E.
Regulatory
Flexibility
Act
The
Regulatory
Flexibility
Act
(
RFA)
generally
requires
an
agency
to
conduct
a
regulatory
flexibility
analysis
of
any
rule
subject
to
notice
and
comment
rulemaking
requirements
unless
the
agency
certifies
that
the
rule
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.
Small
entities
include
small
businesses,
small
not­
for­
profit
enterprises,
and
small
governmental
jurisdictions.
This
final
rule
will
not
have
a
significant
impact
on
a
substantial
number
of
small
entities
because
SIP
approvals
under
section
110
and
subchapter
I,
part
D
of
the
Clean
Air
Act
do
not
create
any
new
requirements
but
simply
approve
requirements
that
the
State
is
already
imposing.
Therefore,
because
the
Federal
SIP
approval
does
not
create
any
new
requirements,
I
certify
that
this
action
will
not
have
a
significant
economic
impact
on
a
substantial
number
of
small
entities.
Moreover,
due
to
the
nature
of
the
federal­
state
relationship
under
the
Clean
Air
Act,
preparation
of
flexibility
analysis
would
constitute
federal
inquiry
into
the
economic
reasonableness
of
state
action.
The
Clean
Air
Act
forbids
EPA
to
base
its
actions
concerning
SIPs
on
such
grounds.

F.
Unfunded
Mandates
Under
section
202
of
the
Unfunded
Mandates
Reform
Act
of
1995
(``
Unfunded
Mandates
Act''),
signed
into
law
on
March
22,
1995,
EPA
must
prepare
a
budgetary
impact
statement
to
accompany
any
proposed
or
final
rule
that
includes
a
federal
mandate
that
may
result
in
estimated
annual
costs
to
state,
local,
or
tribal
governments
in
the
aggregate,
or
to
the
private
sector,
of
$
100
million
or
more.
Under
section
205,
EPA
must
select
the
most
costeffective
and
least
burdensome
alternative
that
achieves
the
objectives
of
the
rule
and
is
consistent
with
statutory
requirements.
Section
203
requires
EPA
to
establish
a
plan
for
informing
and
advising
any
small
governments
that
may
be
significantly
or
uniquely
impacted
by
the
rule.
EPA
has
determined
that
this
approval
action
does
not
include
a
federal
mandate
that
may
result
in
estimated
annual
costs
of
$
100
million
or
more
to
either
state,
local,
or
tribal
governments
in
the
aggregate,
or
to
the
private
sector.
This
federal
action
approves
preexisting
requirements
under
state
or
local
law,
and
imposes
no
new
requirements.
Accordingly,
no
additional
costs
to
state,
local,
or
tribal
governments,
or
to
the
private
sector
result
from
this
action.

G.
Submission
to
Congress
and
the
Comptroller
General
The
Congressional
Review
Act,
5
U.
S.
C.
801
et
seq.,
as
added
by
the
Small
Business
Regulatory
Enforcement
Fairness
Act
of
1996,
generally
provides
that
before
a
rule
may
take
effect,
the
agency
promulgating
the
rule
must
submit
a
rule
report,
which
includes
a
copy
of
the
rule,
to
each
House
of
the
Congress
and
to
the
Comptroller
General
of
the
United
States.
EPA
will
submit
a
report
containing
this
rule
and
other
required
information
to
the
U.
S.
Senate,
the
U.
S.
House
of
Representatives,
and
the
Comptroller
General
of
the
United
States
prior
to
publication
of
the
rule
in
the
Federal
Register.
This
rule
is
not
a
``
major''
rule
as
defined
by
5
U.
S.
C.
804(

H.
Petitions
for
Judicial
Review
Under
section
307(
b)(
1)
of
the
Clean
Air
Act,
petitions
for
judicial
review
of
this
action
must
be
filed
in
the
United
States
Court
of
Appeals
for
the
appropriate
circuit
by
May
3,
1999.
Filing
a
petition
for
reconsideration
by
the
Administrator
of
this
final
rule
does
not
affect
the
finality
of
this
rule
for
the
purposes
of
judicial
review
nor
does
it
extend
the
time
within
which
a
petition
for
judicial
review
may
be
filed,
and
shall
not
postpone
the
effectiveness
of
such
rule
or
action.
This
action
may
not
be
challenged
later
in
proceedings
to
enforce
its
requirements.

SUPPLEMENTARY
INFORMATION:
In
a
final
rule
published
on
September
21,
1998
(
63
FR
50388),
EPA
established
final
effluent
limitations
and
standards
for
the
pharmaceutical
manufacturing
point
source
category
for
the
control
of
wastewater
pollutants.
The
final
rule
contained
minor
typographical
errors
and
errors
in
the
rounding
of
several
of
the
numerical
limitations
to
a
specific
number
of
significant
figures.
This
document
corrects
those
errors.

Administrative
Requirements
Under
Executive
Order
12866
(
58
FR
51735,
October
4,
1993),
this
action
is
not
a
``
significant
regulatory
action''
and
is
therefore
not
subject
to
review
by
the
Office
of
Management
and
Budget.
In
addition,
this
action
does
not
impose
any
enforceable
duty,
contain
any
unfunded
mandate,
or
impose
any
significant
or
unique
impact
on
small
governments
as
described
in
the
Unfunded
Mandates
Reform
Act
of
1995
(
Pub.
L.
104
 
4).
This
rule
also
does
not
require
prior
consultation
with
State,
local,
and
tribal
government
officials
as
specified
by
Executive
Order
12875
(
58
FR
58093,
October
28,
1993)
or
Executive
Order
13084
(
63
FR
27655,
May
10,
1998),
or
involve
special
consideration
of
environmental
justice
related
issues
as
required
by
Executive
Order
12898
(
59
FR
7629,
February
16,
1994).
Because
this
action
is
not
subject
to
the
notice­
and­
comment
requirements
under
the
Administrative
Procedure
Act,
5
U.
S.
C.
553,
or
any
other
statute,
it
is
not
subject
to
the
regulatory
flexibility
provisions
of
the
Regulatory
Flexibility
Act
(
5
U.
S.
C.
601
et
seq.).
This
rule
also
is
not
subject
to
Executive
Order
13045
(
62
FR
19885,
April
23,
1997)
because
EPA
interprets
E.
O.
13045
as
applying
only
to
those
regulatory
actions
that
are
based
on
health
and
safety
risks,
such
that
the
analysis
required
under
section
5
 
501
of
the
Order
has
the
potential
to
influence
the
regulation.
This
rule
is
not
subject
to
E.
O.
13045
because
it
does
not
establish
an
environmental
standard
intended
to
mitigate
health
or
safety
risks.
EPA's
compliance
with
these
statutes
and
Executive
Orders
for
the
underlying
rule
is
discussed
in
the
Federal
Register
notice
of
September
21,
1998.
This
action
contains
no
information
collection
requirements.
Therefore,
no
information
collection
request
has
been
submitted
to
the
Office
of
Management
and
Budget
(
OMB)
for
review
and
approval
under
the
Paperwork
Reduction
Act
of
1980,
44
U.
S.
C.
1501,
et
seq.
The
revisions
in
this
final
rule
are
not
substantive.
These
revisions
correct
minor
typographical
errors
and
errors
in
the
rounding
of
several
numerical
limitations.
For
this
reason,
EPA
has
determined
that
public
participation
in
this
action
is
unnecessary
and
constitutes
good
cause
for
issuing
this
rule
without
notice
and
comment.
For
the
same
reason,
the
Agency
has
determined
that
good
cause
exists
to
waive
the
requirement
for
a
30
day
period
before
the
amendments
become
effective
and
therefore
the
amendments
will
be
immediately
effective.
The
Congressional
Review
Act
(
CRA),
5
U.
S.
C.
801
et
seq.,
as
added
by
the
Small
Business
Regulatory
Enforcement
Fairness
Act
of
1996,
generally
provides
that
before
a
rule
may
take
effect,
the
agency
promulgating
the
rule
must
submit
a
rule
report,
which
includes
a
copy
of
the
rule,
to
each
House
of
the
Congress
and
to
the
Comptroller
General
of
the
United
States.
Section
808
allows
the
issuing
agency
to
make
a
rule
effective
sooner
than
otherwise
provided
by
the
CRA
if
the
agency
makes
a
good
cause
finding
that
notice
and
public
procedure
is
impracticable,
unnecessary
or
contrary
to
the
public
interest.
This
determination
must
be
supported
by
a
brief
statement.
5
U.
S.
C.
808(
2).
As
stated
above,
EPA
has
made
such
a
good
cause
finding,
including
the
reasons
therefor,
and
established
an
effective
date
of
March
4,
1999.
EPA
will
submit
a
report
containing
this
rule
and
other
required
information
to
the
U.
S.
Senate,
the
U.
S.
House
of
Representatives,
and
the
Comptroller
General
of
the
United
States
prior
to
publication
of
the
rule
in
the
Federal
Register.
This
action
is
not
a
``
major
rule''
as
defined
by
5
U.
S.
C.
804(
2).
