S.C. Code Regs. § § 103-532.5
The utility shall provide for the arrangement of a deferred payment plan to enable a residential customer to make payment by installments where such customer is unable to pay the amount due for service. The deferred payment plan shall require the affected customer to maintain the customer's account current and pay not less than 1/6 of the outstanding balance for a period not to exceed six months. The outstanding balance may include the late payment charge authorized by R.103-532.2. Service to such customer shall not be terminated unless the utility has informed the customer that such deferred payment plan is available. A deferred payment plan is any agreement to extend or defer a payment cut-off date by more than 5 work days. If a customer fails to conform to the terms and conditions of such deferred payment plan, the utility may terminate service upon fifteen days written notice, with copies of such termination notice mailed to DHEC and the ORS.
