assessment,
for
the
cumulative
assessment
the
risks
from
all
sources
are
summed
and
compared
to
a
cumulative
significance
threshold.
A
summary
of
the
cumulative
existing
plus
project
health
impacts
is
presented
in
Draft
EIR
Table
6-3
(page
6-20)
,
which
includes
stationary
sources,
local
roadway
sources
and
Caltrain
operations.
It
should
be
noted
that
US
Highway
101
would
be
over
1,000
feet
from
the
nearest
proposed
sensitive
receptor
for
the
DSP
and
DSP-V
scenarios
and,
based
on
BAAQMD
guidance,
is
sufficiently
distant
from
the
highway
as
to
not
warrant
inclusion
in
the
health
risk
assessment.
As
demonstrated
in
Table
6-3,
health
impacts
from
Project
Site
development
plus
other
existing
sources
(permitted
sources
and
roadways)
in
the
area
would
have
a
cumulative
impact
below
the
BAAQMD
threshold
of
100
per
million
and
would
be
less
than
significant.
The
Draft
EIR
focuses
on
changes
to
the
environment
that
would
result
from
proposed
Baylands
development,
analyzes
the
significance
of
those
changes,
and
proposes
mitigation
measures
for
impacts
that
are
determined
to
be
significant.
Liquefaction
resulting
from
an
earthquake
would
result
in
loss
of
soils
stability,
but
would
not
create
measureable
emissions
of
TAC
that
would
be
an
impact
of
proposed
Baylands
development.
The
determination
of
significance
in
Impact
4.B-6
of
the
Draft
EIR
is
made
using
BAAQMD
recommended
methodologies
(BAAQMD,
2012)
and
input
data.
Risk
estimates
provided
as
inputs
are
either
from
formal
facility-specific
health
risk
assessments
or
are
BAAQMD
estimates
at
the
property
line
of
the
facility
and
are
based
on
maximum
permitted
emission
levels,
resulting
in
a
conservative
analysis.
Because
impacts
were
determined
to
be
less
than
significant,
no
mitigation
is
required.
The
risk
values
presented
in
Table
4.B-20
for
the
Kinder
Morgan
facility
and
other
stationary
sources
reflect
the
distance
to
the
nearest
sensitive
receptor.
The
BAAQMD-reported
property
line
cancer
risk
for
the
Kinder
Morgan
facility
is
26.4
excess
cancer
cases
per
million,
while
the
BAAQMD-reported
property
line
cancer
risk
for
the
Bayshore
Chevron
Station
is
13.4
excess
cancer
cases
per
million.
Therefore,
the
at-
property
line
risk
from
the
Kinder
Morgan
facility
is
greater
than
this
gasoline
station.
However,
the
distance
of
the
Kinder
Morgan
facility
from
the
nearest
proposed
sensitive
receptor
(approximately
1,300
feet)
results
in
a
lower
risk
than
from
the
service
stations
which
are
significantly
closer
to
sensitive
receptors
(approximately
200
feet).
