PROJECT NAME: Discharge of Dredged Material on Pea Island National
Wildlife Refuge (PINWR) and Advanced Maintenance of the
Oregon Inlet Channel, Manteo (Shallowbag) Bay Project,
Dare County, North Carolina
DISCHARQE_OF: Dredged material
PROPOSED ACTIVITY TO BEGIN: Summer or Fall 1990
LOCATION OF DISCHARGE: Municipality: None
County: Dare
Drainage Basin: Coastal Area
Receiving Waters: Atlantic Ocean
Point of Discharge: Ocean Shoreline, PINWR
NATURE OF RECEIVING WATERS:
Type: Coastal
Nature: Salt
Direction of Flow: Variable
DESCRIPTION OF TREATMENT FACILITIES, IF ANY, PRIOR TO DISCHARGE INTO RECEIVING
WATERS: N/A
TYPE OF DISCHARGE INCLUDING CHEMICAL COMPOSITION, QUANTITY. FREQUENCY,
TEMPERATURE AND BINDS,, AND QUANTITIES OF POLLUTANTS OR CONTAMINANTS:
The proposed action consists of discharging sand from advance maintenance of
the Oregon Inlet navigation channel on the beach at PINWR using an ocean-
certified pipeline dredge. For the FY 90 maintenance effort, approximately
1.5 million cubic yards of material will be dredged and discharged. Advanced
maintenance dredging will be performed along the approximate channel
centerline as shown on the attached figure 1. Dredging will be performed up
to 2,000 feet east of the Bonner Bridge and approximately 2,000 feet west of
the bridge. Project depth will not exceed -17 feet m.l.w. Advanced
maintenance dredging width is contingent upon the characteristics of the flow
and shoaling patterns at the time of dredging. Due to dynamic conditions in
Oregon Inlet, this width may extend up to 1,000 feet on either side (south
and/or north) of the channel centerline during any given maintenance
operation. Current conditions in proximity of the navigation span suggest
that a width of 400 feet or greater may be needed south and/or north of the
centerline for the FY 90 maintenance. The need for and extent of increased
channel widths for advance maintenance will be determined at the time of each
future maintenance event. The extent of advanced maintenance dredging during
any particular year will be limited by the economic and budget restraints of
the project. Dredged material will be placed on the beach at PINWR from a
point approximately 1,500 feet south of Oregon Inlet and distributed southward
for a distance of approximately 15,000 feet. The actual discharge of material
will occur on the beach between the water and the seaward toe of the primary
dune. The work is currently scheduled to start in September 1990 and will
take approximately 120 days to complete. Some variation from this timeframe
may occur. The proposed action will also be performed in subsequent fiscal
years if warranted.
Dredged material will be conveyed to the beach via either an 18-inch pipeline
or a 27-inch pipeline. Material will be distributed throughout the deposition
area by adding lengths of pipe and progressing southward along the beach. All
material deposited will be shaped using earth-moving equipment to remove
mounded areas and create a beach with a natural appearance.
The dredging contractor will select one of two available pipeline routes, both
of which are shown on figure 1. The first option is to route the pipeline
seaward of the inlet, over nearshore ocean waters, to the point of deposition
on the beach. This option has the advantages of minimal impacts on
environmental resources and land transportation but exposes the pipeline to
the harsh wave climate present in the area. The second option is to route the
pipeline soundward through the inlet to the vicinity of the disposal island
behind Bonner Bridge and, from there, follow deep water to the edge of the
marsh. From landfall, the pipeline would be laid over the marsh using wide-
tracked vehicles to minimize rutting or compaction of marsh soils. This
technique has been used throughout North Carolina and it has been proven that
damage to salt marshes is avoided. No dredging of this pipeline route would
be necessary, as shallow water areas could be crossed by pulling and sliding
the pipeline. If the estuarine pipeline route is selected, the crossing of
N.C. 12 would be at a location to be determined in consultation with PINWR and
the North Carolina Department of Transportation. The road crossing will be
buried to allow passage of vehicle traffic.
During placement of material (and crossing of dunes, if necessary), disruption
of dune fields will be minimized. Any damage to dunes will be repaired
through shaping and planting upon completion of the project.
The material that will be discharged on the ocean beach at PINWR is predomi-
nantly coarse grain sand and is not contaminated or polluted.

DARE COUNTY, NORTH CAROLINA SEP 4 1990
TO WHOM IT MAY CONCERN:

THE WILMINGTON DISTRICT, CORPS OF ENGINEERS, Wilmington, North Carolina,
is preparing to perform maintenance dredging of the Oregon Inlet Channel and
to place the dredged material on the ocean beach fronting the Pea Island
National Wildlife Refuge (PINWR), Dare County, North Carolina.
PROJECT DESCRIPTION
The proposed action consists of discharging sand from dredging of the
Oregon Inlet Navigation Channel on the beach at PINWR using a pipeline dredge.
For the FY 90 maintenance effort, approximately 1.5 million cubic yards of
material will be dredged and discharged. Maintenance dredging will be
performed along the approximate channel centerline as shown on Figure 1.
Dredging will be performed up to 2,000 feet east of the Bonner Bridge and
approximately 2,000 feet west of the bridge. Project depth will not exceed
-17 feet mean low water (m.l.w.). Advanced maintenance dredging may be
performed and the width is contingent upon the characteristics of the flow and
shoaling patterns at the time of dredging. Due to dynamic conditions in
Oregon Inlet, this width may extend up to 1,000 feet on either side (south
and/or north) of the channel centerline during any given maintenance
operation. Current conditions in proximity of the navigation span suggest
that a width of 400 feet or greater may be needed south and/or north of the
centerline for the FY 90 maintenance. The need for and extent of increased
channel widths for advanced maintenance will be determined at the time of each
future maintenance event. The extent of advanced maintenance dredging during
any particular year will be limited by the economic and budget restraints of
the project. The beach disposal area at PINWR begins approximately 1,500 feet
south of Oregon Inlet and extends southward for a distance of approximately
15,000 feet. The actual discharge of material will occur on the beach between
the water and the seaward toe of the primary dune. The work is currently
scheduled to start in September 1990, and will take approximately 120 days to
complete. Some variation from this time frame may occur. The proposed action
will also be performed in subsequent fiscal years if warranted.

The proposed action is discussed in the Environmental Assessment and
Finding of No Significant Impact (EA/FONSI), Discharge of Dredged Material on
Pea Island National Wildlife Refuge and Advanced Maintenance of the Oregon
Inlet Channel, Manteo (Shallowbag) Bay Project, Dare County, North Carolina
dated July 1990. A copy of the EA/FONSI can be obtained by writing to Mr.
Daniel Small, Environmental Resources Branch, Wilmington District, Corps of
Engineers, Post Office Box 1890, Wilmington, North Carolina 28402-1890.
A Section 401 (PL 95-217) Water Quality Certificate has been requested
from the North Carolina Division of Environmental Management for the discharge
of dredged material on the ocean beach of PINWR. A Section 404(b)(1) (PL 95-
217) Evaluation and Finding of Compliance will be prepared for the beach
disposal prior to the discharge.
r
A Special Use Permit will be obtained from the PINWR to discharge dredged
material on the ocean beach at Pea Island.
The proposed action has been evaluated for adherence to the requirements
of Executive Order 11988, Floodplain Management. The project involves the
discharge of dredged material on an ocean beach. No practicable alternative
to the project being located in the flood plain exists. The proposed action
will not induce development in the flood plain. Every effort will be taken to
minimize potential harm to or within the flood plain. The action is in
compliance with state/local flood plain protection standards.

minimize potential harm to or within the flood plain. The action is in
compliance with state/local flood plain protection standards.
The proposed action has been evaluated under Executive Order 11990,
Protection of Wetlands. The work will not require dredging or filling of any
wetlands. Should the estuarine pipeline route option from the dredging site
to the ocean beach be selected, the dredge pipeline will cross coastal
wetlands. The proposed action includes all practicable measures to minimize
harm to wetlands. No significant adverse effects to wetlands will occur.
A Biological Assessment pursuant to Section 7 of the Endangered Species
Act of 1973, as amended, was prepared for the proposed action. The evaluation
of potential project impacts contained in the Biological Assessment determined
that the project would not affect any Federally-listed species.
It has also been determined that due to its location and limited scope,
discharge of dredged material on the beach at Pea Island will not adversely
affect the foraging or nesting patterns of any of the State-listed species of
colonially nesting waterbirds nor will it affect sea beach amaranth
(Amaranthus pumilus).
No adverse impact to archaeological or historic resources is anticipated
by the proposed discharge of dredged material on the beach at Pea Island.
This is due to continual erosion and westward migration of the beach.
'The proposed action has been coordinated with the North Carolina Division
of Coastal Management. A determination that the proposed project is
consistent with the North Carolina Coastal Management Program was included in
the EA/FONSI. A request for concurrence/nonconcurrence with the determination
has been sent to the North Carolina Division of Coastal Management (U.S. Army
Corps of Engineers letter to State Clearinghouse, July 23, 1990).
-4-
There is no other known or anticipated related dredging and discharge to
be conducted by others.
Attached is a list of Federal, state, and local agencies with whom this
activity is being coordinated.
The decision whether or not to perform this work will be based on an
evaluation of the probable impact, including cumulative impacts of the
proposed activity on the public interest. That decision will reflect the
national concern for both protection and utilization of important resources.
The benefits which reasonably may be expected to accrue from the proposal must
be balanced against its reasonably foreseeable detriments. All factors which
may be relevant to the proposal will be considered, including the cumulative
effects thereof; among those are conservation, economics, aesthetics, general
values, flood hazards, flood plain values, land use, navigation, shoreline
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.
Any person who has an interest which may be affected by the disposal of
this dredged material may request a public hearing. The request must be
submitted in writing to the District Engineer within 15 days of the date of
this notice and must clearly set forth the interest which may be affected and
the manner in which the interest may be affected by this activity. In order
for such a request to be given appropriate consideration, it should be mailed

DISCHARGE OF DREDGED MATERIAL ON PEA ISLAND NATIONAL 12 3 4 S6
WILDLIFE REFUGE AND ADVANCED MAINTENANCE
DREDGING OF THE OREGON INLET CHANNEL
MANTEO (SHALLOWBAG) BAY PROJECT P?6 0
DARE COUNTY, NORTH CAROLINA

TO WHOM IT MAY CONCERN:
THE WILMINGTON DISTRICT, CORPS OF ENGINEERS, Wilmington, North Carolina,
is preparing to perform maintenance dredging of the Oregon Inlet Channel and
to place the dredged material on the ocean beach fronting the Pea Island
National Wildlife Refuge (PINWR), Dare County, North Carolina.
PROJECT DESCRIPTION
The proposed action consists of discharging sand from dredging of the
Oregon Inlet Navigation Channel on the beach at PINWR using a pipeline dredge.
For the FY 90 maintenance effort, approximately 1.5 million cubic yards of
material will be dredged and discharged. Maintenance dredging will be
performed along the approximate channel centerline as shown on Figure 1.
Dredging will be performed up to 2,000 feet east of the Bonner Bridge and
approximately 2,000 feet west of the bridge. Project depth will not exceed
-17 feet mean low water (m.l.w.). Advanced maintenance dredging may be
performed and the width is contingent upon the characteristics of the flow and
shoaling patterns at the time of dredging. Due to dynamic conditions in
Oregon Inlet, this width may extend up to 1,000 feet on either side (south
and/or north) of the channel centerline during any given maintenance
operation. Current conditions in proximity of the navigation span suggest
that a width of 400 feet or greater may be needed south and/or north of the
centerline for the FY 90 maintenance. The need for and extent of increased
channel widths for advanced maintenance will be determined at the time of each
future maintenance event. The extent of advanced maintenance dredging during
any particular year will be limited by the economic and budget restraints of
the project. The beach disposal area at PINWR begins approximately 1,500 feet
south of Oregon Inlet and extends southward for a distance of approximately
15,000 feet. The actual discharge of material will occur on the beach between
the water and the seaward toe of the primary dune. The work is currently
scheduled to start in September 1990, and will take approximately 120 days to
complete. Some variation from this time frame may occur. The proposed action
will also be performed in subsequent fiscal years if warranted.

. Dredged material will be conveyed to the beach via a pipeline. Material
will be distributed throughout the deposition area by adding lengths of pipe
and progressing southward along the beach. All material deposited will be
shaped using earth-moving equipment to remove mounded areas and create a beach
with a natural appearance.

The dredging contractor will select one of two available pipeline routes,
both of which are shown on Figure 1. The first option is to route the
pipeline seaward of the inlet, over nearshore ocean waters, to the point of
deposition on the beach. This option has the advantages of minimal impacts on
environmental resources and land transportation, but exposes the pipeline to
the harsh wave climate present in the area. The second option is to route the
pipeline soutdward through the inlet to the vicinity of the disposal island
behind Bonner Bridge and, from there, follow deep water to the edge of the
marsh. From landfall, the pipeline would be laid over the marsh using wide-
tracked vehicles to minimize rutting or compaction of marsh soils. This
technique has been used throughout North Carolina, and it has been proven that
damage to salt marshes is avoided. No dredging of this pipeline route would
be necessary, as shallow water areas could be crossed by pulling and sliding
the pipeline. If the estuarine pipeline route is selected, the crossing of
N.C. 12 would be at a location to be determined in consultation with PINWR and
the North Carolina Department of Transportation. The road crossing will be
buried to allow passage of vehicular traffic.
During placement of material (and crossing of dunes, if necessary),
disruption of dune fields will be minimized. Any damage to dunes will be
repaired through shaping and planting upon completion of the project.
The proposed action is discussed in the Environmental Assessment and
Finding of No Significant Impact (EA/FONSI), Discharge of Dredged Material on
Pea Island National Wildlife Refuge and Advanced Maintenance of the Oregon
Inlet Channel, Manteo (Shallowbag) Bay Project, Dare County, North Carolina
dated July 1990. A copy of the EA/FONSI can be obtained by writing to Mr.
Daniel Small, Environmental Resources Branch, Wilmington District, Corps of
Engineers, Post Office Box 1890, Wilmington, North Carolina 28402-1890.
A Section 401 (PL 95-217) Water Quality Certificate has been requested
from the North Carolina Division of Environmental Management for the discharge
of dredged material on the ocean beach of PINWR. A Section 404(b)(1) (PL 95-
217) Evaluation and Finding of Compliance will be prepared for the beach
disposal prior to the discharge.

A Special Use Permit will be obtained from the PINWR to discharge dredged
material on the ocean beach at Pea Island.
The proposed action has been evaluated for adherence to the requirements
of Executive Order 11988, Floodplain Management. The project involves the
discharge of dredged material on an ocean beach. No practicable alternative
to the project being located in the flood plain exists. The proposed action
will not induce development in the flood plain. Every effort will be taken to
minimize potential harm to or within the flood plain. The action is in
compliance with state/local flood plain protection standards.

The proposed action has been evaluated under Executive Order 11990,
Protection of Wetlands. The work will not require dredging or filling of any
wetlands. Should the estuarine pipeline route option from the dredging site
to the ocean beach be selected, the dredge pipeline will cross coastal
wetlands. The proposed action includes all practicable measures to minimize
harm to wetlands. No significant adverse effects to wetlands will occur.
A Biological Assessment pursuant to Section 7 of the Endangered Species
Act of 1973, as amended, was prepared for the proposed action. The evaluation
of potential project impacts contained in the Biological Assessment determined
that the project would not affect any Federally-listed species.
It has also been determined that due to its location and limited scope,
discharge of dredged material on the beach at Pea Island will not adversely
affect the foraging or nesting patterns of any of the State-listed species of
colonially nesting waterbirds nor will it affect sea beach amaranth
(Amaranthus pumilus).
No adverse impact to archaeological or historic resources is anticipated
by the proposed discharge of dredged material on the beach at Pea Island.
This is due to continual erosion and westward migration of the beach.
The proposed action has been coordinated with the North Carolina Division
of Coastal Management. A determination that the proposed project is
consistent with the North Carolina Coastal Management Program was included in
the EA/FONSI. A request for concurrence/nonconcurrence with the determination
has been sent to the North Carolina Division of Coastal Management (U.S. Army
Corps of Engineers letter to State Clearinghouse, July 23, 1990).

There is no other known or anticipated related dredging and discharge to
be conducted by others.
Attached is a list of Federal, state, and local agencies with whom this
activity is being coordinated.
The decision whether or not to perform this work will be based on an
evaluation of the probable impact, including cumulative impacts of the
proposed activity on the public interest. That decision will reflect the
national concern for both protection and utilization of important resources.
The benefits which reasonably may be expected to accrue from the proposal must
be balanced against its reasonably foreseeable detriments. Ali factors which
may be relevant to the proposal will be considered, including the cumulative
effects thereof; among those are conservation, economics, aesthetics, general
values, flood hazards, flood plain values, land use, navigation, shoreline
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.
Any person who has an interest which may be affected by the disposal of
this dredged material may request a public hearing. The request must be
submitted in writing to the District Engineer within 15 days of the date of
this notice and must clearly set forth the interest which may be affected and
the manner in which the interest may be affected by this activity. In order
for such a request to be given appropriate consideration, it should be mailed
or delivered to the U.S. Army Engineer District, Wilmington, Post Office Box
1890, Wilmington, North Carolina 28402-1890, in time to be received on or
before September 17, 1990. All correspondence should refer to the title,
number, and date of this notice. For further information, contact Mr. Jimmy
