49 Cuyama Basin Groundw ater Sustainability Agency Review of Preliminary Thresholds December 18, 2018

50 Board Direction on Minimum Thresholds Approved Motion from December 3, 2018 Board Meeting Direct Woodard & Curran to use Option D to develop preliminary threshold numbers.

51 Why Minimum Thresholds?  Required by SGMA  Establish Range of Operation in Groundwater Basin  Protect other Groundwater Pumpers  For Example: Keep Groundwater Levels High Enough to: 1. Ensure adjacent pumpers have access to groundwater 2. Protect access to groundwater in Community Services District well

52 Principals for Today’s Discussion  Thresholds are required to complete and submit the GSP by January 2020  Only establishing rationale for establishing initial thresholds  Initial threshold numbers will be discussed in January  Initial threshold numbers are only a starting point.  Initial threshold numbers will likely be modified as we gain greater understanding of the Basin.

Next Steps in Developing Sustainability Plan  Board approves draft sustainability thresholds  Identify projects and actions to achieve sustainable groundwater levels  Use numerical model to determine:  Long‐term sustainable groundwater pumping levels that maintain groundwater levels above minimum thresholds  Planned reductions in pumping between now and 2040 to achieve sustainable pumping levels (i.e. glide path)  Develop long‐term implementation plan  Includes response plan if levels fall below minimum thresholds

53 Where are Thresholds Applied? Minimum Thresholds are only applied to Representative Wells within the Monitoring Network .
