solids have the same meaning.) Although the project is not in the <br />Lower Colorado River basin, the regulations still influence the • <br />project. <br />The numeric standards for salinity in the Colorado River are: <br />Below Hoover Dam - 723 mg/1 <br />Below Parker Dam - 747 mg/1 <br />Below Imperial Dam - 879 mg/1 <br />The salinity standards state that "the objective for discharges <br />shall be a no-salt return policy whenever practicable." This <br />policy will be followed when issuing NPDES permits for new in- <br />dustrial sources. There are provisions to allow increases in <br />salinity where no-discharge of salt may be considered not to be <br />practicable. <br />3.3.7.2 Alkali Creek <br />A surface water monitoring program was initiated on Alkali Creek • <br />on December 12, 1981. The program consisted of quarterly water <br />quality sampling and analysis and monthly field measurements at two <br />monitoring locations (ALK-1 and -2), shown on Figure 3.3-6. The <br />water quality samples are analyzed for parameters listed in Table <br />3.3-8 by Core or Industrial Laboratories in Denver, Colorado. <br />Results of the program and statistical analysis are listed in <br />Appendices 3.3-10, 3.3-11, and 3.3-12. Monthly field measurements <br />include specific conductance, pH, dissolved oxygen, temperature and <br />flow, Flow measurements are made at both sites with nine-inch <br />Parshall Flumes. <br />The monitoring program on Alkali Creek was re <br />which was approved by CMLRD in a letter from <br />Herron dated August 15, 1983 (Appendix 3.3-13). <br />reduced to monitor only the downstream station, <br />field measurements and quarterly water quality <br />NCEC - Coal Ridge #1 3-44 <br />duced during 1983, <br />Roy L.
