I. PERFORMANCE STANDARDS
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, the approved plans and specifications, and other supporting materials. If
this project is to be completed in phases and partially certified, you shall retain the responsibilityto
track further construction approved under the same permit, and shall provide a final certificate of
completion once the entire project has been completed. Mail the Certification to the Non -Discharge
Permitting Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
The Raleigh Regional Office, telephone number [phone], 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.

3. 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.

The drip irrigation facilities shall be effectively maintained and operated at all times so that there is no
discharge to the surface waters, nor any contamination of ground waters which will render them
unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including the
creation of nuisance conditions or failure of the irrigation area to adequately assimilate the wastewater,
the Permittee shall take immediate corrective actions including those actions that may be required by
the Division of Water Quality (Division), such as the construction of additional or replacement
wastewater treatment and disposal facilities.
5. The residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
6. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.

a. 100 feet between wetted area and any residence or places of public assembly under separate
ownership,
b. 50 feet between wetted area and property lines,
c. 100 feet between wetted area and wells,
d. 50 feet between wetted area and drainageways or surface water bodies,
e. 50 feet between wetted area and public right of ways,
f. 100 feet between wastewater treatment units and wells, and
g. 50 feet between wastewater treatment units and property lines.
8. A leakage test shall be performed on all tanks and the sandfilter to insure that any exfiltration occurs at
a rate which does not exceed twenty (20) gallons per twenty-four (24) hours per 1,000 gallons of
capacity. The engineer's certification will serve as proof of compliance with this condition.
H. OPERATION AND MAINTENANCE REQUIREMENTS
I . The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Water Pollution Control System Operators Certification
Commission (WPCSOCC), the Permittee shall employ a certified wastewater treatment plant operator

certificate of the type and grade at least equivalent to or greater than the classification assigned to the
wastewater treatment facilities by the WPCSOCC. The Permittee must also employ a certified back-up
operator of the appropriate type and grade to comply with the conditions of 15A NCAC 8A .0202. The
ORC of the facility must visit each Class I facility at least weekly and each Class II, III, and IV facility
at least daily, excluding weekends and holidays, and must properly manage and document daily
operation and maintenance of the facility and must comply with all other conditions of 15A NCAC 8A
.0202. Once the facility is classified, the Permittee must submit a letter to the WPCSOCC which
designates the operator in responsible charge within thirty days after the wastewater treatment facilities
are 50% complete.
A suitable year-round natural cover shall be maintained.
4. Irrigation shall not be performed during inclement weather or when the ground is in a condition that
will cause runoff.
5. Adequate measures shall be taken to prevent wastewater runoff from the drip field.
6. 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.
7. The application rate shall not exceed a cumulative loading of 21.32 inches over any twelve (12) month
period at an instantaneous application rate not to exceed 0.25 inches per hour.

shall be sprayed onto the irrigation area.
9. No traffic or equipment shall be allowed on the disposal area except while installation occurs or while
normal maintenance is being performed.
10. Public access to the land application sites shall be controlled during active site use.
III. MONITORING AND REPORTING REQUIREMENTS

by the Division to ensure surface and ground water protection will be established and an acceptable
sampling reporting schedule shall be followed.
