SITE NAME: LAS VEGAS AIR FORCE STATION; also known as Las Vegas AF Station, Las Vegas Air Force Station Z-163, Las Vegas Air Force Station SM-163, Las Vegas AFS 163, Air Force Station SM and Las Vegas Z163 AFS. Current name of the Air Force GATR facility, mentioned below, is Nellis Communications Annex/Angel`s Peak. Current name of the Clark County juvenile detention facility, mentioned below, is Spring Mountain Youth Camp.

LOCATION: The Las Vegas Air Force Station site is located on Angel Peak, approximately 26 miles northwest of Las Vegas, Nevada, lying within Sections 9 and 10 of Township 19 South, Range 57 East. It is situated approximately 2.0 miles northeast of Highway 158 by way of the access road to Hilltop Campground.

SITE HISTORY: The Air Force acquired the Las Vegas Air Force Station (LVAFS) site by transfer, fee, and easement during the period 1955 to 1963. The Air Force used the LVAFS site as a communication/radar facility and weather station.

From 1956 to 1967, the Army had in its possession a 0.02-acre site known as Angel Peak Radio Relay Station (Formerly Used Defense Site J09NV022500). It was located inside the northern LVAFS boundary. It had no known impact on the LVAFS site.

DOD constructed about 24 main buildings in two LVAFS areas, the Operations and Cantonment Areas. Construction in the Operations Area consl:`sted of four radar towers, four operational buildings, one water pump station, a power building, and five large aboveground fuel tanks. The Cantonment Area contained approximately 5 dormitories a dispensary, a mess hall, an administration building, an automotive shop, a maintenance shop, a storage building, a recreation building, one underground gasoline storage tank, and one large above-ground fuel oil tank. Each building had a smaller day tank for storage of heating oil. Three septic tanks comprised the sewage treatment system.

In 1970 the Air Force relinquished the property to the Department of Interior and transferred accountability for all improvements, with the exception of Buildings 18 and 40, to Clark County. Accountability for Building 18 was transferred to the Atomic Energy Commission (currently DOE) and accountability for Building 40 (Radar Tower FPS-20) was transferred to the Federal Aviation Administration (FAA).

In 1975 Nellis Air Force Base reacquired by lease from Clark County, the use of Building 60, the Ground/Air Transmitter Receiver (GATR) facility and the associated 1.6998 acres.

All main buildings in the Operations Area are currently in use. The FAA operates the radar facility in Building 40. DOE maintains Building 18 and leases space to Nellis Air Force Base, and other government and private entities. Clark County leases all other buildings in the Operations Area to other government and private organizations. Improvements in the Operations Area not currently in use include four above-ground fuel storage tanks (three have not been used beneficially following Air Force disposal, one was used beneficially by Clark County), and four ground-mounted electrical transformers (three have not been used beneficially since Air Force disposal, one was used beneficially by the FAA).

Improvements in the Cantonment Area are used by Clark County Juvenile Court Services, Spring Mountain Youth Camp (SMYC). Buildings 5, and 44 have been removed, but the foundations are currently used for various functions.

Of the three septic tanks which comprise the sewage treatment system, Clark County SMYC uses the tank in the Carntonment Area (south of Building 42) and the tank in the Operations Area (northeast of Building 47), both of which discharge to the ground surface. The third septic tank (believed located east of Building 15, although not observed) likely serves most of the buildings in the Operations Area.

SMYC has been cited by the Nevada Division of Environmental Protection for numerous spill and discharge violations. Cleanup Order No. 051392W1, dated 13 May 1992, has been issued. Numerous violations cited include fuel spills, soil stains, and problems resulting from obsolete design such as discharge pipes directed to the ravine from the boiler room and auto shop floor drains. These violations are the result of SMYC activity.

An area presumed to be a shooting range located on the west side of a 500,000 gallon, water tank has not been used for this purpose subsequent to DOD disposal. The SMYC operations supervisor indicated that he had heard of someone having found in this area a mortar shell and various rounds of ammunition.

In 1979 Clark County acquired 85 acres in Patent from the Bureau of Land Management (BLM) for the use of SMYC. This 85-acre acquisition overlaps approximately 1/3 of the LVAFS site west of the Operations Area. In 1989 all BLM property in the area, including the LVAFS site property not yet patented by Clark County, was transferred from the BLM to the U.S. Forest Service.
