A. Within thirty days of the designation of a subsequent active management area pursuant to article 2 of this chapter, the director shall establish a management goal for the active management area and the number of years in which the goal is to be achieved.

B. Not later than two years after the designation of a subsequent active management area, the director shall promulgate an initial management plan for the active management area and may provide for subsequent management plans to be promulgated during the time set for achieving the management goal. If the director determines that active management is necessary to preserve the existing supply of groundwater for future needs or that land subsidence or fissuring is endangering property or potential groundwater storage capacity, the director, in developing the plan or plans, shall include measures for reducing groundwater withdrawals which follow as closely as practicable the program set forth in sections 45-564 through 45-568. If the director determines that active management is necessary because the use of groundwater is resulting in actual or threatened groundwater quality degradation, the director shall, in cooperation with the department of environmental quality, include in the plan or plans a program for prevention or amelioration of groundwater quality problems and a schedule for implementation of the proposed solutions. The director shall submit such program to the legislature for any necessary enabling legislation or coordination with existing programs of the department of environmental quality.

C. All management plans, including the management goal, for a subsequent active management area, shall be adopted only after public hearings pursuant to sections 45-570 and 45-571.
