This permit shall be effective from the date of issuance until July 31, 2013, shall void Permit No.
WQ0005233 issued August 11, 2006 and shall be subject to the following specified conditions and
limitations:
I. SCHEDULES
1. A gauge to monitor waste levels in the stabilization lagoon and polishing and storage pond shall be
installed within 60 days of permit issuance/prior to operation. Caution shall be taken not to damage
the integrity of the liner (if present) when installing the gauge.
2. No later than ninety (90) days following the issuance of this permit, the Permittee shall

facultative lagoon will be replaced or repaired as well as an evaluation of the integrity of the
polishing/storage pond liner..
WQ0005233 Version 3.1 Shell Version 100209 Page 1 of 9
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 renew the permit for such period of
time and under such conditions and limitations as it may deem appropriate. Please note Rule 15A
NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal
application.
4. In accordance with 15A NCAC 02H .0404(e), if the subject wastewater treatment or disposal
facilities are in noncompliance with the terms and conditions of this permit, governing statutes or
regulations, the subject facilities shall be connected to an operational publicly owned wastewater
collection system within 180 days of its availability. Prior to the initiation of these connection
activities, appropriate Division approval shall be received.
II. PERFORMANCE STANDARDS
The subject non -discharge facilities shall be effectively maintained and operated at all times so there
is no discharge to surface waters, nor any contravention of groundwater or surface water standards.
In the event the facilities fail to perform satisfactorily, including the creation of nuisance conditions
due to improper operation and maintenance, or failure of the irrigation areas to adequately assimilate
the effluent, the Permittee shall take immediate corrective actions including Division required actions,
such as the construction of additional or replacement wastewater treatment or disposal facilities.
2. This permit shall not relieve the Permittee of their responsibility for damages to groundwater or
surface water resulting from the operation of this facility.
3. Effluent limitations shall not exceed those specified in Attachment A.
4. Application rates, whether hydraulic, nutrient or other pollutant, shall not exceed those specified in
Attachment B.
5. A usable green area shall be maintained for effluent disposal. The green area shall have the capability
of accommodating the facility's average daily flow without exceeding the green area loading rates.
As defined in 15A NCAC 02H .0404(g)(7), a "green area" is an area suitable for waste disposal,
either in its natural state or which has been modified by planting a vegetative cover of grasses or low
growing shrubbery.
6. The compliance boundary for the disposal system shall be specified in accordance with 15A NCAC
02L .0107(b). This disposal system was individually permitted on or after December 30, 1983;
therefore, the compliance boundary is established at either 250 feet from the effluent disposal area, or
50 feet within the property boundary, whichever is closest to the effluent disposal area. An
exceedance of groundwater standards at or beyond the compliance boundary is subject to remediation
action according to 15A NCAC 02L .0106(d)(2) as well as enforcement actions in accordance with
North Carolina General Statute 143-215.6A through 143-215.6C.
7. In accordance with 15A NCAC 02L .0108, the review boundary is established midway between the
compliance boundary and the effluent disposal area. Any exceedance of groundwater standards at the
review boundary shall require action in accordance with 15A NCAC 02L .0106.
8. The Permittee shall apply for a permit modification to establish a new compliance boundary prior to
any sale or transfer of property affecting a compliance boundary.
In accordance with 15A NCAC 02L .0107(d), no wells, excluding Division approved monitoring
wells, shall be constructed within the compliance boundary except as provided for in 15A NCAC 02L
.0107(g).

c. Reserves the right of the Permittee or the State to enter the property within the compliance
boundary for purposes related to the permit.
The Director may terminate the easement when its purpose has been fulfilled or is no longer needed.
11. The facilities permitted herein shall be constructed according to the following setbacks:
a. The setbacks for irrigation sites permitted prior to September 1, 2006 shall be as follows (all
distances in feet):
i. Anv habitable residence or place of public assembly under separate ownership: 400

e. Another method with prior approval by the Aquifer Protection Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ certified to run any method used.
b. The method used must, at a minimum_ include all the constituents listed in Table Vlll of Standard Method 62301).
C. The method used must provide a PQL of 0.5 µg/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents
detected above the MD[, but below the PQI, of 0.5 µg/L must be qualified (estimated) and reported.
5. if any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Wilmington Regional Office Aquifer Protection Supervisor, telephone
number (910)796-7215. must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. if TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/[, this concentration will be taken to represent the naturally occurring
TOC concentration. AnN, exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
Monitoring wells shall he reported consistent with the nomenclature and location information provided in Figure 1 and this attachment.
