facility has been installed in accordance with this permit and the approved plans and
specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box
29535, Raleigh, NC 27626-0535.
2. The Wilmington Regional Office, phone no. 919/395-3900, shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities 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.
3. This permit shall become voidable if the soils fail to adequately absorb the wastes and may
be rescinded unless the facilities are installed, maintained, and operated in a manner which
will protect the assigned water quality standards of the surface waters and ground waters.

4. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as
may be required by this Division, such as the construction of additional or replacement
treatment or disposal facilities.
5. The issuance of this permit shall not relieve the Permittee of the responsibility for damages
to surface or groundwaters resulting from the operation of this facility.
6. Any sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner approved by the North Carolina Division of
Environmental Management.
7. Diversion or bypassing of the untreated groundwater from the treatment facilities is
prohibited.
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee shall
employ a certified wastewater treatment plant operator to be in responsible charge of the
wastewater treatment facilities. The operator must hold a certificate of the type and grade at
least equivalent to the classification assigned to the wastewater treatment facilities by the
Certification Commission. Once the facility is classified, the Permittee must submit a letter
to the Certification Commission which designates the operator in responsible charge within
thirty days after the wastewater treatment facilities are 50% complete.
3. The facilities shall be effectively maintained and operated as a non -discharge system to
prevent the discharge of any wastewater resulting from the operation of this facility.
III. MONITORING AND REPORTINQ REQUIREMENTS
Any monitoring deemed necessary by the Division of Environmental Management to insure
surface and ground water protection will be established and an acceptable sampling
reporting schedule shall be followed.
2. Noncompliance Notification:
The Permittee shall report by telephone to the Wilmington Regional Office, telephone no.
919/395-3900, 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 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 basin or tank; 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 facility
incapable of adequate wastewater treatment such as mechanical or electrical failures
of pumps, aerators, compressors, etc.

C. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-
pass directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility is not in
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 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.
1. Monitoring wells U1-lA, U1-5A, and U1-3A shall be sampled semiannually in March and
September for EPA methods 602 and 610. Results of the sampling should be forwarded to
the N.C. Division of Environmental Management on Form GW-59 (Compliance and
Monitoring Report From) every April and October.
2. All components of the groundwater recovery, treatment and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.
3. The effluent from the treatment system shall be sampled every month for EPA Methods 602
and 610. The effluent shall be sampled at a point prior to discharge to the infiltration
gallery. The results of the sampling and analysis shall be sent to the Groundwater Section
in the Wilmington Regional Office, within 30 days of sample collection.
4. The groundwater recovery treatment and disposal system shall be inspected weekly. If it is
determined that the system is malfunctioning, all repairs should be made as soon as
possible and reported to the Wilmington Regional Office.
5. The Compliance Boundary for the disposal system is specified by regulations in 15 NCAC
2L, Groundwater Classifications and Standards. An exceedance of Groundwater Quality
Standards beyond the Compliance Boundary is subject to penalty provisions applicable
under General Statute 143-215.6(1)a. The sale of property, by the Permittee, which is
within or contiguous to the disposal system site may alter location of the Compliance
Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the groundwater infiltration gallery, or 50 feet
within the property boundary.
If the title to any property which may affect the location of the Compliance Boundary is
changed, the Permittee shall notify the DEM Director within 14 days. The Director shall
then establish a modified Compliance Boundary which will be done as a modification to the
Permit.
e REVIEW Rni1I�D
NCAC Groundwater"�"_"' "ARY for the disposal system is specified by regulations in 15
Classifications and Standards. A REVIEW BOUNDARY is
established around disposal systems midway between the Compliance Boundary and the
perimeter of the waste disposal area. When the concentration of any substance equals or
exceeds the maximum allowable concentration of that substance at the REVIEW
BOUNDARY, as determined by monitoring, the permittee shall either (i) demonstrate,
through predictive calculations or modeling, that natural site conditions, facility design and
operational controls will prevent a violation of standards at the Compliance Boundary; or,
(ii) submit a plan for the alteration of existing site conditions, facility design or operational

controls that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
6. Any additional groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided
1. Adequate inspection, maintenance and cleaning shall be provided by the Permittee to insure
proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the groundwater recovery and treatment
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
