For

stationary
...
combustion
...
units
...
that
...
operate
...
only
...
on
...
landfill
...
gas
...
and
...
that
...
are
...
located
...
at
...
landfills,
...
CO2
...
and
...
N2O
...
emissions
...
must
...
be
...
reported
...
under
...
subpart
...
C.
...
Although
...
subpart
...
C
...
provides
...
a
...
calculation
...
methodology
...
for
...
CH4
...
emissions,
...
CH4
...
emissions
...
from
...
landfill
...
gas
...
units
...
located
...
at
...
landfills
...
are
...
already
...
calculated
...
and
...
reported
...
under
...
subpart
...
HH.
...
For
...
these
...
units,
...
no
...
CH4
...
emissions
...
need
...
to
...
be
...
reported
...
in
...
subpart
...
C
...
since
...
they
...
are
...
already
...
included
...
in
...
subpart
...
HH.
...
Also
...
note
...
that
...
not
...
all
...
destruction
...
devices
...
as
...
defined
...
in
...
subpart
...
HH
...
are
...
considered
...
stationary
...
combustion
...
units
...
in
...
subpart
...
C.
...
If
...
a
...
destruction
...
device
...
required
...
to
...
report
...
CH4
...
emissions
...
in
...
subpart
...
HH
...
is
...
considered
...
a
...
flare
...
according
...
to
...
the
...
definition
...
of
...
flare
...
provided
...
in
...
40
...
CFR
...
98.6,
...
you
...
would
...
not
...
need
...
to
...
calculate
...
CO2
...
and
...
N2O
...
emissions
...
for
...
the
...
flare
...
in
...
subpart
...
C.
...
The
...
same

principle

applies

to

other

units

exempted

from

subpart
...
C

in
