Green Cleaning in a Fab

I'm working on a semiconductor fab that is part of a LEED campus project. The campus has a well-established, campus-wide green cleaning program in place. Other LEED office projects on this campus have earned an ID credit for green cleaning. The client is committed to this. Cleaning in the fab is limited to packaged lint-free wipes pre-soaked in ultra pure water (UPW), some with very dilute iso-propyl alcohol (IPA). No other chemicals are used. Management is considering eliminating these dilute IPA wipes and using just UPW wipes. Questions: (1) what is the consensus on whether dilute IPA wipes align/don't align with green cleaning protocol? (2) Are there any potential barriers that this fab could expect in pursuing the ID credit for green cleaning? Thanks. David
