BACKGROUND
The
Clean
Air
Act
requires
that
13
states
including
the
District
of
Columbia
submit
revisions
to
their
State
Implementation
Plans
that
will
require
major
new
and
major
modified
sources
of
volatile
organic
compounds
(
VOC)
or
nitrogen
oxides
(
NOx)
to
meet
certain
new
source
review
(
NSR)
requirements
if
they
are
located
(
or
are
proposing
to
locate)
in
the
Ozone
Transport
Region
(
OTR).

Section
184
of
the
CAA
requires
specific
additional
controls
for
all
areas
(
not
only
attainment
areas)
in
the
OTR,
but
also
established
the
Ozone
Transport
Commission
(
OTC)
for
the
purpose
of
recommending
to
EPA
regionwide
controls
affecting
all
areas
in
that
region.
The
OTR
consists
of
the
states
of
Connecticut,
Delaware,
Maine,
Maryland,
Massachusetts,
New
Hampshire,
New
Jersey,
New
York,
Pennsylvania,
Rhode
Island,
Vermont,
and
the
Consolidated
Metropolitan
Statistical
Area
that
includes
the
District
of
Columbia
and
portions
of
Virginia.
The
areas
designated
in
the
Virginia
portion
of
the
OTR
are
Arlington
County,
Fairfax
County,
Loudoun
County,
Prince
William
County,
Stafford
County,
Alexandria
City,
Fairfax
City,
Falls
Church
City,
Manassas
City,
and
Manassas
Park
City.

On
March
28,
2005,
the
Virginia
Department
of
Environmental
Quality
submitted
a
SIP
revision
approval
request
entitled
"
NSR
in
the
Ozone
Transport
Region
(
OTR)".
The
applicable
regulations
for
the
OTR
were
adopted
by
the
Virginia
State
Air
Pollution
Control
Board
on
September
29,
2004.
The
State
amended
its
regulations
to
indicate
that
areas
located
in
the
Virginia
portion
of
the
OTR
must
meet
the
requirements
of
Virginia
Code
Article

VAC
5
Chapter
80
(
Permits
for
Major
Stationary
Sources
and
Major
Modifications
Locating
in

Areas)
as
if
they
were
classified
as
moderate
nonattainment,
except
that
the
threshold
for
major
stationary
sources
of
VOCs
would
be
50
tons
instead
of
100
tons.

The
SIP
revision
provides
direction
as
to
what
State
regulations
sources
will
need
to
follow
when
they
are
either
planning
to
locate
in
or
are
already
located
in
the
Virginia
portion
of
the
OTR.

were

SUMMARY
OF
ACTION
EPA
is
proposing
to
approve
a
State
Implementation
Plan
(
SIP)
revision
submitted
by
the
Commonwealth
of
Virginia.
This
revision
pertains
to
changes
in
the
State's
regulations
that
identify
and
define
the
Ozone
Transport
Region
(
OTR)
locations
in
Virginia.
It
also
informs
sources
that
are
located
in
or
planning
to
locate
in
the
OTR
that
they
must
meet
the
requirements
of
Virginia
Code
Article
9
VAC
5
Chapter
80
(
Permits
for
Major
Stationary
Sources
and
Major
Modifications
Locating
in
Nonattainment
Areas)
as
if
they
were
classified
as
moderate
nonattainment,
except
that
the
threshold
for
major
stationary
sources
of
VOCs
would
be
50
tons
instead
of
100
tons.
The
areas
designated
in
the
Virginia
portion
of
the
OTR
are
Arlington
County,
Fairfax
County,
Loudoun
County,
Prince
William
County,
Stafford
County,
Alexandria
City,
Fairfax
City,
Falls
Church
City,
Manassas
City,
and
Manassas
Park
City.

In
addition,
this
SIP
revision
emphasizes
the
following:

1.
Counties/
Cities
in
Virginia
which
are
designated
attainment
for
ozone
and
are
located
in
the
OTR,
are
required
to
apply
new
source
requirements
to
sources
of
VOC
which
have
the
potential
to
emit
100
tons
per
year
or
more
of
nitrogen
oxides
or
50
tons
per
year
of
Volatile
Organic
Compounds.
Note
that
sources
that
are
located
in
the
OTR
and
are
designated
as
serious
or
severe
are
required
to
meet
the
more
stringent
of
emission
thresholds
listed
within
the
State`
s
definition
