During each year in which an ad valorem tax is levied on the property with the Greenville-Spartanburg Airport District, the commission of said district shall determine the total amount realized from such tax and notify the treasurer of that county, paying to the Comptroller General less than that turned over to said Comptroller General by the other county. Thereupon such treasurer shall, from the general funds of his county, pay to the treasurer of the other county, to be placed in the general funds, such amount as shall be necessary to equalize the amount contributed by each county.
