With time, these concentrations are likely to <br />decrease. <br />According to Mr. Kawanabe tsf the Netibna] Resoutt;e Conservation Service at the San Luis field <br />atftCe, both sulfate and mangattese are mil:ronutrients which can be utilized by the crops being <br />grown on the Rocky Mountain Fartns, 2nd Mr. Kawattabe does not believe the use of the West <br />Pil water in this manner will cause any Crop yield rcducdons or salt buildup in the soils. Based <br />on this assessment, andtf the agricultural standards arc met, the use of the West Pit water for <br />irrigation is agreeable to Mr. David Feticette, the owner of the Rocky Mrntnrrin Corms. <br />Rased on this alternate plan for using wt~ter from the West Pit in a beneficial manner, HMRi will <br />request a substitute supply plan (SSP) from the Division Engineer's Office rhat would allow BMRI <br />to operate in this matmer through the summer oP 2000. HMRi, through its water cqunsel, would <br />alsu apply m Division 3 Water Court fora change of water right which would adjudicate the uses <br />envisioned herein, as well as the augmentation required for this use. <br />In summary, the BMRI SSP would allow BMRI to pump waur from the West Pit to the extent <br />rnxessary to achieve the objectives set uiaier TR 26. The water pumped from the West Yit would <br />be metered, and would be augmented 1:'i, essentially contemporaneously with the pumping, by <br />delivering well water from [he Rocky Mountain Farrtts to Rito Seco at the same delivery puint <br />(upstream of the Salaiar Ditch), that is; curretuly used under the aul5tncntntiun plan decree in <br />89CW32, The 1:1 replacement is warranted due to the proximity of the West Pit to Rito Seco anti <br />the very large aquifer transmissiviry in'the West PIt from the placement of backPill materials <br />which will result in ahoct travel times -tu the Rito Seen alluvial/stream system. BMRI would <br />propose developing the timing of its augrentation requirements wilt its West Pit pumping in <br />cooperation with the Division F.agitteer's Offiee. These values would then be documented on <br />HMRI's current augmentation plan accounting form. <br />-3- <br />
