A. In an initial active management area, a person who owns land which was legally entitled to be irrigated with groundwater and who retired such land from irrigation after January 1, 1965 but prior to the date of the designation of the active management area in anticipation of a non-irrigation use has the right to withdraw from or receive for such land three acre-feet of groundwater per acre per year upon showing that:
1. The land has been held under the same ownership since it was retired.
2. A development plan for the proposed non-irrigation use existed at the time the land was retired.
B. In a subsequent active management area, a person who owns land which was legally entitled to be irrigated with groundwater and retires such land from irrigation prior to the date of the designation of the active management area in anticipation of a non-irrigation use has the right to withdraw from or receive for such land the lesser of three acre-feet of groundwater per acre per year or the average annual amount of groundwater which was used per acre during the five years preceding the time the land was retired upon showing that:
1. The land has been held under the same ownership since it was retired.
2. A development plan for the proposed non-irrigation use existed at the time the land was retired and is filed with the director within ninety days after the active management area is designated.
C. The development plan requirements of this section are deemed fulfilled if the land retired from irrigation has been described in an application for a certificate of exemption or if the land retired from irrigation is owned in conjunction with non-irrigation uses existing or for which substantial capital commitments have been incurred for the non-irrigation development of such land as of the date of the designation of the active management area.
D. The right to withdraw or receive groundwater pursuant to this section is a non-irrigation grandfathered right associated with retired irrigated land, or a type 1 non-irrigation grandfathered right.
E. A type 1 non-irrigation grandfathered right is appurtenant to the acre of retired irrigated land associated with the right, is owned by the owner of the land to which the right is appurtenant and may be leased with the land.
F. At the request of a city or town in the Tucson active management area that holds a type 1 non-irrigation grandfathered right under subsection A of this section, the director, in determining whether to designate or redesignate the city or town as having an assured water supply pursuant to section 45-576, shall include four and one-half acre-feet of groundwater for each acre of retired irrigated land to which the right is appurtenant, multiplied by the number of years between the year of retirement and the year of the request, minus the quantity of groundwater withdrawn from the land between June 12, 1980 and the year of the request, except that:
1. No groundwater may be included for any acre of retired irrigated land for any year after the land is developed for any municipal or industrial use.
2. The amount of groundwater that is included under this subsection shall not exceed four and one-half acre-feet for each acre of retired irrigated land to which the right is appurtenant multiplied by the number of years between the year of retirement and December 31, 2025 minus the quantity of groundwater withdrawn from the land between June 12, 1980 and December 31, 2025.
3. The net amount of groundwater included under this subsection shall not exceed two million acre-feet.
4. The city or town, before making the request of the director, shall extinguish any irrigation grandfathered rights or type 1 non-irrigation grandfathered rights held by the city or town and appurtenant to land acquired or contracted for by the city or town after June 12, 1980 in the same sub-basin.
