<br />This tabulation shows the total investment costs could range from about
<br />$690 million to $770 million, depending upon which alternatives are selected
<br />as the recommended plans for construction.
<br />
<br />In the September 1981 Saline Water Use and Disposal Opportunities Special
<br />Report, investment and annual costs were calculated for local use energy
<br />development alternatives at various saline water sources. In all cases,
<br />only the costs of providing water to the powerplant boundary were included.
<br />The necessary incremental costs for using the saline water for cooling were
<br />not considered at this time. Table 8 presents those costs.

<br />II Construction costs plus interest during construction, 1981 costs.
<br />
<br />Three of the sources were evaluated in preliminary detail to show specific
<br />features and their costs. After adjustments were made for incremental
<br />costs inside the pl ant boundary and a credit given for their alternate
<br />water supply, the cost-effectiveness for Federal expenditures changed.
<br />This change is shown below only to emphasize that cost-effectiveness and
<br />adjustments vary widely from site to site.
