See
for
discussion
regarding
the
remediation
review
and
approval
process.
The
Draft
EIR
is
correct
in
its
statement
that
regulatory
authority
for
remediation
and
Title
27
landfill
closure,
including
determination
and
approval
of
specific
remedial
technologies,
rests
with
the
RWQCB
and
DTSC.
The
City
of
Brisbane
has
regulatory
authority
over
land
uses
within
the
Baylands.
As
discussed
in
13,
human
health
risk
assessments
and
risk-based
cleanup
goals
will
be
established
by
the
RWQCB
and
DTSC
based
on
the
land
uses
determined
by
the
City
to
be
appropriate
within
the
Baylands.
See
13
for
discussion
of
the
of
the
remediation
review
process
for
the
Baylands
and
for
discussion
of
the
adequacy
of
existing
studies
for
use
in
the
Draft
EIR.
The
human
health
risk
assessments
to
be
undertaken
under
the
oversight
of
the
RWQCB
and
DTSC,
along
with
risk-based
cleanup
goals
and
determination
of
remediation
technologies
will
address
possible
exposure
pathways,
including
seepage
of
leachate
into
the
Brisbane
Lagoon
and
the
potential
for
encountering
pockets
of
toxic
gases.
Pursuant
to
the
provisions
of
CEQA,
the
Draft
EIR
analyzes
physical
changes
to
the
environment
that
would
result
from
the
proposed
Baylands
development,
which
is
set
forth
in
Chapter
3
of
the
Draft
EIR,
including
impacts
of
site
remediation
and
grading,
infrastructure
construction
and
operation,
provision
of
water
supply,
and
land
use
development
and
operations.
No
undercrossings
of
the
Caltrain
line
are
proposed
as
part
of
Baylands
development
and
no
proposals
for
rail
line
undercrossings
within
the
Baylands
are
known.
Any
proposals
to
lower
the
Caltrain
line
as
it
runs
through
the
Baylands
are
not
a
part
of
the
project
description
being
analyzed
in
the
Draft
EIR,
nor
have
any
such
proposals
by
others
been
identified
as
being
reasonably
foreseeable,
and
therefore
included
in
the
analysis
of
cumulative
impacts.
“Burying”
the
historic
roundhouse
would
result
in
a
sign
ificant
cultural
resources
impact,
and
is
not
included
as
part
of
proposed
Baylands
development.
As
stated
determinations
as
to
the
specific
technologies
to
be
employed
for
Title
27
landfill
closure
and
remediation
of
the
landfill
falls
under
the
regulatory
authority
of
the
RWQCB
and
DTSC,
and
will
require
site-
specific
environmental
evaluations
once
specific
remediation
technologies
are
selected.
See
1
for
discussion
regarding
environmental
review
of
site-specific
development
proposals,
including
site
remediation.
The
comment
provides
no
factual
basis
to
support
the
assertion
regarding
waste
layer
infiltration
through
various
pathways.
The
proposed
remedial
action
for
the
former
Brisbane
Landfill
will
be
required
to
address:
(1)
lack
of
a
low
permeability
engineered
landfill
cap
compliant
with
Title
27,
(2)
the
presence
of
leachate
and
the
requirement
to
Brisbane
Baylands
