Environmental Assessment for Enhanced Use Lease of U.S. Air Force Lands to the City of North Las Vegas for Construction and Operation of a Water Reclamation Facility, Nellis Air Force Base, Nevada

摘要

The U.S. Air Force (USAF) proposes to initiate an Enhanced Use Lease (EUL) with the City of North Las Vegas (CNLV) for 40 acres of Nellis Air Force Base (AFB) property located at the southwest corner of the installation. The Nellis AFB property is currently developed as part of the Nellis AFB Sunrise Golf Course. The CNLV would construct a water reclamation facility (WRF) on the property in phases as population increases and other conditions warrant. The initial phase of the WRF would treat approximately 20 million gallons of wastewater per day (mgd); ultimate capacity would be 50 mgd. The WRF would include closed treatment basins, administration and maintenance buildings, warehouse buildings, pump stations and wastewater treatment process structures, and parking space for employees and moveable equipment. All of the treatment basins would be primarily below ground level, with approximately 6 feet visible above ground. The buildings would be painted to match the surrounding desert landscape, and the tallest structure would be 55 feet tall. The WRF would use advanced membrane technology, ultra-violet (UV) disinfection, completely filtered air emissions for odor control, and solids reduction technology. A wall and fence would be constructed to surround the WRF, and access would be secured 24 hours per day, seven days per week. The CNLV would supply Nellis AFB with reclaimed water from the WRF sufficient to irrigate the golf course, as well as for other non-potable uses on the installation. Excess reclaimed water would be discharged to Sloan Channel, located approximately 500 feet east of the property. The EUL to the CNLV for the WRF would also provide the USAF with funds to repair aging infrastructure. Alternatives to the Proposed Action were previously addressed in an Environmental Assessment (EA) developed for the Bureau of Reclamation (RECLAMATION) by the CNLV in 2007.
