W. R. Grace and Company
WR Grace is an AWE facility for 1955-March 1, 2011 so workers are eligible to file Part B claims.
WR Grace has a Special Exposure Cohort which covers all workers with specific cancers and at least 250 days of employment for May 1, 1956 through January 31, 1958.
Processing of radioactive materials at W.R. Grace began in July 1955 when Rare Earths, Inc. (W.R. Grace's predecessor) entered into a contract with the Atomic Energy Commission to extract thorium and rare earths from naturally-occurring monazite sands. In 1956, the Atomic Energy Commission contract and Rare Earths' license to possess, transfer, and use radioactive thorium were transferred to W.R. Grace & Company. The facility where thorium processing took place (Building 23) operated until late spring of 1957, when W.R. Grace and the Atomic Energy Commission agreed to terminate the contract, effective January 31, 1958.
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.
DOE's Legacy Management has a W. R. Grace website since it was considered for FUSRAP.
