NPRM
I
wasn't
sure
which
of
you
are
in
the
office
today,
so
I'm
copying
everyone
to
cover
the
bases.
So
don't
worry,
I
haven't
forgotten
about
you.
I
did
some
leisurely
weekend
reading
and
I
just
have
a
few
minor
points
on
the
NPRM.

1.
On
pages
100
and
149
there
seems
to
be
an
inconsistency
on
whether
the
temperature
bins
are
10
or
25
degrees.

The
difference
in
temperature
precision
is
deliberate.
There
are
two
different
cycles
which
are
being
measured
and
the
accuracy
of
the
data
collection
should
reflect
that.
On
page
100
we
are
measuring
the
temperature
of
the
catalyst
during
driving
on
the
road
cycle
­­
the
temperature
measured
will
be
between
20
C
(
or
whatever
the
ambient
temperature
is)
up
to
about
900­
950
C.
Because
of
the
wide
range
of
temperatures
a
25
C
bin
is
appropriate.
On
the
other
hand,
the
temperatures
measured
in
the
discussion
on
page
149
is
the
catalyst
temperature
during
the
bench
cycle.
The
bench
cycle
will
vary
only
90
C
(
800
to
890
at
standard
conditions),
the
precise
measurement
of
this
temperature
is
critical,
a
25
C
bin
is
too
wide
for
this
purpose,
consequently
we
are
proposing
the
10
C
bin
discussed
in
that
section.

2.
We
will
fix
the
following:

page
93,
"
though"
should
be
"
through"
page
106,
"
forth"
should
be
"
fourth"
page
130,
need
a
close
quote
on
"
significant
regulatory
action"
page
133,
section
D
should
start
a
new
paragraph
3.
On
page
118,
the
title
for
section
IV
does
not
reflect
the
content
that
follows
We
will
also
fix
the
headings
as
follows:
Page
118
"
IV.
What
are
the
economic
and
environmental
impacts?"
Page
121
"
V.
What
are
the
opportunities
for
public
participation?"

4.
There
is
some
odd
formatting
in
the
appendices­­
for
example,
the
text
on
page
188
above
the
SRC
graph,
and
several
places
with
partially
or
completely
blank
pages
The
formatting
of
the
tables
and
the
graphs
change
with
each
printer­
driver
that
is
used.
In
the
final
version,
we
will
assure
that
the
graphs
appear
in
the
correct
spot.

I
am
working
toward
concluding
review
today
or
tomorrow.

me

any
