Section 785:30-9-2 - Determination of maximum annual yield(a)After completing the hydrologic survey, the Board shall make a tentative determination of the maximum annual yield of groundwater to be produced from each major groundwater basin or subbasin therein. Such determination shall be based upon the following:(1)The total land area overlying the basin or subbasin;(2)The amount of water in storage in the basin or subbasin at the time of the survey or investigation;(3)The rate of recharge to the basin or subbasin and total discharge from the basin or subbasin the time of the survey or investigation;(4)Transmissibility or transmissivity of the basin or subbasin; and(5)The possibility of pollution of the basin or subbasin from natural sources.(b)The maximum annual yield of each groundwater basin or subbasin shall be based upon a minimum basin or subbasin life of twenty (20) years fromthe order establishing the final determination of the maximum annual yield. [82:1020.5](c)For minor groundwater basins or subbasins therein, the tentative determination of the maximum annual yield shall be based upon present and reasonably foreseeable future use of groundwater from such basin or subbasin, recharge and total discharge, the geographical region in which the basin or subbasin is located and other relevant factors. [82:1020.5(C)](d) The maximum annual yield of each minor groundwater basin or subbasin shall be based upon a minimum basin or subbasin life of twenty (20) years from the order establishing the final determination of the maximum annual yield.(e) The maximum annual yield for a sensitive sole source groundwater basin or subbasin will ensure that any permit for removal of water from the basin or subbasin will not reduce the natural flow of water from springs or streams emanating from said basin or subbasin[82:1020.9A(B)(2)].Okla.
