The 122nd Tactical Fighter Wing, Indiana Air National Guard (ANG), is located in Allen County, Indiana, on the southwest side of the City of Fort Wayne. Baer Field Municipal Airport is located immediately west of the Base. South and east of the Base, the land is mostly agricultural, and commercial property lies to the north.
90 acres of land.
The 122nd Tactical Fighter Wing was established at Fort Wayne in 1954. Past Base operations that generated potentially hazardous materials include aircraft maintenance, weapons maintenance, liquid fuels management, fire fighting training, and vehicle maintenance. Waste oils, fuels, cleaners, solvents, and strippers were generated by these Base activities.

B. Environmental Issues
Site 1 - Former Fire Training Area
The Former Fire Training Area (FTA) is located in the extreme southern portion of the Base, south of Building 771 (the Hush House). The location of the former FTA was determined from field observations, interviews with Base personnel (including the former Base Fire Chief), and aerial photographs. The source of contamination at the former FTA is a burn area approximately 15 by 90 feet. The burn area was designed to contain fuel and waste oils used during fire fighting exercises with the construction of a berm on the western (downslope) side of the burn area. The berm was approximately 2 feet wide at its base, 1 foot high and rounded at the top, and extended the entire length of the burn area. The burn area was unlined. Prior to the commencement of each fire fighting exercise, the burn area was soaked with water. The water-soaked ground helped to reduce the extent of fuel migration into the ground.
The former FTA was used from 1963 to 1972 approximately 10 times a year. During each fire training exercise, approximately 50 to 60 gallons of fuel were used for a total of 500 to 600 gallons per year. Most of the fuel used was JP-4; a minimal amount of motor oil and aviation gasoline also was used.
After each fire training session, the burning fuel was extinguished by teams of personnel using a spray of water and foaming agent, which was directed to the northwest or southwest. Occasionally, this stream washed some of the fuel over the berm and downslope from the burn area.
After 1972, the ANG began dumping fill material (primarily native clay soils and some construction debris) over and around the former FTA. The area was continually filled and graded, eventually burying the former FTA under approximately 10 to 12 feet of fill.
Site 2 - Former Motor Pool
The former motor pool is located north of the munitions storage area. One underground fuel oil tank has been removed from this site and other tanks are suspected to be in the area. PCB contamination is also suspected in this area. This site was not investigated under the original site inspection and is currently being investigated under a site inspection workplan addendum. A residual hydrocarbon plume was found. Excavation of the material was not completed, as the contaminated material is adjacent to a restricted munitions storage area. Geophysical work is being planned to look for additional underground tanks.
Site 3 - Hazardous Waste Collection Area
The Hazardous Waste Collection Area (HWCA), located behind Building 760, is a 50-foot square gravel area enclosed by a wooden fence. The HWCA currently is used as a temporary storage area. Since 1954, waste oils, solvents, paints, and thinners from various shops have been collected and stored in drums at this location. Initially, the area was grassy; it was later graveled and fenced. Drums of waste oil, hydraulic oil, PD-680 solvent, paints, and thinners are stored on pallets on the gravel. A site visit during the Phase I SI kick-off meeting revealed that funnels were in the top of each drum, the gravel was stained, and there was a noticeable odor of oils and solvents. Prior to the start of Phase II, Base personnel moved most of the drums from the area to a central staging area at the Base. The drums were removed from the staging area by the Defense Reclamation and Maintenance Organization for appropriate disposal at an off-Base location.
Site 4 - POL Spill Area
The POL Spill Area is located in the northern portion of the Base, east of Building 356. In 1968, a malfunction in the POL system at Building 352 and the nearby pump house resulted in a spill of 5,000 to 5,300 gallons of JP-4 fuel. The spill flowed from the POL facility and ran eastward into the woods and into an open storm drainage ditch. Approximately 200,000 gallons of water were used to flush the JP-4 from the immediate POL area. The water and fuel were reportedly washed eastward into the surface drainage system and eventually into Harber Ditch, which is approximately 3,000 feet east of the Base. ANG personnel noted no vegetative damage in the woods after the spill (HMTC 1988).
