S.C. Code § 40-33-41
Upon request on a form provided by the board and payment of the applicable fee, the board shall place a person on the official inactive status if the person is currently licensed under this chapter and does not meet the minimum continued competency requirement for renewal or wishes to retire from practice temporarily. While on inactive status the person is not subject to the payment of any renewal fees and must not practice nursing in this State. To apply for reinstatement, the person shall submit an application, pay a reinstatement fee for the current period, and demonstrate continued competency as defined in regulation. The board may deny reinstatement based on evidence of unlawful acts, incompetence, unprofessional conduct, or other misconduct.
