PUBLIC NOTICE
LAKE TAHOMA, INC., REPRESENTED BY DR. WILLIAM GRIFFIN, POST OFFICE BOX
1330, MARION, NORTH CAROLINA 28752 has applied for a Department of the Army
(DA) permit TO EXCAVATE BY DRAGLINE 52,000 CUBIC YARDS OF ACCUMULATED SEDIMENT
FROM WITHIN AN APPROXIMATELY 137,000 SQUARE FOOT BOTTOM AREA IN THE
NORTHEASTERN ARM OF LAKE TAHOMA (LITTLE BUCK CREEK). LAKE TAHOMA IS LOCATED
NORTHWEST OF MARION, OFF OF NC 80, IN MCDOWELL COUNTY, NORTH CAROLINA.
The following description of the work is taken from data provided by the
applicant and from observations made during a site visit by a representative
of the Corps of Engineers. Plans submitted with the application show the
proposed excavation of an estimated 52,000 cubic yards of sediment from an
approximately 137,000 square foot area near the mouth of Little Buck Creek in
the northwestern arm of Lake Tahoma. As would be expected, sediment is
deposited in this area of the lake as a result of creek flow entering the
standing water of the lake. The sediment accumulation prevents safe boating
and other recreational usage of this part of the lake. The first phase of the
project will involve the construction of access roadways, dredged material
disposal basins, and an equipment staging and dredging access area. The road
construction and staging area will result in the discharge of stone and rock
fill within two waters and wetlands jurisdictional areas. Site one occurs at
the equipment staging/dredging access area at the north end of the lake.
Approximately 400 square feet of wetland will be filled at this location.
Site two consists of an approximately 35 foot wide and twelve foot long creek
crossing. Two 36 inch diameter culverts are to be installed in the creek and
backfilled with washed stone and rock. The estimated width of the road
surface is 15 feet. The crossing will result in the loss of approximately
425 square feet of open water area. Three upland diked disposal areas are
planned to receive the estimated 52,000 cubic yards of dredged material. The
basins are located on the north and northeast side of the dredging area, and
will provide approximately 2.76 acres of combined storage capacity. The
basins and access roads will be left in place following project construction
in order to accommodate future maintenance dredging activities. Prior to
starting the excavation activity, the lake is to be lowered 12 to 14 feet
below the full pond elevation (100 feet). Dredging will commence once the
reservoir level has been lowered and the sediment has dried out enough to
adequately support equipment loading. Equipment to be utilized will consist
of a dragline, backhoe, and dumptrucks. Excavated material will be trucked tc
one of the nearby permanent storage sites.
After the dredging work is completed, the applicant proposes to install a
sediment retention baffle in the lake near the mouth of Little Buck Creek.
The baffle is to consist of steel sheet pile driven 30 feet into the lakebed
and extending 300 feet across the arm of the lake. The top of the baffle will
be at elevation 100.5 or 0.5 feet above full pond. A 220 foot wide notch (at
elevation 99) will be placed in the approximate center of the baffle to serve
as a spillway or outlet weir. The baffle is for the purpose of containing
sediment deposits within a reasonable distance from the permanent disposal
basins and access roads. The structure will be installed after the initial
sediment removal and may not occur during the initial phase scheduled to begin
t
-2-
during the calendar year 1998 and 1999. Plans showing the proposed work are
included with this public notice. The overall purpose of the project is to
provide immediate and long term relief from sedimentation effects in Lake
Tahoma. The applicant expects the project to improve boating opportunities,
fishing, aesthetics, and other recreational uses within the lake.
The State of North Carolina will review this public notice to decide the
need for the applicant to obtain any required State authorization. No
Department of the Army (DA) permit will be issued until the coordinated State
viewpoint on the proposal has been received and reviewed by this agency, nor
will a DA permit be issued until the North Carolina Division of Environmental
Management (NCDEM) has decided the applicability of a Water Quality
Certificate as required by PL 92-500.
Approval of this permit will authorize maintenance dredging for a period
not to exceed 10 years from the date of permit issuance. The permittee will
be required to present plans to the District Engineer a minimum of two (2)
weeks before commencement of maintenance work. All maintenance would be
performed according to Federal, State, and local permits and regulations
governing such activities at the time the maintenance is undertaken.
This application is being considered pursuant to Section 10 of the River
and Harbor Act of 1899 (33 U.S.C. 403) and Section 404 of the Clean Water Act
(33 U.S.C. 1344). Any person may request, in writing within the comment
period specified in this notice, that a public hearing be held to consider
this application. Requests for public hearing shall state, with
particularity, the reasons for holding a public hearing.
This application is being considered pursuant to Section 404 of the Clean
Water Act (33 U.S.C. 1344). Any person may request, in writing within the
comment period specified in the notice, that a public hearing be held to
consider this application. Requests for public hearing shall state, with
particularity, the reasons for holding a public hearing.
The District Engineer has consulted the latest published version of the
National Register of Historic Places for the presence or absence of registered
properties, or properties listed as being eligible for inclusion therein, and
this site is *not registered property or property listed as being eligible for
inclusion in the Register. Consultation of the National Register is the
extent of cultural resource investigations by the District Engineer, and he is
otherwise unaware of the presence of such resources. Presently, unknown
archeological, scientific, prehistorical, or historical data may be lost or
destroyed by work under the requested permit.
The District Engineer, based on available information, is not aware that
the proposed activity will affect species, or their critical habitat,
designated as endangered or threatened pursuant to the Endangered Species Act
of 1973.
The decision, whether to issue a permit, will be based on an evaluation
of the probable impacts, including cumulative impacts, of the proposed
activity and its intended use on the public interest. Evaluation of the
probable impacts that the proposed activity may have on the public interest
requires a careful weighing of all those factors that become relevant in each
particular case. The benefits that may be expected to accrue from the
proposal must be balanced against its foreseeable detriments. The decision
whether to authorize a proposal, and if so the conditions under which it will
-3-
be allowed to occur, are therefore decided by the outcome of the general
balancing process. That decision should reflect the national concern for both
protection and use of important resources. All factors that may be relevant
to the proposal must be considered including the cumulative effects of it.
Among those are conservation, economics, aesthetics, general environmental
concerns, wetlands, cultural values, fish and wildlife values, flood hazards
and flood plain values (according to Executive order 11988), land use,
navigation, shore erosion and accretion, recreation, water supply and
conservation, water quality, energy needs, safety, food and fiber production,
mineral needs, considerations of property ownership, and, in general, the
needs and welfare of the people. For activities involving the placement of
dredged or fill materials in waters of the United States, a permit will be
denied if the discharge that would be authorized would not comply with the
Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the
preceding sentence and any other applicable guidelines or criteria, a permit
will be granted unless the District Engineer decides that it would be contrary
to the public interest.
The Corps of Engineers is soliciting comments from the public; Federal,
State and local agencies and officials; Indian Tribes and other interested
parties to consider and evaluate the impacts of this proposed activity. Any
comments received will be considered by the Corps of Engineers to decide
whether to issue, modify, condition or deny a permit for this proposal. To
make this decision, comments are used to assess impacts on endangered species,
historic properties, water quality, general environmental effects and the
other public interest factors listed above. Comments are used in the
preparation of an Environmental Assessment (EA) and/or an Environmental Impact
Statement (EIS) pursuant to the National Environmental Policy Act (NEPA).
Comments are also used to decide the need for a public hearing and to decide
the public interest of the proposed activity.
Generally, the decision whether to issue this Department of the Army (DA)
permit will not be made until the North Carolina Division of Environmental
Management (NCDEM) issues, denies, or waives State certification required by
Section 401 of the Clean Water Act. The NCDEM considers whether the proposed
activity will comply with Sections 301, 302, 306, and 307 of the Clean Water
Act. The application and this public notice for the Department of the Army
(DA) permit serves as application to the NCDEM for certification.
Additional information regarding the Clean Water Act certification may be
reviewed at the offices of the Environmental Operations Section, North
Carolina Division of Environmental Management (NCDEM), Salisbury Street,
Archdale Building, Raleigh, North Carolina. Copies of such materials will be
furnished to any person requesting copies upon payment of reproduction costs.
All persons wanting to make comments regarding the application for Clean
Water Act certification should do so in writing delivered to the Division of
Water Quality, North Carolina Department of Environment, Health, and Natural
Resources (NCDEHNR), 4401 Reedy Creek Road, Raleigh, North Carolina 27607, on
or before December 15, 1997, Attention: Mr. John Dorney.
Written comments pertinent to the proposed work, as outlined above, will
be received in this office, Attention: Mr. Steve Chapin, until 4:15 p.m.,
December 19, 1997, or telephone [phone].
