Ok Tedi Environmental Disaster

Ok Tedi tailings in the Fly River

The Ok Tedi Environmental Disaster is a term used to describe the ongoing effect of mining on the environment near the Ok Tedi River in Papua New Guinea, particularly the dumping of tailings into the river itself. Although this has been occurring for over two decades, since the beginning of copper mining operations at Ok Tedi Mine, the world's view has been on this particular event recently, due to class action litigation brought upon Ok Tedi Mining Limited and BHP Billiton by local landowners, particularly villagers downstream from Ok Tedi in the Fly River system, particularly in the Middle Fly District and the southern and central areas of the North Fly District who believe the effect on their livelihood from this disaster far outweighs the benefits they have received from the mine's presence in their area. BHP has since dissolved its 52% ownership in the mining company, OTML.

[edit] Environmental impact

In 1999, BHP's CEO, Paul Anderson admitted that the Ok Tedi Mine was "not compatible with our environmental values." The Asia Times interpreted this as an admission of "major environmental damage."^[1] The mine operators discharge 80 million tons of tailings, overburden and mine-induced erosion into the river system each year.^[2] The discharge caused widespread and diverse harm, both environmentally and socially, to the 50,000 people who live in the 120 villages downstream of the mine.^[3] Chemicals from the tailings killed or contaminate fish, however they are still edible by the people of the surrounding villages. The fish count does lower the closer to the mine. The dumping changed the riverbed, causing a relatively deep and slow river to become shallower and develop rapids thereby disrupting indigenous transportation routes. Flooding caused by the raised riverbed, left a thick layer of contaminated mud on the flood plain among plantations of taro, bananas and sago palm that are the staples of the local diet. About 1300 square kilometers were damaged in this way. Although the concentration of copper in the water is about 30 times above the standard level, it is still below the World Health Organisation (WHO) standards.

The reasons for this disaster are complex. The original plans included an Environmental Impact Statement (done by an Australian Consultancy) that called for a tailings dam to be built near the mine. This would allow heavy metals and solid particles to settle, before releasing the clean ‘high-water’ into the river system where remaining contaminants would be diluted. But the plan was seriously flawed and in 1984 an earthquake (common in the area) caused the half built dam to collapse. Afterwards the company continued operations without any dam, initially because BHP argued that it would be too expensive to rebuild it. Subsequently, the cash-strapped PNG government decided a dam wasn’t necessary, in the wake of the closure of the Panguna mine.

But the seeds of conflict were sown before the mine even begun operations. Almost all of PNG’s land is held under a complex system of native title, with ownership divided amongst a huge number of small clans, while the central government retains control over how resources that lie under the ground are used. The 2000 members of the clan that held ownership of the land on which the mine would be built were included in the formal negotiations. They received money, jobs, vocational training, and infrastructure (schools, health services, etc.). The indigenous communities who live downstream from the mine, however, were not consulted and received none of the benefits.

[edit] Aftermath

In the 1990s the communities of the lower Fly Region, including the Yonggom people,^[4] sued BHP and received US$28.6 million in an out-of-court settlement, which was the culmination of an enormous public-relations campaign against the company by environmental groups. As part of the settlement a (limited) dredging operation was put in place and efforts were made to rehabilitate the site around the mine. However the mine is still in operation and waste continues to flow into the river system. BHP was granted legal indemnity from future mine related damages.

In January 2007 PNG lawyer Camillus Narokobi lodged a lawsuit on behalf of 13,000 villagers known as the Ningerum people. He is seeking $US 4 billion in damages.^[5]

The Ok Tedi Mine is scheduled to close in 2012. Until that time two thirds of the profits go into a long-term fund to enable the mine to continue to contribute to the PNG economy for up to half a century after it closes. The balance is allocated to current development programs in the local area (Western Province) and PNG more generally. Experts have predicted that it will take 300 years to clean up the toxic contamination.^[5]

According to the owners of the Ok Tedi Mine, there have also been many positive social effects that have come from the mine. Because of all the new money pouring into the economy, the quality of the health care, schools and roads has greatly improved. This has also caused the average life expectancy for the indigenous people to increase.^[2]
