If the total eligible amounts claimed for conservation project financial assistance, as approved by the committee and the department, exceed the appropriation after reimbursements have been made therefor, each district would be awarded a pro rata amount equivalent to the percentage arrived at by dividing the appropriation by the total eligible amount. For example, if the total eligible amount is $120,000 and the appropriation is $80,000, each district would receive two thirds of the amount it would be otherwise eligible for.
