Introduction. Our
Barron Park neighborhood borders the Stanford Research Park. This interface is overdue for an update to the Performance
Standards to regulate and guide its development. The Planning
Commission and the Staff deserve credit, in particular Curtis Williams with
whom we have been discussing this issue for over six months, for their
constructive efforts. By planning projects appropriately ahead of time,
mistakes and bad decisions don’t happen, the kind of mistakes that bring
aggravation to residents and require costly corrective actions by the
businesses.
The Performance Standards proposal
also includes, for the very first time, a specific component addressed to
Hazardous Materials. Over the years, actions at various times by the
businesses operating in the Stanford Research Park with hazardous materials
have created unsafe conditions for residents who live nearby. The proposal on Hazardous Material from the Planning
Commission recognizes that some restrictions are required, but it does not go far
enough.
We have three specific
recommendations we would like the Council to accept.
Background. Over the past twenty years, there has been a heightened awareness of environmental issues by businesses and the city, and an overall strengthening of city and state regulations. Most of the companies that were the sources of the hazardous materials releases and who contaminated our underground waters in the past have changed their ways, left the Stanford Research Park or moved those activities elsewhere.
However there is one exception. Those
of us with homes close to CPI feel we are living with a dangerous situation,
with a great risk to the health and safety of our neighborhood should there be
an accident or a natural disaster that would release the hazardous chemical
materials stored there. Varian built this plating shop and associated hazardous
materials storage facilities. Even though the houses were already there, Varian
positioned them at the very back of their site, which meant they are as close
to the residences as they could possibly be. The plating shop is on the side of
the building facing the houses and the hazardous chemical bunker storage area
is against the back wall of the CPI site that abuts the residential zone.
This situation had developed years
ago for historical reasons. Many current residents were not aware of the level
of risk to them and their families from an accident - until recently. Varian reorganized in 1995 and the facility
is operated by CPI as a manufacturing site, not as a research and development
center. Two years ago, CPI decided to consolidate all of its California
manufacturing operations in Palo Alto and closed its facility in an industrial
area of San Carlos. Without any notification to the residents, the Planning
Department allowed the facility next to Barron Park to rebuild to increase its
manufacturing capacity and increase its inventory of extremely hazardous
materials. We engaged with the Planning
Department last spring and participated in many meetings and actions with the
Planning Commission this past fall to help develop a set of Performance
Standards that would, among other things, not allow this set of events to
happen again.
Regulations of Hazardous Materials and Offsite
Consequences. Many of us were
blindsided by the accident at CPI when toxic fumes drifted into our
neighborhood last February. We have educated ourselves and we are aware of the
large amounts of extremely hazardous materials used and stored by CPI just over
the back fence from residences on Chimalus Drive. Following the accident, we became aware of the critical situation in
the event of a catastrophic accident. We learned of the Community Right to Know
Laws, the Clean Air Act and the pioneering legislation in California in the
early 90’s that began to require identification of facilities where extremely
hazardous materials are stored in such large amounts that an accidental release
could endanger the public outside of the site boundaries. All of these laws
were the outgrowth of the Bhopal disaster in India in 1986, when thousands of
individuals were killed and thousands more maimed off site by a toxic gas plume
from a Union Carbide chemical plant. In
California, the federal and state programs were consolidated into the
California Accidental Release Prevention Program (CalARP), in 1999 and final
regulations were promulgated by the State of California in 2004 as Title 19.
Title 19 Regulations. The Title 19 regulations identify a set of extremely
hazardous materials and threshold levels. Sites that use and store any of these
materials above the threshold levels are subject to this program. There are 25
facilities that fall under this program in Santa Clara County, which is
administered by the Department of Environmental Health. Only two are in the
city of Palo Alto: one is the waste water treatment plant near the Bay; the
other is CPI near the residents of Barron Park. The presence of a manufacturing
facility using hazardous materials above Title 19 thresholds within 100 feet of
residences in Palo Alto nowadays would be considered an example of atrocious
and reckless zoning.
CPI is a Title 19 facility because
it uses and stores two hazardous chemicals above Title 19 thresholds: nitric
acid and potassium cyanide. They are required to file a Risk Management Plan,
or RMP, which contains several required elements. One of these is a disclosure
of the amounts of extremely hazardous materials on their site. In 2004, CPI had
3200 lbs of nitric acid. This was three times the Title 19 threshold of 1000
lbs. In 2006, CPI had increased the amount of nitric acid to 4160 lbs, or more
than four times the Title 19 threshold.


The provision in the Performance
Standard proposal would allow them to increase this by another 25% to 5200 lbs,
or more than five times the Title 19 threshold. In 2004, CPI disclosed it had
402 lbs of potassium cyanide on its site, mostly in solution, but more than 100
lbs in a storage drums. The total is already four times the Title 19 threshold
of 100 lbs. In 2006, after the reconstruction of their manufacturing facility,
CPI disclosed they had increased the amount of potassium cyanide on their site
to over 630 lbs, more than a 50% increase. If they were allowed another 25%
increase above the 2006 amounts, they would have almost 800 lbs of potassium
cyanide or eight times the Title 19 threshold.
CPI uses and stores acid and
potassium cyanide in the same plating shop and in the same general storage
areas. They are required to keep these materials strictly separate, but in a
natural disaster or if there were a serious malfunction of their equipment, the
materials could spill and combine and that would produce hydrogen cyanide gas,
one of the most toxic of all gases. It is all the more dangerous because it
does not have an acrid, irritating odor that makes people quickly aware of the
existence of a dangerous situation.
The US Department of Health and Human Services has published
"Medical Management Guidelines" for hydrogen cyanide ( http://www.atsdr.cdc.gov/MHMI/mmg8.html). The
guidelines point out that the odor does not provide adequate warning of
hazardous concentrations (and it is estimated that 20-40% of the population
cannot even smell it). Symptoms of poisoning can begin within
seconds to minutes, and hydrogen cyanide poisoning can produce death in
minutes. "Hydrogen cyanide poisoning is marked by abrupt onset
of profound toxic effects that may include syncope, seizures, coma, gasping
respirations, and cardiovascular collapse, causing death within minutes."
So it is clear why we say that CPI
has extremely large quantities of extremely hazardous materials literally just
over the back fence from residences on Chimalus Drive.
The Possible Consequences of an Accidental Release
at CPI. The health and safety of a
large number of people in Barron Park is imperiled by an accidental release of
hazardous materials at CPI. Accidental releases can occur because of human
error, equipment failure, industrial sabotage, an act of terrorism or a natural
disaster such as an earthquake. Earthquakes in particular are a significant
concern because the entire emergency response scenario assumes that the
Hazardous Response Unit of the PAFD would be able to respond immediately. In
the case of a major earthquake, we do not have any idea of how long it would
take for the PAFD to respond, nor what their first priority would be when they
would be able to respond. A study
published by researchers (Joint
Seismic and Technological Disasters: Possible Impacts and Community
Preparedness in an Urban Setting, by L.J. Steinberg, V. Basolo, R. Burby,
J.N. Levine, and A.M. Cruz, Natural Hazards Review, Vol 5, pp 159-169, Nov
2004) states that “ If these releases occur near residential
communities, large numbers of people are placed at risk and simultaneously must
cope with the effects of the earthquake…even in a community with a substantial
community outreach program, many residents are under prepared for an
earthquake, hazardous materials release, or a conjoint disaster.”
Title 19 requires companies to
identify what they consider serious accident scenarios in that would lead to
releases of hazardous materials in their Risk Management Plan. CPI considered that one of the tanks of
plating liquids or acid might rupture or the storage drum of potassium cyanide
spills and combines with acid stored nearby. Once an accident scenario
is defined, the extent of the offsite consequences is determined using
standardized rules and computer models allowed for by the Title 19 regulations.
These rules include assumptions on the weather and the wind. The conditions
could vary, and in addition, an accident could actually
involve multiple tanks, so the accident and the consequences could be worse
than what is in the RMP. The event that led to the release of nitric acid
vapors on Feb 2nd from CPI was not in any of the accident scenarios in
their Risk Management Plan. It proves the point that you can’t predict all
accidents – you can hope for the best,
but you must prepare for the worst.
In any event, the accident scenario and the offsite consequences that CPI disclosed in their RMP provide an example of what the impact of a serious accidental release would be to the community. The definition of the affected area is in the 2nd paragraph of the 18.23.100 (v) in the proposal of Hazardous Materials. For toxic gas releases, the affected area extends to what is called the ‘toxic endpoint.’ The following figure shows the area that could be affected by toxic vapors from a serious accident that sent nitric acid vapor or hydrogen cyanide vapor fumes into the air.
The circle extends about 1000’ ft, 1/5 of a
mile. We call this the Barron Park Danger Zone. There are actually two circles, depending upon whether the release
were to occur in the plating shop or in the chemical storage area. Within the
circle are over 125 homes, several apartment buildings, and for the zone
surrounding the chemical storage area,
a hotel and businesses along El Camino. We are talking about hundreds of
residents – not to mention the workers at CPI and in adjacent buildings if the
release occurred during working hours. Those closest to the accident center would
be very severely affected and may not survive. Those at the edges and beyond,
depending upon the wind and weather, would most likely not suffer permanent
injury.
Assessing Risk of a Title 19 Facility Title 19 rules are regulations on
registration of hazardous materials; they identify the facilities where
releases could affect the general public off site. They do not limit the
amounts of hazardous materials a facility may store, nor do they quantify the
risk, but they do clearly identify the hazard. It is the role of the zoning regulations to consider the hazard when it
comes to Title 19 facilities and to make decisions that would limit the risk.
Summary and Recommendations. Our first recommendation is that you to strike out that provision allowing for a 25% increase in materials used and stored by CPI that are already above Title 19 threshold limits.The provision in section 18.23.100 (vi)(b) of the Performance Standards proposal pertains to facilities that already have hazardous materials above Title 19 thresholds and are within 300’ of residential property line. There is only one such facility in Palo Alto that this would apply to, and it is CPI. The risk to our health and safety from an accident at CPI would be raised even further should CPI be allowed to increase the amounts of hazardous materials above Title 19 threshold limits by an additional 25%. Because of the risk the present amounts of hazardous materials pose to residents, any further increase is unacceptable. We think the risk is already too high. Allowing a 25% increase would only make a very bad situation even worse.
Second, we feel that
facilities with hazardous materials above Title 19 thresholds present such
serious risks to the community from an accidental release that it sets them
distinctly apart from other sites that use hazardous materials. The State of
California created these Title 19 regulations for exactly that purpose. We feel
that the city should consider very carefully before allowing any site in the
future with Title 19 facilities to operate in Palo Alto. We propose that the
City Council set regulations for allowing Title 19 facilities that are
commensurate with the risk they present. The City Council itself
should approve any application for a new Title
19 facility in Palo Alto, or when existing facilities propose
increasing their inventory of hazardous materials above the Title 19
thresholds.
However, as long as CPI uses and stores such large amounts hazardous materials so close to our homes, our neighborhood is vulnerable. We face the risk of a large toxic release that would be tantamount to a disaster. There are ways to reduce the consequences of future accidents and natural disasters – like improving structural integrity of buildings before an earthquake strikes. Similar pro-active measures would reduce the possibility of any future toxic chemical release turning into a major disaster.
Our third recommendation is for the City Council to establish a policy that would induce CPI to lower its dependence on extremely hazardous materials. The plating materials and processes used by CPI were developed in the middle of the 19th century. There are better, cleaner and more environmentally friendly ways to do this type of work. We think the city should encourage CPI, if it wants to stay in Palo Alto, to innovate and adopt more modern and safer methods and materials. Over time, CPI would reduce the amounts of extremely hazardous materials it uses and stores so that in some reasonable time frame, say three years, it would no longer be subject to the California Title 19 regulations. There are a number of ways to achieve this. The city could set some benchmarks in the code, and convene a group of outside experts who would work with the facility to help it innovate and adopt more modern methods. Because the hazardous materials CPI uses are costly to purchase, costly to store and use, and costly to dispose of, we are convinced that this initiative would be in the long term business interest of CPI. At the same time this would advance the health and safety of the surrounding community.
In conclusion, we feel the risk is
clear – we feel we are already in a dangerous situation. Increasing the amount
of hazardous materials in our backyards is unacceptable. We want the council to
roll back the provision that would allow CPI to increase the amounts of
hazardous materials it has above Title 19 thresholds by a further 25%. We also
would like there to be a provision in the zoning code that would require the
City Council itself to give approval to any new Title 19 facilities anywhere in
Palo Alto. And we want the Council to give a clear signal to CPI that city of
Palo Alto wants to work with it to reduce its hazardous materials and thereby
lower the risk of a disaster associated with a chemical release to the
neighboring community.
