Dear
Ms.
Foss:

I
am
writing
this
letter
to
all
Region
5
States
to
reaffirm
the
United
States
Environmental
Protection
Agency's
(
USEPA)
commitment
to
ensure
the
integrity
of
the
Clean
Air
Act's
Title
V
program
and
the
permits
issued
thereunder.
It
has
come
to
our
attention
that
there
may
still
be
some
questions
regarding
the
monitoring,
record
keeping,
and
reporting
requirements
of
the
Title
V
program.

Monitoring,
record
keeping,
and
reporting
requirements
are
important
elements
of
a
technically
sound
and
enforceable
Title
V
permit.
Section
70.6(
a)(
3)
of
the
Title
V
regulations
specifies
the
standard
monitoring
and
related
record
keeping
and
reporting
requirements
that
each
Title
V
permit
must
contain.
One
important
element
of
the
monitoring,
record
keeping,
and
reporting
requirements
of
Title
V
is
that
each
permit
must
contain
periodic
monitoring
sufficient
to
yield
reliable
data
from
the
relevant
time
period
that
are
representative
of
the
source's
compliance
with
the
permit,
if
the
underlying
applicable
requirements
do
not
otherwise
specify
such
monitoring.
This
provision
is
commonly
referred
to
as
the
gap­
filling
provision.
Therefore,
if
the
underlying
applicable
requirements,
such
as
construction
permit
conditions
or
State
Implementation
Plan
requirements,
do
not
contain
adequate
monitoring,
record
keeping,
and
reporting
provisions
sufficient
to
provide
such
reliable
data,
the
State
must
add
such
provisions
in
the
Title
V
permit,
and
these
provisions
must
be
located
in
the
federally
enforceable
section
of
the
permit.
This
periodic
monitoring
requirement
is
a
Title
V
program
element,
and
it
exists
independent
of
the
USEPA's
future
actions
with
respect
to
the
Compliance
Assurance
Monitoring
regulations,
which
are
currently
under
consideration.

The
USEPA
has
not
issued
any
guidance
related
to
the
content
or
sufficiency
of
Title
V
periodic
monitoring
scenarios,
and
State
permitting
authorities
have
significant
discretion
to
tailor
the
application
of
the
gap­
filling
requirement
in
ways
that
are
effective
and
reasonable.
Nonetheless,
Title
V
does
require
that
operating
permits
include
gap­
filling
measures
where
needed.
We
have
discussed
this
matter
with
USEPA
Headquarters
offices
and
can
confirm
that
this
is
their
position
as
well.

Enclosed
are
some
excerpts
from
recent
Wisconsin
Title
V
permits
which
contain
periodic
monitoring
elements
that
meet
the
intent
of
the
Title
V
provisions.
I
am
using
examples
from
Wisconsin
as
this
State
is
the
furthest
along
in
the
actual
issuance
of
Title
V
permits
in
Region
5,
and
Wisconsin's
Title
V
permit
format
is
designed
to
assure
that
compliance
requirements
are
included.
Please
note
that
these
examples
are
provided
to
show
Wisconsin's
approach
of
addressing
the
periodic
monitoring
requirements,
and
are
not
comprehensive
of
all
the
variations
to
gap­
filling
that
are
possible
for
any
given
situation.
Also,
note
that
many
of
the
specific
Wisconsin
statutory
and
regulation
citations
in
column
B
of
these
excerpts
refer
to
the
state's
general
authority
for
establishing
gap
filling
or
expand
upon
underlying
general
monitoring
requirements.
These
permits
are
available
for
viewing
on
the
Internet
at
the
Wisconsin
Department
of
Natural
Resources
Gopher
site.

As
Region
5
works
with
its
States
to
implement
Title
V
permitting,
the
presence
of
periodic
monitoring
requirements
is
one
area
which
will
receive
Regional
review.
Any
permit
that
does
not
contain
the
periodic
monitoring
provisions
as
required
by
40
CFR
70.6
is
subject
to
an
USEPA
veto
in
accordance
with
the
objection
provisions
in
40
CFR
70.8(
c).

I
hope
this
letter
and
the
examples
I
have
provided
clarify
the
Agency's
position
that
periodic
monitoring
provisions
must
be
contained
in
all
Title
V
permits,
regardless
of
the
underlying
regulations.
If
you
or
your
staff
have
any
questions
regarding
this
information,
please
feel
free
to
contact
Rachel
Rineheart,
Minnesota
Permit
Specialist,
