[Bldg-sim] ASHRAE 62 question

Just going through table 6.4 in ASHRAE 62.1-2007 it looks like the minimum exhaust rates for labs (educational science laboratories) is 1 cfm/ft2. That amounts to an ACH of 6 (for a 10ft ceiling) and 6.7 for a 9ft ceiling.

Am I interpreting that correctly? Does that mean for LEED projects we cannot go below 6 - 7 ACH? Is there a way around it?
