COLUMBIA, S.C. -- South Carolina’s economic advisers say the state lottery is generating more profits than expected, allowing legislators to designate more money to school buses, libraries and scholarships.

The Board of Economic Advisors revised its estimates Wednesday for lottery revenue. Advisers expects an additional $27 million to be collected this fiscal year and an extra $7 million in the year that starts July 1.

State law limits lottery profits to college scholarships, public libraries and some kindergarten-through-12th-grade programs, including transportation.

State Superintendent Mick Zais has asked legislators throughout the budget process to put more money toward purchasing new school buses.

The board’s revised estimate comes a week before senators debate its budget plan for 2013-14 on the chamber floor.

Advisers did not alter their earlier estimates from other revenue sources.
