In order to be approved, an out-of-basin-diversion application shall demonstrate to the Commission’s satisfaction, the amount of water in the basin of origin available for future appropriation in the basin of origin and for the proposed use. In demonstrating water availability, the application shall include an analysis of:(a)
Annual and monthly discharge for the basin as a whole and for the specific surface or groundwater source proposed for diversion. Analysis shall include at least the 80 percent frequency discharges and reflect both natural (without storage or diversion) and regulated conditions at the mouth and the point of diversion. Discharge shall be expressed in units of cubic feet per second and acre feet;(b)

Economic factors affecting water use in the basin of origin.(3)
In order to be approved, an out-of-basin-diversion application shall demonstrate to the Commission’s satisfaction, that the proposed diversion will not harm return flows that benefit water users in the basin of origin. At a minimum, the analysis shall include:(a)
An evaluation of existing and prospective water use by major use category on the proposed diversion source upstream from the proposed point of diversion;(b)
An estimate of the existing and prospective amounts of water that return to the proposed source of diversion upstream from the proposed point of diversion;(c)
An evaluation of existing water rights issued specifically on return flows, effluent discharge, wasteways or recycled water originating upstream and passing the point of diversion for use downstream.(4)
In order to be approved, an out-of-basin-diversion application shall demonstrate to the Commission’s satisfaction, that the proposed diversion will not harm supplies of surface or groundwater in the basin of origin. The application shall describe the relationship between surface and groundwater and, at a minimum, shall include:(a)
An identification and discussion of groundwater recharge and discharge zones and how surface water and groundwater affect each other in these zones;(b)
An identification of areas where groundwater and surface water are or may be hydraulically interconnected and a discussion of annual and seasonal exchange between these resources;(c)
An evaluation of the relationship between water quantity and quality for both surface water and groundwater and how conditions present in one resource affect conditions in the other;(d)
An evaluation of whether the proposed project will occur in an area of groundwater-surface water hydraulic interconnection and if so, a discussion of the potential and expected impacts of the proposed project on the quantity or quality of either;(e)
In responding to subsections (a) through (d) of this section, any assumptions relied upon or modeling conducted by the applicant shall first be reviewed and approved by the Department.(5)
