Human
contact
with
the
surface
water
within
the
Lagoon
would
not
be
permitted
pursuant
to
the
Biological
Resources
mitigation
measures
set
forth
in
the
Draft
EIR.
Remedial
actions
required
for
the
former
Brisbane
Landfill,
and
must
be
completed
prior
to
development
of
those
portions
of
the
Project
site.
Currently
proposed
remedial
actions
within
the
Draft
EIR
are
described
on
pages
4.G-78
through
4.G-86.
Additionally,
the
proposed
remedial
actions
for
the
former
Brisbane
Landfill
must
be
in
compliance
with
Title
27
CCR
21190.
The
remedial
action
proposed
within
the
Draft
EIR
for
the
surface
water
management
system
as
part
of
the
remediation
of
the
Brisbane
Landfill
includes
restructuring
the
Central
Drainage
Channel
and
installing
a
layered
lined
system
that
includes
a
barrier
membrane
to
ensure
the
Central
Drainage
Channel
and
Brisbane
Lagoon
are
not
impacted
from
leachate
migration
from
the
landfill.
Remedial
actions
to
be
undertaken
within
the
Baylands,
including
Title
27
landfill
closure,
will
occur
pursuant
to
the
regulatory
authority
of
the
RWQCB,
DTSC,
and
the
San
Mateo
County
Health
system
(landfill
closure).
Remediation
of
and
will
be
required
to
meet
the
risk-based
cleanup
standards
set
by
the
RWQCB
and
DTSC
based
on
human
health
risk
assessments
recognizing
the
land
uses
determined
by
the
City
of
Brisbane
to
be
appropriate
within
the
Baylands.
These
human
health
risk
assessments
will
address
all
relevant
exposure
pathways.
The
remedial
technologies
ultimately
undertaken
within
the
Baylands
are
subject
to
review
and
approval
of
the
RWQCB
and
DTSC
as
discussed
13.
This
comment
notes
the
various
contaminants
illustrated
on
Figures
4.G-6a
through
4.G-6m,
and
does
not
raise
any
significant
environmental
issues
regarding
the
adequacy
of
these
graphics,
the
adequacy
of
the
Draft
EIR,
or
its
analyses
and
conclusions.
This
comment
sets
forth
information
from
the
Draft
EIR
and
the
February
2012
Geosyntec
report.
It
does
not
raise
any
significant
environmental
issues
regarding
the
adequacy
of
the
Draft
EIR
or
its
analyses
and
conclusions.
See
1
for
discussion
of
the
programmatic
nature
of
the
Draft
EIR,
for
discussion
regarding
the
review
and
approval
process
for
remediation
and
landfill
closure
plans,
and
for
discussion
of
the
adequacy
of
current
studies
for
use
in
the
Draft
EIR.
As
discussed
in
those
master
responses,
the
Draft
EIR
provides
a
programmatic
environmental
analysis
that
will
be
followed
by
site-specific
environmental
documentation,
addressing
the
specific
remediation
and
landfill
closure
technologies
to
be
implemented.
