The site is fenced on the northern and eastern sides. The western side ofthe property adjoining Cloverleaf Drive is unfenced. The southern side of the property has a galvanized guard-rail adjoining an un-named tributary to Beaver Run. Residential neighborhoods are located adjacent to the property on its eastern and northern sides; and unoccupied fields are present on its western and southern sides. Kennametal owned and operated the facility until September 1992, when operations were terminated. The property was purchased by the Westmoreland County Food Bank on July 9, 1993. Westmoreland County Food Bank, a not-for-profit organization, presently operates a warehouse for canned and frozen foods, a kitchen, and offices at this location.

During the EPA site visit in 2009, overall site features remained the similar to the original configuration when the facility was owned by Kennametal. The facility consisted of a main building and three small outbuildings. No changes were made to the overall footprint of the building, which remains approximately 34,000 square feet in area. Equipment associated with a coolant system in the main building was removed and the refrigerant was recycled, according to the operations manager of Westmoreland County Food Bank. All of the equipment associated with the former Kennametal operations was removed before the food bank operations began.

Contaminants at this Facility

A variety of wastes, including isopropanol, petroleum naphtha, coolant, and hydraulic oil were generated at the facility. Spent oil and coolant, and all hazardous wastes were stored in drums within the main facility. During its operation, Kennametal generated ignitable wastes, such as petroleum naphtha and isopropanol. Nonhazardous wastes produced included ceramic powder, iron oxide sludge, coolant (commercial name Recool Gold), and hydraulic oil. Liquix Company of Carnegie, Pennsylvania removed 1,500 gallons of Recool Gold every six months. The ceramic powder used by the facility in the preparation of its cutting bits was subjected to the EP toxicity test and found to be nontoxic .

There appear to be no environmental impacts from Kennametal's operations.
