NOTE:
The
compliance
costs
for
BART
Units
were
calculated
in
the
context
of
two
scenarios.

The
first,
as
shown
above
(
Worksheet
Post­
BART­
1),
incorporates
IPM
assumptions.

The
second
scenario
(
Worksheet
Post­
BART­
2)
modifies
the
analysis
by
assuming
LSFO
(
95%
control)
for
all
units
greater
than
550
MW
with
a
sulfur
content
less
than
2%,
instead
of
LSD
(
90%
control)
as
assumed
in
the
first
scenario.
