Great.
I had one question with respect to the domestic substances list you mentioned. You also mentioned that substances in use in the 1980s and so forth were actually required to be reclassified, which I understand from talking to some industy officials was a fairly painful process for some of them. My question pertains to the use of the word “toxic”, and how we're attributing “toxic” to certain substances, and in fact how that may be misconstrued. Is there another term we could be using in classifying substances, a term that might not be as misleading and potentially damaging in referring to substances that may be toxic in given uses, but are not inherently toxic by nature, such as carbon dioxide?
