The program manager shall monitor contributions so as to prevent contributions to any account for a designated beneficiary when such contribution would cause the amount of money in such account to exceed this amount. Any amount tendered as a contribution, or portion of a contribution, that if accepted as a contribution would cause the amount in any account to exceed this amount, shall be rejected as a contribution and shall be returned to the contributor.
