USING
UPDATED
NAICS
CODE
BASED
SIZED
STANDARDS
FOR
SMALL
BUSINESS
DETERMINATIONS
FOR
THE
FINAL
316(
B)
PHASE
III
RULE
As
described
in
Chapter
D1
of
the
Economic
and
Benefits
Analysis
for
the
Final
Section
316(
b)
Phase
III
Existing
Facilities
Rule
(
EPA­
821­
R­
06­
001),
the
SBA
small
business
size
standards
changed
from
a
SIC
code­
based
system
to
a
NAICS
code­
based
system
on
October
1,
2000.
The
NAICS
code
system
was
further
updated
effective
January
5,
2006.
Because
EPA
structured
its
data
collection
effort
for
existing
facilities
before
these
changes
and
based
on
the
SIC
code
framework,
EPA
performed
the
small
entity
analysis
for
existing
facilities
based
on
SIC
codes.
This
memorandum
presents
the
methodology
for
using
the
updated
NAICS­
based
size
standards,
effective
January
5,
2006,
for
use
in
the
small
entity
analysis.

Identifying
NAICS
Codes
and
Thresholds
EPA
started
with
the
unique
firm­
level,
4­
digit
SIC
codes
for
firms
that
own
existing
facilities
potentially
subject
to
Phase
III
regulation.
EPA
used
information
from
the
Economic
Census,
1997
Economic
Census:
Bridge
Between
NAICS
and
SIC,
to
determine
1997
NAICS
Codes
classifications
for
these
firms.
1
EPA
also
used
an
additional
Economic
Census
publication
and
dataset,
1997
NAICS
Matched
to
2002
NAICS,
to
bring
all
associated
NAICS
codes
forward
to
NAICS
2002
so
that
the
most
current
small
business
thresholds
could
be
used
(
Census,
2003).
EPA
then
matched
size
standards
from
the
updated
size
standards
effective
January
2006
to
the
NAICS
codes
associated
with
each
firm's
SIC
code.
Table
1
presents
firm­
level
SIC
codes
and
sector
descriptions,
and
the
corresponding
NAICS­
based
codes,
sector
descriptions,
and
small
business
thresholds,
of
firms
owning
any
Manufacturers
survey
facilities
(
i.
e.,
regardless
of
intake
size)
determined
to
be
potentially
subject
to
the
Phase
III
regulation.
For
ease
of
reference,
gray
shading
is
used
to
highlight
SIC
codes
with
corresponding
NAICS
code
that
have
a
different
size
standard
from
the
SIC
standard.

Determination
of
NAICS
Based
Size
Thresholds
In
instances
in
which
a
single
SIC
code
maps
to
more
than
one
NAICS
code
and
the
size
thresholds
for
the
NAICS
codes
vary,
EPA
used
the
higher/
highest
of
the
NAICS­
based
size
thresholds
for
the
small
entity
determination.
Using
the
higher/
highest
of
the
NAICS­
based
size
thresholds
for
the
determination
provides
a
more
conservative
test
of
the
chance
that
a
firm
would
have
been
classified
as
small
if
the
NAICS­
based
size
thresholds
had
been
used
in
the
small
entity
analysis
instead
of
the
SIC­
based
size
thresholds.
