Opt­

New

at
the
end
of
Chapter
II.

C.
Budgets
for
"
opt­
in"
sources.

Elsewhere
in
this
proposed
rule,
EPA
has
proposed
to
preclude
expansion
of
the
affected
sources
to
categories
of
sources
which
do
not
conform
to
EPA's
criteria
for
inclusion.
However,
this
general
exclusion
is
not
intended
to
exclude
specific
source
that
elect
to
be
covered
by
the
rule.
To
the
extent
that
one
or
more
sources
elect
to
be
covered
by
the
rule,
the
state
may
include
those
sources
in
its
IAQR
SIP.
Baseline
emissions
for
those
sources
must
reflect
the
annual
emissions
that
would
occur
in
the
absence
of
participation
in
the
IAQR
SIP,
and
would
be
diminished
in
the
future
if
that
source
category
were
further
controlled
for
SO2
or
NOx.
The
state's
budget
would
be
augmented
by
the
amount
of
these
baseline
emissions.

Early
reduction
credits
for
NOx:
New
section
"
D."
at
the
end
of
Chapter
II.

D.
Early
reduction
credits
for
NOx
emissions.

The
proposed
rule
does
not
provide
credits
for
reduction
of
NOx
emissions
from
EGU's
prior
to
the
first
compliance
period
(
2010).
However,
EPA
seek
comment
on
the
merits
and
problems
associated
with
such
an
early
reduction
credit
program,
as
well
as
ideas
on
how
such
a
program
could
be
structured.
