Town of Navassa
Lena Springs Estates Phase 1 Sewer
Wastewater Collection System Extension
Brunswick County
In accordance with your application received February 26, 2007, and additional information
received on March 21, 2007, we are forwarding herewith Permit No. WQ0030911, dated March 23, 2007,
to the Town of Navassa for the construction and operation of the subject wastewater collection system
extension. This permit shall be effective from the date of issuance until rescinded, shall void Permit No.
WQ0030911 issued October 20, 2006, and shall be subject to the conditions and limitations as specified
therein. This cover letter shall be considered a part of this permit and is therefore incorporated therein
by reference.
This modification adds an additional 1,100 linear feet of 8-inch gravity sewer to serve an
additional 29 residences. In addition, it allocates flow for an additional 14 residences on the previously
permitted gravity sewer.
By copy of this permit, the Brunswick County Building Inspections Department is hereby notified that
building or occupancy permits shall only be issued for the 60 residences as part of the Lena Springs
Estates Phase 1 project until a modified permit is issued by the Division indicating additional
connections. In addition, no certificates of occupancy are to be granted prior to the submittal of a
sealed engineer's certification per Condition 6 of this permit.
Please pay particular attention to Condition 14 regarding the permitting of this system after -the -tact and
that the use of 10-inch gravity sewer may not be able to be justified even in the future.
Please note the following standard conditions that are contained in this permit.
Condition 3: Requires that the wastewater collection facilities be properly operated and
maintained in accordance with 15A NCAC 2T .0403 or any individual system -wide
collection system permit issued to the Permittee.

Declarations, and Bylaws that have been appropriately filed shall be submitted with the
certification.
7. A copy of the construction record drawings and pump station designs, if applicable, shall be
maintained on file by the Permittee for the life of the wastewater collection facilities.

215.6A through § 143-215.6C.
9. Gravity sewers installed greater than ten percent below the minimum required slope per the
Division's Gravity Sewer Minimum Design Criteria shall not be acceptable and shall not be certified
until corrected. If there is an unforeseen obstacle in the field where all viable solutions have been
examined, a slope variance can be requested from the Division with firm supporting
documentation. This shall be done through a permit modification with fee. Such variance requests
will be evaluated on a case -by -case basis. Resolution of such request shall be evident prior to
completing and submitting the construction certification.

10. In the event that the wastewater collection facilities fail to perform satisfactorily, including the
creation of nuisance conditions, the Permittee shall take immediate corrective action, including
those as may be required by this Division, such as -the construction of additional or replacement

NCAC 2B .0200, erosion and sedimentation control requirements in 15A NCAC Ch. 4 and under the
Division's General Permit NCGO10000, and any requirements pertaining to wetlands under 15A
NCAC 2B .0200 and 15A NCAC 2H .0500.
12. Noncompliance Notification:
The Permittee shall verbally report to a Division of Water Quality staff member at the Wilmington
Regional Office, telephone number (910) 796-7215, as soon as possible, but in no case more than
24 hours or on the next working day, following the occurrence or first knowledge of the occurrence
of either of the following:
a. Any failure, due to known or unknown reasons, that renders the system incapable of
adequate wastewater transport, such as mechanical or electrical failures of pumps, line
blockage or breakage, etc.; or
b. Any failure of a pumping station or sewer line resulting in a by-pass of any wastewater directly
to receiving waters from the station or sewer line.
Voice mail messages or faxed information is permissible, but shall NOT be considered as the initial
verbal report. Overflows and spills occurring outside normal business hours may also be reported to
the Division of Emergency Management at telephone number (800) 858-0368 or (919) 733-3300.
Persons reporting any of the above occurrences shall file a spill report by completing Part I of Form
CS-SSO (or the most current Division approved form), within five days following first knowledge of the
occurrence. This report shall outline the actions taken or proposed to ensure that the problem does
not recur. Part II of Form CS-SSO (or the most current Division approved form) can also be
completed to show that the SSO was beyond control.
13. Each pump station including simplex stations shall be clearly and conspicuously posted with the
telephone number and name of the owner/operator of the sewer system and instructions to call
the number in the event of alarm activation.
14. The original system was permitted after -the -fact and issuance of this permit does not relieve The
Town of Navassa of a potential enforcement action for construction of the sewers included herein
prior to the issuance of the permit to do so. In addition, the installed system utilized 10-inch gravity
sewer. This size line is not justified based on the current design flow and may not be able to be
justified in the future without substantial additional flow being connected upstream.

CERTIFICATION: This project shall not be considered complete nor allowed to operate until the Division has
received this Engineer's Certification and all required supporting documentation. Consequently, the PERMITTEE
should submit this certification in a manner that documents proof -of -receipt by the Division.
Complete and submit this unmodified form to the permit issuing regional office with the following:
• One oriainally sealed/signed set of the project record drawings (plan & profile views of sewer lines & force
mains) of the wastewater collection system extension. Record drawings are defined as the design drawings
that are marked up or annotated with after construction information and show required buffers, separation
distances, material changes, and other utilities including water lines, stormwater systems, etc.
• One oriainally sealed/signed set of the supporting pump station design calculations (selected pumps, system
curve, operating point, buoyancy calculations, available storage if portable generator(s) or storage greater
than longest post three year outage reliability option selected) for any pump stations permitted under this
permit
• Changes to the project that do not result in non-compliance with this permit, regulations, or the minimum
design criteria should be clearly identified on the record drawings, on this certification in the space provided, or
in written summary form.
PRIOR TO CERTIFICATION (FINAL OR PARTIAL): Permit modifications are required for any changes resulting in non-
compliance with this permit (including total pipe length increase of 10%, or greater, increased flow, or increases in
the number/type of connections), regulations, or the minimum design criteria. Requested modifications or
variances to the minimum design criteria will be reviewed on a case -by -case basis and each on its own merit.
Please note that variances to the minimum design criteria should be requested and approved during the permitting
process prior to construction. After -construction requests are discouraged by the Division and may not be
approved, thus requiring replacement or repair prior to certification & activation.
