SUPPLEMENTARY
INFORMATION:
As
part
of
the
2002
appropriations
process,
Congress
directed
EPA
to
``
begin
immediately
to
review
the
Agency's
affordability
criteria
and
how
small
system
variance
and
exemption
programs
should
be
implemented
for
arsenic''
(Conference
Report
107–
272,
page
175).
Congress
further
directed
the
Agency
to
prepare
a
report,
which
EPA
submitted
(Report
to
Congress:
Small
System
Arsenic
Implementation
Issues:
EPA
815–
R–
02–
003),
``
on
its
review
of
the
affordability
criteria
and
the
administrative
actions
undertaken
or
planned
to
be
undertaken
by
the
Agency,
as
well
as
potential
funding
mechanisms
for
small
community
compliance
and
other
legislative
actions,
which,
if
taken
by
the
Congress,
would
best
achieve
appropriate
extensions
of
time
for
small
communities
while
also
guaranteeing
maximum
compliance.
''
(Conference
Report
107–
272,
page
175).
In
evaluating
treatment
technologies
for
small
systems,
EPA
currently
uses
an
affordability
threshold
of
2.5%
of
median
household
income.
EPA's
national­
level
affordability
criteria
consist
of
two
major
components:
an
expenditure
baseline
and
an
affordability
threshold.
The
expenditure
baseline
(derived
from
annual
median
household
water
bills)
is
subtracted
from
the
affordability
threshold
(a
share
of
median
household
income
that
EPA
believes
to
be
a
reasonable
upper
limit
for
these
water
bills)
to
determine
the
expenditure
margin
(the
maximum
increase
in
household
water
bills
that
can
be
imposed
by
treatment
and
still
be
considered
affordable).
EPA
compares
the
cost
of
treatment
technologies
against
the
available
expenditure
margin
to
determine
if
an
affordable
compliance
technology
can
be
identified.
If
EPA
cannot
identify
an
affordable
compliance
technology,
then
it
attempts
to
identify
a
variance
technology.
Findings
must
be
made
at
both
the
Federal
and
State
level
that
compliance
technologies
are
not
affordable
for
small
systems
before
a
variance
can
be
granted.
EPA
is
asking
the
NDWAC
for
advice
on
its
national­
level
affordability
criteria
and
the
methodology
used
to
establish
these
criteria.
Taking
into
consideration
the
structure
of
the
Safe
Drinking
Water
Act
and
the
limitations
of
readily
available
data
and
information
sources,
EPA
is
seeking
the
Council's
opinion
of
the
national
level
affordability
criteria,
methodology
for
deriving
the
criteria,
and
approach
to
applying
those
criteria
to
NPDWRs.
As
part
of
the
Council's
review
of
EPA's
national­
level
affordability
criteria,
the
Agency
is
seeking
input
on
(1)
the
Agency's
overall
approach,
(2)
alternatives,
if
any,
to
the
use
of
median
household
income
as
a
metric,
(3)
alternatives,
if
any,
to
2.5%
as
a
metric,
(4)
alternatives,
if
any,
to
calculating
the
expenditure
baseline,
(5)
the
usefulness
of
a
separate
criteria
for
ground
and
surface
water
systems,
(6)
including
an
evaluation
of
the
potential
availability
of
financial
assistance,
and
(7)
the
need
for
making
affordability
determinations
on
a
regional
basis.
Other
issue
areas
may
also
be
discussed.
The
meeting
is
open
to
the
public;
statements
from
the
public
will
be
taken
at
the
close
of
the
meeting.
EPA
is
not
soliciting
written
comments
and
is
not
planning
to
formally
respond
to
comments.
This
will
be
the
third,
fourth,
and
fifth
work
group
meetings
on
this
topic.
At
the
first
meeting
held
on
September
11–
12
,
the
work
group
was
briefed
by
EPA
on
the
approach
to
affordability
taken
by
the
Agency.
At
the
first
meeting,
the
work
group
also
devised
an
approach
to
answer
the
Agency's
charge
questions.
For
the
second
work
group
meeting
(to
be
held
on
October
21–
22),
other
technical
experts
on
financial
assistance
have
been
invited
to
speak.
The
purpose
of
these
last
three
meetings
is
to
continue
the
workgroup
deliberations
and
to
draft
a
report
for
the
full
National
Drinking
Water
Advisory
Council.

A.
Residue
Chemistry
1.
Plant
metabolism.
Like
any
other
carbohydrate,
HSH
degrades
readily
in
the
soil
and
other
substrates
into
carbon
dioxide
and
water.
HSH
(CAS
number
68425–
17–
2)
is
a
carbohydrate
polymer
with
a
theoretical
molecular
weight
(in
amu)
of
1,000–
3,600.
It
can
be
supplied
as
a
liquid
syrup
or
white
powder.
The
empirical
formula
of
the
components
of
HSH
are:

Components
Formula
Sorbitol
C6H14O6
Maltitol
C12H24O11
Hydrogenated
polysaccharides
C12H24O11
plus
C6H10O5
for
each
additional
glucose
moiety
in
the
chain
HSH
is
highly
soluble
in
water.
The
aqueous
solution
has
a
pH
range
of
4.0–
6.0.
It
hydrolyzes
slowly
to
glucose
and
sorbitol.
It
combusts
at
300
0
C
to
carbon
dioxide
and
water.
2.
Analytical
method.
The
qualitative
analysis
of
HSH
in
the
products
to
which
it
has
been
added
may
be
accomplished
by
extraction
of
the
sorbitol
and
maltitol
moieties
with
appropriate
solvents,
followed
by
gas
chromatography
of
the
extracts.
Similarly,
the
quantity
of
HSH
occurring
in
food
may
be
estimated
by
determining
the
amount
of
maltitol
recovered
and
applying
an
appropriate
factor.
Information
on
the
sensitivity
and
reproducibility
of
the
method
has
also
been
developed.
3.
Magnitude
of
residues.
HSH
is
readily
degraded
by
microorganisms
on
leaf
surfaces
and
in
the
soil.
Due
to
the
solubility
of
this
carbohydrate,
rain,
or
other
water
sources
wash
the
carbohydrate
into
the
soil
where
it
is
degraded
by
microorganisms
into
carbon
dioxide
and
water.
No
harmful
residues
are
produced.
B.
Toxicological
Profile
HSH
has
been
widely
used
in
foods
since
the
early
1980s.
It
has
been
marketed
extensively
by
Roquette,
Lonza
and
SPI
Polyols
for
years.
Grain
Processing
Corporation
produces
HSH
using
a
process
that
is
equivalent
to
the
process
petitioned
to
the
Food
and
Drug
Administration
by
Lonza
and
Roquette
Freres
for
GRAS
(generally
recognized
as
safe)
affirmation.
In
support
of
the
safety
of
our
HSH,

Processing
Corporation
and

Notices
submitted
by
Roquette
in
its
Lycasin
80/
55
petition
regarding
numerous
studies
relating
to
the
safety
of
the
ingredient,
including
reports
on:
Digestion,
absorption,
distribution
and
excretion;
acute
oral
toxicity,
subchronic
toxicity,
genotoxicity,
reproduction,
biological
tolerance,
human
exposure,
and
laxation
effects.
1.
Acute
toxicity.
The
acute
oral
toxicity
of
HSH
has
been
evaluated.
The
acute
oral
lethal
dose
(LD50)
of
HSH
is
greater
than
10
grams/
kilogram
(g/
kg).
2.
Genotoxicty.
As
stated
in
Roquette's
GRAS
submission
of
Lycasin
80/
55,
HSH
is
nonmutagenic
and
nonclastogenic
in
short­
term
in
vivo,
and
in
vitro
studies.
3.
Reproductive
and
developmental
toxicity.
Again
as
noted
in
Roquette's
GRAS
submission
of
Lycasin
80/
55
HSH
products,
when
administered
to
rats
over
3­
generations,
produce
no
significant
effects
on
reproduction.
4.
Subchronic
toxicity.
In
Roquette's
GRAS
submission
for
Lycasin
80/
55,
it
is
noted
that
when
administered
orally
to
rats
and
dogs
in
amounts
of
5
g/
kg
to
15
g/
kg
of
body
weight
per
day
for
90
days,
HSH
produced
no
toxicologically
meaningful
effects
which
could
not
be
accounted
for
by
the
presence
of
sorbitol.
The
possible
treatment
related
effects
are
aggregates
in
the
renal
pelvis
of
some
rats,
diarrhea
in
most
dogs,
and
minimal
ectasia
in
the
renule
tubules
of
some
dogs.
5.
Chronic
toxicity.
HSH
is
used
extensively
in
foods.
Grain
Processing
Corporation
is
not
aware
of
any
chronic
toxic
effects
associated
with
this
product.
6.
Animal
metabolism.
The
GRAS
submission
for
Lycasin
80/
55
developed
by
Roquette
Freres
states
that
over
96%
of
HSH
(Lycasin
80/
55)
is
broken
down
by
the
mammalian
digestive
system
into
the
GRAS
substances,
glucose
and
sorbitol,
the
remaining
4%
is
in
the
form
of
maltitol.
One
half
of
the
maltitol
is
excreted
in
the
feces
and
the
majority
of
the
remainder
is
excreted
in
the
urine.
Within
the
first
2
hours
after
oral
administration
of
HSH
(Lycasin
80/
55),
virtually
all
of
the
glucose
to
glucose
bonds
are
broken
down
in
the
digestive
system,
producing
a
resulting
mixture
of
glucose,
sorbitol,
and
maltitol.
Within
7
hours,
95%
of
the
total
maltitol,
is
broken
down
into
glucose
and
sorbitol.
Of
the
remaining
5%
of
maltitol,
2%
is
found
in
the
digestive
tube
and
fecal
contents,
less
than
1%
is
found
in
the
plasma,
and
approximately
1%
is
excreted
in
the
urine.
There
is
no
accumulation
of
maltitol
in
the
plasma,
liver,
kidneys,
or
spleen
of
rats
fed
13.5
g/
kg/
day
of
Lycasin
80/
55
for
10
days
irrespective
of
whether
measurements
are
made
12
hours
or
10
days
after
cessation
of
dosing.
Lycasin
80/
55
at
the
dose
levels
tested,
30
to
180
grams
per
day,
produces
no
significant
variations
in
the
clinical
chemical,
hematological
or
urinary
profile
of
humans
with
the
exception
of
glucose
and
insulin
peaks
which
are
less
than
50%
of
those
produced
by
equivalent
amounts
of
glucose,
and
50
to
90%
of
those
produced
by
sucrose.
The
only
significant
clinical
effects
are
flatulence
and
diarrhea,
which
can
be
accounted
for
by
the
presence
of
free
and
bound
sorbitol.
The
mean
laxative
threshold
in
adult
males
is
approximately
180
grams
per
day,
while
in
females
the
threshold
is
approximately
100
grams
per
day.
In
children,
the
threshold
is
approximately
60
grams
per
day,
about
half
that
of
adults.
7.
Metabolite
toxicology.
None
of
the
metabolites
of
HSH
are
considered
to
be
of
toxicological
significance
for
the
use
of
this
product
as
a
pesticide
inert
ingredient.
8.
Endocrine
disruption.
Grain
Processing
Corporation
is
not
aware
of
any
endocrine
disruption
with
the
use
of
this
product.

C.
Aggregate
Exposure
1.
Dietary
exposure.
This
product
is
already
used
extensively
in
foods.
Studies
have
shown
that
it
is
safe
even
when
consumed
at
levels
of
up
to
100
g/
day.
i.
Food.
As
a
pesticide
inert
ingredient
HSH
will
not
result
in
any
harmful
exposure.
The
proposed
use
will
not
result
in
any
dietary
exposure
beyond
what
is
currently
present
in
commonly
consumed
foods.
ii.
Drinking
water.
There
is
no
anticipated
human
exposure
to
HSH
through
drinking
water.
HSH
is
expected
to
be
degraded
by
soil
microorganisms
to
carbon
dioxide
and
water
before
it
reaches
surface
or
ground
water.
Moreover,
in
water,
HSH
hydrolyses
to
glucose
and
sorbitol.
2.
Non­
dietary
exposure.
No
significant
non­
dietary
human
exposure
to
HSH
is
anticipated.

D.
Cumulative
Effects
HSH
is
a
widely
used
food
ingredient,
is
readily
digested
by
humans,
and
there
are
no
cumulative
effects.
Except
for
possible
occupational
exposure
of
the
pesticide
mixer/
loader/
applicator,
the
proposed
use
of
HSH
will
not
result
in
the
exposure
of
other
persons.
E.
Safety
Determination
1.
U.
S.
population.
The
proposed
use
of
HSH
does
not
pose
a
safety
concern
for
the
U.
S.
population
due
to
the
nontoxic
nature
of
the
compound
and
the
absence
of
exposure.
2.
Infants
and
children.
Infants
and
children
will
not
be
exposed
to
HSH
from
its
proposed
use
as
a
pesticide
inert
ingredient.

F.
International
Tolerances
Grain
Processing
Corporation
is
unaware
of
any
international
tolerances
for
this
product.
HSH
was
developed
by
a
Swedish
company
in
the
1960's
and
has
been
widely
used
by
the
food
industry
for
many
years,
especially
in
confectionery
products.
Roquette's
