*Site Description:
The former Superior Steel Site is located in an industrial complex at 500 Superior Street in Scott Township, Allegheny County, Pennsylvania, (latitude 40.398569, longitude – 80.0096351) about 8 km (5 mi) southwest of downtown Pittsburgh. The Superior Steel site is located in Environmental Protection Agency (EPA) Region 3. The 25-acre site originally was occupied solely by the Superior Steel Company and now consists of several separately owned manufacturing, storage, and office buildings. The site is bounded on the north, west, and south by Chartiers Creek and on the east by Superior Street. The building that housed the uranium processing facilities (Building Complex Number 23) is now owned by Superbolt, Inc., a manufacturer of mechanical stud and bolt tensioners.
Superbolt Building Complex Number 23 consists of five interconnected steel-frame warehouses with metal roofs with corrugated steel siding. The floor construction varies from area to area and is a combination of poured concrete, brick, and bare earth. The building has a few windows, several garage-type doors, some standard door entrances, and various roof ventilator fans. Superior Steel used three of the five areas in Building 23 to process AEC-related material. Superbolt Inc. had previously leased the potentially contaminated areas to other businesses for use as storage space and limited light industrial activity. However, Superbolt Inc., discontinued this once the NRC identified residual radioactivity in Building 23. On August 29, 2006 during a site visit to the former SSC complex, representatives from Superbolt Inc. indicated that the northern third of Bldg. 23B is leased to a trucking company. This industrial complex, including Building 23, sustained extensive flood damage on September 18, 2004, when a discharge of 15,900 cubic feet per second occurred on Chartiers Creek (NRC 2006).
Superior Steel Co. is listed as an Atomic Weapons Employer (AWE) site under the EEOICPA.
