The Kansas City
Plant was constructed in 1942 to build aircraft
engines for the Navy. After World War II, it was
used for storage. In 1949, the AEC asked the
Bendix Corporation to take over part of the
facility and it began manufacturing nonnuclear
components for nuclear weapons. Electrical,
electromechanical, mechanical, and plastic
components are manufactured or procured by this
facility.
In 1993, the Department of Energy
officially designated the Kansas City Plant as
the consolidated site for all nonnuclear
components for nuclear weapons.
As of 1996,
production activities at the site were still
occurring and expected to continue indefinitely.
Throughout the course of its operations, the
potential for beryllium exposure existed at this
site, due to beryllium use, residual
contamination, and decontamination activities.
The Mallinckrodt
Chemical Company conducted uranium milling and
refining operations under contracts with the
Manhattan Engineer District and the Atomic
Energy Commission at the St. Louis Downtown Site
in Missouri. Mallinckrodt transported process
residues to the St. Louis Airport Site (also in
Missouri) for storage until the Commercial
Discount Corporation of Chicago purchased them
in 1967; Commercial Discount transported the
residues to the Latty Avenue Properties for
storage and processing. This material was sold
to the Cotter Corporation in 1969 and was dried
and shipped to their facilities in Canon City,
Colorado. By 1974, most of the material had been
sold and removed from the Latty Avenue
Properties, leaving only residual contamination.
The 1984-1986 work was performed under the
Bechtel National Inc. (BNI) environmental
remediation umbrella contract for the DOE.
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.
From 1942 to 1957,
Mallinckrodt Chemical Company conducted a
variety of milling and recovery operations with
uranium chemical compounds at the St. Louis
Downtown Site, also known as the Destrehan
Street Plant. The plant refined uranium ore,
ultimately producing uranium metal. The
activities supported research, development, and
production programs for the national defense
program. By 1957, the Mallinckrodt Chemical
Company had processed more than 45,000 metric
tons (50,000 tons) of natural uranium products
at its facilities. During closeout of operations
in 1957, government-owned buildings were either
dismantled or transferred to Mallinckrodt as
part of a settlement. Decontamination work
continued to 1962 when the plant was released
back to Mallinckrodt.
This listing of the
Mallinckrodt Chemical Works (MCW), is intended
to cover the entire area bounded in part by
North* Broadway, Angelroot Street, and Salisbury
Street. Destrehan Street runs through the middle
of the entire area and is a common way to
reference the plant, but is by no means the only
valid building address. Many buildings are also
on Mallinckrodt Street. Coverage includes, but
is not limited, to the Main Plant, Plant 4,
Plant 6, Plant 6e and Plant 7.
Throughout the
course of its operations, the potential for
beryllium exposure existed at this site.
*The
original address for some buildings would have
been Broadway Street. Today, these same
buildings have the address of North Broadway
Street.
The Medart Company
manufactured steel mill machining equipment
which was useful in uranium processing. In 1952,
Medart conducted broaching machine and arbor
tests turning uranium for the National Lead
Company of Ohio (Fernald). According to a former
Medart employee, the bar turning machine was
eventually shipped to Fernald for use at the
Feed Materials Production Center.
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.
The Roger Iron Company conducted a test operation involving crushing of a dolomite c-liner for the AEC. The liner had trace amounts of uranium and magnesium fluoride. The test involved four individuals, including two employees of National Lead of Ohio (Fernald). NLO also monitored the air during the time of the test.
The Spencer Chemical
Company is no longer covered under EEOICPA.
Before it was removed from the program 24 Part B
claims had been filed with 4 of these paid.
Spencer had previously been designated as an AWE
facility from 1941-1945 or 1958-1963.
The
Manhattan Engineer District temporarily stored
approximately 2000 drums of pitchblende ores,
which contained uranium, at the Seneca Army
depot.
The Manhattan Engineer District (MED) began utilizing the St. Louis Airport Storage Site (SLAPS) in 1946 as a place to store residues from the Mallinckrodt Chemical Works. The MED acquired title to the property on January 3, 1947. In 1973 the property was transferred back to the city of St. Louis. Then in 1984, through the Energy and Water Development Appropriations Act (Public Law 98-3060) the property was returned to the Department of Energy until 1997 when Congress transferred it to the U.S. Army Corps of Engineers.
The Tyson Valley Powder Farm was a storage site for radioactive materials in the late 1940s. Records show, for example, that at the end of 1946, 206,110 pounds of uranium metal were stored at this location for the Manhattan Engineer District.
The United Nuclear
Corporation in Hematite, Missouri, processed
unirradiated uranium scrap for the AEC,
recovering enriched uranium from it for use in
the nuclear weapons complex. Mallinckrodt
Chemical Works owned the Hematite plant until
1961.
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 1955, the U.S.
Department of the Army (Army) transferred 217
acres of what had been the Weldon Springs
Ordnance Works to the U.S. Atomic Energy
Commission (AEC) for construction of a uranium
feed materials plant. The AEC constructed the
Weldon Spring Uranium Feed Materials Plant at
this location and contracted with the
Mallinckrodt Chemical Company to operate the
plant starting in June 1957. The plant was used
for uranium refining activities in support of
the national defense program. The AEC closed the
plant in December 1966 after deciding it was
obsolete.
After closing the plant, the AEC
transferred the plant and the land back to the
Army on December 31, 1967. On October 1, 1985,
custody of the chemical plant was retransferred
from the Army back to the DOE, which was given
responsibility for remediation of the plant.
The surface decontamination of the plant was
completed in October 2002.
In 1958, the U.S.
Atomic Energy Commission (AEC) acquired title
from the U.S. Department of the Army (Army) to
an inactive quarry that had been on the Weldon
Springs Ordnance Works land. The quarry was used
by the AEC as a dumping ground for chemical and
radiological waste products, including the
demolished Destrehan Street Plant in St. Louis.
Surface decontamination of the quarry was
completed in October 2002.
In 1955 the U.S.
Department of the Army (Army) transferred 217
acres of what had been the Weldon Springs
Ordnance Works to the U.S. Atomic Energy
Commission (AEC) to construct a uranium feed
materials plant. In addition to the plant, the
AEC also constructed four raffinate pits
adjacent to the plant between 1958 and 1964. The
pits were used as collection points and settling
basins for chemical and radioactive waste
streams coming from the plant.
After closing
the plant (including the associated raffinate
pits) in December 1966, the AEC transferred the
land back to the Army, but retained ownership
and control of the wastes in the raffinate pits.
On October 1, 1985, the land was retransferred
from the Army back to the DOE, which was given
responsibility for remediation of the pits.
Surface decontamination of the pits was
completed in October 2002.
