Concerned citizens from around the world have sent petitions, postcards,
and letters to Mistubishi to express opposition to its plans to build an
industrial salt works next to Laguna San Ignacio, the last undisturbed
nursery ground in Baja California, Mexico for the gray whale.
In response, Motohiki Numaguchi, President of the Mitsubishi
International Corporation, has sent out a form letter which is dismissive
of concerns about the project and its impacts on the whales and the rest
of the extraordinarily fragile ecosystem.
The following is a response, prepared by Dr. Mark Spalding, a Research
Fellow at the Center for U.S.-Mexican Studies of the University of
California, San Diego. He may be contacted at email@example.com:
The project as proposed would utilize barren salt flats located
inland and to the north and west of San Ignacio Lagoon. The flats are not
frequented by any of the region's animal species and are devoid of
The permanent flooding of 116 square miles of coastal tidal flats may
interfere with migratory paths of animals. The planned inundation and
dike system may redirect natural tidal flooding to disturb areas which
are the habitat for numerous marine and terrestrial plant and animal
species. Ponds with highly concentrated salt and waste products also
pose a significant risk of contamination of the lagoon and surrounding
mangroves - a danger that does not currently exist.
The proposed San Ignacio project is specifically designed to protect
the gray whale and the lagoon ecosystem as a whole.
Mitsubishi and its Mexican government partner in its joint venture
called ESSA did not pay sufficient attention to the environmental
impacts from the proposal salt works until they came under pressure from
Mexican and U.S. environmentalists and Mexican environmental officials.
Mitsubishi's first environmental assessment submitted in 1994 did
not even address the potential risks to the gray whale and asserted
there would be little or no adverse effects on other species and natural
In March 1995, the Mexican environmental authorities rejected the salt
works project. The proposal was determined to be incompatible with the
protected status of the area - which is both a World Heritage Site and
part of the Vizcaíno Biosphere Reserve - and an unacceptable risk
to the reserve's natural values, including habitat for the
endangered pronghorn antelope and more than 70 over animal species.
As proposed today, the project is still incompatible. But in June
1995, the Mexican environmental ministry relented and agreed to allow
Mitsubishi to submit a new environmental assessment. This review will be
subjected to a public process and to new terms of reference developed by
an international scientific advisory committee.
In July 1997, Mitsubishi officials first revealed that they have made
some design changes in the project - changes now mentioned in their form
letter - to address the concerns raised by numerous environmental
organizations and experts.
The salt loading pier would be built in an area of prime lobster and
The pier would be regularly visited by large salt transport vessels
and by oil tankers. The pier and ship traffic will occur in the aptly
named Bahia de las Ballenas (Whale Bay) through which the gray whales
regularly pass while in the waters of the Baja Peninsula. This creates a
risk of accidental spillage and collision which does not currently exist
in this area.
Mitsubishi plans to move the 17 large diesel pumps further away from
areas of the lagoon used by the whales, but the pumps will be a one-way
path. Any life that passes through to the salt evaporation ponds will
not be returned to the lagoon. And some of it will perish as the sea
water moves to ponds with higher concentrations of salt.
ESSA's experience of over forty years at a similar facility
just up the Baja coast indicates that the activities of an inland salt
evaporation project are highly compatible with whales and other marine
species. When ESSA first began exporting salt from Baja in 1957, fewer
than 100 gray whales visited the lagoon near its facility. This year, more
than 1,500 whales visited that lagoon - a record number.
We are aware of the steady increase in the counts of gray whales in
the larger, deeper lagoon where Mitsubishi's existing salt works is
located. This cannot be attributed to the presence of the salt works. It
is due to the recovery of the gray whale over the last three decades
since the end of their commercial slaughter. In the late 1950s, there
were less that 1,000 gray whales left; today there are over 22,000.
Japan and some other nations would like to overturn the current
international ban on whaling.
Gray whales are sensitive to noise and human disturbance. From 1957 to
1967, grays were rarely observed using the smaller of the two lagoons
near the existing salt works where the company had barge operations and
had to dredge the mouth of the lagoon. While scientists agree that it is
not possible to establish the bases for whale behavior, it is
interesting to note that the gray whales in Laguna San Ignacio have been
observed to be much more friendly to humans than those in
the three other much more developed and less pristine Baja lagoons
frequented each winter by the grays.
The environmental impacts of ESSA's existing salt works at
Guerrero Negro have only been formally reviewed once in its 40 year
history. According to ESSA's own admission, numerous violations
were found during a government audit in 1995 and the salt works must
comply with orders from Mexico's Attorney General for the
Environment (PROFEPA) to correct those discrepancies. Aside from the
direct impacts, the creation of the salt works there led to a swelling
of Guerrero Negro's population from less than 100 forty years ago
to some 10,000 today. In January 1998, the local fisherman complained
that toxic releases from the salt works were responsible for the deaths
of a hundred or more endangered sea turtles.
ESSA is commissioning an independent study of the proposed project
involving some of the world's most prestigious scientists, and is
making the results publicly available.
ESSA is required by Mexican law to prepare an environmental impact
study of the proposed project and to make the results public. Like
environmental reviews in the United States, the study is being prepared
by contractors. The Mexican Environmental Ministry deserves credit for
insisting that this study be subjected to an unprecedented review by the
international scientific review committee before any final decision is
made on the project.
The Bottom Line
We can be pleased that Mitsubishi has been forced to listen to your
concerns. Our efforts have contributed to improvements in the project and
a much higher level of environmental scrutiny, but the project would still
- have a massive footprint -- almost twice the size of Washington, D.C.
- disturb and degrade a unique and irreplaceable natural area that
supposedly has the protection of the Mexican Government as part of the
Vizcaino Biosphere Reserve and the recognition of the United Nations as
a World Heritage Site, and
- pose risks of direct and indirect harm to the whales, numerous other
species, and related natural systems, including those associated with
the expected influx over time of additional people and exploitative
activities in a very fragile desert environment.
