SITE
SUMMARY
The
Diamond
Head
Oil
Refinery
Div.
(Diamond
Head)
site
is
located
at
1401
Harrison
Ave.
in
Kearny,
Hudson
County,
New
Jersey.
Currently,
the
site
is
inactive
and
consists
of
undeveloped
land
that
is
bordered
by
Harrison
Avenue
to
the
north,
entrance
ramp
M
of
Interstate
280
(I­
280)
to
the
east,
I­
280
to
the
south,
and
Campbell
Distribution
Foundry
to
the
west.
The
site
is
comprised
of
wetland
areas
and
drainage
ditches,
a
small
wetland/
pond,
a
vegetated
landfill
area
along
the
western
border
of
the
site,
and
the
remnants
of
the
former
Diamond
Head
Oil
Refinery
on
the
eastern
portion
of
the
site.
The
abandoned
refinery
portion
of
the
site
contains
various
construction
debris,
including
foundations
of
the
former
on­
site
building
and
two
former
aboveground
storage
tanks.
The
refinery
is
currently
owned
by
the
Hudson
Meadows
Urban
Land
Development
Corporation
(HMULDC).

The
Diamond
Head
Oil
Refinery
Div.
was
in
operation
from
February
1,
1946
to
early
1979.
The
facility
operated
under
several
company
names
including
PSC
Resources,
Inc.,
Ag­
Met
Oil
Service,
Inc.,
and
Newtown
Refining
Corporation.
All
of
these
companies
were
owned
by
Mr.
Robert
Mahler.
In
January
1985,
Newtown
Refining
Corporation
sold
the
property
to
Mimi
Urban
Development
Corporation,
which
changed
its
name
to
Hudson
Meadows
Urban
Land
Development
Corporation.
The
refinery
portion
of
the
site
is
currently
owned
by
HMULDC.

During
facility
operations,
two
aboveground
storage
tanks
(conflicting
reports
of
volumes
of
30,000
and
100,000
gallons)
and
possibly
underground
pits
were
used
to
store
oily
wastes.
These
wastes
were
intermittently
discharged
directly
to
adjacent
properties,
including
the
wetland
area
to
the
south
of
the
refinery,
creating
an
oil
lake.
The
New
Jersey
Department
of
Transportation
(NJDOT)
acquired
the
property
south
of
the
site
on
March
6,
1968.
In
1977,
NJDOT
began
construction
of
I­
280
and
was
reported
to
have
removed
9
million
gallons
of
oilcontaminated
water
and
5
to
6
million
cubic
yards
of
oily
sludge
from
the
lake.
The
material
was
reportedly
transported
to
Newtown
Refining
Corporation's
facility
on
Long
Island
to
be
recycled;
however,
there
are
no
reports
stating
that
this
recycling
process
occurred.
It
is
also
reported
that
during
the
construction
of
I­
280,
an
underground
lake
of
oil­
contaminated
groundwater
was
found
extending
from
the
eastern
limits
of
the
NJDOT
right­
of­
way
to
Frank's
Creek
on
the
west.
It
is
reported
that,
prior
to
abandoning
the
refinery,
Diamond
Head
cleaned
out
the
two
aboveground
tanks;
however,
there
is
no
known
documentation
of
this
activity.
From
the
close
of
operations
in
1979
until
1982,
the
abandoned
refinery
was
not
completely
fenced.
During
this
time,
it
was
reported
that
dumping
of
waste
oils
and
other
debris
took
place
on
site.
A
contractor
was
hired
to
clean
up
the
refinery
in
May
1982.
In
order
to
do
so,
the
material
in
the
tanks
was
analyzed
and
found
to
contain
polychlorinated
biphenyls
(PCBs)
at
a
concentration
of
206
parts
per
million
(ppm).
Subsequent
analyses
revealed
the
presence
of
PCBs
at
concentrations
over
3,100
ppm.
Approximately
7,500
gallons
of
material
were
reportedly
pumped
out
of
the
tanks
and
disposed
off
site
by
a
Resource
Conservation
and
Recovery
Act
(RCRA)
permitted
Treatment,
Storage,
and
Disposal
Facility
(TSDF).
In
addition,
27
tons
of
contaminated
soil
were
reportedly
removed
from
the
site
in
May
1982.

Background
information
indicates
that
previous
investigations
have
been
conducted
at
the
Diamond
Head
Oil
Refinery
Div.
site.
These
investigations
include
a
sampling
event
conducted
by
the
New
Jersey
Department
of
Environmental
Protection
(NJDEP),
an
Environmental
Site
Characterization
conducted
by
a
contractor
hired
by
HMURDC,
and
a
Site
Inspection
conducted
by
the
U.
S.
Environmental
Protection
Agency
(EPA)
Region
II
Field
Investigation
Team
(FIT).
During
these
investigations,
groundwater,
surface
water/
sediment,
surface/
subsurface
soil,
liquid
waste
and
solid
waste
samples
were
collected.
Analytical
results
of
these
samples
indicated
the
presence
of
volatile
organic
compounds
(VOCs),
and
semivolatile
organic
compounds
(SVOCs),
pesticides,
PCBs,
and
metals.

In
December
1999
EPA
conducted
an
Expanded
Site
Inspection
(ESI)
at
the
Diamond
Head
Oil
Refinery
Div.
site.
During
the
ESI,
EPA
collected
surface/
subsurface
soil
and
ground
water
samples
from
20
borings
advanced
throughout
the
site.
EPA
also
collected
sediment
samples
from
the
on­
site
wetland/
pond
area
as
well
as
from
the
wetland
area
extending
along
the
southern
perimeter
of
the
site.
Analytical
results
indicated
the
presence
of
VOCs,
SVOCs,
pesticides,
PCBs,
and
metals.

An
observed
release
to
surface
water
is
documented
by
chemical
analyses
of
sediment
samples
collected
from
wetlands
along
the
southern
and
western
boundaries
of
the
site.
Level
II
concentrations
of
lead,
mercury,
and
zinc
are
documented
to
0.20
mile
of
wetland
frontage
extending
along
the
southern
and
western
boundaries
of
the
site.

were
discharged
directly
to
adjacent
properties
(including
the
wetland
area
in
the
southern
portion
of
the
site)
forming
the
oil
lake
(Ref.
4,
p.
5).
The
New
Jersey
Department
of
Transportation
(NJDOT)
acquired
the
property
adjacent
to
the
site
in
1968.
In
1977,
NJDOT
began
construction
of
Interstate
280
and
reportedly
pumped
approximately
9
million
gallons
of
oil
and
oil/
water
emulsion
from
the
lake.
In
addition,
approximately
200,000
to
250,000
cubic
yards
of
oil
sludge
were
removed
from
the
lake
by
mudwaving
and
backfilling
with
compressed
sand
(Ref.
4,
p.
5;
5,
p.
2;
Support
Document
for
the
Revised
National
Priorities
List
Final
Rule
February
2002).

Analytical
results
of
the
oil
lake's
oil
layer
indicated
32
percent
oil
and
68
percent
water
and
sediment.
In
addition,
the
sample
indicated
a
high
lead
and
zinc
content
(Ref.
5,
p.
3).
In
addition,
soil/
sediment
samples
collected
from
Wetland
A
during
the
1991
SI
indicated
the
presence
of
VOCs
(Ref.
4,
pp.
16,
17).

During
ESI
activities
conducted
by
EPA
in
December
1999,
petroleum
odors,
oil
saturated
soil,
and
free
product
were
observed
in
several
borings
advanced
in
the
area
of
the
former
oil
lake
(Ref.
11,
pp.
13,
14,
Figure
3).

A
review
of
aerial
photographs
indicate
that
the
area
of
the
on­
site
pond/
wetland
(wetland
A)
was
a
part
of
the
oil
lake
surface
impoundment
(Ref.
6,
p.
5).
Based
on
the
fact
that
this
area
was
an
isolated
water
body
and
was
intended
to
be
used
as
a
waste
management
area,
and
the
fact
that
hazardous
substances
in
the
pond
were
the
result
of
deposition,
the
on­
site
pond
is
evaluated
as
part
of
the
oil
lake
surface
impoundment.

The
oil
lake
is
not
excluded
as
a
source
at
the
site
due
to
the
fact
that
contaminants
not
associated
with
petroleum
products
(i.
e.,
PCBs,
chlorinated
solvents)
were
detected
in
samples
collected
from
the
oil
lake.
In
addition,
the
oil
lake
consists
of
waste
oils
and
is
not
the
result
of
a
petroleum
product
spill
(Ref.
5;
12).

Location
of
the
source,
with
reference
to
a
map
of
the
site:

The
former
oil
lake
was
located
in
the
southeast
portion
of
the
site
and
extended
off
site
to
the
south
and
east
(see
Figure
3).
A
portion
of
the
oil
lake
appears
to
have
existed
in
the
area
of
Wetland
A,
which
is
an
on­
site
palustrine
wetland
(Wetland
A)
located
in
the
southeast

of

(Ref.

lead,
mercury,
and
zinc
at
concentrations
significantly
above
the
background
concentrations
(Ref.
7,
pp.
53,
54,
56,
57).
Background
samples
were
collected
from
an
off­
site
wetland
which
was
deemed
not
affected
by
past
activities
at
the
Diamond
Head
Oil
Refinery
Div.
site
(Ref.
11,
pp.
6,
16).
Background
sediment
samples
were
collected
from
a
wetland
which
had
similar
vegetation
indicative
of
palustrine
emergent
wetlands.
This
wetland
was
similar
in
appearance
to
Wetland
A
and
Wetland
C,
which
are
both
palustrine
emergent
wetlands
located
on
the
Diamond
Head
Oil
Refinery
property.
Background
and
contaminated
sediment
samples
were
similar
in
sediment
type
and
percent
moisture.
Background
samples
and
contaminated
samples
were
both
collected
utilizing
the
same
sampling
procedures.
In
addition,
both
background
and
contaminated
sediment
samples
were
analyzed
for
TCL
and
TAL
contaminants
through
the
U.
S.
EPA
Contract
Laboratory
Program
(Ref.
15).
See
Figure
3
for
the
locations
of
wetland
sediment
samples.

The
observed
release
indicated
by
sediment
sample
data
constitutes
Level
II
contamination
of
approximately
0.20
mile
of
wetland
(Ref.
11,
pp.
17).
The
remainder
of
the
wetland
outside
of
those
sample
locations,
which
has
a
frontage
of
approximately
600
feet
(0.11
mile),
is
evaluated
under
potential
contamination
(Ref.
13).
Based
on
the
fact
that
there
is
no
information
to
support
if
Wetland
C
is
in
perennial
connection
with
Frank's
Creek
at
this
time,
Wetland
C
is
being
evaluated
as
an
isolated
wetland.

Attribution:

Background
information
indicates
that
oily
wastes
were
discharged
directly
to
adjacent
properties
(including
the
wetland
area
in
the
southern
portion
of
the
site)
forming
the
oil
lake
(Ref.
4,
p.
5).
Analytical
results
of
the
oil
lake's
oil
layer
indicated
32
percent
oil
and
68
percent
water
and
sediment.
In
addition,
the
sample
indicated
a
high
lead
and
zinc
content
(Ref.
5,
p.
3).

During
ESI
activities
conducted
by
EPA
in
December
1999,
petroleum
odors,
oil
saturated
soil,
and
free
product
were
observed
in
several
borings
advanced
in
the
area
of
the
former
oil
lake
(Ref.
11,
pp.
13,
14,
Figure

Analytical
results
from
sediment
samples
collected
from
the
on­
site
wetland
(i.
e.,
wetland
A),
which
is
believed
to
have
been
a
part
of
the
oil
lake,
indicated
concentrations
of
lead
up
to
84,300J
mg/

mercury
up
to
3.9

and
zinc
up
to
17,700J

Inspections
conducted
by
the
New
Jersey
Department
of
Environmental
