re: closed loop (and/or) zero discharge systems
this has been an area of controversy, disagreement, speculation and hopeful
anticipation longer than I can recall. They're also areas that regulators
seem to shy away from resolving... probably from fear that the resolution
would be even more unreasonable than what we're stuck with currently.
I feel strongly these are areas where a creative and sommon sense look at the
problem and the regs could produce some very beneficial solutions, both in
terms of simplification and environmental benefit. Sounds to me like a
Project XL challenge... any takers??
