(1) When the Governing Board determines that regional action is necessary to address cumulative water withdrawals that are causing or may cause adverse impacts to the water and related natural resources or the public interest, it shall declare, delineate, or modify Water Use Caution Areas (WUCAs). The Governing Board shall declare a WUCA by adopting a rule or issuing an order imposing special requirements for existing water users and permit applicants to prevent or remedy impacts to water and related natural resources or the public interest.
    (2) In determining whether an area should be declared a WUCA, the Governing Board shall consider the following factors:
    (a) The quantity of water available for use from groundwater sources, surface water sources, or both.
    (b) The quality of water available for use from groundwater sources, surface water sources, or both, including impacts such as saline water intrusion, mineralized water upconing, or pollution.
    (c) Environmental systems, such as wetlands, lakes, streams, estuaries, fish and wildlife, or other natural resources.
    (d) Lake stages or surface water rates of flow.
    (e) Offsite land uses.
    (f) Other resources as deemed appropriate by the Governing Board.
    (3) The regions described in this rule have been declared WUCAs by the District Governing Board. This rule reaffirms the declaration of WUCAs and creates conditions to be applied to water users in those areas.
    (a) Northern Tampa Bay Water Use Caution Area.
To address groundwater withdrawals that have resulted in lowering of lake levels, destruction or deterioration of wetlands, reduction in streamflow and salt water intrusion, the Governing Board declared portions of northern Hillsborough County, southwestern Pasco County and all of Pinellas County a WUCA on June 28, 1989, pursuant to Resolution Number 934. The Governing Board approved expansion of the boundaries of the WUCA in June 2007.

    b. Quantities of 100,000 gpd annual average or greater from groundwater when at least one withdrawal point is within the Dover/Plant City WUCA.
    c. A permit with at least one withdrawal point within the Dover/Plant City WUCA for groundwater quantities to provide frost/freeze quantities authorized to be used or withdrawn from any combination of sources that if withdrawn from groundwater alone would have the potential to impact the Minimum Aquifer Level Protection Zone established for the Dover/Plant City WUCA.
    d. A permit with at least one withdrawal point within the Dover/Plant City WUCA for groundwater quantities to provide supplemental irrigation for a use that typically requires frost/freeze protection and where such protection could be achieved through groundwater withdrawals but alternative protection methods are proposed.

Permits with permitted withdrawals in more than one WUCA shall be subject to the conservation and reporting requirements, if any, of the WUCA within which the majority of permitted quantities are withdrawn, or projected to be withdrawn, in addition to all other rule criteria, including MFL requirements, as set forth in Fl.
