Dear
Ms
Bartram:

This
date
per
your
request
I
spoke
with
Mr.
Paul
Chu
and
Ms.
Naomi
Goodman
of
The
Electric
Power
Research
Institute
(
EPRI)
on
the
issues
of
sodium
nitrite
use
at
power
plants
and
the
presence
of
polycyclic
aromatic
compounds(
PACs)
in
coal.

Mr.
Chu
indicated
that
he
has
seen
references
that
some
power
plants
use
sodium
nitrite
as
a
corrosion
inhibitor
in
boilers,
but
has
no
definitive
information
on
numbers.

Ms.
Goodman
indicated
that
there
is
limited
data
showing
the
existence
of
PACs
in
coal.
The
data
are
old
(
from
the
1970'
s)
some
are
questionable
due
to
analytical
interference
and
detection
limit
issues.
At
some
point
in
the
past
EPRI
distributed
a
listing
of
Pacs
in
Coal
to
The
Edison
Electric
Institute,
who
in
turn
distributed
it
to
its
member
utilities
for
use
in
reporting
to
EPA.
The
data
summary
is
also
posted
on
an
EPRI
web
site
available
to
EPRI
member
utilities.

Ms.
Goodman
indicated
that
they
have
confidence
that
four
of
the
19
PACs
are
likely
to
be
present
in
coal:
namely:

6.

8.

Ms.
Goodman
stressed
that
any
PACs
present
in
the
coal
would
be
destroyed
during
combustion.
There
are
limited
data
on
PACs
in
coal
pile
runoff
from
various
DOE
air
toxic
studies
from
the
1990'
s.

Additionally,
Ms
Goodman
indicated
that
EPA
provides
guidance
on
PACs
in
oil.
She
also
indicated
that
the
American
Petroleum
Institute
and
The
Total
Petroleum
Hydrocarbons
Working
Group
each
have
summarized
PAC
data
in
oil
and
that
their
total
PAC
numbers
agree
within
a
factor
of
about
two.

Should
you
require
additional
information,
feel
free
to
contact
me.

Sincerely,
