Dear
Mr.
Greene:

I
am
pleased
to
enclose
the
Clean
Air
Action
Plan
(
CAAP)
for
both
the
Central
Oklahoma
and
Tulsa
Early
Action
Compacts
(
EAC).
This
submittal
is
made
in
fulfillment
of
the
March
31,
2004
milestone
outlined
in
Jeffrey
Homestead's
memo
of
November
14,
2002.

The
Air
Quality
Division
of
the
Oklahoma
Department
of
Environmental
Quality
(
DEQ)
will
continue
to
work
in
close
cooperation
with
the
Association
of
Central
Oklahoma
Governments
(
ACOG),
the
Indian
Nations
Council
of
Governments
(
INCOG),
and
our
modeling
contractor,
ENVIRON,
in
further
refining
and
developing
these
plans
with
the
goal
of
making
final
State
Implementation
Plan
(
SIP)
submittals
by
the
end
of
this
year.
The
DEQ,
ACOG,
and
INCOG
will
strive
to
meet
upcoming
EAC
milestones
even
though
current
monitoring
data
now
indicate
both
Oklahoma
City
and
Tulsa
areas
are
currently
in
attainment
with
the
8­
hour
ozone
standard,
making
non­
attainment
deferrals
unnecessary
at
this
time.

The
modeling
analyses
performed
indicate
that
the
Oklahoma
City
area
will
continue
to
attain
the
standard
by
2007,
and
weight
of
evidence
demonstrations
can
be
used
to
predict
attainment
in
Tulsa
as
well.
DEQ
plans
to
incorporate
the
Transportation
Control
Measures
recommended
by
ACOG
and
INCOG
into
our
SIP
by
the
December
31,
2004
deadline.

As
additional
support
of
the
local
control
strategies
described
in
the
CAAP,
the
Air
Quality
Division
is
pursuing
likely
state­
initiated
control
measures
that
could
be
incorporated
into
the
SIP;
especially
in
the
event
of
monitored
non­
attainment
this
summer.
Such
measures
could
include
emission
reductions
required
by
consent
orders
related
to
ongoing
enforcement
negotiations.

We
look
forward
to
working
with
your
office
on
these
important
matters.

Sincerely,

Eddie
Terrill
Director,
Air
Quality
Division
