minute (GPM) pumps, dual 194,000 gallon extended aeration basins with coarse bubble diffusers, dual
34,200 gallon circular clarifiers with scum baffles, an 8,000 gallon primary disinfection tank with a
chlorine treatment system, four (4) 43.5 square foot ff ) ternary filters with a 14,000 gallon mudwell and a
13,050 gallon clearwell, a 7,800 gallon secondary disinfection tank with an ultraviolet (UV) disinfection
system, a 5,300 gallon effluent pump tank with dual 435 GPM pumps, audible and visual alarms, a 64,700
gallon aerated sludge holding tank, a 260 cubic foot per minute (CFM) equalization blower, three (3) 1,000
CFM aeration blowers and a 174 CFM filter blower, an onsite emergency generator with an automatic
transfer switch, a UV disinfection automatic sampler, a turbidity monitor, flow meter, and all other
necessary pipes, pumps, valves and appurtenances for proper operation of a wastewater treatment plant.
Phase I will also include a 2.35 million gallon (MG) lined five (5) day upset pond, a 13 MG effluent
storage pond, approximately 7,500 linear feet of new six-inch force main connecting to the existing pump
station and 6-inch force main to transfer wastewater to the new treatment system, approximately 14,500
linear feet of 12-inch effluent force main to discharge at the existing irrigation pump station and
modifications of the existing golf course system to allow for effluent reuse on 18 holes of the River
Landing Golf Course.
Phase II consists of the construction and operation of a second 250,000 GPD package treatment plant
identical to the wastewater treatment system listed in Phase I (above).
This facility has been approved to serve 1,236 three bedroom homes and an additional 25,000 GPD
consisting of the clubhouse and other uses for Duplin Land Utilities, River Landing Development and Golf
Course with no discharge of wastes to the surface waters, pursuant to the application received February 28,
2007, and subsequent additional information received by the Division of Water Quality (Division), and in
conformity with the project plan, specifications, and other supporting data subsequently filed and approved

attached form) must be received from a professional engineer certifying that the permitted facility has
been installed in accordance with this permit, the approved plans and specifications, and other
supporting materials including the location of all monitoring wells as applicable. If this project is to
be completed in phases and partially certified, you shall retain the responsibility to track further
construction approved under the same Kermit, and shall provide a final certificate of completion once
the entire project has been completed. Mail the Certification to the Aquifer Protection Section,
Division of Water Quality, 1636 Mail Service Center, Raleigh, NC 27699-1636.
2. The Wilmington Regional Office, telephone number [phone],[phone] shall be notified
at least 48 hours in advance (excluding weekends and holidays) of operation of the installed facilities

a licensed Professional Engineer and submitted to the appropriate regional office 30 days prior to
installation. The flow -measuring device shall be installed prior to operation.
5. Upon completion of construction and prior to operation of this permitted facility, field identification
must be redone (each Hole with each soil type; for example, Hole#2 contains two different soil types,
therefore, there are 2 areas that should be identified as field 2A and 213). An updated map with soil
mapping units and the new acreage for each field must also be submitted to the Aquifer Protection
Section, Division of Water Quality, 1636 Mail Service Center, Raleigh, NC 27699-1636.
6. Upon completion of construction and prior to operation of this permitted facility, the permittee shall

system or three copies of a letter from the NC Utilities Commission's Public Staff that states that an
application for a franchise has been received, that the service area is contiguous to an existing
franchised area, and/or that franchise approval is expected. The required documents shall be
submitted to the Aquifer Protection Section, Division of Water Quality, 1636 Mail Service Center,
Raleigh, NC 27699-1636.
7. No later than six months prior to the expiration of this permit, the Permittee shall request renewal of
this permit on official Division forms. Upon receipt of the request, the Division will review the
adequacy of the facilities described therein, and if warranted, will extend the permit for such period of
time and under such conditions and limitations as it may deem appropriate. Please note that Rule
15A NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal
application.
8. If Phase I of the permitted treatment system is not constructed and certified prior to renewal, the
Permittee will update the Division on the need of the system.

level readings obtained from the monitor well(s) near the site or auger boring(s), which must be done within
24 hours, prior to application of wastewater. Any open borings must be properly filled with native soil, prior
to application to decrease the chance of any waste contaminating the groundwater.
2. Five-day Detention Basin Liner Requirements:
The basin shall have either a liner of natural material at least one (1) foot in thickness and having a hydraulic
conductivity of no greater than 1 x 10"6 centimeters per second when compacted, or a synthetic liner of
sufficient thickness to exhibit structural integrity and an effective hydraulic conductivity no greater than that
of the natural material liner, according to 15A NCAC 2T .0908(f).
3. Additional Requirements:
Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
1. Adequate inspection and maintenance shall be provided by the Permittee to ensure proper operation
of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities to prevent
malfunctions and deterioration, operator errors and discharges which may cause or lead to the release
of wastes to the environment, a threat to human health, or a nuisance. The Permittee shall keep an
inspection log or summary including at least the date and time of inspection, observations made, and
any maintenance, repairs, or corrective actions taken by the Permittee. This log of inspections shall
be maintained by the Permittee for a period of five years from the date of the inspection and shall be
made available upon request to the Division or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division may, upon presentation of
credentials, enter and inspect any property, premises or place on or related to the disposal site or
facility at any reasonable time for the purpose of determining compliance with this permit; may
inspect or copy any records that must be maintained under the terms and conditions of this permit,
and may obtain samples of groundwater, surface water, or leachate.
VII. GENERAL CONDITIONS
1. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee
to an enforcement action by the Division in accordance with North Carolina General Statute 143-
215.6A to 143-215.6C.

owner.
6. The Permittee shall retain a set of approved plans and specifications for the life of the facilities
permitted herein.
7. The Permittee shall maintain this permit until all permitted facilities herein are properly closed or
permitted under another permit issued by the appropriate permitting authority.
