MEMORANDUM
TO:
Docket
FROM:
EPA,
Clean
Air
Markets
Division
SUBJECT:
Correction
to
State
NOx
Budgets
Proposed
in
the
Supplemental
Notice
of
Proposed
Rulemaking
for
the
Clean
Air
Interstate
Rule
DATE:
July
23,
2004
In
the
January
30,
2004
Notice
of
Proposed
Rulemaking
(
NPR)
1,
EPA
proposed
to
distribute
the
28­
State
(
and
D.
C.)
regional
NOx
budgets
based
on
each
State's
average
heat
input
 
using
heat
input
data
from
Acid
Rain
Program
units
 
over
the
years
1999
through
2002.
EPA
summed
the
average
heat
input
from
each
of
the
applicable
jurisdictions
to
obtain
a
regional
total
average
annual
heat
input.
Then,
each
State
received
a
pro
rata
share
of
the
regional
NOx
emissions
budget
based
on
the
ratio
of
its
average
annual
heat
input
to
the
regional
total
average
annual
heat
input.

In
the
June
10,
2004
Supplemental
Notice
of
Proposed
Rulemaking
(
SNPR)
2,
EPA
again
proposed
to
apportion
state
budgets
using
heat
input,
but
to
supplement
the
Acid
Rain
Program
data
with
annual
heat
input
data
from
the
U.
S.
Energy
Information
Administration
(
EIA)
to
reflect
heat
input
from
non­
Acid
Rain
units.
Additionally,
EPA
noted
that
it
was
including
updated
Acid
Rain
Program
data
for
2002
in
the
calculation
of
state
budgets.
The
docket
contains
a
technical
support
document
and
a
memorandum
that
describe
in
detail
the
heat
input
data
used
in
the
calculation
of
state
budgets,
entitled
as
well
as
the
data
in
spreadsheet
form
(
EPA
docket
entries

2003­
0052­
1407,

and

EPA
inadvertently
made
an
error
in
the
calculation
of
state
NOx
budgets
in
the
SNPR
(
69
FR
32749­
32750).
This
memorandum
provides
revised
state
NOx
budgets.
Specifically,
EPA
is
making
the
following
revision:

The
heat
input
data
used
to
calculate
state
NOx
budgets
in
the
SNPR
included
updated
2
Acid
Rain
Program
for
2002,
but
did
not
include
the
EIA
heat
input
data
that
EPA
had
proposed
to
include
as
a
supplement
to
the
Acid
Rain
Program
data.
The
revised
state
NOx
budgets
presented
in
this
memorandum
were
calculated
using
heat
input
data
for
Acid
Rain
Program
units
for
1999­
2002,
supplemented
with
EIA
heat
input
data
to
account
for
affected
non­
Acid
Rain
Program
units.

EPA
notes
that
it
is
not
revising
the
methodology
it
proposed
to
calculate
state
NOx
budgets,
but
rather
is
making
a
revision
based
solely
on
an
error
in
applying
the
methodology.
Table
1
presents
the
state
NOx
budgets
proposed
in
the
SNPR
and
the
revised
state
budgets.

Additionally,
as
was
discussed
in
the
SNPR,
EPA
is
taking
comment
on
the
data
and
methodology
used
to
calculate
state
emission
budgets.
Any
further
changes
or
corrections
to
the
data
as
a
result
of
public
comment
would
result
in
further
revisions
to
the
state
emission
budgets.
