UC Berkeley Richmond Field Station
Remediation and Restoration
Frequently Asked Questions |
|
| |
|
| SITE BACKGROUND |
|
| |
|
|
| Q. What is the Richmond Field Station
(RFS)? |
|
The RFS is an ~ 150 acre parcel owned by the University
of California (UC) located in Richmond, about five miles from the
central UC Berkeley campus. It was purchased in 1950 and is used primarily
for College of Engineering academic teaching and research activities,
but also houses some non-UC tenants. Current uses include the Northern
Regional Library Facility, laboratories for other campus departments,
including Art Practice, and EPA’s Region 9 Laboratory. The RFS
also contains unique natural resources, including a remnant coastal
terrace prairie and tidal marsh that is home the endangered California
Clapper Rail. Additional background material about the RFS is available
at http://rfs.berkeley.edu/about.html.
|
|
| |
|
|
| Q. Why is remediation needed at the
RFS? |
|
| Industrial activities that occurred prior to UC ownership
led to the majority of contamination found at the RFS. |
|
| |
|
|
| The three main pollutant sources were: |
|
| |
- The California Cap Company (the former site owner), which manufactured
mercury fulminate for blasting caps from the 1870s to 1940s on
what is now the RFS property.
- Stauffer Chemical Company, acquired by Zeneca Inc., which operated
on property adjacent to the RFS from 1919-1962. Stauffer Chemical
manufactured sulfuric acid, pesticides and other chemicals. This
neighboring property is now owned by Cherokee-Simeon Ventures,
LLC, also known as "CSV."
- An unknown source of polychlorinated biphenyls (PCBs)
|
|
| Q: Is the neighboring “Campus
Bay” site owned by or connected to UC Berkeley? |
|
| No. “Campus Bay” is the name Cherokee-Simeon
Ventures, or "CSV," has given to the site formerly owned
by Stauffer/Zeneca, which is adjacent to RFS. It is a private development
unaffiliated with UC Berkeley. |
|
| |
|
|
| Q: What are the contaminants found
on the UC Berkeley Richmond Field Station (RFS) site? |
|
The main contaminants are the metals mercury, lead and
copper from the California Cap Company operations.
|
|
| |
|
|
| Pyrite cinder waste (waste from sulfuric acid production)
that includes an assortment of metals (arsenic, cadmium, copper, lead,
mercury, selenium and zinc) and creates low pH (acid) conditions,
was deposited by Stauffer Chemical Company in the early 1900s. |
|
| |
|
|
An isolated spot of PCB contamination was found at the
outfall of the Western Storm Drain in Meeker Slough and was cleaned
up in 2003, although detectable PCBS remain in some other locations
at RFS.

|
| CLEANUP / RESTORATION ACTIVITIES |
|
| |
|
|
| Q: What has UC Berkeley done about
the contamination at RFS? |
|
| UC Berkeley has established a multi-year program to
remove contaminants and dispose them off-site at approved treatment
and disposal facilities. |
|
| |
|
|
| Work began in 2002 with removal of the largest areas
of contaminated soils, which were excavated, treated, and transported
off-site. Excavated areas are replaced with clean bay mud or clean
dirt for re-planting with native marsh and coastal prairie plants. |
|
| |
|
|
| The project has been divided into multi-year phases
to protect the endangered California Clapper Rail. Work in the marsh
is prohibited by the US Fish and Wildlife Service from February 1
through August 31, the breeding season for this very rare bird. |
|
| |
|
|
Q: If UC Berkeley is not the source
of the contamination at RFS, why is it paying for the site cleanup
and marsh restoration?
|
|
UC assumed the liability for materials left by the previous
landowner, the California Cap Company, when the property was purchased
in 1950. Because the California Cap Company went out of business around
the time of purchase, there are no assets that UC can attempt to recover
for payment toward the cleanup. However, UC is paying for only a portion
of the RFS cleanup. UC is working with agencies to identify any responsible
parties who should pay to remove contamination on the site that resulted
from their activities.
|
|
| |
|
|
| Q: How will the contaminated areas
at the RFS be cleaned up? |
|
The contaminated soil on UCB property is being excavated,
treated and sent for off-site disposal at permitted landfills. Hazardous
waste is being sent to the Kettleman City Class 1 Hazardous Waste
Landfill. Other non-hazardous wastes are being sent to the Keller
Canyon landfill. Clean soil is being reused on-site. Any soil left
in the remediation areas or brought in to use as clean fill has been
tested extensively and approved for use by applicable government agencies.
|
|
| |
|
|
Pyrite cinders that were deposited in the 1940s by Staffer/
Zeneca on what is now UC property were removed to the Zeneca site
for management by Zeneca.
|
|
| |
|
|
Q: How long will the construction work
at the RFS continue? When will the cleanup work be completed?
|
|
Active remediation is scheduled for completion in 2007.
Restoration work and monitoring is expected to continue until at least
2013.
|
|
| |
|
|
| Q: Which agency is overseeing the
RFS remediation/restoration project? |
|
| The San Francisco Bay Regional Water Quality Control
Board was the lead oversight agency from 2001 until May 2005, when
the California Environmental Protection Agency announced that the
state's Department of Toxic Substances Control (DTSC) would assume
the role as lead regulatory oversight agency for RFS remediation and
wetlands restoration work. The agencies are now in the process of
transferring oversight in accordance with the Cal EPA decision. |

|
| HEALTH AND SAFETY QUESTIONS |
|
| |
|
|
| Q: Are any of the chemicals at RFS
harmful to my health? |
|
During normal activities — such as working in
offices and labs, walking and bicycling around the RFS, driving to
and from work — RFS occupants and visitors would not have contact
with the contaminants, most of which are in the marsh, to put them
at risk. If a person were exposed to sufficient amounts of heavy metals
and PCBs through ingestion (eating), inhalation (breathing) or skin
absorption, however, it could be harmful to his or her health.
|
|
| |
|
|
| Anyone wishing to use the RFS for activities that could
disturb soil or impact sensitive natural resources must obtain approval
for that use by submitting a written proposal. Call RFS operations
at (510) 665-3401 for a copy of the Facility Usage Guidelines. |
|
| |
|
|
| In June 2005, officials from the California Department
of Health Services and the Contra Costa County Health Services Department
released a "Provisional Joint Health Statement Summary"
concerning remediation activities at the RFS and adjacent Zeneca site
(formerly Stauffer Chemical Company). This information is available
online at: http://www.ehib.org/cma/index.jsp
or by going to http://rfs.berkeley.edu. |
|
| |
|
|
| Q: Is the air at RFS safe to breathe? |
|
| Yes, all air sampling performed to date has indicated
that the air is safe. UC Berkeley’s Office of Environment, Health
& Safety and its consultants have conducted extensive air quality
sampling during RFS cleanup activities. Air monitoring is performed
for appropriate organic chemicals, metals and particulate matter.
In addition, Zeneca performed sampling while work was occurring on
their property adjacent to RFS. DTSC, the agency overseeing the Zeneca
cleanup, also sampled the air during Zeneca's remediation activities.
|
|
| |
|
|
| RFS air monitoring data is available at http://rfs.berkeley.edu/air_monitoring.html.
Data for the Zeneca site is available at http://www.dtsc.ca.gov/SiteCleanup/Zeneca/index.html
and http://www.campusbay.info. |
|
| |
|
|
| Sampling will be performed per DTSC order when additional
clean-up work is performed at either the RFS or Zeneca site. |
|
| |
|
|
| Q: How can UC Berkeley be sure
that the construction activities for the cleanup (digging and moving
soil) aren't putting people’s health at risk? |
|
| All work has been done under permits issued by several
government agencies and with oversight by the Regional Water Quality
Control Board. The Regional Board has reviewed and approved plans
for cleanup activities to date and the DTSC will do so in the future.
During remediation work, UC's environmental consultants are on site
providing assurance that the work is being performed in accordance
with plans approved by the government oversight agency, and in such
a manner that no one's health — including that of any remediation
worker — is jeopardized. There have been several layers of oversight
during remediation, including three consulting firms, the environmental
contractor, and UC Berkeley’s Office of Environment, Health
& Safety. |
|
| |
|
|
| In addition, as described previously, extensive air
monitoring is performed during RFS remediation activities. |
|
| |
|
|
| Q: What can RFS staff do if they
have concerns about health problems and want to know if they are related
to the remediation work? |
|
| There are several possible options if you feel you have
symptoms related to your work environment, including: |
|
| |
|
|

|
|
| NEW Q:
What is arsenic, and why would it be present at the RFS?
|
|
| Arsenic is a naturally occurring element present in
Bay Area soils in concentrations of 5 to 20 mg/kg (parts per million).
As such, it is expected that soil and dust samples will contain some
background levels of arsenic. Ambient air is also expected to contain
arsenic in background concentrations ranging from 0.04 to 1.0 µg/m3.
According to the U.S. Department of Labor Occupational Safety and
Health Organization (OSHA), the permissible occupational exposure
limit to arsenic is 10 µg/m3.
Impacts on human health can be seen with exposure to (ingestion,
inhalation and skin contact) elevated levels of arsenic, which can
occur in areas with significant arsenic pollution or abnormally
high natural soil or water concentrations of arsenic.
Arsenic is also found as a naturally occurring constituent of iron
sulfide ore (pyrite), which was used for manufacturing sulfuric
acid at the former Stauffer Chemical Company, a property now owned
by Zeneca, a private development not associated with UC Berkeley.
Arsenic is thus present in the pyrite cinder manufacturing waste
product, which was discarded in Stege Marsh.
|
|
| |
|
|
| NEW Q:
Were hazardous levels of arsenic found in RFS air samples? |
|
| No. As part of the recently established Supplemental
Air Monitoring Program , the campus Office of Environment, Health
& Safety (EH&S) completed air monitoring for arsenic at various
locations at the RFS. In sampling taken to date, air concentrations
of arsenic are at or below naturally occurring background levels.
The following are results of the recent arsenic monitoring by EH&S:
• Aug. 16, 2005, Building 163: Arsenic concentration of 0.098µg/m3,
about a hundred times less than the level considered safe by OSHA
and in the range of expected background concentrations.
• Aug. 16, 2005, Building 175: Arsenic concentration of 0.085µg/m3,
about a hundred times less than the level considered safe by OSHA
and in the range of expected background concentrations.
• Sept. 20, 2005, Building 175: Arsenic levels below detection
limit of 0.03µg/m3.
• Dec. 6, 2005, Building 478, four locations: Arsenic levels
below detection limit of 0.03µg/m3. (On this date,
remediation activities were occurring at the neighboring Zeneca
property).
• Dec. 9, 2005, Outdoor Monitoring Station at Building 175:
Arsenic levels below detection limit of 0.03µg/m3.
(On this date, remediation activities were occurring at the neighboring
Zeneca
property)
|
|
| |
|
|
| NEW Q:
Are there harmful levels of solvent vapors in Building 478? |
|
| No. On Dec. 6, 2005, the campus Office of Environment,
Health & Safety (EH&S) sampled the air in Building 478, the
largely vacant former Forest Products Laboratory building. Monitoring
was conducted for perchloroethylene (PCE or perc), trichloroethylene,
vinyl chloride and arsenic. None of these chemicals was detected.
Recent plans to reoccupy Building 478, have led to concerns being
expressed about residual PCE contamination in soil and groundwater
from an area known as Lot 1 located on the neighboring Zeneca site.
Lot 1 was an area of historic industrial operations of the Stauffer
Chemical Company and Zeneca. Cleanup actions were completed by Zeneca
in 2001. In November 2001, the Regional Water Quality Control Board,
the regulatory agency overseeing the cleanup of Lot 1, approved
the cleanup and issued a No Further Action letter.
The Department of Toxics Substances Control, the state agency currently
overseeing cleanup of the Zeneca site, has required additional soil
and groundwater sampling. This website will be updated with new
information as it becomes available from DTSC.
|
|
| |
|
|
| NEW Q:
Are children being exposed to toxic mud in the marsh? |
|
| No. The activities of children and adult volunteers
assisting in plant restoration – including transplanting sprouts
and weeding – at Stege Marsh are closely monitored by the campus
Office of Environment, Health & Safety (EH&S) to ensure a
safe and productive educational experience.
In 2003, the University entered into a collaborative effort with
The Watershed Project, an independent, local nonprofit educational
organization focused on the San Francisco Bay estuary, to provide
high quality, field-based education and research programs for UC
Berkeley students, K-12 students from traditionally under-served
segments of the local community, and community partners (such as
Kids for the Bay, Earth Team, Save the Bay, Friends of the Estuary
and the East Bay Regional Park District). While working in Western
Stege Marsh, children have been restricted to working in imported
clean soils and Bay mud in an area known as the ecotone (the transitional
zone between the marsh and upland grasslands) or in upland grasslands.
All imported soils were sampled extensively to ensure they were
free of toxic contaminants.
By agreement with the Department of Toxics Substances Control,
the University restricts the work of children to clean, non-tidally
influenced areas of the marsh and uplands. Adult volunteers can
work unrestricted in tidally influenced portions of the marsh that
can contain pollutants such as bacteria and urban runoff. The University
requires use of gloves and boots for work in these areas.
Risk to an adult or youth working in the marsh was addressed by
the California Department of Health Services (DHS) and Contra Costa
County Health Services Department (CCCHSD) in their June 2005 Provisional
Joint Health Statement Summary for the Zeneca and UC Richmond Field
Station sites. At the June 22, 2005 hearing on the Provisional Health
Statement held at the Richmond Field Station, Dr. Wendell Brunner,
Public Health Director for CCCHSD, stated that the CCCHSD and DHS
were "confident" that the chemical concentrations in the
remediated portion of the marsh do not pose a current public health
hazard and that it was "not inappropriate for adults or kids
to be working there".

|
| FUTURE PLANS |
|
| |
|
|
| Q: What are the university's plans
for the site after cleanup is finished? |
|
| Restoration of the wildlife habitat and marshland is
very important, so the University plans include work and monitoring
to return the area to one that is friendly to migratory birds and
other flora and fauna. Future plans would maintain the environmental
integrity of native grasslands and wetlands. |
|
| |
|
|
| In addition, the University is interested in making
greater use of the RFS to further the teaching and research programs
of the Berkeley campus. The proposal is to use part of the RFS for
a multi-building scientific research campus, while encouraging and
enhancing selected existing scientific research activities located
on the property. There had been previous, informal discussions between
the University and developer Simeon Properties exploring a possible
joint venture to redevelop a section of the RFS. |
|
| |
|
|
| However, there are currently no discussions between
the University and any developer as plans for the future remediation
of RFS become settled. |
|
| |
|
|
| STAYING IN THE LOOP |
|
| |
|
|
| Q: How is UC Berkeley communicating
with the public? |
|
| The RFS project management team has been giving presentations
to the RFS staff, the Marina Bay Homeowners Association, local businesses,
and other interested parties since remediation began in 2002. The
Bay Trail was posted with a descriptive sign in 2002, and an updated
sign was installed in 2004. Written materials are also distributed
to interested parties, and a website is maintained to provide project
information and updates. |
|
| |
|
|
| The project team is available to meet with groups upon
request. During remediation at the RFS, weekly construction updates
are emailed and posted to the web. If you would like to receive those
updates via email, please send your address to Christine Shaff in
Capital Projects at cshaff@cp.berkeley.edu.
|
|
| |
|
|
| Q: How can I keep up to date on what
UC Berkeley is doing? |
