Notice of Availability of the Draft Environmental Impact
Statement for the Dam Safety Assurance Evaluation Report, Dover Dam,
City of Dover, Tuscarawas County, OH

AGENCY: Department of the Army, U.S. Army Corps of Engineers, DOD.
ACTION: Notice of availability.

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

SUMMARY: Pursuant to the National Environmental Policy Act (NEPA), the
U.S. Army Corps of Engineers (Corps), Huntington District has prepared
an Environmental Impact Statement (EIS) to disclose potential impacts
to the natural, physical, and human environment resulting from
modifications to Dover Dam. This high hazard dam does not conform to
current design standards related to stability and sliding during a
probable maximum flood. Modifications are proposed so the Dam will meet
these standards.

DATES: Written comments on the Draft Environmental Impact Statement
will be accepted for 45 days following publication of the U.S.
Environmental Protection Agency's Notice of Availability for this Draft
Environmental Impact Statement (DEIS) in the Federal Register
anticipated to occur on or before January 12, 2007.

ADDRESSES: Send all written comments and suggestions concerning this
proposed project to Rodney G. Cremeans, Project Manager PM-PP-P, U.S.
Army Corps of Engineers, Huntington District, 502 Eighth Street,
lrh01.usace.army.mil.

FOR FURTHER INFORMATION CONTACT: Mr. Rodney Cremeans, Telephone: (304)
399-5715.

SUPPLEMENTARY INFORMATION: Section 1203 of the Water Resources
Development Act of 1986 (Pub. L. 99-662) provides for modification of
completed Corps dams and related facilities for safety purposes due to
new hydrologic or seismic data or changes in state-of-the-art design or
construction criteria. The National Weather Service generalized
estimates of Probably Maximum Precipitation (PMP) were used to develop
flood scenarios and guide design criteria for structures such as Dover
Dam. These rainfall estimates are considered extreme, with a very low
probability of occurrence. However, the worst-case storms associated
with the PMP events retain some probability of occurrence. The Corps
has determined the dam cannot safely accommodate flooding from
theoretical Probably Maximum Flood (PMF) events. The dam is also
believed to be unstable against sliding under conditions below the PMF
due to known faulting and uncertain foundation bedrock quality. The
objectives of the project are to develop the most cost effective,
environmentally sound plan to upgrade Dover Dam to meet current
hydrologic design standards and to address stability issues associated
with inadequate bedrock foundation. The objectives also include
protecting project facilities including the adjacent park area and Ohio
Route 800.
    Three alternatives: (1) Raise Dam, (2) Dam Overtop and (3) No
Federal Action are evaluated in detail in the EIS. The Raise Dam
alternative would allow the dam to safely pass 100% of the PMF through
raising the existing non-overflow sections with concrete parapet walls
constructed on the existing dam. To address inadequate bedrock
foundation and potential for sliding under PMF conditions, the Raise
Dam alternative also includes installation of anchors in the spillway
and stilling basin. The Dam Overtop alternative would modify the
existing non-overflow section of the dam to withstand overtopping, and
also includes installation of anchors in the spillway and stilling
basin to address inadequate bedrock foundation. Under the No Federal
Action alternative no modifications would be done. The Raise Dam
alternative was chosen as the recommended plan because it more reliably
meets project objectives, minimizes costs, and has the least adverse
environmental effects.
    The Corps invites full public participation to promote open
communication and better decision-making. All persons and organizations
that have an interest in the Dover Dam Project are urged to participate
in this NEPA evaluation process. Assistance will be provided upon
request to anyone having difficulty with learning how to participate.
    A public meeting will be held on January 18th at 7 p.m. at the
McDonald Marlite Conference Center in New Philadelphia, OH. The public
hearing will be announced in advance through notices, media news
releases, and/or mailings.
