IEQc5 requirements eased up

"the vague hazardous chemical containment requirement has been removed." This is a layover from LEED v2.0. Rob Watson actually had a lot, if not everything, to do with this. I know this because I understand what is, or was, required. I documented this for the NRDC's Robert Redford Platinum Blond LEED project. You were supposed to plumb sinks that might use hazardous chemicals in a way to prevent the chemicals from being dumped into the sewer lines without being treated first. We tried implementing into the Platinum Blond project's janitorial sink, just to be sure all the LEED requirements were met. AND: "Separate plumbing no longer waived". This is part of the above requirement. The two are in regards to the same issues.
