Has anyone received a review comment saying that the shuttle buses must be available during periodic times throughout the day, in addition to most frequent commuting hours?

Our project has a shuttle bus taking occupants to mass transit stations approximately 6 hours of the day during peak commuting periods. We received a comment that we also need to show a shuttle showing periodic service. The above reference guide comment about requirements for shuttle buses and the LEED addendum published 4/1/12, there is no mention of requiring service during periodic hours.

I am wondering where this came from. Does anyone know? If it's in a LEED Interpretation, do you think it's possible to make an argument that this is not posted in the reference guide or LEED addenda therefore we should not be subject to the requirements?

Thank you.
