QUESTION:
How serious is the toxic and radiological contamination
of the Hunters Point Shipyard?
ANSWER:
The Shipyard is a seriously contaminated facility
and is on the National Priorities List. This means
it is among the most polluted of federal properties.
It is also the most seriously contaminated military
base on San Francisco Bay. On the other hand, the
Shipyard is in the lesser half of facilities on the
National Priorities List. Therefore, while the Shipyard
is seriously contaminated, there are many military
bases that pose a much greater risk to those working
on it and the surrounding community. Click

of contamination found on each of the parcels of Hunters
Point Shipyard.
QUESTION:
Does the Shipyard currently pose a hazard to its tenants,
residents of the Bayview Hunters Point Community,
and the City of San Francisco?
ANSWER:
This question is difficult to answer. Here’s
why: For a toxic or radioactive substance to pose
a health risk, a person needs to be exposed to a certain
amount of the contaminant over a certain amount of
time. Small amounts of mildly toxic chemicals over
a short period of time may have no impact whereas
a similar amount of highly toxic chemicals over the
same period of time may have a substantial impact
on health. The impact of exposure on the body also
varies from person to person as well as between races
and ethnic groups. So while exposure to the radium
from the radium painted dials disposed of on Parcel
E of the Shipyard could eventually cause death, it
only becomes a risk to a person’s health when
he or she is directly exposed in a manner that would
enable the substance to contaminate their body.
As a result, the population most at risk is those
who work on the Shipyard. This does not however mean
that it is not safe to work on the Shipyard. Again,
it is the amount and length of exposure that affects
a person’s health. Because much of the contamination
of the Shipyard is buried, the risk of exposure is
reduced. On the other hand, as cleanup continues and
trenches are dug there is more of an opportunity for
dust born toxics and radioactive substances to contaminate
nearby individuals.
The
next group with the possibility of an elevated risk
are those people living within Bayview Hunters Point,
bounded by Evans to the North, Thirds Street to the
West and Jamestown to the South. This is because toxic
and radiologically contaminated dust blown off-site
by the wind can be carried some distance. As BVHP
residents know, the winds in that area are strong
and can blow in a wide variety of directions. Also
increasing the possible exposure from airborne contaminated
dust are semi-trucks carrying contaminated materials
for disposal that have not been properly washed down
or have not properly put on their bin tarpaulin, if
at all. Like children running in from playing in a
sand box or backyard dirt, if not properly washed
down, a truck carrying contaminated material will
drop contaminated dirt and dust along its route. If
the tops of bins hauling waste have not been secured
with a tarp to keep the contents inside, the wind
and the movement of the vehicle can blow them into
the lots along the route.
Even
the risk within this area varies. People living closer
to the Shipyard, for example along Kiska or at Mariners
Village, will have a greater risk of exposure than
people living closer to Third Street. Escaping methane
gas from the Parcel E landfill threatens not only
people on the base near the sites, but also potentially
people on the hillsides above. Another source of exposure
for neighborhood residents, including those living
outside of the bounds of the area described above,
is eating fish and shellfish caught offshore of the
Shipyard. Seafood, particularly shellfish, caught
around the Shipyard has a good potential for being
contaminated. Click

in the South Basin.
SF
residents outside of the areas above stand a much-reduced
chance of being contaminated by the facility. While
landfill fires can carry pollutants some distance,
the heavier and middleweight particles typically fall
within a mile or so from the site, lighter particles
are carried some distance. As a result, it is more
than likely that the impacts of the Shipyard even
in an event similar to the August 2000 – April
2001 landfill fire would have limited negative impacts,
if any, on community health outside of the BVHP neighborhood.
QUESTION:
What about past activities, such as the burning of
radioactively contaminated fuel oil in Shipyard power
plants: did that contaminate tenants, residents of
the Bayview Hunters Point Community, and the City
of San Francisco?
ANSWER:
This is another difficult question to answer.
The most honest response to the question is: we don’t
know, but it is possible. Numerous activities have
occurred at the Hunters Point Shipyard, which could
have had an impact on the health of residents within
the 94124 district. Burning radioactively contaminated
fuel oil, for example, will not remove the radioisotopes.
Burning simply moves the contaminants from the oil
into the air. How far and wide they were then spread
is anyone’s guess because the data that exists
on BVHP wind patterns doesn’t reflect its numerous
micro-climates or frequent and sudden shifts in direction.
QUESTION:
What is a Restoration Advisory Board and what does
it do?
ANSWER:
A Restoration Advisory Board, or RAB, is a community
advisory committee established by the Navy to solicit
community input on cleanup decision-making. RABs do
not have decision-making authority, but do have influence
within the process. Click
here to learn more about the RAB.
QUESTION:
If the RAB doesn’t make the cleanup decisions,
who does?
ANSWER:
The Base Cleanup Team or BCT makes these decisions.
The BCT is composed of the Navy, US EPA, the California
Department of Toxic Substances Control and San Francisco
Bay Area Regional Water Quality Control Board. The
Navy is the “lead agency” so under the
Superfund process, it gets to determine what it will
do and how much it is willing to spend on the cleanup.
Nevertheless, the regulators can approve or disapprove
of the plan and order the Navy back to the drawing
board if they don’t like a proposed cleanup
strategy. Click
here for more information on the cleanup process.
QUESTION:
What is the City of San Francisco’s role in
the cleanup process?
ANSWER:
The City of San Francisco has a very limited role
under the Superfund program. As the local governmental
entity that is taking over the Shipyard, the Navy
must negotiate with the City over the cleanup standards
it is willing to accept. However, the federal government
is under no obligation to comply with those standards.
As a result, the City of San Francisco has attempted
to conclude a Conveyance Agreement with the Navy,
which will bind the federal government to cleanup
standards that are consistent with the planned reuse
for the Shipyard and are consistent with the intent
of Proposition P. Otherwise the City, like any other
interested party, has had to hire its own consultants
and staff to monitor the environmental cleanup process
at the Shipyard to ensure its goals are addressed
during the deliberations of the Base Cleanup Team.

QUESTION:
What is the Hunters Point Shipyard Citizens Advisory
Committee and what does is do?
ANSWER:
Like the Restoration Advisory Board, the Hunters Point
Shipyard Citizens Advisory Committee, or HPS CAC,
is a community advisory committee established to solicit
community input on the Reuse of the Shipyard. The
CAC addresses cleanup decision-making as they affect
the reuse of the property. Click
