prevent
any
increases
in
leachate

exceed
any
regulatory
thresholds,
(3)
hydrologic
connectivity
to
groundwater
and
surface
water,
primarily
the
Central
Drainage
Channel,
(4)
ongoing
consolidation
of

and
Bay

and
(5)

of

gas.
The
former
landfill
remediation
includes
both
Final
Closure
and
Post-Closure
Plans
to
be
ultimately
approved
by
the
regulatory
agencies,
and
in
compliance
with
Title
27
will
include:
(1)
operation
and
maintenance
of
a
leachate
seep
collection
and
transmission
system,
(2)
operation
and
maintenance
of
the
landfill
gas
collection
and
control
system,
(3)
continued
groundwater,
surface
water
and
leachate
quality
monitoring
and
evaluation,
(4)
installation
of
a
final
cover
system
over
the
entire
landfill,
and
(5)
operation
of
a
landfill
gas
collection
and
monitoring
system.
Additionally
proposed
development
will
be
subject
to
land
use
controls
such
as
deed
restrictions
and
require
notifications
for
any
disturbances
of
the
ground.
The
proposed
remedial
action
discussed
in
the
Draft
EIR
for
the
surface
water
management
system
as
part
of
the
remediation
of
the
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.
However,
that
proposed
action
is
subject
to
regulatory
agency
review
and
approval,
which
could
result
in
a
different
remedial
action
being
undertaken.
Regardless
of
the
ultimate
remedial
action
taken
by
the
applicable
regulatory
agency,
the
Draft
EIR
found
that
achievement
of
remediation
goals
(which
must
be
confirmed
prior
to
approval
of
a
specific
plan
for
any
parcel
within
the
Project
site),
compliance
with
federal,
state
and
local
regulations
pertaining
to
the
handling
and
disposal
of
hazardous
waste,
along
with
implementation
of
recommended
mitigation
measures,
would
reduce
hazardous
materials-related
impacts
to
less
than
significant.
The
comment
speculates
about
potential
exposures
to
unspecified
substances
and
resulting
implications.

discussion
regarding
cumulative
effects
of
exposure

multiple

Pipeline

along
their
right-of-

to
indicate
the

and
the

in

of
its
assertion
that
the
