the certification to the Wilmington Water Quality Supervisor, 7225 Wrightsville Ave.,
Wilmington, N. C. 28403.
6. Upon the availability of a municipal or regional sewerage collection system, the subject
wastewater treatment facilities shall be abandoned and all wastewater discharged into the
municipal or regional sewerage system.
7. The facilities shall be effectively maintained and operated at all times so that there is no
discharge to the surface waters nor any contamination of groundwaters which will render
them unsatisfactory for normal use.
8. In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions, or failure of the disposal area to adequately absorb the wastewater, the Permittee
shall take such immediate corrective action as may be required by this Division, including the
construction of additional or replacement wastewater treatment or disposal facilities.
9. Any monitoring deemed necessary by the Division of Environmental Management to insure
surface and groundwater protection will be established and an acceptable sampling reporting
schedule shall be followed.
10. The sludge generated from these treatment facilities must be disposed of in accordance with
General Statute 143-215.1 and in a manner which is approved by the North Carolina
Division of Environmental Management. A sludge management plan must be
submitted to the Wilmington Regional Office within ninety days of the issuance of this
permit.

prohibited.
12. The Permittee, at least six (6) months prior to the expiration of this permit, shall request its
extension. Upon receipt of the request, the Commission will review the adequacy of the
facilities described therein, and if warranted, will extend the Permit for such period of time
and under such conditions and limitations as it may deem appropriate.
13. The permittee shall employ a certified wastewater treatment plant operator to be in
responsible charge of the wastewater treatment facilities. Such operator must hold a
certificate of the grade ai least equivalent to the classification assigned to the wastewater
treatment facilities by the Certification Commission.
14. 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.
15. 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.

16. No traffic or equipment shall be allowed on the disposal area except while installation occurs
or while normal maintenance is being performed.
17. An acceptable reserve area, equal in size to the approved disposal area, shall be maintained at
all times.

disposal site may alter the location of the Perimeter of Compliance.
34. For facilities permitted prior to December 30, 1983, the compliance perimeter is
established at a distance of 500 feet from the subsurface disposal mound or the property
boundary, whichever is less.
35. If the title to any property which may affect the boundary of the Perimeter of Compliance is
changed, the Permittee shall notify the Division Director within 14 days. The Director shall
then establish a modified Perimeter of Compliance and shall issue a modified permit, as
appropriate.

36. The permittee shall inspect all wastewater collection, 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,
