RE:
Moisture
Content
Equation
Mary
Tom,

Thanks
for
the
feedback.
I
was
looking
at
this
as
a
technical
information/
definitional
need
and
I
guess
EPA
was
looking
at
it
from
more
of
a
process
standpoint.
There
is
no
technical
issue
in
the
wood
products
field
about
the
dry
basis
moisture
content
definition,
of
course,
which
is
in
the
USDA
Wood
Handbook.
Since
its
not
in
the
rule,
this
sounds
like
something
that
needs
to
be
referenced
in
one
of
the
implementation
documents
being
developed.

Have
a
wonderful
trip
to
Russia.
I
hope
you
get
a
girl.

Re:
Moisture
Content
Equation
Dear
John,

The
moisture
content
equations
in
the
proposed
and
final
rules
have
a
different
purpose.
The
equation
in
the
proposed
rule
was
to
be
used
to
calculate
moisture
content
of
grab
samples
(
weight
percent
on
a
dry
basis).
Based
on
comments
from
industry,
we
eliminated
the
grab
sampling
requirements
and
the
associated
equation
(
FR
page
1317)
from
the
proposed
rule.
The
equation
we
included
in
the
final
rule
(
page
402)
is
used
to
convert
wet
basis
moisture
measurements
made
by
a
continuous
moisture
monitor
to
a
dry
basis.

Regards,
Mary

Moisture
Content
Equation
Mary
Tom,

Yesterday
I
noted
the
apparent
absence
of
a
dry
basis
moisture
content
equation
in
the
final
rule.
Did
I
miss
it
somewhere?
All
I
could
find
was
a
conversion
equation
for
turning
a
wet
basis
moisture
content
to
a
dry
basis
moisture
content
(
page
402).
The
equation
is
in
the
proposed
rule
(
FR
page
1317)
and
we
found
it
quite
helpful.
It
would
seem
to
be
a
necessary
item
for
the
rule
to
define
since
there
are
important
regulatory
parameters
that
are
defined
by
dry
basis
moisture
content.

Please
let
me
know
if
I
just
managed
to
overlook
the
equation's
presence
in
some
other
form.
I
was
preparing
a
presentation
for
the
AF&
PA
workshop
and
couldn't
track
it
down
for
reference.

Best
of
luck
on
your
next
trip
east
to
adopt
another
child.
Will
it
be
a
girl
this
time?
When
do
you
leave?
