<br />Mr. Hichald Gorgon <br />Apr i 1 22, 19t17 <br />P..H;} ~ 'fh L ce <br /> <br />the water in the river 1000 meters downstream] <br />from Grand Junction sewage treatment plant is n t <br />meeting state water quality standards. <br /> <br />This is very restrictive and any depletion that <br />would have an impact on these standards and <br />require our District to discontinue use of its <br />pumping plant must be evaluated and discussed in <br />detail in the E.I.S. <br /> <br />We suggest that standard flow and water quality <br />restrictions to be adopted by the Corps for <br />Denver should be the same as those imposed by the <br />Corps on our District otherwise they would be <br />preferential and discriminatory. The priority <br />for the Two Forks water rights to be diverted <br />from the Colorado River drainage are junior to <br />the priority for our Bridges Switch pumping <br />plant. <br /> <br />3. The E.I.S. should discuss salinity impacts caused <br />by depletions during the dry years measured at <br />Cameo rather than averages. Any increase in <br />salinity at Cameo could have a detremental impact <br />on agricultural crops and treatment of municipal <br />water. These impacts should be recognized and <br />mitigated. Increases in salinity at Imperial Dam <br />is another matter. <br /> <br />We suggest a tabulation be made showing the minimum flows <br />at Cameo which result from depletions and the effect this will <br />have on salinity and quality of water. <br /> <br />We appreicate the opportunity to comment on the E.I.S. <br /> <br />Sincerely, <br /> <br />V~ef'~~ <br /> <br />PC/cgh <br /> <br />Paul Calder <br />Manager <br /> <br />cc: G.W.
