{longname} Q21. How did EPA develop the general threshold of 25,000 metric tons of carbon dioxide equivalent (mtCO2e) per year? {longname} |
A21.
...
EPA
...
considered
...
several
...
factors
...
when
...
developing
...
the
...
reporting
...
threshold,
...
including
...
the
...
form
...
of
...
the
...
threshold
...
(e.g.,
...
emissions/year,
...
potential
...
to
...
emit,
...
capacity-based,
...
facility
...
or
...
unit
...
level).
...
EPA
...
reviewed
...
existing
...
capacity-based
...
(e.g.,
...
25
...
megawatts)
...
and
...
emissions-based
...
thresholds
...
used
...
in
...
other
...
GHG
...
emissions
...
programs
...
(e.g.,
...
California’s 25,000
...
mtCO
...
2
...
e)
...
and
...
the
...
10,000
...
mtCO
...
2
...
e
...
levels
...
used
...
in
...
some
...
voluntary
...
programs,
...
such
...
as
...
the
...
Department
...
of
...
Energy’s (DOE’s) 1605b program.
...
Based
...
on
...
our
...
review,
...
EPA
...
has
...
determined
...
that
...
the
...
selected
...
25,000
...
metric
...
ton
...
CO
...
2
...
e
...
threshold
...
will
...
cover
...
many
...
of
...
the
...
types
...
of
...
facilities
...
and
...
suppliers
...
typically
...
regulated
...
under
...
the
...
CAA,
...
while
...
appropriately
...
balancing
...
emission
...
coverage
...
and
...
burden.
...
EPA
...
estimated
...
that
...
at
...
a
...
threshold
...
of
...
25,000
...
metric
...
tons
...
of
...
mtCO
...
2
...
e/year,
...
approximately
...
10,000
...
facilities
...
and
...
85
...
percent
...
of
...
total
...
GHG
...
emissions
...
will
...
be
...
covered.
...
At
...
the
...
10,000
...
mtCO
...
2
...
e/year
...
level,
...
EPA
...
found
...
that
...
there
...
would
...
be
...
a
...
higher
...
economic
...
impact
...
on
...
small
...
businesses
...
including
...
small
...
industrial
...
facilities
...
and
...
commercial
...
buildings.
