This
memorandum
describes
the
changes
to
and
the
revised
results
of
the
impacts
analysis
for
vertical
storage
tanks
associated
with
continuous
processes.
No
changes
have
been
made
to
the
MACT
floor,
but
three
changes
have
been
made
in
the
impacts
analysis.
First,
the
HAP
partial
pressures
for
tanks
that
store
multiple
HAP
originally
were
determined
by
summing
the
vapor
pressure
values
for
each
HAP
in
the
tank.
1
We
could
not
determine
the
HAP
partial
pressures
using
Raoult's
Law
because
we
do
not
have
the
liquid
composition
for
the
tanks.
However,
the
original
approach
clearly
overestimated
the
HAP
partial
pressures
for
the
tanks.
To
better
approximate
the
total
HAP
partial
pressures,
this
revised
analysis
estimates
individual
HAP
partial
pressures
using
weighted
average
vapor
pressures
based
on
the
ratio
of
the
individual
HAP
emissions
to
the
total
HAP
emissions.
This
change
reduced
the
HAP
partial
pressures
for
numerous
tanks,
including
three
tanks
for
which
the
partial
pressure
fell
below
the
MACT
floor
cut
off
of
1.0
psia.

A
second
change
concerned
the
HAP
reductions
for
tanks
that
already
have
an
add­
on
control
device
that
reduces
emissions
by
less
than
95
percent.
The
original
analysis
contained
an
error
in
the
calculation
that
resulted
in
underestimation
of
the
emission
reduction
that
would
be
achieved
by
meeting
the
MACT
floor
requirement
of
95
percent
control.
A
third
change
involves
a
storage
tank
that
is
currently
controlled
with
a
scrubber.
The
original
analysis
assumed
the
scrubber
achieves
no
control
for
all
for
one
of
the
scrubbers.
This
analysis
applies
the
assumption
consistently
for
all
of
the
scrubbers.

The
lowering
of
estimated
emission
reductions
and
costs
due
to
the
first
change
are
partially
offset
by
the
increases
associated
with
the
second
and
third
changes.
Collectively,
for
the
storage
tanks
in
the
database,
these
changes
lower
the
emission
reduction
by
less
than
1
ton
per
year,
capital
costs
are
reduced
by
about
$
35,000,
and
annual
costs
are
reduced
by
about
$
6,000
per
year.
The
database
is
assumed
to
represent
half
of
the
storage
tanks
associated
with
continuous
processes.
1
Therefore,
the
nationwide
emission
reductions
are
about
1
tpy
lower
than
in
the
original
analysis,
the
capital
costs
are
about
$
70,000
lower,
and
the
annual
costs
are
about
$
12,000
per
year
lower.
As
a
result
of
these
changes,
the
cost
effectiveness
has
also
changed
from
$
4,800
per
ton
to
$
4,700
per
ton.
