Let me give you an example.
Road salt has been identified as and deemed to be CEPA toxic. As a result, it has been designated to be put on schedule 1. One of the things you look at is the condition under which road salt can be used. Under CEPA, there is an environmental component and there is a human health component. Certainly when you get road salt close to a freshwater environment and make it saline, that is going to be injurious to the freshwater environment and those animals occupying it, where it may not be injurious to human health. So what we have in the opportunity around the Canadian Environmental Protection Act and the risk assessment that is founded in regulation is that it puts in place, with the knowledge from science of where it is a risk, management strategies that industry is obligated to adhere to in order to minimize the risk that it will get put into, in this case, a freshwater environment.
