amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Mr. Richard E. Fox
Chatham County
FOR THE
construction and operation of a 360 GPD spray irrigation wastewater treatment and disposal system
consisting of a 1,000 gallon baffled septic tank, a 396 ftz unvented subsurface sand filter, a tablet
chlorinator, a 2,000 gallon storage/pump tank, and a 13,608 ft2 spray irrigation area to serve the Mr.

Resources and considered apart of this permit.
This permit shall be effective from the date of issuance until May 31, 2002 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. Mail the Certification to the Water Quality
Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC 27626-0535.
2. The Raleigh Regional Office, telephone number 919-571-4700, 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. 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, 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.
5. The sand media of the subsurface sand filter must comply with the Division's sand
specifications. The engineer's certification will serve as evidence that these specifications
have been met.
6. 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 North Carolina Division of
Water Quality.
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

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.
* It is the Division's understanding the developer intends to locate a pond on this site.
Please note the spray irrigation field must be located 100 feet from the proposed pond.
11. OPERATION AND_ MAINTENANCE REQUIREMENTS
The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee shall

of Title 15A, Chapter 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 Title 15A, Chapter 8A, .0202. 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

3. A suitable vegetative cover shall be maintained on the spray irrigation field.

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 spray field.

(12) month period at an instantaneous application rate not to exceed 0.24 inches per hour.
7. 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.
8. No type of wastewater other than that from the Lot #1 Residence in the Fox Subdivision
shall be sprayed onto the irrigation area.
9. In the event that the sprinkler heads fail to achieve the design diameter of 76 feet due to
obstructions, the obstructions shall be removed or the sprinkler heads shall be raised and
supported to such height that the design diameter is achieved.
10. No traffic or equipment shall be allowed on the disposal area except while installation
occurs or while normal maintenance is being performed.
11. The spray irrigation field shall be fenced with at least a two strand wire fence.

ground water protection will be established and an acceptable sampling reporting schedule
shall be followed.
2. The Permittee shall maintain records of all maintenance performed on the system and
