Carolina
Recommendation
for
Harnett
County
The
purpose
of
this
paper
is
to
discuss
recommending
Harnett
County
as
attainment
for
the
8­
hour
ozone
standard.

 
The
majority
of
the
NOx
emissions
in
Harnett
County
are
generated
from
mobile
and
non­
road
mobile
sources
(
9.07
tons
per
day
from
mobile
and
an
additional
3.11
tons
per
day
from
non­
road
mobile
out
of
the
total
13.20
tons
per
day).
There
is
no
major
point
source
in
Harnett
County
(
total
NOx
of
0.55
tons
per
day).
The
Federal
and
state
mobile
strategies
will
reduce
the
mobile
emissions
in
Harnett
County.
The
I/
M
program
will
be
implemented
in
Harnett
County
by
July
2004.
Low
sulfur
gasoline
will
be
required
statewide.
For
these
mobile
sources,
North
Carolina
has
already
adopted
the
only
available
strategy.
 
Harnett
County
is
relatively
rural
county
with
population
densities
typically
50­
100,
or
100­
250
persons
per
square
mile.
The
population
in
Harnett
County
grew
by
34.2%
between
1990
(
67,833
people)
and
2000
(
91,025
people),
and
is
expected
to
grow
by
28.7%
between
2000
and
2010
(
projected
117,192
people).
In
contrast,
Wake
County's
population
grew
by
47.3%
between
1990
(
426,301
people)
and
2000
(
627,846
people),
and
is
expected
to
grow
by
36.5%
between
2000
and
2010
(
projected
857,054
people).
Even
with
the
growth,
Harnett
County
still
has
relatively
lower
population
density.
 
In
conclusion,
North
Carolina
continues
to
believe
that
Harnett
County
should
not
include
as
a
nonattainment
county.
The
emissions
will
be
controlled
by
Federal
and
State
programs,
and
there
remain
no
additional
control
strategies
to
be
placed
on
the
emissions
in
Harnett
County.
