 16. Abstract (Limit: 200 words)
   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-1960s  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/solvent 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 Record of Decision (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.

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 cleanup goals are based on achieving an excess
lifetime cancer risk of 10~6 .  Chemical-specific goals for soil include PCE 0.6 mg/kg,
TCE 0.07 mg/kg, and xylenes 259 mg/kg.   Ground water cleanup levels are the more
stringent of Federal MCLs or State standards, and include PCE 5 ug/1  (State), TCE 5
ug/1 (MCL), and xylenes 5 ug/1 (State).

SITE NAME, LOCATION. AND DESCRIPTION

The Mattiace Petrochemical Co., Inc. Site ("the Site"),  which
includes the 1.9 acre property owned by Mattiace Petrochemical
Co. Inc., is located on Garvey's Point Road in Glen Cove on Long
Island, New York (FIGURE 1).   LIMCO Manufacturing Corporation, a
precision sheet metal manufacturer, is located along the eastern
and southern border of the Mattiace property.  Property formerly
owned by Edmos, a knitting, dying, and finishing textile fabric
manufacturer, borders the Mattiace property to the west.  This
property is presently owned by 20 Garvey's Point Road Corporation
and is occupied by Medallion Oil Co. and various other tenants.
Undeveloped property owned by the Glen Cove Development
Corporation is located to the north of the Mattiace property.  A
residential area is located just north of this undeveloped area,
within one hundred yards of the.Mattiace property.  The study
area also contains the Garvey's Point Preserve, the Glen Cove
marina, residential areas, and other industrial facilities in
addition to those mentioned above.

The Mattiace facility is located approximately 500 feet directly
north of Glen Cove Creek.  The Creek empties into Hempstead
Harbor approximately 1500 feet west of the Mattiace facility. •
The facility, which is no longer active, is a fenced enclave
containing 32 underground and 24 aboveground chemical storage
tanks of various capacities.   Most of the underground tanks are
connected with an underground manhole piping system which
collected chemical overflows from the storage tanks as well as
stormwater.  This collection system leads to a solvent/
stormwater separator in the southeast part of the property where
any solvents were allowed to separate from water.  Although the
separator made it possible to skim the solvents for .proper
disposal and pump the remaining water to on-site leaching pools,
there were likely occasions when the entire contents of the
solvent/stormwater separator were pumped directly out to the
driveway at the southwest corner of the Site.

The property also includes the following: a metal Quonset
building, in which drum cleaning and reconditioning was
performed; a wetwell outside the Quonset building into which the
process liquids from drum reconditioning were discharged; a
concrete fire shed; and a concrete loading dock partially covered
by a slanted metal roof.  The south end of the property was a
truck parking area when the facility was operational.  See FIGURE
2 for a detailed diagram of the facility layout.

The regional geology in the Mattiace study area is generally
comprised of 3 unconsolidated sediments, namely, the Raritan
Formation, the Magothy Formation, and the Upper Glacial
Formation.  The Site is underlain by the Upper Glacial and
Magothy Formations, under which lays the Raritan Clay, which is a
minimum of 50 feet thick at the Site and of very uniform
composition locally.

-------
Groundwater is a source of drinking water for an estimated 44,000
people in the area, although there is presently no indication
that any water supplies are contaminated or in danger of
contamination as a result of conditions at the Site.  This is
because groundwater contamination from the Site moves generally
southwest toward Glen Cove Creek and Hempstead Harbor, with no
intervening public water supply wells.  The groundwater
contamination is also restricted to the Upper Glacial deposits
above the Raritan Clay, which suggests that contaminated
groundwater will ultimately discharge to surface water, i.e. the
Harbor or the Creek, and not travel beneath the Harbor or the
Creek.

SITE HISTORY AND ENFORCEMENT ACTIVITIES

The Mattiace Petrochemical Company began operating in the mid-
1960 's, receiving chemicals by tank truck, blending and
redistributing them to its customers.  The primary operations
were the storing, blending, and repackaging, of organic solvents.
These solvents were stored in aboveground and belowground tanks,
and they were blended and repackaged in 55 gallon drums under a
covered section of the concrete loading dock located in the
northeast corner of the property.  The 55 gallon drums were
stacked and temporarily stored on the loading dock prior to
shipment to various buyers.

The metal Quonset hut located in the western portion of the
property was used by the M and M drum cleaning operation to
clean, pressure test, and repaint drums.  The M and M operation
and the Mattiace operation were both owned by Mattiace
Industries.  The resulting aqueous/solvent mixture was collected
in a wetwell in the southeast'external corner of the Quonset hut.
The liquids in this wetwell were periodically discharged to one
of the adjacent aboveground tanks or into a leaching pool on the
property.

An underground tank farm used for the storage of organic solvents
is located in the northeast corner of the property.  Thirty two
underground and .twenty four aboveground storage tanks exist
mainly in the northeastern section of the Mattiace property.  The
underground tanks are interconnected by a spill prevention
system.  Excess material from overfilled tanks drain through a
series of four concrete manholes and discharge into the solvent/
stormwater separator which is located in the southeast corner of
the property.  This spill prevention system also acts as a
stormwater collection system.  Stormwater from the lower portion
of the separator was intended to be drained by gravity and then
pumped into the northwest leach pools.  However, the liquids
which collected in the separator and ponded in the southeast
corner of the property were sometimes pumped through a hose down
the Mattiace driveway while the facility was operational.

-------
In 1986, the Mattiace Petrochemical Company filed for bankruptcy
as a result of legal problems resulting from its non-compliance
with various environmental regulations.  At the request of the
State of New York, the Bankruptcy Court removed the protection of
assets normally extended to a reorganizing company in 1987 in
order to ensure that the Company ceased operations.  Meanwhile,
in August 1986, a Grand Jury handed up a 21 count charge against
the Company and three of its officers.  In May 1988, a jury
returned felony charges against the Company and its president.

On July 8, 1988, EPA notified William, Otto, and Louis Mattiace
of their status as potentially responsible parties at the
Mattiace Site, as well as provided them the opportunity to
remediate the Site through an EPA Consent Order.  No offer was
received by EPA in response to this notification.  In August,
1988, a Federal lien was placed on the Mattiace property by EPA.

HIGHLIGHTS OF COMMUNITY PARTICIPATION

A Community Relations Plan was developed for the Site by EPA
which designated the Glen Cove Public Library as the public
information repository.  All public information concerning the
Site, including the Site Administrative Record file, is presently
located at this repository.

The Proposed Plan for remediation at the Site which resulted from
the remedial investigation and feasibility study (RI/FS) was
mailed on May 14, 1991 to the Glen Cove Public Library  (as the
Site's public information repository) and to the individuals or
entities on the mailing list for the Site, which included State
and local officials and other interested parties.  General notice
of the availability of the Proposed Plan was placed in Long
Island Newsday on May 17, 1991 and the Glen Cove Pilot Record on
May 23, 1991 (FIGURES 3 and 4).  An EPA press release was also
issued on May 17, 1991.  A public meeting was held on May 30,
1991, to solicit public comment on the RI/FS and Proposed Plan.
The duration of the public comment period was 30 days and ended
on June 14, 1991.

All comments received by EPA during the public comment period are
responded to in detail in the Responsiveness Summary which is
attached as APPENDIX 4.

SCOPE AND ROLE OF OPERABLE UNIT

This response action complements two earlier response actions at
the Site.  EPA initiated a removal action at the Site in
February, 1988, which included waste characterization and off-
site disposal of approximately 100,000 gallons of hazardous
substances from aboveground and belowground tanks.  The removal
action was completed in June, 1988.

-------
Subsequently, EPA commenced a comprehensive RI at the Site in
October, 1989.  The RI included the following: a geophysical
survey; a soil gas survey (FIGURE 5);  installation and sampling
of 11 groundwater monitoring wells and two piezometers (FIGURE 6,
which also shows 4 wells installed as  part of the preliminary
investigation conducted by Woodward Clyde); drilling and sampling
of 22 soil and 3 hand augur borings (FIGURE 7); and sampling of
Glen Cove Creek water and sediments (FIGURE 8).

The geophysical survey was performed to assess, among other
things, the possibility that hazardous substances were disposed
of through burial on-site.  The survey indicated that several
areas at the Site should be further investigated because of the
possibility of buried drums of hazardous substances.  Therefore,
EPA initiated the second operable unit focused feasibility study
(FFS) in December, 1989 to further define the findings of the
geophysical investigation.  With the creation of the second
operable unit at the Site, all other elements of the Site
investigation were designated as first operable unit activities.

The second operable unit investigation's objectives consisted of
the identification of any buried drums which contained hazardous
substances, as well as the identification of significantly
contaminated soils.  The investigation concentrated on three
areas at the site which were suspected of being used for drummed
hazardous waste disposal.  EPA found an estimated 25-50 drums
buried in the area designated source area 1, which is located
along the western perimeter of the Site.  No drums were found in
any of the other suspected source areas.  An FFS report was then
issued which became the basis for the  EPA's September 27, 1990
Record of Decision (ROD.) for remediation of source area 1 (FIGURE
9).  Remedial action implementing the  remedy selected in that ROD
is presently underway and should be completed shortly.

The overall goal of the first operable unit investigation, which
is the investigation upon which this ROD is based, is to reduce
the concentrations of all Site contaminants to levels which are
protective of human health and the environment.

EPA believes that the selected remedy will achieve this goal by
meeting the following remedial action objectives:

1) reduce to acceptable levels the on-site potential health
effects associated with contaminated soils and residual leakage
from underground tanks;

2) minimize the off-site migration of contaminated groundwater
and surface runoff to potential environmental receptors; and,

3) restore the groundwater currently being degraded as a result
of the Site to its most beneficial use.

-------
SUMMARY OF SITE CHARACTERISTICS

The soil contamination at the Site is extensive" across the entire
facility area, with "hot spots" of contamination occurring in
several locations on the Site (one of these "hot spots", the
buried drum area along the western boundary of the Site, is
presently being remediated pursuant to the second operable unit
ROD).  These locations are generally associated with seven groups
of underground storage tanks on the Site, as well as three other
locations corresponding to soil boring numbers 5, 9, and 11,
which are all contaminated primarily with pesticides.  Some of
the more frequently occurring contaminants of concern in the soil
(with maximum concentrations in parentheses) were:
tetrachloroethylene (410 milligrams/killigram, or mg/kg),
trichloroethylene (37 mg/kg), xylenes (2,600 ing/kg) , and 1,4-
alpha chlordane (9 mg/kg) (TABLE 1).

The RI also determined the existence of severe groundwater
contamination in the Upper Glacial aquifer beneath the Site.
Additional data gathered from previous investigations in the
Garvey's Point area and reviewed by EPA indicate pervasive
groundwater contamination in the area, most likely as a result of
its commercial/industrial nature.  The groundwater contamination
attributable to the Site is particularly severe, and includes a
localized layer of "floating product" at the top of the water
table directly under the Site.  This "floating product" consists
of approximately 15,000 gallons of a mixture of organic
chemicals, including total xylenes (6% by weight),
trichloroethylene (12%), tetrachloroethylene  (10%), and toluene
(12%).  Excluding the "floating product", analysis of groundwater
during the RI indicates the following concentrations of some
contaminants of concern:  tetrachloroethylene  (100
milligrams/liter, or mg/1), trichloroethylene  (230 mg/1),
chloroform (81 mg/1), ethylbenzene (370 mg/1), xylenes  (422
mg/1), methylene chloride (750 mg/1), isophorone (57 mg/1), and
1,2-dichlorobenzene (5.3 mg/1) (TABLE 2).  These concentrations
are several orders of magnitude above Federal and state drinking
water standards.  The movement of groundwater in the Upper
Glacial aquifer in the vicinity of the Site is slow and generally
in a southwest direction toward Glen Cove Creek.  On the basis of
the RI, as well as other information sources considered during
the investigation, EPA believes that none of the area's potable
water supply wells are in locations that would cause them to be
presently affected or threatened by the groundwater contamination
from the Site.

Moreover, it is likely that contaminated groundwater, as well as
surface water runoff from the Site, is responsible for a portion
of the contamination that EPA detected in Glen Cove Creek's
sediments.  It is very difficult to delineate and quantify the
constituents which could be directly related to the Site given
the documented releases of organic chemicals from other

-------
facilities in the area, many of which are the same as those
substances released from the Mattiace facility*  EPA's sampling
of the Creek's sediments indicated elevated concentrations of
organic contamination, particularly semi-volatile compounds such
as bis (2-ethylhexyl)phthalate (21 mg/kg),  fluoranthrene (7
mg/kg), and pyrene (6 mg/kg) (FIGURE 10).  Some inorganics, such
as aluminum and iron, were also found in high concentrations.
The semi-volatile compounds detected in the Creek sediments were
also found on the Site during the RI but in relatively low
concentrations and minor frequency of occurrence.  Therefore, it
is possible that the Site is a source of these compounds in the
Creek sediments, but the amount of contribution is similarly
difficult to quantify.

SUMMARY OF SITE RISKS

A baseline risk assessment was developed as part of the remedial
investigation for the Site.  The risk assessment evaluates the
potential impacts on human health and the environment if the
contamination at the Site is not remediated.  This information is
used by EPA to make a determination as to whether remediation of
the Site is required.

EPA evaluated nearby residents and others who might spend
extended periods of time on or around the Site under a current
land use scenario.  EPA also used a scenario based on future
residential land use at the Site in order to assess the maximum
plausible risk that the Site could pose.  Under both scenarios,
several exposure pathways (direct contact,  inhalation and
ingestion) were evaluated for surface and subsurface soils and
air, while exposure to groundwater (ingestion, contact, and
inhalation) was evaluated only for the future use scenario.
Exposure assumptions were made that would include current nearby
residents/workers and future on-site residents, including
children, as the receptors  (or potential receptors).  An exposure
assessment was conducted to estimate the magnitude, frequency,
and duration of actual and/or potential exposures to the
chemicals of potential concern via all pathways by which humans
are potentially exposed.  Reasonable maximum exposure is defined
as the highest exposure that is reasonably expected to occur at
the Site for individual and combined pathways.

For known or suspected carcinogens, acceptable exposure levels
are generally concentration levels that theoretically represent
an excess upper bound lifetime cancer risk to an individual of
between IxlO"4 (or one incident of Site-related cancer among an
exposed population of 10,000 people) to 1x10* (or one incident of
Site-related cancer among an exposed population of 1,000,000
people).  EPA derives this risk by using existing information on
the relationship between dose of carcinogen and carcinogenic
response.  The 10* risk level is used as the point of departure
for determining remediation goals for alternatives when

-------
regulatory standards or requirements are not available or are not
sufficiently protective.

For systemic toxicants, acceptable exposure levels generally
represent concentration levels to which the human population,
including sensitive subgroups, may be exposed without adverse
effect.

Selection of Contaminants of Concern

Contaminants which have inherent toxic/carcinogenic effects that
are likely to pose the greatest concern with respect to the
protection of public health and the environment, and that were
detected at the Site in significant concentrations and/or
frequencies of occurrence were selected as contaminants of
concern.  The contaminants of concern at the Mattiace Site are
presented in TABLE 3.

Exposure Assessment

An exposure pathway is the course a contaminant takes from the
source to the exposed receptor.  Exposure pathways in general
must consist of the following four elements:

     1.  a source and mechanism of constituent release;
     2.  a retention or transport medium;
     3.  a point of.potential human contact with the medium; and
     4.  an exposure route at the contact point.

In this assessment, both current and potential future exposure
pathways are considered.  Current activity patterns at the Site
are examined to identify current exposure potential to residents
and workers near the Site as it presently exists.  In developing
future exposure pathways, it is assumed that no further remedial
actions will be undertaken.  It is further assumed that a
residential development may be constructed on the Mattiace
property, and that exposure to contaminants in soils may occur
during and after the construction.

To quantitatively assess the potential risks to human health
associated with the exposure scenarios considered in this
assessment, estimates of chronic daily intakes (GDIs) are
developed.  GDIs are expressed as the amount of a substance taken
into the body per unit body weight per unit time, or mg/kg/day.
A GDI is averaged over a lifetime for carcinogens and over the
exposure period for noncarcinogens.  An average case and a
reasonable maximum case are considered.  The average case is
based on average (but conservative) conditions of exposure and
the average exposure point concentrations.  The reasonable
maximum case is based on upper-bound conditions of exposure and
the reasonable maximum exposure point concentration, and as such
represents the extreme upper limit of potential exposure.

-------
Toxicitv Assessment

Cancer potency factors (CPFs) have been developed by EPA's
Carcinogenic Assessment Group for estimating excess lifetime
cancer risks associated with exposure to potentially carcinogenic
chemicals.  CPFs, which are expressed in units of (mg/kg/day)-1,
are multiplied by the estimated intake of a potential carcinogen,
in mg/kg/day, to provide an upper bound estimate of the excess
lifetime cancer risk associated with exposure at that intake
level.  The term "upper bound" reflects the conservative estimate
of the risks calculated from the CPF.  Use of this approach makes
the underestimation of the actual cancer risk highly unlikely.
CPFs are derived from the results of human epidemiological
studies or chronic animal bioassays to which animal-to-human
extrapolation and uncertainty factors have been applied.

Noncarcinogenic risks were assessed using a hazard index (HI)
computed from expected daily intake levels.(subchronic and
chronic) and reference doses, or RfDs (representing acceptable
intakes).  Potential concern for noncarcinogenic effects of a
single contaminant in a single medium is expressed as the hazard
quotient (HQ).  This is the ratio of the estimated intake
(derived from the contaminant concentration in a given medium) to
the contaminant's RfD.  By adding the HQs for all contaminants
within a medium or across all media to which a given population
may reasonably be exposed, the HI can be generated. The HI is
useful as a reference point for gauging the potential effects of
environmental exposures to complex mixtures.  In general, His
which are less than one are not likely to be associated with any
health risk, and are therefore less likely to be of concern than
His greater than one.

For a listing of the indices of toxicity, i.e. RfDs, CPFs (or
slope factors), please see TABLE 4.

In accordance with EPA's guidelines for evaluating the potential
toxicity of complex mixtures, it was assumed that the toxic
effects of the Site-related chemicals would be additive.  Thus,
lifetime excess cancer risk and the CDI:RfO ratios were summed to
indicate the potential risks associated with mixtures of
potential carcinogens and noncarcinogens, respectively.

Under current EPA guidelines, the likelihood of carcinogenic and
noncarcinogenic effects as a result of exposure to Site chemicals
are considered separately.

Risk Characterization

The risk characterization quantifies present and/or potential
future threats to human health that result from exposure to the
contaminants of concern.  EPA calculated significant carcinogenic

-------
risks associated with prolonged exposure to contaminated soils on
the Mattiace property.  Reasonable maximum exposure risks for
adults were on the order of SxlO"3 for inhalation,  and 2X10"3  for
dermal absorption, with even greater risks posed for sensitive
populations, such as children.  Inhalation risks were chiefly as
a result of airborne volatile organic compounds, particularly
trichloroethylene.  The dermal absorption risk Was chiefly as a
result of semi-volatile pesticides in the soils.  Adult non-
carcinogenic risks from these types of exposures were also
significant, with hazard indices ranging from 6.3 for inhalation
(mainly from a variety of airborne volatile organic compounds) to
23 for dermal absorption (mainly from alpha chlordane, a
pesticide).

EPA also calculated the risk to public health associated with
exposure to contaminated groundwater, even though no exposures
are presently occurring, as part of the future residential use
scenario.  EPA calculated an adult carcinogenic risk from the
exposure to groundwater directly beneath the Site of SxlO'1 for
groundwater ingestion (chiefly from a variety of volatile organic
compounds), and 3xlO"2 for dermal absorption (chiefly from the
volatile organic compounds carbon tetrachloride and vinyl
chloride).  Adult non-carcinogenic effects were also significant,
with hazard indices ranging from 4,730 for groundwater ingestion
(chiefly from carbon tetrachloride) to 195 for dermal absorption
(chiefly from carbon tetrachloride).  For a complete listing of
the health effects criteria and the calculated adult risks for
various chemicals and exposure pathways, see TABLE 4.

Moreover, contaminated groundwater, as well as surface water
runoff from the Site, is likely responsible for a portion of the
contamination that EPA found in Glen Cove Creek's sediments.
Since most of the contaminants found in high concentrations
exhibit low water solubility and a high affinity for adsorption
to sediments, it would be expected that they would tend to remain
in the sediments with little dissolution in the overlying water
column.  Therefore, any release of these contaminants from the
sediment to the water column should be insignificant relative to
the amount of tidal "flushing" of Creek water that takes place.
EPA considered human exposure to these sediments an unlikely
possibility (in particular chronic long-term exposure), because
of the present use and physical nature of the Creek, i.e., boat
traffic, bulkheaded (no exposed sediments), etc.  Therefore, only
the risk associated with exposure to Creek water was evaluated.
This assessment indicates that no unacceptable risks to public
health are posed by the low contaminant concentrations found in
the Creek water.

Since the Creek is contiguous with Hempstead Harbor, and
ultimately with Long Island Sound, the contamination from the
Site has the potential to affect any of the species of flora and
fauna that use or inhabit these environs, although the degree of

-------
                               10

the effects is difficult to quantify and would depend,  among
other things, on the duration of exposure and on the particular
species exposed.

More specific information concerning public health risks is
contained in the volume entitled Remedial Investigation Report-
Mattiace Petrochemical Site (Chapter 6-Human Health Risk
Assessment) located at the Glen Cove Public Library.

Uncertainties

The procedures and inputs used to assess risks in this
evaluation, as in all such assessments, are subject to a wide
variety of uncertainties.  In general, the main sources of
uncertainty include:

- environmental chemistry sampling and analysis
- environmental parameter measurement
- fate and transport modeling
- exposure parameter estimation
- toxicological data

Uncertainty in environmental sampling arises in part from the
potentially uneven distribution of chemicals in the media
sampled.  Consequently, there is significant uncertainty as to
the actual levels present.  In the case of soils, the
conservative models used assume that the contaminant is present
at the maximum detected concentration throughout the volume of
soils being examined.  Environmental chemistry analysis error can
stem from several sources, including the errors inherent in the
analytical methods, chain of custody problems, and
characteristics of the matrix being sampled.  Environmental
parameter measurements primarily contribute to uncertainty
because little verified information is available.

In the Site risk assessment there are uncertainties regarding the
estimates of how often, if at all, an individual would come in
contact with the chemicals of concern and the period of time over
which such exposure would occur.  In particular, this applies to
the future residential exposures.  There is also significant
uncertainty in the models used to estimate exposure point
concentrations.

Toxicological data error  (potentially occurring in extrapolating
both from animals to humans and from high to low doses) is also a
large source of potential error in this risk assessment.  There
is also a great deal of uncertainty in assessing the toxicity of
a mixture of chemicals..  In this assessment, the effects of
exposure to each of the contaminants present in the environmental
media have initially been considered separately.  The separate
evaluation and subsequent summation of contaminant-specific risk
may not account for potential synergistic or antagonistic

-------
                                11

interactions of chemical mixtures.

In summary, actual or threatened releases of hazardous substances
from this Site, if not addressed by the selected remedy or one of
the other active measures considered,  may present a current or
potential threat to public health and the environment through, at
a minimum, any of the following exposure pathways: inhalation of
particulates and/or vapors from contaminated soils, dermal
absorption of contaminated soils, under both the current land use
and a future residential land use scenario, and ingestion,
inhalation or dermal absorption of contaminated groundwater under
a future residential land use scenario.

The FS, in which remedial alternatives are developed, screened,
and then carefully evaluated in detail, forms the basis for the
selected remedy.

DESCRIPTION OF ALTERNATIVES

CERCLA requires that each selected Site remedy be protective of
human health and the environment, be cost effective, comply with
other statutory laws, and utilize permanent solutions,
alternative technologies, and resource recovery alternatives to
the maximum extent practicable.  In addition, the statute
includes a preference for the use of treatment as a principal
element for the reduction of toxicity, mobility, or volume of the
hazardous substances.

The remedial alternatives considered in the FS are organized
according to the media which they address: soil contamination
("SC") and management of migration of groundwater  ("MOM").  These
alternatives were screened based on implementability,
effectiveness, and cost.  The screening resulted in remedial
alternatives upon which a detailed analysis was performed.  A "no
action" alternative was also evaluated in the FS, as required by
regulation, to provide an appropriate alternative in the event
that no contravention of standards nor significant health or
environmental risks were identified as a result of the Site
contamination.

The alternatives presented below are those which were evaluated
in detail following the preliminary screening of alternatives.
These alternatives have retained their pre-screening
alphahumerical designations in order to correspond with the
descriptions of the alternatives which are contained in the FS
report.  The present worth costs are estimates which take into
account both the capital cost and the operation and maintenance
(0 and M) costs for up to 30 years.  "Time to implement"  is
defined as the period of time needed for the alternative to be
started (e.g., amount of time needed for design and construction
of a treatment facility).  The remedial alternatives considered
for addressing the soil contamination at the site are as  follows:

       Pesticide "Hot Spots"/Excavation of Pesticide "Hot Spots"

     Present Worth Cost: $245,656
     Time To Implement: 2 months

The Superfund program requires that the no action alternative be
considered as a baseline for comparison with other alternatives.
Under this alternative, the contaminated soil would be left in
place without treatment.  Also, installation of additional
security measures, such as repairs and modifications as necessary
to the existing fencing and the use of electronic devices to
detect trespassing (with subsequent notification of local
authorities) would be performed as needed.  No action would also
include a public education program in order to increase public
awareness of Site conditions and hazards.  Since this alternative
would involve no contaminant removal, CERCLA requires that the
Site be reviewed every five years.  If justified by the review,
remedial actions may be implemented in the future to remove or
treat the wastes.

SC-3: a. In Situ Vacuum Extraction of General Site Area/
      Excavation of All "Hot Spots" with Off-Site Treatment and
      Disposal

       Capital Cost:  $17,896,733
       Annual O&M Cost: $73,699
       Present Worth Cost:  $18,097,415
       Time To Implement: 36 months

-------
                                13

This alternative involves in situ treatment of 11,950 cubic yards
(cy) of contaminated soil by means of vacuum extraction,  and
excavation of 6,956 cy of soil  (which includes excavation soil
expansion factor).  For costing purposes, off-site treatment was
assumed to be incineration, although other more innovative
technology may eventually be selected on the basis of cost and
treatment equivalence.

In situ extraction, or removal of organic contaminants from the
soil without major soil disturbance, is accomplished by
installing soil vapor extraction wells at strategic points,
manifolding the wells, and applying a vacuum in order to draw
contaminated soil gases out of the ground and into a treatment
system.  The treatment system is comprised of a vapor/liquid
separator.  It was assumed that an activated carbon canister
would be utilized for off-gas emission, although equivalent
technologies could be utilized.  Spent activated carbon would be
regenerated for re-use at an off-site location.  The in situ
vacuum extraction system would be operated until soil cleanup
levels corresponding to EPA's target risk level of IxlO^are
achieved.

The soil cleanup levels of selected indicator chemicals which
have been determined by EPA to correspond to a IxlO"6 risk level
are given below:

CHEMICAL                     CLEANUP LEVEL
                                (mg/kg)
Volatile Oraanics

Tetrachloroethylene              0.6
Trichloroethylene                0.07

Alpha Chlordane                  0.5
Heptachlor Epoxide               0.07

The excavation of soils for off-site treatment and disposal would
include excavation of all soil "hot spots", or areas of soil
contamination that is more highly concentrated than the
surrounding soil contamination at the Site.  The off-site
transportation, treatment, and disposal would conform to
applicable/appropriate requirements of the Resource Conservation
and Recovery Act  ("RCRA"), including land disposal requirements
("LDR"), as well as the requirements of State hazardous waste
laws and regulations.  Any hazardous residuals resulting from on-
site vacuum extraction treatment would be similarly disposed of
or recycled off-site.  Clean fill would be used to backfill

-------
                                14

excavated areas.  EPA believes that this alternative would be
effective in achieving reduction of human carcinogenic risk posed
by contaminated soils at the Site to approximately IxlO"6.

This alternative would also include the decontamination (as
necessary), demolition, removal, and landfill disposal of the
Quonset hut, 24 aboveground storage tanks, 32 underground storage
tanks, and 1,360 cy of concrete and asphalt.   Treatability
studies would also have to be performed to determine design
parameters and the need for treatment of off-gases for the vacuum
extraction system.

SC-3: b. In Situ Vacuum Extraction of General Site Area and Non-
         Pesticide "Hot Spots11/ Excavation of Pesticide "Hot
         Spots" with Off-Site Treatment and Disposal

          Capital Cost:  $3,227,566
          Annual O&M Cost: $100,138
          Present Worth Cost: $3,500,242
          Time to Implement: 36 months

This alternative is the same as Alternative SC-3a, with the
exception that only the pesticide "hot spots" would be excavated
for off-site treatment and disposal, while the remaining soils
would be treated on-site to meet the cleanup levels specified in
Alternative SC-3a using in situ vacuum extraction technology.

Specifically, this alternative would involve in situ treatment of
17,141 cy of contaminated soil by means of vacuum extraction, and
excavation of 208 cy of soil (which includes excavation soil
expansion factor) contaminated primarily with pesticides for off-
site treatment and disposal, in accordance with applicable/
appropriate requirements of RCRA, as well as the requirements of
State hazardous waste laws and regulations.  For costing
purposes, off-site treatment was assumed to be incineration,
although other more innovative technology may eventually be
selected on the basis of cost and treatment equivalence.

The excavation of soils for off-site treatment and disposal would
only include excavation of the pesticide "hot spots".  Clean fill
would be used to backfill excavated areas.  EPA believes that
this alternative would be effective in achieving reduction of
human carcinogenic risk posed by contaminated soils at the Site
to approximately 1x10*.

This alternative would also include the decontamination (as
necessary), demolition, removal, and landfill disposal of the
Quonset hut, 24 aboveground storage tanks, 32 underground storage
tanks, and 1,360 cy of concrete and asphalt.  Treatability
studies would also have to be performed to determine design
parameters and the need for treatment of off-gases for the vacuum
extraction system.

          Present Worth Cost: $3,004,068
          Time To Implement: 36 months

This alternative is the same as alternative 8C-3b, with the
exception that the pesticide "hot spots" would not be excavated
for off-site treatment and disposal.  Specifically, this
alternative involves in situ vacuum extraction of the entire
contaminated soil volume of 17,301 cy to the soil cleanup levels
specified in Alternative 8C-3a for volatile organics.  However,
cleanup levels for pesticides would not be attainable in the
pesticide "hot spots", since the three pesticides of concern at
the Site are not significantly affected by vacuum extraction
technology.

EPA believes that this alternative would be effective in    '  .
achieving reduction of human carcinogenic risk posed by
contaminated soils at the Site to approximately IxlO"4.   This
increase in potential human health risk is caused by leaving the
3 localized pesticide "hot spots" on-site (totalling 160 cy
compacted volume).

This alternative would also include the decontamination (as
necessary), demolition, removal, and landfill disposal of the
Quonset hut, 24 aboveground storage tanks, 32 underground storage
tanks, and 1,360 cy of concrete and asphalt.  Treatability
studies would also have to be performed to determine design
parameters and the need for.treatment of off-gases for the vacuum
extraction system.

     Annual O&M Cost: $1,089,526
     Present Worth Cost: $11,344,791
     Time To Implement: 33 months

In this alternative, approximately 22,490 cy (which includes
excavation soil expansion factor) of contaminated soils would be
excavated and then fed into a low-temperature thermal processor
located on-site.  The processor would operate at a temperature of
approximately 400° F, which  is  sufficient  to  vaporize the  organic
compounds, including the pesticides, present in the soils.  After
treatment, the soil would be tested to assure it meets both RCRA
and the soil cleanup levels specified in Alternative SC-3a prior
to being used as backfill.  Treatment of off-gases from this

-------
                                16

alternative, through the use of carbon or an equivalent
technology, has been assumed necessary to comply with the Clean
Air Act and applicable/appropriate State stack emission
regulations.  This assumption would be confirmed during design
testing.

EPA believes that this alternative would be effective in
achieving reduction of human carcinogenic risk posed by
contaminated soils at the Site to approximately IxlO"6.

This alternative would also include the decontamination (as
necessary), demolition, removal, and landfill disposal of the
Quonset hut, 24 aboveground storage tanks, 32 underground storage
tanks, and 1,360 cy of concrete and asphalt.  Treatability
studies would also have to be performed to determine design
parameters and the need for treatment of off-gases for the vacuum
extraction system.

The no action alternative for groundwater would involve semi-
annual monitoring of groundwater monitoring wells associated with
the Site, in order to assess future movement of the groundwater

water and sediments would also be included as part of the
monitoring plan.

In this alternative, extraction and injection wells would be
installed into the contaminated groundwater plume.  For costing
purposes, EPA estimated that 8 extraction wells would be required
in order to capture and remove the plume of contaminated
groundwater.  First, the "floating product" beneath the Site
would be removed through the extraction wells with a skimmer
pump, with subsequent off-site treatment and disposal in
accordance with the appropriate requirements of RCRA.  Next, the
contaminated groundwater would be pumped, pretreated through
precipitation and clarification to remove iron and manganese
(these metals would interfere with subsequent treatment) and
treated via air stripping to remove volatile organics.  The air
effluent would then be thermally treated to meet the
applicable/appropriate requirements of the Clean Air Act and
State laws and regulations.  The water effluent from the air
stripper would be carbon-treated in order to reduce the level of
any remaining organic contaminants to meet applicable/
appropriate requirements of the Safe Drinking Water Act and State
laws and regulations prior to reinjection into the ground through
groundwater reinjection wells.  For costing purposes, EPA
estimated that four reinjection wells would be necessary.  Actual
locations of extraction and reinjection wells would be determined
from additional groundwater monitoring during the design phase of
the project.  Spent activated carbon would be regenerated at an
off-site location for reuse.  Any hazardous residuals resulting
from on-site treatment would be disposed of off-site in
accordance with the applicable/appropriate requirements of RCRA
and State hazardous waste laws and regulations.

Annual monitoring of Glen Cove Creek's water and sediments would

EPA would conduct 5 year reviews of the Site as CERCLA requires
in order to ensure that the human health and the environment were

This alternative is the same as MOM-3/ except in the method of
contaminated groundwater treatment.  Under MOM-6, an ultraviolet
radiation/oxidation system would be utilized to treat organic
contaminants from the extracted groundwater to acceptable levels.
Off-gas and water effluents from this treatment process would be
further "polished" in an ozone reduction unit (air) and in a
carbon unit (water).  The carbon unit would reduce the level of
any remaining organic contaminants to meet applicable/
appropriate requirements of the Safe Drinking Water Act and State
laws and regulations, prior to reinjection into the ground
through groundwater reinjection wells.

This alternative would also involve semi-annual monitoring of
groundwater monitoring wells associated with the Site, in order
to assess future movement of the groundwater plume of
contamination.  Annual monitoring of Glen Cove Creek's water and
sediments would also be included as part of the monitoring plan.
In addition, EPA would conduct 5 year reviews of the Site as

SUMMARY OF COMPARATIVE ANALYSIS OF ALTERNATIVES

The selected remedy for the first operable unit at the Site is a
combination of BC-3b (In Situ Vacuum Extraction of General Site
Area and Non-Pesticide "Hot Spots11/ Excavation of Pesticide "Hot
Spots" with Off-Site Treatment and Disposal) and MOM-3
(Groundwater Extraction/ Air Stripping/ Carbon Adsorption of
Water Effluent/ Thermal Treatment of Air Effluent/ Reinjection of
Treated Effluent).  Based on current information, this.
combination of alternatives offers the best balance among the
nine evaluation criteria that EPA uses as a means of evaluating
remedial actions.

This section provides a glossary of the nine criteria and an
analysis, with respect to these criteria, of the remedial
alternatives which were evaluated for the Site.

Glossary of Evaluation criteria

o Overall protection of human health and the environment
addresses whether a remedy provides adequate protection and
describes how risks are eliminated, reduced, or controlled
through treatment, engineering controls, or institutional

-------
                                19

controls.

o Compliance with ARARs addresses whether a remedy will meet all
of the applicable or relevant and appropriate requirements
(ARARs) and/or provide grounds for invoking a waiver of ARARs.

o Short-term effectiveness addresses the period of time needed to
achieve protection against any adverse impacts on human health
and the environment that a Site may pose during the construction
and implementation period of an alternative.

o Long-term effectiveness and permanence refers to the ability of
a remedy to maintain reliable protection of human health and the
environment over time once cleanup goals have been met.  It also
addresses the magnitude and effectiveness of the measures that
may be required to manage the risks posed by treatment residuals
and/or untreated wastes.

o Reduction of toxicity. mobility, or volume refers to the
anticipated performance of the treatment technologies with
respect to these parameters.

o Implementability involves the technical and administrative
feasibility of a remedy, including the availability of materials
and services needed to implement the chosen solution.

o Cost involves both capital and O and M costs. Cost comparisons
are made on the basis of present worth values, which have both
capital and O and M costs factored in.

o State acceptance indicates whether the State concurs with,
opposes, or has no comment on the preferred alternative.

o Community acceptance indicates whether the community concurs
with, opposes, or has no comment on the preferred alternative.


Analysis

Analysis of Soil Alternatives

     o Overall Protection of Human Health and the Environment

Alternative SC-1 (No Action) would only offer minimal protection
of human health through reduction of the present direct contact
threat by further limiting Site access.  The related benefits are
minimal since the Site already has an effective level of
restricted access.   Relative to the environment, this alternative
would not provide any increased protection to flora and fauna
over the present baseline condition.  Given the present risk
levels at the Site and the level of risk reduction and
environmental benefit expected from the implementation of each

-------
                                20

alternative, EPA considers all of the alternatives for source
control, except for the no action alternative,  to be sufficiently
protective of human health and the environment.  The no action
alternative is therefore unacceptable, and is eliminated from
further analysis.  Each of the alternatives (except no action)
utilizes treatment to eliminate the principal threat posed by the
Site soils.  8C-3a and b, and 8C-5 would provide the highest
degree of protectiveness, while SC-3c would provide less, but
adequate protection of human health and the environment.

     o Compliance with ARARs

The technologies proposed for use in Alternatives SC-3a, b, and
c, as well as 8C-5 would be designed and implemented to meet all
ARARs.  Federal and state regulations dealing with the handling
and transportation of hazardous wastes to an off-site treatment
facility would be followed.  Alternatives SC-3a and b would
require consideration of LDRs since each would require off-site
treatment of soils.  The responsibility for meeting applicable
LDRs would rest with the off-site treatment and disposal
facility.  Alternative SC-3c would not require consideration of
LDRs since no excavation and placement of hazardous substances
would occur during implementation.  Alternative SC-5 is expected
to meet applicable LDRs.  Likewise, Alternative 8C-5 is expected
to meet appropriate closure requirements by achieving "hybrid"
clean closure, which is a combination of closure considerations
and requirements taken from both the RCRA and CERCLA programs.
Hybrid clean closure is achieved when the treated matrix (soil,
in this case) to be land disposed will not pose a direct contact
threat, nor will groundwater be adversely affected by leachate
from the treated matrix.

     o-Short-term Effectiveness

Alternatives SC-3a, b, and c would all require approximately 3
years to design and construct, while 8C-5 would take between two
and three years to design and construct.  Once constructed,
Alternatives 8C-3a and b would reduce risks associated with
contaminated soil most rapidly since they involve limited
excavation and offsite disposal of the high risk areas of
contamination.  Once constructed, 8C-3a would take approximately
2.5 years to effectively reduce the levels of soil contaminants
to the target levels (related excavation under 8C-3a would be
accomplished relatively quickly and, in any event, well before
the in situ treatment is completed).  The 8C-3b, 8C-3c and 8C-5
alternatives would require a slightly longer.time, approximately
3 years, to complete treatment after being constructed.
Treatment-related impacts would likely be the greatest for
Alternative SC-5 since it requires the largest amount of
contaminated soil excavation and because it involves on-site
thermal treatment of all contaminated soils prior to replacement
on-site.  Treatment-related impacts for the 8C-3 alternatives

-------
                                21

involving in situ vapor extraction would be minimal.  Short-term
impacts for excavation under 8C-3a and b would be a concern
mainly for Site workers, but such concerns should be minimized
through development and adherence to appropriate health and
safety protocols.

     o Long-term Effectiveness and Permanence

All of the soil alternatives involve treatment technologies that
have been utilized previously at other Superfund sites, i.e., in
situ vacuum extraction, low temperature thermal treatment, and
excavation with off-site treatment and disposal.  Based on the
demonstrated effectiveness of these technologies at other sites,
all of the 8C-3 alternatives, as well as the 8C-5 alternative,
should result in permanent risk reduction so that risks
associated with remediated soils are within EPA's acceptable risk
range.  The SC-3 alternatives will accomplish this primarily
through in situ vacuum extraction, with additional reductions of
risk under 8C-3a and b through the excavation of soil "hot
spots".  8C-3c would only achieve risk reduction to IxlO"1, .which
is the level of risk presently associated with the pesticide "hot
spots" (not readily treatable via vacuum extraction).

     o Reduction of Toxicity. Mobility, or Volume

All of the treatment alternatives under consideration would
reduce the volume and concentrations of soil contaminants to
health-based residual levels.  This in turn would eliminate the
non-carcinogenic toxicity of Site contaminants while reducing
carcinogenic risk factors to within the EPA-acceptable risk
range.  The mobility of residual Site contaminants would be
unaffected, as none of the alternatives under consideration rely
on containment technology.

     o Implementability

:PA believes that all of the soil alternatives presently under
consideration are implementable in terms of the materials and
services that would be needed, as well as from the standpoint of
administrative requirements or restrictions that presently exist.
Alternatives 8C-3a, b/ and c would require the performance of
treatability studies for the in situ vacuum extraction technology
in order to determine essential design parameters.

     o Cost

The relative present worth costs of the soil remediation
alternatives are given below:

     Alternative   Capital Cost	O&M Cost   Present Worth Cost

     SC-3a         $17,896,733      $73,699       $18,097,415

-------
                                22

     SC-3b          $3,227,566     $100,138        $3,500,242
     SC-3C          $2,731,392     $100,138        $3,004,068
     8C-5           $8,378,012   $1,089,526       $11,344,791

As can be seen from the table, Alternative 8C-3a is significantly
more expensive than the other source remediation alternatives,
while Alternative 8C-3c is the least expensive alternative in
terms of present worth costs.

     o State Acceptance

The State of New York has reviewed and concurs with the selected
remedy (see State letter of concurrence- APPENDIX 3).

     o Community Acceptance

EPA concludes that the selected remedy has the support of the
affected community based on the comments .received during the
public comment period, including those comments received during
the public meeting held on May 30, 1991.

Analysis of Water Alternatives

     o Overall Protection of Human Health and the Environment

Alternative MOM-1, or no action (monitoring only),  provides no
increase in protection for either public health or the
environment.  Given the high degree of future risk posed by
ingestion of and dermal contact with contaminated groundwater,
together with the uncertainty of the legislative feasibility and
long-term effectiveness of institutional controls (local or state
restrictions on access to groundwater in the area of
contamination), EPA believes that the no action alternative
cannot assure long-term protection of public health.  Selection
of the no action alternative would also have no effect on
mitigating presently unquantified impacts occurring in the waters
of Glen Cove Creek and Hempstead Harbor, and to a lesser extent,
Long Island Sound, as a result of the groundwater contamination
from the Site.  The no action alternative is therefore
unacceptable, and it has been eliminated from further analysis.
Alternatives MOM-3 and MOM-6 both involve extraction and
treatment of the groundwater plume.  The alternatives vary in the
types of treatment employed after extraction; however, the
treatments employed under each alternative would result in
air/water effluents that meet applicable discharge or emission
standards.  Further, both of these alternatives would be
similarly effective in protecting human health and the
environment by preventing off-site migration of contaminated
groundwater as well as by reducing future risks posed by
ingestion of and dermal contact with groundwater contamination
emanating from the Site.

-------
                                23

     o Compliance with ARARs

Alternatives MOM-3 and MOM-6 should both eventually meet potable
water ARARs (primarily 10 NYCRR Part 5 regulations) as a result
of the accelerated pumping and treatment activity common to these
alternatives, as well as the cleanup of contaminated soils which
have directly contributed to the groundwater contamination.
However, groundwater contamination may be especially persistent
in the immediate vicinity of the contaminants' source, where
concentrations are very high.  Also, the ability to meet potable
water ARARs within the Site's plume, or area of attainment, may
also be hindered by the phenomenon of low concentration
adsorption, which occurs during extended pumping of' contaminated
groundwater.  This phenomenon has been experienced during other
Superfund groundwater pump-and-treat remedial actions, as well as
documented empirically in bench and pilot scale studies.  In
addition, it is important to note that the actual attainment of
groundwater ARARs may be further restricted because of the
existence of other areas of groundwater contamination in Garvey's
Point which may eventually comingle with the Mattiace plume.
Therefore, the certainty of achieving cleanup goals at all points
throughout the plume may only be known after implementation and
operation of the pumping and treatment activity for a period of
time sufficient to ascertain cleanup effectiveness.

     o Short-term Effectiveness

Both the MOM-3 and the MOM-6 groundwater alternatives would take
approximately 2 years to design and construct.  In the short-
term, removal of the "floating product" layer, as well as the
significant removal of contamination from groundwater expected
initially upon implementation of either of the MOM alternatives
should result in a dramatic improvement in groundwater quality
over its currently degraded state.

Short-term impacts associated with construction and operation of
the various groundwater treatment alternatives should be minor
and easily minimized through appropriate health and safety
protocols during construction, as well as diligent operation and
maintenance practices once either of the MOM-3 or the MOM-6
alternatives is operational.

     o Long-term Effectiveness and Permanence

Both the MOM-3 and the MOM-6 groundwater alternatives would
involve treatment technologies, i.e. groundwater and free product
pumpage, air stripping, carbon adsorption, thermal treatment,
uv/peroxide oxidation, etc. that have been utilized previously at
other Superfund sites.  Based on the demonstrated effectiveness
of these technologies at other sites, these alternatives should
result in permanent, long-term effectiveness after the target
reductions of groundwater contamination have been reached.

-------
                                24

Preliminary groundwater modelling indicates that the time needed
to restore the groundwater degraded as a result of the Site to
its previous most beneficial use, i.e. a potential potable water
source, is approximately 30 years.   However, this estimate should
be qualified by the discussion under Compliance with ARARs above.
Since both the MOM-3 and the MOM-6  alternatives rely on an
optimized extraction and discharge  scenario, this estimate is the
same for both alternatives.

     o Reduction of Toxicity. Mobility, or Volume

Both the MOM-3 and the MOM-6 groundwater alternatives would
significantly reduce the volume and concentrations of
contaminants in the groundwater plume.  In addition, mobility of
the groundwater plume would be drastically reduced and perhaps
eliminated.  Therefore, both of the groundwater treatment
alternatives would eliminate the future risks associated with
non-carcinogenic toxicity of Site contaminants while reducing the
carcinogenic risk to acceptable levels through the attainment of
ARARs.  Low concentration soil/contaminant binding may occur
during extended pumping of groundwater such that groundwater
ARARS are difficult or impossible to achieve at the point of
compliance.  However, these ARARs correspond to a very low risk
level; therefore, if such a failure to obtain these requirements
through groundwater treatment were to occur, it is nevertheless
likely that either alternative would result in the reduction of
the future risk associated with ingestion and dermal contact to
within EPA's acceptable risk range.

     o Implementabilitv

EPA believes that both of the groundwater alternatives presently
under consideration are implementable in terms of the materials
and services that would be needed,  as well as from the standpoint
of administrative requirements or restrictions that presently
exist.

     o Cost

The relative costs of the groundwater remediation alternatives
are given below:

     Alternative   Capital Cost	O&M Cost   Present Worth Cost

     MOM-3          $3,316,921      $592,859      $12,430,350
     MOM-6          $5,663,820    $1,597,227      $30,216,393

As can be seen from the table, Alternative MOM-3 has a
significantly lower present worth cost than Alternative MOM-6.

     o State Acceptance

-------
                                25

The State of New York has reviewed and concurs with the selected
remedy (see State letter of concurrence- APPENDIX 3).

     o Community Acceptance

EPA concludes that the selected remedy has the support of the
affected community based on the comments received during the
public comment period, including those comments received during
the public meeting held on May 30, 1991.

SELECTED REMEDY

General

The selected remedy for the Site is a combination of sc-3b (In
Situ Vacuum Extraction of General Site Area Soils and Non-
Pesticide "Hot Spots"/ Excavation of Pesticide "Hot Spots" with
Off-Site Treatment and Disposal) and MOM-3 (Groundwater
Extraction/ Air Stripping/ Carbon Adsorption of Water Effluent/
Thermal Treatment of Air Effluent/ Reinjection of Treated
Groundwater).                                               '  .

Any hazardous non-regenerative residuals resulting from on-site
treatment will be disposed off-site in accordance with the
applicable/appropriate requirements of RCRA and State hazardous
waste laws and regulations.

The estimated cost for the selected remedy is:

     Capital Cost: $6,544,487
     Present Worth Cost: $15,930,592

A detailed description of costs associated with the selected
remedy is presented in TABLE 5.

Soil Remedy

The soil remediation aspect of the selected remedy will involve
in situ treatment of approximately 17,140 cy of contaminated soil
(including non-pesticide "hot spots") by means of vacuum
extraction, and excavation of approximately 208 cy of soil (which
includes excavation soil expansion factor) contaminated primarily
with pesticides for off-site treatment and disposal, in
accordance with applicable/appropriate requirements of RCRA and
State hazardous waste laws and regulations.  For costing
purposes, off-site treatment was assumed to be incineration,
although other more innovative technology may be eventually
selected on the basis of cost and treatment equivalence.

The in situ vacuum extraction system will be operated until soil
cleanup levels corresponding to EPA's target risk level of IxlO"6
are achieved.  The soil cleanup levels of selected indicator

-------
                                26

chemicals determined by EPA to correspond to a IxlO"6 risk level
are given below:

CHEMICAL                     CLEANUP LEVEL
                                (mg/kg)
Volatile Organics

Tetrachloroethylene              0.6
Trichloroethylene                0.07
4-Methyl-2-Pentanone            52.1
Xylene                         259

In addition, the excavation of the pesticide "hot spots" will be
intended to reduce residual pesticide contamination to the
following cleanup levels which correspond to a IxlO"6 risk level:


CHEMICAL                     CLEANUP LEVEL
                                (mg/kg)
Pesticides

Aldrin                           0.04
Alpha Chlordane                  0.5
Heptachlor Epoxide               0.07

In situ vacuum extraction of contaminated soils will involve the
removal of organic contaminants from the soil without major soil
disturbance, and is accomplished by installing soil vapor
extraction wells at strategic points, manifolding the wells, and
applying a vacuum in order to draw contaminated soil gases out of
the ground and into a treatment system.  For costing purposes,
EPA has estimated that 12 such wells will be needed; however, the
actual number and sizing of the wells will be determined during
the design phase of this project.   The treatment system for
extracted soil gases is comprised of a vapor/liquid separator and
an activated carbon canister, for off-gas emission control,
although equivalent technologies could be utilized.  The details
of the extracted soil gas treatment system will also be finalized
during design.  In addition, treatability studies will also be
performed to determine design parameters for the vacuum
extraction system (FIGURE 11).

EPA may also include the use of the vacuum/treatment technology
on VOC-contaminated stockpiles of soil from the general Site area
(not the Area 1 drum burial area,  which will be excavated for
off-site treatment and disposal in accordance with the second
operable unit ROD).   These stockpiles will be a result of EPA's
regrading the western part of the Site in order to increase the
stability of a retaining wall, which is scheduled to occur during
the second operable unit remedial action.

The excavation.of soils for off-site treatment and disposal will

-------
                               27

involve excavation of pesticide-contaminated "hot spots".
Approximately 208 cy of soils are expected to be removed from the
three areas that are contaminated with pesticides.

Clean fill will be used to backfill excavated areas. Contaminated
surface runoff associated with remedial activity at the Site,
particularly excavation of the pesticide-contaminated areas, will
be controlled through the use of covers, berms, etc.

The selected remedy will also include the decontamination (as
necessary), demolition, removal,  and landfill disposal of the
Quonset hut, 24 aboveground storage tanks, 32 underground storage
tanks, including the solvent/stormwater separator in the
southeast part of the property, and 1,360 cy of concrete and
asphalt.  Clean fill will be used to backfill excavated tank
areas.

Groundwater Remedy

The contaminated groundwater aspect of the selected remedy will
include extraction and injection wells installed into the
contaminated groundwater plume.  For costing purposes, EPA
estimates that 8 extraction wells will be required in order to
capture and remove the plume of contaminated groundwater.   First,
approximately 15,000 gallons of "floating product" beneath the
Site will be removed through the extraction wells with a skimmer
pump, with subsequent transportation of the extracted product
off-site for treatment and disposal.  Next, approximately 20,000
gallons per day of the contaminated groundwater plume will be
pumped out of the ground and into an equalization tank,
pretreated via precipitation and clarification to remove iron and
manganese  (these metals would interfere with subsequent
treatment), and then treated on-site by means of air stripping
technology to remove volatile organics.  The air effluent from
the air stripper will then be thermally treated prior to
discharge in order to meet the applicable/appropriate
requirements of the Clean Air Act and State laws and regulations.
The water effluent from the air stripper will be carbon-treated
in order to reduce any remaining organic contaminants to levels
below applicable/appropriate requirements of the Safe Drinking
Water Act  (maximum contaminant levels, or MCLs) and State laws
and regulations (10 NYCRR Part 5).

An example of some of the ARARs for groundwater remediation at
this Site are:

CHEMICAL                 REQUIREMENT     REFERENCE

Tetrachloroethylene      5 ug/1          10 NYCRR Part 5
Trichloroethylene        5 ug/1          40 CFR Parts 141 & 142
Ethylbenzene             5 ug/1          10 NYCRR Part 5
Total xylenes            5 ug/1          10 NYCRR Part 5

-------
                                28

Methylene Chloride       5 ug/1          10 NYCRR Part 5
o-Dichlorobenzene        5 ug/1          10 NYCRR Part 5

Spent activated carbon will be transported off-site and
regenerated for reuse.  The treated water effluent will then be
reinjected into the ground through groundwater reinjection wells
(For costing purposes, EPA estimates 4 reinjection wells).
Reinjection will take place hydraulically upgradient of -the
extraction zone in order to accelerate the rate of groundwater
treatment.  Actual spatial and depth locations of extraction and
reinjection wells will be determined from additional groundwater
monitoring to be conducted during the design phase of the project
(FIGURE 12).  During the design phase, EPA will also consider and
attempt to mitigate the possible impact that localized pumping
and reinjection may have on the wetland vegetation along the
Creek and in Garvey's Point Preserve, although the likelihood of
such impact is considered remote at the present time.

The goal of the groundwater portion of the selected remedy is to
restore groundwater under the Site to its most beneficial use,
which is as a potential supply of potable water.  Based on
information obtained during the RI and on a careful analysis of
remedial alternatives, EPA believes that the selected remedy will
achieve this goal.  It may become apparent, during implementation
or operation of the groundwater extraction system, that
contaminant levels have ceased to decline and are remaining
constant at levels higher than the remediation goal over some
portion of the contaminated plume.  In such a case, the system
performance standards arid/or the remedy may be reevaluated.

The selected remedy will include groundwater extraction for an
estimated period of 30 years, during which the system's
performance will be carefully monitored on a regular basis and
adjusted as warranted by the performance data collected during
operation.  Modifications may include any or all of the
following:

     - Discontinuing pumping at individual wells where cleanup
     goals have been attained

     - Alternating pumping at wells to eliminate stagnation

     - Pulse pumping to allow aquifer equilibration and to allow
     adsorbed contaminants to partition into groundwater

     - Installing additional extraction wells to facilitate or
     accelerate cleanup of the. contaminant plume

TABLE 6 provides a summary of the remediation goals for both soil
and groundwater at the Site.

Monitoring Program

-------
                               29

The selected remedy includes both a short-term monitoring
program, which is intended to assist in designing the selected
remedy through acquisition of additional remedy-specific
information, and a long-term monitoring program for evaluation of
the cleanup.  Ancillary programs for monitoring worker safety
during remedy design and construction are standard in the
Superfund program and do not require further elaboration.

The short-term monitoring program will include the following
elements:

     - groundwater monitoring to further define localized
     hydrologic gradients, as well as the extent of the Site
     groundwater plume.  This information will assist in the
     design of the groundwater extraction and reinjection system
     and will likely necessitate the construction of several new
     monitoring wells at strategic locations previously
     identified during the RI.

     - radiological monitoring during any excavation activities
     at the Site (as a precautionary measure due to the history
     of limited landfilling of radiological materials in the
     nearby Garvey's Point landfill).

     - treatability studies for the in situ vacuum extraction
     system, which will likely involve pilot scale testing and
     monitoring to ascertain design parameters that are
     associated with the soils on-site.

     - soil gas survey of the perimeter of the Mattiace property
     and beyond, as necessary, to determine whether appreciable
     amounts of contaminated soil gas are migrating off-site in  '
     the vadose zone.

     - additional sampling of soil and sediment along the surface
     runoff pathway from the Mattiace property to Glen Cove
     Creek, including the sediments, if any, in the storm sewer
     which discharges to the Creek.

The selected remedy also includes the following long-term
monitoring provisions:

     - a soil sampling program utilizing soil borings as needed
     to ascertain the progress of the in situ vacuum extraction
     soil cleanup.  Soil samples will be analyzed for, at a
     minimum, those organic compounds for which action levels
     have been specified as part of the selected remedy.  This
     program will be more fully developed during the construction
     of the in situ vacuum extraction system.

     - a semi-annual groundwater monitoring program to ascertain
     the progress of the pumping and treatment of groundwater.

-------
                                30

     Groundwater samples will be analyzed for, at a minimum, the
     contaminants of concern identified in the risk assessment
     contained in the risk assessment for the Site.  This program
     will be more fully developed during the construction of the
     groundwater pumping and treatment system.

     - an annual sampling program of Glen Cove Creek sediment and
     water column to determine any increase or decrease in the
     levels of contaminants in both media.  Samples will be taken
     in the three locations that were sampled during the first
     operable unit RI, and samples will be analyzed for, at a
     minimum, the contaminants of concern identified in the risk
     assessment for the Site.

As required by CERCLA, EPA will also conduct five year reviews of
the Site in order to ensure that public health and the
environment are adequately protected.

During the performance of long-term monitoring, EPA may determine
that a remedial action objective has been met.  At that point,
EPA may terminate any monitoring programs associated with that
objective.  For the long-term groundwater monitoring program,
however, EPA will continue to monitor on a semi-annual basis for
at least one year after cleanup levels are achieved and
groundwater extraction/treatment has ceased in order to ensure
that cleanup levels are maintained.  Upon meeting all remedial
objectives, or determining that the Site has been sufficiently
purged of contaminants so that public health is no longer
threatened by exposure to the Site, EPA will initiate proceedings
to delete the Site from the National Priorities List.

STATUTORY DETERMINATIONS

Under its legal authorities, EPA's primary responsibility at
Superfund sites is to undertake remedial actions that achieve
protection of human health and the environment.  In addition,
Section 121 of CERCLA establishes several other statutory
requirements and preferences.  These specify that, when complete,
the selected remedial action for a site must comply with
applicable or relevant and appropriate environmental standards
established under Federal and State environmental laws unless a
statutory waiver is justified.  A selected remedy also must be
cost effective and utilize permanent solutions and alternative
treatment technologies or resource recovery technologies to the
maximum extent practicable.  Finally, the statute includes a
preference for remedies that employ treatment that permanently
and significantly reduce the volume, toxicity, or mobility of
hazardous wastes as their principal element.

Protection of Human Health and the Environment

The selected remedy will result in the reduction of soil

-------
                                31

contaminants at the Site to health-based cleanup levels through
the use of in situ vacuum extraction and the excavation and
removal of three pesticide "hot spots" not amenable to the vacuum
extraction technology.  The selected remedy will also provide for
the cleanup of contaminated groundwater beneath the Site
(including removal of the concentrated "floating product" layer)
to existing ARARs, which are intended to protect human health by
assuring the quality of potable water supplies.  Although the
groundwater contaminated at this Site is not presently used for
potable water by the community, its most beneficial use according
to a classification made by the State of New York is as potable
water.  Therefore, EPA believes that the groundwater remedy
selected should address the aquifer's potential use as potable
water.  In addition, all existing above- and belowground storage
tanks will be decontaminated and removed off-site, thereby
eliminating any threats posed by residual contamination still
residing in the tanks.  Although some risks may be posed to. Site
workers during excavation and hazardous waste/residuals handling,
these risks can be easily mitigated through implementation of
appropriate health and safety precautions.

Compliance With Applicable or Appropriate and Relevant Standards

The selected remedy for source control (SC-3b: in Situ Vacuum
Extraction of General Site Area and Non-pesticide "Hot Spots"/
Excavation of Pesticide "Hot Spots" with Off-site Treatment and
Disposal) is expected to comply with all ARARs.  Any off-site
facility used for treatment and disposal will be fully RCRA-
permitted and will be in compliance with the terms of the permit.
Any contaminated soil, debris, or sediments from the Site will be
treated using specific technologies or specific treatment levels,
as appropriate, to comply with LDRs.  Any residuals from the
treatment processes that are non-regenerative will be treated and
disposed of in compliance with LDRs.

The selected groundwater remedy MOM-3 (Groundwater Extraction/
Air Stripping/ Carbon Adsorption of Water Effluent/ Thermal
Treatment of Air Effluent/ Reinjection of Treated Groundwater) is
expected to comply with the associated ARARs over time.  It may
become apparent, during implementation or operation of the
groundwater extraction system, that contaminant levels have
ceased to decline and are remaining constant at levels higher
than ARARs over some portion of the contaminated plume.  In such
a case, the system performance standards and/or the remedy may be
reevaluated.

At its completion, EPA intends that the selected remedy will
comply with, at a minimum, the following ARARs:

Cost Effectiveness

The selected remedy provides overall effectiveness proportional
to its cost.  The total capital and present worth costs for the
selected remedy are estimated to be $6,544,487 and $15,930,592,
respectively.  The selected soil alternative, 8C-3b, is the
second least expensive treatment alternative.  8C-3c is slightly
less costly to implement; however, the corresponding reduction in
protection of public health does not, in EPA's view, warrant its
selection.

The selected groundwater alternative, MOM-3, is the least
expensive treatment alternative.

                                33

Utilization of Permanent Solutions and Alternative Treatment
Technologies (or Resource Recovery Technologies)  to the Maximum
Extent Practicable and Preference for Treatment as a Principal
Element

The removal and subsequent permanent treatment of soil and
groundwater contaminants through the technologies of the selected
remedy satisfies the statutory preference of CERCLA for utilizing
permanent solutions and alternative treatment technologies to the
maximum extent practicable.  The selected remedy will also
permanently and significantly reduce the toxicity, mobility, and
volume of hazardous substances in both the soil and groundwater
at the Site, thereby eliminating all the principal threats of
contamination at the Site.

DOCUMENTATION OF SIGNIFICANT CHANGES

The Proposed Plan for the Site was released to the public in May
1991.  The Proposed Plan identified a combination of SC-3b and
MOM-3 as the preferred alternative to remediate the source of
contamination.   EPA reviewed all comments submitted during the
public comment period.  Upon review of these comments, it was
determined that no significant changes to the selected remedy, as
it was originally identified in the Proposed Plan, were
necessary.

                    RESPONSIVENESS SUMMARY

                 MATTIACE  PETROCHEMICAL CO.,  INC.
                  GLEN COVE,  NASSAU COUNTY, N.Y.

The U.S. Environmental Protection Agency (EPA) scheduled a public
comment  period  from  May  15,   1991  through  June  14,  1991  for
interested parties to  comment on EPA's final Feasibility Study (FS)
and  Proposed  Plan for  the  first operable  unit at  the  Mattiace
Petrochemical Co., Inc.  Site. EPA held a public meeting on May 30,
1991 at  the Glen Cove City  Hall, located on Bridge Street,  Glen
Cove, N.Y. to  describe the remedial alternatives and present EPA's
Proposed Plan for addressing the first operable unit objectives at
the Site.

A  transcript  of  the  meeting is  included in  the  Administrative
Record file for  the Site  and documents  those questions addressed
and EPA's responses at the public meeting. Other comments received
during the comment period,  as well as  those comments made during
the  public meeting,  are  summarized and  responded  to  in  this
responsiveness summary.  All"comments were considered prior to the
selection of the remedy for the Mattiace Petrochemical Co.,  Inc.
Site.
      *           *           *          *            *

The following  are further responses  to  comments expressed at the
May 30, 1991 public meeting:

Comment:   Is  the Site  made up  of fill,  and if so, what  is its
source?

Response:    The  Site  appears   to   conform   to  the  surrounding
topography in the area,  and therefore the existing Site grade does
not  appear  to be  the result of extensive  filling.  EPA  is not
presently aware of any locations on the Site  that have been filled
with material that originated offsite.

Comment:  What other constituents comprised the  "floating product"
in the groundwater? The reported levels in the RI only account for
a small amount of the total  mass of floating product.

Response:   The  concentrations  of  organic  chemicals that  were
analyzed for in  the "floating product"  samples taken by EPA were
reported in Appendix A-5 of the Remedial Investigation Report.  The
TCL volatile organic  parameters were erroneously reported in the
units "ug/kg"  instead of the correct  "mg/kg"  units.  The corrected
pages of Appendix A-5 are attached to this Responsiveness Summary
as ATTACHMENT 1.   Based on the reported (corrected) concentrations
of TCL volatile  constituents, .these constituents comprise between
approx. 38-58% of the  "floating product" mass.  The remaining mass,
which  was  not   analytically   identified,   may   be  emulsified
groundwater.

Comment:  Clarify the State's  jurisdiction  in regard to potable

-------
water permitting.

Response:   The  State  of  New  York presently  does not  regulate
groundwater withdrawals rated at less than 40 gallons per minute.
However,  the  New York  State Department  of Health does  require
registration  (without  further   regulation)  of  all  groundwater
withdrawals regardless of withdrawal rate.

Comment:  Did  you investigate the existence of private wells in the
area?

Response:  EPA did a survey of all residential and industrial wells
within  a  one-half mile  radius  of the Site.  A total  of  20 wells
were located  based  on  the records of NYSDEC and NYSDOH,  and the
results are reported in the April, 1989 workplan for the Site (page
3-18).  Based on the survey,  there are only three wells that could
conceivably be affected by the groundwater contamination from the
Site because  of  their  proximity to and direction  from  the Site.
However, the three wells, Well # 4440 (LIMCO Corp.), and Wells 8690
and  8709D (Fabric Leather Corp.), are all  screened  in  the Lloyd
Aquifer, which is not hydraulically connected to the contaminated
aquifer under investigation.

Comment:   Some  of  the  New  York State drinking water  standards
contained in the FS report are not correct.

Response:   The  standards specified in  Table 2-1 of  the  FS were
reviewed  and  commented  on by the New York  State  Departments of
Environmental Conservation and Health.  At the present  time, EPA
considers  the respective State  Agency's  approval  regarding the
standards   as .properly  reflective  of   all  applicable  State
regulations.

Comment:   Could the removal of  the "floating product"  layer be
performed  earlier  than  what  was  presented,  during  the  public
meeting?

Response:   EPA presently  estimates  that the removal of  "floating
product" will begin  in mid-1993 and  take approximately one year to
complete.  This estimate assumes  that certain administrative steps
involving program enforcement occur and are followed by a design
for  the groundwater  remedy to  be completed  by mid-1993.   At the
present time,  EPA has already examined in a preliminary fashion the
possibility of rapidly commencing "floating product" removal after
consideration of certain enforcement  alternatives.   Because of
several  technical problems  associated with this  approach,  EPA
believes that the completion of the groundwater design phase will
be necessary prior to implementing the "floating product" removal.
However, at the commencement of the groundwater design phase, EPA
will further  examine possible ways of initiating  the  "floating
product" removal prior to completion of design.

-------
Comment:  What's the status of the drum removal (OU 2)?

Response:    The drum  removal,  which  was  the  selected  remedy
contained in  the 2nd operable unit  Record  of Decision  for  this
Site, is presently underway.  LILCO provided power line rerouting
services  the week  of  June  17th,  which was  necessary prior  to
commencement of actual  drum excavation and removal.  EPA estimates
that 4 months will be required (commencing with the LILCO activity)
before  all  the  excavated  materials  are removed  from the  Site.
However,  actual excavation  and  staging  of hazardous  materials
should take only 2-4 weeks.

Comment:  Are the Sea Cliff Well and the Glen Cove Wells which were
mentioned in the public meeting presentation being affected?

Response:  As indicated during the presentation,  based on the RI,
neither  well(field) has  the  potential to  be affected by  the
Mattiace groundwater plume because of their locations relative to
the plume.  The  Glen Cove Wells are located approximately two miles
upgradient of the Site,  while the Sea  Cliff Well, while closer, is
away from the projected path of the plume.   The Sea Cliff Well is
also  screened  in   the  Lloyd  Aquifer,   which  is  not  connected
hydraulically with the Upper Glacial Aquifer in that area.

          ******
The following are responses to comments submitted by ERM-Northeast,
on behalf of 20 Garvey's Point  Road  Corporation,  transmitted on
June 14, 1991.

Comment:  Selection of  New York  State Sanitary Code standards as
ARARs may adversely impact  the ability  of the  selected remedy to
achieve its goal because of the  extremely  high concentrations of
organics  in  groundwater,  as well  as  the presence of  a  separate
(lighter) phase  of  organic  contamination, which will continue to
contaminate the groundwater below it.

Response:   EPA  recognizes that  the  ARARs  for this  Site  will be
difficult to attain in  all  areas  of groundwater contamination (see
ROD  discussion,  page 22),  because of the high concentrations of
groundwater contaminants.  However, as part of the selected remedy,
EPA will effectively remove all  hazardous  substances at the Site
which might  act  as sources of continuing  groundwater contamination.
The selected remedy will include  removal of the "floating product"
layer, as well  as  all  underground tanks and containment vessels,
e.g. the solvent/stormwater separator.  It will also include soil
remediation, so that all sources  of groundwater contamination will
be addressed.  Therefore, any difficulty which may be encountered
in reaching  selected ARARs  for  this Site will be as a  result of the
factors  cited  in  the  ROD  discussion,   and  not  as  a result  of
leaching of contaminant sources  into the groundwater.

Comment:  Why isn't groundwater cleanup of inorganic constituents

-------
to ARARs being pursued?

Response:   The maximum  groundwater concentrations of  inorganic
constituents of concern i.e., manganese and beryllium, found at the
Mattiace Site are  given in Table 2-1 of the FS Report.  The maximum
detected concentration of  beryllium is within both the  ARAR and
risk assessment action levels.   On the other hand, the maximum
detected concentration of manganese exceeds the applicable New York
State ARAR.  This ARAR is  a secondary (aesthetic)  drinking water
standard related  to  taste,  rather  than a  primary  health-related
standard.  Both manganese and iron will be removed from groundwater
during the pretreatment  process which  is  part of the groundwater
selected remedy.  Further,  the risk assessment indicates that the
present  maximum  concentrations  of manganese  do  not  pose  an
unacceptable risk to public health or the environment.

Comment:   The proposed groundwater  remedy  of  extraction  and
reinjection may move high concentrations of contaminants into areas
not presently affected by these chemicals or levels.

Response:   The recovery and  reinjection system  which will: be
designed as  part  of the  selected remedy  will strive  to  be  a
"closed" system, i.e.  groundwater contaminants will be effectively
contained from further migration.  The long-term monitoring program
contained in the ROD will assist in  determining whether the remedy
is  successful  in this  regard.    Future modifications to  the
constructed remedy,  e.g.  additional  recovery or reinjection wells,
could be effected at a later date if indicated by the monitoring.

Comment:   The proposed  groundwater remedy will probably  not be
successful since the RI did not adequately  define certain essential
hydrological and contaminant parameters. Therefore, a supplemental
RI should be undertaken  to  develop  required information prior to
selection of a groundwater remedy.

Response:  EPA does  not  believe that  a second  operable  unit for
groundwater  is the  proper response  to   the  information  needs
identified in the  remedial  investigation.  EPA believes sufficient
information is available  to  select this remedy.  Pre-design studies
will be  undertaken  to further develop the data  base  required to
implement the  selected groundwater  remedy,  including calculating
the  proper numbers  and  placements  of groundwater  recovery and
reinjection wells.  Since community relations is an integral part
of all phases of a Superfund project, the results of the pre-design
studies will be made available to the public after completion.

Comment:  Additional surface soil sampling should be performed on
the  former  Edmos property to  assess the possible  impact  of
contaminated stormwater  runoff on that property.

Response:   In the selected remedy, EPA has  included  additional
sampling  of  soil and   sediment  along the  documented  surface/

-------
stormwater sewer runoff pathway from the Mattiace property to Glen
Cove Creek,  including  the sediments,  if any,  in  the storm sewer
which  discharges to  the Creek.    This  pathway may technically
include parts  of the former Edmos  property,  such  as the unpaved
"common driveway" area  between the Mattiace gate and Garvey's Point
Road.
[N.B.:  At the public meeting (and recorded in the public meeting
transcript), the Remedial Project Manager was quoted as saying that
the present worth cost  estimate  for  the proposed remedy is $11.2
million.   The quoted present worth  estimate was  in error.   The
correct  present worth  cost estimate  is  $15.9  million,  as  was
indicated in the Proposed Plan.]
