The site location and property boundaries are shown on Exn~bd F-1. For reference, the original topography s presented in Exhibit F-5. and the 'as-bmlt" cond bons are shown ~n Exhibds F-6 and F-7 In accordance with the original permit appacation. and to retain the possib:!•ty of eventually returning this area to agricultural use jgraziny~, the topsoil was stnppea and stockpiled in 1981. Planned development of this area would occupy nearly the entire permitted 'area to accommodate the two large sedimentation basins and assdciated pumping plant needed td capture sediment from river water as the first step m treating the water for plant feed water The large pumping plant which would IiH the treated water 2,300 vertical feet and t3 miles north to M1liddle Fork Dam has yet to be constructed. but will occupy the western edge of the site. A large intake structure rn the Colorado was designed to allow pumping or as much as 13.000 gpm and a sustained water feed rate of approximately 8,000 gpm In 1983 the `m aver- portwns of this lacility were constructed, corsistent with a US Army Corps of Engineers 40a permit covering construcl~on of the temporary cofferdam In the aver. Later in 1986 the land-ward earthwork anC bused piping for the large sedimentation basins were installed, still holding to the design capacdy described above.
