Regarding
the
MP&

Rule
This
Memorandum
is
in
response
to
your
Technical
Directive
of
December

under
Work
Assignment:

where
you
requested
ERG
to
perform
several
tasks
in
regard
to
the
MP&
M
rule.
Each
task
of
your
Technical
Directive
is
discussed
separately
below.

Tasks
1
&
2.
Read
the
highlighted
portions
of
the
comments
attached
to
Elenda
Besedin's
email,
and
check
the
bioconcentration
factor
for
lead
in
fish
tissue
Versar
recommends
the
following
responses
to
the
commenter's
concerns:

Comment
1:
"
EPA
used
a
bioconcentration
factor
of
49
L/
kg
for
estimating
lead
concentrations
in
fish,
but
other
recent
EPA
documents
proposed
a
bioconcentration
for
lead
in
fish
tissue
of
0.09
L/
kg,
a
differential
factor
of
more
than
500."

Response:

EPA
believes
the
use
of
a
BCF
value
of
49
L/
kg
for
lead
in
fish
tissue
is
justified.
This
value,
which
indicates
that
lead
has
a
slight
potential
to
bioaccumulate,
is
based
on
the
"
weighted
average
BCF
for
lead
and
the
edible
portion
of
all
freshwater
and
estuarine
aquatic
organisms
consumed
by
Americans"
as
reported
in
the
1980
ambient
water
quality
criteria
document
for
lead
(
EPA
440/
5­
80­
057).
This
value
is
also
currently
reported
in
the
1996
Superfund
Chemical
Data
Matrix
(
EPA
540/
R­
96/
028).
The
median
BCF
value
of
42
for
fish,
presented
in
ATSDR's
Toxicological
Profile
for
Lead
is
very
similar.
Typically,
a
conservative
value
(
i.
e.,
the
highest
BCF)
among
comparable
candidate
values
is
selected
for
human
health
effect
estimations.
In
the
case
of
lead,
the
value
of
49
L/
kg
was
selected
by
EPA.
EPA
considers
its
selection
to
be
consistent
with
the
BCF
value
and
guidelines
used
in
numerous
past
rule
makings.

Comment
2:
"
For
the
31
pollutants
projected
to
exceed
aquatic
life­
based
AWQC,
numerical
water
quality
criteria
are
available
for
only
14.
EPA
has,
therefore,
imputed
water
quality
criteria
from
some
unknown
source
and
both
their
applicability
and
validity
are
suspect
until
substantial
scientific
and
peerreviewed
data
are
provided
in
the
record.
Nearly
56
percent
of
the
baseline
exposures
in
EPA's
assessment
are
attributable
to
pollutants
for
which
no
AWQC
exist."

Response:

As
acknowledged
by
the
commentor,
ideally,
EPA
would
have
developed
a
full
suite
of
ambient
freshwater
and
saltwater
quality
criteria
for
the
protection
of
aquatic
life
and
human
health
for
all
2
pollutants
considered
in
the
environmental
benefits
assessment.
However,
EPA
has
not
been
able
to
develop
this
suite
of
criteria
and
thus,
must
estimate
"
criteria
values"
using
available
data
within
the
context
of
a
scientifically
defensible
methodology
for
prioritizing
and
selecting
values
most
representative
of
a
chemical's
toxicity.
The
methodology
developed
by
EPA
for
selecting
these
values
is
explained
in
Attachment
1]
References
and
codes
for
the
values
used
for
the
pollutants
of
concern
are
also
provided
(
See
Attachments
2
and
3).
The
record
has
been
updated
accordingly.

Comment
3:
"
EPA
included
two
chemicals
in
the
projected
exceedances
for
human
health­
based
AWQC
for
which
there
are
no
AWQC,
p­
cresol
and
pyridine.
EEBA,
Table
E.
8.
Theses
chemicals
account
for
18
of
11,343
exceedances
at
baseline
conditions,
resulting
in
a
modest
overestimate
of
projected
exceedances."

Response:

See
response
to
Comment
2.

Comment
4:
"
In
its
environmental
benefits
analysis,
EPA
projected
substantial
reductions
in
water
quality
exceedances
associated
with
manganese
and
iron.
The
naturally
occurring
concentrations
of
these
two
constituents
are
often
above
the
water
quality
criteria
concentrations.
Furthermore,
the
projected
reduction
in
water
quality
exceedances
associated
with
consumption
of
organisms
is
attributable
to
only
two
compounds
­
arsenic
and
manganese.
Such
exceedances
attributable
solely
to
manganese
comprise
about
51
percent
of
this
total.
Accordingly,
it
is
inappropriate
to
include
manganese
and
iron
in
the
evaluation
of
benefitting
reaches,
unless
background
levels
of
these
elements
are
taken
into
consideration."

Response:

EPA
does
not
agree
with
the
commentor's
contention
that
manganese
and
iron
should
not
be
considered
pollutants
of
concern
because
they
are
common
components
of
natural
waters.
EPA
acknowledges
that
both
manganese
and
iron
may
be
present
at
concentrations
that
may
be
greater
than
the
water
quality
criteria
concentrations.
However,
the
environmental
assessment
assumes
that
the
background
concentrations
of
each
pollutant,
both
in
the
receiving
stream
and
in
the
POTW
influent
are
equal
to
zero;
therefore,
the
analysis
evaluates
only
the
impacts
of
discharging
facilities.
This
is
consistent
with
the
assessments
conducted
for
other
rule
makings.
In
addition,
the
toxicological
data
for
these
compounds
indicate
that
above
certain
concentrations,
impacts
may
occur.

Comment
5:
"
Of
the
31
chemicals
presented
in
Table
X­
1,
numerical
AWQC
are
actually
available
for
only
14.
EPA
has
not
provided
the
proper
information
in
the
record
showing
and
justifying
the
values
used
for
AWQC
for
these
constituents.
Until
such
justification
is
provided,
exceedances
attributed
to
these
constituents
are
not
valid.
For
the
constituents
in
question,
removal
of
acute
and
chronic
exceedances
due
to
unjustified
AWQC
represents
a
decrease
in
baseline
exceedances
of
8
percent
and
39
percent,
respectively."

Response:
1Note
that
the
technical
directive
cites
incorrect
table
references.
The
aquatic
life
values
in
Appendix
E
are
in
Table
E.
3,
not
E.
10.
Also,
Table
13.3
appears
to
only
include
POCs
for
which
human
health
values
have
been
used.
The
complete
list
of
all
POCs
is
in
Table
E.
2.
In
addition,
phosphate
(
but
not
elemental
phosphorus)
is
on
the
list
of
aquatic
life
and
human
values
in
Appendix
E,
Tables
E.
3
and
E.
2;
conversely,
elemental
phosphorus
(
but
not
phosphate)
is
on
the
list
of
human
health
values
in
Table
13.3.
We
have
included
phosphate
on
our
tables
in
Attachment
2
based
on
your
directions.
Diethyl
ether
has
not
been
included
even
though
it
appears
on
Table
13.3,
but
not
on
Tables
E.
2
or
E.
3
(
which
state
132
POCs
in
the
title,
but
include
only
131
POCs).
This
was
also
based
on
your
direction.

Comment
6:
These
sulfide
exceedances
comprise
25
percent
of
all
projected
chronic
aquatic
life
exceedances.
In
addition,
sulfide
comprises
17
percent
of
the
projected
reductions
in
exceedances
based
on
the
proposed
option.
However,
sulfide
is
a
very
volatile
constituent,
and
is
likely
transient
and
shortlived
once
it
enters
a
receiving
stream.
It
is
likely
that
any
benefits
attributable
to
sulfide
are
overestimated."

Response:

Hydrogen
sulfide
is
a
soluble,
highly
poisonous,
gaseous
compound
having
the
characteristic
odor
of
rotten
eggs.
It
will
dissolve
in
water
at
4,000
mg/
L
at
20
°
C
and
1
atmosphere
of
pressure.
When
soluble
sulfides
are
added
to
water,
they
react
with
hydrogen
ions
to
form
HS!
or
H2S,
the
proportion
of
each
depending
on
the
pH.
The
degree
of
hazard
exhibited
by
sulfide
to
aquatic
animal
life
is
dependent
on
the
temperature,
pH,
and
dissolved
oxygen.
At
lower
pH
values
a
greater
proportion
is
in
the
form
of
the
toxic
undissociated
H2S.
Long­
term
data,
both
in
field
situations
and
under
controlled
conditions,
demonstrate
hydrogen
sulfide
toxicity
at
low
concentrations.
EPA
has
established
AWQC
at
2
µ
g/
L
(
chronic
aquatic
life).

EPA
also
recognizes
that
the
hazard
from
hydrogen
sulfide
to
aquatic
life
is
often
localized
and
transient.
However,
the
environmental
assessment
is
designed
to
evaluate
aquatic
life
impacts
at
the
point
of
discharge,
not
considering
pollutant
fate
processes,
using
estimated
concentrations
that
are
environmentally
conservative.
These
assumptions
are
consistent
with
other
rulemakings.

Task

Water
Quality
Criteria
The
analysis
obtains
the
AWQC
(
or
toxic
effect
levels)
for
the
protection
of
aquatic
life
and
human
health
from
a
variety
of
sources,
including
EPA
criteria
documents,
EPA's
ASTER,
and
EPA's
IRIS.
It
uses
ecological
toxicity
estimations
when
published
values
are
not
available.
The
hierarchies
used
to
select
the
appropriate
aquatic
life
and
human
health
values
are
described
in
the
following
sections.

(
a)
Aquatic
Life
EPA
establishes
AWQC
for
many
pollutants
for
the
protection
of
freshwater
aquatic
life
(
acute
and
chronic
criteria).
The
acute
value
represents
a
maximum
allowable
1­
hour
average
concentration
of
a
pollutant
at
any
time
and
can
be
related
to
acute
toxic
effects
on
aquatic
life.
The
chronic
value
represents
the
average
allowable
concentration
of
a
toxic
pollutant
over
a
4­
day
period
at
which
a
diverse
genera
of
aquatic
organisms
and
their
uses
should
not
be
unacceptably
affected,
provided
that
these
levels
are
not
exceeded
more
than
once
every
3
years.

For
pollutants
for
which
no
AWQC
are
developed,
the
analysis
uses
specific
toxicity
values
(
acute
and
chronic
effect
concentrations
reported
in
published
literature
or
estimated
using
various
application
techniques).
When
selecting
values
from
the
literature,
the
analysis
prefers
measured
concentrations
from
flow­
through
studies
under
typical
pH
and
temperature
conditions.
The
test
organism
has
to
be
a
North
American
resident
species
of
fish
or
invertebrate.
The
hierarchies
used
to
select
the
appropriate
acute
and
chronic
values
are
listed
below
in
descending
order
of
priority.

Acute

The
analysis
derives
the
values
for
ingesting
water
and
organisms
by
assuming
an
average
daily
ingestion
rate
of
2
liters
of
water,
an
average
daily
fish
consumption
rate
of
6.5
grams
of
potentially
contaminated
fish
products,
and
an
average
adult
body
weight
of
70
kilograms
(
U.
S.
EPA,
1991).
If
EPA
has
established
a
slope
factor,
the
analysis
uses
values
protective
of
carcinogenicity
to
assess
the
potential
effects
on
human
health.

The
analysis
develops
protective
concentration
levels
for
carcinogens
in
terms
of
nonthreshold
lifetime
risk
level,
using
criteria
at
a
risk
level
of
10­
6
(
1E­
6).
This
risk
level
indicates
a
probability
of
1
additional
case
of
cancer
for
every
1
million
persons
exposed.
Toxic
effects
criteria
for
noncarcinogens
include
systemic
effects
(
e.
g.,
reproductive,
immunological,
neurological,
circulatory,
or
respiratory
toxicity),
organ­
specific
toxicity,
developmental
toxicity,
mutagenesis,
and
lethality.

The
hierarchy
used
to
select
the
most
appropriate
human
health
criteria
values
is
listed
below
in
descending
order
of
priority:

1.
Human
health
criteria
values
calculated
using
EPA's
IRIS
RfDs
or
SFs
in
conjunction
with
adjusted
3
percent
lipid
BCF
values
derived
from
Quality
Criteria
for
Water
(
U.
S.
EPA,
1980).
Three
percent
is
the
mean
lipid
content
of
fish
tissue
reported
in
the
study
from
which
the
average
daily
fish
consumption
rate
of
6.5
g/
day
is
derived.

2.
Human
health
criteria
values
calculated
using
current
IRIS
RfDs
or
SFs
and
representative
BCF
values
for
common
North
American
species
of
fish
or
invertebrates
or
estimated
BCF
values.

3.
Human
health
criteria
values
calculated
using
RfDs
or
SFs
from
EPA's
HEAST
or
EPA's
Region
III

in
conjunction
with
adjusted
3
percent
lipid
BCF
values
derived
from
Quality
Criteria
for
Water
(
U.
S.
EPA,
1980).

4.
Human

or

or

Region
III
RBC
Table
and
representative
BCF
values
for
common
North
American
species
of
fish
or
invertebrates
or
estimated
BCF
values.

5.
Criteria
from
the
Quality
Criteria
for
Water
(
U.
S.
EPA,
1980).

6.
Human
health
values
calculated
using
RfDs
or
SFs
from
data
sources
other
than
IRIS,
HEAST,
or
Region
III
RBC
Table.

This
hierarchy
is
based
on
Section
2.4.6
of
the
Technical
Support
Document
for
Water
Qualitybased
Toxics
Control
(
U.
S.
EPA,
1991),
which
recommends
using
the
most
current
risk
information
from
A1­
6
IRIS
when
estimating
human
health
risks.
In
cases
where
chemicals
have
both
RfDs
and
SFs
from
the
same
level
of
the
hierarchy,
the
analysis
calculates
human
health
values
using
the
formulas
for
carcinogenicity,
which
always
result
in
the
more
stringent
value,
given
the
risk
levels
employed.

Physical­
Chemical
Property
Data
The
analysis
uses
3
measures
of
physical­
chemical
properties
to
evaluate
environmental
fate:

Henry's
Law
constant
(
HLC),
organic­
carbon
adsorption
partition
coefficient
(
Koc)
and
biodegradation
half­
life
(
BD).

HLC
is
the
ratio
of
vapor
pressure
to
solubility
and
is
indicative
of
the
propensity
of
a
chemical
to
volatilize
from
surface
water
(
Lyman
et
al.,
1982).
The
larger
the
HLC,
the
more
likely
that
the
chemical
will
volatilize.
The
analysis
obtains
most
HLCs
from
EPA's
Office
of
Pesticides
and
Toxic
Substances'

(
OPTS)
1989
Toxic
Chemical
Release
Inventory
Risk
Screening
Guide
(
U.
S.
EPA,
1989),
and
Syracuse
Research
Corporation's
CHEMFATE
database.

Koc
is
indicative
of
the
propensity
of
an
organic
compound
to
adsorb
to
soil
or
sediment
particles
and,
therefore,
to
partition
to
such
media.
The
larger
the
Koc,
the
more
likely
that
the
chemical
will
adsorb
to
solid
material.
The
analysis
obtains
most
Kocs
from
Syracuse
Research
Corporation's
CHEMFATE
database.

The
biodegradation
half­
life
(
BD)
is
the
empirically
derived
length
of
time
during
which
half
the
amount
of
a
chemical
in
water
is
degraded
by
microbial
action
in
the
presence
of
oxygen.
BD
is
indicative
of
the
environmental
persistence
of
a
chemical
released
into
the
water
column.
The
analysis
obtains
most
BDs
from
the
Handbook
of
Environmental
Degradation
Rates
(
Howard,
1991).
