The Dayton Project is a DOE facility for July 14-1950 so workers are eligible to file for both Part B and Part E claims.
The Dayton Project is an SEC site. Atomic Weapons Employer employees who were monitored or should have been monitored for exposure to ionizing radiation while working at Monsanto Chemical Company Units I, III, or IV in Dayton, Ohio, for a number of work days aggregating at least 250 work days during the period from January 1, 1943, through December 31, 1949, or in combination with work days within the parameters established for one or more other classes of employees in the SEC.
In 1943, the Manhattan Engineer District (MED) began the Dayton Project to investigate the chemistry and metallurgy of polonium. Because Monsanto Chemical Company was already working with polonium, it was chosen as contractor for the project.
In 1943, the MED-contracted work was performed at Monsanto’s Nicholas Road location (Unit I). As the project expanded, it moved into an old building belonging to the Dayton school district at 1601 West First Street, and by October 1944 all operations had been transferred to this location from Unit I. This site became known as Unit III. In early 1944 it became apparent that the space at Unit III was also inadequate, so the U.S. Army Corps of Engineers used a judicial proceeding to obtain ownership of a building known as the former Runnymeade Playhouse in Oakwood and turned it over to Monsanto for its use on the Dayton Project. Monsanto operated a laboratory at this second location and referred to it as Unit IV. When project needs again increased beyond the combined capacity of Units III and IV, preparations were made to move the entire operation to the present-day Mound facility in Miamisburg, Ohio. Processing began at Mound in February 1949. By the end of 1950, after either decontamination or demolition, the AEC released its ownership interest in the properties back to the original owners.
Throughout the time period for this facility from 1943 through 1950, the potential for beryllium exposure existed at this site.
The Dayton Project in Dayton, Ohio began in 1943 to investigate the chemistry and metallurgy of polonium as part of the Manhattan Project. By 1946, it was apparent that a larger, more permanent facility was needed and work began on Mound Laboratory in Miamisburg Ohio. When Mound was completed the Dayton Project work transferred there and work at the Dayton Project locations ended in 1948. In 1944 the US government condemned and took possession of the Talbott family's Runnymede Playhouse in a Court Order by the US District Court, Southern District of Ohio Civil No. 319. The change of ownership was recorded in Montgomery County's deed book. The Court Order also dictated the terms of the cleanup that the government was required to perform on the property.
Workers at the Dayton Project now covered under Part E
EECAP's investigation into the Dayton Project has paid off! On March 6, 2012 the final step was completed in designating the Dayton Project a DOE site. This means that all workers at Units 1, 3, and 4 are covered for both Part B and Part E so these workers are eligible to file claims for illnesses caused by chemicals as well as radiation. The Dayton Daily News reported on this on March 6. EECAP sent out a press release on the issue.
EECAP has generated a partial list of chemicals at the Dayton Project. This list is taken from DOE documents which prove the chemical was on site. Please contact EECAP for further information. We will be happy to supply you with copies of the documents to use in your claim. EECAP will also be supplying DOL with this list and copies of the documents within a short time. We will be adding to this list as time permits.
Many thanks to the good people at the Mound Museum in Miamisburg Ohio for the bulk of the Dayton Project documents.

DOE Legacy Management has a webpage on the Dayton Project's FUSRAP status.
DOL lists Dayton Project statistics two ways. For the years where just AWE workers were covered it is listed as Monsanto Chemical. They also list statistics for the Dayton Project. DOL also has a Dayton Project Site Exposure Matrix.
The EPA discusses the Dayton Project and gives the locations of the various units and their FUSRAP (Formerly Utilized Sites Remedial Action Program) status.
NIOSH provides statistics on dose reconstructions for the Dayton Project.
