The locations of these structures should also be shown <br /> on the Exhibit F map. If details for any proposed final structures are not known at this time, <br /> please commit to submitting a Technical Revision to provide these details at a later date. <br /> Response: The locations and types of reservoir infrastructure are not known for <br /> the large north reservoir cell and the south reservoir cell at this time. PAO <br /> commits to submitting a technical revision to provide these details when they are <br /> known. <br /> The small north reservoir cell has a 24 inch cmp inlet pipe on the west side of the <br /> cell that receives water from a farm ditch along the west boundary of the cell and <br /> discharges into a concrete rundown down the west slope of the cell. A floating <br /> pump station has been installed to pump water out of the reservoir back to the <br /> farm ditch to discharge water from the reservoir back to the river. See the <br /> attached photos of the concrete rundown and floating pump station and revised <br /> Exhibit F Reclamation Plan Map. <br /> 19) Please specify the temporary seed mixture for topsoil stabilization, including seeding rates <br /> in PLS/acre. <br /> Response: When seeding of the temporary topsoil stockpiles is required the seed <br /> mix will be the same as the permanent reclamation seed mix. The proposed seed <br /> mix is shown in the following table. <br /> Seed Mix Application Rate` <br /> Alkali Sacaton(Saltalk) 1.5 PLS/ac <br /> Switchgrass(Blackwell or Pathfinder) 4.0 PLS/ac <br /> Blue Grama(Hachita or Lovington) 3.0 PLS/ac <br /> Western Wheatgrass(Arriloa, Barton, Rosana) 16.0 PLS/ac <br /> Sideoats Grama(Vaughn, E/Reno Niner) 9.0 PLS/ac <br /> Buffalograss (Texoka, KNO3 treated, or native within 150 miles 6.0 grain or 16.0 bur <br /> of site) <br /> Application rate is for drilling the seed.
