Certainly I will try.
When you take a word like “toxic”, it has a tremendous emotional impact on consumers, on the general public, on legislators, on courts, and on customers, and you make it the end goal of a science assessment. Then the entire debate will be around proving whether that substance is toxic or not.
Now, I'm not a linguist or a lawyer, but “toxic” has a meaning in the ordinary sense of the word that just about every citizen will have in their mind when they hear the word: “It's poison. Don't touch this. It's bad. Ban it.” And there are many substances, salt being one of them, ammonia another, that are absolutely essential for life, yet they have externalities; there are situations where they need to be managed. And the application of salt to roads for de-icing is one in which I think most reasonable people would say yes, we need to come up with some management protocols so we can balance the benefits with the potential negative outcomes, come up with the optimal solution. That's what we call a risk management situation, where everyone sits down and they do the best they can to define what appropriate risk management is. They use science to guide them, and they use practicality. They use the real-life issues of whether you're going to use a $10 product or a $100 substitute, and what the cost-benefit ratio is.
But all of the meaningful discussions around mismanagement get taken away because we spent five years debating whether or not you could call salt toxic. It just amazes me that we would spend so much political effort.
Now, many lawyers said you have to do this because of the constitutional question as to who has jurisdiction. If you don't label it “toxic”, then there may not be federal jurisdiction. The unfortunate outcome of the jurisdictional debate as to what was required for jurisdiction meant.... For example, in my own industry, which is an export industry, we export 75% of our production. In the case of potash, we export 95% of it. We almost lost one of our largest offshore markets, Japan, because the Japanese government took a look at our exports of potash and they said “Your government is declaring potassium chloride toxic; therefore, we can't use this substance in our holistic organic food production system”, and we almost lost that market.
These are the consequences of trying to stick an inappropriate label on products, on substances, and this is where the situation ends up when we don't focus on risk management.
I'm sorry, that was very long-winded.
