National Park Service March 7, 2007 – Federal Register Recent Federal Regulation Documents

Pursuant to Sec. 102(2)(C) of the National Environmental Policy Act of 1969 and the corresponding Council of Environmental Quality implementing regulations (40 CFR parts 1500-1508), the National Park Service and Bureau of Reclamation, as lead agencies for the Department of Interior, announce the availability of the Clean Water Coalition Systems Conveyance and Operations Program (SCOP) Final Environmental Impact Statement (Final EIS). The SCOP Final EIS completes the evaluation of potential environmental impacts associated with a proposed pipeline alternative, two additional pipeline alternatives, and the baseline No Action alternative (and also presents a Process Improvements option derived from the No Action Alternative). The purpose of implementing the proposal is to put into operation a treatment and conveyance system that will allow for flexible management of wastewater flow in the Las Vegas Valley, while maintaining water quality standards. Clark County, Nevada is one of the fastest growing counties in the U.S., with a projected population in the area of approximately 3,130,000 by 2035. The quantity of effluent treated and discharged in the Las Vegas Valley will increase with the Valley populations. The treatment and conveyance facilities must accommodate the additional flows while continuing to meet current or future water quality standards for Las Vegas Wash and Bay, and Lake Mead. The Final EIS evaluates effects of the alternatives on both visitor experience and park resources including: surface water hydrology, groundwater, water quality, biological resources/endangered species, cultural resources, recreation, land use, air quality, noise, socioeconomics, and other appropriate resource issues identified during the public scoping phase. An impairment analysis was also completed by the National Park Service (NPS) for the portion of the proposed actions that would impinge upon this unit of the National Park System.
