Withdrawal of the Notice of Intent To Prepare a Draft
Environmental Impact Statement for the Dam Safety Modification Study
Report for Center Hill Dam, DeKalb County, Tennessee
AGENCY: U.S. Army Corps of Engineers, DoD.
ACTION: Notice of Intent; withdrawal.
-----------------------------------------------------------------------
SUMMARY: The U.S. Army Corps of Engineers, Nashville District (USACE),
is issuing this notice to inform Federal, State, local governmental
agencies, and the public that USACE is withdrawing the Notice of Intent
(NOI) to prepare a draft Environmental Impact Statement (EIS) to
support the Dam Safety Modification Study Report (DSMSR) for Center
Hill Dam.
ADDRESSES: U.S. Army Corps of Engineers, Nashville District, 110 9th
Avenue South, RM 405A, Nashville, Tennessee 37203-3817.
FOR FURTHER INFORMATION CONTACT: Joy Broach, Aquatic Biologist, (615)
736-7956; email: [email protected].
SUPPLEMENTARY INFORMATION: USACE published an NOI in the Federal
Register on Friday, April 20, 2018 (77 FR 17541) to prepare a draft EIS
pursuant to the National Environmental policy Act (NEPA) for the DSMSR.
A scoping letter was circulated to federal, state, and local agencies,
political officials, and the public on April 20, 2018. A public scoping
meeting was held on May 3, 2018 to solicit public comments regarding
environmental concerns for seven potential alternatives to lower risk
at Center Hill Dam. Since the public meeting on May 3, 2018, and after
additional engineering studies, the proposed alternatives have been
evaluated. Several measures considered structural changes to existing
spillway gate machinery to maximize spillway flow for extreme flood
events. One measure considered adding spillway gates near the saddle
dam and one measure considered changing the emergency operating
schedule for spillway gate operations. The dam safety modification dam
safety study recommended plan is maintenance rehabilitation of the
electrical system, gate machinery and brakes to increase reliability,
along with adding capability to remotely operate the gates from the top
of the dam during an extreme flood event. The recommended plan does not
include relocation or long-term road closure of Highway 96. The
measures addressing spillway gate maintenance to increase gate
reliability, are being recommended as a result of the dam safety
modification study. These measures are considered routine operation and
maintenance of the existing dam structure; they are categorically
excluded from NEPA documentation and do not require an EIS. Therefore,
the NOI to prepare an EIS is withdrawn with this notice.
Dated: December 11, 2018.
