A work activities center program (WAC) shall be a physically separated unit of the workshop, having an identifiable program, separate supervision and records, planned and designed exclusively to provide therapeutic activities for handicapped workers whose physical or mental impairment is so severe as to make their productive capacity inconsequential. Therapeutic activities include custodial activities (such as activities where the focus is on teaching the basic skills of living), and any purposeful activity so long as work or production is not the main purpose.
