Note:
"

means
not
available
and
"
N/

means
not
calculated.
EPA
may
not
have
calculated
a
rank
due
to
lack
of
PCS
or
TRI
data
(
e.
g.,
coil
coating).
EPA
may
also
have
been
unable
to
identify
the
pollutant
loadings
for
the
various
subcategories
within
a
point
source
category.

Note:
The
TWPE
estimates
for
both
Waste
Combustors
(
Part
444)
and
Landfills
(
Part
445)
are
the
same
as
EPA
used
the
same
SIC
code
(
Refuse
Systems
(
4953))
to
estimate
loadings
for
both
categories.
