Shut Down Incinerator
L A Wood, Berkeley Voice, June 10, 1999
Marc Albert's story on Pacific Steel Casting Company should be corrected
to read that an incinerator was installed in 1998, and not 1989, at
the West Berkeley site. Many of those living under the cloud of PSC stacks are
quite surprised to read about the new incinerator since a Bay Area Air
Quality Management Board's "Unconditional Order of Abatement"
has been in force to reduce emissions and public nuisance since the
mid 1980s. Yet, last year, with the installation of the incinerator,
PSC's sitewide emissions rose substantially.
In fact, particulates increased 70 percent, nitrous oxides
35 percent, and carbon monoxide over 80 percent, along with increases
in formaldehyde, phenols, metals and organic compounds, when compared
to the last annual air-emissions report in 1997. The answer to the argument over whether the new equipment
is an incinerator or a bake oven is simple. Bake ovens generally operate
at 400 degrees - 500 degrees F, where as incinerators, typically burn
at much higher temperatures, like the one at PSC which burns at 1400
F.
The emissions from their respective stacks is also quite
different. Bake ovens produce large amounts of organics. This is reflected
in the other bake ovens on site for mold and casing manufacturing. PSC's
sitewide emissions for organics are over 37 tons annually. PSC's incinerator is supposed to produce less than 90
pounds of organics, but will also generate increased amounts of other
chemicals while processing 10,000 tons of sand annually. It's doubtful that this new incinerator would have been
allowed to operate if the community had been properly notified about
the project.
This incinerator was virtually hidden from the public
even though it was officially endorsed by Berkeley's mayor and the Economic
Development Office. It even won a state business award. Now the incinerator
project is being offered as a model for other Bay Area urban foundries.It's no wonder that so few are willing to look at this
pilot project critically, or to question its sustainability in any urban
environment.
The questions raised in public discussions during the
early 1980s resulted in some changes at PSC as they began to address
the nuisance odors from the site. However, the discussions about health impacts were simply
deferred, and to date, no complete health assessment has ever been completed. This is the unanswered question of the abatement order,
and is again raised by the public's discovery of the new incinerator.
What is the potential for causing serious illness to those living and
working around PSC from low-level and long-term exposure?
Despite two decades of community focus, we unfortunately
don't know much more about the atmosphere chemistry and dispersion,
the exposure pathways, the chemical compositions, or the chemical byproducts
associated with PSC's emissions. Back in 1982, the medical and chemical issues were tabled
for lack of scientific understanding. Today, we better understand the
carcinogenic aspects of PSC's emissions and how low-level exposure affects
health and human development. It's about more than unpleasant odors; it's about the
chemicals we don't smell and their effects on human health! This is
the missing piece in this failed regulatory process.
Frankly, there has never been a real commitment to the
understanding of the health impacts of air emissions by PSC, or by BAAQMD. Yet $1 million was invested to install an incinerator,
some of which was public money. BAAQMD, which originally stood with
the Berkeley and Albany communities in addressing this issue, now chooses
to hide behind PSC and some local officials. Moreover, a decade has
passed since the Department of Health Services first suggested that
a study and health assessment of PSC's emissions be undertaken. Where is their completed health assessment, one which
factors in the incinerator emissions? And where is DHS now the PSC is requesting relief from
BAAQMD's abatement order?
A health risk assessment must be conducted which directly
addresses long-term, low-level exposures, and its effects on residents
surrounding the facility. Let's begin with an ambient air station placed
in the childcare facility next to PSC and not for just one day, but
long-term monitoring, so we can begin to really know the air quality
impacts and human health risks from this foundry. This is the least
that is owed to our community.
Finally, the waste incinerator at PSC is much like the
old trash burners found in most residential backyards of the 1950s. We stopped burning our residential trash long ago. Now,
we must ask why the city of Berkeley allows BAAQMD, or more specifically,
PSC, to burn its trash in the backyards of West Berkeley and Albany.
Shut down the incinerator now!
