The telephone assistance fund is created as a separate account in the state treasury to consist of amounts received by the commissioner of public safety representing the surcharge authorized by section 237.70, subdivision 6, and amounts earned on the fund assets. Money in the fund may be used only for:
(1) reimbursement to local service providers for expenses and credits allowed in section 237.70, subdivision 7, paragraph (d), clause (5);
(2) reimbursement of the reasonable administrative expenses of the commission, a portion of which may be used for periodic promotional activities, including, but not limited to, radio or newspaper advertisements, to inform eligible households of the availability of the telephone assistance program;
(3) reimbursement of the statewide indirect cost of the commission; and
(4) reimbursement of the reasonable expenses of the commissioner of commerce and the commissioner of human services for administering section 216C.266, subdivisions 2 and 4.
