COLUMBIA — South Carolina’s schools would get an additional $105 million to head off teacher furloughs under a spending proposal the Senate will debate.

Wednesday’s debate of the $6 billion spending plan comes after the state’s revenue forecasting board last week added $210 million to budget estimates.

Senate Finance Committee Chairman Hugh Leatherman of Florence said Tuesday that $105 million should be added to school budgets. Leatherman says that will head off tax increases for businesses as schools try to find cash for their budgets.

The proposal faces opposition from lawmakers who want the money used as a taxpayer rebate or to reduce state debt.
