Environmental Assessment Upgrade of the Indian Springs Collection and Treatment System.

摘要

Clark County Water Reclamation District proposes to upgrade the existing wastewater treatment facility for the City of Indian Springs, Nevada. This upgrade will prevent nutrient leaching into the groundwater from unlined sewage treatment and disposal lagoons. The proposed project involves constructing a wastewater treatment plant to remove nutrients and converting existing treatment lagoons to percolation ponds, and constructing additional percolation ponds. This work would take place within the footprint of the existing wastewater treatment facility property. This project also includes other improvements to wastewater collection systems in Indian Springs to re- route sewer lines around high hazard commercial properties. In addition, The United States Air Force (USAF) proposes to abandon its current wastewater treatment system on base and construct a wastewater transmission pipeline to the existing Indian Springs lift station. The existing Creech Air Force Base (CAFB) Wastewater Treatment Plant (WWTP) will be demolished and removed, and the current treated effluent discharge ditch will be filled in. The USAF will help fund capacity and treatment improvements at the Indian Springs facility. The Environmental Assessment (EA) provides an analysis of the potential environmental consequences resulting from implementing the proposed action and the alternatives, including no action. Several resources were assessed that in accordance with Council on Environmental Quality warrant no further examination in the EA. These resources were coastal zones, floodplains, land use, and infrastructure demands. Nine resource categories were thoroughly analyzed to identify potential impacts. The following summarizes and highlights the results of the analysis, by resource categories, that initial evaluation indicated could be effected by the proposed action.
