Manteo_204_-_Signed_FONSI_-_19November2014

FfNDTJNG OF NO SIGNIFICANT ENWACT
Detailed Project Report and Environmental Assessment
Maenteo, Old douse Channel, NC,
Section 204 Project
The EA documents the environmental considerations, alternatives considered, and the
FONSI documents the decision that no significant impacts to the human environment
would occur if the proposal is implemented. The EA and FONSI have been prepared
pursuant to NEPA in accordance with the Council on Environmental Quality (CEQ)
regulations as contained in 40 CFR Parts 1500 to 1508, which directs federal agencies on
how to implement the provisions of NEPA and the US Army Corps of Engineers
Department of the Army procedures for implementing NEPA (33 CFR Part 230).
Description of the Proposed Action sand No Action Alternative.
The Detailed Project Report and Environmental Assessment (DPR/EA),, dated February
2014, describes the proposed action as the Recommended Plan that best meets the
planning objectives of oyster habitat restoration and beneficial uses of dredged material
within the study area. The proposed action (Recommended Plan) (oyster reef
construction) involves use of dredged material from maintenance dredging of Old House
Channel to restore habitat by building submerged sand islands to be topped with cultch
for oyster reef restoration. Containment of sand for the submerged islands would be
accomplished using stone. A complex of three stone containment structures, each
enclosing a 5.07 -acre reef would be constructed. This plan reasonably maximizes
ecosystem restoration benefits and is acceptable to the USACE and local sponsor. The
alternative action would be the No Action Alternative: wherein no oyster restoration
efforts in the project area would be implemented under this authority.
Public can Agene v_Coorcl_ n atlona
On April 23, 2013, the DPRIEA, dated March 2013 was mailed to federal and state
agencies, local communities, and the interested public for a 30 -day review and comment
period. Comments received during the review period were reviewed and considered in
making the decision to sign the FONSI. Reviewer comments and Corps responses are
attached to this FONSI at attachment 1.

Section 7.0 of the DPR/EA provides information on the affected environment present in
the Manteo, Old House Channel area. The probable consequences (impacts and effects)
of the No Action Alternative and the proposed action on the environmental resources in
the study area were evaluated. In the long -term, implementation of the Proposed Action
will result in positive effects for the Pamlico Sound project area natural resources. No
adverse long -term effects would be expected. For the No Action Alternative no project
impacts would occur; however, the overall long -term restoration and dredged material
placement benefits of the proposed action would be forgone.

b, Facts and Conclusions Leading to the Fincling ofiVo SignaficcntImpact
(FOATSI)
Based on the results of the impact analyses, it has been determined that no significant
impacts would occur as a result of implementing the Proposed Action. The Proposed
Action would not have any unavoidable adverse effects, nor would it result in the
irreversible or irretrievable commitment of resources. Proceeding with the Proposed
Action would not significantly or adversely impact the affected environment.
Additionally, no significant cumulative effects would be expected.
c. FYaiclitrg qf A7o S% npficcaaat liFiip act.
I have reviewed the Detailed Project Report and Environmental Assessment for Manteo,
Old House Channel, NC, Section 204 Project dated February 2014, the information
provided by interested parties, and the information contained in this Finding of No
Significant Impact, and I find that the proposed action will not significantly affect the
quality of the human environment. Therefore, preparation of an Environmental Impact
Statement pursuant to Section 102(2)(c) of the National Environmental Policy Act of
1969, as amended, is not required.

Response 2: Containment structures were designed to withstand environmental conditions so that
materials would be contained onsite. Site surveys indicated that no SAV were present within the
immediate proposed construction area. In addition, known SAV beds in the area are located at
elevations above the reef construction area. This protects the SAV from burial from sloughing as
sediment would be unlikely to move upslope.
