Show 125 that no other actions are taken, that pond areas remain constant, and that an inflow of 3.41 million acre- feet occurs during the 1975 water year ( October 1, 1974 to September 30, 1975). Table 26 shows the relationship of sodium chloride sales to pond output with brines created by 30- foot and 200- foot openings in the causeway. Table 27 indicates the relationship of pond capacity, output and density of feed brine for magnesium, potassium sulphate and sodium sulphate for the same openings. These tables illustrate some of the adjustments which would be required of the industries to maintain production levels if modifications were made in the causeway. Table 28 shows, in thousands of dollars, the economic impact of opening the causeway. The analysis is based on sales over the 30- foot capacity and under the 200- foot capacity taken from a time profile of sales. With changes ranging from a loss of $ 15,000,000 for GSLC& M to a gain of $ 3,720,000 for Morton, the net change is shown as a loss of $ 8,535,000. Aside from the extractive industries, studies have shown that opening the causeway would have a positive impact on the shrimp industry. Presently, the North Arm is so saline that the brine shrimp have difficulty surviving in those waters. Although there is no substantial evidence, it also appears that the brines in the South Arm are so dilute that the winter eggs of the shrimp are being affected. The brine shrimp industry is expected to experience an increase in harvesting viable brine shrimp eggs of up to 140 percent as a result of opening the causeway from 200 to 500 feet. At shown in Table 29 it has also been calculated that transporting |
