will
strengthen
and
improve
the
existing
regulation
and
make
appropriate
revisions
of
the
State's
water
quality
standards
in
accordance
with
Section
303(
c)(
2)(

of
the
Federal
Clean
Water
Act
(
CWA).
Section
303(

requires
that
South
Carolina=
s
water
quality
standards
be
reviewed
and
revised,
where

for
the
purposes
of
considering
the
Environmental
Protection
Agency=
s
(
EPA)
most
recently
published
numeric
and
narrative
criteria
and
to
comply
with
recent
Federal
regulatory
revisions
and
recommendations.
The
Department
has
also
included
two
revisions
that
will
improve
the
regulation.
R.
61­

revisions
due
to
recodification
of
additional
language
from
the
proposed
text
changes
so
that
every

Discussion
of
Revisions
as
Proposed
by
the
Department:

(
1):
Adoption
of
federal
toxics
criteria
to
reflect
the
most
current
final
published
criteria
according
to
Sections
304(
a)
and
307(
a)
of
the
Clean
Water
Act.

SECTION
REVISION
Appendix
These
revisions
reflect
EPA's
most
recently
published
criteria.
This
included
several
human
health
values
being
revised
to
adjust
for
a
higher
fish
tissue
consumption
rate
and
several
pollutant
values
that
no
longer
use
a
bioconcentration
factor,
but
now
use
a
bioaccumulation
factor.
EPA's
revised
criteria
also
included
the
footnotes
as
well
as
several
of
the
Federal
Register
citations.
The
Department
has
removed
the
proposed
methylmercury
criterion
for
human
health
and
replaced
it
with
the
current
state
water
quality
criterion
and
amended
the
footnotes
to
reflect
the
change.
The
Department
also
corrected
an
error
in
the
table
based
on
commenter's
note.

(

Review
and
revision
of
the

add
in
alpha­
numeric
order,
new
definition
for
Variance
to

The
classes
and
standards
described
in
Section
G
and
H
of
this
regulation
implement
the
above
State
policy
by
protecting
the
waters
of
South
Carolina.
Consistent
with
the
above
policy,
the
Department
adopts
the
following
general
standards
in
items
3­
17
for
all
waters
of
South
Carolina.

At
R.

add
new
subsections
to

7.
Before
the
Department
may
grant
a
variance
for
any
water
of
the
State,
there
must
be
a
demonstration
that
one
of
the
following
factors
for
reclassifying
uses
has
been
satisfied:

a.
Natural
conditions
prevent
the
attainment
of
the
use;
or
b.
Natural,
ephemeral,
intermittent,
low
flow
conditions,
or
water
levels
prevent
the
attainment
of
the
use;
or
c.
Human
caused
conditions
or
sources
prevent
the
attainment
of
the
use
and
cannot
be
remedied
or
would
cause
more
environmental
damage
to
correct
than
to
leave
in
place;
or
d.
Dams,
diversions,
or
other
types
of
hydrologic
modifications
preclude
the
attainment
of
the
use,
and
it
is
not
feasible
to
restore
the
waterbody
to
its
original
condition
or
to
operate
such
modification
in
a
way
that
would
result
in
the
attainment
of
the
use;
or
e.
Physical
conditions
related
to
the
natural
features
of
the
water
body,
such
as
the
lack
of
a
proper
substrate,
cover,
flow,
depth,
pools,
riffles,
and
the
like,
preclude
attainment
of
aquatic
life
protection
uses;
or
f.
Controls
more
stringent
than
those
required
by
Sections
301(
b)
and
306
of
the
Clean
Water
Act
would
result
in
adverse
social
and
economic
impact,
disproportionate
to
the
benefits
to
the
public
health,
safety
or
welfare
as
a
result
of
maintaining
the
standard.

8.
If
the
demonstration
necessary
under
Section
E.
7
above
has
been
satisfied,
the
Department
may
then
grant
a
variance
provided
the
following
apply:

a.
The
variance
is
granted
to
an
individual
discharger
for
a
specific
pollutant(
s)
or
parameter(
s)
and
does
not
otherwise
modify
water
quality
standards;
and
b.
The
variance
identifies
and
justifies
the
criterion
that
shall
apply
during
the
existence
of
the
variance;
and
c.
The
variance
is
established
as
close
to
the
underlying
criterion
as
is
possible
and
upon
expiration
of
the
variance,
the
underlying
criterion
shall
become
the
effective
water
quality
standard
for
the
waterbody;
and
d.
The
variance
is
reviewed
every
three
years,
at
a
minimum,
and
extended
only
where
the
conditions
for
granting
the
variance
still
apply;
and
e.
The
variance
does
not
exempt
the
discharger
from
compliance
with
any
applicable
technology
or
other
water
quality­
based
permit
effluent
limitations;
and
f.
The
variance
does
not
affect
permit
effluent
limitations
for
other
dischargers.

A
This
water
quality
criterion
was
derived
from
data
for
arsenic
(
III),
but
is
applied
here
to
total
arsenic,
which
might
imply
that
arsenic
(
III)
and
arsenic
(
V)
are
equally
toxic
to
aquatic
life
and
that
their
toxicities
are
additive.
In
the
arsenic
criteria
document
(
EPA
440/
5­
84­
033,
January
1985),
Species
Mean
Acute
Values
are
given
for
both
arsenic
(
III)
and
arsenic
(
V)
for
five
species
and
the
ratios
of
the
SMAVs
for
each
species
range
from
0.6
to
1.7.
Chronic
values
are
available
for
both
arsenic
(
III)
and
arsenic
(
V)
for
one
species;
for
the
fathead
minnow,
the
chronic
value
for
arsenic
(
V)
is
0.29
times
the
chronic
value
for
arsenic
(
III).
No
data
are
known
to
be
available
concerning
whether
the
toxicities
of
the
forms
of
arsenic
to
aquatic
organisms
are
additive.

B
This
criterion
has
been
revised
to
reflect
The
Environmental
Protection
Agency's
q1*
or
RfD,
as
contained
in
the
Integrated
Risk
Information
System
(
IRIS)
as
of
May
17,
2002.
The
fish
tissue
bioconcentration
factor
(
BCF)
from
the
1980
Ambient
Water
Quality
Criteria
document
was
retained
in
each
case.

C
This
criterion
is
based
on
carcinogenicity
of
10­
6
risk.
As
prescribed
in
Section
E
of
this
regulation,
application
of
this
criterion
for
permit
effluent
limitations
requires
the
use
annual
average
flow
or
comparable
tidal
condition
as
determined
by
the
Department.

D
Freshwater
and
saltwater
criteria
for
metals
are
expressed
in
terms
of
total
recoverable
metals.
As
allowed
in
Section
E
of
this
regulation,
these
criteria
may
be
expressed
as
dissolved
metal
for
the
purposes
of
deriving
permit
effluent
limitations.
The
dissolved
metal
water
quality
criteria
value
may
be
calculated
by
using
these
304(
a)
aquatic
life
criteria
expressed
in
terms
of
total
recoverable
metal,
and
multiplying
it
by
a
conversion
factor
(
CF).
The
term
"
Conversion
Factor"
(
CF)
represents
the
conversion
factor
for
converting
a
metal
criterion
expressed
as
the
total
recoverable
fraction
in
the
water
column
to
a
criterion
expressed
as
the
dissolved
fraction
in
the
water
column.
(
Conversion
Factors
for
saltwater
CCCs
are
not
currently
available.
Conversion
factors
derived
for
saltwater
CMCs
have
been
used
for
both
saltwater
CMCs
and
CCCs).

and
40CFR
§
131.36(
b)(
1).
Conversion
Factors
can
be
found
in
Attachment
1
 
Conversion
Factors
for
Dissolved
Metals.

E
The
freshwater
criterion
for
this
metal
is
expressed
as
a
function
of
hardness
(
mg/
L)
in
the
water
column.
The
value
given
here
corresponds
to
a
hardness
of
25
mg/
L
as
expressed
as
CaCO3.
Criteria
values
for
other
hardness
may
be
calculated
from
the
following:
CMC
(
dissolved)
=
exp{
mA
[
ln(
hardness)]+
bA}
(
CF),
or
CCC
(
dissolved)
=
exp{
mC
[
ln
(
hardness)]+
bC}
(
CF)
and
the
parameters
specified
in
Attachment
2
 
Parameters
for
Calculating
Freshwater
Dissolved
Metals
Criteria
That
Are
Hardness­
Dependent.
As
noted
in
footnote
D
above,
the
values
in
this
appendix
are
expressed
as
total
recoverable,
the
criterion
may
be
calculated
from
the
following:
CMC
(
total)
=
exp{
mA
[
ln(
hardness)]+
bA},
or
CCC
(
total)
=
exp{
mC
[
ln
(
hardness)]+
bC}.

F
Freshwater
aquatic
life
values
for
pentachlorophenol
are
expressed
as
a
function
of
pH,
and
are
calculated
as
follows:
CMC
=
exp(
1.005(
pH)­
4.869);
CCC
=
exp(
1.005(
pH)­
5.134).
Values
displayed
in
table
correspond
to
a
pH
of
7.8.

G
This
criterion
is
based
on
304(
a)
aquatic
life
criterion
issued
in
1980,
and
was
issued
in
one
of
the
following
documents:
Aldrin/
Dieldrin
(
EPA
440/
5­
80­
019),
Chlordane
(
EPA
440/
5­
80­
027),
DDT
(
EPA
440/
5­
80­
038),

Endosulfan
(
EPA
440/
5­
80­
046),
Endrin
(
EPA
440/
5­
80­
047),
Heptachlor
(
440/
5­
80­
052),
Hexachlorocyclohexane
(
EPA
440/
5­
80­
054),
Silver
(
EPA
440/
5­
80­
071).
The
Minimum
Data
Requirements
and
derivation
procedures
were
different
in
the
1980
Guidelines
than
in
the
1985
Guidelines.
For
example,
a
"
CMC"
derived
using
the
1980
Guidelines
was
derived
to
be
used
as
an
instantaneous
maximum.
If
assessment
is
to
be
done
using
an
averaging
period,
the
values
given
should
be
divided
by
2
to
obtain
a
value
that
is
more
comparable
to
a
CMC
derived
using
the
1985
Guidelines.

H
No
criterion
for
protection
of
human
health
from
consumption
of
aquatic
organisms
excluding
water
was
presented
in
the
1980
criteria
document
or
in
the
1986
Quality
Criteria
for
Water.
Nevertheless,
sufficient
information
was
presented
in
the
1980
document
to
allow
the
calculation
of
a
criterion,
even
though
the
results
of
such
a
calculation
were
not
shown
in
the
document.

I
This
criterion
for
asbestos
is
the
Maximum
Contaminant
Level
(
MCL)
developed
under
the
Safe
Drinking
Water
Act
(
SDWA)
and
the
National
Primary
Drinking
Water
Regulation
(
NPDWR).

J
EPA
has
not
calculated
a
304(
a)
human
health
criterion
for
this
contaminant.
The
criterion
is
the
Maximum
Contaminant
Level
developed
under
the
Safe
Drinking
Water
Act
(
SDWA)
and
the
National
Primary
Drinking
Water
Regulation
(
NPDWR).

K
This
criterion
is
based
on
a
304(
a)
aquatic
life
criterion
that
was
issued
in
the
1995
Updates:
Water
Quality
Criteria
Documents
for
the
Protection
of
Aquatic
Life
in
Ambient
Water,
(
EPA­
820­
B­
96­
001,
September
1996).
This
value
was
derived
using
the
GLI
Guidelines
(
60FR15393­
15399,
March
23,
1995;
40CFR132
Appendix
A);
the
difference
between
the
1985
Guidelines
and
the
GLI
Guidelines
are
explained
on
page
iv
of
the
1995
Updates.
None
of
the
decisions
concerning
the
derivation
of
this
criterion
were
affected
by
any
considerations
that
are
specific
to
the
Great
Lakes.

L
The
CMC
=
1/[(
f1/
CMC1)
+
(
f2/
CMC2)]
where
f1
and
f2
are
the
fractions
of
total
selenium
that
are
treated
as
selenite
and
selenate,
respectively,
and
CMC1
and
CMC2
are
185.9

g
/
l
and
12.82

g
/
l,
respectively.

M
This
criterion
applies
to
total
PCBs,
(
e.
g.,
the
sum
of
all
congener
or
all
isomer
or
homolog
or
Aroclor
analyses.)

N
The
derivation
of
the
CCC
for
this
pollutant
did
not
consider
exposure
through
the
diet,
which
is
probably
important
for
aquatic
life
occupying
upper
trophic
levels.

O
This
state
criterion
is
also
based
on
a
total
fish
consumption
rate
of
0.0175
kg/
day.

P
This
water
quality
criterion
is
expressed
as

g
free
cyanide
(
as
CN)/
L.

Q
This
value
was
announced
(
61FR58444­
58449,
November
14,
1996)
as
a
proposed
GLI
303
I
aquatic
life
criterion
R
This
water
quality
criterion
for
arsenic
refers
to
the
inorganic
form
only.

S
This
water
quality
criterion
for
selenium
is
expressed
in
terms
of
total
recoverable
metal
in
the
water
column.
It
is
scientifically
acceptable
to
use
the
conversion
factor
(
0.996
 
CMC
or
0.922
 
CCC)
that
was
used
in
the
GLI
to
convert
this
to
a
value
that
is
expressed
in
terms
of
dissolved
metal.

T
The
organoleptic
effect
criterion
is
more
stringent
than
the
value
for
priority
toxic
pollutants.

U
This
value
was
derived
from
data
for
heptachlor
and
the
criteria
document
provides
insufficient
data
to
estimate
the
relative
toxicities
of
heptachlor
and
heptachlor
epoxide.

V
There
is
a
full
set
of
aquatic
life
toxicity
data
that
show
that
DEHP
is
not
toxic
to
aquatic
organisms
at
or
below
its
solubility
limit.

W
This
value
was
derived
from
data
for
endosulfan
and
is

This
criterion
is
based
on
a
304(

aquatic
life
criterion
issued
in

or
1986,
and
was
issued
in

This
CCC
is
based
on
the
Final

procedure
in
the
1985
Guidelines.
Since
the
publication
of
the
Great
Lakes
Aquatic
Life
Criteria
Guidelines
in
1995
(
60FR15393­
15399,
March

the
EPA
no
longer
uses
the
Final

for
deriving
CCCs
for
new

Y
This
water
quality
criterion
is
based
on
a
304(

aquatic
life
criterion
that
was
derived
using
the
1985
Guidelines
(

Criteria
for
the
Protection
of

and

PB85­
227049,

and
was
issued
in

of
the
following
criteria
documents:
Arsenic
(

Z
When
the
concentration
of
dissolved
organic
carbon
is
elevated,
copper
is
substantially
less
toxic
and
use
of
Water­
Effect
Ratios
might
be
appropriate.

aa
The
selenium
criteria
document
(
EPA
440/
5­
87­
006,
September
1987)
provides
that
if
selenium
is
as
toxic
to
saltwater
fishes
in
the
field
as
it
is
to
freshwater
fishes
in
the
field,
the
status
of
the
fish
community
should
be
monitored
whenever
the
concentration
of
selenium
exceeds
5.0

g/
L
in
salt
water
because
the
saltwater
CCC
does
not
take
into
account
uptake
via
the
food
chain.

bb
This
water
quality
criterion
was
derived
on
page
43
of
the
mercury
criteria
document
(
EPA
440/
5­
84­
026,
January
1985).
The
saltwater
CCC
of
0.025
ug/
L
given
on
page
23
of
the
criteria
document
is
based
on
the
Final
Residue
value
procedure
in
the
1985
Guidelines.
Since
the
publication
of
the
Great
Lakes
Aquatic
Life
criteria
Guidelines
in
1995
(
60FR15393­
15399,
March
23,
1995),
the
EPA
no
longer
uses
the
Final
Residue
value
procedure
for
deriving
CCCs
for
new
or
revised
304(
a)
aquatic
life
criteria.

cc
This
water
quality
criterion
was
derived
in
Ambient
Water
Quality
Criteria
Saltwater
Copper
Addendum
(
Draft,
April
14,
1995)
and
was
promulgated
in
the
Interim
Final
National
Toxics
Rule
(
60FR22228­
222237,

May
4,
1995).

dd
This
water
quality
criterion
was
derived
from
data
for
inorganic
mercury
(
II),
but
is
applied
here
to
total
mercury.
If
a
substantial
portion
of
the
mercury
in
the
water
column
is
methylmercury,
this
criterion
will
probably
be
under
protective.
In
addition,
even
though
inorganic
mercury
is
converted
to
methylmercury
and
methylmercury
bioaccumulates
to
a
great
extent,
this
criterion
does
not
account
for
uptake
via
the
food
chain
because
sufficient
data
were
not
available
when
the
criterion
was
derived.

ee
This
criterion
is
a
noncarcinogen.
As
prescribed
in
Section
E
of
this
regulation,
application
of
this
criterion
for
determining
permit
effluent
limitations
requires
the
use
of
7Q10
or
comparable
tidal
condition
as
determined
by
the
Department.

ff
EPA
is
currently
reassessing
the
criteria
for
arsenic.

gg
This
criterion
applies
to
DDT
and
its
metabolites
(
i.
e.,
the
total
concentration
of
DDT
and
its
metabolites
should
not
exceed
this
value).

hh
Although
a
new
RfD
is
available
in
IRIS,
the
surface
water
criteria
will
not
be
revised
until
the
National
Primary
Drinking
Water
Regulations:
Stage
2
Disinfectants
and
Disinfection
Byproducts
Rule
(
Stage
2
DBPR)
is
completed,
since
public
comment
on
the
relative
source
contribution
(
RSC)
for
chloroform
is
anticipated.

ii
Although
EPA
has
not
published
a
completed
criteria
document
for
phthalate,
it
is
EPA's
understanding
that
sufficient
data
exist
to
allow
calculation
of
aquatic
life
criteria.

A
This
human
health
criterion
is
the
same
as
originally
published
in
the
Red
Book
which
predates
the
1980
methodology
and
did
not
utilize
the
fish
ingestion
BCF
approach.
This
same
criterion
value
is
now
published
in
the
Gold
Book.

B
The
organoleptic
effect
criterion
is
more
stringent
than
the
value
presented
in
the
nonpriority
pollutants
table.

C
According
to
the
procedures
described
in
the
Guidelines
for
Deriving
Numerical
National
Water
Quality
Criteria
for
the
Protection
of
Aquatic
Organisms
and
Their
Uses,
except
possibly
where
a
very
sensitive
species
is
important
at
a

freshwater
aquatic

should
be
protected
if
both

are
satisfied.

D
This
criterion
has
been
revised
to
reflect
The

q1*
or
RfD,
as
contained
in
the
Integrated
Risk

as
of
April
8,
1998.
The
fish
tissue
bioconcentration
factor
(
BCF)
used
to
derive
the
original

was
retained
in
each

WATER
QUALITY
CRITERIA
ADDITIONAL
NOTES
1.
Criteria
Maximum
Concentration
and
Criterion
Continuous
Concentration
The
Criteria
Maximum
Concentration
(
CMC)
is
an
estimate
of
the
highest
concentration
of
a
material
in
surface
water
to
which
an
aquatic
community
can
be
exposed
briefly
without
resulting
in
an
unacceptable
effect.
The
Criterion
Continuous
Concentration
(
CCC)
is
an
estimate
of
the
highest
concentration
of
a
material
in
surface
water
to
which
an
aquatic
community
can
be
exposed
indefinitely
without
resulting
in
an
unacceptable
effect.
The
CMC
and
CCC
are
just
two
of
the
six
parts
of
a
aquatic
life
criterion;
the
other
four
parts
are
the
acute
averaging
period,
chronic
averaging
period,
acute
frequency
of
allowed
exceedence,
and
chronic
frequency
of
allowed
exceedence.

Criteria
for
Priority
Pollutants,
Non
Priority
Pollutants
and
Organoleptic

This
appendix
lists
all
priority
toxic
pollutants
and
some
nonpriority
toxic
pollutants,
and
both
human
health
effect
and
organoleptic
effect
criteria
issued
pursuant
to
CWA
§
304(
a),
the
SDWA,
and
the
NPDWR.
Blank
spaces
indicate
that
EPA
has
no
CWA
§
304(
a)
criteria
recommendations.
Because
of
variations
in
chemical
nomenclature
systems,
this
listing
of
toxic
pollutants
does
not
duplicate
the
listing
in
Appendix
A
of
40CFR
Part
423.

3.
Human
Health
Risk
The
human
health
criteria
for
the
priority
and
nonpriority
pollutants
are
based
on
carcinogenicity
of
10­
6
risk.

4.
Water
Quality
Criteria
published
pursuant
to
Section
304(
a)
or
Section
303(
c)
of
the
CWA
Many
of
the
values
in
the
appendix
were
published
in
the
California
Toxics
Rule.
Although
such
values
were
published
pursuant
to
Section
303(
c)
of
the
CWA,
they
represent
the
EPA's
most
recent
calculation
of
water
quality
criteria.

5.
Calculation
of
Dissolved
Metals
Criteria
The
304(
a)
criteria
for
metals
are
shown
as
total
recoverable
metals.
As
allowed
in
Section
E
of
this
regulation,
these
criteria
may
be
expressed
as
dissolved
metals.
Dissolved
metals
criteria
may
be
calculated
in
one
of
two
ways
(
please
refer
to
Attachments).
For
freshwater
metals
criteria
that
are
hardness­
dependent,
the
dissolved
metal
criteria
may
be
calculated
using
a
hardness
of
25
mg/
l
as
expressed
as
CaCO3.
Saltwater
and
freshwater
metals'
criteria
that
are
not
hardness­
dependent
are
calculated
by
multiplying
the
total
recoverable
criteria
before
rounding
by
the
appropriate
conversion
factors.
The
final
metals'
criteria
in
the
table
are
rounded
to
two
significant
figures.
Information
regarding
the
calculation
of
hardness
dependent
conversion
factors
are
included
in
the
footnotes.

and
source
refers
to
the
origin
of
the
value.
Many
of
the
numeric
values
contained
in
this
appendix
have
been
modified,
revised,
or
altered
and
therefore,
the
source
as
listed
may
not
be
the
same
as
it
appears
in
this
table.
Also,
South
Carolina
may
have
selected
to
use
a
different
value
or
may
have
promulgated
a
different
value
in
its
previous
iterations
of
this
regulation,
so
differences
from
these
sources
should
be
expected.

9.
Maximum
Contaminant
Levels
The
appendix
includes
Maximum
Contaminant
Levels
(
MCLs)
developed
under
the
Safe
Drinking
Water
Act
(
SDWA)
and
the
National
Primary
Drinking
Water
Regulation
(
NPDWR).

10.
Organoleptic
Effects
The
appendix
contains
304(
a)
criteria
for
pollutants
with
toxicity­
based
criteria
as
well
as
non­
toxicity
based
criteria.
The
basis
for
the
non­
toxicity
based
criteria
are
organoleptic
effects
(
e.
g.,
taste
and
odor)
which
would
make
water
and
edible
aquatic
life
unpalatable
but
not
toxic
to
humans.
The
table
includes
criteria
for
organoleptic
effects
for
23
pollutants.
Pollutants
with
organoleptic
effect
criteria
more
stringent
than
the
criteria
based
on
toxicity
(
e.
g.,
included
in
both
the
priority
and
non­
priority
pollutant
tables)
are
footnoted
as
such.

11.
Category
Criteria
In
the
1980
criteria
documents,
certain
water
quality
criteria
were
published
for
categories
of
pollutants
rather
than
for
individual
pollutants
within
that
category.
Subsequently,
in
a
series
of
separate
actions,
the
EPA
derived
criteria
for
specific
pollutants
within
a
category.
Therefore,
in
this
appendix
South
Carolina
is
replacing
criteria
representing
categories
with
individual
pollutant
criteria
(
e.
g.,
1,
3­
dichlorobenzene,
1,
4­
dichlorobenzene
and
1,
2­
dichlorobenzene).

12.
Specific
Chemical
Calculations
A.
Selenium
(
1)
Human
Health
In
the
1980
Selenium
document,
a
criterion
for
the
protection
of
human
health
from
consumption
of
water
and
organisms
was
calculated
based
on
a
BCF
of
6.0
l/
kg
and
a
maximum
waterrelated
contribution
of
35

g
Se/
day.
Subsequently,
the
EPA
Office
of
Health
and
Environmental
Assessment
issued
an
errata
notice
(
February
23,
1982),
revising
the
BCF
for
selenium
to
4.8
L/
kg.
In
1988,
EPA
issued
an
addendum
(
ECAO­
CIN­
668)
revising
the
human
health
criteria
for
selenium.
Later
in
the
final
National
Toxic
Rule
(
NTR,
57
FR
60848),
EPA
withdrew
previously
published
selenium
human
health
criteria,
pending
EPA
review
of
new
epidemiological
data.

This
appendix
includes
human
health
criteria
for
selenium,
calculated
using
a
BCF
of
4.8
L/
kg
along
with
the
current
IRIS
RfD
of
0.005
mg/
kg/
day.
South
Carolina
included
these
water
quality
criteria
in
the
appendix
because
the
data
necessary
for
calculating
a
criteria
in
accordance
with
EPA's
1980
human
health
methodology
are
available.

(
2)
Aquatic
Life
This
appendix
contains
aquatic
life
criteria
for
selenium
that
are
the
same
as
those
published
in
the
CTR.
In
the
CTR,
EPA
proposed
an
acute
criterion
for
selenium
based
on
the
criterion
proposed
for
selenium
in
the
Water
Quality
Guidance
for
the
Great
Lakes
System
(
61FR584440.
The
GLI
and
CTR
proposals
take
into
account
data
showing
that
selenium's
two
prevalent
oxidation
state
in
water,
selenite
and
selenate,
present
differing
potentials
for
aquatic
toxicity,
as
well
as
new
data
indication
that
various
forms
of
selenium
are
additive.
The
new
approach
produces
a
different
selenium
acute
criterion
concentration,
or
CMC,
depending
upon
the
relative
proportions
of
selenite,
selenate,
and
other
forms
of
selenium
that
are
present.
EPA
is
currently
undertaking
a
reassessment
of
selenium,
and
expects
the
304(
a)
criterion
for
selenium
will
be
revised
based
on
the
final
reassessment
(
63FR26186).
However,
until
such
time
as
revised
water
quality
criteria
for
selenium
are
published
by
the
EPA,
the
water
quality
criteria
in
this
appendix
are
EPA's
current
304(
a)
criteria.

B.
Chromium
(
III)

The
aquatic
life
water
quality
criteria
for
chromium
(
III)
included
in
the
appendix
are
based
on
the
values
presented
in
the
document
titled:
1995
Updates:
Water
Quality
Criteria
Documents
for
the
Protection
of
Aquatic
Life
in
Ambient
Water.

C.
PCBs
In
this
appendix,
South
Carolina
is
publishing
aquatic
life
and
human
health
criteria
based
on
total
PCBs
rather
than
individual
arochlors.

Water
Act
(
CWA).

Legal
Authority:
S.
C.
Code
Sections
48­
1­
40,
48­
1­
60,
and
48­
1­
80,
implementing
the
CWA.
Plan
for
Implementation:
The
proposed
amendment
would
be
incorporated
within
R.
61­
68
upon
approval
of
the
General
Assembly
and
publication
in
the
State
Register.
The
proposed
amendment
will
be
implemented
in
the
same
manner
in
which
the
present
regulation
is
implemented.

DETERMINATION
OF
NEED
AND
REASONABLENESS
OF
THE
PROPOSED
REGULATION
BASED
ON
ALL
FACTORS
HEREIN
AND
EXPECTED
BENEFIT:
This
amendment
is
required
to
comply
with
Federal
requirements
of
Section
303(
c)(
2)(
B)
of
the
CWA.

­
The
adoption
of
federal
toxics
criteria
to
reflect
the
most
current
final
published
criteria
according
to
Sections
304(
a)
and
307(
a)
of
the
CWA.

The
proposed
changes
to
R.
61­
68
relating
to
human
health
and
aquatic
life
criteria
are
reasonable
because
the
stated
criteria
in
the
amendment
are
based
on
sound
scientific
principles
and
are
required
in
order
to
comply
with
the
goals
of
Section
101(
a)(
2)
and
303(
c)
of
the
CWA
for
protection
and
maintenance
of
the
uses
of
the
waters
of
the
State.
These
changes
include
using
a
larger
fish
tissue
consumption
rate
that
better
reflects
true
consumption
patterns
and
provides
a
more
protective
risk
level
for
bioaccumulative
pollutants.

­
Review
and
revision
of
the
bacterial
indicator
for
protection
of
recreational
uses.

The
proposed
changes
reflect
EPA=
s
requirement
under
the
CWA
amendments,
also
known
as
the
Beaches
Environmental
Assessment
and
Coastal
Health
Act
(
BEACH
Act
amendments)
that
South
Carolina
adopt
either
E.
coli
or
enterococci
as
its
bacterial
indicator
organism
for
its
coastal
recreational
waters
by
April
of
2004.
The
Department
is
proposing
the
use
of
enterococci
for
all
of
its
saltwaters
in
order
to
comply
with
EPA's
requirements.

­
Inclusion
of
an
allowance
for
a
variance
from
water
quality
standards.

South
Carolina's
current
water
quality
standards
do
not
include
a
provision
for
a
variance
from
those
standards.
The
Department
has
recently
reviewed
the
applicability
of
variances
where
under
certain
situations
the
use
attainment
may
not
be
currently
achieved
but
may
be
achieved
at
a
future
date.
The
Department
believes
that
a
variance
provision
would
be
a
beneficial
and
necessary
inclusion
for
our
state's
water
quality
standards.
We
have
included
language
that
specifies
when
and
how
a
variance
may
be
granted
by
the
Department.

­
Stylistic
changes
which
may
include
corrections
for:
readability,
grammar,
punctuation,
typography,
codification,
references,
and
language
style.

DETERMINATION
OF
COSTS
AND
BENEFITS:
Existing
staff
and
resources
will
be
utilized
to
implement
this
amendment
to
the
regulation.
No
additional
cost
will
be
incurred
by
the
State
if
the
revisions
are
implemented
and
therefore,
no
additional
State
funding
is
being
requested.

In
reviewing
the
potential
for
significant
economic
impact
of
the
proposed
amendment,
the
Department
specifically
evaluated
situations
in
which
costs
would
most
likely
be
incurred
by
the
regulated
community.
These
estimates
addressed
the
specific
revisions
by
issue
after
determining
those
of
greatest
potential
impact.
The
Department
found
that
the
overall
impact
to
the
State=
s
political
subdivisions
or
the
regulated
community
as
a
whole
was
not
likely
to
be
significant
in
that
the
existing
narrative
standards
would
have
incurred
similar
cost
or
the
fact
that
the
design
standards
required
under
the
amendment
will
be
substantially
consistent
with
the
current
guidelines
and
review
guidelines
utilized
by
the
Department.
Further,
much
of
the
proposed
amendment,
for
which
an
estimated
cost
may
be
incurred
by
the
regulated
community
at
the
time
of
permit
issuance,
are
essential
and
necessary
to
protect
and
maintain
the
existing
uses
supported
by
the
water
quality
standards
and
are,
therefore,
beyond
the
scope
of
cost
analysis
in
that
they
provide
the
minimum
level
of
protection
for
aquatic
life
and
human
health
as
required
by
the
CWA.

UNCERTAINTIES
OF
ESTIMATES:
Minimal
to
moderate.

EFFECT
ON
ENVIRONMENT
AND
PUBLIC
HEALTH:
Implementation
of
this
amendment
will
not
compromise
the
protection
of
the
environment
or
the
health
and
safety
of
the
citizenry
of
the
State.
The
amendment
will
promote
and
protect
aquatic
life
and
human
health
by
the
regulation
of
pollutants
into
waters
of
the
State.

DETRIMENTAL
EFFECT
ON
THE
ENVIRONMENT
AND
PUBLIC
HEALTH
IF
THE
REGULATION
IS
NOT
IMPLEMENTED:
Failure
by
the
Department
to
incorporate
appropriately
protective
water
quality
standards
in
the
regulation
that
are
the
basis
for
issuance
of
National
Pollutant
Discharge
Elimination
System
(
NPDES)
permits,
stormwater
permits,
wasteload
and
load
allocations,
groundwater
remediation
plans,
and
multiple
other
program
areas
will
lead
to
contamination
of
the
waters
of
the
State
with
detrimental
effects
on
the
health
of
flora
and
fauna
in
the
State
as
well
as
the
citizens
of
South
Carolina.

Statement
of
Rationale:

The
statement
of
rationale
was
determined
by
staff
analysis
pursuant
to
S.
C.
Code
Section
1­
23­
110(
A)(
3)(
h).

The
first
two
issues
contained
in
the
proposed
amendment
of
R.
61­
68
are
requirements
of
the
CWA
and
are
necessary
for
compliance
with
EPA's
recommendations
for
the
triennial
review
of
the
water
quality
standards
to
ensure
consistency
with
the
CWA.
The
two
remaining
issues
are
Department
initiated
and
are
necessary
and
essential
to
the
water
quality
standards
program
in
South
Carolina
and
to
the
quality
of
the
regulation
itself.
The
water
quality
standards
variance
provision
will
ensure
that
water
quality
use
standards
may
be
maintained
while
providing
for
reasonable
expectations
for
dischargers
when
all
applicable
classified
uses
cannot
be
attained
at
this
time
to
the
level
of
achieving
a
numeric
criteria
set
for
that
classified
use.
This
will
ensure
a
reasonable
expectation
of
eventual
achievement
of
the
use
and
that
meaningful
progress
towards
that
achievement
will
be
reevaluated
at
least
every
three
years
at
the
time
of
the
triennial
review
of
the
water
quality
standards
in
compliance
with
Section
303(
c)(
2)(
B)
of
the
CWA.
The
remaining
issue
is
one
of
revisions
based
entirely
on
corrections
or
clarity
of
the
language
in
the
regulation
in
order
to
maintain
a
regulation
that
is
efficient,
readable,
and
accurate.
