{longname} Q553. For which units of measure are we required to calculate and report emissions using Equation W-3? May we use a flow meter to calculate annual emission CO2? {longname} |
A553.
...
The
...
units
...
of
...
measure
...
for
...
emissions
...
calculated
...
in
...
Equation
...
W-3
...
are
...
in
...
cubic
...
feet
...
per
...
year.
...
However,
...
§98.233(d)(10)
...
requires
...
that
...
the
...
volumetric
...
emissions
...
of
...
equation
...
W-3
...
be
...
converted
...
into
...
mass
...
emissions
...
using
...
§98.233(v)
...
’s methods.
...
You
...
must
...
report
...
emissions
...
in
...
metric
...
tons
...
of
...
CO2e
...
to
...
meet
...
the
...
reporting
...
requirements
...
in
...
§98.236(c)(3)(v).
...
If
...
reporters
...
use
...
the
...
methodology
...
set
...
forth
...
in
...
§98.233(d)(2),
...
then
...
a
...
vent
...
flow
...
meter
...
must
...
be
...
used
...
to
...
determine
...
the
...
total
...
annual
...
volume
...
of
...
vent
...
gas
...
flowing
...
out
...
of
...
the
...
AGR
...
unit.
