Background

The Armco Hamilton site, 401 Augspurger Road, consists of about 252 acres divided between two pieces of property north and south of Augspurger Road in the village of New Miami, Ohio. This is about 1.5 miles northeast of downtown Hamilton, Butler County. A small unnamed tributary borders a closed, on-site landfill to the east and flows east to the Great Miami River.

The site is an inactive facility that produced iron for steel making. It began operations as a steel mill around 1900 and has changed ownership several times. Armco (American Rolling Mills Co.) purchased the site from the Hamilton Coke and Iron Co. in 1937. Today, heavy metals, benzene, PAHs and PCBs are the contaminants of concern. AK Steel Corp. was a general partner of Armco and is the current owner of the site. (more...)

Site Updates

March 2012

AK Steel is expected to complete additional soil and ground water sampling, according to EPA specifications, in summer 2012. In addition, several documents detailing AK Steel's findings should be deemed final in early 2013. These documents, which will be available for public review, include the human health risk assessment, baseline ecological risk assessment and remedial investigation report. All of the studies, funded by AK Steel, are necessary so the company will have the information needed to see how far the PCB, PAH and metals contamination may have spread. EPA will continue to oversee AK Steel's work.

Another important requirement called the feasibility study, which outlines possible cleanup options, is expected to follow in the fall of 2013. Before a decision on how to clean up the site is made, EPA will develop a "proposed plan" to explain its recommendations, hold a public comment period, and host a public meeting in the New Miami/ Hamilton area.

The results of this ongoing investigation will identify the types and amounts of contamination in the soil, sediment (mud), surface water and ground water (underground water supplies) on and near the former industrial site, coke production facility and the Great Miami River shoreline.
