application received October 5, 1998, and in conformity with the project plan, specifications, and other
supporting data subsequently filed and approved by the Department of Environment and Natural Resources
and considered a part of this permit.
This permit shall be effective from the date of issuance until January 31, 2004, and shall be subject to
the following specified conditions and limitations:
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 responsibility to track further construction approved under the same permit, and shall
provide a final certificate of completion once the entire roject has been completed. Mail the
Certification to the Non -Discharge Permitting Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. The Mooresville 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. 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.

The spray 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.
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.
The sand media of the recirculating, pressure -dosed, surface sand filter must comply with the
Division's sand specifications. The engineer's certification will serve as evidence that these
specifications have been met.
A leakage test shall be performed on the septic tank and dosing tank 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 tank capacity. The engineer's certification will serve as proof of compliance with this
condition.
7. If excavation into bedrock is required for the installation of the septic tank or sand filter, the pit
shall be lined with a 10 -mil synthetic liner.
8. A sanitary tee shall be installed on the effluent pipe of the septic tank. The engineer's certification
will serve as evidence that these specifications have been met.
9. 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.
10. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
11. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 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 treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for 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 spray irrigation areas 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.

II. OPERATION AND MAINTENANCE REOUIREMENTS
1. 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 to be in responsible charge (ORC) of the wastewater treatment facilities. The operator
must hold a 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 Il, III, and IV facility at least daily, excluding weekends and holidays,
