Intent To Prepare a Draft Supplemental Environmental Impact 
Statement (DSEIS) for the Nourishment of 25,000 feet of Beach in 
Topsail Beach, Pender County, NC

AGENCY: Department of the Army, U.S. Army Corps of Engineers, DoD.

ACTION: Notice of intent.

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

SUMMARY: The U.S. Army Corps of Engineers (USACE), Wilmington District, 
Wilmington Regulatory Field Office has received a request for 
Department of the Army authorization, pursuant to Section 404 of the 
Clean Water Act and Section 10 of the Rivers and Harbors Act, from the 
Town of Topsail Beach to conduct a one-time emergency beach fill 
project to protect oceanfront development and infrastructure until such 
time that a federally authorized shore protection project can be 
implemented. At this time, the construction date for the Federal 
project is uncertain. A Draft General Reevaluation Report--
Environmental Impact Statement (GRR-EIS) has been prepared by the USACE 
and was released for public review and comment in June 2006 (USACE, 
2006). Given the current status of the GRR-EIS and the need for 
Congressional authorization, funding, preparation of plans and 
specifications, and right-of-way acquisition, the Federal project may 
not be implemented until Fiscal Year 2010, or possibly later.

ADDRESSES: Copies of comments and questions regarding scoping of the 
DSEIS may be addressed to: U.S. Army Corps of Engineers, Wilmington 
District, Regulatory Division. ATTN: File Number SAW-2006-40848-071, 
Post Office Box 1890, Wilmington, NC 28402-1890.

FOR FURTHER INFORMATION CONTACT: Questions about the proposed action 
and DSEIS can be directed to Mr. Dave Timpy, Wilmington Regulatory 
Field Office, telephone: (910) 251-4634.

SUPPLEMENTARY INFORMATION: The Topsail Emergency Beach Nourishment 
project was placed on Public Notice on December 15, 2006 and a Notice 
of Intent issued on December 15, 2006 (71 FR 75511). A Scoping Meeting 
was held on January 16, 2007. Subsequently, another borrow area has 
been found. Therefore, this Notice of Intent is issued to include 
another borrow area into the project.
    1. Project Description. The fill placement area will occur between 
Godwin Avenue on the south to a point 2,000 feet northeast of Topsail 
Beach/Surf City town limits, a total ocean shoreline length of 
approximately 25,000 feet. The fill would consist of three sections, a 
1,000-foot transition on the south beginning at a point opposite Godwin 
Avenue, a 22,000-foot main fill section that would extend to the 
Topsail Beach/Surf City town limits, and a 2,000-foot northern 
transition (Figure 1). The project design will remain consistent with 
the Federal design and will involve a berm system to be constructed to 
a height of 7 feet NGVD. An optimum berm width of 50 feet is proposed. 
The in-place volume of the beach fill has not been determined but could 
range between 900,000 to 1,250,000 cubic yards. Offshore sand sources 
are currently being investigated for sediment compatibility with the 
native beach material. The offshore borrow areas under consideration 
include all of the areas within the 3-mile North Carolina territorial 
limit previously identified by the USACE in the GRR-EIS (Borrow Areas A 
and B), areas lying outside of the USACE identified borrow areas, and 
an area designated as Borrow Area X located closer to shore (Figure 1). 
The navigation channel running through Banks Channel from New Topsail 
Inlet through Topsail Creek and from Topsail Creek parallel to the 
barrier island to the Atlantic Intracoastal Waterway (Figure 1) was 
considered as a potential source for the one-time emergency beach fill 
project but dismissed due to the small volume of material that would be 
available. The authorized dimensions of the navigation channel are 80 
feet wide at 7 feet below mean low water. During normal maintenance 
operations, between 50,000 and 200,000 cubic yards are removed and 
deposited on the south end of Topsail Beach. This relatively small 
volume of maintenance material would fall well below the emergency 
project requirements. Furthermore, maintenance dredging is currently 
being performed in Banks Channel with the dredged material being placed 
on the south end of Topsail Beach. The current maintenance operation 
would totally deplete the volume of material available for beach 
disposal for at least the next two years. Accordingly, the navigation 
channels running behind Topsail Beach will not be given detailed 
consideration for the emergency project.
    The proposed construction timeframe for the emergency beach fill 
activities will occur in late calendar year 2008 or early calendar year 
2009.

vicinity of Topsail Beach, North Carolina.
    Beach Fill Surveys & Design. Typical cross-sections of the beach 
along the Topsail Beach project area will be surveyed. Nearshore 
profiles will extend seaward to at least the -30-foot NAVD depth 
contour. The total volume of beach fill to be placed in front of the 
existing development and infrastructure will be based on an evaluation 
of erosion of the project area from 2002 through the expected 
construction date of the Federal project. Additional offshore and 
inshore data for Hutaff Island will also be obtained along the northern 
5,000 feet of the island. This data will be used in the evaluation of 
possible impacts associated with the removal of sediment from the 
selected offshore borrow area and for future impact evaluations 
following project implementation through the use of numerical modeling.
    Geotechnical Investigations. The offshore sand search 
investigations have included bathymetric surveys, sidescan sonar 
surveys, seismic surveys, cultural resource surveys, vibracore 
collection and analysis, and ground-truth diver surveys to verify 
existence or non-existence of hard bottoms. The results of the offshore 
investigations coupled with the compatibility of the sand resource area 
and native beach sand will be assessed to define the borrow area. All 
sediment compatibility assessments will be based on State of North 
Carolina sediment compatibility standards that went into effect in 
February 2007.
    Environmental Resource Coordination & Permitting. The USACE 
prepared a General Reevaluation Report--Environmental Impact Statement 
(GRR-EIS) for the larger Federal shore protection project. The interim 
(emergency) beach fill project will be subject to Section 10 of the 
Rivers and Harbors Act, Section 404 of the Clean Water Act and the 
State Environmental Policy Act (SEPA).
    Preliminary coordination with the USACE--Wilmington District 
resulted in a determination that a Department of the Army Application 
for an Individual Permit will be needed for project compliance with 
Sections 10 and 404. Similarly, coordination with the North Carolina 
Division of Coastal Management (NCDCM) determined that the project 
would require a State EIS developed in accordance with SEPA; as well as 
a Major Permit under the Coastal Area Management Act.
    2. Proposed Action. The scope of activities for the proposed 
emergency beach fill project included: (a) Vibracores in the identified 
borrow area, (b) side scan sonar surveys of the ocean bottom, (c) in-
water investigations of potential near shore hard bottom resources 
identified by the side scan sonar survey, and (d) beach profile 
surveys. Offshore investigations included bathymetric surveys, sidescan 
sonar surveys, seismic and cultural resource surveys, as well as 
vibracore collection and analysis. The results of the offshore 
investigations coupled with the compatibility of the sand resource area 
and native beach sand will be assessed to define the borrow area.

    3. Issues. There are several potential environmental issues that 
will be addressed in the DSEIS. Additional issues may be identified 
during the scoping process. Issues initially identified as potentially 
significant include:
    a. Potential impact to marine biological resources (benthic 
organisms, passageway for fish and other marine life) and Essential 
Fish Habitat, particularly Hard Bottoms.
    b. Potential impact to threatened and endangered marine mammals, 
birds, fish, and plants.
    c. Potential impacts to water quality.
    d. Potential increase in erosion rates to adjacent beaches.
    e. Potential impacts to navigation, commercial and recreational.
    f. Potential impacts to private and public property.
    g. Potential impacts on public health and safety.
    h. Potential impacts to recreational and commercial fishing.
    i. The compatibility of the material for nourishment.
    j. Potential economic impacts.
    4. Alternatives. Several alternatives are being considered for the 
proposed project. These alternatives will be further formulated and 
developed during the scoping process and an appropriate range of 
alternatives, including the No Action alternative, will be considered 
in the Supplemental Draft EIS.
    5. Scoping Process. Project Delivery Team meetings will be held to 
receive comments and assess concerns regarding the appropriate scope 
and preparation of the DSEIS. Participation in the meeting by federal, 
state, and local agencies and other interested organizations and 
persons is encouraged.
    The COE will also be consulting with the U.S. Fish and Wildlife 
Service under the Endangered Species Act and the Fish and Wildlife 
Coordination Act, and with the National Marine Fisheries Service under 
the Magnuson-Stevens Act and Endangered Species Act. Additionally, the 
Supplemental Draft EIS will assess the potential water quality impacts 
pursuant to Section 401 of the Clean Water Act, and will be coordinated 
with NCDCM to determine the projects consistency with the Coastal Zone 
Management Act. The USACE will closely work with NCDCM through the 
SDEIS to ensure the process complies with all State Environmental 
Policy Act (SEPA) requirements. It is the USACE and NCDCM's intentions 
to consolidate both NEPA and SEPA processes to eliminate duplications.
    6. Availability of the Draft Supplemental EIS. The DSEIS is 
expected to be published and circulated in early 2008, and a public 
hearing will be held after the publication of the DSEIS.
