As you know, weve been following the ongoing Chevron oil leak at the North Burnaby refinery since last spring. Local residents have raised the issue of the MTBE leak at Chevron, which happened years ago. MTBE is an additive to gas that was banned in the U.S. after it started showing up in drinking water all over the country. Chevron in Burnaby used to use MTBE up until 2000, and apparently it had leached into the ground because the tank it was in had a rusted-out bottom.
I was chatting with Judi Marshall about Chevrons history, and she mentioned that the MTBE leak (the stuff that was getting offsite) was discovered by some local high school students in 2001. She sent this story from 10 years ago (keep reading below, there are a couple other posts on the same subject.)
CHEVRON AND CORPORATE IRRESPONSIBILITY
By Murray Dobbin
May 29 2001 Theres a story from British Columbia that warrants exposure across the country because it speaks to the issue of citizenship the flesh and blood kind, the corporate variety and their differences. Lets call this a comparison-shopping column in deference to our dominant cultural paradigm. Which of the following citizens would you choose?
It all started with two high school students, Matthew Clive, 17, and Kevin Kelln, 16, doing a science project for their grade 11 class at North Burnabys Alpha Secondary School. The goal was to determine the effects of the Chevron refinery on the surrounding environment and community. The refinery in question is on Burrard Inlet. When they got the results of their groundwater tests back from the private lab, they discovered the water, taken from north of the refinery, was contaminated by MTBE, a gasoline additive.
They then discovered that MTBE is so potentially dangerous and so persistent once it enters the environment that a CBS 60 Minutes report referred to it as the biggest environmental crisis of the next decade. The United States announced a phase-out plan last year. California has moved even faster to discontinue its use because it has more than its share of the hundreds of public water systems that have been ruined by the stuff. Possible human health problems include cancer, asthma and depression of the central nervous system.
When Mr. Clive and Mr. Kelln revealed their findings to the community, with the help of the Society Promoting Environmental Conservation, Chevron simply denied there was a problem. Their community affairs manager Ray Lord told the media There is nothing operationally here that would indicate any problems. That was on April 8. But Chevron had a different story for the B.C. Ministry of the Environment (ME). Four days earlier they had told ME staff about finding a pool of MTBE-contaminated groundwater on their site with concentrations significantly higher than those found off site.
Matthew says Chevron called him at home and told him he wasnt being helpful. Chevrons manager, Tom Kovar, penned a letter to the companys Community Advisory Panel decrying the unwarranted alarm that was being created.
Stay with me now, dates are important here. Just days after the students revealed their findings, Burnabys Director of Engineering did his own testing of the same sites examined by the students. He found levels three times as high as theirs. He informed Chevron of the test results on April 17, two days before Mr. Kovar wrote his letter.
In the meantime, Burnaby City Council was becoming infuriated with being kept in the dark. At two heated meetings it discovered that the Ministry of the Environment had a verbal agreement with Chevron not to reveal the on-site MTBE contamination to the public or to Burnaby council. It wanted Chevron to have time to get its story straight, something we do all the time admitted ME spokesman Ray Rob. The Ministry, said Mr. Rob, was aware of a plume of contamination covering over 2,500 square feet at a depth of 100 feet. Readings were as high as 2,000 times greater than that found by Burnabys Engineering Department.
But thats not all. The flurry of testing resulting from the students chance findings has now revealed that the plume of MTBE also contains Benzene. And if you think MTBE is bad, benzene is one of the worlds nastiest chemicals. We know it causes lymphoma, leukemia and other blood diseases. Chevrons Ray Lord informed me that Workers Compensation inspectors did an unscheduled examination of the site and were satisfied that workers were not in any danger.
I asked Matthew Clive what he thought about all the commotion he and Kevin had caused. If we hadnt done this, no one would have known. But the thing that concerned me the most was the secret agreement that, as long as all the contamination remained on the [Chevron] property, they wouldnt say anything publicly. Then it was off the site and they still didnt say anything.
Chevron says the off-site levels are barely above the acceptable levels for drinking water. But thats hardly the point. There wasnt supposed to be any MTBE off site. And this sixty-five-year-old refinery is falling apart, with numerous accidents and spills over the past few years. What was Chevron planning to do when it closed down? This is where disasters like the Sydney Tar Ponds get started. Despite this, corporate lobby groups insist that voluntary self-regulation is the way to go. God help us.
One last note. Corporate citizen Chevron is part owner of rights to offshore oil in northern B.C. British Columbians might want to ask how they could trust Chevron with such a delicate operation (if it goes ahead) when we cant even trust them to keep their own site clean or tell the public about contamination?
Maybe we could ask real citizens Matthew and Kevin to keep an eye on them.
And heres a press release from SPEC, the Society Promoting Environmental Conservation.
IMMEDIATE RELEASE: April 05, 2001
Burnaby students find leak of toxic gas additive near Chevron refinery
VANCOUVER- Two grade eleven science students from North Burnabys Alpha Secondary have found toxic methyl tertiary butyl ether (MTBE) gas additive draining into Burrard Inlet from a pipe below Chevrons North Burnaby refinery.
Matthew Clive, 17, and Kevin Kelln, 16, were conducting a science project to determine the effects of the Chevron oil refinery on the surrounding environment and community.
According to their report, Clive and Kelln took samples around the refinery and in adjacent Confederation Park which is designated as a dog park and inhabited by animals. The trail is utilized on a daily basis and many people continue down to the ocean and along the railroad tracks. A sample from a pipe halfway between the refinery and Chevrons nearby tank farm showed a level of 6.9 micrograms/litre of MTBE. Clive and Kelln say that when surveyors went and tested the ground water in California the highest recorded contamination was recorded at 5.6 micrograms/litre.
MTBE is added to gasoline as an octane booster and is notoriously difficult to contain. Even tiny amounts of MTBE can poison water supplies such as happened in Santa Monica, Calif. A 1998 University of California study determined that MTBE is an animal carcinogen with the potential to cau
se cancer in humans. California is phasing out MTBE.
Chevrons North Burnaby refinery is a major MTBE producer. Last May, when 80,000 litres of MTBE leaked from a tank at the refinery, Chevron and Environment Ministry officials assured the material was contained on site. After two workers cleaning up the spill were injured in an explosion a week later, the Environment Minister called for a safety review of the accident plagued refinery. The review is expected to be completed by early 2002.
Whatever the results of the review, Clive and Kelln have reached their own conclusion. The Chevron Refinery in North Burnaby has a negative effect on the community and the environment, the two students say in their report.
Clive and Kelln will release full details of their study at a Science Fair at the UBC Student Union Building on April 6 and 7.
