Is there a difference? :)
I'm basing it on the fact the last we were told, more than 6 months ago, was that all requested information had been provided to the EPA. According to what we were lead to believe EPA approval was a given (in fact we were orginally told it wasn't even needed, iirc). It is now many moons later and still no approval - why not? As far as we know the EPA hasn't requested any additional testing/data so the longer this goes on, it seems to me, the less chance of approval.
