Dear Mr. Kelly:
In accordance with your modification request received December 19, 2006, and subsequent
additional information received January 16, 2007, we are forwarding herewith Permit No. WQ0005790,
dated February 2, 2007, to the Town of Oak Island for the construction and continued operation of the
subject wastewater treatment and reclaimed water utilization system. The purpose of this modification is
to add seven (7) new zones of conjunctive -use reclaimed irrigation at the adjacent South Harbour Par-3
Golf Course.
Please pay special attention to the following new or updated conditions:
• Condition I.3. requires the abandonment of the existing irrigation well prior to the operation
of the South Harbor Golf Course reclaimed irrigation facility.
• Condition I-9.c- provides required setbacks for the new reclaimed golf course irrigation
zones,
Condition I.11. contains requirements for the golf course reclaimed water distribution,
storage, and utilization facilities, and
Condition IL8. lists irrigation rate limits for the new golf course irrigation zones.
This permit shall be effective from the date of issuance until January 31, 2012, shall void Permit
No. WQ0005790 issued December 7, 2004, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure to
establish an adequate system for collecting and maintaining the required operational information will
result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the

I. PERFORMANCE STANDARDS
Upon completion of construction and prior to operation of the South Harbour Golf Course
reclaimed irrigation facility, a certification 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. 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 permit, and shall provide a final certificate of completion
once the entire project has been -completed. Mail the Certification to the Land Application Unit,
1636 Mail Service Center, Raleigh, NC 27699-1636.
2. The Wilmington Regional Office, telephone number [phone], shall be notified at least
forty-eight (48) hours in advance of operation of the South Harbour Golf Course reclaimed
irrigation facility so that an in -place inspection can be made. Such notification to the regional
supervisor shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on
Monday through Friday, excluding State Holidays.
Prior to operation of the South Harbour Golf Course reclaimed irrigation facility, the existing golf
course irrigation well shall be permanently abandoned. Within thirty (30) days of abandonment, a
Well Abandonment Record (GW-30 form) shall be completed and mailed to the Aquifer
Protection Section at 1636 Mail Service Center, Raleigh, NC 27699-1636. The well must be
abandoned by either a North Carolina Certified Well Contractor, the property owner, or the
individual property lessee according to General Statutes 87-98.4(b)(2). If the abandonment is not
performed by a certified well contractor, the property owner or lessee must be a person as defined
by General Statutes 87-98.2(3), must physically perform the actual well abandonment activities,
and must abandon the well according to the North Carolina Well Construction Standards (15A
NCAC 2C .0113) and local county rules.
4. The high rate infiltration and reclaimed water irrigation facilities shall be effectively maintained
and operated at all times so that there is no discharge to the surface waters, nor any contamination
of ground waters, which will render them unsatisfactory for normal use. In the event that the
facilities fail to perform satisfactorily, including the creation of nuisance conditions or failure of
the irrigation area to adequately assimilate the wastewater, the Permittee shall take immediate
corrective actions including those actions that may be required by the Division of Water Quality
(Division), such as the construction of additional or replacement wastewater treatment and
disposal facilities.
5. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface water or ground water resulting from the operation of this facility.
6. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.
7. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
