Industry
Information
Collection

UWAG
informed
EPA
that
they
are
collecting
information
from
their
members
to
aid
in
EPA's
steam
electric
detailed
study,
and
will
provide
aggregated
data
to
EPA.
They
noted
that
they
do
not
expect
to
have
100
percent
participation
from
their
members.
EPA
stated
that
they
have
not
yet
decided
if
they
will
pursue

specific
data
from
nine
or
less
facilities.

UWAG
will
provide
a
qualitative
discussion
to
EPA
on
several
of
the
topics
discussed
during
the
February
22,
2005
meeting
including:

Technologies
or
process
changes
that
can
be
more
readily
adopted
by
new
facilities
than
existing
facilities;

The
effects
of
the
316(
b)
rule
and
other
regulations
on
wastewater
discharges;
and

Similarities
and
differences
between
combined
cycle
plants
and
traditional
steam
electric
facilities.

2002
PCS
and
TRI
Data
°
EPA
provided
a
copy
of
the
2002
PCS
and
TRI
data
for
the
steam
electric
industry
to
UWAG
on
April
8.
UWAG
is
reviewing
the
data
and
will
provide
any
comments
to
EPA.

°
UWAG
is
investigating
the
possible
sources
of
the
boron
discharges
and
will
provide
information
to
EPA.

°
UWAG
believes
that
the
chlorine
releases
reported
to
TRI
are
incorrect.
Chlorine
as
Cl
2
should
not
exist
at
the
pH
of
the
discharge
streams.
The
facilities
reporting
chlorine
plan
to
submit
revisions
to
TRI.

Biofouling
°
EPA
asked
UWAG
about
chlorine
use
and
heat
treatment
to
prevent
biofouling.
Mike
Winkler
stated
that
facilities
using
closed­
loop
systems
will
not
discharge
until
the
chlorine
has
dissipated.
Once­
through
systems
will
adhere
to
their
two­
hour
limit.
If
facilities
can
not
meet
the
chlorine
limit,
they
will
either
modify
their
chemical
use
or
dechlorinate
before
discharge.
Heat
treatment
is
only
used
to
control
zebra
mussels.
Facilities
do
not
use
heat
treatment
to
prevent
biofouling.

Site
Visits
°
UWAG
asked
about
the
possibility
of
EPA
conducting
site
visits.
They
mentioned
that
sites
would
be
willing
to
participate
if
EPA
did
not
plan
to
collect
wastewater
samples
during
the
visit.
EPA
will
evaluate
their
needs
and
determine
the
objectives
for
any
potential
site
visits.
