RESTRICTIONS ON PRODUCTION DURING EXTREME DROUGHT.

(a) During a period declared by the district to be an extreme drought, to maintain groundwater production necessary to sustain human consumption and protect the public's health, safety, and welfare, the district, as provided by this section, may impose greater restrictions on groundwater production for industrial, commercial, or nonagricultural irrigation permits than the district imposes on permits for other uses.

(b) For an industrial, commercial, or nonagricultural irrigation permit first issued on or before September 9, 2004, the district may restrict withdrawals by an amount not to exceed 40 percent of the amount permitted on or before September 9, 2004, retaining at least 60 percent of the total authorized pumpage, if:

(1) an alternative water supply for at least 10 percent of the amount permitted is available and in place during the extreme drought; and

(2) any restriction imposed by the district under Sections 8802.109(b) and (c) remains in effect.

(c) For industrial, commercial, and nonagricultural irrigation permits first issued on or before September 9, 2004, and amended after September 9, 2004, the district may impose greater restrictions, including complete curtailment, for the additional amount of water authorized by the amendment than the district imposes on similarly situated permittees for other uses.
