S.C. Code Ann. § 31-22-30
(B) A local government that creates an LHTF or RHTF may finance the LHTF or RHTF with money available to the local government through its budgeting authority unless expressly prohibited by the law of this State. Sources of these funds include, but are not limited to, one or more of the following:
(3) grants and loans from a state, federal, or private source.
The local government may alter a source of funding for the LHTF or RHTF by amending the ordinance that establishes financing for the LHTF or RHTF, but only if sufficient funds exist to cover the projected debts or expenditures authorized by the LHTF or RHTF in its budget. This chapter does not create, grant, or confer a new or additional tax or revenue authority to a local government or political subdivision of the State unless otherwise provided by the law of this State.
