AMENDMENTS
The
revisions
to
Regulation
No.
11
reduce
the
maximum
number
of
vehicles
that
may
be
exempted
from
conventional
emissions
testing
at
an
inspection
station
through
the
use
of
the
clean
screen
program.
Regulation
No.
11
previously
provided
that
up
to
80%
of
the
fleet
may
be
evaluated
by
the
clean
screen
program,
beginning
February
28,
2005.
However,
it
appeared
at
the
hearing
that
the
goal
of
screening
80%
of
the
vehicle
fleet
with
the
clean
screen
program
was
unrealistic;
a
more
realistic
goal
would
be
to
screen
50%
of
the
vehicle
fleet.
Revising
the
regulation
and
the
SIP
to
reflect
this
reality
will
result
in
an
emission
reduction
benefit
for
purposes
of
the
attainment
demonstration.

The
Commission
also
repealed
provisions
stating
that
the
NOx
standards
and
gas
cap
test
requirements
were
not
to
be
included
in
the
State
Imlementation
Plan.
Previously,
such
requirements
were
not
necessary
to
the
SIP
because
the
State
took
no
credit
for
the
measures
for
SIP
modeling
purposes.
The
requirements
are,
however,
necessary
for
the
attainment
demonstration
set
out
in
the
Early
Action
Compact
Ozone
Action
Plan
for
the
8­
hour
Ozone
Control
Area.
Therefore,
these
requirements
must
now
be
incorporated
into
the
SIP.

The
statutory
authority
for
the
rule
change
is
set
out
at
section
42­
4­
306(
23)(
a),
C.
R.
S.

This
rule
revision
is
based
on
the
recognition
that
practical
and
technical
hurdles
make
it
unlikely
that
the
clean
screen
program
will
achieve
the
80%
level
previously
authorized
by
the
regulation.
The
amendment
is
not
intended
to
reduce
pollution,
rather
the
change
is
necessary
so
that
the
SIP
will
reflect
the
true
nature
of
the
clean
screen
program.
Since
this
change
is
not
intended
to
reduce
air
pollution,
the
requirements
of
25­
7­
110.8
do
not
apply.
