Re:

Facilities
Date:
October
22,
2004
From:
Paul
Shriner
This
memo
clarifies
whether
co­
located
facilities
are
subject
to
phase
II,
Phase
III,
or
case­
by­
case
best
professional
judgement
(
BPJ).

Background
The
Final
Phase
II
Preamble
states
"
Section
II
[
Scope]
also
makes
clear
that
a
manufacturing
facility
is
not
covered
by
this
final
rule
just
because
it
is
co­
located
with
another
Phase
II
facility."
(

FR
41610).
40
CFR
125.90(
b)
provides
that
"[
e]
xisting
facilities
that
are
not
subject
to
requirements
under
this
or
another
subpart
of
this
part
must
meet
requirements
under
section
316(
b)
of
the
CWA
determined
by
the
Director
on
a
case­
by­
case,
best
professional
judgment
(
BPJ)
basis."

Applicability
of

316(
b)
requirements
to
co­
located
electric
generators
and
manufacturers
For
Phase
III,
under
the
50
MGD
option,
EPA
proposed
any
co­
located
facilities
with
a
combined
flow
exceeding
50
MGD
would
be
subject
to
the
uniform
national
requirements.
The
following
table
combines
the
applicability
of
the
final
Phase
II
rule
and
scope
of
the
proposed
Phase

Exhibit

provides
details
on

facilities
where
the
SIC
code
suggests
manufacturing
is
the
primary
activity.
EPA
did
not
find
any
manufacturing
facility
less
than
50
MGD
where,
combined
with
any
electric
generating
activities,
the
total
combined
flow
was
more
than
50
MGD.
All
manufacturing
facilities
greater
than
50
MGD
were
already
costed
for
performance
standards
for
their
total
reported
intake
flows.
