<br />I <br /> <br />I <br />I <br />I <br />I <br /> <br />For canal lining, the estimated salt-load reduction would be 700 tons <br />at a cost of $2,600,000, which results in a cost of $325 per ton. For <br />piping, the estimated salt-load reduction would be 820 tons at a cost <br />of $7,000,000, which results in a cost effectiveness of $750 per ton. <br /> <br />Brush Creek Area <br /> <br />The Brush Creek area joint project was not investigated due to lack of <br />manpower and other work priorities. Using Price-San Rafael Rivers <br />Unit joint project costs, a cost effectiveness of $129 per ton was <br />estimated. This is based on a salt-load reduction of 1.1 tons per <br />acre and a total project cost of $142 per acre. <br /> <br />I <br />I <br />I <br />I <br />I <br /> <br />Whiterocks-East Uinta Area <br /> <br />The Whiterocks-East Uinta area joint project was not investigated due <br />to lack of manpower and other work priorities. Based on Reclamation <br />data, projects in this area would not be cost effective. There may be <br />some isolated areas of higher salinity; however, additional data <br />collection and studies would be needed to verify this possibility. <br /> <br />RECLAMATION ONLY PROGRAM <br /> <br />Brush Creek Area <br /> <br />I <br />I <br /> <br />The Brush Creek area canals were studied in the greatest detail due to <br />the lack of any previous data and the possibility of a cost-effective <br />project. Salt-load reduction estimates are based on canal seepage <br />measurements and Uinta Basin Stage I studies. The cost estimates are <br />based on January 19B9 prices. As shown in table 3, all of the costs <br />per ton are greater than $100, which indicate the project is not cost <br />effective. <br /> <br />I <br />I <br />I <br /> <br />My ton Townsite Canal <br /> <br />Table 4 contains an incremental analysis for lining shorter lengths of <br />My ton Townsite Canal. This subarea is the next most cost effective <br />after the areas which are included in the recommended plan for <br />phase I. <br /> <br />I <br />I <br />II <br />I <br /> <br />The salt reduction is based on previous mass balance studies for My ton <br />Townsite Canal, and the costs are based on January 1989 prices. As <br />shown in table 4, lining about 3.2 miles of My ton Townsite Canal <br />(reaches 1, 3, and 6) would be cost effective on a cumulative basis. <br />This would remove about 2,150 tons of salt at an annual cost of <br />$192,650, which results in a cumulative cost effectiveness of $90 per <br />ton. <br /> <br />(1/ , ,~ t" c. -. <br />,..1 '." ~ ,,_, f.....
