About the Guterl Steel Site

Guterl Steel Site


The former Simonds Saw and Steel Company, located in Lockport, New York, was contracted by the Atomic Energy Commission to conduct work in support of the Nation's early atomic energy and weapons program. Between 1948 and 1956 the facility was used for foundry work and rolling mill operations on over 25-million pounds of uranium metals and over 30-thousand pounds of thorium metals. Simonds Saw and Steel was sold to Wallace and Murray, and then sold to Guterl Specialty Steel Corporation. In March 1984 Allegheny International (now Allegheny Ludlum Corporation) purchased the entire site with the exception of those areas that had been used during the AEC activities.

The U.S. Army Corps of Engineers (USACE) is investigating the nature and extent of radiological contamination at the Guterl Steel Site (formerly Simonds Saw and Steel site) in the city of Lockport, New York. The site is located about 20 miles northeast of Buffalo and is bordered by Route 93 to the west, Route 31 to the north, Ohio Street and the Erie Barge Canal to the south and east. The Remedial Investigation characterizing radiological contamination at the Guterl Specialty Steel Site was recently completed and the report is available in the Reports section of this Web page.

During the Remedial Investigation the Corps of Engineers reviewed historical information and coordinated with state, county and local agencies, and stakeholders. Project specific goals and data quality objectives were established and a data gap analysis was completed. Data quality assurance and control measures were developed for sampling of site surface soil, subsurface soil, groundwater, sediments, surface water, and building media. Sampling and associated data gathering activities were completed in December 2007. Independent laboratory analytical data was used to define the nature and extent, and quantity of radiological contamination and to evaluate the potential risk to human health and the environment from the contamination.

Also completed during the investigation was the development of a groundwater model, preparing a fate, transport and exposure analysis, performing a baseline risk assessment and evaluating legally applicable or relevant and appropriate requirements (ARARs).

The US Army Corps of Engineers Buffalo District welcomes your input at any time. Our goal is to offer timely and meaningful opportunities for public input to our projects and to promote the dissemination of project information to the community. Public involvement activities complement the Corps' mission to address environmental contamination at the Guterl Site from past Manhattan Engineer District and Atomic Energy Commission activities.
