We would need to see the engineering studies behind the proposed expansion before accepting that explanation. It seems to me that the major element of the work--which is the excavation needed to increase Iws system pond volume by 46 million gallons (or 141 acre-fee') above the current volume of 26 million gallons--is driven primarily by the need to accommodate proposed Master Plan Improvements __ which include the 3rd runway.
