Jim
O'Leary
and
Teena
Wooten
with
the
Environmental
Protection
Agency's
Office
of
Solid
Waste
toured
the
McArdle
facility
in
Upper
Marlboro,
Maryland
on
April
13,
2006.
The
visit
began
with
a
general
discussion
of
the
plant
operations
and
its
use
of
wipes.

McArdle
employs
approximately
210
people
and
is
considered
a
large
printer.
The
shop
has
a
total
of
eight
presses;
two
six­
color
sheet­
fed
presses
with
automatic
washing
features;
a
twocolor
sheet­
fed
press;
a
four­
color
sheet­
fed
press;
and
four
web
presses.
The
sheet­
feds
and
one
four­
unit
web
are
run
at
almost
90%
capacity.
The
other
webs
run
somewhat
less.
One
twocolor
web
runs
about
70%
of
capacity,
another
two­
color
web
only
runs
about
30%
of
the
time;
one
older
four­
unit
web
runs
about
25%
of
the
year.

Depending
on
the
workload,
the
facility
now
uses
between
2,200
and
3,000
wipes
a
week.
The
number
of
wipes
used
before
the
year
2001
is
not
known.

McArdle
uses
mostly
Powerclean
VC
to
clean
its
presses.
This
solvent
is
a
rejuvenator.
It
has
a
flash
point
of
114o
F,
and
a
boiling
point
of
316o
F.
Approximately
100
gallons
of
the
material
is
used
per
week
for
all
eight
presses.
Since
2001,
the
facility
has
seen
an
increase
in
solvent
usage.
At
that
time,
McArdle
added
another
six­
color
sheet­
fed
press.
The
company
now
has
two
six­
color
sheet­
fed
presses
with
automatic
blanket
washers.
Automatic
washers
increase
solvent
use,
but
decrease
time
spent
cleaning
and
wipe
use
per
press.

Solvent
is
used
in
roller
and
blanket
washing.
Two
of
the
presses,
the
six­
color
sheet­
feds,
have
automated
self­
cleaning
features.
The
remaining
two
sheet­
fed
and
four
web
presses
do
not
have
automatic
cleaning
features
and
must
be
washed
by
hand.
To
clean
the
presses
with
the
automatic
cleaning
features,
solvent
and
water
are
injected
on
the
blanket
washer
as
it
runs
its
blanket
cleaning
cycle.
The
excess
waste
solvent
mixture
is
drained
to
a
single
location
in
a
fivegallon
waste
container
on
the
side
of
the
press.
It
is
then
poured
into
55­
gallon
waste
drums.
An
estimated
95%
of
the
solvent
waste
is
generated
by
these
two
presses.
Wipes
are
used
only
on
the
back
cylinders,
ink
trays,
and
final
touch­
ups
on
blankets.

Manual
washing
is
accomplished
by
the
press
operator
applying
solvent
to
a
wipe
and
washing
down
the
press,
blankets,
and
back
cylinders.
When
a
wipe
is
dirty
and
can
no
longer
be
used,
it
is
placed
in
a
drum
with
a
screen
on
the
bottom.
The
solvent
collected
in
the
drum
is
sent
offsite
for
disposal.
This
accounts
for
about
5%
of
the
solvent
waste.
The
used
wipes
are
collected
and
sent
to
a
laundry
weekly.
Approximately
14
drums
total
of
solvent
waste
are
generated
each
six­
week
period.
The
waste
mixture
is
approximately
40%
water
and
60%
Powerclean
VC.
These
drums
are
sent
off­
site
for
disposal.

During
the
site
visit,
Jim
O'Leary
weighed
several
wipes.
A
dry
wipe
weighed
63.8
grams.
Contaminated
wipes
were
selected
from
the
top,
near
the
middle,
and
near
the
bottom
of
the
drum.
The
wipes
ranged
in
weight
from
94.7
grams
and
121.5
grams
on
the
top,
from
102.7
grams,
113
grams,
and
103.4
grams
close
to
the
middle,
and
119.1
grams,
100.9
grams
and
98.8
grams
closer
to
the
bottom.
The
heavier
wipes
had
more
ink
on
them.

The
visit
concluded
with
a
brief
discussion
on
the
overall
observations
and
requests
for
additional
information.
