ROG
(Reactive
Organic
Gases)
(page
4.B-18)
or
volatile
organic
compounds
are
as
defined
in
40
CFR
Part
51
Section
51.100
as
any
compound
of
carbon,
excluding
carbon
monoxide,
carbon
dioxide,
carbonic
acid,
metallic
carbides
or
carbonates,
and
ammonium
carbonate,
which
participates
in
atmospheric
photochemical
reactions.
This
includes
any
such
organic
compound
other
than
those
identified
in
40
CFR
Part
51
Section
51.100
(1)
,
which
have
negligible
photochemical
reactivity.
Topographical
change
(page
4.C-1)
Although
this
term
does
not
appear
on
page
4.C-
1,
depending
on
the
context
of
its
use,
“topographical
change”
refers
to
differences
in
topography,
such
as
differences
between
hillside
and
flat
valley
lands,
or
differences
in
elevations
that
would
occur
as
the
result
of
site
grading.
Native
soil
(Section
4.D)
refers
to
soils
native
to
the
site
that
were
not
placed
by
humans
to
fill
the
Bay
or
to
cover
pre-existing
soils.
Clean
soil
(page
4.E-1)
The
term
“clean
soil”
is
a
common
term
used
in
the
construction
industry
to
denote
soils
that
are
free
of
rubble
and
construction
debris.
As
used
in
the
Draft
EIR,
it
refers
to
the
20
to
30
feet
deep
layer
of
soil
used
as
final
cover
over
the
landfill
to
prevent
human
contact
with
refuse
from
residential,
commercial,
industrial
activities
including
shipyard
waste,
construction
rubble,
tires,
and
sewage.
Primarily
(with
respect
to
Old
Bay
Mud
and
New)
(page
4.E-1)
as
used
with
respect
to
the
location
of
Bay
Mud
soils
refers
to
the
locations
at
which
the
Bay
Mud
soils
unit
is
most
commonly
present
at
shallow
depths
(along
the
Bay
shoreline
and
lagoon
perimeter).
Typical
(page
4.J-4,
page
4.E-25)
“Typically,”
as
used
on
page
4.E
-25
and
page
4.J-4
is
interchangeable
with
“in
general.”
Breached
(page
4.E-38)
,
as
used
on
page
4.E-38
means
pierced.
Over
consolidated
(page
4.E-45)
“Consolidation”
refers
to
the
reduction
in
volume
of
a
soil
unit
when
loading
(such
as
fill
or
a
building)
is
placed
on
top
of
it.
When
stress
is
removed
from
a
consolidated
soil,
the
soil
will
rebound,
regaining
back
some
of
the
volume
it
had
lost
in
the
consolidation
process.
If
the
stress
is
reapplied,
the
soil
will
consolidate
again.
The
soil
which
had
its
load
removed
is
considered
to
be
over-consolidated
.
Well-defined
aquifer
(page
G-24)
is
defined
as
an
aquifer
between
two
distinct
layers
of
earth
that
“confine”
the
aquifer
of
interest.
Such
an
aquifer
would
be
readily
visible
in
a
cross
section
obtained
from
multiple
boring
logs.
BMPs
(Section
4.H)
is
the
acronym
for
“
best
management
practices.
”
In
relation
to
stormwater
management,
BMPs
are
control
measures
taken
to
mitigate
changes
to
both
quantity
and
quality
caused
through
changes
to
land
use.
BMPs
are
designed
to
reduce
stormwater
