Subject:
"
PCBs,
Mining,
and
Water
Pollution"

Carey:

I
am
attaching
two
similar
peer
reviewed
papers
entitled
 
£
PCBs,
Mining,
and
Water
Pollution.
 
¥
The
paper
presented
at
the
Polson
Conference
is
for
the
persons
not
very
familiar
with
mines.
It
has
a
map
of
the
Idarado
mine
near
Telluride,
CO
to
demonstrate
how
big
mines
can
be
and,
by
implication,
how
much
their
power
needs
in
the
form
of
transformers
and
capacitors
can
be.

The
paper
published
in
July
2003
issue
of
Mining
Environmental
Management
London,
UK
is
tailored
for
the
mining
industry
which
already
knows
how
big
mines
are.
Both
papers
have
the
important
information
on
PCBs.
I
use
this
one
most
of
the
time
because
of
the
imprimatur
of
having
been
published
in
an
international
mining
journal
that
has
readers
in
68
countries.
A
Reprint
is
in
the
mail.
More
are
available.

The
above
papers
are
on
the
EPA
Regions
8,
10,
and
the
Utah
Department
of
Environmental
Quality
websites.

I
suggest
anyone
who
works
with
mines
either
surface
or
underground
(
including
large
gravel
pits
and
quarries)
should
be
familiar
with
this
potential
problem.
The
paper
has
so
far
been
distributed
to
the
national
mining
team
and
OSWER
OEPPR
REMOVAL
MANAGERS,
