Harshaw Chemical

Harshaw Chemical is an AWE facility for 1942-March 1, 2011 so workers are eligible to file for Part B claims.

Harshaw has a Special Exposure Cohort for all workers with with specific cancers and at least 250 days employment from August 14, 1942-November 30, 1049.

Harshaw Chemical of Cleveland, Ohio refined black oxide and sodium diuranate to orange oxide and then to brown oxide for the Manhattan Project during World War II. The final result was a "green salt", which the Manhattan Project used to produce uranium hexafluoride for enrichment into weapons grade fuel for nuclear weapons at the gaseous diffusion plants. Harshaw also produced uranium hexafloride during the war and this production activity was expanded in 1947. Harshaw production was reduced in 1951 and by May of 1953 the green salt plant was dismantled and the hexafluoride plant was placed on standby. The contract for removal of AEC equipment continued until September 30, 1955. This designation is limited to the Harshaw facility located at 1000 Harvard Avenue, Cleveland and generally referred to as the Harvard-Denison plant.

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.

Harshaw Chemical Company was acquired by Kewaunee Oil Company in 1964. Kewaunee Oil was then acquired by the Gulf Oil Company in 1976. Kaiser Chemical Company acquired Harshaw interests in 1982.

The former Harshaw Chemical Company, encompassing 55 acres, is located at 1000 Harvard Avenue in Cleveland, Ohio, three miles south of downtown Cleveland. The site is located adjacent to the Cuyahoga River and Big Creek in an industrialized area in Cuyahoga County.  The Harshaw Chemical Company (HCC) conducted chemical and radiological research and production under contract to the Manhattan Engineer District (MED) and the Atomic Energy Commission (AEC) from 1942 through 1959. Numerous materials were produced by refining uranium oxide feed material.  Originally owned by the Harshaw, Fuller & Goodwin Company in 1905. HCC commercially manufactured chemical solvents, metal salts, fluorides, hydrofluoric acids, and other chemical products at the Harvard Avenue location. The HCC began production of chemical and radiological compounds for the MED in late 1942.
