Response
to
your
query
about
scientific
case
for
lowering
annual
PM
standard
Dear
Dr.
Graham:

Thank
you
again
for
taking
the
time
to
meet
with
us
on
November
18th
to
discuss
the
EPA's
impending
decision
on
new
Particulate
Matter
standards.

At
that
meeting,
I
promised
to
get
back
to
you
with
a
summary
of
the
scientific
literature
supporting
our
point
that
the
annual
PM2.5
standard
should
be
lowered
to
12
mcg/
m3.
Please
find
attached
a
letter
that
provides
this
summary.
I
have
included
in
this
letter
details
from
two
new
analyses
that
have
not
yet
been
published,
but
provide
the
specific
evidence
that
you
mentioned
you
were
seeking.
I
hope
you
will
agree
that
the
scientific
evidence
is
robust
and
makes
clear
that
reducing
PM2.5
exposures
below
the
current
annual
standard
of
15
mcg/
m3
to
12
mcg/
m3
will
save
lives
and
improve
public
health.

We
will
share
a
copy
of
this
letter
with
EPA
Administrator
Johnson
and
his
staff
as
well.

you
have
any
questions
about
what
I've
