Jack and I discussed the four issues and it <br /> was agreed that I would analyze the proposed changes in <br /> cost sharing requested by the Administration. <br /> Jack has asked Interior and Agrit:ulture for additional <br /> information on this item. I decided to send this memorandum <br /> and we will forward any other information as soon as we re- <br /> . <br /> • • ceive it. <br /> Background <br /> The thrust of the statements made by Interior with re- <br /> spect to cost sharing is to retain the 75 percent federal <br /> and 25 percent non-federal cost sharing for the entire <br /> salinity control program, but to have the non-federal share <br /> either paid as up-front financing or to be paid over 50 years <br /> with interest at the average federal long-term interest cost. <br /> The impact of these alternatives was analyzed using infor- <br /> mation developed by the salt routing model used for the Forum <br /> salinity projections , assuming a long term dependable yield <br /> of 14 million acre-feet per year and a continuation of the <br /> low rate of basin development. Based on this analysis , the <br /> full impact on the River's salinity of upstream development <br /> would occur in the year 2020 . <br /> The three authorized salinity control units , Grand Valley, <br /> Paradox Valley and Las Vegas Wash, are projected to re;rove <br /> about 660, 000 tons annually. In order to maintain the nulneri: <br /> criteria, an additional 1 . 4 million tons of ::alt must be pre- <br /> vented from entering the river system. <br /> • <br /> • <br />
