Comments
from
Organizations
sources
of
TACs
such
as
Santa
Fe
Pacific
Pipeline
(Kinder
Morgan),
which
generates
benzene.
The
U.S.
EPA
has
established
requirements
for
a
new
monitoring
network
to
measure
NO
2
concentrations
near
major
roadways
in
urban
areas
with
a
population
of
500,000
or
more.
Sixteen
new
near-roadway
monitoring
sites
will
be
required
in
California,
three
of
which
will
be
in
the
Bay
Area.
These
monitors
have
only
recently
been
deployed.
Additionally,
the
U.S.
EPA
has
established
requirements
for
a
new
monitoring
network
to
measure
SO
2
concentrations
to
be
operational
by
January
2013.
No
additional
SO
2
monitors
are
required
for
the
Bay
Area
because
BAAQMD
jurisdiction
has
never
been
designated
as
non-attainment
for
SO
2
and
no
SIP
or
maintenance
plans
have
been
prepared
for
SO
2
(BAAQMD,
2013).
The
U.S.
EPA
revised
the
monitoring
requirements
for
lead
in
December
2010.
These
requirements
focus
on
general
aviation
airports
and
large
urban
areas
resulting
in
an
increase
in
76
monitors
nationally
(USEPA,
2010).
Lead
monitoring
stations
in
the
Bay
Area
are
located
at
Palo
Alto
Airport,
Reid-
Hillview
Airport
(San
Jose),
and
San
Carlos
Airport.
Non-airport
locations
for
lead
monitoring
are
Redwood
City
and
San
Jose.
Intermune
operates
a
permitted
back-up
diesel
generator.
Emergency
generators
are
operated
approximately
once
a
week
for
maintenance.
Within
the
Bay
Area,
air
pollutant
emissions
of
NO
2
and
SO
2
are
primarily
a
concern
from
petroleum
refineries.
Table
4.B-1
shows
that
the
current
State
standard
for
NO
2
is
being
met
in
San
Francisco.
The
Bay
Area
Air
Basin
has
never
been
designated
as
non-attainment
for
SO
2
.
Acidification
of
ecosystems
is
primarily
a
concern
as
a
result
of
emissions
from
coal-fired
power
plants
that
do
not
exist
in
the
Bay
Area.
Consequently,
air
pollutant
emissions
from
development
under
the
Project
Site
development
scenarios,
which
would
primarily
be
related
to
combustion
of
vehicle
fuels
natural
gas
and
potentially
biogas,
would
not
result
in
adverse
effects
due
to
acidification
or
other
substantial
ecological
degradation.
Impacts
from
PM
10
are
addressed
in
the
Draft
EIR
by
comparing
daily
or
annual
emissions
generated
by
Project
Site
development
to
thresholds
developed
by
the
BAAQMD
(82
pounds
per
day
and
15
tons
per
year).
However,
BAAQMD
developed
separate,
concentration-based
thresholds
specifically
for
localized
exposure
to
PM
2.5
The
localized
Thresholds
of
Significance
focus
on
PM
2.5
because
more
so
than
PM
10
,
these
emission
types
pose
significant
health
impacts
at
the
local
level
(BAAQMD,
2012).
Compelling
evidence
suggests
that
PM
2.5
is
by
far
the
most
harmful
air
pollutant
in
the
Brisbane
Baylands
