If
you
documented
in
your
notification
of
compliance
status
report
that
an
MCPU
has
Group
2
batch
36
process
vents
because
the
non­

organic
HAP
usage
is
less
than
10,000
lb/
yr,
as
specified
in
§
63.2460(

of
the
amount
of
HAP
material
used,
and
calculate
the
daily
rolling
annual
sum
of
the
amount
used
no
less
frequently
than
monthly.
If
a
record
indicates
usage
exceeds
10,000
lb/
yr,
you
must
estimate
emissions
for
the
preceding
12
months
based
on
the
number
of
batches
operated
and
the
estimated
emissions
for
a
standard
batch,

and
you
must
begin
recordkeeping
as
specified
in
paragraph
(
e)(

of
this
section.
After
1
year,
you
may
revert
to
recording
only
usage
if
the
usage
during
the
year
is
less
than
10,000
lb.

vents
in
an
MCPU
will
be
less
than
1,000
lb/

for
the
anticipated
number
of
standard
batches,
then
you
must
keep
records
of
the
number
of

device.

Note
to
definition
for
point
of
determination:
The
regulation
allows
determination
of
the
characteristics
of
a
wastewater
stream
(
1)
at
the
point
of

This
definition
does
not
apply
to
a
condenser
that
is
used
to
remove
materials
that
would
hinder
performance
of
a
downstream
recovery
device
as
follows:

(
1)
To
remove
water
vapor
that
would
cause
icing
in
a
downstream
condenser,
or
(
2)
To
remove
