Jenny­
changes
below..
Apologies
for
the
delay...

While
the
primary
environmental
impacts
of
the
HWC
MACT
replacement
standards
are
improvements
in
air
quality
associated
with
reduced
emissions
from
combustion
facilities,
other
non­
air
environmental
impacts
will
also
result
from
the
rule.
More
specifically,
use
of
air
pollution
control
devices
and
changes
in
hazardous
waste
burning
practices
will
result
in
water
and
solid
waste
impacts.
Systems
that
use
wet
scrubbers
to
control
chlorine
emissions
will
generate
an
additional
775**
1275**
million
gallons
of
wastewater
per
year.
In
addition,
systems
that
install
dry
scrubbers
to
control
chlorine
emissions
will
generate
more
than
3,500
tons
of
spent
sorbent
per
year.
Facilities
using
activated
carbon
to
control
emissions
of
dioxins/
furans
and
mercury
will
generate
nearly
3900
tons
of
carbon
on
an
annual
basis.
Controls
for
other
pollutants
will
increase
annual
water
consumption
by
approximately
400
million
gallons
and
generate
an
additional
*
7500
to
8500**
tons
of
solid
waste
per
year.
The
cost
estimates
presented
in
Chapter
4
and
Chapter
5
account
for
the
treatment
and
disposal
of
all
wastewater
and
solid
waste
generated
as
a
result
of
the
standards.

Impacts
of
Standards
Dear
Lucky,
I
hope
you
enjoyed
4th
of
July
festivities.
I
sent
you
a
paragraph
with
some
numbers
quantifying
impacts
of
the
final
standards
(
see
below)
back
in
May.
Have
these
figures
changed
since
then?
Lyn
seems
to
think
they
have.
It's
unclear
whether
he
has
an
old
version
of
the
numbers
or
if
they've
been
updated
since
you
last
sent
them
to
me.
Could
you
please
look
over
the
numbers
I
have
posted
in
this
email
and
let
me
know
if
they
are
the
most
recent
ones?
Thank
you
very
much,
Jenny
L.
Benedict
