludge was occasionally buried
onsite, and that onsite chemical spills frequently
occurred.  In response to investigation activities
during  1988  and 1991, EPA  conducted  an
emergency removal  of  drums and  materials
containing  hazardous   waste.      Federal
investigations in 1990 indicated that contaminant
releases were  one source of  ground  water
contamination. This ROD addresses the source
of contamination by remediation of soil, sludge,
debris, and ground water up to the point where
ground water  discharges into  Black Creek as
operable unit  1  (OU1).   A future  ROD will
address OU2, the contamination problems within
Black Creek and  ground water contamination
south of Black Creek. The primary contaminants
of concern affecting the soil, sludge, debris, and
ground water are VOCs  including benzene,
toluene, and xylenes; other organics including
PAHs, PCBs, and  pesticides; metals including
arsenic,  chromium,   and  lead;  and  other
inorganics.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating, removing, and  incinerating offsite
approximately  2,000  cubic  yards  of soil and
sludge; treating and disposing offsite any ash or
residuals produced from  offsite  incineration;
installing  an  in-situ  vapor  extraction  (ISVE)
system and treating  onsite approximately 9.5
acres of remaining contaminated soil; conducting
a treatability study to determine the feasibility of
enhancing the natural biodegradation of organic
compounds in  the   soil   undergoing  ISVE
treatment;  treating gases  emitted  from  the
extraction  wells using a  fume-rich incinerator;
treating liquid from the vapor extraction process
onsite; covering  the  site with clean soil and
vegetation,  if   necessary;  decontaminating,
demolishing, and disposing of offsite all onsite
buildings and structures; onsite pumping and

                                     June 28,1991
 SITE HISTORY/DESCRIPTION:

 The Verona Well Field site consists of a well
 field, three contaminant sources, and the ground
 water between the  source areas and the well
 field in Battle Creek, Calhoun County, Michigan.
 Surrounding land use is mixed residential and
 industrial.   Part of the site  lies  within  the
 100-year floodplain  of the Battle Creek River,
 which runs southwesterly through the site. The
 site overlies a surficial glacial aquifer and a
 deeper bedrock aquifer, both of which are local
 sources of drinking water. The estimated 53,000
 people who reside  within  the City of  Battle
 Creek and several surrounding communities and
 industries use  the Verona Well Field, screened
 within the bedrock aquifer, as their primary
 drinking water source. From 1964 until 1984, the
 Thomas  Solvent  Company  stored, blended,
 repackaged,  distributed,  and  disposed  of
 industrial solvents at both their  Thomas Solvent
 Raymond Road (TSRR) facility and their Thomas
 Solvent Annex facility.  Three  source areas of
 contamination   have  been  identified   onsite,
 including the TSRR  and Annex facilities, and a
 paint shop in the Grand Trunk Western Railroad
 (GTWRR)   marshalling   switching   yard.
 Contamination of the onsite soil has resulted
 from  surface spills, leaking drums, and  leaking
 underground storage tanks.  During the 1960's
 and 1970's, the paint shop in a car department at
 the GTWRR used solvents for  degreasing and
 cleaning purposes.   Spent solvents were either
 disposed of directly on the ground or in a drum
 pit outside the car department building.  In 1981,
ground water contamination was discovered at
 the  site,  which  resulted in  a  number  of
investigations conducted by the State and EPA.
In 1984,  an Initial  Remedial   Measure (IRM)
provided for the conversion of 12  production
wells  into purge wells, and the installation of
3 new production wells and an  air stripper. A
 1985 ROD addressed remediation of soil and
ground water at the TSRR facility, and provided
for treatment of contaminated soil using vapor
extraction with off-gas treatment, and pumping
and treatment of contaminated  ground water.
This  ROD  addresses  the  second  and  final
operable  unit  for soil  and  ground water
contamination at  the  site.    The  primary
contaminants of concern affecting the soil and
ground water are VOCs including benzene, PCE,
TCE,  toluene,  and  xylenes;  other organics
including phenols; and metals including arsenic
and chromium.

SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
treating soil at the Thomas Solvent Annex and
the GTWRR paint  shop  area using in-situ soil
vapor extraction; continuing the operation of the
existing purge wells and air stripper; installing
additional purge wells, and  treating extracted
ground water from the  well field  and source
areas onsite using air stripping and vapor phase
carbon adsorption, with onsite  discharge  to

                    WASHINGTON COUNTY LANDFILL, MN
                                 November 15,1990
 SITE HISTORY/DESCRIPTION:

 The 40-acre Washington County Landfill site is
 an  inactive  sanitary  landfill in Lake  Elmo,
 Washington County, Minnesota. Land use in the
 area   is  predominantly   residential   and
 agricultural.  Lake Jane is located 250 feet north
 of the  landfill.  The site overlies the St. Peter
 Sandstone and  Prairie du  Chien  Dolomite
 aquifers, both of which are sources of drinking
 water  for an estimated 3,000 residents  living
 within 3 miles of the site.  From  1969 to 1975,
 Washington and Ramsey counties used the site
 as a sanitary landfill.  The landfill is located in
 an old gravel pit, and  was constructed without
 a liner. An area of approximately 35 acres  was
 filled with solid waste to an average depth of
 approximately 30 feet.  About 2.57 million cubic
 yards of solid waste, excluding cover material,
 were disposed of in the landfill. The waste  was
 primarily composed of residential waste with
 smaller amounts of demolition and commercial
 waste.   Monitoring  by Washington County in
 1981 revealed low-level VOC contamination,
 which  poses a health  risk based  on long-term
 ingestion of ground water. In 1983, four nearby
 private wells also were found to contain  low
 levels  of  VOCs, and drinking  water well
 advisories were issued. A 1984 ROD provided
 for  the installation and operation of a ground
 water  gradient  control and spray-irrigation
 treatment system at the landfill. It also provided
a safe drinking  water supply to residents with
drinking water well advisories and initiated
monitoring of the ground water gradient control
system. This ROD addresses a final remedy for
drinking water supply as part  of a second
operable unit.   The primary  contaminants of
concern affecting the ground water are  VOCs
including benzene, PCE, TCE, and xylenes.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
providing a  municipal  drinking water supply
system to supply drinking water to  10 homes
with private wells that have been affected by the
contaminant plume; and continued operation of
the gradient control well and  spray-irrigation
treatment system for the first operable  unit,
which consists of four  gradient control wells,
two onsite spray-irrigation treatment areas, and
onsite discharge to surface water. The estimated
present  worth cost of  this remedial action is
$400,000, which includes an annual O&M cost of
$2,469.

PERFORMANCE STANDARDS OR  GOALS:

Chemical-specific ground water clean-up goals
are based on Recommended  Allowable Limits
(RALs) established by  the State and include
benzene 7 ug/1, PCE 6.6 ug/1, TCE 31  ug/1, and

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 100-acre Zanesville Well Field  site is an
active manufacturing and municipal well site in
Zanesville, Ohio.  The site is composed of the
28-acre United Technologies Automotive (UTA)
facility and the 72-acre City of Zanesville Well
Field.  Land use in the area is predominantly
residential and industrial.   The  Muskingum
River borders  the  manufacturing  area on the
west and the well field on the east From 1929
to the present the  UTA property was used for
various  types  of  manufacturing  activities.
During the early 1970's, a 10-foot wide, 75-foot
deep  onsite  well  was  filled  in  by  using
demolition material and approximately 121 steel
drums,   some  of  which  contained   TCE.
Additionally, TCE-based solvents were stored in
a bulk storage  tank adjacent to the well, and
other waste solvents  were  stored  in  drums
located near storm sewer  basins.   After EPA
investigations   in  1981   revealed   VOC
contamination in onsite ground water, the use of
three  wells at  the Zanesville Municipal Well
Field was discontinued.  In 1983, approximately
145 tons of waste were removed from the filled
in well by UTA when the  well was properly
abandoned and sealed.  Two of the three onsite
wells  are currently part of a  ground  water
interceptor  system,   in   which  extracted
contaminated water is discharged directly to the
Muskingum River.    This ROD  addresses
contaminated soil  on  and  around  the UTA
facility, contaminated ground water under and
around the Zanesville Well Field and the UTA
facility, and the sources of the ground water
contamination.  The primary contaminants  of
concern affecting the soil and ground water are
VOCs  including  TCE  and  dichloroethylene;
metals including arsenic, chromium, and lead;
and other inorganics.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating approximately 36,000 cubic yards of soil
and source areas contaminated by VOCs using
in-situ vapor  extraction, followed by  activated
carbon  to control  off-gases; regenerating the
spent carbon from  the  air stripping process;
treating  onsite   1,800  cubic   yards  of
inorganic-contaminated soil using soil  washing;
replacing the treated soil onsite; disposing of the
concentrated  waste and  treatment  residuals
offsite,  with   further   treatment,  if  needed;
pumping and onsite treatment of contaminated
ground  water  using  air  stripping;   and
implementing site access restrictions to the UTA
property, and to the interceptor wells, discharge
pipes,  and treatment  facilities located in the
Zanesville  City  Well  Field.   The  estimated
present worth cost for this remedial  action  is
$2,972,450, which includes a present worth O&M
cost of $1,952,300.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil clean-up goals are based
on  risk-based  levels for a cumulative excess
lifetime cancer risk less than  10"6 and  an HI<1,
and include TCE 6.3 ug/kg and lead 12 mg/kg.
Chemical-specific ground water clean-up goals
are based on SDWA MCLs,  and include TCE
5 ug/1.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to control
future use of the UTA facility until soil clean-up
levels have been met and to control the use and
placement of  wells  in the affected area  until
ground water clean-up levels have been met.

                                  September 6,1991
SITE HISTORY/DESCRIPTION;

The Cimarron Mining site  consists of  two
inactive  ore-processing  mills  in  Carrizozo,
Lincoln County, New Mexico. Operable Unit 2
(OU2), which is the focus of this ROD, addresses
contamination at the 7.5-acre Sierra Blanca mill
location. Land use in the area is predominantly
residential,  with  an  estimated  900  people
residing within 1/2 mile north/northwest of the
site. Onsite features at the Sierra Blanca location
include two buildings,  four discharge pits, one
cinder  block  trench, a  septic tank system, and
numerous process  tanks  and  material  piles.
Prior to 1970, Scott-Tex, Inc., used  the site to
recover a variety of metals from ores transported
to the  site.   In the early 1970's, the mill  was
temporarily  shut down,  and ownership  was
transferred to the town of Carrizozo.  The site
was then leased and used to recover platinum
and silver from ore material. In  1982, after a
possible spill  occurred at the Cimarron  mill,
milling operations were relocated  to the Sierra
Blanca  mill.   During  operations,  the  facility
discharged contaminated  liquids  onsite  and
produced  approximately 570 cubic  yards of
contaminated  material  piles and  other  waste
sludge. In  1990, EPA investigations revealed
43 cubic yards of tank sediment, 182 cubic yards
of material pile soil and rock,  and 345 cubic
yards  of  discharge pit  sediment and  soil
contaminated with high concentrations of metals,
particularly lead at the Sierra Blanca location. A
1990 ROD  addressed  contamination of the
original Cimarron mill, as OU1.   This ROD
addresses  the final  remedial action of the soil
and waste piles at the Sierra Blanca mill location,
as OU2. The primary contaminants of concern
affecting the soil, sediment, debris, and sludge
are metals including arsenic and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for the site includes
excavating and treating onsite 225 cubic yards of
contaminated material piles and tank sediment,
including cinder block trench  sediment which
failed the TCLP test, using cement solidification
and stabilization; excavating and disposing of
345 cubic yards of contaminated surficial soil
and sludge that did not fail  the TCLP test in an
onsite discharge pit along with the  solidified/
stabilized waste; capping the discharge pit with
an  impermeable cover; removing all process
drums,   and   decontaminating  tanks   and
associated piping onsite; filling in the discharge
pits and the cinder block trench with onsite soil
and covering with clean fill; installing additional
ground  water  monitoring  wells; monitoring
ground  water; and implementing institutional
controls  including deed  restrictions, and site
access restrictions including fencing and zoning
ordinances.  The estimated  present worth cost
for this remedial action  is  $79,000,  which
includes a total present  worth O&M cost of
$10,000.

PERFORMANCE STANDARDS OR GOALS:

Chemical- and action-specific soil clean-up goals
for lead are based on the "Interim Guidance on
Establishing  Soil  Lead  Clean-up  Levels at
Superfund Sites," and remediation levels will not
exceed lead 500 mg/kg.

INSTITUTIONAL CONTROLS:

Deed  restrictions  will  be implemented  to
regulate  use  of property,  to  notify potential
buyers  of past   activities, and  to   restrict
permissible uses.

                                 September 6,1991
SITE HISTORY/DESCRIPTION:

The 500-acre Petro-Chemical (Turtle Bayou) site
is in Liberty County, Texas. Current land use in
the area  is divided among cropland, pasture,
range, forest, and small rural communities. The
site overlies two aquifers and is located partially
within the Turtle Bayou floodplain. Since 1929,
the site has been used for cattle grazing, timber
collection,  and  rice farming.   Since  1971,
numerous  undocumented  disposal  activities
occurred  onsite  involving  primarily
petrochemical wastes. Waste oils were dumped
in unlined  pits and also spread onto Frontier
Park Road, an access road through  the site.
These  disposal  activities  have resulted  in
contamination of onsite soil and ground  water.
Waste samples collected during State and EPA
investigations indicated elevated concentrations
of metals, VOCs, and  organics.  A  1987 ROD
addressed operable unit 1 (OU1), and provided
for excavation of highly contaminated soil from
Frontier Park Road; placement  of the highly
contaminated soil in a temporary RCRA vault;
filling excavated areas with  clean  soil; and
resurfacing the entire length of the road.  This
ROD  for OU2  focuses  on  three  areas  of
contamination  at the  site affecting soil and
ground water contamination, known as the main
waste area, the east disposal area, and the Bayou
disposal area.   The primary contaminants of
concern affecting the soil and ground water are
VOCs including benzene  and xylenes;  other
organics including PAHs; and metals including
lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating 302,800 cubic yards of contaminated soil
onsite using in-situ  vapor extraction to remove
VOCs, including injecting air below affected soil
to enhance removal of VOCs below the shallow
water bearing zone;  controlling vertical air
infiltration  using  an  engineered   soil   and
synthetic   liner  cap;   consolidating
lead-contaminated soil in the Main Waste Area,
followed by capping; using  a slurry wall to
control horizontal migration of ground water;
treating extracted vapors from soil and ground
water  using  catalytic  thermal  destruction;
treating  ground   water  using in-situ  vapor
extraction/air stripping, including injecting air at
the base of the shallow water-bearing zone to
remove  VOCs from ground water; monitoring
ground water; and installing structures to control
surface water run-on and run-off. The estimated
present  worth cost for this remedial action is
$26,430,000, which includes a total present worth
O&M cost of $11,466,000.

PERFORMANCE STANDARDS OR GOALS:

Clean-up goals for soil are based on a leaching
model used to determine the remedial levels in
soil  required  to  protect the  ground  water.
Chemical-specific  soil clean-up goals include
benzene 0.35 mg/kg and 10 mg/kg for soil at
depths of greater than 10 feet and less  than
10 feet, respectively (leachate model), and lead
500 mg/kg (interim guidance). Chemical-specific
ground  water clean-up goals include benzene
5 ug/1 (MCL), lead 15 ug/1 (EPA  policy action
level), and xylenes 10,000 ug/1 (health-based).

                                     May 28,1991
SITE HISTORY/DESCRIPTION:

The E.I. DuPont De Nemours (County RD X23)
site is a paint waste disposal site 3.5 miles south
of West Point in Lee County, Iowa. The site is
divided into two subsites,  McCarl and  Baier,
which are three-fourths of a mile apart. Land in
the  area  is  agricultural,  residential,  and
woodlands, and the nearest residence is located
500 feet  from the McCarl  subsite.   The site
overlies two water-bearing units, separated by 75
feet of very  low  permeable clay.  The  Baier
subsite was  used  as the primary disposal site,
and the McCarl subsite, purchased in 1986, was
used when weather did not allow access to the
Baier  site.   From  1949 to  1953, an  estimated
48,000  to  72,000 55-gallon  waste drums were
disposed of at the two sites. Paint waste was
generally  placed   in  trenches and  burned,
resulting in an estimated 4,500  to 7,000 tons of
ash remaining  onsite.  Paint  cans, ash-like
material, and sludge casting were also visible on
the surface  of the site.   In  1983,  an EPA
investigation of the Baier Farm detected levels of
metals and organics in excess of soil background
levels.  In addition, ground water monitoring
wells, installed during 1985  and 1986, detected
metal concentrations  above MCLs.   A 1989
investigation   identified   the   source  of
contamination as  paint disposed of onsite.
Removal from the Baier site was scheduled for
July 1989 by a Unilateral Administrative Order
from EPA to DuPont, but deferred by a February
1990 amendment.  This ROD addresses the soil,
debris, and ground water, as  a final remedy.
The ground water  was determined to be of little
threat and is not further addressed by this ROD.
The primary contaminants of concern affecting
the soil and debris at  both  subsites are  VOCs
including TCE, toluene, and xylenes; and metals
including arsenic, chromium and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for the site includes
stabilizing/solidifying  the contaminated soil at
both subsites, and covering the stabilized mass
with clean soil and vegetation;  removing and
disposing offsite all surface debris not amenable
to solidification at an authorized  RCRA landfill;
monitoring ground water; and  implementing
institutional controls including deed restrictions.
The estimated  present  worth  cost  for  this
remedial action is $1,400,000. There are no O&M
costs associated with this remedial action.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil clean-up goals are based
on  health-based  criteria,  and  include lead
350 ug/kg, selenium 10  ug/kg,  and cadmium
20 ug/kg.

INSTITUTIONAL CONTROLS:

Institutional controls including deed  restrictions
will be implemented onsite.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The  Ellisville Area  site is a former waste oil
disposal  site in Ellisville,  St. Louis  County,
Missouri.  The site consists of the 11.6-acre Bliss
property and four contiguous properties where
hazardous substances  have  been  identified.
Land use in the area is  mixed residential, rural,
and  recreational.   Surface  run-off at  the site
drains to Caulks Creek, a tributary of Bonhomme
Creek,  which enters the Missouri River  about
1 mile   upstream  of   a  City  of  St.  Louis
waterworks intake.  The site does not lie in  a
floodplain, but flooding of Caulks Creek occurs
during periods of heavy rain. During the 1960's
and  1970's, Bliss Waste Oil  Company used the
site  to  transport and dispose of  waste oil
products (some of  which were contaminated
with dioxin), industrial wastes, and chemical
wastes.  Liquid wastes were poured into pits,
applied to the ground surface, and stored in
drums and buried.   Dioxin-contaminated waste
oil was applied directly to surface soil  for dust
control, and spillage from trucks also occurred.
Investigations conducted from 1982 through 1983
concluded  that  site contamination was not
affecting the ground   water; however,  some
onsite surface migration of contaminated soil and
sediment  had occurred.   In 1985, the State
constructed  a  diversion  dike  to  redirect
stormwater run-off, which flowed through a fill
area  containing buried  drums; and fenced the
site.  A 1986 ROD selected  a  final  remedy for
non-dioxin wastes  at the site and an interim
remedy for dioxin  waste at the site including
excavation  and interim  onsite   storage of
dioxin-contaminated materials.   The  interim
remedy has not been implemented.  A1988 ROD
for the Times Beach site established the
availability of a  thermal treatment unit at the
Times Beach site to treat dioxin-contaminated
sites in eastern Missouri including the Ellisville
Area.  This ROD provides a final  remedy for
dioxin-contaminated   soil,   which  involves
excavation and direct transport of dioxin wastes
offsite  for  treatment.   The  1986  remedy for
non-dioxin wastes is not affected. The primary
contaminant  of  concern  affecting  the  soil is
dioxin, an organic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating   and   direct  transportation   of
approximately   7,000  cubic   yards   of
dioxin-contaminated soil  for treatment at  an
offsite   temporary  thermal   treatment  unit
constructed at the Times Beach site; disposing of
treatment residuals at the Times Beach site as
nonhazardous solid waste if delisting criteria are
met, or retreating at Times Beach or managing
residuals offsite as a hazardous waste if delisting
criteria are not  met.   The estimated  present
worth cost for this remedial action is $17,530,000.
There are no O&M costs associated with this
remedial action.

PERFORMANCE STANDARDS OR GOALS:

Performance standards for the thermal treatment
of soil  include  six-nines  (99.9999  percent)
destruction and removal efficiency and delisting
of the thermal treatment residue.

SITE HISTORY/DESCRIPTION:

The Ellisville Area  site  is a former waste oil
disposal  site in Ellisville,  St. Louis County,
Missouri.  The site consists of the 11.6-acre Bliss
property and four contiguous properties where
hazardous  substances  have  been identified.
Land use in the area is mixed residential, rural,
and recreational.   Surface  run-off at the site
drains to Caulks Creek, a tributary of Bonhomme
Creek,  which enters the Missouri  River about
1 mile   upstream  of  a city   of St.  Louis
waterworks intake.  The site does not lie in a
floodplain, but flooding of Caulks Creek occurs
during periods of heavy rain. During the 1960's
and 1970's, Bliss Waste Oil  Company used the
site  to  transport and  dispose of waste  oil
products (some of  which were contaminated
with dioxin), industrial  wastes, and  chemical
wastes.  Liquid wastes  were poured into pits,
applied to  the ground  surface, and stored in
drums and buried.   Dioxin-contaminated waste
oil was applied directly to surface  soil for dust
control, and spillage from trucks also occurred.
Investigations conducted from 1982 through 1983
concluded  that  site contamination was not
affecting the ground  water; however,  some
onsite surface migration of contaminated soil and
sediment had occurred.   In 1985,  the State
constructed  a  diversion  dike  to  redirect
stormwater run-off, which flowed through a fill
area containing buried drums;  and fenced the
site. A 1986 ROD  selected  a final remedy for
non-dioxin  wastes  at the site and an interim
remedy for dioxin  waste at the site including
excavation   and  interim  onsite  storage  of
dioxin-contaminated materials.   The interim
remedy has not been implemented.  A 1988 ROD
For  the  Times  Beach  site  established  the
availability of a thermal treatment unit at the
Times Beach  site  to treat dioxin-contaminated
sites in eastern Missouri including the Ellisville
area.  This ROD amends the 1986 ROD because
the pending availability of a thermal treatment
unit at Times Beach  has prompted EPA  to
reconsider the need for excavation and interim
onsite storage. This ROD also provides a final
remedy for  dioxin-contaminated  soil,  which
involves  excavation and direct transport  of
dioxin wastes offsite for treatment.  The 1986
remedy for non-dioxin wastes is not affected.
The primary  contaminant of concern affecting
the soil is dioxin, an organic.

SELECTED REMEDIAL ACTION:

The amended remedial  action  for this  site
includes excavating, and direct transportation of
approximately   7,000  cubic  yards    of
dioxin-contaminated soil  for treatment at  an
offsite  temporary  thermal   treatment  unit
constructed at the Times Beach site; disposing of
treatment residuals at  the Times Beach site  as
nonhazardous solid waste, if delisting criteria are
met, or retreating  at Times Beach or  managing
residuals offsite as a hazardous waste if delisting
criteria are not met. No costs were provided for
this amended  remedial action.

Performance standards for the thermal treatment
of  soil include   six-nines  (99.9999  percent)
destruction and removal efficiency and delisting
of the thermal treatment residue.

                                 September 30,1991
 SITE HISTORY/DESCRIPTION:

 The Hastings Groundwater Contamination site
 consists of localized areas where the aquifer is
 contaminated   with   industrial   chemicals,
 primarily VOCs, in the City of Hastings, Adams
 County, Nebraska. This ROD addresses part of
 the Colorado Avenue subsite, which is one of
 several  Hasting Groundwater Contamination
 subsites.  This subsite consists of contaminated
 soil  at three industrial properties, which was
 addressed in a 1988 ROD as OU9, and a ground
 water contaminant plume approximately 1 mile
 long, which is the subject of this ROD and
 referred to as  OU1.  Land use in the area is
 residential and industrial.  The West Fork Big
 River lies to the north of the site, and the site is
 characterized by a nearly  flat ground  surface
 with  a  gentle  slope to the southeast.  The
 estimated 23,000 residents of Hastings obtain
 their drinking  water from a  municipal system
 that taps into the underlying sole-source aquifer.
 From 1967  to  1982, Dravo  Corporation,  the
 former owner of one of the industrial properties,
 manufactured  heating  and  air  conditioning
 equipment  onsite and  discharged chlorinated
 solvents from its vapor degreasing process into
 sanitary and storm sewers. Leaky sewer joints
 and discharge  of storm drains to open ditches
 have  resulted in  seepage  of  chlorinated
 compounds into the soil, and eventually into the
 aquifer.   In 1983, after 30 years of nonuse,
 Hastings municipal well #18 was put back online
 to pump ground  water, but complaints from
citizens about the odor  and taste of the water
 prompted the  city to remove the  well from
service. In 1985, EPA investigated onsite ground
water contamination, including well #18, and
identified   onsite  TCA,  TCE,   and  PCE
contamination.   Monitoring wells  showed that
the contaminant plume  extended about 1 mile
eastward  in the direction of ground water flow.
The source of this contamination was traced to
Dravo's industrial facility.  All affected wells
 were subsequently shut down.  A 1988 ROD
 addressed the soil component of the Colorado
 Avenue subsite as OU9 and identified treatment
 using  soil  vapor  and   vacuum   extraction
 technologies, followed by treatment of extracted
 vapor  using an activated carbon system, and
 monitoring soil, ground water, and  air.  This
 ROD addresses the ground water contamination
 component as OU1.  Future RODs may address
 additional source control measures, subsurface
 monitoring,  ground  water  extraction   and
 treatment, wellhead protection and treatment,
 and provide institutional controls. The primary
 contaminants of concern affecting  the ground
 water are VOCs including DCE, PCE, and TCE.

 SELECTED REMEDIAL ACTION:

 The  selected remedial action  for this interim
 remedy includes managing  the contaminant
 plume by pumping a number of pore volumes
 (5,550,000 gallons) of VOC-contaminated ground
 water, treating the extracted ground water onsite
 using  granular  activated  carbon  (with  a
 contingency to use air stripping and emissions
 treatment, or UV oxidation),  and reusing or
 reinjecting  the   treated  ground   water;
 regenerating spent carbon offsite; and monitoring
 ground water quality to measure effectiveness of
 the interim action. The estimated present worth
 cost for this remedial action is $6,061,000, which
 includes an  annual  O&M  cost  ranging  from
$269,000 to $767,000 for 10 years.   EPA has
increased   the  estimated   remedial  action
 timeframe for this interim  action to  15 years.
The total present worth cost of the remedial
action will increase from the 10-year estimate
primarily due to a longer period of O&M.

PERFORMANCE STANDARDS  OR GOALS:

Chemical-specific ground water clean-up goals
are based  on  State  and Federal MCLs, and
include PCE 0.005 mg/1 and TCE 0.005 mg/1.

                                 September 30,1991
 SITE HISTORY/DESCRIPTION:

 The Hastings Groundwater Contamination site
 consists of localized areas where an aquifer is
 contaminated with industrial  chemicals in or
 near the  City  of  Hastings, Adams  County,
 Nebraska. Both the source control operable unit
 10  (OU10) and ground water operable unit
 (OU2) of the North Landfill, a 13.4-acre former
 municipal landfill are addressed by this ROD.
 Land use  near the landfill is mixed residential
 and commercial with an active railroad directly
 north of the site. The estimated 23,000 residents
 of Hastings obtain their drinking water from the
 municipal water system, which taps into the
 underlying sole-source aquifer. As early as 1938,
 brickmakers obtained clay source materials from
 the area of the landfill.  From 1961  to 1964, the
 City of Hastings operated a municipal landfill
 onsite and accepted municipal and industrial
 wastes including wastes containing  VOCs. The
 landfill was initially capped, and  later in the
 1970's an additional 2 feet of capping materials
 were  added.     In  1983,   ground   water
 contamination was  discovered when the  Stale
 sampled  the  Hastings  public  water supply
 system in  response  to citizen  complaints about
 water  quality.     EPA  investigations   have
identified VOCs including benzene, TCE, DCE,
and vinyl chloride in the ground water adjacent
to and downgradient from the site.  In 1985,
soil-gas samples indicated that the vadose zone
above the aquifer was contaminated. This ROD
provides  an interim remedy for  both  OUs.
Future  RODs may address  additional  source
control measures, subsurface monitoring, ground
water extraction and treatment, wellhead
protection  and treatment,  and provision  of
institutional controls. The primary contaminants
of concern  affecting the soil and ground water
are VOCs  including  TCE, DCE, and vinyl
chloride.

SELECTED REMEDIAL ACTION:

The selected remedial action for this  interim
remedy includes  geotechnical  testing  of  the
existing landfill cap, improving the present cap
through regrading to promote surface run-off,
and revegetating the landfill surface;  pumping
and onsite  treatment of contaminated ground
water with  a technology to be determined after
further testing, but will be either air stripping or
UV oxidation; monitoring  the  vadose zone,
saturated  zones,  and ground  water;  and
implementing  institutional controls including
deed restrictions, and site access restrictions such
as fencing. The estimated present worth cost for
this remedial action will range from $2,300,000 to
$4,000,000, based on ground water treatment and
discharge options.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water  clean-up goals
are based on SDWA MCLs, and include
TCE 5 ug/1, cis 2-DCE 70 ug/1, trans 1,2-DCE
100 ug/1, and vinyl chloride 2 ug/1.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented onsite to
prevent construction, and ensure cap integrity.

                                 September 23,1991
SITE HISTORY/DESCRIPTION:

The 105-acre  John  Deere (Ottumwa  Works
Landfill) site is an active agricultural equipment
manufacturing   and   assembly  facility   in
Ottumwa, Wapello County, Iowa.  Land use in
the  area  is  predominantly residential, with
wetlands located within 1,000  feet of the site
across the Des Moines River. All of the site lies
within the 100-year floodplain of the Des Moines
River, and a drainage ditch borders the site on
the east side.  The estimated 27,000 Ottumwa
residents use municipal water obtained from the
Des Moines  River as their drinking water
supply.    The  municipal  intake  is  located
approximately 1,000 feet upgradient from the
site. Black Lake, located 150 feet east of the site,
is  used  as an additional  water source  on an
infrequent basis, contributing approximately 1/2
to 1-1/2 percent of the  total annual volume  of
water distributed by the Ottumwa Water Works.
From 1911  to 1973, Deere  & Company buried
plant-generated wastes including solvents, paint
sludge,  heat  treating cyanide, heat treating
sludge, petroleum distillates, and foundry sand
in the  shallow alluvium  underlying the site.
After landfilling,  some of  the wastes  were
burned onsite on a regular basis. In 1965, Deere
& Company acquired the southwestern portion
of the site, which had been used previously as a
salvage yard.  In the late 1980's, investigations of
the disposal areas identified subsurface soil and
ground  water contamination by VOCs, other
organics, and  metals. This ROD addresses the
disposal areas, the drainage ditch, and Black
Lake surface water. The primary contaminants
of concern affecting the soil, sediment, debris,
and ground water are organics including PAHs;
and  metals including arsenic, chromium, and
lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
implementing  institutional  controls  including
deed  restrictions, and  site  access restrictions
including maintaining the perimeter fence.  The
estimated present worth cost for  this remedial
action  is $4,000.   There are no O&M costs
associated with this remedial action since fence
maintenance is covered by the facility's operating
budget.

                                  December 31,1990
 SITE HISTORY/DESCRIPTION:

 The 6-acre Kem-Pest Laboratories site is a former
 pesticide production  facility  located  in Cape
 Girardeau  County,  Missouri.   Site  features
 include a concrete block building that housed the
 pesticide formulation operation and  currently
 holds  approximately   11,200   gallons   of
 contaminated water in its basement; six storage
 tanks used for storing solvents and oil; and a
 lagoon used for the disposal of sewage and plant
 waste. An unconfined aquifer system lies within
 the alluvial and colluvial  deposits at the site.
 From  1965 to  1977, Kem-Pest  Laboratories
 formulated various pesticide products including
 liquid pesticides,  granular   insecticides  and
 herbicides,  and pesticide dust onsite.  Wastes
 generated from pesticide production contained
 several  pesticides  including  aldrin,  dieldrin,
 endrin,  and heptachlor.   Plant wastes were
 disposed of in the onsite lagoon.  No production
 or disposal activities have occurred onsite since
 1977, and the lagoon was backfilled with clay by
 the  owner in  1981.    Based  on   Federal
 assessments and  investigations conducted  in
 1981, it was determined that the lagoon and the
 formulation building were the most significant
 sources of  site contamination.  Ground water
 contamination  has occurred from the migration
 of contaminants from the soil within the lagoon;
 ground  water  may  also  act as  a  flushing
 mechanism for contaminants in the subsurface
 soil.   A  1989 ROD  addressed  OU1,  the
 contaminated surface soil in the lagoon; surface
 soil in the lagoon area and near the formulation
building; and  sediment  in drainage  channels
onsite and offsite. This ROD addresses  pesticide
contamination  in  the formulation building,
ground water, and  surface water, as OU2.  The
primary contaminants of concern affecting debris
and surface water are VOCs including  benzene;
other organics  including  pesticides;  and metals
including arsenic, chromium, and lead.
 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 decontaminating the formulation building by
 surface   layer  removal;   dismantling
 approximately 50 tons of interior structures and
 formulation  equipment   not  amenable  to
 decontamination, followed by offsite incineration
 and disposal of decontaminated and dismantled
 debris; implementing additional decontamination
 measures including scarification and applying a
 sealant  to  the concrete  floors,  if  necessary;
 collecting and  treating onsite  approximately
 11,200 gallons of water that has collected in the
 basement of  the formulation  building using
 activated   carbon  adsorption,   with  onsite
 discharge of  the  water  and offsite carbon
 regeneration or disposal; long-term ground water
 and surface  monitoring;  and  implementing
 institutional controls.   The estimated present
 worth cost  for this remedial action is $727,000,
 which includes an annual O&M cost of $5,000
 for 30 years.

 PERFORMANCE STANDARDS OR GOALS:

 No Federal or State clean-up standards exist for
 remediation of contaminated structures in regard
 to  risks  posed by direct  contact.  EPA has
 determined that a 10"5 individual lifetime excess
 cancer risk  will be protective of human health
 from   risks  associated  with  contaminated
 structures. Performance standards for inhalation
 of pesticides are the worker permissible exposure
 limits as defined by OSHA regulations including
 aldrin 0.25 mg/m3 and dieldrin 0.25 mg/m3.

 INSTITUTIONAL CONTROLS:

 Institutional controls  will be  implemented to
 limit future use of the formulation building to
commercial or industrial activities.

 SITE HISTORY/DESCRIPTION:

 The 2.5-acre Lee Chemical site is a former water
 treatment plant and  chemical  repacking and
 distributing facility in Liberty, Clay  County,
 Missouri. Land use in the area is commercial
 and rural.   The estimated  17,000 people who
 reside in Liberty obtain  drinking  water from
 municipal water  wells located approximately
 2,000 feet southeast of the site.  These wells draw
 water from  the alluvial aquifer underlying the
 site. From 1920 to 1962, the city of Liberty used
 the site as the city's water treatment plant. From
 1965 until 1975, when the city repossessed the
 property, the site was leased  to Lee Chemical
 Company  for   packaging and   distributing
 commercial and industrial cleaning solvents and
 other chemicals, some of which were reprocessed
 onsite in 55-gallon drums.  In  1977, as required
 by  EPA, the city removed and  disposed  of
 approximately three hundred 55-gallon drums of
 waste offsite. In 1979, low levels of TCE were
 detected in the  public water supply wells.
 Subsequent  EPA   and   State  investigations
 revealed contaminated ground water, soil, and
 deteriorated drums and chemical containers; and
 in 1982 the city and State identified the site as a
 source of TCE contamination in the public water
 supply.  In 1983, the onsite water plant building
 and its contents were demolished and disposed
 of offsite. In 1984,  in an effort to  contain  the
 contaminated ground water plume  and  reduce
 TCE  levels  in  the  water supply, the  city
 discharged   water  from   the  most   highly
 contaminated of  its  municipal water  wells
 through  an  abandoned  sewer line  to  the
Missouri River and Shoal Creek. Later that year,
an abandoned municipal well onsite was added
 to the plume control measure and the discharge
was diverted to an  abandoned  water main  to
nearby  Town  Branch Creek.    Currently,  no
detectable levels of TCE are found in wells
 connected to the water supply system.   This
 ROD  addresses  soil  and   ground   water
 contamination, and provides a final remedy for
 the site.  The primary contaminants of concern
 affecting the soil and  ground water are VOCs
 including TCE.

 SELECTED  REMEDIAL ACTION;

 The selected remedial action for this site includes
 installing an in-situ aqueous soil washing system
 consisting of infiltration trenches to enhance the
 flushing of contaminants from onsite soil to the
 underlying aquifer; pumping ground water to
 flush contaminants from the underlying aquifer
 to the extraction system and to control ground
 water movement away from the site, followed by
 onsite discharge to surface water; implementing
 a contingency phase  ground  water treatment
 project consisting  of  air  stripping  or  other
 treatment methods, if additional treatment  of
 discharge water becomes  necessary to  meet
 health based risk levels, existing NPDES permit
 limits, or other ARARs; and monitoring ground
 water and air. The estimated present worth cost
 for  this  remedial  action  is  $550,000,  which
 includes  an  annual O&M cost of $52,000 for 5
 years.  If treatment is deemed necessary,  the
 revised present  worth cost for this  remedial
 action is  $670,000, which  includes an annual
 O&M cost of $67,000 for 5 years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific goals for  soil  were  not
provided.   Chemical-specific  ground  water
clean-up goals are based on SDWA MCLs and

                                     June 28,  1991
 SITE HISTORY/DESCRIPTION:

 The Lehigh Portland Cement site is composed of
 two areas: the 150-acre Lehigh Portland Cement
 Company (LPCC)  cement production facility,
 and the 410-acre Lime Creek Nature Center
 (LCNC), in Mason, Gordo County, Iowa.  Land
 use in  the  area  is  rural,  agricultural,  and
 industrial.   The site overlies an aquifer that
 serves as a source of water for 12  nearby wells;
 and municipal water is obtained from a deeper
 aquifer.  Calmus Creek borders  the site and
 discharges  to the  Winnebago River, located
 within a mile of the  site.  From 1911 to the
 present,  the LPCC  has manufactured cement
 products. As a result of operations, site features
 currently include four abandoned quarries at the
 LPCC area, which were worked until the 1950's,
 and subsequently were filled in with water, and
 numerous tailings piles. The water bodies are
 known as Blue Waters Pond, Arch Pond, Cooling
 Waters  Pond, and  Area C Pond.  During its
 history, the LPCC disposed of cement kiln dust
 (CKD) in several onsite piles and in Area C
 Pond.  The LCNC  area was used by LPCC to
 quarry materials until 1979, and  subsequently
 was backfilled with CKD from the parent site
 and sold. Consequently, the LCNC quarries also
 have become ponds, including Quarry Pond. In
 1981, hydrochemical tests of Blue  Waters Pond
 on  the  LPCC area indicated high alkalinity.
 Subsequent  investigations  indicated  that the
 ponds on the LCNC area  also have high pH
 levels, although water quality is better than at
 the LPCC area.  Testing showed that CKD was
 the  cause  of  high  alkalinity,  and  that
contamination of the aquifers has  occurred.  In
addition, a flow control structure installed on the
southeastern corner of Blue Waters Pond allowed
highly alkaline water to discharge into Calmus
Creek.   Subsequently,  overflow prevention
measures at Blue Waters Pond were
implemented by LPCC, but seepage to Calmus
Creek continued. This ROD addresses the CKD,
ground water,  and surface  water  as a final
remedy.   Elevated pH of ground  water  and
surface water also is of potential concern.

SELECTED REMEDIAL ACTION:

The selected remedial action for the LPCC area
includes dewatering Blue  Waters, Area C,  and
Arch Ponds, and treating pond water using acid
neutralization,  followed by  ion  exchange or
reverse osmosis if needed, with onsite discharge;
excavating and consolidating  CKD  from Blue
Waters and  Arch  Ponds within Area  C Pond,
followed by constructing a clay cap over Area C
Pond; constructing a cap over the existing area
known as the CKD Reclamation Area; collecting
shallow ground water via sumps and a seep
collection system constructed in the base of Blue
Waters and  Area C  Ponds,  and treating  the
ground water  in  the onsite  treatment system
before  onsite  discharge;  monitoring  ground
water, surface water, and treated discharge; and
implementing  institutional controls including
deed restrictions.  The selected remedial action
for the LCNC area includes constructing  a dam
across  Quarry  Pond and draining the western
portion of the pond; excavating CKD within the
western  portion   of  Quarry  Pond  and
consolidating the  CKD within an  exhausted
quarry east of the pond; constructing a  clay cap
over the exhausted quarry; consolidating CKD
from all other LCNC areas in the Badlands area,
and constructing a clay cap over the consolidated
material; allowing Quarry Pond to  refill; and
monitoring  ground water  and surface  water.
The estimated present worth  cost for remedial
action at the LPCC area is $3,400,000, and for the
LCNC area is $1,600,000.  No O&M  costs were
provided for the remedial action.

                                 September 24,1991
SITE HISTORY/DESCRIPTION:

The 98.7-acre Mid-America Tanning site is a
former  leather  tannery  in  Sergeant  Bluff,
Wood bury County, Iowa. Surrounding land use
is mixed industrial and agricultural. A portion
of the site is bordered by Oxbow Lake and lies
within the 100-year  floodplain.  The Missouri
River is approximately 1.5 miles to the southwest
of the site and receives discharges from Oxbow
Lake.   The facility began onsite processing of
animal hides in 1970. From 1973 to 1989, the site
was used intermittently under various owners as
a chrome tanning operation. Process wastewater
containing   debris,  chromium,   and  other
chemicals was discharged to onsite lagoons and
impoundments.    Sludge  generated from the
process was disposed onsite in the surficial soil
or in   disposal  trenches.   Occasional system
overloads  resulted in  overflow of chromium
wastewater into Oxbow Lake. In 1980, the State
confirmed   the  onsite   burial   of
chromium-containing sludge in trenches, and the
company was cited for permit violations. A1985
EPA investigation identified excessive chromium
contamination in onsite  soil,  sediment, and
ground water.   In  1990, EPA conducted  a
removal action  that included excavating and
consolidating onsite 1,290 cubic yards of sludge
from  the  trench  disposal area.   This  ROD
addresses the contaminated soil, impoundment
sediment and water, and the excavated trench
material.  A  future  ROD will  address onsite
ground water contamination.   The  primary
contaminants of  concern  affecting  the  soil,
sediment, debris, sludge, and surface water are
metals including chromium and lead.
SELECTED REMEDIAL ACTION:

The selected remedial action for the site includes
treating 8,300 cubic yards of contaminated soil
and  44,500   cubic  yards  of  impoundment
sediment onsite using  in-situ immobilization;
immobilizing  1,293 cubic yards of consolidated
trench sludge onsite, followed by either onsite or
offsite  disposal;  removing and disposing of
debris  offsite and discharging impoundment
water  onsite  through  an  NPDES-permitted
outfall  or treatment, if needed,  with offsite
discharge to  a POTW;  capping contaminated
areas,  and grading  and seeding  top  soil;
conducting  ground   water  monitoring;   and
implementing institutional controls  including
deed restrictions.  A contingent remedy using
ex-situ  immobilization will be implemented if
treatability studies determine that the selected
remedy is inadequate.  The estimated present
worth cost for this remedial action is $4,857,000,
which includes an annual O&M cost of $21,000.

PERFORMANCE STANDARDS OR GOALS:

Federal  and  State  clean-up  standards  for
chromium have not been established at this time.
Clean-up objectives are  based on a Iff4 cancer
risk to  human health and include hexavalent
chromium 2,490 mg/kg.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented at the site
to ensure that it is not  used for residential or
agricultural purposes, and that buildings are not
constructed on the capped areas.

                                 September 16,1991
 SITE HISTORY/DESCRIPTION:

 The 5-acre People's Natural Gas site is a former
 coal gasification plant in Dubuque County, Iowa.
 The City of Dubuque maintains a public works
 garage on the eastern portion of the site, and the
 Iowa Department of Transportation owns the
 western portion. The site is located 300 feet west
 of  the  Mississippi  River, and is  within  the
 Mississippi River  floodplain.  In addition, the
 site overlies a silty sand unit  and  an alluvial
 aquifer, which  has been determined to be a
 potential source of drinking water. Surrounding
 land use is primarily industrial and commercial,
 with adjacent residential areas. From at least the
 1930's to 1954, the site was used to manufacture
 gas. By-products produced during this process
 included coal tar,  which was stored  in an
 underground tank and an above-ground tank,
 and cyanide-bearing woodchips, which were
 buried on the eastern portion of the site.  From
 1954 to 1964, the site was used  as a natural gas
 distribution, storage, and maintenance facility.
 In 1986, EPA investigations identified extensive
 contamination of onsite soil and  ground water at
 the site. In 1989, the PRPs conducted a removal
 action that included excavating 5,500 cubic yards
 of  PAH-contaminated soil  from the western
 portion of the site, removing tanks used to store
 coal tar, installing a leachate collection system to
 prevent contamination from  leaching into  the
 alluvial aquifer; and implementing institutional
 controls.  This  ROD addresses both  soil and
 ground water contamination, as a final remedy.
 The primary contaminants of concern  affecting
 the soil and  ground water are VOCs including
benzene, toluene,  and   xylenes; and   other
 organics including PAHs.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and incinerating an estimated 18,500
cubic yards of contaminated soil offsite; treating
the soil and ground water within the silty sand
unit, which  are contaminated  with coal  tar
wastes using in-situ bioremediation; pumping
and onsite treatment of contaminated ground
water using air stripping, followed by offsite and
storm sewers discharge to a POTW; monitoring
ground  water  and air;  and  implementing
institutional controls such as ground water and
land use restrictions,  as  well as  site  access
restrictions including fencing.  A contingency for
ground  water treatment includes  engineering
controls and an ARAR waiver if the extraction
system does not achieve clean-up  levels.  The
estimated present worth cost for this remedial
action is $8,000,000, which includes an estimated
O&M cost of $788,000 for 10 years.

PERFORMANCE STANDARDS OR GOALS:

Federal  and  State  clean-up standards for soil
have  not  been   established  at   this   time.
Therefore, goals for soil cleanup are based on a
carcinogenic  risk  level  of 10 , and include
500 mg/kg  for  total PAHs  and carcinogenic
PAHs 100 mg/kg.   Remediation   levels  for
ground water are based on SDWA  MCLs, and
include benzene at  1 ug/1.

INSTITUTIONAL CONTROLS:

Ground  water and  land use restrictions will be
implemented  onsite to prevent  direct contact
with contaminants.

                                 September 26,1991
SITE HISTORY/DESCRIPTION:

The 26-acre  Shaw  Avenue Dump site  is a
chemical  waste  site  in  Charles  City, Floyd
County,  Iowa.   Land  use  in  the  area  is
predominantly residential. Part of the site lies
within the 100-year floodplain of the Cedar
River,  and  a   wetlands  area   is  located
approximately 600 feet south of the site.  From
1899  to 1964, Charles City  used the  site  as a
municipal landfill for waste incineration, and
disposal of liming sludge from the city's POTW.
Asphaltic materials continue to be disposed of in
the onsite landfill.  Additionally, from 1949 to
1953, chemical  wastes generated  by  chemical
batch processing of arsenic and compounds used
in the production of animal pharmaceuticals at
Salsbury Laboratories  were  disposed of onsite.
Between 1977 and 1981, the State issued reports
based on studies of the site and surface water
that documented elevated levels of metals in an
abandoned   gravel   pit  near   the   site.
Approximately  14,000 to 28,000 cubic feet of
chemical waste and 10,000 tons of solid waste
from  the  POTW  including sludge containing
hazardous waste from Salsbury Laboratories, and
associated  contaminated  soil  are  currently
present  onsite.   Leaching of contaminants,
especially  arsenic,  from  370  cubic yards of
chemical fill and adjacent soil into ground water
is thought to be the principal threat at the site.
A 200-gallon underground storage tank (UST) is
located within the vicinity of  the chemical fill,
and also is considered to be a possible source of
onsite contamination.  This ROD addresses the
chemical fill, surrounding contaminated soil, and
the underground gasoline tank as operable unit
1  (OU1).     A   future  ROD  will   address
contaminated ground  water  as  OU2.   The
primary contaminants of concern affecting the
soil and debris are VOCs including benzene,
toluene, and xylenes; other organics including
PAHs; metals including arsenic and lead; and
other inorganics.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating the chemical fill and soil using in-situ
fixation   and   stabilization,   followed   by
constructing a low  permeability cap over  the
fixed  and stabilized fill; conducting treatability
studies  to determine the effectiveness  of  the
treatment, and  if  treatment  is not  effective,
issuing  an ESD and disposing of  the waste
offsite; removing and  disposing of offsite  the
underground gasoline tank; monitoring ground
water quality; and  implementing  institutional
controls including  deed restrictions, and site
access restrictions  including  fencing.    The
estimated present worth cost for this remedial
action is $513,400, which  includes an annual
present worth O&M cost of $65,550.

PERFORMANCE STANDARDS OR GOALS:

Action-specific soil clean-up goals are based on
State  and  Federal standards, RCRA  Land
Disposal  Restrictions,  OSHA,  RCRA  Toxic
Characteristic Leachate  Procedure,  and UST
regulations, and include arsenic 50 mg/kg and
cadmium 20 mg/kg.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prevent
construction, installation,  and maintenance of
any ground water wells. Access easements also
will be implemented to prevent unauthorized
entry  to the site.

 potential sources of drinking water. From 1884
 until  1980 when activities ceased,  the site  was
 used for ore processing and smelting operations.
 Rue  dust was  generated  as a by-product of
 copper smelting operations. The majority of flue
 dust that was generated was reprocessed,  and
 the remaining portion was stockpiled  at nine
 locations on and around the site.  In 1988, EPA
 conducted  an investigation to determine the
 nature and extent of the flue dust contamination.
 A 1988 ROD addressed the Mill Creek operable
 unit (OU15) and documented the relocation of
 residents from the community surrounding the
 smelter site as the selected remedial action. This
 ROD  addresses the Flue Dust Operable Unit
 (OU11). Subsequent RODs will address further
 site contamination in adjacent soil, ground water,
 and surface water. The primary contaminants of
 concern affecting  this site  from the  flue dust
 materials are metals including arsenic, cadmium,
 and lead.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating a total of approximately 316,500 cubic
yards of flue  dust  from the nine flue dust
locations and  treating  the dust  onsite using
cement/silicate based stabilization; disposing of
the treated residuals in an onsite engineered
repository, which will include a soil or clay liner
and a leachate collection system; conducting air
and ground water monitoring; and implementing
institutional  controls  including   land   use
restrictions, and site access restrictions.   The
estimated capital cost for this remedial action is
$25338,000, with an annual O&M cost of $10,000.

PERFORMANCE STANDARDS OR COALS:

The treatment levels of flue dust cement/silicate
based  stabilization  will render the  material
non-hazardous   by   meeting  RCRA  TCLP
regulatory limits, and include levels that  will
limit leaching of contaminants to ground water
to arsenic 5 mg/1, cadmium 1 mg/1, and lead
5 mg/1.

INSTITUTIONAL CONTROLS:

Land use restrictions will be implemented.

                                 September 24,1991
 SITE HISTORY/DESCRIPTION:

 The 64-acre Broderick Wood Products (BWP) site
 is a former wood treatment facility in Adams
 County,  Colorado.   Land use in the area  is
 predominantly industrial.  The site is one-half
 mile south of Clear Creek, a perennial stream.
 The nearest residences are less than one-eighth
 mile north of the site.  From 1947 to 1981, BWP
 used  the  site for treating power poles,  fence
 posts, railroad ties,  and other wood products.
 Process wastes  from the onsite plant  were
 disposed  onsite   in   two  unlined   surface
 impoundments in the northwest  corner of the
 site. Waste seepage occurred just north of the
 site and was burned off starting in 1955.  Also,
 four other ponds were periodically used for this
 purpose, and several fires have occurred onsite.
 In 1981,  BWP submitted a RCRA permitting
 application  and  obtained  interim status  to
 operate its facility, but ceased operations because
 of economic conditions.  As a result of the waste
 disposal  practices   at  BWP, a  number  of
 investigations were conducted by EPA and the
 State.   In 1981  and  1982, EPA  noted several
 violations of RCRA requirements; and other site
 investigations identified possible contamination
 of a trench near the surface impoundments that
 had reportedly been used for the disposal of
 solid waste, and ground  water contamination
 downgradient of the  surface impoundments.
 Additionally, a  fire in  1985  damaged  the
 treatment plant building.  Water that was  used
 to fight the fire  has been contaminated  with
 asbestos and remains in  the basement of the
building. A 1988 ROD addressed interim source
control treatment of onsite sludge, as operable
unit 1 (OU1), and provided for excavation and
onsite  incineration  of  impoundment   sludge,
onsite  incineration  or  stockpiling  of  visibly
contaminated soil found beneath the sludge, and
treatment of water in the impoundments and
 buildings. Based on new technical data and cost
 information EPA has  decided  against using
 incineration as treatment in OU1.  This ROD
 amends the original 1988 remedy for sludge
 treatment.  A future ROD will address the final
 remedy for the site by providing for treatment of
 contaminated  soil,  debris, and  surface  and
 ground  water, as  OU2.    The  primary
 contaminants of concern affecting the sludge are
 VOCs including toluene  and xylenes; other
 organics including dioxin and PAHs; and metals
 including lead.

 SELECTED REMEDIAL ACTION:

 The amended  remedial  action for this  site
 includes  excavating and  preparing 950 cubic
 yards of solid sludge, 1,220 cubic yards of liquid
 sludge, and 500 gallons of oil collected from the
 sludge from temporary storage cells within the
 impoundments  area; and  transporting sludge
 and oil to  a  permitted  recycling facility to
 reclaim creosote for  use at other wood treating
 facilities,  followed  by  offsite incineration of
 recycler  residues,   and  offsite  disposal  of
 incinerator  ash in a permitted landfill.   The
 estimated  total cost  for  this  remedial action
 ranges from $2,058,200 to $2,191,000. O&M costs
 are  included  in  the  capital  costs  because
 treatment will occur offsite.

 PERFORMANCE STANDARDS OR GOALS:

 Chemical-specific sludge  clean-up  goals  are
based on RCRA land disposal restrictions and
 include lead 0.51 mg/1, toluene 28 mg/kg, and
 xylenes 33 mg/kg.

                       CENTRAL CITY-CLEAR CREEK, CO
                                 September 30,1991
 SITE HISTORY/DESCRIPTION:

 The Central City-Clear Creek site is an active
 mining facility in Central City, Clear Creek and
 Gilpin counties, Colorado.  Land use in the area
 is predominantly commercial and recreational,
 and an artificial wetlands area is located onsite.
 The site lies within the 400-square mile drainage
 basin of Clear Creek, which serves as a drinking
 water  source for several municipalities.  Gold
 mining operations began  onsite in 1859 and
 portions of the site became  some of the most
 heavily mined areas of Colorado. Extraction of
 surface ores led  to an increase  in the depth of
 the mining and, consequently, drainage tunnels
 were  constructed to  control water  drainage
 problems.  Presently, six major mine drainage
 tunnels are thought to be principal discharge
 sources of acid  mine  water containing high
 concentrations of  metals  to  surface waters
 including Clear  Creek  and its tributaries.   In
 addition, over 21 mine tailings piles with an
 estimated total volume of  over 2,000,000 cubic
 yards at numerous locations throughout the site
 are   thought   to  be   major  sources   of
 contamination.     In   response   to   site
 contamination, EPA has conducted three removal
 actions since 1987.  In 1987, EPA conducted a
 removal action to prevent the collapse of a mine
 waste  pile.  Also in  1987, EPA conducted a
 second   removal   action,   which   involved
 connecting three residences with private wells to
 the municipal public water supply. In 1991, EPA
 conducted  a  third  removal  action,  which
 involved removing uncontaminated  mercury
 from a small trailer.  Because of the complexity
of the site, EPA divided the site into several
operable units (OUs) for remediation.  A 1987
ROD addressed OU1 and provided  for passive
treatment of acid mine water discharge from five
discharging tunnels: National, Gregory Incline,
 Argo Tunnel, Big Five, and Quartz Hill tunnels.
A 1988 ROD addressed OU2 and provided for
the remediation of mine waste piles  in  the
immediate proximity  of  the  five discharging
tunnels.   This ROD  supersedes  the  remedy
provided for OU1 in the 1987 ROD by including
active  treatment of  the Argo Tunnel  and
delaying a decision on treating the  discharges
from  the  Big Five, National  and Quartz Hill
tunnels, and the Gregory Incline.   EPA will
consider a subsequent ROD to address treatment
of the remaining onsite tunnels pending further
monitoring and treatability studies. The primary
contaminants of concern  affecting the ground
water are metals including arsenic,  cadmium,
chromium, and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
constructing physical barriers for mine waste
piles (to reduce metals loading to surface water
and  human  health  risks from ingestion or
inhalation of metals); treating discharges from
the Burleigh tunnel passively through the use of
man-made wetlands; treating discharges from
the Argo  runnel actively along with  ground
water  pumped  from  the  immediate  area;
providing  an alternate  water  supply  where
needed; invoking an interim action  waiver of
ARARs for discharges from the National, Quartz
Hill, and  Big Five tunnels, and the Gregory
Incline, and invoking a technical impractical!ty
waiver for restoring ground  water  to  MCLs;
collecting  discharges from the National  and
Quartz Hill tunnels, and  Gregory Incline with
final disposition to  be  established pending
further monitoring and treatability studies; and
implementing  institutional  controls.     The
estimated  present worth cost for this remedial
action is $23,510,000, which includes  an annual
O&M cost of $1,204,000 for 30 years.

 SITE HISTORY/DESCRIPTION:

 The Chemical Sales (New  Location) (Operable
 Unit 1) site  is an  active  chemical sales  and
 storage facility in Commerce City, Adams and
 Denver Counties, Colorado.  Land use in the
 area is predominantly industrial, and there are
 six residences located on the northern portion of
 the site. The site is bounded by Sand Creek to
 the north and lies within the 100-year floodplain
 of the creek.  An estimated 30,000 people who
 reside near the site use the alluvial aquifer as the
 principal source of drinking water. Since 1976,
 Chemical Sales (CS) has used the site to  store
 and sell  organic chemicals  and  acids.   Site
 features include  a warehouse and tank  farm
 including an associated system of above-ground
 and underground storage tanks and pipelines.
 Between 1985 and 1990, three onsite chemical
 releases of hazardous substances  into the soil
 and ground  water from the CS facility  were
 reported. In 1985, approximately 200 gallons of
 methylene chloride were spilled into onsite soil
 during a chemical transfer.  The second release
 was in 1986 when rainwater contaminated with
 several VOCs was  discharged into a  nearby
 drainage ditch.   The third  release  occurred in
 1990, when   approximately  3,700 gallons  of
 methanol were spilled on  the ground surface
 near  the  CS  tank  farm.    Several  EPA
 investigations confirmed the release of hazardous
 substances into the ground water from the CS
 Property.  The site has been divided into three
operable  units for  remediation.   This ROD
addresses remediation of soil and ground water
contamination south  of Sand Creek, as OU1.
Future  RODs   will  address   other   site
contamination including the ground water plume
and  associated  contamination  (OU2),  and
residential  exposure to contaminated wells and
domestic water from the municipal water supply
(OU3).  The primary contaminants of concern
affecting the soil and ground water are VOCs
including PCE and TCE.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating contaminated  onsite soil using  vapor
extraction; treating air emissions with catalytic
oxidation; recirculating exhaust from the catalytic
oxidation  system  into the contaminated soil;
pumping and onsite treatment of ground water
in the source area and plume area  using air
stripping,  followed by reinjecting the  treated
water  from  the  source  area  wells  and
reinfiltrating treated water from the plume area
through onsite  discharge; monitoring ground
water, treated water, and air; providing public
notice   of  potential   health   threat  from
contamination ground water; and implementing
institutional controls including ground water use
restrictions. The estimated cost for this remedial
action  is  $2,081,000.   No O&M  costs were
provided for this remedial action.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 6,700-acre Hill Air Force Base (Hill AFB) site
is an active military facility situated between the
cities of Ogden and  Salt Lake City, covering
portions of Davis and Weber Counties, Utah.
This ROD addresses part  of  operable unit  2
(OU2),  which consists of two unlined disposal
trenches, seeps, and springs, and confined and
unconfined aquifers.  Land use in the area  is
mainly agricultural and residential. Both South
Weber and Hill AFB obtain drinking water from
deep wells in confined  aquifers.  Because the
base covers a large  area,  the Air  Force  has
grouped geographically adjacent contaminated
areas into seven OUs. From 1967 to 1975, Hill
AFB disposed of waste solvents and sludge from
degreasing  operations in the onsite disposal
trenches. It is estimated that 100,000 to 1,000,000
gallons  of  TCE  bottoms  from  the   solvent
recovery unit, sludge from vapor degreasers, and
plating-tank sludge bottoms were disposed of in
these trenches.  Federal investigations from 1983
to 1986 identified VOC contamination in onsite
and offsite ground water. As  a result of these
investigations,  Hill AFB began collection and
treatment of contaminated ground water from
seeps and springs in 1986.   In  addition, an
alternate water supply  was provided  to five
properties  to prevent the use  of contaminated
ground water  from seeps  and springs.  This
ROD addresses the interim remediation  of OU2
subsurface soil and ground water by removing
a  DNAPL  source  and   thus  preventing
contaminants from reaching aquifers currently
used as drinking water sources. A subsequent
ROD will provide a final remedy for OU2 soil,
ground  water, surface water,  and air.   The
primary contaminants of concern affecting the
soil and ground water are VOCs including PCE,
TCE, toluene, and xylenes.

SELECTED REMEDIAL ACTION:

The selected remedial action  for this  interim
remedy includes installing and  maintaining a
source recovery  system  to  remove  DNAPL
contamination  from the subsurface; pumping
DNAPL-contaminated ground water, with onsite
discharge to a  pretreatment facility  to separate
DNAPL from  ground water using a steam
stripper; temporarily storing the DNAPL onsite
in steel tanks, followed by transporting the waste
offsite for incineration; installing a pipeline from
the site  to  the  base  Industrial  Wastewater
Treatment Plant (IWTP); treating the pretreated
ground water at  the IWTP using air stripping,
followed by carbon adsorption; discharging the
treated water offsite to a POTW; and monitoring
DNAPL  collection   and  treatment   during
remediation  activities.  The estimated  present
worth cost for this remedial action is $3,710,000,
which  includes  an  annual  O&M  cost  of
$1,000,000 for 2 years.

PERFORMANCE STANDARDS OR GOALS:

Actual chemical-specific standards or goals will
be set in a future ROD.

                                  January 25,1991
SITE HISTORY/DESCRIPTION:

The Rocky Eats Plant (USDOE) site is part of the
6,550-acre  nuclear   weapons   research,
development,  production,   and   plutonium
processing   complex  in  Jefferson   County,
Colorado.  The plant is composed of the 450-acre
Rocky Flats  Plant (RFP)  security area and the
remaining buffer area.  Land use in the area is
predominantly  rural  and  agricultural  with
several  new   residential   areas  under
development. This ROD addresses operable unit
2 (OU2), which includes the 903 Pad and Lip,
and Mound and East Trenches Areas, which are
located southeast of the RFP.  The site lies within
the South Walnut  Creek and  Woman  Creek
drainage basins. The South Walnut Creek Basin
and Woman Creek surface water serve as a
source  of drinking water.   Since  1951,  the
Department of Energy  (DOE) used the site for
manufacturing components for nuclear weapons,
processing  plutonium,  and  fabricating,
machining, and assembling components from
metals.  A number of  past onsite storage and
disposal  activities  are  potential sources  of
contamination.   From  1958 to 1967, drums
containing radioactively contaminated oils and
solvents were stored onsite, with some of the
drums  corroding  and leaking approximately
5,000 gallons of liquid  into the soil.   During a
clean-up and removal effort of the drum storage
area, winds distributed plutonium to the south
and east. Prior to 1968, sanitary sewage sludge
and flattened drums contaminated with uranium
and  plutonium were  disposed of  in  onsite
trenches, and drums of uranium-contaminated
oil were burned in onsite pits. During the 1950's
and 1960's, reactive metals  including lithium,
and solvents were destroyed onsite. In addition,
various  bottled gases  were  detoxified  onsite
between 1982 and 1983. Current waste handling
Practices involve onsite and  offsite recycling of
hazardous materials, and offsite disposal of solid
radioactive materials at another DOE facility.
DOE has conducted a number of investigations
that revealed VOCs, metals, and radionuclides
above  background levels  in soil, sediment,
ground  water,  and  surface  water.   A  1969
clean-up action  attempted to remove corroded
and leaking drums of radioactive waste from an
onsite area, remove contaminated  soil, and cap
the soil.  In 1970, approximately  1,405 drums
containing radioactive waste were removed and
disposed  of offsite.   A  1990 ROD addressed
contaminated ground water. This ROD provides
an  interim remedy  for contaminated  South
Walnut Creek Basin surface waters as  part of
OU2.   The primary  contaminants of concern
affecting the surface water are VOCs including
carbon  tetrachloride,  PCE,  and  TCE;   and
radioactive materials.

SELECTED REMEDIAL ACTION:

The selected remedial action for this  interim
remedy includes collecting surface water using
diversion;  treating   surface  water   using
precipitation and cross-flow membrane filtration
to remove suspended solids and radionuclides,
followed  by liquid-phase activated carbon to
remove organic contaminants; discharging the
treated water onsite  to South  Walnut Creek;
conducting treatability studies; and monitoring
surface water. The estimated present worth cost
for this remedial  action is $4,850,600, which
includes an annual O&M cost of $361,600.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific surface water clean-up goals
will be based on the most stringent of State and
Federal allowable limits as set forth in ARARs,
and will apply to the final remedial action.

        ROCKY MOUNTAIN ARSENAL (OPERABLE UNIT 21), CO
                                    June 6, 1991
SITE HISTORY/DESCRIPTION:

The Rocky Mountain Arsenal (RMA) (Operable
Unit 21) site comprises part of  the 17,000-acre
RMA site, which is a former U.S.  Army chemical
warfare and incendiary munitions manufacturing
and assembly plant in Adams County, Colorado.
From the 1950's until late  1969,  the U.S. Army
used the RMA facility to produce  the nerve
agent   GB   (isopropylmethyl-phosphono-
fluoridate). In addition, between 1947 and 1982,
private industries leased major portions of the
plant's   facilities  to  manufacture   various
insecticides and herbicides.  From 1970 through
1982,  U.S.  Army facility  operations  have
primarily involved the destruction of chemical
warfare materials.  Because final  remediation of
the RMA site will take many years to complete,
13  interim  response  actions  (IRAs)  were
determined necessary prior to implementing the
final On-Post ROD. Operable Unit 21 (OU21),
the South Tank Farm Plume (STFP), is one of
several areas being addressed as part of the
Other Contaminated Sources IRA.  The STFP is
located in the southern half of sections 1 and 2
of the RMA site.  From 1947 to 1978, STF tanks
464A, 464B, and others were used intermittently
to  store  bicycloheptadiene  (BCHPD)   and
dicyclopentadiene  (DCPD) bottoms  generated
from pesticide manufacturing.   In  addition,
mixtures of BCHPD, DCPD, and fuel oil were
pumped onto the ground, or collected or buried
onsite during tank cleanings. From 1960 to 1963,
teakage  of  BCHPD/DCPD bottoms  occurred
from a  pipe  connected  to tank 464A,  and
additional spills occurred in 1964 and 1978.  The
e*act spill locations and amounts are generally
not known. Additionally, in 1948, a large spill of
benzene containing toluene and xylene
impurities occurred in the STF.  A number of
U.S. Army investigations have revealed ground
water contamination originating from the areas
of light  nonaqueous  phase  liquid  (LNAPL)
located near tank 464A.  Recent investigations
have  shown  that  the  STFP  does not pose
significant  risk  to  public   health  or   the
environment,  as originally  suspected, because
data  indicate  that  the plume  will not migrate
into nearby Lake Ladora or Lake Derby prior to
implementation of the final remedy.  In addition,
biodegradation of the plume may be occurring.
This  ROD  addresses interim  management  of
migration of the STFP and is consistent with the
Final   Response  Action.      The  primary
contaminants  of concern affecting  the ground
water are VOCs including benzene, toluene, and
xylenes.

SELECTED REMEDIAL ACTION:

The selected interim remedial action for this site
includes  performing one-time comprehensive
ground water monitoring throughout the STFP
to verify  the extent and migration rate of STFP
constituents and the existence of conditions
conducive for biodegradation  within the STFP;
and conducting annual ground water monitoring
including performing quarterly measurement of
STFP  water levels.  No cost  information was
provided for this interim remedial action.

                                 September 5,1991
SITE HISTORY/DESCRIPTION:

The Rocky Mountain Arsenal (RMA) (Operable
Unit 26) site comprises part of the 17,000-acre
RMA site, which is a former U.S. Army chemical
warfare and incendiary munitions manufacturing
and assembly plant in Adams County, Colorado.
From the 1950s  until late 1969, the U.S. Army
used the RMA  facility to  produce  the nerve
agent   GB   (isopropylmethyl-phosphono-
fluoridate). In addition, between 1947 and 1982,
private industries leased major portions of the
plant   facilities  to   manufacture   various
insecticides and herbicides.  Since 1970, U.S.
Army facility operations primarily have involved
the destruction of chemical warfare materials.
Because  final remediation of the RMA site will
take many years  to complete,  13  interim
response  actions  (IRAs)  were  determined
necessary  prior  to  implementing  the  final
On-Post ROD. Operable unit 26 (OU26), which
is  one of these  13 IRAs,  is composed of the
piping and equipment in the buildings in the
North and South Plants at RMA. From 1987 to
1989, the U.S. Army surveyed and  sampled the
former chemical process equipment and piping
in  the North and South Plants. In 1990, the U.S.
Army decontaminated piping and equipment in
some buildings in the North Plant, and sampled
2,354 1-ton containers.  This ROD  addresses
contaminated   piping  and   equipment  in
numerous  buildings  in the North and South
Plants, and contaminated 1-ton containers. This
IRA  will facilitate the final remedy  for the
cleanup  of chemical process  buildings and
structures, by  verifying  the decontamination
status of chemical process  piping, equipment,
and 1-ton containers, and decontaminating these
structures and 1-ton containers,  as necessary, to
allow for reuse or disposal of the equipment and
piping.  The primary contaminants of concern
affecting the debris and  air are  the chemical
agents  GB (Agent  GB,   Sarin),   HD  (Agent
Mustard), L (Agent Lewisite), and VX (Agent
VX).

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
sampling   to  determine   the  level  of
decontamination inside piping and equipment as
identified in  the sampling  operations in the
North and South Plants; decontaminating piping,
equipment,   and   1-ton   containers;   and
dismantling piping and equipment.  No cost
information  was  provided  for  this  interim
remedial action.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific standards for air are based on
Federal   regulations  and   include
GB 0.0001  mg/m1,  HD  0.003   mg/m3,

                                    March 29,1991
SITE HISTORY/DESCRIPTION:

The 18-acre Wasatch Chemical (Lot 6) site is an
active   chemical  production,  storage,   and
distribution  facility  in Salt  Lake City, Utah.
Land use in the area is predominantly industrial.
The  site lies one-half  mile east of  the Jordan
River,  within the center of  the  Jordan River
Valley.  The site overlies a thick aquifer that is a
regional source of potable water. Surface water
run-off  from the site is drained by a series  of
ditches, which ultimately discharge to the Great
Salt Lake. From 1957 to 1986, Wasatch Chemical
Company and other tenants  used the  site for
production, packaging, storage, and distribution
of various chemical products including industrial
chemicals,  acids,  solvents,   pesticides,   and
fertilizers.  Process  wastes including dioxins,
were  directed  toward  an onsite  evaporation
pond, stored in 40 drums, and also discharged
directly in the ground and possibly into the Salt
Lake City sewer system.  Noncompliance with
State  and  Federal  hazardous waste  storage
practices and disposal  standards prompted  a
number  of  the State  investigations, which
revealed elevated levels of VOCs in onsite soil
and sludge, and PCE in ground water. In 1986,
as part  of a removal action,  EPA removed 40
drums and  cylinders and other contaminated
materials  offsite.     This   ROD   addresses
contamination of onsite soil, sludge, and ground
water  as  a final  remedy.    The  primary
contaminants of concern affecting the  soil,
sludge,  and  ground  water are VOCs including
PCE,  TCE,  toluene,  and xylenes;  and other
organics including  pesticides,  herbicides,  and
dioxins.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating and consolidating 3,587 cubic yards of
contaminated soil and sludge and 650 gallons of
liquid waste in the former evaporation pond;
treating these materials  onsite using  in-situ
vitrification;   excavating  and   land  farming
1,111 cubic yards of hydrocarbon-contaminated
soil; sealing the surface of the site using asphalt
paving;  pumping and onsite  treatment of 20.4
million gallons of contaminated ground water
using air stripping; controlling air emissions with
carbon adsorption, if needed, followed by offsite
disposal   of  residuals;  and   implementing
institutional controls including deed and ground
water use restrictions.  The estimated  present
worth cost for this remedial action is $3,900,000,
which includes an estimated annual O&M cost of
$33,000 for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Soil clean-up goals are  based  on health-based
action levels and  include PCE 103,000 ug/kg,
TCE 22,000 ug/kg, and dioxin <1 ug/kg (based
on RCRA Land Disposal Restrictions). Ground
water action levels  are based on SDWA MCLs
and proposed MCLs, and include PCE 5 ug/1
(MCL) and TCE 5 ug/1 (MCL).

INSTITUTIONAL CONTROLS:

Deed and ground water use restrictions will be
implemented to prevent land and ground water
access and use at the site.

                                 September 11,1991
SITE HISTORY/DESCRIPTION:

The 3-acre Advanced Micro Devices (AMD) site
is an active semiconductor manufacturing facility
in Sunnyvale, Santa  Clara County, California.
The site is  part of  a  larger study area that
includes four operable  units  (OUs):  the  AMD
901  site, the  Signetics  site,  the 1-acre  TRW
Microwave   site,  and  a  100-acre   offsite
contaminated ground water plume. Land use in
the  area  is  predominantly  commercial  and
industrial. Residential property lies to the north
and west of the main facilities and overlies
portions of the offsite ground water OU. Six
aquifers are  associated with the study  area
including a deeper aquifer confirmed only at the
TRW  and   Signetics  sites.    Currently, the
contaminated ground water  is not used as a
drinking water supply,  but the State considers
several of the aquifers to be potential drinking
water sources. From 1969 to  the present, AMD
has  used  its  portion of the study area for
manufacturing  semiconductors  using organic
solvents, acids, and metals.  These substances
also were used in semiconductor manufacturing
at the Signetics and TRW sites from 1964 to the
present and from 1974 to 1986, respectively. As
a result of a leakage from the acid neutralization
system  at   the AMD  site,  a  number of
investigations  were  conducted  that revealed
extensive  contamination  of  onsite  soil  and
ground water.  Leakage from an underground
waste solvent storage tank at the Signetics site
and responses to an information  questionnaire
regarding an underground tanks investigation at
the  TRW  site  resulted  in  a  number of
investigations  that   revealed  extensive
contamination of soil and ground water. Several
initial remedial measures were conducted at the
AMD  OU.    During  1983  and 1984,   acid
neutralization   sumps   and  approximately
217 cubic  yards of  contaminated  soil  were
removed. From 1984 to 1988, remediation of
ground water was implemented using extraction
wells and dewatering sumps.   Several initial
remedial measures also were conducted at the
Signetics OU.  From 1982 to present, ground
water  has been  pumped from various  site
locations and treated using air stripping and
carbon adsorption, followed by air stripping to
control off-gases and reuse of the treated water
in industrial processes.  Contaminated soil has
been  removed  from three separate locations,
including 4,720 cubic yards of soil from a waste
solvent storage tank area in 1983.  In 1989, three
vapor extraction wells  were installed  to  treat
contaminated soil.   Several  initial  remedial
measures also have been conducted at the TRW
OU. From 1983 to 1984, an underground waste
solvent  storage tank and  120  cubic  yards of
onsite contaminated soil were removed. From
1984 to present, ground water has been pumped
and treated  using air stripping, followed by
onsite discharge to surface water.  In addition,
two ground  water extraction  systems pump
contaminated ground water from the 100-acre
offsite plume. The extracted water is treated at
a neighboring AMD facility using air stripping,
followed by  liquid phase granular activated
carbon polisher  and onsite discharge to surface
water,  or reuse by the  facility.   This  ROD
collectively addresses final remediation of soil
and ground  water in the four  separate OUs
within   the   study  area.     The  primary
contaminants of concern affecting the soil and
ground water are VOCs including PCE and TCE;
and other organics.

SELECTED REMEDIAL ACTION;

The selected remedial action for this site includes
separate remedies for the four different OUs of
the study area.  The remedy for the AMD OU
includes  excavating 37 cubic  yards of onsite
contaminated   soil,  followed  by  offsite
incineration and/or disposal, and backfilling the
                                            417

excavation with clean soil; and continuing onsite
pumping and treatment of ground water using
air stripping and carbon adsorption of off-gases,
followed by reuse of the treated water.  The
remedy for the Signetics OU includes expanding
the onsite  soil vapor extraction system  and
continuing  onsite pumping and treatment of
ground water using air stripping, followed by
aqueous-phase carbon polishing, reuse  of the
treated water, and vapor-phase carbon treatment
of the effluent air stream.  The remedy for the
TRW OU includes continuing onsite pumping
and  treatment  of  ground  water  using  air
stripping, followed by onsite discharge of treated
water to surface water.  The remedy for the
offsite ground water OU includes continuing and
expanding the pumping and treatment system
for  contaminated ground  water  using  air
stripping and aqueous-phase carbon  adsorption,
followed by reuse of the treated water or onsite
discharge   to  surface  water,  and   offsite
regeneration of spent carbon. Each OU also will
involve continued ground water monitoring, and
implementing institutional  controls including
deed and ground water use restrictions.  The
estimated present worth cost for the  remedial
action for all OUs is $11,900,000, which includes
an estimated O&M cost of $225,000 for the AMD
OU; $236,000 for the Signetics OU; and $255,000
for the offsite ground water OU.   No annual
O&M cost was provided for the TRW OU.

                     ADVANCED MICRO DEVICES #915, CA
                                    August 26,1991
 SITE HISTORY/DESCRIPTION:

 The Advanced Micro Devices (AMD) #915 site is
 an active semiconductor manufacturing facility
 in  Santa Clara County, California.   The site
 consists of approximately 5 acres and contains
 three physical structures, the largest of which is
 a 116,000-square-feet building known as  AMD
 915.  The site is in the Santa Clara Valley, and
 the  facility  lies  within an  industrial  park
 bordered by  residential  areas-   Ground  water
 from  this basin provides up  to 50 percent of the
 municipal  drinking  water for  1.4  million
 residents of the Santa Clara Valley.  The site
 overlies three aquifers, one of which is known as
 the B aquifer, which is approximately 20 to 100
 feet below the surface. AMD #915 was built in
 1974,  and onsite manufacturing processes have
 involved the use of solvents, caustics, and acids.
 Eleven chemical storage or treatment areas have
 been  documented  at  the  AMD #915 facility
 including three underground acid neutralization
 systems, two above-ground drum storage areas,
 and six underground tank complexes.  Two  of
 the  acid  neutralization  systems remain   in
 operation, as well as one drum storage area, and
 two tank  complexes.   Records indicate  that
 solvent wastes and other materials were stored
 in  underground tanks,  and as many as 28
 separate underground  tanks may have been  in
 service  at  various  times.    In  1981,  site
 investigations discovered  soil  contamination
 during  a planned  underground storage tank
 removal. Two leaking underground tanks were
 identified, and 7,000 cubic yards of contaminated
 soil were removed. The majority of these  tanks
 now  have been   removed  from service  or
 replaced. In 1982, ground water contamination
 also was addressed and found to be limited  to
 the B aquifer.  Additional offsite sources of
ground water  contamination   may  have  a
 significant effect on the AMD #915 site including
commingling of ground water contamination.
The most notable of these are Advanced Micro
Devices  901/902 facilities, Signetics, and FEI
Microwave.  Two interim remedial actions for
soil  were completed  during 1981 and  1982,
including offsite removal and disposal of a waste
solvent tank,  and  the removal  of one  acid
neutralization system and 5,500 cubic yards  of
soil.   In 1982, ground water pumping  and
treatment using  air  stripping  and  carbon
adsorption began onsite using existing building
dewatering sumps. This was supplemented with
the installation of a series of wells during 1982
and 1988. This ROD addresses remediation  of
onsite contaminated ground water.  The primary
contaminants of concern affecting the ground
water  are   VOCs  including benzene,  TCE,
toluene, and xylenes; other organics; and metals
including arsenic and chromium.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
continuing the operation of eight existing ground
water extraction wells; and treating contaminated
ground water  onsite using air stripping  and
carbon adsorption, followed by discharge of the
treated  water  onsite to surface  water.   The
estimated present worth cost for this remedial
action is $2,100,000.  This figure represents the
O&M costs  for 30 years  since the  system  is
already in place as an interim measure and no
additional capital costs are required.

PERFORMANCE STANDARDS OR GOALS:

Ground water clean-up standards are based on
the more stringent of Federal or State MCLs for
drinking water.   Chemical-specific  goals for
ground  water include PCE 5  ug/1 (MCL),  and
TCE 5 ug/1 (MCL).

                           ATLAS ASBESTOS  MINE, CA
                                   February 14,1991
SITE HISTORY/DESCRIPTION:

The 450-acre Atlas Mine Area is part of the Atlas
Asbestos Mine site in Fresno County, California.
The site consists of four geographically distinct
areas (the  Atlas  Mine Area, the Clear Creek
Management Area (CCMA), the Ponding Basin
of the California Aqueduct, and the  City of
Coalinga).  The Atlas Mine Area is on rural land
owned by the Federal government and private
parties, and  surrounding land is  used for
mining, ranching, farming, and recreation.  The
Mine Area includes three open pit asbestos mine
surfaces, stockpiles of asbestos waste material, an
abandoned mill building, a settling  pond, and
debris.  Construction of an asbestos  mill at the
Atlas Mine began in 1962, and onsite asbestos
mining and milling activities occurred from 1967
to 1979. Approximately 3 million cubic yards of
asbestos  ore  and asbestos mill  tailings from
onsite operations were  bulldozed  into piles
adjacent to the mill building. In 1976 and 1980,
the Atlas Mine was cited for violating asbestos
emissions  standards.   In  early 1980,  after
detecting elevated levels of asbestos in water
samples from the California Aqueduct, the State
concluded  that additional corrective measures
were   necessary   to  prevent   mine-   and
mill-generated  asbestos   from   entering  the
drainage basins.  Further State  investigations
identified high concentrations of asbestos in the
Mine Area  soil, surface water, and air.  A 1989
ROD  for the City of Coalinga  Operable Unit
addressed cleanup of asbestos-contaminated soil
in  Coalinga,  California  by   burying  the
contaminated material in a waste management
unit with an impermeable cap.  This ROD is
designed to control the release of asbestos from
the Mine Area.  No actions are proposed at this
time for the CCMA or the Ponding Basin of the
California Aqueduct.  In 1992, EPA will evaluate
the Department of  Interior Bureau of  Land
Management's revised land use plan  for CCMA
to determine if the plan is adequate to minimize
airborne asbestos emissions, and the U.S. Bureau
of Reclamation and  California Department of
Waste Resources actions to minimize airborne
emissions from the Ponding Basin to determine
if further action  is  necessary.  The primary
contaminant  of concern  affecting  the  soil,
sediment, debris,  surface  water,  and  air  is
asbestos, an inorganic.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
paving  the road  through  the Mine  Area or
implementing an appropriate road maintenance
alternative;  constructing   stream  diversions,
sediment  trapping  dams, and  other  slope
stabilization elements; instituting a verification
sampling plan involving surface water modeling
and surface water and stream bed sampling, as
necessary;  conducting  a  revegetation  pilot
project, and implementing revegetation if found
to be technically  feasible  and  cost-effective;
dismantling  the  mill  building  with  offsite
disposal along with other debris from the Mine
Area; and implementing institutional controls
including deed and land use restrictions, and site
access restrictions  such  as  fencing.    The
estimated present worth cost  for this remedial
action is $4,286,000, which  includes an annual
O&M cost of $19,000.

PERFORMANCE STANDARDS OR GOALS:

All diversion  and drainag^  facilities will be
designed and constructed to accommodate the
anticipated volume of  precipitation and peak
flows from surface  runoff in a 25-year, 24 hour
storm.   All tailings will  be protected from
100-year peak  stream flows.  Quantification of
risk reduction is difficult because asbestos from
natural and disturbed  areas  will continue to
enter  the surface water; however, a verification
sampling plan will be implemented to confirm
that   an  appropriate  reduction  in   asbestos
transport is achieved.

                                     June 28,1991
SITE HISTORY/DESCRIPTION:

The CTS Printex site is an inactive printed circuit
board manufacturing facility in Mountain View,
Santa   Clara  County,  California.     Land
surrounding  the  site is  used  for  industrial,
commercial,   residential,  and  agricultural
purposes.    The  site   overlies  two   major
water-yielding zones,  a  shallow  and deep
aquifer, which are suspected to be hydraulically
continuous.  Historical ground water use in the
area  surrounding the site  includes  private
water-supply wells for homes and agriculture
prior to the construction of  public water and
sewer connections in 1984. Site features include
a flammable materials storage  shed area, an
industrial wastewater sump used to neutralize
and discharge waste to the POTW, a "wet floor"
building  used   for   both   wet   and  dry
manufacturing processes, a materials and waste
storage warehouse, and various office buildings.
From  1981  to 1985,  the CTS Printex site
manufactured printed circuit boards at its onsite
facilities.  Site investigations by CTS Printex in
1985 established that the "wet floor" building and
the wastewater sump areas were the sources of
onsite soil and ground water contamination, and
that the release of contaminants was attributed to
deterioration of the concrete bases. In 1986, the
State certified closure of the former CTS facility.
In 1987, the State required  CTS to implement the
following interim  remedial actions for soil and
ground  water:   destroying  and   removing
contaminated  onsite  structures,   removing
residual metals sludge and process debris from
the site, hydroblasting interior areas of structures
exposed to contaminants,  excavating the sump
and contaminated  soil, and installing and
operating a ground water extraction system.
This ROD addresses contaminated onsite ground
water.  The primary contaminants of concern
affecting the ground water are VOCs including
benzene, PCE, TCE, and toluene.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
continuing the current ground water extraction
system, including discharging  the untreated
water to the sanitary sewer for offsite treatment
at the POTW; and conducting ground  water
monitoring.  Passive air stripping is created by
passing water  through  the  sewer collection
system and through the sewage treatment plant.
The  estimated  present  worth  cost  for this
remedial action is $786,000, which includes an
estimated O&M cost of $104,700 for 15 years.

PERFORMANCE STANDARDS OR GOALS:

Ground water clean-up goals are based on the
more stringent of  Federal MCLs or  non-zero
MCLGs, or State MCLs. Chemical-specific goals
include benzene 1 ug/1  (State), PCE 5 ug/1
(MCL), TCE 5 ug/1 (MCL), and toluene 100 ug/1
(State). Action-specific goals include compliance
with the City of Mountain  View's discharge
requirement for the sanitary sewer, which is total
organics  equal  to 1  ug/1  at  the point of
discharge.

 SITE HISTORY/DESCRIPTION:

 The  2,777-acre Castle Air  Force  Base  is a
 Strategic Air Command training base 6 miles
 northwest of the City of  Merced in Merced
 County,  California.  Land use  in  the area is
 predominantly agricultural.  Several irrigation
 canals and laterals are located within 1 mile of
 the base including Canal Creek, which borders
 the base on its southwest boundary and receives
 runoff  from  the base  and  irrigated  land
 downstream. At least 20 agricultural wells are
 located within 3 to 4 miles of the  site, and a
 number of residential and municipal wells are
 located within 2 miles of the site.  Since 1941, the
 site has been used as a military air training base.
 Fire training activities, as well as aircraft and jet
 engine maintenance activities including metal
 plating and  processing, have occurred  onsite.
 Both processes involve the use of fuels, solvents,
 and  chemicals and have  generated municipal
 and  chemical wastes.   During  routine  well
 sampling, the State  identified  elevated  TCE
 concentrations in ground water in the shallow
 aquifer beneath and south of the site. In 1984,
 the base was required not only to implement
 remedial measures to correct this identified
 contamination but also to prevent future ground
 water degradation from waste discharges.  The
 site has been divided into operable units (OUs)
 for remediation. This ROD provides an interim
 remedy for  the main TCE  plume,  as OU1.
 Future RODs will  address remaining soil  and
ground water contamination.   The primary
contaminants of concern affecting the ground
 water are VOCs including benzene, PCE,  and
TCE.

SELECTED REMEDIAL ACTION:
The selected  remedial action for this interim
remedy includes onsite pumping and treatment
of ground water using air stripping, followed by
natural biological enhancement to accelerate the
release   and   degradation   of   hazardous
constituents in the saturated zone; reinjecting the
treated  ground  water  onsite  to  maintain
hydraulic  control and avoid depletion of  the
aquifer; treating emissions from the air stripping
process using granular activated carbon; and
treating the emissions abatement unit by onsite
steam regeneration, and disposing of the liquid
condensate offsite. The estimated present worth
cost for this remedial action is $28,445,000, which
includes an annual O&M cost of $2,744,000.

PERFORMANCE STANDARDS OR GOALS:

Ground water clean-up goals based on MCLs
and risk  levels  will  be  established  in  a
subsequent ROD.

                                      June 28,1991
 SITE HISTORY/DESCRIPTION:

 The 17-acre FMC (Fresno Plant) site is an active
 pesticide  manufacturing  facility  in   Fresno,
 California. Surrounding land use is primarily
 industrial, but  several residential  areas are
 within 1 kilometer of the site.  The site overlies
 two  unconsolidated sand  zones  that  are  a
 potential source of ground water, and have been
 contaminated by site operations.   Since  1931,
 various agricultural product  operations  have
 been  conducted   onsite   including   sulfur
 processing,   and   fertilizer  and   pesticide
 manufacturing.      Wastewater  from   liquid
 pesticide  formulation  was  discharged  to  a
 4.92-acre area of the site via a trench during the
 1960's and  1970's.   From  1963  until  1974,
 wastewater from oil drum cleaning operations
 was stored in an above-ground tank and  was
 sprayed on a concrete evaporation slab in an oil
 drum yard.  A former disposal pond area was
 used for the disposal of fertilizer process wastes
 from 1967 to 1972.  From 1972 until 1983,  a
 wastewater evaporation pond was used for the
 discharge  of  wastewater,  including oil drum
 washing rinsate.   From  1976 until  1988,  a
 rainwater  percolation pond  was used to collect
 surface run-off from non-production areas of the
 site. These waste disposal practices have led to
 contamination of onsite soil and ground water.
 In  1980,  FMC  excavated  a  portion  of  the
 contaminated soil in the oil drum yard.  In 1983,
discharge  to the wastewater evaporation pond
 was discontinued.  In 1985,1,500 cubic yards of
contaminated soil were excavated from the waste
pond.   In 1989, this pond  was lined  with  a
synthetic liner.   Investigations by FMC under
EPA oversight from 1989 to  1991 characterized
and   quantified  site  contamination,  affected
media, and probable source areas.   This ROD
provides for remediation of onsite source areas
and  restoration  of  ground  water  as a  final
remedy. The primary contaminants  of concern
affecting  the  soil  and  ground  water  are
organochlorine   and   organophosphorous
pesticides although VOCs including PCE, TCE,
toluene, and xylenes; other organics including
dioxin, PAHs, and phenols; and metals including
arsenic, chromium, and lead are also present.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
excavating approximately 25,000 cubic yards of
contaminated soil from onsite source areas, and
treating  the  soil using  soil  washing  and
stabilization   technologies;   backfilling   the
excavated areas  with  treated  soil; treating soil
wash water using carbon adsorption; capping
unpaved  and excavated areas including  the
4.92-acre wastewater evaporation pond, oil drum
yard, and percolation pond; onsite pumping and
treatment of ground  water using  filtration, air
stripping, and carbon  adsorption; reinjecting or
reusing  the  treated  ground  water  onsite;
providing an alternate water supply to onsite or
offsite  well users, if necessary,  to  eliminate
adverse  affects  to ground  water  treatment;
monitoring  ground water;  and implementing
institutional controls including deed, land, and
ground  water use restrictions.  The estimated
present  worth cost for this remedial action is
$17,310,681, which includes an annual O&M cost
of $445,163 for 30 years.

PERFORMANCE STANDARDS OR GOALS;

Clean-up  standards for soil  are  based on a
carcinogenic risk level of 10"4  and an HI=1.
However, when combined  with capping  and
institutional controls,  the selected soil remedy
attains a 10'6 carcinogenic risk level.  Ground
water clean-up standards are based on the more
stringent of Federal or State MCLs or non-zero
MCLGs.  If these standards do not exist, State
Action Levels, site-specific Health-Based Levels,
or Quantification Limits will be used.

      INDIAN BEND WASH AREA (OPERABLE UNITS 1, 4, 5,  6), AZ
                                 September 12,1991
 SITE HISTORY/DESCRIPTION:

 The Indian Bend Wash Area site is an active
 electronics manufacturing and  metal  plating
 facility located in the Cities of Scottsdale and
 Tempe, Maricopa County, Arizona,  The site
 consists of two study areas, the North Indian
 Bend Wash (NIBW) and  South Indian  Bend
 Wash (SIBW), both of  which contain portions
 that lie in the 100-year floodplain of the IBW.
 The NIBW area  is the  focus of  this ROD and
 consists of four operable units; 1, 4, 5, and  6,
 Land use within the 10-square-mile NIBW study
 area is mainly residential, commercial/industrial,
 and developed  open space (parks  and  golf
 courses).     In   addition,  the  Salt  River
 Pima-Maricopa Indian Community maintains a
 portion of NIBW as Cropland. The Indian Bend
 Wash provides the major surface water drainage
 for  the  NIBW  area.    Since  1950, various
 electronics  manufacturing and  metal  plating
 facilities, as well  as other industries, have been
 active  at NIBW.    Onsite  operations  have
 included   the  use and disposal  of organic
 solvents.  During operations, waste solvents and
 waslewater containing  solvents  were released
 from solvent storage tanks and pipes directly to
 dry wells, surface pits, ponds, lagoons, and the
 ground surface.  In 1981, the State conducted
 well sampling and identified VOC contamination
 in  several municipal  supply  wells.    EPA
 investigations have concluded that the methods
 used   for  solvent  disposal   led  to   soil
contamination, which in turn acted as a source of
contamination for underlying alluvial units. A
 1988 ROD provided for remediation  of the
middle and deep alluvial units at NIBW.  This
ROD addresses contamination in the  vadose
zone and in the upper alluvial unit within the
NIBW area. However, because the vadose zone
overlies the upper alluvial unit, which overlies
the middle and  deep alluvial units, remedial
actions documented in this ROD are dependent
upon successful completion of the  1988 ROD.
The primary contaminants of concern affecting
the soil and shallow ground water are VOCs
including benzene, PCE, TCE, and toluene; other
organics;   and  metals   including   arsenic,
chromium, and lead.  EPA has designated 13
areas at NIBW for potential contamination in the
vadose  zone.   Twelve  of these  areas  are
designated by number.  The 13th area is in the
vicinity of several City of Scottsdale ground
water supply wells.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
installing  a soil  vapor extraction  system for
Areas 7 and 8 consisting of soil vapor extraction
wells, a manifold collection system, a vacuum
pump, and a  vapor-phase  carbon  adsorption
system;   installing   additional  soil   vapor
monitoring wells to continue investigations in
Areas 3, 5, 6,9,11, and 12 with either soil vapor
extraction  or  no  further action remedies as
needed; conducting no further action for Areas
1, 2, 4, 10, and the City of Scottsdale wells;  and
ground water monitoring  in the upper alluvial
unit. The  estimated present worth cost for this
remedial action is a minimum of $21,576,000,
depending upon  the  need  for  soil  vapor
extraction  in Areas 3, 5, 6, 9, 11, and 12, which
includes an annual O&M co&t of at least $935,000
for 30 years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil and ground water criteria
are  based on the more stringent of State water
quality standards,  Federal  MCLs, or non-zero
MCLGs.   These criteria include PCE  5 ug/1
(MCL), TCE 5 ug/1 (MCL), toluene 1000 ug/I
(MCL), arsenic 50 ug/1 (MCL}, chromium 50
ug/1 (State), and lead 50 ug/1 (MCL).

                                September 27,1991
SITE HISTORY/DESCRIPTION:

The  80-acre  Mesa  Area  Ground  Water
Contamination   site  is  a   semiconductor
manufacturing  facility  in  Mesa,  Maricopa
County, Arizona.   Land use in the area  is
predominantly industrial and residential.  The
site  overlies two aquifers: a  Lower Alluvial
Aquifer (LAA), which is used by the residents of
Mesa as a drinking water source, and an Upper
Alluvial Aquifer (UAA).  Since 1966, Motorola,
Inc., has used the site for the production of
semiconductors and the storage of chemicals in
an  underground  storage system.     Onsite
manufacturing processes  involve the use of
solvents, acids, and  bases. In 1983, Motorola
identified VOCs including TCE, in ground water
originating   from  the  LAA.    Subsequent
investigations by Motorola revealed high levels
of VOC-contaminated soil in the main chemical
handling area,  and  VOC  and  chromium
contamination in the UAA. From 1983 to 1987,
Motorola performed a partial closure  of the
underground waste solvent storage system under
RCRA  authority.   In 1984, Motorola installed
ground water monitoring wells, later  converted
these  into   extraction  wells,  and   pumped
contaminated ground  water  from the UAA.
Since 1987, as a  result of Motorola's actions,
contamination  levels have been  consistently
below  MCLs.    However,   by  1991,  the
contaminated ground water plume had migrated
to over 1 mile southeast of the site. In  1991, EPA
dropped the Mesa Ground Water Contamination
site from the NPL and referred the site to the
RCRA  program because the  site  is a  RCRA
facility, the ground water contamination is solely
from  the  Motorola facility,  and no  public
drinking  water   supply  wells  have  been
contaminated. This action will be implemented
by the PRP under State supervision, and
incorporated as a component of the Corrective
Action Plan under RCRA. This ROD documents
final  remediation  of  contaminated  soil  and
ground water.  The primary contaminants of
concern affecting the soil and ground water are
VOCs including PCE and TCE.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating shallow onsite soil using soil vapor
extraction, controlling  VOC emissions using
carbon adsorption, followed  by offsite disposal
of carbon residuals; onsite and offsite pumping
of contaminated ground  water; treating  the
ground   water  onsite   using   vacuum
degasification, followed by carbon adsorption to
remove VOCs; discharging  the treated water
from  the  degasifier to the deionized water
treatment plant for reuse in manufacturing and
other  facility processes; disposing of remaining
wastewater at a POTW; and  rehabilitating two
deep  industrial ground water supply wells  to
prevent them  from acting  as  conduits  for
contaminant plume migration from the upper to
the lower aquifer. The estimated present worth
cost for this remedial action is $7,144,000, which
includes an annual O&M cost of $581,000 for 13
years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil clean-up goals are based
on State standards, and include PCE 14 mg/kg.
Chemical-specific ground water clean-up goals
are based on SDWA MCLs, and include PCE 5
ug/1 and TCE 5 ug/1.

SITE HISTORY/DESCRIPTION:

The  3-acre Micro Storage/Intel Magnetics site
consists of a former microcomputer disk drive
manufacturing facility and a magnetic bubble
production and testing facility in Santa Clara,
Santa Clara County, California. Land use in the
area   is  predominantly  industrial,  although
approximately 300,000 people reside within a
3-mile  radius of the site.  In addition,  the site
overlies two shallow aquifers zones, which in
turn, overlie  the Santa  Clara Valley  ground
water basin, the primary drinking water source
for the 1.4 million residents of the Santa Clara
Valley.   From 1985 to  1986,  Micro  Storage
Corporation (MSC) researched, developed, and
manufactured   microcomputer   disk   drives.
Chemicals used onsite were stored in an external
shaded storage area in 55-gallon drums. From
1978 to 1987, Intel  Magnetics (IM), a magnetic
bubble production and testing facility, operated
both an underground solvent tank used  to store
waste   solvents,   and  an  inorganic  acid
neutralization system.  As a result of  possible
improper storage procedures at both facilities, a
number  of  State  and  EPA  investigations
identified  VOCs including benzene, TCE, and
TCA, and other organics  in the ground water
aquifer  beneath  the  site.  Interim remedial
measures have included: extracting contaminated
ground  water  at  both  sites;  removing  all
chemicals stored on the combined MSC/IM site;
and replacing the underground storage tank and
excavating  contaminated  soil at  the IM site.
Treated ground water is discharged to a storm
sewage  system tributary  of nearby Calabazas
Creek.   This  ROD addresses  ground water
contaminated by past facility operations.  The
primary contaminants of concern affecting the
ground water are VOCs including benzene, PCE,
TCE, and toluene; and other organics.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
continuing   ground   water  extraction   and
treatment with carbon adsorption until clean-up
standards are achieved in all combined MSC/IM
site monitoring wells; installing and sampling a
minimum  of  two   new  monitoring  wells;
hydraulically contain  the entire  93,000 cubic
yards ground water  plume  above clean-up
standards; maintaining hydraulic control to
prohibit the  further  vertical  and  horizontal
migration  of  the   ground water  pollution;
quarterly  ground  water  monitoring  at  the
combined  MSC/IM  site during  the clean-up
period; treating the extracted ground water with
an   existing  carbon  absorption   system;
discharging the treated ground water onsite to
Calabazas  Creek;  and  implementing deed
restrictions onsite. The estimated present worth
O&M cost for this remedial action ranges from
$630,000 to $1,100,000 for 10 years.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific ground water clean-up goals
are based on the  more stringent of Federal  and
State  MCLs  standards, and include  benzene
1 ug/1, PCE  5 ug/1, TCE 5  ug/1, and  toluene
100 ug/1.

INSTITUTIONAL CONTROLS:

Deed restrictions will be implemented to prohibit
the use of onsite shallow  ground water  and
control other subsurface activities.

 SITE HISTORY/DESCRIPTION:

 The Monolithic Memories (MM) site is a former
 semiconductor manufacturing facility located in
 Sunnyvale  and Santa Clara, California.  Land
 surrounding the site is used for commercial and
 light industrial purposes. The site lies within the
 confined area of the Santa Clara Valley ground
 water basin, which consists of various upper and
 lower aquifer zones. Ground water  from this
 basin provides up to 50 percent of the municipal
 drinking water for Santa Clara Valley  residents.
 Remediation of the MM site has been combined
 with another National Priorities List (NPL) site.
 National Semiconductor (NSC),  because  both
 sites  contribute  to the same  ground  water
 contamination   problem.    The  combined
 remediation has been divided into two operable
 units  (OUs). This ROD addresses GUI, which
 consists of  three subunits.  Subunit 1 includes
 the 60-acre NSC facility, which contains more
 than 20 buildings used for administrative offices,
 laboratories, and semiconductor manufacturing;
 and the 10-acre United Technology Corporation
 facility,  which was used to develop and test
 rocket propellants.  Subunit 2 includes the MM
 facility,  currently owned by  Advanced Micro
 Devices, and consists of buildings used for office
 space and semiconductor production facilities.
 Subunit 3 consists  of the areas downgradient
 from  Subunits 1 and 2 and  extends  to the
 leading   edge  of  the  contaminant  plume.
 Semiconductor manufacturing activities took
 place  onsite at NSC beginning in  1967, and  at
 MM in 1970, and continued until  1989.  Virgin
 solvents  and  acids  used  in semiconductor
 manufacturing  processes  were   stored   in
 above-ground tanks and storage drums.  Waste
 solvents  were  stored  in  underground  and
above-ground  tanks, and  acid  wastes  were
 treated in underground and above-ground tanks
or underground neutralization sumps. In 1982,
NSC and MM conducted preliminary
 assessments of soil and ground  water near
 underground  storage  tanks and  sumps,  in
 response to a  state-initiated storage tank leak
 detection program. As a result, both NSC and
 MM removed tanks, sumps, and soil from areas
 containing  elevated concentrations  of solvents.
 In addition, in 1984 and 1986, NSC installed
 offsite and onsite  ground  water extraction
 systems,  and  MM installed  onsite extraction
 systems in  1986 and 1988. This ROD addresses
 remediation of contaminated soil on the facility
 property and ground water in the upper aquifer
 zone as OU1.  OU2 will address remaining soil
 and ground water problems associated with the
 western  portion  of   the   ground   water
 contaminant plume.  The primary contaminants
 of concern  affecting the soil and ground water
 are VOCs including benzene, PCE, TCE, toluene,
 and xylenes; and other organics including PAHs
 and phenols.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 treating contaminated soil in Subunits  1  and 2
 onsite using soil vapor extraction, with carbon
 adsorption  to  control  emissions,  if required;
 excavating and surface aeration of contaminated
 soil, if necessary; pumping and onsite treatment
 of contaminated ground water by expanding the
 existing extraction system and adding an ozone
 oxidation treatment system to the  current air
 stripper  treatment  systems; controlling  air
 emissions from the air strippers using  carbon
 treatment, if necessary; discharging the treated
 ground water onsite to storm sewers; monitoring
 ground water;  and implementing institutional
 controls  including deed restrictions.    The
 estimated present  worth cost for this remedial
action is $8,400,000, which includes a  30-year
operation  period.   O&M  costs  were not
provided.

 SITE HISTORY/DESCRIPTION:

 The Signetics  site is an active  semiconductor
 manufacturing facility in Sunnyvale, Santa Clara
 County, California.  The site is part of a larger
 study  area that includes  four  operable units
 (OUs):  the Signetics site, the 3-acre Advanced
 Micro Devices (AMD) 901  site, the 1-acre TRW
 Microwave  site,  and  a   100-acre  offsite
 contaminated ground water plume. Land use in
 the  area  is  predominantly  commercial  and
 industrial. Residential property lies to  the north
 and west of the main facilities and  overlies
 portions of the offsite ground water OU.  Six
 aquifers are associated with the  study  area
 including a deeper aquifer confirmed only at the
 TRW  and Signetics  sites.    Currently,  the
 contaminated ground water is  not used as a
 drinking water supply, but the State considers
 several of the aquifers to be potential  drinking
 water  sources.   From  1964 to the   present,
 Signetics used  its portion of the  study area for
 manufacturing  semiconductors  with  organic
 solvents, acids, and metals.  These substances
 also were used in semiconductor  manufacturing
 at the AMD and TRW sites from 1969 to  the
 present and from 1974 to 1986, respectively.  As
 a result of a leakage from an underground waste
 solvent storage  tank  at the Signetics site, a
 number of investigations  were conducted that
 revealed extensive contamination of onsite soil
 and ground water.   Leakage from  the acid
 neutralization system at AMD and responses to
 an  information questionnaire  regarding  an
 underground   tanks   investigation at  TRW
 resulted in a number of investigations  that also
 revealed extensive contamination of onsite soil
 and ground water at both of these sites. Several
 initial remedial measures were conducted at the
 Signetics OU.   From 1982 to present, ground
 water  has been  pumped  from various site
 locations and treated  using  air  stripping and
carbon adsorption, followed by air stripping to
control off-gases and reuse of the treated water
in industrial processes.  Contaminated soil has
been  removed  from three separate locations,
including 4,720 cubic yards of soil from a waste
solvent storage tank area in 1983.  In 1989, three
vapor extraction wells were installed  to  treat
contaminated soil.   Several initial  remedial
measures also have been conducted at the AMD
OU. In 1983 and 1984, acid neutralization sumps
and about 217 cubic yards  of contaminated soil
were  removed.  From 1984  to 1988, remediation
of  ground  water  was implemented using
extraction wells and dewatering sumps. Several
initial remedial  measures  also  have  been
conducted at the TRW OU.  From 1983 to 1984,
an underground waste solvent storage tank and
120 cubic yards of onsite contaminated soil were
removed.  From 1984 to present, ground water
has  been  pumped and   treated  using  air
stripping, followed by onsite discharge to surface
water. In addition, two ground water extraction
systems pump contaminated ground water from
the 100-acre offsite plume.  The extracted water
is treated at a neighboring AMD facility using
air stripping, followed by liquid phase granular
activated carbon polisher , with onsite discharge
to surface water or  reuse by the facility.  This
ROD collectively addresses final remediation of
soil and ground water in the four separate OUs
within  the  study   area.    The   primary
contaminants  of concern affecting the soil and
ground water are VOCs including PCE and TCE.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
separate remedies for  the  four different  OUs.
The  remedy  for the  Signetics OU  includes
expanding  the  onsite  soil  vapor  extraction
system; and continuing onsite pumping  and
treatment of ground water using air  stripping,
followed  by aqueous-phase  carbon  polishing,
reuse  of  the  treated water, and vapor-phase
carbon treatment of the effluent air stream.  The
remedy for the AMD OU includes excavating 37
                                            439

backfilling  the  excavation  with clean  soil;
continuing onsite  pumping and treatment of
ground  water using air stripping and carbon
adsorption of off-gases, followed by reuse of the

includes  continuing  onsite  pumping  and
treatment of ground water using air stripping,
followed by onsite discharge of treated water to
surface  water.   The  remedy for the  offsite
ground  water  OU includes continuing  and

for   contaminated  ground   water  using air
stripping and aqueous-phase carbon adsorption,
followed by reuse of the treated water or onsite
discharge  to  surface   water,  and   offsite

involve continued ground water monitoring, and
implementing institutional  controls  including
deed and ground  water use restrictions.  The
estimated present  worth cost for the  remedial
action for all OUs is $11,900,000, which includes
an estimated annual O&M cost of $236,000 for
the Signetics OU; $225,000 for the AMD OU; and
$255,000 for  the offsite ground water OU.  No
annual O&M cost was provided for the TRW
OU.

                                 September 27,1991
 SITE HISTORY/DESCRIPTION:

 The 35-acre  Sola  Optical  site is an  active
 ophthalmic  lens  manufacturing   facility  in
 southern Sonoma County, California. Land use
 in the surrounding area  is mixed  residential,
 manufacturing, commercial, and undeveloped.
 Adobe Creek is located 1,500 feet west of an
 onsite building. The City of Petaluma utilizes an
 unconfined aquifer, which underlies the site, as
 a drinking water source. In 1982, Sola identified
 low levels of solvents in  onsite ground water
 near six underground solvent storage tanks used
 to store TCA, acetone, and methanol.  In 1983,
 the  San Francisco Regional  Water  Quality
 Control Board  (SFRWQCB) directed  Sola to
 investigate ground  water  contamination at the
 site. In 1985, Sola independently excavated and
 removed the underground tanks along with the
 gravel backfill and 3 to 5 feet of native soil from
 the sides and bottom of the excavation. In 1987,
 the  SFRWQCB ordered  Sola  to construct  a
 ground water extraction and treatment system
 and, in  1988,  the treatment system  began
 pumping  and  treating  ground water  using
 granulated  activated  carbon to remove  VOC
 contamination,  followed  by  discharging the
 treated ground  water  under permit to Adobe
creek.  This ROD provides a final  remedy to
restore ground water to its beneficial use. The
primary contaminants  of concern affecting the
ground water are VOCs.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
installing  additional extraction  wells onsite;
continuing pumping and treatment of ground
water using the existing granulated activated
carbon  adsorption  system,  followed  by
discharging the treated water onsite to surface
water, or discharging the extracted ground water
offsite with or without treatment to a POTW;
disposing  of any spent carbon offsite;  and
ground water monitoring. The estimated present
worth cost for this remedial action ranges from
$2,100,000  to  $2,200,000 depending  on  the
treatment  selected, which includes  an annual
estimated  O&M cost of $169,000 for  15 to 20
years.

                                     June 26,1991
 SITE HISTORY/DESCRIPTION:

The 550-acre South  Bay  Asbestos  Area  site
consists of a ring levee  in  Alviso,  San Jose,
California.   Land  use in the area  is  mixed
residential, commercial, light  industrial,  and
agricultural. A 300-acre wetlands area is located
adjacent to the site and is partially covered by
the levee. The ring levee was constructed by the
City of San  Jose as  an emergency measure
during a flood in March 1983, but a number of
subsequent EPA investigations determined  that
the levee  soil was comprised of 40 percent
asbestos.  In 1986 and  1987, EPA conducted
several emergency response actions  to reduce
asbestos exposure around the site including the
removal of an asbestos pile, paving and covering
local roads and lots, and spraying the levee with
a  dust-suppressing  polymer.   A 1988 ROD
provided for installation of a vegetated soil cover
over the  levee.    A  subsequent  1989 ROD
addressed the remediation of portions of the site
not previously  addressed and provided  for
paving of  contaminated truck yards, monthly
wet sweeping of  streets,  removal  of asbestos
waste debris, cover  requirements,  inspections,
deed   restrictions   on  landfills,   and   site
maintenance and monitoring. This ROD amends
the 1988 ROD for the asbestos-contaminated soil
in the  ring levee and  surrounding area.  The
primary contaminant of concern affecting the soil
is asbestos, an inorganic.

SELECTED REMEDIAL ACTION:
The selected amended remedial action for this
site includes excavating  and disposing offsite
25,000  cubic  yards of asbestos-contaminated
levee soil; restoring any wetlands areas located
under the levee, or which were disturbed by the
excavation; and conducting soil sampling.  The
estimated present worth cost for this remedial
action is $2,100,000.  There are no O&M costs
associated with this remedial action.

PERFORMANCE STANDARDS OR GOALS:

The  chemical-specific  soil clean-up goal for
asbestos is based on health-based criteria, and is
1 area percent.

                                    March 22,1991
 SITE HISTORY/DESCRIPTION:

 The Spectra-Physics site  is composed of two
 Superfund sites:  the Spectra-Physics site, a laser
 and related components manufacturing facility,
 and  the  Teledyne   Semiconductor   site,  a
 semiconductor manufacturing facility, as well as
 offsite  areas  associated with a contaminated
 ground water  plume  in  Mountain  View,
 California.    Land   use  in  the  area   is
 predominantly commercial and industrial.  The
 site is bordered by Permanente Creek to the west
 and a  landfill dewatering  trench to the north.
 Prior to the construction  of public water and
 sewer connections in 1984, ground water use in
 the area included private water supply wells for
 homes and agriculture.  Many  of these wells
 have been abandoned,  and  only a few currently
 are in use.   Since 1963,  Spectra-Physics has
 manufactured lasers and associated components
 onsite, and has used VOCs including TCE as
 part   of   the   manufacturing   processes.
 Wastewater and  rinse water  were  discharged
 through  five below-grade  sumps  into the
 sanitary water system.  Since 1962, Teledyne
 Semiconductor,   Inc.,   has  operated   a
 semiconductor manufacturing facility onsite.
 Below-grade  sumps  were   used   for  acid
 neutralization  and  waste   TCE  collection.
 Furthermore, an underground storage tank (Tank
 A) was used for storing waste solvents. In 1980,
 all underground solvent handling activities were
 discontinued  and all  chemicals are currently
 stored above ground.  From 1982 to 1984, State
 investigations identified the  release of VOCs
 from solvent tanks into onsite soil at both areas.
 Spectra-Physics and Teledyne have together and
 separately implemented interim  actions onsite.
 In 1987, Spectra-Physics excavated and removed
 all  but one  of   the  sumps  and  6 feet of
contaminated soil from the facility area,  and
 installed a soil vapor  extraction system as an
interim removal action to reduce VOCs in soil.
Teledyne excavated and removed Tank A and
the surrounding contaminated soil, and installed
ground water extraction systems on and around
the   site   to  remove   VOCs  present   in
concentrations above specified levels followed by
discharge of the extracted water to the sanitary
sewer  system.     This   ROD   addresses
contamination of the ground water aquifers and
onsite soil.    The  primary contaminants  of
concern affecting the soil and ground water are
VOCs including PCE, TCE, and toluene.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
expanding the  existing  soil vapor  extraction
system at the Spectra-Physics area  including
treatment of off-gases using granular activated
carbon; ground water pumping and treatment at
both  the Teledyne and  Spectra-Physics areas
using air stripping, followed by  vapor phase
carbon to control air emissions, if the air levels
exceed  permitted  standards,  followed  by
discharging  the  treated  water into  an onsite
storm drain; continuing operation of the existing
ground water extraction systems at the offsite
Mountain View Area, with a contingency  for
adding additional air stripping capacity prior to
discharge into the city sewer system; and soil
and ground  water monitoring.  The  estimated
present worth cost for the Spectra-Physics area is
$2,729,595, which includes an annual O&M cost
of $188,600.  The estimated present worth cost
for the Teledyne  area  is $2,000,000,  which
includes an annual O&M cost of $86,000 for 30
years.  The  estimated present  worth cost  for
monitoring the offsite Mountain View Area is
$10,496,757, which includes an annual O&M cost
of $720,739 for 30 years.  The estimated total
present work cost  for this remedial action is
$18,226,352, which includes an annual O&M cost
of $909,425 for 30 years.

                                     June 28,1991
 SITE HISTORY/DESCRIPTION:
The 1.5-acre Synertek (Building #1) site is a
former semiconductor products manufacturing
facility  in  Santa Clara,  Santa  Clara  County,
California.   The major site  feature is a 24,000-
square-foot building (Building #1).   The site is
composed of both onsite and offsite components.
The onsite component includes the area within
the Synertek property boundaries surrounding
Building #1, and the offsite component includes
the area contaminated by a ground water plume
that has migrated north  past  the property
boundaries and into the adjacent industrial park.
The surrounding   area  is  zoned  for  light
industrial manufacturing.  The site overlies three
shallow aquifer zones, and a deep aquifer zone
that provides  up   to  50%  of  the  municipal
drinking water for the  Santa  Clara  Valley
residences.    It is suspected that  hydraulic
separation among shallow aquifers is imperfect
owing to the discontinuous nature of sediment
types.  Municipal water supply wells perforate
the aquifer  zones  nearby.   Historical ground
water  use   in  the  area  includes   private
water-supply wells for homes and  agriculture
prior  to the  construction  of  public  water
connections and municipal water supply wells.
The location of one agricultural well still remains
unknown and is still under investigation. The
Synertek  site  manufactured   semiconductor
products from 1978 to 1985.  During this period
Synertek  constructed   and   utilized   two
underground tank  systems to store chemicals
and  solvents  used   in  semiconductor
manufacturing processes,  and an underground
concrete vault was constructed for process water
neutralization. In 1982, after Synertek submitted
a Facility Questionnaire to the State describing
their  underground   neutralization   systems,
sumps, and tanks, the State initiated further site
studies to characterize subsurface pollution. The
 State determined  that  accidental  release of
 chemicals leaking  from the two underground
 tank  systems  was a source of onsite ground
 water and soil contamination. In 1985, the State
 required the excavation and offsite removal of
 the solvent and neutralization tanks. In addition,
 onsite ground water pumping and  treatment
 using an air stripping tower began in 1987. A
 well   search   for  abandoned   potentially
 contaminated agricultural wells was conducted
 in 1986 and one well is still unaccounted for.
 This ROD addresses only contaminated ground
 water since the contaminated soil and structures
 were  removed  previously.    The primary
 contaminants of concern affecting  the ground
 water are VOCs including  TCE, vinyl chloride,
 1,1-DCE, cis-l,2-DCE, TCA, and 1,1-DCA.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
continuing operation of the existing ground
water  extraction  and air stripping treatment
system; discharging the treated effluent to an
onsite storm drain; controlling air emissions by
carbon adsorption, if emissions exceed  levels
currently permitted by the Bay Area Air Quality
Management District  (BAAQMD); conducting a
pilot injection study to evaluate if the reinjection
of treated water would enhance the removal of
pollutants, speed  ground water cleanup, and
reduce ground water discharge to the surface;
conducting potential  conduit investigations  to
locate  and  seal  the  remaining  abandoned
agricultural well that is believed to exist close to
the plume; monitoring  ground  water;  and
implementing  institutional controls including
deed and  well use restrictions. The estimated
present worth cost for this remedial  action  is
$895,000, which includes an annual O&M cost of
$61,000.

 drinking water supply, but the State considers
 several of the aquifers to be potential drinking
 water sources. The 1-acre TRW portion of  the
 site has  changed hands several times from 1968
 to present; however, from 1974 to 1986, TRW
 used  its  portion  of  the  study  area  for
 manufacturing semiconductors using solvents,
 metals, and acids.  These substances also were
 used  in  semiconductor  manufacturing  at  the
 AMD and TRW  sites from 1969 to the present
 and from 1964 to the present, respectively. As a
 result   of   responses  to  an   information
 questionnaire regarding an underground tanks
 investigation  at  the  TRW site, a number of
 investigations  were  conducted  that revealed
 extensive  contamination  of onsite  soil and
 ground   water.    Leakage   from  the  acid
 neutralization system at the AMD and leakage
 from an  underground waste solvent storage tank
at the Signetics  site  resulted in a number of
investigations  that   also  revealed  extensive
contamination of onsite soil and ground water at
 both  of  these sites.   Several  initial remedial
 measures have been conducted at the TRW OU.
 From  1983  to  1984,  an  underground  waste
 solvent storage tank and 120 cubic yards of
 onsite contaminated soil were removed.  From
 1984 to present, ground water was pumped and
 treated using air stripping, followed by  onsite
 discharge to surface  water.   Several  initial
 remedial measures also have been conducted at
 the  AMD  OU.   In  1983  and  1984,  acid
 neutralization sumps and about 217 cubic yards
 of contaminated soil were removed. From 1984
 to  1988,  remediation  of  ground  water was
 implemented  using   extraction   wells  and
 dewatering  sumps.   Several  initial  remedial
 measures also were conducted at the Signetics
 OU.  From 1982 to present,  ground water  has
 been pumped from various  site  locations and
 treated  using   air  stripping  and  carbon
 adsorption, followed by air stripping to control
 off-gases and reuse  of the  treated water  in
 industrial processes. Contaminated soil has been
 removed from three separate locations, including
 4,720 cubic yards of soil from a waste solvent
 storage tank area in 1983.  In 1989, three vapor
 extraction  wells  were   installed  to  treat
 contaminated soil.   In addition, two  ground
 water  extraction  systems pump  contaminated
 ground water from the 100-acre offsite plume.
 The extracted water is treated at a neighboring
 AMD facility using air stripping, followed by
 liquid phase granular activated  carbon polisher
 and onsite discharge to surface water or reuse by
 the facility.  This  ROD collectively addresses
 final remediation of soil and ground water in the
 four separate OUs  within the study area.  The
 primary contaminants  of concern affecting  the
ground water are VOCs including PCE and TCE;
and other organics.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
separate remedies for the four different OUs of
the study area.  The remedy for the TRW OU
includes  continuing   onsite   pumping  and
treatment of ground water using air stripping,
followed by onsite discharge of treated water to
surface water.  The remedy for the AMD OU
includes excavating  37 cubic yards  of onsite
contaminated   soil,   followed   by   offsite
incineration and/or disposal, and backfilling the
excavation with clean soil; and continuing onsite
pumping and treatment of ground water using
air stripping and carbon adsorption of off-gases,
followed  by reuse of the treated water.  The
remedy for the Signetics OU includes expanding
the onsite soil  vapor  extraction system;  and
continuing onsite pumping and treatment of
ground water using air stripping, followed by
aqueous-phase carbon  polishing, reuse of  the
treated water, and vapor-phase carbon treatment
of the effluent air stream.  The remedy for  the
offsite ground water OU includes continuing and
expanding the pumping and treatment system
for  contaminated  ground water  using  air
stripping and aqueous-phase carbon adsorption,
followed by reuse of the treated water or onsite
discharge  to   surface  water,  and  offsite
regeneration of spent carbon. Each OU also will
involve continuing  ground water monitoring,
and   implementing   institutional  controls
including  deed  and  ground  water  use
restrictions.   The estimated present worth  cost
for the remedial action for all OUs is $11,900,000,
which includes  an  estimated  O&M cost of
$225,000 for the AMD OU; $236,000 for  the

                                    March 22,1991
 SITE HISTORY/DESCRIPTION:

 The Teledyne Semiconductor site is composed of
 two   Superfund   sites:   the  Teledyne
 Semiconductor   site,  a   semiconductor
 manufacturing facility, and  the Spectra-Physics
 site,   a  laser   and   related  components
 manufacturing facility,  as well as offsite areas
 associated with a contaminated ground water
 plume in Mountain View, California. Land use
 in the area  is predominantly commercial and
 industrial. The site is bordered by Permanente
 Creek to the west and  the City of Mountain
 View landfill dewatering trench to the north.
 Since the construction of public water and sewer
 connections  in 1984, most private  wells have
 been  abandoned; however, eight private wells
 are currently operational  for  residential  and
 agricultural   uses.    Since  1962,  Teledyne
 Semiconductor,  Inc.,  has  operated  a semi-
 conductor manufacturing facility onsite. From
 1962 to 1980, the facility used two 1,400-gallon
 underground sumps for acid neutralization and
 waste TCE collection, and a 2,000-gallon waste
 solvent tank  (Tank A) for collection and disposal
 of liquid chemical wastes onsite.  In 1980, all
 underground solvent handling activities were
 discontinued and  waste holding and disposal
 facilities  were   moved   above   ground.
 Spectra-Physics, Inc., has manufactured lasers
 and associated components onsite since  1963,
 and has used VOCs including TCE as part of the
 manufacturing processes. Wastewater and rinse
 water were discharged through five below-grade
 sumps into  the sanitary water system.  From
 1982 to 1984, State investigations identified the
 release of VOCs from solvent  tanks into onsite
 soil at both areas. Teledyne and Spectra-Physics
 have  together  and  separately  implemented
 interim actions onsite.  Teledyne excavated and
 removed  Tank   A  and  the  surrounding
contaminated soil, and in 1986, installed ground
water extraction systems on and around the site
 to remove VOCs present in concentrations above
 specified levels and discharge extracted water to
 the   sanitary   sewer  system.     In   1987,
 Spectra-Physics excavated and removed  all but
 one of the sumps and six feet of contaminated
 soil from the facility area, and installed a soil
 vapor extraction system as an interim removal
 action to reduce VOCs  in  soil.   This ROD
 addresses contamination of the ground water
 aquifers   and   onsite  soil.     The  primary
 contaminants of concern affecting the soil and
 ground  water  are VOCs including PCE, TCE,
 toluene, and xylenes.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 expanding the existing soil  vapor  extraction
 system at the  Spectra-Physics area  including
 treatment of off-gases  using granular activated
 carbon to control air emissions; ground water
 pumping  and  treatment at both  the  Teledyne
 and Spectra-Physics areas using  air  stripping,
 followed by vapor phase carbon  to control air
 emissions, followed  by discharging the treated
 water into an onsite  storm  drain; continuing
 operation of the existing ground water extraction
 systems at the offsite Mountain View Area, with
 a contingency  for adding additional  extraction
 wells  and treating the extracted water using air
 stripping prior to discharge into the city POTW;
 and   conducting  soil  and  ground  water
 monitoring.  The estimated present worth  cost
 for this remedial action at only the Teledyne area
 is  $2,000,000, which includes an annual O&M
 cost of $86,000 for  30 years.  The  estimated
 present worth cost for the Spectra-Physics area is
 $2,729,595, which includes an  annual O&M cost
 of $188,600.  The estimated present worth  cost
 for monitoring the offsite Mountain View Area
 is $10,496,757, which includes an annual O&M
cost of $720,739 for 30 years. The estimated total
present  cost  for   this remedial  action  is
$18,226,352, which includes an annual O&M cost
of $909,425 for 30 years.

                        VALLEY WOOD  PRESERVING, CA
                                  September 27,1991
 SITE HISTORY/DESCRIPTION:

 The 14.4-acre Valley Wood Preserving (VWP)
 site is  a former wood preserving facility in
 Turlock, Stanilaus County, California. Land use
 in  the area is predominantly agricultural, and
 one residence  is  located  onsite.   There are
 subsurface irrigation drains at the site, which
 eventually discharge to the San Joaquin River
 about 12 miles west of the site.  From 1973 to
 1979, VWP used a solution of chromated-copper
 arsenate (CCA) to preserve lumber onsite. Wood
 preserving chemicals were  mixed  and stored
 onsite  in three above-ground  storage tanks.
 After treatment, the wood was allowed to drip
 dry on  paved and unpaved areas.   Chemical
 spills, leaking tanks, improper onsite disposal
 practices, and  chemical  drippings  from the
 treated   lumber   are  known   sources   of
 contamination.   In 1979, State investigations
 identified   metals   including  arsenic   and
 chromium  in an onsite storage pond, holding
 tanks, onsite and  offsite soil,  and  the onsite
 underlying  shallow  aquifer.  In  1989,  EPA
 investigations identified low levels of chromium
 contamination in  several domestic wells, and
 required VWP to install an interim ground water
 extraction and electrochemical treatment system
 to help contain the migration of contamination.
 EPA also required VWP to design a plan for the
 development of an alternative water supply for
 any affected residences.   VWP also installed
 three deep  ground  water  wells to  serve  as
domestic water supplies.  This ROD provides a
final remedy for contaminated soil and ground
water.   The primary contaminants  of concern
affecting the soil and ground water are metals
including arsenic and chromium.

 SELECTED REMEDIAL ACTION:
The selected remedial action for this site includes
excavating approximately 15,000 cubic yards of
contaminated surface and subsurface soil;
 treating  the  soil  using cement-based fixation;
 backfilling excavated areas with treated soil that
 meets State criteria, maintaining stabilized soil
 mass onsite to prevent future exposure; placing
 treated soil  that exceeds State criteria in lined
 cells onsite; collecting, handling, and disposing
 of  leachate;   pumping  and  treatment  of
 contaminated   ground   water  using
 electrochemical treatment to reduce hexavalent
 chromium to its trivalent form,  followed by
 treating the residual using alumina adsorption to
 remove  any  residual  arsenic;  disposing of
 ground  water  onsite  by  infiltration   and
 evaporation at one or more percolation ponds, or
 by  underground  injection  through  subsurface
 injection wells; disposing  of  sludge generated
 during the treatment process offsite; conducting
 soil,  ground water,  surface  water, and  air
 monitoring;   and  implementing  institutional
 controls  possibly including deed  restrictions,
 The estimated  present worth cost for  this
 remedial action is $3,850,000, which includes an
 annual O&M cost of $224,000.

 PERFORMANCE STANDARDS OR GOALS:

 Soil excavation clean-up standards are based on
 an excess cancer risk level of 10~6 for surface soil
 and levels protective  of ground water  from
 contaminated  leachate for  subsurface  soil.
 Ground water clean-up standards are based on
 State   levels  and   potential  health   risks.
 Chemical-specific  soil goals include  arsenic
 2 mg/kg (risk-based) and hexavalent chromium
4 mg/kg (risk-based) for surface soil; and arsenic
5 ug/kg and hexavalent chromium 5 ug/kg for
subsurface soil.  State criteria require  a  liner
below  soil containing arsenic and  chromium
concentrations greater than  500 mg/kg and
below  soil  exhibiting leachable arsenic and
chromium at 5  ug/1.   Ground water clean-up
goals include arsenic 16 ug/1 (health-based) and
chromium 50 ug/I (State).

                                 September 11,1991
SITE HISTORY/DESCRIPTION:

The 13.7-acre  Van Waters & Rogers site is a
commercial  chemical storage,  handling, and
distribution facility in San Jose, California. Land
use in the area is predominantly commercial and
industrial.   Nearby  surface  drainage  features
include Coyote Creek, approximately 1,200 feet
to  the  east,  and   the  Guadalupe   River,
approximately  6,000  feet to  the  west, that
discharge to San Francisco Bay 9 miles  to the
north.  Since  1976, Van Waters &  Rogers has
used the site for bulk chemical transfers; storage
in drums and underground tanks; chemical
blending, packaging,  and  distribution; and
rinsing  of containers.   Surface features  from
which  releases of  organic  chemicals   have
occurred  are   above-ground  storage   tanks,
rail-mounted   tank   cars,   drum  fillers,
underground  storage  tank   (UST) fill   pipe
manifolds, and a hazardous waste storage area.
Subsurface features include 37 USTs; subsurface
product  transfer  piping; and the  subsurface
storm drain system, which eventually discharges
to the Guadalupe River.  Fourteen USTs are not
in service and are currently  empty. With the
exception of one tank used to store diesel fuel,
all  USTs have been used  to store  various
industrial chemicals including PCE, toluene, and
xylenes.  During a survey of regional hazardous
waste  facilities in 1982, the State identified
VOCs, selected aliphatic hydrocarbons, aromatic
hydrocarbons,  ketones, glycols, and alcohols in
onsite soil and ground water.  Potential sources
of contamination  include a 1977  accidental
release   of   PCE   from  an  above-ground
12,000-gallon   tank at the loading  dock and
various leaks from USTs and associated piping.
Van Waters &  Rogers began an interim ground
water remediation program in 1986 that involves
ground water extraction and treatment using air
stripping with onsite discharge  to  the  storm
drain. This ROD provides a final remedy for
onsite contaminated  soil,  debris,  and ground
water.  The primary contaminants of concern
affecting the soil, debris, and ground water are
VOCs including PCE  and TCE.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
treating approximately 8,100 cubic yards of soil
"hot spots" containing more than 10 mg/kg of
one or more of PCE, TCA, and TCE using in-situ
vapor extraction;  temporarily  capping 46,000
cubic yards  of soil  containing greater  than
1 mg/kg total VOCs, including areas containing
USTs  until   tank  removal  can  take place;
removing USTs at a later date and  investigating
adjacent  soil;  expanding  the  existing upper
aquifer ground water pumping and treatment
system by adding an  air stripping unit and
converting   existing   monitoring   wells   to
extraction wells, wherever possible; treating the
off-gases from the  new  air  stripping unit;
treating the  lower aquifer by  either granular
activated carbon or air stripping; discharging the
treated ground water onsite to the storm drain
system; monitoring soil and ground water; and
implementing  institutional controls including
deed restrictions.  The estimated present worth
cost for this remedial action is $4,997,000, which
includes  a  net present value  O&M  cost  of
$4,374,000.

PERFORMANCE STANDARDS OR GOALS:

Clean-up goals for soil are intended to minimize
contaminant   migration  to   ground   water.
Chemical-specific initial soil goals  for PCE and
TCE are  10  mg/kg.   Final soil goals will be
1 mg/kg for  total  VOCs.  Chemical-specific
ground water clean-up goals are based on State
and Federal MCLs and risk levels, and include
PCE 5 ug/1 (MCL) and TCE 5 ug/1 (MCL).

                                 September 19,1991
 SITE HISTORY/DESCRIPTION:

 The  American  Lake   Gardens  (McChord
 AFB-Area D) site is an active U.S. Air Force Base
 located  at McChord  Air Force Base,  Pierce
 County, Washington.  The site consists of two
 areas, Area D and American Lake Garden Tract
 (ALGT).   Area D  is located entirely on-base.
 Area D  activities  include  Air  Force  Base
 administration,  flight   operations   support
 functions, and housing and recreation facilities.
 Approximately 2,384 people reside in the Area D
 housing  facilities.    ALGT  is  an  off-base
 commercial   and  residential  area   with
 approximately  3,431  residents  and various
 businesses.  Hydrogeologic units exist  onsite
 including a series of confined and unconfined
 aquifers  that  appear  to  be  hydraulically
 connected.  Various surface water bodies exist
 near  the site and  are principally ground
 water-fed.  From the mid-1940's to the present,
 no known industrial activities have occurred in
 the ALGT area; however, seven waste disposal
 sites have operated within the Area D portion of
 the site.   In  1981,  the  Air Force initiated a
 multi-phase program to  identify past disposal
 sites and contaminants and to  eliminate public
 health  risks.     Concurrent   with   DOD
 investigations, EPA discovered  TCE in ground
 water monitoring wells installed at the ALGT,
 and in 1984, concluded that waste disposal sites
 in Area D were the likely source of ground
 water contamination. Modeling studies indicate
 that most of the soil contamination by VOCs has
 moved into the ground water, and that DNAPLs
 may continue  to act as a secondary source of
ground water contamination. In 1986, the Air
 Force provided an alternate water source to
 residents of ALGT, and subsequently connected
80% of the residences to a public water supply.
This ROD addresses remediation of the
 contaminated onsite and  offsite ground water
 plume,  as  a  final  remedy.   The  primary
 contaminants of concern  affecting the ground
 water are VOCs including benzene, PCE, TCE,
 toluene, and xylenes; other organics; and metals
 including arsenic, chromium, and lead.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 pumping and treating both the onsite and offsite
 ground  water  contaminant plumes  in  the
 confined aquifer using an  onsite multi-bed
 carbon adsorption treatment facility, followed by
 recharging or irrigating the treated ground water
 onsite; regenerating the spent  carbon offsite;
 monitoring  the  ground  water  contaminant
 plume; and implementing institutional controls
 such as  deed,  ground water,  and land  use
 restrictions.  The estimated present worth cost
 for this remedial action ranges from $4,445,000 to
 $6,949,000, for interest  rates of 10%  and 4%
 respectively,  which includes an annual O&M
 cost of $341,000 for years  0-2 and $318,000 for
 years 3-30.

 PERFORMANCE STANDARDS OR GOALS:

 Ground   water   will  be  restored  to  levels
 consistent  with  State  and Federal  MCLs.
 Chemical-specific goals for ground water include

                   BANGOR NAVAL SUBMARINE BASE, WA
                                 September 19,1991
 SITE HISTORY/DESCRIPTION:

 The Bangor Naval Submarine Base (SUBASE) is
 a  former  munitions  handling,  storage,  and
 processing facility in Kitsap County, Washington.
 Land surrounding the  SUBASE  is generally
 undeveloped and supports limited residential
 use.  The site overlies the surficial shallow
 aquifer  and  deeper  aquifers,  which are the
 principal water supplies for SUBASE Bangor and
 surrounding   communities.     Demilitarizing
 (demil)  operations were conducted from 1940
 until  1978, and included collecting condensate
 and solid  explosive  within a  holding  tank,
 followed by removal of the solid material from
 the wastewater before final discharge. Site F, a
 wastewater lagoon, was used between 1960 and
 1971  to dispose of final  wastewater solution.
 Periodically, the lagoon was allowed to drain.
 Waste materials present in surficial sediment of
 the lagoon were burned off in place with waste
 oils, or  transported  to  the onsite  ordnance
 burning area for thermal destruction. Between
 1972 and  1980, wastewater  was collected into
 55-gallon barrels and delivered  to the SUBASE
 liquid-waste   incinerator.     Several   onsite
 investigations of the distribution and transport of
 waste constituents at Site F have occurred since
 1971.  Based on data collected, it was confirmed
 that soil in the lagoon area is contaminated by
 ordnance constituents. In 1972,500 cubic feet of
 soil was excavated from the top several feet of
 the lagoon  and  transported  to the  onsite
ordnance burning area for burning. In 1980, the
lagoon was filled in and covered with a low
permeability  asphalt  cover    Ground  water
quality data collected  at Site F  during prior
studies indicated that only the Shallow Aquifer
has been impacted by Site F. This ROD is an
interim remedial action addressing ground water
contamination at Site F as operable unit 2 (OU2).
 The intent of this  remedy is to contain  the
 contaminated ground  water plume.  A future
 ROD will address final remediation of both soil
 and ground water. The primary contaminants of
 concern affecting the ground water are organics
 including RDX; 2,4,6-TNT; 2,4-DNT; 2,6-DNT;
 1,3,5-TNB; 1,3-DNB; N-nitrate; and nitrobenzene.

 SELECTED REMEDIAL ACTION:

 The selected remedial action for this site includes
 pumping and treatment  of ground water from
 the  Shallow  Aquifer  using  UV-oxidation;
 reinjecting the treated ground  water onsite into
 the Shallow  Aquifer,  or infiltrating it onsite
 using  a recharge  basin; monitoring  ground
 water;  and providing design  information, as
 applicable,  for   the  final remedy.    If the
 UV-oxidation  process  cannot   achieve  the
 specified performance  standards due to either
 technological or economic concerns, then carbon
 adsorption   will  be   coupled  with   the
 UV-oxidation system to complete the treatment
 process prior to disposal. The estimated present
 worth cost for this remedial action is $2,515,000,
 which includes an O&M cost of $1,300,000 over
 2 years.

 PERFORMANCE STANDARDS OR GOALS:

 Chemical-specific ground water clean-up goals
 are based on Model Toxic Control Act (MTCA)
 clean-up standards and  include RDX 5 ug/1;
 2,4,6-TNT 3 ug/1; 2,4-DNT 0.1 ug/1; 2,6-DNT
 0.1 ug/1; 1,3,5-TNB 0.8 ug/1; 1,3-DNB 2 ug/1;
N-nitrate 10,000 ug/1; and nitrobenzene 8 ug/1.

      BUNKER HILL MINING AND METALLURGICAL COMPLEX, ID
                                    August 30,1991
SITE HISTORY/DESCRIPTION.

The Bunker Hill  Mining  and  Metallurgical
Complex site is a 21-square-mile area centered
around an inactive  industrial  mining  and
smelting site, and includes the Cities of Kellogg,
Smelterville, Wardner, Pinehurst, and Page, in
Shoshone County, Idaho. The inactive industrial
complex includes the Bunker Hill mine and mill,
a lead smelter, a zinc smelter, and a phosphoric
acid fertilizer plant, all totaling several hundred
acres.  Furthermore, the site includes the South
Fork of the Coeur  d'Alene River, an alluvial
floodplain  bordered  by  mountains,  numerous
valleys and gulches, and vegetated residential
areas.  In 1886, the first mill for processing lead
and silver ore was constructed  at  the  site.
Operations were expanded in later years  with
the addition of a lead smelter; a blast furnace;
and electrolytic zinc, sulfuric  acid, phosphoric
acid, and  fertilizer plants.  Onsite operational
and  disposal  practices  have  caused   the
deposition of hazardous substances (e.g., metals)
throughout the valley via airborne particulate
deposition,  alluvial  deposition  of  tailings
dumped in the river, and migration from onsite
sources.  Initially, most of the solid and liquid
residue from the complex was discharged into
the  river.   When  the  river flooded,  these
materials were deposited onto the valley floor,
and have  leached into onsite  soil and ground
water.  Although some of the industrial  wastes
have been removed and disposed  of  offsite,
thousands of tons of sludge, tailings, flue dust,
and  other  wastes   still   remain   onsite.
Contamination at the site is a result of tailings
deposition  in   the  floodplain,  and  airborne
deposition  from  smelter  and  mill  complex
emissions.  A fire in 1973 severely reduced air
pollution control capacity at the lead smelter. A
1974  public  health  study   and  concurrent
epidemiologic and environmental investigations
concluded that atmospheric emissions of
particulate lead from the active smelter were the
primary sources of elevated blood lead levels in
local children.  In 1977,  two tall stacks were
added  to  disperse  contaminants  from  the
complex. The complex ceased smelter operations
in 1981,  but  continued  limited  mining and
milling operations from 1988 to early 1991.  In
1989, EPA began a removal program to excavate
lead-contaminated soil from affected residential
properties.   Federal  and State agencies have
designated a 21-square-mile study area, which
has been divided into  populated areas and
non-populated areas for remediation.  This ROD
addresses contaminated residential soil  within
the populated areas of the site, and includes four
incorporated   communities  and   three
unincorporated residential areas as operable unit
1. The nonpopulated areas of the site as well as
all other  contaminated media in the populated
areas  (e.g.,  house  dust,  and  commercial
properties) will be addressed in a  future ROD.
The primary contaminants of concern affecting
residential area soil are metals including arsenic
and lead.

SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
soil sampling; excavating contaminated soil and
sod   exceeding   1,000 mg/kg lead   on
approximately  1,800 residential properties, and
replacing it with clean soil and sod; disposing of
the contaminated soil  and sod at  an  onsite
repository; capping  the repository;  placing a
visual marker if lead levels  in  soil exceed
1,000 mg/kg below  the depth  of excavation;
revegetating the  area; conducting  long-term
environmental  monitoring; and implementing
institutional controls including deed and land
use restrictions.  The estimated present worth
cost for this remedial action is $40,600,000, which
includes an annual O&M cost of $460,000 for 30
years.

 NORTHWEST TRANSFORMER - MISSION POLE (AMENDMENT), WA
                                September 30,1991
SITE HISTORY/DESCRIPTION:

The 1.6-acre Northwest Transformer - Mission
Pole site,  a former transformer  storage and
salvage facility, is 2 miles south of Everson in
Whatcom  County,  Washington.   The site is
bordered by low-density residential areas to the
north  and  east,  and farmland to the south.
Storage and salvage operations were conducted
in an  onsite  barn  where PCB-contaminated
dielectric   fluid   was   drained   from   the
transformers prior to dismantling.  Transformer
casings and associated parts  were incinerated
onsite, and some of the recovered oil was burned
to heat the barn.   Spills and  leakages  of
PCB-laden  oil  onto  the ground  occurred
frequently.   Additionally, oil was  dumped
directly  into a seepage pit  onsite,  and  has
contaminated soil and  possibly ground water.
EPA studies from 1977 to 1985 identified PCS
concentrations as high as 38,000 mg/kg in onsite
media.  In 1985, EPA removed 1,400 cubic yards
of PCB-contaminated  soil and  debris, 6,660
gallons of PCB-contaminated liquids, and several
contaminated transformer casings. In addition,
EPA initiated  a  ground  water  monitoring
program and imposed site access restrictions. In
1987, sufficient PCB contamination was identified
in the soil to warrant further site remediation. A
1989 ROD  addressed  remediation   through
excavation,  consolidation, and onsite treatment
using in-situ vitrification. This ROD amends the
1989 ROD and provides a change in the remedy
for  soil  due to excessive  cost.  The  primary
contaminant of concern affecting the soil is PCB,
an organic.

SELECTED REMEDIAL ACTION:

The amended  remedial action for  this ROD
includes incinerating approximately 70 cubic
yards of soil contaminated with PCBs at levels
greater than or equal to 50 mg/kg at a TSCA-
approved facility, landfilling approximately 1,500
cubic yards of soil contaminated with PCBs at
levels greater than or equal to 1 mg/kg and less
than 50 mg/kg off site at  a  TSCA-approved
facility; demolishing the barn and disposing of
the debris off site; testing the soil and concrete
within the barn; placing a  soil cover over the
entire  site;  and  implementing  institutional
controls, if necessary. The estimated capital cost
for this amended remedial  action ranges  from
$1,400,000 to  $4,000,000  depending  on  the
amount of soil removed. O&M costs were not
provided.

PERFORMANCE STANDARDS OR GOALS:

Chemical-specific soil clean-up goals are based
on the Washington State Model Control Act and
include PCBs 1 mg/kg.

INSTITUTIONAL CONTROLS:

If  complete removal of  soil  with  PCB levels
>1 mg/kg  cannot  be   demonstrated  and
hazardous materials remain onsite, institutional
controls will be implemented.

                                 September 10,1991
SITE HISTORY/DESCRIPTION:

The Union Pacific Railroad Yard site is an active
railyard located in Pocatello, Bannock County,
Idaho.    Land  use  in  the  area  is mixed
commercial  and  light industrial,  with some
residential areas.  Site features include sludge
pits along the northwestern edge of the site, and
Portneuf River, which is located 1,000 feet from
the pit.  Ground water in  the vicinity of the
sludge pit occurs in two distinct water-bearing
deposits, the Upper and Lower Aquifers, which
appear to be hydraulically  connected.  Union
Pacific Railroad (UPRR) began operations around
the turn of the 20th century.  Site operations
have included maintenance and repair  work,
train assembly, and refueling,  which involved
the  use   of  various  fuels, cleaning  agents,
detergents,   and   degreasers,   including
halogenated and non-halogenated hydrocarbon-
based solvents. UPRR constructed a treatment
plant in 1961 to receive industrial  wastewater
and surface   stormwater  run-off   from  the
railyard. Until 1983, sludge  from the treatment
plant's oil/water separator and from a dissolved
air flotation unit was  disposed in the onsite
sludge pit. Currently, the  sludge pit  contains
approximately 2,500 cubic yards of  sludge and
1,700 cubic yards of contaminated soil beneath
the sludge.   In  1983, EPA determined that
seepage from UPRR's sludge pit, and from a
nearby area where an oil tie  treating facility was
located  were contributing  to  Upper  Aquifer
ground water contamination. In 1985, UPRR, the
only identified PRP, conducted  an investigation
of the railroad yard, and the  sludge  pit was
determined to be  the principal  source of onsite
contamination.     This  ROD   addresses
contamination of the Pocatello Sludge Pit located
at  the   UPRR   property.     The   primary
contaminants  of  concern  affecting  the  soil,
sediment,  sludge,  and ground water are VOCs,
other  organics   including  PAHs   and
petroleum-based hydrocarbons (oils), and metals.
SELECTED REMEDIAL ACTION:

The selected remedial action for this site includes
implementing a comprehensive  soil, sediment,
sludge, and ground water sampling effort prior
to remedial activities to determine background
levels  and  to  set final  remediation goals;
excavating to the maximum extent practicable up
to 4,200 cubic yards of visibly-contaminated soil,
sediment, and sludge; testing these media for
compliance  with  land  disposal   restriction
treatment standards, followed by disposal at an
approved offsite landfill; treating soil remaining
beneath  the excavated  area  using  in-situ  soil
flushing  as part of the Upper Aquifer ground
water treatment system, backfilling, grading, and
capping the entire pit boundary; extracting and
treating nonaqucous phase liquid contaminants
from the Upper Aquifer ground  water using an
onsite oil/water separator  and a dissolved air
flotation  unit; discharging  effluent offsite  to a
POTW; placing skimmed oil in an onsite holding
tank for sale to a recycler; disposing of residual
sludge from  ground water  treatment  offsite;
conducting  quarterly sampling and analysis of
ground water to ensure remediation goals are
met; constructing a fence around the sludge pit;
providing advanced  funding for design  and
installation of an alternate water supply system
to be implemented if monitoring indicates that
ground   water  contamination  has  not beeri
adequately   remediated;  monitoring  ground
water, surface water, and air; and implementing
administrative  and   institutional   controls
including deed, land, and ground water  use
restrictions.  The estimated present worth cost
for this  remedial action is $3,797,550, which
includes a present worth O&M cost of $1,657,900
for 30 years.

PERFORMANCE STANDARDS OR GOALS.

Chemical-specific remediation  goals have not
been finalized, with the exception of lead 500
mg/kg  for  soil  and 0.015  mg/1  (MCL) for
ground  water, as a result of incomplete data
regarding   background  concentrations  of
contaminants in soil,  sediment, sludge,  and
ground  water.  Final  clean-up goals  will be
based on background  concentrations,  lowest
practical  quantitation  limits,  ground  water
ARARs   identified   in  the   FS,  or  target
concentration  values,  whichever  is highest.
Health-based clean-up goals include a 10~6 cancer
risk   for  carcinogens  and   an  HI<1  for
non-carcinogens.

                                 September 30,1991
SITE HISTORY/DESCRIPTION:

The 0.94-acre Yakima Plating site is an inactive
nickel-chrome  automobile  bumper  replating
facility in Yakima, Yakima County, Washington.
The site lies  within a mixed light commercial
and residential area, and  there are four schools
within 1 mile of the site. Ground water from the
shallow alluvium aquifer supplies much of the
domestic and irrigation water in the Yakima
Basin, and many residences adjacent to the site
utilize private ground water wells for their water
supply.  Yakima Plating began operations  in
1965  utilizing 20 to 30 above-ground holding
tanks, which were  stored  within the plating
building.  These  tanks were used during the
electroplating operation cleaning,  plating, and
rinsing processes. Rinse water and spent plating
tank solutions were disposed of in a floor drain
within the plating room.  The floor  drain was
connected to an underground sedimentation tank
and  drain   field  line  that   collected   the
sedimentation tank overflow and distributed the
wastewater to subsurface  soil. The wastewater
system  operated  from  1965  until  plating
operations ceased in 1990. Site assessments and
investigations conducted by EPA contractors in
1984 and 1990 determined that the sludge and
effluent from  the settling tank were a dangerous
waste  under State  regulations  and  that  the
potential exists  for public exposure to metals
from  contact with contaminated  surface  and
subsurface   soil.     This   ROD   addresses
remediation of contaminated onsite soil, debris,
and  sludge.   The  primary contaminants  of
concern affecting the soil, debris, and sludge are
organics  including  pesticides;  and   metals
including arsenic, chromium, copper, lead, and
nickel.
SELECTED REMEDIAL ACTION.

The selected remedial action for this site includes
removing 1,500 gallons of liquid and 6.5 cubic
yards  of  sludge  currently  in  tanks  and
containers, and treating and disposing of these
materials  at   an offsite  facility;  excavating,
treating, and disposing of contaminated soil at
an   offsite   landfill;  excavating   and
decontaminating underground  tanks using  a
solvent or water-based solution; abandoning the
tanks in place, and covering the tank areas with
clean fill; treating and disposing of any liquids
or sludge generated during the decontamination
process at an offsite facility; and excavating and
disposing of  540 cubic  yards of  soil  and
underground  drain  lines at an  offsite facility;
ground  water monitoring; and  implementing
institutional controls including land and ground
water use restrictions.  The  estimated present
worth cost for this remedial action ranges from
$310,000 to $377,000, depending on the type of
solution used for debris decontamination. There
are no O&M costs associated with this remedial
action.

PERFORMANCE STANDARDS OR GOALS:

Clean-up levels for soil and ground water are set
at the  more  stringent  of Federal  and  State
standards.  Chemical-specific soil remediation
goals include arsenic  20 mg/kg,  chromium
400 mg/kg, lead 50 mg/kg, and DDT 2.9 mg/kg.

INSTITUTIONAL CONTROLS:

Land use and ground water restrictions will be
implemented at the site.

(soil) using in-situ vacuum extraction; treating air
emissions using carbon adsorption or thermal
destruction prior to discharge, if necessary;
further treating soil using biodegradation based
on the results of a treatability study; and

Not No further action since previous investigations
applicable indicated that GW and soil contamination
associated with the site no longer pose a health
threat under current or likely future land use
conditions. However, a comprehensive GW and
air monitoring program will be implemented,
which will include installing additional
monitoring wells and sampling downgradient
residential wells. In addition, sediment and SW
sampling also will be conducted.

Clean-up Goals
Chemical-specific soil clean-up
goals are based on New Jersey
Interim Soil Action Levels and
include 1 mg/kg for total VOCs
and 10 mg/kg for semi-volatiles,
and are designed to mitigate the
threat of GW contamination.

Not specified Closing and capping the unlined landfill area
with a clay or synthetic cap; onsite pumping and
treatment of contaminated GW using an air
stripper, followed by carbon adsorption with
onsite discharge of treated GW to SW;
regenerating spent carbon offsite; and long-term
monitoring of the closed landfill and GW. If the
selected remedy cannot meet the specified
remediation goals, a contingency remedy will be
implemented, which will include a combination
of containment technologies including GW
extraction and treatment, and institutional
controls.


Not No further action because previous interim
applicable remedial activities were adequate to protect
human health and the environment. GW
monitoring at the MKT and MBS locations will
be performed, including expanding the ongoing
water quality monitoring program at the MKT
location, and installing four GW monitoring wells
at the MBS location.
Clean-up Goals
GW will be remediated to
background levels as specified by
State Hazardous Waste
Management Regulations.
Chemical-specific goals include
benzene 0.2 ug/1, PCE 0.03 ug/1.
TCE 0.03 ug/1, chromium 50 ug/1,
and lead 5 ug/1.

                becomes technically impracticable to achieve
                clean-up goals
Soil action levels for saturated and
unsaturated soil and "principal
threat" action levels were
developed based on MCLs, RCRA
toxicity characteristic levels
(TCLP), and health-based criteria.
The target clean-up goal for
surface soil is arsenic 21 mg/kg.
Action levels for unsaturated soil
include benzene 0.009 mg/kg,
PCE 0.051 mg/kg,  TCE 0.017
mg/kg, and arsenic 450 mg/kg.
Action levels for saturated soil
include benzene 0.002 mg/kg,
PCE 0.012 mg/kg,  TCE
0.004 mg/kg, and arsenic
210 ug/kg based on protection of
GW.  Principal threat action levels
include benzene 10 mg/kg, PCE
14 mg/kg, TCE 10 mg/kg, and
arsenic  1,000 mg/kg. GW clean-
up goals are based  on Federal
MCLs, proposed MCLs, a 10"*
excess cancer risk level, and an
HI=1.  Chemical-specific GW
clean-up goals include benzene
0.005 mg/1 (MCL), PCE 0.005
mg/1 (pMCL), TCE 0.005 mg/1
(MCL), and arsenic 0.05 mg/1.  A
State ARAR to remediate GW to
background levels will be waived
because of technical
impracticability.

The selected remedial action for this site includes
continuing the operation of eight existing GW
extraction wells; and treating contaminated GW
onsite using air stripping and carbon adsorption,
followed by discharge of the treated water onsiie
to SW.
Paving the road through the Mine Area or
implementing an appropriate road maintenance
alternative; constructing stream diversions,
sediment trapping dams, and other slope
stabilization  elements; instituting a verification
sampling plan involving SW modeling and SW
and stream bed sampling, as necessary;
conducting a revegetation pilot project, and
implementing revegetation if found to be
technically feasible and cost-effective;
dismantling the mill building with of fall* disposal
along with other debris from the Mine Area; and
implementing institutional controls including deed
and land use restrictions, and site access
restrictions such  as fencing
     clean-up standards are based
on the more stringent of Federal or
State MCLs for drinking water.
Chemical-specific goals for GW
ijichide PCE 5 ug/1 (MCL), and
TCE 5 ug/1 (MCL).
All diversion and drainage
facilities will be designed and
constructed to accommodate the
anticipated volume of precipitation
afld peak flows from surface run-
off in a 25-year, 24-hour storm.
All tailings will be protected from
100-year peak stream flows.
Quantification of risk reduction is
difficult because asbestos from
n/uural and disturbed areas will
continue to enter SW; however, a
verification sampling plan will be
implemented to confirm that  an
appropriate red action in asbestos
transport is achieved.

            DESCRIPTION OF TREATMENT TECHNOLOGIES FOR
                 SOURCE CONTROL AND GROUND WATER
Source Technologies:

Treatment technology for source material are grouped based on the primary functions for which
they are generally used: destruction/detoxification, separation/recovery, immobilization, and
other. The specific technologies listed are those identified in the RODs.

                    I.  DESTRUCTION/DETOXIFICATION


A.     Bioremediation

       Biological treatments use microorganisms to degrade primarily low to moderate levels of
       organic contaminants in aqueous waste streams and soil. Biological treatments include:

              •     In-Situ Bioremediation - uses natural populations or seeded bacteria to
                    biodegradc organic compounds. The biological process may be
                    accelerated by introducing nutrients and oxygen. This process is often
                    used in conjunction with a ground water pumping and reinjection
                    system to circulate nutrients and oxygen through a contaminated aquifer
                    and associated contaminated soil.

              •     Solid/Slurry Phase Bioremediation - involves commingling excavated
                    organic-contaminated soil and sludge with bioactive microorganisms in a
                    mobile batch reactor or an in-ground reactor. Waste is mixed with water
                    to create a slurry composition, and the slurry is mixed to maximize
                    treatment of organic contaminants. Upon completion of the process, the
                    slurry is dewatered and the treated soil is disposed of.

B.     Chemical Destruction/Detoxification

       Chemical destruction/detoxification processes alter the hazardous substances to produce
       a by-product residue that is less hazardous than the original waste and may be easier to
       remove from the waste stream.  Chemical destruction/detoxification processes include:

              •     Chemical Reduction/Oxidation (redox) - a destructive process that
                    changes the chemical nature of the nature of the contaminants.

              •     Dechlorination - is a destruction process in which chlorine is chemically
                    removed from chlorinated organic compounds. This process converts
                    the more toxic compounds into less toxic, more water soluble products.
                    The transformation of contaminants within the soil produces compounds
                    that are more readily removed from the soil.

                  SOURCE CONTROL AND GROUND WATER
                                  (CONTINUED)
C     Thermal Treatment

       Thermal treatments use heat to destroy or detoxify hazardous substances, encompassing
       such technologies as incineration, pyrolysis, and wet air oxidation. Specific incineration
       types include rotary kiln, liquid injection, fluidized-bed, and infrared treatment.
       •      Incineration - is a controlled flame combustion process in which organics are
              destroyed producing carbon dioxide, water, and other compounds.

       •      Pyrolysis - is a decomposition process in which organics are thermally
              decomposed into their individual elements, in an oxygen deficient atmosphere.

       •      Wet Air Oxidation - is a process that involves adding high pressure and
              temperature to a water solution or suspension to destroy organics.

A.     Chemical/Physical Extraction

       Chemical/Physical Extraction is a transfer/separation process in which contaminants are
       dissociated from the matrix either through a chemical or a physical process and are
       dissolved in a liquid or gaseous phase which may require further treatment.
       Chemical/physical extraction processes include:

              •      In-SituSoil Flushing - is an in-situ extraction process that uses a flushing
                     agent, e.g., water to extract contaminants.

              •      In-Situ Vacuum/Soil Vapor Extraction - is an in-situ process that
                     involves extraction of VOCs from soil using a vacuum or forced air. This
                     process is generally used with other technologies since it transfers
                     contaminants from the soil to air and water waste streams.

              •      Soil  Washing - is a physical/chemical separation technology in which
                     excavated soil is washed with fluids to remove contaminants. Soil
                     washing is generally followed by other technologies in a treatment train.

B.     Thermal Desorption

       Thermal Desorption uses heat to extract volatile organics from the matrix and may be
       followed by other treatments to collect and/or destroy contaminants. Thermal
       desorption processes include:

       •      Ex-Situ Thermal Desorption - is a physical transfer process that uses air, heat, and
              mechanical agitation to change volatile organic compounds (VOCs) in soil into a
              gas stream, where the contaminants are then further treated.

       •      In-situ Stream Stripping/Hot Air Stripping - involves the injection of steam or
              hot air into soil to volatilize VOCs. As VOCs rise to the surface they are
              condensed or trapped on activated carbon.


                            III. IMMOBILIZATION

       Immobilization

       The term "immobilization" is used to mean any of the technologies which limit the
       solubility or mobility of contaminants. The term "fixation" has also been used as a
       synonym for immobilization. Technology types which fall within  the realm of
       immobilization include:

              •      Stabilization - involves the addition and mixing of materials that limit the
                     solubility or mobility of the waste constituents even though the physical
                     characteristics of the waste may not be changed.

              •      Solidification/Stabilization - involves the addition and mixing of
                     materials that limit the solubility or mobility of the waste constituents,
                     and results in a monolithic structure.

              •      Sorbent Solidification - involves the addition and mixing of materials that
                     limit the mobility of the waste constituents through the action of
                     sorption,


                                    IV.  OTHER

       In-situ Vitrification (ISV) - is a thermochemical treatment process that destroys,
       removes, or immobilizes hazardous wastes by electrically melting  the waste media (e.g.,
       soil) which upon cooling creates an extremely stable glass-like solid. ISV can be used to
       treat soil and sludge contaminated with radioactive, inorganic, or organic wastes or
       mixtures of these contaminants.

                                  (CONTINUED)
Ground Water Technologies:

Treatment technologies for ground water are grouped based on the categories commonly used in
the waste water treatment industry: chemical/physical treatment biological, and other. The
technologies are listed in their order of appearance in Exhibit 5.

                            I.  CHEMICAL/PHYSICAL

              •      Air Stripping (Desorption) - is a physical process that involves bringing
                     ground water into close contact with air thereby causing VOCs in the
                     liquid phase to transfer to the gas phase. For ground water, this
                     generally is accomplished by injecting water into an air stream. Exhaust
                     air may have to be treated (e.g., using carbon adsorption) to remove
                     VOCs before discharge to the atmosphere.

              •      Carbon Adsorption - is a physicochemical  process that involves using
                     activated carbon as a sorbent to remove primarily soluble organics from
                     air and water. As contaminated ground water contacts activated carbon,
                     organic molecules become physically/chemically attached (i.e.,
                     adsorbed) to the carbon surface. There are two basic types of activated
                     carbon: granular and powdered, based on the size of the carbon
                     particles.

              •      Precipitation - is a physicochemical process that involves transforming a
                     contaminant from solution into a solid phase. Precipitation for ground
                     water remediation is used primarily for the removal of heavy metals
                     using such precipitating chemicals as lime, alum, or iron salts. Chemical
                     precipitation is followed frequently by flocculation to enhance settling of
                     solid particles for subsequent removal by filtration or sedimentation.
                     Physical precipitation, including cooling, heating or altering the solvent
                     concentration, also can be used to alter solubilities and precipitate
                     contaminants.

              •      Granular Activated Carbon - is carbon prepared by heating various types
                     of woods and coal to drive off hydrocarbons but with insufficient air to
                     sustain combustion. The resulting char is activated by exposure to an
                     oxidizing gas at high temperatures. The carbon particles generally are
                     used in carbon adsorption processes (see above).

              •      Filtration - is a physical process that involves forcing contaminated
                     ground water through a porous granular-media filter (e.g., sand,
                     anthracite) to remove suspended particles. Several mechanisms are
                     involved in filtering suspended particles from the ground water,
                     including straining, flocculation, and sedimentation.

      SOURCE CONTROL AND GROUND WATER
                      (CONTINUED)
         Ion Exchange - is a reversible process whereby toxic ions (i.e., anions and
         cations) in solution are exchanged with less harmful, similarly charged
         ions electrostatically attached to a solid synthetic resin material.  The
         toxic ions having a stronger affinity to the resin, will replace the original
         ions that were placed on the resin before treatment. Once the available
         exchange sites on the resin are filled, the resin can be regenerated.

         Sedimentation - is the removal of suspended solids from wastewaters by
         the gravitational settling of particles heavier than water. Sedimentation
         may be used in ground water treatment after biological treatment or
         precipitation/flocculation to remove biomass or precipitants.

         UV Peroxidation - is a chemical oxidation process that uses hydrogen
         peroxide in the presence of a catalyst to generate hydroxyl radicals that
         react with organics and reduced compounds to yield carbon dioxide,
         water, salts, simple organic acids, and/or sulfates thereby reducing the
         toxicity and organic content of wastewaters. The application of
         ultraviolet (UV) light to the waste treatment (photolysis) to
         enhance/induce chemical

         transformations can be used in conjunction with peroxidation. A major
         advantage of UV application is that specific bonds can be targeted by
         selecting the appropriate frequency of the light source.

         Chemical Treatment - involves chemical reduction-oxidation (redox)
         reactions in which the oxidation state of at least one reactant is raised
         while that of another is lowered. Redox reactions can detoxify and
         enhance biodegradability or adsorption (oxidation), or reduce solubility
         (reduction).

         Flocculation - is a chemical/physical process that involves agitating
         chemically treated water to enhance precipitation and  induce
         coagulation. Fine suspended particles formed during precipitation
         collide during gentle mixing, and agglomerate into larger heavier
         particles or floes and settle out. Flocculating agents such as alum, lime,
         iron salts, and organic flocculating agents are added to reduce natural
         repelling surface charges on particles, and physical agitation is used for
         the formation of large floes.

         Activated Alumina - is an adsorption process that is used to remove
         dissolved inorganic constituents such as arsenic, fluoride, and selenium.
         As contaminated ground water contacts activated alumina, inorganics
         become physically/chemically attached (i.e., adsorbed) to the alumina
         surface. Activated alumina is a highly porous, granular form of
         aluminum oxide.

         Aeration - is a gas-liquid mass-transfer process that is used for adding
         oxygen during biological treatment processes, or for air stripping VOCs
         from wastewaters.

         Neutralization (pH Adjustment) - is a chemical process that involves
         adding an acid (e.g., sulfuric acid) or base (e.g., lime) to adjust the pH.
         Neutralization may be used as a pretreatment before biological or
         chemical treatment.

         Reverse Osmosis - is a physical separation process involving membrane
         filtration. Sufficient pressure is applied to a concentrated solution to
         force the water from the solution to flow through a semi-permeable
         membrane but selectively prevents impurities from passing through the
         membrane; concentrations of impurities build up on the pressure
         induced side of the membrane. Reverse osmosis is generally limited to
         polishing low flow streams containing highly toxic contaminants, and is
         especially effective for high molecular weight organics and ions.
                    II.  BIOLOGICAL

         Biological Treatment (In-Situ Bioremediation) - is an in-situ process that
         uses natural populations or seeded bacteria in an aquifer to transform
         organic contaminants (e.g., petroleum hydrocarbons) into less hazardous
         compounds thereby reducing the concentration of hazardous substances.
         The biological process generally involves the aerobic oxidation of organic
         compounds by bacteria, which produce water, carbon dioxide, and new
         biomass as products. In-situ biological treatment generally is
         accomplished via a ground water pump-and-reinjection system and is
         often limited by the ability to provide additional oxygen and nutrients to
         the bacteria.

         Ex-situ Bioremediation - is a batch process that  uses bacteria to degrade
         organic matter aerobically or anaerobically. Aerobic bioremediation
         involves the conversion of organics to carbon dioxide, water, and new
         bacteria cells. Anaerobic bioremediation generally involves the
         conversion of organics to carbon dioxide and methane gas in the absence
         of molecular oxygen. There are several biological treatment processes,
         including conventional activated sludge systems and fixed film systems
         (e.g.,  trickling filter, biotower).

                        III. OTHER

         Publicly Owned Treatment Works (POTW) - encompasses any device or
         system used in the treatment (including recycling and reclamation) of
         municipal or industrial wastes of a liquid nature, that is owned by a State
         or municipality, including sewers, pipes, or other conveyances if they
         convey wastewater to a facility providing treatment.
