<br />oaaOo7 <br /> <br />. <br /> <br />Differences exist in Reclamation's and USDA's view of economic evaluations, <br />estimates of salt tonnage contributions, and scheduling of program implemen- <br />tation. Some of these differences will be resolved during ongoing interagency <br />discussions. For the evaluations using CRSS, USDA projections were provided <br />by SCS. <br /> <br />- <br /> <br />Non-Federal Salinity Control Activities <br /> <br />The Forum's plan of implementation to meet the numeric criteria for salinity <br />includes two major, non-Federal program activities: <br /> <br />1. The placing of effluent limitations, principally under the NPDES <br />(National Pollutant Discharge Elimination System) permit program on <br />industrial and municipal discharges in the basin. <br /> <br />2. Implementation of 208 Water Quality Management Plans for erosion <br />control, nonpoint source salinity control, and improvements in irrigation <br />systems and irrigation water management. <br /> <br />Presently, there are about 100 NPDES industrial permits issued for the <br />seven states. The present or future salinity impacts of the permit system <br />have not been documented. Moreover, the present track record is not encourag- <br />ing. Several powerplants in the basin continue to return saline waste- <br />water to the river system; namely, Four Corners Powerplant in New Mexico, <br />Jim Bridger Powerplant in Wyoming, and possibly Hunter and Huntington Canyon <br />Powerplants in Utah. In some cases, the utilities have convinced the State <br />regulatory agencies that discharge control technologies are too expensive. <br />In other cases, we understand that the permits are short term with ultimate <br />zero discharge still in question. <br /> <br />The outlook for implementation of 208 Plans is equally discouraging in <br />providing any substantive salinity reductions. Although many 208 plans have <br />been certified by the State or EPA (Environmental Protection Agency), contin- <br />ued EPA funding for implementation of the plans has been drastically reduced <br />or eliminated. <br /> <br />Colorado River Enhanced Snowpack Test and Full Basin Operational Program _ <br />Reclamation <br /> <br />The results of recent simulations of cloud seeding with the CRSS model have <br />been examined. Three sets of simulations, with 15 hydrology traces each, <br />were run for a 90-year period from 1982 to 2072. The simulations were <br />divided into three periods: <br /> <br />1. 1983 to 1985. - Lead-in period of no cloud seeding. <br /> <br />2. 1986 to 1990. - Demonstration period with 340,000 acre-feet per year <br />streamflow enhancement. <br /> <br />3. 1991 to 2072. - Operational period with 1,430,000 acre-feet per year <br />streamflow enhancement. <br /> <br />9 <br />
