S.C. Code Ann. § 44-2-60
(A) The owner or operator of an underground storage tank which stores or is intended to store a regulated substance shall register the tank with the department. The owner or operator of the tank shall display a registration certificate listing all registered tanks at a facility and in plain view in the office or the kiosk of the facility where the tanks are registered. Upon application for a registration certificate, the owner or operator shall pay to the department an initial registration fee of one hundred dollars a tank; however, the department may prorate the initial registration fees on a daily basis for underground storage tanks installed on or after July 1, 1997. The owner or operator shall pay to the department an annual renewal fee of one hundred dollars a tank a year. No person may place a regulated substance and no owner or operator may cause a regulated substance to be placed into an underground storage tank for which the owner or operator does not hold a currently valid registration. The department may not issue a registration certificate until all past and present fees and penalties owed on a tank are paid. The department may not issue a registration certificate to any owner or operator who has not complied with all terms of a consent or final administrative order issued under Section 44-2-140.
All fees are due to the department within thirty days of billing. The department shall issue a late notice, with no penalty due, to an underground storage tank owner or operator who has unpaid fees thirty days after billing. An owner or operator who fails to pay the fees within sixty days of the initial billing must pay a ten percent penalty in addition to the ten percent penalty for any fees remaining unpaid ninety days after the initial billing. An owner or operator with unpaid fees ninety days after the initial billing is subject to additional enforcement action as provided for in Section 44-2-140.
The department may not disburse Superb Account or Superb Financial Fund monies to any person or persons for the rehabilitation of a petroleum or petroleum product release from any underground storage tank or underground storage tank system where all past and present fees and penalties owed on the applicable tank have not been paid.
The funds generated by the registration and late penalty fees may be used by the department for administration of the provisions of this chapter and for administration of the underground storage tank regulatory program established by this chapter. The amount used for administration may not exceed three million dollars a year.
