SCOPE
AND
APPLICATION
1.1
This
method
is
used
to
determine
whether
a
waste
exhibits
the
characteristic
of
Extraction
Procedure
Toxicity.

1.2
The
procedure
may
also
be
used
to
simulate
the
leaching
which
a
waste
may
undergo
if
disposed
of
in
a
sanitary
landfill.
Method
1310
is
applicable
to
liquid,
solid,
and
multiphase
samples.

2.0
SUMMARY
OF
METHOD
2.1
If
a
representative
sample
of
the
waste
contains
>
0.5%
solids,
the
solid
phase
of
the
sample
is
ground
to
pass
a
9.5
mm
sieve
and
extracted
with
deionized
water
which
is
maintained
at
a
pH
of
5
+
0.2,
with
acetic
acid.
Wastes
that
contain
<
0.5%
filterable
solids
are,
after
filtering,
considered
to
be
the
EP
extract
for
this
method.
Monolithic
wastes
which
can
be
formed
into
a
cylinder
3.3
cm
(
dia)
x
7.1
cm,
or
from
which
such
a
cylinder
can
be
formed
which
is
representative
of
the
waste,
may
be
evaluated
using
the
Structural
Integrity
Procedure
instead
of
being
ground
to
pass
a
9.5­
mm
sieve.

INTERFERENCES
3.1
Potential
interferences
that
may
be
encountered
during
analysis
are
discussed
in
the
individual
analytical
methods.

APPARATUS
AND
MATERIALS
4.1
Extractor
­
For
purposes
of
this
test,
an
acceptable
extractor
is
one
that
will
impart
sufficient
agitation
to
the
mixture
to
(
1)
prevent
stratification
of
the
sample
and
extraction
fluid
and
(
2)
ensure
that
all
sample
surfaces
are
continuously
brought
into
contact
with
well­
mixed
extraction
fluid.
Examples
of
suitable
extractors
are
shown
in
Figures

­
Filter
membrane
suitable
for
conducting
the
required
filtration
shall
be
fabricated
from
a
material
that
(
1)
is
not
physically
changed
by
the
waste
material
to
be
filtered
and
(
2)
does
not
absorb
or
leach
the
chemical
species
for
which
a
waste's
EP
extract
will
be
analyzed.
Table

lists
filter
media
known
to
the
Agency
to
be
suitable
for
solid
waste
testing.

4.4.1
In
cases
of
doubt
about
physical
effects
on
the
filter,
contact
the
filter
manufacturer
to
determine
if
the
membrane
or
the
prefilter
is
adversely
affected
by
the
particular
waste.
If
no
information
is
available,
submerge
the
filter
in
the
waste's
liquid
phase.
A
filter
that
undergoes
visible
physical
change
after
48
hours
(
i.
e.,
curls,
dissolves,
shrinks,
or
swells)
is
unsuitable
for
use.

4.4.2
To
test
for
absorption
or
leaching
by
the
filter:

4.4.2.1
Prepare
a
standard
solution
of
the
chemical
species
of
interest.

4.4.2.2
Analyze
the
standard
for
its
concentration
of
the
chemical
species.

4.4.2.3
Filter
the
standard
and
reanalyze.
If
the
concentration
of
the
filtrate
differs
from
that
of
the
original
standard,
then
the
filter
membrane
leaches
or
absorbs
one
or
more
of
the
chemical
species
and
is
not
usable
in
this
test
method.

PROCEDURE
7.1
If
the
waste
does
not
contain
any
free
liquid,
go
to
Step
7.9.
If
the
sample
is
liquid
or
multiphase,
continue
as
follows.
Weigh
filter
membrane
and
prefilter
to
+
0.01
g.
Handle
membrane
and
prefilters
with
blunt
curved­
tip
forceps
or
vacuum
tweezers,
or
by
applying
suction
with
a
pipet.

7.2
Assemble
filter
holder,
membranes,
and
prefilters
following
the
manufacturer's
instructions.
Place
the
0.45­
µ
m
membrane
on
the
support
screen
and
add
prefilters
in
ascending
order
of
pore
size.
Do
not
prewet
filter
membrane.

7.3
Weigh
out
a
representative
subsample
of
the
waste
(
100
g
minimum).

7.4
Allow
slurries
to
stand,
to
permit
the
solid
phase
to
settle.
Wastes
that
settle
slowly
may
be
centrifuged
prior
to
filtration.

7.5
Wet
the
filter
with
a
small
portion
of
the
liquid
phase
from
the
waste
or
from
the
extraction
mixture.
Transfer
the
remaining
material
to
the
filter
holder
and
apply
vacuum
or
gentle
pressure
(
10­
15
psi)
until
all
liquid
passes
through
the
filter.
Stop
filtration
when
air
or
pressurizing
gas
moves
through
the
membrane.
If
this
point
is
not
reached
under
vacuum
or
gentle
pressure,
slowly
increase
the
pressure
in
10­
psi
increments
to
75
psi.
Halt
filtration
when
liquid
flow
stops.
This
liquid
will
constitute
part
or
all
of
the
extract
(
refer
to
Step
7.16).
The
liquid
should
be
refrigerated
until
time
of
analysis.

NOTE:
Oil
samples
or
samples
containing
oil
are
treated
in
exactly
the
same
way
as
any
other
sample.
The
liquid
portion
of
the
sample
is
filtered
and
treated
as
part
of
the
EP
extract.
If
the
liquid
portion
of
the
sample
will
not
pass
through
the
filter
(
usually
the
case
with
heavy
oils
or
greases),
it
should
be
carried
through
the
EP
extraction
as
a
solid.

7.6
Remove
the
solid
phase
and
filter
media
and,
while
not
allowing
them
to
dry,
weigh
to
+
0.01
g.
The
wet
weight
of
the
residue
is
determined
by
calculating
the
weight
difference
between
the
weight
of
the
filters
(
Step
7.1)
and
the
weight
of
the
solid
phase
and
the
filter
media.

7.7
The
waste
will
be
handled
differently
from
this
point
on,
depending
on
whether
it
contains
more
or
less
than
0.5%
solids.
If
the
sample
appears
to
have
<
0.5%
solids,
determine
the
percent
solids
exactly
(
see
Note
below)
by
the
following
procedure:

7.7.1
Dry
the
filter
and
residue
at
80
E
C
until
two
successive
weighings
yield
the
same
value.

7.7.2
Calculate
the
percent
solids,
using
the
following
equation:

NOTE:
This
procedure
is
used
only
to
determine
whether
the
solid
must
be
extracted
or
whether
it
can
be
discarded
unextracted.
It
is
not
used
in
calculating
the
amount
of
water
or
acid
to
use
in
the
extraction
step.
Do
not
extract
solid
material
that
has
been
dried
at
80
E
C.
A
new
sample
will
have
to
be
used
for
extraction
if
a
percent
solids
determination
is
performed.

7.8
If
the
solid
constitutes
<
0.5%
of
the
waste,
discard
the
solid
and
proceed
immediately
to
Step
7.17,
treating
the
liquid
phase
as
the
extract.

7.9
The
solid
material
obtained
from
Step
7.5
and
all
materials
that
do
not
contain
free
liquids
shall
be
evaluated
for
particle
size.
If
the
solid
material
has
a
surface
area
per
g
of
material
>
3.1
cm2
or
passes
through
a
9.5­
mm
(
0.375­
in.)
standard
sieve,
the
operator
shall
proceed
to
Step
7.11.
If
the
surface
area
is
smaller
or
the
particle
size
larger
than
specified
above,
the
solid
material
shall
be
prepared
for
extraction
by
crushing,
cutting,
or
grinding
the
material
so
that
it
passes
through
a
9.5­
mm
(
0.375­
in.)
sieve
or,
if
the
material
is
in
a
single
piece,
by
subjecting
the
material
to
the
"
Structural
Integrity
Procedure"
described
in
Step
7.10.

7.10
Structural
Integrity
Procedure
(
SIP)

7.10.1
Cut
a
3.3­
cm
diameter
by
7.1­
cm
long
cylinder
from
the
waste
material.
If
the
waste
has
been
treated
using
a
fixation
process,
the
waste
may
be
cast
in
the
form
of
a
cylinder
and
allowed
to
cure
for
30
days
prior
to
testing.

7.10.2
Place
waste
into
sample
holder
and
assemble
the
tester.
Raise
the
hammer
to
its
maximum
height
and
drop.
Repeat
14
additional
times.

7.10.3
Remove
solid
material
from
tester
and
scrape
off
any
particles
adhering
to
sample
holder.
Weigh
the
waste
to
the
nearest
0.01
g
and
transfer
it
to
the
extractor.

7.11
If
the
sample
contains
>
0.5%
solids,
use
the
wet
weight
of
the
solid
phase
(
obtained
in
Step
7.6)
to
calculate
the
amount
of
liquid
and
acid
to
employ
for
extraction
by
using
the
following
equation:

W
=
W
f
­
W
t
where
:

W
=
Wet
weight
in
g
of
solid
to
be
charged
to
extractor.

W
f
=
Wet
weight
in
g
of
filtered
solids
and
filter
media.

W
t
=
Weight
in
g
of
tared
filters.

If
the
waste
does
not
contain
any
free
liquids,
100
g
of
the
material
will
be
subjected
to
the
extraction
procedure.

7.12
Place
the
appropriate
amount
of
material
(
refer
to
Step
7.11)
into
the
extractor
and
add
16
times
its
weight
with
water.

After
the
solid
material
and
water
are
placed
in
the
extractor,
the
operator
shall
begin
agitation
and
measure
the
pH
of
the
solution
in
the
extractor.
If
the
pH
is
>
5.0,
the
pH
of
the
solution
should
be
decreased
to
5.0
+
0.2
by
slowly
adding
0.5N
acetic
acid.
If
the
pH
is
<
5.0,
no
acetic
acid
should
be
added.
The
pH
of
the
solution
should
be
monitored,
as
described
below,
during
the
course
of
the
extraction,
and,
if
the
pH
rises
above
5.2,
0.5N
acetic
acid
should
be
added
to
bring
the
pH
down
to
5.0
+
0.2.
However,
in
no
event
shall
the
aggregate
amount
of
acid
added
to
the
solution
exceed
4
mL
of
acid
per
g
of
solid.
The
mixture
should
be
agitated
for
24
hours
and
maintained
at
20­
40
E
C
(
68­
104
E
F)
during
this
time.
It
is
recommended
that
the
operator
monitor
and
adjust
the
pH
during
the
course
of
the
extraction
with
a
device
such
as
the
Type
45­
A
pH
Controller,
manufactured
by
Chemtrix,
Inc.,
Hillsboro,
Oregon
97123,
or
its
equivalent,
in
conjunction
with
a
metering
pump
and
reservoir
of
0.5N
acetic
acid.
If
such
a
system
is
not
available,
the
following
manual
procedure
shall
be
employed.

NOTE:
Do
not
add
acetic
acid
too
quickly.
Lowering
the
pH
to
below
the
target
concentration
of
5.0
could
affect
the
metal
concentrations
in
the
leachate.

7.13.1
A
pH
meter
should
be
calibrated
in
accordance
with
the
manufacturer's
specifications.

7.13.2
The
pH
of
the
solution
should
be
checked,
and,
if
necessary,
0.5
N
acetic
acid
should
be
manually
added
to
the
extractor
until
the
pH
reaches
5.0
+
0.2.
The
pH
of
the
solution
should
be
adjusted
at
15­,
30­,
and
60­
minute
intervals,
moving
to
the
next
longer
interval
if
the
pH
does
not
have
to
be
adjusted
>
0.5
pH
units.

7.13.3
The
adjustment
procedure
should
be
continued
for
at
least
6
hours.

7.13.4
If,
at
the
end
of
the
24­
hour
extraction
period,
the
pH
of
the
solution
is
not
below
5.2
and
the
maximum
amount
of
acid
(
4
mL
per
g
of
solids)
has
not
been
added,
the
pH
should
be
adjusted
to
5.0
+
0.2
and
the
extraction
continued
for
an
additional
4
hours,
during
which
the
pH
should
be
adjusted
at
1­
hour
intervals.

7.14
At
the
end
of
the
extraction
period,
water
should
be
added
to
the
extractor
in
an
amount
determined
by
the
following
equation:

V
=
(
20)(
W)
­
16(

­
A
where:

V
=

extractor.

A
=
mL
of
0.5N
acetic
acid
added
during
extraction.

7.15
The
material
in
the
extractor
should
be
separated
into
its
component
liquid
and
solid
phases
in
the
following
manner:

7.15.1
Allow
slurries
to
stand
to
permit
the
solid
phase
to
settle
(
wastes
that
are
slow
to
settle
may
be
centrifuged
prior
to

combined.
This
combined
liquid
(
or
waste
itself,
if
it
has
<
0.5%
solids,
as
noted
in
Step
7.8)
is
the
extract.

7.17
The
extract
is
then
prepared
and
analyzed
using
the
appropriate
analytical
methods
described
in
Chapters
Three
and
Four
of
this
manual.

NOTE:
If
the
EP
extract
includes
two
phases,
concentration
of
contaminants
is
determined
by
using
a
simple
weighted
average.
For
example:
An
EP
extract
contains
50
mL
of
oil
and
1,000
mL
of
an
aqueous
phase.
Contaminant
concentrations
are
determined
for
each
phase.
The
final
contamination
concentration
is
taken
to
be:

NOTE:
In
cases
where
a
contaminant
was
not
detected,
use
the
MDL
in
the
calculation.
For
example,
if
the
MDL
in
the
oily
phase
is
100
mg/
L
and
1
mg/
L
in
the
aqueous
phase,
the
reporting
limit
would
be
6
mg/
L
(
rounded
to
the
nearest
mg).
If
the
regulatory
threshold
is
5
mg/
L,
the
waste
may
be
EP
toxic
and
results
of
the
analysis
are
inconclusive.

8.0
QUALITY
CONTROL
8.1
All
quality
control
data
should
be
maintained
and
available
for
easy
reference
or
inspection.

8.2
Employ
a
minimum
of
one
blank
per
sample
batch
to
determine
if
contamination
or
any
memory
effects
are
occurring.

8.3
All
quality
control
measures
described
in
Chapter
One
and
in
the
referenced
analytical
methods
should
be
followed.
