SUBJECT: Battery Island Bird Preserve Beach Restoration/Stabilization (Scoping Letter Comments)
(DENR# 98-0466, DWQ# 11941)
Based on a review of the January 23, 1998 scoping letter regarding the preservation and stabilization of
Battery Island the 401/Wetland Group offer the following comments:
1) The project (as detailed in the letter) proposes to install rock riprap, geo-tubes, treated wood, or sheet
piling bulkheads along the Battery Island shoreline and then backfill landward of these structures with
an estimated restored area of 5.7 acres. DWQ will require information regarding the current state of
these eroded areas (i.e., are they now coastal marsh?, are they SAVs?, are they shallow water?, are
there shellfish in these areas?, etc... ). These questions must be addressed in future correspondences.
2) If there are habitat types as discussed above, then DWQ would likely require minimization/avoidance
measures to be taken. For instance is all 5.7 acres of nesting habitat to be restored necessary to
maintain current or past levels of birds? Would less than 5.7 acres of restoration still accomplish the
same goal? Would stabilizing the island at its current areal extent (without restoration) still support a
vigorous avian community similar to pre-erosion levels? Data demonstrating a decline in population
and/or recruitment of nesting (and non-nesting) birds related to the loss of the 60 feet of shoreline (and
the corresponding loss of nest-supporting red cedars/ yaupons) would be extremely useful.
3) Since Battery Island is a Bird Preservation/Nature Reserve, DWQ would recommend the use of
bioengineering practices as much as possible for the stabilization/restoration efforts to maintain
continuity and consistency with the Island's natural heritage.
If there are any questions regarding this matter, please feel free to call at (919) 733-1786.

COASTAL MANAGEMENT
Dear Madam or Sir:
We are conducting studies for the preparation of an Environmental Assessment
(EA) for the proposed restoration and preservation of the bird habitat on Battery Island,
near Southport, Brunswick County, North Carolina.
Battery Island (see figure 1) is located in the Cape Fear River, approximately
0.5 mile east of Southport and 24 miles south of Wilmington, North Carolina. Battery
Island is adjacent to the navigation-channel and is approximately.100 acres in total
area. Two upland bird nesting areas exist (see figure 2). The "North Colony," area is
approximately 3 acres and is vegetatived with live oak (Quercus virginiana), yaupon
(Ilex vomitoria), red cedar (Juniperus virginiana) and marsh elder (Iva frutescens).
The "South Colony, area is approximately 7 acres and is vegetatived with red cedar,
yaupon, marsh elder, Hercules club (Xanthoxylum clava-herculis), black cherry (Prunus
serotina), and white mulberry (Morus alba). The remainder of the island is saltmarsh
dominated by cordgrass (Spartina alterniflora). The North Colony is natural but
appears to have been modified in the past by placement of dredged material. The
South Colony was created by undiked deposition of dredged material. The island has
not received any dredged material in at least 25 years.
Battery Island is widely recognized as an avian landmark and is considered.to be
the largest heronry in North Carolina. Located in the lower Cape Fear River, east of
Southport, this island is a haven for birds throughout the year, but it is most noted for
the long-legged waders that occupy the island during the spring and summer months.
Each spring, thousands of wading birds (herons, egrets, and ibises) gather on the
island to nest and to raise their young. This annual rite of spring has taken place.since
at least 1928, when wading birds were first reported nesting on the island. Batt ery
Island is the only nesting site within 100 miles (between Bogue Sound, North Carolina,.
and the North Carolina/South Carolina State line) that is capable of supporting such a
-2-
large colony of wading birds. Moreover, the island supports ten species of wading
birds, three of which are state-listed as species of special concern"- little blue,heron,
snowy egret, and glossy ibis. In addition, Battery Island supports over 90 percent of
North Carolina's nesting white ibises.
Battery Island is owned by the State of North Carolina. Since 1992, the National
Audubon Society has a long-tern (50-year) lease on this site and maintains it as a
sanctuary. Battery Island is a protected Colonial Waterbird Management Site. The
island is posted off-limits to all visitors from March 1 to September 1 and is patrolled
throughout the year. At other times of the year, activities that would jeopardize the
nesting habitat are prohibited (i.e., fires, camping, cutting or removal of vegetation,
etc.).
In recent years, Battery Island's southern and western shorelines have
experienced severe erosion. It is estimated that up to 60 feet of the southern and
western shorelines of the island have been lost in the past 5 years (since about 1993).
This equates to an average rate of erosion of about 12 feet per year. The erosion has
already claimed red cedars and yaupons that once supported nesting wading birds,
and other areas are threatened. Moreover, erosion has also claimed most of the beach
where oystercatchers once nested. Stabilization of Battery island's shoreline is
necessary to prevent the further loss of this valuable bird nesting habitat.
With the cooperation of the National Audubon Society, the Wilmington District,
U.S. Army Corps of Engineers, and the North Carolina Department of Environment
and Natural Resources, Division of Water Resources, are planning to stabilize and to
restore the western and southern shorelines of Battery Island to its condition prior to
1993. Methods of stabilization may include (but not limited to) the construction and/or
installation of rock riprap, geo-tubes (large sand bags), treated wood, or sheet piling
bulkheads (see figure 2). Once the retaining wall has been constructed, the area
landward of the wall will be backfilled. The project may restore up to. 5.7 acres of
valuable colonial bird nesting habitat.
We are requesting comments from agencies,. interest groups, and the public to
identify significant resources, issues of concern, and recommendations for studies
considered necessary. Comments received, as a result of this scoping letter, will be
considered as we conduct our studies and identify potential impacts on environmental
quality. These items will be addressed, as needed, in the EA.
-3-
Significant resources which may be affected by the proposed project may include
historic resources, recreational and esthetic resources, endangered and threatened
species, fish and wildlife resources, water quality, and estuarine and upland habitats.
These resources will be considered during the National Environmental Policy Act
(NEPA) process. No formal scoping meetings are planned at this time. However,
based on the responses received, scoping meetings may be held with specific agencies
or individuals as required.
We request that you provide written comments on any of these matters within
30 days from the date of this letter. Comments should be addressed to Mr. Hugh
Heine, U.S. Army Corps of Engineers, Wilmington District, Post Office Box 1890,
Wilmington, North Carolina 28402-1890. If you have any questions, please contact
Mr. Heine at (910) 251-4070 or e-mail address hugh.heine@saw02.us2ce.army.mil.

MAINTENANCE DREDGING OF AVON HARBOR
DARE COUNTY, NORTH CAROLINA
DECEMBER 1997
1.00 INTRODUCTION
Avon Harbor, located in Pamlico Sound, along the Outer Banks of North Carolina,
requires maintenance dredging to restore the harbor to its previously authorized project
depth (Figure 1). The dredged material will be placed in the upland diked disposal site
(Figure 2) that was addressed in the Environmental Assessment.. Maintenance
Dredging Of Avon Harbor Dare County North Carolina, October 1997.
2.00 DESCRIPTION OF PROPOSED ACTION
The proposed action involves the maintenance dredging of shoals lying above the
plane of 8 feet below mean low water (m.l.w.)(-6 feet m.l.w. plus 2 feet) within the
designated limits of the authorized basin, out to navigation beacon No. 8 (entrance
channel). Dredging will be accomplished by a hydraulic pipeline dredge. The-dredged
material, which consists of approximately 20,000 cubic yards of inorganic silt, will be
discharged into the upland diked disposal site. Dredging will take place between
November 1 and February 28 of any given year to minimize impacts to significant
resources.
Bottom sediments from Avon Harbor. were sampled on July 29, 1994, to make a
determination regarding the suitability of dredged material for beach disposal. Grain
size analysis indicated that sediments from Avon Harbor contained approximately 31
percent sand, were fine-grained, and considered unacceptable for beach disposal. For
this reason, all dredged material from Avon Harbor will be placed in the designated
upland diked disposal site (Figure 2).
The proposed upland diked disposal site is approximately 3 acres in size. The
dike surrounding the upland disposal site will be approximately 6 feet above m.l.w. and
will be constructed in a manner to guarantee a minimum of 2 feet of freeboard during
operations. The dike will be seeded and grassed in accordance with a Sedimentation
and Erosion Control Plana
Equipment (bulldozers, etc.), which may be required for construction of the dike,
including the placement of an effluent weir and outlet pipe, will be on- and off-loaded so
as to avoid impacts to wetlands. The effluent pipe will be extended waterward of
National Marine Fisheries Service, letter of October 20, 1997
COMMENT: Since the dredging will be accomplished by use of a pipeline dredge with
upland disposal, the impacts on fishery resources should be minimal. The EA
adequately describes the impacts of this project on fishery resources under our
purview. Therefore, we will offer no further comments or recommendations.
RESPONSE: Noted.
U S Environmental Protection Agency, letter of October 27, 1997
COMMENT: Given the biological importance of the submerged aquatic vegetation
(SAV) habitat and its potential for even incidental harm from this project, we believe that
the District should formulate the deliverables of the construction contract such that
bidders will be required to protect this valuable resource by all practicable means.
RESPONSE:. See attachment 2, which contains an excerpt from the U. S. Army Corps
of Engineers' specifications for maintenance dredging. Specifically, see Section 2.3.16,
Protection of Water Resources and Wetlands, Section 2.3.17, Protection of Fish and
Wildlife Resources, and Section 2.3.19, Protection and Restoration of Landscape and
Marine Vegetation Damages. In addition, a pre-work conference will be conducted.
The pre-work conference will give the contractor and representatives from the Corps an
opportunity to discuss important aspects of the project, such,as the protection of SAV.
During the conference, we will inform the contractor of the occurrence of SAV in the
project vicinity, its importance as a fishery habitat, and the importance of protecting the
habitat. Further, the contractor will be instructed to route pipelines, where practicable,
so as to avoid SAV.
COMMENT: The economic benefits associated with maintaining channel depths are
adequately explained; however, there needs to be some consideration given to the
natural environment, i.e., replacing the wetlands lost in constructing the disposal site.
Once again, we will leave the details as to how and where to best restore the functional
values of this vegetation type to your staff, but believe it should be done.
RESPONSE: We disagree. The isolated wetland that may be impacted by the project
is covered under Nationwide Permit #26, Headwaters and Isolated Waters Discharges.
Mitigation for this type of wetland is not required.
COMMENT: If groundwater movement is, in fact, from east to west, then contamination
of adjacent wells should not be a problem. However, if problems do result, what are the
options for affected homeowners?
RESPONSE: As was stated in the EA, past groundwater monitoring indicates that
groundwater flow is from east to west. Therefore, the probability of the project
impacting groundwater resources is very, very remote. In addition, to date, there are no -
homes in the project vicinity that obtain their water from shallow water wells.
COMMENT: With these enjoinders in effect coupled with the absence of any other
apparent and/or compelling adverse effects attendant to the action we have no
significant objections to the use of an EA as the evaluation model rather than the more
comprehensive environmental impact statement format.
RESPONSE: Noted.
Department of Health and Human Services, letter dated November 5, 1997
COMMENT: We believe our potential concerns have been generally addressed in this
EA, and we concur with the recommended activities and the FONSI.
RESPONSE: Noted.
North Carolina Department of Cultural Resources, letter dated November 12, 1997
COMMENT: In our underwater research files we have references to extensive maritime
activities and shipwreck losses in the general vicinity; therefore, much of the project
area holds a high potential for containing submerged cultural resources. However,
since this project concerns maintenance dredging within controlled and previously
dredged channels, we recommend no archaeological investigation be conducted.
RESPONSE: Agreed.
COMMENT: We would like to notify you that this project should be undertaken with
caution. If during construction submerged archaeological materials are encountered,
such as shipwreck remains, it is the responsibility of the Army Corps of Engineers-
Wilmington District to notify this office immediately, pursuant to Section 106 of the
National Historic Preservation Act of 1966.
RESPONSE: Agreed. As stated in Section 01430, Environmental and Cultural
Resource Protection, of the Corps' specifications for maintenance dredging, "in the
event that the contractor makes an unanticipated discovery or contact with a shipwreck
or other historic cultural resource, the Contractor will suspend dredging operations in
the vicinity of contact or discovery, will immediately record the location of the contact or
discovery, will immediately notify the Contracting Officer or designated representative,
and will preserve any recovered cultural material until it can be inspected by the
appropriate authorities." The Corps would then contact the North Carolina Department
of Cultural Resources, so that appropriate actions, pursuant to Section 106 of the
National Historic Preservation Act of 1966, as amended, could be initiated.

North Carolina Division of Water Quality, letter of November 18, 1997 -
COMMENT: The Division of Water Quality does not anticipate any major problems with
this project. Conditions likely to be included in the 401 Water Quality Certification
include routing the pipeline in such a manner so that it does not intersect any SAV's or
wetland areas.
RESPONSE: Noted. SAV's and wetlands will be avoided to the greatest extent
practicable.
North Carolina Division of Coastal Management, letter of November 13, 1997
COMMENT: The project proposal is consistent with the Dare County Land Use Plan,
both earlier and current County amended policy, the project is not in conflict with the
Land Use Plan.
RESPONSE: Noted.
North Carolina Wildlife Resources Commission, letter of November 12, 1997
COMMENT: Large areas of coastal marsh exist between Avon Harbor and the
proposed disposal site. The EA did not specify where the dredge pipeline would be
located and if it would impact wetlands. The EA did not indicate a retention time for the
disposal area or where the discharge pipe would be located.'' Review of this document
is incomplete without the above information but we will not oppose permit issuance as
long as the permit included the following conditions:
Any wetland impacted outside of the authorized nationwide permit 26 should be
returned to natural conditions immediately.
Adequate precautions should be taken to avoid turbidity plumes in Pamlico Sound.
RESPONSE. Due to the planned location of the dredge pipeline, the large areas of
coastal marsh that exist between Avon Harbor and the proposed disposal site will not
be impacted by the proposed project. In addition, no wetland outside the area
authorized by Nationwide Permit 26 will be impacted by the project. With regard to
pipeline placement, an unnamed creek, that is adjacent to the disposal site and which
flows into Pamlico Sound, will be used as the pipeline route. Specifically, plans are to
float the dredge pipeline from Avon Harbor, into Pamlico Sound, then south, toward the
unnamed creek (avoiding SAV where possible). The pipeline would then be floated up
the creek to a point adjacent to the disposal area. To get from the creek to the disposal
site, the dredge pipeline may cross over a narrow band of wetlands on the creek bank,
but this will not result in any placement of fill in the wetlands.
With regard to turbidity and retention time at the disposal site, North Carolina Water -
Quality Standards (15A NCAC 28.0200) require that turbidity in the receiving water
shall not exceed 25 NTU; if turbidity exceeds this level due to natural background
conditions, the existing turbidity level cannot be increased. The Corps' dredging
inspectors and the dredging contractors are aware of these requirements and will
regulate the retention time at the disposal site to ensure compliance.
North Carolina Division of Coastal Management, letter of December 2, 1997
COMMENT: The State of North Carolina has completed its review of the above
referenced proposal pursuant to 15 CFR 930 - Consistency of Federal Activities. Based
upon our review we agree with your determination that the proposed activity is
consistent with the North Carolina Coastal Management Program with the following
conditions. The conditions were agreed to verbally by Ms. Jenny Owens of your staff.
(See attached letter for conditions)
RESPONSE: Agreed. The conditions stated in your letter of December 2, 1997
(attachment 1), will be met.
6.00 ENDANGERED AND THREATENED SPECIES
As stated in the EA, the proposed work has been reviewed for compliance with the
Endangered Species Act of 1973, as amended, and informal coordination with the
USFWS has been completed. The USFWS has identified no endangered species,
threatened species, or critical habitats that will be affected by the proposed project.
Therefore, the requirements of the Endangered Species Act of 1973, as amended,
have been satisfied.
7.00 ENVIRONMENTAL COMMITMENTS
The following commitments must be fulfilled:
Maintenance of the project will be scheduled to be performed between November 1
and February 28 of any given year in order to minimize impacts to fishery resources.
SAV will be avoided to the greatest extent practicable.
A 401 Water Quality Certification for the proposed work will be obtained prior to
commencement of work.
6
8.00 ENVIRONMENTAL IMPACTS
There are no known areas of controversy or major unresolved issues associated
with the proposed action. Comments received during the coordination of the
referenced EA failed to note any additional categories of environmental impacts.
9.00 FINDING OF NO SIGNIFICANT IMPACT (FONSI)
The proposed action will not significantly affect the quality of the human
environment; therefore, an Environmental Impact Statement will not be prepared.

Attention Ms. Jenny Owens
Dear Colonel Youngbluth:
The National Marine Fisheries Service (N1V1FS) has reviewed Public Notice CESAW-TS-PE-98-28-
0002 dated October 8, 1997, and the Environmental Assessment (EA) for the maintenance dredging
of Avon Harbor, Dare County, North Carolina, dated October 1997. The project consists of the
maintenance dredging of the Avon access channel and harbor with the disposal of material into an
upland diked disposal site.
Since the dredging will be accomplished by use of a pipeline dredge with upland disposal, the impacts
on fishery resources should be minimal. The EA adequately describes the impacts of this project on
fishery resources under our purview. Therefore, we will offer no further comments or
recommendations.
We appreciate the opportunity to review this work. If we can be of further assistance, please advise.
Sincerely.

Subject: Environmental Assessment (EA) and Finding of No
Significant Impact (FONSI) for Maintenance Dredging of
Avon Harbor, Dare County, NC
Dear Colonel Youngbluth:
Pursuant to Section 309 of the Clean Air Act, EPA, Region 4
has reviewed the subject document which discusses the environmental
consequences of dredging shoals which have developed in and out to
beacon No.8 of the Avon Harbor. The 20,000 cubic yards of
inorganic silt will be deposited into an upland diked disposal
site. The channel restoration. will be accomplished by hydraulic
pipeline.
As we noted previously, dredging always has some adverse water
quality impacts. In this instance the proximity of submerged
aquatic vegetation (SAV) remains a matter of concern to us. Given
the biological importance of the SAV habitat and its potential for
even incidental harm from the total project, we believe that the
District should formulate the deliverables of the construction
contract such that bidders will be required to protect this
valuable resource by all practicable means. We are willing to
leave the details of how this will be accomplished to your staff
specialists, but would appreciate receiving a copy of the
stipulations for our review/comment prior to actual dredging.
We agree that the proposed upland disposal site is necessary
considering the fine grain nature of the excavated material.
Further, given the limited siting options available on barrier
features, we have no better suggestion for locating the site or
improving its design. The economic benefits associated with
maintaining channel depths are adequately expained; however, there
needs to be some consideration given to the natural
environment, i.e., replacing the wetlands lost in constructing the
disposal site. Once again, we will leave the details as to how and
where to best restore the functional values of this vegetation type
to your staff, but believe that it should be done. .

If groundwater movement is, in fact, from east to west, then
contamination of adjacent wells should not be a problem. However,
if problems do result, what are the options for affected
homeowners?
With these enjoinders in effect coupled with the absence of
any other apparent and/or compelling adverse effects attendant to
the action we have no significant objections to the use of an EA as
the evaluation model rather than the more comprehensive
environmental impact statement format.
Thank you for the opportunity to comment on this action. If
we can be of further assistance in this matter, Dr. Gerald Miller
(404-562-9626) will serve as initial point of contact.

We have completed our review of the Draft Environmental Assessment (DEA) and Finding of No
Significant Impact (FONSI) for Maintenance Dredging of Avon Harbor, Dare County, North
Carolina, October 1997. We are responding on behalf of the U.S. Public Health Service.
The purpose of this EA is to address the environmental impacts of the maintenance dredging of
Avon Harbor with disposal of material into an upland diked disposal site because this aspect of
the planned project was not addressed in the 1996 EA/Fonsi for maintenance dredging and,
dredged material disposal of the Rodanthe, Avon, and Rollinson Channels. We believe our
potential concerns have been generally addressed in this DEA, and we concur with the
recommended activities and the FONSI.
Thank you for the opportunity to review this draft document. We would appreciate receiving a
copy of the Final EA, and any future environmental impact statements which may indicate
potential public health impacts and are developed under the National Environmental Policy Act
(NEPA).

Dear Ms. Owens:
Division of Archives and History
Jeffrey J. Crow, Director
We have received notification from the State Clearinghouse and the Division of Coastal
Management concerning the U.S. Army Corps of Engineers proposal to perform routine
maintenance dredging of Avon Harbor
In our underwater research files we have references to extensive maritime activities and
shipwreck losses in the general project vicinity; therefore, much of the project area holds a
high potential for containing submerged cultural resources. However, since this project
concerns maintenance dredging within controlled and previously dredged channels, we
recommend no archaeological investigation be conducted.
We would like to notify you that this project should be undertaken with caution. If during
construction submerged archaeological materials are encountered, such as shipwreck
remains, it is the responsibility of the Army Corps of Engineers-Wilmington District to notify
this office immediately, pursuant to Section 106 of the National Historic Preservation Act
of 1966. In addition, the area is protected by North Carolina legislation (G.S. 121-22 to
28, Article 3: salvage of Abandoned shipwrecks and other underwater archaeological
materials on all bottoms from low water to one marine league seaward, and bottoms of
other navigable waters). This law is supported by the Abandoned Shipwreck Act of 1987
(P.L. 100-298) which gives the state jurisdiction over a broad range of living and nonliving
resources in state waters and submerged lands, including certain abandoned shipwrecks,
which have been deserted and to which the owner has relinquished ownership rights with
no retention.
Thank you for your cooperation and consideration. If you have questions concerning the
above comment, please contact Renee Gledhill-Earley, environmental review coordinator, at
919/733-4763.

Re: EA for Maintenance Dredging of Avon Harbor, Dare County, NC, October 1997
Dear Mrs. Baggett:
I have reviewed the EA for the maintenance dredging of Avon Harbor. I have no
comments or issues for this project. In addition to the EA. I have reviewed the Dare County
Land Use Plan QXP), as Certified by the NC Coastal Resources Commission on July 29, 1994.
In addition I have reviewed a recent Land Use Plan amendment adopted by the Dare County
Board of Commissioners on October 20, 1997. This amendment deleted policy associated with
freshwater wetlands, more particularly dropping any reference to isolated wetland pockets.
Land Use Plan Consistency Determination: The project proposal is consistent with the
Dare County Land Use Plan, both earlier and current County amended policy, the project is not in
conflict with the Land Use Plan.
Prior to the amendment, the County's LUP Land Classification Map designated the land-
ward portion of the project in the "Limited Transition" class, and "Limited Conservation" based
upon map text and classification description regarding freshwater wetland isolated pockets of less
than one acre in size.
Following the amendment the Classification Map, designates the site as "Limited
Transition" and "Conservation" per text on page 111, in the LUP. Per earlier and current County
policy, the project is not in conflict with the Land Use Plan.

DATE: November 12, 1997
SUBJECT: Environmental Assessment for the Maintenance Dredging of Avon Harbor, Town
of Avon, Dare County. Project # 98-E-0283.
Staff biologists with the Wildlife Resources Commission have reviewed the Environmental
Assessment. Our comments are provided in accordance with provisions of the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et. seq.), the Clean Water Act of
1977 (as amended) and the North Carolina Environmental Policy Act (G. S. 113A-1 et seq., as
amended; 1 NCAC-25).
The Town of Avon proposes to maintenance dredge Avon Harbor and the entrance
channel out to navigation beacon No. 8 to a depth of 8 ft. Approximately 20,000 yds' of silt
would be discharged into an upland diked disposal site. Dredging would take place between
November 1 and February 28 of any given year. Waters at the site are classified as SA.
Large areas of coastal marsh exists between Avon Harbor and the proposed disposal site.
The EA did not specify where the dredge pipeline would be located and if it would impact
wetlands. The EA did not indicate a retention time for the disposal area or where the discharge
pipe would be located. Review of this document is incomplete without the above information but
we will not oppose permit issuance as long as the permit includes the following conditions.
• Any wetland impacted outside of the authorized nationwide permit 26 should be returned
to natural conditions immediately.
• Adequate precautions should be taken to avoid turbidity plumes in Pamlico Sound.
Thank you for the opportunity to comment on this project. If you need to discuss these
comments please call William Wescott at (919) 927-4016.

2.3.18 PROTECTION OF ENDANGERED AND THREATENED SPECIES
Species listed as endangered or threatened receive a high level of protection under
the Endangered Species Act of 1973 (PL 93-205), as amended. Endangered or
threatened species, including whales, sea turtles, manatees, and shortnose sturgeon,
may be encountered in the project area during construction of this project. In addition, all
marine mammals, including porpoises and dolphins, are protected under the Marine
Mammal Protection Act of 1972 (PL 92-522), as amended_ Therefore, the Contractor shall
take such measures as may be required to assure that any activities conducted as a part
of this contract do not kill injure,
species. Specific types of equipment and operations pose different types of hazards, so
specific protective measures will vary depending upon the type of operation being
conducted. Protected species frequently occur in North Carolina waters and the
Contractor should plan the work accordingly.
NOTIFICATION AND REPORTING REQUIREMENTS FOR INCIDENTS INVOLVING
PROTECTED SPECIES - Incidents *involving the death or injury of any protected species
shall be reported to the Contracting Officer immediately. Also, the Contractor will prepare
and provide to the Contracting Officer written records detailing the incident within 24 hours
of its occurrence.
PROJECT SPECIFIC REQUIREMENTS - North Carolina beactvS are known to be used
for nesting by the loggerhead sea turtle, a federally listed threatened species. Should
work occur during the nesting season (May 1 thru November 15), the Contracting Officer,
under separate contract, will have sea turtle nest monitoring and relocation performed to =
minimize potential adverse impacts to this species. This separate contractor will be
traversing the entire project area daily to locate and remove sea turtle nests to a hatchery
outside of the project area.
Specific Contractor requirements for this project are as follows:
(a) Through the period of sea turtle nesting and hatching (May 1 through November
15), construction pipes that are placed parallel to the shoreline will be placed as far
landward as possible when passing over completed sections of the project.
Temporary storage of pipes and equipment shall be off the beach, but not in wetland
areas. If beach storage is considered necessary, prior approval will be obtained from the
Contracting Officer. If approval is granted, pipes and equipment shall be placed as far
landward as possible.
(b) During construction, visual inspections of the disposal areas will be conducted to
determine if escarpments greater that 18 inches high and 100 feet in length are present.
If escarpments exceeding these dimensions are found, and the elevation of the placed
material is within the maximum allowable elevation +6.0 feet NGVD (plus or minus 0.5
foot), the escarpment will be removed within 24 hours of receiving approval from the
Contracting Officer by forming a smooth slope from the top of the placed material to the
foreshore slope of the.placed material. If the elevation of the placed material exceeds the
maximum allowable elevation, material lying above the maximum allowable elevation will
be removed and redeposited within other sections of the designated disposal area and
within the allowable tolerances. NOTE: During the sea turtle nesting season,
escarpments may not be leveled until results of daily sea turtle monitoring have been
reviewed by the Contracting Officer and his approval granted for escarpment leveling.
Escarpment leveling may only take place during daylight hours.
(c) If, during the course of conducting work, a sea turtle nest is disturbed by
construction activities, the Contractor will mark the nest location and cover the eggs, by
hand, with at least 6 inches of sand. All beach disturbing activities will be stopped within a
100-foot radius of the nest to prevent further damage and the Contracting Officer notified
immediately. Work in this area will not resume until the nest has been relocated and the
Contracting Officer grants approval.
(d) During the period of sea turtle nesting and hatching (May 1 through November
15), all beach lighting associated with project construction shall be minimized to the
maximum extent practicable while maintaining compliance with all safety requirements.
Reduced wattage and special fixtures or screens to reduce illumination of adjacent beach
and nearshore waters shall be used if practical. Shielded low pressure sodium vapor
lights are recommended for all lights on the beach.
01430-9
(e) - If a dead, injured or sick sea turtle, or any other endangered or threatened
species is found in the project area by the Contractor, it must be left undisturbed and the
Contracting Officer notified immediately. -
2.3.19 PROTECTION AND RESTORATION OF LANDSCAPE AND MARINE
VEGETATION DAMAGES
The Contractor shall restore all landscape features and marine vegetation
damaged or destroyed during construction operations outside the limits of the approved
work areas. All landscape features damaged or destroyed during construction operations
that were not identified for removal shall be restored. Any vegetation or landscape feature
damaged shall be restored as nearly as possible to its original condition. This work will be
accomplished at the Contractor's expense.
2.3.20 ENVIRONMENTAL QUALITY CONTROL
The Contractor shall establish and maintain quality control for environmental
protection of all items in this section. The Contractor shall record on daily quality control
reports or attachments thereto, any problems in complying with environmental laws and
regulations, and corrective actions taken.
2.4 WORK AREA PLAN
The Contractor shall include a Work Area Plan showing the proposed activities in
each portion of the project area and identify the areas of limited use or nonuse. The Plan
shall include measures for marking the limits of use areas. The Contractor shall include
drawings identifying the areas of limited use or nonuse and show locations of any
proposed temporary excavations or embankments for haul roads, stream crossings,
material storage areas, structures, sanitary facilities, stockpiles of earth materials, and
disposal areas for excess earth material and unsatisfactory earth materials.
The Contractor's field offices, staging areas, stockpile storage, and temporary buildings
shall be designated areas on the drawings or as approved. Temporary movement or
relocation of Contractor facilities shall be only on approval by the Contracting Officer.
Prior to any construction, the Contractor shall mark the areas within the designated
work areas that are not required to accomplish work to be performed under this contract
and which are to be rotected. Isolated
be saved and protected shall be marked or fenced. Monuments and markers shall be
protected during construction. Where construction operations are to be conducted during
darkness, the markers shall be visible in the dark. The Contractor shall convey to his
personnel the purpose of marking and protection of all necessary objects.
2.5 POST CONSTRUCTION CLEANUP
The Contractor shall clean up areas used for construction and remove all signs of
temporary construction facilities; Contractor office, storage and staging areas; quarry and
borrow areas; and all other areas used by the Contractor during construction. Any
disturbed areas shall be graded and filled as approved by Contracting Officer.
