Background
°
Costs
associated
with
the
ambient
standard
were
assessed
in
1997
when
the
8­
hr
O3
NAAQS
was
promulgated.

°
The
implementation
rule
examines
differences
in
alternative
implementation
frameworks
°
The
most
flexible
and
legally
defensible
framework
is
the
regulatory
baseline
°
The
base
case
for
air
quality
modeling
is
what
would
happen
in
the
absence
of
8­
hr
O3
SIPs
and
additional
federal
rules
(
