 Diamond Magnesium, Painesville Ohio-Deleted

 

Diamond MagnesiumDiamond Magnesium

Diamond Magnesium was an AWE facility for 1951-October 2009 but has been removed from EEOICPA coverage.

The Painesville Site was formerly a magnesium production facility, owned by the Diamond Magnesium Company. In 1951, 1952 and 1953, Diamond Magnesium received approximately 1650 tons of radioactively contaminated scrap steel from the Lake Ontario Ordnance Works, to be used to control chlorine emissions during the magnesium production process.

Although this site was designated as part of the Formerly Utilized Site Remediation Action Program (FUSRAP) in 1992, no work under this program occurred prior to its transfer to the Army Corp.

During the period of residual contamination, as designated by the National Institute for Occupational Safety and Health and as noted in the dates above, employees of subsequent owners and operators of this facility are also covered under the Energy Employees Occupational Illness Compensation Program Act.        

In the early 1940s, the Defense Plant Corporation constructed a magnesium production facility on the Painesville site, which was owned by the Diamond Magnesium Company. The AEC provided the site with 800 tons of radioactively-contaminated scrap steel which was used to control chlorine emissions during the magnesium production. Storage of this scrap metal radioactively-contaminated soil was at the Painesville site.

The Painesville Site is located in Painesville, Ohio, approximately 22 miles northeast of Cleveland. Painesville had an operational magnesium production facility on the grounds, operated by the Diamond Magnesium Company in the 1940s. In the 1950s the Atomic Energy Commission (AEC), a predecessor agency to the US Department of Energy, shipped radioactively contaminated scrap steel to the Painesville site for use in their magnesium production processes. Residual radiation from the scraps contaminated the soil at the site with uranium, radium and thorium.
