| Relation | Central Utah Project; Western Waters Digital Library; the operation of this alternative would be signif signia icantly scantly different from that of the alternative previously described water imported from strawberry reservoir through the syar tunnel would still flow through the syar penstock powerplant Power plant and reservoir corona aqueduct sixth water penstock powerplant Power plant and reservoir dyne aqueduct penstock and powerplant Power plant and then into monks hollow reservoir for reregulation during periods of low power demand however part of the water would be pumped from monks hollow reservoir back through the system to sixth water andsyar reservoirs to be released back through the system during peak demand periods from monks hollow reservoir some releases would be made to the diamond fork up to 300 cfs cs and any flows in excess of the channel capacity would be released to the diamond fork pipeline up to 400 cfs cs to be conveyed directly to the spanish fork river three above ground surge tanks would be constructed to relieve rapid changes in pressure in the system the basic concept behind this type of pumpback humpback pump back storage system is that hydroelectric power is generated as water is released from an upper reservoir and run through a powerplant power plant during peak demand periods during low demand periods the water is pumped back from the lower reservoir to the upper reservoir although there is a net loss in energy the power is produced when it is most needed and can thus be sold at a premium price the pumping back to the upper reservoir occurs during low demand periods when the energy is available at lower rates usually reversible turbines are installed and can be used as either generators or pumps simply by reversing their direction the power generation for this alternative is based on an average operation of 6 hours at full generating capacity each day excluding weekends and holi days with 11 hours per day at full capacity during emergencies project flows during the month of july would normally be sufficient so that no pumpback humpback pump back would be required b environmental impacts construction of this alternative would provide an estimated 3300 jobs during the peak year and would provide about 130400000 in income over a 5 year construction period operation and maintenance would provide about 55 permanent jobs with a combined annual income income of about 1050000 the only significant impact on water quality would be an overall reduction in sediment yield in diamond fork monks hollow reservoir would remove a large part of the sediment that presently originates above the monks hollow adamsite damsite and would reduce the sediment yield from diamond fork to the spanish fork river by about 44 percent or about 72 tons per day the serious erosion problem on the lower diamond fork would be curtailed as a result of reduced streamflows stream flows other water quality considerations would not be significantly affected H 19 |
