Also Known As: Chapman Valve Manufacturing Co., Crane Co.
State: Massachusetts
Location: Indian Orchard
Time Period: AWE 1948-1949; Residual Radiation 1950-1994; DOE 1995 (remediation)
Facility Type: Atomic Weapons Employer, Department of Energy
Facility Description: Chapman Valve supplied valves to the MED and the AEC. In 1948, Chapman Valve machined uranium rods into slugs for the Brookhaven National Laboratory. Uranium slugs were used as reactor fuel. Chapman may also have conducted rolling operations on uranium metal in 1949. During the 1948 and 1949 time period, the Chapman Valve building located on Dean Street in Indian Orchard was part of the Chapman facility and not a distinct and separate location. Bechtel National, Inc., with Interstate Nuclear Services and Thermo Nutech as subcontractors, performed remediation in 1995 as part of the Formerly Utilized Site Remediation Action Program (FUSRAP)
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.
Chapman Valve is listed as an Atomic Weapons Employer (AWE) site and as a Department of Energy (DOE) site under the EEOICPA.
As of 03/15/2015, the total compensation paid under Parts B and E of the EEOICPA, including medical compensation, for workers suffering from the effects of having worked at Chapman Valve is $7,072,198.

*Site Description and History:
The Indian Orchard, Massachusetts, Site (formerly the Chapman Valve site) is located at 203 Hampshire Street in Indian Orchard, which is a suburb of Springfield, Massachusetts.
In 1948, Chapman Valve Manufacturing Company used one-third of Building 23, an area that measured approximately 60 feet by 200 feet and was separated from the remainder of the building by a fl oor-to-ceiling partition, to machine uranium rods for the Manhattan Engineer District. Uranium operations ended in November of that year, resulting in more than 27,000 pounds of metal scraps, oxides, and refuse on site. This material was removed several months after the contract was completed, and the building was decontaminated to standards in effect at that time.
The U.S. Department of Energy (DOE) conducted a radiological survey at the site in 1991. Survey results identified residual uranium contamination that exceeded DOE criteria on surfaces and in the west end of the building. As a result, DOE designated the site for remediation under the Formerly Utilized Sites Remedial Action Program (FUSRAP). DOE conducted site characterization in late 1994 and early 1995.
Remedial action of the Indian Orchard site began in July 1995 and consisted of brushing, scrubbing, and vacuuming to remove contaminated material. Remedial action was completed in August of that year, and a total of 20 cubic yards of low-level radioactive waste was shipped to a licensed disposal facility in Utah.
