Site 2 - New Fuel Farm The New Fuel Farm, Site 2, is located in the northwest portion of NAS-Fallon and was constructed in 1957 to replace the original "Old Fuel Farm". The site currently has the capacity to store approximately 3,320,000 gallons of fuel (3,300,500 gal of JP-8, 12,000 gal of mogas, and 8,000 gal of diesel). In 1986 routine construction work was being conducted within the fuel farm and resulted in free product draining into the excavation. A total of 14 wells were installed in 1987 to characterize the extent of the contamination within the New Fuel Farm. In 1988 a Preliminary Assessment of NAS Fallon was conducted. This assessment identified additional areas of potential soil and groundwater contamination within the New Fuel Farm fenced area. These included tank bottom disposal area, weed control area, and tanker truck/vehicle parking area. Additional work consisted of the removal of two 50,000-gallon underground storage tanks, installation of a limited free product recovery system and assessments of the weed control and tanker/vehicle parking areas. The sampling of the weed control and parking areas indicated that the soils and groundwater had not been impacted above current action levels. Site 3 - Hangar 1 Area (formerly Hangar 300 Area) The Hangar 1 Area is located in the west-central portion of NAS Fallon consists of several separate areas: the north and south disposal areas, bowser disposal area, O/WS area, ground-support equipment area, and the Wells air start building area. Because of their relative proximity to each other, the areas are grouped together as a single site. Suspected contamination at each site is generally a result of the disposal of aircraft and vehicle maintenance wastes to unpaved ground surfaces. Site Status - 2001 The Navy has completed a "Comparison of Groundwater Alternatives Report" and "Assessment of Intrinsic Remediation" dated March 2001 that included Site 2. These reports and recommendations have been reviewed by NDEP. NDEP has tentatively approved of intrinsic monitoring for the limited dissolved plume upon receipt and approval of a increase/more aggressive free product recovery system and a monitoring plan to monitor the dissolved phase hydrocarbons and natural degradation plan.
