Sure. Currently in Canada, spill-treating agents would be considered unlawful, although the evidence base is demonstrated, I think, from a number of incidents around the world, most notably in the gulf, that spill-treating agents did have a net environmental positive benefit. It's a determination that has to be made very far in advance of any incident and done in a way that's, if you will, a mitigating planned sense.
The first step is that the Minister of the Environment would need to designate specific agents as acceptable and would have to do so in regulation. The next step would be that a company would have to develop an emergency response plan and outline the specific circumstances when they would expect to use the agent and what they would expect the behaviour and the response to be. That has to be registered with the board. The board would have to approve that plan and the agents. Then in the event of an incident, the board would have to provide the conservation officer the ability to authorize the use of the agents, given the circumstances that were pre-described were present, whether it was of such a nature, at such a time, and such environmental conditions.
