The program will reduce the <br />annual salt load to the San Juan River by 32,000 tons and also <br />reduce the salinity concentration at Imperial Dam by about 3.5 <br />mg/l. The total cost is estimated at $29,800,000 and would yield <br />a cost-effectiveness of approximately $750,000 per mg/l. <br /> <br />Impacts <br /> <br />The major impacts of this program for the Montezuma Valley <br />are similar to those for the Grand Valley and Lower Gunnison <br />areas. As with those units, the economicl environmental 1 legal~ <br />and operation, maintenance, and replacement impacts are <br />sign i ficant. <br /> <br />The cost-sharing provisions of this program create <br />substantial economic impacts. The farmers in the Valley would <br />have to raise 25 percent of the total project cost in order to <br /> <br />-25- <br />
