Thank you very much, Mr. Chair.
I have just one point of clarification. The risk assessment treated road salts as a kind of mixture, understanding that there were different chloride compounds included in the product, and did an assessment on that whole mixture, which did of course include potassium chloride. It was a very thorough science-based assessment; it was peer-reviewed and internationally leading. The main issue it addressed was whether the amounts used were causing concentrations sufficient in the environment to have adverse effects, and it did come to a conclusion on that.
