The Section of the prerequisite language that is referenced by IRC 1504 is the below, you don’t need to know any more than that.

“For exhaust hood systems capable of exhausting in excess of 400 cubic feet per minute (188 liters per second), provide makeup air at a rate approximately equal to the exhaust air rate. Makeup air systems must have a means of closure and be automatically controlled to start and operate simultaneously with the exhaust system.”

It should be 1503.4. USGBC says they're getting that fixed.
