Future Additional ASR:

On March 16, 2012 District staff met with John Kilpatrick of Cal Am to discuss future potential ASR from existing facilities in the Carmel Valley. This was a follow-up to a meeting District staff had with Cal-Am on the future of ASR on January 25, 2012.

EXHIBIT 4-A summarizes the Cal-Am analysis. Cal-Am examined existing facilities two ways: (i) based on well capacity (the upper portion of the exhibit), and (ii) based on BIRP plant capacity (lower portion of the exhibit.)

They looked at all wells in operation (“Total”), as well as what happens if their largest wells in the lower valley and the upper/mid-valley, Rancho Canada #2 and Robles #3 respectively, are off-line (“Firm”).

The conclusions are as follows:

1) Based on well capacity, there is no additional potential for ASR from Carmel River water; and

2) Based on plant capacity, there is potential for 2,550 GPM under most conditions, but only 1,900 GPM “Firm.”

Hence, this might support two additional ASR wells, but would require the development of new well capacity. If existing wells cannot be improved, then new wells would be required, likely requiring an EIR. Further, we have been advised that ultra-violet (UV) treatment would likely be required at the BIRP facility. These additional capital costs would need to be calculated and included in the cost of any additional ASR facilities.

In both cases, Cal-Am is assuming that in the future they will be pumping 1,750 gallons per minute for Table 13 water rights for which they do not currently have a permit. If they do not succeed in obtaining those rights, the well capacity constraint remains on a Firm basis, but there might be approximately 1,400 GPM of available pumping capacity in normal conditions. On a plant capacity basis the full 1,750 GPM would be additionally available.

EXHIBIT 4-B is additional analysis performed by District staff which confirms the constraints. Joe Oliver will provide a verbal report.
