Dear
Chairman
Pinto:

This
is
in
response
to
your
letter
of
May
26,
2004,
regarding
the
designation
of
the
Cuyapaipe
Indian
Reservation
under
the
8­
hour
ozone
National
Ambient
Air
Quality
Standard.
We
sincerely
apologize
for
any
confusion
the
designation
process
has
caused.
In
fact,
the
Cuyapaipe
Reservation
was
not
designated
nonattainment.
After
considering
air
quality
data
and
other
factors
used
by
EPA
to
make
designations
under
the
Clean
Air
Act
(
CAA),
we
decided
to
exclude
several
areas
in
southeastern
San
Diego
County,
including
one
that
roughly
approximates
the
boundary
of
your
reservation,
from
the
surrounding
nonattainment
area,
as
described
in
more
detail
below.

As
you
know,
on
April
15,
2004,
the
Administrator
designated
all
areas
of
the
country
with
respect
to
the
8­
hour
ozone
standard.
On
April
30,
2004,
those
designations
were
published
in
the
Federal
Register
(
see
69
FR
23858).
We
have
enclosed
two
pages
from
the
Federal
Register
final
rule
(
pages
23887
and
23890)
and
a
map
that
is
included
in
the
docket
for
our
action
and
that
illustrates
the
8­
hour
ozone
area
designation
boundaries
for
your
tribe.
Page
23887
shows
that
areas
referred
to
as
"
Cuyapaipe
Area,"
"
La
Posta
Areas
#
1
and
#
2,
"
Manzanita
Area,"
and
"
Campo
Areas
#
1
and
#
2,"
were
expressly
excluded
from
the
8­
hour
ozone
nonattainment
area
that
otherwise
encompasses
all
of
San
Diego
County.
By
excluding
those
areas
from
the
surrounding
nonattainment
area,
we
intended
to
designate
them
as
attainment/
unclassifiable
for
the
8­
hour
ozone
standard.
We
have
enclosed
page
23890
because
it
explains
that,
while
these
individual
designated
areas
roughly
approximate
the
boundaries
of
the
reservations,
they
are
not
intended
to
be
a
federal
determination
of
the
exact
boundaries
of
the
reservations.
We
hope
this
information
resolves
your
concerns
regarding
the
8­
hour
ozone
designation.
Again,
we
apologize
for
the
confusion.
If
you
have
further
questions,
or
if
you
wish
to
request
consultation,
please
contact
Steven
Barhite,
Manager
of
the
Region
9

Planning
Office,

Deborah
Jordan
Director,

Division
