Abstract:  Fort George G. Meade (FGGM) is located in Anne Arundel County, Maryland. Prior to Base Closure and Realignment (BRAC), FGGM occupied 13,596 acres of land in the northwest corner of Anne Arundel County. It is bounded on the north by the Baltimore-Washington Parkway and by the Patuxent River to the south.

The facility was authorized by Congress in 1917 as a training cantonment for troops during World War I. During the 1940s, the facility underwent widespread growth to accommodate several regiments who moved their base of operations to FGGM, including the Second U.S. Army and the Eleventh Cavalry. Tipton Army Airfield was completed in 1963, replacing a small airstrip that has been in operation since 1928.

In 1988, BRAC mandated the closure and/or realignment of approximately 9,000 acres, encompassing then southernmost two-thirds of the installation. In 1991, the Army transferred 7,600 of the 9,000 acres to the Department of Interior's Patuxent Research Refuge (PRR), formerly known as the Patuxent Wildlife Research Center (PWRC). A second land transfer of approximately 500 acres to the PRR took place in January 1993.

The Tipton Airfield Area parcel, comprised of one Inactive Landfill, the Tipton Airfield, the airfield infrastructure and adjacent areas, covers approximately 366 acres of the remaining property. The helicopter hangar area is located at the northwest corner of the airfield, adjacent to the Little Patuxent River. The former fire training area is located off Airfield Road and is north of the airfield and east of the helicopter hangar.

FGGM was placed on the National Priorities List (NPL) in July 1998.

The Tipton Airfield Operable Unit consists of the following Areas Requiring Environmental Evaluation (AREEs): AREE 2 (Helicopter Hangar Area); AREE 4 (Fire Training Area); and AREE 12 (Inactive Landfill Number 3).

AREE 2 covers approximately 5 acres and includes the Helicopter Hangar building and adjacent areas located at the northwest corner of the airfield. Typical activities in this area included washing, disassembly, repair, and painting of aircraft. In addition to the use of fuels such as aviation and diesel fuel, other materials that were typically used, handled or stored included hydraulic and lubricating oils, detergents, and solvents. The hangar was cleared and taken out of service when it was decommissioned in early 1996.

AREE 4 covers approximately two acres and was constructed around 1979 for training purposes by the Fort Meade Fire Department. Both the fire-training pit and the oil-water separator used in draining the training pit were removed in 1998.

AREE 12 was initially used as a sand borrow area. During the late 1940s and 1950s, the area was used as a sanitary and leaf-dump landfill. The Tipton Army Airfield was constructed over the fill area in 1963. The airfield construction plans indicate that landfill materials were removed from beneath all runway construction areas for structural reasons. However, landfilled materials are still present in areas subjacent to the runways.

A Record of Decision addressing OU1 was completed in December 1998.
Remedy:  No further action is necessary at the Tipton Airfield Area Operable Unit (TAAOU) to protect human health and the environment. Under the no further action alternative, no remedial action will be taken at the TAAOU based upon both the current level of risk posed by contamination at the TAAOU and the protectiveness provided by prior removal
actions. This is the final response action for the TAAOU.
