The Parkersburg Site in West Virginia contains an engineered disposal cell for radioactive waste from a former uranium mill. Major long-term stewardship activities include monitoring the disposal cell, restricting access, inspecting fencing and signs, and monitoring groundwater. The 6-hectare site has been monitored since 1983, with disposal of approximately 15,300 cubic meters of waste in the cell. Annual costs average around $16,400, with higher costs every 5 years for groundwater monitoring. The site will remain under long-term stewardship by the DOE indefinitely to ensure the integrity of the disposal cell.

subsequently deteriorated and leaked, resulting in soil
contamination. Approximately 3,000 drums of ore,
waste, and contaminated soil were disposed of offsite
in 1968. The remaining contamination was consolidated in an onsite engineered disposal cell. The grasscovered, gently sloping disposal cell occupies an area of approximately five hectares (12 acres) and rises to a
maximum height of approximately three meters (nine feet). American Metals Climax (AMAX) completed
remediation of the site in 1983.
The DOE Grand Junction Office is the present landlord at the site. The current mission for the Parkersburg Site
is maintaining and monitoring the onsite disposal cell. The historic mission of the site was to produce zirconium
metal for use in the construction of nuclear reactors for the U.S. Navy. The Carborundum Company developed
the Parkersburg site in 1957. AMAX assumed ownership of the plant in 1967, becoming the U.S. Nuclear
Regulatory Commission (NRC) licensee to process and possess radioactive ores and waste materials at this
location. According to the provisions of the Nuclear Waste Policy Act of 1982 (NWPA), the site was transferred
to DOE in 1994 for long-term monitoring and maintenance.
1.2
Site Cleanup and Accomplishments
Remediation ofthe site was completed by AMAX in 1983, which consisted of demolishing site structures and
burying contaminated structural materials, radioactive soils, and pyrophoric materials in the onsite engineered
disposal cell. Less than 15,300 cubic meters (20,000 cubic yards) of waste are contained in the disposal cell.
The precise volume of the waste is unknown since the design drawings of the cell were not provided to DOE at
the time of site transfer. The disposal cell is capped with clay and revegetated with grasses to prevent erosion.
To date, no groundwater contamination has been detected at the site. Groundwater samples determined that
groundwater complies with the State of West Virginia's groundwater standards and with the Federal Safe
Drinking Water Act.

Long-Term Stewardship Activities
Long-term stewardship activities at the Parkersburg Site began in 1983, prior to the site's transfer to DOE. The
site was transferred to DOE 1994, and DOE is now responsible for conducting all long-term stewardship
activities at the site. A two-meter (six-foot) tall locked fence surrounds the site, controlling access to the disposal
cell. To prevent human exposure to the buried waste, no drilling or other intrusive activities are allowed on the
property, except for installation of additional groundwater monitoring wells.
Boundary monuments define the six corners of the legal boundary of the site property. Warning signs are placed
at intervals along the security fence around the site perimeter. Six groundwater monitoring wells are located
around the perimeter of the stabilization mound and inside the security fence. A total of six wells are located
in the north (three wells), west-central, south-central, and northeast parts of the site. DOE's responsibility for
the safety and integrity of the Parkersburg site will continue in perpetuity.
Site records are kept in permanent storage at the DOE Grand Junction Office in Colorado. The types of records
maintained include site characterization data, remedial action design information, the radiological assessment,
long-term monitoring plans, annual inspection reports, and current and historic monitoring data.

filled barrier trench was constructed around the perimeter of
the stabilization mound to protect it from horizontal
movement of offsite shallow groundwater. In addition, a shallow drainage furrow was constructed to channel
water away from the mound.
Long-term stewardship activities include annual site inspections of the disposal cell and minor maintenance
activities, such as fence repairs, sign replacement, and cap maintenance. DOE will perform long-term
stewardship activities at the disposal cell, including access restrictions, in perpetuity.
Groundwater
Site characterization by DOE in 1994 showed that groundwater beneath the site was not contaminated. As a best
management practice, DOE monitors groundwater at five-year intervals to ensure the integrity of the disposal
cell in perpetuity.
2.3
Regulatory Regime
Long-term stewardship activities at the Parkersburg Site is governed by several regulations, including the Nuclear
Waste Policy Act (NWPA), Section 151(C); the Atomic Energy Act of 1954, as amended; and the National
Environmental Policy Act of 1969, as amended. Section 151(C) of the NWPA, required that if low-level
radioactive waste is the result of a licensed activity to recover zirconium, hafnium, and rare earth metals from
source material, DOE shall assume title and custody of the site if requested by the site owner.
The need for continued groundwater monitoring at the Parkersburg Site was evaluated in accordance with DOE
Orders 5440.1E, "National Environmental Policy Act (NEPA) Compliance Program," and 5400.1, "General
Environmental Protection Program."
2.4
Assumptions and Uncertainties
DOE assumes that groundwater monitoring will continue to occur at five-year intervals in perpetuity.
Because the site has been monitored for almost 20 years, the long-term stewardship activities at the site are well
known and are not expected to change dramatically. Sound scope and cost estimates for the long-term
stewardship activities at the site have been developed.

ESTIMATED LONG-TERM STEWARDSHIP COSTS
AMAX made a one-time payment of $230,000 to the U.S. Treasury in January 1994, as required under the
NWPA to cover the costs associated with long-term stewardship activities at the site. Long-term stewardship
costs for the site are relatively constant, with slight spikes every fifth year due to costs from groundwater
monitoring.
