conditions and limitations:
I. PERFORMANCE R
Upon completion of construction and prior to operation of this permitted facility, a
certification must be received from a professional engineer certifying that the permitted
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 Washington Regional Office, phone no. 919/"946-6481, shall be notified at least forty-
eight (48) hours in advance of backiilling 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. 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 construction of additional or replacement
wastewater treatment or disposal facilities.
4. 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.
5. This permit shall become voidable if the soils fail to adequately assimilate 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may be rescinded unless the facilities are installed, maintained, and operated in a manner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.
6. Adequate measures shall be taken to divert stormwater from the disposal area and prevent
wastewater runoff from the disposal area.
7. The residuals 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.
S. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.
9. The following buffers shall be maintained, except where alternate buffers are specifically
described on the approved submittal documents:
a) 100 feet between disposal area and any public or private water supply including
wells

this waste treatment and disposal system. These buffers are not intended to prohibit or
prevent modifications, which are required by the Division, to improve performance of the
existing treatment facility. These buffers do, however, apply to modifications of the
treatment and disposal facilities which are for the purpose of increasing the flow that is
tributary to the facility. These buffers do apply to any expansion or modification of the
facilities and apply in instances in which the sale of property would cause any of the
buffers now complied with, for the treatment and disposal facilities, to be violated. The
applicant is advised that any modifications to the existing facilities will require a permit
modification.
