Summary
of
Management
Data
Finally,
if
it
is
economically
feasible
to
construct
on­
site
recovery
facilities,
part
of
a
population
of
1,758
plants
(
1,585
unique
plants)
disposing
approximately
696,000
tons
off
site
may
receive
benefits
from
the
proposed
rule.
A
break­
even
cost
analysis
was
conducted
on
the
eight
waste
types
from
selected
SIC
codes
included
in
the
analysis
(
results
presented
in
Table
5­
21).
Based
on
the
break­
even
cost
analysis,
681
of
the
1,758
plants
(
some
plants
are
double­
counted
because
they
disposed
more
than
one
of
the
eight
waste
types)
representing
415,000
of
the
696,000
tons
may
construct
on­
site
recovery
facilities.
Incineration,
energy
recovery
and
fuel
blending,
aqueous
inorganic
treatment,
aqueous
organic
and
inorganicHowever,
a
significant
limitation
is
that
it
is
unknown
if
all
eight
of
these
wastes
are
of
sufficient
quality
for
recovery.
Five
of
the
eight
wastes
types
have
been
identified
as
likely
having
sufficient
constituent
mix/
concentration
quality
for
recovery.
Emission
control
dust
(
K061)
from
the
steel
works
industry
has
a
past
history
of
being
recovered
for
zinc
values
prior
to
the
delisting
of
the
significantly
cheaper
Envirosource
stabilization
technology.
Most
of
the
metal­
containing
liquids
from
the
printed
circuit
board
industry
were
reported
being
disposed
either
on­
site
or
off­
site
by
chemical
precipitation
and
included
in
this
group
of
waste.
Upon
further
inspection
of
the
Biennial
Report
data,
the
copper­
containing
sludge
precipitated
from
this
treatment
process
often
goes
on
to
metals
recovery.
This
waste
is
of
sufficient
quality
for
recovery.
Spent
aluminum
potliner
(
K088)
from
the
aluminum
industry
has
a
proven
technology
for
recovering
fluoride
values.
The
Vortec
technology
has
been
implemented
at
least
at
two
sites
and
licensing
agreements
can
be
arranged
for
construction
at
other
sites.
The
Vortec
technology
meets
universal
treatment
standards
for
potliner
waste.
Spent
catalyst
(
K171/
K172)
from
the
petroleum
refining
industry
is
believed
to
be
recoverable
based
on
communications
with
reclaimers.
Spent
pickle
liquor
(
K062)
from
the
steel
works
industry
also
is
believed
to
have
sufficient
quality
for
recovery
of
acid
values.
The
remaining
three
wastes
are
not
assumed
to
be
of
sufficient
quality
for
recovery
in
this
analysis.
Based
on
the
break­
even
analysis
for
the
five
waste
types
of
sufficient
quality
for
recovery,
183
out
of
331
plants
representing
222,000
of
the
467,000
tons
may
construct
on­
site
recovery
facilities.
Incineration,
aqueous
treatment,
stabilization,
and
disposal
account
for
8121,000
tons,
305156,000
tons,
171,000
tons,
67,000
tons,
16150,000
tons,
and
10797,000
tons,
respectively.
In
addition,
part
of
a
population
of
86
plants
disposing
approximately
315,000
tons
on
site
may
receive
benefits
from
the
proposed
rule.
A
break­
even
cost
analysis
was
conducted
on
the
two
waste
types
from
selected
SIC
codes
included
in
the
analysis
(
results
presented
in
Table
5­
22).
Based
on
the
break­
even
cost
analysis,
27
of
the
86
plants
representing
181,000
of
the
315,000
tons
may
construct
on­
site
recovery
facilities.
Aqueous
inorganic
treatment,
other
treatment,
and
disposal
account
for
35,000
tons,
88,000
tons,
and
191,000
tons,
respectively.

For
the
wastes
that
already
are
being
recovered
or
were
being
recovered
in
1997
and
five
waste
types
being
disposed
with
high
recovery
potential
(
discussed
in
Section
5),
the
total
number
of
plants
affected
is
estimated
to
be
1,749.
These
plants
recover
approximately
1,408570,000
tons
either
on
site
or
within
the
same
industry
group
and
may
benefit
from
the
exclusion
from
RCRA
jurisdiction.
