Description
The Swan Hills rotary kiln (15) incinerators have for many years been Canada's only permanent facility for the disposal of high-level PCB waste. In 1998, more PCB waste was incinerated than in any previous year.(16) Annual capacity is for 53 000 tonnes of hazardous wastes.(9) Here is a chronology of recent events:

On October 16, 1996, a mechanical failure to one incinerator caused a major release of PCBs and dioxin,(2) resulting in the laying of six charges by the Alberta government.(17)

On December 13, 1996, the Provincial Health Officer issued a health advisory against eating wild game from within a 30 km radius of the plant,(18) and during the same month, Environment Canada advised federal departments against sending hazardous waste to Swan Hills (19)(advice withdrawn in 1999(13)).

On July 21, 1997, an explosion in the other incinerator forced it to be shut down as well,(17) and the Alberta government warned that PCBs and dioxin may have been released.(20)

On August 26, 1997, Professor David Schindler of the University of Alberta released a report which concluded the Swan Hills incinerators had been contaminating the region with PCBs and dioxin for years prior to these accidents.(21)

On October 22, 1998, Bovar was fined $625 000, the highest environmental penalty ever imposed in Alberta, as a result of the 1996 charges.(13,22)

Currently, only the larger incinerator is operating, the smaller one having been shut indefinitely in March 1998.(23) Other hazards associated with the facility include a disposal well for liquid waste and a landfill for incinerator ash,(24) found to be leaking in 1992;(9) and the ongoing threat from forest fires, which forced two evacuations of the town of Swan Hills in May 1998.(25)


Action
PCBs and other chlorinated POPs must be eliminated from the environment, as called for by the Toxic Substances Management Policies adopted by the federal government and the Canadian Council of Ministers of the Environment (CCME). Destruction of PCB stockpiles should be carried out as soon as possible by a processes which avoid the fundamental flaws of incineration (see above). Such non-incineration destruction projects must have:

Effectively 100% destruction efficiency;

Complete containment of all residues;

No uncontrolled releases;

Full involvement by all affected communities;

A clearly delimited time period of operation.

The federal and/or Alberta governments should take urgent measures to stop the burning of POPs and other chlorinated wastes at Swan Hills.
