Illinois (FUSRAP Site)

22.2.

The only currently active Hlinois site within the Formerly Utilized Sites Remedial Action Program (FUSRAP) is
Madison. The three completed sites in Hlinois are Granite City Steel, National Guard Armory, and University of
Chicago. They are summarized in the overview of the FUSRAP program presented in the Tennessee section of this
report. FUSRAP was established in 1974 under the provisions of the Atomic Energy Act to identify, investigate, and
clean up or otherwise control previously decontaminated Manhattan Engineer District and Atomic Energy
Commission sites, together with other sites assigned to the U.S. Department of Energy by Congress, where residual
radioactive contamination exceeds current guidelines.

FUSRAP encompasses 46 sites in 14 states and is funded through the Oak Ridge Operations Office. For a general
discussion of FUSRAP and associated costs, see the overview of the program presented in-the Tennessee section of
this report. All costs for waste management activities, program management, and relevant landlord activities
attributable to the Department of Energy are provided for within the scope of environmental restoration. There are
no FUSRAP sites with either current or planned nuclear material and facility stabilization activity needs. Funding
Sor all sites is 100 percent nondefense.

MADISON

The Madison site. {formerly Dow Chemical Company plant) is located at College and Weaver Streets in Madison,
Illinois, across the Mississippi River from St. Louis, Missouri. The site consists of a large, multisectional complex of
10 interconnecting buildings with a total area under roof of approximately 130,000 square meters (1.4 million
square feet). The site covers approximately 300 hectares (735 acres).

FACILITY MISSION -

Lowlevel radioactive contamination, which is estimated at 7.5 cubic meters (10 cubic yards), found in dust on roof
support beams at the Madison site originated ftom uranium extrusion and rod-straightening work conducted by the
Dow Metal Products Division of Dow Chemical Company during the 1950s and 1960s. Dow operated under _
subcontract to Mallinckrodt Chemical Company, a prime Atomic Energy Commission contractor, and supplied
materials (chemicals, induction heating equipment, and magnesium metal products) and services under purchase orders
issued by Mallinckrodt. The site was included in FUSRAP in 1992. The Department of Energy's present objective at
the site is to conduct environmental restoration activities to eliminate, reduce, or otherwise mitigate the potential for
exposure to radioactive contaminants.

SETE MAP

‘Uranium238 and thorium232 were the primary contaminants detected at concentrations exceeding guidelines during a
1989 radiological survey. The contamination was found in dust from overhead beams in Building 6, where the uranium
extrnsion and rodstraightening work occurred. Building 6 is a large multistory metal building with a concrete floor.
‘The potential for contaminant transport is mainly through airborue particles. Potential exposure pathways are
inhalation and ingestion of exposed radioactive contaminants. The site is classified as a lowpriority site based on its

. inaccessibility and the limited extent of the residual contamination. Because the radioactive contamination is localized
and limited in extent, it is highly unlikely that, under current nse, an individual working in or frequenting these remote
areas would receive significant radiation exposure. However, additional scoping and survey measurements and
sampling are recommended to further define the extent of indoor uranium contamination southward to Building 4 and
northward further into Building 6. Under current use conditions, there is no significant exposure risk to site workers or
the general public.

FUTURE USE

‘The site will be released for use with no radiological restrictions after remedial action is complete. This report assumes
that the property will continue to be used for industrial purposes. .

ENVIRONMENTAL RESTORATION

Environmental restoration of the Madison site will include removing a total of 7.5 cubic meters (10 cubic yards) of
Jow-level waste, 1.5 cubic meters (2 cubic yards) of contaminated dust, and 6 cubic meters (8 cubic yards) of
workrelated waste, including worker uniforms and personal protective equipment. Because the site is heavily involved
in production operations for metal extrusion and machining, the present owner, Spectrulite Consortinm, is expected to
provide a window of opportunity within the next decade during which production operations can be inferrupted tong
enough to allow the Department of. Energy to remediate the property.

The environmental regulatory process will focus on compliance with National Environmental Policy Act requirements.
Key regulators include Environmental Protection Agency Region V, ‘the Ilinois Environmental | Protection 1 Agency, and
~~ “Yocal governments as appropriaic.

TASK

ASSESSMENT

Field investigations at the Madison site consisted of a radiological survey in 1989 and a site scoping visit in 1993. The
survey included gamma scanning of accessible floor and wall surfaces throughout the buildimg and on overhead beams:
collection and radiological analysis of indoor dust and debris; and determination of direct and removable betagamma
and alpha activity levels on overhead beam surfaces.

The walkover survey and sampling of dust from overhead beams identified uranium238 and thorium232 at
concentrations exceeding current guidelines. No additional sampling and monitoring of environmental media have
been conducted because the contamination is inside a building that is currently involved in daily production. However,
the site scoping visit found the overhead beams to be significantly more complex than originally thought, making
cleanup more challenging. During the radiological survey, smear samples were taken only on the lower sections of the
beam design, leaving large amounts of surfacé area unsurveyed. Conduit and piping that ran through the overheads
also are likely to be contaminated. The cleanup effort will require extensive scaffolding, and many areas are not easily
accessible.

The initial site designation report addresses assessments of radioactive contamination. Detailed characterization,
including sampling and analysis, will be conducted before cleanup begins.

REMEDIAL ACTION

Investigators believe that remedial action was conducted at the Madison site after two major production campaigns in
the late 1950s and early 1960s; however, no records providing details of the plant cleanup have been located.

The Department of Energy has not yet performed any remedial action at the site. The selection of a preferred cleanup
option will be based on results of the upcoming characterization, which will provide further information about the
nature and extent of contamination and site-specific waste management requirements.

The scenario used for the Baseline Environmental Management Report cost estimate assumes that the 7.5 cubic meters
(10 cubic yards) of low-level waste will be disposed of at an outofstate commercial disposal facility. The cleanup
approach is expected to be a streamlined removal action conducted under a Department of Energy FUSRAP-expedited
protocol that is frequently used for cleanup of small volumes of contamination within buildings where there is little
threat of contaminant release. °
