S.C. Code § 13-21-90
No bonds may be issued pursuant to the provisions of this chapter until the proposal of the board of the authority to issue the bonds receives the approval of the State Fiscal Accountability Authority. When the board proposes to issue bonds, it shall file a proposal with the State Fiscal Accountability Authority or the Department of Administration, as appropriate, setting forth:
Upon the filing of the proposal, the State Fiscal Accountability Authority or the Department of Administration, as applicable, shall, as soon as practicable, make an independent investigation, as it considers necessary or appropriate, and if it finds that the project is intended to promote the purposes of this chapter, it may approve the project. At any time following the approval, the board may proceed with the acquisition and financing of the project. If the proceeds of the bonds are to be made available to a company to construct a project, as provided in Section 13-21-50, notice of the approval of any project by the State Fiscal Accountability Authority or the Department of Administration, as applicable, must be published at least once by the authority in a newspaper having general circulation in the county where the project is to be located.
Any interested party may, within twenty days after the date of the publication notice, but not after the twenty days, challenge the validity of the approval in the court of common pleas in the county where the project is to be located.
