Commencing with the third fiscal year following a final adjudication of all or substantially all of the rights to extract ground water and a determination of the natural safe yield of the ground water supplies within the district, and a determination of the amount or extent to which the rights to extract ground water so adjudicated may be exercised without exceeding the natural safe yield of such ground water supplies, the board of such district shall recognize such judicial determination by exempting from replenishment assessments the amount of water pumped by each person whose rights have been so adjudicated which does not exceed his proportionate share of the natural safe yield of the ground water supplies of the district, as so adjudicated from time to time by the court having jurisdiction over such adjudication proceeding. The replenishment assessment shall thenceforth be levied on each producer by multiplying the production in acre-feet of ground water so produced by such producer’s water-producing facility in excess of his said adjudicated share of the natural safe yield by the rate of the replenishment assessment fixed and levied by the board for the fiscal year in which such production shall occur.

Upon such final adjudication, the board may, and within 90 days after receipt of a written notice from a producer shall, by resolution make a determination whether the adjudication will invoke the provisions of this section as of the beginning of the third fiscal year. Such determination is subject at any time to review de novo by any court of competent jurisdiction in any action for declaratory relief, or other appropriate action.
