Dear Mr. & Ms. Harrell:
You have our approval, in accordance with the attached conditions and those listed below, to
place fill within or otherwise impact 0.062 acres of wetlands for the purpose of constructing a
single family residence at the subject property, as described `within your application dated June 1,
2004 and received by the N.C. Division of Water Quality (DWQ) on June 3, 2004. After
reviewing your application, we have decided that the impacts are covered by General Water
Quality Certification Number(s) 3402 (GC 3402). The Certification(s) allows you to use
Nationwide Permit(s) 18 when issued by the US Army Corps of Engineers (USACE). In
addition, you should obtain or otherwise comply with any other required federal, state or local
permits before you go ahead with your project including (but not limited to) Erosion and
Sediment Control, Non-discharge, and CAMA regulations. Also, this approval to proceed with
your proposed impacts or to conduct impacts to waters as depicted in your application
shall expire upon expiration of the 404 or CAMA Permit.
This approval is for the purpose and design that you described in your application. If you change
your project, you must notify us and you may be required to send us a new application. If the
property is sold, the new owner must be given a copy of this Certification and approval letter and
is thereby responsible for complying with all conditions. If total fills for this project (now or in
the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may
be required as described in 15A NCAC 2H .0506 (h). This approval requires you to follow the
conditions listed in the attached certification and any additional conditions listed below.

local stormwater requirement, etc.): N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The house location and driveway are constrained by the minimum building limits set the Town
of Nags Head. Several plans were created to fit the residential home and amenities on the lot, but
each plan resulted in an area which needed wetland fill to gain adequate setbacks for the sewage
disposal system, parking, and required setbacks. The attached plan represents the most desirable
option for the house and associated driveway and septic area.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
Page 5 of 5
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.html.

1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Mitigation will involve a proposed payment to the NC EEP for the impacted area
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. -Sew a_ / k p ed
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 9 of 12
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strm?,,ide.html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919) 733-5208 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):

A representative of the Dare County Health Department made an on-site visit to
the above referenced property. Our comments are indicated below:
IMPROVEMENT PERMIT
1. If an Improvement Permit is desired, a current registered survey is required
showing the property boundaries, purposed Io.oation of house or business (drawn
to scale), decks, driveway, parking area and any pertinent landscape feature,
easements or other factor that might effect the location and the function of the
septic disposal system. This permit becomes a non-expiring site approval for the
eventual installation of an on-site wastewater system. The Improvement Permit
shall not be effected by transfer of the property or change in ownership, provided
all of the specific conditions are met
A. This permit does not relieve you of any other State, Federal or Local Permit
that may be needed.

11_ If an Authorization for Wastewater System Construction (C.A.) is desired, any
required site/fill work must be completed and approved by this department. Two
(2) sets of house plans must be submitted. If the property is looted In an area
served by the Dare County Water System, proof of public water by a paid receipt
must be submitted. Finally, a copy of your Improvement Permit must be
submitted.

RECOMMENDATIONS:
The above referenced lot was evaluated and found to be provisionally suitable for
a septic system. The following requirements must be met before a permit can be
issued:
1. We will need a letter from a certified wetlands consultant or the Army
Corps of Engineers stating if this lot contains or does not contain any
'- - ----'- "--J`wetCands:?firvetl`?nds afe found; we'wriii riee??fie area sFia?vn-on a survey - - so proper separation can be maintained from them with the septic tank.
2. If no wetlands are found, we will need a survey showing the house
placement so the septic system location along with the fill area can be
designated. Twenty four inches (24") of fill will be needed in the septic
area.
3. The septic system will need to be located on the east side of the property.
4. We will need to review and approve your house plans.
Please contact our department if you have any questions.
In the event you disagree with these findings, you may request an informal
review by directing your written comments to: Dare-County Health Director, PO
Box 1000 nteo, NC 27954.

PROJECT DESCRIPTION
The development is a proposed 4-bedroom residence on the west
side of Old Oregon Inlet Road (NCSR 1243) in Nags Head.
There will be no on-site stormwater infiltration swales; all
stormwater and stormwater runoff will be infiltrated locally
at the point of generation. Potable water is provided by the
Dare County distribution system. The rear of the site is a
delineated regulatory wetland with an irregular boundary.
See the attached drawing:
C-1, Puraflo Active System and Details
DESIGN CRITERIA AND CONDITIONS
The design flow for the facility is a maximum of 480 GPD
based upon 4 bedrooms at normal occupancy. The site is
reported by the Dare County Health Department to have soil
wetness at 12 to 14 inches below the existing original grade,
and 24 inches of fill is required at the drainfield location.
The LTAR is 1.0 GPD/sf of Puraflo bed bottom area. A design
for the active Puraflo system is provided. Because the lot
was identified in the Dare County Registry Deed Book 41, Page
20, June 6, 1958, a repair area is not required (Regulation
.1945) and the minimum horizontal separation to a property
line is 5 feet (Regulation .1951).
All system components are located at or greater than 5 feet
from the nearest property line, at or greater than 5 feet
from the building foundations and at or greater than 35 feet
from regulatory wetlands.
All materials, supplies, procedures, workmanship and
installations shall comply with the latest editions and
amendments of:
North Carolina Building Code,
Laws and Rules for Sanitary Sewage Collection,
Treatment, and Disposal, Section .1900 of the North
4
Carolina Administrative Code, Title 10, Department of
Human Resources, Chapter 10, Health Services;
Environmental Health, Subchapter 10A, Sanitation,
Laws and Regulations applicable to General Contracting
in the State of North Carolina,
Sanitation rules and regulations of the Dare County
Health Department,
Respective manufacturers' instructions and accepted
industry standards of good practice, and
Bord na Mona recommendations and requirements for the
Puraflo Peat Biofilter.
All work shall be performed under the direct supervision
of a person properly registered with the Dare County
Health Department.
GENERAL
Backfill materials shall be clean and free of organic
material and trash or debris that may be harmful to any
system components.
All work shall cease and be held for inspection and approval
at appropriate hold points in accordance with the
requirements of the Dare County Health Department and the
engineer. The contractor shall provide reasonable prior
notice (minimum 24 hours) to the engineer of pending
inspection.
The contractor shall perform and certify all tests and shall
maintain a record of all tests results. Test results shall
be provided to the Engineer and the Owner upon request, and
shall be transmitted to the owner with the operations and
maintenance manuals.
5
The contractor shall be solely responsible for the conduct
and supervision of all work associated with this
specification.
Finish graded slopes for disturbed land shall not exceed 1:3
(rise:run) except as specified on the drawings.
All disturbed areas shall be stabilized and vegetated within
15 working days or 30 calendar days after cessation of land
disturbing activities.
BUILDING SEWERS
Wastewater from the building shall be conveyed to the septic
tank by gravity flow through PVC sewer pipes. Minimum slope
of the sewers shall be 1/4 inch per foot.
Sewers installed with a bury of less than 24 inches under
pavement or aggregate parking or drive areas shall be
schedule 80 PVC pipe and fittings. Sewers installed in
unpaved areas and protected from traffic or other severe
loads shall be Schedule 40 ABS or PVC pipe and fittings.
The following specifications or standards apply:
ABS Sewer Pipe
ABS-DWV
PSP PVC Sewer
PSM PVC Sewer
PVC-DWV
and Fittings
Pipe and Fittings
Pipe and Fittings
ASTM D 2751-73
ASTM D 2661-73
ASTM D 3033-73
ASTM D 3034-73
ASTM D 2665-73
Piping shall be installed on a smooth trench bottom of
undisturbed natural soil or compacted clean fill. All piping
shall be installed to the appropriate alignment, grade and
condition prior to backfilling or placing of encasement.
Prior to backfilling or placing of encasement the building
sewers shall pass a leakage test of not to exceed 100 gallons
leakage per day per inch of pipe diameter per mile of pipe
under a 5 foot minimum head for the section under test.
Visible or surfacing leakage shall be corrected and the pipe
retested.
6
Backfill shall be evenly placed and compacted in shallow
lifts not to exceed 6 inches loose to a depth of not less
than 4 inches above the top of the pipe. Backfill under or
within 5 feet of pavement or building footings or floor slabs
shall be placed in lifts not to exceed 10 inches loose and
each lift shall be wetted and thoroughly compacted prior to
installation of the subsequent lift. All backfill shall be
installed free of voids and shall be tamped. In no case
shall a backfill lift exceed 12 inches loose.
Care shall be taken during backfill and compaction operations
to maintain alignment and prevent damage to the piping and
joints. Backfill shall be brought up to the local grade.
SEPTIC TANK & PUMP TANK
The septic tank shall be a 1,000 gallon precast concrete
septic tank manufactured by Coastal Ready Mix bearing the
imprint STB-913 and shall be equipped with an outlet filter.
The pump tank shall be a 1,150 gallon precast concrete pump
tank manufactured by Coastal Ready Mix bearing the imprint
PT-91.
The septic tank shall be installed to allow 1/4 inch per foot
fall for the building sewer. Local grade at the tank or tank
elevation shall be adjusted as necessary to assure that the
top of the tank is a minimum of 6" below local grade. The
ground surface elevation from the house to the septic tank
inlet shall be sufficient to provide not less than 12 inch
cover over the building sewer to the septic tank in non-
traffic areas, and 24 inch cover under paved driveway or
parking areas. In the event that building sewer cover in
paved parking or drive areas is less than 24 inches, or cover
in unpaved parking or drive areas is less than 30 inches,
ductile iron pipe shall be used.
Pump tank inlet invert elevation shall be lower than the
outlet of the septic tank by a minimum of 1 inch plus 1/8
inch per foot fall in the connector pipe.
7
Excavations for the tanks shall be of sufficient size and
depth to allow unhindered installation of the tanks.
Building and deck foundations shall be protected from
collapse during installation of the tanks.
The tanks shall be installed level on a bed which has been
leveled and compacted and which is of sufficient size to
enable tank installation on the undisturbed prepared portion
of the bed.
Tanks shall be leakage tested by filling with clean water to
not less than 12 inches above any sidewall seam (using plugs
or fittings in inlets and outlets as appropriate). Such
level shall be maintained for not less than 24 hours by
making up water as necessary. The water level shall then be
monitored for 24 hours without adding water or other liquids
or materials. A drop in water level of more than 1 inch
shall cause the tank to be emptied and repaired or replaced
and then tested as a new tank. Backfill shall not be placed
above the tank bottom prior to satisfactory completion of the
test.
Backfill under and adjacent to tanks with undercut sides
shall be placed in lifts not to exceed 6 inches loose and
shall be wetted and thoroughly compacted until the fill
elevation has reached the vertical sides of the tanks.
Backfill adjacent to tanks for which the excavation is under
or within 5 feet of pavement or within 10 feet of building
footings or floor slabs shall be placed in lifts not to
exceed 10 inches loose and each lift shall be wetted and
thoroughly compacted prior to installation of the subsequent
lift. Care shall be taken during backfill and compaction
operations to prevent damage to the tanks. Backfill shall be
brought up to the local grade.
Manholes and risers shall be sealed against intrusion of
water or soil and shall be gas tight. Manhole risers shall
be brought up to 6 inches above grade and shall be odor free.
A 1-1/2" diameter vent pipe shall be installed through the
side or end wall of the pump tank at the top of the wall or
through a manhole riser wall. The vent pipe riser and
8
vacuum-breaker valve shall be located in a protected position
as shown on the drawings or as located in the field and
approved by the Engineer at the time of construction.
All tank penetrations shall be sealed to the opening through
the tank or manhole riser wall with non-shrink grout or
