The
following
tables
present
EPA's
national
air
pollutant
emission
estimates
through
the
year
2001.
This
in
purpose
of
general
public
understanding.

This
information
was
previously
released
in
the
form
of
tables
in
Appendix
A
of
the
annual
report
titled
"
Na
Emissions
Trends
Report".
The
most
recent
of
these
reports
was
for
the
year
1999
and
is
available
at
http://
www.
epa.

oar/
aqtrnd99/.
The
following
tables
both
extend
the
estimates
to
2001
and
introduce
re
reported.

The
revisions
to
previous
estimates
are
all
related
to
the
development
of
the
1999
National
Emissions
Inve
estimates
in
these
tables
are
taken
from
version
2
of
the
1999
NEI,
and
reflect
many
new
submissions
of
d
management
agencies,
especially
for
industrial
point
sources
but
also
for
non­
point
source
categories
for
of
1999
emissions
from
mobile
sources
are
in
most
cases
based
on
the
new
MOBILE6
and
the
draft
NONR
models.
This
is
the
first
time
that
estimates
using
these
models
have
appeared
in
this
format.
Some
but
r
estimates
were
provided
by
state
air
agencies.
The
largest
set
of
state­
submitted
data
in
1999
was
from
C
documentation
of
the
1999
estimates

be

1999
Estimates
for
2000
and
2001
have
in
most
cases
been
made
using
methods
and
data
consistent
with
the
n
example,
point
and
non­
point
stationary
emissions
have
been
projected
forward
from
the
1999
estimates
b
factors.
An
exception
to
consistency
is
that
no
state­
submitted
data
on
mobile
sources
is
reflected
in
the
n
2001,
even
if
state­
submitted
data
was
available
and
was
used
for
1999.
The
largest
set
of
state­
submitte
California.
Because
of
the
size
of
the
California
vehicle
fleet,
the
difference
in
data
sources
for
1999
vs.
2
significant
even
when
emissions
are
presented
as
national
totals.
A
future
version
of
these
tables
will
atte
inconsistency.

Estimates
for
mobile
sources
for
years
prior
to
1999
have
been
made
consistently
with
the
estimates
for
19
generally
consistent
time
trend
except
that
state­
submitted
data
has
been
incorporated
only
for
1999.

Estimates
for
non­
mobile
sources
prior
to
1999
have
in
general
not
been
revised
since
their
last
publication
Emissions
Trends
Report
­
1999".
Appendix
B
of
that
report
explains
the
more
notable
of
the
differences
i
have
accumulated
in
these
estimates,
which
make
it
necessary
to
be
cautious
when
interpreting
apparent
source
categories.

At
the
time
of
posting
of
these
tables,
the
EPA
AirData
website
http://

has

Accordingly,
there
will
be
inconsistencies
in

via

particularly
for
mobile
sources.
The

Note(
s):
NA
=
not
available.
For
several
source
categories,
emissions
either
prior
to
or
beginning
with
1985
are
not
available
at
the
more
detailed
level
but
are
contained
in
the
more
aggregate
estimate.

One
short
ton
=
2,000
pounds.

"
Other"
categories
may
contain
emissions
that
could
not
be
accurately
allocated
to
specific
source
categories.

Zero
values
represent
less
than
500
short
tons/
year.

In
order
to
convert
emissions
to
gigagrams
(
thousand
metric
tons),
multiply
the
above
values
by
0.9072.

Some
columns
may
not
sum
to
totals
due
to
rounding.

Note(

not
available.
For
several
source
categories,
emissions
either
prior
to
or
beginning
with
1985
are
not
available
at
the
more
detailed
level
but
are
contained
in
the
more
aggregate
estimate.

One
short
ton
=
2,000
pounds.

"
Other"
categories
may
contain
emissions
that
could
not
be
accurately
allocated
to
specific
source
categories.

Zero
values
represent
less
than
500
short
tons/
year.

In
order
to
convert
emissions
to
gigagrams
(
thousand
metric
tons),
multiply
the
above
values
by
0.9072.

Some
columns
may
not
sum
to
totals
due
to
rounding.

Note(

not
available.
For
several
source
categories,
emissions
either
prior
to
or
beginning
with
1985
are
not
available
at
the
more
detailed
level
but
are
contained
in
the
more
aggregate
estimate.

One
short
ton
=
2,000
pounds.

"
Other"
categories
may
contain
emissions
that
could
not
be
accurately
allocated
to
specific
source
categories.

Zero
values
represent
less
than
500
short
tons/
year.

No
data
was
available
after
1984
to
weigh
the
emissions
from
residential
wood
burning
devices.

In
order
to
convert
emissions
to
gigagrams
(
thousand
metric
tons),
multiply
the
above
values
by
0.9072.

Some
columns
may
not
sum
to
totals
due
to
rounding.

One
short
ton
=
2,000
pounds.

Except
for
residential
wood
combustion,
combustion
source
emissions
for
1999­
2001
include
both
the
condensible
and
filterable
PM
fractions;

emissions
prior
to
1999
include
only
the
filterable
PM
fraction.
Residential
wood
combustion
emissions
include
both
the
condensible
and
filterable
PM
fractions
for
all
years.

"
Other"
categories
may
contain
emissions
that
could
not
be
accurately
allocated
to
specific
source
categories.

Zero
values
represent
less
than
500
short
tons/
year.

In
order
to
convert
emissions
to
gigagrams
(
thousand
metric
tons),
multiply
the
above
values
by
0.9072.

Some
columns
may
not
sum
to
totals
due
to
rounding.

Note(
s):
NA
=
not
available.
For
several
source
categories,
emissions
either
prior
to
or
beginning
with
1985
are
not
available
at
the
more
detailed
level
but
are
contained
in
the
more
aggregate
estimate.

One
short
ton
=
2,000
pounds.

Except
for
residential
wood
combustion,
combustion
source
emissions
for
1999­
2001
include
both
the
condensible
and
filterable
PM
fractions;

emissions
prior
to
1999
include
only
the
filterable
PM
fraction.
Residential
wood
combustion
emissions
include
both
the
condensible
and
filterable
PM
fractions
for
all
years.

"
Other"
categories
may
contain
emissions
that
could
not
be
accurately
allocated
to
specific
source
categories.

Zero
values
represent
less
than
500
short
tons/
year.

No
data
was
available
after
1984
to
weigh
the
emissions
from
residential
wood
burning
devices.

In
order
to
convert
emissions
to
gigagrams
(
thousand
metric
tons),
multiply
the
above
values
by
0.9072.

Some
columns
may
not
sum
to
totals
due
to
rounding.

Note(
s):
NA
=
not
available.
For
several
source
categories,
emissions
either
prior
to
or
beginning
with
1985
are
not
available
at
the
more
detailed
level
but
are
contained
in
the
more
aggregate
estimate.

One
short
ton
=
2,000
pounds.

"
Other"
categories
may
contain
emissions
that
could
not
be
accurately
allocated
to
specific
source
categories.

Zero
values
represent
less
than
500
short
tons/
year.

The
1985
fuel
combustion,
electric
utility
category
is
based
on
the
National
Allowance
Data
Base
Version
2.11,
Acid
Rain
Division,
U.
S.
EPA,
released
March
23,
1993.
Allocations
at
the
Tier
3
levels
are
approximations
only
and
are
based
on
the
methodology
described
in
section
6.0,
paragraph
6.2.1.1.

In
order
to
convert
emissions
to
gigagrams
(
thousand
metric
tons),
multiply
the
above
values
by
0.9072.

Some
columns
may
not
sum
to
totals
due
to
rounding.

One
short
ton
=
2,000
pounds.

"
Other"
categories
may
contain
emissions
that
could
not
be
accurately
allocated
to
specific
source
categories.

Zero
values
represent
less
than
500
short
tons/
year.

In
order
to
convert
emissions
to
gigagrams
(
thousand
metric
tons),
multiply
the
above
values
by
0.9072.

Some
columns
may
not
sum
to
totals
due
to
rounding.
