GENERAL

Clarification

and
Pollutant
Discharges
TOPICS
DISCUSSED
AND
ACTION
TAKEN
I
called
the
Mississippi
Phosphate
Corporation,
in
Pascagoula,
MS
and
spoke
with
Jim
Smith
on
Friday,
Jan.
16,
2004.
I
had
two
main
questions:
1)
Under
which
part
of
40
CFR
is
this
facility
regulated?
and
2)
What
affects
the
mass
of
pollutant
discharges
from
year
to
year?

Mr
Smith
was
quite
familiar
with
the
40
CFR
regulations
and
noted
that
this
facility
is
regulated
under
40
CFR
418
(
Fertilizer
Manufacturing).
He
also
mentioned
that
their
SIC
code
is
2784.
Mr.
Smith
stated
that
there
are
three
manufacturing
plants
at
this
location:
a
sulfuric
acid
plant,
a
phosphoric
acid
plant,
and
a
diammonia
phosphate
plant.
He
also
mentioned
that
they
produce
no
surperphosphates
and
no
mixed
blends.
We
discussed
each
of
the
subcategories
for
both
40
CFR
418
and
40
CFR
422
(
Phosphate
Manufacturing)
and
confirmed
that
this
facility
is
regulated
under
subcategory
A
of
40
CFR
418.
Mr.
Smith
assured
me
that
they
currently
produce
no
other
products
that
fall
under
other
categories.
In
the
past,
this
facility
used
to
produce
mixed
blends
and
was
regulated
under
both
subcategory
A
and
subcategory
G
of
40
CFR
418.
However,
the
mixed
blend
operations
ceased
before
2000.

I
also
asked
Mr.
Smith
about
their
reported
pollutant
discharges
and
why
they
fluctuate
from
year
to
year.
Mr.
Smith
explained
that
the
facility
operates
a
1.5­
MGD
treatment
system,
primarily
for
the
control
of
fluoride.
However,
the
facility
is
located
on
the
gulf
and
periodically
receives
significant
rainfall.
The
normal
annual
precipitation
for
their
area
is
around
65
inches
but
some
years
it
exceeds
100
inches.
The
wastewater
treatment
system
is
unable
to
handle
the
increased
flow
during
these
periods
of
heavy
rainfall.
The
facility's
NPDES
permit
includes
a
provision
that
allows
emergency
discharges
of
partially
treated
wastewater,
which
explains
periods
of
higher
mass
pollutant
discharge.

Mr.
Smith
also
noted
that
their
NPDES
permits
includes
limitations
on
ammonia
(
imposed
by
the
state)
and
fluoride
and
total
suspended
solids
(
federal
regulations).
