22-32 Water Supply Plan

22-32 There are four (4) water balance diagrams showing different typical scenarios, but none of the scenarios include evaporative cooling usage.

  1. How much of the water used during the evaporative cooling scenarios would be consumptive (i.e., result in losses that would require make-up water)?
  2. What would be the source of this water?
  3. How would it be supplied to the site?

RESPONSE 22-32

Sheet 2 of the water mass balance attached to the Water Supply Plan specifies 4,600 gallons per hour for 2 units which is approximately 39 gallons per minute for each unit at 90F degrees and 45% relative humidity. This is the consumptive loss during those conditions, assuming both units at full load output.  As stated in Response 22-31, the typical consumption will be lower.

The water needed for evaporative cooling is a 50/50 blend of service water and demineralized water. The water utilized for this purpose will be the same source as the water indicated in the Water Supply Plan and there is no special source for this water supply.

All needed water will be trucked to the Facility as described in the Water Supply Plan.

Please refer to water mass balance diagram, Appendix C, furnished as a part of the Water Supply Plan, which depicts the source of water within the plant that feeds the evaporative coolers, to better understand the flow.
