DEPARTMENT OF ENERGY
Floodplain Statement of Findings K-705 Water Intake Structure
Demolition at the Oak Ridge, TN K-25 Site
AGENCY: Department of Energy (DOE).
ACTION: Floodplain Statement of Findings.
-----------------------------------------------------------------------
SUMMARY: This is a Floodplain Statement of Findings K-705 Water Intake
Structure Demolition at the Oak Ridge K-25 Site, prepared in accordance
with 10 CFR Part 1022. DOE proposes to remove out-of-service equipment
and materials and demolish the K-705 water intake structure, a part of
the K-700 Powerhouse Area. DOE prepared a floodplain assessment
describing the effects, alternatives, and measures designed to avoid or
minimize potential harm to or within the affected floodplain. Portions
of the K-705 structure are located within the 100-year floodplain of
the Clinch River, located in Roane County, Tennessee. DOE will endeavor
to allow 15 days of public review after publication of the statement of
findings before implementing the proposed action.
FOR FURTHER INFORMATION CONTACT:
Information on the proposed action, including maps of potentially
disturbed floodplain area, is available from: Mr. Robert C. Sleeman,
Director, Environmental Restoration Division, Oak Ridge Operations
Office, U.S. Department of Energy, P.O. Box 2001, Oak Ridge, Tennessee

requirements is available from: Ms. Carol M. Borgstrom, Director,

SUPPLEMENTARY INFORMATION: This is a Floodplain Statement of Findings
for the K-705 Water Intake Structure Demolition at the Oak Ridge K-25
Site, prepared in accordance with 10 CFR Part 1022. A Notice of
Floodplain/Wetlands Involvement for Environmental Restoration and Waste
Management Activities at the DOE Oak Ridge Reservation was published in
the Federal Register and a floodplain assessment was prepared; no
wetlands [58 FR 51624 (October 4, 1993)] are involved in the proposed
action.
DOE is proposing to characterize the facility, perform waste
removal, and undertake demolition of the K-705 water intake structure.
The K-705 water intake structure consists of the water intake filter
wall, sidewalls, and a berm. The water intake filter wall is a metal
filtration wall that extends approximately 100 feet into the main
channel of the Clinch River and acts to screen water prior to intake.
The sidewalls are constructed of solid sheet metal piles and are
embedded into a berm. K-705 has been shutdown since the 1960s; it is
not currently being used or maintained and has reached a state of
significant deterioration. As a result, additional access control
measures are required to ensure personnel safety around the structure.
The purpose of the proposed action is to remove the potential for
adverse environmental, health, and safety impacts, including potential
hazards to navigation, that may result from the deteriorated facility.
The proposed action would involve facility characterization, removal of
all accessory materials, and demolition to grade level using the most
cost-effective method. Removal of K-705 would be conducted in
accordance with the removal methods described in the U.S. Army Corps of
Engineers Nationwide Wetlands Permit. Temporary disturbance of the
Floodplain may occur during the removal of the steel sidewalls of the
water intake filter wall from the river bank sediment if this specific
activity proved necessary. The temporary disturbance would last
approximately 2-3 weeks. If removal of the berm of the structure
protruding into the water was necessary, dust/debris-control procedures
would be applied during demolition. Best management practices would be
implemented to ensure that minimal disturbance to the 100-year
Floodplain would occur as a result of taking the proposed action.
The alternative to the proposed action is to take no action. The no
action alternative would mean that DOE would be unable to remove this
potentially adverse environmental, health, and safety impact.
On the basis of the Floodplain Assessment, DOE has determined that
the proposed action would not alter the storage capacity of the Clinch
River Floodplain or increase risks to individuals, property, or the
environment. The Floodplain Assessment was performed to assess the
potential hydrologic impacts of the proposed action. The Floodplain
Assessment addresses (1) the potential for alteration of the Clinch
River Floodplain as a result of the proposed action, (2) the increase
in water surface elevations during flood events, and (3) the potential
impacts of the proposed action on adjacent properties and the
environment. Results of the Floodplain Assessment indicate
inconsequential hydrologic impacts. Therefore, the proposed
characterization, waste removal, and demolition of the K-705 structure
would not affect the existing normal channel or 100-year Floodplain of
the Clinch River. The proposed action conforms to applicable State
Floodplain standards. DOE will endeavor to allow 15 days of public
review after publication of the Statement of Findings prior to
implementing the proposed action.
