RE:
Comments

the
Use

Standards
Dear
Ms.
Wegman:

Thank
you
for
the
opportunity
to
review
the
above
referenced
draft
staff
work
paper
on
the
use
of
air
quality
data
related
to
exceptional
and
natural
events
for
particulate
matter.
The
State
of
Wyoming,
as
a
member
of
WESTAR,
has
been
working
for
more
than
a
year
to
provide
recommendations
on
how
the
Natural
Events
Policy
could
be
modified
to
function
better.
The
workgroup
recommendations
that
came
from
that
effort
are
to
be
considered
Wyoming's
recommendations
too.
While
certain
issues
contained
in
WESTAR's
recommendations
were
partially
covered,
I
would
like
to
see
an
effort
made
to
fully
address
all
of
them.

I
am
attaching
a
copy
of
our
specific
comments
of
the
draft
staff
work
paper
for
your
further
consideration.
We
are
available
to
discuss
any
questions
you
may
have
regarding
them.

Sincerely,

Dan
Olson,
Administrator
