" In lieu water"  means water that is delivered by a storer to a groundwater savings facility pursuant to permits issued under this chapter and that is used in an active management area or an irrigation non-expansion area by the recipient on a gallon-for-gallon substitute basis for groundwater that otherwise would have been pumped from within that active management area or irrigation non-expansion area.

23. " Water that cannot reasonably be used directly"  means water that the storer cannot reasonably put to a direct use during the calendar year,  including:
(a) Except as provided in subdivision (b) or except for an agricultural improvement district as provided in subdivision (d),  if the storer is a municipal provider,  the amount of central Arizona project water that exceeds the amount of mined groundwater withdrawn during the calendar year by the storer in the active management area in which the storer's service area is located. If the storer withdrew mined groundwater during a calendar year in which the storer stored central Arizona project water underground pursuant to the storage permit,  the amount of central Arizona project water stored underground during that year equal to the amount of mined groundwater withdrawn from the active management area in which the storer's service area is located shall not be credited to the storer's long-term storage account but may be considered as being available for recovery by the storer on an annual basis under section 45-851.01. In calculating the amount of mined groundwater withdrawn by the storer from the active management area,  the director,  at the request of the storer,  shall exclude any groundwater withdrawn,  treated and delivered for direct use as part of a remedial action undertaken pursuant to CERCLA or title 49,  chapter 2,  article 5. For the purposes of this subdivision,  " mined groundwater"  and " municipal provider"  have the same meanings prescribed in section 45-561.
(b) If the storer is a municipal provider that has been designated as having an assured water supply pursuant to section 45-576,  the amount of central Arizona project water that exceeds the amount of deficit groundwater withdrawn during the calendar year by the storer in the active management area in which the storer's service area is located. If the storer withdrew deficit groundwater during a calendar year in which the storer stored central Arizona project water underground pursuant to the storage permit,  the amount of the central Arizona project water stored underground during that year equal to the amount of deficit groundwater withdrawn from the active management area in which the storer's service area is located shall not be credited to the storer's long-term storage account but may be considered as being available for recovery by the storer on an annual basis pursuant to section 45-851.01. In calculating the amount of deficit groundwater withdrawn by the storer from the active management area,  the director,  at the request of the storer,  shall exclude any groundwater withdrawn,  treated and delivered for direct use as part of a remedial action undertaken pursuant to CERCLA or title 49,  chapter 2,  article 5. For the purposes of this subdivision,  " municipal provider"  has the same meaning prescribed in section 45-561 and " deficit groundwater"  means that amount of groundwater withdrawn within an active management area for delivery and use within a service area by a municipal provider in excess of the amount of groundwater that may be withdrawn by the municipal provider consistent with the achievement of the active management area's management goals as prescribed by rules adopted by the director pursuant to section 45-576.
(c) Except as provided in subdivision (d),  if the storer is not a municipal provider,  the amount of central Arizona project water stored in an active management area that exceeds the amount of groundwater withdrawn during the calendar year by the storer in that active management area. If the storer withdrew groundwater in an active management area during a calendar year in which the storer stored central Arizona project water underground in that active management area pursuant to the storage permit,  the amount of central Arizona project water stored underground during that year equal to the amount of groundwater withdrawn from the active management area shall not be credited to the storer's long-term storage account but may be considered as being available for recovery by the storer on an annual basis under section 45-851.01. For the purposes of this subdivision,  " municipal provider"  has the same meaning prescribed in section 45-561.

(ii) The amount of groundwater withdrawn by the storer during the year for mineral extraction or metallurgical processing if the storer was engaged in mineral extraction and metallurgical processing within an initial active management area on or before January 1,  2011.
(d) The amount of central Arizona project water stored in an active management area in any year after 1994 by an agricultural improvement district established pursuant to title 48,  chapter 17 for use at those portions of electrical generating facilities that are constructed or expanded after June 12,  1980,  subject to both of the following:
(i) If groundwater was used during a year in an active management area at those portions of the electrical generating facilities that were owned and operated by the agricultural improvement district and that were constructed or expanded after June 12,  1980,  the amount of the central Arizona project water stored during that year equal to the amount of the groundwater withdrawn during the year for use at those portions of the facilities that were owned and operated by the agricultural improvement district and that were constructed or expanded after June 12,  1980 shall not be credited to the agricultural improvement district's long-term storage account but may be considered as being available for recovery by the agricultural improvement district on an annual basis under section 45-851.01.
(ii) Long-term storage credits accrued as a result of the storage of the central Arizona project water may be recovered within the active management area by the agricultural improvement district only for the purpose of providing central Arizona project water to electrical generating facilities that were owned and operated by the agricultural improvement district and only pursuant to any water requirement included in a facility's certificate of environmental compatibility. Subject to section 45-854.01,  the long-term storage credits may be assigned by the agricultural improvement district only to the owner of an electrical generating facility for use pursuant to any water requirement included in that facility's certificate of environmental compatibility.
(e) Surface water made available by dams constructed or modified after August 13,  1986.
(f) Effluent.

(h) If the storage facility is outside of an active management area,  water from outside the groundwater basin in which the storage facility is located that would not have reached the groundwater basin without the efforts of the storer.
(i) Water that is delivered through the central Arizona project and that is acquired by the Arizona water banking authority.
24. " Water storage"  means adding water to an aquifer or saving water in an aquifer pursuant to permits issued under this chapter.
25. " Water storage permit"  means a permit issued pursuant to section 45-831.01 to store water at a storage facility.
