Dear
Mr.
Prager:

Thank
you
for
your
petition
of
July
8,2002,
to
Christine
Todd
Whitman,
Administrator
of
the
U.
S.
Environmental
Protection
Agency,
in
which
you
requested
an
additional
carbon
monoxide
(
CO)
emission
limit
be
added
to
the
Clean
Air
Act
Section
129
maximum
achievable
control
technology
(
MACT)
standards
for
large
municipal
waste
combustion
(
MWC)
units
(
Subpart
Cb).
We
appreciate
your
concern
with
ths
issue.

As
you
note,
the
MACT
standards
adopted
in
2000
for
small
MWC
units
(
Subpart
BBBB)
do
contain
a
unique
CO
emission
limit
for
this
type
of
fluidized
bed
MWC.
We
understand
that
you
are
simply
requesting
that
the
CO
limit
in
the
small
MWC
standards
be
limits
in
the
large
MWC
standards.
After
careful
consideration
and
review,
I
add
your
request
to
the
issues
to
be
addressed
in
the
5­
year
review
of
the
MACT
e
MWC
units.
That
review
will
be
initiated
next
month
(
September
2002).
As
you
are
aware,
any
changes
made
to
the
MACT
standards
will
go
through
proposal
and
public
comment
prior
to
adoption.
Changes
made
to
the
MACT
standards
would­
then
be
incorporated
into
the
Federal
plan
(
Subpart
FFF)
for
laxge
MWC
units.
.

Again,
thank
you
for
your
petition.
I
appreciate
the
opportunity
to
be
of
service
and
trust
the
information
provided
is
helpful.
If
you
have
further
questions,
please

Wayland
