In the event the assistant secretary shall have authorized use of water as provided herein, he shall annually thereafter, and so long as such use continues, review the use of such water in order to determine if such continued use will be detrimental to the water supply of the area from which the water is being extracted. Further, if the local governing body of the parish from which the water is being extracted shall make a formal motion to the assistant secretary suggesting that continued use of such water will be detrimental to the water supply of the area from which the water is being extracted, then in that event the assistant secretary shall immediately call a public hearing to determine whether such continued use will be detrimental to the water supply of such area.
