RE:

Letter
Recommending
Attainment
Designation
for
Ozone
Dear
Mr.
Skinner:

Pursuant
to
Section
107(
d)(
1)
of
the
Clean
Air
Act,
and
following
the
revision
of
the
ozone
National
Ambient
Air
Quality
Standard
(
NAAQS)
on
July
18,
1997,
the
Governor
of
Minnesota
is
recommending
that
the
entire
state
of
Minnesota
be
designated
as
attainment
for
the
new
eight­
hour
ozone
standard.
This
recommendation
does
not
include
areas
within
the
state
that
are
under
tribal
jurisdiction.
Those
tribal
governments
which
have
met
eligibility
determination
and
have
submitted
a
Tribal
Implementation
Plan
to
the
U.
S.
Environmental
Protection
Agency
(
EPA)
may
submit
designation
requests
to
EPA
under
the
Tribal
Authority
Rule
of
1998
(
63
FR
7254).

This
designation
recommendation
is
based
on
three
consecutive
years
(
2000­
2002)
of
air
sampling
data
collected
at
six
federal
reference
and
equivalent
method
monitors
around
the
state.
The
summary
data
are
provided
as
tables
of
the
fourth
highest
value
at
each
monitoring
site
for
each
year
(
1993­
2002)
and
of
three­
year
calculated
averages
(
1993­
1995
through
2000­
2002)
for
each
site
(
enclosed).
No
site
in
the
state
exceeded
the
new
eighthour
standard
(
0.08
parts
per
million)
for
ozone
for
any
three­
year
period.
Quality
assured
ozone
monitoring
data
for
Minnesota
has
been
submitted
to
the
Aerometric
Information
Retrieval
System
through
2002.
The
locations
of
the
ozone
monitors
in
the
state
are
provided
by
a
map
(
enclosed).

The
Minnesota
Pollution
Control
Agency
(
MPCA)
Commissioner
is
appointed
by
the
Governor.
The
Commissioner
is
duly
authorized
to
submit
this
letter
on
behalf
of
the
Governor.
