The Department shall, from funds appropriated for this purpose, reimburse schools which have undertaken corrective action. Such schools, upon completion of an inspection by the Department, shall be eligible for reimbursement only for those projects found to have been conducted in accordance with the provisions of this Act and the rules promulgated thereunder. Schools shall apply for such reimbursement to the Department on forms designed and provided by the Department.
The amount of reimbursement for which a public school district is eligible shall be calculated by the Department based upon a Grant Index developed by the State Board of Education. This Grant Index shall be based upon the equalized assessed valuation of the school district and other measures of relative wealth to determine the percentage of the total cost of corrective action for which reimbursement shall be authorized. The Grant Index for any school district is equal to one minus the ratio of the district's equalized assessed valuation per pupil in weighted daily average attendance to the equalized assessed valuation per pupil in weighted average daily attendance of the district located at the ninetieth percentile for all districts of the same type. The Grant Index for any school district shall be not less than .50 and no greater than 1.00. The product of the district's Grant Index and the project cost, as determined by the Department for approved corrective action, equals the total amount that shall be reimbursed to the school according to the provisions of this Section. All non-public schools shall be eligible for reimbursement in an amount equal to 50% of the cost of corrective action.
Out of funds appropriated for such purpose, 20% of the amount of reimbursement to which any school is determined entitled shall be paid in each of 5 successive fiscal years. The Department shall request an annual appropriation in an amount sufficient to cover all expected reimbursements to be paid out in that fiscal year.
For purposes of reimbursement under this Section, corrective action means removal, encapsulation or enclosure. Schools reimbursed pursuant to this Section for corrective action shall not be eligible for grants under Section 9b with respect to the corrective action for which they are so reimbursed.
