After hearin.gs in Las Vegas, Nevada, and Denver, Colorado, in <br />August 1974, the final regulation was published on December 18, 1974, in <br />the Federal Register, The regulation states that 40 CFR Part 120 is <br />amended by adding Section 120,5 Colorado River System Implementation <br />Plan, which reads as follows: <br /> <br />"(a) 'Colorado River System' means that portion of the Colo- <br />rado River and its tributaries within the United States of <br />America. <br /> <br />"(b) It shall be the policy that the flow weighted average <br />annual salinity in the lower main stem of the Colorado River <br />System be maintained at or below the average value found <br />during 1972. To carry out this policy, water quality <br />standards for salinity and a plan of implementation for salin- <br />ity control shall be developed and implemented in accordance <br />with the principles of paragraph (c) of this section, on the <br />following page, <br /> <br />"(c) The States of Arizona, California, Colorado, Nevada, New <br />Mexico, Utah, and Wyoming are required to adopt and submit for <br />approval to the Environmental Protection Agency on or before <br />October 18, 1975: <br /> <br />"(1) Adopted water quality standards for salinity in- <br />cluding numeric criteria consistent with the policy <br />stated above for appropriate points in the Colorado River <br />System, and <br /> <br />19 <br />
