The Tobyhanna Army Depot (TYAD) is located in Monroe County, Pennsylvania, approximately 15 miles southeast of Scranton, Pennsylvania, adjacent to the Village of Tobyhanna. Although the name and mission have changed since its inception in 1909, TYAD has always been a government-owned and government-operated facility. TYAD was used for field artillery training and ordnance storage during World War I. After several years of inactivity, TYAD was used as a training, equipment storage, and detention center during World War II. TYAD was again deactivated until construction of the current installation in the early 1950s. TYAD now encompasses approximately 1,293 acres (2.2 square miles). As a communications-electronics maintenance and supply depot, the current function of TYAD is the design, fabrication, repair, and modification of wide range of communications and electronics systems.Operable Unit 3 (OU 3) is comprised of Area of Concern (AOC) 37 Building 10-C, AOC 38 Building S-90. Both buildings 10-C and S-90 were ┬┐closed┬┐ as hazardous waste storage facilities in accordance with the permit issued to TYAD. In the spring of 1987, EPA performed a preliminary review and visual site inspection to identify potential Solid Waste Management Units (SWMUs) and other areas of potential concern at TYAD. Two of the SWMUs identified were buildings 10-C and S-90. In early 1990, an evaluation of SWMUs at TYAD were conducted. It was determined that no additional environmental investigations were warranted at these buildings and several other SWMUs due to the low probability that releases would jeopardize human health and the environment.
Remedy:  No Further Action is the selected remedy for OU 3. The following closure activities were performed in the spring of 1993: removal of hazardous wastes from buildings; inspection of building interiors; vacuuming of walls and floors; decontamination of buildings; sampling of building interiors and exteriors; performance of a risk assessment; and certification of closure in accordance with the permit.
