Because
methane
rises
toward
the
surface
as
it
moves
away
from
its
source,
Mitigation
Measure
4.G-2h
requires
vapor
intrusion
systems
at
a
greater
distance
(1,000
feet)
to
protect
buildings
with
concrete
slabs
at
the
ground
surface
than
is
required
to
protect
subsurface
vaults
and
other
subsurface
features
(500
feet).
It
is
presumed
that
this
comment
refers
to
implementation
of
a
centralized
monitoring
and
recording
system
required
by
Mitigation
Measure
4.G-2h.
See
Chapter
4.0,
Mitigation
Monitoring
and
Reporting
Program
,
of
the
Final
EIR
for
information
regarding
requirements
for
worker
training
related
to
that
mitigation
measure.
“Icehouse
District”
is
a
term
used
in
the
proposed
Brisbane
Baylands
Specific
Plan
prepared
by
the
applicant
for
the
DSP
and
DSP-V
scenarios.
It
refers
to
the
area
encompassing
and
north
of
Icehouse
Hill,
west
of
the
Caltrain
track,
as
shown
in
Draft
EIR
Figure
See
for
discussion
of
the
adequacy
of
existing
studies
for
use
in
the
Draft
EIR
and

for
discussion
of
compliance
with
the
law
as
mitigation
under
CEQA.
The
text
referenced
in
this
comment
is
Impact
Statement
4.G-3,
which
is
taken
directly
from
CEQA
Guidelines
Appendix
G.
The
environmental
analysis
related
to
this
impact
statement
is
intended
to
address
whether
a
proposed
project
would
emit
hazardous
emissions
or
handle
acutely
hazardous
materials,
substances,
or
wastes
within
¼
mile
of
an
existing
or
proposed
school.
As
discussed
in
the
Draft
EIR
project
description,
the
proposed
uses
for
each
of
the
four
development
scenarios
do
not
propose
such
uses
within
¼
mile
of
an
existing
or
proposed
school.
All
proposed
uses
within
the
Baylands
must
be
consiste
nt
with
the
City’s
General
Plan,
which
currently
restricts
such
uses.
In
addition,
since
Mitigation
Measure
4.G-2e
requires
Hazardous
Materials
Business
Plans
to
be
prepared
and
school
siting
to
meet
applicable
state
requirements,
the
Draft
EIR
determined
that
proposed
Baylands
development
would
have
a
less
than
significant
impact
in
relation
to
Impact
4.G-3.
See
also
for
discussion
regarding
the
siting
of
school
within
¼
mile
of
the
Kinder
Morgan
tank
farm.
The
conclusions
on
Page
4.G-101
are
revised
to
read
as
follows:
Conclusion:
This
impact
would
be
significant,
and
implementation
of
Mitigation
Measures
4.G-12a
and
4.G-12b
is
recommended
under
all
four
proposed
development
scenarios.
Conclusion
with
Mitigation
:
With
the
inclusion
of
Mitigation
Measures
4.G-12a
and
4.G-12b
,
impacts
related
to
being
located
on
