<br />(l'{J '::J i <br /> <br />. <br /> <br />. <br /> <br />Also in the handout is a copy of a report, prepared by the Grand County Council, entitled <br />Atlas Uranium Mill Tailings Site, Grand County, Utah. Mr. Al McLeod, Chairman of the Grand <br />County Council, has requested an opportunity to discuss Grand County's concerns with the Board. <br /> <br />Perchlorate Contamination in the Las Vegas Wash <br /> <br />Included in the Board handout is a draft letter to be sent from the Board to the Administrator <br />of the Environmental Protection Agency (EP A) requesting its support in cleaning up the perchlorate <br />contamination in the Colorado River emanating from the Henderson, Nevada area. Kerr-McGee, <br />the company from whose property the contamination is emanating, has agreed to intercept the <br />groundwater contamination at its property line and divert it to on-site evaporation ponds. By this <br />letter, the Colorado River Board is requesting that the EPA assist the Southern Nevada Water <br />Authority in intercepting the groundwater contamination off-site of Kerr-MeGee's property before <br />it can reach the Las Vegas Wash and enter the Colorado River. <br /> <br />Yuma Desalting Plant <br /> <br />Included in the Board folder, as an informational item, is a letter from Reclamation which <br />discusses the operational status of the Yuma Desalting Plant, and the condition of the reverse <br />osmosis membranes. As you are aware, this facility has been placed in a ready-reserve category due <br />to the hydrologic conditions that are currently existing on the Colorado River System. Reclamation <br />has estimated that it would take approximately 24 months to bring the plant from zero operation to <br />operation at full capacity, at a cost of approximately $33 million. Subsequent year O&M costs are <br />estimated at $24 million per year. <br /> <br />r <br /> <br />~e.~.!>"'J_"~""- <br /> <br />.- Gerald R. Zimmerman <br />Executi ve Director <br /> <br />7 <br />
