When determining compliance Schedules, how is a system's population served determined?  Are system populations based on the wholesale system's population or the sum of the wholesale system's population and the purchased systems' population?

Each system should individually determine its population served and then determine if it is part of a combined distribution system (CDS).  The retail population of the largest system in the CDS would determine the Schedule for the CDS, with the exception of systems that buy but do not sell finished water to another system.  These systems determine their compliance Schedules based on their own retail population served.
