DEPARTMENT OF ENERGY

 

Notice of Floodplain Involvement for the Proposed East Fork 
Poplar Creek Flow Management Project at the Oak Ridge Reservation, Oak 
Ridge, TN

AGENCY: Department of Energy (DOE).

ACTION: Notice of floodplain involvement.

-----------------------------------------------------------------------

SUMMARY: DOE proposes to install an energy dissipation chamber and a 
raw water line in the Y-12 Plant within the East Fork Poplar Creek 
(EFPC) floodplain which is located in Anderson County, in the city of 
Oak Ridge, Tennessee. In accordance with 10 Code of Federal Regulations 
(CFR), part 1022, DOE will prepare a Floodplain Assessment and perform 
this proposed action in a manner so as to avoid or minimize potential 
harm to or within the affected floodplain.

DATES: Comments are due to the address below no later than March 29, 
1994.

ADDRESSES: Comments should be addressed to: R. J. Spence, Manager, DOE 
Y-12 Site Office, U.S. Department of Energy, Oak Ridge Operations 
Office, Post Office Box 2001, Oak Ridge, Tennessee 37831.

FOR FURTHER INFORMATION ON THIS PROPOSED ACTION, INCLUDING A LOCATION 
MAP, CONTACT:Susan D. Morris, DP-813, U.S. Department of Energy, Y-12 
Site Office, Post Office Box 2001, Oak Ridge, Tennessee 37831, 615-576-
3545 (telephone), 615-576-8019 (fascimile).

FOR FURTHER INFORMATION ON GENERAL DOE FLOODPLAIN/WETLAND ENVIRONMENTAL 
REVIEW REQUIREMENTS, CONTACT: Carol M. Borgstrom, Director, Office of 
NEPA Oversight, EH-25, U.S. Department of Energy, 1000 Independence 
Avenue, SW., Washington, DC. 20585,202-586-4600 or 800-472-2756

SUPPLEMENTARY INFORMATION: DOE proposes to install a concrete box with 
2 weirs (obstructions placed in a stream, diverting water for measuring 
the rate of flow) and a raw water line to manage the flow of the EFPC. 
The action would take place at the headwaters of the creek, which are 
located within the boundaries of the Y-12 Plant. The open box would be 
approximately 12 by 14 feet and emplaced at the edge of the creek bank 
to allow for proper diffusion and mixing of the added water with creek 
headwaters. Additional water would be provided by extending the 
existing raw water line from the Clinch River. As part of the proposed 
action, a Best Management Practices Plan will be prepared to identify 
the necessary steps to minimize potential impacts to the creek.
    The addition of Clinch River water to the creek is required by the 
Tennessee Department of Environment and Conservation in order to 
guarantee a minimum base flow as the limitations established in the Y-
12 Plant National Pollutant Discharge Elimination System permit are 
based on management of the flow in the EFPC. Additional water will not 
be added when the flow in the creek is above this established minimum 
flow, such as during storm events.
    In accordance with DOE regulations, ``Compliance with Floodplains/
Wetlands Environmental Review Requirements,'' 10 CFR part 1022, DOE 
will prepare a Floodplain Assessment for this proposed DOE action. 
After DOE issues the assessment, a Floodplain Statement of Findings 
will be published in the Federal Register.

    Issued in Washington, DC, on this 7th day of March 1994.
Eugene G. Grewis,
Associate Deputy Assistant Secretary for Military Application, Defense 
Programs.
