c..., 0) "'-' o Other Activities Colorado has continued its support of the basinwide approach to salinity control through its participation in the Colorado River Basin Salinity Control Forum and associated activities. This has included silnificant efforts on proposed Forum amendments to the Colorado River Basin Salinity Control Act and the :Clean Water Act and coordination with local entities havinaan interest in the legislation. The State of Colorado has also put significant work into the Grand Valley Salinity Control Unit coordination efforts since installation of facilJitiesbegan in 1979. The Colorado Water Conservation Board, under a arant from Reclamation, assumed responsibility in 1985 for working with the irrJaation water .upply entities in the Grand Valle~. to orilanize the private individual laterals in the area into le~al entities with whom~eclamation could contract for the O&M of the laterals after they are lined or placed in pipe. That effort has now proceeded to the point that Reclamation will begin working directiy with the s,everal entities which are considering assuming the ownership of the private laterals which are to be improved. The Colorado Soil Conservation Board, with support from other state agencies, is continuing its work with the 8CS, ASCS, and local soil aonservation districts to direct, as appropriate, available fede''l'al soil conservation funding programs towards improvement of onfarm irrigation practice. The salinity control benefits of improved practices are one of the reasons for this effort. The water rights issues have been resolved between the State of Colorado and Reclamation. The Water Court has issued conditional decrees for the ground water wells and ' an ab~olute decree for Reclamation's change of water tight and plan of augmentation. ,The State has also approved pumping and well testing as stipulated in the existing well permits. The state has continued to encourage the industrial use of saline water, particularly by the oil shale and mining industries. All environmental assessments and impact statements concerninil oil shale development were re~iewed and opportunities for saline water use identified as appropriate. Nevada NPDES Permits EPA has delegated the Nevada Division of Environmental Protection authority to issue NPDES Permits.' Basic Manailement Industries has eliminated industrial wastewater dischariles to Las Vegas Wash. The industries now pipe waste water to lined ponds where it evaporates. Two of the companies have been issued permits which allow discharge of cooling water to Las Vegas Wash with a limit of no more than 75 mg/l TDS increase over the water supply. Another Basic Management Company has been issued a permit which allows discharge of surface storm runoff. -52- '.
