S.C. Code § 12-28-930
Each purchaser who desires to make an election under Section 12-28-925 shall present evidence to the department that the applicant was a licensee in good standing under the predecessor motor fuel statute as to which he remitted user fees to the department, or the applicant meets the financial responsibility and bonding requirements imposed by this chapter which bond shall conform to the specific requirements of this section. The department may require a purchaser who pays the user fee to a supplier to file with the department a surety bond payable to the State, upon which the purchaser is the obligor or other financial security, in an amount satisfactory to the department. The department may require that the bond indemnify the department against uncollectible user fee credits claimed by the supplier under Section 12-28-940.
