Risk-based
remediation
goals
will
be
set
for
all
constituents
of
concern
that
have
been
identified
at
levels
higher
than
those
determined
by
the
RWQCB
or
DTSC
to
be
protective
of
human
health
for
the
land
uses
approved
by
the
City
for
the
Baylands.
Please
see
for
discussion
regarding
the
remediation
and
landfill
closure
review
and
approval
process.
As
discussed
in
that
Master
Response,
the
RWQCB
and
DTSC
have
the
statutory
authority
to
set
risk-based
remediation
goals
and
to
oversee
Title
27
landfill
closure
and
site
remediation.
The
Draft
EIR
reaches
no
conclusions,
nor
does
it
make
any
assertions,
regarding
the
community’s
attitude
toward
the
RWQCB’s
and
DTSC’s
role
in
site
remediation
and
Title
27
landfill
closure
or
toward
any
particular
remediation
method.

Ultimately,
the
regulatory
authority
and
responsibility
to
determine
specific
remedial
technologies
to
be
undertaken
within
the
Baylands
lies
with
the
RWQCB
and
DTSC.
As
stated
in
the
Draft
EIR,
cleanup
levels
approved
by
the
RWQCB
may
not
reflect
drinking
water
standards
because
the
groundwater
basin
is
not
used
for
domestic
water
supply
(drinking
water).
See
for
discussion
of
groundwater
cleanup
standards.
See
13
for
discussion
of
the
review
and
approval
process
for
site
remediation
and
5
for
discussion
of
compliance
with
the
law
as
mitigation
under
CEQA.
The
regulatory
authority
and
responsibility
to
determine
risk-based
cleanup
goals
and
the
specific
remedial
technologies
to
be
undertaken
to
meet
those
goals
lies
with
the
RWQCB
and
DTSC.
See
for
discussion
of
cumulative
effects
of
multiple
toxins
and
for
discussion
of
the
remediation
review
and
approval
process.
Human
health
risk
assessments
assess
the
cumulative
risks
due
to
exposure
to
all
constituents
detected
at
least
one
time
in
the
media
sampled
to
human
health
and
the
environment.
The
technologies
cited
in
this
comment
are
potential
treatment
technologies,
not
proposed
treatment
technologies,
that
may
be
employed
within
the
Baylands.

authority
and
responsibility
to

lies
with
the
RWQCB
and

They
are
identified
in
the
EIR
to
maximize
public
disclosure
of
potential
treatment
technologies
that
could
be
considered.
