This information is essential <br /> <br />for an appraisal of the development's impact on the state's water <br /> <br />resources. <br /> <br />In addition, our staff believes that a significant <br /> <br />amount of water quality degradation will accompany the development, <br /> <br />and the U. S. Forest Service has not included an evaluation of <br /> <br />this impact in their statement. Water pollution as a result of <br /> <br />the Beaver Creek development will come from two sources--sewage <br /> <br />treatment plant effluent and urban runoff. Of primary interest to <br /> <br />the Water Conservation Board is the increased salinity or total <br /> <br />dissolved solids resulting from the development, and we believe <br /> <br />that urban runoff will be the largest contributor. <br /> <br />The Federal Water Quality Act of 1972 in Section 303(b) <br /> <br />requires the establishment of water quality standards on the <br /> <br />Colorado River. It now appears certain that these standards will <br /> <br /> <br />be the salinity levels existant during April 1972. What this means <br /> <br /> <br />to those of us in the water resources field is that each new <br /> <br /> <br />development or water use causing an increase of salinity after <br /> <br />April 1972 either by loading or concentration must be accompanied <br /> <br />by an equivalent water quality improvement. <br /> <br />-2- <br />
