For
some
sites,
ARB
staff
were
able
to
apply
U.
S.
EPA's
data
substitution
policy
to
demonstrate
that
the
area
attains
the
standards
even
though
the
data
were
not
complete.
Yearly
data
is
deemed
complete
when
at
least
75
percent
of
the
scheduled
samples
are
available
for
each
quarter
for
all
three
years.
For
monitors
not
deemed
complete,
data
substitution
is
allowed
if
at
least
50
percent
of
the
scheduled
samples
are
available.
For
each
monitor
eligible
for
data
substitution,
ARB
staff
selected
the
maximum
data
value
across
all
three
years
for
the
quarter
and
substituted
this
value
for
all
missing
data
in
that
quarter.

Using
the
substituted
data,
ARB
staff
then
recalculated
the
quarterly
average,
annual
average,
three­
year
annual
average,
24­
hour
98th
percentile,
and
3­
year
average
24­

98th
percentile.
