Re:
Status
of
Phosphate
Manufacturing
(
CFR
422)
Review
During
EPA's
screening
level
analysis
for
its
effluent
guidelines
program
plan
for
2004,
EPA
identified
phosphate
manufacturing
as
a
Group
III
category.
This
industry
currently
ranks
3rd
and
33rd
in
PCS
and
TRI
rankings,
respectively.
The
primary
pollutants
discharged
(
pounds
of
pollutants
collectively
discharged
in
the
highest
quantities)
by
this
industry
are
ammonia­
nitrogen,
total
sulfate,
total
phosphorus,
and
total
suspended
solids.
As
explained
in
a
separate
memo
titled
"
Description
and
Results
of
EPA
Methodology
to
Synthesize
Screening
Level
Results
for
the
ELG
Program
Plan
for
2004/
2005,"
EPA
had
concerns
that
it
may
have
included
some
facilities
in
this
category
in
error.
EPA
has
preliminarily
completed
this
review
and
the
most
recent
results
included
in
EPA's
record
reflect
this
review.

Current
results
indicate
that
a
few
facilities
are
driving
the
discharges
for
this
category.
EPA
will
continue
investigating
the
pollutant
discharges
from
these
facilities.
