Condition(s) of Certification:
1. That the activity be conducted in such a manner as
to prevent significant increase in turbidity
outside the area of construction or construction
related discharge (increases such that the
turbidity in the Stream is 25 NTU's or less are not
considered significant).
2. That the terminal end of the pipeline shall be
positioned landward of=--the mean high water line to
allow maximum settlement of suspended solids.
3. Nuisance materials such as glass, metals and
plastics should be removed from beaches as soon as
possible after pumping.
Violations of any condition herein set forth shall result in
revocation of this Certification.
This Certification shall become null and void unless the

Enclosed is an application for a Water Quality Certification,
pursuant to Section 401 of the Clean Water Act of 1977, as amended
(P.L. 95-217), for the discharge of dredged material on the ocean
beaches at Topsail-Surf City Beach, West Onslow Beach, and Onslow
Beach, Pender and Onslow Counties, North Carolina. Also enclosed
is a copy of the Environmental Assessment and Finding of No
Significant Impact (EA/FONSI) addressing the proposed dredging and
dredged material disposal.
The proposed work will include disposal of dredged material
obtained from the Atlantic Intracoastal Waterway in the vicinity
of the New Topsail Inlet, New River Inlet, and Bear to Browns
Inlet Crossings. These Atlantic Intracoastal Waterway channels
require frequent dredging. Because previously used diked upland
disposal areas are nearly full and additional diked disposal areas
are not available, beach disposal of this material is the proposed
long-term disposal method.
If you have any questions concerning the enclosed application,
please contact Mr. Philip Payonk, Environmental Resources Branch,
at [phone].

RESPONSIBLE INDIVIDUAL:
PROJECT NAME: Thomas C. Suermann
Lieutenant Colonel,
Corps of Engineers
District Engineer
Maintenance of the Atlantic Intracoastal Waterway
(AIWW), Beaufort to Cape Fear Reach, New Topsail Inlet,
New River Inlet, and Bear to Browns Inlet Crossings,
Pender and Onslow Counties, North Carolina
NATURE OF THE ACTIVITY: Disposal of dredged material from the AIWW on
the ocean beaches at Topsail Beach - Surf
City, West Onslow Beach, and Onslow Beach
DISCHARGE OF: Dredged Material
PROPOSED ACTIVITY TO BEGIN:
Discharge will be scheduled to occur between November 16 and April 30
of any year, to the maximum extent practicable. However, experience
with similar projects in North Carolina indicates that work extending
beyond that period will eventually be necessary.
LOCATION OF DISCHARGE:
Municipalities: Topsail Beach, Surf City, West Onlsow Beach
(unincorporated), and Onslow Beach (Marine Corps
Base, Camp Lejeune)
Counties: Pender and Onslow
Drainage Basin: N/A
Receiving Waters: Atlantic Ocean
Point of Discharge: Same as receiving waters
NATURE OF RECEIVING WATERS:
Type: Ocean
Nature: Salt
Direction of Flow: Variable
DESCRIPTION OF TREATMENT FACILITIES, IF ANY, PRIOR TO DISCHARGE INTO
RECEIVING WATERS: None
"TYPE OF DISCHARGE, INCLUDING CHEMICAL COMPOSITION, QUANTITY
FREQUENCY, TEMPERATURE, AND KINDS AND QUANTITY OF POLLUTANTS OR
CONTAMINANTS:
Fine-to-medium sands with some silts and clays will be dredged from
the following AIWW inlet crossings and vicinities:
AIWW Nomenclature
Inlet Crossing Section Tangent See Figure*
New Topsail III 7 & 8 2
New River III 1 3
II I & J 3
Bear to Browns II F 4
* Figure 1 is a overall project area map
The results of sampling and grain-size analyses of sediments from the
channels to be dredged are given in table 1.
These AIWW channels require frequent dredging, approximately every
other year. Because previously used diked upland disposal areas are
nearly full and additional diked disposal areas are not available,
beach disposal of this material is the proposed long-term disposal
method.
Approximately 250,000 cubic yards are proposed to be dredged from the
above listed AIWW channels and disposed of on the beach in FY 90. The
quantity of dredged material will vary for each dredging event and
could be more or less than the quantities given for FY 90.
No known pollutants or contaminants will be introduced, relocated, or
increased.
TYPE, DIAMETER, OR CROSS SECTION AND LENGTH OF CONVEYANCE OF
DISCHARGE:
Dredging will be accomplished by a hydraulic pipeline dredge. A
temporary pipeline will transport the dredged material from the AIWW
channel across to the ocean beach disposal area. After crossing the
beach dunes, the pipeline will extend parallel to the beach, as
needed, to distribute the dredged material. A booster pump may be
required because of the pipeline lengths. The location of the
pipeline will depend on the location of the shoals to be dredged,
which may vary with each dredging cycle, and on obtaining necessary
easements from local municipalities and property owners. The possible
beach disposal limits are shown on figures 2-4. Only a portion of the
Topsail Beach - Surf City area indicated would be required for any one
dredging and beach disposal cycle, depending on the location of the
shoal to be dredged.
PROJECTED FUTURE VARIATION IN THE NATURE OF THE DISCHARGE: None
'NAMES AND ADDRESSES OF ADJOINING RIPARIAN OWNERS: Unknown

thereof is true and correct to the best of my knoKledge.

MAINTENANCE OF ATLANTIC INTRACOASTAL WATERWAY (AIWW)
BEAUFORT TO CAPE FEAR RIVER REACH
NEW TOPSAIL INLET, NEW RIVER INLET, AND BEAR TO BROWNS INLET CROSSINGS
(Pender and Onslow Counties,'North Carolina)
TO WHOM IT MAY CONCERN:
The Wilmington District, Corps of Engineers, Wilmington, North.Carolina,
proposes to perform maintenance dredging in the Atlantic Intracoastal Waterway
(AIWW) in the vicinity of New Topsail Inlet, New River Inlet, and Bear to Browns
Inlet crossings.
PROJECT DESCRIPTION
This maintenance work is scheduled to begin after January 15, 1990, and to
be complete no later than April 30, 1990, requiring approximately 45 days to
perform. The work will require the removal of shoals lying above the plane of
14 feet below mean low water (m.l.w.) within the designated AIWW.channel limits,
Beaufort to Cape Fear Reach, Section III Tangents 7, 8, and 1, and Section II
Tangents I, J, and F as shown on figures 1-4. The dredging to be performed in
FY 90 is:
AIWW Nomenclature Estimated
Inlet Crossing Section Tangent FY 90 Dredging (cu yds)
New Topsail III 8 50,000
New River III & II 1, I, J 50,000
Bear to Browns II F 150,000
The grain-size distribution of sediments in the channels proposed for
dredging in FY 90 ranges from 99 to 84 percent sand.
The work will be accomplished by use of a hydraulic pipeline dredge selected
by competitive bidding. For FY 90, the dredged material will be disposed of on
Topsail Beach-Surf City, West Onslow Beach, and Onslow Beach within the areas
designated on figures 2-4. No related dredging and beach disposal, conducted by
others, is anticipated.
A drawing showing the work and disposal area is enclosed with this notice.
1
l
The proposed'beach disposal area is within the flood plain. The dredging`
and discharge of dredged material on the beach has been evaluated for adherence
to the requirements of Executive Order 11988, Flood Plain Management. The
proposed actions maintain navigability and help minimize the impacts of floods
on human safety, health, and welfare. In order to ensure navigability of the
AIWW, the proposed activities must be located in the flood plain.
The proposed action has been evaluated under Executive Order 11990,
Protection of Wetlands. The work will not require dredging or filling of any
wetlands. The discharge pipeline may cross wetlands to reach the beach disposal
site. Where the pipeline crosses wetlands, pipeline joints will be welded and
burlapped to provide protection from leakage. Any impacts to wetlands will be
minor and of short duration.
There is enclosed a list of Federal, State, and local agencies with whom
this activity is being coordinated.
The maintenance dredging of AIWW New Topsail Inlet, New River Inlet, and
Bear to Browns Inlet crossings is addressed in the Final Environmental Impact
Statement (FEIS), Maintenance of the Atlantic Intracoastal Waterway, North
Carolina (filed with the Council on Environmental Quality on November 21, 1975).
An Environmental Assessment and Finding of No Significant Impact (EA/FONSI),
Maintenance of Atlantic Intracoastal Waterway (AIWW), Beaufort to Cape Fear
River Reach, New Topsail Inlet, New River Inlet, and Bear to Browns Inlet
Crossings, Pender and Onslow Counties., was made available for public review and
comment on October 19, 1989.
No impacts to known archaeological/historical resources will occur.
No impacts to endangered species are expected if the proposed work occurs
between November 16 and April 30. However, if the proposed maintenance dredging
and beach disposal of dredged material occur between May 1 and November 15, it
could impact nesting loggerhead or green sea turtles, species protected by the
Endangered Species Act of 1973, as amended. If dredged material is discharged
on the beach during the turtle nesting season, daily monitoring of sea turtle
nesting efforts in the beach impact area and nest relocation, as needed, will be
required in order to minimize potential adverse impacts to these species. Also,
the hatching success of all nests in the project area will be monitored. This
program will be coordinated with the U.S. Fish and Wildlife Service and the
North Carolina Wildlife Resources Commission.
A Section 401 (P.L. 95-217) Water Quality Certificate has been requested
from the North Carolina Division of Environmental Management for the disposal
of dredged material from the AIWW on beaches as described herein. A Section
404(b)(1) (P.L. 95-217) Evaluation and Findings of Compliance will be prepared
for the beach disposal prior to the discharge.
The proposed action is consistent with the approved Coastal Management
Program of the State of North Carolina. This action has been coordinated with
the North Carolina Division of Coastal Management, and concurrence with the
consistency determination has been requested.
2
The decision whether 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 environmental concerns,
wetlands, historic properties, fish and wildlife 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 30 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
November 20, 1989. All correspondence should refer to the title, number, and
date of this notice. For further information, contact Mr. Philip Payonk at

The work will be accomplished by use of a hydraulic pipeline dredge selected
by competitive bidding. For FY 90, the dredged material will be disposed of on
Topsail Beach-Surf City, West Onslow Beach, and Onslow Beach within the areas
designated on figures 2-4. No related dredging and beach disposal, conducted by
others, is anticipated.
A drawing showing the work and disposal area is enclosed with this notice.

V- I

The proposed beach disposal area is within the flood plain. The dredging
and discharge of dredged material on the beach has been evaluated for adherence
.to the requirements of Executive Order 11988, Flood Plain Management. The
proposed actions maintain navigability and help minimize the impacts of floods
on human safety, health, and welfare. In order to ensure navigability of the
AIWW, the proposed activities must be located in the flood plain.
The proposed action has been evaluated under Executive Order 11990,
Protection of Wetlands. The work will not require dredging or filling of any
wetlands. The discharge pipeline may cross wetlands to reach the beach disposal
site. Where the pipeline crosses wetlands, pipeline joints will be welded and
burlapped to provide protection from leakage. Any impacts to wetlands will be
minor and of short duration.
There is enclosed a list of Federal, State, and local agencies with whom
this activity is being coordinated.
The maintenance dredging of AIWW New Topsail Inlet, New River Inlet, and
Bear to Browns Inlet crossings is addressed in the Final Environmental Impact
Statement (FEIS), Maintenance of the Atlantic Intracoastal Waterway, North
Carolina (filed with the Council on Environmental Quality on November 21, 1975).
An Environmental Assessment and Finding of No Significant Impact (EA/FONSI),
Maintenance of Atlantic Intracoastal Waterway (AIWW), Beaufort to Cape Fear
River Reach, New Topsail Inlet, New River Inlet, and Bear to Browns Inlet
Crossings, Pender and Onslow Counties, was made available for public review and
comment on October 19, 1989.
No impacts to known archaeological/historical resources will occur.
No impacts to endangered species are expected if the proposed work occurs
between November 16 and April 30. However, if the proposed maintenance dredging
and beach disposal of dredged material occur between May 1 and November*15, it
could impact nesting loggerhead or green sea turtles, species protected by the
Endangered Species Act of 1973, as amended. If dredged material is discharged
on the beach during the turtle nesting season, daily monitoring of sea turtle
nesting efforts in the beach impact area and nest relocation, as needed, will be
required in order to minimize potential adverse impacts to these species. Also,
the hatching success of all nests in the project area will be monitored. This
program will be coordinated with the U.S. Fish and Wildlife Service and the
North Carolina Wildlife Resources Commission.
A Section 401 (P.L. 95-217) Water Quality Certificate has been requested
from the North Carolina Division of Environmental Management for the disposal
of dredged material from the AIWW on beaches as described herein. A Section
404(b)(1) (P.L. 95-217) Evaluation and Findings of Compliance will be prepared
for the beach disposal prior to the discharge.
The proposed action is consistent with the approved Coastal Management
Program of the State of North Carolina. This action has been coordinated with
the North Carolina Division of Coastal Management, and concurrence with the
consistency determination has been requested.
2

The decision whether 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 environmental concerns,
wetlands, historic properties, fish and wildlife 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 30 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
November 20, 1989. All correspondence should refer to the title, number, and
date of this notice. For further information, contact Mr. Philip Payonk at

PENDER & ONSLOW COUNTIES, NORTH CAROLINA
DATE: October 19, 1989
1. PROJECT DESCRIPTION
a. Authorized Project. The River and
450/69/1) authorized a channel 12 feet
constructed from Beaufort, North Carolina to
channel, which comprises a portion of the
(AIWW), was completed in 1932. The North Car,
the project areas are shown in Figure 1.
Harbor Act of 1927 (H.D.
deep and 90 feet wide to be
the Cape Fear River. The
Atlantic Intracoastal Waterway
Mina portion of the AIWW and
b. Proposed Action. The proposed action is the maintenance
dredging of the AIWW in the vicinity of the New Topsail, New River, and
Bear to Browns Inlet crossings by hydraulic pipeline dredge with discharge
of dredged material on nearby beaches. The proposed work involves the
removal of shoals lying above the plane of 14 feet below mean low water
(mlw) within the designated channel limits. The AIWW section and tangent
nomenclature for the inlet crossing areas addressed by this environmental
assessment is given in Table 1.
The limits of the proposed Topsail Beach - Surf City (New Topsail Inlet
Crossing), West Onslow Beach (New River Inlet Crossing), and Onslow Beach
(Bear to Browns Inlet Crossing) disposal areas are shown on Figures 2-4.
Only a portion of the Topsail Beach - Surf City beach disposal area shown
will be used for any one maintenance dredging cycle. The location and
length of Topsail Beach - Surf City beach used for dredged material
deposition will depend on the location of shoal areas within the AIWW and
the quantity of materials within those shoals. It is expected that the
dredged material will be dispersed along approximately 5,000 feet of beach
front for any given maintenance dredging cycle.

environmental assessment.

AIWW maintenance dredging records for the above-specified inlet
crossing areas over the last 23 years are illustrated in Figure 5. Table 2
provides projections of maintenance dredging requirements based on the
1966-1989 maintenance dredging records. The quantity of dredged material
and specific shoal locations may vary for each future dredging event and
could be more or less than the quantities given in Table 2. With respect
to the Bear to Browns Inlet crossing area, the currently approved disposal
method, which is unconfined bank disposal, allows dredged material to
return to the channel, thus increasing the channel shoaling rate.
Accordingly, if the dredged material is completely removed from the channel
area via beach disposal, the shoaling rate for this channel should
decrease.
Table 2. Projected maintenance dredging requirements.

Section II Tangent I 25,000 every year
Bear to Browns
Section II Tangent F 100,000 every 4 years
* Based on unconfined bank disposal
c. Need for the Proposed Action. Historically, diked upland
disposal methods have been used during AIWW maintenance dredging in the New
Topsail and New River Inlets vicinities. These disposal areas are shown
on Figures 2 and 3 for New Topsail and New River Inlets, respectively. For
maintenance dredging in the Bear to Browns Inlet area, the disposal method
has been unconfined bank disposal. The use of diked upland disposal areas
in this portion of the AIWW was not possible because of the presence of
undetonated high explosive ordnance associated with the U.S. Marine Corps
Base, Camp Lejeune. The diked upland disposal areas associated with the
AIWW New Topsail and New River Inlet crossings are essentially full and
have only limited capacity for future maintenance dredging. The unconfined
disposal on adjacent banks between Bear and Browns Inlets could continue
indefinitely. However, beach disposal of material from those areas may
reduce dredging requirements by removing the shoal materials from the area.
d. Existing Environmental Clearances. The maintenance dredging of
the New Topsail, New River, and Bear to Browns Inlet Crossings was
addressed in the Final Environmental Impact Statement (FEIS), Maintenance
of the Atlantic Intracoastal Waterway, North Carolina (filed with the
Council on Environmental Quality on November 21, 1975). With respect to
dredged material disposal, the above-cited FEIS addressed the unconfined
bank disposal for the AIWW Bear to Browns Inlet crossing area. The FEIS,

Maintenance of Atlantic Intracoastal Waterway Side Channels, North Carolina
(filed with the Council on Environmental Quality on November 29, 1976)
addressed the specific diked upland disposal areas previously mentioned for
the AIWW New Topsail and New River Inlet crossings. The AIWW Side Channels
FEIS also addressed beach disposal (on Topsail Beach and Lea Island) for
dredged material from the New Topsail Inlet channel.
The current maintenance of the New Topsail, New River, and Bear to
Browns Inlet crossings of the AIWW is consistent with the North Carolina
Coastal Management Program as indicated in Table 3.

Effluent from the diked upland disposal sites previously used for the
AIWW New Topsail and New River Inlet crossings is covered under Section 401
(PL 95-217) Water Quality Certificate No. 1273 issued on November 10, 1978,
and Nationwide Permit 33 CFR 330.5(a)(16). The discharge of dredged
material along the bank during the maintenance of the AIWW between Bear and
Browns Inlets is covered under Section 401 (PL 95-217), Water Quality
Certificate No. 1329 issued on June 13, 1979. Water Quality Certificate
No. 1264 issued on October 9, 1978 provides for the discharge of dredged
materials on downdrift beaches at specific inlets, including New Topsail
and New River, resulting from maintenance excavation of AIWW inlet
crossings.
e. Acceptability of Dredged Materials For Beach Disposal. Bottom
sediments in the channels proposed for dredging were sampled during June
1989. Figures 2-4 indicate the sample locations. Sand content and median
grain size in sediment samples from channel areas to be dredged are
summarized in Table 4. The sampling and analyses are discussed further in
Appendix A. This data indicates that the dredged material from the
channels sampled is acceptable for beach disposal.
Table 4. Summary of Sediment Sampling and Grain Size Analyses.
See Appendix A for methods, station locations, and complete data. For
this analysis sand is defined as material retained by U.S. Standard
Sieve No. 200 or > 0.074 mm grain size. Median grain size is the
particle size at which half of the particles by weight are coarser
and half are finer. It is the diameter corresponding to the 50
percent mark on the cumulative curve.

f. Pipeline. A temporary pipeline will transport the dredged
material from the dredging sites to the beach disposal sites. A booster
pump may be required due to the pipeline length. A feeder pipeline will
extend from the dredge parallel to the AIWW channel connecting to a
pipeline that crosses to the ocean beach disposal area. After crossing the
beach dunes, the pipeline will extend parallel to the beach as needed to
distribute the discharged material. Possible pipeline routes are shown on
Figures 2-4, however, other pipeline routes may be used following
coordination with individual landowners, local governments, and State and
Federal environmental agencies. Easements will be required for the
pipeline crossing public or private lands. The easement requirement will
insure that concerns of individual landowners regarding pipeline impacts on
their properties are addressed before pipeline placement occurs. It is
expected that a single pipeline will follow, where possible, cleared road
right-of-ways, utility easements, or navigation canals. The pipeline will
not block use of roads, driveways, or navigation canals. Where the
pipeline crosses the marsh, joints will be burlapped and welded to provide
protection from leakage.
Heavy equipment will be used for the placement and alignment of the
pipeline on land. Accordingly, the pipeline route easements must be wide
enough to allow equipment passage. Where the pipeline follows the AIWW or
tidal watercourses, the pipeline will be positioned by the dredge-tending
workboats or floated and pulled by cable from the nearest accessible high .
ground. '

2. ALTERNATIVES
The alternatives to dredging of the AIWW were addressed in the
previously referenced AIWW FEIS filed with CEQ in 1975. Major alternatives
were to continue dredging or no action. Without dredging (no action)
shoaling in the AIWW would make the waterway unusable to many types of
recreational and commercial vessels.
Alternative methods of dredged material disposal include: diked upland
disposal and open-water disposal within adjacent estuarine waters.
a. Diked Upland Disposal. Existing diked upland dredged material
disposal areas adjacent to these sections of the AIWW are nearly full.
Locating the acreage needed for upland disposal area(s) within these
predominately estuarine wetland areas would have greater adverse
environmental impacts than the proposed beach disposal.
b. Open-water Disposal. Confined or unconfined thin-layer open-
water disposal within adjacent estuarine waters is an alternative to beach
disposal. These alternatives were not selected as the environmental
impacts to estuarine resources of in-water disposal were considered greater
than the impacts resulting from beach disposal of the dredged material.
3.
ENVIRONMENTAL EFFECTS
The environmental effects of dredging the specified portions of the
AIWW were addressed in the previously referenced Maintenance of the AIWW
FEIS (filed with the CEQ on November 21, 1975). This environmental
assessment will address the disposal of dredged material on beaches at
Topsail Beach-Surf City, West Onslow Beach, and Onslow Beach.
a. Water Quality. The North Carolina water quality classification
assigned to the portions of the AIWW addressed by this environmental
assessment is SA (15 NCAC 2B .0311 and .0312). The Atlantic Ocean waters
in the vicinity of all the proposed beach disposal areas are classified SB.
SA waters are suitable for commercial shellfishing and all other tidal salt
water uses including swimming, primary and secondary recreation, and fish
propagation. SB waters are suitable for swimming, primary and secondary
recreation, and fish propagation.
Several point source discharges occur in streams draining into the AIWW
and New River. Other pollution sources include leakage from faulty
operation of septic tanks and leaching fields and sewage discharge from
commercial and pleasure boats, and urban and rural runoff. However, waters
of this area generally meet the designated classification, although there
are areas of localized degradation, depending on proximity to human
settlements, as is evidenced by the "closed to shellfishing" signs along
the AIWW.
The western 8,900 feet of the New Topsail Inlet crossing of the AIWW
(Section III, Tangent 8) extends through waters which are additionally
classified as outstanding resource waters (ORW) in accordance with 15 NCAC
2B .0216. The ORW classification is assigned to waters which are of
5
exceptional recreational or ecological significance. The proposed
maintenance dredging and beach disposal will maintain existing uses of
these waters and will not have significant adverse effects on their
recreational or ecological significance. The dredging activity within the
ORW will produce only temporary and short-term changes in water quality,
which will not affect existing uses. The proposed dredged material
disposal on Topsail Beach - Surf City will occur outside of the ORW area.
With the exception of the Hurst Beach prohibited area (an area closed
to shellfishing), all AIWW areas where the dredging will take place and the
Atlantic Ocean immediately adjacent to the disposal beaches are open to
shellfishing. The southwest end of AIWW Section II Tangent F (Bear to
Browns Inlet crossing area) extending to approximately 3000 feet northeast
of the Hurst Bridge is included in the Hurst Beach prohibited area. As the
waters affected by the discharge of dredged material, the Atlantic Ocean,
are classified SB and therefore are not available for commercial
shellfishing, the dredged material from the aforementioned closed
shellfishing area can be discharged without adversely affecting shellfish
resources. This determination has been coordinated with the N.C. Division
of Health Services, Shellfish Sanitation Office, Morehead City, North
Carolina.
Increases in nearshore turbidity will be caused by dredge slurry
entering ocean waters and winnowing of fines by wave and current action.
However, significant increases in turbidity will not occur outside the
immediate beach discharge area (turbidity increases of 25 NTU's or less are
not considered significant). Turbid waters (increased turbidity relative
to background levels but not necessarily above 25 NTUs) will hug the shore
and be transported with waves either east or west depending on wind
conditions.
The proposed dredging and beach disposal will not produce adverse
impacts to groundwater resources.
b. Marine Resources. The impacts of beach disposal on marine
resources would be minor and confined to the immediate vicinity of the
disposal area and the timeframe in which the disposal occurred. Intertidal
benthic inverterbrates, including mole crabs, coquina clams, amphipods,
isopods, and polychaetes, will be covered by dredged material in the beach
disposal area. Some burrowing up through overburden will occur.
Recolonization would be expected to begin as soon as the disposal operation
ends. These invertebrates serve as an important food source for surf-
feeding fish and shore birds. Other than temporarily affecting benthic
food sources in the immediate disposal area, no adverse effects to fishes
should be expected in the vicinity of the dredging and disposal activities.
c. Estuarine Resources. The environmental impacts of the dredging
on shallow water, estuarine resources were addressed in the previously
referenced AIWW Maintenance Dredging FEIS, November 1975.
Beach disposal will not require the filling of wetlands although the
dredge pipeline may cross over high and low marsh to reach the beach
disposal area. Where the pipeline crosses the marsh, joints will be
burlapped and welded to provide protection from leakage.
d. Terrestrial Resources. Topsail Island, which includes the
Topsail Beach-Surf City and West Onslow Beach disposal areas, and Onslow
Beach are both separated from the mainland by marshes, sounds, and the
AIWW. Terrestrial resources on these beaches in the vicinity to be
traversed by the dredge pipeline and the proposed disposal area include
areas characterized by commercial and residential development; maritime and
pine forests; mixed shrub thickets; relict beaches; and beach dunes. The
beach disposal area, which is seaward of the primary dunes, consists
primarily of bare sand. However, vegetation in the disposal area may
include beach spurge, sea rocket, panic grass, sea purslane, pennywort, and
pigweed.
Impacts to terrestrial resources are expected to be primarily due to
pipeline placement and discharge of dredged material. The disposal area
may also be impacted by the grading of the discharged dredged material by
heavy equipment. Possible pipeline routes have been shown on Figures 2-4
but others may be used following coordination with local municipalities.
Easements will be required for the pipeline crossing public or private
lands. It is expected that the pipeline will follow, where possible,
cleared road right-of-ways, utility easements, or navigation canals. No
areas of maritime forest will be affected by the pipeline route. If dune
vegetation is disturbed by the pipeline or equipment crossing to the beach,
those areas will be restored to pre-project grade and replanted following
project completion. The actual discharge of material will occur on the
beach area between the water and the seaward toe of the primary dune. The
discharge of dredged material may bury some pioneer vegetation in front of
the dunes.
Amaranthus pumilus (seabeach amaranth or pigweed) is an annual or
perennial plant that usually grows between the seaward toe of the dune and
the mean high water line. The plant is listed by the North Carolina
Department of Agriculture, Plant Conservation Program, as threatened
(revised July 1987). The plant is a candidate for addition to the U.S.
Fish and Wildlife Service's (USFWS) List of Endangered and Threatened
Plants (50 FR 188, p. 39527). The USFWS encourages consideration of
candidates in environmental impact analysis under the National
Environmental Policy Act of 1969, as amended.
Greatest concentrations of Amaranthus pumilus occur near inlet areas of
barrier islands; however, plants can occur away from inlet areas. A.
pumilus occurred on Topsail Beach, West Onslow Beach, and Onslow Beach in
1989 (Personal Communication, January 3, 1989, Allan Weekly, N.C. Natural
Heritage Program). The avoidance of dredged material placement along inlet
shoulders (shore areas adjacent to the inlet) will minimize impacts to
Amaranthus up milus to the maximum extent practicable. Disposal of dredged
material on the proposed beach disposal areas may cover some Amaranthus
pumilus. However, a widening of the beach, or the making of a more gentle
beach profile may make more habitat available to the plant between beach
disposal events thus having a beneficial effect.
7
e. Endangered and Threatened Species. Informal consultation was
initiated with the National Marine Fisheries Service and the U.S. Fish and
Wildlife Service on August 3, 1989. Those agencies provided the following
list of endangered (E) and threatened (Th) species which may occur in the
project area and must be considered.

. Except for the piping plover and the loggerhead and green sea turtles,
the species listed above are not known to frequent the areas which would be
impacted by the proposed AIWW dredging and beach disposal.
The whales have been documented from North Carolina in the waters off
the coast outside of the project impact zone (Cooper et al., 1977).
A resident population of the shortnose sturgeon is not likely to be found
in the project area because there is no large river nearby which can
provide all of the life history requirements of the species.
The roseate tern is most frequently found in North Carolina as a
transient between March and mid-May in the spring and late-July to October
in the Fall (Potter et al., 1980). Currently, nesting by this species in
the U.S. is restricted to isolated locales in New England and Florida. Due
to the nonbreeding status in the proposed beach disposal area and the
abundance of nearby habitat which will be unaffected by the beach disposal,
the proposed beach disposal should not affect the roseate tern.
Bald eagles and peregrine falcons would be expected to occur only as
migrants or winter residents in the project area. Due to their mobility,
proposed dredging and dredged material disposal activities should not
effect these species. The red-cockaded woodpecker is a resident of mature
pine forests of the project region. No pine forest habitat will be
affected by the proposed dredging and dredged material disposal; therefore,
the red-cockaded woodpecker will not be affected.
8
The only sea turtles known to frequent Topsail-Surf City, West Onslow,
and Onslow Beaches and vicinity are the loggerhead sea turtle and the green
sea turtle. The loggerhead sea turtle nesting has been documented on all
the beaches proposed for dredged material disposal (Henson, 1989). Green
sea turtles are also known to nest sporadically along the North Carolina
coast. Green sea turtle nestings have been documented on Onslow Beach.
The leatherback, hawksbill and Kemp's ridley sea turtles are infrequent
visitors to the project area with no known nesting records on the beaches
proposed for use as dredged material disposal areas.
Loggerhead, green, and Kemp's ridley sea turtles may enter the AIWW
areas previously specified for dredging to feed. Pipeline dredges, the
type of dredge used for the proposed maintenance dredging, are not known to
take sea turtles. Therefore, the proposed dredging should not affect sea
turtles.
Dredging and beach disposal will be targeted to take place between 16
November and 30 April of any given year, to the maximum extent practicable,
to avoid impacts to nesting loggerhead and green sea turtles. While timing
these activities to avoid the nesting season is the method of choice for
avoiding impacts to nesting sea turtles, experience with similar projects
in North Carolina indicates that work during the nesting season will
eventually be necessary. When such occasions arise, a sea turtle nest
monitoring and relocation program will be implemented. This program has
been approved by the US Fish and Wildlife Service and consists of daily
monitoring of the beach impact area with relocation of all nests discovered
to a safe hatchery area. However, because of possible egg breakage or
reduced hatching success due to problems incurred during or as a result of
nest relocations, the proposed beach disposal of dredged material may
affect loggerhead and/or green sea turtles if project maintenance overlaps
the nesting season. All necessary State permits to perform the sea turtle
monitoring plan will be obtained from the North Carolina Wildlife Resources
Commission prior to plan implementation.
The piping plover is a fairly common winter resident along the beaches
of North Carolina from early August to late May and is known to nest in low
numbers in widely, scattered locations on North Carolina beaches (Potter et
al., 1980). The species normally nests on Atlantic coast beaches between
April 1 and July 31. In 1989, the piping plover was documented to have
nested on Topsail Beach in the overwash area very near New Topsail Inlet.
This was the first known nesting of the species on this beach.
Beach disposal of dredged material will cover intertidal organisms,
resulting in a reduction of food organisms for the piping- plover. These
losses of food would be temporary as recolonization by the food organisms
would be expected to begin as soon as the dredged material deposition ends.
Beach disposal of dredged material will occur primarily during the
winter months but may extend into the piping plover nesting season (April 1
through July 31). Adverse impacts to piping plover nests resulting from
beach disposal is not expected as the only known nesting area in the three
proposed beach disposal areas is in the overwash area very near New Topsail
Inlet and dredged material disposal will occur at least 3000 feet to the
northeast of the inlet. Equipment needed for disposal activities will not
9
be allowed in the New Topsail Inlet overwash area. Therefore, the proposed
beach disposal of dredged material should not affect the piping plover.
In conclusion, the only effects on endangered species which may occur
as a result of the proposed maintenance dredging and beach disposal are
effects which may occur when beach disposal takes place during the
loggerhead and green sea turtle nesting season. As a result of potential
effects of the proposed project on the loggerhead sea turtle and the green
sea turtle, formal consultation with the USFWS in accordance with the
provisions of Section 7 of the Endangered Species Act of 1973, as amended
is required and is ongoing. The formal consultation must be completed
before the proposed dredging and disposal can occur.
d. Archeological/Historical Resources. No archeological/
historical resources will be affected by the proposed maintenance dredging
and discharge of dredged material on the beach. The area to be dredged is
a previously dredged channel. Should unanticipated cultural remains be
encountered during the proposed maintenance dredging and beach disposal or
should previously undisturbed bottoms require dredging, they will be
evaluated pursuant to federal agency responsibilities under Section 106 of
the National Historic Preservation Act of 1966, as amended, and appropriate
action taken.
e. Recreation and Aesthetic Resources. The Topsail Beach - Surf
City and West Onslow Beach areas proposed for beach disposal of dredged
material are extensively used for recreational activities such as swimming,
walking, sunbathing, and fishing. The ocean, beach, dunes, and beach
vegetation offer natural scenery which.is aesthetically appealing to many.
These activities have large seasonal fluctuations with peak use occurring
in warm months. In the fall, recreational surf fishing is extensive.
Off-road vehicles are allowed on the beach within the proposed Topsail
Beach - Surf City and West Onslow Beach disposal areas during periods
specified by the local governments, generally between mid-September and
mid-May. Heavy equipment, the pipeline, and the discharge of dredged
material on the beach will temporarily disrupt recreational use of the
beach. The pipeline, equipment, and the newly discharged dredged material
will contrast to the natural surroundings and the coastal view. Since
disposal would occur during the off-peak period for most activities, late
fall/winter or early spring, the impacts to beach recreation and aesthetics
are expected to be short term and minor. The dredged material to be
discharged contains small percentages of silt and clay. This fine grained
material will not be retained in the beach profile but will be quickly
winnowed by wave action. However, the appearance of the beach will likely
be temporarily degraded. Disposal will result in-a temporary widening of
the beach. Surf fishing will not be precluded by the beach disposal except
possibly in a small area in the immediate vicinity of the discharge pipe.
Adverse impacts to recreational fishing in the beach disposal areas should
be temporary and minor.
A dredge and associated equipment are periodically seen in New Topsail '
Inlet, Banks Channel, and Topsail Beach during maintenance of the existing
navigation channels with dredged material disposal on the ocean shore at
Topsail Beach. These activities have not had significant adverse impacts
to recreational and aesthetic resources on Topsail Beach.
10
Onslow Beach is a part of the Marine Corps Base, Camp Le,jeune and is
used for amphibious assault training including mechanized training. Also
in con,juction with military training at Camp Le,jeune, the northern portion
of Onslow Beach, from the Onslow North Tower to Browns Inlet is a part of
the N-1 Impact Area (Browns Island Target and Bombing Area BT-3)• The
Hurst Beach area, approximately midway between New River and Browns Inlets,
has administration and recreation areas. The use of Onslow Beach for
dredged material disposal will not affect recreational or other uses of
this area.
4. RELATIONSHIP TO COASTAL ZONE MANAGEMENT LAND USE PLANS
The Coastal Area Management Act (CAMA), land use plans applicable to
the proposed beach disposal areas are as follows:
Beach Disposal Area Land Use Plan Plan Date
Topsail Beach-Surf City Town of Surf City, N.C. September 1987
(New Topsail Inlet Crossing) Town of Topsail Beach, N.C. February 1986
West Onslow Beach Onslow County March 1987
(New River Inlet Crossing)
Onslow Beach Not Applicable/Federal Land
(Bear to Browns Inlet Crossing)
The Topsail Beach - Surf City beach disposal area is classified as
conservation - public access. The pipeline transporting the sand from the
dredging site to the beach would likely cross lands classified as developed
and conservation. For West Onslow Beach, the Onslow County Land Use Plan
indicates that the land classification of the proposed beach disposal area
is higher density transition. The pipeline transporting the sand from the
dredging site to West Onslow Beach would likely cross lands classified as
higher density transition and conservation. The above referenced land use
plans contain policy statements which support dredging to maintain
navigable channels and beach nourishment (beach deposition of dredged
material).
The proposed dredging and dredged material disposal will-not result in
significant adverse effects to the beach, therefore, the proposed action
does not conflict with the applicable land use plans.
The proposed AIWW maintenance dredging and beach disposal will take
place within 2 categories of Areas of Environmental Concern (AECs), the
estuarine system and ocean hazard system, as designated by the Coastal
Management Program of the State of North Carolina. Specifically, the AIWW
maintenance dredging will take place within the estuarine waters and public
trust areas AECs (estuarine system). The dredge pipeline will cross
estuarine waters, estuarine shorelines, coastal wetlands, and public trust
area AECs (estuarine system). The proposed beach disposal areas are within
the ocean erodible area and the high hazard flood area and inlet hazard
area (for Topsail Beach only) AECs (ocean hazard system).
The proposed dredging will maintain the navigability of the AIWW. The
dredging and disposal will not be detrimental to the biological and
physical functioning of the

Based on the information presented within this environmental
assessment, the proposed AIWW maintenance dredging and beach disposal on
Topsail Beach - Surf City, West Onslow Beach, and Onslow Beach are
consistent with the approved Coastal Management program of the State of
North Carolina.
5. ENVIRONMENTAL REQUIREMENTS
A Section 401 (P.L. 95-217) Water Quality Certificate will be requested
from the North Carolina Division of Environmental Management for the
disposal of dredged material from the AIWW on beaches as previously
described. A Section 404(b)(1) (P.L. 95-217) Evaluation and Findings of
Compliance will be prepared for the beach disposal prior to the discharge.
The proposed AIWW maintenance dredging and beach disposal are located
within the flood plain. The proposed activities maintain navigability and
help minimize the impacts of floods on human safety, health, and welfare.
In order to assure navigability of the AIWW, the proposed activity must be
located in the flood plain. Accordingly, the requirements of Executive
Order 11988, Floodplain Management, are met.
The proposed AIWW maintenance dredging and beach disposal will not
require dredging or filling of any wetlands. The discharge pipeline may
cross wetlands to reach the beach disposal sites. Where the pipeline
crosses wetlands, pipeline joints will be welded and burlapped to provide
protection from leakage. Wetland impacts will be minimized to the maximum
extent practicable as required by Executive Order 11990, Protection of
Wetlands.
The material to be dredged is sand which is acceptable for beach
deposition. The presence of extensive estuarine wetlands adjacent to the
AIWW limits the availablity of disposal alternatives other than beach
disposal for the AIWW sections described. The disposal of AIWW dredged
materials in areas adjacent to the channel would likely have greater
adverse impacts on wetlands than the proposed beach disposal. Accordingly,
no dredged material will be used for construction of wetlands under the
provisions of Section 150 of the Water Resources Development Act of 1976
(PL 94-587).
Portions of the proposed beach disposal areas on West Onslow Beach and
Onslow Beach are within the Onslow Beach (L05) and Topsail (1,06) units,
respectively, of the Coastal Barrier Resources System established pursuant
to the Coastal Barrier Resources Act of 1982 (CBRA) (P.L. 97-348). The
1988 Report to Congress: Coastal Barrier Resources System, Volume 11
published by the Coastal Barriers Study Group, U.S. Department of the
Interior recommended that Unit L05 be deleted from the Coastal Barriers
12
Resources System (CBRS), however no
recommendation.

Grain Size Distribution of Channel Sediments
AIWW, New Topsail-, New River, and Bear to Browns Inlet Crossings
Sediment samples were collected using a Petersen grab sampler for all
samples except those from AIWW Section III Tangent F. Because of concerns
for unexploded ordnance, samples from Tangent F were collected by shovel
from dredged material deposition areas adjacent to the AIWW channel.
Tangent F had been dredged approximately two weeks prior to the sediment
sampling date. Figures 2-4 indicate the sample locations. Stations were
positioned by reference to navigation day markers and by estimating the
distance between the markers. The fathometer was used to ensure that
samples were taken within the dredged channel, however within channel
location, i.e. mid-channel or right-left of center, varied with each
sample.
Sediment samples were sent to the U.S. Army Corps of Engineers' South
Atlantic Division (SAD) Laboratory in Marietta, Georgia for grain size -
sieve analysis.
The results of grain size analyses are summarized in Table A-1.

A review of the NEPA Document
indicates that:
a. The discharge represents the least
environmentally damaging
practicable alternative and if in
a special aquatic site, the
activity associated with the
discharge must have direct access
or proximity to, or be located in
the aquatic ecosystem to fulfill
its basic purpose (if no, see
section 2 and information
gathered in the NEPA document);
b. The activity does not:
1) violate applicable State water
quality standards or effluent
standards prohibited under Section
307 of the CWA; 2) jeopardize the
existence of federally listed
endangered or threatened species
or their habitat; and 3) violate
requirements of any federally
designated marine sanctuary (if
no, see section 2b and check
responses from resource and water
quality certifying agencies);
c. The activity will not cause or
contribute to significant
degradation of waters of the U.S.
including adverse effects on human
health, life stages of organisms
dependent on the aquatic
ecosystem, ecosystem diversity,
productivity and stability, and
recreational, esthetic, and economic
values (if no, see section 2);
d. Appropriate and practicable steps
have been taken to minimize
potential adverse impacts of the
discharge on the aquatic
ecosystem (if no, see section 5).

*A negative, significant, or unknown response indicates that the permit
application may not be in compliance-with the Section 404(b)(1) Guidelines.
1/ Negative responses to three or more of the compliance criteria at this stage
indicate that the proposed projects may not be evaluated using this "short form
procedure." Care should be used in assessing pertinent portions of the
technical information of items 2 a-d, before completing the final review of
compliance.
2/ Negative response to one of the compliance criteria at this stage indicates
that the proposed project does not comply with the guidelines. If the
economics of navigation and anchorage of Section 404(b)(2) are to be evaluated
in the decision-making process, the "short form evaluation process is
inappropriate."
3/ If the dredged or fill material cannot be excluded from individual testing,
the "short-form" evaluation process is inappropriate.
