Budgeted expenditure adjustments may be made by increasing an approved activity-object expenditure amount for school districts and a budgeted line item for all other summer food service program sponsors by up to ten percent and decreasing others without filing a request for a budget revision with the superintendent of public instruction. These adjustments may be made only once for each grant and only if the increases, in total do not exceed ten percent of the total budgeted expenditures and do not increase total budgeted expenditures.
