11. An annual plant tissue analysis shall be conducted on each irrigation field (i.e., Fields I through 34),
and the results maintained on file by the Permittee for a minimum of five years.
12. An annual representative soils analysis (Standard Soil Fertility Analysis) shall be conducted on each
irrigation field (i.e., Fields i through 34), and the results maintained on file by the Permittee for a
minimum of five years. The Standard Soil Fertility Analysis shall include, but is not necessarily
limited to, the following parameters:
Acidity
Manganese
Potassium
Calcium
Percent Humic Matter
Sodium
Copper
pH
Zinc
Magnesium
Base Saturation (by calculation)
Phosphorus
Cation Exchange Capacity
Exchangeable Sodium Percentage
13. Noncompliance Notification:
The Permittee shall report by telephone to 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 worming day
following the occurrence or first knowledge of the occurrence of any of the following:
a. Any occurrence at the wastewater treatment facility which results in the treatment of significant
amounts of wastes which are abnormal in quantity or characteristic, such as the dumping of the
contents of a sludge digester; the known passage of a slug of hazardous substance through the
facility; or any other unusual circumstances including ponding in the irrigation areas, runoff from
the irrigation areas or high -rate infiltration basin breakout.
b. Any process unit failure, due to known or unknown reasons, that render the facility incapable of
adequate wastewater treatment such as mechanical or electrical failures of pumps, aerators,
compressors, etc.
c. Any failure of disposal system resulting in a by-pass directly to receiving waters.
WQ0005849 Version 2.3 Shell Version 070612 Page 10 of 13

d. Any time that self -monitoring information indicates that the facility has gone out of compliance
with its permit limitations including, but not limited to, freeboard measurements, effluent
limitations, exceedances of groundwater standards, or overloading of any infiltration/irrigation
area.
For any emergency that requires immediate reporting (e.g., discharges to surface waters, imminent
failure of a storage structure, etc.) outside normal business hours must be reported to the Division's
Emergency Response personnel at telephone number [phone], [phone], or (919) 733-
3300. Persons reporting such occurrences by telephone shall also file a written report in letter form
within five (5) days following first knowledge of the occurrence. This report must outline the actions
taken or proposed to be taken to ensure that the problem does not recur.
V. INSPECTIONS
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 ieachate.
VI. GENERAL CONDITIONS
1. Failure to abide by the conditions and limitations contained in this permit may subject the Permittm
to an enforcement action by the Division in accordance with North Carolina General Statute 143-
215.6A to 143-215.6C.
2. This permit shall become voidable unless the facilities are constructed in accordance with the
conditions of this permit, the approved plans and specifications, and other supporting data.
3. This permit is effective only with respect to the nature and volume of wastes described in the
application and other supporting data. No variances to applicable rules governing the construction
and / or operation of the permitted facilities are granted unless specifically requested and granted in
this permit.
4. The issuance of this permit does not exempt the Permittee from complying with any and all statutes,
rules, regulations, or ordinances, which may be imposed by other government agencies (local, state,
and federal) that have jurisdiction. Of particular concern to the Division are applicable river buffer

5. In the event there is a desire for the facilities to change ownership, or there is a name change of the
Permittee, a formal permit request must be submitted to the Division on official Division forms,
documentation from the parties involved, and other supporting materials as may be appropriate. The
approval of this request will be considered on its merits and may or may not be approved. The
Permittee of record shall remain fully responsible for compliance until a permit is issued to the new
owner.

pH shall he made after purging and prior to sampling for the remaining parameters.
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top of
casing) of all monitoring wells shall be surveyed relative to a common datum.
4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230I), PQL at 0.5 µg/L or less
b. Standard Method 6210D, PQL at 0.5 pg/L or less
C. EPA Method 8021, Low Concentration, PQL at 0.5 µg/L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 µglL or less
C. Another nictliod with prior approval by the Aquifer Protection Section Chief
Any anethod 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 6230D.
C. The method used inust 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 MDL but below the PQL 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 [phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. If TOC concentrations greater than 10 mg/l 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_ Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to [lie additional sampling and analysis as described above.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure I and this attachment.
