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.

Site Updates
February 2009
An investigation, funded by AK Steel, is underway. The investigation results will identify the types and amounts of contamination in the soil, sediment (mud), surface water and ground water (underground water) on and near the former industrial site. To accomplish this, extensive sampling of those areas as well as the site's former coke production facility was done last summer.
The Great Miami River shoreline was also studied last summer in response to community concerns. That information is still being evaluated. The results should be available this summer.
Another study was also done by AK Steel last spring and summer to get a better idea of how far the contamination may have spread. As part of that study, more soil and ground-water samples were collected and are being analyzed for many contaminants including metals, PCBs and PAHs. At that time, more monitoring wells were also installed. EPA is reviewing the company's draft versions of documents called the human health risk assessment and remedial investigation report, which explain what was found. AK Steel is expected to complete them this summer. The "feasibility study," which is an important document that outlines possible cleanup options, will follow in spring 2010.
A decision on how to clean up the site is expected by summer 2010. But first, 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.
