Art
and
Amy,

I'm
sending
this
note
on
behalf
of
Lydia
Wegman,
John
Silvasi,
and
Allen
Basala.
Two
important
things:

We
want
to
be
sure
you
have
an
accurate
answer
to
your
question
Friday
about
our
interpretation
of
Clean
Air
Act
RACT
requirements
in
8­
hour
nonattainment
areas
in
the
case
of
sources
that
previously
met
RACT
for
the
1­
hour
standard.
We
think
that
the
meeting
Friday
may
have
left
misimpressions.
Attached
is
a
short
piece
that
OAQPS
put
together
that
summarizes
key
preamble
statements
on
this
topic
and
points
you
to
the
appropriate
pages.

Second,
we
expect
to
be
ready
by
Wednesday
to
give
you
a
detailed
briefing
on
results
of
an
analysis
of
emission
reduction
targets
for
8­
hour
ozone
attainment,
potential
local
controls,
and
costs.
As
I
think
you
know,
the
scope
of
this
analysis
is
all
of
the
16
8­
hour
nonattainment
areas
in
the
eastern
half
of
the
country
that
are
projected
in
nonattainment
in
2010
in
the
CAIR
base
case.
Allen
has
called
Amy
about
setting
a
meeting
time.
