NC Division of Water Quality
Water Quality Section
Non -Discharge Compliance/Enforcement Unit
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Noncompliance Notification:
The Pernvttee shall report by telephone to the Wilmington Regional Office, telephone number (910)
395-3900, 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 any of the following:
a. Any occurrence at the facilities that 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.
b. Any process unit failure, due to known or unknown reasons, that render the facilities incapable of
adequate wastewater treatment, such as mechanical or electrical failures of pumps; aerators;
compressors; etc.
c. Any failure of the facilities that results in a bypass directly to receiving waters without treatment of
all or any portion of the influent to the facilities.
d. Any time that self -monitoring information indicates that the facilities have gone out of compliance
with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letterform 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.
IV. GROUNDWATER REQUIREMENTS
No irrigation of wastewater effluent/reclaimed water on the spray irrigation/reclaimed water utilization
facilities shall be undertaken when the seasonal high water table is less than three feet below the land
surface.
2. Until the existing spray irrigation facilities are modified such that they receive wastewater effluent
meeting the reclaimed water quality criteria only (i.e., following the Phase III construction), the six
existing groundwater monitoring wells (i.e., MW-I, MW-2, MW-3, MW-4, MW-5, and MW-6) shall
be sampled every March, July, and November for the following parameters:
PH Total Organic Carbon (TOC)
Total Ammonia -Nitrogen (NH3 -N) Water Level
If TOC concentrations greater than 10 milligrams per liter are detected in any downgradient
groundwater monitoring well, additional groundwater sampling and analysis shall be conducted to
identify the individual constituents comprising the TOC concentration. If the TOC concentration in the
background (i.e., upgradient) groundwater monitoring well exceeds 10 milligrams per liter, this
concentration shall be taken to represent the naturally -occurring TOC concentration in the
groundwater. Any exceedance of this naturally -occurring TOC concentration in downgradient wells
shall be subject to additional groundwater sampling and analysis as described above.
11

The measurement of water levels shall be made prior to sampling the groundwater for the remaining
parameters. The depth to water in each groundwater monitoring well shall be measured from the
surveyed point on the top of the casing.
The results of the sampling and analysis shall be received on the "Groundwater Quality Monitoring:
Compliance Report Form" (i.e., GW-59 Form) on or before the last working day of the month
following the sampling month at the following address:
NCDENR-DWQ
Groundwater Section
Permits and Compliance Unit
1636 Mail Service Center
Raleigh, North Carolina 27699-1636
3. Prior to constructing and operating the spray irrigation/reclaimed water utilization facilities proposed
with the Phase III construction, the six groundwater monitoring wells, MW-1, MW-2, MW-3, MW-4,
MW-5, and MW-6 shall have their wellheads secured in order to prevent access. This restriction of
access may be accomplished by attaching a padlock that would secure a metal wellcap to the protective
case or by some other means acceptable to the Groundwater Section. The wells shall be further secured
by placing a compatible watertight cap or seal onto the riser pipe in order to prevent potential
contamination from entering them.
4. The COMPLIANCE BOUNDARY for disposal systems not receiving reclaimed water shall be as
specified by regulations in 15A NCAC 2L (i.e., "Groundwater Classifications and Standards"). The
Compliance Boundary for disposal systems individually permitted after December 31, 1983 shall be
established at either (1) 250 feet from the waste disposal area, or (2) 50 feet within the property
boundary, whichever is closest to the waste disposal area. An exceedance of groundwater quality
standards at or beyond the Compliance Boundary shall be subject to immediate remediation action in
addition to the penalty provisions applicable under North Carolina General Statute § 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY shall be established around disposal
systems not receiving reclaimed water midway between the Compliance Boundary and the perimeter of
the waste disposal area. Any exceedance of standards at the Review Boundary shall require
remediation action on the part of the Permittee.
The COMPLIANCE BOUNDARY and REVIEW BOUNDARY for disposal systems receiving
reclaimed water shall be asspecified by 15A NCAC 2L. For systems utilizing reclaimed water, 15A
NCAC 2H .0219 (k) specifies that both the Compliance Boundary and the Review Boundary shall be
established at the property line. An exceedance of groundwater quality standards at or beyond the
compliance boundary is subject to immediate remediation action in addition to the penalty provisions
under North Carolina General Statute § 143-215.6A(a)(1).
6. Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
V. INSPECTIONS

2. The Permittee or his designee shall inspect the wastewater treatment and spray irrigation/reclaimed
water utilization facilities to prevent malfunctions and deterioration, operator errors, and discharges
that 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 three 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 wastewater treatment
and spray irrigation/reclaimed water utilization facilities at any reasonable time for the purpose of
